Some passenger cars with sunroofs open at tilted positions experience reverse flows into cabin rooms and wind noises much louder compared to other cars. In this study, flows around open sunroofs are numerically studied with the variations of body leakage. The effects of body leakage on ventilation and wind noise of a sun roof are examined, in particular. Furthermore, flow visualization, pressure, and noise measured from wind tunnel and road tests are presented. The results show that too small body leakage results in poor performance of ventilation and generates high wind noise around a sunroof. It is therefore very important to secure an adequate body leakage from the early design stage to achieve better performance of a sunroof as well as passengers' comfort related to HVAC(Heating, Ventilation, and Airconditioning).

While there are a number of guidelines used throughout the world in the assessment of acceptability of tall building accelerations, none are based on systematically conducted surveys of occupant reaction to wind-induced motion. In this study, occupant response data were gathered by both a self-reporting mechanism and by interviewer-conducted surveys in control tower structures over a period of four years. These two approaches were designed in conjunction with experimental psychologists to ensure unbiased reporting. The data allowed analysis of perception thresholds and tolerability at different building frequencies and in different wind climates. The long-term nature of the studies also allowed an investigation of the causes and effects of adaptation to building motion. As the surveys were designed to allow multiple use during single storms, the effects of exposure duration were investigated. A final exit survey was conducted at the primary survey location to investigate views of the acceptability of wind-induced motion and the factors underlying these views. The findings of the field studies indicate that none of the currently used acceleration guidelines address all of the factors that contribute to occupant dissatisfaction. An alternative framework for assessing acceleration acceptability is proposed.

Dynamic vibration absorbers (DVAs) in the form of tuned sloshing dampers (TSDs) and tuned mass dampers (TMDs) are commonly used to reduce the wind-induced motion of high-rise buildings. Full-scale performance of structure-DVA systems must be evaluated during the DVA commissioning process using structural monitoring data. While the random decrement technique (RDT) is sometimes employed to evaluate the DVA performance, it is shown to have no theoretical justification for application to structure-DVA systems, and to produce erroneous results. Subsequently, several practical methods with a sound theoretical basis are presented and illustrated using simulated and real-world data. By monitoring the responses of the structure and DVA simultaneously, it is possible to directly measure the effective damping of the system or perform system identification from which the DVA performance can be evaluated.

This study suggested the environmental components for open space in a healing environment based on the social support approach for integrating and enhancing users' activities and interactions. The physical environments of the open space in healing facilities should be suggested by social support design and support the interactions of various users. Particularly architectural environment conditions should reinforce the contribution to the revitalization of medical facilities based on improving the healing effect of patients through mutual exchange of users. The open space environment conditions influence users' healing process with physical design factors and users' interactions, and the flexible environments based on the social support that is crucial for circulation and mutual exchange of users. The open space transformation, integration of technology, and wayfinding system with color and signage also allow users to improve the space experience and easy access. The environmental components of open space design should include easy access for user inflow, flexible layout for comfort, access to outdoor spaces, integration of warm color schemes for relaxation, personalization of spaces with artwork, and visual interest through the use of textures and materials.

This study investigates the actual hospital-clothes consumption experience of consumers according to gender and age. An all age survey was conducted among male and female ex-patients in Korea nationally. From data collected during April and May 2009, a total of 513 responses were analyzed using descriptive statistics, chi-square analysis, two-way ANOVA, and MANOVA using SPSS 10.1.4. The results are as follows. The hospitalization ratio was higher in the male group than in the female group and increased with age. Many hospitalizations were taken to the department of orthopedics, internal treatment, obstetrics and gynecology, and surgery. The satisfaction with patient gowns was low regarding size, fabric touch, color and pattern, Psychological comfort, and holistic satisfaction, Specifically, the stiffness of the fabric, cheerless colors, and the limited number of sizes were the main complaints; size dissatisfaction was expressed strongly by females. About 35% of respondents showed a positive attitude to wear premium patient gowns. Various medical supplies were used and different items were utilized according to gender and age of patients. Uncomfortableness of medical supplies were highly related to laundry and fabric touch.

This study intends to analyze the various spatial structures and characteristics of the museum based on the two of the Renzo Piano's recent projects Menil Collection '||'&'||' Museum and Beyeler Foundation Museum Which defined the direction of the "Third Generation" in museum architecture with reference to the quality of spatial experience and design applications. Comparison and analysis were done on the basic spatial organization floor layout accessibility exhibition area lighting plan and circulation between the two museum. Through the itemized common characteristics of the museum the architect's proposal on meaning and direction of the new museum architecture can be viewed. The contemporary museums distinguish themselves quite clearly from their predecessors and this applies both to their own form and to their spatial organization. As the public demands and requests toward the museum building facility expand everyday the architect must respond by providing multiple types of space where people can experience different atmosphere in each area. One concept he used to create multi experienced area was manipulation of the natural light using by the state-of-the-art techniques of the light filtering system and multi-layering roof system to protect the valuable collections against the direct sunlight. But mainly it was to prove his strong belief in "architecture of light" by creating space with minimized meaning by purposely distinguished area in order to provide maximum support to the physical value of the collection " The connection with nature" is another concept which Piano used to provide the public a tranquil experience through out the architecture which engages in a lively dialogue with art. In spatial organization Piano concerned on functionality which not only concentrated on the visitor's point of view but also on the museum staff's comfort. Unlkie the traditional museum he alternates various size of exhibition areas for spatial hierarchy. Specially the spatial flexibility that the temporary exhibition areas are able to be expanded to the permanent exhibition areas by adjoining t재 spaces differentiate Piano's new museum from the rest. museum from the rest.

본 연구에서는 제품 이미지에 대한 선호 반응에 있어서 뇌의 반응 패턴의 특징을 파악하고, 피험자가 동일한 대상에 대하여 직관적으로 평가한 선호도 결과와 비교 분석하였다. 첫 번째 실험은 하나씩 별도로 제시된 제품 이미지에 대하여 느끼는 인상을 파악하기 위하여 뇌파 측정을 통한 쾌적도를 산출하였다. 두 번째 실험은 피험자가 모든 제품 이미지를 일시에 비교하며 선호도를 직접 평가하도록 하였다. 첫 번째 실험을 '독립적 인지 반응'이라 하고, 두 번째 실험을 '상대적 인지 반응'이라고 할 때 그 반응의 특성은 다음과 같다. '독립적 인지 반응'에서는 자신의 경험에 의해서 축적된 정보와의 비교에 의하여 절대 가치로서의 감정 상태를 표현하게 되며, '쾌' 또는 '불쾌'라고 하는 감정이 절대적 가치로서 지속된다. '상대적 인지 반응'에서는 이미지를 인지하는 단계에서 비교되는 다른 이미지 정보와의 상대적인 감정 상태를 표현하게 되며, 이때에는 '진정'이나 '흥분'에 해당하는 감정 상태가 상대적 가치로 작용한다.

The purpose of this study was to analyze quantitative and qualitative differences according to shoe type for the grand jete landing in ballet. The subjects for this study were 9 female ballet majors with an average of 12 years of experience. Subjects jumped, performing a front split, and landed on 1 foot, a movement called the grand jete. Analysis was performed on the students' landing. Independent variables were 3 shoe types: split sole, traditional out sole, and 5-toed forefoot shoes, with bare feet as a control group. Dependent variables were vertical passive ground reaction force and qualitative elements. Passive ground reaction force variables(maximum passive peak value, number of passive peaks, passive force-time integral, and center of pressure) were measured by the Kistler 9281B Force Platform. Qualitative elements were comfort, cushioning, pain, and fit. Statistical analysis included both 1-way ANOVA and Tukey's test for follow-up. Finalized data demonstrated that the 5-toed forefoot shoe allows the forefoot to expand and the toes to individually press down upon landing, increasing foot contact with the surface. Five-toed forefoot shoes minimize passive peaks and pain, while increasing comfort, cushioning, and fit. Most ballet movements are composed of jumping, balancing, landing, and spinning. Wearing 5-toed forefoot shoes allows for a natural range of movement in each toe, to improve both technique and balance. Pain and injuries from ballet can be minimized by wearing the correct shoe type. According to this analysis, it is possible to customized ballet shoes to increase the efficiency of techniques and movements.
