This research wished to risk type and examine closely driver special quality and relation of traffic accidents by occurrence type of traffic accidents and traffic accidents seriousness examine closely relation with Severity. Fractionate traffic accidents type by eight, and driver's special quality for risk group's classification did to distinction of sex, vehicle type, age etc. analyzed relation with injury degree adding belt used putting on availability for security the objectivity with wave. Used log-Linear model and Logit model for analysis of category data. A head-on collision and overtaking accident, right-turn accident are high injury or death accident and possibility to associate in relation with accident type and seriousness degree. In risk group analysis The age less than 20 years in motor-cycle driver, taxi driver in 41 years to 50 years old are very dangerous. The woman also was construed to the more risk group than man from when related to car, mini-bus, goods vehicle etc. Therefore, traffic safety education and Enforcement for risk group that way that can reduce accident that produce to reduce a loss of lives at traffic accidents appearance a head-on collision and overtaking accidents, right-turn accidents should be studied and as traffic accidents weakness class may have to be solidified.

The aim of this paper is to examine the buffering effect of family cohesion in the relationship between depression and suicidal risk among adolescents, adults, and the elderly. To achieve the research aim, surveys were conducted in 10 cities across the country for 399 adolescents, 473 adults, and 370 elderly from May to August 2010. Major findings of the data analysis are as follows. First, while, in the relationship between depression and suicidal risk, the elderly were the highest, followed by adolescents and adults in descending order, in family cohesion, adults were the highest, followed by the elderly and adolescents. Second, the analysis of the buffering effect of family cohesion in the relationship between depression and suicidal risk showed that it was significant only for adolescents and adults, which means that for those two groups family cohesion alleviates the effects of depression on suicidal risk, demonstrating the necessity of strengthening family cohesion to reduce suicides among the two groups of people. But, for the elderly for whom family relationship is more important than any other age group, the buffering effect of family cohesion in the relationship between depression and suicidal risk was not proved. The interpretation of this phenomenon is given in the part of the paper where the characteristics of the suicide of the old age group is discussed.

최근 조직간정보시스템의 연구는 조직간 전략적 협력을 형성함에 있어서 발생될 수 있는 잠재적 갈등의 위험 인지에 초점을 두고 있다. 기존 연구 대부분은 조직간의 위험발생에 있어서 경제적 관점의 위험에만 초점을 맞추고 있다. 이는 조직간 기술적 호환과 관련된 기술적 문제, 조직상호간의 활동, 서로 다른 문화ㆍ전략 차이간의 조정에 요구되는 사회정책적 문제는 고려하지 않고 있어서 조직간의 합리적이며 경제적인 협력적 동맹관계를 논의하는데는 충분치 않다. 따라서 조직간 협력적인 동맹관계를 다루기 위해서는 기존의 경제적 관점에 기술적 관점, 사회정책적 관점을 추가한 세가지 측면에 대한 고려가 필요하다. 본 연구에서는 먼저 조직간 정보시스템의 개념적 특성을 살펴보고, 조직간의 상호의존성, 구조적 특성, 기술, 조정매카니즘 요소등에 의해 정보자원공유, 가치사슬망, 네트웍 형태의 세 가지 유형으로 구분하여 각 유형별에 대한 경제적, 기술적, 사회정책적 관점의 위험을 분석하고 위험을 최소화하기 위한 관리방안을 제시하고자 한다.

논문은 항만 위험관리의 한 분야로 항로를 계획하거나 기존 항로를 검증하는데 필요한 조선자의 조종상의 곤란한 정도를 다루기 위한 것이다. 이 논문은 한국해양연수원이 보유하고 있는 실시간 풀미션 선박조종 시뮬레이터를 이용하여 부산 북항의 방파제 통과시에 나타나는 조선자의 주관적 평가와 조선자가 시행한 조종 위험도에 대한 상관관계를 비교하였으며 조선자의 심리적 부담감이 실제 조선에 어떻게 나타나는가를 중점적으로 다르고 있다. 이 논문의 결론은 두 가지로 말할 수 있는데 하냐는 조종위험도와 주관적 평가 사이에는 상관관계가 있어 조종위험도가 크면 주관적 평가도 같이 증가함을 알 수 있고 다른 하나는 충분히 'tideway'를 주면 통과할 수 있는데도 불구하고 시각적으로 보이는 여유 공간에 제한을 받아 통과할 정도의 'tideway'를 줄 수 없는 점이다. 이를 보면 시각적으로 보이는 모습이 항로 설계에 중요한 부분이 됨을 알 수 있다.

The purpose of this study is to analyze service quality factors that consumers perceive during their purchasing product on Internet Shopping Mall. The study defines the characteristic quality dimensions of Internet Shopping Mall by adding three dimensions consisting of convenience, security and entertainment to PZB's SERVQUAL scale. Consumers' purchase process on Internet Shopping Mall is examined by finding the relation between their perceived risk factor and repurchase intention. The study results show that consumers' higher appraisal degree on service quality means their higher repurchase intentions, their lower perceived risks degree. The repurchase intentions and the perceived risks degree have negative correlation. The more consumers have experienced buying on Internet Shopping Mall, the higher consumer assess service quality, they have higher repurchase intention and lower perceived risk. The most basic contribution is that new service quality dimensions, which is able to clarify service quality on Cyber Mall, is identified with the established PZB(I988; 1991)'s SERVQUAL dimensions.

This study intents to discover the variables impacting consumer's purchase intention through the electronic commerce based on concerning the Flow experience in an environment using computer as a medium and furthermore it is based on a premise that its influence on purchase intention can vary. The following are the synopsis and findings of our analysis. First, analyzing the awareness of perceived risk and level of involvement depending on the level of skill and challenge, which are conceptual structural dimensions, we found that, the higher the level of skill, the lower the awareness of perceived risk, and for challenge, the level of involvement increased. Second, since the sense of perceived risk, level of involvement and purchase intention had a negative influence and were found to have cognizable relationship with one another statistically, this has negative impact on the level of involvement depending on the level of sense of perceived risk in electronic commerce. Third, analyzing the purchase intention depending on the level of involvement, we found out it has a highly positive influence on purchase intention. Furthermore, the level of involvement and purchase intention were found to be closely related to each other.

This research examined relationships between Scientifically Estimated Environmental Risks (SEERs) of floods, hurricanes and hazardous material releases, and household characteristics. This research showed that there were no statistically significant relationships between most of the demographic characteristics (age, household size, tenure at the present home) and SEERs of the two natural hazards (a flood and a hurricane). These results support Drabek's findings (1986) that people tend to underestimate or ignore natural hazards in selecting their residence regardless of age, household size, and house tenure. Educational attainment and yearly household income were positively correlated with hurricane risk, but not with flood risk. By contrast, SEER of hazardous materials was correlated with all demographic characteristics mentioned above. This result may show that those who are relatively poorer and have lower educational level tend to be limited to living in communities more vulnerable to human-made risk.

Dam risk analysis requires a systematic process to ensure that hydrologic variables (e.g. precipitation, discharge and water surface level) contribute to each other. However, the existing dam risk approach showed a limitation in assessing the interdependencies across the variables. This study aimed to develop Bayesian network based dam risk analysis model to better characterize the interdependencies. It was found that the proposed model provided advantages which would enable to better identify and understand the interdependencies and uncertainties over dam risk analysis. The proposed model also provided a scenario-based risk evaluation framework which is a function of the failure probability and the consequence. This tool would give dam manager a framework for prioritizing risks more effectively.

본 연구는 우리나라 상장기업중 금융 보험업을 제외하고 비교적 상장기업수가 많은 9개 산업에서 임의로 선정한 180개 표본기업을 분석대상으로 하였다. 1989년 1월부터 1996년 12월까지를 분석대상기간으로 설정하여 베타계수 예측능력을 향상시키기 위한 회계위험변수모형의 예측능력을 평가하고 위험수준별 예측능력에 차이가 있는지도 분석하였다. 아울러 베타계수 추정시 사용된 수익률 측정간격에 빠른 베타계수의 안정성과 회계위험변수모형의 예측능력을 분식하였다. 본 연구의 중요한 결과를 요약하면 다음과 같다. 첫째, 포트폴리오를 구성한 경우 수익률 측정기간에 관계없이 일관되게 예측오차가 유의적으로 적게 나타나 회계위험변수모형의 베타계수 예측능력이 우수하였으며 베타계수예측에 회계 변수의 유용성이 확인되었다. 둘째, 위험수준에 따른 베타계수의 안정성 분석에서는 중위험집단의 베타가 안정성이 높았으며 고위험집단에서 예측오차가 가장 크게 나타나 불안정하였다. 회계위험변수모형의 예측능력은 위험수준에 관계없이 단순모형보다 우수하여 베타예측에 회계정보의 유용성을 일반화시킬 수 있을 것이다. 셋째, 수익률 측정간격에 따른 베타계수의 안정성과 예측능력 분석에서는 월별수익률을 이용하는 경우보다 주별수익률을 이용하는 경우 추정베타의 안정성이 높고 베타계수 예측모형의 예측능력이 향상되는 것으로 나타났다. 넷째, OLS베타를 수정하지 않고 이용하는 경우보다 Bayesian 기법으로 수정한 Bayesian수정 베타를 이용할 경우 예측오차가 감소하여 Bayesian 수정기법의 유용성이 확인되었다.
