Purpose: With increasing digitalization, the debate on the direction of transformation in various sectors of the economy and their ability to keep up with the changes in this area is becoming increasingly complex. The energy industry is one of the key sectors in the economy, and as such it must follow trends and adapt to changing conditions. The aim of the paper is to diagnose and assess the level of progress in digital transformation among Polish energy sector enterprises. Design/methodology/approach: The research was conducted on a group of 110 entities, with a survey questionnaire. The gathered data was analyzed using descriptive statistics. Findings: Although the level of employing Industry 4.0 tools in Polish energy sector enterprises is at a low level, managers recognize the importance of following the path toward digital transformation. The awareness of particular digital transformation prerequisites differs depending on the phase of the digital transformation process. Research limitations/implications: Among the limitations of the research procedure, issues such as the single respondent design and the exclusion of micro entities from the research should be noted. However, the exclusion of micro entities from the analysis was intentional, and this area deserves the attention of researchers. The specificity of the functioning and organization of the activity of micro enterprises may distort the image of the sector. Referring to the single respondent design, it was assumed that in this phase of the research it is reasonable to collect individual opinions specific to a given enterprise. It would be worth extending the analysis by conducting in-depth interviews or attempting more in-depth research at the level of individual entities. Originality/value: This article contributes to the knowledge of the energy sector in Poland in the context of Industry 4.0. Keywords: digital transformation, digital strategy, digital transformation strategy, prerequisites for digital transformation, energy sector companies.

Published: January 2023

Purpose: The aim of this article is to present the results of research on needs and possibilities of implementing Lean Management concept at the university. Using the literature review and the results of empirical research, author proposes specific solutions (tools). Design/methodology/approach: The aim of the research was carried out on the basis of latest world literature review and empirical research conducted at a Polish university, the domain of which is practical education. The article is a case study with a proposal for the implementation of LM in a selected university. The research covered selected organizational units of universities. Findings: Recommendations for the use of selected Lean tools is the need to rationalize the activities undertaken in universities, including continuous improvement and flexibility of processes. There are economically justifiable actions to reduce waste and losses occurring in universities, as well as the integration of diversified and often non-cooperating organizational (functional) units. The proposals presented in this article may become an inspiration for universities that are thinking about implementing previously unused improvement tools. Research limitations/implications: Empirical research has been limited to one university, and the proposed methods and tools relate to selected functional areas. LM implementation requires prior analysis of the needs and capabilities of each organization. Practical implications: Due to the functioning of universities in an increasingly difficult to predict environment, they are forced to look for ways not only to survive, but above all to continuously improve the entire organization. The implemented rationalization and development measures should contribute to the improvement of the effectiveness and efficiency of management. Unpredictable changes concern the legal, socio-cultural, economic and economic environment, as well as the COVID-19 epidemic situation. These challenges are met by the concept of LM - as an inspiration and an opportunity to accelerate remedial and pro- development actions. Originality/value: The article is dedicated to people interested in the theory and practice of the LM concept. The use of the methods and tools proposed by the author in various functional areas of the university may bring about beneficial changes in the form of improvements in activities, time savings, as well as rationalization and greater efficiency of the implemented processes. Keywords: Lean Management, university, university management, organization improvement, efficiency.

Authors:   Jan Kochanowski University of Kielce, Flak Olaf
Published: January 2023

Purpose: The purpose of this paper is to present an answer to the research question of what could be the real impact of an artificial manager on the work of a team consisting of humans. Design/methodology/approach: In presenting the arguments for one way of proceeding AI-based management, a review of the recent literature in the field of artificial management and artificial leadership was used. The artificial manager used in the research was the result of a non-participating, long-term observation of a group of students working on an specific task, whose activity was recorded by online management tools called TransistorsHead.com. Findings: The real impact of the artificial manager on the human team members was very weak. Although team members were taking similar managerial actions as they were told by the system of TransistorsHead.com, they mixed the order and decreased or increased a period of the managerial actions. Research limitations/implications: Human members did not feel any emotional pressure on their behaviour from the artificial manager and they do not treat the system too seriously. What is interesting, the most obedient person was the appointed assistant of the artificial manager. The rest two members did not obey the rules. Practical implications: If we manage to create an artificial manager, it will be much harder to make it effective in working with human team members. The research on team management automation will impact upon the business by giving a chance of implementing artificial management. Social implications: even if we manage to create an artificial manager, it will be much harder to make it effective in working with human team members. Originality/value: There is a new research problem of replacing a human manager with an artificial manager which has to be solved in management sciences and managerial practice in the future. This paper contains findings which are the next step in solving a new research problem of replacing a human manager with an artificial manager. Keywords: artificial management, artificial leadership, virtual team, system of organizational terms. Category of the paper: Research paper, case study.

Telemedicine barriers and ways to overcome them.
Authors:   the Laboratory of Electronic Health, Institute of Digital Medicine, Sechenov University, Shaderkin I.A. ,   Moscow, Russia
Published: January 2023

The ongoing discussion of telemedicine suggests that there are barriers to the widespread adoption of telemedicine technologies in clinical practice. The article is the first to classify the barriers of the introduction of telemedicine technologies into practice. There are 4 main barriers: technological, legal, economic and methodological. At the end of the description of each barrier, ways to overcome them are given. The technological barrier includes: the inconvenience of using existing tools, poor integration of telemedicine platforms with existing medical information systems (MIS), Poor standardization of information exchange protocols between sources (devices), information systems from different manufacturers, a small amount and low quality of digitized information about the state of human health and others. In the legal barrier, it is prohibited to make a diagnosis and prescribe treatment when providing medical care using telemedicine technologies, and also there are requirements for the workplace of a doctor providing TM-consultation. Financial barriers are represented by the difficulties of financing telemedicine - the lack of compulsory medical insurance tariffs, the erroneous opinion that telemedicine should reduce healthcare costs or does not require separate financing at all. The lack of methodological support for telemedicine - clinical studies, publications, methodological and clinical recommendations, training courses and programs on telemedicine for students, leads to a low commitment of doctors to use telemedicine in their work. The process of implementing telemedicine technologies is unavoidable. However, there is no doubt that telemedicine will eventually become a familiar and indispensable tool in the hands of doctors. Sooner or later, even without our active participation, these barriers will be overcome.

The Effect of Investor Attention on Analyst’ Forecast
Authors:   Korea Accounting Information Association, Nam Giman , Jeon Keyongmin
Published: January 2023

[Purpose] This study examines whether there is an association between investor attention and analyst’s forecast.
[Methodology] This study was conducted by using Google searching volume index of Korea listed firms over the period from 2011 to 2017.
[Findings] The main findings as follow. First we find that the higher investor attention, the more significantly accuracy of analyst’s earnings forecast. Generally, analysts tend to respond in response to investors’ information needs, a higher investor attention in a particular entity also increases the information demand, which can be interpreted that analysts have incentives to provide more accurate earnings forecast to investors to maintain their reputation and compensation. Second, the higher investor attention, the less variance the analyst’s forecast error. This can be interred that as investor attention increases, analysts are tend to modify to the capital market’s consensus.
[Implications] Nowadays, despite of a growing number of study on the effect of investor attention in various fields, it is largely unexplored in accounting literature. This study extends to the literature by relating investor attention to analyst behavior such as earnings forecast.

The Impact of Reputational Expenses on Stock Price Informativeness
Authors:   Korea Accounting Information Association, Hwang Myung Cheol
Published: January 2023

[Purpose] This study analyzed the effect of reputation cost on stock price information. The cost of reputation is a direct or indirect cost borne by the general public to ensure that the corporate image is positively formed or to offset the negatively formed corporate image. If investors reflect their reputation cost expenditure information in future profit expectations, it will eventually affect the stock return and increase the future profit response coefficient. If reputation expenditure simply lowers the possibility of a tax audit by the tax authorities and alleviates the negative impact on corporate value caused by aggressive tax avoidance, as in the results of a study by Hwang Bo－young and Jeong Gyu－eon (2021), the future profit response coefficient will not decrease or show significance.
[Methodology] In order to achieve the research purpose, 17,687 annual－ samples of companies that meet the analysis conditions among companies registered in the KOSPI and KOSDAQ securities markets were conducted from 2002 to 2018. As for the reputation cost, as in Hwang Bo－young and Jeong Gyu－eon (2019), the residual excluding the portion used for marketing compared to sales was used.
[Findings] The empirical analysis results showed a significant positive (＋) relationship between reputation cost and stock price information. This means that the cost of reputation has a useful effect on stock price information. In response to these results, this researcher is considered to be the result of properly reflecting future profits on the current stock price by reducing uncertainty to investors’ spending on reputation costs.
[Implications] There are not many domestic empirical studies verifying the economic effect of reputation costs, and no empirical studies have been conducted on the effect of reputation costs on stock price information. This study has contributions and implications in that it analyzed whether the reputation cost provides useful information for investors to form expectations of future profits.

The number of work accidents in Indonesia and in the world is quite high, particularly in the mining sector. One of the factors that cause occupational accidents is poor sleep quality. Therefore good quality sleep is needed to reduce the risk of accidents. This study aims to describe the sleep quality of mining workers based on age, occupational category, and Body Mass Index (BMI). The research uses a descriptive design with a cross-sectional method. Data was collected from PT Borneo Indobara in 2020, as many as 120 workers. PSQI (Pittsburgh Sleep Quality Index) is used as an instrument. Then, sleep quality was reported in age, BMI, and occupational categories. The result shows that workers at PT Borneo Indobara are dominated by the age range of 21-40 years old (80%), working as operators (70.83%), and having normal BMI (56.67%). Most of the poor sleep quality is experienced by the worker with age range 18-20 years old (90.91%), working as a leader/officer (100%), and obesity as a BMI category (88.89%). Most of PT. Borneo Indobara employees have poor sleep quality based on the PSQI score, so that the management of PT. Borneo Indobara can use this research as employee evaluation data and can prepare treatment for the employees.

Published: January 2023

Drinking Water Depot (DWP) offers cheap and affordable drinking water, so it becomes an option for the society. However, the large number of public interest is not accompanied by qualified water quality. The test result by Bandung Public Health Office on DWP quality indicated that 55.22% were not eligible. The study aimed to determine the effective disinfection method to reduce microbiology in Reverse Osmosis (RO) and Non-RO methods. It was an analysis with a cross-sectional design. The population was all DWPs in Bandung and obtained 659 DWPs as samples. Sampling used two different tests and obtained 30 samples consisting of 30 DWP using RO and 30 Non-RO in average. Data analysis was done through univariate and bivariate using Wilcoxon Rank Sum test. The analysis result showed that polluted water raw quality was 48.33%; the bacteria reduction by RO method was 100% and Non-RO was 43.33%. The bivariate analysis result indicated that p-value was 0.033 which means that there was a difference between disinfection method using RO and Non-RO with the coliform presence. The RO disinfection is the best method which was able to be used by DWP owners. Thus, the society is suggested to choose DWP using RO disinfection method which verified by Public Health Department.

O objetivo deste trabalho foi monitorar a qualidade da água durante o inverno em pisciculturas de tanque escavado, tanque lonado e sistema de aquaponia no Assentamento Itamarati. Por meio de equipamentos portáveis para monitoramento de pH, temperatura, oxigênio dissolvido e saturação e kits de testes colorimétricos rápidos para averiguação da dureza, amônia tóxica e nitrito, foi possível observar a qualidade das águas de diferentes sistemas de cultivo de peixes. Observou-se que a temperatura da água de cultivo nos diferentes sistemas de produção apresentou uma amplitude entre 22,4 ºC e 12,9ºC. O pH manteve-se dentro neutralidade com pequenas variações, chegando a 6 e alcançando 9, para todos os sistemas analisados. O oxigênio dissolvido mg.L-1 e a saturação (%) apresentaram-se em concentrações baixas, menores do que a recomendação para cultivo de peixes neotropicais que é de 2 mg.L-1, contudo, não observou-se mudanças comportamentais e mortalidades nos cultivos. Para os parâmetros amônia e nitrito, estes se demonstram aceitáveis dentro do limite recomendado para não causar efeito adverso aos peixes. Durante os monitoramentos, os produtores foram capacitados para realizarem os procedimentos de análise da qualidade da água bem como práticas para minimizar possíveis impactos indesejáveis na piscicultura. Conclui-se que o monitoramento das variáveis físico e químicas da água de cultivo de peixes durante o inverno no Assentamento Itamarati é extremamente necessário para contribuir com a otimização da produção de peixes, aliada a difusão de conhecimentos e extensão da universidade aos produtores.

Authors: Luz João Alessandro da , Travassos Wilian Barbosa , Proença Marcelo Carlos de
Published: January 2023

O objetivo do artigo foi responder à seguinte questão: Qual o conhecimento de professores de matemática sobre a resolução de problemas no ensino de sistemas de equações do primeiro grau em sala de aula? Realizamos entrevistas semiestruturadas com sete professores de escolas públicas, individualmente e gravadas em áudio. De caráter descritivo e de natureza qualitativa, a análise das transcrições das falas deu-se pela Análise de Conteúdo. Os resultados mostraram que três professores apresentaram entendimento adequado sobre problema e sobre como resolver um problema, de modo que suas aulas se baseiam no ensino via resolução de problemas. Por outro lado, quatro professores não apresentaram entendimentos adequados, focando apenas nas características de exercícios, de modo que suas aulas não seguiam o ensinar via resolução de problemas. Concluímos que é necessário o envolvimento desses professores em formação continuada para (re)construírem seus conhecimentos sobre como abordar a resolução de problemas em sala de aula.

CİNSİYET KİMLİĞİNİN TÜKETİCİ DAVRANIŞLARINA ETKİSİNDE TOPLUMSAL ROL ALGISININ ARACILIK ROLÜ
Authors: DEMİRAL Barış Yiğit , ÖZ Fuat
Published: January 2023

Pazarlama araştırmalarında biyolojik cinsiyet önemli değişkenlerden bir tanesidir. Ancak günümüzün rekabet ortamında pazarlama kararları ve stratejileri için biyolojik cinsiyetin tek başına yeterli olmadığı ve kişisel karakteristik özelliklerin, toplum beklentilerinin ve kültürün etkisinde oluşan psikoloji kaynaklı cinsiyet kimliğinin de önemli etkisinin olduğu değerlendirilmektedir. Bu çalışmada, tüketici davranışlarında cinsiyet kimliğine toplumsal rol algısının, aracılık rol etkisinin var olup-olmadığı araştırılmıştır. Baron ve Kenny ölçeği esas alınarak araştırmanın hipotezleri oluşturulmuş ve analizleri yapılmıştır. Araştırma Afyonkarahisar ilinde kolayda örnekleme yöntemi ve yüz yüze anket metoduyla 2021 yılı içerisinde 438 tüketicinin katılımıyla tamamlanmıştır. Fakat hatalı ve eksik veriler nedeniyle iki katılımcının verileri çıkartılarak 436 katılımcının verileri vasıtasıyla analizler yapılmıştır. Bağımlı değişken olan tüketici davranışı üzerinde bağımsız değişken olan cinsiyet kimliğinin etkisinde aracı değişken toplumsal rol algısının aracılık rolünün olduğu belirlenmiştir. Tüketici davranışları üzerine çalışan bilim insanlarının ve pazarlama departmanlarının çalışmalarında sadece cinsiyet değişkeninin yetersiz olacağı ve cinsiyet kimliği değişkenini de araştırmaları gerektiği sonucuna ulaşılmıştır. Ayrıca cinsiyet kimliği değişkeni incelenirken toplumsal rol algısının da aracı değişken olarak değerlendirilmesinin ve aracılık etkisi olabilecek benzer değişkenlerin de araştırılması ve incelenmesi gerektiği sonucuna ulaşılmıştır.
XVI. YÜZYILDAN GÜNÜMÜZE TOSYA ŞEHRİ VE KIRSALINDA SU DEĞİRMENLERİ: TESPİT, SÜREÇ VE DEĞİŞİM
Authors: YAZGAN Ziya Çağrı , YİĞİT İlker
Published: January 2023

Sanayi Devrimi öncesi geleneksel tarım toplumları için hayati öneme sahip su değirmenleri bugün Anadolu’nun çoğu yerinde beşeri faktörler ve doğal süreçlerin etkisiyle işlevini yitirmiş ve harap olmuş birer kültürel miras unsurudur. Ancak su değirmenleri mimari yapısı, teknolojisi ve sosyo-ekonomik hayata etkisi itibariyle tarihin derinliklerine uzanan kadim bir geleneğin ürünüdür. Dolayısıyla su değirmenleri sahip olduğu mimari, teknolojik, mühendislik, coğrafi, kültürel vb. değerleri göz önüne alındığında farklı disiplinlerce çeşitli yönleriyle incelenmesi gerekir. Bu noktadan hareketle eldeki çalışmada Tosya’da bulunan su değirmenlerinin XVI. yüzyıldan günümüze kullanım şekilleri, mekânsal örüntüleri, zaman içerisinde yaşadığı değişim ve dönüşümün ortaya konulması amaçlanmıştır. Çalışma için gerekli veri setleri Tahrir (1579) ve Temettuat (1845) defterlerinden temin edilmiştir. Yapılan araştırmalar neticesinde Tosya’da XVI. yüzyıl içerisinde 49, XIX. yüzyıla gelindiğinde 36 değirmenin mevcut olduğu bilgisine ulaşılmıştır. Günümüzde Tosya şehri ve kırsalında yapısal ve biçimsel özelliklerini koruyan fakat aktif olarak kullanılmayan toplamda üç su değirmeni bulunmaktadır. Tosya şehri ve çevresinde, teknolojik gelişmeler, kırsal nüfusun azalışı, ulaşım şartlarının iyileşmesi ve değişen iklim koşullarına bağlı olarak su değirmenlerinin işlevini yitirdiği anlaşılmaktadır. Bu bağlamda araştırma sahasında bulunan su değirmenlerinin kültürel miras kapsamında değerlendirilip gerekli yapısal tadilat/tamiratın yapılması ve yeni bir işlev tanımlanması önem arz etmektedir. Ayrıca söz konusu unsurların gelecek nesillere aktarılabilmesi için sürdürülebilir ve bütüncül bir koruma stratejisi ile hareket edilmesinin bir zorunluluk olduğu değerlendirilmektedir.

Suppliers play an important role as suppliers of production raw materials, making companies must choose suppliers correctly. This paper discusses the best supplier selection to avoid financial and non-financial losses This paper uses four criteria for determining the best supplier, such as price, lead time, payment terms, and quality & service. A reasonable price following initial planning is always expected by the customers. Lead time is an essential consideration to ensure on-time delivery. Failure to perform on-time delivery will direct in poor payment terms. Besides, any products that do not meet quality standards will always lead to waste. Analytical Hierarchy Process (AHP) and Technique Order Preference by Similarity to Ideal Solution (TOPSIS) are used to select and determine the best supplier for the company. Pairwise comparisons are performed by making comparisons between each criterion and the alternatives made at each level of the hierarchy in pairs to get the value of the importance of the elements in the form of a qualitative opinion. The weight values for price, lead time, payment terms, and quality and service criteria are 0.0709, 0.1409, 0.2682, and 0.5200, respectively. According to AHP, alternative weight values in each criterion are 0.3899, 0.3063, and 0.3038, namely supplier A (rank 1), supplier B (rank 2), and supplier C (rank 3), respectively. However, the results of supplier selection using the TOPSIS method are supplier B (rank 1), supplier C (rank 2), and supplier A (rank 3) with values of 518.4025, 469.2017, and 412.3928, respectively.

Published: January 2023

El papel desempeñado por las asociaciones en Marruecos siempre ha estado ligado al contexto político y socioeconómico del país. La puesta en marcha de la Iniciativa Nacional para el Desarrollo Humano (INDH) supone un impulso, un revulsivo para el tejido asociativo marroquí. Este trabajo analiza la distribución de las asociaciones en la provincia de Chefchaouen así como su participación en la INDH a través de sus proyectos en el periodo 2011-2018. Se realiza un primer análisis cuantitativo a partir de las inversiones realizadas y de las subvenciones recibidas que se complementa con otro de carácter cualitativo a partir de las entrevistas a sus responsables. Los datos revelan que la distribución de las asociaciones, inversiones y subvenciones en el marco de esta iniciativa presenta una gran disparidad, beneficiando más a los territorios menos pobres. Asimismo, se constata que el dinero de la INDH ha sido fundamental para la realización de estos proyectos y el logro de sus objetivos, siendo necesario modificar su reparto territorial en favor de los territorios más pobres.
