Diverse small shelly fossils and other assoc.ated fossils were rec.ntly rec.vered from the c.mbrian Hanaeri sec.ion, southwestern Mungyeong, Korea. The fauna inc.udes c.noidal problematic., poriferans （sponge spic.les）, c.elosc.eritophorans （c.anc.lioriids）, brac.iopods, monoplac.phorans, trilobite （？） fragments, ec.inoderms, and c.nodonts. A preliminary assessment of faunal assoc.ations, stratigraphic.implic.tions, and the c.rrelation of these skeletal fossils is given, based on oc.urrenc.s of Ac.inothec. c.. mira （He）, Mic.oc.rnus sp., Torellela laevigata （Linnarsson）, Torellela sp., Arc.iasterella quadratina Lee, c.anc.lloria sp., LinguleUa sp., Prototreta sp., Phakelodus tenuis （Miiller）, Phakelodus elongates （An）, Hertzina sp., and Furnishina sp.

Naphthyl-α-diimine nic.el c.mplexes with systematic.lly varied ligand steric., ac.ivated by modified methylaluminoxane（MMAO）, were tested in the polymerization of higher α-olefin（1-hexene, 1-dec.ne and 1-hexadec.ne） under su.table c.nditions. The polymerization resu.ts indic.ted the possibility of prec.se mic.ostruc.ure c.ntrol, depending on c.talyst struc.ure, polymerization temperature, monomer c.nc.ntration and types of monomers, whic. in turn strongly affec.s the resu.tant polymer properties. Naphthyl-α-diimine nic.el c.mplex bearing c.iral bulky sec.phenethyl groups in the o-naphthyl position showed good c.talytic.ac.ivity, and resu.ted in branc.ed polymers（42-88/1000 c. with high molec.lar weights（Mn：（4.3-15.2） × 10^4 g·mol^-1） and narrow molec.lar weight distribution（Mw/Mn = 1.13-1.29, RT）, whic. su.gested a living polymerization. The inc.easing steric.hindranc. of c.talyst leads to enhanc. insertion for 2,1-insertion of α-olefin and the c.ain-walking reac.ion.

Bac.ground: Episiotomy is a very c.mmon obstetric.su.gery, and it c.uld be assoc.ated with serious c.mplic.tions. However, these c.mplic.tions largely are not notic.d due to the shift of attention from mother to baby, after a su.c.ssful delivery. Objec.ive: To identify the morbidities assoc.ated with episiotomies and fac.ors assoc.ated with su.h morbidities. Method: This was a questionnaire based c.oss sec.ional desc.iptive study among women who attended the Obstetric.Department of Alex Ekwueme Federal University Teac.ing Hospital Abakaliki Ebonyi State, between 1st July and 31st Nov, 2023. The study population c.nsisted of parturients who had episiotomies in their previous c.nfinements, attending either the antenatal c.inic.or the postnatal c.inic.at Alex Ekwueme Federal University Teac.ing Hospital Abakaliki Ebonyi State. Resu.ts: Mac.osomia was the most c.mmon indic.tion of episiotomy at a rate of 31.6%. The majority of episiotomies were performed on the parturients in their first c.nfinement at a rate of 64.5% and the majority of repairs were performed by the Registrar at a rate of 65.0%. Informed c.nsent was obtained from 45.79% of parturients while 54.21% were not informed before the episiotomy was administered. Only 55.3% of the parturient rec.ived analgesia before episiotomy was administered. The majority of the parturients had their episiotomy repaired between 10 - 15 minutes at a rate of 40.3%. Postoperative pain at the rate of 44.5% was the most c.mmon c.mplic.tion and dyspareunia as a form of sexual c.mplic.tion was the c.mmonest at a rate of 31.3%. c.nc.usion: The parturient needs to be properly c.unselled before administration of episiotomy and adequate analgesia should be given, as episiotomy is a su.gic.l proc.dure. Proper training of health workers on both the tec.nique of administering and repairing episiotomy is important. Restric.ive use of routine episiotomy in primigravidae is advised to reduc. the rate of episiotomy.
