Speech DB is basically required factor when we are study for phonetics, speech recognition and speech synthesis and so on. The quantity and quality of speech DB decide the efficiency of system that we develop. therefore. speech DB has an extremely important factor, Recently, development of the various telephone service technique such as voice portal. it is actual condition where the necessity of collection of telephone speech DB. The existing IVR application telephone speech DB collection system used C/C++ language or the exclusive development tool. Thus it is the actual condition where the recycle of each application service for resources is difficult and have a problem of many labors and time necessity. But. VoiceXML is a language having tag form ipredicated in XML. which has easy and simple grammar system. Therefore, if we make a few efforts we could draw up easily. it has a merit reducing labors and time, Also, VoiceXML has many advantages of various telephone speech DB gathering because of changing contents of DB. In this paper, we introduce telephone speech DB gathering system which is the mast important factor for development of speech information processing technique.

Underground facility DB that is constructed by NGIS project need efficient management methodology, because falling-off in quality was worried by confused of existing management affair and management affair of computerization environment. Through analysis of existing management affair, underground facility DB and management system decide that modification/renewal factor of underground facility DB and subject affair Through modification/renewal factor of underground facility DB, developed underground facility DB management methodology using MMS. Result that apply developed management methodology to subject affair, existing affair environment improved to computerization environment and Could improve underground facilities DB authoritativeness.

해양생물다양성 자원에 대한 국가 주권을 인정하는 해양생물다양성협약의 발효로 생물다양성 자원을 확보하기 위한 세계 각국의 경쟁이 치열한 상황이다. 현재 우리나라 각 기관 및 대학들이 보관하고 있는 해양생물자원 정보가 산재되어 있고, DB에 대한 관리 미흡으로 인하여 학술적, 산업적 활용이 어려운 상황임을 인지하여, 통합적으로 관리할 수 있는 정보체계가 필요한 시점이다. 본 논문에서는 해양생물다양성 자원 중 고품질 해양생물자원에 대한 현황을 분석한다. 그리고 해양생물다양성 데이터 고품질 확보 방안을 위한 DB 품질 오류율 산정 기준을 적용하여 메타DB 구축 방안을 제시한다. 본 연구는 향후 해양생물자원에 대한 국가전략수립에 기여할 것으로 기대한다.

The National Science and Technology Information Center (NDSL) database, which provides academic papers at home and abroad, collects, builds, and manages data collected from various sources. In this study, we analyzed the DB paper schema and DB metadata that are currently constructed and managed to derive an integrated DB schema that can manage the high-value-added papers and manage them efficiently by analyzing distributed DB papers. Also, the final academic information data items were determined through comparison and analysis using the Web of Science and SCOPUS schemas that are currently purchased and possessed. The academic information data items constructed and serviced through this study were summarized into seven papers, authors, abstracts, institutions, themes, journals, and references, and defined as core contents under construction. The integrated DB schema was created through this study, and the results of this study will be used as a basis for constructing the integrated DB collection of high quality academic papers and designing the integrated system.

The national management and retrieval service of the national scholar Content DB are very important. High quality content can improve the user's utilization and satisfaction and be a strong base for both the citation index creation and the calculation of journal impact factors. Therefore, the system is necessary to check data quality effectively. We have closely studied and developed a webbased data quality checking system that will support anything from raw digital data to its automatic validation as well as hands-on validation, all of which will be discussed in this paper.

The goal of this study is to seek for the method of effective DB conversion and related system development for the integrated KORMARC Format on the basis of the case of Sogang University Library. Since the integrated KORMARC bibliographic format was established, libraries have been converting bibliographic DB according to the new format. Loyola Library of Sogang University internally proceeded DB conversion using bibliographic DB convertor, which was developed and customized with a system vendor for Sogang University Library. The internal conversion enabled to correct or supplement bibliographic data errors. Besides, it enhanced stability of conversion and shortened the project time by adopting sampling conversion method. It was effective to reduce the additional work for DB quality maintenance, so this kind of conversion is recommendable to the library that has limited manpower for manual data correction.

This study mainly concentrates on the development of a land information management system to manage the land related information in an effective way for the water-pollutant buffering zone, which was established to sustain better quality of the drinking water over the upper part of the Han river. For developing such system, a procedure was implemented covering user requirement analysis, system design, spatial DB design, and coding. DB linkage with affiliated institutes and cadastral DB updating were proposed as the part of the efforts to enhance the applicability of the system. In addition to that, modularization was adopted for more efficient and cost-effective system development.

Concrete quality is mainly managed through the reliable prediction and control of compressive strength. Although related industries have established a relevant datasets based on the mixture proportions and compressive strength gain, whereas they have not been shared due to various reasons including technology leakage. Consequently, the costs and efforts for quality control have been wasted excessively. This study aimed to develop a web-based numerical model, which would present diverse optimal values including concrete strength prediction to the user, and to establish a sustainable database (DB) collection system by inducing the data entered by the user to be collected for the DB. The system handles the overall technology related to the concrete. Particularly, it predicts compressive strength at a mean accuracy of 89.2% by applying the artificial neural network method, modeled based on extensive DBs.

This paper describes the reduction of DB without degradation of speech quality in Corpus-based Speech synthesizer of Korean language. In this paper, it is proposed that the frequency of every unit in reduced DB should reflect the frequency of units in Korean language. So, the target population of every unit is set to be proportional to their frequency in Korean large corpus(780K sentences, 45Mega phonemes). Second, the frequent instances during synthesis should be also maintained in reduced DB. To the last, it is proposed that frequency of every instance should be reflected in clustering criterion and used as criterion for selection of representative instances. The evaluation result with proposed methods reveals better quality than using conventional methods.
