Objective: The aim of this study is to investigate and review the previous researches about objective measuring fatigue caused by visual stimuli. Also, we analyze possibility of alternative visual fatigue measurement methods using facial expression recognition and gesture recognition. Background: In most previous researches, visual fatigue is commonly measured by survey or interview based subjective method. However, the subjective evaluation methods can be affected by individual feeling's variation or other kinds of stimuli. To solve these problems, signal and image processing based visual fatigue measurement methods have been widely researched. Method: To analyze the signal and image processing based methods, we categorized previous works into three groups such as bio-signal, brainwave, and eye image based methods. Also, the possibility of adopting facial expression or gesture recognition to measure visual fatigue is analyzed. Results: Bio-signal and brainwave based methods have problems because they can be degraded by not only visual stimuli but also the other kinds of external stimuli caused by other sense organs. In eye image based methods, using only single feature such as blink frequency or pupil size also has problem because the single feature can be easily degraded by other kinds of emotions. Conclusion: Multi-modal measurement method is required by fusing several features which are extracted from the bio-signal and image. Also, alternative method using facial expression or gesture recognition can be considered. Application: The objective visual fatigue measurement method can be applied into the fields of quantitative and comparative measurement of visual fatigue of next generation display devices in terms of human factor.

According to the National Statistical Office and the Ministry of Health and Welfare Family Department, Korea has already estimated that the proportion of the elderly population aged 65 or over is estimated to be higher than the global average, and has already entered the "Aging Society". Moreover, it is estimated that the quality of life of the people improved by reaching the information society earlier than expected. However, unlike young people, elderly people show clear differences in access and use of information that is difficult to access new machines easily and cause intergenerational digital divide phenomenon. In order to solve such a phenomenon, we implemented a speech recognition based smart mirror system for elderly people. The installed system can provide lighting control, weather forecast and subway time information search service of the using voice recognition. Through the implemented system, it is expected that the elderly will have accessibility to new machines, information that gives a feeling of participating in the change of the new era will be obtained and the effect of living convenience will be expected.

The purpose of this study was to seek the means of enlarging the application of Saek-dong to fashion products by surveying and analysing the recognition and image of Saek-dong in college students. As a research procedure, the bibliographical survey on the meaning and history of Saek-dong was preceded in this study, and the students were examined on the recognition and image of Saek-dong through the questionnaires. The female students were more acquiesced with the Saek-dong and Saek-dong clothing than the male students. And the students thought that the Saek-dong was our original and traditional clothing because it was worn by our ancestors from the earliest years. The word Saek-dong reminded them of red, yellow, blue, green, white and red-brown colors in order of appearance. The most familiar color-arrange to them was red+yellow+dark-brown+green+blue, and the blue, purple, green, red, white color was thought as manly Saek-dong colors and the yellow, red, dark-brown, pink, white was regarded as feminine Saek-dong colors. Saek-dong was primarily associated with the image of Saek-dong clothing and most of the students expressed their feeling about the Saek-dong as 'cute.' Most of the students responded that the practical Hanbok was best illustrated as the most applied clothing of Saek-dong and that the attempt to apply the color and pattern of Saek-dong to other modern artistic products was likely to damage the worth of traditional Saek-dong. When it comes to the matter of applying the design of Saek-dong to the fashion products, male students thought that it could be best applied to the shirts, while female students thought that the design of Saek-dong could best be applied to the personal ornaments.

The purpose of this article is to prove the fun of cartoon has related in Reality. Ultimately, it will be occurred the expanding result in contact with reader's reality perception. I had pointed out this issue in introduction. Although Fun is our vital power, almost people recognize it as imagination result which is not related in Reality. As the result, we overlooked Fun is contacted in Reality recognition. Creation method of cartoon story emphasize "the Individual character" and "the original nature" also. As this result, it has limitation which neglect "Reality". In main subject, I explained the meaning of Fun and Reality in feeling Korea Cartoon. First, we looked around a theoretical background of fun. With take surveying for various fun characters in several category of cartoon. We can confirm that it was occurred the results contacting "Enlargement of actual recognition" commonly. Second, the main issue of Korea cartoon was "Reality" historically. But, described Reality in cartoon is different from true Reality. Therefore, cartoon is imagined Reality of writer. So he make a heros and make a fun putting a folk tail. Third, described Reality in Korea cartoons make a fun and reader's consensus which is from emotional reality. With limitation of writer's "Reality recognition", almost writers adapted to ideology of ruling classes. Forth, we surveyed Korean cartoons which described "true Reality". Newspaper cartoons during imperialism and Min-joong cartoon in 80' period and 2000th period life documentary cartoon, we participated three sector and surveyed each character. Especially, I am dealing with important inconsistency of true reality. As this result, My cartoon enlarge reader's true reality and make "Fun" of recognizing a true reality.

In this study, the relationships of factors influencing the ways alternative types of new digital products are accepted into the market will be structuralized. On the basis of previous research, it is assumed that customers intend to use alternative types of new digital products when they have a higher value than existing products. The consumer's feeling of attraction toward the product is another factor included in the evaluation of its quality. And the attraction of the products that the consumers feel is also included in the evaluation of the qualities of the product. The results of the study indicate first that a product's value affects its attraction, but not the usage intention of the customer. Second, the benefits of the product affect the customer's recognition of its value, while cost does not. Third, environment affects recognition by the customer of the product's attraction, while knowledge of the product does not. By structuralizing the factors that influence the customer's usage intention about alternative types of new digital devices, the causal relationships of the factors involved in the acceptance of new products into the market and their success can be comprehended.

This study sought to typify incontinence symptoms and how women over sixty perceive incontinence panties and pads. The study uses Q methodology to analyze the perception of these products by type. The research utilized Q methodology and the QUANL pc program for analysis. Type 1 was a type of depression and anxiety due to incontinence. Type 1 was a type of thinking that incontinence was hidden from others. Type 2 was a smell-sensitive reclusion. Type 2 was most concerned about smell, as people sometimes avoid interpersonal relationships because of urinary incontinence. Type 3 was function-oriented toilet frequently. Type 3 was recognizing that the absorption function of incontinence products is important, as the toilet is frequently used. Type 3 mainly wore underwear among incontinence products and thought that incontinence was not hidden from others.
