이정기,노정희,홍성표,조애리,이준 조선대학교 전자정보통신연구소 2002 電子情報通信硏究所論文誌 Vol.5 No.2

인터넷이 인류사에 등장한 것은 지금으로부터 30년에 불과 하다. 인터넷은 개방성과 공개성 그리고 수평성을 지향한다. 이러한 특성을 기반으로 해서 인터넷은 디지털 경제를 구체화시키고 실현시키는 중요한 수단이 되고 있다. 현재 주목받고 있는 P2P(Peer-to-Peer)는 인터넷의 이러한 이상을 실현해 가는데 중요한 위치를 차지하고 있다. 개인과 개인간의 정보공유 모델인 P2P는 인터넷을 통해서 다른 사용자들과 정보를 주고받을 수 있는 기술을 말한다. 또한 컴퓨터 네트워크를 통해서 교환되는 정보의 양의 증가와 함께 네트워크의 보안성이 새로운 문제점으로 부각되고 있다. 네트웍에 있는 어떤 사용자가 제한하기 위해서공개된 환경에 있다고 가정하면, 각 사용자간에 허가받은 사용자에게만 접속을 는 서비스에 대한 요구를 인증 해야한다. 본 논문에서는 이를 해결하기 위해 P2P 환경에서 보안을 유지하는 방법을 제안하고, P2P 환경에서 안전하게 정보를 공유할 수 있는 메커니즘으로 Kerberos 인증 메커니즘을 인용하여 인증 메커니즘을 설계하였다. It is not more in 30 years from now that internet appears to history of man.Internet intends patency and patency and horizontal. According as progress by information society, computer network use and enlargement of scale are accelerated more. Also, with good physician increase of information that is exchanged through computer network, security of network is embossed to controversial point that is new. Because P2P as that remove or weakens center server function is open network that can participate between each user, problem about authentication between each users is risen. If certain user in network is in open environment, this user must authenticate request about service to user who is admitted between each user to limit connection. This treatise proposed method to keep security in P2P environment to solve this and designed certification mechanism that quote Kerberos certification mechanism to mechanism that can share information safety in P2P environment.

The purposes of this study were to suggest the feasible model and developmental directions of women's career education. Though career education in school has been continually developed, women's career education has been of little importance. In advanced countries, women's career education has been actively studied and performed to meet the need of ensuring nation's competitive manpower and the equity of educational opportunity. The model and developmental direction of women's career education should be established in a different way because women's educational experience are not same with those of men. Women's career education should be studied and developed in the context of socialization of sex role and sex discrimination in labor market. It has been known that many aspects of curriculum and teacher's in interaction with student are stereotyped in elementary and secondary education. In spite of women's increasing enrollment in higher education, they mainly enrolled in female-dominated majors that are less-marketable, less pay and status, in workplace. It is strongly need that more diverse studies on the career education for women should be performed and various vocational and career education and training programs and course for women must be developed and implemented. Furthermore, cooperative system among school. home, society, governmental institutions should be established.

To examine the effects of the welding residual stress on Mode I fatigue crack propagation behavior, 3mm thickness SS41 steel plate was welded by an Auto-matic Submerged Arc Welding. Initial residual stress and relaxation residual stresses according to each stress ratio were measured. The fatigue crack propagation behavior from the region of compressive residual stress to region of tensile residual stress was analyzed. The results predicted by the Forman's equation using the superposition approach of the respective stress intensity factors for the initial residual stress and for the applied stress according to each stress ratio were compared with experimental data. The validity of the superposition approach was investigated. The conclusion are summerized as follows: 1. When the component is subjected to a constant amplitude cyclic tensile loading, the welding residual stress is reduced as stress ratio increase. 2. As the fatigue crack is propagation through the compressive residual stress field, it was found that the effects of welding compressive residual stress on fatigue crack growth in weldments, and the stress ratio decreases, become larger and delay the fatigue crack growth rate. 3. For negative values of the effective stress ratio, R? in the welding compressive residual stress field, the prediction of fatigue crack growth rate by the Forman's equation were found to be corresponded to experimental data for stress ratio R?0.3, as the effective stress ratio R? approached zero, when the stress ratio R>0.3 the prediction of the fatigue crack growth rate by Forman's equation were found to be impossible.

ABSTRACTThe purpose of this study is to review the role of government in the current trends of vocational qualification system for building life learning society in Japan and to provide useful suggestions for the future directions to develop vocational qualification system in Korea.The vocational education and training system of Japan has been operated on the basis of ministry of education(Munbuso) and ministry of labor(Nodouso)is responsible for human resource development. But there has not been any partnerships between them to operate vocational education and training.Recently, Japan has been tried to actualize lifelong learning society at large. So ministry of education and ministry labor have supported and developed it's own vocational qualification system toward the lifelong learning society. In relation to that, they begin to take little partnerships and form a loose alliance. This is reason why lifelong learning society needs strong links between general and vocational education, vocational education and vocational training, learning and work.Nevertheless, Japan's dual vocational qualification system is limited for actualizing lifelong learning society. Korea's vocational education and training system and vocational qualification system are similar with those of Japan. So, it is necessary for us to understand the implications of the current trends of vocational qualification system in Japan to build and develop vocational qualification system toward lifelong learning society.

Polymerase chain reaction (PCR) is the most sensitive and rapid method for the diagnosis of M.tuberculosis infection. Many reports have shown different methods for mycobacterial DNA extraction, but revealed many differences in simplicity and time-consumption. We studied which method was the best among 7 different ones for DNA extraction from 32 smear-positive sputa, using PCR of targeting 123bp DNA fragment of IS6110. The methods were the following : SDS-Microwave oven method, NaOH Lysis method, Triton X-100, Proteinase K method, Lysis buffer method. SDS-Proteinase K method, Bead Beater method, and Bead Beater/CTAB method. The amplification products were identified by electrophoresis on ethidium bromide-stained agarose gels, and confirmed by restriction enzyme, Southern blot hybridization, and DNA sequencing. All 32 cases were positive (100%) by the 7 different methods. It took 1 hour or more to detect DNA in SDS-Microwave oven method, NaOH Lysis method, and Bead beater/CTAB method. It took 2 hours or less in the others. SDS-Proteinase K method and Bead Beater/CTAB method were simpler and more convinient than the others. These results suggest that SDS-Proteinase K method and Bead Beater/CTAB method might be better than the others for the extraction of mycobacterial DNA in terms of simplicity and time-consumption, although all the methods were sensitive.

This study has been made inverstigation for the difference of fatigue strength under variable cyclic-rate, compared with three types cyclic-rate, 2,700cmp and 100cpm using smooth specimens(K?=1.025) and center holed specimens(K?=2.02) of SCM440 steel were obtained through fatigue tests in the rotating. The following conclusions were obtained 1. The difference of fatigue strength under variable cycle-rate is large more the low stress amplitude level than high stress amplitude level. 2. The fatigue strength decrease with concentration factor increase, but the difference is comparatively decrease more than the concentration factor is high level. 3. According to decrease of the cyclic-rate, the failure time take long time. 4. The form of the fatigue crack propagation showed to the straight line according to increase of the cyclic-rate, and for the stress amplitude level, the final fracture surface located in the central part of specimens and large, and the fracture surface showed to the striation and dimple by the microscopic observation.

Objectives The purpose of this study was to examine the current situation and the limitations of the Mental Health Review Board and to identify the effectiveness of the community linkage for discharged patients. Methods The data was collected from the 116 patients who were discharged from August 2005 to July 2007 by the order of the Mental Health Review Board. The survey was conducted by telephone with using a structured questionnaire. Results 51 patients (44.0%) were able to be referred to community mental health services when they discharged. The readmission rate was 50.9% and the mean duration to the first readmission was 51.73 days (S.D.=103.5). The mean duration to the first readmission was significantly longer for the group that was referred to community services and that had a negative correlation with the stability of health security. The outpatient maintenance rate and the current admission status were also significantly different between the group that was referred to community services and the group that was not referred. Conclusion The activities of the mental health review board have definite limitations in Korea such as the high rate of immediate readmissions after the discharge orders. A hospital-community integrated service system could be one possible solution to improve the maintenance of mental health patients in the community and to prevent their readmission.

The assessment and recognition system of lifelong learning is a necessary element in constructing for lifelong learning system. It is important to increase visibility of learning which takes place outside formal education and actively recognize its results. Government has been tried to actualize the lifelong learning society through implementing the assessment and recognition system of lifelong learning like credit bank system, degree system of self-study, various vocational certification systems and so on. The purpose of this study is to analyze current status whether or not these systems are to ensure basic criteria for assessing and recognizing learning, and to provide developmental directions for the assessment and recognition system of lifelong learning in Korea. The assessment and recognition system of lifelong learning were reviewed on basis of assessing and recognizing criteria as purposes, standard, contents, methods, operating body, and transfer system. It is required to increase reliability, transferability, equity, efficiency, effectiveness, currency, validity of the assessment and recognition system of lifelong learning. Therefore government should strengthen the quality of systems, and develop design and strategies for promoting the utilization of lifelong learning outcomes in society at large.
