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.

정영희,Jung Hyun Kwon,김지현,Youngshin Han,Sang-Il Lee,안강모 대한의학회 2012 Journal of Korean medical science Vol.27 No.7

The aim of this study was to analyze the natural history of atopic dermatitis (AD) and the risk factors associated with the remission of AD in Korean children. We enrolled 597children with AD that occurred in the first year of life. A variety of factors influencing the prognosis were assessed by medical records and telephone interviews. Their outcome was classified into complete remission, intermittent, and persistent AD. AD had completely disappeared in 422 cases (70.6%), while 149 (25%) and 26 cases (4.4%) showed intermittent and persistent skin symptoms, respectively. The average healing time was 29.6 months in complete remission group and expected healing time of the AD was 60 months. None of risk factors were significant by multivariate analysis. But, in moderate-to-severe AD group, maternal diet restriction during lactation (P = 0.046) and no sensitization to cow’s milk (P = 0.017) were significantly associated with remission of AD in the multivariate analysis. In conclusion, AD occurring in the first year of life disappears in a significant proportion of patients. In addition, in Korean children with moderate-to-severe AD, maternal diet restriction of allergenic food during lactation and sensitization to cow’s milk seem to predict the prognosis of AD.

정영희,모혜원,정지숙,최경호,최재갑,허윤경,이상흔,Jung, Young-Hee,Mo, Hye-Won,Jeong, Ji-Suk,Choi, Kyung-Ho,Choi, Jae-Kap,Hur, Yun-Kyung,Lee, Sang-Heun 대한안면통증구강내과학회 2009 Journal of Oral Medicine and Pain Vol.34 No.1

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 purpose of this study is to explore the work-family balance experience of female middle managers in the IT field. To this end, in-depth interviews were conducted with six female middle managers in the IT field, and data collected based on the analysis and phenomenological analysis method (IPA) were analyzed. As a result, 4 topics and 14 sub-themes were derived. The four topics were ‘work-family high-skilled managers in transitional IT environments’, ‘pressure due to irreplaceable IT work characteristics’, ‘work-family balance managers beyond IT work management’, and ‘new identity as female middle managers in IT field’. The results of this study provided basic data to understand the work-family balance experience and meaning of female middle managers in the IT field, and through this, discussions and suggestions were made to help develop practical psychological help and leadership.

This study aims to educate children of five years age in the thinking enhancement educational program and examine its effectiveness on the self-leadership and self-esteem of children. To achieve this goal, we can ask a question as follows: 1. What about the effect of children thinking enhancement program on the children self-leadership? 2. What about the effect of children thinking enhancement program on the children self-esteem? This study examined a total of 79 children of five years in Korean age: 38 subjects at experimental group, and 41 subjects at control group at two kindergartens located in Gwangju city. For the experimental group of kindergartener, the thinking enhancement program was applied 16 times during a period of 16 weeks. To look at the experimental examination sheet designed to measure children's self-leadership, reliability, validity, and questions of good was .928 and, to look at the sheet designed to measure self-esteem, reliability was Cronbach's α .802. For data analysis, independent sample t test and correlation was performed.
