Objective : This study verifies the effects of sensory integrative (SI) therapy on vestibular- and proprioceptive sensory (BPS) processing ability of a child with Asperger Syndrome (AS). Method : A boy who is 11 years and 2 months old took the Functional Independence Measure for Children (Wee-FIM), Canadian Occupational Performance Measure (COPM), Short Sensory Profile, Bruininks-Oserestky Test of Motor Proficiency-2 (BOT-2), and Test of Playfulness (ToP) for the baseline. The child participated in 3 evaluation sessions and 8 therapy sessions based on the AB research design. Duration of each session is 50 min and the therapy session is divided into 40 minutes for treatment and 10 minutes for evaluation. Since the vestibular sense and proprioception build up one's ability of postural control, several tests were employed to evaluate the child' postural control as outcome measure; distance from front leg of chair to heel of the child with sitting (C-H distance), angle between trunk and thigh (hip joint angle) with sitting, and the 'prone-extension posture' which is a subtest of Clinical Observation of Motor and Postural Skill (COMPS) to examine postural control embodied with integration of reflex and BPS processing. Result : During the therapy, average data of the C-H distance is decreased from 27.33cm to 11.69cm, average data of the hip joint angle is also decreased from $43.3^{\circ}$ to $20^{\circ}$, and average time for the prone-extension posture is increased from 13.15seconds to 24.84seconds. Conclusion : This result indicates that the ability to postural control in sitting and to maintain the prone-extension posture can be improved by sensory integrative therapy, with enhanced BPS processing.

Last-Mile delivery optimization plays a key role in the urban supply chain operation, which is the most expensive and time-consuming and most complicated part of the whole delivery process. The urban consolidation center (UCC) is regarded as a significant asset for supporting customer demand in the last-mile delivery service. It is the key benefit of UCC to improve the load balance of vehicles and to reduce the total traveling distance by finding the better route with the well-organized multi-leg vehicle journey in the urban area. This paper presents the model using multiple scenario analysis integrated with mathematical optimization techniques using Geographic Information System (GIS). The model aims to find the best solution for the distribution network consisted of DC and UCC, which is applied to the case of Ulaanbaatar Mongolia. The proposed methodology integrates two sub-models, location-allocation model and vehicle routing problem. The multiple scenarios devised by selecting locations of UCC are compared considering the general performance and delivery patterns together. It has been adopted to make better decisions the quantitative metrics such as the economic value of capital cost, operating cost, and balance of using available resources. The result of this research may help the manager or public authorities who should design the distribution network for the last mile delivery service optimization using UCC within the urban area.

In this study, we analyzed 24 pieces ($4{\times}3{\times}2$) of pork jerky produced using raw meat and we then randomly assigned the hind leg meat to a treatment group. In addition, the effects of storage according to aerobic plate counts and sensory evaluation on pork jerky were examined. Form the results, We found that volatile basic nitrogen (VBN) content and aerobic plate counts of pork jerky gradually increased with increased storage time, ; moreover, there was a significant difference between the treatment groups and the control group (p<0.01). However, the counts did not increase as significantly in the ginseng powder group (B), as compared to the ginger powder group (A) (p<0.05). The sensory evaluation of pork jerky peaked during the second week of storage in all treatment groups, after which these characteristics gradually decreased (p<0.05). In addition, these characteristics were generally higher in the control group, compared to the treatment groups. When comparing the ginseng powder addition group (B) and ginger powder-addition group (A), only color was significantly higher in the ginger powder group. Based on this study as well as previous studies, storage of pork jerky significantly affects the sensory evaluation of raw pork. Ginger powder may have a more beneficial effect than other treatments on the sensory evaluation. Additionally, in all treatment groups, sensory characteristics were significantly higher in the ginger treated groups than in those of the ginseng-treated groups.

This study was conducted for improvement of meat quality in broiler chcikens. Birds were fed basal diet(control), ferritin, illite, betafin, or wood vinegar counting broiler feed according as broiler growth stage. Birds fed with basal diet, which was distributed under the best environmental condition, were more weight gain than other groups reared under same environmental condition. In the mean weight gain, the ferritin-group showed the highest and the illite-group showed the lowest among the feed additive groups; therefore, the effect of feed requirement change in odor reduction in illite and methyl saving of betafin was lower than those of other feed additives along to pass rear time. Meat quality was appraised by National Livestock Research Institute of RDA. Except the control-group, that had the best feed conversion ratio, the cooking loss of the illite-group was the biggest among groups although the illite-group chickens had a good water hold capacity. Therefore, illite is not good for making merchandise by reason that group chickens get reduction carcass weight after slaughter. On the other hand, the ferritin-group got the highest point of shear stress, cooking loss, and crude fat level. That group showed the best appraise in both breast and leg of sensory test in company and also feed conversion ratio was the highest among feed additive groups. As a result, the ferritin-group might use for making new merchandise among the feed additive groups.

Purpose : Plantar surfaces, calcaneal area, and region of Achilles insertion, which are extremely related with weight-bearing area and shoes application, must be reconstructed with glabrous and strong fibrous skin. Numerous methods of reconstructing defects of these regions have been advocated, but the transfer of similar local tissue as a cutaneous flap with preservation of sensory potential would best serve the functional needs of the weight-bearing and non-weight-bearing surfaces of this region. Therefore it is recommended to use the limited skin of medial surface of foot that is similar to plantar region and non-weight-bearing area. In this paper we performed the medial plantar flap transfered as a fasciocutaneous island as one alterative for moderate-sized defects of the plantar forefoot, plantar heel, and area around the ankle in 25 cases and report the result, availability and problem of medial plantar flap. Materials and methods : We performed proximally based medial plantar flap in 22 cases and reverse flow island flap in 3 cases. Average age was $36.5(4{\sim}70)$ years and female was 3 cases. The causes of soft tissue defect were crushing injury on foot 4 cases, small bony exposure at lower leg 1 case, posterior heel defect with exposure of calcaneus 8 cases, severe sore at heel 2 cases, skin necrosis after trauma on posterior foot 4 cases, and defect on insertion area of Achilles tendon 6cases. Average follow up duration was 1.8(7 months-9.5 years) years. Results: Medial plantar flaps was successful in 22 patients. 18 patients preserved cutaneous branches of medial plantar nerve had sensation on transfered flap but diminished sensation or dysesthesia. At the follow up, we found there were no skin ulceration, recurrence of defect or skin breakdown in all 18 patients. But there was one case which occurred skin ulceration postoperatively among another 4 cases not contained medial plantar nerve. At the last follow up, all patients complained diminished sensation and paresthesia at medial plantar area distally to donor site, expecially with 4 patients having severe pain and discomfort during long-time walking. Conclusion : Medial plantar island flap based on medial plantar neurovascualr pedicle have low failure rate with strong fibrous skin and preserve sensibility of flap, so that it is useful method to reconstruct the skin and soft tissue defect of foot. But it should be emphasized that there are some complications such like pain and paresthesia by neuropraxia or injury of medial plantar nerve at more distal area than donor site. We may consider that medial plantar flap have limited flap size and small arc of rotation, and require skin graft closure of the donor defect and must chose this flap deliberately.

This study presents a gait analysis method (including time series analysis) using a smart insole as an objective and quantitative evaluating method after lumbar scoliosis surgery. The participant is a degenerative lumbar scoliosis patient. She took 3-min-gait-test four times(before and 8, 16, and 204-days after surgery) and 6-min-gait-test once(204-days after surgery) with smart-insoles in her shoes. Each insole has 8-pressure sensors, an accelerometer, and a gyroscope. The measured values were used to compare the characteristics of gait before and after surgery. The analysis showed that all of the patient's gait parameters improved after surgery. And after 6 months, the gait was more stable. However, after long walk, the swing duration of one leg was slightly shorter than that of the other again. It was a preclinical problem that could not be found in the visual examination by the practitioner. With this analysis method we could evaluate the improvement of patient quantitatively and objectively. And we could find a preclinical problem. This analysis method will lead to the studies that define and distinguish gait patterns of certain diseases, helping to determine appropriate treatments.

As it is changing into aging society, rehabilitation, welfare and sports industry markets are being expanded fast. Especially, the field of vital signals interface to control welfare instruments like wheelchair, rehabilitation ones like an artificial arm and leg and general electronic ones is a new technology field in the future. Also, this technology can help not only the handicapped, the old and the weak and the rehabilitation patients but also the general public in various application field. The commercial bio-signal measurement instruments and interface systems are complicated, expensive and large-scaled. So, there are a lot of limitations for using in real life with ease. this thesis proposes a wireless transmission interface system that uses EMG(electromyogram) signals and a control module to manipulate hardware systems with portable size. We have designed a hardware module that receives the EMG signals occurring at the time of wrist movement and eliminated noises with filter and amplified the signals effectively. DSP(Digital Signal Processor) chip of TMS320F2808 which was supplied from TI company was used for converting into digital signals from measured EMG signals and digital filtering. We also have used PCA(Principal Component Analysis) technique and classified into four motions which have right, left, up and down direction. This data was transmitted by wireless module in order to display at PC monitor. As a result, the developed system obtains recognition success ratio above 85% for four different motions. If the recognition ratio will be increased with more experiments. this implemented system using EMG wrist direction signals could be used to control various hardware systems.

Purpose: Ligament reattachment technique using a suture anchor appears to show satisfactory functional outcomes and mechanical stability compared with conventional bone tunnel technique. This study was prospectively conducted in order to evaluate functional outcomes of modified Brostrom procedures using the suture bridge technique for chronic ankle instability in athletes. Materials and Methods: Twenty eight athletes under 30 years of age were followed for more than two years after undergoing the modified Brostrom procedure using the suture bridge technique. Functional evaluation consisted of the foot and ankle outcome score (FAOS), foot and ankle ability measure (FAAM) score. Range of motion and time to return to exercise were evaluated using a periodic questionnaire. Talar tilt angle and anterior talar translation were measured through stress radiographs for evaluation of mechanical stability. Results: FAOS improved significantly from preoperative mean 59.4 points to 91.4 points (p<0.001). Daily living and sport activity scores of FAAM improved significantly from preoperative mean 50.5, 32.5 points to 94.8, 87.3 points, respectively (p<0.001). Talar tilt angle and anterior talar translation improved significantly from preoperative mean $16.8^{\circ}$, 13.5 mm to $4.2^{\circ}$, 4.1 mm at final follow-up (p<0.001). Times to return to exercise were as follows: mean 10.2 weeks in jogging, 15.4 weeks in spurt running, 13.1 weeks in jumping, 11.5 weeks in walking on uneven ground, 9.1 weeks in standing on one leg, 7.2 weeks in tip-toeing gait, 8.4 weeks in squatting, and 10.6 weeks in descending stairs. Conclusion: Modified Brostrom procedure using the suture bridge technique showed satisfactory functional outcomes for chronic ankle instability in athletes. Optimal indication and cost-effectiveness of the suture bridge technique will be studied in the future.
