Radi specificnih drustveno-politickih i socio- ekonomskih prilika u regiji, problematika udruživanja privatnih sumoposjednika u interesne udruge do sada nije bila predmetom sireg istraživanja. Na osnovi navedenoga 2008. godine pokrenuto je istraživanje stanja privatnog sumoposjeda i formiranja udruga privatnih sumoposjednika u zemljama regije, u kojima se povijesno razvijao podjednak model vlasnistva. U radu su analizirani stavovi privatnih sumoposjednika prema međusobnoj suradnji i udruživanju u cilju boljeg gospodarenja svojim posjedom, sa posebnim naglaskom na izgradnju sumskih cesta u Hrvatskoj, Srbiji i Bosni i Hercegovini. Provedeno istraživanje ukazuje spremnost privatnih sumoposjednika na suradnju u aktivnostima gospodarenja sumoposjedom, te ukazuje na željene usluge koje bi trebale pružiti udruge privatnih sumoposjednika.

BackgroundStride interval persistence, a term used to describe the correlation structure of stride interval time series, is thought to provide insight into neuromotor control, though its exact clinical meaning has not yet been realized. Since human locomotion is shaped by energy efficient movements, it has been hypothesized that stride interval dynamics and energy expenditure may be inherently tied, both having demonstrated similar sensitivities to age, disease, and pace-constrained walking.FindingsThis study tested for correlations between stride interval persistence and measures of energy expenditure including mass-specific gross oxygen consumption per minute (), mass-specific gross oxygen cost per meter (VO2) and heart rate (HR). Metabolic and stride interval data were collected from 30 asymptomatic children who completed one 10-minute walking trial under each of the following conditions: (i) overground walking, (ii) hands-free treadmill walking, and (iii) handrail-supported treadmill walking. Stride interval persistence was not significantly correlated with (p > 0.32), VO2 (p > 0.18) or HR (p > 0.56).ConclusionsNo simple linear dependence exists between stride interval persistence and measures of gross energy expenditure in asymptomatic children when walking overground and on a treadmill.

This research aimed to evaluate the sassafras (Ocotea odorifera) and eucalyptus (Eucalyptus viminalis) essential oils on the control of larvae and adults of lesser mealworm (Alphitobius diaperinus), comparing their insecticide potential. The essential oils were produced through water vapor extraction in a semi industrial scale. Contaminated paper filter technique was applied to evaluate the insect mortality. In the current experiment twelve concentrations were included for evaluation and among them one control (solvent) in order to settle the mortality rate and LC50 of the two tested essential oils. The larvae were more susceptible then the adults to sassafras essential oil exposure and less susceptible than the adults, when exposed to eucalypt essential oil. Larvae as well as adults of A. diaperinus were more susceptible to the sassafras (LC50 adults 0.26mL l-1 and larvae 0.12mL l-1) than the eucalyptus essential oil (LC50 adults 1.37mL l-1 and larvae 1.72mL l-1), by contact intoxication (Ocotea odorifera: Larvae y=3,3916+1,4699logx; Adult y=0,9486+2,8576logx; e Eucaliptus viminalis: Larvae y=1,3643+1,6254logx; Adult y=1,4487+1,6623logx). It is concluded that the essential oils of sassafras and eucalyptus can be used to control lesser mealworm and used as a new integrated strategy for management of this pest.

BackgroundElectrodermal reactions (EDRs) can be attributed to many origins, including spontaneous fluctuations of electrodermal activity (EDA) and stimuli such as deep inspirations, voluntary mental activity and startling events. In fields that use EDA as a measure of psychophysiological state, the fact that EDRs may be elicited from many different stimuli is often ignored. This study attempts to classify observed EDRs as voluntary (i.e., generated from intentional respiratory or mental activity) or involuntary (i.e., generated from startling events or spontaneous electrodermal fluctuations).MethodsEight able-bodied participants were subjected to conditions that would cause a change in EDA: music imagery, startling noises, and deep inspirations. A user-centered cardiorespiratory classifier consisting of 1) an EDR detector, 2) a respiratory filter and 3) a cardiorespiratory filter was developed to automatically detect a participant's EDRs and to classify the origin of their stimulation as voluntary or involuntary.ResultsDetected EDRs were classified with a positive predictive value of 78%, a negative predictive value of 81% and an overall accuracy of 78%. Without the classifier, EDRs could only be correctly attributed as voluntary or involuntary with an accuracy of 50%.ConclusionsThe proposed classifier may enable investigators to form more accurate interpretations of electrodermal activity as a measure of an individual's psychophysiological state.
