PURPOSE: High-intensity physical therapy may help improve some gross motor developmental delays through an increased treatment frequency. This study describes an increase in physical therapy frequency and intensity over an eight-week time frame for a child with a rare genetic neurodevelopmental disorder. METHODS: A single-subject research was performed. The subject was a nine-year-old boy with MECP2 Duplication Syndrome. The outcome measure consisted of one time before and after the intervention. An intensive physical therapy program was applied to this subject. The treatments included reciprocal crawling, high kneeling, tailor sitting, weight-bearing and shifting training to facilitate ankle balance strategies and training to walk without assistance. RESULTS: After the eight-week follow-up, the child achieved a gradual improvement in the gross motor function measures, and the mother reported that the child frequently engaged in tailor sitting and independently walking. CONCLUSION: This case study highlights that intensive physical therapy improved the overall motor function of a child with MECP2 duplication syndrome.

The study aims to identify factors related to landscape structure and socioeconomic characteristics that influence adults' physical activity and health. The study analyzes data from 148,643 respondents from the Korea Community Health Survey conducted in 2021. The study measures various factors, including the frequency of physical activity, stress, depression, and landscape metrics of forest patches. Hierarchical multiple regression analysis was used, controlling for socio-demographic characteristics. Larger forest patches and more irregular shapes are associated with higher levels of physical activity among adults. The percentage and area of the forest patch are associated with fewer mental health complaints. Configuration-related landscape metrics such as shape or arrangement of the forest patch did not show a significant association with physical activity. Overall, the study provides insights into how specific characteristics of forest patches in urban areas may influence physical activity and mental health among adults. It emphasizes the importance of green spaces and their potential positive effects on both physical and mental well-being.

This study conducted a survey and investigated students' opinions and design preferences to physical education (PE) uniforms for elementary, middle and high school students using PE uniforms for the following purposes: to increase satisfaction with PE uniforms; present basic data for the development of PE uniforms helping to improve the quality of school life; and propose the development direction of PE uniforms. PE uniforms shall be developed with the components of uniforms, symbolism, functionality and aesthetics. The symbolism of PE uniforms expresses the affiliations of people wearing them and makes them have a sense of affiliation. The functionality presents convenience in students' physical activities and intramural/extracurricular activities. The aesthetics reflects the aesthetically sophisticated sport wear trend in PE uniforms. The development direction of PE uniforms was organized based on the result of analyzing and investigating students' opinions and design preferences to PE uniforms. There were differences in students' opinions and preferences to PE uniforms according to the type of student groups (elementary, middle and high school). In addition, there were clear gender-differences in the same student group. An effort might be required to reflect students' preferences because PE uniforms which students had currently worn at school had been manufactured without the reflection of students' opinions.

The purpose of this study was to realize and apply Taekwondo's technology and the fact that actors on stage and screen have much in common. In the meantime, there have been many prior studies on the development of the theoretical field. However, there is a slight lack of practical development and development plans, and it is time to improve. This seems to be a lack of practical experience leading to the creation of physical images. In that sense, I think that it should be supported by the complement of concrete and detailed research that seeks to make changes in open technology significantly. Considering this situation, it is necessary to further develop the practical field in parallel with the theoretical field. Therefore, I suggested the principle of physical behavior through Taekwondo technology and the development of acting skill. The performance training using these taekwondo techniques is meaningful research.

Small intestine has a structure called villi that increases the mucosal surface area for nutrient absorption. Intricate and tight epithelial-mesenchymal interactions are required for villi development. These interactions are regulated by signaling molecules, physical forces, and epithelial deformation. Signaling molecules include hedgehog (Hh), bone morphogenetic protein (BMP) and Wnt ligands. The Hh ligand is expressed from the epithelium and binds to the underlying mesenchymal cells, resulting in aggregation into mesenchymal clusters. The clusters express BMP and Wnt ligands to control its size and spacing between clusters. The clusters then form villi. Despite the fact that the villi formation is studied extensively, we do not have a complete understanding. In addition, the recent study shows there is a great relationship between the overexpression of the Hh signal and development of cancer in the gastrointestinal tract. Therefore, signaling between epithelial and mesenchymal cells and their physical interactions will be discussed on this review.

Economic development is usually identified with the increased of G.N.P and capital formation connected directly wi:11 the net increase of land, structure, commodity, stocks and foreign claims, etc. The increase of G.N.P. is driving at capital formation. The usual concept of capital formation for economic development misses the important productivity factor of human capital. Because it is now increasingly realized that a massive injection of material into production will 11 not necessarily explain a successful productivity unless that country already possesses 1 suitable human capital. Human capital is built of educational investment which is related to the physical capital. Many statistical investigations identified this reality. Of late years, a great crowd of economists studying an the problem of economic development have turned their attention towards human capital. Thereupon, this paper has dealt with the fact that educational investment affects physical capital and employment. The qualitative increment of human capital will increase the productivity but excessive expenditure on human capital will squander a physical capital. In designing a strategy of human capital for economic development, one needs to consider tile level of educational investment because educational investment of developing countries will be accasionaly made or marred by investment level and direction.

Purpose: Designed to examine the effects of aerobic exercise therapy on elders' physical functions. Methods: Selected from an elderly welfare center in an agricultural district located in N City. Thirty seven elders were selected in the experimental group and 38 in the control group, and all the subjects aged over 65. Collected data were statistically analyzed by SPSS/PC 12.0 Win. Detailed data analysis methods were Chi-square, Fisher's exact test, Kolmogorov-Smirnov test, t-test, Mann-Whitney u-test, paired t-test, and Wilcoxon's rank sum test. Results: The first hypothesis "The experimental group who had the aerobic exercise therapy will have greater development in lower leg muscular strength compared to the control group" was supported (t=8.95, p<.001). The second hypothesis "Aerobic exercise therapy participants will show greater development in lower leg endurance" was supported (t=6.12, p<.001). The third hypothesis "Aerobic exercise therapy participants will show greater development in flexibility" was supported (U=49.00, p<.001). The forth hypothesis "Aerobic exercise therapy participants will show greater development in balance" was supported (U=322.00, p<.001). Conclusion: The aerobic exercise therapy showed positive effects on physical functions of the elderly in a rural area.

In polymer precursor based activated carbon, the structure of starting material is likely to have profound effect on the surface properties of end product. To investigate this aspect phenolic resins of different types were prepared using phenol, mcresol and formaldehyde as reactants and $Et_3N$ and $NH_4OH$ as catalyst. Out of these resins two resol resins PFR1 and CFR1 (prepared in excess of formaldehyde using $Et_3N$ as catalyst in the basic pH range) were used as raw materials for the preparation of activated carbons by both chemical and physical activation methods. In chemical activation process both the resins gave activated carbons with high surface areas i.e. 2384 and 2895 $m^2/g$, but pore size distribution in PFR1 resin calculated from Horvath-Kawazoe method, contributes mainly in micropore range i.e. 84.1~88.7 volume percent of pores was covered by micropores. Whereas CFR1 resin when activated with KOH for 2h time, a considerable amount (32.8%) of mesopores was introduced in activated carbon prepared. Physical activation with $CO_2$ leads to the formation of activated carbon with a wide range of surface area (503~1119 $m^2/g$) with both of these resins. The maximum pore volume percentage was obtained in 3-20 ${\AA}$ region by physical activation method.

A simple but effective method has been developed for estimating diurnal and semi-diurnal tidal currents from trajectories of satellite-tracked drifters. The estimation method consists of separation of tidal current signals contained in the drifter trajectories, computation of undulations by diurnal and semi-diurnal currents, and correction of dominant diurnal and semi-diurnal tidal constituents. M$_2$ tidal currents estimated from drifter trajectories in the Yellow Sea are well consistent with those observed by moored current meters and this supports the validity of this method. We have constructed M$_2$ tidal current chart in the Yellow Sea by applying this method to available drifter trajectories collected during 1994-1998. According to this chart, M$_2$ current in the Yellow Sea rotates in the clockwise direction south of 35$^{\circ}$ 30'N but in the counterclockwise one to the north. Also it is found that the M$_2$ current is strong in the bank area northeast of the Changjiang River mouth and in the Korean coastal area, while it is weak in the deep central trough.
