소아청소년 제2형 당뇨병의 진단과 치료
Full text linkBackground: Type 2 diabetes mellitus (T2DM) is one of the most prevalent chronic diseases, and its increasing prevalence in children and adolescents is a worldwide problem. In the past ten years, the prevalence of T2DM has increased by more than two-fold. This review focuses on the recent advances in the diagnosis and treatment of T2DM in children and adolescents. Current Concepts: Pancreatic beta-cell dysfunction and insulin resistance are the key factors contributing to the development of T2DM. The diagnosis of T2DM is based on serum glucose levels or hemoglobin A1c levels. Currently, only insulin, metformin, and liraglutide (glucagon-like peptide-1 receptor agonist) have been approved for the treatment of T2DM in children and adolescents. Discussion and Conclusion: Early diagnosis and prevention of T2DM in children and adolescents are essential. Furthermore, the treatment of T2DM in children and adolescents is limited, unlike in adults. Further research is needed to evaluate the long-term efficacy and safety of the available treatments in children and adolescents with T2DM
Central precocious puberty: is routine brain MRI screening necessary for girls?: Commentary on “Brain magnetic resonance imaging (MRI) findings in central precocious puberty patients: is routine MRI necessary for newly diagnosed patients?”
Full text linkSEGMENTAL CORRECTIVE TRAINING FOR HIDDEN MARKOV MODEL PARAMETER-ESTIMATION IN SPEECH RECOGNITION
No full textA modified corrective training method using state segment informations in the hidden Markov model is presented. The proposed algorithm is shown to result in a higher recognition rate than the conventional corrective training method and requires less computation
POSTPROCESSOR USING FUZZY VECTOR QUANTIZER IN HMM-BASED SPEECH RECOGNITION
No full textA postprocessor using fuzzy vector quantisation (FVQ) in HMM-based speech recognition is presented. A method to reduce the amount of computation in the FVQ postprocessor is also proposed. We show that the proposed method results in a higher recognition rate with almost the same amount of computation compared to the conventional Viterbi scoring method
LIQUID-LIQUID EQUILIBRIA FOR TRITON X-100 PLUS WATER AS A FUNCTION OF PRESSURE
No full textLiquid-liquid equilibria were measured at pressures of 0.0, 50.0, 100.0, and 150.0 bar for Triton X-100 + water. The lower critical solution temperature of the Triton X-100 + water binary system is about 339 K at all pressures investigated
Liquid-liquid equilibria and partitioning of o-chlorophenol in ethylene glycol monobutyl ether plus water, diethylene glycol monohexyl ether plus water, and poly(oxyethylene(4)) lauryl ether plus water
No full textLiquid-liquid equilibria of ethylene glycol monobutyl ether (C(4)E(1)) + water and diethylene glycol monohexyl ether (C(6)E(2)) + water at atmospheric pressure were measured for temperature ranges of 322.8 K and 273.2 K to 382.5 K, respectively. The lower critical solution temperature (LCST) and upper critical solution temperature (UCST) of C(4)E(1) + water were determined to be 322.8 K and 402.8 K respectively. The LCST of C(6)E(2) + water is 273.2 K, while the corresponding UCST does not exist. The equilibrium compositions of o-chlorophenol partitioning in the top and bottom phases of the three binary C(4)E(1) + water, C(6)E(2) + water, and poly(oxyethylene(4)) lauryl ether (C(12)E(4)) + water mixtures were also measured
Bounds on the mass and coupling constant of radion in the Randall-Sundrum theory
No full textAssuming the Goldberger-Wise mechanism, we investigated the effective potential at the one-loop level in the Randall-Sundrum theory. We found the lower and upper bounds of the radion mass m(phi) and the radion-SM coupling constant, 0.8 GeV less than or similar to m(phi) less than or similar to 260 GeV and 1400 GeV less than or similar to Lambda (phi) less than or similar to 1500 GeV for the one-loop level potential. These bounds were determined from two constraints of warp factor = O(M-W/M-Pl) and Higgs vev similar or equal to 246 GeV, which can produce strong bounds of m(phi) and Lambda (phi). it is phenomenologically important that the one-loop allowed upper bound of the radion mass is about five times larger than the tree-level one, but the radion is still lighter than the Kaluza-Klein modes.

High-pressure phase equilibria for the carbon dioxide 2-pentanol and carbon dioxide water 2-pentanol systems
No full textHigh pressure vapor-liquid equilibria for the binary carbon dioxide-2-pentanol system are measured at 313.2 K. The phase equilibrium apparatus used in this work is of the circulation type in which the coexisting phases are recirculated, on-line sampled, and analyzed. The critical pressure and corresponding mole fraction of carbon dioxide at 313.2 K are found to be 8.67 MPa and 0.985, respectively, for this binary system. The phase equilibria for the ternary carbon dioxide-water-2-pentanol system are also measured at 313.2 K and at pressures of 2.0, 4.0, 6.0, 8.0, and 8.64 MPa. The ternary carbon dioxide-2-pentanol-water systems show three LLV phases over the range of pressure up to 8.64 MPa. The binary experimental equilibrium data are correlated with the Redlich-Kwong, Soave-Redlich-Kwong, Peng-Robinson, and Patel-Teja equations of state with two different mixing rules, the van der Waals and the Panagiotopoulos-Reid mixing rules. The binary experimental data are well correlated by using three equations of state and corresponding mixing rules. (C) 1998 Elsevier Science B.V. All rights reserved
