This study attempts to figure out the impact of Information and communication technologies (ICTs) on spatial structure and to speculate on spatial strategies in the electronic economy from a geographical perspective. The unprecedented development of ICTs based on the explosive use of the Internet was enough to lead to the expectation that physical distance would not be a significant barrier in business activities. In fact, however, at least at a current stage, the development of ICTs has not automatically removed the inequality in spatial structure. The accessibility to electronic space is different by economic and social status within a country as well as between countries. The importance of place, locality, and place-specific assets has been strengthened in the global economy. Physical proximity is still of great importance because it helps to minimize transaction costs, to exploit place-specific social networks, and to accumulate credibility for successful businesses. Likewise, the development of electronic commerce such as B2B and B2C EC also does not necessarily result in the ignorance of place and locality. Rather, the recognition of the importance of spatial strategies is extremely important for the success in online businesses. As a conclusion, the spatial dimension becomes more important in the digital era for successful businesses and balanced regional developments than ever before. The need for the improvement of ICT infrastructures, the development of human resources, and the establishment of regional innovation systems in peripheral areas cannot be overemphasized even in the digital era.

When new information communication technologies(ICTs) have appeared, researchers and praticitioners have explored how to spread the technologies. In e-commerce, social commerce has been introduced recently and attempts to understand social commerce have proposed diverse research models. This study proposed a hypothetical model which integrates technology readiness(TR), technology acceptance model(TAM), and theory of planned behavior(TPB). Through PLS path modeling, we found that every hypothesis except social norm-intention path alone proved significant. This result means that integrated model is useful to understand the adoption of new ICTs including social commerce. Finally, based on the findings, suggestions for future research were discussed.

Due to advances in information and communication technologies (ICTs) and the advent of the Smartphone, people have access to the internet and can work at any time and any where. These are however likely to cause negative effects such as the personal information leakage and invasion of privacy. Caused by negative aspects of ICTs, the stress is so-called technostress. Recently, it is reported that managers tend to task order to their subordinates using an SNS or mobile messenger on a real-time basis after office hours or even on holiday, leading to a sharp increase in technostress. While previous studies of stress indicate that it is associated with the counter-productive work behavior (CWB), no empirical evidence has shown about the relationship between technostress and CWB. This study aims to explore the effect of technostress on CWB. In addition, it seeks to clarify the moderating effect of leader-member exchange(LMX) in this relationship. Drawing on literature regarding technostress and CWB, hypotheses are developed and tested with the sample of 101 using regression analyses. Results show that technostress has a significantly positive effect on CWB, but LMX has an insignificant moderating effect in the relationship between technostress and CWB. Implications and limitations with suggestions for future studies are presented.

As measures for protecting users and ensuring security of electronic financial transactions, such as online banking, financial institutions in South Korea have implemented network segregation policies. However, a revision of such domain-centered standardized network segregation policies has been increasingly requested because of: 1) increased demand for remote work due to changes resulting from COVID-19 pandemic; and 2) the difficulty of applying new technologies of fintech companies based on information and communications technologies (ICTs) such as cloud services. Therefore, in this study, problems of the remote work environment arising from the network segregation policy currently applied to the financial sector in South Korea and those from the application of new ICTs such as fintech technology have been investigated. In addition, internal network protection policies of foreign financial sectors, such as those of the United States, United Kingdom, European Union, and Russia, and internal network protection policies of non-financial sectors, such as control systems, have been analyzed. As measures for the effective improvement of the current network segregation policy, we propose a policy change from domain-based to data-centric network segregation. Furthermore, to resolve threats of hacking at remote work, recently emerging as a global problem due to COVID-19 pandemic, a standard model for remote work system development applicable to financial companies and a reinforced terminal security model are presented, and an alternative control method applicable when network segregation is not applied is proposed.

This study focused on developing strategies of cyber-compact city, combining compact city with information and communications technologies(ICTs), in order to enhance sustainable transportation. The cyber-compact city development is defined as a development that is able to reduce travel by ICTs and encourage people to use transit or non-motorized vehicles such as bicycles for ICT-induced travel (especially, discretionary travel) by compact and mixed land use. It can be achieved with combining cyber and compact strategies with respect to network, node, and area. For example, ICT network may use transit network facility, a transfer station may be a hub of ICTs, and transit influenced zone may work with ICT service area. We proposed three cohesive strategies for the cyber-compact city based on literature review and case studies on cyber and compact cities. The first strategy is a cohesion between public transportation and telecommunication network by centering on the two for national and urban spatial linkage structure. That is, cities or urban centers and its peripheral areas can be connected by rail network, and extra space of railway network can be used for constructing telecommunication network infrastructure. The second strategy is a cohesion between public transportation node and telecommunication node by building up regional and urban telecommunication centers near to or at main railway stations. For this strategy, telework centers and communication service centers should be established mainly at transfer stations. The third strategy is a cohesion between public transportation impact zone and telecommunication impact zone as transit oriented development.

The trap levels of ZnO-based varistor are obtained by Isothermal Capacitance Transient Spectroscopy method. Here ICTS measuring system consists of YHP 4192A Impedance Analyzer and a personal computer for the data acquisition. Between $-40^{\circ}C$ and $60^{\circ}C$, the grain boundary trap levels of 0.48 and 0.94eV were detected for $ZnO-Bi_2O_3-MnO$ system. The hole omission spectra are observed in the case of the addition of CoO into the $ZnO-Bi_2O_3$ system, while the electron emission spectra are detected in the case of the addition of MnO. The nonlinear resistance coefficient $\alpha$ increases with the decrease of the dormer concentration. Finally, the trap level density of $ZnO-Bi_2O_3-MnO$ system is found to decrease with the amount of CoO, while $\alpha$ is found to increase with the amount of CoO.

Bicycle is one of the most important eco-friendly transport mode which can cope with global warming. ICTs(information and communication technologies) on bicycles became a dominant factor for success to the spread of bicycles to public as we experienced Public Bike System. In this paper, conceptualization and classification of u-Bike services are fulfilled and its priority was examined using AHP method. Group capabilities technique of ECII, a computer fool of AHP was invited to minimize bias on appraisal. 12 u-Bike services were conceptualized. U-service with highest adoptability was 'bike and ride' service which can link bicycle to public transportation. 'Prevention system from abandonment and theft' and 'public bike system' similar to Velib system in Paris are also considered to be very important services in u-City.

This study examines the relationships between the adoption intention and ill results/"digital divide" of informatization. It is very important to enhance the ability to use the information around the country today. Government invested large sums in informatization. As a result, we became a leading country in the information and communication technologies (ICTs). But the speedy growth in information society enlarges the gab between 'information haves'and 'information have-nots', which results in decreasing the efficiency of informatization. Now, we have to consider the idea of "information welfare policy" to approach the problems of "information poor"which refers to those deprived of opportunities to access ICTS and use of the Internet. This paper shows that we can not reach the information welfare society without the solution of these problems, and which are obstacles to progress in informatization. It is hoped that the results from this study bridge and close so called "Digital Divide" within society and create the impartial information welfare society.e impartial information welfare society.

In this paper, the reduction amount of CO2 due to the virtual international video-conference organized by ITU in order to reduce the greenhouse gas (GHG) is calculated. The comparison is made with the case of off-line conference. In the symposium organized by ITU, "The power of ICTs to save The planet", held on September 2009 the participants were highly encouraged to attend the symposium through video-conferencing for the reduction of GHG. As a result, 46 foreign participants and 16 among 170 domestic participants have attended at virtual video-conference, which resulted in about 94.7 ton of CO2 emission reduction. This international symposium firstly tried in conjunction with online and off-line has drawn a big attention in the aspect of global warming. Definitely such ITU's trial will make significant impacts on the holding of other international symposiums and forums.
