    Establishment of a Disaster Response Support System based on Public-Private Partnerships - Focused on Cooperation with a Private Institution Using Drone -

    Sohee Lee | kimmisong | 2019, 15(11) | pp.1~15 | number of Cited : 2
    Recently, drones are used widely in disaster areas, such as disaster relief and rescue, information collection and monitoring of affected areas. In particular, drones are highly useful to quickly identify the broader range of disaster damages. However, considering the specialized skills required for the operation of drones, training human resources and preparing equipment needs considerable time and budget. The public resources are not sufficient to monitor the damage, particularly in the case of large-scale disaster. This study aims at providing a new public-private cooperation model to support disaster response using private expertise and resources. In order to support disaster response during Typhoon Soulik in August 2018, we organized a collaborative team of emergency drone deployment based on the public-private cooperation and tested its efficacy. For a continuous operation and development of such activities based on public-private partnerships, increased efforts for institutionalization would be needed, including update of joint public-private organizations and operating systems, financial support, public relations, and routine training programs.

    Young Ran Oh | Ogcheol Lee | 2019, 15(11) | pp.17~26 | number of Cited : 0
    Due to the advancement of medical technology, the demand for organ transplantation through brain-dead organ donation from chronic patients has greatly increased. The purpose of the study was to investigate the knowledge and attitudes toward brain-dead organ donation among nurses who are more likely to encounter brain death cases or potential cases. The subjects were 107 nurses working in an emergency room, medical intensive care unit, surgical intensive care unit, and operating room of a general hospital in Seoul, Korea. The average score of knowledge about organ donation was 10.79 out of 20 and the average attitude score was 3.47 out of 5. The level of knowledge varies by age, career and educational exposure, while the level of attitude differs by workplaces. There was no significant correlation between knowledge and attitude, but knowledge had a significant positive correlation with cognitive attitude as a sub-factor. In conclusion, knowledge of organ donation among nurses in special departments was moderate, and their attitudes were rather positive. The results suggested the development of need-based educational programs on organ donation along with an intervention study to measure their educational effectiveness.

    Post-Disaster Inequality Factors on Depression and Anxiety among Elderly Victims in South Korea

    Kim, Jinhyun | 2019, 15(11) | pp.27~41 | number of Cited : 7
    The effects of disasters on individuals’ mental health differ by their sociodemographic and economic status. This study aims to identify how various determinants of post-disaster inequalities influence the elderly’s mental health such as depression and anxiety. This study utilized 666 seniors aged 65 or older among a total sample of 1,659 included in the 2017 survey data collected by the National Disaster Management Research Institute. The results from multiple regression analysis showed that female, older, and lower-income individuals experienced a higher level of depression and anxiety. On the other hand, when receiving adequate economic support and psychological counseling and having more social participation, they were less likely to be depressed and anxious after disasters. To improve mental health of elderly disaster victims, it is important to provide appropriate psychological counseling services as well as economic support. In addition, social capital of elderly victims should be enhanced through encouraging social participation and reducing conflict experiences.

    Determinants of Stress-Coping among Korean-Chinese Middle-aged Adults

    Lee, Jin-Min | Kim Kye Ha | Bin Yu | 2019, 15(11) | pp.43~56 | number of Cited : 0
    The purpose of this study is to investigate levels of stress, stress-coping, and self-esteem, along with their mutual relationships among Korean-Chinese middle-aged adults. Data were collected from 106 Korean-Chinese middle-aged adults aged 40 to 64 years living in Yanji, China from January to March 2017. To measure the level of stress, stress-coping, and self-esteem, a Visual Analogue Scale (VAS), a Ways of Coping Scale, and a Rosenberg Self-Esteem Scale were used. SPSS 23.0 was used for descriptive analysis, independent t-test, one-way ANOVA, Pearson correlation tests, and multiple regression analysis. The results show that, among the sub-factors of stress-coping, stress was positively associated with wishful thinking, while self-esteem was positively associated with problem focus, wishful thinking, social support, and positive viewpoint. The most important determinant of stress-coping was found as self-esteem. The results suggest further research on how to increase self-esteem as a way to intensify stress-coping among Korean-Chinese middle-aged adults.

    Self-Determination of People with Developmental Disabilities: Concepts, Misunderstandings and Scale Development - The Conceptualization for Self-determination Scale Development -

    Shin, Eunkyoung | Lee Woong | 2019, 15(11) | pp.57~87 | number of Cited : 1
    Abstract PDF
    This study aims to conceptualize self-determination of people with developmental disabilities in order to develop a scale that measures their level of self-determination in the social work fields. This study employed a methodology designed as three phases including theoretical analysis, fieldwork and final analysis, following the Hybrid model suggested by Schwartz-Barcoot and Kim (1986, 2000). The results showed that self-determination of people with developmental disabilities is characterized by five main components such as autonomy, psychological empowerment, self-realization, self-regulation and awareness of their own rights. There is also possibility of dynamic relationship among all the components of self-determination of people with developmental disability. However, the results of fieldwork suggest that some terms and expressions should be modified. The findings provide theoretical implications that can be used as the important basis for developing the measurement scale of self-determination among people with developmental disabilities.

    Effects of Leisure Activity in Elderly Welfare Center on Successful Aging - The Mediator Effect of Self-efficacy and Moderator Effect of Social Support -

    Choi, Soon Ok | 2019, 15(11) | pp.89~100 | number of Cited : 2
    The purpose of this study is to analyze the mediator effect of self-efficacy and the moderator effect of social support in relation to successful aging influenced by leisure activities offered by elderly welfare centers in South Korea. A total of 478 people aged 60 or older participated in the survey and 450 of them were used for analysis. Regression analyses were used to verify the mediator and moderator effects. According to the results of the analysis, leisure activities help increase self-efficacy and improve successful aging. Self-efficacy had mediator effects in the relationship between leisure activities and successful aging, while social support had moderator effects in the relationship between self-efficacy and successful aging. The findings suggested that the club activities in elderly welfare centers should be further expanded with various programs that encourage purpose-driven activities to improve self-efficacy and contact opportunities between generations to strengthen social support.

    A Risk Analysis by the Ratio of Basin Area to Capacity Based on the Reservoir Failures in South Korea

    Young Kyu Lee | 2019, 15(11) | pp.101~114 | number of Cited : 0
    There are about 17,000 reservoirs in South Korea and the reservoir failures repeat almost every year. Although many factors influence the failures, we focus on the effects of the ratio of basin area to capacity (B/C ratio) in this study. Especially, the effect of the B/C ratio looks more remarkable in small and medium-sized reservoirs which do not have sluice gates to control floods. First of all, we build up the database of reservoir failures in South Korea for a statistical analysis of the risks with B/C ratio. A total of 170 failures were collected from the multiple sources such as request of information disclosure, literature review and media report search. We failed to find out the specifications of 33 failures as they were abolished due to breach of reservoirs. All small and medium-sized reservoirs in South Korea were assigned into five categories by the B/C ratio, and the failure frequencies were analyzed in each category. The results showed a qualitative trend that the categories with a larger B/C ratio had a higher frequency, but the limitation was found in a quantitative analysis of risk sensitivity.

    Hydrogen Sulfide in Wastewater Generated by Hydrogen Induced Cracking Test: Cause and Safety Measures

    lee kyu yeol | IM YONG SUN | Hong-Min Kang and 3other persons | 2019, 15(11) | pp.115~124 | number of Cited : 1
    During the process of treating various wastewater, toxic gas such as hydrogen sulfide is generated due to the chemical reaction among unknown chemicals contained in wastewater, causing an accident that kills or injures workers and requires evacuation of people in neighboring areas. This study tested the reaction of sodium hydrogen sulfide generated during hydrogen induced cracking with sulfuric acid to confirm the occurrence of hydrogen sulphide and proposed safety countermeasures to prevent similar disasters from recurring. Hydrogen sulphide gas used during the process of hydrogen organic crack test reacts with sodium hydroxide in a neutralization tank and a gas scrubber to produce sodium hydrogen sulphide. Highly toxic hydrogen sulphide gases are produced violently when wastewater containing sodium hydrogen sulfide is mixed with sulfuric acid wastewater. In order to prevent the occurrence of harmful gases due to adverse reactions during wastewater treatment, the process of generating consigned wastewater should be well identified in advance, along with the detailed information on the composition and properties of the wastewater. In addition, more attention should be paid to adverse reactions of mixed wastewater.

    Statistical Estimation of Forest Fire Precaution Periods

    Sun Kyung Ryu | Byung Doo Lee | AHN HEEYOUNG and 1other persons | 2019, 15(11) | pp.125~136 | number of Cited : 0
    In order to maximize the efficiency of the limited resources for fire-fighting and prevention, it is important to set a forest fire precaution period by considering the temporal characteristics of forest fire occurrence and spread. In this study, the forest fire precaution periods were suggested based on statistical analysis of the national fire statistics data from 1991 to 2018. Multiple, ridge, and Lasso regression analyses were applied to identify the monthly (or 10 days) linear trend of fire occurrences, while k-means cluster analysis was used to select the precaution period. The fire occurrences in January, June, August and November have increased significantly over time, whilst those in March, April and May remained high without fluctuation over this period. The results suggest the extension of the fire precaution period in South Korea from 5 months (Spring: February 1 to May 15, Autumn: November 1 to December 15) to 8 months from mid-October to mid-June. This results from this study are expected to serve as statistical evidence for readjustment of forest fire precaution period in South Korea.

    An Empirical Study on Research and Development Capability and Organizational Innovation in Firefighting

    Soon Joong Yun | Jeong Gi Sung | Chae Jin | 2019, 15(11) | pp.137~151 | number of Cited : 0
    The research and development of firefighting organizations is a creative activity of knowledge accumulation for the protection of people and property. The purpose of this study is to empirically analyze various concepts such as fire service organization, research and development capability, and organizational innovation as a starting point of research and development on firefighting. The standardized regression coefficients from multiple regression analysis show that integrative reconciliation was the most influential variable on innovation in fire service organizations, followed by field application, task management, foundation construction, and professional manpower. However, it was identified that educational support, security of organization, network formation, security of budget, participatory research, and reflection of consumers’ needs were not statistically significant at the significance level of 0.05.

    Analyzing Human-Caused Accidents in Aviation Maintenance - Focusing on SHELL Model -

    CHOI BYEONG PIL | 2019, 15(11) | pp.153~166 | number of Cited : 0
    Whether aircraft accidents are caused by mechanical defects or human factors, the consequences are fatal to human life and property, which makes it critical to eliminate the causes and develop preventive measures. The research on human factors in aviation accident has been mainly conducted in relation to flight crews and then expanded into the field of aviation maintenance since the early 1990s. The basic concept of aeronautical maintenance is to maintain airworthiness in order to ensure the safety of the aircraft by perfect operation and service of all aircraft systems. This research studies on the theoretical background of human factors in the aviation field and examines the analytic model for the cause of aircraft accidents. In addition, it analyzes some cases which called attention to human factors in aircraft maintenance based on the ‘SHELL Model’, which is recognized as the basic theory of human factors in the aviation field.
