  • SAFRS(Spontaneous Acoustic Field Reproduction System) is a system to sense changes of surroundings and produce sounds which can go well with environment elements sensed by the system in to the space. The sounds were judged by individual evaluation and, the classification of the preferred sounds according to the mood of the space was suggested in the former study. Effectiveness of SAFRS with field application was validated by prior studies which dealt with researching acoustic environment, evaluating images of sounds, and rating environment with existence and nonexistence of sound resources such as fountains and the system after applied in D university. In this study, for more effective field application of SAFRS, research for the acoustic environment around sound resources and subjective evaluation of the preference of the sounds from the resources were made and it was considered that the results of the experiments should be primary information to propose proper sound level to be offered by the system. The results of the study are as follows; 1) It was considered that the ambience of the center road was dependent upon produced sounds by the system and water sounds of the fountain and that of walk way was mostly dependent upon produced sounds. 2) The results of the subjective evaluation showed that the distance from sound resources was suggestive; the more distant from produced sounds the less full and clear the sounds, the less distant from the sounds of water the more delight and idyllic ambience, and the less distant from the forest the more idyllic ambient and diversity. 3) The results upwards were telling that an average value of six elements for the evaluation was even at the place set back 10.2m from center road and walk way. And harmony of all sounds of the place should be considered to propose suitable sound level of SAFRS.

  • This study aims at analyzing the therapeutic design characteristics implemented in the indoor atriums of the outpatient areas in four children's hospitals in London and San Francisco. A mixed-method approach was used to examine the spatial configurations and design elements in the atriums, while a literature review was conducted to understand the therapeutic design characteristics relevant to atrium spaces and children's healthcare facilities. The spatial design and the pattern of use of the atrium in each hospital were studied during field visits and interviews with the hospital management staff. Based on the literature review and the observations from the field study, a Visibility Graphic Analysis was chosen to examine the visibility, accessibility, and intelligibility of the spatial configurations in the atriums of each hospital. In addition, the openness, restfulness, and vibrant ambience of the design elements in the atriums of each hospital were investigated by surveying fifty-two design professionals on the quality of the design elements in the atriums. A spatial configuration analysis, confirmed that all the atrium spaces had high visibility, accessibility, and intelligibility due to their high connectivity, integration, intelligibility, and because the atriums were laid out in the open lobby space, along the major circulation axis, or in the circulation intersection. In the survey of the design element evaluation, all atriums proved to be appropriate in terms of openness, while the adequacy of restfulness and vibrant ambience differed depending on the hospitals. Notably, location and orientation, access, natural light, outdoor view, and play facilities were found significant environmental design elements determining the successful implementation of the therapeutic design in the atriums. The observations from the aforementioned are further discussed to enhance the therapeutic design quality of atrium spaces in children's hospitals.

  • Biomimetic actuators composed of cellophane with an electrically conducting polyaniline(PANI) film have been fabricated and tested in air ambience conditions doped with two different counter ions such as perchlorate (${ClO_4}^-$) and tetrafluoroborate (${BF_4}^-$). Fabrication of the trilayer CP//CELLOPHANE//CP substantially enhanced the tip displacement (13.2mm) compared to the small displacement (8.3mm) of the bilaye. CP//CELLOPHANE. The ion migration among layers is the main factor behind the expansion of cellophane, while the expansion/contraction of PANI are dependent on the redox reaction of the polymer. The displacement of the composite is dominated by the humidity content. This implies that the actuation principle is possibly due to the assistance of water existing.

  • The effects of gas atmosphere and in-situ thermal annealing in buffet layers on the characteristic of the ZnO grown by RF magnetron sputtering have been investigated. It was shown that the introduction of buffer layers grown at the gas atmospheres of the mixed $Ar/O_2$ and the in-situ thermal treatment of the ZnO buffer layer improved the structural and optical properties. In addition, the ZnO films on the buffer layer thermal-annealed at $N_2$ gas ambience showed the strong emission of the near band gap exciton with narrow linewidth by combining the high-temperature growth of the ZnO film.

  • Time dependent ozone generation characteristics of some oxide layers grown by ozone on the surface of corona discharge wires have been investigated experimentally in air ambience. Four wires of stainless steel, iron, silver and copper were used for the corona discharge wire of an ozone generator. And the effect of the metal oxide layers on ozone generation was studied and the contamination morphology of each layers was characterized. With the SEM images and the EDS spectra, it was found that all the surface of the corona wire were oxidized by the generated ozone and contaminated by airborne particles through the gradient force. As a result, the morphology and the electrical property of metal oxide layer grown on corona wire surface influenced on ozone generation characteristics i.e. discharge mechanisms.
