양정화(Jung-Hwa Yang),한지숙(Ji-Sook Han) 한국식품영양과학회 2006 한국식품영양과학회지 Vol.35 No.5

본 연구는 상엽추출물의 섭취가 당뇨병 환자의 혈당, 당화혈색소 및 혈청지질에 미치는 영향을 조사하고, 체내 간기능에서의 안전성도 검증하기 위하여 당뇨병 환자에게 12주간 1,000 ㎎의 상엽추출물을 섭취시켜 전ㆍ후 차이를 비교하였으며 그 결과는 다음과 같다. 상엽군은 체중이 실험 전 58.6±9.2 ㎏에서 실험 후 58.8±9.1 ㎏으로 변화를 보이지 않았으며, 허리둘레 및 엉덩이 둘레도 실험 전ㆍ후 거의 변화를나타내지 않았으므로 상엽추출물의 섭취는 신체계측치에 영향을 미치지 않았다. 상엽군에서 수축기 혈압은 127.1±18.9 ㎜Hg에서 128.7±21.0 ㎜Hg로, 이완기 혈압은 80.5±12.1 ㎜Hg에서 77.0±12.1 ㎜Hg로 거의 변화를 나타내지 않음으로서 상엽추출물의 섭취는 당뇨병 환자의 혈압에 영향을 미치지 않았다. 상엽군에서 공복혈당은 141.9±39.4 ㎎/㎗에서 135.8±41.4 ㎎/㎗로, 당화혈색소는 7.8±1.4%에서 7.0±0.6%로 유의(p<0.05)하게 감소하였다. 그러나 위약군에서는 실험 전ㆍ후 공복혈당 및 당화혈색소에서 차이를 나타내지 않았다. 상엽추출물의 섭취가 12주간 이루어지면서 총콜레스테롤은 188.4±21.9 ㎎/㎗에서 176.7±23.8 ㎎/㎗로 감소하였고, LDL-콜레스테롤에서는 상엽군은 116.9±29.3 ㎎/㎗에서 104.3±23.2 ㎎/㎗로 유의(p<0.05)하게 감소한 반면, 위약군은 121.3±24.3 ㎎/㎗에서 121.5±17.3 ㎎/㎗로 변화가 없었다. 중성지방은 상엽추출물의 섭취 후 167.6±44.5 ㎎/㎗에서 123.2±29.3 ㎎/㎗로 유의(p<0.01)하게 감소한데 반해 위약군은 152.0±55.9 ㎎/㎗에서 155.3±51.4 ㎎/㎗로 오히려 약간의 증가를 보였다. 상엽섭취군의 공복혈당 및 당화혈색소 농도수준에 따라 그 변화를 살펴보면, 공복혈당 불량군은 실험 전 188.2±45.2 ㎎/㎗에서 상엽추출물 섭취 후 161.3±25.3 ㎎/㎗로 유의(p<0.05)하게 감소한 반면 공복혈당 양호군에서는 119.3±22.4㎎/㎗에서 119.9±21.9 ㎎/㎗로 변화를 보이지 않았다. 당화혈색소 불량군의 경우 실험 전 8.7±0.7%에서 실험 후 7.8±0.8%로 유의(p<0.05)하게 감소한 것에 반하여, 당화혈색소 양호군에서는 6.7±1.2%에서 6.6±1.2%로 변화가 없음을 확인할 수 있었다. 상엽추출물의 12주간 섭취 후 AST는 24.8±3.5 IU/ℓ에서 31.8±8.7 IU/ℓ로, ALT는 26.4±4.6 IU/ℓ에서 32.8±7.8 IU/ℓ로, γ-GTP는 31.6±4.7 ㎎/ℓ에서 33.7±4.8 ㎎/ℓ로 조금씩 증가하였으나 모두 정상범위의 수치였다. The purpose of this study was to assess the effects of mulberry leaf extract supplement on blood glucose, glycated hemoglobin (HbA1C) and serum lipids in type Ⅱ diabetic patients, and also to assess safety in liver function after mulberry leaf extract supplement. The study was a randomized placebo-controlled trial and total 23 type Ⅱ diabetic patients were divided into a MLE group taking 1,000 ㎎ mulberry leaf extract supplement per day as experimental group and a placebo group taking 1,000 ㎎ cellulose powder supplement per day for 12 weeks. After 2 weeks of wash-out period, fasting blood glucose, HbA1C, serum lipid levels and liver function test were analyzed before and after treatment of 12 weeks. The general baseline char- acteristics, nutrient intake and life style factors of study subjects were similar between two groups during intervention. The concentrations of fasting blood glucose and HbA1C (p<0.05) decreased significantly after mulberry leaf extract supplement in MLE group, while there were no changes found in placebo group. We also found it showed that mulberry leaf extract supplement for 12 weeks decreased significantly (p<0.05) the fasting blood glucose in poor fasting blood glucose group and HbA1C concentration in poor HbA1C group. The concentrations of LDL-cholesterol (p<0.05) and triglyceride (p<0.01) decreased significantly in MLE group after 12 weeks of taking the supplement, while there were no changes found in placebo group. The mulberry leaf extract supplement for 12 weeks didn't show hepatotoxicity. These results suggested that mulberry leaf extract supplement could be effective in improving fasting blood glucose and HbA1C levels in the diabetic patients, specially having high concentrations of fasting blood glucose and HbA1C among type Ⅱ diabetic patients.

The purpose of this study was to determine the effects of the information characteristics of online fashion communities on relationship quality and WOM. The study also analyzed how the classification of online communities based on hosts makes differences in forming relationship quality. Data were collected from a total of 245 members from both communities (79 and 166, respectively) and analyzed with AMOS 6.0. For hypothesis testing, the study model was set with a structural equation modelling to examine the goodness of fit. The present study gained the following results: 1. The consensus of information in online fashion communities was found to have a negative relationship with the consumer-community relationship quality, while the information vividness and interactivity were found to have a positive relationship with the consumer-community relationship quality. 2. It was found that the higher the consumer-community relationship quality is, the more actively they accept and spread WOM. Thus, online fashion shopping malls would do best to take advantage of consumers’ frank, live and vivid information and active interaction among members in online communities. 3. Depending on the types of online fashion communities, the consumer-community relationship quality showed significant differences. The consumer-oriented community, therefore, compared to a business-centered one, was found to have a higher relationship quality.

大韓帝國期 ‘傳’類 歷史書와 그 歷史觀

梁正鉉(Yang Jung-hyun) 역사교육연구회 1999 역사교육 Vol.72 No.-

This paper intends to analyze biographies published in the Great Han Empire from the historical perspective. Biography is a type of historiography. It provides numerous sources for the value systems and historical consciousness at that time. This study focused on analyzing biographies and Its Historcal Perspective in the Great Han Empire, with relation to contemporary political spheres. ‘Gijunche(紀傳體)’ was considered as typical Oriental historiography. Biographical writing comprises an important part in ‘Gijunche’. Biography in East Asia was used to tell right from the wrongs. In Korea, it was around ‘Eulsaneukyak(乙巳勒約, 1905)’ that biographical writing got wide-spread. Persons who contributed to the saving or reinforcing of the country were chosen as the main characters of biographies. There were four distinct categories in the biographies. The first category aimed to overcome the crisis of the Great Han Empire by preserving the national essence. The second laid the primary focus on fortifying the country by learning from the foreign civilization. Foreign heroes who expanded their territories or increased the national wealth were the leading characters from this stance. Third, lessons were pursued from the heroes who saved their country which was in similar situation with the Great Han Empire. Three Founding Fathers of Italy were discussed in this context. Fourth and finally, great explorers appeared as the main character of the biography. Young adults were encouraged to raise progressive attitude toward the future through the reading of explorers’ biography. All these four categories were based on the heroism, which regards the hero as the chief power of history. Now, there are some people who believe in the power of ordinary men in history. ‘Figures’ is an essential factor in teaching and learning history. Biographical history instruction constitutes a significant part in contemporary history education. Biographies in the Great Han Empire needs reconsidering from the educational point of view.
