This paper presents energy self-sufficiency simulated in municipal wastewater treatment plants (WWTPs) by adopting solar energy production systems that vary with installation conditions. Relative to the national average energy consumption in WWTPs, the employment of 100 kW photovoltaics (PVs) was simulated to achieve 2.75% of energy self-sufficiency. The simulated results suggested that the installation of PVs toward South or South west would produce the highest energy self-sufficiency in WWTPs. When super-hydrophilic coating was employed in the conventional PVs, 5% of additional solar energy production was achievable as compared to uncoated conventional PVs. When 100 kW of PVs were installed in a future test-bed site, Kihyeung Respida located in Yougin, Sourth Korea, the energy self-sufficiency by solar energy was simulated to be 1.77% (2010). The simulated energy self-sufficiency by azimuth(direction) will be useful reference for practitioners in designing the solar PV systems in the WWTPs.

This study was motivated from the proposition that readiness for self-sufficiency is important for future independent life of poor adolescents. This study focused on analyzing the effect of empowerment as a mediator as well as analyzing the effects of predictive factors of readiness for their self-sufficiency. For conducting this study, a survey method was used on 240 poor adolescents residing in Seoul. This study used path analysis method for analyzing mediator effect of empowerment. In the results, Statistically significant variables that had effect on readiness for self sufficiency through empowerment(intrapersonal, interpersonal, sociopolitical) were family relations and peer relations. Participation in social organization variable had a positive influence on readiness for self-sufficiency through interpersonal empowerment and sociopolitacal empowerment. Problematic variable had a negative influence on readiness for self-sufficiency through interpersonal empowerment. Such results provided knowledge foundations for diverse social work approaches related to promoting empowerment. Specifically, this study shows that diverse social services are necessary for promoting poor adolescents readiness and social work interventions are necessary for strengthening adolescents empowerment.

This study aims to identify effects of welfare-to-work programs that helped welfare recipients promote emotional and social self-sufficiency, focused on social adaptation program for the hardest-to-employ poor with psychological and social work barriers. This study relied on data from mandatory social adaptation program participants among community self-sufficiency organizations in nationwide from December 2010 to January 2011 in South Korea. Hierarchical regression was used to analyze for this study. As a result, among participants, there were slightly than moderate level on emotional and social self-Sufficiency effects. The satisfaction of education program had positive effect both emotional and social self-sufficiency whereas that of health service only had positive effect on social self-sufficiency. Also, these emotional and social self-sufficiency effects differed between the number of needy family in household, type of organization and degree of satisfaction of life. This study suggests that discussion of implications for the development of welfare-to-work program and intervention that target psychological, emotional and social needs for recipients with work barriers.

This qualitative study is designed for the reconstruction of the experience of single mothers in poverty based on the bottom-up approach. Welfare dependency is identified as vital help to protect their own and children's lives, through their stories telling that welfare services provided by government and community take care of them "in place of their husbands", and "raise them up by hand." What is self-sufficiency to them is more of a process-orientation through welfare dependency than a state out of it, and a way to look through building their self-esteem and working to discover their self-worth except their economic power. Restoring their potential to self-sufficiency through dealing with their psycho-social stresses and expanding services for them related to child-care(education) and occupation ability development for long-term self-sufficiency, rather than hasty focusing on welfare exit, should be built on the foundation of helping them self-sufficient. In order for the self-sufficiency program to overcome the participant's images of "subordination and stigma" and to convey the original meaning of "welfare to work", the performance and evaluation system of self-sufficiency programs that reflects the insider's perspectives on their participation motive and process, and the self-sufficiency program customized for their needs and interests should be encouraged to develop.

This research attempts to consider the influence of the green-contacts on the consciousness of the dwellers in the residential area of Nara. The consciousness of the dwellers is investigated by questionaire which deals with verdure, green-sufficiency and the green-contacts of dwellers. Five districts of the old residential area in Nara were selected and surveyed. The results of analysizing the investigated data summarized as follows. 1. The dwellers have a tendency to satisfy the greenery although the size of open space is small. Accordingly, the green-sufficiency is the available scale to investigate the greenery on the consciousnss of the dwellers. 2. Dwellers contact with the green space of housing as well as the surrounding failiarized-green. It was understood that the green-contacts of dwellers characterized by the kind of greenery, means and their frequency. 3. The familiarized-green contacts with the dwellers is related to the private and public uses. 4. In order to satisfy the feeling of green-sufficiency, the greenery space should be increased; it was found that green-sufficiency is satisfied by increasing the greenery space. 5. In the case of small open space, it is also possible to satisfy and attitude of green-sufficiency by introducing the familiarized-green, even if the rate of greenery space is low.

This paper aims to analyze inequality of maize self-sufficiency rate among countries in 1970-2011. Utilizing sub-group consistency of Generalized Entropy and Atkinson inequality index, the estimated maize self-sufficiency rate inequality is further decomposed into two steps' separate country groups. First, lower and upper income groups and then lower, lower middle, upper middle and high income groups are used based on the national classification of the world bank. It is inferred that 1980s' policy intervention and 1990s' Uruguay Round negotiations have different effect on the inequality among four different country groups.

The main purpose of this study is to investigate whether the gap of fiscal self-sufficiency rates of 16 provincial governments in Korea has been narrowed and to suggest some remedies based on the empirical results. The panel data set from 1998 to 2013 is used and pooled OLS and system GMM regression techniques are employed. The fiscal self-sufficiency rates show downward trend and ${\beta}-convergence$ exists in absolute and conditional convergence analysis. The speed of conditional convergence anlysis is proved to be faster than that of absolute analysis. Both metropolitan cities and prefectures show convergence of fiscal self-sufficiency rates. We have found out that in the case of metropolitan cities, the proportion of workers in the tertiary industry has positive effect on fiscal self-sufficiency rates and in the case of prefectures number of cars per capita has positive effect. And in both cases increase in old population has negative effect.

Under the goal of investigating the difference of staff perceptions in performance evaluations at local self-sufficiency centers, this study set out to examine whether differences would be found between team leaders or those in higher positions and the common staff in criteria, procedures, implementation, rewards, and feedback of performance evaluations. For that purpose, the investigator conducted a survey by mail with staff working for local self-sufficiency centers in 15 cities and provinces across the nation from September 6 to 30, 2010. Of 672 questionnaires that were distributed, 439 were returned. Of these, a total of 432 were used in latent mean analysis. The major findings are as follows: first, the staff at local self-sufficiency centers had a relatively negative perception of performance evaluation in terms of rewards for evaluation results. Secondly, the team leaders or those in higher positions had a more negative perception of performance evaluation in terms of evaluation criteria and rewards for evaluation results than common staff. Based on those findings, the study offered some implications with regard to performance evaluation systems at local self-sufficiency centers.

This study compared the individual, family, environmental factors, and subjective sleep sufficiency according to gender among Korean adolescents and to examine relevance among the individual, family, environmental factors, and subjective sleep sufficiency. The subjects were 65,528 Korean adolescents(male: 33,803, female: 31,725), who were derived from the 12th Korea Youth Risk Behavior Web-based Survey 2016 in South Korea. As a result, the prevalence of the subjective sleep sufficiency in this study was 33.4% male and 19.5% female. The subjective sleep sufficiency was affected by the depression experience, suicidal ideation, school achievement, feeling of stress, feeling of happiness, subjective health status, alcohol experience, smoking experience, substance experience, allergic rhinitis, and atopic dermatitis in individual factors; economic status, educational level of parents and living arrangement in family factors; school grade, school type and emotional support in environmental factors in both males and females. In individual factors, breakfast eating and asthma affected the male's subjective sleep sufficiency and physical activity affected the female's. The mental health of the individual factors was the most influential factor in adolescent's subjective sleep sufficiency. Therefore, nursing intervention to improve Korean adolescent's subjective sleep sufficiency should be applied considering gender differences.

This study was conducted to comprehend the current status of regional self-sufficiency of Hospital injury inpatients and, based on this, to prepare some measures for improving the self-sufficiency. For this purpose, 2005 & 2008 Patient Survey data, regional medical utilization data of National Health Insurance Corporation, yearbook of Central Emergency Medical Center and evaluation results of emergency medical institutions were obtained. Frequency analysis, cross-tabulation, decision tree and logistic regression techniques were used in the analysis of data. Self-sufficiency in 'metropolitan city/Do' area was lowest for Chungcheongnam-do for the year 2005 and 2008, followed by Gyeongsangbuk-do, Gyeonggi-do and Jeollanam-do. As for the self-sufficiency in 'Si/Gun/Gu' area with regard to local medical supply, for both 2005 and 2008, It was higher when general hospital, district emergency medical center, regional emergency medical center and regional emergency medical institution existed in the residential area. It was also found that, the higher the quality level of local emergency medical institution, the higher the self-sufficiency. It was confirmed that, when promoting the national policy for injury patients, priority should be placed on 'Do' area where the level of emergency medical supply was low, and that enhancing the quality level of emergency medical institutions was helpful for the improvement of self-sufficiency.
