Little empirical study has been conducted concerning social worker' empowerment that has very important function on clients' empowerment. Using the sample of 222 social workers selected from 92 community welfare centers, this study attempted to identify social workers' empowerment level and its predictors. This study used the empowerment scale developed by Leslie, Holzhalb, Holland (1998) that focuses on measurement of social workers's empowerment in social work agencies. Using confirmatory factor analysis, it was confirmed that the scale has three factors such as control of work environment, work relationships, and personal work orientation. This study showed that using 5 points scale, mean of social workers' empowerment is 3.67. In identifying predictors of the empowerment, this study used variables from the following aspects: organizational characteristics, job characteristics, and individual characteristics. Using regression analysis, it was found that variables related to job characteristics such as role ambiguities, role conflicts, and skill varieties are statistically very significant predictors of social workers' empowerment. Self-esteem in personal characteristics and participation in decision making and transformational leadership in organizational characteristics are also statistically significant predictors of social workers' empowerment. This study also revealed that self-control and self-esteem variables function as moderator in the relation with variables such as role ambiguities and role conflicts. Finally, this study discussed the direction of future research in social workers' empowerment and the areas that management efforts should be focused on for promoting social workers' empowerment.

The sympathetic nervous system (SNS) or neurotransmitters in the bone marrow microenvironment has been known to regulate hematopoietic stem cell (HSC) functions such as self-renewal, proliferation and differentiation. However, the specific role of neuropeptide Y (NPY) in this process remains relatively unexplored. In this study, we demonstrated that NPY deficient mice have significantly reduced HSC numbers and impaired bone marrow regeneration due to apoptotic destruction of SNS fibers and/or endothelial cells. Moreover, NPY treatment prevented bone marrow impairments in a mouse model of chemotherapy-induced SNS injury, while conditional knockout mice lacking the Y1 receptor in macrophages did not restore bone marrow dysfunction in spite of NPY injection. Transforming growth factor-beta (TGF-β) secreted by NPY-mediated Y1 receptor stimulation in macrophages plays a key role in neuroprotection and HSC survival in the bone marrow. Therefore, this study reveals a new role of NPY in bone marrow HSC microenvironment, and provides an insight into the therapeutic application of this neuropeptide.

Purpose: This study aimed to identify the effect of role conflict, self-efficacy, and resilience on the nursing task performance of emergency department (ED) nurses. Methods: Data were collected from 140 ED nurses working in 6 general hospitals, using self-reporting questionnaires. Data were analyzed using SPSS 23.0, and the analyses included descriptive statistics, a t-test, an ANOVA, the Pearson's correlation coefficient test, and a stepwise multiple regression. Results: Nursing task performance differed significantly in terms of the following general characteristics of the participants: age, marital status, total clinical experience, clinical experience in the ED, and position at the hospital. Nursing task performance was positively correlated with role conflict, self-efficacy, and resilience. Self-efficacy, role conflict, clinical experience in the ED, and resilience were significant predictors of nursing performance, and they accounted for 36.9% of the variance. Conclusion: Self-efficacy was identified as the most significant factor affecting the nursing task performance of ED nurses. Therefore, it is necessary to develop programs to improve the self-efficacy of ED nurses.

The purpose of this study is to classify men in their 20s by their sex role attitudes, and to study their appearance management behavior and inner characteristic variables such as socio-cultural attitudes on appearance and bodily image, which are expected to influence the appearance management behavior of each classified group. For this, a survey of 393 males in the 20s in Seoul and metropolitan areas was conducted. Factor analysis, Cronbach's alpha coefficient, and F-test were conducted on the data. First, as a result of analysis on sex role attitudes, four groups were categorized: Masculinity, Femininity, Androgyny and Undifferentiation. Second, the analysis of individual variables resulted in appearance management behavior being separated into five categories: Interests in fashion, Proper choice of clothing, Importance of bodily attractiveness, Pursuit for personality and Complementation of physical weaknesses. The socio-cultural attitude on 'appearance' was sub-categorized into Internalization, and Awareness, while 'body image' was divided into Cognitive behavioral and Affective aspects. Regarding differences in socio-cultural attitudes for appearance, body image and metro-sexual lifestyle attitudes, the androgyny group produced the highest scores. Based on these results, it can be concluded that people who take care of their physical appearance, cope effectively with social and circumstantial requirements for happiness and success, and respond flexibly and affirmatively.

Thinness has become a symbol for beauty, acceptance and competence for women in our society, and pressure to diet because of this unrealistic standard is one factor reponsible for the increasing incidence of eating disorder. Three hundred fifty college women in the Chonbuk area were surveyed from May to June 1998, to investigate the relationship among body image, eating disorder, dietary intakes, self esteem and sex role identity. This study identified a subgroup of women who were relatively satisfied with their body weight and who did not diet. This group was compared with subgroups of women who were dissatisfied with their bodies and either were or were not restrained eaters. The dissatisfied/dieting women had the highest BMI, binge eating disorder and night eating syndrom, had significantly lower calorie, protein, iron, vitamin B$_1$, and vitamin B$_2$ intake compared with the satisfied/non-dieting women. The dissatisfied /dieting women, who had lower self-esteem compared with the satisfied/non-dieting women, but the frequency of sex role identity was similga among the groups of women. BMI and binge eating disorder were positively correlated(r=0.157, p＜.01), but BMI and self esteem were negatively correlated(r=-0.202, p＜0.01). Especially, binge eating disorder and self esteem were negatively correlated (r=-0.126, p＜0.05).

Recently, the role of information system in a company has been changed a lot because of the rapid change in business environments and the development of information technology. It encompasses not only the supporting role which has aimed at improving business process but also the strategic role of which purpose lies in strategic use of information technology. Achieving this increased role of information system requires more emphasis on development of better and more effective ISP(information system planning). The purpose of this study is to identify organizational factors to affect successful information system planning. For this study, 240 survey questionnaires were mailed and 71 questionnaires were returned. 57 samples were used for the final analysis and 14 samples were excluded from analysis in that they didn't exercise official and systematic ISP. As the result of analysis, the factor which affect effective ISP is internal organization factors(size, ISP time frame, organizational planning resources, management style, organizational culture), not external factors(volatility and competitiveness). Among Internal factors, organizational culture and management style are the most significant factors which affect the effective ISP. The result of this study may have meaning in suggesting the way to develop effective ISP through the formalization of business process, more favorable users attitude toward IS and selection of an appropriate ISP methodology.
