Government and public institutions have been releasing a number of mobile applications in order to provide diverse public services in the mobile environment. However, due to their one-sided and fragmented service with the lack of adequate care for users, the utilization rate is extremely poor. Therefore, this study, based on a relevant literature review, identified and derived the five key factors (usefulness, convenience, interactivity, information credibility, and social pressure) for users' mobile service adoption. Then, through in-depth interviews with five users and five experts regarding the 'business support app' of one public agency (H institution) that specializes in SMEs, we found that all of these factors are important for users' mobile service adoption. Users' satisfaction could be significantly improved through real-time response to their needs. In addition, providing them with useful and tailored information can lead to mutual trust between public institutions and users. Consequently, as these user-oriented services can increase users' loyalty and boost the utilization rate of the public apps, public institutions should always put persistent efforts to cope with users' demands.

As global climate changes, the interest in environmental crisis is increasing and a number of international agreements and regulations against this crisis are being established. Global information technology(IT) corporations are building their own pro-environmental green IT strategies to cope with the regulatory measures. Green IT broadly refers to pro-environmental technologies designed to replace hazardous materials, maximize energy effectivity, and find alternative energies. In the current stage of the IT industry development, Green IT specifically refers to the technologies that deal with the server heat generation and the energy reduction in data center. This study defines the concept of Green IT and reviews its origin and necessity. Then, it examines the issues regarding Green IT industry in Korea as well as other countries and compares the Green IT strategies developed in each country. Reviewing the recent development of IT and data center market enables us to see that overall Green IT strategies focus on the establishment of Green Internet Data Centers. Therefore, this study analyzes the cases in which some domestic and foreign corporations introduced Green Data Centers in order to examine the protocol and legal requirements for building Green IT, the aspects of environmental evaluation and design, and specific strategies for launching Green IT strategies and its future assignments. The conclusions of this study are as follows. First, to introduce Green Data Center as a strategy to build Green IT, the government and corporations should cooperate with each other. Partial introduction at the initial stage is desirable because, through the process, mutual trust between the two parties can be built more smoothly. Second, CEO's determination to build Green IT and continue its operation is indispensable. CEO's are required to have clear understanding as to why Green IT needs to be built and how it should be constructed. Those who initiate the construction of Green Data Center for Green IT need to know the definition and necessity of Green IT while at the same time understanding the implicit meanings of Green IT. They also need to be aware of future-oriented values of Green Data Center and readjust their corporate business activities in the pro-environmental direction. Finally, not only the CEOs' pro-environmental activities but also the change of mind on the part of all corporate employees is required to realize Green IT. It should be remembered that pro-environmental Green IT starts with minor activities.

Today, labor unions have become more serious and have more critical roles in the IT industry. Labor union should enhance the quality of working life in an organization. It is the most important role of the union to satisfy employees. When a labor union enriches its roles, members have a positive attitude to the union. Hence, workers will be more satisfied and make more positive results. Moreover, although members have positive attitudes to the union, when labor and capital have a negative relationship, workers do not make the best performance. Furthermore, although unions and the companies work in close cooperation, when members have a negative attitude to the labor union, workers' performance will also decline. Hence, a positive attitude to labor unions and union-management relations has a mutual benefit for performance. This study explains these relationships with the effect of attitudes to labor unions (satisfaction, trust, and commitment) on organizational commitment and organizational citizenship behavior, and the moderate effect of union- management cooperation. The purpose of this study is to suggest that labor unions should have a positive relationship with management and win members' recognition in the IT field.

It is easy to install and maintain a mobile multi-hop wireless network due to its self-organizing characteristics. However it has security weakness of the authentication of mobile multi-hop relay stations. Specially, the mobile multi-hop relay network in the IEEE 802.16j has the additional security weakness caused by the requirement of backward compatibility for mobile stations of the conventional IEEE 802.16 system. In this paper, we propose a novel mutual authentication scheme applicable to IEEE 802.16j-based mobile multi-hop relay network architecture. The scheme is able to resolve the initial trust gain problem of a multi-hop node at its entry to the network, the problem of rogue mobile multi-hop node and the problem of hop-by-hop authentication between multi-hop nodes. Effectively, the scheme is a hybrid scheme of the distributed authentication method and the centralized authentication method which have been considered to be deployed in the wireless ad-hoc network and the wireless network connected to wired authentication servers, respectively. Also, we analyze the effectiveness of the proposed hybrid authentication method.
