The purpose of this study is to provide convenience to the senior center staff and policy makers through a research of "Life satisfaction" in the senior centers with a systematic review and meta-analysis of the considerations of the elderly, published in foreign journals for the past 10 years. We searched published studies in the Medline Complete, Pub-med central and Scopus databases from January 2007 to November 2017. The main key words used "Elderly AND(And OR aged) AND Personal Satisfaction/ or life satisfaction" and out of 595 searched articles a total of 6 studies were selected. After qualitative analysis of the contents of the study, meta - analyzes were conducted for factors with more than three quantitative values. The factors affecting life satisfaction of the elderly were physical health (pooled effect size 0.582, p = .000), mental health (pooled effect size 0.423, p = .000), economic problems (r = .51, p =. 001), social activities, and daily living. It is expected that this study which provides an understanding of life satisfaction of the elderly would contribute to provide general information for developing social consensus on the employment in the super aging society should help improve the quality of welfare facilities for senior citizens in the future.

This study examined the changes of depression and life satisfaction among the elderly living together in group-home and congregate housing. And in this course, it was to verify the practical effects of the recent government and local authority community life of elderly people by comparing them with the groups of elders living alone. The study was divided into Time 1 and Time 2, and 205 person's data were used for the final analysis. PASW Statistics 18.0 was utilized to analysis the data of this study, because it is difficult to explain the results of this analysis, secondary qualitative research has been used to identify additional contextual information. The major results of this study are as follows. First, the depression of the subjects was significantly improved in the case of living in group-home and congregate housing, and it was significantly worse in the group of elders living alone. Second, the life satisfaction of survey subjects was significantly improved when living in congregate housing, group-home was significantly worse, and the group of elders living alone were not statistically significant but slightly worse. Third, mixed research methods were applied to make accurate interpretation of changes of life satisfaction of the elderly living in group-home. Based on the results of this study, it is possible to establish appropriate measures for the elderly to improve early adjustment and quality of life in community life. And the community life of the elderly can contribute to a real social safety net by solving the blind spot of welfare. At the national level, it can be utilized as a standard reference to improve and strengthen existing policies by providing data that can simultaneously examine the performances and problems of various policies related to housing or the welfare of the elderly.

The purpose of this study is to analyse the mediating effects of spirituality on the relationship between functional capacity and depression among the elderly. The conceptual framework was based on the integrated theory by Brief et al.(1993) to life satisfaction. The sample was collected through convenience sampling of 413 elderly persons who were 65 years of age or older drawn from senior welfare centers, community senior centers, and religious institutions in Seoul, Incheon, and Gyeonggi Province. Data analysis was performed using Structural Equation Modeling(SEM). The main findings of the present study are as following: First, spirituality had the mediated effects on which depression and IADL influenced life satisfaction. Particularly, existential spirituality on life satisfaction had larger effect size than religious spirituality. Second, the results showed that religious spirituality had positive effects on existential spirituality. These findings demonstrate that the development and implementation of programs geared for fostering religious spirituality and existential spirituality of senior citizens are needed to improve life satisfaction in the field of social welfare. To this end, the foundation of spiritual practice in the field of social work with older people should be constructed through a spirituality-related system and professional training.

The purpose of this study is to identify the characteristics and factors of each area by considering the gender health of the elderly as the integration of mental, physical, emotional, and social gender health based on the WHO gender health. The sexual health of the elderly is significantly different by gender, academic background, and region, and there is a clear difference in mental, physical, emotional sexual health and social sexual health. The mental, physical and emotional sexual health of the elderly in urban areas, those with high education and male is high, but the elderly in the rural areas, those with low education, and female are high in social sexual health. The factors affecting sexual health are as follows. Mental sexual health was positively influenced by satisfaction of sexual life and sexual knowledge. Physical sexual health was positively influenced by life and spouse satisfaction, and emotional sexual health was positively influenced by sexual relationship, spouse satisfaction, sexual life satisfaction and sexual knowledge. Social sexual health has a negative (-) effect on spouse satisfaction and sexual relationships. Integrated sexual health in old age can affect subjective health and quality of life, leading to successful aging. Sexual health education is needed to form a safe and healthy sexual life and interpersonal relationship. The 'sex' that appears as a cumulative trajectory of life should be accompanied by the accurate sexual health awareness and sex education that encompasses all generations. Therefore, in the composition of sex health education program, it is necessary to reflect the components that can enhance the sensitivity of adulthood to strengthen understanding and communication of spouse.

In general, a product consists of one or more parts. Different parts of a product can perform the same function. According to "the design hypothesis of an integrated part", parts having the same function may be integrated into one part. A part can also perform more than one function. The form or material characteristic of a part may perform its function. In this study, we develop a method for defining the functions of components and for integrating parts having the same functions. We have successfully integrated some parts of a three-hole punch using the proposed method. The results satisfy axiomatic design.

Constraint Programming and Optimization have developed in different fields to solve common problems in real world. In particular, constraint propagation and linear Programming are their own fundamental and complementary techniques with the potential for integration to benefit each other. This intersection has evoked the efforts to combine both for a solution method to combinatorial optimization problems. Attempts to combine them have mainly focused on incorporating either technique into the framework of the other with traditional models left intact. This paper argues that integrating both techniques into an old modeling fame loses advantages from another and the integration should be molded in a new framework to be able to exploit advantages from both. The paper propose a declarative modeling framework in which the structure of the constraints indicates how constraint programming and optimization solvers can interact to solve problems.

The study designs and implements a KORMARC/EAD integrated system for the Myongji Digital Library Collections. The purpose of this paper is to design the metadata to Myongji Korean History Collections to provide digital information of high quality to clients, and to develop and implement a model for managing digital library collections. In order to test the model and the quality of the derived metadata, we built a metadata management system, which is connected to the existing KORMARC system. The system consists of two modules- a retrieval and an input module. While in the retrieve mode, one can retrieve KORMARC records of books and archival items, with links to modified EAD files for archival items or to image files for books, in the input mode, one can type two types of data such as a catalog data and an inventory data. Finally, we evaluated the proposed system via mail questionnaires, and propose three suggestions to make this system a much more comprehensive and effective system.

하천과 저수지의 수질을 예측하고 관리하는데 수리 수질예측모형이 널리 활용되고 있다. 수질예측모형은 유역이나 수체 내의 오염물질 이동경로나 농도를 수치해석 방법으로 계산하여 사용자가 필요로 하는 지점과 시점에서의 수질자료 생산하는데 활용되고 있다. 수질예측모형은 검 보정을 통해 정확도를 확보하며, 정확도의 확보를 위해서는 높은 수준의 전문성을 필요로 한다. 특히 시행착오법으로 모형을 보정하는 경우 많은 시간과 노력을 필요로 하게 되며, 보정계수를 과대 혹은 과소로 모형에 적용하는 오류를 범하기 쉽고 모델러의 주관이 관여되기 쉽다. 그래서 본 연구에서는 CE-QUAL-W2모형의 조류항목에 대한 모형 보정을 위하여 Chl-a와 남조류세포수에서 주로 활용되고 있는 보정계수에 대한 민감도 분석 결과를 토대로 매개변수별 모의결과 변화율을 산정하였으며, 시기적 경향성을 재현하기 위해 Ensemble-Bagging 기법과 머신 러닝 기법을 적용하여 모형 구동횟수를 최소화 할 수 있는 방법으로 구성하였다. Chl-a를 보정하기 위한 매개변수는 9개를 선정하였으며, 규조류, 남조류, 녹조류에 총 27개 매개 변수를 민감도 분석으로 도출 한 후 예상 변화율 대비 이벤트별 모의치와 실측치 간 %difference가 유사하도록 매개변수를 조정하였다. 또한 각 이벤트 조합의 매개변수 빈도수와 매개변수별 예상변화율, 시기적 조류특성을 고려하여 가중치를 도출하였으며, 1회 보정에 맞춰 Chl-a 모델 실행결과를 %difference로 평가한 후 "good"등급을 만족할 때까지 반복 적용하였다. 남조류세포수의 경우 Chl-a에 맞춰 매개변수 최적화 이후 남조류세포수 농도를 세포수로 환산하기 위한 CACEL에 대해 머신러닝 기법을 적용하였으며, CACEL 추정변화율 회귀식에 따라 평가 한 후 %difference "good"등급 이상을 만족할 때까지 반복 수행하는 방법을 적용하였다. 본 연구에서는 수질예측모형의 정확도를 확보하기 위하여 최적화 기법을 적용하였으며, 이를 통해 모형을 보정하는 과정에서 요구되는 시간과 노력을 줄일 수 있도록 하였으며, Ensemble기법과 머신러닝 기법을 적용하여 모형보정계수 적용에 객관성을 확보할 수 있도록 하였다.

This research developed integrated service assessment index on satisfaction with road use in consideration of not only quantitative parts, such as the existing traffic speed and delay but also qualitative parts, such as traffic information and traffic safety, etc. The newly devised assessment index developed assessment items and weight using ANP analysis method through the existing research results and questionnaire survey on traffic experts and road users. To verify the developed assessment index, this research measured the feeling degree of road users in time of their driving and analyzed the reasons using the brain waves tester; as an analysis result, the speed shown in the existing assessment index was found to have a 35% effect and further, the factors, such as traffic safety and traffic information were also found to have a lot of effects on the road $users^{\circ}{\emptyset}$ feeling degree. Accordingly, the integrated assessment index suggested by this research has its significance in that it is available to assessment in view of users rather than the existing satisfaction with the service in road use, and this index was developed to reflect the needs of the times, such as a fine view of roads, traffic information, and traffic safety.

The purpose of this study is to identify the differences of student satisfaction depending on tutor's content expertise and experience in PBL of nursing. Nursing department, the subject of this study, is operating Hybrid PBL Curriculum that integrates the courses in nursing for all grades. Tutor's expertise was categorized based on their final dissertations and the clinical fields for which they worked. Tutor's experience in PBL is less than one year for beginners and more than 10 years for experts. After the PBL class for 6 weeks, the 3rd grade students were surveyed. The results showed that there was a statistically significant difference in the student satisfaction according to the content expertise, however, the student satisfaction depending on tutor's experience and the interaction effect between tutor's content expertise and experience were not significant. This study has raised the importance of the role of tutor as content expert in PBL. It is suggested that future studies be repeated for more tutors with diverse subject areas and majors to examine the differences between diverse variables other than student satisfaction.
