The Earwitness endeavours to explore the sonic qualities of the city, the spaces that sounds occupy and possibilities of how these spaces can be inhabited. The ability of sound to travel around corners and through walls led to a process of urban exploration within the Pretoria Central Business District that identified a diverse range of ‘inbetween’ spaces that are not traditionally seen as inhabitable. The diversity of these spaces led to the development of an architectural strategy based upon the chair as a spatial device. Its ability to be interpreted on an individual level and employed in the widest range of scenarios makes the chair an ideal candidate to respond to the unique acoustic qualities of the spaces identified. The chair is thus seen as the earwitness to the acoustic qualities of the city and, through a process of transformation and mutation, begins to respond spatially to the personalities of the spaces encountered, taking on mythical personalities of its own. Through occupying the inbetween spaces of the city block, the chairs become a subversive inhabitant of the city – locating spaces that can be listened to. The investigation of the chair as a spatial device is grounded within a sonic festival scenario for the city of Pretoria that aims to re-establish the relationship between the user, sound and the spaces of the city. The festival is operated from a proposed infill typology that completes a more traditionally architectural element to the thesis, whilst maintaining the initial conceptual integrity of the exploration. The process of critical investigation and exploration followed in the thesis aims to reveal methods with which architectural-acoustic installations can promote user engagement with, and awareness, of the city. The Earwitness thus explores the fictions and fragments inherent in the experience of the city through probing the effects of audio culture and architecture. It hosts a set of curious confrontations between the field of the real and imaginary through a collection of quasi-cultural artefacts. These artefacts range from object to installation to event and engage the auditory aspects of the city – questioning the role of design in an immersive world in which freak mutations and mistakes are the norm, perhaps even the key, to success.

This research investigated the need, design, and evaluation of a product capable of providing support to forward-leaning postures. Due to the high occurrence of low-back pain in industry potentially due to workers performing their tasks while assuming forward-leaning postures, along with the biological plausibility of these postures causing low-back pain, the need was established for a product that provides forward-leaning support. An envelope was quantified, ranging from the 5th percentile female to the 95th percentile male, to establish the range of potential forward-leaning postures. The design of a Support-Arm for use with current ergonomic chairs was discussed and design feature specifications were then provided. A Latin Square statistical design was employed to evaluate a Support-Arm model alongside 8 other commonly used chairs over 3 different postures. Subjects, overall, had lower peak pressures for the buttock-thigh region, increased productivity, higher comfort levels, and higher buttock-thigh contact areas when seated in the Support-Arm model chair as compared to the other chairs. Subjects, overall, also ranked this chair first over the other chairs for preferred use after having sitting experience in all 9 chairs. In an additional part of the evaluation, subjects chose their own set-up of the Support-Arm model chair. Eleven of the 18 subjects chose to use the Support-Arm when their workstation was located 36” above the floor. Subjects confirmed the need to design a Support-Arm capable of providing forward leaning support to the entire envelope of forward-leaning postures. Statistical evaluation revealed several significant differences between the chairs. The results gave no indication that the use of a Support-Arm for forward-leaning support may cause detrimental effects to users or overall chair ergonomics. Future research could track workers’ use of a Support-Arm in industry and compare their occurrence of low-back pain to a control group.

The article "Piekara's Chair: Mechanical Model for Atomic Energy Levels" by Zofia Golab-Meyer presents a model of the real-world problem of determining classical energy states suitable for high school or undergraduate college students. This thesis combines this idea with simple geometry to demonstrate how "Piekara's Chair" may be posed and then solved as inverse problems in IR² / Thesis (M.S.)--Wichita State University, College of Liberal Arts and Science, Dept. of Mathematics & Statistics / Includes bibliographical references (leaves 46-47)

The thesis deals with the reconstruction of the café in a historic building on Svoboda Square in Mohelnice. To the revitalized interior, dominated by brick vault was introduced a new and fresh design. The café has two basic spaces. In the first lighter room is located bar and a few tables with long benches and chairs. The back room features a private sitting area overlooking the atrium of the building. Simple shapes and natural materials create contrast with the historic vault. Use indirect lighting is achieved pleasant and intimate atmosphere. An essential element of the interior is a custom made chair that their morphology fit into the concept of the café.
