Yim Eon Kook was deeply involved in founding Chijongcheong(national tumor medical clinic), a government branch in charge of treating tumors mid-Chosun dynasty. He came to be famous nationwide for curing tumors well and when the royal family was notified of this, they founded the Chijongcheong to supply professional health care. He wrote books on treating tumors such as "chijongjinam" and contributed significantly to the advancement of the tumor treating during his times.

This study intends to investigate the processing of the bibliographic relationships in the MARC formats based on the analysis to the related cataloging rules. In the traditional cataloging rules, many methods are used to process the bibliographic relationships(vertical, horizontal, and chronological), including analytics, references, notes, and independent entry. Linking entry fields in the MARC formats have been introduced mainly to process the chronological relationship in the serials, but later expanded, as a chronological in MARC format, to include other relationships applied to all other materials. Comparative analysis on the linking entry suggests that there are rare differences between UNIMARC and USMARC formats except the terminology and display constants, and that it is desirable in the KORMARC and JAPAN MARC to introduce the linking entry more comprehensively.

This paper was investigated the changes of the cell wall components, enzyme activities during ripening of jujuba fruits for elucidating the softening metabolism of jujuba fruits. Firmness were decreased during ripening. Moisture content did not show any notable cahanges until ripening stage but they decreased a little In overripe jujuba fruits. Polygalacturonase activities were not detected at nature green stage and $\beta$-galactosidase activities were until turning stage. But polygalacturonase activities in ripening and overripening were 51.31 and 100.72 units/100g-fr, wt. respectively. $\beta$-galactosidase activities were 16.05 and 182.55units/100g-fr. wt. in the same stages. The content of water-soluble protein was increased in overripening. Stage the contents of cell wall and alcohol-insoluble material were. decraesed during maturation, but water-soluble material was increased. The pectin and alkali-soluble hemicellulose were increased until ripening stage, but decreased in overripe jujube fruits. The total pectin and insoluble pectin during ripening, but decreased in overripe jujuba fruits.

In this paper, a new type of active snubber was proposed to lower the excessive rated voltage of the clamp capacitor which was a problem in the conventional circuit by applying auxiliary winding into the active snubber. A simplified equivalent circuit of the proposed snubber was derived by applying it to QR flyback converter, and the equivalent circuits for each switch state was shown under the steady-state condition. In addition, the maximum voltage of the clamp capacitor as well as the main switch was found by using the steady-state equations. In particular, it was found that the clamp capacitor voltage could be controlled by the auxiliary winding ratio. In order to verify the utility and practicality of the proposed converter with auxiliary winding type active snubber circuit, a prototype with an output voltage of 19V and a maximum load current of 6A was produced and the results were reported.

This study set out to examine the variant forms in the Korean block-printed edition of YouYangZaZu(酉陽雜俎)n terms of modifications of writing forms, increase and decrease of strokes, shortening and lengthening of strokes, connection and interruption of strokes, replacement of Pyeonbang(偏旁), and changing structures and positions. The study also aims to investigate the frequent uses and characteristics of variant forms. The findings show that the variant forms of YouYangZaZu(酉陽雜俎) include characters in some parts. There are 1,500 variant forms in the Korean block-printed edition of YouYangZaZu(酉陽雜俎)ith numerous characters of both various modifications and increasing or decreasing strokes based on the same characters. There are mixed uses of block letters and variant forms throughout the book from a single form to ten different forms of a character.
