The purpose of this study was to examine the structural models in which early cumulative risk factors affect children's language(indicated by expressive vocabularies) and social development(indicated by peer competence) at age 3 thorough their effects on the home learning environment. To examine the hypothesized models, the data of 1,725 families from the second and the fourth waves of the Panel Study of Korean Children was used. Correlation analysis and structural equation modeling were conducted to test the models. First, the cumulative risk factors at age 1 and 3 were highly correlated, implying the stability of the risk factors over time. The more cumulative risk factors at age 1 predicted the lower level of the home learning environment at age 3, which, in turn, was significantly related to both language and social development at age 3. However, the early cumulative risk factors did not directly influence later developmental outcomes. Moreover, the cumulative risk factors at age 3 were directly related to the child's language development, but neither social development northe home learning environment. In addition, the mediational role of the home learning environment (i.e., cumulative risk factors at age 1${\rightarrow}$home learning environment${\rightarrow}$language and social development) was statistically supported. In conclusion, the early cumulative risk factors in infancy indirectly predicted children's development at age 3 through the home learning environment. The practical implications for the early intervention and support for the families with infants who are experiencing multiple risk factors were discussed.

화학플랜트는 폭발성, 유독성 물질의 제조와 취급하므로 사고 발생에 의한 영향은 대단히 크고, 또한 사고 후 몇 년에 걸쳐 그 주변사회에 영향을 미친다. 따라서 화학공장의 화재, 폭발 및 독극물 누출에 의한 사고 등과 같은 가능한 모든 유형의 위험을 예측하고 예방하기 위해서 위험성 평가를 수행해야 한다. 이에 공정안전관리(Process Safety Management, PSM)에 대한 사회적인 관심이 증가하면서 많은 연구자들이 위험성 평가방법을 개발하여 잠재적 위험을 발견하고 안전대책(safety guard)을 제시하여 공정의 안전성을 확보하고자 노력해 왔다. 그러나 개발된 위험성 평가기법은 대부분 전문가들의 수작업을 통해서 이루어짐으로 신뢰성과 안전성을 항상 보장해 주지 못한다. 따라서 근래에 위험성 평가과정을 자동화하고자 하는 연구가 활발히 진행되고 있다.

이 논문은 설계상의 안전 및 완전한 정량적 위험성 평가에 의해 맞추는 것이 가능한 여러가지 방법(QRA: Quantitative risk analysis)에 촛점을 두면서, 위험성 평가의 방법론의 간략한 개요를 소개하고 있다. QRA의 결과는 단독 위험 및 그룹 혹은 사회적 위험으로써 보통 소개된다. 계산된 단독 risk는 자주 단독 위험 graph(IRG : Individual risk graph)와 단독 위험등고선(IRC : Individual risk contours)의 형으로 나타낸다. IRG와 IRC는 예를 들면 다음과 같은 사고의 시나리오로 계산된다. : 여러가지 기상조건 하에서 2kg/s의 암모니아의 유출을 1800s로 한다. 이 예는 그래프가 곡선의 상승을 나타내는 것이 확실하다. 마지막으로, QRA는 예를 들어서 토지이용계획 등에 유용한 수단으로 될 수 있다고 할 수 있다. 한편 화학플랜트의 안전에 대해서는, 위험성 평가를 위해 다른 방법이 유효하며, 불가피하다.

현대 사회는 모든 분야에서 다양한 분야들의 기술들이 융합되는 사회이며, 이로 인해 각종 환경적 위험 요소 등이 존재한다. 그중 한가지는 유해 가스에 의한 피해이다. 산업이 발전하고, 편의 시설등이 늘어나면서 다양한 시설들이 설치되고 있다. 하지만 이와 함께 시설물들이 가지는 위험도 또한 높아지고 있다. 이에 본 연구에서는 센서를 이용한 위험요소 탐지와 환경측정 자료를 기반으로 일상 생활에 접할 수 있는 위험요소를 파악하고 개선하고자 하였다. 진행은 유해성분을 측정할 수 있는 센서를 이용한 시스템을 구성하고, 자료 분석을 통한 개선사항를 도출하는 방식을 취하였다.

산업이 발달함에 따라 전기에너지의 사용량이 증가하게 되고 전기를 생산하기 위한 에너지원의 종류도 다양하게 된다. 전력생산을 위한 에너지원의 선택 역시 환경 영향, 사회경제적 측면 및 위험도에 대한 인식적인 측면에서 달라지게 된다. 국가 에너지 정책도 여러 가지 발전원들의 대중보건, 환경, 경제 및 사회에 미치는 영향을 고려하여 국가가 부여하는 목표 달성 가치에 따라 결정되므로 여러 발전원들간 위험도 관점에서의 객관적 비교 분석의 필요성이 대두된다.(중략)

This research was started in order to recognize the necessity of systematic and scientific approach to sinkholes, and to imply from an empirical point of view that a detailed evaluation method and measure for technique should be devised. As the result drew the risk factors that cause sinkholes by reflecting the opinions of water resources and ground experts, this research is expected to contribute to the development of a more systematic and pre-preventive evaluation index by preparing a countermeasure against sinkholes. In the future, it is necessary to develop an evaluation index toward the risk factors of sinkholes, in order to establish a scientific basis and objectivity that can determine priority, by subdividing the decision-making process that is required for preparing a countermeasure against sinkholes. In addition, a detailed methodology and related technique to measure each evaluation index should be continued to be discussed, in order to review the applicability of evaluation indices on actual sites.

Once drought occurs, it results in the extensive affected area and considerable socio-economic damages. Thus, it is necessary to assess drought risk and to prepare its counterplans. In this study, using various observation data on meteorological and socio-economical factors, drought risk was evaluated in South Korea. To quantify drought risk, Drought Hazard Index (DHI) was calculated based on the occurrence probability of drought, and Drought Vulnerability Index (DVI) was computed to reflect socio-economic consequences of drought. Drought Risk Index (DRI) was finally suggested by combining DHI and DVI. These indices were used to assess drought risk for different administrative districts of South Korea. The overall results show that the highest drought risk area was Jeolla Province where agricultural practice is concentrated. The drought risk map proposed in this study reflects regional characteristics, thus it could be utilized as a basic data for the establishment of drought preventive measures.

The present study examined the factors influencing individuals' risk information seeking and processing using the case of 2015 MERS outbreak in Korea. Analyses of two-wave online panel data demonstrated that perceived risk, negative affect, subjective norm, and information insufficiency predicted the risk information seeking/avoiding as well as information processing mode, which validates the Risk Information Seeking and Processing(RISP) model. More importantly, this study found new evidence that information seeking and systematic processing promoted MERS preventive behaviors. In addition, active SNS use moderated the link between perceived risk and negative affects about MERS crisis as well as the relationship between social normative pressure and to seek the risk related information.

Recently, the potential risks of tank lorry transportation from the petrochemical plant have been increasing, so the research was performed to build up the evaluation criterion of the transportation safety, as well as aggressive risk+assessment of a variety of chemical materials. This research was applied to the Maximum Credible Accident Analysis technique and modeled on the risk management of chemical transportation using the following four steps for risk evaluation, firstly the comparison of representative fype and standard of hand ling chemical materials transported by tank vehicles secondly, specific classification of potential hazards thirdly, grasp and recognition of virtual accident scenario at last, the risk evaluation of virtual accident scenario(qualitative/quantitative - chemical release modeling).

Although e-Finance has become more and more prevalent in everyday life, with the development of information technology, further development of e-Finance and commercial transactions has been limited. Therefore it is important for financial institutions to be aware of the significance of e-Finance risk and take appropriate actions. And an effective risk management function relies on a well-defined organization structure to eliminate gaps and minimize overlaps in risk management duties, responsibilities, and authorities. It defines and assigns risk management responsibilities, authorities, and accountabilities to appropriate personnel. The adequate organization of the risk management function is very important in the success of risk management.
