This study is to suggest the ways to make the education in Library and Information Science more professional and more practical by going through the problems in the curriculum of Library and Information Science in the aspect of 'reference service'. For this purpose, the curriculum changes of 32 domestic universities offering Library and Information Science between 2005 and 2009 was analyzed and compared with the current situation of the U.S. The research has revealed some problems. First of all, it shows that the subjects such as the introduction of or the theory of library and information science still comprise a large portion of the domestic curriculum. Additionally, there seems to be much difference in the number of subjects between the universities. Lastly, there are few subjects which consist of the observation and understanding of the library field, and participation therein. Therefore, to operate the 'reference service' curriculum effectively, it is necessary to offer courses for understanding the users and subjects and for the reference service. In addition, it is necessary to strengthen the practical education through a close connection with the library field. Finally, it is urgent not only to expand the subjects for improving the ability of user education and communication but also to make the curriculum of each university specialized.

The objective of this study was to promote the use of collaborative digital reference service by identifying factors that affect user satisfaction and developing improvement measures based on the findings. Data were collected via a questionnaire administered to the users of the "Ask a Librarian" service and a survey to analyze the frequency and patterns of usage of the service. The survey analyzed the associations among subjects' demographic characteristics, information seeking patterns, factors that influence user recognition, service satisfaction, and follow-up intentions via responses to the questionnaire. Rapidity answers in factors of service satisfaction is found that the high impact of positive (+). According to the result of statistical analysis, the priority of service improvement strategies of digital reference service were suggested.

The proper evaluation of reference services requires qualitative approach as well as quantitative one. The quality of a reference service can be evaluated by how promptly and accurately a librarian responds to the user's questions and also by how much the user is satisfied with the librarian's overall performance in providing the answer. In this study, the reference service of an university library was evaluated by the following procedure : 1. Identification of a group of the most frequently referred Korean government publications through two pre-tests of user surveys. 2. Preparation of 130 questions of bibliographic and factual type from the above publications. 3. Selection of 30 questions which can be answered from the collection of the evaluated library. 4. Mimic requests of reference service by 5 proxies trained on the unobtrusive test method with 30 questions asked at various times of the day and on various days of the week during a period of 5 months. 5. Drawing up of response sheets (by proxies) with descriptive comments on library staffs' question administration, response, attitude, etc. 6. Preparation and coding of data tabulation sheets and final analysis. The conclusions of this study are as follows : 1. The user serveys showed that needs for the library service for government publications were great. The $80\%$ of the government publications users were visiting more than two organizations for access to information and the $37\%$ were getting information directly from the publishers. 2. The librarians of the evaluated library could give correct answers to $53\%$ of 30 (bibliographic and factual) guestions. 3. The correctness of answer was independent of the length of the time spent the librarians. The librarians' grasp of the questions and direction of approach determined the success or failure of the service. 4. The librarians relied too much on the reference library catalog which doesn't include many of the government publications of their own collection. 5. The $79\%$ of the failure of the service were due to the librarians' lack of knowledge as to the information source for government publications and the unsystematic method of approach to it.

The existing wired emergency call such as 119, 112 have its own location information to serving immediate rescue service. For the case of wireless emergency call by mobile phone, the location information should be provided by wireless network. This paper describes the network architecture and protocol for mobile emergency service referring TIAlEWJ-SID-036-A with reviews about technical issues, legacy factors and related researches. The mobile emergency service is divided into mobile emergency rescue service and mobile emergency alert service. The network reference model for mobile emergency rescue service is released in KOREA. In this paper, the interfaces between elements of the network reference model, and service scenarios, message flows are defined. Supplement to mobile emergency rescue service, the network reference model, interfaces and message flows for mobile emergency alert service are developed. The protocol is described by DID, and the proposed works are on processing for domestic standard of TTA.

The purpose of this study was to obtain the various basic data for introduction of information and referral service in the Korean public libraries. For the purpose, this study was conducted by carrying out theoretical research on the concept and definition of information and referral service, the type and level of the service and the needs for introduction of the service in public libraries and using questionnaires with 242 public libraries(reference librarians) all over the country, so as to examine the librarians' views on the whole service. The questionnaire mainly included questions about actual status, present level and understanding level of the service, reference librarians' response to needs for introduction of the service, and type and level of the service available when the service has been introduced. In conclusion, this study will help to establish basic foundation, so that the Korean public libraries can realize equalization of the service and promote the information and referral service.

The purpose of the present study is to verify the two hypotheses: (1) Online services are fundamentally automated versions of the reference services. Accordingly there will be a major impact on reference services when Online service is introduced into the traditional library environment. The chief impact will be that the use of data bases retrieval service supplements and improves the traditional reference service when Online service is coordinated with the traditional reference service. and is fully incorporated into the existing user service areas. (2) The availability of data bases retrieval service will make it possible for the first time for the reference services to offer substantial search services of any kind resources limited to the printed sources. In light of such circumstances, libraries would provide better service to their users and greatly increase the productivity of reference librarians. There will be also the recognition that a result of an improved professional image for reference librarians and the library heightens user interest. This change may be translated into increased usage of library services generally. To achieve the purpose, 4 Research Libraries adopted Online retrieval from DIALOG's data bases-searching and reference services available in-house were chosen.

Wide-Area Differential Global Positioning System (WADGPS) is a system that operates a number of reference stations to provide correction information to improve the accuracy of GPS users, and it is available to service users within the area where the wide-area reference stations are installed. Recently, as positioning information has been used in various applications, the need for WADGPS for precise navigation in long-distance spaced areas where the wide-area reference stations cannot be installed has been raised. This paper tested the user navigation performance outside the wide-area reference stations of the WADGPS system, which serves both GPS Precise Positioning Service (PPS) and Standard Positioning Service (SPS) users. Static and dynamic tests were conducted using vehicles, and as a result, position accuracy improvement through WADGPS was confirmed even at points hundreds of kilometers outside the network area of the wide-area reference stations. Through this, the performance of the PPS/SPS correction system and the possibility of expanding the service area were confirmed.
