    Development and Performance Evaluation of Environmentally Safe Foam Agents for Wildfire

    Kim Sung Yong | Heeyoung Ahn | Won Ho Cho and 3other persons | 2016, 12(11) | pp.19~26 | number of Cited : 0
    Abstract
    This study aims at developing environmentally friendly foaming agents with high fire-fighting performance by using natural surfactant compositions, and evaluating its basic property, environmental friendliness and extinguishing performance. The basic property test was carried out on the newly-developed agent in accordance with standards outlined by the Ministry of Public Safety and Security in Korea. As for environmental friendliness, the toxicity tests were conducted with water fleas and earthworms. An independently developed device testing wildfire suppression performance was used to assess extinguishing capability. The results showed the foaming agent met all required properties in both experiments before and after the property change. In the toxicity test on water fleas, immobilization occurred with 48.854mg/l foaming agent, but in the test on earthworms, even the 1,000mg/kg foaming agent did not cause any fatal effect. Its extinguishing performance was found to be 1.6 times greater than water.

    The Effect of the Changes in Wind Velocity and Slope on Forest Fire Behavior in Pinus densiflora Stands

    Kim Sung Yong | Heeyoung Ahn | Chun Geun Kwon and 1other persons | 2016, 12(11) | pp.27~36 | number of Cited : 1
    Abstract
    The objective of this study is to find out what effects the changes in slope and wind velocity has on characteristic changes in fire behavior through a simple burning experiment. Both upslope and downslope were considered for slope factor and the conditions of 0m/s, 2m/s, 4m/s and 6m/s were applied for wind velocity factor. The result of this study shows that, with the higher upslope and wind velocity, the flame temperature continues to increase up to 1,353.3°C. The rate of spread was also found to be as fast as 15m/min in the condition of 30° slope and 6m/s wind velocity. The conditional fire intensity was estimated to range from 78.11 kW/m to 5,982.23 kW/m and also increased with the higher slope and wind velocity, which was similar to findings in the literature for other countries. The result of this study will help to predict accurately the spread and intensity of forest fire.

    Issues and Development Direction of Disaster Safety Education for Disaster Vulnerable Groups - Focusing on Multicultural Family -

    JuHo Lee | 2016, 12(11) | pp.37~50 | number of Cited : 10
    Abstract
    As the number of foreign residents in Korea has reached over 2 million, the number of multicultural families is rapidly increasing as well. Multicultural families are relatively more vulnerable to disasters than average Korean families due to language barriers and cultural differences. For those who have low socioeconomic status, the risks associated with disasters become even greater. This high vulnerability indicates a lack of disaster safety and supporting systems for multicultural families. Thus, improving disaster safety management would be a long-term solution for challenges in disaster preparedness and response that multicultural families have faced. Currently, Korean disaster safety and supporting systems for multicultural families remain in early stages of development. This article aims to emphasize the role of disaster safety education for multicultural families. Based upon the findings from the case studies on Japan, this article identifies the policy recommendations under the four themes.

    The Relationship between Spatial Patterns of Forest Distribution and Forest Fire Characteristics in the Regional Administrative Unit in Korea

    LEE BYUNG DOO | Jung Eun Song | 2016, 12(11) | pp.51~61 | number of Cited : 1
    Abstract
    This study aims to identify the correlation between forest fire characteristics and forest distribution patterns in 16 regional administrative units in Korea. The canonical correlation analysis was conducted between forest fire characteristics and landscape matrices extracted from the forest cover map. The forest distribution varied by administration unit, in terms of the diversity of tree species, and fragmentation and aggregation of forest patches. The number of fires per unit area tended to be larger with less diversity of tree species, higher concentration of forest patches and simpler perimeter of a forest. The larger the average size of forest patches, the larger the burned area per fire. The shorter the distances among patches of pine forests, the longer the combustion time. This result contributes to the development of forest management strategies for reducing risks of forest fire.

    Development of the Non-revenue Water Analysis Equation through the Statistical Analysis of Main Parameter in Waterworks System in Incheon City

    Hyoung Geun Jo | Choi Gye Woon | Dong Woo Jang | 2016, 12(11) | pp.63~75 | number of Cited : 1
    Abstract
    In deciding priorities for waterworks maintenance, a scientific and systematic approach would be needed to examine and analyze the main parameters affecting the leakage, along with water demand quantity, water pressure, energy costs, and so forth. In this study, a statistical analysis was performed to estimate the physical parameters in waterworks maintenance with the highest correlation with the leakage. For this purpose, water distribution analysis was performed to assess the demand energy ratio. The formula of non-revenue water estimation consists of independent variables related with physical parameters for waterworks. Deterioration rate of pipes, demand energy ratio and water supply quantity at each demand point were used in a multiple regression equation for water distribution network analysis. If regional characteristics of distribution network and demand patterns are considered in developed formula, the estimated accuracy for calculating the non-revenue water rate will be improved.

    A Method of Evaluating and Controlling Corrosion Rate for Prevention of Water Quality Problems in Multiple Water Source

    Sung Hoon Shin | Jung Jongtai | 2016, 12(11) | pp.77~84 | number of Cited : 0
    Abstract
    In this study, we evaluated the impact on the contamination accident of water quality due to a pipe corrosion problem when using surface water and treated sewage water by the water blending method, and developed a controlling method. As result of experiment, carbon steel was rapidly corroded 14.7%~30.9% more than cast iron in surface water, treated sewage water, and surface water blended with treated sewage water. When injecting dissolved CO2 liquid slaked lime for corrosion control, corrosion reduction effect was found to be 39.15% for CaCO3 30mg/L and 54.7% for CaCO3 60mg/L compared to CaCO3 0mg/L. Both corrosion speed and corrosion degree increase with stirring speed. The Shannon Index was relatively low in blended water sample than either surface water or treated sewage water. While microorganism Betaproteobacteria became dominants in cast iron and PE, but microorganism did not become dominants in carbon steel.

    Predicting Disaster Vulnerability in Gangwon Province Using the Disaster Risk Index Based on RCP 8.5 Climate Change Scenarios

    Dae Ju Hwang | Suk Ho Lee | 김문모 and 1other persons | 2016, 12(11) | pp.85~97 | number of Cited : 4
    Abstract
    There is a growing concern over climate change all over the world, particularly due to the impact of extraordinary climate. The IPCC (Intergovernmental Panel on Climate Change) predicted that the annual average temperature of the earth would increase by 2.3°C in 2050 and by 4.8°C in 2100. It was also predicted that the annual average temperature in Korea would increase by 3.2°C in 2050 and by 6°C in 2100. This study aims to find out an effective measure against climate change that recently emerged as the global issue, through a disaster vulnerability analysis for flood, drought, intense heat, and heavy snow. The disaster vulnerability index was calculated separately for the present (2000) and the future (2020 and 2050). The results revealed that Yeongdong region and Wonju city were the most vulnerable in 2000. In addition, Sokcho, Gangneung, and Chuncheon cities were predicted to be the most vulnerable in 2020 and the central region of Gangwon would be the most vulnerable in 2050.

    The Need Analysis on Outplacement Competency of Discharged Soldiers

    Jeom Seok Kim | Hyo Son Park | 2016, 12(11) | pp.99~114 | number of Cited : 1
    Abstract
    This study examines the need of developing outplacement competency among discharged soldiers in Korea, focusing on vulnerable groups such as the officers who have less outplacement competency and the captains who receive limited pension support. The results are as follows: First, the recognition survey to the vulnerable soldiers reveals that their competency levels on all four categories, including attitude toward outplacement, job adaptation, outplacement knowledge and technical abilities, are lower than what is expected for successful outplacement. Second, it is found that the captains recognize their current outplacement competency lower than expected while the warrant officers consider their competency higher than expected. Third, the education and training for improving outplacement competency should be prioritized on outplacement knowledge and technical abilities rather than attitude and job adaptation. Finally, more time and efforts should be invested to cultivate their competency levels in these areas of priority.

    Resilience of Urban Communities in the Risk Society

    RHO JIN-CHUL | 2016, 12(11) | pp.115~128 | number of Cited : 2
    Abstract
    Resilience studies are interested in the adaptation of the system to changes in the environment that caused the fault and resistance to internal failure. Resilience is a concept that complements the analysis in the vulnerability of urban community structure, and refers to resistance and adaptation of the community to social change that caused the disaster. Disaster has been distributed very unequally, and the risk discourse considers risks as modified uncertainty due to the complexity of modern society based on the functional differentiation. The resilience of communities depends on whether and how they are capable of controlling conflict and disorder that emerge from dysfunction and a lack of resources caused by disaster. After the devastating disaster, the community generates a synergistic effect when exposed to the double-negative conflict. The resilience of the urban community operates not through stability but through the reproduction of instability.

    An Exploratory Study on the Subsidy for Fire Safety and Disaster Prevention Budget

    Chang Jae Kwak | Sangkyu Rheem | 2016, 12(11) | pp.129~142 | number of Cited : 3
    Abstract
    This study aims to suggest the policy alternatives for the improvement of the subsidy for fire safety and budget system for disaster prevention in Korea. In order to efficiently manage the disaster recovery tasks for local governments, it is important to establish standards for allocation of budget and its flexible execution. It is also necessary to determine the volume of budget and integrate the relevant budget items which are currently scattered across the multiple ministries. Establishment of a single budget management system will enhance efficiency in operating subsidy for fire safety and managing budget for safety from disaster. That would be beneficial for integrated budget process. Finally, it is recommended that financing programs for disaster prevention should be strictly evaluated based on performance and the evaluation outcomes should be used for the budget planning.

    An Exploratory Study on the Roles of the National and Local Assembly - A Governance Perspective on National Projects in Korea -

    Hyoung Sung Kim | JEONG BIN YIM | 2016, 12(11) | pp.143~160 | number of Cited : 0
    Abstract
    The governance paradigm has made diverse attempts for citizen participation and network from all countries of the world. The governance is now actively under discussion in Korea, but it is evaluated with a low level. Because the plan was bureaucratic and formal governance within limited region. This study presents the primary responsibilities of the national and local assembly in promoting governance, such as a rule-making for creating public sphere for public discourse and a direct participation through the configuration of a policy network. In addition, it highlights the importance of establishing multi-layered governance between the national and local assembly in the process of decision and administration for national projects. The suggestions from this study can strengthen the roles of the national and local assembly in expanding governance and governance culture.
