This is to summarize a joint discussion on the future of EAMA in EAMA6. The emphasis was placed on the near future instead of the distant future, Formation of the Working Groups as a means to carry the cooperation for the regions was generally agreed by the attendants of EAMA6 to be the best way toward the establishment of future East Asian Observatory (EAO). Association of Core Observatories (ACO) was proposed to bring resources and foster joint projects for EAMA activities.

Rare earth elements (REEs) are considered to be vital to modern industry due to their important roles in applications such as permanent magnets, automobile production, displays, and many more. The imbalance between demand and supply of REEs can be solved by recycling processes. Regarding the needs of industry and society, the International Organization for Standardization, Technical Committee 298 (ISO/TC298) Rare Earths has been recently launched for developing international standards on rare earth elements. In accordance with the suggestion of its constituents, it is tentatively working to develop the appropriate standards under five working groups (WG) on terms and definitions (WG1), element recycling (WG2), environmental stewardship (WG3), packaging, labelling, marking, transport, and storage (WG4), and testing analysis (WG5). The scope and structure of ISO/TC298 on the topic of rare earths is discussed in this document.

ISO/IEC JTC 1/SC 29(멀티미디어부호화) WG 11(MPEG)에서는 미디어 산업 전반에 대한 표준화를 다루고 있으며 해당 산업과 연관된 다양한 기관들과의 교류가 진행되고 있으나, 작업반(WG)이란 한계와 현행 ISO/IEC 규정에 의해 다양한 표준화 단체들과의 교류에 많은 제한이 있었다. 이에, 2019년 7월 관련 임시 작업반(AhG)이 설립되어 구조조정에 대한 논의를 진행했으며, 2020년 7월에 열린 37차 JTC 1/SC 29 총회에서 기존 WG 11을 폐지하고 새로운 작업반을 신설했다. 이에 본 논문은 JTC 1/SC 29/WG 10(MPEG) 구조조정 결과 및 신설 작업반의 구조와 표준화 동향을 알아본다.

This paper introduces main activities of ISO/TC 108/SC 3 and published standards. Two working groups (WG 1 and WG 6) have been orgnized to review and revise ISO standards, specifically related to measurement and calibration subjects of vibration and shocks. A new joint working group (JWG1) with IEC/SC 47E (Semiconductor acceleration calibration) has started to deal with calibration methods for analog and digital output MEMS accelerometers. Finally, Published ISO standards, technically super-visored by ISO/TC 108/SC 3, are listed in this paper to help readers understand their main contents.

This study investigated factors affecting the bone mineral density (BMD) of Korean young adult women (20~30 yrs) living in Seoul, according to the state of employment. Data on BMD and anthropometric and biochemical measurements were obtained from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V) (2010~2011). BMD of the working group (WG) was generally higher than that of the non-working group (NWG). The prevalence of osteopenia, and osteoporosis between the groups was 29.0/31.5%, and 12.9/18.5% from 20~29 yrs as well as 25.5/24.1%, and 20.2/20.5% from 30~39 yrs, respectively. From 20~29 yrs, prevalence of osteopenia and osteoporosis in the WG was lower than that of the NWG. Alkaline phosphatase activity of the WG was lower than that of the NWG. In the WG, from 20~29 yrs, total femur BMD showed significant positive correlations with waist circumstance and BMI. In the NWG, from 20~29 yrs, total femur, femoral neck, and lumbar spine BMDs showed significant positive correlations with weight and fat mass, whereas they showed significant negative correlations with vitamin D. In the WG, from 30~39 yrs, total femur and femoral neck BMDs showed significant positive correlations with weight and free fat mass. The results of this study show that BMD of young adult women is insufficient regardless of their employment status. Therefore, practical and systematic programs are required to improve the BMD of young adult women as well as to maintain healthy bone levels.

ISO(the International Organization for Standardization) is a worldwide federation of national standards bodies, from some 120 countries. The technical work of ISO is highly decentralized, carried out in a hierarchy of some 2,700 technical committees(TC), sub-committees(SC) and working groups(WG). The results of the ISO work are published as International Standards. In this paper, main fields of work at the ISO/TC43/SCI are described.

Following a joint OECD/NEA-IAEA-sponsored meeting to define the current role and future perspectives of the application of Computational Fluid Dynamics (CFD) to nuclear reactor safety problems, three Writing Groups were created, under the auspices of the NEA working group WGAMA, to produce state-of-the-art reports on different aspects of the subject. The work of the second group, WG2, was to document the existing assessment databases for CFD simulation in the context of Nuclear Reactor Safety (NRS) analysis, to gain a measure of the degree of quality and trust in CFD as a numerical analysis tool, and to take initiatives to extend the existing databases. The group worked over the period of 2003-2007 and produced a final state-of-the-art report. The present paper summarises the material gathered during the study, illustrating the points with a few highlights. A total of 22 safety issues were identified for which the application of CFD was considered to potentially bring real benefits in terms of better understanding and increased safety. A list of the existing databases was drawn up and synthesised, both from the nuclear area and from other parallel, non-nuclear, industrial activities. The gaps in the technology base were also identified and discussed. In order to initiate new ways of bringing experimentalists and numerical analysts together, an international workshop -- CFD4NRS (the first in a series) -- was organised, a new blind benchmark activity was set up based on turbulent mixing in T-junctions, and a Wiki-type web portal was created to offer online access to the material put together by the group giving the reader the opportunity to update and extend the contents to keep the information source topical and dynamic.

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.
