    Abstract: Although according to the 2015 OECD survey South Korea ranks number one in broadband internet service in the world, the rural areas in South Korea still lack the enough internet infrastructure to access the national backbone network effectively. Because of the economic feasibility the internet service providers are reluctant to install the broadband internet for the rural areas where less than 50 households live. Recently South Korea has invested lots of efforts to provide broadband access to the rural areas to overcome the digital divide. In this research, to evaluate the performance of broadband internet service for rural areas in South Korea we develop the empirical model based on the information systems success model. Then, we collect the questionnaires from the subscribers who have used the broadband internet service since 2013. Finally, the structural equation model validates the causal relationship between system and/or service quality and performance. The major findings and suggestion for further research will be discussed in the conference in details.

    Abstract: Recent attempts to connect the current 'next billion' to the Internet in places such as sub-Saharan Africa have not met expectations. In places where Internet infrastructure has come online and prices have gone down, the expected consequent increase in uptake was not observed. I develop a framework that incorporates language in the the two-sided markets framework, viewing differences as transaction costs. As a result of the cross-side network effects, it is difficult to isolate the causal effect of one on the other. The exogenous introduction of the Setswana language interface on the South African Google Search website was a spillover of the development of that interface for the Botswanan Google website. This exogenous improvement in the accessibility of Setswana-language content has resulted in a substantial increase in the number of native Setswana speakers coming online and owning personal computers. This is turn has also led to increased usage of the Setswana language online. This adoption appears to also lead to improvements in employment.
    Keywords: Internet Access, language, two-sided markets

    Abstract: All people need to communicate with their families, friends, neighbours, and physicians through various communication means. However, there are common barriers to communication needs of mute or/and deaf people, most importantly in terms of the declining sensory and physical abilities. On the other hand, technological advances have led to the development of a variety of new tools and technologies through various communication medium including the Internet for assistive and augmentative communication for individuals with disabilities. Although communication through the Internet seems highly attractive, it poses privacy and security issues. In this paper a web-based secure message transfer application is proposed to address privacy related information security threats directed to software-based communication of mute and deaf people. The proposed application is practical and easy-to-implement, and is based on the integration of cryptology and steganography. With its easy-to-use graphical user interface suitable for different devices, it can easily be used by its potential users for ensuring the privacy and security of their message transfers. The main limitation of the proposed application is that the application requires a public web server and hence may be vulnerable against attacks directed to web servers if required precautions are not taken.
    Keywords: Security threats; message security; cryptology; steganography.

    Abstract: This paper examines the effects of information and communication technology (ICT) and offshoring on the skill demand in Japanese manufacturing. One of the contributions of this paper is that we focus explicitly on the demand for low-wage part-time workers, which we call low skilled workers. Estimating a system of variable factor demands for the period 1980--2011, we found that industries with higher ICT stock shifted demand from middle-low to middle-high and low skilled workers. Offshoring is associated with the increasing demand for high skilled workers but it has insignificant effects on the demand for middle-high, middle-low, and low skilled workers. The results together suggest that the increasing demand for low-wage part-time workers can be attributable to ICT in Japan.
