본 논문에서 교통 상해사고 위험요인들을 정량화하고, 위험요인들 중 교통 상해사고 원인에 가장 근접한 것이 무엇인가를 밝히려고 했다. 사례-조사 연구방법으로는 의학분야에서 많이 사용되는 환자-대조군 방법론을 채택하였다. 서울, 양평, 천안지역을 대상으로 1007년 중 입원환자를 중심으로 채혈조사와 설문조사를 통해 환자국 총 117건과 도로상에서의 일반운전자를 중심으로 호기 알콜테스트와 설문조사를 통한 대조군 총 483건을 수집하여 분석하였다. 승용차의 경우, 교통 상해사고 발생 위험요인으로 27개 항목들이 추출되고, 그 중 '도로의 부적합' 항목(RRR 값:4.057)을 포함 14개 항목이 교통 상해사고 원인에 가장 근접한 것으로 나타났다. 오토바이의 경우, 마찬가지 방법으로 최종적으로 '면허 보유기간' 항목(RRR값:3.733)을 선두로 하여 총 11개 항목이 교통 상해사고를 일으키는 원인에 가깝다는 결과를 얻었다. 또한, 두 경우 모두 인적 요인에 의한 결과피가 크기 때문에 이에 대한 경찰의 지속적인 단속이 필요함을 알 수 있었고, 상대위험도가 높게 나타난 순서대로 교통안전투자 우선순위에 정하면, 효율적인 교통 상해사고 감소를 기할 수 있으리라는 결론에 도달했다.

Construction has been well known as the industry in which accidents occur more often than other industries. The efforts to eliminate the accidents at construction sites need to be continuously conducted because they tend to cause the social problems such as massive loss of life and property. According to the Korea Occupational Safety and Health Agency (KOSHA), 26,570 (29.3 percent) out of 90,656 workers in total industrial accidents have been occurred in the construction industry in 2016. Particularly, the falling victims are the largest number, which is about 8,699. This number is increasing due to the increase of the large scale, high-rise, and complex construction structures and the various construction methods. In reality, there is a lack of analysis on the risk factors of safety accidents and preventive measures. Therefore, in this study, we have selected risk factors by analyzing the accident cases at construction sites. Based on the results, we conducted a safety practitioner-focused survey and had an interview with safety managers. In analyzing the cases, we have categorized them into three groups such as upper, middle, and lower and compared their statistical results. This study are expected to provide safety management guidelines with workers and safety managers to prevent previously fall accidents at construction site.

Purpose: Small-scale construction sites have insufficient systematic safety management activities, and due to the characteristics of the construction site, the production structure is complex due to external environmental factors, and the risk of construction equipment is very high. We would like to propose a checklist method among practical risk assessment techniques that can derive risk factors for disaster prevention at small construction sites and reduce disasters. Method: Risk factors were derived by analyzing literature research and disaster cases, and detailed work for a checklist of risk assessment suitable for small-scale construction sites was classified based on risk factor items. Result: Hazard factors were divided into 6 major categories, and 29 detailed types of work were classified based on actual work types, and 80 detailed works were classified accordingly. Conclusion: By arranging risk factors suitable for small-scale construction sites according to the classification system, the lack of expertise in the construction site can be supplemented, and risk factors can be derived more easily and disaster reduction can be expected through establishment of safety measures.

Research on sex offense has shown that sex offenders are very heterogeneous. Sex offenders are heterogeneous in their probability of risk of recidivism. Some sex offenders are known to be much higher in their tendencies to reactivate than others. The study examined the predictive and explanatory power of static and dynamic risk factors in STATIC-99 and HAGSOR-Dynamic which have been used in Korean correctional facilities since 2014. STATIC-99 and HAGSOR-Dynamic showed moderate predictive accuracy for all crimes(AUC = .737, AUC = .597, respectively, ps < .001). However, when examining sex crime alone, only STATIC-99 predicted recidivism significantly(AUC = .743, p < .001). The incremental predictive power of HAGSOR-Dynamic was confirmed; the explanatory power of Model 2 comprising both static and dynamic risk factors were significant beyond Model 1 comprising only static factors(∆χ²= 12.721, p < .001), but this tendency was only applied to the model of all crimes. These findings were discussed with implications of practicing the sex offender assessment and treatment.

The purpose of this study is empirically analyzing the effects of external factors(user knowledge, service characteristics, security), perceived risk, trust, ease of use, and usefulness on continuous customer acceptance in Internet banking. To achieve the goal, we develop the extended Technology Acceptance Model(Ex-TAM) based in the theoretical backgrounds of the Technology Acceptance Model(TAM). To test the new model(Ex-TAM), path analysis is performed by AMOS 4.0 package as a statistical tool. The finding indicate that 4 factors(service characteristics, ease of use, usefulness, trust) are significant. However, 2 factors(security, perceived risk) are not significant, user knowledge is partly significant.

Purpose: In this study, potential demographic, social, and economic factors causing tuberculosis were identified, and eight cities in South Chungcheong Province were compared and analyzed with the IPA method. Method: The factors potentially affecting the prevalence of tuberculosis were categorized demographically, socially, and economically, and selected through brainstorming. Furthermore, potential factors affecting tuberculosis were derived using the revised IPA. Based on this analysis, areas with a potential risk of tuberculosis were classified, and the following policy implications were suggested. Result: The analysis found the three cities of Nonsan, Boryeong, and Gongju to have the highest potential risk of tuberculosis, and the frequency of potential risk factors in the above three cities to be 6 or more. Thus, an urgent policy response to prevent tuberculosis in these regions is required. Conclusion: According to the results of this study, it is necessary to take potential risk factors into account when promoting tuberculosis prevention policies and projects in South Chungcheong Province.

The primary purpose of this study is to identify the determinants of the users' satisfaction and commitment in personal media. For these purposes, we developed a research model based on the literature reviews of personal media, perceived risk and interactivity, satisfaction, and commitment. This study has identified four dimensions in the concept of perceived risk, such as privacy risk, social risk, time loss risk, and economic risk, and three dimensions in the concept of perceived interactivity, such as active control, two-way communication, and responsiveness. In survey, data were collected from 428 male and female who have an experience in personal media. Data was analyzed factor analysis, reliability analysis, measurement model analysis, and structural model analysis by utilizing SPSS 15.0 and AMOS 5.0 program. Analysis results of research model indicate the following. Firstly, privacy risk, active control, two-way communication, and responsiveness are significantly related satisfaction. Secondly, privacy risk, time loss risk, economic risk, active control, and two-way communication are significantly related commitment. Thirdly, users' satisfaction has positive relationship with commitment in personal media. Based on these results, theoretical implications for relevant researchers and managerial implications for personal media vitalization and marketing strategy are discussed. Finally, limitations for this study and further research issues are suggested.

The purpose of this study is to verify the factors that affect the fear of crime by applying the risk interpretation model. Especially, whereas previous studies have not proven micro individual factor that the risk interpretation model had presented, This study includes micro individual elements such as neighborhood factor, perceived risk of crime, fears of crime as main variables. This study utilized secondary data of the National Crime Victimization Survey 2012, conducted by the Korean Institute of Criminology. In this study, multiple regression analysis of two stages and Sobel Test were conducted for verifying the individual influence of each independent variables and identifying the causal relationship between the variables set out in the risk analysis model. As the result, it appeared that the higher level of perceived risk of crime, neighborhood factor, crime experience, education, income cause the higher degree of the fear of crime. On the other hand, the lower degree of age was found to induce the higher level of the fear of crime. In addition, female showed the higher degree of the fear of crime than man. The causal relationship between the variables set out in the risk interpretation model was presented significantly in all variables, except for education.
