Because of the problem local scour caused by change flow structure water-resistance column bridge pier, theoretical analysis, and indoor water tank test were used to study effect installing a new anti-scouring device in front pier on reduction effect; influence main design parameters such as height protective device, angle distance from was selected, optimal parameter combination selected. The ...

BACKGROUND To evaluate barrier protective properties of Rhinosectan® spray, a medical device containing xyloglucan, on nasal epithelial cells (MucilAir). METHODS MucilAir-Nasal, a three-dimensional organotypic (with different cell types) airway tissue model, was treated with the medical device Rhinosectan® (30 µL) or with controls (Rhinocort-budesonide-or saline solution). The protective barr...

In EARLogs1 #1 and #2 we have demonstrated and discussed the fact that hearing protective devices (HPDs) reduce user sound exposures when properly worn. This means that all sounds may be attenuated, both unwanted sounds (noise) and useful sounds such as speech and warning signals. Thus wearing HPDs may affect speech discrimination, and the perception of warning signals. The magnitude and qualit...

(1) Background: To determine paramedics' frequency of contact with blood and other body fluids, as well as the analysis of knowledge of paramedics about blood-borne infections, their attitudes to patients infected with blood-borne viruses, and the post-exposure procedures implemented by paramedics; (2) Methods: An anonymous questionnaire among 190 paramedics working in various health care facil...

Risk factors for HIV transmission within a hospital setting were assessed using pre-structured questionnaires and observations. Of 409 respondents, 66.3% corresponded to the nursing staff, 14.4% doctors and 8.3% laboratory staff. The irregular use of gloves and other protective clothing for risky tasks, and recapping of needles after use were some of the risk factors identified, especially amon...

Medical devices are responsible for a large portion of nosocomial infections, particularly in critically ill patients. Device-associated infections can cause major medical and economic sequelae. Bacterial colonization of the indwelling device can be a prelude to both infection and malfunction of the device. The pathogenesis of device-associated infection centers around the multifaceted interact...

Carotid artery angioplasty with stenting (CAS) is being performed in many hospitals in Korea. Most of the guidelines which are being used are similar, but the practical aspects such as techniques are different between hospitals. For example, usage of various protective devices, the oral antiplatelet regimen prior to procedure and placing of temporary pacemaker to prevent bradycardia are differe...

Protection in distributed energy systems depends on the operation of a set of coordinated protective devices spread around the power system. Usually these devices encompass some communication skills and can be remotely operated by energy management systems. Despite this interaction readiness, most of them rely only on non-standard communication protocols and some interoperability issues still r...

In this note we describe the standard technical maneuver used in our department to protect the skin during thyroidectomy in order to get the best aesthetic result. We use surgical gloves to protect the skin during these operations to reduce the negative impact of thermal trauma and mechanical retractors and energy delivery devices at the edges of the skin incised. This practice is effective, in...

One of the objectives of the European SUBZERO project was to study the influence of sweat evaporation and condensation on the heat transmission properties of cold protective clothing. With the sweating thermal manikin Coppelius, water vapour transfer through and water condensation in the clothing can be determined simultaneously with the thermal insulation. In this study, 4 cold protective ense...
