This study has aimed to compare an emission trading system (ETS) in the EU and Japan that introduced the scheme prior to Korea and provided the latter with a benchmarking model. Especially, the EU has a reputation for its well-organized and evolving system, and Japan has also successfully established the system despite its similar condition with Korea, such as an industrial structure and the degree of energy dependence. However, there are noticeable differences between the EU and Japan in their ETS. Whereas Japan has focused on securing certifications in CDM as the implementation of Kyoto protocol, EU has shown a tendency to transform the trading market from a parallel structure of EUA and CER transaction to only the EUA transaction after ending of 1st commitment period of the Kyoto Protocol. Since the differences were mainly caused by not only in a design of the system but also in internal governance and their national circumstance, it is meaningful to analyse the Korean case with a similar framework. This study may contribute to designing an appropriate system for emission trading in Korea through the comparison of the EU and Japanese case.

본 논문에서는 ICISC 2004에 제안된 status certificate-based encryption(SCBE) 기법과 EUC Workshops 2006에 제안된 certificateless signature(CLS) 기법의 취약성을 제시한다. 이 두 기법은 ID 기반 암호시스템이 가지는 키 위탁 성질을 없애기 위해 사용자와 관리서버(CA또는 KGC)가 함께 사용자 키(SCBE: 복호용 키, CLS: 서명용 키)를 생성하게 되어 있고, 이들 중 한쪽만을 제어할 수 있는 공격자는 암호시스템에 위해를 가할 수 있는 어떠한 이점도 가질 수 없다고 알려져 있다. 그러나, 본 논문에서는 각 기법의 공격모델에서 허용하는 공격자가 공개키 변조를 통해 독자적으로 사용자 키를 생성하여 사용할 수 있음을 보인다.

전자상거래 등 보안을 요구하는 정보보호 시스템 분야에서는 공개키 기반구조(PKI: Public Key Infrastructure)가 폭넓게 사용되고 있다. PKI 도메인들이 더 많이 설립될수록 더 많은 상호 인증을 필요로 하게 된다. 더구나 각국은 더욱 복잡한 상호 인증을 필요로 하는 많은 인증기관을 가지고 있다. 그러므로 상호 인증을 위한 경로 탐색시 가능한 인증 경로를 빨리 찾기 위한 알고리즘이 필요하다. 이것은 PKI 시스템이 커짐에 따라 더욱 필수 불가결한 요건이 될 것이다. 그러므로 본 논문에서는 그러한 요구에 따라 고속 인증 경로 탐색 알고리즘을 설계하고 구현하였으며 또한 설계된 시스템의 동작 특성을 조사하였다.

"Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Multi-housing residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling project is very unique in that building residents are selected prior to design phase. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.

Although interest in eco-friendly fashion products is increasing among scholars and industry leaders, the concept of eco-friendly products remains unclear, preventing consistent assessment of which fashion products are eco-friendly. This study conducted a content analysis of eco-friendly product information from 87 domestic and 102 foreign brands to reveal key standards for categorizing eco-friendly fashion products. Product characteristic information was coded according to the four material-based standards (i.e., organic material, regenerative material, alternative material, and sustainably produced/upcycled material). Consistency between coders was confirmed by Cohen's kappa. In results, eco-friendly fashion products are categorized by four material-based standards and two certification standards (i.e., certified, not certified). Among the four material-based categories, the greatest number of domestic and foreign companies produced eco-friendly products that were classified as the regenerative material group. In addition, companies acquired eco-friendly certifications related to the use of organic, regenerative, and alternative materials. The greatest number of eco-friendly material brands used for eco-friendly fashion products belonged to the regenerative material group. Based on the study results, a typology of eco-friendly products was suggested. This typology can benefit practitioners and academics by highlighting a need for classification system for the eco-friendly fashion products, as well as by providing insight into the categorization of eco-friendly fashion products.
