    Popularization of information communication technology has increased the importance of user-centered design approaches. For instance, user experience considerations propose to influence not only device's functions but also user's behaviors. The authors propose a conceptual model of use by applying the user-oriented and function-oriented models to generate relationships between user and functions depending on circumstances. This study examines the possibility of quantitatively understanding use by applying the conceptual model. For this purpose, we adopt user-experience evaluation references, which are derived from previous studies to quantitatively understand the use of a device. The text-mining method was used to analyze the description of web logs on the first-generation iPad, which is a representative product considering user experience. The results indicate that the use of an iPad could be inferred from the user-oriented model and the importance to stimulate lifelike behaviors that are free of operating and setting functions. The conclusion indicates the usefulness of this method to clarify the situation where activated the user behavior.

    Reforms in the broadcasting industry have recently been discussed and proposed, and deregulation and the revision of the Broadcasting Law have already been implemented in such a way that restructuring the market through establishing holding companies and M&A of broadcasting stations have already take place. However, these changes are insufficient for a thorough going reform of the private broadcasting industry. This paper based on rigorous theoretical analysis discusses possible reforms and provides fundamentals for the realignment toward more adequate systems. In so doing, this paper examines the efficiency of middle-sized so-called “main broadcasting stations” in the six major regions using DEA (Data Envelopment Analysis) and empirically identifies factors which determine efficiency by the Tobit model. Based on these empirical analyses, raising the in-house production ratio and the deregulation of the limitation for broadcasting services within one prefecture are required in order to fulfill requirements such as plurality, diversity and locality in the age of convergence.

    The digitization of terrestrial TV broadcasting is an important target in the New Zealand ICT strategy. The object of this paper is to demonstrate whether the digital switchover in New Zealand targeted for completion on December 1, 2013 will be implemented smoothly while referring to the precedent set in Japan. Although rural areas will be switched over prior to urban areas, this is in consideration of the delay in the proliferation of digital receivers in urban areas, and as a result, switchover is presumed to proceed smoothly. Since the time of the digital switchover in New Zealand is relatively late in comparison with other advanced countries, the price of digital television receivers is already sufficiently low and has reached a level that enables these devices to be easily purchased by residents, thereby serving as another factor indicating that digital switchover will be completed smoothly.

    Cable Television (CATV) is media that can provide telecommunications and broadcasting services. Since the 1990s, some prefectures supported the construction of CATV networks in their areas to bridge the digital-divide and to use as administrative intra-networks. In the 2000s, it became a problem to cope with digitalization of terrestrial TV broadcasting and to construct broadband networks especially in areas with disadvantages such as mountainous regions. To solve these problems, some other prefectures made support plans to construct CATV in those areas.This paper overviews cases to construct CATV networks in disadvantaged areas, and considers the purpose of CATV construction from the viewpoint of the ICT network and regional media.
