The purpose of this study is to investigate the preference of the hand and the sensibility image of underwear textiles according to seasons. According to a recent survey of 109 college students, using a 7 scale evaluation to the preference of the hand and the sensibility image among 13 summer and 10 winter underwear textiles. The data was analyzed through mean, SD, factor analysis, t-test, Person correlation analysis and regression analysis using SPSS Win 11.0. The summer underwear textiles were classified according to six tactile factors: stiffness/surface unevenness, weight, elasticity, moistness, extension, and warm-cool and 3 sensibility image factors: elegant individual, modern, and sporty-casual. The winter textiles were classified according to six tactile factors: stiffness/surface unevenness, elasticity, warm-cool, drapability, moistness and flexibility and divided into 2 sensibility images: modern elegant and sporty-casual. Factors expressing hand and sensibility image according to season showed significant difference. In the summer, weight, in the winter, drapability and flexibility showed significant difference at the hand factor evaluation. The hand factors: weight, warm-cool and modern sensibility image factors effect the preference of summer underwear textile, also the hand factors-elasticity, stiffness/surface unevenness and the sensibility image factor-easy-sport-casual-effect the preference of winter textiles. Therefore, the thin, light, and cool textiles which are also gorgeous and sporty-casual are preferred for summer underwear textiles while soft, simple and comfortable textiles are preferred for winter textiles.

This paper represents the development of an array-type flexible tactile sensor using PVDF(polyvinylidene fluoride) film and flexible circuitry. The tactile sensor which has $8{\times}8$ taxels is made by using PVDF film and FPC(flexible printed circuit) technique. Experimental results on static and dynamic properties are obtained by applying arbitrary forces and frequencies generated by the shaker. In the static characteristics, the threshold and the linearity of the sensor are investigated. Also dynamic response of the sensor subjected to the variable frequencies is examined. The signals of a contact force to the tactile sensor are sensed and processed in the DSP system in which the signals are digitalized and filtered. Finally, the signals are integrated for taking the force profile. The processed signals of the outputs of the sensor are visualized on a personal computer, the shape and force distribution of the contacted object are obtained using two and three-dimensional image in real time. The reasonable performance for the detection of contact state is verified through the experiment.

In this study, differences of texture image and preference for men's suit fabrics according to mechanical properties, hand and fabric information were investigated. 55 subjects evaluated texture image and preference of 12 kinds of wool blended fabrics. For statistical analysis, t-test and pearson correlation coefficients were used. The results were as follows: Most of mechanical properties effected on texture images, and bending property and shearing property were effected on tactile preference and purchasing preference. For hand, objective hand values showed correlations with subjective texture images and preferences, but THV had almost no correlations. In sensory images according to presence of fabric information, fabrics were evaluated thinner, lighter, more pliable and smooth by cognition of wool blending ratio. For sensibility images, fabrics were evaluated more refined, intellectual, dignified and less practicable after recognize of wool blending ratio. In preferences, tactile preference was increased and purchasing preference was decreased after recognize fabric information. Therefore, significant differences of texture image and preference were observed according to presence of fabric information.

This paper presents a finger-shaped multisensor system which can measure the tyep and position of a target surface by contactl. The multi-sensor system consists of a sphere-shpaed optical tactile sensor located at the finger tip and a force/torque sensor located at the joint of a finger. The optial tactile sensor determines the type and position of the target surface using the shape and position of the CCD image of the touching area generated by a contact between the sensor and the taget surface. The force/torque sensor also determines the position and surface normal vector by applying the distributionof forces and torques t the contact point to the equations of finger shape. The measurements on the position and surface normal vector at a contact point obtined by two individual sensors are fused using a statistical method. The integrated sensor system has 0.8mm error in position measurement and 1.31$^{\circ}$ error in normal vector measurement. The developed sensor system has many applications, such as autonomous compliance control, automatic grasping and recognition, etc.

This study finds information about the image and improvements of hiking gear and examines the influence of heat moisture, psychology, tactile sensation, and mobility/pressure related properties on wear comfort. The relationships of the four related properties and personal characteristics (such as sex, age, BMI and sensitivity) were also checked. Questionnaires were distributed to 400 people in their 40s and 50s; subsequently, 260 were used for data analysis. The questionnaires were comprised of questions about the general hiking characteristics, images and improvements in hiking gear, influence of the four properties on wear comfort, and demographic characteristics. Data were analyzed by frequency analysis, correlation analysis, ANOVA, T-test using SPSS 21 IBM for Windows. The results of this study are as follows. It was shown that people in their 40s and 50s usually went hiking two to four hours with friends or family once to three times a month. Jacket had the largest number of wearing frequency, followed by pants, t-shirts, and inner wear. Consumers' images of hiking gear were positive and the demands for improvements in hiking gear were price, unique design, and vivid color. The order of influence of the four properties on wear comfort was heat moisture, mobility/pressure, tactile sensation, and psychology related properties. The four properties of wear comfort were not influenced significantly by consumer sex, age, BMI, and sensibility.

In this research, we investigated the university students' consciousness and preference for the jacquard fabrics and developed the evaluation scale of the sensibility of jacquard fabrics appied by Korean traditional motives. 23 jacquard fabrics were assessed subjectively by 466 consumers using the 7-point scale of 23 descriptors of texture sensibility and 50 descriptors image sensibility. The percentage of students who were interested in jacquard fabrics was similar as that of students who were uninterested. 75.3% of students were shown to think that it was necessary to apply Korean traditional motives to the jacquard fabrics. Through cluster analysis, the hierarchy of the image sensibility was examined. The tactile sensibility of jacquard fabrics were classified into 9 sub-clusters, image sensibility of them were classified into 14 sub-clusters. The dimensions evaluating the image sensibility of jacquard fabrics were developed using multi-dimensional scaling method. A 3-dimensions and 6-axes system were determined, which consisted of 'classic-modern', 'splendid-plain', 'abstract-realistic'. It was shown that preference of jacquard fabrics was increased, as image sensibility such as 'various', 'gorgeouse', 'beautiful', 'mild', 'dim', 'traditional', 'orderly', 'comfortable', 'dignified', 'abundant', 'fantastic', and 'vague' were increased and those such as 'intense', 'old', 'stuffy', 'exotic' and 'static' were decreased.

The purpose of this research was to examine the subjective evaluation of sensory images and preferences according to the mechanical properties of linen and ramie fabrics for summer shirts. 54 male and female teachers evaluated the sensory images and preferences of 6 specimens of linen and ramie fabrics sold on the market. For statistical analysis, factor analysis, Mann-Whitney and Kruskal-Wallis test, Pearson correlation, and regression were used. The results were as follows: The sensory images of shirt fabrics were classified into 5 factors: 'smoothness', 'stiffness', 'elasticity', 'dry/coolness', and 'wetness'. There were partially significant differences by the gender and age in the sensory images for the shirt fabrics. Females were more sensitive than males for the 'stiffness', 'elasticity', and 'wetness' factor and the evaluators in their 20's felt fabrics were stiffer. The sensory images showed many correlations with the mechanical properties of fabric mostly. The preferences of tactile and purchase were no different according to the gender and age. They preferred a thin and soft sensory image as like ramie/cotton blended fabric and bamboo fabric for summer shirts. The significant sensory image factors affecting tactile preference were 'smoothness', 'dry/coolness', and 'elasticity', and the ones affecting purchase preference were 'smoothness', 'stiffness', 'dry/coolness', and 'elasticity'. W, WT, MMD, and G properties of the mechanical properties of fabrics affected the tactile preference for summer shirt fabrics.

우리가 살고 있는 현 시대의 뉴미디어는 다감각적 테크놀로지에 의해 강하게 수용자를 현혹시키며 우리의 삶에 영향을 미친다. 그것들은 시각적으로 구성되어 있음에도 불구하고 마치 촉각적으로 체험하는 듯한 느낌을 준다. 현대의 대중은 온라인 미디어의 확산과 함께 일상 속에서 모든 감각을 통해 미디어를 접하고 있으며, 그 과정에서 일시적이면서도 촉감각적인 공유를 원한다. 이와 같은 흐름으로 대중사회와 영화의 출현이후, 예술은 분산적이고 촉각적인 지각방식에 호소하여 왔으며, 이 대중 적인 지각방식은 특히나 온라인 게임문화의 발달과 함께 일상 속에서 '시각적 촉지각'의 체험을 가능하게 한다. 온라인 게임의 서사를 체험할 수 있게 제작된 게임 애니메이션의 편집이 주는 쇼크작용은 바로 시각성에 촉각성을 불러일으킨다. 이러한 가정 하에 본 연구는 발터벤야민의 시각적 촉각성 이론과 영상의 몽타주 이론을 근거로 하여 게임 애니메이션을 접하는 대중의 촉각적인 충격이 단순한 그래픽 효과만이 아닌 몽타주 효과와 분산적인 수용에 의해 이루어진다는 것을 앞의 이론을 근거로 하여 설명하고자 한다.
