Background: The purpose of improving the quality of oriental medicinal herbs is to contribute to the improvement of the income of farm. The present study investigated the effect of reasonable drying methods, different storage conditions and packageing materials on quality and stability of Scutellaria baicalensis Georgi and for developing GAP (good agricultural practice) guide book. Methods and Results: Three methods of drying Scutellaria baicalensis roots produced over two years were used to estimate loss rate owing to drying, storage, and packaging. The methods of drying were categorized into natural drying (36 - 60 h by sunshine), drying with heat dryer (2 - 10 h), or drying with gas bulk dryer (2 - 10 h). After cleaning, and initial drying for a few days under controlled temperature conditions, the second phase of drying was carried out at 35, 45 and $55^{\circ}C$. Changes in hunter color values and quality under the two studied storage treatments (at $20^{\circ}C$ indoors and at $4^{\circ}C$ in a refigerator) were evaluated. Storage period for 60, 120, and 180 days in three packaging materials, PE (polyethylene package), PP (polypropylene gunnysack), and WP (watertight packing paper) were studied. Conclusions: Initial cleaning, reasonable gas drying and hot air drying, and drying in an oven at 35 and $45^{\circ}C$ after cutting the roots resulted in the lowest loss rates in S. Baicalensis root. Hunter color valuse indicated that stroage of dry roots at room temperature was better than PP packaging, and that cold stroage was better than PE packaging for long-term stability.

An outbreak of Ricania sp. occurred in the Kurye, Jeonnam area in 2011. This outbreak damaged many kinds of fruit trees such as Cornus, Persimmon and Chestnut. This experiment was conducted to survey the occurrence ecology of Ricania sp. such as host plants, oviposition characters, morphological characters and life cycle, as well as to select environmental friendly control agents. Ricaina sp. host plants included 51 species such as 32 xylophytes, and 19 herbaceous plants. Ricaina sp. preferred Cornus officinalis, Diospyros kaki, Castanea crenata, Eucommia ulmoides, Styrax japonicus for oviposition. Adults laid eggs on new inner twigs with 28.8 eggs per egg-mass. Egg size was 1.24 mm(length), 0.55 mm(width) in an oval shape. Nymphs molted four times. Every nymph stage had an x shape of yellow or white beeswax around the anus. Overwintered eggs of Ricania sp. hatched from the mid May to early June. Nymphal periods were from mid May to mid August and adults appeared from mid July but spawning began in mid August. Ricania sp. damaged new twigs by oviposition and retarded growth by sucking nutrients and producing a sooty mold. Sophora and natural plant extracts were effective environmentally friendly agricultural materials used to control the nymph and adult Ricania sp. Mortality was > 80%.

In general, Reucedani Radix (Peucedanum japonicum Thunbergis: PJ) is the Korean traditional herbal medicine used to remove dampness, to relieve pain, and spasm. So, PJ folium is believed to have the same effects. The aim of this study is to investigate the alleviation of dextran sulfate sodium (DSS) induced ulcerative colitis in mice by PJ folium. 25 mice were divided into 5 groups: normal, DSS, DSS + 100 mg/kg PJ folium (PJ100), DSS + 500 mg/kg PJ folium (PJ500), and DSS + 150 mg/kg 5-amino salicylic acid (5-ASA) groups. Body weights, colon lengths, histological changes in colon tissue, and spleen weights were observed. Inflammatory cytokines such as IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ level in plasma were measured by ELISA. IL-$1{\beta}$, IL-6, and TNF-a mRNA expression in colon tissue were detected by RT-PCR. In the results, body weight lose was inhibited in PJ100, PJ500, and 5-ASA groups, but it was not different compared with DSS group, significantly. PJ500 group showed the preventive effects of colon length shorten and histological changes in colon tissues as good as 5-ASA group. The weight of spleen was increased in DSS group but it reduced in PJ100, PJ500, and 5-ASA groups. Moreover, IL-$1{\beta}$ and TNF-${\alpha}$ cytokine levels in plasma were reduced in PJ500 and 5-ASA groups. IL-$1{\beta}$, IL-6, and TNF-a mRNA expression in colon tissue were inhibited in PJ100, PJ500, and 5-ASA groups and it was significantly different compared with DSS group. In conclusion, PJ folium showed the alleviative effect on DSS induced ulcerative colitis in mice.

The study was carried out to examine the anti-obesity effects of 40% ethanol extract from green tea seed (GS) and quantitative determination of caffeine as its major compound. The specificity was satisfied with retention time and UV spectrum by analysis of caffeine using HPLC and comparison with standard compound. It showed a high linearity in the calibration curve with a coefficient of correlation (R²) of 0.9974. The amount of caffeine in GS was about 4.649 mg/g (0.465%) in the three times analysis, and relative standard deviation (RSD) was less than 0.452% by the validated method. The anti-obesity effects of GS were evaluated by using Oil Red O staining in 3T3-L1 adipocytes and body weight, visceral fat and lipid profiles in high fat diet (HFD)-induced C57BL/6 obese mice. Our results indicated that treatment with GS dose-dependently decreased lipid accumulation contents (p<0.001). Moreover, after oral administration for 30 days feeding with HFD-induced obses mice, GS (100 and 300 mg/kg/day) produced a significant decrease in serum total cholesterol (TC), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) and visceral fat. Thus, the result of this study indicate that the GS may be a useful resource for the management of obesity.

This study aimed at setting up the grading indicator standards on development stages for phasing the continuous development process. To achieve the objective of this study, after referring to the proposed cases derived from the reference analysis, the development stages were classified. Also grading criteria of indicators according to development stages were established through the statistical analysis and expert group checking. Development stages of rural village were stepped into 4-stages through the reviews and analysis of reference literature ; preparation-entry-development-advanced stage. Reasonable achievement level of each development stage was established by considering the necessary development period and benchmarking reference target together. On the basis of these clear stepwise development phases, the grading criteria were proposed for determination of the incumbent development stages.
