Coronary artery calcification(CAC) is found frequently in the atheromatous plaques. CAC is known to have increased frequency above 40 years. CAC without evidence of atherosclerosis in young adults is quite rare, however, CAC combined with aneurysms in young adults have been infrequently reported in patients with a past history of a Kawasaki disease in child. We report an autopsy case showing CAC and aneurysm in the absence of macroscopically identified atherosclerotic lesions in a healthy 23-year-old man. The autopsy examination revealed aneurysmal dilatation of the right coronary artery, which was connected with calcified lesion. A calcified lesion of the left anterior descending coronary artery was aslo noted. Microscopically, aneurysmal wall was non-specific except for hyalinized wall and foci of calcification. A striking histologic finding of calcified mass was ring calcification along the wall of the coronary artery. Antecedent Kawasaki disease in the past was suggestive as other reports.

嶺南地域의 人口高齡化와 老年人口의 空間的 分布變化

金永直 대구효성 가톨릭대학교 1994 연구논문집 Vol.48 No.1

Youngnam area has the highest proportion of aging population in Korea. As a general trend in Korea, Its aging in population also results from demographic and social, economic factors. Demographic factors are low rate of death caused by improvement of national income and living conditions, medical development and improvement of health and sanitation, and prolongation of the average span of life,, and low birth rate by the population policy. And social, economic factors are young and middle aged people's migration to cities by industrialization and urbanization, and the movements of the aging people by family migration, and the movement of the aging themselves. Youngnam area's aging population and its distributional changes are as follows : 1. The number of Yongnam area's elderly population constantly increased from 245,504 in 1955, 312,245 in 1966, 378,567 in 1975, 486,403 in 1980, 535,805 in 1985, to 646,409 in 1990. In the urban areas such as Pusan, Daegu, etc, though the absolute number is increasing, the rate of elderly population is decreasing. But in counties, with the incrreasing absolute number the rate is also increasing. 2. the proportion of aging population to total aging population is increasing in metropolises and urban areas where total population is large, on the other side it is decreasing in rural areas. 3. Of the tatal aging population, 54.68% resides in rural areas, 45.32% in urban areas, especially 27.09% in metropolises, and 18.25% in small to medium cities. So the changes of regional distribution of the aging population is divided into urban and rural areas, and the regional difference is deepening. 4. The rate of aging population is low in metropolises and small to medium cities. Especially industrial cities such as Kumi, Pohang, Ulsan, etc, have the lowest rate, while traditional rural areas such as namhae(county), Hapchun, Kunwi, Euhsung, Andong, Chungdo, Koryun, Sungju, Kumrung, Sangju, Yechun, Younpoong, and coastal regions have the highest rate. The increase of the number of the aging population and the rate of elderly population causes many problems of the aging population and the regional concentration of aging population might hinder regional development which results from the shortage of labor force. So social porblems caused by the increase of elderly population and distributional difference and the elderly population itself are matters of concern.

AUTO CAD를 이용한 NC선반작업의 공구경로 검증을 위한 교육용 프로그램 개발

한영호,김동직 建國大學校 附設 産業技術硏究所 1993 논문집 Vol.18 No.-

Using AUTO LISP, an educational program for checking tool paths for NC turning operation has been developed under the widely used AUTO CAD environment. This program enables the NC class to give students chances for visual experience for tool path checking on a desk-top PC although the class can not afford to provide the highly expensive NC machines. The program is equipped with the ability to convert the CAD data to NC data even though it is not fully developed at the present state. A general purpose tool path checking program is expected possible for other machining jobs than the turning operation on the same basis of this study.

석회판의 강도증가에 관한 연구

이영석,이건직,박권필 順天大學校 1999 論文集 Vol.18 No.1

This study focused on the increase of lime plate strength by adding reinforced material into limestone and chemical reaction with carbon dioxide gas. Also we did experiment to find the optimum content of plaster as a binding component. Carbon fiber as reinforced material has disadvantages. It did not mixed well in the forming process and had low cohesion force with limestone. Content of glass fiber showed optimum at 1.0cm, 4.16 wt% in lime plate. The increase of strength in lime plate was ??, after reaction with CO₂at 70℃ for 6hr. When lime plate consists of 40wt% of plaster, 4.16 wt% of 1.0cm glass fiber, its strength was ??

店村邑의 都市的 性格

金永直 대구효성가톨릭대학교 1983 연구논문집 Vol.26 No.1

This study has focused on the urbanization of Jumchon town, which Iocates on the north-eastern part of Kyungbuk Province. Jumchon town has town has been steadly grown and become a regional center of North Kyungbuk Province. This area produces coal and limestone. The mine industries have brought non-basic industries such as commerce and transportation. For measuring the urbanization, two variables, population and land prices, have been adopted. Size and structure of population show a rapid urbanization. The change of the land price during 1970 to 1982 has jumped up 11 times and Jumchon-ri, Heungduk-ri, and Mojun-risurrounding the urban center become high land value areas, which prove urbanization process of the areas. Intra-structure of the city does not functionally divided, but land uses in a view of landscape can classify into: Commercial District between Jumchon station and No.34 national road; Residential District surrounding the commercial district; Industrial District apart from the urban center; and Non urban District. Economic activities of Jumchon on the analysis of occupational population fall functionally into mining city. In addition to this function of the town takes a role of commercial function and transportation. However, industrialization of the city still stays in poor stage, which causes slow growing of the city. Industrial sector is required in order to develope the urban center. Communication network of Jumchon by the analysis of the telephone calls is dominant over four towns and fifteen countries.

金永直 대구효성 가톨릭 대학교 1988 연구논문집 Vol.36 No.1

In this study, the change of the population distribution in Youngnam Area during recent 25 years(from 1960 to 1985) has been investigated. The major results are as follows; 1. By using the statistical methods such as the rate of urbanization, Coefficient of Variation(C.V.), Gini Coefficient, and the change of population density, the unbalancing degree between the urban and the rural areas was measured. The results were that the unbalancing degree appeared to be higher and higher. 2. Three distinct periodic characteristics were appeared in thepatterns of the population change. 1st period(1960~1970) ; that is the steady increasing period. 2nd period(1970~1980) ; that is the rapid increasing period. 3rd period(1980~1985) ; that is the stagnation period. 3. In view of time series, the population was remarkably decreased in the following periods and areas. 1) 1st period; in the inland-plain areas, and in the coast and the island areas. 2) 2nd period; in the mountain-side areas. 3) 3rd period; in the whole areas except for the urban and the new industrialized areas. 4. In the city and the county(Gun), the distribution pattern could be classified int o6 groups and in the town(Eup) and the village(Myun), it could be classified into 8 groups. Among those groups, the most remarkable one is that 15 cities among 17 cities in Youngnam area have been increasing consecutively durin g the whole kperiods, and that in the town(Eup) and village (Myun) about 70 percent of the population has kept on increasing during the whole periods. The migration from the rural area toward the urban area is till going on.

農村老人의 居住形態 : 嘉昌面과 華北面의 比較硏究

金永直 대구효성가톨릭 대학교 1983 연구논문집 Vol.27 No.1

Traditionally, the aged people in Korea lived with their son's family in a family system. However, such a living pattern has changed rapidly in accordance with industrialization and urbanization of a society. This study has investigated the living patterns of the aged in rural areas in the processes of urbanization. Two villages are chosen for the study: one is a suburban village(Kachang-Myun) which is located in the vicinity of Daegu, and the other is a remote village (Hwabug-Myun) which is in a distant place from the urban center. The major findings are: (1) The suburban village (Kachang-Myun) shows almost the same rate in number between extended families and nuclear families, but the rate in the remote village inclines to the extended families. It implies that the people in remote villages keep the traditional family system. (2) Of the actual living patterns, the percentage of the aged (live together) with son's family in Kachang-Myun is considerably higher than that (27.9%) of the aged who live separately, but we can not overlook the latter rate with is pretty high, while in Hwabug-Myun the former rate (81%) over-whelms the latter. (3) The statistics on the aged people's way of thinking about the living patterns indicates that 61 percent of the total aged people in Kachang-Myun want to live together, while in Hwabug-Myun still 79.3 percent aged people want to live with their son's family. (4) The fact that regional differences in the living patterns are remarkable seems to reveal that the degree to preserve the traditional culture in an area depends upon how ling the area is away form urban center So, whether an area is far or near from urban center may be a vital effect on the living patterns.

李相稷,呂基淑,李在亮,郭天錫,尙瑛錫 嶺南大學校附設 基礎科學硏究所 1988 基礎科學硏究 Vol.8 No.-

Cytochrome c oxidase (complex Ⅳ) was isolated from bovine heart mitochondrion. The spectra of isolated cytochrome c oxidase which was considered to be oxidized showed absorption bands at 598nm and 421nm in the oxidized form and at 604nm and 443nm in the reduced form. The activity of cytochrome c oxidase measured by the redox system of ferrocytochrome c-oxygen was not affected by NH₄OH and ethylenediamine. It was, however, found that 2-mercaptoethanol and potassium cyanide inhibited its reactivity respectively.
