상완골 원위부 과간 골절은 소아에서는 매우 드물게 발생되는 골절로 대부분 주관절의 굴곡상태로 주관절 후방부에 직접적인 충격에 의해 발생하는 것으로 보고되고 있다. 전위가 없거나 경미한 경우 도수적 정복술 혹은 도수적 정복술 후 경피적 핀고정술을 시행하며, 전위가 심한 골절이거나 도수적 정복술이 불가능한 경우 관혈적 정복술 후 핀고정술을 시행하는 것으로 알려져 있다. 저자들은 전위된 상완골 원위부 과간 골절 환아 2예에서 각각 도수적 정복술과 관혈적 정복술 후 K 강선 고정술을 시행하여 만족한 결과를 얻었기에 보고하는 바이다. Intercondylar fractures of the distal humerus are very rare in children. The pattern of the fracture would suggest that the mechanism of injury involves a fall directly on the flexed elbow. Most agree that the undisplaced fracture can be managed conservatively. With increasing displacement and comminution, the opinions tend to differ. We suggest that closed reduction with percutaneous K wire pinning and open reduction with percutaneous K wire pinning offer a satisfactory methods by which to treat displaced intercondylar fracture in children.

To lessen the ratio of under achievers is one of the most urgent task which recent school mathematics education is confronted with. To cope with this problem efficiently, math. teachers should know more specifically and concretely the causes that make the students dislike mathematics. But actually, there are too many reasons for these situations. So, in this paper, we tried to devise a tool to analyze and measure each student's math. disliking status. We proceeded this research via the following procedures. 1. Grasping the causes which make the students dislike mathematics as specifically as possible. To obtain this, we asked more than 300 of secondary school students to write down their thoughts about school mathematics. 2. Analyzing the responses, we abstracted 74 numbers of items which were supposed to be the causes for secondary school students' mathematics disliking. 3. With these items we made a test to measure students' aptitude for each item. 4. With this test paper, we tested over 800 of secondary school students. Through factor analysis and theoretical argument, we categorized the 74 items into 11 groups whose names were defined as factors of mathematics disliking. 5. For each of these 11 factors, we developed a norm which could serve as standard of comparison in measuring each student's mathematics disliking status. Using this tool teachers were able to describe each student's traits of mathematics disliking more specifically.

본 논문에서는 인간의 평활 추적안구운동을 모방하는 능동시각시스템(active vision system)을 구현하였다. 평활 추적 안구운동을 모방하는 능동시각시스템을 구현하기 위해 인간의 안구운동 중에 관찰되는 신경생리학적인 특징들을 이해하고, 다양한 안구운동 중에서 평활 추적안구운동 중에 관찰되는 중측관자(medial temporal) 세포의 역할을 자기조직화 형상지도(self-organizing feature map)와 승자독점(winner take all)을 이용하여 구현하였다. 회전속도계 궤환 모델(tachometer feedback model)로 중상측관자(medial superior temporal) 세포의 역할을 모델하였다. 그리고 인공망막칩으로 인공 안구를 구성하고 형상기억합금 구동기(actuator)를 이용하여 인공 안근육을 구성하여, 빛의 밝기 변화인 윤곽(edge) 정보에 반응하는 인공 안구모형을 제작하였으며, 실험을 통하여 시스템의 동작성능을 보였다. In this paper, we proposed a model of smooth pursuit eye movement, and developed a human-like active vision system using a retina chip and a shape memory alloy actuator. The model of smooth pursuit eye movement is to imitate the role of MT and MST area of human brain in smooth pursuit eye movements. We fabricated the 8×8 retina chip for the edge detection. The developed retina chip is an image sensor to extract edge information and the shape memory alloy actuator is a driver to imitate the role of eye muscles to follow a moving object.

CuInSe₂ thin films were prepared on Si(100) wafer by RF magnetron sputtering from powder target which was prepared by reacting high purity Cu₂Se and In₂Se₃(99.999%, Cu₂Se: In₂Se₃=1:1 mole ratio), in argon gas The XRD results suggest that deposited thin films were mainly composed of crystalline CuInSe₂ with the typical chalcopyrite structure, whereas film deposited showed the mixed phase of Cu₂Se+CuInSe₂at 50W. Deposited film showed (204), (220) preferred orientation at 50W and deposited films from 75W were strongly oriented along th e(112) plane. In the EDS analysis, Cu/In mole ratio of the thin films was decreased and Se/(Cu+In) mole ratio was increased with increasing RF power. The lattice parameters of a, c axis and c/a ratio of deposited films were decreased with increasing RF power. The grain size of the thin films measured by SEM became coarse with the increase of RF power.

Web mining is to extract useful information for homepage management by analyzing the structures, contents and usages of web pages. The web mining is classified into structure mining, content mining and usage mining. Web crawler is a representative tool that has been used in the structure mining. Not only the web crawler has a function to analyze the link structures among webpages and accumulate information, but also it is used to resolve problems by finding out link errors on homepages. But this web crawler uses a way of analyzing based on texts, so it takes so much time and costs a lot to find out locations of errors. As a result, most of homepages just leave these link errors unsettled. In this paper, we design and implement an analyzing system of link errors on hyperlinked environment in order to improve defects and increase efficiency of links on homepages. In addition, this system which we propose analyzes the location and size of hyperlinks, and provides visual information whether a link is successfully connected or not.

Grid computing is an emerging technology that promise to unify resources and computing power in many organizations together. It couples a wide variety of geographically distributed computational resources, and presents them as a unified integrated high-end computer. The Globus Resource Allocation and Management(GRAM) service provides for the management and remote execution of jobs defined using a standard Resource Specification Language(RSL) requested by client in grid environment. However, Currently the GRAM has very limited functionality to support for applications that required special execution environment. Here, we provide a proposal for Execution Environment Information interacted with broker to support the GRAM's special execution environment.

RADIANCE 프로그램과 인터넷 환경을 이용한 조명시뮬레이션 시스템 개발

송규동,김지현,최안섭 대한건축학회 2003 대한건축학회논문집 Vol.19 No.4

The prediction of illuminances from daylight and artificial lighting has been an important issue in the field of architecture. Architects traditionally have used scale models or various computer programs as tools for predicting the available illuminance in a building and for visualizing the overall lighting quality of the environment. The program requires accurate modeling of the geometric and photometric properties of a designed environment. RADIANCE is a program developed to aid lighting designers and architects by predicting the lighting levels and appearance of a space prior to construction of a building. The modeling of geometric property is usually conducted by commercially available CAD softwares. The modeling of photometric properties includes material color, texture and/or transmittance, daylight availability, and luminous intensity distribution of artificial light sources. The simulation itself uses backward ray-tracing technique to compute radiance values, which are typically arranged to form a photographic quality image. The purpose of this study is to develop a Radiance rendering system that operates automatically on the WWW environment.
