  • This paper is mainly on the medical comments in ${\ulcorner}$Sanbeon-bang(刪繁方)${\lrcorner}$. Among the medical comments in ${\ulcorner}Sanbeon-bang{\lrcorner}$, the Ojang-noron(五臟勞論) which deals with the Hanyeolheosil(寒熱虛實) of Ojang(五臟) and Yukgeuknon(六極論) which deals with the Hanyeolheosil of 'Geun-Maek-Yuk-Gi-Gol-Jeong(筋脈肉氣骨精)', remain perfectly. By way of these theories, it argues on various types of pathogenic states and syndromes. Related to the Ojang-noron, ${\ulcorner}Sanbeon-bang{\lrcorner}$ suggests a characteristic tonifying method which is 'Exhaustion syndromes should tonify the son organ(勞則補子法)'. It is the supplement of traditional 'Reinforcing the mother organ when treating cases of deficiency(虛則補其母)'. With the Ojang-noron, the comments about 'Samcho(三焦)' remain relatively intact in ${\ulcorner}Sanbeon-bang{\lrcorner}$. The contents are based on ${\ulcorner}$Yeongchu Yeongwisaenghoe(靈樞 營衛生會)${\lrcorner}$, combined the contents of ${\ulcorner}$Nangyeong 31st difficulty(難經 三十一難)${\lrcorner}$ and the meridian line in ${\ulcorner}$Yeongchu Gyeongmaek(靈樞 經脈)${\lrcorner}$. They were quoted untouched in ${\lrcorner}Cheongeumyo-bang{\lrcorner}$ by Son Sa-mak, and became the fundamental structure of Samcho-theory of after ages. Among the medical comments in ${\ulcorner}Sanbeon-bang{\lrcorner}$, there has been much dispute over the problem about 'Chu-Tae-eum(秋太陰), Dong-So-eum(冬少陰)'. This study will pay attention to the connection between Wang Bing's views of ${\ulcorner}Sanbeon-bang{\lrcorner}$ for compilation of ${\ulcorner}Chaju-Hwangje-Naegyeong-Somun{\lrcorner}$ and the original ${\ulcorner}Sanbeon-bang{\lrcorner}$. Judging from this study, Wang Bing may have referred to ${\ulcorner}Sanbeon-bang{\lrcorner}$, ${\ulcorner}Oedaebiyo-bang{\lrcorner}$ or another medical book of similar stock, and from this he may have reconstructed the attribute of Eum-Yang(陰陽) which is related to Pye and Sin. Wang Bing's disciples may have referred to ${\ulcorner}Sanbeon-bang{\lrcorner}$, or with Wang Do, the writer of ${\ulcorner}Oedaebiyo-bang{\lrcorner}$, building up the main medical current in those days.

  • The purpose of this study was to examine the antimicrobial effects of natural additives on pathogenic microorganisms in commercial chicken during storage. Chicken skin ($20cm^2$) inoculated with Salmonella Typhimurium or Pseudomonas aeruginosa was treated with 2% natural additives, including chitosan, epigallocatechin gallate (EGCG) and garlic, during storage at $4^{\circ}C$ for 12 days. A combination of the three natural additives significantly inhibited growth of S. Typhimurium compared to treatment with chitosan, EGCG or garlic alone (p<0.05). This combination also inhibited growth of P. aeruginosa compared to treatment with one or two of the natural additives (p<0.05). These results suggest that combined chitosan, EGCG, and garlic may be used as an antimicrobial agent in commercial chicken during refrigerated storage.

  • Soil salinization refers to the buildup of salts in soil to a level toxic to plants. The major factors that contribute to soil salinity are the quality, the amount and the type of irrigation water used. The presented review discusses the different sources and causes of soil salinity. The effect of soil salinity on biological processes of plants is also discussed in detail. This is followed by a debate on the influence of salt on the nutrient uptake and growth of plants. Salinity decreases the soil osmotic potential and hinders water uptake by the plants. Soil salinity affects the plants K uptake, which plays a critical role in plant metabolism due to the high concentration of soluble sodium ($Na^+$) ions. Visual symptoms that appear in the plants as a result of salinity include stunted plant growth, marginal leaf necrosis and fruit distortions. Different strategies to ameliorate salt stress globally include breeding of salt tolerant cultivars, irrigation to leach excessive salt to improve soil physical and chemical properties. As part of an ecofriendly means to alleviate salt stress and an increasing considerable attention on this area, the review then focuses on the different plant growth promoting bacteria (PGPB) mediated mechanisms with a special emphasis on ACC deaminase producing bacteria. The various strategies adopted by PGPB to alleviate various stresses in plants include the production of different osmolytes, stress related phytohormones and production of molecules related to stress signaling such as bacterial 1-aminocyclopropane-1-carboxylate (ACC) derivatives. The use of PGPB with ACC deaminase producing trait could be effective in promoting plant growth in agricultural areas affected by different stresses including salt stress. Finally, the review ends with a discussion on the various PGPB activities and the potentiality of facultative halophilic/halotolerant PGPB in alleviating salt stress.

  • This experiment was conducted to investigate planting depth, which applied the basic data for planting growth ability and mechanical planting of oriental melon. 'Gumssaragi-eunchun' variety was approach grafting to 'Shintozoa' and seedling was growing during 45 days in the 9cm pot and then planted on Jan. 16. The comparison of planting plots was carried out for four experimental plots, which were separated into 0cm, 4.5cm, 9cm, standard cultivation, and 12cm planting depth in soil. In the tunnel of vinyl house, the lowest and the highest temperature was $9.3^{\circ}C\;and\;41.2^{\circ}C$, respectively, and humidity was $59\~99\%$ during Jan. 18 and 19. The faster graft-take rate after planting was the deeper planting depth. The growth of 40 days after planting was not significant in each planting plot, except 0cm experimental plot. Fruit weight was the heaviest in 4.5cm planting depth of experimental plot but sugar content and flesh thickness were not significant in each planting depth. The more depth in planting meant the more increase in fermented fruit rate and decrease in marketable fruit rate. Marketable yield was 2,361kg per l0a in 9cm planting plot, which was $2\%\;and\;1\%$ lower than in 0cm and 4.5cm, respectively, and $11\%$ greater than in 12cm planting plot.

  • This study was conducted to investigate the effect of grafting methods on plug seedling quality, growth after transplanting, and yield of oriental melon that those seedlings were raised in the 32 hole plug tray for protected cultivation. Number of leaf and leaf area in approach grafting were higher until 15 days after grafting but lower on 20 days after grafting. Plant height, stem diameter and content of chlorophyll were nearly the same of each grafting methods on 20 days after grafting. Growth of top part, that is, plant height, leaf number, and leaf area on root removed single cotyledon ordinary splice grafting was the highest among the grafting methods. In the underground part, dry weight of root was high and T/R ratio was the lowest. Seedling quality of root removed single cotyledon ordinary splice grafting was the highest among grafting methods before transplanting. Plant height, number of leaf, leaf area and dry weight of root removed single cotyledon ordinary splice grafting in the growth of field were the highest on 30 days after grafting among grafting methods and days required for first flowering was also shorter, 38.4 days among grafting methods. But Fruit weight, content of soluble solids, fruit hardness, and color characteristics in fruit quality were insignificant among each grafting methods. Consequently, grafting methods influenced on the seedling quality, of oriental melon early growth after transplanting and yields. It was concluded that root removed single cotyledon ordinary splice grafting was the best methods in present study. It will be needed to convert grafting methods. Thus new grafting method should be applied.

  • This experiment was carried out to investigate the influence of flooding on the quality and yield of an oriental melon. Waterlogging for four periods, 0(not flooded), 5, 10 or 15h, were applied to 30cm depth from the soil surface. The soluble solids content of fruit flesh measured at 7 days after waterlogging was 12.6 Brix in not-flooded plot, but it decreased by 4.7-5.6 Brix in plots flooded 5, 10 or 15h, respectively. Difference in fruit hardness between the no-flooded and 5h-flooded plots was not observed, while a significant decrease in fruit hardness was observed in 10 or 15 h-flooded plots at 7 days after waterlogging. Decrease in fruit hardness in all plots except control plot was observed at 13 days after waterlogging. The percent decayed fruits at 7 days after waterlogging was not observed, but at 13 days after waterlogging it gradually increased as duration of flooding increased. The incidence of downy or powdery mildews increased is significantly in plots flooded for 5, 10 or 15h as compared to the not-flooded control. However, population of cotton caterpillar decreased in the flooded plots. Marketable fruits yield per 10a was 616.2kg in no-flooded plot, but it decreased by 33%, 45% and 66%, respectively, in plots flooded for 5, 10 or 15h. The waterlogging during fruit enlargement stage significantly deteriorated fruit quality and decreased marketable fruit yield.

  • The experiment was conducted to investigate the effect of different mulching materials on the growth and quality of oriental melon in protected cultivation. Soil temperature, plant growth and fruit quality were affected by different mulching materials, clear polyethylene (P.E.) film (control), clear inset between black P.E. film, green P.E. film. and recycled ethylene vinyl acetate (E.V.A.) film. The highest night soil temperature was at 20 cm depth under green P.E. film, but was at 5 cm depth under other materials. Difference of soil temperature as affected by mulching materials decreased with increasing soil depth. Plant height, number of nodes, leaf area index (LAI), crop growth rate (CGR), and relative growth rate (RGR) at 30 days after transplanting were significantly greater in the recycled E.V.A. film treatment than in the other treatments. Fresh weight of weeds growth under the mulching materials was not affected by mulching material at 30 days after transplanting. However, it was the greatest under clear P.E. film mulching at 90 days after transplanting. Harvesting time of recycled E.V.A. film was 2 days earlier than that of clear P.E. film. Difference in fruit weight and length, and soluble solid content were not affected by the mulching materials. Marketable yield was 2,426 kg.10a$^{-1}$ in recycled E.V.A. film treatment, which was 6% greater than in clear P.E. film treatment.
