This study was conducted to examine the chronology of Taesil Seokham(Taesil Stone Boxes) stored in Taesil of the Joseon Palace and classify the styles to discuss how these boxes have developed. By doing so, this study defined the archaeological styles of taesil seokhams in the chronological order. Although taesil seokhams are placed when taesil are first created, they do not have any texts engraved on them and it is difficult to gain information only from examining taesil seokham. However, Taejiseok(memorial stones buried in Taesil) and Agibi(gravestones buried in Taesil) were created along with taesil. These resources were examined and compared with literature records to find when each taesil seokhams was created. The critical elements to consider for the chronological arrangement were both the cover and container of the boxes and the transition of their style could be classified into four major stages. In detail, the Joseon Dynasty's taesil seokhams initially inherited the style of the Goryeo Dynasty to be formed into rectangular boxes. Through the transition of the mid and late 15th Century, the semi-circular cover with cylindrical container became the popular style in the late 15th Century. In the late 16th Century, the style of the previous period was further developed to add some decorative elements, such as projecting ornaments, but the ornaments were added for functional purposes rather than artistic purposes. However, the style went back to the semi-circular cover with cylindrical container in the early 17th Century. From the mid 17th Century, various styles appeared with ornaments only on the cover, cone-shaped cover with no ornament, or mortar-like container. However, a new style of cone-shaped cover with ornament emerged between the early and mid 18th Century and continued to stay until the mid 18th Century. In the mid 18th Century, the cover remained unchanged, but the container became a keyhole-shaped space with one side forming a "ㄷ" shape. However, in the late 18th Century, the most typical style of the semi-circular cover with cylindrical container reappeared to show that this is the most universal style. Last, in the mid 19th Century, the cover changed from semi-circular to rectangular with flat top. After this, the taesil seokhams began to disappear. In terms of style, it can be classified into four stages. In the early Joseon Dynasty, the taesil seokhams were underdeveloped and inherited the style of the Goryeo Dynasty (Stage I; 1401~mid-15C), but Joseon's unique style began to develop from the late 15th Century (Stage II; 1477~1641). After that, partial ornaments were added for adornment (Stage III; 1660~1754), but the typical style reappeared in the late 18th Century to finally degrade in the late Joseon Dynasty of the mid 19th Century (Stage IV; 1790~1874). This arrangement of style and chronology would greatly help archaeologists anticipate the time and owner of taesil seokhams even if only taesil seokhams are discovered without any records. * Tae(胎) : Placenta and umbilical cord * Taesil(胎室) : A facility(chamber) of burying Tae(胎) in rite when royal descendants are born.

21세기에 인류는 먹는 문제로 해서 어느 때보다 심각한 위기에 직면할 것이다. 유엔 식량농업기구(FAO)는 최근 세계 곡물재고량이 계속 감소되어 최소 안전기준인 소비량의 17%에도 못미치는 수준에 있으며 이미 북한을 비롯한 38개국이 극심한 식량위기에 직면해 있다고 경고하고 있다. 이같은 세계적인 식량위기 상황 속에 21세기 한국의 식량문제는 어떠하며 식량위기를 극복하기 위한 첨단기술의 현황을 점검해 보았다.

소음이 청기에 미치는 영향에 대해서는 서기 1세기 경부터 그 기록을 더듬을 수 있다. 1713년 Ramazini는 구리 세공자에게 소음을 방지하기 위한 귀 보호기 사용을 권하였으며, 이후 18세기 중엽 산업 혁명을 거쳐 1,2차 세계대전과 함께 20세기의 폭발적인 산업 발달에 맞추어 소음은 문명의 필연적 산물이 되면서 이에 대한 관심이 높아졌다. 우리나라도 경제 발전과 동시에 공장 소음, 자동차 소음등이 날로 심각해지면서 이에 대한 연구가 활발해지고 있으나, 국내외 모두 소음성난청의 치료 면에서는 뚜렷한 방법을 제시하지 못하고 있는 실정이다. 소음에 의한 난청은 일단 한번 발생하면 형태 및 기능이 불가역적이므로 예방만이 유일한 해결책이라고 하겠다.

근세에 들어오면서 과학은 산업. 정치의 전반적인 문제와 얽히고 그 영향으로 물리학. 수학이 발달하게 된 계기가 마련되었다. 수학연구는 16세기가 끝나면서 그 당시의 과학 ,기술적 요청에 따라 이탈리아 .독일 등 유럽에서 활발히 움직였다 17세기 '뉴턴의 만유인력의 법칙'등 5대 발견을 계기로 새로운 수학의 시대를 열었으며 18~19세기의 산업혁명과 근대 자본주의 형성 등 사회적 대변동이 근대수학의 새로운 체계를 이루는 산실이 되었다.

In this paper, I review the origins, activities, and influences on the future mathematical development of the Analytical Society of Cambridge. The story of the late 18th century Scotland mathematicians and the early 19th century Cambridge mathematician such as Woodhouse, and the Analytical Society's history show that the Analytical Society wasn't a completely new and reformative meeting. This article reveals that the new analytical studies developed characteristically in Britain's specific intellectual and social context of the late 18th century and the early 19th century.

The purpose of this study is to identify differences in the formative characteristics and system of Jobok by comparing the three relics Ui, Sang, and Daedae, which comprised Jeon-Sik's Jobok, with the data in the literature and five excavated Jobok relics, Sin Kyung-yu, Kwon-Woo, Hwasan-Gun, Milchang-Gun, and Lee Ik-jeong, from the 17th and 18th centuries. Jeon-Sik'sJobok was designated as a Gyeongbuk tangible cultural heritage, Sangju JeonSik Jobok and Crafts, in 2021. The three components of Jeon-Sik's Jobok are valuable as historical data since they are the oldest relics confirming colors. Regrettably, the edging fabric of the Ui made of red twill was mostly lost, with only traces remaining. Based on records, it was presumed that the edging fabric was black. It was confirmed that white decorative lines were yet to be used. In Jeon Sik's Sang, only the three front widths and one rear width remain, but the shape of the four rear widths can be inferred, and the creases were held only at the waist. Eighteenth-century Sang was connected at intervals at the end of the waist. Seventeenth-century Sang was connected with a slight overlapping of the rear Sang below the front Sang; therefore, it is assumed that Jeon Sik's Sang was also connected by overlapping the rear by more or less than 5cm below the front. After Hwasan-gun, the Sang was first made using black lines, then white lines were inserted, and, finally, it was pleated from the waist to the hem. The Daedae made the Yo and the Sin by folding the corners to form a 冂 shape with a single long band. The white Ju(紬) and the green yumunsa were used for the Daedae and the edges. This matches the color of the Daedae seen in the Jobok portraits of Milchang-gun, Lee Ik-jeong, and Jeong Hwi-ryang from the 18th century. In the 17th century, the Daedae made the Yo and the Sin by folding a long band like the Daedae of Jeon-Sik. After the 18th century, the Yo and the Sin were made separately and connected. To tie the Daedae to the waist, thin straps were attached at both ends. The relics of Jeon-Sik can be evaluated as reflecting the 17th-century Jobok system in terms of color and shape. Furthermore, it can be said that they are important historical data complementing the insufficient or inaccurate records of the Gukjoolyeui-seolye and Gyeongguk-daejeon.

Skull base height increases significantly with better nutrition and health conditions. With coordinate caliper or by subtraction, skull base height is easily measured. To examine nutrition and health condition of MIA(missing in action) during the Korean War and people who lived during the 17-18 centry of the Late Chosun. This study is focused on the change of skull base height through time as seen in comparing 83 MIA cranium and 12 17-18 centry cranium of Korea with 219 modern American middle class adult cranium(Terry Collection and forensic skeleton). To sum up, nutritional condition of MIA is not significantly changed, as seen in comparing with nutritional condition of 17-18 century people.

원시 인간들은 깊은 계곡이나 내륙 들판에만 살다가 약 8천년 전인 신석기 초부터 바다에 접근하여 바다를 이용하면서 살기 시작했다. 바닷물은 왜 짜고 바닷물은 왜 줄지 않는가. 17세기에 이르러 해양지배의 중요성이 인식되기 시작했고 1662년 영국 학술원이 창립되면서부터 해양의 특성을 관측하기 시작했다. 19세기 중반들어 바다의 신비가 풀리면서부터 정규 해양학이 탄생한 것이다.

유사량 조사는 최초로 17세기 초에 이태리에서 실시하였으나 기본 이념이 과학적으로 실시되기는 18세기에 이르러 불란서에서 양적인 유사량을 측정한 것이 처음이었다. 최근에 와서 Linsley(1958)는 상류에서 하류로 유하되는 유사의 60~65%가 하천에서 침전되고 나머지는 유하된다고 하였다.
