Purpose This study reviews technology acceptance research in the information system area and consumer behavior research in the marketing area, sets characteristics of convergence products, personality of consumers and communication channels as main concepts and demonstrates their effects on 'relative level of attraction' and 'intent to adoption. Design/methodology/approach The survey was conducted against potential consumers who have the intent to purchase electric communication media products that provides a variety of functions and service, such as a smart TV, a tablet PC and a smart watch. All items were adapted from previous literature and revised as appropriate the purpose of this study and measured on a 7-point Likert scale with answer choices ranging from "strongly disagree" (1) to (7) "strongly agree." Totally, 300 respondents participated in the survey. Out of the 276 respondents, incomplete or invalid 24 were discarded. With them, SPSS 18.0 and AMOS 20.0 for structural equation modeling were used for the analysis. Findings Main findings are as followed;- First, it is found that 'interrelationship of technology' and 'functional diversification' of convergence products has positive effects on relative level of attraction. Second, perceived behavior control has significant effects on the intent to adoption convergence products. Third, communication through mass media has positive effects on making potential consumers feel attraction about products while there is no relationship with the intent to a. On the other hands, it is demonstrated that there is no relationship influential relationship between communication through interpersonal channels and relative level of attraction while communication through interpersonal channels has significant effects on the intent to adoption.

We present an augmented reality (AR) application for cell phone where users put a virtual pet on their palms and play/interact with the pet by moving their hands and fingers naturally. The application is fundamentally based on hand/palm pose recognition and finger motion estimation, which is the main concern in this paper. We propose a fast and efficient hand/palm pose recognition method which uses natural features (e.g. direction, width, contour shape of hand region) extracted from a hand image with prior knowledge for hand shape or geometry (e.g. its approximated shape when a palm is open, length ratio between palm width and pal height). We also propose a natural interaction method which recognizes natural motion of fingers such as opening/closing palm based on fingertip tracking. Based on the proposed methods, we developed and tested the AR application on an ultra-mobile PC (UMPC).

Recent popularity of smart devices and social media seem to increase much interests on social learning, Despite of positive expectation on technology-based social learning, there are not many successful cases and practices of how to apply hands-on technologies and measure educational results. In this study, we tried to promote idea-sharing among learners in a classroom using web-based peer-review of assignments on a specific topic. Then we investigated effects of idea-sharing among learners in terms of individual knowledge construction. Experimental results show that idea-sharing promotes knowledge convergence and divergence, and then knowledge construction at learner's own.

Computer education is gradually focusing on a wide variety of areas of expertise such as production of visual media and software development, instead of on the use of ICT like before. Particularly, computer courses related to production of image media require a complex practice procedure and repeated practice, making the future hands-on work difficult. Therefore, this study tried to verify the effect of the change in running methods of the "computer graphic" course from offline to blended learning. This analyzed the students' lecture satisfaction survey results of before and after the change. As a result, blended learning was well received and led to the small variations in the scores of the satisfaction surveys between the lecturers. Additionally, many students responded that the blended learning was more effective in their satisfaction surveys.

This paper proposes the MAWUPC (Motion Adaptive Weighted Unmatched Pixel Count) algorithm to track multiple objects of similar color The MAWUPC algorithm has the new method that combines color and motion effectively. We apply the MAWUPC algorithm to face and hand tracking against complex background in an image sequence captured by using single camera. The MAWUPC algorithm is an improvement of previously proposed AWUPC (Adaptive weighted Unmatched Pixel Count) algorithm based on the concept of the Moving Color that combines effectively color and motion information. The proposed algorithm incorporates a color transform for enhancing a specific color, the UPC(Unmatched Pixel Count) operation for detecting motion, and the discrete Kalman filter for reflecting motion. The proposed algorithm has advantages in reducing the bad effect of occlusion among target objects and, at the same time, in rejecting static background objects that have a similar color to tracking objects's color. This paper shows the efficiency of the proposed MAWUPC algorithm by face and hands tracking experiments for several image sequences that have complex backgrounds, face-hand occlusion, and hands crossing.

Purpose : In an attempt to analyse gender-egalitarianism related to the general characteristics, sexual consciousness and behavior in middle school students, this study was carried out. This study will provide data that can be used to develop sexuality education programs on the basis of gender-egalitarianism. Method : The subjects were 141 students (70 boys and 71 girls) in 4 classes that were randomly selected from among 8 classes of first graders in a coeducational middle school, in Seoul. For the evaluation of gender-egalitarianism, a Gender Egalitarianism Scale modified by the researcher was used. Results : Major findings were as follows: 1. Gender-egalitarianism was significantly higher in girls compared with boys. All of the boys and girls, had high gender-egalitarianism in the aspect of woman's ability in groups without sexual discrimination, but low gender-egalitarianism in woman's sexual conversation and style of dress. 2. Gender-egalitarianism in boys who had experienced intersexual physical contact, categorized as holding hands, embracing, kissing, and petting, was significantly higher when compared with inexperienced boys. 3. Gender-egalitarianism significantly increased as the father's education level increased as well as the father's open-mindedness. Factors influencing gender-egalitarianism was social acceptance, the mass media, the attitudes of the school teachers, and the attitudes of older and younger student in school. Conclusions : Based on these results, boys' gender-egalitarianism was lower than that of girls. Systematic education on gender-egalitarianism, combined with sexuality education, is necessary for middle school students, especially boys. In the long term, social acceptable the, mass media, school and home life should be changed for the achievement of the equality of the sexes.

In an era where non-face-to-face meetings become common, eXtended Reality(XR) is rapidly developing and filling areas that are not satisfied in online meetings based on existing photos/video method. In particular, general users are also able to easily access and use HMD-type mixed reality devices. However, the basic operations applied in HMD-type in Mixed Reality(MR) with hands as the main input tool do not have a standardized system, and each manufacturer operates in a separate response to each other's hand movements. Therefore, this study considered that a systematic hand motion matching system considering the usability and efficiency of operations performed in mixed reality was necessary, and conducted a study to clarify this. First, the basic operation performed in the MR environment and its attributes were investigated, and at the same time, the structure of the hand and the attributes of the possible hand movements were identified. Based on the identified properties, it is intended to present a system that can intuitively and efficiently match basic operation properties in the MR environment with subtle operation properties according to the structure/context of the hand.
