  • Three kinds of domestic summer grains, barley, naked-barley & wheat were used for the assessment of ash, protein, fat, crude fiber, calcium, iron & thiamine contents in the grain-pearling and flour-milling processes at the 60%, 70%, 80%, 90% yield bases and the following results were obtained. 1) Ash, protein, fat, crude fiber, calcium, iron & thiamine contents of milled grains were proportional to the milling yield in grain-pearling and flour-milling processes. 2) In the case of pearled barley, the average content of ash was 0.83%, protein was 1.31%, fat was 0.40%, crude fiber was 0.75%, calcium was 3.03mg%, iron was 2.40mg% and thiamine was 0.14% lower than the barley flour at the same level of milling yield. 3) In the case of pearled naked-barley, the average content of ash was 0.41%, protein was 1.96%, fat was is 0.33%, crude fiber was 0.84%, calcium was 4.54mg%, iron was 1.19mg% and thiamine was 0.10mg% lower than the naked-barley flour at the same level of milling yield. 4) In the case of pearled wheat, the average content of ash was 0.28%, protein was 2.25%, fat was 0.05%, crude fiber was 0.25%, calcium was 4.31mg%, iron was 0.12mg% and thiamine was 0.15mg% higher than the wheat flour at the same level of milling yield.

  • We studied the green synthesis and antibacterial activity of chitosan-silver (Ag) nanocomposite films for application in food packaging. Green synthesis of Ag nanoparticles (AgNPs) was achieved by a chemical reaction involving a mixture of chitosan-silver nitrate ($AgNO_3$) in an autoclave at 0.1 MPa, $121^{\circ}C$, for 15-120 s. The formation of AgNPs in chitosan was confirmed by both UV-Visible spectrophotometry and transmission electron microscopy (TEM) and the effects of chitosan-$AgNO_3$ concentration and reaction time on the synthesis of AgNPs in chitosan were examined. The resulting chitosan-Ag composite films were characterized by various analytical techniques and their antibacterial activity was evaluated based on the formation of halo zones around films, indicating inhibition of the growth of Escherichia coli. A fourier-transform infrared (FTIR) spectroscopy analysis showed that free amino groups in chitosan acted as effective reductants and AgNP stabilizers. The composite films exhibited enhanced antibacterial activity with increasing Ag content on the surface of as-prepared composite films.

  • 본 논문은 "주역(周易)" 원도(圓道)의 기본원리(基本原理)를 이용하여 임독맥(任督脈)이 순환(循環)하는 원도(圓道)의 특징을 논한 것이다. "건(乾)은 머리가 되고,곤(坤)은 배가 된다"는 것과 "사람 몸의 음양으로 말하면 등은 양(陽)이 되고 배는 음(陰)이 된다."는 규칙에 의하여,임맥(任脈)은 음효(陰爻)에 속하고 독맥(督脈)은 양효(陽爻)에 속한다고 보면 임독(任督) 이맥(二脈)이 건곤(乾坤) 이괘(二卦)와 같으니 십이경맥(十二經脈)의 부모(父母)가 된다고 볼 수 있다. 임독(任督) 이맥(二脈)이 서로 만나는 구조는 순환하고 포괄하며 폐쇄된 원도(圓道)의 형식을 이루고 있다. 위로 향하여 순환하는 것은 이미 임맥(任脈)은 오르고 독맥(督脈)은 내려가는 (정방향의) 영기(營氣)의 순환방식이 존재할 뿐만 아니라 또한 독맥(督脈)은 오르고 임맥(任脈)은 내려가는 (반대방향의) 원기(元氣)의 순환 방식도 존재하므로 정(正)과 반(反)이 서로 혼합(混合)된 태극의 양식을 구성하고 있다. 임독(任督)은 또한 생명(生命)이 기원(起源)하는 기초(基礎)이며 곡기(穀氣) 이도(二道)의 요로(要路)이며 기기(氣機) 승강(升降)의 동력(動力)이며 삼초명문(三焦命門)의 지도리이고, 생리(生理), 병리(病理)와 양생(養生), 치료(治療) 등에 있어서 모두 십이정경(十二正經)의 강령이 된다.

  • The two isolates of Streptomyces antagonistic to Phytophthora nicotianae var. parasitica and Fusarium oxysporum f. sp. vasinfectum were identified as based on the morphological, cultural and physiological characteristics on various culture media. Spore chains of St-11 isolate was rectus-flexibilis(RF), whereas the other isolate, St-20, was shown rectinaculum-apertum(RA). Spore surface of St-11 isolate was smooth, while St-20 was spiny. Aerial mycelia of the two isolates were all gray color and growing conditions on media were good as a whole. Any soluble pigment was not shown in cultivation of the two isolates. Stoll isolate showed negative response on starch hydrolysis and gelation liquefaction, whereas St-20 isolate was positive on starch hydrolysis and a negative on gelatin reaction. Stoll isolate was identified as Streptomyces bikiniensis and St-20 Streptomyces echinoruber, respectively.

  • Purpose: This study was evaluated the shade of feldspathic porcelain with various concentration of silver ion. Materials and Methods: The control group was conventional feldspathic porcelain with no silver ion, the experimental groups were the feldpathic porcelain with 5%, 10%, 20%, 30% silver ion. The number of specimens on the each group was 5. Commission Internationale de I'Eclairage (CIE) $L^*a^*b^*$ parameters were recorded twice for each specimen with a spectrophotometer (Model CM-2600d, Minolta, Japan). One-way Anova was used for statistical analysis. Results: L value was similar. a value was increasing and b value was decreasing with silver ion statistically significantly. ${\Delta}E$ was increasing according to silver ion significantly. Conclusion: The shade of feldspahtic porcelain was influenced by silver ion. Ag ion under 10% concentration is acceptable clinically.

  • 2-Mercaptothiazoline is very sensitive reagent for silver, which have been used for highly selective amperometric determination of silver. A method is described for the determination of micro-quantity of silver by amperometric titration with 2-mercaptothiazoline in ammonical solution. Direct titration of milligram amount of silver (0.05∼1.00mg) is possible in the presence of a number of foreign ions in ammonical solution containing ethylenediaminetetraacetic acid as masking agent under atmosphere. The interfering elements are gold and platinum. The milligram amounts of silver can be determined by the proposed method within an error ${\pm}$5%.

  • 은의 항균작용은 예로부터 알려져 왔는데, 특히 천연섬유에 기생하는 세균(bacteria)과 곰팡이(fungi) 등의 미생물을 제거하여 질병유발, 악취, 제품의 오염 방지에 효과적이다. 은은 다른 가공제와 달리 소량으로 항미생물 효과를 얻을 수 있으므로 나노 사이즈의 은 입자를 농도별로 면직물에 처리하고 세탁에 대한 내구성을 알아보고자 하였다. 이에 따라, 소량으로도 항미생물 효과를 나타내는 최적의 공정을 구하고 은입자가 균일하게 처리되는 조건에서 가공제의 내세탁성을 조사하였다. (중략)

  • 아연-산화은 2차전지는 높은 에너지 밀도의 이점을 가진 반면, 짧은 사이클수명(설계 및 사용방법에 따라 10∼200 사이클)을 가진 단점이 있다. 산화은 전극의 비싼 가격 때문에 높은 에너지 밀도가 요구되는 분야에서 제한적으로 사용되고 있다. 본 논문은 수중운동체계의 추진용으로 사용하기 위한 신뢰성이 높은 아연-산화은 전지의 개발을 다루었다. 고율방전에서 양극 활물질의 양에 따른 전압 특성과 음극활물질의 첨가제에 따른 사이클 수명 비교 시험을 실시하였다. 본 연구결과 우수한 전압 특성과 고율방전에서10회 이상의 사이클 수명을 갖는 아연-산화은 2차전지를 개발하였다.
