한국노부모들의 노후부양관 변화, 1994-2004년 (2005)

노인복지정책이 효과적이고 효율적으로 계획되고 진행되기 위해서는 그 대상이 되는 노인들의 가치관과 태도에 관한 이해가 필수적이다. 그럼에도 불구하고 이를 파악하려는 체계적인 노력과 관심은 부족한 형편이다. 본 연구는 지난 10년간 한국 노인들의 노후부양관이 어떻게 변화해 왔으며, 노인들 내에서 노후부양관의 차이는 어떻게 나타나는지를 파악하려는 목적을 가진다....
Four-element traveling wave photodetector array for high-performance analog fiber-optic links (2002)

We have demonstrated wide-bandwidth photodetector power combining in a structure we call the traveling wave detector array (TWDA). The TWDA embeds several small discrete optical detectors within a microwave quasi-transmission line (QTL) structure that coherently combines their RF photocurrents while maintaining the bandwidth of a single detector.
Intelligent Control of multi-agent system based on multi-objective behavior coordination (2008)

Recently multi-agent systems have been discussed to realize a large size of distributed autonomous system. This paper proposes an intelligent control of multiple partner robots as one of multi-agent systems. First of all, we discuss the current state of researches on the multi-agent systems. Next, to realize a formation behavior, we propose a multi-objective behavior coordination to realize formation behavior based on the integration of the intelligent control from the local viewpoint of individual intelligence and the spring model from the global viewpoint of collective intelligence. Finally, we discuss the effectiveness of the proposed method through several computer simulation results.
The activation of tumoricidal properties in human blood monocytes by muramyl dipeptide requires specific intracellular interaction. (1986)

The purpose of this study was to identify the mechanism by which muramyl dipeptide (MDP) activates antitumor cytotoxic properties in normal and interferon-gamma (IFN-gamma)-primed human peripheral blood monocytes. The structurally and functionally active MDP analog, nor-muramyl dipeptide (nor-MDP), and [3H]nor-MDP were used as reference glycopeptides. Direct activation of normal, noncytotoxic monocytes by nor-MDP was enhanced by its encapsulation within multilamellar vesicles (MLV). Studies with [3H]nor-MDP revealed that the activation of monocytes by nor-MDP was not attributable to its interaction with a specific cell surface receptor, nor did it result merely from the internalization by monocytes of glycopeptide. Subthreshold concentrations of nor-MDP could activate tumor cytotoxic properties in IFN-gamma-primed monocytes. The intracellular interaction of [3H]nor-MDP with IFN-gamma-primed monocytes was specific in that intracellular levels of radiolabeled material could be displaced and recovered as intact molecules by unlabeled nor-MDP, but not by a biologically inactive MDP stereoisomer. Collectively, these results suggest that the activation of tumoricidal properties in human blood monocytes by MDP occurs subsequent to intracellular interaction with specific MDP receptors.
Reduction of Image Noise in Elastography (1993)

Elastography is a method for imaging the elastic properties of compliant tissues which produces gray scale elasticity images called elastograms. The elastograms of phantoms with homogeneous elastic properties exhibit a noisy appearance. We demonstrate that this noisy appearance of the elastograms is due to the nonstationary relationship between the pre- and postcompression signals that results in an artifactual modulation of the strain estimates by the amplitude variations of the envelope of the rf signal. We have identified two methods to reduce the strain modulation artifact. The first method consists of reducing the signal amplitude swings within the observation windows by logarithmically or otherwise compressing the rf signal. The sensitivity of this method to amplitude compression strength and the ability to reduce the noise in the elastograms without affecting the spatial resolution are investigated through simulations. The second method to reduce the strain modulation artifact consists of temporal stretching of the signal obtained after physical compression to approximate the shape of the signal obtained before compression. In this paper, we discuss the first method. The results show that significant improvement in image noise can be obtained with logarithmic amplitude compression. This improvement is obtained in conjunction with improved spatial resolution.
Hydrofluoric Acid Burns (A Case Report ant Review of Literature) (1994)

Hydrofluoric acid, one of the strongest inorganic acid, is used extensively in industry and research. It differs from other acids in that the fluoride ion readily penetrates the skin and causes destruction of deep tissue layers, including bony decalcification. We herein present a case report, suffering from a hydrofluoric acid splashing injury with eye involvement and Ⅱ-Ⅲ degree burn to 15% of the total body surface area. Accurate occupational history taking and physical examination are important to parient assessment. Prompt teratment results in relief of pain and satisfactory outcome, whereas a significant delay in treatment will end up with permanent injury or even death.
Efficient anomaly monitoring over moving object trajectory streams (2009)

Lately there exist increasing demands for online abnormality monitoring over trajectory streams, which are obtained from moving object tracking devices. This problem is challenging due to the requirement of high speed data processing within limited space cost. In this paper, we present a novel framework for monitoring anomalies over continuous trajectory streams. First, we illustrate the importance of distance-based anomaly monitoring over moving object trajectories. Then, we utilize the local continuity characteristics of trajectories to build local clusters upon trajectory streams and monitor anomalies via efficient pruning strategies. Finally, we propose a piecewise metric index structure to reschedule the joining order of local clusters to further reduce the time cost. Our extensive experiments demonstrate the effectiveness and efficiency of our methods.
Tautomeric Forms of Metarhodopsin (1963)

Light isomerizes the chromophore of rhodopsin, 11-cis retinal (formerly retinene), to the all-trans configuration. This introduces a succession of unstable intermediates-pre-lumirhodopsin, lumirhodopsin, metarhodopsin -in which all-trans retinal is still attached to the chromophoric site on opsin. Finally, retinal is hydrolyzed from opsin. The present experiments show that metarhodopsin exists in two tautomeric forms, metarhodopsins I and II, with lambda(max) 478 and 380 mmicro. Metarhodopsin I appears first, then enters into equilibrium with metarhodopsin II. In this equilibrium, the proportion of metarhodopsin II is favored by higher temperature or pH, neutral salts, and glycerol. The change from metarhodopsin I to II involves the binding of a proton by a group with pK 6.4 (imidazole?), and a large increase of entropy. Metarhodopsin II has been confused earlier with the final mixture of all-trans retinal and opsin (lambda(max) 387 mmicro), which it resembles in spectrum. These two products are, however, readily distinguished experimentally.
Using the Optical Mouse Sensor as a Two-Euro Counterfeit Coin Detector (2009)

In this paper, the sensor of an optical mouse is presented as a counterfeit coin detector applied to the two-Euro case. The detection process is based on the short distance image acquisition capabilities of the optical mouse sensor where partial images of the coin under analysis are compared with some partial reference coin images for matching. Results show that, using only the vision sense, the counterfeit acceptance and rejection rates are very similar to those of a trained user and better than those of an untrained user.
Determination of the primary structure of an alpha-amylase inhibitor from wheat kernel by Edman degradation and fast atom bombardment mass spectrometry. (1991)

The primary structure of an alpha-amylase inhibitor (coded 0.39) from wheat kernel was determined by fast atom bombardment mass spectrometry and Edman degradation. The sequence is similar to an extent of 97% compared to the other major component of the monomeric isoinhibitor family coded 0.28. The differences consist of the substitution of a single residue and the deletion of two residues in inhibitor 0.39. Neither heterogeneity nor polymorphism were observed in the primary structures of the inhibitors.
Interacting with an active, integrated environment (1988)

Software engineering environments are intended to provide a cohesive and integrated set of tools to support the process of software engineering with much current research into environment design focussed on maximising the degree to which these tools can be integrated. This paper describes the architecture of a prototype environment which attempts to achieve a high degree of integration using techniques drawn from artificial intelligence, office automation and object-oriented programming. This environment is implemented as a federation of intelligent, co-operating agents which communicate, with each other and with users, by message passing. This paper is particularly concerned with user interface integration including the mechanisms employed to permit inter-agent and agent-user communications.
A Random-Finite-Set Approach to Bayesian SLAM (2011)

This paper proposes an integrated Bayesian frame work for feature-based simultaneous localization and map building (SLAM) in the general case of uncertain feature number and data association. By modeling the measurements and feature map as random finite sets (RFSs), a formulation of the feature-based SLAM problem is presented that jointly estimates the number and location of the features, as well as the vehicle trajectory. More concisely, the joint posterior distribution of the set-valued map and vehicle trajectory is propagated forward in time as measurements arrive, thereby incorporating both data association and feature management into a single recursion. Furthermore, the Bayes optimality of the proposed approach is established. A first-order solution, which is coined as the probability hypothesis density (PHD) SLAM filter, is derived, which jointly propagates the posterior PHD of the map and the posterior distribution of the vehicle trajectory. A Rao-Blackwellized (RB) implementation of the PHD-SLAM filter is proposed based on the Gaussian-mixture PHD filter (for the map) and a particle filter (for the vehicle trajectory). Simulated and experimental results demonstrate the merits of the proposed approach, particularly in situations of high clutter and data association ambiguity.
Influence of Hysteresis on Tensile and Fatigue Failure in Rubbers (1972)

Abstract The failure criterion developed by Harwood et al. between energy input to break and hysteresis at break for amorphous rubbers has been related to the fatigue and cut growth properties of the rubber which are based on the tearing energy theory. It is found that the constant K in the hysteresis failure criterion is a function of the cut growth constant G and the inherent flaw size C 0 . The effect of adding fine particulate fillers to amorphous rubbers on the hysteresis and fatigue properties is considered and shown to be in agreement with the theory.

Therapeutic efficacy of sonic hedgehog protein in experimental diabetic neuropathy (2003)

Hedgehog proteins modulate development and patterning of the embryonic nervous system. As expression of desert hedgehog and the hedgehog receptor, patched-1, persist in the postnatal and adult peripheral nerves, the hedgehog pathway may have a role in maturation and maintenance of the peripheral nervous system in normal and disease states. We measured desert hedgehog expression in the peripheral nerve of maturing diabetic rats and found that diabetes caused a significant reduction in desert hedgehog mRNA. Treating diabetic rats with a sonic hedgehog-IgG fusion protein fully restored motor- and sensory-nerve conduction velocities and maintained the axonal caliber of large myelinated fibers. Diabetes-induced deficits in retrograde transport of nerve growth factor and sciatic-nerve levels of calcitonin gene-related product and neuropeptide Y were also ameliorated by treatment with the sonic hedgehog-IgG fusion protein, as was thermal hypoalgesia in the paw. These studies implicate disruption of normal hedgehog function in the etiology of diabetes-induced peripheral-nerve dysfunction and indicate that delivery of exogenous hedgehog proteins may have therapeutic potential for the treatment of diabetic neuropathy.
Arabidopsis Mutants Lacking Phenolic Sunscreens Exhibit Enhanced Ultraviolet-B Injury and Oxidative Damage (1995)

We have assessed ultraviolet-B (UV-B)-induced injury in wild-type Arabidopsis thaliana and two mutants with altered aromatic secondary product biosynthesis. Arabidopsis mutants defective in the ability to synthesize UV-B-absorbing compounds (flavonoids in transparent testa 5 [tt5] and sinapate esters in ferulic acid hydroxylase 1 [fah1]) are more sensitive to UV-B than is the wild-type Landsberg erecta. Despite its ability to accumulate UV-absorptive flavonoid compounds, the ferulic acid hydroxylase mutant fah1 exhibits more physiological injury (growth inhibition and foliar lesions) than either wild type or tt5. The extreme UV-B sensitivity of fah1 demonstrates the importance of hydroxycinnamate esters as UV-B protectants. Consistent with the whole-plant response, the highest levels of lipid and protein oxidation products were seen in fah1. Ascorbate peroxidase enzyme activity was also increased in the leaves of UV-B-treated plants in a dose- and genotype-dependent manner. These results demonstrate that, in A. thaliana, hydroxycinnamates are more effective UV-B protectants than flavonoids. The data also indicate that A. thaliana responds to UV-B as an oxidative stress, and sunscreen compounds reduce the oxidative damage caused by UV-B.
The Dietary Intake Monitoring System (DIMS): an Innovative Device for Capturing Patient’s Food Choice, Food Intake and Plate Waste in a Hospital Setting (2014)

Portable intelligent devices offer a number of opportunities to collect accurate dietary data for the convenient assessment of food choice and food intake. In this paper we describe a Dietary Intake Monitoring System (DIMS) as a device for capturing accurate data on a patient’s meal both before and after consumption in a hospital setting for the assessment of food choice, food intake and plate waste. The DIMS consists of a digital camera, weighing scale, infrared thermometer, radio-frequency identification (RFID) reader, and a user RFID transponder card. The digital camera and weighing scale captures a digital photograph and measures the weight of content on a patient’s plate before and after consumption. The temperature of food prior to consumption is also recorded with the aid of an infrared thermometer. Based on these inputs the DIMS gives an account of the amount of food on the plate as well as of the serving temperature of it. The DIMS prototype offers new opportunities to improve dietary data collection, routine monitoring of meal temperature and patients nutritional intake in hospital settings.
The role of growth factors in the suppression of active cell death in the prostate: an hypothesis (1994)

Regression of the rat ventral prostate occurs when the level of 5 alpha-dihydrotestosterone, the trophic hormone, drops below the threshold required to suppress apoptosis. The induction of apoptosis in the ventral prostate is accompanied by the increase in the steady-state level of a number of mRNAs coding for proteins that are involved in the latter stages of apoptosis and thus represent secondary thanatogens. These include proteases (cathepsins, plasminogen activators, and collagenase), clusterin, poly(ADP)ribose polymerase, tenascin, and several unidentified genes, as well as several RNases and the classical Ca2+,Mg(2+)-dependent endonuclease. In addition, insulin-like growth-factor-binding protein 5 (IGFBP-5) is induced de novo. We propose that IGFBP-5 may serve to trigger the apoptotic process through the attenuation of the insulin-like growth factor signalling system (which is necessary for cell survival), and as such, represents a primary thanatogen in the prostate.
Evolution of mapmaking: learning, planning, and memory using genetic programming (2002)

An essential component of an intelligent agent is the ability to observe, encode, and use information about its environment. Traditional approaches to genetic programming have focused on evolving functional or reactive programs with only a minimal use of state. This paper presents an approach for investigating the evolution of learning, planning, and memory using genetic programming. The approach uses a multi-phasic fitness environment that enforces the use of memory and allows fairly straightforward comprehension of the evolved representations. An illustrative problem of 'gold' collection is used to demonstrate the usefulness of the approach. The results indicate that the approach can evolve programs that store simple representations of their environments and use these representations to produce simple plans.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A multidimensional phase-locked loop for blind equalization of multi-input multi-output channels (2002)

We present a new technique for blind equalization of multiple-input multiple-output (MIMO) communication channels. In scalar channels it is common to follow a blind equalizer adapted according to the constant-modulus algorithm (CMA) by a phase-locked loop to compensate for carrier frequency offset. We generalize this structure to multiple dimensions, and propose to follow a blind MIMO equalizer adapted according to the vector CMA by a multidimensional phase-locked loop. We show through simulations that the new technique can converge much faster than prior techniques.
A comparison of perceived and real shoulder-surfing risks between alphanumeric and graphical passwords (2006)

Previous research has found graphical passwords to be more memorable than non-dictionary or "strong" alphanumeric passwords. Participants in a prior study expressed concerns that this increase in memorability could also lead to an increased susceptibility of graphical passwords to shoulder-surfing. This appears to be yet another example of the classic trade-off between usability and security for authentication systems. This paper explores whether graphical passwords' increased memorability necessarily leads to risks of shoulder-surfing. To date, there are no studies examining the vulnerability of graphical versus alphanumeric passwords to shoulder-surfing.This paper examines the real and perceived vulnerability to shoulder-surfing of two configurations of a graphical password, Passfaces™[30], compared to non-dictionary and dictionary passwords. A laboratory experiment with 20 participants asked them to try to shoulder surf the two configurations of Passfaces™ (mouse versus keyboard data entry) and strong and weak passwords. Data gathered included the vulnerability of the four authentication system configurations to shoulder-surfing and study participants' perceptions concerning the same vulnerability. An analysis of these data compared the relative vulnerability of each of the four configurations to shoulder-surfing and also compared study participants' real and perceived success in shoulder-surfing each of the configurations. Further analysis examined the relationship between study participants' real and perceived success in shoulder-surfing and determined whether there were significant differences in the vulnerability of the four authentication configurations to shoulder-surfing.Findings indicate that configuring data entry for Passfaces™ through a keyboard is the most effective deterrent to shoulder-surfing in a laboratory setting and the participants' perceptions were consistent with that result. While study participants believed that Passfaces™ with mouse data entry would be most vulnerable to shoulder-surfing attacks, the empirical results found that strong passwords were actually more vulnerable.
Multiple crack weight for solution of multiple interacting cracks by meshless numerical methods (2006)

Abstract We devise a multiple crack weight (MCW) method for the accurate and effective solution of strongly interacting cracks by meshless numerical methods. The MCW method constructs weight functions around cracks so that they simultaneously characterize all the cracks present in the single nodal domain of influence. This approach reduces the number of nodes necessary to achieve sufficient accuracy and consequently it decreases the computational effort. Numerical examples demonstrate that the method allows an accurate solution of multiple cracks problems. Convergence of the method is analysed and discussed. Copyright © 2006 John Wiley & Sons, Ltd.

Signal Demodulation Methods for Electrical Tomography: A Review (2019)

The amplitude and phase of each sinusoidal frequency component in a signal can be obtained by phase-sensitive demodulation, which is commonly used in electrical tomography (ET) and greatly influences the performance of the ET system. In the past decades, many demodulation methods have been developed for the ET system. This paper reviews the latest development in demodulation methods for the ET system, including the traditional methods and several newly proposed methods. To support the standpoints in the review, we implemented these methods in a self-made ECT system and then compared the performances of these methods, including the demands on hardware resources, demodulation time, and accuracy, by simulation and experiments. The main objective of the review is to provide guidance on the selection of appropriate demodulation method for a specific application.
