Purpose: This study aims to identify the hindrance factors of ICT-integrated education in Addis Ababa, Ethiopia from a multifaceted perspective and suggest essential factors that should be considered in the implementation of ICT-integrated education in Ethiopia and other developing countries. Originality: This study contributes as the first study to identify the hindrance factors of ICT-integrated education through a comparison of prior research and empirical data by systematically categorizing individual, organizational, and national levels. Methodology: It employs a qualitative case study method to understand the relationships and interactions of the complex factors involved in ICT-integrated education. Data were collected through semi-structured interviews, classroom observations, document analysis, and focus group interviews. It was analyzed by using a hierarchical framework of individual, organizational, and national levels. Result: This study has identified a number of hindrance factors from each level that can only be found in the context of Ethiopia, including common factors. These factors are analyzed to explore how ICT-integrated education can be improved. Conclusion and Implication: This study explored the hindrance factors that can be used as a reference for other cities in Ethiopia and developing countries facing difficulties in the implementation of ICT-integrated education. It will provide important implications for future research as well as ICT education development cooperation projects.

This paper examines how study abroad students pursue and negotiate linguistic authenticity to maximize their English improvement during their overseas stay. For this purpose, data was drawn from a 13-month ethnographic fieldwork of South Korean post-secondary learners studying English in Toronto, Canada. Study abroad programs are believed to give students authentic learning experiences by allowing them to immerse themselves in a local culture and communicate with local people imagined as native speakers. However, it has been reported thatmost study abroad learners have difficulty with accessing local communities and building close relationships with native speakers. This paper reveals that to deal with these immersion challenges, South Korean young adults strived to identify and access three types of English speakers in their trajectories of studying English abroad: 1) “Canadians,” 2) “proficient” non-native English speakers, 3) “family-like” teachers at school. However, as they established such boundaries of English speakers according to their language ideologies and learning needs, their trajectories of accessing each type of English speakers did not unfold as they had planned. The paper concludes by discussing pedagogical implications for effective study abroad programs. (179 words)
Multilingualism in the Linguistic Landscape of Konkuk University Glocal Campus

The globalization of higher education has reshaped language use and practice on campus. As increasing numbers of international students change the campus into a more multilingual space, a variety of multilingual signs posted on bulletin boards and streets on campus become commonplace. Against such a backdrop of sociolinguistic changes on the globalizing campus in higher education, this study explores the ways in which multiple languages are chosen and used in South Korean higher education. Drawing on the framework of linguistic landscape, the present project analyzes multilingual signs displayed in public spaces of Konkuk University Glocal Campus, a local university that has pursued internationalization policies over the past decade. For this purpose, 208 public signs were collected from thirteen locations and analyzed in terms of language, producers, and communicative functions. The analysis reveals that a typical multilingual sign is in English and Korean and is created by the university authorities for referential functions. The most multilingual spaces are the library, a building for international education, and the dormitory, as these locations display various languages and language combinations. English is the most dominant foreign language in multilingual signage. Chinese and Vietnamese signs have begun to be increasingly present at KU, but their communicative functions are relatively limited. Based on such findings, implications for the university’s language and internationalization policies are also discussed.

Through-hole PCB(Printed Circuit Board) was soldered by flow soldering process using cleaning or noncleaning fluxes. Preheating temperature and conveyor speed were changed in the range of 323∼413K and 0.3∼2m/min respectively. The soldered joints were tensile tested in order to evaluated bonding strength. As experimental results, relatively high tensile fracture load, 120∼140N, were obtained in case of preheating temperature of 383K, and conveyor speed was 0.6∼1.0 m/min. Fractured surfaces of higher tensile strength show some dimple area, while those of lower tensile fracture load show brittle fracture.
Antioxidant Activity of 4 Cultivars of Persimmon Fruit

In this study, the antioxidant activity of persimmon fruit of 4 different persimmon cultivars cultured at Korea was evaluated. There were 3 astringent persimmon cultivars [‘Bongok’ (BO), Japanese Hatchiya; ‘Cheongdobansi’(CB); and ‘Dogeunjosaeng’ (DJ), Japanese Tonewase] and 1 non-astringent persimmon cultivar [‘Seochonjosaeng’(SJ), Japanese Nishimurawase] fruits. After preparing extracts of fruits according to parts (calyx, pulp, and peel)with 4 different solvents (acetone, ethanol, methanol, and water), total phenolic contents (TPC) and antioxidant activity were determined. The extracts of calyx showed significantly higher TPC and antioxidant properties than those of the other persimmon parts. The highest 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity (IC_50=43.36±1.78 μg/mL) and reducing power (IC_50=81.93±1.18 μg/mL) were found at acetone extract of SJ calyx, while SJ pulp extracts showed relatively lower antioxidant activities. Astringent persimmons showed relatively higher antioxidant activity than non-astringent persimmons in peel and pulp parts. These results indicated that persimmons have different antioxidant activity depending on cultivars and parts.
