This paper is designed to erudite theoretical guidelines of the Project of Standardization for Cataloging Korean Historical Manuscripts (古文書整理標準化硏究). The writer examines what made this project necessary and attempts to investigate some characteristics in contents of the Korean Historical Manuscripts as one of the underlying researches for the project. In this paper, the title and designation of each manuscript are mainly dealt with. They are fallen broadly into the two categories; manuscripts written in previous periods of the ChoGn dynasty and those of the Chosdn dynasty. The Chosdn manuscripts, in particular, are divided into the two kinds of documents of whether they were written before the issuing of The Chosdn National Me ,Ky?ngnuk-taej?n(經國大典) or not. Though the unified titles of documents made before issuing The Chosiin National Code are not clearly acknowledged, those of official documents written after the issue were codified in the Articles of Rites (禮典) of The Chosdn National code. The official documents have not their own specific titles in general, however, it is not hard to entitle them because official documents were merely designated according to the Articles of Rites. This paper explores the titles of documents both official and in-official, and points out the causes to make them confused. The writer suggests the following guidelines in cataloging historical manuscripts; several important stages handling Korean historical manuscripts include deciding their accurate terms and classifying them as well. In the case of designation, various titles and types showed in documents with the same contents should be generalized as a unified title, which covers throughout the periods. In other side, each title of documents that has been most frequently appeared should be accepted as the unified one, which includes similar contents with the original documents. Therefore, the tablet of the unified titles may be corrected when all guidelines mentioned before will be deeply discussed. It is reasonable that historical manuscripts are classified on the basis of their contents, and the designations of classified documents are determined in the context of today`s concept.

Objectives of this study were to monitor the distribution of heavy metals, to compare extractable heavy metal with total content and to investigate the relationships between soil physico-chemical properties and heavy metals in orchard soil. sampling sites were 48 in Gyeonggi, 36 in Gangwon, 36 in Chungbuk, and 44 in Chungnam. Soils were collected form two depths, 0 to 20 and 20 to 40 cm (here after referred to as upper and lower layers) from March to May in 1998. Total contents of heavy metal in soils were analyzed by ICP-OES after acid digestion (HNO₃:HCl:H₂O₂) whereas extractable contents were measured after successive extraction of 0.1 N-HCl, 0.05 M-EDTA, and 0.005 M-DTPA. Mercury was analysed by mercury atomizer. The average contents of Cd, Cu, and Pb in the extractant with 0.1 N-HCl at upper layer were 0.080, 4.23, and 3.42 ㎎/㎏, respectively. As content in the extractant with 1 N-HCl was 0.44 ㎎/㎏, and total contents of 20, Ni, and Hg were 78.9, 16.1, and 0.052 ㎎/㎏, respectively. m e ratios of concentrations of heavy metals to threshold values (Cd 1.5, Cu 50, Pb 100, Zn 300, Ni 40, Hg 4 ㎎/㎏) in soil Environmental Conservation Act in Korea (2001) were low in the range of 1/2.5-1/76.9 in orchard soils. The ratios of extractable heavy metal to total content ranged 5.4-9.21% for Cd, 27.9-47.8% for Cu, 12.6-21.8% for Pb, 15.8-203% for Zn, 5.3 -6.3% for Nii and 0.7 -3.6% for 2n, respectively. Cu and Pb contents in 0.05 M-EDTA extractable solution were higher than those in the other extractable solution. Total contents of Cd, Ni, and Ni in soils were negatively correlated with sand content, but positively correlated with silt and clay contents. Ratios of extractable heavy metal to total content were negatively correlated with clay content, but Zn and Ni contents were positively correlated with soil pH, organic matter, and available phosphorous. Therefore, the orchard soil was safe because the heavy metal contents of orchard soil were very low as compared to its threshold value in the Soil Environmental Conservation. Act However, it need to consider the input of agricultural materials to the agricultural land for farming practices for assessment of heavy metals.

Heavy metal contents in commercial horticultural growing media were investigated. Fifty-three samples were collected nationwide during 2000 to 2001 and heavy metals in the samples were analyzed by ICP-OES after acid digestion and 0.1 N HCl extraction. Average contents of total Cd, Cr, Cu, Ni, Pb, and Zn by acid digestion in the growing media were 0.69, 35.7, 14.9, 15.5, 12.7, and 54.8 ㎎/㎏ DW, respectively. The ranges of heavy metal in the growing media were 0-1.82, 0-259.8, 1.6-69.5, 0-60.7, 0-36.5, 12.9-124.0 ㎎/㎏ DW for Cd, Cr, Cu, Ni, Pb, and Zn, respectively. Heavy metal contents in the commercial horticultural growing media were showed lower levels than the permitted levels for quality control described by Korean Standard Analytical Method for Crowing Media. Average contents and ranges of 0.1 N HCl extractable heavy metals were 0.08 and 0-0.20 for Cd, 0.38 and 0-2.10 for Cr, 1.45 and 0-4.03 for Cu, 0.85 and 0-3.31 for Ni, 0.84 and 0-2.21 for Pb, and 30.68 and 0.18-88.45 ㎎/㎏ DW for Zn, respectively. These concentrations by 0.1 N HCl extraction showed much less levels than those of total heavy metals by acid digestion.

논토양중 카드뮴 유효도와 수도의 흡수이행에 미치는 석회 및 Humic acid 사용효과

This study was conducted to know the effect of lime and humic acid on cadmium availability and its uptake by plant grown in contaminated paddy soils with heavy metal. The treatment levels of lime were 2.5 and 5.0 ton/ha and that of humic acid were 1 and 2%. The contents of 0.1 N HCl extractable Cd were reduced with lime and humic acid and were negatively correlated with CEC as well as soil pH. The sequential extraction procedure was used to fractionate the heavy metals in soil into the designated from exchangeable (0.5 M KNO₃), water soluble (H₂O), organically bound (0.5 M NaOH), carbonate (0.05 M Na₂-EDTA) and sulfide/residual (4 M HNO₃). In soil amended with 2.5 ton/ha lime and 1% humic acid, chemical forms of Cd at tillering stage were predominant exchangeable+water soluble extractable Cd, whereas that at harvesting stage were predominant carbonate+sulfide/residual extractable Cd. The exchangeable forms of Cd in soil with lime and humic acid were negatively correlated with soil pH during the harvesting period. Total absorbed Cd of paddy rice tended to occur in the order of root > stem > leaf > brown rice. Cd con- tents of brown rice with lime and humic acid treatment were 0.09 and 0.08 mg/kg, respectively. That were lower than control, 0.20 ㎎/㎏. It could be that treatment of lime and humic acid in polluted soil by heavy metals would reduce the uptake of heavy metals by plants and be a temporary method of reclamation at the highly heavy metal contaminated soils.
