A practical method to design the input shaping which generates control command is proposed in this paper, We suggest an experimental technique considering human operator's target tracking error to improve aiming accuracy which significantly affects hit probability. It is known that stabilization performance is one of the most important factors for ground combat vehicle system. In particular, stabilization error of the manual target tracking system mounted on moving vehicle directly affects hit probability. To reduce this error, we applied input command shaping method using preprocessing filtering and functional curve fitting. First of all, we construct the human operator model to consider effects of human operator on our system. Input shaping curve is divided into several regions to get rid of the above problems and to improve the system performance. At example design part, we chose three steps of functional command curve and determine the parameters of the function by the proposed design method. In order to verify the proposed design method, we carried out the experiments with real plant of a fighting vehicle.

Background: The purpose of our experimental study, we want to know a correlation study using the sonogram between the muscle strength and the diameter of Biceps brachii muscle by gender. So we set to hypothesis that Biceps brachii contracted maximally would be a diameter of the muscles increased according to the muscle strength will be increased. Methods: In this study, we measured the muscle strength of biceps brachii on contracting its maximum using the Biodex and the diameter of the muscles using Myo-Lab (25Gold). We experimented 30 subjects of twenty-aged men and women. The subjects is comprised of a persons who has not external injuries and pain of elbow joint, no mobility limitation of ROM, no experiences of surgery in past history. Result: We found that the men have a highly correlation between maximum strength and the diameter of the muscles more than women (p<.05). Conclusion: The results of our experimental study between the muscle diameter and the muscle strength to biceps brachii on relaxation and contraction is a statistically significant relation (r=.394), especially in rather men then women (p<.05). So this results would be based data for further clinical muscle efficiency application in physical therapy field.

Background: This study aimed to the effects of hip mobilization on pain, trunk flexibility, function for chronic low back pain patients. Methods: Patients were randomly assigned to control group (n=15) and experimental group (n=15). Both groups received conventional physical therapy, three times a week for four weeks. Experimental group was performed additional hip mobilization, three times a week for four weeks. All measurement of each subject were measured at pre-intervention and post-intervention (after 4 weeks). Results: Assessed items included the visual analog scale score (VAS), Korean version of the Oswestry disability Index (KODI) a significant reduction was observed post intervention compared to pre-intervention values in both group (p<.01). Trunk flexibility was significant increased post intervention compared to pre-intervention values in both group (p<.01). There were significant difference between two groups in VAS (p<.01), trunk flexibility (p<.05) and except KODI. Conclusions: Our results indicate that conventional physical therapy with the hip mobilization may be useful for improving chronic low back pain patient.

Objective : The aim of this study is to investigate the effectiveness of ShinBaro Pharmacopuncture in the treatment of patients with Lumbar spine Herniated Nucleus Pulposus. Methods : We investigated 20 cases of patients with lumbar disc herniation and devided into two groups. Experimental group were treated with ShinBaro Pharmacopuncture with integrated package treatment and control group were treated the same therapies without ShinBaro Pharmacopuncture. To evaluate the treatment effects of two groups, we used numeric rating scale(NRS), oswestry disability index(ODI). Results : In NRS of lumbar and sciatica pain and ODI, that of experimental group was much more improved than control group, and decrement of NRS of lumbar pain showed statistical significance along with the duration of treatment. Conclusions : ShinBaro Pharmacopuncture was thought to be effective for relieving symptoms of lumbar spine herniated nucleus pulposus, although further study is needed.

This research aims to perceive the present state of science experimental education practiced in middle school and also to improve the laboratorial environment. Accordingly, this study surveyed 297 middle school science teachers in Seoul to examine the risks and accidents occurred during lab sessions, the conditions of chemical waste disposal, and whether or not teacher's manual clearly states cautions on toxic chemicals. About 70%(69.6%) of science teachers were highly concerned about risks and toxicity of chemicals used in classes, 59.9% experienced actual accidents, and 83.2% were anxiety of incidents caused by chemicals. Besides, 55.2% of science teachers answered that they have little knowledge about caring noxious chemicals used in lab sessions. So it turns out that they need more specific education on handling toxic chemicals. More than one third(36.7%) answered that they disposed of chemical waste water without any special care or kept it in the lab after experiments. The number of chemicals as well used in middle school curriculum is increasing as grades gets higher toxic chemicals. However, there are few teachers' manual covering how to handle noxious chemicals. Therefore, in middle school curriculum the number of poisonous chemicals should be minimized as much as possible, and in case the toxic chemicals have to be used, teacher's guide book should state precautions on handling chemicals in detail. Also government should make it obligatory on schools to instate ventilator for chemical waste, or to transport the waste to proper disposal systems.

The purpose of this study was to determine whether aromatherapy massages with manual lymph drainage (MLD) are significantly more effective than sham massages with MLD in reducing edematous limb volume in lymphedema. This study was performed on 46 patients who had developed unilateral upper or lower lymphedema. Twenty-three patients served as the experimental group and were treated with complex decongestive physiotherapy (CDP) applications including aroma massages with MLD, multi layered compression bandages, remedial exercises and skin care. Twenty-three patients in the control group were treated with CDP applications including sham massages with MLD, bandages, exercises and skin care. Patients undergo a therapy program once a day; 5 days a week for 2 weeks. Percentage excess volume (PEV) and body mass index (BMI) were recorded before and after treatment. PEV and BMI were significantly decreased before and after treatment in the experimental as well as in the control groups (p<.05). However, the percentage excess volume and BMI were not significantly improved after treatment between the two groups (p>.05). This study there suggests that aroma massages is not effective in the edema of patients with lymphedema.

Background: The purpose of this study was to examine the effects of a multi-modal exercise program for patients with chronic low back with respect to pain intensity, trunk muscle strength and Oswestry disability index. Methods: Thirty patients with chronic low back pain were recruited and divided equally into two groups. The multi-modal training program comprised a series of exercises such as warm-up, stabilization exercises, stretching, endurance exercises, and cool down whereas the control group performed only stabilization exercises. The both group spent an equal amount of time performing 60 minutes per day, three times per week, for five weeks. Results: The experimental group demonstrated statistically significant improvements in range of motion, trunk muscle strength, the visual analogue scale, and the Oswestry Disability Index (p<.05). Intergroup comparison showed a statistically significant difference in the range of motion of the lumbar spine and the degree of disability in the experimental group. Muscle strength and pain were statistically significant in both groups. Conclusion: The multi-modal exercise program is effective for patients with chronic low back pain, as it reduces lower back pain, increases trunk muscles strength, and decrease the potential for becoming disabled.

Background: Patellofemoral pain syndrome (PFPS) is common knee disorder encountered in clinical: notably, altered hip biomechanic may contribute to PFPS. In this study, We investigated the effects of hip joint mobilization on pain, balance, and gait in patients with PFPS. Methods: Patients were randomly assigned to a control group (n=18) or an experimental group (n=20). Both groups received exercise therapy thrice a week for 4 weeks. The experimental group performed additional hip joint mobilization thrice a week for 4 weeks. Measurement were obtained in each patient pre-intervention and post-intervention (after 4 weeks). Results: The assessed items included the visual analog scale (VAS), one leg standing test (OLS), timed up and go test (TUG), and the 10m walk test (10MWT). Post-intervention assessment showed significantly improved results in both groups (p<.01). A significant intergroup difference was observed only in the results of the 10MWT (p<.05). Conclusion: Our results indicate that hip joint mobilization with exercise therapy may be useful to improve PFPS.
