Nowadays, the importance of role of the international standardization keeps increasing substantially. We have already known that international standards have a huge impact on many companies, industries and nations. So far, it has been thought that standardizations are needed after the new products come into the market and are mass-produced in order to encourage the use of the products, systems and services. Standardization will make the products more safe, efficient, and environmentally friendly for the users. However, in these days, a paradigm of the standardization has been changed. International standard becomes a tool for dominating global market and is the most important ingredients of the competitiveness and economic progress of the nation and enterprises. Many countries like Japan, Germany and U.S. use the standardization as an effective method to dominate the market and monopolized the new technologies. Therefore, worldwide competition for the standardization of the new technology become fierce. Korea is leading the technology in semiconductor field. However, activities of international standardization are not sufficient. In order to boost the standardization activities in Korea from industry, academia, and research institute, this paper briefly introduce the international standard organization and some critical issues for next-generation semiconductor memory such as flexible semiconductor, automobile semiconductor and wearable devices.

According to the Korea Ministry of Transportation report in 2015, domestic used car trade (3.66million) is twice the number of new car sales (1.84million). However, contrary to the quantitative growth of the used car trading volume, chaotic used-car market practice has not been improved and also, space that holds these markets (facilities) has remained at a very low level of quality. Lemon Market, asymmetry of information, false bait, tout, dual contracts, negative words that qualify the used car market information are still in place. The aim of this study was to understand the unique circumstances of the used car sales market distinguished from new cars, and to analyse the problems of recent domestic used car market facilities and afterwards to draw guidelines for new used car facility architecture. Through literature review, surveys, the characteristics of domestic used car market have been organised and field research and competitive analysis of the Korea used car market architecture is followed. As a result, empirical guideline for Korea used-car market facility is introduced.

Accidents involving wheelchair accessible vehicles have been frequently occurring since the introduction of these vehicles in the Korean market. However, detailed regulations, which are required to ensure the safety of the wheel-chair occupants, are unavailable. In this study, both domestic and international vehicle safety regulations are analyzed in order to select the regulations that are similar to the transportation environment of Korea. Sled tests with an actual wheel-chair accessible vehicle were carried out based on the analyzed regulation requirements, as well as the values of the HIC, belt loads, dummy movements, and wheelchair movements. The test results showed that the movements of the dummy and the wheelchair did not meet the criteria of the regulation due to the improper positioning of the restraint systems.

Recently, in order to reduce the time required to replace an optical jumper cord, many researchers are using a field-installable connector and applying the ferrule polishing method, ferrule mechanical contact method, or ferrule fusion contact method. However, the process of arranging the length of the optical fiber, i.e., inserting the optical fiber into the ferrule by hand and checking its cross section, takes 60% of the time required for the entire process, which increases the overall cost. Therefore, in order to make this task more cost-effective, we will develop an automated inspection system with automatic cross-sectional arrangement of a field-installable connector. This system will be able to decrease the failure rate from 10% to 2% compared with the conventional method when cutting the optical fiber inserted into the ferrule. It will also improve the productivity by decreasing the test time by 28% compared with the conventional method. Our studies showed that it was possible to reduce the production costs and improve the quality of a field-installable connector, and we expect it to dominate the market.
