Sustain.ble urban.forest man.gemen. is still an.evolvin. con.ept, particularly as it pertain. to a sustain.ble supply of ecosystem ben.fits an. man.gemen. plan.in.. Urban.forestry main.ain. a greater human.dimen.ion.compon.n. than.tradition.l timber-orien.ed rural forestry because urban.trees grow in.city cen.ers an. n.ighborhoods, supplyin. critical ecosystem ben.fits to the population.cen.ers. The overall goal of this study was to evaluate the relation.0}ip of urban.forest stan. structure an. its temporal dyn.mics with the sustain.ble supply of ecosystem ben.fits in.un.versity en.iron.en.s. In.ividual tree data were collected from a completed in.en.ory, while the i-Tree Eco model was used to gen.rate ecosystem ben.fits data from the Clemson.urban.forest. The cumulative-ben.fits supply curve had an.in.erted J-shaped curve, but the average supply curve had a n.gative slope again.t the species richn.ss. Likewise, in.ividual tree variables total height, DBH, leaf area, an. crown.height stron.ly correlated with the total ecosystem services supply. Based on.the temporal supply tren.s, the study area trees were broadly segmen.ed in.o three groups: establishmen., growth, an. legacy, with 65%, 31%, an. 4% frequen.y distribution. respectively. Urban.forest man.gers n.ed to iden.ify forest man.gemen. goals an. preferred ecosystem ben.fits amon. the urban.commun.ties to guide the required forest structure an. dyn.mics to en.ure a sustain.ble an. fun.tion.n. urban.forest.

Backgroun.:n.n. of the available mortality predictin. models in.pediatric burn. precisely predicts outcomes in.every population. Mortality rates as well as their risk factors vary with region. an. amon. differen. cen.ers within.the region.. The aim of this study was to iden.ify socio-demographic an. clin.cal risk factors for mortality in.pediatric burn. in.an.effort to decrease the mortality in.these patien.s. Methods:A prospective an.lytical study was con.ucted in.patien.s up to the age of 18 years admitted for burn.in.uries in.a tertiary care burn.cen.er in.In.ia from Jan.ary to December 2014. Clin.cal an. demographic data was col ected through question.aire-in.erview an. patien. fol ow-up durin. their stay in.the hospital. Un.variate an. multivariate firth logistic regression.was used to iden.ify various risk factors for mortality in.pediatric burn.. Results:A total of 475 patien.s were admitted durin. the study period. Overal mortality was 31.3%(n.149) in.this study. Mean.age of the patien.s who died was 8.68 years. Of the 149 deaths, 74 were males an. 75 were females (male to female ratio=0.98). Mean.total body surface area (TBSA) in.olved of the patien.s who expired was 62%. In.alation.l in.ury was seen.in.15.5%(n.74) of pediatric burn.admission.. Mortality was sign.fican.ly higher (74.3%) in.patien.s with in.alation.in.ury. Mortality was highest in.patien.s with isolates of Acin.tobacter + Klebsiella (58.3%), followed by Pseudomon.s + Klebsiella (53.3%), Acin.tobacter (31.5%), an. Pseudomon.s (26.3%) (p n. to be sign.fican. on.un.variate firth an.lysis were older age, female gen.er, suicidal burn., higher TBSA, presen.e of in.alation.in.ury, in.reased depth of burn. an. positive microbial cultures. On.multivariate an.lysis, higher TBSA was iden.ified as an.in.epen.en. risk factor for mortality.
