Fractures located at the metaphyseal/diaphyseal junction at the base of the fifth metatarsal were first described by Sir Robert Jones in 1902. However, ever since, there has been disagreement and debate regarding the diagnosis, classification, pathomechanics, the incidences, and potential causes of delayed unions and nonunions, and the optimal method of treatment. It appears to be widely agreed that proximal fractures of the metaphyseal/diaphyseal region of the fifth metatarsal are prone to delayed union or even nonunion. Several classifications of proximal fifth metatarsal stress fractures have been devised. Torg et al. classified fractures involving the proximal part of the diaphysis of the fifth metatarsal into three types. The Torg classification is a good grading system that can be used to determine the type of surgery needed as well as for the prediction of prognosis. The ''plantar gap'' might add to the decision-making process for surgery and improve the prediction of patient prognosis. In addition, the new classification using 'plantar gap' might be used for classification of fifth metatarsal stress fracture. Fifth metatarsal stress fractures can be treated conservatively or surgically, and excellent results have been reported for surgery with rapid recovery in athletes. Intramedullary screw fixation has become a popular form of fixation for fifth metatarsal stress fractures. Bone grafting presents the problems of a longer recovery time and additional skin incision for harvesting. The modified tension band wiring is an useful and simple option for surgical treatment of challenging fifth metatarsal stress fractures.

The purpose of this study was designed to find out the effectiveness of vertebral segment instability, muscle fatigue response on lumbar spine after apply lumbosacral stabilization exercise program to 4 patients with chronic low back pain and for 12 weeks. In this study, the lumbar spine motion with blind by MedX test machine and the difference of instability to lumbar vertebra segments in flexion, extension test of standing position and spinal load test(Matthiass Test) by Spinal Mouse. The stabilization exercise program was applied 2 times a week for 12 weeks in hospital and 2 times a day for 20 minutes at home. The results of the present study were as follows: 1. Instability test of lumbar vertebra segment is 2 type differential angle test between vertebrae segment and loading test of spine(matthiass) by Spinal Mouse. It appeared to improve stability of segments in sagittal plane after applying program. So lumbar spine curve increased lordosis toward anterior and was improved of the lumbar spine flexibility in flexion and extension. Specially, in matthiass test, (-) value was increased between lumbar vertebra segment when was the load on spine. And so applying stability improved after program. 2. Fatigue response test(FRT) results, in male, was raised muscle fatigue rate during increase weight, on the other hand female appeared lower than male. As a results, lumbosacral stabilization exercise was aided to improvement of lumbar spine vertebra segments stabilization. Spine instability patients will have a risk when in lifting a load or working with slight flexion posture during the daily of living life and it is probably to increase recurrence rate. Thus, not only lumbar extension muscle strength but also stability of vertebra segments in lumbar spine may be very important.

풍력 터빈의 용량이 대형화될수록, 난류성분에 의한 풍력 터빈 구조물의 하중을 최소화시키는 하중완화 제어가 점차 중요해진다. 한번 설치되면 20 년 이상 작동되어야 하는 풍력 터빈 구조물은 끊임없이 바람에 의한 하중에 노출되는데, 이것이 적절하게 제어되지 않으면 풍력 터빈의 회전 반복운동에 의하여 피로파괴에 이르게 될 가능성이 커진다. 본 논문은 NREL 5MW 풍력 터빈을 대상으로 타워의 하중을 저감시키는 제어시스템을 설계하고, 이의 성능을 평가하는 내용을 담고 있다. 타워의 하중 완화제어시스템을 설계하려면 5MW 풍력 터빈의 동적 특성이 먼저 파악이 되어야 하며, 파워 커브를 추종하는 기본 제어시스템의 설계가 선행되어야 한다.

PURPOSE: This study tries attempted to provide basic clinical data to reduce pain and improve function by comparing the muscle fatigue of the superficial neck muscles and neck disability index (NDI) by performing McKenzie exercise or passive stretching exercise for chronic neck pain patients. METHODS: Sixteen chronic neck pain patients were selected and divided into the McKenzie group (n=8) and passive stretching group (n=8). The intervention program was performed three times a week for four weeks. The time for one exercise was 30 minutes. Before the intervention, the muscle fatigue the superficial neck muscles and NDI were measured. They were measured again after four weeks using the same method. RESULTS: The median frequency of the superficial neck muscles increased significantly in the McKenzie group and passive stretching group (p<.05). The NDI of both the McKenzie group and the passive stretching group decreased significantly. A comparison of the groups, revealed a significant difference in only the median frequency values of the upper trapezius muscle and splenius capitis muscle (p<.05). The NDI values of both groups were similar. CONCLUSION: Both McKenzie exercise and passive stretching exercises showed a significant difference in the degree of fatigue and NDI. McKenzie exercise delayed the replace of the fast twitch fibers which helped improve the muscle fatigue of the upper trapezius muscle and splenius capitis muscle. On the other hand, additional studies applying more variables for the muscle function to improve the symptom of chronic neck pain patients will be needed.

파랑에 의해 발생하는 해양구조물의 진동을 억제하기 위해 동조질량감쇠기(Tuned Mass Damper, TMD)를 적용하여 그 효과를 분석하였다. 해양구조물의 운동방정식에 포함된 파랑-구조물 상호작용에 의한 비선형성을 선형화한 경우의 오차와 TMD설계시 선형방정식을 사용한 경우 발생할 수 있는 현상을 분석하였다. TMD설치 전후의 제진효과 분석에서는 주기를 달리한 규칙파에 의한 성능과, 유의파가 서로다른 불규칙파에 의한 성능을 동시에 분석하였다. 규칙파에 의한 해석결과 입사파의 주기가 구조물의 첫 번째 고유주기와 근접한 경우 제진효과가 뛰어났으며 주기가 더 짧거나 더 긴 경우는 제진효과가 감소하였다. 불규칙파에 의한 해석결과는 유의파가 상대적으로 작아 구조물의 고유주기 성분이 많이 포함된 파랑에 대한 제진효과가 뛰어나고, 유의파가 커서 구조물의 고유주기 보다 큰 성분이 많이 포함된 파랑에서는 제진효과를 발견할 수 없었다. 따라서, 해양구조물에 TMD를 적용할 때는 파고가 작은 상시 내습 파랑에 대한 제진효과를 볼 수 있으며 이는 상시 진동제어를 통한 피로수명 확보에 큰 도움이 될 것으로 예상된다.

Background: The purpose of this study was designed to find out the effectiveness of reposition sense, muscle fatigue response on lumbar spine after apply lumbosacral stabilization exercise program to 4 patients with chronic low back pain and for 12 weeks. Method: In this study the reposition sense was measured in 3 angle(60, 30, 12) of the lumbar spine motion with blind by MedX test machine and the difference of instability to lumbar vertebra segments in flexion, extension test of standing position and spinal load test Mattress Test by Spinal Mouse. The stabilization exercise program was applied 2 times a week for 12 weeks in hospital and 2 times a day for 20 minutes at home. Result: The results of the present study were that the repositioning sense was appeared the most error in 12 angles of lumbar flexion and Men was appeared to decrease an error more than female in average value of 4 angles after 12 weeks. And average error of male was decrease more than female. Thus the effects of lumbosacral stabilization exercise was improved repositioning sense of prorioceptor. Fatigue response test(FRT) results, in male, was raised muscle fatigue rate during increase weight, on the other hand female appeared lower than male. Conclusion: As a results, lumbosacral stabilization exercise was aided to improvement of lumbar spine repositioning sense and vertebra segments stabilization. It was showed the rate of decrease in typically 12 degree angle point of each 3 angle(60, 36, 12). Especially, that spine instability patients will have a risk when in lifting a load or working with slight flexion posture around 12 degree during the daily of living life and it is probably to increase recurrence rate. Thus, not only lumbar extension muscle strength but also stability of vertebra segments in lumbar spine may be very important.
