Система комплексного оцінювання якості програмного забезпечення
Authors: Грицюк Ю. І. 
Published: July 2022

Розроблено систему комплексного оцінювання якості програмного забезпечення (ПЗ), яка дає змогу визначити стан його якості на кожному ієрархічному рівні системи управління з урахуванням вартості розроблення, а також надає можливість встановити потенційні витрати для переходу показників якості ПЗ з одного стану в інший. З'ясовано, що якість ПЗ – багатопланове поняття, яке можна виразити адекватно тільки деякою структурованою системою характеристик та атрибутів, яку прийнято називати моделлю якості програмного продукту. Для оцінювання якості ПЗ було використано комплекс критеріїв, які максимально його характеризують насамперед стосовно функціональних можливостей і варіантів використання. Встановлено, що модель якості – головний атрибут комплексної системи оцінювання ПЗ, позаяк визначає, які характеристики якості продукту потрібно враховувати при оцінюванні його властивостей. Рівень, за якого ПЗ задовольняє заявлені та опосередковані потреби різних зацікавлених сторін і, в такий спосіб, забезпечує його значущість для них є саме тими властивостями, що відображено в моделі якості, яка класифікує їх на характеристики та підхарактеристики. Розроблено метод відбору напружених варіантів стану системи якості ПЗ за вхідними критеріями чи агрегованими показниками, що дає змогу визначити поточний стан якості ПЗ за відповідним агрегованим показником з урахуванням вартості його розроблення. Розроблено метод вибору оптимального варіанту системи комплексного оцінювання якості ПЗ з множини допустимих альтернатив, яка враховує ієрархічну структуру критеріїв і агрегованих показників його якості на кожному ієрархічному рівні. Встановлено, що задача вибору оптимального варіанту системи оцінювання якості ПЗ з урахуванням таких критеріїв, як зручність супроводу продукту та його портативності, безпеки продукту та його сумісності, а також надійності роботи продукту, зручності використання та функціональної придатності належить до задач багатокритеріальної оптимізації. Наведено приклад реалізації системи комплексного оцінювання якості ПЗ, що дає змогу зрозуміти сутність зазначеного методу вибору оптимального її варіанту, а також методу відбору напружених варіантів стану системи якості ПЗ за двома критеріями чи агрегованими показниками.

The demographic data & patient characteristics in surgical unit-I and surgical unit-II in the hospital were enrolled in the study. In the study, a total number of 240 prescriptions were analyzed during the study period which includes 92 male and 148 female patients. Drug utilization can be defined as the marketing, distribution, prescription and use of drugs in a society, considering its consequences, either medical, social, and economic. The present study was performed to evaluate utilization of antimicrobial agents in surgical units at a tertiary care teaching hospital. During the 6 months period, we collected 240 prescriptions with antimicrobial agents from both surgical I and surgical II units. The data collected were analysed and summarised accordingly. A study of utilization of antimicrobial agents in surgical units at a Jaybharath hospital, Nellore was conducted. The most frequently used antimicrobial monotherapy agents were ceftriaxone and ciprofloxacin. The most frequently used antimicrobial combinations were amoxicillin + clavulanic acid and cefoperazone+salbactum. Sensitivity pattern of antimicrobial agents in surgical departments will help the physician to select the proper drug of choice
Fermi-LAT Detection of a GeV Afterglow from a Compact Stellar Merger

Published: July 2022

Abstract
It is usually thought that long-duration gamma-ray bursts (GRBs) are associated with massive star core collapse, whereas short-duration GRBs are associated with mergers of compact stellar binaries. The discovery of a kilonova associated with a nearby (350 Mpc) long-duration GRB—GRB 211211A, however, indicates that the progenitor of this long-duration GRB is a compact object merger. Here we report the Fermi-LAT detection of gamma-ray (>100 MeV) afterglow emission from GRB 211211A, which lasts ∼20,000 s after the burst, the longest event for conventional short-duration GRBs ever detected. We suggest that this gamma-ray emission results from afterglow synchrotron emission. The soft spectrum of GeV emission may arise from a limited maximum synchrotron energy of only a few hundreds of MeV at ∼20,000 s. The usually long duration of the GeV emission could be due to the proximity of this GRB and the long deceleration time of the GRB jet that is expanding in a low-density circumburst medium, consistent with the compact stellar merger scenario.

Abstract
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) 19-beam tracking observational mode, high-sensitivity and high-velocity-resolution H i spectral lines have been observed toward the high-mass star-forming region G176.51+00.20. This is a pilot study searching for H i narrow-line self-absorption (HINSA) toward high-mass star-forming regions where bipolar molecular outflows have been detected. This work is confined to the central seven beams of FAST. Two HINSA components are detected in all seven beams, which correspond to a strong CO emission region (SCER; with a velocity of ∼−18 km s−1) and a weak CO emission region (WCER; with a velocity of ∼−3 km s−1). The SCER detected in Beam 3 is probably more suitably classified as a WCER. In the SCER, the HINSA is probably associated with the molecular material traced by the CO. The fractional abundance of HINSA ranges from ∼1.1 × 10−3 to ∼2.6 × 10−2. Moreover, the abundance of HINSA in Beam 1 is lower than that in the surrounding beams (i.e., Beams 2 and 4–7). This possible ring could be caused by the ionization of H i or the relatively rapid conversion from H i to H2 in the higher-density inner region. In the WCER (including Beam 3 in the SCER), the HINSA is probably not associated with CO clouds, but with CO-dark or CO-faint gas.
The Nature of Low-albedo Small Bodies from 3 μm Spectroscopy: One Group that Formed within the Ammonia Snow Line and One that Formed beyond It

Abstract
We present evidence, via a large survey of 191 new spectra along with previously published spectra, of a divide in the 3 μm spectral properties of the low-albedo asteroid population. One group (“sharp types,” or STs, with band centers <3 μm) has a spectral shape consistent with carbonaceous chondrite meteorites, while the other group (“not sharp types,” or NSTs, with bands centered >3 μm) is not represented in the meteorite literature but is as abundant as the STs among large objects. Both groups are present in most low-albedo asteroid taxonomic classes, and, except in limited cases, taxonomic classifications based on 0.5–2.5 μm data alone cannot predict whether an asteroid is an ST or NST. Statistical tests show that the STs and NSTs differ in average band depth, semimajor axis, and perihelion at confidence levels ≥98% while not showing significant differences in albedo. We also show that many NSTs have a 3 μm absorption band shape like comet 67P and likely represent an important small-body composition throughout the solar system. A simple explanation for the origin of these groups is formation on opposite sides of the ammonia snow line, with the NST group accreting H2O and NH3 and the ST group only accreting H2O, with subsequent thermal and chemical evolution resulting in the minerals seen today. Such an explanation is consistent with recent dynamical modeling of planetesimal formation and delivery and suggests that much more outer solar system material was delivered to the main asteroid belt than would be thought based on the number of D-class asteroids found today.

Published: July 2022

Java is the most populous island in the world. This high population and the extensive economic activities have significantly reduced the forest areas of the Island and have greatly increased the pressure on its plant diversity. Compared to those with a wide distribution, endemic plants with a narrow geographic range are more vulnerable to anthropogenic threats and environmental changes. As species lists are essential for knowledge of species diversity in areas with strong anthropogenic pressure, here we present a dataset of endemic plants of Java Island. The initial species list was manually extracted from the Plant of the World Online (POWO). Each species on the list was then confirmed for its endemism by checking its current distribution using peer-reviewed publications, online plant databases and herbarium specimen images stored on the Global Biodiversity Information Facility (GBIF). The dataset contains 652 species in 279 genera and 85 families. The family with the highest number of endemic species is Orchidaceae (142 species), followed by Rubiaceae (57 species), Acanthaceae (40 species), Apocynaceae (35 species) and Lauraceae (29 species). The growth form of the species is mostly trees (22.6%), followed by herbs (19.2%), epiphytes (16%), shrubs (12.4%), vines (11%) and geophytes (9.4%). Most of the species (89.7%) have not yet been assessed for their conservation status according to the IUCN Red List Categories and Criteria. There are only 55 species (8.3%) that have been conserved within ex situ collections. Furthermore, most of the species (79.8%) are not listed on the CITES appendices and there are only four species (0.6%) protected by national law.
Our contribution provides the first online list of accepted scientific names of Javan endemic plants species, together with all their synonyms. New to the dataset are: i) provision of local names of the species (if available), ii) the classification of species under eleven growth forms (tree, shrub, herb, annual, graminoid, geophyte, fern, vines, hydrophyte, parasite and epiphyte), iii) assignation of the extinction risk of species according to the IUCN Red List, iv) ex situ collection status of species and information on the protection status of the species according to (v) CITES and (vi) the national law of Indonesia.

Training of future STEAM teachers: Comparison between primary degree students and secondary master's degree students
Authors: Ortega Torres Enric 
Published: July 2022

In recent years, the presence of the acronym STEAM has been growing in the educational field. All around the world we are faced with a growing demand for professional STEM skills, however, who has the responsibility to train future STEAM teachers? In this article, we explain the results of an investigation with university students pursuing a degree in primary education and Master’s degree students in secondary education, with technology speciality, participating in a seminar about STEAM projects design in two consecutive academic calendar years (18/19 and 19/20). We analyse the responses to a questionnaire which was specifically designed to discover their knowledge about STEAM and the predisposition towards its extended study with a set of semi-structured interviews to delve into the causes of the responses. Previous knowledge about the meaning of STEM and the predisposition of pre-service teachers towards the future design of projects based on the STEAM disciplines are compared. The results show significant differences between the previous knowledge and the perceptions of the teachers from both specializations: primary and secondary level. The results also confirm the low levels of prior knowledge with a slight tendency towards improvement when two consecutive courses are compared. The findings emphasize the need to integrate STEAM teacher training into official curricula.

Prostor posoške skupnosti iz starejše železne dobe (8.–4. st. pr. n. št.), znane kot svetolucijska halštatska kulturna skupina, zaznamujejo različne geomorfološke značilnosti in naravne danosti. Najstarejše jedro stalne poselitve se je izoblikovalo ob naravnih poteh, ki vodijo ob Nadiži in Soči iz Furlanske nižine oz. iz zaledja severnega Jadrana v alpski visokogorski svet.
O stalni poselitvi na začetku železne dobe pričajo predvsem grobišča, medtem ko je v naseljih zaradi skromne raziskanosti starejše obdobje (8.–6. st. pr. n. št.) slabše prepoznavno. Grobovi iz starejših faz kažejo na manjše lokalne skupnosti, grobni pridatki pa ne izražajo večjih družbenih razlik. Družbeno razslojevanje je zaznavno v mlajših fazah (6. do 4. st. pr. n. št.), ko se ob prevladujočem pokopu sežganih ostankov v preprosto grobno jamo, pokrito s kamnito ploščo, poja- vijo tudi maloštevilni žarni grobovi v obliki kamnite skrinje in z bogatejšimi pridatki. V mlajšem obdobju je naselje na Mostu na Soči doseglo največji obseg in se razvilo v glavno regionalno središče z zgodnjeurbanimi značilnostmi. V 6. in 5. st. pr. n. št. je opazna tudi ekspanzija te skupnosti, zrasla so nova manjša naselja. Večinoma so bila deloma utrjena, v neutrjenih bi lahko videli naselja drugega ranga. V 4. st. pr. n. št. so sledili pretresi in spremembe, ki so privedli do dezintegracije skupnosti. Prebivalstvo se je iz starih aglomeracij umaknilo v stranske doline in bolj hribovite predele, v grobnih in daritvenih obredjih pa je v znatnejši meri prisotno orožje.
A INFÂNCIA E A EDUCAÇÃO A PARTIR DA OBRA DE MODO ADDISCENDI DE GILBERTO DE TOURNAI NO SÉCULO XIII
Authors: Silva Andrei Roberto da , Moraes Juliana de Mello 
Published: July 2022

Em 1263, Gilberto de Tournai (1209-1284) finalizou a obra De modo addiscendi, um tratado pedagógico destinado a Jean Dampierre. Esse texto foi produzido em Paris no século XIII, momento de crescimento das instituições educacionais. O autor da obra foi um frade franciscano, mestre de teologia na Universidade de Paris e conselheiro do rei Luís IX da França. Na obra, Gilberto orienta os mestres e familiares a educar as crianças para que tenham uma formação espiritual e intelectual. A partir desta obra, o objetivo é analisar as representações da infância e da sua educação no período. Para tanto, utilizamos o conceito de representações de Roger Chartier (2002) e Jacques Verger (1999) para abordar o ensino medieval. Esta pesquisa é qualitativa e documental. O estudo indica que as representações forjadas por Tournai inscrevem a infância como um período de formação, na qual os esforços do mestre deveriam fomentar a submissão e a obediência, propiciando o desenvolvimento da sabedoria. A análise da obra de Tournai corrobora a perspectiva de que a educação se conectava aos modos de pensar e caracterizar a infância, bem como da importância da Igreja católica para a constituição e difusão de representações sobre a infância na época.
A conjecture strengthening the Zariski dense orbit problem for birational maps of dynamical degree one
Authors: Bell Jason , Ghioca Dragos 
Published: July 2022

AbstractWe formulate a strengthening of the Zariski dense orbit conjecture for birational maps of dynamical degree one. So, given a quasiprojective variety X defined over an algebraically closed field K of characteristic
$0$
, endowed with a birational self-map
$\phi $
of dynamical degree
$1$
, we expect that either there exists a nonconstant rational function
$f:X\dashrightarrow \mathbb {P} ^1$
such that
$f\circ \phi =f$
, or there exists a proper subvariety
$Y\subset X$
with the property that, for any invariant proper subvariety
$Z\subset X$
, we have that
$Z\subseteq Y$
. We prove our conjecture for automorphisms
$\phi $
of dynamical degree
$1$
of semiabelian varieties X. Moreover, we prove a related result for regular dominant self-maps
$\phi $
of semiabelian varieties X: assuming that
$\phi $
does not preserve a nonconstant rational function, we have that the dynamical degree of
$\phi $
is larger than
$1$
if and only if the union of all
$\phi $
-invariant proper subvarieties of X is Zariski dense. We give applications of our results to representation-theoretic questions about twisted homogeneous coordinate rings associated with abelian varieties.

Published: July 2022

Evaluation of medicinal plants for their antidiabetic activities has increased considerably around the world as well as in Algeria. Olea europaea, commonly called Zeytoune, is traditionally used by Tlemcen population in Algeria, for treating diabetes mellitus.
In this work, we evaluate the capacity of O. europaea leaves crude extracts to inhibit in vitro α-amylase activity.
The qualitative phytochemical screening carried out on O. europaea leaves extracts showed the presence of tannins, sterols and triterpenes, saponins, flavonoids and terpenoids. A quantitative analysis of the crude extracts showed significant levels of total polyphenols and flavonoids in hydroacetonic extract, with an amount of 802.57 ± 0.001 mg GAE/ g and 359 ± 0.002 mg CE/ g, respectively. In vitro tests carried out on the inhibitory of α-amylase activity, revealed an inhibitory effects, specifically with hydroacetonic extract in a concentration-dependent manner, with an IC50 value of 0.27 ± 0.02 mg/mL. These findings reveals that O. europaea leaves extracts could represent an interesting source of bioactive compounds and allow to the development of new antidiabetic agents.
As temáticas físico-naturais nas provas do ENADE dos cursos de licenciatura em Geografia
Authors: Ribeiro Lygia de Oliveira , Oliveira Jully Gabriela Retzlaf de 
Published: July 2022

A Geografia é uma ciência voltada ao estudo da produção do espaço a partir da interação entre sociedade e natureza. Em específico, a Geografia Física volta-se para o estudo das dinâmicas da natureza na paisagem em conjunto com as condições antropológicas. Contudo, as temáticas físico-naturais na Geografia são corriqueiramente abordadas de maneira estanque, sem inserir a sociedade em suas análises. Diante desse contexto, este trabalho tem por objetivo analisar a abordagem dos temas físico-naturais nas provas do Exame Nacional de Desempenho dos Estudantes (ENADE) aplicadas aos cursos de Licenciatura em Geografia. Para tanto, procedeu-se à pesquisa bibliográfica relacionada ao ensino dos componentes físico-naturais na Geografia Escolar; elaboração de uma ficha de avaliação para as provas do ENADE; levantamento das questões do componente específico das provas aplicadas aos cursos de Licenciatura em Geografia; e, por fim, análise da abordagem das questões relacionadas aos temas físico-naturais da Geografia nas provas em questão. Em síntese, verificou-se que a maior parte das questões analisadas do ENADE apresentam abordagem contemporânea da Geografia Física, pois, além das dinâmicas naturais, destacam a ação antrópica como modificadora dos elementos naturais e geradora de impactos socioambientais.

The physical-natural themes in the ENADE exams Geography degree courses
Abstract
Geography is a science targeted to the study of production of space from the interaction between the society and the nature. In a specific way, the Physical Geography focuses on the study of nature’s dynamics in the landscape with the anthropological condictions. However, the physical-natural themes in Geography are usually approached in a watertight manner, not including the society in its analyses. Within this context, this work aims to analyse the physical-natural themes approaching in the tests of the Exame Nacional de Desempenho dos Estudantes (ENADE) directed to Geography degree courses. For this purpose, a bibliographic research related to the teaching of physical-natural componentes in School Geography have been done; elaboration of evaluation file for the tests of ENADE; survey of the questions about the specific component applied to Geography degree courses and finally, the approaching analyse about the questions related to the physical-natural themes of Geography in the mentioned tests. In summary, it was found that the majority of the analised questions of ENADE present contemporary approach of Physical Geography, because in addition to the natural dynamics, the anthropic action is highlighted as a modifier of natural elements and a generator of socio-environmental impacts.
