  • More than 50% of the existing buildings in Korea are over 15 years old. Therefore it is necessary to be held reconstruction or remodeling deteriorated buildings more efficiently. Especially, since remodeling project reserves existing structures, it requires less period of project and construction period compare to reconstruction. It is possible to minimize uncertainty in communication between participants and able to manage information and construct efficiently in remodeling projects. This paper is first step of integrated BIM-based whole lifecyle management of apartment remodeling process. It suggests 3D laser scanner specification factors and site constraint factors for mapping between two groups. Therefore it will contribute to develop mapping algorithm of two groups and find optimal combination for apartment remodeling.

  • In the last five years, 45 people died and 104 were wounded because of carbon monoxide poisoning accident. CO poisoning accident is higher than any other gas accident in the rate of deaths/incidents. Most of these CO poisoning accidents were caused by defective exhaust tube in the old gas boiler and multi-use facility. In this study, the spread of CO gas released from leakage hole of exhaust tube was analyzed by concentration measuring test. CO gas leaked form exhaust tube in a building was highest concentrated near the ceiling. Through these experiments, the reasonable installation location of CO alarm was made certain and suggested.

  • Reconstruction and redevelopment of old and dilapidated apartment and housing have been increasing to provide more housing accommodation and to secure the safety of building structures since the middle of 1990's. Since, however, little researches on the demolition technique have been made, conventional mechanical demolition method were applied to the most of works that resulted in flooding in small demolition companies. Problems associated with mechanical demolition method are increase not only in working days and costs, but also in public claims, particularly for high-rise building structures. This is to contribute the demolition industries bt providing the concept, standards, and technique of demolition engineering while maximizing working efficiency and minimizing public claims.

  • This paper approaches the issue of seismic vulnerability assessment strategies for facade walls of traditional masonry buildings through the development of a methodology and its subsequent application to over 600 building facades from the old building stock of the historic city centre of Coimbra. Using the post-earthquake damage assessment of masonry buildings in L'Aquila, Italy, an analytical function was developed and calibrated to estimate the mean damage grade for masonry facade walls. Having defined the vulnerability function for facade walls, damage scenarios were calculated and subsequently used in the development of an emergency planning tool and in the elaboration of an access route proposal for the case study of the historic city centre of Coimbra. Finally, the methodology was pre-validated through the comparison of a set of results obtained from its application and also resourcing to a widely accepted mechanical method on the description of the out-of-plane behaviour of facade walls.

  • Using ethnographic methods, this study identified the meaning of paternal experience through 1 to 2 hours of individual interviews with the fathers of preschool children. The interviewees were 33 middle-class fathers from 28 to 41 years of age, Twenty had infants under 36 months of age the others had preschool children 37 months of age and older. Results were summed up with two statements : The first is that paternal experience with the under 36-month-old infants can be called "the stage of adjustment". The other statement is that paternal experience with 37-months and older preschool children can be called "the stage of model-building as a father".

  • During the first twenty-six years of its existence from 1954 to 1980, Keimyung University established on its Daemyung Campus a unique community of Western period-style buildings which recalls an old liberal arts college in America. During the first fifteen years, Keimyung built basically in the neo-Georgian style in accordance with the visions of the first two presidents, both of American nationality. During the next eleven years when Keimyung considerably expanded its facilities, it built in the neo-Classical style. The architecture of the Daemyung Campus is not without dynamism as it shows some efforts to integrate the expressions of the historical and the modern, culminating in the Main Library. The Daemyung Campus thus presents an interesting case study of how Western period-style architecture was assimilated in a provincial Korean city with a sense of an on-going building tradition.

  • After 1980's, as economy was rapidly grown and real estate market was active, greatly increased in population has been supplied to the city. Accordingly, national apartment house market is located in the form of Urban Housing Culture. However, as time goes by the apartment houses where the supply of mass became superannuated and residential environment became poor. So, the environment of old apartment houses has been changed to improve with reconstruction. It has been changed in response to the demands of the times. It is one of essential part in a remodeling field for the future although it has some problems in the way that uses existing buildings.

  • Residential building owners are turning toward renovating their existing buildings to improve old and inefficient HVAC systems. Due to the renovation, much of the added costs will inevitably be passed on to tenants by increasing rent rates. This increment often increases the vacancy rate in the buildings. To balance the interests of both owners and tenants, this paper suggested a method to determine an appropriate rental rate increment for the HVAC system renovation. A case study on residential buildings was conducted to determine a balanced point where the rental rate increment that offsets the amount tenants are willing to pay for the renovation. To calculate all costs incurred by the renovation, life-cycle cost analysis was carried out. Therefore, this paper ultimately provides a threshold value of rental rate increment such that building owners can make a reasonable decision on the HVAC system renovation.

  • Till now, the roles of a tradition market were a circulation of the necessities of life, a employment market of local society, a center of community, and a main structure of local economy. Recently, these tradition market is on the decline because it couldn't cope with the internal and external changes. It is recognized that these phenomenon is a factor of economy unbalance. So, to activate the local economy, tradition market should be promoted. Therefore, external changes such as the increase of competition intensity and the changes of consume pattern, internal changes such as the deterioration of facility and old fashioned management were analysed. The activation plan of traditional market were suggested through the decision index for the tradition market in this study.
