본 논문에서는 생체 신호를 이용하는 체감형 게임 인터페이스 개발을 위하여 근전도 신호로부터 사용자의 동작 의도를 실시간으로 인식할 수 있는 장치를 개발하여 방향성을 필요로 하는 게임에 적용하였다. 근전도 신호를 획득하기 위한 장치는 4 채널로 이루어지며, 정의되는 손목동작으로는 Up, Right, Down, Left로 규정하였다. 각각의 동작으로부터 획득한 신호를 문턱치와 채널 간의 비교를 통하여 사용자의 의도를 인식하게 하였다. 방향성 분류 결과를 통하여 키보드의 방향키를 제어하고, 게임에 적용하게 된다. 개발된 장치는 재미와 흥미를 유도하여 효과적인 운동을 기대할 수 있으며, 상용화된 게임에도 적용할 수 있다. In this paper, we developed the device for an interactive game interface using bio signals which were able to recognize user's motion intention using EMG signals and it was applied to the games which need the information of the muscle motion directions. The module for acquiring EMG signals consists of 4-Ch, wrist-motions were defined as up, right, down and left state. The user's intent was recognized through thresholding and comparing signals of each channel. The classification result of the motion directions could control the arrow keys on the keyboard of PC and it was applied on the various games. This proposed game device can be expected to induce an effective exercise with an interesting and enjoyment, and it can use both self-developed or commercial games.

The objective of this study is to suggest the new mechanism of DHC. At the stage Ⅰ of DHC, DHC velocity increase quickly and that is constant at the stage Ⅱ even if the stress intensity factor(K) increase. Also, the striation spacing on the fractured surface of DHC CT specimen is firstly wide and becomes gradually narrow according to increasing K value. Finally, that becomes constant at the stage Ⅱ. The new DHC model suggested can explain the above situation. To this end, CT specimen is modelled using FEM and the behavior of the elements near the crack tip is examined. Also, the direction of the principal stress, the maximum shear stress and the plastic zone size near the crack tip is calculated.

개정 국어과 교육과정에 나타난 문제점 짚어보기 - 초등과정을 중심으로

김강수(Kim Kang-soo) 우리말교육현장학회 2007 우리말교육현장연구 Vol.1 No.-

  이 글은 개정 국어과 교육과정의 개발과정과 내용체계들을 초등현장 교사의 입장에서 살펴보고 그것이 교육 현장에서 어떻게 구현될 수 있을 것인가, 어떤 문제점을 낳을 수 있을 것인가를 구체적으로 논의해보려는 목적으로 쓴 것이다.<BR>  교육과정은 교육현장의 교사들에게 가르치는 목표와 내용, 방법 등에 관한 지침의 구실을 하지만, 내용과 방법을 포괄적으로 기술할 뿐 아니라 전체적인 체계에서 통일성을 고려하다보니 대단히 추상적인 말로 정리되어 있다. 따라서 현장의 교사는 교육과정 문서만으로는 새로운 교육과정이 구체적으로 어떻게 실현될 것인가에 대해서는 쉽게 가늠하기가 어렵다. 현장의 교사들이 개정 교육과정을 쉽게 이해하고 함께 논의해볼 수 있도록 하려면 현장의 경험을 바탕으로 이야기를 풀어가야 한다고 생각한다.<BR>  이 글은 현장의 경험을 바탕으로 개정 교육과정의 내용 영역을 통합해야 하는 필요성, 지역화 교육이 이루어져야 하는 이유와 구체적 실현 방법, 내용의 적정성과 위계성에 대한 문제를 제기하고 있다. 즉 그것들이 개정 교육과정에서 문제가 되고 있으며, 교육과정의 현실적인 적용을 어렵게 하고 있다는 생각을 담고 있다. 현장의 경험을 바탕으로 논의를 펼쳐나가기 때문에 객관성이나 체계성이 떨어질 수는 있지만, 초등 교육 현장을 실천적으로 반영한 글로 읽히기를 바라며, 현장의 교사들이 개정 교육과정에 대해 적극적으로 이해하고 논의할 수 있는 기회가 되기를 바란다.   The object of this essay is to discuss problems that may arise from revised Korean language curriculum and how the curriculum can be effectively realized in actual teaching environment after due consideration of how the curriculum was developed and put together from an elementary school teacher’s point of view.<BR>  Educational curriculums act as teachers’ guide to help them with teaching contents or teaching methods, but since they include wide range of information and because they were put together considering unity of the information, the contents are very abstract. That is why, teachers cannot easily figure out how the revised curriculum should be practiced with the documents only. In order to discuss how teachers can understand the revised curriculum, I believe it is best to write from actual experience.<BR>  This essay discuss problems in necessity of uniting revised curriculum contents, reason for necessity of localized education system and details of how it is achieved, and propriety of contents. I believe that these are obstacles for practicing revised curriculum and they are holding back actual application of the curriculum. This essay might lack objectivity and systemicity because it is written on the base of one’s experience, but I hope that this essay is read knowing that this essay is reflecting actual practice of education. I also hope that this essay will provide a chance for teachers to understand and discuss revised curriculum education process.

Delayed Hydride Cracking (DHC) tests are conducted by using CT specimens of Zr-2.5Nb at 250℃. The test data is inputed for the FEM model. The stresses of the hydride and Zr-2.5Nb elements near the crack tip of the FEM model are examined. Also, the plastic zone size and average stresses near the crack tip are calculated for checking the effects of the plastic constraint. The material behavior of the elements near a crack tip, the hydride expansion stress, the hydride fracture strength and the size of the plastic zone according to each K are found. Also, Stage Ⅰ and Stage Ⅱ of the unique DHC phenomenon can be explained through an analysis of the plastic constraint force in the plastic zone.

고속도로 투자로 인한 유발교통량 분석에 관한 연구

김강수,Kim, Kang-Soo 한국개발연구원 2006 韓國 開發 硏究 Vol.28 No.2

본 논문에서는 교통시설에 대한 투자로 인한 유발교통량을 분석하였다. 교통시설투자 설명변수인 LK(차로 수 구간거리)와 유발교통량 변수인 VKT(차량 주행거리(vehicle-kilometer)의 관계는 통계적으로 매우 의미 있는 것으로 나타나 고속도로의 서비스 개선은 교통량을 유발시키는 것으로 분석되었다. 지역별로는 경기지역의 변화율이 월등히 높고, 경상남북도, 충청남북도 지역이 그 뒤를 따르는 것으로 나타났으며, 전라남북도의 이동증대효과가 가장 작은 것으로 분석되었다. 본 연구 결과, 교통시설에 대한 투자는 유발교통량을 발생시키나 지금까지는 지방보다는 수도권에서의 유발교통량이 많고 시간이 흐를수록 그 증가폭은 상당 부분 줄어드는 것으로 분석되었다. 유발교통량이 경제성장과 연관이 있다고 가정하는 경우 도로시설에 대한 투자의 지역경제성장효과는 존재하나 점차 줄어들고 있음을 보여주고 있는데, 이는 오히려 지방권보다는 수도권에서 점차 그 현상이 가속화되는 것을 의미하는 것이다. 본 연구는 제한된 교통투자예산하에서 투자효과가 극대화될 수 있는 도로시설 투자방향에 대한 시사점을 제공해 준다. This paper estimates relationships between the supply of national highways, measured in lane-km, and the quantity of traffic, measured in vehicle-km traveled. The analysis uses a panel data set of annual observations for the years 1984 to 2003. By using a log-linear lag effect model designed to capture short and long term effects, the paper estimates that national highway vehicle-km traveled has a lane-km elasticity of 0.268 at the country level (Non-Seoul Metropolitan area) and 0.41 at the Seoul metropolitan area for the short term. For the long term, the paper estimates 0.8 for the country level and 1.23 for the Seoul metropolitan area. This paper finds conclusive evidence that increases in highway lane-miles have generated traffic over the period of study, however the increasing ratio of the generated traffic decreases gradually, particularly during the late 1980s.

In recent years, the dissimilar metal, Alloy 82/182 welds used to connect stainless steel piping and low alloy steel or carbon steel components in nuclear reactor piping system have experienced cracking due to primary water stress corrosion(PWSCC). It is well known that one reason of the cracking is the residual stress by the weld. But, it is difficult to estimate exactly weld residual stress due to many parameters of welding. In this paper, the analysis of 3 FEM models made by ABAQUS Code is performed to estimate exactly the weld residual stress on the dissimilar metal weld. 3 FEM models are Butt model, Repair model and Overlay model and are the plane?strain 2D model. The thermal analysis and the stress analysis are performed on each model and the residual stresses on each model were calculated and compared respectively. Also, the specimen of Butt model was made and the residual stresses were measured by X-Ray method and Hole Drilling Technique. These results were compared with the FEM result of Butt model.

Companies can develop serious regulatory and 1ega1 prob1ems when they have breakdowns in interna1 contro1s. The pain of non-compliance and recent high profile compliance failures have caused companies to budget more money to proactive1y address those types of prob1ems. Compliance programs are a species of internal controls. typically a tai10red set of devices to meet externally- imposed non-financial mandates. A study on the prob1ems and solutions of internal contro1 system and compliance officer is as follows. First. with regard to the scope of interna1 contro1 system and compliance`s ro1e. interna1 control system can be devide financial and non-financia1 controls, to manage risk and compliance can be comprised in non-financia1 control. Second, efficient compliance program can be secured through the compliance officer`s independence and expertise. an objective standard for the ro1e of compliance officer and an audit or audit committee should be showed. Third, compliance must have the position and situation who can cope with externa1 or interna1 pressure. it is necessary to make adopt compliance system by compu1sion. but it is desirable to use the way which the corporation established compliance program can be remitted a fine. This article makes a study on the propriety of introduction of ``internal control system`` and ``compliance officer``. The detailed assertions of the article are as follows. First, in regard of the compliance officer, the officer had better be separated from the legal and audit departments, and the officer needs to be under control by a board instead of an internal auditor. Besides, the compliance officer is recommended to be separated from a person directly in charge of the compliance work. In the case, the paper suggests that there be no qualification on the compliance officer, but the person in charge of the compliance affairs be a lawyer including a foreign lawyer. Second, with regard to the scope of the system and a legal basis, the scope of the internal control system for a listed company needs to be limited to the compliance of laws and regulations excluding risk management operation. Also, the internal control system had better be obligated not by a statute but by a more flexible rule of Korea Exchange. Third, the study shows how much important the incentives are for more adoption of the compliance system by listed companies by introducing good examples of other countries.
