Published: April 2021

The urgency and significance of the application of the ontological approach in teaching computer-aided design is substantiated. Training and retraining of personnel is one of the important stages in the implementation of automated systems for industrial purposes, and methodological support tools are necessarily present in the portfolio of all leading manufacturers of computer-aided design systems (CAD). Principles and approaches to the formation of the ontological base of the subject area of teaching computer-aided design are proposed. To highlight the structure of educational ontology, it is proposed to use the concepts of aspects of mechanical engineering design. The hierarchy of levels of training for CAD users is determined. At the operator level, training comes down to mastering a limited set of terms and concepts implemented in specific system solutions. At the technician level, it is required to master a wider set of standard design procedures typical for a whole class of basic CAD technologies. At the engineering levels, the user acquires the knowledge necessary to master the technologies and CAD tools in the complex of all stages of technical preparation of production. The article describes the method of ontological analysis of the studied subject area, which ensures the formation of target trajectories for training and retraining specialists, providing for a number of sequential stages in the formation of an ontological base. The article describes the method of ontological analysis of the subject area of education, which ensures the formation of target trajectories of training and retraining of specialists and provides for a number of successive stages of the formation of an ontological base. To optimize the individual trajectories of training CAD specialists, special software has been developed, integrated with the Protégé ontological editor.

Authors:   Kuban State University, Kostenko K. , Belkin V. ,   Kuban State University
Published: April 2021

A model of an intelligent system is proposed for implementing the control and professional use of a knowledge collections related to subject area of software interfaces with external users. The basis of formalization is an abstract model of an intelligent system. It is based on coordinated and balanced invariants of the knowledge representation formalism model. Invariants set includes classes of morphisms for abstract knowledge processing modelling with morphisms' domains, invariants of the multidimensional architecture of intelligent systems components, which includes intercomponent knowledge flows and processes of knowledge synthesis within components, as well as invariants of control agents for abstract knowledge flows and processes within intelligent systems. The intelligent system knowledge base is presented as subject area ontology by non-ordered series of simple knowledge. Fragments of such ontology are distributed between components of intelligent systems three-dimensional architecture. The basis of such structure based on the dimensions of abstraction, structuring and the level of knowledge addressed to and processed within intelligent system's separate components. The ontologies reflect the ideas about the structures of memory and the processes of thinking used to model the schemes of the professional activity of a specialist. The basis for the formalization of such concepts is the fundamental principles of philosophy, linguistics, cognitive psychology, mathematics, and system engineering. This allows deploying a comprehensive system of classes of information structures and processes for complex knowledge synthesizing that support achievement of various cognitive goals implemented by specialists within professional tasks implementation processes. The goals system includes extraction, analysis and application of knowledge about user interfaces. The variety of such goals is modeled by a high-level implementation pattern system. They are composed of basic types of goals and are implemented using knowledge processing cognitive operations. Knowledge structures in the format of semantic hierarchies are used as a unified representation of knowledge. Cognitive goals are realized by combinations of operations on structured knowledge, adapted to special classes of structures.

Authors:   Institute of Solid State Chemistry of the Ural Branch of RAS, Istomina Aigul S. , Bushkova Olga V. ,   NTI Competence Center of the Institute of Problems of Chemical Physics of RAS
Published: April 2021

The third part of the review is devoted to polymer binders with electronic conductivity used to make composite electrodes for lithium electrochemical systems. Polymer semiconductors (“synthetic metals”), related polymers with additionally introduced functional groups, related copolymers and mixtures of polymers, as well as carbon chain polymers and copolymers with inсorporated polyaromatic fragments are considered. Such materials significantly improve electrical connectivity of the composite electrode and make it possible to eliminate or minimise the content of electrochemically inert conductive additives (carbon black, graphite powder), which positively influences on the specific capacity and cycling stability of the electrodes. Improving conditions of electronic transfer is especially important for the efficient use of active materials with extremely low intrinsic conductivity, such as Si, Li4Ti5O12, LiFePO4, etc. The final part of the review summarizes general principles of the targeted selection of a polymer binder.

Formats and genres of media communication of the executive power
Authors:   Perm State University, Shirinkina Mariya A.
Published: April 2021

The article presents a general description of the system of the executive power media resources from the point of view of its genre organization. The author offers a literature review on computer-mediated communication and the sphere of public relations and gives a definition of a genre in connection with the Internet. It is argued that an important characteristic of a media genre is its format regarded as a sum total of discourse and media aspects determined by the technical capacity of various Internet services. On the basis of executive power official websites, their press service publics and accounts of individual officials in social networks and microblogging services (VK, Instagram, Twitter), as well as messenger channels (Telegram) the author singles out genre varieties of media messages. The author argues that the executive power media communications form an integrated system of communication means and methods of communicating with the society through various Internet services and platforms. The complex of multi-code media messages constitutes a scenario of communication with all possible target groups of the state with a view to create in the collective consciousness a positive image of the executive branch in general and that of the individual officials in particular. The author comes to the conclusion that, when a communication product is posted on the Web, its principal genre features (volume, theme, composition, stylistic peculiarities) remain recognizable, and only the form of presenting the information offered to the addressee with the help of different semiotic systems varies: text, video, photo, animation, music, graphics and infographics as its particular mode, etc. The research of categorical and textual approach to media genres, which allows to describe their typological characteristics in detail may be regarded as a promising continuation of this study.

Published: April 2021

Introduction: Acute myocardial infarction (AMI) is a leading cause of death and disability worldwide. Determining seasonal pattern of AMI may contribute to disease prevention and better treatment.
Objective: The present study was conducted to investigate daily, monthly, and seasonal pattern for symptoms҆ onset in the patients with ST-segment elevation myocardial infarction (STEMI), and also other possible associated factors.
Methods: This cross-sectional study was conducted on 777 patients diagnosed with STEMI admitted at the Imam Ali Cardiovascular Hospital affiliated with Kermanshah University of Medical Sciences (KUMS), Kermanshah province, Iran from March 2018 to February 2019. Data were collected using a checklist developed based on the study's objectives. Differences between subgroups were assessed using one-way analysis of variance (ANOVA) followed by Tukeys҆ post‐hoc test and Chi-Square test (or Fishers҆ exact test).
Results: Out of 777 patients, 616 (79.3%) of them were male. Mean age of the patients was (mean±SD) equal to 60.93±12.86 years old. Occurrence of STEMI was most common in winter (38.4%), followed by autumn (27.8%), spring (22.9%), and summer (10.9%), respectively. Monthly occurrence of AMI was at the highest level in January (10.8%) and December (9.9%), and it was at the lowest level in July (4.9 %). Most patients were admitted on Fridays (15.8%) and Wednesdays (15.6%). Hypercholesterolemia, prior congestive heart failure (CHF), prior MI, prior stroke, prior atrial fibrillation (AF), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides, total cholesterol, creatine phosphokinase (CPK), and creatine kinase myocardial band (CK-MB) were significantly associated with seasonal pattern of STEMI (p-value<0.05).
Conclusions: Results of the present study on Iranian patients with STEMI revealed that AMI occurred more frequently on Wednesdays and Fridays and during winter from December to January compared to the other days of the week, months, and seasons.

Published: April 2021

Introduction: Considering that hemorrhagic stroke patients are at higher risk for bleeding, administration of higher doses of melatonin with a controversial coagulation profile is a serious concern.
Objective: This study aimed to investigate the possible effects of high doses of melatonin on bleeding parameters and blood hemostasis in hemorrhagic stroke patients.
Methods: This study is a randomized, double-blind, prospective, controlled trial. Confirmed hemorrhagic stroke patients were divided into two groups. Participants were randomly assigned into the melatonin group (30 mg daily via gastric tube gavage for 5 consecutive days) or the control group. Each patient was monitored for 5 days, and 2 blood samples were taken and the effect of the intervention on coagulation factors and blood hemostasis were investigated.
Result: In total, 30 patients were randomly assigned to melatonin (n=15) or control groups (n=15). there was no significant difference between the two groups in demographic and clinical characteristics. There was a significant decline in prothrombin time (PT) and fibrinogen levels in the melatonin group (p=0.011 & p<0.001, respectively). P-values for VII and VWB factors showed a significant increment in these two factors in the melatonin group after the intervention (p=0.035 & p=0.002, respectively). No significant changes in serum levels of D-dimer factor, APACHE II, and GCS scores were evident in the two groups after the intervention (p>0.05).
Conclusion: Considering the favorable changes in coagulation parameters observed in this study, it could be concluded that melatonin can have both procoagulant and antithrombin properties.

Introduction: Uterus didelphys with obstructed hemivagina associated with ipsilateral renal agenesis (OHVIRA syndrome) is a rare female urogenital malformation and delay in its diagnosis could lead to several complications.
Case presentation: A 21-year-old virgin woman was admitted to the emergency department (ED) with severe abdominal pain, without fever and vaginal discharge. She reported a history of cyclic abdominopelvic pain and dysmenorrhea for 5 years. The primary diagnosis (OHVIRA syndrome) was made using ultrasonography, spiral computed tomography (CT) and magnetic resonance imaging (MRI). In addition, laparoscopy was performed to confirm diagnosis and drain hematosalpinx. Then, hysteroscopy was carried out for septum resection and catheter insertion. At one-month follow-up the ultrasonography showed normal left hemicavity of uterus associated with significant decrease in dysmenorrhea.
Conclusion: Being aware of OHVIRA syndrome and clinical suspicion of this rare anomaly are essential for making a timely diagnosis, preventing complications, relieving symptoms, and preserving future fertility.

ETNOCONHECIMENTOS SOBRE ANIMAIS DE PESCADORES ARTESANAIS NA AMAZÔNIA COSTEIRA PARAENSE
Authors: Santos Claudia Nunes
Published: April 2021

A diversidade faunística, bem como a diversidade humana da Amazônia tem sido estudada por diversos especialistas em busca da compreensão das formas de vida e evolução do sistema. Para superarmos os limites das interpretações produzidas, além de unirmos diferentes ferramentas, técnicas e abordagens das diversas disciplinas da ciência, precisamos considerar as subjetividades pertencentes a este complexo. Os conhecimentos locais, tradicionais ou etnoconhecimentos dos diferentes povos e comunidades ampliam a visão sobre a sociobiodiversidade da região. Um dos esforços que orientam a Etnobiologia é a ruptura como um modo de fazer ciência, que separa sociedade e natureza, bem como a compreensão de que o conhecimento é construído na relação entre pessoas pesquisadas e que pesquisam. Apresento aqui algumas inferências conservacionistas das interações entre pescadores com tartarugas marinhas e aves costeiras. As pesquisas foram realizadas entre 2015 e 2018, em seis comunidades de pescadores nos municípios Bragança, Tracuateua e Salinópolis, no estado do Pará. As ricas etnozoologias e etnotaxonomias de pescadores artesanais sobre tartarugas-marinhas e aves-costeiras locais revelam um conhecimento aprofundado sobre estes animais que não são de interesse para o autossustento. E ainda, a consciência dos pescadores quanto à importância dos animais para os ecossistemas são etnoconhecimentos importantes para o entendimento das relações humanos-animais, bem como para ações de preservação e manejo localmente referenciadas.

Examining Student Regulation of Collaborative, Computational, Problem-Solving Processes in Open-Ended Learning Environments
Authors: Emara Mona , Hutchins Nicole , Grover Shuchi , Snyder Caitlin , Biswas Gautam
Published: April 2021

The integration of computational modelling in science classrooms provides a unique opportunity to promote key 21st century skills including computational thinking (CT) and collaboration. The open-ended, problem-solving nature of the task requires groups to grapple with the combination of two domains (science and computing) as they collaboratively construct computational models. While this approach has produced significant learning gains for students in both science and CT in K–12 settings, the collaborative learning processes students use, including learner regulation, are not well understood. In this paper, we present a systematic analysis framework that combines natural language processing (NLP) of collaborative dialogue, log file analyses of students’ model-building actions, and final model scores. This analysis is used to better understand students’ regulation of collaborative problem solving (CPS) processes over a series of computational modelling tasks of varying complexity. The results suggest that the computational modelling challenges afford opportunities for students to a) explore resource-intensive processes, such as trial and error, to more systematic processes, such as debugging model errors by leveraging data tools, and b) learn from each other using socially shared regulation (SSR) and productive collaboration. The use of such SSR processes correlated positively with their model-building scores. Our paper aims to advance our understanding of collaborative, computational modelling in K–12 science to better inform classroom applications.
Collaboration Analytics Need More Comprehensive Models and Methods: An Opinion Paper
Authors: Han Areum , Krieger Florian , Greiff Samuel
Published: April 2021

As technology advances, learning analytics is expanding to include students’ collaboration settings. Despite their increasing application in practice, some types of analytics might not fully capture the comprehensive educational contexts in which students’ collaboration takes place (e.g., when data is collected and processed without predefined models, which forces users to make conclusions without sufficient contextual information). Furthermore, existing definitions and perspectives on collaboration analytics are incongruent. In light of these circumstances, this opinion paper takes a collaborative classroom setting as context and explores relevant comprehensive models for collaboration analytics. Specifically, this paper is based on Pei-Ling Tan and Koh’s ecological lens (2017, Situating learning analytics pedagogically: Towards an ecological lens. Learning: Research and Practice, 3(1), 1–11. https://doi.org/10.1080/23735082.2017.1305661), which illustrates the co-emergence of three interactions among students, teachers, and content interwoven with time. Moreover, this paper suggests several factors to consider in each interaction when executing collaboration analytics. Agendas and recommendations for future research are also presented.

Authors: Svarich V. G. , Kagantsov I. M. , Svarich V. A. , Perevozchikov E. G.
Published: April 2021

Introduction. The first publications about acute appendicitis in the conditions of the new COVID-19 coronavirus infection have appeared. Most authors point to the increased time of seeking medical help in such patients and an increase in the level of postoperative complications.Material and methods. A retrospective study of 192 case histories of patients aged 3 to 17 years with various forms of acute appendicitis who were treated in the surgical Department of the Republican children’s clinical hospital in the period from 2019 to November 2020 was conducted. Children operated on during 2019 before the start of the new coronavirus pandemic were included in the first group (n = 114). Children operated on in 2020 after the development of a new coronavirus pandemic were included in the second group (n = 78).Results. The age of patients in both groups compared did not differ significantly. The course of the disease was within the average accumulated indicators and the terms of hospitalization did not change significantly. According to our observations, the time of admission to the surgical hospital from the time of the disease in the pre-coronavirus period and during it also did not differ significantly, which indicates that the same availability of medical care remains even during the epidemic. Our study also showed that the number of requests for complicated appendicitis in children during the COVID-19 epidemic even decreased, which ultimately led to a decrease in the level of postoperative complications. The study did not establish a significant difference between the main results of treatment of children with acute appendicitis before and during the new COVID-19 coronavirus infection. Only the level of postoperative complications significantly decreased in patients operated during the COVID-19 epidemic, which is associated with a lower admission of children with complicated appendicitis.Conclusion. With the onset of the pandemic, the organization of medical care for the child population with acute pathology in the Komi Republic did not change and did not have any restrictions, which made it possible to maintain the timely provision of surgical care to children with acute appendicitis at the proper level.

Introduction. Pyloric atresia is one of the rarest surgical diseases in newborns. Laparotomy is the most common modality for correcting this abnormality. In modern scientific literature, there is only one report on the endosurgical treatment of pyloric atresia. The case of laparoscopic correction of gastric outlet atresia presented in this study is one more reference to the successful care of this condition.Material and methods. The presented clinical case is a newborn boy in whom a prenatal ultrasound examination at the 31st week of gestation revealed polyhydramnios and an enlarged stomach. The baby’s birth weight was 2660 grams. In the first hours of life, the child showed symptoms of high intestinal obstruction in the form of gastric content vomiting. Postnatal ultrasound and X-ray examination confirmed the diagnosis of pyloric atresia. During laparoscopy, performed on the 2nd day of life, the morphological type of anomaly was examined, and the type I atresia of membranous form was established. A laparoscopic membranectomy with Heineke–Mikulicz pyloroplasty was performed. In the final part of this research, early and late outcomes of the performed surgical treatment were analyzed.Results. The surgery lasted for 70 min. Postoperative period was uneventful. Enteral nutrition started on day 3 after the surgery. A complete enteral diet was possible on day 7. The newborn patient was discharged from the hospital on the 9th postoperative day. Histological examination confirmed the pyloric atresia of membranous type. During 12-month follow-up, no complications associated with the surgical procedure were seen.Conclusion. The described case of laparoscopic treatment of type I pyloric atresia in a newborn expands laparoscopy application in pediatric practice.
“Banuroja” (One Village with Three Religions): A Model of Social Harmony in Gorontalo
Authors: Faisal Ahmad
Published: April 2021

Banuroja is an acronym for “Bali, Nusa Tenggara, Gorontalo and Java”. From its naming identity, it appears that the community is heterogeneous both in terms of ethnicity, language, culture and religion. The heterogeneity of the people of Banuroja Village is actually an element that strengthens the harmony between them. There does not appear to be arrogance from followers of a particular religion, there is no excessive militancy, there is no intrigue to negate each other. This study shows that there are five aspects which are the key words of the Banuroja social harmony, namely (1) aspects of education and youth; (2) aspects of settlement and tradition; (3) aspects of work; (4) aspects of village government institutions; and (5) other aspects such as the prominent figures / religious elites. The driving aspects of integration on the one hand are actually at the same time a trigger for conflict on the other side. The author argues that the people of Banuroja have succeeded in showing that harmony is not just passive co-existence, not an artificial harmony. Living in diversity, in the context of Banuroja, actually being actualized by active co-existence in intimate friendship dissolves in the specialness of each rite without denouncing the other rites.
VULNERABLE ELECTRICALLY CHARGED SARS-COV-2 POINTS, ELECTRIC MODEL OF THE VIRUS AND ROLE OF TRACE ELEMENTS IN ITS INACTIVATION

Published: April 2021

In the review article, electrically charged molecular groups on the surface of the virus were considered as targets for antiviral agents. The prospects of trace element application in a low oxidation state as antiviral agents have been shown. An electrical model of SARS-CoV-2 has been developed in the form of a multilayer structure, where each shell corresponds to electrically charged proteins on the surface of the virus. The model reveals the role of Coulomb forces in adsorption and fusion processes and makes it possible to identify vulnerabilities in the coronavirus that are sensitive to electrically charged substances and to an electric field. The mechanism of antiviral action of trace elements is disclosed, based on the suppression of electrostatic interaction of virus with the cell by neutralizing the charges on the surface of the virus and the cell. This allows the selection of oligopeptides and trace elements in low oxidation states to suppress the adsorption capacity of viruses. The special role of trace elements is that many potential targets that are inaccessible to antibodies and other large molecules are easily available to trace elements.
ESSENTIAL TRACE ELEMENTS: POSSIBLE ROLE IN THE ETIOPATHOGENESIS OF AUTISM SPECTRUM DISORDER AND SPEECH DEVELOPMENT DELAY IN CHILDREN OF DIFFERENT AGES
Authors:   First Sechenov Moscow State Medical University, Chernova L.N.
Published: April 2021

An imbalance of trace elements plays a significant role in the etiopathogenesis of Autism Spec-trum Disorder (ASD) and Speech Development Delay (SDD). The aim of the study was to analyze an essential trace elements content in the hair samples of children with ASD and SDD for better understanding age and gender related diversity. The study included 258 children with ASD and 239 children with SDD. Control group consisted of 620 healthy children of similar age. All children were divided into two age categories (1.5 to 3 years old and 4 to 13 years old). It was shown that girls with ASD had more deviations in hair essential trace elements levels than boys. Children with ASD and SDD (1.5 to 3 years old) had significantly decreased hair iodine level (by 48-58%, p < 0.0001). Low iodine level can be a significant indicator of mental and speech development delay. Normalization of hair iodine level in older boys with ASD accompanied by significant decrease in hair cobalt level (by 24%, p = 0.0001) may reflect age-related characteristics of iodine and cobalt metabolism. Low hair manganese level (by 12-44%, p < 0.05) was observed in all groups of children. It’s possibly associated with decreased manganese excretion from the body and can provoke manganese-induced neurotoxicity. The decrease in copper levels in girls of different ages (by 9-17%, p < 0.01) is probably influenced by hormonal status and earlier onset of puberty.

Some Methodological Problems of Contemporary Economic Comparative Studies
Authors: Toganova N.
Published: April 2021

The author analyses the methodology of comparative studies used by the English and German speaking specialists in the 1950-1980th. With the collapse of the Communists block it seemed that such studies could become outdated because, as some scholars reasoned, economic systems started to lose their peculiarities and to drift in the same direction. Two decades after it can be stated that this didn’t really happen. Comparative studies still have the reasons to be continued. At the same time, there still remain questions concerning their methodology. That is why a review of the methodology approaches is of prime interest of the article. The author starts from consideration of the question of the interaction between comparative studies and economic theory. This analysis is vital not only for the whole research field. It also helps to better understand the difference in Anglo-Saxon and German research approaches to comparative studies. The scholars from USA and Great Britain never paid special attention to this topic. On the contrary, some prominent German researchers attempted to produce a working theory of international comparisons. Further, the author reviews the evolution of the main approaches. The following phases are found: the conceptualization of theoretical approaches how different economic systems were set and how they could be compared; inter-comparison of existing and ideal systems drawn by the theorists; development of the institutional approach and the growing popularity of comparisons through quantitative indicators and later through institutions (rankings and top lists of countries). The final part of the article provides a detailed analysis of German approach to the comparisons of economic systems.
Russia and Austria: Mutually Beneficial Cooperation and its Prospects
Authors: Vasil'ev V.
Published: April 2021

The aim of this article is to explore political aspects of Russian–Austrian relations in the conditions of globalization and European integration, and the factors contributing to the advanced development of multidimensional interaction between Moscow and Vienna. The paper deals with approaches taken by the Government and the main parties in Austria to the policy in Russian direction; it also singles out the trends of the bilateral partnership widening. An important element consists in the analysis of image formation of contemporary Russia and Austria. For Austrians, the quality of Russia’s political setup and its socio-economic model is determined by the existence of a real multi-party system, competitiveness between parties in elections and objective summing up of voting returns, natural change of elites, efficiency of various sectors within economy, and the degree of effort aimed to combat corruption. Vienna is criticizing Moscow for actions, which, as seen by Austrian experts, are a violation of human rights and freedoms and constrict the opportunities for development of civil society in Russia. Analysis reveals that the political dialogue is a pragmatic foundation for diverse bilateral links. Stability and reliability of Russian–Austrian relations is confirmed by regular contacts at the top and high level, intensity of cross-sectoral consultations, building up of inter-parliamentary relations and strengthening of fruitful cooperation between regions and cities of the two countries. The trade and economic dimension of bilateral relations imply an incremental cooperation between Moscow and Vienna because Austria’s achievements in innovative, high-tech and other fields, on one hand, meet Russia’s needs in modernizing its national economy and, on the other hand, ensure the sales of Austrian export items in Russian markets as well as safeguard the continuous prosperity for citizens of the Alpine Republic. Cultural and scientific ties as a value factor in bilateral relations testify to the natural attraction of people in both countries and create favorable prerequisites for a dialogue on the issues of common European values. The Austrian experience is of major scientific and practical interest in many respects. Present-day theory and practice of Austria’s governmental and party construction point to the democratic opportunities of involving of various population sections in political competition, and a joint quest for a compromise between different regions, political forces and ethnic groups. The institution of social partnership seems useful. Rich experience of cooperation, high degree of confidence at the political level, long-lasting mutual likes between Russians and Austrians allow one to speak in terms of an unique creative potential of Moscow and Vienna that is successfully implemented in various spheres of socio-political life.
Foreign Investment Regulation in Canada

Published: April 2021

The article analyzes recent changes in the principles, mechanisms and practices of the FDI regulation in Canada. Since 2010, this country has been rated by the international experts as one of the best places to invest. Most of the recent FDI is flocking into the country’s resource sector – in particular into mining and oil and gas. At the same time, there’s been a radical shift in the origins of the FDI. The state-owned corporations and sovereign funds from the Asian emerging markets, mostly from China, are demonstrating their willingness and readiness to become the major foreign investors in the Canadian resource sector.
Paradigm of Human Development in Spain

Published: April 2021

Main trends of human development in Spain in 1975–2013 are considered. The present high level of HDI, in particular in education, was achieved by this country for the years of its democratic transformation. Education in Spain has begun to play a considerable role since the beginning of the 1980th as a result of a number of its profound reforms. Аn unprecedented growth of students enrolled in schooling of different grade levels mostly in the secondary and higher education with subsequent rapid increase of HC accumulation. If earlier the main factor of the country’s economic development was the growth of its population with the dominant labor force of initial education level, by now the most representative group has become the people with secondary and higher education. Another impressive trend is the rapid growth of both female education and employment. It permits considering this gender group as a fundamental basis of the country’s present and future labor force. Despite its achievements Spanish education system is still relatively weak and having a number of serious deficiencies in comparison with the leading OECD countries. Without further education reforms Spain won’t be able to change its economic model, increase its labor force quality and to continue moving ahead on the way to social progress.

The aim of the present study was to evaluate and to compare the physicochemical composition of egg white, and to characterize and estimate the quantitative variations of egg white proteins of different birds’ species (duck, quail, Chicken, partridge and goose). For each bird species, the whole egg temperature, weight, height, density and shape index were evaluated. After breaking the eggs, a visual examination was performed then vitelline (VI) and albumen (AI) indexes and the haugh unit (HU) were measured. The study of the quality and the characterization of egg white proteins were performed by Agarose Gel Electrophoresis. The total egg weight varied within a range of (8.98±0.82 g to 142.91±10.34 g) for quail and goose, respectively. The thickness of the egg yolk was almost three times higher than that of the egg white in all breeds. The egg freshness, measured by HU, was higher in partridge, followed by quail and chicken breeds with values of 88.81±0.09, 87.45±3.33, 81.53±2.16, respectively. The VI shows values of about 0.40. The egg yolk/ white ratio ranged from 47 and the pH varied from 8.37 to 8.95 for all local species studied. The egg white protein content was higher for all species (up to 14.45g/100 g). Three types of proteins are identified by agarose gel electrophoresis (ovalhibitor, ovotransferrin and ovalbumin) with a quantitative difference between bird species. Densitometric analysis shows a qualitative difference due to the presence of type C lysozyme in chicken egg white.

The objective of the research was to determine the estrous profile of Etawah Crossbred goats after estrous synchronization with different methods. Eighteen does aged 12-24 month old were divided in three groups to receive estrous synchronization treatments (T1 = 14 days intravaginal implant of 60 mg of progesterone  (MPA), T2 = two times injection of 5 mg PGF2α (lutalyse) in 11 days interval, and T3 = 10 days of intravaginal implant of 60 mg of progesterone  (MPA) + injection of 5 mg PGF2α 48 hours before removal) with six replications. The parameters consisted of estrous behaviour, changes in size and colour of vulva, and duration of estrus when the number of superficial and keratin cells were dominating in the vaginal mucus cell. Data from estrous behaviour and score of vulvar colour was analyzed using Kurkal Wallis test, while onset of estrus, size of vulva slit and estrous duration was analyzed using ANOVA and Duncan test. The result showed that estrous behaviour and changes in color and size of vulva were not significantly different, but estrous duration was significantly different. Estrous duration in T1 (31.30 hour) and T2 (31.10 hour) was significantly longer than that of T3 (11.36 hour). It is concluded that different methods of estrus synchronization affected estrous quality equally but it affected the estrous duration differently based on vaginal mucus cells. Treatment implant vaginal sponge content progesterone for 14 days and double injection of PGF2α with 11-day interval given longest estrous duration.

Artisanal fishing is an important traditional activity on the coast of Espí­­rito Santo (ES) State, southeastern Brazil. Despite this, there is a lack of updated data on artisanal fishing and its interfaces with socioenvironmental oceanography. The present study describes the social profile of fishers (gender, age, education, and period of professional activity) and the fishing activity (fishing gear and target species) along the coast of Espí­­rito Santo State. Interviews with semi-structured questionnaires were carried out with 366 artisanal fishers living in 10 fishing communities. The interviewed fishers are mostly male, with low education, who had been fishing for more than 41 years (32%). The fishers described 59 target ethnospecies, with eight being common in 90% (n = 9) of the communities under study. These workers use the following fishing gear: line, longline, gillnet, trawl net, and harpoon. Socioenvironmental oceanography enables obtaining basic information on artisanal fishing, which can support the development of public policies for the sector with a view to maintaining this activity in Espí­­rito Santo State.
