  • Purpose: This paper studied about the integration for management system of representative international standard related to sustainable development. The well-known International standards such as ISO 9001, ISO 14001 and OHSAS 18001 (ISO 45001) can be operated in accordance with the organizational situation individually, or in a variety of ways of integration. It can be applied to help organizations utilizing the newly established "ISO IEC Directive Part1 Annex SL", when integrating quality, environmental and safety & health management systems based on international standards. Methods: We conducted an empirical survey of management executives and experts to study how three factors (management systems, organizational capabilities and integration methods) could affect business performance. Results: The questionnaire was analyzed using AMOS structural equation model. Quality, environmental and safety and health management systems affected management performance, and integration methods of management system affected business efficiency, risk performance and financial performance. Integration method is also important because organizational competence affects various aspects of integrated management. However, factors that affect integration should also be considered in terms of organizational capabilities. This is because organizational capacity influences the integration plan. Conclusion: To integrate the document system at the strategic level, management should actively participate in integrated operations to integrate organizations, eliminate duplicate tasks, and foster document integration experts to reflect the characteristics of individual standard. In the case of document integration, quality management is focusing, but once ISO 45001 is issued, the use of Annex SL is increasing, and Quality, environment and safety & health integration will also be expanded. It is possible to increase the effect of integration by strategically approaching and establishing organization document system rather than simple integration according to management system standard arrangement.

  • CDISC (Clinical Data Interchanging Standards Consortium) standards are to support the acquisition, exchange, submission and archival of clinical trial and research data. SDTM (Study Data Tabulation Model) for Case Report Forms (CRFs) was recommended for U.S. Food and Drug Administration (FDA) regulatory submissions since 2004. Although the SDTM Implementation Guide gives a standardized and predefined collection of submission metadata 'domains' containing extensive variable collections, transforming CRFs to SDTM files for FDA submission is still a very hard and time-consuming task. For addressing this issue, we developed metadata based SDTM mapping rules. Using these mapping rules, we also developed a semi-automatic tool, named CDISC Transformer, for transforming clinical trial data to CDISC standard compliant data. The performance of CDISC Transformer with or without MDR support was evaluated using CDISC blank CRF as the 'gold standard'. Both MDR and user inquiry-supported transformation substantially improved the accuracy of our transformation rules. CDISC Transformer will greatly reduce the workloads and enhance standardized data entry and integration for clinical trial and research in various healthcare domains.

  • As the application area of software grows bigger and the importance of software quality increases, software quality evaluation method is also getting a lot of attention. To evaluate the software quality properly, we need an objective and concrete evaluation mechanism. In general, practitioners customize the international standards to their own needs for this purpose. Package software documents plat an important role in software quality evaluation because it provides the information that helps customers use the software effectively and conveniently. h great deal of efforts has been made in terms of international standards for documentation and documentation process. However, those international standards are too abstract to be applied directly to domestic software packages. In this paper, we developed a guidelines and checklists for writing and evaluating package software documents. Our research basically followed ISO 12119, ISO 9127 and some related research results. Also we proved the effectiveness of this research through actual tests with package softwares.

  • The installation of lightning protection system has recently been increasing, but the amount of damage has still been increasing. In this study, survey (interview) and field conditions were conducted to identify the installation and safety standards of the lightning protection system. it was analyzed that the safety management system is non-existent at the stage of the design, manufacturing and construction of the site lightning protection system, and that the safety inspection of the lightning protection facility is not properly managed. It has been shown that lightning protection systems, that can solve these problems, need to be re-established according to the reality so that safety inspection can be carried out in accordance with safety standards such as management of safety certification products, operation of survey institutions, design, manufacturing, and construction of safety standards at a national level.

  • This paper presents an IHQRR (Integrated High Quality Rectifier Regulator) BIFRED (Boost Integrated Flyback Rectifier Energy Storage DC-DC) converter fed BLDC (Brushless DC) motor drive. A reduced sensor topology is derived by utilizing a BIFRED converter to operate in a dual DCM (Discontinuous Conduction Mode) thus utilizing a voltage follower approach for the PFC (Power Factor Correction) and voltage control. A new approach for speed control is proposed using a single voltage sensor. The speed of the BLDC motor drive is controlled by varying the DC link voltage of the front end converter. Moreover, fundamental frequency switching of the VSI's (Voltage Source Inverter) switches is used for the electronic commutation of the BLDC motor which reduces the switching losses in the VSI. The proposed drive is designed for a wide range of speed control with an improved power quality at the AC mains which falls within the recommended limits imposed by international power quality standards such as IEC 61000-3-2.

  • Researches and developments of tidal energy converters are close to commercialization stage. But, commercialization of tidal energy converters is not ready in korea. In Europe, many experts of company, laboratory and public institution involved in marine energy are active for commercialization of marine energy converters in European Marine Energy Centre. Furthermore, in IEC/TC114, standardization of technical standards for assessment and certification of tidal energy converters of each country is under discussion. Therefore, We have to prepare for commercialization, standardization and entry into the overseas market. In this study, trends of commercialization and standardization of international markets of marine energy converters are investigated and certification schemes of overseas are analyzed. We expect that this study will make contribution to establish the foundation of commercialization of tidal energy converters.

  • A first step review is completed on the suitability of European designed wind turbines in an East Asia climate. Six parameters are chosen for detailed analysis of proper meteorological measures from flat, hilly, forested, coastal and offshore sites in West Europe and East Asia: mean wind speed, 10 minute mean wind speed distribution, turbulence intensity, wind shear, 3 second extreme wind speed and 10 minute direction change. All six parameters are assessed with a view for contrast with the wind turbine design standard IEC61400. The diurnal and seasonal variation, average and extreme values of each parameter are calculated where appropriate. Industry standard software and analysis techniques have been employed to assess the applicability of existing wind turbine design standards and design guidelines for the East Asian market.

  • With the rapid change in today's R&D environment and the enlargement of the expected quality level for R&D outcomes, it has become increasingly necessary to effectively define the R&D standard processes tailored for our organization and projects. To meet this needs, we defined the R&D standard processes based on the standards for systems and software engineering and our traditional work methods and applied them to our ongoing projects. We will improve our defined R&D standard processes continuously by monitoring of the processes and the feedback of the application results. In this paper, we introduce the R&D standard processes developed by E Research Institute and the requirements and approaches used for their development. We compare our defined R&D standard processes with ISO/IEC 15288 which is the first international standard for systems engineering.
