V prispevku predstavljamo rezilientnost kot raziskovalni fenomen, ki se v literaturi pojavlja v povezavi z dobro življenjsko prilagodljivostjo in prožnostjo ljudi v različnih težkih, prelomnih ...življenjskih situacijah. V ospredje postavljamo preskok, ki so ga pionirske študije naredile v raziskovalni paradigmi, ko so namesto modela, usmerjenega v problem, prevzele model rezilientnosti, ki se tesno navezuje na sodobne principe vseživljenjskega učenja. Iz pregleda različne literature sintetiziramo glavna spoznanja, opredelimo ločnice štirih raziskovalnih valov in poudarimo sodobno pojmovanje rezilientnosti. To nam služi tudi kot podlaga za utemeljitev slovenskega termina »življenjska odpornost in prožnost«. Raziskave s področja rezilientnosti jasno zarisujejo smernice za preventivno ekosistemsko delovanje. V prispevku se omejujemo na kontekst vzgoje in izobraževanja, saj so možnosti za preventivno krepitev posameznika tesno povezane s formalnimi in neformalnimi oblikami učenja. V tem konceptualnem okviru poudarjamo ključne varovalne dejavnike in kompetence, ki za posameznika pomenijo zunanje in notranje vire moči za rezilienten odziv v življenjskih preizkušnjah. Prispevek strnemo z orisom značilnosti »rezilientne« osebe.
Introduction. The pandemic of obesity in adolescents is one of the challenges of public health.
Aim. The aim of this study was to examine the association of overweight with demographic, socioeconomic ...and lifestyle factors among Serbian adolescents.
Method. A cross-sectional study of 2139 adolescents aged 10 to 19 years was carried out. Data used in this study were from the 2006 Health Survey. In accordance with the international sex- and age-specific Body Mass Index cut-off points, all participants were classified as being normal weight or overweight, including obese. The association between the risk factors and overweight were examined using a multivariate logistic regression model.
Results. The study showed that 28.9% of boys and 17.0% of girls were overweight, while 14.5% of boys and 8.1% of girls were obese. Boys were more likely to be overweight/obese, compared with girls. Being younger (p< 0.01 for 14 to 15 years) and (p< 0.01, for 16 to 19 years), engaging in physical activities that last less than 7 hours a week, in such a manner that they breathe quickly and become sweaty, (p< 0.01) and skipping breakfast (p< 0.05) were risk factors significantly associated with overweight among adolescents. No significant association was found with wealth index.
Conclusion. These findings should be an integral part of further preventive interventions, especially oriented towards younger adolescents, who are physically inactive, have a habit of skipping breakfast and are boys.
Namen. Pandemija debelosti pri mladostnikih predstavlja enega večjih izzivov za javno zdravje.
Cilj. Cilj te raziskave je bil preveriti povezanost prekomerne telesne teže med srbskimi mladostniki z demografskimi in s socialno-ekonomskimi dejavniki ter z dejavniki, ki so povezani z načinom življenja.
Metoda. Narejena je bila presečna študija z 2.139 mladostniki, ki so bili stari od 10 do 19 let. Za podatke v tej študiji so bile uporabljene vrednosti iz Health Survey 2006. Glede na mednarodno sprejete vrednosti indeksa telesne mase, povezane z odgovarjajočim spolom in starostjo, so bili vsi udeleženci uvrščeni v skupine z normalno težo, s prekomerno telesno težo in z debelostjo. Za ugotavljanje povezave med dejavniki tveganja in prekomerno telesno težo je bila uporabljena statistična metoda multivariantne logistične regresije.
Rezultati. Raziskava je pokazala, da je imelo 28,9% fantov in 17,0% deklet zvišano telesno težo, in sicer je bilo 14,5% fantov in 8,1% deklet debelih. V primerjavi z dekleti so bili fantje debelejši ali so imeli zvišano telesno težo. Za naslednje dejavnike tveganja smo ugotovili statistično pomembno povezavo s prekomerno telesno težo med mladostniki (starost 14-15 let (p<0,01) in 16-19 let (p<0,01)), ukvarjanje s telovadbo, ki povzroča hitro dihanje in potenje manj kot 7 ur dnevno(p< 0,01), ter vsakodnevno izogibanje zajtrku (p< 0,05). Na drugi strani ni statistično pomembne povezave med zvišano telesno težo/debelostjo in indeksom družinskega bogastva.
Zaključek. Ugotovitve naše študije bi lahko imele vpliv na preventivne ukrepe, ki bi bili posebej usmerjeni v mladostnike moškega spola, ki ne zajtrkujejo in se ne ukvarjajo z redno telesno aktivnostjo.
Uvod: Opravljena je bila analiza pojavljanja dejavnikov tveganja nezdravega načina prehranjevanja med odraslimi prebivalci Slovenije glede na biološke in sociodemografske spremenljivke.

Uvod. Med nosečnostjo kadi 15 % do 25 % žensk. Znanstveni dokazi kažejo, da izpostavljenost kajenju povzroča nižjo porodno težo. Cilj te študije je oceniti povezavo med kajenjem med nosečnostjo, ...socialnodemografskimi značilnostmi matere in nizko porodno težo. Metode. Podatki so bili pridobljeni iz 1572 vprašalnikov, ki so jih izpolnile vse ženske, ki so v obdobju od leta 2008 do leta 2010 rodile v učni bolnišnici za ginekologijo »S. Anna« v Torinu (Italija). Za oceno povezave med socialno-demografskimi značilnostmi in porodno težo je bila uporabljena multipla logistična analiza; sledil je postopni pristop z »vzvratnim izločanjem« in ocena ustreznosti modela s pomočjo Hosmer- Lemeshowega testa. Rezultati. Univariatna analiza je razkrila, da kajenje cigaret (17 %), nižja stopnja izobrazbe (13 %) in ženski spol dojenčka (13 %) predstavljajo dejavnik tveganja, saj povečujejo tveganje, da bo imel otrok nizko porodno težo. Analiza z logistično regresijo je pokazala, da sta gestacijska starost in kajenje matere statistično povezani spremenljivki. Zaključki. Rezultati potrjujejo, da se porodna teža povečuje sorazmerno z gestacijsko starostjo ter da kajenje matere in spol otroka (ženski) povečujeta tveganje za nižjo porodno težo ob rojstvu. Logistična regresija dokazuje, da povezava med kajenjem matere in nizko porodno težo pomeni povečano tveganje za celotno populacijo (RO = 2,85), tako za novorojenčke moškega (RO = 3,45) kot tudi ženskega spola (RO = 2,44)
Nanotechnology is the term given to those areas of science and engineering where the phenomena take place at nanoscale dimensions. Nanoparticles are particles with <100 nm in one dimension. They have ...different physical, chemical, electrical and optical properties than those that occur in bulk samples of the same material. Understanding these nanoscale properties and finding ways to engineer new nanomaterials will have a revolutionary impact, from more efficient energy generation and data storage to improved methods for diagnosing and treating diseases. Nanotechnology is poised to become a major factor in the world's economy and part of our everyday lives in the near future. Hundreds of tonnes of nanoparticles already enter the environment annually, but still very little is known of their interactions with biological systems. Recent studies indicate that some nanoparticles are not completely benign to biological and environmental targets. The challenge for toxicologists is to identify key factors that can be used to predict toxicity, permit targeted screening, and allow material scientists to generate new, safer nanoparticles with this structure-toxicity information in mind. The aim of this paper is to summarize some known facts about nanomaterials and discuss future perspectives, regulatory issues and tasks of the emerging branch of toxicology, that is, nanotoxicology.
Nanomateriali izboljšujejo kvaliteto našega Življenja, zato bo njihova uporaba na različnih področjih Življenja dramatično narasla. Po nekaterih ocenah bo imela nanotehnologija večji vpliv na druŽbno kot ga je imela industrijska revolucija. Kot posledica razmaha nanotehnologije se bo povečala poklicna in javna izpostavljenost nanodelcem ter izpostavljenost okolja. Nanodelci, ki nas najbolj zanimajo, so strukture, ki imajo v eni dimenziji manj kot 100 nm, in jih je izdelal človek. Njihove lastnosti se zaradi njihove majhnosti bistveno razlikujejo od lastnosti, ki jih imajo večji delci enake kemijske sestave. Šele v zadnjem času so se začela pojavljati vprašanja in vzpodbujati raziskave o potencialni nevarnosti nanodelcev. Trenutni rezultati toksikoloških študij potrjujejo kvarne učinke nanodelcev in navajajo, da nanodelci najverjetneje delujejo na organizem preko oksidativnega stresa. Študije nakazujejo številne posebnosti nanodelcev pri interakcijah s celicami, tkivi in organizmi. Najverjetneje je ta trenutek pomembno pridobiti čim več ustreznega znanja za oblikovanje regulative na področju varne proizvodnje in uporabe nanodelcev. Namen prispevka je povzeti Že znana dejstva o nanodelcih in predstaviti naloge nove smeri v toksikologiji, nanotoksikologije. V prispevku je povzeta najnovejša regulativa na področju ugotavljanja in zagotavljanja varnosti proizvodov nanotehnologij, navedene so nekatere koristne baze podatkov, razprave ter nacionalne in mednarodne smernice na področju nanotehnologije.
Introduction. 15 to 25% of women smoke during pregnancy. Scientific evidence suggests that exposure to smoking causes decreased birth weight. The aim of this study was to assess the correlation ...between smoking during pregnancy, maternal sociodemographic characteristics, and low birth weight. Methods. Data were derived from 1572 questionnaires administered to each woman that gave birth at the Gynecology Teaching Hospital “S. Anna” in Turin (Italy) during the period from 2008 to 2010. Multiple logistic analysis was used to evaluate the association between socio-demographic characteristics and birth weight; the stepwise approach with a “backward elimination” procedure was followed, and the goodness of fit of the model was estimated using the Hosmer-Lemeshow test. Results. The univariate analysis revealed that smoking cigarettes (17%), having a lower educational level (13%), and female sex of the infant (13%) seem to be risk factors, as they increase the risk of having a low birth weight child. Logistic regression analysis showed that gestational age and maternal smoking are the statistically associated variables. Conclusions. The results confirmed that birth weight increases proportionally with the length of the gestational age and that maternal smoking and the child’s sex (female) increase the risk of having a lower birth weight. Logistic regression demonstrated that the association between maternal smoking and low birth weight shows an increased risk for the whole population (OR=2.85), for male (OR=3.45) and for female newborns (OR=2.44)

Potrošniška družba, družba tveganja in družba z nanja so samo nekatere oznake, ki poskušajo opisati socialne, ekonomske, kulturne in politične spremembe, ki so se z godile v drugi polovici dvajsetega ...stoletja. Za čas globalizacije je na ravni edukacijskih politik z načilno, da tudi številčne in ekonomsko bolj razvite nacije nimajo pravih možnosti v globaliziranem svetu, če ne bodo vlagale v edukacijo, katere kakovost bi presojali skladno z mednarodnimi standardi. Od tod izhodišča za razpravo o pomembnosti permanentnega izobraževanja, kamor spada tudi razprava o izobraževanju odraslih.
V prvem delu članka nas zanima vprašanje opredeljevanja zakonitosti človekove narave in njenih zakonov delovanja s posebnim poudarkom na sposobnostih in zmogljivostih odraslih za učenje. Ker pa se sposobnosti za učenje ohranjajo in oblikujejo bolj v tistih družbah, ki znajo dovolj sistematično pristopati k problemu vseživljenjskega učenja, se po drugi strani pokaže, da o vsem tem odločajo tudi predstave, ki jih goji neka družba o odrasli in starejši generaciji. Zato v drugem delu članka opišemo tudi, katere družbeno-ekonomske razmere ter institucionalne strukture pogojujejo možnost uresničevanja permanentnega izobraževanja kot naloge prihodnje družbe.
