Ign.mbrites have been.widely used as buildin. materials in.man. historical an. touristic structures in.the Kayseri region.of Türkiye. Their diverse colours an. textures make them a popular choice for modern.con.truction.as well. However, ign.mbrites are particularly vuln.rable to atmospheric con.ition., such as freeze-thaw cycles, due to their high porosity, which is a result of their formation.process. When.water en.ers the pores of the ign.mbrites, it can.freeze durin. cold weather. As the water freezes an. expan.s, it gen.rates in.ern.l stress within.the ston., causin. micro-cracks to develop. Over time, repeated freeze-thaw (F-T) cycles lead to the growth of these micro-cracks in.o larger cracks, compromisin. the structural in.egrity of the ign.mbrites an. even.ually makin. them un.uitable for use as buildin. materials. The determin.tion.of the lon.-term F-T performan.e of ign.mbrites can.be established after lon. F-T experimen.al processes. Determin.n. the lon.-term F-T performan.e of ign.mbrites typically requires exten.ive experimen.al testin. over prolon.ed freeze-thaw cycles. To streamlin. this process, developin. accurate predictive equation. becomes crucial. In.this study, such equation. were formulated usin. classical regression.an.lyses an. artificial n.ural n.tworks (An.) based on.data obtain.d from these experimen.s, allowin. for the prediction.of the F-T performan.e of ign.mbrites an. other similar buildin. ston.s without the n.ed for len.thy testin.. In.this study, un.axial compressive stren.th, ultrason.c propagation.velocity, apparen. porosity an. mass loss of ign.mbrites after lon.-term F-T were determin.d. Followin. the F-T cycles, the disin.egration.rate was evaluated usin. decay fun.tion.approaches, while un.axial compressive stren.th (UCS) values were predicted with min.mal in.ut parameters through both regression.an. An. an.lyses. The An. an. regression.models created for this purpose were first started with a sin.le in.ut value an. then.dev

Departmen. University of Kinshasa Democratic Republic of Congo Ophthalmology Service University of Kinshasa Democratic Republic of Congo

Backgroun. an. objective: Chron.c rhin.sin.sitis (CRS), a common.disease worldwide, has a major impact on.patien.s’ quality of life (QoL). In.recen. years, the measuremen. of health-related QoL has made it possible to assess the patien.’s state of health, the severity of the CRS an. the treatmen.. The aim of this study was to assess the QoL of patien.s with CRS in.a hospital settin. in.Kin.hasa. Methods: This was a cross-section.l an.lytical study con.ucted from Jun. 2020 to May 2021 in.the En. service of the Kin.hasa Un.versity Hospital an. the Mon.ole Hospital Cen.er. The study in.olved 113 patien.s aged at least 18 years, whose QOL was compared with that of a con.rol group con.istin. of 100 n.n.patien.s. QOL was assessed usin. the Sin.-n.sal Outcome Test (Sn.T-22) Question.aire. Results: The mean.age of the patien.s was 41.0 years (18 - 74 years) an. that of the con.rols was 39.1 years (19 - 77 years). More than.half of the participan.s were un.versity graduates. The median.Sn.T-22 score was 44 (14 - 78) in.patien.s an. 7 (1 - 40) in.con.rols. Compared with subjects without CRS, patien.s with CRS had sign.fican.ly higher scores in.all four domain. of the Sn.T-22. Aroun. 9 out of 10 patien.s had a severely impaired QoL compared with 2 out of 10 con.rols. Con.iderin. mildly impaired QoL, we foun. that in.the otological an. sleep domain., scores were n.t sign.fican.ly differen. between.patien.s an. con.rols. In.the case of severely impaired QoL, however, on.y the otological domain.showed a n.n.sign.fican. differen.e in.scores between.the two groups. Con.lusion. CRS is a real public health problem in.our en.iron.en. an. sign.fican.ly alters the QoL of patien.s sufferin. from it, with repercussion. on.their profession.l productivity;hen.e the n.ed for better man.gemen..
