Carbon monoxide (CO) is a toxic gas, and environmental pollutant. Its detection and control in residential and industrial environments are necessary in order to avoid potentially severe health problems in humans. In this review paper, we discuss the importance of furthering research in CO sensing technologies for finding the proper material with low-range detection ability in very optimum condition. We build our discussion through the perspective of a cyber-physical system (CPS) modeling framework, because it provides a comprehensive framework to model and develop automated solutions for detection and control of poisonous chemical compounds, such as the CO. The most effective CO sensors, then, can be used in CPS network to provide a pathway for real-time monitoring and control in both industrial and household environment. In this paper, first, we discuss the necessity of CO detection, the proposal of a basic CPS framework for modeling and system development, how the CPS-CO model can be beneficiary to the environment, and a general classification of the various CO detection mechanisms. Next, a broad overview emphasizes the sensitivity, selectivity, response and recovery time, low concentration detection ability, effects of external parameters and other specifications that characterize the performance of the sensing methods proposed so far. We will discuss recent studies reported on the use of metal oxide semiconductor (MOS) sensing technologies for the detection of CO. MOS based micro-sensors play an important role in the measurement and monitoring of various trace amounts of CO gas. These sensors are used to sense CO through changes in their electrical properties. In addition to MOS based sensors, optical sensing methods have recently become popular, due to their increased performance. Hence, a brief overview of newly proposed optical based CO detection methods is provided as well.

Place of monitoring and control of risks of financial stability of the state in the system of ensuring financial security of the state was substantiated. Methods of identifying threats to Ukraine's financial security through the current and strategic analysis of financial system development indicators were considered. Tendencies of economic development of Ukraine in the context of revealing sources of threats to financial stability of the state were analyzed. Dynamic analysis of the actual values of the financial security indicators of Ukraine as a whole and its separate components had been carried out. Threats to Ukraine's financial security were identified based on comparative and trend analysis. Reasons for the critical state of debt, banking and monetary security in the financial structure and the preconditions for the emergence of systemic threats had been investigated. Systematization of risks and threats to Ukraine's financial security by its components had been carried out. Influence of systemic threats in the financial sphere on the economic security of the state was generalized. International experience of monitoring financial stability of the state was analyzed. Additional risks to the national financial system are associated with the globalization and digitization of the state financial system that are not taken into account by valid methodological recommendations for calculating the level of economic security of Ukraine were highlighted.

Due to the importance of the environment on animal production and thus environmental control, the study aims to build a system for monitoring and control the meteorological variables, temperature and relative humidity, low cost, which can be associated with an evaporative cooling system (ECS). The system development included all the stages of assembly, test and laboratory calibration, and later the validation of the equipment carried in the field. The validation step showed results which allowed concluding that the system can be safely used in the monitoring of these variables. The controller was efficient in management of the microclimate in the waiting corral and allowed the maintenance of the air temperature within the comfort range for dairy cattle in pre-milking with averaged 25.09 ºC during the afternoon. The equipment showed the lower cost (R$ 325.76) when compared to other middle market (R$ 450.00).

Cases concerning the substitution of meat raw material also occur in Indonesia and are quite common. Therefore, careful monitoring and control that needs to be done on the meat products. Screening or sampling products on the market should be conducted periodically to ensure the safety of consumers and society in general. Such screening should be done accurately. This study aimed to analyze the composition of meat in processed products in traditional markets in Bandung using PCR method. This study was using four specific primers to detect four different species. Screening is done on samples of meatballs from several markets. The results showed the presence of several samples that contain meat of some species. based it can be concluded that the substitution of raw materials processed meat products also occurs in the traditional market in the city of Bandung, and the PCR method referred to can be used as the basis for the development of detection methods of food security in Indonesia.

The progress of technology and computer surveillance systems at this time has provided a significant positive contribution in all fields to support and improve the performance of a system. One of the technological advances in the field of computers is computer monitoring and control. Computer monitoring and control systems used in computer laboratories at the College of Information and Computer Management (STMIK) Palangkaraya still use a paid system or must first purchase to be able to use it in every computer laboratory room, so that not all computer laboratory rooms can be monitored using the system because there are not a few costs to purchase the system. Therefore, to supervise all the STMIK Palangkaraya laboratory rooms, a computer monitoring and control system is built that can be used free of charge. The software development method used is the System Development Life Cycle (SDLC) method with a waterfall model development approach. The programming language used is Microsoft Visual Basic. Based on the results of tests on the system that was built to produce all the processes and facilities contained in the system running in accordance with the test items that have been set.

Personal computers (PCs) are a powerful resource in the EM Laboratory, both as a means of automating the monitoring and control of microscopes, and as a tool for quantifying the interpretation of data. Not only is a PC more versatile than a piece of dedicated data logging equipment, but it is also substantially cheaper. In this tutorial the practical principles of using a PC for these types of activities will be discussed.The PC can form the basis of a system to measure, display, record and store the many parameters which characterize the operational conditions of the EM. In this mode it is operating as a data logger. The necessary first step is to find a suitable source from which to measure each of the items of interest. It is usually possible to do this without having to make permanent corrections or modifications to the EM.
