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.

한글 폰트는 서로 상반된 장단점을 가진 조합형 폰트와 완성형 폰트로 구분된다. 완성형 폰트는 조합형과 비교하여 우수한 품질을 가지지만 폰트 제작에 더 많은 시간과 노력을 요구한다. 특히 완성형 폰트는 폰트내의 중복된 자소들의 정보를 중복해서 저장하므로 폰트 저장에 필요한 공간이 더 많이 필요하다. 본 논문에서는 트루타입의 합성 글립(Composite Glyph)을 이용하여 이들 중복된 자소를 최소화한 완성형 폰트를 구성하였다. 실험 결과 생성된 완성형 트루타입 폰트는 기존 완성형 폰트와 유사한 고수준의 품질을 유지하면서, 샘체의 경우 기존 폰트의 57.6%, 명조체의 경우 73.0%의 저장공간을 절약할 수 있었다.Abstract Hangul fonts are classified into 2 categories, complete type and combination type which have their own strength and weakness. The complete type shows a high quality of fonts, while the combination type takes less time, efforts, and storage space to develop. Since the Hangul makes a syllable by combining consonants with vowels, the complete type has many duplicates and requires a large storage space to save them. We present a method that minimizes the duplicates of the complete type of the Hangul using the composite glyph of TrueType. New fonts had high quality and saved storage space, for example Sam saved 57.6% and Myungjo saved 73.0% compared to old.

고품위 입출력 장치의 급속한 발달과 전자 출판 시스템의 출현은 더 다양한 서체를 요구하게 되었다. 컴퓨터에서 사용되고 있는 한글 서체는 명조, 고딕체를 제외하고는 주로 장식용 폰트를 만들어 사용하고 있다. 본 논문에서는 Cubic B-Spline 곡선을 이용하여 다양한 필기체 폰트를 구현하였고, 필기체가 가지는 특성(날림의 정도, 글자의 기울이기 정도, 각 음소의 크기, 각 글자의 크기의 균일성 등)에 따라 인자를 부여하여 개별화되고 사실적인 폰트를 생성하였다. 각 인자의 조합은 암호화되어 각 개인의 폰트로 부여된다. 즉, 개인의 고유 폰트는 폰트 암호(password)로 부여되고, 제어인자는 폰트암호의 해쉬값에 의해 선택되며, 사용자들로부터 이 제어인자들을 숨기게 되면 각 사용자들의 폰트는 유일하고, 안전하게 되므로, 일정정도의 안정성이 보장된다고 보여진다. 그리고 본 연구에서 구현된 폰트는 한글 필기체 문자인식의 정도를 측정하는 다양한 데이타를 제공하는 데에도 의미가 있다.

This paper written by Choi Bu based on "Piaohailu". This book consists of 3 volumes and it is his travelogue; Choi Bu has departed from Jeju Island to Naju, Jeolla province in the end of 1487, but it drifted on his way, so arrived to Zhejiang Province, China(Mid-Ming Dynasty) in early 1488. In this place, he interrogated with a reason for Japan pirates, but he released soon. And his waterway journey from Hangzhou to Beijing, he had received the award in Beijing which is the grace of the Emperor;and his land route journey from Beijing through Liaodong to Uiju, Pingan Province. Afterwards, this book had been translated in Japanese, English etc; and it had been awarded an alias of 'Chaoxian's Marco Polo'.From the description of the characters in the Mid-Ming Dynasty in the work of Pyohae-rok, the essay makes a study on the knowledge of ancient Korean scholars to China, and looks at the different social and political aspects and characteristics of the Ming Dynasty from the eyes of Korean scholars. It summarizes that when we face history squarely, it is important to refer to and draw on the foreign works recorded by ancient Korean scholars.

Cui Pu Korea period official, 1487 AD to Jeju Island to perform official duties, after the death of his father, in 1488 leap on the third day of the first month home, unfortunately encountered a storm on the way, and drifting in the sea nearly half a month later, finally landed in the "Datang state Zhejiang Taizhou Prefecture near the Hai county border" (now Sanmen county). Cui Pu traveled overland from Taizhou to Hangzhou, then via Hangzhou, by boat along the Beijing-Hangzhou Grand Canal to Beijing, and then by land from Beijing through Shanhaiguan Pass, through the Yalu River back to his motherland. We have pieced together the distance he traveled, the current situation of the places he passed through. He also hopes to make a new record of the changes of these sites by revisiting the important sites he has walked. This study explores Cui Pu's footprints and reviews the history by comparing the ancient and modern places he passed through.

The application of OCR moves from traditional formatted documents to the web document and natural scene images. It is usual that the new applications use not only standard fonts of Myungjo and Godic but also various fonts. The conventional databases which have mainly been constructed with standard fonts have limitations in applying to the new applications. In this paper, we generate 243 image samples for each of 2350 Hangul character classes which differs in font size, quality, and resolution. Additionally each sample was varied according to binarization threshold and rotational transformation. Through this process 2187 samples were generated for each character class. Totally 5,139,450 samples constitutes the printed Hangul character database called the PHD08. In addition, we present the characteristics and recognition performance by an commercial OCR software.

This study used a method of comparing and analyzing various editions of Jeokcheonsu, and aims to confirm why different views have arisen on commentaries that differ according to the perspective of one original text, which interpretation is more valid among them. It is not easy to grasp the theories of Myeongri because Jeokcheonsu is composed of the sentences of Si-bu with being well refined and having hidden meaning. Various perspectives makes the people more confused in reading commentaries. Lim Cheol-cho make additional annotations and try to subdivide the contents of Jeokcheonsu and classify them with quoting lots of 512 exemplifications in Ming Dynasty, and it is his great contribution to the Myeongri theory. The perspective that 'Eokbu Theory' is core contents of Myeongri theory in the first half of Jeokcheonsu is predominate. The sentence that 'Eokbu Theory' is mentioned for the first time is 'Cheayong, and we can quote 'Jeongsin', 'Soewang' and 'Junghwa' as a sentence paired together.'Eokbu Theory' of Jeokcheonsu is discussed continuously in the 'Gangyou' 'Junggwa' of Myeongri particulars which is connected in the middle of Jeokcheonsu.

Cui Bu (1454~1504 BC), named Yuanyuan, named Jinnan. Served as the deputy manager of the Korean King Chosun Hongwenguan (fifth grade official). In 1487, on the way to Jeju Island to perform official duties, because his father died, he went home from the funeral on the third day of the first lunar month in 1488, but was unfortunately on the way. Encountered a storm, and drifting at sea for nearly half a month, he landed at the "Linhai County Boundary of Taizhou Prefecture, Zhejiang Province, Datang Kingdom" (now Sanmen County). Later, Cui Bu went to Hangzhou by land near Taizhou, where he landed, then via Hangzhou, took a boat along the Beijing-Hangzhou Grand Canal to Beijing, and from Beijing by land through Shanhaiguan, and returned to his country via the Yalu River. Cui Bu stayed in China for four and a half months, 136 days, and traveled nearly 9,000 miles. After returning to China, he wrote the book "Piaohailu" in Chinese. This diary-style book has a total of more than 50,000 characters, covering politics, military, economics, culture, transportation, and local customs in the early years of Hongzhi in the Ming Dynasty. The situation is an important document for studying China's Ming Dynasty coastal defense, political system, justice, canals, cities, topography, and folklore.
