The purpose of this study is to understand human sensory and emotional response according to car noise. This study investigated human stress levels from car noise based on the data of electro-encephalogram (EEG) and subjective evaluation analysis data. Since there are few previous works on the effect of car noise on human's reaction, more profound research about the effect of car noise on driver's emotion would be worth performing. Subjects were exposed to five different kinds of car noises. EEG data were collected while the subject was exposed to noise. In order to process EEG data, FFT analysis was used to separate the collected EEG data into ${\alpha}$-wave and ${\beta}$-wave. Also, survey was performed to carry out subjective evaluation. The results of the subjective evaluation were closely correlated to those found in the EEG signal analysis. The results from this study may provide useful information for mitigating car noise induced stress.

In recent years, the visual characteristics of natural open space and greenbelt surrounding the urban landscapes have been changed with sprawling of residential areas and highrised residential buildings. Since these natural areas being the background element of residential areas are topographically sloped mountains in many cities. It is easy to be seen in the distance and it is important to preserve these areas as a visual infrastructure of the urban landscape. The purposes of this study are to extract the factors of landscape impact evaluation for these areas and to clarify the physical landscape variables representing these factors, and to infer the visual-perceptional relationships between image and landscape variables. As results, conceptional three factors were extracted with semantic differential evaluation to classified 18 landscape slide, and three regression models were established with factor score of landscapes and physical variables measured in photographs. On the basis of these relationships, visual-perceptional characteristics were discussed by analyzing the data form eye-movement recording to each of landscapes. The factors of "spatial unfolding of backdropped hilly greenspace", "horizontal quence of residential buildings", and "landscape complexity" prove to be important. And it prove important variables of "skyline of mountainous ridge" and "visual edge of building structure" in regression models and eye fixation movements.

The purpose of this study is to objectively explain the visual sensibility of clothing pattern and develop the design of clothing pattern that satisfies the consumer's sensibility. The photos stimuli on clothing pattern are divided into source, presentation, layout and are composed of each 6 photos per chapter totally 48 photos and semantic differential bi-polar scales are consist of 27 couples sensibility words. The subjects were 400 females in the twenties. Data were analyzed by SAS. The major finds were as follows: 1. As a result of the factor analysis, 4 factors of visual sensibility were consist of Coordination, Hardness and Softness, Attention, Rhythm. 2. As to the difference of visual sensibility based on the composition of clothing pattern, there were differences Hardness and Softness, Rhythm by source and there were significant differences among 4 factors by presentation and layout. 3. According to the age and education level, there were significant differences in Attention, Rhythm and according to the consuming areas, there were significant differences in Coordination, Rhythm. 4. According to sensibility positioning, The clothing pattern was classified as soft-hard, simple-complicated. 5. As a result of the regression analysis, preference, consuming desire and satisfaction appears to be closely related. Good quality is related with total clothing image which is brought about composition of clothing pattern.

This study evaluated the characteristics and sensibility of work clothes materials developed that took into account the work environment of major industrial settings, for which a selection was made according to spring/autumn use and winter use. The physical properties of the existing and test weaving of the work clothes materials were compared after the test weaving of work clothes materials through material design, which altered the yarn count, composition, weave and density of material. To evaluate sensibility of work clothes materials subjectively, seven ranks' semantic differential scale questions were developed with polar adjective pairs. The test weaving of work clothes materials showed improved performance (such as tensile strength, dimensional change, water vapor permeability, and color fastness) compared to the existing materials. The common factor analysis indicated that the explanatory power of the cumulative variance for the spring/autumn use and winter use was 71.19% and 69.53%, respectively.

The dimensional structure of impression formed of a female figure in specific attire was identified and significant influence of skirt length and suit color on impression formed of figures in suits were researched in the part I of this study. In part ll, the effect of identical elements of apparel design on impression formation of a female figure in dress and pants- blouse were studied. The experimental matirals consisted of two sets of stimuli and 7 point semantic differential response scale developed in part 1. Each set of stimuli was composed of 20 drawings representing female figures in each attire. Three independent variables, which were the length of bottom, color of dress or pants and collar type of blouse, were manipulated in each stimulus. The experiment was arranged by 3 factorial design, and the data were analyzed by 3-way ANOVA and by Multiple Classification Analysis. To summarize, in impression formation of figure in dress, the most dominant design element was identified as bottom length and the second most dominant one was color of dress. In contrast, in perception of figure in pants-blouse, the most important design element was color of pants and secondly important one was bottom length. The collar type of top didn't have critical effect on impression formation of figures in both type of attire.

This research compares the difference of each preference segments' subjective hands and sensibilities in order to analyze the correlations among preference, subjective hands, and sensibilities. Preference segments were classified into wool, acrylic, and long stitch length-preferred clusters in previous research. To evaluate the subjective hands and sensibilities of knit fabrics, the 20's and 30's women rated twelve knit fabrics by touching, using a questionnaire with a seven-point semantic differential scale. These twelve knit fabrics were differentiated by controlling the mixture ratio and stitch length using a computer-controlled automatic flat knit machine. The difference of each preference segments' subjective hands and sensibilities was determined using the conjoint analysis. The clusters perceived the subjective hands and sensibilities differently according to preferred constituent characteristics. There was no correlation between surface unevenness and preference in wool-preferred cluster, while there were negative correlations in other clusters. The acrylic-preferred cluster had a preference in coolness compared to other clusters; in addition, the long stitch-preferred cluster preferred flexibility/bulkiness and extensibility than the others. All clusters preferred modem and natural sensibilities that were caused by different constituent characteristics of knit fabrics.

In recently, Is inhabiting more than 70％ indoors during a day in case of company employee and ordinary people which is looking at usual business. Therefore Thermal comfort of human body about indoor temperature and air flow acting very heftily. When intestine temperature is fallen for external low temperature and air flow in winter in case enter into heated room feel comfort by effect of temperature and feel comfort or discomfort by room heating condition gradually. Therefore it is important that grasp thermal comfort about temperature and air flow in heating to keep continuous comfort in indoor dwelling. Temperature and thermal comfort factor of emotion ＆ sensitivity image exert fair effect since heating middle although thermal comfort change greatly effect on sensation about temperature at actuality heating early. Need much study yet in vantage point of emotion ＆ sensitivity although much study were held about thermal and comfort sensibility and when heat in existing research until now. Therefore this study is targeting that evaluate thermal comfort through introduction of estimation method by emotion ＆ sensibility image real and synthetic sensibility about thermal environment that is becoming winter heating.

The present study was performed to investigate the psychological effects of spring flowers blossoms, which is one of the elements influencing to human psychology, in order to provide scientific evidence on the psychological benefits of green plants. A self-reporting survey was conducted by using self reporting questionnaires on the impression (semantic differential method: SD method) and mood states (profile of mood states: POMS) of eighty university students in their twenties. Korean forsythia, Korean rosebay, Japanese apricot, Cherry blossom, and Magnolia were chosen as spring flowers. The results of impression evaluation and mood states changes showed that spring flower blossom had beautiful, soft, warm, moist, familiar and full impressions, and changed our mood positively by reducing depression and anger, or by increasing vigor. In addition, different psychological effects can be differently observed depending on the species; for example, Cherry blossom had a greater effect in changing the impression and feeling than others. The findings would provide support toward the active usage in green space as well as its design maximizing the psychological effects of nature.

The purpose of this study was to investigate the adolescents' images and preference on cultural products based on Baekje traditional culture focused on adolescents. The subjects were 421 adolescents in Daejeon and Chungnam province. The measuring instruments was stimuli of cultural products and a questionnaire with semantic differential scales of image of cultural products, preference, product evaluation criteria, and subjects' demographics characteristics. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, t-test, ANOVA, Duncan's multiple range test, and regression analysis using SPSS program. The results were as follows. First, 3 factors(attractiveness, interest, gentleness) were emerged on images of cultural products based on Baekje tradition culture, however, the current products could not convey affectively the attractive and gentle image of baekje traditional culture. Second, the preference of the Baekje cultural products was evaluated low, and especially design and price was rated low in the evaluation criteria. Third, preference was related with the 3 image factors, and attractiveness factor was showed highly positive effects on preference of cultural products. The implication of this study was to provide the useful cultural product development plan for adolescents, and the research results suggested that modern and individual design, unique traditional pattern, resonable price, and practicality have to be considered to develop successful cultural products for adolescents.
