This paper attempts to incorporate three important factors-perceptions, behavior and valuation-in analysing consumers' responses to health risks from environmental pollutants. Using a survey sample of 500 consumers in the Chonbuk province area, this paper empirically investigated determinants of risk perceptions from using tap water as drinking water. Most consumers were considerably concerned about health risks from drinking tap water. Moreover, those subjective concerns were not random, but were systematically related to individuals' demographic variables such as age, gender, and family size. Those subjective beliefs also influenced respondents' purchase intentions on safer water bottles, in response to a contingent behavior question of presenting two types of water bottles. The technical risk information provided in the survey had significant effects on purchase intentions only when it was interacted with respondents' actual averting practice. In addition, the sample selection effects were present by eliminating respondents who decided not to purchase either of two types of water bottles. The potential selection bias had impacts on the coefficients of the price difference variable, and subsequently the estimates of the price increments for health risk reductions.

Due to the increase of size and complexity of construction project, the frequency of serious accidents in construction industry has been increased. Especially, the proportion of accidents in formwork of building construction site is very high, and many previous studies have been conducted to preventing them in the viewpoint of the diverse approaches. However, their effectiveness on accidents prevention was poor, and as a result, it is limited to consider the potential risks because many workers and managers tend not to be concerned with unsafe factors in formwork. Therefore, in this study, a realistic and proactive way for analyzing these potential risks was proposed in the manner of quantitatively assessing the potentials resulted from the unsafe factors in formwork. To verify the applicability of the proposed methodology, group survey was carried out, and the results were compared with those of the traditional importance-performance analysis(hereafter IPA) technique. Through the use of the proposed methodology, unsafe factors that were not found in the IPA but have potential risk were identified. Eventually, this study is expected to contribute to the proactive prevention of construction serious disaster accidents in formwork by enabling a more efficient management.

화학공정에서 발생하는 사고의 주요 원인으로는 조업자의 실수, 장치고장, 안전장치의 미비, 운전조건의 이상을 들 수 있다. 화학공정의 위험 분석은 HAZOP, FTA, ETA, 및 CA 등이 산업계에서 가장 유용하고 폭넓게 사용되고 있는 분석 방법이다. 이들 위험분석 기법 중에서 FTA(Fault Tree Analysis)는 사고의 세부적인 원인목록을 작성하여 해당사고의 구조를 파악할 수 있으며 복잡한 시스템내의 결함을 최소시간과 최소비용으로 효과적으로 예방할 수 있게 하는 정량적 위험성 평가 방법이다. 일반적으로 이 방법들은 전문가 집단에 의해 수행되기 때문에 전문가 집단의 능력과 투여되는 시간에 많이 비례하여 왔던 것이 사실이다. 이러한 이유로 인하여 위험분석방법의 자동화가 절실히 대두되고 있는 실정이다.(중략)
