Activating needle coke to develop anode catalyst for direct methanol fuel cell
Young Hun Park, Ui-Su Im, Byung-Rok Lee, Dong-Hyun Peck, Sang-Kyung Kim, Young Woo Rhee, Doo-Hwan Jung 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 7 47-52 (6 pages)
Physical and electrochemical qualities were analyzed after KOH activation of a direct methanol fuel cell using needle coke as anode supporter. The results of research on support loaded with platinum-ruthenium suggest that an activated KOH needle coke container has the lowest onset potential and the highest degree of catalyst activity among all commercial catalysts. Through an analysis of the CO stripping voltammetry, we found that KOH activated catalysis showed a 21% higher electrochemical... -

A Choice of Nightmares: The Fisher King and the Horror in Heart of Darkness and Apocalypse Now
Youngkul Kim 이화여자대학교 교과교육연구소 Eastwest Education 46 Pages

This study investigates Joseph Conrad's Heart of Darkness and its film adaptation, Francis Ford Coppola’s Apocalypse Now, by examining the character of the Fisher King, a common figure at the beginning of human society who was later incorporated into romance literature, especially in the quest for the Holy Grail in the Arthurian legend. A superior warrior of godlike proportions, he leads his people to health and prosperity; as Fisher King, however, he becomes sick, and that sickness is... -
Rethinking Story Reading in U.S. Preschools: Making Story Comprehension and Social-Emotional Understanding the Priority
Judith A. Schickedanz 환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 21 Pages
환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2014, Vol.8 No.2 2 5-25 (21 pages)
This paper begins with a brief historical overview that provides a context for understanding approaches to story reading in U.S. preschools. It also discusses factors that have prompted a new trend in story reading, one emphasizing story comprehension directly, not as a vehicle for developing only oral vocabulary and print-related literacy skills. This backdrop, as well as discussions of new research and achievement difficulties in school-age children, sets the stage for the author’s suggestion... -
Unveiling the Challenges of Home-School Collaboration in Special Schools of Nepal
Jung Dae Young, Nam Raj Neupane 한국통합교육학회 통합교육연구 23 Pages
한국통합교육학회 통합교육연구 2019, 제 14권 제 1호 3 57-79 (23 pages)
The study attempts to investigate current realities and challenges of home-school collaboration in the special schools of Nepal. The study is based on qualitative paradigm and followed by descriptive research design. Five special schools from Kathmandu valley (Kathmandu, Bhaktapur and Lalitpur districts) were selected for the study by purposive sampling method. From these schools, five head teachers were automatically selected, five teachers and five parents (one from each school) were selected... -
Catalytic hydrogenation-assisted preparation of melt spinnable pitches from petroleum residue for making mesophase pitch based carbon fibers

We demonstrated an effective way of preparing melt spinnable mesophase pitches via catalytic hydrogenation of petroleum residue (fluidized catalytic cracking-decant oil) and their subsequent thermal soaking. The mesophase pitches thus obtained were analyzed in terms of their viscosity, elemental composition, solubility, molecular weight, softening point and optical texture. We found that zeolite-induced catalytic hydrogenation under high hydrogen pressure contributed to a large variation in the...
