Tennis, as an important project of sports, has an obvious role in cultivating students' physical quality, observation ability and reaction speed. Under the background that the country attaches great importance to students' physical literacy, the traditional single and passive teaching has been unable to meet the practical needs, so it is necessary to strengthen the innovation of teaching methods. With the recognition of many teachers, the teaching method of "combining competition and practice" has been continuously promoted. The paper takes the combination of competition and practice as the teaching mode, and studies the teaching of college tennis sports.

Children have an innate curiosity and desire to explore. Curiosity, easy to ask, good exploration is the age characteristics of children, inquiry is not only the goal of children's scientific learning, but also the way of children's scientific learning. Phenomenon of nature and the real things in life and also children explore the vivid content in the mixed age club, so when mixed age club activities from the Angle of view of the child, with various kinds of way to carry out exploratory area activities, around the child's interest, with the advanced type questions as clues of mixed age club inquiry activity, inspire children's bold, independent to participate in class activities, Really become a small host of activities.

The purpose of this study is to explore the client service experience of medicaid case managers in Korea and prepare health protection measures. The research method was in-depth interviews, and data was collected twice in total from 04 September to 06 September, 2023. The study participants were five medicaid care managers belonging to cities, counties, and districts across the country. As a result of this study, participants experienced problem behaviors such as unreasonable demands, verbal abuse and assault, a threatening environment, a passive attitude toward expressing emotions, and a defensive attitude when performing work. In addition, the participants appeared to be unaware of the organization’s management policy, the absence of a healing program for health disorders, and the follow-up management system to resolve client problem behavior. In conclusion, the organization must establish a safety and health management policy, establish a grievance handling committee, conduct safety and health education, investigate job stress and prepare countermeasures, prepare follow-up measures to protect health, and prepare a job stress relief program.

This study seeks to explore the information value of financial metrics on corporate sustainability and investigate the moderating effects of institutional shareholders on the association between net cashflows (NCF) and corporate sustainability of the leading ASEAN countries. The dataset consists of companies listed on the Stock Exchange of Thailand, Malaysia and Singapore during 2013–2023. Fixed effects panel regression is executed in this study. Subsequently, the conditional effects served to evaluate the influence of institutional shareholders on the association between NCF and corporate sustainability. This study employs agency theory to explore how the alignment of institutional shareholders influences sustainability outcomes. This study found that institutional shareholders themselves supply information for the sustainability indicator in Thailand and Singapore, but not in Malaysia. Furthermore, adversely correlated with sustainability metrics in all three nations is the interaction term between institutional shareholders and net cashflows. Further investigation reveals that for each nation’s sustainability measures the institutional shareholders offer value relevant to net cashflows at certain amounts. This study not only contributes to existing academic research on sustainability and financial indicators, it also provides practical strategies for companies and investors trying to match financial performance with sustainability goals in a fast-changing global market.

Recognizing the importance of competition analysis in telecommunications markets is essential to improve conditions for users and companies. Several indices in the literature assess competition in these markets, mainly through company concentration. Artificial Intelligence (AI) emerges as an effective solution to process large volumes of data and manually detect patterns that are difficult to identify. This article presents an AI model based on the LINDA indicator to predict whether oligopolies exist. The objective is to offer a valuable tool for analysts and professionals in the sector. The model uses the traffic produced, the reported revenues, and the number of users as input variables. As output parameters of the model, the LINDA index is obtained according to the information reported by the operators, the prediction using Long-Short Term Memory (LSTM) for the input variables, and finally, the prediction of the LINDA index according to the prediction obtained by the LSTM model. The obtained Mean Absolute Percentage Error (MAPE) levels indicate that the proposed strategy can be an effective tool for forecasting the dynamic fluctuations of the communications market.
