The characters' voices in the movie, Rashomon mean the absence of memories created by self-consciousness in order to avoid the crisis. The varying statements of the characters and the three spaces: the space of Nakanimon (th e ruins), the representation space as polyphony (the forest), the egoistic space of truth (the guardian), show the social ills of doubtfulness and mistrust among the Japanese at that time due to the defeat from the war. This matches with the polyphony theory of Mr. Bakhtin, a Russian cultural critic. The key concept of polyphony theory is that the voices that do not accord each other are not harmonized but each voice builds their own world and participates in the novel without being influenced by the creator. This study's aim is to discuss two aspects; Bakhtin's polypony theory allows polyphony film s to function as cinematic composition and spatial characteristics of polyphony films in the movie, Rashomon.

Guillaume Apolinaire and Filippo Marinetti who are pioneers of the early 20 century in point of breaking traditional typographic rules and making particular typographic communication styles,have considered as the same categorytypoillustration or pictorial typography-in other studies evenif they have' particular differences. Their chromcal and theoretical background, works, exPressive materials and methods and the values were analyzed through thesis, books, periodicals and internet materials, and researched the characteristics. There are clear differences in the view of arranging type; expressive materials, sentence struction, layout. The most important differences are concrete expression by Apolinaire and abstract expression by Marinetti . These differences and characteristics made the base of Dada typography and the concrete typogaphers as Bradbury Thompson and Herb Lubalin were influenced by Apolinaire, abstract typographers as Piet Zwart and Neville Brody were influenced by Marinetti.

폴리우레탄 미세포 포움의 가공에 대한 연구를 수행하였으며 기체 과포화 수지 내 의 핵생성율을 증진시키기 위하여 폴리올과 이소시아네이트의 혼합물에 초음파 가진을 적용 하였다. 미세포 구조는 고압에서 질소 가스로 폴리올을 과포화ㅣ키고 폴리우레탄의 두 성분 을 충돌혼합시킨 직후 초음파에 의해 기포를 생성시켜 이루어진다. 낮은 포화 압력에서 질 소에 의해 포화된수지의 핵생성율을 증가시키기위하여 초음파 가진을 적용하였다. 확산에 의해 기포의 성장이 조절된다고 가정하고 금형이 충전되는 동안에 금형 내부에서의 기포성 장기구를 이해하기 위하여 수치적인 방법으로 이론적 연구를 수행하였다. 경화 시간과 확산 경계를 고려하여 최종적인 기포의 크기를 계산하였으며 반응속도론을 고려하여 중합반응 동 안의 폴리우레탄의 점도의 변화를 예측하고 경화 시간을 결정하였다. 이론적 및 실험적으로 결정된 기포의 수를 기준으로 하여 확산 경계를 예측하였다.

단열용도의 폴리우레탄 미세포 포움의 가공에 대한 연구를 수행하였다. 미세포 구조 를 얻기 위해서는 핵생성율을 증진시키고 균일한 분포의 기포를 생성시켜야 한다. 이를 위 해 이산화탄소 기체를 풀리올과 이소시아네이트에 각각 과포화시키고 충돌혼합하여 초음파 가진을 적용하였다. 이산화탄소 기체가 수지 내부에서 기포 내부로 확산함에 따라 기포의 성장이 조절된다고 가정하고 금형이 충전되는 동안에 금형 내부에서의 기포성장기구를 이해 하기 위하여 수치적인 방법으로 이론적 연구를 수행하였다. 경화 시간과 확산 경계를 고려 하여 최종적인 기포의 크기를 계산하였으며 반응속도론을 고려하여 중합반응동안의 폴리우 레탄의 점도의 변화를 예측하고 경화 시간을 결정하였다. 실험적으로 결정된 기체 분자수를 기준으로 하여 이론적으로 확산경계를 예측하였다. 화학적 발포제인 물과 함께 물리적 발포 제인 이산화탄소를 각각 1,2,3기압의 포화압력으로 변화시키면서 폴리올과 이소시아네이트에 포화시켜 폴리우레탄 포움을 제작하고 제작된 포움의 밀도, 열전도도, 및 기포의 수와 지름 을 측정하였다. 측정된 결과로부터 이산화탄소의 포화압력과 초음파 가진이 포움의 기포핵 생성에 미치는 영향을 살펴보았다.

We investigated the effect of grape-must temperature ($50^{\circ}C$, $60^{\circ}C$, and $70^{\circ}C$) on wine quality. We used Muscat Bailey A (MBA) grapes; these are often used in wine making in Korea. The numbers of viable bacteria, yeasts and molds in grape-must decreased with an increase in temperature. Polyphenol oxidase activities in grape-must were reduced at high temperatures. Redness; and, total anthocyanin, polyphenol, and tannin contents of MBA grape wine were higher after heating at $70^{\circ}C$ than after use of lower temperatures. Antioxidant activity was also enhanced after exposure to high temperatures, which may be attributable to the presence of increased levels of polyphenolic compounds in the grape-must. Thus, the heat treatment to prepare grape-must before wine fermentation greatly affects wine quality.

Polyphenols are naturally occurring antioxidants and play many important roles in human health. Grape leaves have not yet been reported to contain the antioxidants. In this study, the physicochemical properties of powders from young grape leaves, obtained after hot-air or vacuum freeze drying, were analyzed. Weight loss rangedfrom 76-80%, but no difference was found between samples prepared by hot-air orvacuum freeze drying. The L-, a-, and b- values of grape powder all fell upon hot-air drying. Quercetin, resveratrol, catechin, and epicatechin were detected in all cultivars. The contents of the four polyphenols were generally higher in powders obtained by vacuum freeze dryingthan in those prepared by hot-air drying, indicating that vacuum freeze drying is better for optimal preservation of polyphenols. None of three polyphenols assayed was found in some cultivars or after certain drying treatments. Based on physiochemical properties, our findings suggest that powders obtained after vacuum freeze drying are optimal for industrial use.
