Factors affecting cognitive function according to gender in community-dwelling elderly individuals
Miwon Kim,Jeong-Mo Park 한국역학회 2017 Epidemiology and Health Vol.39 No.-
OBJECTIVES: This study aimed to identify the factors affecting the cognitive function of elderly people in a community by gender. METHODS: We obtained 4,878 secondary data of people aged ≥65 years in 2016 at a dementia prevention center in Gyeyang-gu, Incheon. Data were obtained through Mini-Mental Status Examination optimized for screening dementia and a questionnaire. The data were statistically analyzed using analysis of variance, analysis of covariance, and hierarchical regression. RESULTS: There were significant differences in cognitive function according to gender, and the differences were significant even when age was controlled, but gender differences disappeared when education was controlled. Age, education, social activities, number of comorbid diseases, and alcohol drinking affected cognitive function through interaction with gender, but interaction with gender disappeared when education was controlled. Regression analysis showed that depression, cohabitant, social activities etc., had a significant impact on both men and women under controlled education and age. In men, the effect of social activities was greater than that of women, and hyperlipidemia had the effect only in women. CONCLUSIONS: The differences in gender-related cognitive functions were due to differences in gender education period. The period of education is considered to have a great influence on cognitive function in relation to the economic level, occupation, and social activity.
비대면 시대의 K대학 원격수업 인식 및 만족도 조사 연구
조미원 ( Miwon Jo ),김지영 ( Jiyoung Kim ) 사단법인 아시아문화학술원 2021 인문사회 21 Vol.12 No.2
본 연구는 코로나19 상황에서 실시된 대학생의 원격수업 인식 및 만족도, 만족도에 영향을 미치는 수업 인식 요인, 원격수업 운영 전반에 관한 인식을 살펴보는 데 목적이 있다. 이를 위해 경상남도 K대학교의 원격수업에 참여한 학생 1,614명을 대상으로 온라인 설문을 실시하였고 SPSS 25.0을 활용하여 일원변량분석, 단계적 회귀분석, 빈도분석을 실시하였다. 연구 결과는 다음과 같다. 첫째, 학습자들은 원격수업에 비교적 적극적으로 참여하였고 원격수업 만족도는 보통 이상으로 나타났다. 둘째, 원격수업 만족도에 영향을 미치는 수업 인식 요인은 수업 진행 속도, 교수의 열정적이고 성실한 수업 운영 등으로 나타났다. 셋째, 학습자의 선호 원격수업 방법은 교수자 얼굴이 포함 안 된 동영상 콘텐츠 수업, 원격수업의 장점은 반복 수강 가능, 단점은 수업 집중 어려움, 개선점은 강의 영상 질 개선으로 나타났다. 본 연구는 원격수업 만족도 향상 및 개선 방향의 기초자료로 활용할 수 있음에 의의가 있다. The purpose of this study is to examine the perception and the satisfaction of non-face-to-face online classes due to Covid-19. The survey was administered to 1,614 students from K University in Gyeongnam Province. Frequency analysis, one-way ANOVA, and stepwise regression analyses were conducted using the SPSS 25.0 program. The results of this study are as follows: 1) Students participated in the classes relatively actively, and the class satisfaction was above average. 2) As for the class perception factors, the speed of class progress and the sincere, enthusiastic class management were found to have positively influenced the students. 3) The class methods preferred were video content only classes without instructor faces. The advantage of the class is to rewatch class videos; students had difficulty concentrating on the classes, and the quality of the videos requires improvement. This study is significant in that it can serve as a basic data set for increasing the student satisfaction and improving online classes.
Protective Effect of Taurine on Indomethacin-induced Gastric Mucosal Injury
Son, Miwon,Kim, Hee-Kee,Kim, Won-Bae,Yang, Junnick,Kim, Byong-Kak The Pharmaceutical Society of Korea 1996 Archives of Pharmacal Research Vol.19 No.2
It has been suggested that oxygen-derived free radicals play an important role in the pathophysiology of acute gastric ulceration induced by NSAIDs and ischemia-reperfusion. Taurine is hypothetized to exert its protective effect on NSAIDs-induced gastric injury by its antioxidant properties. Protective effect of taurine on indomethacin-induced gastric mucosal lesion and its protection mechanism were investigated. Intragastric administration of 25 mg/kg of indomethacin induced hemorrhagic lesions on the glandular stomach in rats. Pretreatment with 0.25 or 0.5 g/kg of taurine one day before or for 3 days significantly reduced the gastric lesion formation and inhibited the elevation of lipid peroxide level in gastric mucosa. The luminol-dependent chemiluminescence of rat peritoneal neutrophils increased immediately after treatment of FMLP or indomethacin. Taurine (5-20 mM) inhibited chemiluminescence of neutrophils activated by FMLP. Human neutrophils (polymorphonuclear leukocytes) significantly adhered to the confluent monolayer of human umbilical vein endothelial cells (HUVEC) after coincubation with indomethacin. This neutrophil adhesion induced by indomethacin to HUVEC was prevented by taurine in a dose-dependent manner. These results indicate that the protective effect of taurine against NSAIDs-induced gastric mucosal injury is due to its antioxidant effect, which inhibits lipid peroxidation and neutrophil activation.
