Mt. Sulak is located on the border of Yangyang and Rinje Gun, Korea(38˚8′ N, and 128˚28′ E.). Mr. Sulak is the highest mountain of the Taiback Mountains which run Korean Peninsula from north to south and the peak Taichoug is the highest of it (above the sea level 1709m.). The Plants of Mt. Sulak have been first collected by Dr. T. Ishitoya & TaiHyun Chung in October 1923 and the first study of this mountain was Dr. T. Nakai's survey of Spiraea pubescens var. lasiocarph Nakai in 1928^⑼ The flora of this mountain has been partly surveyed by many scholar, but no one has ever surbeyed the entier flora of this mountain and as an first attempt toward it Tai-Hyum Chung & Il-Koo Lee published 109 families, 305 genera and 642 species(contained varieties and formae) in 1959. ^(23) The writers are now presenting as the results of survey of 1962 (July 30-August 5) and synthetieal survey of the theories which have been published till today. The results of this study are as follows: (1) The plants of Mt. Sulak are composed of 127 families, 376 gebera, 758 species, 181 varieties, 14 forma and 812 Kind in all.

A Study on Protection of Maternal Antibody against Hantavirus in Rats

우영대,--,--,--,--,-- 대한의생명과학회 2005 Biomedical Science Letters Vol.11 No.1

The etiologic agents of haemorragic fever with ranal syndrom (HFRS) in Korea are Hantaan and Seoul virus in the genus Hantavirus, family Bunyaviridae. In order to elucidate the role of maternal immunity to Hantavirus infection in rats, the protective effect of the maternal antibody were studies by using rats experimentally infected with Seoul virus strain HR80-39. Antibody titers of sera and viral antigen against Seoul virus were investigated by indirect immunofluorscence antibody technique (IFA). The dam sera had IFA antibody titers ranging from 1:128 to 1:1,024 after parturition. In fetuses, IFA antibody titers ranged from 1:16 to 1:64 just after birth, increased to peak titers ranged from 1:256 to 1:1,024 in the 2nd week after birth. Challenged newborn rats had IFA antibody titers ranging from 1:64 to 1:1,024 after inoculation. No viral antigen was detected in lungs or other organs of the newborn rats. The maternal antibody to Seoul virus was transferred prenatally through placenta and postnatally via colostrum from immune dams to their offspring. These results demonstrated that maternal antibody to Seoul virus was quite effective in protecting newborn rats against same virus infection.

濁酒 原料의 交替 方案에 關한 檢討 : 特히 고구마와 옥수수 原料의 利用에 關하여

李泰雨 西原大學校 1977 西原大學 論文集 Vol.6 No.-

밀가루가 原料인 現在의 濁酒를 고구마와 옥수수 原料로 交替시키려는 實驗 結果를 要約하면 다음과 같다. 1. 고구마를 原料로 할 境遇 가장 큰 問題点인 多量의 methanol 生成은 麥芽酵素에 依한 糖化와 瀘過工程을 거치게 하므로서 그 生成量을 0.2% 程度로 줄일 수 있었다. 2. 純고구마 原料만으로 濁酒를 製造할 境遇 酸味의 不足等 관능이 떨어지나 Asp. kawachii에 依한 粒麴法에 依해 酒母을 製造하고 고구마 糖液을 이단사입 시키면 좋은 관능을 보인다. 3. 고구마를 濁酒의 原料로 使用할 경우 糖化및 瀘過工程은 大單位化되어야 한다. 4. 밀가루를 酒母로 混用하는 境遇 고구마 濁酒의 原料 交替率은 50~80%로서 좋은 관능을 보인다. 5. 고구마 濁酒의 境遇 옥수수를 酒母로 混用하면 관능이 좋지 않다. 6. 옥수수로서의 原料 交替는 現行 使用되는 濁酒 製造 方法으로 可能하나 관능을 考慮하면 밀가루 混用으로 原料 交替率은 30~50%이다. 7. 옥수수로서 原料 交替를 할 境遇 密開式의 分麴 使用法이 좋았다. Tackju a brewing substrate was converted into wheat powder from rice for a food economic plan after the Korean War. Now, Tackju brewing substrates were also attempted and converted from sweet potatoes or corn powder. The results are as follows; (1) Using sweet potatoes for Tackju substrate, by amylolitic enzymes ofmold, large qwuantities of methanol was fermented in the Tackju mash. But sweet potatoes were saccharified by barley enzyme, and press filtered out impurities(as cellulose or pectin) after saccharfied. Methanol was fermented at a very low concentration below 0.2 percent. (2) If Tackju was brewed with sweet potatoes only, the taste is insipid and it is sourless. But Asp.kawachii were cultured by means of Lipkuk with wheat powder for one stip brewing, then the saccharified sweet potato solution was fermented for the main brewing, this problem could be totally solved. (3) Using sweet potatoes for Tackju brewing substrate, and saccharification process and filtration have to be mass produced in a brewery. (4) When seed yeast were cultured with wheat powder Lipkuk for one stip brewing, the possible rate of conversion to the sweet potatoes with good taste was 50 to 80 percent. (5) If the seed yeast were cultured with corn powder Lipkuk, the taste was not favorable. (6) Corn powder could be sacharified at the present Lipkuk method by amylolite enzymes of mold, with consideration of taste, wheat powder and corn had to be mixed. The possible rate of conversion to corn powder was 30 to 50 percent. (7) when corn powder was brewed for Tackju, the Bunkuk method in closed fermentation tank were best.

The study aimed to identify leaf sheath through the investigation a characteristic of leaf by planting depth and leaf sheath function through the investigation of effect of leaf sheath removals on growth and flowering in forcing of Lilium cultivars. The number of leaf sheath of 'Jolanda', 'Dream Land', 'Casablanca' were 6, 5, 11 in 0㎝ planting depth and 6, 5, 14 in 6㎝ planting depth. The number of leaf sheath in 'Jolanda' and 'Dream Land' were little different in according to planting depth. The other hand, the number of leaf sheath in 'Casablanca' were increased 3 when it were planted in 6㎝ planting depth. As leaf sheath were removed, plant height and stem root growth were decreased in 'Le Reve' and 'Casablanca'. Whereas the growth of basal root and flower number varied among of Lillium and stem diameter, the days of flowering and flower size were little different.

土壤酵素와 環境要因과의 相關

李泰雨 西原大學校 1990 西原大學 論文集 Vol.25 No.-

총세균수, 비공생성 호기성 질소고정균수, 眞菌數와 amylase활성을 각 입지의 토양에서 측정하고, 이들과의 관계와 토양한경요인의 영향을 검토하였다. 각 균량은 주로 토양의 수분 함량과 유기물함량에의하여 그 크기가 결정외었으며, 각 균군의 크기의 크기와 토양효고활성가는 양의 상관을 나타냈다. 특히, 비공생성 호기성 질소고정균량 및 眞菌의 량과는 상관이 높게 나타났다. 토양요인과 효로활성과의 관계는 계절괴 입지에 따라 차이가 있으나 전체적으로 볼 때 토양유기물함량과 높은 성관을 보였으며 토양수분량은 30-40%에서 효소활성이 가장 높았다. 이러한 관계로 볼 때 토양효소는 토양미생물이 직접 또는 간접적으로 생산 공급하며, 토양요인은 토양미생물군의 크기를 제어함으로서 토양속의 효소량 및 활성에 영향을 주는 것으로 판단된다. 한편 토양 amylase의 활성은 초지에서 보다는 관목 또는 교목림의 토양에서 높은 경향을 보였으며, A층이 B층 보다 큰 활성을 나타냈다. 그러나 춘계 및 추계에는 A층과 B층의 역전도 있었다. The number of total bacteria, aerobic free-living N -fixing bacteria and fungi were determined, and soil enzyme activities of amylase were measurd in different stands. And the relationships between the number of each microbial group, soil enzyme activities, and soil factors were examined. The relation of the amount of each micorbial group with soil organic matter and water content showed higher correlation than with soil pH. The changes of soil amylase activities were chiefly affected by soil organic matter content rather than other soil factors, and highly correlated with the number of fungi and aerobic free-living N-fixing bacteria. Consequently, it can be concluded that soil microbial organisms were the direct or indirect source of soil amylase, and the soil amylase activities were varied. Soil amylase activities were higher in the tree forest stands and A soil layer than in grass stands and B soil layer. In springs or autumn, enzyme activities of each soil layer were conversed occationally.

The effect of non-point source pollution in rural area has much influence on the stream water quality. It is difficult to improve the stream water quality, because of complex pollutant loads technically and because of treatment-cost of the deteriorated water economically. The best way to reduce the non-point source pollution is to check the water quality in the inlet of irrigation channel and control the water quality in the outlet of drainage channel. Stream water quality in the rural area is closely related with the fertilizers, pesticides, and livestock wastewater. Basically the rate of treatment and retention time were estimated for BOD, COD, SS, NH₄-N, T-N, NO₃-N, T-P, PO₄-P using materials such as gravel, crushed stone, useless tire, geotextiles, and concrete block, respectively and also using the combined materials. The rate of treatment for BOD, COD, SS is high, but that for NH₄-N, T-N, NO₃-N, T-P, PO₄-P is low. Optimal retention time in the natural contact channel was 90 minutes.

巨文島 植物調査 硏究

鄭台鉉,李愚喆 成均館大學校 1966 論文集 Vol.11 No.-

巨文島는 韓半島의 南端, 東經 127°16′30″∼127°24′50″, 北緯 34°0′∼34°0′4″에 位置하며 古島, 東島, 西島의 3個 有人島와 10餘個의 無人島로 되어 있다. 本島의 植物이 最初로 採集된 것은 1960年에 Wilford(英國王立植物園 專屬採集人)이였다. 그의 採品은 Hooker 博士에 依해 發表되었다. 그 뒤에 國內外의 多數의 學者가 本島를 찾았으나 部分的인 發表가 있을 뿐이고 完全한 植物相이 밝혀즌 바 없다. 筆者들은 1965年 8月 5日∼8月 14日 사이에 本島의 植物을 調査하였으며 오늘까지 旣發表된 것을 綜合하여 發表코자 한다. 1. 巨文島의 植物은 107科 353種 10變種이다. 2. Ranunculus Vernyi Fr. & Sav.(왜젓가락풀)와 R. Tachiroei Fr. & Sav.(개구리미나리)와 混同되어 오든 R. cantoniensis DC.(민개구리미나리)를 區別할 것을 主張한다. 이는 全形은 前者와 類似하고 果實은 後者와 類似한 種이다. 3. Brachypodium sylvaticum (Huds.) Beauv(산개밀)와 Koelreuteria paniculata Laxmann(모감주나무)이 이곳에 分布함은 分布上 興味가 있다. Ir. Keamoon (Port Hamilton) is located on southernpart of Korean Peninsula (127°24′50″∼127°16′30″E. and 34°0′4″∼34°0′0″ N.), and contains three inhabited islands (Go-do, Dong-do, and Su-do) and about ten uninhabited islands. Since Wilford, collector of Kew Botanical Garden in England, collected this island's plants in 1960 and Dr. Hooker published those, many scholar has partly surveyed the flora of this island, but no one has ever surveyed the entier flora of this island. The writers are now presenting this study as the results of survey of 1965 (Aug. 5∼14) and synthetical survey of the theories which have been published till to day. The results of this study are as follows: 1) The plants of Ir. Keamoon are composed of 107 families, 353 species, 10 varieties and 363 kind in all. 2) We maintain that Ranunculus cantoniensis DC. is distingushed from R. Vernyi Fr. & Sav. and R. Tachiroei Fr. & Sav.; it is resetmble to the former in full form and the later in fruits. 3) That Brachypodium sylvaticum (Huds) Beauv. and Koelreuteria paniculata Laxmann are distributed on this island is very interested in view of the distribution.

土壤내에 分布하는 好氣性 菌群의 變動에 關한 硏究

李泰雨,沈載國 西原大學校 基礎科學硏究所 1991 基礎科學硏究論叢 Vol.4 No.-

The effects of soil factors, climatic changes, and artificial soil temperature and water content on the fluctuation of population size of each soil microbial group were studied at different stand, such as lime soil, bamboo forest soil, alpine grassland soil, and developed deciduous forest soil from 1982 to 1990. The population size of each microbial group showed the minimum at winter season, the increase soon after thawing of early spring and the maximum at summer season. The annual fluctuation of each soil microbial population size mainly depends upon the seasonal changes of soil temperature. The population size of each soil microbial group showed the difference in accordance with soil organic matter content and pH at each stand. In oak forest soil, about 4 to 7 times larger microbial population than the pine forest soil. The vertical distribution of soil bacteria was decreased with the depth of soil and the changes of bacterial pupulation was significantly correlated with soil organic matter content. In artificial soil condition, 10℃ increasing of soil temperature give rise to about 10 times increase of microbial population as well as the relationships between annual changes of soil temperature and microbial population size.
