Authors: Mishchenko L. , Dunich A. , Dashchenko A. , Kozub N. , Hlushchenko L.
Published: September 2022

Goal. Cherry leaf roll virus (CLRV) infects naturally a wide range of herbaceous and woody plants, different species of trees, shrubs, horticultural, ornamental, weed plants and causes significant economic losses in many hosts and countries. CLRV on elderberry species was reported in Europe, USA, Iran and North America. Recently this virus has been detected in sour and sweet cherry fruit orchards in Ukraine. Testing of other hosts than Prunus was performed in Ukraine only recently. The aim of the study was to test the black elderberry plants (Sambucus nigra L.). for the presence of CLRV in the Poltava region and Kyiv regions.

Methods. Sampling was carried out in the summer–autumn period in 2019—2021 in the territories of the Poltava and Kyiv regions and in Kyiv city. Samples of healthy elderberry plants were also analyzed. Visual diagnostics, enzyme-linked immunosorbent assay in DAS-ELISA modification, total RNA extraction, RT-PCR with primers for a 412 bp fragment of the 3’ untranslated region of the CLRV genome, and statistical data analysis were used in this research. PCR products were separated on an 1.5% agarose gel. Commercial CLRV preparations were used for positive controls in DAS-ELISA.

Results. Thirty three elderberry samples with symptoms of leaf rolling and mosaics of varying degrees were selected in the territory of the Poltava and Kyiv regions and in Kyiv city in 2019 and 2021 and used in the study. ELISA and RT-PCR results showed that 82% of the tested black elderberry samples were infected by CLRV.

Conclusions. The presence of CLRV, its harmfulness for elderberry plants, and Sambucus potential to serve as a reservoir for the virus indicate the necessity of testing a wider range of plant species for сherry leaf roll virus in Ukraine.

Published: September 2022

Goal. To determine the species composition of weed plants and their dominant role, to establish the type and level of weediness of corn crops for grain grown in stationary crop rotation and monoculture in the conditions of the Eastern Forest Steppe of Ukraine.

Methods. The research was carried out by route surveys of crops in field experiments.

results. Аccording to the research data in 2011—2017 in corn sowing for grain found 33 types of weedy pollinators that belonged tо 17 families and contaminants were found in corn for grain crops, of which the most common were Asteraceae (9 species), Poaceae (4 species) and Polygonaceae (4 species). There were found 25% fewer species of weed plants (24 species) in corn for grain crops in monoculture than in crop rotation (32 species). Among weed plants, spring early and late species prevailed (65.6% — in crop rotation; 62.5% — in monoculture). The main types of weeds (occurrence of the species from 78 to 100%) in crop rotation were Setaria glauсa (L.) Beauv., Echinochloa crus-galli (L.) Roem. et Schult., Chenopodium album L., Amaranthus retroflexus L, Solanum nigrum L., Polygonum lapathifolium L., Cirsium arvense (L.) Scop., Convolvulus arvensis L., and in monoculture — C. album, Ambrosia artemisiifolia L., Xanthium strumarium L., C. arvense. According to the sum of the shares of dominance and subdominance among weed plants, C. arvense prevailed in crop rotation (78%), and X. strumarium prevailed in monoculture (100%). The type of weediness in corn for grain crops in crop rotation differed annually from the type of weediness in monoculture. For the most part, cereal annual weed species prevailed in crop rotation, and dicotyledonous weed species prevailed in monoculture. Under conditions of crop rotation, a lower level of weediness was observed almost every year than in monoculture.

Conclusions. The type of weediness in crops of corn for grain in crop rotation differs from the type of weediness in monoculture. for the most part, cereal annual weed species predominate in crop rotation, and dicotyledonous weed species predominate in monoculture.

Authors: Baranets L. , Balan H. , Perepelytsya O. , Leshchenko A.
Published: September 2022

Goal. To clarify the species composition of the order Cicada (Hemiptera: Cicadinea (Auchenorrhyncha)) and their distribution in the grape agrocenoses of the Northern Black Sea Coast of Ukraine. Investigate the peculiarities of the seasonal dynamics of the Japanese grape cicada (Arboridia kakogawana Mats.) and identify the varieties that are most susceptible to damage by this leafhopper.

Methods. Phytosanitary monitoring of leafhopper distribution in grape agrocenoses, the results of which determined the species composition of cicadas, the number of populations and the nature of plant population. The study of seasonal dynamics and determination of the flight peaks of the imago of the Japanese grape leafhopper was carried out with the help of yellow glue traps.

Results. The data of the increase of species composition and expansion of the range of the order Cicadinea in agrocenoses of vineyards in the conditions of the Northern Black Sea zone of Ukraine are presented. The most significant changes were noted in invasive species of leafhoppers. The reasons are the process of adapting the development of cicadas to the conditions of grape ecosystems in the region. The dynamics of the number of Japanese grape leafhopper (Arboridia kakogawana Mats.) is given and the periods of its maximum abundance in industrial vineyards are traced. The number of generations of A. kakogawana was determined and the varieties that are most susceptible to damage by this cicada are indicated.

Conclusions. According to the results of the research, 12 species of leafhoppers from different ecological and trophic groups belonging to 5 families were identified. It was noted that among the studied leafhoppers, the most common is the invasive species of the Japanese grape leafhopper, which ranges from 28.7 to 46.5% of the total number of populated bushes. It is noted that in the conditions of the Northern Black Sea leafhopper develops in three generations. Adults are caught from early June to mid-October. During this time, 3 peaks of leafhopper are recorded — the first — in mid-July, the second — in the first decade of August and the third peak — in early September. The development cycle of one generation is about 35—40 days. Migration to wintering grounds begins in mid-September. It was found that all surveyed grape varieties were inhabited by Japanese grape leafhopper, but it was analyzed that the number of populations in the varieties is different. Varieties with medium or more intense leaf pubescence were more intensively populated, such as Cabernet Sauvignon, Sukholimansky White, Odesa Souvenir, Chardonnay, Odessa Black, Rkatsiteli and Muscat Tairovsky. The smallest number of leafhoppers was found on varieties without pubescence or with weak pubescence of leaves on the underside, it is Arcadia, Flora, Riddle, Raisin Tairovsky, Kardishah and others.
EDUCAÇÃO PROFISSIONAL E TECNOLÓGICA, OS INSTITUTOS FEDERAIS E A INCLUSÃO
Authors: Moreira de Oliveira Wanessa , Carvalho Delou Cristina Maria
Published: September 2022

A constituição da Educação Profissional e Tecnológica e da Educação Especial no Brasil são, historicamente, marcadas por perspectivas excludentes, de acentuação das desigualdades sociais, da diferenciação de classes e do dualismo educacional. Apresentam similaridades e interfaces, na medida em que foram inicialmente propostas como modalidades diferenciadas de ensino voltadas para os menos favorecidos, aos marginalizados, não como forma de desenvolvimento intelectual e formação geral/básica, mas como forma de ocupação e treinamento para exercício laboral. Logo, para melhor compreensão da educação profissional voltada às pessoas com deficiência é preciso analisar as condições em que se desenvolveram a educação profissional e a especial. Assim, o presente trabalho se propõe a refletir sobre a constituição da Educação Profissional e Tecnológica e dos Institutos Federais no Brasil e suas correlações com o processo de inclusão escolar de estudantes público da Educação Especial. Trata-se de um estudo qualitativo e de cunho bibliográfico, por meio do qual foi possível constatar que várias idas e vindas foram registradas na tentativa de superação dessa lógica excludente e dualista da Educação Profissional e Tecnológica e da Educação Especial, destacando-se as propostas do ensino médio integrado ao ensino técnico profissional e da Educação Especial na perspectiva inclusiva. Nesse cenário, os Institutos Federais despontam como possibilidade da superação do dualismo educacional: educação geral/básica versus educação profissional, Educação Especial versus educação inclusiva. Contudo, observa-se que, na atualidade, "novos" (des)caminhos têm sido apresentados para guiar as propostas de educação profissional e inclusiva, colocando em xeque os ideais almejados pelos Institutos Federais.

Caracterización del Desarrollo Económico Rural y el Papel del Turismo
Authors: Andere Reyes Ana Elena , Moreno Moreno Luis Ramón
Published: September 2022

Este trabajo caracteriza el desarrollo económico de la comunidad rural de Bahía de los Ángeles (BDLA), México, mediante la construcción de una matriz de contabilidad social (MCS), bajo la premisa de que el sector turismo constituye el pilar de desarrollo económico, que a su vez se sustenta en el aprovechamiento y atractivo de sus recursos naturales, por encima de la pesca y otros sectores. Los resultados obtenidos permiten documentar que es la actividad pesquera, aún con restricciones medioambientales, de la mano del comercio y los servicios, quienes explican de una mejor manera la dinámica local, mientras que el turismo, presenta un papel marginal. Sin embargo, se concluye que el desarrollo de BDLA requiere un enfoque de política pública mixta que integre factores endógenos y exógenos en el que las características geográficas, así como la riqueza natural y la biodiversidad deben ser valoradas como ventaja competitiva, por tanto, la pesca como el turismo deberán jugar un papel preponderante para el desarrollo futuro de la comunidad. Se proponen algunos elementos de política pública.

Published: September 2022

La presente investigación tiene como objetivo analizar el concepto de gastronomía sustentable e identificar grupos de interés, las estrategias, estándares de calidad, lineamientos asociados y los beneficios obtenidos de su aplicación en restaurantes y eventos de carácter gastronómico en el contexto internacional.

Metodológicamente se realizó una revisión exhaustiva de la literatura existente en fuentes secundarias (libros, revistas académicas y páginas web) para obtener la información más relevante. Ésta se presenta en seis rubros: caracterización de gastronomía sustentable, grupos de interés en la gastronomía, negocios gastronómicos sustentables, eventos en la gastronomía, políticas públicas y, finalmente, estrategias para la generación de gastronomía sustentable y beneficios obtenidos. Se concluye con los rasgos que la definen, los actores que están involucrados en ella y los destinos que resaltan a nivel internacional. En el caso de los países europeos (Italia, Reino Unido, España) existen normas que relacionan la gastronomía con la sustentabilidad, asimismo, organismos de chefs bien establecidos y políticas públicas que tienen en cuenta a organismos privados para elaborar estrategias. Sin embargo, en Latinoamérica (Perú, Chile, Colombia, México) se están comenzando a incorporar aspectos de sustentabilidad al creciente desarrollo de la gastronomía. Mientras que en países de Europa resaltan estándares de calidad y lineamientos asociados a la gastronomía sustentable, en Latinoamérica la normatividad es la gran ausente. En el caso de México recientemente se estableció la Política de Fomento a la Gastronomía (2015), siendo la base para el desarrollo de la gastronomía con puntos estratégicos orientados a la sustentabilidad del sector.

Published: September 2022

Several studies have focused majorly on dietary evaluation, microbial contamination, and nutrient composition of dead hens and rendered spent hens, leaving out the effects of feeding poultry byproducts compost on yolk fatty acid profile, egg sensory analysis, and blood biochemistry in laying hens. This study investigated the effects of including poultry byproducts compost in the diet on yolk fatty acid profile, egg sensory characteristics, and serum biochemical indices of laying hens. A total of 150, 18-week-old laying hens (Novogen White) were randomly stratified to 5 groups with 5 replicate floor pens of 6 birds per pen, under a completely randomized design (CRD). Diets (iso-caloric and iso-nitrogenous) with 0, 2.5, 5, 7.5, and 10% compost levels were fed ad-libitum from week 18 to 42. At 42 week of age, yolk fatty acid composition, egg sensory characteristics, and serum biochemical status of hens were examined. No differences (P>0.05) in yolk fatty acid composition were observed among the diets. Egg sensory values were slightly reduced for eggs laid by hens fed compost at different levels compared to control hens; however, this difference was found to be not significant (P>0.05). Alike, serum biochemical indices were not affected (P>0.05) by different levels of compost in the diet. Taken together, these results suggest that poultry waste compost could be utilized in layer rations up to 10% with no detrimental effects on yolk fatty acid composition, egg sensory quality, and serum biochemical profile. Furthermore, the utilization of compost in layer rations could effectively reduce feed cost.

IJTIHAD AS A SOURCE OF DYNAMICS ESTABLISHMENT OF ISLAMIC CULTURE
Authors: Pulungan Enny Nazrah , Akbar Ali
Published: September 2022

Ijtihad is the third pillar of Islam, after the Qur'an and Sunnah. The literal meaning of ijtihad is, that it comes from the word ijtahada, which means to devote energy, squeeze the mind, try hard, and work as much as possible. The message of Islam is a blessing for all nature, and a blessing for humans, how Islam guides human life which includes spiritual and physical aspects according to its message. In the worldly life of Muslims, it is necessary to formulate and enforce an Islamic cultural system that can create goodness for all human beings. A cultural system that must experience continuous development and progress as the nature of culture itself, which is always in tune with the spirit and demands of the times, but still with the breath of Islam. So, to face the changing life and answer every challenge of the times, Islam puts down a doctrine of free thought called ijtihad. If the Qur'an and Sunnah are the two basic sources of Islamic teachings, then ijtihad functions as a driving force.
ANALYSIS AND PROSPECTS OF TECHNOLOGICAL AND DESIGN FEATURES OF SOWING MACHINES
Authors: Hrushetskiy Sergiy , Omelyanov Oleh , Kyrychenko Roman
Published: September 2022

To date, sowing is one of the most urgent tasks, therefore, universal sowing equipment is widely in demand, which should ensure a uniform distribution of the number of plants per unit area to create the same conditions for development. It is the sowing machines of this type that will largely solve the problems of timely high-quality sowing with a combination of other technological operations - soil preparation, fertilization, embedding, rolling, etc. At the same time, a significant amount of technical and human resources will be released, sowing dates will be strictly observed.
Accordingly, the purpose of the study was to conduct a comparative analysis and prospects for the technological and design features of sowing machines to improve the operational reliability of the mechanism for copying the relief of sowing machines using advanced structural materials.
The research was carried out by the method of technological and structural analysis of technologies and machines for sowing machines. In the process of research, methods of comparison and mathematical modeling of technological processes were used. The information base of the research was the works of Ukrainian and foreign scientists on technologies and machines for sowing.
On the basis of the comparative analysis and the prospect of technological and design features of sowing machines, it was found that friendly stairs (at least 90%), and, as a result, a high yield depend on the quality of the work of the parallelogram mechanism for copying sowing complexes. The reason for the violation of agricultural requirements for sowing, in particular the depth and uniformity of seed placement, is the low durability of the mechanisms for copying the soil surface. It has been established that the main reason for the low reliability of these mechanisms is the use of "steel-to-steel" tribo-couplers in their mobile joints, which ensure operability with frequent (every 40...50 hours of operation) maintenance (lubrication). It has been revealed that it is promising to introduce polymer-composite materials for structural purposes in the movable mates of the parallelogram copying mechanism, which will change the working conditions and increase the durability of this mechanism as a whole.
To solve the problems associated with the development and study of the properties of new or modified PCM in the movable joints of sowing machines, it is necessary to conduct a theoretical justification and experimental feasibility of using polymer parts and their effectiveness. It is necessary to develop a model that describes the dynamics of loads under different operating conditions of the disc coulter. It is also necessary to carry out theoretical calculations that take into account the change in the load on individual nodes of the parallelogram copying mechanism.

Published: September 2022

We aim to elucidate the discrepancies in acute stroke mortality among primary local governments and identify the risk factors of the mortality at loco-regional level to establish tailored health policies in Korea.
From January 1, 2017 to December 31, 2019, the mortality rates of patients who died from stroke within 30 days of hospitalization in 226 municipalities were analyzed using the claims data accumulated by Health Insurance Review and Assessment Service. Demographic factors (elderly population ratio, gender ratio, alcohol consumption rate, smoking rate, subjective health status awareness), socioeconomic factors (ratio of old houses, financial autonomy rate, rate of medical aid beneficiaries) and medical resource factors (number of hospitals/ doctors) were analyzed.
Acute stroke mortality rate in Korea is 12.1 ± 2.2%. The region with the lowest mortality rate is Gyeonggi Province (local government mainly consisting of urban cities) and regions with the highest mortality rates are North Chungcheong Province and South Jeolla. The elderly population is associated with mortality using overall nationwide data. It was also risk factor for stroke mortality in the cities or counties in rural areas. The male-female ratio, alcohol consumption rate, financial autonomy rate, and number of hospitals in the region were also mortality risk factors based on the data of urban cities.
Based on the results from counties, the proportion of elderly population and financial autonomy rate were found to be a significant risk factor for stroke mortality in small towns in rural areas. Regional differences of acute stroke mortality were also found.
Aside from demographic factors (proportion of elderly population), socioeconomic factors (financial autonomy rate) were identified as risk factors for acute stroke mortality. Collectively, it is necessary to build health care policies that address the health inequality at the loco-regional level.

Eine Herausforderung beim Spannen dünnwandiger Werkstücke stellt die Fertigung engtolerierter Werkstücke dar. Aufgrund der geringen Steifigkeit dünnwandiger Werkstücke können durch zu hoch eingestellte Spannkräfte unzulässig hohe Maß- und Formabweichungen auftreten. Zusammen mit der HWR Spanntechnik GmbH erforscht das Institut für Fertigungstechnik und Werkzeugmaschinen (IFW) der Leibniz Universität Hannover daher ein neuartiges sensorisches Spannfutter zur präzisen Spannkrafteinstellung.

 

Clamping thin-walled workpieces is a challenging problem in high precision turning. Due to the low stiffness of thin-walled workpieces, high workpiece deformations can occur when clamping forces are set too high. For this reason, a sensory chuck for precise clamping force adjustment is being researched by HWR Spanntechnik GmbH and the Institute of Production Engineering and Machine Tools (IFW) at Leibniz Universität Hannover.

Dieser Beitrag beschreibt die Entwicklung eines Greiferfingerbaukastens, der für eine automatisierte Konfiguration anwendungsspezifischer Greiferfinger genutzt werden kann.

 

Handling processes are part of almost every automated process. While the handling device is relatively easy to adapt to new handling tasks, the design of the gripper fingers as the interface between handling system and object is usually done manually, based on empirical knowledge. This paper describes the development of a gripper finger construction kit to automate the configuration of application-specific gripper fingers.

Dieser Beitrag stellt ein Konzept für die Integration von interaktiven Simulationsmodellen in einer Virtual-Reality (VR)-Simulationsumgebung vor. Dabei werden die Simulationsmodelle aus der virtuellen Inbetriebnahme (VIBN) von Produktionsanlagen betrachtet. Ein Ziel der erweiterten VIBN mithilfe von einer VR besteht darin, die Lücke zwischen VIBN und der realen Inbetriebnahme zu schließen. Damit das vorhandene VIBN-Modell möglichst einfach in der VR-Visualisierung integriert werden kann, ist es essenziell, eine Durchgängigkeit des Simulationsmodells im Engineering zu gewährleisten. Aus diesem Grund wird auf das bestehende Austauschdatenformat „AutomationML“ eingegangen.

 

This paper presents a method for integrating interactive simulation models into a virtual reality (VR) simulation environment. To this end, simulation models from virtual commissioning (VIBN) of production plants are considered. One goal of enhanced VIBN using VR is to close the gap between VIBN and real commissioning. To integrate the existing VIBN model as easily as possible into the VR visualization, it is essential to ensure engineering continuity for the simulation model. For this reason, the existing exchange data format AutomationML will be discussed.

AR-Assistenz für die modulare Spannmittelmontage/Error-free Assembly of Clamping Systems – Assembly Assistance for Modular Clamping Systems
Authors: Sauer Steffen , Berndt Dirk
Published: September 2022

In der CNC-Bearbeitung ist es zur Kollisionsvermeidung sehr wichtig, dass real aufgebaute Spannsysteme exakt der Vorgabe aus der CAD/CAM-Simulation entsprechen. In diesem Beitrag wird ein industrietaugliches Assistenzsystem präsentiert, mit dem per Augmented Reality (AR) die manuelle Montage von modularen Spannsystemen unterstützt wird und so Fehler vermieden werden können. Es wird aufgezeigt, dass die Kamera-Monitor-basierte AR geeignet ist, um unter rauen Bedingungen intuitive Montageanleitungen zu visualisieren. Dadurch lassen sich Bearbeitungszeiten in der CNC-Maschine verkürzen und die Montage beschleunigen.

 

In CNC machining, the similarity of real assembled clamping systems compared to the constructed clampings in CAD/CAM is of critical importance. If differences are present, unintentional collisions between tool and clamping system can occur, which may lead to total breakdown. In this work we present an Augmented Reality (AR) industry-ready assistance solution, which helps workers to reduce the error rate when clamping systems are assembled manually. We will show that camera-screen-based AR is well suited to present assembly instructions in harsh environmental conditions and that by using this solution machining times can be reduced and the assembly itself can be accelerated significantly.

Published: September 2022

Um die Nachfrage nach herstellerunabhängigen Erkenntnissen über die Wirkung und Effekte von industriell eingesetzten Exoskeletten zur Prävention von körperlicher Überlastung und physischen Schäden zu bedienen, wurde in einer Studie das subjektive Belastungsempfinden von 72 Probanden während drei unterschiedlichen standardisierten Tätigkeiten untersucht. Die Ergebnisse zeigen eine signifikante Reduktion der wahrgenommenen Belastung bei der Verwendung eines Exoskeletts im Vergleich zur Durchführung ohne Exoskelett, welche konstant über alle definierten Tätigkeiten auftritt.

 

To meet the demand for manufacturer-independent insights on the effects of industrial exoskeletons, this study analyzes how 72 subjects rated the perceived exertion during three different standardized work tasks. Results show a significantly reduced perceived exertion when using an exoskeleton compared to not wearing an exoskeleton. This effect was constant over all defined work tasks.
