Purposes of this study were firstly to refine the measurement technique of tactile sensation and sensibility induced by touching the fabrics and secondly to investigate the differences of tactile sensibility depending on environmental conditions and the type of polyester fabrics. The environmental conditions were controlled at 20$\pm$1$^{\circ}C$, 65$\pm$3%RH(standard) and at 29$\pm$1$^{\circ}C$, 75$\pm$3%RH(warm & humid). As results, three factors were extracted from factor analysis of sensory assessment scale. The first factor was thickness and weight, the second one was surface-related property and the third one was stiffness in both environments. Depending on the environmental conditions, heat and moisture-related sensations such as [cold], [damp] and [dry & drapable] were affected significantly. Regression equations with the sensation descriptors were developed for the prediction of tactile sensibility(R2>.89). While the most efficient descriptor was [thin & flexible] in the standard environmental conditions, that was [dry & drapable] in the warm & humid environmental condition.

Information gathered through experience transforms into knowledge and such knowledge becomes a foundation for intuitive decisions. Based on such background, the following study investigates intuitive decision making on basic elements needed for design concepts and visual conceptualizations. The study consist two phases. first, 12 structural elements of a digital camera and relation between each elements were arranged intuitively on a board. Next, sketches were generated with relationship of structural elements in mind. As a result of the study, concept with intuitive decisions effect structural thinking, various developments, specific operation methods , and sketch expressions. However, study also revealed that the freedom of human emotions don't accord with the qualification map.

사회와 생활수준의 발달로 인간은 자연환경하에서 생활보다 인공적 환경하에서의 생활이 증가하게 되었다. 따라서 인간은 쾌적한 생활공간을 요구하게 되었고 이를 위한 온열환경에 대한 연구가 진행되어져 왔다. 이러한 생활공간에서의 쾌적한 온열환경에 영향을 주는 물리적 요인으로는 온도와 습도 그리고 기류 등이 있다. 또한 온열환경에 대한 인간의 감성적 측면도 쾌적한 온열환경을 결정하는데 중요한 역할을 한다. 본 연구에서는 겨울철 대류난방시 인간에게 가장 쾌적한 환경을 제시할 수 있는 기류 속도의 범위를 찾고, 이를 평가하는데 객관적인 지표를 설정하기 위해 온도에 따른 기류조건을 제시하고, HRV 분석을 통하여 인체의 자율신경계의 변화를 관찰하였다. 실험결과 18$^{\circ}C$, 21$^{\circ}C$, 24$^{\circ}C$ 각각의 온도에서 draft를 초래하지 않는 0.15m/sec의 기류속도일 때 가장 높은 MF/(LF+HF) 값을 보여 쾌적한 기류조건으로 나타났고 이는 쾌불쾌감신고(CSV)와 동일한 결과를 나타내었다. 이러한 심전도 신호를 통한 HRV 분석은 기류조건에 따른 온열쾌적성의 평가에도 객관적이고 신뢰성 있는 지표로 제시될 수 있을 것이다. 또한 다른 환경하에서의 감성평가 척도로도 이용될 수 있을 것이라고 생각되어진다.

This study was proposed as an exploratory study for understanding the biological bases and structures of three personality models: Eysenck's PEN model, Gray's BIS/BAS model, and Costa & McCrae's Five Factor Model, which was chosen as the major descriptive model regardless of its biological bases. Besides, Eysenck's impulsivity scale, IVE, was added to demonstrate the relationship of P and impulsivity. Concerning personality, most previous reports have explored the relationships between P300 and the introversion-extraversion of Eysenck's theory because of its putative biological bases. In the present study, forty-eight undergraduate took four personality batteries (ERQ-R, NEO-Pl-R, BIS/BAS, and IVE). Two types of oddball tasks including different stimulus duration were used to induce ERPs (50ms for task 1, 300ms for task 2). Distributional topographies of correlation coefficients with personality traits and ERP components were drawn, and considered for the consistent interpretation of the personality model structures. Even though all equivalences for extraversion of personality batteries showed similarities for their intra-correlation, their correlations with P3 amplitudes were dissociate. Eysenck's E might not be the proper psychometric measure for elucidating its biological bases. The present study supported the negative relationship of P3 amplitude and extraversion, which is the consensus of previous studies. Neuroticism and Psychoticism showed correlations with the earlier sensory processing components such as N1 and P2. This result might explain the reason why most of studies have failed to find biological connections relating them. Interaction between gender and personality traits should be considered for the interpretation of correlations. Two types of auditory stimulus duration had different sensitivity to personality traits.

Despite the substantial changes made in the product design field to adopt light as an essential design element, there has been little effort to define how customers respond emotionally to the light design of products. Therefore, it is necessary to analyze the emotional effect of light as a new design element. However, previous research focuses solely on deriving optimal lighting conditions to achieve particular emotional effects. Therefore, this paper investigates the customers' desired emotional effects of product's light design. We studied refrigerators that utilize light as the main design element of the product. We applied mixed methods by combining close-ended questions and open-ended question to efficiently derive the desired emotion. Participants were asked to choose the most favorable refrigerator image in each of the twelve image groups and indicate why they choose that image with the short-answer survey form. Approximately one thousand terms were collected, and those terms were classified into 29 groups using thesaurus relationships. The term groups were again classified into the four big emotion categories and labelled as "abstract quality," "light property," "space perception," and "visual comfort." Also, a model of the relationship between desired light style and light properties was proposed, since we observed the light properties related to three other categories. This study used mixed methods to identify the emotional value of a new design element. We suggest that the emotional categories derived and the proposed relationship model could be used to evaluate the product's light design.

Emotional design gets more and more important. However, the systematical approaches to integration of user experience elements in product design have been rarely tried. This study consists of three parts. We extracted affective words fitting to design direction based on trend analysis. Then, user experience elements were matched with affective words. Finally, a prototype system was made to guide designing affective factors in electronic products. In the present study, user experience elements were defined as color, material & finishing, and sound. Through various documents analysis and trend analysis, trend analysis experts and user experience designers extracted 31 affective keywords which could fully reflect current trend. After paired-comparison of selected keywords, 2 sensibility dimensions were obtained by multidimensional scaling. Trend affective keywords could be explained by 2 dimensions of human-centered' vs. 'techno-centered' and 'warm vs. cool'. Next, user experience elements stimuli were matched with each keyword by user direct positioning on the 2 dimensions affective map. Based on the result of the experiment, the prototype system was developed for the product designers. The results of the current study could guide designers to design emotionally satisfactory products.

According as the quality of life is improved along with economic growth, in the road plan and design sector also, it is now progressed that function oriented design is changed into the landscape oriented design that considers eyesight and emotion, which are psychological properties of users. Accordingly this study tries to come up with reasonable and objective methods to extract various emotional adjectives, which were found by the survey, while minimizing difference among characteristics of emotion and cognition of individuals. First, given semantic differential, based on various emotional adjectives that were found through the survey with the scale up to five points, the author extracted representative emotional adjectives through an element analysis, which is a conventional method of the previous research, and through an identification analysis which is suggested by this study, and then established model I of Quantification. And by using the established quantification model, the author presumed satisfaction degree, and through verifying pair wise comparison with actual satisfaction degree, the author found the results from identification and correlation analysis methods are most similar to actual satisfaction degree. As a result, the author could check the above emotional and correlation analyses were appropriate methods for comprehending which emotional elements are applicable when a continuous road landscape is designed by identification and correlation analyses.

This research was performed to confirm the four emotional eating types and examine the differences in BMI, ego resilience, and the level of college adaptation among those types. The total of 485 Korean college students (male 249, female 236) participated in this study. The main results were as follows, First, the emotional eating types were divided into four types based on positive emotional eating and negative emotional eating, and the type of more - eating with positive emotion and less? eating with negative emotion was the largest one among all the types. Second, there were no significant distinctions on frequency between emotional eating types and BMI. Third, individuals with less - eating for both positive and negative emotions showed the highest ego resilience level, whereas those with more - eating for both positive and negative emotions showed the lowest. Fourth, individuals with less - eating for both positive and negative emotions showed the highest score in the level of adaptation in college whereas those with more - eating for negative emotion and less - eating for positive emotion showed the lowest. Limitations of the present study and suggestions for future research were discussed.
