The purpose of this study is to apply the Servicescape, which is used to measure the spatial services in marketing, to the studies on university libraries, in order to identify the influence of the library spaces and facilities on the satisfaction and continuance intention of the users of university libraries. For this purpose, questionnaires and in-depth interviews were conducted for users in ten private universities located in Seoul. Servicescape factors of the libraries showed that cleanliness, comfort, aesthetics, and convenience had a significant influence. Of these, convenience turned out to have the highest level of influence upon satisfaction, followed by cleanliness, aesthetics, and comfort. Descriptive statistical analysis showed whether there were significant differences in satisfaction and continuance intention based on the differences in the characteristics of the samples. Findings show that it would be necessary to provide spaces that can accommodate the various functions of a university library; seek advancement of the services; and develop the spaces of a library in consideration of cleanliness, comfort, aesthetic, and convenience. This study introduced the concept of Servicescape for the first time in the field of library and information science. This study implies that the results assist a more detailed analysis for the Library as Place dimension of LibQUAL+, and provide a new guideline for practitioners who design library spaces.

A network neutrality is the concept that ISP assures users non-discrimination, interconnection, accessibility for ensuring users without control or interference of equal services in the network. But today a network traffic is growing rapidly in sensitive buffering services as P2P service diffusion and mass video stream service. To manage this problem, ISP violates a net neutrality by control, change and interfere with service. And then the debate about net neutrality is happening. Therefore in this paper, we compare and analyze net neutrality principles, concepts, and legislative policy in the native and foreign. Based on this, we suggested the issues and improvement plan of net neutrality guard line.

Signage can be defined as the media device that provides specific information to many unspecified users in public places. Recently applied context-aware technology, signage provides personal on-demand information services in a way that can continue to evolve. The purpose of this study is to analyze characteristics of types which users identify signage on the perceptions and attitudes about consideration of the perspective of the experts in the fields. The research is carried out by applying Q methodology with in-depth interview. First, interviews are conducted to determine the perceptions and attitudes of experts and practitioners on signage. Thereafter users' perceptions and attitudes toward signage are classified by each types using Q methodology. The first type is named as 'signage as smart media', the second type is named as 'signage as passive media', and the third type is named as 'signage as interactive media' is named. The results of this study will be useful guidelines for conducting further academic researches and R&D.

The purpose of this study is to compare the national quality regulation schemes among four countries, and to find out implications to Korean quality regulation system of social services. For this, this study fixed comparative criteria on national quality regulation schemes, and compared the quality regulation schemes of 4 countries such as England, United States, Singapore and Japan. By reviewing prior relevant studies, three criteria could be suggested.: the level of user centeredness, the effectiveness of regulatory enforcement and stability of operation system. All analysed nations share similarities in that they all eager to provide quality information to their service users and develop nationally acceptable quality standards of social services. On the contrary, differences are identified in the level of regulatory enforcement and establishment of independent body for national quality control. By these results, this study discussed the meaning of these findings and their implications on the development of Korean quality regulation system.

블로그는 현재 광범위하게 대중성을 얻고 있는 온라인 커뮤니케이션의 최근 형태이며, 블로그 사용이 빠른 속도로 주류를 형성해 나가고 있다. 초기 HCI 분야에서의 온라인 커뮤니케이션(CMC)에 대한 연구는 사용자가 시스템의 소프트웨어나 하드웨어의 인터페이스를 어떻게 대하는가 하는 점에 초점이 맞춰졌었지만, 최근에는 온라인 커뮤니티, 블로그처럼 사용자들이 인터넷을 통한 사회화가 어느 때보다 활발하게 이루어지고 있기 때문에, 시스템의 사용성에 대한 고려만으로는 충분하지가 않다. 즉, 시스템이 어떻게 사용자들 간에 사회적 상호 교류를 지원할 수 있고, 이러한 사회적 교류가 원활하게 이루어지기 위해서 시스템이 어떻게 설계되어야 하는 지에 대한 이해가 필요하다. 따라서 본 연구에서는 실제 블로그 이용자들을 대상으로 이들과 상호 연결된 블로거들과의 온라인에서의 관계적 행위를 살펴보고, 또한 이러한 행위가 네트워크 구조적 특성과는 어떠한 상관 관계를 가지는지를 심층 인터뷰와 사회 네트워크 분석법을 이용하여 탐색적으로 알아보고자 한다. 본 연구 결과를 통해서 얻은 사용자들의 온라인 교류 시 보이는 행위적 특성을 바탕으로 온라인 개인 미디어 서비스 설계에 대한 가이드라인을 제안해 보고자 한다.

The purpose of this study was to investigate the information display at Yong In University through the use of field observations and surveys to improve the facility that adheres to the user's comfort and accessibility. The study has found that the arrangement of importance of subjects that are more relevant to the intended audience and the placement of the information kiosk at places where people would stay for longer durations have higher chances of absorbing the information provided in the kiosk. Though the study has been investigated in a limited setting of Yong In University, the broader implications of this study can be extend to public spaces that also provide information kiosks.

The government is pursuing a policy to remove plug-ins for public and private websites to create a convenient Internet environment for users. In general, financial institution websites that provide financial services, such as banks and credit card companies, operate fraud detection system(FDS) to enhance the stability of electronic financial transactions. At this time, the installation software is used to collect and analyze the user's information. Therefore, there is a need for an alternative technology and policy that can collect user's information without installing software according to the no-plug-in policy. This paper introduces the device fingerprinting that can be used in the standard web environment and suggests a guideline to select from various techniques. We also propose a user authentication model using device fingerprints based on machine learning. In addition, we actually collected device fingerprints from Chrome and Explorer users to create a machine learning algorithm based Multi-class authentication model. As a result, the Chrome-based Authentication model showed about 85%~89% perfotmance, the Explorer-based Authentication model showed about 93%~97% performance.

As the privacy issues are all around the world, the intrusion into personal privacy is concerning. For that reason, government established the article from the personal information protection law that has to notice the privacy policy to users on the online site. and the matter of privacy invasion make concern toward behavior of online user. Although there are rules to carrying legal binding force in accordance with, because it is full of text and uncomfortable to read so that its readability is low. In the same context, each other has different state of understanding with the policy for personal information has been playing an important role. In this approach, companies and government do not think this over deeply and do just for what their practical use is. That is the reason why this research start, and the result expecting for real. As the result in the participant who cognize the privacy policy display pattern, they have certain type to do. In this article, the certain behavior doing is remarkable with the privacy policy. According to privacy concern, privacy fundamentalist reveals such a compromise reaction to protect their information when they know what information which the privacy manager of service provider collect. This study arrives at the result depending on the gap of privacy group that the group of checking the policy contents, especially the group which has high privacy concern, they move forward to protect their emotion and put a constructive plan into protective action. Otherwise, the group of unchecking the policy contents and following their own thinking of privacy policy are not deemed statistically significant. Therefore, this is considered to support more various implications than the previous issues and alternatives about privacy policy pattern and user protection behavior of privacy.
