Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.

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.

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.

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.

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.

윤영옥,조형호,조훈,김세광,김영직 대한금속재료학회 2005 대한금속·재료학회지 Vol.43 No.3

The refining efficiency of high-purity Cu was investigated prepared by zone refining, with respect to travel rate, distribution coefficient, number of pass and zone length. Especially, to investigate refining efficiency with respect to zone length, experimental and computer simulation results were compared. The composition of the refined high-purity Cu was analyzed by GDOS (Glow Discharge Optical Spectroscopy) and GDMS (Glow Discharge Mass Spectrometer). The composition profiles of each segment at the given condition were compared with the results of micro hardness profiles. The results showed that the refining efficiency was inversely proportional to the travel rate, while it was proportional to the number of pass. The travel rate was more effective than the number of pass to enhance the refining efficiency in zone refining process. Impurities whose distribution coefficients are below 0.5 were removed efficiently. The effectively refined region increased with decreasing the zone length from 45 mm to 30 mm. Especially, the element S, which is known to be hardly removed by zone refining, could be removed to a level of under 0.1 ppm over the 60% region at 1 mm/min. (Received July 22, 2004)

In_(2-x) Ga_x S_3 박막 생장과 Composition에 따른 Energy Gap의 변화

郭泳稙,金根默 수원대학교 산업기술연구소 1986 산업기술연구소논문집 Vol.1 No.-

In_(2-x)Ga_xS_3 thin films that varied in composition from x=0.0 to 1.2 were grown on thoroughly cleaned glass substrates by the spray pyrolysis method. When the substrate temperature was maintained at 350℃, β·In_2S_3 polycrystalline thin film was grown on the slide glass in case of x=0.0, and In_(2_x)Ga_xS_3 thin films in the amorphous state for composition above x=0.6. The x-ray diffraction peak intensity for the (220) plane of the β·In_2S_3 polycrystalline thin films decreased with increasing x up to 0.6. The energy gap of In_(2_x)Ga_xS_3 thin film for the β·In_2S_3(x=0.0) polycrystalline structure was found to be 2.20 eV at room temperature. The energy gap was decreased with increasing the composition in the range x=0.0 to 0.6 with a polycrystalline structure; there was an anomality at x=0.6; and then it was abruptly increased with increasing x composition with an amorphous structure.
