This project is planned to grasp the present situation of traditional medicine part in our country and to study protection method about this by the intellectual property which is the international concerning point recently. Through this, we will be able to devise means to deal with protection method of traditional medicine being developed by WIPO now. Traditional medicine field In our country Is organized with specific condition separated into the part of institution and the part of non-institution. So, because of the closed peculiarity, we have experienced the difficulties to understand the real facts about traditional medicine. We cannot be indifferent to the matter anymore. Because the expectation of object people is high, we could expect the realization of research content. In 1 detail project, we investigated the situation of traditional medicine in our country through various collecting methods for excavation of oriental treatment technique and herb medicine which is worth protecting. With it, we sorted again into 56 kinds of 11 parts through analysis of validity in the way of oriental medicine. And we tried to link this up 2 detail project which is about legal and institutional guarantee concerning protection. furthermore, we tried to find approach ways for security of objectivity into 4 steps with the example of model disease. we could complete practical classification of traditional medicine in our country. In 2 detail project, we studied the protection method by the intellectual property through research result in 1 detail project. For this, we observed an outline of the intellectual property including a patent application analysis in folk traditional medicine part, and problems of traditional medicine protection and world trend by traditional knowledge protection tendency and the patent law In domestic traditional medicines, the aspects unprotectable with the patent law now were remained. So, we suggested supplementary plan. And we also suggested the freedom of utilization between traditional medicine possession countries (in-situ utilization) and the demand compensation payment for a third country (ex-situ utilization) in connection with international movement.

The purpose of this study was to find out the variation between molecular size distribution (MSD) of natural organic matter (NOM) in raw waters after different water treatment processes like conventional process (coagulation, flocculation, filtration) followed by advanced oxidation process (ozonation, GAC adsorption). The MSD of NOM of Suji pilot plant were determined by Liquid Chromatography-Organic Carbon Detection (LC-OCD) which is a kine of high-performance size-exclusion chromatography (HPSEC) with nondispersive infrared (NDIR) detector and $UV_{254}$ detector. Five distinct fractions were generally separated from water samples with the Toyopearl HW-50S column, using 28 mmol phosphate buffer at pH 6.58 as an eluent. Large and intermediate humic fractions were the most dominant fractions in surface water. High molecular weight (HMW) matter was clearly easier to remove in coagulation and clarification than low molecular weight (LMW) matter. Water treatment processes removed the two largest fractions almost completely shifting the MSD towards smaller molecular size in DW. No more distinct variation of MSD was observed by ozone process after sand filtration but the SUVA value were obviously reduced during increase of the ozone doses. UVD results and HS-Diagram demonstrate that ozone induce not the variation of molecular size of humic substance but change the bond structure from aromatic rings or double bonds to single bond. Granular activated carbon (GAC) filtration removed 8~9% of organic compounds and showed better adsorption property for small MSD than large one.

This experiment was carried out to select suitable organic matter in To-jik nursery (self soil nursery) for complement To-jik nursery's defects that are deterioration of raw material by poor quality of seed ginseng and reduction of the quantity in seed ginseng production. Organic matter used were Yacto, rice bean, defatted rice bran, soybean cake and their mixture. As follows, bulk density in soil physical property by treating organic composts was the greatest in soybean cake and the next was followed by mix, Yacto, defatted rice bran, and rice bran treatment in order. Soil pore space ratio was totally the opposite; that was rice bran the first and followed by defatted rice bran, Yacto, mix and soybean cake treatment. The incidence rate of damping off by treating organic composts was 1.5% in both soybean cake and mix while the others was 1.0%. Emergence time was the same among treatment on April 16 and Emergence rate was the highest at 73% in Yacto. There was no significant differences among treatment in the growth of aboveground part but it was a little better in defatted rice bran treatment. In Yacto treatment, the growth of underground part, total root number per kan, rate of first grade ginseng seedling, and rate of usable ginseng seedling etc. were entirely higher but there was little differences. Using defatted rice bran was slightly lower in productivity compared to Yacto, but the possibility was high as a alternative for Yacto in a view of managing cost down.

본 연구는 유기물 및 동일비료를 하해혼성 충적토 전북통에서 24년 연용 후 주구인 유기물(무시용, 볏짚, 퇴비)에 세구인 질소시비량(0, 100, 150, 200, $250kg\;ha^{-1}$)을 5수준으로 처리하여 년차별 토양화학성과 유기태 질소 및 무기태 인산의 형태별 집적량을 분석한 결과는 다음과 같다. 유기물 시용으로 토양산도는 다소 낮아졌으며 그 정도는 볏짚을 준 경우가 퇴비를 줄 경우보다 컸다. 토양 중 유기물 함량은 연차적으로 증가하는 경향을 보였으며 퇴비 시용 구에서 더 증가했다. 유효인산 함량은 관행(NPK)의 경우 감소하였고 유기물 시용으로 증가했으며 퇴비 시용 구에서 더 증가하였다. 토양 중 총유기태질소 함량은 퇴비>볏짚>무시용 순으로 높았으며 유기태 질소 중 산가용 비유출성질소(아미노산태 질소)>산불용성질소(미동정태질소)>산가용 유출성질소(아미노당태 질소) 순으로 많았다. 산가용 비유출성질소는 볏짚+질소시비에서 $918mg\;kg^{-1}$로 총유기태질소의 52.7%를 차지하였고 산가용유출성질소는 볏짚+질소 무시비, 산불용성질소 및 산가용 유출성질소는 퇴비+질소시비에서 많았다. 또한 토양 중 총무기태인산 함량은 볏짚+질소시비>퇴비+질소시비>퇴비+질소무시비>무시용+질소시비>볏짚+질소시비 순으로 많았다. 볏짚+질소 무시비에서는 무기태 인산이 모두 높았고 특히 Fe-P 함량이 $425mg\;kg^{-1}$로 가장 높았다. 퇴비+질소시비 및 무시용+질소시비에서는 Fe-P 및 Al-P 함량이 높은 반면에 질소 무시비와 큰 차이를 나타내지 않았다. Ca-P 함량이 볏짚과 퇴비 시용으로 높아진 것은 유기물의 인산집적 뿐만 아니라 토양환경의 변화 즉 환원이 높게 진행된 결과로 생각된다.

This study was carried out to investigate the cause of leaf discoloration occurring frequently in paddy cultivation. Chemical property of soil and inorganic nutrient component of leaf were analyzed on abnormal fields of 7 regions where leaf discoloration occurred severely and normal fields of 7 regions among ginseng garden. The pH of abnormal fields was strong acidic condition (pH 5.51) compare to normal fields of slightly acid condition (pH 6.42). Calcium and magnesium content in abnormal fields were lower distinctly than that of normal fields, while EC, organic matter, phosphate, and potassium content showed not distinct difference between abnormal and normal fields. Whereas calcium and magnesium content were distinctly high in normal fields, both of potassium and iron content of ginseng leaf were distinctly high in abnormal fields. In particular, iron content of abnormal fields was more 1.94 times in soil, and 3.03 times in leaf than that of normal fields. In soil chemical property, there were significant negative correlation between leaf discoloration ratio and soil pH, and there were also significant positive correlation between leaf discoloration ratio and iron content. In ginseng leaf, there were highly significant negative correlation between leaf discoloration ratio and calcium content, and there were also highly significant positive correlation between leaf discoloration ratio and iron content.

일제는 그들의 통치목적을 달성하기 위하여 우리 문화재에 대한 조사와 제도화를 하였다. 이러한 과정은 일본인 관료와 학자들을 중심으로 진행되었으며, 몇 번의 변화를 거쳐 체계화 되었고, 1916년에 제정된 "고적 및 유물 보존규칙"과 1934년에 지정된 문화재들은 현재 우리나라 문화재 정책의 시작점이 되었다. 이 글은 일제강점기에 조선총독부 주도로 진행된 문화재 정책을 문화재에 관한 전반을 심의하던 '위원회'의 인원 구성과 '문화재 목록'의 변화상이라는 관점에서 살펴보았다. 이러한 사항들은 다음과 같이 요약된다. 첫째, 조선총독부는 문화재 정책을 입안하고 결정하기 위한 심의기구로 '위원회(보존회)'를 두었는데, 제도와 인적 구성 면에서 조선총독부 관료를 과반 이상 두도록 하여 조선총독부의 정책이 관철되도록 하였다. 이 속에서 조선인은 극소수가 참여하였는데, 그들마저 형식적인 구색 맞추기였다고 볼 수 있다. 둘째, 조선총독부가 조사하여 목록화한 문화재는 목록화 계기에 따라 크게 세 시기로 구분된다. 첫 번째 목록(1909~1916)은 등 급제로 대표되는 세키노타다시에 의해 주도되었고, 두 번째 목록(1917~1933)은 대장법으로 대표되는 구로이타가쓰미에 의해 주도되었다. 구로이타가쓰미는 문화재 제도를 입안하고 목록을 공식화 하면서 세키노타다시의 영향에서 멀어지려 하였는데, 이러한 정황이 제도와 실제 목록 내용에서 드러나고 있음을 확인하였다. 세 번째 목록(1934~1945)은 1934년 지정문화재 목록으로 만들어졌는데, 이 단계에서는 세키노타다시의 조사 성과도 반영이 되었으며, 종전의 규정에서 제외되었던 현존사찰의 중요 문화재도 포함이 되었다. 이렇게 1934년을 기점으로 현재 우리나라 문화재 목록의 기본적 체계가 만들어졌다.

Mesoporous carbons with tailored pore size were prepared by using sucrose as the carbon source and silicas as the templates. The silica templates were obtained from a hydroxypropyl-${\beta}$-cyclodextrin-silica hybrids using ammonium perchlorate oxidation at different temperatures to remove the organic matter. The structures and surface chemistry properties of these carbon materials were characterized by $N_2$ adsorption, TEM, SEM and FTIR measurements. The catalytic performances of these carbon materials were investigated through the reduction of nitroaromatic using hydrazine hydrate as the reducing agent. Compared with other carbon materials, such as active carbon, and carbon materials from the silica templates obtained by using calcination to remove the organic matter, these carbon materials exhibited much higher catalytic activity, no obvious deactivation was observed after recycling the catalyst four times. Higher surface area and pore volume, and the presence of abundant surface oxygen-containing functional groups, which originate from the special preparation process of carbon material, are likely responsible for the high catalytic property of these mesoporous carbon materials.

Salt accumulated soil should be reclaimed to lower salt level for crop production. This study was carried out to investigate the characteristics of water flow and transport of mono and divalent solutes on salt accumulated soils with different head pressures. Saturated hydraulic conductivity was measured by constant and falling head methods with maintaining different head pressures. Saturated hydraulic conductivity was influenced by bulk density and organic matter contents in soils, but it had different elusion patterns between saline and sodic soil. While the quantity of water necessary for reclamation could be varies with soil type, it was considered that the supply of one pore volume of water was affordable and economic. Additional head pressure significantly increased the volume of leachate at a given time and it was more effective at low organic matter soils. The results indicate that additional head pressure would be one of the best irrigation practices on desalination method for salt accumulated soils.
