The time for evacuation of residents in emergency planning zone(EPZ) of Uljin nuclear site in case of a radiological emergency was estimated with traffic analysis. Evacuees were classified into 4 groups by considering population density, local jurisdictions, and whether they ate residents or transients. The survey to investigate the behavioral characteristics of the residents was made for 200 households and included a hypothetical scenario explaining the accident situation and questions such as dwelling place, time demand for evacuation preparation transportation means for evacuation, sheltering place, and evacuation direction. The microscopic traffic simulation model, CORSIM, was used to simulate the behavior of evacuating vehicles on networks. The results showed that the evacuation time required for total vehicles to move out from EPZ took longer in the daytime than at night in spite that the delay times at intersections were longer at night than in the daytime. This was analyzed due to the differences of the trip generation time distribution. To validate whether the CORSIM model fan appropriately simulate the congested traffic phenomena assumable in case of emergency, a benchmark study was conducted at an intersection without an actuated traffic signal near Uljin site during the traffic peak-time in the morning. This study indicated that the predicted output by the CORSIM model was in good agreement with the observed data. satisfying the purpose of this study.

Purpose: The purpose was to investigate the factors influencing alcohol consuming behavior of the female university students to provide the basic data for a nursing intervention program to improve health and prohibit of alcohol consuming behavior. Method: The subjects were 134 female university students, studying at K university and K educational university in Chungnam province from April 1 to 20, 2002. The instruments were the alcohol consuming behavior scale, that is drinking intensity score, and alcohol problem developed by Shin(1998), refusal self-efficacy scale by Aas et. al.(1995), alcohol expectancy by Goldman at. al.(1989), TPQ scale by Cloninger(1991), depression scale modified by Shin(1977) using Zung(1965)' tool, family cohesion scale by Olson at. al.(1983). The data were analyzed using descriptive statistics, Pearson correlation coefficient, canonical correlation and stepwise multiple regression. Result: The most powerful predictor of alcohol consuming behavior was influence of friends-drinking(21.0％). A combination of economic status(8.0％), and personality of novelty seeking(3.0％), accounted for 32.0％ of the variance in alcohol consuming behavior. Conclusion: I recommended that economic status, influence of friends drinking frequently, and personality of novelty seeking were contained of the developing nursing intervention program for decreasing the alcohol consuming behavior in female university students.

This study was to investigate the relationship of job stress, health status, and health promotion behavior, retention intention and to identify the influencing factors on retention intention of nurse in Emergency Room(ER). The subjects were 155 ER nurses working at 15 general hospital in Gwangju, Korea. The data were collected from October 15, 2020 to November 3, 2020. The result, there were negative correlation between job stress and health promotion behavior(r=-0.310, p=<.000), between job stress and retention intention(r=-0.220, p=.006), between health status, and health promotion behavior(r=-0.448, p=<.000), between health status and retention intention(r=-0.296, p=<.000), but there were positive correlation between job stress and health status(r=0.368, p=<.000), between health promotion behavior and retention intention(r=0.229, p=.004). Factors influencing retention intention were fatige and health status with R2 value 22.7%. Considering these results, it seems that important factors determining the retention intention of nurses in ER are Spiritual health status, heavy workload due to job stress, fatigue and social health status by nurse. Therefore, in order to increase the retention intention of nurse in ER, it is a need for strategies to improve the working environment and develop programs to reduce job stress and fatigue through work adjustment, and to maintain and promote health.

It is very important for ability to be treated to protect and secure the loss of life and property in emergency situation at sea. 80% of maritime casualty are incurred by human factors rather than a mechanical reason, which means that most maritime incident does not come from only one factor by mistake, but multiple potential factors causing a fault and error. Therefore, after research of the leadership effect to the ship, decision making process and behavior characteristics occurred in emergency situation, this paper presents settlement scheme and strategy in order to reduce human error in the ship.

In order to mitigate the damage caused by accidents in nuclear power plants (NPPs), evacuation strategies are usually managed on the basis of off-site effects such as the diffusion of radioactive materials and evacuee traffic simulations. However, the interactive behavior between evacuees and the accident environment has a significant effect on the consequential gap. Agent-based modeling (ABM) is a method that can control and observe such interactions by establishing agents (i.e., the evacuees) and patches (i.e., the accident environments). In this paper, a radiological emergency evacuation model is constructed to realistically check the effectiveness of an evacuation strategy using NetLogo, an ABM toolbox. Geographic layers such as radiation sources, roads, buildings, and shelters were downloaded from an official geographic information system (GIS) of Korea, and were modified into respective patches. The dispersion model adopted from the puff equation was also modified to fit the patches on the geographic layer. The evacuees were defined as vehicle agents and a traffic model was implemented by combining the shortest path search (determined by an A ^* algorithm) and a traffic flow model incorporated in the Nagel-Schreckenberg cellular automata model. To evaluate the radiological harm to the evacuees due to the spread of radioactive materials, a simple exposure model was established to calculate the overlap fraction between the agents and the dispersion patches. This paper aims to demonstrate that the potential of ABM can handle disaster evacuation strategies more realistically than previous approaches.

Purpose: This study was performed to examine predictors of allied health science students' exercise behavior using Pender's Health Promotion Model. Method: The subjects were 203 university students majoring in nursing, emergency medical service, and exercise prescription. The hypothetical model was based on the HPM(Pender, 1996). Exogenous variables of the model were exercise habit and role belief. Endogenous variables were exercise-related affect, exercise self-efficacy, exercise barrier, exercise intention, and exercise behavior. The data were analyzed by SAS PC program and LISREL 8.12 program. Result: The degree of exercise behavior was low(mean 1.86, range 1~4). The overall fit of the model to the data was acceptable. Exercise habit, exercise self-efficacy and exercise-related affect were significant predictors of exercise intention and exercise behavior. Conclusion: This study shows the necessity of the program to increase the level of exercise participation of university students majoring in allied health science. The model constructed in this study is applicable to explain exercise behavior of university students majoring in allied health science, and suggests that we should focus on exercise habit, exercise self-efficacy and exercise-related affect to increase the level of exercise behavior of this group.

In the existing method for analyzing the liquid tightness of the outer concrete tank in an emergency LNG spillage, the temperature variation over time inside the tank, and the concrete properties dependent on temperature and internal moisture content, have not been taken into account. In this study, the analyses for a typical LNG concrete tank subjected to thermal load due to spillage were performed with three different cases: the existing method was adopted in the first case, the transient temperature variation was considered in the second, and the temperature-moisture content dependent concrete properties were taken into account as well as the transient states of temperature in the third. The analysis results for deformation, compressive zone size, cracking, and stress of reinforcements were compared, and a discussion on the difference between the results obtained from the different analysis cases was made.
