<P>We designed and fabricated a gold (Au)-coated nanowires/graphene (Au-SiNWs/G) hybrid composite as a polymer binder free anode for rechargeable lithium ion batteries (LIBs). A large amount of SiNWs for LIB anode materials can be prepared by metal assisted chemical etching (MaCE) process. The Au-SiNVVs/G composite film on current collector was obtained by vacuum filtration using an anodic aluminum oxide (AAO) membrane and hot pressing method. Our experimental results show that the Au-SiNVVs/G composite has a stable reversible capacity of about 1520 mA h/g which was maintained for 20 cycles. The Au-SiNWs/G composite anode showed much better cycling performance than SiNWs/ polyvinylidene fluoride (PVDE)/Super-P, SiNWs/G composite, and pure SiNWs anodes. The improved electrochemical properties of the Au-SiNWs/G composite anode material is mainly ascribed to the composite's porous network structure.,(C) 2014 Elsevier B.V. All rights reserved.</P>

Purposes :The purposes of this study was to investigate the self-managing status according to the life styles and the diabetic knowledge of early adulthood. The subjects in this study were 240people, the early adult aged twenties to thirties living in the metropolitan area. Data were collected by using self-administered questionnaires that measure about the knowledge of diabetes; the dietetic behavior; the knowledge of diet; the exercise behavior; the knowledge of exercise. Descriptive statistics, t-test, ANOVA, and correlation were used for data analysis. Result :1. At the knowledge of diabetes degree based on the general character, the subjects who had experiences of diabetic education have higher degree of the diabetic knowledge. 2. At the knowledge of diabetes degree according to the life style, the subjects who have regular diet are appeared highly. Also the subjects who don't take much food of animal origin have higher degree. 3. At the knowledge of diet based on the life style, the subjects who don't keep three times meals a day are appeared highly. Also the subjects who have regular diet have higher degree. 4. At the knowledge of exercise according to the life style, the subjects who take extra nutritions 3-4 times a week are appeared highly. Although the subjects tend to know about dietary, exercise and health management, it showed that they actually don't perform what they know in their everyday of life. The reason for this could be the lack of perceived seriousness about diabetes mellitus. Thus as nursing professionals, we should provide them proper health education and support. Moreover, advanced research on the empowerment is warranted.

Four three-dimensional Zn<SUP>II</SUP> frameworks containing malonates and various bipyridyl pillars (4,4'-bipyridine (1), 1,2-bis(4-pyridyl)ethane (2), 1,2-bis(4-pyridyl)ethylene (3) and 1,3-bis(4-pyridyl)propane (4)) have been prepared, and their structures were determined by X-ray crystallography. In all four frameworks, malonate ligands bridge three Zn ions to form two-dimensional layers, and these layers are connected by bipyridyl pillars to form three-dimensional frameworks with the general formula [{Zn(H<SUB>2</SUB>O)(μ-malonate)}<SUB>2</SUB>(μ-bipyridyl)] and which also contain water or acetonitrile solvates. Reactivity studies of compounds 1-4 showed that they catalyzed a heterogeneous transesterification reaction of phenyl acetate and could be reused without any significant loss of activity through five runs. Emissions were observed at 347-365nm (λ<SUB>ex</SUB>=313nm) for 2 and 363nm (λ<SUB>ex</SUB>=328nm) for 3, while compounds 1 and 4 showed no luminescence properties. The thermal stabilities of these complexes were also examined.

Exposure of the skin to ultraviolet B (UVB) radiation leads to epidermal damage and the generation of reactive oxygen species (ROS) in skin cells, including keratinocytes. Therefore, the photo-protective effect of 3-bromo-4, 5-dihydroxybenzaldehyde (BDB) against UVB was assessed in human HaCaT keratinocytes exposed to UVB radiation in vitro. BDB restored cell viability, which decreased upon exposure to UVB radiation. BDB exhibited scavenging activity against 1, 1-diphenyl-2-picrylhydrazyl radicals, intracellular ROS induced by hydrogen peroxide (H<SUB>2</SUB>O<SUB>2</SUB>) or UVB radiation, the superoxide anion generated by the xanthine/xanthine oxidase system, and the hydroxyl radical generated by the Fenton reaction (FeSO<SUB>4</SUB>+H<SUB>2</SUB>O<SUB>2</SUB>). Moreover, BDB absorbed UVB and decreased injury resulting from UVB-induced oxidative stress to lipids, proteins and DNA. Finally, BDB reduced UVB-induced apoptosis, as exemplified by fewer apoptotic bodies and a reduction in DNA fragmentation. Taken together, these results suggest that BDB protects human keratinocytes against UVB-induced oxidative stress by scavenging ROS and absorbing UVB rays, thereby reducing injury to cellular components.

Hyun, H.,Henary, M.,Gao, T.,Narayana, L.,Owens, E. A.,Lee, J. H.,Park, G.,Wada, H.,Ashitate, Y.,Frangioni, J. V. Elsevier Science B.V., Amsterdam. 2016 Molecular imaging and biology Vol.18 No.1
<P>Purpose: The purpose of this study was to develop a family of 700-nm zwitterionic pentamethine indocyanine near-infrared fluorophores that would permit dual-channel image-guided surgery. Procedures: Three complementary synthetic schemes were used to produce novel zwitterionic chemical structures. Physicochemical, optical, biodistribution, and clearance properties were compared to Cy5.5, a conventional pentamethine indocyanine now used for biomedical imaging. Results: ZW700-1a, ZW700-1b, and ZW700-1c were synthesized, purified, and analyzed extensively in vitro and in vivo. All molecules had extinction coefficients >= 199,000 M-1 cm(-1), emission >= 660 nm, and stability >= 99 % after 24 h in warm serum. In mice, rats, and pigs, >= 80 % of the injected dose was completely eliminated from the body via renal clearance within 4 h. Either alone or conjugated to a tumor targeting ligand, ZW700-1a permitted dual-channel, high SBR, and simultaneous imaging with 800-nm NIR fluorophores using the FLARE (R) imaging system. Conclusions: Novel 700-nm zwitterionic NIR fluorophores enable dual-NIR image-guided surgery.</P>

서일홍,현웅근,김태원,여희주,김재옥,윤승중 한양대학교 공학기술연구소 1992 공학기술논문집 Vol.1 No.1
A multi-robot controller is designed, where the system allows multiple robots to be controlled simultaneously up to a total of 12 axis. Especially, the control system is designed to be capable of collision avoidance and coordination of multiple robots. And to effectively handle environmental conditions, the control system is designed to be able to integrate the external sensors such as vision, encoder, and force sensors. Also, a set of programming primitives, which permit a programmer to specify coordination tasks, are proposed and discussed.

본 시험은 여러 가지 광물질과 혼합된 크롬 피콜린 산을 첨가한 사료의 급여가 비육돈의 성장, 도체특성, 혈액성상에 미치는 영향을 알아보기 위하여 수행되었다. 개시체중이 69㎏인 총 513두의 비육돈을 돈방당 16∼21두씩 수용하여 사양시험을 수행하였으며, 9마리가 대사시험에 사용되었다. 처리구는 2개의 단백질 수준별 대조구 (Con 12, Cen 14)와 외산 크롬 피콜린산 (CrP-CaCO₃ ; Prince사 제품). 크롬 제오라이트 (CrP-Zeolite 12, 14), 국산 크롬 피콜린산 1 (CrP-CaCO₃; KIST 개발), 크롬 피콜린산-산화아연 (CrP-CaCO₃-ZnO 12, 14) 그리고 국산 크롬 피콜린산 2 (CrP-CaCO₃ ; M. H. Lee 개발)이었다. 성장성적에 있어서는 일당중체량, 일당사료섭취량, 사료효율 등 모든 조사항목에서 처리구간의 차이가 발견되지 않았으나, 등지방 두께는 크롬 피콜린산 첨가에 의해 감소하는 경향이 발견되었고, 이러한 경향은 출하체중이 무거울수륵 뚜렷하게 나타났다. 도체등급은 크롬 제오라이트구와 크롬 피콜린산-산화아연처리구에서 높게 나타났으며, 혈액내 콜레스테를의 함량도 크롬 제오라이트구와 크롬 피콜린산-산화아연처리구에서 대조구에 비해 유의적으로 감소하였다 (p<0.05). 크롬 피콜린산-산화아연처리구와 크롬 피콜린산구에서 건물 및 단백질 소화율이 향상되었다 (p<0.05). This experiment was conducted to investigate the effects of chromium picolinate in different combinations with minerals on growth, carcass characteristics, serum traits and nutrient digestibility in finishing pigs. Five-hundred and thirteen pigs (69.0 ㎏ of initial weight) were assigned to 9 treatments, each containing three replicates of sixteen to twenty-one pigs each. Additional nine pigs were used in a digestion trial. Treatments were two controls (12% CP and 14% CP), foreign CrP-CaCO₃, two CrP-Zeolite (12% CP and 14% CP), domestic CrP-CaCO₃ 1, CrP-CaCO₃-ZnO (12% CP and 14% CP) and domestic CrP-CaCO₃ 2. ADG was not significantly different among the treatments. Tenth rib backfat thickness tended to be decreased by feeding diet with CrP. Carcass grade was improved by using zeolite and CaCO₃ + ZnO along with CrP in diets. Serum cholesterol level was significantly reduced by feeding diets containing CrP with CaCO₃ + ZnO or Zeolite compared with the control. Supplementation of Cr with CrP-CaCO₃ + ZnO or CrP-CaCO₃ in diets significantly improved the digestibility of crude protein and dry matter (p<0.05). The excretion of nitrogen was lower in pigs fed diets containing Cr regardless of the combinations with minerals. The excretion of phosphorus was lowest in the CrP-CaCO₃ + ZnO group which showed the highest phosphorus digestibility.
