사회경제적 지위(혹은 위상) 개념이 심리학에서도 많이 사용되어 왔지만 많은 문제점들이 노정되어 본 연구에서는 이를 특정하고 이를 해결하는 방안을 모색하였다. 연구 결과, 이 지표로 사용되는 것으로는, 직업, 교육수준, 수입, 빈곤 수준, 부의 수준, 가족구조(가족 수), 사회적 통합 수준, 주택 소유 여부, 물질적 생활 조건, 가계소비단위당 수입, 경제적 어려움, 경제적 만족, 밀집도, 공적 지원수준 등이 있다. 이들 지표들 중 몇 개를 선택하여 측정한 후 지표들을 따로 따로 하나씩만 사용하는 경우도 있고, 이들 지표들을 통합적으로 사용하는 경우도 있다. 따라서 본 연구는 이들 문제를 해결하기 위해 첫째, 이 개념을 적용하지 않고 단순히 이 지표 한 두 개를 사용하려면 SES라는 개념을 사용하지 말아야 한다. 둘째, 이 개념을 적용하려면 이들 개별 지표들을 사용하는 것은 부적절하고, 통합된 지수 형태로 사용해야 할 것, 마지막으로, 우리 문화에서 이들 지표들 중 중요한 것을 선정하여 통합적 지표로 사용해야 할 것을 제안하였다.

The purpose of this study is to understand and analyze the satisfaction level of users regarding the search and search results of D College Library system implemented by Open API. For the study, 90 students of D College searched the library system with 4 subjects regarding on current affairs and assignments, and then evaluated the satisfaction on search functionality and contents usability. In results, they satisfied search expansion in general. Especially, the satisfaction levels for the convenience of search method and preview was the highest, but that of level for the arrangement and browsing of search results and the searching speed was the lowest. In terms of currentness, relevance, usefulness and utilizability aspects, Naver was the most highly evaluated, followed by library’s database, dissertation/academic journals, Youtube and Flikr. The cause of the unsatisfactory could be reduced when the library system implements the useful and attractive search interface.

In this study, a research model was designed and verified in order to determine whether the communication styles of public library managers affect employees' empowerment, job satisfaction, and life satisfaction. A survey was conducted among employees of four public libraries in the Gyeonggi region and 24 libraries in Seoul, and 229 valid responses were analyzed. The analysis revealed that authoritative communication style influenced employees' job satisfaction, while social communication style influenced their empowerment. Additionally, employees' empowerment impacted their job satisfaction, which in turn affected their life satisfaction. This implies that job satisfaction and life satisfaction of the employees can be achieved after communication and empowerment were well established within the organization. This study is meaningful in suggesting an effective management direction for strengthening the essence and foundation of public libraries by examining the theoretical significance and implications of the research result. This study also suggested that in the future, another research should be conducted based on a variety of characteristics by integrating the different communication styles of researchers.

OPAC is a very important interface for user to use and search library collection and electronic resources. The purpose of this study is to analyze empirically the impact of OPAC usability on user satisfaction and loyalty in an university library setting. The OPAC functions investigated are keyword searching, integrated searching, faceted navigation, relevance ranking, spelling check, recommendations, user participation, and Really Simple Syndication(RSS), etc. This study investigated what usability effects on user satisfaction and loyalty and suggested the way to improve user satisfaction and loyalty.

The purpose of this study was to investigate the current status and problems of the social service delivery system for women in Korea, and to suggest ways to improve its function. The current social service delivery system in the public sector contains a network of services connected with the Division of Women's Welfare in the Ministry of Health and Social Welfare. This study focused on evaluating the function of the public service delivery system from the perspective of the service providers. A survey of 167 civil officers in charge of women's welfare services in the city.county.district administrations, and 202 women's welfare counselors around the country was conducted in order to evaluate their current duties, effectiveness of services, and problems of the current system Six criteria including integration, continuity, accessibility, adequacy, efforts and professionalism were used for evaluating the effectiveness of the social service delivery system for women. According to the survey, the civil officers and women's counselors gave relatively favorable ratings for their job effectiveness and job satisfaction. However, their duties involving guidance and counseling of prostitute women and operation of women's welfare councils received least favorable evaluation. Moreover, in terms for job satisfaction, these service providers were less satisfied with their working conditions than their relationships with clients or colleagues. In addition, budget and personnel shortages were the most serious problems facing the delivery system Further analysis showed that professionalism and accessibility of the service delivery system had positive impact on job effectiveness while efforts, integration, accessibility and adequacy had positive impact on job satisfaction of the service providers. These findings have potential implications for designing more effective social service delivery system for women.

This paper presents a systematic approach for estimating material performance and designing mix proportion of concrete based on an application of Bayesian method in the form of satisfaction curves. The one-parameter satisfaction curve represents a satisfaction probability of a concrete performance criterion as a function of concrete material parameter. An analysis method to combine multiple satisfaction curves to form one unique satisfaction curve that can relate the performance of concrete to a single evaluating value called Goodness value is proposed. A proposed PBMD procedure and examples of application of the PBMD method for concrete mix proportion design are carried out to verify the validity of the proposed method. Finally, the comparison between the expected performance results of a concrete mix proportion designed using PBMD to the ACI estimation equation calculated results are performed to check the applicability of the method to actual construction.

The purpose of this study is to examine the mediating effect of depression and social relationships on the effects of physical satisfaction on life satisfaction of multicultural adolescents. For this purpose, data from the 7th year of the 2017 Multicultural Panel (MPAPS) surveyed among young people were used. The sample was subjected to frequency analysis, descriptive statistics, and correlation analysis to identify the characteristics of 1,146 students in the first year of high school at the time of the survey. In addition, the mediating effect of depression and friendship was analyzed, and as a result, it was found that depression and friendship were partially mediated in the effect of physical satisfaction on life satisfaction of multicultural adolescents. Based on the research results, it is significant in that it provides basic data on programs and practical implications that can be used in the social welfare field to reduce depression and promote amicable friendships for multicultural adolescents to improve life satisfaction.

The purpose of this study is to identify the direct effects of PSM on job satisfaction (JS) and perceived job performance (PJP) in public institutions and to identify indirect effects of the mediator. In particular, we define the person-organization fit (POF) used as the mediator as the fitness of the personnel system and identify the influence of POF in the relationship between PSM, JS, and PJP. The questionnaires used in this study were conducted for the members of Changwon Public Health Center and empirical analysis using structural equation modeling was conducted and the following results were obtained. First, PSM in the integrated public service organization has a positive effect on JS and PJP. Second, PSM shows that JS and PJP of organization members are improved through mediating effect of POF. It can be concluded that PSM can improve JS and PJP through institutional fit between members and organizations.
