Through 'The Renewable Energy 3020 Implementation Plan' for carbon neutrality, the government promised to raise the proportion of renewable energy generation to 20% and renewable energy installation capacity to 63.8% by 2030. Therefore, we plan to test a 5.5 MW offshore wind turbine near Maldo, Gunsan. In this project, we measure the level of public acceptance and perform ordinary least squares (OLS) regression analysis to show the determinants of public acceptance. The regression results are as followed. First, it is judged that the closer the distance to the offshore wind turbine, the more the economic effects considered by residents. Second, especially in Maldo, the experience of being discriminated from the Saemangeum project, is understood to have caused distrust in the surrounding fishing villages chief/Fisheries Cooperatives, converted into a local community effect. Finally, the policy implications are as follows. First, a bottom-up problem-solving method is required to improve public acceptance, based on the Living Lab. Second, the island community may be indifferent to the briefings or forums of outsiders. Therefore, a gradual approach is required through (in)formal channels based on reliability from a long-term perspective with nearby universities and research institutes using SamsØ Energy Academy.

Technology innovation companies are focusing on contributing to business performance by R&D project as a strategic tool. Successful R&D leads to corporate competitiveness enhancement, national industrial development, but there are high uncertainty and risks in R&D. Public and private R&D projects are carried out to achieve various purposes. It was verified how the risk management and benefit management of the R&D project affect the detailed R&D project performance between the Public and private domain. The impact of Project Leadership on R&D performance was also analyzed. Those who have participated in the Public and Private R&D projects at companies or research institutes were surveyed. First, it was found that project risk and benefit management have partially an effect on R&D project performance. Second, Public and private R&D Project Leadership showed partially a interaction effect between project management and project performance.

The purpose of the present study was to identify the charateristics and social activities of graduates from a School of Public Health in Seoul and to provide basic information which might contribute to the improvement of new established Schools of Public Health in Korea. The Subjects were composed of 199 persons who graduated from a School of Public Health in Seoul during the period of 1987 through 1989. The response rate was 59.8% (199 graduates). The survey was conducted from December 1st 1991 to the end of February 1992 with a self-administered questionnaire by mail. Descriptive analysis with Chi-square test was employed for analysis. The major results were as follows : 1. 462% of students were the group aged 24-28 and 76.5% of them were married at the time of entrance to the School. 2. The major motives to come to the School were continuous study in a graduate school(41.2%), and strengthening of job opportunities(35.3%). 3. The major expectation of students were to acquire new professional knowledge(31.9%), to improve present work performance(22.7%) and to become an educator(22.7%). 4. 84.9% of students had some kinds of expectation at the entrance to the School, but only 48.8% of them met their expectations they had had. 5. The most preferred subjects were Health Statistics and Epidemiology in order. 6. 59.7% of students insisted that a professor should advise 4-5 students in maximum for a thesis. 7. Students suggested that the candidate for scholarship should he selected from those who had earned high credits in the previous semester(33.6%), who were low economic status(31.l%) or who were recommended by academic adviser(24.4%). 8. 57.1% of students were positive in utilizing their major subjects studied in their current works. 9. Students expressed that if the School of Public Health is to be further developed full-time professors should be added (37.9%) and excellent students be secured (33.6%). 10. After graduation from the school, some of the respondents changed their job placement, the number of persons working in research institutes increased from 6 to 14 persons, those working in educational institutes from 16 to 35, and Ministry of Health and Social Affairs and its affiliated organization from 10 to 13.

정보화 사회가 도래하면서 정보보호의 중요성이 강조되고 있으며, 정보보호 서비스를 제공하기 위한 기반 구조로써 공개키 기반 구조가 구축되어 사용되고 있다. 공개키 기반 구조는 공개키 암호 방식을 사용하는 암호시스템에서 사용자의 공개키를 안전하고 신뢰성 있게 관리하는 수단을 제공한다. 그러나 사용자들의 개인키에 대한 관리 기술은 미비한 실정이다. 최근들어 암호 프로토콜을 이용하여 개인키를 안전하게 관리하기 위한 개인키 관리(PKM; Public Key Management) 프로토콜이 연구되고 있다. 이에 본 논문에서는 공개키 암호 기술에서 사용되는 개인키를 안전하게 관리하고, 키로밍 서비스를 제공할 수 있는 새로운 PKM 프로토콜을 제안하였다.

본 논문에서는 기존 서버 원격관리 시스템이 안고있던 보안상의 문제점을 최근에 보안 인프라로써 각광을 받고 있는 PKI(Public Key Infrastructure)를 사용한 원격 통합 서버관리 시스템을 제안하고자 한다. 통합 인증서버는 관리자의 인증을 SCVP를 사용해서 검증하며, SSL(Secure Socket Layer)을 통해서 데이터의 기밀성을 보장한다. 또한 제안된 시스템은 관리자가 다양한 종류의 플랫폼과 운영체제를 한번의 인증과정으로 원격에서 통합 관리가 가능한 SSO(Single-Sign On) 시스템이다.

공공기관은 자신의 정보시스템에 대한 보안 대책을 수립하기 위하여 자체 보안·분석평가를 수행함으로써 적절한 보안 목표와 방향을 설정해야 한다. 하지만, 현재 연구되어 있는 위험분석 및 보안평가방법론등은 복잡하고 전문적인 사항이 많으므로 자체 보안분석을 수행하기에는 인력 및 비용이 많이 소요된다. 이를 위하여 본 논문에서는 정보시스템의 위험분석방법론에서 제시하는 자산, 취약점, 위협, 대응책에 보안평가방법론을 포함하여 정보시스템에 대한 모델링, 가정, 증상, 원인, 해결책등을 통한 자가진단 보안 분석·평가 방법을 제시한다.

In this paper, we propose an efficient authentication protocol based on certificateless signature scheme, which does not need any infrastructure to deal with certification of public keys, among the vehicles in Vehicular Ad-hoc Networks. Moreover, the proposed protocol introduces the concept of interval signature key for efficiently solving the problem of certificate revocation.
