  • Russia's push in the Asia-Pacific region stems from its interests that have the national, regional and global dimensions. In their turn, the aims of this policy are civilizational, geopolitical, economic and prospective, with a long-term outlook. In the course of their achievement, cooperation with Northeast Asia's countries will play one of the key roles owing to the factors of geographic proximity, Northeast Asia's economic potential, risk hedging and a growing influence Northeast Asia exerts upon the global development. A new cooperation paradigm between Russia and the states of Northeast Asia should be based upon establishing and cementing self-reproducing ties. This is the central aim of Russian initiatives in relations, with Japan, the Republic of Korea, Democratic People's Republic of Korea, Mongolia and China. However, numerous obstacles ranging from Russia's absence in the regional free trade agreements and supply-production chains of value-added production to the permanent international instability generated by Pyongyang's missile-nuclear developments hamper the practical implementation of this task. Realizing the necessity to give an additional impetus to this new cooperative paradigm, Russia has to develop directions with an apparent consolidating effect. The most promising may be the establishment of a permanent security forum based upon Northeast Asia Peace and Security Mechanism chaired by the Russian Federation. The urgency of this measure and its expected support stem from the necessity to strengthen security in Northeast Asia, a task neither the US-led hub-and-spoke system nor ASE-AN-led multilateral dialogue venues have been able to resolve. The issues addressed at the security forum must include the unification of approaches to North Korean nuclear issue and producing a document specifying actions of the claimants on the disputed maritime territories in the "direct contact" situations. At the expert level, Russia has elaborated on the idea to establish such a forum outlining the spectrum of the key directions of cooperation. With the urgency in the establishment of this dialogue venue, its agenda has to be coordinated with the agendas of the existing security systems presented by the US alliances and the ASE-AN-led multilateral negotiations. The practical implementation of this initiative will strengthen security in Northeast Asia as its challenges will be resolved in the pre-emptive way based on coordinated approaches. Therefore, Russia as the Eurasian state will be one of the role players in the advent of the Asian century.

  • Kohnfelder는 1978년 그의 학사논문 'Towards a Practical Public-Key Cryptosystem'을 통해 처음으로 서명된 데이터구조 즉 믿을 수 있는 사람에게 공개키를 전달할 수 있는 인증서의 개념을 소개했다. 따라서 20년이 넘도록 이 개념은 무결성 관점에서 공개키를 필요한 사용자에게 전달하기 위해 필요한, 확장 가능하고 안전한 방식으로 인정받고 있다. 간단히 말하면, 공개키 인증서는 사용자의 이름이나 사용자와 연관된 어떤 특성을 사용자의 공개키와 연결하는데 사용된다. 현재 공개키 기반의 인증서는 인터넷뱅킹, 전자상거래 분야뿐만 아니라 개인 식별을 위해 주민등록번호 대신 사용되는 등 그 활용범위가 넓어지고 있다. 인증서가 만료되지 않았더라도 발급된 인증서가 더 이상 유효해서는 안 되는 경우가 있을 수 있다. 따라서 인증서가 유효기간이 종료되기 전에 공개키 인증서를 폐기할 수 있도록 효율적이면서 신뢰할 수 있는 방식이 필요하며, 이에 대한 다양한 방식이 제안되고 있다. 인증서 폐기는 PKI의 광범위한 사용에 따라 점차 중대한 문제가 되어가고 있다. 그러므로 본 논문에서는 지금까지 발표된 인증서 폐기 메커니즘 및 최근 동향에 대하여 분석하고자 한다. 분석하고자 한다.

  • There has been an impetus in the development of biocontrol agents (BCAs) with the removal of a number of chemical compounds in the market, especially in the European Union. This has been a major driver in the development of Integrated Pest Management systems (IPM) for both pest and disease control. For control of mycotoxigenic fungi, there is interest in both control of colonization and more importantly toxin contamination of staple food commodities. Thus the relative inoculum potential of biocontrol agent vs the toxigenic specie sis important. The major bottlenecks in the production and development of formulations of biocontrol agents are the resilience of the strains, inoculum quality and formulation with effective field efficacy. It was recently been shown for mycotoxigenic fungi such as Aspergillus flavus, under extreme climate change conditions, growth is not affected although there may be a stimulation of aflatoxin production. Thus, the development of resilient biocontrol strains which can may have conserved control efficacy but have the necessary resilience becomes critical form a food security point of view. Indeed, under predicted climate change scenarios the diversity of pests and fungal diseases are expected to have profound impacts on food security. Thus, when examining the identification of potential biocontrol strains, production and formulation it is critical that the resilience to CC environmental factors are included and quantified. The problems in relation to the physiological competence and the relative humidity range over which efficacy can occur, especially pre-harvest may be increase under climate change conditions. We have examined the efficacy of atoxigenic strains of A. flavus and Clanostachys rosea and other candidates for control of A. flavus and aflatoxin contamination of maize, and for Fusarium verticillioides and fumonisin toxin control. We have also examined the potential use of fluidized-bed drying, nanoparticles/nanospheres and encapsulation approaches to enhance the potential for the production of resilient biocontrol formulations. The objective being the delivery of biocontrol efficacy under extreme interacting climatic conditions. The potential impact of climate change factors on the efficacy of biocontrol of fungal diseases and mycotoxins are discussed.

  • During the ancient times, there was no separative judicial system and administrative , legislative and judiciary functions were ultimately concentrated in the all-powerful monarch. And the three states developed state organization , adopting hieratical structures and placing at the pinnacle . State Codes were promulgated to initiate a legal system to rule the people, these codes instituted under influence of China codes. The people tradition sees crime control as the preservation of the authority of hereditary rulers. In the period of the Koryeo dynasty, government accepted a serious of detailed penal code from Tang dynasty . Legal response to crime stressed preservation of the dynasty rather than making citizen behave according to certain rules. In the period of Early Joseon , the compilation of Grand Code for state administration was initiated, the Kyeongkuk Taejeon ,became comer stone of the dynastic administration and provided the monarchial system with a sort of constitutional law in written form. This national code was in portant means of criminal policy at that time, Late Joseon , the impact of Western culture entering through China gave further impetus to pragmatic studies which called for socio-economic reforms and readjustment. Approach to criminal justice policy emphasized more equitable operation of the criminal justice system ,rehabilitation and crime control. Korea-Japanese Treaty concluded on 22 August ,1910 and proclaim a week later ,Japan gave the coup de grace to the Korea Empire and changed the office of the Resident - General into the Government - General . Thus korean criminal policy were lost during a dark ages ,which lasted for 36 years after fall of Joseon Dynasty (the colnial period,1910${\sim}$1945). After 1945 Korea's liberation from Japanese colonial rule, the occupation of devided Korea by the United States and Soviet Union frustrated the efforts of Koreans to establish an independent government, and the transplantation of two conflicting political ideologies to south and the north of the 38th parallel further intensified the national split. U.S. military government office occupied the south of the 38 the parallel and placed emphasis on democracy of criminal policy. ln 1948, the U.S. military government handed over to the ROK government its administrative authority.

  • 본 논문은 인도네시아 발리 우붓 지역에 위치한 한 농촌마을에 대한 민족지이다. 뉴꾸닝 마을을 중심으로 관광발전에 따른 사회 문화적 전개 과정과 거주관광객의 문화적 실천방식을 고찰한다. 문화관광 발달에 있어 반자르의 역할 특히 전통 담론에 대한 재인식 과정은 마을 번영의 주요한 계기가 된다. 거주관광객을 중심으로 마을에 대한 요구, 이에 대응하는 현지주민의 역할에 대해 논의한다. 거주관광객과 주민집단은 한 공간에서 문화접변의 과정을 경험하고, 이는 각각의 집단이 전통에 대해 새롭게 인식하는 계기가 된다. 결국 거주관광객의 마을 거주는 기존의 객관적 구성주의적 고유성에 대한 개념에서 비롯된 대상물 중심의 관광실천에 대해 재고찰하는 계기가 된다. 거주관광객의 고유성에 대한 인식은 관광경험 과정에서 획득한 일상적인 만족과 안전에서 비롯된 존재론적 인식의 일부이다. 뉴꾸닝 마을이 관광지로 발전하는 과정은 거주관광객이 마을 전통을 실천하면서 획득하는 일종의 실존적 고유성의 관점에서 이해된다.
