This study aimed to produce sensors for measuring thigh motor skills. A textile stretch sensor was manufactured using a CNT(Carbon Nano Tube) 0.1 wt% water SWCNT(Single-Walled Carbon Nano Tube) solution, and different designs were applied to increase the sensitivity of the sensor, and different GF(Gauge Factor) values were compared using UTM devices. The same design was applied to fabrics and weaves to observe changes in performance according to fibrous tissue, and the suitability of sensors was determined based on tensile strength, elongation, and the elongation recovery rate. Sensitivity was found to vary depending upon the design. Thus the manufactured sensor was attached to a pair of fitness pants as a prototype, divided into lunge position and squat position testing, and the stretch sensor was used to measure thigh movements. It was shown that stretch sensors used to measure thigh motor skills should have light and flexible features and that elongation recovery rates and tensile strength should be considered together. The manufactured stretch sensor may be applicable to various sports fields that use lower limb muscles, wearable healthcare products, and medical products for measuring athletic ability.

Purpose: The aim of this study was to investigate correlations between the Functional Movement Screen (FMS), pain, and performance ability in professional fencing players. Methods: Fifty-six athletes participated in this study. The pain group included those who had a score on a pain-related Visual Analogue Scale (VAS) of ${\geq}$20 and an Oswestry Disability Index (ODI) score ${\geq}$10). In the non-pain group, these scores were: VAS(<20), ODI(<10). The VAS and ODI were used to measure pain throughout the study. Performance ability included motor function of the lower extremities (as assessed by a Modified Functional Index Questionnaire, MFIQ), dynamic balance (Balance system, BS and Posture med, PM), flexor and extensor muscle strength of the lumbar region was recorded as maximal isometric strength. Results: Among athletes who had pain, 5 of 15(33.33%) showed impaired functional movement. Conversely, only 2 of 41(4.88%) of those who had no pain showed such impairment (FMS ${\leq}$14score). The athletes who had pain and who had an FMS score above 14 (10/56; 17.86%) showed a significantly higher score for extensor muscle strength of the lumbar compared with those with pain and an FMS score below 14 (5/56; 8.93%) were significant correlations between the FMS and pain (r=-0.40 to -0.42, p<0.01), the MFIQ (r=-0.33, p<0.05), dynamic balance (r=-0.27 to -0.40, p<0.05-0.01), muscle strength of the lumbar (r=0.27 to 0.29, p<0.05). Stepwise multiple regression analysis showed that the dynamic balance score (${\beta}{\beta}$=-0.41) had slightly more power in predicting FMS score than pain, motor function of lower extremity, or muscle strength. Conclusion: The FMS was significantly associated with values of pain, motor function of the lower extremities, dynamic balance, and muscle strength of the lumbar. However the FMS appears to lack relevance and reasonable evidence to suggest that it is an acceptable measurement tool for functional movement analysis.

Purpose : The purpose of this research was to investigate the effects of barefoot walking on the sandy beach on pain intensity, disability, motor function, sleep satisfaction, and quality of life in the elderly with low back pain (LBP). Methods : A single-blinded randomized controlled trial was conducted involving 32 elderly with LBP who underwent sand walking barefoot (intervention, n=16) or with sneakers (control, n = 16). Both walking methods were carried out for 30 minutes per day, three times a week for four weeks. Pain intensity and disability were assessed using the visual analog scale and Oswestry disability index, respectively. Balance and gait were evaluated using the Berg balance scale and timed up and go test, respectively. Sleep satisfaction was quantified with the Verran and Snyder-Halpern sleep scale. Finally, quality of life was assessed through the WHO quality of life scale's abbreviated Korean version. Results : Compared with the control group, the intervention group showed significant differences in pain intensity (p=.005), disability due to LBP (p=.002), static balance ability (p=.003), dynamic balance ability (p=.002), and sleep satisfaction (p=.017). There was no significant difference in the quality of life between the two groups. Conclusion : Barefoot walking on a sandy beach is significantly effective in improving pain, disability due to LBP, balance ability, and sleep satisfaction in the elderly with LBP. Further studies with larger sample sizes and longer intervention periods must to be conducted to generalize using barefoot walking in LBP management.

본 논문에서는 항만 자동화를 위해 새로이 제안된 리니어 모터 기반 컨테이너 이송시스템에 지능제어기법을 이용하여 그 정밀도를 향상시키고자 한다. LMCTS(Linear Motor-based Container Transfer System)는 스케일의 거대함 때문에 일반 리니어 모터에서 중요시 되지 않는 정지마찰력과 디텐트럭(detent force)이 정밀제어에 큰 문제가 된다. 특히, 컨테이너 적제유무에 따라 시스템 자체가 급격히 변하므로 기존의 PID형 제어기로는 좋은 성능을 얻기 어렵다. 따라서 본 논문에서는 같은 구조를 갖는 두 개의 DR-FNN(Dynamically- constructed Recurrent Fuzzy Neural Network)를 제어기와 에뮬레이터로 구성하여 이러한 문제를 해결하고자 하였다.

PURPOSE: This study examined the differences in the trunk impairment scores according to the levels of the gross motor classification system by evaluating trunk control in children with spastic cerebral palsy using the index of trunk impairment. In addition, the characteristics of trunk control disabilities were investigated according to the cerebral palsy type. METHODS: The subjects were 49 children (mean age 8.57±1.83 years, 11 with hemiplegia, 26 with diplegia, and 12 with quadriplegia) with spastic cerebral palsy levels I to IV under the gross motor function classification system (GMFCS). The coordination and balance of the children with cerebral palsy were evaluated using the index for trunk impairment. Statistical analyses were performed using a Kruskal-Wallis test, and Bonferroni analyses were used as a post-hoc comparison for any significant results. RESULTS: The median of the total scores of trunk impairment was 13 (range, 9-17), which was 56% of the maximum score. The total score of trunk impairment and subscales differed significantly according to the disease severity and type of motor disability. The scores for children with quadriplegia were the lowest compared to children with hemiplegia and diplegia. CONCLUSION: Trunk control function in children with spastic cerebral palsy was reduced, and varied according to the disease severity and types of motor disabilities. The degree of trunk impairment differed from the trunk control ability according to the degree of motor disability of children with cerebral palsy.

무인항공기(Unmanned Aerial Vehicle, UAV)는 짧은 시간 동안 넓은 범위의 정찰이 가능하기 때문에 최근에는 이를 활용한 감시 시스템 연구가 주목을 받고 있다. 넓은 범위를 감시할 때 조종사가 반복적으로 UAV를 비행시키는 것은 운영에 필요한 비용 문제가 발생한다. 감시를 위한 비행경로를 사전에 정의할 수 있다면 이를 기반으로 UAV를 자율 비행시켜 비용 문제를 해결할 수 있다. 전통적인 접근 방법은 GPS를 기반으로 비행할 경로를 다수 개의 모터프리미티브로 정의한다. 하지만, UAV가 감시할 지점이 모터프리미티브에 반영되지 않아 감시가 제대로 수행되지 못하는 문제가 발생한다. 이 논문에서는 감시용 UAV를 자율 비행시키기 위한 모터프리미티브의 구조를 제안한다. 모터프리미티브는 감시 대상을 정확히 기술하기 위해서 자동으로 감시할 지점을 선택하여 생성된다.
