Objectives: This study investigated the challenges of young cross-cultural individuals (CCIs) through the cultural homelessness (CH) framework. Methods: Through a survey of 151 CCIs, the study empirically examined the relationship between CH and psychological well-being (PWB), as well as the moderating role of emotional clarity (EC). Results: Results indicated that CH was significantly and negatively associated with PWB, especially on the Positive Relations with Others and Environmental Mastery dimensions. Individuals with high CH tended to have less satisfactory relationships and a reduced sense of control over daily life situations, regardless of their EC level. A significant interaction effect between CH and EC was found, specifically in Positive Relations with Others (PR) and Personal Growth (PG). For individuals with high CH, however, satisfactory relationships were dependent on their EC level; they reported more positive relationships with others when their EC levels were high. Interestingly, individuals with high CH were likely to report a high desire for personal growth regardless of their EC level, indicating that they may appear ambitious but may be experiencing unclear emotions. Conclusions: These findings suggest that CH and EC are issues that need to be dealt with simultaneously. As individuals' PWB depends not only on their CH level, but also on their EC, reducing the level of CH should not be the only goal in promoting the well-being of CCIs. Increasing individuals' EC would be just as important, as high EC, along with low CH, predicts important dimensions of PWB.

Contingent self-esteem can be maintained by meeting the standards of social or introjected values. This study investigated whether social media-related contingent self-esteem was associated with depression in Instagram users; in a sample of 319 Instagram users, we examined the effect of contingent self-esteem on depression and the mediating effect of upward social comparison on this theorized relationship. The study findings indicated that higher contingent self-esteem predicted higher levels of depression for a week in Instagram users, which could be explained by the upward social comparisons made on this application, and showed that Instagram users with higher contingent self-esteem tended to compare themselves with other users they considered superior, thereby increasing their depression. This study provided evidence for the mechanism underlying the association between using social media and psychological well-being and indicated the vulnerability of contingent self-esteem within the social media context. Other implications and future research directions were also discussed.

SnO$_2$를 모물질로 하는 가스센서는 n형 산화물 반도체로서 공기중의 산소의 흡탈착 및 전자의 수수에 의해 전기전도도의 변화로 특정 가스를 감지한다. 지금까지 반도체식 가스센서의 모물질로 가장 많이 연구되어 왔지만 아직도 선택성, 안정성 등 여러 가지 문제를 안고 있다. 그리고 개선방안으로 귀금속 촉매의 첨가 및 입자의 크기의 조절 등이 흔히 연구되어 왔다. 따라서 본 연구에서는 순수한 SnO$_2$ 를 이용하여 소결 온도 및 입자 크기에 의한 영향을 CO가스 및 수분에 대한 감도, 반응 시간을 통해 알아보았다. 수열 합성 및 침전 법으로 나노 크기의 SnO$_2$ 분말을 합성하여 스크린 인쇄법으로 후막 가스센서를 제조하였다 침전법에서 SnCl$_4$에 암모니아수로 pH=10.5로 적정하여 SnO$_2$ 분말을 얻었다. 그리고 입자 크기를 조절하기 위해 수열 합성 시 autoclave 내의 수열처리 온도를 100, 150, 20$0^{\circ}C$로 조절하여 SnO$_2$ 분말을 제조하고 입자 크기와 성분분석을 위해 XRD, SEM, TEM, BET 측정을 하였다. 그 결과 침전법으로 제조한 입자의 크기는 20nm 정도였으며 수열 처리한 SnO$_2$ 입자는 10nm이하의 미세한 입자를 얻을 수 있었다. 수열 합성 시 온도가 높아질수록 더 작은 입자 크기를 얻을 수 있었고 600, 7()0, 80$0^{\circ}C$ 열처리 후 입자성장이 침전법에 의한 SnO$_2$ 분말보다 더 작게 일어났다. 이렇게 제조한 나노크기의 SnO$_2$ 분말을 이용하여 습도 및 CO 가스에 대한 그 특실을 평가하였다. CO 20ppm에 대하여 40%정도의 감도를 보였으며 입자가 작아질수록 높은 감도를 보이는 것을 확인 할 수 있었다. 반면 CO 가스와 반응 후 회복 시 입자 의기가 작아질수록 회복이 늦어짐을 알 수 있었다. 그리고 15$0^{\circ}C$에서 습도에 대한 반응 후 회복시간을 조사해보니 같은 결과를 얻을 수 있었다. 이것은 입자 필기가 작아질수록 많은 흡착 사이트를 제공함으로써 높은 감도를 가지지만 반면 다량의 흡착된 가스들이 탈착 하는데 더 많은 시간이 소요되었기 때문이다.

This paper investigates the relationships between leader-member exchange(LMX), perceived team efficacy, and organizational citizenship behavior(OCBI, OCBO) in the Korea Post. Also the study investigates the moderator effect of leader integrity and the mediator effect of perceived team efficacy in the relationships between LMX and OCB(OCBI, OCBO). The multiple regression analysis were employed to test the hypotheses. The main finding of this study was as follows: First, LMX had a positive effect on the perceived team efficacy. Second, the perceived team efficacy had a positive impact on OCB(OCBI, OCBO). Third, the perceived team efficacy completely mediated effect on the relationship between LMX and OCBI. Also the perceived team efficacy partially mediated effect on the relationship between LMX and OCBO. Fourth, the positive relationships between LMX and OCB(OCBI, OCBO) were stronger when leader integrity was high rather than low. In particular, this review concludes with implications for future research, limitations of this study, and practical application.
