  • 부도는 삼국시대 신라초기의 인물로 한국최초의 수학자라고 볼 수 있다. 부도는 1천7백 전 지금의 조달청과 비슷한 물장고사무를 맡았는데 그때는 화폐를 사용하지 않아 당대 최고의 계산능력을 지닌 사람을 인정을 받은 인물이다. 귀족아닌 서민으로 6두품이라는 최고의 벼슬에 오른 부도는 「삼국사기」에 '가난하지만 아첨하는 일이 없이 문서와 수확에 익숙해 임금이 불러 문장고 사무를 맡겼다'라고 기록되어있다.

  • 본 논문에서는 개화기 소설과 신문사설에 나타난 담화방식을 연구한 것이다. 개화기 소설과 신문 사설은 당시 대표적인 담론 매체였다. 대중들에게 쉽게 전달할 수 있는 담화방식은 개화기소설의 경우 대화체 토론체 연설체 담화방식으로 나타났다. 이는 신문 사설이 갖고 있는 한계인 설명 추상보다 진일보한 것으로 당대의 시대정신을 잘 구현한 것으로 볼 수 있다.

  • 연구원 초년 시절에 ISDN, 전화선 모뎀 규격 등을 담은 ITU-T 권고안을 (당시는 CCITT 권고안) 보면서 바이블처럼, 금과옥조처럼 신성시 할 때가 있었다. 그러나 천하의 ITU-T 권고안도 실수가 더러 섞여 있고 규격에 반영된 기술도 세계 최고가 아닌 적당한 타협에 의한 결과물이 더러 있다는 걸 알게 되기까지는 그리 오랜 시간이 필요하지 않았다. 그래서 국제 표준이라는게 꼭 당대 최고의 기술의 결정체라기 보다는 토론과 협상, 절충과 거래에 의한 종합적인 고뇌의 산물이자 예술품이라는 결론을 내리게 되었다. 이번 글에서는 필자가 알고 있거나 경험했던 표준에서 절충의 사례를 몇 가지 알아보고 향후 표준을 만들어 갈때 길잡이가 되기를 기대한다.

A Meta-Analysis of the Effects of Exercise Programs on Glucose and Lipid Metabolism and Cardiac Function in Patients with Type II Diabetes Mellitus (제2형 환자를 위한 운동프로그램이 당대사, 지질대사 및 심폐기능에 미치는 효과에 대한 메타분석)

  • Purpose: This study was a systematic review and meta-analysis of the effects of exercise programs in patients with type II diabetes mellitus. Method: Two investigators systematically searched and reviewed English articles from PUBMED from 1988 to 2004, selecting randomized controlled trials on structured exercise programs for DM patients. Out of 87 studies identified, a meta analysis was done for eleven studies which satisfied inclusion criteria and focused on glycemic indices, lipid indices, and cardiac function indices. Results: The means and standard deviations were compared for experimental groups that received exercise-only or exercise and diet programs and control groups that received no intervention or only diet education. The groups were considered homogeneous as the p value of the Q score in each variable group was over 0.05. The experimental groups demonstrated a moderate positive effect on HbA,c and $VO_{2max}$ (d=0.55 & 0.5), and a small positive effect on fasting blood glucose and cholesterol (d=0.38 & 0.27) compared to the control groups. HDL and LDL cholesterol levels, however, showed a very low positive effect (d=0.11 & 0.12) in the experimental groups. Aerobic exercise was more beneficial than resistance exercise on $HbA_1c$ (d=0.59 vs 0.28) in the groups. Conclusions: Regular exercise has a positive effect on $HbA_1c$, fasting blood glucose, total cholesterol, HDL cholesterol, LDL cholesterol, and $VO_{2max}$ in Type 2 diabetic patients.

  • The ethanol extraction yield of Liriope platyphylla(Lp) was about 30.7% by extract apparatus. This study was done to investigate the carbohydrate metabolism related enzyme activities effects of Lp in streptozotocin (STZ)-induced diabetic rats. The contents of serum glucose, triglyceride (TG) were significantly decreaed in Lp treated group compared to the those of STZ-control group, also content of Total cholesterol was decreased. High density lipoprotein (HDL)-cholesterol was increased in Lp treated group. The activity of glucose-6-pase(G-6-Pase) was significantly decreased in Lp treated group. Also the activity of glucokinase(Gk) was increaed in Lp treated group. The content of hepatic glycogen was significantly increaed in Lp treated group. These results indicated that ethanol extract of Lp would have antidiabetic effect in STZ-induced diabetic rats.

  • This study was conducted to review the reading education and the required reading list for elementary school students which is being executed as part of China's language education. For this purpose, extracurricular reading list of language curriculum standard enacted in 2011 was investigated and required list for elementary school students recommend by China's Ministry of Education education in 2012 and 2015. Furthermore, the comparative analysis of extra curricular reading list and two types of required reading list recommended by the Ministry of Education. As a result of investigation on two types of lists of required reading, it was found out that there are lots of fairy tales and science book types by genre, lots of British book by nation, and as a result of comparison with extra curricular reading list, it was found out that there is higher rate of reflection of oversease books and Chinse authorsd, and that there were higher rate of reflection of contemporary literary works and science. Based on these findings, studies on Chinese authors, Chinese fairy tales, and contemporary literary works and studies and recommendations on various subjects were suggested.

  • The purpose of this study is to determine the effect of diabetes education program on Glucose Metabolism(blood sugar, HbA1c) and Lipid Metabolism(total cholesterol, triglyceride, low density lipoprotein, high density lipoprotein), Self-efficacy in non-insulin independent diabetes mellitus. The study design was a non equivalent control group pre-test post-test design. Data for the study were collected from March 12 to June 19, 2001. Sixty-two research subjects were assigned to experimental(36) and control(26) groups. The collected data was analyzed using the Chi-Square test, t-test by spsswin program The results are as follows : 1. Experimental group had higher level of glucose metabolism than control group(FBS ; t=-3.317, p=.002, HbA1c; t=-4.956, p=.000). 2. Level of lipid metabolism were partly a significant different between experimental group and control group(Triglyceride ; t=-2.108, p=.039). 3. Experimental group had higher efficacy score than control group(t=4.651, p=.000). In conclusion, the study supported the effects of diabetes education program to increase metabolism an d self-efficacy. Further study with a longitudinal design is suggested to verify the effect of diabetes education program in NIDDM and standardized diabetes education program.

  • The present study was designed to investigate the antidiabetic effect of Cordyceps militaris on activities of hepatic glucose-regulating enzymes, such as glucokinase (GK), pyruvate dehydrogenase (PDH) and acetyI-CoA carboxylase (ACC). We have isolated the active compounds, CM-A and CM-B from C. militaris and the extracts are under investigation to determine their mechanism of action. Hepatic GK, PDH and ACC activities were significantly (p < 0.05) increased compared with the control. Treatment with CM-A led to a rise in percentage of enzymes by 380$\%$,396$\%$ and 286$\%$, respectively, relative to control levels. CM-B were 329$\%$, 312$\%$ and 239$\%$, respectively. The increase in GK and ACC activities was linearly proportional with increased ratio of CM-A. Our findings suggest that C. militaris exerted antihyperglycemic potency, which is thought to be mediated through activation of GK, PDH and ACC enzymes related to glucose metabolism directly or indirectly and therefore C. militaris is promising as antidiabetic functional foods.

  • This article aims at a discourse analysis on the selected 1970s Myungrang Manwhas, in the cases of Ggubungi, Doggaebi Gamtu, Yochul Balmyungwang. For the analysis, the history, pre-censorship, and distribution structure of Myungrang Manwha are referenced, as well as the considerable changes and developments on the definition of 'myungrang' since the 1920s. In employing Foucauldian discourse analysis to the texts, the selected Myungrang Manwhas are analyzed as discursive formation, which emerged within the social relations of the era; the characters' dialogues are analyzed as statement. The analysis examines the discourses that the texts disseminated, and the social context of the utterance. It is demonstrated that the Myungrang Manwhas are forms of representation, which implies 'the contested acquisition on capital and power', 'the emphasis on nationalist aspects', and 'the interpellation and discipline of subject active' of the time. Moreover, it is revealed that the forms of control, such as pre-censorship, were the articulation of the will to power, which drove the discoursive formation to function as an apparatus that meticulously constituted the ruling ideology. In conclusion, the Myungrang Manwhas are rather texts that encompasses political and social context of the era than a mere comic relief.
