Most of countries are trying to increase the supply of renewable energy as the substitute of the fossil energy for reducing greenhouse gas emissions. However, renewable energy sources account for only about 3.86% of the total Korea primary energy supply. To increase the rate of renewable energy in Korea's energy consumption, various policies for expanding the use of renewable energy should be applied. Also these policies should be consider renewable energy resources distribution and regional inequality. In this study, the potentials of photovoltaic, wind power and bioenergy from rice straw, livestock waste and food waste are calculated and the distribution characteristic and regional inequalities are analyzed using Gini's coefficient and Gini decomposition method. As the results, technical potentials of photovoltaic and wind power of city region(Gu) has more potential rate than theoretical potentials. Livestock waste has the most unequal distribution (Gini's coefficient: 0.617) among renewable resources.

The purpose of this study is to develop the life scale of the middle aged homemakers. The life scale are composed of spouse relation 8 items, child education relation 7 items, home economy relation 4 items, homework relation 3 items, selfish health relation 6 items, parent relation 3 items, and interest and social activity relation 4 items.

Purpose: The purpose of this study was to identify predictors of quality of life in burn patients. The predictors of quality of life were the subject's characteristics(marriage, income, burn size, burn site, pain and functional limitation) and personal resources(self esteem and social support). Method: 96 burn subjects who were hospitalized participated in the study. The data analysed was with descriptive analysis, ANOVA, Pearson correlation coefficient and multiple regression. Result: Burn patients who had a spouse and had higher levels of income, with smaller size of burn, no arm burn, with lower levels of pain and functional limitation, plus higher levels of self esteem and social support reported higher levels of quality of life(R2=0.5229). Conclusion: Based on the finding of this study, development of nursing intervention programs including reduction of pain and functional limitation, enhancing self esteem and social support can be suggested.

The purpose of this study is to investigate the family life participation and to analysis its related variables focusing on comparisons of male and female in the secondary students. The questonaire included school environmental variables, family environmental variables, the preference degree of Home Economics, sex role attitudes and the family life participation. The participants were 600 middle and high school students but the final data used on this study were 559. For the statistical analysis of this study, fequency, mean, Cronbach’s ${\alpha}$ coefficient, one way ANOVA, t-test and multiple regression were calculated. The results of this study were summarized as follows；1) The degree of family life participation was a little higher than middle level. While the highest participation degree was family activities participation, the participation degree of household work, communication and decision-making, leisure activities were low. 2) The variables that influence on the family life participation were the level of living and preference degree of Home Economics for both male and female.

Solder joint is the weakest part which connects in mechanically and electronically between package body and PCB(Printed Circuit Board). Recently, the reliability of solder joint become the most critical issue in surface mounted technology. The solder joint interconnection between plastic package and PCB is susceptible to shear stress during thermal storage due to the mismatch in coefficient of thermal expansion between plastic package and PCB. A general computational approach to determine the effect of solder joint shape on the fatigue life presented. The thermal fatigue life was estimated from the engelmaier equation which was obtained from the temperature cycling loading($-65^{\circ}C$ to $150^{\circ}C$). As result of the simulation, TSOP structure has the shortest thermal fatigue life and the same structure Copper lead has 2.5 times as much fatigue life as Alloy 42 lead. In BGA structure, fatigue life time extended 80 times when underfill material exists.

The purpose of this study were 1) to identify the pattern of general life style of the middle classs apartment residents. 2) to examine the types of the home furnishing attitudes of those. 3) to find out the relationships between life style and the home furnishing attitudes. The data were collected using self-administered questionnaire. The respondents were 227 homemakers of the middle class apartment residents, selected through stratified random sampling technique. Data were coded and analyzed using SPSS computer packages. The statistics used were frequency, percentage. Pearson's correlation coefficient, F-test, X2-test, factor and cluster analysis. 6 patterns of life style and 6 types of the home furnishing attitudes were identified.

Purpose: This study aims to investigate the relationships between knowledge on advance directive, attitudes towards the withdrawal of life-sustaining treatment and quality of life among hemodialysis patients. Methods: A descriptive correlational study was conducted with 103 hemodialysis patients. Data were collected using a structured questionnaire from May to September of 2016, and analysed by using descriptive statistics, t-test, ANOVA and Pearson correlation coefficient. Results: The participants' knowledge level on advance directive was $5.47{\pm}2.08$ out of 9, the attitudes towards the withdrawal of life-sustaining treatment was $3.22{\pm}0.49$ out of 5, and the quality of life was $3.35{\pm}0.92$ out of 6. The knowledge on advance directive was positively correlated with attitudes towards the withdrawal of life-sustaining treatment (r=.21, p=.037) and quality of life (r=.21, p=.036). Conclusion: According to the results of this study, the level of knowledge on advance directive is preferred to improve the quality of life of hemodialysis patients. It is needed to support and maintain ongoing education opportunities in order to improve the level of knowledge on advance directive among patients undergoing hemodialysis.

This study examines how economic preparation for later life directly influences life after retirement. As people's life cycle is gradually getting longer, preparation for the later time with less economic activity after retirement is becoming more important. Thus, this study analyzes the factors influencing life after retirement. Data comes from the Korean Retirement and Income Study (KReIS) surveyed carried out by the National Pension Research Institute in 2015. The analysis includes Cronbach's alpha, Pearson Product Moment Correlation Coefficient and Sobel Test. This study confirms that voluntary retirement has a positive influence on life satisfaction. Results are in line with previous research about the relationship between voluntary retirement and retired life. When a person retires voluntarily, financial preparation can be made in advance for retirement. In case of involuntary retirement, people may experience a sense of loss in personal standing and financial difficulties due to the unexpected situation. Especially, early retirement from the main workplace leads to unstable later life. The study's policy recommendation, in particular, calls on government and businesses to agree on social responsibility for helping employees to retire in the predictable retirement time and, thus, enabling the retiree to decide all aspects of the path after retirement.
