Purpose: Sonongraphic examinations such as extended Focused Assessment with Sonography in Trauma (eFAST) are widely used in Emergency Departments. This study is designed to determine student achievement by teaching medical college students through short training. Methods: 38 participants in their 3rd year of medical school were enrolled in this study. An Emergency Medicine physician trained the students to 2 hours of theoretical training followed by 2 hours of hands on training. Results: The average age of students was $28.1{\pm}3.4$, with 21 male students. The average of pre-educational test results were $60.4{\pm}8.9$ and post-educational exam results were $80.1{\pm}14.5$ (p<0.001). The average success rate of eFAST was 87.5%. But success rate of each items were lowest in checking the hepatorenal recess and the splenorenal recess, each success rate, 65.8% and 68.4%, consecutively. The questionnaires filled out after the study showed that the students were highly interested in this education and that they found the education easy to understand. They also answered that eFAST education is necessary in the medical college curriculum. Conclusion: This study shows that eFAST can be effectively taught to students through short training.

Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis manifest as demyelinating diseases of the peripheral and central nervous system. Concurrency of these two disorders is rarely documented in literature. A 4-year-old girl presenting with cough, fever, and an impaired walking ability was admitted to hospital. She had no previous complaints in her medical history. A physical examination revealed lack of muscle strength of the lower extremities and deep tendon reflexes. MRI could not be carried out due to technical problems; therefore, both Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis were considered for the diagnosis. Intravenous immunoglobulin treatment was started as first line therapy. Because this treatment did not relieve the patient's symptoms, spinal MRI was carried out on the fourth day of admission and demyelinating areas were identified. Based on the new findings, the patient was diagnosed with acute transverse myelitis, and high dose intravenous methylprednisolone therapy was started. Electromyography findings were consistent with acute polyneuropathy affecting both motor and sensory fibers. Therefore, the patient was diagnosed with concurrency of Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis. Interestingly, while concurrency of these 2 disorders is rare, this association has been demonstrated in various recent publications. Progress in diagnostic tests (magnetic resonance imaging and electrophysiological examination studies) has enabled clinicians to establish the right diagnosis. The possibility of concurrent Guillain-$Barr{\acute{e}}$ syndrome and acute transverse myelitis should be considered if recovery takes longer than anticipated.

Advances in interactive multimedia and Internet technologies present an array of options that allow the development of very effective training programs. Interactive training is the delivery and management of training using Internet. The trainee actively participates in the training/learning sessions by means of a user-friendly interface that empowers the participant with a sense of control over what they are teaming and the pace at which they are teaming. In this paper, we show process on the development of 3 dimensional e-learing system for Ubiqitous Environment using 3 dimensional supersonic sensor.

Purpose: The purpose of this study was to investigate the effects of upper extremity exercise training on the motor activity, the ADL and the health related quality of life. Method: A non-equivalent pretest-posttest design was used. Study subjects were conveniently selected 40 hemiplegic patients(20 experimental subjects, 20 control subjects) who had been enrolled in two community health centers. After biofeedback training the subjects of experimental group were given constraint-induced movement, involving restraint of unaffected U/E in a sling for about 6 hours over a period of two weeks, while at the same time intensively training the affected U/E. Outcomes were evaluated on the basis of motor activity(amount, quality) of plegic side, ADL(ADL, IADL) and health related QOL(SF-36). Results: 1. After 2 weeks of treatment, the amount of use and the quality of motor activity of affected U/E were significantly higher in subjects who participated in exercise training than in subjects in the control group. 2. There were no significant differences in ADL and IADL between experimental and control groups. 3. After 2 weeks of treatment, the health related QOL was significantly higher in subjects who participated in exercise training than in subjects in the control group. Conclusion: The above results state that the U/E exercise training could be an effective intervention for improving the motor activity and the health related QOL of chronic hemiplegic patients. Long-term studies are needed to determine the lasting effects of constraint-induced movement.

Objective: The purpose of this study was to investigate the effects of different frequency on of knee extensors muscle function during electrical muscle stimulation (EMS). Method: In this research, 40 subjects who have no musculoskeletal disorder, and less than a year workout experience were recruited in order to analyze effects of EMS with different stimulus frequency. Forty subjects were randomly divided into four groups of ten subjects in each group. A EMS training program with different frequencies (without EMS [WE], EMS with frequency 30 Hz [E30], EMS with frequency 60 Hz [E60], EMS with frequency 90 Hz [E90]) was assigned to each group. Throughout eight weeks of training, test subjects were simultaneously carried out knee extension exercises such as squat, leg extension, and leg-press while using EMS with different frequency (20 min, pulse width 250 ㎲, on-off ratio 1:1). Isokinetic knee extension strength, muscle activity of the rectus femoris (RF), the vastus medialis (VM), and the vastus lateralis (VL), and the median frequency of the RF, the VM, and the VL were collected and compared between pre and post training in order to find effects of applying EMS with different frequencies. For each dependent variable, a one-way ANOVA was to determine whether there were significant differences among four different conditions (p<.05). When a significant difference was found, post hoc analyses were performed using the contrast procedure. Results: When compared to WE and E90, E30 causes significant increase in isokinetic knee extension strength. No significant differences were found in EMG values across different EMS conditions. However, the median frequency of the VM in E30 was significantly increased than the corresponding value for WE. Conclusion: The results of this study showed that EMS training with 30 Hz frequency had positive effect on knee extensor. Based of the findings of the present study, EMS training with lower frequency may help the performer to focus on developing strength in knee extensor muscles.

Purpose: Sarcopenia is defined as a decrease in muscle mass, strength, and function with age that affects overall body function. We aimed to investigate the effect of combined training on body composition, balance, and muscle function in sarcopenia elderly. Research design, data, and methodology: Twenty-eight sarcopenia elderly (age 74.9±4.5 years) were randomly assigned to an exercise, EG (n=14), or a control, CG (n=14), group. The EG performed an intervention consisting of combined exercise training (60-75 min) for a total of 12 weeks, three times a week. The CG maintained their usual daily lifestyle during the intervention period. We measured body weight, body mass index (BMI), % body fat, free fat mass, balance ability, peak torque in shoulder, knee, and lumbar joints normalized for bodyweight in one second. Results: The EG showed improved body composition (i.e., BMI, fat-free body mass, fat mass; all p < 0.031, η² > 0.179), balance (i.e., right and left of static and dynamic balance and fast 10 m walk; all p < 0.049, η² > 0.152), and muscular function (i.e., 90°/sec and 180°/sec peak power per kg bodyweight, 90°/sec average power per kg bodyweight, 180°/sec total work, and 180°/sec endurance ratio; all p < 0.045, η² > 0.158). Conclusions: Combined exercise training improves muscle mass and strength, body composition, balance, and muscle function in sarcopenia elderly.
