Purpose: The purpose of this study is to examine the effects of postural control training using a horseback riding simulation on the spinal alignment of children with cerebral palsy. Methods: This study was conducted with 30 children with cerebral palsy at levels I~IV in the Gross Motor Function Classification System (GMFCS), and they were randomly divided into a control group and a hippotherapy group. Both the control group and the experimental group received NDT for 30 minutes per session, four times per week for ten weeks, while the experimental group also received hippotherapy 15 minutes per session, four times per week for ten weeks, after the neurodevelopmental treatment (NDT). The horseback riding simulators (JOBA, EU7805, Panasonic) used in this study simulated actual horse movements. Trunk imbalance, pelvic torsion, and pelvic tilt were measured in each group before the exercise and five weeks and ten weeks after the beginning of the exercise using a spinal structure analysis system (ABW Mapper). Results: The Intra-group effects on trunk imbalance, pelvic torsion, and pelvic tilt according to the exercise periods after the hippotherapy were tested, and the results showed significant interaction effects between the groups and the periods (p<0.05). Conclusion: The horseback riding simulation exercise was shown to be effective for the spinal alignment of children with cerebral palsy. Therefore, additional studies should be conducted with more children with CP divided by type.

The study aimed at development of a riding-type mulberry harvester for mechanical harvest. A riding-type mulberry harvester has been developed to harvest on sloped land with a higher efficiency. It has been implemented over a period of 2 years from 1996 to 1997. The result is as follows. It moves on carterpillar with a level adjusting system. It reduced only from 14.6 hrs to 0.9hrs/10a for cutting in a range of 25 to 80 cm high and possibly used for both spring and autumn. It reduced only the labor requirements of mulberry harvesting by 94 percent, as compared to that of the manual harvest. All related processes, cutting, binding and loading are simultaneously done by this harvester and totally it can reduce 96 percent of the labor requirements, as compared to 20.4 hrs/10a of the manual harvest. The machine compared to improved mulberry harvest efficiency with 11.11a per hour by about 23 times as compared to 0.49a per hour manpower. Cost analysis indicated that the riding-type mulberry harvester saved overall cost by 66 percent from 980,000 won per ha manpower to 330,000 won per ha.

This study was performed on 26 disabled adolescent participants (16 male, 10 female) with the objective of testing changes in equilibrium after engagement in horseback riding. Participants of total 26 persons were divided into three groups as follows: 6 children with Cerebral Palsy (CP), 14 children with Intellectual Disability (ID) and 6 children with Autism (AT). Participants engaged in therapeutic horseback riding (TR) two times per week for 30 minutes per session. The 26 participants demonstrated a considerable increase in equilibrium ability, with an average increase in equilibrium time of $44.22{\pm}50.70$ sec after TR. Equilibrium also increased according to disability group: CP (P < 0.05), ID (P < 0.001), and AT (P < 0.05). TR should be considered as a possible method for improving functionality in the physically disabled. This data may also be usefully applied to the development of a horseback riding program for the improvement of equilibrium in the disabled.

Purpose: The purpose of this study is to examine the effects of using a horseback riding simulation on static balance in children with cerebral palsy. Methods: This study was conducted with 30 children with cerebral palsy at levels I~IV in the Gross Motor Function Classification System (GMFCS), who were randomly divided into a control group and a hippotherapy group. Both the control group and the experimental group received NDT for 30 minutes per session, four times per week, for ten weeks, while the experimental group also received hippotherapy, 15 minutes per session, four times per week, for ten weeks, after the neurodevelopmental treatment (NDT). The horseback riding simulators JOBA (JEU7805, Panasonic, 일본) used in this study simulated actual horse movements; static balance was measured in each group before the exercise and five weeks and ten weeks after the beginning of the exercise using a pedoscan system (Diers Pedo, Germany). Results: The intergroup effects on static balance were tested, and the results showed no significant differences (p<0.05). Conclusion: The horseback riding simulation exercise was shown to be effective for the static balance of children with cerebral palsy. Therefore, additional studies should be conducted with more children with CP divided according to type.

Purpose : The purpose of this study has been performed to find the effect of horseback riding simulation training on the thickness of abdominal muscles and functional balance in children with down syndrome. Methods : This study included 10 children with down syndrome aged between 7 and 13 years. Both groups received regular neurodevelopmental treatment, also experimental group was performed for additional 15 minutes horseback riding simulation training for twice a week during 8 weeks. We measured the thickness of abdominal muscles by using ultrasonography and measured of functional balance by using Pediatric Berg's Balance for the subjects agreed to the before, after 4 weeks and 8 weeks the training. Results : There were no significant difference in the thickness of the internal oblique and external oblique muscles. There were significant difference in transverse abdominis thickness and functional balance that experimental group had increased average than control group after 4 weeks and 8 weeks training Conclusion : Horseback riding simulation training has a positive effect on the improvement of transverse abdominis muscle thickness and functional balance in children with down syndrome.

P2P 파일 공유 시스템에서 서비스를 이용하는 모든 사용자들은 동등한 권한으로 자유롭게 여러 사용자들의 공유 파일을 이용할 수 있기 때문에, 자신의 파일에 대한 공유 없이 다른 사용자들의 공유 파일을 다운로드만 하는 "free riding" 문제가 빈번하게 발생하고 있다. 본 논문에서는 이러한 문제점을 해결하기 위해 기존 P2P 서비스에 "평판" 정보를 적용하여 피어의 서비스 기여도를 고려함으로써 "free riding" 문제를 해결할 수 있는 새로운 P2P 파일 공유 서비스를 제안한다.

The Purpose of this paper is to characteristics and analysis of ride comfort by using HRV. Although the riding comfort of trains has been managed by setting allowable accelerations of 3-axis motion in cabins, it is impossible for this approach to express the psychophysical relationship between various vibrational factors and riding comfort. in order to propose a function to evaluate the riding comfort of train on conventional railroad, an experiment was performed with the Korea Tilting Tran eXpress(TTX). As a result, by referring to some international standards on the method of evaluating ride comfort, a modified method was proposed to evaluate the lateral vibration in addition to the roll motion on carve transitions.

Although the riding comfort of tilting trains has been managed by setting allowable limits of roll motion in Korea, it is impossible for this approach to express the psychophysical relationship between various vibrational factors and riding comfort. in order to propose a function to evaluate the riding comfort of tilting train on transition curves, an experiment was performed with the Korea Tilting Tran eXpress(TTX). As a result, by referring to some international standards on the method of evaluating ride comfort, a modified method was proposed to evaluate the lateral vibration in addition to the roll motion on carve transitions.

We report a case of atlantoaxial subluxation with bilateral high-riding vertebral artery with narrow isthmus. Because of the potential risk of bilateral vertebral artery injury, we performed atlantoaxial fixation using rod and screw instead of transarticular screw fixation. Although postoperative computed tomography reconstruction demonstrated slight breach of bilateral vertebral artery groove, postoperative angiography showed no evidence of vertebral artery injury. Though technically demanding, atlantoaxial fixation using rod and screw can be a one of the treatment options for atlantoaxial instability with bilateral high riding vertebral artery.
