Phage血球凝集反應에 必要한 phage量에 對하여

李賢澤 中央醫學社 1967 中央醫學 Vol.12 No.3

The author has investigated the effect of phage dose on phage hemagglutination. For this experiments, the klebsiella pneumoniae type 2, klebsiella phage and goat red cells were used and obtained the following results. For producing of the cold and warm phage hemagglutination, the more phage dose, in adsorption tube, than 106/ml and 108/ml was necessary respectively and, in the less dose of phage than that, phage hemagglutination was not produced even though higher concentration of serum was used. For producing of phage hemagglutination in the presence of 1:800 of stock serum of which K value is about 190min.-1, the more adsorbed phage particles, per sensitized red cell, than average 100 were necessary.

이용자 수에 다른 혼잡분석 - 대구시 달성, 중앙공원을 대상으로-

이현택 한국조경학회 1990 韓國造景學會誌 Vol.18 No.2

도시공원의 혼잡에 관해 실제 이용자가 느끼는 혼잡정도와 이용밀도를 중심으로 조사한 결과 다 음과 같이 요약할 수 있다. 이용밀도는 계절과 요일에 따라 큰 차이가 있으며 외국에 비해 상당한 과밀이용을 나타내고 있었다. 이용밀도와 혼잡간에는 높은 상관성을 보이고 있으며 고밀도에서 이용자가 증가할 때 보다 저밀도에서 이용자가 추가될 때 혼잡도에 더 큰 영향을 미쳤다. 이용자가 증가 하여도 혼잡에는 크게 영향을 미치지 않는 혼잡포화점에서의 1인당 공원이용가능 면적이 약10$m^2$로서 우리민족의 밀집공간에 대한 강한 내성을 나타내었다. 앞으로는 본연구에서보다 다양하고 폭넓은 공원녹지를 대상으로 한 실증적 연구가 뒤따라야 할것으로 생각된다. This survey was carried to determine the crowd In the city parks on the basis of the crowding and using denSity. The using density was vary different by season and day, and the density was much higher in this experiment than in the case of the foreign countries. This survey shows a high correlation between the using density and crowd as the crowd level was more influenced by the increasing number of park - users in the case of low using density than the high using density. The possible using space per individual was around 10㎥ in the parks, which means a strong endurance of the surveying group to the massing space, in the saturated crowding value that the crowd was not significantly affected by the increasing number of users.

This study deals with the degree of enclosure on the Court Space in 'Suh-Won' that has warious perceptual composition elements. 1. The size of Court Space in which we can read the complexion of others and easily understand every behavior of them is similar to that of the 'Madang' in the Korean traditional houses. 2. The angles of elevation are within the range of suitable enclosure as going from the center of the court Space to 'Kang-Dang' and the space -from the center of the Court Space to 'Kang-Dang'- is restricted and surrounded. It is also within the range of the least enclosure as going from the center of the Court Space to the 'Mun-Ru'. 3. The degrees of enclosure based on the horizontal angle are within the degree we can perceive the objects of structure easily. 4. The degree of enclosure based on the ratio D/H is increased as approaching from 'Mun-Ru' to 'Kang-Dang'. The distance as approaching from 'Mun-Ru' to 'Kang-Dang' is changed from social distance to personal distance. To conclude this the Court Space in 'Suh-Won' represents the hierarchical system with variety and the degree of enclosure and the size of space are within the range of human scale.

李鉉澤 경북대학교 1985 論文集 Vol.40 No.-

In order to obtain basic data for planning city parks, citizens' utilization of Dalsung park, the first park of Tague, was investigated. The results obtained are summarized as follow; Motive of visiting, activities in the park, and desired types of park were questioned to the Dalsung park visitors. Answers highly evaluated the forest and quiet rest space-indicating citizens' strong demand for nature. The majority of the users (79%) were visiting with friends or family suggesting that planning parks for group visitors would be necessary. Residents within a radius of 2 to 5 km around the downtown and 6 km around Dalsung park visited the park most frequently. About 80% of the visitors spent about 30 minutes to get to the park from home indicating that an inducement distance in time of Dalsung park would be 30 minutes. There was a large fluctuation in number of visitors by month and season. It suggests that park service should be improved to attract vistors all seasons. Many of the visitors over 50 years old were visiting the park everyday and those less than 50 were visiting the park once or twice a year. It means that many of the old visitors are everyday visitors.

李鉉澤 慶北大學校 1986 論文集 Vol.41 No.-

Yearly, monthly, and daily in a week changes of visitos at Dalsung and Jungang parks were investigated on the basis of the number of visitors at the two parks in Taegu city from 1970 to 1985 and the results obtained were as follows. The number of visitors was decreasing from the peak in 1978 in both parks. This phenomenon could be attributed to the development of the new parks such as Duryu, Mangoo, Apsan etc. Monthly change of the number of visitors at Dalsung park in 1980's shows a distinct difference from that in 1970's. The number of months in which the number of visitors exceeded the annual average shifted from 5 in 1970's to 4 in 1980's indicating more concentration of visitors in a few months. The number of visitors in April and May exceeded a third of the yearly total and the visitors in December, January, and February was only 9 to 13% of the yearly total, thus, indicating that visitors were concentrated in spring. Daily change in the number of visitors could be divided into weekday and Saturday, and Sunday at Dalsung park, in contrast with weekday, Saturday, and Sunday at Jungang park. The proportion of the weekday visitors was higher in Jungang park (0.3-0.4 by index) than in Dalsung park(0.25-0.3). The number of Sunday visitors at Dalsung park was 38% of the average week total in comparison with 30% at Jungang park. Thus the degree of concentration of visitors on Sunday was higher at Dalsung park than at Jungang park. In daily fluctuation in a week of visitors at Dalsung park by season, a relative index of weekday visitors to Sunday visitors was 0.22 in spring, 0.34 in summer, 0.26 in autumn, and 0.37 in winter. The degree of concentration of visitors on Sunday was about 50% higher in spring and autumn than in summer and winter, and about the same between spring and autumn, and between summer and winter.

이현택,이철희 한국조경학회 1990 韓國造景學會誌 Vol.18 No.2

The purpose of this study is to establish better residential environment in APT. complex. In this study, the actual conditions of exterior space, user behavior and degree of satisfaction are investigated and analyzed on the 5 high-rise story APT complex in Taegu city. The results of this study were as follow ; The size and arrangement of organizational elemnnt to exterior space in APT. complex have been regulated by law and regulations as the buildings coverage and floor space index, but housinghold and accessibility to the racility will be simultaneously considered to raise Quality of the residential environoment. The main user behavior to exterior space in APT. complex was practical activity and the user behavior pattern by week and among APT. complex were found similiarly. In the ratio of use to exterior space in APT. Complex, that of high-rise residents were lower than that of lowrise residents. In the degree of satisfaction by property of variables to exterior environment In APT. comples, physical of buildings, social - psychologic, managerial economical, physical property of exterior space were estimated positively, but properly of facility were estimated negatively. The degee of satisfaction to exterior environment in APT. complex was highly Influenced by green space, site size. As a result of ractor analysis, the four factors were drawn out from exterior environment in APT. complex. and the factors that have an effect on the degree of residents' satisfaction by factorscore were found in the order of importance as fallow ; managemental, physical, environmental, organizalional factor. Therefore, devilopment of APT. complex should be considered in a view of environmental psychology according to physical organization for used in the future. It is recommended that this problems should be necessitated to be more deeply studies in the future.
