Purpose: This study was designed to construct and test structural equation modeling on healthy menopausal transition in middle-aged women in order to identify variables affecting healthy menopausal transition. Methods: Participants, 276 women, 45 to 60 years of age, with menopausal symptom score higher than 5 on the Korean version of Menopause Rating Scale, were recruited in three cities and one county of Gyeongnam Province. Research data were collected via questionnaires and analysed using SPSS version 18.0 and AMOS version 20.0. Results: After confirmatory factor analysis, one of the observed variables was excluded due to relatively low factor loading. The model fit indices for the hypothetical model were suitable for the recommended level: GFI=.93, CFI=.92, RMSEA=.05. Self-efficacy, self-differentiation, and menopausal symptoms explained 67.7% of variance in menopausal transition, and self-differentiation was the most influential factor for menopausal transition. Self efficacy and menopausal symptoms explained 9.6% of variance in menopausal management, although "menopausal symptoms" was not significant. Conclusion: These results suggest that nursing interventions to improve self-differentiation, self efficacy, menopausal management and decrease menopausal symptoms are critical for healthy menopausal transition in middle-aged women. Continued development of a variety of community-based nursing interventions to facilitate healthy menopausal transition is suggested.

Physically-based WEPP watershed version was applied to a watershed, located at Jawoon-ri, Gangwon with very detailed rainfall data, rather than daily rainfall data. Then it was validated with measured sediment data collected at the sediment settling ponds and through overland flow. The $R^2$ and the EI for runoff comparisons were 0.88 and 0.91, respectively. For sediment comparisons, the $R^2$ and the EI values were 0.95 and 0.91. Since the WEPP provides higher accuracies in predicting runoff and sediment yield from the study watershed, various slope scenarios (2%, 3%, 5.5%, 8%, 10%, 13%, 15%, 18%, 20%, 23%, 25%, 28%, 30%) were made and simulated sediment yield values were analyzed to develop appropriate soil erosion management practices. It was found that soil erosion increase linearly with increase in slope of the field in the watershed. However, the soil erosion increases dramatically with the slope of 20% or higher. Therefore special care should be taken for the agricultural field with higher slope of 20% or higher. As shown in this study, the WEPP watershed version is suitable model to predict soil erosion where torrential rainfall events are causing significant amount of soil loss from the field and it can also be used to develop site-specific best management practices.

The purpose of this paper is to investigate the piecewise wise polynomial approximation for the curved boundary. We analyze the error of an approximated solution due to this approximation and then compare the approximation errors for the cases of polygonal and piecewise polynomial approximations for the curved boundary. Based on the results of analysis, p-version numerical methods for solving Dirichlet's problems are applied to any smooth curved domain.

This study examined the effect of home informatization on housewives' home management ability. The questionnaires of 338 housewives who have at least one child were analyzed. LISREL 8.5 version program was used to examine the obtained data. As a result, degree of practical usage of information had positive effect on the home management ability directly. Internet use and information communicative machine usage also had affected the home management ability indirectly.

In this thesis, we suggest questionnaire which is designed to understand of what employees include executive think about 6 sigma management movement and to find important factor for strategic of success 6 sigma management movement of K. Corporation. This thesis is composed of 2 parts, one is questionnaire design and the other is questionnaire analysis. We find important factor for strategic of success 6 sigma management movement of K. Corporation by using correlation and regression analysis, which results very useful and great help for K's Co. In questionnaire analysis, we use by minitab package version 13.2.

최근 근거리 무선통신(NFC, Near Field communication)에 대한 관심이 급증하고 있다. 이 논문에서는 출결체크시간을 최소화하기 위해서 NFC 기술을 활용한 출결관리 시스템을 제안한다. 각 강의실에는 책상마다 NFC 태그를 부착하고, 학생들은 스마트 폰에 내장되어 있는 NFC 인식기능을 이용하여 출석을 확인한다. 출결관리 시스템은 교수용 PC 웹 프로그램, 학생용 안드로이드 프로그램으로 구성되며, 학생들의 출결정보를 효율적으로 확인함으로서 교수에게 더 많은 강의시간을 제공할 수 있는 장점을 갖는다. 이 논문은 NFC를 이용한 출결관리 시스템의 프로토타입을 제안하고 구현함으로써 다양한 교육기관에서 본 시스템의 활용 가능성을 검증하는데 기여하였다.

정확한 홍수빈도와 강도의 추정은 홍수위험관리 및 피해감소에 중요한 역할을 담당하고 있다. 미국에서는 설계수문량 산정을 위한 Log Pearson Type-III (LP-III)와 매개변수 추정을 위한 모멘트법을 일괄적으로 적용해오고 있다. 1965년 홍수빈도해석 가이드라인인 Bulletin 15가 처음으로 만들어진 이후 이를 개량해 나아가 현재에는 Bulletin 17B가 가이드라인으로 사용되고 있다. 최근에 Bulletin 17C가 기존 가이드라인의 부족한 부분을 보완하고 새로운 방법들을 흡수하여 거의 완료상태에 있고 곧 출시될 예정이다. 본 연구에서는 새로이 보완된 Bulletin 17C에 대한 중요사항들을 분석하고 이를 적용하여 보았다. 분석결과들로부터 우리나라 설계홍수량 산정방법 및 절차의 개선방안에 대하여 고찰하였다.

Purpose: The aim of this study was to examine the validity and reliability of the Korean version of the self-efficacy for managing chronic disease 6-item scale (SECD-6-K). Methods: The English version of the Self-Efficacy for Managing Chronic Disease 6-item Scale first underwent forward and backward translation procedures. The SECD-6-K was then used to collect data from 350 adults diagnosed with chronic diseases. Content, construct, convergent, discriminant, and criterion validity were all evaluated. Reliability was assessed using Cronbach's α. SPSS 25.0 and the data were analyzed using AMOS 26.0 software. Results: The SECD-6-K consists of six items in two domains: disease management and health behavior. The results for construct, convergent, and discriminant validity were good. Exploratory factor analysis produced eigen values between 2.27 and 3.28, with factors total explained cumulative variance of 91.1%. Confirmatory factor analysis supported goodness of fit and reliability for the modified SECD-6-K model. The criterion validity also showed significant correlation with both the Patient Health Questionnaire and 12-item Short-Form Health Survey version 2. Finally, reliability was found to be excellent. Conclusion: This study identified the high reliability and validity of SECD-6-K. The SECD-6-K is an appropriate tool for determining Korean patients' self-efficacy in managing their chronic conditions. Therefore, this scale may be used in clinical settings as well as in educational and research settings.

When small organizations construct and operate Knowledge Management System(KMS), there exists inefficiency in employee participation and system usage. In recent years, web itself is evolving into web 2.0. And It is crucial to utilize web 2.0 characteristics into KMS. The problems in the original version of KMS(KMS 1.0) is as follows. KMS is separated from Offline and electronic work processing systems. Even information in the electronic work processing system cannot be accessed by employees of other divisions in the same organization. Now web 2.0 environment provides more enhanced user participation and information sharing. It also reinforces KMS 1.0 into KMS 2.0. Small organizations should take advantage of web 2.0 environment and construct the better version KMS of its own with low-cost and high-efficiency.
