Several universities in Korea are beginning studies related to soft stamping processes but since the studies are done with manual works thus systematic tests can't be performed due to difficulties in producing reproducible and repeatable fine patterns. Therefore, the phenomenon of destruction of the pattern forms of elastic polymers occurred during working because of inconsistent printing pressures and pinting time and there have been difficulties in maintaining flatness or producing uniform and fault-free fine structures in pinting large areas and also, there have been difficulties in multi-layered processes as patterns were changed by contacts in registering and errors in alignments. The purpose of development of this technology is to improve the process of soft lithography so that contacts between PDMS stamps and metal coated substrates in order to develop a stamp printing device that can not only shorten but also optimize processes, secure reproducibility and repeatability and is advantageous in printing large areas. Also, using this technology, this author is to develop equipment technologies and applied technologies for nano grade pattern printing processes with new concepts based on fine contact printing processes in order to apply them to diverse nano pattering processes.

Zoning areas within national parks in Korea are classified into Natural Preservation Zone(NPZ). Natural Environment Zone(NEZ), Settlement Zone(SZ) and Mass Facility Zone(MFZ) based on the Natural Park Act Large-scale development which might cause permanent destruction of natural resources are being done in NEZ which covers 90% of the total natural park area. Thus it is necessary to examine National Park Act which refers the authorized criteria and development activities of NEZ. However, the current environmental impact statement(EIS) does not cover the full impact of the development inside the national park area. Based on these concepts, the study examines the appropriate resources to distinguish the NPZ and NEZ in Mt. Teogyu National Park, then compare the distribution of resource characteristics between two area by using GIS. Through this study, the conclusions are as follows; (1) In terms of scenic resource analysis, the current NPZ does not meet the criteria on the National Park Act Rather, most of the resources which should be located within the NPZ are located within the NEZ. (2) In terms of elevation analysis, Mt. Teogyu National Park, most of NPZ are located on high altitude which is more than l,200m above the mean sea level. Therefore, it shows the elevation is the only criteria for distinguishing NPZ and NEZ. (3) In terms of Degree of Green Naturality(DGN), the second forest areas, the eighth grade of DGN in Mt. Teogyu National Park are distributed much more in the NEZ than NPZ. (4) After examining five factors - scenic resources, elevation, slope and DGN, vegetation- it was found out that zoning of Mt. Teogyu National Park is not adequatly designated. Zoning of national parks should be accomplished based on the precise inventory of the current resources.

Objectives : Many surgical procedures have been introduced to a symptomatic lumbar stenosis. Most of these procedures still have been regarded as an extensive surgical intervention with respect to normal aging process of the lumbar spine. We adopted a microsurgical decompression procedure via unilateral exposure as a minimally invasive intervention for symptomatic lumbar stenosis without instability. Materials and Methods : Fifty-seven patients with symptomatic lumbar stenosis underwent microsurgical decompression via unilateral laminotomy between March 1998 and December 1999. The conceptual modification and technical refinements were added to the previously reported microsurgical decompression procedure. Bilateral decompression through a unilateral laminotomy hole was performed in 11 patients. These patients profile also included 9 cases of degenerative spondylolisthesis(Grade I) without instability. Results : Preoperative neurogenic intermittent claudication(NIC) was more notably improved than low back pain, 60% to 82% during the follow-up period. Overall clinical results were excellent in 20(35%), good in 29(51%), fair in 6(11%) and poor in 2(3%). Conclusions : Microsurgical decompression for lumbar stenosis with stable spine provided a satisfactory symptomatic improvement without extensive destruction of the weight-bearing structures and functional mobile segments, even bilateral symptoms existed.

Today, we live in the fastly changing society, rapidly developing scientific civilization and repeatly confusing political culture. Therefore, man persuits the emotional rest in "eros" and sympathizes with eroticism. Such an eroticism represents too much in art and costume all over the world. the purpose of this study is to classify the ex-pressive style of eroticism which is the feature of the costume in the first year of 1990's and to analyze its expression meaning. This study will be a basic data of new design development and help predict the costume in the latter half of the yeat. The method of this study was performed by using the literature related to the eroticism and the study of preceeding researchers. To analyze the costume style the its implied meaning being used to express the eroticism of 1990's, the magazines(Elle, Vogue, WWD, Collections etc) and the literatures related to fashion were used. The styles and meaning of eroticism expressed eroticism by using the minimal design which exposes wholly or partly by using a transparent vinyl and a see-through clothing. The sexy style arose from the expression of social rebellion and the exposure of suppressive sex as a psychological repulsion against the older generation. 2) Deshabille style : This style is the conver-sion to the outer garment of an underwear. The excessive exposure which just concerns the inti-mate parts of the body by using the thin cloth or lace for an underwear. This style can be recognized as the beauty destruction and ugly 3) Glamour style : The style is made up of the high-grade cloth such as silk and velvet and expresses the bodily beauty. This style falls into a rebellious culture and comes from the inten-tional expression to escape the modern life which is straight and hard. 4) metallic style : This style uses variously the new material such as vinyl-coating, enamel and represents the eroticism through the original expressions.pressions.

This paper presents structural characteristics of station class lightning arresters and electrical characteristics of manufactured ZnO varistor blocks which are usable in those arresters. Three types of station class lightning arresters were investigated and those are a ceramic arrester, a FRP tube type polymer arrester, and a FRP rod type polymer arrester. Each arrester has merits and demerits with structural characteristics. In general, polymer arresters were made of silicon rubber for housing materials, FRP tube or rod for mechanical strength, ZnO blocks for electrical characteristics, and metal parts for electrical contact and the silicon rubber, the housing materials, was directly injected to the arrester module which was assembly composed of electrodes, ZnO blocks and FRP tube or rod, and to prevent the nonlinear electric fields distribution on upper parts of arresters, the grade ring was adopted to the upper electrodes. The reference voltage, nonlinear coefficient, residual voltage, and voltage ratio of manufactured ZnO varistors are 4.90kV, 50, 9.54kV, 1.94, respectively. Compared to designed electrical characteristics, the reference voltage was low for 600v and the voltage ratio was slightly high. However, the characteristics of discharge withstand was so excellent that the mechanical destruction does not occur at the impulse current of $8/20{\mu}s$ 10kA for 100 times.
