In conclusion, the declarations, charters, appeals for the development of the school physical education and sport referred to in the paper impact positively the state policies of the countries in Europe.
A nemszteroid gyulladáscsökkentő szerek reumatológiai alkalmazása a cardiovascularis prevenció tükrében
Authors: Sütő Gábor
Published: January 2022

Összefoglaló. A reumatológiai betegségek gyakoribb cardiovascularis
megbetegedéssel és halálozással járnak. Ennek oka a veleszületett fogékonyság, a
tradicionális cardiovascularis rizikófaktorok, a folyamatos gyulladásos háttér
és a mozgásszegénység, amelyek mellett a gyógyszerszedés sem elhanyagolható
tényező. A nemszteroid gyulladáscsökkentő szerek egyik legismertebb mellékhatása
a cardiovascularis megbetegedés és halálozás előfordulásának fokozódása, amely
az egyes készítmények esetében eltérő mértékű. Ezt a különbséget sokáig a
ciklooxigenáz-1 és -2 enzim eltérő mértékű gátlásával magyarázták. A prospektív
összetett cardiovascularis végpontú vizsgálatok azonban nem igazoltak jelentős
különbséget a ciklooxigenáz-1 és -2 gátlása között. A megfelelő
gyógyszerválasztás a klinikai vizsgálatok tapasztalatai alapján történik,
figyelembe véve a beteg és a betegség adottságain túl az adott készítmény
tulajdonságait. A jelenlegi ismeretek alapján a cardiovascularis rizikó
szempontjából a kis és közepes adagú ibuprofén vagy dexibuprofén, valamint
naproxén tűnik előnyösnek, habár ez utóbbi esetében gastrointestinalis
szövődményekkel kell számolni. Orv Hetil. 2022; 163(3): 93–97.

Summary. Rheumatological diseases are associated with more common
cardiovascular morbidity and mortality. This is due to inherited susceptibility,
traditional cardiovascular risk factors, persistent inflammatory background, and
lack of exercise. Medication is also not a negligible factor. One of the best
known side effects of non-steroidal anti-inflammatory drugs is the increased
incidence of cardiovascular morbidity and mortality, which varies among the
different treatments. This difference has long been explained by different
levels of inhibition of cyclooxygenase-1 and -2 enzymes. However, prospective
composite cardiovascular endpoint studies did not demonstrate a significant
difference between cyclooxygenase-1 and -2 inhibition. The choice of the
appropriate drug is based on the experience of clinical trials, taking into
account the characteristics of the particular product in addition to the patient
and the characteristics of the disease. Based on the current knowledge, low and
moderate doses of ibuprofen or dexibuprofen and naproxen appear to be beneficial
for cardiovascular risk, although gastrointestinal complications are to be
expected in the latter. Orv Hetil. 2022; 163(3): 93–97.
Mathematical Treatment Model of Lassa Fever
Authors: Chinedu Obasi , Godwin Mbah C.E. , Ndidiamaka Didigwu , Paschal Offor
Published: January 2022

We present and explore a novel mathematical treatment model of the epidemiology of Lassa Fever (LF). The model is a system of nonlinear ordinary differential equation model for rodent and human population. We analyzed the model to find the stability of the disease-free equilibrium and
test which model parameters affect this stability most significantly. The purpose of this paper is to investigate the impact of treatment on the control of LF. The analysis revealed that treatment rate of humans will have a positive impact in reducing the burden of LF in the population. Our
model predicts that treatment control can reduce the population level transmission by up to 12% alone without existing interventions. Therefore, treatment has significant effect on LF transmission, but it may not be able to eliminate the disease unless a multiple control strategy is adopted.
Finally, some numerical simulations were carried out to support our theoretical results.
A Multi-Phase Closed Pipelines Simulation Approach for Transportation of Heavy Oil with Openfoam in HPC
Authors: Banerjee Alomoy , Barman Shambhunath
Published: January 2022

Transportation of heavy crude oil through closed pipelines is a challenging issue both in offshore and in land oil transportation. The scope of the present paper deals with the computational modelling of two phase extra heavy crude oil & water flow in OpenFOAM. In order to validate
the flow model the pressure variation along the length of the channel are investigated, which shows the typical plot of two roughly constant pressure lines at different levels connected by a sharp change of pressure at the interface of two fluids. The validated flow model, aims at optimizing
the kinematic viscosity of the multiphase flow, by regulating the flow velocity of the components, such that there is minimum viscous heat loss and hence minimum pump power consumption from the horizontal centrifugal pumping system. Using the OpenFOAM(Open Source Field Operation & Manipulation)
software, which is free opensource software, developed in 2004, under GNU general public license, paraview has been used here as post processing tool. Multiphase flow simulation is done using the k-ɛ turbulence model in HPC of kanchenjungha cluster, NIT Sikkim, India.

The Puppet and the Puppet-Master in Ancient Greece: Fragments of an Art Form
Authors: Skotheim Mali Annika
Published: January 2022

Drawing on literary, epigraphical, and archaeological material, this article addresses the interrelation of the performance context, physical form, and aesthetic of ancient Greek puppetry. Puppeteers performed in a variety of contexts, which included processions and public theaters. During religious festivals, they were hired to supplement competitions in drama and music. I classify ancient Greek puppetry into two main types: the phallic puppets used in religious processions in the Eastern Mediterranean, and small-scale puppetry, which was performed in theaters and possibly also in private contexts. I contend that puppetry was not universally considered an insignificant art but was, rather, an important part of the performance culture of the ancient Mediterranean world. The inclusion of puppetry in religious festivals suggests a positive relationship with this art; reactions to puppetry, from laughter to thauma (wonder), align with the aims of the festivals which hosted such performances.
Recent update on epidural blood patch
Authors: Shin Hwa Yong
Published: January 2022

Epidural blood patch (EBP) is the injection of autologous blood into the epidural space with the intent of sealing off a dural tear and stopping the leakage of cerebrospinal fluid (CSF). EBP may cause an increase in intracranial pressure (ICP) due to the mass effect of the injected blood volume, causing CSF from the spinal compartment to enter the intracranial compartment. EBP is usually considered in the management of moderate to severe headache (HA) attributed to low CSF pressure, such as post-dural puncture HA (PDPH), CSF fistula HA, and HA attributed to spontaneous intracranial hypotension (SIH) that does not respond to conservative management. However, prophylactic administration of EBP after accidental dural puncture can hardly be substantiated at present. EBP is generally safe but may rarely be associated with serious complications. Therefore, it should be carefully planned and performed under C-arm fluoroscopic guidance. Although many studies on PDPH and SIH have been conducted until recently, only few reviews have summarized the effectiveness of EBP from the perspective of a pain physician. This article reviews the current literature on the indication, contraindication, procedural consideration, post-procedural management, outcomes, and complications of EBP and the considerations for EBP in patients with COVID-19.

Published: January 2022

ABSTRACT BACKGROUND: South African data on paediatric patients with renal trauma that are usually managed conservatively is scarce. This study aimed to review a 7-year experience of paediatric renal trauma and management METHODS: A retrospective review of all paediatric admissions with renal injury was conducted in the Department of Paediatric Surgery, University of the Witwatersrand, between 1 January 2012 and 31 December 2018. Data from medical records reviewed included patient age, gender, mechanism of injury, severity of injury, management and length of hospital stay RESULTS: Thirty-one patients with renal injuries were identified, of which 30 had complete data. Of these cases, 26/30 (87%) sustained blunt renal injuries and 4/30 (13%) were penetrating. The median age at presentation was 6 years, and 60% were females. Three patients had isolated renal injuries, and 23 had concomitant injuries including hepatic (9), thoracic (8), splenic (5), head (4), facial (3) and ureteric (1). Twenty-three patients were managed non-operatively. Two required renal exploration with resultant nephrectomies and one haemodynamically unstable patient died preoperatively. Four patients required operative intervention for concomitant injuries with no renal exploration. Two patients required ureteric stenting. The median length of hospital stay was 7 days (Range: 4-11 days, IQR 7 days CONCLUSION: Renal injuries in haemodynamically stable patients should be managed non-operatively. A 93% renal preservation rate was achieved in this cohort of patients with nephrectomy performed only in haemodynamically unstable patients with Grade V injuries, in keeping with international norms Keywords: paediatric, renal injuries, conservative management, South Africa
Surgery in South Africa - challenges and barriers
Authors: Naidu P , mazza I Butti
Published: January 2022

ABSTRACT BACKGROUND: Sustaining a surgical career can be challenging and there are numerous barriers to pursuing a career in surgery. These barriers and challenges are well reported in international literature, but there is a lack of knowledge on how this affects surgeons in South Africa. This study aimed to determine the barriers and challenges that South African surgeons face in their training and careers METHODS: A 15-item questionnaire was designed and distributed via the Research Electronic Database Capturing software from 1 February-3 April 2020. Data were analysed in Stata 15 SE. All responses were anonymised RESULTS: One hundred and twenty-nine participants responded to the questionnaire, 33 (26%) of whom were female. The majority were specialist surgeons (n = 87; 71%). One hundred and eleven participants (90%) reported they did not regret pursuing surgery. Barriers to pursuing surgery included limited personal time (n = 98; 76%), heavy surgical workload (n = 92; 71%), and difficulty taking leave of absence (n = 64; 50%), limited postgraduate training (n = 34; 26%), and verbal discouragement (n = 22; 17%). Challenges included difficulty maintaining work-life balance (n = 74; 56%), racial discrimination (n = 29; 23%) and gender discrimination (n = 15; 12%). Fifty-three per cent of participants experienced burnout CONCLUSION: Despite high career satisfaction, South African surgeons face numerous barriers to pursuing and challenges in sustaining a career in surgery and often experience burnout. These barriers and challenges disproportionately affect female surgeons and can be mitigated through formalised mentorship programmes, flexible work schedules, funding for postgraduate training, and training in diversity and discrimination Keywords: surgery, training, challenges, barriers
An analysis of paediatric snakebites in north-eastern South Africa
Authors: Buitendag JJP , Variawa S , Wood D , Oosthuizen G
Published: January 2022

ABSTRACT BACKGROUND: Snakebites are an underappreciated health concern in middle- and lower-income countries. The lack of national data vastly impacts funding for this health crisis, as well as strategies for treatment and prevention. Children are particularly vulnerable to snakebite and data in this group is limited METHODS: This study included paediatric patients, aged 13 years old or younger, admitted to Ngwelezana Tertiary Hospital, Department of Surgery with a snakebite or snakebite related complication, from 1 September 2008 to 31 December 2013. Data captured included demographics, time of presentation, syndromic symptoms, blood results and patient management RESULTS: A total of 274 patients were included in this study. The median age at presentation was 8 years, with approximately 70% of the patients aged between 6 and 13 years, with a male predominance (56%). The median time of presentation after sustaining a snakebite was 7 hours (interquartile range 4-13 hours). The majority of patients (71%) presented with cytotoxic manifestations. A total of 53 patients received antivenom of whom 25% suffered adverse reactions. Fifty-six patients underwent one or more procedures on their affected limbs. Three patients required admission to the intensive care unit; all were part of the cytotoxic group and received antivenom. There were no recorded mortalities CONCLUSION: The majority of snakebites are cytotoxic in nature. One-fifth of the paediatric population require antivenom and one-fifth require a surgical procedure post envenomation. Adverse effects post antivenom use are common but manageable. Prevention programmes are needed to help reduce this burden of disease and a nationwide snakebite registry is long overdue Keywords: paediatric, snakebite, antivenom
Mentorship during undergraduate surgical training: comparing perceptions of medical students and faculty at two institutions in South Africa and Sweden
Authors: Scott AJ , Drevin G , Pavlovic L , Nilsson M , Krige JEJ , Jonas E
Published: January 2022

ABSTRACT BACKGROUND: Having a mentor during undergraduate surgical training has been shown to positively influence medical students by increasing interest in surgery, improving confidence, and assisting in career planning. This study aimed to evaluate and compare medical student and faculty perceptions of mentorship during undergraduate surgical training and compare results between two teaching institutions in South Africa and Sweden METHODS: An electronic, online questionnaire was anonymously distributed to medical students and general surgical faculty at the University of Cape Town (UCT), South Africa, and Karolinska Institutet (KI), Stockholm, Sweden. The questionnaire consisted of multiple choice, true or false, and five-point Likert scale questions, exploring perceptions of mentorship and role models, as well as rating the most important mentor characteristics RESULTS: Approximately one third (34.2%) of students stated they had a mentor during their surgical training, with significant differences found between student cohorts (p < 0.001). The 'registrar' was most commonly reported as the best role model for medical students by faculty from both UCT (50.0%) and KI (69.4%), as well as UCT students (36.6%). Students rated the following mentor qualities significantly higher compared to faculty: student encouragement (p = 0.037), adequate supervision (p = 0.007), setting of fair expectations (p = 0.002), and teaching skills (p = 0.010 CONCLUSION: With significant differences existing in the perceptions of medical students and faculty regarding mentorship and role models during undergraduate surgical training in both South African and Swedish institutions, reconciling and harmonising these differences will be crucial in fostering constructive mentoring relationships Keywords: mentorship, role model, perception, surgical education
Factors affecting bacteriology of hand sepsis in South Africa
Authors: van der Vyver M , Maderee A
Published: January 2022

ABSTRACT BACKGROUND: Hand sepsis is a common cause of morbidity. The study was conducted in the KwaZulu-Natal province of South Africa, investigating the bacteriological profile and aetiology of hand sepsis, aiming at optimising empiric antibiotic therapy METHODS: This is a descriptive study of 120 patients who presented to the plastic surgery department of Inkosi Albert Luthuli Central Hospital with hand sepsis, from January 2017 to April 2019, that required surgical drainage. Data recorded included: aetiology of sepsis, underlying comorbidities, length of hospital stay, and outcome. A pus swab was taken during surgical drainage for microscopy, culture and sensitivity (MCS) analysis. The relationship between clinical factors and microbiological findings was analysed RESULTS: The predominant bacterial strains cultured from infected patients, excluding methicillin-resistant Staphylococcus aureus, were Staphylococcus aureus (80.8%) and Streptococcus spp. (20.0%), mostly due to spontaneous onset infection (58.3%). Cultures of the more problematic Streptococcus spp. were more frequently associated in patients with diabetes mellitus (60.0%), penetrating trauma (41.9%), or blunt trauma (31.3%). The diabetes group in isolation had the longest median hospital stay of 8 (5-15) days, the most need for multiple procedures (60.0%), amputations (30.0%), and skin grafts (20.0%). The most effective antimicrobial drug particularly in mixed cultures was amoxicillin-clavulanic acid CONCLUSION: Staphylococcus aureus infection was the most common. Streptococcus spp. occurred more frequently in patients with traumatic injury and diabetes mellitus. The latter required further surgical procedures and an increased hospital stay. Amoxicillin-clavulanic acid is the preferred empiric antimicrobial agent Keywords: hand sepsis, bacteriology, optimising empiric antibiotic therapy
Sport during the COVID-19 bio-bubble: Wellness and opinions in South African elite football
Authors: Bahdur Khatija , Pillay Lervasen , Dell’oca Duane
Published: January 2022

Background: COVID-19 imposed challenges on professional sport, with restrictions leading to the delay in the completion of the South African Premier Soccer League (PSL). Creating a biologically safe environment (BSE) provided a solution enabling the 2019/2020 season to be completed.
Objectives: Evaluating the impact that the BSE had on player wellness and what coping mechanisms were used in the BSE.
Methods: A questionnaire was distributed to PSL teams on the final weekend in the BSE. It consisted of three validated psychology questionnaires. An additional section focused on the impact and coping strategies during the PSL’s BSE.
Results: A total of 37 completed questionnaires were analysed. General anxiety (4.7±4.2) and depression levels (4.8±3.9) were at an overall low. The health of the players, as well as separation from and concerns about family, were the greatest contributors to anxiety. Electronic communication with family and friends, social interactions with others in the BSE and time spent on self-reflection were important coping mechanisms for players. As time progressed, they adapted to the BSE.
Conclusion: The BSE did not have a negative impact on the anxiety and depression levels of the respondents, with a variety of coping mechanisms key helping them adapt in the BSE.
Liefde en refleksiewe denke: Die vroeë Hegel oor die lotgevalle van die moderne mens
Authors: Duvenage P
Published: January 2022

In hierdie artikel val die fokus op hoe Georg Friedrich Wilhelm Hegel se vroeë denke en vroeë teologiese geskrifte die tema van die historiese lotgevalle van die moderne mens in die moderne wêreld hanteer. Meer spesifiek fokus die artikel op Hegel se begrip van die liefde soos hy dit in sy essay "Die Gees van die Christendom en sy lotgevalle"2 (1797-99) weergee, en op die epistemologiese, eties-politiese, ontologiese en krities-historiese implikasies daarvan. Hierteenoor word begrippe soos refleksiewe denke, eiendom en abstrakte reg in 'n sekere vroeëre dialektiese verhouding by Hegel in spel gebring. Die bydrae bestaan basies uit vier dele. Eerstens word, ter wille van die leser, 'n bondige biografiese skets van Hegel gegee. Tweedens word Hegel se vroeë teologiese geskrifte oor die verhouding van die moderne mens en sy diepste bronne, wat gedurende sy jare in Tübingen en Bern geskryf is, bondig gerekonstrueer. Dit bied derdens die agtergrond waarteen hierdie denkmotiewe by wyse van 'n fokus op sy belangrike essay "Die Gees van die Christendom en sy lotgevalle", uit sy Frankfurtse periode (1798-1799), verdiep word. Hierdie bespreking, waarin Hegel se argument in 'n aantal stappe gerekonstrueer word, vorm die kern van die bydrae. Laastens word aangetoon hoe die denkmotiewe in hierdie belangrike vroeë essay in Hegel se latere werke weerklank vind.
'n Fenomenologie van rassisme: Hegeliaanse (wan)erkenning en die struktuur van koloniale bewussyn
Authors: Villet C
Published: January 2022

Hierdie artikel neem Hegel se weergawe van die mislukking van wedersydse erkenning (dus wanerkenning) krities onder die loep met spesifieke fokus op die meester-slaaf-dialektiek. Hegel gee daarmee sy analise van 'n soort bewussynsontwikkeling wat lei tot vervreemde selfbewussyn in sowel die self as die ander (subjek en objek). Die proses wat hierdie soort bewussyn begrond, gee myns insiens 'n fenomenologiese beskrywing en verduideliking van die kognitiewe wortels van rassisme en geweld soos wat dit gemanifesteer word in 'n sogenaamde moderne koloniale mentaliteit (beide in die koloniale en die postkoloniale konteks). Dit bied met ander woorde 'n uiteensetting van hoe rassisme vorm aanneem in die selfbewussyn. Die moontlike wegbeweeg van rassisme na wedersydse erkenning word ondersoek met die doel om te sien hoe wanerkenning hanteer kan word (in die selfbewussyn). Dit word gedoen aan die hand van 'n model van Hegel se bewussynsteorie, wat verskillende soorte intersubjektiewe erkenning in breë trekke uiteensit. Die fokus van hierdie model is die wisselwerking tussen die dinglike en begripsaspekte van Hegeliaanse erkenning in die interaksie van die self (as subjek) met die ander. Hopelik kan hierdie model help om begrip te bevorder van hoe selferkenning, wanerkenning en wedersydse erkenning gepaard gaan met verskillende vorme van bewussyn. Teen die agtergrond van 'n koloniale bewussyn het wanerkenning en wedersydse erkenning 'n beduidende uitwerking op menslike verhoudinge. Fanon het dit verder belig met sy fokus op die rol van ras in die dialektiek en erkenning.
"Geen vlerke stut meer ...": Geselekteerde gedigte in Krog se mede-wete gelees as outobiografiese postsekulêre laatwerk
Authors: Taljard M
Published: January 2022

In Antjie Krog se bundel mede-wete verskyn 'n aantal gedigte waarin die ek-spreker se soeke na 'n nuwe soort spiritualiteit verwoord word en waarin die implisiete versugting na die eenheid van alle dinge voorkom. Die doel van hierdie artikel is om 'n teoretiese konsep aan die hand te doen waarvolgens die spirituele aspekte in hierdie bundel bespreek kan word. Teorieë oor outobiografie as spirituele praktyk, veral in die digter se laatwerk, sowel as postsekularisme en ekopsigologie sal vir hierdie doel ingespan word. Daar sal hoofsaaklik eksemplaries te werk gegaan word deurdat enkele kerngedigte in die bundel ontleed word, te wete "moniaal", " 'n eland staan by 'n kuil", "ongelowig is nie die regte woord nie" en "kerssonnet". Daar word aangetoon op welke wyse Krog kategorieë of gehele wat in moderne tye hulle relevansie verloor het, poëties nuut verwoord deur te fokus op die verbeelding van 'n groter geheel waarin plante, diere en mense interverbonde is en interafhanklik van mekaar bestaan. Sodoende word die grense van die paradigma van egosentrisme waarin moderne mense verval het, opgehef en bestaande religieuse grense word deurbreek deurdat holisme op kreatiewe wyse as nuwe werklikheid daargestel word.
Politieke transformatisme in Suid-Afrika: Implikasies vir die staat, die ekonomie en die samelewing
Authors: Duvenhage A
Published: January 2022

Vorme van sosiogeniëring, byvoorbeeld kolonisasie, apartheid en vorme van radikale sosialisme (Ujamaa - sosialisme in Tanzanië, en radikale grondhervorming in Zimbabwe), was meestal 'n mislukking met katastrofiese gevolge vir die onderskeie state, hul ekonomieë en selfs die betrokke samelewingsordes. Dikwels is die omgekeerde bereik van juis dít wat in die vooruitsig gestel is. Die mislukking van apartheid (soms voorgehou as afsonderlike ontwikkeling) is nog vars in die geheue as voorbeeld van bogenoemde. Uitgaande van die idee (of ideologie) van die Nasionaal Demokratiese Rewolusie, het die oorhoofse beleidsraamwerk van politieke transformasie in Suid Afrika beslag gekry - die teenvoeter vir die historiese apartheid- en koloniale praktyke. Die doel van hierdie ideologie is om, met behulp van radikale (transformatiewe verandering), 'n samelewing wat verenigend, nierassig, nieseksisties en ontwikkelingsgerig is te bewerkstellig. Die sentrale fokus is verteenwoordigendheid op alle vlakke van die samelewing met inbegrip van die staat, die ekonomie en die burgerlike samelewing. Hierdie navorsing stel as hipotese dat politieke transformasie, die ideologie wat in Suid-Afrika toegepas word, tot mislukking gedoem is en dat hierdie mislukking nie net reeds waarneembaar is nie, maar verreikende toekomstige implikasies inhou vir die staat, die ekonomie en die groter samelewing. Die doel van hierdie artikel is dus 'n grondige ondersoek na en kritiese ontleding van transformatisme as die heersende politieke ideologie in Suid-Afrika. Hierdie beoordeling geskied teen die agtergrond van die regstaatidee as norm, asook verbandhoudende demokratiese kriteria waarin politieke, ekonomiese en sosiale vryheid as normatiewe grondslag en vertrekpunt geneem word.
Die siel van protes: Die beweegredes vir, en belang en onderafdelings van protesaksie herbeskou
Authors: Bekker M
Published: January 2022

In 'n wêreld deurdrenk met geweld - beide subjektief en objektief beskou - tref mens protes as 'n teken van gemeenskaplike ontevredenheid aan. Die beweegrede onderliggend aan protesaksie word egter gereeld misken vir wat dit in werklikheid is, naamlik solidariteit met diegene wat onreg ly. Daar was die afgelope twee dekades plaaslik en internasionaal 'n skerp toename in openbare protes, met 'n gepaardgaande toename in teorieë wat oor die oorsake hiervan bespiegel. Ondanks 'n verskeidenheid voorstellings is dit nietemin steeds onduidelik "waaroor ons praat wanneer ons van protes praat", in die mate waarin die grondbeginsels van protes slegs binne beperkte epistemologiese gemeenskappe (en nie in die algemeen nie) oorweeg word. Hierdie artikel besin oor die aard van protes as 'n politieke handeling wat op 'n kontinuum wat wissel van opposisiepolitiek tot burgeroorlog lê. Hierdie kontinuum verskaf 'n gegradeerde beskouing wat uitdrukkings van ontevredenheid orden volgens die erns van die uitkoms. Voorts bied die artikel 'n abstrakte voorstelling van die onderskeie afdelings van protesvorming as sodanig, waaronder griewe, gebare en taktiese maatreëls. Van nader beskou, blyk hieruit dat protes getipeer kan word as 'n openbare uitdrukking van 'n niehegemoniese, etiese verbintenis tot geregtigheid, 'n optrede wat moed en koördinasie verg, en waarvan die uitkoms altyd onvoorspelbaar is; dit wil sê, 'n daad van liefde. Ten slotte word die episode van openbare geweld en plunder in Julie 2021 in Suid-Afrika aan die hand van die voorgestelde raamwerk ondersoek en bespreek.
Die rol van handgebare in oudiovisuele aanbiedings van teologiestudente: Belyning van teorie en praktyk
Authors: Carstens A
Published: January 2022

Kommunikasie in die 21ste eeu het grootliks multimodaal geword. 'n Verskeidenheid primêre modusse, byvoorbeeld geskrewe teks, mondelinge vertelling, beweging, kleur, klank en musiek, word ook elektronies "vertaal" en sekondêr deur rekenaars, selfone en tablette afgelewer. Een van die genres wat gekenmerk word deur multimodaliteit is oudiovisuele aanbieding. In studente se aanbiedings is spraak gewoonlik die primêre modus, en word aangevul deur teks, animasie (beweging), foto's en kleur. Die mondelinge aanbieding tree as deel van 'n multimodale ensemble op, waar die unieke eienskappe van elke modus benut word om betekenis oor te dra. Eers gee ek 'n definisie van die konsep "handgebaar", gevolg deur 'n uiteensetting van algemeen erkende gebareteorieë en tipologieë wat gebare indeel volgens semiotiese gebaretipes, handigheid (links, regs of beide), gekonvensionaliseerde handvorme en palm-oriëntasies, en beweging en posisie in die gebareveld. Daarna volg 'n beskrywing van 'n navorsingsprojek wat berus op die analise van ko-taalgebare in 'n korpus van 17 gevideo-graveerde mondelinge aanbiedings deur teologiestudente. Die artikel word afgesluit deur puntsgewyse advies vir die gebruik van gebare in studente se oudiovisuele aanbiedings. Die advies is sowel gegrond op teorieë en tipologieë van gebare as op die analise van die korpus. Waar dit relevant is, word verwys na handleidings oor kommunikasie en openbare redevoering.
Propagandataal: Kwantifiseerders en voor-naamwoorde
Authors: Maritz A
Published: January 2022

Verskeie studies is al oor die taalgebruik van propaganda gedoen, maar dikwels met behulp van kritiese diskoersanalise, wat die klem op magsverhoudinge plaas en wat dikwels gebruik word om teksspesifieke afleidings te maak. Met die doel om gesistematiseerde afleidings oor die taaleienskappe van propaganda in die breë te maak, word Sistemies Funksionele Linguistiek in hierdie artikel gebruik. Ná die sortering van tekste as propaganda- of niepropagandatekste (as kontrolegroep) met behulp van 'n inhoudelik-gebaseerde sorteringsmodel, is die gebruik van kwantifiseerders en voornaamwoorde in beide teksgroepe geanaliseer. Die studie is 'n kwalitatiewe studie: elke teksgroep bestaan uit agt tekste waarvan ses tekste Engels en twee Afrikaans is. Die tema van die tekste is oudpresident Jacob Zuma se betrokkenheid by die Nkandla- en staatskapingskan-dale in Suid-Afrika. Die gevolgtrekkings sluit die volgende in: niespesifieke kwantifiseerders kan in propa-gandatekste gebruik word om ware inligting te verdoesel en spesifieke kwantifiseerders kan weer gebruik word om wetenskapsdiskoers (wat mediadiskoers moet insluit) na te boots om geloofwaardigheid te verhoog. Voornaamwoorde kan gebruik word om spesifieke eienaar-skapskakels te maak, maar soos dit die propagandis se saak pas. Kataforiese voornaamwoorde (as deel van aanwysende voornaamwoorde) kan weer gebruik word om afstand te skep, wat die propagandis help om defleksie te bewerkstellig. Buiten vir die gewone kohesiefunksie. word die herhaling van sekere voornaamwoorde vir strategiese doeleindes gebruik. Alhoewel daar 'n ooreenkoms in beide teksgroepe bestaan wat die ideasionele metafunksie betref, maak 'n propagandis in 'n groter mate op die interpersoonlike funksie staat om 'n ekstra betekenislaag in die teks te integreer.
Onverpersoonlikingstrategieë in Afrikaans
Authors: Breed A , van Olmen D , ChanI J
Published: January 2022

Hierdie artikel ondersoek die verskillende strategieë wat Afrikaanse sprekers gebruik om aan te dui dat 'n konstruksie onpersoonlik is. Onpersoonlike konstruksies is konstruksies waar die (soms implisiete) subjek geparafraseer kan word as "mense in die algemeen", " 'n onbekende persoon" of "sommige mense". Hierdie onderwerp het al baie aandag in die taalkundeliteratuur gekry, maar die fokus was meestal op 'n beperkte aantal onverpersoonlikingstrategieë, soos die gebruik van persoonlike voornaamwoorde (bv. Jy leef net een keer), onbepaalde voornaamwoorde (byvoorbeeld Iemand het my beursie gesteel!) en passiewe konstruksies (byvoorbeeld My kar is gesteel). Volgens ons kan dié nou fokus in die literatuur toegeskryf word aan die feit dat die navorsingsmetodes (byvoorbeeld korpusstudies en vraelyste) wat tot op hede gebruik is om onverpersoonlikingstrategieë te ondersoek, navorsers slegs in staat stel om op deduktiewe wyse na die strategieë te kyk. Tot op hede is daar nog nie 'n studie uitgevoer om te bepaal i) watter verskillende moontlike onverpersoonlikingstrategieë deur Afrikaanse sprekers aangewend kan word nie, en ii) of daar bepaalde voorkeure vir sprekers bestaan oor watter strategieë om te gebruik in die verskillende en onderskeibare onpersoonlike kontekste. Hierdie ondersoek beantwoord hierdie twee vrae deur die resultate van 'n visuele vraelys - wat aan ongeveer 450 Afrikaanssprekende respondente gegee is om te beantwoord - te bestudeer.
Beleidsdiskriminasie, verandering en entrepreneurskap: Beperkte politieke regte vir "Kleurlinge" in Suid-Afrika tot 1979
Authors: Cloete F
Published: January 2022

Hierdie artikel kontekstualiseer, verduidelik en beoordeel die ontwikkeling van politieke regte vir "Kleurlinge" in Suid-Afrika, tot 1979. Dit word gedoen vanuit die teoretiese perspektief van beleidsentrepreneurs wat verskillende persoonlike, professionele en ander sosiale netwerke tot hulle beskikking gebruik om direkte beleidsbeïnvloeding te doen. Die artikel skets eers kortliks die teoretiese uitgangspunte en kenmerke van beleidsentrepreneurskap en -netwerkbeïnvloeding en som dan die ontwikkeling van politieke regte vir die "Kleurlingge-meenskap" in die land op, tot PW Botha die leierskap van die Nasionale Party oorgeneem het. Die artikel kontekstualiseer en fokus veral op die aanloop tot en die afloop van die Erika Theron-kommissie, wat 'n direkte rol gespeel het by die uiteindelike instelling van 'n fun-damentele nuwe staatsbestel in die land. Die ondersoek illustreer die toepassing en impak wat doelgerigte individuele beleidsentrepreneurskap en -netwerkbeïnvloeding deur strategies geposisioneerde individue, groepe en netwerke op fundamentele samelewingsverandering kan hê. Dit illustreer en staaf verder die belangrike kumulatiewe effek wat beide interne en eksterne politieke druk op beleidsverandering kan hê. Dit het belangrike implikasies vir huidige en toekomstige beleidsaanpassings in Suid-Afrika en in ander demokratiese beleidsveran-deringsprosesse.
Die verbruikersetiese gedrag van Suid-Afrikaanse bestuurders
Authors: Bisschoff C
Published: January 2022

Dié studie ondersoek die gedrag in verbruikersetiek wat onder Suid-Afrikaanse besigheids-bestuurders heers. Die studie ondersoek die etiese houdings, en vergelyk dit daarna met die spektrum van etiese gedrag wat die groep bestuurders openbaar. Die populasie van die studie bestaan uit bestuurders wat oor ten minste drie jaar bestuurservaring beskik en gegradueerd is. 'n Sneeubal-steekproef het 102 bruikbare vraelyste gerealiseer wat ontleed is nadat dit statistics voldoende bevind is deur Kaiser, Meyer en Olkin se toets om te bepaal of die steekproef voldoende is al dan nie. Nege van die 14 twyfelagtige gedragscenario's verskil statisties betekenisvol van die etiese houdings wat die bestuurders handhaaf, en dui daarop dat die bestuurders nie altyd so eties optree soos wat hul houdings voorhou nie. Die algemene tellings is egter bevredigend en beide die etiese houdings (2.47) en etiese gedrag (2.94) is onder die middelpunt waarde van 3.5. Voorts word die onderliggende faktore ook bepaal van die etiese gedrag deur 'n ondersoekende faktorontleding in te span. Drie faktore is geïdentifiseer, naamlik misleidende gedrag (37.04%), oneerlike optrede (13.71%), en prysvoordeel (9.77%). Die studie bevind verder dat daar nie betekenisvolle verwantskappe tussen die bestuurders se etiese gedrag en hul demografiese veranderlikes is nie. Die resultate is bemoedigend, selfs al tree die bestuurders meer oneties op as wat hul houdings voorstel, omdat die gedrag oor die algemeen as eties beskou word, en slegs drie uit die 14 scenario's 'n telling bo die 3.5 middel-punt het. Dit toon dat hulle oor die algemeen in hul persoonlike besluitneming etiese besluite maak. Daar is egter steeds ruimte vir verbetering.

Despite clear legal promulgations by section 27 of the Constitution and Children’s Act 38 of 2005, the best interests of children are generally undermined or ignored. The lack of respect for the rights of children is difficult to quantify; the extent to which “children are seen and heard” is under-reported. Culture, religion, patriarchy and socioeconomic condition are among the factors that exacerbate blatant disregard conditions for children’s rights. Health care professionals are not adequately informed about the rights of the child and how to ensure that their interest are protected during oral health care. Consequently, children may suffer neglect and harm during dental care. Practitioners must familiarize themselves regarding their responsibilities and roles when treating children. Additionally, teaching institutions and regulatory bodies must provide continuous professional development on legislation that regulates the protection of children within health care service. This case study seeks to provide a legal framework for oral health practitioners when dealing with consent for minors during dental care.

Published: January 2022

Deep learning has become increasingly popular and widely applied to computer vision systems. Over the years, researchers have developed various deep learning architectures to solve different kinds of problems. However, these networks are power-hungry and require high-performance computing (i.e., GPU, TPU, etc.) to run appropriately. Moving computation to the cloud may result in traffic, latency, and privacy issues. Edge computing can solve these challenges by moving the computing closer to the edge where the data is generated. One major challenge is to fit the high resource demands of deep learning in less powerful edge computing devices. In this research, we present an implementation of an embedded facial recognition system on a low cost Raspberry Pi, which is based on the FaceNet architecture. For this implementation it was required the development of a library in C++, which allows the deployment of the inference of the Neural Network Architecture. The system had an accuracy and precision of 77.38% and 81.25%, respectively. The time of execution of the program is 11 seconds and it consumes 46 [kB] of RAM. The resulting system could be utilized as a stand-alone access control system. The implemented model and library are released at https://github.com/cristianMiranda-Oro/FaceNet_EmbeddedSystem

Published: January 2022

The development of botanical insecticides as a novel and safer alternative strategy, botanical insecticides which contain plant extracts as active components are safer as well as environmentally friendlier than synthetic insecticides. The field experiment was conducted at Ginir district with the objectives to evaluate the Nimbecidine insecticide against field pea aphid and to determine the application rate and frequencies for the effective management of field pea aphid. The experiment was laid out in RCBD design with three (3) replication. The treatments include five rate of nimbecidine (3, 3.5, 4, 4.5 L/ha) and three frequencies (0, 1, 2 and 3). Aphid population significantly affected by the rate and frequency of nimbecidine at the rate 4.5 lt/ha the mortality reached from 27.89 to 10.67% on two times sprayed plots. The highest yield advantage of 35.61% and 33.86% over the untreated control was obtained from the plots treated at the rate of 4.5 and 4 lt/ha when sprayed two times. Therefore, Their use in pea aphid IPM at the rate of 4.5lt/ha at the frequency of two times application at flowering and pod setting stage provides good results.

Introduction: Burnout syndrome in some European countries is recognized as an occupational disease. In the past time, it has been identified predominantly in the service sectors such as healthcare, social services, mental health and education, but later it started to be predominant in other occupations with high job requirements and time pressure. The aim of this study was to assess the presence of burnout at work among the bank employees of Sarajevo Canton, Bosnia and Herzegovina.Methods: A cross-sectional study was conducted in banks (n = 6) located in Sarajevo Canton, Bosnia and Herzegovina, between January and April 2018. Employees filled out an anonymous questionnaire, after their written informed consent had been obtained. The study included employees regardless of their job positions and job seniority.Results: The total number of surveyed employees was 260. There are not statistically significant gender differences (p = 0.854¸ p < 0.05) compared to the total Maslach Burnout Inventory (MBI) score. Statistically significant differences in relation to the total MBI score were observed in the examinees who have been working in the banking sector between 15 and 20 years (p = 0.04; p < 0.05) and examinees working temporarily <2 h/week (p = 0.016; p < 0.05), that is, more than 8 h/week (p = 0.015; p < 0.05). Mid value and standard deviation of the score in the subscale of emotional exhaustion (EE) is 26.26 ± 11.15, which shows that one third of the examinees are in high risk of EE.Conclusion: We can conclude that less than one third of examinees are in high risk of burnout syndrome.

Published: January 2022

Objective: to assess vitamin D deficiency and hyperhomocysteinemia along with psychoemotional status in patients with vestibular migraine.

Material and methods. The neurovestibular examination of 23 patients was performed. All patients were diagnosed with vestibular migraine in accordance with the international criteria. The levels of 25-hydroxyvitamin D and homocysteine were assessed by enzyme-linked immunosorbent assay (ELISA). The effect of dizziness on everyday life was assessed according to the Dizziness Handicap Inventory (DHI). Psychoemotional status was investigated for all patients by using the following scales: Beck depression scale, Spilber–Hanin Scale, Toronto Alexithymia Scale (TAS-26).

Results. The mean level of 25-hydroxyvitamin D was 23±15 ng/ml, homocysteine – 11±3.4 μmol/L. The mean levels of situational and personal anxiety were 48.8±9 and 50.4±10.8, respectively. A correlation analysis revealed a significant positive correlation for Beck's depression parameters and DHI score (Spearman's criterion value 0.64, p=0.0016).

Conclusion. The data obtained evidence about a rather frequent detection of 25-hydroxyvitamin D insufficiency and deficit among patients with vestibular migraine that requires further evaluation, including expanding patients sample and/or comparison with other groups of patients. Of significance was to find an elevated level of anxiety and a correlation between the severity of dizziness (according to DHI score) and the level of depression (based on the Beck Scale).
