In this paper, we propose a novel scheme for product effect analysis, termed PEM, to find out the effectiveness of products used for improving the current condition, such as health supplements and cosmetics, by utilizing online customer reviews. The proposed technique preprocesses online customer reviews to remove advertisements automatically, constructs the word dictionary composed of symptoms, effects, increases, and decreases, and measures products' effects from online customer reviews. Using Naver Shopping Review datasets collected through crawling, we evaluated the performance of PEM compared to those of two methods using traditional sentiment dictionary and an RNN model, respectively. Our experimental results shows that the proposed technique outperforms the other two methods. In addition, by applying the proposed technique to the online customer reviews of atopic dermatitis and acne, effective treatments for them were found appeared on online social media. The proposed product effect analysis technique presented in this paper can be applied to various products and social media because it can score the effect of products from reviews of various media including blogs.

This paper aims to study the using motivation and influencing factors of Chinese users' participation in live stream shopping through theoretical and empirical analysis, so as to evaluate the change in users' needs and improve marketing strategies. In doing so, I conducted a questionnaire survey for Chinese live stream shopping users and collected the required data. For empirical analysis, I used SPSS and AMOS software to carry out descriptive analysis, reliability and validity analysis and structural equation model analysis (SEM) to test the hypothesis. The results of the analysis showed that core competency and brand personality of the short video industry have a significant impact on user and customer perceived value, thus influencing users' using motivation. That is, users do not blindly follow live stream shopping but make their active choice. Therefore, it is suggested that live stream shopping platform should strengthen the e-commerce attributes and eradicate "the sense of false satisfaction", in order to achieve the effective communication of information. On the other hand, to stimulate the purchase motivation of users, the brand should build up its personality, and enhance user and customer perceived value in cyber marketing.

Even though the importance of reading voters' share of mind increases in political campaign, there is no research which analyzes engagement in perspective of political campaign. Therefore, the purpose of this research is to calculate political engagement index which is qualitative indicator about political campaign's immersion in candidate in perspective of engagement and provide scientific data for political advertisement and publicity strategy. For this purpose, A and B candidates who ran for 18th president in December 19th, 2012 are selected for subjects of the research. The young people whose voter participations are low in this presidential election are selected as subjects for responding questionnaire and are surveyed. This research is qualitative evaluation which tires to supplement a limit of qualitative analysis of content by surpassing quantitative evaluation including advertisement, promotion, public opinion on politics, ratings, etc. Evaluation attribute is designed to distribute 8 PEI into 0~100 score. If PEI is more than 50, then the score indicates immersion above average. If PEI is lower than 50, then the score indicates immersion below average. The model of the research will contribute to development of methodological research of political campaign strategy. Also, in the future, this model can be used as micro-targeting in each political campaign's election strategy.

This study aimed to investigate differences in the purchasing patterns of and the levels of satisfaction with cosmetic products, and the method of disposing dissatisfied cosmetics for female university students among China, Japan and Korea. Survey was conducted with 1,200 female coeducational university students in Beijing, Tokyo and Seoul and 1,115 were used for the data analysis. Data were analysed by frequency analysis, Cronbach's ${\alpha}$, chi-square analysis, analysis of variance, Duncan's Multiple Range test. The results showed significant differences in purchasing behaviors in China, Japan and Korea. Japanese students mainly got information through objective sources, while Koreans did so through human network. Regrading the evaluative criteria for basic care items, function and effect were the most important criteria for Chinese and Korean consumers and skin compatibility for Japanese. For color make-up, Chinese, Japanese and Korean respondents respectively cared the most on brand image, convenience of purchase and the current trend. Chinese tended to shop cosmetics at department stores due to store reputation, Japanese preferred supermarkets and pharmacies and Koreans shopped at discount stores for low price. The most influential human sources were friends and colleagues for Chinese and Korean, and models on advertisements and magazines for Japanese. Korean respondents displayed the highest level of satisfaction with cosmetics followed by Japanese and Chinese. As for the methods of disposing dissatisfactory cosmetics, Chinese were the most active in exchanging for other product; Japanese and Korean were not likely to use or throw the products away.

In this paper, we present a real-time hand pose recognition method to provide an intuitive user interface through hand poses or movements without a keyboard and a mouse. For this, the areas of right and left hands are segmented from the depth camera image, and noise removal is performed. Then, the rotation angle and the centroid point of each hand area are calculated. Subsequently, a circle is expanded at regular intervals from a centroid point of the hand to detect joint points and end points of the finger by obtaining the midway points of the hand boundary crossing. Lastly, the matching between the hand information calculated previously and the hand model of previous frame is performed, and the hand model is recognized to update the hand model for the next frame. This method enables users to predict the hidden fingers through the hand model information of the previous frame using temporal coherence in consecutive frames. As a result of the experiment on various hand poses with the hidden fingers using both hands, the accuracy showed over 95% and the performance indicated over 32 fps. The proposed method can be used as a contactless input interface in presentation, advertisement, education, and game applications.

If a digital signage system is operated in PC mounted in the Window OS then the implementing price is very high. For resolving this problem, we used the Smartphone mounted in ARM Cortex family of multi-core processor-based mobile platform. We developed a low-power low-cost digital signage system and a remote convergence content management program based on web server. This convergence system manages advertising content to a remote control device anywhere using remote control technology. This system is one integrated system with display and is a low-power consumed and is developed in very efficient hardware interface. And condition sensors(intensity of illumination, temperature, weather, GPS etc) is equipped in the developed system. Automatic contents builder and Context-aware SMIL module is also implemented in the convergence system. We achieved over 50% power savings comparing with conventional Window OS system and 16 points multi-touch in our system.

Web-based information services should be evaluated for accessibility and usability with various types of Internet Web-browsing devices, interacting with web information servers. A reliable ubiquitous Web information server, accessible and usable with a variety of Web-browsing devices (e.g. a full-browsing mobile phone), should be a unified center for personalized ubiquitous Web information services as well as for business models based on personalized advertisements. We studied an estimation of the accessibility and usability in Web interaction for personalized ubiquitous Web information services, as metrics for real-time estimation. We show empirical results based on implementation and experiments in Korea, Japan and China, using a test-bed Web site ('ktrip.net') and single-character Korean domain names (e.g. 김.net, 이.net, 박.net, 최.net, ㄱ.net, ㄴ.net ... ㅎ.net, ㅏ.net, ... ㅔ.net, ㄱ.com, ㄴ.com ... ㅎ.com).
