越南,对中国人来说也许并不陌生,因为它与中国毗邻,而且历史上两国关系源远流长。这些年来,随着中国经济快速地发展,中国人民生活水平也不断地提高。目前全球旅游趋势快速发展使中国人对旅游的需求也越来越高。在越南,广宁省位于越南东北部,与中国广西省交界。两国不仅具有地形优势而且风俗习惯拥有许多共同点,所以在东南亚的几个国家,越南就是中国人旅游目的地。五年来,根据广宁省游客市场的调查表明来自中国的游客是最稳定平衡的。中国人对越南旅游业,尤其是广宁省旅游业的发展来说已经作出了很大的贡献。

It is know that Multi-walled Carbon Nano Tubes (MWCNTs) are an excellent conduction nanomaterial while Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) is a conductive and transparent polymer. In this paper, we mix MWCNTs with PEDOT-PSS to create a new type of nanocomposite thin film which has both excellent conduction and transparency of each composition materials for applications in electronics and optoelectronics. The nanocomposite is synthesized by modifying MWCNTs in an acid solution then mix with PEDOT-PSS. The field emission scanning electron microscopy (FESEM) images of the fabricated thin film with 0.3 Wt% of MWCNTs show that the diameter and length of the MWCNTs are ca.10-30 nm and 300-500 nm, respectively. Electrical and optical properties of thin film are also investigated: the sheet resistance reaches the minimum value of 36.5 ?/□ with the transparency of ca.76% at the wave length of 600 nm. Furthermore, I-V characteristics of organic light emission diodes (OLEDs) made by the synthesized nanocomposite thin films are analyzed. The ITO/PEDOT-PSS: CNTs/PVK: MEH-PPV/Al multilayer OLED exhibits well improving performance with the work function of 0.8 V corresponding with the current of 0.4 mA while the ITO/PVK: MEH-PPV/Al simple OLED has the work function of 3 V and the current of only 0.01 mA.

古代历史上,越南由于许多原因而和东亚各国如中国、日本、朝鲜形成邦交关系。至20世纪扩展到东南亚各国,如马来西亚、新加坡,以及西方各国,如法国,从而形成邦交文学流派。邦交文学体裁主要为诗,并且其作者多为越南使节。因此,出使之路也可称作为诗歌之路。本文在对"邦交诗"、"赴使诗"、"接使诗"以及"送使诗"等进行重新定义的基础上,着重讨论作为一种广义概念的"邦交诗"这一特殊文学体裁,其所呈现出的越南古典文学在近十个世纪发展过程中的演变、成就及价值。

Background The metabolic syndrome (MS) is characterized by a specific clustering of risk factors, including dyslipidemia, central adiposity, systemic hypertension, insulin resistance, and dysglycemia. It is associated with an increased risk of developing cardiovascular disease (CVD). Accurate data on prevalence and characteristics of MS will facilitate the development of preventive strategies for CVD. Objective To estimate accurately the prevalence of MS among Vietnamese adults with the usual criteria or with the criteria modified for Asian populations. Design and methods We studied a representative, cross-sectional, population-based sample of 856 subjects (mean age 52.82 ± 16.36) classified in three age groups from 15-34 years, 35-54 years and ＞ 54 years of age, living in khanh Hoa Province, Viet Nam. MS was diagnosed according to the criteria defined by the Third Report of the National Cholesterol Education Program Expect Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel Ⅲ) (NCEP-ATP Ⅲ) and by the modified criteria for some Asian populations in which the waist circumference (WC) is considered abnormal if it is ＞ 90 cm for males and ＞ 80 cm for *** Using the NCEP-ATP Ⅲ criteria, the prevalence of MS in the studied population was 10.0％ (CI 95 ％:8.1-12.3). It was 2.4 ％ in the 15-34 age group (men 4.5％ and women 1.2％),5.2％ (men 6.3％,women 4.5％ ) in 35-54 age group and 15.8％ (men 9.7％, women 21.7％) in over 54 age group, respectively. And it was more common in women than in men (11.7％ vs 8.0％, P ＜0.001). Using 2001 population census data of the whole province over 15 years (695 218 habitants) we estimated that about 35 193 people suffered from the *** WC was the least common feature of MS (2.1％ for men and in 6.1％ for women).Overall,45.2 ％ of the studied population had one feature of MS, 23.1％ had two features, 8.2％ had three features, 1.6％ had four features, and 0.2％ had all five features.
