Recently many administrative institutes try to improve the viability of rural villages. For increasing the viability, not only infrastructures but internal vitality is necessary in rural villages. Nonetheless, most of governmental projects have been focused on infrastructures. For this reason, RDA(Rural Development Administration) designed and performed the RHL(Rural Healthy and Longevity village) project. This RHL project is not easy to evaluate the outcome because it consists of very intangible project items. In this paper, we developed a scoring model to evaluate the result of the RHL project. The scoring model based on DEA(Data Envelopment Analysis) was suggested to evaluate the quantity of personal activities in each village. Personal activities are classified into five categories: regional life, social life, productive life, outdoor life and indoor life. Evaluating indices of each category are developed and weighting values are evaluated by AHP(Analytic Hierarchy Process). The developed model was applied to Kumsan village and examined its applicability.

The IRR(internal rate of return) is often used by investors for the evaluation of engineering projects. Unfortunately, it has serial flaws: (1) multiple real-valued IRRs may arise; (2) complex-valued IRRs may arise; (3) the IRR is, in special cases, incompatible with the net present value (NPV) in accept/reject decisions. The efforts of management scientists and economists in providing a reliable project rate of return have generated over the decades an immense amount of contributions aiming to solve these shortcomings. Especially, multiple internal rate of returns (IRRs) have a fatal flaw when we decide to accep it or not. To solve it, some researchers came up with external rate of returns (ERRs) such as ARR (Average Rate of Return) or MIRR (MIRR, Modified Internal Rate of Return). ARR or MIRR. will also always yield the same decision for a engineering project consistent with the NPV criterion. The ERRs are to modify the procedure for computing the rate of return by making explicit and consistent assumptions about the interest rate at which intermediate receipts from projects may be invested. This reinvestment could be either in other projects or in the outside market. However, when we use traditional ERRs, a volume of capital investment is still unclear. Alternatively, the productive rate of return (PRR) can settle these problems. Generally, a rate of return is a profit on an investment over a period of time, expressed as a proportion of the original investment. The time period is typically the life of a project. The PRR is based on the full life of the engineering project. but has been annualised to project one year. And the PRR uses the effective investment instead of the original investment. This method requires that the cash flow of an engineering project must be separated into 'investment' and 'loss' to calculate the PRR value. In this paper, we proposed a tabulated form for easy calculation of the PRR by modifing the profit and loss statement, and the cash flow statement.

At present, the manufacturing industry is in a process of a great change. There is a demand for a variety of types and shorter product life. The change increases the number of different tools and frequencies of tool changes. For the most part, the tools are presetted and offset values are entered manually or via punched tapes to NC machines. Thus a large amount of capital is tied up in the tool area and considerable productive time is lost. Consequently, there is a need for improvement in tool management. This paper describes a computer controlled tool data management system which include: 1) tool identification with bar code. 2) computer aided management and updating of tool data. 3) tool data communication with tool presetter, CNC, etc.

최근 들어 인간의 수명 연장과 출산율 저하로 노인인구가 기하급수적으로 증가하여 고령사회로의 진입에 대비하여 여러 가지 정책적 대안 등을 제시하고 있는 현실이다. 이러한 해결방안의 하나로 노인들의 적극적인 사회참여와 생산 활동을 유도하고 풍요로운 삶을 영유하도록 할 수 있는 것이 유비쿼터스 환경을 구축하는 것이라 할 수 있다. 최근 IT기술의 발달에 따라 인간의 모든 생활에 지능형 컴퓨터를 접목하여 생활을 더욱더 편리하고 생산적인 환경을 구축하려 노력하고 있다. 이제는 단순하게 노인이 컴퓨터에 접속하게 하는 것이 아니라 노인 사용자들이 효율적이며 생산적으로 사용하도록 개선하는 노력이 따라야 한다. 대안으로 떠오르는 유비쿼터스 컴퓨팅의 효율적 인터페이스를 위한 유저인터페이스 디자인 기준을 제안하여 노인의 불편을 조금이나마 개선하고 삶의 질을 향상시키는데 일조하고자한다. 유비쿼터스 환경이 노인의 생활환경을 개선함은 물론 객체적 생활인으로서 삶을 영위해 나갈 수 있다는 점을 전제로 본 연구를 진행하였다. 따라서 노인의 특성을 분석하여 노인을 위한 효율적 인터페이스 디자인방법을 제안함으로서 새로운 유비쿼터스 시대에 노인의 경계를 허물고 사회적 활력을 이루는 계기가 되었으면 한다.

Glyceollins, one of the inducible phytoalexins produced by plants, were induced in a number of varieties of Korean soybean through fungal infection. Of the tested soybean varieties, Tae-Kwang, though not the most productive, was found to be currently the most suitable for the induction of glyceollins. Amongst the fungal species, Rhizopus microsporus var. oligosporus was seen to be the most effective elicitor. Halved soybean seeds produced glyceollins upon fungal infection; however, chopped soybeans and homogenized soybeans did not produce significant quantities of glyceollins.

This study aims to understand the meaning that learning of the old age has, through old age learners who augustly live after retirement-life so called successful silver years. Qualitative research methods is used for analyzing the contents of articles about 15 old age learners and the results are follows below. First, the retirement has dual meaning for the old learners. One is they experienced psychological and emotional insecurity after retirement and the other is it is a turning point for them to realize their longtime dream. Second, the old age learners showed enthusiasm about learning and they voluntarily found the way of success in their silver years. Finally, the old age learners working in new career with provocative and enthusiastic attitude work as a role model of successful old age life and show how they progress. This study argued that we need to consider the old as active agents and the old age as the time when productive and continuous learning can be done. In addition, this study strongly insisted that we need to realize the importance of 'education by the elderly' and social and other relevant conditions are needed to be established immediately.

This ethnographic case-study explores the interpretation and behavior in job considering among full-time housewives. The participants of this study are eleven middle class full-time housewives in their thirties and forties. In-depth interviews based on an unstructured Questionnaire were conducted for this study. Findings are as follows: Six full-time housewives tend to think their full-time housewife-lives more convenient, something unable to substitute and more profitable compared to the counter partner's lives. But they are classified into two groups according to the satisfaction for full-time housewife life. One group has found out more positive meaning in their life but the other group has not yet and they are doubtful about real life and other opportunity. In Contrast, other five full-time housewives tend to interpret employment as a more productive source to secure family resource for their children's education and repay the loan used to buy larger apartment. And the job is considered to confirm her own individuality and the feeling for the social entity as a competent social entity. But two of them who have never been employed do not try to get a job as a new identity alternative. And the various elements like household income, job experience, health, children's age and husband's attitude to his wife's employment etc. are defined to influence the interpretation and the job considering behavior among full-time housewives.

The present study examined the effect of parent-adolescent communication style and school life satisfaction on the relationship between depression and suicidal ideation among adolescents. The participants were 1,099 middle school and high school students in Chungnam province. The instruments used were the 'Parent-Adolescent Communication Inventory', 'The Center for Epidemiological Studies Depression Scale', 'Suicidal Ideation Questionnaire', and 'School Life Satisfaction Scale'. The collected data were analyzed by t test, F test, the Scheff$\'{e}$ test for a post hoc test, Pearson's productive correlation, hierachical multiple regression, and Cronbach's ${\alpha}$ for reliability by SPSS program(18.0 version). The results were as follows: First, there were significant differences in parent-adolescent open communication style, school life satisfaction, and suicidal ideation by school level, and in the relationship with the teacher in school life satisfaction by gender. Second, the more depressed they were, the more they had suicidal ideation by school level and gender. Also, the more they communicated openly with their parents and the more satisfied they were with their school life, the less depressed they were and the lower degree of suicidal ideation they had. Finally, there were significant effects of both parent-adolescent communication style and school life satisfaction on the relationship between depression and suicidal ideation among adolescents.
