Climate changes and environmental pollution recently became a matter of global interest. Korean government established low carbon green growth act in the light of international environment regulation and started demonstration certificate project for GMS (Green Management System). We aim to explore audit data resulted from demonstration companies that pursued the GMS certificate. The demonstration companies are consisted of 11 companies that a certification body L gave the certificate. The audit data results were formed by minor nonconformities detected in the field evaluation based on GMS standards, KS I 7001/2 : 2011. We found out significant differences for minor nonconformities between types of industry and between major clauses of Part 1 and Part 2 in GMS standards. We make an effort to figure out the implication of causes of the significant differences. These results are expected to contribute to understand GMS operation situations and are utilized as a reference for energy management, social responsibility, and green gas reduction.

인증을 지원하고 비밀통신 설정을 위한 안전한 수단을 제공하기 위해 보편적으로 이용하고 있는 것이 X.509 v3 인증서를 이용하는 SSL/TLS 프로토콜이다. X.509 PKI는 아주 복잡하고도 불완전하기 때문에 이를 보완하기 위한 연구의 결과로 SPKI/SDSI가 탄생하였다. 본 논문은 기존의 Geronimo 프로젝트로 구현된 SPKI/SDSI 서버가 지니지 못한 비밀통신과 역할기반 접근제어 기능을 수행하는 보안모듈들을 추가하고, 온라인으로 이름&권한-인증서를 전담해 발행하는 이름&권한 위임 모듈을 탑재한 보안서버를 설계하며 그의 프로토타입을 구현함이 목적이다. 그리고 이 프로토타입의 구현이 웹상에서 어떻게 적용되는지를 실제 예를 통해 보였다.

The scope of this study is the construction conformity assessment system according to the new paradigm of construction management To minimize the differences between domestic and international state, construction Conformity Assessment is subdivided into system certification and product certification. For the former, WASCON(Worldwide Assessment System of Construction Quality Maturity Stage) is applied. For the latter, AQUA(Advanced Quality Assessment System) was developed and adopted to model project for demonstration. Both systems are designed to enable quantified rating, integrated into PQCS(Project Quality Certification), which is an advanced project quality certification system. The construction work observing PQCS will gain quality score on its own quality certificate(Quality mark on construction itself or facilities is also available, if needed or preferred by customers). This Quality Rating System will inspire and encourage any related parties. PQCS score would let supplier/constructor recognize how much themselves are operating effectively and efficiently, offering them the opportunity of redeeming their weaknesses.

The project to utilize kenaf as thermal power plant fuel has a positive effect on the unused energy utilization, greenhouse gas reduction, and farm income. However, it is analyzed that it is difficult to secure economical efficiency because the fuel cost of kenaf is higher than that of power by thermal power plant and Renewable Energy Certification (REC). The project of power generation using kenaf is meet the government's major policies, while government support is essential for securing economical efficiency. As a result of the sensitivity analysis on the ratio of the government subsidies, to secure economical efficiency, the power generation prices using kenaf through the direct financial support of the government indicate that 47% and 76% of kenaf fuel cost are supported by government in case of the Saemangeum reclamation and Gangneung-si, respectively. In the case of the government indirect policy support, if kenaf is included as a renewable energy source of Renewable Energy Portfolio Standard and REC is granted, the economic efficiency of Saemangeum reclamation and Gangneung-si is obtained when REC secured at 1.05 or more and 2.43 or more, respectively. The results of this study are meaningful in that the direct and indirect effects of the government on the development of the herbaceous energy crop, kenaf, were evaluated economically. These results are to suggest the need for demonstration study, but economics analyze and evaluate are necessary based on operational data through the demonstration phase in the future.

Purpose: The purpose of this study to assess long-term care facilities in Seoul and certificate Seoul-type elderly care facilities. After certification, Seoul city can provide certificated facilities with budget and support to improve service quality. Methods: Questionnaires to elderly care facilities experts and field surveys to facilities in Seoul have been conducted for the data collection. Results: The result of this study can be summarized into three points. The first one is that a direction of operation for Seoul-type elderly care facilities is to improve manpower and provide special program for enforcing quality assurance. The second one is that this study provide index of evaluation for Seoul-type elderly care facilities. The indexes include management, facility environment and safety, service delivery process, and service results. The third one is that management plan for this policy should be carried out. The management plan include demonstration project, opinion research. Implications: Seoul-type elderly care facilities can have positive effects on quality of service. For the introduction of this policy, Seoul city and autonomous Gu have to make careful preparations for this policy.
