Authors: Fisunenko Nadya , Sidorov Oleksandr
Published: July 2021

The article is devoted to the study of the influence of environmental factors on the economic security of construction enterprises. The factors of the influence of the external environment on construction enterprises have been analyzed, as a result, it has been established that they are divided into a macro-environment and a micro-environment, direct (direct) impact and indirect (indirect) action.
It is proposed to refer to the main factors of the impact of the external environment on the economic security of construction enterprises indicators of direct impact, which include: suppliers, competitors, consumers, the state, trade union committees, marketing intermediaries and the contact audience of the enterprise.
The content of the factors of direct influence, suppliers, on the activities of the enterprise, namely, the dependence of the construction organization on the quality, quantity and timeliness of the materials or services provided, necessary for its, functioning, is disclosed. The influence of the consumer on the activities of a construction company is determined, which is carried out by signing contracts, paying for work or services under concluded contracts.
The features of the influence of competitors are established, taking into account such parameters as: the number of firms specializing in the production of similar types of work (services), the growth rate of the industry, the degree of concentration of the industry, the price structure in the industry, the level of profit margins. The influence of the state and the trade union committee and found that the main influence of the state and its organs on the financial position of the company is realized through the establishment of the level of taxes and the size of subsidies, capital investments, and the contact with the union, in fact, the company provides its workforce. The impact of which in the future will help assess the associated threats or benefits to the economic security of construction enterprises.
It is also proposed to include as external factors of indirect (indirect) impact on economic security: political, socio-cultural, scientific and technological progress, environmental safety, demographic and geographical factors. These factors are more complex and unpredictable, variable and uncertain. It is generally accepted that indirect impact factors do not significantly affect the activities of enterprises, but their impact in the future will help to assess the associated threats or benefits to the economic security of construction enterprises.

OUTSOURCING MEANS AT AGRICULTURAL BUSINESS ENTERPRISES: EXPERIENCE AND PROSPECTS OF USE
Authors: Koverha Serhii , Dziuba Mykola
Published: July 2021

The article considers the development of outsourcing relations in the world, the role of outsourcing in the development of the world economy.
There are some researches on this issue that describe certain aspects of the functioning of organizations that use outsourcing in their activities, which, however, without considering the industry specifics of using outsourcing. In particular, this applies to the theoretical and practical use of outsourcing in the agricultural business.
Taking into account the dynamic of outsourcing development, its research requires constant scientific exploring, updating knowledge in this area, comprehensive analysis, generalization of modern outsourcing practices, and formulation of the precise scientific and practical recommendations.
Outsourcing relations in the agro-industrial business of the Netherlands, Great Britain, Poland and Japan are analyzed. The advantages and risks of outsourcing and selection of outsourcers to perform certain functions of the enterprise are systematized. It has been proven that companies that use only internal opportunities instead of external ones (instead of outsourcing) are less innovation-oriented and cannot take advantage of opportunities to develop new value added products. It is noted that highly specialized outsourcers can do much more to create added value at a lower cost than any integrated enterprise. There are basic criteria for choosing an outsourcer determined. The expected benefits from the use of outsourcing are singled out: savings in operating costs, reduction of investment costs, supply of fresh capital, conversion of constant value into variable, improving the quality of products and services, improving the adaptability of the enterprise, access to modern technologies, focus on key activities and solutions associated with existing features. The existence of a strong positive correlation between the level of outsourcing development and production volumes, trade volumes, employment level and innovation level has been proved. The reasons for the low level of implementation and development of outsourcing in domestic vertically integrated agricultural enterprises are identified.

Authors: Pavlova Halyna , Bardadim Maria , Volchans'ka Liudmyla
Published: July 2021

The starting point in building an efficient farm with a strong market position is to ensure its stable and reliable financial position. When forecasting the result or the possible degree of achievement of goals are the likely consequences of decisions made or planned. In this sense, forecasting is a necessary component of planning and management. And the success of planning and, consequently, the management of the enterprise, will be fully determined by the quality of forecast assessments of the consequences of decisions.
Theoretical and methodological approaches to improving the system of forecasting and forecasting in farms are of practical interest and are a topical scientific problem in modern conditions.
The purpose of the study is to conduct a financial analysis of the farm to implement the project, which will allow it to predict a decrease in the duration of accounts payable and receivables and reduce the depreciation rate of technical means of the farm, which will lead to renewal of fixed assets. The use of design and forecasting measures will help to increase the efficiency of farm management.
The level of financial stability of the enterprise is analyzed and its coefficients are determined. In addition, the results of the impact of the proposed project on the partial renewal of material and technical base on the financial and economic performance of the enterprise are calculated.
The need to study the problems of design and forecasting is dictated by the fact that in Ukraine there is no optimal relationship between planned and market regulation of farm development, which does not contribute to their effective functioning. Despite the breadth of consideration by domestic and foreign researchers of design and forecasting methods in modern conditions, they are insufficiently developed and in scientific terms there are questions about the effective management of farms through their design and forecasting.
It is proved that the implementation of the proposed project will reduce the duration of accounts payable and receivables, and the depreciation rate will decrease due to the renewal of the company's fixed assets, as well as the greatest positive change will be the solvency of the company.

Published: July 2021

The article is devoted to the control and its role in the management system of the organization. This research outlines the importance of forming an effective control system at the enterprise within the integrated economic mechanism of the organization management. The article is substantiated the control as an indispensable element of the management system, which in modern conditions of enterprises functioning will allow them to provide its stable and safe development. During the research conduct, the theoretical systematization of the main aspects of the concept of control (characteristics of the main forms of control in the enterprise) has been identified. Moreover, structural characteristics (components of the control system and their detailed explanation) and intra-system properties of the management function of the enterprise (functional and organizational support, features and problems of control system at domestic enterprises) were defined. The article identifies the main forms of control (institutional, internal, market, corporate, business, social), the basic components of the control system in the economic management mechanism of the organization: objects, subjects, purpose, functions. Basic principles (such as continuity, integration, transparency, rational bureaucracy, timely prevention of adequacy and clarity) and control methods (documentary, organizational, calculation-analytical) were defined. The key tasks, the implementation of which is entrusted to the control system at the enterprise, are highlighted. The semantic components of functional (normative, methodical, software and technical, personnel and financial support) and organizational support of the control system in the general structure of enterprise management (specialized services at the enterprise, accounting departments, officials, top management bodies) are considered. The key features of control systems of the organization in modern business conditions are characterized. The main problems of formation of effective control systems at domestic enterprises are determined.

Agoraphobia: New York City Public Space in the Time of COVID-19
Authors: Mitrasinovic Miodrag
Published: July 2021

This paper explores how the first two waves of the Covid-19 pandemic (February – May 2020) in New York City had magnified extreme polarization between two different visions of public space: one clearly represented by the Hudson Yards Plaza in Manhattan, and the other epitomized by the Corona Plaza in Queens. It argues that the phenomenon of agoraphobia, the fear of others, translates into the fear of public space and by extension the fear of democracy driven by deep anxieties surrounding the definition of “the social.” This is clearly exemplified by Hudson Yards, which closed its doors to the public in May and approached early bankruptcy. On the other hand, Corona Plaza is still a vibrant public space providing vital social and community services. The Plaza was co-produced by the local communities, city agencies, the non-profit sector and public-private partnership, and it provides a resilient model for the production of public space in NYC. The paper argues that the process of producing an infrastructure of inclusion in Corona, which had preceded the construction of Corona Plaza and was strengthen through it, has enabled the Plaza to strive even during the Covid-19 pandemic.
Domestication Will Shape Future Public Spaces. A Report from Rotterdam
Authors: Harteveld Maurice
Published: July 2021

This commentary aims to provide a window on the future by studying actions, taken to control the spreading of the corona virus, while obviously affecting public space over a year. What has been the effects on public space directly linked to these actions during the pandemic; what values play a role, and what can we expect for the future? We have seen how immediate responses induced by the COVID-19 crisis influences traveling, gathering, and public live in general. Now, it is time to look further. Having a base-point in Rotterdam and taking The Netherlands as an example, the commentary argues that some shifts in using, appropriating and experiencing public space will remain. Yet, mainly those not just being immediate responses to sudden societal change, rather those which are embedded in long-term change.

Authors: DALHA ABUBAKAR KABIRU , SANI ABDU LAWAN
Published: July 2021

ABSTRACT

Sesame is an important source of income and edible oil particularly in sub-saharan Africa. Its cultivation is constrains by many factors including lack of improved varietiess, pests and disease and abiotic stresses. Creating genetic variability could provide a base upon which improvement could made. This research was carried out to evaluate the effect of Sodium Azide and Para-dichlorobenzene on Germination and Seedlings growth of three sesame varieties (Ex-sudan, E-8 and JAN-IRI). Pot experiments were conducted during 2017 and 2018 seasons using completely randomized design (CRD). The treated seeds were planted and resulting plants (M0) were allowed to produce seeds. The seeds of the M0 were used in generating M1 plants which were used to evaluate the effect of the mutagens. Few days to germination were recorded in seeds treated with 3.0 mM So dium azide (3.0 days) or 3.0 mM Para-dichlorobenzene (3.0 days) in EX-SUDAN as well as seeds treated with 3.0 mM Sodium azide (3.0 days) in E-8. Percentage germination was significantly increased The highest shoot length was obtained when EX-SUDAN was treated with 2.0 mM (19.3cm) or 3.0 mM Sodium azide (18.2cm while highest root length was obtained when JAN-IRI and EX-SUDAN were treated with either 1.0 mM Para-dichlorobenzene (4.2cm) or 3.0 mM Sodium azide (3.8cm). The mutagens (Sodium azide and Para-dichlorobenzene) could be used to create variability for genetic improvement of Sesame.

Published: July 2021

Natural events are believed to have contributed to an increased global temperature. This is caused primarily by increase in greenhouse gases effect, such as carbon dioxide (CO2). This study evaluated assessment of carbon foot prints in 3 out of the 5 Departments in the Faculty of Agriculture and Forestry, Cross River University of Technology, Obubra Campus. Purposive sampling methods was adopted to involve students studying Animal Science, Agronomy and Forestry base disciplines within the Faculty. Carbon foot print online calculator developed by (WWF, 2016) was used for the assessment. The calculator had well-structured questions to monitor carbon foot print generated by each student activities through food, home, travel and stuff. The results were analyzed using Analysis of Variance (ANOVA). Tables were used to compare with the global average planet of 3.06 tones for human existence on the earth surface. The Department of Animal Science recorded the highest carbon foot print of 614.18 tonnes requiring 6.53 tonnes planets to cohabit. The lowest carbon foot print of 469.0 tonnes was obtained in the Department of Forestry requiring 6.52 tonnes planets to exists. 500 level students generated the highest carbon foot print 356.48 tonnes requiring 7.22 tonnes of global average planets. While, the least foot print was observed in 200 level students 307.54 tonnes. The male and female students produced the same average carbon foot print of 625.3 tonnes. Investigation revealed high carbon foot print in food consumption, travel and home required more planets to sustain our lives in the

Authors: Gachi Abubakar , Nuhu Abdulhafiz A. , Abubakar Abdulkadir
Published: July 2021

WhatsApp is an instant messaging application for information exchange in real time. It is a medium for communication and interaction among individuals, groups, institutions and business partners. Enormous amount of information is generated by WhatsApp in velocity, volume and variety which can serves as a source for various analyses, prediction and for other purposes. In this paper, dataset was collected from WhatsApp Group Chat, FUDMA ASUU MATTERS (FAM), a chat group of lecturers from Academic Staff Union of University (ASUU), Federal University Dutsin-Ma, Katsina state Nigeria. The primary goal is to present detailed analysis of the WhatsApp group chat to ascertain the level of involvement and participation by members in the group. Detailed analysis of fact such as the number of messages sent in different format, the most active date and time as well as the most active user(s) is to be investigated. Text classification method with Python and Jupyter notebook was used. The Python libraries applied include, Numpy, Pandas, Matplotlib and Seaborn. The result has shown that the level of participation of members compared to top ten members is by far uneven as only the top ten members accounted for more than half of the cumulative messages sent over a period of fourteen months. The research encourages members to be actively involved instead of allowing few members to dominate the platform. It is better to be an active contributor rather than remaining as a passive onlooker
A Reconsideration on the Theory of Beauty: Previous Views and a New Approach Following Maslow's Theory (Part II)
Authors: Lehene Iulia-Adina
Published: July 2021

This paper is the second part of a work that aims to rethink the concept of beauty as close as possible to its essence and in a way that integrates the science of aesthetics with the field of construction. Within other theoretical and practical works, this study may be further used to physically reflect the definition of beauty in areas such as architecture, civil engineering or urban planning and support professionals in designing and building beautiful objects and constructions. However, it has to be added that the assumption that there must be a particular original aspect related to beauty that leads a human-made object to success, needs to be further identified. The approach to the concept of beauty is through a general philosophical perspective and partially through the areas mentioned above.The second part of the study includes the synthesised guidance provided by Monroe Beardsley through the theories on beauty from the nineteenth century until today. In addition, it comprises the scheme of concepts that characterised the beautiful in this time, including the lines that guided its study, previous ideas that support our later views on presented theory, and a brief exposition of Maslow's theory of human motivation followed by our theory on beauty and the conclusions.

Retinal vasculitis is inflammation of retinal blood vessels typically resulting from infection or immune-mediated inflammatory processes. It may present as isolated ocular inflammation or as a part of severe or potentially fatal systemic disease. Ocular complications of retinal vasculitis include cystoid macular edema, neovascularization, tractional retinal detachment, and vitreous hemorrhage, which all greatly threaten vision. Multimodal imaging and thorough systemic investigations are the main tools for making a precise diagnosis, which aids in predicting disease prognosis and visual outcome as well as preserving a patient’s vision and possibly their life. This review aims to discuss the current understanding of retinal vasculitis as well as current diagnostic tools and treatments.
MANAGEMENT OF SELF-DEFENSE OF THE MUNICIPALITIES – PREPARATION FOR THE DECISION-MAKING PROCESS AT DISASTERS
Authors: Dobó Marianna
Published: July 2021

The research, which was started in 2013 focuses on the decision-making process after vis-mayor situations (Dobó, 2013). Disaster Management in Hungary is a less known and researched area. However, over the last years natural problems had great impact on the decision making process of the local government (Csefkó, 1997). The disasters transformed the processes that had been working so far. The examination of the changed decisions became very important. Researches were carried out by the Disaster Management Department of National University of Public Service. One of the most important projects is the Critical infrastructure protection that could provide practical knowledge about the topic. The decision-making process after the crisis had not been analysed in previous studies.
This research can be divided into several parts. First, there is exploration of the theoretical frameworks, laws and regulations. The decisions of the local government and the disaster management process can be presented by becoming familiar with the previous disasters. The most important stage will be the examination of the post-disaster period when the roles and the transformation of the players can be demonstrated.
The methodology is complex. In the first phase, after consideration of the literature, the focus is on the changes of the law. The second stage contains media monitoring, document and map examination as well as interviews with the actors. In the third stage, the observation comes as a new method to the second phase: cooperative decision making process, crisis communication replacement, social reconciliation.
The topic at any time is up to date due to the fact that while the preparedness for a crisis has become more urgent, the prediction of vis-mayor situations and consequently, the preparation is almost impossible. In this context, the decision-making process of 15 municipalities, which are now live every day of their flood, pour of the river-wall or red mud disaster and after the storm, was examined.
The creation of a theoretical framework and their presentation on conferences happened so far. Processing the methodology and case studies of the disaster management are currently going on. The presentation of the achievement is expected in the autumn period.
Key words: crisis communication, decision-making, declared period’s administrative function, legal framework.
Killing them softly: a review on snake translocation and an Australian case study
Authors: Cornelis Jari
Published: July 2021

Human-wildlife conflicts with ‘nuisance’ snakes are becoming more frequent around the world as urbanisation continues to encroach on remaining habitats. In an attempt to mitigate this issue, snakes are often translocated in an uncontrolled fashion, with little to no conservation value. To determine the most appropriate methods of translocation we reviewed
the available primary literature on studies performing translocations of snakes. We found two types of translocation: long and short-distance. Based on the welfare of the animals involved and difficulty of achieving success with long-distance translocations, we deduced that short-distance translocations are the most favourable. We also reviewed the literature
on a third method - repatriating wild populations of snakes with captive-bred or captive-reared individuals, the results of which were very similar to those of long-distance translocations. In conjunction with a mark recapture study carried out by snake catchers in Darwin, Australia, we use our findings to make suggestions on the most appropriate course of action for the mitigation-based snake catching activities in Australia. The difficulty of ensuring successful outcomes for long distance translocations along with a high mortality rate meant we cannot suggest this as an appropriate method for managing ‘nuisance’ snakes. Instead, we argue that short distance translocations are the most suitable for the welfare of the snakes involved. Nevertheless, no outcome will be more favourable for the snakes than to be simply released within their home range accompanied by a change in attitude of the general public towards a willingness to coexist. Although we focus primarily on Australia our suggested framework can be applied in any country where there is conflict with snakes. Furthermore, should our suggestions be implemented, they are merely a temporary solution to an ongoing problem and we are in desperate need for further research to devise a long-term management plan.
Repeated use of high risk nesting areas in the European whip snake, Hierophis viridiflavus
Authors: Bonnet Xavier
Published: July 2021

Oviparous snakes deposit their egg clutches in sites sheltered from predation and from strong thermal and hydric fluctuations. Appropriate laying sites with optimum thermal and hydric conditions are generally scarce and are not necessarily localised in the home range. Thus, many gravid females undertake extensive trips for oviposition, and many may converge at the best egg laying sites. Dispersal mortality of neonates post-hatchling is also a critical factor. Assessing the parameters involved in this intergenerational trade-off is difficult however, and no study has succeeded in embracing all of them. Here we report data indicating that gravid females of the highly mobile European whip snake, Hierophis viridiflavus exhibit nest site fidelity whereby they repeatedly deposit their eggs in cavities under sealed roads over many decades. These anthropogenic structures provide benefits of relative safety and suitable incubation conditions (due to the protective asphalted layer?), but they expose both females and neonates to high risk of road mortality. Artificial laying sites constructed at appropriate distances from busy roads, along with artificial continuous well protected pathways (e.g. dense hedges) that connect risky laying sites to safer areas, should be constructed.

Authors: Akash Azmain A , Choudhury Fahim R , Hossain Iqbal
Published: July 2021

The application of coloring to food is widespread around the globe. Some of the artificial food colorants are highly carcinogenic. Exploration of new natural colorants has therefore been under research. The present study was aimed to evaluate Hibiscus rosasinensis flower as a potential feedstock for natural colorant. Crude anthocyanin was first extracted from Hibiscus rosasinensis flower using a Soxhlet apparatus with ethanol as the solvent. Flower to solvent ratio was found to affect the extraction largely. A ratio of 1:20 was found to give the highest fraction of extract. The cytotoxicity of crude anthocyanin extract was subsequently determined by Brine Shrimp Lethality Test. The LC50 value for crude anthocyanin extract was 2332 μg/ml, which is higher than the required minimum threshold value. Hence the findings of present study would be useful towards the application of H. rosasinensis flower as a feedstock for natural colorant to food.

Application and Performance Evaluation of Model Predictive Controllers on Driving Force Based Reactive Distillation Processes
Authors: Iftakher Ashfaq , Nahid Ahaduzzaman , Choudhury MAA Shoukat , Mansouri Seyed Soheil , Gani Rafiqul
Published: July 2021

In this work, integrated design and control of Reactive Distillation (RD) column operating under Model Predictive Controller (MPC) is presented. At first, a design target is defined, and the RD column is designed based on the element concept at the maximum driving force. After that, the steady state simulation is carried out in ASPEN PLUS that satisfies the design target. Next, the flow driven dynamic system is linearized in ASPEN PLUS Dynamics and the state space matrices are obtained. Using the matrices, MPC closed-loop simulation is carried out in MATLAB. To quantify both the steady state and dynamic operation, a multi objective function is defined that takes into account both the design (total energy consumption, total carbon footprint), and the control performance (Integral Absolute Error, total variation of input, relative gain array, Niederlinski Index). For further verification, an alternative design based on non-maximal driving force is also obtained, and the corresponding steady state and dynamic simulation is performed. The closed-loop performance of MPC controller under feed disturbance shows that the process that is designed at the maximum driving force exhibit better control performance compared to the design alternative that does not take into account the maximum available driving force.

Після практичних експериментів з відповідним мобільним додатком передавача і програмою приймача на платформі Windows встановлено, що подібна трансляція можлива тільки тоді, коли IP адреси смартфона і комп’ютера, до якого підключений монітор, знаходяться в одній підмережі, і у випадку, коли це не так, необхідно змінити місце фізичного підключення комп’ютера до локальної мережі. Детально розглянуто можливості і зручності таких мобільних додатків, як-от WPS Office і Canva – для компоновки текстової і графічної складової при створенні власного контенту. Практика запроваджених підходів до вивчення інформаційних технологій виявила неабиякий інтерес серед студентів, особливо тих, хто до цього використовував смартфон лише в якості телефонного апарата.

У статті проаналізовано можливості та специфіку використання інформаційно-комунікаційних технологій (ІКТ) для дослідження феномену кібербулінгу як актуальної проблеми молоді на сучасному етапі розвитку суспільства. Виявлено особливості, яким мають відповідати інструменти ІКТ для забезпечення ефективності психологічних онлайн досліджень, а саме: безкоштовні та зручні платформи; потужні обчислювальні сервіси для обробки та візуалізації статистичного матеріалу; комунікаційні сервіси для організації взаємодії з користувачами. Висвітлено доцільність активної співпраці спеціалістів з комп’ютерних наук та психологів щодо впровадження онлайн інструментів ІКТ з метою профілактики та протидії кібербулінгу. Описано інформаційну модель і контентне наповнення віртуального майданчика дослідження та профілактики кібербулінгу серед студентської молоді у вигляді веб-сайту, реалізованого на базі Гугл-платформи та розміщеного у вільному доступі. Розроблений сайт містить авторську анкету, адресний матеріал для потенційних учасників кібербулінгу, чат-бот для організації взаємодії з ними. Представлено ментальну схему анкетування, на основі якої за допомогою Гугл-форми створено опитувальник для діагностики проявів кібербулінгу серед студентів. Визначено його найпоширеніші причини та соціальні мережі для потенційних проявів. Представлено найбільш розповсюджені види кібербулінгу серед молоді, здійснено порівняльний аналіз гендерних особливостей їх прояву. Обґрунтовано доцільність зберігання отриманого статистичного матеріалу в Гугл-таблицях, оскільки це надає потужніші можливості його подальшої обробки із застосуванням методів аналізу даних та візуалізації у порівнянні з Гугл-формами. Встановлено, що імплементований у віртуальний майданчик чат-бот є ефективним та зручним інструментом реагування на кризові ситуації у форматі дистанційної психологічної допомоги студентам, який відповідає сучасним реаліям. Апробація розробленого віртуального майданчика в освітній діяльності вищого навчального закладу засвідчує актуальність та ефективність запропонованих онлайн інструментів для дослідження, профілактики та протидії кібербулінгу.

Several biocides are widely used in rainbow trout aquaculture against various ectoparasites and ectobionts, but the inflammation induced in treated fish is less well described. Dose-response studies were conducted to elucidate the effects on rainbow trout (gills and fins) induced by a series of biocides including formalin, hydrogen peroxide (H2O2), peracetic acid (PAA) and the surfactant SPH6, which was isolated from the bacterium Pseudomonas H6. The compounds have documented antiparasitic effects, but the specific effects on fish needs further documentation. This study was performed over 24 h, and inflammatory reactions were evaluated in gills and fins. A dose-dependent effect was noted for expression of immune genes encoding for IL-1β, TNFα, IFNγ, IL-10, IL-8, lysozyme, serum amyloid A (SAA), hepcidin, precerebellin and complement factor C3. PAA induced the strongest upregulation of cytokine and acute phase reactant genes followed by H2O2 and formalin. SPH6 showed a lower effect, and in several cases the compound induced downregulation of several genes. Gills showed a stronger response compared to fins. The mucous cell density in fins showed a range of changes which varied by compound. PAA, and to a lesser degree H2O2 and formalin, initially induced mucous cell hyperplasia, whereas SPH6 immediately decreased the number of cells containing mucus.
