Quality has been a key issue to manufacturers. Many distinguished scholars have defined quality with profound insight. Korean firms struggle to make better products to fulfil requirements and satisfy customers. Korean industries have implemented quality management from Japan in early 70s. Statistical quality control, QCC (Quality Control Circle), and total quality management have also been introduced in succession. Chief executive officers, managers, and field employees have been aware of the importance of quality since then. This quality movement force workers to improve quality. They have to maintain the quality of products and compete with foreign products. Korean industries were able to compete with foreign industries in price. However, Korean firms now have to compete in quality as well as price. ISO (International Organization for Standardization) was established and industries around world have started to implement standardized systems depending on their need. ISO 9000 has continuously been revised and firms around world started to register a ISO 9000 certificate. Today's quality competitiveness gets more deeply involved. KSA (Korean Standard Association) have launched QCAS (Quality Competitiveness Assessment System) since 1997. Up until now recent status of QCAS have been reported but the characteristics of QCAS results have not been analyzed. In this article we examine the QCAS results of 41 firms in 2014. QCAS consisted of 13 subsections : strategy and management system, organization culture and development of human resource, information management, quality system, customer satisfaction, management achievement, TPM, logistics, product development and technology, PL, QCC, SQC/SPC, and reliability. We performed one way ANOVA to discover the difference among the levels of firm size, business type, and quality hall of fame using the total scores of 13 subsections resulted from QCAS. We also analyzed the scores of 13 individual subsections of QCAS to see if there is any differences based on firm size and business type. We interpret the results and implication of analysis and finally draw a conclusion.

Architects and designers of the 20th Century made various efforts to establish new design languages reflecting the changes of society, the times, and environment. They used furniture, especially chairs, as controversial items of aesthetic value, society and ideology. Le Corbusier and Alvar Aalto are furniture designers as well as architects, who adopted this ‘spirit of the times’ actively and have greatly contributed to modernism. This study will help us to understand the diversity of design since modernism, by comparing these two designers' furniture design. It also covers the common factors In modern furniture design, and analyses their individuality and likeness In design. The following is a comparison of furniture design by Le Corbusier and Alvar Aalto. Le Courbusier linked International design and Aalto linked Rational design and Organic concept design to their furniture, just as they did in their architecture. They were able to establish the base of modern furniture design by adapting new concepts and pursuing humanism. In structure, Le Corbusier's furniture Is simple and proportional. It demonstrates a sophisticated geometric composition, mechanical beauty. On the other hand, Aalto rationally linked nature with human requirements and his furniture is organic and in harmony with geometric structure. In function, Le Corbusier's furniture is standardized and prefabricated. He designed for the user so they could choose to use the furniture efficiently to suit their needs. In comparison with Le Corbusier, Aalto Invented the ‘Stacking Chair’ which allows a more effective use of space and reflected the structure of the human body to improve the user's comfort. In materials and techniques, Le Corbusier used new materials like metal or leather, and attempted new ways such as welding, prefabrication, and standardization for production. On the contrary, Alto mainly used birch, which is the traditional material in Finland, and tried new bent wood techniques and joining methods.

R&D Personnel information is constructed locally based on the needs of each institute and therefore is distributed over different databases. It does not support inter operability which makes it difficult to access and update that leads to the problem of ineffective usage. In this study, we have categorized the lower level information that forms the domestic S&T Personnel and defined the relationship between each type of information to suggest a standard for the data elements that guarantee the access to specific information in order to support inter operability. We have analyzed the human resource information database of domestic and foreign research institutes for the data modeling. We have also made reference to the standard metadata and database of other types that can be linked with the human resource information in designing the data elements. ISO/IEC 11179, the international standard for the metadata registry(MDR), was adopted to apply the object, attribute and expression to be described to the name of the data element.

In the recent mobile communication systems, the performance of Turbo Code using the error correction coding depends on the interleaver influencing the free distance determination and the recursive decoding algorithms that is executed in the turbo decoder. However, performance depends on the interleaver depth that need a large time delay over the reception process. Moreover, Turbo Code has been known as the robust ending method with the confidence over the fading channel. The International Telecommunication Union(ITU) has recently adopted as the standardization of the channel coding over the third generation mobile communications such as IMT-2000. Therefore, in this paper, we proposed of the method to improve the conventional performance with the parallel concatenated 4-New Turbo Decoder using MAP a1gorithm in spite of complexity increasement. In the real-time video and video service over the third generation mobile communications, the performance of the proposed method was analyzed by the reduced decoding delay using the variable decoding method by computer simulation over AWGN and fading channels.

In this paper, we propose a novel hardware architecture to facilitate the applicable SoC chip design of H.264/SVC which has a great deal of advancement in the international standardization in recent. Moreover, a new C-model simulator based on the proposed hardware system will be presented to support optimal SoC circuit development. Since the proposed SVC decoder is consist of some hardware engine for processing of major decoding tools and core processor for software processing, the system is simply implemented with the conventional embedded system. To improve the feasibility and applicability, and reduce the decoder complexity, the hardware decoder architecture is constructed with only the consideration of IPPP structure scalability without using the full B-picture. Finally, we present results of decoder hardware implementation and decoded picture to show the effectiveness of the proposed hardware architecture and C-model simulator.

In the midst of a continued discourse and development concerning design education and its impact on innovation and creativity, I believe that design education still holds the key to enhancing design methodology while increasing creativity by having students take on several creative roles in an interactive and enjoyable studio course. Clearly, there exist impediments that block the creative process in our standard track in design education; however, a course entitled "The Creative Workshop" can overcome such obstacles. Through this course, a student can learn the essential skills of a designer: inventive thinking, a sense of aesthetics, and a spirit of collaboration. In addressing each of the three essential elements, this course has devised role-plays in the way of projects. Simply put, students will be required to demonstrate and, therefore, express their unique creativity that may have otherwise gone muted. Such creative expression can take form in a low stakes, open forum that heralds the invaluable attribute in design such as creative freedom. As a result, the true spirit of creativity is fostered rather than mere aesthetics and styling. Moreover, through role plays, the focus shifts its center from design, allowing each student to explore the uncharted areas of one's own creativity which may come naturally to some extend while disconcerting to others. It may prove particularly uncomfortable for Korean students whose ideas about education have been directly connected to the strict and regimented school system that stresses adherence to standardization such as the national college entrance exam. This course, therefore, is aimed stretch the scope and scale of students' creativity as they learn to collaborate on role plays, utilizing diverse skills from various disciplines.

This study aims to summarize recent discussions on naming the sea between Korea and Japan and to draw some research topics of the geographical toponymy. The International Hydrographic Conference and the United Nations Conference on the Standardization of Geographical Names held in 2012 repeatedly saw clearly different positions of Korea and Japan on the naming of the sea. From the debates, four topics appeared distinctly which deserve receiving continuous interests in the field of geographical toponymy. These include: necessity of dual naming and characteristics of, and perceptions on the object of dual naming; political economic nature of the sea, e.g. semi-enclosed sea, EEZ, and relevant use of names; relationship between the sea containing strong emotional ties and its naming; additional definition of toponymic terminologies to proceed with more objective and logical discussions.

Purpose: The objective of this paper was to compare test standards regarding the performance and safety of agricultural tractors to identify the differences in test conditions, measurement tolerances, and test procedures. Based on the comparison, some recommendations were proposed for possible revisions or improvements to current tractor test standards. Methods: The test standards and codes of major standards development organizations (SDOs), such as the Organization for Economic Cooperation and Development (OECD), the International Organization for Standardization (ISO), the American Society of Agricultural and Biological Engineers (ASABE), EC type approval, and the board of actions of the Nebraska Tractor Test Laboratories (NTTL), were selected and analyzed. Comparison of the test standards: The ISO provides references for fuel and lubricants for tractor tests, and the OECD provides additional measurements for calculating fuel consumption characteristics during the power take-off (PTO) tests. The ISO, EC type approval, and the ASABE provide PTO protective device and the safety requirements. During drawbar power tests, seven transmission ratios are selected for fully automatic transmissions, according to the OECD. In case of hydraulic lift tests, ISO 789-2 and OECD Code 2 advise the use of a static lift force, while SAE J283 advises the use of additional dynamic lift capacity tests for a better representation of in-field operations. The OECD, the ISO, and EC type approval determine the seat index point (SIP), whereas the ASABE determines the seat reference point (SRP) for roll-over protective structure (ROPS) tests. Diversified measurement tolerances were among the braking performance test standards. The European Union (EU) has developed daily limits for vibration exposures with adaptations from ISO 2631-1. Electromagnetic compatibility evaluations are emerging of high-efficiency tractors due to the long-term conformance to electromagnetic emissions and interferences. Comparisons of tractor test standards discussed in this paper are expected to provide useful information for tractor manufacturers and standards development personnel to improve the performance and safety test standards of tractors.
