Authors: Munarriz Pablo M. , Pascual Beatriz , Castaño-Leon Ana M. , García-Recuero Ignacio , Redondo Marta , Aragón Ana Martínez de , Romance Ana
Published: October 2020

Background:

Apert syndrome is one of the most severe craniofacial disorders. This study aims to describe the craniofacial surgeries and central nervous system malformations of a cohort of children with Apert syndrome treated in the past 20 years and to compare these data with previously published data.

Methods:

Retrospective analysis of a series of patients with Apert syndrome treated between 1999 and 2019 in our hospital. Information was analyzed regarding craniofacial procedures, hydrocephalus and presence of shunts, Chiari malformation Type 1, and other brain malformations such as corpus callosum and septum pellucidum anomalies.

Results:

Thirty-seven patients were studied. Ventriculoperitoneal shunt prevalence was 24.3%, and 8.1% of patients required decompressive surgery for Chiari malformation. All of them needed at least one cranial vault remodeling procedure. The median age for this procedure was 8 months. In 69.7% of patients, the first cranial vault intervention was performed in the fronto-orbital region. In 36.4% of patients, a midface advancement had been performed at the time of this review, although this proportion was very dependent on the follow-up period and the age of the patients. The median age for the midface advancement procedure was 5.25 years. Anomalies of the corpus callosum and the septum pellucidum were reported in 43.2% and 59.5% of patients, respectively.

Conclusion:

Apert syndrome is a type of syndromic craniosynostosis, and patients usually require one or more cranial and facial surgeries. In comparison with other syndromic craniosynostosis types, Apert syndrome less frequently requires a VP shunt or treatment for a Chiari malformation.
The market landscape of online second opinion services for spine surgery
Authors: Lien Brian V. , Brown Nolan J. , Gattas Sandra , Choi Elliot H. , Sahyouni Ronald , Campos Jessica K. , Zhang Angie , Oh Michael Y.
Published: October 2020

Background:

The aim of this study was to identify patient interest in second opinion services online and identify the options patients have in obtaining second opinions from spine surgeons in the United States.

Methods:

We utilized Google Trends (i.e., search data since 2010) to ascertain the level of interest in receiving second opinions for spinal surgery. In addition, we contacted the top 30 hospitals for neurology and neurosurgery in the U.S. News rankings by phone to obtain information regarding when/how and at what cost they provide second opinions for spine surgery.

Results:

The cost of the second surgical opinions averaged $493 (±$343) USD (range $90–$1,300); the time to receive a second opinion averaged 20 (±19) days (range 1 day–5 months). Remote or “online second opinion” programs charged an average of $643 (±$259) USD (range $100–$850), and the time to receive an “online second opinion” averaged 14 (±7) days (range 1–4 weeks).

Conclusion:

Although second opinions have been shown to be beneficial to patients, ambiguous or high costs and long wait times may serve as barriers for certain groups (i.e., uninsured or underinsured) and potentially diminish the quality of care.
High-grade spheno-orbital meningioma in patients with systemic lupus erythematosus: Two case reports and literature review
Authors: Abdulqader Sarah Bin , Almujaiwel Nasser , Alshakweer Wafa , Alzhrani Gmaan
Published: October 2020

Background:

Spheno-orbital meningiomas (SOMs) are often benign. The association of meningioma and systemic lupus erythematosus (SLE) is rarely discussed in the literature. Here, we report two patients with high-grade, SOMs with a prolonged history of SLE and review the literature.

Case Description:

The first case is a 52-year-old female patient with a 15-year history of SLE diagnosis who was referred to our center with a 1-year history of proptosis and excessive tearing of the left eye. This patient was operated for the left SOM with histopathological diagnosis of the World Health Organization (WHO) Grade III rhabdoid meningioma. The second case is a 36-year-old female patient with a 12-year history of SLE diagnosis who presented to our clinic with a 5-year-history of progressive right eye proptosis and occasional headaches. She was operated for the right SOM with histopathological diagnosis of the WHO Grade II chordoid meningioma.

Conclusion:

Rhabdoid and chordoid SOMs are uncommon and no previous report discussed their occurrence in patients with SLE. The association of high-grade meningiomas and SLE deserves further exploration.

Amongst the less recognized children literature authors of the 19th century The article describes the figures of two authors from the turn of the century that are nearly forgotten today: Zofia Bukowiecka and Jadwiga Chrząszczewska-Trzeciakowa. In their literary works directed at children and adolescents, they tried to combine both the educational values and the thrilling plot. Both authors can be classified as minorum gentium writers. They lived and created during the similar period and belonged to the remarkable generation from the turn of the century. The article makes attempt at the comparative analysis of both the novels of manners and the historic works of both writers. Additionally, it resolves the debatable matters of the biographical nature which arose among the figures of the two authors.

TOP-N53: A Clinical Drug Candidate for the Treatment of Non-healing Wounds
Authors: Naef Reto , Tenor Hermann , Koch Guido
Published: October 2020

Chronic non-healing wounds impose a huge burden on patients and health care providers. In spite of improvements in standards of care there are no effective and safe treatments that promote new tissue formation and wound closure in ailments such as diabetic foot ulcer, pressure ulcer,
venous leg ulcer or digital ulcer in systemic sclerosis. Endothelial dysfunction, which associates with impaired endogenous nitric oxide formation is assumed to be a main disease mechanism in chronic, non-healing wounds in diabetic and elderly patients as well as in digital ulcers in systemic
sclerosis. Topadur Pharma has invented small molecular weight nitric oxide-releasing PDE5 inhibitors, which by modulating a key enzyme system of intracellular signaling may address chronic non-healing wounds. The promising first drug candidate TOP-N53 is currently in early clinical development.
Here we describe for the first time the design of TOP-N53 and the synthesis of the clinical GMP batch.
Das Oratorium im Spannungsfeld der Konfessionen: Zum interkonfessionellen Austausch von Oratorien im 18. Jahrhundert
Authors: Haiawi Maryam
Published: October 2020

The present study deals with interconfessional exchange of oratorios in German-speaking countries during the 18th century. In doing so, it pursues the goal of focusing on the question of the denominational or non-denominational nature of the sacred music genre, a question that has so far been insufficiently discussed in musicological and literary research. It analyses selected oratorios between 1715 and 1781 which were written at important contemporary musical locations and were received interdenominationally (Hamburg, Leipzig, Brunswick, Catholic imperial court of Vienna, Catholic Saxon court at Dresden). The study comes to the conclusion that the oratorio of the 18th century was not defined solely by its denominational orientation, but influenced by a number of other factors reflecting the intellectual-historical upheavals of the Age of Enlightenment: contemporary musical aesthetics, socio-cultural developments (middle-class concert business), and fundamental religious-historical dynamics that led to a distancing from dogma and to a change in piety practice.
»Manch eine*r liegt, morgens noch trunken, im Rosengarten« – Rekonstruktionen osmanischer Musikgeschichte in Gesangstextsammlungen
Authors: Haug Judith I.
Published: October 2020

In Ottoman music culture, song text collections (güfte mecmūʿaları) play a crucial role in transmitting vocal repertoire. They employ paratext which supplies information about modal and rhythmic organisation as well as genre, composer and author attribution. In combination with oral tradition continuing until the present day, this method was understood as sufficient in the prevalent absence of notation until roughly the mid-19th century. Using the example of “Kimi mestāne seḥer yār ile gülşende yatur” by Rūḥī-yi Baġdādī, a poem set to music at least three times since around the mid-17th century which is still part of the repertoire today, we explore possibilities of evaluating güfte mecmūʿaları as source material for the historiography of Ottoman art music.
Marcel Prawy und das erste Broadway-Musical im Österreich der Nachkriegszeit
Authors: Koch Renate
Published: October 2020

Marcel Prawy, born in Vienna, graduated in law. In 1936, the couple Kiepura/Eggerth engaged him as private assistant. Two years later Jan Kiepura helped him to emigrate to New York. In 1943, after his employment ended, Prawy joined the US Army. Finally he returned as an elite soldier to Vienna and began his pioneering work for ‘Broadway Musicals’. In 1955, he was appointed dramaturge at the ‘Wiener Volksoper’. One year later in February, Kiss Me, Kate was performed in two Austrian theatres. The Viennese version was produced by Prawy himself and staged by Heinz Rosen. In Graz André Diehl directed the orchestration by conductor Rudolf Bibl on the basis of a piano score. Prawy relied on a mixture of Austrian theatre luminaries and American actors. In the Volksoper 183 performances took place – Graz had only 16. The reviews for the Viennese premiere reaffirmed the cheers. The criticism of the Graz production did not receive the same attention as Prawy’s production did.
Die weinende Jury. »Geschlechtslose« Tränen bei globalen Musik-Castingshows?
Authors: Kohl Marie-Anne
Published: October 2020

Tears are flowing. Whether Yvonne Catterfeld, Kazim as-Sahir, Unati Msenga-na, Liu Huan, Simon Cowell or Lira – they are all part of a jury of global music casting show formats such as The Voice, Idol or Got Talent and show their tears in front of the camera, seemingly ashamed and yet completely uninhibited. Their tears flow in reaction to ‘particularly soulful’ music titles or to the candidates’ tragic personal stories, paired with the ‘right’ song selection. The display of great emotions is an essential element of reality TV formats. With Sara Ahmed, they can be understood in the sense of an ‘affective economy’ as an effect of their circulation, their staging as a specific ‘emotional style’ of dealing with emotions (Eva Illouz). The circulation of affects in casting shows is a global one, since the formats, developed in Europe, have produced local versions in over 60 countries worldwide. Emotions play an important role in the successful localization of the formats and define a complex area of conflict between a sensitization to socio-cultural characteristics and the ‘reproduction of culturalistic concepts’ (Laura Sūna) or clichés. In European cultural history, tears have developed a special significance as guarantors of the authenticity of empathy (Sigrid Weigel), and are generally associated with femininity, however at the same time have been film-historically recoded as ‘gender-neutral’ (Renate Möhrmann). Keeping in mind that all these casting show formats have been exported from Europe, these observations are of special interest, especially since one can see men and women crying equally in the Arabic, German or South African versions of e. g. The Voice. This article questions the concurrence of musical performance, display of tears, gender performance and the translocal dramaturgy of music casting shows.
»Strafspiel« und satirische Stilmittel in musikdramatischen Gattungen des frühen 18. Jahrhunderts
Authors: Marcaletti Livio
Published: October 2020

The tendency of today’s historiography to portray early 18th-century Italian opera as a dichotomy between opera seria and opera buffa takes too little account of the existence of genera mixta. However, contemporary composers and authors sometimes referred to a tripartiton. In his treatise Der vollkommene Capellmeister (1739), Johann Mattheson distinguishes between tragedy, comedy and satire. His description of the melodies from a satirical opera is limited to the statement that they are “ridiculous, poseuristic and prickly”. This definition can be applied to the analysis of dramatic vocal works with the help of Gérard Genette’s category of “burlesque travesty” which describes the stylistic degradation of a tragic-heroic subject as a satirical function. This stylistic mixture is achieved by the use of specific musical devices, which are shown in this article on the basis of case studies on music by Francesco Bartolomeo Conti, Johann Sebastian Bach and Georg Friedrich Händel.
Lied versus Oper – Pole musikalischer Gattungen bei Oscar Bie
Authors: Ringendahl Elisa
Published: October 2020

A comparison of Oscar Bie’s monographies Die Oper and Das deutsche Lied shows that opera and ‘Lied’ are two extremes in Bie’s understanding of musical genres. While opera according to Bie is an “impossible work of art” which arises from countless contradictions, the low-conflict ‘Lied’ forms an opposite pole. Bie’s perception influences the way he deals with the two genres in writing: while opera is suitable for an adequate feuilleton, ‘Lied’ is not. Bie’s comparison gives him the possibility to break with established patterns of genres. It becomes apparent that for him opera takes on a special role in that it represents the culmination of the basic features of music. As a critic, Bie demands utmost congruence between object and written representation. Writing about music means to be an artist who deals with the same work of art but in another medium.
Musik mit dem Radio hören: Über den Begriff der musikalischen Aufführung
Authors: Zorn Magdalena
Published: October 2020

This article focuses on the phenomenon of listening to music via radio transmission. In an examination of linguistic findings and media archaeological observations, the specific performance characteristics of mediatized music are worked out using the example of a radio broadcast of a Beethoven symphony. The music-aesthetic and sociological essay “The Radio Symphony: An Experiment in Theory” (1941), written by Theodor W. Adorno during his stay in New York, is subjected to a re-reading. Although Adorno showed the full scope of his cultural conservatism in this essay, his thoughts nevertheless exemplify a function of technically mediated music reception that seems to be constitutive for the concept of musical performance as a whole.
Inhibitory Effects of Antifungal Drugs on Biofilm Producing Aspergillus spp. Recovered from Drinking Water System

Aims: Biofilms formed in drinking water distribution systems serve as a continuous source of fungal infections. Biofilms are thick aggregates of adherent microorganisms including pathogenic species of fungi. Respiratory diseases and skin allergy reactions are caused by drinking water containing biofilm forming fungus and bacteria. One of the main causes of nosocomial infections and respiratory diseases in hospitals is due to the fungal biofilm formation in machines, catheters and other surgical instruments. There are some antifungal drugs which are used to control biofilm formation to minimize the infection rate. Methodology and results: The present study was conducted to isolate and identify Aspergillus species which are the main fungal spp. responsible for the biofilm formation in drinking water and to check their antifungal susceptibility against antifungal drugs. The isolated fungal samples from drinking water were cultivated on Potato dextrose agar for the isolation of Aspergillus species. Isolated Aspergillus species were identified on the basis of cultural, morphological and microscopic examination. Then in-vitro ability of biofilm produced by isolated Aspergillus species was estimated using microtitre plate method and quantification by crystal violet assay. Antifungal susceptibility testing against isolated fungal spp. was done by antifungal drug Amphotericin B. Results: From results, it is concluded that drinking water of labs, hospitals and common water chillers were more prevelant by Aspergillus species whereas water from reverse osmosis plants showed negative results. From microtitre plate method and crystal violet assay, it was concluded that Aspergillus spp. are Susceptible against Amphotericin B drug as compared to miconazole. Keywords: Aspergillus spp; Biofilm; Drinking water; Disk diffusion method; Amphotericin B
Additive Color Mixing of Semi-Transparent Laminated Tandem Type Polymer Light-Emitting Diodes
Authors: Morimoto Masahiro , Ozawa Yuya , Naka Shigeki , Okada Hiroyuki
Published: October 2020

Polymer light-emitting diodes (PLEDs) are generally fabricated using the wet process. Although it is difficult to stack multiple layers by the wet process, it is compatible with the lamination process that can be used to fabricate multi-layer tandem type devices. We fabricate tandem type PLEDs composed of two transparent substrates using the lamination process. Stacked red and green PLEDs exhibit additive color mixed emission resulting in orange emission. By careful selection of materials, similar emission is observed from both substrates of the semi-transparent tandem PLEDs because the over-layer does not absorb the emission from the under-layer.
Early Neolithic Pottery of the Multilayered Site Ust-Khaita (Southern Angara Region)
Authors:   Irkutsk State University, Saveliev N. A. , Ulanov I. V. ,   Irkutsk State University
Published: October 2020

This article presents the largest collection of Early Neolithic pottery in the Southern Angara region, which was found at the Ust-Khaita site. The problem of the correlation between burials and settlements of the Neolithic in the South of Central Siberia has not been resolved yet. Therefore, there are two periodization schemes, which are based on the materials of burials and settlements. The second scheme is based on pottery, which is the main source for the study of historical and cultural processes in the Neolithic. That is why, it is important to study large collections of ceramics. One of the largest was found at the Ust-Khaita site. It is located in the Belaya river’s middle flow. The excavations were carried out in 2000 and the results have not been fully published. In this article we described the pottery of the Early Neolithic and carried out a technical and technological analysis. The Early Neolithic vessels are found in layers 5a and 5 and are divided into two groups. The first group is ceramics with cord impressions. It is called the Khaita type (38 vessels). The second group is ceramics with net impressions (32 vessels). We have identified three types of ornamentation for Khaita pottery. The bottom of the vessel was made on base forms, the role of which was played by other pots. The authors obtained new confirmation of the use of ornamented fragments or small vessels as anvils for knocking out the walls of Khaita pots. In particular, we found that the knolls on the inner surface are traces of the use of fragments decorated with pricks like anvils. Net-impressed ceramics show a variety of mesh weaving and mesh printing methods. The facts of use as an anvil for knocking out fragments of Net and Khaita ceramics have been diagnosed. For the first time, a net decor was found at the junction, as well as nail impressions as an element of the ornament. Also there are the vessels in the collection that show a mixture of cord and net pottery features. This fact and the closeness in the morphology and technology of the two groups of ceramics testify to the close interaction of the carriers of these two pottery traditions and their cultural affinity. The location of the Early Neolithic ceramics under conditions of clear stratigraphy made it possible to date these complexes by the 14C method. As a result, their age is determined in the range of ~8400–6900 cal BP and it puts Ust-Khaita in a number of objects with the earliest dates for these ceramics in the Southern Angara region and the Cis-Baikal.
Results and Prospects of Research of Slab Graves of Cis-Olkhon (Coast of Lake Baikal)

The article is devoted to summing up the results of the study of slab graves in the Cis-Olkhon (the western coast of Baikal from Cape Elokhin to the Bolshaya Buguldeika River, including Olkhon Island). The existence of this culture refers to the Late Bronze – Early Iron Ages. The Cis-Olkhon and the Kuda steppes of the Baikal region are the northern border of the spread of this culture, the center of which is Mongolia and Transbaikalia. The work is based on literary and archival information on the slab graves of the region for all years of study, including our own field works. The history of the collecting materials and their interpretation from the end of the 19th century to the present day is considered. On the territory of the Cis-Olkhon, 43 sites of slab graves were recorded, of which 19 were excavated in different years (47 graves were found). A list of archaeological objects was determined, their cartographic binding was carried out, information on burial practices, grave goods the presence of anthropological and faunal remains and their definitions for all published objects were collected. The analysis of the relationship between the location of burial grounds and the physic-geographical conditions and landscapes of the Cis-Olkhon was carried out. It was found that all of them are confined to steppe areas suitable for cattle breeding that was the basis of the economic activity of the carriers of this culture. All currently available radiocarbon dates for slab graves have been generalized and analyzed. The influence of the reservoir effect on the dating results obtained from human bones was revealed. At present, AMS radiocarbon dates (20 determinations) performed according to modern techniques are correct. The dating results demonstrate the chronological range of cultural distribution in the Cis-Olkhon within the limits of 2778–1998 cal BP (corrected date). An assessment of all available data on slab graves in the Cis-Olkhon revealed a high potential and prospects for their further research. The necessity for the publication of all discovered burials and a wider introduction of methods of natural sciences (anthropological, zooarchaeological, radiocarbon dating, taking into account the influence of the effect of a water reservoir, diet, etc.) in the study of these materials was noted.
Khongodors: Problems of Origin of the Ethnonym and Formation of the Buryat Tribe
Authors:   East-Siberian State Institute of Culture, Bolkhosoev S. B.
Published: October 2020

The article is devoted to the consideration of the ethnonym origins and the formation of the Buryat tribe “Khongodor”. The study of this topic is one of the current problems, the resolution of which can clarify some unknown aspects of the ethnogenesis and ethnic history of the Buryats, as well as the origin of its separate local component. This article presents a new version, according to which the emergence of the ethnonym of the Buryat tribe was associated with ethnopolitical processes that took place in the early Buryat community. And this ethnopolitical community was dominated by Bulagats. This was indicated by the etymological analysis of the ethnonym “Khongodor” and the names of the main genera. These names indicate the dependent position of the bearers of these names on the leading Association. It explains the formation of the generic kernel Khongodors presented by these two groups. Its ethnic basis is based on the Oirat component, known in the Buryat tradition as “Segenut” or “Olet”. This ethnic element is also characterized by the presence of a Turkic admixture. This proves the Mongol origin of the Khongodor core. It was part of the early inhabitants of the Western Baikal region and did not represent a tribal formation during the period of Bulagat domination. Changes in the ethnic history of the Khongodors occur in the second half of the 17th century. This aspect is connected with the external factors – the military and political influence of the Russian state and the migration of Mongolian groups to the territory of Buryatia. All this had an impact on the internal structure of the Buryat community. The study proves that due to the Russian influence, which caused a violation of established ties within the Buryat community, conditions for the formation of an ethnolocal Khongodor association arose. From the Khongodors and Mongol groups (Khotogouts, Torgouts, Zungars), the Russian authorities organized an administrative formation that gave rise to the tribal formation. In the process of living together on the same administrative territory, they become aware of unity and form a common genealogical relationship. They take a common name and form a tribe. All this happened in the 18–19th centuries.
Lower and Middle Paleolithic of Kazakhstan: Morphological, Technological and Typological Aspect of the Study of Bifacial Artefacts on the example of Handaxes from the Aral Sea Region and the Mugalzhar Mountains
Authors:   University of Perpignan Via Domitia, Osipova E. A. ,   European Centre for Prehistoric Research,   A. Kh. Margulan Institute of Archaeology, Artyukhova O. A. ,   A. Kh. Margulan Institute of Archaeology, Mamirov T. B. ,   A. Kh. Margulan Institute of Archaeology

Situated at the crossroads of Europe and Asia, actual Kazakhstan represents a strong scientific interest in understanding of the early human migrations “Out-of-Africa” to the Far East. During the whole Pleistocene, the arid conditions of this geographic area hindered the sediment accumulative deposits and the formation of stratified Paleolithic sites. Only studies of lithic industries from the sites with a surface cultural horizon seem possible. These analyses are based on a deflation degree of artefacts and on their technological and typological study followed by a comparison with other lithic collections from stratified and dated sites from surrounding grounds. This paper presents the morphological, technological and typological study of handaxes from the surface sites discovered in the Mugalzhar mountains and in the Aral Sea region. The goal of the study is to reconstitute the operational procedure (chaîne opératoire) in handaxe manufacture with the following comparison study between the handaxe samples. The lithic collection (20 artifacts) is housed at the A. Kh. Margulan Institute of Archaeology (Almaty, Kazakhstan). The analysis of data allows seeing the stark technological difference in the handaxe manufacture from the Mugalzhary mountains and from the Aral Sea region sites. As regards the typological analysis, the great majority of these handaxes from the Mugalzhary sites are characterized by fairly elongated and massive forms. Only on is of discoidal morphology and rather thin in thickness. The other are represented by one amygdaloidal, seven ovate, two lanceolate and two naviform (spear-shaped) handaxes. Any cordiform or triangular handanxes are not determined. Between the handaxes from the Aral Sea region sites, the majority is caracterised by elongated and rather thickened forms. Only one cordiform handaxe from the sample is thin. The elongated handaxes are represented by one amygdaloidal and by three lanceolate objects. It is expected that the handaxes from the Mugalzhary sites belong to more ancient period than the collection from the Aral Sea region sites. The predominance of both lanceolate handaxes and limandes is a typical dance of the Acheulean period, in particular, of its middle phase.

Lactose intolerance in human beings is the inability to digest significant amounts of
lactose due to a shortage of the lactase enzyme. Rice milk is made as an alternative milk
for people with limitation of milk consumption. The effect of (i) homogenization pressure
(10-30 MPa) and time (5-20 mins); (ii) and sterilization conditions (3-11 mins at 121.1oC)
on the quality of purple rice milk were investigated. To understand the quality of rice
milk, the Nutrition Facts was established and the percentage daily value was calculated.
The study of homogenization with pressure and time showed that the lowest creaming
index was achieved at pressure 20 MPa and duration time of 10 to 15 mins, owing to the
stable emulsions that were homogenized in the presence of additives. Sterilizing at
121.1oC for 7 mins could provide an acceptable microorganism compared to others. The
results indicated that the percentage of calories from the macronutrients in this formula
was within the AMDRs standard, with the percentage of calories ranges from 60.23, 15.26
and 24.5% of carbohydrate, protein and lipid, respectively. Furthermore, it was observed
that the chemical components of the product were not significantly different during
storage while the total microbial counts and lipid oxidation performed as peroxide value
were lower than the maximum allowed limit after four months of storage at ambient
temperature (28±2oC).
An effective feature learning approach using genetic programming with image descriptors for image classification
Authors: Bi Ying , Xue Bing , Zhang Mengjie
Published: October 2020

© 2005-2012 IEEE. Being able to extract effective features from different images is very important for image classification, but it is challenging due to high variations across images. By integrating existing well-developed feature descriptors into learning algorithms, it is possible to automatically extract informative high-level features for image classification. As a learning algorithm with a flexible representation and good global search ability, genetic programming can achieve this. In this paper, a new genetic programming-based feature learning approach is developed to automatically select and combine five existing well-developed descriptors to extract high-level features for image classification. The new approach can automatically learn various numbers of global and/or local features from different types of images. The results show that the new approach achieves significantly better classification performance in almost all the comparisons on eight data sets of varying difficulty. Further analysis reveals the effectiveness of the new approach to finding the most effective feature descriptors or combinations of them to extract discriminative features for different classification tasks.
Full-immersion virtual reality for experiential education: An exploratory user experience analysis
Authors: Schott Christian , Marshall Stephen
Published: October 2020

Experiential education is widely considered an effective pedagogy to foster learning for our rapidly changing world. Despite this, residential fieldtrips are on the decline. Recent advances in full-immersion virtual reality (VR) technology offer great potential to make situated experiential education, such as fieldtrips, more accessible to educational institutions, however, research on VR technology’s effectiveness in this context is lacking. This article documents exploratory action research which examines the effectiveness of full-immersion VR technology for experiential education by adopting a user experience (UX) analytical frame. Six university staff and five students who participated in a trial of a virtual environment developed for sustainable tourism education, discussed their user experience through semi-structured interviews. The UX lens which distinguished between three UX facets during the analysis, beyond the instrumental, emotion and affect, experiential, serves to identify research areas requiring attention and assists in the technology’s improvement prioritisation. Interviews revealed many positive perspectives thus lending support to VR technology’s suitability to foster experiential education, however, several negative experiences were also identified; principally motion sickness. The exploratory findings suggest that more research is warranted to more comprehensively examine VR technology’s capacity to foster experiential education and locate VR’s place in the education landscape.
Using in-silica Analysis and Reverse Vaccinology Approach for COVID-19 Vaccine Development
Authors: Agarwal Ajay
Published: October 2020

Background: The recent pandemic of COVID19 that has struck the world is yet to be battled by a potential cure. Countless lives have been claimed due to the existing pandemic and the societal normalcy has been damaged permanently. As a result, it becomes crucial for academic researchers in the field of bioinformatics to combat the existing pandemic. Materials and Methods: The study involved collecting the virulent strain sequence of SARS-nCoV19 for the country USA against human host through publically available bioinformatics databases. Using in-silica analysis, reverse vaccinology, and 3-D modelling, two leader proteins were identified to be potential vaccine candidates for development of a multi-epitope drug. Results: It was revealed that the two leader proteins ORF1ab MT326102 and MT326715 had the highest extinction coefficient and the lowest score on the GRAVY. Along with the given parameters, these leader proteins were highly stable and were also antigenic in nature. The two selected epitopes were then docked against their respective alleles to obtain the global energy scores, which was the lowest of all possible pairs. Conclusion: The epitopes which displayed the lowest global energy score on docking with the alleles were selected and proposed as successful and potential vaccine candidates for multi-epitope vaccine development. Doi: 10.28991/SciMedJ-2020-02-SI-9 Full Text: PDF

A descrição linguística e sua abordagem no ensino da língua espanhola
Authors: Simões Adriana Martins
Published: October 2020

The aim of this paper is to present reflections on linguistic description approach in Spanish language teaching, regarding generative (CHOMKY, 1981; 1986) and sociolinguistic (LABOV, 2008; WEINREICH; LABOV; HERZOG, 2009) theoretical perspectives. For this, we will present the initial results of the research that we are developing about the 3rd person accusative pronominal object in the Spanish variety of Madrid and Brazilian Portuguese and reflections on Spanish language teaching. The idea is that the advances in linguistic description and its approach in teaching considering those theoretical perspectives can conduct the student to reflect on Spanish operation and to understand the linguistic and social contexts that were involved in linguistic variation.
A intrínseca relação entre atitude e crença: um estudo qualitativo com alguns estudantes universitários brasileiros de Inglês
Authors: Anjos Flávius Almeida dos
Published: October 2020

This paper is about some Brazilian undergraduate students’ attitudes and beliefs. Thus, it presents some data of a qualitative study, whose objective was to verify the existence of a relationship between ‘attitude’ and ‘belief’. The data emerged from a questionnaire applied with 91 undergraduate students, from a Brazilian university, who studied English compulsorily. To support the study, some categories of analysis were elaborated: 1. Attitudes hold or integrate beliefs and 2. Beliefs emerge as a justification of an attitude. The data analysis pointed the existence of an intrinsic relationship between attitude and belief. The relevance of this study lies in the need to understand this issue even more, since as far as one is concerned, until now, only few researches have proposed to reflect on this relationship as well as the understanding of this relationship can contribute to the improvement of the teaching/learning of English.
