Authors: Mkrttchian Vardan
Published: November 2020

In this chapter, the author describes the main new challenges and opportunities of blockchain technology for digital economy in Russia. The study in Russia showed that the Russian research community has not addressed a majority of these challenges, and he notes that blockchain developer communities actively discuss some of these challenges and suggest myriad potential solutions. Some of them can be addressed by using private or consortium blockchain instead of a fully open network. In general, the technological challenges are limited at this point, in terms of both developer support (lack of adequate tooling) and end-user support (hard to use and understand). The recent advances on developer support include efforts by of the towards model-driven development of blockchain applications sliding mode in intellectual control and communication and help the technological challenges and created tools. The chapter shows how avatars may communicate with each other by utilizing a variety of communications methods for sustainable farming and smart agriculture.

Authors: Priya Puja , Kaur Gurjit
Published: November 2020

Agriculture is the primitive and crucial occupation for the people. Urbanization, which indirectly affected the lives of people in the agricultural sector by increasing level of environmental pollution, climate change, degradation of soil and water quality, increasing population, decreasing income from the farming industry, etc. come as a new challenge and makes mass migration of rural people to the cities. To overcome this problem, new technologies are emerging that play a pivotal role in developing smart agriculture based on IoT technology by using smart sensors. Smart agriculture helps improve crop yield, livestock tracking, soil moisture monitoring, remote water tank level monitoring, temperature, and humidity sensing, the security of farmland, monitoring the environmental conditions, and equipment tracking. This helps farmers protect and monitor their property remotely, etc. Internet of things (IoT)-based smart sensors is the new technique for the smart agriculture system. IoT-based smart agriculture system consists of various sensor nodes placed in different locations, internet service, smart remote devices, or computer systems with the internet that monitor the operation of sensor nodes, WiFi, a camera with a microcontroller, and different interfacing sensing nodes for service. Some of the examples of such sensors are temperature sensors for temperature sensing, soil moisture sensors to check the moisture content in the soil, PIR sensors used in the detection of animals, people and other objects present in the farm field, GPS-based remote control robots that perform spraying, weeding, security, moisture sensing, etc. This chapter will have the following sequence introduction of the agriculture sector with the problems it is facing now and a new technique to overcome the current issues, need of IoT in the agriculture sector, the link of IoT technique with wireless sensor network in full detail study of IoT-based system, IoT-based applications, benefits of IoT technique in the agriculture sector, and future scope.
Disease Monitoring of Cucumber in Polyhouse Through IoT-Based Mobile Application
Authors: R. Hemalatha , S. Radha , K. Muthumeenakshi
Published: November 2020

Most countries have an economy that is dependent on agriculture—either in a magnificent or small way, from employment generation to national income contribution—implying that agriculture is inevitable. Polyhouse farming is a new and widely accepted method of farming in the present days. The polyhouse is made in such a way that it can provide water and fertilizers in required amounts in a controlled manner, which can result in high yields. Polyhouse requires severe monitoring of crops as stagnant air, and lack of air circulation will lead to breeding of insects and materialistic loss. Hence, this chapter proposes an IoT-based disease-monitoring prototype for an agricultural/polyhouse application. The prototype is designed and tested to identify the disease onset in cucumbers. This work initially focuses on recognizing the critical cucumber diseases in polyhouse using NodeMCU and Raspberry-Pi-based hardware model. The decisions to be made and the major changes in the sensed parameters if any will be intimated to the farmers using a specifically designed mobile application.
The Disabling Influence of Work-Life Imbalance and the Fourth Industrial Revolution (4IR) on Postgraduate Research Engagement and Progress
Authors: Atibuni Dennis Zami
Published: November 2020

The onslaught of the fourth industrial revolution (4IR) requires employees to have a more complex combination of skills—the 21st century skills—than in the past. The corporate world expects employees to amass these skills from the education system, especially through acquisition of postgraduate qualifications. However, acquiring these skills presents challenges to the students as institutions rarely offer these skills at that level. Low competence in these skills, coupled with work-life imbalance, hampers research engagement and hence progress and completion among postgraduate students. In essence, a lack of the 4IR skills is a disabling reality for postgraduate research students. This chapter presents a desk-based conceptual review of the disabling effects of work-life imbalance and inadequate 4IR skills on postgraduate students' research engagement and general academic progress. Implications for policy and practice include routine provision of hands-on experiences on the 21st century research skills and work-life balance in order to step up their research progress.
Ecological Chemistry Aspects of Food Safety
Authors: Sturza Rodica
Published: November 2020

The presented results reflect the researches carried out over the last decade, having as their object the soil, water, vegetal raw materials, and wines from the Republic of Moldova. The analysis of the possible anthropogenic contamination (NAA method) demonstrated the absence of systematic soil pollution. A total of 30 elements were determined in soil samples and the soil-leaves-fruit transfer factors were calculated. Approximately 3000 samples of local wines have been analysed to determine the residual quantities of pesticides. POPs were not found in any of the wine samples. In most of the examined cases (> 60% of samples), the lack of organic pesticide residues was observed. The migration of phthalates into different solutions from polymeric materials (PVC, rubber) and the influence of the temperature on the extraction rate were investigated. It has been shown that the contamination with phthalate residues occurs predominantly at the stage of grape processing, technological treatment, and storage.

Authors: Col Basak Gokce , Tuggum Sergen , Yıkmış Seydi
Published: November 2020

The most commonly used meat preservation methods include cooling, freezing, drying, vacuum packing, and curing. Meat quality is impaired by a wide range of changes including physical, chemical, microbiological, and enzymatic reactions. Food manufacturers focus on processes that require fewer chemical additives to meet the increased demand of consumers and to obtain more natural, healthy, and nutritious meat products. Non-thermal food preservation methods are one of the new trends to minimise thermal effects on texture, nutritional value, and flavor losses of meats. The chapter focuses on two novel approaches; non-thermal (Pulsed Electric Field) and Atmospheric Pressure Cold Plasma (APCP) Technologies.

Consumer Purchase Preference for the Perception of Quality of Perishable Products in a Smart City
Authors: Rebollar-Xochicale Iván Alonso , Maldonado-Azpeitia Fernando
Published: November 2020

Freshness, flavor, presentation, and nutritional value of fruits and vegetables deteriorate as time passes. That is why the correct implementation of supply chains is a subject of great interest for companies dedicated to the rotation of food marketing. Consumers play a particularly important role: the interaction between the retailer and the consumer determines the waste of food along the supply chain. The consumer's choice behavior and the perception of what is acceptable (or not) affect the management of the offer in the different points of sale dedicated to this line of business, as well as the aesthetic standards to be applied when distributing the products. This chapter explores consumer purchase preference for the perception of perishable products in a smart city.
Value-Added Products From Food Waste
Authors: Gunjal Baban Baburao
Published: November 2020

Food waste is the most challenging issue humankind is facing worldwide. Food waste, which consists of carbohydrates, proteins, lipids, and inorganic compounds, is a biodegradable waste discharged from food processing industries, households, and hospitality sectors. The management of food waste is very important. The food waste generated is usually incinerated or dumped in open areas which may cause severe health and environmental issues. The management of food waste can be done by conversion to different value-added products, for example, phytochemicals, bioactive compounds, food supplements, livestock feed, dietary fibers, biopigments and colorants, emulsifiers, edible and essential oils, biopreservatives, biofertilizers, biofuels, and single cell proteins. The value-added products from food waste will be very eco-friendly. The chapter will focus on different value-added products from food waste.

Food insecurity is a recurrent condition in which members of a household do not have enough food to cover their nutritional needs; this condition contributes to increasing social vulnerability of those affected. In Peru, there are more than 9 million people who suffer this condition, which generates malnutrition and anemia, mostly in children. On the other hand, the waste of food is associated with production the large amounts of greenhouse gas emissions that affect global warming. According to reports in Peru, 20% of what is food produced becomes waste. This scenario in terms of food for Peruvians represents 3 billion calories in wasted food that could feed 2 million people. The Peruvian Food Bank manages food donations, ensuring this food can reach people in need through humanitarian aid entities. This applied research work uses the tools of operations research to determine a solution to the problem of maximizing the combination of food orders to be distributed based on their total nutritional value to the beneficiaries, seeking maximum coverage and minimum logistic costs.
Towards the Development of Salt-Tolerant Potato
Authors: Omondi John Okoth
Published: November 2020

Soil salinity is a major constrain to crop production and climate change accelerates it. It reduces plant water potential, causes ion imbalance, reduce plant growth and productivity, and eventually leads to death of the plant. This is the case in potato. However, potato has coping strategies such as accumulation of proline, an osmoregulator and osmoprotector. In addition, leaching of salts below the root zone is preferred, exogenous application of ascorbic acid and growth hormones are practiced to combat salinity. Breeding and genetic engineering also play key roles in salinity management of potato. Varieties such as: Amisk, BelRus, Bintje, Onaway, Sierra, and Tobique were tolerant in North America, variety Cara in Egypt, Sumi in Korea and varieties Vivaldi and Almera in Mediterranean region. Transgenic lines of Kennebec variety, lines S2 and M48 also proved tolerance due to transcription factor MYB4 encoded by rice Osmyb4 gene.
Sustainable Food Consumption in the Neoliberal Order
Authors: Alapiki Henry E. , Amadi Luke A.
Published: November 2020

In recent decades, we have seen the rise of the sustainable food consumption field and its push for disciplinary space in development studies. This chapter turns to the original impetus of sustainable food consumption and the question of how neoliberal order can be reconciled with the need to save the ecology. Beyond the fundamental objectives, there is a need to assess the links between the global food system, as influenced by neoliberal order, and the signs that it leads to adversity for low-income countries. A review of relevant literature in the sustainable consumption field is explored using content analysis to examine links between neoliberal food consumption dynamics, the logic of global food politics, and the emerging terminological shifts from food consumption to food system. The world systems theory and the Marxian political ecology framework are used to show that sustainability is notable for emphasizing resource efficiency and equitability, which can be useful when sustainability challenges are matched with ecological policies. This chapter makes some policy recommendations.
Nutritional Benefits of Selected Plant-Based Proteins as Meat Alternatives
Authors: Yıkmış Seydi , Atan Ramazan Mert , Kağan Nursena , Gülüm Levent , Aksu Harun , Alpaslan Mehmet
Published: November 2020

Humans meet their nutritional requirements by consuming food, and our body uses naturally sufficient amounts of all necessary nutrients to maintain its functioning. Proteins form the basis of the human diet because they are necessary for immune responses, cell signals, muscle masses, and the repair of damaged cells. Animal and plant food products are the main protein sources in the human diet. Based on scientific evidence, proteins derived from animals recently started to be replaced by plant-based options as prefered proteins for a range of reasons. Consumption of non-meat protein sources being shown to be healthy and environmentally friendly is a major consideration. Plant-based protein is helping minimize high cholesterol, type 2 diabetes, high blood pressure, obesity, certain types of cancer, including colorectal, ovarian, and breast cancers, and a diet based on non-animal proteins could increase life expectancy and decrease greenhouse gases emissions from livestock as less resources are used for plant production. The chapter describes the nutritional benefits and current uses of nine non-animal protein sources and the health benefits arising from replacing animal protein.

Authors: Dube Praxedis , Heijman Wim J. M. , Ihle Rico , Ochieng Justus
Published: November 2020

Feeding the quickly growing population in Africa remains a global challenge. As the demand for food increases, climate change, on the other hand, poses more challenges to agricultural productivity, implying that the provision of sufficient quantities and qualities of food is threatened. Traditional leafy vegetables (TLVs) in Africa are resilient to adverse weather conditions and are naturally rich in nutrients including vitamins A & C, iron, protein and other micronutrients. The objective of this chapter is to assess the potential of TLVs improving food security in Africa. TLVs represent a robust local source of food, their consumption is crucial in complementing Africa's diet with micronutrients. TLVs have therefore the potential to play a major role in improving food security and facilitating food sovereignty. Research on seeds, developing seed systems, coupled by preparing and processing methods to TLV products like cakes or flour is needed to increase their consumption, particularly among the young, elite and urban dwellers.
Veganism in the Bhagwad Gita
Authors: Ranjan Pratyush , Pujari Sanskruti
Published: November 2020

This chapter will start by giving a brief description about the most contextually relevant portions of the Bhagwad Gita (the Song of the Spirit) and go on to establish its stark opposition to egoism in general and anthropocentrism, in particular, which is responsible for most of the global problems in the age of the Anthropocene. It contends that anthropocentrism (including speciesism) is guilty for the globalized industry of animal agriculture that is responsible for large-scale suffering and various major global problems. It then seeks directions from the Gita on the appropriate principled responses to the industry, including that of changing dietary habits towards plant-based sources, before finally exploring whether the Gita would promote veganism.
Interculturally-Critical Digital Storytelling
Authors: R'boul Hamza
Published: November 2020

Narrating personal experiences, stories, or real-life events can engage students in meaningful learning that is interesting and fun. Digital storytelling can support not only knowledge transfer but also realizing socially-just education by promoting inclusive attitudes. This chapter argues for the use of digitally supported storytelling for social justice education. Interculturally-critical digital storytelling is presented as a critical orientation that is sensitive to intercultural issues of power and sociopolitical realities. It makes a case for implementing digital storytelling as a way of introducing experiences and narratives that explore elements pertinent to social justice. Interculturally-critical digital storytelling involves (a) incorporating multicultural literature in order to amplify students' voices and include different cultures, (b) considering storytelling as a creative practice that entails an innovative method of teaching and learning, and (c) emphasizing the need to discuss and question hegemonic normative expectations that perpetuate injustices and inequalities.
What Counts as Literacy for the 21st Century Youth
Authors: Araujo Juan J. , Araujo Dawn L.
Published: November 2020

The writing practices of adolescent learners are far different from those of their parents and teachers. In 2020, adolescents engage in writing bursts through text messages and chats as they play games or share stories throughout the day with friends and family. It has been challenging for high school teachers to take advantage of these literacy activities in a meaningful way to improve writing skills. In this chapter, the authors focus on two adolescents who are in different grades and hold different views of what counts as writing practice. Still, it is clear that both believe in the importance of engaging in the work of writing to learn. The findings of our case studies suggest that one adolescent, a twelfth grader, sees writing practice as integral to his life. The other, a ninth grader, reports that he only engages in writing at school through formulaic assignments that are often boring and unchallenging. The authors found in their study that storytelling and digital technologies are tools for developing flow, critical thinking, and problem-solving skills, engagement, and motivation.

This study is expected to contribute and enrich the theoretical framework of the scientific field of information science, more specifically concerning the interrelations of knowledge management with organizational memory, collectively constructed and linked to issues of efficiency and effectiveness, as well as evidence the relevance of the repertoire memory composed of previous knowledge and know-how for the constitution of memory organization.
Scientific Knowledge, Innovation, and Economic and Social Development
Authors: Silva Elaine da
Published: November 2020

Discussions about innovation in the organizational context were brought up between the mid 18th and 19th centuries; since then, concepts, definitions, and classifications of innovations have been created and incorporated into the academic and organizational contexts. The understanding of such concepts is fundamental for the agents involved to realize the different possibilities for the generation and management of innovation. This chapter, based on a literature review, develops a synthesis of concepts and classifications about innovation and presents a proposal for the analysis of innovative activity based on five dimensions: degree of novelty, object, focus, scope, and development. In addition, based on the assumption that universities are characterized as the most important producer of scientific knowledge in the context of innovation systems, it analyzes the modes of knowledge production and the respective role of scientific knowledge for the generation of innovation.

Published: November 2020

The objective of this research is to contribute to the understanding of the online community by empirically examining the major factors motivating online community members to participate and actively contribute to their communities. In pursuing this endeavor, a comprehensive conceptual model of motivations that drive online community participation is developed based on an extensive revision of the existing relevant literature. However, modest research had been conducted to understand the online participant's motivation to participate in online communities. Thus, the current research model will enhance understanding and add to the relevant existing knowledge by categorizing digital user's motivation to participate in online communities, through the employment of Maslow's hierarchy of needs theory and Herzberg's two-factor theory. The paper used a deductive methodological approach adopted.

Published: November 2020

Teachers and school district administrators, particularly in the United States, are increasingly turning to teacher virtual professional development (VPD) to stay current and learn new pedagogical knowledge and skills. With more English learners (ELs) entering public school classrooms, it is essential to find effective ways to prepare educators to meet the needs of these students. The authors examined the improvement of Texas in-service teachers' English as a second language (ESL) pedagogical and content knowledge after participating in a VPD program designed for developing teachers' ESL instructional capacity. Chi-square analyses were conducted with participant pre- and post-survey data (n=61). Results indicated a significant improvement in teacher knowledge after program completion. There was no difference in teachers' knowledge gains based on their school district location. These findings are in line with other researchers who have found improvement in terms of teacher knowledge and instructional practices after participation in VPD.

Published: November 2020

Although business and researchers acknowledge the importance of social media, little research has been conducted to explore what attracts people to follow brand Twitter accounts. This research attempts to achieve an analytical understanding of the factors that contribute to brand Twitter follower count based on social network and communication theories. Using data from 346 Twitter accounts spanning 48 industries and 31 countries, the authors found that the quality and quantity of tweets, as well as social learning of brand Twitter accounts are positively related to brand Twitter account followers; contrary to popular belief, the use of hashtags and links and interactivity with users are not positively related to brand Twitter account followers. The study is among the first to investigate what attracts brand Twitter account followers, which offers important strategic recommendations for brand social media managers on how to manage their social media accounts.

Published: November 2020

The epidemiology of MRSA has evolved considerably. In the past, MRSA strains could be traced back to a hospital or clinic source, but over the years there appear to be a decrease in hospital acquired MRSA and an upsurge in the occurrence in community acquired strains. Even-though in Nigeria there are studies that have reported on the molecular characterization of MRSA, Sadly, not much effort has been put into analysis and submission of sequenced data to Gene repositories. Based on information available to us, this is the first study to have successfully deposited nucleotide sequences of MRSA strains from Sokoto state owned Hospital into the Genbank database. Sequence reads of Molecular characterization should be deposited into Gene repositories database by researchers to further populate the database and improve the efficiency of local phylogenetic analysis to foster better bioinformatics as paucity of local data exists in these databases.
DiGeorge syndrome and anomalous right aortic arch with arch-on-arch and figure-of-eight configurations
Authors: Malakan Rad Elaheh , Momtazmanesh Sara
Published: November 2020

We report a 6-month-old female infant with deletion of chromosome 22q11.2 (DiGeorge/VFS TUPLE 1), normal atrial arrangement with concordant atrioventricular connection, pulmonary atresia, large subaortic ventricular septal defect, diminutive native pulmonary arteries, a characteristic weird-shape right aortic arch with arch-on-arch appearance and figure of 8 configuration. We presented the cardiac computed tomographic angiographic and cardiac angiographic features. Using Autodesk 3ds Max 2018 software, we explained and illustrated the speculative embryologic etiology of this bizarre aortic archanomaly with the extensive abnormal remodeling of the left brachiocephalic artery, based on a “five-embryonic aortic arches” concept. As to the best of the authors' knowledge, this is the first report of a genetically confirmed case of DiGeorge syndrome and an exceedingly rare type of right aortic arch anomaly with embryologic explanation according to the “five-embryonic-aortic-arches” concept. It seems that the constellation of pulmonary atresia, bizarreshaped right aortic arch due to abnormal development of the aortic sac, and abnormal remodeling of the left brachiocephalic artery may be strongly suggestive of DiGeorge syndrome.

MATHEMATICAL MODELING OF ASSET LIABILITY MANAGEMENT IN BANKS USING GOAL PROGRAMMING AND AHP
Authors: Tanwar Jyoti , Vaish Arun Kumar , Rao N V M
Published: November 2020

Asset Liability Management has gained popularity in the banking sector. Earlier banks focused on asset allocation, but now the management of assets and liabilities is equally essential. Asset liability management targets the optimum distribution of funds in assets and managing liabilities so that banks can earn higher profits and minimize risk. In this paper, the optimization of assets and liabilities of Indian banks has been concentrated using mathematical models. Combining the Analytical Hierarchy Process (AHP) and Goal Programming (GP) model has been used to solve the optimization problem. AHP is a multi-criteria decision-making approach for deriving priority weights. Goal Programming is a linear programming model to solve complex issues having multiple objectives. In this paper, the primary data gathered from Bank senior managers have been analyzed using the AHP approach to derive weights for criteria. These weights are assigned to goals in goal programming to prioritize the goals. Secondary data on OBC bank is used in goal programming from 2010-2019 collected from OBC bank's annual reports and RBI websites. The findings show that OBC bank has the scope of improving its assets and liabilities position to increase its profit and minimize the risk. The model generates an optimum balance sheet that achieves the set goals and satisfies all the statutory and planning constraints. The same model can be useful for scheduled commercial banks in India with modifications concerning banks' targets and controls. The model developed in this paper is helpful for bank managers in planning and forecasting. AHP and GP's combined approach is unique in this paper, which uses experts' knowledge and applies it in the model. The model is created on the bank's realistic goals and constraints after carefully considering the issues faced by bank officials. The paper is limited to the Indian Banking system as other countries have different balance sheet structures and constraints.

New generalized height-diameter models for birch in European Russia
Authors: Lebedev Aleksandr
Published: November 2020

Height and diameter at breast height are basic variables that are measured in a forest inventory. Generalized models do not require measuring tree heights or number of measurements is minimal. The purpose of this study was to obtain 24 new generalized height-diameter models based on simple basic models, compare them with 9 generalized models selected from other studies, and develop an appropriate height-diameter model for birch in the European Russia. To select models which better describe the relationship between the heights and diameters of the trees, six metrics were used – root mean square error (RMSE), mean absolute percentage error (MAPE), coefficient of determination (R2), adjusted coefficient of determination (R2-adj.), Akaike information criterion (AIC) and Bayesian information criterion (BIC). Results show that there are slight differences between all models. The performance statistics showed that model M24 is the most suitable and recommended for predicting the height-diameter relationships for birch trees in this study area. The predicting variables for applying developed generalized models to estimate total tree height require less sampling effort and are derived from conventional forest inventory data which allows to reduce costs and time consumption in field work.

Authors: De Lima Souza Tatiana , Emanuely da Silva Silvia
Published: November 2020

O Centro de Referência de Assistência Social é um espaço onde se insere o Serviço Social, o qual na atual conjuntura passa por um processo de precarização e perda de direitos, rebatendo no cumprimento das atribuições privativas e competências inerentes ao exercício profissional. Durante o estágio obrigatório observou-se que a área da Assistência Social ainda é permeada pelo conservadorismo e o Serviço Social desenvolve um trabalho que busca reafirmar e viabilizar os direitos daqueles que necessitam. Esse trabalho objetiva analisar o exercício das competências e atribuições privativas do Assistente Social no Centro de Referência de Assistência Social. A metodologia consistiu de estudo bibliográfico e observação participante. Os resultados revelaram que as contradições existentes como, baixos salários, condições de trabalho insalubres e a existência de correlação de forças rebatem diretamente no cotidiano da atuação profissional. Em virtude disso, o Assistente Social enfrenta alguns limites no exercício das competências e atribuições que o norteiam, chegando a se distanciar dos valores defendidos bem como de outros documentos que balizam a profissão. Portanto, constatamos que alguns profissionais que trabalham nos Centro de Referência desconhecem quais são seus deveres e acabam desempenhando atividades que não dizem respeito à profissão. Esse cenário contribui para que não ocorra a qualificação das demandas, reflexões acerca da sua prática e da realidade dos usuários.

Propósito | El objetivo del presente estudio es suprimir identificar los factores que pueden ofrecer a los estudiantes de diseño, las capacidades necesarias para desarrollarse plena y responsablemente en el contexto laboral, uno en el que la opción de trabajar para alguien más, no sea más su objetivo, sino la creación de proyectos personales, participativos y en búsqueda del bien común. Método | Los resultados aquí expuestos se sustentan en el trabajo y la investigación que he realizado durante los últimos dos años impartiendo la materia de CoDiseño – Diseño Colaborativo en el CIDI+UNAM y recientemente en la materia de Innovación y Modelos de Negocio en el ITAM. Aunado a mi experiencia como docente, presento la investigación que sustenta mi práctica educativa y que a su vez permea los objetivos, el diseño y la implementación de los curso que facilito. Parte sustancial de mi quehacer consiste enseñar a los estudiantes a usar y adaptar herramientas que les faciliten la Investigación Basada en la Comunidad, el Análisis Cualitativo Consensuado y la Elaboración Colectiva de Ideas. De esta manera, los alumnos, aprenden a construir sondas, prototipos y otros artefactos para ejercer el proceso de diseño, desde una perspectiva participativa. Resultados principales | Se exponen seis consideraciones estratégicas que estructuran un marco teórico y metodológico para el desarrollo de proyectos educativos que busquen la creación de nuevas comunidades o el fortalecimiento de comunidades previamente existentes: (1) el diseño de planes de estudios flexibles y permeables a las necesidades y aspiraciones de los estudiantes, (2) el cambio de enfoque que implica diseñar procesos e interacciones en vez de producto materiales, (3) la procuración de nuevos y mejores satisfactores, (4) la identificación de la producción a escala humana como principio de la creación de bienes y servicios regenerativos que satisfagan las necesidades de los múltiples involucrados en el proyecto, (5) la integración de dinámicas participativas que vinculen a los estudiantes con personas ajenas a la universidad y (6) el diseño de herramientas mentales, materiales, digitales y espaciales que propicien el intercambio de experiencias y conocimientos.

The paper shows some physical properties of sessile oak obtained in Kosovo regions.

In the study are shown: wood shrinkage, specific gravity, shrinkage coefficient for 1% change of moisture content, ratio of shrinkage in tangential and radial direction etc.

The amount of volumetric shrinkage of sessile oak is 15.95%, heartwood part has an average shrinkage 15.41% in

The shrinkage of sapwood part is 17.56%. Specific gravity at: wet condition: (1.013gr/cm3); 12% (0.853gr/cm3) and 0% (0.826gr/cm3) of moisture content.

Specific gravity of heartwood at: wet condition (1.05gr/cm3); 12% (0.88gr/cm3); 0% (0.85gr/cm3). The specific gravity of sapwood at: wet condition (0.91gr/cm3); 12% (0.77gr/cm3); 0% (0.748gr/cm3).

The ratio of average shrinkage between tangential and radial cutting direction is 1.71%. This ratio was significantly higher in sapwood than heartwood.

Coefficient of shrinkage (changing 1% of moisture content) in the radial direction is 0.00196, and 0.00323 in tangential direction.

Published: November 2020

Purpose: Review on surgical affections of respiratory system and thoracic cavity in dogs

Findings: There are many surgical conditions which are conducted on respiratory system and thoracic cavity in dogs. Among these, Brachycephalic dog syndrome, tracheotomy, tracheostomy, tracheal anastomosis, thoracotomy, thoracocentesis, and preicardioectomy. Before conducting any surgical condition, the nature and extent of the respiratory tract should be examined including historical information, suggestive signs of respiratory tract abnormalities, intended use of the animal, prognosis, complication, availability of the equipments, over all preoperative assessment and economic feasibility should be considered. In addition, the physical examination should include evaluation of regional symmetry of the head, neck, and thorax; evaluation of nasal airflow and patency; palpation of the nasal septum, larynx, and trachea; examination for surgical scars auscultation and percussion. Following thorough and systematic examination of the animals at rest, during and following motion may be warranted. Special examination techniques, including endoscopy, stress evaluation, and radiography, may be indicated.

Unique Contributions to Theory Practice and Policy: Even though there are many physiological derangements due to surgical intervention in respiratory system and thoracic cavity in dogs, it may be healed through primary and secondary intention of healing under aseptic surgical condition. There are also many post operative cares for animals’ undergone surgical activity on respective and specific organs.
Challenges in teaching intercultural communication (ICC) for healthcare students

Including the intercultural aspect in classes can pose great challenges for ESP teachers. First of all, when we try to find the balance between language learning and improving intercultural competence, we may face various problems on how to support both without the two counteracting one another. Furthermore, we must see and acknowledge our competences and responsibilities when teaching communication as ESP teachers. Lastly, we have to be knowledgeable in how to gradually improve intercultural communication among learners with different language proficiency levels. In our paper we aim to find answers to these questions based on our experience in teaching intercultural communication to health service manager students.
Kossuth nyelvismerete és nyelvhasználata
Authors: Sturcz Zoltán
Published: November 2020

A XIX. század első felében a magyar politikai, társadalmi elit és az értelmiség körében természetes jelenség volt a többnyelvűség. Ezt a jellemzőt részben a nemesi vagy polgári családi kör, részben a soknemzetiségű és egyben soknyelvű magyarországi társadalom, részben az iskolarendszer hozta magával. A latin nyelv az iskolarendszer oktatott és egyben oktatási nyelve is volt, de a jogi, a közéleti, a politikai pálya meghatározó nyelveként is működött a birodalomban elvárt német nyelv mellett. Kossuth a reformkor, a forradalom, a szabadságharc nagy alakja szintén egy többnyelvű generáció tagjaként élt, és ezt a többnyelvűséget az emigráció éveiben tovább bővítette. Nyelvhasználata több mint tíz nyelvre és nemcsak a köznyelv világára terjedt ki, hanem a szaknyelv különböző területeit is kiválóan művelte. Ezek közé a területek közé tartoztak a következő szaknyelvi világok: jog, publicisztika, diplomácia, természettudományok bizonyos szakágai. Nagy retorikai teljesítményei mellett az anyanyelv tudatos fejlesztőjeként a nyelvművelés területén is tevékenykedett. Kossuth nyelvismerete több nyelvpedagógiai szempontból is vizsgálható, úgymint: autodidakta nyelvtanulás, természetes elsajátítás, nyelvfejlesztés, a nyelvek ismeretének kölcsönhatása, nyelvpolitika. A téma bemutatása egy nagyobb ívű reformkori oktatástörténeti, nyelvoktatás-történeti kutatómunka része.
