This study, based on an ethnographic field-research in Hwangryong marketplace at Jangsung, explores the transformational process of local community and local marketplace from the end of the 19th century. I attempt to use methodology of oral statement and memory. In socio-economic, political and cultural sence, Hwangryong market which made the 18th century was central place of Jangsung. It was famous of cattle marketplace from the end of Lee Dynasty. The heyday of Hwangryong market is vitalized in the ruling of Japan. Japanese government collect tax and agricultural products through this marketplace. After independence of 1945, the economic function of it was weakened, but the other side political function was strengthened. The socio-economic and cultural status of this market was revitalized after the end of Korean war notwithstanding trial of moving of marketplace. But peasant migration and mechanization of agriculture from the end of 1950' had been brought about a critical moment to Hwangryong marketplace as cattle market. The opening of Honam express road at 1973 was decisively weakened socio-economic, cultural function and role of this marketplace. Consequently, Hwangryong marketplace was transformed small local market. The identity of cattle marketplace was rarely remained in recent. This inclination will not be stopped if not linking to local festival or invention of local specialities.

현재 국내에서 사용되고 있는 신호등용 전구는 전량 해외에서 수입되는 백열전구로써, 낮은 발광효율($8.0{\sim}8.4lm/W$)과 짧은 수명(약 4,000 hours)으로, 지방 자치단체의 경우 전기에너지의 과소비와 과중한 전력요금 부담 잦은 유지보수로 관리비용이 증가하고 교통환경을 악화시키는 원인이 되고 있으며, 국가적으로는 첨두부하 증가, 귀중한 에너지 낭비 및 석유, 가스 등 발전용 화석연료 사용증가에 따른 환경오염을 유발하고 있다. LED(Light Emitting Diode. 발광다이오드)는 발광 특성상 열 발생이 적고, 특정 파장대의 단색광을 발광하는 광원으로써 전력소비가 매우 작고, 긴 수명, 양호한 환경 특성을 가지고 있다. 옥외에 노출되고, 점등이 길고 소등 횟수가 많으며 단색광을 필요로 하는 신호등에 적합한 것으로 평가되고 있다. 그러나 LED 신호등은 발광 원리 및 발광 방식이 기존의 전구식과 달라 현재 규정된 시험방법으로 직접 평가가 불가능하다. 따라서 우리나라의 경우 LED 제조기술은 세계적인 수준이나 LED 신호등에 대한 기술개발 및 보급은 현실적으로 어려운 실정이다. 본 논문에서는 국내 보급환경 구축을 위해 LED 신호등에 대한 시제품의 특성을 장시간의 옥외 시험을 통해 우리나라 환경 특성에 적합한 LED 교통 신호등 규격을 연구하고자 한다.

Conjugated linoleic acid (CLA) is the mixture of positional and geometric isomers of linoleic acid (LA, C18:2 $\omega$6), which is found abundantly in dairy products and meats. This study was peformed to investigate the anticarcinogenic effect of CLA in MCF-7 breast cancer cells. MCF-7 cell were treated with LA and CLA at the various concentrations of 15, 30, 60, 120 UM each. After incubation for 48 and 72 hours, cell proliferation, fatty acids incorporation into cell, peroxidation and activities of antioxidant enzymes were measured. Postaglandin E$_2$ (PGE$_2$) and thromboxane $A_2$ (TXA$_2$) were measured for the eicosanoids metabolism. There was no cell growth differences in both of LA and CLA treated MCF-7 cells at 48 hr incubation. Compared to LA, cell growth was decreased by CLA treatment according to increasing concentration at longer incubation times, respectively (p<0.05). Both of LA and CLA was incorporated into the cellular lipids 22~54% higher than in control but LA incorporation was not so linear as CLA according to concentration. Arachidonic acid (C20:4, $\omega$6) was synthesized after treatment of LA but did not in CLA, respectively. The lipid peroxide concentration in LA 120 $\mu$M group increased as 1.7 times as that in CLA 120 $\mu$M treated. The activities of antioxidant enzymes such as glutathione peroxidase and glutathione reductase were increased by the supplementation with CLA 120 $\mu$M at 72 hr incubation (p<0.001) compared to LA, otherwise activity of superoxide dismutase was not different in both. PGE$_2$ and TXA$_2$ levels were lower in condition of CLA treatments according to lower levels of arachidonic acids than those in LA treated group, respectively. Overall, the dietary CLA might change the MCF-7 cell growth by the changes of cell composition, production of lipid peroxide, activities of antioxidant enzymes and eicosanoid synthesis compared to dietary LA.

Very-long-chain acyl-CoA dehydrogenase (VLCAD) deficiency (OMIM#201475) is an autosomal recessively inherited metabolic disorder of mitochondrial long-chain fatty acid oxidation. The clinical features of VLCAD deficiency is classified by three clinical forms according to the severity. Here, we report a case of later-onset episodic myopathic form of VLCAD deficiency whose diagnosis was confirmed by plasma acylcarnitine analysis and" multigene panel multigene panel sequencing. A 34-year old female patient visited genetics clinic for genetic evaluation for history of recurrent myopathy with intermittent rhabdomyolysis. She suffered first episode of rhabdomyolysis with acute renal failure requiring hemodialysis at twelve years old. After then, she suffered several times of recurrent rhabdomyolysis provoked by prolonged exercise or fasting. Physical and neurologic exam was normal. Serum AST/ALT and creatinine kinase (CK) levels were mildly elevated. However, according to her previous medical records, her AST/ALT, CK were highly elevated when she had rhabdomyolysis. In suspicion of fatty acid oxidation disorder, multigene panel sequencing and plasma acylcarnitine analysis were performed in non-fasting, asymptomatic condition for the differential diagnosis. Plasma acylcarnitine analysis revealed elevated levels of C14:1 ($1.453{\mu}mol/L$; reference, 0.044-0.285), and C14:2 ($0.323{\mu}mol/L$; 0.032-0.301) and upper normal level of C14 ($0.841{\mu}mol/L$; 0.065 -0.920). Two heterozygous mutation in ACADVL were detected by multigene panel sequencing and confirmed by Sanger sequencing: c.[1202G>A(;) 1349G>A] (p.[(Ser 401Asn)(;)(Arg450His)]). Diagnosis of VLCAD deficiency was confirmed and frequent meal with low-fat diet was educated for preventing acute metabolic derangement. Fatty acid oxidation disorders have diagnostic challenges due to their intermittent clinical and laboratorial presentations, especially in milder late-onset forms. We suggest that multigene panel sequencing could be a useful diagnostic tool for the genetically and clinically heterogeneous fatty acid oxidation disorders.

동식물성 기름과 메탄올의 전이에스테르화 반응에 의해 생산되는 바이오디젤은 환경친화성과 지속가능성이 인정됨에 따라 그 생산량이 급격히 증가하고 있어 대두유, 유채유, 팜유 등의 원료유 부족과 가격 상승, 수급 불안정 등의 문제가 대두되고 있다. 이를 해결하기 위한 방안으로 유리지방산 함량이 높은 저가유지 자원(폐식용유, 폐돈지, 폐우지, soapstock, trapped grease)과 새로운 오일 작물을 이용한 생산 기술 연구가 활발히 진행되고 있다. 본 연구에서는 비활용 해외 열대작물 씨앗에서 착유한 식물성 오일을 정제하여 바이오디젤 원료유를 생산하는 과정에서 발생하는 폐기물(폐유, 폐수)의 경제적 처리 방안으로 유화유 제조 원료(벙커C유, 물)와 유화유 제조 첨가제(무기계, 유기계)로 활용 가능성을 검토하였다. 열대작물 오일의 물성 분석 결과 고형물, 수분, 인지질(phospholipid), 유리지방산(free fatty acid) 함량이 기존 원료유보다 매우 높게 나타났다. 인지질은 바이오디젤 제조 반응후 에스테르와 글리세린의 층분리를 방해하고 유리지방산은 염기촉매와 결합하여 지방산염을 생성해 생산 수율을 감소시킨다. 고형물과 수분 역시 촉매반응에 악영향을 가지나 여과와 감압증발에 의해 쉽게 제거가 가능하다. 유리지방산은 산촉매 에스테르화 반응에 의해 제거가 가능하다. 인지질은 탈검(degumming) 과정을 통해 제거하며 탈검은 수용성 탈검, 산 탈검, 세정 공정으로 구성된다. 착유한 원료유의 고형물을 제거 후 물과 수세하여 수용성 인지질을 수화하여 층 분리해 제거하고 상층의 오일은 추가적인 산 탈검을 수행한다. 그 뒤 세정을 통해 사용된 탈검제인 산과 추가적으로 수화된 인지질을 제거하게 된다. 이러한 3단계의 탈검 과정에서 하층으로 오일과 물이 폐기물로서 배출되며 본 연구에서는 배출 폐기물을 다시 층분리하여 오일층과 물 층으로 구분하여 유화유 제조에 사용되는 벙커C유, 물, 그리고 기존 유기계 및 무기계 유화제의 대체 가능성을 조사하였다. 유화 연료유는 기름과 물을 균일한 분산상으로 혼합한 연료유로 연소시 오일계 성분의 미연분을 감소시켜 연료 효율 제고와 배출가스 성상을 개선하기 위해 개발되어 왔다. 본 발표에서는 다양한 종류의 상용 첨가제 및 바이오디젤 원료유 생산 폐기물을 활용해 유화 연료유를 제조하였으며 각 유화유의 장시간의 상(phase) 안정성을 비교하였다. 바이오 폐기물 중에는 천연 계면활성제(surfactant)인 인지질이 다량 함유되어 있어 기존의 무기계 및 유기계 유화제보다 상 안정성이 우수하게 나타났으며 바이오디젤 원료유 생산 공정의 폐기물인 폐유과 폐수의 활용이 가능한 것으로 나타났다.

For utilization of buckwheat as vegetable, rutin and minerals of the leaves at growing stages were investigated. The contents of crude protein and crude fat in seed of nine improved kinds of Korean buckwheat were $16.2{\sim}20.4%$ and $2.2{\sim}2.9%$ respectively. Ash content $(2.4{\sim}4.3%)$ in the improved kinds were higher than those in the native kinds. Content of crude fiber in the improved kinds were lower than those in the native kinds. Suwon 11 (0.12%) and Suwon 5 (0.11%) had high contents of rutin among the improved kinds. The composition of K, Ca, Mg and Fe in the improved kinds were better than that in the native kinds. Vegetable of the improved kinds had higher content of crude protein than the native kinds. Suwon 10 and 11 among vegetables of the improved kinds contained high amount of crude protein. Swon 5 had the highest content of rutin (0.40%) in the improved kinds. Suwon 5 was tested for the changes of rutin content in growing. Rutin content was 0.40% in the first growing stage, whereas 1.32% in the final growing stage. Insoluble materials in 10% HCl was also 69.8% in the first growing stage, whereas 4.68% in the final growing stage. Iron and calcium contents were increased with growing of vegetable.

Local culture is a cultural heritage that has come down from generation to generation in the natural environment of a region. It includes history, tradition, natural features, art, and historic relics. The Academy of Korean Studies has complied "The Encyclopedia of Korean Local Culture" using those local culture contents. Local culture content shave the features of documentary, such as authenticating the source, and managing hierarchy structure. Thus, to deal with local culture contents, a "circular knowledge information management system" is sought for that helps basic, fragmentary, and high-level information to circulate to create new knowledge information within the system. A user of this circular knowledge information management system is able not only to collect data directly in it, but also to fetch data from other database. Besides, processing the collected data helps to create new knowledge information. But, it's very difficult to sustain the features of the original hierarchy bearing meaning contained in the various kinds of local culture contents when building a new database. Moreover, this kind of work needs many times of correction over a long period of time. Therefore, a system in which compilation, correction, and service can be done simultaneously is needed. Therefore, in this study, focusing on the case of "The Encyclopedia of Korean Local Culture", I propose a XML-based digital compilation management system that can express hierarchy information and sustain the semantic features of the local culture contents containing lots of ancient documents, and introduce the expanded functions developed to manage contents in the system.
