What sports have in common is that they must use their bodies to play and lead to victory. The use of the body differs in many ways depending on the event, which part should be used as the focus. The commonality of all sports is that sports can achieve the best results by using and using parts of the body in harmony. The use of strength or muscles varies depending on the type of sport or the type of sport, so the use of the body or the results of athletic events also varies. Sports are premised on the organic use of the body, but the implications of sports can be found in that the degree of organic use does not apply equally to all sports. Sports demand organic balance and flexibility. Depending on the type of sport, you can explore which organic harmony produces more effective effects and find out which events are more beneficial to the human body. This study aimed to find out whether the organic harmony of the body actively contributes to the development of sports and a healthy mental culture. In this study, we proposed the hypothesis that the modern Pentathlon will induce the most desirable organic harmony as a global Olympic sport, and tried to verify that the hypothesis is valid and verifiable. In order to do this study, I tried to find out the organic viewpoints centered on the Miletos school, re-examine the meaning of the modern Pentathlon of games as an Olympic event, and conduct organic harmony and exploration of the modern Pentathlon of games in terms of sports.

This paper improves the possibility of recognizing fast-moving objects through the YOLO (You Only Look Once) deep learning recognition model in an application environment for object recognition in images. The purpose was to study the method of collecting semantic data through processing. In the recognition model, the moving object recognition error was identified as unrecognized because of the difference between the frame rate of the camera and the moving speed of the object and a misrecognition due to the existence of a similar object in an environment adjacent to the object. To minimize the recognition errors by compensating for errors, such as unrecognized and misrecognized objects through the proposed data collection method, and applying vision processing technology for the causes of errors that may occur in images acquired for sports (tennis games) that can represent real similar environments. The effectiveness of effective secondary data collection was improved by research on methods and processing structures. Therefore, by applying the data collection method proposed in this study, ordinary people can collect and manage data to improve their health and athletic performance in the sports and health industry through the simple shooting of a smart-phone camera.

The purpose of this study was to improve upon school health by understanding the present status of school health and escpecially to investigate the performance rate of regular health instruction. 261 schools, including middle and high schools enrolled in the Busan Educational Association, were sent Questionnaires. Data was collected from the 25th of January to the 10th of April, 1994. 229 subjects who responded to the Questionnaires were finally analyzed as samples. Among them, 127 were school nurses and 102 were teachers acting in a school health capacity. The results of this study are summerized as follows: Of the teachers holding additional school health responsibilities, $85.6\%$ worked in private schools. Many of them $(74.5\%)$ were formally dissatisfied with their ability to provide care because $85.3\%$ of them had never studied any school health. Some of them$(30.4\%)$ didn't know about the annual school nursing budget and $23.5\%$ of them hadn't taught any health education to students. In spite of this fact, they were placed in charge of a school health activity against their own will. There were statistically significant differences in the performance of school health affairs between nurses and teachers holding additional school health (p<0.001) as follows: annual school nursing budget, Health Program Planning and Evaluation, annual purchase price for medicines, average students cared for per day, average students who held at least one consultation per month and extra. Surely, the self-confidence of school nurses was higher than that of teachers with school health as an assigned responsibility. This was demonstrated by a significant statistical difference (p<0.01) in the responses by the two groups. $88.2\%$ of the school nurses and $73.5\%$ of teachers for school health thought that regular health instruction was necessary. But regular health education had been performed only by $32.8\%$ of respondents. Among them, 84% were school nurses and $16\%$ were teachers holding additional school health. Of the persons who performed regular health education, $69.3\%$ used less than $60\%$ of the health content of the athletic textbook. And $64\%$ of them said teaching materials were insufficient. Most of them $(69.4\%)$used home made lesson plans. which they compiled from various sources. There was a significant difference in the formality of the health lesson according to the concern of the school principal (p<0.01) and there was a significant difference in performing health education between school nurses and teachers holding additional school health (p<0.001) It appears that there are a lot of problems with providing school health care using people who are untrained. In a word, school health nurses with professional training are needed in order to perform the qualitative management for the health of the students. These days, regular health education is an indispensable part in making students improve their self-care abilities. Therefore a more effective and better defined program should be prepared for regular systematic health education. To resolve these problems, present laws and regulations related to school health should be revised considering the specialist's request for the improvement of school health. In addition, the concern and financial support of the government are essential.

Introduction: Sleep has numerous important physiological and cognitive functions that may be particularly important to elite athletes. Sleep deprivation can have significant effects on athletic performance. However, there are few published data related to the amount of sleep obtained by elite athletes. We investigated sleep patterns of Korean women golfers using sleep-related questionnaires. Methods: For this study, 98 Korean university women golfers and 46 age- and sex-matched controls were recruited. All subjects were asked to complete the self-administered sleep questionnaire consisting of questions about habitual sleep patterns (sleep onset time, sleep latency, awakening time in the morning, day time napping time), exercise habits, Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISS), Pittsburgh Sleep Quality Index (PSQI), validation of the Perceived Stress Scale (PSS), and Beck Anxiety Inventory (BAI). Results: The sleep onset time was significantly earlier (pm 23 : $05{\pm}00$ : 52 and 00 : $14{\pm}00$ : 51 ; t = 5.287, p < 0.001), the waking time was later (am 07 : $21{\pm}01$ : 09 and 6 : $35{\pm}00$ : 32; t = -2.715, p = 0.008), the weekday total sleep time was greater ($417.77{\pm}78.18$ minute and $351.52{\pm}77.83$ minute ; t = 4.406, p = 0.001), and the daytime nap time was greater ($77.73{\pm}41.28$ minute and $20.22{\pm}33.03$ minute ; t = 7.623, p < 0.001) in the golf athletes compared to the controls. The PSQI scores were significantly lower, but estimated sleep latency and ESS, ISS, PSS, and BAI scores were not different among the two groups. Conclusion: This study suggests that Korean university women golfers have good sleep patterns resulting in no difference in sleep-related stress compared to age- and sex-matched control students.

The purpose of this study was to characterize equine heat-shock protein (Hsp) genes and analyze their expression pattern in various horse tissues and blood leukocytes after exercise. In a previous study, RNA sequencing of blood and skeletal muscles of thoroughbreds before and after exercise was performed using differently expressed gene (DEG) analysis. Three Hsp genes (HspH1, Hsp90${\alpha}$ and Hsp70) were selected by DEG analysis and were found to be differentially expressed in either blood or muscle. To validate and extend previous observations on these genes, we performed RT-PCR analyses of horse tissue as well as real-time qPCR analyses of blood leukocytes after exercise. mRNA expression of these Hsp genes was found to be ubiquitous in the analyzed tissues (including thyroid, colon, skeletal muscle, cecum, kidney, spinal cord, heart, and lung). In addition, Hsp mRNA expression of these genes in extracted whole blood increased after 120 minutes of exercise compared to the baseline condition. These results are in agreement with the results of human and other experimental animals, suggesting that regulatory mechanisms that are responsible for upregulation of Hsp gene transcription may be conserved among species. Further investigations to correlate Hsp gene expression patterns with athletic performance or recovery processes after exercise are warranted.

Athletic performance is an important criteria used for the selection of superior horses. However, little is known about exercise-related epigenetic processes in the horse. DNA methylation is a key mechanism for regulating gene expression in response to environmental changes. We carried out comparative genomic analysis of genome-wide DNA methylation profiles in the blood samples of two different thoroughbred horses before and after exercise by methylated-DNA immunoprecipitation sequencing (MeDIP-Seq). Differentially methylated regions (DMRs) in the pre-and post-exercise blood samples of superior and inferior horses were identified. Exercise altered the methylation patterns. After 30 min of exercise, 596 genes were hypomethy-lated and 715 genes were hypermethylated in the superior horse, whereas in the inferior horse, 868 genes were hypomethylated and 794 genes were hypermethylated. These genes were analyzed based on gene ontology (GO) annotations and the exercise-related pathway patterns in the two horses were compared. After exercise, gene regions related to cell division and adhesion were hypermethylated in the superior horse, whereas regions related to cell signaling and transport were hypermethylated in the inferior horse. Analysis of the distribution of methylated CpG islands confirmed the hypomethylation in the gene-body methylation regions after exercise. The methylation patterns of transposable elements also changed after exercise. Long interspersed nuclear elements (LINEs) showed abundance of DMRs. Collectively, our results serve as a basis to study exercise-based reprogramming of epigenetic traits.
