본 연구의 목적은 소방공무원들이 현장 활동 중에 석면함유 비산먼지로 위협되고 있는 현상에 대한 심각성을 사례 및 설문을 통해 발생 원인을 찾아 현장 활동 중에 석면노출을 효과적으로 예방하는데 있다. 소방관들의 현장 활동과 석면분진의 위험성에 대한 상관관계를 설문조사를 하여 분석하고 석면으로 인해 발생하는 석면폐암, 악성중피종과 같은 질병으로부터 소방공무원을 보호하고, 불합리한 여건들을 변화시킴으로써 조직운영의 최적화와 안전하고 쾌적한 근무여건을 통하여 소방공무원들이 현장 활동에서 치명적인 위해요소를 사전에 제거 하거하고자 한다. 또한 석면노출 기준에 따른 보호 장비 착용으로 철저한 소방 활동을 강화함은 물론, 소방 활동상 유해성인자의 심각성을 인식하고, 질환 피해보상에 대한 법적 제도를 마련하여, 아직까지 인정되고 있지 않은 질병에 대한 공무상 재해인정을 통한 제도적 미비점을 보완하여, 소방공무원의 사기진작 및 근무여건개선으로 대 국민 서비스 향상 등을 기대하고자 한다.

목조문화재의 화재특성을 보면 화재전파가 빠르고 화재가 발생하면 전소로 이어질 가능성이 큰 특징을 가지고 있다. 그러므로 화재의 예방과 초기 진압을 위해서는 상황을 정확히 인지할 수 있는 기술적인 대응과 더불어 인지된 문제를 조기에 대처할 수 있는 시스템이 필요하다. 이러한 기술을 첨단 유비쿼터스 기술에 의한 상황 감지, 그리고 상황에 따른 빠른 대처 즉, 진압에 활용하기 위해 본 연구에서는 유비쿼터스 센서 네트워크(USN) 기술, 불꽃감지기, 이미지 센서, USN 기반 문화재 방재 응용사례, 오작동 확인시스템 구현 등에 대해서 살펴보고 유비쿼터스형 문화재 방재시스템에 대해 불꽃감지기 오작동 확인시스템에 대해 실험하여 연구결과를 제시하였다.

Flooding induced scour has been long recognized as a major hazard to river-crossing bridges. Many studies in recent years have attempted to evaluate the effects of scour on the seismic performance of bridges, and probabilistic frameworks are usually adopted. However, direct and straightforward insight about how foundation scour affects bridges as a type of soil-foundation-structure system is usually understated. In this paper, we provide a comprehensive review of applied methods centering around seismic assessment of scoured bridges considering soil-foundation-structure interaction. When introducing these applied analysis and modeling methods, a simple bridge model is provided to demonstrate the use of these methods as a case study. Particularly, we propose the use of nonlinear modal pushover analysis as a rapid technique to model scoured bridge systems, and numerical validation and application of this procedure are given using the simple bridge model. All methods reviewed in this paper can serve as baseline components for performing probabilistic vulnerability or risk assessment for any river-crossing bridge system subject to flood-induced scour and earthquakes.

철도시스템은 전세계적으로 가장 안전한 교통수단으로 인식되고 있지만, 사고는 계속 발생되고 있다. 많은 하위부분으로 구성되어 있는 철도시스템의 특성상 사고위험을 완전히 방지하기는 어렵다. 철도사고는 다양한 원인이 복합적으로 작용하여 하나의 사건으로 표출되기 때문에 사고의 근원적 예방을 위해 사고사례의 사고모드를 분석하고, 사고모드에 영향을 미치는 인자들의 상관관계를 역 추적하는 시스템적인 접근은 매우 중요하다. 본 연구에서는 미국, 영국, 캐나다, 오스트레일리아의 국외사고사례분석을 수행하며 주요 위험인자를 도출하였다.

Although air, water, and noise pollutions have been widely recognized, electromagnetic forces(EMF) hazard has been rarely recognized as a pollution and very little studies has been done in this country. Thus, in this study electromagnetic forces radiated by various home appliances, once machines, and communication equipments were measured and so were several places radiating strong EMF such as subway stations and electric substations. Among the home appliances microwave oven senates lots of magnetic field and microwaves, and electric mattress does strong magnetic field. In video game room strong magnetic and considerable electric fields were measured. It was observed strong magnetic field inside of electric powered train and very strong magnetic and electric fields on some platforms. Hand-phone and car-phone radiate very hazardous level of microwaves to brain and that they rapidly come into wide use. In this study data base for various electric machines and places radiating strong EMFs were constructed and could be used for future epidemiological studies.

Fire is recognized as a significant hazard in a service life of a structure. Therefore there is a clear need to provide an improved understanding of the performance of material and structures in fire and to provide clear design guidance in order to progress safety design especially high rise building. It is the aim of this study to investigates and analyze the study on the development of evaluation methods for fire risk analysis of high-rise building.

Presently, in the countries, such as America and Japan which are better in socio-economical conditions than Korea, in Taiwan which is similar in them to us, and even in Thailand and Philippine which are thought lower in them, health education is taught as one of curricular subjects in elementary and secondary school levels. In Korea, however, the importance of teaching health education as a curricular subject has been recognized among many professionals of health since a long time ago. Along with current rapid development of polytechnique and industry, various kinds of serious health hazard have appeared even in our daily life, so it has been urgently needed that people have comprehensive knowledge and skills to resolve one's own health problems. Among various conditions needed to resolve the health problems in our society, it is one of the most effective precedures that health education is taught as a curricular subject at least in elementary and secondary school levels. For this, the followings are inevitable ; reformation of school health organization and laws involving health, development of teaching materials in health and training of health educators.

Signal words such as DANGER, WARNING, CAUTION, etc. have been used in order to transmit a potential hazard easily and quickly. But they were applied to a number of the sites without consistency. Thus, this study took Quantification Method and Cluster Analysis in order to judge the signal words corresponding to the urgency of situations, and to analyze whether signal words are used properly or not. According to the result of Quantification Method II signal words were most affected by Understanding, Severity and Likelihood in both student group and industrial worker group. And in Quantification Method III CAUTION corresponded to Immediacy and Understanding whereas NOTICE did to Receptivity, WARNING, DEADLY and DANCER did to Likelihood, Dangerousness and Severity. Finally, Cluster Analysis showed that CAUTION and NOTICE were recognized as similar words.

Higher plants provide valuable genetic assay systems for screening and monitoring environmental pollutants. They are now recognized as excellent indicators of mutagenic effects of environmental chemicals and are applicable for the detection of environmental mutagens both indoor and outdoor. 2,4-dichlorophenoxyacetic acid (2,4-D) is a herbicide commonly used in agriculture. The residues of 2,4-D are present in air, water, soil and edible plants. It constitutes a real hazard to the public health because it's wide spread use in agriculture. Genotoxic effects of 2,4-D on plant cells and potential of higher plants as a biomonitoring system for detecting chemical mutagens are evaluated. It is recommended that higher plant systems have been accepted by regulatory authorities as an alternative biomonitoring system for the detection of possible genetic damage resulting from pollution and the use of environmental chemicals.

Obstructive Sleep Apnea(OSA) is a form of sleep disordered breathing(SDB) characterized by the occurrence of episodes of complete or partial upper airway obstruction during sleep that is often quantified as the apnea-hyponea index(AHI). It is increasingly being recognized that OSA is a public health hazard and there is increasing evidence that it is associated with an increase in morbidity. Early recognition and diagnosis of this condition may lead to earlier treatments (eg, CPAP, Oral appliances) with reduction of the risk of metabolic disease, cardiovascular diseases, such as hypertension, ischemic heart disease, arrhythmias and pulmonary hypertension.
