The concentrations of polycyclic aromatic hydrocarbons (PAHs) and elemental carbon (EC) in particulate matter, typical primary aerosols have decreased in Seoul between 2003 and 2018 (80% for PAHs and 85% for EC). The yearly mean benzo[a]pyrene (BaP) concentration has been lower than 1 ng/m3 since 2010-2011, the target value set by the European Union (EU) and China. A series of policies related to solid fuel and vehicle in South Korea and China should be effective in the reduction of the ambient PAHs and EC concentrations. But the emission data of PAHs and EC at both countries did not support that hypothesis. Possible causes are uncertainties in the emission inventories of primary carbonaceous aerosols in South Korea and China, although there may be a minor effect of the emissions from North Korea on the concentrations in Seoul. Thus the further policy directions against PAHs and EC such as improvements of emissions inventories and measurements, intensive regulation of non-road mobile sources and control of PAHs derivatives are discussed.

Through the increment of requirement for EC(Electronic Commerce) oriented communication services, security multicast communications is becoming more important. However, multicast to EC environment is much different from unicast concept most network security protocols. On the network security, using mandatory access control of multilevel architecture which assigns a specific meaning to each subject, so we accomplish access control. In this way, access control security based on the information security level is proposed. A security protocol based on the architecture proposed in this paper would be utilized in security multicast communications, group key management service and leveled security service through multilevel EC security policy, Also we discuss and propose the security level scaleability and key management method on the network.

최근 국제기술환경은 국가 간 기술 개발 경쟁이 치열해지는 동시에 상호 협력도 확대되는 「경쟁」과 「협력」이 공존하는 상황이 전개되고 있다. 특히 세계의 1%에도 미치지 못하는 연구 개발 자원을 보유하고 있는 우리 나라의 경우, 인적·물적 자원의 한계를 극복하기 위해서는 「국제협력」에 적극 참여하는 것만이 유일한 번영의 길이라고 할 수 있다. 이러한 추세에 대응하여 과거 미국과 일본에 과도하게 의존되었던 기술 협력은 최근 EC, 소련, 동구권 등으로 다변화되고 있다. 향후 기술 협력의 추진 방향은 우리의 기술 개발 목표와 해외의 강점 분야를 연계한 쌍무협력을 강화하고, 국제 공동 연구에의 적극 참여와 지구적 문제의 해결에 능동적으로 동참하는 다국간 협력을 추진할 것으로 전망된다. 이하 미국, 일본, EC, 북한, 소련 및 북방 국가들과의 '92년도의 주요기술협력사항을 전망해본다.

Emerging digital economy, e-business, especially business to business(B2B) electronic commerce is understood one most single critical competitive weapon for organizations' global competitiveness. According to government white paper, Korea's electronic commerce records expansion stage in its volume and variety. Although Korea has remarkable EC records, still some differences are existed compare to the developed countries. IT in the developed countries, played an engine for the economic restructuring as well as for the economic growth. But in Korea, it's not fully utilized by the reasons of economic and noneconomic bottlenecks. Under the digital economic surroundings, EC or e-Business, is a business system to achieve the economic efficiency in the levels of an organization as well as a nation. So, we have to find the ways to utilize our EC infrastructure to contribute for the nation's global competitiveness. To find the way, this study recommends two types of policies, pull and push, beyond the OECD's suggestion, to government in order to expansion of EC, especially B2B EC.

There have been many research papers and practical implementations on the various EC(Electronic Commerce) aspects such as merchant system, security, payment gateway, legal and policy issues. However, it is very hard to find the systematic approaches and business process models from the viewpoint of the company willing to start B2C(Business-To-Customer) EC. Therefore, we develop business process models for the planning, systems analysis and design, implementation, and operation of internet shopping mall to suggest a guideline and reference model for the realization of successful B2C EC.

A Liner Conference can be defined as "a group of two or more vessel operating carriers which provide international liner services for the carriage of cargo on a particular route or routes within specific geographical limits and which has an agreement or arrangement within the framework of which they operate under uniform or common freight rates and any other agreed conditions with respect to the provisions of the liner services". This study reviews maritime transport policy regarding liner conference and the changes in the liner market over the decades. Liner shipping industry has long been protected from competition by block exemption. The repeal of the block exemption for liner conferences and the abolition of any special EC antitrust regime for the shipping industry marks an important step in European maritime competition policy. This article examines the origins and the rationale of the EC antitrust immunity granted so far th the shipping industry and explains the causes of this historic changes. The abolition of Regulation 4056/86 and of the EU commitment to the UN Code of Conduct marks an historical evolution in international maritime policy, which will have an influence far beyond the EU.

China is undertaking an energy reform from fossil fuels to clean energy to accomplish $CO_2$ intensity (CI) reduction commitments. After hydropower, nuclear energy is potential based on breadthwise comparison with the world and analysis of government energy consumption (EC) plan. This paper establishes a CI energy policy response forecasting model based on national and provincial EC plans. This model is then applied in Fujian Province to predict its CI from 2016 to 2020. The result shows that CI declines at a range of 43%-53% compared to that in 2005 considering five conditions of economic growth in 2020. Furthermore, Fujian will achieve the national goals in advance because EC is controlled and nuclear energy ratio increased to 16.4% (the proportion of non-fossil in primary energy is 26.7%). Finally, the development of nuclear energy in China and the world are analyzed, and several policies for energy optimization and CI reduction are proposed.
