일반적으로 원자력 관련 연구개발은 타 산업 및 사회에 미치는 파급효과가 크고, 참여 연구원 및 대중 안전에 대한 위험도가 높으며, 대규모의 투자비용이 요구되는 특성을 지니고 있다. 이러한 이유로 원자력 산업은 일찍이 품질보증 개념을 도입하여 원자력 시설의 안전한 이용을 도모하여 왔다. 최근에는 원자력 연구개발 분야에서도 연구결과의 신뢰도 확보 및 안전한 연구수행을 보장하기 위하여 품질보증 적용의 필요성이 강조되고 있다.(중략)

A signal equipment improvement project for the existing facility ATS to ATP is under construction in Kyung-Bu and Ho-Nam commercial line including 400 rolling stocks. But there was a concern for the interface between KTX OBCS and ATP from the beginning of the project. At present, this is the front burner event. This paper introduces interface checking and predicted failure point between KTX OBCS and ATP improvement system. Through this measure the optimal installation of the ATP will be possible. The study was made under maintenance efficiency including reliability because the KTX signal equipment must qualify the above condition.

The importance of usability evaluation is increasing in developing the system(or product). Many usability measures and test methods have been developed in the fields of ergonomics and cognitive engineering. A systematic usability effort using established methods may be qualify as usability engineering. In this paper, general aspects of the usability engineering are introduced, and application methods of usability engineering model based on product's life cycle are presented.

Facial expression is innate communication skill of human. Human can recognize theri psychological state by facial parameters which contain surface movement, color, humidity and etc. This study is to quantify or qualify human emotion by measurement of facial electromyography (EMG) and facial movement. The measurement is taken at the facial area of frontalis and zygomaticus The results is indicative to discriminate the positive and negative respond of emotion and to extract the parameter sensitive to positive and negative facial-expression. The facial movement according to EMG shows the possibility of non-invasive technique of human emotion.
