Korea is a nation with poor natural resources. There is a greats need to save resources that are running out in fast face. The purpose of this thesis is to bind the means to save rosources in housing site, especially in highrise apartment. The reason why the high-rise apartments are chosen as a case is 7hat the high-rise is becoming the major form of dwelling in most urban areas. As a tool of saving the ecological way is chosen because ecological energy is free, clean and unlimited. The resources to be saved are divided into two categories, namely energy and non - energy resources as water, land and food. The contents of the thesis are comprised of 4 chapters. The early chaspters are devoted to the understanding of the ecosystem and problems of current energy consumption in the apartment. It is fellowed by the introduction of the hypothesis that can possibly save reouruces. The hypothesis are then transformed into the actual theories through verification, to be established as the new techniques of the site planning. The ecosystem is the functional relationship between the living organisms and their physical surroundings. The living organisms are the plants that produce, animals that consume and bacterias that decompose. They live in the environment which consists of the three worlds of atmosphere, hydrosphere and lithosphere. The whole system is activated by the solar energy that turns the inorganic mallet- into the living organism and back to the inorganic. It is the recycling principle of the ecosystem. The elements of ecosystem that fan be unilimited as the tools of resources -saving are the sun, wind, water, soil, plant and waste. They are unlimited sources of energy. free of pollution and cheap in price. Each of these ecological elements Provide the opportunities that can save the heating fuel, air conditioning energy, water resource, land and food. The ecological approch should be pursued actively in this age of short resources and growing pollution. In the scale of total energy consumption the housing takes the second position next to the industrial use. It is followed by the transportation which shows for less consumption than former two.

This paper has tried to analyze the characteristics of space in Korean traditional architecture by deconstructive concept through connecting Lao-tzu's theory, the main discourse of East and West, with Derrida's deconstructionism theory. Derrida's philosophical term of differance(diff$\acute{e}$rance) is similar to Tao of Lao-tzu. It is because Derrida emphasized the relationships with others by trying the strategy of overcoming dichotomous thinking by this term. Tao of Lao-tzu also has the relative characteristics that cannot be concluded by one sole meaning. Like this, Derrida and Lao-tzu are against traditional and dichotomous way of thinking. In this point of view, this study has set Derrida's deconstruction theory and Lao-tzu's thinking as the common viewpoint of this world. And through the phrase of Tao Te Ching which means deconstructive Tao, deconstructive space design vocabulary was derived as mixed no-boundary, shape of no-shape, transcendence of time and space. The deconstructive characteristics of traditional space by case study analysis of Lao-tzu's deconstructive space design are as follows: First, it is not a specific or detailed shape but an unlimited possibility that can be transformed into something else, moving and changing endlessly and has a borderless beauty. Second, it is nothing itself but creates various shapes, as if it exists without shape. Third, it is a relative and unlimited space and pursuits a free form as a non-conceptional shape without any system or value.

This study deals with the evolutional history of the holding and utilization of fisheries resources in Korea. Fisheries resources have the basic characteristics of the density dependent self-regulating renewable and common property resources, Irrational utilization of fisheries resources is mainly due to the unlimited access to the resources. The holding and utilization of fisheries resources in Koryo era was opened to everyone. But it was nationalized in the early Yi Dynasty. The purpose of its nationalization was to provent the paticular powered-man with their monoplized holding and to levy fisheries tax. Eoeop-peop, the first modern fisheries law in Korea, was enacted as a part of the invasion policy of Japan in 1908. With the japanese annexation of Korea in 1910, the Japanese Government established a new institutional system of fisheries as a part of an overall reformation of the institutional for an implementation of the colonial policy. It was very the new enacted Fisheries Law (Gyogyorei). Also the Government enacted compulsorily another new Fisheries Law (Chosen Gyogyorei) with its adjunct laws and regulations revise the institutional system of fisheries on May 1, 1930. After Eoeop-peop enactment, the fisheries resources in Korea could be used only under the license, permission, and statement. After Korea was from Japan in 1945, Korea Government at last enacted the new fisheries law (Susaneop-peop) in 1953. The goal of Susaneop-peop was to achive the general usage and protection of the fisheries resources, and to attain the development and democratization of the fishery in Korea. This law was amended 13 times until 1990. The license fishery have a legal right on the fishery, called a fishery rigt. This right means a right of exclusive occupation and utilization of a unit of the inshore fishing grounds. The main evolutional issues of license fishery are as the following : 1) the foundation of the exclusive usable fishery right(1911, Gyogyorei), 2) the deletion of the settled U9space lift net and settled space sein net fishery, and the expansion of the cooperative fishery-No.1, 2, and 3 type cooperative fishery-(3rd amendment, 1963), 3) the deletion of the No.2 and 3 type cooperative fishery, and the separation of the culturing fishery in No.1 and 2 type culturing fishery (13th amendment, 1990). The effective period of the license fishery was amended as the following : 1) 1908(Eoeop-peop) : within 10 years, renovation system, 2) 1929(Chosen Gyogyorei) : within 10 years, unlimited extension system, 3) 1971. 7th amendment : 10 years, renovation system, 4) 1972. 8th amendment : 10 years, only 1 extension system, 5) 1975. 9th amendment : 5-10 years, only 1 extension system, 6) 1990.13th amendment : 10 years, within 10 years of total extensional years. The priority order of the fishery license was established in 1953 (Susaneop-peop). The amendment of it is as follows : 1) 1953. enactment \circled1 the fishing grounds that the fishery right is extablished 1st order : the existing fishery right man, unlimited renovation 2nd order : the corporate that the regional fisherfolk organized 3rd order : the rest experienced fishermen \circled2 new fishing grounds 1st order : the corporate that the regional fisherfolk organized 2nd order : the rest experienced fishermen 2) 1971. 9th amendment \circled1 the fishing grounds that the fishery right is established 1st order : the existing fishery right man, unlimited renovation 2nd order : the Eochongye that the regional fisherfolk organized 3rd order : the regional fishery cooperative that the regional fisherfolk organized 4th order : the rest experienced fishermen \circled2 new fishing grounds 1st order : the Eochongye that the regional fisherfolk organized 2nd order : the regional fishery cooperative that the regional fisherfolk organized 3rd order : the rest experienced fishermen 3) 1981. 10th amendment \circled1 the inside of No.1 type cooperative fishing grounds 1st order : the Eochongye that the regional fisherfolk organized 2nd order : the regional fishery cooperative that the regional fisherfolk organized 3rd orer : the rest experienced fishermen 4) 1990. 13th amendment \circled1 No.1 type cultural fishery 1st order : the Eochongye that the regional fisherfolk organized 2nd order : the regional fishery cooperative that the regional fisherfolk organized 3rd order : the rest experienced fishermen \circled2 No.2 type cultural and settle fisher : general priority order The effective period of the permission fishery was amended 6 timed. First, it was within 5 years and renovation system (Eoeop-peop). Now it is 5 years and renovation system. The effective period of the statement fishery was amended 4 times. First, it was within 5 years, and then was amended within 3 years(Chonsen Gyogyorei). Now it is 5 years.

Monoclonal antibodies (Mabs) have been used as diagnostic and analytical reagents since hybridoma technology was invented in 1975. In recent years, antibodies have become increasingly accepted as therapeutics for human diseases, particularly for cancer, viral infection and autoimmune disorders. An indication of the emerging significance of antibody-based therapeutics is that over a third of the proteins currently undergoing clinical trials in the United States are antibodies. Until the late 1980's, antibody technology relied primarily on animal immunization and the expression of engineered antibodies. However, the development of methods for the expression of antibody fragments in bacteria and powerful techniques for screening combinatorial libraries, together with the accumulating structure-function data base of antibodies, have opened unlimited opportunities for the engineering of antibodies with tailor-made properties for specific applications. Antibodies of low immunogenicity, suitable for human therapy and in vivo diagnosis, can now be developed with relative ease. Here, antibody structure-function and antibody engineering technologies are described.

Design has been proceeding to 21 century undertaking the many-sided and complicated characteristics of the modern industrialized society much more heavily comparing to past. The rapid change of technology and media of communication faces the new concept of relationship between users and environment, and newly developed material leads designers to change the way of building concept and the process of designing. Especially the important points of user-friendly and environment-friendly approaching for designing influences over choosing, controlling meterials and forming the structure and shape organically, or simply. From the tendency of chairs designed in 1990s the very adaptable new material shows both the unlimited possibility for new design is in the turn of this century, but also it can be analogized that 'the design which can make users think' will be the philosophical basis for future desigv.

This paper is to study the energy absorption characteristics of CF/Epoxy(Carbon Fiber/Epoxy Resin) laminated shell with the various curvatures subjected to transverse impact loadings under the low impact velocity in consideration of design of structural members for use of transportation machine, which are consisted of the characteristics of high stiffness, strength and lightweight. The curvature radius are associated with the energy absorption characteristics of CF/Epoxy laminated shell which is brittleness material. In all tests, maximum load of CF/Epoxy laminated plate is higher than that of laminated shell with curvature, but maximum deflection is lower. And then absorbed energy of laminated shell with curvature is higher than laminated plate(curvature radius is unlimited), As curvature radius is increased, the absorbed energy is increased in laminated shell with curvature.
