  • In this study, the load of the river was calculated by using the actual data of the Yeong-bon C1, Yeong-bon C2, Yeong-bon C3 monitoring points of the Yeong-san river watershed to determine the excess. As a result, the BOD is 75.83 % at the Yeong-bon C1 and the five-year average value is higher than at other points. The Yeong-bon C3 was 72.15 % and Yeong-bon C2 was analyzed as 68.78 %. The five-year average of the T-P was 71.95 % for the Yeong-bon C2 and 69.86 % for the Yeong-bon C3 and 69.16 % for Yeong-bon C1; these levels exceeded the target water quality standards of 50 %. As a result of analyzing the pollutant load, we found that the Yeong-bon C1 has been highly affected by the nonpoint pollution source because the excess rate is high in the upper section of the flow rate. The Yeong-bon C2 showed a high excess rate in the lower part of the flow rate, and it was estimated that the influence of the point pollution source was large. The excess rate of the Yeong-bon C3 is small in the interval deviation, and it was evaluated as being affected by both point and non-point pollution sources. The TMDL monitoring network data were used to estimate the exceed ratio for the target water quality assessment, and the implementation evaluation was made by the flow exceedance probability interval to analyze the monitoring data so that the data could be utilized according to the purpose of the measurement network.

  • In the late Joseon Dynasty, the floor of the royal palace was covered with grass mat called ji-ui. Ji-ui was produced by connecting several mats named seokja(席子) and trimming the edge with narrow fabric named seon(縇). The standard manufacturing technique was to connect the shorter sides of the seokjas by overstitching them. A room was covered with either single or multiple ji-uis, depending on the case. In the case of the main and the subsidiary halls (jeong-jeon and pyeon-jeon, respectively) where the king conducted official meetings with the civil servants, multiple ji-uis were laid out to signify the division of space, which reflected the ceremonial aspects of the governing acts. The most essential division was the distinction of yeong-wae(楹外) and yeong-nae(楹內), with the jeon-goju (a tall frontal pillar inside the hall) functioning as the breakpoint. Jeong-jeon was divided into four spaces each covered with one ji-ui: yeong-nae, yeong-wae, and the left and the right sides of the royal seat named jwa-tap(座榻). Pyeon-jeon was covered with three ji-uis that divided the hall into three spaces: yeong-nae, yeong-wae, and hu-twae(後退) (the hind section) where the royal seat was placed on.
