  • This paper proposes an algorithm for EEG pattern classification using the Multi-template method, which is a kind of speaker adaptation method for speech signal processing. 10-channel EEG signals are collected in various environments. The linear prediction coefficients of the EEGs are extracted as the feature parameter of human sensibility. The human sensibility classification algorithm is developed using neural networks. Using EEGs of comfortable or uncomfortable seats, the proposed algorithm showed about 75% of classification performance in subject-independent test. In the tests using EEG signals according to room temperature and humidity variations, the proposed algorithm showed good performance in tracking of pleasantness changes and the subject-independent tests produced similar performances with subject-dependent ones.

  • Formaldehyde and total volatile organic compounds (TVOC) from building materials have been known as main causes of IAQ problem in Newly-Constructed Multi-Family Houses. Because Multi-Family Houses are built in large quantities in a similar manner, inappropriate selection of building materials and method will detrimental affect IAQ. This research aims to identify major causes of Indoor Air Pollutants in Multi-Family Houses, by constructing Mock-Up & One-Room House. As a result, self leveling concrete, door, and furniture construction is a major cause of indoor formaldehyde increase, and tile bond is TVOC, and urethane water proof is Etylbenzene, and Xylene.

  • Purpose: Tuberculosis(TB) care unit in public health center should be carefully considered to be re-designed as an infection safety environment for both patient and healthcare workers. So, for the enhancement, this study analyses the facility requirements for co-using the screening clinic as a TB and other respiratory disease care unit. Methods: Not only screening clinic facility guidelines from "A Study for Standard Triage Design and Construction Document" but also the guidelines of TB care and related medical facility are reviewed; KDCA, CDC, ECDC and WHO as a TB care, and FGI and NHS for facility. The facility requirements are summarized space, approach, and mechanical requirement in order. By comparing the summary and screening clinic facility guidelines, supplementations are proposed for TB care unit setting. Results: The result of this study shows that both the space program and mechanical requirement of the screening clinic and that of TB care unit are almost identical and could be share, which include direct airflow or negative air pressure in an exam room. To increase functional and economical efficiency, however, it is necessary to consider a multi-functional negative pressured room, So care process may be re-designed based on a room type; face-to-face room or glass wall inbetween. Implications: The facility guidelines for TB care unit of a public health center should be developed to build a safe environment for infection control by reflecting its medical plan and budget.

  • This research paper explores selected behavioral outcomes of a multi-sensory environment. An experimental study was conducted at a specialized facility for the ageing in Sweden. The objective was to explore the effects of agitated behaviors of ageing residents with dementia and to identify any short-term effects. Appointed nursing staff was instructed to record physically and verbally agitated behaviors on three occasions; pre-session, mid-session, and post-session. Over seven months, nine participants received sixty-one sessions in the multi-sensory room. ANOVA and Post hoc multiple comparisons were performed to identify the differences in mean between each session. Generally irritated/frustrated behavior and eating/drinking non foods revealed statistically significant differences, while there were no significant results in verbally agitated behavior. One short-term effect was observed in one agitated category; a reduction of generally irritated/frustrated behavior. These results suggest that the multi-sensory environment can have positive effects on some manifestations of agitated behavior. This study proposes that a multi-sensory environment may be recommended as an alternative intervention for physically agitated behavior among this category of residents. However, more research is needed to understand the specific effects and the best use of the multi-sensory environment for this population.

  • Snoezelen, multi-sensory stimulation, provides stimulation through the visual, aural, tactile, olfactory, gustatory and proprioceptive senses. Its aim is to be a relaxing, feeling of safety, novelty and stimulation with no expectations for performance. Agitated behavior of people with dementia causes significant problems and distress for cares. The objective of this research study was to test the effects of Snoezelen room on physical and verbal agitated behaviors of people with dementia. Four patients participated five sessions in Snoezelen room of 'F' dementia care facility in Sweden. Assessment instrument was basically used Cohen-Mansfield Agitation Inventory-Short Form to be rated by caregivers on a 5-point frequency scale. Pre-trial and post-trial assessments were carried out during $27^{th}$ Aug.-$27^{th}$ Sept. 2007. Result shows that Snoezelen room has some short-term positive effect on agitated behavior even though there was a considerable variation individuals responded. This result adds to the increasing evidence that Snoezelen could be a therapeutic environment for the elderly with dementia. Further research study, with larger number of participation, and a control group is required to establish more scientific evidence of Snoezelen effects on health outcome.

  • The purpose of this study was to explore behaviors of spatial usages such as patterns of spatial usages, perception on residential spaces, and furniture arrangement. A questionnaire survey and interview were adopted in this study, and 146 residents living in apartment with 3 bedrooms, stairway access, and 3-bay style in the City of Gwangju. The major findings of this study were that 1) dining-kitchen (DK) was conceived and used as a space not only for dining but also family gathering and guest reception. Dining table without refrigerator was frequently found in furniture arrangement of DK, and refrigerator has been relocated in utility room facing DK. The results imply the need for social interaction that has been growing. Anbang (master bedroom) has been perceived and used as couples' private area, aside from the traditional function of family interaction. A coordination of both bed and wardrobe out of different furniture arrangements was popular in anbang. Living room was used as a multi-purpose room carrying out various activities such as family gathering, guest reception, and housekeeping. Sofa and cabinet were the most common furniture arrangement in living room. The research results are a basis for development residential open housing system.

  • We carried out three-dimensional flow analysis in a clean room. Flow field in a robot experiment system, induced from the moving robot, is numerically studied in this paper. The effects of moving robot in a clean room are investigated in order to find the section of dust accumulation. Contamination on the bottom produced from the moving robot is predicted from the analysis results from the flow fields. Results show that a large swirl flow is formed around the moving robot. Consequently, the optimal flow condition can be obtained by controlling the fluid velocity through the fixing of inlet or outlet position.

  • This study aims to identify convenient surrounding of the hospital room to be improved by specifically focusing on light environment and to examine a change of inflow of the daylight in the hospital room by using blind and light shelf device as base data of preliminary research for comprehending the relationship between healing environment and natural day light. Simulation analysis on previous facilities and the installation of horizontal light shelf that derives the inflow of day light has been specifically referred by using ECOTECT2011 program. In case of C-facility that mostly adjoined to exterior spaces, it was shown to be closer to a proper uniformity factor when an angle was controlled on the light shelf with blind installed at the same time. However, it was not overall appropriate because of visual displeasure occurred from inflow of much day light. In conclusion, it is the form of flat surface such as H-facility that provides an effect after installing the device to derive day light. Especially, it was shown that interior day light environment was improved when installing blind and controlling the angle at the same time.
