The number and distribution of the retinal ganglion cells in the rabbit was determined from whole flat mounted preparations stained with methylene blue and thionin. The results were summarized as follows. 1. The total number of retinal ganglion cells was estimated to be 903,600 in retina ranging from 641㎟ in total area. 2. The number of alpha type ganglion ceils(above 15 microns) was 118,000 in the retina of rabbit and constituted 13% of the total cells. 3. The visual streak was recognized above 2.5mm from optic disc and ganglion cell density drops off rapidly above and below the visual streak. 4. Area centralis(8,300/㎟) was recognized at the area of 10mm temporally, from the point of 2.5mm superior to the optic disc. 5. The relative frequency of the alpha type ganglion cells was higher in the superior-nasal quadrant than in other region of the retina.

Kye Yongmook wrote 45 short stories from 1924 to 1950. His fiction writing training started with the reception of aestheticism, technicalism and nihilism through the literary journal The Creation. He clung to technicalism and nihilism to the end, while seeking after aestheticism, and realism from time to time. He viewed the lives of all the people of his days as tragic, and tried to depict those who fell into tragic plights in all his works. The whole period of his creative life can be divided into three: first, from late 1920s to early 1930s, second, from late 1930s to early 1940s and third, after the National Liberation. In the first period, he pursued literary realism in his stories, where he depicted the farmers who fell into tragic situations because of the barrier of class distinctions. In the second period, his works were oriented towards aestheticism, portraying diverse people who fell into tragic plights because of various obstacles including diseases. In the third period, he came back to realism, and described the national tragedy caused by the contradictions after the Liberation. But there is no character who gets out of the tragic situation in his stories, as he/she does not analyse its causes, nor try to find a way out, nor fight actively to escape from it. It resulted from the facts that Kye Yongmook, the writer, couldn't recognize the reality of his days deeply, and lacked in the unique insight of life. Consequently, Kye Yongmook stopped writing fiction at the early age of 46 in spite of good health without leaving many good works, for he didn't have an eye for the national realities and lives of the people, and couldn't develop new sources for literary creation. Thanks to the two of his works, “Adada, the Idiot” and “Counting Stars”, which can be evaluated as well written, he has been regarded as a writer who should be recorded in the modern fiction history of Korea, though he cannot belong to the main writers' group.

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.

十全大補湯加味方이 抗癌化學治療劑의 抗腫瘍效果 및 腫瘍細胞의 lysosomal enzymes에 미치는 影響

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.

Zero to tension fatigue tests and strain controlled fatigue tests were carried out to find how initial strain induced martensite, α' affects low and high cycle fatigue behavior and fatigue crack growth mechanisms. Microscopic study and phase analysis were carried out with TEM, SEM, EDAX, Optical Microscope, Ferriscope, and X-ray diffractometry. The amount of Initial α' was controlled from 0% to 33% by controlling the temperatures for cold working and heat treatment. Lower contents of initial α' showed higher fatigue resistance in low cycle fatigue but lower fatigue resistance in high cycle fatigue because it is ascribed to the more transformation of α' martensite during low cycle fatigue and higher ductility. In high cycle fatigue, fatigue life is attributed to the strength and phase transformation of austenite into α' during fatigue was negligible. γ boundary, γ/twin boundary, and γ/α' boundary were found to be the preferred site of fatigue crack initiation.

이호근,현형환,오두환,유주현 연세대학교 산업기술연구소 1990 논문집 Vol.22 No.2

The microorganism which produces Cepholsoporin C, has been selected from Cephalosporium acromonium by U.V radiation. Among the mutants, Cephalosporium acremonium var. M-10 was showed the highest Cephalosporin C productivity. On the basis of physiologieal characteristics, the difference hetween Cephalosporium acremonium var. M-10 and Cephalosporium acromonium was that the mutant did not assimilate sodium acetate, potassium nitrate, sodium nitrate. By using Cephalosporium acremonium var. M-10, the optimum conditions for the production of cephalosporin C on the rotary shaker were pH 7.0 soluble starch 4.0 w/v%, (NH₄)₂SO₄0.75w/v%,, CaCl ₂w/v%, soy bean meal 2w/v%, oleic acid 0.09w/v%, methionine 0.3w/v%, at 30℃ for 120 hours, respectively. On the study of time course, it revealed that the peak appeared at the stationery phese. The amount of Cephalosgorin C produced in this medium by mutant was about two times larger than that by Cephalosporium acremonium.

李注衡,朴仁熙,韓點洙,金文基,朴晋泰 慶北大學校 1983 論文集 Vol.36 No.-

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.
