The series of ‘Dubonnet’poster is one of the masterpieces of Cassandre who was the leader of advertising poster in 1920's and 1930's. Orihinally it was a triptych, but it was developed as a serial work later through lettering and seasonal advertising posters. It was kept in circulation for more than two decades and issued in a variety of formats. In this thesis I tried to figure out the artistic character and uniqueness of Cassandre's poster by analyzing it with many different points of view of the poster, the stream of changing style and influence from the Avant-garde painting. In chapterII, objectively analyzing the series of‘Dubonnet’one by one, I examined the method that Cassandre used to deliver the concept of advertising and his message. The triptych, the first one of series of Dubonnet poster is witty, the slogan is a pun using the words dubo(doubt), bon(good), and Dubonnet, and the theme is treated as an animated sequence in the manner of a comic strip. In the following winter and summer seasonal advertising posters, the‘Dubonnet man’in the same position is enjoying the‘Dubonnet’, irrespective of the hazards of climate and season, There was a change towards 1929 that rectilinear design gave place to supple and undulating lines in Cassandre's posters. Seasonal advertising posters also showed the change, and the tendency of realistic and concrete elements of an expression was strengthened. In chapterIII, I studied three as main characters of Cassandre's poster. The first one is simple and geometric expression, second one is uniqueness of figures and the last one is important roll of lettering. Cassandre believed that there were fundamental differences between the function of a poster and that of a painting. He also recognized that the symbol was the essential element in the poster design, which would be simply and swiftly recognized. The recognition led him to simple design and bold geometric abstraction. He was a man who knew the value of copy in advertising and developed it fully in his simplified geometric compositions by integrating of letterforms and image. The‘Dubonnet man’is geometrized, almost featureless. This approach of rendering human beings was one that Cassandre had used from the early years, most notably in his posters for Dubonnet.

UHI (Urban Heat Island) is an important environmental issue occurring in highly developed (or urbanized) area such as Seoul Metropolitan City of Korea due to modification of the land surface by man-made structures. With the advance of the remote sensing technique, land cover types and LST (Land Surface Temperature) influencing UHI were frequently investigated describing that they have a positive relationship. However, the concept of land cover considers material characteristics of the urban cover in a comprehensive way and does not provide information on how human activities influence on LST in detail. Instead, land use reflects ways of land use management and human life patterns and behaviors, and explains the relationship with human activities in more details. Using this concept, LST was segmented according to land use types from the Landsat imagery to identify the human-induced heat from the surface and interannual and seasonal variation of LST with GIS. The result showed that the LST intensity of Seoul was greatest in the industrial area and followed by the commercial and residential areas. In terms of size, the residential area could be defined as the major contributor among six urban land use types (i.e., residential, industrial, commercial, transportation, etc.) affecting UHI during daytime in Seoul. For temperature, the industrial area was highest and could be defined as a major contributor. It was found that land use type was more appropriate to understand the human-induced effect on LST rather than land cover. Also, there was no significant change in the interannual pattern of LST in Seoul but the seasonal difference provided a trigger that the human life pattern could be identified from the satellite-derived LST.

Gwae(卦氣) theory was one of the main theoretical foundation of yiology in the Han(漢)-dynasty. It was based on the concept that the trigram or hexagram of the book of change corresponds to the seasonal point such as 24 solar terms in one year, so there was so much influence from astronomy and divination system of that time in the development of theoretical principle of Gwae(卦氣) theory. Since Han(漢) Dynasty, the theoretical method such as Gwae(卦氣) theory that correlates the astronomy and divination system with the book of change, had become one of the main academic thoughts throughout the entire history in China, and it was also like that in medicine. Nevertheless there still exists the skeptical sights that Gwae(卦氣) theory was not a part of orthodox yiology, that had been developed by Confucian scholar and had also been recognized as the right path to the study of the book of change. Nowadays because of the new opportunity such as the excavation of the ancient silk script, this kind of controversy has moved on its another step. With regard to this problem, this article will treat the current thoughts about the Gwae(卦氣) theory and think about the substantial basis of each point of view.

Wells (1967)에 의해 제안된 2nd order 파랑들의 비선형 상호작용에 의한 바닥 부근에서의 유속분포에 대한 왜도(skewness)를 다시 계산하고 재평가하였다. 해안선에 수직한 방향의 퇴적물 이동 방향을 그 유속의 3차 모멘트(왜도)의 부호에 따라 알 수 있음을 보였고, 해빈이 어떤 교란을 받은 후에도 원래의 평형을 회복할 수 있는 새로운 개념의 중립수심을 제안하였다. 또한 계절적인 파랑조건의 변화에 따른 해빈단면의 변화(폭풍-너울 단면)도 종래의 단순한 파랑구배에 의한 구분보다는 파랑의 비선형 상호작용으로 설명되었다. 즉, 파랑의 비선형 작용이 강할 때에는 (폭풍파) 해빈은 침식을 받으며, 반면에 비선형작용이 약할 때에는 (너울파) 해빈은 퇴적됨을 보였다.

Light environment and growth of Panax ginseng In habitat and cultivation under natural shade were renewed. Grower's experiences on ginseng stand In relation to light environment were assessed. Change of shading method and grower's concepts on light requirement of ginseng plant in Korea, Manchuria and Japan was counted. Growth of wild ginseng was better under rich light. Optimum crown density index appeared to be 0.7 In natural habitat and 0.4 to 0.7 for the cultivation in forest. Change of light Intensity in forest was greatest in May and reached near to constant value (from 40% to 3% for broad leaf deciduous forest and loom 4% to 2% for pine forest). Insufficient light condition induced long and thin stem, poor flowering and seed bearing, and sequent dormancy. Relation between light and ginseng strand was not clear but light Interception with cool weather was effective. Topography and orientation of bed have been deeply considered for light environment. Panel or bark of won were used for shading in deep forest manly In Manchuria while reed blind and straw thatch were used in Korea. Kinds and number of shades material and seasonal or daily schedule have been simplified probably by labor pressure due to eulargement of plantation. Post height has been greater while width of roof, bed and ditch has changed lisle. Scientific survey in the past omitted important light control methods (complete light hardening etc) which has been practiced in specific areas. The concept and technique of light control in the past in Korea were delicate and intensive including the control of temperature and moisture. For the application of old concept in modem cultivation precise Investigation of the technique including the measurement of light, temperature and moisture is needed.

X11ARIMA는 1965년 미국 센서스국에서 개발된 X11분석 방법에 기초한 시계열 분석방법으로 Dagum(1975)에 의해 개발되었다. 이 기법은 Dagum(1988)에 의하여 북미지역의 174개의 경제지수를 바탕으로 일부 기본모형이 수정·보완되어 오늘날에 이르고 있다. 최근에는 회귀 모형과 ARIMA모형을 동시에 고려하여 특이치와 추세 변환효과(outlier arid Trend-change effects), 계절변동(seasonal effect), 그리고 달력효과(calendal effect) 등을 추정한 William 등(1995)과 Chen과 Findley(1995)의 X12ARIMA분석 방법이 소개되었다. 그러나 위의 모든 기법들은 주로 북미지역의 경제지수를 기초로 하고 있다. 본 논문에서는 우리나라의 산업중분류에서 산출되는 102개(생산(27), 출하(27), 재고(27), 가동률(21))의 지수에 대한 우리나라의 표준 ARIMA모형을 제시하고, 우리나라에 적합한 이동평균항수를 제공하고자 한다. 그리고 우리나라의 설, 추석 등의 명절효과를 태양력으로 전환함과 동시에, 최근에 논의되고 있는 X12ARIMA에서 사용되는 회귀모형과 ARIMA모형을 동시에 고려하는 명절효과를 도출하고자 한다.
