In this paper, we developed a low cost smart puck system that can interact with the intuitive operation of natural finger touches. The tangible smart puck, designed for capacitive tabletop display, has Arduino embedded processor which communicates only with the MT server. The MT server communicates both to the smart puck and the display server. The display server displays the relevance information on the location of the smart pucks on the tabletop display and handles interactions with the users. The experiment results show that the accuracy of identifying the smart puck ID was very reliable enough to use in practice, and the information presentation processing time is confirmed excellent enough compared to traditional expensive commercial products.

멀티미디어라는 단어는 이제 더 이상 낯선 용어가 아니며 일반에 널리 알려지고있다. 사람에 따라 그에 대한 개념이 약간씩 다르긴 하지만 그 차이는 미미하다. 이는 산업계에서도 마찬가지이다. 멀티미디어가 산업을 변화시키고 있다는 사실은 누구나 인정하고 있으며, 단지 업체별로 멀티미디어에 대한 대응 전략이 각 업체의 특성에 따라 차이를 보이고 있을 뿐이다. 다양한 정보처리를 지원하는 멀티미디어 OS는 현재 두가지 방향으로 발전하고 있는데, 그중 하나가 가정용 시장이다. 본 고는 일본의 니케이 일렉트로닉스지가 보도한 내용을 중심으로 멀티미디어 OS를 요약, 소개한 것으로, 가정 전기제품의 정보처리용으로 신영역을 개척하고 있는 멀티미디어 운영체계(OS)에 대해서 기술하고자 한다. 현재 가정용 멀티미디어 OS는 카레이다(Kaleida)사가 개발하고 있는 재생전용 멀티미디어 플레이 OS이고, 다른하나는 PC를 시장으로한 애플사의 퀵타임(Quick Time), 마이크로소프트사의 MME (MultiMedia Extension)와 IBM사의 MMPM/2 (MultiMedia Presentation Manager/2)가 그 주도권을 다투고 있다.

대용량의 네트워크 인프라가 확대되고, 네트워크를 통한 DV, HD 급의 고화질 비디오 전송이 보편화 되면서, 고화질의 비디오에 몰입감, 현실감을 증진시키기 위한 스테레오 HD 비디오 전송이 가능하게 되었다. 본 논문은 IP 네트워크를 통해서 스테레오 HD 비디오 전송을 가능하게 해주는 소프트웨어 기반의 HD 비디오 전송 시스템에서 효과적으로 몰입감과 입체감을 제공하기 위해 충족되어야 하는 좌우 영상의 동기화에 필요한 요소들을 다룬다. 제안된 동기화 기법은 수신 측에서 최종적으로 동기화된 좌우 영상을 통해 스테레오 HD 비디오를 얻기 위해서 좌우 카메라로부터 영상의 획득 시, 획득된 영상의 네트워크 전송 시, 또 수신된 영상의 재생 시 좌우 영상의 동기화한다. 결과적으로 동기화 된 좌우 영상을 통하여 몰입감과 현실감을 가지는 스트레오 HD 비디오를 실시간으로 감상할 수 있다.

In this study attempts were made to identify the areas of single animal ploughing (SAP) in Bangladesh, causes of its localization and the socio-economic constraints hindering the expansion of the system. To determine the areas of single animal ploughing, 123 upazilas of 15 districts were surveyed. Of them, 16 upazilas were found heavily engaged with this system. A detailed investigation of 469 SAP and 439 double animal ploughing (DAP) farmers revealed that there was significant difference between the two systems in respect of cost of production and yield per unit of land. The benefit/cost (B/C) ratio was higher in SAP system. However, no significant difference was observed in respect of time required for ploughing, intensity of cropping, cost of implements, and cost of repairing implements (except yoke). The study recommends for expansion of SAP system in areas where buffaloes are concentrated. Fro this purpose, logistic and institutional supports need to be made available.

This is a paper intended for initial stage of vehicle modeling and design. The needs to determine a variety of vehicle suspension parameters required for initial design has been difficult and time-consuming task. In order to facilitate a concise and efficient presentation of initial vehicle design procedure, this paper uses a mathematical model and physical geometry. Vehicle model consists of dimensions, inertias and mechanical constants. These vehicle model parameters divided into several categories : basic parameters, coefficients and constants, design specification, spring and damper, bush stiffness, stabilizer bar, suspension geometry, tire, and vehicle weights of various design condition. This paper uses a vehicle design fundamental (VDF) program running under Windows 95 graphical interface. The features of VDF will be briefly outlined in this paper.

This keynote presentation covers the subject of intelligent systems development for monitoring and control in various NASA space applications. Similar intelligent systems technology also has applications in terrestrial commercial applications. Discussion will be given of the general approach of intelligent systems and description given of intelligent systems under prototype development for possible use in Space Shuttle Upgrade, in the Experimental Crew Return. Vehicle, and in free-flying space robotic cameras to provide autonomy to these spacecraft with flexible human intervention, if desired or needed. Development of intelligent system monitoring and control for regenerative life support subsystems such as NASA's human rated Bio-PLEX test facility is also described. A video showing two recent world's firsts in real-time vision-guided robotic arm and hand grasping of tumbling and translating complex shaped objects in micro-gravity will also be shown.

A recent development in the Flat Panel Display(FPD) industry requires an auto-alignment system which is operated in high speed and high precision. In the FPD production process, aligning photo-mask with respect to guide mark printed in the glass should be accomplished in the accuracy of sub-micron order. So the system has high bandwidth and needs a dedicated control system which is fast and robust enough to control linear motors in precise manner. Proposed auto-alignment system structure in this presentation which consists of the master controller board, the DSP position controller board which controls 3 axis precision linear motors, the servo system and the man machine interface software. Designed and tuned under repeated experiments, the proposed system showed a reasonable performance in the aspect of rise time and steady state error.

Physical tests are performed at various stages of the development cycle of a product, from prototype validation to product qualification. Although costly, there are growing demands for qualification tests like endurance vibration testing to be more representative of the real world. At the same time there are growing demands to assess the durability of these items based on FEA simulation. In this paper, we will explain how to set up a CAE-based test and how to correlate the results with some physical measurements. Specific assumptions will be explained and some advantages of using virtual tests will be highlighted such as the reduction of the number of prototypes needed, investigations on failures, evaluation of the level of reliability via sensitivity analysis, evaluation of the margins are at the end of a successful test. This presentation will therefore focus on explaining and showing how virtual tests can enrich the exploitation of physical tests.

Acetaminophen (AAP) overdose can result in potentially serious hepatotoxicity. The ingested dose and time from ingestion to presentation are important prognostic factors. Toxic dose in adult is thought to be at least 10 g or 200 mg/kg. However, early management of acute overdose should be guided by the plasma AAP concentration. The antidote for AAP poisoning is N-acetylcysteine (NAC). It provides complete protection against hepatotoxicity if given within 8 h of acute overdose. If the concentration is above the possible toxicity line as predicted by the Rumack-Matthew nomogram, either the 72-hr oral or the 20-hr intravenous NAC regimen should be administered. NAC is also effective if started late in patients with established hepatic failure. This article summarizes the current consensus of clinical assessment and management for acute AAP overdose.

Until now, architects have used traditional methods in order to develop architectural forms and use a digital technology as presentation tools. The field of digital technology has been expanded to control easily architectural data, eventually leads to the creation for creative ideas, which were belong to mainly designer's talent. It has been educated by using digital tool in foreign universities but in our case a little university try to do. So we need an adequate curriculum and educational media because of digitalized data, originated architectural form and reduction of time and money. In this paper, as it is surveyed the present situation of architetural education by using digital tool in domestic and foreign country, it can be used as the fundamental data that architectural education by using digital tool is initiated In our universities.
