분산 네트워크 환경의 보안에 있어서 인증(authentication)과 함께 허가(authorization)는 필수적인 보안 기능이다. 허가는 사용자나 과정이 특별한 운영을 수행할 것인지를 판단하고 결정하는 절차다. 본 논문에서는 인증 메커니즘은 기존 커버로스를 사용하고 효율적인 시스템을 만들기 위해 허가 메커니즘을 설계하여 첨가한다. 제안한 허가 메커니즘은 커버로스 서버 안에 프록시 권한 서버를 운영한다. 프록시 권한 서버는 제안한 알고리즘을 사용하여 자신이 속한 영역의 사용자, 서버 및 서비스의 권한을 관리하고 허가한다. 또한, 프록시 권한 서버가 발행하는 권한 속성 인증서는 권한 위임에 사용된다 기존의 커버로스의 인증 메커니즘에 제안하고 있는 효율적인 허가 메커니즘을 추가함으로써 보다 안전한 커버로스를 설계했다. Authentication and authorization are essential functions for the security of distributed network environment. Authorization is determining and to decide whether a user or process is permitted to perform a particular operation. In this paper, we design an authorization mechanism to make a system more effective with Kerberos for authentication mechanism. In the authorization mechanism, Kerberos server operates proxy privilege server. Proxy privilege server manages and permits right of users, servers and services with using proposed algorithm. Also, privilege attribute certificate issued by proxy privilege server is used in delegation. We designed secure kerberos with proposed functions for effective authorization at the same time authentication of Kerberos mechanism.

유엔해양법협약이 발효된 이후 20여년이 지났지만 황해 어업자원의 이용과 보존에 관한 문제는 여전히 해결되지 않고 있으며 효과적인 관리조치의 부재로 인해 어업자원이 심각하게 파괴되고 있다. 세계자연기금회(WWF)가 발표한 “해양경제진흥—2015년행동계획”에 따르면 황해생태구역은 세계적인 보존가치를 갖는 해역이나 해양자원의 훼손 및 파괴가 가장 빠른 속도로 진행되고 있는 지역의 하나로서 전 해역 90%의 어업자원이 상업어업에 의해 멸종되었다. 이러한 상황은 연구자로 하여금 기존의 국제법상 어업규범 특히, 황해지역에 적용되는 어업자원보존에 관한 법제도의 실효성과 타당성에 대해 의문을 갖게 하였고 이에 대한 재검토가 필요하다고 판단되었다. 주지하는 바와 같이 어업자원의 보존 및 관리조치는 자원의 지속가능한 이용을 위한 중요한 제도이다. 오랜 시간 동안 중국, 일본, 한국, 북한 등 주변국들은 황해 전통어장에서 공동으로 조업하여 왔으나 지나친 남획으로 인해 자원고갈이 심각한 상황이며 자원에 대한 효과적인 보존 및 관리가 이루어지지 않아 해양생태계가 심각하게 파괴되었다. 이에 따라 1990년대에 들어서 황해 어업자원은 쇠퇴기에 들어서게 되었고, 한중 어업협정의 체결에도 불구하고 중국불법어업이 근절되고 있지 않은 관계로 양국 간의 어업분쟁이 빈번히 발생하고 있다. 황해에서 중국의 지속적인 불법조업과 이에 대한 중국정부의 무책임한 태도는 자원의 보존과 관리를 더더욱 어렵게 하고 있는 실정이다. 본문은 황해어업자원의 이용과 보존에 관한 의제를 둘러싸고 관련 국가 간의 어업자원보존을 위한 협력관계의 발전과정, 어업자원보존 및 관리조치의 시행과 효과 및 문제점에 대해 분석하고 나아가 황해 어업자원보존을 위한 제도적 장치를 확보하기 위한 몇 가지 대응책을 제시하고자 한다. Although the convention on the law of the sea has implemented for more than 20 years, but the problems of fisheries resources in the Yellow Sea are more and more serious, the problems have not been effectively resolved. On May 6, 2015 the WWF pointed out in its “Reviving the Ocean Economy: The case for action – 2015” that the Yellow Sea ecosystem has global ecological protection value, but this area is one of the worst degradation of marine fisheries resources areas. About ninety percent of fisheries resources have been extinct by commercial fishing in the Yellow Sea – Bohai Sea. Facing the grim situation, we should question the existing international fishery law, especially on the applicable of the Yellow Sea fisheries conservation legal system protection question. It is necessary to review the conservation of fisheries resources. As we all know,the conservation and management of fisheries resources has become an inevitable trend of sustainable utilization of fisheries resources in the international community. The Yellow Sea was rich in resources with a healthy ecosystem, as a traditional fishing ground was jointly developed by China, South Korea Japan, North Korea and other neighboring countries. The Yellow Sea provides rich fishery resources and a strong support for the development of Fisheries Economy for the surrounding countries. Because of the overfishing, lacking effective conservation and management ecosystems have been severely damaged seriously. Since 1990s of the 20-century, the Yellow Sea's fisheries resources have begun to decline. Especially the current fisheries resources face to dry up, China’s neighboring countries more and more pay attention to protect maritime rights and interests. The conflict between China and its neighboring countries in the development of fisheries resources and the protection of the marine rights and interests is increasingly fierce, which brings many difficulties to the maintenance and management of fisheries resources in the Yellow Sea. In order to solve the problems that the utilization and conservation of fisheries resources in the Yellow Sea, this paper will focus on the problems existing in the utilization and protection of fisheries resources in the Yellow Sea and analyze the relationships of the coastal countries around the Yellow Sea. Study the international fisheries law and international practice analyze the international law and the domestic law in the conservation of the Yellow Sea fisheries resources in the existence of gains and losses. At last, some proposals were put forward that the suggestions on how to improve the protection law of the Yellow Sea fisheries resources.

In order to actively participate in global governance of climate change, Taiwan formulated and implemented the <Greenhouse Gas Reduction and Management Act> in 2015. The law stipulates that greenhouse gas emissions will be reduced to half of 2005 levels by 2050. The low setting of emission reduction target and the lack of effective emission reduction measures, as well as the lack of core legal systems such as climate change and just transition, have received widespread criticism, which to some extent affects the achievement of the national greenhouse gas emission reduction goal. Therefore, it is necessary to follow up and modify the law. Based on this, on January 10, 2023, the Legislature passed the third reading by renaming the Greenhouse Gas Reduction and Management Act to the Climate Change Response Act, strengthening greenhouse gas emission reduction target, improving policy adjustment mechanisms, and adding comprehensive climate change adaptation system, carbon fee system, and just transition policy to respond climate change. On September 24, 2021, South Korea <Framework Act On Carbon Neutrality And Green Growth For Coping With Climate Crisis>, which incorporated the goal of achieving carbon neutrality by 2050. In May 2021, the 2050 Presidential Commission on Carbon neutrality and Green Growth was established. In April 2023, the committee adopted the national strategy and the first national basic plan on “Achieving Carbon Neutrality And Green Development In 2050”. In this context, this study focuses on the analysis of the necessity and limitations of the amendment of Taiwan <Greenhouse Gas Mitigation and Management Act>. Through analyzing the process and the main contents of <Climate Change Response Act>, and several controversial issues, so as to provide a way to further improve South Korea <Carbon Neutrality Act>. The administrative procedure act of Taiwan was enacted in 1999, this law extensively refers to the Federal German administrative procedure act includes substantial legal regulations. Up to now this law has been revised five times, but there was only a tiny fraction of the law was been revised such as the executive ill-gotten gains refund litigation, administrative sanction, etc. This law had been challenged because of the limitation and practicability. The ministry of justice had received a new comprehensive amendment in 2016. The government department concerned is currently canvassing opinion. 대만은 국제사회 기후변화 대응에 적극 동참하고 온실가스 배출을 감축하기위해 2015년 「온실가스 감축·관리법」을 제정하여 시행하였으나 ‘2050년 2005 년 대비 온실가스 배출량 50% 감축’이라는 현저히 낮은 온실가스 감축목표 설정, 온실가스 배출량 감축을 위한 효과적인 정책수단의 부재, 기후변화 적응과정의로운 사회 전환 등 핵심 내용의 부재에 대한 비판이 이어짐에 따라 법률개정의 필요성이 제기되었다. 이에 따라 2023년 1월 10일 기존의 「온실가스감축·관리법」에서 「기후변화대응법」으로 명칭을 변경하고, 온실가스 감축목표 강화, 정책조정체계 보완, 기후변화 적응, 탄소요금, 정의로운 전환 등 종합적인 기후변화 대응을 위한 대응정책을 담은 법률안이 입법원에서 통과되었다. 한국은 2021년 9월 24일 2050년 탄소중립이라는 국가목표 실현을 위한 법정 절차와 정책수단을 담은 법률인 「탄소중립기본법」을 제정하여 시행하고, 2021년 5월에 대통령 직속 2050 탄소중립・녹색성장위원회를 출범하고, 2023년4월에는 ‘2050 탄소중립 달성과 녹색성장 실현’을 위한 국가 전략 및 제1차 국가 기본계획을 의결하는 등 기후변화 대응을 위해 보다 적극적인 정책을 펼치고 있다. 이와 같이 2020년 이후 새롭게 도래하는 신기후체제에 효과적으로대응하기 위해 대만과 한국은 새로운 입법적 조치들이 적극적으로 이루어지고있다는 점을 감안하여 본 연구는 대만 「온실가스 감축·관리법」 개정의 필요성과 한계에 대해 살펴보고 나아가 법률개정의 논의와 주요 내용, 개정법률의몇 가지 쟁점사항에 대해 체계적으로 분석함으로써 한국의 「탄소중립기본법」 의 개선 및 보완에 관한 문제해결의 실마리를 제공하고자 한다.

The eleventh meeting of the Twelfth NPCSC(Standing Committee of the National People's Congres) passed the decision on Amending the <Administrative Procedure Law Of The People's Republic of China> on November 1, 2014. It’s the first time to amend the Chinese Administrative Procedure Law of 24 years. It has been done major amendments in order to solve three difficult problems which are difficult to filing a case and judgment and enforcement, realize of the protection of the legitimate rights and interests of the administrative counterpart, increase the intensity of judicial trial, strengthen the supervision and control of administrative power, protect the right of appeal in administrative litigation, etc. It added a filing hierarchy expanded the scope of the case to solve the difficult problem of filing. It introduced centralized jurisdiction and hierarchical jurisdiction to solve the difficult problem of filing. In order to solve the difficult problem of filling the newly revised law prescribes the persons who are directly in charge and the other persons who are directly responsible, even allow to announce the situation when the administrative organ refuse to perform, etc. Research on the amending process of administrative procedure law we can know the theoretical circles and practical circles even common people focus on expanding the scope of the case. The scope of administrative litigation isn’t only relate to protecting the civil right and the specific scope of the judicial authorities examine the administrative organ whether to act according to law, but also directly affect the relationships between administrative organ, administrative counterpart and court. Therefore how to define the case scope of administrative litigation can help the court to trial correctly and promptly. Also protect and supervise the administration of the administrative organs according to law. It’s very valuable to protect the lawful rights and interests of a citizen, legal person. Before the amendment of the administrative procedure law is not wide enough, many disputes of lawsuit have not been included in the scope. Effective aids are difficult to achieve. So that administrative litigation gradually lose at energy. In the new administrative procedure law ‘The specific administrative act’ is changed to ‘Administrative act’. The scope of the protection of the civil rights is wider than before. In addition to the personal right and property rights, the social security right, fair competition right and the other rights are included in the scope.
