Internet of things (IoT) has emerged as the most popular technique that facilitates enhancing humans' quality of life. However, most time sensitive IoT applications require quick response time. So, processing these IoT applications in cloud servers may not be effective. Therefore, fog computing has emerged as a promising solution that addresses the problem of managing large data bandwidth requirements of devices and quick response time. This technology has resulted in processing a large amount of data near the data source compared to the cloud. However, efficient management of computing resources involving balancing workload, allocating resources, provisioning resources, and scheduling tasks is one primary consideration for effective computing-based solutions, specifically for time-sensitive applications. This paper provides a comprehensive review of the source management strategies considering resource limitations, heterogeneity, unpredicted traffic in the fog computing environment. It presents recent developments in the resource management field of the fog computing environment. It also presents significant management issues such as resource allocation, resource provisioning, resource scheduling, task offloading, etc. Related studies are compared indifferent mentions to provide promising directions of future research by fellow researchers in the field.

Since NFTs can be used like certificates due to the nature of blockchain, their use in various digital asset trading markets is expanding. This is because NFTs are expected to be actively used as a core technology of the metaverse virtual economy as non-transferable NFTs are developed. However, concerns about NFT security threats are also growing. Therefore, the purpose of this study is to investigate and analyze NFT-related infringement cases and to clearly understand the current security status and risks. As a research method, we determined NFT security areas based on previous studies and analyzed infringement cases and threat types for each area. The analysis results were systematically mapped in the form of domain, case, and threat, and the meaning of the comprehensive results was presented. As a result of the research, we want to help researchers clearly understand the current state of NFT security and seek the right research direction.

On May 1, 2019, the Minister of Health and Welfare announced publicly the first Comprehensive Plan of National Health Insurance (NHI). The Comprehensive Plan which is the 5-year plan including expenditure and revenue aspect of NHI, is desirable in 42 years of introduction of NHI and 30 years of universal coverage of NHI, though the Plan was late and had some conflict process. The Comprehensive Plan was established without evaluation of Moon's Care Plan, did not included to relationship with NHI and other health security systems, and did not have the blue print of NHI. The Plan was not sufficient in content of adequate health care utilization and relationship with service benefit and cash benefit. The Comprehensive Plan should be modified in considering the blue print of NHI and national healthcare system with participating stakeholder in turbulent environment-low fertility, rapid ageing, low economic growth rate, era of non-communicable diseases, unification of the Korean Peninsula, and 4th industrial revolution. Therefore, I suggest to establish the President's Committee of Improving Healthcare System for the blue print of health care and NHI.

Cyber-Physical Systems (CPS) are introduced as complex, interconnected systems that combine physical components with computational elements and networking capabilities. They bridge the gap between the physical world and the digital world, enabling the monitoring and control of physical processes through embedded computing systems and networked communication. These systems introduce several security challenges. These challenges, if not addressed, can lead to vulnerabilities that may result in substantial losses. Therefore, it is crucial to thoroughly examine and address the security concerns associated with CPS to guarantee the safe and reliable operation of these systems. To handle these security concerns, different existing security requirements methods are considered but they were unable to produce required results because they were originally developed for software systems not for CPS and they are obsolete methods for CPS. In this paper, a Security Requirements Engineering Methodology for CPS (CPS-SREM) is proposed. A comparison of state-of-the-art methods (UMLSec, CLASP, SQUARE, SREP) and the proposed method is done and it has demonstrated that the proposed method performs better than existing SRE methods and enabling experts to uncover a broader spectrum of security requirements specific to CPS. Conclusion: The proposed method is also validated using a case study of the healthcare system and the results are promising. The proposed model will provide substantial advantages to both practitioners and researcher, assisting them in identifying the security requirements for CPS in Industry 4.0.
