The responsibility of keeping and caring of unearthed cultural properties belongs to the National Museum according to cultural properties protection law(law No.3644). So unearthed cultural properties are possessed by the museum after going through the regular course. Number of those cultural properties is increasing swiftly. Every year more than ten thousand units of cultural properties are unearthed. The number of unearthed cultural properties is expected to increase in the future. Howeve, the keeping facilities of the National Museum are already over-saturated. So many unearthed cultural properties are being entrusted to university museums that have bad facilities and few personnel. It makes many problems including inadequate caring. More pressing problem is that those cultural properties are not under the protection of scientific conservation processing and caring. The reason is that there are so few conservation scientists in Korea. There is no independent department of conservation science even in the National Museum, where only five members are working as conservation experts. To solve those problems, new system and organization which win take charge of conservation and care of cultural properties, that is, an organization which will consist of scientific keeping facilities and expert personnel (conservation scientists) is needed immediately.

The North Korean laws on natural environments, land and infrastructure were comprehensively analyzed in order to help establish the legal system to solve problems of ecosystem and land management in North Korea. The citizen's environmental rights in North Korean Constitutional Law emphasize the aspect of conservation of the natural environments. The laws on the managements of natural environments and land are relatively integrated in North Korea. In the management of natural environments, ecosystem conservation is centered on designation of natural protected areas. Priority for infrastructure construction is emphasized in land management. The economic and technical support is needed to build advanced legal systems for the conservation of natural environments and ecological land management and to improve their performance of law enforcement.

To investigate the moderator coolability for CANDU-6 reactors, a test facility (HU-KINS) has been manufactured as a 1/8 scaled-down of a calandria tank. In the design of the test facility, a scaling law was developed in such a way to consider the thermal-hydraulic characteristics of a CANDU-6 moderator. The proposed scaling law takes into consideration of the energy conservation, the dynamic similitude such as dimensionless numbers, Archimedes number (Ar) and Reynolds number (Re), and thermal-hydraulic properties similitude. Using this proposed scaling law, the thermal-hydraulic scaling analyses of similar test facilities such as the SPEL (1/10 scale) and the STERN (1/4 scale), have been identified. As a result, in the case of the SPEL, while the energy conservation is well defined, the similarities of Ar and the heat density are not well considered. As for the similarity of the STERN, while both the energy conservation and the characteristics of Ar are well defined, the heat density is not. In the meanwhile, the HU-KINS test facility with 1/8 length scaled-down is well similitude in compliance with all similarities of the energy conservation, the fluid dynamics and thermal-hydraulic properties. To verify the adequacy of the similarities in terms of thermal-hydraulics, a computational fluid dynamic (CFD) analysis has been conducted using the CFX-5 code. As the results of the CFD analyses, the predicted flow patterns and variation of axial properties inside the calandria tank are well consistant with those of previous studies performed with FLUENT and this implies that the present scaling method is acceptable.

The purpose of this paper is to propose directions for urban greening and nature conservation in small-to-medium-sized cities in Korea for implementation of the Local Agenda 21 (LA 21 hereafter). In this paper, the status of implementation of the LA 21 in both Korea and Japan have been examined. In addition, the green-related plans of both countries have been compared. The cities of Jeonju and Sagamihara were chosen as examples to compare. The result of the research is as follows: 1)With regard to the responsible bodies, in Korea, the implementing plans were initiated by the environment-related authorities of local governments while, in Japan, the plans of action were initiated through consultative committees reflecting opinions from citizens and business entities. 2)Concerning the status of implementation of LA 21, the city of Jeonju has adopted a plan of action and then implemented the plan through a consultative body without adequate legal ground. On the other hand, the city of Sagamihara has enacted a local ordinance to implement the LA 21 It was learned that the newly enacted ordinance has positively been interrelated to existing environmental plans. 3)Regarding urban greening and nature conservation plans, the city of Jeonju has focused on comprehensive measures to preserve and restore ecology while the city of Sagamihara has clearly suggested educational purposes in its plans in addition to preserving and restoring ecology. 4)In terms of support by law or legal system concerned, it has been teamed that, compared with Japan, Korean plans have not been properly supported by law or the legal system to urban greening and nature conservation plans. The same was shown in the city of Jeonju as compared with the city of Sagamihara. As for future directions, the follow are proposed: 1) establishment of a local Committee on Sustainable Development, 2) enactment of relevant and regulations such as the Master Plan of Parks and Green Open paces, 3) establishment of ecological greening plans.

Deforming mesh should be used when bodies are deforming or moving relative to each other due to the presence of aerodynamic forces and moments. Also, the flow solver for such a flow problem should satisfy the geometric conservation law to ensure the accuracy of the solutions. In this paper, a RANS(Reynolds Averaged Navier-Stokes) solver including automatic mesh capability using TFI(Transfinite Interpolation) method and GCL is developed and applied to flows induced by oscillating wings with given frequencies. The computations are performed both on deforming meshes and on rigid meshes. The computational results are compared with experimental data, which shows a good agreement.

In general, the information of inertia properties is required to control a spacecraft. The inertia properties are changed by some activities such as consumption of propellant, deployment of solar panel, sloshing, etc. Extensive estimation methods have been investigated to obtain the precise inertia properties. The gyro-based attitude data including noise and bias needs to be compensated for improvement of attitude control accuracy. A modified estimation method based on the law of conservation of angular momentum is suggested to avoid inconvenience like filtering process for noise-effect compensation. The conventional method is modified and beforehand estimated moment of inertia is applied to improve estimation efficiency of product of inertia. The performance of the suggested method has been verified for the case of STSAT-3, Korea Science Technology Satellite.

Domestic laws such as Korea Marine Pollution Prevention Law which has been made and amended according to the conclusions and amendments of various international conventions, especially by MARPOL 73/78, were reviewed and compared with major contents of international conventions, and several alternative measures for legislating new laws or amending existing laws such as Korea Marine Pollution Prevention Law in accordance with new contents and recent amendments of existing and new international conventions were proposed. Annex VI of MARPOL 73/78 has been recently accepted in Korea Marine Pollution Prevention Law which should be applied to ships which are the moving point sources of air pollution at Sea rather than in Korea Air Environment Conservation Law which should be applied to automobiles and industrial installations which are the line and/or point sources of air pollution in land. International Convention for Ship's Ballast Water/Sediment Management should be accepted in Korea Marine Pollution Prevention Law or by a new law in order to prevent domes marine ecosystem and costal environment from the invasion of harmful exotic species through the discharge of ship's ballast water. International Convention for the Control of Harmful Anti-Fouling Systems on the Ships should be accepted in Korea Marine Pollution Prevention Law which should be applied to ships which are navigating in open sea and coastal waters rather than in Korea Noxious Chemicals Management Law. Basel Convention which shall regulate and prohibit inter-nations movements of noxious chemical substances should be accepted in Korea Marine Pollution Prevention Law in order to prevent the movement and transfer of scrap-purpose tanker ships containing bilge water of oil/water mixtures and chemicals remained on board from advanced countries to developing and/or underdeveloped countries and to conserve global marine environment after all.
