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.

본 연구에서는 ALBC3 합금에 Ni기 자용성 합금으로 내마모성 및 내캐비테이션 특성을 향상시키기 위하여 용사코팅 후 열처리를 실시하여 캐비테이션 특성을 평가하였다. 본 연구 결과, 자용성 합금 코팅층이 높은 경도를 나타내어 내마모성이 우수할 것으로 판단되나, 다공질의 조직으로 인해 열악한 내캐비테이션 특성을 나타냈다. 따라서 열처리 조건의 최적화가 중요하며, 본 조건에서는 열처리 온도를 높여 자용성 합금 내 B와 Si의 유동성을 증가시킴으로써 기공이나 결함을 제거하여 특성개선 효과를 기대할 수 있을 것으로 판단된다.

미세전자-기계계 (MEMS)의 윤활 막으로 적용되는 자체조립 단일막 (SAMs) 형성을 위하여 실란 변성 퍼플루오로폴리에테르 (SPFPE)를 합성하고 이를 실리콘 표면에 코팅하여, 형성된 SAMs에 의한 표면 특성 변화를 기존의 퍼플루오로폴리에테르 (PFPE), 옥타데실트리클로로실란 (OTS), 그리고 퍼플루오로옥틸트리클로로실란 (FOTS) SAMs와 비교 검토하였다. SPFPE에 의해 형성된 SAMs는 실리콘 표면과의 느린 반응성에 의하여 OTS와 FOTS와 비교하여 상대적으로 낮은 소수성을 가지나 열처리에 의하여 이들과 비슷한 소수성을 보였다. SPFPE에 의하여 형성된 SAMs 표면은 OTS와 FOTS와 유사한 0.3 nm의 표면 거칠기를 가지나 상대적으로 유연한 PFPE 주사슬의 움직임으로 인하여 OTS에 비하여 50% 정도 마찰력이 줄어드는 우수한 마찰 특성을 보였다.

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.
