The primary purpose of this study is to develop an automation tool capable of converting the specification of structured analysis into that of structured design. Structured Analysis and Structured Design Language (SASDL) is a computer-aided description language based on ERA model and particulariged by ISLDM/SEM. The automation tool utilizes the specifications of data flow diagram described in SASDL to produce their corresponding SASDL specification of structure chart. The main idea behind the automatic conversion process is to categorize the bubbles in data flow diagram and to determine the positions of the bubbles in structure chart according to their categories and the relative locations in data flow diagram. To make the problem into manageable size, the whole system is broken down into separate parts called activity units. A great deal of manual jobs, such as checking processes leveling, checking data derivation of processes, deriving structure chart from data flow diagram, checking any inconsistency between data flow diagram and structure chart and so forth, can be automated by using SASDL and conversion tool. The specification of structure chart derived by conversion tool may be used in an initial step of design to be refined by SASDL users.

기업은 비즈니스 프로세스 조정 또는 기업의 전략적 목적을 달성하기 위하여 정보 기술을 도입하고 있다. 또한 데이터 일관성에 대한 요구에 대해서는, 소프트웨어 개발에 적용되어 표준화 규율을 채택하여 이를 따르는 소프트웨어 개발 회사들이 늘어나고 있다. 이는 사용자들의 요구일 뿐만 아니라 이러한 규율을 채택함으로써 적은 비용으로 더 나은 결과물을 얻을 수 있기 때문이다. 프로젝트 관리 도구를 사용한 체계적이고 일관적인 소프트웨어의 개발은 더욱 더 중요한 의미를 가지게 된다. 따라서, 본 논문은 효율적인 데이터 사전관리를 통하여 효과적으로 시스템 구축 지원을 할 수 있는 프로젝트 관리 기법에 대하여 기술한다.

The Korean halibut farming industry suffer from price instability and demand decrease due to various environmental and social issues. It is urgent to predict the appropriate amount of halibut production. However, it is not easy for employments working in the halibut farming industry to handle statistical tools in order to perform the prediction. In this paper, we implemented a Excel-based regression analysis tool that allows users to get a regression analysis result by just entering historical data in a sheet. Our tool will reduce workloads of employments working in the halibut farming industry by enabling them to perform a regression analysis with Excel on-the-fly. This study expect that by using the tool the halibut farming industry cope actively with the real-time change in the industry.

DNA microarray data analysis is a new technology to investigate the expression levels of thousands of genes simultaneously. Since DNA microarray data structures are various and complicative, the data are generally stored in databases for approaching to and controlling the data effectively. But we have some difficulties to analyze and control the data when the data are stored in the several database management systems or that the data are stored to the file format. The existing analysis tools for DNA microarray data have many difficult problems by complicated instructions, and dependency on data types and operating system. In this paper, we design and implement network-based analysis tool for obtaining to useful information from DNA microarray data. When we use this tool, we can analyze effectively DNA microarray data without special knowledge and education for data types and analytical methods.

The efficient and economical use of an FMS presupposes a good capability : flexibility, reliability, maintainability and built-in quality assurance. One subsystem of an FMS, which often increases capability, is the tooling management. The main problems associated with tooling in an FMS are large variety of tools, many setups, insufficient use of presetted tools, tool condition control, tool shortages, errors in tooling data and maintainence. This paper presents a reseach on the development of a system which manages the tool data for the factory using NC turning machines. The tool information concerning each production stages of the industry is studied in the CIM(Computer Integrated Manufacturing) view point.

The KSLV-II project with high difficulties technically requires thorough technical management during long-term life cycle more than 10 years for launching into space. The TRL is a quantitative indicator developed by NASA widely used all over the world to measure technology maturity of a system development objectively and consistently. The TRL is also used to make sure technology level and to establish a future direction in the KSLV-II project. The TRL has advantage enable to identify a technology level through quantitative indicators. However, it takes a lot of efforts such as trials and errors, time and cost to apply it to the project considering the project environments, and stakeholder needs. These include not only to establish TRL management plan from ideal, conceptual and abstractive standards/guidelines such as NASA's, but also to construct TRL management environment enable to apply and manage harmoniously. In the KSLV-II project, it is required to figure out current technology level and technology development trend in the future, to access conveniently, to share related data in real time, and to update periodically for the comprehensive TRL management. From the reason above, the TRL management environment was built by using the systems engineering tool already has been used for other system management data such as requirements in the project. It also could be accomplished a practical management basis of systems engineering from the traceability among system management data including TRL. In this paper, case study results are introduced to manage the TRL for the space launch vehicle using the systems engineering tool in the KSLV-II project.

Purpose: This study was to develop an effective evaluation tool for evaluation of hypertension prevention and management program(HPMP) in community health posts (CHPs). Method: Evaluation tool composed from the literature review, the field visiting, and the in-depth interviews with the community health practitioners. Result: The evaluation tool had four domains, each with different maximum points:, hypertension prevention (35), hypertension management (40), environment of the CHPs(10), and evaluation system of the HPMP(15). The first domain was hypertension prevention with sub-domains of health education, and early detection of patients with hypertension. The second domain was hypertension management with sub-domains of management of health records of patients, education and counseling, and treatment and follow-up of patients. The third domain was the environment of the CHPs with subdomains of accessibility of CHPs to residents, accessibility of general health data to the public, and availability of health information to the public by multimedia. The fourth domain was the evaluation system of the HPMP with the subdomains of planning of program, formative evaluation, process evaluation, and summative evaluation. Conclusion: The newly developed evaluation tool will contribute not only to plan and set goals for evaluation of HPMP in CHPs.

When companies or institutes manage data, in order to utilize it as useful resources for decision-making, it is essential to offer precise and reliable data. While most small and medium-sized enterprises and public institutes have been investing a great amount of money in management and maintenance of their data systems, the investment in data management has been inadequate. When public institutions establish their data systems, inspection has been constantly carried out on the data systems in order to improve safety and effectiveness. However, their capabilities in improving the quality of data have been insufficient. This study develops an automatic tool to diagnose the quality of data in a way to diagnose the data quality condition of the inspected institute quantitatively at the stage of design and closure by inspecting the data system and proves its practicality by applying the automatic tool to inspection. As a means to diagnose the quality, this study categorizes, in the aspect of quality characteristics, the items that may be improved through diagnosis at the stage of design, the early stage of establishing the data system and the measurement items by the quality index regarding measurable data values at the stage of establishment and operation. The study presents a way of quantitative measurement regarding the data structures and data values by concretizing the measurement items by quality index in a function of the automatic tool program. Also, the practicality of the tool is proved by applying the tool in the inspection field. As a result, the areas which the institute should improve are reported objectively through a complete enumeration survey on the diagnosed items and the indicators for quality improvement are presented quantitatively by presenting the quality condition quantitatively.
