Well-designed housing systems are important from the viewpoint of animal welfare and improvement of meat production. In this study, we investigated the effects of outdoor housing of pigs on their behavior, cortisol levels, and meat characteristics. Two groups that were born and raised in a spacious outdoor pen ($4{\times}10$ m for every two sows) or a minimum-sized standard pen in a piggery ($1.9{\times}2.2$ m for every sow) were studied. When their behaviors at the age of 2 to 3 wk were observed, the number of rooting episodes tended to be larger (p = 0.0509) and the total time of rooting tended to be longer (p = 0.0640) in the outdoor-housed piglets although the difference was not significant. Basal salivary cortisol levels of the outdoor piglets at the age of 4 wk were significantly lower than those of the indoor piglets ($5.0{\pm}0.59$ ng/ml vs. $11.6{\pm}0.91$ ng/ml, 30 min after treatment), although their plasma cortisol levels were similar ($53.3{\pm}3.54$ ng/ml vs. $59.9{\pm}4.84$ ng/ml, 30 min after treatment). When the ears were pierced at weaning, plasma and salivary cortisol levels were increased in both groups, even at 15 min after piercing. However, the increase in the outdoor-housed group was significantly less than that in the indoor-housed group. Throughout their lives, body weight and daily gain of the pigs were not significantly different between the two groups. In a meat taste preference test taken by 20 panelists, saltiness, flavor, and color of the outdoor-housed pork were found to be more acceptable. Moreover, when an electronic taste-sensing device was utilized, the C00 and CPA-C00 outputs ($3.78{\pm}0.07$ and $-0.20{\pm}0.023$), which correspond to compounds of bitterness and smells, respectively, were significantly lower in the outdoor-housed pork ($5.03{\pm}0.16$ and $-0.13{\pm}0.009$). Our results demonstrate that the outdoor housing system for piglets induces natural behaviors such as rooting and suppresses the strongest stress reaction of piglets, which could be important for animal welfare. Moreover, the outdoor housing system might change muscle characteristics and improve pork bitterness, flavor, and color. These changes may be preferred by consumers, increasing the sale of these meats.

In this study, considering the difficulties for all farms to convert farm styles to animal welfare-based housing, an experiment was performed to observe the changes in the behavior and welfare of sows when the slat floor was changed to a collective breeding ground. Twenty-eight sows used in this study were between the second and fifth parities to minimize the influence of parity. Using a flats floor cover, the flattening rates were treated as 0%, 20%, 30%, 40%, and 50%. Data collection was the behavior of sows visually observed using a camera (e.g., standing, lying, fighting and excessive biting behaviors, and abnormal behaviors) and the animal welfare level measured through field visits. Lying behavior was found to be higher (p < 0.01) as the flattening rate increased, and sows lying on the slatted cover also increased as the flattening rate increased (p < 0.01). Fighting behavior wasincreased when the flattening rate was increased to 20%, and chewing behavior was increased (p < 0.05) as the flattening rate increased. The animal welfare level of sows, 'good feeding', it was found that all treatment groups for body condition score and water were good at 100 (p < 0.05). 'Good housing' was the maximum value (100) in each treatment group. As the percentage of floor increased, the minimum good housing was increased from 78 in 0% flattening rate to 96 in 50% flattening rate. The maximum (100) 'good health' was achieved in the 0% and 20% flattening rates, and it was 98, 98, and 99 in the 30%, 50%, and 40% flattening rate, respectively. 'Appropriate behavior' score was significantly lower than that of other paremeters, but when the flattening ratio was 0% and 20%, the maximum and minimum values were 10. At 40% and 50%, the maximum values were 39 and 49, respectively, and the minimum values were analyzed as 19 for both 40% and 50%. These results will be used as basic data about sow welfare for farmers to successfully transition to group housing and flat floors.

This study was intended to suggest the design guidelines of the space for the elderly with dementia. To achieve this, the behavioral characteristics of the elderly with dementia were grasped, and the design cases which were considered and reflected of the behavioral characteristics of the elderly with dementia were examined. Then, the effective space design guidelines which met the behavioral characteristcs of the elderly with dementia were suggested. The behaviors of the elderly with dementia were categorized into cognitive, emotional, and functional behavior. The positive influences of space design on dementia symptom were founded in the planned living environments, accessible and visible location of common space such as living room, soft and homelike interior finishes and lighting, and healing garden. Therefore, the space design for the elderly with dementia should be done on the basis of the dementia symptoms and healing effects.

This study measured the thermal environment and residents' control behaviors of cooing according to 3 groups of household type-families with preschool children, families of middle age and families of senior. The object of this study are to fmd the difference of the actual condition of indoor thermal environment and cooling control behavior by age or household type and to develop user oriented climate control system. The results were summarized as follows. When the age of members at household is younger, the indoor mean temperature and temperature that people turned off the air conditioner became lower. These different indoor thermal environment of each group means that younger generation is familiar with cooler from their early age and these early uses of cooler made them prefer cooler condition than family of senior. Therefore, this results show that different indoor thermal environment is influenced by factors such as household type and metabolism difference and so on.

Housing culture has rapidly changed since apartments were first introduced in the 1970's. Among our living spaces, particularly, the kitchen reflects our lifestyle and its changes are more remarkable. Activities in kitchen areas include a diverse range of behaviors such as greeting guests, conversation, and family gathering besides cooking and dining. kitchen areas would not be the dedicated housewives' area, but rather a space for all family members. Kitchen areas become a 'living center' where all family members get together and have various family activity. This housing project was designed for the double income family who is consisted of 4 persons. The total area of Apt was 237.6M2. A residence is always comfortable, resting, and consistent for the family. Intimacy image, functional equipments and space, healthy materials were used for this project.

The purpose of this research is to find applicable design characteristics and methods of communal spaces in vertical urban multi-family housing. With this goal, several overseas' multi-family housing projects are selected and their communal spaces are identified. The design characteristics of the communal spaces are analyzed with a special focus on the territories such as an individual unit boundary, building interior and exterior boundary. In terms of the framework for analysis, territoriality, openness, and unique characteristics are reviewed. As a result, the communal spaces are created using various spatial composition methods such as addition, subtraction, connection, extension, accumulation, and isolation. The communal space programs are integrated in plans and sections throughout the buildings. Visual openness and connection with surrounding urban environments are articulated by void spaces, transparent and translucent building materials, green spaces, and applications of graphical images. Communal identities and aesthetics are emphasized by unique building forms and space arrangements. The uses of finish materials, colors, objects, and images add strong characters to the communal spaces. For a further research, it is necessary to combine a design method study with residents' behaviors and community interactions.

The purpose of this study was to analyze the environmental privacy on the perspective of integration and segregation of spatial areas in facilities for the elderly, through investigating required environmental privacy at each hierarchical space, the contextual situation and counterplan for the privacy. For the study, a content analysis for 35 foreign academic journal articles published from 1990 to August of 2013 was conducted. The results of the study were as follows: First, four hierarchical spaces had somewhat integrated characteristics as being required various types of privacy beyond the original features of each space. Especially semi-public and public spaces were needed the privacy similar to in private or semi-private areas. Second, the contextual situation for the privacy was mainly from undesirable access and psychological pressure of other residents, staff and etc. to the residents' personal space, stuff, and behaviors. The other was from no space (no sitting) or no equipments for privacy. Third, the counterplan for privacy was categorized as improvements of physical environments and making defensible space or keeping physical distance of the elderly. It is suggested that welfare of the aged act in Korea about the room capacity for the elderly facilities needs to be reconsidered for the privacy in their individual rooms and the privacy in semi-public and public area must be considered to make the behavior scope of the elderly extended.

In this study, a mathematical model for analyzing the shifting transients of the passenger car with an automatic transmission is proposed. The proposed model comprises a power transmission system and a vehicle system, which are coupled. In order to extract the modeling parameters, on-road car test is carried out. The model is composed of a detailed powertrain, an engine/AT housing, a simplified suspension system, tires and a vehicle body model. On the test, the vehicle accelerations and pitch ratio are measured by using accelerometers and a gyro sensor. The speeds, the brake signal, and the throttle position are taken from sensors which already exist in the vehicle. Considering natural ftequencies, which is calculated from the measured accelerations, and the characteristic equation, vehicle model parameters are identified. Dynamic behaviors during upshift or downshift are simulated using the proposed vehicle model. By comparing and analyzing the simulation result and on-road car test data, the vibration of the Engine/AT housing influences the shifting transients. The effect of model parameters are also studied. Among model parameters, the location of engine mountings influences the vibration of the vehicle body.

The purpose of this study was to suggest the spatial structure among residential behaviors in relation to work space. To find the structure, Multi-Dimensional Scaling analysis was used. Respondents were 349 middle income housewives living in apartments in the area of Caopital region. Data were collected through the questinnaire survey. For the future residential interior design, following points were sugtested. A laundary space neess to be developed independently , being separated from both bathroom and kitchen/dining space. A new area which will give housewives some territoriality and also function as home office needs to be considered. A space configuration which satisfies the organic relationships among laundary behaviors such as washing dying, ironing and folding , needs to be systematically planned, with two adjoining separate zones of wet and dry utility . The present bathroom nees to be more incorporated to the private bedroom rather than to workspace.
