The purpose of this study is to investigate the perception of Chinese early childhood teachers on early childhood education for sustainable development (ESD) and the current status of early childhood ESD in Chinese kindergartens. For this purpose, an online survey was conducted from July 11 to July 23, 2021 for 169 incumbent early childhood teachers working in kindergartens in China. Frequency analysis and cross-analysis were performed on the collected data using the SPSS program. The results of the study are as follows. First, early childhood teachers in China showed high interest in ESD and willingness to participate in related education, but their experience of participating in actual education and related activities was relatively low. Second, although the need for early childhood ESD was highly recognized, there were relatively few teachers who provided education for sustainable development in kindergartens. Third, early childhood teachers in China thought that the lack of understanding of ESD and the lack of professionalism of teachers were the obstacles in implementing ESD. To revitalize ESD, they demanded the development and dissemination of ESD programs, the provision of knowledge and information on ESD, and the provision of teacher education dealing with practical methods of instruction and specific methods of communication with children. Therefore, continuous discussion and efforts are required for the development of the ESD program for children in China and ways to improve the professionalism of teachers.
개념 공간 이론으로 본 한국어 ‘아무’ 계열과 중국어 ‘任何’ 계열의 특징 연구

Based on the conceptual space of indefinite pronouns proposed by Haspelmath, this paper systematically organizes the various structures of the ‘任何’ set in Chinese and the ‘아무’ set in Korean, concludes their functions in the conceptual space, and makes the semantic map, through which similarities and differences of those functions can be visually compared. By analyzing the respective function semantics of the two sets of ‘任何’ and ‘아무’, the paper is based on the similarities and differences of semantics and explores the semantic contact between these functions so as to make a comparison on semantics of the ‘任何’ set and the ‘아무’ one. Moreover, on the basis of the comparative analysis of Chinese and Korean, this paper questions the conceptual space of indefinite pronouns raised by Haspelmath and makes a tentative revision on it.

<P>Soft and conformable wearable electronics require stretchable semiconductors, but existing ones typically sacrifice charge transport mobility to achieve stretchability. We explore a concept based on the nanoconfinement of polymers to substantially improve the stretchability of polymer semiconductors, without affecting charge transport mobility. The increased polymer chain dynamics under nanoconfinement significantly reduces the modulus of the conjugated polymer and largely delays the onset of crack formation under strain. As a result, our fabricated semiconducting film can be stretched up to 100% strain without affecting mobility, retaining values comparable to that of amorphous silicon. The fully stretchable transistors exhibit high biaxial stretchability with minimal change in on current even when poked with a sharp object. We demonstrate a skinlike finger-wearable driver for a light-emitting diode.</P>
