A vision-based off-road alert system (2002)

A vision based system for line warning is proposed to assist drivers in preventing road departures due to a sleep accident or inattention. It is based on monitoring of the 2D motion field generated by the vehicle motion. A prototype analog smart sensor with embedded motion estimation is presented as a new attractive real time implementation of the system.
Using a Class Algebra Ontology To Define Conversions between OWL/SQL/Java Beans (2005)

This paper describes the xml definition of class algebra which is available at http://xbean.cs.ccu.edu.tw/~dan/classAlgebra.xml . A sample user-defined ontology document and instance document are available at http://xbean.cs.ccu.edu.tw/~dan/userOntology.xml and http://xbean.cs.ccu.edu.tw/~dan/userInstances.xml . The class algebra ontology is very similar to the OWL ontology, but it uses its own definition of pointers for non-partOf relations. This simplifies the underlying theory as well as the syntax. The same syntax is used to define the ontology (i.e. the schema) as well as instance documents. The class algebra ontology has sufficient information to enable conversion between class algebra instance documents, SQL tables, and Java persistent objects, all of which can be queried by class algebra queries and updated by class algebra assignment operators, RMI calls, or SOAP method calls. The state-space graph of all possible orderings of class algebra operators is searchable by efficient constraint-based search techniques. Operators include guarded class algebra assignments as well as traditional SOAP or RMI method calls.
Flow-through optical biosensor based on the permanent immobilization of an enzyme and transient retention of a reaction product (1993)

A new sensor based on the twofold immobilization of a catalyst and a reaction product in an optical flow cell is proposed. The packing material of the flow cell consists of two physically distinct layers: an upper layer of controlled-pore glass (CPG) onto which the enzyme is immobilized, and a lower layer of suitable exchanger where the product of the enzymatic reaction is temporarily retained. The performance of the biosensor was tested by immobilizing peroxidase on CPG and retaining the product of the reaction between hydrogen peroxide, 4-aminophenazone, and an aniline derivative on a Sephadex resin. The sensor can be used to monitor hydrogen peroxide and any previous reaction which yields it (e.g., any reaction catalyzed by an oxidase). The biosensor was applied to the determination of hydrogen peroxide and glucose in serum. The features of the determinations (linear ranges between 10 and 200 ng/mL, and RSD values smaller than 2%), in addition to the great consistency of the results with those obtained in the clinical determination of glucose by an AACC method and analyte recoveries between 95 and 105% testify to the excellent performance of the sensor.
Emerging medical treatments for aortic stenosis: statins, angiotensin converting enzyme inhibitors, or both? (2006)

Aortic stenosis is the most common adult heart valve condition seen in the Western world and its incidence continues to rise. No established disease modifying treatments retard progression of the stenotic process. Recent insights into the pathogenesis of calcific aortic stenosis suggest that the disease mimics atherosclerosis. The natural history and progression of calcific aortic stenosis are described with particular emphasis on new and emerging medical treatments that may modify the disease process. In particular, statins and angiotensin converting enzyme inhibitors appear to hold promise but definitive evidence from large clinical trials is awaited.
Utilization of Pine Kraft Lignin in Starch Composites:  Impact of Structural Heterogeneity (1998)

To elucidate the effect of lignin structure on the properties of lignin−starch composites, an industrial pine kraft lignin sample was fractionated by sequential extraction with organic solvents. Three fractions were obtained with different carbohydrate contents, infrared spectra, and molecular size distributions. In addition, an in-depth structural investigation was performed by GC−MS analyses of the low-molecular weight phenolics occurring in the native fractions or obtained by thioacidolysis. The properties of the lignin−starch composites made from pine kraft lignin or its fractions were evaluated, as compared to reference starch films. Although present in small quantities, the low-molecular weight fraction isolated from pine kraft lignin was observed to have a key role in the mechanical properties of the films, mainly as a starch plasticizer. Keywords: Lignin; starch; lignin utilization; lignin−starch composites
Detection of canine echinococcosis by coproantigen ELISA (2010)

To study the canine echinococcosis by coproantigen ELISA method. During the present investigation experimental infection was established using evaginated worms of Echinococcus granulosus (E. granulosus). To check cross reactivity two pups were infected with Taenia hydatigena (T. hydatigena). In order to detect the presence of antigen, hyperimmune sera were raised against excretory-secretory products of adult worms E. chinococcus granulosus. Faecal sample collected either from experimentally infected pups or from other sources were heated at 70 °C to detect heat stable soluble antigen. Pups harbouring less than 104 worms showed negative results. Samples collected from 14 days onwards from experimentally infected animals harbouring more than 104 worms showed positive value. The maximum positive samples were detected in samples collected from in and around slaughter house and the least number of samples were detected positive maintained by dog squad. The affinity purified IgG exhibited promising results for detection of canine echinococcosis by indirect ELISA.
Distributed Clock Synchronization for Wireless Sensor Networks Using Belief Propagation (2011)

In this paper, we study the global clock synchronization problem for wireless sensor networks. Based on belief propagation, we propose a fully distributed algorithm which has low overhead and can achieve scalable synchronization. It is also shown analytically that the proposed algorithm always converges for strongly connected networks. Simulation results show that the proposed algorithm achieves better accuracy than consensus algorithms. Furthermore, the belief obtained at each sensor provides an accurate prediction on the algorithm's performance in terms of MSE.
A regressive structure for on-line computation of arbitrary length DCT-IV and DST-IV transforms (1996)

We demonstrate that the forward and inverse type-IV discrete cosine transform (DCT-IV/IDCT-IV) and type-IV discrete sine transform (DST-IV/IDST-IV) can be efficiently computed by a regressive structure. In our approach, we suggest using the recursive sinusoidal formulas corresponding to the transform kernels of these transforms to obtain an IIR filter structure. The novel structure is then used for parallel computation of arbitrary length DCT-IV/IDCT-IV and DST-IV/IDST-IV. Since the architecture can be highly parallel, simple, and regular, it is most suitable for VLSI implementation. Moreover, we do not need to permute the input sequence, which makes the approach particularly suitable for on-line computation.
특집 : 삼성 X파일 사건이 남긴 과제; 해석론과 입법론: 국회의원의 면책특권과 그 구체화방안 (2013)

이 글은 최근 소위 삼성X파일과 관련하여 원내 발언 내용을 인터넷으로 공개한 노회찬 전의원에게 의원직 상실형을 확정한 대법원의 판결과 관련하여 국회의원의 면책특권의 현대적 의미를 규명하고 헌법재판소가 제시한 반(半)대표제에 부합하는 헌법해석론 및 이를 구체화하기 위한 입법방안을 모색하였다. 대체로 우리나라에서의 면책특권에 관한 논의는 미국의 그것을 원용하는 수준에 그치고 있으나 권력분립의 틀에 충실한 듯한 외관 하에 닉슨행정부의 권력 강화에 기여한 미국의 사례는 절차적 민주주의의 실천을 추구하는 현행헌법의 실질적 국민주권의 관념에 어울리지 않는다. 이에 대법원은 이미 부수행위라는 개념을 개발하여 권위주의적 통치에 의해 형해화되었던 국회의원의 독립성과 자율성을 확보할 수 있는 방안을 마련하였다. 이제 이 부수행위가 의정과정을 국민에게 알리는 기능으로 전환될 수 있도록 면책특권의 보호범위를 확대하는 방안이 모색되어야 한다. 이에 이 글은 국회법 개정안을 중심으로 국회의원과 국민들 간의 소통행위가 면책특권의 보호범위 안에 들어 올 수 있는 입법방안을 모색하였다.
Pneumococcal keratitis: a clinical profile (2003)

Ciprofloxacin therapy can be effective in the treatment of pneumococcal keratitis.
H3 and H4 histone cDNA sequences from<i>Xenopus</i>: a sequence comparison of H4 genes (1982)

Ovarian poly (A) + RNA from Xenopus laevis and Xenopus borealis was used to construct two cDNA libraries which were screened for histone sequences. cDNA clones to H4 mRNA were obtained from both species and an H3 cDNA clone from Xenopus laevis. The complete DNA sequences of these clones have been determined and are presented. These new sequences are compared with other H3 and H4 DNA sequences both in the coding and 3' noncoding regions. We find that there is considerable non-random codon usage in ten H4 genes. In addition there are some sequence similarities in the 3' noncoding regions of H3 and H4 genes.
On the transformation of sulfur‐containing amino acids and peptides to volatile sulfur compounds (VSC) in the human mouth (1997)

Halitosis is most often caused by oral conditions. Volatile sulfur compounds (VSC), constituting the major components of oral malodor, are produced by anaerobic, gram-negative bacteria retained mainly in periodontal pockets or on the tongue dorsum. Sulfur-containing amino acids serve as substrate for these bacteria. VSC have also been found to have unfavorable effect on the tissue. The aim of this study was to examine whether normal, healthy individuals with no history of halitosis were able to produce VSC from cysteine, when applied as a mouthrinse. A further aim of the study was to investigate and compare the potential of other sulfur-containing amino acids and peptides as substrates for oral VSC production and to localize the odor-production sites. A portable sulfide monitor was used for VSC registration. Results showed that all test subjects produced high oral concentrations of VSC upon rinses with cysteine, which thus seems to be a major substrate for VSC production. The other sulfur-containing substrates had much less effect. It was found that the tongue was the major site for VSC production, and that saliva per se caused low VSC production.
An epoxygenase metabolite of arachidonic acid mediates angiotensin II-induced rises in cytosolic calcium in rabbit proximal tubule epithelial cells. (1991)

Previous studies from this and other laboratories have shown that angiotensin II (AII) induces [Ca2+]i transients in proximal tubular epithelium independent of phospholipase C. AII also stimulates formation of 5,6-epoxyeicosatrienoic acid (5,6-EET) from arachidonic acid by a cytochrome P450 epoxygenase and decreases Na+ transport in the same concentration range. Because 5,6-EET mimics AII with regard to Na+ transport, it effects on calcium mobilization were evaluated. [Ca2+]i was measured by video microscopy with the fluorescent indicator fura-2 employing cultured rabbit proximal tubule. AII-induced [Ca2+]i transients were enhanced by arachidonic acid and attenuated by ketoconazole, an inhibitor of cytochrome P450 epoxygenases. Arachidonic acid also elicited a [Ca2+]i transient that was attenuated by ketoconazole. 5,6-EET augmented [Ca2+]i similar to that seen with AII, but was unaffected by ketoconazole. By contrast, the other regioisomers (8,9-, 11,12-, and 14,15-EET) were much less potent. [Ca2+]i transients resulted from influx through verapamil- and nifedipine-sensitive channels. These results suggest a novel mechanism for AII-induced Ca mobilization in proximal tubule involving cytochrome P450-dependent arachidonic acid metabolism and Ca influx through voltage-sensitive channels.
Detoxification of sago trunk hydrolysate using activated charcoal for xylitol production (2011)

Xylitol is one of the alternative natural sweeteners; belong to a group of sugar alcohol. It can be derived from D- xylose which mainly contains in lignocellulose materials. In this study sago trunk cortex was chosen as lignocellulose source due to its availability and abundant in the sago starch processing industry. The production of xylitol includes hydrolysis which breaks the cellulose and hemicellulose polymers to fermentable sugar, mainly xylose, followed by fermentation process which converts the sugars to xylitol. However, some by-products such as furfural and phenolic are released during chemical hydrolysis and inhibit fermentation process. Detoxification procedures were carried out over sago trunk hydrolysates. Powdered activated charcoal was mixed with the hydrolysate at 1% and 2.5% (w/v) and stirred for 30 and 60 minutes at room temperature. The recovery of xylitol was performed using yeast Candida tropicalis in sago trunk cortex hydrolysate. This study describes detoxification methods of sago trunk cortex hydrolysates to improved xylitol production by Candida tropicalis. The effects of 1% and 2.5% (w/v) activated charcoal were identified to the growth and xylitol concentration. This study found that with the application of activated charcoal method, it enabled a reduction of furfural (58%) and total phenolics (78%) compounds. The best conditions was achieved with 2.5% activated charcoal at adsorption time of 60 minutes and the maximum xylitol concentration, xylitol yield and volumetric productivity obtained were 19.53 g l-1, 0.78 g g-1 and 0.37 g l-1 h-1. The value of xylitol yield using the detoxification hydrolysate medium was higher when compared to non-treated medium (0.307 g g-1). This strongly suggests that detoxification method using activated charcoal has a significant impact in xylitol production.

Using Web-Services to Support Collaboration Practices Along the Supply Chain (2006)

In the last years, collaborative planning, forecasting and replenishment (CPFR) has emerged as a promising solution to the increasing need for efficient and effective management of demand in a supply network. However; the current technological framework supporting information sharing and collaboration along the supply chain has a number of limitations, such as the extensive IT restructuring needed for integrating partner information systems and the high cost inherent in the development and deployment of complex collaboration solutions per se. In this paper we suggest a new technological approach for supporting CPFR practices and further suggest an innovative system implementation based entirely on open-source technologies. Our developed prototype facilitates the process of exchanging partner predictions via a host of different operating devices (PC, PDAs, cellphones). The system's backend is supported by various Web-services for automating information flow and collaboration through a supply network.
Cross-protection against lymphocytic choriomeningitis virus mediated by a CD4+ T-cell clone specific for an envelope glycoprotein epitope of Lassa virus (1993)

Recombinant vaccinia virus expressing the Lassa virus (LV) envelope glycoprotein precursor, V-LSGPC, was used to study the basis of LV-induced cross-protective immunity against the closely related arenavirus lymphocytic choriomeningitis virus (LCMV). C3H/HeJ mice primed with V-LSGPC developed neither circulating antibodies nor CD8+ cytotoxic T cells specific for LCMV, yet they resisted a normally lethal LCMV challenge. Spleen cells from such mice gave a proliferative response to LCMV in vitro that was inhibitable by anti-CD4 antibody. Synthetic peptides corresponding to predicted T-cell sites common to the envelope glycoprotein precursor (GP-C) of LV and that of LCMV were used to map the specificity of the proliferative response to an epitope located between amino acids 403 and 417 of LV GP-C. Several CD4+ T-cell clones specific for the 403-417 peptide were isolated and found to produce gamma interferon in response to both the peptide and LCMV. One of these clones, C9, was selected for further study. C9 lysed I-AK-bearing target cells, and when adoptively transferred to C3H/HeJ mice, it was capable of mediating both a peptide-specific delayed hypersensitivity reaction and resistance to lethal LCMV challenge. These collective findings demonstrate, for the first time, that CD4+ T cells can play a major role in arenavirus-specific cross-protective immunity.
Antioxidant and hepatoprotective effects of punicalagin and punicalin on acetaminophen‐induced liver damage in rats (2001)

Punicalagin and punicalin were isolated from the leaves of Terminalia catappa L., a Combretaceous plant distributed throughout tropical and subtropical beaches, which is used for the treatment of dermatitis and hepatitis. Our previous studies showed that both of these compounds exert antioxidative activity. In this study, the antihepatotoxic activity of punicalagin and punicalin on acetaminophen-induced toxicity in the rat liver was evaluated. After evaluating the changes of several biochemical functions in serum, the levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were increased by acetaminophen administration and reduced by punicalagin and punicalin. Histological changes around the hepatic central vein and oxidative damage induced by acetaminophen were also recovered by both compounds. The data show that both punicalagin and punicalin exert antihepatotoxic activity, but treatment with larger doses enhanced liver damage. These results suggest that even if punicalagin and punicalin have antioxidant activity at small doses, treatment with larger doses will possibly induce some cell toxicities.
Liver Regeneration and the Effect of Exogenous Putrescine on Regenerative Activity After Partial Hepatectomy in Cirrhotic Rats (1992)

There are conflicting data regarding the ability of the liver to regenerate after partial hepatectomy in animals and humans with cirrhosis. The purpose of this study was to document liver regeneration after partial hepatectomy in a carbon tetrachloride rat model of cirrhosis and to determine whether exogenous putrescine, a polyamine that has been reported to stimulate liver regeneration in animal models of acute liver failure, enhances regenerative activity in cirrhosis. Liver fibrosis and cirrhosis were produced by weekly intragastric gavage with carbon tetrachloride in 130 adult male rats. Vehicle-gavaged rats (n = 12) served as healthy controls. At surgery and at 4 and 8 hr after 70% hepatectomy, rats received normal saline solution or 1 or 10 mg/kg putrescine by intraperitoneal injection. Another group (n = 32) of carbon tetrachloride-treated rats was given putrescine (100 mg/kg) or normal saline solution twice daily for 10 days before partial hepatectomy and at 0, 4 and 8 hr after partial hepatectomy. Liver regeneration was documented 24 and 48 hr after partial hepatectomy on the basis of restitution of liver mass, ornithine decarboxylase activity and [3H]thymidine incorporation into liver DNA. Automated image analysis of the resected liver specimens separated carbon tetrachloride-treated rats into two subgroups: those with bridging fibrosis (fibrotic group) and those with micronodular cirrhosis (cirrhotic group). Restitution of liver mass and ornithine decarboxylase activity at 24 and 48 hr after partial hepatectomy were similar to carbon tetrachloride-treated rats (both fibrotic and cirrhotic) and vehicle-treated healthy controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Acupoint injection has outstanding effect for treatment of chronic gastritis of gastric blood stasis type and this therapy is worth generalizing and applying.
Syntheses and structures of metal cyanamide compounds (2002)

This thesis describes syntheses and structures of some metal cyanamide compounds, based on "soft cations" of metal elements. In PbNCN, the cyanamide anion exhibits two different C-N bond lengths. Quantum-chemical DFT calculations prove that the cyanamide anion is comparatively easy to distort. Two modification of mercury cyanamide has been synthesized by controlling the pH value. The X-ray analysis shows that Hg atoms and the one end of NCN units form zigzag chains in HgNCN(II), and two C-N bond lengths are significantly different. In HgNCN(I) NCN unit bonds to Hg atoms from the both sides and the two C-N bond lenghs are almost identical. The crystal structures of Hg2(NCN)Cl2 and Hg3(NCN)2Cl2 show that there are sharing edged 20-membered rings formed by [Hg3(NCN)2]2+ as a backbone, but the cavities of the rings are very flexible. Ag2NCN, as an example of a transition metal cyanamide, shows that NCN unit has mixed character of "N=C=N" and "N?C-N". The structure of Ag(H4N4C2)3NO3 shows that two dicyandiamides behave as a mono-dentate ligand through nitrile nitrogen atoms and the third dicyandiamide locates just in the vacant site binding by hydrogen bonds. In Ni(NCNH2)4Cl2, Co(NCNH2)4Cl2 and Cu(NCNH2)4Cl2, Ni2+, Co2+ or Cu2+ are octahedrally coordinated by four equatorial H2NCN molecules and two axial chloride ions. Ni(NCNH2)4Cl2/ Co(NCNH2)4Cl2 are Curie paramagnets with two/three unpaired electrons.
The value of lesion cross-sectional area determined by quantitative coronary angiography in assessing the physiologic significance of proximal left anterior descending coronary arterial stenoses. (1984)

The results of previous work from this laboratory have shown a poor correlation between percent stenosis (determined visually with calipers) and the coronary reactive hyperemic response (an index of maximal coronary vasodilator capacity) determined during cardiac surgery. This study was performed to determine whether other parameters of lesion severity could predict the reactive hyperemic response and thus the hemodynamic significance of coronary stenoses in human beings. Twenty-three patients with lesions in the proximal left anterior descending coronary artery were studied. To account for differences in expected vessel size, patients with large diagonal branches (greater than one-half the diameter of the left anterior descending artery) arising before the lesion were excluded. Computer-assisted quantitative coronary angiography was used to measure percent diameter stenosis, percent area stenosis, and minimal stenosis cross-sectional area. With a pulsed Doppler velocity probe, reactive hyperemic responses were recorded after a 20 sec coronary occlusion of the left anterior descending artery at cardiac surgery before cardiopulmonary bypass and were quantified by the peak/resting velocity ratio (normal greater than 3.5:1). Percent area stenosis ranged from 7% to 54% for vessels with normal reactive hyperemic responses and from 27% to 94% for vessels with abnormal reactive hyperemic responses. With both percent diameter stenosis and percent area stenosis there was substantial overlap between vessels with normal and abnormal reactive hyperemic responses. In contrast, nine of nine vessels with normal reactive hyperemic responses had lesion minimal cross-sectional areas of greater than 3.5 mm2 and 13 of 14 vessels with abnormal reactive hyperemic responses had minimal cross-sectional areas of less than 3.5 mm2.(ABSTRACT TRUNCATED AT 250 WORDS)
