The impact of developing pop music on music infrastructure construction and education systems

Sustainable development within music education is essential, particularly in ensuring that popular music can continually and effectively serve educational systems. This research aims to 1) examine pop music chord progression, 2) develop a chord progression book specifically for teaching music students, and 3) evaluate the effectiveness of this educational tool in improving music composition skills. A mixed-methods approach, incorporating both qualitative and quantitative research, was used. Research tools included an interview guide, Ioc forms, a textbook, and a performance assessment form. Interviews were conducted with five experts in pop music composition, while a group of 14 undergraduate music students participated in the experimental study. These methods evaluated how teaching popular music chord composition enhances students’ practical composition abilities. The findings indicate that 1) chord composition in popular music primarily involves five aspects: melody, rhythm, chord structure, music form, and melody development techniques, with melody and chord as the foundational elements; 2) the chord progression textbook for popular music differs from traditional composition theory texts, combining theory and practical application with a focus on chord progression techniques; and 3) instruction in popular music chord composition significantly enhances students’ skills in melody creation, production, and listening, ultimately fostering practical music creation abilities. This study supports the sustainable integration of popular music in both music infrastructure construction and music education system development, offering insights into how such integration can drive long-term advancements in music education.

In the contemporary educational environment, stimulating students’ interest has become the key to enhancing teaching effectiveness. Especially in the field of music education, traditional teaching methods often fail to fully mobilise students’ enthusiasm. This paper discusses how to refresh the traditional mode of music education by integrating popular music and electronic music to stimulate students’ learning interest and improve teaching efficiency. We analyse the current challenges facing music education, especially the shortcomings in interest and ability development, and propose a series of reform measures. These measures include the use of multimedia technology, the creation of a positive learning environment, respect for student agency, and the implementation of positive and timely assessment. Through empirical research, we find that introducing popular and electronic music into the classroom not only enhances students’ interest in music learning, but also their creativity and critical thinking skills. Finally, the paper emphasises the key role of teachers in creating and sustaining student interest and the importance of adopting innovative teaching methods in modern music education.

Impact of Population Aging on Economic Growth and Coping Strategies

While the pace of economic development is accelerating, the phenomenon of population aging in China is becoming more and more serious, which is mainly due to the demographic structure of China is changing, and the situation of negative population growth is occurring due to the decline in the fertility rate. When the aging of the population is more serious, it will lead to the reduction of the econom_x005fically active population, which will seriously affect the labor productivity, and will have a serious impact on economic growth. Therefore, population aging not only represents a change in the demographic structure of China, but also affects economic development. In view of this, this paper will analyze the measures to cope with the impact of population aging on economic growth, starting from the impact of population aging on economic growth.

Can highway development mitigate regional decline in South Korea?—Focus on economic development and population inflow

South Korea has experienced rapid economic development since the 1960s. However, pronounced regional disparities have concurrently emerged. Amid the escalating regional inequalities and persistent demographic challenges characterized by low fertility rates, regional decline has become a pressing issue. Therefore, the feasibility of expanding transportation networks as a countermeasure to regional decline has been proposed. This study utilizes the synthetic control method and spatial difference-in-differences methodologies to assess the impact of the 2017 opening of Seoul–Yangyang Expressway on economic development and population inflow within Hongcheon-gun, Inje-gun, and Yangyang-gun. The purpose of this study is to evaluate the effectiveness of highway development as a policy instrument to mitigate regional decline. Findings from the synthetic control method analysis suggest a positive impact of the opening of the expressway on Hongcheon-gun’s Gross Regional Domestic Product (GRDP) in 2018, as well as Yangyang-gun’s net migration rates from 2017 to 2019. Conversely, the spatial difference-in-differences analysis, designed to identify spillover effects, reveals negative impacts of the highway on the GRDP and net migration rates of adjacent regions. Consequently, although targeted transportation infrastructure development in key non Seoul Metropolitan cities may contribute to ameliorating regional imbalances, results indicate that such measures alone are unlikely to suffice in attracting population to small- and medium-sized cities outside the Seoul Metropolitan Area.

Polymer bio-weathering and biodegradation induced by soil plastisphere: A comprehensive review

The plastisphere is a newly recognized geospheric layer at a planetary scale, characterized by the presence of microorganisms, primarily as biofilms, that colonize inert and poorly decomposable organic matter, particularly plastics. The stability and diversity of substrate plastic fosters a consistent evolutionary trend among microorganisms, leading to specialized ecological niches that enhance particular physiological traits for plastic degradation. Biofilms have been observed on various types of plastics, including both conventional petroleum-based polymers (like polyethylene and polystyrene) and bioplastics (such as polyhydroxyalkanoates). The characterization of plastisphere objects is crucial and should be conducted with geodetic referencing and spatio-temporal metrics to understand the impacts of climatic and meteorological factors. The dynamic nature of species succession in response to environmental changes necessitates advanced analyzes of microbial communities’ potential for plastic degradation. The spatial turnover of core and occasional taxa complicates the precise identification of microbial functions within these communities. The question of “What is in the plastisphere?” emphasizes the need for detailed biogeographical and chemical mapping due to the small size and localized nature of microplastic particles. It is important to differentiate when plastics serve as growth resources (biodegrading) versus mere substrates for microbial growth, raising the question of “Food or just a free ride?” The geochemical and aerochemical activities within the plastisphere are crucial for understanding its broader environmental impacts. These activities include nitrogen metabolism and the biogeochemical cycling of nitrogen, phosphorus, and carbon, which encompasses greenhouse gas emissions associated with plastic degradation. Additionally, trace metals can accumulate in the plastisphere, potentially facilitating photo-Fenton processes that may occur on microplastic surfaces when exposed to sunlight.
