RFID(Radio Frequency Identification) technologies enjoy an enormous interest in all throughout the world, not only from the research but also from corporate practice. Although bar code is gradually substituted with RFID technology, the use of RFID technology in the companies is at the early stages and it's potential value isn't fully realized yet. RFID-related-trust is needed to solve these problems because these phenomena are related to uncertainties or risks disturbing RFID diffusion. This paper focuses on trust in the adoption of RFID and analyzes the effect to RFID technology acceptance of trust. This paper proposes 5 second constructs of trust; institutional trust, trust between companies, trust within company, technology trust, and service provider trust. In order to analyze some relationships between trust variable and 4 variables in TAM, structural equation modeling(SEM) is developed and SPSS 12.0 and AMOS 7.0 are used for analyses.

This paper empirically analyzes determinants of DTV (Digital Television) adoption in household survey data with IT-related household demand characteristics. To this purpose, we conducted a survey for the adoption of DTV to 1,000 households nationwide. In the questionnaire, various questions asking socio-economics characteristics such as age, education, income were included. Also, status of adoption and usage of IT services such as paid broadcasting, internet, and DVD were asked. To analyze the determinants of intention of purchasing, decision of purchasing, and the timing of purchasing DTV, we adopted the ordered logit, binary logit and multinomial legit models. When there is an order among groups, ordered logit was employed and when there is no orders among groups, multinomial logit was emplyed for the estimation. It is found that when conditions of other explanatory variable are constant, the more educated household heads are, the more probable they become early adopters of DTV. It is also found that other conditions being constant, the income level of households and IT-related household demand characteristics are very important factors affecting DTV adoption. Since the likelihood of purchasing DTV is much higher for those who know the government policy of analog broadcasting termination schedule than others who do not know, dissemination of the Korean government's digital broadcasting policy will affect significantly the adoption of DTV. And policy with various incentives ought to be employed to accelerate DTV adoption, because households with the older TV sets are more likely to purchase DTV. It is suggested that the Korean government should develop policy to connect both DBS (Direct Broadcast Satellite) and DTV since DBS subscribers are more likely to be an early adopter than non-subscribers.

Responding to the rapid delivery demands and variety of small-volume products through human resource-dependent logistics operations in online markets is difficult. Logistics robots in fulfillment centers are expected to increase due to difficulties in hiring workers and rising labor costs. Amazon operates more than 100,000 robots in its Fulfillment centers. Alibaba, DHL, and UPS are also introducing robot technology to improve the logistics efficiency. Logistics robots are being used actively in the fierce online market competition of the global distribution industry. On the other hand, Korea is relatively sluggish. To revitalize the introduction of logistics robots in Korea, it is necessary to examine the factors that influence acceptance. The description of acceptability was based on an expanded technology acceptance model that has been verified through various studies. Studies have shown that both the ease and usefulness of purchasing have significant effects, and that ease has the greatest effect. The more experience involved, the more innovative, the more positive. The usefulness was shown to be positive as the perceived risks are low, price efficiency is good, and social impact is greater. This study provides theoretical and practical implications for logistics robot development and marketing.

The purpose of this paper is to explain the recipient's psychology, which results from the operation of media, from the perspective of the fluctuation between immersion and contemplation. Media allow to perceive and speculate about specific objects or meanings. In addition, the media perform the function of expanding or changing the objects of perception and thought. McLuhan or Luhmann's media theory emphasized this function of changing the state of perception by inducing a contemplative attitude. This notion is exemplified by interpretation of the visual media history. In this paper, the cases of film and computer game are discussed. In particular, it is considered that VR media causing strong immersion have also developed in a way that allows recipients to contemplate an virtually constructed reality. The commercialization of Tilt Brush and the experimentation of VR painting artwork are the examples for this dual development.

The purpose of this study is to investigate what influence the external variables of the RFID system for eco-friendly agricultural products such as reliability, safety, effectiveness and innovation have on ease and usefulness, perceived value and behavioral intention. An empirical analysis were conducted to the general consumers over the age of 20 years who live in Seoul and Gyeonggi areas having experience of buying eco-friendly agricultural products in department stores, supermarkets and eco-friendly agricultural product specialty stores from November 10 to November 23, 2012, A total of 350 copies of questionnaire were distributed for this research and, excluding partial ones that were too concentrated on one side or found missing values, a total of 305 copies(87.1%) were used as the final statistical analysis data. The result shows that such external variables of the RFID system for eco-friendly agricultural products as liability, safety, effectiveness and innovation are useful enough as a theoretical basis for later study on RFID systems for eco-friendly agricultural products. Also, it reveals that, since all the process from production to sale of agricultural products can be seen, the products are provided safely for consumers, are objectively and rapidly investigated when problems occur, induce a positive attitude with their historical information, and are supplied through systematic management such as consumers' rights to know and choose and recall of unfit products.

The e-Book market has rapidly grown as an innovative product which is mixed its traditional and technological characteristics. However, decreasing user resistance to the e-Book is very important to continually keeping up its market growth. Previous studies for user resistance have been studied as a negative barrier for various innovative products with importance of user resistance. Nevertheless, the factors for user' resistance to the e-Book field have not been found out considering both perceived value and switching cost. Especially, both innovative technology and user specifics should be considered when explaining user resistance to adopting e-Books. Thus, the purpose of this study is to understand the process for user resistance to the e-book and find out its antecedents with perceived value and switching cost at the same time. As a result, it appeared that triability, uncertainty and complexity affected perceived value and switching cost. The user-based antecedents like social norm and perceived value increased the effect of self-efficacy. Also, self-efficacy and perceived value decreased user resistance whereas switching cost increase user resistance to the e-Book perspective.
