Recently there is much interest in the antibacterial activity of nano-sized silver particle (nanosilver) since silver is known to be safe and effective as disinfectant for a long time. Oral malodor is considered to originate in the oral cavity primarily as a result of production of malodorous compounds by oral bacteria. Major compounds responsible for oral malodor are volatile sulfur compounds, which is thought to be generated by the G(-) anaerobic bacteria found normally in the oral cavity, especially on the dorsum of the tongue. The purposes of this study were to investigate the effect of nanosilver on growth of oral malodor generating microorganisms, including Fusobacterium nucleatum, Prevotella melaninogenica, Klebsiella pneumonia, and to determine the optimal culture condition of them. The results were as follows: 1. The optimal culture condition for P. melaninogenica was vacuum culture using desiccator after evacuation of air by vacuum pump in chopped beef meat media. 2. The growth of K. pneumonia was temporarily inhibited by nanosilver (5 ppm and 10 ppm). 3. The morphological alteration and cell damage caused by nanosilver were observed in K. pneumonia.

The study investigated the serum lipid metabolism and enzyme activities of Korean teas for their preventative activity against chronic disease and obesity. Male Sprague-Dawley rats were raised for 8 weeks on four experimental diets: normal diet, hyperlipidemic diet, and hyperlipidemic diet to which green and black teas (2% each) were added. Various biological actions, including lipid metabolism and enzyme activities of the serum, were investigated. Diet-induced, hyperlipidemic rats fed with green and black teas, showed significant decrease in food efficiency ratio, triglyceride, total lipid, and phospholipid compared to control, i.e. the normal and diet-induced, hyperlipidemic rats. Total cholesterol, LDL-cholesterol, Al(atherogenic index), LHR, VLDL-cholesterol, ester-cholesterol, and free-cholesterol also showed a significant decrease. However, there was no significant difference between the tea-fed, diet-induced, hyperlipidemic dieted groups. HDL-cholesterol concentration was increased significantly in the tea-dieted and normal groups compared to the control. There was a little difference in lipase activity between the normal and control groups, although green and black tea-dieted experimental groups were both increased compared to the control. The contents of total lipid, triglycerides, and total cholesterol were decreased in the normal and experimental groups compared to the control. The GOT, GPT, ALP and LDH serum enzyme activities of the experimental groups were significantly reduced compared to those of the control groups.

畿湖興學會 忠南支會의 活動에 관한 硏究

鄭英熹(Jung Young Hee) 역사실학회 2001 역사와실학 Vol.19·20 No.-

The threatened national state of mind of the Japanese colonial era made the nation concentrate a lot of its efforts on education. These interests were shown through the establishment of many private educational institutions. The Gi-ho Education Revival Assembly(畿湖興學會) was a patriotic enlightenment group that was established in 1908 for the purpose of the revival of education in the region of Gi-ho. While establishing a Gi-ho school to train teachers and running a teacher introduction agency, it established a school for each county to maximize the effects of education. The members of the plenary and branch office participated in education promotion movements and national debt-compensation movements(國債報償運動). Rural county officials sponsored these institutions under the ‘Private School Order(私立學校令)’ and were the foundation that allowed the Gi-ho assembly to continue their campaigns. However the activities of the plenary and branch office had to proceed under the law approved by the Residency-General. In reality, the workers tried not to create a conflict between the rural officials and their objectives. Also, although the activities of the workers at the branch office and the activities of the plenary coincided with each other, differences existed between different regions. Seen from these points, the activities of the plenary and the branch office of trying to deter the development of the Japanese colonialization was beyond their reach, and they had difficulty accomplishing their goals. However their activities included participation in the Independence Movement on March 1st, the Night-study Movement(夜學運動), the Production Promotion Movement(物産?勵運動), and the People′s University Movement(民立大學設立運動). These participations all became the basis for the Skills Development Movement(實力養成運動).

Purpose: The aim of this study was to evaluate perception and satisfaction with Health Education for elementary school students in grade 5 and 6, using data on national health education gathered since March, 2009. Methods: Data were collected by way of a questionnaire, from 475 elementary school students in grades 5 and 6 from February 1~15, 2010. Statistical analysis of collected data was performed using frequency, t-test, Pearson"s correlation coefficient, and hierarchical multiple regression analysis, using SPSS 18.0 software. Result: Levels of health promoting behavior, interest, importance, and satisfaction were relatively high, respectively, and those of students in grade 5 were higher than those of students in grade 6. Levels of Satisfaction with frequency and educational environment were relatively low. Among the factors found to influence satisfaction with health education, interest in health education was found to be the most influential(grade 5: β=.279, p<.001, grade 6: β=.306, p<.001). Conclusion: Students expressed a high level of satisfaction with regular health education. Expansion of health education frequency and health education-only-classrooms is needed. To improve the effect of health education, constant acquisition of knowledge of subjects’ perception and satisfaction is needed. In addition, contents and teaching methods that showed low level of satisfaction should be reformed.
