Published: May 2020

Abstract
Background Video consultations are promoted as a tool to effectively supplement paediatric diabetes outpatient care. However, knowledge about attitudes of diabetes professionals towards this new technology is lagging behind. Diabetologists and diabetes nurses participating in a controlled study (the VIDIKI study) with monthly video consultations for children with type 1 diabetes were interviewed about their experience with this type of communication.
Research Design and Methods Guideline-based qualitative interviews with 9 telemedicine experts (7 paediatric diabetologists and 2 diabetes nurses) and 7 paediatric diabetologists who agreed to the telemedical co-treatment of their patients were analysed using qualitative content analysis, in particular inductive category formation.
Results Diabetes experts reported generally positive attitudes towards video consultations. They identified a number of unique benefits of telemedical interventions, including higher frequency of contacts, greater sense of patient´s safety, ability to interact with patients in their own homes, more timely and accurate medical monitoring, and improved data management. Additionally, it was important to the experts to maintain regular face-to-face consultations and to ensure close communication between telemedicine and outpatient clinical experts.
Conclusions Prerequisites for successful video consultations include a comprehensive initial technical training and an agreement on treatment responsibilities of all health care professionals involved in the patient’s care. Under these conditions, the experts reported significant advantages of video consultation in the treatment of children with type 1 diabetes.

Authors: Suzuki Mayumi , Shibahara Takuma , Muragaki Yoshihiro 
Published: May 2020

Abstract
Background Although advances in prediction accuracy have been made with new machine learning methods, such as support vector machines and deep neural networks, these methods make nonlinear machine learning models and thus lack the ability to explain the basis of their predictions. Improving their explanatory capabilities would increase the reliability of their predictions.
Objective Our objective was to develop a factor analysis technique that enables the presentation of the feature variables used in making predictions, even in nonlinear machine learning models.
Methods A factor analysis technique was consisted of two techniques: backward analysis technique and factor extraction technique. We developed a factor extraction technique extracted feature variables that was obtained from the posterior probability distribution of a machine learning model which was calculated by backward analysis technique.
Results In evaluation, using gene expression data from prostate tumor patients and healthy subjects, the prediction accuracy of a model of deep neural networks was approximately 5% better than that of a model of support vector machines. Then the rate of concordance between the feature variables extracted in an earlier report using Jensen–Shannon divergence and the ones extracted in this report using backward elimination using Hilbert–Schmidt independence criteria was 40% for the top five variables, 40% for the top 10, and 49% for the top 100.
Conclusion The results showed that models can be evaluated from different viewpoints by using different factor extraction techniques. In the future, we hope to use this technique to verify the characteristics of features extracted by factor extraction technique, and to perform clinical studies using the genes, we extracted in this experiment.
Selected Research Topics of the Dondoni Group over the Last Two Decades (2000–2020)
Authors: Dondoni Alessandro 
Published: May 2020

From a selection of research topics carried out in our laboratory during the last twenty years it becomes apparent that our main target was the discovery of new or improved synthetic methods together with new properties. Our efforts were made with the aim of being of some utility to other fields of research, with particular emphasis to glycobiology and heterocyle-based bioorganic chemistry. We performed new chemistry mainly in the field of carbohydrate manipulations taking as a primary rule the simplicity and efficiency manners. Toward this end, modern synthetic tools and approaches were employed such as heterocyle-based transformations, multicomponent reactions, organocatalysis, click azide–alkyne cycloadditions, reactions in ionic liquids, click photoinduced thiol-ene coupling, and click sulfur–fluoride exchange chemistry. With these potent methodologies in hand, the syntheses of carbohydrate containing amino acids up to proteins glycosylation were performed.1	Heterocyclic Glycoconjugates and Amino Acids2	Triazole-Linked Oligonucleotides: Application of Click CuAAC3	Non-Natural Glycosyl Amino Acids4	Non-Natural Oligosaccharides5	Calixarene-Based Glycoclusters6	Carbohydrate-Based Building Blocks7	Homoazasugars and Aza-C-disaccharides8	Synthesis of Glycodendrimers9	Peptide and Protein Glycoconjugates10	Conclusions
Language policy and the law
Authors: Edwards Alison 
Published: May 2020

AbstractUniversities in the Netherlands are currently faced with finding a balance between the implementation of English-medium instruction and the protection and promotion of Dutch. In this article I analyse university language policy documents from a discursive and critical perspective. I explore the intertextual transformations involved in a multilevel process of policymaking; that is, as policy discourse shifts from the state legislation governing the language of instruction in higher education to the codes of conduct for language of the publicly funded universities. The institutions use various discursive strategies, including intertextuality and recontextualisation, to legitimate their reinterpretation of the basic legal principle ‘Dutch, unless’ as ‘English, unless’ (at master’s level, and increasingly at bachelor’s level too). Although the current law is set to be amended, it appears the proposed new law will simply require universities to do more paperwork while continuing on their current path.
The weakening of intervocalic /d/ in the Spanish of Las Palmas de Gran Canaria
Authors: Samper Padilla José Antonio , Samper Hernández Marta 
Published: May 2020

Abstract
The present paper compares the results obtained from the analysis of intervocalic /d/ in Las Palmas de Gran
Canaria with those of other PRESEEA research groups (four Spanish groups and a Latin American one). The Spanish of the Canary
Islands is placed, as in other phenomena, halfway between Peninsular and Latin American Spanish. In this process of weakening,
interdialectal differences in the degree of deletion of /d/ in participles and the determiner todo stand out,
together with some virtually Panhispanic characteristics. The differences in the weakening of the obstruent in these two contexts
are closely related to the frequency of their use in the different communities.
Convergences and divergences inthe use of the diminutive in Medellin, Caracas and Madrid
Authors: Malaver Irania , Paredes García Florentino 
Published: May 2020

Abstract
This article analyzes the differences and coincidences in the uses of the diminutive found in three varieties of
Spanish. Based on the classification of the pragmatic functions of the diminutive by Reynoso
(2003), and the analysis of 5355 cases of non-lexicalized diminutives, it may be observed that the three varieties
converge greatly in the production of the diminutive forms of -ito. There is some divergence in the variety of
lexical bases that support the diminutive since the people of Madrid use (and listen to) more diminutives than Americans, but they
use (and listen to) them in a smaller number of different words. The social factors contained in the sample have shown a reduced
effect on the functions of the suffix, and a partially differentiating behavior among the three communities: in Caracas, age has a
strong influence on the functions while, in Madrid and Medellin, the level of education is the factor that exerts more influence
on these functions.
Uses and resources of mitigation, in contrast
Authors: Cestero Mancera Ana M. 
Published: May 2020

AbstractMitigation is a highly complex pragmatic phenomenon which has been prioritized as a subject of study in recent decades. However, because of this complexity, there is still neither a convincing definition of exactly what mitigation is nor a definitive list of the linguistic and non-verbal resources through which it is carried out. For this reason, several empirical studies which seek to explain sociopragmatic and geolectal variability in the uses and strategies of mitigation are under way. This is also the aim of our paper, included in theProject for the Sociolinguistic Study of Spanish from Spain and America(PRESEEA). In it, we present relevant data obtained from the comparison of what occurs in Madrid, Valencia, Las Palmas de Gran Canaria and Puebla (Mexico) regarding the frequency of the production of mitigation and its function in transactional interaction, together with the most productive strategies used in each community. This enables us to identify convergences and divergences and pinpoint sociopragmatic and geolectal patterns.
A novel training-free recognition method for SSVEP-based BCIs using dynamic window strategy
Authors: Chen Yonghao , Yang Chen , Chen Xiaogang , Wang Yijun , Gao Xiaorong 
Published: May 2020

Abstract

Objective. Filter bank canonical correlation analysis (FBCCA) is a widely-used classification approach implemented in steady-state visual evoked potential (SSVEP)–based brain computer interfaces (BCIs). However, conventional detection algorithms for SSVEP recognition problems, including the FBCCA, were usually based on ‘fixed window’ strategy. That’s to say, these algorithms always analyze data with fixed length. This study devoted to enhance the performance of SSVEP-based BCIs by designing a new dynamic window strategy which automatically finds an optimal data length to achieve higher information transfer rate (ITR). Approach. The main purpose of ‘dynamic window’ is to minimize the required data length while maintaining high accuracy. This study projected the correlation coefficients of FBCCA into probability space by softmax function and built a hypothesis testing model, which took risk function as evaluation of classification result’s ‘credibility’. In order to evaluate the superiority of this approach, FBCCA with fixed data length (FBCCA-FW) and spatial temporal equalization dynamic window (STE-DW) were implemented for comparison. Main results. Fourteen healthy subjects’ results were concluded by a 40-target online SSVEP-based BCI speller system. The results suggest that this proposed approach significantly outperforms STE-DW and FBCCA-FW in terms of accuracy and ITR. Significance. By incorporating the fundamental ideas of FBCCA and dynamic window strategy, this study proposed a new training-free dynamical optimization algorithm, which significantly improved the performance of online SSVEP-based BCI systems.

Abstract
at present, the potential for sago starch has not optimally been utilized. The characteristic of this starch is the main problem in using it as industrial raw material. One of efforts to increase the added value of starch is to modify it in the form of starch nanoparticles. Therefore, finding the best and cheapest practice to produce it will a big advantage. One way to do it is by modifying the technique that has already existed. This research is aiming, first to find the best and optimal technique to produce sago starch nanoparticles by combining hydrolysis with precipitation technique and second, calculating the yield and characteristics of sago starch nanoparticles produced from this method. The result showed that hydrolysis−precipitation combination method has succeeded to produce sago starch nanoparticles. The optimum variable was 12 hours hydrolysis, precipitation by ethanol, with produced 25% yield and 21,98 nm particles size. Type of nano particle that is produced is amorf with 41% crystalline. Starch nanoparticle is utilized for reinforcing bioplastic. Eventhough, the results show a potential technique on producing sago starch nanoparticles, but there are still a lot to be done to find the best way to produce it in mass production.

Abstract
21st century learning plays an important role in producing quality human resources, in order to have global competitiveness. Among the competencies students must have is new literacy, as an extension of scientific literacy that has been proclaimed by the previous government. New literacy includes data literacy, technology literacy and human literacy. Besides that, students also need to have disaster literacy, because Indonesia is located in an area prone to disasters. This study aims to determine the scientific literacy (conceptual understanding) of students, and knowing the extent of integrating new literacy and disaster literacy into learning in schools. The type of research conducted is survey research. The instruments used were concept tests, learning observation sheets, interview guides for teachers, and textbook analysis sheets. The concept test was given to 78 class XI students from three different schools, and interviews were conducted with 3 physics teachers in the three schools. Book analysis was performed on 5 physics textbooks that are widely used in schools. Data are analyzed quantitatively and qualitatively. The results showed that learning in schools is still traditional or teacher-centered learning. The integration of new literacy and disaster literacy in the learning process and textbooks used is still low. Understanding of student concepts is also low and misconceptions occur. Therefore, the recommendation from this preliminary study is the need to develop physics teaching materials that integrate new literacy and disaster literacy, and can improve students’ understanding of concepts according to the demands of the 21st century.

Abstract
“Alam takambang jadi guru” is a Minangkabau philosophy that is suitable implemented in the learning process. Nature tourism in Indonesia is very supportive for the implementation of contextual physics learning, one of which is Bukik Chinangkiek Edupark. Bukik Chinangkiek has natural conditions and rides related to physics for example rotational dynamics but it has not been utilized in physics learning. This study aimed to analyze the potential of Bukik Chinangkiek as an edupark-based learning resource for physics. Analysis was carried out with the Plomp development model at the preliminary analysis phase. The data of this study were obtained from questionnaires and interviews along with teachers and students in high schools throughout X Koto Singkarak Subdistrict, while concepts relevant to physics subject matter were obtained from direct observation of Bukik Chinangkiek Edupark. The technique of data analysis was descriptive percentages. Analysis shows that learning physics has not been integrated into the surrounding natural environment so students have not understood the concept of contextual physics and most students tend to use IT in learning. The results of this study is intended to be used as the basis for developing digital book of edupark (e-book) for high school.

Abstract
As an archipelago country, Indonesia has many beach lines which are the fourth-longest in the world, and in fact, the coastal areas had damaged by some natural phenomena, such as abrasion. One of the available strategies which would give an understanding of abrasion is integrating this disaster knowledge in a certain lesson at school. Physics is one of the subjects which is suitable to give understanding about abrasion. This is because physics includes various disaster phenomena. The effort to do this is achieved by an e-book. Developing a physics e-book with abrasion theme, it is necessary to analyse the student’s knowledge about abrasion. This study used the descriptive method, and the subjects are those who live near a coastal area, Senior High School 1 Nan Sabaris students. Samples were selected by random sampling techniques. The student’s prior knowledge was tested by a questionnaire that consisted of eleven questions. From the analysis, it can be said that student’s prior knowledge about abrasion can be categorized as a low level, in the C rate (Enough). This result shows that the physics e-book using abrasion theme need to be developed.
