The subject of this study is adolescents who are attending middle or high schools, and this study tried to figure out the effect of stress which is recognized by adolescents on the adaptation to school life. And the objective of this study is to analyze the stress factors of adolescents to reduce the frequency of the stress, and to figure out the correlation between stress of adolescents and their adaptation to school life to help them successfully adapt to school life.
To study the effect of the aconite on blood sugar level, ethanol extract of the aconite was administered intraperitoneally in two groups of the rats at doses of 250mg and 500mg per kg of body weight respectively. After 250 mg/kg of the aconite administeration the blood sugar level elevated maximally from 102.9±6.7mg% to 151.2±6.lmg%, while it maximally changed from 103.2±5.2mg% to 161.0±5.3mg% 고 500mg/kg of aconite administered group. In both groups (250mg/kg & 500mg/kg) a maximum elevation of blood glucose levels were observed at 15 minutes after aconite administration followed by rather rapid decline in 30 minutes. And no marked changes in sugar level were observed (130.5±3.5mg% &132.1±3.2 mg%) thereafter. Though the precise mechanisms of blood sugar elevation by the aconite is not certain, it is suggested that the disturbance of glucose-buffering function in the liter may be most responsible for the increased sugar level.
The purpose of this study was to survey the caries prevalence rate and risk factors of nursing caries of preschool children. The subject of study were 571 preschool children in the metropolitan area and the city area. Nursing caries was defined as the caries involving labial or lingual side of maxillary central or lateral primary incisors. The subjects' teeth were examined by two dentists with dental mirror and explorer. And their mothers were asked to write questionnaires. The risk factors were analyzed by multiple logistic regression. The results of this study were as follows. 1. Nursing caries prevalence rate of preschool children was 13.0%. 2. The probability of nursing caries experience of preschool children was higher in the metropolitan area than in the city area. 3. The probability of nursing caries experience of preschool children who were breast-fed only is higher than that of preschool children who were bottle-fed only or breast-fed and bottle-fed. 4. For nursing time, the subjects with less than 10 minutes showed lower probability of nursing caries experience than the subjects with 10 minutes or more. 5. The probability of nursing caries experience of preschool children was higher nursing time was long at night sleeping than when nursing time was short at night sleeping.
본 연구의 목적은 장애아동 부모의 여가활동 참여 정도 및 만족도가 자아존중감에 미치는 영향을 분석하고자 한다. 연구대상은 충청북도 ◌◌시의 장애아동 부모 185명을 대상으로 2015년 1월 10일부터 2015년 3월 10일까지 설문조사를 실시하였다. 분석방법은 SPSS 프로그램을 사용하여 인구사회학적 특성의 빈도분석, 신뢰도분석, 상관분석과 여가활동 참여 정도, 여가활동 만족도가 자아존중감에 미치는 영향을 알아보기 위해 다중회귀분석을 실시하였다. 연구결과 첫째, 장애아동 부모의 여가활동 참여 정도는 동적 여가활동과 정적 여가활동 모두 높을수록 자아존중감이 높은 것으로 나타났다. 둘째, 장애아동 부모의 여가활동 만족도에서 교육적, 심리적, 환경적 만족도가 높을수록 자아존중감이 높은 것으로 나타났다. 본 연구의 시사점은 장애아동 부모의 적극적인 여가활동 참여와 활성화를 통해서 여가활동 만족도를 높여 자아존중감을 향상 시킬 수 있는 여가 프로그램 개발 및 여가정책에 관한 기초자료가 될 것으로 사료된다. The purpose of this study is to analyze the effect that the level of leisure activity participation and satisfaction for the parents of disabled children has on their self-esteem. For this study, a survey was conducted on 185 parents of disabled children in ○○ city of Chungcheongbuk-do Province from January 10, 2015 to March 10, 2015. Using the SPSS program, we conducted frequency analysis, reliability analysis, correlation analysis of the sociodemographical characteristics data as well as multiple regression analysis to identify the effect that leisure participation and leisure satisfaction has on self-esteem. The results showed that, first, higher level of leisure activity participation of parents with disabled children, both for dynamic leisure and silent leisure was correlated with higher self-esteem. Second, self-esteem was high when leisure activity satisfaction of parents with disabled children was high for educational, psychological, and environmental satisfactions. This study implies that it will provide a useful preliminary data for the development of leisure programs and leisure policies to promote active leisure activity participation for parents of disabled children, which will lead to their leisure activity satisfaction and ultimately improve their self-esteem.
In 30 rats divided into salt, ethanol and salt plus ethanol groups, the effect of ethanol on the course of hypertension induction with the salt ingestion was studied. The results obtained from the present study are as follows. 1) In salt group mean arterial blood pressure elevated to plateau (about 140 mmHg) in two weeks and the increased blood pressure was well maintained throughout entire experimental period. 2) By four weeks after ethanol ingestion, mean arterial blood pressure of ethanol group was slightly decreased followed thereafter by slow restoration to control value. And it was believed that decline of blood pressure observed in this case probably was not resulted from cardiac depression. 3) As mean arterial pressure in salt plus ethanol group remained rather low compared with that of salt group, it was suggested that ethanol may have a dose reduction effect in the course of hypertension induction by excessive salt ingestion. It was, however, not possible from the result of present study to decide that low blood Pressure in this group was resulted whether from enhanced sodium excretion activity of ethanol or from effect on blood pressure of ethanol itself.
