The purpose of this study was to develop the group counseling program for elderly decreasing the level of depression and preventing suicidal ideation and to evaluate the effectiveness of this program. The subjects of this study were 18 elderly people who are older than 65 years old, they were divided into 2 groups: the experimental group(n = 9) and control group(n = 9). The experimental group participated in the group counseling program. The programs of these experimental groups were implemented twice a week for 90-120 minutes per session over 6-week period. But there were no treatments for the control group. The pre-test, the post-test and the follow-up test were implemented in order to evaluate the effectiveness of the program. The instruments used in the study were the Korean Dementia Rating Scale, the Geriatric Depression Scale Short Form-Korean Version and the Scale for Suicidal Ideation. The data were analyzed by Mann-Whitney U Test and Wilcoxon Matched-Pairs Signed Ranks Test. The findings of the study were as follows: The experimental group had significant effects on decreasing the level of depression and the suicidal ideation. Meanwhile the control group were increasing the depression and did not show any significant change in the suicidal ideation. Based on these findings, the limitation of the study was discussed, and further research was suggested.

This study estimates the cost function through offshore fishery cost data and analyzed the economies of scale of Korea's offshore fishery. For the estimation of the cost function, translog cost function was used, and the analysis implemented the panel analysis of the panel data. Also, annual economies of scale of the offshore fishery and economies of scale of 14 offshore fisheries in 2015 were analyzed using translog cost function coefficient estimation. The analysis result of economies of scale of Korea's offshore fishery showed that with the exception of 2003, economies of scale exist in all periods of time. However, as it almost reaches the minimum efficient scale, it was revealed that further scale expansion will bring inefficiency. Thus, according to the analysis result, Korea's offshore fishery requires a scale reduction policy rather than scale expansion policy, and this seems to coincide with the current government's fishery reconstruction policy and its practice such as the fishing vessel buyback program. The analysis result of economies of scale of each offshore fishery in 2015 showed that economies of scale of each offshore fishery exists with the exception of five trawl fisheries such as large pair-trawl and large otter trawl and large purse seines. This strongly suggests that the five fisheries and Large Purse Seines with non performing economies of scale need urgent scale reduction and should be the first target for the government's fishery reconstruction policy.

The production of Korean offshore fisheries has been gradually decreasing due to the severe depletion of offshore fisheries resources caused by excessive fishing efforts. The production of the offshore fisheries in 2016 was the lowest since 1975. So the federal and local governments in Korea adopted and implemented various fisheries management plans and policies in order to restore fisheries resources. However, these plans and polices have not been successful in re-establishing fisheries resources. Thus, in order to accurately diagnose the situation with regard to offshore fisheries, this study sought to estimate not only the return to scale by fishing gear of offshore fisheries, but marginal productivity of individual fishing gear based on production factors derived from offshore fisheries production functions. The study was organized in the following manner. First of all, this study estimates production functions of offshore fisheries. The Cobb-Douglas and the translog production functions are adopted as offshore fisheries production functions. Specifically, the functions are estimated by crew, vessels, and offshore resource as production factors. The offshore resource is estimated by the Clarke Yoshimoto Pooley model based on the surplus production model. Secondly, the fisheries production functions are extended to the fixed-effect model and the random-effect model with panel data. Thirdly, this study analyzes the return to scale of offshore fisheries and the marginal productivity of the production factors from the estimated offshore fisheries production function. In conclusion, this study suggests plans and countermeasures for productivity improvement by group (labor intensive or technology intensive) based on the characteristics of individual offshore fishing gear.

This article estimates the economic values of changes in water quality of the Paldang Watershed by using the Choice Experiment (CE). The conditional logit model estimation results show that a small improvement in water quality from the 'status quo' level to the level of 'very good' increases average household's monthly utility by 3,157 Won, whereas a water quality degradation down to the 'normal' level gives rise to an increase in the monthly average utility by 9,649 Won. The corresponding social gain and loss of water quality changes to the Metropolitan Area were thus estimated about 285 billion Won and 872 billion Won, respectively. This article seems meaningful in that it resorts to the new water ecosystem classification criteria and indices that are respondent-friendly. They help a CE study like this to overcome one of its critical weakness that the number and contents of attributes of a CE study can quickly add to the information overload problem, especially where the environmental good under investigation is hard for ordinary respondents to understand.

PPPs(Public Private Partnerships) in Korea was introduced in 1990s, which mainly used for providing transportation facilities such as railroad and high-way. Since 2005, a service delivery type PPPs, in other words BTL(Build Transfer Lease) has been implemented, which focused on social infra-structure including school, military housing, and sewage facilities. According to previous literature, efficient risk evaluation and management is the key factor for successful PPPs in the UK and Australia. However, Korea doesn't have proper risk evaluation system for PPP type project. In this paper, we explore and analyze risk evaluation system of PPPs in Korea and other countries. Also, we apply empirical methodology used in the UK to a BTL project and set up a new PSC(Public Sector Comparator) with risk evaluation.

This study aims to analyze causality among Wando abalone producer prices by size using a vector autoregressive model to expiscate the leading-price of Wando abalone in various price classes by size per kg. This study, using an analytical approach, applies a unit-root test for stability of data, a Granger causality test to learn about interaction among price classes by size for Wando abalone, and a vector autoregressive model to estimate the statistical impact among t-1 variables used in the model. As a result of our leading-price analysis of Wando abalone producer prices by shell size using a VAR model, first, DF, PP, and KPSS tests showed that the Wando abalone monthly price change rate by size differentiated by logarithm were stable. Second, the Granger causality relationship analysis showed that the price change rate for big size abalone weakly led the price change rate for the small and medium sizes of abalone. Third, the vector autoregressive model showed that three price change rates of t-1 period variables statistically, significantly impacted price change rates of own size and other sizes in t period. Fourth, the impulse response analysis indicated that the impulse responses of structural shocks for price change rate for big size abalone was relatively more powerful in its own size and in other sizes than shocks emanating from other sizes. Fifth, the variance decomposition analysis indicated that the price change rate for big size abalone was relatively more influential than the price change rates for medium and small size abalone.

This study aimed to clarify the effect of information technology (IT) education on the efficiency and effectiveness of working processes among agriculture corporations. Survey data on information levels from 222 agriculture corporations were collected from the Korean Agency of Education, Promotion, and Information Service in Food, Agriculture, Forestry, and Fisheries (EPIS) for a governmental white paper. Structural equation modeling was used for analysis. This study found that IT education increases the ratio of the use of information systems in working processes, especially given the use of data accumulated through information and communications technologies (ICT). The findings of this study suggest that the use of ICT data as an aspect of IT education is beneficial for the agricultural sector.

1. Partly because of Freud's greatemphaiss on the important of the child's successful weathering of the oedipal crisis and on the need to home both parents present if that period is to be successfully resolved, there has been a good deal of research on the effects of the absent father on the child's development. 2. Compared with boys whose fathers remained at home, boys were more immature and less secure in identification with their fathers. Some evidence suggests that father-absent children, particullarly boys suffer unusual difficulties in social relations wit their peers. 3. Emphasis on family quality , harmony, or climate as more important than father's absence, person is another recurrent finding among studies that attempt to analzed family factors in relation to juvenile deliquency. 4. The fatherless boys were more often judged to be anxious about sex and to be more effminated. 5. The sex-role problems of the boy without a father probably refect a number of factors, obviously they relate in part to the simple fact that he has not had a man around to provide a model of maliness. 6. Father is important to a girl's sex-role development not only because he is particularly interested in sex typing but also because he provides her with an opportunity to relate intimately to a man and to learn what it is like to invest emotionally in a male. 7. It is conceivable that children of broken marriages are more sensitive to martial problems and more ready than others to end an unhealthy relationship ; it is also conceivable that they are less likely to enter into a healthy one. 8. In some cultures it simply reflects the extreme amount of intimacy mother has with her son as compared with the amount of time compared with the amount of time father has available to spend with him.

The purpose of this study was (1) to investigate changes in house and kitchen forms and behaviors in the kitchen area of Korean family houses from the Yi-dynasty to the present, and (2) to develop a housing conceptual framework on the basis of the ecosystem approach through analysis of changes in Korean family houses. The documentary research method wad used fro this study. The major findings were that the traditional Korean houses were composed of separate buildings and had various floor levels with the maru(a wooden floor) as the center of the open plan. The introduction of foreign style house forms from the era of enlightenment, in the year 1876 to the Korean war in 1950 changed traditional Korean houses into Korean-western style houses. More recent increased population and urbanization accelerated to change from the traditional Korean house form to an apartment style. At the present time, however, many kinds of house forms, from a highly modernized style with convenient facilities to a primitive style, which cannot even meet the basis needs of daily life, coexist together. The Kitchens in traditional Korean houses had no plumbing, drainage, or work centers. They had simple adobe furnaces which were used for cooking and for heating the ondol, a kind of panel heated floor by which the heat and smoke run under the floor to the chimney. This made the kitchen floor level lower than the floors of other spaces. The residents entered the kitchen through the madang(atrium). The influence of the western style kitchen, the development of technology, and improvements of nation-wide economic status have made today's kitchen space covenient and hygienic. The floor level of the kitchen was raised to the same level of other spaces. Formerly the major function of the kitchen was raised to the same level of other spaces. Formerly the major function of the kitchen space was cooking and heating floors. This had changed, and the kitchen is now, the place for family and social interaction. A housing conceptual framework was developed on the basis of these findings.

The main problem of consumer behavior is choice since the outcome of me of a choice can only be known in the future, consumers are forced to deal with the risks of und\certainty. So, perception of risk is pivotal aspect of consumer behavior. This study was designed to investigate the relationships between purchasing behavior of textile and perceived risk. Data were obtained from 276 housewives. ANOVA, x2-test were employed to analyse the data. The result were : 1. general features of textile purchase behavior are as follows. Blend wools and pure wool products are prefered. Fall is the major season in purchasing textile. Wholesalers, department stores and agent stores are prefered. Purchasing decision making process independent upon not only textile itself but the practice value of the textile. Purchasing textile, married young women depend on outward shape of the textile, middle and old aged groups depend on the economic value of the textile and the credibility of the stores. 2. Perception of risk is relatively high in the preference of store, color/design, and psycological uncertainty. But the perceived risks is relatively low in brand, price and social credibility. 3. There is significant relationship between the recognition rate of risk and the sensitiveness of the consumer. In addition, there are strong relationship between the risk rate and the preference of shop, brand, and price. On the other hand, there are no significant relationship between the color, design, and sociopsyco-logical risk and demographic variables. 4. The perceived risk of consumer would be a key stone to grasp the consumer behavior. The product company needs to provide full information which could reduce the perceived risk of consumer. there attitude would help for the mutual interests. In the future research, we need to develop the precise methods for finding variables on the perceived risk during the process of making purchase intention.
