This study is the conditions of location according to formed the times in the clan village. The results of this study are as follows ; 1. in the 15th century, the characterestics of the village established residencial place where mountain stream flowed surrounded by the mountain and deep in the mountains with superior quality land. That's because Sa-dae-bu put equal importance on beautiful scenery and practical benefit for living. Stream House provided economical foundation for Sa-dae-bu to be able to keep confucial manners by putting limit their economic status to small medium sized land owner. Topographical condition such as valley or hollow separated from the exterior maintained unification of consanguineous village in self sufficient farming society and held on to independent territory against external to be able to stay away from turbulent days so that they formed residential area of Sa-dae-bu clan. And the valley where flowed clean water was considered as the connection of continuous place where distinctiveness of form in each curve and and factor of calm and dynamic scenery of the clean stream. Scholars in the middle of Chosun Dynasty located in the utopia as place for confucious retirement to study, a place for refinement by combination with the nature or as a way of spacial practice based on Confucious view of nature. 2. in the 16th-l7th century, Most of existing consanguineous villages adopt deep in the mountains for refuge. at that place, upward rank was established by settlement of the ancestor who entered in the village first, the principal was placed in the center of the village and since descendants became numerous, it was serialized as the space of descendants. So, it was arranged in the order of social rank. Most of the villages showed development step by step started from precaution by apperance of the mountain to the lower part. It's because the topography of valley around the village worked as the natural hedge against external force and genealogy of the clan, regularity of social status, order of entrance into the village were reflected into residencial destribution. Also, order of the rank coincided with the one of aspects on geomancy. Genealogical rank within the village represented spacial rank. Houses of descendants and branch families were placed lower than the principal which showed worship to the principal. 3. In 18th century after, as the village was settled nearby cultivated land considering economical loss caused by long distance between residencial area and cultivated land, direction of sect followed by development of village expanded from the front part of the village to the rear part. The principal that was poped out to the front presented frontage over exterior. Therefore, residencial area of branch families expanded to the rear starting from the principal. This represented a slice of social structure at that time. after 18th century, spirit was percieved superior over material, After then, development of cultivation and expantion of land created difference of economic strength within one village. In order to maintain and show off the status of Yang-ban, economic power of indigenous land owner became fundamental, so, sense to worship and to keep the principal became weak eventually. Taking advantage of that situation, residencial area of branch family expanded to the rear part of the principal which showed dual disposition conflicted with each other. However, these clan rules were destroyed and new rules were created after 18th century because of the situation and consciousness at that time.

The mammary gland is made up of remarkably sensitive tissue, which has the capability of producing a large volume of secretion, milk, under normal or healthy conditions. When bacteria enter the gland and establish an infection (mastitis), inflammation is initiated accompanied by an influx of white cells from the blood stream, by altered secretory function, and changes in the volume and composition of secretion. Cell numbers in milk are closely associated with inflammation and udder health. These somatic cell counts (SCC) are accepted as the international standard measurement of milk quality in dairy and for mastitis diagnosis. NIR Spectra of unhomogenized composite milk samples from 14 cows (healthy and mastitic), 7days after parturition and during the next 30 days of lactation were measured. Different multivariate analysis techniques were used to diagnose the disease at very early stage and determine how the spectral properties of milk vary with its composition and animal health. PLS model for prediction of somatic cell count (SCC) based on NIR milk spectra was made. The best accuracy of determination for the 1100-2500nm range was found using smoothed absorbance data and 10 PLS factors. The standard error of prediction for independent validation set of samples was 0.382, correlation coefficient 0.854 and the variation coefficient 7.63%. It has been found that SCC determination by NIR milk spectra was indirect and based on the related changes in milk composition. From the spectral changes, we learned that when mastitis occurred, the most significant factors that simultaneously influenced milk spectra were alteration of milk proteins and changes in ionic concentration of milk. It was consistent with the results we obtained further when applied 2DCOS. Two-dimensional correlation analysis of NIR milk spectra was done to assess the changes in milk composition, which occur when somatic cell count (SCC) levels vary. The synchronous correlation map revealed that when SCC increases, protein levels increase while water and lactose levels decrease. Results from the analysis of the asynchronous plot indicated that changes in water and fat absorptions occur before other milk components. In addition, the technique was used to assess the changes in milk during a period when SCC levels do not vary appreciably. Results indicated that milk components are in equilibrium and no appreciable change in a given component was seen with respect to another. This was found in both healthy and mastitic animals. However, milk components were found to vary with SCC content regardless of the range considered. This important finding demonstrates that 2-D correlation analysis may be used to track even subtle changes in milk composition in individual cows. To find out the right threshold for SCC when used for mastitis diagnosis at cow level, classification of milk samples was performed using soft independent modeling of class analogy (SIMCA) and different spectral data pretreatment. Two levels of SCC - 200 000 cells/$m\ell$ and 300 000 cells/$m\ell$, respectively, were set up and compared as thresholds to discriminate between healthy and mastitic cows. The best detection accuracy was found with 200 000 cells/$m\ell$ as threshold for mastitis and smoothed absorbance data: - 98% of the milk samples in the calibration set and 87% of the samples in the independent test set were correctly classified. When the spectral information was studied it was found that the successful mastitis diagnosis was based on reviling the spectral changes related to the corresponding changes in milk composition. NIRS combined with different ways of spectral data ruining can provide faster and nondestructive alternative to current methods for mastitis diagnosis and a new inside into disease understanding at molecular level.

후기 산업사회에서도 자발적 문화인 버내큐러 디자인은 그 유용성을 가지고 기성품과 공존해 온다. 이러한 후기산업사회에서의 버내큐러 디자인산물에 대한 연구와 그 문화적 맥락을 이해하려는 시도가 부족한 상황에서 디자인생산자의 역할로서 의 사용자와 산물의 관계를 문화적 관점에서 연구할 필요성이 있다. 2장에서는 문헌고찰을 통해서 창조적 사용자 문화와 버내큐러 디자인 문화의 관계성을 연결하는 정의와 이해, 속성 ,주류디자인과의 차이성을 파악하였으며, 3장에서는 일상거리와 공사현장에서의 산물사례 실증을 통해 디자인산물의 일반적 특징과 과거와의 차이성을 살펴보았고, 4장에서 중심사례로서 60, 70년부터 현재까지의 유소년의 놀이문화가 사회경제적 배경, 문화를 통해 발생시키는 산물의 디자인 방식, 문화적 특징을 시대축에 따라 분석하였다. 결론적으로 첫째, 인간이 필요로 하는 모든 인공물은 레디메이드(read-made)된 형태로 존재하나, 사용자의 모든 행위와 대응하기에 적절치 않고, 보완적 형식인 버내큐러 디자인산물 현상이 나타나는 것이라 볼 수 있다. 둘째, 상위문화와 하위문화가 공존하며 발전하는 것과 같이 디자인에서의 주류적 디자인과 버내큐러 디자인은 그 공존적 연결성을 가지고 지속적으로 교차하며 나아간다고 할 수 있다. 셋째, 이러한 버내큐러 디자인에 나타나는 디자인적 특징으로서 환경생태학적인 롱라이프디자인 (long life design), 환경친화적 디자인(ecology design), 재활용 (recycling) 개념 등은 미래적 디자인방향에 유용한 특징이며, 즉 시대응적이며 신속하고 유연한 프로세스는 기존의 시스템적 어프로치, 계획성 마케팅의 통제적인 과정을 극복하는 대안적 프로세스의 가능성을 가지고 있다. 넷째, 유소년놀이문화의 버내큐러 디자인산물은 과거 순수형태에서 테크노 변형 놀이산물 문화로 변형되어왔는데, 이는 기성적 디자인이 갖지 못한 다양함을 보완하는 대안적 산물이며, 독립적 문화로서 지속성을 가져야 하는 디자인문화이다.

조선의 궁궐은 크게 법궁(法宮)과 이궁(離宮)으로 분류된다. 이와는 별개로 정궁(正宮)의 개념이 있다. 법궁은 정궁의 개념을 포함하고 있지만, 이궁이 정궁으로 활용되는 것은 정치적인 상황에 따른다. 한양 최초의 궁궐은 경복궁이며 법궁으로 지어졌다. 경복궁의 자연 지형은 왕권을 상징하는 백악산을 배경으로 하였으며 사신사가 뚜렷하다. 궁궐의 입지도 왕의 위엄과 권위를 나타내도록 궁궐 밖에서 잘 보이는 장소를 선정하였으며, 백악산의 능선을 따라 하나의 축선을 기준으로 일직선상에 삼문삼조를 배치하여 왕권의 정통성과 위계질서와 통일성을 추구하였다. 이궁(離宮)은 왕의 요구나 왕실의 수요 또는 정치적 상황에 따라 건축되었으며, 왕실의 일상생활 공간으로서 복수의 축선에 의해서 독립적이고 다양한 공간으로 조성되었다. 법궁은 양(陽)의 지형을, 이궁은 음(陰)의 지형을 선택하였으므로 전각을 배치하는 준거 또한 달라질 수밖에 없었다. 조선 궁궐의 조성에 있어서 가장 중요한 핵심은 왕기(王氣)였다. 궁궐 건설의 중요 요소는 풍수기맥과 금천이다. 풍수기맥은 왕기를 수용하는 통로였고, 금천은 왕기가 궁궐 밖으로 퍼져나가지 않게 하는 방법론이었다. 전형적인 풍수 지형을 선택한 법궁(法宮)인 경복궁의 경우 풍수 요소를 적재적소에 적용하고 있어서 풍수 원리를 충실하게 반영하였다. 반면에 이궁(離宮)은 비정형적이고 온전하지 않은 풍수 지형에 지어졌다. 풍수는 조선시대 지배계층의 자연관이며 지리관이었다. 이들의 지리관을 살펴봄으로써 전통문화 계승과 복원에 완성도를 높일 수 있을 것으로 생각한다.

영산강의 상류에는 4개의 농업용 댐들이 축조되어 있으며 각 댐의 물은 경작지 관개용수로 거의 모두 공급되고 영산강 본류로 방류되지 않고 있다. 또한, 관개용수의 대부분도 사용 후에 영산강으로 회귀하지 않고 격리된 상태의 별도 용수간선을 통하여 영산강 하류까지 흘러가기 때문에 영산강 본류의 유량 부족 문제를 가중시키고 있다. 이러한 원인으로 영산강 유량의 71%가 하수처리수로 채워지는 결과를 초래하였으며 이에 따라 수질뿐 아니라 수생태 건강성도 우리나라 4대강 중 가장 열악한 실정이다. 따라서 본 연구에서는 영산강 수질개선을 위한 여러 가지 시나리오들을 오염삭감과 유량증대를 함께 고려하여 개발하였고 QUAL-MEV를 이용하여 각 시나리오의 장래수질을 예측·분석하였으며, 이러한 연구결과로부터 얻어진 결론은 다음과 같다. 1. 영산강의 수질개선은 오염삭감을 통해 그동안 꾸준히 시행되어 왔으나 이제 한계에 다다르고 있어 앞으로는 오염삭감만이 아니라 유량증대(해수담수화 포함) 방법이 함께 중점 추진되어야 하며, 이러한 경우에는 영산강 수질목표의 달성도 가능하다. 2. BOD는 오염삭감 그리고 T-P는 유량증대의 방법을 통해 크게 개선될 수 있다고 예측되었으므로 수질목표의 달성을 위해 오염삭감과 더불어 유량증대가 함께 도입된다면 이들 상호 간에는 시너지 효과가 크게 작용할 수 있을 것이다. 3. 그러나 유량증대사업의 원활한 추진을 위해서는 투자비용을 늘리는 것도 중요하겠으나 기존의 용수 이해관계자들간에 형성되어 있는 갈등 문제를 협의·해소키 위한 꾸준한 노력이 선행되어야 할 것이다. 4. 댐의 건설, 용수배분 조정 등 강우 유관형 유량증대 방법은 기후변화로 인해 강우가 오랜 기간 발생하지 않으면서 대가뭄이 지속될 경우에 적용의 효용성이 떨어지거나 상실될 수 있으므로 앞으로 비슷한 조건이라면 강우 무관형인 해수담수화시설을 유량증대사업 중 우선 설치대상으로 고려해야 할 것이다. 그 이유는 이러한 시설이 우리나라에서 새로 건설하기 어려운 댐의 용수확보 기능을 대체할 수 있고 대가뭄이 장기간 지속될 경우에 물관련 재해방지도 가능하여 기후변화의 적응시설로서 유용할 수 있기 때문이다.

The Korean Medicine in the middle period of the Chosun Dynasty, with its clear independence, has made an excellent display of originality and superiority in the world medicine. By pinpointing its merits, classifying its lineal descent, and examining its relation with present Korean Medicine we can draw the following conclusions. First, the study on the history of Korean Medicine should, in terms of time, grasp the generational stream and, in terms of space, examine the relation with medicines of neighbouring countries, with both an inner and outer way of observing. Secondly, it is but a manifestation of the colonial view of history to classify the 460 years from Tae-jo(太祖) to Cheol-jong(哲宗) as Mordern Period of Korean Medicine. Therefore, the 250-year period between the mid-16th century of Myung-jong(明宗) to the late-18th century of later Jeong-jo(正祖), which saw a pivotal development of the national medicine as a practical medicine based on experiences, should be established as the period of Korean Medicine in the mid-Chosun dynasty. It is required from both nationalistic view of history and history as a positive science. Thirdly, Korean Medicine in the mid-Chosun period was developed with an emphasis on an independent development and creative succession of the national medicine, which was succeeded to the late-Chosun period. Fourthly, medical thought in the mid-Chosun period was much influenced by, and based on the practicality of, Shil-hak(or practical science : 實學) as was the current of the times. Fifthly, though medicine in the mid-Chosun period was generally developed, the recipes for the measles, epidemic and smallpox were especially developed owing to rage of epidemics, and the development of the acupunture as a military medicine was the most c lear because of the two major wars against the Japanese and Chinese, respectively in 1592 and 1636. Sixthly, Whang doh-yeon(黃道淵)'s Bangyak-happyeon(方藥合編), Lee je-mah(李濟馬)'s Tongui-susebawon(東醫壽世保元) and Lee kyu-jun(李奎晙)'s Uigam-jungma(醫鑑重磨) are representative medical books, in the late-Chosun period, which creatively succeeded national medicine. Seventhly, the lineage of national medicine flows from Hyangyak-jipseongbang(鄕樂集成方) Uibangryuchui(醫方類聚) Gugeupbang(救急方) to Uirimchualyo(醫林撮要) Tonguibogam(東醫寶鑑) Uimunbogam(醫門寶鑑) Jejung-sinpyeon(濟衆新編) and to Bangyak-happyeon(方藥合編) Tongui-susebawon(東醫壽世保元) Uigam-jungma(醫鑑重磨). These books are representative medical books in the early middle and late Chosun period respectively. On the basis of the above facts, it is clear that the orthodoxy of national medicine is in the direction of a creative succession and that is the best way to keep the spirit of Korean medicine today.

This paper analyzes the trend of fashion and make-up in 1990s and their relevancy to each other. Based on the chronological analysis, we propose a new category for the fashion and make-up trend in 1990s, which is 1) traditional ecology period(1990∼1994), 2) versatile trial or decadent period(1995∼1997), and 3) soft landing period based on the minimal neo-ecology and romanticism(1998∼2000). Between 1990 and 1994, there was no differentiation in seasons. It appeared that spring/summer and fall/winter trend have had no big differences. At the beginning in 1990s, it was basically based on ecology concept that emphasizes the natural image. However after 1995, seasonal differences in trend are appeared and there were various make-up designs. The trends of spring/summer in 1996 could be named as color revolution period that emphasized the unique and individual expression of each person. In 1997, black, pastel, and brown colors were the result of reinterpreting the classic and sexy images of 1960s to natural and modernistic image of 1997. Purple color started to be introduced to us. In 1998, pastel tone, pink, and purple color expresses the glamorous look based on the romantic feminism. S/S of 1999 is mainly represented by minimalism and avant garde. For fall/winter trends, brown color lines make-up comes to mix with romantic image and developed into wine, orange, neon colors in 1995 and 1996. These colors were the symbol of property and sentiment. Gold make-up emphasizing the eye area was the tendency of that period. In 1997, the fear of coming end of century was expressed as decadent image. At that time, ethnic and romantic image appeared with vivid color lines, gold, red and violet. In 1998, romanticism was popular again with modernism and ethnic mood. It expressed the romantic elegant image. The trend has returned to the ecology mood again in 1999. This ecology is somewhat different from the previous ecology. It adds a sofistaiced feeling and sportic fashion. To express natural and sportic image, they choose pink blush. In coming 2000 as a new millennium, the yellow color will be main the stream to express vision, dream, and happiness in both fashion and make-up as an accent color. The minimal design and minimal tools will be used for the design and make-up, respectively. In addition, the fusion concept will dominate the fashion and make-up industry in the globalized and boundariless age. Through this paper, we hope that make-up can be accepted as a part of total fashion in its relationship with other elements such as shoes, clothes and accessory and that it can be considered as a independent art that has direct influence on people and industry.

According to Confucianism, the world before Confucius focused on respecting the heaven which meant that everything could be done by the heaven. After the period of Confucianism, Joo-Ja asserted that everything could be done by nature. During the Chosun Dynasty, philosophers such as Seo Kyung-duck, Lee Hwang, and Lee Yi talked about four characters and seven passions of human being. They started to focus more on the inside of human nature. During the later period of the Chosun Dynasty, a philosopher by the name of Dongmugong Lee Jema analyzed that one's nature and feelings can change his or her external matter and the function of internal organs by purity or impurity of one's mind. Based on these analysis, Dongmugong discovered 'sasangin' which puts more emphasis on one's state of mind compared to the outside the world. Also, Dongmugong tried to figure out the connections between Confucianism and medical science. If you use change fire and stone theory which is difference between hado and nock-seo to expain four seven theory one's mind could be define as four natural characters and seven feelings. From four seven theory four is ying and seven is yang. This is the method of cure and understand the structure of human body. And also, four natural characters and seven feelings can be divided into heaven and earth. You can see Four natural characters is far more similar to heaven and seven feelings are similar to earth. According to four-seven theory hado is permanent and you can find out 'sasangin' is permanent also. Since seven feelings are influenced by sam-jae, you can analogize there are 21 different types in 'sasangin'. An underlying principle should there be 28 different types of sasangin instead of 21 different types of sasangin but one quater of sasangin is hidden according to samhyuniljang theory. All creations in the world are organized by unification of the great absolute and symmetry distinction of yingyang. With these facts identity of the heaven, earth and man which is named samjae generates symbols of independent sasang. And also, sasang generates relations between five element, six energy and the six family relation. From six family relation comes seven feelings of man which creates a category of the eight trigrams for divination and unification of nine palace. All these process are united.

히스토그램은 최근들어 많은 관심을 끌고 있다. 히스토그램은 주로 상용 데이타베이스 관리 시스템에서 질의 최적화를 위해 속성의 값에 대한 데이타 분포를 추정하는데 사용되었다. 최근에는 근사 질의와 스트림 데이타에 대한 연구 분야에서 히스토그램에 대한 관심이 커지고 있다. 관계형 데이타베이스에서 두 개 이상의 속성에 대한 결합 데이타 분포를 근사시키는 가장 간단한 방법은 각 속성의 데이타 분포가 결합 데이타 분포에 독립적이라고 가정하는 속성 값 독립(Attribute Value Independence: AVI) 가정하 에서 각각의 속성에 대해서 히스토그램을 만드는 것이다 그러나 실제 데이타에서 이 가정은 잘 맞지 않는다. 따라서 이 문제를 해결하기 위해서 웨이블릿, 랜덤 샘플링, 다차원 히스토그램과 같은 기법들이 제안되 었다. 그 중에서 GENHIST는 실수형 속성에 대한 데이타 분포를 근사시키기 위해 고안된 다차원의 히스토그램이다. GENHIST는 데이타 분포를 좀 더 효과적으로 근사시키기 위해서 중첩되는 버킷을 사용한다. 본 논문에서는 SSE(Sum Squared Error)를 최소화시키는 중첩되는 버킷들의 최적 빈도를 결정하는 OPT 알고리즘을 제안한다. 처음에 GENHIST에 의해 중첩되는 버킷으로 구성되는 히스토그램을 만든 후에 OPT 알고리즘에 의해서 각 버킷의 빈도를 다시 계산해서 GENHIST를 개선시킬 수 있다. 실험 결과는 OPT 알고리즘이 GENHIST에 의해 만들어진 히스토그램의 정확도를 크게 개선시킴을 보여준다.
