The purpose of this study is to conduct a comparative analysis between Korea and the United States of the supply process of unit modular housing at both the factory production phase and the transportation and lifting phase, as part of an attempt to invigorate the unit modular housing market in Korea. Unlike the practice in the United States, one of Korea's unique characteristics is that the floor is constructed with reinforced concrete and hot water heating system. To do this, the wet method in Korea is used that includes concrete placement, curing and constructing hot water floor heating system at the factory production phase, which results in a longer production time and also requires the lifting of heavier loads. In the United States, interior and exterior finishing works of modular housing are performed by different companies, and the distance between the unit module factory and the construction site is quite far. This kind of dualized production structure may cause confusion when it comes to schedule management, procurement management, and stock management. Moreover, problems caused by external environmental factors such as wind and rainfall were reported in the course of long-distance transportation. The results of this case comparison are expected to provide fundamental data that will reduce the amount of trial and error in the unit module production, transportation and lifting work in Korea, which has a comparatively small number of unit modular housing cases.

This paper discusses the field testing of two single-span double-tee girder (DTG) bridges in South Dakota to determine live load distribution factors (LLDFs) and the dynamic load allowance (IM). One bridge had seven girders and another had eight girders. The longitudinal girder-to-girder joints of both bridges were deteriorated in a way that water could penetrate and the joint steel members were corroded. A truck traveled across each of the two bridges at five transverse paths. The paths were tested twice with a crawl speed load test and twice with a dynamic load. The LLDFs and IM were determined using strain data measured during the field tests. These results were compared with those determined according to the AASHTO Standard and the AASHTO LRFD specifications. Nearly all the measured LLDFs were below the AASHTO LRFD design LLDFs, with the exception of two instances: 1) An exterior DTG on the seven-girder bridge and 2) An interior DTG on the eight-girder bridge. The LLDFs specified in the AASHTO Standard were conservative compared with the measured LLDFs. It was also found that both AASHTO LRFD and AASHTO Standard specifications were conservative when estimating IM, compared to the field test results for both bridges.

This project addresses the product identification and design application of corrugated products for kinetic architectural applications. Initially, an architectural approach to product identification was carried out with the end goal of demonstrating application design principles of numerous novel architectural examples from the forest products industry. A design and prototyping stage followed demonstrating such application design principles and functional analysis on various novel architectural examples. The results of coupling product identification with proven application advantages will be of potential value not only to architecture but also to other designers in the arts and sciences. The general motivation for the research arises out of a growing interest corrugated and paper products to be ideally suited for various architectural applications for their unparallel environmental benefits. Applications in architecture that use fewer resources and that adapt efficiently to complex and changing conditions are particularly relevant for an industry (architecture) that is increasingly aware of its environmental responsibilities. Corrugated and paper products are highly under-utilized by the building industry as design choice material for both interior and exterior applications. An increased awareness of the benefits of corrugated and paper products coupled with a process of designing for the total use and reuse will prove to be a valuable means by which issues of energy efficiency and environmental quality of buildings could be enhanced to be more efficient, affordable, and therefore reach a broader audience of users.

The purpose of this study is to analyze breast shape by age, to classify breast types and then to suggest brassiere size chart. The subject of anthropometric measurement were 232 women in 20's and 40's. The direct anthropmetric measurement were analyzed by mean, standard deviation, duncan test, T-test, ANOVA, factor & cluster analysis The results are as follows; 1) as a result of analysis for the measurements, according to the increase of age, the items of height were decreased and the items of width, depth, cir- cumference, length were increased, being obesity and breast points were dropped. So the volume and bottom area of 40's women's breast were lager than 20's women's. The width of breast points was bide by increasing of intereior. 2) as a result of factor analyxis, 5 factors were extracted as important factor of breast shapes(obesity of breast and location of breast point, breast height and volume, upper dimensions of breast/lower dimensions of breast, interior dimensions of breast/exterior dimensions of breast, volume of the lower part and drop of breast) 3) as a reslut of cluster analysis, the breast shape were classified into 4 types. namely, typel has the smallest volume, bottom area of breast and the slenderest breast, type2 was the second obesity type. type3 was middle sized type. type4 has much dropped, wide bottom area of breast and the biggest form. 4) To establish brassiere sizing system, the loss funtion was used to decide interval of under bust girth and cup size of size chart. 20 brassiere sizes were established and the size chart covers 92.2% of all subject.

The purpose of this study is to investigate the traditional American houses in eighteen century and their specific styles at the historic pace of Deerfield. The results of this study were as follow: First, Village of Deerfield is founded by Henry Flynt and PVMA(Pocumtuck Valley Memorial Association). Their preservation and restoration has been achieved from the efforts of collection constantly and the concrete research of old houses. So, It should be reflected their way of approach to preserve and restore for old houses in Korea. Second, the traditional eighteen century houses in Deerfield had generally Colonial Style. Style of Colonial houses had a "L"shape exterior view and a flat facade and the front door made a symmetry with sash windows. A chimney had been installed in the middle of the roof and it usually had a gable with natural materials in a simple manner. Third, the most important factor to design houses was a front door and it had been decorated in luxury and in a display. Lastly, the traditional American houses in eighteen century had been greatly influenced not by the that of British which is commonly taken but by the various cultural backgrounds which represented regional characteristics and was rather simple.

The purpose of this study is to investigate the present status of dwelling spaces and deduct sustainable elements in transformation of them by comparing the restored drawings with the surveyed drawings focused on traditional houses that exist in the urban area of cheongju city in Korea. In alteration and extension of these traditional houses, scale of a private room became larger as it has been connected and expanded, the exterior main hall (Daecheong) became the interior living room, and the conventional kitchen was westernized and changed from K type to DK or LDK type. The toilet located at outside was installed by the attached aisle (Toetgan) inside and the existing room. The extension was completed with equipments, storage space, and rental accommodation. The conservative and sustainable elements in the various transformation of them are as follows. Firstly, it was to maintain 3 rooms such as main room (anbang)-main hall (daecheong)-detached room (gunnunbang). Secondly, it was to sustain the circulation of kitchen and arrangement of the - type worktable even though it was westernized. Thirdly, extension of storage space was completed less than 600 mm within the eaves. Although there were functionally and structurally many changes in 18 houses, 4 houses had maintained wooden floor of main hall, 5 houses long planked wooden floor of the attached aisle, and 12 houses rafter ceiling of the main hall and the attached aisle.

This article examines spatial concepts of urban design led by Camillo Sitte (1843-1903) and its influences. Sitte infused the fervor of city planning as an initiator, and his achievements affected Adolf Loos (1870-1933). Thus, this thesis, with regard to Sitte's penchants concerning urban design, focuses on two matters in order to understand Camillo Sitte's efforts to invent a new method on modern city planning and its influence on an architect: first, it deals with his urban studies, theories, and practices on city planning that consider communal living and everyday life and urban typology as well; second, it discusses how his urban ideas are accepted by Adolf Loos. Conclusively, through the investigations on Sitte's movement on city planning and its influence on Adolf Loos, this study clarifies Sitte's efforts to improve urban life and its milieus, and then Loos's efforts to adopt Sitte's criticisms and then re-interpret them in tune with the modern way of living as well. As a result, this thesis shows that they suggested new methods in performing dialectic designs, drawing on the picturesque and modern tradition, although their difference is differentiated from the sense of space, exterior vs. interior, i.e. Raumkunst vs. Raumplan.
