Thermoeconomics combines the concepts of economics and thermodynamics to assess the cost formation process of thermal systems. It has great applicability in the allocation, optimization and diagnosis of product costs. However, some aspects need to be gathered and solved, to have common criteria for its implementation. That is precisely what happens with dissipative components, which are part of cooling systems being so that different criteria are given to evaluate their impact in the cost distribution. In this paper, the state of art regarding the application of thermoeconomics in simple cooling systems is briefly evaluated, by giving the main characteristic of each approach, resolving that there is no a common criterion on the subject of the treatment of dissipative equipment and, therefore, neither on the costs accounting. Therefore, this work compiles and compares the different thermoeconomics methodologies. Consequently, it aims to serve as a tool for the appropriate selection of the thermoeconomics methodology for the analysis of real cooling systems.

The urbanization of territories and the increase in density of urban development cause the necessity of introduction of improved structural solutions into the construction practice. This is also connected with both the erection of higher buildings with longer span structures and the use of non-standard methods for the analysis of structures. The introduction of modern structural patterns lessens considerably the weight of structures, reduces the consumption of materials and cuts the construction production costs. At the same time, the responsibility for the construction projects enhances. A systematic control over the state of structures including a quasi-continuous one, allows us to reveal the very beginning of destructive processes and to take measures for their liquidation. One of monitoring methods is the tachymetry survey of positions of a number of adjusting marks fixed at the structural elements. The non-reflection mode of operation of tachymetry survey allows lifting the restrictions for the number of points under observations. The combination of the afore-said factors determines the urgency of the use of the tachymetry as a tool for monitoring the state of the construction project. The subject of the study: the subject of the present research work is the methodology of selection of tachymetry spacing during the deformation monitoring of a construction project. The tachymetry can be carried out both in the mode of focusing on pre-established marks, and in the non-reflection mode through the points on the structure. The disadvantage of the first method is the need of installation of light-reflecting marks, which is not always possible due to some technical and/or aesthetic reasons and may lead to a significant increase in the cost of monitoring. The disadvantage of the second method is a reduced accuracy of the measurements. A wide incremental step may lead to the failure of detection of deformation processes, a narrow step means a considerable increase in the monitoring time and an unjustified rise in the cost of monitoring. Objectives: the purpose of this research work is the optimization of tachymetry spacing, which will reveal all deviations of structural elements from their permanent positions by a value exceeding the accuracy of measurements. Materials and methods: the initial material for the study included the results of geodetic observations carried out at various construction projects, in particular, the tachymetry results. The method of study includes the comparing of the limiting admissible curvature value to the minimum deformation value measured with the tachymeter accuracy. Results: a methodology is suggested for the selection of the tachymetry survey step. On its basis, a formula for the determination of a step value is offered that takes into account the geometry of the structure, the strain capacity of the material and the accuracy of the survey. Conclusions: the obtained results allow us to optimize the number of the observation points during the tachymetry survey and to ensure the detection of all destructive effects associated with structural geometry changes at the construction project. The descriptions of the methodology are recommended for their application in the development of geodetic monitoring programmes.

Underground power grid projects in Hanoi is so urgent that it requires immediate implementation. To synchronously and quickly implement the underground power grid projects, people in charge should not follow the outdated perspectives of just including the power industry, but also need to call for the support and cost sharing responsibility from consumers. This paper aims at approaching the subject both from the producers and consumers’ perspectives to together sharing the cost of putting the power grid underground not only in Hanoi but other metropolitans in Vietnam as well. Field studies (including 104 families) at Hoan Kiem District, Hanoi and CBA method were applied to investigate the willingness to pay (WTP) level of consumers to share the cost with the power industry for the underground power grid projects in Hanoi. The overview of the results shows that cost for the underground power grid in Hoan Kiem District ranging from 30,000 VND/household/month to 46,000VND/household/month. On the other hand, the willingness to pay of a typical household of four people within Hoan Kiem District ranges from 17,000VND/month to 24,000VND/month, with the most favorable method of annual payment within a detailed timeline.

This review is devoted to the monograph by Jan Nedvěd “We do not decline our heads. The events of the year 1968 in Karlovy Vary”. The Karlovy Vary municipal museum coincided its publishing with the fiftieth anniversary of the Prague spring which, considering the way of the presentation, turned the book not only to scientific event but also to the social one. The book describes sociopolitical trends in the region before the year 1968, the development of the reformist movement, the invasion and advance of the armies of the Warsaw Pact countries, and finally the decline of the reformist mood and the beginning of the normalization. Working on his writing, the author deeply studied the materials of the local archive and gathered the unique selection of the photographs depicting the passage of the soviet army through the spa town and the protest actions of its inhabitants. In the meantime, Nedvěd takes undue freedom with scientific terms, and his selection of historiography raises questions. The author bases his research on the Czech papers and scarcely uses the books of Russian origin. He also did not study the subject of the participating of the GDR’s army in the operation Danube, although these troops were concentrated on the borders of Karlovy Vary region as well. Because of this decision, there are no materials from German archives or historiography in the monograph. In general, the work lacks the width of studying its subject, but it definitively accomplishes the task of depicting the Prague spring from the regional perspective.

Subjective Side

From the subject presented in the report it is evident that the pre-trial and the court bodies may, to some extent, be influenced both by the person of the accused and by his competence to participate in the criminal process. In this regard as an expert, the psychologist can offer invaluable assistance. Each expertise would assist all actors involved in the administration of justice on their objective assessment of the offenders, the understanding of their individual protection and the inherent self-justification during procedural actions. The involvement of psychologists in the criminal process is key to establishing the truth in the investigation, because every crime as an act has a subjective side, expressed in the psychic attitude of the perpetrator to the committed act. Establishing these psychological motives is a key point in the criminal process with a view to establishing the truth.Psychological protection stabilizes the personality in the critical conditions of counteraction, related to the elimination of the experiences of tension, anxiety, stress and frustration, leading to maximum mobilization of its resources and at the same time to their overpayment. Thus, the individual who is the subject of the process action is protected against the adverse external influences, but at the cost of a lot of effort and enormous loss of nervous-mental energy, which increases his own vulnerability instead of contributing to its reduction. The appearance and functioning of psychological protection can be significantly impeded by the interaction of the investigator with the accused. Even more complicated is the situation when it breaks the communication contact that may arise in the psychological alienation and self-isolation of the accused due to the desire to protect himself.Protective psychological dominance is a real psychic activity that investigators, investigators, investigators and judges need to take into account in order to effectively deal with their task and to overcome the resistance of the investigated persons and in a time to prove in a lawful and moral way their guilt and participation in the commitment of the crimes.
