In January 1983, the writer visited a few universites in Japan to survey the recent trend of studies in cultural and social Sciences. At that time what I researched is as follows; In Japan, many a learned society has been organized and the research activities were very lively. Mass publication of scientific periodicals and prompt translation of foreign writings showed the maturity of scientific atmosphere. It true that their study of literature has been performed on the basis of positivism since 1930'. But now Structuralism which consider's literary works as one organic unity of parts became the main basis of literary studies. And, Learned Society of Educational Law has been organized in Japan. In consequence, the level of researches in educational law could be remarkably high. So, it is necessary for us to study the law of education. For, to make it better, we must know not only the universal principles of education but also specific ones derived from the peculiar characteristics of Korean education. At the same time, in Japan, Department of the Law of Industrial Administration was established in 14 universities including Japan University. And with the help of it, companies could improve the efficiency in dealing with judicial affairs related with industrial administration. So, to be a winner in the international trade competition, it is also required for us to study the judicial affairs of industrial administration.

李炯柱,文錫哉 한국전통의학연구소 1997 한국전통의학지 Vol.7 No.2

十全大補湯加味方과 抗癌 化學療法劑인 mitomycin C의 倂用投與와 관련된 寶驗을 施行하여 아래와 같은 結論을 얻었다. 1. Ascites form of Ehrlich carcinoma에 十全大補湯加味方抽出物과 mitomycin을 倂用投與한 結果 十全大補湯加味方 抽出物에 의하여 mitomycin C의 抗腫瘍倂效果가 약간 增加하는 경향을 보였으며,마우스의 平均 生存期間도 增加하였다. 2. Solid form of Ehrlich ascites carcinoma에서 十全大補湯加味方 抽出物과 mitomycin C를 倂用投與한 結果 單獨投與時 보다 抗腫瘍效果가 더욱 뚜렷하여 腫瘍의 크기를 顯著하게 減少시켰다. 3. Ehrlich ascites carcinoma cell의 lysosomal enzymes의 총 活性度는 mitomycin C의 單獨投興時 보다 十全大補瘍加味方 抽出物의 投與時 顯著하게 蒸加하였으며,mitomycin C와 十숲大補瘍加味方 抽出物을 倂用投與한 경우에는 더욱 顯著하게 增加하였다. 4. 十全大補瘍加味方 抽出淚으로 前處理時 NK細胞의 標的細胞와의 結合能은 물론 結合된 標的細胞의 融解能도 促進되었다. 以上으로 보아 十全大補瘍加味方 抽出物이 자체로는 顯著한 抗腫瘍效果가 없다고 할지라도 腫瘍을 發生시킨 마우스의 生存率을 增加시키고,抗癌化學療法劑인 mitomycin C의 細胞毒性 및 NK細胞의 活性度를 亢進시키는 것으로 思料된다. Mainly side effects of antitumor chemotherapy are fatigue, G-I trouble(such as vomitting, nausea, diarrhea) and reduction of medullary function etc. Differentiated from syndromes in oriental medicine, above symptoms are recognized to "Deficiency of both ki(vital energy) and blood". And SDT(Sipjeondaebotang) has been widely used in "Deficiency of both ki(vital energy) and blood". SDTG(Sipjeondaebotanggamibang) consists of SDT plus several herb medicines-these have antitumor effect and reduce chemotherapheutic side effect. This experiment was undertaken to study the effects of SDTG on chemotheraphy. The results obtained in this study were as follows: 1. Antitumor activities of the ethanol extract from SDTG(Sipjeondaebotang -gamibang) and MMC(Mytomycin) on ascitis form of carcinoma in mice is a little improved. Especialy mean survival times of the group of SDTG(200mg/kg) and MMC(O.1mg/kg) is improved over 50%. 2. When SDTG and MMC is administrated together, the weight of tumor is more decreased than MMC alone. 3. 'The effect of the ethanol extract from SDTG and MMC on the lysosomal enzymes in Ehrich ascites carcinoma cell are more significantly improved than MMC alone. 4. SDTG extract increases both NKcell conjugation and cyto-lysis against target cell. According to the above results it is recognized that SDTG increases the chemotherapheutic effect of MMC and the activity of NKcell.

이주형,강동진,원대희,이민호,배태성 大韓齒科器材學會 2000 대한치과재료학회지 Vol.27 No.3

This study was performed to investigate the effect of ZrO2 addition in borosilicate glasses on the mechanical properties of alumina-glass composites. Porous alumina compacts were prepared by slip casing and sintered at 1100℃ for 2 hours. Dense composites were made by infiltration of molten glass into partially sintered alumina at 1200℃ for 6 hours. Specimens were polished sequentially from #800 to #2000 diamond disk, and the final surface finishing on the tensile side was received an additional polishing sequence through 0.3㎛ diamond paste. Biaxial flexure test was conducted by using ball-on-three-ball method at a crosshead speed of 0.5 mm/min. Fracture toughness was measured by a single edge V-notched beam (SEVNB) method with 2.5×5×20 mm rectangular bar. To examine the microstructural aspect of crack propagation in the alumina-glass composites, Vickers-produced indentation crack was made on the tensile surface at a load of 49.0 N and dwell time of 15 sec, and the radial crack patterns were examined by an optical microscope and a scanning electron microscope. The results obtained were summarized as follows: 1. The minimum biaxial flexure strength was obtained with an addition of 2 mol% ZrO₂ in glass composition and strength values increased with the increase of ZrO₂ content. 2. The minimum fracture toughness was obtained with an addition of 2 mol% ZrO₂ in glass composition and toughness values decreased with the increase of ZrO₂ content. 3. Fracture surfaces indicated the frictional interlocking of rough surfaces left behind the fracture front.

Carbon materials, disordered carbon and KS6(graphite, Lonza), were studied as anode materials of lithium ion secondary battery. The disordered carbons were made from thermosetting resins (phenol resin, furan resin, acetylene resin and its mixed resin). The resins were carbonized in nitrogen gas at 1000℃. When the thermosetting resins were carbonized, an addition of lithium hydroxide improved capacity and cycle life, but decreased the efficiency of the first charge/discharge. Also, in this study, the capacity of the carbon from phenol resin was higher than that of the carbon from acetylene resin or furan resin. But, the carbon from mixed resin was the highest capacity of all the synthetic carbons.
