ISDN, the beginning of broadband and multimedia service, is a digital network that provides integrated end-to-end digital telecommunication services for transmissions of different kinds of information, from voice and facsimiles to data and images. In Japan, Britain and U. S there has been shown the demand of ISDN is considerable and ISDN technology is becoming quite stable. Furthermore,their ISDN service experience helps them to set up and carry out the marketing strategies for Internet access services such as ADSL, Cable Modem and WLL, etc. This paper examines and compares services, charge and discount scheme of ISDN across 14 telecommunication carriers. It can be utilize as a reference for diffusing ISDN as well as developing Internet access services and marketing strategies.

Open access movement supports the principle that the published output of scientific research should be available to everyone without charge. The term open access is used in the broad context of the wider movement. To achieve the objectives of open access to scholarly journal literature, BOAI(Budapest Open Access Initiative) recommends using two complementary strategies: 'self-archiving' in institutional/disciplinary repositories and 'open access journals.' This study introduces the strategies of open access movements and analyzes the ways to help the cause of open access by academic stakeholders(i.e., researchers, librarians, universities, publishers, foundations, learned societies, and government) from the perspective of two BOAI strategies.

This study analyzed the type, subject and open level of research data in the field of library and information science field shared by Figshare, and statistically analyzed the characteristics of data with relatively high recyclability. The results of the analysis showed that datasets and papers were most common data types, and open access and research data were the most common keywords of data, and that 70% of the data were published in a form that can not be processed mechanically such as pdf. As a result of analysis of the relationship between characteristics of research data and degree of sharing, open access areas such as APC (Article Processing Charge) were found to be most common in the subject. However in data type, gray literature such as paper found to be highly utilized rather than dataset.

The efficient and rational transmission rate system is one of the crucial factors in creation of fair and competitive electricity market. Transmission charge can be largely categorized into the line usage charge, system reliability maintenance charge, access charge and others. Therefore, transmission rate structure should be able to reflect these cost components reasonably. This Paper suggests an approach that could be used for the reasonable calcuation of transmission reliability costs with reflection of line sensitivity and line outage rate.

This paper proposes an advanced test circuit for detecting the connectivity between a drum ring of laser printer and PCB. The detection circuit of charge sharing is proposed, which minimizes the influences of internal parasitic capacitances. The test circuit is composed of precharge circuit, analog comparator, level shifter. Its functional operation is verified using $0.6{\mu}m$ 3.3V/40V CMOS process parameter by HSPICE. Access time is100ns. Layout of the drum contact test circuit is $465{\mu}m\;{\times}\;117{\mu}m$.

There is a considerable gap in the level of the Internet access charges among countries because of the history of the Internet use, current status of the Internet infrastructure, the Internet penetration rate, and so on. Low Internet access charge increases the number of the Internet users and the Internet penetration rate, which boosts economic activities. This paper empirically explores the impacts of the internet access charges on economic activities using a cross-country analysis based on data from 76 countries for the year 1998-2001. To this end, several versions of the neoclassical growth models, explicitly including the internet access charges, are estimated with the GDP used for a proxy for economic activities and the level of Internet access charges considered as an input to production. Subject to the appropriate caveats, the results show that the level of the Internet access charges make a significantly negative effect on economic activities. In other words, it is concluded that low Internet access charges of a county increase economic activities and the increased economic activities in turn raise the real income of the county.

In Korea, no institutional tool or regulation exists by which a retail business in charge of gathering and maintaining subscribers can be guaranteed independence from the wholesale business division of a fixed incumbent provider of essential facilities such as ducts, poles and copper or fiber cables, which may also be offering the same products to its rivals. For that reason, a wholesale division may have an incentive to intentionally disrupt the sharing of facilities requested by competitive operators in cooperation with the retail division. Ultimately, the facility sharing process will remain inactive when there is a lack of equivalent access to the fixed access network. Therefore, this paper analyzes recent cases of access network separation and suggests long-term measures for the successful implementation of the sharing of facilities.
