삼국사기, 증보문헌비고 등에 기록된 신라의 천문관측기록 142건을 분석하였다. 두드러진 특징으로는, 첨성대가 만들어지기 전에는 100년당 평균 7건의 기록을 남긴 반면 첨성대가 만들어진 후부터 신라가 멸망할 때까지는 100년당 평균 33건의 천문관측기록을 남겼다는 것이다. 또한 첨성대가 만들어지기 전의 기록들은 주로 일식과 혜성 등 체계적인 관측을 하지 않아도 알 수 있는 현상들이 대부분인데 반해 첨성대가 만들어진 이후부터 유성이나 행성 현상 등 전문적인 천문학자들에 의한 체계적인 관측이 필요한 현상의 기록이 더 많다는 특징도 있다. 특히 유성 기록의 경우 첨성대가 만들어진 이후부터는 나타나고 사라진 천구상의 위치를 구체적으로 기록하고 있다는 특징도 보인다. 이는 특정한 곳에서 매일 밤 체계적으로 천문관측이 이루어졌음을 의미한다. 게다가 647년, 673년, 710년, 768년에 관측된 유성은 떨어진 위치를 정확히 기록하고 있는데, 각각 월성, 황룡사와 월성 사이, 삼랑사 북쪽, 황룡사 남쪽이다. 이 위치들이 대략 타원 상에 있는 것으로 봐서 그 타원 영역 안에서 관측이 이루어졌을 것으로 추정된다. 그리고 그 타원 영역 안에 첨성대가 있다는 것은 첨성대에서 관측이 이루어졌을 가능성이 매우 높음을 시사한다. 특히 673년의 기록은 다른 유성 기록에 비해 떨어진 위치가 더 구체적인데, 이는 유성이 떨어진 위치와 비교적 가까운 곳에서 관측이 이루어졌을 것이라 짐작할 수 있다. 실제 첨성대의 위치가 그곳에 가깝다는 점에서 첨성대에서 이들 유성을 관측했을 거라는 강한 가능성을 제시하고 있다.

We study on the astronomical calendars that was used in the Silla era. The calendars are deduced from the records in Samguksagi. They were influenced from calendaric system of Tang Dynasty, which are Lin duk calendar(麟德曆), Ta yen calendar(大衍曆) and Sun myung calendar(宣明曆). We analyse them in detail according to the time and duration of use. Water clock system of Unified Silla was used four water vessels for supplying water. We found the model from documents on ancient water clock that are appeared in the old Korean, Chinese and Japanese historical records. We have assumed the model of Unified Silla clepsydra is similar type with Chinese records during Tang dynasty and with Japanese reconstructed water clock in Temple Asoka. After fluid dynamic experiment, we decide the suitable diameter of supplying pipe and volume of the vessels used in the clepsydra. We introduce the experimental instruments and methods for accomplishing the clock. We designed and reconstructed the water clock of Unified Silla and float rods for measuring time, that is based on the Silla's calendaric system.

All human being can't exist by oneself. That is, all human being depend on intimate attachment for their survival. Physical and psychological powers and control functions are prerequisites for one's survival and these serve important functions in interpersonal relationships. There are two kinds of powers and controls. One is positive power which helps one survive effectively. Another one is negative power which disturbs one's effective survival. Introspection is one of the positive power and most important process in understanding oneself and others. Thus, the purpose of this study is to elucidate the physical and psychological meaning of the characteristics of water and based on this meaning, to suggest one way of introspection. The authors reviewed the precept of water which is described in Bible and oriental classical books such as 'the Analects of Confuicus(論語)', 'Tao Te Ching(道德經)', 'Mencius(맹자)', 'Chronicle(史記)', 'The Doctrine of the Mean(中庸)', 'University(大學)'. The author also reviewed 'The History of Three Countries(삼국사기, 삼국유사)', 'The Precept of Religion', and 'the modern poems' which includes the symbolic meaning of water. The results are summarized as follows：1) The flow of water itself is the expression of introspection. Because, water does not flow without filling a puddle. 2) Water is the symbol of 'Immortality'. 3) Water symbolizes 'Modesty and Trust'. 4) Water is the symbol of 'Freedom from Greed'. 5) Water symbolizes 'Goodness and Beauty'. 6) Water symbolizes 'Naturality and Love'. Immortality, Modesty and Trust, Freedom from Greed, Goodness and Beauty, and Naturality and Love are eternal, universal values which all human should seek and achieve. By the process of introspection through the symbolic meaning of water, we can achieve these positive aspects of human mind and spirit.

Since the outbreak of the brown planthopper (Nilaparvata lugens) in 1915 caused tremendous losses in rice production, one of the more effective method of prevention of such a disaster could be the establishment of longterm forecasting system, In 1916 the author indicated there was a correlation between sunspot activities and brown planthopper and the white back planthopper outbreaks. However, the examples seem to be too small size to state a definite correlation. The purpose of the present study IS to revi~w the history of the brown planthopper outbreaks, and to establish a more effective forcasting system. The present forcasting methods are based on light trap catches of adults which already migrate into this country from mainland China. The regular cycle of 11.2 years of sunspot activity began in 1710, and was continued to present. To gather more records of brown planthopper, the author checked 'Joseon Wangjo Silrok' and analized the so-called 'Hwang' 'Hwang-chung' and 'Chung' which have multiple meanings, together with 'Samguk Sagi' 'Goryo Sa' and 'Munheon Bigo.' The results obtained by the about from review of these old literature citations revealed that ten species of insect and unknown species were involved: i. e., pine moth (Dendrolimus spectabilis), army worm (Mythimna separata), brown planthopper (Nilarvata lugens), white-back planthopper (Sogatella furcifera), migratory locust (Locutsa migratoria), rice stem borer (Chilo suppressalis,), mole cricket (Gryllotalpa africana), rice-plant weevil (Echinocnemus squameus), cut worm (Euxoa segetum), and mulberry pyralid Margaronia pyloalis) The suspected incidence of planthopper in old records expressed by 'Hwang' or 'Chung' revealed a total or 25 out of 37 in 'Samguk sagi,' 21 out of 49 in 'Goryo sa,' 9 of 73 in 'Wanjo-silrog,' and none of 8 in 'Munheon bigo' were planthoppers. Therefore, a total of 36 out of 167 records of insect incidence in the old literature can be possibly attributed to planthoppers. The brown planthopper and white-back planthopper migrate together to Korea every year from mainland China, However, the number of each species are differ by year. In 1975 outbreak the brown planthopper was dominant; and the white-back planthopper prevailed in 1946 and 1977 outbreaks, During the course of this study, the author was able to add a new record of outbreak of planthop per. In 1916 the white-back planthopper outbreak caused serious losses in Chungcheong-namdo and Jeonla-namdo, with losses estimated as high as 160 and 190 thousand seok (23.2 and 27.5 thousand M/T), in Naju and Secheon county, respectively. Since 1912, major outbreaks of brown planthopper or white-back planthopper have been recored 5 times. These occurrences coincide and well matched the period of minimum number of sunspots, With these authenticated records of planthoppers, the author believes there is a close correlation between brown planthopper and white-back planthopper outbreaks in Korea and sunspot activities. Therefore, in years of low number of sunspots, we should watch for and expect outbreaks of these. insects. At this time, it will be necessary to provide all possible prevention measures.

Until now, the Korean archeological community has only been able to introduce the findings of classical archaeology developed in the West, and it also suffers from a lack of concepts and academic achievements. The domestic archeological community also started to develop later than that of the West, when it began to analyze ancient history and relics through the classic works of history titled Samguk sagi (三國史記) and Samguk yusa (三國遺事). Furthermore, it is actively utilizing the Chinese classics, such as the Samgukji (三國志) and Huhanseo (後漢書), as well as certain Japanese classics such as Ilbonsegi (日本書紀). Due to the total lack of domestic classics, however, there are few details about the formation of ancient polities, national changes, and inter-country negotiations and exchanges, as well as numerous other unresolved issues. This study raises the need to revamp classical archaeology in order to solve these problems. The concept of classical means 'all records made in the past' in the shallow sense, while the meaning of the historiography means "historical records according to the taxonomy of the old book." Classical archaeology is a field in which the classics are analyzed and interpreted so as to study the culture of the past. This section has set up a wide range of classical categories, and has found that the classics can be used in a meaningful way in classical archaeology through the use of the Gongjagae (孔子家語). The use of the classics in classical archaeology could produce significant results if the relevant DB is managed by various institutions and organizations using proper techniques of analysis including big data analysis.

The purpose of this study was to identify and to classify the names of costume colors of women of Silla. The results of this study can be summarized as follows; Until now scholars and researchers interpreted nine colors in Sam Guk Sa Ki as nine colors explained in the dictionaries. However, term, nine colors in the contexts did not refer to the literary meaning of nine colors such as blue, red, yellow, white, black, green, purple, pink, and navy blue as explained in the dictionaries. 'Nine colors' of Silla were women's costume colors which were specified in the royal edict in the texts. Thus, 'nine colors' of Silla had a specific meaning rather than literary meaning. 'Nine colors' of Silla women's costume were identified as red( ), yellow(黃), purple(紫), purplish pink(紫粉), gold powder(金屑), pink(紅), yellow powder(黃屑), dark pink(緋) and dark purple(滅紫). These 'nine colors' were actually prohibited colors in women's costume in the royal edict. Women from true bone, the highest class, were prohibited the use of tow colors of red and yellow out of nine colors. While women from four du pum and common class were forbidden the use of nine colors out of total of nine colors. Kinds and numbers of colors of costume were used as a means of differentiating the social class and rank of women in Silla. Also it was found that women of Silla favored red purple, pink tones and yellow color in their costume and these colors were fashionable colors among women of Silla. These fashionable costume colors of Silla women seems to be influenced by fashions of women of T'ang dynasty of China. Red, purple, pink, yellow and green were favorite colors of women of T'ang dynasty of China.

The purpose of this study is to examine misnomers about King Heungdeok's "Prohibition of Clothing" by comparing the writings of Jeongdukbon [正德本] and Juzabon [鑄字本], which were different versions of the original texts of "Samguksagi [三國史記]", with 11 related books written between 1948 and 2012. In addition, this study is reconsidered the terms about several clothes as well as the values of fabrics. The study has come up with the following conclusions. 1. We suggested the correction about a misnomer in the 11 books and the misnomers for fabric items appeared most frequently. The records of Jeongdukbon about some of the items were different from ones of Juzabon, especially regarding noble woman's sash were written according to the record of Juzabon in most of the related books. However, when the commonplace woman's sash was taken into consideration, we could suppose that the record of Jeongdukbon was more reliable. 2. We examined the terms for Yodae [腰帶] and Yoban. It can be inferred from the original texts that the Yodae were different in material and function compared to the Dae [帶]. In other words, the wearing position of male's metal Yodae was the waist, whereas the females wore their Dae made of fabrics on their chest. An example of this can be seen from the female clay images of Tomb Yonggang-dong [龍江洞]. Moreover, female's Yo and Ban were distinct items on the basis of documents. For this reason, we suggested that Yodae and Yoban should be separated and written in books. 3. We suggested that Ju [紬, silk tabby] might be valuable according to an result of analysis about the value of recorded fabrics. Besides, Po [布, hempcloth] presumably were used as higher quality fabric than Myeonju [綿紬, silk tabby] on some items because Po was graded on the density by each class.

과거에 발생한 극한홍수에 대해 역사기록 혹은 고고학적 발견을 통해 경향성을 연구하는 것은 세계적으로 많은 관심을 가지고 수행되고 있다. 특히, 기후변화와 관련하여 시추 자료 분석에 의한 연구는 과거에도 극한홍수가 발생하였음을 보여주고 있으며, 일기와 같은 개인적인 기록물에도 이런 재해에 관한 기록이 남아 있다. 우리나라의 역사기록은 측우기의 앞선 발명과 맞물려 세계적으로 찾아보기 어려운 매우 상세한 내용을 담고 있다. 삼국사기를 비롯하여 고려사에는 그 시대에 발생하였던 주요 홍수에 대해서는 정성적인 기술이 되어 있으며, 특히 조선왕조실록에는 조선왕조가 개국된 이래로 500년간 발생한 홍수와 피해지역 및 피해규모를 자세히 기록하고 있다. 본 연구의 선행연구에서는 과거 청계천에서 관측된 측우기 기록을 이용하여 홍수수문분석을 수행한 후 과거 청계천의 극한홍수량을 산정하였다. 본 연구에서는 이러한 홍수량 산정결과를 토대로 HEC-RAS를 이용하여 과거 청계천에 대하여 각 홍수사상별 홍수위를 산정하였다. 이렇게 산정된 홍수위를 과거 역사기록상의 피해기록과 비교 분석하기 위하여 수치고도모형(DEM)의 이용으로 공간적 피해규모를 평가하고자 하였다. 모형의 입력 자료로는 하도구간 및 하천단면, 조도계수, 하상경사, 상 하류단 경계조건 등이 필요하다. 이를 위해서 과거 청계천에 대한 하천 단면자료 및 조도계수 등이 필요하나 대상지점의 과거 실측자료가 없는 바 청계천 개수계획평면종단도(1936년, 경성부), 준천사실(1760년), 동국여지비고(1870년), 조선지형도집성(1921년), 경성지적도(1912년), 청계천 유물 발굴조사보고서(2006년) 등의 고문헌을 통하여 청계천 본류 구간에 대하여 단면 입력자료를 구성하였다. 또한 실제 청계천의 주변부 피해양상을 확인하기 위하여 청계천의 지류구간에 대해서도 금천교 발굴조사보고서(2003년), 영천교 발굴조사보고서(2003년) 등의 자료와 함께 근대까지의 기록물들을 활용하여 단면 입력자료를 추정하였다.
