Mouth washing after inhalation of corticosteroids is effective for prevention of local adverse effects. We determined the amounts of drug residues remaining on the oropharyngeal mucosa following inhalation of budesonide (BUD) via a Turbuhaler (BUD-TH) (100 microg). Further, we studied the effects of mouth washing on the removal of drug residues by quantification of BUD in expectorated wash solu...

In Korea, there are not detailed analysis data on soil contamination in nuclear power plant(NPP) and suitable treatment criteria of contaminated soils. When the soils of NPP were contaminated, they have been simply collected and kept in radioactive waste building. But contamination of soils in NPP is inevitable and enormous amounts of contaminated soils can be produced during decommissioning. T...

The risk of inadequate hand hygiene in food handling settings is exacerbated when water is limited or unavailable, thereby making washing with soap and water difficult. The SaniTwice method involves application of excess alcohol-based hand sanitizer (ABHS), hand "washing" for 15 s, and thorough cleaning with paper towels while hands are still wet, followed by a standard application of ABHS. Thi...

Excavation followed by landfilling is the most common method for treating soils contaminated by metals. However, as this solution is not sustainable, alternative techniques are required. Chemical soil washing is one such alternative. The aim of this experimental lab-scale study is to develop a remediation and metal recovery method for Cu contaminated sites. The method is based on the washing of...

PURPOSE To examine whether sterile water and brushes are necessary for hand washing before surgery. METHOD Twenty-two operating room nurses were randomly divided into two groups as follows: 11 nurses who used 7.5% povidone iodine (PVI group) and another 11 nurses who used 4% chlorhexidine gluconate (CHG group) to wash their hands using the rubbing method. All the nurses were examined for bact...

This paper presents a simplified threedimensional dynamic model of a horizontal-axis portable washing machine. This model is used to predict the verge of walking instability during the spinning cycle. Next, two novel methods of stabilization are presented. The design-based method reduces the instability and is cost effective. The control-based method eliminates instability and vibrations and is...

A straightforward method is presented to produce catalyst particle-filled carbon nanotubes. Based on capillarity and surface tension, a simple strategy was developed to selectively fill carbon nanotubes with Fe, Co, and Ni species using a two-step method consisting of impregnation and selective washing. By chosing the impregnation and washing solution properly, metal particles are produced excl...
