This paper points out that the current Hengeul Morse Code is not reasonable in view of information theory. Based on the statistics on Hangeul investigated in 1973, this paper proposes a Hangeul Morse Code with care to handling two compound characters as source symbols and considers its effect on transmission speed. Thus the transmission speed of revised Hangeul Morse Coda is improved about 21% with compare to that of current one.

Hangul search functionality, including dictionary search is used in many Hangeul applications. Existing research of hangeul search method is the study of using hangeul syllable as a basic unit. However when you consider the characteristics of Hangul, the research of using hangeul character as a basic unit is needed. In this paper we propose the character based hangeul search method using the location-specific frequency information and verify the effectiveness of the proposed method through the experiments.

In this paper, we developed a Web App that operates in a mobile device. Also, we designed and developed an electronic dictionary of English words and sentences are expressed by English pronunciation with hangeul. The database using English words, Hangeul code with pictures, vocabulary definitions, speech sound files, and many sentences are created in this system. We developed the English learning system using HTML5 and m-Bizmaker software tools.

In this paper, we proposed an economical coding method to be applied for Hangeul character, the Korean letter, by utilizing three state transition graph. With this method, only about 3.5 biys are required in expressing a Hangeul character, which is more than 1 bit shorter than conventional codes so far introduced in order to realze extensive code compression. Hence this method will improve the rapidity and exanctitude and economy in processing Hangeul letter.

In this paper, a preliminary structural analysis of the information source of HANGEUL is performed statistically. And the results of the analysis are utilized to a KS HAHGEUL code, improving its transmission rate of 14%, on the basis of probability rankings of the fundamental HANGEUL elements. Forthermore Some problems about KS code, a coding method for the HAHGEUL information processing, as well as data entry are realized.

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.

UCS (=ISO/IEC 10646, =Unicode) will be used widely as globalization. If UCS is used for official purpose in Koreas, UCS solves a Problem in different hangeul code between South and North Korea. But, UCS is not a solution for problems in unequal order with the same character. IS0/1EC 146sl : 2000 (International String Ordering), which is a international standard for string ordering, defines a framework sorting all char-acter strings consisting multi-national scripts. Because the Common Template Table in ISO/IEC 14651 defines orders of characters, we can change orders of characters without changes of characters sequences in programs. Therefore, we can solve a ordering problem without unifying order of hangeul in South and North Korea. Functions related ISO/IEC 14651 are contained by system librarys in unix-based operating system such as Linux, Solaris and FreeBSD. We implement EUC-KR-based North Korean locale, which includes North Korean hangeul order, in Linux in order to use North Korean locale in South Korea. And we develop a program ordering strings with South and North Korean hangout order.

In this paper, a nibble RLE(Run Length Encoding) code for real time compression and decompression of Hanguel bit map font and printer data is proposed. The nibble RLE code shows good compression ratio in complete form Hangeul Myoungjo and Godik style bit map font and printer output bit map data. And two ASICs seperating compression and decompression are designed and simulated on CAD to verify the proposed code. The 0.8 micron CMOS Sea of Gate is used to implement the ASICs in amount of 2, 400 gates, and these are running at 25MHz. Therefore, the proposed code could be implemented with simple hardware and performs 100M bit/sec compression and decomression at maximum, it is good for real time applications.

HunMinJeongEum, meaning "the right sound to teach the people," was created in 1443 CE by King Sejong the Great, the fourth king of the Joseon Dynasty. In today's modern language, this letter, called Hangeul, is internationally recognized for its linguistic science. However, it is hard to find a comprehensive study on the fact that King Sejong himself created Hangeul, the Confucian perspective on natural disasters and democracy revealed in the process of writing, the independent efforts emphasized from a certain period, and the achievements of King Sejong, who shared the sorrow of the people and carried out national policies despite the extreme opposition of the nobility. Accordingly, I analyzed the consonants of HunMinJeongEum and looked at the essence of humanity and oriental philosophy (Yin-Yang Five Elements, Sangsu Philosophy, Hado). Surprisingly, different meanings from previous studies and interpretations were found, and King Sejong's "Da Vinci Code," which was left behind in the process of making the consonant, is reinterpreted and revealed. King Sejong's achievements were all connected as one. This is the root of democracy in the Republic of Korea today, and this is why King Sejong was selected as the most beloved and respected historical figure by the Korean people. This study will start with more people's understanding of the fundamental perception and philosophy of the world in Asia, including Korea, to reinterpret and reveal the hardships and great achievements experienced by a leader of a country in the process of creating korean alphabet, and to emphasize democracy, which is an important value for Asians and Westerners' mutual respect and co-prosperity.

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.
