  • Panax ginseng root has been used as a major source of ginsenoside throughout the history of oriental medicine. In recent years, scientists have found that all of its biomass, including embryogenic calli and flower buds can contain similar active ingredients with pharmacological functions. In this study, transcriptome analyses were used to identify different gene expressions from embryogenic calli and fl ower buds. In total, 6,226 expressed sequence tags (ESTs) were obtained from cDNA libraries of P. ginseng. Insilico analysis was conducted to annotate the putative sequences using gene ontology functional analysis, Kyoto Encyclopedia of Genes and Genomes orthology biochemical analysis, and interproscan protein functional domain analysis. From the obtained results, genes responsible for growth, pathogenicity, pigments, ginsenoside pathway, and development were discussed. Almost 83.3% of the EST sequence was annotated using one-dimensional insilico analysis.

  • Ginseng (Panax ginseng C.A. Meyer), one of the most widely used medicinal plants in traditional oriental medicine, is used for the treatment of various diseases. It has been classified according to its cultivation environment, such as field cultivated ginseng (FCG) and mountain cultivated ginseng (MCG). However, little is known about differences in gene expression in ginseng roots between field cultivated and mountain cultivated ginseng. In order to investigate the whole transcriptome landscape of ginseng, we employed High-Throughput sequencing technologies using the Illumina HiSeqTM2500 system, and generated a large amount of sequenced transcriptome from ginseng roots. Approximately 77 million and 87 million high-quality reads were produced in the FCG and MCG roots transcriptome analyses, respectively, and we obtained 256,032 assembled unigenes with an average length of 1,171 bp by de novo assembly methods. Functional annotations of the unigenes were performed using sequence similarity comparisons against the following databases: the non-redundant nucleotide database, the InterPro domains database, the Gene Ontology Consortium database, and the Kyoto Encyclopedia of Genes and Genomes pathway database. A total of 4,207 unigenes were assigned to specific metabolic pathways, and all of the known enzymes involved in starch and sucrose metabolism pathways were also identified in the KEGG library. This study indicated that alpha-glucan phosphorylase 1, putative pectinesterase/pectinesterase inhibitor 17, beta-amylase, and alpha-glucan phosphorylase isozyme H might be important factors involved in starch and sucrose metabolism between FCG and MCG in different environments.

  • The objective of this study was to develop a Web based learning environment for Home Economics Education(HEE) using ICT (Information & Communication Technology). For the study, the following procedures were performed: 1) the review of literature, 2) development of teaming environment and questionnaires based on Web for HEE using ICT. The Web based learning environment was investigated and designed, and evaluated by the users. The problems indicated through the evaluation were revised and complemented. In addition, 13 sets of Learning questionnaires, which were verified using the same procedure as above, were developed to provide problem solving ability through the Web based learning environment. Learning environment based on the Web entitled "Together with the classroom of HEE" has a main menu, which is composed of rooms for HEE, students, teachers, various topics, recommendation sites, chatting, and e-mail. A room for HEE, in which teaming activity mainly occurs by following the sequences of learning procedures, includes other sub-rooms for the guidance of Loaming, discussion, directories for reference, question and answer, submission of homework, evaluation, and an encyclopedia. Therefore, this study implicates: 1) achievement of teaming environment using the ICT mainly made by students who solve problems closely related to daily life, 2) development of practical learning questionnaires fitted in the present state, 3) preparation for the curriculum. Finally, from this study, I suggested that further studies are needed to develop models for learning, interaction between students and teachers, and the learning materials under the Web based loaming environment.

  • A recent report of the Korean Intellectual Property Office(KIPO) showed that the number of biological sequence-based patents is rapidly increasing in Korea. We present biological features of Korean patented sequences though bioinformatic analysis. The analysis is divided into two steps. The first is an annotation step in which the patented sequences were annotated with the Reference Sequence (RefSeq) database. The second is an association step in which the patented sequences were linked to genes, diseases, pathway, and biological functions. We used Entrez Gene, Online Mendelian Inheritance in Man (OMIM), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Gene Ontology (GO) databases. Through the association analysis, we found that nearly 2.6% of human genes were associated with Korean patenting, compared to 20% of human genes in the U.S. patent. The association between the biological functions and the patented sequences indicated that genes whose products act as hormones on defense responses in the extra-cellular environments were the most highly targeted for patenting.

  • In this study, the global proteome of the IPEC-J2 cell line was evaluated using ultra-high performance liquid chromatography coupled to a quadrupole Q Exactive Orbitrap mass spectrometer. Proteins were isolated from highly confluent IPEC-J2 cells in biological replicates and analyzed by label-free mass spectrometry prior to matching against a porcine genomic dataset. The results identified 1,517 proteins, accounting for 7.35% of all genes in the porcine genome. The highly abundant proteins detected, such as actin, annexin A2, and AHNAK nucleoprotein, are involved in structural integrity, signaling mechanisms, and cellular homeostasis. The high abundance of heat shock proteins indicated their significance in cellular defenses, barrier function, and gut homeostasis. Pathway analysis and annotation using the Kyoto Encyclopedia of Genes and Genomes database resulted in a putative protein network map of the regulation of immunological responses and structural integrity in the cell line. The comprehensive proteome analysis of IPEC-J2 cells provides fundamental insights into overall protein expression and pathway dynamics that might be useful in cell adhesion studies and immunological applications.

  • This study compared the figures of viscera (臟腑圖) in the seventh volume titled "Body" of Sancaituhui (三才圖會), the illustrated Encyclopedia published in the Ming Dynasty (明代), and the figures of viscera in Leijingtuyi (類經圖翼). One hundred and six volume Sancaituhui was compiled by Wang Qi (王圻) and his son Wang Siyi (王思義) in the Ming Dynasty. It was first published in 1607 and republished in 1609. Sancaituhui is somewhat different from other existing medical books in terms of form and content. Thus, this study examined the difference. Another comprehensive medical book, Leijingtuyi, was written by Zhang Jing-yue (張景岳) in 1624. Both Sancaituhui and Leijingtuyi were published in China before Terrenz's Taixirenshenshuogai (泰西人身說槪), the book which first introduced Western anatomy. Therefore, this study accessed the two medical books to examine the development of figures of viscera before the instruction of Western medicine.

  • North-South Korean information technology(IT) terminologies are going to be gradually changed differently as the time is flowed. In accordance with the age of advanced information science and technology, the IT terminologies should be mutually identified and confirmed on the basis of ISO2382 Korean standardization being set up for the international IT terminologies made by the scholars both Republic of Korea(ROK) and Democratic Peoples' Republic of Korea(DPRK). In the present study, the results of mutual efforts on IT standardization since 1994 has been firstly analyzed systematically for the advanced North-South Korean IT terminology. Secondly, the differences of the IT terminologies used currently in both ROK and DPRK have been also analyzed and classified in the three categories. Thirdly, the current IT terminologies used in both ROK and DPRK have been summarized on the basis of "Encyclopedia of 21 Century Computer Terminology." Fourth, it has been finally set up the construction scheme of conceptual system on compiling operations for the dictionary of North-South Korean IT terminologies.
