Development and Application of an Experience Activity Task related to New and Renewable Energies and Energy Conversion in Middle School Technology and Home Economics
Dong-Yeon Park, Kyung Taek Lee 한국교원대학교 뇌기반교육연구소 Brain, Digital, & Learning 14 Pages
한국교원대학교 뇌기반교육연구소 Brain, Digital, & Learning 2018, 제 8권 제 4호 3 165-178 (14 pages)
based on the problem solving approach. Next, an experience activity task on making temperature difference generators and electric refrigerators , that can pursue the understanding of renewable energy and energy conversion at the same time and to be applied to real life, was developed. Also, a teaching-learning process consisting of 8 classes, teacher study materials and student study materials were developed. Finally, the validity of these outcomes was verified by the related experts of 7... -

The Internet of Things (IoT) and the Smart Grid both are being discussed as the technologies that would dominate Korean IT industry by 2020. The PLC, Zigbee, NFC, ANT, Wi-Fi, Bluetooth and RFID are considered to be the foundation technologies for the Smart Grid and in this paper, we propose a Zigbee-based Smart Grid Home Network System. A comparative analysis has been carried out by performing additional Mobile WiMAX-based simulations with respect to the research paper published in the... -
Life Chances and Birth Registration: A Study from Rural China
Berenice Nyland, Yang Gao, Zeng Xioadong, Josephine Ng 환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 26 Pages
환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2016, Vol.10 No.3 4 71-96 (26 pages)
In recent years early childhood education has become a focus for ambitious reforms in China. The emphasis on early experiences in this study was designed to address issues of unequal life chances, that is, the opportunities that individuals have to improve their lives across the life span. Children in rural China are more likely to be educationally disadvantaged and lack of birth registration compounds this problem. This paper examines data from rural China that was designed to collect household... -
Thermoelectric Seebeck and Peltier effects of single walled carbon nanotube quantum dot nanodevice
H. A. El-Demsisy, M. D. Asham, D. S. Louis, A. H. Phillips 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2017, Vol.21 2 8-15 (8 pages)
The thermoelectric Seebeck and Peltier effects of a single walled carbon nanotube (SWCNT) quantum dot nanodevice are investigated, taking into consideration a certain value of applied tensile strain and induced ac-field with frequency in the terahertz (THz) range. This device is modeled as a SWCNT quantum dot connected to metallic leads. These two metallic leads operate as a source and a drain. In this three-terminal device, the conducting substance is the gate electrode. Another metallic gate... -
