The purpose of this study was to identify the structural relationships among the perception of teaching behaviors, self-monitoring, competence, and task persistence of middle school students in physical education classes. A convenience sampling was performed to analyze data collected from 446 students in four middle schools in the Seoul metropolitan area. As a result of the study, first, the autonomous teaching behavior of teachers was found to have a significant impact on the self-monitoring, competence, and persistent task performance of students. Second, controlling teaching behavior among teaching behaviors had no significant impact on students' self-monitoring, competence, and task persistence. Third, self-monitoring was found to have a significant impact on the students' cognition of competence and task persistence. Fourth, competence did not have a significant impact on predicting task persistence. Lastly, in the relationship between teaching behaviors and task persistence, self-monitoring and competence had mediating effects on teachers’ autonomous teaching behavior and students’ task persistence. In short, compared to the controlling teaching behavior, teachers with greater autonomy in teaching were more effective in improving students’ academic achievement. Meanwhile, self-monitoring and competency also improved with autonomous teaching behavior, which hence had a significant correlation with persistent task performance. These findings highlight the need for teachers to place greater emphasis on autonomous teaching behavior than on controlling teaching behavior. In addition, students’ improved self-monitoring based on their tendency for cognitive academic achievement and competence related to the perception of functional enhancement may also be effective in their persistent task performance. Therefore, the results of this study are expected to provide useful information to understand students' learning behaviors.

In this study, we investigate the effects of slots installed on the tip of a rotor blade on aerodynamic characteristics. The slots weaken the strength and spatial coherence of the tip vortex at early vortex age and accelerate the dissipation of the generated tip vortex. Accordingly, the turbulence intensity of the rotor wake is reduced at both near and far wake, which leads to a reduction in broadband noise. Tonal noise is also reduced by mitigation of tip vortices, but tonal noise reduction is limited to a narrower range of azimuths than broadband noise due to the extinction of tip vortices. In addition, slots reduce both mean thrust and thrust fluctuations. Reduction in thrust fluctuations leads to a reduction in blade loading noise, resulting in a reduction in tonal noise.
소유권체제 발전에 따른 「소비자생활협동조합법」 법제화 과정 분석
신이수 국회입법조사처 2020 입법과 정책 Vol.12 No.2
Cooperatives, one of the Social Economy organizations, has been increasing after the legalization of ‘ Framework Act on Cooperatives ’ in 2012. But there has been some legal frameworks and acts before that legalization and the one is ‘ Consumer Cooperatives Act. ’ The Act was legalized in 1999, and there was a try for an amendment concerning about the conduct of mutual-aid or cooperative insurance, the change of the ministry concerned, and so on. However, until now, there is little improvement, so that it asks for analyzing why the conflictual situation does not improve. This thesis asserts that the analysis of the cooperatives ’ common interest, not public interest or publicness which is the dominant perspective of earlier studies or policy implementation, could be critical for illuminating cooperatives ’ practical stand. For this, this thesis apply the property-rights regime for the developments of cooperatives ’ common interest, and explain the regime consists of bundles of property rights. 사회적경제 영역의 주요 조직 형태인 ‘협동조합’은 2012년 「협동조합 기본법」 제정 이후급격한 양적 성장을 경험하고 있다. 하지만 해당 기본법 제정 이전에도 개별법에 근거한협동조합들이 존재했으며, 그중 가장 마지막으로 제정된 법이 「소비자생활협동조합법」이다. 해당 법은 1999년에 제정되었으며, 2010년 1차 개정이 이루어졌으나 현재까지도 공제사업 시행, 주무부처 변경 등의 사안을 두고 개정 논의가 이어지고 있다. 본 글은 「소비자생활협동조합법」의 제정 및 개정 과정, 즉 일련의 법제화 과정을 분석한다. ‘공익(public interest)’ 내지 ‘공공성(publicness)’의 강조로 주목받지 못했던 소비자생활협동조합의‘공동 이해관계(common interest)’에 주목한다. 이를 통해 법제화 과정에서의 소유권체제(property-rights regime) 형성 및 발전 양상을 확인하며, 소유권체제의 수준이 실행 수준-집합선택 수준-헌법선택 수준으로 변화되었음을 보인다.

The aim of this study was to assess quantitative muscle fatigue during isometric and isotonic contractions using a mechanomyography (MMG) and a computational geometry technique known as a convex hull algorithm. Twenty-five male volunteers participated in the experiment. The subjects performed knee flexion and extension exercises on an isokinetic dynamometer. A 3-axis accelerometer (x: longitudinal; y: medial-lateral; z: superior-inferior) was placed on the right rectus femoris muscle. The MMG signal was recorded at a sampling rate of 1 kHz. Each subject performed the maximal knee extension 10 times to determine the 10-repetition maximum torque and maximal isometric contraction at a knee angle of 90o. The results showed that positive correlations were observed between normalized torque and x-direction MMG (linear, r2=0.44), z-direction MMG (linear, r2=0.58), and signal vector magnitude (linear, r2=0.44). The decreases in hull area or volume of MMG signal may result from fatigue due to reductions in motor unit firing rate and increase in muscle thickness. This study evaluated muscular function during fatigue exercises by analyzing the electrical activities of activated skeletal muscle fibers and low-frequency lateral oscillations using accelerometer-based MMG.
지역 기반 사회적경제의 장소성 형성과정 탐색: 서울시 사례연구

본 연구는 지역 내 선순환 경제를 하나의 목표로 삼는 사회적경제 조직이 서울에서 어떻게 주민과 관계를 맺고 지역사회 내에서 토착화 되는지 탐색하였다. 이를 위해 지역 기반의 사회적경제 조직 사례를 통해 사회적경제의 장소성 형성과정의 공통적 특성을 밝히고자 하였으며, 장소성을 구성하는 여러 요소와 다양한 하위단위 분석을 실시하는 임베디드 사례연구(embedded case study)를 진행하였다. 서울시의 5대 권역에 뿌리내린 6개 사회적경제 조직이 대상 사례이며 지역에서 오랜 역사를 지니거나 지역을 기반으로 설립된 조직이 선정되었다. 사례분석 결과 현재위치와 외부관계, 장소기반의 일과 사람, 장소에 필요한 정책제도, 장소를 만들어주는 분위기와 문화, 체험과 경험으로 기억되는 장소, 지역 기반의 장소로 뿌리내림 등 6개의 장소성 속성이 공통적으로 나타났다. 이를 통해 사회적경제 조직이 지역에 깊이 정착할 수 있는 정책 제안과 실행에 있어 필요한 시사점을 제시하였다. This study explored the placefulness of how social economy organizations settled in Seoul. It looked at how social economy organizations affect the region and how they give experiences and memories to residents. In the case of regional-based social economy organization, we explored the common characteristics of the process of forming the placefulness of social economy organizations. Through the embedded case study, various factors and various sub-units were analyzed. The selected cases are six social economy organizations rooted in five major regions of Seoul, and organizations with a long history in the region or established based on the region were selected. As a result of the case analysis, 6 properties of placeness appeared, and 12 dimensions of placeness were revealed. Based on this finding, suggested policies and implications for social economy organizations to settle well in the region.
