Published: April 2023

This paper examines how to outline and adopt innovative business models for the Smart Cities of the future. Smart Cities are intelligent and efficient communities and ecosystems employing digital technologies to respond a growing waste of resources, unsustainable environmental impact, and inefficiency in traditional processes. Considering the greatest benefits of Smart Cities on economies, societies, and environment, many countries have now introduced national Smart City projects in order to transform life, improve business operations and market competitiveness. However, despite growing interests towards Smart Cities, it remains still difficult to adopt this paradigm due to digital transformation, interaction strategies, social and cultural problems. Therefore, this paper aims to break down the barriers to these problems and support the literature and management to understand how to implement profitable business models for Smart Cities of the future. Specifically, we identify four main areas characterizing Smart Cities (i.e., Smart Mobility, Smart Living, Smart Energy, and Smart Public Ecosystems) where digital technologies have shown greater progress with large savings. For each area, multiple case studies have been discussed and Business Model Canvases have been developed for generalizing effective methodological approaches toward efficient implementation of Smart City paradigm. Results are threefold. As for digital transformation problems, we show how digital technologies (e.g., Cloud, IoT, Big Data and AI) are applied profitably through innovative business models; as for interaction strategies problems we indicate how to organize innovative ecosystems involving public and private actors to promote Smart Cities; as for social and cultural problems we delineate change management and communication practices useful to instill in all stakeholders a culture towards the Smart City. With these findings the paper aims at enriching scientific knowledge about the Smart City Paradigm by means of a business model perspective and to offer public administrations insightful guidelines for the transition toward Smart Cities.

Published: April 2023

The technology of flax harvesting depends on input impacts, including: flax harvester qualitative characteristics; working body parameters; indicators of working conditions; intervening variables reflecting the dynamic properties of the working bodies and the dynamics of the flax flow input. (Research purpose) To establish patterns and the degree of correlation between the qualitative operation indicators (pulling and deseeding quality, flax line stretching); design parameters; machine dynamic properties and harvesting conditions (height and density of flax stem, field surface, thickness and unevenness of flax straw, etc.). (Materials and methods) Based on system analysis, mathematical models of the technological process of flax harvesting were developed. Information models were introduced for examining the main flax harvesters. (Results and discussion) The paper shows that the most typical indicators of the flax harvester working conditions are the flax stem height l(t), centimeters; the seed pod area a(t), centimeters; and field surface roughness z(t), centimeters. It is found that the quality of operation is determined by the deseeding quality, percentages; the flax straw stretching, times; the location of its apical and root parts, centimeters. The estimated indicators are as follows: the pulling height h(t), centimeters, the vibrations of the combine in the longitudinal-vertical plane Q(t), degrees, the location of the apical part of the flax flaw in front of the stripper. (Conclusions) A hydraulic device was developed to adjust the pulling height from 10 to 40 centimeters, depending on the flax stem. An important reserve for increasing the deseeding quality is the change in the width of the deseeding zone of the Vk harvester, centimeters. For this purpose, a mechanism was created for moving the deseeder against the clamping conveyor, depending on the flax stem height l(t), centimeters.

This study aims to produce valid and practical PISA-based numerical problems in the context of the pandemic period and to find out the role of the questions in the form of potential effects on the mathematical literacy skills of secondary school students. This research uses developmental research design, which has 2 stages, namely preliminary and formative evaluation (self evaluation, expert review, one-to-one and small group validation, and field test). The participants in this study were students in Grade 8 who were under the age of 15 and different levels of skills. Data analysis was done descriptively by conducting observations, tests, interviews, and document analysis. The research was conducted face-to-face and via Zoom and WhatsApp Group (WAG) to produce valid and practical PISA-like arithmetic questions. Based on the students' responses, it can be stated that the questions presented are in the practical category because they can be completed quickly by students, they can be understood well by students, and they have the potential effect on students' mathematical literacy skills. In addition, there is a diversity of answers between one students and another according to the level of difficulty that is appropriate for Grade 8 students. This proves that a PISA-like numeration problem in the context of the religious day during a pandemic can help improve students' mathematical literacy.

Relativistic intraction of laser pulse with thermal electron plasma
Authors: J Vanchinkhuu 
Published: April 2023

The interaction of a short laser pulse (λp~L) with thermal fluid plasma in relativistic case is investigated in hydrodynamical approach. The one dimensional description of this process is developed and the fundamental equations describing the plasma quantities during the interaction are obtained. The wake generation by laser pulse is, also, investigated and the laser wake field in thermal plasma by a laser pulse is handled numerically. In weakly relativistic case, the wake potential propagating in snoidal wave form is obtained. While the wavelength of laser pulse is increased, the wavelength of plasma potential wave in thermal plasma is decreased compared to that in cold plasma. Also, due to the thermal motion, the amplitude of plasma wave is decreased.

The Use of the Hierarchical Method to Group the Countries of the European Union According to their Energy and Climate Policies Adopted on the Basis of Directives of the European Parliament
Authors: Zioło Monika , Luty Lidia 
Published: April 2023

Abstract

Subject and purpose of work
The European Union’s energy policy focuses mainly on three areas: reducing greenhouse gas emissions in the energy sector by increasing the use of RES, reducing emissions of harmful pollutants, and increasing the efficiency of the electricity used.
Sustainable energy use, on the other hand, is clearly associated with an increased use of renewable energy sources, which ensures energy security, as well as diversification of energy supplies that sustain and improve the quality of the environment.
The purpose of the paper is to present the diversity of the countries of the European Union in terms of the actions they take in the field of energy and climate policy resulting from the European Union directives.

Materials and methods
Based on the goals of energy policy presented in the EU directives a number of indicators were selected in order to describe the actions taken by EU member states. After a substantive and statistical verification, 6 variables were left. The use of the Ward’s method made it possible to create groups of countries that are similar in terms of their energy and climate policies.

Conclusions
The most favorable situation in terms of the effects of the climate and energy policy can be observed in the current leaders, that is in Sweden and Finland as well as in Estonia. Central European countries, mainly Poland, have high-emission economies, accompanied by low investment in modern environmentally friendly technologies. This is manifested, among others, in high concentrations of particulate matter, which contributes to poor air quality, categories in which Poland has some of the worst results in the entire EU.

Published: April 2023

Abstract

Subject and purpose of work
The aim of this paper is to make an analysis and evaluation of Lyme disease incidence, understood as a diagnosed farmers’ occupational disease.

Materials and methods
The analysis and an evaluation were made based on materials, data and information originating, among other things, from the following: The analysis and an evaluation were made based on materials, data and information originating, among other things, from the following: The Agricultural Social Insurance Fund, the Main Sanitary Inspectorate and the National Institute of Hygiene, official legal acts published in the Journal of Laws, industry literature, as well as works and publications of researchers dealing with Lyme disease.

Results
The results of this study indicate that Lyme disease is not only the main and dominant occupational disease of farmers, but also an infectious disease having a growing trend among Polish society. Every year, an increase in cases in which Lyme disease spirochete infection was found and diagnosed, is observed. This situation is affected not only by insufficient preventive measures, difficult and ineffective diagnostics, or low awareness of Lyme disease, but also by environmental factors and climate change.

Conclusions
Considering that the disease leads to numerous dangerous health-related consequences, while a protective vaccine has not yet been prepared, it seems extremely important to implement preventive measures and conduct education on prevention among farmers as well as other professional groups and the entire population.
An Analysis of the Public Distribution System in Rural Haryana, India
Authors: Devi Seema , Siwach Manoj 
Published: April 2023

Abstract

Subject and Purpose of the work
The present paper aims to analyze the functioning and coverage of the public distribution system in rural Haryana, India.

Materials and methods
For analyses, secondary data were taken from various government reports like the Economic Survey of Haryana, Economic Survey of India, Census of India, Food and Supply Department, Haryana, etc. The analyses were conducted using descriptive statistics.

Results
: The study’s findings revealed that the public distribution system facilitates 51.45 percent of the total rural population of Haryana. As Per the guidelines of the National Food Security Act (NFSA) 2013, 75 percent of the rural population should be covered by the States under the benefits of the public distribution system. The public distribution system operates in the State with a vast network of Fair Price Shops (FPS) and a well-organized structure. The study revealed that the ratio of the beneficiaries of PDS to the FPS in Haryana is quite satisfactory and meets the criteria fixed by the Food and Supply Department of India.

Conclusions
The State of Haryana does not meet the criteria of NFSA, 2013. One primary reason is that a large part of the population falls under the APL category, which has been excluded from the benefits of PDS after the implementation of NFSA, 2013.While the ratio of beneficiaries to FPS indicates the magnificent functioning of FPSs in the State.
Evaluation of the Crop Insurance Performance in Haryana
Authors: Sheoran Vandana , Kait Rohtas 
Published: April 2023

Abstract

Subject and purpose of the work
The purpose of the study is to evaluate the overall physical and financial performance of the crop insurance schemes in Haryana.

Materials and methods
The study was purely based on secondary data collected from the Department of Agriculture and Farmer Welfare Union of Haryana. The compound annual growth rate and the percentage method have been used to analyse the performance of Pradhan Mantri Fasal Bima Yojana.

Results
The compound annual growth rate of benefited farmers was higher in the Rabi crop (28%), and in the same way, the overall area covered (1.4%) was also higher in the Rabi crop. The non-loanee farmers adopted Pradhan Mantri Fasal Bima Yojana (PMFBY) without any kind of loan in any scheme such as the Kisan credit card. The growth rates of non-loanee farmers of Rabi and Kharif crops were observed at 143.2% and 184.3% which was highly satisfactory. Loanee farmers were already large in number since the commencement of PMFBY.

Conclusions
It was found that the parameters such as area covered, loanee, non-loanee farmers and the number of beneficiaries of Rabi and Kharif crops increased and had a significant effect on the farmer’s coverage over the years. Pradhan Mantri Fasal Bima Yojana gives a positive assurance to farmers. As the number of beneficiaries of this scheme increases and farmers have the assurance that if their crop is damaged due to natural calamities their claim will be settled, they will use a high-yielding variety of seeds, pesticides, herbicides, and new technology, thus production and productivity will increase. They play a vital role in the coverage of cultivated area and will ultimately decide to participate in crop insurance. Hence, this scheme has proved effective in maintaining the farmer’s interest in crop insurance and ensuring the timely settlement of claims, which has been the main driving force in retaining farmers under crop insurance.

Authors: Filipec Ondřej 
Published: April 2023

Abstract
Summary
In 2019 Czech Republic adopted a very ambitious national strategy on Artificial Intelligence (AI) with the vision of becoming a model example in Europe – a country of robots using safe and responsible AI. However, despite the adoption of many strategic documents, the Czech Republic remains at the level well comparable with other countries in the region. This article is providing an overview of the key documents, which marked the Czech way to AI and then confronting rather a positive image of the country with empirical findings, especially represented by the Government AI Readiness Index by Oxford Insights. The aim of the article is to provide a complex picture of the country in relation to Artificial intelligence, highlight most important milestones and discuss areas for the improvement. The author concludes that the Czech Republic is merely a „paper tiger“ with well-prepared background for AI, but just with a few areas of excellence.
