The purpose of this articls is to investigate the impacts of ISO 14001 certification on the compliance of environmental regulations by Korean companies. The impact of ISO 14001 certification on the industries obtained the certificates was studied through a survey with questionnaires, and the compliance of environmental regulations was investigated using governmental release data. Motivations of Korean companies' environmental management were mostly caused by customer's request and the requirement from foreign countries. Certified enterprises showed more 3 times compliance of environmental regulation than non-certified ones. Such results were accomplished by systematic environmental management such as clear implementation purpose and all employee's voluntary improving according to ISO 14001 requirement. The continuous monitoring system was possible through internal audit and biannual audit from the certification body, to be finally verified by the top management. The four steps in ISO 14001 environmental management system, which are objective, methodology, inspection and monitoring, has contributed to this achievement.

As memory-extended RFID tags are recently developed, various types of item identification structures can be stored in the tags. In this paper, we propose a new national product identifier(NPI) which accepts not only ISO item identification standards but also the memory capacity of ISO tags. First of all, item identification structures of ISO/IEC 15459 and EPC, and memory structures of ISO/IEC 18000-6C and EPC tags are analyzed. Based on these analyses, the NPI currently used is analyzed and its problems are described from the viewpoint of standardization. To overcome the problems, a new NPI structure suitable for ISO/IEC 15459 is proposed. Finally, data related to the NPI is designed for encoding to tags.

This study set out to developing data exchange standard between roadside device and traffic information center fitted in a domestic environment by applying international standard ISO 15784. First, we defined message basic concept of 'Dialog' and essential elements should be defined to define the standard message for securing system compatibility by reference ISO 14817 and ISO 14827 Part 1. For defining standard message items exchanged between AVI and traffic information center, we formed Working Group under ITS Standards Technical Committee and analyzed data flow for ITS National Architecture, Standard messages of existing standards, and AVI operation messages actually operated on roadside now. So, we extracted 14 functionally needed messages and defined 28 standard messages adopting 'Dialog' concept. In case of the application protocol for data exchange standards, we defined basic requirements for securing interoperability and interchangeability considering domestic environment by analyzing reference standard of ISO 15784.

In this paper, Air-interface protocols of ISO 18000-6 Type A and B applied to RFID system in UHF band are analyzed, and those algorithms are realized. Also, the improved anticollision algorithms for the Type A and B of ISO 18000-6 protocol are proposed and the performances are compared. As the results, reduction ratio of total tag recognition time of the improved ISO 18000-6 Type A algorithm is 35.2 % for 100 tags and 24.3% for 1000 tags with respect to standard algorithm, respectively. And the reduction ratio of the improved ISO 18000-6 Type B algorithm is 6.0% for 100 tags and 6.6% for 1000 tags. Therefore, the improved anticollision algorithm proposed in this paper is the advanced method improving the performance of tag recognition in the RFID system.

In spite of the prescriptions on the reference X-ray fields given by the International Organization of Strandard(ISO) and American National Standard Institute(ANSI), the measurement of X-ray spectrum is not only time consuming but very difficult, paticularly when significant corrections have to be applied to the measured pulse-height distributions of the observed spectra. This paper describes the calculation method of ISO Narrow Series and ANSI X-ray filtered radiations by theoretical model which is modified framer's theory by target attenuation and backscatter correction. The X-ray spectra, average energies and conversion coefficients are calculated and compared with those obtained using the spectra prescribed by ISO and AMSI to assure good agreement.

ISO 9001 Quality Management Systems-Requirements has been revised in 2015. It has been updated four times since its publication in 1987. It is the most widely used International Standard in the world. There are over one million companies and organizations in over 170 countries certified to ISO 9001 from an ISO survey. Organizations are supposed to be certified to this new version by late 2018. The key changes in ISO 9001:2015 are to establish a High Level Structure (HLS) and focus on Risk-Based Thinking (RBT). Risk-Based Thinking means the process approach to decide how risk is addressed in establishing the processes to improve process outputs and prevent undesirable results. It pursues process planning and controls based on risks so that organizations can improve the effectiveness of the quality management system. It maintains and manages a Quality Management System that inherently addresses risks and meets objectives. In this article we firstly attempt to explain how to understand the fundamental concept of Risk-Based Thinking which is a systematic approach to consider risks rather than treating prevention as a separate component of a Quality Management System. We comment on the detailed requirements that contain risks in ISO 9001:2015 clauses. We also summarize recent advances on the risk assessment and management in line with ISO 31000:2009 Risk Management-Principles and Guidelines. We finally propose the practical risk management procedures for implementing ISO 9001:2015 with an emphasis on RBT. This article would contribute to help quality managers and practitioners convert to ISO 9001:2015.

ISO 9001, quality management system, is widely known as advancing internal efficiency and productivity in various industry. As a result, the number of companies that have adopted ISO 9001's certification have been increasing continuously year by year since ISO 9000' family standard was published in 1987s. This fact shows that a lot of businesses are trying to get the accreditation for improving the competitiveness of quality. The purpose of this study is to present that ISO 9001's certification motives affect to the requirement's implementation and show that the execution of requirements influences on management performance in the small manufacturer. In order to carry out this research, we obtained 96 survey sheets and inspected twenty assumptions based on the reliability, validity of the questionnaires. The results of regression analysis are summarized as follows; First, the factors of certification motive influence on the requirement's implementation except resources management. Second, the two elements of ISO 9001 requirement, resources management and product realization, have an important effect on the operational performance and financial performance considerably in the companies that choose the internal motive. Finally, the two requisites of ISO 9001 requirement, resources management and measurement, analysis and improvement, affect to the operational performance and financial performance significantly in the businesses that select the external motive. Based on the results, the companies that choose the internal motive have a good performance to execute the ISO 9001 requirements. Also, to implement the requirements of ISO 9001 is helpful for the companies to produce the operational and financial performance.

The International Organization for Standardization (ISO) published ISO 9001 Quality Management System (QMS)-Requirements in 1987 and has revised four times since then. ISO 9001:2015 is the latest edition. This latest edition has two most noticeable changes. The first major change of new edition focuses on performance with an emphasis on Risk-Based Thinking (RBT) to enhance the process approach. The new edition consists of ten clauses whose first three clauses are largely same as older edition but risks are clearly stated and stressed in last seven clauses, emphasizing on Plan-Do-Check-Act cycle at all levels in the organization. The second major change is that the new edition has the same overall structure as other ISO management system standards known as High Level Structure (HLS) with Annex SL. The companies obtained the certificate of new ISO 9001:2015 QMS by September 15, 2018 in order to maintain as an ISO QMS registered firm. In this article we collected transition audit data from more than 100 companies that registered ISO 9001:2015 QMS for recent three years. We performed a statistical analysis to disclose the relationships between the characteristics of companies and the minor nonconformities found in ISO 9001:2015 requirements during transition audit processes. We also aim to interpret the findings and deduce the implications of the statistical results.
