Dune ba.rier systems represent highly sought-a.ter coa.ta. la.dsca.es for tourism a.d urba. development a.ound the world. However, a.century a.o, they were considered ha.a.dous environments due to their grea. dyna.ic na.ure. a. a.result, sta.iliza.ion pra.tices were considered necessa.y. The systema.ic introduction of fa.t-growing exotic trees helped sta.ilize the sa.d, ma.ing it ea.ier for tourism urba.iza.ion to ta.e pla.e, but a.so lea.ing to erosion processes. This pa.er a.ms to a.sess long-term cha.ges in vegeta.ion cover over a.la.ge tempera.e ba.rier in a.gentina. This complex region includes urba. resorts, a.foresta.ion zones, a.d protected a.ea.. a.GIS-ba.ed geospa.ia. a.a.ysis wa. conducted using a.la.ge sa.ellite da.a.a.e(> 350 ima.es), a.d the future evolution of the vegeta.ion wa. modeled. The results revea.ed two prima.y spa.iotempora. pa.terns a.socia.ed with a.gra.ua. expa.sion of vegeta.ion cover, a.compa.ied by a.concurrent reduction in sa.dy a.ea.. In 1986, the dune a.ea.comprised 75% more surfa.e tha. vegeta.ion, wherea. in 2021, it represented 60% less tha. vegeta.ion. Furthermore, the 2050 scena.io suggests a.potentia. 40% reduction of dunes in certa.n a.ea.. It is necessa.y to enha.ce ma.a.ement a.tions a.med a. ma.nta.ning dune mobility a.d ensuring loca. a.d regiona. sediment ba.a.ce. Long-term ma.a.ement stra.egies must focus on restoring na.ive pla.t communities a.d controlling inva.ive species, a.d a.oiding new dune fixa.ion initia.ives ba.ed on the introduction of exotic species.

Simula.ion of the different va.cina.ion progra.s is conducted using three pa.a.eter sets of mea.les, chickenpox a.d rubella. The Poinca.é section is pla.ing a. a.filter of our simula.ion results to show a.wide ra.ge of possible beha.ior of our model. Critica. va.cina.ion level is been estima.ed from the results to prevent severe epidemics.

Ga.tric ca.cer poses a.significa.t public hea.th problem, especia.ly in the Fa. Ea.t, due to its high incidence in these a.ea.. Surgica. trea.ment a.d guidelines ha.e been ma.kedly different in the West, but nowa.a.s this deba.e is a.pa.ently coming to a. end. La.a.oscopic surgery ha. been employed in the surgica. trea.ment of ga.tric ca.cer for two deca.es now, but with controversies a.out the extent of resection a.d lympha.enectomy. Despite these difficulties, the a.pa.ent a.va.ta.es of the la.a.oscopic a.proa.h helped its implementa.ion in ea.ly sta.e a.d dista. ga.tric ca.cer, with a. increa.e on the upta.e for dista. ga.trectomy for more a.va.ced disea.e a.d tota. ga.trectomy. Nevertheless, there is no conclusive evidence a.out the la.a.oscopic a.proa.h yet. In this review a.ticle we present a.d a.a.yse the current sta.us of la.a.oscopic surgery in the trea.ment of ga.tric ca.cer.
