Virtualisation in cloud computing is vital for maintaining maximum resource utilization and easy access to operation and storage management of components. Platform virtualisation technology has the potential to be easily implemented with the support of scalability and security, which are the most important components for cloud-based services. Virtual resources must be allocated to a centralized pool called the cloud, and it is considered as cloud computing only when the virtual resources are orchestrated through management and automation software. Therefore, research and development on the latest technology for such a virtualisation platform provides both academia and industry the scope to deploy the fastest and most reliable technology in limited hardware resource. In this research, we reviewed and compared the popular current technologies for network and service management and automation technology.

Knowledge of the technology, characteristics, and market trends of the latest CPUs used in smartphones, computers, and supercomputers and the research trends of leading US university experts gives an edge to policy-makers, business executives, large investors, etc. To this end, we describe three topics in detail at a level that can help educate the non-majors to the extent possible. Topic 1 comprises the design and manufacture of a CPU and the technology and trends of the smartphone SoC. Topic 2 comprises the technology and trends of the x86 CPU and supercomputer, and Topic 3 involves an optical network chip that has the potential to emerge as a major semiconductor chip. We also describe three techniques and experiments that can be used to implement the optical network chip.

Climate change due to global warming is affecting the global environment. The fishery industry is highly dependent on the natural environment, so the fishery industry is increasingly volatile due to the rapidly changing climate change. At the same time, consumers' anxiety due to marine pollution such as microplastics, radioactivity, and heavy metals are increasing. Accordingly, cell-based seafood are being proposed as an alternative for the sustainable use of seafood resources. Cell-based seafood manufactured through a process of differentiation and proliferation using cells isolated from actual seafood and cell, scaffold, media, and bioreactor technologies are organically connected to each other. This review summarizes the latest research status of cell-based seafood. Based on this, suggests a development direction for cell-based seafood to properly settle in the future market.

In the industrial field nowadays the information that needs to be handled arc increasing and requires faster speed in contrast with PLC(Programmable Logic Controller) or DCS(Distributed Control System) based control systems these days. The work environment these days are mostly based on PC, so the control systems are wanted in PC. At Fieldbus used automated systems performing distributed process control by PC performs and combines into one system in order to maximize the increase of productivity, lower the expense, planning constructing and maintaining the reliance of automation. These latest automation systems unites process, makes distributed control process able, and can control and supervise at remote PC.
