The geographical origins of raw ginseng (RG) were discriminated using an electronic tongue. Taste screening, DFA (discriminant function analysis), and CDA (canonical discriminant analysis) were used to statistically analyze the data. The taste profile patterns of umami, bitterness, and sweetness of the Korean RG was different from those of the Chinese RG. The Korean RG was stronger than the Chinese RG regarding the taste of umami. DFA discriminated the geographical origins of 154 samples, with a few overlapping samples, between the Korean and Chinese RG. CDA showed that the accuracy of origin discrimination for the Korean and Chinese RGs were 87.01 and 94.81%, respectively. The final accuracy of origin discrimination was 90.91%. The distance between the centroids of each group was 2.7463. Thus, the electronic tongue analysis can be used to efficiently differentiate the geographical origins of RG.

The present study was undertaken to compare the effects exerted by different extraction solvents on the extraction of active components, such as polyphenols and flavonoids, from the dried leaves of Artemisia annua L. Different extracts were prepared using a heating mantle. The extraction solvents used were distilled water, and 20, 40, 60, 80, and 99.5% ethanol solution. It was observed that the 40% ethanol solution yielded the most significant results in the extraction of various phytochemicals with phenol concentration of 154.8±0.28 mg of gallic acid equivalent/g and flavonoid content of 25.28±0.01 mg quercetin equivalent/g. However, based on the extraction solvent used, varying trends were observed in the antioxidant, enzyme inhibition, and bacterial inhibition analyses. It was concluded that the extraction solvent should be selected based on the purpose of use of the dried leaves of A. annua L.

A new Phalaenopsis cultivar 'SM 333' was bred by Sangmiwon Orchid, Korea, which produces young plants through tissue culture techniques. The new cultivar 'SM 333', showing the phenotype of multiflora with pink color and small, multibranching-type characteristics, was derived from crossing between Phalaenopsis 'Odoriko' and 'Be Tris'. An elite individual number '02-03-33' later termed 'SM 333' was selected among about 300 individual progenies, based on an intensive selection process covering vegetative and flowering distinctiveness over more than 2 years. In year 2004-2005, the 1st and 2nd characteristic analyses were carried out through performance and uniformity tests. 'SM 333' shows flower color that is bright clean pink (RHS # RP69D) and flower shape that is formal type with 5.0 and 5.8 cm in flower height and width, respectively. 'SM 333' is regarded as raceme flower type suitable for the small casual flower market. The leaves of 'SM 333' grow horizontally and about 20.8 cm in length and 6.5 cm in width. This cultivar also possesses no genetic variation, and is amenable to fast in vitro propagation and easy growth due to its vigorous growth habit. This 'SM333' was registered (Reg. # 2916) with Korea Seed & Variety Service (KSVS) on 1st December, 2009, and the plant breeder's right is currently controlled by Sangmiwon Orchid Company, Korea.

The analytical measurement range (AMR) is the range of analyte values that a method can directly measure on a specimen without any dilution, concentration, or other pretreatment not part of the usual assay process. The linearity of the AMR is its ability to obtain test results which are directly proportional to the concentration of analyte in the sample from the upper and lower limit of the AMR. The AMR validation is the process of confirming that the assay system will correctly recover the concentration or activity of the analyte over the AMR. The test specimen must have analyte values which, at a minimum, are near the low, midpoint, and high values of the AMR. The AMR must be revalidated at least every six months, at changes in major system components, and when a complete change in reagents for a procesure is introduced; unless the laboratory can demonstrate that changing the reagent lot number does not affect the range used to report patient test results. The AMR linearity was total protein (0-16.6), albumin (0-8.1), total bilirubin (0-18.1), alkaline phosphatase (0-1244.3), aspartate aminotransferase (0-1527.9), alanine aminotransferase (0-1107.9), gamma glutamyl transpeptidase (0-1527.7), creatine kinase (0-1666.6), lactate dehydrogenase (0-1342), high density lipoprotein cholesterol (0.3-154.3), sodium (35.4-309), creatinine (0-19.2), blood urea nitrogen (0.5-206.2), uric acid (0-23.9), total cholesterol (-0.3-510), triglycerides (0.7-539.6), glucose (0-672.7), amylase (0-1595.3), calcium (0-23.9), inorganic phosphorus (0.03-17.0), potassium (0.1-116.5), chloride (3.3-278.7). We are sure that materials for the AMR affect the evaluation of the upper limit of the AMR in the process system.

The objective of this research was to estimate the shelf-life of 4 kinds of Korean soup (Yukkaejang, Sagol-woogeojitang, Kalbitang, and Seolleongtang), under an accelerated experiment, based on the changes in the selected physico-chemical, microbiological and sensory characteristics. The 4 kinds of Korean soup (Yukkaejang, Sagol-woogeojitang, Kalbitang and Seolleongtang) were 1.sated at $121^{\circ}C$ for 30 min. and the shelf life was evaluatedthrough accelerated experiment, based on tile changes in the physico-chemical, microbiological and sensory characteristics. No viable cells were detected in any of the treatments and no significant differences were shown in pH, TBA and Hunter's color values for 3 weeks at $37^{\circ}C$. The periods found to be acceptable by sensory evaluation were 1 days for Yukkaejang and Kalbitang, 14 days for Sagol-woogeojitang, and 21 days for Seolleongtang. For an assumed $Q_10$ value of 2.5, shelf-life was predicted as 109 days for Yukkaejang and Kalbitang, 219 days for Sagol-woogeojitang, an d 328 days for Seolleongtang at $5^{\circ}C$, suggesting that these 4 kinds of Korean soup are suitable for commercial distribution.

We studied the anti-diabetic effects of medicinal herb water extracts on expression of hepatic glucokinase (GCK), pyruvate dehydrogenase (PDH), and acetyl-CoA carboxylase (ACC) mRNA. The medicinal herbs used for experiments were Cornus officinalis (CO), Paeonia suffruticosa Andrews (PSA), Discorea japonica Thunb. (DJ), Rehmannia glutinosa (RG), Lycium chinense (LC), and Pyrus pyrifolia (PP). For GCK mRNA expression, CO, RG, and LC water extracts exhibited a more effective activity than other extracts. Cells treated with RG and LC water extracts showed an increase in expression of PDH mRNA to 191% and 124%, respectively, compared to control. Expression of ACC mRNA was significantly higher in LC water extract. These data indicate that CO, RG, and LC water extracts stimulates expression of hepatic GCK, PDH, and ACC mRNA.

Purpose: We evaluated the level of pain and clinical presentation of calcific tendinitis after treatment with conservative and early arthroscopic operation. Materials and Methods: We reviewed 30 patients with calcific tendinitis with the minimum of 6 months of follow up period, treated from February 2002 to May 2008. We implemented Constant-Murley score to evaluate the pain of calcification and improvement of range of motion at the 2nd week, 12th week and 24th week with the patients who had treatment with steroid injection in 15 cases and operation in the other 15 cases. Results: Evaluating the level of pain using Constant-Murley score, we found that conservative treatment group had the scale of 3.2 before treatment and 13.6, 14.5 and 14.7 at 2nd, 12th, and 24th week, respectively since started treatment. The operation group, on the other hand, had the scale of 3.3 preoperatively and 10.2, 13.0, and 14.3 at 2nd, 12th and 24th week postoperatively. The range of motion in the conservative treatment group showed 14.3 on average before the treatment and 21.7, 31.3 and 35.7 at 2nd, 12th and 24th week after treatment. The operation group had 14.4 on average preoperatively, and 33.1, 35.8 and 36.4 at 2nd, 12th and 24th week postoperatively. The operation group had statistically significant improvement compared to the conservative group at the 2nd and 24th week, but showed no difference between the two groups at the final follow up. Conclusion: Early arthroscopic treatment of calcific tendinitis seems to be an excellent option that can increase the level of satisfaction of the patients and an efficient way of putting the patients back to their normal life promptly.

In the 17th and 18th centuries, when the Ryukyu kingdom had been invaded and controlled by Japan, some official texts about 'history' were documented. In that texts, there are some myths about the kings-Syunten(舜天), Eiso(英祖), Satto(察度), Syouhasi(尙巴志), Syouen(尙圓)-who founded dynasties of Ryukyu kingdom. This study attempts to delineate the features and meaning of those founder myths as a polotial discourse for kingship. The results of this study are as follows. 1. The founder myths are discourses to describe the genealogy of the Ryukyu kingdom as the result of Mandate of Heaven(T'ien Ming, 天命). 2. In ancient okinawa, the sun was a symbol of ruler. The king of Ryukyu kingdom was thought as 'son of the sun', 'Tedako(てだこ, 太陽子) in the time of Syou dynasty(尙王朝). But in the founder myths, the only one Tedako is Eiso. 3. In the myths, the 'historical' founders are described as the king for agriculture. They were said to make the farming instruments with iron and rule the spring water for farming. The iron and water for fariming was thought to represent the power of king and the kingship. 4. The writers of myths aimed to be separated from the mythical kingship of past Ryukyu(古琉球). So, they threw the idea of Tedako(=mythical kingship) into the prison of mythical ages by rewriting myth of King Eiso. Instead of it, they built up the new image of agriculture-king who rules and controlls the iron and water for good farming. The meaing of this change, from 'shiny sun' to 'cultural king', is that the abstract and general power of kingship was turned into a concrete and restricted power of kingship. On the bases of it, there was the confucian political ideas from China, T'ien Ming thought(天命論). Under the influence of not only China but also Japan, the writers of myths attempt to find a new way for their kingdom by reconstructing kingship with ruminating over the kingship of past. The myth of founders in the 17th and 18th Centuries shows the aspects of kingship of Ryukyu kingdom and tells us that those myths are the political discourses identifying kingship and Ryukyu kingdom.

Today's digital culture has been realized through various media, and even now, is changing and growing. If the previous digital culture was actualized through technologies such as the Internet, mobile devices etc., today it includes even things that give new life to contents using various medialike this. The moment this digital technical aspect is grafted into culture, a new genre called 'Cultural Contents' is born. Such cultural contents can be seen as a way for classics to approach people in a digital world that is evolving fast like today. To make classics into a cultural content, its basic narrative structure is important. Classics contain the history at the time, the awareness of people who lived at the time and the detailed rite of passage people experienced. This point can be interpreted as classics not just a cultural heritage of the previous era, but having the functionality that can form a consensus of modern people. This thesis views our classic novels of Mongcha group such as 'Guwunmong' and 'Okrubong' as a potential subject of cultural contents, and the problem of how it can be made into a cultural content. To make a cultural content, storytelling is very important. Therefore, the structure and characteristics of novels of Mongcha group was examined, and a synopsis was made based on this. Furthermore, it examined if there are novels of Mongcha group made into contents, and how each work was vitalized and how much ripple effect it had achieved. If each work did not achieve a second or third ripple effect, it examined what the problem was and tried to offer a solution.

The purposes of this work were to investigate the changes in GABA content of six different rice cultivars along with viatmin E content and antioxidant activity after germination. Brown rice was soaked for 24 hr at 25$^{\circ}C$ and then germinated at 37$^{\circ}C$ for 48 hr. The content of GABA and vitamin E in the rice samples was measured by using spectrophotometeric and HPLC methods, respectively. Antioxidant activity was measured by ABTS (2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid)) and DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging methods. GABA and vitamin E contents were significantly increased after germination while no significant change in the antioxidant activity was observed. Among the samples tested, Geunnun cultivar contained the highest GABA content before and after germination. On the other hand, Sinmyungheugchal cultivar showed the highest content of vitamin E and antioxidant activity compared to other rice cultivars. In conclusion, the germinated rice with high GABA content can be used for a functional ingredient in rice processing industry.
