A Quasi-experimental Research on the Effects of Explicit Grammar Instructions on English Performance ofChinese University Students Li Ke* Abstract: This study aimed at the impact of explicit English grammar instruction on students’ performance in English tests for Chinese non-English major university students. Through an eight-week experimental teaching method, it was found that the experimental class under the explicit grammar instruction showed greater overall improvement in English comprehensive exams compared to the control class without specific grammar instruction. Independent sample t-tests on pre- and post-test scores between the two classes and paired sample t-tests within the experimental class revealed that students in the experimental class showed more significant progress in reading, translation, and writing, without significant impact on listening. The results suggested that in the Chinese university English teaching context, the utilization of explicit grammar instruction may generate a positive impact on students’ performance in English exams.

Characteristics of the China's Power Elites in the 21^(st) Century : Continue or Change?

Kim, Jung Ke 대한정치학회 2005 大韓政治學會報 Vol.13 No.2

This study focused on the backgrounds of the current CCP PB members, and what characteristics changed or continued when compared to the previous one. The subject of research was the top 203 PB members since 1949, a cluster of elites that includes the current 24 PB members. The analytical categories of the backgrounds were: 1) biological backgrounds, 2) educational backgrounds, and 3) work backgrounds. In brief, the results of analysis show all of the 16^(th) PB in their age, growth time, the time of graduated college and joined the Party, or work experience are different from the third generation. However, the 16^(th) PB members have advanced their careers by working on China's economic modernization program, they were technically trained and by profession technocrats in administrative capacities, similar to their immediate predecessors. Therefore, the new leadership will not necessarily translate into distinctive policy orientation.

Remote Sensing field uses mainly Landsat TM image that is used to the monitoring of the wide area. In this study, it is analyzed the Water System Effect Area by time series using satellite images and is proposed the vision for a urban balanced development. It execute an analysis for urban change which is a fundamental data of floodgate planning through the integration of the spatial analysis technique of GIS and Remote Sensing using satellite data

誤謬分析과 對照分析의 方向과 그 適用

Foreign speakers of a target language often produce ungrammatical utterances. We may look of the causes of these deviant structures in different areas, interference from the native language and that from the complexity in the foreign language itself. Moreover, certain errors may be attributable to general learning strategies. Contrastive analysis has proved valuable to predict interlanguage interference. Many errors, however, can not be explained by contrastive analysis, therefore, we have to look elsewhere for explanations. A detailed analysis of errors done by Tran-Thi-Chau revealed that interlingual interference was the greatest cause of errors, and intralingual errors formed the second largest group of errors. The results of this experiment support the belief that unless EA makes use of CA insight it can not explain the causes of a large number of errors. Consequently, the two types of analysis are complementary rather than exclusive. On the basis of this investigation, I attempted to analyze the errors made by Korean examinees who took the English Proficiency Test at the Language Research Institute, Seoul National University. The corpus mostly consists of oral and written production in English. The errors were classified into two categories, interlingual and intralingual (also developmental). For convenience of presentation, the latter was classified into two groups, over-generalization and under-generalization. Grammatical categories with examples are presented in the paper, where a considerable amount of teaching should be devoted.

1. 섬유소 생물자원을 이용하여 纖維素資化能의 單細胞蛋白質을 生産하기 爲하여 소와 양의 反芻胃에서 Hungate's roll tube method에 의하여 통성혐기성 섬유소 분해세균 21株를 분리하였으며, 그 중에서 가장 섬유소 분해력이 강한 1株를 선발하여 형태학적, 배양학적, 생리학적 특성을 검토하여 同定한 결과 Cellulomonas fimi C-14이었다. 2. 분리 同定된 Cellulomonas fimi C-14의 균생육 및 효소생산의 최적 조건은 온도 30℃, pH6.5이었고, 생산된 조효소는 40℃, pH6.0에서 최대역가를 나타내었으며 그 때의 C₁,??, β-glucosidase ,역가는 20.6, 226.6, 0.56(mㆍunit)이었다. 3. 곰팡이 Cellulase의 첨가로 酵素力價가 증가하였으며, 현사시나무의 톱밥을 기질로 호모 菌體生産時 상승효과가 나타났으며, 낮은 농도의 xylose, glucose에서도 발효능이 좋은 균주로 선발된 Candida guilliermondii를 접종하였을 때 이단계 발효법보다 동시당화 발효법의 菌體生産 수율이 높았다. 4. 톱밥기질에서 곰팡이 Cellulase 첨가와 Cellulomonas fimi C-14와 Candida guilliermondii를 접종하여 동시당화 발효법으로 菌體乾物量 4.5g/l를 얻을 수 있었으며 이 때의 기질인 톱밥은 2-Naphthol 처리 및 자가가수분해, 脫리그닌 처리된 것이었다. From the sheep's and cattle's rumen, facultative anaerobic cellulolytic bacteria were isolated by using Hungate's roll tube technique. In the 21 isolated species, one was screened by it's strong cellulolytic activity and identified as Cellulomonas fimi C-14 by investigate morphological, cultural, physiological characteristics. Optimum conditions of the cell growth and enzyme production were pH 6.5 and 30℃. In the enzyme activity, Crystalline cellulose hydrolyzing activity, Carboxy methyl cellulose hydrolyzing activity, and β-glucosidase activity were 20.6, 226.6 and 0.56 (unit×10³/ml) at pH 6.0, 40℃. By addition of fungal cellulase, enzyme activity was increased. Candida guilliermondii was selected for S.C.P production under low sugar concentration. S.S.F. (Simultaneous Saccharification Fermentation) is higher than two step fermentation in cell yield. Sawdust was autohydrolyzed and treated 2-naphthol, then delignified by Wise's method. Maximum dry cell yield was 4.5g/ℓ from 2% of the Populus albaglandulosa sawdust substrate by use of C. fimi C-14, Candida guilliermondii and addition of fungal cellulase through S.S.F. method.

This study aims at determination of probability floods for the certral area of Korea. The analysis is based on the existing flood records, 1952 to 1982 at 10hydrologic stations excluding the data which affected the artificial control of discharge after dam construction. Here, We inputed the date for floods in each station to the computer program made with Log-normal, Gumbel Chow, Takase, Iwai method and determined the probability floods in each return period and compared with each frequency curve for each station. The results from this study might be useful tools to determine the floods for hydrologic structures at the place wherer no data are available.
