The main objective of this study is to predict soil erosion in the Lattakia Governorate(W Syria) using the Water Erosion Prediction Project model(WEPP) and to compare the result with that of the RUSLE. Field survey and data collection were carried out, and 44 soil samples were analyzed. In addition, all the necessary input files were prepared for use in the WEPP model and RUSLE. Results show that more than of 80% of the locations studied experience slight to moderate erosion(less than 5 t/ha/y), whereas the rest of the locations experience severe soil erosion hazard. Moreover, the volume of runoff estimated by the WEPP model is in the range of 51 e321 mm, and the R~2 between the simulated soil erosion and the predicted runoff reached 0.68. Interestingly, the R~2 between the WEPP model and RUSLE is 0.56, which indicates a good correlation between the two models.

In round Ⅲ, the questionnaire was returned to the experts(n=17) until consensus was reached. Data from round Ⅱ and round Ⅲ were analyzed to produce mean score and final ***: The top 12 research priority lists were identified, which included subthemes and areas of possible investigations. All priorities were classified into three groups in the rank order, namely:(i) nursing management and leadership, which included(1) nursing care quality,(2) management and leadership of nurse managers,(3) nursing image,(4) professional nurse competency, and(5) human resource management;(ii) nursing education, which included(1) knowledge-specific domain,(2) the linkage between education and practice, and(3) nurse teacher workforce;and(iii) nursing service, which included(1) adult nursing concern,(2) patient safety,(3) public health nursing concern, and(4) quality of life of patients and ***: Consensus among experts was achiever, and the findings are considered as the basis of resources to the most essential research needs in Vietnam.

汉语目前是世界上人类使用最多的语言之一,因而这些年来人们学习汉语的需求越来越高。“如何教好汉语?”以及“如何学好汉语”这些问题一直被有关语言教学的研究部门重视并不停地探索以便找出最佳的答案。在越南特别是海防市,汉语被视为非常重要的外语之一,所以对该市的汉语教学现状进行调查研究是必要的。目前在海防市仅有海防大学设有汉语言专业,因此进行调查海防市的汉语教学现状也就是进行调查海防大学的汉语教学现状。根据实际调查的需要本文使用多样的调查方法以便各方面深入调查,尽量做出最为全面的调查内容。通过对越南海防大学汉语教学资料的收集、结合调查问卷和访谈的结果,本文深入研究及分析该校的实际情况,最终提出可行性的解决措施。除了摘要、附录、参考文件之外本文的主要研究内容分为六部分:第一章为绪论,这部分首先明确本文的选题理由和研究意义,其次对国内外有关越南汉语教学的研究成果进行综述,最后总结研究目标及方法;第二章对越南海防大学汉语教学的总体情况进行了概述;第三章对越南海防大学汉语教学的现状进行了调查,并对调查问卷进行了数据统计;第四章分析了越南海防大学目前汉语教学的现状;第五章对越南海防大学的教学提出了自己的一些见解和看法;第六章对全文研究的主要内容、创新之处以及文章的实践性进行了一个总结。本选题基于实际需要,在传统教育与新型教育大更替的阶段中,具有承上启下的作用。我希望这篇文章能够有助于改善越南的汉语教学情况,特别是海防大学汉语教学的现状。

Objective: To evaluate the impact of plant growth regulators including kinetin(KN),benzyl adenine and naphthalene acetic acid, yeast extract and casein hydrolyzate on biomass accumulation of Vietnamese ginseng Panax vietnamensis(P. vietnamensis) in cell suspension ***: Cell suspension cultures were established from friable calluses derived from leaves and petioles of 3-year-old in-vitro P. vietnamensis plants. The cell suspension cultures were grown in Murashige and Skoog basal media supplemented with various concentrations of KN, benzyl adenine, naphthalene acetic acid, and yeast extract and casein ***: All tested factors generated an increase in the cell biomass of P. vietnamensis in suspension culture, but the impact of each varies depended on the factor type, concentration, and incubation period. Addition of 2.0 mg/L KN resulted in the largest biomass increase after 24 d,(57.0 ± 0.9) and(3.1 ± 0.1) mg/m L fresh and dry weight, respectively,whereas addition of benzyl adenine or naphthalene acetic acid produced optimum levels of Panax cell biomass at 1.0 and 1.5 mg/L, respectively. Addition of the elicitor yeast extract led to a 1.4–2.4 fold increase in biomass of P. vietnamensis, while addition of casein hydrolyzate enhanced biomass accumulation 1.8–2.6 ***: The addition of each factor causes significant changes in biomass accumulation of P. vietnamensis. The largest biomass accumulation is from cultures grown in MS media containing 2.0 mg/L KN for 24 d. The outcome of the present study provides new insights into the optimal suspension culture conditions for studies on the in vitro cell biomass production of P. vietnamensis.
