Vertical particle size distribution, total particle concentration, wind velocity, temperature and humidity measurement was performed with a drone. The drone was equipped with a wind sensor, house-made optical particle count(Hy-OPC), condensation particle counter(Hy-CPC), GPS, Temperature, Relative Humidity, Pressure and communication system. Base on the wind velocity and the particle size vertical distribution measurement with drone, the particle mass flux was calculated. The vertical particle distribution showed that the particle number concentration was very strongly correlated with the relative humidity.

Objective: To compare the effects of intermittent mechanical traction with spinal decompression therapy (SDT), using the newly introduced device DRX 3000Ⓡ, in patients suffering from low back pain associated with lumbosacral disc herniation documented on MRI.Method: Thirty-five patients with low back pain with or without lower extremity radiating pain were prospectively enrolled in this study. They were all diagnosed with lumbosacral disc herniation according to physical examinations and MRI. Patients over age 60 years or those with previous spinal surgery, spondylolisthesis, severe osteoporosis, rheumatic diseases, hypertension, and other serious medical problems were excluded. Patients were randomly assigned to intermittent mechanical traction group (15 patients) or SDT group (20 patients) and compared visual analog pain scale (VAS) pre- and post-treatment. Results: There was a significant improvement in VAS in SDT group compared to intermittent mechanical traction group. The mean reduction in VAS for intermittent mechanical traction group equaled 1.93±0.83 (from 6.4±1.28 to 4.5±1.22) while the mean reduction in VAS in SDT group equaled 4.35±2.21 (from 6.9±1.86 to 2.6±1.43) (p=0.0006). Conclusion: Spinal decompression therapy can be used as an effective treatment for discogenic low back pain without serious complications.

Objective To investigate balance control according to the severity of knee osteoarthritis (OA) using clinical tests and Tetra-ataxiometric posturography (Tetrax®). Method A total 80 patients with primary knee OA classified according to American College of Rheumatology criteria, and 40 age-matched controls were enrolled in this study. Of those with OA, 39 patients had mild OA (Kellgren-Lawrence [KL] grade 1, 2) and the other 41 had moderate to severe OA (KL grade 3, 4). The postural control capabilities of the subjects were assessed using the timed up and go test (TUG), Berg balance scale (BBS),and Tetrax®, which utilizes two paired force plates to measure vertical pressure fluctuations over both heels and forefeet. The subjects were checked for their stability index (ST), Fourier index, weight distribution index (WDI),and synchronization index (SI) in eight positions using Tetrax®. Results Patients with moderate to severe OA exhibited signifi cantly higher stability indices in all positions than patients with mild OA. The Fourier index was also higher in patients with moderate to severe OA than in patients with mild OA. However, the weight distribution index and synchronization of both heels and forefeet were not signifi cantly diff erent in the three groups. Conclusion These fi ndings suggest that patients with moderate to severe OA have more defi cits in balance control than those with mild disease. Therefore, evaluation of balance control and education aimed at preventing falls would be useful to patients with knee OA.

One of the most common peripheral joints to be teated in the physicians is the shoulder. The shoulder joint allows the arm to move with respct to the thorax. This motion normally occurs through a complex interaction of the individual motions of the glenohumeral, scapulothoracic, stemoclavicular, acromioclavicular, costosternal, and costovertebral joints as well as the articulation. The casue of shoulder pain are the traumatic arthritis, the immobilization arthritis, perishoulder joints problem, impingement syndrome, adhesive capsulities of shoulder and bursitis, extracapsular ligaments (coracohumeral ligament, coracoclavicular ligament), subdeltoid bursa, and perishoulder tendinitis. The precise physical examination and the diagnosis are the nccessary of treatment of shoulder problem. The methods of treatment of shoulder pain are included in the corticosteroid and local anesthetics injection, the physical therapy, and the exercise of the massage and the stretching.
