Ma.hema.ica. morphology ca. process the bina.y a.d gra.sca.e ima.e successfully. This theory ca.not be extended to the color ima.e directly. In color spa.e, a.vector represents a.pixel, so in order to compa.e vectors, vectoriel orderings must be defined first. This pa.er a.dresses the question of the extension of morphologica. opera.or to the ca.e of color ima.es. The proposed method used the order by bit mixing to repla.e the conditiona. order. Our order is ba.ed on a.combina.ion of reduced a.d bit mixing ordering of the underlying da.a. a.ditiona.ly it is a.tota. ordering. Since it not only solves the problems of fa.se color genera.ed by the ma.gina. order but a.so those of multiple extrema.genera.ed by reduced order. The performa.ce of the introduced opera.ors is illustra.ed by mea.s of different a.plica.ions: color gra.ients for segmenting, ima.e smoothing (noise suppression) by media. filter opera.or a.d La.la.ia. opera.ors. Exa.ples of na.ura. color ima.es a.d synthetic color ima.es a.e given. Experimenta. results show the improvement brought by this new method.

The ma.ic encla.es from Pa.eoproterozoic doma.n a.e considered to be the results of la.ge-sca.e crust-ma.tle intera.tion a.d ma.ma.mixing. In this pa.er, petrogra.hy, minera.ogy a.d geochemistry were jointly used to determine the origin of the ma.ic encla.es a.d their rela.ionship with the host gra.itoids of the Ka. gra.ite-gneiss complex. This study a.so provides new informa.ion on crust-ma.tle intera.tions. The ma.ic encla.es of the Ka. va.y in sha.e a.d size a.d ha.e intermedia.e chemica. compositions. The dia.ra.s used show a.number of simila.ities in the ma.or elements (a.d often in the tra.e elements) between the ma.ic encla.es a.d the host gra.itoids. Geochemica. show tha. the Ka. rock a.e meta.uminous, enriched in silica. medium to high-K ca.c-a.ka.ine I-type gra.ite. The simila.ities reflect a.mixing of ba.ic a.d a.id ma.ma. Ma.ic encla.es ha.e a.typica. ma.ma.ic structure, which is cha.a.terized by ma.ma.mixing. The genesis of these rocks is a.socia.ed with the context of subduction. They result from the mixing of a.ma.ic ma.ma.origina.ing from the ma.tle a.d linked to subduction, a.d a.gra.itic ma.ma.(type I gra.ite) tha. a.ises from the pa.tia. melting of the crust.

Introduction: Ma.dibula. fra.tures in children a.e becoming increa.ingly common. Trea.ment of these fra.tures is difficult due to their a.a.omica. a.d physiologica. complexity. Therefore, there is a.need for well-codified ma.a.ement. Our ma.n a.m wa. to develop a.decision a.gorithm for the ma.a.ement of ma.dibula. fra.tures in children ba.ed on our experience. Ma.eria.s a.d Methods: This wa. a.retrospective descriptive study ca.ried out in the Depa.tment of Stoma.ology a.d Ma.illofa.ia. Surgery a. the University Hospita. of Cocody over a.period of 20 yea.s (2000-2019). Results: We enrolled 58 pa.ients. The mea. a.e of the pa.ients wa. 9.35 ± 2.3 yea.s with a.sex ra.io of 2.22. Tra.fic a.cidents were the ma.n ca.se of ma.dibula. fra.tures (60.35%). Condyla. fra.tures were the most common (46.87%).

We observed 2 ca.es of complica.ions: temporoma.dibula. a.kylosis a.d gingiva. stoma.itis. Conclusion: Ma.dibula. fra.tures a.e common in children. Ma.a.ement is difficult due to a.a.omica. a.d physiologica. peculia.ities. The choice of trea.ment depends on severa. criteria.

Introduction: Medica. trea.ment for POa. is continuous a.d lifelong trea.ment. The a.m of this study wa. to eva.ua.e the rela.ionship between the cost of this trea.ment a.d pa.ients’ income a.d the impa.t of this rela.ionship on trea.ment complia.ce. Ma.eria.s a.d Methods: Prospective cross-sectiona. study with a.descriptive a.m covering sociodemogra.hic da.a. a.era.e incomes, a.d direct a.d indirect costs of trea.ment of 57 pa.ients followed for POa. during the period from Ja.ua.y 1, 2012, to December 31, 2016 (5 yea.s). Results: The pa.ients were a.ed 25 to 77 yea.s (mea. = 54.4 yea.s) with a.ma.e predomina.ce (sex ra.io = 1.5). Retirees were the most represented (26.32%), followed by workers in the informa. sector (14.04%) a.d housewives (12.28%). Pa.ients who ha. a. a.nua. income less tha. or equa. to 900,000 CFa.fra.cs (€1370.83) per yea. represented 56.14% a.d those who did not ha.e hea.th covera.e represented 57.89%. The trea.ment wa. monothera.y (64.91%), dua. thera.y (31.58%) or triple thera.y (3.05%) a.d the a.era.e ra.io of “a.nua. cost of trea.ment to a.nua. income” wa. 0.56 with for ma.imum 2.23 a.d 0.02 a. minimum. Pa.ients who considered the cost of trea.ment unbea.a.le for their income represented 78.95%. Conclusion: Prevention of blindness due to gla.coma.requires ea.ly detection but a.so the esta.lishment of hea.th covera.e mecha.isms to improve complia.ce with medica. trea.ment. In a.dition, considera.ion should be given to the development of gla.coma.surgery in our country, the indica.ion of which could be the first intention in certa.n pa.ients, considering for those pa.ients, the geogra.hica. a.d fina.cia. a.cessibility of medica. trea.ment. .
