This article explores the relationship between the gender composition of scientific research teams and scientists' individual performance. The gender composition of research teams is an important feature of workplace settings and influences the way people interact and communicate; however, previous research has not directly examined its relationship with scientists' individual performance. Drawing on data collected on university faculties in China in 2016, this article tests several hypotheses about individual's performance in teams with different gender compositions. The results show that team gender composition has a clear gendered effect on scientists' individual performance. The effects of tokenism for women in men-majority teams is proven, but men in women-majority teams appear to be unaffected by tokenism. Moreover, the theories claiming that homogenous teams are more conducive to better individual performance than mixed teams are supported for men but not for women. The findings of this research suggest that recruiting more women into the scientific workforce may improve their performance and thereby help diminish the gender gap in performance. It also indicates that the Chinese preferential policies towards women in science formulated in recent years have had positive impacts. However, considering that more than half of the researchers in the survey are working in men-majority teams, the task of narrowing the gender gap in performance remains a challenge. Further work is needed to explore the tensions and benefits of working with the opposite gender.

최근까지 소득수준의 결정에 관한 노동시장 연구는 노동자의 속성 또는 직업의 특 성에 관심을 기울이며 진행되어 지리적 관점의 노동시장 운용에 관한 관심이 미비하였다. 본 연구는 지역노동시장을 실질적인 노동시장 개념으로 설정, 노동력 공급 측면의 특성을 강조하는 인적자본론과 수요측면의 특성을 강조하는 노동시장분절론을 지역적으로 특성화되 어 나타나는 지리적 관점으로 포괄하고, 개인의 소득수준을 개인의 속성과 차별화된 대도시 노동시장의 특성으로부터 영향을 받음을 실증적 분석을 통하여 고찰하였다. 분석에 나타난 개인의 소득수준은 개인의 속성에 의해 영향을 받지만 그 영향은 분절된 노동시장의 대도시 지역간 차별화 단면에 따라 변화함을 보여주고 있다. 이 연구는 기존의 두 주요 노동시장 연구 관점의 절충적 이해를 개인의 소득수준 결정을 통하여 실험적으로 시도하고 실질적 노 동시장의 운용으로 지역노동시장의 중요성을 강조하고 있다.

This study has two research objectives related to end-user computing (EUC). One of the research objectives was to investigate the current status of EUC of Korean firms. Another research objective was to examine the relationship between individual differences of end-users and EUC success. Using survey data from 752 end-users of 23 firms, the current status of EUC and the relationship between individual differences of end-users and EUC success were investigated. The current status of EUC was examined from six perspectives : 1) what is the characteristics of EUC strategy of Korean firms, 2) what are the individual characteristics of end-users in Korean firms 3) what are the characteristics of tasks performed by end-users computer, 4) what are the application areas of EUC, 5) How end-users are satisfied with the support of firm, 6) what are system usage and satisfaction of end-users. It was also found that individual differences of end-users are related to EUC success. More specifically, it was shown that the male gender, younger age, higher level of education, higher rank and organizational tenure, higher math ability, thinking type of cognitive style, positive and optimistic attitudes toward computer, more experience with computer, more computer education and knowledge are individual differences variables associated with EUC success. The results of stepwise regression analysis suggested that the individual difference variables accounted for 14%, 25%, 39%, and 30% of the variances of four EUC success variables, satisfaction for outcome, satisfaction for ability, frequency of computer use, and the number of tasks, respectively. Theses empirical findings suggest that EUC managers should consider individual differences of end-users in managing EUC, such as education, training support, and human resource management, to maximize potential benefits of EUC.

Organizational culture among flight crews has a profound impact on the individual attitude and behavior of member flight crews, and active training is conducted focusing on improving flight crews' Crew Resource Management(CRM) performance. However, adequate research and training on the relationships between flight crew's individual culture and CRM performance have not been conducted. Hence, this study examined the effect of individual cultural values on CRM performance and the moderation effect of psychological safety, with captains and first officers working for commercial airlines as participants. For the factors related to individual cultural value scale, power distance had no significant effect on CRM performance, uncertainty avoidance had a significant negative effect, and individualism had a significant positive effect. With regard to the moderation effect of psychological safety on the relationships between individual cultural values and CRM performance, a significant interaction was found between power distance and CRM performance, but not between uncertainty avoidance and CRM performance, or between individualism and CRM performance. Power distance and CRM performance exhibited a strong negative correlation in case of low psychological safety. Compared to existing research measuring the cultural characteristics of pilot groups on a national or organizational culture level, this study is uniquely valuable in that it also covers the relationship between individual cultural values of commercial airline flight crews and CRM performance.

Background: This study is aimed to verify individual and regional-level factors affecting the depression of Koreans and to develop social programs for improving the depressive status. Methods: This study used individual-level variables from the Korean Community Health Survey (2018) and used the e-regional index of the Korean Statistical Information Service as the regional-level variable. A multi-level logistic regression was executed to identify individual and regional-level variables that were expected to affect the extent of depressive symptoms and to draw the receiver operating characteristic curve to compare the volume of impact between variables from both levels. Results: The results of the multi-level logistic regression analysis in regards to individual-level factors showed that older age, female gender, a lower income level, a lower education level, not having a spouse, the practice of walking, the consumption of breakfast higher levels of stress, and having high blood pressure or diabetes were associated with a greater increase in depressive symptoms. In terms of regional factors, areas with fewer cultural facilities and fewer car registration had higher levels of depressive symptoms. The comparison of area under the curve showed that individual factors had a greater influence than regional factors. Conclusion: This study showed that while both, individual and regional-level factors affect depression, the influence of the latter was relatively weaker as compared to the first. In this sense, it is necessary to develop programs focused on the individual, such as social prescribing at the local or community-level, rather than the city and nation-level approach that are currently prevalent.

Accurate reproduction of intraoral tissue is essential in the fabrication of fixed prosthesis. This selection of impression material and method is very important. In this study, vinyl polysiloxane type impression material $Panasil^{(R)}$ was used. Three impression methods ; one-step technique, individual tray technique, and individual tooth tray technique using the vinyl polysiloxane type bite registration material $Futar^{(R)}$ Occlusion, were used to take horizontal and vertical impression. Improved stone models were fabricated. The amount of occlusal surface discrepaneies, interabutment distance discrepancies, amount of marginal defect were evaluated with the $X-PLAN360d^{(R)}$ and photoscanning. The results were as follows. 1. There was no significant difference in occlusal surface according to the directions and techniques of impression taking. 2. There was no significant difference in interabutment distance discrepancies according to the directions and techniques of impression taking 3. There was no significant difference in marginal discrepancies according to the direction of impression taking but there was significant difference between one-step technique and individual tray technique, individual tooth tray technique (P<0.05). Taken together, these results suggest that individual tray technique and individual tooth tray technique are more accurate for impression taking than one-step technique.

Objectives: Our aim was to answer the following questions: (1) Can mental health variance be partitioned to individual and higher levels (e.g., neighborhood and district); (2) How much (as a percentage) do individual-level determinants explain the variability of mental health at the individual-level; and (3) How much do determinants at the neighborhood- or district-level explain the variability of mental health at the neighborhood- or district-level? Methods: We used raw data from the second round of the Urban Health Equity Assessment and Response Tool in Tehran (in 2012-2013, n=34 700 samples nested in 368 neighborhoods nested in 22 districts) and the results of the official report of Tehran's Center of Studies and Planning (in 2012-2013, n=22 districts). Multilevel linear regression models were used to answer the study questions. Results: Approximately 40% of Tehran residents provided responses suggestive of having mental health disorders (30-52%). According to estimates of residual variance, 7% of mental health variance was determined to be at the neighborhood-level and 93% at the individual-level. Approximately 21% of mental health variance at the individual-level and 49% of the remaining mental health variance at the neighborhood-level were determined by determinants at the individual-level and neighborhood-level, respectively. Conclusions: If we want to make the most effective decisions about the determinants of mental health, in addition to considering the therapeutic perspective, we should have a systemic or contextual view of the determinants of mental health.

본 연구는 복합적인 사회 현상을 설명할 수 있는 장애학의 다중 패러다임을 통해 우리나라 장애인복지의 기본이라 할 수 있는 장애인복지법을 살펴보아, 한국 장애인복지의 성격을 규명하고자 하는 것이다. 연구결과 우리나라 장애인복지는 신체기능의 정상을 도모하는 입장에서 출발하여 보충적 복지를 강조하는 입장이 우세해 지고 있으며, 장애인을 억압하고 차별하는 사회 구조의 개선을 도모하는 입장도 나타나고 있다. 또한 하나의 패러다임이 우세하기보다는 다양한 패러다임이 나타나고 있으며, 장애를 사회 구조적인 문제로 보고 이의 해결을 위해 장애인에 대한 차별, 억압을 제거하고자 하는 노력이 있기는 하나, 실천적인 조치에서는 보충적 복지에 의존하는 입장, 개별적인 신체 기능의 향상을 통해 장애를 극복하고자 하는 입장이 주를 이루고 있다.
