Expressed sequence tags (EST) are help to quickly identify functions of expressed genes and to understand the complexity of gene expression. In order to analyze gene expression of the leaf development in Panax ginseng, which is one of the most important medicinal plant, expressed sequence tags (EST) analysis was carried out. We constructed a cDNA library using the immature leaf of Chunpoong. Partial sequences were obtained from 3,170 clones. The ESTs could be clustered into 1,624 (56.1%) non-redundant groups. Similarity search of the non-redundant ESTs against public non-redundant databases of both protein and DNA indicated that 1,137 groups show similarity to genes of known function. These ESTs clones were divided into sixteen categories depending upon gene function. Most abundant transcripts in immature ginseng leaf were photosynthesis related protein, such as chlorophyll a/b binding protein LHCII type I (128), chlorophyll a/b binding protein (53), ribulose-1,5-bisphosphate carboxylase (41), and photosystem I psaH (26). The EST data from immature leaf generated in this study is useful in dissecting gene expression in leaf organ of ginseng.

In order to study gene expression transcribted during the embryo development, we constructed a cDNA library of embryogenic callus induced from cotylendon of Korean ginseng and generated expressed sequence tags (ESTs) of 3,359 clones randomly selected. The ESTs could be clustered into 1,910 (59.1%) non-redundant groups. Similarity search of the non-redundant ESTs against public non-redundant databases of both protein and DNA indicated that 2,217 groups show similarity to genes of known function. These ESTs clones were divided into eighteen categories depending upon gene function. Most abundant transcripts were ribosomal protein small subunit 28kDa(40), tumor-related protein(35), metallothionein (31), small heat-shock protein class 18.6K(24), and cyclophilin(20). There are no useful informations of gene expression during the embryo development in Korean ginseng. These results could help to understand the embryo development in Korean ginseng.

Expressed sequence tags (EST) are help to quickly identify functions of expressed genes and to understand the complexity of gene expression. To assist genetic study of the root development in Panax ginseng, which is one of the most important medicinal plant, expressed sequence tags (EST) analysis was carried out. We constructed a CDNA library using the 4-year Chunpoon root. Partial sequences were obtained from 3,841 clone. The ESTs could be clustered into 2,056 (64%) non-redundant groups. Similarity search of the non-redundant ESTs against public non-redundant databases of both protein and DNA indicated that 1,498 groups show similarity to genes of known function. These ESTs clones were divided into eighteen categories depending upon gene function. The most abundant transcripts were major latex protein (41), ribonuclease 2 (36), metallothionein 2(35). Our extensive EST analysis of genes expressed in 4-year Chunpoong root not only contributes to the understanding of the dynamics of genome expression patterns in root organ development but also adds data to the repertoire of all genomic genes.

In this study, in order to expand the access points of reading materials, a reading material classification (RMC) system based on the facets of book use was devised. The facets of books that can be considered by book users in the reading situation were content-analyzed. Also, through network analysis, subject headings adjacent to one subject heading were grouped into related subject headings. The RMC developed in this study can be used as a tool that provides various access points to help book users search in the library OPAC and other reading information systems.

This study was to suggest the new rules for revision of KCR4 by comparing between ISBD consolidated edition and KCR4. The study methods was to compare the rules in each element after mapping the description elements in each area of ISBD and KCR4. Resultingly, first, content forms and media types must be included for describing resource types. Second, it is needed for rules about the common title and the dependent title. Third, it is needed for rules about "parallel" such as parallel title, parallel other title information, parallel statement of responsibility relating to title, parallel edition statement, parallel statement of responsibility relating to edition, parallel numbering system, parallel place of publication, production and distribution, et. al. Fourth, the rules about material or type of resource specific area must be regulated in terms of the contents of the resource. Fifth, the home country principle must be not applied in describing the place of publication, production and distribution for the consistency. Sixth, it is needed to regulate the extent, other physical details, dimensions, and accompanying material statement for all materials instead of the material description according to material types. Seventh, rule number of notes must be agreed to number of main rules. Eighth, it is needed for detailed rules about resource identifier. This study might be contributed to revise the KCR4.

The content systems of Shinjung Tongguk Yoji Sungnam(신증동국여지승람, A Korean Geography Published in Chosen Dynasty) consist of 26 items and the main subject comprises administration, military and geography, This book does not suggest a simple geography but a comprehensive bibliography as an administrative guide book of a nation or a military operation manual. In particular, this book is made much of as a more valuable material in elevating the quality of the geographic book since it contained a 'Cheyong(제영)' item and reinforced the fields of humanities which could not be found out in other geography. The verses of Cheyong are recorded in the documents in the Chungchong, Kyungsang and Chulla Provinces, and these recorded verses In the tree provinces are more than half of the whole country's. The objects of recitation in the these verses are related to such natural phenomena and historic relics as the mountains, the livers, the wails and the royal tombs.

Polyacrylate dispersion(emulsion) as adhesive material was superior in quality such as preservation characteristics and reversibility. The tapes for repairing archival documents manufactured with four different types of formulation resulted in pH 7~8.8, soluble solid 50~52%, and viscosity 1,300~2,500 cps. Sample 4 of those was most excellent. Probably, sample 4 included inorganic materials such as MgO, silica gel, and zeolite. For selecting carrier of tape, tracing papers, were applied for manufacturing tapes and tested for adhesive strength and peel strength. Adhesive strength of tracing papers, was 3.1~3.8(N/10mm), 2.2~2.8(N/10mm), and 1.7-2.3(N/10mm), respectively. Peel strength was similar in all samples. To determine characteristic of conservation to the selected carriers, stability of deterioration was examined at conditions of $105^{\circ}C$ and $80^{\circ}C$ 65% for 7 days.

This articles aims to analyze HOSEONGKONGSINLOK awarded to Kim Yang-bo, a eunuch, having major roles to take refuge the king Seon-jo when the Japanese invader rushed into Seoul in the time of Hideyoshi's Invasion of Korea in 1592. At that time, all meritorious retainer was to be rewarded equally by a given rules of the stipends and the gifts. But for the eunuch, differently from others, the portrait was not made to be handed down as a model. Instead one more clothes was given. This suggests that there were some differenciation of the class and the job in the evaluation of the merits. From this we can see that there might be some problems in the selection of the meritorious retainer, resulting in unfair awarding, and needing to be reevaluation from the historian. Even though somewhat worn out, this material has very important value as a historical source in terms of following viewpoint: 1) it contains all the name of the meritorious retainers at that time. 2) it suggests the social situation and affairs at that time more precisely. 3) it reveals the facts even some facts in the authentic records can be corrected.
