  • AMI / HDB-3 method used a scrambling technique is used primarily for long distance data transmission line encoding. In this paper, information communication code standard (KS X 1001; 2014 confirmation), as defined in Hangul Character Code HDLC Flag bit or character stuffing at the data link layer and physical layer with respect to the code set for Hangul AMI / HDB-3 the code set for the new system to increase the data transmission efficiency Hangul consonant and vowel tables presented in terms of scrambling. The result of the existing system and the code set ($4{\times}4$) bit source coding rules for comparing the frequency of use Hangul consonant and vowel tables and statistics showed that about 22.01% of the data processing efficiency is improved.

  • The operator LIKE of the database language SQL is a string pattern search operator. By providing the string pattern, the operator can identify column values that match with the string pattern. As a phonetic symbol, each Korean syllable is composed either of a leading sound and a medial sound or of a leading sound, a medial sound, and a trailing sound. As a search pattern of Korean syllables of the operator LIKE, in addition to the traditional Korean search pattern, this paper proposes a new search pattern that is based on leading sounds and medial sounds of Korean. With the new Korean search pattern, Korean syllables having specific leading sounds, specific medial sounds, or both specific leading sounds and medial sounds can be found. Formulating predicates equivalent with the new Korean search pattern by way of existing SQL operators is cumbersome and might cause the portability problem of applications depending on the underlying character set of the DBMS. This paper presents algorithms for the execution of the operator LIKE considering the new Korean search pattern based on the characters that are represented in KS X 1001, which is a Korean standard code for information interchange of Korean and Chinese.

  • This paper propose the rule of coding for the characters and symbol, etc which are used in computer, information devices, etc. When they use the rule of coding, they may improve the efficiency of transmission in data communications by reducing the number of scrambling during the line coding in the coder in the transmitter. The paper considered the codes of two bytes(16 bits) of 4bits column ${\times}$ 4bits rows. In the paper, we applied the code system of Roman characters in KS X 1001.

  • In this paper, We investigate the search patterns that are applied to the character based word search and make the search algorithm. We used to various hangout coded set that are KS X 1001 hangeul coded set and unicode 3.0 for the character based word search algorithm. In each case, We study of efficiency of algorithms that are related to hangeul coded set.

  • 한글을 인식하기 위한 전처리 방법으로 흔히 모음의 종류 및 자음과의 결합 정도에 따라 6가지 유형으로 분류하는 방법을 많이 사용하고 있다. 간 논문에서는 이러한 한글 문자를 인식하기 위한 전처리 과정으로써 한글의 유형을 분류하는 방법에 대한 연구로 계층적인 신경회로망을 도입하여 빠르고 신뢰성 있는 분류 방법을 제안한다. 실험에 사용된 글자는 KS X 1001(KS C 5601) 완성형 글자 2,350개에 대한 굴림, 바탕, 돋움, 궁서 글꼴로 총 9400개의 이미지 파일을 사용하였으며. 이 중 일부는 훈련에 사용하고 나머지는 분류를 위한 테스트 데이터로 사용한 결과 약 94%의 유형 분류율과 개별 패턴을 5.67ms에 분류하는 빠른 분류 속도를 나타내었다.

  • This paper is studied the Korean language to optimize the Hangul character coding for information processing in information terminal device and transmission in network. The paper analyzed Hangul character in Korean language and use frequency of each character. The paper also compared the analysis result to Hangul characters which are coded in standard in Korean character and Unicode. This study referred "Modern Korean Use Frequency Rate Survey Result" issued by The National Institute of the Korean Language. There are total 58,437 Korean words in the report. As a result of this paper, the Korean word 58,437ea are consisted of Hangul character total 1,540ea. The highest use frequency character is "다" and its use frequency to total use frequency rate is 15%. The lowest use character is "휫"and its use frequency to total use frequency rate is 0.00003%. The number of analyzed Hangul character 1,540 is less 7.2 times and 1.5 times than Korean and Unicode standard respectively.
