It is well observed in the satellite telecommunication policy of several States that legal constraints imposed upon the service coverage of satellite telecommunication as well as broadcasting are to be relaxed in a progressive way. Major aspects of such policy change lie in the adoption of policy refusing traditional concept of national frontier. In the case of direct broadcasting satellite service, while a debate upon the legal issues regarding the spill-over effect of that service is no more major concern of the States, many multinational enterprises are looking for strategic alliance for regional or global DBS project. On the other hand, an implementation plan for connecting the world through global mobile personal communication satellite system is being pursued by several joint effort of multinational firms. Legal issues arise regarding the regulatory competence of each State, Especially, a controversial issue is concerning the sovereign right well recognized upon the regulation of telecommunication. This study is focusing upon the evolution of such policy change for the purpose of allowing us to expect future develpment of worldwide satellite telecommunication policy environment.

The paper is to study and analyze the major issues and current problems of space law and policy to suggest the direction of Korean aerospace policy for future development facing the 21st century of air and space industry. It briefs the development of aerospace science and space law. It also outlines the special characteristics and present status of space law. It further reviews the regulatory regime of commercial space carriers, international telecommunication satelite and space environmental problems. Finally, it suggests the future directions of Korean space policy to develop as one of leading space countries in the 21st century.

Since Component-Based Development, or CBD, struck Korea SI industry a heavy blow several years ago, many major SI companies in Korea have implemented the CBD practices in real world, leveraging supports from the government and academic world. The result, however, falls short of their expectations. The major reason is that they have mainly focused on CBD processes and technical issues around it, although it is necessary as well to deal with other non-technical issues in order to make business values from CBD. This paper begins with reminding us what CBD tries to achieve indeed in terms of software development processes, then recognizes what we have achieved so far introducing a recent CBD project case, BOK-WIRE system. Thereafter, it reveals the chances that SI companies must take in order to make their CBD efforts succeed, pointing out what are the roadblocks really.

Digital trade rules are crucial in supporting the digital economy as the rules effectively reduce unnecessary trade barriers. This study introduces various approaches that major countries take regarding digital trade policies and rules. Comprehensive and Progressive Agreement for Trans-Pacific Partnership has introduced comprehensive rules on e-commerce, including binding articles on the free flow of information, location of computing facilities, and source code. More recent e-commerce provisions or digital trade agreements cover wider range of issues, from cyber security, artificial intelligence, and data innovation to electronic invoicing and payments. Multilateral negotiations on digital trade rules, including the World Trade Organization E-commerce Joint Statement Initiatives and Indo-Pacific Economic Framework, are in progress. Thus, countries involved are expected to respond to new digital trade issues with long-term strategies considering domestic policy objectives.

본 논문에서는 대형 사고나 자연재해 등 외상적 사건 발생 후 초기의 심리적 중재방법 중의 하나로 제공되어온 심리적 경험보고(psychological debriefing)의 대표적 모델들에 대해 소개하고, 그 효과에 대한 논란들에 대해 살펴보았다. 심리적 경험보고의 효과에 대해서는 기존의 경험적 연구들을 바탕으로 일관된 결론을 이끌어 내기가 어렵다. 현재로서는 CISD 등의 기법들에 대해 지적되어온 관련 문제들을 고찰하여 위기 현장에서 심리적 경험보고를 올바르게 사용하기 위한 방법을 모색하는 것이 중요하며, 논의 부분에 이를 제시하였다.

This paper gives reviews on current research status in telecommunication network design. Two problems are identified as major research issues. One is the WDM network design problem, where traffic grooming, virtual topology design and routing and wavelength assignment problems are considered. The other is the OSPF weight setting problem which was proposed as a practical method to implement traffic engineering capability in IP networks. After presenting surveys on those problems, we discuss potential challenging research issues in telecommunication network design.

Survey has been made to evaluate technological level and to identify research issues in CAD/CAM area. It is found out that major users of the CAD/CAM system are in mechanical and electronics as well as garment industries. Their experience shows that the impact of the CAD/CAM introduction is not yet noticeable in drafting man power and cost reduction. It is identified that the low penetration rate of CAD/CAM technology in industry is due to the lack of locally developed CAD/CAM softwares.

Urban transit is defined as "Transportation facilities and carriage by track like railway where is constructed and operated in urban area" in Korean urban railway law. Several hundreds of urban transits are operated in the world, and Korea also has 19 lines 590km in several cities like Seoul, Busan etc. In this paper, we classify urban transits and describe the general characteristics of urban transit. And then review major technical issues and present the direction to technical progress.

Electrostatic Discharge(ESD) is one of the major reliability, issues for today's VLSI production. Since the gate oxide with a thickness of 100~300$\AA$ is vulnerable to several thousand volt of ESD surge, it is necessary to control the ESD events and design an efficient protection circuit. In this paper, physical mechanism of the catastrophic ESD damage is investigated by transient analysis based upon Human Body Model(HBM). Using two-dimensional electrothermal simulator, we study the failure mechanism of the output protection devices by ESD and discuss the design issues for the optimun protection network.
