Reflections on the Ecological Situations and Preservation of Tujia Language As An Endangered Language

Tujia Language is an endangered language.Language endangerment is deteriorating under the background of globalization.The preservation of endangered languages is more urgent and important than before.The best preservation of the endangered languages is to study them.The language ecology and preservation problem of Tujia Language will be investigated and discussed in this paper.

Brief Overview of Intelligent Education

Intelligent Education uses Al technology as a means in the education ecology to promote the automation and intelligence of education and teaching.It reshapes the education ecology,adding Al things to the traditional education ecology that dominated by teachers and students.Although IE technology is widely used,there is little discussion about a comprehensive overview of IE.The goal and connotation of IE is discussed.Meanwhile,the emotional,ethical,Al technology as well as supervision and management perspectives in IE are discussed too.The core goal of IE is putted forward that is human-oriented and individualized development of students is.Finally,the education ecology with dual-teacher collaborative in intelligence education was proposed.

Space Modeling Method for Ship Pipe Route Design

Ship pipe route design(SPRD)is one of the most complex and timeconsuming processes in ship detail design.Currently,there are many researches on the optimization of ship pipe routes,but there is still a lack of effective and convenient methods to build the pipe routing space.In order to solve this problem,a piping space modeling method for SPRD is proposed.This method is based on stereo lithographic(STL)file which is commonly used in data exchange,and it can convert the initial space model built in 3D-CAD software into the data model required by the pipe routing algorithms.For the application purpose,a piping space modeling utility(PSMU)is developed with Python and OpenGL,promoting the development of practical pipe routing system.Finally,the feasibility and practicability of the proposed method are verified by the experiment on the piping space of an actual ship fuel system.

Towards Positivity:A Large-Scale Diachronic Sentiment Analysis of the Humanities and Social Sciences in China

With its rising number of publications and expanding international collaborations,China's humanities and social sciences(HSS)research is displaying its potential for global prominence.Researchers have been exploring the development of China's HSS from different perspectives.However,the examinations from the perspective of sentiment analysis are scanty.Our aim is then to examine the sentiment features in Chinese HSS academic writing,by analyzing a large-scale corpus with over 275 million characters and with a time span from 2000 to 2020.Considering that most studies only focused on abstracts,we examined both the abstracts and the full texts,as well as a direct comparison between them.We found that Chinese HSS academic writing has evolved to be more positively biased in the past two decades,showing an upward trend in the use of positive words and a slight downward trend in the use of negative words.However,the upward trend of positive words in the full texts is not that clear,resembling a fluctuating pattern.Regarding the comparison,the abstracts are more likely to use positive words while the full texts tend to use more negative words.These phenomena can be explained with the social cognitive theory,in that they may be shaped by a joint force of the nature of human beings,the nature of language,the particular socio-cultural background in China and the features of the academic genre.
