The study aims to investigate the corrosion of steel in carbonated concrete. The parameters of the specimens are crack Widths and water cement ratio of concrete. The results indicate that the corrosion area of steel increase with increment in the widths of crack. The weight loss is no significant relationship with the crack widths. Although the corrosion depth is large in the position of a crack, there is no influence of crack widths.

Purpose: To study the appropriateness of rabies post-exposure prophylaxis (rPEP) for children with animal bite who visited the emergency department (ED). Methods: The study enrolled children younger than 18 years with animal bite who visited the National Medical Center ED between January 2014 and October 2017. The children’s electronic medical records were retrospectively reviewed. Data for analysis included age, sex, body parts bitten by animals, species of animals, regions where animal bites occurred, history of recent antibiotics therapy and tetanus vaccination, and justification by the 2017 Guidelines for Rabies Control in Korea and implementation of rPEP. In children who underwent unjustified rPEP or did not undergo justified one, we recorded their guardians’ opinion for or against rPEP. Results: Of the 63 enrolled children, rPEP was justified for 38 children by the Korean guidelines. Of the 38 children, 35 actually underwent rPEP. Among the remaining 3 children, 2 did not undergo the prophylaxis as per the guardians’ requests. Among the 25 children whose rPEP was not justified, 8 underwent the prophylaxis. Of these 8 children, 7 did based on the guardians’ requests. Conclusion: In this study, inappropriate rPEP was usually affected by the guardians’ requests, regardless of the criteria for such prophylaxis. Thus, their requests for or against rPEP should be discussed with emergency physicians who are aware of the relevant criteria to prevent occurrence of rabies or unnecessary use of medical resources.

Corrosion of steel in uncarbonated and carbonated concrete was investigated by accelerated exposure tests. The parameters of the specimens were crack width, cover thickness and water to cement ratio of concrete. The resultsindicate that: (1) The corrosion area ratio and the weight loss of steel in uncarbonated concrete increased as the crack width and the water to cement ratio increased; (2) The existence of a crack strongly affected steel corrosion in carbonated concrete, though the effect of crack width became weaker as the degree of carbonation increased, ultimately disappearing; (3) Though the weight loss of steel in carbonated concrete was larger than that in uncarbonated concrete specimens, the corrosion current value was conversely lower in carbonated specimens. It is thought that carbonation of concrete caused microcell corrosion to became larger than macrocell corrosion. As the water to cement ratio increased, this tendency became more evident; (4) As the corrosion area ratio increased, the macrocell ratio, i.e., the percentage of macrocell corrosion to the total corrosion of steel, decreased.
