The methods used in this study included investigation of media facades used for landmarks in downtown areas in previous studies, visits to these areas, and recording of media facades. The changes in the colors or the size of buildings were analyzed among the recorded cases and 12 of these cases were selected for further study. The sensibility preference of the media facades was evaluated by sorting the 12 kinds of media facades, and providing them as materials to a group of 60 participants (40 undergraduate and 20 graduate students majoring in architecture and design) consisting of an equal proportion of males and females. This study addressed the following four_stage questions: 1) Five questions of recognition evaluation about media facades and the cognitive evaluation items of emotional vocabulary and color preference in each research case; 2) sensibility preference items regarding the media facade color design; and 3) design evaluation items of the media facades; 4) Video clips and still images were recorded from a middle distance at 7p.m to 11p.m. in central New York, Singapore, Seoul, and Beijing. The participants looked at the changes in colors through the video clips in each case and evaluated their preferences through 23 pairs of emotional vocabulary items using system dynamics. Construction of an emotional vocabulary followed, based on previous studies about media facades and color design. To evaluate the sensibility preference and the perceived representative colors of the media facade, this study suggests new emotional responses that depended on the color emotional vocabulary of light in the LED lighting technical evaluation methodology. A media facade with a moving change of colors, unlike a fixed landscape color design, suggests a new communication method based on architectural factors. New architectural color coordination can be presented for urban landscapes at night. Designs that factor in the pedestrians' emotional vocabulary or preference should take precedence over the use of high luminance and various colors.

With the ingenious properties of unconstrained formativeness and frank expression of materiality the exposed concrete became popular with numerous architectures. The application of the exposed concrete has expanded to indoor environments such as commercial and residential spaces beyond the building exteriors with the uncompromising nature of its materiality. The purpose of this study is to conduct sensibility evaluation of the exposed concrete finish in interior spaces. The sensibility evaluation is conducted through a survey on a set of space models of the exposed concrete finish. The three rendered space models were evaluated by emotional vocabulary of 18 pairs of words. The result were as follows: First, the emotions derived from the exposed concrete finish are 'modern', 'cold', 'simple', 'restrained', 'rough', 'dark', 'new', 'chic', 'familiar' and 'eco-friendly'. Second, three sets of space models with alternative materials on walls and floors in exposed concrete interior space showed clear difference in sensibility. A space with the exposed concrete finish on the floor, the walls and the ceiling showed the results of 'cold', 'dark', 'rational' and 'masculine'. In the exposed concrete finish environment with wood flooring 'comfortable', 'warm', 'bright' senses and with white paint finish on the wall 'bright', 'practical', 'ordinary' and 'restrained' senses were obtained. Third, all three images achieved senses of 'chic', 'modern', 'new', 'pleasant', 'environment friendly' and 'satisfactory'. The modernity and stylish expressions of the exposed concrete finish were kept with the application of different material finishes as well as complementing its cold and rough expressions with warmth and brightness.

본 논문에서는 전두엽과 두정엽의 4채널 뇌파를 이용하여 인간의 쾌적성 평가를 위한 알고리즘을 개발하고자 한다. 알고리즘은 선형 예측 분석과 신경회로망으로 구성되며, 많은 피검자들의 템플릿(template)을 활용한다. 먼저 다양한 실험 환경을 조성하여 쾌적 및 불쾌적한 상태의 뇌파를 수집하였다. 그리고 나서 개발된 알고리즘을 이용하여 쾌적성 평가 실험을 수행하였으며, 전두엽의 a파 전력비(power ratio)를 이용한 기존의 감성 평가 방법과 성능을 비교해 보았다. 온도와 습도를 이용한 쾌적성 평가를 위해 여러 방법으로 수집된 뇌파를 통해 적은 채널을 이용하면서 감성을 평가할 수 있는 전극의 위치를 확인하고자 실시한 여러 가지 조합의 2채널, 4채널 실험에서는 쾌적성 평가 결과가 제시한 task와 80%가 일치하여 Heller의 감정 모델에 근거한 4채널이 가장 변별력을 나타내는 전극의 위치임을 알 수 있었다. 또한 기존의 a파 전력을 통하여 뇌의 활성 영역을 구분하여 감성을 평가하는 방법에서는 상당히 저조한 성능을 나타내어 감성과의 상관성을 확인할 수 없었다.

Lighting in indoor space is being changed to system lighting converged with IT technology. Office space lighting with incandescent lamps and fluorescent lamps was completed through overall lighting plan by illumination in most cases, but convergence between LED lighting and IT technology enables the technology of responding to user requirements to be realized. Optical physical quantity suitable for humans and the lighting environment in accordance with user's sensibility, based on space function and user's behavior, would contribute to the improvement of service productivity, energy reduction, and enhancement of emotional satisfaction by providing user optimized lighting solution. Thus, user-customized system lighting guidelines to be applied with integration indicators of optics and sensibility are required. For the design elements required by users, environmental factors, product characteristics, optical characteristics, and sensibility factors are drawn from the design cases for office space and the survey, and the design check list and evaluation indicators are considered to reflect the requirements in the design and requirement indicators to give integrated satisfaction for optics and sensibility are developed. Purpose-centered design method from the user's viewpoint is applied to function-focused design through scenario, and it should be applied flexibly, as the new lightning design method solutions, to the concept design stage of space lighting design and device development. This paper, therefore, presents user-customized guidelines by pursuing the optics and sensibility evaluation and design method combining the requirement conditions and scenario, to be used for lighting content development and design.

The purpose of this study is to investigate hand and sensibility of PET treated by Ultra-Violet (UV). The 4-channel PET knit fabric was treated by a self-made UV instrument in 5cm distance with different time frames-0min, 30min, and 90min. For hand evaluation, mechanical properties were measured by the KES-FB system. The environmental condition was controlled at 29$^{\circ}C$, 75% (R.H.)-summer standard climate. Twenty female students evaluated 'roughness', 'smoothness', 'wetness', 'stiffness', 'coolness', 'touch', 'preference', and 'comfort'. The outcomes of the experiment are as follows: The surface roughness of mechanical properties showed significant differences and the value of PET irradiated by UV for 90min was highest. The order of primary hand value such as NUMERI and FUKURAMI was in a following order-Untreated > 30min treated > 90min treated. Total hand value showed that PET irradiated by UV for 90min was appropriate for using summer fabric. The results of subjective sensibility were that the untreated and 30min treated PET were recognized as similar and had a good evaluation on 'comfort', 'preference' and 'the sense of touch'. This consequence disagreed with total hand value, because it was considered that subjects' hand sensibility was dependent on the feel of smoothness.

Simulators have been used to evaluate drivers'reactions to various transportation products. Most researches, however, have been concentrated on their technical performance, thus this paper considers drivers'senses of moving on a vehicle simulator through the analysis of human sensibility ergonomics. A sensibility ergonomic method is proposed in order to improve the faithfulness of vehicle simulators. A simulator of passenger vehicle consists of such three modules as vehicle dynamics, virtual environment, and motion representation modules. To evaluate drivers'feedback, human feelings are categorized into a set verbal expressions collected and investigated to find the most appropriate ones for translational and angular accelerations of the simulator The cutoff frequency of the washout alter ill the representation module is selected as one sensibility factor Sensibility experiments were carried out to find correlation between the expressions and the cut-off frequency of the filter. This study suggests a methodology to obtain an ergonomic database which can be applied to the sensibility evaluation of dynamic simulators.

Human Sensibility Engineering System (HSES) has been applied to product development for customer's satisfaction based on ergonomic technology. The system is composed of three parts such as human sensibility analysis, inference mechanism, and presentation technologies. Inference mechanism translating human sensibility into design elements plays an important role in the HSES. In this paper, we propose a rule-based inference model for HSES. The rule-based inference model is composed of five rules and two inference approaches. Each of these rules reasons the design elements for selected human sensibility words with the decision variables from regression analysis in terms of forward inference. These results are evaluated by means of backward inference. By comparing the evaluation results, the inference model decides on product design elements which are closer to the customer's feeling and emotion. Finally, simulation results are tested statistically in order to ascertain the validity of the model.

Psychological and physiological effects of the simulator sickness could be important bias factors for the sensibility evaluation. The purpose of the present study was to clear the differences of psychophysiological responses due to individual sensitivity of simulator sickness. The present experiment tried to investigate the simulator sickness objectively by observing the change of the simulator sickness for the different level of sickness groups (sick and non_sick group). The subjective evaluations using Simulator Sickness Questionnaire (SSQ) and physiological responses were measured every five minutes when they were driving as 60km/h in the driving graphic simulator. Response level of the subjective evaluation for all subjects on the simulator sickness was linearly increased with time for every item, and the response level of sick group was bigger than that of non_sick group. When the analysis on central nervous system was done separately on the sick and the non_sick group, there was significant difference in the parameter $\theta$/total at Fz and Cz. Although the analysis on autonomic nervous system for all subjects showed the increased activation of sympathetic nervous system, there was no significant difference between the sick and non_sick group. In summary, it is necessary to select the subjects who feel less simulator sickness in order to be accurate sensibility evaluation. The parameters to distinguish between the sick and non_sick group were the change on $\theta$/total and subjective evaluation using SSQ.

In our life, we have used many digital appliances. They help us to improve the quality of life but sometimes give us unsatisfactory result. Because they produce specific noise. Especially vacuum cleaner produce much noise that is very annoying. So we need to study what sound metrics affect human sensibility. In this paper, we develop sound quality index for vacuum cleaner using the sound quality metrics defined in psychoacoustics. First, we carry out the subjective evaluation of vacuum cleaner sound to verify what vacuum sound feels good to human. And then artificial neural network estimated the complexity and the nonlinear characteristics of the relations between subjective evaluation and sound metrics. Finally the ANN is trained repeatedly to have a good performance for sound qualify index of the vacuum cleaner. As a result, the sound quality index of vacuum cleaner has a correlation of $93.5\%$ between the subjective evaluation and ANN. So, there exist three factors that Is loudness, sharpness, roughness which affect the sound quality of vacuum cleaner.

This paper is to study pertinent consumer evaluations and preferences of fashion depending upon human sensibility. Focus is placed on quantifying consumer's sensibility through the sensibility analysis of men's fashion. The subject are 227 male and female university students of who take the course of "Modern Life and Fashion" and "Understanding of Colors" in the OCU Cyber University. Data has been collected by survey method and subsequently analyzed and interpreted. To measure consumer's consuming sensibility, G-Sensibility tool developed by 'Fuji Central Institute' has been employed. The results of the analysis of ANOVA and MANOVA show significant differences among the following 5 styles: Active style G2, Open-minded style of G-3, Mania style of G4, Sensitive and emotional style of G5. According to ${\chi}^2$ test, the results show that the distinction of sex and their interests in fashion are significant different. The evaluation of men's fashion, according to Multi-dimensional test, shows a variety of differences according gender and G sensibility styles. These varied distinctions are illustrated statistical in Picture 1, Picture 2, Picture 3, Picture 4, Picture 8, and picture 10. Based art the results, a follow-up study to develop the case study and the apply it's results are recommended to produce products placed in the market.
