Objectives : The purpose of this study was to examine the mediation effects of self-efficacy on the relationship between life stress and depression in university students to provide a basis for planning nursing interventions to improve the mental health of university students. Methods : Data were collected from September 1 to September 30, 2015 by giving a questionnaire to 272 university students. The instruments for this study were life stress, self-efficacy, and depression. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and multiple linear regression with the SPSS/WIN 18.0 program. Results : There were significant correlations among life stress, self-efficacy, and depression. Additionally, self-efficacy had a mediating effect on the relationship between life stress and depression. Conclusions : Based on the findings of this study, health management programs focusing on stress management and self-efficacy improvement are highly recommended to promote good mental health in university students.

본 연구의 목적은 영재학생과 일반학생의 시간관리 행동과 생활만족도를 조사하고 시간관리 행동과 생활만족도의 관계를 조사하는 것이다. 이를 위하여 경기도 소재 영재학급 중학생 104명과 중학교 일반학생 203명을 대상으로 설문조사를 실시하고 자료를 분석하였다. 본 연구에서 얻어진 결과는 다음과 같다. 첫째, 영재학생과 일반학생의 시간관리 행동은 유의미한 차이를 나타내었다. 영재학생의 시간관리 행동이 일반학생보다 유의미하게 높았다(p<.05). 영재학생은 성별에 따른 시간관리 행동에 유의미한 차이가 나타나지 않았다. 그러나 일반학생은 성별에 따라 유의미한 차이를 보였으며 여학생이 남학생보다 시간관리를 잘하는 것으로 나타났다. 이원변량분석 결과 집단과 성별 간에 유의미한 상호작용효과는 나타나지 않았다(p>.05). 둘째, 영재학생과 일반학생의 생활만족도에는 유의미한 차이가 나타났고, 영재학생이 일반학생보다 생활만족도가 유의미하게 높았다(p<.05). 영재학생과 일반학생 모두 성별에 따라 생활만족도에 유의미한 차이가 나타나지 않았으며 집단과 성별 간 상호작용 효과가 유의미하지 않았다(p>.05). 셋째, 일반학생과 영재학생의 시간관리 행동과 생활만족도 간의 상관관계를 조사한 결과 두 집단 모두에서 시간관리 행동과 생활만족도 간에 유의미한 정적 상관관계가 있음을 밝혔다. 시간관리 행동이 생활만족도에 미치는 영향을 알아보기 위하여 회귀분석을 실시한 결과 시간관리 행동이 생활만족도에 유의미하게 영향을 미친다는 결과를 얻었다.

Purpose: The purpose of this study was to estimate life time of halogen lamps and acceleration factors using accelerated life test. Methods: Voltage was selected as an accelerating variable through the technical review about failure mechanism. The test was performed at 14.5V, 15.5V and 16.5 for 4,471 hours. It was assumed that the lifetime of Halogen lamps follow Weibull distribution and the inverse power life-stress relationship models. Results: Mean lifetimes of pin and screw types were 19,477 hours and 6,056 hours, respectively. In addition, acceleration factor of two items are calculated as 4.8 and 2.2 based on 15.5V, respectively. Conclusion: The life-stress relationship, acceleration factor, and MTTF at design condition are estimated by analyzing the accelerated life test data. These results suggest that voltage was very important factor to accelerate life time in the case of halogen lamps and the life time of pin type is three times longer than screw type lamps.

The purpose of this study is to verify the soundness of homelife and the stress of home management perceived by housewives living in Seoul as well as to investigate how the soundness of home life affects the stress of home management. In total, 914 housewives were studied to serve as a data sources. The major result are as follows : 1. Communication variables huts the strongest effect on the soundness of home life. 2. Wife's self-actualization influences the soundness of home life and home management stress. 3. Wife's internal-external control has an positive effect on the soundness of home life and home management stress. 4. The soundness of home management variables-family unification, time, psychological health, human ability, physical health should be developed as human capital.

Life Cycle Assessment (LCA) aims to analyze possible impact upon manufacturing process and availability of products, and also study the environmental considerations and potential influence during entire life cycle ranging from procurement, production and utilization to treatment (namely, from cradle to tomb). Based on high-density polyethylene (HDPE) pipe manufacturing of company A, this case study would involve evaluation of environmental influence during the production process. When the manufacturing process has been improved during "production process" and "forming cooling" stage, it is found that capital input on "electric power" and "water supply" could be reduced, thus helping to sharpen the competitive power of company A, and also ensure sustainable economic and industrial development in accordance with national policies on environmental protection.

A web-based program life-cycle management(PLM) system is introduced to implement the system engineering processes and to provide the development traceability online. This information system aims for the realization of essential system engineering management techniques currently applied to the space launch system development program including management of configuration and data based on the work breakdown structure(WBS), WBS, bill of materials and mass properties. The system enhances communication and gives access to the development data with relevant information such as data-to-data relation and approval status/history through the web, and preserve all of the development data throughout the program life-cycle. Further improvement of the system is planned to implement the program management processes and co provide integrated information useful for the programmatic decision making.

One major development in bridge life cycle cost analysis (LCCA) in recent years is to develop deterioration model for bridge components so that the times of repair/replacement throughout a component's life span can be properly determined. Taiwan also developed her own bridge LCCA model in 2003, integrating with the bridge inspection database in the local bridge management system (T-BMS). Under the framework of the local LCCA model, this study employs the reliability method in developing a deterioration model of bridge components. A component deteriorates through time in its reliability, which represents the probability of a component's condition index exceeds a user specified threshold. Model assumptions and rationale are described in the paper. The steps for applying the developed model are explained in detail. Results and findings are reported.

Background: The purpose of this study was to investigate the effects of dental hygiene students' communication ability and conflict management types on adaptation to college life improve adaptation to college life and to suggest strategies to play a role as a professional dental hygienist in clinical practice. Methods: The subjects of this study were selected by random sample extraction of dental hygiene students from two colleges in Gyeonggi and one Chungcheong area. The survey was conducted online for dental hygiene students from July 20 to October 31, 2020. In order to comply with research ethics, this study was investigated with the consent of the subjects. The sample was analyzed for the final 351. Results: Dental hygiene students' communication ability was 3.74 points, conflict management types was 3.01 points, and adaptation to college life was 3.30 points. In the type of conflict management according to the general characteristics, the problem-solving method, the avoidance method, the compromise method, and the concession method showed statistically significant differences in major satisfaction. Among the types of conflict management, the highest positive correlation (r=0.613) was shown in the relationship between the problem-solving method and the compromise method. Factors influencing the adaptation to college life were concentration, forced method, self-disclosure, conversational coherence, and social relaxation. Conclusion: This study is significant in that it derives sub-areas of communication ability and conflict management types that influence adaptation to college life. In the future, there is a need to improve the quality of dental hygienists by continuously conducting research on the types of conflict management targeting dental hygienists, and responding more proactively and actively to conflict situations in the clinical field.
