A reliability data processing MPRDP (Multi-Purpose Reliability Data Processor) has been developed in FORTRAN language since Jan. 1992 at KAERI (Korean Atomic Energy Research Institute). The purpose of the research is to construct a reliability database(plant-specific as well as generic) by processing various kinds of reliability data in most objective and systematic fashion. To account for generic estimates in various compendia as well as generic plants' operating experience, we developed a 'three-stage' Bayesian procedure[1] by logically combining the 'two-stage' procedure[2] and the idea for processing generic estimates[3]. The first stage manipulates generic plant data to determine a set of estimates for generic parameters,e.g. the mean and the error factor, which accordingly defines a generic failure rate distribution. Then the second stage combines these estimates with the other ones proposed by various generic compendia (we call these generic book type data). This stage adopts another Bayesian procedure to determine the final generic failure rate distribution which is to be used as a priori distribution in the third stage. Then the third stage updates the generic distribution by plant-specific data resulting in a posterior failure rate distribution. Both running failure and demand failure data can be handled in this code. In accordance with the growing needs for a consistent and well-structured reliability database, we constructed a generic reliability database by the MPRDP code[4]. About 30 generic data sources were reviewed and available data were collected and screened from them. We processed reliability data for about 100 safety related components frequently modeled in PSA. The underlying distribution for the failure rate was assumed to be lognormal or gamma, according to the PSA convention. The dependencies among the generic sources were not considered at this time. This problem will be approached in further study.

The purpose of this study was to develop a program for the enhancement of Korean married women's quality of life(LQ) based on the results of the first year study(1996) and the second year research(1998). In order to construct a program, a psycological type test was conducted to 505 women and four preliminary programs were carried out focusing on self-esteem, understanding of one's own personality dynamics, efficient communication, positive emotion, social belongingness and expressions of feelings of unfinished business. For the final program, Jung's theory of psychological type(MBTI, Satir's family therapy approach and psychodrama were applied. An experimental and a control group were designed consisting 16 women for each group. The program was carried out for 6 weeks for the experimental group. The result of treatment were as follows: 1) There was a difference statistically in LQ related to family harmony, serif-achievement and improvement of relationship with in-laws. 2) There was a statistical change in psychological factors of expression of feelings, self-esttem, communication, and positive emotions. 3) The program participants self reports indicate that the program was effective for the reconstruction of family relationship, self-understanding, group coherence, and instigation of hope. The reports also shows that the program was effective for the perceptual changes in parent-child, wife-husband and siblings' relationships. In conclusion, the program developed for the enhancement of Korean married women's life quality(LQ) based on the Jung's psychological type theory, Satir's family therapy approach and psychodrama was erective for the improvement of LQ.

This study has been done to review the historical development of the cataloging system of books with emphasis on those in England and the U. S. The findings can be summarized as follows: (1) In 1844, Sir Panizzi invented what seems to be the first of its kind in history to list the inventory systematically at the British Museum. It is believed to be a complete system consisting of 91 articles. (2) A comparatively systematic system was developed in America by Jewett. in 1852. Composed of only 39 articles, the system is considered a renovative one worked out with due regard to the infrastructure of a library. (3) In 1876, a classic system based on a lexicographical order was set up by Cutter. Rated as the best one that was designed by an individual, the theory has since exercised widespreading effects on cataloging. (4) American and British library scientists collaborated in printing several editions of numerous volumes on the principles of classification, but they are not believed fully successful in establishing a consistent and compressive system. Their efforts found significance rather in their being the first international collaboration and setting a foundation upon which the international system of today has been developed. (5) The ALA Rule, published concurrently in ALA and LC in 1949, had two parts in its classification, the list of authors and that of titles. Its scientific classification has completed the cataloging of books in its developmental stage. (6) The 1967 American-British Rules integrated the cataloging systems published under separate covers by authors and titles. The system as well as the 1961 Paris System has greatly contributed to the standardization of bibliographical description throughout the English-speaking countries. The International Standard Book Description standardized Bibliographic system has enabled the librarians in different countries to exchange their bibliographical sources easily, helped to overcome the language barrier in listing and contributed to the efficient reading of bibliographical records through machines. (7) The second edition of the Angelo-American cataloging Rules, promulgated in 1978 under the influence of the international standard bibliographical description, was the one in which all the previous Rules were revised to have their strong points. The adoption of punctuation system to employ the computerized data processing and the standardization of description are expected to improve the cataloging system not only in the English speaking countries but in the Universal Bibliographic Control as well.

This study made fundamental approaches on the significance of social enterprises on minority protection policies. In particular, it offered discussions focused on the relationship between social enterprises and North Korean defectors which greatly affect minority policies. Study results can be summed up as follows. First, the greatest difficulties for North Korean defectors in their adjustment to Korean society are economic activities and a sense of social differences and social enterprises are a policy which can resolve these problems in the most effective way. Second, existing social enterprises were excessively run by the central government and they were support models which lacked creativity and development. To resolve such problems, a lesson was learned that these must change into policy models with local coproduction. Third, a lesson was learned that social enterprises offer more than simple economic activity, offering the proper functions of society, culture, living, and language, and thus the participation of North Korean defectors in social enterprises should be made mandatory in certain sectors. Such research results will contribute to theoretically explaining the relationship between North Korean defectors and social enterprises as minority policies.

What matters in the society of knowledge and information is not that they just know certain facts, but that when faced with new situations, they should be able to develop novel ideas, apply them and do the problems or the tasks confronting them. This cannot be achieved through learning of mere knowledge. Computer programming lessons have shown positive effects on general thinking ability, metacognitive aspects, and logical thinking. The ACM has suggested that 8th grade students at the first level (second year students of middle school) be educated in programming languages such as LOGO to raise their ability to think logically. Previous studies have confirmed educational programming languages such as LOGO and BASIC, which are currently used, are helpful in improving the ability to think logically and to solve problems. However these languages lack connectivity with later learning. Little research has been done on 'Dolittle', an educational programming language, newly developed, using object-oriented notions. Few studies have been made of the effects of 'Dolittle' on the ability to think logically. The following results were obtained. The research didn't lead to a statistically significant improvement of the students' cognitive development level. However, proportional logic and combinational logic, among the six subcategories of logic, improved through the introduction of 'Dolittle' programming lessons. This leads to the conclusion that in the processing of solving the problems given, the students learned by themselves and improved their ability to think logically.
