The main purposes of the study were to analyze: 1) the effects of family environment, school environment, I.Q., academic performance (grades in both middle school and high school) and sex on self-esteem and the college educational aspiration of the high school students ; and 2) the effects of self-esteem on their college education aspiration. In this study it was assumed that family environment, school environment, I.Q., academic performance and sex were treated as the independent variables, self-esteem as the intervening variable and college educational aspiration as the dependent variable. Family environment variable includes the socioeconomic star us of parents and socialization pattern of parents (affection-rejection, self-control-others -control, and achievement--non-achievement). School environment variables consider the influence of teachers, peer influence and school curriculum. Data for the study were collected through the use of self-administered questionnaires from a sample of 715 high school students in Pusan, Korra in August and September, 1984. The results of the study are summarized as follows : (1) There was no effect of self-esteem on the college educational aspiration of high school students. (2) Among the independent variables the school curriculum was the most important variable in determining the aspiration of college education. (3) Grade in the middle school, sex and socialization pattern of parents (achievement-non-achievement dimension) were also important variables in determining the aspiration of college education.

세계경제질서의 변화

Since the end of World War Ⅱ, the world was conspicuously divided into two poles, capitalism and socialism, and world order was maintained based on the structure of confrontation in terms of ideology and political system. The world is undergoing liberalization and globalization spurred by the breakdown of the Cold War order and is community due, in particular, to the advances of telecommunication technology. This is what we call the transition from the dual structure to a single-pole structure, or the emergence of globalism. Globalism leads to transition from the structure of political and military confrontation to the structure of economic confrontation, which inevitably generates nationalism and regionalism. As the national integration based on ideology and political system becomes out of the question, nationalism is rising again as the basis for national integration. However, under globalism, no country can maintain a closed economic system completely cut off from outside, and hence, no country can help being exposed to fierce economic war. In this new current of the times, supernational capital is becoming rapidly accumulated and the competition of capital is becoming ever more fierce. Overheated economic competition causes rapid expansion of production capacity, which requires expansion of market size and strengthening of market control. This requirement in turn spurs regionalism.

The power semiconductor switching devices(PSSD) continuously developed, Power Electronic Technology using PSSD is gradually extended. The high frequency inverter to generate the large power high frequency subject to power electronic technology pursuit various application. Also, in emboss with environmental destruction problem cause the atmosphere and the water pollution to growth of the commercial society, the research in favor of cleansing environmental a pollutant actively proceed. Cause of having a strong oxygenization in the physical world, the ozone has sterillization effect predominantly against virus, bacteria, etc and has application in decolorization, deodorization, food storage and air cleansing and has a merit that does not cause the secondary pollution by being restored to oxygen lastly. Therefore, This project describe study on the ozone generation power supply using the high frequency electric field method and the lamp type ozone generator using photochemistry, one of method of generate ozone.

This paper is focused on evaluation of daylight reflecting performance from the adjacent building for improvement of poor environment conditions in a metropolitan area. The numerical model developed can be used for evaluation of daylight reflecting performance. As a result comparison of our simulation programs and commercial softwares, it was verified that there was no difference between two results. In this study, the sensitivity analysis of environmental performance factors of daylight reflecting from the adjacent building were examined, analysed and presented as a solution method for improvement of building environments. The results were proved to be an effective control methods for improvement of building environment, especially in a metropolitan area.

Tracheobronchopathia osteoplastica is a rare disorder of unknown cause characterized by the projection of numerous bony or cartilaginous submucosal nodules into the tracheobronchial lumen with sparing of the posterior membranous portion of tracheobronchial tree. In the past, most of the cases were diagnosed as secondary finding at autopsy. Nowaday, the key component of the evaluation is flexible fiberoptic laryngoscopy and bronchoscopy, which typically demonstrates irregular spicules of subrnucosal bone and cartilage projecting into the tracheobronchial lumen and causing various degrees of airway obstruction. A 45 years old man was visited Sunchon St. Carollo hospital due to discomfort on throat. We saw several nodules just below vocal cord via laryngoscope. The computed tomography revealed multiple small calcified nqdules on trachea and both main bronchi. Pathologic finding of bronchoscopic biopsy showed abnormal proliferation of bony and cartilagious nodules in the tracheal submucosa. These fingdings were consistent with tracheobronchopathia osteoplastica. We report here on a case of tracheobronchopathia osteoplastica with review of literature.

Rifampicin에 의한 것으로 추정되는 위막성 대장염1예

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.

In this paper the authors tried to explicate from applying n-person game theory that the result of simple majority rule depends on the financing methods of the respective project, the nature of benefits from the project, and on the extent of the allowance of side payments. We could particularly verify that if side payments were allowed, then it would be possible to eliminate or reduce severe social wastes from simple majority rule.

The secondary school equalization policy in Korea was initially adopted to curb excessive out-of-school studies of the junior and senior high school students. It failed to accomplish its goal in this regard, however Rather, that policy exacerbated the excessiveness of out-of-school studies. We explain why in this paper.

Homologous Alkalophilic and Acidophilic l-Arabinose Isomerases Reveal Region-Specific Contributions to the pH Dependence of Activity and Stability

Lee, Sang-Jae,Lee, Sang Jun,Lee, Yong-Jik,Kim, Seong-Bo,Kim, Sung-Kun,Lee, Dong-Woo American Society for Microbiology 2012 Applied and environmental microbiology Vol.78 No.24

<B>ABSTRACT</B><P>To study the pH dependence ofl-arabinose isomerase (AI) activity and stability, we compared homologous AIs with their chimeras. This study demonstrated that an ionizable amino acid near the catalytic site determines the optimal pH (pHopt) for activity, whereas the N-terminal surface R residues play an important role in determining the pHoptfor stability.</P>
