In this paper, we are introduced a certification system for open network environment. The Kerberos which was developed by MIT uses a secret key cryptosystem for authentication. It is secure and efficient for closed network users to authenticate each others. However, the kerberos has a disadvantage of managing a lot of secret keys for In this paper, we are introduced a certification system for open network environment. users in the open network environment. This paper suggests a method that uses X.509 to provide public keys with certification to Kerberos users for authentication in the X.500 directory standard. And we also suggest the smartcard as data storage device to enhance the security and availability.

This study basically aims to examine how the GBCC system, which has been implemented since 2005 regarding school facilities, is actually being applied to schools and to survey students' satisfaction and awareness of school facilities. Ultimately, this study is to contribute to improving environment-friendly certification indexes and promoting the system. When it comes to research methods, a school with the green building certification and a school without it were selected for comparison, the two schools were visited for the investigation of their actual conditions, and then, based on the results, a survey was conducted for the students of both schools on their satisfaction(POE) of the school facilities, and finally, the results of the two schools were compared with each other and analyzed. The results of this study shows that the facilities of the school with the green building certification are much superior to those of the school without the certification as well as the former has more various facilities then the latter Nonetheless, facilities with the green building certification were found to miss something in terms of maintenance and management. Most of the survey questions show that students of the school with green building certification have higher satisfaction and awareness levels for school facilities than those of the other school students without the certification. However, the difference was a merely relative one, with most students of the school with the certification answering "so so" for their school facilities in terms of absolute evaluation.

G-SEED has been introduced with the aim of reducing energy use and resources since 2002, as the system of certificating environmental friendliness of buildings to create comfortable environment. This study analyzed the changes of certification standard of G-SEED since the revision in 2016, comparing certification results of office buildings by grade, category and certification items between G-SEED 2013-2 version and revised version of 2016. Also, this study analyzed the average points and their standard deviation of certification items including both deleted items and newly added items and extracted items needed to be reviewed in the future revision. In the revision, G-SEED has been extended its certification system to involve existing buildings and Innovative Design categories newly introduced with revising the certification items and difficulties. In revised version of G-SEED, the certification grade appeared to change its acquisition ratio decreasing Green2 and increasing Green4, during Green1 and Green3 were similar in proportion. The average scores by categories appeared decrease in Energy and Environmental Pollution category and Materials and Resources category, on the other hand, Maintenance category appeared the highest increase in the average score. Otherwise, Land Use and Transportation, Water Circulation, Ecology, Indoor Environment categories appeared similar average scores both version of G-SEED. In addition, the Innovative Design which was newly introduced category, seems to expect gradual gaining high scores according to technology development in future, although its possession has shown lower scores in revised version.

보잉 737 맥스 사고사례에서 볼 수 있듯이 항공기 소프트웨어는 비중이 급속도로 증가하고 있으나 안전문제에서 취약한 것이 드러났다. 국내의 경우, 자체중량 150kg 이하 무인동력비행장치를 운용하려면 초경량비행장치 안전성인증이 요구되지만, 소프트웨어 인증 절차는 포함되지 않는다. 다만, 최근 무인동력비행장치의 활용이 증대됨에 따라 소프트웨어 검증이 요구되는 추세이다. 본 논문은 항공 소프트웨어 인증 규격인 DO-178C를 참조하여 무인동력비행장치에 적용할 수 있는 무인동력비행장치 소프트웨어 체크리스트를 제안하였다. 국내외 선진기업 및 기관에서 활용 중인 모델기반개발(Model-based Development) 기반의 헬리콥터 비행 제어 컴퓨터(FCC) 프로젝트에 제안된 체크리스트를 적용하는 사례연구를 수행하였다.

Until now, The Market of aviation parts had led by OEM(Original Equipment Manufacturer) parts because of aviation industry's nature required higher reliability and safety. But recently, The interest about PMA parts in aviation market is increasing continuously with various environmental changes, such as economic stagnation, oil price rise, development of the manufacture technique and newly rising market of Asia-Pacific region. So, this paper introduces the trend and the requirements of FAA PMA / EASA EPA in order to enhance understanding for certification for aviation parts.

교사는 교육의 성패를 좌우하는 중요한 요소이다. 따라서 대부분의 국가에서는 적정 수준의 자질과 전문성을 갖춘 교사를 학교 현장에 배치하기 위해서 교사 양성과 자격, 임용에 관한 사항을 제도적으로 규정하고 있다. 한국의 경우에는 법령에 의거 교사 자격증을 취득하고, 임용시험을 거쳐 학교에 배치한다. 반면에 미국의 경우 교사자격을 취득하기 위해서는 주교육부와 교사인증기관에서 Praxis 시험을 요구하고 있다. 한국의 교사 임용시험은 1차, 2차, 3차 시험으로 구성되어 있고, 그 중 1차 시험은 교과 전공 지식을 평가한다. 반면, 미국의 교사자격시험인 Praxis는 I, II, III로 구성되어 있고, 그 중 Praxis II는 교과 지식과 교수-학습에 관한 지식과 기능을 평가한다. 본 연구에는 한국과 미국의 사서교사를 위한 자격, 임용 제도를 고찰하고, 한국과 미국의 객관식 시험 문항을 비교 분석하여 발전방안을 모색하였다.

최근 클라우드에 대한 인식이 널리 확산되면서 세계적으로 클라우드 이용이 점점 더 증가하고 있다. 클라우드는 ICT를 기반으로 하는 다양한 산업에 융 복합이 가능하고, 비용 절감 등 장점이 많아 경기 침체기인 요즘 더욱더 각광받고 있다. 그러나 클라우드 서비스의 잠재력을 더욱 더 발휘하기 위해서는 서비스 제공자와 소비자관점에서 서비스의 보안, 성능, 가용성 등 핵심 이슈들에 대한 명확한 이해가 필요하며 사용자의 주된 관심은 어떻게 안전하고 신뢰할 수 있는 클라우드 서비스를 제공받아 사용할 것인가에 맞추어지게 된다. 이러한 문제점에 대응하기 위하여 한국에서는 클라우드 서비스 인증제도가 시행되고 있으며 일본에서는 ASP-SaaS-Cloud 인증제도가 시행되고 있다. 본 연구에서는 양국의 두 인증제도의 비교분석을 수행하고 두 인증제도간의 차이점에 대하여 기술한다. 궁극적으로는 두 인증제도간의 비교연구 결과를 토대로 한국의 클라우드 서비스 인증제도의 발전방안을 제안하기로 한다.

This study purposes to present the improvement on the index by analyzing concretely the certification and evaluation index and the actual certification acquisition focusing on the buildings acquiring the barrier-free (BF) certification. So, after analyzing the screening results of the buildings acquiring the BF certification and then grasping the general application level based on the above analysis, this study tries to present the improvement on the BF certification index by analyzing the detailed applications of the BF certification-acquired buildings and then grasping the problems on the evaluation index of the current certification system. It was analyzed that the items which applied the BF construction method generalized to the common buildings through the Act on the Promotion of Convenience in medium facilities and the items with higher distribution points were shown as high in terms of points and the acquired point level of items which influenced by the shape and condition of side and land to defile the appearance of buildings were low.

New and Renewable Energy Equipment Certification program has been integrated into the KS(Korean Industrial Standards) certification system as of July 29, 2015. This study is to determine whether the KS certification requirement has had a positive effect on corporate performance (e.g. quality improvement, financial result, customer satisfaction) within those that had already acquired the New and Renewable Energy Equipment KS certification. As a result, among the requirements for the KS certification, quality management, product management, and product testing have a positive impact on product quality improvement, and product testing has shown a positive influence on customer satisfaction. Although requisite for the KS certification did not have a significant effect on financial outcome such as increase in revenue, it has shown to have positive consequence to some extent on those firms that newly obtained the certification.
