Utilization of technology can provide convenience in learning for educators and students whom have limited distance and time, to continue to carry out learning activities. One of them is through e-learning. The development and development of e-learning is currently so easy with a learning management system software called Moodle. The purpose of this study was to produce Moodle-based LMS learning media with valid and practical criteria at the Design, Development, and Formative stages. This study uses the Research and Development (R&D) method and the McKenney development model. The Needs and Context Analysis stage was carried out by collecting data through questionnaires, unstructured interviews, literature studies, and field surveys. In the Design, Development, and Formative Evaluation stages, the design framework and features of learning media are designed. The features developed are topics format and enrolled users. The data processing of the needs and practicality questionnaire is carried out using a percentage score, and validity using the validity criterion value. From the results of the needs and context analysis, a learning media is needed that can make students use more than one sense and make students actively participate in learning. The results showed that the validation value was 0.85 with valid criteria and the practicality test obtained a value of 82.1% with practical criteria. Therefore, the Moodle-based LMS learning media that was developed met the valid and practical criteria.
Some aspects for constitutional and legal liability of bodies and officials of state power in Ukraine
Authors: Kravtsova Z.
Published: December 2022

The article analyzes certain aspects of constitutional and legal responsibility. It is noted that on the agenda, Ukraine is tasked with adapting the legislation of Ukraine to the legislation of the EU as much as possible. It is emphasized that at the constitutional level, constitutional-legal responsibility is not recognized as an independent type of legal responsibility, due to which there is a lack of a regulatory-legal basis and an effective mechanism for the implementation of constitutional-legal responsibility, and as a result, a significant number of violations of the Constitution and Laws of Ukraine by public authorities remains without the necessary response. It is noted that the current constitutional legislation of Ukraine establishes separate grounds for constitutional liability and defines specific constitutional sanctions, but it remains informalized by law. The content and components of legal responsibility, including constitutional and legal responsibility, are clarified. It was concluded that, based on the legal nature of legal responsibility, the latter should provide for negative consequences for subjects who violate, ignore, or do not fulfill legal prescriptions. Attention is focused on the problem of understanding and consolidation of constitutional, legal and political responsibility. It is proposed to provide for a pragmatic combination of the implementation of constitutional and legal and political responsibility at the legislative level. It was determined that under the constitutional and legal responsibility of bodies and officials of state power, it is necessary to understand a separate type of legal responsibility, which has a political and legal nature, occurs when the specified subjects commit a constitutional and legal delict and consists in unfavorable, negative consequences, provided for by the norms constitutional law. It is noted that clear observance of the grounds for bringing to constitutional and legal responsibility will serve as a basis for ensuring democracy, rule of law, legality, constitutionality, ensuring human rights, people's power in constitutional and legal relations. It was concluded that a significant drawback of this issue is the actual lack of constitutional regulation of constitutional and legal responsibility. During the disclosure of the issue of constitutional and legal responsibility, strong integrative links of constitutional and legal responsibility with other types of legal responsibility were revealed.
Constitutional justice as an element of the law protection function of the EU States
Authors: Fomina S.
Published: December 2022

Traditionally, the main function of the body of constitutional jurisdiction is the function of constitutional control, but the human rights function, although not a classic one, is equally important.

The human rights protection function of the body of constitutional jurisdiction in practice is expressed in ensuring the possibility of turning to such a body of a natural or legal person whose rights have been violated, as is usually the case in the case of using all possible means of protection.

In this article, the experience of applying the human rights function by the bodies of constitutional jurisdiction is considered on the example of the activities of the constitutional courts of the countries of Central Europe and at the same time of the countries of the European Union - Poland, Hungary, Slovakia and the Czech Republic. This experience is valuable for Ukraine, since the constitutional crisis recently affected the Constitutional Court of Ukraine, as well as in view of the active European integration processes in Ukraine and the need for its post-war reconstruction, which is not possible without the coordinated functioning of all state authorities.

 The article examines the experience of reforming the body of constitutional jurisdiction, the legislator's view on the powers of such a body, and vivid examples from human rights practice. A conclusion was made about the formation of transnational constitutionalism by such states, similar to the principles of the European Union, the application of unified, developed principles of proportionality when assessing the balance in the conflict of two or more fundamental human rights.
The concept of the principle of procedural economy in civil proceedings
Authors: Muzychko S.
Published: December 2022

The article is devoted to revealing the concept and content of the principle of procedural economy as a component of civil justice. An analysis of national and European judicial practice in civil proceedings was carried out.

The article examines and analyzes certain aspects of procedural economy in the civil process component, which is important for increasing the efficiency of the latter. Methods of abuse of procedural rights in civil proceedings are analyzed.

Civilians consider the issue of including the principle of procedural economy as a separate provision to the civil procedure code controversial, however, the procedural law enshrines the elements of procedural economy in its prescriptions.

Achieving a balance between the rational use of resources and making fair decisions is one of the main tasks of the judiciary. Ensuring the effectiveness of the principle of procedural economy is implemented in the interrelationship of saving time, actions and funds, which is inseparable, and the loss or reduction of the value of at least one of them will negatively affect the effectiveness of civil proceedings in general.

It was determined that the consideration and resolution of the case conditions the means of ensuring the achievement of a law-enforceable result, which should be characterized by efficiency, which is reflected at the national level through the requirements of timeliness, impartiality and justice. The effectiveness of the principle of procedural economy and its material and legal value are highlighted. Excessive duration of civil cases can have negative consequences for both the participants in the process and the judges, as well as for society and the state as a whole. The speed of judicial proceedings is a necessary condition for achieving the objective truth. The court decision must correspond to the actual circumstances, and it is easier to establish them the less time has passed since their occurrence. In addition, the need to protect a person's right arises due to its violation, which puts it in a difficult position, leads to complications and further legal uncertainty. Attention is paid to the analysis of the essence of saving the process and methods of its implementation are determined.

It is proposed to include the principle of procedural economy in the list of principles of civil justice at the level of legislative changes to the national legislation, which will definitely have a positive effect on the further development of the civil process.

Authors: Sydorenko N.
Published: December 2022

The article studies actual problems of legal regulation of prosecutor’s participation in civil procedure, analyses court practice of national courts and European Court of Human Rights. The author points out at the collisions of current legislation of Ukraine regarding legal regulation of prosecutor’s participation in court procedure. The article analyses special decisions of European Court of Human Rights in the context of prosecutor’s protection of  person’s interests providing civil proceedings and necessity to follow the principle of equality of all participants in the trial and ensuring  fair consideration and resolution of civil cases. In the article a special attention is paid to issues of ensuring of procedural balance of equality of all participants in the trial according to the provisions of Civil Procedure Code Of Ukraine taking into consideration that participants have no right to declare recusal of the prosecutor, insufficient level of knowledge in the sphere of law in comparison with prosecutor and extended amount of prosecutor’s possibilities concerning collection and providing evidences to the court in civil cases, and issue of enforcement  of separate court ruling in the case of improper performance of professional obligations or other violation of the law by prosecutor. The author emphasizes that legally defined list of persons, whose interests can be protected in civil procedure by prosecutor doesn’t contain adult capable persons who may require such defense due to old age or disability. The author studies conflicts between provisions of the Law of Ukraine on the Public Prosecutor’s Office and Civil Procedure Code of Ukraine regarding intervention in a case, in which the proceedings have been initiated upon a claim of another person. The author comes to conclusion about expediency of legal universalization and harmonization, consideration of European lawmaking and court institute’s recommendations and consequently amendments to current provisions of the Law of Ukraine on the Public Prosecutor’s Office and Civil Procedure Code of Ukraine in order to facilitate enforcement of compliance with the principles of civil proceedings - equality of all participants in the trial under the law and before the court, adversarial character of the parties and supporting of fair consideration of civil cases with the participation of prosecutor.
Legal regulation of copyright in the ukrainian lands of the Russian Empire
Authors: Michnevisch L.
Published: December 2022

The article explores the genesis of the legislative consolidation of copyright law in the Ukrainian lands that were a part of the Russian Empire. The thesis is substantiated that the legal regulation of copyright law in these territories was formed under the influence of both European legal traditions and imperial legislative norms. It was revealed that the formation of the idea of authorship in Russia occurred much later than in European countries. The reasons were the long-term attachment of copyright law to censorship legislation and the late commercialization of publishing. It was revealed that the right to literary property was first established in Russian legislation. The literary property was considered as acquired property. Later on, the right of musical and artistic property received legal protection. The thesis has proved that the proprietary concept of copyright law in Russia has been dominant for a long time. At the end of the 19th century, the question of the legal nature of copyright law became relevant, which ultimately formed the idea of separating property and non-property interests of the author in Russian law. Therefore, the evolution of copyright law in the Russian Empire is characterized by a transition from the protection of the interest of the distributor of the work to the protection of the interest of the author.

It was revealed that in the 19th century Russia was in certain isolation and did not participate in the most important international agreements on the protection of intellectual property, except for two bilateral conventions with France and Belgium on the protection of copyright law. It was established that the copyright law in 1911 brought the legal regulation of copyright law in the Russian Empire to the European level and introduced many progressive novellas that positively impacted the further development of the institution of copyright law.

All-Russian legislation of copyright law was also extended to Ukrainian-controlled lands. However, it is indicated that Russia introduced rather strict censorship rules for Ukrainian-language publications to their complete ban, therefore there is no need to talk about the protection of copyrights law of Ukrainian authors.
The nature of obligation in the views of J. St. Mill and J. Austin
Authors: Popovych T.
Published: December 2022

The article is devoted to the analysis of the nature of obligations in the light of the views of certain thinkers of utilitarianism and positivism, namely: J.St. Mill and J. Austin. The author emphasizes that the utilitarian vision of J.St. Mill, first of all, connects obligation not so much with the desire to maximize good in society, but with minimizing harm from the actions of individuals. The obligation is characterized by compulsion to certain socially useful actions, for failure of which the individual may be held liable. At the same time, he is obliged to refrain from everything that harms others. Therefore, an obligation is what can be demanded from a person. According to the thinker, the sphere of moral obligations includes rules that determine exactly those obligations that society has approved for fulfillment. The criterion of the correctness of our actions is the extent to which they contribute to the achievement of happiness - the highest goal of human aspirations. The motives for fulfilling moral obligations are the so-called external and internal moral sanctions. According to J. St. Mill, justice involves not only the obligation to do right (and not to do wrong), but also the demand of certain persons regarding what they have a moral right to do.

At the same time, the teaching of J. Austin (the so-called theory of orders) regulates a strict concept of obligations that permeates the entire legal system. The obligation is embodied in an order, implemented through the law, provided with a sanction. The sanction is a necessary element of the law, in its absence the binding effect of legal norms loses its force. The English scientist somewhat radicalizes the doctrine of obligations: the existence of rights is possible only due to the existence of obligations. The fulfillment of a obligation is the fulfillment of the will of a person (God, a sovereign or a private individual) who possesses power (supremacy). It should be noted that only in the context of religious obligations, which derive from divine laws, the scientist talks about the motivation of fulfilling obligations - the greatest happiness for all people. In the remaining cases, the implementation of the orders of superiors by inferiors is assumed to be uncompromising and does not take into account the will of the individual. Society becomes a community of people in which obligation reigns, thanks to which development and provision of good for all is possible.
Lima no respondía. El fracaso del plan insurreccional planteado en México explicado en carta de Víctor Raúl Haya de la Torre a Wilfredo Rozas, fechada el 22 de septiembre de 1929
Authors: Parodi Revoredo Daniel
Published: December 2022

La presente pesquisa trata del Plan insurreccional planteado en México por el líder del APRA Víctor Raúl Haya de la Torre en 1928, el que enfrentó tenaz oposición de José Carlos Mariátegui La Chira. El Plan Insurreccional no llegó a realizarse debido a que Mariátegui inició una áspera polémica ideológica contra Haya que distrajo a las demás células apristas peruanas e impidieron que se sumasen a la revolución. Nuestra tesis central es que Mariátegui vio amenazada su posición de líder de la izquierda peruana, obtenida tras la fundación de la revista Amauta en 1926, pues el Plan de Haya proponía la creación del Partido Nacionalista Libertador, con sede central en México. Este planteamiento relegaba a un segundo plano a Mariátegui y el grupo de Lima, razón por la cual iniciaron un abierto enfrentamiento contra el APRA, que dividió a la izquierda peruana y frustró el Plan insurreccional.
Apariencias y cultura material en el Madrid moderno. Prácticas identitarias y de consumo de los artesanos textiles de la Corte (siglo XVII)
Authors: Romero González Álvaro
Published: December 2022

Este trabajo analiza la identidad de los artesanos de la Real Cámara durante el siglo XVII a través del sentido de las apariencias. Las disposiciones regias propulsaron su distinción desde la jura del oficio, a lo que se añadía la búsqueda de diferenciación individual y familiar a partir de la indumentaria y los interiores domésticos. La identidad que adquirían como criados reales les empujaba a demostrar, desde el consumo material, su condición en la sociedad del Madrid cortesano.
Comerciantes “alemanes” en la ciudad de Valladolid (1760-1850)
Authors: Miguel López Isabel
Published: December 2022

La investigación sobre los comerciantes “alemanes” en la ciudad de Valladolid pretende desentrañar su papel en la dinámica socioeconómica de la misma y su participación tanto en el mercado interior como en el internacional. Para ello se ha recurrido a la información de los protocolos notariales junto a otras fuentes complementarias. De este análisis se ha desprendido la exclusividad de su origen bohemio con el que siguieron manteniendo contacto. Además, sus empresas, una de ellas con dos sedes, fueron medianas y actuaron en los circuitos comerciales de la mitad norte peninsular y en los europeos, a través de los puertos de Santander y Bilbao.

La confianza como factor clave en el desarrollo de clústeres turísticos
Authors: De Luca Anabella
Published: December 2022

El presente trabajo tiene como fin estudiar la importancia de la confianza como factor fundamental (Gómez Díaz, 2017) en la gestación de clústeres, aplicado al sector de turismo de reuniones de la ciudad de Posadas, provincia de Misiones, Argentina. Se busca identificar la existencia o no de dicho factor necesario para el desarrollo de estas estructuras que permiten incrementar la competitividad de la actividad. Este artículo, elaborado a partir de métodos cualitativos, concluye que, si bien el sector está consolidado porque posee infraestructura, demanda, proveedores, y un fuerte apoyo gubernamental, aún las relaciones sociales entre los actores son pasajeras y cambiantes, y están marcadas por cuestiones personales y comportamientos individualistas. Esto genera una intensa competencia local y la ausencia de lealtad entre los actores, dificultando la creación de un clúster. Si bien hay indicios de cooperación entre dichos actores, esta es selectiva por lo que podemos afirmar que no hay confianza en el sector estudiado.

Published: December 2022

Spectrum map is the foundation of spectrum resource management, security governance and spectrum warfare. Aiming at the problem that the traditional spectrum mapping is limited to two-dimensional space, a three-dimensional spectrum data acquisition and mapping system architecture for the integration of space, sky and earth is presented, and a spectrum map reconstruction scheme driven by propagation model is proposed, which can achieve high-precision three-dimensional spectrum map rendering under the condition of sparse sampling. The spectrum map reconstructed by this method in the case of single radiation source and multiple radiation sources is in good agreement with the theoretical results based on ray tracing method. In addition, the measured results of typical scenes further verify the feasibility of this method.
Some thoughts on deep learning empowering cartography
Authors: Ai Tinghua
Published: December 2022

Cartography includes two major tasks: map making and map application, which is inextricably linked to artificial intelligence technology. The cartographic expert system experienced the intelligent expression of symbolism. After the spatial optimization decision of behaviorism intelligent expression, cartography faces the combination of deep learning under connectionism to improve the intelligent level of cartography. This paper discusses three problems about the proposition of “deep learning + cartography”. One is the consistency between the deep learning method and the map space problem solving strategy, based on gradient descent, local correlation, feature reduction and non-linear nature that answer the feasibility of the combination of “deep learning + cartography”; the second is to analyze the challenges faced by the combination of cartography from its unique disciplinary characteristics and technical environment, involving the non-standard organization of map data, professional requirements for sample establishment, the integration of geometric and geographical features, as well as the inherent spatial scale of the map; thirdly, the entry points and specific methods for integrating map making and map application into deep learning are discussed respectively.

Published: December 2022

Thoracic duct drainage (TDD) is gaining renewed interest, largely due to accumulation of evidence supporting the gut-lymph model, where toxic mesenteric lymph from the intestine contributes to development of multi-organ failure in acute and critical illness (ACI). Advances in minimally invasive TDD have added to this growing interest. The English TDD literature has been previously reviewed, but the more extensive Eastern European literature has not been available to English readers. Therefore, we undertook a systematic search of Eastern European human TDD studies using Scopus and PubMed databases and Russian language websites. Indications for TDD, clinical outcomes, and complications were re- viewed. 113 studies, published between 1965 and 2015, were reviewed. The most common indications for TDD were hepatic failure, acute pancreatitis, and peritonitis. It was often used late and when other treatment options had been exhausted. Human TDD appeared safe and probably effective, especially when combined with lymphosorption. The benefit appeared to correlate with the volume of lymph drained. A randomized controlled trial (and some case-control studies) showed reduced mortality in patients with ACI with TDD. Other benefits included rapid normalization of blood parameters and decreased organ edema. This review provides further support for the gut-lymph model and justification for high quality randomized controlled trials of TDD in ACI. It also highlights other potential indications for TDD, such as bridging patients with liver failure to surgery or transplant.

Published: December 2022

We have studied the lymphatic phenotypes of 2 mutations, known to cause abnormalities of lymphatics in humans, in mice. The Cx47 R260C mutation (variably penetrant in humans heterozygous for it and causing limb lymphedema) had an adult mouse phenotype of hyperplasia and increased lymph nodes only in homozygous condition but we did not find any anatomical phenotype in day 16.5 homozygous embryos. Mice harboring the Sos1 mutation E846K (causing Noonan's 4 in man which occasionally shows lymphatic dysplasia) had no adult heterozygous phenotype in lymphatic vessel appearance and drainage (homozygotes are early embryonic lethals) while day 16.5 heterozygous embryos also had no detectable anatomical phenotype.
A journey from resect to respect to restore: aiming at optimal physiological surgical mitral valve repair
Authors: Mastro Florinda , Angelini Annalisa , D’Onofrio Augusto , Gerosa Gino
Published: December 2022

The concept of ‘repairing’ a degenerated mitral valve in order to restore the native competence means achieving the best physiological result coupled with the least invasive approach: this represents an interesting challenge for cardiac surgeons. The evolution of cardiac surgery through the years has involved techniques and technologies in every field of interest.

From ‘resect’, to ‘respect’, to ‘restore’: the micro-invasive approach based on Neochord implant implies a transapical beating heart surgery which is based on the concept of implanting artificial chordae, preserving the physiological dynamics of the mitral annulus and avoiding the disadvantages of cardiopulmonary bypass and cardioplegic arrest of the heart.
Dynamics of the African swine fever spread in Poland
Authors: Bocian Łukasz , Frant Maciej , Ziętek-Barszcz Anna , Niemczuk Krzysztof , Szczotka-Bochniarz Anna
Published: December 2022

Introduction

African swine fever (ASF) is a lethal haemorrhagic disease of Suidae, present in Poland since 2014. The natural reservoir of ASF in Europe is the wild boar (Sus scrofa); however, human activity facilitates long-distance introductions of the disease. In ASF control it is important to identify areas at increased risk of infection. Such identification and estimation of the disease’s progress and subsequent spread will help to identify the specific preventive action needs in given zones. Serving this purpose, this study is a spatial and statistical analysis of ASF spread through noted outbreak data.

Material and Methods

The spatial-temporal analysis was conducted on the basis of data including the time and location of all ASF outbreaks both in wild boars and domestic pigs in Poland in 2014–2021.

Results

The analysis indicates possible routes and directions for further ASF spread in Poland, estimates the annual increase of the affected area (approx. 25,000 km2 every year since 2017) and marks trends. The strong method-independent correlation between the year and the surface area affected by African swine fever indicated a near-linear generalised trend.

Conclusion

Given the growth trend, we can expect ASF to expand further into new territories of the country; however, it is important to realise that there is still a significant area to protect, because 60% of Poland remains ASF-free.
Effect of immunomodulation in turkeys infected with haemorrhagic enteritis virus on the percentage of CD4+ and CD8α+ T lymphocyte subpopulations synthesising IFN-γ
Authors: Tykałowski Bartłomiej , Koncicki Andrzej
Published: December 2022

Introduction

Haemorrhagic enteritis virus (HEV) is a common turkey pathogen which suppresses the immune function. The immunosuppressive potential of both field and vaccine strains of HEV makes it necessary to seek substances which can limit or prevent this phenomenon. The aim of the presented work was to investigate the effect of two immunomodulators in the immune response of HEV-infected turkeys. The immunomodulators were synthetic methisoprinol and a natural preparation containing 34.2% β-glucans (β-1,3/1,6) and 12% mannan oligosaccharides (MOS).

Material and Methods

The synthetic immunomodulator was administered to female Big 6 turkey chicks at a dose of 200 mg/kg b.w. in drinking water i) for 3 days before, ii) for 5 days after, or iii) for 3 days before, on the day of infection, and for 5 days after experimental HEV infection in turkeys. The natural counterpart was also given to female Big 6 turkey chicks at a dose of 500 g/tonne of feed i) for 14 days before, ii) for 5 days after, or iii) for 14 days before, on the day of infection, and for 5 days after infection. Their effect was evaluated on the synthesis of interferon gamma (IFN-γ) by splenic CD4+ and CD8α+ T cells in response to mitogen stimulation in vitro. Samples were taken 3, 5 and 7 days after infection and analysed by intracellular cytokine staining assay.

Results

Methisoprinol was shown to increase the CD4+IFN-γ+ and CD8α+IFN-γ+ T cell count in these birds over the same cell count in control turkeys. A similar effect was obtained in turkeys that received the natural immunomodulator.

Conclusion

The evaluated immunomodulators may be used to attenuate the effects of immunosuppression in HEV-infected turkeys.
Health risk assessment in the vicinity of a copper smelter: particulate matter collected on a spider web
Authors: Trzyna Agnieszka , Rybak Justyna , Bartz Wojciech , Górka Maciej
Published: December 2022

We used spider webs as a particulate matter (PM) sampler to assess the possible health risk to the inhabitants of Legnica city (Poland). We aimed to find out if it is a useful material and could provide reliable information. We selected two spider families (Agelenidae and Linyphiidae) whose webs structure enhances the PM accumulation. The collected particles were analysed using a Scanning Electron Microscope equipped with Energy Dispersive X-Ray (SEM-EDX) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) which provided morphological and chemical information and allowed to indicate possible sources of pollution. The results showed that PM10, the fraction of particles smaller than 10 µm, was dominated by the particles of natural origin, while fine fractions were composed of diverse anthropogenic particles, whose origin can be connected with the activity of the copper smelter and in smaller quantity with the road traffic. The carcinogenic and non-carcinogenic health risk was assessed for these pathways: inhalation, ingestion, and dermal, for children and adults. The non-carcinogenic risk was very high (Hazard Index: HI > 1) both for children (Cu, Ni, Pb, Cd) and adults (Cu, As, Pb, Cd). Moreover, high carcinogenic risk (>10-4) was found in most of the sampling points. The study shows that spider webs are useful in biomonitoring of PM and can also be used for health risk assessment. In the studied region, it was found that the possible negative impact of air pollution on human health exists.
Dependence of Housing Real Estate Prices on Inflation as One of the Most Important Factors: Poland’s Case
Authors: Melnychenko Oleksandr , Osadcha Tetiana , Kovalyov Anatoliy , Matskul Valerii
Published: December 2022

The study aimed to examine the impact of inflation on the real estate market using Polish panel data for the last 13 years. It is based on a panel model, where price changes of one square meter of housing are determined as a function in changes of inflation, the central bank’s base rate, dwellings built, as well as new mortgage loans. The quarterly dynamics of the average price of 1 square meter of housing in Poland’s eight largest cities in the 2009-2021 period was studied. This price was modeled and predicted using one of the Box-Jenkins time series models: the Holt-Winter model of exponential smoothing with a damped trend. The forecasting results showed a small (up to 4%) relative error in comparison with the actual data. In addition, the moment (2017) of the price trend change was found. Therefore, piecewise linear regressions with high regression coefficients were used when modeling the impact of inflation changes on the real estate market indicators under consideration. The results obtained provide valuable insight into the relationship of real estate market indicators, allowing consumers to predict available options and make decisions in accordance with their preferences.
Solar Energy Based Charging for Electric Vehicles at Fuel Stations
Authors: Valdmanis Gunārs , Rieksta Madara , Luksta Ilze , Bazbauers Gatis
Published: December 2022

The electricity used for charging electric vehicles (EV) must be produced from renewable energy sources to make EV carbon neutral. Solar PV panels installed at fuel stations can provide a noticeable fraction of charging electricity for EV also in countries located in the Northern region. The study aims to assess the potential dynamics of that fraction given a certain growth rate of the number of EV. System dynamics modelling is used as the method and Latvia is chosen as the case. The model contains parts for the calculation of the number of EV, dynamics of charging units and PV panels at fuel stations as well as in other places, the share of PV-produced power, and the resulting reduction of CO2 emissions. Economic factors, i.e. subsidies for EV purchase, investments, and costs of charging are considered in the model. Assessment is based on sensitivity analysis. Results show that the subsidies for the purchase of EV and the price of new EV play a decisive role in the growth rate of EV and the resulting reduction of CO2 emissions from light-duty vehicles.

Penyakit ginjal kronis atau Chronic Kidney Disease (CKD) adalah gangguan pada ginjal yang mengakibatkan ginjal tidak dapat melakukan fungsinya dengan baik karena turunnya kinerja organ ginjal. Klasifikasi adalah teknik data mining yang dapat digunakan dalam mendiagnosis penyakit ginjal kronis. Pada penelitian ini, klasifikasi dilakukan dengan menggunakan algoritma C4.5. K-Means Clustering digunakan untuk mendiskritisasi data bertipe numerik. Binary Particle Swarm Optimization (BPSO) berfungsi untuk menseleksi subset fitur yang berlebihan dan kurang informatif pada dataset atau yang disebut dengan seleksi fitur. Pengujian dilakukan dengan menggunakan metode 10-fold cross validation pada dataset Chronic Kidney Disease (CKD) yang didapat dari UCI Machine Learning Repository. Hasil pengujian pada penelitian ini didapatkan bahwa penerapan seleksi fitur dengan BPSO mampu meningkat kinerja klasifikasi C4.5 dengan nilai accuracy, precision, recall dan f-measure berturut-turut yaitu 96%, 96,869%, 96,8% dan 96,781% serta waktu komputasi yang didapatkan yaitu  62,56 ms. Sedangkan pada pengujian parameter BPSO, didapatkan nilai parameter terbaik dengan jumlah partikel adalah 15, jumlah iterasi adalah 40, nilai c1 adalah 1 dan c2 adalah 1,2 serta nilai bobot inersia (w) adalah 0,9.

Dynamic behavior of roller bearings under the loads can be described by a mathematical model. The dynamic bearing model is modeled using the finite element method. Analysis of the dynamic behavior of the radial bearing refers to the modal analysis, ie. the determination of the natural frequencies, the main forms of oscillation and damping for the considered bearing, with different values of the clearance. This analysis is based on the simultaneous analysis of excitation and response signals in the time domain or more often in the frequency domain. In addition to FEM, it was also performed the experimental test on a FKL 6006 bearing with different clearance values. Within this paper, a comparison of the results of the modal analysis performed experimentally with the results obtained by the finite element method was performed. The compared results show a satisfactory deviation.

As it is known, emissivity is paramount for accurate temperature measurement using IR thermography. The emissivity of metals is particularly interesting due to its variability in relation to surface conditions (surface roughness and oxidation state), viewing angle, temperature, and wavelength. In the frame of this paper, knowledge regarding metal surface coatings and its effect on emissivity has been gained in an effort to improve risk assessment of workplace burns arising from hot metal surfaces. The present study examined the emissivity of two-component polyurethane metal covering coat on steel and grey cast iron depending on temperature and coating thickness. It was concluded that metal coating leads to moderated metal heating and increases constancy of emissivity compared to uncoated metal surfaces.

Use of straight round bars is necessary in industries due to requirement of raw material as input for production of value-added products. Bars are often available in bent condition; hence straightening is a necessity before commercial use. Therefore, choosing a proper lot of straightened bars with acceptable level of residual curvature is a quality requirement. Use of statistical analysis by Factorial Design will help in decision making through appropriate Test Hypothesis for quality criterion of acceptable range of residual curvatures. This paper has made an attempt to look into the applicability of Factorial Design in bar straightening process.
