연구논문 : 청소년의 자기통제력이 비행과 범죄에 미치는 영향: 패널자료를 이용한 인과성 및 일반성 검증 (2006)

본 연구는 자기통제력이 비행과 범죄의 원인이라는 갓프레드슨과 허쉬(Gottfredson and Hirschi, 1990)의 주장을 한국청소년패널조사(KYPS) 자료를 이용하여 시간적 우선성 조건을 충족시킨 가운데 검증하였다. 또한 자기통제이론이 다양한 종류의 비행과 범죄를 설명할 수 있다는 일반이론 주장도 함께 검증하였다. 분석결과 1차년도에 측정한 자기통제력은 2차년도에 측정한 청소년의 지위비행, 범죄, 남 괴롭히기를 설명할 뿐만 아니라 컴퓨터 관련 일탈도 설명하는 것으로 밝혀져서 자기통제이론의 인과성과 일반성 주장이 경험적 지지를 받았다. 그러나 독립변수를 1차년도 자료로 하고 종속변수인 비행과 범죄를 2차년도 자료로 하였을 때의 설명력이 1차년도의 횡단자료 분석 때보다 상당히 낮게 나타나 그 원인에 대한 가능성을 논의하였다. 제기된 설명 가운데 KYPS의 설문조사방법이 1차년도 조사에서 사용한 학급단위의 집단면접조사방식에서 2차년도부터 개별접촉을 통한 대인면접 조사방식으로 바뀌면서 응답자들이 자신들이 저지른 비행과 범죄경험을 숨기거나 축소 보고하게 되고, 그 결과로 종속변수의 변량이 크게 감소했을 가능성에 대해서는 추가적인 연구가 필요하다.
A novel mathematical model of protein-bound uremic toxin kinetics during hemodialysis (2017)

Protein-bound uremic toxins (PBUTs) are difficult to remove by conventional hemodialysis; a high degree of protein binding reduces the free fraction of toxins and decreases their diffusion across dialyzer membranes. Mechanistic understanding of PBUT kinetics can open new avenues to improve their dialytic removal. We developed a comprehensive model of PBUT kinetics that comprises: (1) a three-compartment patient model, (2) a dialyzer model. The model accounts for dynamic equilibrium between protein, toxin, and the protein-toxin complex. Calibrated and validated using clinical and experimental data from the literature, the model predicts key aspects of PBUT kinetics, including the free and bound concentration profiles for PBUTs and the effects of dialysate flow rate and dialyzer size on PBUT removal. Model simulations suggest that an increase in dialysate flow rate improves the reduction ratio (and removal) of strongly protein-bound toxins, namely, indoxyl sulfate and p-cresyl sulfate, while for weakly bound toxins, namely, indole-3-acetic acid and p-cresyl glucuronide, an increase in blood flow rate is advantageous. With improved dialyzer performance, removal of strongly bound PBUTs improves gradually, but marginally. The proposed model can be used for optimizing the dialysis regimen and for in silico testing of novel approaches to enhance removal of PBUTs.
Influence of Coupling Agents on Melt Flow Behavior of Natural Fiber Composites (2007)

Abstract The influence of coupling agents on the melt rheological properties of natural fiber composites has been investigated in this work using capillary and rotational rheometers. Scanning electron microscopy was also employed to supplement the rheological data. It was found that molecular weight and molecular weight distribution of the polymer matrix and coupling agent characteristics influence the filler wetting and the melt flow properties of the filled composites. Generally, low molecular weight and narrow molecular weight distribution polyethylene matrix provides relatively larger increase of the viscosity of the composites. Coupling agents tend to increase the resistance to shearing, but wall slip effects may interfere with the measured values, especially at very high filler loadings. Entrance pressure loss in capillaries is also influenced by polymer matrix and coupling agent used. magnified image

A 200-MFLOPS 100-MHz 64-b BiCMOS vector-pipelined processor (VPP) ULSI (1991)

The first single-chip 64-b vector-pipelined processor (VPP) ULSI is described. It executes vector operations indispensable to high-speed scientific computation. The VPP ULSI attains a 200-MFLOPS peak performance at a 100-MHz clock frequency. This extremely high performance is made possible by the integration on the VPP of a 64-b five-stage pipelined adder/shifter, a 64-b five-stage pipelined multiplier/divider/logic operation unit, and a 40-kb register file. Various new high-speed circuit techniques have been also developed for 100-MHz operations. The chip, which was fabricated with a 0.8- mu m BiCMOS and triple-layer metallization process technology, has a 17.2-mm*17.3-mm area and contains about 693 K transistors. It consumes 13.2 W at a 100-MHz clock frequency with a single 5-V power supply.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Extraction of accurate behavioral models for power amplifiers with memory effects using two-tone measurements (2003)

This paper proposes a system-level behavioral model for RF power amplifiers (PAs) that exhibit memory effects. PAs with memory effects are shown to have two-tone intermodulation distortion (IMD) levels that vary depending on tone-spacing. Thus, typical single tone extracted AM/AM and AM/PM characteristics cannot accurately model PA memory effects. By varying the frequency spacing of two-tone signals, envelope frequency dependent transfer functions can be derived. Using these transfer functions, a behavioral model is developed which is based on the parallel-cascade linear and nonlinear (LN) system. This model gives more accurate results in predicting the behavior of PAs with memory effects close to the carrier frequency. The model is validated by comparing the predicted and measured adjacent channel power ratio (ACPR) of a CDMA signal amplified by a high power class-AB PA. It is found that the parallel cascade model improves ACPR prediction accuracy by as much as 4 dB compared to the single tone derived memoryless model.

Methane storage in metal–organic frameworks (2014)

Natural gas (NG), whose main component is methane, is an attractive fuel for vehicular applications. Realization of safe, cheap and convenient means and materials for high-capacity methane storage can significantly facilitate the implementation of natural gas fuelled vehicles. The physisorption based process involving porous materials offers an efficient storage methodology and the emerging porous metal-organic frameworks have been explored as potential candidates because of their extraordinarily high porosities, tunable pore/cage sizes and easily immobilized functional sites. In this view, we provide an overview of the current status of metal-organic frameworks for methane storage.
Eddy current sensing using planar coils (2012)

Sensors are used in various everyday practices, and therefore, there are different types of sensors suitable for innumerable applications. The type of sensor discussed in this paper is the proximity sensor based on eddy current theory, which measures the distance between the sensor and the target plate with no physical contact [1].
Phonological mismatch and explicit cognitive processing in a sample of 102 hearing-aid users (2008)

Rudner et al (2008) showed that when compression release settings are manipulated in the hearing instruments of Swedish habitual users, the resulting mismatch between the phonological form of the input speech signal and representations stored in long-term memory leads to greater engagement of explicit cognitive processing under taxing listening conditions. The mismatch effect is manifest in significant correlations between performance on cognitive tests and aided-speech-recognition performance in modulated noise and/or with fast compression release settings. This effect is predicted by the ELU model (Rönnberg et al, 2008). In order to test whether the mismatch effect can be generalized across languages, we examined two sets of aided speech recognition data collected from a Danish population where two cognitive tests, reading span and letter monitoring, had been administered. A reanalysis of all three datasets, including 102 participants, demonstrated the mismatch effect. These findings suggest that the effect of phonological mismatch, as predicted by the ELU model (Rönnberg et al, this issue) and tapped by the reading span test, is a stable phenomenon across these two Scandinavian languages.
High-T c superconducting antenna-coupled microbolometer on silicon (1994)

A process is described for fabricating antenna-coupled resistive-edge microbolometers based on the high-T<SUB>c</SUB> superconductor YBa<SUB>2</SUB>Cu<SUB>3</SUB>O<SUB>7</SUB> (YBCO) on silicon. The YBCO and a buffer layer of yttria-stabilized zirconia (YSZ) were grown epitaxially on silicon to minimize excess electrical noise. A silicon-micromachined YBCO/YSZ air-bridge was incorporated to minimize the thermal conductance and the heat capacity. The thermal conductance of the air-bridge was measured to be 3 X 10<SUP>-6</SUP> W/K at a temperature of 100 K. At an operating temperature of 89 K, the detector is estimated to have a response time of 2 microsecond(s) , a responsivity of the 1000 V/W range, and a noise-equivalent power in the 10<SUP>-12</SUP> W/Hz<SUP>1/2</SUP> range at 1000 Hz.
Estimation of 3D reconstruction errors in a stereo-vision system (2009)

The paper presents an approach for error estimation for the various steps of an automated 3D vision-based reconstruction procedure of manufactured workpieces. The process is based on a priori planning of the task and built around a cognitive intelligent sensory system using so-called Situation Graph Trees (SGT) as a planning tool. Such an automated quality control system requires the coordination of a set of complex processes performing sequentially data acquisition, its quantitative evaluation and the comparison with a reference model (e.g., CAD object model) in order to evaluate quantitatively the object. To ensure efficient quality control, the aim is to be able to state if reconstruction results fulfill tolerance rules or not. Thus, the goal is to evaluate independently the error for each step of the stereo-vision based 3D reconstruction (e.g., for calibration, contour segmentation, matching and reconstruction) and then to estimate the error for the whole system. In this contribution, we analyze particularly the segmentation error due to localization errors for extracted edge points supposed to belong to lines and curves composing the outline of the workpiece under evaluation. The fitting parameters describing these geometric features are used as quality measure to determine confidence intervals and finally to estimate the segmentation errors. These errors are then propagated through the whole reconstruction procedure, enabling to evaluate their effect on the final 3D reconstruction result, specifically on position uncertainties. Lastly, analysis of these error estimates enables to evaluate the quality of the 3D reconstruction, as illustrated by the shown experimental results.
Carbohydrate-Based Polycarbonates. Synthesis, Structure, and Biodegradation Studies (2005)

Linear homo- and co-polycarbonates have been prepared from the sugar-based diols 2,3,4-tri-O-methyl-l-arabinitol and 2,3,4-tri-O-methylxylitol. Statistical co-polycarbonates were obtained from molar feed ratios of sugar:bisphenol A of 1:1 and 2:1. The polycarbonates were stable up to ∼280 °C with maximum decomposition rate above 345 °C. The arabinitol-based homopolymer was found to be semicrystalline whereas the xylitol-based one was amorphous. All the copolymers were amorphous with Tg ranging between 60 and 80 °C. Both homo- and co-polycarbonates showed high resistance to chemical hydrolysis; however, they were enzymatically degraded in different degree. The xylitol-based polycarbonates were the more easily degraded by lipase B from Candida antarctica in acetonitrile at 70 °Cthis enzyme showing a high selectivity toward the configuration of the sugar-based moiety.
ATP-dependent aminophospholipid translocation in erythrocyte vesicles: Stoichiometry of transport (1993)

Vesicles released from human red blood cells by incubation with a suspension of sonicated dimyristoylphosphatidylcholine were purified by gel filtration. Purified vesicles and intact red cells had a very similar composition with respect to phospholipids and integral membrane proteins, but spectrin, the major component of the membrane skeleton, was not found in vesicles. Comparison of red cell and vesicle ATP levels (expressed as micromolar ATP per millimolar hemoglobin) showed a marked difference with a reduced content of only about 30% in vesicles, whatever the initial concentration in the erythrocytes. Spin-labeled aminophospholipids (phosphatidylserine and phosphatidylethanolamine) were translocated to the inner vesicle membrane layer at a comparable rate as in intact red cells provided that vesicles contained enough ATP. The maximum fraction of spin-labeled phospholipids translocated to the inner membrane layer was 84% for phosphatidylserine, 65% for phosphatidylethanolamine, 20-40% for phosphatidylcholine, and below 20% for sphingomyelin. The apparent Km of translocation, expressed as percent of total membrane phospholipid, was 0.14% for spin-labeled phosphatidylserine and 1.19% for spin-labeled phosphatidylethanolamine. This compares well to values established earlier for intact red blood cells. The fact that no ATP was synthesized in vesicles allowed determination of ATP consumption by aminophospholipid transport. The basic ATP hydrolysis rate was increased upon the addition of labeled aminophospholipids but not of labeled phosphatidylcholine or sphingomyelin. The stoichiometry between lipid translocation and ATP consumption, calculated from the respective initial velocities, was 1.13 +/- 0.2 for phosphatidylserine and 1.11 +/- 0.16 for phosphatidylethanolamine.
Importance of Genotypic and Phenotypic Tolerance in the Treatment of Experimental Endocarditis Due to Streptococcus gordonii (1997)

Genotypic and phenotypic tolerance was studied in penicillin treatment of experimental endocarditis due to nontolerant and tolerant Streptococcus gordonii and to their backcross transformants. The organisms were matched for in vitro and in vivo growth rates. Rats with aortic endocarditis were treated for 3 or 5 days, starting 12, 24, or 48 h after inoculation. When started at 12 h, during fast intravegetation growth, 3 days of treatment cured 80% of the nontolerant parent compared with <30% of the tolerant derivative (P < .005). When started at 24 or 48 h and if intravegetation growth had reached a plateau, 3 days of treatment failed against both bacteria. However, a significant difference between the 2 organisms was restored when treatment was extended to 5 days. Thus, genotypic tolerance conferred a survival advantage in both fast- and slow-growing bacteria, demonstrating that the in vitro-defined tolerant phenotype also carried the risk of treatment failure in vivo.
Lipase-Catalyzed Synthesis of Aliphatic Poly(carbonate-<i>co</i>-esters) (2008)

Candida antarctica Lipase B (CALB) was found to catalyze condensation reactions of diethyl carbonate (DEC), diester, and diol to form aliphatic poly(carbonate-co-esters). Poly(butylene carbonate-co-butylene succinate), poly(BC-co-BS), and poly(hexamethylene carbonate-co-hexamethylene adipate), poly(HC-co-HA), with about 1:1 mol/mol ester-to-carbonate repeat units, were prepared by maintaining the diol/diester monomer feed ratio (mol/mol) at 2 to 1. By varying the [DEC] to [1,4-butanediol minus diethyl succinate] ratio from 1:1 to 4:1, poly(BC-co-BS) with terminal groups of up to 96 mol % hydroxyl and 90 mol % ethyl carbonate plus ethyl ester, respectively, were prepared. Weight-average molecular weights (Mw) of poly(BC-co-BS) and poly(HC-co-HA), without product fractionation, reached 26 000 and 59 000 at 80 and 90 °C, respectively. Low polydispersities of poly(HC-co-HA) (Mw/Mn ∼ 1.5) indicate that the polymerization proceeds with chain selectivity. NMR analysis revealed poly(BC-co-BS) copolymers contain carbonate and ester repeat units randomly distributed along polymer chains. CALB-catalyzed reactions between DEC and propyl propionate (PP) gave ethyl propionate (EP), ethyl propyl carbonate (EPC), and dipropyl carbonate (DPC). A reaction pathway to form these products was proposed to involve three equilibrium reactions for which equilibrium constants were determined. Furthermore, CALB-catalyzed carbonate−ester transacylation reactions at 95 °C, for 3 and ≥21 h, between poly(butylene carbonate) (PBC, Mw = 13 800) and poly(butylene succinate) (PBS, Mw = 23 400), gave block copolymers with an average segment length of 2.8 repeat units and random sequences, respectively.
