상수도시설은 준공후 관련지자체에 이관 관리하는 시설로서 사용관종이 현재 다양하게 생산 보급되고 있어 관종 선정시 다각적인 측면에서 검토하여 채택하여야 한다. 최근 한국토지공사에서 사용하고 있는 상수도 관종은 대부분 택지개발계획 등 인허가 당시부터 관리주체인 지방자치단체 등과의 협의과정을 거쳐 선정되는 경우가 많아 자재선택에 한계성이 있다. 이를 극복하기 위해서는 자재 성능에 대한 공사내 명확한 기준이 제시되어야 한다. 상수관종을 선정하기 위한 가장 중요한 요소는 경제성으로 판단되는데, 관종의 경제성은 시공비와 자재비를 포함한 단순 공사비에만 국한되는 것이 아니라 유지관리비용을 포함한 생애주기비용(LCC: Life Cycle Cost)을 평가하여야 한다. 따라서 본 연구에서는 한국토지공사에서 택지지구 조성을 위해 사용한 배수관.급수관용 상수관종에 대한 경제성 평가기준을 제시하였고, 평가기준에 따라 각각의 택지지구 조성사례별로 종합적인 경제성 평가를 수행하였다. 보다 풍부한 자료를 바탕으로 객관적인 경제성평가 기준을 수립하기 위한 전(前)과정으로 이해되길 바라며, 설계시부터 객관적인 평가기준을 통해 합리적인 상수관을 선정하여 지금까지의 상수관종 자재선택의 한계를 최소한으로 축소하고자 하는데 가장 큰 목표를 가지고 있다.

In this study, libraries of national and public universities, libraries of private universities, libraries of colleges, public libraries of local governments were selected to measure, compare and analyze the differences in job satisfaction of librarians working in different types of libraries. As for measurement items, 10 factors for job satisfaction were chosen. In doing so, this researcher compared and analyzed the overall job satisfaction and work satisfaction, employment satisfaction, satisfaction with promotion system, satisfaction with work distribution, satisfaction with payment system, satisfaction with service system, satisfaction with facility environment, satisfaction with educational training, satisfaction with welfare system, and satisfaction with personal relations. The results of the analysis on job satisfaction with each factor by librarians working in different types of libraries are presented as follows. First, the overall job satisfaction value of the librarians was 3.940, which means relatively high satisfaction, and in terms of a type of library, libraries of private universities showed the highest value, and the next ones were found to be libraries of colleges, public libraries and libraries of national and public libraries. Secondly, regarding the ranking of the overall satisfaction with the selected 10 job satisfaction factors by different types of libraries, educational training was found to rank the highest, and the next ones were surveyed to be the job, the service system, the personal relations, the employment system, the work distribution, the facility environment, the payment system, the welfare system, and the promotion system.

The design on a riser in 1MW OTEC system is performed. The minimum diameter of the riser is decided depending on intake quantity of deep-sea water to supply an OTEC cycle. An applicable pipe material is selected from analyzing the properties of commercial pipes. The selected HDPE pipe with the low density and strength is reinforced with a lumped block attached at the end of and wire ropes along the riser. A lumped block, connected to a floating structure by wire ropes, with 25% and 50% weight of a GFRP riser is designed to be attached the end of a riser. The structural safety of the HDPE riser with wire rope supporting axial loads induced by a lumped block is analyzed under the harsh ocean environmental condition near Hawaii ocean with the numerical method. The final dimension of the riser and accessories is determined considering the economic point of view. The designed riser will be applicable to the construction of the 1 MW OTEC pilot plant.

Do Korean researchers in the field of library and information science really provide practitioners with knowledge and information needed in their efforts to improve library and information services\ulcorner If so, to what degree do the researchers excercise such intellectual leadership in the profession\ulcorner This study is intended to seek answers to these questions. A sample of 589 administrators and librarians working in public, research and university libraries was requested to respond to the questionnaire posted in June of 1995. Data gathered from the responses were analysed to find how, for what purposes, to what degree, and what kinds of, research outputs in the profession practitioners utilize in their provision of services to users.

This study seeks to develop a curriculum operating model for Korean Library and Information Science, based on investigations into LIS curricula at home and abroad. Standard courses that can be applied to this model were also proposed. This study comprehensively analyzed the contents of domestic and foreign curricula and surveyed current librarians in all types of library fields. As a result, this study proposed required courses, core courses, and elective courses. Six required LIS courses are: Introduction to Library and Information Science, Information Organization, Information Services, Library and Information Center Management, Information Retrieval, and Field Work. Six core LIS courses are: Classification & Cataloging Practice, Subject Information Resources, Collection Development, Digital Library, Introduction to Bibliography, and Introduction to Archive Management. Twenty selective LIS courses include: the General Library and Information Science area (Cultural History of Information, Information Society and Library, Library and Copyright, Research Methods in Library and Information Science), the Information Organization area (Metadata Fundamentals, KORMARC Practice), the Information Services area (Information Literacy Instruction, Reading Guidance, Information User Study), the Library and Information Center Management area (Library Management, including management for different kinds of libraries, Library Information Cooperator, Library Marketing, Non-book Material and Multimedia Management (Contents Management), the Information Science area (Database Management, including Web DB Management, Indexing and Abstracting, Introduction to Information Science, Understanding Information Science, Automated System of Library, Library Information Network), and the Archival Science area (Preservation Management).

The objectives of this study are to examine changes in research on library marketing promotion from its introduction to the present using domestic journals carrying research papers on library marketing, to forecast research trends in the future, and to provide basic information for supporting future studies on subjects related to library marketing. There were a total of 3,951 papers published through the journals in the area of library and information science including 'The Journal of the Korean Society for Library and Information Science', 'The Journal of the Korea Biblia Society for Library and Information Science', 'The Journal of the Korean Library and Information Science Society', and 'The Journal of the Korean Society for Information Management' from their first issues to the present. These papers were searched using selected keywords, and after redundant papers and those not related to library marketing were excluded, 359 papers were sampled for this study and analyzed from different aspects. Findings derived from this study, with regard to trends in research paper publishing by year, with regard to trends in research paper publishing by institution, with regard to trends in research paper publishing by author, with regard to trends in research paper publishing by area, and with regard to trends in research paper publishing by library type.

Interceptor sewer is installed underground near to the river side mostly ofstate-owned land and the management efficiency of public sewage disposal facilities is decreasing as too much infiltration/inflow(I/I) and river flow to interceptor sewer are caused by broken or deteriorated sewer. This also affects the sewer pipeline project and decreases its efficiency. Therefore, the aim of this study is to investigate interceptor sewer which has influence on the reduction of the project effect. The investigation were performed for three study areas. The study includes the investigation of current condition of interceptor sewer(sewer extension, pipe diameter, pipe type, installed year, installed locations, etc), investigation of inside of sewer by CCTV accompanied by pumping and dredging works where required, investigation of inside of manholes by eyes, calculation of pollutant load using the results of investigation of flow quantity and quality. Multipoint investigations were simultaneously performed for flow quantity at confluence area and other investigations were also performed for flow quantity and BOD for interceptor sewer and comparison of pollutant load, investigation of infiltration/inflow(I/I) caused by deterioration of interceptor sewer. As the result of the study, a main reason for reduced effect of sewer pipe improvement project was analyzed as the low-density sewage and I/I in public seweage treatment Facility due to deteriorated and unmanaged interceptor sewers.
