Published: June 2022

The aim of this study is to compare Least Squares Regression (LSR) and Principal Components Regression (PCR) results when multicollinearity is determined in a dataset.In order to examine the effect of the degree of multicollinearity in the study, 10 datasets with different levels of multicollinearity were derived. Each data set consists of three independent and one dependent variable, and the variables were derived from the standard normal distribution. The multicollinearity status in the derived data has been demonstrated by the commonly used metrics to determine multicollinearity. Least Squares and Principal Components Regression was applied to all datasets.
When generating multicollinearity, all relationships were defined as positive in data simulation. However, the sign of the regression coefficients for the second (X2) and third (X3) independent variables were obtained as reverse (negative) as one of the expected effects of multicollinearity in Least Squares analysis. In the analysis of the Principal Components Regression, the sign of coefficients was found to be in the right direction (positive). The sign of the coefficients obtained from OLS and PCR were different and they also differed in magnitude. In addition, the standard errors of the coefficients in PCR results were lower than OLS results.
The existence of multicollinearity must be examined while performing multiple linear regression analysis, and if multicollinearity is determined, one of the methods that can solve this situation should be used. Otherwise, the estimations to be made as a result of regression may lead to wrong results. In line with the results of this study, it is recommended to use Principal Components Regression instead of Least Squares regression in case of multicollinearity in the data.

Published: June 2022

Segundo Rita de Cássia (2003), o turismo é uma prática social que vem mudando ao longo da história e cada nova definição consiste em nova tentativa de se conceituar algo que tem, reconhecidamente, uma dinâmica inquestionável. Se trata de uma pesquisa desenvolvida como etapa do projeto CNPq (MCTIC/CNPq n.28/2018 (protocolo 429976/2018-6) desenvolvido entre os anos de 2019/2020 pelo Grupo de Pesquisas GIDs. Na primeira fase do projeto foi aplicado um inventario turístico para obtenção de dados, assim como um previsto agendamento de visita de campo para conhecermos e obter dados para segunda fase do projeto que consiste no mapeamento de um roteiro turístico e elaboração de um artigo científico. Obtendo dados de setores turísticos do município, como geossitios, artesanatos, igrejas, eventos, museus e rotas. Sendo assim, a segunda fase do projeto foi interrompida em decorrência da pandemia acerca todo o mundo, em relação ao Covid-19, a quarentena e restrições de visitas a locais públicos, a fase dois foi interrompida, tendo em vista apenas algumas informações obtidas através de contato pessoal com a secretaria de turismo no município de Cabaceiras.
Representation of knowledge in an intelligent control system for take-off and landing of a robot helicopter based on a frame model
Authors: Дайебал Джаффар Бакер Джабар 
Published: June 2022

Задача представления объектов в пространстве возникает в области автоматического и автоматизированного управления винтокрылыми летательными аппаратами. Она характеризуется требованиями высокой точности и скорости решения, а также должна решаться с минимальными вычислительными ресурсами. Робот-вертолет может использовать результаты наблюдения в пространстве как для задачи движения, так и для задачи наблюдения за другими объектами. В обоих случаях наблюдаемая картина не является строго детерминированной, так как представление положения робота-вертолета связано с бесконечным числом вариаций наблюдаемой сцены и поведения окружающих предметов. По этой причине классические строго формализованные подходы не дают желаемого эффекта. Кроме того, бесконечная вариация требует от автономного управляемого объекта разумного поведения. Избежать данной проблемы можно путем решения задачи представления знаний в интеллектуальной системе управления роботом-вертолетом таким образом, чтобы модель положения и сами действия по управлению описывались в терминах, используемых оператором. В данной статье предлагается подход к решению задачи представления знаний, базирующийся на гибридизации фреймовой модели и нечеткой логики, что позволяет избежать необходимости предварительного учета вариаций сцены и наблюдаемых объектов, а также автоматизировать задачи управления взлетом и посадкой.
The task of representing objects in an area comes from the field of automatic and automated control of rotary-wing aircraft. It is characterized by the requirements for high accuracy and speed of the solution and must also be solved with minimal computational resources. A robot helicopter can use the results of observation in space both for the task of movement and for the task of observing other objects. In either case, the observed picture is not strictly deterministic. Its representation is associated with an infinite number of variations in the observed scene and the behavior of surrounding objects. For this reason, classical strictly formalized approaches do not give the desired effect. Also, infinite variation requires an intelligent behavior from the autonomous controlled object. This problem can be avoided by solving the problem of knowledge representation in the intelligent control system of the robot helicopter in such a way that the position model and the control actions themselves are described in terms used by the operator. The paper proposes an approach to solving the problem of knowledge representation, based on the hybridization of the frame model and fuzzy logic, which avoids the need to take into account the variations of the scene and observed objects, as well as automate the tasks of take-off and landing control.

В статье приведены результаты первичных интродукционных испытаний культиваров рода Chamaecyparis: изучены биоморфологические особенности десяти садовых форм. Установлено, что прирост лидирующих побегов варьирует от 6 до 13 см в год, в неблагоприятный 2019 г. - от 2 до 7 см; прирост боковых побегов - от 4 до 13 см, в 2019 г. - от 1 до 6 см. При соблюдении необходимых мер по уходу (обеспечение полива в засушливый период, своевременные подкормка и обрезка) исследуемые культивары могут быть рекомендованы к широкому использованию в озеленении.
The collection of the Botanical Garden of the Adyghe State University includes 22 cultivars of five species of Chamaecyparis Spach. of different age groups (age 8-34). The paper presents the results of primary introduction tests of cultivars of the genus Chamaecyparis: the biomorphological features of ten garden forms are studied. It has been found that the typical rate of growth of leading shoots is 6-13 cm per year, in unfavorable 2019 - from 2 to 7 cm; the rate of growth of lateral shoots is 4-13 cm, in 2019 - from 1 to 6 cm. Our results suggest that if the necessary care measures are observed (watering in the dry period, timely fertilizing and pruning) the studied cultivars can be recommended for widespread use in landscape setting.

The Impact of the Communicative Behaviour in Social Media on the University Brand Image
Authors: Kazaishvili Ana , Khmiadashvili Lia 
Published: June 2022

Purpose: Communicative behaviour as a state of relationship which influences bilateral feelings, needs, and thoughts for more unambiguous and open communication (Ivanov & Werner, 2010) can affect the brand image. Correspondingly, communication from the side of the universities toward students through social media has a significant role.
Facebook is a powerful communicational channel. It effectively and efficiently took control of the business sector, advertising sector, and furthermore, educational realm. It has an enduring influence on the way how people communicate, and as time passes, it becomes an essential part of their lives.
The article presents the behaviours of Georgian higher educational institutions in social media, especially on Facebook, and the attitude of the existing or potential students towards communicative behaviour of HEIs. The findings show what kind of influence does communication in Facebook has on customer perception and correspondingly brand image.
Study design/methodology/approach: Considering the sensitivity and nature of the research two types of studies were selected. Observing the behaviour of the universities directly on their Facebook pages was selected as the leading type of the research, since the content, as well as their responsiveness and engagement in further communication, is clearly visible visually. In addition, we have decided to listen to the customers themselves. Because of this reason focus groups of existing and potential students were selected to talk about their expectations and the reality in terms of communicative behaviour of the universities.
Findings: The results of both, observation as well as focus group research showed the lacks and lapses of communicative behaviour of Georgian universities on social media, specifically on Facebook. The most crucial ones were detected to be the following: delays in distributing valuable information, content not so much significant and interesting for students, indirect answers to student queries or ignoring at all.
Originality/value: Considering the globalizing landscape branding has become crucial for the universities for different reasons. Not only attracting potential students but also for retaining the existing ones and being exceptional they have to follow modern trends. Communication, direct or indirect, being one of the most significant for branding deserves more attention. The value of the current research is showing the expectations of the existing and potential customers and presents the gaps between “what is done” and “what should be done”.
Industry 4.0 and Industry 5.0 from the Lean perspective
Authors: Souza Raphael , Ferenhof Helio , Forcellini Fernando 
Published: June 2022

Purpose: Despite the significant attention that Industry 4.0 (I4.0) has gained in the last decade, little importance has been given to shop-floor workers' role in effectively implementing these new technologies in production systems. Nowadays, several authors discuss the need to bring workers back to the center of the decision-making about implementing the new technologies in what is being called Industry 5.0 (I5.0). A key factor of using these new concepts is that it must make sense, and the new information generated by these technologies must have a precise use; otherwise, it will be considered waste. The Lean approach is already recognized as the best approach to identify and eliminate waste from production systems. Not only that, but it allows decisions about process improvement to be human-centric. Thus, this article aims to present the main aspects and evolution of I4.0 and I5.0 over time, using the Lean approach as the analysis lenses.
Study design/methodology/approach: In order to identify the mains aspects of I4.0 and I5.0, we develop a consistent literature review using the Systematic Search Flow (SSF).
Findings: As a result, it was possible to identify the evolution from I4.0 to I5.0, In I4.0, the main focus was on developing new technologies, combine them with classic Lean tools (e.g. Kanban 4.0, Poka-Yoke 4.0) and implement Cyber-Physical Systems. In I5.0, the focus is to use these new technologies together with shop floor workers to continuously improve production processes. Not only that, but in I5.0, the protagonist becomes (or return to become) the shop floor workers to lead the improvements, as is in the Toyota Kata approach.
Originality/value: This work presents a new way of interpreting the progression of concepts from I4.0 to I5.0. In addition, the focus on workers for problem solving is returning to the center of the discussion. Together with the technologies of I4.0, this represents a new area for future research.
Digital Divide and the Opportunity Dimension of Economic Inequality: The Case of the Republic of Moldova
Authors: Pisica Rodica 
Published: June 2022

Purpose: to analyse how the Republic of Moldova has been coping with digital inequality during the pandemic and the extent to which the digital divide has impacted the economic inequality in the country, as well as to understand what leads to digital disparities.
Study design/methodology/approach: In this research, the level of preparedness of the Moldovan households for the digitalization needs that occurred as a result of the pandemic and the both ways impact of the opportunity dimension of economic inequality and digital divide have been analysed, as well as how the lack of ICT utilities deprived certain social layers of economic opportunities during the pandemic. Concurrently, the causes of digital divide in the Republic of Moldova have been analysed to get a deeper understanding of the digital discrepancies that resulted in lack of economic opportunities. For this purpose, the data on the access to mobile phones and computers, notebooks, tablets of Moldovan households and the connection to the Internet have been analysed and the digitalization trend has been contrasted with the disposable-income based economic inequality data (Gini index). The data used for the analysis have been retrieved from the National Bureaus of Statistics (NBS) of the Republic of Moldova and has been segregated per urban and rural areas as well as per quintiles. In addition, in order to understand the cause of digital divide and the impact on economic opportunity, we have added two more variables to the equation and namely, the absolute poverty and the employment indicator for the pandemic period (2019-2020).
Findings: Covid-19 found the Moldovan households unprepared for the digitalization needs generated by the pandemic. Even though deeper in the rural area, the digital divide has enhanced the economic inequality especially in the urban area during the early pandemic period. The high absolute poverty in the rural area and the increasing trend in the urban area, associated with a decreasing employment rate especially in the cities, represent a presumed outcome of the Moldovan digital unpreparedness which enhanced the economic inequality by affecting its opportunity dimension.
Originality/value: The novelty of the research is that the impact and interlink between two types of inequality (digital and economic) in the Republic of Moldova have been analysed with a special focus on the opportunity dimension of economic inequality.

Published: June 2022

Purpose By considering the lack of studies of the factors that influence the adoption of 4.0 technologies in manufacturing SMEs, this study proposes a model that examines the aspects that motivate, benefit and obstruct the implementation of emerging technologies, as well as the role of the institutional environment, for a developing country. Methodology A qualitative approach and interview method were used to study 4.0 technologies in the “core” productive processes adopted in 25 SMEs. The gathered data were analysed and processed in NVivo 12 software. Results Two groups of categories (nodes) were obtained, within which related subcategories (subnodes) were located. These two groups are existing and emerging categories, which reflect the aspects that motivate, benefit and obstruct the adoption of 4.0 emerging technologies. Conclusions The identification of an emerging variable in the study of inhibitors and facilitators of the adoption and implementation of 4.0 technologies is a valuable contribution because it allows us to account for the problematisation of financing as an important variable in the processes of introduction into Industry 4.0 for SMEs. This proposal may facilitate public policies at regional and national level to promote and advance in this area of innovation for SMEs.

A New Azo-base-ligand was prepared [4-(( (Z)-(2,4-diclorophenyl)diazenyl)-3-((Z)-2-oxoindoline-3-ylidene)amino), (4DCPD)]-(Pyrimidine-2-yl)benzenesulfonamide). This ligand (4DCPS) with the metal ions Co(II), Ni(II) and Cu was also prepared in reaction to three chelate complexes (II). UV-Vis. Ligand along with its metal complexes were investigated based on spectra. In comparison to the one from free ligand, the (UV-Vis) electronic complex spectra showed bathochromic shifting. The Free ligand spectrum Mass & 1HNMR has been taken and the Ligand FTIR spectra and its chelating complexes studied, indicating that there is coordination among the metal ions and the prepared ligand. A conductivity and magnetics, an elementary micro-analysis and the metal ion percentage were identified. The geometrical structure of the co(II), Ni(II) and Cu preparations depends on the results of these projects (II) and they are octahedral. The mole-ratio (M:L) is (1:2). The conductivity measurements show non-electrical properties, for all prepared complexes.The final stage involved the study of the biological activity of prepared component to two type of pathogenic bacteria: (G+) Staph. aureus and Escherichia coli (G-) using Well diffusion methods .Three different concentration were tested (100 ,500, 1000) ppm in Ethanol Absolute(99%) as a solvent . The prepared compounds showed different results (high, moderate, low, and inactive).

Published: June 2022

Education in congregations is often characterized by the lack of exemplary Christian teachers who teach, foster, and educate them. This example is closely related to the professionalism of Christian teachers in fostering congregations in a consistent, dynamic, effective, and enjoyable way. The professionalism of Christian teachers in teaching and nurturing congregations is the key to bringing the congregation to the perfection of life like Christ. The life and character of the Christian religion teacher greatly influence the life and character of the congregation. A Christian teacher who teaches and nurtures congregations must have a spiritual experience with God have the ability of knowledge, skills, and ability to use methods in the learning process. The method of fostering congregations is one of the most professional teachers of Christianity in fostering a very strategic congregation. Because with this ability, it is possible for Christian religious teachers to be able to bring influence to the quality and spiritual life of the church. Thus, the church has the knowledge of faith in the truth of God, which is able to understand the truth well, has a character like the Lord Jesus Christ, which is to love and serve and have the values of Christ that are applied in everyday life. AbstrakPendidikan dalam jemaat seringkali diwarnai dengan kurangnya keteladanan guru agama Kristen yang mengajar, membina dan mendidik mereka. Keteladanan ini berkaitan erat dengan keprofesionalan guru agama Kristen dalam membina jemaat secara konsisten, dinamis, efektif dan menyenangkan. Profesionalisme guru agama Kristen dalam mengajar dan membina jemaat menjadi kunci dalam membawa jemaat kepada kesempurnaan hidup seperti Kristus. Kehidupan dan karakter guru agama Kristen sangat mempengaruhi kehidupan dan karakter jemaat. Seorang guru agama Kristen yang mengajar dan membina jemaat harus memiliki pengalaman rohani dengan Tuhan, memiliki pengetahuan, keterampilan dan kemampuan menggunakan metode dalam proses pembelajarannya. Metode dalam membina jemaat salah satu keprofesionalan guru agama Kristen dalam membina jemaat yang sangat strategis. Sebab dengan kemampuan ini, maka dimungkinkan guru agama Kristen mampu membawa pengaruh terhadap kualitas dan kehidupan rohani jemaat. Dengan demikian, jemaat memiliki pengetahuan iman akan kebenaran Allah, yakni mampu memahami kebenaran dengan baik, memiliki karakter seperti Tuhan Yesus Kristus, yaitu mengasihi dan melayani serta memiliki nilai-nilai Kristus yang diterapkannya dalam hidup sehari-hari
