전문용어의 수가 급증하면서 전문용어를 자동으로 인식하는 연구가 활발히 진행되고 있다. 전문용어를 인식하기 위해서 전문용어의 범위를 정한 뒤 그 전문용어의 분야를 선택해야 한다. 본 논문에서는 생물/의학 사전정보와 CRF(Conditional Random Fields) 기계학습 기법을 사용하여 연구를 진행한다. 기계학습을 위한 자질로 품사, 접사, 대소문자, 숫자, 특수문자, 단서어휘 등을 사용한다. 특히 단서어휘와 사전정보를 중요한 요소로 생각하여, 3가지 방법으로 나누어 실험한다. 총 분야의 개수는 7개이며, 각 분야별로 정확률, 재현율, F-measure를 측정한다. 경계인식은 83.92%의 정확률, 96.42%의 재현율, 89.73의 F-measure가 결과로 나타났고, 분야분류는 79.29%의 정확률, 91.06%의 재현율, 84.77%의 F-measure가 결과로 나타났다.

The purpose of this study was to concentrate on macroscopic discussion about how the recurrence of actual case in move is accepted ideologically. When considering the characteristic that non-visual factors are embodied when movie image reflects a certain target, the issue of recurrence has always caused discussion. Regardless of its independence or dependence, one individual's experience can be similar to sensual recognition but it can't be identical. Therefore, 'the truth recurred by movie' can't be real 'truth'. When director expresses the target, the aesthetic intention gives an effect to audience's emotion and recognition, Therefore, the study tries to review whether the movie truth drawn by movie can reach the possibility of epistemology agreement.

In this paper, a new integral imaging method with horizontal parallax only is proposed by modified use of elemental images pickuped from conventional integral imaging. The modified elemental images are obtained by magnifying single horizontal elemental image vertically and from which 3D images could be reconstructed. The proposed method can provide us large reduction of transmission information data for elemental images by eliminating the vertical parallax. The feasibility of our approach is experimentally demonstrated and its results are presented.

경계면 요소를 이용하여 철근콘크리트 구조물의 접촉면 문제를 유한 요소법으로 해석하는 기법에 대하여 연구한다. 본 연구에서는 경계면 요소의 수치해석의 이론과정을 전개하고, 실험 관찰된 부착 시험체에 적용하여 이형철근과 콘크리트 부착기구의 접촉면을 해석한다. 경계면은 특별한 연결요소를 이용하여 재현하며 Mohr-Coulomb의 마찰 이론을 응응한다. 해석의 주요점으로 하중상태에 따라 변화되는 경계면의 접촉상태, 즉 고정(stick), 미끄러짐(slide), 분리(separation)를 묘사하여 경계면 재료의 비선형 거동을 관찰한다. 부착모델의 해석결과는 실험실의 결과와 대체로 일치되며 따라서 철근콘크리트 접촉면의 응력해석을 위해 경계면 요소가 활용될 수 있음을 보여준다.

Eupseong (county seat) represents the Korean historic city which had constructed intentionally by central government during Joseon Dynasty. There were variety of government or county offices which named as Gaeksa, Dongheon, Nea, Jilcheong, and so on. Also, there are houses of the people in many Eupseong but not all of them. This study aims to reconstruct the landscape elements and its overall construction of Eupseong in the Late Joseon dynasty on the original land registration map(1913). For this purpose, the author underlines to set-up target period for reconstruction. This study considers the early 19th century in Joseon as completion period of Eupseong landscape, and then researches distribution of Eupseong and major elements of its landscape in national scale. Based on those results, the author tries to reconstruct location of major landscape elements and layout of Eupseong landscape in the early 19th century on the original land registration map in case of Taean Eupseong, Seosan Eupseong, and Haemi Eupseong in Chungcheongnam-do (province), Korea.

XML 문서의 요소는 의미적인 정보와 트리기반의 구조적인 정보를 포함하고 있기 때문에 요소의 구조적인 유사성이 곧 XML 문서의 유사성으로 연구되어 왔다. 그러나 구조적이고 순차적인 유사성만을 고려한 순차패턴 유사성 검색 방법은 의미적인(sementic) 유사성을 제대로 반영을 할 수가 없다. 이것은 정보 검색에 있어 재현율(recall)을 낮을 수밖에 없는 원인을 제공한다. 따라서 본 논문에서는 기존에 사용되었던 순차패턴을 기반으로 한 유사성의 계산 방법과 각각의 연구 방법이 의미적인 유사성에 대하여 한계가 있음을 찾아보았다.

각종 하천 정비, 개발 등의 사업의 증가와 함께 홍수 등 자연재해의 취약지점으로 주목 받고 있는 하천 합류점에 대한 관심도 높아 가고 있다. 본 논문에서는 특히 자유 수면의 재현을 위하여 3차원 유한요소법 기반의 레블셋 기법을 이용하여 합류부의 수리 특성을 모의하였다. Navier-Stokes 방정식의 공간차분에는 Characteristic Galerkin 기법을, 시간차분에는 Fractional Four-step 기법을 적용하였다. 상류와 사류 상태 모두에 대하여 실험 결과에 근접하는 좋은 결과를 얻을 수 있었다.

Sled test id widely used to evaluate the performance of occupant's safety system in frontal crash environment without having to conduct a full-scale crash test. Steel bar breaking system is used to generate deceleration profile which is experienced by passengers in frontal crash. In this study, deformation analyses of steel bars were conducted using a commercial FE code. Several guidelines were proposed to improve the accuracy of simulation.

The main purpose of this study is to examine how place representation is related to the formation of urban parks in Seoul, which began at the end of the 19th century. In order to grasp place representation, the hypothesis of this study is that most urban parks are undertaken with the idea of monumentality and symbolism or memories of the place itself. Diverse ways of representation through physical or non-physical aspects of symbolism, monumentality, and place memory are summarized as follows. First, in the case of the physical aspects of representation in the parks, monumentality and symbolism are expressed mostly through monuments or statues. In the case that the intention of the park is commemorative, celebrative elements are more actively utilized. In other cases, symbolic sculptures or statues, which are randomly designated by the government, are so often used regardless of the overarching concept of the urban park. In addition, in the case of place memory, monumentality or symbolism are commonly represented through bronze statues or partial remnants of the past. Recently, however, the site in itself has been constructed to coordinate the memories of a certain place into the configuration of the park. Secondly, in relation to the non-physical representation elements, many urban parks tend to reveal monumentality or symbolism through the names they are given. Recently, this tendency has significantly dropped, but some places of parksare frequently denominated in consideration of place memory. In the case of events held in parks, parks which were constructed in the beginning of the park movement, such as Tapgol Park, hold certain events to commemorate certain causes that took place in those days. On the other hand, the main purpose of recently-constructed urban parks relating to place memory is to encourage citizens to participate in events in a variety of ways.
