Purpose : The purpose of this study was to compare the plaque removal effects of vacuum oral cleaner developed for the patients with limited mobility with those of manual toothbrushes and high pressure injection oral cleaner (dental water jet). Meterials and methods : Thirty human subjects were measured with Patient Hygiene Performance index (PHP index) and O'Leary index before and after the use of toothbrush, high pressure injection oral cleaner and vacuum oral cleaner. These three different oral hygiene methods were conducted with seven-day intermittence. Then the statistical analysis was carried out to define plaque removal rate of three different oral hygiene methods (${\alpha}=.05$). Results : According to the efficacy analysis of plaque removal before and after the oral cleaning using each of three methods, significant reduction in plaque after the treatment compared to the previous state when using toothbrush, high pressure injection oral cleaner, and vacuum oral cleaner was observed (P < 0.001). PHP index of tooth brushing was higher than that of the high pressure injection oral cleaner, while PHP index of vacuum oral cleaner did not show significant difference from either of the other two methods. There was no significance difference in O'Leary index among the three methods. Conclusion : Effect of plaque removal using the vacuum oral cleaner is comparable to that of manual tooth brush or high pressure injection oral cleaner, so it will be helpful for self-oral hygiene care of the patients with limited mobility.

The purpose of the study was to determine the effects of balance training with 'TETRAX' system, a balance training and assessment tool, on balance and mobility in acute hemiplegic patients. Nineteen matched subjects were assigned randomly into either an experimental group or a control group. An experimental group with 10 subjects received balance training with 'TETRAX' exercise program and conventional physical therapy interventions 5 times per week during 4 weeks. A control group with 9 subjects received conventional physical therapy interventions 5 times per week during 4 weeks. Outcome measures were taken before and after 4 weeks of interventions using the Stroke Rehabilitation Assessment of Movement (STREAM), the Berg Balance Scale (BBS), gait speed, and the fall down index. Results indicated that both exercise groups improved significantly in STREAM, BBS, and gait speed (p<.05). The experimental group had a little improvement than the control group. Both exercise groups did not show statistical significance in fall down index (p<.05). Following 4 weeks of intervention, except gait speed there was no statistically significant difference between two groups. However, these findings suggest that conventional physical therapy interventions with visual feedback training could be effective on improving balance and mobility than conventional physical therapy alone in acute hemiplegic patients.

PURPOSE: Despite the widespread occurrence in the general population, few studies have directly evaluated the effects of shingles on non-specific neck pain (NSNP). This study investigated whether sensory training or therapeutic stretching exercises are more effective in increasing neck mobility and reducing neck pain in chronic NSNP patients. METHODS: Eighty-one subjects aged between 20 and 32 years with chronic neck pain (> six months), were allocated randomly to three groups: sensorimotor training group (STG), therapeutic stretching group (TSG), and home exercise group (HEG). All participants received a half-hour training session, three times weekly for six weeks. The outcomes were evaluated using the neck disability index for measuring neck pain, and a universal goniometer to measure the cervical passive range of motion before and after the six-week intervention. RESULTS: The post-test neck disability index scores in the STG (t = 4.86) and TSG (t = 3.24) were decreased significantly (p < .05). The passive range of motion changes in all cervical movements in the STG was increased significantly (p < .05) after intervention compared to those in the other two groups. CONCLUSION: Sensorimotor training using chin tuck exercises may improve neck pain and mobility in subjects with chronic NSNP.

The purpose of this study was to investigate the variables related to the propensity of the residential mobility among the Rental Apartment Residents in Gwangju. A total of 303 housewives living in the rental apartment in Gwangju completed a structured questionnaire during Aug. 19-30, 2000. The major findings were as follows. 1. The Rental Apartment Residents were more likely to move rather that to stay. 2. The level of the general housing satisfaction was not high(2.92). 3. The significant variables that influenced on the propensity of the residential mobility were size of the house, satisfaction of the management services, duration of the residence, age of the housewives and general housing satisfaction. In future research, the variables related the housing satisfaction have to be sought respectively and the index of the housing satisfaction and the propensity of the residential mobility have to be made.

In this paper, mobility performance indices are proposed which may be used to estimate characteristics of output velocity space in six-degree-of-freedom parallel mechanism. In order for manipulability and condition number to not suffer from lack of the physical meaning due to dimensional inhomogeneity, output space is partitioned into translational velocity space and rotational velocity space, respectively. In each space, mobility ellipsoids corresponding to unit input space are defined and two types of mobility performance in translational velocity spaces indices are derived. Two types of mobility performance in rotational velocity spaces indices are derived.

Objective: The aim of this study was to evaluate the effects on pain and function of patients with rotator cuff tendinopathy when applying trigger point of infraspinatus and teres minor to myofascial trigger point release (MFR) plus mobility exercise and MFR. Design: A randomized controlled trial. Methods: The total participants were 30patients and were separated to MFR plus mobility exercise group(n=15) and MFR group (n=15) according to the randomized treatment method. The MFR was performed at two infraspinatus tampon points and one teres minor tampon point for twice a week for 4 weeks and the treatment time was 6 minutes 20 seconds in each position. The MFR group also carried out the myofascial trigger point release in the same way as the MFR plus mobility exercise group. Results: The MFR plus mobility exercise group significantly reduced objective and subjective pain (p<0.05). The range of motion of the shoulder joint flexion and external rotation, Quick-Disability of the Arm, shoulder and Hand, and Shoulder Pain and Disability Index were significantly improved in the group to which MFR plus mobility exercise was applied (p<0.05). Conclusions: These results confirmed that MRF plus mobility exercise is more effective in relieving shoulder pain and improving function in rotator cuff tendinopathy.

Based on the work of Anand et al. (2013) we measure inclusive income growth, which combines growth in gross domestic product (GDP) per capita and growth in the equity of the income distribution. Extending the work of Causa et al. (2014), we estimate a dynamic simultaneous structural equations model of GDP per capita and inclusive income on panel data for 63 countries over the 1990-2013 period. We estimate both equations in error correction form by difference GMM (generalized method of moments). Among the explanatory variables of the level and the distribution of GDP per capita we include R&D (research and development) expenditure per capita. In OECD countries we obtain a large positive effect of R&D on GDP. R&D is found to have a positive effect on the social mobility index but its impact on the income equity index at first decreases, then switches around to become slightly positive in the long run. In non- OECD countries, R&D is found to decrease inclusive income, mostly through a negative growth effect but also because of a slightly increasing income inequity effect.

Due to the increasing use of smart phones, using Wifi, Wibro of mobile devices spread. Accordingly, Need of using peer-to-peer file sharing between mobile devices is growing. However, common Peer-to-Peer(P2P) system is too complex and is not suitable to be applied to mobile devices. Thus, the need of research has shown to improve way in a mobile environment that has a constraints as mobility and the scope of communication. Among them, there is a Chord as contents look up algorithm. Chord is the issue. Chord as the DHT-based P2P protocol shares files, index-key and distributed key across the network. However, exist Chord doesn't consider the mobility. So, It has a lot of problems in the mobile environment. Thus, in this paper, I will try to explore an appropriate way of Chord in a mobile environment.

Teeth mobility is an important part of a periodontal examination, because it represents a function of the persisting height of the alveolar bone and the width of the periodontal ligament. The purpose of this study was to evaluate clinical difference in teeth mobility after treatment with the modified Widman flap and the undisplaced flap in humans. Twenty males with moderate periodontal disease were selected. The severity of periodontal disease was evaluated with sulcular bleeding index, pocket depth and attachment level and tooth mobility was measured with Periotest(Siemens Co., Germany) at the initial examination, 1, 2, 4, 6, 8 and 12 weeks following the modified Widman flap and the undisplaced flap operation using the split-mouth technique. The relation of mobility to clinical parameters was statistically analyzed by multiple regression and the change of teeth mobility according to healing process by independent t-test using SPSS program. The results were as follows: 1. There was a strong relationship between the Periotest value(PTV) and attachment level. 2. The change of teeth mobility in both flap procedures was increased significantly at 1 week post-op. and was decreased to preoperative level at 4 weeks post-op, in modified Widman flap and at 6 weeks post-op. in undisplaced flap. 3. The change of teeth mobility in premolar teeth group in undisplaced flap compared to modified Widman flap was generally increased but these changes were not statistically significant. The changes of teeth mobility in molar teeth group in undisplaced flap was increased significantly at 2 weeks post-op.. 4. The change of teeth mobility following undisplaced flap was increased significantly compared to that of modified Widman flap at 2 weeks post-op.

The dynamic stability of a robot vehicle can be enhanced by the Force-Angle Stability Margin concept that considers a variety of dynamic effects. To evaluate the robot vehicle stability, a SPI(stability performance index), which is a function of the suspension arm angles, was used. If the SPI has a minimum value, the robot vehicle has maximum stability. The FASM and SPI concepts were incorporated in the mobility simulation by using ADAMS and MATLAB/Simulink. The simulation results using these concepts showed significant improvements of the vehicle stability on rough terrains.
