검도 역사성을 통한 스포츠 검도와 전통검도의 비교 (2004)

patriotism. As time goes by, the change of its technical and training have been sluggish. For the purpose of the its development, it is important for us to understand the history of Kumdo. In addition, there should be enough discussion on Sports Kumdo and Traditional Kumdo. The steps toward its developement are below. First, Korean Kumdo technical had been to Japan and its transformed sports using long bamboo sword had crossed to Chosun. Second, while Sports Kumdo is man to man style including the functional training and rapid speed. Traditional Kumdo is natural one to train body and mind including, various are of fencing. Third, Sports Kumdo is to win others but Traditional Kumdo is to improve themselves after the struggle with oneself. Fourth, the former has a focus on the striking method on the contrary that the latter has an emphasis on both the art of fencing using wood and the art of cutting of fencing using sword. Fifth, Sports Kumdo is for the minor, but Traditional Kumdo is for the common. Sixth, considering that sports Kumdo hardly kill partner and play fair, it reflects the spirits through fencing sports which are also modern sports spirits. It is said possibly that the Kumdo base on the respect for each other through the art of fencing. That is, it make our spine and our society better. Also, though the respect for each other there can be raised agreement of spirit and body. Therefore we must make efforts to recreate original Korean Kumdo by using two kinds of Kumdo and to unify the training course.
N-acetylcysteine as an antidote in methylmercury poisoning. (1998)

Methylmercury is a ubiquitous environmental pollutant and potent neurotoxin. Treatment of methylmercury poisoning relies almost exclusively on the use of chelating agents to accelerate excretion of the metal. The present study demonstrates that oral administration of N-acetylcysteine (NAC), a widely available and largely nontoxic amino acid derivative, produces a profound acceleration of urinary methylmercury excretion in mice. Mice that received NAC in the drinking water (10 mg/ml) starting at 48 hr after methylmercury administration excreted from 47 to 54% of the 203Hg in urine over the subsequent 48 hr, as compared to 4-10% excretion in control animals. When NAC-containing water was given from the time of methylmercury administration, it was even more effective at enhancing urinary methylmercury excretion and at lowering tissue mercury levels. In contrast, excretion of inorganic mercury was not affected by oral NAC administration. The ability of NAC to enhance methylmercury excretion when given orally, its relatively low toxicity, and is wide availability in the clinical setting indicate that it may be an ideal therapeutic agent for use in methylmercury poisoning.
Light field compression using homography and 2D warping (2012)

This paper describes a new method for light field compression that exploits inter-view correlation. The proposed method uses homography and 2D warping to predict views and does not require additional camera parameters or a 3D geometry model. The method utilizes angular shift between views, which is neglected in conventional motion compensation methods. Results indicate improved coding efficiency of the proposed method over traditional motion compensation schemes. A full light field coder based on video-compression demonstrates 1-1.5 dB additional improvement in PSNR, or equivalently a 4-12% additional reduction in bitrate when the new method is introduced as a prediction mode.
Evidence for Differential Reflex Regulation of Cholinergic and Noncholinergic Parasympathetic Nerves Innervating the Airways (2002)

The hypothesis that cholinergic and nonadrenergic, noncholinergic parasympathetic nerves innervating the airways are subject to differential reflex regulation was addressed. Pronounced contractile and relaxant parasympathetic reflex responses could be evoked by intravenous histamine, laryngeal mucosal application of capsaicin, inhaled capsaicin, or electrical stimulation of the vagal afferent nerves projecting to the esophagus and abdominal viscera. These data suggest that activation of multiple vagal afferent nerve subtypes can initiate both cholinergic and noncholinergic parasympathetic reflexes in the airways. Conversely, hypoxia or activation of the diving response from the nose evoked only cholinergic contractile reflexes. All contractile and relaxant responses evoked by these stimuli were absent in vagotomized animals or in animals pretreated with the ganglionic blocker trimethaphan, confirming their reflex and parasympathetic nature. The data indicate that cholinergic and noncholinergic parasympathetic nerves regulating airway caliber in guinea pigs are comprised of two distinct parasympathetic pathways that are subject to differential reflex regulation. This previously unrecognized complexity of autonomic regulation of airway caliber has potentially important implications for the mechanisms of airways hyperresponsiveness.
Primary Multiplication Site of the Vaccinia-rabies Glycoprotein Recombinant Virus Administered to Foxes by the Oral Route (1990)

The primary multiplication site of VVTGgRAB, a recombinant vaccinia virus (VV) expressing the rabies virus G glycoprotein, was studied in comparison with that of the parental VV Copenhagen strain, after oral administration to foxes. Foxes were fed with 10(8) TCID50 of either VVTGgRAB or VV and were sacrificed 12, 24, 48 or 96 h after inoculation. Both viruses were detected by viral isolation in the tonsils during the first 48 h after inoculation at titres between 10(2) and 10(4.3) TCID50/ml. Indirect immunofluorescence confirmed the presence of the virus in tonsils of some of the foxes. The polymerase chain reaction allowed the detection of VVTGgRAB in the tonsils of both of two foxes tested after 24 h, three of three foxes after 48 h, in the buccal mucosa of one of two foxes tested after 24 h and two of three foxes after 48 h and in the soft palate of one of two foxes tested after 24 h and one of three foxes after 48 h. VV was detected in the tonsils of one fox tested after 48 h, in the buccal mucosa of another fox tested after 24 h, and in the first fox after 48 h by the same reaction. Foxes were inoculated with virus isolated from fox tonsils 24 h after oral administration (with or without cell culture amplification) to perform back passages. No virus could be isolated in either case after this passage. The innocuity of VVTGgRAB was also demonstrated when foxes were inoculated with passaged virus.
MBNL1 and CUGBP1 modify expanded CUG-induced toxicity in a Drosophila model of myotonic dystrophy type 1 (2006)

Myotonic dystrophy type 1 (DM1) is a neuromuscular disorder caused by a CTG expansion in the 3' UTR of the dystrophia myotonica protein kinase (DMPK) gene. It has been hypothesized that the pathogenesis in DM1 is triggered by a toxic gain of function of the expanded DMPK RNA. This expanded RNA is retained in nuclear foci where it sequesters and induces alterations in the levels of RNA-binding proteins (RNA-BP). To model DM1 and study the implication of RNA-BP in CUG-induced toxicity, we have generated a Drosophila DM1 model expressing a non-coding mRNA containing 480 interrupted CUG repeats; i.e. [(CUG)20CUCGA]24. This (iCUG)480 transcript accumulates in nuclear foci and its expression leads to muscle wasting and degeneration in Drosophila. We also report that altering the levels of two RNA-BP known to be involved in DM1 pathogenesis, MBNL1 and CUGBP1, modify the (iCUG)480 degenerative phenotypes. Expanded CUG-induced toxicity in Drosophila is suppressed when MBNL1 expression levels are increased, and enhanced when MBNL1 levels are reduced. In addition, (iCUG)480 also causes a decrease in the levels of soluble MBNL1 that is sequestered in the CUG-containing nuclear foci. In contrast, increasing the levels of CUGBP1 worsens (iCUG)480-induced degeneration even though CUGBP1 distribution is not altered by the expression of the expanded triplet repeat. Our data supports a mechanism for DM1 pathogenesis in which decreased levels of MBNL and increased levels of CUGBP mediate the RNA-induced toxicity observed in DM1. Perhaps more importantly, they also provide proof of the principle that CUG-induced muscle toxicity can be suppressed.
Detachment of nanotubes from a polymer matrix (2002)

A technique to investigate the adhesion of carbon nanotubes to a polymer matrix is described. Carbon nanotubes bridging across holes in an epoxy matrix have been drawn out using the tip of a scanning probe microscope while recording the forces involved. A full force-displacement trace could be recorded and correlated with transmission electron micrographs observations prior and subsequent to the tip action. Based on these experiments, an approximate calculation of the nanotube-polymer interfacial shear strength has been performed.
Automatic Modal Wavefront Estimation and Correction for Optical Aberration (2018)

Modal estimation of aberration can quantify the amount of aberration, which plays an important role in optical system optimization, aberration correction, and so on. Here, we propose a simple but effective method to find the modal wavefront of aberration. Once the aberrated wavefront has been detected, it will be automatically analyzed with a method based on one-dimensional standard polynomial fitting. According to the analysis, the modal wavefront and the property of aberration can be obtained for further studies. Here, for example, we show that it can be used to calculate the optimal correction wavefront. Experiments were implemented to testify the correctness and effectiveness of this method. This method provides users another option for aberration interpretation.
Pharmacology of dopamine agonists in the treatment of Parkinson’s disease (2002)

There is now increasing use of dopamine agonists as effective early monotherapy in the treatment of Parkinson's disease (PD). Dopamine agonists can induce an antiparkinsonian effect through actions on either D(1)-like or D(2)-like dopamine receptors, and the multiple receptor subtypes present in the brain may provide further opportunities to improve the treatment of PD. Functional interactions exist between D(1)- and D(2)-like receptors, and adaptive changes occur after denervation and repeated administration of a dopamine agonist. Long-acting dopamine agonists produce a lower incidence of dyskinesia than levodopa (L-dopa) when they are used as monotherapy in either PD or in drug-naïve 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated primates. Continuous dopaminergic stimulation appears less likely to prime basal ganglia for involuntary movements compared with drugs, such as L-dopa, that produce pulsatile stimulation. However, once priming has occurred, dopamine agonists produce dyskinesia identical to that of L-dopa. Continuous administration of long-acting dopamine agonists may reverse the priming process initiated by L-dopa, markedly decreasing dyskinesia intensity with a minimal loss of antiparkinsonian activity, at least in MPTP-treated primates. Dopamine receptors in brain areas other than the striatum, such as the globus pallidus and subthalamic nucleus, and in the mesolimbic and mesocortical regions may also contribute to antiparkinsonian activity of dopamine agonists and their associated side effects. The future potential of dopamine agonists may lie in the selective stimulation of dopamine receptor subtypes in different brain areas and through the actions of partial dopamine agonists and drugs that normalize dopamine receptor function.
Insulin infusion and serum potassium in normal subjects. (1987)

Two groups of healthy males of normal body mass index underwent hyperinsulinaemic glucose clamp procedures during studies of insulin resistance. Insulin was infused for 2 consecutive 100 minute periods at 40 and 400 mU.m-2.min-1, plasma glucose being maintained by 20% dextrose infusion via a Biostator. One group received 20 mmol/l potassium chloride in the dextrose infusate, calculated to replace the extracellular potassium deficit due to the action of insulin on potassium flux. Despite this, serum potassium fell equally in both groups in response to each level of insulin infusion.
The effect of silicon on the glass forming ability of the Cu47Ti34Zr11Ni8 bulk metallic glass forming alloy during processing of composites (1998)

Composites of the Cu47Ti34Zr11Ni8 bulk metallic glass, reinforced with up to 30 vol % SiC particles are synthesized and characterized. Results based on x-ray diffraction, optical microscopy, scanning Auger microscopy, and differential scanning calorimetry (DSC) are presented. During processing of the composites, a TiC layer forms around the SiC particles and Si diffuses into the Cu47Ti34Zr11Ni8 matrix stabilizing the supercooled liquid against crystallization. The small Si addition between 0.5 and 1 at. % increases the attainable maximum thickness of glassy ingots from 4 mm for Cu–Ti–Zr–Ni alloys to 7 mm for Cu–Ti–Zr–Ni–Si alloys. DSC analyses show that neither the thermodynamics nor the kinetics of the alloy are affected significantly by the Si addition. This suggests that Si enhances the glass forming ability by chemically passivating impurities such as oxygen and carbon that cause heterogeneous nucleation in the melt.
The detection and consequences of anxiety in clinical depression. (1997)

Anxiety symptoms and comorbid anxiety are common in depressive syndromes, and there is evidence they are associated with increased severity of depression and a poorer outcome. Anxiety and agitation symptoms also appear to be an acute risk factor for suicide in patients who have major affective disorder, an observation that has been supported by a number of biological correlates. Rapid and aggressive treatment of these anxiety/agitation symptoms with suitable antidepressants or benzodiazepines should be considered in order to avoid the immediate risk of suicide and to permit successful treatment of the affective disorder.
An Empirical Analysis of Search Engine Advertising: Sponsored Search in Electronic Markets (2009)

The phenomenon of sponsored search advertising—where advertisers pay a fee to Internet search engines to be displayed alongside organic (nonsponsored) Web search results—is gaining ground as the largest source of revenues for search engines. Using a unique six-month panel data set of several hundred keywords collected from a large nationwide retailer that advertises on Google, we empirically model the relationship between different sponsored search metrics such as click-through rates, conversion rates, cost per click, and ranking of advertisements. Our paper proposes a novel framework to better understand the factors that drive differences in these metrics. We use a hierarchical Bayesian modeling framework and estimate the model using Markov Chain Monte Carlo methods. Using a simultaneous equations model, we quantify the relationship between various keyword characteristics, position of the advertisement, and the landing page quality score on consumer search and purchase behavior as well as on advertiser's cost per click and the search engine's ranking decision. Specifically, we find that the monetary value of a click is not uniform across all positions because conversion rates are highest at the top and decrease with rank as one goes down the search engine results page. Though search engines take into account the current period's bid as well as prior click-through rates before deciding the final rank of an advertisement in the current period, the current bid has a larger effect than prior click-through rates. We also find that an increase in landing page quality scores is associated with an increase in conversion rates and a decrease in advertiser's cost per click. Furthermore, our analysis shows that keywords that have more prominent positions on the search engine results page, and thus experience higher click-through or conversion rates, are not necessarily the most profitable ones—profits are often higher at the middle positions than at the top or the bottom ones. Besides providing managerial insights into search engine advertising, these results shed light on some key assumptions made in the theoretical modeling literature in sponsored search.
Genetics and regulation of two distinct haem-uptake systems, phu and has, in Pseudomonas aeruginosa The GenBank accession numbers for the sequences reported in this paper are AF055999, AF127222, and AF127223. (2000)

A gene cluster similar to haem iron uptake loci of bacterial pathogens was identified in Pseudomonas aeruginosa. This phu locus ('Pseudomonas haem uptake') consisted of the phuR receptor gene and the phuSTUVW operon encoding a typical ABC transporter. Expression of phuR and phuSTUVW from mapped transcriptional-start sites occurred under iron-restricted growth conditions and was directly controlled by the Fur protein. Binding of Fur was demonstrated by DNase footprinting of two adjacent 'Fur boxes' that overlapped both the phuR and phuSTUVW promoters. Two tandem repeats of 154 bp were identified downstream of the phuSTUVW operon, each of which contained a strong Fur-dependent promoter driving expression of iron-regulated RNAs antisense to phuSTUVW. Mutant strains with deletions in phuR and phuSTUV showed greatly reduced growth with either haem or haemoglobin as the only iron source: the defects were complemented by plasmids harbouring the phuR or the phuSTUV genes, respectively. Deletions of phuW or of the tandem repeats had only minor effects on haem utilization. The remaining haem and haemoglobin uptake still observed in the deltaphuR or deltaphuSTUV deletion mutants was due to a second haem-acquisition system, has, which was also under the direct control of Fur. This second haem-receptor gene, hasR, was identified upstream of and in an operon with hasA, encoding a haem-binding extracellular protein. A deltahasR mutant also exhibited decreased utilization of haem and haemoglobin, and a deltaphuR deltahasR double mutant was virtually unable to take up either compound. Both the PhuR and HasR proteins were detected in the outer-membrane fraction of P. aeruginosa grown in low-iron media. Taken together, the evidence suggests that the phu and has loci encode two distinct systems required for the acquisition of haem and haemoglobin in P. aeruginosa.
Conjoining soft-core FPGA processors (2006)

Soft-core programmable processors on field-programmable gate arrays (FPGAs) can be custom synthesized to instantiate only those hardware units, such as multipliers and floating-point units, that an application requires to meet performance demands, thus minimizing soft-core size on the FPGA. Conjoining processors, meaning to share hardware units among two or more processors, can further reduce soft-core size, leaving more resources for other circuits such as custom coprocessors. Using Xilinx MicroBlaze coprocessors and standard embedded system benchmarks, we show that conjoining two processors can provide 16% processor size reductions on average, with less than 1% cycle count overhead. We introduce an efficient dynamic-programming-based exploration method to find the best custom instantiation of hardware units, considering both standalone and conjoined options, for soft-core processors.
Changes in the transmembrane region of the human immunodeficiency virus type 1 gp41 envelope glycoprotein affect membrane fusion (1990)

The charged amino acids near or within the membrane-spanning region of the human immunodeficiency virus type 1 gp41 envelope glycoprotein were altered. Two mutants were defective for syncytium formation and virus replication even though levels of envelope glycoproteins on the cell or virion surface and CD4 binding were comparable to those of the wild-type proteins. Thus, in addition to anchoring the envelope glycoproteins, sequences proximal to the membrane-spanning gp41 region are important for the membrane fusion process.
Administration of interleukin-6 stimulates multilineage hematopoiesis and accelerates recovery from radiation-induced hematopoietic depression (1991)

Hematopoietic depression and subsequent susceptibility to potentially lethal opportunistic infections are well-documented phenomena following radiotherapy. Methods to therapeutically mitigate radiation-induced myelosuppression could offer great clinical value. In vivo studies in our laboratory have demonstrated that interleukin-6 (IL-6) stimulates pluripotent hematopoietic stem cell (CFU-s), granulocyte-macrophage progenitor cell (GM-CFC), and erythroid progenitor cell (CFU-e) proliferation in normal mice. Based on these results, the ability of IL-6 to stimulate hematopoietic regeneration following radiation-induced hematopoietic injury was also evaluated. C3H/HeN female mice were exposed to 6.5 Gy 60Co radiation and subcutaneously administered either saline or IL-6 (1,000 micrograms/kg) on days 1 through 3 or 1 through 6 postexposure. On days 7, 10, 14, 17, and 22, femoral and splenic CFU-s, GM-CFC, and CFU-e contents and peripheral blood white cell, red cell, and platelet counts were determined. Compared with saline treatment, both 3-day and 6-day IL-6 treatments accelerated hematopoietic recovery; 6-day treatment produced the greater effects. For example, compared with normal control values (N), femoral and splenic CFU-s numbers in IL-6-treated mice 17 days postirradiation were 27% N and 136% N versus 2% N and 10% N in saline-treated mice. At the same time, bone marrow and splenic GM-CFC values were 58% N and 473% N versus 6% N and 196% N in saline-treated mice; bone marrow and splenic CFU-e numbers were 91% N and 250% N versus 31% N and 130% N in saline-treated mice; and peripheral blood white cell, red cell, and platelet values were 210% N, 60% N, and 24% N versus 18% N, 39% N, and 7% N in saline-treated mice. These studies demonstrate that therapeutically administered IL-6 can effectively accelerate multilineage hematopoietic recovery following radiation-induced hematopoietic injury.
A chemically explicit model for the molecular mechanism of the F1F0 H+-ATPase/ATP synthases. (1986)

A general hypothesis for the molecular mechanism of membrane transport based on current knowledge of protein structure and the nature of ligand-induced protein conformational changes has recently been proposed [Scarborough, G. A. (1985) Microbiol. Rev. 49, 214-231]. According to this hypothesis, the essential reaction undergone by all proteinaceous transport catalysts is a ligand-induced hinge-bending-type conformational change that results in the transposition of binding-site residues from access on one side of the membrane to access on the other side. Subsequent release and/or alteration of the ligand or ligands that induce the conformational change facilitates the converse conformational change, which returns the binding-site residues to their original position. With this simple cyclic ligand-dependent gating process as a central feature, biochemically orthodox mechanisms for virtually all known transporters are readily conceived. In this article, a chemically explicit model for the molecular mechanism of the F1F0 H+-ATPase/ATP synthases of mitochondria, bacteria, and chloroplasts, formulated within the guidelines of this general transport paradigm, is presented. At least three points of potential interest arise from this exercise. First, with the aid of the model, it is possible to visualize how energy transduction catalyzed by these enzymes might proceed, with no major events left unspecified. Second, explicit possibilities as to the molecular nature of electric field effects on the transport process are raised. And finally, it is shown that enzyme conformational changes, energy-dependent binding-affinity changes, and several other related phenomena as well, need not be taken as evidence of "action at a distance" or indirect energy coupling mechanisms, as is sometimes assumed, because such events are also integral features of the mechanism presented, even though all of the key reactions proposed for both ATP-driven proton translocation and proton translocation-driven ATP synthesis occur at the enzyme active site.
