  • As the international trade has been increased, unified worldwide standards are getting more important and necessary. At the TBT(Agreement on Technical Barrier to Trade) of WTO(World Trade Organization) and the CTI meeting of APEC(Asia-Pacific Economic Cooperation), they made an agreement with applying International Standards to National Standards gradually. In addition, ISO (International Organization for Standardization) established the ISO/IEC Guide 21, a guideline for applying International Standards to National Standards. In these environment, Korean Industrial Standards has to be prepared for it. This paper introduce the comparison between Korean Industrial Standards and ISO Standards about the standards of sampling and testing the fresh concrete, based on ISO/IEC Guide 21 by ISO and the Applying guideline by Korean Agency for Technology and Standards, and then discuss the problem about applying them. The overall objective is to establish the applying guideline on construction fields, which is civil and building engineering part(KS F) of Korean Industrial Standards.

  • The purpose of this study is to identify in two aspects the relationship between standardization activities and technological development at the firm level. The first aspect is to analyze the relationship between the current Korean industrial standards system and the firm's technological development vis-a-vis quality standards. The analysis reveals that even if Korean firms recognize the importance of standards, the level of product quality of the KS mark is still lower compared to the average world level. The survey also reveals that the reasons for acquiring ISO and KS marks are mainly aimed at enforcing company image and increasing quality management mind, rather than to foster technological innovation. The second aspect explores how much Korean industrial standards (KS marks) affect the firm's technological development in the Process of standards acquisition activities. The survey results show that standardization activities have a less positive impact on technological innovation than on the maintenance of consistent production works.

  • Now, the possibility of Unification South and North Korea is much higher than any other times and the various fields of society, including politics, have been tried to overcome the differences between two nations. Most of all, overcoming the industrial differences for economic co-operation is one of the most important issues. About 50% of Export goods has been put in the claim in South Korea because of quality problems. And one of the important reasons is because of industrial standards. These kind of problems would be occur with economic co-operation. so the study about the standards of North Korean industries is much important before the trades is boomed. And this research would decrease the expense of unification of South and North before the difference would be larger than now. That's why the conference for industrial standards between South and North Korea should be held soon in order to overcome the differences of industrial standards. This paper not only suggested the difficulties and needs of the industrial standard unification, but also researched North Korean industrial standardization and quality inspection systems with specific examples. And this study proposed some subjects of the industrial standard unification and the present situation of standards between two nations.

  • Quality assurance with high safety profile is one of the most critical issues to medical device manufacturing. In general, this issue was not paid proper attention with respect to acupuncture needle and its related devices. Acupuncture needles are manufactured through various standards ranging from purely hand-made, partially hand-made and partially machine-made, to fully machine-made mainly in China, Korea, and Japan. There is a large difference in quality between needles from different manufacturers. In order to provide a standard manufacturing guideline, it seems necessary to make a Korean Industrial standard (KS). The authors review this topic from an historical view point, investigate the current situation of the standardization of acupuncture needles in other developed countries, and inspect the general procedure to establish a KS in Korea in order to suggest a KS for acupuncture needles.

  • User-friendly-web-based database system for searching creep property data was developed. This system includes about 38000 creep data for 270 different materials including low carbon steel, stainless steel and alloy steel. Data on creep rupture, creep deformation, creep crack growth and creeping materials can be searched through this system. Retrieved data is displayed in numeric form and also presented in graphical form for visualizing the data. Furthermore, the creep rupture data is designed to be fitted to a regression equation of logarithmic stress using time-temperature parameter(TTP). The degree of the regression equation, orthogonal polynomials, was determined using analysis of variance.

  • Since the ISO decided to deal with rare-earth elements at the $298^{th}$ Technical Committee (TC) in 2015, Korea has participated in four plenary meetings and proposed four standards as of June 2019. The status of ISO TC 298, the standards covered by the TC, and the standardization strategies of Korea are summarized. Korean delegations are actively engaged in WG2, which deals with recycling, proposing four standards for fostering the rare-earth recycling industry. However, the participation of domestic experts is still low compared with the increase in the number of working groups and the number of standards in TC 298. The aim of this article is to summarize the current status of ISO international standards related to rare-earth elements, to encourage relevant experts to participate in standardization, and to develop international standards that accurately reflect the realities of the industry.

  • A method is described for ideally reconstructing the profile from a surface profiling measurement containing a reasonable amount of null measurement data. The proposed method can conjecture lost information and rectify irregular data that result due to bad measuring environments, signal transmission noise, or instrument-induced errors, The method adopts the concept of computer graphics and consists of several processing steps. First, a search for valid data in the neighborhood of the null data is performed. The valid data are then grouped and their contours are extracted. By analyzing these contours, a bounding box can be obtained and the general distribution of the entire area encompassing the valid and null data is determined Finally, an ideal surface model is overlaid onto the measurement results based on the bounding box, generating a complete reconstruction of the calculations, A surface-profiling task on a liquid crystal display photo spacer is used to verify the proposed method. The results are compared to those obtained through the use of a scanning electron microscope to demonstrate the accuracy of the proposed method.
