We examined the protective effects of Pyropia yezoensis glycoprotein (PYGP) against ethanol-induced gastric damage. The experimental animals were divided into four groups. They were treated with distilled water (control), ethanol alone (EtOH), ethanol + PYGP 150 mg/kg BW (EtOH+150), or ethanol + PYGP 300 mg/kg BW (EtO…
This study was investigated the change of concentration and toxicity of thermally cross-linked superparamagnetic iron oxide nanoparticles (TCL-SPION) on tissues of Sprague-Dawley rats.TCL-SPION at the dose of 15 mg/kg body weight was intravenously injected into the tail vein of the male Sprague-Dawley rats.The fate of…
Spark Plasma Sintering (SPS) of LaFeSi alloy powders was conducted to prepare magnetocaloric La-Fe-Si-based uniform microstructures. Two electrically insulating discs made of alumina were interposed between the punches and powder sample inhibiting the flow of electric current across the powder. This approaching aiming…
Flexible nanostructured and conducting metal-polymer films have been found promising applications in pharmaceuticals and flexible electronics. These could be used as anti-bacterial agent, bio-warfare treatment, or as sensors for environmental monitoring and protection. However, mechanical strength and metal-polymer ad…
In this work, the achievement and characterization of boron-doped nanocrystalline diamond films is presented. A series of experiments varying boron doping levels from 2,000 to 30,000 ppm and film growth times during 6, 10 and 16 h were performed. These films were analyzed by Scanning Electron Microscoy (SEM), Atomic F…

This study aims to provide preliminary data in the field of school uniform and marketing that clothing propensity by groups is considered. This study conducted…
본 연구는 저빈도 반복경두개자기자극(rTMS)이 만성 뇌졸중 환자의 인지기능에 미치는 영향을 알아보기 위해 실시하였다. MMSE-K와 한국어판 BCRS-K를 통해서 선별된 만성 뇌졸중 환자 30명을 대상으로 3개의 군으로 무작위로 나누었다. 실험군 I(n=10)은 소리만 동일시간 적용하게 하였고, 실험군 II(n=10)은 손상 측에 1 Hz rTMS를, 실험군 III(n=10)은 손상반대측에 1 Hz rTMS를 적용하여 주 5회, 1일 20분, 2주간 중재하였다. 인지기능의 변화를 알아보기 위해서 중재 전, 1주 후, 2주 후, 3개월 후 시점에서 CERAD-K 점…
1pp) Creating a high impact journal for research in fluorescence EditorialDear authors, reviewers and readersAs our second year of publication draws to a close, we would like to express our thanks to all who have supported the journal this year, either by choosing to publish their best work with us or by reviewing art…
본 연구에서는, Ni/CNT/ $SiO_2$ 구조의 4H-SiC MIS 캐패시터를 제작하고 전기적 특성을 조사하였다. 이를 통하여 4H-SiC MIS 소자에서 탄소나노튜브의 역할을 분석하고자 하였다. 탄소나노튜브는 이소프로필알코올과 혼합하여 $SiO_2$ 표면에 분산하였다. 소자의 전기적 특성 분석을 위하여 300-500K의 온도 범위에서 소자의 정전용량-전압 특성을 측정하였다. 밴드 평탄화 전압은 양의 방향으로 shift되었다. 정전용량-전압 그래프로부터 계면 포획 전하 밀도 및 산화막 포획 전하 밀도가 유도되었다. 산화막의 상태는 4H-SiC MIS 구조의 계면…
Carbon nanotubes (CNT) are a material with unique properties (mechanical, electrical, electrochemical, etc) allied with low density and high specific area. The present paper studied the electrochemical properties of carbon nanotubes growth by Chemical Vapor Depostion (CVD) technique. The samples were characterized by…
Synthesis of a deuterium-labeled derivative of nitrospirobenzopyran (NSP), one of representative photochromic compounds, has been described. Four deuteriums were successfully introduced on 1-methyl and ${\alpha}$ -methyne relative to spiro-carbon in the title compound with more than 95atom%D purity. Main photodegraded…
In this work the processing of composites containing graphite or hexagonal boron nitride dispersed in a ferrous matrix alloyed with phosphorous was addressed, with the goal of developing self-lubricating sintered materials with high mechanical resistance. Phosphorous is an alloy element characteristic in powder metall…
Collision simulation of river-sea ship is accomplished based on nonlinear finite element method. Firstly, we discuss the development of collision analysis methods including theoretical methods, empirical formula method, experimental techniques and numerical analysis methods, and introduce the Central Difference Method…
Experimentally detected ultrafast spin-avalanches spreading in crystals of molecular (nano)magnets (Decelle et al., Phys. Rev. Lett. 102, 027203 (2009)), have been recently explained in terms of magnetic detonation (Modestov et al., Phys. Rev. Lett. 107, 207208 (2011)). Here magnetic detonation structure is investigat…
Sudden-enlarge tube has important applications in reality lives. The backflow region length in sudden-enlarge tube flows is closely related with its energy loss. In this paper, the characteristics of backflow region length in suddenenlarge oil tube flows are researched. The results show that backflow region length dec…
Photoswitchable ligands are used to control and study complex biological systems such as folding of proteins and peptides, enzymatic reactions or neuronal signaling. They are typically developed by conjugating photochromic compounds to known ligands so that exposure to light results in the change of the binding affini…
