In 1950s, the concept of brain death, which began to be discussed primarily in terms of medicine and then in terms of religion, law, and ethics, became a central topic in all world countries as it was an early diagnosis of death. Despite the fact that brain death (BD) diagnosis is of importance for benefitting from organ and tissue transplantation of patients in the world, the literature still involves no bibliometric studies that made a holistic evaluation of the publications about this issue. The present study aims to investigate the top-cited articles about BD published between 1980 and 2018, identify the citation collaboration of the journals, demonstrate the collaboration between the countries, define the relationship between organ transplantation and BD, and reveal the latest developments and trend topics about this issue. In addition, this study aims to investigate the relationship between religions of countries and brain death publication productivity. Documents for bibliometric analysis were downloaded from Web of Science. The literature search was performed using the keywords “brain death/dead” during 1980–2018. The correlations between gross domestic product (GDP), Human Development Index (HDI) and publication productivity of the countries on BD were investigated with Spearman’s correlation coefficient. There was a high-level, statistically significant correlation between the number of publications and GDP, and HDI and the number of publications about BD (r = 0.761, p < 0.001; r = 0.703, p < 0.001). The USA was the top country in terms of publication productivity, which was followed by developed countries such as Germany, Japan, France, and Spain. However, the contribution of the undeveloped or developing countries such as China, Brazil, Turkey, Iran, and South Africa was found to be considerably important. While many people in the world die with undamaged organs, many other people die needing those organs. Therefore, it is considered that the collaborations and thus multidisciplinary studies about BD should be increased in the world countries, and the countries should be involved in bigger collaborations instead of little clusters. Especially, Muslim countries should be encouraged to do research and publish studies about the issues of brain death and organ transplantation.

This study aims to investigate the relationship between individuals’ attitudes about acceptance of aesthetic surgery (e.g. rhinoplasty, autoplasty, blepharoplasty, and mammaplasty) and some of the worship practices in Islamic religion such as performing prayer, fasting, and going to pilgrimage. Although many people think that aesthetic surgery is inappropriate in Islamic religion, no studies in the literature were found to have investigated this issue. This study collected data through a questionnaire administered to 96 patients who applied to our Plastic Surgery Clinic and underwent various surgical operations and 96 patients who were recommended plastic surgery but rejected to have one; the questionnaire aimed to identify the participants’ frequency of religious worship practices and appropriateness of aesthetic surgery to their beliefs. The participants responded on the frequency of religious worship levels according to the options in the questionnaire. The “Acceptance of Cosmetic Surgery Scale” was utilized in order to identify their attitudes towards aesthetic surgery. Levels of performing prayers, fasting, and going to pilgrimage in the groups that accepted surgery and in the groups that rejected surgery were significantly different (p < 0.001, p = 0.008, p < 0.001). In two different groups, the Acceptance of Aesthetic Surgery Scale scores were significantly different within the prayer groups and fasting groups (p < 0.001, p < 0.001, p = 0.001, p < 0.001). While the group that accepted surgery indicated no significant differences between those who thought about going to pilgrimage and who did not (p = 0.650), there was a significant difference in the group that rejected surgery (p < 0.001). While 14.6% of the participants in the group that accepted surgery considered aesthetic surgery a sin, this proportion was 56.3% in the group that rejected surgery, and this difference was significant (p < 0.001). In both surgery groups, there were differences in the scale scores of those who considered aesthetic surgery a sin and those who did not (p < 0.001, p < 0.001). There was a significant relationship between worship practices, one of the biggest indicators of the level of belief in Islamic religion, and aesthetic surgery attitudes. However, despite the fact that belief levels affect the decision of having an operation in plastic surgery, in case of serious health problems, the decision of having an operation becomes more important religious beliefs.

Social networking sites (SNSs) enrol new subscribers each day. However, problematic SNS use has undesirable effects on psychological functioning. Therefore, it is important to identify the factors that contribute to the development of problematic SNS use. Very few studies have focused on revealing the underlying mechanisms of problematic SNS use. Although many past studies have examined the relationship between metacognitive beliefs and Internet addiction, the association between metacognitive beliefs and problematic SNS use has not been adequately explored. In this study, we aimed to explore the association between metacognitive beliefs and problematic SNS use among young adults. A total of 308 individuals participated in this study. A socio-demographic data form, the Metacognitions Questionnaire-30 (MCQ-30), and Social Media Addiction Scale (SMAS) were administered. Group comparisons were performed using multivariate analysis of covariance. Pearson's correlational and multiple linear regression analyses were conducted to examine the associations between metacognitive beliefs and problematic SNS use. The SNS addicts scored higher in all of the SMAS assessments. When compared to non-addicts, SNS addicts obtained higher scores on all the subtests of the SMAS and MCQ-30 except cognitive self-consciousness. The negative beliefs about the uncontrollability and danger of worry, cognitive confidence, and need for control thoughts were associated with SMAS mood modification, relapse and conflict subdimensions. Our findings revealed that dysfunctional metacognitive beliefs are related to problematic SNS use among young adults. These findings indicate that mental health workers should consider the modification of metacognitive beliefs in the treatment of problematic SNS use.  相似文献

Serum testosterone and cortisol levels were measured by radioimmunoassay in 14 young male judo competitors, in samples taken 10 minutes before and 45 minutes after two different procedures. The first involved physical exercise and the second competitive fighting. Both procedures were of 5 minutes duration and sessions took place at the same time (between 10:00 A.M. and 12:00 P.M. local time) but on different days. Comparing the two situations over all subjects revealed that testosterone increased after exercise and decreased slightly after Competition. Between subject comparisons suggested that contrary to previous claims, winning or losing did not significantly change the testosterone and cortisol levels. Comparisons of subjects who were members of the Regional Team with individuals who were not part of that group confirmed that members increased their testosterone levels after competition, whereas the nonmembers showed a significant decrease. Moreover, success of the individuals, in their sporting record, correlated positively and significantly with the changes of testosterone observed during the competition. These preliminary results suggest that previous personal experience of success can influence the pattern of the psychoendocrine response to a contest situation.  相似文献

The tree-based data structure of -tree for propositional formulas is introduced in an improved and optimised form. The -trees allow a compact representation for negation normal forms as well as for a number of reduction strategies in order to consider only those occurrences of literals which are relevant for the satisfiability of the input formula. These reduction strategies are divided into two subsets (meaning- and satisfiability-preserving transformations) and can be used to decrease the size of a negation normal form A at (at most) quadratic cost. The reduction strategies are aimed at decreasing the number of required branchings and, therefore, these strategies allow to limit the size of the search space for the SAT problem.  相似文献
