    김형산 | Maeng, Seung-jin | 심지훈 and 1other persons | 2013, 9(3) | pp.1~16 | number of Cited : 1
    In this study, a systematic and rational parameter of rainfall-runoff during the flood season was estimated using HEC-HMS (Hydrologic Engineering Center - Hydrologic Modeling System), a rainfall-runoff model, and unit hydrographs appropriate for the Sinheungcheon basin were selected. The initial parameter of Clark, SCS and Snyder hydrograph was estimated using an empirical formula commonly applied to domestic cases, and the curve number was estimated to be 81 in accordance with antecedent moisture condition-Ⅲ (AMC-Ⅲ). The optimized parameters were estimated by calibrating the parameters using the unit hydrograph on 2011 flood events, and the parameters were verified using flood events in 2012. For the runoff volume simulated through calibration and verification, each unit hydrograph was evaluated using the relative root mean square error (RRMSE) and the relative absolute error (RAE), the statistical variance. From its results, errors of Snyder unit hydrograph were found to be generally smaller compared to those of other unit hydrographs. In addition, one-way ANOVA was conducted to determine the significance level of each unit hydrograph. According to the one-way (Analysis of Variance, ANOVA) results, each unit hydrograph showed no significant difference at a 5% significance level. It is expected that if measured flow rate data of high quality as well as optimized parameter and unit hydrograph selected is used, more reliable runoff volume can be simulated.

    Jun Kye Won | Jun Byong Hee | Chang Deok Jang | 2013, 9(3) | pp.17~26 | number of Cited : 5
    It is difficult to predict the time of occurrence and location of debris flow disaster among sediment disasters due to heavy rainfalls, so it is an area that needs studies on the introduction of reduction facilities that can prevent it. The massive landslide and debris flow disaster that occurred in Gangwon-do in 2006 and the debris flow disasters that occurred in the whole area of Mt. Umyeon in Seocho-gu Seoul and the whole area of Cheonjeon-ri in Chuncheon-si in July 2011 can be said to be the incidents that show this clearly. This study predicted the volume of debris flow by whether reduction facilities (debris barriers) were installed for the research area in which a real-scale experiment was carried out and analyzed the reduction efficiency of the debris flow reduction facilities. For the prediction of the debris flow volume, an 1-dimensional numerical model analysis was used, which could simulate erosion and deposition. As a result of the analysis of the debris flow volume dividing the flow section of the debris flow into up-stream, down-stream and outlet, it was analyzed that installing reduction facilities had a reduction efficiency of approximately 27% for the stream-flow.

    Park Jung Min | 방정수 | HONG SUNG WOON and 1other persons | 2013, 9(3) | pp.89~110 | number of Cited : 3
    This study aims to analyze rate of implementation of basic and paramedic emergency care and the aspects of emergency care by EMT-Paramedics. For the study methods for this purpose, comparison groups for rural and urban models of each centers were selected to analyze the administration of the paramedics emergency care. And opinions of EMT-Paramedics on paramedics emergency care were collected through a survey and proposed obstacles and items for improvements in the paramedic emergency care. The statistical analysis on emergency activity by selecting rural and urban model showed that the rate of administration for basic emergency care was high in both models, whereas paramedic emergency care was very poor both models. According to the survey analysis of emergency medical technicians, they proposed that when transporting the patients within the short distance of 20 minutes of EMS activity time, quick transport to the hospital is required after basic emergency care. In the next study, our purpose was to analyze the obstacles to the paramedics emergency care and propose solutions for improvement through analysis of survey. First of all, many technicians appealed about the shortage of emergency technicians who can perform emergency care in the ambulance vehicle for two people including the driver and the legal limitations of the EMT-Paramedic's sphere of work and administration of basic emergency care. To improve the current situation, proposals have been made in the order of : placement of three qualified person(s) per ambulance vehicle, legal reformation of EMT-Paramedics' sphere of work, improvement of emergency care performance through participation in professional education, necessity of indirect medical control based on service guidance and stimulation of direct medical control and improvement in the awareness on emergency care for emergency medical technicians.

    Rapid Changing Environment

    Cho, Dong-Woon | Park Dong Kyun | 2013, 9(3) | pp.137~154 | number of Cited : 6
    Crime and delinquency in Korea are exceedingly widespread and pervasive. It will be clear that this condition is not the result of chance. Concern about crime in Korea has risen sharply. Not only has the crime rate increased continuously, but the nature of criminal acts committed has also changed. On the whole, crimes have become more vicious, impersonal, "senseless", and hence more alarming. So, crime have become one of the most serious problem in Korea. The most visible element in the criminal justice system is the police. Police have a number of very significant duties ranging from providing civic assistance to anyone who needs it - sick and old people, children - to detecting crime, apprehending criminals, appearing in courts as prosecution witnesses, and other crime-related activities. The police are the part of the criminal justice system in direct daily contact both with crime and the public. In modern democratic societies the police bear the primary responsibility for ensuring public safety because law enforcement is viewed as the primary solution to crime. The functions of policing are complicated. The range of police functions remains so broad and interwined as to make separation of theses functions impossible. Police functions are connected not only with the functions of other criminal justice components like courts and corrections but also with diverse governmental and social service agencies. The police are not separate from the people. and they draw their authority from the will and consent of the people. The police are the instrument of the people to achieve and maintain order: their efforts are founded on principles of public service and ultimate responsibility to the public. Policing has been undergoing rapid change. In the first decade of the twenty-first century, police agencies have been given an additional mission-the prevention of terrorism. To carry out this mission, police officers are being trained to be the first responders to terrorist scenes, to gather intelligence on terrorists, and to work closely with the federal government to make cities secure not only from crime but also from terrorists' act. In the twenty-first century, multiculturalism is quickly becoming an issue of primary importance. Police officers should perform the activities in order to improve their relationship with multicultural communities. It is very important for police officers who are engaged in problem solving to understand how, when, where, why criminal events occur, rather than merely responding them.

    Myounghee Shin | Paek Jin Sook | Kwak sun hye | 2013, 9(3) | pp.155~174 | number of Cited : 4
    The purpose of the present study is to explore crisis causer, crisis type, and crisis response strategy in the local government in Korea. To accomplish this purpose, 3,708 news articles on Suwon, Sungnam, Goyang, and Yongin City on three major broadcasting companies such as KBS, MBC, and SBS and five major national newspapers such as Chosun daily, Donga daily, Joongang daily, Kyunghyan daily and Hankyoreh daily were collected and 507 news articles were analyzed. Crisis causer was classified into internal or external, and organization or person. Crisis Content was classified into person factor, social environment factor, natural environment and accident factor. As a result, most of crisis causer is internal factor, and the local government was found in approximately 90% 0f the cases. Social environment was the greatest factor in crisis content. It was found three major response types ‘attack the accuser, excuse, corrective action’. In conclusion, crisis in the local government occurred from internal factor rather than external factor, and crisis response strategy was not various.

    Stress and Management Strategies in Korean Elderly

    Bae Jeong Yee | 김희현 | 양미경 and 3other persons | 2013, 9(3) | pp.175~194 | number of Cited : 13
    Today we are facing social problems of the elderly who are increaing in numbers and prolonging life expectency. Economic instability due to retire from workplace and the role change in the family and the society can cause a variety of problems and stress, which will have a negative impact on the quality of the elderly. So we examined the culture of the elderly and stress of those in Korea trying to set up a total stress management strategy , which is described through three points of view. To set up a total strategy to address the stress of the elderly as a social problem, we described them individually socioculturally and politically. Individual point of view, we did systematic studies on the stress perception and management according to individual's physical and mental characteristics. Sociocultural point of view, we mentioned a social need to respect the elderly and strengthen supporting system for them. Political point of view, we concluded that we need total welfare system for economically independent life of the elderly. We live in the timing of the elderly and no one can escape. That’s why we have to develop total solution and system to relieve the stress of the elderly
