Korean English Teacher's Disempowerment in English-only Classes

Hwang, Sung-Sam, SeD, Hyo-Sun, Kim, Tae-Young. 2010. Korean English Teacher's Disempowerment in English-only Classes: A Case Study Focusing on Korea-specific Cultural Aspects. The Sociolinguistic journal of Korea 18(1). In this case study, we have focused on the disempowerment of a Korean English teacher (KET) in English-only classrooms. Six English as a foreign language (EFL) classrooms in a Korean high school were observed and analyzed by using interpretive discourse analysis. Out of the six classes, three representative classrooms were both video- and audio-taped. The results show that the English-only classes could weaken the KETs' power via three mechanisms: (a) calling the KETs' last name for choral greetings at the beginning of the class, (b) students' group solidarity and peer pressure between classmates, and (c) the students' excessively collaborative approach to peer assistance. It is argued that the exclusive English-only instruction disempowers the KETs' status and dismantles their vocational identity. In order to remedy the current situation, within a scaffolding supported by the eclectic use of first language where necessary for effective class management, KETs are empowered and overcome constraints imposed by the limited L2 oral competence of some non-native English teachers.

자아 이미지와 브랜드 퍼스낼리티 관련성에 관한 연구

이상욱,김삼근 안성산업대학교 1998 論文集 Vol.30 No.-

Personality traits come to be associated with a brand in a direct way by the people associated with the brand-such as the brand's user imagery, which is defined here as "the set of human characteristics associated with the typical user of a brand". In this research, the authors develops the relationship between self-image and brand personality. This research have focused on how the personality of a brand enables a consumer to express his or her own self, an ideal self, and specific dimensions of the self through the use of a brand.

Extraction yields of Zunthoxylum piperiturn by organic solvents and supercritical carbon dioxide(SC-CO_(2)) with and without ethanol as a cosolvent, and antimicrobial activities of the extracts against Hucillus cereus were determined. Extraction yield by distilled water was the highest, 20%, while those by ethanol, ethyl ether and hexane were less than 3%. Extraction yield by SC-CO_(2) Lvith ethanol was 1.42 times greater than that by only SC-CO_(2). Ethyl ether- and ethanol-extracts had potent antimicrobial activities against B. cereus. Extraction yield by SC-CO_(2) with ethanol showed almost the same degree of microbial growth inhibition as that by only SC-CO_(2).

傳統建築物保存地區내에서의 燃燒速度式을 고려한 防災計劃의 수립과 災難危險度評價 시스템 構築에 관한 硏究

The purpose of this study is to set up disaster prevention plan and risk assessment system considering combustion velocity at traditional housing zone. The combustion velocity analysis could contribute to build in disaster prevention technique through the potential risk analysis of the area, such analysis also able to set up comprehensive disaster prevention management system. Following results have achieved through the combustion velocity calculation. ① The combustion velocity was calculated in order of the below winds, the above winds and the side winds. ② It must be careful to set up disaster prevention plan in case of the below winds. ③ The combustion velocity was calculated at the density zone where neighboring Distance and Length was small. ④ It proved that factors of each parameter not mostly effect to analyse the combustion velocity in limit of the 30 minutes after ignition. ⑤ At the density zone where Distance and Length is small the duration of transfer to neighboring house takes up to 4 minutes, it is required to set up of emergency response plan to minimize the fire dispersion. Keywords : Combustion velocity, Disaster prevention, Risk assessment

水稻種子의 Paclobutrazol浸漬處理가 苗素質에 미치는 影響

This experiment was carried out to evalute the effects of paclobutrazol (PP-333) on the characters of mechanical transplanting rice seedlings at the Chungbuk National University in 1986. The results obtained were summarized as follows. 1.Paclobutrazol appeared to be very effective to reduce plant height of seedlings. Highly significant difference in plant height of seedlings among paclobutraszol concentration was noted for all varieties tested. 2.Paclobutrazol at higher than 10 ppm increased the number of leaves of 40-day-seedlings for all varieties. It appeared that number of leaves was increased as paclobutrazol concentration was increased. 3.Although dry weight of seedlings was reduced, dry weight/plant height, which indicates the degree of seedlings substantiality, tended to be increased as paclobutrazol concentration was increased.

This experiment was carried out to know the effect of agricultural ehemicals as a fruit thinner of apple varieties such as Fuji, yellow delicious, Jonagold and starkrimson with sevin and smithion in 1990. The results were as follows. 1) Fuji cultivar showed higher thinning effect with sevin and smithion in the center fruit. Trees treated with smithion was 89.3% in the side fruit and 67.5% in thinning rate with sevin 2) Simmilar thinning effect were shown in yellow delicious and starkrimson cultivars, too. 3) Jonagold cultivar showed striking thinning effect and that side fruits were dropped cntirely. This cultivar seemed to response well. From these results, agricultural chemicals, sevin and smithion can be applied as a thinning agent for apple cultivars effectively without any injury to the tree, the authors believed.

신생흰쥐의 피부내 Fibronectin의 분포변화에 대한 면역조직학적 연구

홍성희,정호삼 大韓成形外科學會 1998 Archives of Plastic Surgery Vol.25 No.2

Fibronectin is a well known glycoprotein of extracellular connective tissue matrices due to a specific amino acid-sequence(RGD) suggested to act as an attachment factor in cell-cell or cell-matrix interactions. Although also present in dermis of skin, little is known about the distribution of fibronectin in the skin. To obtain data for distribution on skin, we used immunolocalization techniques to quantitatively examine the distribution of fihronectin in various layers of skin by developmental stages of rats. The study was focused on fibronectin distributions of skin in 7 developmental stages of newborn rats. The results were obtained as follows. 1. Stratum lucidum and granulosum in epidermis showed the strong fibronectin immunoreactivities from day 1 to day 5 neonatal stages of rats. But at the 1st week after birth, fibronectin immunoactivities on the epidermis were diminished as much as those of control group rats. 2. At 1 day and 5 day after birth, strong immunoreactivities of fibronectin were seen in papillary layer of dermis moderate or wreak immunoreactivities in reticulum layer of dermis. 3. At the epidrmal-dermal bored(basement membrane) and hair follicles, moderate fibronectin immunotivities were increased from 1 day to 5 day after birth. But from the 2nd week after birth, immunoreactivities of fibronectin were decreased to be weak reactions. It is suggested that large amounts of the fibronectin distribution in the neonatal rat skin will be devoted to rapid formation of dermal tissue.

This paper proposed a versatile Microcomulator Simulator Generator (MCSG) programmed in FORTRAN. This Generator MCSG can be applied to any general and can be used to produce a FORTRAN microcomputer simulator if the hardware purpose computer information and micro-operation sets are provided. A graphical representation technique was proposed for the analysis and comparison of four typical microcomputer systems selected for the generation and test of the simulator.
