  • The field application through the quality control of self adhesive rubberized asphalt waterproofing sheet was regulated by KS F 4934 of Korea Standard in 2003. However, the regulations that the different material properties of self-Adhesive waterproofing sheets are difficult to quality control on the standard. Therefore, this research was performed for of quality control all affiliations of self-adhesive waterproofing sheet through basic properties test and proposed quality standard revised bill in KS F 4934.

  • This study aims to review the standard operation status on wood, pulp and paper industry in Korea according to the industry standardization law which has been revised for strengthening expertise of relevant department and to propose a management strategy of Korean Standards (KS) in figure. Korea Forest Service (KFS) is the responsible department of managing KS on the wood, pulp and paper industry from 2015, and currently opertates three expert committees (wood and wooden construction, wood-based materials, pulp and paper) and wood and paper industry council to review 426 standards. To support an improvement of technical competency and securement of marketability of Korean wood industry, it is about time to review the standards and to develop practical standards since it is managed by specialized department. For this purpose, it is necessary to establish a systematic approach on the management of KS, based on thorough analysis of current KS. To remove possible technical barrier on trade due to the differences of standards between countries, the conformity with international standards is necessary. Also, for sustainability of standard management system, training specialists and building their capability is essential.

  • This study is a part of the serial studies on the historical developments of cataloging rules in Korea and focuses on the rules related with KORMARC. As for KORMARC formats, the experimental format based on LCMARC and UKMARC was developed in 1980, after that, KORMARC Pyojunyong Format for monographs in 1981, KORMARC Pyojun Format for monographs in 1984. At last KORMARC KS Format for monographs has been published in 1993 after discussing carefully the revised scheme of KORMARC format by the Korean Society for Information Management. The pre-note edition of KORMARC Description Rules for monographs, based on ISBD, was published in 1983, the revised pre-note edition in 1985, and at last A study on KORMARC Description Rules for Monographs by the Korean Society for Information Management in 1991.

  • Only ground source heat pump units certified according to the regulations in Korea can be adopted in ground source heat pump systems. In this study, domestic and international standards and regulations for ground source heat pump units were investigated. Unlike ISO 13256-1~2, which is the international standard, KS B 8292~8294 for ground source heat pump unit only included rated test conditions. Therefore, it is necessary to supplement various test conditions to the KS B series, because its performance data, which is required to calculate the system's design capacity, is dependent on the change in entering water temperature. The difference between the coefficient of performance of the certified ground source heat pump units and the certified criteria changed significantly according to the operating mode, heat source, and load type, because the criteria increased by about 5% for all. Thus, it is highly suggested that the certification standards be revised while considering the product performance level and various conditions.

  • In hopes of resolving the issue of poor quality of information input for teaching spoken English online, the study creates an English teaching assistance model based on a recognition algorithm named dynamic time warping (DTW) and relies on automated voice recognition technology. In hopes of improving the algorithm's efficiency, the study modifies the speech signal's time-domain properties during the pre-processing stage and enhances the algorithm's performance in terms of computational effort and storage space. Finally, a simulation experiment is employed to evaluate the model application's efficacy. The study's revised DTW model, which achieves recognition rates of above 95% for all phonetic symbols and tops the list for cloudy consonant recognition with rates of 98.5%, 98.8%, and 98.7% throughout the three tests, respectively, is demonstrated by the study's findings. The enhanced model for DTW voice recognition also presents higher efficiency and requires less time for training and testing. The DTW model's KS value, which is the highest among the models analyzed in the KS value analysis, is 0.63. Among the comparative models, the model also presents the lowest curve position for both test functions. This shows that the upgraded DTW model features superior voice recognition capabilities, which could significantly improve online English education and lead to better teaching outcomes.

  • This study aimed to focus on the optimization of the external dimension sizes in the corrugated fiberboard cartons (CFCs) for exporting agricultural products. The commercial CFCs of current fresh produces such as paprika, Asian pear, melon, sweet potato, and oriental melon for export were used for this study. The guidelines of the minimum internal dimensions of the refrigerated reefer container, the dimensions of pallets, and the maximum load height of a stack were referred to KS T ISO 668, KS T 1372, and the Container Handbook by the German Insurance Association, respectively. These principles were selected as a ground rule for the external dimensions of CFCs. Package layout design programs of ArtiosCAD and Cape Pack software were used to confirm the box stacking patterns and revise the external dimension of CFCs. The final external dimensions of each CFC were revised from 5 to 30 mm compared to its original dimensions. The maximum load of each stacking box per pallet has been increased from 0.0 to 12.5% compared to its original load.

  • The performance evaluation of cold weather clothing is mainly carried out with thermal resistance. However, the results of the revised test method regarding the same specimen were decreased compare to previous one. In addition, there were deviations of the results among the authorized testing institutes according to the different interpretation of the KS test method. This makes it a considerable difficulty to the quality assurance of combat supplies. The purpose of this study is to minimize the variation of the results before and after the revision by analyzing the cause of the decrease in the heat insulation rate according to the revised test method. For this purpose, the difference between the test conditions before and after the revision of KS is analyzed and the possible results are reviewed. In addition, we want to minimize the result deviation between testing laboratories by analyzing the cause of the result deviation between test laboratories according to arbitrary interpretation of the standard. Based on this, we propose a standardized test method to prevent the decrease of the heat insulation rate by checking the pre-revision test method and the condition with the least deviation.
