Objectives The aim of this study is to develop diagnostic and assessable questionnaires for cervical movement system impairment syndromes. Methods We reviewed the previous study and literature, and organized various checkable items for differential diagnosis of four different cervical movement system impairment syndromes. Next, we selected items which can be developed as questionnaire items. Finally, we conducted a face validity study with twelve Korean medical doctors and carried out survey research to evaluate the importance score of the items with three experts. Results We developed a diagnostic and assessable questionnaire as follows: 9 items for cervical extension syndrome; 5 items for cervical flexion syndrome; 9 items for cervical rotation syndrome. By conducting 2 rounds of survey research, we were able to bridge the differences in the importance score of each item. Conclusions A questionnaire for the diagnosis and assessment of movement system impairment syndromes was developed. This questionnaire holds promising applications for objective diagnosis and assessment of cervical movement system impairment syndromes. This tool may also be used for detecting the sub-health status of musculoskeletal systems.

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 research attempts to describe and explain the development of Korean environmental movement. It finds that the emergence of Korean environmental movement was constrained by the authoritarian nature of Korean politics. In 1970s, environmental movements were primitive and were not organized ones. With the wake of democratization in the 1980s, Korean environmental movement began to get some momentum. And in the 1990s, environmental movement to save clean water has achieved some success in certain areas. However, the emphasis on the growth of local economy in the age of local autonomy system has brought heavy degradation of local environment. The coming of the phenomena of Globalization and Cyber-Age has brought positive effects on Korean environmental movement.

The purpose of this study was to examine the effect of fabric movement on wrinkle recovery in a clothing care system and to propose an algorithm to improve wrinkle removal performance by adjusting fabric movements. With an increase in the reciprocating speed of the movement system, the number and amplitude of curves on the fabric also increased. This allowed the fabric to be applied to a larger tension, resulting in better wrinkle removal performance at higher speeds. However, even at high reciprocating speeds, wrinkles could not be removed effectively because of nodes at a few specific locations. Based on the results of fabric movement and wrinkle recovery, a complex movement algorithm was proposed with a mixture of various reciprocation speeds. It showed a 41%p (24%→65%) improvement of wrinkle recovery when compared with the conventional algorithm that showed simple fabric movement at 180 rpm. This was because the positions of nodes and antinodes changed continuously and the force by the reciprocating motion could be applied evenly to the fabric.

Unlike a still body in a photograph, the concept of time applies to a moving body wearing clothes. Clothes change shape according to movement, and multidimensional formative observation elements are required to perceive this. Thus, the purpose of this research is to develop a system for observing body movements and clothing. This experimental study was designed based on embodiment research. The first stage of the study derived body movement and clothing observation items from theory. In the second stage, 11 fashion personnel participated in experimental research to verify the observation items and identify those that needed correction or supplementation. The results showed that body movement and clothing observation items can be classified as follows: large moving bodies, moving clothes, body and clothes movement, and body and clothes space. The observation system for body movement and clothes presented can be used to construct the formation of moving clothes.

A quantitative non-contact multi-point measurement system is proposed to the measurement of three-dimensional movement of floating vessels by using digital image processing. The instantaneous three-dimensional movement of a floating structure which is floating in a small water tank is measured by this system and its three-dimensional movement is reconstructed by the measurement results. The validity of this system is verified by position identification for spatially distributed known positional values of basic landmarks set for the camera calibration. It is expected that this system is applicable to the non-contact measurement for an unsteady physical phenomenon especially for the measurement of three-dimensional movement of floating vessels in the laboratory model test.

Proprioception means the ability to perceive the sensation of position and movement of body. As it is transmitted to central nervous system and used in feed-back or feed-forward motor control, proprioception allows us to keep our normal movement and normal balance activity. However, the conditions such as injury, disease, aging and fatigue can damage the proprioceptiive sensation of position, movement and lead to a functional impairment and additional damages in musculoskeletal system, because they alter the amount of proprioceptive ability that transfer into the central nervous system. The purpose of this study was to identify the definition and the function of proprioception, to look into variations in injury, disease, aging and fatigue that can be easily met in clinical application and eventually to provide valuable aid for assessment and treatment.

Control devices perform various works for us in many areas. The device is being utilized for precision movement of certain object. In as much as control devices are activated by means of motors, motor control is important.[1][2] Generally, servo motors capable of precision control are more frequently used than DC motors. Use of 3 motors allows 3- way movement. Medical controllers for surgical operation require high precision. [3][4][5][6] AX-12, a servo motor can realize various types of movement. AX-12 can be easily manufactured in the form of a robotic arm and has features that MCU and its peripheral circuits are simple. For precision movement, 3 motors can be controlled by use of a single joystick and 2 buttons, with movement angles being adjusted by having preset values in the program changed.[7][8] By virtue of this study, we have realized small precision robotic arm system utilizing single joystick and 2 buttons. This system can control the robotic arm in the direction desired by the user. The system has been designed such that a joystick controls 2 motors with the remaining motor being controlled by a button. Single MCU is tasked with both control and movement.[9] We have shown precision robotic arm system in the Figure contained in the conclusion part and made reference to results of analysis in there. It has also been demonstrated that the system can be utilized in the industry.[8]

Objectives: Sahrmann, an American physical therapist, has developed a set of movement-related diagnoses on musculoskeletal pain syndromes (MPS). We reviewed articles for studies of objectification and quantification of Oriental medicine diagnosis system about MPS. Methods: The authors reviewed a total of 12 studies found on PubMed to obtain movement system impairment (MSI)-based classification categories. Results: The MSI system has been developed for objectification and quantification of physical therapists' MPS diagnoses. The MSI system of classification is based on the basic premise that loss of precise movement is the result of specific repetitive movements and positions in everyday life. The MSI system defines 8 categories in the shoulder region, 5 in the lumbar region, and 7 in the knee region. Treatment involves (1) educating the person about the specific directions of alignment and movement that appear to be contributing to the musculoskeletal problem, (2) modifying the direction - specific alignment and movement patterns during daily activities, and (3) exercises to address the impairments. Conclusions: The authors propose that MSI studies could help to advance an Oriental medical diagnosis system on musculoskeletal pain syndromes, because MSI shares similarity with Oriental medicine in terms of holism, views of constant motion, and mi-byung (subhealth) treatment.
