  • The modeling of uplift pressure within dam, on the foundation on which it was constructed, and on the interface between the dam and foundation is a critical aspect in the analysis of concrete gravity dams, i.e. crack stability in concrete dam can correctly be predicted when uplift pressures are accurately modelled. Current models consider a uniform uplift distribution, but recent experimental results show that it varies along the crack faces and the procedures for modeling uplift pressures are well established for the traditional hand-calculation methods, but this is not the case for finite element (FE) analysis. In large structures, such as dams, because of smaller size of the fracture process zone with respect to the structure size, limited errors should occur under the assumptions of linear elastic fracture mechanics (LEFM). In this paper, the fracture behaviour of concrete gravity dams mainly subjected to uplift Pressure at the crack face was studied. Triangular type, trapezoidal type and parabolic type distribution of the uplift pressure including uniform type were considered in case of evaluating stress intensity factor by surface integral method. The effects of body forces, overtopping pressures are also considered and a parametric study of gravity dams under the assumption of LEFM is performed.

  • To clarify functionality of depolymerized alginate obtained by hydrolysis of alginate through a heating process at $121^{\circ}C$ on gastrointestinal physiology, the effects of a depolymerized alginate on fecal microflora and the intestinal environment were studied in rats. Rats were fed with diets containing 1, 5 and $10\%$ of each depolymerized alginate (HAG-10, HAG-50 and HAG-100) and alginate for 35 days, Among 20 species of authentic intestinal bacteria, Bacteroides ovatus showed the abilities to ferment HAG-10 HAG-50, HAG-100 and alginate, The 1, 5 and $10\%$ of HAG-50 and $1\%$ of alginate diets resulted in the increased ratio of Bifidobacterium and Lactobacillus to total bacteria, while the 5 and $10\%$ alginate diets decreased in feces of rats, significantly (p<0.01). These results suggested that $5\%$ HAG-50 diets contribute to an improvement of intestinal microflora in rats.

  • Purpose: To evaluate shoulder stability, clinical, and functional results more than 6 months after utilizing the 'Remplissage' technique, consisting of an arthroscopic posterior capsulodesis and infraspinatus tenodesis, to fill Hill-Sachs lesions. Materials and Methods: Seven patients were followed-up more than 6 months after the 'Remplissage' procedures performed in our hospital from August 2008 to August 2009. The mean age of the patients was 28.6 years and the mean follow-up time was 10 months. Evaluations included ROM, ASES score, KSSI score, ROWE score, and postoperative MRI. Results: In a functional evaluation of the patients with an average postoperative time of 10 months, the ASES score improved from 51.4 preoperatively to 76.8 postoperatively, the KSSI score improved from 46.5 preoperatively to 76 postoperatively, and the ROWE score improved from 43.5 preoperatively to 76.3 postoperatively. After an average postoperative time of 10 months, the range of motion was nearly normal (>170 degrees in further flexion, and >45 degrees in external rotation). Conclusion: In recurrent shoulder instabilities with large Hill-Sachs lesions, the 'Remplissage' technique resulted in good outcomes in terms of shoulder stability, clinical, and functional results after postoperative times of more than 6 months.

  • Listeria monocrogenes has been increasingly recognized as an important food poisoning and pathogenic bacterium which is Gram positive, non spore forming and facultative anaerobic rod shape. Bacteriological and physiological characterization of L. monocytogenes YM-7 isolated from a patient was performed. Optimum growth condition of 1. monocytogenes YM-7 was at $37^{\circ}$, pH 8.0 and $0\%$ sodium chloride in tryptic soy broth, and then it grew pretty well in the range of $8-40^{\circ}C,\;pH 5.0-10.0\;and\;up\;to\;7\%$ of sodium chloride in the medium. The highest hemolysin activity of hemolysin produced by L. monocytogenes YM-7 was shown in the stationary phase of its growth. Hemolysin produced by the isolated strain was stable at $4^{\circ}C\;and\;pH\;6.0-8.0, while it was gradually unstable by increasing the storage temperature.

  • User movement is an important factor in determining the amount of the acquired knowledge and information about space contexts. A reasonable circulation plan affects the spatial usage, space revitalization, and activity satisfaction, and is ultimately a means to increase spatial usefulness. On the other hand, a disorderly circulation system causes negative experiences due to difficulties in wayfinding. This research identified the importance of a pedestrian circulation system analyzing the correlation between the spatial configuration index and pedestrian movement, and visitors' movement in the leisure space by using Space Syntax. The research area, Ouam-ri, where numerous guests visit this designated folk village, is a typical case in which a settlement space is used as a leisure space. There was a great deal of risk that visitors would get lost while wandering through the space. Also, it is difficult to induce visitors to tour economically even though the pedestrian circulation configuration of Ouam-ri forms the natural moving line because of its typical tree structure. Additionally adjusting and to supplementing the pedestrian system is required in order for the traditional village, a settlement space, to be used as a leisure space.

  • Background & Method : Bronchiolitis obliterans organizing pneumonia(BOOP) is a specific clinicopathologic condition characterized by chronic inflammatory interstitial infiltrates. Cryptogenic form of BOOP presents subacute clinical course of flu-like illness, such as cough, fever, dyspnea with exertion and other constitutional symptoms. Pathologically it shows the presence of granulation tissue filling the lumen of terminal and respiratory bronchioles, extending into distal airspaces. Recently, we reviewed 24 cases of idiopathic type of BOOP, 5 cases of our hospital and another 19 cases on Korean literatures, and compared with reviewed data from foreign literatures. Results : Mean age was 54 years old and there was female preponderance in domestic reports. Their common presenting symptoms were dyspnea and cough, and mean duration of illness was 41 days. On chest examination, inspiratory crackle was a common finding. The laboratory findings were nonspecific except hypoxemia. Lung function studies revealed restrictive defect or combined obstructive and restrictive pattern in most patients. Bilateral patchy and nonsegmental alveolar opacities constituted characterized radiographic finding, highlighted on high resolution computed tomogram. It showed a favorable prognosis with an excellent responsiveness to corticosteroid therapy. The clinical features and laboratory findings were similar between domestic and foreign cases except female preponderance in Korean cases. Conclusion : If the clinical course is atypical or pregressive under proper treatment, clinicians should reevaluate clinical features and radiographic findings under the consideration of BOOP. Tissue confirmation would be recommended for the definitive diagnosis of BOOP.

  • The general tendency of approach to Korean Design History has been focusing its primary interest on the grand story in relation to the problems of modernization in political, economical and social aspects of Korea. In the discourse of modernization, however, there are two sides immanent in the modernization: there is the formal, institutional and authoritative modernization developed inside the capitalistic mode of production and the informal, individual and cultural modernization manifested in the mode of everyday lives. Especially, despite the viewpoint of the latter being embossed as an alternative approach in various areas including the academic world of history since the collapse of socialism, the historical recognition of the phenomena of modern design by the Korean design historians is more like the 'history from the above' that exists at the level of the discourse outside the reality rather than the 'history from the below' that exists within the ordinary life. To grant a sense of balance in such frame of historical understanding, it requires the restructuring the design history of Korea through the cultural perspectives from having the representation of mundane lives realized by the voluntary design activity of the common people as research subjects. One of the methods to acquire an answer to such problem is decoding, in the manner of 'cultural history', the life-long domestic artifact made by Madame Yang, Gap Jo (currently 87 years of age) who is a model of typical Korean mother. Through the historical rumination on the traces of unpretentious lives of the people that has been buried under the grand narrative of the Korean Design History, a new era aimed for the historical prospect of Korean design as cultural history will be possible by excavating the petit yet multi-layered meaning of Korean designs.

  • In this paper, a new low power 16-bit ALU has been designed, fabricated and tested at the transistor level. The designed ALU performs 16 instructions and has a two-stage pipelined architecture. For the reduction of switched capacitance, the ELM adder of the proposed ALU is inactive while the logical operation is performed and P(propagation) block has a dual bus architecture. A new efficient P and G(generation) blocks are also proposed for the above ALU architecture. ELM adder, double-edge triggered register and the combination of logic style are used for low power consumption as well. As a result of simulations, the proposed architecture shows better power efficient than conventional architecture$^{[1,2]}$ as the number of logic operation to be performed is increased over that of arithmetic to logic operation to be performed is 7 to 3, compared to conventional architecture. The proposed ALU was fabricated with 0.6${\mu}m$ single-poly triple-metal CMOS process. As a result of chip test, the maximum operating frequency is 53MHz and power consumption is 33mW at 50MHz, 3.3V.

  • 21세기를 맞이하여 대학도서관은 정보기술의 도입, 업무내용의 변화, 이용자의 요구변화등 급격하게 변화하는 새로운 환경에 직면해 있다. 본 연구는 한국의 대학도서관 조직구조의 현황에 대한 분석과 함께 다양한 조직이론들과 정보환경의 변화에 기초해서 도서관조직을 활성화시키기위한 개념적인 조직모델을 제시하고자 한다. 한국의 대학도서관은 거의 10년동안 법적인 제약과 조직내외의 환경적인 한계 등으로 인해 전산화시스템의 도입, 도서관부관장의 임명, 그리고 도서관과 컴퓨터 센터와의 통합시도와 같은 약간의 변화외에는 거의 변화가 없었다. 전형적인 한국의 대학도서관은 수서, 기술서비스, 열람과 참고봉사 부문으로 조직되었다. 여기서 수서 기능을 기술서비스의 부문으로 간주한다면, 본 연구의 대상인 대학도서관 114개관 중 95개관(82.5%)이 전통적인 도서관조직의 형태인 기술서비스와 공공서비스 부문으로 조직된 것으로 나타났다. 본 연구에서는 전통적인 도서관조직의 문제점들을 급복할 수 있는 21세기의 개념적인 대학도서관 조직모델로서, 네가지 부문 - 서비스 부문, 서비스지원 부문, 기술지원 부문, 그리고 통합·조정부문-을 대학도서관의 개념적인 기본 구성요소로써 제안하였다. 그러나 모든 도서관의 서비스나 업무과정에 대해 적합한 잉상적인 조직구조는 없으며, 조직의 재조직과정은 도서관의 형태와 목적, 업무과정에 따라 매우 다양하다. 따라서 도서관의 재조직화는 환경의 변화에 따라 끊임없는 과정이 될 것이며, 도서관조직의 성공은 이러한 변화에 적응할 수 있는 개인과 조직의 역량에 달려있다고 하겠다.대한 순서에 있어서 차이가 있다. 4) 도서관에 대한 태도에 있어서 두 집단은 상이한 입장을 보이고 있다. 학자들의 과반수는 중요 정보원으로서 자신의 개인장서를 활용하며, 도서관의 장서 및 그 조직방법에 대해서도 별로 만족하지를 못하고 있다. 반면에, 실무가들은 도서관에 대하여 비교적 만족하며 따라서 도서관에 대한 이용도도 높다. 5) 두 집단 모두 보조인을 적극적으로 활용하지 않으며 사서의 도움을 받는 경우도 극소수에 불과하다. 이러한 조사결과를 기초로 하여 볼 때 법률전문직을 둘러싼 정보환경을 개선하기 위하여는, 인쇄된 일차적 정보자료의 검색방법등을 개선하고, 나아가서는 법령과 판례정보를 위한 효율적인 시스템을 구축하며, 뿐만 아니라 이용자의 요구에 충분히 대처할 수 잇는 도서관으로 변화되는 것이다. 이와 함께 가장 중요한 것은 법과대학과 사법연수원에서 법학 연구방법에 관한 강좌를 개설하여 각종 법률정보원의 활용 내지 도서관 이용방법에 관하여 교육하는 것이다.글을 연구하고, 그 결과에 의존하여서 우리의 실제의 생활에 사용하는 $\boxDr$한국어사전$\boxUl$등을 만드는 과정에서, 어떤 의미에서 실험되었다고 말할 수가 있는 언어과학의 연구의 결과에 의존하여서 수행되는 철학적인 작업이다. 여기에서는 하나의 철학적인 연구의 시작으로 받아들여지는 이 의미분석의 문제를 반성하여 본다. 것이 필요하다고 사료된다.크기에 의존하며, 또한 이러한 영향은 $(Ti_{1-x}AI_{x})N$ 피막에 존재하는 AI의 함량이 높고, 초기에
