The paper considers contradictions which arise after entering amendments in 2014 into article 242 of the Criminal Procedural Code of Ukraine, in which an obligatory appointment of psychological examination for the determination of moral harm amount in criminal trial is allocated. The thought on inexpediency of appointment of the person moral sufferings examination within the limits of criminal proceedings on the basis ofsuch positions is subtatiated: 1) before pronouncement of a court sentence on criminal proceedings a person’s guilt is not proved, in this case forensic psychological examination will be based on not proved premise - possibility of guilt which conflicts to an innocence presumption according to the Criminal Code of Ukraine. The expert conclusion is one of procedural sources ofproofs. Carrying out forensic psychological examination of moral harm within criminal proceedings, the expert, being based on the inadmissible assumption of guilty, creates the proof; 2) if the question of moral sufferings presence is considered within criminal proceedings, the fact of absence of the claimantfault has to be established by the court along with definition of the respondent fault degree; 3) pronouncement of a court sentence with definition of the parties guilty degree is an important point for definitive qualitative and quantitative formalizing moral sufferings. At the stage «before a sentence» the psychological trauma has not been yet led to the fullforming ofmoral sufferings, therefore during carrying out psychological research on the materials of criminal proceedings the amount of compensation should be defined only as "a preliminary"; 4) for the determination of the depth and heaviness of the person’s sufferings a psychologist needs to conduct a research only in 1 yearfrom the moment of injuring events (the person should go through stages of distress after losing close relative, to be treated and feel consequences at health damage).

One of the most important characteristics of a fractal is its dimensionality. In general, there are several options for mathematical definition of this value, but usually under the object dimensionality is understood the degree of space filling by it. It is necessary to distinguish the dimensionality of space and the dimension of multitude. Segment, square and cube are objects with dimensionality 1, 2 and 3, which can be in respective spaces: on a straight line, plane or in a 3D space. Fractals can have a fractional dimensionality. By definition, proposed by Bernois Mandelbrot, this fractional dimensionality should be less than the fractal’s topological dimension. Abram Samoilovich Bezikovich (1891–1970) was the author of first mathematical conclusions based on Felix Hausdorff (1868–1942) arguments and allowing determine the fractional dimensionality of multitudes. Bezikovich – Hausdorff dimensionality is determined through the multitude covering by unity elements. In practice, it is more convenient to use Minkowsky dimensionality for determining the fractional dimensionalities of fractals. There are also numerical methods for Minkowsky dimensionality calculation. In this study various approaches for fractional dimensionality determining are tested, dimensionalities of new fractals are defined. A broader view on the concept of dimensionality is proposed, its dependence on fractal parameters and interpretation of fractal sets’ structure are determined. An attempt for generalization of experimental dependences and determination of general regularities for fractals structure influence on their dimensionality is realized. For visualization of three-dimensional geometrical constructions, and plain evidence of empirical hypotheses were used computer models developed in the software for three-dimensional modeling (COMPASS, Inventor and SolidWorks), calculations were carried out in mathematical packages such as Wolfram Mathematica.

Galvanizing technological operations include the processes of cleaning the surfaces of parts from burrs, burrs, bumps and scale, corrosion products, rounding of sharp edges, separation of parts from castings, as well as processes to improve the quality of product surfaces: grinding or polishing. These technological operations are implemented using different types of equipment: vibrating, rotary and spindle machines, rotating drums, etc. The most promising are considered to be machines with complex spatial movement of working tanks. Analytical researches of definition of dynamic moment of resistance of a driving shaft of the shredding machine on the basis of laws of movement of loose mass in the middle of working capacity are carried out. The positions of the moving parts of the machine and the bulk array in the middle of the tank, which correspond to the maximum dynamic component of the moment of resistance on the drive shaft created by the bulk array loaded to the working tank. An expression is obtained to calculate the value of the dynamic component of the moment of resistance on the drive shaft of the machine, created by the bulk array loaded to the working tank. The obtained research results can be used by the relevant machine-building enterprises at the stage of designing galvanizing types of equipment with tanks performing complex spatial motion.

This article presents a historical overview of the emergence of tax monitoring in the Russian Federation, as well as the analysis of its peculiarities within the context of trends of global taxation practice. Modern nations apply new approaches to tax administration, but commonly emerging and practically established ideas do not receive due scientific research. The object of this research is the process of digitalization of tax administration based on Russian and foreign experience. The subject of this research is the theoretical aspects of tax monitoring, as well as historical analysis of the emergence of a new format of interaction between tax administration and taxpayers in Russia and global practice. The goal of this work is to determine the role and importance of tax monitoring within taxation system of the Russian Federation, as well definition of tax monitoring as the means of digitalization of tax administration. The scientific novelty of this work consists in the comprehensive research of implementation of tax monitoring from the moment of its emergence in the global practice of taxation and determination of its essential features, which allowed concluding on incorrectness of legislator’s definition of tax monitoring as a form of tax control, and call for legislative definition of the concept of “tax administration”, as well as amending the Taxation Code of the Russian Federation for clarification of the status of taxpayers, who transitioned to the digital model of tax administration. The results of this research can be used in development of amendments to the legislation and criteria for assessing efficiency of tax monitoring.

Legal Consequences

This chapter discusses the determination of refugee status. The legal consequences that flow from the formal definition of refugee status are necessarily predicated upon determination by some or other authority that the individual or group in question satisfies the relevant legal criteria. In principle, a person becomes a refugee at the moment when he or she satisfies the definition, so that determination of status is declaratory, rather than constitutive. However, while the question of whether an individual is a refugee may be a matter of fact, whether or not he or she is a refugee within the 1951 Convention, and benefits from refugee status, is a matter of law. Problems arise where States decline to determine refugee status, or where States and the Office of the United Nations High Commissioner for Refugees (UNHCR) reach different determinations.

Un modelo para visualizar objetos en 4D con el Mathematica A model to visualize objects in 4D with Mathematica Ricardo Velezmoro y Robert Ipanaqué Universidad Nacional de Piura, Urb. Miraflores s/n, Castilla, Piura, Perú.  DOI: https://doi.org/10.33017/RevECIPeru2014.0008/ Resumen Una variedad de técnicas de gráficos por computadora han permitido la visualización de objetos, que existen en dimensiones más altas, en una pantalla 2D. En este artículo se propone un nuevo modelo a partir de la extensión de una técnica útil en la visualización de objetos en 3D en una pantalla 2D para realizar algo similar con objetos en 4D. Dicha técnica se basa en la definición de una inmersión, en primera instancia, del espacio tridimensional en el espacio bidimensional que luego se toma como referencia para definir otra inmersión, que constituye el modelo propuesto en este artículo, del espacio tetra dimensional en el espacio tridimensional. En teoría la visualización de objetos en 4D en una pantalla 2D se consigue mediante la composición de las dos inmersiones mencionadas, pero en la práctica se aprovechan los comandos incorporados en el sistema de cálculo simbólico Mathematica para tal fin. Descriptores: objetos 4D, modelo, inmersión Abstract A variety of computer graphics techniques have enabled the display of objects, which exist in higher dimensions, on a 2D screen. In this paper a new model from the extension of a technique useful in visualizing 3D objects on a 2D screen to make something similar with 4D objects is proposed. This technique is based on the definition of a immersion, in the first instance, from the three-dimensional space in two-dimensional space which is then taken as a reference to define another immersion, which is the model proposed in this paper, from the fourdimensional space in three dimensional space. Theoretically the visualization of objects in 4D on a 2D screen is achieved by the composition of the two immersions mentioned, but in practice the incorporated commands into the computer algebra system Mathematica for this purpose are utilized. Keywords: objects 4D, model, immersion.

Twitter is one of the social medias that are widely used at the moment. Tweet conversations can be classified according to their sentiments. The existence of sarcasm contained in a tweet sometimes causes incorrect determination of the tweet’s sentiment because sarcasm is difficult to analyze automatically, even by humans. Hence, sarcasm detection needs to be conducted, which is expected to improve the results of sentiment analysis. The effect of sarcasm detection on sentiment analysis can be seen in terms of accuracy, precision and recall. In this paper, detection of sarcasm is applied to Indonesian tweets. The feature extraction of sarcasm detection uses unigram and 4 Boazizi feature sets which consist of sentiment-relate features, punctuation-relate features, lexical and syntactic features, and top word features. Detection of sarcasm uses the Random Forest algorithm. The feature extraction of sentiment analysis uses TF-IDF, while the classification uses Naïve Bayes algorithm. The evaluation shows that sentiment analysis with sarcasm detection improves the  accuracy of sentiment analysis about 5.49%. The accuracy of the model is 80.4%, while the precision is 83.2%, and the recall is 91.3%.

This essay reviews recent controversy in the determination of death, with particular attention to the definition and moment of death. Definitions of death have evolved from the intuitive to the pathophysiologic and the medicolegal. Many United States jurisdictions have codified the definition of death relying on guidance from the Uniform Determination of Death Act (UDDA). Flaws in the structure of the UDDA have led to misunderstanding of the physiologic nature of death and methods for the determination of death, resulting in a bifurcated concept of death as either circulatory/respiratory or neurologic. The practice of organ donation after circulatory determination of death (DCDD) raises a number of ethical questions, most prominently revolving around the moment of death and manifested as an expedited time to determination of death, a departure from the unitary concept of death, a violation of the dead donor rule, and a challenge to the standard of irreversibility. Attempts to redefine the determination of death from an irreversibility standard to a permanence standard have significant impact on the social contract upon which deceased donor organ transplantation rests, and must entail broad societal examination. The determination of death is best reached by a clear, strict, and uniform irreversibility standard. In deceased donor organ transplantation, the interests of the donor as a person are paramount, and no interest of organ recipients or of the greater society can justify negation of the rights and bodily integrity of the person who is a donor, nor conversion of the altruism of giving into the calculus of taking.

A refined definition of the concept at the moment of force is obtained. Its application eliminates the contradiction existing in the Іnternational System of Units (SI). It is established that the unit of the force moment is N·m/rad, and the unit of the coefficient, which connects of force and torque, is m/rad. It is shown that the concept of “shoulder strength“ has no relation to the determination of the moment of force. Keywords: Іnternational System of Units (SI), energy, work, force moment, dimensional formula.

Aim. Analysis of some controversial provisions of Article (Art.) 66 Determination of the Moment of Death of a Person and of Termination of Resuscitation Activities of Federal law On Fundamental Healthcare Principles in the Russian Federation of November 21, 2011 №323-FL (FL 323) directly concerning the issue of death of a person, and justification of making amendments to the title and text of the above mentioned norm. Due to the absence of definition of the concept of death in FL 323, the author presents his own definition of death of a person. The used term the moment of death of a person as a determinant/indicator of the occurrence of death seems to be erroneous. This term cannot be extended to the fact of biological death. Under FL 323, death of the brain is considered to be equivalent to death of a person and today is inextricably linked with organ transplantation. However, in reality it is not so, and in this sense it is a typical juridical fiction that justifies legal removal of organs from living patients. Amendments to the title and wording of Article 66 FL 323 are proposed.
