  • Writing a CAI program containing Chinese characters requires a common Chinese character code to share information for educational purposes. A Chinese character code setting needs to allow a mixed use of both vowel and stroke order, to represent Chinese characters in simplified Chinese as well as in Japanese version, and to have a conversion process for data exchange among different sets of Chinese codes. Waste in code area is expected when vowel order is used because heteronyms are recognized as different. However, using stroke order facilitates in data recovery preventing duplicate code generation, though it does not comply with the phonetic rule. We claim that the first and second level Chinese code area needs to be expanded as much as academic and industrial circles have demanded. Also, we assert that Unicode can be a temporary measure for an educational code system due to its interoperability, expandability, and expressivity of character sets.

  • In this paper, we propose online Chinese character learning machine with a depth camera, where a system presents a Chinese character on a screen and a user is supposed to draw the presented Chinese character by his or her hand gesture. We develop the hand tracking method and suggest the adjusted chain code to represent constituent strokes of a Chinese character. For hand tracking, a fingertip is detected and verified. The adjusted chain code is designed to contain the information on order and relative length of each constituent stroke as well as the information on the directional variation of sample points. Such information is very efficient for a real-time match process and checking incorrectly drawn parts of a stroke.

  • This study investigates Japanese-made Chinese Characters in JIS X 0212-1990(Code of the Su n.0, pplementary Japanese Graphic Character Set for Information Interchange). As a results of detailed investigation, it is found that the number of Japanese-made Chinese Characters in su n.0, pplementary set reaches to 69 characters. Among them, 29 characters are not listed even in the best known chinese character dictionary [대한화사전]. 30 characters are found in the chinese character dictionaries published in Korea, while 39 characters are not found in any of those dictionaries. The distinctive characteristic of Japanese-made Chinese characters is that those chinese characters are made in order to name the things, such as fishes, birds, trees, which do not have Chinese-made Chinese Characters.

  • Objectives : There are many secluded Chinese characters - so called Byeokja (僻字) in ancient classic literature, and Chinese characters that are not registered in Unicode and Variant characters (heterogeneous characters) that cannot be found in the current font sets often appear. In order to register all possible Chinese characters including such characters as units of information exchange, this study attempts to propose a method to encode the morphological information of Chinese characters according to certain rules. Methods : This study suggests the methods to encode the connection between the nodules constituting the Chinese character and the coordinates of the nodules. In addition to that, rules for expressing information about curves, expressions of aspect ratios of characters, rules for minimizing coordinate lines, and rules for expressing aggregation status of character components are added. Results : Through the proposed method, it is possible to generate codes of a certain length by extracting only information expressing the morphological configuration of characters. Conclusions : The method of character encoding proposed in this study can be used to distinguish variant characters with small variations in Byeokja, new Chinese characters and character strokes and to store and search them.

  • In this paper, a variable length block code for real time compression and decompression of hanguel and chinese character bit map font is proposed. The proposed code shows a good compression ratio in complete form of hangeul myoungjo and godik style and chinese batang and doddum style bit map font. Besides, a compression and decompression ASIC is designed and simulated on CAD. The 0.8 micron CMOS sea of gate is used to implement the ASIC in amount of 5,200 gates, and it runs at simple hardware and compress and decompress at 33M bit/sec at maximum, which is ideal for real time applications.

  • This research addresses to establish a systematic approach to design a standard Hangul code system for educational purposes in development of CAI courseware using Korean, English, and Chinese characters, which requires data exchanges and database construction. In this paper, types of Korean alphabetic code systems already in use, their representational environments and consonant/vowel order have been studied and analysed. This paper presents the requirements that the hangul code system for educational purpose needs to obtain. First, it should be able to represent all contemporary as well as ancient Korean alphabets. Second, character elements should be separable. Third, consonant/vowel order should be determined to easily retrieve and exchange data. Lastly, the code should maintain compatibility with other national codes and provide uniqueness of user-defined character codes.

  • This paper analyses the violation rate of CJK joint Chines character Unicode to the source code rule. In the paper, Chinese character 150ea in Chinese Unicode which have relatively a higher frequency in use of a character was chosen to study. The frequency rate in use of the 150ea characters is about 50% of the total frequency rate of the Chinese characters. The study was applied the AMI/HDB-3 line coding/scrambling and HDLC protocol, According to the analyses, the number of violated characters were 77ea of 150 ea, frequency rate in use 29%. Therefore, when the violated 77ea characters are replaced to the matched character codes to the source coding rule, the processing rate of the line coder can be improved about 37%.

  • The findings from this study are summarized as follows : 1. It is questionable to define the term "Hanja" as "the Chinese Character used independently or used along with Hangul. 2. It is found to be a problem that the validity and objectivity in the selection of Hanja are lacking. 3. It is also a problem that there is neither principles nor consistency in styling of characters. 4. The system of arrangement has problems, too. The adoption of arrangement of Hanja by its Korean pronunciation results in lots of errors and mistakes. Besides, mistaken strokes and radicals produced considerable errors in the arrangement of Hanja. 5. The omission of the abbreviated Hanja in the Code can be considered to neglect the current trend of increased use of them. 6. The issue concerned with the Japanese-origin Hanja is that several number of Hanja deemed unnecessary are included.y are included.

  • 본 논문에서는 보다 실용적인 온라인 한자인식기 개발을 위하여 한자 검정 능력 1급 쓰기 수준을 모두 포함하는 한자 필기 데이터로부터 16방향의 체인코드열과 부분획의 구조를 반영하는 구조코드열을 만들어 성능평가를 하였다. 인식 방법으로는 DP 매칭 방법과 HMM을 사용하여 2,362 종류의 한자에 대해 인식 실험을 하였다. 그 결과 체인코드열을 사용한 DP 매칭 방법에 의한 결과가 96.54%로 가장 높은 인식률을 보였으며, 구조코드열을 사용하여 HMM에 의한 인식실험 결과가 95.65%로 그 뒤를 이었다. 인식 속도면에서는 체인코드 보다 코드열의 길이가 짧은 구조코드열을 사용한 방법이 상대적으로 유리했고, 클래스 당 1개의 모델을 사용한 HMM에 의한 방법이 클래스 당 복수개의 모델을 사용한 DP 매칭 방법에 비해 모델의 개수가 훨씬 적기 때문에 속도 면에서 월등히 유리해 더 효율적인 인식 성능을 보인다는 결론을 내릴 수 있었다.
