This study aimed to investigate present status of online reference shelf and analyze access point in the home page and types of online reference sources in the university library. Data were collected by accessing home pages of 41 university libraries in the region of Seoul and Kyonggi-Do. 30 libraries had prepared reference shelf out of 41 libraries, and "User Service", "Electronic Reference Sources", or "Reference & Information Sources" were mostly used as home page menu. Types of references sources varied among libraries, and "Directories", "Dictionaries", "Statistics" or "Encyclopedias" were mostly loaded types in the reference shelf. For the enhancement of reference services through reference shelf, establishing and applying standards for evaluation, ease of access, access by subject, and continuous updates and additions of reference sources were suggested.

The overall goal of this study is to identify what I'||'&'||'R is, and what services should be offered as legitimate I'||'&'||'R actives. The gist of the study is as follows: 1. The shift of the clients targeted to receive the services from disadvantageous to every person. 2. Ambiguity in I'||'&'||'R definition. Because it is hard to distinguish I'||'&'||'R service from the traditional reference service, and shifting of clients, the establishment of the definition was very difficult. Instead of a definite answer, the criteria for "I'||'&'||'R Providers" was drawn. 3. Most provided services were simple and complex information giving based on resource file. Constructing resource file is a major component of I'||'&'||'R service. 4. From 1980s, many I'||'&'||'R providing libraries adapted computer a n.0, pplications. 5. Social work and library-internship was advised to conduct a cooperative project by NCLIS, I'||'&'||'R Task Force. 6. In the high technological era, there continue to be many people who need the su n.0, pportive relationship. I'||'&'||'R is to optimize both the service and clients. Librarian must learn from the principle of high tech/high touch.

As smart phones have become widely adopted, they have brought about changes in individual lifestyles, as well as significant changes in the industry. As the mobile technology of smart phones has become associated with all areas of industry, it is not only accelerating innovation in other industries such as shopping, healthcare service, education, and finance, but is also creating new markets and business opportunities. The preparation of thorough security measures for smart phones is increasing in demand. While offering excellent mobility and convenience, smart phones can be exposed to a range of violation threats. In particular, it is necessary to make efforts to develop a security system that can preemptively cope with potential security threats in the banking service area, which requires a high level of reliability. This paper suggests a security reference model that is considered for the smart phone-based joint mobile banking development project being undertaken by the Bank of Korea in 2010. The purpose of this study is to make a security reference model for a reliable smart phone-based mobile financial service, by recognizing the specific security threats directed toward smart phones, and providing countermeasures to these security threats. The proposed mobile banking security reference model is useful in improving system security by systematically analyzing information security threats to the mobile financial service, and by presenting the guideline for the preparation of countermeasures.

As affective barriers to library and information use, library anxiety(Mellon, 1986) has been studied in reference/information services and bibliographic instructions. The paper revisits Mellon's theory of library anxiety and Bostick's(1992) Library Anxiety Scale(LAS) in the digital library environment. In particular, this study attempts to address the inadequacy of the continued applications of LAS in the digital library environment, although the scale has been used unquestionably as the instrument measuring library anxiety. This contention was substantiated by three service trends in digital libraries(i.e., digital reference services, remote access, and transition from bibliographic instructions to information literacy) and by re-analyses of published library anxiety research papers in recent years. This study addresses the need for scale development that could measure anxieties of digital library users. It also suggests Information Literacy Anxiety Scale(ILAS) as a direction for the new scale.

The author discusses the nature and scope of archival reference service through the debate to user studies in the 1980s and the 1990s. Until the 1990s, archivists paid little attention to studying their user population. A new approach to archival user service led to the development of various public services of archives and resulted in active interaction with the public. Based on the discussion, the article examines the implication of archival reference service in Korean society.

The paper will give an overview of the mission of GalTeC and then concentrate on two main aspects. The first more detailed aspect, is the analysis of the key performance parameters for the Galileo system services and presenting a technical overview of methods and algorithms used. The second more detailed aspect, is the service volume prediction including service dimensioning using the Prediction tool. In order to monitor and validate the Galileo SIS performance for Open Service (OS) and Safety Of Life services (SOL) regarding the key performance parameters, different analyses in the SIS domain and User domain are considered. In the SIS domain, the validation of Signal-in-Space Accuracy SISA and Signal-in-Space Monitoring Accuracy SISMA is performed. For this purpose first of all an independent OD&TS and Integrity determination and processing software is developed to generate the key reference performance parameters named as SISRE (Signal In Space Reference Errors) and related over-bounding statistical information SISRA (Signal In Space Reference Accuracy) based on raw measurements from independent sites (e.g. IGS), Galileo Ground Sensor Stations (GSS) or an own regional monitoring network. Secondly, the differences of orbits and satellite clock corrections between Galileo broadcast ephemeris and the precise reference ephemeris generated by GalTeC will also be compared to check the SIS accuracy. Thirdly, in the user domain, SIS based navigation solution PVT on reference sites using Galileo broadcast ephemeris and the precise ephemeris generated by GalTeC are also used to check key performance parameters. In order to demonstrate the GalTeC performance and the methods mentioned above, the paper presents an initial test result using GPS raw data and GPS broadcast ephemeris. In the tests, some Galileo typical performance parameters are used for GPS system. For example, the maximum URA for one day for one GPS satellite from GPS broadcast ephemeris is used as substitution of SISA to check GPS ephemeris accuracy. Using GalTeC OD&TS and GPS raw data from IGS reference sites, a 10 cm-level of precise orbit determination can be reached. Based on these precise GPS orbits from GalTeC, monitoring and validation of GPS performance can be achieved with a high confidence level. It can be concluded that one of the GalTeC missions is to provide the capability to assess Galileo and general GNSS performance and prediction methods based on a regional and global monitoring networks. Some capability, of which first results are shown in the paper, will be demonstrated further during the planned Galileo IOV phase, the Full Galileo constellation phase and for the different services particularly the Open Services and the Safety Of Life services based on the Galileo Integrity concept.

Life log started with the simple purpose of recording or sharing mainly data regarding one's personal life, but with the introduction of advanced specialized analytic methods by many corporations, a new type of business based on the life log recently emerged, with an aim of improving the quality of people's personal lives. In spite of the indispensable advantages, however, personal health lifelog service brings critical challenges that cannot be avoided from user side if the security of the data is concerned. The problem of user's privacy infringement and leaking user's sensitive medical information is increasing with the revitalization of personal health lifelog services. In this paper, we propose an information security reference model for the personal health lifelog services. Our proposal can contribute to increase the related industry to cultivate new market by suggesting the clear announcement of the guidelines using privacy protection reference model for user-specific healthcare services which uses personal lifelog.

Due to the large size and high complexity of modern buildings, the interest and the studies about indoor spatial information are increasing. Previous studies related to indoor spatial information were mostly about relevant technologies, and the application of indoor spatial information has been less studied. In the present study, the public administrative work areas where indoor spatial information may be applied were identified by using a modified delphi technique. And the indoor LOD (Level of Detail) and indoor positioning accuracy for indoor spatial information applications considering user requirements was established as standards for efficiently establishing and providing services. The required LOD and positioning accuracy for services was established by reestablishing indoor LOD and positioning accuracy and classifying services with reference to those. The indoor LOD was reestablished from LOD 0 to 4 by focusing on service utilization and general recognition, and the positioning accuracy was reestablished in three levels by considering the accuracy of the present positioning technology and service utilization status.
