Objective : To report the effects of a specific intervention, the Interactive Metronome$^{(R)}$ (IM), on timing, attention and motor function of a children with ADHD. Methods : The study is case reports about two boys with ADHD. One boy who is born 2008 is attending general elementary school as a first year student (case 1), and another boy who is born 2001 is attending general elementary school as a second year student (case 2). For each case subject, IM training was provided during 3 weeks, from January 2015 to Febrary 2015. Evaluations were performed pre- and post-intervention in order to exam timing, attention and motor skills. The measurements uses in this study are Long Form Assessment (LFA) for the timing, RehaCom screening module for the attention, and Bruininks-Oseretsky Test of Morot Proficiency, second version (BOT-2) for the motor function. Results : The timing function was improved in both cases since both showed reduced response time for all motor tasks of LFA. In terms of attention, case 1 showed improvement of visual attention division, neglect and response Inhibition, and case 2 showed improvement of sustained attention. Lastly, in the BOT-2, case 1 showed improved the percentile rank of short (from 42%ile to 96%ile), and case 2 also showed similar improvement (from 21%ile to 66%ile). Conclusion : This study provides positive evidence that the Interactive Metronome$^{(R)}$ training has positive power to facilitate several body functions such as timing, attention and motor control of children with ADHD, through two case studies.

The multimedia services like video-conferencing and interactive multimedia services require the support for the multipoint-to multipoint connections from the networks. The routing and signaling protocols for supporting these connections in ATM networks have been a interesting topics in the Telecommunication standardization sector such as ATM-Forum. In this paper, we survey and discuss the various well-known switching algorithms for multi-way communication.

본 연구에서는 실영상의 재생 속도를 가변적으로 제어하여 인터렉티브한 환경을 제공할 수 있는 소프트웨어를 개발하고자 하였다. 시청각 정보로 이루어진 동영상에서 시각 정보에 관한 정보만을 추출하는 필터부, Decoder Filter로부터 Upstream된 Stream의 Time Stamp를 변경시키는 변환 필터의 제작 및 Microsoft DirectShow Component를 이용한 영상의 가변적 속도 제어 프로그램으로 이루어진다. 본 소프트웨어의 사용 결과 실영상을 최소 1/8배속에서 최대 5배속사이의 배속을 임의로 제어할 수 있었으며, 영상이 끊기는 현상 없이 부드럽게 재생 되었다.

최근 분산발전시스템에서 계통에 전압이상이 발생하더라도 일정시간 계통과 연결해야 하는 FRT 기능이 요구되고 있다. 그러나 인버터에 독립부하가 존재하는 경우, 계통의 이상전압 이 독립부하에 그대로 걸리게 되는 문제가 있다. 본 논문에서는 계통이상시에도 FRT 기능을 준수함과 동시에 독립부하에도 일정한 품질의 전압을 공급할 수 있는 전압보상 기법을 제안한다.

The most important factors for a product to survive in the market are cost and quality. In recent years, quality proceeds to cost. There are many techniques of use to improve the quality of a product. One of the techniques is applying statistical methods (especially Taguchi method) to real operational conditions for a continuous manufacturing process in P company. There are 91 factors to control in the process. So, we predetermined 7 main effect factors and 6 interactive effect factors by statistical methods and advices of engineers. With these 13 factors, we determined the optimal level of operations for the process.

In this paper, we present a robot off-Line programming system with collision detection. The collision detection is a very important factor of robot oft-line programming system for collision avoidance, path planning, and so on. The System developed in this paper, basically using an algorithm for the minimum distance calculation between general polyhedra. The proposed system shows an exact and interactive result in static and dynamic environments.

In this paper, NCTOP is an interactive NC auto programming system for two-dimensional machining. NCTOP consists of seven modules, that is pattern form input, free form input, AutoCAD interface, logic processing, postprocessor processing, output, and database upgrade module. The geometry information of a workpiece to be machined is put into NCTOP program. Then it generates NC program which is final output. NCTOP uses the machining dates from the data base.

This paper introduces the program to develop graphics-oriented, interactive, computer-aided design modules for machine elements which are developing in Mechanical Engineering Department of The Ohio State University in U.S.A. The CAD modules are developed to be efficiently performed within the arena of minicomputer- and personal computer-based computer-aided design. In addition, this paepr deals with the state-of-the-art in computer-aided design.

In design of the plastic injection mold, most of drawings are composed of basic entities. It is very easy to produce many kinds of drawings by Group Technology. Group Technology is a technique In which part similarities are used to classify parts into part families according to either geometric shape and size or processing requirements. Almost data for the mold are decided during the assembly design. A system which shows a good interfaces between the design stage and producing part exploding Is developed using AutoCAD system and data conversion technique.

A digital preview controller is designed for tandem cold mills to achieve a better improvement of the thickness accuracy. And simultaneously a blocked noniteracting controller is synthesized for rejecting the interactive effects among adjacent stands and for controlling independently each roll stand of landem cold mills. The performance effects and characteristics of the suggested roll control system are discussed in the practical view points. The simulation results show that the thickness accuracy of tandem cold mills can be largely improved by the blocked noninteracting and digital preview contoller.
