  • The level crossing collision accident which comprises more than 90 percent of all level crossing accidents is one of the most serious safety problems. There is a critical need for providing safe strategy and is focusing on the level crossing information rather than measures at a grade crossing. This study is intended to develop technology for accident prevention and damage reduction based on accident cases analysis result and improvement direction to complement shortcomings of safety equipment of conventional level crossing and to establish safety of travelers(train, motor vehicle, person).

  • Objective : The paper aims to provide predictive coefficients via BIA for the assessment of body composition in children and adolescents to serve clinical as well as research purposes. Methods : Body composition via dual-energy x­ray absorptiometry (DXA) and bioelectric impedance as well as other anthropometric index were derived from meaurements on 1026 children and adolescents aged from 6 to 18 years from Beijing City. The best subset regression and principle component analysis were adopted to build the predictive coefficients with the logarithm of body composition via DXA as response variable. Results : Condition index ${\varphi}$ of fat-free mass multiple linear regression achieves 113.49 and 91.18 for males and females respectively, demonstrating severe multicollinearity among anthropometric indexes in children and adolescents. BIA predictive coefficients base on the best subset regression and principle component analysis boast a content predictive value for lean mass ($r^2$ = 0.9697 and 0.9664 for boys and girls respectively, p < 0.0001) and for Fat$\%$ ($r^2$ = 0.7705 and 0.6959 for boys and girls respectively, p < 0.0001). Conclusions : BIA method is applicable for the prediction of body composition for children and adolescents.

  • Chemical Accident Response Information System (CARIS) which has been designed for the efficient emergency response of chemical accidents produces the real-time atmospheric fields through the Regional Atmospheric Modeling System, RAMS. The previous studies were emphasized that improving an initial input data had more effective results in developing prediction ability of atmospheric model. In a continuous effort to improve an initial input data, we replaced the land-use dataset using in the RAMS, which is a high resolution USGS digital data constructed in April, 1993, with the latest land-use data of the Korea Ministry of Environment over the South Korea and simulated atmospheric fields for developing a real-time prediction in dispersion of chemicals. The results showed that the new land-use data was written in a standard RAMS format and shown the modified surface characteristics and the landscape heterogeneity resulting from land-use change. In the results of sensitivity experiment we got the improved atmospheric fields and assured that it will give more reliable real-time atmospheric fields to all users of CARIS for the dispersion forecast in associated with hazardous chemical releases as well as general air pollutants.

  • 도시화 산업화로 인하여 도시지역과 농촌지역은 인구 구조, 경제수준, 인프라 등 다양한 특성에서 차이를 보이고 있으나 재난안전대책은 이러한 특성을 반영하지 못하고 있는 것이 현실이다. 다양한 분야에서 도시와 농촌을 비교하는 연구를 실시하고 있지만 재난 및 안전 관리적 측면에서의 연구는 전무한 실정이다. 지역의 재난관리 대책 마련 시 도시지역 및 농촌지역 주민들의 자신이 살고 있는 지역에 대한 체감안전도, 문제점, 요구사항이 무엇인지 파악하고 주민의견을 반영할 필요가 있다. 따라서 본 연구에서는 도시와 농촌의 재난환경에 관한 이론적 검토를 실시하였으며, 도시지역과 농촌지역에 거주하고 있는 주민들의 재난안전에 대한 인식을 알아보기 위해 주민들에게 재난안전(비구조적요소, 구조적요소, 인적요소, 환경적요소)에 관한 의식조사를 실시하였다. 또한 이를 토대로 향후 도시지역과 농촌지역의 재난관리계획 수립 시 반영사항을 도출하였다.

  • The virus isolated from patients with severe pneumonia of unknown etiology in Wuhan City, Hubei province in China was termed SARS-CoV-2 and the World Health Organization (WHO) named the disease caused by this virus as coronavirus disease 2019 (COVID-19). The COVID-19 infection has spread rapidly and become a pandemic. In July 2020, there were 13.25 million infected patients and over 570,000 deaths worldwide, and 13,711 infected patients and 294 deaths were reported in South Korea. Since the primary mode of transmission of COVID-19 is through respiratory droplets, the importance of preventive measures, including social distancing, has become important in daily life. In response to the continuous spread of COVID-19, this study developed three guidelines for preventing COVID-19 for the food service industry including childcare centers, institutional foodservices and restaurants by the integration of the manual of controlling foodborne illness. These are included the COVID-19 prevention action methods for food deliverers, for food service administrator, for foodservice works and for customers. All guidelines were designed for easy understanding using illustrations and have been systematically explained subject wise. Thus, these COVID-19 prevention guidelines can be appropriately applied depending on the specific situation and workplace. In addition, they are worthy as educational materials that contribute to the food safety.

  • This study aimed to compare fear and prevention behaviors on accidents between mothers and teachers in family childcare centers. The participants were 117 mothers whose children were 0~2 year-olds and 121 teachers. Based on Hendrickson(2008) and Reichert & Henricks(1996), the scale was developed by the researcher, and it was composed of fear and prevention behaviors on accident. The data were analyzed using descriptive statistics and $x^2$ analysis. Results showed that mothers feared fall accidents and step-on-accidents while teachers feared suffocation accidents and liability for injury medical fee. Also, mothers did more prevention behaviors on use of car seats than teachers, whereas teachers did more behaviors on walk safety, custody of drugs and dangerous articles, and food safety.

  • The study aimed to improve the injury belief, injury prevention behavior, and safety fulfillment confidence of teachers of infants and toddlers in childcare centers. The study subjects were 376 teachers who were assigned to either the intervention group or the control group. The intervention group participated in an Injury Prevention Program for infants and toddlers for 100 minutes once a week for a total of 5 sessions, while the control group did not. The collected data were statistically analyzed through the independent t-test and paired t-test. The injury belief and injury prevention behavior test scores of the teachers in the intervention group were significantly increased compared to those in the control group after the completion of the five-week program.

  • Resilience has been suggested as a new paradigm of disaster management which reduces losses against disasters under the uncertain circumstances. The purpose of this study is to define the concept and to set up the objectives of urban resilience for disaster management. The common concept and components of resilience were analyzed by examining recent studies on resilience. The resilience was defined as "a capacity of physical and social urban elements adapting and recovering against disaster for better condition" and the five objectives of resilience - Robustness, Redundancy, Resourcefulness, Rapidity, and Regional Competency - were derived from the review of literatures. The major disasters and accidents were analyzed focused on those objectives. The concept and objectives of urban resilience could be used as a guidance for disaster prevention planning and disaster management processes.

  • Purpose: This study was conducted to determine the effects of a fall prevention program on falls, physical function, psychological function, and home environmental safety in frail elders living at home in rural communities. Methods: The design of this study was a nonequivalent control group pre posttest design. The study was conducted from July to November, 2012 with 30 participants in the experimental group and 30 in the control group. Participants were registered at the public health center of E County. The prevention program on falls consisted of laughter therapy, exercise, foot care and education. The program was provided once a week for 8 weeks and each session lasted 80 minutes. Results: The risk score for falls and depression in the experimental group decreased significantly compared with scores for the control group. Compliance with prevention behavior related to falls, knowledge score on falls, safety scores of home environment, physical balance, muscle strength of lower extremities, and self-efficacy for fall prevention significantly increased in the experimental group compared with the control group. Conclusion: These results suggest that the prevention program on falls is effective for the prevention of falls in frail elders living at home.
