This study is aimed to examine the characteristics of library space, in which user experiences and social networking are central in its design. Today, a library is a place to provide diverse accesses and experiences to information networks, where various individuals and user groups come and share mutual understanding and experiences. Library users developed social ties and a sense of community through library experiences. As a multipurpose space of a community, a library has the characteristics of urban public space like sidewalks and plazas. The eight case studies of libraries are analyzed from the viewpoint of each factor of library experience, including landscape, sidewalk, and plaza experience. The study drew its conclusions as follows. First, a library is a regional landmark for the users. Thus, it tends to be designed to allow transparency on its surface which introduces inner and outer landscape into the inside of the building. Second, the users experience a library similarly as they experience an urban street where they interface, browse, and interact with people and information. As they interact and share experiences, they develop solidarity and social ties among them. A library is designed to preserve continuity to adjacent streets, which increases accessibility to the building and hosts street activities into the building. Third, a library today is designed to be a flexible open space with information networking as well as community networking which allows library users diverse activities within it. For example, a multipurpose grand stairs in the middle of the main circulation of a building allows the users diverse activities. A large open stack with reading areas gives the users the feeling of an urban plaza where they can move vertically and horizontally. In conclusion, all findings of this study imply a user-oriented design for a library building.

In the 21st century, both globalization and e-Transformation trends of business in China have been in progress simultaneously and very rapidly. Due to those phenomena, there is consequently big change not only in the field of political-economy but also in the cultural trend of the world. But, despite of the importance of mutual cooperation between Korea and China, the research about Chinese cyber culture is neglected relatively. The purpose of this study is to review the cyber cultural aspect of business between two countries, and to devise proper measures for cultural cooperation not only reengineering the role of two countries but developing mutual benefit in East Asia in the era of global competition. The methodology used in this study is basically depending on theoretical study. Major findings are as follows: China has some cyber-cultural characteristics like very big size of netizen, heaven on earth of counterfeit, deepening in digital divide, etc. And Chinese traditional off-line culture has changed as the cyber culture spreaded over in cyberspace recently. But, on the other hand, cultural trends are changed to homogeneity both in nation-side which is between Korea and China and in space-side which is between online and offline culture. It is recommended that Korea and China have to endeavor to understand mutual culture, and to utilize the cyber culture in the respect of business cooperation. Consequently, two countries should effort to prepare exchange program for both netizen group, to design culture-networking system, to strengthen cyber-cultural marketing, and to make good use of both Korean Cultural Wave(said Han-Ryu) and Chinese Cultural Wave(said Hwa-Ryu).

Network industry is complex combined with various fields of industry, such as communication, broadcast, construction, and home appliances. Moreover, it's fairly lucrative since the growth industry makes lots of added values, interacting with the others.The network industry, usually called 'Ubiquitous', connects some home appliances and makes an integrated system that you can use them with whenever and wherever. A demand for network security, however, has skyrocketed due to the relatively low safety. It's been expected that the market of home security is going to be grown up nearly 30 percent every year. Recently, analog surveilance cameras have been replaced with digital ones, and they will be providing stronger security services taking advantage of mutual interaction with related industies. In this paper, a mobile monitoring system for home security is proposed, which makes it possible to supervise all home appliances wherever you're, using the conventional wired/wireless network infra.

Mobile social networking applications are getting increasingly popular among today's mobile applications. Mobile users find their old or new friends anywhere or anytime through mobile social network (MSN) services. MSN uses matchmaking mechanisms to discover mutual interests among different people. To discover friends in MSN, a user must share his/her private information which can be a risk for his/her personal privacy as this information can be learned by a malicious or semi honest user. In this paper we give a brief survey on MSN that includes MSN categories, components, architecture and applications. In the rest of the paper we discuss the matchmaking protocols. Finally we give some suggestions to improve the previous protocols.

Wireless mesh networks (WMNs) provide an efficient and flexible method to the field of wireless networking, but also bring many security issues. A mesh point may lose all of its available links during its movement. Thus, the mesh point needs to handover to a new mesh point in order to obtain access to the network again. For multi-domain WMNs, we proposed a new ID-based signcryption scheme and accordingly present a novel ID-based handover protocol for mesh points. The mutual authentication and key establishment of two mesh points which belong to different trust domains can be achieved by using a single one-round message exchange during the authentication phase. The authentication server is not involved in our handover authentication protocol so that mutual authentication can be completed directly by the mesh points. Meanwhile, the data transmitted between the two mesh points can be carried by the authentication messages. Moreover, there are no restrictions on the PKG system parameters in our proposed multi-domain ID-based signcryption scheme so our handover scheme can be easily applied to real WMNs circumstances. Security of the signcryption scheme is proved in the random oracle model. It shows that our protocol satisfies the basic security requirements and is resistant to existing attacks based on the security of the signcryption. The analysis of the performance demonstrates that the protocol is efficient and suitable for the multi-domain WMNs environment.
