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.

Let H^∞ denote the Banach algebra of bounded analytic functions on the open unit disc and M(H^∞) denote its maximal ideal space. In this paper, we show that a sequence {z_(n)} of points in a Stolz angle formed by two rays from a point on the unit circle with |z_(n)|↑1 is an interpolating sequence if inf_n ρ(|z_(n)|, |z_(n+1)| >0, where ρ is the pseudohyperbolic metric defined on the open unit disc. The Shilov boundary ∂ of H^∞ is a proper subset of M (H^∞)-Δ(Δ is the set of all point evaluations) and ∂ can be identified with the maximal ideal space of L^∞. It is shown ∂ that is the set of all homomorphisms of H^∞ on which all interpolating Blasckke products have modulus 1.

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.
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 permeability and diffusivity of H₂, He, O₂, N₂, and CO₂in cellulose acetate membrane have been measured at temperatures from 10 to 60℃ and pressures up to 6Kg/cm². The membrane was prepared by casting cellulose acetate solution on a glass plate. In this process, the effect of evaporation time on characteristics of the membrane was discussed. The data for the gas diffusivity were obtained by the time lag method. At a given temperature and pressure, difference, the permeability and diffusivity were constant regardless of the increased of pressure difference, but increased exponentially with the increase of temperature. As the square of the gas molecular diameter increased, the diffusivities decreased exponentially and the activation energy for diffusion increased linearly. Much of the observed scatter in these correlations is attributable to uncertainty in the method of defining molecular diameters. On the other hand, the heat of solution decreased linearly with Lennard Jones force constant. With the exception of H₂and He, it is found that dissolution of the gases into the membrane was exothermic.

Recently, small and medium sized cities are to be a new limelight in developing countries. Because, they have performed important roles in promoting are spreading economic and social development of the country. I can assert that it is the optimum time to smooth out difference between regions, to activate local small and medium cities at this time. Because the recognition against polarization reversal on the dispersal policies than the first stage of the powerful trend of concentrative development. This study is concerned with all small and medium sized cities in Kore.a, and has two main purpose. First one is to select the general analysis variables affecting urban growth from existing theoretical literatures, Second one is to identify the dominant factor and their change for the growth of small and medium sized cities in Korea through the analysis of correlation with growth rate. The basic goal of this treatise puts on emphasize to issue the problems through looking into realities and functional roles of small and medium cities in the urban system for the past 10 years in Korea, to find out alternative method in order to activate the strengthening of foundation and functional activity of local small and medium cities by analyzing the relevancy between functional character and growth potentiality of individual cities.
韓國內에 自生하는 Bacillus thuringiensis의 分布와 同定
李泰雨 西原大學校 1987 西原大學 論文集 Vol.20 No.-
한국의 토양, 낙엽, 퇴비, 제비의 배설물, 누에의 배설물, 곤충의 유충 등을 수집한 218개의 표본으로부터 crystaliferous particle을 생산하는 균주 약80주를 분리하여 그중 조사된 11주에 대한 보고하고자 한다. Youngju 85-SW-4는 구상의 crystaliferous particle을 생산하고, 휜불나방의 유충에 대해서도 60-80%의 독성을 나타내거나 형태 및 혈청학적 소견에서 B.thuringiensis 가 아니었다. Andong 85-BO-1, Andong 85-BO-5, Andong 85-BO-8은 모두 능형의 crystal을 생산하고 혈청학적으로 같았으며, Andong 85-BO-3과 Andong 85-BO-5는 plasmid DNA의 수와 이동거리가 거의 유사하였다.그리고 Andong 85-BO-1은 plasmid DNA의 이동거리가 var. aizawai 보다 특히 var. Rurstari와 더 유사하였다. 능형의 crystal을 생한하는Yechon 85-BE-9는 var. alesti 의 근연종이며, Seoul 85-So-7은 crystal의 형태가 var. Ryushuensis와 같은 등근모습이며, plammid DNA도 유사하였다. 점모양의 작은 crystal을 드물게 생산하는 Sorak 85-LI-6, 능형의 crystal을 생산하는 Youngju 85-SW-5, Andong 85-BE-8은 서로 상이한 plasmid DNA상을 나타냈다. 그러므로 조사된 11개의 균주는 7-8개의 서로 다른 균주임이 밝혀졌으며, 한국에도 여러 종류의 Serovar.가 분포하고 있음을 알 수 있다. About 80 strains of crystaliferous particle producing bacteria were isolated from 218 samples of soil, litter, composed, swallow extrecta, Bombyx mori and its extrecta, and insect larvae which were collected in various site of Korea. 11 strains were investigated morphology of spore and crystaliferous inclusion, toxicity for Bombyx mori, Hyphanteria cunea, Drosopila melanogaster and larvae of Mosquitoes, and immunoreaction and plasmid DNA by reference strains. Nevertheless, Youngju 85-SW-4 produced round-shaped crystals and revealed high lethal rate for Hyphanteria cunea, which was determined that Youngju 85-SW-4 was not B. thuringiensis by morphological characters of spore and immunoreactions by reference strains of B. thuringiensis and B, moritai. And the others were agglutinated by reference strain of B. thuringiensis and were not agglutinated by B. moritai. The crystal's shape of Sorak 85-LI-6 was small and rounded-shape and crystals were produced rarely, and Seoul 85-SO-7 was rounded or rozenged-shape. The others, that is, Yechon 85-SO-9, Youngju 85-SW-5, Andong 85-BO-1, Andong 85-BO-3, Andong 85-BO-5, Andong 85-BO-6, Andong 85-BO-8, were rozenged-shape. Andong 85-BO-1, Andong 85-BO-5, and Andong 85-BO-8 were determined same strains by immunoreactions. And Andong 85-BO-3 were similar with Andong 85-BO-5 by migration lengths and total DNA elements of plasmid DNA. The case of Andong 85-BO-1 was more similar to var. kurstaki than similar to var. aizawai and Yechon 85-BE-9 was almost the same as var. alesti by plasmid DNA. And in case of Seoul 85-SO-7, the round-shaped crystal was the same as var. kyushuensis and the pattern of plasmid DNA was also similar. Sorak 85-LI-6, Youngju 85-SW-5, and Andong 85-BO-8 were revealed different characters by immunoreaction and plasmid DNA. As a result, 11 Isolates were determined to 7-8 different subspecies and then, multi-serovars of B. thuringiensis were distributed in Korea.
