The effects of C/N ratio of a nitrate-containing wastewater on nitrate removal performed by autohydrogenotrophic bacteria as well as on the morphological parameters of floc such as floc morphology, floc number distribution, mean particle size（MPS）, aspect ratio and transparency were examined in this study. The results showed that the nitrate reduction rate increased with increasing C/N ratio from 0.5 to 10 and that the nitrogen removal of up to 95% was found at the C/N ratios of higher than 5（between 0.5–10）. Besides, high C/N ratio values reflected a corresponding high nitrite accumulation after 12-hr operation, and a fast decreasing rate of nitrite in the rest of operational time. The final p H values increased with the C/N ratio increasing from 0.5 to 2.5, but decreased with the C/N ratio increasing from2.5 to 10. There were no significant changes in floc morphology with the MPSs ranging from35 to 40 μm. Small and medium-sized flocs were dominant in the sludge suspension, and the number of flocs increased with the increasing C/N ratios. Furthermore, the highest apparent frequency of 10% was observed at aspect ratios of 0.5 and 0.6, while the transparency of flocs changed from 0.1 to 0.7.

Groundwater is an important and readily available source of fresh water in the Mekong-Lancang River Basin. With a rapid population growth and increasing human activities, an increasing number of countries in the Mekong-Lancang River Basin are experiencing depleted and degraded groundwater supplies. In transboundary river basins, such as the Mekong-Lancang River, prioritizing the use of the shared aquifer by one riparian government may affect the opportunities of other riparian governments and lead to potential water conflicts between neighboring countries. To promote the sharing of strategies and information for the sustainable and equitable use of water resources of the shared basin, international collaborative workshops on groundwater resources have been organized for all Mekong-Lancang River countries. These workshops provide an opportunity to communicate and discuss nationally sensitive issues on groundwater by the associated countries, with topics covering multiple aspects of groundwater, such as the groundwater status in the basin, quality issues, water use conflicts, hydrological information gaps, management policies and capacity building for successful water resource management. Consensus has been reached by all countries on the importance of catchment-based groundwater management and the need for close communication among the countries. Strategies for managing transboundary aquifer issues must foster international collaboration based on the regional network, influence national networks and enhance the capacity to building maps and monitoring systems based on associated databases. The sustainability of water resources cannot be achieved without the integrated involvement and contributions by multiple countries and various stakeholders. Therefore, collaborative workshops provide a great opportunity to further our understanding of the hydrologic processes of the Mekong River Basin, share the benefits of the aquifer and provide a strategy and vision for sustain

Objective: To evaluate the efficacy of He-Ne laser in combination with topical clindamycin in the treatment of AV at 108 Military Central Hospital from Oct 2015 to Aug 2016. Subjects and Methods: 61 patients with AV were divided into 2 groups: Group 1: 31 patients were treated with He-Ne laser in combination with topical Clindamycin, Group 2: 30 patients were only treated with topical clindamycin. Laser HE-NE was applied 2 times/week for 6 weeks. Result: After 3 months of treatment Group 1: very good—51.6%, good—48.4%. Group 2: very good—30%, good—50% and moderate—20%. Conclusion: The combination of He-Ne laser with topical clindamycin shows more rapid clinical improvement compared to topical clindamycin alone in the treatment of mild and moderate AV.

Community-based tourism (CBT) is considered as one of the typical types of tourism towards sustainable development with three important goals such as bringing back economic benefits, protecting natural environment and preserving indigenous cultural values. Therefore, this paper analyzes the factors that affect community ecotourism development associated with environmental protection in emerging economies, including Vietnam, by the method of key and community tourism potential value assessment with 721 sample surveys. In this paper, we have applied to assess the key factors of tourism in Vietnam and other key points to have more comprehensive solutions to promote the development of community-based tourism with environmental protection. The article has used guest-based approach and method of assessing the key success factors. The results of researching factors to develop community tourist (impacting tourist community needs of tourists) by running Logit function have shown the great influence of factors such as: environmental protection (influence factor +3.585780, with a statistical significance of 99%), security and safety (+3.024816—statistical significance 99%) followed by infrastructure conditions & facilities for the community based tourism, the level of information etc… for your community based tourism needs. From the research results, we propose the following policy groups: 1) Developing guidelines for CBT, the first step as a basis for the development of community based tourism laws later;2) Policies related to the implementation of planning, development of key community tourist areas and destinations;3) Policies related to the development of community-based tourism associated with the protection of natural and cultural environments;4) Policies related to tourism management;coordinating monitoring of community tourism resource points;policies related to the local community in community tourism development;5) Policies related to human resource development;promo

在世界上,每个国家,每个民族都拥有自己独特的语言、文化艺术、社会、政治、经济等…在当今世界的发展中,保护传统文化元素,重要的是融合与国家的发展,是每个国家不可忽略的趋势的。越南有54个民族,广泛分布于全国北、中、南三个区域。在音乐方面而言,每一个民族,每一个地区都有自己鲜明的特色,与地理位置,语言和自己民族的政治和经济发展的程度密切相关。近年来在与世界音乐的融合趋势下,越南有很多音乐的研究人员,著名作曲家在越南以及世界各地已创造出诸多作品、研究等,标志着对于保护和发展越南少数民族的传统音乐的重视。被联合国教科文组织于2005.11.25确认为“人类口头与非物质文化遗产代表作”的“锣钲文化空间”是最好的证明。这是越南人民,尤其是对于中部西原的少数民族的骄傲。作为一名幸运的学生,本人非常自豪能在一所中国乃世界的著名音乐学院——上海音乐学院——学习。在学习和研究过程中,本人有机会接触到了很多中国著名作曲家的大型音乐作品比如陈其钢,谭盾,郭文景,温德青,叶国辉特别是本人专业指导徐坚强老师等,这让本人学会到很多专业知识,最重要的是如何把自己的民族传统音乐结合世界当代音乐语言。本人认为,对自己而言,如何研究把越南西原地区音乐语言结合世界当代音乐语言,并融入自己的个性是非常必要和重要的。本人的音乐的研究课题主要是围绕着“如何越南西原锣钲在西方当代音乐语言的运用”。其中在本人的作品里,本人将重点分析越南西原地区锣钲未开发或少见的表演性能。论文包括三章： 1.越南西原地区少数民族的文化、历史、音乐简介。西原音乐与西原地区民间艺术节、习俗、信仰、宗教密切相关,了解西原地区民歌及乐器。 2.研究越南西原锣钲乐器,越南西原锣钲在西方当代音乐创作如何应用。 3.作品并分析关于越南西原锣钲《山神叫声》作品（作品使用越南西原锣钲及西方交响乐团）。
