To serve the objectives of architectural design course, that is, to develop professional worker our country and society keenly need, this study was carried out as a program to ensure the special domain of vocational educational institution. To carry out such an education, a practical curriculum should be developed and according to it education should be effectively accomplished so that the students could find it easy to seek for work on leaving school, and that they could make progress their field.

At first, I have surveyed the definition of the space scheme and the course of its progression, and have systemized the human behaviour classifying the model of behaviour, and finally have analyzed the result with the actual example of scale computation after suggesting the course of application in space construction.

By impproving the educational program of the Department of Architectural Engineering and studying the theory of learning and the applied method necessary for the development of nation and society, we should develop a satisfying course of education to meet the demand and skill in the industralized society for the purpose of cultivating men of baility with great personalities and creative minds. Therefore, this study focused on classifying several kinds of occupations in the prart of architectured related to what graduates from the department of Architectural Engineering go with into the society. Accordingly after choosing some works adequate to each occupation by the proposed curricula, we tried to establish the scope of education and courses corresponding to the jobs and thus and develop a satisfying curriculum.

Gangliosides are a family of sialic acid-containing glycosphingolipids that are abundant in neurons and have a variety of functions in developing and mature tissues. We examined the expression of ganglioside GT1b in the embryonic preimplantation stage after freezing and thawing processes to determine the regulatory roles of ganglioside GT1b in early embryonic development. ICR mouse embryos at the two-cell stage obtained by flushing the oviducts were frozen by two cryopreservation procedures, slow freezing using a programmable freezer or vitrification by direct plunging into liquid nitrogen. Slow freezing was conducted with equilibration in 1.5 M 1,2-propanediol or 5% equilibration glycerol. Vitrification was applied with a 10-15 min equilibration in 7.5% ethylene glycol (EG), 7.5% dimethylsulfoxide (DMSO), and 30 sec in a solution of 15% EG, 15% EMSO and 0.5 M sucrose. Immediately after thawing, the survival rate of the embryos was assessed by their morphology and ability to develop to blastocysts in culture. The survival rate of vitrified and thawed embryos (92%) was significantly higher than that of slow frozen and thawed embryos (76%) (P<0.05). A tendency of higher blastocyst rate was found in the vitrified and thawed embryos compared to that of the slow frozen and thawed embryos. Confocal immunofluorescence staining confirmed that surviving embryos expressed ganglioside GT1b, with the strongest expression at the compacted eight-cell or later stage embryos. Ganglioside GT1b was not observed in the TUNEL-positive, apoptotic embryos, suggesting that cryopreservation had induced DNA breaks in them. These results suggest that ganglioside GT1b may play an important role in embryo survival or development.

Photochemical reactions of saccharin with tertiary amines were explored. Saccharin was found to undergo an acid-base reaction with N-trimethylsilylmethyl-N,N-diethyl amine to form N-trimethylsilylmethyl-N,N-diethyl ammonium saccharin salt which is in equilibrium with free saccharin and N-trimethylsilylmethyl-N,N-diethyl amine insolution. Photoreaction of N-trimethylsilylmethyl-N,N-diethyl ammonium saccharin in $CH_3OH\;or\;CH_3CN$ results in the generation of desilylmethylated product, N,N-diethyl ammonium saccharin mainly along with benzamide. Photoreaction of N-methylsaccharin with N-trimethylsilylmethyl-N,N-diethyl amine in $CH_3OH$ leads to the production of o-(N-methylcarbamoyl)-N-ethylbenzenesulfonamid e as the major product along with N-methylbenzamide as the minor product. On the other hand, photoreaction of N,N,N-triethyl ammonium saccharin, generated from saccharin and triethylamine, produces N-methylbenzamide as the exclusive product. These photoreactions are quenched by oxygen indicating that triplets of saccharin and N-methylsaccharin are the reactive excited states. Based on the consideration of the redox potentials of saccharin and N-trimethylsilylmethyl-N,N-diethyl amine, and the nature of photoproducts, pathways involving initial triplet state single electron transfer are proposed for photoreactions of the saccharins with the ${\alpha}$-silylamine.
Category Spanning and Audience Consensus on Audience Appeal

This study sought to advance previous studies on the effect of category membership on audience appeal. Previous research has shown that a distinct market identity of a product benefits its performance. A product with a membership across multiple categories performs poorly since it confuses audience for evaluation, lowering its audience appeal. Recent studies have refined previous literature by showing that the degree of category contrast, not simply the number of categories, matters for audience appeal. However, those studies measured the degree of category contrast at the level of a category (e.g., a high contrast category versus a low contrast one). When audiences evaluate a film, however, they seek to identify a category of a film as a whole (e.g., a comedy-horror film). Thus, using the Korean film industry data, we presented a measure of audience consensus on categorizing a film to examine how diverse audiences identify an overall category of a film coherently. A film’s low score in this measure indicat es that the audiences have difficulties categorizing it, lowering its audience appeal. We also sought to go a step further by analyzing interaction between the number of categories and audience consensus on two types of audience appeal, the number of critical reviews and ticket sales. We demonstrated that the number of categories negatively affects audience appeal, but its effect is contingent on how coherently audiences perceive overall categorization of a product.

Photochemical reactions of aromatic carbonyl compounds with silyl ketene acetals have been explored. Irradiation of acetonitrile or benzene solutions containing aryl aldehydes or ketones in the presence of silyl ketene acetals is observed to promo te formation of ${\beta}-hydroxyester$, 2,2-dioxyoxetane and 3,3-dioxyoxetane products. The ratios of these photoproducts, which arise by competitive single electron transfer (SET) and classical Paterno-Buchi mechanistic pathways, is found to be dependent on the degree of methyl-substitution on the vinyl moieties of the ketene acetals in a manner which reflects expected alkyl substituent effects on the oxidation potentials of these electron rich donors. An analysis of the product distribution arising by irradiation of a solution containing butyrophenone (6) and the silyl ketene acetal 9, derived from methyl isobutyrate, provides an estimate of the rate constants for the competitive Norrish type Ⅱ, SET and Paterno-Buchi processes occuring. Finally, sequences involving silyl ketene acetal-aryl aldehyde or ketone photoaddition followed by 2,2-dioxyoxetane hydrolysis represent useful procedures for Claisen-condensation type, ${\beta}-hydroxyester$ synthesis.

Photochemical reactions of saccharin with tertiary amines were explored. Saccharin was found to undergo an acid-base reaction with N-trimethylsilylmethyl-N, N-diethyl amine to form N-trimethylsilylmethyl-N, N-diethyl ammonium saccharin salt which is in equilibrium wit free saccharin and N-trimethylsilymethyl-N, N-diethyl amine in solution. Photoreaction of N-trimethylsilymethy-N, N-diethyl ammonium sacchrin in CH₃OH or CH₃CN result in the generation of desilylmethylated product N, N-diethyl ammonium sacchrin mainly along with benzamide. Photoreaction of N-methylsaccharin with N-trimethylsilymethyl-N, N-diethyl amine in CH₃OH leads to the production of o-(N-methykcarbamoyl)-N-ethylbenzenesulfonamide as the major product along with N-methylbenzamide as the minor product. On the other hand, photoreaction of N, N, N-triethyl ammonium saccharin, generated from saccharin and triethylamine, produces N-methylbenzamide as the exclusive product. These photoreactions are quenched by oxygen indicating redox potentials of saccharin and N-trimethylsilymethyl-N, N-diethyl amine, and the nature of photoproducts, pathways involving initial triplet state single electron transfer are proposed for photoreactions of the saccharins with the α-silyamine.
