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.
췌장암 세포에서 치자나무 열매의 세포주기 정지 및 활성 성분의 세포증식억제

GJF 처리된 PANC-1 인간 췌장암 세포의 증식이 농도의존적으로 억제되었고, 이는 GJF에 의한 세포주기 S기에서의 세포 축적으로 인한 세포주기 정지 유도 및 세포주기 조절단백질의 과도한 발현 저해 활성과 관련이 있음을 확인하였다. 또한 GJF의 함유 성분인 geniposide 및 4,5-dicaffeoylquinic acid가 췌장암 세포에 대해서 GJF와 유사한 증식억제활성을 나타내었다. 이와 같이, GJF의 췌장암 세포주기 제어 및 증식억제결과와 그 활성성분으로 geniposide 및 폴리페놀인 4,5-dicaffeoylquinic acid를 제시함으로써 GJF의 항암 활성에 대한 기초자료로 활용될 수 있을 것으로 생각된다. The ethyl acetate fraction of Gardenia jasminoides fruit (GJF) showed S-phase arrest of cell cycle in pancreatic cancer PANC-1 cells. GJF also reduced the levels of cell cycle regulatory proteins, such as cyclin B1, cyclin D1, and FoxM1, in PANC-1 cells and suppressed cell viability. Furthermore, the cell viability of PANC-1 cells was reduced by geniposide and 4,5-dicaffeoylquinic acid, which were detected in GJF by HPLC analysis. These results suggested that GJF has anti-proliferative activity via cell cycle arrest and regulation of cell cycle-related proteins in PANC-1 pancreatic cancer cells, and these effects of GJF might be partially attributed to geniposide and 4,5-dicaffeoylquinic acid.

This study examined the mediating effect of self-esteem in the relationship between maternal rejective parenting attitude and children’s leadership as well as identified gender differences in the mediating pathways. The mediating effects of this study were examined after controlling the effect of maternal employment status on rejection parenting attitude and the effect of siblings on the children’s leadership. Participants consisted of 330 five- and six-year-old children (151 boys and 179 girls) and their mothers. Data analyses included t -tests, F tests, Scheffe post-hoc tests and Pearson’s correlation. Structure equation modeling examined the mediating effect of self-esteem. Bootstrapping method was applied to examine the significance of the mediating effects. Gender differences in the mediating effect were examined through multiple group path analyses. The results of this study were as follows. First, self-esteem mediated the relationship between the maternal rejective parenting attitude on children’s leadership. Second, there was a significant gender difference in the mediating pathways with a full mediating effect of self-esteem for boys; however, there was only a partial mediating effect for the girls. This study has implication for investigating gender difference in the mediating mechanism of explaining variance in the leadership of preschoolers. The limitations and more implications of this study are also discussed.
