Cardiovascular disease is one of the most common cause of death in postmenopausal women. After the onset of menopause, the risk of cardiovascular disease is increased. Several risk factors of cardiovascular disease are well known to us. Among the risk factors, the changes of lipid profiles are roles for cardiovascular disease. Estrogen appears to protect the development of cardiovascular disease, by several mechanism. Especially the protective effect is believed to be mediated by the changes of lipid profiles. Decreased high-density lipoprotein (HDL)-cholesterol and increased low density lipoprotein (LDL)-cholesterol are important factors for development of cardiovascular disease. The purpose of this study was to evaluate the effect of hormone replacement therapy on the lipid profiles to include total cholesterol (TC), high density lipoprotein(HDL)-cholesterol, low density lipoprotein(LDL)-cholesterol, and triglycerides. We measured lipid profiles in 31 postmenopausal women and gave each conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 5mg, day 1-12) for 12months. The levels of serum TC, LDL-cholesterol, and triglycerides were decreased significantly (p<0.05) and HDL-cholesterol was increased significantly (p<0.05) after 12months of hormone replacement therapy. These data suggest that hormone replacement therapy appears to protect agianst the development of cardiovascular disease by the changes of lipid profiles.

A carcinoid tumor of the stomach is uncommon, has no clinical symptoms, and is regarded as a benign. It is also incidentally found in most cases. 48-year-old woman with gastric carcinoid tumor was admitted. She had suffered from a anorexia and a dry mouth for 4-months. A gastroscopy revealed a polypoid mass on the greater curvature of the mid-body of the stomach which was subsequently thought to be an adenocarcinoma. An endoscopic mucosectomy revealed however, that it was a carcinoid tumor. A case of carcinoid tumor of the stomach is here by presented with a brief literature review.

An Analysis of the Relationship between Sports Center Users' Participation in Physical Activity, Leisure Boredom and Leisure Satisfaction The purpose of this study is to research and analyze the relationship between sports center users' participation in physical activity, leisure boredom and leisure satisfaction. To be more specific, this study examined the effect of level of participation in physical activity - participation frequency, participation intensity and participation duration - on leisure boredom and leisure satisfaction. I used simple random sampling to pick out 312 physical program participants from a population composed of five sports centers in Seoul, Korea in 2003. It is conducted using the Questionnaire on the Relationship between Sports Center Users Participation in Physical Activity, Leisure Boredom and Leisure Satisfaction. The Cronbach's α method gave a subordinate factor-based reliability coefficient of α = .6921 for leisure boredom and α = .9385 (highly reliable) for leisure satisfaction, respectively. The methods for data analysis used for this study include frequency analysis, correlation analysis and regression analysis. Study findings are as follows: 1) As for the participation frequency relating to the level of participation, the effect have a positive correlation with participation intensity(r=.162*), participation duration(r=.147*) and leisure satisfaction(r=.275*) while the effect on participation intensity have a positive correlation with leisure satisfaction(r=.151*). 2) A statistically insignificant difference (5% range) was identified regarding all subordinate factors (i.e., participation frequency(β=.093), participation intensity (β=.075), participation duration(β=.032) 3) A statistically significant difference (5% range) was identified regarding all subordinate factors (i.e., participation frequency(β=.231), participation duration(β=.185)) while a statistically insignificant difference was identified for participation intensity(β=.107). Participation frequency and participation duration have a positive correlation of 12.3%(R²=.123) with leisure satisfaction.

본 연구는 2004년 1월부터 2008년 10월까지 원광대학교 병원 피부과에 내원한 원형 탈모증 환자 126명중 치료 결과를 확인 할 수 있었던 95명을 대상으로 인구학적 특성 및 치료 방법에 따른 치료 효과의 차이를 알아보고자 빈도 분석 및 교차분석을 통하여 유의성을 검정하였다. 탈모반면적은 성별에서 남자와 여자가 각각 26-50%일 때 53.5%, 71.4%로 가장 많았으나 유의한 차이는 없었고, 연령별로는 20대 이하와 30대, 40대 이상이 각각 26-50%일 때 54.1%, 51.9%, 58.6%로 가장 많았으나 유의한 차이는 없었다. 치료방법은 성별에서 남자와 여자 각각 부신피질호르몬 국소방법을 94.3%, 85.7%로 가장 많았으나 유의한 차이는 없었고, 연령별로는 20대 이하, 30대, 40대 이상이 각각 스테로이드 국소 주사요법을 89.7%, 100%, 93.1%로 가장 많았으나 유의한 차이는 없었다. 치료효과는 성별에서 남자와 여자 각각 완치하였다가 64.8%, 71.4%로 가장 많았으나 유의한 차이가 없었고, 연령별로는 20대 이하와 30대의 경우 완치되는 경우가 각각 71.8%, 85.2%로 가장 많았고, 40대 이상은 부분반응 하는 경우가 58.6%로 가장 많았으며 통계적으로 유의한 차이를 보였다(p<0.05) 치료방법에 따른 치료효과에는 유의한 차이가 있었다(p=0.003). 스테로이드 pulse therapy를 사용한 경우 완치가 100%, DPCP 요법은 완치가 77.8%, minoxidil 국소요법은 완치가 73.8%, 스테로이드 pulse therapy의 경우 완치가 100%로 가장 많았다. Background: We embarked on this research in order to gain fundamental information and knowledge on the key differences in the effectiveness of various treatments and factors, such as key clinical conditions and demographic traits through the descriptive research-based procedures, on patients with alopecia areata. Methods: Based on the comprehensive data of 95 patients with verifiable treatment records out of 126 alopecia areata patients who have visited the department of dermatology of Wonkwang University Hospital from January 2004 to October 2008, We examined the significance tests through the analysis of frequency and range of the differences in the effectiveness of various treatments using demographic traits and medical treatments. Results: In terms of the treatment effectiveness, 64.8% of the male patients and 71.4% of the female patients showed the full recovery, with virtually no significant clinical data difference. In terms of the age group variations, 71.8% of the patients in 20's and under and 85.2% of the patients in 30's showed the full recovery, and 58.6% of 40's showed only partial recovery, rendering this difference quite significant.(p<0.05). There was a noticeable difference in effectiveness of various treatments.(p<0.01). Through the steroid pulse therapy, 100% of the patients fully recovered, 77.8% through the DPCP(Diphencyprone) method, 73.8% through the minoxidil application treatment, 65.2% through the steroid injection treatment, and finally 33.3% of the steroid application treatment fully recovering from the hair loss. Conclusion: In terms of the effectiveness, the steroid pulse therapy were most dominant and clear treatment, followed by DPCP treatment, the minoxidil application treatment, the steroid injection treatment, and the steroid application treatment in this order. In terms of the distribution of the gender factor of the observed patients, the number of female patients was far smaller than that of male patients, and tremendous barriers and challenges lie in the quest to make a conclusive finding through the use of the raw data of hospital patients. As such, a variety of rigorous and dynamic clinical research endeavors and the large sample of patients are necessary and strongly recommended at this point.

黑心可鍛鑄鐵의 燒鈍에 依한 黑鉛化의 生成에 關한 硏究

The previous report stated that the direct graphitizing process without decomposition of pearlite could be practised experimentally in malleable cast iron annealing, that is, by holding the iron for about sixtyhours. After cooling transformation begins, a fully ferritized malleable cast iron is obtained. It has also been clarified that it is rather difficult to keep the castings in such narrow temperature range as 730 to 740℃ under foundry conditions. With the view of investigating the resolution vehavior of pearlite remaining after direct graphitiaztion into austenitic matrix, specimens haveing bull's eye structure or pearlite were quenched after holding for various periods at predetermined temperatures and their microstructures were examined. The results obtained are summarized as follows: 1) The existence of a trace of cementite after resolution of pearlite into austenitic matrix when the specimen is reheated above critical temperatues accelerates the precipitation and growth of pearlite depending upon the volume and number of remaining pearlitic cementite during slow cooling through the critical range. In other words, a trace of cementite retards the direct graphitization in the critical range. 2) As lamellar pearlite precipitated during cooling deccomposes extremely slowly at subcritical temperatures, it is important to prevent the formation of pearlite during cooling in order to have the direct graphitization completed during slwo cooling in the appropriate temperature range. 3) It is necessary to hold the iron for at least 1hr. at 900℃ to dissolve the pearlitic cementite into austenite. 4) It was found by the author's experiment that a blackherat malleable iron having fully ferritized matrix can be obtained by extremely slow cooling through critical direct-graphitzing temperature range.
