  • This study examines psycho-physiological effects of visual perception in super-high rise apartment exterior space. Theoretical research was used to explain the psycho-physiological effect of visual perception and case study was carried out to evaluate the physiological response of the subjects. For the physiological evaluation, six slides were chosen and the EEG was used. According to the results of the case study, the central nerve was activated by the slides with pleasant scenic views. In shows that the scenery composed of natural scenic elements effects psychological condition positively. Scenic views with natural scenery have a direct correlation with positive attitude. In conclusion, the results of this study show that the exterior space should contain natural scenic view to help users decrease their visual stress.

  • Human sensibility is assessed by measuring and analyzing various physiological signals in an objective way, or by analyzing adjectives chosen by the subjects in a subjective way. The present study aims at developing an integrated human sensibility assessment system that measures changes in a person's objective and subjective sensibility in real-time and analyzes them in an integrative way. The present system is composed of a real-time subjective sensibility assessment system, an automatic subjective sensibility assessment system and a real-time physiological signal measurement and analysis system for sensibility assessment, which are separated from one another. It can be utilized individually, or can be combined as a synthetic sensibility assessment system for comprehensive sensibility assessment.

  • Using eye mark recorder and polygraph, basic laboratory experiments have been conducted to investigate the validity of psycho-physiological measures to the analysis of on-line cognitive information characteristics at man-machine interface (MMI). It is concluded that various psycho-physiological measures are useful to estimate various aspects of human cognitive characteristics and thus to the evaluation of MMI designing from the viewpoint of its harmony to the human cognitives.

For the physiological evaluation, two simulations with sign and color sample were chosen and the EEG was Used. Data were collected from May 15th. to June 15th. The subjects were 20 students of architecture department and frequency, percentage, ANOVA, T-test, multiple comparisons were used for data analysis.

  • Paraphilia and paraphilic disorder is one of mental disorders making it difficult to assess and treat. Recently, a number of methods for assessing the paraphilia are being developed gradually outside south Korea. And the reliability and validity of various assessment tools are being reported. The standardization of the assessments and questionnaires was not made yet. For assessment of paraphilia that has been reported from abroad, the author comprehensively organized clinical interview, physical examination, psycho-physiological methods, self-reporting scale of sexual thoughts, fantasies and attitudes and multiple self-reporting scale of sexual interests and described the clinical significance of the assessment tools. The national standardization of both self-reported questionnaire and physical evaluations is expected to be completed later.

  • The main purpose of this research is to develop the methodology of objective evaluation of clothing appearance by eye movement analysis. The visual clothing items used in this study were skirt, one-piece, pants and shirt with the style variation of silhouette and details. By observing eye movement during visual evaluation of clothing, we can achieve the basic fixation data of eye movement. Moreover, we developed the Matlab program to extract the fixation coordinate and number of eye fixation on each part of the clothing item. As results, there were differences in the duration of fixation time for each item and the fixation time was not different by styles within a clothing item. However, we could find differences in the fixation time within a style, in other words, we could select the important parts of the clothing by observing the fixation time in a certain clothing item. It is also noted that time required in visual information processing differs depending on the item, and there was a region which contain more information independent with styles in the same item. By developing the objective method of visual evaluation that correspond to human's visual information processing, the results are expected to be applied in the retrieval program in internet shopping mall or in the development of contents for advertisement of clothing.

  • The sense of touch has both objective and subjective characteristics. During hand evaluation of the fabrics. psycho physiological processes such as emotion and stimulation. On other site, the mode of touch (passive vs. active) is also capable to modulate somatosensory responses. I.e., suppress somatocensory perception during active electrocortical responses to passive and active touch of the textiles with different subjective emotional preference. The study was carried out on 36 female college students. Physiological signals were acquired by Grass and BIOPAC 100 systems with AcqKnowledge variables, namely heart rate (HR), respiratory sinus arrhythmia (RSA), pulse transit time (PTT), respiration rate (RSP) and skin conductance parameters (SCL, amplitude, risetime and number of SCRs) were analyzed for baseline and stimulation conditions. Analysis was manifested in a form of moderate HR acceleration. RSP increase, RSA decrease (lowered vagal tone), decreased PTT and increased electrodermal activity (increased SCL, several SCRs) that reflects general sympathetic activation. Parietal EEG effects (on contra-lateral side to stimulated hand)were featured by short-term alpha-blocking, slightly reduced theta, significantly increased delta and enhanced fast beta activity with few variations across stimuli. The main finding of the study was that most and least preferred textures exhibited significant differences in autonomic (HR, RSP, PTT, SCR, and at less extent in RSA and SCL) and electrocortical responses (delta, slow and fast alpha, fast beta relative power). These differences were recorded both in passive and active stimulation modes, thus demonstrating reproducibility of distinction between most and least emotionally preferred tactile stimuli, suggesting influence of psychological factors, such as emotional property of stimulus, on physiological outcome.

  • The purpose of this study was to compare the subjective fabric hand evaluation and wear comfort of PET treated by Ultraviolet and to evaluate the subjective results from the investigation of microclimate temperature. The subjective hand evaluation was performed by 20 subjects (age: 20-25) with 5-point scale questionnaires to investigate the change of PET knit fabrics treated for different times, specifically, 0, 30 and 90 minutes. The questionnaires were composite with 8 questions; roughness, smoothness, wetness, stiffness, coolness, touch, preference, and comfort. In order to evaluate sensations of wear comfort, we made garments with UV treated fabric and five female students were tested. They walked at the speed of 6.7 km/ hr for 15 minutes in an environment, which was controlled at $29^{\circ}C,\;75{\pm}5%$ RH. Before and after exercising, the microclimate under clothing and subjective wear comfort was measured. The results of subjective evaluation of fabric hand were that untreated and treated for 30 minutes PET were recognized as similar and have a good evaluation on comfort, preference, and touch. According to the result of wear comfort, clothing treated by UV for 90 minutes had the lowest value on the thermal and humidity sensations. In addition, the value of tactile and comfort sensation was the highest on the clothing treated by UV for 90 minutes. In the case of objective evaluation, PET treated for 90 minutes was the lowest on microclimate humidity. PET irradiated by UV for 90 minutes was more 'cool' in thermal sensation and more 'dry' in wet sensation. Accordingly, it was consistent with the result of subjective wear comfort.
