시상은 체감각 정보를 처리하는데 있어서 매우 중요한 역할을 하는 부위이다. 본 연구는 운동장애 환자의 시상에서 뉴론의 활동 특성을 알아보기 위해 수행되었다. 그 결과 체감각으로서의 운동자극에 반응하는 뉴론이 essential tremor (ET) 환자의 nucleus ventralis intermedius (VIM)에서 발견되었다. ET 환자 뉴론의 평균 활동율(firing rate)은 Parkinson's disease (PD) 환자 보다 높았다. 또한 ET 환자의 VIM에서 운동자극에 반응하는 뉴론의 평균 활동율은 PD 환자 보다 높았다. 하지만 촉각자극(touch)에 반응하는 nucleus ventralis caudalis (VC) 뉴론의 활동율은 ET와 PD 집단간에 차가 없었다. Bursting activity를 나타내는 뉴론은 nucleus ventralis oralis anterior (VOP)에서 ET집단이 PD 집단보다 적었다. tremor cell은 VIM에서 PD 보다 ET집단이 더 적었다. 이러한 결과는 체감각 자극에 반응하는 시상 뉴론의 특성이 운동장애의 유형에 따라 서로 다르다는 것을 시사한다.

In order to introduce the touch to engineering and industries, it must be preceded to dstablish a quantitative barometer of the feeling. for this purpose, we developed a tactile measuring system to measure physical properties of texture, such as surface roughness, friction coefficient and compliance. The tactile measuring system uses a LASER type displacement sensor, which is a non-contacting system, in measuring the surface roughness. By considering that human tactile system is a contacting mechanism, this non-contacting method needs to be modified. As a precedent research of that, we compared the contacting and non-contacting method in this paper. Surface roughness of ten cloths were measured by using the measuring system, then compared to the test results using the Kawabata evaluation system(KES), which uses a contacting method in measuring the surface roughness.

The friction behavior of human skin is determined by the complex interplay of the material and surface properties of the skin, as well as the contacting material, and strongly depends on the contact parameters (e.g., pressure and sliding velocity) and the presence of substances such as water, sweat, or skin surface lipids at the interface. Including a study on the effect of a surface's physical roughness for skin sliding over the surface, various studies have been conducted to understand human tactile sensibility. However, to investigate products in relation to human tactile sensibility, more objective research is needed. This study performed sliding experiments between the skin and the surfaces of phone cases to understand how the texture, friction, and stick-slip characteristics are related. Eight phone case surfaces with different topologies and chemical (or mechanical) compatibilities with skin were prepared and tested multiple times.

This study is to inquire respective patterns of mental models caused by wrongful usages which can be experienced when a user who is used to a keypad-based mobile phone starts using a touch screen mobile phone and to find out the features of the user's logical process of correcting such wrongful usages to a new mental model. In addition, design improvement to be considered for easy generation of the mental model regarding touch screen mobile phones was reviewed in this study. We set up test subjects for the most frequently used seven high priority functions among touch screen phone functions and carried out the subject assessment together with interview surveys after the video observation experiment. Our test results show that test subjects who were used to keypad-based mobile phones tend to use operation knowledge related to the computer operational system(Window) or the web browse, navigation including Tap or Double Tap in order to correct the mental model when a wrongful usage is made. In addition, the result of comparison and analysis of the subject assessment and the video observation experiment data shows that wrongful usages of touch screen mobile phones mostly occurred in the field of 'information feedback' and 'navigation' among mobile phone components.

This study is to establish GUI (graphic user interface) in mobile touch phone for grooming user by using two dimensional emotion model determined by multi-dimensional scale method. The processes conducted in the research were as the followings: First of all, visceral, behavioral, and reflective factors of emotion (Norman, 2002) was defined from investigating the life styles of the Grooming users. Secondly, factor analysis was performed to extract the representative emotional words. In the third step, they were mapped into the two-dimensional emotion model through multi-dimensional scaling. Finally, the mapped emotional words were tried to be related to GUI factors of touch phones and normalizing their relation degree between 0 and 1. This study determined GUI factors significantly related to representative emotions described as special, self-centered, sophisticated, free, passionate, neat for application to mobile touch phone. This study determined the major emotion factors that should be considered the most important while designing the GUI factors.

The purpose of this research was to determine whether multimodal cues in an online shopping environment could enhance tactile consumer mental imagery, purchase intentions, and attitudes towards an apparel product. One limitation of online retail is that consumers are unable to physically touch the items. However, as tactile information plays an important role in consumer decisions especially for apparel products, this study investigated the effects of multimodal cues on overcoming the lack of tactile stimuli. In experiment 1, to explore the product, the participants were randomly assigned to four conditions; picture only, video without sound, video with corresponding sound, and video with discordant sound; after which tactile mental imagery vividness, ease of imagination, attitude, and purchase intentions were measured. It was found that the video with discordant sound had the lowest average scores of all dependent variables. A within-participants design was used in experiment 2, in which all participants explored the same product in the four conditions in a random order. They were told that they were visiting four different brands on a price comparison web site. After the same variables as in experiment 1, including the need for touch, were measured, the repeated measures ANCOVA results revealed that compared to the other conditions, the video with the corresponding sound significantly enhanced tactile mental imagery vividness, attitude, and purchase intentions. However, the discordant condition had significantly lower attitudes and purchase intentions. The dual mediation analysis also revealed that the multimodal cue conditions significantly predicted attitudes and purchase intentions by sequentially mediating the imagery vividness and ease of imagination. In sum, vivid tactile mental imagery triggered using audio-visual stimuli could have a positive effect on consumer decision making by making it easier to imagine a situation where consumers could touch and use the product.

The purpose of this research is to study the cause of obstruction in various knit pattern structures by understanding the needs of the customers, and to develop knitted fabric goods that satisfy the individual taste of consumers and that reflecting the latest fashions. Actual conditions of the manufacturer's designing processes must be examined. In addition, a comparison analysis of fashion sensibilities and preferences between producers and consumers had been made in order to study developing knit pattern structures. Questionnaires and interviews had been used as research methods. The research involved two groups: one group consisted of 57 producers, which included designers, programmers, and merchandisers working for a knit manufacturer in Seoul, while the other group consisted of 74 consumers, which included students with knitted fabric design as their major and those who have working knowledge of knitted fabrics. For a more accurate evaluation, 28 out of 150 patterns have been selected through a preliminary study conducted by 24 designers. On the 28 knit patterns, a sensibility evaluation had been made through the use of the sense of sight and sense of touch, which was followed by a frequency analysis, cluster analysis, and t-test using SPSS 12.0. The results are as follows: the fashion sensibility evaluation on knit patterns showed that structures, such as racking II or lace II, are typically elegant ('elegance'), while structures, such as links I or racking I, are typically 'active.' Furthermore, a 'country' image was displayed in structures such as cable I, cable II, and miss II. Links I appeared as 'sophisticated'. Miss I and milano were said to have 'modem' images. Lace II was regarded as 'ethnic', while racking II was said to have a 'romantic' image. 2:1 rib and milano were generally thought to be manly ('manish'). The fashion sensibility scale for each knit pattern has been made based on the above results. Based on producer and consumer responses, the sensibility evaluation on knit pattern structures showed that the two groups had similar preferences in knit pattern structures. Therefore, the fashion sensibility scale developed in this study can be used as a basic data for structure development when designing knitted fabric goods.
