환경 오염과 지구 온난화의 위협이 구체적으로 모습을 드러내는 가운데 사회 전반적으로 녹색 경영의 중요성이 과거 어느 때보다 부각되고 있다. 이러한 현실 흐름을 반영하여 녹색 경영을 실행하는 기업들이 최근 들어 점점 증가하고 있다. 녹색 경영에 관한 기존 연구들에서는 녹색 경영의 의의와 중요성, 녹색 경영의 성과, 그리고 녹색 경영에 대한 영향 요인에 관하여 다루어 왔다. 본 논문에서는 녹색 경영 실행에 영향을 미치는 기업 내부의 촉진 동인에 관하여 살펴보았다. 66개 중소 기업에 대한 통계 분석 결과, 외부 연계, R&D 역량, 그리고 조직 문화 모두 기업의 녹색 경영 실행에 긍정적인 영향을 미치는 것으로 나타났다. 무엇보다도, 독립 변수들 가운데 조직 문화의 영향이 가장 두드러지는 것으로 파악되었다. 녹색 경영 요소들 간의 관계를 주로 살펴본 기존 연구들과 달리, 녹색 경영 실행에 대한 기업 본원적 요소의 영향에 관하여 살펴보았다는 점에서 본 논문은 의의가 적지 않다. 향후 연구에서는 더욱 다양한 기업 본원적 요소의 영향에 관하여 살펴볼 필요가 있을 것이다.

PURPOSES: The purpose of this study is to identify the key factors that influence a driver’s trust in road-freezing risk information METHODS : A survey was designed and conducted in the metropolitan area to analyze drivers’perception towards road-freezing risk information. A binary logistic regression model was developed based on the survey responses. The statistically significant model coefficients were determined and their odds ratios were calculated. Finally, they were considered as the key factors influencing drivers’trust in roadfreezing risk information. RESULTS : The developed binary logistic regression model was validated through statistical tests. The final results indicated that previous experiences of accidents on slippery roads, as well as route choice patterns are statistically significant, having 95% confidence levels. CONCLUSIONS : Previous experiences of accidents on slippery roads and road choice patterns are the factors that most significantly influence drivers’trust in road-freezing risk information. The findings of this study will be used as fundamental data in establishing tailored road-freezing risk mitigation procedures and services.

PURPOSES : This study deals with first traffic violations occurred by novice drivers, which may be associated with traffic accidents. The objective of this study is to identify what kinds of drivers' characteristics influence on duration till the first traffic violation. METHODS : For the study, Survival Analysis and Cox proportional hazard model, that are usually used in the medical field, were employed. Survival Analysis was conducted to investigate whether there exist differences in survival duration by each covariate, whereas Cox proportional hazard model was used to identify significant factors that affect survival duration till novice drivers violate traffic regulations for the first time after getting a driver license. RESULTS : The results of Survival Analysis indicate that female, age (less than 21), low-frequency examinee of written exam, and non-crash involved drivers have longer duration till the first violation compared to male, greater than 21 years old, high-frequency examinee of written exam, and crash involved drivers, respectively. For the Cox proportional hazard model, license class 1 acquisitor was found to increase the survival duration till the first traffic violation was made, while male, age of 21-24, age of 25-34, age of 45-54, and crash involved drivers were more likely to reduce the survival duration. CONCLUSIONS : Absolutely, traffic violation is closely related to traffic accidents and all of the drivers should keep the traffic regulations to enhance highway safety. The results of this study might provide some insights to construct safe road environments by controlling the factors that reduce the traffic violation duration of novice drivers.
