        李庸一,宋永珏,金昌協,李尙桂 최신의학사 1967 最新醫學 Vol.10 No.12

        14 years old male ooy was consulted to Han-11 hospital on Feb. 26, 1964 because of productive coughing, exertional dyspnea and general weakness with following history. He was normal full term. The neonatal period was uneventful. He suffered from measles at the age of 6 months. Since 2 years of his age, he had been frequently suffered from respiratory infection and diagnosed as a case of bronchitis or bronchopneumonia. Physical examination revealed emaciation, pigeon chest and dry or moist rales on both lung field on auscultation. There was leucocytosis. Throat swab and sputum culture was negative for A. F. B. or other pathogenic organisms. Mantoux test and skin test for P.W. and C.S. were also negative. Chest x-ray revealed multiple thin walled cysts which scattered over right entire lung field and left lower lung field. Successive chest X-ray taken 3 years later was checked on April 27, 1967 which showed almost same findings comparing with preveousfilm. Review of Iiterature as for cyst of the lung was made briefly.

        영아의 경부 이소성 흉선의 초음파와 CT소견:1예 보고

        이용일 대한영상의학회 1998 대한영상의학회지 Vol.38 No.1

        2개월된 남자 환아의 좌측 악하선 하방에서 생긴 이소성 흉선의 1예를 보고한다. 초음파와 CT소견상 흉쇄유돌근의 전 내방과 악하선 후방에 좌측 경동맥초의 전 외측을 따라 경계가 좋은, 분엽이 된 3$\times$2cm의 고형종괴가 보였다. CT소견상 경부 종괴는 전종격동에 있는 정상 흉선의 CT감쇄계수와 유사하였다. 영아에서 경동맥초를 따라 생긴 종괴가 있을 때, 경부 종괴의 원인으로 드물지만 이소성 흉선을 감별해야 한다. We report a case of ectopic thymus in the left submandibular area of a two-month-old boy. On US and CT scans,a well-marginated, 3$\times$2cm-sized solid mass along the left carotid sheath, anteromedial to the sternocleidomastoidmuscle and posterior to the submandibular gland, was seen. CT attenuation of the mass showed that it was similarto that of normal thymus in the anterior mediastinum. Although a rare disease, ectopic thymus should be includedin the differential diagnosis of cervical masses along the carotid sheath in infants.

      • 유비쿼터스 RFID 기술 분석

        이용일 慶北專門大學 (영주경상전문대학) 2008 慶北專門大學 論文集 Vol.26 No.-

        In short, just as Information Revolution is to put physical space into computers, so Ubiquitous Revolution is to put computers into physical space. I suggested RFID technology in the Ubiquitous world. Ubiquitous model is to combine e-Learning model and traditional face-to-face learning model in the third space of Ubiquitous, create educational environment where learners learn anytime, anywhere, through any device, and lead learners to concentrate on their learning activities. "Ubiquitous" is aimed at building a world where time and space are combined and everything is connected so as to overcome the temporal and spatial limits by removing the border between electronic space and physical space, and limitation to rationality that has constantly plagued human beings can be overcome through exchanging the latest and realtime information. Ubiquitous, containing values of human beings naturally seek, sets its goal as 5Anys (Anytime, Anywhere, Anynetwork, Anydevice and Anyservice) of 5Cs (Computing, Communication, Connectivity, Contents and Calm). This study is centering on the educational environment of Ubiquitous Era, especially university campus. I also investigated ubiquitous computing strategies worldwide, suggestions for driving major projects and ways to apply ubiquitous core RFID technology to the education.

        Settlements in Korean rural society are the product of many historical changes. Furthermore, in recent years national development planns as a whole and many measures to promote the development of the rural economy are major factors which change rapidly the pattern and structure of rural villages as well as the population composition. This change means that the original landscape and form of the villages are gradually disappearing modifying to adjust for a new economic system and modern culture. In this process, we are urgently need to preserve and study the basic structure and pattern of rural settlements in areas where these changes have not yet had much effect. Thus, this study leads to several different questions. The first question is to identify the spatial pattern of rural settlements which might be related to the land form, cultivated field systems, roads, and accessibility of neighbour settlements. The second question is what major locational factors have contributed to the forming rural village. Finally, the study focuses on the internal spatial structure of the village in terms of the arrangement of housing and other facilities, housing structure, and the composition of the residents. For data collection and survey, field trips and interviews were conducted many times during last two years. At the same time, a mapping analysis of land use and various appropriate techniques were employed in this study. Generally the villages investigated in the Yongchon basin represented a functionally agricultural character closely related to the nearby location of arable lands. The type of settlement, like most of Korean nuclear settlements, shows the agglomeration pattern which is composed of houses ranging in number from 21 units to 61 units. Also the critical distance between out-reaching farming from the center of the villages to far parcel of farming land owned by the individual farmer turned out to be 1.2∼1.4km. Just outside this critical distance, the ownership of land tended to decline rapidly. However, the average distance from farmer's house to farmland per farming household in a sample survey was measured as 5401n. Besides the availability of arable land in Yongchon basin, the traditional geomancy, the natural advantage of landform; like hillside areas and small valleys, ($quot;gol(골)$quot; in Korean) in south-east direction, and accessibility are identified a major multiple forces which decide the location of individual village. Internal structure of each village seems to emerge as a natural process of growth showing the evolution of an irregular road pattern. One or two retail stores, a farm warehouse, a village hall, and small size mill are major functional service units for each village at the minimum level of threshold. Inside the village, the residential differentiation based on the clan family was observed. The shrine of a tutelary deity(성황당) and a building for virtuous woman(열녀각) made up as an important element of the internal structure. Along these lines, we can understand the basic formation and pattern of rural settlement to a certain degree even if the study area might be locally limitted.

      • Potts 뉴럴네트워크의 자기조직화에 대한 연구

        이용일 慶北專門大學(영주경상전문대학) 2000 慶北專門大學 論文集 Vol.18 No.-

        This paper present an approach to new algorithms on the basis of a Potts neural network for coherent mapping, and we remodel the Durbin algorithm and the Kohonen algorithm with mean field annealing. The nearby elements in the parameter space are orbed as similarly as possible on the cortex-like map, and the objective function costs between neighboring cortical points are as smooth as possible. Moreever, we show a theoretical approach and simulation to developing self-organizing algorithms with a novel decision principle for competitive learning.

        Since deregulation on airline the cost of air travel in The World Airline Market has fallen and the size of the airline industry has grown rapidly. Therefore, the low cost carrier has become the new choice for travelers since 1990s in US and has become more favourite on Europe, East-Asia bound in early 2000. This analysis will examine the current structure of the the world airline industry. The world airline market is changing as we see trends low-cost carrier and a custumer's demand for greater of the airline industry flexibility. The emerging significance of the low-cost carrier may indicate a shift in the structure of the airline market. The lower cost structure can be guantified by aggregating the cost saving of point to point networks, wage saving, and operating from not providing air routing service. Therefore, this paper will describe the meaning of a low cost carrier and the fundamental concepts for such a carrier. Moreover, it also will show some experience from the world low cost carrier.
