Emoticons perform an important role as an enhancement to written communication, in areas such as Windows Live Messenger instant messaging, e-mails, mobile Short Message Services (SMS), and others. Emoticons are graphic images used in communications to indicate the feelings of people exchanging messages via mobile technology. In this research, the perceived usefulness of the emoticon in mobile phone text messages is verified with consumers using the five construct model of Huang. A K-means clustering technique for separating three groups based on levels of perceived usefulness of mobile emoticons is used with a structural equation model test using Smart PLS 2.0, and the bootstrap re-sampling procedure. We analyzed relationships among use of emoticons, enjoyment, interaction, information richness, and perceived usefulness. The results show there are relationships among use of emoticons, enjoyment, interaction, perceived usefulness, and information richness, however enjoyment of emoticons did not significantly affect the perceived usefulness of messages with emoticons alone. The results suggest emoticons have different affects on emotion in both mobile, and Messenger contexts. Our study did not consider more detailed media properties, and thus more studies are needed. Our research results contribute to mobile communication activation, provides companies with an understanding of key characteristics of consumers who use emoticons, and provides useful implications for improving management and marketing strategies.

This research aims to analyze the factors affecting the acceptance of social commerce, including performance expectancy, effort expectancy, social support, facilitating conditions, hedonic motivation, habitability, price saving orientation, and privacy concerns using the Unified Theory of Acceptance and Use of Technology (UTAUT2). UTAUT2 has been examined and modified in various contexts. The research model studies the acceptance and use of technology in the context of customers. This study adopts a quantitative method using the partial least squares regression (PLS) approach involving 244 respondents. The respondents are users of social commerce in Indonesia. The result of this research indicates that social influence, facilitating conditions, hedonic motivation, habit, price value orientation, and privacy concerns have a significant effect on behavioral intention. On the other hand, performance expectancy and effort expectancy does not affect behavioral intention. Furthermore, price value has a significant effect on social commerce user behavior. Lastly, facilitating conditions and habits does not affect social commerce user behavior. This research contributes to the development of theory by examining an additional variable, which is privacy concern. This study is significant since social media and social commerce have grown exponentially nowadays. Implications of the results for the development of the theory (UTAUT2) and practice are discussed in the article.

Consumer perception of the meaning of 'green' and 'green products' as well as how they use green claims (including terms, certifications, and marks) should be examined to help consumers pursue green behavior in everyday life. This study investigates what type of green claims prevail in the Korean consumer market and how consumers perceive the meaning of 'green' and green claims. For these purposes, media analysis, in-context research (shop visit) and a survey were conducted to collect green claims (including green terms and certified/noncertified green marks). Green claims in the consumer market were first summarized and analyzed; subsequently, the most frequently used 7 green marks and 15 green terms were selected to construct a consumer survey questionnaire on consumer perceptions of green claims. An online survey was performed via Embrain and the survey respondents consisted of 500 adult consumers over the age of 20. The field research results showed frequent green claims in the Korean consumer market. However, certified (and hence trustworthy green product information labels) were uncommon in the market. The only green claim widely known and used by consumers was the energy consumption efficiency label. Consumers were interested in the green information label not because it affected their utility cost nor because it was important for environment protection.

The purpose of this study is to figure out what the beauty of the modern body means and symbolizes from the aesthetic, sociocultural, and psychological perspectives and to investigate how it was formed in the modern Korean society. The data were obtained from the magazines and newspapers published from 1920 to 1939 and analyzed by qualitative content analysis. The results were as follows: First, the modern body from an aesthetic standpoint was characterized by the beauty of westernization, healthy body shape, sensuality, curvaceousness, activity, balance and harmony, and artificiality. The beauty of the modern body from a sociocultural perspective symbolized modern culture and implied the value evaluated by visual appearance. Therefore, the modern body became an object of consumption and the physical capital that gave women chances for their social success and happy marriages. The beauty of the modern body from a psychological viewpoint expressed individuality as a modern ego. Second, the formation of modern body esthetics was explained within the context of social comparison theory. The ideal body suggested by mass media was internalized as the aesthetic standard women used to create modern bodies and with which they compared their created bodies.

The phenomenon of electrical explosion of conductors is considered in the context of the changes in the energy and structural states of the metal at the stages of energy delivery and relaxation of the primary products of EEC. It is shown that these changes are related to the forced interaction of an intense energy flux with matter and to the subsequent spontaneous relaxation processes. The characteristics of nano-sized metal powders are also discussed. The preferential gas media during EEC is Ar+$H_2$. An increase in $e/e_s$ (in the range of values studied) leads to a reduction in the metal content. For reactive powders obtained with high metal content, it is necessary to separate the SFAP fractions, which settled on the negative electrode of the electric filter.

Based on the quincunx sub-sampling grid, the New Interleaved Hierarchical INTerpolation (NIHINT) method is recognized as a superior pyramid data structure for the lossless and progressive coding of natural images. In this paper, we propose a new image interpolation algorithm, Edge Adaptive Hierarchical INTerpolation (EAHINT), for a further reduction in the entropy of interpolation errors. We compute the local variance of the causal context to model the strength of a local edge around a target pixel and then apply three statistical decision rules to classify the local edge into a strong edge, a weak edge, or a medium edge. According to these local edge types, we apply an interpolation method to the target pixel using a one-directional interpolator for a strong edge, a multi-directional adaptive weighting interpolator for a medium edge, or a non-directional static weighting linear interpolator for a weak edge. Experimental results show that the proposed algorithm achieves a better compression bit rate than the NIHINT method for lossless image coding. It is shown that the compression bit rate is much better for images that are rich in directional edges and textures. Our algorithm also shows better rate-distortion performance and visual quality for progressive image transmission.

본 논문에서는 다양한 환경에서 사용자의 각기 다른 사용 상황을 인지하고 그에 맞는 콘텐츠 및 사용자 인터페이스를 실시간으로 구성하여 제공하는 방법에 대해 제안한다. 방송/통신 환경에서도 다양한 사용자가 다매체, 다채널 등 여러 방법으로 컨텐츠를 소비 하고 있기에 단말 환경 및 사용자 특성을 인지하여 그에 적응적인 콘텐츠와 사용자 인터페이스를 제공하는 사용자 반응형 서비스에 대한 논의가 계속 되고 있다. 또한 다양한 디바이스가 보편적으로 보급됨에 따라 사용자는 하나의 스크린에 모든 관심을 주는 것이 아니라 다양한 스크린으로 동시에 관심을 분산시킨다. 그 동안 사용자가 선호하는 콘텐츠가 제공될 경우 더욱 그 주목도를 높이기에 다양한 세컨 디바이스에 개인 적응적 사용자 인터페이스 및 컨텐츠를 제공하는 것이 서비스 차별화의 중요한 요소로 작용하고 있다. 제안하는 프레임워크는 다양한 세컨 디바이스 사용자가 IPTV 와 같은 VOD 서비스를 동시에 이용할 경우 개인화 디바이스를 통해 각자의 서로 다른 환경에 적응적인 부가 서비스를 제공 받는 서비스에 적용하여 테스트를 진행하였다.
