The 2020 year began with such a situation, in the sense that United States of America and Iran, which have been for a long period in relations not among the most well, have arrived at a moment that could represent, to a very large extent, the starting point of a conflict that will enter in the world history. The elimination of a very important Iranian general by US troops in early January 2020, by a surprise attack amonk Iraqian teritory, markedly aggravated relations between the United States of America and Iran, but also between the great world power and Iraq or other major global players who have harshly criticized the US attack.</abstract>

Removal of a General – The Rebirth of a Latent Conflict Between Two Sovereign States: USA and Iran

<abstract xmlns="http://www.w3.org/1999/xhtml">Although the health sector is a great contributor to the well-being status of every individual and community as a whole, and it is recognized that good health supports the economy, the idea of connecting it with the national security was not very much promoted by the public policymakers, nor by the academics. Over the last three decades, not only that the situation has started to change, but even the concept of health security has gained acceptance and attractiveness. Nevertheless, there is a great debate in theory and practice concerning the real meaning of the concept and the way of understanding it by the professionals from different domains connected with the public health sector. Not to mention that its importance is brought into discussion mainly in times of crisis and the disagreement regarding its content and scope is much deeper between developed and developing countries. This paper proposes to make the necessary distinction between the concepts that constitute the foundation of the specific analysis, but without treating them in a separate way. Also, by dealing with the concept of health security, it aims at highlighting the role of government in the process and last, but not least, to emphasize the need of international cooperation in the global age.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The topic addressed in this article is a current one and modern armies discuss it a lot and many analyses and comments can be made. In the article, the author presents the general framework of operations in the urban environment and starting from the operational requirements mandatory to conduct such operations he analyzes the prospects that such operations have in future military operations and proposes directions for action necessary for the effective training of the subunits within the Romanian Land Forces.</abstract>

Challenges Faced by the Romanian Land Forces Regarding Training for the Operations in the Urban Environment

<abstract xmlns="http://www.w3.org/1999/xhtml">The last decades of the evolution of mankind have undergone spectacular changes in technological progress; the age in which we live is paradoxical, tumultuous, a world of informational abundance, subject to continuous change. With this evolution, threats, risks and vulnerabilities have gained new registers of understanding and manifestation. These changes in the methods of achieving the goal, specific to the 21st century, make it necessary to know and understand the new needs, how to manifest them in the online environment and the risks arising from satisfying them. Changes in the technological sphere have also led to behavioral changes. Humans behave differently in different environments, and the online environment offers unlimited possibilities with effects that we still cannot fully interpret. The social networks initially aimed to create an optimal environment in which people have the chance to be connected, to share ideas, thoughts, experiences, and memories. The purpose of this article is to highlight both the naivety of people when they work in the online environment, how this naivety can be used to obtain certain results at a strategic level, as well as the effects / impact that our actions in the online environment can have.</abstract>

Needs in the Online Environment of the 21st Century

<abstract xmlns="http://www.w3.org/1999/xhtml">Firefighters have a demanding and difficult mission both physical and mental so their training must be rigorous and well prepared, therefore they should have good physical resistance, strength, speed, and coordination. Our study focuses on the 4 x 100 m race with obstacles and how should firefighters physically prepare for the race. We had two different samples that form the first and second team of ISU Sibiu in the competition of firefighters of 4 x 100 m race with obstacles, formed by 10 males with age of 30 ± 3.5 years old with experience in this kind of competitions between 2 and 7 years. We presented our training program and the effects on the results of our athletes and also analyze the efficiency of developing motor qualities such as strength, speed, resistance and coordination. The results show relatively good improvements in the performance time in any of the fourth exchanges and also in the motor qualities level. Conclusions of our research present the efficiency of training athletic skills and also the motor qualities in obtaining better results at the 4 x 100 m race with obstacles.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The process of identification of radioactive isotopes using gamma ray spectrum produced by scintillation detectors is a fundamental problem in physics. Military applications also require fast and efficient methods, especially in field conditions, for identifying unknown isotopes. The fundamental problem is the relationship between the observed gamma ray spectrum given by the detector and the real spectrum. This problem can be treated as a mathematical problem. The relationship between the real and the observed spectrum can be described by a linear algebraic equation system. In the previous article Cholesky-decomposition has been applied. In this article one more independent mathematical tool is proposed to solve the linear system efficiently.</abstract>

In the cyberterrorism activities, either disruptive and/or destructive, people tend to be the softest link in security chain. Therefore, the threat source would be less important compared with the way of protection. Many efforts have been performed in strengthening the farend-recipients’ infrastructure of communications and critical information systems. Amongst, is the Geo-Encryption Cryptographic Algorithm. It depends on adding a new layer of security by using the most vulnerable signals to cyber-attacks, which is the GPS signals. Hence, its strength came out from its weakness. The Geo-encryption technique assumes the use of anti-jam and anti-spoof GPS receivers, which without, the model would be of no added value to the end-users’ security. In this study, an assessment of the model performance among vulnerability challenges is conducted, showing the characterization of the GPS tool in such model being a solution while it is simultaneously a vulnerable target. A special focus was put in the GBAS Landing System (GLS) performance, in both military and civilian aviation aspect.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Recent days there are many projects of UAV urban applications, moreover, although in different habited area. Several concepts like urban drone taxi, flying boards, flying bikes, etc. are in phase of prototype system test and evaluation. As part of the modern robotization, UAVs are in the focus of attention of numerous scientists. UAVs, as special platforms are widely used by the Military in different scenarios and different flight missions. Capabilities of UAVs used in non-military applications (i.e. Police applications, disaster management applications, border control, firefighter applications, etc.) will serve well the idea of UAV 3D (Dirty-Dull-Dangerous) application. The purpose of the author is to derive those low altitude UAV flight regimes when low altitude flight automation in necessary due to flight safety aspects, or, due to any existing regulations, and, finally, find and propose flight paths of the UAV better fitting given mission of the UAV.</abstract>

Flight Path Planning for Small UAV Low Altitude Flights

<abstract xmlns="http://www.w3.org/1999/xhtml">University “Ovidius” of Constanța, Faculty of Medicine, in collaboration with the Diving Center, has conducted several research studies regarding the evolution of the vital functions of divers in the hyperbaric environment. Their breathing is constantly adapting to withstand the physiological changes. Reducing the residual volume of the lungs is an essential parameter for improving respiratory function in the event of increased physical effort. The residual volume cannot be determined by spirometry. The medical researchers and engineers developed an original test plan and verified the residual volume of the subjects, by experimental determinations on groups of divers, during simulated diving, with air, at 18 m, in the Hyperbaric Complex of the Diving Center. The study is useful in the prevention of occupational diseases specific to divers and in knowing their limits of adaptation to the hyperbaric environment.</abstract>
