  • Purpose: The aim of this study is to examine various national standards and to suggest problems and improvements on KS (Korean Industrial Standards) in spectacle frames. Methods: We surveyed the latest published KS, ISO (International Organization for Standardization), JIS (Japanese Industrial Standards), DIN (Deutsches Institut fur Normung) and ANSI (American National Standards Institute) standards with relating spectacle frames. The titles that were considered in comparative study were terms and vocabulary, measuring system and terminology, marking, requirements and test methods, formers, screw threads, and others. Results: There were 9 different languages such as English (USA and UK), French, Russian, Japanese, Chinese, German, Italian and Spanish for the lists of equivalent terms and vocabulary in all standards except KS and ANSI, but gave an explanation for terms and vocabulary in only KS. Complementary terms and definitions were not existed in annex of KS and ANSI for measuring system and terminology, but they were included in annex of standards of the others. KS and ANSI standard for requirements and test methods differed from the ISO revision. Except JIS and ANSI, standards of formers were almost identical. KS standard of screw threads were similar to JIS. Standards of welded joints and nickel release did not exist in KS. Conclusions: All standards except ANSI tend to follow ISO, especially DIN is almost entirely identical to ISO. But KS is behind the times because it has been amended lately or established in accordance with older editions of ISO. Therefore, in order to assist quality control and safety for spectacle frames, KS standards shall be superseded by the specifications which is identical to ISO within a reasonable time.

  • 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.

  • Although various laws and regulations have been put in place to prevent slips and falls, many accidents still occur. In this study, the root cause of slips and falls not decreasing were investigated. There are five types of slip resistance test methods in the Korean Industrial Standards (KS). Namely, KS F 2375:2016, KS F 2601:2020, KS F 2602:2016, KS L 1001:2020, and KS G 5821-1:2020 are listed. These test methods are cited in building certification standards (BF and G-SEED), construction specifications, and other documents that specify slip safety criteria. As a result of the investigation, a number of errors in KS regulations and legal text, errors in the manufacture and operation of slip testers, and errors in the use of measured values were found. These errors threaten the public life safety and disrupt industrial sites, and must be corrected immediately.

  • 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.

  • We developed the logical methods to analyze economic impacts of standardization and cleared up effects of performing KS in micro and macro aspects. This study is performed through analysing foreign studies and results from surveys. The advanced methods performing standardization as a form of 'Korean industrial standards' are suggested here, which are based on results of this study. The major consequences of this study are followings. The micro economic impact is that each company gets 604.5 millions won a year through performing KS A and F(discount rate 4.5%) and 1.46 trillions won is the macro economic impact through performing total KS A and F, which comes to 0.245% of GDP.

  • The standard is a nation's one of the most important industrial issues that improve the social and economic efficiency and also the basis of the industrial development and trade liberalization. This research analyzes the enactment and the utilization of Korean industrial standards(KS) of various industries. This paper examines Korean industries' KS utilization status based on the KS possession, enactments and inquiry records. First, we implement multidimensional scaling method to visualize and group the KS possession records and the nation's institutional issues. We develop several hypothesis to find the decision factors of how each group's KS possession status impacts on the standard enactment activities of similar industry sectors, and analyzes the data by implementing regression analysis. The results show that the capital intensity, R&D activities and sales revenues affect standardization activities. It suggests that the government should encourage companies with high capital intensity, sales revenues to lead the industry's standard activities, and link the policies with the industry's standard and patent related activities from R&D. Second, we analyze the impacts of each KS data's inquiry records, the year of enactments, the form and the industrial segment on the utilization status by implementing statistical analysis and decision tree method. The results show that the enactment year has significant impact on the KS utilization status and some KSs of specific form and industrial segment have high utilization records despite of short enactment history. Our study suggests that government should make policies to utilize the low-utilized KSs and also consider the utilization of standards during the enactment processes.

  • This study was designed to survey misused expression in 37 KS (Korean Industrial standards) related to personal protective equipment. The results were as follows: 1. One hundred and twenty five misused expressions were found - 44 expressions were used illogically (35.2 %). 80 expressions were wrongly described (64.0 %) The types of illogically misused are: 10 illogical cases, 4 cases of a wrongly designated provision when cited, 12 cases of the lack of provisons for KS, 7 cases of a inappropriate uses of units, 8 cases of an overlapped sizes between standards. - The types of expressions wrongly described are: 30 cases of confusion in using an terms, 4 case of making an error when proofreading, and 29 cases of choosing words not appropriate to describe technical standard, 18 cases of unclear provisons due to missing phrases and terms, and 11 cases of provisons described differently from original intended purposes. 2. There is one case, where the same standard is categorized as two different names. There are three major causes of the misused expressions as seen from the following summary: - Imitated the developed countries' standards without filtering them by considering domestic law and ocher KS standards. - Tended to create each definition for each standard instead use of the basic standard. - Insufficiency of synthetic examination to the correlation between standards.

  • Based on the survey for munitions companies, we have tried to find current state of the application of Korean military specifications(KDS) and their references for munition products, and how they can be improved for a better management system. On average, Korean munitions companies have 660 of KS, 18 of U.S. military specifications, and 5 of foreign standards, and annually spend about 0.4 million won for KS, but 1.3 million won for foreign standards. In addition, they have emphasized the necessity of the integrated management system for KDS and the related drawings.
