In on-line character recognition, to segment input character is important. This paper proposes an internal character segmentation algorithm. The internal segmentation algorithm produces candidate words by considering possible combinations of Korean alphabets. In this process, we make use of projections of strokes onto the horizontal axis to remove ambiguities among candidate words. As a result of experiments, the internal segmentation algorithm shows better performance than external segmentation algorithm as the gap between sample characters becomes smaller.

외상성 슬관절 탈구 중 도수 정복되지 않는 경우는 매우 드물며 대개는 관혈적 정복술을 요한다. 본 증례는 도수 정복되지않는 슬관절 탈구에 대한 관절경적 치료 경험으로 자기공명 영상에서 정복을 방해하는 내측 인대 및 관절낭 구조물을 관찰하고 관절경 검사로 확인한 후 대퇴골 내측와가 완전히 관찰되고 관절이 정복 될 때까지 끼어있는 조직을 제거하였으며 인대 봉합이나 재건술은 시행하지 않았다. 술 후 약 4주간의 신전상태에서 고정 후 점진적인 관절운동 및 체중부하 보행을 허용하였다. 3년 추시 관찰에서 경도의 슬관절 불안정성은 있었으나 일상생활에 지장 없었으며 정상범위의 관절운동범위를 회복하였다. Irreducible knee dislocation is a rare injury and often need an open procedure with ligaments reconstruction. This report describes a case of arthroscopic treatment of a patient with traumatic knee dislocation unable to reduce in a closed method. MRI revealed incarceration of the medial collateral ligament and capsule in the medial compartment. And arthroscopic examination confirmed incarcerated medial capsuloligamentous structures which prevented the knee from reduction. Arthroscopic procedure without ligaments reconstruction was complete when the medial condyle was well visualized and the knee reduced. After 4 weeks of immobilization in extension, range of motion exercise and gradual increases in weight bearing was allowed. At the 3- year follow-up, mild laxity was remained but the patient did not have any discomfort of doing ADL activity and showed full range of motion of the knee.

This article examines some Korean traditional customs from Yangban class in Chosun dynasty such as ritual ceremonies for ancestors, entertainment for guests, scholastic pursuit and national exams (Guakeo), and disease and its treatments. It was in the Chosun dynasty when the word Yangban was used more generally rather than actually meaning or governing classes in the society. Therefore the world Yangban had been used for various purposes without conveying its clear meanings since this term was not regally regulated at the time. In addition, the society of the time changed very fast and its class system was not fixed within certain limits. In Chosun dynasty, the ritual ceremony was very common among yangbans as it represented devotion towards ones parents. However since the 19th century when standard of the yangban class became less strict, ceremonies tended to be more ostentatious and were full of artificial manners to show off the class superiorities. Yangban families often had many guests because yangbans formed some close relationships with other yangbans over academic pursuit, government services, and so on. Yangbans then should treat their guests with the best offerings in order to maintain their superior class level. Also if one neglected the importance of this hospitality, he or she was considered to be an outcast from the yangban class. Studies and exams are the two main concerns. The most important deed for them was reading. We can find evidence of the importance of reading for them from the books and journals handed down. From these the subjects had appeared most were disease and its treatment. Obviously, some easily curable disease for us today would have been serious at that time. Yangbans seem to have tried to treat the disease themselves. Or they separated these patients from their villages.
