Perceptions And Evaluation Of An Urban Environment For Pedestrian Friendliness: A Case Study, Elizabeth H. Lee Oct 2010

Perceptions And Evaluation Of An Urban Environment For Pedestrian Friendliness: A Case Study, Elizabeth H. Lee

Master's Theses

Public health is an increasingly important issue addressed from both environmental and public health sectors for the future development of urban environments. From a planning perspective, one possible solution is to increase walkability throughout the cities. Many assessment methods are being developed and administered to evaluate the quality of existing urban environments to promote walkable cities/communities. The results from using these methods provide policymakers and stakeholders with valuable information regarding the existing physical conditions of the environment. Although several US cities started to develop and refocus plans toward pedestrian-oriented policies approaches, results from this particular study determined that the quality …


Determination Of Material Emission Signatures By Ptr-Ms And Their Correlations With Odor Assessments By Human Subjects, Kwanghoon Han Apr 2010

Determination Of Material Emission Signatures By Ptr-Ms And Their Correlations With Odor Assessments By Human Subjects, Kwanghoon Han

Kwanghoon Han

The objectives of this study were to determine volatile organic compound (VOC) emission signatures of nine typical building materials by using proton transfer reaction-mass spectrometry (PTR-MS) and to explore the correlation between the PTR-MS measurements and the measurements of acceptability by human subjects. VOC emissions from each material were measured in a 50-l small-scale chamber. Chamber air was sampled by PTR-MS to determine emission signatures. Sorbent tube sampling and TD-GC/MS analysis were also performed to identify the major VOCs emitted and to compare the resulting data with the PTR-MS emission signatures. The data on the acceptability of air quality assessed …
