This study is an attempt to prove a relationship between Le Corbusier's utopian attitude towards nature and architectural ideology and ideology by a form of inquiry into sociological interests. That is to find out contradictions and limitations in Le Corbusier's architectural world, namely particularity of his ideology by exploring the base entangled with special interests in the society up until formation of his architectural language. A process of this study is by; 1. Examining of background which affected Le Corbusier's attitude towards nature until the nature became his architectural language; 2. An analysis of Le Corbusier's architectural works. That is, this study's main interest is on formation of Le Corbusier's architectural language by his attitude towards nature which present in residential field especially focused on Villa Meyer and Villa Savoye, two best examples of his villa. 3. This study have a goal to investigate that utopian and ideological conception in architecture of Le Corbusier have a dialectic relationship between them. This goal can be achieved by observing in what ways Le Corbusier's utopian attitude towards nature is expressed in residential architectural language and researching into his inconsistent architectural ideology derived from applying architectural language present in villa to pre-fabricated apartment houses.

Deterioration of jerky during storage is a major concern; this is usually combated with natural or synthetic antioxidants. This study aimed to evaluate the quality characteristics of semi-dried restructured jerky with and without loquat leaf extract (LE) powder and ascorbic acid (AA) during storage for 180 days. The jerkies were formulated with 0%, 0.15%, and 0.3% LE and/or 0.05% AA (Control, no antioxidant; AA, 0.05% AA; LE 0.15, 0.15% loquat LE; LE 0.15-AA, 0.15% loquat LE+0.05% AA; LE 0.3, 0.3% loquat LE; LE0.3-AA, 0.3% loquat LE+0.05% AA). LE is a phenolic compound, whose 1,1-diphenyl-2-picrylhydarzyl radical scavenging activity and metal chelating activity were found to be higher than AA. All antioxidant combinations having higher LE concentration and containing AA were effective in delaying protein and lipid oxidation compared to the control or AA. At the end of storage period, LE 0.15-AA and AA had higher CIE a^* and lower shear force than the control. Therefore, the combination of 0.15% LE and 0.05% AA can result in reduced protein and lipid oxidation without any negative effect on the quality characteristics of semi-dried restructured jerky.

Midfacial retrusion is one of characteristics of cleft patients due to underdevelopment of the midface. In this case, Le Fort II advancement is indicated. But there has not been reported on intraoral approach to Le Fort II osteotomy for correction of midface, which traditional technique resulted in facial scar. To overcome the problems, Le Fort II osteotomy via only intraoral approach named 'Intraoral Le Fort IT osteotomy' was developed by Choung in 1994, this technique was applied to cleft patients. A new technique of Intraoral Le Fort IT osteotomy for correction of midface in cleft patients was successfully carried out with good results. This technique showed no noticeable relapse nor complications, which is reported.

Purpose: This paper is an attempt to explicate the principle of space and form-making in Le Corbusier's architecture from the viewpoint of integrating and relating architecture with the natural landscape. It shows thereby how the geometrical element of architecture and the non-geometrical element of the nature coexist in terms of form. It also explains how space is deployed for the construction of cognitive system between natural landscape and architectural scenery in terms of space, hoping to make a contribution to design method of contemporary house as an elementary datum. Method: Three issues are studied, focusing on the designs around nineteenth thirties in the earliest phase of Le Corbusier: How architectural form and nature is related, how natural greens is introduced into urbanism, and how natural landscape is introduced to house design. 1) it is studied how the relation between the nature and the formal elements of purism in Le Corbusier's architecture is formed. 2) it is studied how the relation between the nature and architecture proposed in Le Corbusier's urbanism is formed. 3) Le Corbusier's "four compositions" is analyzed in terms of relation-formation between architectural space and the nature. 4) it is studied how the natural landscape is introduced to Le Corbusier's house-design in the form of architectural promenade. Result: It has been found out that the natural landscape in Le Corbusier's architecture is not just a simple background, but a necessary element for the consummation of form and space in his architecture, and that architectural inspiration is maximized with coexistence with nature.

목 적 : Lewis b($Le^b$) 항원과 BabA 단백은 H. pylori가 위점막에 부착하는 것과 연관이 있는 것으로 알려져 있다. 소아에서 H pylori 감염에 대한 위점막의 면역 반응은 성인에서의 반응과 차이가 있을 것으로 추정되지만 Le 항원의 발현에 관한 연구는 매우 드물다. 이에 저자들은 국내 소아 H. pylori 양성 환자의 위점막에서 Le 항원의 발현 양상을 알아보기 위하여 본 연구를 시행하였다. 방 법 : 2002년 1월부터 2004년 1월까지 상부 위장관 증상 때문에 소아과를 방문하여 내시경 검사를 시행받은 소아 환자를 대상으로 하였다. 위전정부에서 최소한 2개 이상의 조직 검체를 생검하여 CLO 검사와 조직 특수 염색(Warthin-starry) 검사를 각각 시행하여 모두 양성인 경우에 H. pylori에 감염된 것으로 판정하였다. H. pylori 양성 35명과 H. pylori 음성 19명의 위점막 파라핀 조직에서 DNA를 추출하여 cagA, babA2 특이 시발체를 이용하여 PCR을 시행하였다. 위점막 생검 조직을 대상으로 $Le^a$, $Le^b$, $Le^x$와 $Le^y$ 항체를 사용하여 면역조직화학적 염색을 시행한 다음 각각의 Le 항원의 발현 정도를 평가하였다. 결 과 : H. pylori 양성 환자에서 $Le^a$ 항원은 60%(21명/35명), $Le^b$ 항원 97%(34명/35명), $Le^x$ 항원 88%, $Le^y$ 항원은 100%에서 발현이 확인되었다. H. pylori 음성 환아군에서는 $Le^a$, $Le^b$, $Le^x$ 및 $Le^y$ 항원이 각각 52%, 100%, 89%, 100%에서 발현되었다. H. pylori 양성 유무에 따른 $Le^b$ 항원 발현의 차이는 없었다. CagA 및 babA2 유전자는 H. pylori 양성 환자군 중 각각 65.7%(23명/35명), 25.6%(8명/35명)에서 확인되었다. Lewis 항원들의 발현에 따른 H. pylori 감염, cagA 양성 및 babA2 양성율의 차이는 없었다. 결 론 : 국내 소아의 위점막에서 높은 $Le^x$와 $Le^y$ 항원의 발현율을 확인할 수 있었으나 H. pylori 감염 및 babA2의 양성 여부와는 관련이 없었다. Lewis 항원 이외의 다른 점막 수용체들과 세균 독소들에 대한 지속적 연구가 필요할 것으로 생각된다.

Light elevated temperature induced degradation (LeTID) was noted as an issue in multi-crystalline silicon solar cells (MSSC) by Ram speck in 2012. In contrast to light induced degradation (LID), which has been researched in silicon solar cells for a long time, research about both LeTID and the mechanism of LeTID has been limited. In addition, research about LeTID in single-crystalline silicon solar cells (SSSC) is even more limited. In order to improve understanding of LeTID in SSSC with a passivated emitter rear contact (PERC) structure, we fabricated four group samples with boron and oxygen factors and evaluated the solar cell characteristics, such as the cell efficiency, $V_{oc}$, $I_{sc}$, fill factor (FF), LID, and LeTID. The trends of LID of the four group samples were similar to the trend of LeTID as a function of boron and oxygen.

This study is intended to analyze the way of incorporating the effect of natural light into the architectural space design by Le Cobusier. The composition of modem architectural space is significantly different from that of classical architecture. Such transition is attributable to the change of tectonic method which was supported by the development of new materials and structural systems. In addition, the effect of natural light systems which is one of the main elements in architectural space has undergone significant changes in modern ages. Moreover, Le Corbusier introduces the new concept of natural light in his works. By bringing the above two trends together, this study analyzed the way how Le Cobusier applied light effect in his works. Specifically, findings regarding the 'traffic flow in the space' with the light, 'elevation effect' with the 'Brise soleil' in Le Cobusier's works were presented. And also the way of lighting the object in the space was presented.

Among the classification of maxillary fracture, the Le Fort classification is the best-known categorization. Le Fort (1901) completed experiments that determined the maxilla areas of structural weakness which he designated as the "lines of weakness". According to these results, there are three basic fracture line patterns (transverse, pyramidal and craniofacial disjunction). A transverse fracture is a Le Fort I fracture that is above the level of the apices of the maxillary teeth section, including the entire alveolar process of the maxilla, vault of the palate and inferior ends of the pterygoid processes in a single block from the upper craniofacial skeleton. Le Fort fractures result in both a cosmetic and a functional deficit if treated inappropriately. In this article, authors review the management of a Le Fort I fracture with a case-based discussion.

Architects and designers of the 20th Century made various efforts to establish new design languages reflecting the changes of society, the times, and environment. They used furniture, especially chairs, as controversial items of aesthetic value, society and ideology. Le Corbusier and Alvar Aalto are furniture designers as well as architects, who adopted this ‘spirit of the times’ actively and have greatly contributed to modernism. This study will help us to understand the diversity of design since modernism, by comparing these two designers' furniture design. It also covers the common factors In modern furniture design, and analyses their individuality and likeness In design. The following is a comparison of furniture design by Le Corbusier and Alvar Aalto. Le Courbusier linked International design and Aalto linked Rational design and Organic concept design to their furniture, just as they did in their architecture. They were able to establish the base of modern furniture design by adapting new concepts and pursuing humanism. In structure, Le Corbusier's furniture Is simple and proportional. It demonstrates a sophisticated geometric composition, mechanical beauty. On the other hand, Aalto rationally linked nature with human requirements and his furniture is organic and in harmony with geometric structure. In function, Le Corbusier's furniture is standardized and prefabricated. He designed for the user so they could choose to use the furniture efficiently to suit their needs. In comparison with Le Corbusier, Aalto Invented the ‘Stacking Chair’ which allows a more effective use of space and reflected the structure of the human body to improve the user's comfort. In materials and techniques, Le Corbusier used new materials like metal or leather, and attempted new ways such as welding, prefabrication, and standardization for production. On the contrary, Alto mainly used birch, which is the traditional material in Finland, and tried new bent wood techniques and joining methods.
