Authors: Permana Diki I. , Rusirawan Dani , Farkas Istvan 
Published: July 2022

Renewable energy sources have grown in popularity in a variety of applications over the last century, particularly in solar power generation. Exploiting solar energy in low-medium temperature systems via the organic Rankine cycle (ORC) is a prospective idea for producing clean energy in remote areas at a low cost. The amount of solar energy available in Hungary is sufficient to power the ORC system. In this study, a parabolic through collector (PTC) solar collector is used to convert solar thermal energy into a heat stream that is used to boil the working fluid of R134a, which was chosen as a good ORC working fluid because it has a low boiling point as well as a low ODP and GWP value. Many recent studies have studied solar-ORC both from a theoretical and experimental point of view in various areas, especially in design system. In this study, the preliminary design that overcomes the need for solar-ORC, including an analysis of energy, the efficiency of the system, and turboexpander characteristics using different pinch temperatures (10 °C and 5 °C) will be elaborated. The weather data in June is used for initial data input, for calculations in the PTC solar collector. The result shows that the ORC system with 5 °C has a better result in view of the energy from the turbine and the thermal efficiency, compared to the ORC system with 10 °C.

Listeriosis is an important emerging bacterial food-borne zoonotic disease caused by Listeria monocytogenes. During the last two decades, the organism has been implicated in several food-borne disease outbreaks making it a serious public health hazard. The pathogenic strains of Listeria can cause severe illness in man after the ingestion of contaminated food products, especially the refrigerated foods of animal origin. In India, very few studies have been carried out in respect to the occurrence and incidence of L. monocytogenes. Assam, one of the eight states of Northeastern India, where approximately 79.0 percent of the total population are non-vegetarians. Chicken meat, pork, chevon and beef are exclusively taken as regular food items throughout the state. The present study describes about isolation, identification and molecular characterization of L.monocytogens from different foods of animal origin from Assam, India. A total of 750 different meat (chicken, chevon, pork and beef) and milk and their products (curd and paneer) samples were collected and analyzed for presence of Listeria. Isolation of L. monocytogenes was done from different food samples of animal origin by using selective enrichment method. PCR was employed for confirmation of the suspected cultures of Listeria targeting prsand16SrRNAgene. Upon confirmation, the isolates were further characterized based on 16S rRNA gene and phylogenetic analysis was performed. Of 750 samples, 48 (6.4%) samples were found positive. The highest rate of isolation of Listeria spp. was recorded in raw milk (8.95%) followed by curd (6.58%), chevon (5.36%), chicken (5.74%), pork (5.98%) and beef (3.75%). Molecular characterization of the isolates based on 16S rRNA gene of L.monocytogens isolated from foods of animal origin from Assam with that of other sequences reported from different parts of the world revealed that all the isolates of the present study are clustered along with other L.monocytogens isolates reported from different parts of the world, however, showing more closely related to isolates reported from China.

THE ACQUISITION OF COMMUNICATIVE COMPETENCE AS ONE IMPORTANT ASPECT OF CULTURE: HOW SHOULD COMMUNICATIVE COMPETENCE BE BUILT?
Authors: Saragih Willem 
Published: July 2022

As the arts and the manifestations of human intellectual achievement regarded collectively, culture, which is realized in the way members of a community communicate through language and behavior, as the reflection of their minds, is an integral aspect of life to look into. One element of this is communicative competence. In order for people to succeed in their sharing anything being communicated, besides being able to produce the language in spoken or in written form accurately, they must also know which word and sentence pattern to use as well as its appropriate prosodic features. This implies that in actual communication both linguistic competence and communicative competence are equally needed and they for a successful acquisition both aspects of communication should be taught simultaneously, with theory and examples. As the acquisition of communicative competence is a long process – similar to learning language, both of these crucial competences should be taught as the child start learning the language. This method of communicative competence is usually applied in Japan – a nation that puts loosing face as a loss of existence. Therefore, as a reflective value which can be gained by Indonesia from the practice of such things in that advanced country is that children in Indonesia should also be exposed to explanations and examples of communicative competence along with linguistic competence. Key Words: communicative competence, acquisition, politeness, role and status

Published: July 2022

Los dispositivos como, teléfonos móviles y tablets son aliados de la educación, dado que permiten acceder a contenidos y actividades educativas desde cualquier lado y en cualquier momento. Sin embargo, el apoyo o asistencia al estudiante no siempre se encuentra disponible cuando un estudiante presenta un problema en su aprendizaje. En este sentido, es conveniente contar con algún mecanismo automatizado que permita detectar esos problemas para así poder ofrecer la ayuda en el momento adecuado y de la mejor manera. En esta situación, la tecnología de agentes inteligentes puede resultar beneficiosa, debido a que es capaz de evaluar las acciones de cada estudiante y detectar problemas, brindando la ayuda correspondiente. En este trabajo se presenta el desarrollo de un prototipo de sistema de recomendación de tutores, basado en una arquitectura multi-agentes para monitorear la interacción del estudiante con un entorno educativo virtual ubicuo en el nivel universitario, y detectar el tema en el que el estudiante presenta problemas. La recomendación de tutores se realiza a través de un mapa teniendo en cuenta sus ubicaciones, y de esa manera el estudiante tiene la libertad de acudir al más cercano. De las pruebas realizadas se demostró que el sistema propuesto facilita al estudiante la tarea de encontrar un tutor adecuado que se encuentre geográficamente cerca y lo pueda ayudar en el tema que presenta problemas.
Importancia de la proporción cobre/zinc: una aproximación al análisis de los efectos de la suplementación in vitro sobre el genoma

Published: July 2022

El cobre (Cu) y el zinc (Zn) son micronutrientes esenciales que participan en numerosas actividades metabólicas. La proporción Cu/Zn resulta más importante aún que la concentración individual de cada uno de éstos y es uno de los parámetros asociados con la reducción de la homeostasis frente a un evento desestabilizador. Debido a que las deficiencias y los excesos de micronutrientes no se detectan por técnicas antropométricas, es necesario el diseño de modelos experimentales que permitan investigar sus efectos y aporten información para implementar políticas de prevención sanitarias. Por dichos motivos, el objetivo del presente trabajo fue analizar el efecto de la suplementación combinada con Cu y Zn sobre el genoma teniendo en cuenta la proporción entre ambos micronutrientes, en un modelo experimental con sangre periférica cultivada in vitro. Se llevó a cabo el ensayo cometa y se determinó el índice de daño (ID). Las células fueron cultivadas durante 5 días y se realizaron 8 tratamientos: 3 combinaciones con sulfato de zinc (SO4Zn) y de cobre (SO4Cu) y sus respectivos controles. Para el análisis estadístico se utilizaron los ensayos de ANOVA y el método LSD de Fisher. Se observaron frecuencias de ID significativamente aumentadas a medida que la proporción Cu/Zn se incrementó. Dado que el Zn y el Cu juegan un rol fundamental tanto en el mantenimiento de la estabilidad genómica como en el crecimiento de los niños, el desarrollo de enfermedades y el proceso de envejecimiento, es fundamental determinar los valores adecuados de ingesta diaria combinada de ambos micronutrientes.
SISTEM PEMILU SEBAGAI WUJUD DEMOKRASI DI INDONESIA: ANTARA ORDE LAMA, ORDE BARU DAN REFORMASI

Published: July 2022

Indonesia is a country that upholds the values ​​of sovereignty in the nation and state. However, the transitional period with several elections that have been held has not been able to make Indonesia a well-established and well-democratic country. This shows that the legal system in Indonesia is still weak, which changes every time an election is held. This paper explains the journey of the democratic system and elections that have been carried out in Indonesia from time to time by conducting historical and juridical studies and the findings in this paper conclude that the ethics and morality of the personality of the political elite need to be built so that the democratic system in Indonesia can run well, because of the debate. politics and democracy so far have not been able to make political elites realize that democracy is a process that runs from the individual level. If the principles of democracy are mature from the individual level, they may be easily applied in the public political community, so that it will have an impact on changing the democratic system in Indonesia for the better.
Abstrak
Indonesia merupakan negara yang menjunjung tinggi nilai-nilai kedaulatan dalam berbangsa dan bernegara. Akan tetapi, masa transisi dengan beberapa Pemilu yang telah dilaksanakan ternyata belum mampu mengantarkan Indonesia sebagai negara yang berdemokrasi dengan baik dan mapan. Hal ini terlihat masih lemahnya sistem hukum di Indonesia yang berubah-ubah setiap akan menyelenggarakan Pemilu. Tulisan ini menjelaskan perjalanan sistem demokrasi dan Pemilu yang pernah dilaksanakan di Indonesia dari masa ke masa dengan melakukan kajian historis dan yuridis serta temuan dalam tulisan ini menyimpulkan bahwa etika dan moralitas kepribadian elit politik perlu dibangun agar sistem demokrasi di Indonesia dapat berjalan dengan baik, karena perdebatan politik dan demokrasi selama ini tidak mampu menyadarkan para elit politik bahwa demokrasi adalah sebuah proses yang berjalan sejak tingkat individual. Apabila prinsip demokrasi sudah matang dari tingkat individunya, mungkin akan mudah diaplikasikan di dalam komunitas politik yang bersifat publik, sehingga akan berdampak pada perubahan sistem demokrasi di Indonesia yang lebih baik.
Tree Species Biodiversity in Small Ukrainian Towns
Authors: Zibtseva Olha 
Published: July 2022

Abstract
Biodiversity is one of the important indicators of ecosystem sustainability, which is less studied in relation to urban areas, particularly Ukraine, and even more so in small towns. Taking the example of three small Ukrainian towns, the biodiversity of tree species is compared in the article. The studied small towns are located in two geographic zones, mixed forests (Polissya) and forest-steppe, and administratively, in Chernihiv and Kyiv regions. An inventory of trees in the residential area of Ukrainka, in the central streets of Novhorod-Siverskyi, as well as in the central part and all streets of Vyshhorod was conducted. Thus, the species richness of trees both between the studied towns and between its central part and the whole territory of the town was compared. The species structure of tree plantings in terms of richness, diversity, dominance, alignment, and similarity was assessed. The obtained results were subjected to cluster and correlation analysis. It was found that the greatest diversity is characteristic for the dendroflora of the whole territory of Vyshhorod, which is the fastest growing town, located closest to the capital. The dendrofloras of small towns were quite similar to each other. The values of similarity indices varied in a wide range: Jacquard’s index from 0.26 to 0.56 and Sørensen index from 0.41 to 0.66. The lowest degree of similarity was found with the dendroflora of the most distant Novgorod-Siverskyi town. Mainly the urban plantings require enrichment of the tree species composition, taking into account their resistance to anthropogenic impacts and climate change.

Published: July 2022

Abstract
The profound impact of the COVID-19 pandemic and the Ukraine crisis 2022 on tourism has rendered forecasts of tourism demand obsolete. Accordingly, scholars have begun to look for the best methods to predict the recovery of tourism. In this study, econometric and judgmental methods were combined in order to to forecast the possible ways to tourism recovery in Slovenia. The goals of this paper are to show and assess the current offerings and potential for the development of tourism in Slovenia, and to point out the advantages and challenges in the development of tourism in this type of destination. Statistical methods were used for benchmark analysis, while Box and Jenkins approach and ARIMA modeling were used for forecasting Slovenian tourism until 2030. The datasets are analyzed using Tableau 2022.1. Our findings show that Slovenian tourism will be slower on the uptake and is not likely to fully recover until 2026, due to COVID-19 related uncertainty. A steep jump in daily COVID-19 infections in China and the Ukraine crisis which is affecting political and economic stability in the world is also slowing down the speed of recovery. In 2019, Chinese, Russian and Ukrainian tourists generated 5% of all tourist arrivals and overnight stays. In particular Russian tourists were well-known for their high consumer expenditure and thus desirable to the destination places. To mitigate the drop in tourist arrivals, Slovenia should do two things, namely concentrate on traditional markets, i.e. Austria, Italy, and Germany, which altogether represent 1/3 of all tourist arrivals and overnight stays, and secondly, it should target new markets, bringing new, innovative products, services, and experiences.
The Impact of the Covid 19 Crisis on the Fiscal Stability of Republic of Srpska
Authors: Gojković Biljana 
Published: July 2022

Abstract
The consequences of the COVID-19 crisis have had a negative impact on the fiscal stability of Republic of Srpska. Although the crisis is not officially over yet, a large number of countries needed to implement fiscal consolidation. Republic of Srpska is one of the small and open economies that are exposed to various negative market distortions. COVID-19 crisis of the most important foreign trade partners of the Republic Srpska has had a negative impact on the economy of Republic Srpska.
The basic idea of the paper is based on the need to analyze the impact of the COVID-19 crisis on the fiscal stability and public finances of Republic of Srpska. The subject of the research is the analysis of the implementation of the fiscal consolidation procedure in Republic of Srpska and the impact on its economic growth. For the implementation of fiscal consolidation, the choice of methods and instruments on which the process of implementing fiscal consolidation is based is very important.
Fiscal consolidation is necessary due to the consequences caused by the COVID-19 crisis and the enormous growth of the deficit. The analysis proves that the measures applied to rehabilitate the crisis have resulted in improved fiscal stability, which ultimately had a positive impact on economic growth. Fiscal consolidation will be successful and expansive if it is carried out by a combined method of increasing revenues and reducing expenditures and if the increase in revenues is caused by the growth of economic activity and not by the tax burden.

Abstract
The aim of this paper is the detection crisis phenomena in the world grain market in the 2022/23 marketing year (MY), which worsened during the Russia-Ukraine invasion on February 24, 2022. Some countries and international organizations have recently expressed concern that the reduction of grain supply on the world market and the rapid rise in its price. Whether the impact of the destabilizing situation on the world grain market on the exacerbation of hunger is an open question. In order to fill the research gap, the paper tries analysis the global market into grain types between 2008/09 MY to 2021/22 MY and identify on it the shares of Ukraine and Russia. Two methods are used to conduct a comprehensive study of the grain market - fundamental and technical analysis. The analysis of the state and dynamics of the main indicators of the world grain market was carried out with the help of fundamental analysis. The results show that the volume of grain production in the world and the two warring countries are growing. Both countries supply about a quarter of all products in the overall structure of world grain exports. Finally, the result also shows that Ukraine and Russia are key exporters of barley, rye, wheat, and corn to low-income and least developed countries. Grain price forecasting through technical analysis was carried out. Based on the results obtained during the fundamental and technical analysis, three scenarios for the development of the grain market and its impact on the problem of hunger were proposed and given recommendations for levelling of crisis phenomena.

Abstract
In Italy, most female immigrant workers, mainly Romanians, are employed in care sectors. This is the reason why many scholars have dealt with the impact of domestic work in Romanians’ lives: looking after our family results, according to them, in depression, anxiety, panic. Our job, on the contrary, aims at demonstrating that working in this sector improves post-soviet women’s social status, rescuing them from a subordinate condition in their native country.
Validation of non-empirical fat-free mass estimation model for a wrist-worn device

Abstract
Fat-free mass (FFM) estimation has dramatic importance for body composition evaluation, often providing a basis for treatment of obesity and muscular dystrophy. However, current methods of FFM estimation have several drawbacks, usually related to either cost-effectiveness and equipment size (dual-energy X-ray absorptiometry (DEXA) scan) or model limitations. In this study, we present and validate a new FFM estimation model based on hand-to-hand bioimpedance analysis (BIA) and arm volume. Forty-two participants underwent a full-body DEXA scan, a series of anthropometric measurements, and upper-body BIA measurements with the custom-designed wearable wrist-worn impedance meter. A new two truncated cones (TTC) model was trained on DEXA data and achieved the best performance metrics of 0.886 ± 0.051 r2, 0.052 ± 0.009 % mean average error, and 6.884 ± 1.283 kg maximal residual error in FFM estimation. The model further demonstrated its effectiveness in Bland-Altman comparisons with the skinfold thickness-based FFM estimation method, achieving the least mean bias (0.007 kg). The novel TTC model can provide an alternative to full-body BIA measurements, demonstrating an accurate FFM estimation independently of population variables.
