In modern society, automobile is necessary vehicle. Automobile is a series of modern convenient. And the number of automobile is on the increase. But from you to year, automobile accident is on the increase, also. One of most reason that cause automobile accident is drowsiness driving. So, we plan to construct automobile system for drowsiness accident prevention for decreasing automobile accident. In this research, we built a drowsiness detecting device using EDA (Electro Dermal Activity) signal which is electric response in the human body skin. There are SIL (Skin Impedance Level) and SIR (Skin Impedance Response) in EDA. Mostly, SIL consists of DC element. On the other hand, SIL consists of AC element. We could detect the drowsiness condition with SIL and SIR signal.

In January, 2005, "railroad security law" was presented, preparing the systematic equipment that allows several railroad operators to consider the railroad security issue, and each of railroad operative institutions accepted such situation that construct the integral railroad security system, resulting in constructing the emergent system coping with the railroad fire accident through the relevant study business to improve the railroad security efficiency against fire. This study tried to present the studying direction on developing the emergent educational program coping with the railroad fire accident, which is distributed to the spot, about the railroad worker for improving the railroad security efficiency against fire through the education of systematic and efficient emergent countermeasure procedure of emergent system against the railroad fire accident.

화학물질은 사람에게 편리함을 주지만 적절하게 관리되지 않을 경우 화학물질의 유해 위험성으로 발생하는 피해는 다양하고 크다. 화학물질관리법에서는 유해화학물질의 안전한 관리와 취급시설에 대한 관리체계를 강화하였다. 하지만 최근 4년 동안에 발생한 화학사고를 분석한 결과 취급시설에서 발생한 화학사고는 증가 추세에 있으며, 이에 대한 예방대책이 추가적으로 필요한 것으로 나타났다. 이에 본 연구에서는 유해화학물질의 화학사고를 예방하기 위해서 최근 화학사고 사례연구를 통해 사고원인과 문제점을 분석하고 개선대책을 제시하였다.

2012년 구미 불산 누출사고 이후 화학사고의 심각성이 대두되고 있으나, 계속적으로 화학사고가 발생함에도 불구하고 임시방편적 대응 혹은 화학 사고에 대한 실질적 대응방안 마련을 위한 국가적 시스템 정비는 미비한 실정이다. 이제 일련의 화학사고가 단순히 기업이나 공장의 화학물질 사고를 넘어 전(全) 국가 및 사회 전반에 엄청난 파급효과를 일으키고 있다. 본 연구는 계속적으로 발생하고 있는 화학 사고에 있어 국가재난관리체계 확립방향의 길을 조금이나마 제시하기 위한 목적으로 연구되었으며, 이러한 연구의 목적을 도달하기 위해 현재 재난관리체계의 문제점, 화학 사고에 대한 재난관리 실패의 구조적 원인 및 사고 대응의 문제점 도출을 통해 화학사고 대응체계에 대한 개선방안을 제시하였다.

It is true that Aircraft accident investigation organization of Republic of Korea does not have independent role structurally and administratively. Also, in the event of an aviation accident it does not take the appropriate response and post-institutional measures for victims and their families support. With aware of this fact and to improvement this research paper present approach direction and suggestion of issues and implications for those by researching the operational practices of the United State's Victim Family support.

Chemical Accident Response Information System (CARIS) which has been designed for the efficient emergency response of chemical accidents produces the real-time atmospheric fields through the Regional Atmospheric Modeling System, RAMS. The previous studies were emphasized that improving an initial input data had more effective results in developing prediction ability of atmospheric model. In a continuous effort to improve an initial input data, we replaced the land-use dataset using in the RAMS, which is a high resolution USGS digital data constructed in April, 1993, with the latest land-use data of the Korea Ministry of Environment over the South Korea and simulated atmospheric fields for developing a real-time prediction in dispersion of chemicals. The results showed that the new land-use data was written in a standard RAMS format and shown the modified surface characteristics and the landscape heterogeneity resulting from land-use change. In the results of sensitivity experiment we got the improved atmospheric fields and assured that it will give more reliable real-time atmospheric fields to all users of CARIS for the dispersion forecast in associated with hazardous chemical releases as well as general air pollutants.

Objectives: Acute exposure to high concentrations of chemicals can occur when a chemical accident takes place. As such exposure can cause ongoing environmental pollution, such as in the soil and groundwater, there is a need for a tool that can assess health effects in the long term. The purpose of this study was assessing the health risks of residents living near a chemical accident site due to long-term exposure while considering the temporal concentration changes of the toxic chemicals leaked during the accident until their extinction in the environment using a multimedia environmental dynamics model. Methods: A health risk assessment was conducted on three cases of formaldehyde chemical accidents. In this study, health risk assessment was performed using a multimedia environmental dynamics model that considers the behavior of the atmosphere, soil, and water. In addition, the extinction period of formaldehyde in the environment was regarded as extinction in the environment when the concentration in the air and soil fell below the background concentration prior to the accident. The subjects of health risk assessment were classified into four groups according to age: 0-9 years old, 10-18 years old, 19-64 years old, and over 65 years old. Carcinogenic risk assessment by respiratory exposure and non-carcinogenic risk assessment by soil intake were conducted as well. Results: In the assessment of carcinogenic risk due to respiratory exposure, the excess carcinogenic risk did not exceed 1.0×10-6 in all three chemical accidents, so there was no health effect due to the formaldehyde chemical accident. As a result of the evaluation of non-carcinogenic risk due to soil intake, none of the three chemical accidents had a risk index of 1, so there was no health effect. For all three chemical accidents, the excess cancer risk and hazard index were the highest in the age group 0-9. Next, 10-18 years old, 65 years old or older, and 19-64 years old showed the highest risk. Conclusion: This study considers environmental changes after a chemical accident occurs and until the substance disappears from the environment. It also conducts a health risk assessment by reflecting the characteristics of the long-term persistence and concentration change over time. It is thought that it is of significance as a health risk assessment study reflecting the exposure characteristics of the accident substance for an actual chemical accident.

In January, 2005, the "Railroad Safety Act" was presented, preparing the systematic equipment that allows several railroad operators to consider the railroad safety issue, and each of the railroad operative institutions accepted such situation that the construction of the emergent system of coping, resulting in the construction of the emergent system of coping with the railroad fire accident through the relevant study to improve the railroad security efficiency against fire. This study tried to present the on developing the emergent educational program for coping with the KTX fire accident, which is distributed to the spot, to the railroad emergency staff for improving the railroad security efficiency against fire through the education of systematic and efficient emergent countermeasure procedures against fire accidents the fire accident in KTX.

The purpose of this study is to implement an emergency response procedure based on the scenario of the field of vehicles and provide more rapid and exact response program needed when train accidents happen. Therefore, we have made worst case combinations of accidents and prioritized the combinations. A number of accidents have been analyzed according to the type of, the people affected by, and the location of accident. Both horizontal and vertical response system have also been defined. Furthermore, Activity-Action Diagram has been applied to the emergency response scenario and action procedure of each group has been clearly systematized. Consequently, this paper provides a specific response system useful when train accidents happen.
