Wireless network using dynamic IP and mobile IP technology provides the user with convenience of access and movement. However, this causes the attacker who disguises normal user(pretending to be a regular user) to have more opportunity in regard to access and acquisition of information. This paper help the network administrator and the service provider quickly to recognize the attacker's intention to access network and service. Therefore network administrator and service provider can specify and respond the location of the attacker appropriately. To achieve above, we define an entity (W_L_M) that manages user information of WiFi and LTE network, and propose messages and procedures for attacker's location identification and alarm. The performance evaluation of this paper is based on qualitative analysis. By using the proposed method, some cost (message creation, processing and transmission) occurred but it was analyzed to be less than the total network operation cost. The proposal of this paper is a management method that utilizes existing network information and structure. This method can be used as a reference material to enhance security.

With the advent of the autonomous driving era, automobiles are being discussed as an extension of the media. The growth of the in-vehicle infotainment(IVI) system can provide various benefits and values to the driver and passengers. Although the development and research of related technologies is being carried out, there has been no research that specifically identified users' valuation on the main attributes of IVI systems. This study uses conjoint analysis to investigate key attributes and users' preferences. The results indicate that the most important attribute for IVI system is provider, followed by system operation type, main service and content type. For each attribute, consumers prefer a detachable infotainment system provided by a telecommunication company, and prefer to use information-oriented services and content that they have previously consumed. This paper provides practical implications, especially in terms of convergence, that operators can refer to in IVI development.

There are many famous, well-known special collections built with unique and valuable materials in the libraries all around the world. These special collections are very important for the public and especially for the researchers. Digital access and the Web have altered the landscape of special collections and allowed increasing numbers of users to locate and access rare and valuable materials of special collections. This change has also affected libraries with the responsibility of building and managing special collections. The goal of this paper is to provide readers with insight into the culture of the special collection and to suggest good ideas for public libraries to build their special collections by introducing the special collection building cases in USA and Korea through investigating the public library websites.

The complexity to search a specific content over TV platform is drastically increasing. Based on previous studies from computer data management system, we propose a new method that helps users to search and select content effectively. In general, contents over computers are represented by spatial metaphor, which replicates our physical environment and value systems about space. We suggest 3D lattice structure to construct information space for TV platform. Users can infer relevance between contents via special clue in information space, so as to select content more easily. Also, they can search contents through its temporal property that also represented in space. We make full use of our natural capability that can reduce additional overload to learning new interface. The results of this study can be significant and heuristic contributions, as they can be applied to diverse service areas utilizing video contents.

Due to COVID-19, user instruction programs could not be conducted face-to-face, and the sessions have been moved online. The present study attempted to investigate how online user instruction influences the information literacy ability of college students. The study randomly selected college students (N=50) who completed online user instruction sessions and college college students (N=50) who did not complete them among freshment who went to to college in 2020 to measure their information literacy abilities. For this study, a tool for measuring information literacy abilities was developed by referring to several previous studies. The measurement results were analyzed by the independent samples t-test, and significant differences were found between students who completed online user instruction sessions and those who did not. The findings of the study have confirmed that it is effective in enhancing library users' information literacy abilities to provide user instruction online under the COVID-19 situation, and even in post-COVID 19 times, which helps them appropriately utilize the characteristics of digital libraries. The information literacy measurement tool used in the present study was developed to evaluate online information literacy, and thus contributed to the extension of the literature of digital information literacy and user instruction. The present study provided practical implications for how academic libraries will promote information services to cope with environmental changes in which contact-free (untact) services are obliged.

Science and technology contents (research papers, patents, reports) are the most common reference material for researchers involved in research and development in the fields of science and technology. Based on various search elements (title, abstract, keyword, year of publication, name of journal, name of author, publisher, etc.), many services are available for users to search science and technology contents and bibliographic information owned by libraries. Authority data on organization name can be useful as an element for author identification and as an element to search for results produced by specific organizations. However, organization name is not taken into account by current search services for domestic academic information and bibliographic records. This study analyzes organization name data contained in the metadata of science and technology contents, which are the basis of the establishment of authority data, and proposes a method and system based on string containment and exact string matching.
