The telecommunications industry pro-grossed as old media, but new media is going into a new era of multi-media in the 21st century. In the latter half of 1970s we saw a boom of new media as a post-telephone era began. As the machines grew to the world level(standard), facsimiles, minitels of France and word processors of Japan were developed. Today some 15 years since the advent of new media era, the progress of technology is astonishing. Advancement of technology is seen in V and U letters attached to semiconductor chips, astonishing capability advancement of light emitting lasers and photo-diodes, etc and additionally technology advancement in large capacitized light disks. Thus these technologies have made possible transmitting a broad band network and a mobile communication and digitalized broadcasting. Increased capacity of every terminal, e.g, "letters $.$ voice $.$ still and mov-ing pictures" are essential for new media simultaneous and two -way transmission.

The present research investigates the factors influencing the elderly adults' life satisfaction in the era of information and communication technology (ICT). Specifically, we examine whether the elderly individuals' digital literacy skills (i.e., ability to use PCs, ability to use mobile devices, and ability to distinguish information) and perceptions (i.e., perceived usefulness of digital technology, self-efficacy in using digital devices, and social interaction) predict their life satisfaction. To answer the research question, we performed a hierarchical multiple regression analysis using the elderly Korean adults aged 55 or older. The results indicate that (1) females (vs. males) are more satisfied with their life; (2) the higher individuals' age, education and monthly household income, the higher their life satisfaction; and (3) their perceived usefulness of digital technology, self-efficacy in using digital devices, social interaction, and ability to distinguish information are positively associated with life satisfaction. The findings provide important implications to enhance life satisfaction of the elderly adults in the ICT era.

This study analyzes factors that determine the usage of digital information by senior consumers in the mobile environment. Senior consumers are alienated from digital information in South Korea; therefore, there have been increasing attempts to resolve this digital divide and reduce the digital information usage gap between young adults and senior consumers. The study used panel data from the National Information Society Agency (2017); there were 1,463 participants, aged 50-79 years. SPSS 19.0 was used to conduct the statistical analyses for frequency, factor analysis, Cronbach' ${\alpha}$ analysis, descriptive analysis and hierarchical multiple-regression analysis. The results are as follows. First, negative attitude toward information society negatively influenced the mobile digital information usage in diversity context. Second, average monthly income, degree of digital device usage motivation, positive attitude toward digital device usage, digital literacy of PC & Mobile, and family support positively influenced the mobile digital information usage in diversity context. Third, negative attitudes toward information society negatively influenced the mobile digital information usage in quality context. Forth, average monthly income, degree of digital device usage motivation, positive attitude toward digital device usage, digital literacy of PC & mobile, and family support positively influenced the mobile digital information usage in quality context. The study results can help further understand mobile usage behaviors among senior citizens and the implications on their quality of life in the digital information era.

With the advent of the Internet era, consumer lifestyles have been changed tremendously, and mobile payment has carried out an increasingly extensive coverage of the people's life trajectory. Taking the design of the mobile payment interface as an example, we use a conjoint analysis method to survey college students in Guangxi, where questionnaires are collected from 270 people in different groups according to gender. The method separates the attributes that affect consumer choice of mobile payment interface design and the utility value of the attribute level to analyze consumer needs and preferences, and then obtains consumers' potential evaluation criteria for mobile payment interface design. The results of the study show that the attributes that influence consumers' choice of mobile payment interface design are, in order of preference: page layout, identification convenience, verification, module distribution, entertainment, and information encryption. Consumer groups of different genders show differences in their preferences in the mobile payment interface design and Consumer needs reflect consumer psychology. Several findings are obtained on the consumers' preferences on the mobile payment interface design, which may be used to improve future design processes.

As the research activities related to 'Ubiquitous Computing' whose concept was introduced by Mark Weiser are growing, RFID(Radio Frequency Identification) technology has recently gained attention as a technology to advance the ubiquitous computing and a lot of related researches are also in progress. Research works done so far are mainly linked to the situation that the research outputs apply to meet the requirements for asset tracking and data sharing with partners over supply chain by using fixed RFID readers. However, it is essential that users have access to real-time information about the tagged objects and services whenever and wherever they want in the era of ubiquitous computing, so mobile devices-including PDA, smart phone, cellular phone, etc - which are equipped with an RFID reader can be regarded as an essential terminal for users living in ubiquitous computing environment. As far as the application with mobile devices are concerned, there are many considerations due to their limited capabilities of data processing, battery consumption and so on. In this paper, we review the generic RFID network model and introduce the revised RFID network model in consideration of incorporation with mobile devices equipped with an RFID reader. Also, we derive the requirements for software embedded within an RFID- enabled mobile terminal and then discuss essential components for implementation. Moreover, we develop the applications for asset management at museum by using mobile RFID network model.
