본 연구는 새로운 항 vancomycin 내성균성 항생물질을 개발하기 위하여 실시되었으며, 전국 각지의 토양 시료로부터 분리한 방선균 중 vancomycin 내성균주인 K-98 Enterococcus faecium 642, K-98 Enterococcus faecium 637 균주에 대하여 항생물질을 생산하는 분리균주 AMLK-335를 선정하여 이 균주의 항생물질 생산에 대한 최적 발효 조건을 검토한 결과, 탄소원 첨가로는 glycerol(0.5%), 질소원 첨가로는 yeast extract(0.5%)가 가장 효과적으로 항생물질 생산에 이용되었고, 비타민을 첨가에 따른 항생물질 생산성의 차이는 크게 나타나지 않았으나, calcium pantothenate 첨가시 항균활성이 비교적 높아졌으며, 금속이온의 첨가는 K+, Pb+, Ba²+, NA²+ , Ca²+를 첨가하였을 때는 항생물질의 생산성이 비교적 높아졌으며, 그중 Ca²+ 첨가구가 가장 생산성이 높았으며, Fe²+ , Hg+의 금속이온을 첨가하였을 때는 항생물질 생산성이 감소하였으며, CaCO₃첨가는 비첨가구보다 높은 항생물질 생산성을 보였으나, 첨가량에 따른 영향은 대체적으로 없었다. pH의 변화에 따른 생산성은 전반적으로 pH가 항생 물질 생산에 영향을 미치지 못하였으나, pH 4.5∼6.0 부근에서는 비교적 높은 항생물질 생산성을보였으며, 통기량에 따른 항생물질 생산성은 통기량이 많을수록 항생물질 생산이 좋았다. 한편 배양기간에 따라 항생물질 생산성을 조사한 결과, 5일째에 가장 높은 항생물질 생산성을 나타내었으며, pH의 변화는 배양 초기에 하강하였다가 점차 상승하는 경향을 보였다. This study was carried out for examining antibiotic productivity of the strain Streptomyces sp. AMLK-335 producing anti-VRE antibiotic. According to different condition, the strain was cultured for 4 days at 27℃ and determined cell growth, pH value and antibiotic productivity using disk diffusion method. In the experiment, the strain Streptomyces sp. AMLK-335 was examined various culture conditions which was added 8 carbon sources, 12 nitrogen sources, 8 vitamins and 11 metal ions in each time and controlled concentration of CaCO₃, initial pH and aeration. From the studies of conditions for antibiotic production, antibiotic productivity was the best to use 0.5% glycerol as carbon source and 0.5% yeast extract as nitrogen source. When several vitamins were added to medium, there was little difference in antibiotic productivity. But the addition of calcium pantothenate slightly increased antimicrobial activity. The addition of metal ion, such as K+, Pb+, Ba²+, NA²+ and Ca²+ slightly increased antibiotic productivity except Fe²+ and Hg+. The addition of CaCo₃showed higher than non-addition experiment in antibiotic production, but there wasn't generally influenced at addition concentration. According to pH change, antibiotic productivity was increased at pH 4.5∼6.0, and when there was a lot of aeration, antibiotic productivity was increased.

Dental composite resin is filler added, particle reinforced composite material, and the usage range had been enlarged in the posterior restoration through improvement of physical properties. Recently, resin modified glassionomer and compomer are used for various purposes. The degree of polymerization of cross-liked polymer has great importance in determining the mechanical properties and clinical availability of materials. Residual carbon-carbon double bonds have been implicated in causing reduced wear resistance, strength and color stability. The degree of polymerization is an important factor for longevity of a restoration. However the higher the degree of polymerization in resin composites, the higher the shrinkage will result. It has been elucidated that the degree of polymerization was significantly affected by the intensity of the curing light, wavelength of light and irradiation time. In this experiment, 16 kinds of restorative materials such as five kinds of universal composite resin, five kinds of condensable composite resin, two kinds of flowable composite resin, and four kinds of compomer were used. This study examined the effect of light intensity and irradiation time on the polymerization behavior such as the heat release during polymerization and the rate of polymerization by DSC (differential scanning calorimeter), and the degree of double bond conversion by FT-IR. With DSC, the irradiation modes were three different light intensity of 300, 400, 600 ㎽/㎠ and for 40 seconds. With FT-IR, the levels of irradiation energy were 1,500, 40,000, 8,000, 16,000 and 24,000 mJ/㎠ by combining the light intensity of 300, 400, 600 ㎽/㎠ and irradiation time of 5, 10, 20 and 40 seconds. From this experiment, The following results were obtained : 1.In the DSC result, heat of polymerization of composite resin was 23.22∼55.17J/gram and exothermic energy of compomer was 26.50∼52.68 J/gram 2.At the isothermal condition of 27℃, there were exothermal peaks at 40.812∼44.724 seconds from the start of irradiation. The percentage of polymerization by released heat was 19.12∼49.44% after 18 seconds, 37.23∼82.07% after 36 seconds, and 93.57∼98.53% after 54 seconds from the start of irradiation. 3.From FT-IR, the degree of polymerization of composite resin was 17.17∼60.91% and that of compomer was 7.74∼40.82%, and the degree of final conversion was influenced by the kinds of restorative materials and the irradiation energy(p<0.01). 4.As the irradiation energy was increased from 1,500 mJ/㎠ to 16,000 mJ/㎠, the degree of conversion was increased also. However, the degree of final conversion was no significant differences with the irradiation energy of 24,000 mJ/㎠ and 16,000 mJ/㎠(p>0.05). The wavenumber of absorbance peak of aromatic double bond was similar regardless of the restorative materials, and appeared around 1606.67∼1610.67 cm-1. The absorbance peak of aliphatic double bond appeared around 1636.64∼1638.52 cm-1 from FT-IR.

This studies were conducted to investigate the effects of rain shelter and netting on the tree growth, fruit set fruit quality of kiwifruit (Actinidia deliciosa). In rain shelter and net house, shoot falling wasn't occurred by strong wind, and fruit set, fruit weight and also fruit malformation, side flowering increased at the same time. In rain shelter house the increment temperature forced blooming date and increased shoot length, leaf number and diameter but in net house these tendencies were not observed. Relative light intensity of rain shelter house was higher than that of net house with standard of field culture (relative light intensity: 100%). Soluble solid content was higher in rain shelter house, and acid content was higher in net house. With the effect of rain sheltering the occurrence of bacterial bloom rot and canker significantly decreased in both rain shelter and net house but insect injury increased. These data showed that rain shelter house is more suitable for kiwi fruit culture.

( Kyeong-ha Shin ),( Byeong-jun Park ),( Jeong-eun Lim ),( Sam-haeng Lee ),( Myung-gyu Lee ),( Joo-seok Park ),( Sung-gap Lee ) 한국전기전자재료학회 2022 전기전자재료학회논문지 Vol.35 No.3

(La_0.5Nd_0.2Sr_0.3)MnO₃ specimens were prepared by a solid-state reaction. In all specimens, X-ray diffraction patterns of an orthorhombic structure were shown. The fracture surfaces of (La_0.5Nd_0.2Sr_0.3)MnO₃ specimens showed a transgranular fracture pattern be possibly due to La ions (0.122 nm) as a perovskite A-site dopant substituting for Nd ions (0.115 nm) having a small ionic radius. The full-width at half maximum (FWHM) of the Mn 2p XPS spectra showed a value greater than that [8] of the single valence state, which is believed to be due to the overlapping of Mn²⁺, Mn³⁺, and Mn⁴⁺ ions. The dependence of Mn 2p spectra on the Mn³⁺/Mn⁴⁺ ratio according to sintering time was not observed. Electrical resistivity resulted in the minimum value of 100.7 Ω-cm for the specimen sintered for 9 hours. All specimens show a typical negative temperature coefficient of resistance (NTCR) characteristics. In the 9-hour sintered specimen, TCR, activation energy, and B25/65-value were -1.24%/℃, 0.19 eV, and 2,445 K, respectively.

Lee, Youn-Sun,Choi, Kyeong-Mi,Lee, Seunghyun,Sin, Dong-Mi,Lim, Yong,Lee, Yong-Moon,Hong, Jin-Tae,Yun, Yeo-Pyo,Yoo, Hwan-Soo Landes Bioscience 2012 Cancer biology & therapy Vol.13 No.2

<P>Advanced melanoma is the most virulent form of cancer and has a poor prognosis. In a previous study, myriocin, an inhibitor of serine palmitoyltransferase, was found to suppress melanoma cell proliferation by cell cycle arrest at the G 2/M phase through decreased sphingolipid levels and increased p53 and p21 (waf1/cip1) expression. ( 1) In the present study, myriocin (1 mg/kg, every other day for 3 weeks) was administered intradermally or intraperitoneally to melanoma mice. Tumor formation was significantly inhibited by intradermal and intraperitoneal administration of myriocin. The expression of Cdc25C, Cdc2 and cyclin B1 was decreased in tumor tissues from myriocin-treated mice, while the expression of p53 and p21 (waf1/cip1) was increased compared with that of the controls. The levels of sphingolipids in serum, liver and tumor tissue from myriocin-treated mice were decreased compared with those of controls. The decreased levels of sphingolipids in serum and liver of melanoma mice treated with myriocin suggests that myriocin may be accessible to tumor tissues of advanced melanoma. Taken together, the suppression of sphingolipid synthesis by myriocin inhibits the expression of Cdc25C or activates the expression of p53 and p21 (waf1/cip1) . This is followed by Cdc2 and cyclin B1 inhibition which results in the suppression of tumor growth.</P>
