This focuses on the Cultivation Plan Service at the preliminary production phase is critical in that it supports agricultural producers' decision by providing related information such as predicted crop production or expected profits for consulting or other agricultural information when they plan to cultivate. This paper describes the reference architecture of the farming sector will benefit immensely from the implementation of farming data in farming contents repository which will serve as the knowledge base for the Cultivation Plan Service at the pre-production stage based on Big data analysis.

This study is aimed at providing qualitative evaluation of information supplied by reference librarian in response to researchers' questions. Information users' satisfaction on the appropriateness of librarians' answers was evaluated, and at the same time, negative factors affecting users' satisfaction were examined, so that improvement of service quality and information appropriateness can be sought by analyzing the influences and correlation between these factors. For this study, information centers at ten professional research institute carrying out government-related projects were selected, and data were collected using unobtrusive evaluation methods through observation and questionnaires. Collected materials were analyzed using SPSS/PC+' statistical analysis programs and $\chi^2(Chi-square)$ statistical methods.

Information service for the aged is a new challenge for public libraries in Korea. To develop an internet-based information service at public library perspectives, information sources, information need, and information seeking and using behavior are investigated. Interview survey is performed to 1060 adults aged 60 and over. Finding revealed that the respondents led to few channels to information except for mass media and informal oral communication. It ascertain ways in which 23% of the respondents currently use internet, and identify barriers of nonusers. The information need of the elderly are diverse, but health/medicine, news, hobbies, religion, leisure/travel are most identified need in descending order. Based on data analysis and previous research results, a cooperative service model consisting of information contents, online reference, interface design, and education is developed. Finally problems and suggestions for future improvement are discussed.

The current technological revolution pushes forward the innovation in the library information systems. This study proposes functional requirements and an architectural reference model of Semantic Library, recognized as a prototype of next-generation library information systems, that is a seamless convergence of the library information systems and the Internet technologies. Semantic Library can realize semantic interoperability and integration based on ontology and metadata, and also renovate information services for users with openness, sharing, participation and collaboration. Semantic Library will be effectively implemented by means of service-oriented architecture and the logical structure of FRBR. In this study, a reference model of Semantic Library consisting of 6 horizontal layers and 3 vertical elements is presented as a next-generation model of library information systems.

The following results have been driven out from a survey of the actual conditions of the public libraries service in Korea, made through questionnaire in reference with the actual service for youth that are presently done by the foreign countries' libraries, in order to prepare a perfect and objective base in establishing a service activities of the public libraries in this country: (1) It was found that the public libraries' loarning hours during the week days which accords with the schooling hours of the schools are shown to 50 %. On Saturdays during Summer season seven libraries and during Winter season twelve libraries would close their loaning before 17 : 00 hours, and on Holidays and Sundays fifteen libraries are not doing their loarning. (2) The followings are the present status of the service activities for the youth by the public libraries: a. It was found that they do introduction activity (50 %) of newly published books as a service for inducing reading interestings of the youth, and except this it was found that others are on beginning. b. The service activities by the data for the visual and auditory sense are almost negelected. and the rate of doing such activity is shown to 9.74%. c. It has been found that little information service activity is for inducing the youth to the libraries. d. As a cooperative activity with the school's, a passive service activity to have pursuaded to visit the public libraries by each class, are mostly being done (27.27%). Some research meeting for solving all the matters between the school libraries are not held mostly.

To deal with a new environment of information technologies in the 21 Century, many libraries around the world have made great efforts to develop online knowledge-information services. In Korea, the National Library initiated an online knowledge-information services, in 2008. Through case studies and practical tests of online knowledge-information services, this article discusses plans for developing . The article explores definitions and types of online knowledge-information services, and analyzes online knowledge-information services in Denmark, Sweden, Finland, and Korea. Futhermore, practical reviews on the four services are conducted through 'question-answer' tests. As a result, the article discusses present and future tasks for improving .

Question taxonomy is one of main approaches to understand the questioner's information need so that we can assign relevant answerers to the question submitted by the user. The goal of this study is to investigate question taxonomy of question and answering services, which are available online and in libraries and understand the characteristics of question answering services by type. In order to achieve the goal, this study examines the types of questions appeared in literature, specifically focusing on social reference, question answering systems, and reference services, and then provides a summary of question taxonomy found in question answering services.

With the purpose of looking into the information service study tendency, targeted at university library, this performed a content analysis of the articles in print from 2006 to 2015 on major four academic journals of Library and Information Science. Investigation items were study number of information services, subsidiary themes classified with information service functions, study method, collection method, user object, and theory study vs. service study in reality. As a result, information service studies were performed more than other areas. Information service functions targeted at the study were that of information supply. Major subsidiary themes were electronic information service, information literacy instruction, and information (reference) services general. Major study methods were survey research method,, case study, and major material collection methods were questionnaire and web-based research methods. Major user studies were targeted at undergraduates, and service study in reality took a great share.

The stability of DGPS signal in the DGPS service area was measured and the service availability according to the receiving signal strength was analyzed in this paper. Based on the effects of radio wave propagation in the seasons of winter and summer, daytime and night, the method to provide the DGPS service coverage was presented in this paper. The signal's strength of DGPS radio wave were measured at a constant distance from the DGPS reference station during a constant period. The propagation of DGPS radio wave is affected by status of ground conductivity, so the DGPS service area is dependant on the ground conductivity. To provide the stable service coverage, it is necessary to apply the adaptive power control for receiving signal's variations and the antenna design for alleviation of high elevation's radiation.
