Parkinson's disease is a slowly progressive degenerative disorder of the central nervous system. It is characterized by tremor when muscles are at rest, increased muscle tone, slowness of voluntary movements, and difficulty maintaining balance. In oriental medicine, these symptoms are diagnosed as yin(陰)-deficiency of liver and kidney, deficiency of qi(氣) and blood, retention of phlegm(痰), qi-stagnation and blood stasis. In this case, we diagnosed patients as deficiency of qi(氣) and blood type according to symptoms and treated by herbs that strengthen yang and benefiting yin for two weeks, while maintaining existing parkinson's western medication. After treatment, clinical symptoms were improved, while UPDRS (Unified Parkinson's Disease Rating Scale) score was decreased. These cases suggest that oriental medicine therapy maybe effective in the treatment of Parkinson's disease.

Studies of attentional focus effects, have shown that the performer's attentional focus plays an important role in the performance and learning of motor tasks. We examined the influence of attentional focus on the performance of dual tasks (a postural task and a suprapostural task) and used electromyography (EMG) to examine whether the differences between external and internal focus were also manifest at the neuromuscular level. The subjects (n=40) stood on a balance board (postural task) and held a bar horizontally (suprapostural task). All of the subjects performed under different attentional focus conditions: external (balancer on balance board) or internal (feet) focus on the postural task, and external (balancer on bar) or internal (hand) focus on the suprapostural task. The mean displacement velocity of the bar and the percent reference voluntary contraction (%RVC) of the biceps brachii were reduced when the subjects adopted an external focus on the suprapostural task (p<.05). In addition, the mean displacement velocity of the balance board and %RVC of the tibialis anterior were reduced when the subjects adopted an external focus on the postural task (p<.05). When the subjects adopted an external focus on the suprapostural task, the mean displacement velocity of the balance board and %RVC of the tibialis anterior were also reduced (p<.05). When the subjects' attentional focus was on the postural task, there were no differences in the mean displacement and %RVC of the biceps brachii between attentional focuses. The performance of each task was enhanced when subjects focused on the respective task. The suprapostural task goals had a stronger influence on postural control than vice versa. These results reflect the propensity of the motor system to optimize control processes based on the environmental outcome, or movement effect, that the performer wants to achieve.

Purpose: The aim of this study was to identify the effects of the lower trunk stabilization exercise using neurodevelopmental technique (NDT) on muscle activity in lumbar region and balance in the patients with hemiplegia. Methods: Fifteen participants were allocated in two groups: NDT group (n=8) or control group (n=7). NDT group performed NDT exercise program, while control group conducted walking exercise. Both interventions were given for 30 minutes a day, 3 times a week, for 5 weeks. To measure the muscle activity in rectus abdominis (RA), external oblique (EO) and internal oblique (IO), electromyography (EMG) was used. And, Timed-Up and Go (TUG) test and Berg-Balance Scale (BBS) were performed to assess balance before and after intervention. Results: NDT group showed a significant improvement of muscle activity in RA and EO, while control group did not show significant changes in three muscles. Also, there was a significant difference in muscle activity of RA and EO between two groups. In BBS and TUG test, participants in two groups showed significant improvements after intervention. Especially, significant difference was observed in TUG test between two groups (p<.05). Conclusion: This study demonstrated that NDT exercise is an effective intervention to improve the muscle activity in trunk region and to increase balance in patients with stroke. Thus, we suggested that NDT exercise program would be a treatment intervention in stroke rehabilitation.

This study aimed to provide help to seeking a preventive method of intervention in firefighter's job satisfaction by investigating the role of perceived organizational support in the relationship between firefighter's work-life balance and job satisfaction. For the foregoing, this study investigated by conducting purposeful sampling targeting 115 firefighters in Gyeonggi-do. Study results show that firefighter's work-life balance has a significant influence on job satisfaction, perceived organizational support turned out to have a significant moderating effect between work-life balance and job satisfaction. As a Wellness Convergence, based on the results, this study showed a possibility for application of perceived organizational support as a firefighter's internal coping resource, suggesting positive introduction of preventive and effective 'policy for work-life balance' and support to derive job satisfaction.

PURPOSE: This study is examined the effects of vestibular stimulation through eye movement on balance and muscle activity. METHODS: In 42 healthy adults, no eye exercise was applied to both feet and one foot. The speed of smooth pursuit eye movement (.2 Hz, .3 Hz, and .5 Hz) and saccadic eye movement (.5 Hz and 1.1 Hz) were randomized. The measurements were taken three times for 30 seconds while standing on two feet and measured three times for 10 seconds while standing on one foot. The muscle activity measurement equipment was used to measure the electromyogram signals of the tibialis anterior, peroneus longus, gastrocnemius medialis, vastus medialis, vastus lateralis, biceps femoris, abdominal internal oblique, and erector spinae muscle. RESULTS: As a result of this study, when applying smooth pursuit eye movement on one leg, the pressure center movement increased, the muscle activity of the lower extremity increased, in the saccadic eye movement, and the center of pressure decreased. CONCLUSION: Accordingly, the smooth pursuit of eye movement, the intervention of this study, affects balance. Through this, the balance can be improved by applying eye movement to the target who needs to improve the balance ability.

Objectives : It is considered not easy to diagnose the condition of acupoints or meridians. Oriental Medical instruments have rarely complied with Oriental Medical diagnostic/therapeutic theories. The aim of this study was to develop a system which measures meridian electric potential(MEP) in proportion to bio-electric charge for the purpose of Oriental Medical diagnosis. Method : To evaluate a meridian energy measurement system(MEMS), we carried out a performance test. For significance test, we conducted a clinical trial which measured the MEP of ST36(Chok-samni) on Stomach Meridian(ST). Results & Conclusions : We could evaluate the balance or the imbalance of the MEPs on the left/right ST36. Also, through the comparison of MEPs before and after meals, we could identify the correlation between the MEP and the condition of internal organs. Namely, MEP reflects the condition of acupoints/meridians and internal organs, therefore, we propose this new method for measuring and analyzing the condition of meridians and acupoints for Oriental Medical diagnosis.

The influences of injection conditions and recess configuration of liquid-liquid swirl coaxial injector on spray characteristics were investigated. The characteristics of the coaxial spray in internal mixing injection region were mai y controlled by the merging phenomenon and momentum balance between two liquid sheets, but those in internal mixing injection region were influenced by the impingement phenomenon as well as momentum balance between two liquid sheets.

Internal waves and internal tides occur frequently along the eastern coast of Korea. During the spring-tide period in April 2003, the East Korean Warm Current (EKWC) flowed near the Korean East Coast Farming Forecast System (KECFFS; a moored oceanographic measurement system), creating a strong thermocline at the intermediate layer. Weakened stratification and well-mixed water appeared frequently around the KECFFS, with duration of approximately 1 day. The results suggest the following scenario. Baroclinic motion related to the internal tide generated high frequency internal waves around the thermocline. The breaking of those waves then created turbulence around the thermocline. After well-mixed water appeared, a current component with perpendicular direction to the EKWC appeared within the inertial period. The change in stratification around the KECFFS locally broke the geostrophic balance as a transient state. This local vertical mixing formed an ageostrophic current within the inertial period.
