This study analyzes the method for easily constructing a simple space in various environments. It also analyzes cases of modular prefab construction structures and explores various solutions and development directions that can form temporary residential spaces. This research intends to propose the diverse methods and solutions for constructing residential space for users' stable living environment in various unpredictable situations. This study amis to collect and analyze cases of various foreign patents related to the subject. With the analysis on the patents case, the prefab structures are mainly grouped into 4 types of 1) Assembly method using small parts, 2) Prefab module stacking method, 3) Space expansion method, and 4) Production methods of detailed elements. Based on the results, future research will inquire the lower cost and more efficient way of constructing prefab structure.

In the 1970s, increasing penetration of the housing co-housing policy, reconstruction be a great success to improve 1990‘s Old aged apartment's performance. However, in case of reconstruction, it causes the problem such as city environment destruction, resource waste, real-estate speculation etc. With the trend of sustainable construction and resource recycling, remodeling gets more attention than before. In case of country's remodeling, conventional method causes some problems such as delayed construction period and increased cost. Therefore, efforts that obtain economical efficiency are required to power remodeling through use of prefabrication method like PC technology that is useful for reduction effect of construction period, cost and site labor and excellent quality. This research indicates reduceing factor for facilitating prefabrication method and technology selecting framework through specific of Expanding Floor method and remodeling cases to increase the efficiency of remodeling, considers construction parties approaching plan for prefabrication as occasion that powers remodeling.

In this paper, the basic data regarding the application of the MSC (Modular Steel Concrete) beam are presented by comparing the experimental value with the theoretical value, focusing on the bending behavior of the Lip-type MSC beam, which is composed of steel and concrete. Considerable manpower is needed to fabricate the traditional MSC beam, particularly for the tasks of cutting, welding, etc. Because much time is needed to fabricate the traditional SC beam, the prefabrication concept is introduced, easily produce the required size of the SC beam by prefabricating the side module and the lower module, which is made up of a steel sheet. The result indicates that the method of uniting the modules, an d the composition method with concrete, should be improved. The proposed MSC beam can be used as a new structural member by increasing its coherent reinforcement with modules and the composition ratio of steel and concrete through a future study.

The purpose of this study is to provide data for planning future temporary housing in Korea by comparing and analyzing the characteristics of emergency housing rapidly supplied by Japan Prefabricated Construction Suppliers and Manufacturers Association(JPA) and general construction companies, according to the supply subject in times of natural disasters in Japan. Literature reviews and on-site field investigations are conducted as research methods during the period of August 4th~9th, 2019. As subjects of study, the characteristics of two housing complex built in Ishinomaki City with different supply subjects were compared and analyzed. As a result of this study, Japan has a clear distinction of terms for emergency housing, which are divided into rental and construction types. With the close cooperation between the government, local governments and construction companies, providing a prompt systematic supply is possible. The characteristics of emergency housing are differ depending on supply subjects. The emergency housing of JPA has diversity of plane, two rooms facing south, and fast construction time, while the emergency housing of the general construction company has a flexible spatial transformation and excellence of materials.

This study was conducted to apply the modular construction method to Han-ok. The modular method, which is differentiated from the existing one, means a construction method that equipments, windows and interior materials are prefabricated as a six-sided object at a plant and then they are assembled at the least process on the spot. As for the theoretical observation, the theoretical basis to apply the modular method to the modular housing and Hanok was divided into environmental and economic aspect. In order to apply the modular method to Hanok, the unit scale and size were selected and the plane of unit module Hanok was developed. And a standard with regard to the unit combination and material lifting transportation method was set and planned. In addition, through the comparison the unit modular Hanok to the existing Hanok, the difference was analyzed and the strength was identified in terms fo design method, structure, construction method, period and cost. In final, the conclusion, with regard to the economic, technical application in future, was drawn through arranging the study contents. The unit modular Hanok to carry out the high-quality dwelling through construction period reduction, standardized construction materials and improved insulation performance can meet the demands for a paradigm of new construction technology.

The purpose of this study was to study social housing and incubating module planning for the urban regeneration in the deteriorated residential areas. The site of this study is Gwange-ro Gwangmyeong 3-dong, where old residential areas are concentrated, and there are problems in the decreasing number of young people and the aging population and elderly population. In this study, the necessity of supporting housing according to local characteristics and various programs and facilities are proposed, and various alternatives of modular housing are derived. As a result, it proposed verification of local regeneration and activation and orientation of social housing and local regeneration programs using modularity in the future.

In the unit modular construction, the unit module prefabricated in a factory with a high level of accuracy does not fit completely onto the ground-joint junction due to the low accuracy of the ground work. This difference in the level of accuracy can cause diverse problems, such as twisting the upper unit modules and loosening the connection between the module and the footing. On this background, the aim of this study is to develop a technique for adjusting the height of the prefabricated individual footing. To accomplish the aim, a height adjustment method using bolts and nuts is proposed, and a shop drawing and the construction sequence are also presented in this study. The structural safety is verified through a structure simulation. In the future, research will be conducted on a mock-up test of the height adjustment method developed in this study, and an analysis of economic feasibility will be performed in order to verify its constructability and usability.
