Objectives The purpose of this study was to compare the effects between physical play and block play on young children’s motor ability, cognitive ability, sociality, and spatial ability. Methods Thirty young children were included in this study as the subjects, and their average age was 57.76 (SD=3.31) months. Experimental group1 and experimental group2 were selected randomly. Experimental group1 was applied in physical play and Experimental group2 was applied in block play for 4weeks. ‘Motor Proficiency Test for Young Children,’ ‘K-WIPPSI-Ⅳ’, ‘The Bronson Social and Task Skill Profile’, ‘Children’s mathematical ability test(spatial ability)’ were used in collection of data, and t-test for analyzing them. Results As the results, the scores of the physical play group's motor activity and sociality were significantly higher than the scores of the block play group. On the other hand, there was no significant difference between the two groups in overall cognitive ability, but it was found that the physical play group significantly improved than the block play group in verbal comprehension, fluid reasoning, and working memory, which are sub-area of cognitive ability. There was no significant difference between the two groups in the overall spatial ability, but it was found that the block play group significantly improved than the physical play group in the figure comprehension, a sub-area of the spatial ability. Conclusions The results of this study showed that physical play was more effective than block play in enhancing motor ability, sociality, and cognitive ability. It was found that block play enhances children's spatial ability more effectively than physical play. This reveals that children's physical play and building play were positive for children's development, and suggests that there is more effective play in a specific developmental area. 목적 본 연구의 목적은 신체놀이와 쌓기놀이가 유아의 운동능력, 인지능력, 사회성, 공간능력에 미치는 효과를 비교 분석하는데 있다. 방법 본 연구대상은 만 4세 반에 재원중인 유아 총 30명이었으며 평균월령은 57.76개월(SD=3.31)이었다. 실험집단1과 실험집단2를 무선으로 선정한 후 실험집단1에는 신체놀이를 실험집단2에는 쌓기놀이를 4주간 처치하였다. ‘운동능력척도(MPTYC)’, ‘K-WIPPSI-Ⅳ’, ‘Bronson의 사회과업 기술척도’, ‘유아그림수학능력 검사(공간능력)’ 검사 도구로 자료를 수집하였다. 수집된 자료는 t-검증으로 효과를 분석하였다. 결과 신체놀이 집단이 쌓기놀이 집단보다 운동능력, 사회성에서 유의미하게 증진된 것으로 밝혀졌다. 한편, 전체 인지능력에서 두집단 간의 유의미한 차이는 없는 것으로 나타났으나, 인지능력의 하위영역인 언어이해, 유동추론, 작업기억에서 신체놀이 집단이쌓기놀이 집단보다 유의미하게 증진된 것으로 나타났다. 전체 공간능력에서 두 집단 간의 유의미한 차이는 없는 것으로 나타났으나공간능력의 하위영역인 도형에서 쌓기놀이 집단이 신체놀이 집단보다 유의미하게 증진된 것으로 나타났다. 결론 본 연구의 결과는 신체놀이가 쌓기놀이보다 운동능력, 사회성, 인지능력을 증진시키는데 더욱 효과적인 것으로 나타났다. 유아의 공간능력은 쌓기놀이가 신체놀이보다 더욱 효과적으로 증진시키는 것으로 나타났다. 이는 유아의 신체놀이와 쌓기놀이가 유아의발달에 긍정적임을 밝히고, 특정 발달영역에 더욱 효과적인 놀이가 있음을 시사한다.

Purpose: This study compared the radiographic and clinical outcomes of simultaneous bilateral short scarf osteotomy with those of unilateral short scarf osteotomy in hallux valgus patients. Materials and Methods: The authors undertook a retrospective chart and radiographic review between January 2015 and June 2017 to identify 15 patients (30 cases, group A) who underwent a simultaneous bilateral short scarf osteotomy. The patients were matched with 30 patients (30 cases, group B) with a unilateral short scarf osteotomy. No significant preoperative differences were observed between the two groups in terms of age, gender, American Orthopaedic Foot and Ankle Society (AOFAS) hallux score, and radiographic parameters. The clinical and radiographic follow-up was carried out at three months and one year. Results: Hallux valgus angles in groups A and B were reduced from the mean preoperative values of 32.5° and 34.7° to 12.5° and 12.2° at 12 months, respectively. The first-second intermetatarsal angles in groups A and B were also reduced from the mean preoperative values of 14.2° and 16.5° to 7.4° and 7.3° at 12 months, respectively. No significant inter-group differences in radiographic outcomes were observed. After three months, the patients in group A reported significantly worse mean pain and functional scores than group B. The mean AOFAS hallux score was higher in group B at the three-month follow-up, but this difference disappeared at the one-year followup. Conclusion: Simultaneous bilateral surgery can be offered to patients with a hallux valgus deformity requiring correction. On the other hand, they should be informed of the long recovery period.

통신, 센서, 인공지능 등의 기술 발전으로 인해 스마트 팩토리 구축이 진행되고 있다. 스마트 팩토리는 기존의 자동화 공정에서 생산되는 데이터를 대상으로 기계 학습과 같은 지능화 기술을 활용해 효율적인 공정 제어를 목표로 한다. 스마트 팩토리로의 구축으로 인해 생산성이 높아지지만 비용도 높아진다. 따라서 소규모 업체들은 스마트 팩토리로 단계별 전환이 효율적이다. CNC 절단기 기반의 소규모 스마트 팩토리 구축을 위해서 본 논문에서는 기존 제조 장비의 데이터를 수집, 모니터링 및 제어할 수 있는 원격 제어 시스템을 제안한다. 원격 제어 시스템의 구조 및 설계와 효율적인 센싱 데이터 전송 방법 등을 제시하였다. 실현 가능성을 검증하기 위해 CNC 절단 장비를 대상으로 시스템을 구현하였고 기능을 검증하였다. 성능 평가를 위해 모니터링 웹 페이지 접속시간을 측정하였고, 구현된 시스템이 사용 가능한 수준이라는 것을 확인하였다. The technological advances such as communication, sensor, and artificial intelligence lead smart factory construction. Smart factory aims at efficient process control by utilizing data from the existing automation process and intelligence technology such as machine learning. As a result of constructing smart factory, productivity increases, but costs increase. Therefore, small companies try to make a step-by-step transition from existing process to smart factory. In this paper, we have proposed a remote control system that support data collection, monitoring, and control for manufacturing equipment to support the construction of CNC cutting machine based small-scale smart factory. We have proposed the structure and design of the proposed system and efficient sensing data transmission scheme. To check the feasibility, the system was implemented for CNC cutting machine and functionality verification was performed. For performance evaluation, the web page access time was measured. The results means that the implemented system is available level.

Purpose: In this study, children with cerebral palsy were treated for 8 weeks using horse riding trunk proprioception, stability and posture to investigate the effect of hippotherapy in the field of physical therapy. Methods: A total of 18 subjects were divided into an experimental group treated by horseback riding and a control group. Both groups were evaluated pre- and post-treatment. Trunk proprioception was measured three times in the sitting position with their eyes and ears closed to reach the target position the angle error of the mean was calculated. Trunk stability was measured using a forceplate and the data were used to calculate the postural sway path & postural sway velocity. Posture was evaluated using the Posture Assessment Scale (PAS). Results: After hippotherapy, the experimental group showed a significant improvement in trunk proprioception, stability and posture (p<0.05), but the control group improved in posture only (p<0.05). Trunk proprioception, stability and posture was significantly different between the two groups (p<0.05). Conclusion: Eight weeks of hippotherapy is effective in improving trunk proprioception, stability, and posture. Research using this therapy should be studied further as a possible new therapeutic approach in the field of physical therapy.

The purpose of this study was to apply Case-based learning, as a teaching method, to some movement education classes for early childhood pre-service teachers. The study also explored its effects on their teaching efficacy and expertise in movement education. The subjects of this six week study were 164 second year pre-service teachers at a two year college. Half of them joined the experimental group that used Case-based learning, and the other half was the comparison group that used a traditional method of lecture and workshops. For the collected data, the subjects’ teaching efficacy, belief, and professionalism regarding movement education and t-test were used in the analysis. Post-test scores revealed statistically significant differences between the experimental group and the comparison group. Specifically, the scores for teaching efficacy, belief, and professionalism of the pre-service teachers in the experimental group were significantly higher than those in the comparison group. We conclude that Case-based learning is one of the most effective methods for teaching early childhood pre-service teachers movement education, and it is expected to make a substantial contribution to the early childhood movement education field. 본 연구는 유아교사양성과정의 유아동작교육수업에서 사례기반학습을 적용하여 예비유아교사의 유아동작교육 교수효능감과 유아동작교육 전문성에 미치는 효과를 분석하는데 목적이 있다. 본 연구의 연구대상은 서울 소재 전문대학 유아교육과 2학년 학생 164명(실험집단 82명, 비교집단 82명)이었다. 무선으로 선정된 두 집단 중 실험집단에는 사례기반학습을 적용하였으며, 비교집단에는 강의식수업과 워크숍을 6주에 걸쳐 적용하였다. 연구자료는 ‘동작교육 교수효능감 도구’, ‘동작교육 전문성 도구’를 통해 수집하였으며, 수집된 자료는 t검정을 통해 효과를 분석하였다. 연구결과 실험집단의 예비유아교사가 비교집단의 예비유아교사보다 유아동작교육 교수효능감, 유아동작교육 전문성의 사후검사 점수가 유의하게 높은 것으로 나타났다. 이러한 연구결과를 통해 유아동작교육에서 예비유아교사의 동작교육 실천능력을 증진시키는데 사례기반학습이 효과적인 방안이라고 할 수 있으며, 더 나아가 실제 교육현장에서 유아동작교육 내실화의 도모를 기대할 수 있다.
