Authors: Nijaz Dizdarević  , Matislav Majstrović  , Srđan Žutobradić
Published: June 2023

Sažetak: U ovom je radu predstavljen problem FACTS regulacije napona i kompenzacije jalove snage u distribucijskoj mreži s priključenom vjetroelektranom. Vjetroelektrana je u izvedbi sa stalnom brzinom i konstantnom frekvencijom uz korištenje asinkronog generatora pogonjenog nereguliranom vjetroturbinom. Problem je razmatran s obzirom na kratkotrajni (10 sekundi), srednjotrajni (10 minuta) i dugotrajni (48 sati) vremenski period odziva varijabli sustava na različite promjene brzine vjetra. S obzirom na promjenjivu brzinu vjetra, vjetroelektrana injektira promjenjivi iznos djelatne i jalove snage u distribucijsku mrežu te time izlaže obližnje potrošače značajnim promjenama iznosa napona.  U konvencionalnom pristupu rješavanja problema korištene su poprečne kondenzatorske baterije smještene u čvorištu asinkronog generatora. U FACTS pristupu korišten je ''objedinjeni regulator tokova snaga'' (eng. Unified Power Flow Controller, UPFC) koji je smješten u točki priključenja vjetroelektrane na distribucijsku mrežu. Korištenje FACTS naprave predstavlja pokušaj rješavanja tehničkih pitanja vezanih uz regulaciju napona u čvorištu priključenja vjetroelektrane te uz minimiziranje razmjene jalove snage vjetroelektrane s distribucijskom mrežom.

ON THE ACCOMMODATION OF TAUTOLOGIES IN THE ABSENCE OF BACKGROUND KNOWLEDGE
Authors:   Saint Petersburg State University, Shkaruba Daria D.
Published: June 2023

In this experimental study, we aim to determine whether tautological utterances with proper names require any mutually shared background knowledge to be fully understood. We argue that such tautologies can be sufficient when used independently and thus can be accommodated even if one does not have any mutually shared assumptions with their interlocutor. The results of our survey show that the ability to accommodate a tautology depends on the existence of its referent's behavioral manifestation clues explicitly stated in a preceding piece of discourse.
GŎDAĆ OR MÓWIĆ: MODERN LANGUAGE PRACTICES OF ETHNIC SILESIANS IN POLAND
Authors:   The European University at Saint Petersburg, Vasyukov Alexander D.
Published: June 2023

This paper is focused on the linguistic situation in Upper Silesia, an ethnocultural region in Southern-Western Poland. The Silesians are a West Slavic minority group that traditionally has been regarded in Polish political and scientific discourse as an ethnographic group of Poles. Based on anthropological fieldwork, the author describes the specificity of modern linguistic processes in the region, the social prestige of Silesian and the movement for its recognition as a regional language in Poland. This research shows how the national construction and state language policy in Silesia have defined the linguistic identity and the language choice of modern Silesians.
AWARENESS OF PHILIPPINE ENGLISH: THE CASE OF UNDERGRADUATE STUDENTS
Authors:   Mindanao State University-Main Campus, Ali Mohammad Nassef D.
Published: June 2023

Although there is an increase in the number of studies on Philippine English (PE), there is very little research tackling Filipinos’ awareness of PE. This study was done to help expand the limited research on PE awareness, fill the gaps in a few related studies, and test Filipinos’ cognizance of their English variety. Specifically, this research investigated undergraduate students’ awareness of the meanings, features, and uses of PE and its relationship with their age. This study employed a quantitative approach and used an online survey form to collect data. The form consisted of Likert items on PE which were rated by the respondents according to their awareness of each statement. After surveying 216 respondents, it was found that the undergraduate students were slightly aware of the existence of a local English variety, i.e. PE. However, the data show that the respondents were moderately conscious of the other meanings, features, and uses of PE. This suggests that the students were fairly aware of PE but have slight cognizance of its legitimacy as an English variety. A similar finding can be observed in the students’ consciousness of PE features, where they showed moderate awareness of PE having its own accent, phonology, vocabulary, and grammar, but low average consciousness on the acceptability of PE lexicon and grammar. These findings reveal the respondents’ lack of recognition of PE validity, a common issue in non-native English varieties. Spearman rank correlation was used to determine the relationship between the students’ age and their level of PE awareness. With a rho of -0.07, this study claims no significant correlation between the two variables and concludes that age is not a factor influencing PE awareness. Overall, this study reveals the fair awareness of Filipino undergraduate students towards PE and their low awareness of its legitimacy. Also, as shown in the results, the cognizance of a local English variety cannot be assumed among its speakers. Thus, language awareness should be considered as a factor in World Englishes studies.
CONTEXTS OF THE USE OF THE DEFINITE ARTICLE UNDER STRESS IN DUTCH
Authors:   Institute of Linguistics of the Russian Academy of Sciences, Tereshko Ekaterina V.
Published: June 2023

In linguistics, there is a widespread belief that the article cannot be in the stressed position, because if it is in this position, we perceive it as a (short) form of the indicative pronoun. However, the materials of the Dutch language refute this statement, telling us that at least in some languages the article can take on the accent. In Dutch, this accent is often marked graphically, which makes it easier to find examples and prove their relevance. This article examines the contexts in which the accented article is used in Dutch, among which the contrastive and the emphatic contexts stand out. The study is based on a sample of corpus examples from a corpus of ≈1.5 million tokens of fiction. While examining the examples, an assumption is made about the categorical polysemy of articles.
SUBJUNCTIVE AS FUTURE TIME REFERENCE IN CLASSICAL ARMENIAN: DIFFERENCES BETWEEN AORIST AND PRESENT SUBJUNCTIVE
Authors:   Saint Petersburg State University, Arakelyan Irina A.
Published: June 2023

The study views the use of Classical Armenian subjunctive forms (aorist subjunctive and present subjunctive) as future time reference. The analysis is based on 100 contexts with subjunctive forms from the Gospel of Matthew. The results show that the distribution between two possible variants of subjunctive (one from aorist and one from present stem) is supposedly based on a number of factors. The study views the possible factors of influence on the Classical Armenian subjunctive forms from the Greek text influence to the morphology of Classical Armenian.
ORDER ICONICITY PRINCIPLE IN TEMPORAL INTERPRETATION OF RUSSIAN PERFECTIVE PARTICIPIAL AND CONVERBIAL CLAUSES
Authors:   HSE University, Prigorkina Veronika
Published: June 2023

Pragmatic factors frequently affect the interpretation of grammatical constructions, and the category of relative tense is no exception. To arrange the events on the timescale with respect to each other interlocutors may resort to the implicit content of the phrase – implicatures. The current study observed the effect of a specific pragmatic phenomenon – Order Iconicity Principle (OIP) – on the interpretation of non-finite taxis constructions in Russian: perfective past participles (prichastija) and perfective converbs (deeprichastija). According to this principle, the perceptually and statistically preferred temporal interpretation of sequential events is the one which iconically corresponds to the predicates' order of mentioning. Based on a series of self-paced reading and interpretation acceptability judgements (IAJ) experiments, I suggest that OIP applicability scope can be extended from coordinated structures with perfective verbs [Paducheva 2017; Khrakovskij 2009] and dependent temporal clauses [Clark & Clark 1968; Sasanuma & Kamio 1976; Natsopoulos et al. 1991; Jansen 2008] to nonfinite constructions. In accordance with the hypotheses, for both Russian perfective participles and converbs there was a significant OIP effect, manifested in higher acceptability rates and shorter interpretation latencies for iconic temporal interpretation even when the interpretations were not contextually or lexically supported. Due to the difference in the syntactic and discourse properties of the constructions (scale of finiteness, syntactic function, preservation of the dynamic verb semantics and category of absolute tense; [Vjal'sova 2008]; [Krapivina 2009]; [Say 2020]), a significantly smaller OIP effect was noted for participles. Results of an additional pilot study including free-interpretation of these constructions even further suggest that highly debatable posteriority interpretation in Russian non-finite clauses [Rappaport 1984; Shigurov 1991; Weiss 1995; Akimova & Kozintseva 2001; Khrakovskij 2003; Birzer 2010] to be a specific realization of OIP implicature for Russian perfective converbs and of an absolute past reference for Russian perfective past participles.
SEMANTIC ASPECT OF THE VOCABULARY DESCRIPTION OF ABBREVIATIONS
Authors:   Donetsk National University, Riazanova Valeria A.
Published: June 2023

The article deals with the problem of representing the semantic characteristics of abbreviations in specialized dictionaries of abbreviations. Using material of specialized dictionaries it has been established that the semantics of abbreviations is almost never described in dictionary entries. This is due to the idea that in order to understand the meaning of an abbreviation it is enough to indicate the collocation motivationally associated with it, i.e. to carry out the so-called decoding. The need for a full-fledged interpretation of abbreviations is conditioned by the semantic features of abbreviations as independent language units. We identify the limited scope of the use of abbreviations; idiomatic meaning of abbreviations; possibility of homonymic relations, which should be distinguished from cases of polysemy; multiple meanings of abbreviations, which may in some cases lead to multiple structural interpretation of abbreviation. The article also studies the means of realization of a multidimensional semantic and word-formation vocabulary description of abbreviations.

From 2022 March 18 to 21, NOAA Active Region (AR) 12967 was tracked simultaneously by Solar Orbiter at 0.35 au and Hinode/EIS at Earth. During this period, strong blueshifted plasma upflows were observed along a thin, dark corridor of open magnetic field originating at the AR’s leading polarity and continuing toward the southern extension of the northern polar coronal hole. A potential field source surface model shows large lateral expansion of the open magnetic field along the corridor. Squashing factor Q-maps of the large-scale topology further confirm super-radial expansion in support of the S-web theory for the slow wind. The thin corridor of upflows is identified as the source region of a slow solar wind stream characterized by ∼300 km s−1 velocities, low proton temperatures of ∼5 eV, extremely high density >100 cm−3, and a short interval of moderate Alfvénicity accompanied by switchback events. When the connectivity changes from the corridor to the eastern side of the AR, the in situ plasma parameters of the slow solar wind indicate a distinctly different source region. These observations provide strong evidence that the narrow open-field corridors, forming part of the S-web, produce some extreme properties in their associated solar wind streams.
Lack of Correlations between Cold Molecular Gas and AGN Properties in Type 1 AGNs at z ≲ 0.5
Authors: Molina Juan , Shangguan Jinyi , Wang Ran , Ho Luis C. , Bauer Franz E. , Treister Ezequiel
Published: June 2023

We present new NOrthern Extended Millimeter Array (NOEMA) observations of the CO(2–1) emission in eight of the brightest Palomar-Green quasars at z ≲ 0.5 to investigate the role of active galactic nucleus (AGN) feedback in luminous quasars detected at low redshifts. We detect CO(2–1) emission in three objects, from which we derive CO luminosities, molecular gas masses and fractions, and gas depletion times. In combination with data available in the literature, we build a total sample of 138 local type 1 AGNs with CO(2–1) measurements. We compare the AGN properties with the host galaxy molecular gas properties, considering systems nondetected in CO emission. We find that the CO luminosity does not correlate with AGN luminosity and Eddington ratio, while the molecular gas fraction is weakly correlated with Eddington ratio. The type 1 AGNs can be roughly separated into two populations in terms of infrared-to-CO luminosity ratio, with one population presenting values typically found in normal star-forming systems, while the other having lower ratio values, comparable to those measured for starbursts. We find no evidence that AGN feedback rapidly quenches star formation in type 1 AGNs. Our results may imply an underlying the role of host galaxy gravitational instabilities or the fast inflow of cold gas in triggering AGN activity.

We report the discovery of five bright, strong gravitationally lensed galaxies at 3 < z < 4: COOL J0101+2055 (z = 3.459), COOL J0104−0757 (z = 3.480), COOL J0145+1018 (z = 3.310), COOL J0516−2208 (z = 3.549), and COOL J1356+0339 (z = 3.753). These galaxies have magnitudes of r

AB < 21.81 mag and are lensed by galaxy clusters at 0.26 < z < 1. This sample nearly doubles the number of known bright lensed galaxies with extended arcs at 3 < z < 4. We characterize the lensed galaxies using ground-based grz/giy imaging and optical spectroscopy. We report model-based magnitudes and derive stellar masses, dust content, and star formation rates via stellar population synthesis modeling. Building lens models based on ground-based imaging, we estimate source magnifications ranging from ∼29 to ∼180. Combining these analyses, we derive demagnified stellar masses in the range

Future Constraints on Dark Matter with Gravitationally Lensed Fast Radio Bursts Detected by BURSTT
Authors: Ho 何建 Simon C.-C. 璋 , Hashimoto Tetsuya , Goto Tomotsugu , Lin Yu-Wei , Kim Seong Jin , Uno Yuri , Hsiao Tiger Y.-Y.
Published: June 2023

Understanding dark matter is one of the most urgent questions in modern physics. A very interesting candidate is primordial black holes (PBHs). For the mass ranges <10−16
M
⊙ and >100 M
⊙, PBHs have been ruled out. However, they are still poorly constrained in the mass range 10−16–100 M
⊙. Fast radio bursts (FRBs) are millisecond flashes of radio light of unknown origin, mostly from outside the Milky Way. Due to their short timescales, gravitationally lensed FRBs, which are yet to be detected, have been proposed as a useful probe for constraining the presence of PBHs in the mass window of <100 M
⊙. Up to now, the most successful project in finding FRBs has been CHIME. Due to its large field of view, CHIME has detected at least 600 FRBs since 2018. However, none of them is confirmed to be gravitationally lensed. Taiwan plans to build a new telescope, the Bustling Universe Radio Survey Telescope in Taiwan (BURSTT), dedicated to detecting FRBs. Its survey area will be 25 times greater than CHIME. BURSTT can localize all of these FRBs through very long baseline interferometry. We estimate the probability to find gravitationally lensed FRBs, based on the scaled redshift distribution from the latest CHIME catalog and the lensing probability function from Munõz et al. BURSTT-2048 can detect ∼24 lensed FRBs out of ∼1700 FRBs per annum. With BURSTT’s ability to detect nanosecond FRBs, we can constrain PBHs to form a part of dark matter down to 10−4

Published: June 2023

We present a new study of the Z Cam-type eclipsing cataclysmic variable AY Piscium with the aim of determining the fundamental parameters of the system and the structure of the accretion flow therein. We use time-resolved photometric observations supplemented by spectroscopy in the standstill, to which we applied our light-curve modeling techniques and the Doppler tomography method, to update system parameters. We found that the system has a massive white dwarf M
WD = 0.90(4) M
☉, a mass ratio q = 0.50(3), and the effective temperature of a secondary T
2 = 4100(50) K. The system inclination is i = 74.°8(7). The orbital period of the system P

Notorhinus floresi sp. nov. gen. nov.: The first records of Siphonophorida in Chile and Siphonorhinidae in South America (Colobognatha)
Authors: Moritz Leif , Parra-Gómez Antonio
Published: June 2023

The millipede family Siphonorhinidae (order Siphonophorida) shows a scattered distribution in South Africa, Madagascar, India, Southeast Asia, and North America. So far, the family is unknown from South America, while species of Siphonophoridae, the second family of the order, are relatively abundant on the continent. However, not a single Siphonophorida is known from Chile. Here we describe the monotypic genus Notorhinusgen. nov. with N. floresisp. nov. and record a second Notorhinus (undescribed) species, as first records of the order Siphonophorida in Chile and of the family Siphonorhinidae in South America. Notorhinusgen. nov. is distinct from the remaining Siphonorhinidae by the arrangement of the sensilla basiconica on the antennae and other somatic and sexual characters. However, it shows close morphological affinities to the North American genus IllacmeCook and Loomis 1928. In the Americas Siphonorhinidae were previously only known from California (USA), where they inhabit subterranean micro-habitats. The Chilean species was found under a piece of decaying wood in a small patch of fragmented native forest. Thus, the group shows a disjunct antitropical distribution in America at ca. 37° North and 38° South. They might be the relict of a once greater distribution, which persisted in these areas due to similar climatic conditions.
Basal Metabolic Rate Related to Metabolic and Clinical Features in Male Patients With First-Episode Psychosis
Authors: Algul Ayhan , Gündoğmuş İbrahim
Published: June 2023

We investigated basal metabolic rate (BMR) in male patients with drug-naïve first-episode psychosis (FEP) in order to explore the hypothesis that a reduced BMR plays a role in severity of illness. The study was conducted with a total of 59 drug-naïve FEP patients, 41 of whom were severe and 18 nonsevere. BMR was measured using Body-Gem Analyzer 3.0 Metabolism Measurement Device indirect calorimetry. At the same time, the clinical characteristics and laboratory tests of the participants were measured. The patients were divided into two groups as severe and nonsevere according to the Clinical Global Impression-Severity. At the end of measurement, the BMR was compared between patients with severe and nonsevere illness. BMR of patients with severe illness was found to be statistically significantly lower than BMR of patients with nonsevere illness. Another finding of the study is that in patients with severe FEP we can expect BMR values below the cut-offvalue of 1,830 kcal/day. The study provides evidence that BMR is reduced with severity of illness in drug-naïve FEP patients.

Therapeutic Profile of Cannabidiol in the Broad Symptomatology of Autism Spectrum Disorder: Evidence From Basic Science to Clinical Approaches
Authors: Pedrazzi João Francisco Cordeiro , Hassib Lucas , Ferreira Frederico R.
Published: June 2023

Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders whose symptoms include impaired communication and social interaction, stereotypies, and varying levels of intellectual disability. Together with these symptoms are co-occurring psychiatric or neurological conditions, often with hyperactivity and attention disorders, anxiety, depression, and epilepsy. So far, no effective treatment for ASD is available, possibly because its neurobiological basis and heterogeneous nature are not clearly understood. Clinical and preclinical trials support the involvement of the endocannabinoid system in the patho-physiology of ASD. Cannabidiol (CBD), the main nonpsychotomimetic compound of the cannabis plant, interacts with the endocannabinoid system and has significant therapeutic potential in treating several psychiatric disorders and manifestations of ASD. After this article, readers are expected to have a broad understanding of current scientific evidence and perspectives on the use of CBD in cases of ASD.

Published: June 2023

This article will summarize the current knowledge and scientific evidence regarding cannabidiol as a possible pharmacological tool for anxiety disorders. Although the use of this substance in medical practice is gaining momentum, gaps can still be found in the current knowledge regarding its molecular targets, drug-to-drug interactions, efficacy in different populations, adequate dosage, duration of treatment, and correct formulation. Moreover, current evidence is still preliminary, lacking robust, blinded, and placebo-controlled clinical trials in many areas of investigation. After reading this article, readers should have a thorough understanding of the current scientific evidence regarding the use of CBD as an anxiolytic drug.

Offshore floating photovoltaic system energy returns assessment—A life cycle energy analysis-based perspective
Authors: CHEN Ching-Feng
Published: June 2023

Researchers have long regarded photovoltaics (PV) as a poor energy return (ER) compared to fossil fuels. Although the latter's energy-return-on-investment (EROI), like oil, coal, and gas, are above 25:1 at the primary, they are about 6:1 at the final stage. Following the technology creation, it is essential to investigate whether the solar module technology innovation affects the ER. Much literature delivers the ERs of fossil fuels and PV. However, it does not address the life cycle analysis or life cycle energy analysis (LCEA) assessments. This paper, employing time-series and LCEA analyses, performs an ER evaluation of the 181-MWp global most extensive offshore floating PV (OFPV) in a 30-year life cycle at Changhua Coastal Industrial Park, Taiwan. The results show that the energy payback time (EPBT) is about one year. The EROI is about 29.8, which is superior or complies with the upper limits of previous studies under the same insolation. The approach proposed in this study should help future PV stations' ER analysis and clarify whether the innovation benefits from improving the system's performance. The results also assist in investors' decision-making regarding deploying PV projects in the future.
Satellite road extraction method based on RFDNet neural network
Authors: Liu Weichi , Dong Gaifang , Zou Mingxin
Published: June 2023

The road network system is the core foundation of a city. Extracting road information from remote sensing images has become an important research direction in the current traffic information industry. The efficient residual factorized convolutional neural network (ERFNet) is a residual convolutional neural network with good application value in the field of biological information, but it has a weak effect on urban road network extraction. To solve this problem, we developed a road network extraction method for remote sensing images by using an improved ERFNet network. First, the design of the network structure is based on an ERFNet; we added the DoubleConv module and increased the number of dilated convolution operations to build the road network extraction model. Second, in the training process, the strategy of dynamically setting the learning rate is adopted and combined with batch normalization and dropout methods to avoid overfitting and enhance the generalization ability of the model. Finally, the morphological filtering method is used to eliminate the image noise, and the ultimate extraction result of the road network is obtained. The experimental results show that the method proposed in this paper has an average F1 score of 93.37% for five test images, which is superior to the ERFNet (91.31%) and U-net (87.34%). The average value of IoU is 77.35%, which is also better than ERFNet (71.08%) and U-net (65.64%).

Published: June 2023

In this article, we introduce the concept of generalized rational type $ F $ -contractions on relation theoretic m-metric spaces (denoted as $ F_{R}^{m} $-contractions, where $ R $ is a binary relation) and some related fixed point theorems are provided. Then, we achieve some fixed point results for cyclic rational type $ F_{R}^{m} $- generalized contraction mappings. Moreover, we state some illustrative numerically examples to show our results are true and meaningful. As an application, we discuss a positive definite solution of a nonlinear matrix equation of the form $ \Lambda = S+\sum\limits_{i = 1}^{\mu }Q_{i}^{\ast }\Xi \left(\Lambda \right) Q_{i} $.
La dialectique entre activités informelles et action de l’État dans la construction territoriale des grands espaces : le cas de l’orpaillage dans l’intérieur de la Guyane française
Authors: Le Tourneau François-Michel , Noucher Matthieu
Published: June 2023

Les grands espaces, ou régions faiblement peuplées, se distinguent par une série de caractéristiques spécifiques et notamment par un contrôle incomplet de la part des États. Cela ouvre des brèches pour l’exercice de pratiques qui, si elles sont ou illégales ou à la limite de la légalité, apportent des ressources économiques, des connaissances sur les territoires concernés et participent finalement à la domination, voire à la conquête des zones concernées par les États. Bien qu’invisibles ou réprimées, ces activités informelles influencent donc, directement ou indirectement, la construction officielle, symbolique et matérielle du territoire. Cet article analyse la pratique de l’orpaillage en Guyane selon cette perspective. En analysant le jeu dialectique entre contrôle formel du territoire et exploitation informelle des ressources, il met en relief la contribution des activités informelles à l’exploration, à la formation des frontières et à la gouvernance de l’intérieur de ce territoire français d’Amérique du sud.
La responsabilité morale de la fiction
Authors: BENOIST Jocelyn
Published: June 2023

Les philosophes abordent souvent la fiction suivant un angle d’attaque ontologique : comme si la question première était de savoir si les entités auxquelles réfère le discours fictionnel existent ou non. Cette perspective ontologique a l’inconvénient de détourner l’attention du discours fictionnel lui-même en tant qu’il peut jouer un certain rôle dans nos vies. Platon, au livre III de la République, s’interroge quant au fait de savoir s’il faut raconter des histoires et lesquelles. Dans ce contexte, vient sur le devant de la scène la question de l’auctorialité et de la responsabilité, assumée ou non, du discours fictionnel. L’interrogation platonicienne peut paraître décalée au goût des contemporains : essentiellement moralisatrice. La question est cependant de savoir s’il est possible de soustraire la fiction à toute problématique morale, ou si un tel questionnement, quelle que soit la réponse qu’on lui donne, ne fait pas essentiellement partie de l’appréhension de la fiction en tant que discours.
Product-service-system design thinking for port healthcare: a case study with container lashers in the port of Antwerp
Authors: Zelck Sander , Dewit Ivo , Scataglini Sofia , Denteneer Lenie , Verwulgen Stijn
Published: June 2023

The port of Antwerp executes its container lashing with specialized dockworker crews called container lashers. These container lashers train in the port training center, OCHA, in order to execute container lashing safely and efficiently. Container lashing is considered labor intensive. Due to the future trends within maritime transportation, the interest in optimized ergonomic training provided for dockworkers rises. A User-Centered Design approach is implemented to gather insights to build a Product-service-system (PSS) solution in a multidisciplinary research context. In order to develop a meaningful PSS, clinical and cultural insights are required. This paper presents the research framework of Design Inclusive Research (DIR) to collect cultural insights from container lashers. Subsequentially, it elaborates on the different stages of DIR to the extent of defining and executing the design tools. For this study, Cultural Probes and user journey maps, in combination with in-depth interviews, are applied to gather, synthesize, and present the information to stakeholders in a validation workshop. The proposed design tools and framework delivered an array of contextual information, leading to a broader understanding of the container lashers’ culture and generating impactful solutions.
Application of Neutrosophic Sets to Assessment of Student Learning Skills
Authors: Voskoglou Michael G.
Published: June 2023

Assessment is a very important component of education, because it helps the instructor to determine student mistakes and to improve student performance by reforming his/her teaching plans. Various assessment methods under fuzzy conditions (with qualitative grades) are presented in this Chapter, developed in earlier author's works. The first method, termed as the Rectangular Fuzzy Assessment Model (RFAM), is based on the Center of Gravity (COG) defuzzification technique. The outcomes of RFAM, which evaluates a group's qualitative performance, are compared to those of the classical calculation of the Grade Point Average(GPA) index. A method using triangular fuzzy numbers as assessment tools is also presented and it is proved to be equivalent with an analogous method using closed real intervals (grey numbers) as tools. These two methods, which are equivalent to each other, evaluate a group's mean performance. Further, a hybrid assessment approach is developed using grey numbers, neutrosophic sets and soft sets as tools, which is applied for assessing student learning skills.
Application of Neutrosophic Soft Set to Assess Academic Performance of Students Using Bloom's Taxonomy

A key aspect of human cognition is learning, a universal process that all humans undergo. In order to learn or improve one's knowledge and abilities, it integrates influences from the cognitive, emotional, and environmental spheres. There are vast amounts of studies and a wide range of hypotheses that attempt to describe the workings of the learning process. The purpose was to gain an objective understanding of how individuals learn and then build pedagogical strategies appropriately. In this chapter, neutrosophic soft sets, a novel mathematical technique for dealing with uncertainty, are utilized to measure student learning capabilities with Blooms taxonomy. Generations of educators have used Bloom's taxonomy as a framework for instruction and evaluation, and they continue to do so today, because of the taxonomy's emphasis on the need of engaging students at all levels of cognitive development. In addition, a practical example from the teaching process would be given to show how it might be used in practice.
Introducing Vagueness in the Mathematical Curriculum of Secondary Education

Vagueness is a quality that is usually ignored or considered a deficiency for any system, in the broad sense of the word. However, vagueness seems to be a fundamental property of our world and so systems that are precisely defined are rather the exception than the norm (e.g., in most cases we ignore some details that are supposed not to affect the overall behavior of a system). Because of this “attitude”, vagueness and its mathematics have not been introduced in secondary education; the goal is to change this. Therefore, the authors prepared a series of lessons that have been taught to middle school pupils and recorded the input we got from them. The authors report the structure of the lessons as well as the input received and the prospects of actually introducing vagueness in the mathematical curriculum of secondary education in Greece.
QSVN Soft Sets and Their Applications in Student Classification
Authors: Sinha Kalyan , Majumdar Pinaki
Published: June 2023

For a learner, grades are very important. However, our modern educational system cannot provide correct grades to a student. In the current grading system, overall educational activities are not measured perfectly. Different letter grades are given to students in different subjects. The class rank is determined by considering average grade of these subjects. All these well-known methods of grading are not errorless. Thus, modern grading systems cannot be a proper reflection of student knowledge. In recent years, several authors have studied problems regarding educational measurement, particularly student assessments and grading. But most of the new methods are based on statistical techniques. Here, the authors have introduced Quadripartitioned single valued neutrosophic soft set (QSVNSS) for the first time. The authors have studied some set theoretic properties of QSVNSS. Also, several distance measures on QSVNSS are introduced. Based on the distance measures on QSVNSS, this chapter proposes some similarity measures on QSVNSS. Finally, these similarity measures are applied to a MADM real life problem.
A Case Study of Disaster Risk Reduction in Schools for the Blind in Thailand
Authors: Wongsuriyanan Chayanee , Tsuchida Shoji
Published: June 2023

In Thailand, 9% of people with disabilities are visually impaired (VI). VI children are vulnerable when disasters occur. This study investigates risk situations and disaster risk reduction (DRR) methods in VI schools to identify present and potential ways that students can be provided skills. An interview was administered in two schools to schoolteachers and administrators. Content analysis was used to analyze qualitative data based on core keywords. DRR for daily risk exposure and fires is the priority. Concerns over VI students are based on the difficulty in orientation. Support is considered crucial for student safety. Supervisory means to limit risk among the VI is uncertain in times of disaster. Students are capable of learning about DRR and, combined with assistive techniques, can limit their risk. DRR policies in VI schools are primarily reactive. Uncomplicated risk awareness information and training could foster an appropriate approach to bringing self-efficacy to deal with risk.

This study explored social media (SM) usage amongst young adults. Participants (N = 750) completed an online survey about their usage of/relationship with SM and the sacrifices they would make to remain on SM. Almost half of participants reported checking SM 9+ times/day and more than three-quarters spent 1+ hour/day on SM. SM addiction scores averaged 17.5/30 (SD = 5.08). Regression analyses revealed that number of SM checks/day (p < 0.05), time/day spent on SM (p < 0.01), and SM addiction (p < 0.001) all predicted increases in the number of trade-offs participants were willing to make, F(6,733) = 21.941, p < 0.001, R2 = 0.390. These results act to both confirm existing literature, while also highlighting the specific compromises young adults would make to maintain their SM access. Future health efforts should aim to promote awareness of these psychological and social issues.

Published: June 2023

Despite the positive impact of maker education on student learning, challenges towards its implementation in formal school settings still exist. There is limited research on maker education in teacher education programs and a lack of knowledge on how to integrate it into the mathematics classroom. To address these issues, the following research questions were examined: What is the nature of the productive design features of maker education for teacher candidates? What are the benefits and challenges of these opportunities for teacher candidates learning to teach mathematics? The methods used were a case study interlinked with design-based research. A total of 114 teacher candidates participated in the study. The research findings have implications for educators who design/implement maker education curricula into STEM courses. For educators and researchers, the maker education opportunities from this study contribute to further re-imagining learning competencies, pedagogy, and resources in teaching mathematics and other STEM disciplines.

Published: June 2023

E-learning is an online educational system that uses electronic and technology tools and the internet. To facilitate the acquisition of knowledge, students can consult materials and interact directly with lecturers via e-learning educational systems. The method for developing an intelligent querying system for e-learning is suggested in this research. The knowledge base of the system is structured using the knowledge model combining an ontology and the two-layer knowledge graph, called Rela-KG model. The searching problems for knowledge content are studied and solved. The technique is applied to create an intelligent querying system on the course of Database Foundation in Information Technology (IT) at the university. This technique attempts to assist students in reviewing lectures and better comprehending course material through independent study. The experimental results indicate that it would be anticipated to support student access to online learning resources.

Published: June 2023

Objective: This study was conducted to investigate the relationship between the angle of the cervical curve and the presence of chronic neck pain. Material and Methods: Case control study was conducted among 363 patients, (females 76.9%), who had neck pain (>3 months) and 349 individuals, (females 58.5%), with no neck pain, aged 20-69 years. Angle of the cervical curve was measured in lateral x-rays of cervical spine using AutoCAD 2014 and cross checked by two Consultant Radiologists. Angle of the cervical curve was categorized as 35°-45°-normal lordosis, <35°-hypolordosis and >45°-hyperlordosis. Percentages of each category were calculated.Results: Among the patients with chronic neck pain, 44.9% (n=163) had hypolordosis, 49% (n=178) had hyperlordosis and 6.1% (n=22) had the normal lordosis. Among the individuals with no neck pain, the majority (80.8%, n=282) had the normal lordosis, 12.3% (n=43) had hypolordosis and 6.9% (n=24) had hyperlordosis. Chi square test showed a statistically significant association between neck pain and the angle of cervical curve (p=0.001). According to Cramer’s V (0.615) there was a strong association between the two variables. For purposes of analysis both hypolordosis or hyperlordosis were categorized as atypical angle. When compared to individuals with a normal lordosis, those with an atypical angle have a 3.3 times risk of having neck pain.Conclusion: Hypolordosis or hyperlordosis, atypical angle of the cervical curve contribute to chronic neck pain.
Laparoscopic Colon Resection
Authors: AlSaleh Fatma M. , Hussein Bassem Abou , Kaiyasah Hadiel , AlMarzouqi Omar
Published: June 2023

Background:

Laparoscopic surgery has a well-documented role in colon resection with improved postoperative outcomes even in low-volume centers. Recently, we have integrated minimally invasive laparoscopic resection, followed by the enhanced recovery after surgery (ERAS) protocol, to improve postoperative outcomes in our hospital.

Objectives:

To review our experience of laparoscopic colonic resection with the ERAS protocol and compare our outcomes with those in the literature.

Design:

Observational retrospective.

Setting:

Governmental tertiary hospital.

Materials (Patients) and Methods:

Data of patients over 18 years of age who had undergone laparoscopic colonic resection between January 2016 and December 2021 were retrospectively obtained from medical records. Patients with trauma-related injuries were excluded. The variables collected included patient demographics, disease information, operative and postoperative data, and histopathological reports. Data were compared with similar published studies and landmark trials.

Sample Size:

92 patients.

Main Outcome Measures:

Rates of conversion to open procedure, number of lymph nodes harvested, hospital length of stay, percentage of positive margins, 30-day morbidity, and 30-day mortality.

Results:

During the study period, 92 patients (59% men) underwent laparoscopic colon resections, of which eight (8.6%) required an open procedure. The average operative time was 233 minutes, and the average intraoperative blood loss was 78 mL. Intraoperative complications occurred in four cases with no postoperative sequelae. The median length of hospital stay was 5 days. Malignant specimens revealed 100% disease-free margins with an average of 22 lymph nodes harvested. The postoperative 30-day morbidity, mortality, and histopathological results were comparable with landmark trials.

Conclusion:

As a new technique in a low-volume center, laparoscopic colon resection was challenging. Despite the presence of an experienced laparoscopic surgeon, extensive training was required to safely complete the procedure within a reasonable operative time with a successful outcome. Furthermore, the implementation of the ERAS protocol was difficult; however, the team mastered it after the first few cases. This study showed that both efficacy and safety can be achieved in laparoscopic colon resections in low-volume centers. Moreover, the ERAS protocols can be implemented; however, their implementation will require additional training, which may lead to better outcomes.

Limitations:

The lack of general surgery wards in a busy tertiary trauma center meant that patients with variable wound contamination would share the same unit.

Conflict of Interest Statement:

None.
