  • 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.

  • The purpose of this study is to examine the functionality with improved pattern-design working uniform(protocol, P) and current working uniform(control, C). Movement functionality evaluation of improved pattern-design working uniform was carried out through sensory evaluation of working uniform. Movements for the sensory evaluation consisted of four types of up and down and horizontal movements of the shoulders, four types of waist movements and five types of knee movements. The results have been shown as follows: The sensory value of back girth, wrist, side seam area of the "P" with the posture of raising an arm forward up to $90^{\circ}$ and the maximal arm's vertical movement significantly improved compared to the "C". Therefore, it can be concluded that movement functionality was increased with the improved pattern-design working uniform in the respect of arm's up and down movement. Furthermore, for P, Movement functionality improvements were shown in P with arm's horizontal movement, waist bending movement, and knee movement. Current working uniform(C) is jumper-type which wa designed without consideration for movement functionality of the arms and legs. But Pattern-design uniform(P) which was developed in this study. Therefore, the more patterns development, the better movement functionality in working uniform. The improved movement functionality improvements in working uniform will provide not only personal pleasantness but also efficiency of productivity at construction sites. In respect of human body's movement, further study for improved working uniform is required.

  • Plasmodesmata (PDs) are specialized intercellular channels that facilitate the exchange of various molecules, including sugars, ribonucleoprotein complexes, transcription factors, and mRNA. Their diameters, estimated to be 2.5 nm in the neck region, are too small to transfer viruses or viral genomes. Tobacco mosaic virus and Potexviruses are the most extensively studied viruses. In viruses, the movement protein (MP) is responsible for the PD gating that allows the intercellular movement of viral genomes. Various host factors interact with MP to regulate complicated mechanisms related to PD gating. Virus replication and assembly occur in viral replication complex (VRC) with membrane association, especially in the endoplasmic reticulum. VRC have a highly organized structure and are highly regulated by interactions among the various host factors, proteins encoded by the viral genome, and the viral genome. Virus trafficking requires host machineries, such as the cytoskeleton and the secretory systems. MP facilitates the virus replication and movement process. Despite the current level of understanding of virus movement, there are still many unknown and complex interactions between virus replication and virus movement. While numerous studies have been conducted to understand plant viruses with regards to cell-to-cell movement and replication, there are still many knowledge gaps. To study these interactions, adequate research tools must be used such as molecular, and biochemical techniques. Without such tools, virologists will not be able to gain an accurate or detailed understanding of the virus infection process.

  • This study was performed to investigate the effect of change of body posture on the rest position and the rotational torque movement of the mandible. Thirty dental students without any signs and symptoms of temporomandibular disorders and with natural dentition were selected for this study. Cervical inclination and the amount of the mandibular movement on protrusion, on left and right excursion, and on tapping in three body postures such as sitting position, supine position without pillow, and supine position with pillow were measured by goniometer, Cervical-Range-of-$Motion^{(R)}$, and mandibular tracking device, $BioEGN^{(R)}$ with $Rotate!^{(R)}$ program. The data obtained were classified and processed according to body posture and type of lateral guidance with SPSS windows program and the results were as follows: 1. There was significant difference among the three cervical inclinations by body postures. 2. Comparison of mandibular rest positions among body postures showed significant difference only for lateral distance in frontal plane, but comparison between before and after swallowing showed significant difference except for the lateral distance, vice versa. 3. Distance and amount of the rotational torque movement on protrusion and/or lateral excursions didn't show any difference by body posture. But by both body posture and lateral guidance type, there were slightly significant difference for some items. 4. A significant difference was shown for the rotational torque movement in frontal plane on tapping by body postures, for the lateral distance in frontal plane on sitting position by lateral guidance type, and for the rotational torque movement in frontal plane by both body posture and lateral guidance type.

  • This study develops a coverall design for the body shape and movement of infants. This research analyzed these processes: 1. The current coverall styles preferred for infants. 2. The appropriate products for the real size, body shape, movement, and fit of infants. 3. The observations of the 6 months to 9 months movement and development of infants. 4. The design and creation of a new coverall base in this study, and to check the suitable test the developed coverall design for the infant. The result of this study are: A coverall for infants that lie or crawl on the floor must avoid opening in the center front and a gore has to be added at the crotch of the pants for the better movement of infants. These ways provide infants a neat appearance and easy movement. The test of developed designs shows that the developed coverall design covers the size gap of the trunk loop according to the growth of the infant and the movement of the legs; in addition it provides a positive aesthetic effect. The waistline in the developed coverall (a waistline that should exist lower than the body waistline of the infant) can reduce seam stress because the pressure of the seam line can be absorbed in a dipper. It is one of the suitable design points for infants lying prone all day long in this study.

  • This study explores the background and the processes underpinning the educational reform movement based on local community. This educational community initiated the alternative education reform movement, which is referred to as the small school movement. A qualitative case study was implemented by collecting data from thirty articles, three focused interviews. This study drew out three key factors as the operation of educational community in regional area. First, it claimed a total of 30 papers related to the educational community for content analysis. Second, key words were derived in the local educational community context. They developed their own alternative educational programs, such as self-supportive meeting, season carnivals, community revitalization activities, and so on. Their focus was on finding out and establishing better educational relationships among the concerned communities. Third, the community continues to reinforce the internal rules and climate through meta-education, a process, in which education educates itself. As a result, they could enjoy substantial success in a visible educational community. This small school revival movement later grew into the new school movement. Furthermore, a variety of teachers, parents groups, and interested scholars have been engaged in the community movement through professional networking. This study suggests that the key innovator-initiated movement, which involves education reform, upgraded Korean education, and improved their own expertise and autonomy, is expected to be the first step to solve the current Korean educational problems by the educational community.

  • Purpose : The purpose of this research is to propose a more efficient exercising method by measuring and comparing the movement of center of pressure (COP) while hemiplegic stroke patients perform kneeling squat exercise and squat exercise. Methods : 17 hemiplegic stroke patients were instructed to perform kneeling squat exercises and squat exercises, and the research was designed as a cross-over study. For data collection, a pressure distribution measurement platform (PDM) was used to measure the movement area, length, speed, and distance from the center of the X-axis of center of pressure. The data was then analyzed through a paired t-test. Results : Kneeling squat exercises have been found to have a significantly smaller center of pressure movement area compared to that of squat exercise(p<.001), and the center of pressure movement length of kneeing squat exercise has also been found to be relatively shorter (p<.001). Moreover, kneeling squat exercises have been found to have a significantly slower center of pressure movement speed than squat exercise (p<.001), and kneeing squat exercise center of pressure movement distance from the center of the X-axis has been found to be significantly small (p<.001). Conclusion : Kneeling squat exercises have significantly decreased amounts of center of pressure movement area, distance, and speed compared to squat exercises. Also, the center of pressure movement distance from the center of the X-axis was relatively closer. This result seems to derive from patients performing their motions with wide base surfaces while being refrained from using unstable ankle joints during kneeing squat exercise. Therefore, it can be concluded that kneeing squat exercises show relatively balanced center of pressure movements between the paralyzed and non-paralyzed sides because kneeling squats show smaller shakes in the center of pressure.
