In 2022, wildfires broke out in Uljin-gun and Samcheok-si, which set the record for the longest forest fire in Korea, but there were no casualties. To protect local residents from wildfires, they must evacuate. Predicting the demand for evacuation in the event of wildfires is essential for the efficiency of disaster management. The purpose of this study is to analyze the human mobility patterns according to the occurrence of Uljin-gun and Samcheok-si wildfires. SKT floating population data was used in this study to analyze the human mobility patterns in Uljin-gun and Samcheok-si. The main findings are as follows. First, while the movement of the resident and visiting population decreased, the movement of the worker population was found to be similar to normal. Second, the resident population of Buk-myeon, Uljin-gun moved to the surrounding area to avoid the wildfires. Third, the region is an area judged to be safe from wildfires, and this mobility patterns are related to emergency disaster text messages. This study confirmed human mobility patterns of the population in the area where the wildfires through the floating population data, which is quantitative data. This suggests that it is important to guide residents to shelters through emergency text messages to minimize damage in the event of wildfires.

본 연구는 유아의 개인변인에 따라 자아존중감과 정서지능 및 리더십에 차이가 있는지를 알아보고 유아의 자아존중감, 정서지능 및 리더십 간의 관계 및 유아의 자아존중감과 정서지능이 리더십에 미치 는 영향을 알아보는데 목적이 있다. 연구를 위하여 서울과 경기 및 인천지역에 위치한 12곳의 유치원과 어린이집에 재원하고 있는 만 4∼5세 유아 218명을 대상으로 설문조사를 실시하여 분석하였다. 연구결 과는 첫째, 유아의 리더십은 성별에 따라 유의한 차이가 있는 것으로 나타났으며, 성별과 출생순위에 따라 상호작용 효과가 있는 것으로 나타났다. 즉, 여아가 남아보다 리더십이 더 높았으며, 남아는 첫째 가, 여아는 둘째 이상이 리더십이 가장 높았다. 둘째, 유아의 자아존중감 및 정서지능은 리더십과 유의 한 정적 상관관계를 갖고 있는 것으로 나타났다. 즉, 유아의 자아존중감과 정서지능이 높을수록 리더십 이 높은 것으로 나타났다. 셋째, 유아의 자아존중감과 정서지능은 리더십에 유의한 영향을 주는 변인으 로 나타났다. The purpose of this study was examine the effect of young children’s self-esteem and emotional intelligence on children’s leadership. The participants of this study were 218 young children of four- to five-year-olds who were enrolled in the 12 kindergartens and child-care centers at Seoul, Inchoen, and Gyeonggi area. The results of this study were as follows. First, young children’s leadership showed significant differences by gender. Also, the interaction effect by gender and birth order of children was found in children’s leadership. It means that girls had higher leadership scores than boys; moreover, the first-born boys and second-born or more girls had the highest leadership score. Secondly, there were positive relationships among children’s leadership, self-esteem and emotional intelligence. Finally, young children’s self-esteem and emotional intelligence were the significant predictors of young children’s leadership. Positive self-esteem was the strongest predictor for children’s leadership.

In the small household appliances system, in an efficient and hygienic to use of a lot of pressure vessel of plastic material. It is necessary to reflect on the design in order to produce a stable structure, and reduce the failure by predicting a weak position before producing the pre-task. Compare to typical steel, polymer material is way more ductile. Thus, it is not easy to analytically validate. In this work, the fracture ductility in accordance with the pressure of the pressure vessel fabricated by PP is a strong polymer material were studied a method of predicting. To the toughness values that can take into account the growth and the criterion of reduction in the mechanical properties. Area obtained by integrating the Stress-Strain curve due to the pressure change. It was defined as fracture toughness due to pressure. It was analyzed followed by its structural simulation with commercial structural analysis software (ANSYS) and using the breaking pressure obtained through actual experiments was applied to the analytical criteria. Polymer material through this method propose a method for predicting the fabricated parts determined analytically.

The purpose of the present study is to investigate anti-depressive effects of Samul-tanggahyangbuja (SGH) on ovariectomized and chronic mild stress (CMS) induced rats. Methods: Ovariectomized rats were exposed to CMS for 4 weeks. Changes of depression behavior were tested by using sucrose intake test (SIT), elevated plus maze (EPM), forced swimming test (FST) and Morris water maze test (MWMT) in rats until being orally medicated with SGH (100 or 400 mg/kg/day). In addition, the serum levels of corticosterone (CORT), IL-4, IL-1β and changes of 5-HT in the brain were measured. Results:1. SGH 400 mg/kg treated group (SGH 400) significantly increased amount of sucrose intake compared with the control group (p<0.05). 2. SGH 100 mg/kg treated group (SGH 100) and SGH 400 significantly increased the time spent in the open arms of the EPM compared with the control group (p<0.01). SGH 400 also significantly increased the number of crossing of the open and closed arms compared with the control group (p<0.05). 3. SGH significantly shortened the immobility time in FST compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). 4. SGH significantly increased performance of acquisition trials compared with the control group (p<0.05, on day 4, 5 of SGH 100 and 400). SGH 400 also significantly increased performance of retention trials compared with the control group (p<0.05). 5. The serum levels of corticosterone and IL-4 were not significantly different among the groups. There were no changes on the serum levels of corticosterone, IL-1β and IL-4 after administration with SGH. 6. SGH 400 significantly increased the level of 5-HT in the hippocampus compared with the control group (p<0.05). SGH significantly increased the levels of 5-HT in the hypothalamus compared with the control group (SGH 100 p<0.05, SGH 400 p<0.01). Conclusions: These results suggest that SGH has the anti-depressive effect on ovariectomized rat and affect 5-HT system rather than hypothalamic-pituitary -adrenal (HPA) axis and immune system.
