In this paper, we apply the K-theory to classify topological trivial fermionic phases which, nonetheless,host symmetry-protected non-trivial defects. An important implication of our work is that the existence of Majorana zero mode in the vortex core is neither a necessary nor a sufficient condition for the superconductor in question being topologically non-trivial.

Objectives: The study aimed to describe the quality of sleep and explore factors especially Sleep Hygiene Practices associated with sleep quality among pregnant women. Study design: This is a cross-sectional study. Methods: 119 healthy pregnant women in two central hospitals in Vietnam were participated in this study. The Pittsburgh Sleep Quality Index (PSQI) was employed to evaluate sleep quality and the Modified Sleep Hygiene Practices was used to describe sleeping practices among pregnant women. Results: The results showed that while 58.8% pregnant women had quite good sleep quality, 41.2% of pregnant women had mild to moderate quality sleep disturbance. The quality of sleep was better in second trimester, but then getting worst in the third trimester. Multipara experienced worse sleep quality than nullipara. Poor sleep quality had a positive correlation with unhealthy Sleep Hygiene Practices including using an uncomfortable bed (p < 0.05), going to bed with variable bedtime (p < 0.01), watching TV or making call in bed other than sleep (p < 0.05), going to sleep without sleep sensation (p < 0.001) and staying in bed even though it was difficult to fall asleep (p < 0.001). Conclusion: Pregnant women should be taken care of on sleep quality, especially in the first and third trimester as they experience more change in hormone and physiology. Sleep Hygiene Practices should be emphasized in health education for pregnant women.

Laos was once unique in Southeast Asia for its remarkably small overseas Chinese communities. Most of them fled this country when the communist forces seized power in 1975. Since Laos opened its economy in 1986, the Chinese in Laos have been able to develop in many areas. Especially, the visit of Premier LI Peng to Vientiane in 1990 marked a turning point in China-Laos relations. Unlike Cambodia, the reawakening of a Chinese community in Laos did not come from the Huaqiao, this arose from a new cycle of immigrants, who started pouring into northern Laos in the late 1990s at an unprecedented scale. Compared with other Southeast Asian nations, the Chinese in Laos are less in number and weaker in economic power. In this study, we focus on （1） Analysis the ways of the new Chinese immigrants in Laos; （2） Assess the role of new Chinese immigrants in the process of China increasing their influence in Laos and how Laos response to this issue; and （3） The trend of new Chinese immigrants in Laos in the near future. Firstly, the rapid of Chinese investment to Laos in the last two decades is the most important factor driving the Chinese migrants into this country. The first new Chinese immigrants arrived in the mid-1990s as workers or technicians on road construction projects and as part of the industrial cooperation between Yunnan and the northern provinces of Laos. Since the 2000s, China has been pouring aid and investment into Laos. Chinese companies are involved in almost all areas of this country＇s economy, from hydropower to mining, agriculture, service, and hospitality. The increasing of Chinese exports, investment, aids and Chinese contracted project constructions in Laos led to mass Chinese immigrants going to Laos to work in all the economic sectors which the Chinese are involved in this country. Most of them chose to stay on and started their own businesses. Secondly, the wave of new Chinese immigrants in Laos helps Chinese government to relieve the pressure of solvi

进入二十一世纪以来,随着科学技术的飞速发展,传统媒体以及新媒体的出现给受众的选择越来越多。大众与媒介之间有密切关系,不仅影响媒体发展的趋势,而会影响国家的政治、经济、社会的问题。本文从传播学的视角切入,通过选取越南河内市纸桥区的奕望后坊、观花坊与福寿县的福寿小镇、寿禄社为调查对象,采用定量与定性结合的研究方法,结合文献分析、数据统计分析等研究方法。根据越南民众与媒介接触情况、特点以及影响因素,进行探讨民众与报纸、广播、电视、网络等四大媒体接触的类型、内容、习惯等方面的异同点。本文采用SPSS 21.0统计分析软件对283个样本数据分为性别、年龄、职业、婚姻情况、受教育程度的变量进行描述分析和相关性分析。研究发现:(1)电视是越南民众最依赖的媒介渠道,此外,网络、报纸在提供信息方面仍然发挥着重要的作用,相比之下,广播的受众较小;(2)民众对电视传播的内容也是最可靠,其次是报纸,再次是广播,最后是网络;(3)男性人群比女性人群更倾向于媒介接触,年龄越大与媒介接触的需求越少,文职人员、大学生比农民、工人与媒介接触的程度更高,未婚人群与媒介接触多于已婚人群,受教育程度高人群比受教育程度低人群接触媒体更有选择;(4)在越南媒体背景下,民众与媒介接触有所变化。趋势和预测如下:男性人口增多是越南媒体发展的潜力,年轻人更倾向于新媒体,电视、报纸、广播都需要数字化才能生存下去,媒介受众逐渐转为网络媒体以及新媒体,受众与媒介接触的需求越来越高。

近年来越南经济发展速度平稳,对外开放程度逐渐加大,尤其是在基础设施建设领域吸引外资逐渐增多,越南承包工程市场逐渐也实行总承包管理模式。现阶段,中国企业在越南承包工程项目模式已经取得了一定的成果,但在具体实施过程中仍存在一系列问题,导致企业面临诸多风险。本文基于BOT项目基本理论和风险管理理论,通过探讨中国企业对越南基础设施项目投资的现状、越南承包项目工程市场发展模式以及BOT项目模式在越南承包工程市场的应用,以越南永新煤炭电厂BOT项目为案例,分析中国企业对越南投资BOT项目存在的风险管理问题,并提出了针对性的风险应对措施与建议。论文共分为四章：第一章是绪论部分,主要梳理了BOT项目模式风险管理以及中国企业对越南投资项目模式的相关研究综述,阐述了论文的写作背景与研究意义,另外还分析了中国企业对越南承包工程投资现状以及越南承包工程投资项目模式;第二章主要是对案例项目进行介绍以及对各个阶段BOT电厂项目的风险进行识别;第三章以BOT项目模式和风险管理理论为基础,对越南BOT电厂项目在不同阶段的风险及影响进行评估;第四章针对越南BOT电厂项目的上述风险问题,从风险规避和风险转移两个角度给出了相应的风险应对措施的建议,最后对整篇论文进行了概括与总结。
