Abstract

The paper evaluates potential applications of blockchain technology in enhancing the security and reliability of Wireless Sensor Networks (WSNs). The existing vulnerabilities in WSNs, such as concerns regarding data integrity and security, demand innovative security solutions. Through systematic analysis, this paper provides valuable insights to expand understanding of WSNs security, explaining the feasibility and benefits of deploying blockchain technology. Possible attacks in the networks are classified to point out either risks or potential solusions to protect the networks. By exploring the integration of Blockchain within WSNs, the paper highlights its potential to minimize various security risks. In addition, this work discusses the challenges and considerations associated with implementing Blockchain in WSNs. Overall, this paper contributes on securing WSNs and underscores the role of blockchain technology as a promising way for enhancing security of WSNs.

Abstract

This research attempts to comprehensively analyze the role and requirements of people's participation in the legislative process during Vietnam's state of emergency. Using conventional, trusted legal research methods, most notably desk review of legislation and case law analysis, this research affirms that, during a state of emergency, procedures involving public participation cannot follow the usual process. However, a pandemic must never be used as an excuse to erode democratic principles, and only when citizens actively take part in regular circumstances will they have the motivation to engage during emergencies. With Vietnam, many legal documents were issued by executive agencies instead of the National Assembly. Therefore, although the timely issuance of policies and laws was ensured during the pandemic, the principles of the legislative process were not fully upheld or implemented, leading to many debates regarding the legality of the documents issued during this period. In that sense, this research focuses on analyzing the current legal system and several typical cases of law enforcement in Vietnam and other countries to identify the legal gap and propose solutions to improve the legal framework on this issue in Vietnam.

Abstract

Purpose of the study: The aim of this research is to improve students' learning outcomes in Mathematics by using the Problem Solving method. Methodology: The research conducted used Classroom Action Research. Data were obtained from qualitative and quantitative data. Data collection techniques included observation, testing, documentation, and interviews. The data analysis method used both qualitative and quantitative data. Main Findings: Based on the results of data analysis, it is known that, after using the Problem Solving method, student learning outcomes have increased. This can be seen from the results of the pre-test and post-test given to students, which always increased in each cycle. The increase in student learning outcomes in cycle 1 was 71.88% and in cycle II 87.10%. There was an increase in the completeness of student learning outcomes by 5.31%. Novelty/Originality of this study: This study introduces a structured problem-solving instructional model implemented through classroom action research to regularly improve students' mathematics learning outcomes. Unlike previous studies, it integrates iterative reflection cycles with authentic classroom problems, providing practical evidence on how problem-solving instruction directly enhances students' engagement, conceptual understanding, and achievement.
