Severe accidents in nuclear power plants can cause hydrogen-generating chemical reactions, which create the danger of hydrogen combustion and thus threaten containment integrity. For containment analyses, a three-dimensional mechanistic code, GOTHIC-3D has been applied near source compartments to predict whether or not highly reactive gas mixtures can form during an accident with the hydrogen mitigation system working. To assess the code applicability to hydrogen combustion analysis, this paper presents the numerical calculation results of GOTHIC-3D for various hydrogen combustion experiments, including FLAME, LSVCTF, and SNU-2D. In this study, a technical base for the modeling oflarge- and small-scale facilities was introduced through sensitivity studies on cell size and bum modeling parameters. Use of a turbulent bum option of the eddy dissipation concept enabled scale-free applications. Lowering the bum parameter values for the flame thickness and the bum temperature limit resulted in a larger flame velocity. When applied to hydrogen combustion analysis, this study revealed that the GOTHIC-3D code is generally able to predict the combustion phenomena with its default bum modeling parameters for large-scale facilities. However, the code needs further modifications of its bum modeling parameters to be applied to either small-scale facilities or extremely fast transients.

In the process of arranging artificial teeth the simple atracing technique was shown to be more precise and convenient for general use in dental clinic than gothic arch tracing. The simple tracing technique had some advantages over other ones in that they were very useful to check protrusive, lateral and central occlusion of mandible movement, and it was very easy to transfer the oral condition and mandible movements precisely onto the articulator. Also the technique was more effective than when using wax bite in that the functional movement range has shifted to 0.2 - 0.4mm form central occlusion.

The purpose of this study was to find out the correlation between the spirit of the times and the characteristics of each eras fashionable silhouette and clothing in Gothic and Modern Period. Theoretical studies about the spirit of times, and the characteristics of clothing about each times were preceded. The results were as follows: The similarities of spirit of times were 1) emphasis on reason and rationality 2) centralization by christianity in Gothic Period, and modernism theory in Modern Period 3) times of the nobility and the churchman in Gothic, and elite class in Modern era. The similarities of characteristics of clothing were 1) preference of slim body form as the ideal body figure, 2) emphasis on convenience and function for freedom in action, 3) discontinuation of traditional way of clothing attitude, 4) emphasis on straight and simple on the silhouette and design, 5) tendency of eliminating ornaments on clothing.

Fredrick Krause's chair in the Brooklyn Museum of Art (accession no. 87. 19) is a key to the understanding of factory-made, patent furniture, and the Modern Gothic style in the United States. However, research has rarely done for this chair as well as for the designer. Since this piece is incorporating the utility patent, it is a valuable example to understand the nineteenth-century patented furniture. Because of the popularity of Modern Gothic style, the similar style of chairs were often manufactured. This study explores how other examples are related and what the significance of the Brooklyn Museum chair is. The book of Sharon Darling provided especially helpful information about other Krause chairs in Fond du Lac and chair manufactures in Chicago. The interview with John Ebert at Galloway House in Fond du Lac, Wisconsin was especially helpful. Several primary sources proved helpful in researching the chair. The photo archives. of Kimbel and Cabus at the Cooper-Hewitt National Design Museum provides me a key to this research.

Flabby ridges adversely affect the stability of complete dentures. For the management it is suggested that soft tissues reconditioned before making definitive dentures, and modified impression techniques used for the flabby ridges. Also, correct record of centric relation is important in complete dentures. This case of 67-year-old edentulous female patient had atrophied ridges on the mandible and the flabby ridge on the maxilla. Treatment dentures were fabricated using gothic arch tracing method and tissue conditioner. Definitive dentures were made using window opening impression technique, the gothic arch tracing method, and lingualized occlusion. The patient was satisfied with the function and esthetic quality of the new prostheses.
