강우자료는 수문 모델링 작업에서 가장 기초적인 수문학적 입력자료로 시간과 공간에 따른 변동성이 크므로 규명하기 복잡한 수문현상 중의 하나이다. 산악지역이 많은 우리나라의 지형학적 특성과 태풍, 장마 및 특히, 최근의 게릴라성 집중호우 등으로 인하여 이러한 변동성이 더욱 커지고 있는 실정이다. 장기간 실측된 수문기상 기초 자료가 부족한 우리나라의 실정상 홍수예보 및 수공구조물 설계를 위해 정확한 강우량 자료의 취득이 선행돼야 한다. 따라서 적절한 장소에 수문관측소 설치 및 관리를 통해 양호한 강우량 자료를 획득해야 하지만, 현장 여건상 등의 이유로 미계측 및 결측, 이상자료가 발생하고 있다. 따라서 이러한 미계측 혹은 결측지점의 우량을 추정할 수 있는 방법을 비교, 분석하여 적절한 보정과정을 수행할 필요가 있다. 그간의 연구에서는 미계측 지점 혹은 산악지역에서의 점 강우량 보정방법에 대한 연구가 진행되었지만, 본 연구에서는 '도시홍수재해관리기술연구사업단'에서 운영 중인 도시하천 유역 특히 소배수구역에서의 결측 자료에 대해 여러 추정 방법을 비교, 분석하여 적절한 방안을 찾고자 한다. 이를 위하여 중랑천 유역의 3개 소배수 구역(월계1 배수구역, 군자 배수구역, 어린이대공원 배수구역)에 설치된 3개 우량관측소와 건설교통부 관할 우량관측소 2개소의 우량자료를 사용하였다. 본 연구에서는 결측치 보간을 위하여 널리 이용되고 있는 산술평균법(Arithmetic Average method), 역거리법(Reciprocal Distance Squared method), 거리고도비율법(Ratio of Distance and Elevation method), 인근관측소와의 관계식 이용, 크리깅방법(Simple Kriging method)을 비교, 검토 적용하였다. 중랑천 유역의 소배수구역을 대상으로 연중 발생하는 큰 호우사상에 대해 임의의 강우관측소를 결측지점으로 가정하고 주변의 강우관측소로부터 각각의 방법을 이용해 가중치들을 산정하여 결측지점의 강우량 값을 보정하고자 하였다. 또한 각각의 방법을 이용하여 얻어진 결과에 대해 실측값과 보정값의 오차정도를 평균절대오차법(Mean Absolute Error)과 제곱평균제곱근오차법(Root Mean Squared Error)에 의해 산정하여 보정 방법간의 효율성을 검토하고자 하였다.

The use of radar rainfall for hydrological appraisal has been a challenge due to the limitations in raw data generation followed by the complex analysis needed to come up with precise data interpretation. In this study, RAIDOM (RAdar Image DigitalizatiOn Method) has been developed to convert synthetic radar CAPPI(Constant Altitude Plan Position Indicator) image data from Korea Meteorological Administration into digital format in order to come up with a more practical and useful radar image data. RAIDOM was used to examine a severe local rainstorm that occurred in July 2006 as well as two other separate events that caused heavy floods on both upper and mid parts of the HanRiver basin. A distributed model was developed based on the available radar rainfall data. The Flood Hydrograph simulation has been found consistent with actual values. The results show the potentials of RAIDOM and the distributed model as tools for flood prediction. Furthermore, these findings are expected to extend the usefulness of radar rainfall data in hydrological appraisal.

최근 기상이변에 따른 국지성 호우 등으로 인하여 지역별로 홍수량 차이가 많이 나고 있는 상황으로 유역내 중요시설물 및 인명의 보호를 위해서는 유역의 특성을 정확하게 반영한 홍수분석이 필수적인 실정이다. 유역 주요지점의 정확한 홍수량을 산정하기 위해서는 지역특성이 반영된 호우를 선정하고, 유출모의를 위한 유역특성이 잘 구현되어야 한다. 이를 위해서는 홍수량산정에 영향을 주는 매개변수의 정확한 산정이 필요하며 본 연구에서는 미공병단(US Army Corps)에서 개발하여 배포한 차세대 프로그램인 HEC-HMS(v3.3)를 이용하여 집중시간, 저류상수, Curved Number, 감수상수, 초기손실, 초기기저유량, Threshold 등 7가지 매개변수에 대한 최적화를 수행하였다. 종래에는 첨두홍수량을 중시하여 집중시간과 저류상수는 최적화하고 나머지 변수들은 실측치 및 계산값을 적용하였으나, 금번 연구에서는 첨두홍수량 및 총유출량 모두 관측값에 최대한 일치하도록 7가지 매개변수를 최적화하는 방안 및 최적화시 초기값 선정이 매개변수 최적화에 미치는 영향을 연구하였다. 매개변수 최적화 순서는 먼저 전체적인 평균유출량 또는 평균유출고가 실측치와 모의치 간에 일치하도록 CN, RC를 보정하고 다음 단계로 첨두발생시간이 일치하도록 Tc, K를 보정하고, 마지막으로 홍수 수문곡선의 형태를 결정하는 나머지 매개변수를 조정하여 전체적인 수문곡선의 형태와 첨두홍수량이 일치하도록 수행하였으며, Tc, K, CN 등의 중요 매개변수는 신뢰구간(계산치의 0.8${\sim}$1.2)을 설정하여 목적함수의 수렴을 유도하였다. 위를 이용하여 수렴된 매개변수들로 강우-유출 모의를 분석한 결과를 기존 홍수사상과 비교한 결과 상당히 근접한 결과를 도출할 수 있어, 매개변수는 7가지 모두에 대한 최적화를 가능한 것으로 연구되었으나 목적함수들의 수렴되는 과정에 대해서는 좀 더 심도있는 고찰이 필요할 것으로 판단된다.

This thesis discusses the emerging system of value and structure of feeling in today's Chinese society through analyzing Chinese main theme TV series. The 2000s' Chinese main theme TV series represents Chinese's anger and nervousness into the structure of narrative, and they try to form a bond of sympathy with the audience by various characters which represent the common people. Main characters are no longer revolutionists who internalize ideas of socialism and collectivism, but they put emphasis on individuals' thoughts, tastes, and values, and freely express them. Individualism, which was negatively represented and excluded in main theme TV series before 2000s, are compromised and included in today's Chinese dramas. Even though dramas represent the superiority of communism, individuals' choice of various value and faith is positively and flexibly considered. There is a new phenomenon where female figures are no longer passive and dependent, but they are portrayed with given with unique roles and status. Although main theme TV series are directed under the state and government's supervision, they exist in the relation where market, state, drama text, and audience interact.

This paper examined the immanent ideological bases in the transformation motif of animations, focusing on several leading animation works in which a human gets transformed into an animal, or vice versa, and also took a look at what meaning and function this transformation motif adds to their narrative. As a result of analyzing the animation texts centered on the transformation motif, transforming into an animal in is applied as a means for punishment. It shows the notion that the animals need men's care, that is, the anthropocentric point of view that the animals need to be overcome and conquered had a strong influence upon this work. However, in , a boy realizes that the animals(nature) are not the targets to conquer and learns to appreciate the principle of Mother Nature through the process of becoming a bear. By this description, this work shows deep reflection on nature and human being. Lastly, shows a desire to overpass the border to forbidden things, and describes the relationship between men and animals(nature) in a variety of perspectives. Furthermore, this study examined how the variety of attitudes toward the transformation targets is formed in each work.

In the present, animations of auteurism and aestheticism became a unique genre of art that expresses directors' idea. 'Tale of Tales' by Yuri Norstein, a Russian animator, is a paper animation that emphasizes the cut out technique and picturesque feeling as well as complicated structure of sequence in expressing metaphysical themes in the author's historical realism. It is evaluated as unique and creative. The present study analyzed the montage technique applied through the development of several symbolic images, the diachronic expression of contradictory worlds, the unique foreshadow of revealing the causes of results later, rapid repetition of urgent and serious situations, the movement of the camera to express the psychological distance between two characters in different situations and the process of editing. The derived results of this study are expected to be helpful in the works of animators of auteurism and aestheticism.

The spiritual world of the ancient times has precious values which forms the origin of human thought. This study aims to reevaluate ancient people's particular views on man in their spiritual world reflected through gods' ornaments by studying the human race's fundamental spiritual world gradually disappearing due to science development from Egyptian gods' ornaments expressed symbolically in Ancient mythical components. Although evidently ornaments in Egypt served for decoration, the basic purpose was exorcism as amulets, a shamanistic purpose to be protected from mystical and hostile powers by carrying them on the vulnerable spots of the body. As this aspect indicates, the human race tried to solve their self-insoluble transcendental issues through the help of supernatural power, pursuing to lead their lives there within. As a result, Egyptian ornaments; First, the deity raised their value by deifying human-beings. Second, the nobility enhanced their dignity by having goddesses wear the same skirts as theirs. Thirds, all deities maintained their class society by wearing fpassiums, bracelets, and anklets. Fourth, the resurrection was symbolized through gods and goddesses in charge of the afterlife.

A Web database System is a large-scaled multimedia application system that has multimedia processing facilities and cooperates with relational/Object-Oriented DBMS. Conventional hypertext modeling methods and DB gateway have limitations for Web database because of their restricted versatile presentation abilities and inefficient concurrency control caused by bottleneck in cooperation processing. Thus, we suggest a Dynamic Navigation Model & Virtual Graph Structure. The Dynamic Navigation Model supports implicit query processing and dynamic creation of navigation spaces, and introduce node-link creation rule considering navigation styles. We propose a mapping methodology between the suggested hypertext model and the relational data model, and suggest a dynamic allocation scheduling technique for query processing server based on weighted value. We show that the proposed technique enhances the retrieval performance of Web database systems in processing complex queries concurrently.

Developing cultural contents in cultural creativity industry is very practical process recently. Research about Jeju's legend and myth should be the basic theory for cultural contents development based on local cultures. Jeju Naewotdang Musindo 10 gods paintings are unique colored pictures, appointed as Jeju folklore material No.7 and national important folklore material No. 240. Jeju-Do is remained the springhead of absorbed into unique culture for a long time because of Jeju's geographical environment condition. Jeju Musindo could be related with the symbol of Jeju's myth images and the springhead of emotions of our typical country people. It would be analysed by Wucius Wong's design style theory for approaching visual image and symbolic meaning. This research about Jeju Naewotdang Musindo 10 gods paintings could provide design analysis methodology for further theoretical studies about Jeju's legend and myth for Jeju's unique cultural contents.
