Information systems development entails planning, analysis, design and construction phases. The analysis phase identifying user requirements is the most important of these phases. Since unidentified defects in the early phase causes increased work and costs as development proceeds, the quality of analysis results affects the quality of the resultant system. Major tasks in the analysis phase are data modeling and process modeling. Research on building a knowledge-based system for data modeling have been conducted much, however, not sufficiently for process modeling. As a system environment with high user interaction increases, research on process modeling methods and knowledge- based systems considering such environment are required. In this research, a process modeling framework for information systems with high user interaction is suggested and a knowledge-based system for supporting the suggested framework is implemented. A proposed model consists of the following tasks: event analysis, process analysis, and event/process interaction analysis. Event analysis identifies business events and their responses. Process analysis break down the processes of an enterprise into progressively increasing details. Decomposition begins at the function level and ends when the elementary process level is reached. Event/process interaction analysis verifies the results of process analysis and event analysis. A knowledge-based system for supporting a proposed process modeling framework is implemented in a web-based environment.

With labor shortage and high-wage, the construction cost is rising and the construction-business is dull, demanding the construction environment of Korea to raise profitability through major cost savings and rationalization of construction management. Therefore, in this study, to improve many problems found in calculating rebar quantity for capital expenditure programming which is considered the beginning stage of rebar work. and to improve problems such as no grasping of rebar loss due to lack of systematic management in order/purchase stage and construction management stage, a rebar information-management-system was found and preyed. The relation database was designed for the rebar information management system by analyzing work process of a rebar manufacturing plant, as the rebar information that is necessary in a rebar manufacturing plant if similar to that of a purchasing department of general construction company. The Proposed rebar information management system was implemented in two large rebar production plants. The implementation of the proposed system showed that the system increased work efficiency, reduced the management manpower, and improved the project-integrated management

Industrial structure is more developed, the economical value of human resources and the cases which risks worker's Health & Safety is expended. The Safety & Health issues are focused on elements of control for management activity simultaneously with work environment as well as the risk elements which risks worker's life and body. The activity for combination of basic management System and Safety & Health management is progressing with active discussion in ILO, BS 8800 is specified the guidance of Occupational Safety & Health Management System in UK. 1996. This research refers to BS 8800:1996, specification as a basic model, and introduce of the result of certification development result in Occupational Safety & Health management System with in ISO 14001 Environmental System Standards & ISO 9001 Quality Management System Standards and Systemic Factors. Through this applicability and efficiency evaluation, we make an effort to support and to improve the specification. Also applicability evaluation of Occupational Safety & Health management System and the specification developed for the purpose of the third party certification is applied with expending in industry, and the method is presented through the case which is required to support for method review and activities.

With embedded computing technology makes progress , various applications have been developing in PDA. And information exchanging through U document is underway actively between applications in internet environment. But most of the embedded system has Poor hardware resource. And embedded system uses own file system for XML document management. For reason of, it occurs to many of difficulties of data share and information exchange among other systems. Therefore, an importance of the XML Document Database Management System is on the rise in the embedded system. In this Paper, we design and implement Embedded XML Document Database Management System(EXDMS) for efficiently management of XML document and supporting data sharing and information exchanging through XML document in embedded system. As compared with file system, EXDMS shows results that more excellent performance about expandability and compatibility of application. Also, EXDMS has an excellent data Processing performance in poor system environment.

The building section is providing immediate causes for global climate change problems since it takes about 50% of carbon emission, 20~50% of waste discharge, 33% of energy consumption, 40% of resource use, and 17% of water consumption. So, many countries over the world have developed and implemented green building certification systems to assess sustainable performances of buildings since the early 1990s. In korea, the green building certification system to induce the diffusion of sustainable buildings was first introduced in 2002 and developed as an improved version of the G-SEED(Green Standard for Energy and Environmental Design) system in 2013 after major revisions of related legislations. This research conducts a survey targeting residents on an apartment building that was certified as green building and examines the importance of assessment criteria on apartment buildings to certify green buildings using the Analytic Hierarchy Process(AHP) method. And it proposes a new direction on certification assessment standards from the resident's prospective. As a result, assessment criteria such as indoor environment, ecological environment, energy & environment pollution, and maintenance management among 7 main ones turned out important on assessing the G-SEED system for apartment buildings, while criteria such as material & resource, water circulation management, and land use & transportation did relatively unimportant.

This study modifies the present total maximum daily load (TMDL) system of Ministry of Environment and applies to the Anyangcheon watershed. Hydrologic Simulation Program-FORTRAN (HSPF) model is used to simulate both runoff and non-point source pollution, simultaneously, instead of QUAL2E. The drought flow (355th daily flow) is proposed for the target water quantity since it is easier to satisfy low flow (275th daily flow) for the target water quality than drought flow. The increase of discharge is more than the increase of pollutant load except for the period under low flow. The measured unit loads for non-point source are used to consider the regional runoff characteristics. The measured water quantity and quality data are used since the ministry of environment supports only water quality. This analysis results show some reasons for the improvement of the present TMDL system of Korea.
