The scientific objective of this study is to demonstrate how a hybrid photovoltaic-grid-generator microsystem responds under transient regime to varying loads and grid disconnection/reconnection. The object of the research was realized by acquiring the electrical magnitudes from the three PV systems (25 kW, 40 kW, and 60 kW) connected to the grid and the consumer (on-grid), during the technological process where the load fluctuated uncontrollably. Similar recordings were also made for the transient regime caused by the grid disconnection, diesel generator activation (450 kVA), its synchronization with PV systems, power supply to receivers, and grid voltage restoration after diesel generator shutdown. Analysis of the data focused on power supply continuity, voltage stability, and frequency variations. Findings indicated that on-grid photovoltaic systems had a 7.9% maximum voltage deviation from the standard value (230 V) and a frequency variation within ±1%. In the transient period caused by the grid disconnection and reconnection, a brief period with supply interruption was noted. This study contributes to the understanding of hybrid system behavior during transient regimes.
Common prosperity of spiritual life is a value pursuit of human beings for a better life and a better society. Promoting common prosperity in people's spiritual life has become the internal driving force for the innovation and development of ideological and political education in the new era. In terms of value implication, ideological and political education to lead the common prosperity of spiritual life mainly provides ideological guidance, establishes value coordinates and cultivates mental tone. Its core meaning is to enrich the connotation of common prosperity of spiritual life with scientific theory, standardize the pursuit of common prosperity of spiritual life with value concepts, and clarify the realm of common prosperity of spiritual life with aesthetic consciousness. Its realization path is mainly theoretical education, cultural edification and practice.
The recent coronavirus-19 pandemic has highlighted the need for a global digitally enabled healthcare advancement infrastructure to ease e-coverage in the future and reduce human losses, facilitating access to high-quality and cost-effective health solutions. As the concept of a virtual healthcare system is still premature, it would have required noteworthy speculation in technologies and an overhaul of most of the current classical healthcare infrastructure, policies, and systems around the globe. Aims and objectives: This study aims to create a viable autonomous virtual universal health care system to modify the comfort of health care through emerging digital and communication innovations to fulfil consumer needs. Methodology: This study falls under the fact-finding category, which encompasses an exploratory approach with literature examination, limited field visits with informal interviews with local key authorities, and an initial assessment of current circumstances to examine the possibility of application of virtual health coverage. Findings: This study discovered that it is imperative to organize and develop the prospected healthcare system at the country level to be governed by international organizations as speculatively it is functioning in comparative improved healthcare systems across the world, which should be based on special processing of the prospected six types of data with their operationalization to serve multidisciplinary bunches by e-governance and exchanges between distinctive measurements. It requires more dependence on digital infrastructure and learning materials through electronic resources and ordinary techniques. Among other effective components for the development of virtual health coverage, are the applications of digital technology, the middle utility of voice and brief advising framework, complex functionalities, and applications of fifth generations (5Gs) arranged into universal servers attached to GPS-appropriate for sound choice and high-quality measures. Recommendations: This study recommends the construction of a virtual healthcare system by utilizing the proposed Electronic domestic medical adviser, virtual clinics, or “e-health incubators” which will allow individuals to relate through the web rather than the face-to-face institutive fragmented structure systems.
This research reviews the environmental, social, and governance (ESG) performance of corporate social responsibility (CSR) and technology innovation development, and analyzes the impact of technology innovation on ESG performance and its influencing mechanism. In additional, the main purpose of this study is to gain an understanding the relationships of ESG performance, CSR and technology innovation in Art industry. We found that technology innovation impact CSR of art firm, and ESG performance with the moderating variable of technology innovation has a significant and positive impact on CSR. Likewise, the study is based on primary panel data collected from 161 consumer, product and service manufacturing companies through an electronic questionnaire (Google, Microsoft online survey) with five-point Likert measurement scale. The exploratory factor analysis is proposed to be carried out using IBM SPSS 27.0 and the confirmatory factor analysis (CFA analysis) is proposed to be carried out using SmartPLS.4.0 analysis software, and this study investigate the measurement factors and the reliability of the construct items and to validate the factorial structure of the research variables. Moreover, digital technology and CSR has the potential to contribute to this impact. Based on these findings, we propose relevant ESG performance recommendations to improve technology innovation and CSR. Our findings offer an excited knowing and learning of the impact of ESG performance, CSR and technology innovation in Chinese art industry. Furthermore, this study extends stakeholders theory and Schumpeter’s Innovation Theory by proving their utility in the perspective of CSR, ESG performance.
This article focuses on studying how transportation connectivity affects Vietnam’s trade with Association of Southeast Asian Nations (ASEAN) countries. By using a gravity model, the article applies fixed effects (FE) and random effects (RE) to analyze panel data on trade, GDP, tariffs, border effects, and indicators. The number represents Vietnam’s transport connectivity with ASEAN countries from 2004 to 2021. Research results show that transport connectivity hurts Vietnam’s trade with other countries. ASEAN. The article proposes solutions for the Government and Vietnamese export enterprises to promote intra-ASEAN trade in the direction of increasing the added value of Vietnam’s imported and exported goods within ASEAN countries and balancing between Developing intra-ASEAN and foreign trade.
The issue of urban land management in the world in general and in Africa in particular has been exacerbated by the liberalization of land practices and the commodification of land, which has led to an increase in corrupt practices within land institutions in all cities. A mixed methodology was employed, combining a comparative case study of secondary towns with a quantitative survey of 559 landowners in the towns of Bohicon and Sokodé. In-depth interviews were conducted with 31 informants, who were surveyed on the land acquisition process, the individual determinants influencing corrupt practices, and the institutions most involved in these practices. The findings revealed that the acquisition of a formal title conferring property rights in both cities necessitates the completion of several steps. Corrupt practices are present at almost every stage of the transaction. The application of logistic regression models to the independent variables indicates that age and profession are highly significant in the sociodemographic characteristics of those most susceptible to engaging in these practices. Formal land administration institutions are the most involved in these types of everyday corruption. These practices are ultimately linked to people’s life paths and cannot therefore be combated without psychosociological education and the promotion of ethical behavior among all stakeholders, particularly among those who demand services.
