Communication as a retarding business-university cooperation factor
Authors: Sieracka Sylwia , Wirkus Marek
Published: September 2021

The goal of the article is to show the possibilities of development (improvements) of the business-university cooperation on from the point of view of enterprises. Authors are looking for a balance enabling agile cooperation between the entities (business needs vs university capabilities). In this article the conditions of the cooperation from the point of view of an enterprise were analyzed. Entrepreneurs point to the passive attitude of the universities regarding cooperation, the lack of openness to the business needs or inquiries and low communication. On the other hand, scientists point out the problem of not getting any offers from entrepreneurs [Trzmielak, Grzegorczyk 2014]. The pandemic caused by the virus SARS-CoV2 has shown the weaknesses of enterprises in many sectors. The most common difficulties are communication problems with stakeholders. Businesses are working very quickly on finding new solutions which will facilitate communication and improve the flow of documentation3 . Works using new technologies have significantly accelerated. The ongoing COVID-19 pandemic has definitely inspired the new generation of crisis communication [Sellnow, Seeger, 2021]. The crisis has forced the creation of new schemes which will be facilitate effective action. The chances of universities cooperating with businesses decreases with the available number of new solutions in the time of the communication crisis. Polish universities definitely miss the marketing orientation. According to businessmen the main barrier is the lack of offers and insufficient information flow. From the business point of view what is interesting is the experience of university employees in assessing the digitalisation of enterprises (Industry 4.0)4 . There is a chance for a development of such cooperation. Time and economic results become important business factors.

Published: September 2021

The role of Islam as a driving force behind greater transparency of sustainability practices (Andri, Suryanto, Ghofur, & Anggraeni, 2020), especially during the digitalization era where all information is easily accessed. Following the Great Recession of 2008, many people sought an antidote to the economy, and Islamic Finance received much attention. Islamic corporate governance is one of the critical areas that has received a lot of attention because it is a tool for steering the economy (Alam Choudhury & Nurul Alam, 2013; A. A. Jan, Lai, & Tahir, 2021; Murphy & Smolarski, 2020; Siswanti, Salim, Sukoharsono, & Aisjah, 2017). Concerning Islamic corporate governance, the questions were answered differently in three layers approaches: 'decision making by consultation (shura'), 'decision making for which end in Allah through the institution of hisba and muhtasib to ensure Shari'a law compliance,' and 'accountability to Allah as human trustee to resources given through religious audit.'

Highly precise multi-cathode pulsed-DC sputtering employing digital processing–application to layer–by–layer synthesis of cubic (Er0.1Y0.9)2Zr2O7 thin film
Authors: Isshiki Hideo , Tanaka Yasuhito , Miyagi Kodai , Kasumi Tomoki , Nakamura Ghent , Saisho Shinichiro
Published: September 2021

A digitally processed DC reactive sputtering (DPDRS) system employing field-programmable gate-array has been developed. In this report, atomically precise pulsed-DC sputtering of a metal oxide compound, cubic (Er0.1Y0.9)2Zr2O7 (c-EYZO), is demonstrated by using DPDRS. An alternating process of pulsed metal sputtering and reactive gas pulsing was applied in order to realize layer-by-layer reactive sputtering. The pulsed metal sputtering separated from the oxidation process results in a stable and high deposition rate of c-EYZO at 1.9 μm h−1, which corresponds to 1.56 nm/cycle. By adjusting the deposition rate to the d-spacing of 0.26 nm corresponding to the (200) diffraction, layer-by-layer synthesis of a highly oriented c-EYZO thin film showing the d-spacing was achieved. X-ray diffraction and photoluminescence measurements indicate drastic improvement of the crystalline properties and the emission properties due to the layer-by-layer synthesis. It is expected that DPDRS enables arbitrarily designed atomically precise deposition of the metal oxide compound synthesis.

The Right of the Employee to an Invention Created in the Process of Labor Relations. (In Accordance With the Georgian - German Patent Legislation)
Authors:   Georgian Technical University, Gurgenidze Miranda , Urtmelidze Tamaz ,   Georgian Technical University
Published: September 2021

Creative activity, which ends with the creation of intellectual property objects, are mostly carried out by individuals employed in various private sectors or scientists working in higher education/research institutions. Therefore, the question who is the owner of the intellectual property object (invention), employee/inventor, whose direct participation with and usage of intellectual labor, the object was created by, or the employer, whose material technical base, experience and the other resources were used to create the invention, does not lose relevance. Georgia belongs to the continental, i.e. Romano-Germanic legal system. Modern Georgian intellectual property law has undergone a very interesting path of development since the restoration of independence. It should be noted that Georgia is the first country from the former Soviet republics to establish a national patent agency in 1992 (12,246). In this article, the authors focus on the basic regulations of Georgian and German patent law that regulate the ownership of an invention created by employees. As it is known, in Georgia the issue is resolved by the „Patent Law“, while in Germany, in addition to the patent law, there is an „Employee Inventions Act“. The scientific article consists of an introduction, a main part and a conclusion. The introduction presents the urgency of the legal problem. The main part, on the one hand, discusses the legal status of inventions created by employees, gives the relationship between patent law and labor law on this issue (on the example of Georgian legislation) and, on the other hand, the authors analyze the German ,,Employee Inventions Act“, which we find a detailed arrangement of an issue of interest to us in. The law is structured in such a way that the balance between the interests of the employee and the employer is maximally maintained, the rule of compensation is provided, a distinction is made between service and free inventions, and ways of resolving disputes between the parties are provided. The legal basis for arbitration is in the foreground. There is also a court of law under the jurisdiction of which these disputes are considered.

Authors:   Georgian Technical University, Katamadze Nato , Berdzenadze Marine ,   Georgian Technical University
Published: September 2021

Problems in the governance process are often caused by incorrect personnel policy and consist of different segments. Mobbing – is a tendency that is still neglected and it is not often mentioned. It is very significant to identify and timely eliminate the causes of mobbing among public servants in Georgian public institutions in order to administer the institution properly, and also to embark effectively on a career development path. Negative interactions between co-workers in public institutions and challenges within the team greatly affect not only the productivity and quality of work, but also the motivation and success of public servants. To make quality improvement and focus on the enhancement in the labor process is the main factor that is spent on aggression and dealing with the controversies within employees. The article depicts the factors that cause mobbing and how this is related to the organizational culture, career advancement and success of employees in the labour teams of Georgian public institutions. Besides, how the current situation impacts on the management process

Published: September 2021

Abstract. The procedures for pre-processing the data of the electronic call management system is implemented in the emergency call center. The purpose of the procedures is to process the raw data entered into the system to obtain statistical data. These procedures, in parallel with data entry, allow data to be converted and stored for later use. Following the introduction of this method, when receiving a statistical request, it is no longer necessary to reperform the procedure, because the data is already stored in the desired form. As a result, the duration of the work to be performed and the required hardware resources are reduced. We analyze the advantages and disadvantages of the data pre-processing method. Also the parameters needed to calculate the average processing time – one of the most important statistical indicators of an electronic system – are given. The paper presents a table corresponding to the example of calculating the average time of call processing. It also shows a formula for calculating the full-time processing time, which is based on the use of simple operations only and does not require much time and hardware resources.
Dynamic Characteristics of a Multimotor Electric Motor Multichannel Control System, Taking Into Account the Elasticities of Mechanical Transmitters
Authors:   Georgian Technical University, Beradze Nana , Khachapuridze Oleg ,   Georgian Technical University
Published: September 2021

The study of the dynamic characteristics of two- and three-engine thyristor electric motors with constant current, in the case of a multi-motor control system, taking into account the elasticity of mechanical shafts are reviewed in this article. Such multimotor control systems are widely used in metallurgical production. For example, in sheet rolling mills, where in the mechanical part there are moments of significant dynamic curvature. The paper also reviews the functional and structural schemes of a cohesive multi-engine system. In the case of a multi-motor touring electric motor system, the structural scheme of a two-engine drive was studied in order to determine the correct load distribution. The study was conducted using a computer program - MATALAB using 150 kW and 300 kW engines. A Kalman filter-like observation device is used to quench the binding oscillations generated in the system. The quality indicators obtained from the transient mode studies are close to the optimal parameters, so the considered system is suitable for multi-motor rolling mills.

Published: September 2021

The optimal mode of operation of an electric car depends to some extent on the technical condition of its mechanical parts. Under operating conditions, unbalanced masses, eccentrically located in relation to the axis of rotation, may occur in the rotor of an electric car, which, in turn, will lead to premature output of machine bearings and, as a consequence, to a deterioration in dynamic characteristics. In this regard, the paper presents a method of compensating for the impact of unbalanced masses of the rotor, during which the analysis of the relationship between the amplitude of the oscillation and the angle of attachment of the compensating load is performed according to the measurement results. One of the downsides of this method is the multiple launches of the electric car and the use of concepts such as balancing sensitivity, corrective mass and more. A relatively flexible method of dynamic balancing of an electric car is shown, based on the measurement of the vibration speed amplitude and vibration phase of the electric car. Relevant oscillograms and analytical images are given, the analysis of which achieves complete suppression of electric vehicle vibration by attaching additional compensating load to the rotor.

WOMEN & EQUALITY IN WESTERN ODISHA: THE GROUND REALITY.
Authors: Panda Binita
Published: September 2021

The 21 century is well-known for its advancement and development in every aspect.Similarly it cannot be ignored that st
everywhere one strong belief has been established that women are equal with men. No doubt women are being
empowered and have proven themselves in the higher position in different sectors. There are provisions for the
promotion and protection of women's rights in UDHR, several international covenants, Indian constitution, and in the
various schemes enunciated by the state government at the local or grass root level too. But in real world, are women
actually treated equally with men in every field? Whether the legal provisions are been actually practiced? Are they
leading a free and independent life as their counterparts? Are they enjoying equality with their men folk? Are these legal
provisions really helping them? All the above questions remained unanswered. In this regard this paper analyses the
provisions guaranteed by the Indian constitution providing equality both for men and women i.e.Right to equality with
its ground reality.To answer the above questions it discusses the current status and position of women in western Odisha.

Published: September 2021

We report the design,
fabrication and quantitative performance analysis of a low-cost, flexible
carbon nanotube (CNT) network-based deoxyribonucleic acid (DNA) sensor. These
sensors comprise an array of ink-jet printed silver (Ag) electrodes on a
transparent polyethylene terephthalate (PET) flexible substrate, where a CNT
network acts as a sensing layer. The DNA hybridization is studied by
immobilizing single-stranded DNA (ssDNA) probes on the CNT surface; these
probes recognize their complementary DNA target. Further, we have carried out a
quantitative performance analysis of the flexible CNT biosensors using the
analytic hierarchy process (AHP). We have identified various influencing
factors and sub-factors (performance indicators), and quantified the
performance of the flexible CNT biosensors in different measured states (before
bending, during bending and after bending). Additionally, the noise and other
external factors contributing to the measured real signal have been
quantified. The interpretation of the
overall outcome will enable the improvement of the performance of flexible
biosensors fabricated through large-scale manufacturing for possible
commercialization.

Authors: Myachin Nikolay , Donchevskaia Ludmila
Published: September 2021

The dynamics of crime depend on many factors, among which unemployment occupies a special place. This is due to the fact that declining real incomes and increased competition in the labor market create incentives to engage in illegal activities. Most foreign studies conclude that unemployment predominantly affects the level of property crime, while the dynamics of general crime does not depend on the state of the labor market. This article aims to analyze the mutual influence of unemployment and various types of crime in the Russian context. Using official statistics and analysis of panel data, the authors conclude that unemployment has a significant impact on the number of economic crimes in Russia.

Published: September 2021

Pets have conquered the daily lives of families worldwide and because they have a close relationship with humans, they can transmit mycotic zoonoses such as dermatophytosis, malassezioses and candidosis. Studies show that fungi with pathogenic potential have already been granted in clipping instruments and bath articles in veterinary clinics and in Pet Shops. In the absence of data in the city of Sinop - MT, this study aimed to isolate fungi with pathogenic potential in clipping instruments used in the routine of Pet Shops and to identify etiological agents capable of causing mycotic zoonoses. Samples were carried out in 18 clipping instruments, without cleaning, from 10 Pet Shops (A, B, C, D, E, F, G, H, I, J) in the city of Sinop - MT with swabs and sterile carpets square and then seeded in Sabouraud agar with 0.05% chloramphenicol and mycobiotic agar, incubated at room temperature (25°C) for 30 - 45 days. The dermatophytes and non-dermatophyte filamentous fungi were identified using the microculture technique and urease test and as yeasts using a urease test, zymogram, auxanogram, germ tube and corn meal agar with polysorbate 80. Of the samples from 18 clipping instruments, 15 were positive for at least one fungal genus. The yeast that showed a high prevalence of isolation in clipping instruments from the studied Pet Shops (B, C, D, E, H and J) was Malassezia pachydermatis (86.7%), followed by the genus Candida spp. (C and D; 26.7%), filamentous fungi of the genus Aspergillus spp. (A; 13.3%), Microsporum canis (B; 13.3%) and Trichosporon spp. (J, 6.7%). Our results demonstrate that Pet Shops treat a large number of animals daily in a single environment, which may amplify the risk of spreading zoonoses, as an asymptomatic or sick carrier animal can potentially transmit the microorganism to other animals inside the store and thus to a large number of new pet owners. There is a need to reinforce the commercial requirements specialized in bathing and grooming in the city of Sinop - MT on the good practices of cleaning and disinfection of the elements used and the environment, eliminating or eliminating the risk of contracting mycotic zoonoses.

Hansen´s disease is an infectious and contagious disease with high morbidity indexes. It is a public health issue with patients´ negative life quality (LQ). Current study determines the life quality-based clinical factors of patients with Hansen´s Disease. Sixty-three patients with Hansen´s Disease participated in the research. They were attended to in a Reference Service Centre. World Health Organization Quality of Life Bref (WHOQOL- BREF) was applied to evaluate their LQ and linear regression was employed to assess the association between clinical variables and WHOQOL-BREF domains. Statistical analysis of mean LQ scores showed a significant difference in the physical domains for variables comorbidity (p= 0.043) and intake of medicines (p=0.007). After multiple linear regression, no other clinical variables under analysis proved to be associated with LQ. Patients with self-reported comorbidity and those who continually use medicine have lower LQ averages within the physical domain. Activities that contribute towards the promotion of integral health assistance and for the improvement of LQ for patients with Hansen´s Disease should be enhanced.

Получены значения динамической вязкости битумного вяжущего с добавками низкомолекулярного полиэтилена в температурном интервале 60…160 °С. При введении полимерных добавок в дорожный битум вязкость битума повышается. Наиболее высокие значения динамической вязкости наблюдаются у полимерной добавки Вискодор - ПВ1, это ярко выражено при расходе 4 % добавки от массы битума и при температурах ниже 130°С. Добавка неокисленного низкомолекулярного полиэтилена Honeyvell Titan 7205 увеличивает вязкость в большей степени, чем добавка окисленного полиэтилена Honeyvell Titan 7686. Определены допустимые технологические температуры асфальтобетонных смесей с полимерными добавками на этапах структурообразования асфальтобетона.

We obtained the values of the dynamic viscosity of bitumen binder with additives of polyethylene with low molecular weight in the temperature range of 60…160 °C. When polymer additives are introduced into road bitumen, the viscosity of bitumen increases. The highest values of dynamic viscosity are observed for the polymer additive Viskodor - PV1, this is clearly pronounced at the consumption of 4 % of the additive based on the mass of bitumen and at temperatures below 130 °С. The additive of unoxidized low molecular weight polyethylene Honeyvell Titan 7205 increases the viscosity to a greater extent than the additive of oxidized polyethylene Honeyvell Titan 7686. We determined as well the permissible technological temperatures of asphalt concrete mixtures with polymer additives at the stages of structure formation of asphalt concrete.

Рассмотрена проблема сокращения затрат при потреблении электрической энергии оборудованием центральной котельной средней мощности. Перспективным направлением в решении этой задачи является использование альтернативного источника электроэнергии в виде газопрошневой установки. Теплогенерирующие установки для централизованного теплоснабжения были рассчитаны с учетом минимального потребления электроэнергии и достижения надежности. Проведен анализ потребления электроэнергии оборудованием котельной установленной мощностью 4,7 МВт. Определены технические характеристики газопоршневой установки, выбранной в качестве нового источника электроэнергии. Проведены технико-экономические расчеты стоимости производства собственного электричества для котельной. Применение собственного источника электроэнергии позволяет снизить стоимость электроэнергии в сравнении с покупкой от центральных электросетей. Сделан вывод о том, что применение собственного альтернативного источника электроэнергии для котельной - это выгодное вложение для снижения финансовой нагрузки на теплоснабжающую организацию и для снижения стоимости тарифа на тепловую энергию.

The problem of reducing cost of electricity consumption by the equipment of the central boiler house of medium capacity is considered. A promising direction in solving this problem is the use of an alternative source of electricity in the form of a gas-piston installation. Heat generating plants for district heating were designed taking into account the minimum electricity consumption and achieving reliability. We carried out the analysis of electricity consumption by the boiler house equipment with an installed capacity of 4.7 MW. The technical characteristics of the gas-piston plant selected as a new source of electricity were determined. As well we carried out technical and economic calculations of the cost of producing own electricity for the boiler house. The use of its own power source allows one to reduce the cost of electricity in comparison with the purchase from the central power grid. It is concluded that the use of its own alternative source of electricity for the boiler house is a profitable investment to reduce the financial burden on the heat supply organization and to reduce the cost of the heat energy tariff.

Low power is an essential requirement for suitable multimedia devices, image compression techniques utilizing several signal processing architectures and algorithms. In numerous multimedia applications, human beings are able to congregate practical information from somewhat erroneous outputs. Therefore, exact outputs are not necessary to produce. In Digital signal processing system, adders play a vital role as an arithmetic module in fixing the power and area utilization of the system. The trade off parameters such as area, time and power utilization also the fault tolerance environment of few applications have employed as a base for the adverse development and use of approximate adders. In this paper, various types of existing adders, approximate adders are analyzed based on the area, delay and power consumption. Also an approximate, high speed and power efficient adder is proposed which yields the better performance than the existing adders. It can be used in various image processing applications, data mining and where the accurate outputs are not needed. The existing and proposed approximate adders are simulated by using Xilinx ISE for time and area utilization. Power simulation has been done by using Microwind Software.

This research aims to study the surface characteristics of low carbon steel JIS G3101 SS400 processed by sandblasting using steel grit G25. The sandblasting process is conducted at a fixed nozzle pressure of 5 bar and pressure angle of 90o, and varying nozzle-to-surface distances at 15, 25, and 30 cm, and blasting durations of 25, 45, and 120 s. Surface characterization is firstly carried out by conducting observation on the surface’s morphology by SEM and chemical composition by EDS. Subsequently, visual inspection and measurement on surface roughness and hardness profile identification by Rockwell and micro-Vickers hardness tests are conducted. A paint thickness test using ASTM D7091 was undertaken to observe the surface characteristics related to the coating process. Based on the result, SEM found valleys, granules, micro-cracks, and grits embedded on the surface. The visual inspection shows the roughness is within the range of Sa2 - Sa3 of ISO 8501 with values are Ra 18.1 and Ra 21.4 µm. The hardened layer exhibits a maximum hardness value of 332 HV and a depth of more than 50 µm by sandblasting parameters of 15 cm distance and 120 s duration. Both roughness and hardness profiles are confirmed, increasing with closer nozzle-to-surface distance and longer blast duration. It is concluded that sandblasting using steel grit G25 is effective in improving the mechanical strength and surface hardness of low carbon steel SS400. These mechanical properties are essential in the paint coating of machinery applications such as pump, tank, ship, and pipeline.
