There has neither been enough research on how to approach the concept of active aging through an integrated view nor an examination to verify the relationship between preparation for old age and active aging in later life. Therefore, this research aims to verify that the elderly, who have prepared for their later life, affected their active aged life. In addition, by setting up self-efficacy and social support as mediator in the research model, this paper looks into the psycho-social resource mechanism of the relationship in depth. In order to verify the correlation of two variables, the Seoul welfare panel data, a mediating model structured by psycho-social resources created by Seoul welfare foundation in 2010, was used. The total sample size was a group of 1,492 elders aged over 65. When it came to our research methods, structured equation analysis was applied to verify the mediating effect and theoretical background. The results revealed that physical preparation, financial preparation, social preparation and leisure preparation directly affected their active aging level positively, thus, psycho-social resources showed a partial mediating effect between preparation for old age of the past and active aging level. The research implications are as follows. First, this research makes an effort to approach the concept of preparation for old age with an integrated perspective through making a construct by entire preparation types. Second, it will attempt to verify the relationship between preparation for old age in the past and active aging in terms of multi-dimension is meaningful. Third, this research reveals the function of psycho-social resource, self-efficacy and social support within the relationship. As far as the partial mediating effect is concerned, preparation for old age education for the middle-aged class should be modified as a decent field to enhance of the elderly.

In recent, the concept of management is emphasizing the aspects of social welfare, especially in permanent rental housing that most of the residents are very low income households. Although the quality of service for the residents of permanent rental housing was improved comparatively, it still needs to continually change in response to the needs of residents. To figure out the better way of supporting the service for the residents of permanent rental housing, this study examined the role and function of management office and compared perception on management services between management staffs and residents of permanent rental housing. Based on the in-depth interview with 5 managers of permanent rental housing, two types of survey questionnaire (residents/staffs of management office) were developed for the research purpose. A sample of 89 management office staffs and 111 residents were used for the data analysis. Most of the respondents recognized the need of a cooperation system among management office, social welfare center, and residents for providing better management system and welfare service.

The purpose of this research are as follows. The first is to investigate the mediating effect of interpersonal skill on the relationship between the ability to use Internet and social activity among the 50's and 60's. The second is to compare 60's latent mean of core variables with 50's ones in terms of information gap. The data was Seoul welfare panel data made by Seoul welfare foundation in 2008 and the total subject was 941(50's=644, 60's=297). When it comes to the research methods, structured equation analysis for verifying the mediating effect and latent mean analysis for comparing the two groups were practiced. The results of this research are as follows. First of all, interpersonal skill did function as partial mediator. Second, according to the latent mean analysis, the group of 50's showed a more higher level of the ability to use Internet. On the other hand, the group of 60's revealed a more active social participation. In conclusion, Information educational programs should focus on Internet communication skill for enhancing social activities of the elderly and consider the differentiations among the elder generations.

This paper proposes a system that utilizes USN(Ubiquitous Sensor Network), Bluetooth and smart phone to improve the function of senior houses. In typical approach, a system in a senior house either directly accesses the status of elderly people by its sensor or is alerted by elderly people who trigger an emergency bell, derive a decision and take an appropriate action. In addition, it is possible for a designated social worker to check the status of senior patients through monitoring system connected by UTP(Unshielded Uwisted Pair) cables, but the responsible person has to be present to monitor patients' status. However, the new system, suggested in this paper, embed Bluetooth function in a blood pressure gauge, thus the smart phone receives patients' health information such as blood pressure through Bluebooth, if any abnormal event occurs. Consequently, the smart phone sends SMS(Short Message Service) to a responsible social worker or a designated hospital. When this program in the paper becomes a reality, an unmanned system that is able to determine suitable actions for certain events will be established, even if a social worker were absence.

Little empirical study has been conducted concerning board function effectiveness and organizational performance in nonprofit nongovernmental human service organizations in Korea. Using the evaluations of 107 board members and 17 executive directors in Korean Community Chest and 16 regional community chests, this study attempted to examine the level of board function effectiveness and its relationship with organizational performance in these community chests. This study used board function scale developed by Holland and Jackson (1998) to measure board function effectiveness in the following 6 dimensions: contextual dimension: educational dimension: interpersonal dimension: analytical dimension: political dimension: and strategic dimension. This study showed that using 4 points scale, mean of overall board function effectiveness evaluated by board members is 2.62 and mean of overall board function effectiveness evaluated by executive directors is 2.73. That is, it showed that means of overall board function effectiveness are located in the middle point between negative evaluation and positive evaluation. On the other hand, using parametric correlation analysis method, it was found that in these community chests the association between board function effectiveness and organizational performance measured by fund-raising growth rate in $1999{\sim}2000\;and\;1998{\sim}2000$ is very weak and statistically nonsignificant. This study also revealed that using nonparametric correlation analysis method, the association between consensus level in evaluation by board members and executive directors about board function effectiveness, and organizational performance is still very weak and statistically nonsignificant. Finally, this study discussed the direction of future research in board function effectiveness and its relationship with organizational performance and the areas of board management that requires substantial efforts for promoting effectiveness of nonprofit human service organizations in Korea.

The rural elderly population has social capital based on regionalism and kinship, which acts as a positive function in terms of their self-efficacy. Self-efficacy refers to the belief in one's own abilities. In general, elderly people with high self-efficacy maintain a healthy life and age successfully. This study examines how the rural elderly population perceive their self-efficacy and social capital and analyzes the role of social capital as a mediating variable. Social capital consists of 4 aspects; trust, norms, network and participation. For this study, data were gathered from 344 rural elderly people aged 60 years and over. The results of this study were as follows. According to the analysis of the structure equation modeling effect, the direct effect of subjective health status on self-efficacy, the indirect effect of the parameters of norms and the total effect were all statistically significant. Second, the direct effect of adult children's support on self-efficacy was significant, and the indirect effects of the parameters of trust, norms and total effect were all statistically significant. This study confirmed that social capital has a mediating effect on the relationship among the subjective health status of the rural elderly, adult children's support and self-efficacy. Furthermore, social capital had a positive impact on the self-efficacy of the rural elderly. Based on these results, a policy for making use of the social capital of the rural elderly should be developed.

Job satisfaction is an important part of social workers who strive to improve the quality of life and independence of their clients. The goal of this study was to reveal the correlation between social workers' self-efficacy, job satisfaction, and supervision to determine whether supervision regulated the effect of social worker's self-efficacy on job satisfaction. In addition, the effect of social worker's self-efficacy on job satisfaction was grasped, and the control effect of supervision regarding the process of social worker's self-efficacy on job satisfaction was identified. For the study, 150 social workers at 10 community welfare centers in Gyeonggi-do and North Seoul area were surveyed, and the statistical program PASW (SPSS) 25.0 was used for data analysis. As a result of the study, it was confirmed that the social worker's self-efficacy had a significant effect on job satisfaction, and that the social worker's self-efficacy had a significant static effect on job satisfaction. In addition, in the process of social worker's self-efficacy affecting job satisfaction, the mediating effect of the supervision function (administrative, educational, and supportive) was found to be significant, so it turned out that the supervision function for social workers was crucial to enhance self-efficacy.

This paper aims to investigate epistemic principles and practical virtue items in Confucism about formation of social capital in a community. First, I have reviewed the basic perspective of Confucism utilizing holistic point of view, which is based on the theory of Yum-Yang, and human relationship in terms of role harmony, which is based on the theory of Si-Wi. I have then explored several items, some of which are Jung and Hwa as an internal value criterion, Ui and Ye as an external one. Analyzing other items such as In and Deok as directional items, Chung-Seo and Hyeol-ku-ji-do as epistemic items and Hyo and Ye as practical ones, I have found out that all of them, mentioned above functioned as factors of social capital in a community. Therefore, we emphasize that Confucian epistemic principles and practical virtue items can not only function as components of social capital in modern communities but have useful and practical implications for policy in modern community welfare.

Social welfare maximization in a double-sided auction market is performed by implementing an aggregation-based particle swarm optimization (CAPSO) algorithm for optimal placement and sizing of one Static Synchronous Series Compensator (SSSC) device. Dallied simulation results (without/with line flow constraints and without/with SSSC) are generated to demonstrate the impact of SSSC on the congestion levels of the modified IEEE 14-bus test system. The proposed CAPSO algorithm employs conventional quadratic smooth and augmented quadratic nonsmooth generator cost curves with sine components to improve the accurate of the model by incorporating the valve loading effects. CAPSO also employs quadratic smooth consumer benefit functions. The proposed approach relies on particle swarm optimization to capture the near-optimal GenCos and DisCos, as well as the location and rating of SSSC while the Newton based load flow solution minimizes the mismatch equations. Simulation results of the proposed CAPSO algorithm are compared to solutions obtained by sequential quadratic programming (SQP) and a recently implemented Fuzzy based genetic algorithm (Fuzzy-GA). The main contributions are inclusion of customer benefit in the congestion management objective function, consideration of nonsmooth generator characteristics and the utilization of a coordinated aggregation-based PSO for locating/sizing of SSSC.

The present paper presents a genetic algorithm (GA) to maximize social welfare and perform congestion management by optimally placing and sizing one Thyristor-Controlled Series Capacitor (TCSC) device in a double-sided auction market. Simulation results, with line flow constraints before and after the compensation, are compared through the Sequential Quadratic Programming SQP method, and are used to analyze the effect of TCSC on the congestion levels of modified IEEE 14-bus and 30-bus test systems. Quadratic, smooth and nonsmooth (with sine components due to valve point loading effect) generator cost curves, and quadratic smooth consumer benefit functions are considered. The main aims of the present study are the inclusion of customer benefit in the social welfare maximization and congestion management objective function, the consideration of nonsmooth generator characteristics, and the optimal locating and sizing of the TCSC using real code-based GA to guarantee fast convergence to the best solution.
