The purpose of this study was to discover who designed the common type and the individual type Goon office buildings in the Japanese colonial period, and to determine how the individual type's space-compositions were compared with the common types. The study used the literature research method. The method used an analysis of the digital images of the Goon office buildings kept in the national archive of Korea, the annotation of the images, the official documents between the Japanese government-general of Korea and To, the employee's registers of the Japanese government-general of Korea, and newspapers or journals from the Japanese colonial period. The designers of the common types were the engineers of the building-construction part in the Japanese government-general of Korea and also those in To. The space-composition of the individual types was similar to and also different from the common types at the same time, and the difference was attributed to the designers' ability and their preferences.

The building structure in Korea is planned to maximize the use of space in recent. The hybrid OCB(Optimized Composite Beam) beam is developed to take advantage of using the space. The OCB beam is composed of the steel H-beam section reinforced by open strands in negative moment zone and the pretensioned PSC concrete section in positive zone. Flexural behavior of typical architectural hybrid OCB beam section was investigated by F.E.M. The 15m, 20m, 30m OCB models were tested on nonlinear material and geometry under static loading system. Following results are obtained from the analysis; 1)The OCB beam develop initial flexural cracking over full service loading. 2)Overall deflections of OCB beam under the service loads are less than those of the allowable limits in KCI Code(2012). 3)The ultimate load capacity get over the nominal strength of the OCB main section. The OCB beam is verified of structural reliability from the finite element analysis.

This study which are recognized that the lack of empirical research about the efficiency of the elements of environmentally friendly housing development planned presented housing design elements and policies to revitalize for the reduction of greenhouse gas emissions by analyzing the effectiveness of reduction of greenhouse gas output. In addition, it used various models of DEA which are accepted until now effective technique to evaluate the performance of the organization. In conclusion, there are effective 5 regionals which are Seoul, Incheon, Ulsan, South Chungcheong Province, South Gyeongsang Province. other regionals was analyzed to be inefficient. The conclusion from this study are as follows: First, in case of 11 regionals which are analyzed to be inefficient, they have to difference plan elements to make up. So each region should establish strategy to complement vulnerability. Second, not only internal architectural factors but institutional, and external environmental factors also affect the reduction of greenhouse gas emissions. And weighted scores also were moderately high. But levels of weighted scores still less than the ratio of Good quality housing. So it can be determined that evaluation of individual architecture still considered important. It need to pay more attention to the operating system and the external environmental factors.

With the current rapid changes in population and technology, the long-lastig housing certification system is a means of prolonging the physical and functional lifespan of a building. The certification requires differentiation between the structure and infill elements to allow for variability and ease of repairs. This works well with prefabricated houses so this study investigated the possibility of applying the long-lastig housing certification requirements to apartment construction using off-site construction (OSC) methods focused on the installation of bathrooms (plumbing and toilet) that differ from the traditional wet method. This study examined three different sized floor plans at 22 m², 46 m², and a combined one resulting in 69 m². The larger 69 m² plan utilized a removeable non-load bearing wall to increase flexibility in the layout of the floorplan. The apartments are constructed of steel reinforced concrete composite columns on a 9 m × 10.5 m grid with integrated slabs. The exterior and interior infill walls are all non-load bearing with some containing plumbing. This separation of the structure and infill walls can help meet some of the criteria in the long-lastig housing certification, particularly with the ease of repairs. Technologies that facilitate the replacement of infill elements that contain plumbing and other building services can benefit the nation by reducing carbon emissions and therefore tax incentives should be introduced to increase the adoption of the proposed construction methods.

This paper proposes a design plan of short-term temporary housing for the victims by disaster. Also construction workability and residential environment evaluated by mock-up. In particular, in the event of a disaster, victims have lived the auditorium or gymnasium of the nearby school which is an emergency shelter. However, there was a problem of livability. Therefore, it is the purpose of study to provide temporary housing that resides within 30 days. For this purpose, a composite panel with light weight and insulation select to produce mock-up. The mock-up complete in about an hour. This is because it is made only of the composite panels. The composite panels confirm to be easy to load and construct. And mock-up evaluates insulation and waterproofing performance in the laboratory. As a result, Mock-up has insulation and waterproofing performance. This suggests an alternative to short -term temporary housing.

In Korea, several design competition have been conducted to revitalize the cultural function of some areas using under-used space. However, though such sites include public and urban assets inherently, these projects defined their boundary as an isolated architectural or landscape design. Hence, this study will clarify the differentiated design content and process for public regeneration of under-used space through analysis of the case-study. For this purpose, firstly, the public and urban assets of under-used space will be analyzed to prove that it should be handled with wider boundaries and perspectives. And then, this study will reveal the limitation of design contents and process of Korean design competitions linking to the regeneration of under-used space after analyzing several case studies. Lastly, some differentiated design inducements conducted by the City of Oslo for the each regeneration plan of under-used space will be deducted, focusing on the fact that those projects have been implemented in more urban and connected ways. As a result, this study is strongly aiming to insist that the revitalization of under-used space should not be implemented by advertising a poetic symbolism. Instead, it must be an practical integrated plan emphasizing the connectivity with surrounding environment and diverse plan.

Urban overcrowding has created an explosive supply and demand for high-rise buildings. High-rise buildings are contributing to enhancing the image of the city by serving as focal points, but due to the stack effect, malfunction of elevator doors, difficulties in opening and closing the doors and windows of the outer wall, smoke and odors spreading to the upper floors, noise, energy loss, fire and pollutants have been causing various unexpected problems such as rapid spread of fire. This study classified high-rise buildings according to their vertical zoning, analyzed the causes of and solutions to the stack effect, and derived design and construction methods. Through the initial plan to block the outside air and securing airtightness through precise construction, we sought ways to secure the airtightness inside and outside the building by actively blocking the airflow from the lower floors. In addition, the facility solution can be a measure to reduce the specific phenomena caused by the stack effect, but it should only be applied to the minimum extent because the potential for secondary damage is high. This study emphasized the need for systematic stack effect management by suggesting design and construction measures for each vertical zoning of the causes and countermeasures of the stack effect. It is expected that this study will be helpful not only for design and construction, but also for building maintenance.
