본 연구는 민원담당 공무원의 감정노동이 사회적 지지와 지각된 스트레스를 매개로 심리적 소진에 어떠한 영향을 미치는지 구조적 관계를 살펴보고, 매개효과를 검증하는 데 그 목적이 있다. 그 결과, 첫째, 민원담당 공무원의 감정노동은 사회적 지지, 지각된 스트레스, 심리적 소진에 정적(+) 영향을 미치고, 사회적 지지는 심리적 소진에 유의한 부적(-) 영향을 미치고 있었다. 지각된 스트레스는 심리적 소진에 정적(+) 영향이 있는 것으로 나타났다. 둘째, 민원담당 공무원의 감정노동과 심리적 소진과의 관계에서 사회적 지지와 지각된 스트레스의 매개효과를 검증결과 부분매개효과가 확인되었다. 개입전략을 효과적으로 수립하기 위해서는 먼저, 매개변인으로 확인된 사회적 지지 강화와 지각된 스트레스의 감소 촉구에 우선적으로 개입하고 적극적으로 개선할 것을 제언한다.

This study examined the effects of family climate, peer support and self-esteem on children's self-regulation. The participants in this study were 369 children (M=11.78 year) who completed questionnaires regarding family climate, peer support, self-esteem and self-regulation. Data were analyzed means by of a Structural equation model using AMOS 7.0. Our results indicated that (1) family climate, peer support and self-esteem were directly linked with children's self-regulation (2) the associations between family climate or peer support and children's self-regulation were mediated by children's self-esteem. These results imply that family climate and peer support are important antecedent variables in predicting children's self-regulation as well as their relative levels of self-esteem.

The current study examined the effects of early social support of first-time mothers on the home environment for their preschool-aged children via the mediation of mothers' depression. The study sample included 755 first-time mothers participating in the Panel Study on Korean Children(PSKC). Using Structural Equation Modeling(SEM), the longitudinal structure from mothers' social support when the child is one year old to the quality of the home environment when the child is 4 years old was examined. The results revealed that mothers' social support at age 1 predicted social support at age 3, which in turn predicted higher quality of the home environment for their children at age 4. The mediation of depression was also significant. Mothers' social support predicted lower levels of depression at both phases and mothers' depression was significantly associated with the quality of the home environment.

This study examines the relationship of adult attachment, social support, and subjective happiness of university students, and confirm the mediating effect of social support in the relationship between adult attachment and subjective happiness. Participants in this study consist of 284 university students enrolled in G city. Data were analyzed using SPSS and AMOS to conduct descriptive statistics, correlation analysis, and a structural equation model. The main findings are as follows. First, Attachment anxiety and attachment avoidance showed negative correlations with social support and subjective happiness. And social support showed a positive correlation with subjective happiness. Second, social support showed a partial mediating effect on the effect of attachment anxiety and attachment avoidance on the subjective happiness of university students. This study is meaningful in providing basic data for educational and counseling interventions that enhance subjective happiness of university students.

Spatial structures as like dome structure have the different dynamic characteristics from general rahmen structures. Therefore, it is necessary to accurately analyze dynamic characteristics and effectively control of seismic response of spatial structure subjected to multi-supported excitation. In this study, star dome structure that is subjected to multi-supported excitation was used as an example spatial structure. The response of the star dome structure under multiple support excitation are analyzed by means of the pseudo excitation method. Pseudo excitation method shows that the structural response is divided into two parts, ground displacement and structural dynamic response due to ground motion excitation. And the application of passive tuned mass damper(TMD) to seismic response control of star dome structures has been investigated. From this numerical analysis, it is shown that the seismic response of spatial structure under multiple support seismic excitation are different from those of spatial structure under unique excitation. And it is reasonable to install TMD to the dominant points of each mode. And it is found that the passive TMD could effectively reduce the seismic responses of dome structure subjected to multi-supported excitation.

Carbon nanofiber (CNF) grown catalytically was chemically activated with KOH to attain structural change of CNF. The structural changes of CNF through KOH activation were investigated by using BET and SEM. From the results of BET, it was found that KOH activation was effective to develop particular sizes of pores on the CNF surface, increasing the surface area of CNF. Activated CNF was applied as an anode catalyst support of fuel cell. The effects of different activation conditions including the activation temperature and the activation time on the specific surface area of the CNF activated with KOH were investigated to obtain appropriate structure as a catalyst support. The 60 wt% Pt-Ru catalyst prepared was observed by using TEM and XRD.

본 논문에서는 건축 구조물에서 널리 사용되는 보-거더 구조계 슬래브에서 분포하중과 차량하중이 작용하는 경우에 지지부가 되는 가로보와 거더의 처짐이 슬래브 부재력에 미치는 영향을 연구하였다. 전체 패널에 한개의 가로보가 존재하는 단일 가로보(one-beam) 구조계 슬래브와 두 개 존재하는 이중 가로보 (two-beam)구조계 슬래브에서 지지부가 되는 가로보와 거더 및 슬래브의 강성을 변화시키면서 유한요소해석을 수행하였으며, 얻어진 결과를 토대로 회귀분석을 수행하여 설계시 지지부 처짐 영향을 고려할 수 있도록 보정계수를 제시하였다. 또한 제안된 보정계수를 대표적인 구조물의 설계방법에 적용시켜 그타당성을 검증하였다.

Purpose: This study was designed to test structural equation modeling of the quality of life of stroke survivors in order to provide guidelines for development of interventions and strategies to improve their quality of life. Methods: The participants in the study were patients who visited the neurology outpatient department of a tertiary hospital in Seoul between June 25 and October 15, 2009. Data collection was carried out through one-on-one interviews. Demographic factors, functional independence, social support, nutritional status, post-stroke biobehavioral changes and quality of life were investigated. Results: The final analysis included 215 patients. Fitness of the hypothetical model was appropriate (${\chi}^2$=111.5, p=.000, GFI=.926, AGFI=.880, RMSA=.068, NFI=.911, CFI=.953). Functional dependency, social support and post-stroke biobehavioral changes were found to be significant explaining variance in quality of life. Post-stroke biobehavioral changes had the strongest direct influence on quality of life. Nutritional status had an indirect effect on the quality of life. Conclusion: To improve the quality of life of stroke survivors, comprehensive interventions are necessary to manage post-stroke biobehavioral changes, and strengthening social support networks that can contribute to enhancing the quality of life of stroke survivors.

Purpose: The purpose of this study was to contribute to the activation of comprehensive nursing care services by comparing and analyzing the working environment and operational status of comprehensive nursing care wards with general wards. Methods: A questionnaire survey was conducted at hospitals operating comprehensive nursing care services. We collected data on patient characteristics, workforce, working environment, and work support facilities of 40 hospitals voluntarily participating in the survey. The collected data were analyzed by dividing it into an comprehensive nursing care ward and a general ward. Results: Compared with the general ward, the comprehensive nursing care ward had fewer hospitalized patients, but the severity of the patients and the need for nursing were high. The number of nurses, assistant nurses, and ward support workers per patient was higher in the comprehensive nursing care ward than in the general ward, and the implementation rate of night shift fixed system, the fixed shift system, and the preceptor system were higher. In terms of structural environment, comprehensive nursing care wards had more room for interviews. Conclusion: The comprehensive nursing care ward had more nursing staff and provided a better working environment than the general ward, but required additional support for the structural environment.
