Background: Since the identification of the cystic fibrosis transmembrane regulator (CFTR) gene in 1989, many polymorphisms have been identified in cystic fibrosis (CF) or CFTR-related disorders (CFTR-RDs) patients and still remain to be characterized at the molecular level. These polymorphisms are difficult to classify as pathogenic or non-disease causing because the polymorphisms are either located in the coding region, but are synonymous, or are found in the intronic regions. Here we investigated the potential impact of the c.743 + 40A > G polymorphism within CFTR intron 6 on the alternative splicing. Indeed, this variant has been observed frequently in our examined patients. Moreover, a family carrying this variant exhibited CFTR-RD phenotype. Methods: By denaturing high pressure liquid phase chromatography (DHPLC) and sequencing, thirty of 293 subjects French origin carried the c.743 + 40A > G variant. Of these, 16 patients were affected by CF or CFTR-RD. Wild-type sequences and mutant CFTR intron 6 and its boundaries were inserted into the pTBNdeI hybride minigene and expressed in three different cell lines. After RT-PCR analysis of mRNA using specific primers, sequences of the minigene transcripts were obtained. Results: No aberrant splicing was detected with minigene carrying c.743 + 40A > G variant in all transfected cell lines. However, an alternative splicing in the positive control was detected with a minigene carrying the c.1392G > T + 1G > T mutation: 5 nucleotides were deleted from mRNA sequences, indicating that used cell lines are appropriate for studying the splicing. Conclusion: Transient transfections of a minigene containing the c.743 + 40A > G polymorphism showed no splicing errors, and thus this intronic alteration was finally classified as non-pathogenic. As it is always associated with c.2562T > G and c.4389G > A, or TG12-7T poly-morphisms, further experiments are needed to determine the role of these complex alleles in disease pathogenesis.

沙特阿拉伯汉语学习者“把”字句习得观念和习得效果关系研究

作者：先锋（ALSHEHRI raed SHAYNAN）上海外国语大学

学位级别：硕士

现代汉语“把”字句的独特句式一直是对外汉语教学的重点和难点。近几年来,学习汉语的阿拉伯学生,特别是沙特学生越来越多。这对以阿拉伯语为母语的学生来说也是一个难点。本研究运用问卷调查、访谈以及测试各种具体研究方法,考察了阿... 详细信息

现代汉语“把”字句的独特句式一直是对外汉语教学的重点和难点。近几年来,学习汉语的阿拉伯学生,特别是沙特学生越来越多。这对以阿拉伯语为母语的学生来说也是一个难点。本研究运用问卷调查、访谈以及测试各种具体研究方法,考察了阿拉伯语母语沙特学习者“把”字句习得的难度观念,以及他们对“把”字句的难度认识和实际习得效果的关系,结果发现,学生觉得把字句的最大的难点是:(1)“把”字句结构较难,包括句子顺序、句式丰富、间接宾语太难等)。(2)学生不知道什么时候必须使用把字句什么时候可以不用,以及为什么要使用。由此可见,学生还没有真正理解和掌握“把”字句的语义和用法,学习者“把”字句整体习得效果不太好。此外,研究发现沙特阿拉伯学生对“把”字句整体习得效果和“把”字句的难度观念之间存在强负相关关系。大部分沙特学生认为学习“把”字句很难,他们还没习惯使用这种句型;他们觉得自己的中文水平还不够好,他们对“把”字句的掌握不够丰富,而且他们没有充分复习和练习使用“把”字句。我认为这些观念能够在一定程度影响到学习者“把”字句习得效果,并导致学习者回避使用“把”字句。根据测试的结果也知,学习者“把”字句整体习得效果不太好,学生对每类问题的错误率比较高,沙特阿拉伯学生们对“把”字句各方面的掌握程度还不够好。从现代汉语语法教学角度来看,我希望此文能够帮助了解沙特阿拉伯学生“把”字句习得难点,提高学生“把”字句习得的重难点意识,促进学习者“把”字句的有效产出,为阿拉伯国家的“把”字句教学提供启示。

Nowadays our world is faced with various environmental problems. These environmental problems are caused by the increasing pollution in the world, increasing production and consumption of material goods. These problems have serious consequences for human health and also have a major impact on natural ecosystems. This paper discussed sustainable green building in terms of key principles for sustainable building, strategies and guidelines for sustainable green building, and steps for an integrated approach to green design. The study also looked at the status of green building and sustainability, as well as green building materials in Palestine. The study suggested a checklist to help assess the condition of buildings in Palestine and the extent to which they respond to the principles of sustainable green buildings, thus, contributing to help new and existing buildings to adopt a sustainable green building approach, in order to achieve the goals of sustainable green construction in terms of saving energy and resources and reducing waste, therefore, participating in preserving the environment and improving the quality of life.

The main characteristics of potential smart cities in the future, smart citizens, smart energy, smart buildings, smart mobility, smart technology, smart healthcare, smart infrastructure, smart governance and education, and finally smart security are the aspects of smart cities. In the smart city, smart accessible infrastructure creates an inclusive environment for people with disabilities, in which they can integrate into the community and enjoy their civil, cultural, political, social and economic rights and entitlements. The aim of this study is to integrate disabled people into society so that they can actively participate in society and lead to a normal life. An integrated approach is needed to ensure that people with disabilities are not left alone. A combination of mainstreaming and targeted action is required for all interventions. People with disabilities have the same basic needs as everyone else: health protection and treatment, basic services, housing and income. Targeted intervention measures need to complement disability mainstreaming by addressing specific needs identified by general responses, including such interventions need not add materially to the overall cost, especially if the requirements of the maximum number of users are considered in the initial planning. This paper recommends how we can use an appropriate design checklist as a guide for our initial architectural concept and smart city planning to facilities reasonably accessible for people with disabilities in private and public buildings, making our cities smarter and more inclusive and helping to improve the quality of life for all people, especially people with disabilities.

讨论麦克斯韦等式下广义圆极化在手征性媒体中的不同的本构关系.在某类手征性媒体中广义圆极化波的场,与在非手征性媒体中麦克斯韦等式描述的同构关联有着相同的形式;但是不同的圆极化对应场的物理参数也不同.不管传播方向如何,这样的圆极化波(左或右)传播同等的波数.本文基于球面积分等式研究广义双各向同性物体的电磁散射特征.应用基层顶面等效性原理,能够把在均匀的双各向同性域中的电磁场用分布在它的边界面上的等量电磁流表示出来.
