Although the recognition and emotion about space is subjective and individual, if standard is proposed through common factor, objective, quantified space image evaluation will be available. In addition, space image evaluation standard caused by recognitive-emotional factor can meet requests of space users and increase psychological satisfactions. The purpose of this study is to grasp the space image caused by recognitive-emotional factor in space with PAD model and analyze the evaluation of space image giving visual, recognitive and emotional effects. The analysis result revealed that 'joyfulness' and access-avoidance had a very similar distribution. The result means that space is evaluated with the degree of 'joyfulness' for space and it is led by approach-avoidance behavior. The recognition factor that forms and evaluates space image and decides approach-avoidance is expressed as adjective images such as 'fresh, joyful, light and static and its emotional factors are adjective images such as 'calm, allowable, joyful and quiet'.

Nasucon lamp and Russian ones, which are coated with some special materials on the glass bulb, gave good clinical results for a cancer therapy. They are experimentally studied with Automatic Bioelectric Response Recorder on the six placements of the electrodes (two feet, two hands and two foreheads). They reduced the current rather than the control (natural) state. However infrared lamp and Chinese God light did not reduced the value current. Hemoglobin in blood. Brown gas, Ti$_3$SiC$_2$ and Nasucon have planar crystallizing $\pi$-bonding bonding layer and covalent bonding one in sequence commonly and thus the alternating magnetic fields are protected. Nasucon lamp and Russian ones utilized electric bulbs in order to generate alternating magnetic fields and to produce absorbing force.

This study aims to validate the effectiveness of VE system with an arm-master in the evaluation of virtual prototype. A virtual kitchen with a refrigerator was presented in a CAVE system. Subjects put in and pull out virtual objects by using the arm-master. Twelve subjects participated in six experimental conditions: three types of refrigerator door grips and two reaction forces. After each trial, subjects evaluated a virtual refrigerator in terms of easiness of operation, similarity in force, presence etc. The results show the subjects preferred vertical grip than horizontal grip and light reaction force than heavy one. The VE system with the arm-master will be very helpful in the design evaluation of virtual prototypes.

지구 온난화 현상에 따른 기온 상승과 환경오염으로 인하여 생태계의 예상치 못한 변화는 여름철은 물로 겨울철에도 모기의 발생과 전염병이 증가하고 있다. 이러한 문제를 해결하기 위해 다양한 해충박멸을 위한 제품들이 출시되고 있는데 환경 파괴 등 여러 문제점들이 대두되고 있어 환경오염을 방지하기 위한 해충 퇴치를 할 수 있는 제품개발이 필요하다. 본 연구는 환풍기를 이용해 해충의 습성(색 구분, 후각, 청각, 촉각)을 파악한 후 해충이 좋아하는 빛으로 유인하여 해충을 환기와 동시에 밖으로 배출해내는 환경 친화적인 제품에 관한 연구이다. 이론적 고찰을 통하여 해충이 좋아하는 요소를 파악한 수 가장 효과적으로 해충을 퇴치할 수 있는 환풍기의 구조, 풍량, 빛의 밝기 등의 유인요소를 실험을 통해 검증하여 이 결과를 이용하여 실제 디자인을 실행한다.

본 연구는 색 조명 시각 자극이 정상인의 기억작용에 어떠한 영향을 미치는가를 평가해보고자 하였다. 피험자는 대학생 성인 남, 여 20대 (20-30세) 각각 10명을 대상으로 실시하였으며 자체 제작한 기억 테스트(Memory test)를 활용하였다. 색채 환경은 방음 암실에서 백색광원을 파장대별로 필터링한 색 조명을 사용하여 제시하였으며 실험 측정 파라미터로서는 정확도(accuracy), 반응시간(Response time) 그리고 학습시 주로 활성화 되는 뇌파인 알파와 세타파의 주파수 대역을 측정하여 기억기능을 수행하는 대뇌의 기억 활성화 상태를 색 조명에 따라 비교 분석 하였다. 측정결과 각각의 색조명에 대한 정확도는 파랑색에서 증가하고 반응시간을 노랑과 파랑에서 감소했다. 뇌파의 활성화에서도 흥분이나 긴장을 상징하는 빨강의 색보다는 파랑색과 보라색과 같은 단파장의 색이 알파파나 세타파를 활성화 시키는데 영향을 줌을 알 수 있었으며 이러한 연구가 감성적 색 조명 디자인의 응용이나 색 관련 제품 계발에 적극 활용될 수 있을 것이라 기대된다.

This study investigated the effects of certain specific wavelengths of lighting on the autonomic nervous system (ANS) using the heart rate variability (HRV) as an index. Six subjects with normal color vision participated n this study between 15:00 and 17:00 hr to neutralize any visual differences arising from circadian rhythm. The environmental conditions of the laboratory were maintained in complete darkness and the temperature was equilibrated at 24$\Box$ with a relative humidity of 60%. Subjects were only subjected to light stimulation when the pupil of dyes attained a minimum size of 2 mm by projecting illumination equalized with the same spectral radiance of 500-700 nm with 50-nm internal radiance. HRV was calculated from electrocardiogram (ECG) with systematic respiratory control at 0.35 Hz. The results suggest that illumination with certain wavelengths may induce ANS activation.

The imploded open $\pi$-rays comprise of the space and their diameters are distributed from nearly zero to infinite. The change of the potential energy in the open $\pi$-ray produces an attraction force between them and it is sensible to the geometric shape factor and its frequency. The equivalent principle of general relativity means that in the wave equation its velocity of the force wave is infinite. The change of the state in a open $\pi$-ray(or any force wave) can be transferred to any sensible open $\pi$-ray via space at a finite velocity. Many properties of the light wave can be deduce from the motions of open $\pi$-rays.The nonsteady and steady Schr dinger equations include the dynamics of open $\pi$-rays and closed $\pi$-rays.$\prod$-ray is a tool of entity for constructing physics and metaphysics at the same time.

This study was aimed to determine color sensibility factors for naturally dyed fabrics and to investigate their relationship with color variables such as hue and tone and dyes. Two hundreds different fabric colors prepared by a variety of natural dyeing were subjectively evaluated by color experts, which resulted in three color sensibility factors including 'Pleasant', 'Comfort', and 'Modem'. Among hues, Yellowish shade by natural dyeing was found as more pleasant and more comfort than any others. Among main tones for natural dyeing, g(grayish) and ltg(light grayish) were more felt in 'Comfort' whereas d(dull) more in 'Pleasant'. As for dyes, Gardenia Blue, Gardenia Yellow, and Anato tended to give feelings of 'Pleasant' whereas Raw Indigo and Loess did 'Comfort'.

The aim of this study is to protect workers and pedestrians from accidents at night or bad weather by attaching optical fiber to existing safety clothing that is made only with fluorescent fabrics and retroreflective materials. A safety vest was designed and manufactured by applying optical fiber, and energy-harvesting technology was developed. The safety vest was designed to emit light using the automatic flashing of optical fibers attached to the film, and an energy harvester was manufactured and attached to drive the light emission of the optical fiber more continuously. As a result, first, the vest wearer' body was recognized from a distance through the optical fiber and retroreflection, which helped prevent accidents. Thus, this concept helps in saving lives by preventing accidents during night-time work on the roadside or activities of rescue crew and sports activities, or by quickly finding the point of an accident with a signal that changes the optical fiber light emission. Second, to use the wasted energy, a piezoelectric-element power generation system was developed and the piezoelectric-harvesting device was mounted. Potentially, energy was efficiently produced by activating the effective charging amount of the battery part and charging it auxiliary. In the existing safety vest, detecting the person wearing the vest is almost impossible in the absence of ambient light. However, in this study, the wearer could be found within 100 m by the light emission from the safety vest even with no ambient light. Therefore, in this study, we will help in preventing and reducing accidents by developing smart safety clothing using optical fiber and energy harvester attached to save lives.
