This study is aimed to analyze the spatial characteristics of folk house in 360 years historical village “Kolli”, Tongyeong city, and to provide basic materials for the study on the history of house in Korea. The survey was enforced at the July 21-22, 1998 firstly, and was enforced at the August 18-20, 2002 secondly. The major result are as follows; The most folk houses faced of north according to the factors of configuration of the ground and climates. The arrangement of house were laid out freely without definite types. The house form is hipped roof of slate and most ‘一’ shape of 3 bay structure.

The purpose of this study is to present rational methods of multi-criteria optimization of the envelope of buildings. The object is to determine the optimum R-value of the envelope of a building, based on the following criteria: minimum building costs (including the cost of materials and construction) and yearly heating costs. Mathematical model described heat losses and gains in a building during the heating season. It takes into consideration heat losses through wall, roof, floor and windows. Particular attention was paid to have a more detailed description of heat gains due to solar radiation. On the assumption that shape of building is rectangle in order to solve the problem, optimum R-value of the envelope of a building is determined by using non-linear programing methods(Kuhn-Tucker Conditions). The results constitute information for designers on the optimum R-value of a building envelope for energy saving buildings.

For a quick and accurate 3D modelling of a building, laser scanning data, digital maps, aerial photographs and satellite images should be fusioned. Moreover, library establishment according to a standard structure of a building and effective texturing method are required in order to determine the structure of a building. In this study, we made a standard library by categorizing Korean village forms and presented a model that can predict a structure of a building from a shape of the roof on an aerial photo image. We made an ortho image using the high-definition digital image and considerable amount of ground scanning point cloud and mapped this image. These methods enabled a more quick and accurate building modelling.

This paper describes the application of a wireless data acquisition system to monitor wind pressures and velocities with absolute pressure sensors and an anemometer. The system was developed for future deployment, as part of a research effort currently underway to instrument coastal homes in Florida to monitor roof wind pressures during hurricanes. The proposed wireless system will replace the current system that involves a large amount of hardwired connections from the sensors to the data processing unit that requires labor intensive wiring and preparation of the home. The paper describes comparison studies and field tests to assess the performance of the system. The new system offers the advantages of light hardware, ease of installation, capacity for 48 hours of continuous data acquisition, good frequency and amplitude responses, and a relatively simple maintenance. However, the tests also show that the shape of the shell that has been previously used to protect the sensors might interfere with the proper measurement of the pressures.

In part 1, the image common to Jingu′s shrines can be represented as "strict" and "beautiful", regardless of their age. The image changed from gorgeous/orderly to modest/disorderly with times. In part 2, the image was considered on the characters of those architecture′s members and elements. The conclusion is as fellows; 1. The members that strongly influenced on the image of "strict" is a roof with it′s shape and color. 2. The decrease of lightness, yellowness and luster of members changed the image of architecture, from "gorgeous" to "modest". 3. Because of "Sabi" made from "modest", Jingu′s shrines look "beautiful".

The Monte Carlo procedure was used to simulate wind load effects on a light-frame low-rise structure of irregular shape and a main wind force resisting system. Two analytical models were studied: rigid-beam and rigid-plate models. The models assumed that roof diaphragms were rigid beam or rigid plate and shear walls controlled system behavior and failure. The parameters defining wall stiffness, including imperfections, were random and included wall stiffness, wall capacity and yield displacements. The effect of openings was included in the simulation via a set of discrete multipliers with uniform distribution. One and two-story buildings were analyzed and the models can be expanded into multiple-floor structures provided that the assumptions made in this paper are not violated.

Wrinkles and shape distortions are generated during the forming of B-pillar(or center pillar) which is a component of the automobile side-frame. The stretch flanging modes at the joining part of the B-pillar and the roof-rail or the side-still give rise to forming problems when taior-welded blanks are applied to the side-frames. The authors simplified B-pillar lower part to T shaped section to investigate the forming behaviors. Three of die step locations and two of blank types were tested to show the effects of weld line locations and edge conditions on he forming of tailor welded blanks. The heights of body wrinkles and the strain distribution in the stretch flanged area were measured and compared.

This study is to examine the Severe-Ornament (Vyuha :Sanskrit) of wooden pagodas in Shilla period in order to assume a detailed shape of wooden pagodas called the palace style, the multi-story style, the towered namsion style, that were built at the temples in Gyeongju during Shilla period. The Severe-Ornament had been used traditionally by installing a Buddhist image, Guardians, Sarira and by printing a color. The other hand, The roof tiles and tiles were annexed to the Severe-Ornament so as to enhance the value of the wooden pagodas. The Vyuha had been used not only to install a highly valued Buddhist image in the wooden pagodas but also to represent an important part of ritual art of Silla period. Therefore, it was possible to find out a variety of details of the wooden pagodas in Shilla period.

We discovered that each distinct shape of the roof-shaped peaks of (111) facets, which are generated on (110) cross-section of the directly bonded (100) silicon wafer pairs after KOH etching, can be mapped to one of three conditions of the interfacial oxide existing at the bonding interface as follows. That is, thick solid line can be mapped to stabilization, thin solid line to disintegration, and thin broken line to spheroidization. also we confirmed that most of the interfacial oxides of a well-aligned wafer pairs were disintegrated and spheroidized through high-temperature annealing process above 900$^{\circ}$C while the oxide was stabilized persistently when two wafers are bonded rotationally around their common axis perpendicular to the wafer planes.

This paper tries to find out the characteristics of the vernacular dwellings in Noksan area which has been a part of Kaya cultural realm. Through the analyses of its environments and several practical unit plans. The characteristic of the vernacular dwellings in thes arer are as below. The dwellings has been transfigured form [Omaksari] hut which is generally the smallest house form in Korea. The noticeable vernacular hut in this area is smallest 4-kan double-wing plan which is irregular 전 shape, but they call it single wing and 2-kan plan. Leed which can be obtained easily in thes area is used on roof and in wall. Timbers used in constrution are very slim or rather weak, but they were treated carafully. The chimney form in this area seems the results of minimizing of their being from the invasion of Japanese pirate, but also it seems an effective method of heat control. In conclusion, we cannot deny that the house form of this area seems affected by its exclusive natural and social environments.
