This paper studied how much influence UTF coded data is given to HDB-3 operation efficiency. This paper applied the Hangul Jamo and Compatability Hangul Jamo in Unicode to compare to its UTF-8 coded data. As a result of study, When Unicode is reformatted to UTF-8 code, the data code run counter to the source coding rule was very much increased.

법적 의미로 "콘텐츠"란 "부호.문자.음성.음향 및 영상 등의 자료 또는 정보"(문화산업진흥기본법 제2조 제3호)이며, "문화적요소"란 "예술성.창의성 오락성.여가성.대중성"(문화산업진흥기본법 제2조 제1호 바목)을 말한다. 따라서 문화콘텐츠란 "문화적 요소가 체화된 부호.문자.음성.음향 및 영상 등의 자료 또는 정보"라고 할 수 있다. 이것이 '디지털'이라는 존재형식을 가지게 되면 "문화적 요소가 체화되어 경제적 부가가치를 창출하는 디지털콘텐츠"인 디지털문화콘텐츠가 된다(문화산업진홍기본법 제2조 제1호 제5호).(중략) 창출하는 디지털콘텐츠"인 디지털문화콘텐츠가 된다(문화산업진홍기본법 제2조 제1호 제5호).(중략).(중략)

In the recent years number of commercial off-line character recognition systems have been appeared in the Korean market. This paper describes a "self -organizing" data structure for representing a large dictionary which can be searched in real time and uses a practical amount of memory, and presents a study on the character correction for off-line printed sentence marks, Japanese, English, and Chinese character recognition. Self-organizing algorithm can be recommenced as particularly appropriate when we have reasons to suspect that the accessing probabilities for individual words will change with time and theme. The wrongly recognized characters generated by OCR systems are collected and analyzed Error types of English characters are reclassified and 0.5% errors are corrected using an English character confusion table with a self-organizing dictionary containing 25,145 English words. And also error types of Chinese characters are classified and 6.1% errors are corrected using a Chinese character confusion table with a self-organizing dictionary carrying 34,593 Chinese words.ese words.

1987년 완성음절형 한글 부호계(KS C 5601-1987)가 처음 제정된 이래 1992년 ISO 10646-BMP 또는 Unicode에 정보교환용 한글부호계를 반영하기 시작하여 2005년에 KS X 1005로 국제문자부호계를 제정하고 2007년 최종적으로 KS X 1026-1 제정을 통하여 정보교환용 한글 처리지침을 마련하는 것으로 옛한글처리를 완성하였다고 한다. 본 논문에서 훈민정음창제원리에 입각하여 옛한글처리 완성도에 대하여 정보교환용 한글처리의 한계와 문제점을 평가함으로써 한글처리의 효율성을 기하고자 한다.

This paper has studied about the scrambling occurrence frequency in UTF-8 coding system for Unicode Hangul Jamo codes. The scrambling methode applied in the study is HDB-3 in AMI line coding that is international transmission standard. In the study, the source coding rule was applied to analysis the scrambling occurrence. The quantity of the scrambling occurrence was calculated by the number of times and frequency rate of the scrambling occurrence in Hangul Jamo and Compatibity Hangul Jamo. In the case of Hangul Jamo, the number of times and frequency rate in Unicode and UTF-8 were 24times, 52% and 148times, 228% respectively. In the case of Compatibility Hangul Jamo, that were 10times, 14% and 83times, 131% respectively. As a result, when Hangul Jamo and Compatibility Hangul Jamo in UNICODE were transformed to UTF-8, the scrambling frequency rates were increased 340% and 851% respectively.

This paper discuss about DNA watermarking using coding DNA sequence (CDS) for the authentication, the privacy protection, or the prevention of illegal copy and mutation of DNA sequence and propose a DNA watermarking scheme with the mutation robustness and the animo acid preservation. The proposed scheme selects a number of codons at the regular singularity in coding regions for the embedding target and embeds the watermark for watermarked codons and original codons to be transcribed to the same amino acids. DNA base sequence is the string of 4 characters, {A,G,C,T} ({A,G,C,U} in RNA). We design the codon coding table suitable to watermarking signal processing and transform the codon sequence to integer numerical sequence by this table and re-transform this sequence to floating numerical sequence of circular angle. A codon consists of a consecutive of three bases and 64 codons are transcribed to one from 20 amino acids. We substitute the angle of selected codon to one among the angle range with the same animo acid, which is determined by the watermark bit and the angle difference of adjacent codons. From in silico experiment by using HEXA and ANG sequences, we verified that the proposed scheme is more robust to silent and missense mutations than the conventional scheme and preserve the amino acids of the watermarked codons.

The Compared to general sentences, the Equation uses a complex structure and various characters and symbols, so that it is not possible to input all the character sets by simply inputting a keyboard. Therefore, the editor is implemented in a text editor such as Hangul or Word. In order to express the Equation properly, it is necessary to have the learner information which can be meaningful to interpret the syntax. Even if a character is input, it can be represented by another expression depending on the relationship between the size and the position. In other words, the form of the expression is expressed as a tree model considering the relationship between characters and symbols such as the position and size to be expressed. As a field of character recognition application, a technique of recognizing characters or symbols(code) has been widely known, but a method of inputting and interpreting a Equation requires a more complicated analysis process than a general text. In this paper, we have implemented a Equation recognizer that recognizes characters in expressions and quickly analyzes the position and size of expressions.
