Korea has experienced many changes since modern hospitals started to be built. Among these changes, interest in 'Promotion of Curing environment', which is the most fundamental one of the hospital functions, has increased more and more. The lobby makes the first impression of a medical building and that is an important function. Recently, the lobby became highly valued not only as a waiting area or a pathway only but as a cultural area. The lobby is considered simply as a complex and busy area because it plays an important role in the building' communications and access systems and has various uses and functions. Based on the concept of curing environment, the lobby can be planned as a facility combining culture and medical functions by applying multi therapy.

This study discusses the features of the lighting and ventilation regulations for residential buildings in Hong Kong. Given the compact built environment and public concerns about the environmental quality of housing, various lighting and ventilation regulations have been enacted in Hong Kong. The application of building regulations on the micro scale and incentive systems on the macro scale are present, and the governments' calls for more active participation of the private sector and use of the building environmental assessment tools were also noted. Unlike South Korea, however, Hong Kong was found to adopt more performance-based standards, consider the external factors of the lighting and ventilation conditions together with the indoor elements, and provide specific design guidelines. Notwithstanding the different climatic conditions and socio-political contexts of Hong Kong and South Korea, these findings provide some policy implications for the South Korean government in its efforts to achieve a healthy environment for high-rise, high-density housing. It is suggested that the South Korean government adopt more on-site measurement methods to reflect the environmental conditions accurately and broaden the scope and scale of the implementation of the lighting and ventilation regulations with more specific, practical planning and design guidelines.

This paper is an outgrowth of many years of practicing real interior work projects and one of my responses to the question not only about the actual dimension of interior work surface but also about the classification of contemporary finishing materials in basic interior project of high-rise apartment houses. For this purpose, 8 conventional apartment units which are already-built or designed have been surveyed and the results are interpreted in the form of proportion of space and finishes. The data can be applied to make up a schematic design in the selection of environment-friendly interior works and assessment of the degree of sustainability. For further study, the basic data provided here can be used as an index to differentiate the occupants' desire toward green interior design for their own apartment spaces, comparing to the conventional interior work in the Korean market. Not surprisingly, wall paper is dominated to make the interior surface in apartment houses. In the percentile of the utilization of finishing materials, wood-flooring and coating materials like wet paint also ranked at the upper position.

The purpose of this study was to discuss how traditional construction practices could be applied to school buildings. The spatial arrangement and constituents of Seoweon and Hyanggyo buildings were analyzed, and the spatial arrangement and ground plans of current schools were analyzed as well. As a result, it's found that how the characteristics of traditional architecture should be reflected in today's school design is one of critical matters that need an immediate attention. Based on the case study, there are some suggestions about the application of traditional construction techniques to school buildings: (1) The link between internal and external spaces should be stressed. The type of spatial configuration the could ensure nature accessibility is required. (2) The use of environment-friendly materials is recommended, and classrooms should be arranged in a way to let them function as multipurpose educational spaces. (3) It's not advisable to construct school buildings according to the sung-Confucianistic construction techniques of traditional educational institutions, but there should evidently be a change in tasteless school buildings, They should be built in small size and in consideration of harmony with nature and ecosystem, and boarding schools should be constructed in a more careful and discreet manner.

The objective of this study was to examine whether a gerotor pump used in a transmission could be converted into an electric vehicle thermal management system pump using a virtual design environment. To achieve this objective, we first built an environment that could analyze the performance of a gerotor pump in heat transfer fluid. Flow rate, pressure, and volumetric efficiency were then analyzed when using heat transfer fluid in a gerotor pump. Finally, how large the displacement volume of the pump should be designed when using a heat transfer fluid other than oil was determined. Based on results of this study, it is expected that gerotor pumps will be applied to new business fields such as electric vehicle cooling systems.

Many of research on noise reduction techniques have been progressed for the improvement of noise environment in subway train. There are many way to noise reduction techniques in the tunnel, but it has been reported as an alternative to attach sound absorption material on tunnel wall. For this reason sound absorption material has been studied for application of tunnel. The objective of this study is to investigate design parameters on a Helmholtz resonator with built-in sound absorption panel for the reduction of the tunnel noise in the subway. Sound absorption panel composed of the perforated panel with sub-millimeter holes and the airspace backed a rigid wall or between panels. The experiment is performed through the change of number of perforated panel, cross sectional area and the depth of airspace of the sound absorption panel under the normal incidence sound.

The study aims to identify the design character of libraries today into outwardness which enhances publicity in the library buildings. This design trend tends to be emphasized in contemporary civic libraries. In these days, the libraries become not only to be the traditional places of information but also to be the multi-purpose places to provide community services and cultural spaces. Thus the contemporary libraries, especially big civic libraries, are willing to open to the public of diverse purposes and to accelerate social communication among them through outward design in the buildings. This study surveys literatures and identify accessibility, symbolism, openness, amenity, connection, as the characters of publicity in the libraries. The study also examines the outward design strategies of the libraries which enhance publicity in the ways of design to connect surrounding environment, to symbolize buildings, to wrap transparent external surfaces and to build interior spaces. The study finds in the case studies of ten outstanding civic libraries abroad which were built in relatively recent years that the outward design is achieved mainly through four ways. First, the libraries have connection with surrounding urban environment, thus have continuities from the surrounding. Second, the libraries have the shapes of landmarks which expose themselves and their roles to the outside. Third, the libraries have transparent surfaces through which outdoor environment penetrates into the buildings. Fourth, the libraries have corridors and halls which look like traditional urban public streets and plazas. The study concludes that outward design strategies which employ in contemporary libraries enhance publicity in the libraries. Thus the libraries can perform as multi-functional cultural and open places which accelerate social interactions among the public of cities. This study has the value as a research which emphasizes outwardness as the design strategies which enhance publicity in contemporary libraries.

The latest UK Climate Projections (UKCP09) show that mean daily temperatures will increase everywhere in the United Kingdom. This will significantly affect the thermal and energy performance of the current building stock. This study examines an institutional fully glazed building and looks into the changes in the cooling loads and thermal comfort of the occupants during the occupied hours of the non-heating period. Furthermore, it investigates the effect of relative humidity (RH) on thermal comfort. The Design Summer Year (DSY) 2003 for London Heathrow has been used as a baseline for this study and the DSY 2050s High Emissions scenario was used to examine the performance of the building under future weather conditions. Results show a 21% increase of the cooling loads between the two examined scenarios. Thermal comfort appears to be slightly improved during the months of May and September and marginally worsen during the summer months. Results of the simulation show that a relative humidity control at 40% can improve the thermal comfort for 53% of the occupied hours. A comparison of the thermal comfort performance during the hottest week of the year, shows that when the relative humidity control is applied thermal comfort performance of the 2050s is similar or better compared to the thermal comfort performance under the baseline.

The purpose of this paper is to estimate effects of healthy city policies on reducing social costs. The analyses were dune at the cities, counties, and communities levels in 2009, and covered Seoul Metropolitan Area(SMA). For estimation of reducing social costs, it developed a system dynamics(SD) model that analyzed causal relationships between physical inactivity rates, the number of deaths, medical expenses, and total social costs. Simulation period of SD was from 2009 to 2030. Three alternatives were proposed with combinations of length of bike lanes, number of bus routes, crime rates, self-reported good health status rates, and obesity rates. The total estimated cost of physical inactivities from 2009 to 2030 was 31.9 trillion won from the future forecast without policies. As a result of simulations with three alternatives, there were economic benefit approximately from 119.7 billion won to 1.16 trillion won. This study contributed to better understanding the economic benefits of healthy cities that were associated with design of built environment and physical activity. It also emphasized the importance of healthy cities planning as one of national welfare polices.

The BIM simulation systems involve inefficient aspects in delivering real world circumstances because they are operated in the virtual reality (VR) environment without representing the job-site operations. Differently from VR, augmented reality (AR) enhances the reflection of job-site reality to virtual environment. AR influences architecture, design and construction. This reality replaces or merges with the normal physical world and it can be tailored to enhance comprehension for specific design and construction activities. The main objective of this research is to develop an AR-based decision support system for free-form buildings design/construction/maintenance processes. Haewoojae, a free-form housing building built in Seoul area is identified as a model building to generate the system. Seventeen engineers, who are masters or doctorate graduate students at the S university in Seoul and have been working in the Korean construction industry for more than 10 years are invited to validate the system's appropriateness and usability in comparison with its development objectives.
