To understand how to efficiently observe the biomass and community of phytoplankton, phytoplankton sampling was carried out from June to October 2019 at the Yeongju dam sediment control reservoir (YJ) and Bohyeonsan dam reservoir (BH1 and BH2). The results derived from microscopic observation, such as the conventional phytoplankton qualitative/quantitative analysis, and from the CHEMTAX method based on the pigments, were compared. The relative contribution of phytoplankton, calculated by the microscopy and CHEMTAX methods, showed a significant difference in all four classes: cryptophyta, chlorophyta, cyanobacteria, and diatoms. In addition, the correlation between the two observation methods was poor. This might be caused by methodological differences in microscopy that do not consider the varying cell sizes among phytoplankton species. In this study, by converting the cells into carbon, the slope between both carbon biomasses based on microscopy and CHEMTAX was improved close to the 1 : 1 line, and the y-intercept was closer to 0 for cryptophyta and diatoms. For cyanobacteria, the slope increased, the y-intercept decreased, and the plot approached 1 : 1 although the correlation coefficients were not improved in all classes. The present study suggests that application of CHEMTAX based on pigment analysis could be a possible approach to efficiently determine the relative carbon proportions of individual classes of phytoplankton community composition.

기본적으로 형 음 의 삼요소를 갖추고 있는 것을 문자라 칭한다. 이러한 문자는 보통 독립 성을 갖고 단독으로 사용된다. 하지만 모든 문자가 다 독립적으로 사용되고 있는 것은 아니 다. 어떤 문자는 독립적으로는 사용되지 못하고 다른 문자와 결합하여 字素를 이루어야만 사 용될 수가 있는데, 이를 ‘비독립 자소’라 부른다. 본 논문은 不成文 字素를 포함해說文解字 540개 부수를 대상으로 문자의 단독 사용 여부에 따라 비독립 자소를 구별해 내었고, 이를 다시 字形에 따라 독체자소, 합체자소, 그리고 변이자소로 분류하였다. 그리고 이들이 어떠한 과정을 거쳐 독립 자소에서 비독립 자소로 변하게 되었는지에 대해 심층적 분석을 진행하였 다. 그래서 비독립 자소가 어떠한 형태와 유형으로 대체되었는지, 왜 그러한 현상이 생기게 되었는지 등에 대해 분석하여 ‘不成文’, ‘通假’, ‘同義 문자’, ‘後起字’, ‘字形의 변형’, ‘釋形之誤’, ‘기타’의 7가지 유형으로 분류해 내었다. 아울러 이들의 문자로서의 가치와 위상에 대해서도 논하였다.

In this research, we were prepared the glazed ceramic samples by the change of the pigment content and investigated to reveal the standardized color. The chemical composition of the pigment was analyzed using a ICP-OES. XRF mapping and UV-Vis spectroscopy were used to evaluate the color property and surface homogeneity. The color development was observed as a result of analyzing the pigment content and change of the color. The pigment content and the spectral reflection showed the relation of the inverse proportion and the standardized color which could be revealed through analysis data.
