Academic literature on the topic 'Bora language'

Bor je bilo koji četinar roda Pinus koji pripada porodici Pinaceae. U Republici Srbiji nalaze se prirodne i ve&scaron;tačke &scaron;ume crnog bora Pinus nigra Arnold. Kora bora se vekovima koristila u tradicionalnoj medicini, međutim tek u novije vreme su otkriveni i potvrđeni njeni pozitivni biolo&scaron;ki efekti u medicini. Najpoznatiji komercijalni preparat kore bora je piknogenol, standardizovani ekstrakt kore francuskog primorskog bora Pinus pinaster Aiton, koji raste duţ obale jugozapadne Francuske. Pozitivni efekti koje ispoljava piknogenol, kao &scaron;to su antioksidativno, hipoglikemijsko, hipolipidemijsko delovanje, zasnovani su na njegovom visokom sadržaju fenolnih jedinjenja. Danas, i pored saznanja da je kora bora bogata sekundarnim metabolitima ona najče&scaron;će zavr&scaron;ava kao nusproizvod drvne industrije. Ciljevi ovog rada bili su ispitivanje kvalitativnih i kvantitativnih karakteristika i biohemijskih aktivnosti ekstrakata kore crnog bora Pinus nigra sa Mokre gore i Tare, dobijenih različitim rastvaračima; upoređivanje glikemijskog i lipidnog delovanja ekstrakta kore bora Pinus nigra sa komercijalnim preparatom piknogenol; uticaj ekstrakta kore bora Pinus nigra i piknogenola na delovanje standardnih antidijabetika metformina i gliklazida; kao i uticaj na parametre oksidativnog stresa nakon izlaganja životinja toksičnoj dozi paracetamola. In vitro ispitivanja su uključivala analizu ekstrakata dobijenih različitim rastvaračima. Ukupni sadržaj fenola, tanina, flavonoida i proantocijanidna, kao i ispitivanje antioksidativne aktivnosti kroz pet različitih metoda, određivani su spektrofotometrijski. Vr&scaron;ena je analiza ekstrakata kore bora visokoefikasnom tečnom hromatografijom (HPLC). In vivo ispitivanje je rađeno na 156 albino laboratorijska pacova soja Wistar. Eksperimentalne ţivotinje su tokom 7 dana per os primale ekstrakt kore crnog bora poreklom sa Mokre gore 100 mg/kg, koji je pokazao najbolju aktivnost, piknogenol 50 mg/kg, metformin 100 mg/kg, gliklazid 10 mg/kg, kao i njihove kombinacije. Za ispitivanje uticaja primenjivanih supstanci na glikemiju ţivotinja kori&scaron;ćeni su test oralnog podno&scaron;enja glukoze i indukcija trajne hiperglikemije aloksanom. Od biohemijskih parametara u serumu je određivana koncentracija lipida, kao i parametric pokazatelji funkcije bubrega i jetre. Ex vivo ispitivanja uključivala su određivanje intenzitet lipidne peroksidacije i anktivnosti enzima antioksidativne za&scaron;tite u homogenatu jetre ispitivanih ţivotinja, nakon primene toksične doze paracetamola. HPLC analizom ekstrakata kore crnog bora utvrđeno je da ekstrakti poreklom sa Mokre gore i Tare u najvećoj meri sadrţe taksifolin, a zatim katehin, njegove derivate, kafenu kiselinu i epikatehin. PotvrĎen je visok antioksidativni kapacitet piknogenola, ali takođe i značajan antioksidativni kapacitet ekstrakata kore crnog bora, sa najboljim rezultatima kod ekstrakta poreklom sa Mokre gore. Sedmodnevni tretman ekstraktom kore bora 100 mg/kg, metforminom 100 mg/kg, gliklazidom 10 mg/kg i piknogenolom 50 mg/kg, kod ţivotinja sa aloksanski izazvanim dijabetesom, doveo je do sniženja glikemije u krvi. Uočeno je povećanje konentracije HDL holesterola i značajno sniženje serumskih triglicerida kod dijabetičnih i normoglikemičnih ţivotinja koje su primale piknogenol, ekstrakta kore bora, gliklazid i metformin u poređenju sa kontrolnom grupom ţivotinja. Zajednička primena ekstrakta kore bora i standardnih antidijabetika značajno je snizila vrednosti AST, ALP i direktni bilirubin u grupi dijabetičnih i normoglikemičnih ţivotinja u odnosu na kontrolnu grupu, čime se ukazuje na potencijalno hepatoprotektivno delovanje ekstrakta kore crnog bora. O&scaron;tećenje jetre izazvano toksičnom dozom paracetamola je potvrđeno ispitivanim parametrima, uključujući oksidativni status u homogenatu jetre i histolo&scaron;ka ispitivanja. Rezultati na&scaron;eg istraživanja su pokazali da piknogenol 50 mg/kg, kao i ekstrakt kore crnog bora 100 mg/kg značajno smanjuju nivo MDA u poređenju sa kontrolnom grupom i grupom koja je primala paracetamol. Na osnovu rezultata istraţivanja može se zaključiti da primena piknogenola i ekstrakta kore crnog bora: ublaţava poremećaj homeostaze glukoze, utiče povoljno na lipidni status, značajno potencira antihiperglikemijsko delovanje metformina i hipoglikemijski efekat gliklazida, sprečava poremećaj biohemijskih parametara pokazatelja funkcije jetre i bubrega u serumu ispitivanih životinja i ispoljava značajno in vitro antioksidativno delovanje i sprečava o&scaron;tećenje jetre laboratorijskih životinja izazvano toksičnom dozom paracetamola.<br>A pine is any conifer in the genus Pinus of the family Pinaceae. In the Republic of Serbia there are natural and artificial forests of black pine Pinus nigra Arnold. Pine bark has been used for centuries in traditional medicine, but only recently its positive biological effects has been revealed and confirmed in medicine. The most famous commercial pine bark product is Pycnogenol, a standardized extract of the French maritime pine bark (Pinus pinaster Aiton), which grows along the coast of southwestern France. The positive effects of Pycnogenol, such as antioxidant, hypoglycemic, hypolipidemic, are based on its high content of phenolic compounds. Nowdays, despite the knowledge that the pine bark is rich in secondary metabolites, it usually ends up as a by-product of the wood industry. The objectives of this dissertation were to investigate the qualitative and quantitative characteristics and biochemical activities of the black pine (Pinus nigra) extracts from Mokra gora and Tara, obtained by different solvents; comparison of glycemic and lipid action of Pinus nigra bark extract with commercial product Pycnogenol; the influence of black pine bark extract and Pycnogenol on the action of standard antidiabetics metformin and gliclazide; as well as the influence on the parameters of oxidative stress in animals exposed to the toxic dose of paracetamol. In vitro analyses included the analysis of extracts obtained with different solvents. The total phenolic, tannin, flavonoid and proanthocyanidin content, as well as the antioxidant activity tests, were determined spectrophotometrically. High-efficiency liquid chromatography (HPLC) was performed in order to determine black pine bark extract content. In vivo analyses was performed on 156 albino Wistar laboratory rats. Experimental animals received for 7 days per os: black pine bark extract obtained from Mokra gora 100 mg/kg, which showed the best activity; Pycnogenol 50 mg/kg; metformin 100 mg/kg; gliclazide 10 mg/kg; and their combinations. An oral glucose tolerance test and the aloxan-induced hyperglycaemia were used to examined the effects of the substances on experimental animals. Biochemical parameters, the lipids concentration and parameters of the kidney and liver function, were determined in animal serum. Ex vivo analyses included determination of lipid peroxidation activity and the activity of antioxidant protection enzymes in liver homogenates of the test animals, after administration of a toxic dose of paracetamol. HPLC analysis of black pine bark extracts obtained from Mokra gora and Tara showed the greatest content of taxifolin, then catechin, and its derivatives, caffeic acid and epicatechin. A high antioxidative capacity of Pycnogenol was confirmed, but also a significant antioxidant capacity of black pine bark extract, with the best results in the extract obtained from Mokra gora. Seven-day treatment in aloxan-induced diabetes animals with 100 mg/kg black pine bark extract, metformin 100 mg/kg, gliclazide 10 mg/kg and Pycnogenol 50 mg/kg led to a decrease of serum glycemic index. There was an increase in the HDL cholesterol concentration and a significant reduction in serum triglycerides in diabetic and normoglycemic animals which received Pycnogenol, black pine bark extract, gliclazide and metformin compared to the control group. Concomitant usage of the black pine bark extract and standard antidiabetics significantly reduced the levels of AST, ALP and direct bilirubin in the group of diabetic and normoglycemic animals compared to the control group, indicating the potential hepatoprotective action of the black pine bark extract. Damage to the liver caused by the toxic dose of paracetamol was confirmed by the liver homogenate oxidative status and histological examination. The results of our study have shown that Pycnogenol 50 mg/kg, as well as 100 mg/kg black pine bark extract significantly reduce the level of MDA in comparison with the control and the paracetamol treated group. Based on the results of the dissertation, it can be concluded that the use of Pycnogenol and black pine bark extract alleviate glucose homeostasis disorder; positively affects the lipid status; significantly increases the antihyperglycemic effect of metformin and the hypoglycemic effect of gliclazide; prevents impairment biochemical parameters of the liver and kidney function in the serum of the experimental animals; significantly exhibits in vitro antioxidant activity and prevents liver damage caused by toxic dose of paracetamol in experimental animals.

Knowledge of Indigenous language and identity for Australian Indigenous children is vital. Despite this there has been little research into the effects that living culture practice affords Australian Indigenous children through learning heritage language. Yarrabil (to sing) is one way in which Indigenous youth can participate in learning Indigenous language. Through a series of surveys, wula bora (focus group) sessions, interviews and reflections, the jarjum (children) of the Yugambeh language region assisted to discover how the process of participation in an urban Aboriginal children’s language choir can play an integral part in youth leadership, language acquisition, well-being (self-efficacy), and Identity and Aboriginality. The research also demonstrates how a language choir can safe-guard language and culture whilst building socio-cultural capital within an Indigenous community. The National Indigenous Languages Survey Report of 2005 listed the Aboriginal language Yugambeh of the Gold Coast, Logan and Scenic Rim regions of South-East Queensland, Australia as endangered. This thesis investigates an alternate way to girrebba (wake up) a sleeping language and engage youth in the process of learning their heritage language. The ‘Yugambeh Language and Song project’ provides academic knowledge in a relatively unstudied field, supports living culture practice and provides a model to assist other Indigenous communities to sing their language alive.<br>Thesis (Masters)<br>Master of Arts Research (MARes)<br>School of Humanities, Languages and Social Science<br>Arts, Education and Law<br>Full Text

Позоришни редитељ Боривоје Ханауска незаобилазан је у проучавању делатности Српског народног позоришта у периоду после Другог светског рата. Ханауска је од 1945. до 1967.

Hanausca directed thirty plays in the Serbian National Theatre from 1945-1967(with a break from 1948-1952). This study describes the work of the theatre director Borivoje Hanausca in the Serbian National Theatre being one of the most significant directors in it and in the best way presents his contribution to the development of directing in the Serbian post-war theatre. The research methods in this work are historical andtheatrical; reconstruction and analysis of all the thirty plays Hanausca directed in the Serbian National Theatre as well as the synthesis of the results that were obtained. This study includes each part of his work in his plays, on the basis of the material which was available. He considered every single detail of his plays important; he supported Serbian plays to be both present and heard from the stage as much as possible and he particularly took care of visual aspects. He is one of thecreators of the new approach to theatre play directing. Poetics he had deep within himself came out and was present, more or less, in his plays. This work is illustrated with posters and photographs from his plays and there is a list of all plays he directed and the names of all the people involved in the performances, the number of performances in the Serbian National Theatre and performed on tour, as well as the number of audiences.

This research was designed to provide information concerning the developmental differences in early language production and comprehension between 21 month-old first born and second born children. Furthermore, the study explored the assumption that more opportunities to hear conversations between the parent and the older sibling provide an advantage for second born children in learning personal pronouns.<br>Spontaneous speech productions of 16 first born children were compared to those of 16 second born children while in dyadic interactions with their mothers. First born children were observed in two 25 minute free-play dyadic interactions with their mothers. Second born children were observed in one 25 minute free-play mother-child dyadic interaction and in one 25 minute free-play mother-child-older sibling triadic interaction. All children were administered controlled tasks involving production and comprehension of first and second person pronouns.<br>Compared to first borns, second born children are not significantly delayed in general language development. Second borns' speech productions differ depending on whether or not their older sibling was present. (Abstract shortened by UMI.)

<p>U ovoj studiji, sprovedeno je deset eksperimenata kako bi se ispitale karakteristike i mehanizam uticaja jezika u procesu diskriminacije boja. Karakteristike uticaja jezika su ispitivane u prvom delu studije kroz testiranje efekta kategoriĉke percepcije boja (KPB efekta) na granicama kategorija boja u srpskom jeziku: (1) plavo i teget i (2) crveno i bordo, kod govornika ĉiji je maternji jezik srpski i dvojeziĉnih govornika maĊarskog i srpskog jezika. Pre sprovoĊenja eksperimenata, primenom zadatka izlistavanja boja je, po prvi put, ispitivana kognitivna zasićenost naziva za boje u srpskom jeziku. Rezultati ovog zadatka su pokazali da su nazivi plavo i crveno visoko kognitivno zasićeni za govornike srpskog jezika, te se mogu klasifikovati kao osnovni nazivi, dok se teget i bordo mogu klasifikovati kao zasićeni ne-osnovni nazivi koji su na putu da steknu status osnovnih. Rezultati sprovedenih eksperimenata su pokazali da se, kod govornika ĉiji je maternji jezik srpski, KPB efekat moţe zabeleţiti i u zadatku diskriminacije plavih nijansi (eksperiment 1) i u zadatku diskriminacije crvenih nijansi (eksperiment 2). Nasuprot tome, kod dvojeziĉnih govornika, KPB efekat je zabeleţen samo u diskriminaciji crvenog dela prostora boja (eksperiment 4) koji je na sliĉan naĉin opisan u oba jezika ovih govornika. Dobijeni rezultati govore u prilog prethodnim nalazima da KPB efekat zavisi od naĉina na koji pojedinaĉni jezici opisuju prostor boja i dopunjuju ih prvom demonstracijom KPB efekta u zadatku diskriminacije crvenog dela prostora boja. Takođe, dobijeni rezultati pokazuju da je kognicija boja dvojeziĉnih govornika pod uticajem jezika koji uĉestalije koriste, ĉime se dopunjuju prethodni nalazi o kompleksnosti dvojeziĉne kognicije boja. Mehanizam uticaja jezika u procesu diskriminacije boja je ispitivan u drugom delu studije kroz testiranje uloge verbalnog i vizuelnog kodiranja u KPB efektu. Dve vrste kodiranja su ispitivane u zadacima diskriminacije plavih i zelenih nijansi u kojima je primenjena verbalna ili vizuelna interferencija, koja je osmi&scaron;ljena za potrebe ove studije. Dobijeni rezultati su potvrdili implikacije jedne struje prethodnih studija i pokazali da tip kodiranja zavisi od memorijskog opterećenja zadatka diskriminacije &ndash; u zadacima bez memorijskog opetrećenja, KPB efekat se dominantno zasnivao na vizuelnom kodiranju (eksperimenti 5-8), dok se u zadacima sa memorijskim opterećenjem, dominatno zasnivao na verbalnom kodiranju (eksperiment 9). Dobijeni rezultati su, takođe, pokazali da odnos dve vrste kodiranja zavisi od vrste interferencije primenjene u zadatku diskriminacije boja &ndash; primena verbalne interferencije je usmeravala paţnju ispitanika na verbalni aspekt zadatka, ĉak i kad je vizuelno kodiranje bilo dominantno (eksperimenti 5-7). MeĊutim, kada je u zadatku diskriminacije primenjena vizuelna interferencija (eksperimenti 8 i 10) to nije bio sluĉaj &ndash; tada su ispitanici obraćali dodatnu paţnju na vizuelne aspekte zadatka. Ovakvi rezultati ukazuju na kompleksnu interakciju jezika i drugih kognitivnih procesa i pro&scaron;iruju prethodne nalaze o sloţenom mehanizmu uticaja jezika u procesu diskriminacije boja. Demonstracijom KPB efekta u jo&scaron; jednom savremenom jeziku, u ovoj studiji je potvrđeno shvatanje o tome da naĉin na koji jezici opisuju prostor boja ima kompleksan uticaj na izvedbu govornika u kognitivnim zadacima sa obojenim stimulusima. Ispitivanje specifiĉne jeziĉke kategorizacije prostora boja u srpskom jeziku nam je omogućilo da pokaţemo da KPB efekat nije vezan samo za nazive za boje koji se u jeziku smatraju osnovnim i na osnovu toga iznesemo predlog o razmatranju KPB efekta u kontekstu &scaron;ire grupe naziva za boje u jezicima. Na taj naĉin, ispitivanje KPB efekta bi se moglo pro&scaron;iriti na veću grupu jezika i na razliĉite delove prostora boja, &scaron;to bi znaĉajno doprinelo razumevanju njegove prirode. Na kraju, ĉinjenica da je u ovoj studiji, po prvi put, ispitivana kognicija boja govornika srpskog jezika, omogućila nam je da pruţimo preliminarne rezultate o reĉniku boja srpskog jezika iz ugla kognitivne psihologije.</p>

The proposed image optimization model enhancescolour distinction and gamut for users with different severities of colourblindnesswhile preserving the image naturalness. The used methodologicalframework, including a quantitative analysis of computer simulations, ananalysis of eye-tracking data and a subjective evaluation of the perceivedimage quality, provides systematic and reliable effectiveness verification ofthe proposed colour adaptation methods.

Aims: This thesis sets out to assess the long-term speech, language and intellectual abilities of children born very prematurely (less than 33 weeks' gestational age) – and to investigate the neuroanatomical correlates of any deficits identified. Method: The study participants (n=50, mean age 16 years) consisted of a representative sample that was recruited from a prospective follow-up study at University College Hospital (London). This included children with a wide spectrum of brain injuries (identified at birth) matched with a term-born control group (n=30). An extensive battery of standardised assessments was administered, including measures of expressive and receptive language, vocabulary, speech-motor control and intelligence. All participants underwent neuroimaging, including diffusion-weighted MRI (DWI). Functional MRI was also used to determine hemispheric language lateralisation. Potential neural correlates of intelligence, speech and language were explored using manual tracing, voxel-based morphometry and DWI-tractography of relevant white matter pathways, such as the language-associated arcuate fasciculus and the speech-motor fibres of the corticobulbar tract (CBT). Results: In comparison to controls, the preterm group had a lower mean IQ score and increased incidence of speech and language problems. Conventional MRI showed abnormalities in more than half of the preterm children, most commonly within the periventricular and callosal white matter. Global brain white matter volume was also reduced in the preterm sample and explained a substantial proportion (70%) of the variance in their IQ scores. Problems with oromotor control were found to be associated with specific abnormalities in the posterior limb of the internal capsule (which contains the CBT); and the degree of language impairment was linked to a reduction in the volume of interhemispheric connections between the temporal lobes. Conclusions: This study has shown that preterm birth is associated with persistent changes in global, commissural and periventricular white matter (identifiable in adolescence) and has established robust neuroanatomical correlates of long-term outcomes in general intelligence, speech and language abilities.

In New Zealand, approximately 10% of births are considered premature, that is less than 37 weeks gestation. With advances in medical technology, young infants are surviving gestation periods as few as 23 weeks. It is expected that many of these severely premature infants will demonstrate some problem in their academic, or cognitive function including language functioning. It is agreed that children who are born severely premature often present with language problems, the nature of the difficulties are not clear. Research examining language abilities that involve cognitive functions such as inference generation have demonstrated that children born prematurely exhibit difficulties with phonologic short-term memory and executive function. Language tasks such as inference understanding require children to integrate real-world knowledge with the linguistic information to generate and produce language that is more complex. The aim of this study was to discover if the language of children born severely premature differs from that of language-age matched peers. This study examined high-level language abilities of school-age children born severely prematurely, specifically, language tasks that involved executive functions including working memory, story inferencing, and recognising absurdities. Six children who were born less than 28 weeks gestation participated in this study. Their results on the above measures were compared to a language-aged matched comparison group, determined by performance on a standardised test. It was hypothesised that the children born severely premature would not differ from their language-age matched peers on measures of general language ability but differences would exist on measures of language processing and inferencing. The findings overall showed little difference between the preterm group and their language-age matched peers on measures except for the measure of chronological age. Although no group difference was found for the measure of working memory, a larger variance on this measure was observed in the preterm group.

Lumbalni bol predstavlja jedan od najučestalijih zdravstvenih problema dana&scaron;njice. Pružanje zdravstvene nege je stresan i težak fizički posao, te spada u grupu visoko-rizičnih poslova za nastanak lumbalnog bola, pa samim tim medicinske sestre &ndash; tehničari predstavljaju vulnerabilnu populaciju. Osnovni ciljevi ovog istraživanja bili su da se utvrdi prevalencija i faktori rizika za nastanak lumbalnog bola kod medicinskih sestara- tehničara, kao i mere prevencije. Istraživanje je sprovedeno u pet zdravstvenih ustanova sa područja Vojvodine u obliku studije preseka, anketiranjem medicinskih sestara &ndash; tehničara. Za ispitivanje je kori&scaron;ćen modifikovani Nordijski upitnik. Rezultati pokazuju veoma visoku prevalenciju lumbalnog bola među medicinskim sestrama- tehničarima, oko 94%. Ispitanici su bili uglavnom ženskog pola, prosečne starosti oko 38 godina. Najveći broj ispitanika ima srednju stručnu spremu. Istraživanjem je utvrđeno da postoji statistički značajna povezanost lumbalnog bola sa porastom godina života i dužine ekspozicionog radnog staža. Takođe, statistički visoko značajna korelacija nalazi se između porasta BMI i lumbalnog bola. Najzastupljeniji poslovi zdravstvene nege koje ispitanici sa lumbalnim bolom obavljaju su: pozicioniranje pacijenata, podizanje i presvlačenje pacijenata u postelji i podela terapije. Statistički značajno veća zastupljenost lumbalnog bola javlja se kod ispitanika koji sami obavljaju negu u odnosu na one koji imaju pomoć. Medicinske sestre &ndash; tehničari koji pripadaju grupi sa vi&scaron;im nivoom stresa na radnom mestu imaju znatno veći rizik za pojavu lumbalnog bola. Smenski rad (naizmenične dnevne i noćne smene od 12 sati) i prekovremeni rad duži od 8 sati dnevno, podizanje tereta većeg od 25 kg i broj pacijenata koje medicinska sestra &ndash; tehničar zbrinjava tokom radnog vremena nemaju značajnu povezanost sa pojavom lumbalnog bola. Oko tri četvrtine ispitanika nije izostajalo sa posla zbog bola. Samo oko 8% ispitanika je promenilo radno mesto zbog lumbalnog bola i ide redovno na periodične lekarske preglede. Kod mera prevencije neophodno je staviti akcenat na smanjenje fizičkog opterećenja donjeg dela leđa i smanjenje ručnog preno&scaron;enja tereta. Primenom adekvatnog ergonomskog pristupa, boljom organizacijom rada, podsticajnom atmosferom na poslu i spremno&scaron;ću nadležnih struktura da iskažu veću brigu prema zaposlenima, smanjila bi se učestalost pojave lumbalnog bola.<br>One of the today&rsquo;s most frequent health problems is the low back pain. Nursing is stressful and hard physical job which belongs to the group of high-risk jobs that could cause low back pain and therefore medical nurses/technicians represent the vulnerable population. Determination of prevalence, risk factors and prevention of the low back pain were the main goals of this research. The research in the form of cross-sectional study was conducted with nurses filling in the surveys within five medical institutions in Vojvodina. The modified Nordic questionnaire was used for the surveys. The results show very high prevalence of the low back pain, cca 94%, among medical nurses. Most of the respondents were females, who finished high school education, at average age of 38 years. The study showed that there is a statistically significant coherence between low back pain, ageing and working experience as a nurse. There is also a statistically significant coherence between the low back pain and the increase of the BMI. The most common nursing jobs that respondents with the low back pain do are: positioning of patients, lifting patients, dressing patients in bed and giving therapy. The low back pain with the respondents who do the nursing just by themselves is statistically significantly more present then with the respondents who do the nursing with help. Nurses who suffer more stress at their workplaces have a significantly higher risk to develop low back pain. Working 12 hour shifts (alternately day and night shifts), overtime work, more then 25 kg weight lifting and number of patients for nursing per nurse during working hours have no significant correlation with the low back pain occurrence. About three quarters of the respondents had no absence from work caused by the low back pain. Only 8% of the respondents changed their workplace because of the low back pain and have regular health checks. To prevent the low back pain it is necessary to emphasize the physical reduction of the load on the lower back and manual handling of loads. The frequent low back pain with the nurses could be reduced with the appropriate ergonomic access, better work organization, a supportive atmosphere at work and the willingness of responsible authorities to express greater concern about the employees.
