During manned space missions, an environmental control and life-support system (ECLSS) is employed to meet the life-supporting requirements of astronauts. The ECLSS is a type of hierarchical system, with subsystem—component—single machines, forming a complex structure. Therefore, system-level conceptual designing and performance evaluation of the ECLSS must be conducted. This study reports the top-level scheme of ECLSS, including the subsystems of atmosphere revitalization, water management, and waste management. We propose two schemes based on the design criteria of improving closure and reducing power consumption. In this study, we use the structural entropy method (SEM) to calculate the system order degree to quantitatively evaluate the ECLSS complexity at the top level. The complexity of the system evaluated by directed SEM and undirected SEM presents different rules. The results show that the change in the system structure caused by the replacement of some single technologies will not have great impact on the overall system complexity. The top-level scheme design and complexity evaluation presented in this study may provide technical support for the development of ECLSS in future manned spaceflights.

The article analyzes the problems of the manifestation of risks of shadow and criminal activity in the life support system of citizens of the Russian Federation, the dissemination of which requires the development of effective measures to prevent and eliminate them. The most important issue is the formation of an effective economic security system with an emphasis on the new quality of life support for citizens of the Russian Federation in an adequate combination with the high growth rate of NTP in the Russian economy. The new technological structure emerging from the new achievements of scientific and technological progress involves the harmonization of the pace of scientific and technological development, combined with an adequate improvement in the quality of life support for citizens performing such achievements. Owing to this fact formation of new quality of the housing and communal services (HCS) as bases of life support of citizens becomes a prerequisite of increase in performance and intellectualization of human work. With this in mind, early recognition, prevention and elimination of risks of shadow and criminal activities in the housing and communal services system (housing and communal services) is considered as a significant mechanism to increase the effectiveness of the system of comfortable life support for citizens of the Russian Federation. The existing lag in the development of a high-quality and comfortable system for providing citizens of Russia on the basis of housing and communal services, the subject of which is the provision of quality and comfortable services, influenced by numerous risks of shadow and criminal influence, becomes a condition for intensifying economic development and increasing labor productivity on this basis. The need to develop and use modern scientific and technical achievements, especially in the field of digitalization, is emphasized in order to increase the efficiency of the economic security system of housing and communal services organizations based on innovative control mechanisms - internal control, audit, compliance control, taking into account financial investigations in order to prevent and eliminate the risks of shadow and criminal activities in the housing and communal services system.

Background: Portable life support system is used in the battlefield, disaster and in other special circumstances such as in space exploration, and underground survey to give the wounded a life support. The most dangerous period for the injured is the first hour after an injury, which is a crucial time for treatment. If the patient's vital signs were stabilized, more than 40% of the injured could be saved. The staff can efficiently complete the task if they get effective and stable vital signs during the operation. Therefore, in order to reduce the risk of disaster and battlefield mortality to improve operational safety and efficiency, it is necessary to study the portable life support system. Objective: The study aimed to provide an overview of recent portable life support system and its characteristics and design. Methods: This paper introduces the patents and products related to a portable life support system, and its characteristics and application. Results: This paper summarizes five kinds of portable life support systems which are box type, stretcher type, bed type, backpack type and mobile type. Moreover, the characteristics of different portable life support systems are analyzed. The paper expounds the problems of different types of portable life support systems and puts forward improvement methods to solve the problems. Finally, the paper points out the future development of the system. Conclusion: Portable life support system plays an increasingly important role in health care. In terms of the structure, function and control, further development and improvements are needed, along with the research on portable life support system.
