Organizational and economic mechanism for increasing the competitive-sustainable of an industrial enterprise
Authors: Tikhonov A.I.
Published: June 2020

The article considers the need for industrial enterprises to increase their own competitiveness, as well as the formation of certain competitive advantages. The author identifies the main groups of indicators used in the management of the competitiveness of an industrial enterprise. The classification of methods for managing the competitiveness of an industrial enterprise is given. The factors of increasing the competitiveness of an industrial enterprise are determined. An algorithm for managing the competitiveness of an industrial enterprise has been developed, which includes the following steps: determining strategic goals; identification and analysis of factors affecting the competitiveness of the enterprise; assessment of the influence of factors on the level of competitiveness for each management object; a grouping of methods and measures to increase competitiveness; development and implementation of the organizational and economic mechanism to increase the competitiveness of the enterprise; assessment of results and analysis of the effectiveness of the proposed activities; managerial decision making. The author’s interpretation of the concept of «organizational and economic mechanism» is justified with the aim of increasing the efficiency of competitive stability of an industrial enterprise. The author notes the fact that conducting business to increase profits ignores the criteria for increasing the cost of equity, which are necessary for the further development of an industrial enterprise in a competitive environment. Based on the analysis of scientific literature and taking into account the specifics of the industrial enterprise, a three-component structure of the organizational and economic mechanism for managing its increased competitiveness is modeled.
Ética como jogo de cena
Authors: Araújo Pedro Felipe M. de , Baptista Luis Antonio dos Santos
Published: June 2020

Tendo como foco o documentário Jogo de cena,de Eduardo Coutinho, o artigo objetiva propor questionamentos acerca das posturas dominantes de interpretação sobre o sujeito de uma história narrada. Deseja também apresentar outras possibilidades de sentido do que seja a alteridade no convívio com a diferença. O filme, ao situar a cena da fala como um jogo aberto, se desloca da busca de uma estável verdade sobre si que o outro revelaria. Esse deslocamento desprivatiza a esfera do íntimo, possibilitando a produção de uma obra aberta, que torna inoperanteuma leitura única. Inspirado nas contribuições de Walter Benjamin, entre outros autores, pretende-se ressaltar a aposta de uma ética que promova percepções de mundo que não se esgotem na tentativa de classificar uma narrativa no âmbito identitário ou privatizante da subjetividade. A ética como jogo político onde histórias recusam a conclusividade do fim.
Heterotopias e trajetividades: lugares para as diferenças nas subjetividades nômades
Authors: Carvalho Alexandre Filordi de
Published: June 2020

A partir de duas experiências cinematográficas, Omar e  The giver (O doador de memória) como agenciamentos de signos da arte, busca-se, ao longo do texto, explorar a ideia de que heterotopias e trajetividades são noções importantes para se pensarem as diferenças no sentido de experiências de subjetividades nômades. Para tanto, é preciso combater a máquina de produção de subjetividades sedentárias. Dessa maneira, em um primeiro momento, desde uma hipótese proustiana, intenta-se entender o que são experiências com as heterotopias e as trajetividades, sobretudo a partir do filme Omar. Em segundo lugar, a partir de uma questão extraída do filme The giver, explora-se como o campo problematizador das diferenças pode ser afirmado entre a confrontação da máquina de produção de subjetividade sedentária e a máquina de produção de subjetividade nômade.

Published: June 2020

Abstract— BED for measuring EBV and CO are the tools used to monitor the condition of preoperative patients. The Estimation Blood Volume (EBV) is a calculation to determine the approximate volume of blood in the human body and CO is the amount of blood volume pumped by the heart per minute the calculation of EBV used uses weight, height and gender. CO calculations utilize BPM multiplied by standard Stroke Volume. In this section the author discusses oxygen saturation in the blood using different wavelengths of red LED light and infrared captured by the photodiode. The author also discusses BPM to monitor minute heart rates. The design of this measuring instrument uses MAX30100 sensor, Arduino Mega , Arduino Nano and TFT LCD. Data from the MAX30100 sensor enters the Arduino minimum system, then is processed to produce a percentage of SpO2 values ​​which are then displayed on the TFT LCD. In the module, the data displayed can be stored and displayed again so that patient data can be traced. Testing is done by comparing the module with a standard measuring instrument that produces the biggest error of 2.80% on BPM and 0.95% on SpO2.

Published: June 2020

pH Meter is a device used to express the level of acidity or basicity possessed by a substance or solution. Normal pH has a value of 7 while the pH value> 7 indicates that the substance has alkaline properties while the pH value <7 indicates acidic properties. pH 0 shows a high degree of acidity, and pH 14 shows the highest degree of alkalinity. pH Meter reads the pH and temperature values ​​in a sample. The author uses glass electrodes as a pH sensor, DS18B20 as a temperature sensor and LCD to make pH and temperature values. This module is equipped with an internal calibration that is used to set the module to read the pH value properly and correctly using a pH buffer and equipped with internal storage and this module facilitates battery usage. Based on pH measurements on the module the error value in buffer 4 calibration is 5.39%, in buffer 7 is 1.76%, in buffer 10 is 1.04%. The highest error value in the measurement sample is 3.54% and the lowest error value is 0.03%. The temperature of the sample is very influential on the reading of the pH value because the higher the temperature the pH value also increases even though it is not so significant.

Wyrok Trybunału Sprawiedliwości Unii Europejskiej z perspektywy kognitywnej teorii prototypu. Studium przypadku
Authors: Zeifert Mateusz
Published: June 2020

Interpretative doubts in the application of law are usually born of discrepancies between the statutory language and the non-linguistic reality. Therefore, they pose the problem of categorization. The theory of law and legal practice have for centuries been dominated by the classical theory of categorization, according to which conceptual categories can be described by a set of sufficient and necessary features. In the 1970s, an American researcher Eleanor Rosch conducted a series of psychological experiments that led her to question the classical theory and lay the foundations for an alternative one, known as the prototype theory. According to this approach, conceptual categories are organized around the most typical exemplars (prototypes), and membership of a category is measured by similarity to the prototype. Some of the consequences of such view are that category membership is a gradable feature and that the borderlines of categories are fuzzy. The article presents an outline of the prototype theory in the version used in cognitive linguistics. Its usefulness for the theory and practice of statutory interpretation is tested on the basis of the judgment of the Court of Justice of the European Union regarding the concept of beer. In this judgment, the CJEU refused to define the concept of beer by setting requirements as to its raw material composition and ruled that beer is a product that has organoleptic characteristics of beer. This definition on the basis of classical theory appears to be tautological, however, it finds theoretical justification in the prototype theory. In conclusions, the author indicates research problems that must be taken up in order for the prototype theory to be reliably used in jurisprudence.
Rola wartości w interpretacji prawa. Ujęcie normatywne
Authors: Bogucki Olgierd
Published: June 2020

The article presents and analyses a certain theory of values and their role in legal interpretation. The article calls it a ‘componential’ theory of values. According to the theory, values in law create structures based on global assessments: comprehensive axiological judgements that consider all the relevant values and degrees of their realization. The basic theorem of the theory is the theorem on isomorphy between the global assessment and the content of the legal norm. This ‘componential’ theory is the basis of the normative model of legal interpretation. According to this model, the interpreter should reconstruct the global assessment and choose the one possible result of interpretation – the one norm of conduct – which will be the most consistent with this judgement. In order to reconstruct the aforementioned global assessment, the interpreter should consider the legal text, case law and legal literature, legislative materials and interpretative presumption.

The article reconstructs the philosophical presumptions behind the aforementioned theory and model. The article points out that the fundamental value behind the normative model is the intersubjectivity of legal interpretation as an element of the rule of law. The article also indicates that the theory and model described above are based on legal positivism, but with significant connections with legal hermeneutics, Dworkin’s theory of law, and argumentative approaches to law. In addition, the theory seems to presume weak commensurability of values.

AN ANALYTICAL INVESTIGATION OF A BUILDING HAVING SOFT STOREY IRREGULARITY STRENGTHENED WITH CONCENTRICALLY STEEL BRACES
Authors: ÜNAL Alptuğ
Published: June 2020

When buildings that were damaged and destroyed in major earthquakes in previous years are examined, it is seen that these buildings have several structural defects. One of these defects is that soft storey irregularity is not predicted in reinforced concrete buildings. For this reason, many buildings collapsed because of the major earthquakes, resulting in loss of life and property. Buildings stocks in earthquake zones must be inspected and buildings with the soft storey irregularity must be strengthened immediately. Also, strengthening methods are required to be quick and effective, and aesthetics of structures should not be disturbed. In this study, a 10-storey building with the soft storey irregularity is discussed. The building is strengthened with five different types of Steel Braces in various earthquake regulations in the world. The strengthening was conducted with a nonlinear analysis program and results were evaluated.

Published: June 2020

Kinshasa, capital of Democratic Republic of the Congo (DR Congo), is facing serious noise problems caused by the expansion of transportation and the increase of traffic volume without any regulation or policy introduced. This social survey conducted in September 2017, is the first survey ever performed on road traffic noise in Kinshasa. Four sites along major roads were selected. Questionnaire survey was carried out by face to face interview and 235 samples were collected. A 24-hour noise measurement was conducted at a representative point of each road and the noise indices such as Lden were calculated. The Lden of the four sites were from 73 to 79 dB. The percentages of highly annoyed and highly sleep disturbed were from 30% to 41% and 38% to 52%, respectively. The higher percentages were observed in sites with the higher noise level. A logistic regression analyses were applied to plot the dose-response relationship for general annoyance. The result was close to EU curve and higher than that in Vietnam.

Published: June 2020

The paper summarizes the findings of experimental studies on animals and literature data to show the characteristics of the lungs exposure to low-frequency acoustic vibrations. Experimental studies were performed on laboratory animals of different species (mice, rats, rabbits, dogs) exposed to low-frequency acoustic vibrations on the test bench set for several months. To assess lung injury, broncho-alveolar lavage, surfactant, biologically active substances in the tissues of the lung, extracellular low-molecular blood DNA were investigated, computerized tomography and postmortem methods were used. It has been established that that prolonged action of high-intensity low-frequency acoustic waves leads to structural damage to the lung parenchyma, lung airiness disorder, bronchi patency and metabolic functions of the lungs. The revealed disorders can serve as a structural basis for the development of such lung diseases as chronic non-specific lung disease of the obstructive bronchitis and/or focal emphysema type. Morphological and functional parameters of the lungs can be considered as criteria for the harmful effect of low-frequency acoustic vibrations on the human body and animals. The obtained experimental data allow us to formulate the concept of the mechanisms of the harmful effect of this physical factor on the lungs. The respiratory system is a critical organ in relation to low-frequency acoustic vibrations. It is necessary to correct the ideas of professional ‘noise’ pathology with regard to the damage to the hearing organ only in the form of neurosensory hearing loss. As it can be seen from the presented findings, the nature of disorders in the body is determined by the noise parameters (intensity, duration and spectral composition).

Published: June 2020

The creation of the high capacity transport vehicles where vibro active parts are increasingly used that inevitably leads to an increase in vibration and noise levels and it adversely affects the locomotive crews as well as pollute acoustically while operating in a residential area. This problem is most relevant for rolling stock. The recommendations of the European Union are aimed at reducing the noise of the railway transport directly in its places of origin as rolling stock and track structures. It should be noted that the noise decline should not be limited to measures of the indirect protection: the construction of the noise protection walls and the use of the noise protection windows in buildings located close to the railway track. First of all, in the opinion of the European Union, it is necessary to implement measures to suppress noise in the sources themselves.
For solving the problem, the research has been carried out by different experts from foreign countries. However, the process of the formation vibro acoustic characteristics is not well understood.
The diesel locomotives and locomotives are intensively exploited. It should be considered that one of the main sources of the air and structural noise component is an internal combustion engine for these machines, the noise and vibration levels which are practically impossible to reduce in the industrial conditions. Therefore, on the basis of the theoretical and experimental studies, the practical recommendations have been developed for achieving sanitary noise standards by ensuring the required sound absorption and sound insulation values.
