Pellinus linteus has been used for the prevention of cancer traditionally. There are three origins of Pellinus linteus, Korea, China and Cambodia. However, their immunological activities were not evlauated comparatively. Thus, this study was done to evaluate immunomodulatory effects of Phellinus linteus(PL) from Korea, china and cambodia, We confirmed PL showed two major protein bands, 50 kDa and 80 kDa by protein analysis. These PL effectively upregulated the expressions of IL-2 at 10 ug/ml and GM-CSF, IL-4, IL-10, IL-12(p35), IL-12(p40), IL-18, IFN-r in all concentrations. However, Korea-PL upregulated the expression of IL-12 more effectively than the other PLs. It intended to increase NO with no significance. Those results indicate Phellinus linteus had cytokine modulating effect

Peanut is an allotetraploid derived from a single recent polyploidization. Polyploidization has been reported to have caused significant loss in genetic diversity during the domestication of cultivated peanuts. Single nucleotide polymorphism (SNP)-based markers such as cleaved amplified polymorphic sequences (CAPS) derived from next-generation sequencing (NGS) have been developed and widely applied for breeding and genetic research in peanuts. This study aimed to identify the genetic diversity and population structure using 30 CAPS markers and 96 peanut accessions from five different origins. High genetic dissimilarities were detected between the accessions from Korea and those from the other three South American origins generally regarded as the origin of peanuts, while the accessions from Brazil and Argentina presented the lowest genetic dissimilarity. Based on the results of the present study, accessions from Korea have unique genetic variation compared to those from other countries, while accessions from the other four origins are closely related. Our study identified the genetic differentiation in 96 peanut accessions from five different origins, and this study also showed the successful application of SNP information derived from re-sequencing based on NGS technology.

Molecular analysis has been done for characterization of the interactions between three beet curly top virus (BCTV) strains and two Arabidopsis ecotypes in terms of virus inducible disease symptoms and infectivities. The total DNA was isolated from three tissues (shoot tips, infection origins and roots) of virus infected plants and this DNA was analyzed by quantitatively and qualitatively to elucidate virus movement and symptom development. CTV-Worland infected Col-O and Sei-O showed only symptom shown in hypersusceptible ecotype Sei-O by BCTV-worland was shoot tip stunting. Kinetics of virus DNA accumulation of three different viruses indicated that roots contained more virus DNA than shoot tips or infection origins, and that disease symptom severity was strongly correlated with virus DNA accumulation. These results suggest that the mild and Worland-specific symptoms shown in Sei-O by BCTV-worland are caused by the interactions of host factors provided by hypersusceptible ecotype and viral factors of mild strain.

This study started with the awareness that the review of the historical origins of Korean broadcasting will be of great significance in exploring the future of Korean broadcasting, and examined the various "origins" of Korean broadcasting - colonial, Cold War, totalitarian, neoliberal. Based on the theoretical background of "media archaeology", the historical 'origin' of Korean broadcasting was applied to track the origin of Hallyu(the Korean Wave) in the 21st century by comprehensively examining the political and economic motives of the time, the state's situational awareness of problems, major broadcasting policies and broadcasting realities. As a result of the study, it came to the tentative conclusion that the historical origin of the Hallyu, which began to be formed in the 1980s, originated from the three origins of Korean broadcasting and the "synthetic mixture" in the subsequent development process.

According to Wayne A. Wiegand in the 1998, he research to The "Amherst Method": The Origins of the Dewey Decimal Classification Scheme. Although a debate about the origins of the Dewey Decimal Classification Scheme has been going on for generations, historical consensus remains elusive. This paper contributes information to the historiography on the origins of the scheme: 1) by grounding an account of Dewey's thinking as he was crafting the DDC on an analysis of a large body of sources than previous classification historians have consulted; and 2) by expanding and deepening historical understanding of the contextual forces influencing on the classification structure. Because the DDC idea as it first occurred to M. Dewey in Amherst in 1872-73 is an important in the history of library development in the world. He outlined the first draft of his decimal scheme and submitted it to the Amherst College Library Committee on 8 May 1873. This paper analysis to "Three Genetic Paper", that is 1) The Merits of the System, 2) Library Classification System, 3) Its Special Adaption to our Library.

Little research on sensory study has been conducted from a marketing perspective and most of sensory studies have been done from a science perspective. Thus, this study examined wine sensory perceptions in the consumers' minds, which is how wine consumers associate grape variety Shiraz/ Syrah by the three different region of origins with specific sensory images. Total 234 questionnaires were collected from online wine community members at restaurants in Korea. The main results show that the most two shared sensory images of Shiraz/ Syrah were 'Dry' and 'Fruity' across the three region of origins. For Barossa Shiraz, the unique images were mainly found in Aroma image category such as 'Chocolate', 'Prune', whereas for Rhone Syrah, the unique images were mainly revealed in Overall image category e.g. 'Deep', 'Fascinating'. Additionally, this study confirmed that Maipo Valley is not recognizable region of origin of Shiraz/ Syrah. This study employed a free choice, Pick Any and conducted correspondence analysis to find out the degree of associations of sensory images and each region of origin.

Relationship between growth rate and wood quality was investigated by mechanical properties with Alnus glutinosa L. (24 years old) from 4 different origins of seeds (Bulgary, Italy, United Kingdom and Yugoslavia). Compression strength was in the range of $231{\sim}326kgf/cm^2$, and there was some differences among different origins of seed. Wood cultivated from the seeds of Italy, United Kingdom, and Bulgary showed higher growth rate and had lower compression strength and compression young's modulus. Wood from Yugoslavia seed had the fastest growth rate with higher strength than other three origins of seed. Bending strength was in the range of $426{\sim}727kgf/cm^2$, and there was some differences among the origin of seed. Higher growth rate wood showed higher bending strength and young's modulus than other woods. Trees cultivated from Yugoslavia seed had two times in diameter than other different origins of seeds, also have compressive strength, bending strength than other origins, which can be recommended as best cultivar in Alnus glutinosa L.

The aim of this study was to clarify the origins of grubs which were used in the experiments, and to determine many other effects that are now written in the classical medical and herbal books. We compared the efficacy of grubs written in the herbal and medical books on the one hand, and studied the origins of grubs used in the experiments, on the other hand. The following results were obtained. There are three kinds of grub species for medicinal uses. Holorichia diomphalia Bates mainly produced in China, Cetoniidae species mainly produced in Korea, and Protaeria brevitarsis in Korean folk remedy are three species. Grubs were used in 25 experiments. Of these experiments, Holotrichia diomphalia were used 12 times, Larve of Protaeria brevitarsis 3 times, and Protaetia orientalis was used once. So, of total 25 experiments, 36%(9 experiments) did not clarify the origins of grubs used in the experiments. Currently, the grubs, which are imported from China and used in Korea, are Holotrichia diomphalia Bates from China. Current experimental study shows that grubs have efficacy for protecting liver. So the use of grubs in folk medicine is believed to be based on the scientific evidence. Efficacy of grubs, though it is not recorded in the medical books, has the effects of anti-cancer(anti-tumor), antioxidant, and anti-diabetes mellitus. The ingredients of Holotrichia are protein, peptide, fat, enzyme, mineral, and other several nutrients. Study on the grubs so far has a tendency to be done with little focus on the differen of origin of grubs. So, from now on, it needs that the origin of grubs be clarified, and the study on the efficacy from each origin be done. Considering the effects that the classical herbal books have recorded, it is necessary that more profound study proceed to prevent and treat diseases on eyes and ears, on the basis of the fact that grub has multiple ingredients to replenish the vital essence.

This study aims at generating a continuous map by coordinates transformation between cadastral maps with different surveying origins. The continuous cadastral map is useful in various fields of GIS. For this purpose, an experimental study was conducted at Osan-Si, Kyonggi Province in cooperation with related institutions. In this study, three control point zone, large, medium, and small zone were to!;ted. For each control point, the currently used data were compared with the data at the surveyed time. About coordinate transformation method, we tested Helmert, Affine, and Polynomial methods which are the most representative among 2-dimensional coordinate transformations. These three transformation methods were evaluated according to variation of transformed parcel shape and agreement with neighboring areas. As the result of the evaluation, Affine transformation in large zone is the most appropriate coordinate transformation method fer Osan-Si.

Rapid geographical classification of Bupleuri Radix is important in quality control. In this study, near infrared spectroscopy (NIRS) combined with supervised pattern recognition was attempted to classify Bupleuri Radix according to geographical origins. Three supervised pattern recognitions methods, partial least square discriminant analysis (PLS-DA), quadratic discriminant analysis (QDA) and radial basis function support vector machine (RBF-SVM), were performed to establish the classification models. The QDA and RBF-SVM models were performed based on principal component analysis (PCA). The number of principal components (PCs) was optimized by cross-validation in the model. The results showed that the performance of the QDA model is the optimum among the three models. The optimized QDA model was obtained when 7 PCs were used; the classification rates of the QDA model in the training and test sets are 97.8% and 95.2% respectively. The overall results showed that NIRS combined with supervised pattern recognition could be applied to classify Bupleuri Radix according to geographical origin.
