This paper suggested a cyber collaboration platform based on web for food safety service. We implemented the cyber collaboration platform for food safety service so that the users participated in collaborative work may refer shared media objects as the same view to others. In this paper, we discussed a model for increasing reliability of food safety data through N screen server and client model. This paper explained a performance analysis of a system with function comparison running on multimedia collaboration work based on web and N screen techniques.

The aim of this study was to provide basic data for breeding new varieties of Angelica gigas Nakai by identifying the growth characteristics and useful components of its below- and above-ground parts. The basic varieties expressing dark purple (N79-A), light blue-pink (62-C), and white (NN115-C) flowers were identified and collected in the cultivation area, and their seeds were cultured for use as experimental materials. Qualitative growth characteristics of the above-ground parts were then examined. Purple coloration was evident throughout the entire plant body in the N79-A group, whereas the 62-C and NN115-C groups displayed yellow-green coloration. In terms of quantitative growth characteristics, the 62-C group displayed significantly lower above- and below-ground growth than the other two groups. Levels of nodakenin and decursinol-angelate were high in the NN115-C group (0.88 ± 0.13%) and N79-A group (2.56 ± 0.12%). However, the overall results were not statistically significant. The results could provide a foundation for breeding new varieties of Angelica gigas Nakai, which are used predominantly for medicinal purposes and have low bolting and high yield potential.

The crystal structure of 1-tert-butoxycarbonyl-4-[N-(tert-butoxycarbonyl)-N-(ethoxycarbonylmethyl)amino]-3-phenylsulfonylpyrrolidind [C24H36O8N2S] has been from single crystal x-ray diffraction study ; C24H36O8N2S triclinic, p1, a=11.363(8)Å, b=11.589(6)Å, c=11.013(10)Å,α=95.32(6)°,β=98.64(7)°,γ=79.57(5)°,V=1406.8(18)Å3, t=293K, Z=2, CuKα(λ=1.5418Å). The molecular structure was solved by diredt method and refined by full-matrix least squares to a final R=9.78% for 3621 unique observed [F≥4σ(F)] reflections and 703 paramenters.

고려인삼은 아시아 지역에서 수세기동안 강장제 및 치료약으로 광범위하게 사용되어 왔으며, 안전성 및 치료약으로서의 가치는 고대 한의서에 잘 명기되어있다. 그러나 근래에 들어서 인삼의 복용이 전세계로 확산됨에 따라 안전성 및 인삼의 약리작용에 대한 정확한 기전이 흥미를 끌게 되었다. 따라서 저자는 Salmonella typhimurium tester strain TA 100과 TA 98 및 V-79 Chinese hamster cell line을 이용하여 고려인삼의 안전성을 확인하기 위하여 본 연구를 수행하였다. 지금가지의 결과는 고려인삼이 안전하다는 것을 시사한다.

This study was conducted to investigate tissue nutrient contents and salt accumulation in plastic house soils cultivating lily, rose and carnation. The soil tested had high total salts, available phosphate and exchangeable potassium. The soil cultivating rose had highest salt concentvation followed by chose of carnation and lily. Tissue nutrient contents of lily were higher than chose of carnation and rose. In comparison among cultivars, the nutrient contents were as follows; 'Snow Qeen'>'Le Reve'>'Casa Blanca' in lily; 'Marina'>'Super star'>'Mary Devor'>'Madelon' in carnation; and 'Cocktail'> 'Marina'>'Maderon' in rose. The range of the nutrient contents were: T-N: $1.66\;{\sim}2.35%$, K: $1.73{\sim}2.23%$, Zn: $2.13{\sim}6.43\;mg/kg$, Cu: $3.79{\sim}13.89\;mg/kg$ in carnation; T-N: $0.79{\sim}1.65%$, P: $0.18{\sim}0.44%$, Ca: $0.59{\sim}1.26%$, Mg: $0.21{\sim}0.46%$, Zn: $23.65{\sim}90.30\;mg/kg$, Cu: $0.99{\sim}4.62\;mg/kg$ in lily; and T-N: $0.75{\sim}1.62%$, P: $0.17{\sim}0.30%$, K: $1.60{\sim}2.91%$, Ca: $0.64{\sim}0.94%$, Zn: $24.57{\sim}48.31\;mg/kg$, Cu: $3.10{\sim}9.08\;mg/kg$ in rose. The amount of nutrients uptake per plant was high in order of: K > T-N > Ca > Mg in lily; and T-N > K > Ca > P > Mg in rose.

Two pathogen-induced hot pepper transcription factors (CaNACl and CapIfl) were introduced into‘MicroTom’tomato by Agrobacterium tumefaciens-mediated transformation. We used to nptII containing kanamycin resistance gene as a selection marker. Both transformed and non-transformed plants were transferred to pot after rooting test in vitro. To approximate the levels of caNACl transcript in leaves of wild-type and transgenic plants, RNA blots were hybridized with double-stranded full-length CaNACl probe at moderate stringency, Although the relative signal strength for hybridization fluctuated among the samples on different blots, transgenic plant lines N-1, N-2 and N-3 consistently displayed increased levels of CaNACl transcript relative to other transgenic lines and wild-type plants. Of all the transgenic lines examined, line N-7 had the least amount of CaNACl transcript. Role of these transcription factors in pathogen defense will be examined by overexpression in tomato.
