A 10-week feeding trial was conducted to determine the optimum feeding rate of two extruded pellets (EP1 and EP2) and raw fish-based moist pellet (MP) for juvenile flounder. Two replicate groups of the fish (average weight of 27 g) were fed EP and MP three times daily at different feeding rate (satiation and $85\%$ satiation). Weight gain of fish was not affected by diet, but affected by feeding rate. Weight gain with satiation feeding group showed :t tendency to higher compared to that of fish with $85\%$ satiation feeding at the same diet. Feed efficiency of fish was affected by diet, but not feeding rate. Feed efficiency of fish fed the EP1 and EP2 was higher than that of fish fed the MP at the same feeding rate. Daily feed intake was affected by diet and feeding rate. Daily feed intake of fish fed with satiation was higher than that of fish with $85\%$ satiation at same diet, and this variable of fish fed the MP was higher than that of fish fed the EP 1 and EP2. Protein efficiency ratio of fish fed the MP was significantly lower than that of fish fed the EP1 and EP2 regardless of feeding rate. Lipid content of whole body was affected by diet, and that of fish fed the EP2 and MP at satiation feeding was the highest. It can be concluded that satiation feeding will be good and EP is better than MP for growth of juvenile flounder grown from 27 g to 51 g.

In this work, we investigated the images of (unmarried) single women as seen from the viewpoint of married men and women. In-depth interviews were conducted with twenty-seven (married) men and women of ages from twenties to sixties. By carrying out a content-analysis on the interview results, we could extract three different thematic types of images on single women, which are (1) single women seeking some outlet of their passion instead of forming a family, (2) single women who are enjoying a life of unbound liberty, unlike married men and women, and (3) single women who have distinct personalities from married men and women. Each of these three thematic types could be further classified into narrower themes of specific images. From the first theme of single women who are looking for some outlet of their passion instead of forming a family, one could extract two specific image types in which the single women choose their work as the main outlet of their passion, or else they choose self-development. From the second theme of single women who are leading a life of unbound liberty, four different specific types were found, which are single women with sexual freedom, single women enjoying liberty from the bondage of a family, single women who can freely choose men to go out with, single women who have privileges to enjoy consumption and leisure life only for themselves. From the third theme of single women who have distinct personalities from married men and women, four different types of images were found, that are single women who want to avoid the hard reality of marriage life, single women who are selfish and self-assertive and leading a life that is self-centered or one that is centered around communities of only singles, single women who have secret feelings of emptiness and loneliness, and finally single women who can not find satisfaction in their life style. The images of married men and women on (unmarried) single women are based on the perception that 'those single women are different from us because they are not married'. That is, married men and women look upon the life of single women from the perspective of marriage life that they are experiencing.

The purpose of this research is to develop a theme-based integrated teaching/learning plan in clothing, food, and housing in home economics and to apply the developed process in classes for evaluation in order to identify the suitability in schools. The theme-based integrated teaching/learning plan developed on the basis of textbooks consist four sub-themes; choosing($1^{st}$ and $2^{nd)$ lessons), using($3^{rd}$ lesson), processing ($4^{th}$ lesson), and alternatives($5^{th}$ and $6^{th}$ lessons) under the main theme of 'green family life'. The results from 20 individual and group activities showed that the students actively solved the problems when the presented cases were related to their own lives or experiences. The opportunity to implement green life through activities motivated students' willingness to proceed in real life. However, it is vital to assist integrated thinking through various examples before beginning due to students with difficulties connecting the issue from one area to the other during the problem-focused activity. The students' ability to solve the activity workbook had been improved as the lessons continued. From the survey questions on the theme-based integrated lessons, all items associated with integration of clothing, foods, and housing were positively responded. Also, questions regarding general understanding, suitability and satisfaction on the teaching/learning process were marked positive. The conclusion could be that the integrated theme related to clothing, food, and housing in our life would be appropriate for green family life. The theme-based integrated teaching/learning plan is effective in understanding the occurrence of green family life in relation with clothing, food, and housing, identifying the practical ideas implementing green life in those areas, and improving the integrated ability to solve the green life related problems. However, this research has its weakness in generalizing the results due to its limited survey respondents and post-evaluation being the only assessment conducted.

This research is aimed at analyzing and understanding the perception and attitudes of inpatients in a general hospital in Seoul towards the activation of private health insurance. Survey was conducted against 231 inpatients, results of which were analyzed in the methods of frequency analysis, chi square test, and logistic regression. The results are summarized as follows; First, better-educated population who finished college education at least, higher-income population, and people who had more knowledge about private health insurance showed more perception about activation of private health insurance. Second, better-educated population who finished college education at least, higher-income population, those who are insured in existing private insurance, oncological patients, and people who had more knowledge about private health insurance showed more positive attitude towards private health insurance paying for actual damages, long-term care insurance, and income security insurance. Third, age and education were the factors affecting perception about activation of private health insurance. The older the age is, perception was 1.035 times positive towards activation of private health insurance, and those who finished college education or above showed 3.148 times positive perception towards the same. Forth, surgical patients showed 1.087 times more positive attitude towards private health insurance paying for actual damages than internal medicine patients, while oncological patients showed 2.314 times more positive attitude than internal medicine patients. Further, understanding on the activation of private health insurance was 6.014 times higher in the higher understanding group than in the lower understanding group. Intention to use long-term care insurance was 2.692 times stronger in the male group than in the female group, and 3.616 times stronger in the oncological patients group than in internal medicine patients group. Further, understanding on the activation of private health insurance was 3.881 times deeper in the higher understanding group than in the lower understanding group. Intention to use income security insurance was 3.185 times stronger in those who have academic background of under the high school than those over the college, and 4.175 times higher in the group those whose monthly average income is over 4 million won than those under 4 million won. Also, intention to use income security insurance was 4.323 times higher in the group those who are insured by existing private insurances than those who are not insured by those insurances and it was 5.234 times higher in the group of oncological patients than in the group of internal medicine patients. Further, intention to use income security insurance was 3.559 times higher in the group those who thought that out-of-pocket money of the National Health Insurance is too much to bear than those it is quite endurable. Understanding on the activation of private health insurance was 4.875 times deeper in the higher understanding group than in the lower understanding group. There were some suggestions could be made based on the results of this research. First, reinforced publicity and education is needed for the low-educated or low-income group, as there are gaps in the understanding on the activation of private health insurance depending on the degree of education and income. Second, government should prepare administrative complementary measures to solve the problem of adverse selection by the consumer which is foreseen when private health insurances are activated. Third, government should suggest the desirable course of development of private health insurance items to ensure efficient use of enormous fund of private insurance market for health security of the people. Further, institutional complementary measures are needed to convert existing cancer insurances or specific disease insurances to private health insurances paying for actual damages guaranteeing against every kind of disease. Forth, it judged that, not only private health insurances paying for actual damages, but also long-term care insurances and income security insurances are prospective as fields to create fresh demand for insurance industry.

The purpose of this study was to evaluate night time eating habits, dietary habits, and nutrient intake in university students according to residence type. A survey was conducted by administering questionnaires to 664 students. Questionnaire interview and 24-h dietary recall were conducted. Subjects were divided into three groups according to residence type: dormitory boarding (DB group, N=313), self-boarding (SB group, N=246), and living with parents (LWP group, N=105). Average ages in the DB, SB, and LWP groups were 21.3, 22.2, and 22.1 years, respectively. There were no significant differences in body mass index between the three groups. In total, 77.3% of students regularly ate night time snacks. The proportion of students who reported night time eating was 84.0% in the DB group, 73.6% in the SB group, and 65.7% in the LWP group (P<0.001). In terms of food types consumed during night time eating, the DB group showed a significantly higher rate of consumption of fried chicken and flour-based foods than the SB and LWP groups, whereas the SB group showed a significantly higher rate of consumption of alcohol beverages than the DB and LWP groups. Energy, carbohydrates, protein, fat, vitamins, and mineral intakes were significantly higher in the DB group than in the SB and LWP groups. In addition, intake of cholesterol per 1,000 kcal was significantly higher in the DB group than in the SB and LWP groups. Thus, SB and DB students seemed to have more night time eating problems than LWP students. Accordingly, nutritional education is needed to support the development of healthier eating habits, in particular, night time eating habits, among students living in dormitories and in self-boarding situations.

The purpose of this study was to investigate the BMI, dietary behaviors, body satisfaction and factors affecting the weight control interest according to gender of middle school students (195 boys and 251 girls) in Wonju area. The average height and weight of the boys were $164.8{\pm}8.3\;cm$ and $55.5{\pm}12.3\;kg$ respectively. Those of the girls were $158.8{\pm}5.0\;cm$ and $48.7{\pm}7.4\;kg$ respectively. The average body mass index (BMI) of the boys and girls was 20.3 and 19.3 respectively. In both boys and girls, 69.7% of them had regular meals and the main reason for skipping meals was insufficient time to eat due to oversleeping (33.6%). Most of the subjects consumed snacks more than once a day (95.5%). The dietary intake attitude score of the girls ($35.08{\pm}5.91$) was higher than that of the boys ($33.81{\pm}5.45$) (p<0.01). The eating disorders score of the girls ($12.92{\pm}6.22$) was higher than that of the boys ($10.70{\pm}9.82$) (p<0.01). Also, 87.2% of the subjects showed normal behavior and 12.8% of the subjects had eating disorders, but there was no significant difference according to gender. The body satisfaction score of the boys ($30.16{\pm}5.08$) was higher than that of the girls ($28.00{\pm}5.52$) (p<0.001). In general, body satisfaction score correlated positively with dietary intake attitude score, but correlated negatively with eating disorders score (p<0.05). Multiple regression analysis revealed that body satisfaction score was the most significant variable which affected the weight control interest. Therefore, development of the nutrition education program for adolescents will be effective not only for the improvement of dietary behaviors but also for the positive change in the misleading perception about the ideal body shape.

This paper empirically analyzed the relationship between the characteristics of venture business founders and management performance, setting the management strategy as a parameter to provide a suggestion for the survival and development of venture companies that play an important role in the national economy and job creation. Previous studies in Korea have analyzed the relationship between the characteristics of business founders, management strategies and management performance in a single dimension. This paper, however, explained the business performance of a company from a multi-dimensional perspective while setting the characteristics of business founders as independent variables and setting the business strategy of the enterprise as a parameter. The first result of the analysis shows that the characteristics of venture business founders have a positive effect on business performance. In particular, among the characteristics of venture business founders, a progressive spirit has had the greatest impact on business performance. On the other hand, the influence of risk sensitivity was very weak. Second, the characteristics of venture business founders were found to have a positive effect on business strategy. In particular, innovation was an important variable that affected the technological innovation differentiation strategy, and a progressive spirit was the most influential factor in the marketing differentiation strategy. Third, management strategies of venture firms were found to have a positive effect on business performance. In particular, the technology innovation differentiation strategy has a greater impact on business performance than the marketing differentiation strategy. Fourth, it was revealed that management strategy partially has a mediated effect on the relationship between the characteristics of venture business founders and management performance. In other words, it was found that the characteristics of the founders have a direct impact on business performance but if it is linked to management strategy it has an indirect effect on business performance. The results of this study show that business performance improves when venture business founders' personal characteristics and the firms' management strategy are combined.

Most technology-based entrepreneurship(TBE) go through an process of decline or disappear without overcoming the valley of death(VoD). The purpose of this study is to identify the growth dimension of TBE and to test the influence of firms activities on firms growth over time. This study identified the two-dimensional growth dimension divided by size and profit through exploratory factor analysis(EFA) of a number of growth indicators. Then, we defined the discrete state of growth firm in four states, divided by size and profit, and five states, including the closure of business. Multi-nomial logit model is used to predict the effect of TBE activities on a discrete state of growth firm(size×profit, closure of business) based on multiple independent variables. The independent variables are based on five representative firms activities: employment, marketing, R&D, financial activities, and general management activities. The growth stage of TBE over time has been categorized into three stages: early stage, middle stage, and late stage of business, taking into account the main periods during which the survival rate of startups sharply decreases. The analytical data of this study was based on the secondary data of the start-up supporting companies of government and public institutions. The subjects of analysis were TBE within 10 years. As a result of the empirical analysis, the employment and marketing activities of TBE show that early and mid-term activities had an effect on the state of firms growth. However, if there is a difference, employment activities have both positive and negative effects, while marketing activities have only a positive effect on size and profit growth. And besides, R&D activities, financial activities, and general management activities throughout the entire process of firms growth were found to be firms activities that have both positive and negative effects on firms growth. In addition, the age of the founder, the firms' industry, and the geographic location of the firms, which are general characteristics of the company, were found to have a distinctive effect on the growth status of the firms according to the growth stage.

Preliminary feasibility study on Busan metro line #1 in Yangsan line (Nopo-Bukjeong) depending on active volume of mass transportation between Yangsan city and Busan city was conducted. As the study concluded that it's valid, the necessity to establish the metro railroad network connecting to Busan, Ulsan and Gyeongnam Province is demanded to improve the transportation issues in Ungsang area vulnerable to metro service and to drive the balanced development between metropolitan cities. In addition, the volume of transportation depending on methods in target areas and road traffic assignment are surveyed to put a stress on the necessity to establish the metro railroad network. As the demand of transportation for alternative lines is predicted, the budget and benefits for construction for each alternative line set for the rough economic analysis depending on traffic volume for each method and traffic assignment results. The total project budget necessary for construction of proposal line #1 set as effective one among target three lines in this project is calculated in 794.32 billion won. Construction accounts for the most expensive in expenses for project and contingency allowances, purchases for vehicles and collateral expense are followed in orders. However, compensation for lands is not counted. In particular, according to economic analysis in proposal #1, ratio of benefit/cost (B/C) is 0.584, net present value (NPV) is -217.47 billion won, the internal rate of return (IRR) is analyzed in 0.604 %. At the current stage, it is not economically feasible, but the B/C is 0.737 in long-term upon construction of Yangsan line between Wolpheong and Yongdang which is proposal line #3. Therefore, when Busan metro basic plan is reorganized to aim the benefit of residents in Ungsang area vulnerable to the metro service, we think it must be necessary to establish the metro railroad network connecting to Busan-Yangsan-Ulsan which is proposal line #2 by extending the existing Sinjeong line and including this task line in high-ranked plan related to metro railroad.
