본 논문에서는 대용량의 DNA 염기 배열의 정성 정보를 특징짓기 위한 새로운 가시화 방법을 제안한다. DNA 배열은 배열 자체가 방대한 양의 정보를 포함하고 있기 때문에 분석에 많은 어려움이 있다. 우리는 DNA 염기 배열들사이의 상사성 비교를 위해 DNA 염기 배열을 하나의 이미지 도메인으로 변환한다. 프로그램은 random walk plot으로 DNA 염기 배열을 가시화한 후에 k-convex hull로 단순화 시킨다. Random Walk plot은 염기배열을 평면상에 하나의 커브로 표현한다. k-convex hull은 walk plot으로부터 무의미한 부분을 제거함으로서 walk plot을 단순화한다. 이러한 방법은 유전공학자들에게 쉽게 DNA 배열의 특징을 인식하고 분류할 수 있는 직관을 제공한다. 실제 게놈 데이터로 실험한 결과는 논문에서 제안하는 방법이 긴 DNA 염기배열들 사이의 유사성 분석을 위해 좋은 가시화 도구임을 보여준다.

The direction of this study lies in exploring a schematic proposal for a historical walk over an area called 'West Village' located inside the old city wall of Seoul. The case study area is comparable to the historic 'North Village,' including historical assets such as the Kyunghi Royal Palace and Sajik-dan. Moreover, it has spectacular scenic spots surrounding Mt. Inwang and Baegundong Stream, although this has now been paved over for use as a road. This village maintained its fame as a hub of art through the early 20th century. The comprehensive approach of this study ranges from the historical and cultural to the ecological and visual. The results of this study can be summarized as follows. A themed walk would commemorate the great leader of national independence, Baegbeom Kim Ku, as well as the famous Korean style realistic landscape painting school under the leadership of Kyumjae Jeong Seon, a great artist of the Josun Dynasty. In addition, a scenic streamside walk would accentuate the surrounding panoramic vistas which were drawn by Kyumjae, while at the same time allowing the ecological system of Baegundong Stream to be uncovered and restored.

Oral and Maxillofacial defects is produced by trauma or cancer surgery. This defects have been shown functional loss such as mastication, swallowing, speech and psychosocial esthetic problem. Oral and Maxillofacial defects is reconstructed by the use of many flaps. However although previous flap surgery was done, additional soft tissue defects can be still remained. In this case, Walk-Up flap that is introduced by Marx RE in 1990 is recommended for successful reconstruction. We report Walk-Up flap for reconstruction of remained soft tissue defects of tongue S.C.C. After induction chemotherapy, tongue S.C.C. is excised surgically and reconstructed by use of PMMC flap. Post-op infection results in surrounding soft tissue defect with oro-facial fistula. We have experienced a case of Walk-up flap by use of PMMC flap for reconstruction with satisfactory result, so we report it with literature reviews.

An investigation was conducted to evaluate both the time required and the time allowed for persons to cross streets. Currently, the local municipality uses a standardized formula to determine the time allotted for 'WALK' signals to function allowing pedestrian traffic to cross thoroughfares. The formula to determine the 'Theoretical Time(in seconds)' is the width of the street(in meter) divided by 1.2m/s. The basis of the denominator is 'normal' walking speed. Initially, 3 locations were chosen to evaluate the time between the appearance of the 'WALK' signal and the appearance of the 'DON'T WALK'. The interval between the two signals was assumed to allow a person to begin crossing the street at the appearance of the 'WALK' signal and terminate their crossing at the appearance of the 'DON'T WALK' signal. Of the 3 locations, 2 locations(elementary?middle schools and general hospital areas), the duration of the 'WALK' signal were not properly set and therefore need more time for those who use these cross walks. Specific details regarding the crossing locations and validity of the standardized formula were also presented and discussed.

Purpose : This study achieved to search the effect of the circuit exercise and conventional exercise on walking ability(walking speed, endurance, dynamic balance, speed, endurance and pedestrian crossing) in chronic stroke. Methods : Since is diagnosed by stroke, to 30 chronic stroke patients who more than 1 year past the 15 circuit exercise group, the 15 conventional exercise group random the circuit exercise group applied circuit exercise 3th 8 weeks each week after neurological treatment because assigning and the conventional exercise group executed round trip walk exercise in parallel bar 3th 8 weeks each week after neurological treatment. The data of 25 patients who complete experimental course were statistically analysed. Results : The results of this dissertation were as following : 1) There were significantly increased after experimental of 10 meter walk test, 6 minutes walk test and Timed "Up and Go" test in circuit exercise group (p<.001). 2) There were significantly increased after experimental of 2, 4 and 6 lane road crossing mobility in Walking circuit exercise group(p<.01). 3) There were significantly differences after experimental of 10 meter walk test, 6 minutes walk test and Timed "Up and Go" test change quantity between circuit exercise group and conventional exercise group(p<.05). 4) There were correlations were found between the TUG test and 2, 4 and 6 lane road (2 lane road; r=.463, p<.01., 4 lane road; r=515, p<.01., 6lane road; r=.710, p<.01), and there were correlations were found between the 10 meter walk test and 6 minutes walk test(r=.595, p<.01), TUG test(r=.662, p<.01) and 6 lane road(r=.527, p<.01). Conclusion : Even if improvement of walk function through training consists in room, transfer of actuality pedestrian crossing is no change outside the room. Because it is much variable of the weather, seasonal factor, temperature, pedestrian number, state of underneath etc. outside the room. Then, in room after direction promotion of walk function to be promotion of walk function in actuality life and need development of connectable training method consider.

시간 측정 시 신호 발생 시점의 기준 펄스를 발생시키는데 사용되는 time pickoff 회로는 기준 펄스의 발생 시점이 입력 신호의 크기에 영향을 받는 time walk로 인해 측정 오차를 겪는다. 본 논문에서는 이와 같은 time walk를 감소시키기 위해 자동 이득 조절(AGC: Automatic Gain Control)을 이용한 time pickoff 방식을 제안한다. 자동 이득 조절부는 가변 증폭부와 바이어스부, 입력 신호의 크기를 측정하는 크기 획득부로 구성되며, 기준 펄스를 발생하는 비교기 앞에 위치한다. 그리고, 비교기 입력 신호의 크기를 거의 일정하게 조절함으로써, time walk 발생 원인을 최소화하고 기준 펄스 발생 시점의 변화를 감소시킨다. 제안한 time pickoff 회로의 동작은 SPICE 시뮬레이션과 실험을 통하여 확인하였다. 20dB의 dynamic range와 4 ns의 상승 시간을 가지는 입력 신호에 대해 측정된 time walk는 2 ns로, 일반적으로 널리 사용되는 leading edge discriminator에 비해 약 65% 개선된 성능을 보였다.
