China’s rapid development in modern times has become an important country in the world. Therefore, the cultures of various countries continue to cross and integrate in China. Language is the carrier of culture. Under the function of language, international culture is constantly spread and exchanged. As an important part of basic education, language education, especially college English education, significantly contains multiple international cultures. From the perspective of multiculturalism, the development status of college English teaching reflects the importance of multicultural infiltration. The following explores college English teaching strategies from the perspective of multiculturalism from three aspects: establishing “double qualified” teachers, paying attention to mother tongue and cultural differences, establishing diversified teaching concepts and establishing teaching culture evaluation system.

Infrastructure development policies have been criticised for lacking a deliberate pro-gender and pro-informal sector orientation. Since African economies are dual enclaves, with the traditional and informal sectors female-dominated, failure to have gendered infrastructure development planning and investment exacerbates gender inequality. The paper examines the effect of the infrastructure development index, the size of the informal economy, and the level of economic development on gender inequality. The paper applies the panel autoregressive distributed lag method to data on the gender inequality index, infrastructure development index, GDP per capita, and size of the informal sector for the period 2005–2018. The sample consists of 44 African countries. The research established that the infrastructure development index, its sub-indices, GDP per capita, and the size of the informal sector are crucial dynamics that governments need to consider carefully when formulating development policies to reduce gender inequality. The research found that investment in infrastructure in general, transport infrastructure, and energy infrastructure reduces gender inequality. infrastructure development has gender inequality increasing effects in some countries and gender inequality reducing effects in others. The pattern suggests that at the continental level a Kuznets-type patten in the relationship between gender inequality and infrastructure development, gender inequality and size of informal sector, and gender inequality and GDP per capita exists. Some countries are in the region where changes in these covariates positively correlate with gender inequality, while others are in the region where further increases in the covariates reduce gender inequality.

In the process of vocal music teaching, the level of a singer's aesthetic ability often determines their long-term development. Therefore, in the process of conducting vocal music teaching, it is necessary to pay more attention to the cultivation of students' musical aesthetic ability, improve students' understanding and mastery of music art from the ideological level, and achieve better teaching effects. This article will conduct research on the importance of cultivating aesthetic ability in vocal music teaching, and explore strategies from aspects such as absorbing life content and introducing musical instruments into teaching models. It is hoped to provide some help for related teaching work.

António Tapiés is considered a master artist in Spain with the same influence as Picasso, Miró and Dali. Throughout his artistic career, Antoni Tapiés has formed distinctive and personal artistic expression characteristics and forms of expression in his continuous development and changes. The development and aesthetic habits of contemporary art have also been influenced by his work. When we combine his creative background and learning process, we can more accurately analyze his mysterious artistic characteristics and unique forms of expression. When we combine the background and study process of Antoni Tapiés, we can more accurately analyze his mysterious artistic expressions and unique forms of expression.

As an important component of socialist culture with Chinese characteristics, excellent traditional culture is not only the "cradle" of cultural origin, but also the foundation of advanced socialist culture and ideological and political guidance for students. It is an indispensable part of socialist education. With the advent of the Internet era, it not only poses challenges to the ideological and political education of college students, but also provides opportunities for development. In the new era, by means of new ideas and new methods, integrating fine traditional culture into the course of "Chinese Traditional Flower Arrangement Art" can not only promote the effectiveness and attractiveness of the Chinese traditional flower arrangement art course, but also promote the students' ideological level and recognition of excellent traditional culture, and help students improve their cultural awareness and national self-confidence. Based on this, this article explores the strategy research of integrating cultural confidence into the course of "Traditional Chinese Flower Arrangement Art".

Lean (also referred to as the Toyota Production System, TPS) is considered to be a radical alternative to the traditional method of mass production and batching principles for maximising operational efficiency, quality, speed and cost. Many hospitals inspired from lean manufacturing to develop their process. They had many improvements in their process. Hospitals reduced their patient waiting times, defects, wastes related to inventory, staff movement and patient transportation by implementing. This study utilizes scientometric and bibliometric tools to analyze visually the literature published in the field of medical lean manufacturing from 2009 to 2023. The relevant articles published from 2009 to 2023 were retrieved from the Web of Science Core Collection, VOSviewer and R software were used for bibliometric analysis and visualization. The number of publications related to the research has been increasing year by year before 2021, and then showed a downward trend, including 418 articles from 64 countries and regions, 743 institutions, 198 journals, and 1766 authors. The United States, Italy, and England are the main publishing countries in this research field. The journal “International Journal of Lean Six Sigma” published the most papers (n = 21) about lean manufacturing in medicine, the author with the most publications is Teeling SP, and the most influential author is Improta G. The top three keywords are “Healthcare”, “Quality improvement” and “Management”. This study provides a comprehensive bibliometric analysis of lean manufacturing in medicine, which can help researchers understand the current research hotspots in this field, explore potential research directions, and identify future development trends.
