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.

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

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
