As the accuracy of manufactured goods needed high-accuracy processing has made the efficiency of NC and measurment technology develop, the innovation of machine tools has influence the development of the semi-conductor and optical technology. We can mention that a traction role of the acceleration for the development like that depends on the development of the measurement technics - Stylus instrument method, STM, SEM, Laser interferometer method - which are used for measuring the movement accuracy of machine tools. The movement error factors in movement accuracy are expressed as yaw, roll, and pitch etc. Machining center has 21 movement error factors including of 3 axies joint errors because that has 3 axies and has been measured as the standard of the unloaded condition until now inspite of getting static, dynamic, and servo-gain errors in the case of expending the error range. Therefore, this study tries to measure position accuracy according to loading on the X-Y table of the machining center.

본 연구의 목적은 5.16 군정기 1962년 전라북도가 추진한 "보고가는 마을"운동을 소개하고, 당시의 평가를 통해 우리나라 농촌지역개발 초기의 사업내용과 그 의미가 현재 마을 단위 농촌지역개발과 어떻게 연계되어 오고 있는지를 찾고자 하였다. 이를 위하여 1960년대 잡지, 신문, 보고서 등의 관련 자료를 분석하는 문헌연구를 실시하였다. 1962년도 "보고가는 마을"은 총 4,031개 마을이 조성되었으며, 각 부락의 지도자들은 "농촌의 등불"로 지정되었다. 당시 관련 자료의 재구성을 통해 "보고가는 마을"이 재건국민운동과 지역사회개발사업의 이론적, 행정적 틀 내에 있었고, 신생활운동과 생활개선사업이 실질적인 사업내용으로서, 해방이후 전라북도가 자체적으로 추진한 최초의 농촌지역개발사업이며, 관 주도로 추진된 전국의 모범부락 운동의 시발점임을 확인하였다. 또한 "보고가는 마을"은 시찰과 견학을 위한 일종의 관광부락, 전시부락이었고, '관광마을'이라는 단어가 신문에 등장한 최초의 사업이었다. 본 연구는 국가의 정책을 중심으로 한 지금까지의 농촌지역개발사에서 간과되어 온 미시적인 지방사를 발굴하였다는 측면에서 향후 관련 연구의 기초자료로 활용될 수 있으리라 판단된다.

The purposes of this study are to consider characteristics of 'movement expression' that are not discovered in preceeding design studies in order to suggest 'movement expression' as a design formative principal and to make clothes which follows this idea. For the method of this study I used various literature about 'movement expression' as theoretical background and analyzed modern clothing in which 'movement expression' is expressed by collecting magazines including foreign collections from 1989 to 2004 and searching the internet. The results obtained from this study is as follows. First, clothing in which 'movement expression' is expressed removes monotony and tedium of clothing design, provides visual interest and satisfaction for clothing, and delivers designers' concept effectively by attracting a gaze quickly. And It is suggested a new division of 'movement expression' through analysis of the 'movement expression' expressed in clothing. It included the intentional movement by wearers, which is the 'movement expression' of broader meaning such as changes of form or position by a certain operation and changes of existence or function. This movement is not fixed and repeated but changes continuously. As a result of including the design expressing the intentional movement by wearers, one's own personality can be expressed more effectively. It is presented a design which has changeable movement expression continuously.

In this paper, we provide a development and evaluation method for an archery posture analyzing system, using an inertial sensor. The system was developed using LabVIEW2014 by National Instruments and evaluated using the DTW algorithm. To convert the voltage value of the inertial sensor into a physical value, a coordinate transformation matrix bias was applied. To evaluate the similarity of movement in archery shooting, the DTW distance was calculated and similarity was confirmed based on simple mechanical movement, the same person's shooting movement, shooting movement with another person, and the noise signal. The average similarity comparison results were as follows: simple mechanical movement was 17.05%, the same person's shooting movement was 26.48%, shooting movement with another person was 62.8%, and the noise signal was 328.5%; a smaller value indicates a higher level of similarity. We confirmed the possibility of analyzing the archery posture using 3-axis acceleration of the inertial sensor. We inferred that the proposed method might be important means for assessing shooting skills, evaluation of archer's progress, and finding talented archers in advance.

This paper introduces the movement creation and control technique of an avatar, whose replacement of the user is increasing due to the rapid development of the internet and hardware that generalizes the VR. A 3D avatar´s movement is usually created through the key-framing technique or motion-capture equipment. This paper introduce the production of the avatar´s movement by constructing a articulated avatar whose speed and movement are automatically created by the neural oscillatory network and avatar´s joint is controlled by the use of kinematics and motion editor.

The aim of this study is to investigate the relationship between the object ability, basic movement ability, and mathematical ability of young children. Next, through this study, the influence of young children's object manipulation ability and basic movement ability on mathematical ability was investigated. The subjects of this study were 80 children aged 5 years old. As a research tool, the non-mobile movement and mobile movement, the basic movement development test scale, and the young children's picture-mathematical ability test scale were used. This survey was conducted from October 2018 to January 2019. For data analysis, correlation analysis and hierarchical multiple regression analysis were performed using the spss program. As a result of the study, it was found that there was a significant positive correlation between the non-mobile ability, movement ability, object manipulation ability and mathematical ability of young children. It was found that young children's ability to manipulate objects and non-movement abilities had positive effect on their mathematical abilities. The movement ability of young children had both negative and positive effects on mathematical ability, but it was not found to be statistically significant. This study is meaningful in that it investigated the effects of non-mobile movement, mobile movement ability, and object manipulation ability, which are sub-capabilities of basic movement ability, which had not been investigated so far, on the mathematical ability of young children.

The purpose of this study was to examine spiral way movement of a trunk exerts on the movement ability. The details established to achieve for this article. This examination confirmed the weight, weight/height2 index, ratio of lumbar to pelvic, musculoskeletal quantity, push up for 2 minute, pitch a ball and voluntary isometric contraction with flexion and extension of knee joint of the subjects with spiral direct movement. Healthy eighteen subjects who understand fully the significance of procedure, consented to a plan, without neuromuscular disease were participated in two groups of experiment. The group were a spiral movement(9), rectilinear movement(9). Trunk movement tested 2 sessions of a spiral movement and rectilinear movement with a push up for 2 minute, 5days per a week, for the 4 weeks. This experiment tested 3 times with a sufficient rest for fatigue limitation. An analysis of the results used a paired samples t-test for difference from before and after experiment. The following results were obtained; At an internal change of the body, the musculoskeletal quantity was increased significantly to spiral movement group, but the weight was increased significantly, the musculoskeletal quantity was not significant to rectilinear movement. The movement ability evaluation for a external change was increased significantly in a push up for 2 minute, pitch a ball, isometric contraction with extension of knee joint of a spiral movement group, but a push up for 2 minute was increased significantly in a push up for 2 minute on the abdominal muscle training of a rectilinear movement group. As compared with a rectilinear movement, a spiral movement was more effect by cooperation with nerve and musculoskeletal system and an increase in movement ability was caused by learning acknowledgment, muscular reeducation. These results lead us to the conclusion that a spiral movement of trunk was more effect than a rectilinear movement, the coordination of nerve and musculoskeletal system was of importance of Multi-direction movement. Therefore, A further studies concerning the therapeutic exercise intervention and active-dynamic analysis could enhance the development of the most effect on the trunk.

This paper proposes a methodology for the small-displacement-movement of a piston and develops a hybrid control algorithm for the precision position control of a pneumatic rodless cylinder. The pneumatic system uses the voltage-proportional solenoid valves to minimum valve switching since the on/off type valves are create diffculties for accurate position control and induce a lot of valve switching. For the accurate position control a methodology for the small-displacement-movement of the piston is developed and identified experimentally. The main consideration on the development of the hybrid control law is to eliminate a stick-slip phenomenon in the pneumatic control system. This paper addresses these critical issues and presents experimental results for the pneumatic control system.
