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. Key Words: English Teaching, Grammar Instruction, Explicit Syntactic Instruction, Second Language Acquisition, Chinese University Students □ Received: May 16, 2024, Revised: June 3, 2024, Accepted: June 20, 2024* Professor, Shandong Technology and Business Univ., Email: likeby@sina.com

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

The 229 strains of black Aspergillus sp. producing citric acid were isolated from soil. Among them, the strains KTR-81 and KTR-91 were found to be superior for citric acid production. Their basic cultural conditions as well as high citric acid producible conditions from the liquefied sweet potato cake which is a byproduct obtained from waste material in the production of sweet potato starch, were investigated, and the results obtained are as follows: 1. Those two strains produced citric acid to maximum 63.0-63.5% from glucose when the liquefied sweet potato cake media had 16% in its total sugar concentration. The nutritional conditions added to the media were 0.15%, 0.06% and 0.03% of urea, mixture of equal amount KH_2PO_4 and K_2HPO_4, and MgSO_4·7H_2, respectively. Some hindrances were likely to be appeared in the production of critic acid by the change of the amount of the nutrients as shown above. 2. Since the oxalic acid-forming activities are relatively dull, those two strains may be available for the citric acid fermentation industry.

According as a complexity and high level of society, the information being rapid and accurate for landuse, environment and traffic etc. is required, but the information management by a drawing and a map is confronted with a complicated and sudden change of facilities. For the facility management, the condition of all facility must be understood and facility drawing of those days of construction must be kept well, but there are many problems for the facility management because of keeping a drawing and a map carelessly up to now. To solve these problems and preserve a drawing and manage facility efficiently, the facility management is required. The study include the methodological problems for the techniques and procedures to design database necessitating great cost and time to establish the facility management system. Furthermore, all sorts of layout materials, which are currently handed in facility management within the universities land, can be expediently utilized through computerization of GIS, and thin study readily tries to determine the scheme to modify, complement, and manage the data.

레슬링선수의 체중감량시 체력변화에 관한 연구

박계순 울산대학교 1987 연구논문집 Vol.18 No.2

레슬링선수의 체중 감량시의 체력변화를 4%, 6%의 감량 후의 악력, 완력, 각력, 배근력, 사이드스텝, 윗몸일으키기, 체전굴, 500m달리기의 체력변화 측정을 한 결과 4%, 6%감량까지의 체력변화는 각 요소별로 다소의 차이는 있으나 큰 변화를 나타내고 있지 않다는 결론이 나왔다. The purpose of the study was to investigate the effect of the degree of body weight reduction on physical Fithness in Wrestlers. The population of interest for this study was restricted to student wrestlers at Korean National College of Physical Education. Complete data were obtained 6 subjects. The subjects were randomly selected from volunteers. The results were summerized as follows : 1. In case of Arm Strength and Grip strength were increased with 4% body weight reduction, but others were decreased with 6% body weight reduction. 2. In case of Leg strength were increased with 2% body weight reduction, but others were decreased with 4%, 6% body weight reduction. 3. In case of Back muscular strength were sustained normal condition with 2% body weight reduction, but others were decreased with 4%, 6% body weight reduction. 4. In case of vertical Jump an Side-steps were increased with 2% body weight reduction, but others were decreased 4%, 6% body weight reduction. 5.

Recently, GSIS is introduced in the various fields. Especially in hydrology, the useful of GSIS is emphasized to analyze parameters, which are necessary for the analysis of watershed. In this paper, to estimate the direct runoff volume, I used the SCS-CN method which was useful to calculate direct runoff volume in a watershed that was not observed. But because SCS-CN method must treat a great number of spatial data, if we use the GSIS, we can treat numbers of the data easily. GSIS databases is constructed by using the data which is related to soil type, landuse. And runoff curve number was estimated by means of these databases in the study area. Also, the area of covered each subbasin rainfall gauge station was estimated by thiessen polygon network technique. The direct runoff volume was calculated by these subbasin area to the rainfall gauge station. I knew, from this study, that using GSIS, I can calculate parameters needed in direct runoff volume analysis, fast, exactly.

Simulation model used in this research was developed from IAWPRC model. In this research, effect of SRT, feeding pattern and reactor configuration on intermittently aerated activated sludge system was evaluated by using computer simulation model. T-N removal was affected the SRT for the effeative T-N removal was 15day or longer. Feeding pattern in intermittently aerated activated sludge system was affect to the T-N removal. Feeding pattern which 100% loading to the first reactor was most effective for T-N removal. When multi-stage of two-stage or more was operated, COD and T-N in effluent removal was nearly the same.

申桂鍾 충주대 산업과학기술연구소 1999 産業科學論文集 Vol.7 No.2

A slope of terrain is very important factor in hydrological study, and it have a great influence on the results of modelling. A slope of extracted from DEM is affected by the cell size. thus, in this study we will analyze the effect occured in a slope of terrain by decision of cell size. We tried the change of grid size at 10m intervals and 100m intervals and analyed its effects. We found that the correlations between the average slope and size are Y=-3.836×IN(X)+31.9905 AND Y=-5.05597×1N(X)+39.5074
