In this paper we propose a new visualization technique to characterize qualitative information of a large DNA sequence. While a long DNA sequence has huge information, it is not easy to obtain genetic information from the DNA sequence. We transform DNA sequences into a polygon to compute their homology in image domain rather than text domain. Our program visualizes DNA sequences with colored random walk plots and simplify them k-convex hulls. A random walk plot represents DNA sequence as a curve in a plane. A k-convex hull simplifies a random work plot by removing some parts of its insignificant information. This technique gives a biologist an insight to detect and classify DNA sequences with easy. Experiments with real genome data proves our approach gives a good visual forms for long DNA sequences for homology analysis.

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.

Background: In the present study to investigate the immediate effects of standing position of the trunk stabilization exercise on Guillain-Barre syndrome patient's balance and gait abilities were examined. Design: Case report and conducted as a single-blind. Methods: Standing position of trunk stabilization exercise was conducted for five Guillain-Barre syndrome patient's who met the selection criteria were recruited. The subjects were conducted conservative exercise and trunk stabilization exercise. Conservative exercise was implemented for thirty min, five times for 8 weeks, and trunk stabilization exercise was implemented for 15 min. The participants' balance was measured via force plate (COP), functional reach test (FRT), timed up and go test (TUG), gait was measured using the 10 m walk test, and 6 minute walk test. Results: After training, the change values of the balance and gait ability in the subjects were significantly greater than pre-test. participants showed significant improvements in COP, FRT, TUG, 10 m walk test and 6 minute walk test pre and post the training (p<0.05). Conclusions: standing position of the trunk stabilization exercise was effective on Guillain-Barre syndrome patient's balance (COP, FRT, TUG) and gait (10 m walk test and 6 minute walk test) abilities were examined.

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.

A time-pickoff circuit used for time measurement suffers from a timing error due to the dependence of the generation time of a timing pulse on the size of the input signal, i.e., time walk. In this study, a time-pickoff method, which employs an automatic gain control (AGC) circuit, is proposed for reducing the timing error. The AGC circuit is added to the input of the comparator, and it renders the sizes of input signals of the comparator relatively uniform. The performance of the proposed time-pickoff method is analyzed using the SPICE simulation, and experiments are performed to confirm the analytical results. The measured time walk is reduced to 2.000 ns by 65% for input signals with a dynamic range of 20 dB as compared to a typical leading-edge discriminator.

The purpose of this study was to analyze of the rider postural alignments according to the fitting of stirrups lengths during walk of high level riders. Participants selected as subject were consisted of horse riders of high level (age: $47.66{\pm}3.51yrs$, height: $168.40{\pm}4.84cm$, body weight: $73.36{\pm}15.58kg$, low extremity length: $94.76{\pm}3.98cm$, career: $23.33{\pm}5.77yrs$) and walk with 3 types of stirrup lengths(ratio of low extremity 68.04%, 73.25%, 78.48%). The variables analyzed were consisted of the displacement of Y axis (center of mass, head, thigh, shank and foot), FR angle, LR angle, dynamic postural stability index (DPSI), coefficient of variation (CV%), and distance (X axis) of low extremity limb between right and left. The displacement of Y axis in COM, thigh, shank, foot limbs were not statistically significant, but movements of head showed greater distance of B type and C type than that of A type during 1 stride of walk. The FR and LR angle in trunk of horse rider, dynamic postural stability index and, coefficient of variation didn't show significant difference statistically according to the fitting of stirrup lengths. Also the distance (X axis) of low extremity in thigh and shank didn't show significant difference statistically in between right and left, but right and left foot showed greater distance in C type than that of B and A types during walk in horse back riding. The hip and ankle joint angle not statistically significant according to stirrups lengths, But knee joint angle showed more extended according to the increase of stirrups lengths during stance and swing phase in walk.
