Organizations worldwide have implemented quality management system, ISO 9001:2000 and environmental management system, ISO 14001:2004. Researches have been conducted regarding occupational health and safety management system, integration of these management systems, and extension to corporate social responsibility and sustain ability management system, ISO 26000. This paper examines quality and environment management systems for machinery and metal companies using audit results. We perform statistical tests to see if there are any significant differences of minor nonconformities for requirements of ISO 9001:2000 and ISO 14001:2004 based on implementation motive, operating periods, and organization's size. We also present causes and reasons for statistical differences and minor nonconformities to use as references for implementing efficiently quality management system and environment management system.

서술 지향적인 방법에 의한 요구사항의 도출은 명확한 요구사항을 정의하는 데 있어서 불충한 것으로 지적되곤 한다. 이것은 요구사항을 기술하는 작업자들이 시스템을 이해하는 관점에 차이가 있기도 하지만, 내용의 표현방법이나 다루는 내용의 깊이, 그리고 이러한 내용을 문서화하는 방법에 있어서도 큰 차이를 갖기 때문이다. 본 연구는 이와 같이 서술적인 방법으로 도출된 GOLORY(GLObal Resource management sYstem)의 요구사항을 개선하기 위하여 UML 기반의 다이어그램을 이용한 요구사항 분석기법을 적용한 사례이다. 특히 다이어그래밍 기법을 활용함으로써 요구사항을 체계적으로 명확하게 도식화 하고, 이를 통해 요구사항의 일관성 유지와 아울러, 중요한 요구사항의 누락 방지 등의 성과를 달성할 수 있었다.

Open architecture controller (OAC) is well known technology in factory automation. To better understand the requirements of OAC, authors have discussed the OAC related topics with a number of control experts who represents different segments of the machining industry. There is no common concept that is accepted or used, however, the common ideas for OAC is the control system that is hardware independent, interchangeable, and easily scalable. This paper presents summary of the understaning and requirements of OAC. Based on the requirements of OAC, authors developed the software based PC-CNC. The main focus of the PC-CNC was on the user customization capability and open interface between control networks in manufacturing system. This paper introduces the developed PC-CNC briefly. In addition to introduction of the PC-CNC, to fill the gap between end users and vendors of OAC, this paper presents two applications using OAC. One is a remote monitoring system. The OPC (Ole for Process Control) standard interface was used to monitor the status of open architecture CNC across network. The other is the remote production management module for machine tools using standard database interface.

E-books have been popular and common in everyday life during past a decade, and the market is expected to grow much more because of the popularity of tablet computing devices such as iPad. With the helps from the devices, people want to read or experience more interactive, fun, and informative e-book contents. In order to meet those needs, we introduce requirements of an e-book viewer system that supports user interaction, 3D modeling view, and augmented reality. We also introduce some design issues of the system and its concept proof prototype system. We determine to adopt HTML5 for e-book content format because it already supports content rendering, multimedia, and user interaction. Furthermore, it is easy to implement e-book viewer because there is already Webkit component for HTML5. We also discuss design issues for integrating an Augmented Reality viewer with Webkit-based e-book viewer. This paper will give e-book viewer developers and contents developers some guidelines for new e-book systems.

Environments surrounding production sites have changed greatly in recent years. Accommodating environmental changes calls for the design and development of information systems that center on production lines. There is a need for a training program that teaches learners to understand the particulars of an operation and apply that knowledge to an information system. In this research, we used material requirements planning (MRP) as the subject for which basic skills are to be taught and developed an MRP exercise-based training program. The program is designed for 13 lectures of 90 minutes each, and it consists of MRP exercises, modeling methods to represent them, the use of a programming language for system development, and finally, evaluation of the exercises. Lecture materials are described in 505 lecture slides using Microsoft PowerPoint to allow visualization of topics through graphs and models. The developed training program was then delivered to 86 college students, and its results were measured through quizzes to verify educational effectiveness.

Purpose: This study is to analyze the purchasing process and distribution management requirements for teaching materials that have important meaning in the practical field of preschool education. Research design, data and methodology: A structured questionnaire was used to survey 103 childcare staffs regarding the purchasing process and distribution managements. The collected data underwent Likert's 5-point scale analysis and keyword grouping. Additionally, ANOVA was conducted to examine the distribution management demands based on demographic characteristics. Results: The purchasing of teaching materials involved more offline channels than online, and the purchase decisions were predominantly made by principals rather than teachers. Although the purchasing process is similar to that of general businesses, there are difficulties in purchasing due to the disorganized distribution channels and limited accessibility to product information. Additionally, the management of inventory for teaching materials is challenging due to limited personnel and storage. Childcare staffs have requirements for classification systems, evaluation criteria, environments and policies related to teaching materials distribution. The need to introduce a teaching material evaluation and certification system to ensure quality was not high. Conclusions: Most of the respondents recognized that strict management and measures should be taken for the distribution of teaching materials. There were differences in the demand of teaching material distribution depending on the respondents' status, age, education, and experience.
