뇌-컴퓨터 인터페이스로 활용하기 위한 시도로서, 인간의 가장 간단한 의사 표시인 긍/부정 의사와 관련한 뇌파를 측정하고 시간-주파수 분석(단시간 푸리에 변환)을 수행하였다. 반응 동작과 관련한 $\mu$파와 $\beta$파, 그리고 인지 정보 처리와 관련한 ${\gamma}$파의 시간에 따른 변화를 살펴보고 선행 결과들과 비교, 토론하였다.

손끝으로 물건을 문지르거나 잡아 질감을 느끼는 경우 나타나는 현상을 Hertzian 접촉이론을 응용하여 수학적인 모델링을 하였다. 물체표면에 손끝이 접촉하여 눌러지게되면 변형이 일어나게 되고 변형된 모양과 정도에 따라 촉감을 느끼게 된다. 손끝은 비선형으로 변형되므로 누르는 변위에 따라 탄성계수 값이 변하는 현상을 실험을 통하여 확인하였으며 모델링한 식과 비교한 결과 유사한 경향을 보였다. 특히 손끝이 직물을 누르며 문지를 때 힘이 크기변화를 측정하여 질감표현과의 관계를 분석하였다.

본 연구에서는 14명의 남녀 대학생을 대상으로 열환경 챔버 내에서 여름철 열적 반응을 조사하였다. 여름철 온습도 범위에 해당하는 4가지 온도와 3가지 상대습도의 조합에 의한 8가지 조건에서 실험을 수행하였고, 주위 열환경에 대한 피험자의 심리적 반응을 살펴보기 위하여 전신온냉감과 쾌적감을 조사하였다. 조사결과를 국내 환경 실험실 연구 및 현장조사 결과와 비교하였고, 환경 실험실 연구 수행시의 문제점을 검토하였다.

Human feels kinesthetic sense in response to the force acted on him. In order to represent kinesthetic sense, a force is analyzed as mechanical impedance (i.e., stiffness or damping) and implemented by active impedance control. In this research, a 3-dimensional arm motion generator is developed to present various mechanical impedance characteristics to an operator. An introduction of virtual reality provides not only a visual effect in virtual environment but also the change in force synchronized with the visual effect in real time.

This research aimed 1) to analyze the relationship between consumer's emotional needs and elements of textile design in the 1st survey 2) to investigate textile design process presently conducted in the industry in the 2nd survey, and 3) to suggest a desirable direction to improve the textile design process based on a comparison of the results obtained from the two surveys. A description system and an emotion model on textile design were redeveloped as research devices in this study. In the 1st survey, total 600 respondents were sampled and asked to report their emotional response on 50 representative types of textile design, on a emotion measurement scale. The data set obtained from the 1st survey were statistically analyzed. In the 2nd survey, a depth interview was applied to qualitatively analyze the textile design process presently conducted in the industry. The results from the two surveys were compared.

A driver's emotion is a very important factor of safe driving. This paper classified a driver's emotion into 3 major emotions, can be occur when driving a car: Surprise, Joy, Tired. And It evaluated the classifier using Hidden Markov Models, which have observation sequence as bio-signals. It used the 2-D emotional plane to classfiy a human's general emotion state. The 2-D emotional plane has 2 axes of pleasure-displeasure and arsual-relaxztion. The used bio-signals are Galvanic Skin Response(GSR) and Heart Rate Variability(HRV), which are easy to acquire and reliable. We classified several moving pictures into 3 major emotions to evaluate our HMM system. As a result of driving simulations for each emotional situations, we can get recognition rates of 67% for surprise, 58% for joy and 52% for tired.

The main purpose of this study was to investigate preschoolers understanding whether thinking influences emotion with cognitive cueing. The subjects were 75 preschoolers of the J, Y, & K kindergartens located in Taegu. They were 4-(12 boys and 13 girls), 5-(12 boy and 13 girls), and 6-years(13 boys and 12 girls) old. The instruments were 4 stories and 11 pictures per a story used in Lagattuta, Wellman & Flavell(1997). The responses given from preschoolers were classified in terms of cognitive cueing response. The major results showed that an initial understanding of cognitive cueing in some preschoolers revealed the evidence of significantly developmental changes during the preschool years. Cognitive cueing responses were significantly different according to thinking prompt which is the question to help preschoolers explanations. This result suggested that the instruments of measurement for preschoolers should be improved as possible as they can understand.

본 연구에서는 안정 상태에서 일반 공기 중에 산소 농도(21％) 환경에 비해 외부에서 고 농도(35％)의 산소 공급이 혈중 산소 포화도(SPO2), 심박동율(Heart rate), 피부전도도(Galvanic skin response)에 어떠한 영향을 미치는지를 검증하고자 한다. 35％의 고농도 산소를 2L/min의 양으로 일정하게 공급할 수 있는 산소 공급 장치를 이용하였고, 뇌 질병이 없는 5명의 대학생들이 피험자로 참여하였다. 21％의 비해 35％ 산소 농도에서 모든 실험 참여자의 3분 동안의 평균 심박동율은 감소하였고 평균 혈중 산소 포화도는 증가하였다. 그러나 피부전도도는 차이가 없었다.

To do this study, we produced cooling vest newly. Rectal temperature was ascended approximately from 37.2$^{\circ}C$ to 38.05$^{\circ}C$ in lab, but wearing cooling vest, the temperature was descended 0.2 while wearing developed product compare with existing product. Mean skin temperature which was showed distribution from 32.8∼36.5$^{\circ}C$, it was descended 1.0∼1.1$^{\circ}C$, while wearing cooling vest and comparing with existing product, wearing developed product was lower 0.5$^{\circ}C$, While wearing developed product, it was found that they had lower tendency than exiting product. Specifically in case of temperature within clothing(chest) 0.2∼2.0$^{\circ}C$ in case of humidity within clothing 2∼8% RH. Facts from above we confirmed that clothing microclimate had been improved and space was happened between body and garment in order to control. In subjective sensation, existing product made negative response during experiment period from participants, but developed product was nearing to comfortable area.
