Social STEAM Learning at an Early Age with Robotic Platforms: A Case Study in Four Schools in Spain
Authors: Jurado Elena , Fonseca David , Coderch Jorge , Canaleta Xavi
Published: July 2020

Robotics is one of the key learnings in a world where learners will interact with multiple robotic technologies and operating systems throughout their lives. However, school teachers, especially in the elementary and primary education stages, often have difficulties incorporating these tools in the classroom. Four elementary teachers in three schools in Catalonia were trained to introduce robotics in the classroom to seventy-five students. The main actions consisted in classroom accompaniment by a university-trained support teacher, curricular materials’ development, and assessment of the students’ and teachers’ learning. The designed contents and evaluation criteria took into account the potential of educational robotics to improve soft skills and to promote Science, Technology, Engineering, Arts, and Mathematics (STEAM) interdisciplinary learning. Teachers perceived the training to be supportive and useful and ended the school year feeling confident with the used robotic platform (KIBO). The assessment of the students’ learning showed an average mark of 7.1–7.7 over 10 in the final evaluation criteria. Moreover, students’ learning was higher in the classes where the teachers had higher initial interest in the training. We present and analyse the actions carried out, with a critical and constructive look at extending the experience to other educational centers.
Application and Experimental Validation of a Multibody Model with Weakly Coupled Lateral and Vertical Dynamics to a Scaled Railway Vehicle
Authors: Urda Pedro , Muñoz Sergio , Aceituno Javier F. , Escalona José L.
Published: July 2020

In this paper, a multibody dynamic model of a railway vehicle that assumes that vertical and lateral dynamics are weakly coupled, has been experimentally validated using an instrumented scaled vehicle running on a 5-inch-wide experimental track. The proposed linearised model treats the vertical and lateral dynamics of the multibody system almost independently, being coupled exclusively by the suspension forces. Several experiments have been carried out at the scaled railroad facilities at the University of Seville in order to test and validate the simulation model under different working conditions. The scaled vehicle used in the experiments is a bogie instrumented with various sensors that register the accelerations and angular velocities of the vehicle, its forward velocity, its position along the track, and the wheel–rail contact forces in the front wheelset. The obtained results demonstrate how the proposed computational model correctly reproduces the dynamics of the real mechanical system in an efficient computational manner.
Institutional Ambiguity and Ontological Politics in Integrating Sustainability into Finnish Dietary Guidelines
Authors: Santaoja Minna , Jauho Mikko
Published: July 2020

Dietary guidelines are a key policy instrument in guiding the way people eat in many countries. Traditionally, the guidelines focus on the public health aspects of diets. During the last decade, sustainability has increasingly been incorporated into dietary guidelines, emphasizing that sustainable diet benefits both health and the environment. This article analyses the integration of sustainability into dietary guidelines in Finland. The analysis is situated within the ontological turn in social theory, understanding food as ontologically multiple. We employ Annemarie Mol’s concept of ontonorms in analyzing the Finnish dietary guidelines. Currently, in Finland, there seems to be a situation of institutional ambiguity regarding where and by whom sustainable food policy is being made and what does it constitute. We claim that the ontological multiplicity of food is partly constituted by, and at the same time constitutive of, the institutional ambiguity, and as a result, the guidelines do not yet provide clear guidance for sustainable food practices. As the guidelines fail to coordinate the multiplicity, they increase the normative burden on consumers to make responsible choices. In the latest Finnish guidelines targeted for children, however, steps are taken towards a more inclusive, caring understanding of sustainable dietary guidance.

Authors: Liesa-Orús Marta , Latorre-Cosculluela Cecilia , Vázquez-Toledo Sandra , Sierra-Sánchez Verónica
Published: July 2020

To consider that some quality teaching-learning processes in the Higher Education is practically unthinkable without the use of technology, especially because of its impact in developing the necessary skills and abilities for the 21st century. (1) Background: One of the initial steps to successfully approach this challenge is to analyze how university professors consider that ICTs can contribute to developing skills and abilities in their students. In this regard, their perceptions are one of the factors that will limit the use they make of these tools. (2) Method: For this reason, a quantitative research has been designed in which 345 university professors have participated for different branches of knowledge of one Spanish university. (3) Results: Among the most relevant results, we can highlight that the professors recognize the potentials of the ICTs and consider they have a positive effect on learning and development of 21st century skills in their students. These benefits are seen in different fields like communication, collaboration, and critical thinking, among others. Likewise, the importance of the technology culture teaching role is outstanding. (4) Conclusions: Finally, the need for integration of ICTs in a pedagogical model in which professor training in digital skills acquires relevance is shown.

Authors: Zhang Jiazhen , Cenci Jeremy , Becue Vincent , Koutra Sesil , Ioakimidis Christos S.
Published: July 2020

Using the CiteSpace software and bibliometric methods, with the core collection of the Web of Science (WoS) database as the data source, the development of industrial heritage research in China and Western countries since the 2006 Wuxi Proposal was analyzed. The study found that the latest quantitative changes in China and Western countries’ industrial heritage research have similar fluctuations. However, researchers and institutions in the two places are independent of each other, lacking in-depth cooperative research. Notwithstanding, comprehensive and holistic research needs to be strengthened. The research content in China mainly focuses on the issues of urban renewal, industrial heritage tourism and creative industries, whereas Western countries are dominated by heritage and community building industrial heritage, the exploration of tourism and the protection of industrial sites, post-industrial heritage protection, and new technology use. Finally, by comparing and analyzing the research status of the two regions, future research on industrial heritage in China and Western countries are encouraged.
The Moral Competence of Spanish Councilors
Authors: Herrero García Pedro , Carbonero Miguel Ángel , Martín Antón Luis Jorge
Published: July 2020

The citizenship’s distrust of politicians clashes with the absence of research of politicians’ moral competence, which is a challenge to positive psychology. The objective of this work, approved by the Spanish Federation of Municipalities and Provinces, is to measure, for the first time, the moral competence of Spanish councilors and to explore its relationship with different independent variables. A sample of 625 councilors from all the territories of the country completed a questionnaire that includes the Moral Competence Test Moral Competence Test. Estimation parameters and hypothesis contrast methods were used for the statistical analysis of the obtained data. The results indicate that most of the Spanish councilors in the sample have low moral competence, which does not depend on any of the variables contemplated in the study. Councilors with high moral competence represent only 3.7%, with a profile corresponding more closely to that of people under 45 years of age, with university training, professionally linked to the private services sector, and dedicated exclusively to politics in a Town Hall.
Group Analysis of the Boundary Layer Equations in the Models of Polymer Solutions
Authors: Meleshko Sergey V. , Pukhnachev Vladislav V.
Published: July 2020

The famous Toms effect (1948) consists of a substantial increase of the critical Reynolds number when a small amount of soluble polymer is introduced into water. The most noticeable influence of polymer additives is manifested in the boundary layer near solid surfaces. The task includes the ratio of two characteristic length scales, one of which is the Prandtl scale, and the other is defined as the square root of the normalized coefficient of relaxation viscosity (Frolovskaya and Pukhnachev, 2018) and does not depend on the characteristics of the motion. In the limit case, when the ratio of these two scales tends to zero, the equations of the boundary layer are exactly integrated. One of the goals of the present paper is group analysis of the boundary layer equations in two mathematical models of the flow of aqueous polymer solutions: the second grade fluid (Rivlin and Ericksen, 1955) and the Pavlovskii model (1971). The equations of the plane non-stationary boundary layer in the Pavlovskii model are studied in more details. The equations contain an arbitrary function depending on the longitudinal coordinate and time. This function sets the pressure gradient of the external flow. The problem of group classification with respect to this function is analyzed. All functions for which there is an extension of the kernels of admitted Lie groups are found. Among the invariant solutions of the new model of the boundary layer, a special place is taken by the solution of the stationary problem of flow around a rectilinear plate.
New Extensions of Kannan’s and Reich’s Fixed Point Theorems for Multivalued Maps Using Wardowski’s Technique with Application to Integral Equations
Authors: Debnath Pradip , Srivastava Hari Mohan
Published: July 2020

The metric function generalizes the concept of distance between two points and hence includes the symmetric property. The aim of this article is to introduce a new and proper extension of Kannan’s fixed point theorem to the case of multivalued maps using Wardowski’s F-contraction. We show that our result is applicable to a class of mappings where neither the multivalued version of Kannan’s theorem nor that of Wardowski’s can be applied to determine the existence of fixed points. Application of our result to the solution of integral equations has been provided. A multivalued Reich type generalized version of the result is also established.
Overshoot Elimination for Control Systems with Parametric Uncertainty via a PID Controller
Authors: Tsavnin Alexey , Efimov Semen , Zamyatin Sergey
Published: July 2020

One of the key performance requirements for different control systems is non-overshooting step response, so that the controllable value should not overcome the reference value within a transient process. The problem of providing a non-overshooting step response was examined in this paper. Despite much scientific research being dedicated to the overshoot elimination problem, there are little to no results regarding parametric uncertainty for the discussed problem. Consideration of parametric uncertainty, particularly in the form of interval-given parameters, is essential, since in many physical processes, electronic devices and control systems parameter values can be obtained with acceptable error, and they can vary under different conditions. The main result of our research is the development of a proportional-integral-derivative (PID)-controller tuning approach for systems with interval-given parameters that provides a non-overshooting step response for such classes of control systems. This paper investigates analytical conditions and constraints for linear time invariant (LTI) systems in order to have no overshoot, enhances them with respect to parametric uncertainty, and formulates rules for tuning choices of parameters.

Authors: Dassios Ioannis , Bazighifan Omar
Published: July 2020

In this work, new conditions were obtained for the oscillation of solutions of fourth-order non-linear neutral differential equations (NDEs) using the Riccati technique. These oscillation criteria complement and improve those of Chatzarakis et al. (2019). Symmetry plays an important role in determining the right way to study these equation. An example is given to illustrate our theory.

Published: July 2020

Immunotherapy focusing on reducing the amyloid-beta (Aβ) burden is a promising treatment strategy for Alzheimer’s disease (AD). Many clinical studies on AD immunotherapies have failed due to low safety and efficacy, calling for a highly potent AD vaccine which induces sufficient antibody titer while avoiding side effects. Here, we designed a yeast-based vaccine Y-5A15 comprising five copies of Aβ1-15 displayed on the surface of yeast cell wall, and we subcutaneously immunized APP/PS1 mice three times. Our results demonstrated that the Y-5A15 remarkably enhanced the Aβ epitope immunogenicity and elicited high antibody titers against Aβ in AD mice. Importantly, Y-5A15 vaccination successfully reduced Aβ levels, plaque burden and glial activation, rescued synaptic deficits and significantly ameliorated memory and cognitive decline in APP/PS1 transgenic mice, suggesting that the yeast-based Aβ epitope vaccine has a promising potency for the treatment of AD.

Authors: See Lay Shien , Calo Luke , Bannon Benjamin , Opdyke Aaron
Published: July 2020

Urban flooding in developing countries represents a growing threat to sustainable development efforts, yet the tools needed to study these infrastructure systems in data-scarce environments are woefully inadequate. This study seeks to propose a standardized approach and methods for mapping urban drainage systems in developing communities. The research draws on a case study from the Philippines, which sought to conduct rapid elevation surveys and drainage assessments employing open source geographical information system (GIS) tools. We develop a standardized procedure for digitizing drainage systems using OpenStreetMap and Field Papers, as well as discuss applications of this data for drainage design. The results contribute to a methodological framework that can be replicated in other similar developing communities where study of urban drainage is needed for sustainable development and disaster risk reduction efforts.
Supplied Sediment Tracking for Bridge Collapse with Large-Scale Channel Migration
Authors: Inoue Takuya , Mishra Jagriti , Kato Kazuo , Sumner Tamaki , Shimizu Yasuyuki
Published: July 2020

Here, we provide a numerical model that assigns an identification number to trace sediments and also identify the source of sediment supply. We analyze the efficacy of our model by reproducing the reach-scale field observations from flooding events in 2010 and 2016 that affected Kyusen Bridge over the Bebetsu River, Hokkaido, Japan. Our simulation results can successfully reproduce and trace the formation of bars caused by sediment supply in the study region. Our study also suggests a strong relationship between bank erosion rate, sediment supply and flow-discharge. The bank erosion rate is higher when sediment supply increases, and bank erosion reduces as flow discharge goes down. The model can also replicate the changes in a bed concerning sediment supply and was used to reproduce the bridge-abutment failure caused by the 2016 flooding with large sediment supply and the bridge-pier failure caused by the 2010 flooding with less sediment supply.

Authors: Chowdhury Forhad H , Haque Mohammod Raziul , Muhammad Rumi Jalaluddin , Hakim Maliha , Khan Sharif Uddin , Sarker Mainul Haque
Published: July 2020

Background: Even after the failure of EC-IC bypass trial, EC- IC bypass can help many patients in preventing future stroke. Here we present a case series of patients with cerebral ischemia from different etiological modes who underwent EC-IC bypass with positive end results.
Methods: Patients in these cases series with TIA/stroke/recurrent stroke were evaluated clinically for the history of TIA or recurrent/hemodynamic TIA (in rest or during work) or progressive hemiparesis/aphasia/visual disturbances or sudden hemiplegia/hemiparesis/aphasia with subsequent significant (days to a week) recovery. MRI of the brain was done in ischemic protocol in all cases. To see the arterial pathology dynamic CTA was also done in all cases except one case. DSA was done in 03 cases. When clinical features, cerebral ischemia on MRI and arterial stenosis/occlusion on angiogram were concordant with each other, only then cerebral revascularization was done. After bypass, all patients were followed up regularly. All recorded data were reviewed retrospectively.
Results: Total no. of cases were 08. The most common presentation was hemiparesis. Etiologies were infective thrombosis of ICA, orbital cellulitis, thrombosed giant ICA aneurysm, single & multiple vessel occlusion and MCA stenosis. High flow EC-IC bypass was done in one case. STA- MCA bypass was done in rest of the cases. All patient were ambulant with static neuro-status without new stroke till last follow up. All bypasses were patent and functioning till last follow up (clinical, Doppler/Imaging).
Conclusion: In carefully selected cases cerebral revascularization in ischemic conditions can result positive outcome.

The Conspiracy of Brainwashing: the Experiences of the First and the Second Cold War
Authors: Aleknonis Gintaras
Published: July 2020

With the recent rise of a new confrontation between the East and the West, the convergence of different understandings of brainwashing emerges as a problem of political communication and poses a challenge for information security. The principle objective of this paper is to present a contemporary understanding of brainwashing, determine its propaganda potential, and provide educated guesses about successor concepts, which could be traced back to the origins of brainwashing. Therefore, the article describes the ‘classical’ Western understanding of brainwashing; looks for the potential equivalents of brainwashing on the other side of the Iron Curtain; reveals the rebirth and transformations of the concept in post-communist countries during the period of time, when brainwashing in the West had already came out of fashion; notes to the potential misunderstandings between the new and old democracies, which arise because of the different interpretation of brainwashing.The contemporary comprehension of brainwashing continues to alternate between instrumental and political understanding. The broadened concept becomes more blurred, although the lack of precision compensates the potential loss of mystery and allows the brainwashing to preserve an image of an almighty technique.
Transformation of the Europe’s Concept in WWII Speeches by Russian Presidents (2004-2019)
Authors: Steblyna Nataliia
Published: July 2020

Historically, the Europe’s concept in Russian state discourse has been constantly transforming, due to current events. Nowadays, the concept’s understanding can’t be described without WWII topic – obviously a crucial point in the modern Russian ideology. To explore the image of Europe in this discourse, the speeches of the Russian presidents given on the 9th of May from 2000 to 2019 were content analyzed. The transformations of Europe in the Russian state discourse about WWII as were as Europe’s roles in the WWII were defined. Up to 2009 the differentiation between the post-Soviet countries and “far abroad” Europe was constantly used. After the Russo-Georgian war, and mostly after the annexation of Crimea and the war in Donbas, the construction of a bipolar world started. Russian isolation can be observed in 2010-2019. Europe’s roles have been changing. In early Putin’s speeches (2000-2003) this topic seems not to be significant. Before 2008 Europe was described as both active and passive in the war. Afterwards “passiveness” prevailed. Thus, in the Russian state discourse, after 2008 the WWII was used to show the opposition between active/strong Russia and passive/weak Europe, which provide threats to peace on the planet.

Authors: Rezayi Adel , Razavilar Vadood , Mashak Zohreh , Anvar Amirali
Published: July 2020

Background: Considering the high fatality of botulism, the control of Clostridium botulinum and its neurotoxins has clinical importance. In this regard, using chemical preservatives, natural essential oils (Eos), and changes in the growth predisposing factors of bacteria are suitable methods to control the growth and toxin producing of C. botulinum in foods. Objective: The current survey was done to assess the effects of Citrus sinensis EO and intrinsic and extrinsic factors on the growth and toxin producing of C. botulinum type A. Materials and Methods: In this experiment with a factorial design, C. sinensis EO (0.0%, 0.015%, 0.03%, and 0.045%), nisin (0, 500, and 1500 IU/mL), nitrite (0, 20, and 60 ppm), pH (5.5 and 6.5), storage temperature (25 and 35° C), and sodium chloride (NaCl, 0.5% and 3%) were used to assess bacterial growth in the brain heart infusion medium. Finally, the mouse bioassay method was also used to assess toxicity. Results: Clostridium sinensis EO with a concentration of 0.045%, as well as the reduction of pH and temperature could significantly delay the growth of bacteria (P≤0.05) in contrast to the use of NaCl and nisin alone. However, all concentrations of sodium chloride (NaCl), nisin, and C. sinensis EO (< 0.045%) in interaction with each other, especially in combination with nitrite, showed good synergistic effects. Conclusion: These results suggested that using certain concentrations of C. sinensis EO and nisin, along with other suboptimal factors caused a significant decrease in the nitrite contents of foods with a significant reduction in the growth and toxin-producing ability of C. botulinum.

Published: July 2020

Background: Pseudomonas aeruginosa and Acinetobacter baumannii are widely ubiquitous in nature. In addition, they are opportunistic pathogens for humans and the common cause of nosocomial infections. Objective: Due to the increased antibiotic resistance in the treatment of nosocomial infections, this study aimed to evaluate the antibiotic susceptibility pattern of P. aeruginosa and A. baumannii in the pediatrics intensive care unit (PICU). Materials and Methods: Totally, 280 clinical samples from PICU patients were evaluated in this study. The samples were examined for P. aeruginosa and A. baumannii using standard microbiological methods. Finally, the Epsilometer test method was performed to investigate the antibiotic susceptibility pattern of these bacteria. Results: The results revealed a total of 21 isolates (7.5%) of P. aeruginosa and 11 isolates (3.9%) of A. baumannii. P. aeruginosa isolates showed the highest susceptibility to colistin (85.7%) and gentamicin (66.7%) while A. baumannii isolates were more susceptible to colistin (100%), ceftazidime (54.5%), and amikacin (45.5%), respectively. Conclusion: Due to the antibiotic susceptibility patterns of bacterial isolates in the recent study, colistin and gentamicin are recommended for the treatment of P. aeruginosa infections and colistin, ceftazidime, and amikacin are suggested for A. baumannii infections.

Published: July 2020

Background: Common methods for identifying the infectious bacteria in human urine are mainly time-consuming and costly. Therefore, the most reliable method for detecting the urinary tract infections is the urine culture, which requires at least 48 hours to identify infectious factors. Objectives: It is important to detect the bacteria in urine rapidly, simply, and accurately. Materials and Methods: In this work, the variations in the electrical conductivity and dielectric coefficient of the urine sample due to changes in the concentration of infectious bacteria have been studied. Furthermore, an appropriate measurement system was prepared for impedancemetry and conductometry. Results: We showed that the detection time was reduced to about an hour. Finally, the accuracy of the device for diagnosis and precision of measurement were evaluated and compared by the detection method for bacterial culture. Conclusion: In this work, the detection time was reduced to about 1 hour.

Introduction: Given the harmful effects of insomnia and the need for a better understanding of the disorder as well as providing proper care, the present study aimed to compare the emotional dysregulation and experiential avoidance in patients with insomnia and non-clinical individuals. Methods: To conduct the present cross-sectional study, two sample groups were selected randomly. The first group consisted of 100 patients with insomnia who visited the Sleep Disorders Research Center at Farabi hospital in Kermanshah, Iran. The second group consisted of 100 administrative staff of Kermanshah University of Medical Sciences (KUMS) without sleep problems. For data collection, three questionnaires were used: Difficulties in Emotion Regulation Scale (DERS), Pittsburgh Sleep Quality Index (PSQI), and Experiential Avoidance Questionnaire (EAQ). The data were analyzed through the analysis of variance, using the SPSS version 13. Results: The total mean score of difficulties in emotion regulation in patients with insomnia and non-clinical people measured 101.18 (45.60) and 86.77 (21.88), respectively, and the mean scores of experiential avoidance measured 37.53 (12.33) and 28.74 (21.88) in patients with insomnia and non-clinical people, respectively. The results of the present study revealed that there was a significant difference between the two groups in terms of emotional dysregulation and experiential avoidance. Conclusion: According to the current results, it is suggested that therapists consider the role of emotional dysregulation and experiential avoidance in the treatment and care of chronic insomnia. To solve these problems, it is recommended third-wave therapies be used, especially acceptance and commitment therapy.

Published: July 2020

Introduction
: Coronary artery calcium score (CACS) and carotid artery intima-media thickness (CIMT) are the markers of atherosclerosis. An association between CACS and CIMT with presence of atherosclerotic coronary artery disease (CAD) is well established. However relationship between severity of CAD with CACS and CIMT is less clear. This study aimed to investigate the correlation between severity of CAD assessed by SYNTAX and Gensini scores with CACS and CIMT. Methods: This prospective study was conducted on 351 patients with CAD between June 2015 to December 2016. CACS was obtained using AGATSTON algorithm with 128 slice multidetector computer tomography (MDCT) before conventional coronary angiography (CCA). CIMT was measured by using Philips IE33 Echo machine. The severity of CAD was assessed by SYNTAX score (SS) and Gensini score on CCA. Correlation between severity of CAD with CACS and CIMT was analysed. Results: Mean CACS was 241.5±463.7, and this was positively correlated with over all SS (r=0.417, P<0.0001) and Gensini score (r=0.405, P<0.0001). Mean CIMT was 0.80±0.18 mm and this was also significantly correlated with SS (r=0.450, P<0.0001) and Gensini score (r=0.459,<0.0001). Multivariate analysis showed that CACS was independently associated with diabetes mellitus (β:0.11, P=0.021), SS (β:0.251, P=0.010) and mean CIMT (β:0.128, P=0.028). Receiver-operating characteristic (ROC) curve analysis revealed a cut off CACS of >493 for SS≥33 (high-SS tertile). Conclusion: Our study confirmed a significant correlation between CACS and CIMT with the severity of CAD assessed by SS and Gensini scores. CACS and CIMT may be considered as important noninvasive diagnostic modalities in the assessment of the severity of CAD.

Published: July 2020

Introduction
: Studies found that the inflammation plays a key role in the pathogenesis of paroxysmal atrial fibrillation (PAF). It is well-known that apolipoprotein-A1 (Apo-A1) demonstrates antiinflammatory and anti-oxidant properties in a healthy physiological system. In the present study, we aimed to determine whether there is any difference of Apo-A1 levels in patients with PAF and healthy subjects. Methods: In this prospective cohort study, we enrolled a total of 35 PAF patients and 34 comparable healthy participants. Apo-A1 levels were measured from each subject using an immunophelometric method. All enrolled subjects were followed-up for one year during the study period. Results: Serum high-sensitivity C-reactive protein (hs-CRP) levels were statistically higher in PAF patients compared to healthy subjects (1.54±1.99 vs. 1.06±2.01, P= 0.016, respectively). Of note, patients with PAF had lower Apo-A1 levels (1.84±0.74 vs. 2.55±0.44, P= 0.001, respectively). There was no statistical difference between the groups in terms of apolipoprotein-B levels (1.08±0.36 vs. 0.99±0.38, P= 0.339, respectively). We did not find any correlation between Apo-A1 levels and PAF attacks in the study. Conclusion: The main finding of this study was that Apo-A1 levels were significantly lower in PAF patients compared to healthy participants. Based on our results, we considered that Apo-A1 may have a key role in the pathogenesis of PAF.

Published: July 2020

Drawing on an ethnographic monitoring engagement with Kichwa intercultural bilingual educators in the Peruvian Amazon, we argue for ethnographic monitoring as a method and the continua of biliteracy as a heuristic for mapping biliteracy teaching in Indigenous contexts of bilingualism. Through our mapping, we uncover tensions in the teaching of majoritized languages in Indigenous contexts of postcoloniality, challenge constructs of student shyness, and propose pedagogies to support the flourishing of student voice in bilingual education.

Penelitian ini bertujuan melihat perubahan abrasi pantai yang terjadi di Aceh Barat. Abrasi pantai dapat diakibatkan oleh perubahan alam dan kegiatan manusia. Diantara faktor yang diakibatkan oleh perbuatan manusia adalah bangunan buatan seperti groin, jetty, breakwater pelabuhan dan reklamasi yang sejajar garis pantai, dibangunnya dam di sebelah hulu sungai dan sudetan (pemindahan arus sungai), penambangan pasir di perairan pantai, dan pengambilan pelindung pantai alami, yaitu penebangan hutan mangrove dan pengambilan terumbu karang. Hasil analisis data angin pada bulan Mei 2016 menunjukkan arah angin berasal dari barat laut menuju daratan yang memiliki nilai tersesar yaitu 48,% dengan kecepatan angin 4-7 knots. Berdasarkan data tinggi gelombang terbesar terjadi pada keadaan moderate sea yaitu sebesar 1,225-2,5 m dengan periode 8,77 detik. Kondisi tersebut menunjukkan keadaan normal di pesisir pantai yang tidak mengakibatkan abrasi secara besar. Kondisi meteorologi tersebut memiliki nilai yang hampir sama pada lokasi penelitian A (jauh dari bangunan laut) dan B (dekat dengan bangunan laut). Hasil analisis angkutan sedimen dapat digunakan untuk menilai seberapa besar perubahan garis pantai terjadi setiap tahunnya. Hasil analisis sedimen tersebut menunjukkan bahwa dalam waktu enam belas tahun, laju angkutan sedimen sejajar pantai sebesar 2.043.475,13 m3. Arah dominan sedimen menuju ke arah Timur. Potensial laju angkutan sedimen sejajar pantai tahunan sebesar 127.717,20 m3. Sesuai dengan kondisi dilapangan terjadi kemunduran garis pantai dan pendangkalan muara sungai meureubo

Tawes (Puntius javanicus) is one of the freshwater fish species that has economic value in Aceh. One of the obstacle in tawes fish breeding is Saprolegnia sp. fungus that attacks tawes fish eggs. The necessary solutions  was needed to resolve fungal infection by using Tagetes erecta L. Therefore this research was very important to control fungal infections on fish eggs Saprolegnia sp.. This study used Randomized Complete Design with four treatments and three raplications for each treatments. The treatment in this study namely P0 = P1 = ppm, 40 ppm, P2 = 50 ppm, P3 = 60 ppm, and P4 = 70 ppm. The parameters observed in this research is the prevalence of eggs hatchability rate, eggs growth and water quality. The results of this study showed that the highest value of tawes eggs hatchability (prevalence) found in treatment 3 (P3 = 60 ppm) was 53.33% and the lowest value was present in control treatment (P0 = 0 ppm) was 36.66%. The reasults of eggs hatchability rate (HR) show the highest values found in treatment 2 (P2 = 50 ppm) of 95.66% and the lowest value is present on the control (P0 = 0 ppm) of 45.66%. On the egg development stage shows that there is a embryogenesis process starts from cleavage, morula, blastula, gastrula, organogenesis to become larvae. Water quality during the research shows that water temperature range were 29.2-30oC, and DO water range were 3.6-4.8 mg/l.

Development of human resources is very important in promoting economic growth, because humans are not only objects in development but also play a role as a subject. Stunting is a major problem that inhibits the quality of human resources, to reduce the amount of human development that lives by stunting is to increase the consumption of protein contained in fish. This study aimed to determine the pattern of fish consumption in Central Aceh and the variables that affect fish consumption. The analytical model used is the granger causality analysis, through the Vector Error Correction Model (VECM) analysis model. The results of this study indicate that the pattern of fish consumption in Central Aceh was not only influenced by income, but also influenced by the amount of chicken meat and egg consumption Increased income does not have a positive effect on increasing fish consumption but affects the amount of chicken meat and egg consumption. To increase the amount of fish consumption in Central Aceh, efforts to increase the amount of fish supply through local fish farming activities and the socialization of fish eating.

Міфологічні структури медійних текстів: основний зміст та специфіка впливу
Authors: Deviatko Nataliia
Published: July 2020

У статті досліджуються зміст та специфіка впливу медійних текстів на світогляд людини, коли їхні структури актуалізуються за міфологічними принципами. Аналіз проблеми відбувається на основі порівняння спільних і відмінних характеристик масової комунікації і комунікації, яка набуває міфологічних ознак у контексті мас-медійного дискурсу. Відзначається, що у сучасному світі засоби масової інформації виконують основну функцію каналізації почуттів, вражень та очікувань масової свідомості та мають значний вплив на формування соціальних груп та суспільства. На своєму структурному рівні спілкування засоби масової інформації всіх типів використовують міфологічні принципи передавання інформації, а також кодування та розшифрування значень, які мають емоційно важливе навантаження. Важливо зрозуміти принципи того, в який спосіб виражені та приховані значення в текстах ЗМІ вкладаються у світогляд, спрямовують людські дії та коригують людське сприйняття як політичних, так і культурних явищ. У статті досліджено зміст та вплив фокусу, який медіатексти набувають, коли їх структури актуалізуються відповідно до міфологічних принципів.Описуються базові характеристики медійного тексту як комунікативного феномена впливу на світогляд особистості і великі аудиторії. Окрема увага приділена дослідженню взаємовпливу головних структурних особливостей національного, культури, політики і медіа.

The objective of this study is to investigate the methods to create durable self-cleaning textiles by coating fabrics with
TiO2-(1%)Fe-N-graphene (2%). To improve the adherence of the nanoparticles, the polyester/cotton woven fabrics were
pre-treated with polyacrylic acid (PA), carboxymethylcellulose (CMC) and polyethylene polyamine resin (EZF). The
pre-treated materials were immersed in a doped TiO2 for 30 minutes at 40oC and dried at 125oC. The finished fabrics
were stained with methylene blue dye and exposed to visible light.
The SEM images show the presence of particles on polymers layers firmly attached on the material surface. The
treatments determine the decrease of the exothermic peak (452.48oC), characteristic of the cellulose decomposition,
demonstrating an increase of the thermal conductivity of the materials. The doped TiO2-graphene induces a double
degradation of methylene blue in comparison with untreated material and the materials treated with CMC, polyacrylic
acid and cationic polymer. The effect is maintained after washing
