Abstract: Apatite formation on the surface of materials in body environment is an essential condition to show osteoconduction after implantation in bony defects. This study reports the novel technique for providing the apatite-forming ability to titanium metals by only controlling the spatial gap and thermal oxidation. Two pieces of titanium thermally oxidized at 400 °C were set together like V-letter with varied mouth opening. They showed the formation of apatite on both facing surface after exposure to a simulated body fluid (SBF) proposed by Kokubo and his colleagues, when the gap was less than approximately 600 μm. Moreover, specimens with micro-grooves of 500 μm in depth and 200-1000 μm in width was able to form apatite in SBF with in 7 days, after they were thermally oxidized at 400 oC. These results indicated that the titanium metals were provided with apatite-forming ability, i.e. osteoconduction, due to controlled gap with thermally oxidized surface. Hence, we conclude that bioactive titanium substrate showing osteoconduction can be produced by designed machining followed by thermal oxidation at an appropriate temperature.

Abstract: The paper is aimed at analyzes of environmental stressors in indoor environment such as incorrect spatial arrangement or improper setting of limits and less control of own territory /personal space and diminished choice of body positions. There is emphasized the topic of body positions/postures in standard office working environment whereas more choices of body position is a instrument for reduction of stress and increasing of well–being and chance to get new perspectives, approaches and outputs from human resources as well . Nowadays there is a strong need to incorporate a non-formal working style which is also related to non-formal spatial design that can be then occupied by different body positions and using of space in more dynamic way which we can call dynamisation of space. There are also analyzed its main strategies In the paper there are shown theoretical assumptions of relation between work efficiency, creativity and body working position.There is analyzed process of setting methodology for measuring environmental stress through physiological parameters. It shows results of first experimental tests of biometric responses by different working postures by simulation of standard non-industrial working environment. There we chosen 5 working locations – standard set, dynamic seat, stand, perching and reclining. The paper presents results of the pilot test and shows further perspectives of this research.

Abstract: The city wall ruins park of the old city at Xiaoyi is a ruins park with the city wall as the main body. With the amusement belt formed by the cultural and historical city wall ruins and the moat, and the landscape belt formed by the historical and cultural city block, and also using the design of the space, the water body, the path and the architectural ornaments, the plan focuses on protecting and inheriting the city wall ruins park of the old city at Xiaoyi with the method of protection, restoration, isolation and so on.
