  • Purpose: The diverse users and the increase of power wheelchair users have made it difficult to apply the standards of Wheelchair user accessible toilet rooms for the existing law and BF-certification. To address these issues, the standards of the relevant laws have been improved (Ministry of Health and Welfare, 2018), but there are still many problems. In this study, problems with the standards for Wheelchair user accessible toilet rooms in Korea are analyzed by comparing national and international standards. In addition, improvements to standards for Wheelchair user accessible toilet rooms will be suggested. Method: It presents improvement for standards of Wheelchair user accessible toilet rooms by comparing national, international standard and standards of many countries. Korean standard, International Standard(ISO 21542), American Standard(ADA Standards), German Standard(DIN 18040-1), Austrian Standard($\ddot{O}NORM$ B 1600) and Swiss Standard(Norm SIA 500) were investigated and analyzed. Results: Korea's standards differ from the ISO and the Standards of other countries in many ways, so there is a need for realignment. Specifications for disabled toilets and clear criteria for the size, shape, and location of sanitary appliances in toilets that are practically available to wheelchair users should be provided. Considering the increasing number of disabled toilet users, the installation of various disabled toilet rooms should be considered considering the user characteristics of those who can walk and wheelchair users. Implication: Recent partial improvements to relevant laws cannot meet the requirements of various users. Therefore, comprehensive and clear standard should be presented that take into account changing society and the environment.

  • Under current international investment law clear criteria to determine standards of indirect expropriation are absent. Arbitral tribunals determine on a case-by-case whether an indirect expropriation has occurred by conducting a fact-based inquiry. However, three common determination standards can be inferred by analyzing prior arbitration cases. The appropriate analytical framework that can be applied to determine whether a state's measure constitutes an indirect expropriation is as follows. i) the degree of economic invasion of the state's action into the foreign investor's property rights and durability of the period, ii) interference with the foreign investor's distinct and reasonable investment-backed expectations, and iii) the nature, purpose and character of the state's measure. Therefore, it is necessary to fully acknowledge and to utilize strategically this determination standard. However, derived standards cannot be applied to all disputes en masse. So, it is desirable to exclude ambiguity and to clearly define the determination standard of indirect expropriation in investment agreements, since arbitral tribunals can apply different determination standards on a case-by-case basis. And, based on the discussions until now, more developed standards and direction in response to demand should be established through consistent analysis and review of precedents related to indirect expropriation. Lastly, This study is expected to be a useful guideline to prepare a necessary countermeasure to prevent dispute related to indirect expropriation beforehand or in case of dispute occurrence.

  • The activity measurement of a solution of $^{133}Ba$ which is an electron capture nuclide was carried out by the ${\beta}-{\gamma}$ coincidence method. The counting rates at the ${\beta}-,\;{\gamma}-$, and coincidence-channels were measured using a $4{\pi}$ proportional counter and two NaI(Tl) scintillation detectors. The specific activity of the solution calculated by the efficiency extrapolation was $(1151.01{\pm}2.99)kBqg^{-1}$ at the reference time(00h UT, 03-15-84). According to an international comparison of activity measurements organized by the Bureau International des Poids et Mesures, this result showed the difference of 0.94% to the mean value derived from the comparison.

  • Smart clothing products can experience a decrease in performance and reliability due to various mechanical, biological, and chemical stress factors that occur throughout their life cycle. These issues can hinder consumer acceptance of the products. This study aims to enhance the reliability of smart clothing and facilitate quality control by analyzing and identifying the current status of international standardization for smart clothing and electronic textiles (e-textiles). The focus of this analysis was on the durability test methods in the use environment. Furthermore, similar standards published by different standardization organizations for durability tests were compared in depth. The study showed that a total of 27 international standards have been developed or are currently under development. The current standardization efforts mainly aim to develop functionality and durability test methods for smart clothing and e-textile products. A detailed comparison was made between two international standards (IEC 63023-204-1:2023 and AATCC TM210:2019) specifically in relation to the washing durability test method and the electrical resistance measurement standards (BS EN 16812:2016 vs AATCC EP13-2021), before and after the environmental exposure tests. Based on this comparison, several suggestions have been made and discussed for the future revision of these international standards.

  • Purpose: The manoeuvring space at doors must be secured for users of walking aids, wheelchair users, stroller users, luggage carriers, etc., so clear criteria must be established. The korean standards for the manoeuvring space at doors need to be improved to present clear criteria depending on the type of entrance and the direction of opening and closing. Method: Korean standard, International Standard(ISO 21542, 2011), German Standard(DIN 18040-1, 2010), Austrian Standard(OENORM B 1600, 2017) and Swiss Standard(Norm SIA 500, 2009) were investigated and analyzed. A comprehensive improvement of the criteria for the manoeuvring space at doors is proposed. Results: The manoeuvring space at doors, which is essential for the disabled to use the door, shall be installed with a comprehensive consideration of the width of doors, the Circulation space, the direction of access, and the method of opening and closing of the door. Korean standards, such as the width of doors, the Circulation space, and the manoeuvring space at doors, are different from international and international standards, which require improvement of standards. The criteria for the manoeuvring space at doors shall be clearly improved so as not to be misinterpreted during the installation of doors and the BF-certification. Implication: The criteria for the installation of doors shall be presented as a comprehensive alternative through continued study of details. In addition, improvements in standards that reflect changes in international standards should be made.

  • The purpose of this study is to establish the training standards for HF of aviation maintenance reflecting the growing relevance of aviation maintenance technicians' ability to perform their work for the safety and efficiency of airline operation. For this purpose, previous studies on the concept of human factors were examined, and the HF training standards of the advanced international aviation bureaus such as the International Civil Aviation Organization(ICAO), Federal Aviation Administration(FAA) and European Aviation Safety Agency(EASA) were compared with the operational technical standards of Korea Aviation Safety Law. In addition, the actual status of human factors education and training were examined for Korea's two full service carriers (FSC) and four of the low cost carriers (LCC). The study results revealed that Korea's human factors education and training standards were weak compared with international standards, and that most airlines were not able to systematically implement human factors education and training. These results complement the existing problem of training standards for aviation maintenance human factors in Korea and support the development of a standard model of the training course for aviation maintenance human factors which meets international standards.
