Public concern on the methods of raising food-producing animals has increased, especially in the last two decades, leading to voluntary and mandated changes in the animal production methods. The primary objective of these changes is to improve the welfare of farm animals. The use of gestational stalls is currently a major welfare issue in swine production. Several studies assessed the welfare of alternative housing systems for gestating sows. A comparative study was performed with gestating sows housed in either individual stalls or in groups in a pen with an electronic sow feeder. This review assessed the welfare of each housing system using physiological, behavioral, and reproductive performance criteria. The current review identified clear advantages and disadvantages of each housing system. Individual stall housing allowed each sow to be given an individually tailored diet without competition, but the sows had behavioral restrictions and showed stereotypical behaviors (e.g., bar biting, nosing, palate grinding, etc.). Group-housed sows had increased opportunities to display such behavior (e.g., ability to move around and social interactions); however, a higher prevalence of aggressive behavior, especially first mixing in static group type, caused a negative impact on longevity (more body lesions, scratch and bite injuries, and lameness, especially in subordinate sows). Conclusively, a more segmented and diversified welfare assessment could be beneficial for a precise evaluation of each housing system for sows. Further efforts should be made to reduce aggression-driven injuries and design housing systems (feeding regimen, floor, bedding, etc.) to improve the welfare of group-housed sows.

Presently, there is no legal regulation pertaining to the installation, maintenance, management and operation of fire-fighting facilities in single housing in Korea, relying instead on the awareness of the residents which hopefully will prevent fire. Likewise, accident prevention effort is very limiting and weak. Accordingly, this research examines current situation in which fire results, identifies root causes and studies application of regulations and develop design measures centered on the single housing that is most afflicted with fire. As part of the measure to prevent fire that afflict housing, it is necessary to classify single housing as specific target for fire fighting just like the joint housing among the types of the building structures that are classified according to the usage on the "Appendix Chart I of the Enforcement Ordinance of the Construction Law" for management purpose. Moreover, it is necessary to make the installation of fire-fighting facilities such as simple sprinkler facility for residential area, fire extinguisher, warning system and others for the sake of the senior citizens and disabled people who reside in single housing, mandatory.

The Korean government required the mandatory ratio of public housing including the housing unit for elderly in February 2012 and the number of them is expected to increase accordingly. To prepare for an aged society, these enabling ubiquitous technology will be able to support efficient health care services, which was mentioned in various studies. Therefore, the aim of this study is to draw the design elements for an apartment for providing health care services according to the degree of independence of elderly people and to grasp the current situation and work out tactics by the evaluation of four actual cases. In housing unit in the elderly housing project, design elements supporting amenity improvement was rated to the highest importance, however, in reality, was reflected at lower rate while the risk management plan for public space was applied at the highest rate. Design elements required by new technology such as health monitoring and community management with outside world are still not reflected, however, in order to realize the concept of 'aging in place', health care services in various aspects should be considered in housing planning.

The Korean housing supply have been provided by the Pre-construction sales system. The Pre-construction sales system contributed to large housing supply. But it followed by the market anomaly. Along the housing market is changing to tile market for consumers, it requires new policy and regulations. This market changes and needs to modify the policy make a discussion about introducing the Post-construction sales system. it concerns to change the time to sale. This paper analyzes the present feasibility study and makes a tool to predict construction cashflow considering changed sales point. The sales timing leads to decide the amount of financial costs in the construction project and that cost affects to the feasibility. The accurate cashflow prediction is required for a successful apartment construction delivery.

Aging in place strategies such as residential remodeling have potential to enable older persons to remain in their own homes satisfactorily in terms of quality of life. The purpose of this study is to investigate the types of residential remodeling, needs, and opinions of elderly households living in Seoul and to suggest the housing policy and system for improving independent living of elderly households. Using face to face interview with structured questionnaire, 115 elderly households were interviewed during April $25{\sim}June$ 25, 2005. Most of respondents wanted to stay in their own homes as long as they can and some of them remodeled their houses to adapt their physical and financial conditions and housing needs. Various factors such as financial problem and lack of knowledge about remodeling process, however, restricted their actions to realize their needs. Based on the results, some suggestions to activate 'aging in place' were proposed as future guidelines of housing policy related to residential remodeling for housing welfare of the elderly.

This study was conducted to examine housing preferences among single-person households and to propose guidelines for housing design choices for single people. One hundred and sixty responses to the questionnaire developed by this researcher were analyzed utilizing frequencies, percentages, and t-tests. There were significant differences between single households and non-single households in various aspects of housing preferences. Differences were found in the desired type and size of housing, needed amount of space, and the importance of space itself. Single persons wanted to live in a small apartment, about 83.45$m^2$ (25.29 pyung) size. They consider the bathroom and the master bedroom more important than the living room and kitchen. They prefer to have specifically function-oriented rooms such as shower, home office, computer room, exercise room, or leisure space. Single persons consider information-technological facilities within an apartment very important. They would like to adopt automatic and electronic technology in the house, such as optical communication network, automatic air-cleaning system, and internet TV. Housing preferences differ significantly according to socio-demographic variables such as gender and age. I propose in this study a small-sized, information-, high-tech- and leisure-oriented design that corresponds with the actual housing preferences of the single-person households.

The architecture of the Fuel Thermal Management System (FTMS) in a commercial aircraft engine was built to model and simulate the fuel system. The study shows the thermal interactions between the fuel and engine lubrication oil through the mission profile of a high bypass ratio, two-spool turbofan engine. Fuel temperature was monitored as it flowed through each sub-component of the fuel system during the mission. The heat load in the fuel system strongly depended on the fuel flow rate, and was significantly increased for the periods of cruise and descent with decrease of fuel flow rate, rather than for the periods of take-off. Due to the thermal interaction in the pump housing, the fuel temperature at the outlet of the low-pressure pump was increased (4.0, 9.2, and 30.0) % over the case without thermal interaction for take-off, cruise, and descent, respectively.

In this study, traditional treatment scenario of food wastes that collected and transported food waste is recycled in large treatment facilities and suggested treatment scenario of onsite zero discharge system that food waste is treated in housing complex were supposed. The scenarios were compared and analyzed by capital expenditure, oil consumption, $CO_2$ emission quantity, operating expenditure and management expenses. The capital expenditure, oil consumption and $CO_2$ emission quantity of small scale dispersion dealing method is the lowest compared to traditional treatment method. As a results, it is possible to obtain the effect that operating expenditure was reduced by 91% and management expenses was reduced by 40% with suggested treatment method. The treatment method that have low capital expenditure is tend to lower oil consumption and $CO_2$ emission quantity. The small scale dispersion dealing method have the lowest capital expenditure, oil consumption and $CO_2$ emission quantity and the linked method with sewage treatment have the highest expenditure and $CO_2$ emission quantity. Eventually, the optimal model of onsite zero discharge system in housing complex is small scale dispersion dealing method.
