Speaking Korean In America: An Ethnographic Study Of A Community-Based Korean Heritage Language School

In the United States, often referred to as a nation of immigrants, language diversity has been ironically concealed from public arenas by the displacing ideology of English monolingualism. Minoritized languages have been acknowledged and respected, but they have not been actively promoted and included in mainstream schools. In this context, many immigrant communities have strived to maintain their languages and cultures through community-based heritage language programs. Previous literature has highlighted the challenges these programs face due to inevitable lack of support and resources, as well as the conflicts between immigrant youth and older generations. Through the lens of ethnography of language policy and planning (Hornberger & Johnson, 2007), this study explores the space of a community-based Korean heritage language school in Philadelphia, which I deem as the site of struggle but also the site of promise for immigrant youth. Guided by the notions of communicative repertoires and speech communities (Blommaert & Backus, 2011; Gumperz, 1964), this study explores what linguistic practices teachers and students display, promote, or negotiate in the school, and how these practices construct their own definitions of “speaking and being Korean. ” First, I trace students’ talk about the named codes around them, and discuss how students’ metacommentary reflects their monoglossic imagination of bilingual speakers, and how such imagination might motivate them in learning ‘the Korean language’ yet at the same time discourage them in the process. Then, the study delves into the language ecology of Korean language classrooms in the school, where literacy-focused activities and curricula promote the production of written repertoires of Korean, while creating a gap between the imposed repertoires and students’ existing repertoires. Then, I compare the language policies of two Korean language classrooms and explore the potential of translanguaging pedagogy as a tool for co-learning for both the teacher and students. Community-based heritage language programs may continue to be positioned as marginalized educational spaces in the U.S. context. Nonetheless, this study foregrounds the varied yet converging imaginations of its local actors in constantly pursuing and embracing their ethnic and linguistic heritage and highlights the importance of bringing these voices forward.

ATIVIDADE COLINESTERÁSICA DE ÓLEOS ESSENCIAIS DE PLANTAS MEDICINAIS

The use of medicinal plants in Brazil has been around for a long time, but this handling is not always used properly. Thus, studies in this area have high growth over the years and cover not only the composition of species already used, but also others with potential to be applied in medicinal treatments. The essential oils present in the leaves of aromatic plants are usually extracted by the steam-dragging technique and have in their composition several metabolites such as phenols, terpenes, alkaloids, polyacetylenes, fatty acids, peptides, among others, to which they can be attributed. antioxidant and pharmacological activities. Among these constituents, they have strong inhibitors of the enzyme acetylcholinesterase, and make them effective in the treatment of Alzheimer's disease. They act to slow the hydrolysis of acetylicoline by reducing its levels at nerve endings (where electrical stimulation is generated in the nerves, which is uninterrupted and causing damage to the nervous system) and increasing in synapses that cause high neural stimulation. , this study aims to analyze the efficiency of anticholinesterase activity of essential oils of plant species: Macrosyphonia velame (velame), Lavandula spp. (alfazema brava) e Astronium fraxinifolium (Gonçalo Alves).
Erasmus mobilities and European identity- an exploratory incursion

The Erasmus programme - EU`s flagship student exchange programme – has drawn more and more scholarly attention in the last decades, proportionally with its expansion. In this context, the link between an Erasmus experience abroad and European identity has also been explored by a series of studies. This paper aims to “zoom in” on this matter through a review of the literature that deals with this topic, touching also upon some of the relevant theories and policy documents for the study of this subject matter. To begin with, it will provide some clarifications about the concept(s) of (European) identity, putting them in the context of the Erasmus programme. Further on, it will engage in a mapping exercise of the some of the various approaches that have been taken, the case studies and the research methodologies that have been used or the results that have been observed in the dominant literature on this subject.
Point-cloud detection of buildings based on a latent Dirichlet allocation model with waveform data

ABSTRACT Light detection and ranging are important methods for acquiring digital surface models and can be used to extract building data. Point-cloud detection of buildings is a prerequisite for the model-based expression of buildings. Existing methods are insufficient because of their abstractness of feature extraction and poor accuracy of the detection results. This paper proposes a method for the point-cloud detection of buildings based on a latent Dirichlet allocation (LDA) model with waveform data. This method can extract waveform data via the global convergence Levenberg Marquard algorithm, convert discrete point clouds into point-cluster objects via super voxel segmentation, and detect the point clouds of buildings via the LDA model. Moreover, it supports vector machine classification. Experimental results demonstrate that waveform features and the LDA model both improve the accuracy of building detection. In addition, this method is less susceptible to variations in feature dimensions and is robust in terms of the number of topics and words.
Effect of KCoMoS2 Catalyst Structures on the Catalytic Performance of Higher Alcohols Synthesis via CO Hydrogenation

Different structures of cobalt and potassium modified molybdenum sulfide catalyst (KCoMoS2) were synthesized by hydrothermal synthesis, coprecipitation and reverse microemulsion methods. Nitrogen adsorption, XRD, TEM, XPS and HAADF-STEM-EDS techniques were used to characterize the catalysts structures. The results indicate that the molybdenum sulfide-based catalyst synthesized by the reverse microemulsion method possessed less sheets with small lateral dimensions, while the catalysts prepared by the former two methods contained a higher number of stacking MoS2 layers. In the test of higher alcohol synthesis from CO hydrogenation, it was found that the catalyst synthesized by the reverse microemulsion method exhibited the best CO conversion and C2+OH selectivity among the prepared catalysts. The correlation study between the catalysts structure and the reaction properties implies that the shorter and thinner molybdenum sulfide sheet structure favored for the exposure of the active sites, which, in turn, brought about an enhanced CO conversion and more C2+OH formation.
Modelling crushing crab predation on bivalve prey using finite element analysis

ABSTRACT Amongst the many adaptive features of a bivalve shell, valve shape has been hypothesised to increase structural stability and to aid in withstanding crushing predation. Using Finite Element Analysis we modelled the crushing attack of a crab on a hard clam, soft clam, and blue mussel, assessing the effect of shell shape, size and thickness on their structural performance. Nanoindentation tests provide data on material properties. The hard clam is best suited to distribute applied loads evenly over a thick shell. Blue mussel shells work well when they are thin, and an increase in size is structurally disadvantageous. The soft clam accumulates the highest stresses; change in none of the tested variables improves its performance. The material properties and life habits of these taxa complement the structural responses of their shell shapes to crushing predation. Soft clams are poorly adapted to withstand crushing attacks, avoiding predators by living deeply burrowed in the substrate. Hard clams live shallower in the sediment, relying more on their thick valves to withstand attacks; these organisms are well adapted to disperse loads over a brittle shell. Epifaunal blue mussels absorb more energy than more brittle shells serving the organism well when small and thin.

Melt-rock interaction between granitic pegmatites and hosting amphibolites from the Chiavenna Ophiolitic Unit (Tanno Pegmatitic Field, Central Alps, North Italy)

The Tanno pegmatitic field, placed southward of Chiavenna (Central Alps, Sondrio, Italy), develops a large number of subplanar dykes that crosscut the Chiavenna Unit, an ophiolitic complex mainly composed, in the study area, of amphibolite rocks. This study focuses on the contact between a pegmatitic dyke and the amphibolitic country rock. We distinguished four zones across the contact: I) inner amphibolite, II) contact amphibolite, III) contact pegmatite, IV) inner pegmatite. The inner amphibolite, not affected by melt-rock interaction, is composed of amphibole, phlogopite, ilmenite, titanite and rutile. Two amphibole generations occur, both of them showing a patchy compositional zoning. Amphibole I are Mg-hornblende, whereas Amphibole II have a pargasitic composition. The contact amphibolite shows an enrichment of mica belonging to the phlogopite-biotite series, titanite and the presence of fluorapatite and plagioclase (Ab45-60), that is absent in the inner amphibolite. Close to the contact, amphiboles display no zoning and gain an Mg-horneblenditic composition. The contact pegmatite has quartz, albitic plagioclase, garnet (almandine-spessartine series), muscovite, K-feldspar and fluorapatite. It shows a comb texture, with elongation of plagioclase crystals normal to the contact itself. Far from the contact, the inner pegmatite has an increasing grain-size and a less organized texture. In this zone several accessory phases occur, including gahnite, columbite-(Fe), monazite-(Ce), xenotime-(Y), uraninite and betafite. Whole rock analyses suggest that a chemical exchange, concerning both major elements and trace elements, occurred between the pegmatitic melt and the hosting amphibolite. A considerable increase of SiO2, Na2O and, to a lesser extent, of Al2O3 is observed from the amphibolite towards the pegmatite; K2O and CaO show a decrease at the same extent. The REE pattern in the pegmatite highlights an enrichment in HREE at the contact. Mineral chemistry confirms this trend with variations observable in plagioclase, gradually more albitic from the amphibolite to the pegmatite. Mineralogical characters and geochemical features allow to classify the Tanno pegmatite in the LCT (Lithium, Cesium, Tantalium) family. Based on the metamorphic peak conditions reported from the Lepontine Dome the ambient conditions during pegmatite intrusion were ca. 550°C and 5 kbar. The reduced thermal difference between pegmatite and wall rock explains the diffuse contact observed by X-ray micro-computed tomography. The collected data suggest a chemical interaction between melt and wall rock, according to the following reaction taking place in the amphibolite Amphibole I + Amphibole II + Ilmenite + Pegmatitic melt → Amphibole III + Plagioclase + Phlogopite + Titanite + Fluorapatite
Integration of IoT and chatbot for aquaculture with natural language processing

The development of internet of things (IoT) technology is very fast lately. One sector that can be implemented by IoT technology is the aquaculture sector. One important factor in the success of aquaculture is a good and controlled water quality condition. But the problem for the traditional aquaculture farmers is to monitor and increase the water quality quickly and efficiently. To resolve the above-mentioned problem, this paper proposes a real-time monitoring system for aquaculture and supported with chatbot assistant to facilitate the user. This system was composed of IoT system, cloud system, and chatbot system. The proposed system consists of 7 main modules: smart sensors, smart aeration system, local network system, cloud computing system, client visualization data, chatbot system, and solar powered system. The smart aeration system consists of NodeMCU, relay, and aerator. The smart sensors consist of several sensors such as dissolved oxygen, pH, temperature, and water level sensor. Natural language processing is implemented to build the chatbot system. By combining text mining processing with naive Bayes algorithm, the result shows the very good performance with high precision and recall for each class to monitor the quality of water in aquaculture sector.
Influência da macrogeometria de implantes dentários durante o processo de cicatrização = um estudo clínico, prospectivo, randomizado de boca dividida = The effect of implant macrogeometry on implant stability and biomechanics : a randomized, controlled, split-mouth clinical study

This study assessed the influence of four implant macrogeometries on bone properties and peri-implant health parameters during the healing process. Ninety-nine implants were placed bilaterally in posterior mandibles of 23 patients. Each patient received at least 4 unique dental implant macrogeometries: the standard geometry Integra (IN) and three geometries that induce a ‘healing chamber’: Duo (D), Compact (C) and Infra (IF). The insertion torque (IT) and the implant stability quotient (ISQ) were measured as a proxy for the primary or secondary stability (PS and SS, respectively). In addition, three clinical parameters related to the peri-implant health were monitored: the visible plaque index (VPI), the peri-implant inflammation (PI) and the presence of calculus (CC). The data were collected after 7, 14, 21, 42, 60 and 90 days. The outcome variables were compared using one-way ANOVAs and repeated measures ANOVAs or ANOVA-R followed by the Turkey-Kramer test. The Spearman correlation test was performed to investigate the associations between: i) bone and mechanical characteristics (IT x PS), ii) bone type and type of implant, iii) IT and ISQ for all time intervals. All analyses were considered significant at the 5% level. Macrogeometry did not significantly influence IT and ISQ values. The minimum ISQ was recorded after 7 days (p = 0.0001). An intermediate ISQ was found after 14 days, where the ISQ reached values that are statistically identical to the primary stability. The VPI was influenced by the healing time (p = 0.0001) and by the interaction between time and implant macrogeometry (p = 0.0328), with significantly higher scores for the D and IN implants after 7 days. The PI was only influenced by the healing time (p = 0.0001), and showed a significant decrease from the time of 7 (1.07 ± 0.89) to 21 days (0.18 ± 0.18). A significant positive correlation was observed between IT and total bone height (r = 0.2504; p = 0.0149) and between IT and lingual cortical width (r = 0.2621; p = 0.0107). Conversely, IT and medullary thickness (r = -0.2193, p = 0.0337), total bone width (r = -0.2865; p = 0.0054) and buccal cortical width (r = -0.22227, p = 0.0319) were negatively correlated. The most significant correlation between IT and SS values was recorded by D implants after 90 days (r = 0.5964; p = 0.0027). Within the limitations of this study, it can be concluded that macrogeometry did not influence IT nor ISQ values. Minimum stability was observed after 7 days, and the secondary stability started between 7 and 14 days. The relationship between IT and SS was more evident for the Duo implant, but only in the final stage of healing process (90 days). Key-words: dental implants; macrogeometry, insertion torque, primary stability, secondary stability

A Hot Spot Proof of the Generalized Wall Theorem

Abstract If a sequence of numbers behaves like a random sequence, do we expect subsequences to also behave like a random sequence? Wall proved that normality of a base-b expansion is preserved along arithmetic progressions. What makes arithmetic progressions special is that they are deterministic sequences, a type of low-complexity sequence. We give a self-contained proof that selection along deterministic sequences preserves normality and provide several interesting examples of nontrivial deterministic sequences.
Evaluation of Neuroendocrine Dysfunction in the Acute, Subacute and Chronic Phases of Traumatic Brain Injury

Traumatic Brain Injury (TBI) is a leading cause of premature death and disability worldwide. The greatest challenge associated with endocrine complications in individuals with TBI is early recognition of the subtle problems and in particular at what time after trauma the diagnosis should be made. The plasma testosterone and cortisol concentrations of established mild, moderate and severe TBI Patient were determined especially at the acute, sub-acute, and chronic phases of the TBI. Ninety six male adults without history of chronic ailment were enrolled in the study. In each case, blood was collected within 24h in the first instance, and subsequently at 1st week and 6th week of trauma. The plasma testosterone and cortisol levels were assayed using ELISA. Eighty five of the men with moderate to severe TBI had significantly low mean testosterone level of 3.8nmol/L (1.10ng /ml), moderate to severe TBI had lowered cortisol levels, while those with mild TBI had increased concentration in acute phase, but normal concentrations in the subacute and chronic phases of study. The testosterone and cortisol deficiencies may require replacement to improve recovery and healing from the effects of TBI.

Novel IRE1-dependent proinflammatory signaling controls tumor infiltration by myeloid cells.

Tumor cells are exposed to intrinsic and environmental challenges that trigger endoplasmic reticulum (ER) homeostasis alteration, in turn leading to ER stress. To cope with this, tumor cells engage an adaptive signaling pathway, the unfolded protein response (UPR) thus promoting the acquisition of malignant features. As such, glioblastoma multiforme (GBM), the most aggressive primary brain tumors, exhibit constitutive UPR signals to sustain growth. Herein, we showed that signaling elicited by one of the UPR sensors, IRE1, promotes GBM tumor invasion, angiogenesis and infiltration by macrophages. Hence, high IRE1 activity in tumors predicts worse outcome. We further dissect IRE1-dependent mechanisms that shape the brain tumor immune microenvironment towards myeloid cells. We identify an IRE1-dependent signaling pathway that directly controls the expression/release of proinflammatory chemokines (CXCL2, IL6, IL8) leading to tumor cell-mediated chemoattraction of neutrophils and macrophages. This pathway requires XBP1 non-conventional mRNA splicing and XBP1s-dependent expression of the E2 ubiquitin enzyme UBE2D3. The latter contributes to the degradation of the NF k B inhibitor I k B, leading to the up-regulation of proinflammatory chemokines. Our work identifies a novel IRE1/UBE2D3 proinflammatory signaling axis instrumental to pro-tumoral immune regulation of GBM.
Compact reconfigurable triple‐mode triple‐band substrate integrated waveguide bandpass filter

In this study, a reconfigurable triple‐band triple‐mode substrate integrated waveguide filter is designed and fabricated in the C‐band spectrum. A novel and simplified design procedure based on analytical equations is proposed. The filter design also benefits from a reconfigurable structure, using metallic via holes as perturbation, allowing wide‐band selectivity of the C‐band spectrum (from 4.4 to 6.9 GHz). Moreover, the filter benefits from a magnetic coupling solution between the resonators, which only couples the first three modes and rejects the next resonating modes. Therefore, a large bandgap in the spectrum is achieved. The proposed structure is fabricated and measured, and a high similarity between the simulation and fabrication is observed. The measured results show that the first band can be tuned in the frequency range of 4.4 to 7, the second band can be tuned in the range 5.8 to 7.7 GHz, and the third band from 5.8 to 7.7 GHz. The insertion loss 1.5 to 2.5 dB, 2 to 3 dB, and 2.5 to 3.5 dB for the first, second, and third bands, respectively.
Bigeminus during electroconvulsive therapy resolves spontaneously

Electroconvulsive therapy (ECT) is a frequently used and effective therapy for patients suffering from affective disorders. ECT is known as a relative safe treatment in depressed patients even with pre-existing disorders of the cardiovascular system. However, ECT can induce significant hemodynamic changes, like increases in heart rate and blood pressure as well as cardiac arrhythmias. We describe the occurrence of a non-sustained, spontaneously resolving bigeminus immediately after administrations of ECT in a 62-year-old female patient with an episode of major depression and no specific cardiac history ((German J Psychiatry 2004; 7(3) 45-48).
