The concentration of heavy metal were studied for the estimation of quality in herbal medicines which is Bupleuri Radix, Paeoniae Radix, Dioscoreae Rhizoma and Astragali Radix in products of north Kyungbuk area. And we compared with heavy metal concentration of herbal medicines in products of Kyungbuk and the other area of Korea. Also, we collected soils from several area in Kyungbuk, and determined heavy metal concentration of soils by ICP. We compared with herbal medicines in products of Kyungbuk and their soils. The results were as follow : Kyungbuk area appear to be more proper to cultivated land than other area. For the heavy metals contents of Kyungbuk area, in Gong Jung Ri, represented the higher level, it may be due to a near the road. Correlation coefficients of heavy metal contents in cultured herbal medicines and their soils did not give reproducible results.

As a rational decision-making process of county-level area development, this study designed 3-step framework : function-giving(areal analysis) on unit planning area by decision matrix of land suitability, check of typical characteristics of each function area and formulation of its future development strategies. Two alternatives were suggested as the areal analysis method, of which one is equal ordering / valuing technique of checking indices for land suitability classfication and the other preferential weighting technique. And then, under the algorithm specially defined in this study, land suitability maps(Fig.2,3) of the case study area (Seungju-county area, Chonnam-province, Korea) were drawn from the areal analysis results. By use of land suitability classification results, unique characteristics of typical function areas were defined (on 7 types of alternative 1 , 8 types of II ) and their future development strategies were formulated in the case study area, According to the categorization criteria in this study, all the villages of the case area were classfied as a suitable type of function areas illustrated in this study.

The access area, so called "core" in the housing block, makes a buffer zone between public open space and private interior space, as well as offers chances of communication for the users. Planning and design of this area, however, tend to be not attended, comparing with another spaces in the multifamily housing block. This paper is aimed at investigating examplary model European cases and, thus, finding out some positive and applicable planning skills for multifamily housing in Korea. This study covers following aspects; firstly, the important social meaning of core area was analyzed in comparison of Korea and Europe, secondly, intensive studies on the spots, visiting German, Austrian and Dutch cases, made it possible to grasp the prevailling tendency toward assessment of this area in the Continent, Thirdly, useful planning elements and skills by European examples for more user friendliness, more economization and raising the quality of spatial design and sequential experience were founded out with regard to various core types. and lastly, some concrete guidelines for planning are presented for the improvement of so far monotnousely designed core area in the local multifamily housing. Consequently those European cases made it clear that the planning of core area is closely related to the total design of housing blocks. This study maybe conducive not only to the planning of this area, but also further to the increase of the quality of life in multifamily housing.y housing.

When Binomial data are obtained, logit and logit mixed models are commonly used for small area estimation. Those models are known to have good statistical properties through the use of unit level information; however, data should be obtained as area level in order to use area level information such as spatial correlation or auto-correlation. In this research, we suggested a new small area estimator obtained through the combination of unit level information with area level information.

The purpose of this study was; to investigate consumers'selection criteria for their trade area when purchasing apparel products; to study whether there is a difference on the importance of the selection criteria; to examine consumers'willingness to visit specific trade area according to the types of apparel products. Four hundred sixty-nine female consumers who lived in the two new towns, Bundang and Ilsan participated in the study by completing questionnaires. Data were analyzed using factor analyses, t-tests, paired t-teats and chi-square analyses. The results indicated that consumer selected trade area based on shop variety within trade areas and range of products, customer services, environment of trade area, price level, entertaining features of the trade area, and the convenience of location and shopping time. In addition, the importance of these criteria varied according to the types of apparel products(i.e. formal wears and casual wears). The types of apparel products had influence on consumers'willingness to visit specific trade area. Consumers preferred the trade areas in the new towns for purchasing formal wears, whereas they frequented the trade areas in Seoul for purchasing casual wears.

The Khogno Khan mountain special protected area belongs to Khogno Khan subdistrict of Gurvanbulag district of Bulgan Province and is 46.9 sq.km. with its main feature being mountain forest zone. In this paper we present some results of research of the Anthropological and archaeological team of Mongolian Korean Joint research expeditions carryied out in Khogno Khan mountain special protected area from 27 July to 1 August, 2000. During archaeological reconnaissance we discovered around 27 localities of archaeological monuments belonging to different historical periods (from the Neolithic up to the Mongolian period, $13^{th}-17^{th}$ Century) in the territory of the Khogno Khan special protected area. Based on the results, we especially want to point out 1). The archaeological and historic monuments (from the Neolithic up to modern era) found in the Khogno Khan mountain and its surrounding area show that since the Neolithic period (around 8000 years ago) this area was occupied by the ancestors of Mongolians and it was used during subsequent historic periods on the one hand. 2). On the other hand the Khogno Khan mountain region was one area where there occurred intensive admixture between populations of Kurgan culture, Deerstone culture from the West Mongolia and the population of slab graves culture from Central and East Mongolia during Bronze and Early Iron Age. 3). Today the mountain is one of the area with a unique assemblage of archaeological monuments from different historic periods, what naturally seems like an open-air natural museum of Mongolian Prehistory.

The subject specialization room will be able to support university library users who are inclined to use the general reading room. This study is the research of the area planning for university library's subject specialization room. For the evaluation, 431 users from 15 university libraries in 14 universities located across Seoul were surveyed. Statistical analysis was performed using SPSS. Frequency, percentage, mean, t-test, f-test were used. Results of the study are as follow. Subject specialization rooms in university libraries can be classified via the analysis of spatial characteristics. According to the area ratio of data space and reading space in a subject specialization room, the subject room can be separated into data-loaning and data-reading types. Old libraries are more likely to be data-loaning types, where reading room is small and there are a lot of bookshelves. The annual increase in library collections causes space for bookshelves to decrease. As a result, space for reading has been gradually transformed into space for stacking data. It is necessary to introduce ways to maintain enough space for both reading and stacking data. One way includes movable compact shelving, which can partially replace existing fixed shelves.

Role of the perforated pipe is to drain the water with equal pressure and velocity through the holes of perforated pipe. The perforated pipe is being used in many processes of water treatment system, however, the design parameter of perforated pipe is not standardized in korea. In this study, we have found the design parameter of perforated pipe in the water treatment system using the Computational Fluid Dynamics (CFD). The uniformity of outflow from the perforated pipe is directly affected according to area ratio(gross area of holes/surface area of the perforated pipe). In other words, the uniformity of outflow is improved as area ratio is smaller. Also, at the same area ratio, the uniformity of outflow is improved as number of holes is increase. Specially, in case of the two holes per length of pipe diameter(2/D) shows the most uniformity of outflow and the best hydraulic with the smaller pressure drop. The uniformity of outflow is aggravated and the pressure drop of pipe is decrease as length of pipe is longer. In case of that pipe length is 10m and above, the pressure drop decreased about 30% when diameter ratio is 40% with 0.2% of area ratio by comparison with 0.1% of area ratio.
