To find one side of the square equal to the area of a circle is an unsolved problem. Likewise, to think one side of the cube equal to the volume of a sphere is another unsolved problem. There are four methods to find the area of the circle and the volume of the sphere. This paper aims to weigh each method against the other in finding the answers of the problems in the Chosun Dynasty and investigate their own characters.

동일 주제를 대상으로 현시대의 것과 지난 수 백년 전 과거의 것을 서로 비교하는 연구는 차이점을 발견할 수 있으리라는 기대감 하나 때문만이라도 흥미를 갖게 한다. 본 논문은 $\boxDr$국역 조선왕조실록$\boxUl$ 과 $\boxDr$국역 고종순종실록$\boxUl$ (서울 시스템간) 및 인터넷을 검색하여 과거 1934년 간의 우리나라 강설현상을 추적하여 그 특징을 정리하여 본 것이다.(중략)

Korean ginseng (Panax ginseng) has been known as one of the representative special and healthful products originating from Korea for 4500 to 5000 years. The word of ginseng was first mentioned in JiJuZhang(急就章), written by ShiYou during the reign of King Yuah Di of the Chien Han Dynasty, China (33-48 BC). It has been known that wild Korean ginseng grows in Korean peninsula including Manchuria and the ginseng is found only between the $33^{rd}$ and $48^{th}$ parellels of north latitude. Since the times of three kingdom in Korea at 4-7 century, which is Kokuryo, Baekje and Shila, Korea has been the chief ginseng producing country. A large quantity of ginseng was exported from Korea to China for medicinal use at that times. That was written in SamGukSaGi(三國史記) by BuSik Kim of Koryeo Dynasty in Korea in 1145. The cultivation of Korean ginseng was also recorded in Bencaogangmu(本草綱目) written by LiShi Zen during the regin of the Ming Dynasty in 1596, China. The ginseng seedling, which was known as an original method invented by imitating the method of rice transplantation, appeared in the SeungJeongWon Ilgi(the diaries of the royal secretariat, 承政院日記), 1687 in the regin of King SukJong in Korea. It was suggesting that ginseng cultivation was firstly established in the early 1600s in Korea. On the other hand, red ginseng(written as 熟參) was reported firstly in GoRyeoDoGyeong(高麗圖經)(a record of personal experience in Korea, written in 1123) by SeoGung in Song Dynasty, China. The names of Pansam(written as 板蔘) and Pasam(written as 把蔘), which were the another types of red ginseng products, were came on in the JoSeon Dynasty Annals in 1552 and 1602, respectively. Although the term of red ginseng(Hongsam in Korean) was firstly appeared in the JoSeon Dynasty Annals in 1797, it is believed to have been developed a little earlier periods from the King Jungjong(1506~1545) to the King SeonJo(1567~1608) in Korea. Then, the Korean red ginseng has begun production on a large scale in SamJeong Department of NaeJangWon(內藏院 蔘政課) in the Korean Empire(大韓帝國) in 1899. More detailed records about red ginseng production method were written in the SohoDanag Miscellany(韶濩堂集) by Taekyoung Kim at 1916 year in Korea. On the while, the efficacy of ginseng was first recorded in Shennongbencaojing(神農本草經) written in China(BC 83-96) and the efficacy has been continuously inherited.

In this research, we have extracted historical records regarding the geotechnology from the Goryeosa and the Annals of the Joseon Dynasty which are rated as ancient books that have objective views in the Goryeo Dynasty and the Joseon Dynasty in order to understand the national awareness and the social situation of the past events. We used the Korean history database system of National Institute of Korean History (NIKH) and collected related records by searching specific keywords such as volcano, mining, hot spring, and meteorite. According to the historical records, geological events such as the volcano and meteorite were regarded as important issues which were enough to be recorded in annals and surveyed by the dispatched government officials to the fields of events. In case of the hot springs, government officials conducted explorations of hot springs at king's orders and developed the potential areas of hot springs. Among the historical records on mining, the contents of geotechnology including the contents about discovered minerals and its locations can be easily found from those ancient books. Especially, it is possible to understand the history of geotechnology such as an establishment of modern organizations and a capitalistic flow for development through the history of the mining in the late Joseon Dynasty.

The following demonstrates similarities between Japanese and Korean food culture. The facts have been discovered through the examination of records kept by Korean Communication Facilities and Japanese Envoys. Both countries used the numbers 7, 5, 3, in food treats. Both demonstrated Da do(茶道) style during banquet. Japanese Na-ra-dae(奈良臺) is similar to Korean Sue-bae-sang(壽杯床). Both countries had a Kan-ban(decorative table, 看盤) and Mi-soo(wine and someatables, 味數) during banquet. The composition of the table may be the same for both Korean Geo-sick-oh-kwa-sang and Japanese 3Jeup(soups) 15Che(dishes). Agasang is a Kan-ban(decorative table) of Choson's Da-do(茶道) style.

We arrange Korean ancient calendar with Solar calendar during Choseon Dynasty(A.D. 1392-1910). In this period, we have one representable history books and several books, and most of information for date are found from them, ChoseonWangjosillok(조선왕조실록) and Jeungbomunheonbigo(증보문헌비고), etc. In those books many astronomical data and calendar information data are contained, so we can make chronological tables. Most of the data are arranged based on those several books, and for doubtable data are identified from eclipse, historical events and lunar phase calculations etc. We find that arranged chronological tables during Choseon Dynasty are similar to that of China and somewhat different from that of Japan. In addition we summarize all misrecorded date data in ChoseonWangjosillok

King Gojong was the twenty-sixth King in the Choseon Dynasty. He took the throne when he was only 12 years old and had to set up regency for 10 years. During his period, situations were worsened in both domestic and foreign affairs. In the end, after 3 years from abdication of the throne, the Choseon Dynasty was overthrown in compliance with a coercion by Japanese empire. He died in 68 years old. We can assume that his inveterate disease are weakness of the spleen and the stomach. In addition, he suffered from a boil, a cold, dermatosis, eye disease, an external wound, dentistry disease, arthritis, etc. The official cause of his death was cerebral hemorrhage. But we assume that the possibility of poison murdering is high.
