터치패널은 키보드나 마우스와 같은 입력장치를 사용하지 않고, 스크린에 손가락, 펜 등을 접촉하여 입력하는 방식이다. 누구나 쉽게 입력할 수 있는 장점으로 인해 기존에는 현금인출기, 키오스크 등 공공분야에 주로 많이 사용되어 왔으나, 최근의 터치스크린은 휴대폰, 게임기, 네비게이션, 노트북 모니터 등 개인정보기기의 입력장치로 활용분야가 넓어져가고 있다. 기존 터치패널은 유리 기판 위에 ITO박막(투명전도막)을 진공코팅하여 사용하여 왔지만, 최근 터치패널은 경량화를 고려하여 PET 필름 기판 위에 ITO 박막을 진공코팅하여 사용하고 있다. PET 필름의 유연성 때문에 ITO 코팅된 필름을 PC 혹은 강화유리 위에 OCA 물질을 이용하여 다시 고정하여야 한다. 이때 터치패널 제작시 생산공정이 늘어나 생산성이 떨어지고, 터치패녈의 광투과율도 떨어지는 2차적인 문제가 발생한다. 이를 해결코자하는 터치페널 업체의 Needs가 있고, 최근에 이를 해결하기 위하여 강화유리와 플라스틱 기판 위에 ITO 박막을 직접 진공코팅 하는 공정개발이 진행되고 있다. ITO 박막은 진공코팅 중에 열을 가하여 결정화를 이루어야 하는데, 강화유리와 플라스틱은 기판의 열에 약한 특성을 고려하여, 열을 가하지 않고 ITO 박막을 진공 코팅하여야 한다. 이러한 ITO 박막의 진공코팅 공정에는 In-line magnetron sputtering system이 사용된다. 본 연구에서는 In-line magnetron sputtering system을 사용하여 강화유리와 플라스틱 기판 위에 정전용량방식 터치패널용 패턴 인비저블 ITO 투명전도막을 제작하고 그 특성을 조사하였다. ITO 박막의 면저항은 150 Ohm/cm2, 최고 광투과율은 90.56% (@583), 그리고 550 nm에서 광투과율은 90.46%로 ITO 박막 코팅 전후에 투과율 차이가 0.4임을 확인하였다. 정전용량방식의 터치패널에서는 ITO 박막 코팅 전후에 투과율 차이가 1이하의 특성, 즉 패턴 인비저블의 특성을 필요로 하는데, 이는 ITO 박막 패턴후에 패턴이 보이지 않게 하기 위해서이며, 이러한 시장의 Needs를 고려하면 본 연구에서 매우 중요한 연구 성과를 얻었다고 말할 수 있다. 그리고 강화유리와 플라스틱 기판 위에 여러 종류의 ITO 투명전도막을 제작하고, 또한 감성터치에 적용되는 ITO 투명전도막을 제작하여, 그 특성을 조사하여 이를 논하고자한다.

Nowadays, in the so-called 'smart era', people are likely to feel more comfortable in on-line meetings than in off-line meetings. However, on-line meetings are often considered unimportant and it is difficult for participants to share their feelings. This paper suggests a mobile application that can revitalize off-line meetings to address these problems. Wecok Application, which suggests the best meeting place by applying users' preferences and their locations, provides a function-oriented user interface and simple touch flow. Wecok consists of a client/server software, and currently supports only three users simultaneously. It enables exchange of off-line and on-line communication by expanding meetings from on-line to off-line. By using Wecok, users can easily decide on an off-line meeting place.

Network externality can be defined as the effect that one user of a good or service has on the value of that product to other people. When a network externality is present, the value of a product or service is dependent on the number of others using it. There exist asymmetries in network externalities between the online and traditional offline marketing channels. Technological capabilities such as interactivity and real-time communications enable the creation of virtual communities. These user communities generate significant direct as well as indirect network externalities by creating added value through user ratings, reviews and feedback, which contributes to eliminate consumers' concern for buying products without the experience of 'touch and feel'. The offline channel offers much less scope for such community building, and consequently, almost no possibility for the creation of network externality. In this study, we analyze the effect of network externality on the competition between online and conventional offline marketing channels using game theory. To do this, we first set up a two-period game model to represent the competition between online and offline marketing channels under network externalities. Numerical analysis of the Nash equilibrium solutions of the game showed that the pricing strategies of online and offline channels heavily depend not only on the strength of network externality but on the relative efficiency of online channel. When the relative efficiency of online channel is high, the online channel can greatly benefit by the network externality. On the other hand, if the relative efficiency of online channel is low, the online channel may not benefit at all by the network externality.

Motion sickness or dizziness caused by visual and other sensory inconsistencies In virtual reality content seems to be a major problem. To solve the problem, research has been actively underway to satisfy the five senses. Among them, the most researches on the touch are many studies on hardness and texture, but the studies on temperature seem relatively small. Therefore, in this paper, we present a calculation model that can sense the temperature derived from the principle of heat energy moving from high temperature to low temperature, not the temperature of the material. Because heat energy is determined by the heat conductivity, temperature, and area of contact, which are the inherent characteristics of a material, the degree of heat felt by a person depends on the type of material, the temperature of the material and the area of contact with the object. The thermal energy shift per unit time of the material was calculated using the thermal conductivity law and the specific heat formula, and the thermal energy reproduction method that changes per unit time of the material was studied using the thermoelectric element.

This study details the actual wearing conditions and favored design of ready-made pants for obese women, particularly for those in their twenties and thirties. The actual problems that customers feel and the preferred design of pants were suggested based on the survey and from the standpoint of consumers. The findings of the survey are as follows. The actual wearing conditions in the survey, 80.5% like wearing pants. The main reason to prefer pants is that pants are more convenient for social or professional work activities. The main reason to avoid wearing pants is that the pants (in general) do not mask an obese body shape. The most favored was Denim/Elastic and the second most favored was Cotton/Elastic from the survey. On average, elastic materials are preferred over non-elastic materials. The reason was the comfort in wearing and convenience in social or professional activities that could mask obesity. In terms of the style, the most favored was blue jeans and the second favored was semi-formal. A straight-silhouette is the most favored as it was able to help mask obesity. The most favored position for the waistline is 4 cm lower than the natural waistline. The most favored pant length is where the pants slightly touch the floor when they stand with shoes on. For obese women the pants development that covers the weak points of the body shape giving, which is comfortable and active are desired.

Quick Response based Mass-Customization can be produced and distributed customized goods and services on mass basis in apparel e-business. Because consumers cannot touch and feel the apparel products in e-business, they tend to have the negative buying behavior. The purposes of this study were to analyze factors of texture image, and to investigate the differences of consumer sensibility on texture image of apparel products based on different marketing channels (on-line/off-line). Two types of questionnaires for on-line and off-line were used to assess consumer sensibility on apparel fabric. The 8 swatches were selected based on the previous literatures. 202 returned questionnaires for each type (on-line/off-line) were analyzed by t-test, mean and standard deviation with SPSS 10.0. The result of this study was showed that there were partially significant differences on consumer sensibility on texture image of apparel products between on-line and off-line. In case of corduroy, consumers perceived more high-class image under on-line than off-line. In case of taffeta, consumers perceived more thin and dense image under off-line (traditional marketing channel) than on-line (e-commerce). In case of denim, consumers perceived more thin and natural image under off-line than online. In case of organza, consumers perceived more natural image under on-line than off-line. In case of satin, consumers perceived more natural image under on-line than off-line. In case of chiffon, consumers perceived denser image under on-line than off-line. In case of velvet, consumers perceived thinner image, higher-class image, and more natural image of texture sensibility under on-line than off-line. In case of single jersey, consumers perceived higher-class image, and denser image of texture under on-line than off-line.

Many festivals are based on overseas municipalities 'city image marketing' planning. This trend is gradually reflected in this country as with the Kimcheon International Family Theatre Festival in the Republic of Korea. Gimcheon promotes itself as the central city of happiness 'city image marketing'. Most of these dimensions are in the middle of planning a festival when the Manjiman Kimcheon International Family Theatre Festival Theatre Festival, and the differentiation of the other audiences that drive successful practices in terms of box office need to be determined. This paper presents the history and status of the Kimcheon International Family Theatre Festival Theatre Festival and others based on the reports point out the distinction of a 100% share of the audience for the fifth consecutive year to analyze the cause. In particular, with local art and local performing arts festivals, audiences through a combination of 'show' Theatre Festival are also indirectly involved in the 'touch and feel' willingness to participate. In the Kimcheon International Family Theatre Festival there are significant challenges for improvements in significance.
