This study aims to explore the agency and social interactions of an immigrant child, identified as a shy girl with a school adjustment difficulty. Data were collected through class observations and interviews with the child’s teachers and mother. The findings highlight how this immigrant child showed her active agency in building relationships with others and adapting to and negotiating with class rules. The material settings, class rules, physical space, classmates, and/or teachers’ presence...

Well-dispersed Ag₃VO₄ nanoparticles @polyacrylonitrile (PAN) nanofibers were synthesized by an easily controlled, template-free method as a photo-catalyst for the degradation of methylene blue. Their structural, optical, and photocatalytic properties have been studied by X-ray diffraction, transmission electron microscopy, field-emission scanning electron microscopy equipped with rapid energy dispersive analysis of X-ray, photoluminescence, and ultraviolet?visible spectroscopy.

Electrochemical synthesis was employed to prepare a novel hydroxyapatite/graphene (HAP/ Gr) composite powder suitable for medical applications as a hard tissue implant (scaffold). The synthesis was performed in a homogeneous dispersion containing Na2H2EDTA·2H2O, NaH2PO4 and CaCl2 with a Ca/EDTA/PO4 3? concentration ratio of 0.25/0.25/0.15M, along with 0.01 wt% added graphene nanosheets, at a current density of 137 mA cm?2 and pH value of 9.0. The field emission scanning electron microscopy and...

Conductive polymer composites (CPCs) consist of a polymeric matrix and a conductive filler, for example, carbon black, carbon fibers, graphite or carbon nanotubes (CNTs). The critical amount of the electrically conductive filler necessary to build up a continuous conductive network, and accordingly, to make the material conductive; is referred to as the percolation threshold. From technical and economical viewpoints, it is desirable to decrease the conductive- filler percolation-threshold as...

Carbon nanofibers (CNFs) with diameters in the submicron and nanometer range exhibit high specific surface area, hierarchically porous structure, flexibility, and super strength which allow them to be used in the electrode materials of energy storage devices, and as hybrid-type filler in carbon fiber reinforced plastics and bone tissue scaffold. Unlike catalytic synthesis and other methods, electrospinning of various polymeric precursors followed by stabilization and carbonization has become a...

Diverse and comprehensive countermeasures were established to prevent water pollution in coastal areas such as constructed wetlands(CW).This study was conducted to assess the water quality improvement through CW constructed along the shoreline of Hwaseong coastal reservoir. The CW is located in Hwaseong-si, Gyeonggi-do and consisted of a forebay and a wetland. The CW was monitored twice during rainy days and 10 times during dry days. The monitoring results indicated that in and out flowrates...

We examined whether an artificial levee constructed on prime amphibian habitat influences fragmentation. Four different sites on both sides of a levee in the Civilian Control Zone(CCZ) were probed. Sites 1 and 2 are rice paddies on one side of the levee, and Site 3 is the stream that locates in the same side. All the three sites have water conditions of seasonal variance. On the other side, Site 4 consists of rice paddies with a stable condition of water supply, irrigated through a canal. The...

This article examines the place of global citizenship education in schools by critically analyzing the official curriculum in one US state, Georgia. Data in the study includes Georgia Department of Education documentation about the implementation of the K-8 Georgia Performance Standards for Social Studies, particularly the 6th and 7th grade “world studies standards”. An interpretive document analysis is used to identify patterns of inclusion and exclusion which are then examined to assess...

21세기 들어 한국 사회가 다문화사회가 되어가는 추세다. 이 연구는 최근 영미권에서 다문화주의(multiculturalism)와 세계화(globalization) 등을 다루는 연구를 검토함으로써 한국의 미래지향적인 다문화사회가 무엇인지 그리고 그 사회에서의 구비문학의 역할을 알아보는 데에 목표를 삼았다. 먼저 구비문학･민속학 연구자와 인접 분야 연구자들이 20세기 말까지 다문화주의의 문제에 대해서 고민한 것을 보았는데 여기서 정체성의 중요성을 알 수가 있었다. 특히 민속의 연행은 어떤 정체성을 공유하는 사람들끼리만...
