Respect: Refrainment From Impression Management Behavior Despite High Impression Motivation
We sometimes unintentionally distance ourselves from the people we respect. In a relationship between two individuals of perceived unequal status, what are the behaviors or factors of the person of lower status that distance him or her from the person he or she respects? Impression management is the process by which people control their impressions others form of them (Leary & Kowalski, 1990), and can be a useful theory in explaining this phenomenon; however, it does not explain the entire story. This is one possible instance in which we have high impression motivation but refrain from impression management behavior. This project aims to shed light on the nature and causes of refrainment from impression management behavior despite high impression motivation by exploring the factors that cause people to distance themselves from the people that they respect and perceive to have higher status and power. This research focuses on the distancing factors surrounding the person of the lower status. Data has been collected through one-on-one interviews with people from different backgrounds at different stages of career in diverse organizational contexts
Rethinking gradient weights' influence over saliency map estimation
Class activation map (CAM) helps to formulate saliency maps that aid in
interpreting the deep neural network's prediction. Gradient-based methods are
generally faster than other branches of vision interpretability and independent
of human guidance. The performance of CAM-like studies depends on the governing
model's layer response, and the influences of the gradients. Typical
gradient-oriented CAM studies rely on weighted aggregation for saliency map
estimation by projecting the gradient maps into single weight values, which may
lead to over generalized saliency map. To address this issue, we use a global
guidance map to rectify the weighted aggregation operation during saliency
estimation, where resultant interpretations are comparatively clean er and
instance-specific. We obtain the global guidance map by performing elementwise
multiplication between the feature maps and their corresponding gradient maps.
To validate our study, we compare the proposed study with eight different
saliency visualizers. In addition, we use seven commonly used evaluation
metrics for quantitative comparison. The proposed scheme achieves significant
improvement over the test images from the ImageNet, MS-COCO 14, and PASCAL VOC
2012 datasets
Denoising single images by feature ensemble revisited
Image denoising is still a challenging issue in many computer vision
sub-domains. Recent studies show that significant improvements are made
possible in a supervised setting. However, few challenges, such as spatial
fidelity and cartoon-like smoothing remain unresolved or decisively overlooked.
Our study proposes a simple yet efficient architecture for the denoising
problem that addresses the aforementioned issues. The proposed architecture
revisits the concept of modular concatenation instead of long and deeper
cascaded connections, to recover a cleaner approximation of the given image. We
find that different modules can capture versatile representations, and
concatenated representation creates a richer subspace for low-level image
restoration. The proposed architecture's number of parameters remains smaller
than the number for most of the previous networks and still achieves
significant improvements over the current state-of-the-art networks
Portulaca oleracea Ameliorates Diabetic Vascular Inflammation and Endothelial Dysfunction in db/db Mice
Type 2 diabetes is associated with significantly accelerated rates of micro- and macrovascular complications such as diabetic vascular inflammation and endothelial dysfunction. In the present study, we investigated the protective effect of the aqueous extract of Portulaca oleracea L. (AP), an edible plant used as a folk medicine, on diabetic vascular complications. The db/db mice were treated with AP (300 mg/kg/day, p.o.) for 10 weeks, and AP treatment markedly lowered blood glucose, plasma triglyceride, plasma level of LDL-cholesterol, and systolic blood pressure in diabetic db/db mice. Furthermore, AP significantly increased plasma level of HDL-cholesterol and insulin level. The impairment of ACh- and SNP-induced vascular relaxation of aortic rings were ameliorated by AP treatment in diabetic db/db mice. This study also showed that overexpression of VCAM-1, ICAM-1, E-selectin, MMP-2, and ET-1 were observed in aortic tissues of untreated db/db mice, which were significantly suppressed by treatment with AP. We also found that the insulin immunoreactivity of the pancreatic islets remarkably increased in AP treated db/db mice compared with untreated db/db mice. Taken together, AP suppresses hyperglycemia and diabetic vascular inflammation, and prevents the development of diabetic endothelial dysfunction for the development of diabetes and its vascular complications

A new technique for Nd:YAG laser posterior capsulotomy
AIM: To investigate the effects of a new opening pattern in neodymium:yttrium-aluminum-garnet (Nd:YAG) laser posterior capsulotomy on visual function.METHODS: This technique was conducted along a circular pattern. The energy ranged between 0.8 and 1.2 mJ/pulse was consumed and mean total energy levels were 74±21 mJ (mean±standard deviation:SD, from 40 to 167) and laser shots aimed at 150 µm away behind a datum point and went along an imaginary line which extends 0.5 mm inside from optic margin and into the circular en bloc pattern. Vitreous stands were attached with fragment and then they were cut off by the laser after circular application. The circular fragment was completely separated from vitreous, and then this fragment was quickly sunk in intravitreal space.RESULTS: The follow-up period ranges from at least a week to 40mo, making 15.8mo on average. The procedural outcome showed 96% (74 eyes out of the 77 eyes) enhancement in patients’ visual acuity. Cystoid macular edema or retinal detachment was not observed in any of the patients during follow-up periods.CONCLUSION: This new technique is expected to improve the weaknesses that the conventional procedures have by adding the process to cut off vitreous stands attached with the fragment by the laser to the circular application
Hemorrhagic pericarditis with cardiac tamponade after percutaneous coronary intervention associated with the use of abciximab
Glycoprotein (GP) IIb/IIIa inhibitors, such as abciximab, are used as adjunctive therapy for percutaneous coronary intervention (PCI) in high-risk non-ST-elevation myocardial infarction (NSTEMI) and in ST-elevation myocardial infarction (STEMI), although their effects when used for STEMI are less clear. As the use of GP IIb/IIIa inhibitors becomes more widespread, determining the risks associated with them becomes more important. The major risks associated with the use of GP IIb/IIIa inhibitors are the potential for major bleeding and thrombocytopenia. This is the first reported case in Korea of hemorrhagic pericarditis resulting in cardiac tamponade associated with the use of abciximab, a commonly used GP Ilb/IIa inhibitor, following PCI
Genome shotgun sequencing and development of microsatellite markers for gerbera (Gerbera hybrida H.) by 454 GS-FLX
The objective of this research was to develop and characterize microsatellite markers for gerbera. We used shotgun sequencing with Roche 454 GS-FLX Titanium technology to identify microsatellite loci in gerbera genomic DNA (Gerbera hybrida). The total length of non-redundant sequences obtained was 22,527,019 bp, which consisted of 3,085 contigs and 28,249 singletons. We assembled 61,958 reads into 3,085 contigs, of which 114 (3.70%) contained microsatellite repeats. The average G+C content was 39.3%. Functional annotation to known sequences yielded 14.7% unigenes in the ‘Raon’ cultivar. Analysis of the gerbera genome DNA (‘Raon’) general library showed that sequences of (AT), (AG), (AAG) and (AAT) repeats appeared most often, whereas (AC), (AAC) and (ACC) were the least frequent. Primer pairs were designed for 80 loci. Only eight primer pairs produced reproducible polymorphic bands in the 28 gerbera accessions analyzed. A total of 30 alleles were identified from the eight polymorphic SSR loci, with two to eight alleles per locus (average level of 3.75). These markers will be useful for investigating genetic diversity and differentiation in gerbera. Keywords: Genetic diversity, genomics, microsatellite isolation, pyrosequencing, SSRs.

Tetramethyl-O-scutellarin isolated from peels of immature Shiranuhi fruit exhibits anti-inflammatory effects on LPSinduced RAW264.7 cells
Purpose: To investigate the anti-inflammatory activity of the ethanol extract of the immature fruit of a citrus, Shiranuhi, and to identify the active ingredient.Methods: The immature Shiranuhi peel was extracted with 80 % ethanol, and the extract was fractionated with solvents (n-hexane, ethyl acetate and n-butanol) to afford the corresponding fractions and water residue. Among them, the EtOAc-soluble portion was subjected to medium pressure liquid chromatography (MPLC) over a reversed-phase SiO2 column to give compound 1. The isolated compound was identified based on the proton and carbon nuclear magnetic resonance (NMR) spectra. The release of nitric oxide, prostaglandin (PG)E2, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 secreted by mouse macrophages was measured using RAW264.7 cell culture supernatant.Results: Shiranuhi (Korean name, Hallabong) is an important citrus species cultivated in Jeju Island, Korea. A polymethoxyflavonoid (PMF), tetramethyl-O-scutellarin (1), was isolated from the peels of immature Shiranuhi fruit. Upon the evaluation of anti-inflammatory effects, the flavonoid 1 decreased the nitric oxide production in macrophage cells with high efficiency, viz, 50 % inhibition concentration, IC50 of 57.4 μM. Subsequent studies demonstrated that PMF 1 effectively inhibited the generation of PGE2, TNF-α, IL-1β, and IL-6 cytokine in a dose-dependent manner.Conclusion: Tetramethyl-O-scutellarin (1) has been successfully isolated from Shiranuhi species for the first time. Thus, Shiranuhi fruit peel extract containing PMF 1 can potentially be applied as an antiinflammatory ingredient in food or cosmetic industries.Keywords: Shiranuhi fruit, Nitric oxide, Tetramethyl-O-scutellarin, Anti-inflammator
A DNA barcode library of the beetle reference collection (Insecta: Coleoptera) in the National Science Museum, Korea
AbstractColeoptera is a group of insects that are most diverse among insect resources. Although used as indicator species and applied in developing new drugs, it is difficult to identify them quickly. Since the development of a method using mitochondrial DNA information for identification, studies have been conducted in Korea to swiftly and accurately identify species. The National Science Museum of Korea (NSMK) has been collecting and morphologically identifying domestic reference insects since 2013, and building a database of DNA barcodes with digital images. The NSMK completed construction of a database of digital images and DNA barcodes of 60 beetle species in the Korean National Research Information System. A total of 179 specimens and 60 species were used for the analysis, and the averages of intraspecific and interspecific variations were 0.70±0.45% and 26.34±6.01%, respectively, with variation rates ranging from 0% to 1.45% and 9.83% to 56.23%, respectively
