Objective: Bilateral movement training is an effective method for upper extremity rehabilitation of stroke. An approach to induce bilateral movement through functional electrical stimulation is attempted. The purpose of this study is to develop an EMG-triggered functional electrical stimulation device for upper extremity bilateral movement training in stroke patients and test its feasibility. Design: Feasibility and Pilot study design. Methods: We assessed muscle activation and kinematic data of the affected and unaffected upper extremities of a stroke patient during wrist flexion and extension with and without the device. Wireless EMG was used to evaluate muscle activity, and 12 3D infrared cameras were used to evaluate kinematic data. Results: We developed an EMG-triggered functional electrical stimulation device to enable bilateral arm training in stroke patients. A system for controlling functional electrical stimulation with signals received through a 2-channel EMG sensor was developed. The device consists of an EMG sensing unit, a functional electrical stimulation unit, and a control unit. There was asymmetry of movement between the two sides during wrist flexion and extension. With the device, the asymmetry was lowest at 60% of the threshold of the unaffected side. Conclusions: In this study, we developed an EMG-triggered FES device, and the pilot study result showed that the device reduces asymmetry.

Purpose: The purpose of this study is to analyze the deployment characteristics of korean and foreign mobile hospitals and to draw out the advantages and disadvantages based on the movement of patients. Methods: The arrangement and user movement lines of foreign mobile hospitals which were actually utilized, and the arrangements and user movement lines of korean mobile hospitals are compared and analyzed. Based on the results of the comparative analysis, we suggest the optimal placement of mobile hospital in Korea. Results: The recently developed Korean mobile hospitals have made many improvements. However, there is no practical use case for the mobile hospital in Korea, so it is necessary to establish the basis for the mobile hospital development site and the site access considerations. In addition, there is no detailed analysis of the movement of the administrators other than the medical staff, and it is considered that research on safe waste disposal is further needed. Implications: It is highly likely to be used as a basic data to find out the combination method of mobile hospitals that can efficiently deal with disasters through the arrangement and movement analysis of mobile hospitals in Korea and abroad.

The purpose of this paper is to understand and express emotions and experiences from the perspective of others through empathy, which is crucial for maintaining social relationships. The smooth formation of interpersonal relationships through the physical activity of children with disabilities holds significant meaning. Children with disabilities often lack opportunities for interaction with their peers compared to typical children, and the absence of effective communication methods poses difficulties in forming relationships. Therefore, this study aimed to investigate the effects of a movement education program on enhancing empathy in children with disabilities. The program was implemented for 12 weeks from April to June 2023, involving five children with disabilities. The movement education program comprised 12 topics, encompassing physical, emotional, and cognitive domains. Empathy was measured in two areas: cognitive empathy and emotional empathy. The results indicated improvement in both cognitive and emotional empathy after the program compared to the pre-assessment. The rate of progress varied depending on the type and severity of the disability, but overall, positive changes in the development of empathy were observed. Through this research, it is hoped that movement programs can be practically utilized as a valuable resource.

In order to research into the devel of the concept of movement and speed in our own way and compare with the Piaget's method, and then find out the formative period of such development, we have put the 192 primary school children as the model and obtained the following results. 1. As their grade upyards, all the experimental subjects showed the gradual progress generally regardless of sex or regions, while only the relative speed showed irregular progress. 2. There was no experimental subject which showed any remarkable sexual characteristics. But in the relative movement, the lower grade boys and higher grade girls made progress. In the subjects of circulation movement, intuition of speed, relative speed and speed of simultaneous movement, the boys marked better progress, whilst the girls were advanced a little in the speed of continuous movement with, different distance and time. 3. There was no conspicuous difference between the urban and rural areas, except a slight tendency that the urban children made better progress in the change of progressing direction, native continuous procedure of periodical movement, travelling road, and the speed of continuous movement with different distance and time whereas the rural children were more advanced in the relative movement, relative speed and intuition of speed. But it should be 'taken into consideration that the rural regions in our case were relatively developed in comparison with the traditional rural communities, which may explain about little regional difference. 4. Comparing our research results with the Piaget's theory, we have reached below results. Our research reports that the formative period of the conception of the problems of diverse progressing direction and a native continuous procedure of periodical movement was simultaneous, at the Piagetian level(at the fourth grade) which coincides with Piagetian theory. The travelling road should be made up a little lower at 2A/2B according' to Piagetian Level, whereas it was formed at the 4th grade as shown in our previous research. Intuition of speed should belong to the prior stage to concrete operation, but our research shows it was formed late at the 4th grade. Composition of displacement was made at the 6th grade, and it was almost equal to the first stage of formal operation(3A). But in the subjects of relative movement relative speed, the speed of continuous movement with different distance and time, relation and preservation of invariable speed, and accelerated motion, even 6th grade children marked a poor record. Summed up, the procedure conception as a basic movement conception coincides with the Piagetion level. But as for speed intuition, relative speed and speed fixation, it was Jar behind Piagetian level. Therefore it is required that we have to concentrate on the systematic training in these parts on the spot.

MARCH5 is a RING finger E3 ligase involved in mitochondrial integrity, cellular protein homeostasis, and the regulation of mitochondrial fusion and fission. To determine the function of MARCH5 during development, we assessed transcript expression in zebrafish embryos. We found that march5 transcripts were of maternal origin and evenly distributed at the 1-cell stage, except for the mid-blastula transition, with expression predominantly in the developing central nervous system at later stages of embryogenesis. Overexpression of march5 impaired convergent extension movement during gastrulation, resulting in reduced patterning along the dorsoventral axis and alterations in the ventral cell types. Overexpression and knockdown of march5 disrupted the organization of the developing telencephalon and diencephalon. Lastly, we found that the transcription of march5 was tightly regulated by the transcriptional regulators CHOP, C/EBPα, Staf, Znf143a, and Znf76. These results demonstrate the essential role of March5 in the development of zebrafish embryos.

Background: Research efforts to improve the pulmonary function of children with cerebral palsy (CP) need to focus on their decreased diaphragmatic ability compared to normal children. Real-time ultrasonography is appropriate for demonstrating diaphragmatic mechanisms. Objects: This study aimed to compare diaphragm movement, pulmonary function, and pulmonary strength between normal children and children with CP by using ultrasonography M-mode. The correlation between general characteristics, diaphragm movement, pulmonary function, and pulmonary strength was also studied. Methods: The subjects of this study were 25 normal and 25 CP children between five and 14 years of age. Diaphragm movement was measured using real-time ultrasonography during quiet and deep breathing. Pulmonary function (such as forced expiratory volume in one second; FEV1 and peak expiratory flow; PEF) and pulmonary strength (such as maximum inspiratory pressure; MIP and maximum expiratory pressure; MEP) were measured. A paired t-test and Spearman's Rho test, with a significance level of .05, were used for statistical analysis. Results: The between-group comparison revealed that normal children had significantly greater diaphragm movement, FEV1, PEF, MIP, and MEP (p<.05) than CP children. The results showed that general characteristics were significantly related to FEV1, PEF, MIP, and MEP (p<.05). Conclusion: In clinical settings, clinicians need to concern decreased diaphragm movement, pulmonary function, and pulmonary strength in CP group compared to normal children.

Objective : The purpose of this study was to analyze the effect of the elastic band on ballet arabesque based on kinematics analysis. Methods : To observe the effect of the elastic band, the availability of the elastic band during movement was set as the independent variable, and the dependent variables were set by using factors from two different categories such as motor mechanics and kinematics variables. For motor mechanics variable, the muscle activity and the center of pressure(COP)'s trajectory and velocity were used. Furthermore, the physical angle was used for kinematic variables. Data samples from the experiment was used to understand the correlation between independent and dependent variables while using paired samples t-test as a data analysis tool. Results : After analyzing the result of experiment, the usage of the Elastic band on ballet arabesque movement seemed to increase the activity of the agonistic muscle, which is mainly used for movement, and to improve the stability of the supporting leg by decreasing the trajectory and velocity of the center of pressure(COP). Moreover, the elastic band increased the level of elevation of the stretching leg with reducing the angle of the hip joint that resulted into a more stable movement and furthermore providing more beauty while standing on it. Conclusion : The movement training program while the using elastic band are expected to lead to appropriate muscular development and reduce the muscle imbalance, which usually occurs to dancers, during training with unfamiliar specific movements or strengthening muscular strength for a specific movement. In addition, this work is expected to be used as a training reference to understand and learn the fundamentals of movements of ballet and other dance fields.

In this paper, a regeneration inverter is proposed using 3-level inverter. Electric regeneration means regeneration brake in electric railway vehicles. Induction motors, generally used with railway vehicles, convert the electric energy to the movement energy when vehicle is running. When the vehicle stop, the induction motor convert the movement energy to the electric energy. Usually, this energy is used with another running vehicle in the same section. If there is no vehicle around when the regeneration is occurred, regeneration energy is consumed by heat energy with resistors. The proposed inverter is capable of reuse this regeneration energy in another place.
