정용희,류미숙,김영식,이우인,이희주,서환조 대한화학요법학회 2000 대한화학요법학회지 Vol.18 No.1

Eikenella corrodens is a slowly growing, facultative anaerobic gram-negative bacillus. It is a normal inhabitant of the human upper respiratory tract, and it is recognized as an infrequent cause of invasive disease. To date, a few cases of E. corrodens infection were noted from all other organ. We report herein two cases of E. corrodens infection. In one case E. corrodens was isolated in the lung abscess and in the other case it was in the appendiceal abscess. The patients were treated empirically with penicillin G. The results of the bacterial culture and sensitivity test were available with it. The patients were discharged 15 days later with marked improvement after treatment. Our report clearly demonstrates that E. corrodens can be the pathogen of lung abscess and intraabdominal abscess. We reviewed descriptions from the literature of infections caused by E. corrodens.

Consumerism, the defense by the public and government of consumer rights and interests as related to the products and services the consumer buys has come to occupy an important part of modern advertising. Consequently, advertising today is coming under closer public or consumer scrutiny than ever before. Unfortunately, through the past years, the performance of advertisers, advertising media and advertising agencies in the area of ethical conduct too frequently failed to reassure the public of its good intentions. Accordingly, the dysfunctional aspect of advertising has been the major target of extensive serious criticism, especially from the consumerists. In recent years, government rules and self-imposed regulations have been developed to exercise control over the whole medium of advertising. And these internal and external activities and restrictions serve to keep advertising basically truthful today. However, it should be stated that in spite of regulations, there are still countless advertisements that are untruthful and that do not meet industry and government standards. This study is an attempt to present in organized from an overview of consumerism in connection with the advertising ethics and government regulations in U.S.A., Japan and R.O.K..

김정례,박희진 울산대학교 2002 생활과학논문집 Vol.4 No.1

본 연구는 공동주택에 있어 옥외공간의 최초 계획의 중요성을 인식하고 계획단계에서 적극적으로 고려되어야할 옥외공간 요소 및 관련 변인을 규명하여 옥외공간 계획에 있어 경제적 낭비를 최소화하고 거주자의 만족도를 효과적으로 높일 수 있는 계획의 기초자료 제공을 목적으로 울산시 공동주택 거주자 382명을 대상으로 설문지를 이용하여 조사되었다. 연구결과 공동주택 거주자들의 옥외공간에 대한 전체적인 만족도는 평균이 2.82로 다소 불만족하는 것으로 나타났다. 공간별로는 도로공간, 옥외주차장, 지하주차장이 비교적 만족도가 높은 것으로 조사되었으며, 불만족한 공간으로는 주민들의 여가 및 취미생활과 관계된 휴게공간, 운동공간, 녹지공간이 조사되었다. 옥외공간 전체 만족도에 영향을 미치는 변인을 분석해 본 결과 녹지공간, 휴게공간, 운동공간의 만족도가 높을수록 전체 만족도가 높아짐을 예측할 수 있었다. 따라서 공동주택의 옥외공간 만족도를 가장 효과적으로 높이기 위해 이들 공간에 대한 신중한 계획이 필요할 것이다. The purposes of this study were to investigate the satisfaction of outdoor space and related variables in the recent built apartment in Ulsan and to provide the basic information for planning an outdoor space. The sample consisted of 382 residents living in four apartment complex and the data collected from questionnaires were analyzed statistically by using SPSS program. Overall degree of satisfaction on outdoor space was slightly low(M=2.82) and the outdoor spaces that showed relatively high satisfaction were road area and both indoor and outdoor parking areas. The areas related to residents' leisure and hobby such as rest area, exercise area, and green area were resulted in low satisfaction. It is predicted that the satisfaction of three areas(i.e., rest area, exercise area, green area) was likely to have significant effect on overall satisfaction of outdoor space. Therefore, it is recommended that apartment planners and developers should consider carefully to plan outdoor spaces especially rest, exercise, and green area to give a high satisfaction for the residents living in the apartment housing.

Ballet에 나타난 Character Dance에 관한 연구

송정희 경희대학교 체육과학연구소 1997 體育學論文集 Vol.25 No.-

Dance is the most human artistic term that develops very closely with the stream of history which if continuously changing. Dance, which takes a form of the most honest self-expression toward actual world, has been strongly survived through many difficulties and confusions of society and human circumstances as a reflection of the times. Particularly, folnk dance has been been transmitted today to prevail all over the world, and takes very important role in leading the cultural interchange for understanding every nation's peculiar characteristics and customs. It is because of that folk dance has developed while preserving a nation's unique culture and traditions in spite of her numerous social changes, and that also has largely contributed to the formation of culture and society through various traditional contents and forms of dance. And we can find the foundation of movement expression of folk dance existant in the form of ballet, and as the result it have given a considerable affect on movements and subject matters of ballet. In this thesis, I studied how character dance was utilized in the Ballet Daction on the basis of the above. Character Dance is considered to be utilized in the following three aspects; communicating expression, divertissment, creation. As the above, the dence study on folk dance brought not only diversity of movements as an expression style but also enlargement of subject matters, so that it would be a original source for choreographers who would intend to create dance. In reality, Historic Dance as well as Character Dance is studied deeply in foreign ballet schools. Therefore in Korea Character Dance should be introduced into curriculum in univcrsities and professional ballet corps. In order to develop ballet in Korea, I considered, we should have interest in Korean folk dance and the folk expressions should be developed and applied. Through this it is possible to settle the peculiar culture of national ballet. And then it is a good guiding principle to grope a desirous direction of ballet in the future, too.

Diet has been convinced to be an influential environmental factor of the development of coronary heart disease (CHD), though it is still on debate. The related dietary components include total fat, saturated fat, cholesterol, animal protein, fiber, and sugar. During last 50 years, most of the dietary studies concerning atherosclerosis and CHD have emphasized the role of fats. In recent years, however, the effect of sucrose on the development of CHD has received considerable attentions. In 1957 a significant positive association of sugar consumption with the coronary mortality was first pointed out by Yudkin in London. Since then, various epidemiologic and experimental studies have been carried out upon their relationships and have suggested the hyperlipidemic effect of sucrose as a possible etiologic factor of CHD In order to learn to what extent dietary sugar influences the development of CHD in man, the evidences were reviewed under three headings. First, interrelations between the intake of sucrose and the CHD incidence: second, experiments in man and in animals: finally, suggested possible metabolic mechanisms.
