대전광역시 무형문화재 제2호 신석봉 법사(法師)에 대한 현지 조사를 통하여 앉은굿의 기초이며 핵심인 안택(安宅)굿의 음악을 연구함으로써 다음과 같은 음악적 특징을 밝힐 수 있었다. 앉은굿의 경문(經文) 구송(口誦)을 위한 반주 악기로는 북과 꽹과리가 쓰이는데, 법사의 오른편에 놓인 북은 경문(經文)을 읊을 때 기본 장단을 규칙적으로 조용히 연주해 반주 역할을 하고, 법사의 왼편에 놓인 꽹과리는 경문 악절의 휴지부를 메우는 역할을 하므로 각 고장(鼓杖) 에 맞는 리듬 패턴을 다양한 변주 형태로 연주한다. 이와 같이 경문을 구송하다 법사의 호흡이나 경문의 내용에 따라 잠깐의 휴지부를 갖고, 그 사이를 꽹과리 변주 리듬으로 메우는 것은 국악 연주 방식 중 하나로, 합주 시 주선율 연주 악기들이 쉬는 사이에 다른 악기가 주선율을 이어서 연주하는 '연음형식(蓮音形式)'과 같다. 이 악기 반주에 맞추어 구송되는 안택굿 경문의 장단 주기는, 대체로 3소박4박의 '외마치 장단', 3소박8박의 '두마치 장단', 그 외에 '외마치 장단'과 같이 3소박4박의 리듬형을 가지고 있지만 그 템포가 매우 빠른 '세마치 장단', 다양한 리듬패턴 없이 획일화된 리듬형을 일률적으로 막치는 '막고장', 그리고 그 일반적인 장단형에서 벗어난 '못갖춘 장단의 다섯 가지 유형이 있다. 신석봉 법사는 안택굿 전반의 각 처에 걸쳐 '두마치 장단, 주기로 소위 그가 청(淸)이 라고 말하는 창(唱) 즉 소리를 하고 있으며, 오직 안택 마지막 처인 대문에서 구송되는 '퇴송경'만이 '외마치 장단' 주기로 연주하고 있음을 알 수 있었다. 그 외에 비교적 앞의 두 장단보다 그 템포가 빠른 '세마치 장단'과 '막고장'은 무당이 춤출 때와 신장대 잡을 때 경(經) 없이 악기 연주로만 행해졌다. 특히 춤출 때 연주되는 '세마치 장단'은 비교적 느린 템포에서 시작하여 점점 몰아치다가 다시 느린 템포로 돌아오는데, 이와 같이 우리 음악의 대표적인 빠르기 형식 중 하나인 느림-빠름-느림의 형태를 보이고 있다. 음조직에 있어서는 구성음이 mi-la-do'-re'이며, 그 주요 음이 mi-la-do'의 완4도+단3도 음진행을 보이고 있는 메나리토리의 음구성이나 음진행과 같지만, 첫 음인 mi음을 떨고 re'에서 do'로 흘러내리는 시김새를 갖는 전형적인 메나리토리 시김새의 특징이 조금 약하게 보이고 있다. 이는 아마도 전 지역에 걸쳐 그 음악적 어법(語法)이 경상도에 비해 비교적 약한 충청도라는 지역적인 음토리의 결과일 것이라 생각한다. 또한 안택굿 음악의 가사 붙임에 따른 리듬형태는, 비교적 그 템포가 다른 경문들에 비해 빠르고 la음이 곡 전반에 걸쳐 지속적으로 나타나는 '퇴송경'에서만은 오직 '실라빅(syllabic)'한 리듬형을 보이지만, 일반적으로 '신코페이션(syncopation)'이나 '멜리스마틱(melismatic)' 식의 리듬형으로 구성되어 있다. 마지막으로 각 경문에 따른 음구성을 간략히 살펴 본 결과, 음구성은 일반적으로 la음의 비중이 크며, la음을 중심으로 la-do' 상행과 la-mi 하행의 단3도, 완전4도 음정의 음진행을 주로 보이고 있다. 또한 전체 곡의 빠르기는 M.M.♩.=116-184정도의 빠르기에서 움직이고 있지만, 굿 전반에 걸쳐서는 대부분 경문 구송에 알맞은 빠르기인 M.M.♩=120-140 사이의 템포 즉 '보통빠르기' 정도로 진행되었다.

As the global market becomes more competitive, manufacturing industries face relentless pressure caused by a growing tendency of greater varieties of products, shorter manufacturing cycles and more sophisticated customer requirements. Efficient and effective supplier selection and order allocation decisions are, therefore, important decisions for a manufacturer to ensure stable material flows in a highly competitive supply chain, in particular, when customers are willing to accept products with less desirable product attributes (e.g., color, delivery date) for economic reasons. This paper attempts to solve optimally the challenging problem of supplier selection and order allocation, taking into consideration the customer flexibility for a manufacturer producing multi-products to satisfy the customers' demands in a multi period planning horizon. A new mixed integer programming model is developed to describe the behavior of the supply chain. The objective is to maximize the manufacturer's total profit subject to various operating constraints of the supply chain. Due to the complexity and non-deterministic polynomial-time (NP)-hard nature of the problem, an improved genetic approach is proposed to solve the problem optimally. This approach differs from a canonical genetic algorithm in three aspects: a new selection method to reduce the chance of premature convergence and two problem-specific repair heuristics to guarantee feasibility of the solutions. The results of applying the proposed approach to solve a set of randomly generated test problems clearly demonstrate its excellent performance. When compared with applying the canonical genetic algorithm to locate optimal solutions, the average improvement in the solution quality amounts to as high as ten percent.

Green tea (Camellia sinensis) is one of the most popular beverages in the world and has been acknowledged for centuries as having significant health benefits. (-)-Epigallocatechin-3-gallate (EGCG) is the most abundant catechin in green tea, and it has been reported to have health benefit effects. Peroxisome proliferator-activated receptor ${\gamma}$ coactivator $(PGC)-1{\alpha}$ is a crucial regulator of mitochondrial biogenesis and hepatic gluconeogenesis. The objective of this study was to investigate whether EGCG from green tea can affect the ability of transcriptional regulation on $PGC-1{\alpha}$ mRNA expression in HepG2 cells and 3T3-L1 adipocytes. To study the molecular mechanism that allows EGCG to control $PGC-1{\alpha}$ expression, the promoter activity levels of $PGC-1{\alpha}$ were examined. The $PGC-1{\alpha}$ mRNA level was measured using quantitative real-time PCR. The -970/+412 bp of $PGC-1{\alpha}$ promoter was subcloned into the pGL3-Basic vector that includes luciferase as a reporter gene. EGCG was found to up-regulate the $PGC-1{\alpha}$ mRNA levels significantly with $10{\mu}mol/L$ of EGCG in HepG2 cells and differentiated 3T3-L1 adipocytes. $PGC-1{\alpha}$ promoter activity was also increased by treatment with $10{\mu}mol/L$ of EGCG in both cells. These results suggest that EGCG may induce $PGC-1{\alpha}$ gene expression, potentially through promoter activation.

C. neoformans-associated cryptococcosis is primarily a disease of immunocompromised persons, has a world-wide distribution, and is often spread by pigeons in the urban environment. In contrast, C. gattii causes infection in normal hosts, has only been described in tropical and semi-tropical areas of the world, and has a unique niche in river gum Eucalyptus trees. Cryptococcosis is acquired through inhalation of the yeast propagules from the environment. C. gattii has been identified as the cause of an emerging infectious disease centered on Vancouver Island, British Columbia, Canada. No cases of C. gattii-disease were diagnosed prior to 1999; the current incidence rate is 36 cases per million population. A search was initiated in 2001 to find the ecological niche of this basidiomycetous yeast. C. gattii was found in the environment in treed areas of Vancouver Island. The highest percentage of colonized-tree clusters were found around central Vancouver Island, with decreasing rates of colonization to the north and south. Climate, soil and vegetation cover of this area, called the Coastal Douglas fir biogeoclimatic zone, is unique to British Columbia and Canada. The concentration of airborne C. gattii was highest in the dry summer months, and lowest during late fall, winter, and early spring, months which have heavy rainfall. The study of the emerging colonization of this organism and subsequent cases of environmentally acquired disease will be informative in planning public health management of new routes of exposure to exotic agents in areas impacted by changing climate and land use patterns.

This study examines the costume artifacts discovered in the burial site of Choi Kyung Sun(1561~1622), which was moved from Gangwon in Gangrung Province. About 30 artifacts, including costumes, were recovered from Choi Kyung Sun's grave. The collection of men's coats discovered in the grave consisted of a Dallyeong (Official's robe), Jing-nyeong(Man's coat), Jungchi-mak(Man's coat), Cheolrik(Man's coat), Chang-ui(Man's coat), Gwang-su-ju-ui(Man's coat), and Do-po(Man's coat). Han-sam(Undershirts), Jeo-go-ri(Jacket), and trousers were also recovered, along with several items made of textiles, such as the cloth used to shroud and wrap the body. The costume artifacts recovered from Choi Kyung Sun's grave have several characteristics that distinguish them from other early 17th-century costume artifacts. Firstly, the body had a hairband made from horsehair. Secondly, the men's trousers were of the type worn before the Japanese Invasion(1592~1597). Thirdly, the style of the coats' sleeves, when compared with artifacts from other regions, was from an earlier era. Through these costume artifacts, it can be inferred that people who lived in the Gangwon Province, which was far away from Seoul, continuously wore outfits from before the Japanese Invasion, and trends spread slowly.

2001년부터 2003년에 걸쳐 수확 후 과일가게에서 판매되는 참외의 썩음증상으로부터 Fusarium spp.를 분리하였다. 병든 과실들은 균사로 덮여 있었고 결국 물러 썩었다. 병의 시작은 주로 과실이 달렸던 부위, 꽃이 달렸던 부위 그리고 열매 표면에 병이 시작되었다. 병이 진전됨에 따라 물러 썩는 열매의 표면에는 흰색에서 분홍빛의 균사로 덮혔다. 이들 병든 과실로부터 분리된 Fusarium spp.를 기존에 보고된 균학적 내용과 비교하여 동정한 결과 Fusarium equiseti, F. graminearum, F. monliforme, F. proliferatum, F. sambucinum, F. semitectum으로 동정되었다. 이들 균의 병원성을 조사하기 위해 건전한 참외에 인위적으로 만든 상처와 무상처에 접종한 결과 접종 이틀후, 상처 접종 부위에 기중균사가 형성되었고, 병이 진전됨에 따라 물러 썩었다. 비록 참외에서 Fusarium spp.가 야기하는 열매썩음병은 국내에서 이미 보고된 바가 있으나, 이와 관련된 종에 대해서는 보고된 적이 없다. 따라서, 이 연구를 통해 Fusarium spp.에 의한 수확 후 참외의 열매썩음병을 국내에서 처음으로 보고하는 바이다.

Objective : The writer has come to see that a study of the Theory of Ministerial Fire of JuDanGae presupposes a study of earlier theories of fire. Therefore, I have analyzed and studied the theories of fire presented by medical doctors since "Nae Gyeong(黃帝內經)" Method : To begin with, I have studied the concepts of grand fire(壯火) and small fire(少火), imperial fire(君火) and ministerial fire(相火) in "Nae Gyeong", and have construed the meaning of human fire(人火) and dragon fire(龍火) by Wang Bing(王冰), and fatty fire(膏火) by Sohn Sa-mak(孫思邈). Next, I have studied true fire(眞火) by Huh Sook-mi(許叔微) and true yang(眞陽) and pit fire(坎火) by Eom Yong-hwa(嚴用和), Theory on Right Kidney as the Gate of Life and Ministeiral Fire(右腎命門相火說) by Yu Wan-so(劉完素), and the reason why Jang Wan-so(張元素) asserted Theory of Three Burners as Ministerial Fire(三焦相火說). Result : I have understood the influence that the concepts of grand fire and small fire, imperial fire and ministerial fire in "Nae Gyeong"have exercised on the later medical doctors, and have also understood the physiological and pathological Fire that influences the human body. Moreover, I have seen that Fire, as discussed by scholars from Huh Sook-mi and Eom Yong-hwa to Yu Wan-so and Jang Wan-so, made great contribution to the later development of Theory of the Gate of Life, getting its entire picture in Eum Hwa. Conclusion : Seeing that the theories of Fire presented by medical doctors since "Nae Gyeong" and prior to JuDan-Gae had great influence on the later development of Theory of the Gate of Life, I have come to understand that along with Eum Hwa by Lee Dong-wan, they must precede a study of the Theory of Ministerial Fire of JuDan-Gae.

In this study, the effects of corn peptide consumption on plasma lipid profiles were investigated in high cholesterol diet-fed rats. Male Sprague-Dawley rats (n = 21) were fed with corn peptide-free (control) diet, diets containing 2% or 5% com peptide for 5 weeks. Hypercholesterolemia was induced by adding l% cholesterol and 0.5% cholic acid to all diets. No difference was found in food intake and body weight gain among groups. The corn peptide treated groups showed significant improvement in the plasma level of HDL-cholesterol (p<0.05) compared to the control group, while the plasma total cholesterol and LDL-cholesterol were not affected.5oio corn peptide supplemented diet reduced plasma level of triglycerides (p<0.05) The atherogenic index was decreased in the corn peptide treated groups. These results suggest that consumption of corn peptide may lead to an amelioration of metabolic syndrome as well as a reduction of cardiovascular disease and hyperlipidemia through increasing the level of HDL-cholesterol, and decreasing the level of triglycerides in plasma.

This study was performed to investigate the lipolytic effects of Portulaca oleracea L. extract in 3T3-L1 adipocytes. The Portulaca oleracea L. was extracted with extrusion method using twin-screw extruder under $58{\sim}60rpm$ screw speed, $4{\sim}5kg/hr$ feed rate, $140^{\circ}C$ extrusion temperature. The lipolytic action of Portulaca oleracea L. extract was estimated by measuring the amount of glycerol and free fatty acids (FFA) released from 3T3-L1 adipocytes and by measuring the cellular lipid content in 3T3-L1 adipocytes. The hormone sensitive lipase (HSL) mRNA level was analyzed using quantitative real-time PCR. The Portulaca oleracea L. extract at 1 to $100{\mu}g/ml$ suppressed lipid accumulation. The release of glycerol and FFA into the medium, and the mRNA level of HSL were significantly increased by the addition of Portulaca oleracea L. extract at dose-dependent manner. In conclusion, the Portulaca oleracea L. extract was suggested to have the lipolytic effect through release of lipolytic products (FFA and glycerol) of triacylglyceride to the culture medium and suppression of lipid accumulation via up-regulation of HSL gene expression in 3T3-L1 adipocytes.
