Backgroun.: The most prevalen. n.n.commun.cable disease worldwide is oral health-related disease, with den.al caries an. periodon.al con.ition. bein. common. Oral health status sign.fican.ly impacts overall health an. quality of life. Barriers to den.al care affect children.with special n.eds. This study evaluates the oral health status an. treatmen. requiremen.s of people with special n.eds. Methodology: This descriptive cross-section.l study in.Kumasi, Ghan. examin.d oral health status amon. people, 121 children.with special n.eds over two mon.hs, in.Jun.-July 2022. Den.al caries, periodon.al chan.es, malocclusion. an. trauma were assessed. The data was an.lyzed usin. SPSS 20.0. Results: The oral health status amon. people with special n.eds in.this study was gen.rally moderate, with a ran.e from very good to very poor. The prevalen.e of den.al caries was 37%, with a mean.DMFT score of 2.82. Periodon.al health showed un.atisfactory in.icators such as mobile teeth, poor gin.ival health, high plaque scores, an. the presen.e of halitosis. Con.lusion. This descriptive study aimed to provide baselin. data on.the oral health status of special n.eds studen.s in.Kumasi, addressin. the lack of kn.wledge in.this area. It highlighted the importan.e of den.al care in.main.ain.n. good oral health an. overall well-bein. in.in.ividuals with special n.eds. Coordin.ted efforts by den.al profession.ls are n.eded to provide den.al health education.an. preven.ive in.erven.ion. for these children.

Approximately 2,000,000 people are exposed to volcan.c risks in.commun.ties situated at the flan.s of Moun.s Cameroon.(MC) an. n.iragon.o (Mn. volcan.es in.Cen.ral Africa. This study therefore sought to in.estigate risk perception.from four previous eruption. of MC, n.mely the 1959, 1982, 1999, an. 2000 eruption.;an. two previous eruption. of Mn. 1977 an. 2002. The study was in.tiated with co-design.workshops held with major stakeholders in.the cities of Buea an. Goma at the flan.s of MC an. Mn. respectively, in.2017, to develop the research objectives for the study. A n.n.ran.om question.aire survey was later con.ucted within.14 an. 15 commun.ties in.Buea an. Goma respectively, on.the effects, perceived risks, an. copin. strategies for the chosen.eruption.. Three age groups (18 - 30, 31 - 45 an. >45 years) an. gen.er (male an. female) were con.idered. The population.at the flan.s of both volcan.es cited scien.ific an. in.igen.us factors to be respon.ible for eruption. from these volcan.es. At MC an. Mn. ≥45% of the sampled participan.s (with a higher female population. perceived that the sampled eruption. posed a very high risk to the population. In.terms of the effects, the age group of 18 - 30 was the least kn.wledgeable. In.terms of direct effect on.person., over 90% of participan.s at MC an. Mn.attested that they were overcome by fear/pan.c. On.measures to cope with an. likely eruption. the followin. order was established at the flan.s of both volcan.es: sen.itization.of population. use of religious (prayers) an. of tradition.l/in.igen.us strategies. In.terms of future copin. strategies, while the males at MC main.ain.d sen.itization.as the favourite option. 62% of the males at Mn.opted for tradition.l/in.igen.us strategies. The female population.at both MC an. Mn.showed a higher preferen.e for religious strategies like prayers.

A n.w method for the syn.hesis of azo Schiff an.base ligan. in.which the azo an. azomethin. groups are coordin.tion.sites was developed through a Schiff base precursor. The precursor, n.4-methoxyben.yliden.-3-hydroxyphen.lamin. （SB） derived from 3-amin.phen.l was regioselectively coupled with a diazon.um ion.para to the hydroxyl group of the amin. compon.n. of the Schiff base. The para selectivity was con.rolled by the directin. effect of the hydroxyl group. The ligan. an. its n.ckel（Ⅱ） complex were characterized by elemen.al an.lyses, IR an. UV-Vis spectroscopy. The an.lytical an. spectral data supported the mon.n.clear formulation.of the complex with metal to ligan. ratio （M ： L = 1 ： 2） an. suggested a square plan.r geometry for the complex.
