본 논문에서는 병렬 유전 알고리즘을 이용한 발전기 기동정지계획을 제안한다. 최소 기동 및 정지 시간 등과 같은 다양한 발전기의 제약조건을 만족시키면서 발전기 기동정지계획을 수립하는 문제는 비선형적이며 많은 국부해가 존재하므로 최적해를 탐색하는데 많은 시간이 소요된다. 이러한 문제점을 해결하기 위해 16개 의 프로세서를 가진 병렬 시스템과 이를 이용한 병렬 유전 알고리즘을 제안하였으며, 제안한 방법의 효용성을 검토하기위해 10기 및 26기의 전력계통에 적용하여 시율레이션을 시행하였다. 시율레이션 결과 기존의 방법에 비해 탐색속도를 개선하였고 우수한 해를 구할 수 있었다.

The purpose of this study was to investigate the functional adaptation of the tongue, the hyoid bone, the digastric muscle and the upper airway and the variables predicting postoperative stability following orthonathic surgery in patients with mandibular prognathism. 18 patients were selected(8 men and 10 women) for this study, who had received orthognathic surgery. Their lateral cephalograms, those were taken preoperatively, immediate postoperatively and over 6 months follow-up, were traced and analysed. The results were as follows : 1. The downward displacement of the hyoid bone and extended head posture were recognized, right after operation. Statistically significant correlations were found between the changes of the mandibular position and the digastric muscle and the change of head posture during operation. 2. The tongue was displaced downward following the hyoid displacement postoperatively. Statistically significant correlations were found between the change of the mandibular position and the change of the distance of the tongue and hard palate, and between the change of head posture and the changes of the upper airway sizes, the digastric muscle and the hyoid position during over 6 month's follow-up. 3. The change of the distance of the tongue and hard palate was the most significant factor for prognosis during over 6 month's follow-up. 4. There were no variables before operation to predict the postoperative stability and the constriction of the upper airway.

휴전선 인접 마을의 새마을운동 사례를 통해 본 1970년대 한국 농촌사회 정치·경제적 변화 : 강원도 철원군 사곡2리와 군탄1리를 중심으로

이 논문은 1970년대 권위주의 유신체제 하에서 농촌근대화를 목적으로 추진되었던 새마을운동이 한국 농촌사회에 어떠한 정치적·경제적 변화를 초래하였는지 살펴보는 것을 목적으로 한다. 실증적인연구제시를 위해 강원도 철원군 근남면 사곡2리와 갈말면 군탄1리 두 마을의 새마을운동을 사례로 분석하였다. 이 사례연구는 한수이남에 집중되어 있던 기존 새마을운동 연구의 공간적 범위를 휴전선인접지역까지 확장시켰다. 1970년대 당시 두 마을 새마을지도자들과의 인터뷰 자료와 현재 마을회관에 남아 있는 새마을운동사업 기록을 토대로 마을간 사업추진 방식과 두 마을 주민들의 참여태도, 사업성과 둥을 분석하였다. 철원군 근남면 사곡2리와 갈말면 군탄1리의 새마을운동 전개양상은 마을의 입지조건 및 마을 구성원의 차이에 따라 상이한 결과로 나타났다. 사례연구의 케이스가 협소하긴 하지만, 이 연구를 통해서 새마을운동이 직 ·간접적으로 농촌사회에 가져온 변화를 찾을 수 있었다. 새마을운동은 마을 단위로 진행되었기 때문에 동일 지역에서도 마을구성의 상이한 조건적 차이로 인해 새마을운동의 결과도 다르게 나타났다. The objective of this thesis is to see political and economic changes in Korean rural society in 1970s when Saemaul Undong(Movement) was launched by authoritarian government for the modernization in an agricultural district. This paper focuses on Saemaul Undong in two villages of Cheorwon, Kangwon Province or Sagok2-ri and Cuntanl-ri in order to provide actual evidence. Based on the interviews of two towns' then Saemaul Leaders and the information on Saemaul Undong of those areas during the 1970s, this research analyzes people's attitudes, the way of the Movement and the achievement of the Movement. In addition, this paper emphasizes on some changes in political and economic areas of the two villages for about 8 years, comparing to before and after the movement being implemented. They have similarities as well as differences in the stages of Saemaul Undong. firstly, it led the dwellers to actvely participate in the process. Secondly, the residents could express their opinion to the government through the town meefngs. Thirdly, newly-elected leaders, called Saemaul Undong leaders were main actors who are at the center of the course. Although they took the helm just within the Saemaul Undong project, their capacities resulted in various consequences of the Movement under the autonomy of the town unit. Apart from other changes, it altered the appearances of the rural communities. It came to build new roads, convert old houses to modernized ones. It is difficult to say that Saemaul Undong has drawn the actual increase in the economic incomes. However, development in the repairing facilities in it played a key role in going up in the crop productivity, Therefore, it is fair to say that Saemaul Undong had a positive effect on the agricultural economy to some extent.

This study was performed to collection basic data to identify the measurement of dust exposure in industrial environments. The major objectives were to establish the quality control and standardization of dust sampling and analytical methods. First, comparative tests on the constant between glass fiber filter and PVC filter were performed. Weight of glass fiber filters and PVC filters were measured in variable conditions. -the change of filter type(glass fiber & PVC filter), dry time(24hr, 48hr, 72hr, 96hr), constant method(using dry oven)-. Weight variation of each filter was analyzed by a balance in each condition and the relationship between each constant measurement data were analyzed statistically by SAS package program. The results were as follows: 1. The weight variation of glass fiber filters reduced in proportion to constant time changes and relative standard deviation were less than 2%. It was significantly difference between decrease of glass fiber filter and increase of dry time(P<0.05). 2. The weight variation of PVC filter not reduced in proportion to constant time changes and relative standard deviation was less than 4%. It was not significantly difference between decrease of glass fiber filter and increase of dry time(P>0.05). 3. The weight variation of glass fiber filters reduced in proportion to constant method changes by using dry oven and relative standard deviation was less than 2%. It was significantly difference between decrease of glass fiber filter and increase of dry time(P<0.05). 4. The weight variation of PVC filters not reduced in proportion to constant method changes by using dry oven(50℃, 70℃)and relative standard deviation was less than each 2%. It was significantly difference between decrease of glass fiber filter and increase of dry time(P>0.05). Finally, it is necessary to study the applicability of sampling material information for dust exposure measurement in industrial environment.

The purpose of the study was to discuss korean, linguistics, geography, and history by dividing it into two villages in Jincheon-eup and six villages out of 304 natural villages, and to think that place names serve as the starting point for finding language, history, and roots of jincheon-gun. The name of jincheon-gun has been changed to manno-gun→geummulno-gun→heukyang-gun→jinju→sangsan→jincheon. The name of the current jincheon began in 1413(the 13th year of King Taejong's reign) and has been 610 years to date. Place names are products of language and culture. Over the years, there must be validity and rationality in the naming rules and principles of change in korean. In the name of the natural village in jincheon-gun, it was confirmed that it was important to change and use chinese characters, but that our language and culture should be clearly recognized and utilized. I will make some suggestions to inherit and develop the natural village name of jincheon-gun. First, efforts should be made to revive jincheon's language through place names. Second, the origin of the name of the natural village lays the foundation for finding history and culture. Third, experts, members of the jincheon local history association, and jincheon cultural center should use it for education to students and local residents. Fourth, it should be applied to regional development using place names for the first time in the country. Fifth, various contents should be made with the name of a natural village. Sixth, jincheon-gun, which is good to live in, should inspire affection, pride, and pride by naming a natural village.

Objectives : This study aimed to determine the general predictive factors of change in drinking behavior and to provide materials for preventing drinking problems during early adulthood through examining genetic and psychosocial factors affecting the change of drinldng behavior in college students. Methods : The subjects were 101 male college students, apart of 534 students who had completed the previous study in 2000. In the present study as a 6-years follow up, we reassessed the drinking pattem and psychosocial variables and compared the results with previous data of the same subjects. To identify factors affecting the current drinking pattem, we used stepwise multiple regession and logistic regression analysis. Results : D allele (ALDH2) was found to reduce the degree of drinking and suppress problematic drinking, and C allele (TPH) had a suppression effect on problematic drinking. Drinking motive had a direct effect on the degree of drinking and Pro-blematic drinking. Negative cognitive expectancy had a direct effect on problematic drinking. Conelusion : Authors found some factors affecting the change of alcohol drinking behavior in college students and confirmed that there were hierarchies of significance among these factors. These may be applicable as variables for predicting drinking behavior in early adulthood.

조인수,장경옥,박정식 한국정신지체아교육학회 2003 지적장애연구 Vol.5 No.-

21세기의 교육 사회의 변화에 발맞추어 특수교육에 있어서도 질적ㆍ양적으로 빠르게 발전하고 있다. 특히 지난 30여년간 양적으로 팽창되어온 특수학급은 특수교육 인구와 특수교육 기회의 저변확대의 도움과 영향에 커다란 의미를 지닌다. 하지만 특수학급 교육에서 양적인 팽창 못지 않게 질적인 변화를 도모하기 위해서는 일선 교육현장의 실태파악 및 문제점 도출에 힘써야 할 것이다. 이 연구는 중학교 특수학급에 자녀를 입급 시킨 학부모의 특수학급 교육여건, 교육내용, 교육운영에 대한 요구를 조사하여 분석함으로써 특수학급 교육의 문제점에 대한 개선방안을 모색하여, 보다 더 효율적인 특수학급 교육의 방안을 제시하고자 한다. The purpose of this study was to examine what parents required from secondary school special class education, in an effort to seek ways to resolve the problems with special class education and to discuss how it could be conducted better. Specifically, it's meant to find out parent needs for secondary school special class, educational condition, teaching contents and educational system. The following findings were acquired: First, regarding parent need for special classroom environment, the parents investigated found it necessary to prepare a separate space for individual guidance. Second, concerning what to teach, they demanded that students be assisted to be able to support themselves. Third, the parents considered it most necessary to prepare a sort of learning assistance room, which indicated that they called for integrated education environment. There are some suggestions: First, the subjects in this study were confined to the parents from south Gyeongsang province, but future research efforts need to examine a wide range of subjects nationwide. To meet the requirements of parents and students, sustained research is required. Second, the middle school special classes were investigated, but it's necessary to make studies of diverse approaches to find out what parents from high school needs and whether their needs are different according to the type of disability. Third, well-planned parent education should be provided to have parents pay more attention to physically different students and change their mind-set about them.
