UV molding is a process for integrating micro/nano polymeric optical components on optoelectronic modules. In the present study, a microlens array for vertical cavity surface emitting laser(VCSEL) to fiber coupling was designed, integrated and tested. At the design stage, design variables ware optimized to maximize the coupling efficiency, and tolerance analysis was carried out. At the integration stage, the UV transparent mold was fabricated and the microlens array on VCSEL array was integrated by UV molding process. Finally the coupling efficiency of VCSEL to fiber was measured and analyzed.

본 연구는 간호대학생의 시험불안이 우울과 삶의 질에 미치는 영향을 검증하는 것이 목적이다. 경북지역 K 대학교의 간호대학생을 대상으로 시험불안, 우울, 삶의 질에 대한 설문을 실시하여 160부를 분석하였다. SPSS 프로그램을 사용하여 상관분석과 단계적 회귀분석을 실시하여 확인하였다. 분석결과는 다음과 같다. 첫째, 시험불안과 우울은 양의 상관관계, 시험불안과 삶의 질은 음의 상관관계를 가진다. 둘째, 간호대학생의 우울과 삶의 질에 미치는 요인은 시험불안의 하부요인인 정서적 요인과 신체적 정신건강, 정신적 정신건강, 전공 만족이다. 즉 정서적, 정신적 건강이 나쁠수록 우울이 높아지고, 전공 만족이 낮을수록, 신체적 건강이 나쁠수록, 정신적 건강이 나쁠수록 삶의 질이 낮아지는 것을 알 수 있었다. 본 연구결과의 의의는 향후 간호대학생의 우울 증상을 감소시키고 긍정적인 정신건강과 삶의 질을개선하기 위한 정신건강 증진 전락과 교육적 중재 마련 기초자료를 제공하는 데 있다. The purpose of this study is to determine the impact of test anxiety on depression and quality of life in adopted of nursing college students. The 160 copies were analyzed by conducting a survey on test anxiety, depression, and quality of life for nursing students at K university. Correlation analysis and stepwise regression analysis were conducted to confirm. First, test anxiety and depression have a positive correlation, and test anxiety and quality of life have a negative correlation. Second, the factors affecting the depression and quality of life of nursing students are emotional factors, physical mental health, mental health, and major satisfaction, which are sub-factors of test anxiety. The significance of this study is to provide basic data for mental health promotion and educational intervention preparation to reduce depressive symptoms and improve positive mental health and quality of life in nursing students in the future.
간호대학생의 외모 만족도와 우울 관계에서 자아존중감 및 스트레스의 매개효과
한정원(Jeongwon Han) 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.21
목적 본 연구는 간호대학생의 외모 만족도, 우울, 자아존중감 및 스트레스 간의 관계를 살펴보고, 외모 만족도와 우울의 관계에서 자아존중감 및 스트레스의 매개효과를 검증하는데 목적이 있다. 방법 본 연구는 G시 소재의 일개대학 간호학과에 재학 중인 1학년에서 4학년 학생 179명을 대상으로 설문조사를 실시하였다. 자료분석은 대상자의 일반적 특성, 외모 만족도, 우울, 자아존중감, 스트레스는 t-test, One-way ANOVA, 피어슨 상관관계, SPSS PROCESS Macro 모델 6를 활용하여 매개효과를 분석하였다. 결과 연구결과 간호대학생의 외모 만족도, 우울, 자아존중감 및 스트레스의 상관관계에서 외모 만족도와 우울과 스트레스는 역 상관관계, 자아존중감은 외모만족도와 순 상관관계를 나타냈다. 간호대학생의 외모 만족도와 우울의 관계에서 자아존중감과 스트레스의 매개효과를 분석한 결과, 스트레스는 완전매개효과를 나타냈었으나, 자아존중감은 매개효과가 없었다. 외모 만족도과 우울의 관계에서 자아존중감과 스트레스의 이중매개효과 검증 결과, 외모 만족도외모 만족도와 우울 관계에서 자아존중감과 스트레스는 이중매개효과가 없는 것으로 나타났다. 결론 간호대학생이 인지하고 있는 우울을 감소시키기 위해서 자신의 외모에 대한 긍정적인 신체상을 갖도록 하는 내용과 간호대학생의 우울을 심리적으로 감소시킬 수 있는 다양한 프로그램을 통한 중재방안을 모색해야 할 것이다. Objectives The purpose of this study is to examine the relationship between appearance satisfaction, depression, self-esteem, and stress of nursing college students, and to verify the mediating effect of self-esteem and stress in the relationship between appearance satisfaction and depression. Methods The purposes of this study were to a survey of 179 first- to fourth-grade students enrolled in the nursing department of one university in G City. Data analysis analyzed the mediating effect using the subjects' general characteristics, appearance satisfaction, depression, self-esteem, and stress, t-test, one-way ANOVA, Pearson correlation, and SPSS PROCESS macro model 6. Results As a result of the study, in the correlation between appearance satisfaction, depression, self-esteem, and stress of nursing college students, appearance satisfaction and depression and stress showed an inverse correlation, and self-esteem showed a net correlation with appearance satisfaction. As a result of analyzing the mediating effect of self-esteem and stress in the relationship between appearance satisfaction and depression of nursing college students, stress showed a complete mediating effect, but self-esteem had no mediating effect. As a result of verifying the double mediating effect of self-esteem and stress in the relationship between appearance satisfaction and depression, it was found that self-esteem and stress had no double mediating effect in the relationship between appearance satisfaction and depression. Conclusions In order to reduce the depression perceived by nursing students, it is necessary to find an intervention method through various programs that can reduce the depression of nursing students psychologically and content to have a positive physical image of their appearance.

Purpose: The purpose of this study was to investigate the casual relationship between nurses’ social capital and turnover intention and to verify the goodness of fit between a hypothetical model and actual data in order to suggest the best model. Methods: This survey was conducted with 315 nurses working in general hospitals in Seoul. Data were collected from December 1 to December 30, 2011, and analyzed using SPSS Windows 18.0 and AMOS 16.0. Results: Nurses’ social capital was found to have a direct effect on reducting organization cynicism and increasing organizational commitment. Nurses’ organizational cynicism and organizational commitment were found to have a direct effect on turnover intention, but social capital did not have a direct effect on turnover intention. However, social capital had a partial and indirect effect on turnover intention through mediating organizational cynicism and organizational commitment. Conclusion: Results of this study indicate that nurse managers should put increased effort in reducing nurses’ organizational cynicism and improving their organizational commitment, two contrary parameters. At the same time managers need to develop plans to establish social capital more efficiently so that nurses have lower turnover intention.

Although Korea and China belong to the same Asian cultural sphere, they have formed their living cultures based on their different political, economic, human, and social characteristics. Although the cultures are similar, the spatial and physical characteristics embodied in the living spaces of the two countries are different according to the differences in the main living cultures. Most of the apartment-related studies in Korea and China are currently focused on the studies related to the spatial characteristics and plan composition of apartments. The balcony space in Korea and China is under-researched. In this regard, the purpose of this study is to analyze the differences in the development of balcony space in Korea and China through a literature survey of the spatial and physical characteristics of balcony space in Korea and China in the light of the changing environment of the times.
