Ancient Chinese characters, typically the ideographic characters on bones and bronze before Shang Dynasty(16th—11th century B.C.), are valuable culture legacy of history. However the recognition of Ancient Chinese characters has been the task of paleography experts for long. With the help of modern computer technique, everyone can expect to be able to recognize the characters and understand the ancient inscriptions. This research is aimed to help people recognize and understand those ancient Chinese characters by combining Chinese paleography theory and computer information processing technology. Based on the analysis of ancient character features, a method for structural character recognition is proposed. The important characteristics of strokes and basic components or radicals used in recognition are introduced in detail. A system was implemented based on above method to show the effectiveness of the method. 展开更多

The classification for handwritten Chinese character recognition can be viewed as a transformation in discrete vector space. In this paper, from the point of discrete vector space transformation, a new 4-corner codes classifier based on decision tree inductive learning algorithm ID3 for handwritten Chinese characters is presented. With a feature extraction controller, the classifier can reduce the number of extracted features and accelerate classification speed. Experimental results show that the 4-corner codes classifier performs well on both recognition accuracy and speed. 展开更多

The expanding role of the Chinese language in international communications has become increasingly prominent as China’s comprehensive national power continues to grow,leading to a significant rise in the number of Chinese language learners.Since online teaching is not limited by time and space,its application is widespread.For beginners in the Chinese language,the Chinese characters are both a priority and a challenge.The“Chinese Character Classification,”also known as the“Six Writings,”is the earliest systematic theory of Chinese character structures,and teaching Chinese characters in categories based on the“Chinese Character Classification”is a method that fits the cognition of beginners.In order to teach Chinese characters in a targeted approach,based on the collection and analysis of the common errors of Chinese characters among beginners,(1)this paper proposes that(a)the intuitive method can be applied to teach pictographic characters,indicative characters,and associative compound characters in online teaching;(b)the inductive-deductive method of“basic characters to new characters”can be applied for the teaching of pictophonetic characters and associative compound characters;(c)the learning of character patterns should be approached in a whole-part-whole process,while importance should be attached to the suggestion of the frequency effect with a view to facilitating the online learning of Chinese characters for beginners.The aim of this paper is to provide some practical implications for the online teaching of Chinese characters to foreigners. 展开更多

Idols and B-boys stages are fun, touching, and fantastic. Today, South Korean students are excited and enthusiastic about their colorful dance moves. The study is about creative educational methods that use K-pop music videos to learn the proverbs and old words that our ancestors learned to keep in mind and teach. K-pop lyrics are a rich reflection of the experiences of life and the world in which people are living today. Accordingly, this study can present new teaching and learning method examples that are used in class related to the old language associated with K-pop lyrics and can also introduce interesting class materials. 展开更多

Objective:To use high-frequency ultrasound to evaluate the efficacy ofα-lipoic acid combined with traditional Chinese medicine in the treatment of diabetic peripheral neuropathy(DPN),so as to provide a basis for clinical medication and evaluation of therapeutic effect.Methods:From December 2018 to December 2019,110 patients with DPN who met the inclusion and exclusion criteria were divided into observation group and control group according to different treatment plans.The control group was treated withα-lipoic acid,and the observation group was treated withα-lipoic acid combined with traditional Chinese medicine encapsulation treatment,and used high-frequency ultrasound,nerve conduction velocity and serological examination to comprehensively evaluate the effectiveness of the two treatment methods.Results:The mean amplitude of glycemic excursions(MAGE)value of the observation group and the control group after treatment was significantly lower than before treatment(P<0.05);After treatment,the SCV of the ulnar nerve,median nerve,and common peroneal nerve in the two groups was significantly faster than before treatment(P<0.05).Similar to SCV,the MCV of the three nerves measured after treatment in the two groups was significantly faster than before treatment(P<0.05).Compared between the groups after treatment,the three kinds of nerve SCV and MCV in the observation group were significantly faster than those in the control group(P<0.05).The cross-sectional area(CSA)value of the ulnar nerve,median nerve and common peroneal nerve in the observation group after treatment was significantly lower than before treatment(P<0.05).Compared with the control group after treatment,the three nerves CSA in the observation group was significantly lower than that in the control group(P<0.05).Abnormal ultrasound performance:The proportion of abnormal ultrasound performances of the ulnar nerve,median nerve,and common peroneal nerve in the observation group after treatment was significantly lower than before treatment(P<0.05).The composition ratio of internal echo reduction and ambiguity in the observation group after three nerve treatments was significantly lower than that in the control group after treatment(P<0.05).In the correlation analysis,the three kinds of nerve CSA before and after treatment were negatively correlated with SCV and amplitude(P<0.05),and positively correlated with latency(P<0.05).Conclusion:The combination ofα-lipoic acid and Chinese medicine encapsulation technology has a good effect on the treatment and repair of DPN nerve damage,and can be routinely applied in clinical treatment.High-frequency ultrasound can intuitively observe changes in peripheral nerves and can be used to evaluate the prognosis of DPN. 展开更多

Objectives of financial reporting are not immutable--they are influenced by a variety of factors, such as the economic, legal, political, and social environment in which financial reporting takes place. As the environmental contexts have changed in China since 1992, objectives of financial reporting have shown even more Chinese characters. In this paper, we focus on these special characters of objectives of financial reporting in China. In order to understand the objectives featured by Chinese characters, we are trying to find the hidden relationships between the objectives and environmental contexts. Our research shows that many researchers have already tried to establish objectives of financial reporting with Chinese characters, however current studies do have their limitations, and further studies should be done. 展开更多

Hanzi (Chinese characters) has a long history and affluent contents. To promote the popularity of historical and cultural knowledge of Chinese characters, an online program has been launched by Beihang University and Beijing Normal University to explain Chinese characters' original meanings and evolution processes with vivid and expressive animation videos. Currently, More than 1,000 videos can be accessed through the website “http://www.chinesecharacter.org/”. Besides these online resources, a human-computer interaction system is also proposed to simulate clerical changes of Chinese characters through computer morphing technology. What we want is to make the teaching and learning of Chinese characters more reasonable, more easily understandable and more interesting. 展开更多

This survey study aims to investigate the perceptions learners have of the character-learning strategies they employ when taking a web-based course in Chinese.The seven Likert-scale statements are included in the questionnaire to examine learners’opinions on the three character-learning strategies that are widely used in traditional campus courses.A total of 65 students who completed the beginner level‘Chinese Characters’web-based course at a university in Sweden completed the survey.The results suggest that students in web-based courses consider these three strategies to be just as helpful and effective as campus students;moreover,the more orthodox strategy-rote learning-is found to be the most popular among distance students.Furthermore,findings of this study provide insight into the limitations and advantages associated with a web-based course,and also the possible effect learners’age and gender may have on learning strategy preferences. 展开更多
