The study attempted to document the concept of farm tourism by categories and to evaluate the farm tourism projects developed in Kyungpook area, and also to formulate a device for improving such projects in Kyungpook area. For these purposes we have examined the existing patterns of farm tourism projects developed in Kyungpook area since 1986 and evaluated such projects conducted in same area. We also attempted to find out what were the problems conducting such projects. To estimate the demand patterns of farm tourism we have done a survey conducted in city and urban areas and documented consumer's preferences which patterns were willing to. Finally we suggested, in this study, several strategies for improving the farm toruism projects in Kyungpook area.

Synthetic amethyst grown from hydrothermal method and subsequently irradiated with gamma ray was investigated by polarizing microscopy, emission spectroscopy, atomic absorption spectroscopy, X-ray diffraction electron microscopy, infrared absorption spectroscopy, heating and freezing microscopy, density balance, and optical refractometry. Natural amethysts collected from Sokrisan, Eonyang, and Brazil were also studied to compare their mineralogical and gemmological properties with those of the synthetic counterpart. Synthetic and natural amethysts show exactly or nearly identical properties in specific gravity, refractive index, crystal structure, and chemical composition. In contrast, UV-visible spectrometry and I. R. spectrometry data, solid and fluid inclusion features, and color distribution differ considerably which may be used in differentiating the synthetic from its natural equivalents.

A statistical analysis for 3651 genetic resources collected from China (1,542), Japan (1,409), Korea (413), and India (287) was conducted using normal distribution, variability index value (VIV), analysis of variation (ANOVA) and Ducan’s multiple range test (DMRT) based on a data obtained from NIRS analysis. In normal distribution, the average protein content was 8.0%, whereas waxy type amylose and common rice amylose were found to be 8.7% and 22.7%, respectively. The protein contents ranged from 5.4 to 10.6% at the level of 95%. The waxy amylose and common rice amylose ranged from 5.9 to 11.5%, and from 16.9 to 28.5% at 95% confidence level, respectively. The VIV was 0.59 for protein, 0.64 for low amylose, and 0.81 for high amylose contents. The average amylose contents were 18.85% in Japanese, 19.99% in Korean, 20.27% in Chinese, and 25.46% in Indian resources, while the average protein contents were found to be 7.23% in Korean, 7.73% in Japanese, 8.01% in Chinese, and 8.17% in Indian resources. The ANOVA of amylose and protein content showed significant differences at the level of 0.01. The F-test for amylose content was 158.34, and for protein content 53.95 compared to critical value 3.78. The DMRT of amylose and protein content showed significant difference (p<0.01) between resources of different countries. Japanese resources had the lowest level of amylose contents, whereas, the lowest level of protein content was found in Korean resources compared to other origins. Indian resources showed the highest level of amylose and protein contents. It is recommended these results should be helpful to future breeding experiments.

Background: Atractylodes radix is a well-known medicinal crop having many physiological effects. This study was conducted to select useful Atractylodes japonica × Atractylodes macrocephala (AJM) cultivars by comparing anti-oxidative and anti-inflammatory efficacies. Methods and Results: Seven extracts from AJM cultivars were used to treat lipopolysacchride (LPS)-treated BV2 cells, and the effects on cell viability and inhibition on reactive oxygen species (ROS) and nitric oxide (NO) production were analyzed. In vitro scavenging activities of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and peroxynitrite (NOO−) radicals were also investigated. Contents of total phenol, atractylenolide I, and atractylenolide III in the AJM extracts were measured using high performance liquid chromatography (HPLC) or spectrophotometry. The experiments show that none of the seven extracts was cytotoxic above 89.2% at 20 - 250㎍/㎖. Extracts of Gowon, Dawon, Sangchul, and Huchul inhibited ROS generation in a dose-dependent manner, and Sangchul extract showed the highest inhibition on ROS production. All the AJM extracts showed effective inhibitory activity after on NO release in the LPS-treated BV2 cells, and Sangchul extract showed the highest activity. Sangchul extract had the most potent scavenging activities for NOO− and had some DPPH radical scavenging effect. Sangchul extract also had the highest content at total phenol and atractylenolide I content. Atractylenolide III was not detected in the AJM extracts. Conclusions: The results suggested that Sangchul was the most useful anti-oxidative and anti-inflammatory resource among the AJM cultivars.

Background : Panax ginseng the king of Oriental medicines, has enormous potential against many of the disease symptoms and ailments. Panax quinquefolius is an another important member of Panax family which has similar benefits and medicinal properties. Both the species contains ginsenosides a pharmacologically active component abundant in their roots. In an effort to establish the new ginseng cultivars with improved agronomical characters such as root shape, stress tolerant and higher ginsenoside contents, the reciprocal interspecific hybrids were generated Methods and Results : Four elite cultivars and two new lines of ginseng were chosen to produce interspecies reciprocal hybrids with P. quinquefolius, by pollen dusting on the emasculated flowers. Among the F1 populations, the reciprocal hybrids generated by using new line 0837 both as maternal and paternal parent showed better properties and hybrid vigor. They showed strong root phenotypes with many lateral and fine roots thus having 10% to 20% higher ginsenoside contents compared to the parental populations. Among the major ginsenosides, the pharmacologically active ginsenosides such as Re, Rb1, Rb2 and F1 were enriched and accounted for the 70% of the PPD ginsenosides in 0837/Pq and Pq/0837 crosses, displaying strong dominance. Conclusion : Thus, based on our result we could conclude that P. ginseng line 0837 is the superior variety compared to the already existing lines for performing the interspecific hybrids with promising outcome in their root quality and ginsenoside content.
