The purpose of this study is to analyze the acceptance of the On-dol, Korean underfloor heating system, in the official residences built by the japanese colonist in 1905~1945. The On-dol is the main element that formed Korean housing culture throughout our her history. Since the climate of Korea is colder than that of Japan, the Japanese-style house built in Korea needed to take measures for the harsher winter. Therefore the official residences built during the japanese colonial period, built after the Japanese-style house, accepted the On-dol as additional heating system for their houses. Over forty years the official residences were constructed in large quantities, and many of the official residences also installed the On-dol. Some important changes were discovered about the acceptance of the On-dol. To define this concretely, this study was performed empirically through the comparison and analysis of governmental architectural drawings. There is great significance to consider that an architectural element of Korea influenced the Japanese-style houses. In conclusion, differences between the official residences with the On-dol and those without, during the latter stage of the japanese colonial period have founded. These results demonstrate that this element of traditional korean architecture affected the development of foreign houses built in Korea.

This study proposes a method of generating steel house shop drawing in an automated design method, reducing construction manpower and period. With one hour fire-resistant approval code, reflecting work ability and efficiency, steel-framed house market is expected to extend from one or two story house to multi-purpose facilities up to four story height. More models have been constructed in this system than the first appearance of fire-resistant approval in Korea in 1997 Also, cost estimation of components such as frame walls, roof trusses and floors is obtained with shop drawings. Also, the lack of suppliers of steel framed house shop drawing and unstandardized drawing method get constructors have difficulty in understanding its design. In steel framed house industry, shop drawings are essential part in building and constructing framework and they have major effects on construction deadlines and expenses. By exploring method of shop drawing automation, this study aims to optimize work flow with a standardized drawing method. The proposed system can be applied to manufacturing automation in domestic industry of factory-built panelizing method in the near future.

A cabin for Mr. and Mrs. Popenoe of 1922 was designed by the eminent Los Angeles architect, Rudolph M. Schindler. It stands out as an early exemplar of Schindler's most notable work in its unique employment of compositional strategy. Unfortunately, the cabin was demolished before an in-depth research was executed. In addition, there remains no documentary record with regard to the construction process, structural details and the use of materials of the built cabin. However, a set of drawings of the house are housed in the Schindler Archive. Reworking drawings and fabricating a scale model based on the materials obtained from the Archive, this article first depicts the evolution of the design, and then, attempts to investigate underlying principles governing the spatial composition of the cabin.

Recently. our construction industry is using 4D-CAD system but the public Database (DB) for the 4D-CAD system is insufficiently built. It is difficult to connect 4D-CAD system information such as schedule, drawings. Therefore this study suggest a methodology to link the 4D-CAD system information with work breakdown structure(WBS) and the methodology suggested in this study was applied to a 4D-CAD system

Korean railway network GIS-based information system requires so much cost and time. One of the difficulties is due to the fact that GIS-based information system requires the feature database for GIS, which is generally built manually from many as-built drawing files. In order to build-up database automatically Using GPS coordinates, this study suggests the automatic data conversion from electronic drawings to make feature database for GIS. The proposed method can be applied to build large-scale railway facility management system.

The use of drones and laser scanners have the potential to drastically reduce the time and costs of conventional techniques employed for field survey of cultural heritage buildings. Moreover, point cloud data can be utilized to create an as-built Building Information Model (BIM), providing a repository for consistent operations information. However, BIM creation is not a requisite for heritage buildings, and their technological possibilities and barriers have not been documented. This research explored the processes required to convert a heritage university building to a BIM model, using existing off-the-shelf software applications. Point cloud data was gathered from drones for the exterior, while a laser scanner was employed for the interior of the building. The point clouds were preprocessed and used as references for the geometry of the building elements, including walls, slabs, windows, doors, and staircases. The BIM model was subsequently created for the individual elements using existing and custom libraries. The model was used to extract 2D CAD drawings that met the requirements of Korea's heritage preservation specifications. The experiment showed that technical improvements were needed to overcome issues of occlusion, modeling errors due to modeler's subjective judgements and point cloud data cleaning and filtering techniques.

Uigwe is official reports of the Joseon dynasty. They published from early Joseon but remain from 17C. We can search many hidden informations in them. Ga-Jungjagak (temporary T-shaped house) is one of them. It is unique architecture of the Joseon dynasty but it doesn't exist now at all. We can see many drawings describing Ga-Jungjagak (temporary T-shaped house) located next to Jungjagak in Uigwe. Jungjagak (T-shaped house) was built in royal tombs for sacrifice. Ga-Jungjagak was built in royal tombs for sacrifice as Jungjagak but existed temporarily. In this study, I want to find the process of norms Ga-Jungjagak in old records, official reports and annals of the Joseon Dynasty. Results are as follows: Ga-Jungjagak is the sacrifice space for queens in royal tombs. It is need to avoid sacrifice of delight and sorrow at the same time. They sacrifice to represent sorrow after the death of kings and queens for three years. After three year, they sacrifice to represent delight for kings and queens became ancestral gods. Ga-Jungjagak was destroyed three years later to combined sacrifices. The shape of Ga-Jungjagak is similar to Jungjagak in the same tomb. But dimensions of Ga-Jungjagak are equal or smaller than Jungjagak and decorations are abstemious.

There are many types of BOM, such as EBOM, MBOM, As-Built BOM, As-Designed BOM, Generic BOM, Customized BOM, etc. We should define an adequate BOM to achieve some purposes. In this paper, we proposed BOM structure for EMU Maintenance Information System. First of all, we define Master BOM including all part's information, such as 2D/3D drawings, images, specification, etc. And then we define Object BOM that is functional structure for someone to achieve maintenance works. Object BOM will be applied to configure sales orders, explode aggregate forecasts, and calculate standard cost.

The vulnerability of roofing components of contemporary houses built in cyclonic regions of Australia is assessed for increasing wind speeds. The wind loads and the component strengths are treated as random variables with their probability distributions derived from available data, testing, structural analysis and experience. Design details including types of structural components of houses are obtained from surveying houses and analyzing engineering drawings. Wind load statistics on different areas of the roof are obtained by wind tunnel model studies and compared with Australian/New Zealand Standard, AS/NZS 1170.2. Reliability methods are used for calculating the vulnerability of roofing components independently over the roof. Cladding and batten fixings near the windward gable edge are found to experience larger negative pressures than prescribed in AS/NZS 1170.2, and are most vulnerable to failure.
