By referring to relevant literature, we will deeply study the development of school sports in the early Republic of China, the rise of the New Culture Movement, the advocates and advocates of new culture, actively promote "new sports", and strive to overthrow the dregs of military nationalism education ideas and change the impact of Japanese gymnastics on school sports. With the outbreak of the "May Fourth Movement", the New Culture Movement not only had a greater impact on education and culture, but also accelerated the domestic political game to a certain extent, which ultimately led to the transformation of school physical education and the realization of Pragmatism education. In view of this, this article will start from an overview of the characteristics of school sports in the early Republic of China, focus on the analysis of the impact of the May Fourth New Culture Movement on the transformation of school sports in the early Republic of China, and then explore the incentives for the transformation of school sports under the May Fourth New Culture Movement, hoping to play a certain reference role.

Buru Regency is the primary hub for producing eucalyptus oil, a highly valued commodity in the region. The oil extracted from the eucalyptus epidemic plant possesses antiseptic, antibacterial, and antifungal characteristics. Amidst the Covid-19 pandemic, numerous industries require it as a fundamental component of pharmaceuticals. An essential factor in the eucalyptus oil production process is the presence of eucalyptus leaves. Therefore, leaf-sorting workers, including women, are required to ensure this availability. However, in reality, the daily lives of eucalyptus leaf massagers are characterized by challenging economic conditions and a socio-economic environment that lags behind workers in other sectors. This study aims to examine and investigate the roles and work patterns of employed women and the strategies they employ to ensure the consistent flow of household income. The research employed a qualitative methodology with a phenomenological approach. A total of 24 informants were purposefully selected based on their involvement in achieving the research objectives. The results indicate that the COVID-19 pandemic has altered the circumstances of women who collect leaves and rely heavily on eucalyptus trees as a natural resource. Physical adaptation strategies are the preferred methods used to fulfill household requirements. Implementing physical adaptations does not deter women leaf-sorters from continuing their work. Their commitment to meeting their basic needs significantly motivates them to persist in their role as leaf sorters. The income of women engaged in sorting eucalyptus leaves in their households during the COVID-19 pandemic.

With the increasing climate change crisis, the ongoing global energy security challenges, and the prerequisites for the development of sustainable and affordable energy for all, the need for renewable energy resources has been highlighted as a global aim of mankind. However, the worldwide deployment of renewable energy calls for large-scale financial and technological contributions which many States cannot afford. This exacerbates the need for the promotion of foreign investments in this sector, and protecting them against various threats. International Investment Agreements (IIAs) offer several substantive protections that equally serve foreign investments in this sector. Fair and Equitable Treatment (FET) clauses are among these. This is a flexible standard of treatment whose boundaries are not clearly defined so far. Investment tribunals have diverse views of this standard. Against this background, this article asks: What are the prominent international renewable energy investment threats, and how can FET clauses better contribute to alleviating these concerns? Employing a qualitative method, it analyses the legal aspects and properties of FET and concludes that the growing security and regulatory threats have formed a sort of modern legitimate expectations on the part of renewable energy investors who expect host states to protect them against such threats. Hence, IIAs and tribunals need to uphold a definite and broadly applicable FET approach to bring more consistency and predictability to arbitral awards. This would help deter many unfavourable practices against investments in this sector.

This paper investigates and studies the quality of life of primary school students, and the results show that the quality of life of primary school students in Chongchuan District of Nantong is generally at the upper middle level, and it shows a downward trend with age. There were significant differences between 8-year-old boys and girls in “teacher-student relationship”, “learning ability and attitude”, “self-concept relationship”, “peer relationship” and “homework attitude”, and girls were better than boys. There were significant differences between 10-year-old boys and girls in the scores of “teacher-student relationship” and “self-satisfaction relationship”, and girls were better than boys; There were significant differences between 11-year-old boys and girls in the two factors of “activity opportunity” and “athletic ability”, and boys were better than girls. There was no difference in the remaining ages by factor. Improving the quality of life of primary school students requires the active cooperation of schools, teachers and parents, as well as special attention to the differences between boys and girls aged 8, 10 and 11.
