Journey to Motherhood in the First Year After Child Birth

Objective: Child bearing is a period of psychological challenges that must be viewed in a social context. This study reports the maternal transition from the perspective of Iranian first-time mothers in the first year after childbirth. Materials and methods: Qualitative method was chosen for explanation of mothers’ individual experiences of motherhood.26 first-time mothers (aged 18-35 years old with various socio-economic status) who had delivered between 0-1 year prior to the interviews participated in the study.Data were collected through in-depth semi-structured interviews and interview transcripts were analyzed using the constant comparison method. Results: The core category was called "Regaining advanced balance." There were several themes within this category: "internal conflicts", "encounter and interaction" and "internalization". They felt unpreparedness, lack of control over their lives, incomplete maternal feelings and unstable relation to their husbands and others. Within the first postpartum days and weeks a sort of attachment develops between mother and child as the mother starts to attain a better understanding of maternal feelings; she begins to accept the child as an independent identity and reconstructs herself. As the attachment to child deepens, the mother feels control over the affairs. She realizes a kind of development and integration in herself which specifically stems from becoming a mother and attempts to strengthen family bonds. Conclusion: Through the expression of new mothers’ experiences toward motherhood, healthcare providers can reach a better perception of the emotional and psychological changes as well as the various aspects of mothers’ acceptance of their maternal role and helps a better preparation and presentation of effective training programs for mothers and families

Prediction and multi-objective optimization of workability and compressive strength of recycled self-consolidating mortar using Taguchi design method

Concrete is the most consumed material in the construction industry. Using recycled aggregates (RA) and silica fume (SF) in concrete and mortar could preserve natural aggregates (NA) and reduce CO2 emissions and construction and demolition waste (C&DW) generation. Optimizing the mixture design based on both fresh and hardened properties of recycled self-consolidating mortar (RSCM) has not been performed. In this study, multi-objective optimization of mechanical properties and workability of RSCM containing SF was performed via Taguchi Design Method (TDM) with four main variables including cement content, W/C ratio, SF content and superplasticizer content at three different levels. SF was used to decrease the environmental pollution caused by cement production as well as compensating the negative effect of RA on the mechanical properties of RSCM. The results revealed that TDM could appropriately predict the workability and compressive strength of RSCM. Also, mixture design containing W/C = 0.39, SF = 6%, cement = 750 kg/m3 and SP = 0.33% was found as the optimum mixture having the highest compressive strength and acceptable workability as well as low cost and environmental concerns

Otologic Problems in Turner Syndrome

Background and Aim: Turner syndrome is the most common sex chromosome abnormality in females, affecting an estimated 3% of all conceiving females. Otologic disease is a common problem in Turner syndrome patients that is due to a combination of small dysfunction Eustachian tube, palatal dysfunction and cochlear malformation.Methods: This study assessed the otologic and audiologic characteristics of a group of Turner syndrome patients. We studied 40 Turner patients aged 10 to 20 years (mean age: 15.84 years, SD=2.67). Pure tone audiometry was carried out for all of them.Results: Forty percent of the patients reported a history of middle ear disease. Analysis of audiometric data in 40 patients tested reveals normal hearing in 47.5%, pure sensorineural hearing loss in 32.5%, pure conductive hearing loss in 17.5% and mixed hearing loss in 2.5% of patients.Conclusion: Careful follow up during early childhood of children with Turner syndrome is necessary to detect middle ear disease and prevent the probable sequel. However, long term periodic follow up is mandatory even after resolution of middle ear disease to detect sensorineural hearing los
