Gem quality andradite‐rich garnet (IUC‐1), obtained from the Miocene trachyte dome near Ankara city (Turkey), has been identified as a potential natural secondary reference material for U‐Pb dating. In this study, U‐Pb dating was performed in five different laboratories using isotope dilution TIMS and laser ablation ICP‐MS to determine the homogeneity of euhedral garnet crystals. The U‐Pb ID‐TIMS data for IUC‐1 yielded 207Pb/235U and 206Pb/238U ages of 20.9 ± 0.4 and 20.6 ± 0.8 Ma respectively, and these values are consistent with U‐Pb LA‐ICP‐MS analyses, in which different garnet crystals yielded ages of 20.8 ± 0.1, 20.7 ± 0.1, 20.7 ± 0.2 and 20.2 ± 0.1 Ma. An andradite (IUC‐2) from the Serçeören wollastonite skarn (Turkey) can be used as a secondary reference material provided detailed imaging of the crystals is undertaken. ID‐TIMS data yielded 207Pb/235U and 206Pb/238U ages of 20.4 ± 0.4 and 20.9 ± 1.0 Ma respectively, and yielded U‐Pb ages on different grains of 20.5 ± 0.1, 20.7 ± 1.0, 20.8 ± 1.7 and 20.9 ± 1.6 Ma. The assigned weighted mean age of IUC‐1 (20.4 ± 0.5 Ma, 2s) is proposed as a 2023 reference value. IUC‐1 garnet is expected to contribute significantly to rapidly developing garnet geochronology in the near future. [ABSTRACT FROM AUTHOR]

Objective: The massive increase in COVID-19 cases led to the implementation of nationwide lockdown in Turkey. While enforced lockdown is an effective strategy to abate the transmission of the virus, it causes significant lifestyle changes in every part of the community. This study aims to assess the changes in eating habits, sleeping behaviour and physical activity status of final-year medical students (interns) whose education was suspended during the pandemic. Design: In this cross-sectional epidemiological study, an online questionnaire was created. Interns were asked questions regarding socio-demographic status, eating habits, sleeping behaviour and physical activity status before and during COVID-19 pandemic. Changes in dietary habits and sleep quality were evaluated under the guidance of Turkey Dietary Guidelines, Determination of Nutritional Status Report, Turkey National Nutrition and Health Survey and Pittsburgh Sleep Quality Index. Setting: Hacettepe University Faculty of Medicine – Ankara, Turkey. Participants: Among 536 students, a total of 340 students (63·4 %) answered the questionnaire. Results: After the beginning of lockdown, an increase in BMI was observed in both female (P = 0·002) and male students (P = 0·013). Students having healthy dietary habits increased by 18·8 % and unhealthy dietary habits decreased by 3·2 % during lockdown (P < 0·001). Overall, 63·2 % of students reported a decrease in physical activity, and 33·6 % reported a reduction in sleep quality, whereas 38·6 % reported an improvement in sleep quality. There was no significant difference in sleep quality between genders (P = 0·075). Conclusions: This study indicated that medical school suspension and enforced lockdown led to significant changes in interns' eating behaviour, physical activity and sleeping habits.

Rapid population increase, inadequate supply of affordable land for residential purposes, and economic reality of low-income residents have been the most important reasons behind the squatter settlements all over the world. As a developing country, since 1950, Turkey has been trying to deal with illegal settlement and construction issues and by the year 2000, it took yet another turn with the concept of “urban regeneration” in the urban areas. Based on this concept, this article has introduced general characteristics of slum regeneration and implementation stages of a regeneration project have been compiled with current data. One of the different implementations has been selected between many other projects and analyzed from a legal and technical perspective. How the region that was in the world megaslum list in 2005 had been transformed into the habitable places was explained. Thanks to this implementation project that contains a special regeneration law for the first time in Turkey, a new lifestyle has been provided for the gecekondu owners, landownerhip problems have been resolved, and squatter settlements have been legalized. The project shows that if they are well planned and developed, including through integrated planning and management approaches, cities can promote economically, socially, and environmentally sustainable societies.

All mobile devices use similar methods for text entry, because of their limitations. One of these methods is handwriting recognition systems which has different applications in different devices. In this study, the effects of handedness were examined whether it has any effect on usability scores and handwriting speed on a Graffiti handwriting recognition system in Palm-OS. This study was carried out on 20 Middle East Technical University students who have no experience on Graffiti with the age range of 20-28. Ten of them named themselves as left-handed and ten of them named themselves as a right-handed. Data collected from these users with two user tests and one questionnaire. In the first user test, users supposed to write a given text on an A4 paper. In the second user test, they supposed to write given text to PDA (Personal Digital Assistant) via Graffiti handwriting recognition system. At the end, System Usability Scale (SAS) is used to see the usability of the Graffiti. By this way, writing speed, error rates, and usability of the system can be seen. In the paper based user test, left handed users significantly writes slower than right handed users. On the other hand, there is no significant difference between writing speed of left-handed and right-handed users. Also, there is no correlation between writing speed difference on this task. That means, being a fast writer on paper does not meant to be a fast writer on a handwriting recognition system because those two activities need different mental and motor skills.

In order for the intensive care nurses to recognize the ethical problems and to take proper decisions towards the solution of these problems, their moral sensibility, which is defined as the capability of distinguishing an ethical problem should be developed. In this study, it was aimed to investigate the moral sensibilities of intensive care nurses. Ninety out of 102 nurses who were working in the intensive care units of a teaching hospital in Ankara and accepted to be enrolled in the study constituted the study group in this definitive and sectional study. Data collection form is composed of 15 questions consisting of sociodemographic characteristics and study conditions. Moral sensibility of intensive care nurses in the study was in the moderate degree. The total moral sensibility score was not related with age, marital status, educational status, time exercised in intensive care, time exercised in profession, and taking any ethical courses before or after graduation, whereas age and time exercised in profession were closely related with some sub-dimensions of moral sensibility. In order to increase the level of moral sensibility of intensive care nurses and thus to recognize and solve ethical problems, it is suggested to plan postgraduate and continuous education programs. Furthermore it is necessary to conduct larger scale studies to determine different variables affecting the moral sensibility of intensive care nurses. [ABSTRACT FROM AUTHOR]

The purpose of the study is to investigate the effects of an applied environmental education project carried out using the green-class model on students' environmental knowledge and its retention. 101 7th grade students attending Nazim Akcan Primary School in the Altindag Province of Ankara participated in the study. The study was carried out in the form of pre-test post-test monitoring design. The Environmental Knowledge Test was used as a data collection instrument. For the analysis of the data, a two-way ANOVA for mixed measures was used. The post-test and monitoring test means of both the experimental groups were found to be significantly higher than the control group. As a conclusion, the green-class model considerably enhanced the environmental knowledge of the students and its retention. It was able to make a great contribution to the environmental knowledge of the students residing in a low socio-economic neighbourhood. This project is an original study and can be implemented with different samplings. [ABSTRACT FROM AUTHOR]

The article presents a study which investigated the frequency and possible reasons for academic procrastination among high school students in Ankara, Turkey. The study showed that academic procrastination is experienced by more than half of the participating students and has no gender prevalence. It found some of the contributing factors of academic procrastination include fear of failure, difficulty in making decisions and laziness.

Abstract: The objectives of this study were (1) to evaluate levels of lead (Pb) and cadmium (Cd) in the breast milk at 2months postpartum, (2) to investigate the relationship between Pb and Cd levels in breast milk and some sociodemographic parameters and (3) to detect whether these levels have any influence on the infant''s physical status or on postpartum depression in the mothers. Pb and Cd levels in breast milk were determined by Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). The median breast milk concentrations of Pb and Cd were 20.59 and 0.67μg/l, respectively. In 125 (87%) of 144 samples, Pb levels were higher than the limit in breast milk reported by the World Health Organization (WHO) (>5μg/l). Breast milk Cd levels were >1μg/l in 52 (36%) mothers. The mothers with a history of anemia at any time had higher breast milk Pb levels than those without a history of anemia (21.1 versus 17.9μg/l; p=0.0052). The median breast milk Cd levels in active and passive smokers during pregnancy were significantly higher than in non-smokers (0.89, 0.00μg/l, respectively; p=0.023). The breast milk Cd levels of the mothers who did not use iron and vitamin supplements for 2months postpartum were found to be higher than in those who did use the supplements (iron: 0.73, 0.00μg/l, p=0.023; vitamin: 0.78, 0.00μg/l, p=0.004, respectively). Breast milk Cd levels at the 2nd month were correlated negatively with the z scores of head circumference and the weight for age at birth (r=−0.257, p=0.041 and r=−0.251, p=0.026, respectively) in girls. We found no correlation between the breast milk Pb and Cd levels and the Edinburgh Postpartum Depression Scale scores. Breast milk monitoring programs should be conducted that have tested considerable numbers of women over time in view of the high levels of Pb in breast milk in this study. [Copyright &y& Elsevier]
