This study aims at preparing the foundation for continuous development of Topographic DB by suggesting an actual quality improvement scheme and proposing a draft for complementing existing progress and method of implementation and management according to this scheme. For this purpose, we surveyed the Topographic DB users to grasp the current DB quality and the required quality level. Then, the suggested quality improvement scheme was concertized and verified through an experimental research. The experimental research was concentrated upon evaluating primitive data, modifying geometrical and logical errors and management. At last, a plan to improve the related systems was proposed.

The research purpose for this study is to evaluate the quality of the KOLIS-NET DB which builded bibliographic data of the holding collections of nationwide public libraries. The quality evaluation of the KOLIS-NET DB was inspired by the successful experience from researches precedent and tried to approach the case study focuses on six quality dimensions : coverage, duplication. currentness. accuracy, consistency completeness. The study verified comprehensively the quality of the KOLIS-NET DB through a quality evaluation model and analyzed the factors causing such inferior and substandard bibliographic records in the KOLIS-NET DB. Based on the results of the quality evaluation, the quality improvements of the KOLIS-NET DB was suggested.

Recently, the Design-Build (DB) delivery method in public sector makes some argument by reason of the initial cost which is more higher than those of Design-Bid-Build (DBB). According to the results of pervious researches related to the performance evaluation of delivery method, DB can lead the reduction of project cycle time and also is superior to the traditional DBB in terms of construction quality. The performance on each delivery method could be generally evaluated by a project cost and a project cycle time as one of quantitative analyses, and also by construction quality as one of qualitative analyses. In most researches, the evaluation of performance level based on delivery methods has been evaluated by the degree of their satisfaction through the interview with owners. Therefore, this paper analyzed the design documents of construction projects delivered by traditional DBB and DB in bridge construction projects in order to measure design quality, constructability, maintainability, and etc. As an above-mentioned analyses, finally, this research shown that how much the difference of performance level is by each delivery method.

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 study aims to development of web-based process management system for spatial data construction. For developing this system work classification of basic surveying was standardized and quality management method for spatial data was established. Production process and work classification system for basic surveying such as control point surveying using GPS, leveling, aerial photographing, digital mapping, topographic mapping, digital elevation modeling, aerial photographic DB construction and digital orthophotomap was standardized. The status of the output and quality inspection for basic surveying project were analyzed, and the elements of quality inspection and data format for the type of outputs were analyzed. Based on standardized and analyzed contents, web-based process management system was developed after database and process was designed. The process management system consisted of process management, quality control, metadata management, and system management.

This study intends to evaluate the quality of the Digital Library System DB and to suggest methods for its quality control. The evaluation criteria are hit rates, redundancy, completeness and accuracy. In spite of high hit rates excessive records representing one work resulted serious redundancy. The average completeness rate of records was $48.12\%$ due to low level of description. The Analysis of accuracy showed various errors in most of records corresponding to $92\%$. Emphasis on analysing the errors in detail detected the causing factors and suggested practical guidelines for school libraries' catalogers.

기업의 ESG 활동의 일환으로 탄소중립과 순환경제의 개념을 활용한 기업의 성과를 고객에게 알리기 위하여 고품질의 전과정평가 결과에 대한 요구가 커지고 있다. 이를 위해서 LCI 데이터베이스에 대한 글로벌 요건에 맞는 고품질의 LCI 데이터베이스를 구축하고 관리하는 것이 국가적으로 중요하게 인식되고 있다. 이를 위해 UNEP는 GLAD 플랫폼을 만들었고, EU는 LCDN 플랫폼을 만들어 국제통용성을 고려한 고품질의 LCI 데이터베이스를 관리하려는 노력을 하고 있다. 국내 LCI 데이터베이스는 정부주도로 1999년부터 지속적으로 개발되어 활용되고 있지만, 국제통용성의 측면에서 볼 때, 기업의 생산현황을 반영한 최신의 일차데이터가 부족하고, LCI 데이터베이스에 포함된 목록항목들이 모든 환경영향을 충분히 평가할 수도 없으며, 데이터 정보제공의 형식인 LCI 데이터베이스 포맷이 글로벌 동향을 충분히 반영하지 못하고 있다. 이에 국제통용성을 고려한 국내 LCI 데이터베이스의 개발을 위해 산업을 대표하는 협회 또는 단체를 통해 매년 최신의 일차데이터를 확보하고, 이를 토대로 모든 환경영향을 평가할 수 있는 수준의 목록항목을 포함한 국내 LCI 데이터베이스를 개발하고, 이를 Eco-SPOLD_02 또는 ILCD 등의 최신 LCI 데이터베이스 포맷으로 관리하여야 한다.

This study aims to standardize the work classification system in spatial data. Up to now, a systematic standard for constructing process and quality management has not yet been established in Korea, thus, it is possible for the national budget to be wasted. The regulations related to constructing spatial data are also obscure, and absurd for feasible application to reality, which results in a lack of reliability of the quality of spatial data. This study was conducted by investigating and analyzing regulations related to spatial data quality and various literature, including studies on spatial data quality conducted by the NGII. And also, the study was conducted by investigating and analyzing the constructing processes and working methods of major firms that have experience in constructing a GIS for a local governing body. Based on the analyzed data, we standardized work classification and management methodology for control point surveying using GPS, leveling, aerial photographing, digital mapping, topographic mapping, digital elevation modeling, aerial photographic DB construction, digital orthophotomap.
