    Improvement on the Spill Risk of a Vehicle Transporting Hydrogen Chloride

    신창현 | BYUNGCHOL, MA | Park, Jai-hak | 2016, 12(9) | pp.1~17 | number of Cited : 0
    Abstract
    According to the recent statistics on chemical accidents, 72 cases resulted from transport vehicles and 14 of those cases spilled hydrochloric acid, the most frequently spilled chemical from the accidents. A small leakage occurred in most of the chemical accidents, but the massive spill occurred due to the vehicle rollover. When hydrochloric acid reacts with fire water or rain after leakage, extremely toxic gases such as hydrogen chloride are generated and spread into the atmosphere, causing severe damage. Since responding to vehicle accident is relatively more difficult, it is important to take preventive measures to reduce the risks considering the worst-case scenario such as the rollover. Therefore, this study used ALOHA to compare the end points of ERPG for the rollover accident between the existing vehicle model and an improved one, which confirmed that the improved vehicle could reduce the end points by an average of about 33.3 to 40%.

    Testing the Acceptance and Diffusion Model of Internet Rumor - Focusing on Helping Motivation for Nuclear Risk Information -

    Ryu Yeon Jae | Kim SeoYong | 2016, 12(9) | pp.19~37 | number of Cited : 3
    Abstract
    This study was conducted to explore a process in which nuclear risk information as a rumor is accepted in the internet and spread to internet users. We assumed that (1) the distrust of government information and the reliability of internet information influence the degree of rumor acceptance, (2) the rumor acceptance affects change of attitude, (3) change of attitude increases the intention of information spread, and (4) the influence on information spread intention is moderated by helping motivation levels (i.e. helping development policies, helping others). Our results confirmed all the assumed propositions are true, which significantly highlight the process of rumor spread. In particular, the motivation of helping development policies should moderate the effect of distrust of government information on information spread intention, and spread intention was moderated by helping motivation among people who trust internet information and change their attitude.

    The Effects of Organizational Learning on Job Satisfaction among Firefighters

    Sangkyu Rheem | 2016, 12(9) | pp.57~67 | number of Cited : 2
    Abstract
    This study aims to find out the main determinants of firefighters’ job satisfaction and provide policy direction for improving job satisfaction among firefighters in Korea who work in poor surroundings. The determinants found in this study include organizational learning, leadership of vision and problem solving, and organizational commitment. Interestingly, these determinants vary by job class. Organizational learning and organizational commitment were found to be critical determinants for firefighting classes, while leadership of vision and organizational commitment were for search and rescue classes. Therefore, it is necessary to develop policy alternatives tailored to their job classes in order to enhance the level of job satisfaction among firefighters in Korea.

    Estimating the Economic Value of Dams against Climate Change Risk - A Case Study on Paldang Lake -

    Oh, Hee-Kyun | Lee, Hee Chan | 2016, 12(9) | pp.69~84 | number of Cited : 0
    Abstract
    The aim of this study was to estimate the economic value of the Paldang dam for its function against climate change. We utilized the choice experiment method with three attributes such as drought protection (DP), flood prevention (FP), and water purification (WP), all of which were determined at three levels: status quo, partial improvement, and full improvement. From the survey data from 1,096 households living in the Seoul, Gyeonggi and Incheon Metropolitan Areas, 6,576 responses were used in the model estimation. The main results derived from a conditional logit model demonstrated that a larger willingness to pay (WTP) for improvements of the functions of the Paldang dam was associated with a higher level of the DP, FP and WP functions. The marginal WTP for DP, FP, and WP were respectively computed as 4,165 KRW, 1,583 KRW, and 12,003 KRW. Consequently, the total value of commonweal function was calculated as 17,751 KRW.

    A Study on Organizational Changes of the Korean Financial Companies Operating in China

    CHOI JUNG SEOK | Choi seok gyu | 2016, 12(9) | pp.85~96 | number of Cited : 1
    Abstract
    This study analyzes the organization changes of the Korean financial companies operating in China, focusing on the issue changes of the management agency. First of all, the sources of issue changes in the Korean financial companies operating in China vary company size, and the management agency appeared to influence a change in the organizational structure of the owner-manager system companies. Second, there was a positive correlation between the human resource relocation and the changes in product demand in the financial markets responding to the rapidly change financial environment in China. Third, China’s financial market continues to be centered on the state-owned commercial banks which are mostly owned by the government, such as binary (Huijin) company and the Chinese Ministry of Finance.

    A Study for Improvement Direction and Reality of Disaster Management System in Korea - A Review Focused on Basic Safety Management Plan -

    Yoon, Sang-hoon | Jin Dong Shin | So Yeon Pak and 2other persons | 2016, 12(9) | pp.97~106 | number of Cited : 4
    Abstract
    This research reviewed the problems of the national and regional safety management plan in Korea, along with the cases from foreign countries, in order to propose policy directions. We have learned as a result of this study that the Korea’s safety management plan had four major problems; limited measures to address new and composite disasters, excessive bureaucracy and formality, insufficient connectivity between national and regional plans, and insufficient consideration of regional characteristics. The most imminent factor to resolve the problems in disaster management system in Korea was found to determine the selection, analysis, evaluation and monitoring processes of developing the risk register in advance, which should be needed to establish the plans for safety management. In addition, re-evaluation and adjustment of appropriate time and enhancement of plan connectivity could function as a fundamental manual in case of disasters or safety accidents. We argue that the lessons from the foreign cases examined in this study should be applied and adjusted to the Korean context in order to establish more efficient disaster safety management plans and system in Korea.

    Identifying the Effects of Jurisdiction-Related Characteristics on the Highway Safety of Vulnerable Users

    성중기 | Kim, Do-Gyeong | 2016, 12(9) | pp.107~117 | number of Cited : 1
    Abstract
    The main objective of this study is to enhance highway safety among vulnerable users such as children and elderly people through the investigation of crash characteristics and travel behaviors affected by a rapid demographic change. Both the conventional linear regression model and a beta regression model were estimated with 11 independent variables. No variable was found significant by the conventional regression model at 95% significance level whereas seven variables turned out to be significant in the beta regression model, indicating that it is very important to consider the characteristics of a dependent variable in model estimation process. It is found that two independent variables were positively related with the ratio of crash occurrence while the other five variables were negatively associated.

    An Analysis of Variation in Design Drought Rainfall Based on Climate Change

    Seung Wook Lee | Maeng, Seung-jin | Hyung San Kim and 1other persons | 2016, 12(9) | pp.119~128 | number of Cited : 0
    Abstract
    South Korea has experienced an increased number of flood disasters following the increased frequency of local rainfall occurrence. With an increasing frequency of floods, drought frequency and duration of drought have also increased. The rainfall and meteorological analysis showed that droughts occurred every 5 years, including the worst drought in 2015. Although Chungbuk province has an annual average rainfall of 1,212.7mm, it had 650.3mm in 2015 which was only 53.8% of normal year rainfall. In this study, the L-moment parameters were determined by applying an appropriate probability distribution to the annual minimum series data according to climate change scenarios at 5 rainfall stations in Chungbuk province. The frequency of drought rainfalls was computed for each continuing time by utilizing the appropriate probability distribution in the L-moment method. The drought rainfall computed in this paper can be used as fundamental data for designing drought measures and estimating regional drought rainfall.

    In Search of Deterrence Strategy against Cyber Terrorism to Strengthen the National Security

    Lee Dae Sung | Joo seong bhin | 2016, 12(9) | pp.129~142 | number of Cited : 1
    Abstract
    Recently, a growing number of researchers have expanded the discussion of deterrence strategy to address a host of new cyber threats. South Korea’s allies and neighboring countries have begun to address terrorism beyond its conventional approach to cyber defense, from reactive to proactive, which may include international deterrence. South Korea should join this trend from passive to active approach to cyber terrorism, such as deterrence by denial and deterrence by punishment. Deterrence by denial is a strategy in which an adversary is physically prevented from acquiring a threatening technology, while deterrence by punishment is a strategy of last resort. Since it appears that deterrence by denial was not possible or has failed, the South Korean government should go beyond its passive attitude and develop timely and appropriate policies.

    A Strategy for Overcoming Disaster Vulnerability and Improving Resilience - Focusing on the Conceptual Integration of Disaster Vulnerability and Resilience -

    Yang Gi Geun | 2016, 12(9) | pp.143~155 | number of Cited : 15
    Abstract PDF
    While vulnerability is based on insecure conditions that build up hazards creating disasters and interact with each other, resilience is based on resources that work as a countermeasure against disasters. Resilience emerges after a disaster, but vulnerability emerges before a disaster. Disaster probability is high in communities with a high level of vulnerability. Reducing the level of vulnerability tends to increase the capability of flexible reaction and recovery probability. What differentiates this study from previous studies is the integration of disaster vulnerability and resilience which used to be discussed separately. Based on a conceptual integration of vulnerability and resilience, this study assessed the level of disaster vulnerability status in Korea focusing on human, economic, social and institutional capital at both individual and group level and suggested a strategy to improve resilience.

    Assessing Broadcasting News of Disaster - A Focus on the Sewol Ferry Disaster in South Korea -

    Yung Wook Kim | Ji Young Lee | 2016, 12(9) | pp.157~178 | number of Cited : 0
    Abstract PDF
    This paper examines major elements of broadcasting news on the South Korean Sewol ferry disaster, including frames, sources and visuals. The episodic and responsibility frames were frequently used in disaster news. Official government-related sources were primarily used in most news frames, whereas episodic, human interest, and community-atonement frames were mostly used when citizen and victim sources appeared. Close-up shots were contained in episodic and human interest frames. Episodic frame news used computer graphics (CG) more often than thematic news while the attribution of responsibility frame used CG elements the most among content-based news frames.

    Disaster Preparedness within the Resiliency Management Framework - A Case of Sarasota Bay Ecosystem -

    Lee Hye Kyung | KIm Hwanyong | 2016, 12(9) | pp.179~187 | number of Cited : 0
    Abstract
    Diagnosing a region’s ecosystem and its level of resiliency would provide an alternative viewpoint of risk management and disaster preparedness. As a result, the region would become more resilient to its environmental vulnerability and long-lasting human impact on the ecosystem. This study is intended to provide a framework to diagnose a region’s natural resiliency by assessing possible disturbance, threshold, and the adaptive cycle. These three are critical components to properly understand a region’s natural resiliency and thus frequently implemented in various research projects. Using the three key components, we analyzed the levels of resiliency of Sarasota Bay ecosystem in the state of Florida in the U.S. The study findings provide policy guidelines and recommendations for a better disaster preparedness strategy.
