A Study on the Color and Visual Image of the Han-River Bridges by Digital Color Measurement (2012)

한강은 서울시의 대표적인 하천이며 서울의 자연경관 및 도시생태, 친환경적 도시경관 유지를 위한 귀중한 경관자원이다. 또한 도시의 이미지와 아이덴티티를 각인 시킬 수 있는 좋은 조건을 가지고 있다. <BR> 도시의 이미지는 색채라는 요소를 통해 시각적으로 영향을 줄 수 있으며, 따라서 한강에 분포되어있는 23개 교량의 색채개선의 필요성이 인식되었다.<BR> 본 연구는 한강의 교량의 색채와 시각적 이미지를 분석하여 주변 환경과 조화로운 색채의 한강교량과, 아이덴티티와 랜드마크적 역할을 할 수 있는 교량의 색채 가이드라인을 정립하는데 있어 그 기초자료가 되고자 하는데 목적이 있다.<BR> 23개의 한강 교량의 주간 색채를 대상으로 하였으며 문헌연구, 현장조사 및 디지털 촬영 등의 다양한 방법을 적절히 활용하여 성공적인 결과 도출을 추진하고자 하였다. 23개의 한강 교량을 범위로 하여 디지털촬영을 통해 L*a*b*값과 먼셀 값을 추출해 내고, 추출한 색채 값을 이용하여 색채분포 분석과 색채 이미지를 분석하였다. 그 결과 난색계열의 색채가 45%로 가장 많이 차지했으며 그밖에도 다양한 색상의 교량이 관찰되었다. 또한, 명도는 중고명도의 범위에서 일정하게 관찰되었지만 채도는 고채도의 자극적인 색채부터 저 채도까지 다양하게 관찰 되었다.<BR> 색채이미지는 동적이며 ‘다양한’, ‘화려한’ 이미지를 나타내고 있었다. 9개소의 교량은 서울시 수변경관색채 가이드라인의 색채범위를 벗어나고 있었으며, 권장 색채이미지와도 차이가 있었다. 수변의 여유로움과 물의 색이 경관의 포인트가 되지 않고 있음을 알 수 있었다. 한강 교량의 색채 선택 시, 교량구조물의 특징, 주변 환경, 지역의 정체성 표현, 원경, 중경, 근경 등을 고려한 색채개선이 필요하다.<BR> 지적된 9개소 중 1개소 교량(방화대교)을 시범교량으로 선정하여 현황과 주변의 색채조사를 통해 주변 환경과 조화로우면서도 가이드라인에 부합될 수 있도록 색채개선안을 제시하였다.<BR> 향후 본 연구를 바탕으로 한, 도시의 정체성과 주변환경을 고려한 체계적인 교량 색채 매뉴얼의 수립을 기대해 본다.
Clonal Population Structure of <i>Pseudomonas stutzeri</i> , a Species with Exceptional Genetic Diversity (2001)

Genetic diversity and genetic relationships among 42 Pseudomonas stutzeri strains belonging to several genomovars and isolated from different sources were investigated in an examination of 20 metabolic enzymes by multilocus enzyme electrophoresis analysis. Forty-two distinct allele profiles were identified, indicating that all multilocus genotypes were represented by a single strain. All 20 loci were exceptionally polymorphic, with an average of 15.9 alleles per locus. To the best of our knowledge, this P. stutzeri sample exhibited the highest mean genetic diversity (H = 0.876) found to date in all bacterial species studied by multilocus enzyme electrophoresis. A high frequency of occurrence of null alleles was identified. The index of association (I(A)) for the P. stutzeri strains analyzed was 1.10. The I(A) values were always significantly different from zero for all subgroups studied, including clinical and environmental isolates and strains classified as genomovar 1. These results suggest that the population structure of P. stutzeri is strongly clonal, indicating that there is no significant level of assortative recombination that might destroy linkage disequilibrium.
The Effect of Nanoparticle Size on <i>In Vivo</i> Pharmacokinetics and Cellular Interaction (2016)

Nanoparticle-based technologies offer exciting new approaches to disease diagnostics and therapeutics. To take advantage of unique properties of nanoscale materials and structures, the size, shape and/or surface chemistry of nanoparticles need to be optimized, allowing their functionalities to be tailored for different biomedical applications. Here we review the effects of nanoparticle size on cellular interaction and in vivo pharmacokinetics, including cellular uptake, biodistribution and circulation half-life of nanoparticles. Important features of nanoparticle probes for molecular imaging and modeling of nanoparticle size effects are also discussed.
Experimental Demonstration of MmWave Vehicle-to-Vehicle Communications Using IEEE 802.11ad (2019)

Millimeter wave (mmWave) vehicle-to-vehicle (V2V) communications has received significant attention as one of the key applications in 5G technology, which is called as Giga-V2V (GiV2V). The ultra-wide band of the GiV2V allows vehicles to transfer gigabit data within a few seconds, which can achieve platooning of autonomous vehicles. The platooning process requires the rich data of a 4K dash-camera and LiDAR sensors for accurate vehicle control. To achieve this, 3GPP, a global organization of standards that provides specifications for the 5G mobile technology, is developing a new standard for GiV2V technology by extending the existing specification for device-to-device (D2D) communication. Meanwhile, in the last decade, the mmWave spectrum has been used in the wireless local area network (WLAN) for indoor devices, such as home appliances, based on the IEEE 802.11ad (also known as Wireless Gigabit Alliance (WiGig)) technology, which supports gigabit wireless connectivity of approximately 10 m distance in the 60-GHz frequency spectrum. The WiGig technology has been commercialized and used for various applications ranging from Internet access points to set-top boxes for televisions. In this study, we investigated the applicability of the WiGig technology to the GiV2V communications through experiments on a real vehicular testbed. To achieve this, we built a testbed using commercial off-the-shelf WiGig devices and performed experiments to measure inter-vehicle connectivity on a campus and on city roads with different permitted vehicle speeds. The experimental results demonstrate that disconnections occurred frequently due to the short radio range and the connectivity varied with the vehicle speed. However, the instantaneous throughput was sufficient to exchange large data between moving vehicles in different road environments.
Recovery of <i>Mycobacterium bovis</i> from Soft Fresh Cheese Originating in Mexico (2006)

Recent outbreaks of human tuberculosis in the United States caused by Mycobacterium bovis have implicated cheese originating in Mexico as a source of these infections. A total of 203 samples of cheese originating in Mexico were cultured, and M. bovis was recovered from one specimen. Therefore, M. bovis can be recovered from cheese and may be a source of human infections.
Who Has Diabetes? Best Estimates of Diabetes Prevalence in the Department of Veterans Affairs Based on Computerized Patient Data (2004)

Development and evaluation of methodology for analyzing computerized patient data can improve the identification of patients with diabetes. The increasing high prevalence of diabetes in VA patients will present challenges for clinicians and health system management.
Effects of vitamin D3 metabolites on cytosolic free calcium in confluent mouse osteoblasts. (1987)

A fluorescent Ca2+ indicator, acetoxymethyl Quin2, was used to quantify changes in the cytosolic free calcium concentration ([Ca2+]i) of confluent mouse osteoblasts. 1,25 - Dihydroxycholecalciferol (1,25 - (OH)2D3, 10-100 pM), 25-hydroxycholecalciferol (25-(OH)D3, 10-100 nM), parathyroid hormone (PTH(1-84), 0.1-10 nM), and prostaglandin E2 (PGE2, 10-1000 nM) all induced immediate (t less than 15 s) transient increases in [Ca2+]i, from a basal level of 135 +/- 8 nM to levels of 179-224 nM. These increases rapidly returned to a plateau approximately 10% higher than the basal level. 24,25-Dihydroxycholecalciferol (24,25-(OH)2D2, 0.1-10 nM) induced a rapid increase in [Ca2+]i which remained elevated for 5 min before decreasing. The 1,25-(OH)2D3- and PTH-induced spikes were abolished by the prior addition of EGTA and Ca2+ entry blockers (verapamil, nifedipine, 1 microM) while the responses to 25-(OH)D3, 24,25-(OH)2D3, and PGE2 were unaffected. Addition of 1,25-(OH)2D3 + EGTA or PTH + EGTA caused enhanced Ca efflux. Addition of drugs which interfere with calcium sequestration by the endoplasmic reticulum (ER) (caffeine, 4 mM; 8-(diethyl-amino)-octyl 3,4,5-trimethoxybenzoate HCl, 0.5 mM) or mitochondria (antimycin, 10 microM; oligomycin, 5 microM) showed that 25-(OH)D3 and PGE2 mainly mobilized Ca2+ from ER. 1,25-(OH)2D3 and bovine PTH caused a transient increase in [Ca2+]i, 70% of which resulted from Ca2+ influx from outside the cells and 30% by release from the ER. The [Ca2+]i increase induced by 24,25-(OH)2D3 included a 30% contribution from the ER and 70% from the mitochondria.
PCSK9 and LDLR degradation (2014)

PCSK9 is an established target for cholesterol-lowering therapies. Further study of PCSK9 regulatory mechanisms may identify additional control points for pharmacological inhibition of PCSK9-mediated LDLR degradation. PCSK9 function could reflect ancient roles in the fasting-feeding cycle and in linking lipoprotein metabolism with innate immunity.
Efficacy of Rifaximin and Vancomycin Combination Therapy in a Patient With Refractory Clostridium difficile–Associated Diarrhea (2007)

Journal of Clinical Gastroenterology: November 2007 - Volume 41 - Issue 10 - p 932-933 doi: 10.1097/01.mcg.0000225685.37465.e7
Diode laser material evaluation using liquid contact luminescence (2002)

Manganese-Based Nanoscale Metal−Organic Frameworks for Magnetic Resonance Imaging (2008)

Manganese-containing nanoscale metal-organic frameworks (NMOFs) with controllable morphologies were synthesized using reverse-phase microemulsion techniques at room temperature and a surfactant-assisted procedure at 120 degrees C with microwave heating. The nanoparticles were characterized using a variety of methods including SEM, TEM, TGA, PXRD, and ICP-MS. Although the nanoparticles gave a modest longitudinal relaxivity (r1) on a per Mn basis, they provided an efficient vehicle for the delivery of large doses of Mn2+ ions which exhibited very high in vitro and in vivo r1 values and afforded excellent MR contrast enhancement. The particle surface was also modified with a silica shell to allow covalent attachment of a cyclic RGD peptide and an organic fluorophore. The cell-targeting molecules on the Mn NMOFs enhanced their delivery to cancer cells to allow for target-specific MR imaging in vitro. The MR contrast enhancement was also demonstrated in vivo using a mouse model. Such core-shell hybrid nanostructures provide an ideal platform for targeted delivery of other imaging and therapeutic agents to diseased tissues.
US e-government headings and their ideology (2014)

The US e-government has continuously maintained a strong interest among researchers from different academic backgrounds. Although interdisciplinary studies have examined a wide range of themes on technology, content, performance and result, the political ideology of web content has been mostly left untouched. This study, therefore, randomly selected 160 US government websites to measure their political representation. However, instead of the extraction of texts from these websites, the first three levels of headings on these websites were surveyed. The results showed: i) significant differences between most variables of different tiers of e-governments; ii) the fact that the sequential major factors are e-services, political education, government performance and transparency. It is argued that the relations between different tiers of governments have been generally reflected in the e-governments, and that all the headings, showing mixed influences from various e-government theories, signify and promote an incontestable ideal of the American Dream in the virtual world.
Order picker routing with product returns and interaction delays (2016)

E-commerce companies often use manual order-picking systems in their warehouses since these systems can provide the required flexibility and scalability. Manual systems have been widely studied, but the operating policies may require significant changes for e-commerce settings. First, to maintain consumers’ loyalty, it is important to maintain delivery reliability even on the busiest days. When the number of order pickers in an area increases, however, more delays due to interactions may occur. For example, travel speed may need to be lowered when order pickers pass each other in narrow aisles. Second, many products sold through e-commerce are returned by consumers. Before these returned products can be sold again, they must be reintegrated in the stock. This paper presents hybrid genetic algorithms to determine routes for simultaneous pickup of products in response to consumers’ orders and delivery of returned products to storage locations. Furthermore, interactions between the order pickers are considered in the routing decisions. The developed algorithms use specific warehouse problem characteristics. We identify the mix of pickups and deliveries to realise the highest savings in practice. It is shown that order-picker interactions can be a significant cause for delay and should be accounted for in the routing.

High Yield Preparation of<i>Lentinus edodes</i>(“Shiitake”) Protoplasts with Regeneration Capacity and Mating Type Stability (1987)

An efficient method for the liberation and regeneration of L. edodes protoplasts was developed using an enzyme mixture of Cellulase Onozuka RS and chitinase, pH 4.6. Homogeneous young mycelia as the protoplast material were quickly cultured in a liquid medium with ‘wood components’ after inoculation of cut fragments of hyphae. The preparation of more than 6 × 107 protoplasts/ml/4 hr and regeneration of more than 15% were attained. The dikaryons formed through the mating of monokaryotic strains of protoplast origin could develop complete fruit bodies on small scale sawdust cultivation (30 g medium) in 50^60 days. After protoplasting or fusion treatment with polyethyleneglycol, the mating phenotypes were sufficiently well preserved.
Dual-beam multiple-wavelength light transmittance measurement for particle sizing in rocket motor plumes (1993)

A multiple-wavelength light transmittance measurement system previously used in a laboratory environment to study particles in solid rocket propellant exhaust plumes was modified for use in the field, where high levels of vibration can degrade the accuracy of data. The system was converted from a single light beam configuration to a dual beam configuration which was capable of obtaining a complete set of 1024 reference and scene measurements in 10.0 ms. Modifications included designing, building and testing a new analog-to-digital data converter trigger circuit, and a rotating-wheel light chopper. Optical components including beam splitters, lenses, and a fiber optic cable were installed, and existing data collection system software was modified. The new system was tested by measuring soot from an oxyacetylene torch to prove the design concept. Test results and system performance were documented. Recommendations for further modifications, improvements and applications are presented.
Management of the patient with subnormal vision (1970)

unique is the fact that three full chapters, in fact, the en¬ tire first half of the book, are devoted to physical optics. The chapters are: Nature and Origin of Light, Photometry—Light Sources—Illumination, and Physical and Chemical Effects of Electromagnetical Radiation. An ophthal¬ mologist wanting to know about these subjects cannot be recommended a bet¬ ter book. The volume has been printed very beautifully in Sweden, though for foreign consumption Butterworth's of London are the publishers. Since good illustrations are an essential part of a book on optics, the publisher must be given due credit. As one interested in modern art I cannot leave the cover design unmentioned. Showing eyes and waves, in color, it is a most up-to-date example of what has become known as op-art, which has begun to revolutionize industrial art. On page 105 the author discusses Donders' so-called reduced eye. The first focal length of this eye is assumed to be 15 mm, the second 20 mm. However, if the radius of curvature of this eye is 5.5 mm, as stated, then its refractive index cannot be 1.33, or vice versa. This small error should be corrected in future editions.

[The relationship between sagittal upper airway size and surrounding skeletal structure with Delaire cephalometric analysis]. (2009)

The sagittal upper airway size of non-snoring males with occlusion is significantly correlated to the craniofacial skeletal structures and head posture,the types of craniofacial growth and the skeletal structure around have remarkable effect on the upper airway space.
Current concepts and diagnostic evaluation of autoimmune disease. (1988)

This article discusses autoimmune reactions and the numerous mechanisms by which an autoimmune response may be initiated, including genetic factors, T-cell bypass mechanisms, and idiotypes. Human autoimmune diseases are classified into three main groups, ie, organ-specific, non-organ specific, and disorders with non-organ-specific autoantibodies with lesions restricted to one or a few organs, that are examined in detail. General laboratory tests and interpretation of results in relation to state or treatment of the particular disease, age and sex of the patient, and the sensitivity of the test system used are reviewed.
EFFECTS OF FIXED RATIO SCHEDULES OF REINFORCEMENT ON EXERCISE BY COLLEGE STUDENTS (2002)

Response-contingent reinforcement was expected to increase the time spent riding a stationary exercise cycle by college women. A single-subject experimental design was used. Three college-age women rode a stationary cycle until they were either too tired to continue or until 45 minutes elapsed. Video clips were used to reinforce cycling in the first part of the experiment. Under some conditions, no video clips were presented (baseline). In other conditions, the video was on for the entire session or 25 sec. of video was presented after the completion of FR 40 (40 rotations of the cycle's pedals) or 80 (80 rotations of the cycle's pedals) schedules. In the second part of the experiment, money was presenred following every 20 (FR 20) or 40 (FR 40) rotations of the cycle's pedals. The time spent riding the cycle increased over the baseline when video clips were presented. No consistent differences were observed when the video clips were on for the entire session and when they were presented under FR 40 and FR 80 schedules. For one out of two participants, monetary reward increased the time spent riding the cycle. The data suggest that reinforcement schedules are a means of initiating and maintaining adherence to an exercise program.
Effects of Processing Variables on Tantalum Nitride by Reactive-Ion-Assisted Magnetron Sputtering Deposition (2006)

The binary compound tantalum nitride (TaN) and ternary compounds tantalum tungsten nitrides (Ta1-xWxNy) exhibit interesting properties such as high melting point, high hardness, and chemical inertness. Such nitrides were deposited on a tungsten carbide (WC) die and silicon wafers by ion-beam-sputter evaporation of the respective metal under nitrogen ion-assisted deposition (IAD). The effects of N2/Ar flux ratio, post annealing, ion-assisted deposition, deposition rate, and W doping in coating processing variables on hardness, load critical scratching, oxidation resistance, stress and surface roughness were investigated. The optimum N2/Ar flux ratios in view of the hardness and critical load of TaN and Ta1-xWxNy films were ranged from 0.9 to 1.0. Doping W into TaN to form Ta1-xWxNy films led significant increases in hardness, critical load, oxidation resistance, and reduced surface roughness. The optimum doping ratio was [W/(W+Ta)]=0.85. From the deposition rate and IAD experiments, the stress in the films is mainly contributed by sputtering atoms. The lower deposition rate at a high N2/Ar flux ratio resulted in a higher compressive stress. A high compressive residual stress accounts for a high hardness. The relatively high compressive stress was attributed primarily to peening by atoms, ions and electrons during film growth, the Ta1-xWxNy films showed excellent hardness and strength against a high temperature, and sticking phenomena can essentially be avoided through their use. Ta1-xWxNy films showed better performance than the TaN film in terms of mechanical properties and oxidation resistance.
Removal of Pedestals and Directional Ambiguity of Optical Anemometer Signals (1974)

Laser Doppler anemometry permits, in principle, the measurement of both magnitude and direction of components of a particle's velocity vector. Most exiting anemometers, however, permit measurements only with a directional ambiguity of 180 degrees , resulting in errors in certain flow fields. Available methods of eliminating the directional ambiguity of Laser Doppler anemometers are reviewed, covering frequency shifting of the incident and scattered light beams, the use of beams with different polarization properties, and employment of multicolor laser beams. The advantages and disadvantages of existing methods are summarized, and suggestions for alterations are made. Different techniques used to remove the pedestal of laser Doppler anemometer signals are also reviewed. Optical techniques should be employed in any advanced optical anemometer system to avoid dynamic range limitations by electronic bandpass filters. Suggestions are made for advanced optical anemometers employing multielement avalanche photodiodes that can be used for simultaneous measurements of two velocity components. These anemometers incorporate devices to sense the direction of the velocity components and to eliminate optically the pedestal of laser Doppler signals.
The motion dynamics of snakes and worms (1988)

Legless figures such as snakes and worms are modelled as mass-spring systems. Muscle contractions are simulated by animating the spring tensions. Directional friction due to the surface structure is included in the dynamic model and legless figure locomotion results. Various modes of locomotion are described.
