This project motivates to develop virtual tools for computer to optimize the heat treatment condition and to support decision for HT operation by knowledge based database in addition to process simulation. As one of the activities with the cooperation of the Society of Materials Science, Japan and the Japan Society for Heat Treatment, a benchmark project is undergoing. This includes simulation of carburized quenching process of a cylinder, disc, and ring as well as a helical gear by use of common data of materials properties and cooling characteristics by several available simulation programs. A part of the newly obtained results is presented as an interim report.展开更多

This cross-sectional study interviewed 150 VHT members and 16 key informants in three districts in Northern Uganda to establish the roles of VHTs, the service gaps encountered and the measures in place to address these gaps. Quantitative data were analyzed using SPSS 16.0. Direct content analysis of themes of transcribed qualitative data was conducted manually for common codes. The majority of the respondents 64.29% (n = 72) reported to have been VHT volunteers for more than 5 years. Among the roles were community mobilization reported by 99.1% (n = 111) and home visiting of individuals reported by 97.3% (n = 109). Lack of transport, motivation, adequate skills and community appreciation with nearly no measures in place to counteract the challenges was reported by almost all respondents. Although the VHT concept can be a significant means of achieving universal access to primary health care, extensive community involvement and motivation of the volunteers are highly needed for a maximum benefit.展开更多
