The participants included 100 teachers of English and 100 non-English major students. The survey method, more specifically, the questionnaire was chosen as a data collection tool. The data were then processed using SPSS. The results showed that both the surveyed teachers and students believed that the classroom interactions involved talks between teachers and students (M = 4.8 and 4.83 for teachers and students, respectively). Besides, the teachers and students similarly considered that the classroom interactions in non-English large classes were limited because the students did not have many opportunities for speaking (M = 4.74 and M = 4.70 for both groups). However, the surveyed teachers tended to think that the students could learn from other peers through interactions (M = 4.39), whereas the mean score for this statement attained M = 4.0 for students' responses in the survey. Furthermore, the teachers reported that the interaction among the students led to the development in cognition and language learning (M = 3.76), but the students provided a lower appreciation of this issue (M = 3.0). Based on the findings, the study suggested implications for developing classroom interactions as well as future studies.

Ngoài ra, các hệ thống nuôi cấy khác nhau lần đầu tiên được sử dụng để sản xuất cây Dâu tây ở quy mô lớn. Kết quả nghiên cứu cho thấy, chồi in vitro có kích thước 3 cm nuôi cấy trên môi trường MS bổ sung 0,02 mg/L NAA, 1 g/L than hoạt tính, 30 g/L sucrose, 8 g/L agar và 0,5 mg/L AgNPs cho thời gian ra rễ sớm hơn khoảng 4 ngày và các chỉ tiêu sinh trưởng như chiều cao cây (5,60 cm), khối lượng tươi (242,67 mg), khối lượng khô (34,67 mg), số rễ/cây (6,67), chiều dài rễ (3,40 cm), SPAD (39,30 nmol/cm) cao hơn so với đối chứng sau 15 ngày nuôi cấy. Bên cạnh đó, bổ sung 0,5 mg/L AgNPs làm giảm hàm lượng khí ethylene trong bình nuôi cấy (0,06 ppm) so với đối chứng (0,15 ppm) sau 15 ngày nuôi cấy. Với mật độ 10 cây/bình nuôi cấy thủy tinh (250 mL) với 40 mL môi trường cho hiệu quả sinh...

This group consisted of 44 random interviewees who were auditors, lecturers, and banking staff, among others. Based on the results of this survey, the characteristics of the professional accounting group, including occupation, educational level, and work experience, etc., were collected. The accounting regulations for intangible assets in Vietnam in accordance with the guidelines of Vietnamese Accounting Standard (VAS) No. 04 (Intangible assets and other circulars) were then analyzed. Especially, these interviewees indicated three main obstacles of intangible assets accounting through this survey. First, the skills and knowledge of accounting staff are the most current weaknesses of intangible assets accounting. Following that, the slow integration of Vietnamese accounting regulations with the international accounting system for intangible assets i...

A Multimedia Model Based on Structured Media and Sub-Elements for Complex Multimedia Authoring and Presentation
International Journal of Software Engineering and Knowledge Engineering, 2002

However, the requirements of a model that could express richer scenarios for presentations are always a challenge. The work presented here proposes an extended model based on the concept of structured media and sub-elements that allows a finer granularity and a more semantic specification of significant events and locations inside media fragments. The new media fragments can be composed in multimedia scenarios through the specification of temporal, spatial and spatio-temporal relations. Moreover, we propose an abstract animation model that can be combined with the intra-media temporal structuration to specify animation effects in a flexible, not redundant and easy to maintain way. The underlying model is the Madeus model that is a flexible model based on the structural, interval, region and relative constraints. T...
