This study suggests institutional and methodological approaches for preservation of South Korea's registered cultural properties of modern architecture. The suggested approaches are as follows. First, in order to improve the current registration and preservation system for cultural properties, we need to employ both structure-based classification and style-based classification. Registration criteria for modern architecture properties need to include more detailed classification in terms of their structure: brick structure, steel concrete structure and post lintel structure. In terms of construction style, the properties need to be further classified into the western style, the traditional style and the Korean-western eclectic style. In addition, protection of registered cultural properties need to be achieved through legislation of a protection system. Second, while the current system sets out six methods for preservation of registered cultural properties of modern architecture, more specific preservation methods types and plans need to be continuously introduced. In particular, as for the method of partial preservation, the method needs to be further classified based on the usage of the relevant structure so as to allow for more diverse options. First, the 'Preservation by Interior Alteration' needs to be added to the category, where the exterior is preserved as it is and the interior is preserved through alteration. Also needs to be added the preservation method where the interior space is preserved as it is and the exterior space is altered, in case the finishing materials of the exterior has deteriorated. Third, if the records on registered cultural properties of modern architecture are to provide the functions of legal evidences regarding management of architectural cultural properties, sources of knowledge required for policy making and implementation and past management record for the future, each phase needs to be closely connected in an organic manner, and we need to establish a management system and plan that go beyond the relevant organizations. Fourth, in order to preserve South Korea's registered cultural properties of modern architecture in its original state, it is imperative to prepare separate criteria for registration of technicians with expertise on modern architecture, and train experts and technicians on modern architecture, which is distinguished from the traditional architecture.

Amended Water Quality Environment Preservation Law enacted that the areas where nonpoint pollution is serious can be designated as Nonpoint Source Management Region. According to Section 54 of Water Quality Environment Preservation Law, corresponding watersheds are areas where runoff from nonpoint pollution source may deteriorate river and lake water quality, residents' health and property, and ecosystem. The criteria are as followings; i) where nonpoint source contribution result in or will result in significant ecological destruction, iii) national or local industrial complexes and cities having population greater than one million where nonpoint source managements are necessary, iv) where specific measurement is necessary because of its geological and stratigraphic characteristics. In this research, detailed designation criteria was developed reflecting current nonpoint source management situation and its discharge characteristics. Depending on the result, target regions were also suggested. In additions, it will be desirable that the target regions are prioritized considering institutional execution availability, stakeholder's agreement, and connection with existing nonpoint source pollution management measures.

Traditional housing must be conserved simultaneously with not only the building itself, but the circumstances of the surroundings. Hence, traditional housing should be developed as a product of a culture environment. However, most cultural properties have recently been treated as only a piece of property by irresponsible maintenance practices and damage placed on private traditional housing. Apparently, it has not always been a result of dweller's negligence. Thus, various policies must be needed to effectively preserve traditional housing. To do so, this study will indicate a new direction for the circumstance of preservation through cultural employment of traditional high-class housing as well as reduce maintenance and damage for dweller's convenience. Furthermore, this study will propose a renovation for popularization of Korean cultural assets through the gradual implementation of both economic value and public worth.

Traditional wall is ground coat, twice plater, last plaster by such a process has made a wide variety of used materials and techniques are accordingly diverse. These traditional techniques handed down the traditional walls of the techniques, rather than coming to the lowered cut off at any moment from now when the technique is used, not knowing whether to be used. Repair and restore cultural property maintenance work, it is not only the outward form hiding inside it is a technique to keep the preservation of cultural assets can be called true. When viewed from the side walls of these conventional techniques to reveal changes in the traditional process by looking at the changes in technology with traditional techniques for cause shall be made in stock. This paper is from the late Joseon Japanese occupation of techniques ranging from traditional wall to reveal the change process to its current significance of cultural property repair method to be helped.

Museums have conducted the role of conserving, collecting, and displaying cultural property generally but main museum function transforms the role of social educational place accomplishing various instruction programs .recently through social perception's changing. Educational function of museum having experience program is more effect than before that. Museums need exhibition for preservation of property in regional community and history, as well as certainly require the concept to importing experience program. Through analysing experience program patterns and varieties in domestic museum. I will propose basic dater to supply preliminary and intermediate study.

Five type boxes manufactured from cement(A), wood panel(B), charcoal-packed wood panel(C), plywood panel(D) and charcoal-packed plywood panel(E) were prepared. Relationship of preservation characteristic of strawberry and relative humidity, and properties of thermal and sound insulations in the boxes were examined. During the experimental duration, relative humidity in the cement box was highest and lowest in the charcoal-packed wood panel box. Weight loss of strawberry was greatest in charcoal-packed wood panel box and very little in cement box. In the boxes with charcoal-packed wood panel box and very little in cement box. In the boxes with charcoal, strawberry was preserved for 10 days without getting mold, but in cement box it was covered with mold in 3 days. The charcoal-packed boxes showed higher thermal insulation property than the cement box. There were no significant differences in the property of sound insulation among the 5 type boxes. Consequently, it is suggested that charcoal-packed wood panels can be used for a better ecomaterial.

The result of the study on the origin and preservation status of the 'Gongju Junghakdong old missionary house', the Registered Cultural Property No. 233, reveals that the building was approved on October 23, 1921, and missionary Alice H. Sharp was living in the building until her retirement from her missionary life of 39 years in Korea in 1939. In order to review internal and external preservation status of the building, condition of wood material, the composition of the window, the damage of the wall, and the leaning of the building were examined. In particular, in the case of window facilities, it is necessary to restore it to the original upper and lower sliding window. As a result of investigation of the preservation status of the external facilities, it is necessary to restore the original shape of the staircase and a deck of the building on south western side and the well. In addition, the results of the non-destructive diagnosis of the ground revealed that the building was built on uneven surface layer of 2-5 m thickness and the boundary between the surface layer and the upper part of the weathered rock is inclined following geomorphology. This phenomenon shows that when the water content of the ground increases in the rainy season, the bearing capacity of the ground is lowered, and there is a possibility of uneven subsidence. Especially, landslides may occur in case of heavy rain. Therefore, it is desirable to install a masonry facility at the southwest boundary of the site, and it is recommended to install a drainage facility to ensure rapid drainage.

Let N be a normal subgroup of a path-connected topological group (G, $t$). In this paper, the authors consider the existence of path-connectedness in refined topologies in order to address the property of maximal path-connectedness in topological groups. In particular, refinements on $t$ and refinements on the quotient topology on G/N are studied. The preservation of path-connectedness in extending topologies and translation topologies is also considered.

A stable preservation method of extracellular non-occluded virion of Autographa californica nuclear polyhedrosis virus (AcNPV) was studied. AcNPVL-1 strain infected to Spodoptera frugiperda cell line and then the culture media were centrifuged. After centrifugation the supernatant containing extracellular nonoccluded virions of the AcNPV was harvested and incubated at $4^{\circ}C$ . Even after the extracellular nonoccluded virions were incubated at $4^{\circ}C$ for about 11 years, the infectivity and multiplication property of the nonoccluded virions in the S. frugiperda cell line were normal. However the titers of the nonoccluded virions in TC-100 medium measured about 11 years ago decreased from $8.9 \times 10^7\; to \;3.8 \times 10^5$ pfu per ml. The AcNPV genome DNA fragment patterns from digestion with Hind11 and EcoRI restriction endonucleases did not change. The AcNPV nonoccluded virions were stable at $4^{\circ}C$ in the cultured medium of more than 10 years and the preservation of AcNPV nonoccluded virions at $4^{\circ}C$ is easy and useful for handling.
