국립공원공단에서는 낙석위험지역에 낙석방지시설(낙석방지망, 낙석방지울타리, 피암터널 등)을 설치하거나 우회탐방로를 개설하는 등 안전 환경 조성을 위한 노력을 하고 있다. 그러나 기후변화에 따른 집중호우나 겨울철 이상 고온, 지반의 노령화로 인한 풍화와 절리현상으로 매년 낙석 발생이 증가하는 추세이며, 기존 낙석위험지역 관리방안에 대한 개선의 필요성이 대두되었다. 본 연구에서는 우리나라 국립공원 중 치악산 국립공원 황골지구를 대상으로 하여 낙석 발생의 위험이 있는 시범지역을 선정한 후 Rockfall 프로그램을 이용한 낙석 분석을 수행하였으며, 분석 결과에 따라 시범지역에 계측시스템과 결합한 대책공법을 적용하여 모니터링을 실시하였다. 이를 통해 낙석의 지속적 관리와 모니터링을 위한 낙석 관리방안을 제시하였다.

Steel and iron works have place many hazard or risk factor as a high temperature material, a high place, and so on. Accordingly, steel and iron works need system for risk assessment. In this paper, we development of risk assessment system for steel and iron works. In case study applied at the steel enterprise. The resultant, we can discovery that an human factor is an important question form risk assessment.

Purpose: The purpose of this study is to identify health risk behaviors in adolescents according to grade in school and to of for basic data to develop a health promotion for adolescents. Methods: A descriptive survey design was used and the SPSS 12.0 program was used for the data analysis, which included Chi-square test and Spearman correlation coefficients. The instrument for this study was based on the 1999 Youth Risk Behavior Surveillance System developed by the Centers for Disease Control and Prevention. Results: The results indicate that adolescent have an average of 2 risk behaviors out of 10 health risk behaviors categories. There are various types of risk behaviors, which art: different for each grade, such as physical fights, using alcohol, using heroin, weight control, and the lack of AIDS education. Physical fights, and the lack of AIDS education are common in the 9th grade, using alcohol, heroin, and weight control are common in the 11th grade. Physical fights were correlated with using cigarettes and sexual intercourses. Using alcohol was correlated with using cigarettes, heroin, sexual intercourses and weight controls. Using heroin was correlated with sexual intercourse and weight control. Conclusion: For the promotion of health in adolescents, different approaches to health education and prevention of health risk are needed for each grade because the health risk behaviors differ between grades.

As the types and usage of chemical increase, modern countries should protect their health and environment from the risk of hazardous chemical. Chemical accidents not only affect humans but also cause huge losses to the environment. Moreover, since its effects do not end in a short period of time, it is necessary to identify the extent of the damage and establish a prevention and response system in advance. In 2015, the Chemical Substances Management Act provided a system for assessing the impact on the people and the environment around the workplace. However, it is difficult to quantitatively evaluate the impact on environmental factors such as vegetation and aquatic, with the current hazard assessment methods. The purpose of this study is to analyze the quantitative risk of environmental receptors. This study improved the existing risk assessment formula by using the environmental vulnerability index and established the end point concentration criterion which can estimate the damage range to environmental media. To verify the results of the study, a virtual accident scenario was selected and a case study was conducted. As a result, the extent of impact on the environmental medium can be calculated, and the degree of environmental risk of the zone can be quantified through the risk analysis considering the environmental vulnerability. This study is expected to increase the reliability of the reliability of the existing risk anaylsis method beacause it is a risk analysis method that can be applied when the environmental factors are absolutely necessary and when the residents and environment are complex.

Esophageal cancer is a mjaor health problems in many parts of the world. A geographical information system (GIS) allows investigation of the geographical distribution of diseases. The purpose of the present study was to explore the relationship between esophageal cancer and effective climatic factors using GIS. The dispersion distribution and the relationship between environmental factors effective on cancer were measured using Arc GIS. The highest degree of spread was in Germi town and the least was in Ardabil city. There was a significant relationship between effective environmental factors and esophageal cancer in Ardabil province. The results indicated that environmental factors probably are influential in determining the incidence of esophageal cancer. Also, these results can be considered as a window to future comprehensive research on esophageal cancer and related risk factors.

This paper provides an integrated view on human and system interaction in advanced and automated systems, which adopting computerized multi-functional artifacts and complicated organizations, such as nuclear power plants, chemical plants, steel and semi-conduct manufacturing system. As current systems have advanced with various automated equipments but human operators from various organizations are involved in the systems, system safety still remains uncertain. Especially, a human operator plays an important role at the time of critical conditions that can lead to catastrophic accidents. The knowledge on human error helps a risk manager as well as a designer to create and control a more credible system. Several human error theories were reviewed and adopted for forming the integrated perspective: gulf of execution and evaluation; risk homeostasis; the ironies of automation; trust in automation; design affordance; distributed cognition; situation awareness; and plan delegation theory. The integrated perspective embraces human error theories within three levels of human-system interactions such as affordance level, psychological logic level and trust level. This paper argued that risk management process should dealt with human errors by providing (1) reasoning improvement; (2) support to situation awareness of operators; and (3) continuous monitoring on harmonization of human system interaction. This approach may help people to understand risk of human-system interaction failure characteristics and their countermeasures.
