This paper is study on Dong-Eue-Bo-Gam(東醫寶鑑) Dong-Eue-Bo-Gam(單方門)that is written by Heo-Joon. When Heo-Joon worte Dong-Eue-Bo-Gam(東醫寶鑑) between 1596 and 1610, it was the time for the people's healthy to be threatened by all kinds of infections and malnutrition. Dong-Eue-Bo-Gam(東醫寶鑑) compiled Chinese medical books and our medical books that still exists systematically. Especially there was Dan-Bang-Mun(單方門), medical art that is to use only one herb, at the end of each chapter for the people to treat disease. There was Tang-Aek-Pyun the end of Dong-Eue-Bo-Gam(東醫寶鑑). In this part, as it says herbs in rural areas were written in details, it was easy for everyone to get herbs to prevent any disease and to treat their sickness. That's why I'd like to succeed to our senior doctors' spirit for the medicine. So I decided to study Tang-Aek-Pyun that is based on Dan-Bang-Mun in Dong-Eue-Bo-Gam(東醫寶鑑) and many herbs that refer to the 4th of Gang-Je-By-Geup(廣濟秘笈). Medicine that was introduced in Dan-Bang-Mun(單方門) was 860 kinds of medicine. Among them, I choose about 3 kinds of medicine that was used the most frequently.

Recently the attention of the trace elements in arisen to the biochemical importances and the biochemical significances have been discussed and shown by several workers. And also UN-narcotic Committee has shown that geographical difference of Optimum based on the produced area, would be significant on its contents of trace elements. The problem of Rice in Korea is urgently important on the nutritional and agricultural view points for the soil improvement of its production and for the betterment of health program. In order to check the adaptability of cultural problems to the different qualities of the with regards to the kinds of rice spieces and in order to know the comsumption of trace elements through rice, the contents of trace elements on 40 samples of the polished rice sampled from the different areas consisting in 8 kinds of rice species are studied on contents of Al, MN, Ni, Zn, Co, Cu and Fe in this paper. Though the further wide spread studies should be carried out. It seems that Al, Fe and Ni contents show little differences by the kinds of rices species and Cu, Al, Mn, Zn, and Ni contents show geographically little differences. But these differences are not significant statistically. The Co was not detected from the rice samples. It is not clear whether Co content in rice is a undetectable amount or the Co is absent in rice at all.

Carbonation and drying shrinkage are very important properties of concrete, that can cause concrete to lower its capacity and spall. But the research on them in high strength concrete is very poor. In this study, to estimate influences of W/B, the kind of admixture, the replacement ratio of admixture, fineness of blast furnace and etc. on drying shrinkage and carbonation, we make experiment with 3 levels(28, 35, 55%) of W/B, 3 kinds(blast-furnace slag, fly-ash, silica-fume) of admixture, 3 levels of the replacement ratio, 3 levels(4000, 6000, 8000cm2/g) of fineness of blast-furnace slag and 2 kinds of curing condition. As the results, compressive strength of concrete was decreased, as W/C was increased and the replacement ratio of admixture was increased. Drying shrinkage was increased, as W/B was higher, the replacement ratio of admixture was increased and fineness of blast-furnace slag was decreased. And carbonation was increased, as W/B ratio was higher, the replacement ratio of admixture was increased.

This study was carried out to research the influence of climatic conditions including wind direction, wind speed on air pollution in Seoul. The data were obtained from the 4 sites of air pollution monitoring stations in Seoul from '95 to '96, and analyzed statistically by SAS program. The results were as follows 1. The prevailing wind directions by season in each site were as follows Nangajwa-dong were showed SE in spring, fall, winter and WNW in summer. Ssangmun-dong were showed NW in spring, fall, winter and NNE in summer. Kuro-dong were showed SW in spring, summer, ENE in fall and NW in winter. Bangi-dong were showed WNW in four seeasons. 2. The concentrations of 5 kinds(SO$_2$, Dust, NO$_2$, CO, THC) of air pollutants were relatively low in west wind. In case of O$_3$ was opposite. 3. The concentrations of 5 kinds of air pollutants were increase with decreasing wind speeds. 4. The washing effects of air pollution by rain were significant. The concentrations of 5 kinds of air pollutants were high when the humidity were 61-80%, and low as it were 0-20%. In case of O$_3$ was opposite. 5. All of air pollutants concentrations but O$_3$ were high when the UV intensity level and temperature within the range of above zero were low level.

This study analyses influences on partial work rates under whole work rates on landscape constructions in Ulsan Grand Park. The schedule management is one of the factors that are very important to the process management of landscape construction. The time process of the whole construction is supposed to be affected by several kinds of work that organize the whole construction. First, this study divides the construction of Ulsan Grand Park into 10 kinds of works: earth work, rain and sanitary sewage water work, water-supplying work, planting work, paving work, water proofing work, fountain work, instituting work and temporary work. Then the time-process curves of all kinds of work are statistically compared to that of the whole construction. The trial methods of statistics are lineal regression, non-lineal regression, and principal analysis. In the result of the non-lineal regression, the rain and sanitary sewage water work, the water-supplying work and the earth work strongly affected the whole construction. The principal analysis results show that the whole construction is affected strongly by the water-supplying work, the rain and sanitary sewage water work and the earth work. However the lineal regression is shown to be senseless because of its high collinearity.

We have been optimized tungsten(W) plug CMP(chemical mechanical polishing) characteristics using two different kinds of component of slurry and two different kinds of pad which have different hardness. The comparison of oxide film roughness on around W plug after polishing has been carried out. And W plug recess for consumable sets and dishing effect at dense area according to the rate of over-polishing has been investigated. Also the analysis of residue on surface after cleaning have been performed. As a experimental result we have concluded that the consumable set of slurry A and hard pad was good for W plug CMP process. After decreasing the rate of chemical reaction of silica slurry and adding two step buffering we could reduce the expanding of W plug void however we are still recognizing to need a more development for those kinds of CMP consumables.

It is strongly believed that Video on Demand(VOD) will become one of the most promising services for Broadband Integrated Services Digital Network(B-ISDN). VOD service can be classified into two types of services: Near VOD(NVOD) and Interactive VOD(IVOD). Although VOD network requires many kinds of resources, we only consider video servers, programs. and storages. In the network. some video servers should be installed at some nodes(especially, at the root node for NVOD service). so that each node with video server stores video programs and distributes stored programs to customers. We take into account three kinds of costs related with the above resources: a program transmission cost, a program storage cost, and a video server installation cost. There exists a trade-off relationship among those three costs according to the locations of video servers and the kinds of programs stored at each video server. Given a multi-level VOD network and the total number of programs being served in the network. the resource. optimization problem for providing both IVOD and NVOD services is to determine where to install video servers, and which and how many programs should be stored at each video server, in order to minimize the total cost. In this paper we develop an efficient dynamic programming algorithm to solve the problem. We also implement the algorithm based on two different service policies assumed in this paper.

In order to develop new insulating materials for GIS Spacer using environmentally friendly insulating gas, three kinds of dispersed liquid nano composites of solid epoxy /nano layered silicate filled material were prepared. And the epoxy/nano/micro silica composite was prepared by mixing epoxy/nano 3 phr dispersion/4 kinds of filler contents(40,50,60, 70wt%). The electrical insulation breakdown strengths of the nano and nano/micro mixed composites were evaluated by using 8 kinds of samples including the original epoxy. The mechanical tensile strength of the epoxy / nano / micro silica composite were evaluated, also. The TEM was measured to evaluate the internal structure of nano/micro composites. As a result, it was confirmed that the layered silicate nano particles was exfoliated through the process of inserting epoxy resin between silicate layers and the layers. In addition, dispersion of nano / micro silica resulted in improvement of electrical insulation breakdown strength with increase of filling amount of dense tissue with nanoparticles inserted between microparticles. In addition, the tensile strength showed a similar tendency, and as the content of microsilica filler increased, the mechanical improvement was further increased.
