this study used the Binary Logistic regression model to estimate the willingness to pay (WTP) to reduce the use of plastic bags in the daily life of people in the Linh Nam ward. this study notes that households with higher incomes and higher levels of education tend to be more willing to pay. In addition, those who do not have access to information about the harmful effects of plastic bags and receive a higher proposed price often refuse to pay.

Cassava peel has a lot of nutrients which can be utilized as fertilizer in agriculture. However, high cellulose contents may cause difficulty for organic digestion and slow down the nutrient absorption for plants. this study aims to reach the microorganisms or their combination for biodegradating the cassava peel waste. The initial result shows that after 21 days the glucose concentration in all samples was the highest during experiment times. The reducing glucose produced in mg/mL by the selected bacteria was 9.32, higher than the selected fungie of 1.57 mg/mL. The percentage degradation of cassava peel weigh was the highest for fungi which was 52% of weigh, respectively. Meanwhile, bacteria only degradated about 31.6% after 4 weeks. However, the combination between bacteria and fungi provides the highest glucose concentration, 19.29 mg/mL and digests 62% of the mass cassava in experiment. this study suggests that biodegradation of agro-wastes in the environment to reduce biomass waste pollution is very promising.

The purpose of this study is to estimate the monetary value of the main environmental and external costs of Yali Hydropower Plant (YHPP) and to incorporate them into the financial viability indices of the plant, namely its net present value and electricity price. The results were found that if the electricity price is kept at its original level of 5.2 US cents/kWh to cover direct costs only, the net present value of the plant would be reduced to about 27% by incorporating environmental and external costs. Alternatively, the electricity price would have to be increased to 5.68 US cents/kWh in order to cover the full costs of YHPP and to maintain the original net present value. The main policy recommendations are: Government regulations should require that the financial analysis and appraisal of all future electricity sources include the full cost of these schemes, including not only direct costs but also environmental and external costs related to preventing or mitigating the environmental impact caused by them. An appropriate financial mechanism should be established to allocate the revenue from full cost electricity pricing to a fund to cover the environmental protection and compensation costs.

The Tan Rai Bauxite Project, which exploits a large bauxite mine in Lam Dong province, Vietnam has been in operation since 2012. In addition to the economic efficiency of the project, bauxite mining and processing uses a large area arable land and affect the regional environment. Remote sensing technology is increasingly widely used in many purposes in monitoring the changes of environment and resources, including land use change with high accuracy, giving managers more information to monitor the exploitation and use process of land resource. this study used a Change Vector Analysis (CVA) method of analysis on various remote sensing data sources to monitor the process of land exploitation and restoration of the Tan Rai Bauxite project. High-resolution remote sensing images were used as diverse as SPOT-5, VNREDSat-1, Google Earth from 2013 to 2019 to demonstrate the ability of the MCVA method to combine many other types of remote sensing images together. The results of fluctuation analysis were validated by 200 random points in the study area, and the accuracy of result is more than 90%. The results of land use change statistics were also compared with the annual data of Tan Rai Bauxite Factory. From this study, it can be concluded that the MCVA analysis method can quickly detect land use change areas and can combine many different image sources with a high accuracy. In addition, it also provides statistics of mining areas and restored areas, thereby assisting managers in monitoring the operation of the mine.

中越盂兰盆节的孝道思想对比研究

中越盂兰盆节的孝道思想对比研究

作者：阮氏玄（nguyen thi huyen）福建师范大学

学位级别：硕士

佛教孝道思想主要是“孝是报恩父母”,“报孝是实行作善业行为”,“孝是维持社会程序”。其内涵不仅是子女对父母孝顺,尊敬,责任,而且也是双方的责任,互惠,互敬,互爱。而这些思想很早就已传播到中国、越南,并随着其他佛教理论一起扎根... 详细信息

佛教孝道思想主要是“孝是报恩父母”,“报孝是实行作善业行为”,“孝是维持社会程序”。其内涵不仅是子女对父母孝顺,尊敬,责任,而且也是双方的责任,互惠,互敬,互爱。而这些思想很早就已传播到中国、越南,并随着其他佛教理论一起扎根繁衍。就越南的佛教传入而言,同样是出于同化本土文化与思想的目的。从广义上说,佛教思想具有其自身灵活性。所以,不管流传到哪个国家,为了适应当地文化、符合社会的需要,都有着自身的融合与变化,与佛教孝道思想一样。佛教盂兰盆节也是经历漫长的岁月的传承与演化。因此,与当地民族文化及思想观念存在许多相同与差异之处。中国是盂兰盆节的发源地,在这儿盂兰盆节本是代表中国佛教孝道思想。但是经过漫长时间,盂兰盆节被认为是解救亡身父母,祖先与饿鬼成为民间超度先人的节日。另外也被误解是中元节,鬼节。而越南虽然存在同样的节日形式,但是其节日内涵也衍变成首先跟现时父母报恩报孝,然后才是给亡身父母、祖先超度报孝与思念。目前,盂兰盆节成为越南的“报孝节日”。基于此,本文通过对佛教盂兰盆节的孝道思想、文化因素及其现代价值问题的研究,希望对当今社会孝道的发展。对人们在现代社会中如何行孝起到一定的积极作用。从此,笔者希望通过论述佛教孝道思想与分析和揭示了其孝道文化中的精华,探究其思想在中越国两国之间的传统文化和现代社会中的根基性作用。通过结合当今社会实践,开掘佛教孝道观念存在的价值。并希望一些想了解在巴利文中佛教的孝道思想与中越佛盂兰盆节教孝道思想的人能够分清楚两者思想的相同与差异的原因之处及以期对佛教研究有所裨益。

汉语副词“就”对越南学生习得汉语而言是汉语语法中比较特殊的一个类型。汉语副词“就”词义抽象、语法复杂、用法多变。此外,外国学生习得汉语时避免不了受到母语的干扰及不良影响,因此使用汉语副词“就”时会容易出现偏误句子。汉语副词“就”在不同的语境下语义也不相同,越南语中与“就”相对应的有以下六个词语:(?),其中有些词语的词义与“就”相同,有些词语的词义与“就”有差别。本论文以偏误分析理论为研究依据,为越南学生设计与汉语副词“就”相关的例子为研究的语料,在对汉语副词“就”与越南语副词“(?)”进行对比研究的基础上,通过问卷调查的方式分析越南学生习得汉语副词“就”的偏误类型,解释并提出偏误原因。最后针对偏误情况提出解决方案,进而提高越南学生使用汉语副词“就”的理解和运用能力,提高他们的汉语水平。
