The dental care delivery system and the dental specialty system have a very close relationship each other. Compared to Korea. Western European countries with predominant public sector in dental service have recognized merely 2 or 3 dental specialties, while North American countries with predominant private sector, 8 or 9 ones. It is desirable to adopt the dental specialty system as soon as possible in Korea to encourage scientific development in various dental specialties and qualitative advance in dental service. We, however, have to establish equitable dental care delivery system which can use limited dental resources efficiently as follows. 1. clarifying the different roles in assignments between general dentists and specialists by the amendment of the related laws such as the Medical Act and establishing the organic patient-referral system. 2. adopting the dental specialty system and expanding personnel and equipments so that the dental college hospitals, especially dental divisions of general hospitals, night function as secondary care facilities with specialties. 3. determining the size of dental specialists according to the national needs for dental specialized service's, whose number is to be not more than 10% of the total dentists. 4. transferring the function of accredating dental specialists to the efficient, self-controlled professional organization such as the Korean Dental Association rather than putting it under the governmental control. 5. conducting a comprehensive review of specialty education and practice for re-recognition, and maintaining competence of specialists by re-accredating them periodically. I expect this article to contribute to further discussion about the dental specialty system in Korea in productive and practical way. I am sure that we can Establish this system in the near future when people in every walks of life-the academic circle, the press, the authority concerned, consumer groups and the Korean Dental Association-take part in the discussion with special concern.

The objective of this study has two folds. The first is to investigate current global certification system and the second is to suggest some possible solutions for expanding global e-trade networks. Both research and industrial communities recognize the importance of global certification problems in connection with global e-trade payment because global e-trade volume continue to grow. But not many research results have been reported to the communities in identifying some barriers against active global certification systems. This paper intents to suggest some possible solutions for improved global certification system and the results are summarized as follows: First, strict certification structure has to be relaxed by considering diverse mutual certification methods in global e-trade practice. This paper provides some comparative results about mutual certification methods among different nations. Second, numerous business models have to be derived such that they can be applied to other global certification applications than global e-trade. Third, global certified networks have to be expanded beyond mutual certification level. Once the certified structure among different nations have been established then diverse certified authority channels have to be implemented. Finally, since Korea has already established very good public certification infrastructure within the nation this platform has to be positioned in the center of global e-trade networks. This paper has of course to accept a critique such as this study provided limited results to generalized global e-trade certification model, and therefore empirical study for assessing robust model should be pursued in the future.

This study examines work and family life of married women employed in a manufacturing industry. Data were gathered from the use of fact-to-face interview method from a sample of 230 married working women. The major findings of this study can be summarized as follows : (1) With high rates of change of job, most of the respondents remain unstable in their working situation. It was shown that the important factors influencing job satisfaction of married women are women's life cycle, degree of contribution of wife's income toward total family income, and husband's attitude toward wife's empolyment. The degree of job satisfaction is also strongly influenced by labor structural factors such as pay, work environment and fringe benefits. (2) The amount of household labor time was limited by job-related factors rather than by family-related factors, because among these working women employment itself is necessarily for their subsistance. (3) It was shown that wives participated more actively in their marital communications than their husbands. Most of the respondents showed the syncratic type of the decision making patterns, but this results does not necessarily mean wives exercised an equal power with their husbands. The economic factors and the emotional instability of the husband are the ones mostly influencing marital conflicts of the employed women. It was found that the respondents easily revealed marital conflicts related to personal problems of their husbands(such as extramarital affairs, gambling and alchoholism). However, they tried to overcome the structural conflicts related to authoritarian attitudes of their husbands or economic problems without any complaints. (4) Mothers have difficulty in controlling their adolescent children, due to the weakening of parental authority. Although most of the respondents perceived their employment as having negative impacts on their children, they still have high expectations toward their children. Inspite of low degree of father role expectations and facther role performance of their husbands, most of the respondents anticipated expressive roles as well as traditionally instrumental role from their husbands. Finally, these findings would help us determine family welfare policies in Korea. Improvements in paid and household labor structure of married women should be accomplished at the national level. Also, the acting programs for parent education, marital councelling services, and law enforcement for equal employment between men and women should be provided in our society.

Korea has kept its records of astronomical phenomena since around 2,000 years ago. However, the contents and scope of relevant service have been limited for researchers who need those records due to lack of complete data collection. In this regard, it is necessary to establish efficient collection and management systems of Korean astronomical records by utilizing an environment that is easily accessible. This study is intended to complete the development of a testbed system that allows researchers to systematically input and validate, in a Web environment, multiple astronomical records among the historical documents until Modern Joseon after the Three Kingdoms Period. Recognition of the pre-translated data and tables in advance is followed by its storage in the database built on the Web. Then, data validation is implemented by providing a retrieval service according to a specific form to only a finite number of researchers who have access authority. This study is targeted at a testbed system that takes around three months to be completely developed. The completed testbed system is expected to allow internal and external researchers of an organization to easily access the service on the Web. This will ensure that the accuracy of the data can be verified mutually and help identify areas of service improvement. The opinions collected regarding service improvement will be reflected in the future system. Eventually, domestic astronomical records will subsequently be able to be utilized internationally through the multilingual service.

In urban cities, buildings were built in the neighborhood, these buildings influence each other through structure-soilstructure interaction (SSSI) and seismic pounding due to limited separation distance in-between. Generally, the effects of the interaction between soil and structure are disregarded during seismic design and analysis of superstructure. However, the system of soil-base adversely changes structural behavior and response demands. Thus, the vibration characteristics plus the seismic response of a building are not able to be independent of those in adjacent buildings. The interaction between structure, soil, and structure investigates the action of the attendance of adjacent buildings to the others by the interaction effect of the sub-soil under dynamic disturbances. The main purpose of this research is to analyze the effects of SSSI and seismic pounding on the behavior of adjacent buildings. The response of a single structure or two adjacent structures with shallow raft base lying on soft soil are studied. Three dimensions finite element models are developed to investigate the effects of pounding; gap distance; conditions of soil; stories number; a mass of adjacent building and ground excitation frequency on the seismic responses and vibration characteristics of the structures. The variation in the story displacement, story shear, and story moment responses demands are studied to evaluate the presence effect of the adjacent buildings. Numerical results acquired using conditions of soil models are compared with the condition of fixed support and adjacent building models to a single building model. The peak responses of story displacement, story moment, and story shear are studied.

모바일 Ad-hoc 네트워크는 인프라에 관계없이 동작하고 제3의 신뢰기관 없이 운용되어야 한다. 또한 네트워크 크기, 노드 이동성, 기기의 배터리 용량 및 메모리 크기 등에 의하여 구현상 제약을 받는다. 그럼에도 불구하고 유선 네트워크처럼 인증, 기밀성, 무결성, 부인방지, 접근통제, 그리고 가용성 등 보안문제에 대한 고려가 필요하다. 특히, 이러한 보안문제들 중에서 인증은 네트워크 특성에 상당한 영향을 받기 때문에 본 논문에서는 인증에 초점을 맞추었다. 본 논문은 Hamming Distance의 개념을 도입하여 모바일 Ad-hoc 네트워크에서 공개키 인증서 생성 갱신 폐지 등 공개키 인증서 관리를 위한 프로토콜 및 공개키 인증서 검증을 위한 경로구축 알고리즘을 제안하고 그 성능을 평가한다. 본 논문에서 제안하는 경로구축 알고리즘은 각 노드의 공개키 인증서 저장소 크기를 $log_2N$보다 작아도 공개키 인증서 경로구축이 가능하도록 하였다.
