This study analyzed the size and influence factors of annual average health expenditure according to job type. Using data from the Korea Health Panel (2012), the final analysis was conducted on adults aged 20 years or older, excluding the missing data. Data analysis was done by logistic regression analysis to analyze the factors affecting medical expenditure. As a result of the study, Model 1 showed higher expenditure on medical expenses by skilled workers in agriculture and forestry fishery than those in simple labor. Model 2 was analyzed as having a positive effect on the increase of medical expenditure by the simple worker in the sales of the occupation, statistically significant by sex, marriage, income level and chronic disease. Therefore, it would be necessary to establish social security and health care & welfare policies, in order to grasp the disease with a high frequency rate according to occupation status and activate the physical examination and preventive actions.

The major objectives of this study are to identify the key organizational factors that facilitate and/or inhibit the IS outsourcing in Korean hospitals, and to analyze the differences between adopter & non-adopters and successful ones and not-successful ones. In order to achieve the research objectives, we derived comprehensive lists of potential facilitators and inhibitors from the past research, and conducted a field survey on 135 hospitals in metropolitan area. The analysis results suggest that organizational, financial and strategic factors are the most important facilitators, while organizational, psychological, vendor-related and environmental factors are the most important inhibitors. In addition, it was found that factors differentiating adopters and non-adopters are organizational factor(facilitator) and environmental factor(inhibitor) while strategic factor is a differentiating one between successful hospitals and unsuccessful ones.

정보기술의 발전과 더불어 경쟁적인 비즈니스 환경에서 살아남기 위해서 소비자가 원하는 정보시스템을 일정 내에 그리고 한정된 예산 내에서 개발해야 하지만 소프트웨어 개발생산성의 정체로, 소프트웨어 재사용의 필요성이 높아지고 있다. 이에 S/W 재사용이 성공적으로 조직에 정착하기 위한 비 기술적인 요인들을 살펴봄으로써 소프트웨어 개발 생산성과 품질의 향상에 기여하고자 한다. 본 연구에서는 개인적요인, 조직 및 관리적 요인, 환경적 요인 등의 비기술적 요인이 소프트웨어 재사용 비율에 미치는 영향을 일차적으로 분석하고, 소프트웨어 재사용 효과와의 관계를 파악하였다. 연구결과 경험지식과 조직문화가 재사용율에 미치는 영향이 큰 것으로 나타났으며, 일부 요소들은 영향의 정도가 약한 것으로 나타났다. 향후 연구에서 보다 체계적인 연구모형에 의한 심층 분석 연구가 필요할 것이다.

국내의 도로용량편람에 근거한 좌회전 신호의 선택기준은 4방향 접근로 각각의 방향별 교통량, 좌회전 전용차로의 유무, 차로수 등의 수많은 요인들을 통해 결정된다. 이 요인들은 각각의 특성에 따라 좌회전 신호의 선택기준에 미치는 영향력이 다르며 그 영향력의 크기에 따라 변수를 결정해야 한다. 그러나 국내에서 사용되고 있는 대부분의 좌회전 신호의 선택기준은 이러한 검토 없이 해당도로의 한 방향 좌회전 교통량과 이와 마주보며 진행하는 직진 교통량, 차로수만을 기준으로 결정되고 있다. 따라서 본 연구는 국내 도로용량편람의 알고리즘을 이용하여 좌회전 신호의 선택기준에 영향을 주는 주요 요인을 밝히고, 이 결과를 이용하여 임계좌회전 교통량 (비 보호좌회전 신호로 신호교차로의 운영효율을 극대화 할 수 있는 최대 좌회전 교통량)을 제시함으로서 비 보호 좌회전 준거를 설정하고자 하였다. 본 연구에 의한 결과는 다음과 같다. 첫째, 좌회전 신호의 선택기준에 영향을 주는 주요요인은 해당도로의 좌회전 교통량, 대향직진 교통량, 차로수, 교차도로의 교통량과 차로수이며, 이 요인들 중에서 해당도로의 차로수가 좌회전 신호의 선택기준에 가장 큰 영향을 미치는 것으로 분석되었다. 그러나, 비 보호좌회전은 일반적으로 2차로에서 운영되므로 보편적인 상황에서의 비 보호좌회전 신호의 선택기준은 해당도로의 좌회전 교통량. 대향직진 교통량 및 교차도로의 교통량에 좌우된다. 둘째, 대향직진 교통량이 커질수록 임계좌회전 교통량은 감소하는 것으로 분석되었다. 셋째. 교차도로의 교통량이 커질수록 임계좌회전 교통량은 감소하는 것으로 분석되었다.

Drinking Problems among college students have been increasing and being severe social problems. When it is compared with other areas, the research about drinking problems of college students are rare. This study was to examine psychosocial factors influencing on problem drinking among college students. The sample size of this study was 414, which made it possible to do statistical inference. AUDIT was applicated to measure the drinking problems in college student. As statistical method, $X^2$-test, t-test, hierarchial multiple regression analysis were used. The main finding provided that drinking problem of college students was more severe than adult one. Especially binge drinking pattern was remarkable. Male student had many alcohol problems than female students. This study also revealed gender, religious activity, first drinking age, sensation -seeking, drinking motivation, parents' drinking problem, schoolwork record, peer influence had significant direct impact in problem drinking of college students. Based on the results of this study, the author suggested some practical implication and preventive program based on the results and added further study tasks.

This research outlined the factors influencing the business management success via analyzing a survey of business principles. The research process has been tested in comparison of both financial factors, which come out of objective data and non-financial factors so relevantly prioritized by combining these factors. In order to specify the factors, a check-list and analyzed essential features of category have done with interviews and surveys. As consequently proceeding, the authors could deduce that non-financial but analytic factors such as business doable, technician workability, compensation and benefits etc. play major roles in construction sector. The outcomes consider a construction business as fundamental human labor job as opposed to a manufacture business. On reasoning necessarily more objective research works to be done as developing this research's outcome, it is meaningful in suggesting the pivotal factors influencing the construction business management. Therefore, this research is expected to guide the direction to induce the improvement of business management to be done by further exemplary researches.

The Risks in undertaking a construction project comes from many sources and often involves many participants in the project. This study has identified various kinds of risks, assessed the risk factors quantitatively and suggested risk management method for response pertinent in Design Build(Turn Key)type of projects in Korean context. A questionnaire was designed comprising of 145 possible risks in all types of construction projects. The population from owner, consultant and contractor groups was asked to indicate the risks applicable in DB projects. 25 numbers of critical risks in DB projects were identified and further analyzed for reveling inherent relationship between them through factor analysis. Factor analysis revealed 8 risk factors in DB projects. Construction site related, contract related and design related risk factor consisted about 72% of total risk weight. It has been found out about 6%, while considering the mutual dependency, it is about 10% of total cost of DB project. Therefore, It is suggested that 6% to 10% of construction amount as contingency has to be made provision for risk responses in the DB projects.

The maintenance expenses of public rental housing have drastically been increased as facilities become obsolete. As an effective means of managing such a situation, accurate estimating of maintenance expenses and securing financial resources are crucially important. It, therefore, is necessary to analyze major factors affecting on maintenance expenses of public rental housing's facilities, and develop an effective instrument to estimate them. On the other hand, the U.S.A, where approximately 60 percent of public rental housing's operating costs are supported by the state, has already developed an effective tool to forecast operating costs based on several years' actual data. As a result, public rental housing has been operating with a reasonable level. However, there have been no remarkable researches and studies in this field in Korea. In this context, this study attempts to examine principal determinants of maintenance expenses of public rental housing's facilities, and their influence based on the latest five years' actual operating costs. This study may contribute to develop an objective and precise tool to forecast maintenance expenses of public rental housing.

본 연구는 연변 지역 조선족 여자 대학생을 대상으로 의복태도에 따른 의복구매동기를 조사함으로써 소비자의 심리적 특성을 밝히는데 그 목적이 있다. 2002년 5월에서 6월 사이에 300부의 설문지가 중국 연변 지역의 여자 대학생에게 배부되어 248부의 설문지가 최종적으로 분석에 사용되었다. 설문지는 5점 척도를 사용하였고, 통계처리는 SAS PC 프로그램을 이용하여 빈도, 요인분석, t-test를 하였다. 연구 결과를 요약하면 다음과 같다. 여자 대학생의 의복태도는 유행성, 유명상표지향성, 심미성, 정숙성의 네 요인으로 분류되었다. 각 요인 별로 요인의 평균값이 높은 집단과 낮은 집단으로 분류하여 의복태도에 따른 의복구매동기를 조사한 결과, 유행성${\cdot}$유명상표지향성${\cdot}$심미성${\cdot}$정숙성 네 요인 모두 각 요인 별로 평균값이 높은 집단과 낮은 두 집단 간에 유의한 차이를 나타내었다. 유행성요인에 높은 평균점수를 갖는 집단은 낮은 집단에 비해 멋진 외모나 새로운 유행을 추구하기 위해 의복을 구입하는 동기가 높았고, 미적요인에 높은 평균점수를 갖는 집단은 낮은 집단에 비해 실용적 이유보다는 사회적 모임이나 기분의 변화를 위하여 의복의 구매동기를 가졌다. 이러한 결과를 통하여 의복태도는 중국조선족소비자의 경우에도 의복구매행동을 예측하는 좋은 변수가 될 수 있으며 시장세분화를 위한 유용한 기준이 될 수 있음을 확인하였다.
