A growing number of studies indicate that self-regulated learning plays a significant role in students' academic achievement. However, research studies on design studio education in self-regulated learning are under-researched globally, including in Turkey. In this study, I developed a self-regulated learning intervention for industrial design studio education and examined its impact on students' self-regulated learning strategies and design performance. Twenty six third-year industrial design students were tracked in a mixed-method research study conducted during a design studio course. Following the study, quantitative and qualitative data were collected from the students using self-report questionnaires and interviews. The jury grades of the students in the experimental group were compared with the grades of the students in the control group. Integrated data analysis indicated that activities for promoting self-regulated learning strategies such as goal-setting, self-monitoring, self-evaluation, self-efficacy, and seeking help and information in design studios can assist design students to improve their strategy use and design performance.

In this study, it was aimed to reveal the current situation by determining the career anxiety levels and career stress, together with the restrictions during the COVID-19 pandemic process in the Y and Z generations. The study consists of 346 (Ageaverage= 22.47±3.31) volunteers who study in the Faculties of Sports Sciences and Health Sciences located in 3 different provinces of Turkey. Data from the study was collected online via 'Google Forms' using the 'Personal Information Form' and 'Scale of Career Stress' using a screening model from quantitative research methods.

According to the findings, the participants' scores on the career stress scale based on career "uncertainty and lack of knowledge" (p <0.001, Cohen's d = 0.56), "external conflict" (p <0.001, Cohen's d = 0.47), "Pressure to find employment "(p <0.002, Cohen's d = 0.33) and" career stress scale total "(p <0.001, Cohen's d = 0.52) scores were found to be statistically significant. There is a relationship between the career anxiety felt by the generation Y during the COVID-19 Pandemic (p = 0.20; p <0.05). As a result; Career stress is a situation that may arise at every stage of the career ladder. Career stress can also be a driving force for career advancement. Hence, career stress has its positives as well.

The aim in the current study is to examine the conceptualizations of zero in arithmetic operations among students with learning disabilities (LD) and no learning disabilities (N-LD). The similarities and differences in the understandings of students with LD and N-LD of zero in arithmetical operations will be discussed. The study is a multiple case study with a qualitative research design. Six students, 3 students with LD and 3 with N-LD aged between 10 and 12 years participated in the study. The data were collected through clinical interviews. The data were analyzed by content analysis. Students' limited understanding of zero and operations affects their interpretation of arithmetic operations with zero. The conceptualizations of students with LD and N-LD regarding specifically division by zero show similarities with the exception of their use of the knowledge about operations. It has been observed that LD students have developed a different algorithm when it comes to addition and multiplication with zero. Through this study examining the differences in the understandings of students with LD and N-LD on a specific concept in terms of underlying conceptions, it is thought to provide an insight in terms of discovering LD and a more detailed recognition of these students' mathematics.

The purpose of this study was to review the perception of quality of education in students who take physical education and sports education in three different universities. Descriptive survey model was used in this study to reveal the current situation. The Six-Question Personal Information Form and also Scale of Quality of Education in Universities Providing Physical Education and Sports Education that was developed by Paktas were utilized to determine the demographic attributes of participants. It is observed at the end of the analyses that there is a significant relationship between perception of quality of education and gender; university and department (p<0,05). According to the results, considering the dimensions and subdimensions, the perception of quality of education in students in Bülent Ecevit University is higher compared to the same perception in other students from other universities.

Objectives: The COVID-19 pandemic caused people to suffer from secondary problems such as social isolation and loneliness as well as experiencing anxiety about catching and spreading the virus. Existing research emphasizes the roles of cognitive flexibility and hope for psychological adjustment but the mediating and moderating mechanisms have not yet been researched widely. Therefore, this study examined whether hope mediated the relationship between loneliness and psychological adjustment problems and whether cognitive flexibility moderated this mediation effect of hope in the relationship between loneliness and psychological adjustment problems during the COVID-19 pandemic curfew in Turkey. Methods: A total of 512 Turkish students and young adults completed UCLA Loneliness Scale, Brief Psychological Adjustment Scale, Dispositional Hope Scale, and Cognitive Flexibility Inventory for this cross-sectional study. Results: The results indicated that loneliness had a significant and positive predictive effect on the psychological adjustment problems and that this relationship was partially mediated by hope. Further, psychological flexibility moderated the relationship between loneliness and hope. Conclusions: The current study contributes a better understanding of the influence of loneliness on psychological adjustment, especially during the COVID-19 curfew period.

This research was designed with the aim of determining whether the self-confidence behaviors and leadership behaviors of students who are placed on the basis of YGS points and the aptitude tests of Kocaeli University differ in terms of various demographical characteristics and making suggestions on the basis of research. The research population consists of 2162 students who have been studying at the Faculty of Sports Sciences of Kocaeli University and the sample consists of 730 students who have voluntarily participated in the 2017-2018 academic year. The "Leadership Orientation Scale" which was developed by Bolman and Deal (1991) and adapted to Turkish by Dereli (2003) and the "Self-Confidence Scale" which was developed by Akin (2007) were used for data collection within the scope of this study. In the analysis of the data, the descriptive statistical test was used for examining the participants' personal information distributions and for determining whether the data were normally distributed or not. Manova, Tukey and Post-Hoc tests were used to determine the differences between the variables, correlation analysis was used to determine the relationship, frequency analysis were used to examine personal information distribution of the participants and regression analysis were used determine the effect while skewness-kurtosis values were evaluated in order to find whether the data exhibit a normal distribution or not. As a result of the analysis performed; it was found that there was a high positive correlation between the internal self-esteem and the subscales of the leadership scale of the School of Sport Sciences students (p<0,05). It was determined that the leadership orientations of female students are significantly higher than male students (p<0,05). In all dimensions, it was determined that the students who study at Physical Education and Sports Teaching Department had a significantly higher leadership orientation than the other departments (p <0,05). When the enrolling ways of the students were examined, it was found that the students who settled in the Faculty of Sports Sciences with aptitude test had significantly higher leadership orientations and self-confidence behaviors (p<0,05). When the self-confidence levels of the students who were placed in the faculty of Sports Sciences Faculties were compared by means of the aptitude test and YGS points, it was found that the self-confidence levels of the 1st and 2nd class sedentary students were lower than the 3rd and 4th class students (p <0,05). Although the self-confidence levels of the female students were higher than the male students, there was no significant difference between the self-confidence dimensions and the gender variable (p<0,05). It was determined that the students who enrolled to the Sports Sciences Faculty with aptitude tests show a high level of difference when they were compared to the students who enrolled to the Sports Sciences Faculty with YGS, by means of Leadership Orientations and the Self Confidence Levels.

It is quite difficult to adequately describe and evaluate the developmental processes of teachers without knowing and analyzing the pedagogical communities they participate in. Teachers acquire their own professional knowledge by carrying their experiences to the educational environment. Therefore, classroom microcultures experienced by teachers and teacher candidates are important for the formation and improvement of their professional knowledge. In this context, the quality of the classroom microcultures constituted by the teacher training programs come to the forefront. Within this context, in the present study, classroom microculture belonging to mathematics education course (Methods of Teaching Mathematics-II (MTM)) which has an important place in the teacher education was examined within the framework of the classroom norms. In other words, the classroom norms regulating the instructional planning activities performed by teacher candidates were investigated and the qualities of these norms were discussed. The data of the study were obtained through observing the learning environments of the MTM course in a mathematics teacher education program at a state university in Turkey. The data of the study, which is a case study, were analyzed through constant comparative analysis method. According to the findings of the study, it can be said that teacher candidates had difficulty in sustaining and participating the norms which are related to assessment-evaluation, teaching knowledge, specifying objectives and social language used.

Zero has been philosophically and symbolically interpreted differently from other numbers throughout history. While it is foundational to all mathematics, in early grades, it is denounced as representing "nothing." In this study, the understanding of zero among students with learning disabilities (LD) and no learning disabilities (NLD) were investigated, and conceptual similarities and differences were examined. This research is a multiple-case study based on qualitative design. The study participants were six students, three with LD and three with NLD, aged between 10 and 12 years. Data were collected through clinical interviews that focused on zero as a number, the meaning of zero as "nothing," zero as the cardinality of an empty set, and zero's use as a symbol (place value, placeholder, digit). According to the findings obtained through the content analysis method, no patterns demonstrated clear distinctions between students with LD and NLD in interpreting zero as a number or the meanings of cardinality. In other words, LD and NLD students had differences and similarities in their zero understandings but were not sharp enough patterns to identify the groups. The students' explanations of their conceptualizations of zero provided some notable results. Significant misconceptions within all students' understandings of zero suggest the need for primary school mathematics teachers to pay more attention to the meaningful understanding of zero.

Learning outcome (LO) literacy is conceptualized as a necessary skill for planning teaching and learning activities effectively. The skill has two main components: understanding and interpreting learning outcomes. The current study aimed to identify learning outcome literacy of elementary mathematics teachers with regard to this conceptualization. It is a case study based on the qualitative design. Participants were 5 mathematics teachers working at different elementary (5th-8th grade) schools in Turkey. Observations and semi-structured interviews were used for data collection based on 10 learning outcomes selected from algebra and number learning domains in local mathematics curriculum. Content analysis method was used for data analysis. According to the findings, LO literacy can be regarded as a basic teacher competence and it requires the teacher to use the knowledge and skills he/she has. The results showed that participant teachers' LO literacy was insufficient. Considering the interrelation among its components, LO literacy should be developed with all the sub-components for effective teaching of LOs.

The aim of this study was to investigate levels of satisfaction with leisure time in foreign students of Kocaeli University. In the collection of the data, the Leisure Satisfaction Scale (LSS) and demographic status questionnaire were used; 257 male and 103 female students participated. In the LSS scores for the separate domains, participants scored highest in Education and lowest in the Aesthetic subscale. There was no statistically significant difference in satisfaction levels between the genders, monthly income groups, and levels of academic achievement; but statistically significant differences were found between the students' faculties. Significant differences were found between faculties in the LSS scores on the Psychological subscale, and between students' monthly incomes and the Relaxation subscale on the LSS. As a result, there was a significant difference between the different faculties and students' satisfaction with leisure time on the Psychological subscale.

The aim of this study was to investigate the aggression levels of university students in different departments in terms of sport and other variables. The population of the study consists of university students studying at Kocaeli University; the sample group consists of a total of 700 students, 378 male and 322 female, studying in the Faculty of Sports Sciences, Faculty of Communication and Faculty of Education of Kocaeli University. A screening model was used in this survey. A Personal Information form developed by the investigator and a Turkish-adapted Buss-perry aggression scale was utilized to determine the aggressive attitudes of the individuals. The frequency distribution specified the demographic features and analyzed the data; the T-test examined the relationship between the two independent variables; ANOVA Variance was used to review the connections between more than one variable. Finally, the significance level is accepted as p<0.05. According to the findings of the research, there are statistically significant differences (p<0.05) in terms of gender, family structure, school department, family attitude, mother still living, sporting situation, kind of sport performed, reason for involvement in sport, cigarette-alcohol abuse and income level. We can state that sport positively affects the aggression levels of university students. Sport also varies by the gender variable, and males are more aggressive than females. It can also be pointed out that aggression varies by the school department, family attitude, cigarette-alcohol abuse, mother still living, reason for playing sport and income level.

The aim of this research is teaching addition with natural numbers and the concept of large and small natural numbers in the second grade mathematics course, through creative drama method. The study has been applied to 31 elementary school second grade students studying at a public school in the province of Aydin. In this research, case study based on observation method, which is one of the qualitative research methods, has been employed. The data have been collected through drama lesson plans, observation, and interview methods. The activities involving the acquisitions of ''adding two-digit natural numbers'' and ''absorbing large-small concepts'' prepared by the researcher, have been applied in the classroom. The drawings of students, literary notes, and observation reports kept by researchers have been used in the evaluation of the activity. As a result of this application, students' views towards the questions covering the whole application have been gathered. The results of the study suggest that prepared-planned creative drama activities are an entertaining and enjoyable way for students to learn. The notes taken by the participative observers and findings obtained from the interviews indicate that drama activities increase sharing among students and that the students could associate what they have learned with some of the situations they encounter in their every day-life. It is observed that the students learn by having more fun while playing games, which involves a high amount of physical movements. Drawing the attention of students through instructions in the warm-up phase of the activity increased students' curiosity in learning. In the animation phase of the activity, it was observed that the students' interest in the mathematics increased, they had fun while making the mathematical operations, their participation to the lesson was high throughout the activity, the energy they received from the lesson was at the maximum level, they learned by doing and living, and they obtained an experience they could use in their every day-life. In the evaluation phase of the activity, the students were asked to describe how they felt by drawing a picture or writing a story as a summary of the creative drama activity they experiences by doing. According to the stories they have written and the pictures they have drawn, it is apparent that they were entertained and happy throughout the activity. The results of this study indicate that the students relieve their mental exhaustion and a relaxed classroom setting is achieved through the relaxation activities.

Aims: Sentinel lymph node dissection is performed in endometrial cancer surgery instead of staging surgery, particularly when the disease is advanced and confined to the uterus. The aim of this study is to share our sentinel lymph node detection rates via the vaginal natural orifice transluminal endoscopic surgery method with the literature and to demonstrate a safer and more comfortable surgical treatment process. Methods: The analysis includes the patients who underwent surgery sentinel lymph node dissection for endometrial cancer utilizing indociyanin green in our center between January 2022 and June 2024. Results: In all, of 24 endometrial cancer patients underwent surgery sentinel lymph node dissection, nonendometrioid (serous) pathology was observed in only 1 (4%) patient, our other patients (96%) had endometrioid adenocarcinoma pathology. The rates of our sentinel lymph node dissection bilateral and symmetric are 96% (23/24), 94% (22/24), and 79% (19/24), respectively. We would like to emphasize that we successfully used vaginal natural orifice transluminal endoscopic surgery approach on four of our patients who were unsuitable for laparoscopic and robotic surgery due to pain scores of 2 at the 12th hour after surgery and low lung capacity. Conclusions: Vaginal natural orifice transluminal endoscopic surgery and sentinel lymph node dissection will be considered as surgical options in other gynecological cancers due to the comfort it brings to the patient in endometrial cancer.

This study, considering certain variables, aimed at determining the relationship between elementary school teachers' personality types and the strategies they used in the learning and instructional process. The study designed with the singular and relational survey model was carried out with 580 elementary school teachers and field teachers from the city of Eskisehir in Turkey. The data of the study obtained using three inventories: The MBTI Form G, Learning strategies inventory and Instructional strategies inventory. At the process of data analysis chi-square, individual samples t-test, and one-way ANOVA statistical test were used. Some of the results are as follows: Personality types of the number of teachers are grouped extraversion, sensing, thinking=feeling and judging; teachers use the interpretation and repetition strategies more than other learning strategies; learner-based instruction strategies preferred by teachers and they use the inquiry, project, problem solving, sample event and questioning strategies more than other process strategies. The results showed when the learning and instructional strategies used by teachers are taken into consideration with respect to their personality types; it could be stated that they favor intuiting and thinking while learning and favor intuiting, thinking and feeling while teaching.

Background: This study presents the case of non‐purulent encephalomyelitis associated with astrovirus infection in a sheep from Eastern Anatolia, Türkiye. Methods: A necropsy was performed on a sheep showing nervous signs. Afterwards, brain tissue samples were taken and examined with histopathological, immunohistochemical and molecular techniques. Results: Neuropathologic changes included neuronal degeneration, diffuse gliosis, multifocal perivascular cuffing, neuronophagy and neuronal necrosis in the cerebrum, the cerebellum and the cervical spinal cord. Aerobic and anaerobic bacterial culture, selective culture for Listeria monocytogenes, and PCR analysis for rabies virus, tick‐borne encephalitis virus, Türkiye encephalitis virus, small ruminant lentiviruses and border disease virus were negative. However, the presence of astrovirus RNA in cerebral, cerebellar and spinal cord samples was demonstrated by a pan‐astrovirus RT‐PCR. Immunohistochemical examinations revealed astrovirus antigens within the neuronal cytoplasm. High‐throughput sequencing techniques identified the causative agent as a member of the genotype species Mamastrovirus 13 but representing a distinct genetic lineage with similarity to ovine astrovirus 1 in the open‐reading frames (ORF)1ab region and muskox astrovirus in the ORF2 region. Conclusion: This report provides evidence that astroviruses are potentially encephalitis‐causing pathogens in ovine populations in Türkiye, featuring an astrovirus strain distinct from those previously identified in sheep.

Background: When fetal echocardiographic examination is performed by experienced people, the postnatal accuracy rate is highand has a positive effect on mortality and morbidity in newborns. In our study, we aimed to analyze the prenatal data and postnatal outcomes of the patients who underwent fetal echocardiography. Materials and Methods: The study was conducted with patients who underwent fetal echocardiography in our clinic between August 2020 and December 2021. The patients were grouped as high-risk and low-risk patients according to fetal echocardiography indications, and intergroup analysis was performed. Results: The study was conducted with a total of 365 patients. The mean age of the patients was 30.81±5.9 years, and the gestational week was calculated as 24.97±4.28 weeks. Patients, 14 (3.8%) were multiple pregnancies, 131 (35.9%) were primiparous. When compared with the p renatal d iagnoses o f t he patients whose postnatal echocardiography results could be reached, the prenatal diagnosis accuracy rate was found to be 95.6%. As The most common fetal echocardiography indication was suspicion of heart disease in fetal ultrasonography. Congenital heart disease was detected in fetal echocardiography i n 8 4 (23%) of the patients, the most common anomaly was ventricular septal defect. While 230 (63%) of the patients were in the high-risk group according to fetal echocardiography indication, 135 (37%) were in the low-risk group. In the analysis, a significant increase was found in high-risk patients compared to low-risk patients, especially in terms of important cardiac pathologies (p<0.001). Conclusions: Fetal echocardiography is highly diagnostic when performed by experienced people. It was concluded that fetal echocardiographic examination should be routinely performed in high-risk patients for fetal heart disease, and fetal echocardiography should be performed in low-risk patients if fetal ultrasonography is suspicious.

This study examines the impacts of adaptive and maladaptive perfectionism on the perceived task performance of employees and explores the moderating role of perceived organizational support (POS) in those relationships. By integrating the trait activation theory and the job demand-resources model (JD-R), we investigate whether POS as an organizational resource facilitates or constrains the effects of perfectionism traits on task performance. The data were gathered from 347 white-collar, full-time employees working in different sectors in Türkiye. The results of the moderated regression reveal only a significant interaction effect of POS with maladaptive perfectionism on task performance. In line with our predictions, when employees perceive higher levels of POS, the negative association between maladaptive perfectionism and task performance diminishes. However, the results did not support the interactive effects of adaptive perfectionism and POS on performance. The current study adds to a growing body of perfectionism literature and provides further support that POS plays a crucial role in mitigating the negative consequences of maladaptive perfectionism on employee task performance.

Menopausal status affects the prognoses and consequences of breast cancer. Therefore, this retrospective study aimed to reveal the molecular variation profile differences in breast cancer patients according to their menopausal status, with the hypothesis that the molecular variation profiles will be different at premenopausal and postmenopausal ages. Breast cancer patients (n = 254) who underwent molecular subtyping and QIAseq Human Breast Cancer NGS Panel screening between 2018 and 2022 were evaluated retrospectively. Their menopausal status was defined by age, and those aged 50 years and above were considered postmenopausal. Of the subjects, 58.66% (n = 149) were premenopausal and 41.34% (n = 105) were postmenopausal. The mean age at the time of diagnosis for all patients was 49.31 ± 11.19 years, with respective values of 42.11 ± 5.51 and 59.54 ± 9.01 years for the premenopausal and postmenopausal groups, respectively (p = 0.000). Among premenopausal patients, the percentages of patients in BCa subtypes (luminal A, luminal B-HER2(−), luminal B-HER2(+), HER2 positive, and triple-negative) were determined to be 34.90%, 8.05%, 26.17%, 10.74%, and 20.13%, respectively, while in the postmenopausal group, these values were 39.05%, 16.19%, 24.76%, 6.67%, and 13.33%, respectively (p > 0.05). Considering menopausal status, the distribution of hormone receptors in premenopausal patients was ER(+)/PgR(+) 63.76%, ER(−)/PgR(−) 23.49%, ER(+)/PgR(−) 10.74%, and ER(−)/PgR(+) 2.01%, respectively, while in postmenopausal women, this distribution was observed to be 74.29%, 23.81%, 1.90% and 0.00% in the same order (p = 0.008). The most frequently mutated gene was TP53 in 130 patients (51.18%), followed by PIK3CA in 85 patients (33.46%), BRCA2 and NF1 in 56 patients (22.05%), PTEN in 54 patients (21.26%), and ATR and CHEK2 in 53 patients (20.87%). TP53, PIK3CA, NF1, BRCA2, PTEN, and CHEK2 mutations were more frequently observed in premenopausal patients, while TP53, PIK3CA, BRCA2, BRCA1, and ATR mutations in postmenopausal patients. These findings contribute to a deeper understanding of the underlying causes of breast cancer with respect to menopausal status. This study is the first from Turkey that reflects the molecular subtyping and somatic mutation profiles of breast cancer patients according to menopausal status. [ABSTRACT FROM AUTHOR]

Background: Patients with chronic thromboembolic pulmonary hypertension (CTEPH) in countries with limited resources have, to date, been poorly represented in registries. Objective: This work assesses the epidemiology, diagnosis, hemodynamic and functional parameters, and treatment of CTEPH in Russia, Kazakhstan, Turkey, Lebanon, and Saudi Arabia. Methods: A prospective, cohort, phase IV, observational registry with 3-year follow-up (n = 212) in patients aged ≥ 18 years diagnosed with CTEPH was created. Clinical, hemodynamic, and functional parameters were obtained at an initial visit, follow-up visits, and a final visit at the end of 3 years' observation or end of follow-up. Data were recorded on electronic case report forms. Parameters evaluated included 6-minute walking distance (6MWD), use of pulmonary endarterectomy (PEA), balloon pulmonary angioplasty (BPA), pulmonary hypertension (PH)-targeted therapy, and survival. All statistical analyses were exploratory and descriptive, and were performed in the overall population. Results: The most common symptoms were typical of those expected for CTEPH. Almost 90% of patients underwent right heart catheterization at diagnosis or initial study visit. In total, 66 patients (31%) underwent PEA before the initial visit; 95 patients (45%) were considered operable, 115 (54%) were inoperable, and two (1%) had no operability data. Only 26 patients (12%) had been assessed for BPA at their initial visit. PH-targeted therapy was documented at diagnosis for 77 patients (36%), most commonly a phosphodiesterase type 5 inhibitor (23%). Use of PH-targeted therapy increased to 142 patients (67%) at the initial visit, remaining similar after 3 years. Use of riociguat increased from 6% of patients at diagnosis to 38% at 3 years. Between baseline and end of observation, results for patients with paired data showed an increase in 6MWD. Survival at the end of observation was 88%. Conclusions: These data highlight the current diagnosis and management of CTEPH in the participating countries. They show that early CTEPH diagnosis remains challenging, and use of off-label PH-targeted therapy is common. ClinicalTrials.gov: NCT02637050; registered December 2015. [ABSTRACT FROM AUTHOR]

Objectives: In this study, it was aimed to evaluate the landscape plants used in the design of hospital gardens in terms of toxicity. Background: Although plants have positive effects on humans, some plants can be toxic due to the compounds found in their bodies. The toxicity of plants is an issue that needs to be addressed in design, and it is important to investigate the toxic properties of plants in designs to be made in hospital gardens, which have a large user population and especially where people come to heal. Methods: Observation technique and document analysis were used in the study. Species were identified by taking samples from landscape plants in the gardens of state hospitals in Bursa. The distribution of the identified plant taxa according to toxic groups and their relations with each other were analyzed. Results: Taxa used in hospital gardens were mostly nontoxic (54.43%). It has been determined that there is a linear relationship between the number of taxa and toxic groups, and the increase in the number of taxa also increases the number of toxic taxa. Conclusion: It is seen that toxic plants are used in the design of hospital gardens, but they are included in toxic taxa. It will be an important approach to raise awareness by placing labels showing the toxicity status of taxa together with the collection of toxic taxa at points far from users. [ABSTRACT FROM AUTHOR]

For the past 100 years, Turkishwomen have had the opportunity to obtain an education and enter the labor force due to the democratic regime established in 1923. Despite some economic and social barriers, they have taken advantage of these opportunities and advanced in their careers to some extent. However, as with all women around the world, they face barriers in their career paths. This study aims to analyze the scientific research studies on the glass ceiling syndrome conducted in Türkiye to gain detailed insights into people's perception of the glass ceiling and capture their perspectives on the factors that contribute to it. This is a meta-synthesis study aimed at conducting a systematic review of selected qualitative studies and integrating their findings. A systematic search was conducted across local academic databases, namely, Dergipark and Tubitak Ulakbim-Equal. MAXQDA 2022 software was used to code and analyze the articles. The factors forming glass ceiling defined by the studies were renamed as 18 subthemes in total and classified under three themes: (1) personal factors, (2) sociocultural factors and (3) organizational factors. Although the role of motherhood and work life balance was found to be the most frequently referred factor, some current research revealed that not only women but also men experience this syndrome in Türkiye, despite the patriarchal culture of the country. The study's limitations are noted, and the implications and future research directions are discussed. [ABSTRACT FROM AUTHOR]

Purpose of presented study is to investigate the interest of Türkiye-based IT organizations in QM (quality management), ISO 9001 and other ISO MSSs (management system standards). Within the scope of this purpose, a study was conducted on organizations included in IT-500 lists. Corporate websites of IT organizations in categories of hardware, software and services were systematically examined. Methodologically, content analysis was applied in data analysis and corporate websites of IT organizations constituted the data source. Results and evaluations of study are presented separately on the basis of quality certificate, other certificates, quality policy and other policies, and when analyzed holistically, it has been revealed that large-scale service category organizations care more about QM and other MSSs. Right after service category, hardware category organizations take their place in the ranking. However, large-scale software organizations lag behind hardware and service organizations. Small-scale software organizations, which are ahead of other small-scale categories, reached same figures as large-scale software organizations. Analyzing corporate websites of IT organizations, presenting their interest in QM and other MSSs, addressing their policies, evaluating them on the basis of largescale and small-scale organizations in aforementioned categories indicate the importance and show the contribution of the study to the academic field.

The aim of this study was to evaluate the relation of maternal pain catastrophizing score with children who underwent circumcision postoperative pain. This prospective cohort study was performed between March 2022 and March 2023 at Samsun University, Turkey. Demographic characteristics of mothers and children, mothers' education level, presence of chronic pain, and Beck Depression Inventory scores were recorded preoperatively. Pain catastrophizing was assessed by applying the pain catastrophizing scale (PCS) to the mothers of children who experienced postoperative circumcision pain. The mothers were divided into low-pain catastrophizing (Group 1) and high-pain catastrophizing (Group 2) group. A total of 197 mothers and sons participated in the study, with 86 (43.6%) in Group 1 and 111 (56.4%) in Group 2. Significant differences were found between the two groups in terms of the mothers' PCS scores (p < 0.001), education levels (p = 0.004), chronic pain scores (p = 0.022), and Beck Depression Inventory scores (p < 0.001). Our findings showed that children with high pain catastrophizing mothers experience greater postoperative pain than those with low pain catastrophizing mothers. This may be attributable to a mother's specific cognitive style for coping with pain, which is associated with the child's responses to painful experiences. [ABSTRACT FROM AUTHOR]

Aim: To investigate whether severe acute respiratory syndrome coronavirus is involved in the etiology of acute pancreatitis. Material and Methods: This study was conducted in Çiğli Educational Hospital, Bakırçay Univesity. The study included 2060 patients with AP admitted to hospital between March, 2020 and August, 2023. The patients were assigned into 2 groups based on presence of COVID-19 infection. Ethiological factors for AP were determined in all patients. Results: Gallstone was the etiological factor in 614 patients (32.9%) who were COVID (-) but it was the etiological reason in only 19 patients (19%) in COVID (+) group. No etiology was identified in 217 (11.6%) of COVID (-) patients who were diagnosed as idiopathic pancreatitis. Idiopathic pancreatitis was diagnosed in 107 cases (54%) in COVID (+) group. There was significant difference presence of the diagnosis, which was made according to etiological factor, between groups. Conclusion: There was no definitive etiological link between COVID-19 and AP; however, the fact that same team diagnosed such a different idiopathic AP in the same hospital with same diagnostic facilities implies an etiological role for SARS-CoV-2 virus in AP.

Aim: Primary care physicians need to be aware of the types of traditional and complementary medicine (TCM) used by patients to be able to guide patients away from harmful approaches and to aim them toward useful or at least seeming benign approaches. This study aimed to determine the prevalence of the usage of TCM methods in Turkey and the level of knowledge and attitudes of applicants about these methods. Methods: The universe of this cross-sectional study consisted of individuals aged 18 and over who applied to the Family Health Centers and agreed to participate in the study in 12 provinces in different regions of Turkey between July and December 2016. The questionnaires were applied to the volunteer participants by the researchers using face-to-face interview techniques. The questionnaire had 25 questions. Results: 80.6% of the participants benefited from TCM, and 86.4% stated they believed in the effectiveness of TCM. Women, university graduates of college who had private insurance used TCM (respectively; p=0.031; p=0.004; p=0.000), and women (83.3%) found TCM more useful than men (p=0.005). The most frequent reason for using TCM was "heard that it was useful". Conclusion: The results of our study indicated that a large portion of Turkish primary care patients use TCM and recommend it to their relatives. Therefore, health policies and academic knowledge should be developed in this sense. [ABSTRACT FROM AUTHOR]

Astragalus L. is the largest flowering genus of the Fabaceae family and is represented by approximately 3000 species worldwide. This study aims to determine the anti-aging and anti-diabetes effects of Astragalus leporinus, A. distinctissimus, and A. schizopterus, three endemic species in Anatolia. The anti-aging effects against elastase and collagenase enzymes and the anti-diabetic effects against α-glucosidase and α-amylase enzymes were determined. Some triterpene contents were also determined by GC-MS. Ursolic acid (85.86 mg/g extract) and oleanolic acid (49.11 mg/g extract) were detected in the acetone extract of A. schizopterus species, and only (2.10 mg/g extract) oleanolic acid was detected in the ethanol extract. α-Amyrin (5.46 mg/g extract), oleanolic acid (6.09 mg/g extract), and ursolic acid (8.95 mg/g extract) were identified in the acetone extract of A. distinctissimus species. In terms of anti-aging, A. leporinus var. hirsutus ethanol extract has shown the highest activity in elastase and collagenase inhibition activity methods (inhibition %: 17.26±0.18 and 11.47±0.15, respectively), standard reference substances (oleanolic acid and epicatechin gallate, inhibition %: 43.80±0.76, 84.08±0.49, respectively). When it is evaluated in terms of anti-diabetic, it was determined that acetone extracts of A. schizopterus and A. distinctissimus species inhibited α-glucosidase at a higher level than acorbose, which was used as the standard reference substance, at all concentrations. In addition, it has also been observed that both acetone and ethanol extracts of the three species studied showed moderate inhibitory activity against the α-amylase enzyme. When the results obtained were evaluated, it is possible to state that A. schizopterus and A. distinctissimus species used as animal feed should be subjected to more detailed studies to be used for the pharmaceutical industry, as they are rich in oleanolic and ursolic acids and show anti-diabetic.

This meta-analysis was performed to determine the overall effectiveness of computer assisted instruction on students' academic achievement in science education from 2001 to 2007 in Turkey. The study reported the results of 65 effect sizes (ES) included in 52 studies. Grand mean for 65 ESs was found to be 1.12. This effect size can be interpreted as an average student's achievement moved from the 50th percentile to the 87th percentile in science learning when computer assisted instruction was used. In addition, two variables (grade level of subjects and instruction method of comparison group) had a statistically significant impact on the mean of ES. (Contains 1 figure and 2 tables.)

Weight is one of the basic concepts of physics. Its gravitational definition accommodates difficulties for students to understand the state of weightlessness. The aim of this study is to investigate the effect of materials based on 5E teaching model and related to weightlessness on science student teachers' learning. The sample of the study was 9 volunteer student teachers who were in their first grade in Science Teaching Program in Fatih Faculty of Education, Karadeniz Technical University. Both qualitative and quantitative data were gathered to find answers to the research questions. Findings revealed that all physics textbooks reviewed gave gravitational definition of weight. Also the concept of weightlessness hasn't been covered in high school and some university textbooks. It was determined that before the implementation student teachers had non-scientific explanations about weightlessness. The implementation of the 5E teaching model and materials developed are effective on learning the weightlessness. It is suggested that similar applications can also be used in other physics subjects or in other fields of science.

This study was designed to compare the effects of Team Assisted Individualization (TAI) and Student Teams-Achievement Divisions (STAD) on fourth grade students' academic achievement in and attitudes towards mathematics. Seven classes of a school were randomly selected for this experimental study. Two of these were given instruction through TAI; two through STAD, and the remaining three were treated as a control group. For the purpose of the data analysis regarding academic achievement, the 3X1 covariance analysis was used to compare the groups. As a result of this comparison, both the TAI and STAD methods were found to have positive effects (d = 1.003 for TAI and d = 0.40 for STAD) on students' academic achievement in mathematics. The pairwise comparisons showed that the TAI method had a more significant effect than the STAD method. The scores for the attitude towards mathematics were analyzed by using non-parametric statistics. As a result of this analysis, no significant difference was observed regarding students' attitudes towards mathematics.

The purpose of this study is to establish the level of opportunities given to prospective physics teachers by practice schools in order to demonstrate their skills they developed through teaching programs. This study has been carried out by employing case study approach. As the first step, the curricula of the teaching professional courses offered in numerous teacher education faculties are tabulated, using document analysis. Then, the expected behavioral skills for prospective teachers are listed in accordance with interviews with five professors at KTU. With the guidance of these data, to determine both the degree of opportunity and the level of success, the professional activities of eight prospective physics teachers in these schools are observed using an observation chart. Finally, semi-structured interviews are carried out to obtain ideas, expectations and comments of eight prospective teachers and tutors. The obtained observational data showed that student-teachers are not offered ample opportunity in practice schools to demonstrate their skill, to utilize laboratory and education technology, to prepare evaluation-material, and to create simple tool-equipments. (Contains 1 table.)

The study was carried out with 175 Turkish students by using drawings at different ages understanding of gene, DNA and chromosome concepts. Students from 8th, 9th, 11th grades and, science and biology student teachers were simply asked to draw the structure of gene, DNA and chromosome in a cell and also to give explanations about these three concepts. Differences in understanding between the age groups were found to be significant for the concepts of gene and DNA. None of the groups exhibit sound understanding and regardless of the age levels, students in all groups had alternative ideas about the three concepts investigated.

Hazelnut husk is one of the most abundant agricultural residue in Turkey. Valorization of this lignocellulosic biomass would provide a promoting alternative for economical production of pullulan. In this study, dried hazelnut husk hydrolysate was used directly as fermentation medium for pullulan production by a domestic strain of Aureobasidium pullulans. The aim of this work was the optimization of some fermentation medium parameters by central composite design using response surface methodology (RSM). The effects of (NH4)2SO4 concentration, the volume of concentrated H2SO4 and the amount of ground hazelnut husk on pullulan production were optimized by RSM. The optimum levels of the fermentation parameters defined as 7.2 gL−1, 2.5 mL and 20 g, respectively. The maximum pullulan and exopolysaccharide concentrations were determined as 74.39 and 75.95 gL−1, respectively in the optimum conditions. Specific growth rate of the strain was found as 0.097 h−1. FTIR spectral attributes confirmed the structure of pullulan. Thermal decomposition temperature of synthesized pullulan was found as 247.15 °C. This study showed that hazelnut husk was one of the novel substrate for production of the pullulan by A. pullulans AZ-6. No previous work was found to utilize dried hazelnut husk as fermentation medium for pullulan production by A. pullulans. [ABSTRACT FROM AUTHOR]

Since 2011, with the Syrian conflict, a sizeable portion of the Syrian Circassian diaspora have fled to Turkey. The experience of deportation due to the Syrian civil war exposed the community to the same trauma for the third time. However, as the refugees were forced to leave their country, they experienced different conditions than their Arab and Kurdish counterparts. Utilizing solidarity networks through their kinship relations, the Circassian diaspora appears to have avoided the hardships encountered by other refugee groups at least to some an extent. In the meantime, the diaspora developed new survival strategies in the face of general negative attitudes towards refugees and Syrians. The recent diasporic experience has been generally discussed with regards to issues of social class, ethnic affiliation, and distinction. Yet, the gendered dimension of the recent forced migration has been underestimated or neglected. This study aims to understand whether the women within the Circassian community who migrated from Syria to Turkey generated new forms of roles to meet the social demands of the new diasporic experience. The evidence discussed here is based on fieldwork that was conducted in 2019. One of the significant findings to be assessed in this study is the reinforcement of the patriarchy within the diaspora and the factors that facilitated this process. [ABSTRACT FROM AUTHOR]

Background: Pediatric allergic contact dermatitis (ACD) is increasingly prevalent. Patch testing is the gold‐standard diagnostic method. Aims: Our study aimed to identify common contact‐sensitizing allergens in Turkish children. Patients/Methods: We retrospectively analyzed the patch test results and characteristics of 191 pediatric patients [114 (59.7%) females, 77 (40.3%) males], who received the diagnosis of allergic contact dermatitis between 2015 and 2019. Results: The mean age of the patients was 12.2 years (range 4–18 years). Thirty‐six (18.8%) of the patients in the study group had positive patch test outcomes with 56 positive allergens. Girls had a significantly higher rate of total positive patch test results than boys (75%/25%; p = 0.003, p < 0.05). The most frequent four allergens were nickel sulfate (n = 20, 10.4%), cobalt chloride (n = 6, 3.14%), p‐phenylenediamine (n = 5, 2.61%), Methylchloroisothiazolinone/methylisothiazolinone (n = 5, 2.61%), respectively. Conclusions: In our study, we discovered that in addition to the frequently encountered metal allergens such as nickel and cobalt, p‐phenylenediamine and Methylchloroisothiazolinone/methylisothiazolinone sensitivities were frequent in the Turkish population. p‐phenylenediamine sensitization can cause serious systemic dermatitis during the lifetime of children. We suggest that in Turkey personal care and hygiene products containing Methylchloroisothiazolinone/methylisothiazolinone should be legally regulated. Since childhood contact dermatitis may have an impact on the quality of life by influencing family and social life, suspected allergens should be detected as early as possible.

Background: The pathogenic Clostridia cause neurotoxic, histotoxic and enterotoxic infections in humans and animals. Several Clostridium species have been associated with abomasitis in ruminants. The present study aimed to investigate the frequency, and the presence of virulence genes, of Clostridium perfringens, Paeniclostridium sordellii and Clostridium septicum in lambs and goat kids with hemorrhagic abomasitis. Results: A total of 38 abomasum samples, collected from lambs and goat kids of 1 week to 1 month of age in different farms located in eastern Turkey between 2021 and 2022, were evaluated by histopathology, culture and PCR. At necropsy, the abomasum of the animals was excessively filled with caseinized content and gas, and the abomasum mucosa was hemorrhagic in varying degrees. In histopathological evaluation, acute necrotizing hemorrhagic inflammation was noted in abomasum samples. The examination of swab samples by culture and PCR revealed that C. perfringens type A was the most frequently detected species (86.84%) either alone or in combination with other Clostridium species. P. sordellii, C. perfringens type F and C. septicum were also harboured in the samples, albeit at low rates. Beta2 toxin gene (cpb2) was found in three of C. perfringens type A positive samples. Conclusion: It was suggested that vaccination of pregnant animals with toxoid vaccines would be beneficial in terms of protecting newborn animals against Clostridial infections. This study investigated the presence of clostridial toxin genes in abomasal samples for the first time in Turkey. [ABSTRACT FROM AUTHOR]
