This study investigated perceived discomfort and reasons related to use three information technology products (personal computer, mobile phone and digital television remote controller), and extracted the universal design factors. 240 people (30 females and 30 males for four age groups) participated in the one-to-one interview type of questionnaire, and replied to degree of discomfort at level of items and the reasons of discomfort at level of detailed elements for each product. As a result, almost all age groups answered that using input buttons of mobile phone and remote controller and watching display of mobile phone caused discomfort. Binary logistic regression of the detailed elements showed that response rate of discomfort mostly increased with age, except for specific elements such as shape of mouse and remote controller, and location of function button of mobile phone. Some of the detailed elements had high response rate of discomfort from all age groups. The age groups also showed similar tendency for the elements to select one alternative for the reason of discomfort, but not for sound volume and size of mobile phone and button sensitivity of remote controller. Finally, the universal design factors were extracted for each product based on the results, and divided into common factors and factors classified by the age group. Through this study, we identified using practices of various age groups and their demands for the products. It is expected that extracted detailed elements can be considered as important design factors to design the products universally.

The purpose of this study is to present the basic approach of producing the luxury fashion brands containing of the Korean traditional traits on the basis of traditional transformation with the modern concept, taking the 'Vivienne Tam' 2000's collections. This study has focused on its transformation of the traditional one of China, and made this as the subject of investigation. It's design characteristic could be defined as "modern interpretations of China chic", and it would be divided into two groups. The ingenious mixture of Chinese tradition into the modern chic could be concluded like these. The external characteristics is categorized in the three ways (1) the aesthetic application of the Chinese traditional patterns(dragon, water waves, peony, Japanese apricot flower, bamboo, bats, Chinese characters etc.), (2)the modern application of Chinese traditional costume details(front opening of Chipao, mandarin collar and knot buttons) and (3)the modernization of Chinese traditional technique(knotting, embroidery, beading and paper cutting). To deal with the internal characteristics, (1)the aesthetic mixture of East and West, (2)the formative expressions of the traditional view on the universe and religion are remarkable. The Chinese embodiment and the view of the universe and religion was integrated into the patterns of dragon, water waves, clouds, fire, woods, and metals. In order to afford the creative designer capable of encompassing the East and West, the teaching about the Korean tradition along with the technical and practical aspect of fashion is most important, while encouraging the professional designer to make a sophisticated ones which are attributed to the Korean tradition, and thereby come to be attractive to the world customer. The study about the Korean costumes, traditional colors, the symbolic meaning of the traditional patterns, cuttings, compositions, extending to the various kinds of myths, songs, paintings and crafts are essential for the Korean designer brand to be the global luxury brands.

This study aims to analyze the design of current nurse uniforms, investigate the state of nurse uniforms, and uniform design preferences in order to ultimately develop functional nurse uniform, which satisfy their needs. First, observing photos of nurses' campaign on wearing a badge showed that opening of top uniform almost always incorporated buttons, and sleeves were mostly set-in half sleeves while collars tended to be mandarin collars. The colors were mostly white for both top and bottom, while the top showed a bit more variety in colors. White tops often incorporated hospital logos on them. Second, in terms of the nurse uniform distribution, each nurse is given one top and one bottom per year. In addition, either a cardigan or a jacket on top of the regular summer uniform constitutes the winter uniform, whereas the availability of cardigans differed by hospitals. Third, the main source of contamination of uniforms was blood, and the level of satisfaction was all low in terms of the design, function, and material of the uniform, calling for the enhancement and development of new uniforms. Design preferences were two-piece with pants, color preferences were blue and pink, and pattern preferences were hospital logo, stripes, and check patterns in the listed order of preference. Complaints were usually made on the contamination of front pocket of the top, lack of sufficient pockets for storage, and tightness of the sleeves. Some preferences on finishing were the princess seams, mandarin collar, set-in half sleeves, and button closing on top. The preferred belt was a mixed form of straight-lined belt and rubber belt, and straight lined hem and spandex blended fabrics were favored for the clothing.

This paper describes the smart illuminating system based on the obstacle environmental presetting to improve the user convenience to easy lighting and energy conservation. Obstacle environment has trouble controlling the illuminating equipment using manual buttons in certain circumstances, which requires a smart remote controller. The smart remote controller is operated by the smart phone, motion sensor and timer to turn on and off the lamps. The event sensor module transmits the signals of the event occurrence to equipment on the remote place when smart phone and motion sensor detect an event, and the illuminator received the event turn on or off the lamp. The system results in energy saving by simple on/off control and manipulating the operating time with controlling the illuminating system preset by user's obstacle or preference circumstances. The proposed system implementation is experimented to figure out the energy saving about13.5w/h and the optimized convenience control.

This article is designed to establish fundamental design criterion for theme park cast costumes in accordance with play type and space. There is an understanding that theme parks act as a play space that is designed to meet diverse playing desires. To analyze cast costumes, the theme park - 'Everland' in South Korea as an example, area was divided into attraction space and non-attraction space. Attraction space is mainly for full-scale play content areas and the non-attraction space is to enforce the attraction space experience. Roger Caillois's play theory states that there are 4 play types; Illinx, Mimicry, $Ag{\hat{o}}n$, and Alea. All 4 play types were shown through attraction and Mimicry at non-attraction. Each cast costume was analyzed in terms of apparel design elements - silhouette, textile, color, detail, and props - related to play type facility and cast role. Criteria for theme park cast costume designs were suggested based on the results. Illinx cast members who fulfill a safety-checking role wear high chroma warm color costumes with the accent on details in bodice cutting lines, collar edges, pockets, buttons and decorative ornaments. A complementary contrast is also used. The guidance cast in Illinx may wear a suit in bright/vivid color. Mimicry guidance cast costumes show meticulous perfection in imitation with the figure in its space. From head to toe, color, textile, and silhouette - every detail and even props should match the character. $Ag{\hat{o}}n$ cast costumes are strictly limited in detail and decorative ornament usage as well as in color, since they are in charge of the management and operation of a competition. Alea cast's role is a self-demonstrator. Alea cast members should be a real tarot card reader. However, a manual should control their costumes. A total of 10 cast roles at a non-attraction space should be designed to show job patterns clearly in accordance with the whole theme at the park.

With the increasing use of touch-enabled mobile devices such as smartphones and tablet PCs, the works are done on desktop computers and smartphones, and tablet PCs perform laptops. However, due to the nature of smart devices that require portability, QWERTY keyboard is densely arranged in a small screen. This is the cause of different typographical errors when using the mechanical QWERTY keyboard. Unlike the mechanical QWERTY keyboard, which has enough space for each button, QWERTY keyboard on the touch screen often has a small area assigned to each button, so that it is often the case that the surrounding buttons are input rather than the button the user intends to press. In this paper, we propose a method to automatically correct the input errors of the QWERTY keyboard in the touch screen environment by using the n-gram language model using the word unigram and the bigram probability.

Phase transformation phenomenon at high temperature was investigated by using designed TiAl-Nb alloys with addition of the ${\beta}$ stabilizer. Examination of dendritic morphologies in arc-melted button ingot could reveal the crystallography of the primary solidification phase. It was found that the addition of ${\beta}$ stabilizer(Nb) shifted the high temperature region of the binary Ti-Al phase diagram to the high Al composition side so that ${\beta}$ phase forms as a primary crystal even at higher Al composition compared with the binary Ti-Al system. The ${\beta}$ was found to be the primary solidification phase for alloys with Al content less than about 52 at.%. The composition of ${\beta}$ solidification in Ti-Al-Nb ternary system could be determined from the partial liquidus projection which was constructed by observing the microstructure of arc-melted buttons. The Ti-46Al-(6, 8)Nb composition was selected for ${\beta}$ solidification and the directional solidification was performed by a floating zone-type DS apparatus at the growth rate 30 mm/hr respectively.

In this paper, a dynamic warning system to forecast inland flooding associated with typhoons and storms is described. The system is used operationally during the typhoon season to anticipate the potential impact such as inland flooding on the coastal zone of interest. The system has been developed for the use of the public and emergency management officials. Simple typhoon models for quick prediction of wind fields are implemented in a user-friendly way by using a Graphical User Interface (GUI) of MATLAB. The main program for simulating tides, depth-averaged tidal currents, wind-driven surges and currents was also vectorized for the fast performance by MATLAB. By pushing buttons and clicking the typhoon paths, the user is able to obtain real-time water level fluctuation of specific points and the flooding zone. This system would guide local officials to make systematic use of threat information possible. However, the model results are sensitive to typhoon path, and it is yet difficult to provide accurate information to local emergency managers.

This paper presents a new modeling technique for the simulation of cloth specific characteristics with a set of hard constraints using an implicit constraint enforcement scheme. A conventional explicit Baumgarte constraint stabilization method has several defects. It requires users to pick problem-dependent coefficients to achieve fast convergence and has inherent stabilization limits. The proposed implicit constraint enforcement method is stable with large time steps, does not require problem dependent feed-back parameters, and guarantees the natural physics-based motion of an object. In addition, its computational complexity is the same as the explicit Baumgarte method. This paper describes a formulation of implicit constraint enforcement and provides a constraint error analysis. The modeling technique for complex components of cloth such as seams, buttons, sharp creases, wrinkles, and prevention of excessive elongation are explained. Combined with an adaptive constraint activation scheme, the results using the proposed method show the substantial enhancement of the realism of cloth simulations with a corresponding savings in computational cost.
