The Development and Empirical Evaluation of the Korean Smart Distribution Management System (2014)

This paper introduces the development and actual test results of the Korean Smart Distribution Management System (KSDMS). The KSDMS has been designed and developed to cope with the lack of interconnection capability of the Dispersed Energy Resource (DER), to provide standardization and compatibility, and to implement automatic processing of service restoration, in the existing Distribution Automation System (DAS) in Korea. First, real-time system analysis and control application programs were developed, to solve the problems of the existing DAS; and the Distribution Management System (DMS) platform was developed, to run the developed application programs. Second, international standard-based communication, platform, and database structures were adopted, for standardization and compatibility. Third, a platform and application program functions were developed to process faults automatically; and a communication device and an intelligent electronic device (IED) were developed to automate fault restoration, through communication between devices. The KSDMS was evaluated by three tests: unit function test, platform and application program integration test, and empirical test. The first two were conducted on both small and large demonstration systems. The empirical test was performed at the Power Testing Center (PTC) in Gochang, and on a real system, at the Korea Electric Power Corporation (KEPCO), on Jeju Island. The test results verified that the KSDMS can actively resolve the problems of the existing DAS.
Platform-aware dynamic configuration support for efficient text processing on heterogeneous system (2015)

Significant efforts have been made in accelerating computer vision and machine learning algorithms by utilizing parallel processors such as multi-core CPUs and GPUs. Although the suitability of GPU is well-known for computer graphics and image processing applications which require massively parallel floating-point computations, recent research movement towards general purpose computing on-GPU (GPGPU) makes it possible to take advantage of parallel processors to accelerate text processing applications as well. However, how to fully leverage different types of parallel processor architectures to obtain optimal performance (especially with text) without making specific efforts to each platform still remains a great challenge. We applied performance and accuracy enhancements to Naive Bayes algorithm to develop a practically sound implementation of text classification. A platform-aware dynamic configuration support automation flow is also proposed to support the seamless execution of our work across platforms. Experiments on various (integrated graphics, dedicated multiple GPUs) platforms demonstrate that our proposed approach improves both accuracy and performance of text classification.

Structural effects on the nano-scale morphology and conductivity of ionomer blends (2012)

The role of graft and diblock ionomer architecture on the morphology and properties of ionomer/fluoropolymer blends is examined. The graft copolymer consists of a partially fluorinated backbone of P(VDF-co-CTFE) and partially sulfonated polystyrene (PS) side chains while the diblock copolymer consists of a block of P(VDF-co-HFP) and a partially sulfonated PS block. These ionomers are blended with fluoropolymers possessing a chain length that matches the average sequence length of the fluorous block segment of the ionomer. The results from this study are surprising: graft ionomers are primarily insensitive to blending due to the incorporation of the non-ionic fluorous polymers into the domains of the perfluorinated backbone which does not deleteriously affect the interconnecting proton conducting ionic clusters. In contrast, diblock ionomers are highly sensitive to the addition of fluoropolymers and despite the observation that ionic channels are retained, water sorption is decreased due to the increased volume of the non-ionic domains, which decreases proton mobility and proton conductivity.
The factors affecting the survival and prognosis of patients with III~IV gastric cancer: a report of 156 cases (2016)

Objective
To investigate the factors affecting the survival and prognosis of patients with stage Ⅲ~Ⅳgastric cancers.


Methods
A total of 156 cases of Ⅲ~Ⅳ gastric cancer was studied retrospectively from September 1, 2006 to December 31, 2012. Kaplan-Meier analysis, Log-rank univariate analysis, Cox proportional hazards model analysis were used to analyze survival and prognostic factors.


Results
Twelve cases were lost, to the end of the follow-up, 22 cases were alive. The median survival time was 29.3 months. 1-year, 3-year, and 5-year overall survival rates were 83.3%, 37.8%, and 21.2%, respectively. Univariate analysis showed that tumor size, tumor node metastasis (TNM) staging, curative resection, hyperthermic intraperitoneal perfusion chemotherapy (HIPEC), and postoperative chemotherapy were correlated with prognosis (P<0.05 for all). Multivariate analysis showed that TNM staging, curative resection, HIPEC, and postoperative chemotherapy were independent prognostic factors (P<0.01 for all).


Conclusions
TNM staging, curative resection, hyperthermic intraperitoneal perfusion chemotherapy and postoperative chemotherapy are the independent factors affecting the prognosis of stage Ⅲ~Ⅳ gastric cancer after resection. Hyperthermic intraperitoneal perfusion chemotherapy and postoperative chemotherapy can improve their survival.

Liquid–Liquid Phase Separation in Oligomeric Peptide Solutions (2017)

Oligomeric peptides exist widely in living organisms and play a role in a broad range of biological functions. We report the first observation of liquid-liquid phase separation (LLPS) in peptide solutions, in particular, solutions of peptides consisting of noncovalent oligomers. We determined the binary phase boundary of the oligomeric peptide solution and compared the result to the well-established phase diagram of globular proteins. We also provide simple theoretical interpretations of the similarities and differences between the phase diagrams of peptides and proteins. Finally, by tuning inter-oligomer interactions using a crowding agent, we demonstrated that LLPS is a universal phenomenon that can be observed under different solution conditions for a variety of peptides.
True smile recognition system using neural networks (2004)

Recently, research about man-machine interfaces has increased. Therefore application to facial expressions is expected from the development of the man-machine interface. An eigen-face method is popular in these research fields by using the principal component analysis (PCA). But in PCA, it is not easy to compute eigenvectors with a large matrix when considering the cost of calculation to adapt for time-varying processing. In order for PCA to become high-speed, the simple principal component analysis (SPCA) is applied to compress the dimensionality of portions that constitute a face. A value of cos /spl theta/ is calculated using the eigenvector and the gray-scale image vector of each picture pattern. By using neural networks (NN), the value of cos /spl theta/ between true and false (plastic) smiles is clarified and the true smile is discriminated. Finally, in order to show the effectiveness of the proposed face classification method for true or false smile, computer simulations are done.
Bistro: scheduling data-parallel jobs against live production systems (2015)

Data-intensive batch jobs increasingly compete for resources with customer-facing online workloads in modern data centers. Today, the two classes of workloads run on separate infrastructures using different resource managers that pursue different objectives. Batch processing systems strive for coarse-grained throughput whereas online systems must keep the latency of fine-grained end-user requests low. Better resource management would allow both batch and online workloads to share infrastructure, reducing hardware and eliminating the inefficient and error-prone chore of creating and maintaining copies of data. This paper describes Facebook's Bistro, a scheduler that runs data-intensive batch jobs on live, customer-facing production systems without degrading the end-user experience. Bistro employs a novel hierarchical model of data and computational resources. The model enables Bistro to schedule workloads efficiently and adapt rapidly to changing configurations. At Facebook, Bistro is replacing Hadoop and custom-built batch schedulers, allowing batch jobs to share infrastructure with online workloads without harming the performance of either.
Optimized quantum photonics (2020)

Most quantum technologies rely on homogeneous, long lived qubits which are efficiently optically interconnected. To achieve this goal, we have been studying color centers in diamond and silicon carbide, in combination with novel fabrication techniques, and our photonics inverse design approach.
Expression and modulation of IL‐3 and GM‐CSF receptors in human growth factor dependent leukaemic cells (1990)

From the interleukin-3 (IL-3) responsive human myeloid cell line M-07 we derived a subclone, named M-07e, which is fully dependent for growth and survival on either granulocyte-macrophage colony stimulating factor (GM-CSF) or IL-3. In this paper the expression, specificity and modulation of GM-CSF and IL-3 receptors on M-07e cells are described. The specificity of the binding was demonstrated by the failure of other cytokines to compete, at 4 degrees C, with GM-CSF or IL-3 receptors. In addition, IL-3 was found to compete as well as GM-CSF for GM-CSF receptors while GM-CSF was a weak competitor for IL-3 receptors. Quantitative binding studies and Scatchard plot analysis revealed the presence of a single class of high-affinity GM-CSF binding sites (405 +/- 27.4 sites per cell, dissociation constant at the equilibrium 52 +/- 20 pM) and the presence of high and low-affinity regions for IL-3 binding sites (27 +/- 12 and 416 +/- 92 sites per cell for the high and low affinity regions respectively, dissociation constant at the equilibrium, 58 +/- 22 pM and 5.7 +/- 2.0 nM respectively). Finally, in agreement with the hierarchical down-modulation model, we found that IL-3 can down-modulate both IL-3 and GM-CSF receptors while GM-CSF can down-modulate only its own receptors. The present results suggest that M-07e cells, in spite of their neoplastic nature, share, with murine bone marrow cells, similar growth factor receptor regulatory mechanisms. This cell line may be regarded as a candidate model to investigate the physiological events triggered by growth factors binding to human haemopoietic cells.
Measurement of skin-to-kidney distance in children: implications for quantitative renography. (1990)

Variation in skin-to-kidney center distance has been shown to have a significant influence on quantification of renal function with the gamma camera. Several techniques to compensate for this variability have been proposed in adults, yet it has been suggested that depth correction is not necessary for quantitative renography in children. Skin-to-kidney center distances were measured from computed tomograms in 53 supine pediatric patients. Nearly 40% of the kidneys examined varied more than 1 cm from the average renal depth, and 8% deviated more than 2 cm. Right kidney depth differed from left kidney depth by more than 1 cm in less than 10% of the patients. Measurements were in agreement with regression equations based on lateral scintigraphy in children, but were consistently underestimated by nomograms developed for skin-to-kidney center distance in adults. Failure to recognize interindividual variability in skin-to-kidney center distance can introduce significant errors in quantitative pediatric renography.
Fabrication procedures and process sensitivities for CdS/CdTe solar cells (1999)

This paper details the laboratory processes used to fabricate CdS/CdTe solar cells at the National Renewable Energy Laboratory. The basic fabrication technique includes low-pressure chemical vapor deposited SnO2 , chemical-bath deposited CdS, close-spaced sublimated CdTe, solution-CdCl2 treatment, and an acid-contact etch, followed by application of a doped-graphite paste. This paper also describes the results of a reproducibility study in which cells were produced by multiple operators with an average AM1·5 efficiency of 12·6%. And finally, this paper discusses process sensitivities and alternative cell fabrication procedures and reports the fabrication of a cell with an AM1·5 efficiency of 15·4%.

Nuclear magnetic resonance and cryoscopic studies on some alkoxides of titanium, zirconium, and hafnium (1968)

Cryoscopic and n.m.r. studies show that the ethoxide, n-propoxide, and n-butoxide of titanium are trimeric in solution over wide ranges of concentrations and temperature. Intramolecular exchange of terminal and bridging alkoxide groups is too rapid even at –90° to be resolved by n.m.r. at 60 Mc.sec. N.m.r. studies revealed reversible depolymerization of the trimers at high temperatures and low concentrations. Titanium isobutoxide and neopentoxide showed a concentration and temperature dependence of n.m.r. chemical shift due to the presence of monomers, dimers, and trimers. Zirconium and hafnium isopropoxides contain mixtures of trimers and tetramers, but the cryoscopically determined molecular weights are independent of concentration.
Ferulic acid: pharmaceutical functions, preparation and applications in foods (2004)

Abstract Ferulic acid (4‐hydroxy‐3‐methoxycinnamic acid), an effective component of Chinese medicine herbs such as Angelica sinensis, Cimicifuga heracleifolia and Lignsticum chuangxiong , is a ubiquitous phenolic acid in the plant kingdom. It is mainly conjugated with mono‐ and oligosaccharides, polyamines, lipids and polysaccharides and seldom occurs in a free state in plants. Ferulic acid is a phenolic acid of low toxicity; it can be absorbed and easily metabolized in the human body. Ferulic acid has been reported to have many physiological functions, including antioxidant, antimicrobial, anti‐inflammatory, anti‐thrombosis, and anti‐cancer activities. It also protects against coronary disease, lowers cholesterol and increases sperm viability. Because of these properties and its low toxicity, ferulic acid is now widely used in the food and cosmetic industries. It is used as the raw material for the production of vanillin and preservatives, as a cross‐linking agent for the preparation of food gels and edible films, and as an ingredient in sports foods and skin protection agents. Ferulic acid can be prepared by chemical synthesis and through biological transformation. As polysaccharide ferulate is a natural and abundant source of ferulic acid, preparation of ferulic acid from plant cell wall materials will be a prospective pathway.

Error performance of hyybrid space-time block code detected based on sorted QR decomposition (2009)

Error rate performance of the layered spacetime code (LST) combined with Alamouti coding (AC) in flat Rayleigh fading channel is investigated. With the sorted-QR-decomposition-based decision feedback detector (SQRD-DFD), the channel matrix is Q-R decomposed with proper column permutation to minimize the possibility of error propagation. Error rate performance of the LST combined with AC is compared with that of the LST without AC with both sphere detector (SD) and SQRD-DFD. Simulation results show that in full-rank MIMO systems, when AC is introduced into LST, the error rate performance achievable with SQRD-DFD is very close to that obtainable with SD.
Molecular analysis of the IVS8-T splice variant 5T and M470V exon 10 missense polymorphism in Iranian males with congenital bilateral absence of the vas deferens (2006)

Congenital bilateral absence of the vas deferens (CBAVD) is responsible for 2-6% of male infertility in which mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene have been identified. To investigate CBAVD at the molecular level in Iran, we have characterized the mutations in the CFTR gene in 106 patients with this condition. None had clinical manifestations of cystic fibrosis (CF). We also analysed a DNA variant (the 5T allele) in a noncoding region of CFTR, which causes reduced levels of the normal CFTR protein and M470V exon 10 missense polymorphism. Five of the 106 patients with CBAVD had mutations in both copies of the CFTR gene, and none of them had the 5T allele. Eighty-five patients had a mutation in at least one copy of CFTR, and of these patients, 46 had one 5T allele (in 11 cases, two alleles and in 35 cases, just one allele of 5T was detected). In 21 patients, no CFTR and 5T mutations were found (19.81%). 5T/M470 genotype was found in 19 patients, 5T/V470 was found in 3 and 5T with heterozygote form of M470V was found in 24 CBAVD patients. In CBAVD patients, 28 F508del carriers were identified. Most of our patients with CBAVD have mutations in the CFTR gene. The combination of the 5T allele in one copy of the CFTR gene with a CF mutation in the other copy is the most common cause of CBAVD in Iran. The 5T allele mutation has a wide range of clinical presentations and revealed a high frequency, occurring in patients with CBAVD or moderate forms of CF and infertile men.
An Analog/RF Circuit Synthesis and Design Assistant Tool for Analog IP: DATA-IP (2018)

In this paper, an analog circuit synthesis and design assistant tool is proposed. The developed tool employs an SPEA2 algorithm as a multi-objective optimization engine to generate Pareto-optimal Fronts (PoF) for a given design problem. An analog library serving as analog IP, was also constructed, which includes pre-optimized PoFs and extracted PoF models for different loading and power limitation conditions. Thus, the user can either generate a new PoF for her/his problem or use the pre-existing PoFs as well as the extracted models without running any optimization step. The developed tool can also be utilized for feasibility checking of a circuit, performance prediction, and topology selection. The tool gives the opportunity of visualization of the design solutions, by allowing the user to verify the Pareto-optimal points in the test benches, to observe the design specifications of a specific design solution. A graphical user interface (GUI) is developed to combine all these utilities. To demonstrate the developed tool, two different OTA topologies were examined and all parts of the tool were discussed in detail.
Structure and Function in a Bacillus subtilis Sporulation-specific Sigma Factor: Molecular Nature of Mutations in spoIIAC (1987)

The spoIIAC gene was cloned from chromosomal DNA of seven spoIIAC mutants of Bacillus subtilis, and the complete sequence of the gene was determined for each mutant. Three of the mutants proved to have chain-terminating mutations (one of which, previously shown to be suppressible by sup-3, was identified as amber); these led in every case to complete failure either to manufacture spores or to synthesize two enzymes normally associated with stage II of sporulation. The four remaining mutations were missense, and these corresponded to a phenotype in which a few spores are formed and about half the wild-type quantities of the two enzymes are made. Of the four missense mutations, two were near the promoter-distal end of the gene, in a region believed to correspond to the DNA-binding domain of the sigma factor that spoIIAC encodes. The remaining two mutations were in the region of the gene that is thought to correspond to the domain of the protein that interacts with core RNA polymerase.
Collaboration Support for Activity Management in a Personal Cloud Environment (2012)

This paper describes a framework supporting the development of open collaboration environments which integrate heterogeneous business services. The framework facilitates the user cooperation in the execution of shared activities by offering a workspace awareness support which abstracts from the business services employed to operate. The management of the workspaces of the user’s collaborations is based on the functions offered by the Collaborative Task Manager (CTM), which offers a lightweight and flexible model for handling more or less complex collaborations. The CTM is integrated with business services in a loosely coupled way which supports the management of parallel workspaces for accessing the user’s collaboration contexts, their objects and the related awareness information.
A Surface Plasmon Resonance Analysis of the Interaction between the Antibiotic Moenomycin A and Penicillin‐Binding Protein 1b (2002)

The antibiotic moenomycin A inhibits the biosynthesis of peptidoglycan, the main structural polymer of the bacterial cell wall. The inhibition is based on a reversible binding of the antibiotic to one of the substrate binding sites in enzymes such as penicillin-binding protein (PBP) 1b. A novel assay based on surface plasmon resonance (SPR) has been established that can be used to investigate selective binding of the moenomycin sugar moiety and other transglycosylase inhibitors to this enzyme. Suitable ligands were prepared from moenomycin A and coupled to SPR sensor surfaces. Moenomycin analogues with structural variations were used to perform competitive SPR experiments with PBP 1b. The SPR results confirm for the first time that the trisaccharide fragment of moenomycin A (C-E-F-G-H-I) is the minimal structure that possesses all moieties sufficient for biological activity and for affinity towards PBP 1b. The method seems to be appropriate for use in screens for transglycosylase inhibitors that bind to the moenomycin-binding site of the enzyme.
