Synthesizing Realistic Human Dance Motions Conditioned by Musical Data using Graph Convolutional Networks
Authors: Ferreira João P. M. , Martins Renato , Nascimento Erickson R.
Published: June 2022

Learning to move naturally from music, i.e., to dance, is one of the most complex motions humans often perform effortlessly. Synthesizing human motion through learning techniques is becoming an increasingly popular approach to alleviating the requirement of new data capture to produce animations. Most approaches, addressing the problem of automatic dance motion synthesis with classical convolutional and recursive neural models, undergo training and variability issues due to the non-Euclidean geometry of the motion manifold structure. In this thesis, we design a novel method based on graph convolutional networks, that overcome the aforementioned issues, to tackle the problem of automatic dance generation from audio information. Our method uses an adversarial learning scheme conditioned on the input music audios to create natural motions preserving the key movements of different music styles. We also collected, annotated and made publicly available a novel multimodal dataset with paired audio, motion data and videos of people dancing three different music styles, as a common ground to evaluate dance generation approaches. The results suggest that the proposed GCN model outperforms the state-of-the-art dance generation method conditioned on music in different experiments. Moreover, our graph-convolutional approach is simpler, easier to be trained, and capable of generating more realistic motion styles regarding qualitative and different quantitative metrics. It also presents a visual movement perceptual quality comparable to real motion data. The dataset, source code, and qualitative results are available on the project's webpage: https://verlab.github.io/Learning2Dance_CAG_2020/.
Computing Vessel Velocity from Single Perspective Projection Images
Authors: Huillca Jose Luis , Fernandes Leandro A. F.
Published: June 2022

The Master’s Thesis presented an image-based approach to estimate the speed of moving vessels from their traces on the water surface. Vessels moving at constant heading and speed display a familiar V-shaped pattern which only differs from one to another by the wavelength of their transverse and divergent components. Such wavelength is related to vessel speed. We use planar homography and natural constraints on the geometry of ships’ wake troughs to compute vessel speed from single optical images acquired by conventional cameras. Experiments show that our approach produces compelling results, which are in accordance with true data available for the observed vessels.

Obesidade é uma doença crônica que assola diversos países acarretando prejuízos como dificuldade respiratória e do aparelho locomotor, alterações metabólicas, problemas cardiovasculares e até o óbito, no caso extremo. Nessa perspectiva, é avaliar o desempenho dos o objetivo deste estudo inicial classificadores, a saber, Floresta aleatória e Máquina de Vetor de Suporte, ao estimar os níveis de obesidade, com os dados do conjunto "Estimation of obesity levels based on eating habits and physical condition Data Set". Sob a validação cruzada e HoldOut, os resultados preliminares indicam uma média de acurácia com SVM em torno de 87,84% e e RF em torno de 95,18%. Além disso, notamos que nossa abordagem foi capaz de melhor reconhecer os casos de sobrepeso e obesidade. Enquanto que nesses casos, o trabalho mais recente negligencia de forma mais crítica, até mesmo classificando de forma incorreta o grau mais severo de obesidade. Assim, comparando nossos resultados com os trabalhos relacionados, conclui-se que os modelos estudados são adequados ao problema haja vista os resultados atigindos.

Authors: Viti Vinícius Mafra , Marques Bruno Augusto Dorta
Published: June 2022

This research aims to study the feasibility of glasses with a camera as a guide for the visually impaired. This idea will be developed to provide these people a way to "see, feel, and experience" the world in a different way. Thus, the development of such technology will be done employing Artificial Intelligence and Computer Vision resources/software. Some attention is given to visually impaired people, although many still experience great difficulty getting around and living alone, directly impacting their quality of life. Hence, implementing the proposed idea is extremely necessary since it will bring a sense of the environment to those who cannot visualize it and suffer daily. Therefore, the research will consist of conducting an improved study on the best methodology and technology to identify objects in front of blind people. The objective is to identify the most relevant objects, providing distance cues to the visually impaired person.

Published: June 2022

Esse trabalho apresenta um estudo comparativo entre dois modelos de redes convolucionais profundas em tarefas de identificação e contagem de insetos em imagens digitais, considerando afídeos (Hemiptera: Aphididae) e parasitoides (Hymenoptera: Aphelinidae e Braconidae, Aphidiinae). Nesse estudo de caso, cada imagem pode conter centenas de espécimes, detritos, sobreposições e outros insetos com morfologia semelhante, o que dificulta o processo de detecção. Nesse sentido, comparou-se os resultados obtidos pelo sistema InsectCV, baseado em Mask RCNN, em termos de tempo de treinamento, inferência e precisão, com um novo modelo, treinado com a rede DarkNet. Com a utilização de imagens em tons de cinza, com menor dimensão, processamento via GPU e uma rede convolucional de um estágio, é possível a redução do custo computacional e elevação da precisão na tarefa de detecção de objetos. Com base em 580 imagens utilizadas para a validação do modelo proposto foi possível obter a precisão média de 79,9%.

Published: June 2022

Computer games and, of course, the development associated with them have been in the spotlight for many years; recently, also with technologies, such as virtual reality or extended reality. The main part of this chapter presents the classification of collaborative XR systems, the concept of the major application architectures and the consistency models of shared virtual game environments. The next subchapter briefly deals with the sharing of property ownership. The mentioned concepts and examples used in the chapter are implemented in many works and projects using a collaborative environment (also in gamified form) developed in the laboratory LIRKIS, the home laboratory of the authors. The knowledge presented in this chapter may provide tips and inspiration for some other game projects, and practical and useful notes on the advantages or disadvantages of some systems will be interesting and useful.
Interactive Effects of Salinity, Drought, and Heat Stresses on Physiological Process and Selection Criteria for Breeding Stress-Resistant Cotton
Authors: Mehmet Cinar Volkan , Balci Serife , Unay Aydın
Published: June 2022

The cotton crop is adversely affected by the combination of salinity, drought, and heat stress during all growth stages in cultivated areas. The negative impacts of salinity together with water scarcity on osmotic stress dramatically increased the sensitivity of reproductive development. After membrane integrity and signaling networks are depressed under stress at the cell level, the metabolic and physiological processes are disrupted in the next stage. The restricted root growth, ion and water uptake, phloem, photosynthetic and respiratory capacity, incompatible hormonal balance, and reduction in yield due to lower boll retention are the most important symptoms. The seed treatments and foliar applications of osmoprotectant and fertilization appear to reduce multiple stress factors in possible climate change conditions. The osmotic adjustment, antioxidative ability, electrolyte leakage in the membrane, and chlorophyll fluorescence are evaluated as selection criteria for improving genotypes. Direct selection of plants with high yield under stress conditions may increase the success of cotton breeding. It is important to know the molecular approaches and gene functions responsible for abiotic stress. In this chapter, the effects of high temperature, salinity, and drought on cotton plants and characteristics associated with tolerance were focused on cotton improvement. The classical breeding methods and molecular approaches should be combined for breeding new cotton varieties.

Authors: Rakhshani Homeyra , Delavar Reza , Nikoofar Morteza
Published: June 2022

Background: Estrogen deficiency and increasing its reabsorption are determining factors in reducing bone density in postmenopausal women. Objectives: The purpose of this study was to investigate the response threshold of alkaline phosphatase (ALP) and parathyroid hormone (PTH) to resistance training along with calcium and vitamin D intake in postmenopausal women. Methods: In the present study, 17 postmenopausal women (50 - 60 years old) in Zahedan were randomly selected and divided into two groups, exercise + supplement (n = 9) and control (n = 8). The exercise + supplement group received 1,500 mg of calcium and 600 IU daily of vitamin D. Each of them performed resistance training movements in three sets with eight repetitions, with an intensity of 55% 1RM in the first week to 65% 1RM in the fourth week for three sessions/week during four weeks. Sampling was performed before the first training session and 24 hours after the last session from the first to fourth weeks. Data were analyzed with repeated-measures analysis of variance using SPSS software version 19 (P≤0.05). Results: The results showed that calcium and vitamin D supplementation and resistance training significantly affected PTH (P = 0.004) and ALP (P = 0.02) levels. Also, it was shown that the ALP response started in the second week (P = 0.001), while the PTH response started in the third week (P = 0.001). Conclusions: According to the findings of the present study, it can be said that in postmenopausal women, the threshold for the response of ALP to resistance training and calcium and vitamin D intake is the second week and the threshold for the response to PTH is the third week.
Examining Regional Research And Development Indicators for the Visegrad Countries
Authors: Namazov Ramil , Bassabi Rashidatu
Published: June 2022

The focus of the study is on the NUTS II regions in the Czech Republic, Slovakia, Hungary, and Poland. The objective is to analyze research and development expenditures, R&D personnel, employment in high technology sectors and labor force with tertiary education and employed in science and technology at NUTS II level. The use of trend analysis to observe the movement and the changes in performance over time for these variables from 2008 to 2020 is done to draw conclusions. Aside the regions around the capitals like Bratislavský kraj in Slovakia, for the Czech Republic at the least, seven of the eight regions rank in the top performers for the variables considered using the criteria determined in the methodology. Similar trends are observed in Hungary and Poland. Also, although Poland has the most number of NUTS II regions, the total number of regions that make it to the top performers compared to the other countries is low. Attention will need to put into these regions lagging behind to allow for a catching up with the other top performers. For instance, the Czech Republic had seven out of eight, and Slovakia had two to three out of the total for most variables. One of the key points in this study is to compare not only the main regions but also other non-capital regions and to show how interested countries are in regional development by observing changes over time.
Finanční nástroje a jejich pákový efekt při naplňování cílů kohezní politiky
Authors: Kraft Jiří , Kraftová Ivana
Published: June 2022

The aim of this paper is to assess the position of EU member countries in the 2014-2020 programming period in terms of the use of financial instruments and to estimate the leverage effect in order to determine the degree of significance of this option for mobilising additional financial resources to fulfil cohesion policy objectives. To achieve the research objective, measures of variability and calculation of the force of financial leverage using available data are used. The results show that the variability of both the contribution to financial instruments from the ESIF and the variability of the average contribution per financial instrument are relatively high for EU member countries. The estimation of the force of financial leverage is simplified with respect to the available data, but at the same time raises legitimate questions as well as data availability requirements for further research evaluations in terms of data transparency.
Odolnost českého venkova v kontextu trendů digitální propasti mezi městy a venkovem v rozvojových dokumentech české vlády a Evropské unie
Authors: Wokoun René , Ledvinová Petra
Published: June 2022

The issue of rural resilience is a traditional research topic, but in the last ten to twenty years this question has arisen as a result of the relatively rapid development of society's digitalisation in a new way, ie rural resilience in the context of urban and rural digital divide trends. In our paper, we focus on the issue of the resilience of the Czech countryside in the context of trends in the digital divide between urban and rural areas in the development documents of the Czech government and in the broader context of European Union documents. The aim of the article is to clearly state the main moments from important Czech and EU documents related to the main topic. The main method is excerpting the available documents and synthesis of the acquired knowledge. We also dealt with the importance of high-speed internet and digital abyss between cities and rural areas as well as on an example of primary schools. The main results are the finding that all Czech documents and EU strategies focus generally on high-speed internet and network development and pay only limited attention to rural regions. In connection with our topic, it is interesting to note that the key EU documents show the priority of ICT as an important means of fulfilling the objectives of the priority axes, including rural regions. However, the development of digitization is significant in urban regions, and in rural areas we are witnessing rather lagging behind, which is only to a limited extent reflected in the documents.
Local Development Actors Classification in the Context of the Slovak Least Developed District Policy
Authors: Varecha Lukáš , Melichová Katarína
Published: June 2022

At the end of 2015, a policy of support for the least developed districts was introduced in the conditions of the Slovak Republic. It was conceived as a place-based policy with an emphasis on the involvement of local actors in the processes of its preparation and implementation in the districts. The aim of the paper is to categorize local actors involved in LDD policy on the basis of their attitudes towards selected aspects of the preparation and implementation of LDD policy Action plans in the districts. The local development actors were classified into four clusters, reflecting the polarization of actors to "those whose needs have been met" and critics of LDD policy processes. The attitudes identified in the clusters are mostly not linked to the sectoral affiliation nor the district in which the actor was located. However, they are linked to the status of the actor as a member of the Development board - they are strongly represented in two specific clusters: Satisfied actors and Critics of central level institutions. Most actors have been classified as critics of various aspects of the LDD policy. Specifically, those are overall critics of the LDD policy, critics of the policy reform and critics of the central government level.

Published: June 2022

Business and university cooperation, and in particular research cooperation, is one of the key factors for the development of innovation and subsequent economic growth. However, despite the positive benefits, cooperation in some countries, such as the Slovak Republic, is not very significant. The importance of cooperation is growing in regions where a critical mass of innovative enterprises is lacking. The aim of this article is to analyze the current state of cooperation between manufacturing companies and universities in less developed regions of the Slovak Republic. We examined this through a questionnaire survey conducted among manufacturing companies. The results show that universities are one of the least used sources of information for innovation for companies, and the overall low level of cooperation with them compared to other countries corresponds to this. Large companies and companies producing more complex products cooperate significantly more. At the same time, we did not find differences between domestic and foreign companies, nor are there any statistically significant differences between companies from different regions.

Also thanks to pandemic, the sharing economy has recently gained more and more space. The use of the digital platforms that are part of it are present in various market segments. The aim of the article is to find out the involvement of business entities operating in catering and accommodation services in the sharing economy on the basis of a questionnaire survey. At the same time, we tried to identify the positive and negative aspects of the sharing economy from the perspective of individual business entities. We also evaluated the view of these business entities on the use of Internet portal services (eg Bolt food, Wolt, Bistro, Booking, Trivago, etc.) during the pandemic period. The research, which took place in the time period January - February 2022, involved 85 business entities operating in catering and accommodation services from regional cities in Slovakia. The questionnaire survey showed that accommodation and catering facilities in regional cities perceive more positives of the sharing economy than negatives. Of the positives, they perceived the increase in ordes the most, the biggest negative was the increase in competition. The vast majority of businesses have been helped by Internet portals to mitigate the negative effects during the Covid - 19 pandemic.

Published: June 2022

The transport sector is one of the largest sources of greenhouse gas emissions, making a significant contribution to climate change. As the tourism sector is linked to movement in space and the choice of transport mode, it is also affected by the issue of sustainability. The paper aims to evaluate what factors influence the choice of sustainable transport mode on the way to the destination and determine the importance of environmental attitudes of tourism participants in their decision-making process. Similarly, the connection between sustainable behaviour in the home environment and the willingness to pay extra for a greener transport mode is investigated. A questionnaire was compiled based on relevant scientific literature. It was distributed electronically in the period October–November 2021, primarily among respondents in the age group of 18–35 years, which is widely discussed in the scientific literature. In a sample of 255 respondents, respondents with a greener mindset gave higher importance to the environmental impact of the transport mode and were willing to pay more for greener mode. Although the plane was one of the most widely used modes, there was a larger proportion in a more sustainable mode of transport among more environmentally friendly respondents.

Published: June 2022

One of the specifics of overtourism is its uneven distribution in space and time. Defining an area where the manifestations are visible and the people living in the area are affected is important not only for the correct interpretation of objective numerical indicators, which are used to identify a potential problem, but especially for the application of appropriate measures to alleviate overtourism. The aim of this article is to define, based on direct knowledge of selected destinations in Karlštejn and Kladruby nad Labem, the behavior of visitors in the destination and map materials, the relevant tourist area for the study of overtourism, its impacts and manifestations. In this process, a demand-oriented approach is used. The area is defined both graphically in ArcMAP ESRI and numerically with the function Dissolve. In connection with the visual and numerical delimitation of the area, selected indicators of tourism pressure for both mentioned destinations are calculated. The values compared to corresponding values in other destinations suffering from overtourism indicate the presence of overtourism in Karlštejn.

Published: June 2022

The Nitra Region has favorable natural conditions for growing vines. Of the total number of 354 municipalities in the region are 271 of them wine-growing. There are 18 wine-growing districts on its territory, which are part of 3 wine-growing regions. The Nitra wine-growing region (178) has the most wine-growing municipalities, ahead of the South Slovakian (77) and Central Slovakian (16) region. Among the districts, the highest number is in the Zlatomoravecký (31), Vrábeľský (26) and Nitriansky (23) wine-growing districts, which are part of the Nitra wine-growing region. The Nitra Region has 234 registered winemakers, which represents more than 31% of registered winemakers in Slovakia. Natural persons (117) predominate over limited liability companies (94) and cooperatives (14). According to the number of registered winemakers, Nové Zámky (71), Komárno (55) and Levice (53) districts are leading. Of the wine-growing districts, Hurbanovský (45), Strekovský (32) and Tekovský (29) are significant. The aim of the paper was to present the structure of wine entities in the Nitra Region on the basis of legal form at various regional levels. We also focused on the basic characteristics of wine-growing areas in the region. We used several methods in processing the monitored issues. The main method used was the method of analysis. We also used a comparative method and statistical-mathematical methods. We expressed the obtained data graphically and cartographically using cartographic methods.
Pracovná integrácia v slovenskom poľnohospodárstve

The concept of social agriculture is based on the use of the benefits of productive and non-productive functions of agriculture to support the quality of life of socially or medically disadvantaged people. In connection with the benefits, emphasis is placed on work integration, social services, rehabilitation, therapy and educational activities, which are provided on the farm premises. The aim of the paper is to examine the possibilities of job integration of disadvantaged job seekers in the agricultural sector in the regions of Slovakia. Specifically, it aims to identify the potential of disadvantaged groups of jobseekers, analyze the capacity of farms in terms of jobs and the importance of agriculture for the regional economy and assess the readiness of farms to employ different groups of disadvantaged jobseekers. Secondary data and a questionnaire survey designed for agricultural enterprises were used in the study.The results of the survey showed that disadvantaged jobseekers account for a significant share of the total number of jobseekers. In the structure of disadvantaged jobseekers, long-term unemployed job seekers and job seekers over the age of 50 predominate in all regions. The questionnaire survey confirmed that these groups of disadvantaged job seekers are also the largest group that farms employ or plan to employ in the future. The absorption capacity of agricultural holdings can be limiting. Job capacity and the concentration of the agricultural sector indicate the spatial potential for the application of the concept of social agriculture. The paper also focuses in more detail on selected disadvantaged groups in the labour market, whose integration in the market may require a greater degree of adaptation of conditions by the employer.
Sú znalostne-intenzívne podniky naozaj inovatívne a náročné na znalosti?
Authors: Hrivnák Michal , Moritz Peter
Published: June 2022

Today, knowledge-intensive entrepreneurship is not only a scientifically researched but also practically used concept of entrepreneurship in sectors that have an increased demand for new knowledge and technologies. However, we still consider the low level of examination of the real innovation potential of companies from such classified sectors to be a gap in knowledge. The purpose of the empirical study is to examine the extent to which knowledge-intensive entrepreneurship in the category of small and medium-sized enterprises really contributes to the innovation performance of the economy, and whether their definition is based on relevant criteria. The conclusions point to a certain degree of practical fuzziness of the concept of knowledge-intensive entrepreneurship, if it is based predominantly on the definition of knowledge-intensive activities based on the criterion of employing an increased share of employees with a university degree. Using the results of the Monitor of Innovation Activities of Knowledge-Intensive Activities in Small and Medium-sized Enterprises, we did not prove the relationship between the innovation performance of knowledge-intensive SMEs and the volume of educated human capital in enterprises.

Mathematical and statistical modeling of hierarсhy and heterarchy of economic-geographical systems
Authors: Cherkashin A.K. , Myadzelets A.V.
Published: June 2022

The paper considers the structure of territorial economic-geographical system of Russian regions in the vertical (hierarchy) and horizontal (heterarchy) aspects using methods of mathematical modeling of a multilevel indicative function. It connects indicators of socio-economic development of regions and takes into account characteristics of the economic-geographical environment and regional spatial hierarchy. For the model calculations, we use data of dependence of the annual regional domestic in- vestment on the volume of industrial and agricultural production from 1999 to 2018. The calculated values of investment acceleration indicators vary in time and between regions. They reflect the variability of the economic-geographical environment at the different hierarchical levels. A logical chain of regression equations statistically describes the vertical hierarchy of the Russian economic system. Linear regional trends form groups, or congruencies, with similar norms of the socio-economic environment at the federal okrug level. The congruencies shape the all-Russian directive surface, or directress, and demonstrate diversity of the levels and directions of region development. Described in terms of the relationship between domestic investment and production volumes, the structure reflects the hierarchy of the Russian economic system at the regional, okrug and state levels and forms spatial heterarchical network of similarity of economic growth potentials.

Background: Higher levels of thyroid autoantibodies in follicular fluid (FF) of thyroid autoimmunity (TAI) positive women are strongly correlated with serum levels and may have effect on the post-implantation embryo development. Literature highlights that levothyroxine (LT4) treatment may attenuate the risk of adverse pregnancy outcomes. The aim of the study was to estimate the pregnancy and newborn outcomes in women with FF thyroid autoantibodies undergoing assisted reproductive technology (A RT). Methods: The study population included 24 women with confirmed clinical pregnancy, 8 TAI positive and 16 TAI negative women. LT4 supplementation was applied in 20.8% patients, TAI positive. Results: Pregnancy outcomes were: twin pregnancy rate 4 1 .7 % , early miscarriage rate 8.3% , late miscarriage rate 4.2% , preterm birth rate 16.7% , term birth rate 70.8% , live birth rate 96.0% . There was significant difference in serum and in FF TgAbs (p< 0.001)betw een the groups according to TAI, while serum fT 3 was lower in the group with TAI (p = 0 .0 4 7 ). Serum P 4 was higher in LT4 treated group (p = 0 .0 0 5 ), with TAI, and newborns in this group had higher birth weight (p = 0.001) and height (p = 0 .0 0 8 ). Maternal complications occurred in 23.8% of patients. No congenital malformations in newborns were noted. Conclusions: Thyroid autoantibodies present in FF may have an effect on the post-implantation embryo development, but have no effect on further course of pregnancy. The special benefit of LT4 treatment for successful A R T outcome was demonstrated for newborn anthropometric parameters.
Creencias del futuro profesorado: multilingüismo y la enseñanza de lenguas
Authors: Gartziarena Mikel , Altuna Jon
Published: June 2022

En las últimas décadas, los pilares de la escuela multilingüe se han afianzado en la Unión Europea, plasmándose en infinidad de propuestas metodológicas innovadoras y en iniciativas precursoras a nivel mundial para la recuperación y transmisión de lenguas minoritarias. En este sentido, el diseño curricular en el País Vasco y Navarra orbita en torno a tres lenguas: el euskera, el español y el inglés. La aportación del presente estudio consiste, por un lado, en explorar y describir las características más destacables de las creencias del futuro profesorado (estudiantes del grado de educación primaria e infantil) sobre su perspectiva hacia el multilingüismo y las metodologías de enseñanza de lenguas modernas y, por otro, medir la influencia de dos factores en el desarrollo de dichas creencias: uno, el prácticum y, dos, el año académico. Para ello, se plantea un enfoque cuantitativo y, mediante un cuestionario online, se recogen las creencias de 564 estudiantes de los grados de educación. Se realizaron análisis descriptivos y de varianza (ANOVA), para explorar las creencias y compararlas entre grupos para determinar su significancia. Los resultados muestran que el futuro profesorado posee un sistema de creencias sobre metodologías de enseñanza de lenguas actualizado y enmarcado en las teorías y corrientes modernas del multilingüismo. Concretamente, las creencias del futuro profesorado parecen estar estrechamente relacionadas con las características de las metodologías comunicativas, reflejando predisposición por la habilidad oral, y la comunicación sobre la corrección de la lengua. Además, el prácticum y el año académico demuestran ser variables significativas en el desarrollo de creencias sobre metodologías más modernas y afines con las teorías actualizadas sobre el multilingüismo. Por ello, la creación e implementación de asignaturas específicas sobre la aplicación de enfoques multilingües en la enseñanza de lenguas en los grados de educación impulsaría un aprendizaje de lenguas más eficaz en el futuro.
Adolescents’ reasoning to manage fake news

Published: June 2022

This study draws on literature on argumentation and critical thinking. Its main goal is to analyse teenagers’ critical thinking to manage scientific information in social networks. We analysed 95 ninth graders’ quality of argumentation on their degree of agreement and their degree of credibility of a fake news item. The design included a dependent variable (argumentative competence), two independent variables (degree of agreement, degree of credibility) and a covariate (reading comprehension). A significant correlation was found between the degree of agreement and the degree of credibility. In addition, the degree of credibility decreases significantly as reading comprehension increases. Students who positioned themselves against the claim of the fake news and those who did not believe it showed higher argumentative quality in their texts than those who both agreed with and believed it. These results bring evidence of the confirmation bias claim when we apply it to fake news. We tend to accept information that confirms our prior beliefs uncritically. Similarly, 83% of those who did not believe the content of the news would consult an additional text, compared to 62.5% of those who agreed with it. This is a result that highlights the urgency of implementing educational guidelines to help students develop critical skills to manage fake news.
Escuela y familias de origen extranjero. Canales y barreras a la comunicación en la educación primaria
Authors: Garreta-Bochaca Jordi , Llevot-Calvet Núria
Published: June 2022

La comunicación entre familias y profesionales es una temática relevante en la relación familia-escuela y en la que se puede seguir profundizando para conocer mejor sus dinámicas, fortalezas y limitaciones. Estudios previos indican que es un tema importante para desarrollar la democratización de los centros escolares y la implicación de las familias, así como mejorar la satisfacción que tienen estas últimas respecto el centro escolar. Además de que influye positivamente en el profesorado y en el alumnado. Desde este planteamiento de que una comunicación fluida y bidireccional es positiva, se diseñó y realizó un estudio con perspectiva cuantitativa. Concretamente, una encuesta telefónica para la que se diseñó un cuestionario y un trabajo empírico que permitió la obtención de una muestra (n) de 1730 representantes de equipos directivos de centros escolares de educación primaria españoles. La muestra fue seleccionada con una distribución proporcional a la población (N) de centros escolares existentes en cada provincia española y el trabajo empírico se realizó durante el curso escolar 2019-2020. La encuesta se ha centrado en conocer los canales de comunicación usados, especialmente con las familias de origen extranjero, y las barreras existentes para que esta sea mejor. Las conclusiones apuntan al uso de múltiples canales de comunicación y que respecto a las familias de origen extranjero adquieren relevancia los canales de comunicación de apoyo. De los resultados los autores concluyen la necesidad de que las escuelas tengan planes o estrategias de comunicación adaptados al perfil de sus familias y que superen la fase de uso de canales de apoyo para potenciar acciones comunicativas más ricas con las familias de origen extranjero.
Research on Lean Shipbuilding and Its Manufacturing Execution System
Authors: Song Tingxin , Zhou Jincheng
Published: June 2022

Based on the work breakdown structure theory, the lean shipbuilding method guided by intermediate products is proposed in this article. The hull segment task package is divided according to the content of the shipbuilding operation. Considering the constraints of resources and personnel at the production site, the scheduling strategy of the task package is formulated. Moreover, a virtual flow production system of the shipbuilding workshop is established. On this basis, a lean shipbuilding manufacturing execution system for small and medium-sized shipbuilding enterprises is developed to achieve lean production in a shipbuilding workshop. The application results indicate that implementation of the lean shipbuilding method and manufacturing execution system can significantly reduce the ship production cycle and the number of operators, as well as improve the production efficiency.

Introduction

In recent years, to resist strong international competition, manufacturers are under great pressure to develop products more efficiently and economically (Nam et al. 2016). The ship manufacturing industry, which faces fierce market competition, helps many nations’ economic systems (Rahman & Karim 2015). For example, the shipbuilding industry contributed over $37 billion of the Gross Domestic Product (GDP) to the U.S. economy in 2013 (MARAD 2015). Currently, China’s shipbuilding industry is in a downturn. If the shipbuilding enterprises want to survive and improve their competitiveness, they must reduce labor costs and shorten the production cycle. Lean production is a type of management philosophy born in Toyota Motors. One of the lean thinking goals is to eliminate waste, which can increase work satisfaction and turn waste into value. It should be emphasized that lean thinking must go beyond the company. In other words, lean thinking has to be employed from the product design to the set of activities delivered to the end customer (Barbosa 2014). Lean manufacturing technology focuses on eliminating all types of waste in the manufacturing process and reducing the lead time (Zhu et al. 2019).

Purpose: Survivors of childhood leukemia are at risk of growth impairment due to intensive chemotherapy and radiation treatments. This study investigated the auxological and biochemical characteristics of childhood leukemia survivors diagnosed with growth hormone deficiency (GHD) and the changes in these parameters after 1 year of growth hormone (GH) treatment.Methods: A total of 24 children diagnosed with GHD after leukemia treatment was analyzed. Clinical and biochemical data were collected retrospectively at leukemia diagnosis, GHD diagnosis, and 1 year after GH treatment. Standard deviation score (SDS) was calculated based on the age- and gender-adjusted population.Results: Of the 24 children included in this study, 19 received GH treatment. The median age at GHD diagnosis was 12.3 years, and the median delay in bone age was 1.46 years. Height SDS decreased from -0.69 at leukemia diagnosis to -2.58 at GHD diagnosis (P<0.001). The change in height SDS with and without GH for 1 year was 0.35 and -0.21, respectively (P=0.044). In regression analyses, higher height SDS at GHD diagnosis and a smaller decrease of the height SDS between leukemia and GHD diagnoses were positively correlated with height SDS after GH treatment.Conclusion: GH treatment could be beneficial and safe for improving height in childhood leukemia survivors with GHD. Height SDS at GHD diagnosis and reduction of height SDS between leukemia and GHD diagnosis could be potential factors in predicting the therapeutic effects. Close auxological monitoring is recommended for any childhood leukemia survivors who experience posttreatment height decline.

Hypothalamic hamartomas (HHs) are nonneoplastic mass lesions located in the hypothalamus that can cause central precocious puberty (CPP) and/or gelastic seizures. Seckel syndrome 5 (OMIM210600, SCKL5) is a rare autosomal recessive genetic spectrum disorder characterized by intrauterine growth retardation, proportionate osteodysplastic primordial dwarfism, a wide range of intellectual disability, "bird-headed" facial features, and microcephaly with various structural brain abnormalities. Two siblings presented with short stature and small head circumference and were diagnosed with SCKL 5. The younger sister had HH with CPP and experienced a slipped capital femoral epiphysis during treatment. The 2 siblings had the same genetic variant but showed different phenotypes, which has not been reported previously; this study also as presents the first cases of SCKL5 diagnosed by genetic confirmation in Korea.

The present work aims to explore the knowledge that the students of the Master’s Degree in Teaching at the University of La Laguna have about the functions of educational guidance and their role as teachers and tutors. To this end, this paper presents a review of the role of educational guidance in a Secondary Education center and the role of the tutor. Teachers’ perception of the educational guidance and tutorial function, its importance and difficulties, and the evolution of initial training until reaching the current Master's degree is also presented. In addition, a mixed methodology is used, focused on a documentary analysis of the Title Verification and the teaching guides, a focus group interview, and a questionnaire on the self-perception of students of the competences in tutoring and educational guidance. The results show that students consider that the Master’s program does not include sufficient training with respect to their tutoring and mentoring functions. Finally, the conclusion is reached that the students do not consider themselves prepared to exercise the tutorial function and proposals are suggested to improve this training.
Aralıksız psödobulber ağlama atakları ile başvuran geç juvenil başlangıçlı bir metakromatik lökodistrofi olgusu
Authors: BOLAYIR Aslı
Published: June 2022

Giriş: Metakromatik lökodistrofi (MLD), Arilsülfataz A(ASA) enzimini kodlayan ASA geninde meydana gelen otozomal resesif mutasyon sonucu ortaya çıkan nadir ve kalıtımsal lizozomal bir hastalıktır. Hastalık, başlangıç yaşına göre geç infantil, juvenil ve yetişkin tip olmak üzere 3 gruba ayrılır.

Olgu: 20 yaşında kadın hasta iki gün önce başlayan ve aralıksız devam eden ağlama nedeniyle başvurdu. Hastanın ikili antiepileptik ilaç kullanımı gerektiren on yıllık jeneralize nöbet öyküsü de mevcuttu. Nörolojik muayenede yaygın spastiste, artmış derin tendon refleksleri ve ekstansör taban derisi yanıtları saptandı. Elektroensefalografide epileptik aktivite olmaksızın paroksismal kortikal yavaşlama izlendi. Sistemik muayenede ve laboratuvar tetkiklerinde belirgin özellik yoktu. Beyin manyetik rezonans görüntülemede (MRG), MLD tanısını destekleyen anormal bulgular tespit edildi. Referans bir laboratuvarda periferal kan lökositlerindeki ASA aktivitesi düşük saptandı. Yapılan genetik inceleme PSAP geninde heterozigot bileşik I179S mutasyonu olduğunu ortaya koydu. Hasta ketiapin tedavisi altında kısmi iyileşme taburcu edildi.

Tartışma ve Sonuç: MLD, ASA enzim aktivitesindeki defisitin neden olduğu progresif seyirli nadir kalıtımsal bir hastalıktır. Hastalık ilerledikçe kaçınılmaz olarak çeşitli nörolojik sekeller gelişir. MRG’de jeneralize kortikal atrofi ile periventriküler beyaz cevherde simetrik yaygın hiperintens sinyal değişiklikleri, ASA aktivitesinde azalma ve PSAP genindeki mutasyon tanıyı doğrular. Sonuç olarak biz, MRG’deki MLD'ye ait değişikliklerin neden olmuş olabileceği aralıksız devam eden psödobulber ağlama ile prezente olan bir MLD olgusu sunuyoruz.

Diplazium esculentum is one of the medicinal plants used by Dayak tribes in Central Kalimantan to cure acne. The potential of D. esculentum can be proved through information on the active compounds of the extract obtained in decoction and infusa methods. Thus, a liquid chromatography-mass spectrophotometry (LC-MS)-based method is developed to identify the active compounds of D. esculentum extract in either decoction method or infusa method. The chemical compound potential of D. esculentum extract was then analysed using bioinformatics approach based upon the database of PASS online server. Results showed that the D. esculentum extract contained 81 chemical compounds in decoction method and 68 compounds in infusa method, in which the dominant compound was flavonoid. Moreover, PASS online web server analysis found 7 flavonoid compound groups potential as anti-acne containing antisebor, AR expression inhibitor and CYP1A1 inhibitor. This information could be very useful for designing a clinical test on plant natural compound potential for traditional drug development
