Propranolol Hydrochloride Binding in Calcium Alginate Beads (1997)

The interaction of propranolol hydrochloride with alginate molecular chains in calcium alginate beads was investigated. The drug was either incorporated into formed calcium alginate gel beads or incorporated simultaneously with the gelation of alginate beads by Ca2+. Bed produced by the former method had a higher drug content and lower Ca2+ level compared to those prepared by the latter method. The extent of drug binding to the alginate molecules increased with decreasing Ca2+ levels in the beads, indicating that propranolol and Ca2+ shared common binding sites in the alginate chains, me appearance of the beads and the molphology of the alginate polymer in the beads were affected by the amounts of both propranolol and Ca2+ in the beads. Differential scanning calorimetry (DSC) analyses showed that the formation of the calcium alginate gel structure was impeded in the presence of propranolol molecules.

Towards an Enhanced Knowledge-based Decision Support System (DSS) for Integrated Water Resource Management (IWRM) (2014)

Currently, management tools are designed to solve specific water issues, they cannot interoperate and are losing decisional dependencies along the water supply distribution chain. This article reports a DSS, which uses decisional knowledge to improve daily operations. A specially designed Water Management Ontology (WMO) is used to encompass the water cycle from water management perspective and combined with two inference engines which provide recommendations to the water manager. This knowledge characterization permits to semantically represent human and natural paths interactions in order to discover hidden knowledge, hence founding new IWRM strategies to improve resource management and energy efficiency.
Large-Aperture Glass Disk Laser System (1969)

A study of a glass laser designed to operate at extremely high power and radiance for possible use in the production of strong shock waves and high-temperature plasmas is presented. The design makes use of titled face-pumped disks of neodymium-doped glass. The advantages and disadvantages of the four proposed ways to use such a laser are considered. To test the disk concept, a system of five 12.5-cm-diam, 1.25-cm-thick disks was constructed. Design considerations and the results of several measurements with the experimental system are presented. Measurements of the single-pass gain of the five disks showed a gain coefficient of 0.054/cm, which indicates an energy storage of 0.68 J/cm3, or 100 J per disk.

Current and future trends in periodontal tissue engineering and bone regeneration (2021)

Periodontal tissue engineering involves a multi-disciplinary approach towards the regeneration of periodontal ligament, cementum and alveolar bone surrounding teeth, whereas bone regeneration specifically applies to ridge reconstruction in preparation for future implant placement, sinus floor augmentation and regeneration of peri-implant osseous defects. Successful periodontal regeneration is based on verifiable cementogenesis on the root surface, oblique insertion of periodontal ligament fibers and formation of new and vital supporting bone. Ultimately, regenerated periodontal and peri-implant support must be able to interface with surrounding host tissues in an integrated manner, withstand biomechanical forces resulting from mastication, and restore normal function and structure. Current regenerative approaches utilized in everyday clinical practice are mainly guided tissue/bone regeneration-based. Although these approaches have shown positive outcomes for small and medium-sized defects, predictability of clinical outcomes is heavily dependent on the defect morphology and clinical case selection. In many cases, it is still challenging to achieve predictable regenerative outcomes utilizing current approaches. Periodontal tissue engineering and bone regeneration (PTEBR) aims to improve the state of patient care by promoting reconstitution of damaged and lost tissues through the use of growth factors and signaling molecules, scaffolds, cells and gene therapy. The present narrative review discusses key advancements in PTEBR including current and future trends in preclinical and clinical research, as well as the potential for clinical translatability.

Transmission Modulation of a Single-Mode Planar Waveguide by Spectral Hole Burning (1996)

Abstract We investigate persistent spectral hole burning (SHB) in a 120-nm-thick polymer film doped with chlorin molecules superimposed as a cover layer on a commercial single-mode planar glass waveguide. Transmission spectral holes and time-domain picosecond pulse propagation is studied by excitation via the evanescent part of the guided TEO-mode at liquid-helium temperature. We show that single-mode waveguide with SHB cover layer can act as integrated sub-gigahertz narrow-band filter.
Comparison of Optical Frequency Comb and Sapphire Loaded Cavity Microwave Oscillators (2019)

The single-sideband phase noise power spectral density and Allan deviation of a portable microwave oscillator system based on an optical frequency comb stabilized to an ultra-low expansion Fabry-Perot reference cavity is characterized at carrier frequencies of 4.0, 8.0, and 16.0 GHz. Compared to industry standard sapphire loaded cavity oscillators, the photonic microwave oscillator shows superior phase noise at offset frequencies < 100 Hz, and similar performance for offset frequencies from 100 Hz to 100 kHz. At 1-kHz offset, the phase noise power spectral density is better than −140 dBc/Hz at each carrier frequency.

Acne vulgaris is a chronic inflammatory condition of the pilosebaceous units. Antibiotics are widely used in acne therapy and can be administrated topically or systemically. The main negative effect of antibiotic treatment is bacterial resistance to antibiotics.
Monolithic integration of InAs photodiode and GaAs MESFET (1992)

InAs pn diodes were grown in wells pre-etched in GaAs substrates. Despite the large lattice mismatch of 7.2% between GaAs and InAs, good photodiode characteristics were obtained with 77K resistance area products of 70Ωcm2 and a peak detectivity of 1.25 × 10,11cm√(Hz)/W at 2.95μm wavelength. GaAs MESFETs were fabricated next to the embedded detectors, demonstrating for the first time the feasibility of the monolithic integration of InAs photodiodes and GaAs electronic circuits.
Theoretical analysis of dynamic characteristics of piezoceramic polymer composites with 2–2 connectivity (1995)

A dynamic model of piezoceramic polymer composites with 2–2 connectivity is presented. It can be used to evaluate the dispersion curves for the thickness resonance and the stop band edge resonance, the effective velocity of the longitudinal wave, as well as the distributions of strain, stress, and the electric field in a composite. Based on these results, the electromechanical coupling factors are determined using two different methods according to the IEEE recommendation. It is shown that the thickness mode coupling factor kt obtained from the difference of the effective longitudinal velocities at the constant electric field and constant electric displacement is in good agreement with the experimental values. It is also shown that, due to the composite structure, the piezoelectric shear coefficient e15 has a strong effect on both the effective velocity of the longitudinal wave vD and kt even at the limit where the composite thickness is much larger than the period. On the other hand, kt calculated from the energy consideration is much higher than the experimental values and cannot account correctly for the effect of e15 on kt. From the model, the evolution of the thickness mode and the stop band edge resonance with the thickness of a composite and the modes coupling between the two can also be elucidated.
Time optimal movement of cooperating robots (1989)

The maximization of the speed of movement along a prescribed path, of the system formed by a set of robot arms and the object they hold is examined. The actuator torques that maximize the acceleration of the system are shown to be determined by the solution to a standard linear programming problem. The combination of this result with the known control strategy for time optimal movement of a single robot arm yields an algorithm for time optimal movement of multiple robot arms holding the same workpiece.
Abstract 057: Adenosine Kinase Epigenetically Regulates Abdominal Aortic Aneurysm Formation (2018)

Objectives: Abdominal aortic aneurysm (AAA) is a major cause of morbidity and mortality worldwide; however, the molecular mechanisms involved in AAA formation are not well understood. The nucleoside adenosine plays important roles in modulating vascular homeostasis. In this study, we sought to determine whether adenosine kinase (ADK), the adenosine-metabolizing enzyme, modulates AAA formation via control of intracellular adenosine level and investigate the involvement of ADK-mediated epigenetic mechanism in this aortic disease. Methods and results: ADK expression and activity were increased in murine AAA models, including calcium chloride-stimulated AAA and angiotensin II-induced AAA. Using a loss-of-function genetic mouse model, we demonstrated that genetic ADK knockout mice led to increased Intracellular adenosine level in macrophages and vascular cells and developed significantly smaller aortic expansion when subjected to AAA inductions. Notably, knockout of ADK alleviated arterial inflammation and diminished infiltration of macrophages, as well as suppressed arterial extracellular matrix degradation, which was associated with down-regulation of CXCL12, MMP2/9 and adhesion molecule expression. Mechanistically, elevation of intracellular adenosine by genetic inactivation of ADK or exogenous adenosine reduces activation of the transmethylation pathway via inactivation of SAH hydrolase (SAHH) and histone H3K4 methyltransferase (HMT), thus down-regulating expression and signaling of mitogen-activated protein kinases in activated macrophages and vascular cells with pro-inflammatory stimuli. Blocking of the H3K4 transmethylation pathway by knockdown of WDR5, a core subunit of HMT complex, abrogated the beneficial effects of ADK inactivation. Conclusions: Our findings reveal a previously unrecognized role of ADK mediated epigenetic pathways in the pathogenesis of AAA and provides a therapeutic target for the prevention of AAA.
Virgibacillus byunsanensis sp. nov., isolated from a marine solar saltern (2009)

A Gram-variable, motile, endospore-forming and rod-shaped bacterial strain, ISL-24(T), was isolated from a marine solar saltern of the Yellow Sea, Korea, and its taxonomic position was investigated by a polyphasic study. Strain ISL-24(T) grew optimally at pH 7.0-8.0, at 30-37 degrees C and in the presence of 8 % (w/v) NaCl. It contained MK-7 as the predominant menaquinone and anteiso-C(15 : 0) as the predominant fatty acid. The DNA G+C content was 37.6 mol%. A phylogenetic analysis based on 16S rRNA gene sequences showed that strain ISL-24(T) fell within the genus Virgibacillus, clustering with Virgibacillus carmonensis LMG 20964(T) and Virgibacillus necropolis LMG 19488(T), with a bootstrap resampling value of 92.3 %, and exhibiting 97.3 and 97.4 % 16S rRNA gene sequence similarity, respectively, to these strains. Strain ISL-24(T) exhibited 94.8-96.8 % 16S rRNA gene sequence similarity to the type strains of the other Virgibacillus species. Mean DNA-DNA relatedness values between strain ISL-24(T) and V. carmonensis DSM 14868(T) and V. necropolis DSM 14866(T) were 11 and 19 %, respectively. Differential phenotypic properties of strain ISL-24(T), together with the phylogenetic and genetic distinctiveness, revealed that this strain is different from recognized Virgibacillus species. On the basis of phenotypic, phylogenetic and genetic data, strain ISL-24(T) represents a novel species of the genus Virgibacillus, for which the name Virgibacillus byunsanensis sp. nov. is proposed. The type strain is ISL-24(T) (=KCTC 13259(T) =CCUG 56754(T)).
Generalized Descriptor Compression for Storage and Matching (2010)

Smarter phones have made handheld computer vision a reality, but limited bandwidth, storage space and processing power prevent mobile phones from leveraging the full body of existing research. In particular, common techniques which use feature detectors and descriptors to solve problems in image matching and augmented reality cannot be used due to their space and processing requirements. We propose a general descriptor compression method which reduces descriptor size and provides fast descriptor matching without requiring decompression. By demonstrating how to apply our method to the commonly used SIFT, SURF and GLOH descriptors, we show its effectiveness in reducing size and increasing accuracy. In all cases, we reduce the size of the descriptor by an order of magnitude and achieve higher accuracy at a detection rate of 95%.
Log-Gabor Weber descriptor for face recognition (2015)

The Log-Gabor transform, which is suitable for analyzing gradually changing data such as in iris and face images, has been widely used in image processing, pattern recognition, and computer vision. In most cases, only the magnitude or phase information of the Log-Gabor transform is considered. However, the complementary effect taken by combining magnitude and phase information simultaneously for an image-feature extraction problem has not been systematically explored in the existing works. We propose a local image descriptor for face recognition, called Log-Gabor Weber descriptor (LGWD). The novelty of our LGWD is twofold: (1) to fully utilize the information from the magnitude or phase feature of multiscale and orientation Log-Gabor transform, we apply the Weber local binary pattern operator to each transform response. (2) The encoded Log-Gabor magnitude and phase information are fused at the feature level by utilizing kernel canonical correlation analysis strategy, considering that feature level information fusion is effective when the modalities are correlated. Experimental results on the AR, Extended Yale B, and UMIST face databases, compared with those available from recent experiments reported in the literature, show that our descriptor yields a better performance than state-of-the art methods.
연구논문 : 노인복지시설의 지리적 분포현황 분석 -노인복지 생활시설을 중심으로- (2004)

본 연구의 목적은 우리나라 노인복지시설서비스의 공급과 이용의 형평성들 측정하여 노인복지시설 운영의 실상을 형평성 측면에서 올바르게 이해하고 더 나아가 제도개선 및 정책개발을 위한 기초자료를 제공하는데 있다. 이를 위해 지리적 형평성 차원에서 노인복지시설의 정원이 어떻게 배분되어 있으며 입소인원이 어떤 양상으로 분포하고 있는지 통계분석을 통해 검증하였다. 분석 결과에 의하면, 시설종별로 노인인구 1,000명당 정원과 입소인원은 연차적으로 증가하고 있으나 상당한 수준의 지역적 변이(격차)는 계속 존재하고 있다. 또한, 노인인구 1,000명당 정원과 입소인원은 65세 이상의 노인인구의 크기로 대변되는 욕구(need)의 영향을 받는다는 것을 확인하였으며, 시·도간에 존재하는 입소인원 분포의 변이나 지니계수는 계속 감소하고 있지만 아직 개선의 여지가 많은 것으로 평가되었다. 결론적으로, 최근 들어 노인복지시설의 공급과 이용의 형편성이 전반적으로 향상되고 있으나 보다 형평성 있는 제도운영을 위해서는 지역간 불균형이 먼저 해결되어야 한다. 정책 제안으로는 우선 인구고령화 추세에 부응하여 노인복지시설 특히 실비 및 유료시설의 공급이 대폭 확충되어야 함을 지적하였으며, 농어촌 등에 실비/유료시설을 설치하는 경우 지자체에서 재정지원을 할 수 있도록 중앙정부차원에서의 정책적 고려가 필요함을 지적하였다.
Animal models of osteoarthritis in an era of molecular biology. (2002)

Animal models of osteoarthritis (OA) are used to study the pathogenesis of cartilage degeneration and to evaluate potential anti-arthritic drugs for clinical use. In general, these models fall into 2 categories, spontaneous and induced (surgical instability or genetic manipulation). Animal models of naturally occurring OA occur in knee joints of guinea pigs, mice and Syrian hamsters. Commonly utilized surgical instability models include medial meniscal tear in guinea pigs and rats, medial or lateral partial meniscectomy in rabbits, medial partial or total meniscectomy or anterior cruciate transection in dogs. Transgenic models have been developed in mice. These models all have potential use in the study of molecular mechanisms associated with OA development via use of immunohistochemistry, biochemistry and molecular probes to identify altered matrix molecules at different stages in disease progression. Testing of specific types of inhibitors developed through evaluation of matrix changes in the disease process will ultimately help identify key processes which initiate and perpetuate the disease and will lead to discovery of new disease modifying pharmaceutical agents for OA patients. This paper will focus on the discussion of several models which are likely to be useful in the molecular dissection of processes involved in cartilage degeneration.
Tumor-specific and Proliferation-specific Gene Expression Typifies Murine Transgenic B Cell Lymphomagenesis (2006)

The dual bromodomain protein Brd2 is closely related to the basal transcription factor TAF(II)250, which is essential for cyclin A transactivation and mammalian cell cycle progression. In transgenic mice, constitutive lymphoid expression of Brd2 causes a malignancy most similar to human diffuse large B cell lymphoma. We compare the genome-wide transcriptional expression profiles of these lymphomas with those of proliferating and resting normal B cells. Transgenic tumors reproducibly show differential expression of a large number of genes important for cell cycle control and lymphocyte biology; expression patterns are either tumor-specific or proliferation-specific. Several of their human orthologs have been implicated in human lymphomagenesis. Others correlate with human disease survival time. BRD2 is underexpressed in some subtypes of human lymphoma and these subtypes display a number of similarities to the BRD2-mediated murine tumors. We illustrate with a high degree of detail that cancer is more than rampant cellular proliferation, but involves the additional transcriptional mobilization of many genes, some of them poorly characterized, which show a tumor-specific pattern of gene expression.
