It is known that as many as 1 in 91 children are diagnosed with an autistic spectrum disorder, and the incidence rate of the autistic spectrum disorder is much higher than that of cancer in Korea. It is necessary to develop a novel technology to sense their emotional status and give proper psychological diagnosis and therapy, since the children with autistic spectrum disorder usually do not express their own emotional status. This article presents the state-of-the-arts on the affective computing technologies that include recognition of emotional status through bio-sensing and virtual affective agent modeling, and then proposes a novel system architecture for diagnosis and therapy of autistic spectrum disorder. The diagnosis and therapy system of autistic spectrum disorder is composed of bio-sensing module, virtual environment module with affective agents, and haptic interface module. The architecture proposed in this paper will enhance the objectivity to diagnose autism spectrum disorders, and enable continuous treatment in daily life.

In the aging society, the walking assist robot is a necessary device for being able to help the older and the lower limb disabled people to walk. In order to produce a convenient robot for the older and the lower limb disabled, it is needed for the research to detect the implicit walking intention and to control robot by a user`s intention. This study is a previous study to develop the detection model of the walking intention and analyze the user`s walking intention while a person is walking with Lofstrand crutches, by the combination of FSR and tilt signals. The FSR sensors attached user`s the palm and the soles of foot are sensing force/pressure signals from these areas and are used for detecting the walking intention and states. The tilt sensor acquires roll and pitch signal from area of vertebrae lumbales and reflects the pose of the upper limb. We can recognize the user`s walking intention such as `start walking`, `start of right or left foot forward`, and `stop walking` by the combination of FSR and tilt signals can recognize.

As occasion demands to obtain efficient information from many documents and reviews on the Internet in many kinds of fields, automatic classification of opinion or thought is required. These automatic classification is called sentiment classification, which can be divided into three steps, such as subjective expression classification to extract subjective sentences from documents, sentiment classification to classify whether the polarity of documents is positive or negative, and strength classification to classify whether the documents have weak polarity or strong polarity. The latest studies in Opinion Mining have used N-gram words, lexical phrase pattern, and syntactic phrase pattern, etc. They have not used single word as feature for classification. Especially, patterns have been used frequently as feature because they are more flexible than N-gram words and are also more deterministic than single word. Theses studies are mainly concerned with English, other studies using patterns for Korean are still at an early stage. Although Korean has a slight difference in the meaning between predicates by the change of endings, which is `Eomi` in Korean, of declinable words, the earlier studies about Korean opinion classification removed endings from predicates only to extract stems. Finally, this study introduces the earlier studies and methods using pattern for English, uses extracted sentimental patterns from Korean documents, and classifies polarities of these documents. In this paper, it also analyses the influence of the change of endings on performances of opinion classification.

Recently, UCC, which stands for User Created Content, has emerged in various media industries including Internet. However, there exists little research regarding interaction to overcome the drawback of UCC, one way superficial form. In particular, little research has been done on the creation and effect of experiential UCC type. In the existing research, the interactive feature shows to bring the effectiveness in the field of education or promotion. So, in this study, we examine the problem of provider-centered UCC and to solve this problem, we propose a new experiential UCC form with interactive functionality by adapting the product test between UCCs. From the results of the analysis on the effectiveness of UCC after users experience the proposed UCC related to water industry, watching the interactive UCC represented the values of the higher levels in the aspect of recognition change than watching the existing UCCs. Also, the outcome showed that if this interactive UCC invigorates, UCC application will be very useful in eduction, industry, and promotion. From the analysis of the question instrument on whether an interactive UCC would be helpful or not, the positive response ratios was 84% in promotion, 70% in education, and 52% in industry, respectively.

Recently, Study of functional clothing for Vital sensing is focused on reducing artifact by human motions, in order to enhance the electrocardiogram(ECG) sensing accuracy. In this study, considering the factors for each element found from the analysis, a 3-lead electrode inside textile embroidered with silver yarn was developed, and draft designs off our types of vital-signal sensing garments, which are `chest-belt typed` garment, `cross-typed` garment `x-typed` garment and `curved x-typed` garment, were prepared. The draft designs were implemented on a sleeveless male shirt made of an elastic material so that the garment and the electrodes can remain closely attached along the contour of the human body, and the acquired data was sent to the main computer over a wireless network. In order to evaluate the effects caused by body movements and the ECG-sensing capability for each type in static and dynamic states, displacements were measured from one and two dimensional perspectives. ECG measurement evaluation was also performed for Signal-to-noise ratio(SNR) analysis. Applying the experimental results, the draft garment designs were modified and complemented to produce two types of modular approaches `continuous-attached` and `insertion-detached` for the ECG-sensing smart clothing.

This study examined the influence of the SOA(stimulus onset asynchrony) between visual and auditory stimuli on the integration phenomenon of audio-visual senses. Within the stimulus integration phenomenon, the redundant target effect (the faster and more accurate response to the target stimulus when the target stimulus is presented with more than two modalities) and the visual dominance effect (the faster and more accurate response to a visual stimulus compared to an auditory stimulus) were examined as we composed a visual and auditory unimodal target condition and a multimodal target condition and then observed the response time and accuracy. Consequently, despite the change between visual and auditory stimuli SOA, there was no redundant target effect present. The auditory dominance effect appeared when the SOA between the two stimuli was over 100㎳. Theses results imply that the redundant target effect is continuously maintained even when the SOA between two modal stimuli is altered, and also suggests that the behavioral results of superior information processing can only be deducted when the time difference between the onset of the auditory stimuli and the visual stimuli is approximately over 100㎳.

This thesis analyzes the proportion and disproportion of faces through visual analysis and measured value for women faces in 20s and 60s. The proportion of bizygion breadth and face height is 1:1.34 in 20s and 1:1.39 in 60s which shows face height is ling in 60s, and 0.85:1:1 for upper face length, middle face length and lower face length in 20s which shows the proportion of upper face length and lower face length are long while they are 0.84:1:1.06 in 60s which shows lower face length is long and upper face length is short. If the proportion of the face is more than 2˚ which is severe imbalance, angle of eyes is 8% in 20s, 13% in 60s, and angle of nasal is 11% in 20s, 29% in 60s, angle of mouse is 11% in 20s and 40% in 60s, showing imbalance of 60s is severe. As above, It shows that face height is longer in 60s than in 20s and lower face is long among others because face`s change due to aging. Also, We able to know that face`s imbalance is severer in 60s than in 20s.

The development of new technology and diversity in user needs lead mobile phone manufacturers to establish new strategies different from the existing for user attraction. Product identity, and brand image are major strategies for differentiation and adding new values to a product. This research starts with stating emotional brand image as the brand image made by the actual usage and the emotion built from the experience while using the product. This research will compare emotional brand image of the three major mobile phone manufactures in Korea (Brand A, C, and S) using evaluation of six representative emotions from users while using the product. The result of evaluating actual mobile phone users and the emotion built while actually using the product showed the brand image, and especially the emotional side of Korean mobile phone manufacturers. The result of this research itself would not be sufficient to simply state the emotional brand image of Korean mobile phone manufactures, but with further research including age, profession, gender and other demographic factors the result of this research would surely be able to abstract a clearer view of emotional brand image of Korean mobile phone manufactures.

The knowledge base on emotional information is one of the key elements in the implementation of emotion retrieval systems for contents design of Mobile devices. This study proposed a new approach to the knowledge base implementation by automatically extracting color components from full-color images. In this study, the validity of the proposed method was empirically tested. Database was developed using 100 interior images as visual stimuli and a total of 48 subjects participated in the experiment. In order to test the reliability of the proposed `emotional information knowledge base`, firstly `recall ratio` that refers to frequencies of correct images from the retrieved images was derived. Secondly, correlation Analysis was performed to compare the ratings by the subjects to what the system calculated. Finally, the rating comparison was used to run a paired-sample t-test. The analysis demonstrated satisfactory recall ration of 62.1%. Also, a significant positive correlation (p<.01) was observed from all the emotion keywords. The paired Sample t-test found that all the emotion keywords except "casual" retrieved the images in the order from more relevant to less relevant images and the difference was statistically significant (t(9)=5.528, p<.05). Findings of this study support that the proposed `emotional information knowledge base` established only with color information automatically extracted from images can be effectively used for such visual stimuli search tasks as commercial interior images.

Product design is being recognized as an important source of sustainable competitive advantage. This research explores the effects of design evaluative elements on brand loyalty through design values. The results of this study are as follows. Firstly, most design evaluative elements have positive effects on design values. Aesthetic, unique, feminine, noble, and utilitarian elements of design evaluation influence three types of design values: rational, kinesthetic, and emotional. While unique design evaluative element does not have significant effects on rational and kinesthetic design values, it has significant affect on the emotional design value positively. Secondly, three types of design values have positive effects on attitudinal brand loyalty. In addition, emotional and kinesthetic design values have positive influences on behavioral brand loyalty. However, the emotional design value has an indirect effect on behavioral brand loyalty through attitudinal brand loyalty. Lastly, attitudinal brand loyalty has a significant influence on behavioral brand loyalty positively.
