Recently, remote controls for home appliances have been produced as many as the number of home appliances per household, and new home appliances are being released, but the number of new remote controls is continuously increasing due to their separate functions. Therefore, it is not inconvenient for first time users to use many remote controls because it is difficult and bulky. In recent years, the practical use of a universal remote control, such as large companies such as SAMSUNG and LG are producing a variety of forms. In this paper, we explain how to transmit and receive data format and infrared remote control through custom code identification method used in IR remote control for each company, and to see the size, characteristics and difference with ordinary remote control through ATmega128 remote control experiment. The ATmega128 can be used to control various home appliances displayed on the LCD. As a result, it can be seen that the number of remote controllers having only each function is reduced, and the integrated remote controller using ATmega128 Can handle household appliances.

In the context of integration of culture and tourism, the effective application of folk art in cultural creative products is of great significance to the development of local cultural industry. Xuzhou paper-cutting is the only world-class intangible cultural heritage project in the northern Jiangsu region of China. Its high humanistic value and artistic characteristics are widely used in modern art design. The application of cultural and creative products relative to paper-cutting in Xuzhou mainly focuses on two-dimensional decorative and ornamental products, which is short of diversity in form and not practical. In addition, it doesn't meet the aesthetic needs of living of modern people, This article studies paper-cut works by Wang Guiying and proposes principles for the design of cultural and creative products relative to paper-cutting by analyzing the typical "goose" pattern in Wang's paper cutting handcrafts. By exploring the application value of Xuzhou paper-cutting in cultural and creative product design and demonstrating the feasibility of the design principles via visiting experts, this article hopes to provide some reference for the modern inheritance and innovative development of paper-cutting culture.

The purpose of this study was to find differences in evaluation criteria and to find differences in preferred images based on benefits segmented groups of jeans products consumers. Male and female Korean university students participated in the study. Quota sampling method was used to collect the data based on gender and a residential area of the respondents. Data from 492 questionnaires were used in the analysis. Factor analysis, Cronbach's alpha coefficient, cluster analysis, one-way ANOVA, and post-hoc test were conducted. As a result, respondents who seek multi-benefits considered aesthetic criteria(e.g., color, style, design, fit) and quality performance criteria(e.g., durability, ease of care, contractibility, flexibility) more importantly when evaluating and purchasing jeans products. Respondents who seek brand name considered extrinsic criteria(e.g., brand reputation, status symbol, country of origin, fashionability) more importantly than respondents who seek economic efciency. Respondents who seek multi-benefits such as attractiveness, fashion, individuality, and utility tend to prefer all the images: individual image, active image, sexual image, sophisticated image, and simple image when wearing jeans products. Respondents who seek fashion are likely to prefer individual image, and respondents who seek brand name more prefer both individual image and polished image. Mean while, respondents who seek economical efficiency less prefer sexual image and polished image.

Mobile phone-related industries have been mainly concentrated on attracting the new customers and increasing the market share such as for the aggressive marketing activities, but it is the time to find an effective strategy to preserve existing customers since the mobile phone market had already reached the saturation. In this study, the properties of mobile phone that influence on the choice of handset and telecom company were analyzed. General properties of respondents were explored and the mobile phone properties were grouped by common factors. And analyzed the effect of factors on customer satisfaction with structural equation model. 10.4% of respondents are used their handset more than two years and 48.7% wanted to purchase other manufacturer's handset if they repurchase mobile phone. These results might come form the fact that the life cycle of mobile phone become shorter by the heating competition in mobile phone market and, to some degree, the influence of smart phone which recently become globally popular. Four factors, 'Hardware Quality', 'Practicality', 'Convergence Functions' and 'Level of Awareness', are induced from the mobile phone properties. In Structural Equation Model analysis, 'Hardware Quality' and 'Practicality' have significant and positive effects on Customer Satisfaction.

This study focuses on an effectiveness of socially recommended advertising on social network sites (SNSs) and investigates the impact of three critical factors on SNS advertising effectiveness - reward type for advertising recommenders' intention, product type on advertisements, and tie strength. A $2{\times}2$ factorial design was used to test the interaction effects between the two variables, reward type and product type on advertisements, moderated by tie strength. The results indicate that when participants observe socially recommended advertising, hedonic product ads with non-monetary reward shows the most effectiveness, and reward type and product type are also effective. In the combination of reward type and product type, we have confirmed the regulating factor influencing the effectiveness of social advertising according to the tie strength between the recommenders and the consumers. Strong-tie recommenders have more influence on the effectiveness of the social advertising than weak-tie recommenders. Based on these results, theoretical and practical implications were provided to refine marketing environments on SNSs.

The purpose of the paper is to examine sidedness effects of comparative advertising and moderating roles of the emotions of customer and product type. To test the research hypotheses, this study conducted experimental designs. One hundred ninety-two undergraduate students were assigned to one of the four experimental groups. Comparative Advertising message type and product type were manipulated as between-subject factors. There was a surprising event situation(free gift event) when participants came to laboratory for experiment, which is for the emotion manipulation. If a participant in a positive emotion group, he or she gets a free gift. The data demonstrate that comparative message type have a significant effect on both attitude toward the advertising and acceptance intention. In addition, consumers' emotion and product type play a significant moderating role between the message types and the dependent variables. The results of this study contribute to the literature as a new attempt to examine the sidedness effect of the comparative advertising message. We suggested that message types and consumer's emotion is one of very important aspects for a comparative advertising and marketers should consider people's emotion when they release a comparative advertising, which can help when marketers make their strategy for a comparative advertising.
