Body weight support treadmill training is a new and promising therapy in gait rehabilitation of patients with hemiplegia. The purpose of this study was to identify the effects of body weight support treadmill training on gait and standing balance in patients with hemiplegia. Eighteen patients with hemiplegia participated in the study. A 10 m-timed walk test, measurements of step length and standing balance score were administered. Intervention consisted of body weight support treadmill training five times a week for 2 weeks. The data were analyzed by paired t-test. Body weight support treadmill training scoring of standing balance, step length and 10 m-timed walk test showed a definite improvement. Body weight support treadmill training offers the advantages of task-oriented training with numerous repetitions of a supervised gait pattern. The outcomes suggest that patients with hemiplegia can improve their gait ability and standing balance through body weight support treadmill training.

The aim of this study was to improve the vertical motion performance of floating marina structures and to optimize the shapes of the structures for the Korea coastal environment. The floating body is connected to a plate-shaped submerged body through a connecting line under the water that has a stiff spring that serves to reduce the heave response. This system, which has two degrees of freedom, was modelled to analyze the interaction between the floating body and the submerged body. The vertical motion of the two-body system was compared with the motion of a single body to verify that the system could perform as an optimized model.

Purpose: This study was done to compare of adult body composition and body image before and after regular exercise program at a sports center. Method: The participants were 32 adults who were beginning regular exercise at a sports center in D city. The body composition was measured by body weight, soft lean mass, fat mass, percent body fat, fat distribution, degree of obesity and BMI, using the Inbody 3.0. Body image. Data were collected using structured questionnaires and analyzed using paired t-test. Results: 1. Significant improvement was shown in body composition. 2. The score for body image increased after the program, but the change was not statistically significant. Conclusion: The short-term exercise program was very effective in improving body composition, but changes in the evaluation of body image need long-term exercise. Also, we were concluded that it is very important to consider preference level when evaluating body composition and body image.

This paper addresses a systematic way of understanding the transfer characteristics of whole-body vibration due to the external excitation. Amirouche's and Tamaoki's models are considered, whose analysis shows a new result that resonant frequencies related to the head vibration are well coincided with those of the body. This point reveals that the improvement of the ride quality of passenger cars can be achieved by isolating only external vibration components transfered to the body. Finally, this paper points out the limitation of previous whole-body vibration models, which gives the motivations of setting up more 'practical and generalized' whole-body vibration models of interests in this study.

본 논문은 가시화 기반 LBVH(Linear Bounding Volume Hierarchy))을 이용한 빠른 GPU기반 N-body 충돌 체크 알고리즘을 제안한다. 본 알고리즘은 움직이는 n-body 개체에 대한 수정된 모튼코드(Morton code)를 이용하며, 이 모튼코드는, 일반적으로 사용되는 개체의 위치 정보뿐 아니라 이 개체가 스크린상에 차지하는 가시화 영역 정보를 이용하기 때문에, 카메라의 위치 및 방향에 따라 화면상에 차지하는 영역이 작은 개체에 대한 빠른 GPU기반 정렬(sorting)이 가능하게 된다. 실험을 통해, 본 논문에서 제안하는 방법이 기존 방법보다 15%이상 성능 향상이 있음을 알게 되었다

1997년부터 2001년까지 (사)한국종축개량협회의 전국한우능력평가대회에 출품된 642두의 거세한우의 도축 전까지 4회에 걸쳐 주요 10개 부위의 체형 측정치를 조사하여 주성분 분석을 이용하여 체형을 분류하였으며, 각 체형 측정치의 주성분 지수와 도체 형질과의 상관관계를 분석하였으며, 그 결과를 요약하면 다음과 같다. 1. 1차, 2차, 3차 및 4차 체형 측정치의 principal component(이하 P.C) 1의 분산은 각각 7.610, 8.297, 7.269 및 5.739로서 전체분산 중 76.0%, 83.0%, 72.7% 및 57.4%를 나타낼 수 있었고, P.C 1, P.C 2, P.C 3의 합은 전체분산 중 각각 86.69%, 90.49%, 84.62% 및 77.26%를 나타났다. 2. 각 차수별 체형 측정치의 P.C 1의 모든 계수가 양(+)이어서 일반적으로 좋은 체구의 크기를 나타내었으며, 체구의 크기에 가장 크게 영향을 미치는 형질은 흉심(0.328${\sim}$0.339)과 요각폭(0.325${\sim}$0.341)이였다. 또한 P.C 2, P.C 3 및 P.C 4는 각 차수별로 다양하게 나타났다. 3. 1차, 2차, 3차 및 4차 체형 측정치의 주성분 지수들과 도체형질간의 상관계수 추정에서 대부분의 분산을 차지하는 P.C 1은 도체중(0.539${\sim}$0.755), 일당증체량(0.256${\sim}$0.564), 등지방두께(0.227${\sim}$0.280) 및 배최장근단면적(0.187 ${\sim}$0.344)간에 정(+)의 상관을 보였으며, 육량지수(－0.246${\sim}$－0.110)와는 부(－)의 상관을 보였고, 근내지방도(0.066${\sim}$0.099)와는 대부분 유의적인 상관을 보이지 않거나 낮은 상관을 보였고, P.C 2, P.C 3 및 P.C 4는 주성분 지수들의 값에 따라 도체형질과 다양한 상관관계를 보였다. 단일 체형형질과 도체형질간의 상관 그리고 P.C 1의 주성분 지수와 도체 형질과의 상관간에는 큰 차이가 없었다.

The purpose of this study was to verify the effect on improvement of muscle strength unbalance according to load deviation protocol during whole body vibration exercise. Seventeen female volunteers (age $22{\pm}3$ years, height $160{\pm}4.9$ cm, weight $49{\pm}.8$ kg) participated in this experiment. The subjects performed squat exercise in WBV platform. Exercise were performed five set a day including 15 time a set, three days a week, and during 4 weeks. Vibration stimulus was 25Hz as frequency and intensity was dominant leg 1mm and non-dominant leg 4mm. The results in WBV group showed that the differences of peak torque in 16% were getting decreasing significantly after 4 weeks from 16.2% to 5.2%. This result means that WBV with load deviation protocol could provide muscle strength exercise for muscle strength balance. Our study found out that WBV of load deviation protocol could provide muscle strength exercise for improving muscle imbalance.

Objectives: We would like to report improvement in symptoms after performing Korean Medicine treatment including Gamiboik-tang administration to patient with presbystasis that lasts for more than a decade. Methods: An 83-year-old male patient diagnosed with presbystasis was administered Gamiboik-tang for 4 weeks and acupuncture was performed. The degree of improvement is evaluated based on the body balance test and the patient's subjective symptom change. Results: Both the body balance test and the patient's subjective symptoms improved after administration of Gamiboik-tang and Korean Medicine treatment Conclusions: Korean Medicine treatment, including Gamiboik-tang administration and acupuncture treatment, is thought to be effective for presbystasis.
