The purpose of this study was to resolve the issues of inferior housing environment and the population decrease in rural community by improving the environment and attracting urban inhabitants. A simulation on the costs and the local programs was operated from a point of view that Pension Insurance House with Long-term Lease and a plan for the program in connection with local resources should be accompanied to attract urban inhabitants. The study was carried out through mainly documents analysis and specialists' opinions. The simulation results are as follows. Firstly, the pre-existing rural housing development projects have only emphasized the hardware, while underestimated the post-management with operating programs. The software should be underlined when Pension Insurance House is developed. Secondly, as a result of the simulation on construction expenditure and the operating and maintenance cost for 30 years, about 82.3 million Wons are necessary residential expenses for 15 years per unit. Thirdly, in case of MUJU County, it has made the most of its pre-existing institutions. It's medical institutions provide medical care system with health education, facilities related leisure and culture offer recreational programs and the local community center and its program of each town helps new habitants adopt to the rural life. Additionally, the employment project of a local welfare center allow people living in a rural community to continue their careers with their talents and interests through local class programs for a life worth living. Lastly, guide for getting information of rural life, local community gathering and preliminary education should be carried out to reduce expectant tenants' incompatibility and assist them settle down early. The community program expansion is also required at the local government level.

In this paper, we configured the panel data of four years using the information of Higher Education In Korea (2010~2013) and studied the influence of tuition and scholarships on the stop-out rate of national university and private university separately through a panel analysis. Three models are implemented considering various variables suck as faculty-student ratios, employment rate, per pupil expenditure, average tuition, and per pupil scholarship. This study showed that the lower net tuition and the higher per pupil off-campus scholarship lowered the stop-out rate at national universities and the lower tuition and the higher per pupil scholarship lowered the stop-out rate at private universities.

Women are unlikely to receive an equal education, compared to men, in rural Korean society despite the equality in labor sharing. To address this issue this research aims to (a) analyze the educational needs for farming skills and daily life management in rural communities, and (b) develop a model for educational programs reflecting regional characteristics for the female farmers in order to make them experts in agriculture. A structured questionnaire was administered, using a group interview method, to 366 female farmers from the Jeonnam, Chungbuk, and Gyeonggi provinces with help of agricultural agents. The major components of the questionnaire dealt with individual peculiarities, educational environment, and curriculum and training subjects wanted by the female farmers. Educational program content was classified as daily life management, scientific farming and agricultural management skills to create systematic and effective programs. It was found that the critical factors for developing educational programs for the female farmers are as follows: a. It is necessary to develop a program combining daily life management skills and farming skills to make the female farmers experts in agriculture. b. Statistically significant differences were found in the female farmers' educational program participation and needs based educational level, age, educational expenditure, farm type, farming experience, and farm scale. Therefore, it is necessary to develop a program considering the fore-mentioned socioeconomic status and farming characteristics. c. It is important to establish an educational system for the female farmer to improve their quality of life as a minority group in Korean society. In addition, it is also necessary to develop public relations program to ensure that female farmers recognize the importance and necessity of the education.

This study examined the factors related to drinking, health, and food habits of college students before and after participating in the activities of temperance club. The survey was conducted on 97 college students who participated in the temperance club. Scores on 'daily amount of alcohol drinking(p<.05)' and 'drinking expenditure(p<.05)' were significantly lower after temperance club participation. Drinking knowledge(p<.05), and health-related factors including 'concerns about health(p<.05)', 'health condition(p<.05)', and 'times of exercise(p<.05)' were significantly higher after temperance club participation. Food habits score was significantly higher after temperance club participation(m=46.0 vs. m=48.8, p<.01). The scores on 'I have three meals a day(p<.01)', 'I don't eat junk foods often(p<.05)', and 'I don't eat out often(p<.05)' were significantly higher after temperance club participation. Particiating in temperance club activities improved the factors related to drinking, health, and food habits. Therefore, we would like to provide the results of this study as basic data for creating a healthy drinking culture.

Using raw data of the 'Family income and expenditure survey,' we find that the earning distribution worsened in Korea after the financial crisis; the gap between ninetieth and tenth percentile grew larger after the crisis more than before. Such a phenomenon is apparent within narrowly defined education and labor market experience variables. We found that the increase in earning inequality came from the rapidly increasing return to the components of skill other than the schooling and experience, which is caused by the increasing demand of skill after the crisis. Therefore, we can interpret the growing demand for skill is an important factor leading the increase in the earning inequality after the Crisis. And then, we think that the reason for the increasing demand for skill after the crisis can be found in the changes of the technology, the organizational and personnel practice, the globalization, and the labor market. We can derive policy implications from this : To narrow the inequality we must invest the industrial demand-oriented education.

The purpose of this study was to investigate the correlation of dietary and serum phospholipid fatty acids composition and serum lipid levels in postmenopausal women. Data about anthropometry, dietary intake, physical activities, serum lipid profile and serum phospholipid fatty acid composition were collected from eighty-five postmenopausal women. The subjects were classified as normocholesterolemia (NC), moderate hypercholesterolemia(MC) and phyperchollesterolemia(HC) according to their serum total cholesterol (TC) levels based on The Guideline for Korean Hyperlipidemia set/published by The Committee for Hyperlipidemia in Korea. The results were as follows. Total energy intake and the ratio of energy intake to energy expenditure were positively related, while dietary fiber intake was negatively related, with serum TC level. Dietary fat intake was positively related with serum LDL-C level. Dietary cholesterol, saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) intake and the ratio of ingested saturated fat and cholesterol to calories (RISCC) were positively related, while the P/S ratio of dietary fat was negatively related, with serum TC and LDL-C levels. Serum phospholipid fatty acids composition was not significantly different among the three groups. SFA of serum phospholipid fatty acids was positively related, while P/S and M/S ratios of serum phospholipid fatiy acids were negatively correlated, with serum TC and LDL-C levels. We recommend that the dietary P/S ratio of postmenopausal women is increased by reducing their dietary SFA intake. With these changes in the diet, serum phospholipid fatty acid composition could be also changed, and serum lipids levels could be improved.

The inbound tourism market is recognized as a vital sector of the tourism industry today, but it is highly volatile due to each country's economic, social, and cultural variables. The causes of volatility vary according to the inbound country, and we intend to revitalize the stabilized tourism industry by minimizing risks. In this study, the portfolio theory was applied to derive the optimal combination for each country to achieve the minimum risk level's maximum growth rate. The number of inbound travelers and the average expenditure per person was simultaneously applied. As a result of the analysis, the best mix by country based on the number of inbound travelers was the UK, the United States, Germany, China, and Japan. Based on average spending, each country's best combinations were Thailand, Middle East, Singapore, Japan, Russia, Hong Kong, and Germany. It is expected to be able to establish a plan to operate the Korean inbound tourism market strategically.

Due to the decrease in the school-age population and government regulations, universities have made great efforts to secure their own competitiveness. In particular, the selection of universities with financial support based on the recent evaluation of the Ministry of Education has become a major concern enough to affect the existence of the university itself. This paper extracts three-year data from 124 major private universities nationwide, and quantitatively analyzes the variables of major universities selected as self-improvement universities, competency reinforcement universities, and universities with limited financial support. As a result of estimating the selection of self-powered universities using the ordered logit model by hierarchically inputting 12 variables, student competitiveness in the metropolitan area (1.318^**), Educational Restitution Rate (4.078^***), University operation expenditure index rate (1.088^***) values were found. Significant positive coefficient values were found in the admission enrollment rate (45.98^***) and the enrollment rate (13.25^***). As a result of analyzing the marginal effects, the increase in the rate of reduction of education costs has always been positive in the selection of self-powered universities, but it was observed that the rate of increase decreases in areas of increase of 150% or more. On the contrary, the probability of becoming a Em-powered university was negative in all sectors, but on the contrary, it was analyzed that marginal effects increased at the same time point. On the other hand, the employment rate of graduates was not able to find direct significance with the result of the selection of Self powered universities. Through this paper, it is expected that each university will analyze the possibility and shortcomings of the selection of Self powered universities in policy making, and in particular, the risk of dropout of selection for the vulnerable field can be predicted using marginal effects. It can be used as major research data for both university evaluators, university officials and students.

PURPOSE. The purpose of this study was to investigate the effects of fasting and high-fat diet feeding on uncoupling protein 3 (UCP3) mRNA levels, uncoupling the respiratory chain and producing heat, of skeletal muscle in rat. METHODS. Fasting experiment: Forty Male Sprague-Dawley rats (5 wk) were divided into non-fasting groups (CON) and fasting groups (FG) for 0 day, 0.5 day (12 hr), 1 day, 2 day and 3 day. The rats of CON were sacrificed at 0 and 3 day. High-fat diet experiment: Forty Male Sprague-Dawley rats (5 wk) were divided into low-fat diet groups (LF) and high-fat diet group feeding for 0 day, 0.5 day (12 hr), 1 day, 2 day and 3 day. The rats of LF were sacrificed at 0 and 3 day. Analysis: Analysis of UCP3 mRNA expression was used by Real-time PCR. RESULTS. UCP3 mRNA levels of FG group were increased according to time course for 2 days- fasting but decreased at 3 day-fasting. UCP3 mRNA of HF were increased during HF diet feeding for 2 day, and peaked at 1 day-HF feeding, but decreased 2 day and 3 day-HF feeding CONCLUSION. Therefore, it may be rational that UCP3 is up-regulation when a large amount of fatty acids influx occurs in skeletal muscles as well as might have a role for fine adjustments of energy expenditure.
