Background Safe and healthy learning environment in pre-schools has received increased attention in promoting the well-being of pre-school children. However, pediatric injuries have remained one of the leading causes of childhood morbidity and mortality around the globe. Empowering pre-school teachers with first aid competencies have been identified as being of potential strategy against pediatric health burdens of problem. This study tested the effect of established pediatric first aid training on pre-school teachers’ knowledge, attitude, and intention to practice first aid management to pre-school children in Zanzibar.  Methods Uncontrolled quasi-experimental design with a quantitative research approach was conducted in Teachers’ Resource Centers among 120 preschool teachers at Pemba Island, Zanzibar. First aid training was facilitated based on the prescribed guidelines and standards of materials adapted from the American Academy of Pediatrics and implemented. The intervention was preceded by a baseline assessment using structured questionnaires adopted from previous studies that served as the main data collection tool. Results Participants’ mean age was 32 years ± 6.2 with 84.2% of the sample being females. Given the training, post-test findings demonstrated a significant increase (p < 0.01) in participants’ first aid management scores with mean differences of M = 15.08 ± 5.34 (Knowledge), M = 26.99 ± 6.587 (Attitude), and (M = 4.76 ± 0.648 (Intentional practice). Conclusion The established pediatric first aid training can enhance the spectrum of managing pediatric injuries among preschool teachers in Zanzibar. Ongoing public health services opportunities should be structured within teachers’ continuous learning against pediatric injuries in Zanzibar-Tanzania.

This study included two factors: 1) three irrigation water treatments i) Brackish-water (BW), ii) Magnetic-BW1; brackish water after magnetization through passing a three inch static-magnetic unit produced by Delta Water Company and iii) Magnetic-BW2; brackish water after magnetization through passing a three inch static magnetic unit produced by Magnetic-Technologies Company) and three wheat varieties (Sakha-94, Maser-2 and Gemiza-11). The three irrigation water treatments and the three tested varieties were laid out in split-plot design with three replicates and allocated in the main and sub-plots, respectively under gated pipe irrigations system. The experiments designed at Agricultural Experimental Station of Desert Research Centre, Ras Sidr province, South Sinai Governorate, Egypt. The results indicated that irrigation tested wheat varieties with magnetically treated BW1 or magnetically treated BW2 treatments surpassed irrigation with brackish water in all tested vegetative growth parameters at 75 DAS (i.e., plant height (cm), fresh and dry weight of wheat shoot (kg m 2), water contents (%), Flag leaf area (cm 2 plant-1) as well as shoot contents of N, Mg, Ca, Fe and Cu. While revers trends were recorded in Na, Mn, Zn and proline. Results also, recorded that micromorphological characters as number of cells and thickness of layer in addition to the diameter of vascular bundled especially the xylem vessels were compatible with vegetative growth parameters. The yield crop which is the most important was increased with irrigation by magnetic water. As an average of magnetically BW treatments, the percent of improvement reached to 19.24, 33.97 and 26.99% in grains, straw and biological yield (ton fed-1), respectively compared to irrigation with brackish water. The clear improvement in productivity of tested wheat verities under magnetically treated brackish irrigation water may be due to the reduction of irrigation and/or soil salinity stress as a result of displacement of salts away from the root zone spread, lack of sodium exchange in the soil, availability of most fertilizer elements; increased cations exchange capacity and improved soil aggregation. It be concluded that, application of this technology could be play a vital role for improving wheat productivity when sowing under these conditions.
