The purpose of the study was to evaluate the effects of sling exercise program on muscle activity and cervical spine curvature of person with forward head posture. The subjects, 25 students, were divided into two groups. This experiment was intended to examine the muscle activity and cervical spine curvature while the subjects had performed the exercises to do for 2 times/week and 4 weeks. The factors of FHP were measured cranial vertical angle, cranial rotation angle, muscular activity and cervical spine curvature. Cervical spine curvature measured craniovertical, craniocervical, cervicohorizontal and upper cervical angle. Collected data were statistically analyzed by SPSS 10.0. After experiment for 4 weeks period, results were as following: Both group was significant difference of the results according to the CVA. Exercise group are more effective to increase muscle activity (p<.05), but cervical spine curvature was no significant difference. This result, we could find out there was a significant correlation between sling exercise and muscle activity, CVA and CRA.

The objective of this study was to assess leg muscle activities during whole body vibration (WBV) training with various squat position exercises. Subjects performed four different squat exercises on a vibration platform (VM-10, Sonicworld Co.) Ten healthy women volunteers (age $21{\pm}1.3years$, height $160{\pm}2.1cm$, weight $52{\pm}4.6kg$) were selected. EMG signals four leg muscles were taken and analyzed. The exercises were performed both with 10 seconds WBV and without 10 seconds WBV. Muscle activities during WBV were compared with non-vibration stimulus. In the result, EMG signals caused by WBV were significantly higher (P<0.05) compared with non-vibration stimulus in all leg muscles and squat exercises. The increase in muscle activity caused by Whole body vibration was significantly higher (P<0.05) in LS and OS compared with HU&HS.

This study looked at the effects of teratainment taping and footpad exercise on the improvement of flat foot in a university student. We divided it into flexible flat foot taping group(n=13), flexible flat foot exercise group(n=14), rigid flat foot taping group(n=12), rigid flat foot exercise group(n=13) through a navicular drop test. After one hour's application of teratainment taping and footpad exercise, the height change of navicular, balancing ability and postural stability were evaluated. Change in the height of the navicular was measured before and after intervention, and the balancing ability was measured timed up & go test, and the postural stability ability was evaluated for stability limits in shoulder-width double leg stance, narrow base double leg stance, tandem stance. According to result, there was a statistically significant difference in the left and right foot of the flexible tapping group, right foot of the flexible tapping group, right foot of the rigid tapping group in the change in the height of the navicular in comparison pre- and post- intervention(p<0.5). There were no statistically significant differences in pre- and post- intervention comparisons intragroup and intergroup in balancing ability. There was a statistically significant difference in flexible flat foot exercise group and rigid flat foot taping group in tandem stance in comparison pre- and postintervention in the postural stability(p<0.5). And there was a statistically significant difference in tendem stance of the flexible flat foot exercise group compared to the rigid flat foot exercise group(p<0.5). The results of this study show that teratainment taping and footpad exercise have a significant effect on the improvement of flat foot in adults. Therefore, it is recommended to apply teratainment taping and footpad exercise to improve flat foot.

Explosive blasting performance is composed of charging, tamping and connecting performance, which need lots of power and time. Thus, operator's inconvenience and muscle load are increased by their pose. Then it's unavoidable for one to make a human error. As a result, blasting accidents and disasters of explosives may happen. So we need to have systematic study. According to their pose's changing we have OWAS, RULA, REBA, OSHA, ISI, NLE, TVAV, BLUE-X. In this article, OWAS, RULA, REBA have been evaluated. As a result of this research, it is shown that work-related musciloskeletal disorders are related to the second accident's happening.

본 논문에서는 비디오 영상열 내에 컴퓨터가 생성한 가상의 3D 영상을 이음새 없이 추가하기 위한 문제에 초점을 맞추고 있다. 2단계의 견고한 통계적인 메소드는 추적된 커브들의 모델-영상 대응점으로부터 보다 정확한 자세를 평가하기 위하여 자세 계산을 위해 사용되었다. 또한, 관점의 정확성 향상을 위하여 두 개의 연속하는 영상들간에 매치될 수 있는 핵심점을 카메라 움직임에 대한 상관관계 함수로 사용하여 매칭 에러와 reprojection 에러를 포함한 비용함수를 최소화함에 의해 관점을 향상시킨다. 비디오 영상내 객체 영상과 가상의 3D 영상간에 발생하는 폐색 공간문제를 해결하기 위하여 반 자동 알고리즘을 제안하였다.

The purpose of this study was to determine whether changes of position might effect the convergence pulmonary function of the 20s men of mild intellectual disabilities with obesity. Ten subjects of mild intellectual disabilities with obesity(fat group) and ten contrary subjects without obesity(control group) were participated in the experiment. Subjects were assessed for their pulmonary function by using Fit mate according to the position changes(supine position, 45 lean sitting position, 90 sitting position). One-way repeated ANOVA analyzed each region data of pulmonary function of both the fat group and the control group according to their position changes. The result of the experiment showed that the 20s men of mild intellectual disabilities with obesity have lower pulmonary function than the contrary subjects in the each given posture. In comparison with three experimental positions, supine position was the lowest in the pulmonary function. This study showed the 20s men of mild intellectual disabilities with obesity have lower function of pulmonary volume than the control group, and thus, it suggests that the pulmonary functional data of 20s men of mild intellectual disabilities with obesity in this experiment can be used as a basic respiratory one for the various exercise programs in the area of the physical activities.

In Order to Diagnose Maxillary Bone and Maxillary Sinus in the X-Ray Paranasal Sinus Projection test, this Study used Skull Rando Phantom to Change the Posture and X-ray tube Angle to 5° of the Head or 5° of ROC Who worked for more than 10 years. The Significance of the Evaluated score was Verified through SPSS Ver. 3.0, and the Cronbach value was Significantly higher at 0.712. In addition, as a Result of Calculating SNR by Setting the ROI(Receiver Operation Characteristic) of the Maxillary bone and Maxillary sinus images, it was the Highest at 6,449 in the Examination by tilting 5° toward the Head or Leg of the X-ray tube. In the study, it is believed that among the X-Ray simple Paranasal Sinus projection tests, a sharp Image can be Obtained during the Examination by Tilting the X-ray tube 5° toward the Head or Leg.
