Ly Son (Quang Ngai province) and Phu Quy (Binh Thuan province) are two island districts in Vietnam that have similar natural characteristics;both are facing the issues of sustainable economic development. this research applied Man-Kendall model to estimate the trend of some socio-economic elements in these two island districts that have been collected during the period of 2002-2018. In general, socio-economic factors showed a tendency to increase recently. Ly Son island district has faster growth rate than that of Phu Quy because Phu Quy is farther from the mainland, more difficult to access and this island district does not own distinct local products. However, with the current development speed, Ly Son is facing several consequences such as insufficient water sources to meet the water demand and security instability due to the increasing number of visitors to the island. this research also proposed that, in order to sustainably develop the two island districts, there should be a specific structure for economic development orientation among sectors based on phased schedule. More importantly, tourism development planning should take capacity into consideration. Fishing practices should pay attention to methods and fishing equipment. Infrastructure investment for environmental protection as well as advocacy program to minimize the use of plastic bags should be done on a regular basis.

We present one-loop contributions for h→ℓℓγ with ℓ=νe,μ,τ,e,μ and e−e+→hγ in the U(1)_(B−L) extension of the standard model. In the phenomenological results, the signal strengths for h→ℓℓγ at the Large Hadron Collider and for e−e+→hγ at future lepton colliders are analyzed in the physical parameter space for both the vector and chiral B−L models. We found that the contributions from the neutral gauge boson Z′ to the signal strengths are rather small. Consequently, the effects will be difficult to probe at future colliders. However, the impacts of charged Higgs and CP-odd Higgs in the chiral B−L model on the signal strengths are significant and can be measured with the help of the initial polarization beams at future lepton colliders.

自从汉语传入越南之后就产生了大量的汉越词,“汉越词”是越南语的重要组成部分,占越南语词汇的60%以上。除了借用大量的汉语固有词汇外,越南人还根据语言表达需要,利用汉源语素创造出新词语,所谓的“越造今音汉越词”不断产生。越南语网络新闻媒体中的“越造今音汉越词”研究仍然处于起步阶段。本文以越南《青年报》电子版中的“双音节越造今音汉越词”为研究对象,以定量和定性两种研究方法相结合,对从《青年报》电子版中摘取的1035个双音节越造今音汉越词进行考察,从词语的语音、语义以及构词法等角度分析双音节越造今音汉越词的特点,以及它在越南网络新闻中的使用情况。第一章阐述选题意义、研究现状、研究方法与语料来源。第二章选用了越南《Báo thanh niên》(青年报)电子版作为语料来源,对《青年报》电子版中双音节越造今音汉越词进行详细考察。通过分析法以及统计法对报纸样本中的越造今音汉越词进行阐述、描述、统计及归类。从该报中的政治、经济、外交、社会等四大方面归类并总结出1035个常见的双音节越造今音汉越词。与此同时统计出每个词语的使用次数,整理出使用频率最高的一百个双音节越造今音汉越词。第三章对越南《青年报》电子版中的双音节越造今音汉越词的特点进行论述。对越南语中所出现的越造今音汉越词以及汉越词两者之间的异同点进行剖析,充分阐述两者的创意性。本章从语音、语义及构词方面进行阐述,指出《青年报》中的双音节越造今音汉越词在语音、语义及构词等方面的具体表现(如语音简化的作用;音与音之间的互相影响;越南的忌讳习俗;方言的影响;词义保留;词义扩大;词义转移)。第四章关于越南《青年报》电子版越造今音汉越词的使用建议。阐述该报中越造今音汉越词使用不当情况归类,如:滥用越造今音汉越词;使用晦涩难懂的词语;术语使用不恰当;任意缩写;该用纯越南语不用等,从而提出越造今音汉越词的使用建议。第五章是对全文的研究工作进行总结,总结其创新点,以及有必要进一步开展的工作。
