In this study, we investigated the applicable plan of GIS on the environmental impact assessment of 60 Hz Powerline. So we assessed distance data based on calculations by use of 2D and 3D Geographical information systems(GIS) and distance data based on measurements on 1: 5000 maps accord with on site distance measurements to use input data for calculating magnetic field. One hundred eight of the on site measured addresses were selected from residences. The data were achieved by measuring the distance between residence and power line on maps with scales of 1: 5000. The digital map was obtained from National Geographic Information Institute with scales of 1: 5000, and we made 2D and 3D map. Correlation analyses were performed for statistical analyses. For the 3D GIS versus on site comparison of different exposure categories, 70 of 108 measurements were assigned to the correct category. Similarly for 2D GIS versus on site comparison, 71 of 108 were correctly categorized. When comparing map measurement with on site measurement, 62 of 108 were correctly categorized. When the correlation analysis was performed, best correlation was found between 3D GIS and on site measurements with r = 0.84947 (p<0.0001). The correlation between map and on site measurement yielded an r of 0.76517 (p<0.0001). Since the GIS measurements and map measurement were made from the center point in the building and the on site measurements had to be made from the closest wall on the building, this might introduce and additional error in urban areas. The difference between 2D and 3D calculations were resulted from the height of buildings.

This study was conducted to investigate the influence of eco-friendly restoration in forested bog on the structure of benthic macroinvertebrate community. The benthic macroinvertebrates collected from the surveyed sites were composed of 1,071 individuals, 60 species, 40 families, 13 orders, 6 classes and 5 phyla. At the control and Site 3(small dam), the number of species and individuals were larger than that of other sites, and EPT group ratio was same as well. Considered by index, the dominance index (DI) was found the highest at the biotope area. The diversity index (H') and richness index (RI) were the highest at the control and Site 3. In addition, the ecological score of benthic macroinvertebrate (ESB) showed the highest at site 3, while the lowest at biotope area. The stability and recovery of benthic macrointebrates showed different according to restoration types at forested bog. After restoration project, the benthic macroinvertebrates were observed to get recovery at Site 3, and to have the highest communities stability at control and Site 3. At biotope areas (Site 4, Site 5 and Site 6) communities stability were the lowest, but showed different community stability values according to the presence of water. It is confirmed that the eco-friendly restoration projects indeed provided the better environment for the inhabitation of benthic macroinvertebrate community. The change of community index depending on the restoration projects suggests that the eco-friendly restoration can provide a more suitable environment for benthic macroinvertebrate ecosystem that prefers the stream environment.

Taekwondo, Korean traditional martial art as one of the ten Korean cultural symbols, has acquired a reputation for introducing and globalizing Korean culture together with its standing as official Olympic Game in 2000, Sydney, Australia. Nevertheless the World Taekwondo Headquarters, Kukkiwon, which is an exclusive Taekwondo institution only accommodates for three thousand persons. Considering the worldwide reputation of Taekwondo, the scale of Kukkiwon leaves a big supply problem. This study therefore suggests the plan to design Taekwondo park that playa major role of Taekwondo development in the 21st century and represent the cultural heartland of Taekwondo. The study considers four points. The points are as follows: 1) Necessary programs drawn by analyzing and assessing Muju city as a site for Taekwondo park, then a survey conducted for potential visitors to a Taekwondo park. Under the theme of "A World Cultural Heritage Upon Our Own Lives", the park plan intends to become a shrine of Taekwondo as well as a big tourist attraction. 2) Programs are appropriate for the terms of the investment under the auspices of government, by considering potential visits and the site conditions. 3) The meaning of Taekwondo and its history should be reflected in the space distribution and facilities allotment. Three meaningful zones: symbolic zone, training zone and culture zone are considered in planning program and space distribution. 4) The plan also intends to harmonize with local development by groping Muju city's uplifting, not only designs a Taekwondo park.

This design proposal was presented to a design competition for renovation of the Pagoda Park, located in Chongro-2ga, Chongro-gu, Seoul, where the first ˝Manse˝ (hurrah) Movement fighting against Japanese colonization, broke out on March 1st, 1919. The park has been considered to be the first modern park in Korea also. The objectives for the design were to make a sacred place to commemorate the 3.1 ˝Manse˝ Movement, to preserve and symbolically memorialize historic remains of the old ˝Wongaksa˝ Temple, an to provide natural and rest areas for citizen. For the space composition, three axes symbolic of, ´freedom and independence´, ´mercy´, and ´nature´, were created. For the freedom and independence axis, exiting facilities, such as statures and monuments related to the 3.1 Movement, were relocated centering around the octagonal pavilion, which was the starting point for the movement, to give order of the site. For the ercy axis, symbols of traditional temple structures, such as, ´Iljugate´-´Pian bridge´-´Chongwang gate´-´Haetal gate´-Pagoda-Buddhist sanctum, were created to symbolize the temple remains and placeness. For the nature axis, tree groves, walking trails, and rest areas for citizen were provided around the site. As a whole the design provided structural orders from secular spaces outside to sacred spaces inside.

This study was performed to propose the site selection plan for the restoration of the target Reeve's turtle (Maunemys reevesii) habitat and has developed the AHP model to select the optimal site for Reeve's turtle habitat restoration on the basis of the Reeve's turtle Habitat Suitability Index (HSI) items (factors and variables). The assessment areas were established by the Reeve's turtle HSI factors such as breeding space, feed, cover, water, threatening factors and others and the sub-assessment items by each assessment area were established based on the Reeve's turtle HSI variables. The weighting values of the assessment areas and items were calculated by the developed AHP method. The weighting values of the 5 assessment areas were arranged in order as breeding space(0.293), food(0.273), water(0.217), cover(0.113), and threatening factor(0.104). The final weighting values of the 17 assessment items were arranged in order of height as all kind of food(0.222), water depth(0.096), altitude of spawning ground(0.093). The scoring criteria according to the assessment items and factors were marked and applied by equal intervals considering the criteria by HSI items of the Reeve's turtle and finally the scoring criteria diagram as been proposed for the optimal site selection of the Reeve's turtle habitat restoration.

As the complexity of society increases, the demand for the forest-based recreational site is also increased. This, in turn. makes congestion an ubiquitous type of externality in forest-based recreational site. Efficient resource allocation requires this congestion effect to be accounted and considered in the decision making process. In this content, this study was conducted to suggest a process which can be used to measure the congestion and determine the optimal number of users. Willigness to pay(WTP) function obtained from Book Han San National Park users suggested that every 20.000 users increased decrease the satisfaction of users obtained from the site visit be 27.3%. For the purpose of demonstration this WTP function is applied tit determine the optimal number of users which is estimated as about 73,000 persons per day.

Site coefficient and amplification factor of current domestic Seismic Design Code based on American Seismic Code, have no consideration for the domestic ground condition in which the base rock is normally placed within 30m form the surface. By previous studies, the measured spectral acceleration of the result of dynamic centrifugal test and analysis was smaller than the design spectral acceleration for the period over 1.5 sec. Accordingly, in this study structural analysis and design using dynamic centrifugal test result for pile foundation were achieved, and the quantity of concrete and reinforcement of wall frame was compared with each other. Comparison results of cost using KBC the design spectral acceleration of SC, SD site and SDS, the quantity of reinforcement using SDS for SD site was 17~23% smaller than using the design code SD site.

From each sediments collected at Chudong(static) and Hoenam(streaming) site of Lake Daechung on May 18(before rainy season) and on August 24 in 1998(after rainy season), different strains of Actinomycetes were isolated and identified to genus level. For comparison, the genus diversity of Actinomycetes in control soils such as grass land around lake, lake shore, and shallow(5-10cm) lake was also investigated. In consequence, the isolation of Streptomyces from the sediments of Lake Daechung was the most copious(41 strains) at the streaming site before rainy season and the least(27 strains) at the static site before rainy season, which were 2.4- and 1.6-fold larger than the average(17 strains) of control soils, respectively. In addition, the isolation of rare Actinomycetes from the sediments of Lake Daechung was the most copious(23 strains) at the streaming site before rainy season and the least(12 strains) at the static site after rainy season, which were 3.2-and 1.6-fold larger than the average(17 strain) of controls, respectively. Therefore, it is considered that lake sediments exhibit higher diversity of Streptomycete as well as rare Actinomycetes than general soils, and thereby can be utilized as useful sources to isolate diverse Actinomycetes.

The purpose of the study was to develop a Web site for the middle-aged women and test the usability of the site. Users' need for information were identified via online survey of 189 middle-aged women. It was found that they had various health problems but very few did any health prevention or health promotion activities. A web site for the middle-aged women was developed based on the result of needs assessment. The site includes content on exercise, diet including weight control, osteoporosis, climacteric, aging, breast and cervical cancer. Besides this health information, FAQ on women's health, my health knowledge test, statistics, link to related institutes and web sites, newspaper articles/mass media clips, journal articles, conferences, papers and other educational information were added. The site was developed as a subsystem of the Healthguide(http://healthguide.kihasa.re.kr). As a way of utilizing the homepage, twenty two women aged 40-50 were recruited at a community-based gathering and health promotion education program was conducted. To test the effectiveness of the education, knowledge, attitude and behavior changes of before and after education were compared. There were significant differences of knowledge and behavior in breast cancer, cervical cancer, osteoporosis, menopause and sexual life. It is expected that Web-based women's health information will contribute to women's health promotion and provide an effective learning media for health education.
