Status of high intensity LED, one of the recent issue in industry is reviewed. In a system view, various power supply methods for multiple array construction are introduced rather than one for single LED. Custom IC for driving LED and different circuit for applications are also considered.

In this paper, design and development experiences of a vision based robotic assembly system for electronic components are described. Specifically, the overall system consists of the following three subsystems each of which employs a 16 bit Preprocessor MC 68000 : supervisory controller, real-time vision system, and servo system. The three microprocessors are interconnected using the time shared common memory bus structure with hardwired bus arbitration scheme and operated as a master-slave type in which each slave is functionally fixed in view of software. With this system architecture, the followings are developed and implemented in this research; (i) the system programming language, called 'CLRC', for man-machine interface including the robot motion and vision primitives, (ii) real-time vision system using hardwired chain coder, (iii) the high-precision servo techniques for high speed de motors and high speed stepping motors. The proposed control system were implemented and tested in real-time successfully.

The FDAS(Flight Data Analysis & Animation System) is a comprehensive analysis system designed for the improvement of flight safety. FDAS provides decoding, analysis and animation tools that can be used for investigation of data origination primarily from Flight Data Recoders(FDRs), Quick Access Recoders(QARs), Using FOQA(Flight Operation Quality Assurance) Data Analysis, an analyst can perform a variety of functions including data smoothing, interpolation, differentiation, integration, calculator function, flight path generation, performance routines, as well as user-programmed functions. Utilizing data captured and processed by our FDAS software module, FDAS provides high-fidelity 3-D aircraft views and instruments views. Multiple windows enable you to view the situation from a variety of perspectives, including out-of-window, chase plane ...

In Japan, there are over the 100's fires in the social welfare organs every years. People are interested in fire protection who live in an institution for the aged or weak person's places and worried about it. I surveyed the social welfare organs were safety from fire to firewarden who worked at an institution for the aged in Tokyo. In the paper, I asked how do you think about the fire safety problems and condition of the facilities. And base on firewarden's view, I reviewed(examined) the fire prevention measures, each facility's problems and how to improve the fire protection.

Through a year's commercial operation, Korea High Speed Railway has solved defectives from several breakages at the beginning and is going into the stage of stable operation. Among issues, wheel wear becomes a matter of primary concerns in view of vehicle's stability and maintenance. It was understood as above that wear status has been improved in the test by which railway system including vehicles and tracks was stabilized during a year's commercial operation, comparing to that with excessive wear in the trial operation prior to opening to the public. To make out wheel's wear status and characteristics of equivalent conicity at present when the service has been introduced a year ago and the average cumulative mileage of vehicles reach almost 500,000km, wheel's wear types were analyzed with the current vehicles in service.

From the study on the relation of O-mi(五味) and Sam-Eum-Sam-Yang(三陰三陽), the conclusion is as follows. The system of Sam-Eum-Sam-Yang(三陰三陽) in human body expresses a kind of inner images[象] of continuous life, that implies many complex view-points, in both inside and out-side according to time flow. Besides, O-mi(五味) is one of very important native properties of all existences, that is accepted from the state they have been located in, and it includes the principles of real nature. Based on understanding of Sam-Eum-Sam-Yang(三陰三陽), when we investigate properties of O-mi(五味) for practical use, the concepts of contraction and extension[收散], softening and hardening[軟堅], and slowing and fastening[緩急], referred in Naegyeong(內經), directly express the images of Sam-Eum-Sam-Yang(三陰三陽).

Crop Protection Products (CPPs) are a useful weapon in our fight against the pests, diseases and weeds that harm or destroy our food. To be effective CPPs need to exhibit some persistence. The consequence of this is that residues of the original material or its metabolites may remain on food and thus there is a potential for the intake of such residues. The issue of CPP residues in food is an emotional subject and is rarely debated rationally or supported by scientific facts. Media headlines like “Poison in our food” or “These days enough Pesticides (CPPs) are sprayed onto vegetables to turn you into one” are testimony to the high level of emotion that surrounds the subject of CPP residues in food. Recent surveys of consumers have indicated that more than 80 percent view CPP residues in food as a “serious hazard”. This significantly exceeds concerns over drugs, hormones in meat, nitrates in food, irradiated foods, food additives, or artificial colours.

"Sustainability" and buzzword as in many areas of products produced and studies in progress, in situations of domestic "green fashion" of the Progress and identify problems and advanced in value sustained growth that can be done fashion design, the future of the gauge view there is need. For the purpose of environmental protection and resource conservation of the eco-fashion trend, "recycling" of the low-growth, emphasizing the ethical responsibility to pursue by the aesthetics may be limited in terms of avoided. Environment, most notably an "issue" fashion emerged as a growing, destroying a temporary fashion trend as a "recycling" of the limitations and pro-technology and design of the added value of recombinant and advanced recycling design trends, attracting attention "upcycle" Case of the aesthetic value and spiritual value of the designer by giving understanding and a new aesthetic values to the area you want to raise the possibility of extension.

방대한 양의 데이터를 처리하는 요구가 증가하면서 그로부터 유용한 정보를 추출해낼 수 있는 방법에 대한 필요성이 증가하고 있다. 메타데이터(metadata)를 관리하는 파일 시스템은 이러한 일을 빠르고 효과적으로 수행할 수 있는 방법 중 하나이다. 본 논문에서는 통합적인 메타데이터 관리를 가능하게 하고, 임베디드(embedded) 환경으로도 확장이 가능한 새로운 파일 시스템을 제안한다. 이를 위해 기존 리눅스(Linux) 파일 시스템을 바탕으로 새로운 파일 시스템을 설계하고 제시한다. 이렇게 설계된 파일 시스템은 사용자와 응용 프로그램에게 데이터의 다양한 뷰(view)를 제공할 수 있고 시스템 상에 존재하는 많은 양의 데이터를 통합하여 효율적으로 관리 할 수 있다.

Debris flows are a natural hazard which looks like a combination of flood, land and rock slide. Large rainfall in July 2006 produced several large scale debris flows and many small debris flows that resulted in loss of life and considerable property and highway damage, as was widely reported in the national media. The hazard "debris flow" is still insufficiently researched Furthermore debris flows are very hard to predict. In this paper, a general over view of the debris flow problems along the highway, a generic way for the design and dimensioning of flexible barrier systems will be presented. A brief description of the various unique barrier types will be provided, too. The future for these barrier concepts looks promising because these barriers represent the state of art for such applications and are superior to many other available options.
