New insights into the aetiology of anaemia in athletes have been discovered in recent years. From hemodilution and redistribution, which are thought to commit to so-called "sports anaemia," to iron deficiency triggered by higher requirements, dietary requirements, decreased uptake, enhanced losses, hemolysis, and sequester, to genetic factors of different types of anaemia (some related to sport), anaemia in athletes necessitates a careful and multisystem methodology. Dietary factors that hinder iron absorption and enhance iron bioavailability (e.g., phytate, polyphenols) should be considered. Celiac disease, which is more common in female athletes, may be the consequence of an iron deficiency anaemia that is unidentified. Sweating, hematuria, gastrointestinal bleeding, inflammation, and intravascular and extravascular hemolysis are all ways iron is lost during strength training. In training, evaluating the iron status, particularly in athletes at risk of iron deficiency, may work on improving iron balance and possibly effectiveness. Iron status is influenced by a healthy gut microbiome. To eliminate hemolysis, athletes at risk of iron deficiency should engage in non-weight-bearing, low-intensity sporting activities.

Although the history of the game of Go is more than 2,500 years, the theoretical studies of Go are still insufficient. In recent years a lot of studies using Artificial Intelligent(AI) have been conducted, but they do not provide the prominent theoretical reality. We applied Principal Component Analysis(PCA) to the professional Go openings, which are the early stage in Go, to analyze them especially focused on the Go game records of the professional 9-dan player Lee Sedol who is the world's top professional Go player. The results showed that among the 361 eigenvectors the 48 most significant eigenvectors capture most of the variance (99.9%) and the 30 most significant eigenvectors enable to possess 90.5 percent of the total variance. This result would be expected to considerably contribute to pattern recognition research of the professional Go openings in the near future.

Korea professional baseball industry has grown to take the lion's share of the domestic sports industry, but still does not make break even. The purpose of this study is to examine the financial impact of adopting the Customer Relation Management (CRM) approach on the profitability of Korea professional baseball industry. We use a measuring tool called entropy used in ID3 decision tree algorithm. In the paper, we specify five the most important factors that affect spectator satisfaction based on the previous literature, perform survey analysis, calculate entropy values, and find the results. We predicted the change in revenues when we adopt CRM by checking the spectators' willingness to pay more when the conditions of each factor are improved. We find that we can reap significant fruits of the effect of CRM introduction through enhancing 'game content factor' and 'game promotion factor' among the five factors. We also find that we can increase the revenues of domestic professional baseball teams to 2.4 times or 2.1 times the current level if we manage intensively those two factors respectively. It is very surprising to see that the improvement in total revenues makes both ends meet for domestic professional baseball teams. This clearly demonstrates the effectiveness of CRM approach in improving the profitability of organizations.

Educational reform in Ukraine encourages the use of multimedia technologies in the training of specialists in Physical Education and Sports, which is one of the promising directions of education development. Therefore, the article specifies the content of the terms "innovation" and "technology". For modern society, the introduction of multimedia technologies in education is not so much theoretical as pragmatic, since under condition of globalization it concerns its historical development and prospects associated with the so-called "high technologies".Our goal is to improve the training of Physical Education and Sports specialists by means of multimedia technologies. All of innovative technologies can be divided into four groups, depending on the appropriate form of educational activity for their use. The development of multimedia technologies in the training of specialists in Physical Education and Sport at the present stage of education development should be carried out in accordance with the criteria of manufacturability, which are presented in the article: scientism, to rely on the theoretical provisions of pedagogical science and methods of teaching the discipline, socially recognized educational goals, prospects for modernization of Education; consistency, which provides for the interaction of parts and the whole in the organization of the study environment, as a result of which the physical development of the young generation is an integral entity; guarantee, that is, the error between the planned and obtained results should be minimal; manageability, that is, full management of the stages of work of the teacher and students, which make up the completed cycle of actions; mass participation, for the purpose of applying the technology does not depend on the physical training of students, the pedagogical skill of the teacher and the type of educational institutions. The article presents the theory and method of organizing sports events and circuses in the training of specialists in Physical Education and Sports by means of multimedia technologies. In order to increase the level of physical development of a person, physical fitness and the state of health of students, which has a clear trend to constant deterioration, it is necessary to instill love for sports, carry out high-quality training and organize sports events using multimedia technologies. In the process of sports activities, the participants' mental education is carried out. There are two types of communication here: direct and indirect, which are described in the article.In games and sports competitions, there are many opportunities for forming rules of collective behavior. The main issues of the organization of sports activities by means of multimedia technologies have been clarified. During sports competitions, the tasks presented in Physical Education and sports classes are improved, which ensure the improvement of physical and theoretical training of the individual. The pleasure of sports, bright, emotional spectacles, confirmed by multimedia technologies, arises from the participation of the viewer in them.

The purpose of this study is to improve the academy sports field for the establishment of advanced sports culture. This study used qualitative research. The research participants were baseball players for 11 years and have been professional baseball players. Another study participant has been a soccer player for eight years. And he has been a football coach for 13 years. The results of this study are as follows. First, the act of entertaining was the form in which parents served sports leaders meals and alcohol. Parents' student athletes had increased chances of playing in the game and were able to receive faithful guidance. Second, the student athletes whose parents did not act of entertaining to the sports leader were discriminated against. The student athletes were harassed by their leaders, their positions changed, and their chances of playing were reduced. Third, parents' student athletes who did not act of entertaining to their leaders either stopped exercising or moved to another school because of discrimination. Eventually, the entertainment culture of academy sports acted as a mechanism to induce sports de-socialization of student athletes, and made students experience a negative aspect of sports culture. As a result, the entertainment culture of academy sports caused discriminatory treatment due to economic inequality. Therefore, the negative entertainment culture of academy sports should be eradicated for the establishment of advanced sports culture.

Functional inner-wear being currently sold is being made without regard to the characteristics of various sports events. The purpose of this study is to identify this problem and to investigate the effect of sports taping on golf swing when wearing functional inner-wear. The subjects of this study were 8 male golfers belonging to Korea Professional Golf Association, and Launch monitor and Trackman were used to find out golf club action, ball pitch, distance, etc. There are three types of clubs: driver, wood, and iron, and the first experiment was carried out using only functional inner-wear. In the second experiment, we experimented with functional inner-wear after sports taping, and we compared and analyzed the distance depending on each experiment, the speed of the ball and the club, and the accuracy of the club face. The results of the study were as follows. As a result of driving distance, according to the presence of sports taping on functional inner-wear, there was a statistically significant difference in the driving swing and wood swing, for club and ball speed, there was a statistically significant difference only in the driving swing. Regarding the accuracy by the presence of sports taping on inner-wear, there was a statistically significant difference in the driving swing, wood swing, and iron swing. In conclusion, the sports taping in the functional inner-wear had a positive effect on golf performance improvement, and we hope that golf inner-wear these two specifications combing will be developed in the future.

It is expected to continue to increase the number of people who enjoy marine and water sports due to the increase of leisure time because of income increase, the five-day workweek, etc. However, in the safety awareness, the development of equipment is just in the early stage. Established system for fundraising is required for Korean marine and water sports to be developed first. Should the fund be spent on the safety and development of domestic equipment for marine and water sports, it would make for a safer and more enjoyable sports for the people. The profit return measures of motor boat race, among marine and water sports, are surveyed and analyzed to suggest the measures stated above. Japanese legal structure and the profit return measures on motor boat race, which are about 60 years ahead than Korean systems, were analyzed and led to suggest the establishment of professional institutions which promote motor boat, etc. and the legal improvement for funding.

We studied the relations between variables related to fan's preference in a area of pro-baseball which is the most popular one among pro-sports. The dependent variables are pro-baseball team fan's preference to both the team and the products of the company which has a pro-baseball team, while the independent variables are sex, age, and hometown of fans. Eight hypotheses are constructed with those variables. For testing them a questionnaire was used, whose reliability was checked using Kronbach Alpha. Subjects were 314 college students in a local city. For statistical analysis nonparametric tests like Mann Whitney test, Kruskal-Wallis test, etc were used. Useful and significant results among variables were obtained. Since these results have important implications about management of pro-sports teams and fans and fans Preference to products in a view of sports marketing management, more researches should be done continuously in the future in this area.

Currently, the sports market continues to grow every year, and among them, professional baseball's entry income is larger than the rest of the professional league. In sports, strategies are used differently in different situations, and the analysis is based on data to decide which direction to implement. There is a part that a person misses in an analysis, and there is a possibility of a false analysis by subjective judgment. So, if this data analysis is done through artificial intelligence, the objective analysis is possible, and the strategy can be more rationalized, which helps to win the game. The most popular baseball to be applied to artificial intelligence to analyze athletes' strengths and weaknesses and then efficiently establish strategies to ease the competition. The data applied to the experiment were provided on the KBO official website, and the algorithms for forecasting applied linear regression. The results showed that the accuracy was 87%, and the standard error was ±5. Although the results of the experiment were not enough data, it would be possible to effectively use baseball strategies and predict the results of the game if the amount of data and regular data can be applied in the future.
