In this study, we report a new record of the clustered bur-reed Sparganium glomeratum (Laest. ex Beurl.) Beurl., from Yongneup Moor of Daeamsan Mt. in Gangwon-do, Korea. This species is distributed in the cool temperate and circumboreal regions of the Northern Hemisphere. As we recorded this species in a high-altitude wetland, we named it "Du-me-heuk-sam-neung" after the Korean word that translates to "Sparganium found in deep mountains." We provide descriptions of the morphological characteristics, photographs, and detailed illustrations of S. glomeratum, as well as a key to allied taxa in Korea.

In stenosis of a segmental branch or among multiple renal arteries, Doppler sampling of intrarenal arteries in the upper, mid and lower poles demonstrates strikingly different waveform patterns that might otherwise be overlooked. We report a case of segmental branch renal artery stenosis in which a pulsus parvus et tardus waveform was observed in a segmental branch of a renal artery. In this case, systematic analysis of Doppler waveforms of intrarenal arteries at more than three different locations facilitated a rapid and confident diagnosis of segmental branch renal artery stenosis.

Onions are a significant crop in Korea, and cultivation is increasing every year along with high demand. Onions are planted in the fall and mainly harvested in June, the rainy season, therefore, physiological changes in onion bulbs during long-term storage might have happened. Onions are stored in cold room and at adequate relative humidity to avoid quality loss. In this study, bio-yield stress and weight loss were measured as the quality parameters of net packaged onions during 10 weeks of storage, and the storage environmental conditions are monitored using sensor networks systems. Quality estimation of net packaged onion during storage was performed using the storage environmental condition data through machine learning approaches. Among the suggested estimation models, support vector regression method showed the best accuracy for the quality estimation of net packaged onions.

Exendin-4 (Ex-4), a peptide secreted from the salivary glands of the Gila monster lizard, can increase pancreatic $\beta$-cell growth and insulin secretion by activating glucagon-like peptide-1 receptor. In this study, we expressed a fusion protein consisting of exendin-4 and the human immunoglobulin heavy chain (Ex-4/IgG-Fc) in E. coli and explored its potential therapeutic use for the treatment of insulin-resistant type 2 diabetes. Here, we show that the Ex-4/IgG-Fc fusion protein induces expression of insulin receptor substrate-2 in rat insulinoma INS-1 cells. Our findings therefore suggest that Ex-4/IgG-Fc overexpressed in E. coli could be used as a potential, long-acting glucagon-like peptide-1 mimetic.

This paper presents the way of building an occupancy grid map which a mobile robot needs to autonomously navigate in the unknown environment. A disparity map resulting from stereo matching can be converted into the 2D distance information. If the stereo matching has some errors, however, the subsequent map becomes unreliable. In this paper, a new morphological filter is proposed to reject 'spikes' of the disparity map due to stereo mismatch by considering the fact that these spikes occur locally. The new method has advantages that it is simpler and more easily realized than existing similar algorithms. Several occupancy grid maps based on stereo vision using the proposed algorithm have been built and compared with the actual distance information to verify the validity of the proposed method.

절연파괴 강도에대한 특성분석을 위해 와이블 plot을 이용하였다. ENMMC에서 실란처리와 미처리특성에서 실란처리된 결과 형상파라미터가 상대적으로 높은 값을 나타내었다. 이는 절연파괴결과가 균질함을 분명하게 나타낸 결과이다. 또한 스케일파리미터에서도 처리된 결과가 상대적으로 높은 결과를 보이고 있다. 나노입자 충진함량에 대한 효과에서도 체적비로 6.2vol%가 24.87vol%보다 월등하게 높은 형상파리미터와 스케일 파리미터를 나타내었다. 현장에서는 B10의 수명이 누적확률(63.2%)보다 오히려 유효한 평가자료 라고 사료된다. 역시 실란처리 된 결과가 미처리된 것에 비하여 그리고 나노입자 충진함량이 적을수록 높은 결과를 나타내었다. 이로서 중전기기 산업절연재료로서 향후 전망을 크게 할 것으로 본다.

Lower lip reconstruction in cases with a full-thickness defect over one-third of the vermilion is challenging. Numerous conventional techniques have been applied with unsatisfactory surgical outcomes because of microstomia and oral commissure blunting due to shortened horizontal lip length. Herein, we present a case in which a full-thickness lower lip defect of more than one-third of the horizontal lip length was covered with a novel mucosal roofing flap reconstruction to minimize the loss of horizontal lip length and to preserve mouth opening. No recurrences or metastases were observed during 3 years and 6 months of follow-up, with horizontal lower lip length maintained and mouth opening of 2.5 finger breadths.

Purpose: The early churches such as tabernacle, temple and synagogue had played a important role to form space concepts of western churches. Tabernacle and temple were designed with vertical axis which consisted of sanctuary, sanctum, outdoor yard. Synagogue was designed pew of congregation around pulpit to give a sermon. The aim of this paper is to analyze spatial principles of churches designed with vertical axis and centralized plan. Method: The concept of vertical axis plan succeeded to Basilica, Romanesque and Gothic churches, and the concept of centralized plan succeeded to Byzantine and Renaissance churches. Therefore, this paper analyzed spatial characteristics and role of light in churches according to epoch, and was progressed by examining the existing researches and case studies. Result: The churches designed with vertical axis plan realized spatial composition to show the concept of domus dei, and worship space was illuminated with mysterious light. The churches designed with centralized plan realized spatial composition to show the concept of domus ecclesiae, and light created dramatic holiness in worship space.

Purpose: This paper tried to understand the architectural concept of Neo Corbusian architects who had succeed to the Le Corbusier's principles of modern architecture and developed into their own creative architecture and formed a big achievement in the contemporary architecture. As representative Neo Corbusian architects, Henri Cirianni, Alvaro Siza and Laurant Beaudouin were selected to study their own design concepts and principles. Method: Three step study was conducted for the paper; Firstly, investigated significant differences about modern architecture between Le Corbusier and three neo corbusian architects; Secondly, analyzed the architectural meanings of 'Plan Libre' and 'Promenade Architecture' of three neo corbusian compared to Le Corbusier's ones; Finally, deducted their own design process to integrate the architectural concept of 'Plan Libre', 'Promenade Architecture' and 'Natural Light into architectural design. Results: According to the results of the research, Henri Cirianni, Alvaro Siza and Laurant Beaudouin made a splendid progress of Corbusier's modern concept, and then, created his own originative architecture by combining Plan Libre', 'Promenade Architecture' and 'Natural Light.

Purpose: The concept of the tectonic has researched to find out the identify of modern architecture. The meaning of traditional tectonic knowledge to emphasize structural joints and attention to detail in creativity has developed in various ways in contemporary architecture. The purpose of this study is to analyze the tectonic characteristics and architectural expressions of the light appeared in the works of Santiago Calatrava. Major features in his works could be found is to maximize structural beauties through deducing the architectural images from the nature and expressing the material properties and the kinetic structures, and thus, to ultimately create the functional space and form by connecting the light to the tectonic structure. Method: Accordingly, I tried to analyze the three works of Santiago Calatrava (the Milwaukee Art Museum, the Bodegas Ysios Winery and the City and Arts and Sciences) as following categories - the structural aesthetics, the expression of material properties, the relationship between he kinetic structures and the light. Result: According to the results of the study, Santiago Calatrava tried to create his own architectural aesthetic by combining structural tectonic with nature, material, regional place and culture. He also sought to express the tense and dynamic tectonic rather than the stable one in his works.
