Understanding the future level of car ownership is essential in order to formulate various transportation policies. Despite its importance, however, a revies of literature indicates that previous studies treated car ownership as a linear function of income, GNP, degree of urbanization and etc. more detaild and accurate models of car ownership should be possible if information on major variables determining car ownership can be gathered. In this paper, three approaches have been chosen to develop mathematical models to predict future increase in car ownership in Korea. The three methords developed are : income distribution methords ; multiple regression models ; forecasting curves.

In an attempt to revies the informations about genes involved in symbiotic nitrogen fixation, developmental processes in which host plant interact with microbe during nodule formation were introduced first. The structure, function and regulation of the genes discussed were mainly about microbial genes; those involved in the process of nodule formation (nod-genes) and of nitrogen fixation (nif-genes). Informations about the host genes involved in the symbiosis were discussed briefly.

Methods : We referred to PubMed by using searching words of acupuncture and the terms of pediatrics, such as child, children, adoiescence, baby, infant, juvenile. 22 journals with 23 paper were searched and reported. Results : 1. We found 23 articles in 22 journais, whose authors were in China, Japan, Germany, Russia, America, Brazil, etc. 2. Clinical trial was the method which these studies had used mostly the pattern of the rest were reviews, case reports of undetermined articles. 3. We analysed articles and found many articles of nocturnal enuresis, postoperative vomiting, etc. 4. The result of clinical studies represented the significant cure rate. 5. The acupuncture instruments on children's diseases were laser acupuncture, acupressure. and herbal skin sticking as well as body acupuncture,. Conclusion : Study of pediatric acupuncture was increasing and effective result was reported.

Carbon monoxide poisoning is one of the most serious health problems in Korea. In this review, the author made a intensive reference review on the causes of carbon monoxide poisoning, the patterns of carbon monoxide poisoning and the prospects of CO poisoning. Following findings were induced through the review. 1. Carbon monoxide poisoning is influenced by variable social factors than any other diseases or accidents and is more closely related with the economical and cultural parameters of the community. 2. The increase of risk in the populatlon is expected by National Energy Policy and the hazards of CO poisoning will rather be increasing as long as no radical control measure will be taken. 3. More practical control measure, including extensive public relation service, should be established to eradicate this serious health hazard in Korea.

감성 분석은 문장의 감성을 분석해 긍정 또는 부정으로 분류하는 작업을 의미한다. 문장에 담긴 감성을 파악해야 하기 때문에 문장 전체를 이해하는 것이 중요하다. 그러나 한 문장에 긍정과 부정의 이중 극성이 동존하는 문장은 감성 분석에 혼동이 생길 수 있다. 본 논문에서는 이와 같은 문제를 해결하기 위해 단어의 감성 점수 예측을 통해 감성 단어 등장 순서를 고려한 감성 분석 모델을 제안한다. 또한 최근 다양한 자연어 처리 분야에서 좋은 성능을 보이는 사전 학습 언어 모델을 활용한다. 실험 결과 감성 분석 정확도 90.81%로 기존 모델들에 비해 가장 좋은 성능을 보였다.
