Emergency and evacuation planning is critical to reduce potential loss of life from flooding. In order to develop evacuation plans, emergency managers and decision makers require estimates of probable inundation areas and times of inundation. In this paper, we present an agent-based modeling approach that incorporates in a hydrodynamic model to estimate both of these properties. A case study is conducted modeling the failure of a dam located in Andong, South Korea. We estimate flood travel times for Manning's roughness coefficients and discharge using a coupling of the continuity equation and Manning's equation. Using the output from the hydrodynamic model and the flood travel times, the agent-based model produces flood inundation maps at each time interval. The model estimates that for two-thirds of the Andong region the time of inundation is estimated to be slightly less than three minutes. The results of this study can be used to in the development of emergency and evacuation planning for the region.

The purpose of this study was to analyze the characteristics of violent experiences, the types of responses to violent experiences, the coping methods among nurses working in long-term care hospitals. Data were collected using structured questionnaires from 226 nurses in 12 long-term care hospitals in J province. Data collection was performed between April 15, 2016 and April 29, 2016. The data were analyzed by using descriptive statistics and ${\chi}2-test$. Of all the respondents, 55.8% had experienced violence in the past 1 year. Of the perpetrators of the violence, 54.6% and 60.0%, were aged 65 and over and had cognitive functional decline, respectively. The most frequent type of violence was verbal abuse(90.5%). Following the violent experiences, emotional responses had the highest score($2.8{\pm}0.8$). The major coping behavior was "told their peers(84.1%)", followed by "disregarded it and worked although it felt bad(75.4%)". These results indicate the need to establish systems for violence prevention and coping, as well as applicable educational programs, tailored to the circumstances of long-term care hospitals and the characteristics of their patients.

As electronic commerce systems have been widely used, the necessity of adaptive e-commerce agent systems has been increased. These kinds of agents can monitor customer's purchasing behaviors, clutter them in similar categories, and induce customer's preference from each category. In order to implement our adaptive e-commerce agent system, we focus on following 3 components-the monitor agent which can monitor customer's browsing/purchasing data and abstract them, the conceptual cluster agent which cluster customer's abstract data, and the customer profile agent which generate profile from cluster, In order to infer more accurate customer's preference, we propose a 2 layered structure consisting of conceptual cluster and inductive profile generator. Many systems have been suffered from errors in deriving user profiles by using a single structure. However, our proposed 2 layered structure enables us to improve the qualify of user profile by clustering user purchasing behavior in advance. This approach enables us to build more user adaptive e-commerce system according to user purchasing behavior.

Purpose: The purpose of this study was to compare self-care behavior, diabetes-related stress and stress coping style among 3 blood glucose control groups (good, inadequate, and poor blood glucose control groups). Methods: Participants were 102 type 2 diabetic patients (good group: 41, inadequate group: 31, poor group: 30). Data were collected from Feb 19 to Mar 24, 2010 and were analyzed using Chi-square, Fisher's exact test and ANCOVA with SPSS/WIN 12.0. Results: Using ANCOVA with frequency of admission, and illness duration as covariates, significant differences were found among the 3 groups in self-care behavior (total score) and the exercise subscale. Using ANCOVA significant differences were found among 3 groups in diabetes-related stress (total score), emotional burden subscale and regimen distress subscale. Using ANCOVA no difference in stress coping was found among the 3 groups, but there was a significant difference in the problem-oriented coping subscale. Conclusions: Self-care behavior, diabetes-related stress, and stress coping style are factors influencing blood glucose control. The results of this study suggest that for improving blood glucose control, self care education program focused on diet and exercise in addition to stress management program for promoting problem oriented coping capability are recommended.

Purpose: This study was conducted to identify the personality type, problematic drinking pattern, and stress coping style of the nasal bone fracture patients by comparing those with general fracture patients. Methods: 50 nasal bone fracture patients due to violence and 50 general fracture patients due to simple trauma, such as fall and traffic accident were conveniently selected. Results: The study results showed that nasal bone fracture patients due to violence significantly presented higher level of A type personality and more problematic drinking pattern than general fracture patients due to simple trauma. Stress coping style, however, did not show significant difference between two groups. Conclusion: In order to prepare prevention strategies for basal bone fracture in the future, health education alter problematic drinking habit to sound drinking pattern may be offered and provided nursing interventions tailored to A type personality.

Purpose: This study was to evaluate the effects of a smoking prevention program among preschool children. Method: This study used a nonequivalent control group pretest-posttest design. The participants were 141 preschool children aged 6 or 7 at two childcare centers in Jecheon City, who were divided into an experimental group (n=66) and a control group (n=75). The smoking prevention program was applied through 9 sessions and 30 minutes per session. Surveys were conducted before and after the smoking prevention program to examine the preschoolers' knowledge and attitude toward smoking and smoking coping behavior. Results: There were significant differences between the experimental group and the control group in smoking knowledge (t=-2.02, p=.044) and smoking coping behavior (t=-2.01 p=.047), but smoking attitude (t=-1.20, p=.230) was not statistically significantly different between the two groups. Conclusion: As a result, further research is needed into the long term effects of a smoking prevention program on the future behavior of preschoolers so that the health benefits of early prevention can be quantified. It is necessary for parents to participate actively in influencing preschoolers' attitudes and behaviors with regard to the avoidance of smoking.

Purpose: The purpose of this study was to investigate the effectiveness of the coping and self-care behaviors between the individual and group education using the structured programs for the patients in chemotherapy. Methods: The quasi experimental study was designed for this study, and 30 patients received individual education and 30 patients received group education. Collecting data had been done through the seven months from March to Oct. 2011. Results: Hypothesis 1: "There could be differences in aspects of coping between the two groups educated using a structured education program" was rejected (F=2.71, p=.105). Hypothesis 2: "The individually educated group using the structured education program will have higher scores than the group education in self-care behaviors" was supported because there were statistically significant differences (F=4.16, p=.046). Conclusion: It was confirmed that individual education programs, among the patient education for cancer patients can be adopted as nursing intervention in nursing practice to improve self-care behaviors. However, there were no differences between th two group in the aspects of coping.

현대는 인터넷과 컴퓨터 없이는 잠시도 운용될 수 없는 사회이지만 이를 불법적으로 이용한 범죄행위도 점차 증가하고 있다. 이들 컴퓨터 범죄는 익명성에 기반한 대담성을 보이고 있으며, 개인의 사회적 존재로써의 자각에 있어서도 탈개인화됨에 따라 더 많은 우려를 낳고 있다. 이에 따라 일반 컴퓨터 사용자들의 프라이버시 보호를 위한 방법으로 암호화 방법을 점점 더 많이 사용하고 있는데, 이에 비례해 범죄자들의 암호사용도 증가하고 있다. 그렇다면, 범죄자들이 암호를 사용해 자신들의 범죄증거를 숨기고 있는 경우, 이를 수사하기 위해 공권력 및 수사기관은 어떻게 해야 될 것인가\ulcorner 본 논문은 이러한 문제제기를 통해 새로운 환경에 의해 변화된 코드를 활용하는 새로운 법제도를 통한 적극적인 대비방안을 모색해 보고자 한다. KLS와 같은 신기술을 수사기관 및 법집행기관이 신중하게 사용하여 국가의 법 집행력과 프라이버시권이라는 두 가지 근본 가치의 균형을 이룰 수 있는 방안을 고려하여야 할 것이다. PRIVACY와 SECURITY라는 동전의 양면은 현실생활의 법제도를 그대로 옮겨놓는 것만으로는 한계가 있다. 현재 암호와 관련한 보든 논의는 공론화 되지 못하고있다. 좀 더 공개적으로 암호를 사용한 범죄 행위에 대한 현황과 또 이를 대처한 수사기관의 수사 활동에 대해 논의하고, 그 과정에서 어떤 문제점들이 발생되고 있으며, 이들 문제를 해결하기 위해 필요한 조치들이 무엇인지에 대해 논의하고, 해외 각 국은 이 문제를 해결하기 위해 어떠한 노력들을 기울이고 있는지 살펴본후 종합적인 안목으로 시의 적절한 대책을 세우는 시발점이 되었으면 한다.

This study was conducted to investigate the relationships between job stress, stress coping strategies, empathy ability, and burnout in social workers at long-term care facilities. Data was collected from 201 social workers in three cities from March to May 2020 using structured questionnaires. Data was analyzed by descriptive statistics, t-test, ANOVA, Pearson correlations, and hierarchical multiple regression. Results showed that burnout significantly differed according to age, marital status, and career among the general characteristics. In the relationships between major variables, burnout showed a significant positive correlation with job stress and showed significant negative correlations with stress coping strategies and empathy ability. The major factors affecting burnout were job stress and empathy ability, which explained 72.3% of the variance. The results of this study suggest that job stress and empathy ability are important factors for burnout. Findings indicate a need to decrease job stress and increase empathy ability to prevent the burnout of social workers. Further studies are needed to examine burnout prevention strategies for social workers.
