The measurement in ruling period of King Sejong in Chosun Dynasty remained unchanged compared with that of Goyeo Dynasty. But Hwangjongchuck, the basis of measurement was amended in the 7th year in ruling period of King Sejong, Juchuck, Youngchochuck, Cholegichuck in the 12th, and Pobeckchuck in the 13th. The record of Pobeckchuck first appeared in the true record of Chosun Dynasty in the 4th year in ruling period of Sejong, and first record on the amendment of the Pobeckchuck was found in the 13th year in his ruling period. The presentation of the comparison of Pobeckchuck with Cholegichuck in volume 128 of true record of Sejong makes help the estimation of the length of Pobeckchuck. To calculate one Chuck of Pobeckchuck with this measurement comes to 44.75cm in present measurement, and the length at this time had remained unchanged to Yeonsangun period. Important fact which was newly found in the true record of Chosun Dynasty was that Pobeckchuck had been used for diverse purposes. Pobeckchuck was used to measure width, length and thickness in manufacturing wardrobe. and also to measure cloth decorating wardrobe. This is the first record(4th year of reign of Sejong) showing that Pobeckchuck was first used to measure cloth in Chosun Dynasty The record shows that Pobeckchuck was also used to measure the length of circumference of castle for its construction. to measure distances between people, the length of hook of wooden handle, and the height of man.

The remarkable fact regarding the History of Chosun Dynasty(from Jungjong- Youngjo) is that any slightest evidence can't be found that Pobeckchuck was used to measure clothes or various Pobecks. There remains the document that in the 22nd years of Myeonjong, Japan required that Pobeckchuck be used, but it couldn't be allowed because of the reason it was made in the former king. This fact raises the high possibility that Pobeckchuck could be the most trustworthy standardized ruler at that time, and in other point of view, it can be presumed that the measurement in the period of King Sejong continued to have been used until this time. It can be seen that the length of one Chuck of Pobeckchuck at this time must have been equivalent to 46. 73cm of Pobeckchuck of Samchuck in the period of Sejong. In the History of Sunjo Period, many records on Pobeckchuck can be found, which fact seemed to have rectified the measurement system which was disordered by military revolt, though the reason is not clear. Also a record can be found that in the period of Sunjo, Chinese envoy required the Sunjo Regime to use Pobeckchuck for the measurement of copper pillar, which record supports the fact that Pobeckchuck is the standardized ruler. Another record that in the 26th period of Youngjo, Pobeckchuck of Samchuck was corrected according to the Kyeongkukdaejeon shows that the length of Pobeckchuck was 46.80cm at that time. Also, the record which rectified many rulers with the comparison of Hwangjong-chuck, Ju-chuck, Joryeki-chuck, Yongjo-chuck, etc. with one another reveals that the rulers used in the period of Sejong continued to have been used unchanged until in the period of Youngjo.

This study aims at defining the meaning of Pobeckchuck in the historical view-point, which appeared in the History of Joseon Dynasty, regarding the periods from the ruling period of Sunjo to that of Sunjong as the latter part of history. Pobeckchuck used in King Sejong was redressed in accordance with the measurement in the Kyeonggukdadejeon(code), in which time one Pobeckchuck was 46.80cm long. It is known that Juchuck, Hwangjongchuck, Youngjochuck, Joraegichuck etc. which had been used in the ruling period of Sejong Dynasty, were used till the period of Youngjo. Also, the document shows that in the 12th ruling period of Sunjo, Pobeckchuck was used for measurement, and in the 20th ruling period of Sunjo, newly-made ruler was only used for the measurement of fields, but no more details about how long it was. But according to the document complied at that time, one Pobeckchuck was 46.80cm long, which fact reveals that the same measurement was used as in the ruling period of Sunjo. When all the measurement laws which were established in the 3rd year of Junghee, the 6th year of Kwangmu were abolished, Pobeckchuck was solely banned from its use, which fact offers a glimpse of how confusing at that period was. The comparison and examination among many documents in the latter part of Joseon Dynasty show the differences within about 4cm that one Pobeckchuck ranged from 44.80cm to 48.80cm long. But no other document on measurement appeared in the History of Joseon Dynasty, except for the 46.80cm. Thus, the 46.80cm corrected in the ruling period of Sunjo proves that one chuck in Pobeckchuck adopted by the dynasty was used as the measurement of length till the ruling period of Sunjong.
