It delves into both historical developments and prospective transformations and begins with a retrospective analysis of Taiwan's AI-related legislation before the post-pandemic era. Subsequently, it focuses on a critical aspect of Taiwan's AI legal framework during this era, including two pivotal documents in Taiwan: the \"AI Basic Act\" and the \" Reference Guidelines for the Use of Generative AI in the Executive Yuan and its Subordinate Agencies and Affiliated Institutions”. Both have recently garnered widespread attention, marking a crucial step towards navigating the evolving landscape of artificial intelligence. Finally, this article offers insights into the prospective evolution of Taiwan's legal landscape pertaining to AI. The formulation of the \"AI Basic Act\" is pivotal in setting fundamental norms for AI development in Taiwan. This draft is significant with its 24 articles aimed at fostering a trustworthy environment and promoting diverse AI utilization. It ensures that Taiwan's high-tech advancements align with global standards. On the other side, the “Reference Guidelines for the Use of Generative AI” are designed to regulate the administrative agencies in response to the widespread application of generative AI. Furthermore, since 2023, the Personal Data Protection Act and Criminal Code, among others, have all been amended to include provisions related to AI technology, reflecting the apparent impact of AI on the legal system. Given the novelty of AI in society, prioritizing the creation of a basic act is crucial. Such legislation defines AI in Taiwan, establishes ethical principles, outline development directions, and provides fundamental norms. It will serve as a cornerstone for shaping and revising other policies and laws to navigate the evolving landscape of AI.","PeriodicalId":301862,"journal":{"name":"International Journal of Membrane Science and Technology","volume":"11 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140269487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preventing tax loss through inspections can be difficult due to missing or incomplete taxpayer data from transaction processing servers. Explaining undeclared or incompletely declared revenue in online trading transactions on the server or the Internet can be challenging, especially for retail activities and service provision for businesses and individuals selling on social networking. In Vietnam, the Tax Management Law 2019 established the tax rates online retailers must pay. However, tax collection for social network retailers still depends on tax authorities encouraging them to self-declare their revenue. Current research and practice show that very few sellers on social networks participate in the self-declaration of revenue to pay taxes. Moreover, few studies focus on factors affecting the participation of online retailers in Vietnam in tax declaration and payment, especially those selling on social networks, and most lack a solid theoretical foundation. Through a review of related studies, this research has identified several factors that affect tax payment decisions for retailers on social networks in Vietnam. The study also provides several recommendations to promote and enhance retailers’ tax declaration and payment decisions on social networks in Vietnam.","PeriodicalId":301862,"journal":{"name":"International Journal of Membrane Science and Technology","volume":"273 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140427927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: This study aimed to investigate the interplay between emotional intelligence (EQ), anger, and violent behavior among medical students. Specifically, it sought to analyze the association between emotional intelligence levels and the expression of anger and violence, as well as to compare emotional intelligence and aggression tendencies between male and female students. Methods: A correlational research design was employed, utilizing online surveys as the data collection method. A total of 200 medical students aged between 19 to 30 years participated in the study. Emotional intelligence, anger expression, and violent behavior were measured using standardized scales. Statistical analyses including descriptive statistics, Pearson correlation, and independent sample t-tests were conducted using SPSS 23.0 software. Results: The findings revealed a significant negative correlation between emotional intelligence and both anger expression and violent behavior. Male students exhibited higher levels of anger and violent behavior compared to female students. Emotional intelligence scores were lower in male students, indicating a potential contributing factor to their heightened aggression tendencies. Conclusion: The study provides empirical evidence supporting the association between emotional intelligence, anger, and violence in medical students. Lower emotional intelligence levels were linked to increased anger expression and violent behavior. These findings underscore the importance of integrating emotional intelligence education programs into medical curricula to mitigate aggression tendencies and promote healthier interpersonal relationships among students.","PeriodicalId":301862,"journal":{"name":"International Journal of Membrane Science and Technology","volume":"92 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140426539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
