Smoothing Algorithm을 이용한 DNA 코드 최적화
윤문식(Mun-Sik Yun),한치근(Chi-Geun Han) 한국정보과학회 2003 한국정보과학회 학술발표논문집 Vol.30 No.2Ⅰ
DNA(Deoxyribo Nucleic Acid)컴퓨팅은 생체분자를 계산의 도구로 이용하는 새로운 계산 방법으로 DNA 정보 저장능력과 DNA의 상보적인 관계를 이용하여 연산을 수행하는 방법이다. 최근에 DNA 분자들이 갖는 강력한 병렬성을 이용하여 NP-Complete 문제에 적용하는 연구가 많이 시도 되고 있다. Adleman이 DNA 컴퓨팅을 이용해 해결한 HPP(Hamilton Path Problem)와는 달리 TSP(Traveling Salesman Problem)는 간선에 가중치가 추가되었기 때문에 DNA 염기배열로 표현하기가 어렵고 또한 염기배열의 길이를 줄이기 위래 고정길이 염기배열을 사용할 경우 가중치가 커지면 효율적이지 못하다. 본 논문에서는 스무딩 알고리즘(Smoothing algorithm)을 사용하여 간선의 가중치를 일정한 비율로 줄인 다음 유전자 알고리즘을 사용하여 최적의 염기배열을 찾는 방법을 제안하였다.

Objectives: The Purpose of this study is to compare X-ray Cobb`s angle and clinical symptoms with a 13-years-old girl who has C-T spine 12。, T-spine 20。, T-L spine 33。 with X-ray Cobb`s angle. Methods: Clinical datas were compared visual observation (Included IBS 2000) and Cobb`s angle with X-ray Full spine A.P. and Lateral view. Results: Patient`s chief complain is scoliotic position, high left shoulder, left rib hump, hip right projection and walking disorder. Most symptoms and Cobb`s angle(C-T spine 12。→9。, T spine 20。→17。, T-L spine 33。→25。) decreased. Conclusions: We experienced improvement of symptoms to this patient by Chuna therapy.

Objectives : The aim of this study was to investigate the effect of warming acupuncture therapy on patients who had suffered from low back pain. Methods : The 42 persons who had hospitalized in Jaseng hospital were randomized into two groups. We treated 22 persons by warming acupuncture on every other day. The others were treated by only traditional acupuncture therapy alone. VAS(Visual Analogue Scale), ODI(Oswestry Disability Index) and the angle of SLR(Straight Leg Raising test) were measured on each week from admission for four weeks. Results : 1. Sample group showed significantly more improvement than control group at 3 weeks in ODI score. 2. Sample group showed significantly more improvement than control group at 2 weeks in VAS score. 3. The angle of SLR test was not significantly different between two groups, but there was a tendency of increasing on sample group. Conclusions : According to above results, warming acupuncture therapy was more effective on the treatment of low back pain than general oriental medical therapy without it.
