In Korea, hydrogen stations are being promoted and commercialized. However, the risk assessment for the hydrogen station is not clear. In particular, it is not clear how to calculate the risk and acceptable criteria for a hydrogen station. Therefore, in this study, three hydrogen stations being installed were selected and general risks were calculated and the social risk of each hydrogen station was calculated. In general, the method of risk assessment is individual/social risk. This is an individual's death rate considering the frequency of accidents, And the likelihood of death according to the number of nearby residents. These can be used to calculate the level of risk for a hydrogen station. However, this method of calculate risks is the criteria for judging whether it is acceptable are unclear. For this reason, this study investigated the allowable standards for foreign risks and considered that they were acceptable by applying the risks of selected domestic hydrogen stations.

In this research, the goal is to ascertain the potential danger when transporting hazardous material by considering the important elements that contribute to such situation, instead of relying on the quantitative risk assessment of fixed facilities. Also, this study will verify the social and personal risk according to damage zone limits, by applying the worst case scenario and the alternative scenario that occur during the transportation process. Moreover, it has selected the optimum transportation route for maximum safety. The result of this research could be used to construct a systematic emergency system that can minimize the damage from serious industrial accidents, by effectively decreasing the danger zone and forming a connection between the community, the society, and the industries according to such evaluations.

This study sought to identify gender-specific mechanisms of increased suicide rates during economic crises in South Korea. In order to address research aims, we focused on two international economic crises: IMF financial crisis in 1997, and international recession in 2008. This study provides three main findings. First, different mechanisms increased suicide rates during the two economic crises. Particularly, the high level of unemployment raised suicide rates during the 1997 IMF while the high level of working poor in the 2008 recession. Second, suicidal risk patterns for men and women differed at each period. The 1997 crisis which mostly affected full-time permanent workers had had relatively greater impacts on men suicide, whereas the 2008 crisis which affected precarious workers had done on women suicide. Finally, our finding indicated that these gender-specific risk patterns had been derived from the gendered labour market and male-friendly social policy. Placing women at the periphery of the labor market and using them as a buffer in times of crisis, governments failed to protect them from their economic difficulties. Suicide is fundamental and important public health and social problems. These findings suggest that the national suicide prevention strategy should pay attention to the social determinants of suicide through gendered as well as population health perspectives.

Demand for hydrogen as a renewable energy resource is increasing. However, unlike conventional fossil fuels, hydrogen requires a dedicated refueling station for fuel supply. A risk assessment of hydrogen refueling stations must be undertaken to secure the infrastructure. Therefore, in this study, a risk assessment for hydrogen refueling stations was conducted through both qualitative and quantitative risk assessments. For the qualitative evaluation, the hydrogen dispenser module was evaluated as two nodes using the hazard and operability (HAZOP) analysis. The risk due to filter clogging and high-pressure accidents was evaluated to be high according to the criticality estimation matrix. For the quantitative risk assessment, the Hydrogen Korea Risk Assessment Module (Hy-KoRAM) was used to indicate the shape of the fire and the range of damage impact, and to evaluate the individual and social risks. The individual risk level was determined of to be as low as reasonably practicable (ALARP). Additional safety measures proposed include placing the hydrogen refueling station about 100m away from public facilities. The social risk level was derived as 1E-04/year, with a frequency of approximately 10 deaths, falling within the ALARP range. As a result of the qualitative and quantitative risk assessments, additional safety measures for the process and a safety improvement plan are proposed through the establishment of a restricted area near the hydrogen refueling station.

유역의 홍수위험도를 산정하기 위해서는 홍수의 발생가능성과 유역의 홍수방어 능력 등의 환경적, 공학적 요소 이외에도 홍수로 인한 피해 및 영향의 종류에 따라 사회적, 경제적, 문화적, 공학적인 요소를 반영해야 한다. 이들 홍수 피해 요소는 그 중요성이나 특성별로 홍수로부터의 방어 비중이 다르게 설정될 수 있으며 지역별로도 차이를 나타낼 수 있다. 본 연구에서는 홍수위험도를 평가하기 위한 인자 선정에 지속가능성 평가 모형인 DPSIR (Driving force-Pressure-States-Impacts-Response)을 이용하여 환경적, 공학적 요소뿐만 아니라 사회적, 경제적, 문화적인 요소를 반영하고자 한다. DPSIR 모형은 유역의 영향 인자들을 지표로 선정하며 각 지표간의 유기적 관계를 반영하는 구조로 이루어져 홍수로 인하여 인자 간에 발생하는 반응을 묘사할 수 있는 장점이 있다. 또한 인자를 선정함에 있어서 전문가 및 이해당사자들의 견해에 따른 평가 지역의 특성과 지속적인 변화 가능성 등을 유기적으로 연결될 수 있도록 평가요소로 반영할 수 있다. 본 연구는 추가 연구를 통해 남한강의 하도구간 별로 적용될 예정이며 각 인자들에 대한 자료는 문헌조사, 통계자료 조사 및 수리학적 수치모형 등의 분석을 통해 수집될 예정이다. 인자들에 대한 가중치는 전문가들의 의견을 반영할 예정이다. 향후 하천의 구간별 상대적 홍수취약도를 사회, 경제, 문화, 환경적인 측면을 고려한 인자들을 반영하여 정량적으로 제시하므로 하천 구간별 치수관리 우선순위를 결정하는데 적극적으로 활용될 수 있다.

The objective of this research is to investigate how consumers react differently to financial and social risk/return, referred to as an 'asymmetric effect'. A lab-based experiment using a counterfeit but real-branded product examined the robustness of the statement that priming the interdependent versus independent self can result in differences in financial and social risk taking behavior in the context of counterfeit product purchase choice. Three hundred fifty-eight participants took part in the experiment. They were primed with different self-construal and evaluated purchase intention to the counterfeit product. As predicted, when evaluate in the context of loss claim of counterfeit product, risks were more activated, however, there was an asymmetric effect that self-construal priming had on financial and social risks. Interdependence primed participants were more likely to take a financial risk thus perform more purchase intention of counterfeit product and less likely to take a social risk than their independence primed counterparts, which led to lower purchase intention. The results of this research shed light on the various directions of future studies on the responses toward counterfeit product.

Recently risk management based on a quantitative assessment is considered to improve the level of safety in Korea. This paper focuses on the procedure of the quantitative risk assessment for natural gas pipelines. For that purpose, the methods to estimate failure frequency based on failure causes from European Gas Pipeline Incident Data Group and BG Transco, to analyze consequence caused by fire, and to calculate individual risk and societal risk have been proposed systematically in this paper. Risk criteria of individual risk and societal risk have been proposed by considering the environment of pipeline route in Korea. The proposed procedure of quantitative risk assessment may be useful for risk management during the planning and building stages of a new pipeline, and modification of buried pipeline.

Using a psychometric paradigm, risk perception of 30 hazards was investigated for three social groups-college students, experts of technologies, and employees of environmental organizations. The aim of this study was to examine psychological dimensions of risk perception, namely, to replicate the psychological dimensions - dread and knowledge -, which Slovic et al(1978; 1984; 1987) found and to forker explore discrepancies between societal groups. The results confirmed the same psychological dimensions Slovic et al have found. However, there are a number of significant differences in perceived risk such as perceived social benefits and other risk characteristics between three groups that suggest differences in ecological attitudes. The results were compared with those of Slovic et af and the nature of differences in risk perception among three groups were discussed.

The concept of a risk society, which was originally suggested by German sociologist Ulrich Beck, is insufficient to reveal how a certain risk materially and discursively unfolds on the ground and how its various dynamics are recognised by diverse actors because of the concept's spatial insensitivity. As an alternative approach, this paper introduces the concept of the riskscape, which was suggested by German geographer Detlef $M{\ddot{u}}ller$-Mahn, and analyses this concept in the context of the East Asian developmental state. It is meaningful that the East Asian developmental state thesis has strongly promoted the role of the state in stimulating national economic development in underdeveloped countries. However, it should also be noted that an active state role in encouraging modernisation and economic growth within a very short time produces consequences of what Beck calls 'manufactured risks', such as nuclear power plants. Therefore, it is essential to analyse the state in comprehending modernisation and the risk society in East Asia. More specifically, using the case of the location policy for nuclear power facilities, this article reveals how dominant social forces acting in and through the state constructed a national riskscape that minimises the gravity of local risks while prioritising the economic value of the national economy over local risks to produce rapid modernisation. Additionally, it is argued that a dominant national riskscape may become weak from competing with different riskscapes that are constructed based on contingency factors (e.g., political democratisation or a natural disaster). Based on these analyses, the article emphasises that interdisciplinary research using the concept of the riskscape is required to better explain the risks in East Asia.
