Purpose: The purpose of this study was to develop a motivation-enhanced self-management (MESM) intervention for irritable bowel syndrome (IBS) and to evaluate its effects on female college students with IBS. Methods: The program was constructed to reflect the conceptual framework of the self-determination theory including autonomous motivation enhancement strategy through the satisfaction of psychological needs. The experimental group (n= 24) participated in the all eight weekly MESM sessions, and the control group (n= 25) received one hour education of IBS. Primary outcome measures were the IBS symptom severity scale (IBS-SSS) and the IBS specific quality of life (IBS-QOL), and assessed at the baseline and at eight and 16 weeks after the allocation. Others were autonomous motivation, self-determined behavior, and psychological distress assessed at the baseline and at eight weeks. Results: The experimental group showed improvement in the IBS-SSS (p< .001) at 16 weeks compared to the control group. They showed markedly more improvement in the IBS QOL (p= .008), but the magnitude of this difference decreased at 16 weeks. The experimental group showed improvements in autonomous motivation (p= .035), self-determined behavior (p= .023), and psychological distress (p= .044) compared to the control group. Conclusion: Study results suggest that the MESM intervention for female college students may effectively improve the IBS-SSS and the QOL.

This study examines how the president's transformative leadership in community child-care centers influence organizational effectiveness through the mediation of teachers' self-efficacy. Survey has been conducted on teachers who work in community child-care centers in the Kwangju and Jeonnam region. The data is analyzed using Factor Analysis, Structural Equation Modeling and structural equation Modeling in order to test the relationship among the president's transformative leadership, teachers' self-efficacy, and organizational effectiveness. The results indicate that the transformative leadership of the president has a positive and significant effect on both teachers' self-efficacy and organizational effectiveness. Moreover, teachers' self-efficacy mediates the relationship between transformative leadership and organizational effectiveness. The results have implications for the importance of the president's leadership and suggest that governmental support should be directed towards the enhancement of the president's leadership in community child-care centers.

Purpose: The purpose of this research is to enhance organizational competitiveness of health centers as well as private medical institutions serving as public health and medical institutions. It tries to help them to cope with the requirements from health consumers, to enhance public health nurses' job performance, Methods: After verifying the reliability of the tool, confirmatory factor analysis was used to detect a model, in which valid path coefficients exist among variables. The detected model was then selected as the subject and its validity was verified. Finally, a structural equation model was applied to verify whether the estimate was suitable for the purpose of this research. Results: As for the nursing organizational culture, the public health nurses considered relation-oriented culture the most desirable. As for the self-leadership, they considered self-compensation the most desirable. It was found that mediating effects of self-leadership was partially significant. Conclusion: To enhance job performance, it is necessary to make a transition from the organizational culture to the relation-oriented culture and it is also necessary to develop a program capable of reinforcing self-leadership. In addition, it is necessary to conduct a research to verify whether such a developed self-leadership program is influential on job performance enhancement.

In this study, cavitation characteristics of a thermal spray coating were evaluated in order to improve durability and cavitation resistance. For a coating material, a Ni-based self-fluxing alloy was thermal-sprayed over a ALBC3 alloy substrate and subsequently modified by heat treatment.The resulted self-fluxing coating layer had relatively high hardness compared to the base material, and thus would be expected to exhibit good durability. However, the cavitation characteristics were deteriorated due to the intrinsic porous structure of the coating. Therefore, it is essential to optimize heat treatment condition during thermal spraying coating process for self-fluxing alloy, and in this research the increase in heat treatment temperature is thought to increase the fluidity of B and Si in the self-fluxing alloy and to remove pores or defects, leading to the characteristics enhancement.

Silane modified perfluoropolyethers (SPFPE) was synthesized as a self-assembled mono-layers (SAMs) thin film for micro-electro mechanical system (MEMS). SPFPE was compared to the Perfluoropolyethers (PFPE) as well as octadecyltrichlorosilane (OTS) and perfluorooctyltrichlorosilane (FOTS) with respect to the development of hydrophobicity in the SAMs surface. SPFPE shows less hydrophobicity than those of OTS and FOTS. Thermal annealing of SPFPE SAMs resulted in the enhancement of hydrophobicity as much as those of OTS and FOTS. The SAMs formed from SPFPE were found to be similar as OTS and FOTS SAMs with smooth R$\sub$a/ values of 0.3 nm. However, the flexible chain mobility of SPFPE resulted in 50% reduction as much as the fiction force in OTS.

Purpose: This study was designed to construct a structural model for explaining mental health status in middle - aged women. Methods: The data was collected by self - reported questionnaires from 206 middle - aged women in Seoul. Data analysis was done with the SAS pc program for descriptive statistics and a PC - LISREL Program for finding the best fit model which assumes causal relationships among variables. Results: The overall fit of the hypothetical model to the data was good, but paths and variables of the model were modified by considering theoretical implications and statistical significances of parameter estimates. Thus it was modified by excluding 3 paths, The modified model showed was good fit to the data($x^2=177.55$, p=.00), GFI=0.908, AGFI=0.860, RMR=0.013, NFI=0.972, NNFI=0.982). Perceived stress, anger expression method, and self -esteem were found to have direct effects on mental health status in middle - aged women. These predictive variables of mental health status explained $66.6\%$ of the model. Conclusion: Programs to enhance mental health status in middle - aged women should include stress management skill, anger expression skill, and self -esteem enhancement skills to be effective.

Due to the limitation of the bandwidth resource and capture resolution of depth cameras, low resolution depth maps should be up-sampled to high resolution so that they can correspond to their texture images. In this paper, a novel depth map up-sampling algorithm is proposed by exploiting the fractal internal self-referential feature. Fractal parameters which are extracted from a depth map, describe the internal self-referential feature of the depth map, do not introduce inherent scale and just retain the relational information of the depth map, i.e., fractal transforms provide a resolution-independent description for depth maps and could up-sample depth maps to an arbitrary high resolution. Then, an enhancement method is also proposed to further improve the performance of the up-sampled depth map. The experimental results demonstrate that better quality of synthesized views is achieved both on objective and subjective performance. Most important of all, arbitrary resolution depth maps can be obtained with the aid of the proposed scheme.

Management of perimenstrual discomfort could be an effective strategy for women's health promotion. This study was designed to develop and test the nursing intervention program for the reduction of the perimenstrual discomfort. The data were collected from a group of 76 female university students (34 in the intervention group, 42 in the control group) during November 20, 1997 and March 10, 1998. Measurements were taken concerning perimenstrual discomfort, self care behavior, and perimenstrual discomfort from both groups, at pre and post intervention. Intervention program involved education, support, counseling, and relaxation training, via individual and group levels over a twelve-week period. Listed are the summarized results : 1. The intervention group had more knowledge con corning perimenstrual discomfort(t=2.290, p=.025), self care behavior(t=3.198, p=.000), and lower perimenstrual discomfort score (t=-4.446, p=.000) than the control group at post intervention. 2. The intervention group showed an enhancement on the knowledge on perimenstrual discomport (t=2.35, p=.025), and decreased the perimenstrual discomfort score(t=-7.36, p=.000). However change of self care behavior was not significant during the intervention. According to this study a developed nursing intervention program is effective for reduction of the perimenstrual discomfort. For a future research, it is necessary that experiments concerning menstruation, and a correlational study of perimenstrual discomfort and stress ill be performed.

Purpose: The purpose of this study was to understand and describe the leadership experience of clinical nurses. Methods: During 2014, data were collected using focus group interviews. Three focus group interviews were held with a total of 20 clinical nurses participating. All interviews were recorded as they were spoken and transcribed and data were analyzed using qualitative content analysis. Results: Fifteen categories emerged from the five main themes. 1) Thoughts on the leadership category: to lead others, to cope with problem situations adequately and to serve as a shield against difficulties. 2) Situations requiring leadership: situation that requires correct judgement, coping and situations that need coordination and cooperation. 3-1) Leadership behaviors: other-oriented approach and self-oriented approach. 3-2) Leadership behavior consequences: relevant compensation and unfair termination. 4-1) Facilitators of leadership: confidence and passion for nursing and external support and resources. 4-2) Barriers to leadership: non-supportive organization culture and deficiency in own leadership competencies. 5) Strategies of leadership development: strengthen leadership through self-development and organizational leadership development. Conclusion: In conclusion, the results indicate that it is necessary to enhance clinical nurses' leadership role in healthcare. Enhancement can be achieved through leadership programs focused on enlarging leadership experience, constant self-development, leadership training, and development of leadership competencies suited to the nursing environment.

The main goal of this program is to build a healthy adolescent culture tv broadening the understanding of adolescents and recognition of the environment as well through the development of educational programs centering on the domains of peer relationships, intimacy in dating relationships and sex, leisure activities, and consumption life of adolescents. The program was carried out to 10 young boys and girls for two days/one night and the major findings of the effects of the program through a qualitative evaluation were as follows: First, the program provided adolescent with a proper opportunity to promote a sense of self-confidence through the self-reevaluation process. Secondly, the program provided adolescents with a chance to firmly recognize to become good friends with others though the enhancement of self-esteem, which helped them to build a healthy peer relationship. Thirdly, adolescents were able to promote their views on sex and sexual decision-making by acquiring a proper knowledge of intimacy in dating relationships and of sex, and by candidly expressing their own opinions on sex with instructors. Fourthly, the program provided adolescents with an opportunity to look back on their leisure life with family members which had been neglected thus far and to renew their recognition of active leisure activities. Fifthly, the program provided adolescents with a chance to reflect on their unplanned consumption life and to be firmly determined to refrain from impulsive purchasing and extravagance.
