Published: February 2020

The purpose of the study was to analyze the effect of surface sediment characteristics including texture, organic carbon content, and redox potential of sediments on the distribution and accumulation of heavy metals Pb and Zn in three different water zones of each river, estuary and coast. Sediment texture was determined by pipette method, organic carbon content in sediments using Walkley and Black method, redox potential of sediments measured by Eh Meter, and concentrations of heavy metals Pb and Zn in sediments with Atomic Absorption Spectrophotometer with graphite furnace system. The results showed that the distribution and accumulation pattern of heavy metals Pb was similar to Zn where the highest concentration was in the coastal waters zone and the lowest was in the estuary waters zone. Sediment texture in the three zones of the dominant was sand. The percentage of organic carbon content in sediments ranges from 1.63-3.25% and the sediment redox potential was classified as reduction and transition zones. The parameters of texture, organic carbon content, and sediment redox potential have a significant influence on the distribution and accumulation of heavy metals Pb and Zn in sediments in all three water zones. Tujuan penelitian adalah menganalisis pengaruh karakteristik sedimen permukaan meliputi tekstur, kandungan karbon organik, dan potensial redoks sedimen terhadap distribusi dan akumulasi logam berat Pb dan Zn di tiga zona perairan berbeda masing-masing sungai, estuaria, dan pantai.

The coral reef was a habitat for several groups of biota that live in this ecosystem. Some species or group species of benthic fauna are known to be ecologically important and others are economically important so that they can be used as indicators to assess reef health. Research on megabenthic fauna in Ternate and its surrounding waters, North Maluku, was carried out in 2012, 2015, 2016, 2017 and 2018 at fourteen permanent stations. The purpose of this study was to determine the fluctuations in several megabenthic faunae temporarily. Data were collected using the modified Belt Transect Method, namely Benthos Belt Transek method. Eight species or groups of megabenthic fauna in the coral reef have been observed. The highest distribution and abundance of megabenthic fauna was coral polyps eating-snail of Drupella spp. The species wealth index decreased from 2012 to 2017 (1.17 to 1.05) but experienced an increase in 2018 (to 1.29). The relatively high dominance found in the megabenthic fauna community was observed in 2015, 2016 and 2017, while in 2012 and 2018 it had relatively low dominance. The megabenthic fauna community observed in 2012 and 2018 has relatively high diversity, whereas in 2015, 2016 and 2017, the diversity is relatively low. The megabenthic fauna community observed in 2012 and 2018 has spread evenly, while in 2015, 2016 and 2017, the relative prevalence of fauna is relatively uneven.  Terumbu karang merupakan habitat bagi beberapa kelompok biota yang hidup di dalamnya.

Published: February 2020

Awareness of Mud Crab over exploitation in Mangkang Wetan Waters has been noticed. One of the reference information is the growth study to determine the condition of the mud crab population. High demand encourages the fisherman to catch more, which leads to overexploitation in nature. The study aimed to estimate the growth, mortality, and exploitation rate of mud crabs. The 921 mud crabs samples were collected from Mangkang Wetan Waters from October 2018 to January 2019. The method used was the survey method. The crabs were taken once a week for 4 months. The width and weight of crab carapace were measured. The growth rate of S. serrata was 0.93/year (male) and 0.69/year (female). The natural mortality rate of S. serrata was 1.08/year (male) and 0.89/year (female), the mortality of catch (F) was 0.55/year (male) and 1.09/year (female). The rate of exploitation of male S. serrata reached 34%, and the rate of exploitation of female S. serrata was 55%. The exploitation of female S. serrata shows that overexploitation has occurred because the optimum value of exploitation (E-OPTIMUM) is equivalent to E=50%.
On the Equilibrium Uniqueness in Cournot Competition with Demand Uncertainty
Authors: Leonardos Stefanos , Melolidakis Costis
Published: February 2020

We revisit the linear Cournot model with uncertain demand that is studied in Lagerlöf (2006. “Equilibrium Uniqueness in a Cournot Model with Demand Uncertainty.” The B.E. Journal of Theoretical Economics 6, no. 1. (Topics), Article 19: 1–6.) and provide sufficient conditions for equilibrium uniqueness that complement the existing results. We show that if the distribution of the demand intercept has the decreasing mean residual demand (DMRD) or the increasing generalized failure rate (IGFR) property, then uniqueness of equilibrium is guaranteed. The DMRD condition implies log-concavity of the expected profits per unit of output without additional assumptions on the existence or the shape of the density of the demand intercept and, hence, answers in the affirmative the conjecture of Lagerlöf (2006. “Equilibrium Uniqueness in a Cournot Model with Demand Uncertainty.” The B.E. Journal of Theoretical Economics 6, no. 1. (Topics), Article 19: 1–6.) that such conditions may not be necessary.
F2S3: Robustified determination of 3D displacement vector fields using deep learning
Authors: Gojcic Zan , Zhou Caifa , Wieser Andreas
Published: February 2020

Areal deformation monitoring based on point clouds can be a very valuable alternative to the established point-based monitoring techniques, especially for deformation monitoring of natural scenes. However, established deformation analysis approaches for point clouds do not necessarily expose the true 3D changes, because the correspondence between points is typically established naïvely. Recently, approaches to establish the correspondences in the feature space by using local feature descriptors that analyze the geometric peculiarities in the neighborhood of the interest points were proposed. However, the resulting correspondences are noisy and contain a large number of outliers. This impairs the direct applicability of these approaches for deformation monitoring. In this work, we propose Feature to Feature Supervoxel-based Spatial Smoothing (F2S3), a new deformation analysis method for point cloud data. In F2S3 we extend the recently proposed feature-based algorithms with a neural network based outlier detection, capable of classifying the putative pointwise correspondences into inliers and outliers based on the local context extracted from the supervoxels. We demonstrate the proposed method on two data sets, including a real case data set of a landslide located in the Swiss Alps. We show that while the traditional approaches, in this case, greatly underestimate the magnitude of the displacements, our method can correctly estimate the true 3D displacement vectors.
Performance of Moving Average (MA) Chart Under Three Delta Control Limits and Six Delta Initiatives
Authors: Kalpesh S Tailor
Published: February 2020

An SQC chart is a graphical tool for representation of the data for knowing the extent of variations from the expected standard. This technique was first suggested by W.A. Shewhart of Bell Telephone Company based on 3σ limits. M. Harry, the engineer of Motorola has introduced the concept of six sigma in 1980. In 6σ limits, it is presumed to attain 3.4 or less number of defects per million of opportunities. Naik V.D and Desai J.M proposed an alternative of normal distribution, which is named as moderate distribution. The parameters of this distribution are mean and mean deviation. Naik V.D and Tailor K.S. have suggested the concept of 3-delta control limits and developed various control charts based on this distribution. Using these concepts, control limits based on 6-delta is suggested in this paper. Also the moving average chart is studied by using 6-delta methodology. A ready available table for mean deviation is prepared for the quality control experts for taking fast actions.

In the current manuscript, we have demonstrated the recent generalization of Weibull-G exponential distribution (three-parameter) and it is a very familiar distribution as compared to other distribution.It has been found that Weibull-G exponential distribution (WGED) can be utilized pretty efficiently to evaluate the biological data in the position of gamma and log-normal Weibull distributions. It has two shape parameters and the three scale parameters namely, a, b, λ. Some of its statistical properties are acquired, which includes reserved hazard function, probability-density function, hazard-rate function and survival function. Our aim is to shore-up the results of life-time using three-parameter Weibull generalized exponential distribution. Hence, the corresponding probability functions, hazard-rate function, survival function as well as reserved hazard-rate function has been analyzed in the 3 weeks of high-intensity exercise training in short-term. The outcomes of the present study supporting the results of life-time data that the interim elevated intensity exercise activity attenuated an acute exercise induced growth hormone release.

Authors: Banajit Sarmah  , Anuradha Devi  , Jnanjyoti Sarma
Published: February 2020

A fluid model is considered to study the nonlinear dust- acoustic waves (DAW) in magnetized dusty plasma. The model consists of dust articles having negative charge, nonthermal ions, and Boltzmann electrons. Sagdeev Potential equation is derived in the form of an energy integral by applying nonperturbative approach. The pseudopotential (Sagdeev potential) profile is analyzed to study the characteristic of the solitary waves. The study has been made related to the transition of the DAW and the corresponding characters by observing the variation of amplitudes and width of the solitons with Mach number, temperature ratio, density ratio, concentration of nonthermal ions, and the direction cosine. The parametric ranges are estimated numerically to confirm the existence of solitary waves of arbitrary amplitude.

Published: February 2020

We reassess two specimens, part of the late Dr Minoru Imajima’s collections, from Japan of the flabelligerid genus Brada Stimpson, 1853. We re-identify the specimens as B. kudenovi Salazar-Vallejo, 2017 and newly record this species from Japan, which represents the southernmost locality of the genus worldwide. The specimens were previously reported as B. inhabilis (Rathke, 1843), which has Molde, Norway as its type locality. However, the morphological features are identical to the original description of B. kudenovi in the following: the body is whitish in alcohol; there are one or two multiarticulate notochaetae per parapodium; the neuropodial lobes are low, not projecting; and the body papillae are short.
Optimization of mobile robot movement on a plane with finite number of repeller sources
Authors: Medvedev Mikhail , Kostjukov Vladimir , Pshikhopov Viacheslav
Published: February 2020

The paper considers the problem of planning a mobile robot movement in a conflict environment, which is characterized by the presence of areas that impede the robot to complete the tasks. The main results of path planning in the conflict environment are considered. Special attention is paid to the approaches based on the risk functions and probabilistic methods. The conflict areas, which are formed by point sources that create in the general case asymmetric fields of a continuous type, are observed. A probabilistic description of such fields is proposed, examples of which are the probability of detection or defeat of a mobile robot. As a field description, the concept of characteristic probability function of the source is introduced; which allows us to optimize the movement of the robot in the conflict environment. The connection between the characteristic probability function of the source and the risk function, which can be used to formulate and solve simplified optimization problems, is demonstrated. The algorithm for mobile robot path planning that ensures the given probability of passing the conflict environment is being developed. An upper bound for the probability of the given environment passing under fixed boundary conditions is obtained. A procedure for optimizing the robot path in the conflict environment is proposed, which is characterized by higher computational efficiency achieved by avoiding the search for an exact optimal solution to a suboptimal one. A procedure is proposed for optimizing the robot path in the conflict environment, which is characterized by higher computational efficiency achieved by avoiding the search for an exact optimal solution to a suboptimal one. The proposed algorithms are implemented in the form of a software simulator for a group of ground-based robots and are studied by numerical simulation methods.
Digital Radio Networks Centralized Elements Synchronization Model with Random Multiple Access to the CSMA/CA Type Medium
Authors: Peregudov Maksim , Steshkovoy Anatoliy
Published: February 2020

Currently, there is a great interest in digital radio network centralized elements synchronization with random multiple access to the CSMA/CA type , the effectiveness of which determines the process of establishing a communication session. At the same time, there was no assessment effectiveness digital radio communication network centralized elements synchronization with random multiple access to the CSMA/CA type. Also, there was no assessment made the contribution of potential destructive actions by the attacker to the reduction in the effectiveness of such synchronization. This paper presents digital radio networks centralized elements synchronization analytical model with random multiple access to the CSMA/CA type medium. In this model the theoretical resulting indicator is the probability of successful delivery of a synchronization package, and a package frequency of successful delivery is used in experimental indicator evaluation . The model takes into account the potential destructive effects of the attacker in analytical expressions for known probabilistic indicators. An digital radio network  centralized elements synchronization with random multiple access to a CSMA/CA type experimental study an environment is also presented. The most common network of digital radio standard IEEE 802.11 (Wi-Fi) is considered as such network. The experimental research results differ from the theoretical research results slightly, which indicates the adequacy of the developed analytical model. It was established, firstly, that the successful delivery probability of a synchronization packet does not depend on number of subscriber terminals in digital radio communication networks, secondly, with an average duration of a data packet transmission by such terminal less than 0.85 ms, it is advisable to use non-random, and the reserved multiple access to the environment, and, thirdly, centralized synchronization is resistant to destructive influences. The model is applicable in the design of digital radio networks with random multiple access to the medium such as CSMA/CA, as well as in optimizing the operation of such networks.
Financial Stability Committees and Basel III Macroprudential Capital Buffers
Authors: Edge Rochelle M. , Liang J. Nellie
Published: February 2020

We evaluate how a country’s governance structure for macroprudential policy affects its implementation of Basel III macroprudential capital buffers. We find that the probabilities of using the countercyclical capital buffer (CCyB) are higher in countries that have financial stability committees (FSCs) with stronger governance mechanisms and fewer agencies, which reduces coordination problems. These higher probabilities are more sensitive to credit growth, consistent with the CCyB being used to mitigate systemic risk. A country’s probability of using the CCyB is even higher when the FSC or ministry of finance has direct authority to set the CCyB, perhaps because setting the CCyB involves establishing a new macro-financial analytical process to regularly assess systemic risks and allows these new entities to influence the process. These results are consistent with elected officials creating the FSCs with the strongest governance and fewer agencies for functional delegation reasons, but most FSCs are created for symbolic political reasons.
Effects of High Sugar Content on Fermentation Dynamics and Some Metabolites of Wine-Related Yeast Species Saccharomyces cerevisiae, S. uvarum and Starmerella bacillaris
Authors: Oláhné Horváth Borbála , Nyitrainé Sárdy Diána , Kellner Nikolett , Magyar Ildikó
Published: February 2020

Starmerella bacillaris (synonym Candida zemplinina) is an important non-Saccharomyces yeast in winemaking with valuable oenological properties, accompanying Saccharomyces species in sweet wine fermentation, and has also been suggested for application as combined starter culture in dry or sweet wines. In this study, the major metabolites and nitrogen utilization of these yeasts are evaluated in the musts with high or extremely high sugar concentration. The change in the metabolic footprint of Saccharomyces cerevisiae, Saccharomyces uvarum and Starmerella bacillaris strains was compared when they were present as pure cultures in chemically defined grape juice medium with 220 and 320 g/L of sugar, to represent a fully matured and an overripe grape. Surprisingly, the extreme sugar concentration did not result in a considerable change in the rate of sugar consumption; only a shift of the sugar consumption curves could be noticed for all species, especially for Starmerella bacillaris. At the extreme sugar concentration, Starmerella bacillaris showed excellent glycerol production, moderate nitrogen demand together with a noticeable proline utilisation. The change in the overall metabolite pattern of Starmerella bacillaris allowed clear discrimination from the change of the Saccharomyces species. In this experiment, the adequacy of this non-Saccharomyces yeast for co-fermentation in juices with high sugar concentration is highlighted. Moreover, the results suggest that Starmerella bacillaris has a more active adaptation mechanism to extremely high sugar concentration.

Pharmacological treatment and inappropriate prescriptions in patients with psoriasis v1
Authors: Fernando Valladales Restrepo Luis , Enrique Machado Alba Jorge
Published: February 2020

Psoriasis is a chronic inflammatory and systemic disease that primarily affects the skin, nails, and joints. Some medications have been linked to worsening clinical manifestations of cutaneous psoriasis. Our objective was to identify pharmacological treatments and drugs related to worsening dermatological lesions in patients with psoriasis. This was a cross-sectional study from a population database that identified the prescriptions of patients with psoriasis during 2019. All medications prescribed for the treatment of psoriasis and other comorbidities were investigated for being potentially inappropriate because they could worsen the problem. We identified 2088 patients with psoriasis, with a mean age of 53.6±15.5 years, and 52.9% were men. A total of 92.6% received pharmacological treatment, and of these, topical corticosteroids were the most commonly used group (76.6%). A total of 55.3% of patients with cutaneous psoriasis received at least one drug associated with worsening dermatological lesions. The most frequent were naproxen (25.5%), diclofenac (14.7%), and dexamethasone (10.8%). Residing in Barranquilla (OR:1.27, 95%CI:1.009-1.607), having any chronic comorbidities (OR:1.94, 95%CI:1.566-2.402), and having a history of coronary heart disease (OR:6.25, 95%CI:1.895-20.645) increased the probability of receiving these prescriptions. The pharmacological treatment of psoriasis was in accordance with the recommendations of the clinical practice guidelines, but the high proportion of potentially inappropriate prescriptions makes it necessary to promote educational and pharmacovigilance strategies that improve the formulation habits of the physicians involved in the treatment of these patients.

The aim of this study was to examine the effect of motivational technique on enhancing students’ English achievement. To bring into effect, quasi- experimental was designed. From the total of six sections, two were randomly taken and signed one as experimental (N=40) and other as controlled group (N=40) by lots so that each sections (intact groups) have equal probability to be selected. The study used document review and test as the main tool of data collection to compare the mean score of both groups before and after the treatment. The reviewed document and test was analyzed by (SPSS 20). The result of the reviewed document (students’ rooster) before training revealed that both groups were almost at the same level of language achievement. However, after teaching with selected motivational techniques, the result of experiential group was significantly different with the control group taught in a conventional classroom (usual classroom teaching). As a result, the alternative hypothesis (H1) was accepted; whereas, the null hypothesis (H0) was rejected. Based on the findings above, employed motivational techniques in EFL classroom enhance students EFL achievement. As a result, teachers should use selected motivational techniques in EFL classroom.

RESUMO: As parasitoses intestinais representam um sério problema de saúde pública. Estão relacionadas com fatores socioeconômicos e ambientais que são responsáveis pela qualidade de vida, condições sanitárias e estado nutricional dos indivíduos de uma população. Enteroparasitoses são doenças fomentadas por helmintos ou protozoários que vivem em uma relação de endoparasitismo, albergando-se no sistema digestório do seu hospedeiro. O Brasil, como um país tropical subdesenvolvido, possui clima e situação socioeconômica favoráveis à ocorrência de doenças parasitárias.  O trabalho teve como objetivo abordar através de uma revisão de integrativa a ocorrência de enteroparasitos em infecções humanas na Região Nordeste. Foi realizado um estudo do tipo descritivo de revisão integrativa, onde foram utilizados como fontes de pesquisa sites de conteúdo científico como PubMed, LILACS, SCIELO e Google acadêmico onde foram utilizadas as palavras chaves “Enteroparasitos”, “Saúde Pública” e “Condições socioeconômicas”, “Região Nordeste”. A pesquisa bibliográfica resultou na obtenção de 601 artigos, dos quais 14 foram selecionados após análise dos critérios de inclusão. O Estado da Paraíba foi o que apresentou o maior número de artigos publicados, seguido pelo estado do Piauí. Já o estado do Rio Grande no Norte não apresentou nenhum artigo publicado durante o período analisado. A metodologia mais utilizada foi a de sedimentação espontânea. Na pesquisa realizada no estado do kkkk houve isolamento de Estrongyloides stercoralis em 2 amostras de fezes, observadas através da utilização do método de Rugai. As espécies Giardia lamblia, Entamoeba coli e Entamoeba histolytica-dispar, foram os protozoários mais citados nos artigos envolvidos na pesquisa. Já entre os helmintos, Ascaris lumbricoides, Enterobius vermiculares e Trichuris trichiuria foram os mais relatados. A alta prevalencia de enteroparasitos indica a falta de políticas públicas efetivas de higiene nas escolas bem como as péssimas condições higienicosanitarias, sócias e ambientais da população estudada.

Sobre el diptongo ortográfico
Authors: Gutiérrez Ordóñez Salvador
Published: February 2020

La Ortografía académica (2010) define las nociones de diptongo e hiato, no con criterios fonéticos, sino con criterios ortográficos. A pesar de las críticas, esta  decisión ha sido una gran aportación teórica y práctica. No solo ha tenido antecedentes, sino que se fundamenta en criterios fonológicos. La frontera morfológica no es relevante en la determinación ortográfica de los diptongos.
Sobre Sexismo lingüístico y visibilidad de la mujer (2012): lecturas imprecisas y tópicos infundados asociados al “Informe Bosque”
Authors: Cabello Pino Manuel
Published: February 2020

Desde su publicación en 2012 el texto “Sexismo lingüístico y visibilidad de la mujer”, más conocido como el “Informe Bosque”, se ha convertido, como es bien sabido, en uno de los más polémicos e influyentes de los últimos años. Pero, en nuestra opinión, se trata también de uno de los que ha sido objeto de las lecturas menos acertadas. En el presente artículo mostraremos cómo las reacciones mayoritariamente tan negativas que propició desde el primer momento entre los partidarios del llamado “lenguaje inclusivo” fueron fruto tanto de su propia lectura apasionada y, por eso mismo, no demasiado precisa del texto, como también de la no menos imprecisa interpretación del texto que realizaron algunos de los supuestos defensores del profesor Bosque. Dichas lecturas erróneas habrían sido motivadas por la pasión con que fue recibido y leído el documentotras más de veinte años de enfrentamiento en estado latente entre partidarios y detractores de ese tipo de lenguaje.
Using Deep Learning to Derive Shear-Wave Velocity Models from Surface-Wave Dispersion Data
Authors: Hu Jing , Qiu Hongrui , Zhang Haijiang , Ben-Zion Yehuda
Published: February 2020

We present a new algorithm for derivations of 1D shear-wave velocity models from surface-wave dispersion data using convolutional neural networks (CNNs). The technique is applied for continental China and the plate boundary region in southern California. Different CNNs are designed for these two regions and are trained using theoretical Rayleigh-wave phase and group velocity images computed from reference 1D VS models. The methodology is tested with 3260 phase–group images for continental China and 4160 phase–group images for southern California. The conversions of these images to velocity profiles take ∼23  s for continental China and ∼30  s for southern California on a personal laptop with the NVIDIA GeForce GTX 1060 core and a memory of 6 GB. The results obtained by the CNNs show high correlation with previous studies using conventional methods. The effectiveness of the CNN technique makes this fast method an important alternative for deriving shear-wave velocity models from large datasets of surface-wave dispersion data.

Background: The present study aimed to compare the clinical efficacy and safety profile of Ziferon and Betaferon.
Objectives: In total, 41 consecutive patients with relapsing forms of Multiple Sclerosis (MS) were selected from the MS outpatient clinic affiliated to Tehran University of Medical Sciences. The patients were randomly assigned into two groups.
Methods: Each group either received Ziferon 250 mcg Subcutaneously (SC) in alternate days or Betaferon 250 mcg SC on alternate days. Clinical and para-clinical outcomes, such as mean relapse rate/year score, mean Expanded Disability Status Scale (EDSS)/year score, the cumulative number, and the volume of gadolinium-enhancing lesions, in addition to the cumulative number of new T2 lesions and safety profile were evaluated for each group during the years of treatment.
Results: There were no significant differences in Magnetic Resonance Imaging (MRI) outcomes (change in total lesion volume, new lesion per T2-weighted scan, and gadoliniumenhancing lesions per T1-weighted scan from baseline; P=0.236, P=0.56, & P=0.496, respectively was observed). There was no significant difference in the relapse rate between Ziferon and Betaferon treated groups (P=0.56). There were no unexpected safety events. The number of patients who discontinued the study due to adverse events occurrence was similar between the two groups.
Conclusion: Evidence demonstrates the non-inferiority and bio-similarity of Ziferon (interferon beta-1b) to Betaferon in terms of efficacy and safety profile.
Cogniciones y Prácticas Parentales en Contexto de Migración
Authors: Gallardo Ana Maria
Published: February 2020

El asentamiento en una sociedad distinta de la propia supone un importante esfuerzo de ajuste y de cambios de costumbres en la vida cotidiana. Una esfera relevante en esta experiencia es el de desafío a la percepción de competencias parentales, puesto que las personas deben abandonar las imágenes normativas asociadas a la parentalidad de su cultura de origen y enfrentarse a nuevas ideas acerca de cómo se debe criar. El proceso descrito previamente ha sido definido como “aculturación parental” y supone un balance entre las cogniciones y prácticas parentales de la cultura de origen en conjunto con las que se adquieren en la cultura receptora. La presente revisión teórica tiene como objetivo profundizar en cogniciones y prácticas parentales en contexto de migración.

Las habilidades socio-emocionales en jóvenes con Trastorno por Déficit de Atención e Hiperactividad (TDAH) son esenciales en su desarrollo psicológico y bienestar personal. No obstante, existen escasos trabajos que muestren la validez de programas de inteligencia emocional en este colectivo. El objetivo del trabajo fue triple: a) la adaptación e implementación de un programa de educación emocional, b) la evaluación de su eficacia y c) el análisis de la satisfacción con el programa de usuarios y familiares. Se utilizó un grupo experimental (n=24) y un grupo control (n=24) de alumnos con TDAH que fueron evaluados en dos momentos temporales. Los resultados evidenciaron que los participantes del programa mejoraban de manera estadísticamente significativa en la dimensión de problemas con los compañeros (SDQ) y en regulación emocional (TMMS-24), si bien no se observaron cambios en autoestima y empatía. Por otra parte, tanto los participantes como sus familiares indicaron una alta satisfacción con la intervención. Los resultados obtenidos indican la necesidad de continuar con el análisis de la eficacia de este programa y se discute la necesidad de potenciar las competencias socio-emocionales en esta etapa que mejoren el bienestar personal, familiar, académico y social de la población infantojuvenil con TDAH.

Malting of barley grains is a procedure known for centuries, however, the technology of malt production is constantly being studied and optimized. The optimizations comprise different conditions of barley steeping, as well as using different additives to improve seed germination. Among the most famous group of seed germination regulators, gibberellins, a broad spectrum of diverse chemical substances also have stimulatory effects on seed germination. This review summarizes what is known about multiple barley seed germination promoting compounds, as well as other chemical/hormonal seed germination regulators described in other plant species. The goal is to provide an impulse for testing new stimulatory substances with potential applications in malting process optimization.

It is well known that, in human communication, physical contact, such as holding hands, has the effect of relieving stress and providing a sense of intimacy. In this study, we verified whether walking hand-in-hand has a positive effect on relationship building between children and robots. Specifically, an interaction experiment was performed in which a child and a robot play one-on-one for approximately 30 min with 37 children aged 5–6 years. The robot is teleoperated by a nursery teacher in this experiment. The children are divided into two groups: the experimental group, in which children walk hand-in-hand during their first encounter with the robot, and the control group, in which children do not have any physical contact with the robot. The change in the interaction is analyzed while taking into consideration the distance between the child and the robot, eye contact rate, and a questionnaire completed by the parents and children. The results reveal that the children in the experimental group interacted significantly with the robot. Moreover, the parents of the children in the experimental group tended to feel that their children appeared to experience intimacy with the robot. These results suggest that walking hand-in-hand has a positive effect on child-robot relationship building.
