Published: January 2022

Rheumatoid arthritis occurs in 0.5-1% of the adult population in developed countries. Based on data from Riskesdas (2018), there is an increase in joint disease, originally there was 7.3%, increased to 11.9%. The high incidence of Rheumatoid Arthritis is influenced by many factors, namely age, gender, genetics, sex hormones, and immunity. Rheumatoid arthritis should not be ignored, because it will damage the joints which cause severe pain. One of the measures that have been shown to be effective non-pharmacologically to reduce pain is to warm the affected joint. Warm compresses can be used in the treatment of pain and relax tense muscles. Plants that have substances as warming, anti-inflammatory and can increase blood flow such as lemongrass. The purpose of this activity is to provide education about rheumatoid arthritis and how to reduce pain by applying warm lemongrass compresses to residents in Lebak Bandung village. This service activity was carried out on 29-30 September 2020, by visiting the homes of residents who were the target of the activity. The target is the residents of Lebak Bandung village as many as 20 people. This activity consists of providing education with leaflet media and demonstrations using models. After education, all targets can understand and be able to demonstrate the application of warm lemongrass compresses. It is recommended that educational activities can be carried out routinely regarding health problems that are needed by the community

Corona Virus or known as COVID-1 9 has now spread to various countries in the world. The World Health Organization (WHO) has declared COVID-19 a global emergency. The government has made efforts to prevent the spread of Covid-19, namely by socializing 3M and 3T. The term 3M is a health protocol that every individual needs to do to avoid contracting Covid-19, namely wearing masks, washing hands, and keeping a distance. On the other hand, to identify residents who have been exposed to Covid-19, the government has termed 3T efforts, namely testing (examination), tracing (contact tracing), and treatment. The main steps that the community can take to reduce and anticipate the spread of Covid-19 are the use of masks, covering the mouth and nose when sneezing or coughing, washing hands with soap or disinfection. The purpose of this community service activity is to increase public knowledge about the prevention and implementation of health protocols during the COVID-19 pandemic. The form of activities in community service carried out by STIKES lecturer Andini Persada Mamuju by conducting health education, distributing masks, and distributing hand sanitizers. The lack of public awareness and knowledge regarding Covid-19 can be overcome by providing information in the form of health education about the importance of implementing health protocols. . This step is something that must always be applied by the whole community, especially the people of the Bamboo Village, Mamuju Regency. Information and education must continue to be provided to the public, as well as carry out supervision so that people want to implement healthy lifestyle behaviors to prevent the spread of Covid-19. Socialization activities in the form of health education, distribution of masks, hand sanitizers are one effective way to educate the public.

Clean water is one of the basic needs for human life. Making simple raw water treatment equipment using a filtration system is expected to help the community to process dirty water into raw water on the scale of household needs. Poor water quality will affect the health of existing residents. There is a need for innovation in the manufacture of water filters in order to improve the quality of water for daily needs so that it becomes a more useful product or material. The method used in achieving the goal is to provide training in making simple water filters. The right method used for processing turbid water from household dug wells into clean water in an area is to use the multilevel filter method. This filtering process is to remove suspended solids or the separation process between solids/colloids and liquid solids. The conclusion in this activity is that the training on making simple water filters can be accepted by local residents to get clean and not cloudy water. It is hoped that with this activity there will be more efforts and willingness from the community to improve the quality of healthy life by paying attention to aspects of the availability and use of clean water

New Challenge for Business - Financial Reporting
Authors: Mariam Girsiashvili Mariam Girsiashvili
Published: January 2022

In the 21st century, international accounting standards are being introduced in more and more countries, which is a way of comparing the economic indicators of countries in the world economy. Many enterprises around the world submit financial statements to external customers. Although the financial statements of different countries are similar to each other, there are still some differences between them, which is due to many social, economic and legislative factors. Also, the creation of national accounting standards in these countries takes into account the interests of different categories of financial reporting users.
These differences are the reason why the financial statements of all enterprises are accompanied by explanatory notes, which provide an explanation of each element of the financial statements in accordance with the accounting policies of the enterprise. Reducing these differences is the goal of the International Accounting Standards Board (IASB).
The purpose of this article is to review the impact of the changes for enterprises registered in Georgia. Enterprises registered in Georgia from 2019 will face various obligations, which have led to changes in Georgian tax legislation and the introduction of international accounting standards. Accordingly, the management of the company focused on bringing each operation carried out in the company in compliance with international standards and Georgian legislation.
The purpose of financial reporting is to create a transparent and trustworthy business environment in the country. From 2019, enterprises will submit financial statements to the Accounting, Supervision and Audit Supervision Service. The submitted report is important for creating a transparent business environment and allows the country to be more informed, to have information about the current economic situation in the country. Consequently more submitted reports are important to get information about the economic situation of the country.
The information presented in the article builds on the experience gained over the last 4 years, which includes the provision of financial reporting services in various sectors. Surveys conducted by company management and accountants and experience gained in preparing financial statements have had a significant impact on the findings in this article.

Published: January 2022

Changes in mathematics identity over time were examined as well as beliefs regarding the nature of mathematics identity and experiences with mathematics that might be related to mathematics identity development.  Survey data from 131 college students were analyzed using a Wilcoxon Signed-Rank test to assess longitudinal changes in self-perceptions about mathematics identity.  In addition, open-ended responses were analyzed using a phenomenological approach to examine experiences with and beliefs about mathematics. The results indicate that mathematics identity, as reported by students, is a stable measure over time. Several overarching themes emerged from the qualitative data to indicate that participants’ reported formative experiences center around to performing in mathematics and teaching others or sharing mathematics. A majority of participants believe it is possible to become a “math person”; however, an underlying belief that mathematics is an innate ability is also evident.
Wittgenstein’s Antifoundationalism: a response to Cristiane Maria Cornelia Gottschalk
Authors: Peters Michael
Published: January 2022

Michael Peters writes “Wittgenstein’s Antifoundationalism: a response to Cristiane Maria Cornelia Gottschalk” to assert that one is always indebted to those who take their work seriously and engage in serious disputes over readings and arguments. For Petters, Cristiane Gottschalk advances in three aspects of disagreement: (i) the appropriation of Wittgenstein’s philosophy by analytic philosophers of education; (ii) the status of Wittgenstein’s spelling dictionary; and (iii) Wittgenstein's anti-foundationalism. Thus, he discusses and presents his arguments on the three arguments in his text.
RELIABILITY OF SPATIALLY-REFERENCED SECONDARY ECONOMIC DATA: VALIDATION, ISSUES, AND SOLUTIONS
Authors: SÎRODOEV Igor
Published: January 2022

In the era of ever-increasing data supply, range and diversity, there is a strong need to compare and assess the reliability of the data coming from various sources. For secondary economic data, such sources are usually grouped into two big categories: surveys carried on and statistical records kept by governmental bodies (statistical agencies); and commercial data, collected by private companies from various public (or confidential) sources. The article discusses the benefits and pitfalls of these data categories on the example of the two data providers in Romania, whose data are widely used in economic research and for the development of public policies: National Institute of Statistics (NIS) and Borg Design S.R.L. (BD). The quality control of the data provided by NIS is more transparent and it is rigorously based on the international standards applied in the field of official statistical surveys; however, the spatial resolution of these data is quite coarse, while being usually available at the level of counties. In turn, the data provided by BD have a much finer spatial resolution (down to the level of villages) but their quality control is less transparent. In conclusion, the analyzed data are complementary and they can be used for analytical purposes, taking into account their limitations.
BANGKOK’S URBAN SPRAWL: LAND FRAGMENTATION AND CHANGES OF PERI-URBAN VEGETABLE PRODUCTION AREAS IN THAWI WATTHANA DISTRICT
Authors: MENAKANIT Alisara , DAVIVONGS Vudipong , NAKA Prapassara , PICHAKUM Nath
Published: January 2022

Urban sprawl is a global phenomenon that has transformed the surrounded agricultural lands over the fringe of megacities. Vegetable production areas in the Bangkok’s peri-urban area have been at risk for changing due to the influences of urbanization. This study on the prime vegetable production areas in Bangkok, Thawi Watthana district, aimed to: 1) understand and determine the land use changes to these areas, 2) clarify the landscape configurations of these areas to assess landscape fragmentation, 3) discuss and recommend land use planning policies and measures to conserve the existing peri-urban agricultural landscape. A geographic information system (GIS) database and three thematic map layers (land use, waterways, and roads) were created and analyzed to clarify land use proportions, changes in the vegetable production areas, and the land configurations during different periods from 1976 to 2015. The Spatial Analyst in the ArcGIS 10.3 program was utilized. The results showed that vegetable production areas in the district decreased at a rate of 20.38 ha/y, even though the district was designated as an agricultural area in the Bangkok’s land use planning policies. The fragmentation of the vegetable production matrix (indicated by patch number, patch density, and mean patch size) increased due to the immediate effect of the expanded road network construction and due to a later consequence of the contiguous roadside urban development. The remaining vegetable production areas were mostly away from the primary road leading to the Bangkok center city. The monitoring system on the fragmentation of agricultural lands is essential as a database to find suitable measures to control urban sprawl in various cities.
Dirichlet problem with measurable data for quasilinear Poisson equations
Authors: Gutlyanskii Vladimir , Nesmelova Olga , Ryazanov Vladimir , Yefimushkin Artem
Published: January 2022

The study of the Dirichlet problem with arbitrary measurable data
for harmonic functions in the unit disk $\mathbb D$ goes to the
famous dissertation of Luzin, see e.g. its reprint \cite{L}. His
result was formulated in terms of angular limits (along nontangent
paths) that are a traditional tool for the research of the boundary
behavior in the geometric function theory.

Following this way, we proved in \cite{GNR1} Theorem 7 on the
solvability of the Dirichlet problem for the Poisson equations
$\triangle\, U=G$ with sources in classes $G\in L^p,$ $ p>1$, in
Jordan domains with arbitrary boundary data that are measurable with
respect to the logarithmic capacity. There we assumed that the
domains satisfy the quasihyperbolic boundary condition by
Gehring--Martio, generally speaking, without the known
$(A)-$condition by Ladyzhenskaya--Ural'tseva and, in particular,
without the outer cone condition that were standard for
boundary-value problems in the PDE theory. Note that such Jordan
domains cannot be even locally rectifiable.

With a view to further development of the theory of boundary value
problems for semi-linear equations, the present paper is devoted to
the Dirichlet problem with arbitrary measurable (over logarithmic
capacity) boundary data for quasilinear Poisson equations in such
Jordan domains.

For this purpose, it is first constructed completely continuous
operators generating nonclassical solutions of the Dirichlet
boundary-value problem with arbitrary measurable data for the
Poisson equations $\triangle\, U=G$ with the sources $G\in L^p,$ $
p>1$.

The latter makes it possible to apply the Leray-Schauder approach to
the proof of theorems on the existence of regular nonclassical
solutions of the measurable Dirichlet problem for quasilinear
Poisson equations of the form $\triangle\, U(z)=H(z)\cdot Q(U(z))$
for multipliers $H\in L^p$ with $ p>1$ and continuous functions $Q:
\mathbb R\to\mathbb R$ with $Q(t)/t\to 0$ as $t\to \infty$.

As consequences, we give applications to some concrete quasilinear
equations of mathematical physics, arising under modelling various
phy\-si\-cal processes such as diffusion with absorption, plasma
states, stationary burning etc. These results can be also applied to
semi-linear equations of mathematical physics in anisotropic and
inhomogeneous media.
Shape optimization in elliptic problem with nonlinear boundary conditions
Authors: Krasnoshchok Mykola
Published: January 2022

Shape optimization problems have a long history of
mathematical study and a wide range of applications. In recent
decades there has been an interest in solving these problems with
partial differential equation (PDE) constraints. In practice we
often meet problems, leading to the problem of finding an “optimal”
shape of systems, the behaviour of which is described by elliptic
equations. Problems of this type have been studied by many authors
from mathematical as well as from computation point of view. When
surfaces of a specimen which have been damaged by a corrosion
aggressive attack are not accessible to direct inspection, one is
forced to rely on over-determined measurements performed on the
accessible part of the boundary. In this study, we consider such a
non-destructive inspection technique modelled as a shape
optimization problem, which consists of determining an unknown part
of the boundary of a simply-connected bounded domain. The solution
of Laplace equation $u$ satisfies nonlinear Robin condition on an
unknown part of boundaty. We have Dirichlet and Neumann boundary
conditions on the rest of boundary. We look for a curve, that
minimizes the cost functional represented as a sum of regularizing
term and $L_2$-norm of the difference of the state variable $u$ and
some additional measurement on the part of admissible boundary. The
existence of at least one curve is proved for an appropriate choice
of the class of admissible curves. This will lead us to study
properties of continuity of J and compactness of the set of
controls. We shall characterize the shape derivative of the cost
functional with respect to perturbations of the domain defined by a
sufficiently smooth function. In order obtain necessary optimality
condition we use the mapping method. This method transforms the
unknown domain to a fixed one. The problem under consideration is
essentially nonlinear. We prove Frechet differentiability of the
solution operator.
Experiments on Recognition of Infinite Grid Graph Labelling
Authors: Sapunov Sergiy
Published: January 2022

In recent years, topics related to automaton analysis of geometric environment have attracted widespread attention. The interaction of an automaton and an environment is often represented as a process of an automaton walks along a graph (labyrinth) of environment. Treating environment as vertex-labelled graph was suggested as one approach to addressing the problem of automaton analysis of environment properties. Research in this regard received a wide range of applications, for example, in the problems of image analysis and navigation of mobile robots. This paper considers a four-way infinite lattice graph as a model of an environment for a graph-walking automaton. All vertices of this graph are labelled with labels from a known set but concrete labelling function is not a priori known. The automaton looking over neighbourhood of the current vertex and may travel to some neighbouring vertex selected by its label. The objective of the automaton is to determine two pairs of opposite directions on the aforementioned graph embedded onto integer lattice, i.e. recognizing the graph labelling. In previous work we have proposed a labelling thanks to which a finite automaton can walk on graph in any arbitrary direction. We have called this labelling deterministic. We have proved that minimal deterministic vertex labelling of infinite lattice graph uses labels of five different types. The paper demonstrates that there exists 240 different minimal deterministic labellings of the infinite lattice graph with a fixed set of labels. We prove that a single automaton cannot recognize minimal deterministic labelling of the infinite lattice graph, but automaton with one pebble can. The novelty associated with this paper is a new type of experiment with vertex labelled graphs designed to recognition their labelling. The method of constructing and performing recognition experiment for labelled infinite grid graph is proposed.
Linear differential-algebraic boundary value problem with nonsingular pulse influence
Authors: Chuiko Sergiy , Chuiko Elena , Shevtsova Kateryna
Published: January 2022

The study of differential-algebraic boundary value problems was initiated in the works of K. Weierstrass, N.N. Luzin and F.R. Gantmacher. Systematic study of differential-algebraic boundary value problems is devoted to the work of S. Campbell, Yu.E. Boyarintsev, V.F. Chistyakov, A.M. Samoilenko, M.O. Perestyuk, V.P. Yakovets, O.A. Boichuk, A. Ilchmann and T. Reis. The study of the differential-algebraic boundary value problems is associated with numerous applications of such problems in the theory of nonlinear oscillations, in mechanics, biology, radio engineering, theory of control, theory of motion stability. At the same time, the study of differential algebraic boundary value problems is closely related to the study of pulse boundary value problems for differential equations, initiated M.O. Bogolybov, A.D. Myshkis, A.M. Samoilenko, M.O. Perestyk and O.A. Boichuk. Consequently, the actual problem is the transfer of the results obtained in the articles by S. Campbell, A.M. Samoilenko, M.O. Perestyuk and O.A Boichuk on a pulse linear boundary value problems for differential-algebraic equations, in particular finding the necessary and sufficient conditions for the existence of the desired solutions, and also the construction of the Green's operator of the Cauchy problem and the generalized Green operator of a pulse linear boundary value problem for a differential-algebraic equation. In this article we found the conditions of the existence and constructive scheme for finding the solutions of the linear Noetherian differential-algebraic boundary value problem for a differential-algebraic equation with nonsingular impulse action. The proposed scheme of the research of the linear differential-algebraic boundary value problem for a differential-algebraic equation with impulse action in the critical case in this article can be transferred to the linear differential-algebraic boundary value problem for a differential-algebraic equation with singular impulse action. The above scheme of the analysis of the seminonlinear differential-algebraic boundary value problems with impulse action neralizes the results of S. Campbell, A.M. Samoilenko, M.O. Perestyuk and O.A Boichuk and can be used for proving the solvability and constructing solutions of weakly nonlinear boundary value problems with singular impulse action in the critical and noncritical cases.
STATE AND PROSPECTS OF BEAN PRODUCTION OF COMMON BEANS AND VARIABILITY OF INTERPHASE PERIODS
Authors: Stashevsky Roman
Published: January 2022

In recent years, Ukraine has significantly increased exports of beans, taking the position of a key exporter of this crop from the Black Sea region, considering them as an opportunity to diversify production, and if soybeans are already grown on a large scale, then niche experiments are experimented with on small areas - from 100 hectares and more. The expansion of industrial bean production is due to the growing demand for it in the domestic and world markets. At the same time, beans grown on households do not always meet the needs of commercial companies and processing enterprises. Commodity batches that are multiples of machine standards, ie from 4 and more tons, are in demand on the market. Provided that the product must belong to the same variety in order to be uniform in size, color, structure, etc. This can be achieved in the case of industrial cultivation of beans or the organization of its cultivation in private farms through the creation of service agricultural cooperatives. The growing season of common beans consists of the following phases of growth and development: the second - from the appearance of mass shoots to the first true leaf; the third - from the appearance of the first true leaf to the appearance of the first branch; fourth - from the appearance of the first branch to flowering; fifth - from flowering to the appearance of physiologically mature seeds.It was found that the coefficient of variation (V = 16.7%) the lowest variability of the period from sowing to emergence is typical for varieties: UD0300019, UD0300495, UD0302223 - 8.0%. Plants in the phase from the emergence of mass seedlings to the true leaf proved that the low coefficient of variation (V = 5.6%) had varieties UD0302223 and UD0300232, the other samples responded actively to growing conditions.

The article presents the data of experimental studies conducted during 2018-2020. The main task of the research was to study the impact of technological methods of cultivation on varietal technology of chickpea cultivation in the Right-Bank Forest-Steppe of Ukraine given current trends in climate change. It was found that field germination varied depending on the pre-sowing treatment of seeds and varietal characteristics, and the survival of plants in the field – in addition to the studied cultivation techniques, also from the treatment of vegetative plants. It is established that the period of emergence of seedlings is extremely important in the formation of their survival rate, which will ultimately increase the individual productivity of plants and yields. Based on the analysis of the obtained indicators of field germination of seeds of chickpea varieties, it was found that the effect of pre-sowing seed treatment on the studied indicator is not significant as the intensity of seed germination is due to endosperm, which contains its own spare nutrients.
The relevance of the research is enhanced by the objectives of applied research performed at the Faculty of Agronomy and Forestry of Vinnytsia National Agrarian University at the expense of the state budget on the topic: «Development of methods for improving the technology of growing legumes using biofertilizers, bacterial preparations», (state registration number 0120U102034). Introduction of advanced technological methods of chickpea cultivation into wide production
practice will allow to reduce the deficit of fodder and food protein, increase fertility and improve the soil structure to ensure the rational use of natural potential, which will further expand the sown area of legumes.

This article presents the results of studying the development and formation peculiarities of the number of dominant phytophages of winter oilseed rape: cruciferous fleas (Phyllotreta undulata), rape pollinator (Athalia rosae L.), rapeseed flower beetle (Meligethes aeneus F.), seed larvae (Ceuthorrhynchus assimilis Payk.), cabbage capsicum mosquito (Dasyneura brassicae Winn.), cabbage aphid (Brevicoryne brassicae L.). Theoretical generalization of the prevalence of pests in the research area and the impact on the formation of winter rape yields. The influence of modern insecticides on the control of the number of dangerous pests of winter rape and on the yield, biometric parameters of rape plants has been studied. The best results in controlling the number of dominant phytophages in the enterprise showed the drug Nuredin ™ Super KE (chlorpyrifos 400 g / l + bifenthrin 20 g / l) at a rate of 0,75 l / ha. On the basis of the obtained data it is recommended to use the drug Plenum 50 VG (pimetrosine 500 g / kg) at a rate of 0,25 l / ha, as its use provides rapeseed yield at 24,3 c / ha and gives a good economic effect, due to higher yields, the profitability of growing crops is 62,8%, which is 26,3% more than the control option for improving the control over a number of pests.
Having researched the phytosanitary condition of winter rapeseed crops, it has been found that the most common diseases of rapeseed were alternaria, phomosis, gray and white rot, and cylindrosporiosis.The results of treatment of winter rape plants with new fungicides to protect against the main common pathogens: alternaria (Alternaria brassicicola Wilts), phomosis (Phoma lingam Desm.), cylindrosporiosis (Cylindrosporium concentrium Grev) are presented. Conclusions are made on the effectiveness of the new generation of fungicides in limiting the spread of diseases. To control the spread of diseases in the agrophytocenosis of rapeseed, it is advisable to use the drug Architect SE (pyraclostrobin 100 g / l + calcium prohexadione 25 g / l + mepiquat chloride 150 g / l) at a rate of 2.0 l / ha, which significantly reduced the damage of winter rapeseed major diseases and had a therapeutic effect, while providing yield at the level of 26,1 c/ha and profitability within 63,1%, which is 26,6% higher than the control option. Therefore, the use of an integrated pest management system can significantly increase the efficiency of cultivation technology and minimize crop losses.

Published: January 2022

The article substantiates the relevance of research in the context of global trends in organic agriculture, analyzes the development of organic production in Ukraine and abroad, shows the main problems of domestic organic production.
It has been noted that in recent decades, agriculture around the world has had an increasing negative impact on the environment than any other sector of the economy. This industry occupies huge areas, creating unstable landscapes. This destroys natural vegetation, including forests, disturbs water balance due to land reclamation, soil degradation is observed, groundwater and surface water are contaminated, and the fertile part of the soil is removed along with the crop.
Research has shown that Ukraine has all the prerequisites for the development of organic production: favorable climatic conditions, fertile soils, low levels of mineral fertilizers and plant protection products, a significant market of potential consumers, innovative developments in agriculture, positive experience of organically oriented enterprises, and most importantly - in the world there is a growing demand for organic products.
Factors that can influence the development of the organic market and increase interest in such products from buyers have been identified. The necessity of transition to organic agriculture and its compliance with the goals of sustainable development is proved.
The author are offered the main directions of actions that will promote the development of the Ukrainian organic market, namely: promoting the development of agricultural land under organic farming through the development of farming and the formation of marketing infrastructure; development of the state policy in the field of formation of culture of food of the population; training of qualified personnel.

One of the main factors in increasing the yield of potato tubers is the intensification of its production, which involves the creation and introduction into
production of intensive varieties. To obtain a consistently high yield of potatoes, it is necessary to have not only high-yielding varieties, productive seed material, appropriate agronomic background, but also a ratio of technological measures that would ensure optimal action and interaction of each of the effective factors. As a result of the conducted researches it was established that the highest among the studied varieties were the indicators of the weight of the tops of one bush in the variety Granada, which was noted in all variants of the experiment. Thus, in the control variant, the weight of the tops of one bush in the phase of full germination varied from 46 to 50 g, in the phase of budding from 241 to 261 g, in the phase of full flowering from 323 to 361 g
ha of semi-roasted manure, Kalimagnesia (K56Mg16S30) and simple phosphate (P30) under the main cultivation, the weight of the tops of one bush increased in the phase of full germination from 48 to 56, in the budding phase from 252 to 272 g, and in the phase of full flowering from 369 to 401 g .
The weight of the tops in the Granada variety was higher on the experimental variant, where against the background of application of 40 t / ha of semi-roasted manure, Kalimagnesia (K56Mg16S30) and simple superphosphate (P30) under the main tillage and during planting in rows. and in feeding on Nitroammophoska seedlings (N30P30K30), the weight of the tops in the phase of full germination varied in the phase of full germination from 56 to 63 g, and in the phase of budding from 269 to 292 g, and in the phase of full flowering from 402 to 449 g. In the same
variant the highest area of a leaf surface which changed in a phase of full sprouts from 11,7 to 12,9, and in a phase of budding from 20,4 to 21,8, and in a phase of full flowering from 25,9 to 27.2, in the phase of extinction of the tops from 26.6 to 28.2 m².
