This study is for increasing evacuation safety by analyzing RSET(the required safe escape time) through the arrangement of personnel by floor and by room while evacuating in a Girls' High School Dormitory. For this study, PAPS(Physical Activity Promotion System) results that have not been studied so far were analyzed and reflected in evacuation simulations on the premise that individual student's physical strength can affect evacuation. Based on the PAPS results, four scenarios were applied. In addition, evacuation simulation using the pathfinder program was conducted in two situations: the evacuation route was assigned or not. Scenario 4 was the fastest at 168.5 seconds of RSET in assigning evacuation routes among scenarios. As a result of this study, the arrangement of students focusing on improving their academic ability and student life guidance excluding student physical strength has problem. In order to solve this problem, it is effective to place C group students(low grade on PAPS) on low floors and A group students(high grade on PAPS) on high floors and to assign evacuation routes in each room. In the future, the following ways need to be more studied. A study on how to increase evacuation safety through practical evacuation training, the way of assessing evacuation safety reflecting the lifestyle and physical strength of girls, the evacuation route assignment according to the fire occurrence point, and the method to secure evacuation routes in the event of a fire near stairs or entrances should be conducted.

The purpose of this study is to examine the effects of social withdrawal, depression, aggression, negative parenting attitude as parental factors, friendship as school factors, academic helplessness and smartphone dependence, persistence, etc. on adolescent delinquency experiences as perceived personal factors. was carried out to understand. For this study, first year middle school students in the first year of the Korean Children and Youth Panel Survey (KCPYS 2018) were analyzed. As a result of the study, it was found that depression, aggression, social withdrawal as individual factors of adolescents, negative parenting attitude as parent factors, academic helplessness, negative friendships, smartphone dependence, persistence, etc. as school factors influence delinquent behavior of adolescents. In addition, it was found that smartphone dependence and persistence play a partial mediating role in the process of personal factors, parental factors, and school factors affecting adolescents' delinquency experiences. Based on these results, first, we need to break stereotypes about adolescents and understand the accurate understanding of adolescents' delinquent behaviors and what expectations they have. Second, practical education is required for parents and grandparents for consistent parenting attitudes and effective parenting. Third, a positive self-awareness and correct human relationship formation program should be operated in order to improve the friendship among adolescents. Finally, correct smartphone usage and counseling interventions and prevention programs to alleviate impulsivity are needed.

The purpose of this study was to examine the mediating effect of functional and dysfunctional expressions of anger on the relationship between covert narcissism and dating violence among college students. The study also investigated gender differences with regard to covert narcissism, dating violence, and functional and dysfunctional expressions of anger. To this end, 339 college students (133 males, 206 females) with heterosexual dating experiences in the Busan Metropolitan area were recruited. They responded to the Covert Narcissism Scale, the Revised Conflict Tactics Scale 2, and the Korean adaptation of the State-Trait Anger Expression Inventory. The results were as follows. First, covert narcissism, dating violence, and functional and dysfunctional expressions of anger differed significantly by gender. Second, there were statistically significant correlations between covert narcissism, dating violence, and functional and dysfunctional expressions of anger. Third, multiple regression analysis showed that dysfunctional expressions of anger for males were positively correlated with dating violence while functional expressions of anger were negatively correlated. For females, dysfunctional expressions of anger were positively correlated with dating violence while functional expressions of anger were not significantly correlated. Fourth, dysfunctional expressions of anger completely mediated the relationship between covert narcissism and dating violence for both males and females, but functional expressions of anger had no mediating effect. These results suggest that dysfunctional anger expression control program should be developed for students which may help those with covert narcissistic tendencies to functionally express their anger. Future research should analyze dating violence prevention and counseling programs.

With the recent increase in dementia patients due to aging, measures to prevent their wandering behavior and disappearance are urgently needed. To solve this problem, various authentication methods and location detection techniques have been introduced, but the security problem of personal authentication and a system that can check indoor and outdoor overall was lacking. In order to solve this problem, various authentication methods and location detection techniques have been introduced, but it was difficult to find a system that can check the security problem of personal authentication and indoor/outdoor overall. In this study, we intend to propose a system that can identify personal authentication, basic health status, and overall location indoors and outdoors by using wristband-type wearable devices in a private blockchain environment. In this system, personal authentication uses ECG, which is difficult to forge and highly personally identifiable, Bluetooth beacon that is easy to use with low power, non-contact and automatic transmission and reception indoors, and DGPS that corrects the pseudorange error of GPS satellites outdoors. It is intended to detect wandering behavior and abnormal signs by locating the patient. Through this, it is intended to contribute to the prompt response and prevention of disappearance in case of wandering behavior and abnormal symptoms of dementia patients living at home or in nursing homes.

It is essential to increase the implementation rate in order to increase the effectiveness of mitigation measures that can mitigate the negative impact of development projects. In the case of Environmental Impact Assessment (EIA),research on the implementation evaluation of development projects is insufficient, even though the effectiveness of mitigation measures has been steadily raised. Therefore, this study evaluated the implementation rate of the mitigation measures and identified the cause of the difference in the implementation rate for each mitigation measures in order to understand the current status of the ecological mitigation measures. The implementation rate of urban and road development projects mitigation measures was 56.0% and 64.4%, respectively. the implementation rate of 'Monitoring' mitigation measures was the highest in all development project. But, 'Habitat creation' and 'Accident prevention measures' were low. In addition, it was found that the implementation rate of the mitigation measures were high when the contents of the mitigation measure described in the report were specific. Through this study, it was found that in order to increase the implementation rate of the EIA ecological environment animal mitigation measures, it is necessary to reflect the environmental and geographical characteristics of the target site in detail. Furthermore, it is judged that this study can be used as a basic basis for enhancing the effectiveness of the EIA system introduced to mitigate the negative impact on the environment.

Purpose : The purpose of this study is to determine the effect of the overseas volunteer activities of university students on changes in global citizenship. Methods : This study was conducted as a one-group pre-posttest design. The study's subjects were students who participated in the 37th World Friends Korea Youth Volunteer Corps in 2018. Among them, 158 students who completed the survey were included in the analysis. The tool for measuring global citizenship was comprised of knowledge, skill, attitude, and willingness to practice. The data were analyzed using the SPSS 26.0 program, and the statistical significance was set to p<.05. Results : Among the study's participants, there were 123 females (77.85 %). By grade, there were the most juniors, with 68 (43.04 %). There were 53 (33.55 %) seniors, 28 (18.35 %) sophomores, and eight freshmen (5.06 %). Among all participants, 52.53 % had experience in global citizenship education, and 63.92 % had experience in activities related to global citizenship. Because of analyzing the changes in global citizenship before and after overseas volunteer activities, "skill" increased the most, from 3.51±.65 points to 4.34±.56 points (p< .001). Due to analyzing changes in global citizenship before and after overseas volunteerism, the knowledge and attitude of freshmen were statistically significantly positive, with 1.17± 1.23 (p=.011) and 1.41±1.22 (p=.008), respectively. Participants with global citizenship experience had a significant change in attitude (p=.018). Conclusion : It was confirmed that the overseas volunteer activities of undergraduate students in the university brought a positive change to global citizenship. Providing opportunities for global citizenship education and activities in elementary, middle, and high schools in the future will maximize the effects of overseas volunteer activities to improve global citizenship.

The purpose of this study is to examine the mediating effect of physical activity in the relationship between generalized anxiety disorder and overdependence on smartphones in adolescents. To find a way for solving the problems caused by the over-use of smartphones during adolescence, we tried to find the importance of a health promotion program through physical activities. For the purpose of the study, the 2020 Youth Health Behavior Survey data conducted by the Ministry of Education, the Ministry of Health and Welfare, and the Korea Centers for Disease Control and Prevention were used as analysis data for this study. As a result of the study, firstly, generalized anxiety disorder has a negative (-) relationship with physical activity, and physical activity also has a negative (-) relationship with overdependence on smartphones. Secondly, as a result of analyzing the mediating effect of physical activity in the relationship between generalized anxiety disorder and smartphone overdependence experience, the physical activity was found to be a significant factor. Thirdly, it was confirmed that the physical activity has a partial mediating effect in the relationship between generalized anxiety disorder and smartphone overdependence experience. Increasing physical activity through team sports rather than individual sports may help reduce smartphone use.

Purpose: Several studies have been conducted on the relationship between green tea intake and metabolic syndrome. However, compared to the studies carried out internationally, there is inadequate research on the relationship between domestic green tea consumption and metabolic syndrome. Therefore, in this study, the general characteristics of Koreans according to their green tea intake and its association with metabolic syndrome were examined. Methods: A total of 44,611 subjects were included in the study, and analysis was carried out using data from the Korean Genome and Epidemiology Study (KoGES) for Korean adults aged 40 or older. Green tea consumption was estimated using 106 verified food frequency questionnaires (FFQ). Metabolic syndrome was defined using the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) parameters. After adjusting for confounding variables by performing a Cox regression analysis, the association between green tea consumption and metabolic syndrome was confirmed through the hazard ratio (HR) and 95% confidence interval (CI). Results: The average incidence of metabolic syndrome was 18.7% (20.8% in men and 17.8% in women). Compared to those who drank almost no green tea, in subject groups consuming more than one cup of green tea a day, the metabolic syndrome incidence was significantly reduced by 15% (HR, 0.85; 95% CI, 0.74-0.96; p trend = 0.0200) among men and by 19% (HR, 0.81; 95% CI, 0.73-0.90; p trend < 0.0001) among women. In addition, the biomarkers related to metabolic syndrome also tended to decrease overall in these groups. Conclusion: This study concluded that as the intake of green tea increased, the incidence of metabolic syndrome and related indicators decreased. Therefore, green tea intake is believed to have a positive effect on the prevention and management of the metabolic syndrome.

As the number of people with chronic diseases increases due to an aging society, it is urgent to prevent and manage their diseases. Although biometric authentication methods and Telemedicine Systems have been introduced to solve these problems, it is difficult to solve the security problem of medical information and personal authentication. Since smart healthcare includes personal medical information of subjects, the security of personal information is the most important field. Therefore, in this paper, we tried to propose a Telemedicine System using a smart wearable device ECG in the form of a wristband and face personal authentication in a private blockchain environment. This system targets various medical personnel and patients with chronic diseases in all regions, and uses a private blockchain that can increase data integrity and transparency, ECG and face authentication that are difficult to forge and alter and have high personal identification to provide a system with high security and reliability. composed. Through this, it is intended to contribute to increasing the efficiency of chronic disease management by focusing on disease prevention and health management for patients with chronic diseases at home.
