It has been more than 10 years since the river basin management system was introduced to Korea, and the research regarding that area is still at the beginning level. This study analyzes the problemof current river basinmanagement systemfocusing on Nakdong River and seeks improvement in order to extract the policy implication. Organizational structure, financial mean and regulation scheme for the river basin management were covered. Role of Nakdong River environmental office and River Basin Commission was discussed at the organization structure, the central government`s financial aid and operation of river management fund at the financial mean, control of land use and total pollutant loadmanagement systemat the regulation scheme. The flawof our river basinmanagement stems fromthe lack of understanding the environmental state of river basin and preparation before implementing the policy. There are three policy implications. Firstly, river environmental office must actually control the whole river areas by integrating organizations related to wide area river basin. Secondly, water management expenses should be shared in the framework of polluter`s pays principle and benefit principle, and the financial capability of local government should also be considered. Thirdly, a variety of land use regulation policies must be reflected on the citymanagement plan to attain a legal force.

본 논문에서는 물리, 화학, 생물 등 실험 교과목에 대하여 학생들이 가정 및 여러 장소에서 원격 접근 기능을 가지는 마이크로프로세서 기반 실험 장치( Microprocessor Based Laboratory Systems, MBL)의 소프트웨어 및 하드웨어 플랫폼 구조 설계에 관하여 연구 하였다. 본 시스템에서는 학교 실험실에서 수행되는 실험교과목에 대한 다양한 주변 환경 및 실험방법에 대하여 지원 가능하도록 원격접근기능을 TCP/IP 프로토콜로 구현한 NUTOS를 실시간 운영체제를 사용하였다. 본 논문에서 제안한 MBL-NUTOS(Microprocessor Based Laboratory-NUT/OS)는 실시간 인터넷 접속이 가능하며 서버 또는 클라이언트로 활용 가능하도록 설계 되었으며 실험을 통하여 본 플랫폼의 유용성을 입증하였다. 본 MBL 하드웨어 플랫폼에서는 기존의 마이크로프로세서 기반 실험 장치가 가지고 있지 않은 네트워크 접근 기능이 구현 되었으며 또한 실시간으로 실험 상황을 인터넷으로 억세스 할 수 있는 장점을 가지고 있다. 더욱이, 저비용 고집적도를 가지게 설계되어 일선 학교에서 용이 하게 사용 할 수 있도록 하였으며, 학교 실험실에서 수행되는 실험이 미래 유비쿼터스 교육환경에 적용 가능하도록 하여 첨단 과학에 대한 학생들의 인지를 넓히는 주요 매개체로서 그 교육 효과를 높이도록 하였다. The Microprocessor Based Laboratory Systems(MBL) with the remote access functional could put basic science experimental facilities together by providing a modern platform that the students can utilize simultaneously to learn basic physics, chemistry and biology. Our educator target platform combines a highly integrated 8-bit embedded Atmega128 processor and real time embedded OS (operating system), allowing plenty of headroom for follow-on basic science projects for students. The proposed MBL-NUTOS (Microprocessor Based Laboratory-NUT/OS) employed in the lab are available with internet base simulation capabilities, on public servers and students personal PCs, enabling the students to study at home and increasing the opportunity of accessing for the science laboratory facility.

Recently, environmental conflict over water resources among regions has much impacts on the economic growth and social order in South Korea. According to many studies in this field, principled negotiation among interest group has been recommended to solve the environmental conflict. Moreover, it is not yet devised what kinds of principles and methods of negotiation are effective to settle the conflict. This study investigates to the most equitable principle and method which seem to solve the environmental conflicts over water conservation and use among regions in South Korea through analyzing developing countries cases. The finding of this study are as follow; First, it is necessary to follow the Public Doctrine Theory to solve the water environmental conflict, because water resources are public goods, and also has to be distributed to all the peoples and all the generations. It means that coordinating powers of central government over water resources conflict has to be strengthened. Second, to settle water conflict, it needs to introduce and enlarge the Equitable Utilization Principle of common water resources. And also, to realize equitable cost division structure, we are devised to harmonize the Polluter Pays Principle with the Beneficiary Pays Principle. Third, as methods of negotiation, Interstate Compact and Regulatory Negotiation seem to be desirable to settle water resources conflicts in South Korea.
지리산 주요 활엽수종의 (闊葉樹種) 엽면적 (葉面積) 추정식에 대한 연구

This paper is concerned with estimating equations of leaf area(A) obtained from linear measurements - leaf length(L) and leaf width(W) - on the leaves of 13 species composing a natural mixed stand in Mt. Jiri. This method is known to be rapid and non-destructive in estimating leaf area. The equation of A=bLW is frequently used in rough and rapid estimation. Each species in this study has its own coefficient b according to its geometrical leaf shape. The range of coefficients of 13 species was 0.579 to 0.717. This means that the relationship A=2/3LW is suitable to most broad leaf species in a natural mixed stand in Mt. Jiri. When more precise estimation of leaf area is needed, full regression equation is used. In this study, the form of log A = b_0 + b₁ log LW was the most precise estimation equation in 8 species. In addition to this, the form of A = b_0 + b₁LW and A = b_0 + b₁L² + b₁W² were founded to be suitable for estimation of leaf area. In comparision of these two forms, the determination coefficient were about the same, but the F-value of the former was greater than that of the latter. Therefore, the use of the former seems to be more reliable and practical.
