  • The firing noise produced at artillery test range or military training ground is impulsive burst noise which energy is generated within tens of milliseconds and distributed an isolated burst of sound energy separated to one by one noise. The long range propagation of this noise is affected by a caliber of gun, amount of propellant, distance between source and receiver, ground and meteorological condition. In this paper, main influence parameters have been described based on experimental analysis of measured data. It is considered that this analysis result can be used as useful materials for study of effective firing noise management and development of propagation model.

  • Constraint-induce therapy(CIT) has been documented to improve motor function in the upper extremity of people with hemiparesis. The exercise program uses the training technique 'shaping'. Shaping involves repetitive exercise that are progressed in small steps, where only positive feedback is given to the patients. It involves 14 days of using a restraint on the unaffected arm after stroke for 90% of waking hours. In conjunction with this, ten days of intensive exercise with the affected arm are undertaken for around six hour daily. CIT produces great improvement of motor function with a period of 2 weeks, that the treatment effect remains stable for many months after the end of therapy, and that it transfers into the everyday lives of patients. The purpose of this study is to introduce about the principles of CIT charactieristic, techniques, therapeutic effects-throughout reference books.

  • Exercises are achievement oriented, the process is frequently perceived as hard and difficult Participants drop out from exercise programs in the middle of the training period. Dance movement, which is the deliberate and systematic use of movement, is enjoyable during the movement and provides opportunities for persons to express them-selves. Regular long term dance movement may in-duce a training effect with a decreased drop out rate. Dance movement could be one way to attain wellness, however, there have been few studies to evaluate both physiological and psychological aspects of dance movement. This study focused on evaluating the effects of dance movement training on body weight, resting blood pressure and heart rate, limb circumference and strength, stress response and subjective feelings. This quasi-experimental study was designed as a nonequivalent control group pre test -post test study. Ten healthy fe-male subjects, aged between 19 and 31 years volunteered for an eight week dance movement program. Ten healthy female subjects, between 19 and 21 years of age paticipated as controls. None of the subjects had performed regular physical activity for six months prior to the study. Dance movement was created with reference to Heber's movement guide. The Dance movement program consisted of approximately 30 minutes of dance, three days per week, for eight weeks. During each 30 minute work out, there were approximately 5 minutes of warm-up dancing, 20 minutes of conditioning dance and 5 minutes of cool-down dancing. The intensity for the conditioning phase was at between 60% and 65% of age-adjusted maximum heart rates. Body weight, resting blood pressure and heart rate, circumference of mid upper arm, mid thigh and mid calf, muscle strength of upper and lower limb, physical and psychological response to stress were measured prior to, and following the experimental treatment. Body weight was measured by digital weight scale(Kyung In Corp., Korea). Resting systolic and diastolic blood pressure were measured by sphygmomanometer, Resting heart rate was measured for one minute in a relaxed sitting position using the radial artery. Circumference of mid upper arm, mid thigh and mid calf was determined by tape measure. Muscle strength of the upper extremities was measured by a grip dynamometer (Takei Corp. No.1857, Japan) and that of the extremities was measured by the length of time the leg could be held at 45° Physical and psychological responses to stress were measured using the Symptoms of Stress (SOS)Scale. Paticipants in the dance movement were interviewed by the facilitator following the eight weeks, and their thematic responses about the dance movement were recorded. Following the eight week dance movement train-ing, body weight decreased significantly, circumference of mid thigh and mid calf increased. The length of time leg - raising could be held tended to increase following the dance movement training. Resting systolic and resting heart rate showed a tendency to decrease. Total mean score of stress response tended to de-crease, and mean score of habitual patterns, do-pression, anxiety / fear, anger and cognitive disorganization decreased remarkably following the eight week dance movement. Thematic responses about the dance movement were positive following the training.

  • The purpose of this study was to investigate the effect of exercise training on work capacity, psychologic functions and quality of life in hemodialysis patients. Forteen hemodialysis patients, 3 males, 11 females, age ranged from $23{\sim}58$ years($42.3{\pm}0.4$) were selected and assessed using a modified Bruce protocol on a treadmill. The 3 months supervised exercise training consisted of 60 minites session thrice weekly on the treadmill, bicycle and arm ergometer at $40{\sim}60%$ of maximum $O_2$ consumption. The changes of maximum $O_2$ consumption, psychologic test and quality of life questionnaire in 14 patients before and after 3 months exercise training have been measured. The mean maximum $O_2$ consumption($VO_2$ max) of exercises increased by 23% after training(pre-and postexercise $26.3{\pm}4.6ml$/kg/min vs $29.8{\pm}4.9ml$/kg/min, p=0.013). There was significant reduction in anxiety score(p=0.004) and significant improvement in quality of life score(p=0.031) after training. The result of this study indicated that a structured exercise training for hemodialysis patients provides many benefits. These result suggest the exercise training can improve the work capacity, psychologic functions and quality of life outcomes in hemodialysis patients.

  • Objective To examine the long-term effects of the low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) combined with task-specific training on paretic hand function following subacute stroke. Methods Sixteen participants were randomly selected and grouped into two: the experimental group (real LF-rTMS) and the control group (sham LF-rTMS). All the 16 participants were then taken through a 1-hour task-specific training of the paretic hand. The corticospinal excitability (motor evoke potential [MEP] amplitude) of the non-lesioned hemisphere, and the paretic hand performance (Wolf Motor Function Test total movement time [WMFT-TMT]) were evaluated at baseline, after the LF-rTMS, immediately after task-specific training, 1 and 2 weeks after the training. Results Groups comparisons showed a significant difference in the MEP after LF-rTMS and after the training. Compared to the baseline, the MEP of the experimental group significantly decreased after LF-rTMS and after the training and that effect was maintained for 2 weeks. Group comparisons showed significant difference in WMFT-TMT after the training. Only in the experimental group, the WMFT-TMT of the can lifting item significantly reduced compared to the baseline and the effect was sustained for 2 weeks. Conclusion The results of this study established that the improvement in paretic hand after task-specific training was enhanced by LF-rTMS and it persisted for at least 2 weeks.

  • The aim of this study was to determine the effect of action observational physical training (AOPT) on manual dexterity and corticomotor facilitation in stroke patients. Ten hemiparetic patients participated in this study. Each subject was asked to participate the three conditions; base condition (Base), physical training (PT), AOPT. Participants were asked to observe the action in the video that a therapist moved the blocks during the AOPT conditions. Corticomotor facilitation was determined in three conditions by monitoring changes in the amplitude of motor-evoked potentials (MEPs) elicited in hand muscles by transcranial magnetic stimulation. MEP responses were measured from the first dorsal interosseous after participants attended to three conditions. For the manual dexterity, Box and Block test (BBT) was used. The results of present study were summarized as follows: MEPs amplitude significantly tended to be larger than PT and Base condition. The scores of BBT in the AOPT condition were also significantly larger than other conditions. In conclusion, this finding of present study indicates that physical training for observation of an action is beneficial for enhancing a dexterity of paretic arm in stroke patients.

  • Objective: Bilateral movement training is an effective method for upper extremity rehabilitation of stroke. An approach to induce bilateral movement through functional electrical stimulation is attempted. The purpose of this study is to develop an EMG-triggered functional electrical stimulation device for upper extremity bilateral movement training in stroke patients and test its feasibility. Design: Feasibility and Pilot study design. Methods: We assessed muscle activation and kinematic data of the affected and unaffected upper extremities of a stroke patient during wrist flexion and extension with and without the device. Wireless EMG was used to evaluate muscle activity, and 12 3D infrared cameras were used to evaluate kinematic data. Results: We developed an EMG-triggered functional electrical stimulation device to enable bilateral arm training in stroke patients. A system for controlling functional electrical stimulation with signals received through a 2-channel EMG sensor was developed. The device consists of an EMG sensing unit, a functional electrical stimulation unit, and a control unit. There was asymmetry of movement between the two sides during wrist flexion and extension. With the device, the asymmetry was lowest at 60% of the threshold of the unaffected side. Conclusions: In this study, we developed an EMG-triggered FES device, and the pilot study result showed that the device reduces asymmetry.

  • Purpose : The purpose of this study was to determine the effects of simultaneous application of focal vibration stimulation and task-oriented training on the improvement in upper extremity motor function after stroke. Methods : The study period was from January to April 2019; 23 patients who fulfilled the study eligibility criteria were enrolled. The participants were divided into two groups: the experimental group with vibration stimulation and task-oriented training and the control group with only task-oriented training. Training was conducted in a total of 20 sessions, 5 times a week for 30 minutes a day for 4 weeks. The amount of use of the affected and unaffected side by accelerometers, and Box and Block test (BBT), Action Research Arm Test (ARAT) was measured with a pre-test, a post-test. Wilcoxon Signed Rank Test and Analysis of Covariance were used to compare and analyze the changes within and between the groups. Results : Both the groups showed statistically significant changes in the results of the BBT and the ARAT, as well as the amount of use of the affected and unaffected side. Regarding the use of the affected side, BBT results, and the grasp and gross movement item of the ARAT showed significant changes in the experimental group compared with the control group. Conclusion : We found that simultaneous application of focal vibration stimulation and task-oriented training was more effective than task-oriented training alone. A large-scale comparative study involving a group that is only given vibration stimulation should be conducted for more generalizable results.

  • This report describes a rare, congenital hypertrophy of the left upper extremity that appeared after compressive bandage of right arm at the age of two. He is eighteen years old, and hypertrophy was aggravated for about 2 years since he started weight training exercise. Recently, skin turgor changed and he visited the Dermatology department. Skin biopsy revealed increased thickness of the dermis. On Orthopaedic examination, the left arm showed non­specific neuro-muscular changes other than easy fatigability a.nd increased skin consistency after exercise, compared to the right arm. The differences of circumference were 2.5 to 4cm according to the level of the upper limb. But the relative proportion of hypertrophy of the limb was balanced., On X-ray examination, bony changes were not shown. Through the MRI, we could find edematous changes of subcutaneous fatty tissue. Muscular structures showed unremarkable changes. Through the endurance test of both arms, we could find a decrease in endurance of the left upper arm musculatures. On histologic examination, infrequent focal necrosis and peri fascicular degeneration of the muscle fiber were present.
