As a result of advances in science and technology, the importance of metal matrix composite materials is increasing gradually today. However, in many studies, composite production is carried out with monotype ceramic particle reinforcement. In this study, the production, microstructure-hardness, and wear performance of composite-hybrid materials that had AA 7075 aluminum powder metal matrix and were reinforced by SiC and Al2O3 ceramic particles at different ratios were examined. The prepared Matrix and reinforcement powder mixtures were mixed for half an hour in the three-axis Turbula T2F type mixer and then, pressed unidirectionally and cylindrically under the pressure of 700 MPa. The pressed samples were sintered for 1 h at a temperature of 600oC in the argon atmosphere. Microstructure examinations were carried out using SEM (Scanning Electron Microscope) and optical microscope devices, while hardness measurements were obtained as a result of Brinell measurement. Wear performance of the test samples were tested in the Pin-on-disk type device at 10 N load and 500 rpm rotation speed by depending on the wear distances at 1000, 1500 and 2000 m. It was observed that hardness increased as the amount of ceramic particle in composite-hybrid samples increased. As a result of wear tests, in hybrid composites, compared to single-phase ceramic particle reinforced composites, weight losses increased depending on the increase in the reinforcement amount.

Share of government expenditures in the GDPs are increasing virtually everywhere. Available data for developed countries indicate that the beginnings of this upward trend date back to the mid-19th century. Interestingly, economic growth rates did not increase significantly over time despite the increases in government expenditures. Low income countries today spend more than the double of what today’s developed economies were spending on average in 1900. However, this is not helping them to converge to richer economies. Why are government expenditures increasing then? This question might have global pertinence but due to the variety of country-specific factors, it can be best studied on a single country level. In this article, the country of focal interest is Turkey. Five important variables that might affect government expenditures from different angles are evaluated regarding their contributions to the out-of-sample predictions of government expenditures using random forest methodology. Military expenditures are estimated as primarily important for determining the government expenditures in Turkey in the last fifty years, while tax collections happened to be the second most important factor affecting the ups and downs of government expenditures around a time-varying average line. Per capita income, urbanization and inflation also affect government expenditures in various ways.

Follicle-stimulating hormone 10 IU was administered subcutaneously in 15 rats on 4 consecutive days, with OHSS induction on day 5 by 30 IU of human chorionic gonadotropin. Group 1 (n=5) comprised 35-day-old control rats, group 2 (n=5) 35-day-old OHSS rats, group 3 (n=5) 27-day-old OHSS rats receiving 1 mg/kg of oral tamoxifen for 7 days, group 4 (n=5) 27-day-old OHSS rats receiving 3 mg/kg of oral tamoxifen for 7 days. All rats were decapitated on day 35. Serum VEGF, endothelin 1, and ovarian follicular reserve were assessed in all rats. Kruskal–Wallis variance analysis and the Mann–Whitney U-test were used for statistical comparisons. A Bonferroni correction was performed to control the inflation of significance, with a significance level set at a P-value of less than 0.025.Results: Despite higher serum VEGF, endothelin 1, follicular reserve, and angiogenesis and fibrosis of the corpus luteum in the OHSS group compared to controls, these differences were not significant (P>0.025, Mann–Whitney U-test). There was a significant reduction in the ovarian follicular reserve in tamoxifen groups compared to controls (P0.025, Mann–Whitney U-test).Conclusion: Tamoxifen 1 g and 3 g resulted in a dose-dependent increase in VEGF and endothelin 1 levels, and ovarian follicle reserves were significantly reduced in our experimental model. Keywords: low-to-high doses of tamoxifen, OHSS, cystic enlargement of the ovaries, hCG

Education has an important role in humans’ behaviours. Undergraduate education has headed among factors that influence maturation period before vocational lifes of individuals. The purpose of this study is to determine whether attitudes of university students for handicapped individuals differ according to some variables. This study which was carried out in screening model was done with 1167 people including 646 females 521 males who maintain their education at faculties taking initial teacher training in 2016 spring term at Yuzuncu Yil University. As data collection tool, Attitude Scale for Being Educated of Handicapped Individuals and Personal Information Form, which was developed by Kosterilioglu [12], was used. As statistical method, Duncan’s multiple range test was used in determining different groups following one-wat analysis of variance. Among these variables, pearson coefficients of correlation were calculated separately in groups in determining relation. In determining relationship between groups and categorical variables , chi square test was used. In calculations, value of p was taken as 0,05 and SPSS statistic program was used for calculations. While point average of attitudes of male students , who maintain their educations at Yuzuncu Yil University, for handicapped people was ascertained as 54.27±23.54, point average of attitudes of female students was determined as 55.86±26.34. A significant difference between male and female students according to gender variable was not seen in attitudes for being educated of handicapped individuals (P>0,05). It was observed that attitudes for being educated of handicapped individuals in starting and end of undergraduate term were higher than intermediate classes (P

The purpose of the study is to determine factors, which lead physically handicapped badminton players in Turkey to tend towards badminton sport, and expectations of sporters. 45 (Male: 29 Female: 16) physically handicapped sporters, who participated in Turkey Bandminton Championship for Physically Handicapped, which was arranged in Antalya on 24-26 February, 2017, from different cities, attended the study voluntarily. Developed by Sunay and his colluages [13], tendency to sports and expectation survey was used in badminton branch after expert opinions, firstly, were received and necessary regulations were made for using it in our study. In order to determine whether the difference between opinions of sporters, attending the study, according to their genders, their ages, their best sport degrees, their sport years, their parents’ educational backgrounds and jobs, is important or not, one-way analysis of variance was used. To identify resource of the difference, Duncan’s multiple range test was used. Kruskal Wallis H test was used when normality and homogeneity of variances were not provided. Value of p for comparisons was taken as 0,05. Consequently, it was determined that, in Turkey, effects of environment, friend-peer group and trainer on sporters playing at elite level as physically handicapped are high in starting badminton firstly while effects of sport complex, parents and siblings, mass media such as television and media organs on tendency to badminton are quite low. It was ascertained that liking badminton sport and delighting in earning success were effective as the reasons of physically handicappeds’ playing badminton sport and their expectations were, firstly, to be chosen for national team and to be national team sporters.

Abstract Swallowed foreign bodies encounter a major problem especially in children, but fortunately they mostly do not cause any related complication and are easily passed with the stool. In this paper, an interesting journey of a needle is presented. A 20-year old female admitted to our emergency service after she had swallowed a sewing machine needle, which is initially observed in the stomach in the plain abdominal radiography. During the follow-up period, the needle traveled through bowels, and surprisingly was observed in the left lung on 10th day of the follow-up. It was removed with a thoracotomy and pneumotomy under the fluoroscopic guidance. The postoperative period was uneventful and the patient was discharged from the hospital on the day 5. We also review the literature on interesting extra-abdominal migrations of swallowing foreign bodies.

Background: Incentive spirometer is used in lung expansion therapy to maintain alveolar patency and improve pulmonary volumes in postoperative cardiac surgical patients. Deep breathing exercises with an incentive spirometer significantly reduce the development of postoperative pulmonary complications after open-heart cardiac surgery., Aim: To determine the effect of deep breathing exercises with an incentive spirometer initiated in the preoperative period on respiratory parameters and complications in patients who underwent open-heart surgery., Methods: This randomized controlled study was conducted with a total of 66 participants. The participants were randomized into a deep breathing group (n = 32) and a control group (n = 34). The control group received hospital routine physiotherapy, and the deep breathing group started to perform deep breathing exercises with an incentive spirometer in the preoperative period. Data were collected with the Sociodemographic and Medical Data Form and Patient Follow-up Form (respiratory rate, oxygen saturation (SpO 2 ) level, arterial blood gas parameters and posteroanterior chest X-ray were monitored with this form prepared by the investigators). The Medical Research Council Scale was used to determine the severity of dyspnea in the patients included in the study. Primary outcomes included respiratory rate, oxygen saturation, arterial blood gas parameters, posteroanterior chest X-ray, and evaluation of postoperative pulmonary complications development. Secondary outcomes included the mechanical ventilation time, length of intensive care unit stay, and length of hospital stay., Results: The incidence of postoperative pulmonary complications was 3.1% and 23.5% (p < 0.05) in the deep breathing and control groups, respectively. The mechanical ventilation time, length of hospital stay, and length of stay in the intensive care unit were significantly shorter in the deep breathing group (p < 0.05). In the deep breathing group, the mean SpO 2 values evaluated before surgery, on the first day in the Cardiovascular Surgery Unit, and on the day of discharge were significantly higher than the control group (p < 0.05)., Conclusion: Deep breathing exercises with an incentive spirometer initiated in the preoperative period contribute to a reduction in postoperative pulmonary complication rates, shortening of mechanical ventilation time, length of stay in the intensive care unit, length of hospital stay, and improvement of pre- and postoperative oxygenation., Trial Registration: The trial was registered on June 17, 2022, at https://www., Clinicaltrials: gov/ , registration number NCT05428722., Competing Interests: Declarations.

Objective: The aim of this study is to examine the intensive care experience of postoperative patients. Methods: This descriptive study was conducted between February and May 2021 with the participation of 75 surgical intensive care patients. Data were collected using the patient identification form and The Intensive Care Experiences Scale (ICES). Shapiro-Wilks test, Mann-Whitney U , Kruskal-Wallis H test, Bonferroni Corrected Mann-Whitney U test, and Spearman correlation analysis were used in analyzing the data. Results: The mean patient age was 62.8 ± 14.9 year (min: 23 and max: 95); 53.3% (n = 40) were male. The patients' mean length of stay in the intensive care unit was 1.4 ± 1.0 days. The mean ICES score of the patients was 57.4 ± 3.9. It was found that the patients' mean scores of the "satisfaction with care" subscale varied according to the surgical procedure applied, connection to mechanical ventilation, and status of seeing other individuals receiving treatment. Conclusions: Patients' intensive care experiences were partially positive. Being aware of the patients' experiences, supporting them in biopsychosocial aspects, and being in contact will contribute to the improvement of their postsurgical intensive care experience., Competing Interests: Declaration of Conflicting Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Aim: This study was carried out in order to examine whether there is a difference between the quality of life and motor skills of children with intellectual disability who participate in physical education activities and those who do not participate. Method: This study was conducted with a total of 34 children with 16 children in the control group (8 girls, 8 boys) and 18 children in the experimental group (11 boys, 7 girls) using a pre-test, post-test and control group experimental design. A 14-week "Physical Education Activities Program" was applied to the children in the experimental group. Children in the control group did not participate in physical education activities. The Bruininks Oseretsky test of motor proficiency second edition brief form 2010 to measure the motor performance and "Pediatric Quality of Life Inventory (PedsQL)" developed by Varni et al. in 1999 were used for children with intellectual disability. Findings: When the motor skill tests of the children with intellectual disability in the experimental group were evaluated, significant improvements were found in fine motor precision, fine motor integration, manual dexterity, bilateral coordination, balance, speed and agility, upper limb coordination, strength tests and all dimension scores for quality of life compared to the pre-test ( p  < 0.05). In the control group, a statistically significant improvement was observed in the quality of life Physical Functioning score and fine motor integration, bilateral coordination, and upper limb coordination tests ( p  < 0.05). More significant improvement was observed in motor skills and quality of life in children with intellectual disability who participated in the 14-week physical education program compared to the control group. Conclusion: Physical education activities contributed positively to improving the motor skills and quality of life of children with intellectual disability., Competing Interests: No potential conflict of interest was reported by the authors., (© The British Society of Developmental Disabilities 2021.)

Introduction: Acne vulgaris (AV) is a chronic, inflammatory disease of the pilosebaceous unit. Recently, three peptide-structured hormones, products of a single gene, have been discovered. These hormones are acylated ghrelin, des-acyl ghrelin and obestatin., Aim: To demonstrate the association of serum acylated ghrelin, des-acyl ghrelin, and obestatin levels with acne severity., Material and Methods: A total of 63 patients grouped as mild ( n = 22), moderate ( n = 21) and severe ( n = 20) acne according to the Global Acne Grading System and 20 medically healthy volunteers were included in the study. Serum ghrelin and obestatin levels obtained from the participants were examined., Results: When mean ghrelin, des-acyl-ghrelin and obestatin values of the acne-group (AG) were compared with the control group (CG), they were found be lower in the AG, but were not statistically significant. Among the patient groups, while acylated ghrelin values were highest in the severe AG, des-acyl ghrelin values were highest in mild severe AG and mean obestatin values were highest in moderate severe AG ( p > 0.05). When the groups were compared for obestatin values; the highest average value was detected in the CG. However, it was not significant when the groups were compared., Conclusions: It has been suggested that there may be a link between acne and the levels of acylated ghrelin, des-acyl ghrelin and obestatin which are decreased in the serum of acne patients. Because of the decrease observed in the levels of these hormones which have antimicrobial features, we suggest that inflammation in acne cannot be suppressed and the reproduction of the microorganisms that play a role in the aetiology of the disease cannot be prevented. The replacement of these hormones at physiologic concentrations may contribute to the acne treatment., Competing Interests: The authors declare no conflict of interest., (Copyright: © 2019 Termedia Sp. z o. o.)

Objectives: This study sought to evaluate pain severity and pain management methods of patients with carpal tunnel syndrome., Methods: This descriptive study was conducted with patients who were diagnosed with carpal tunnel syndrome (n=99) in the neurology clinic of the university hospital between August 2014 and December 2015. Patient data form, visual analog scale (VAS) and a pain management inventory were used to collect data., Results: Of the total, 64.6% of the patients experienced pain. Patients used prescription medication, massage, and exercise to control pain, and reported that the most useful method was exercise, followed by massage and, finally, prescription medication., Conclusion: Healthcare professionals may share the findings of relative benefit according to method of pain management and encourage patients to use non-pharmacological methods.

The aims of this study are to evaluate whether or not there is a relationship between mastalgia with anxiety and depression in young women with mastalgia who do not have organic breast pathology and to examine the effect of pain on the quality of life. Forty female pre-menopausal patients between the ages of 20-40 years with mastalgia and 40 totally healthy volunteers with the same characteristics were investigated with the Short Form 36 (SF-36), Hamilton Depression Scale, and the Hamilton Anxiety Rating Scale prospectively following breast examination and radiological examination. Statistical assessments were performed using the SPSS 11.5. Anxiety levels were observed to be higher in the patient group (p = 0.04). The depression level was higher in the patient group; however, this was not statistically significant (p = 0.08). The quality of life of the mastalgia group was determined to be lower than that of the control group, and the sub-parameters of physical function (p = 0.04), body pain (p = 0.02), general health (p = 0.03), and energy (p = 0.008) were found to be significantly low. There may be a relationship between mastalgia and depression in young women with mastalgia; however, a closer relationship between anxiety and mastalgia is observed. Mastalgia affects the quality of life of an individual negatively at a significant degree.

Purpose: Colonic pseudo obstruction disease commonly seen in the elderly, immobile patient group can cause serious mortality and morbidity. Our objective in this retrospective study is to share our clinical experience by evaluating patients with Ogilvie syndrome who were followed and treated in our clinic., Methods: Eleven cases with the diagnosis of Ogilvie syndrome followed up and treated between September 2010 and April 2013 were evaluated retrospectively. All the patients that had no symptoms of acute abdominal pain were initiated conservative treatment. Colonoscopic decompression was attempted for patients whose clinical pictures were not recovered. Patients underwent operation if they developed peritoneal irritation symptoms during these procedures and of their number of white blood cells seriously increased during the follow-up period., Results: A total of 11 patients were treated for Ogilvie syndrome. 6 of the patients underwent surgical treatment, and 5 were treated medically. Mortality developed in two patients. The main cause of mortality was a delay in diagnosis and additional severe underlying diseases. Seven patients were given Neostigmine. Of these, 2 patients required surgery and 3 patients responded to Neostigmine., Conclusion: Ogilvie syndrome is a rare cause of ileus of the colon. It is more common particularly in old patients with additional problems. If the disease is suspected and diagnosed early, unnecessary surgical interventions can be prevented with medical treatment choices.

Objective: Mastalgia is the most common complaint of patients who are admitted for breast examination. Breast pain may originate breast tissue pathologies or non-breast pathologies adjacent organs. One of the causes of mastalgia is the varicella-zoster infection of the thoracic nerve ganglions. The zona zoster infection is painful, and vesicular lesions in the infected dermatomal regions can be observed because of the reactivation of the latent varicella (Herpes)-zoster virus (VZV) in the dorsal radix of medulla spinalis. There are no reviews of the zona cases of mastalgia patients in the literature. We aimed to investigate and represent the characteristics of these patients., Materials and Methods: Patients complaining of mastalgia and who were diagnosed with zona zoster infection after physical examination and clinical evaluation in the outpatients department of General Surgery were investigated retrospectively between January 2010 and January 2015., Results: The study included 12 patients. All of them were female, and the mean age of patients was 51.66 (36-72) years. Eight of the zona cases were seen in the right breast (66.6%), and four of them were seen in the left breast (33.4%). Complaints of patients were pain (100%), eruption (70%), and burning sensation (60%). Underlying pathology was seen in one of the cases. Physical examination at admission revealed that four of the patients did not have any physical abnormality (33.3%). On the contrary of vesicular lesions, typical physical findings of zona, were seen in eight patients (66.7%)., Conclusion: Detailed history analysis and physical examination of the breast should be performed, particularly in older patients with unilateral severe mastalgia, and zona should be considered., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Objective: The aim of the study is to report our experience with fibrin glue application in the management of bleeding from the gallbladder bed during laparoscopic cholecystectomy, which could not be controlled by conventional methods., Material and Methods: Three hundred eighty-two patients underwent laparoscopic cholecystectomy. Fourteen patients with bleeding from the gallbladder bed, which could not be controlled by conventional methods, were analyzed retrospectively., Results: Fibrin glue was used in 10 patients. Six (71%) were female and 4 were (29%) male. The mean age was 55.7 years. Fourteen patients were operated for the presence of symptomatic gallstones. Thirteen patients (92%) had a concomitant pathology. The mean time spent to maintain hemostasis was 23.9 minutes (15-35). Blood products were used in two patients with hemoglobin values under 8 mg/dL. Hemostasis could not be achieved in a patient despite fibrin glue application, and the operation was converted to open surgery., Conclusion: The application of fibrin glue for bleeding from the gallbladder bed during laparoscopic cholecystectomy can reduce conversion rates, further studies including more patients are required.
