Published: February 2022

Abstract. Yobele AB, Kilasara M. 2021. Interaction of soil-inorganic nitrogen in rice fields of Kilombero Floodplain, Tanzania. Intl J Bonorowo Wetlands 11: 32-47. At Ifakara Morogoro Region, a study was done to determine the effect of selected crop management interventions and hydrological conditions on soil NH4+ and NO3- concentration. The study chose Valley Middle and Fringe locations as distinct hydrological zones. Three repetitions of an experiment with six treatments were laid down: semi-natural vegetation (TR1), farmers practice (TR2), bunding alone (TR3), bunding + 60 kgN/ha (TR4), bunding + 120 kgN/ha (TR5), and bunding+Lablab green manure (TR6). As a test crop, the SARO 5 rice variety was employed. The trials took place during the pre-season of 2014/15 and the regular 2015/16. Data were gathered from a depth of 0-10 cm in the soil. Using the GenStat Program, two-way ANOVA and post hoc-Tukey HD test statistical analyses were done. Pre-season NH4+ concentrations followed three distinct patterns: an initial increase to peak levels within 3 and 6 weeks for the Fringe and Middle sites, a fall (7th to 9th week for the Middle, and 4th to 6th week for the Fringe), and an increase (from 7th, Fringe and 10th week, Middle). The Middle site had the highest peak NH4+ levels (TR6-0.007401, TR5-0.004776, and TR4-0.04525, g/kg soil, and TR4-0.004524, TR5-0.004595, g/kg soil, respectively). At the Middle and Fringe locations, peak NH4+ values varied considerably between treatments, following the trend TR6>TR5>TR3>TR4>TR1>TR2 and TR4>R6=TR5=TR3+TR2>TR1. Nitrate levels declined within 1-2 weeks at both sites, reaching their lowest levels between 4 and 7 weeks, and then gradually increased to 10. Rice cropping season NH4+ and NO3- variation followed a similar pattern for both locations, except a sharp increase in treatments with N input during weeks 8 and 10. Hydrological conditions had no significant effect on the NH4+ and NO3- levels (P = 0.05). The study advises that the experiment be repeated under controlled conditions.

Published: February 2022

Purpose of the article: The objective of this research was to examine the helpfulness of new IT tools which are used to project management. IT tools have been an important part of project management for a long time but after the pandemic time became an absolute necessity. The authors of this research examined whether project managers dealing with big international projects based on soft skills with the necessity of quick communication with internal and external stakeholders are convinced to work with a new tool and find it helpful.Methodology/methods: As a research sample, four consortiums of Interreg Central Europe have been chosen. Each consortium consists of 10 to 12 participant institutions, including the institutions of higher educations, NGOs and municipalities. The main objective of all selected projects is to support groups of migrants and refugees from programme countries. For the purpose of the research, the survey was designed and submitted to all institutions and project managers involved in four chosen projects.Scientific aim: The aim of the paper was to identify the issues regarding project management and risk management before and during the COVID-19 pandemic within Interreg Central Europe programmes considering internal and external stakeholders of the four chosen projects.Findings: The study showed that owing to the use of new IT tools, it was possible to maintain and improve communication in international project teams during the pandemic. The study also showed that surveyed project managers find helpful to work with new IT tools; however, they recognize risks related to communication with external project stakeholders. Most of those surveyed stated that new IT tool boosted the project teams’ communication but did not affect communication with digitally excluded stakeholders.Conclusions: In the authors’ opinion, the results confirm the purposefulness of using and developing the new IT tools despite issues with reaching external stakeholders. In the next step, the research will focus more on the external stakeholders’ issues with access to digital technologies, especially IT tools themselves.

Published: February 2022

Quantitative phase imaging (QPI) is an ideal method to non-invasively monitor cell populations and provide label-free imaging and analysis. QPI offers enhanced sample characterization and cell counting compared to conventional label-free techniques. We demonstrate this in the current study through a comparison of cell counting data from digital phase contrast (DPC) imaging and from QPI using a system based on Fourier ptychographic microscopy (FPM). Our FPM system offers multi-well, parallel imaging and a QPI-specific cell segmentation method to establish automated and reliable cell counting. Three cell types were studied and FPM showed improvement in the ability to resolve fine details and thin cells, despite limitations of the FPM system incurred by imaging artifacts. Relative to manually counted fluorescence ground-truth, cell counting results after automated segmentation showed improved accuracy with QPI over DPC.

Published: February 2022

Broadband second-harmonic-generation (SHG) in GdCOB crystals was demonstrated for the first time. Theoretical calculation and experiments for the type-I frequency doubling of GdCOB crystal was performed. The result revealed that the spectral retracing point of phase-matching angle was at around 1.65 µm. For broadband fundamental laser source tuning in the range of 1.55-1.7 µm, efficient SHG was realized, the highest conversion efficiency was 56%, and the output bandwidth reached 16 nm.
Intra-cavity dark pulse generation through synchronized sum-frequency mixing

Published: February 2022

A Nd:YVO4 laser operating at 1064 nm generating a stable mode-locked train of 10 ps-long dark pulses with a 211 MHz repetition rate is presented. The mode-locking relies on a periodic loss modulation produced by intra-cavity sum-frequency mixing with a synchronous bright-pulse train from a mode-locked femtosecond Yb:KYW laser at 1040 nm. A modulation depth of 90% was achieved for the dark pulses, confirmed by cross-correlation measurements. The ultrafast loss modulation injects power into the Nd:YVO4 laser cavity modes beyond the laser gain bandwidth. At proper laser cavity length, the detuning interaction of these modes with the lasing modes leads to the generation of periodic ultrafast transients at frequencies above 1.5 THz.
Markovian analysis of unreliable multi-machine flexible manufacturing cell
Authors: Hamasha Mohammad , Hamasha Sa’d , Aqlan Faisal , Almeanazel Osama
Published: February 2022

In this paper, a Markovian model is constructed to test a flexible manufacturing cell’s (FMC) performance. The considered FMC includes a conveyer belt, robot, and n machines. The conveyer belt delivers the working part to the robot, and the robot picks it up and loads it onto the machines. The movement of a working part from one step to the next depends on the availability of the tool in the next step (i.e., conveyer belt, robot, and machine). Any machine is assumed to potentially fail during the processing time as a result of high loading stresses. First, a Markovian model is constructed for single-machine and double-machine FMCs. Then, a generalized FMC with an n-machine is constructed. The introduced model is illustrated with two numerical examples for both the single- and triple-machine. The Markov chain model can be used to estimate the FMC performance measures (i.e., overall utilization of machines and production rate). It is used to analyze the response of these measures under varying parameters (i.e., conveyor belt delivery rate, robot loading rate, processing rate of a machine, failure rate of a machine, and down machines’ repairing rate). Moreover, an economic model based on the Markov chain model is introduced to analyze the FMC’s net profit under these varying parameters.

Aim

To investigate the characteristics of coronary artery bifurcation type (parallel or perpendicular type) using three-dimensional (3D) optical coherence tomography (OCT), and determine the feasibility, reproducibility, assessment time and correlation with bifurcation angles measured by 3D quantitative coronary angiography (QCA).

Methods and results

We evaluated 60 lesions at the coronary bifurcation that were treated by main vessel (MV) stenting with kissing balloon inflation (KBI) under OCT/optical frequency domain imaging (OFDI) guidance. Inter- and intra-observer agreement regarding the assessment of 3D bifurcation types were 0.88 and 0.94, respectively. The assessment times of 3D-OCT bifurcation type with OCT and OFDI were within about 30 seconds. 3D-OCT bifurcation types showed the greatest correlation with the distal bifurcation angle assessed by 3D-QCA among the three bifurcation angles (distal bifurcation angle, proximal bifurcation angle and main vessel angle), and the optimal cut-off distal bifurcation angle to predict a perpendicular type bifurcation, as determined by ROC analysis, was 51.0° (AUC 0.773, sensitivity 0.80, specificity 0.67). Based on this cut-off value for the distal bifurcation angle (51°), the diagnostic accuracy for perpendicular type bifurcation in cases with a BA ≥ 51° (n = 34) was 70.6% (24/34) and that of the parallel type bifurcation in cases of BA < 51° (n = 26) was 76.9% (20/26).

Conclusion

Performing 3D-OCT for assessment of coronary artery bifurcation type is feasible and simple, and can be done in a short time with high reproducibility.

A tátongó mélységként megjelenített dantei Poklot, amely egy lény óriási szájához hasonlóan elnyeli a holtak lelkeit, a legkülönbözőbb szörnylények népesítik be. Jelen tanulmány Geryon színjátékbeli szimbolikájára és szerepére fókuszál, célja ezenkívül a Dante gondolkodásmódját meghatározó antik és középkori források, valamint a dantei inventiók bemutatása. A költő rendkívül tudatosan alkotta meg a hamisság, a csalás tökéletes figuráját olyan komponensekből, amelyek részben a pogány hagyományból erednek, részben korának bestiáriumaiban, az enciklopédiákban leírt tulajdonságaik, valamint azon jelentések révén, amelyeket a bibliai exegézis kapcsolt azokhoz. Geryont, a legapróbb részletekig kidolgozott démoni teremtményt a jegyek sokfélesége jellemzi: arca becsületes emberarc, jóságos, bizalmat keltő arcán kívül azonban minden más testrésze, amely állat elemekből áll, a hamissághoz, a hazugsághoz köthető.
Nyaralás alatti munkavégzés: a workcation turizmus elméleti és gyakorlati kérdései
Authors: Pécsek Brigitta
Published: February 2022

Munka, szabadidő és alvás a három fő tevékenység, melyek ciklikus váltakozásai mentén éli életét a modern ember. A három alaptevékenység a múltban egyértelműen elkülönült egymástól. A határok elmosódása a későmodernitás trendje, melynek következményeképpen napjainkban két, egymással ellentétes, utazási forma terjedésének lehetünk tanúi: a staycation (turizmus az otthon elhagyása nélkül) és a workcation (nyaralás alatti munkavégzés). A tanulmány ez utóbbi jelenséget vizsgálja meg elméleti és gyakorlati oldalról: a szerző először egy saját workcation koncepciót fogalmaz meg, majd a szakirodalom és az online kérdőíves megkérdezés elemzésének eredményeként hat különböző workcation turista típust különít el és jellemez. Ezek alapján meghatározza azt a szegmenst, mely igények figyelembevételével egy adott település fenntartható turisztikai fejlesztéseket vihet végbe. A szerző zárásként egy külföldi példát is bemutat, ahol ezek a fejlesztések már megvalósultak, és sikeresen működnek.
Felelős turizmus, felelős döntéshozók, avagy CSR, ahogy a balatoni turizmusban érintett szereplők látják
Authors: Hajmásy Gyöngyi
Published: February 2022

A klímaváltozásnak, valamint az egyre inkább kimerülőben levő természeti erőforrásoknak köszönhetően növekvő trendet mutat mind a társadalmilag, környezetileg és gazdaságilag felelős turisztikai termékek terjedése, mind az irántuk mutatkozó kereslet. Mivel a turizmus erőteljesen a desztinációk természeti vonzerején alapszik, a környezetvédelem és a környezet megőrzése kiemelten fontos. Ugyanakkor a tu­risztikai vállalkozások felelősek az adott közösségért is, amelyben működnek. Ennek jegyében megfelelően kell kezelniük a turizmus természeti környezetre, valamint közösségre gyakorolt hatását. Ez a tanulmány a Balaton régió turizmusában érintett szereplők aktuális CSR-ral kapcsolatos nézőpontját vizsgálja.
Decolonising design practices and research in unceded Australia: reframing design-led research methods
Authors: Gothe Jacqueline , Donnellan Caroline , De Santolo Jason
Published: February 2022

Much of design teaching, learning and research in Australia is determined by Eurocentric traditions and the ongoing colonial project. In this context Indigenous Peoples continue to experience erasure, silencing and appropriation of practices and knowledges. The Visual Communication Design Program, situated in the School of Design at the University of Technology Sydney (UTS), is committed to disrupting this trajectory. In this article we describe an immersive model that seeks to challenge the role of the design educator, creative practitioner and researcher on unceded Gadigal Lands in the city of Sydney, Australia. We reflect on the challenges of facilitating Visual Communication Design and Emergent Practices, for a third iteration as an online studio experience, during COVID-19 in the context of the climate crisis, bushfires and Black Lives Matter. This iteration is the result of four years of deep collaboration with local First Nation Elders, Indigenous scholars and practitioners. The research-focused studio for 180 final-year visual communication design students is led by Local Elders, cultural and research advisers with the support of studio leaders. The consideration of design-led research methods through a process that infuses Indigenous research principles builds on the longitudinal research into the role of the emplaced designer in Indigenous-led projects on Country. Our studio, titled ‘In Our Own Backyard’, provides students with strength-based design capabilities and understandings of the principles of the United Nations Declaration of Indigenous Peoples Rights (UNDRIP), Indigenous Cultural and Intellectual Property Rights (ICIP) and the Australian Indigenous Design Charter. As a studio experience, the aim is to create conditions which spark possibilities for re-orientation towards relational and respectful negotiation of difference, and the capacity to action Indigenous self-determination in complex practitioner scenarios.
La tradición mística en Sampaio Bruno
Authors: Lázaro Pulido Manuel
Published: February 2022

Sampaio Bruno (1857-1915) es uno de los autores culturales más significativos de Oporto y de todo Portugal. Su pensamiento filosófico-religioso se inscribe en el marco de un romanticismo tardío que se expresa de forma especial en su concepción mística. La mística de Sampaio Bruno expresa su romanticismo en la lectura ecléctica, antimetafísica y gnóstica de la tradición filosófica, que sin embargo confirma la riqueza de esa tradición en la búsqueda del infinito.

Published: February 2022

Este estudio tiene como objetivo comparar el conocimiento socioemocional en dos grupos de niños que pertenecen a entornos socioculturales muy diferentes y evaluar el impacto de una intervención dialógica en la mejora de estas competencias. Se seleccionó una muestra de 103 niños de 4 y 5 años de edad (61 caucásicos y 42 de etnia gitana) que se dividieron en grupo control (N = 49) y experimental (N = 54). Los niños fueron evaluados en conocimiento emocional, conocimiento de estrategias de interacción social y lenguaje antes y después de la intervención. Los profesores de los centros escolares realizaron una intervención dentro del aula basada en el diálogo. Los resultados muestran importantes diferencias previas entre ambos grupos y mejoras significativas tras la intervención en aspectos diferenciados. El diálogo sobre cuestiones emocionales se perfila como una herramienta útil que desde el entorno escolar puede ayudar a compensar las desigualdades que los entornos desfavorecidos provocan en el desarrollo emocional de los niños.
Personification in EFL learners’ academic writing: A cognitive linguistic stance
Authors: Belkhir Sadia
Published: February 2022

The paper offers a report of a small-scale corpus investigation into some advanced EFL learners’ use of personification in academic writing within a higher education context (Mouloud Mammeri University). Its main objective is to shed light on the extent of the occurrence of this phenomenon in their writings. The question raised is whether the examination of their dissertations would reveal extensive use of personification. Conceptual Metaphor Theory constitutes the theoretical framework featuring in this research. Relying on the Metaphor Identification Procedure (MIP) (Pragglejaz Group 2007), six master’s dissertations are selected for examination, and a quantitative analysis of the identified metaphorically used words is conducted. The results of the study reveal an overwhelming manifestation of personification. These findings may constitute a small contribution to the field of education, as offering useful data to educational practitioners and researchers.
Zur Entwicklung der kodematischen Theorie des Fremdsprachenunterrichts
Authors: Szczodrowski Marian
Published: February 2022

The discussion addresses the linguistic code and its contribution to the development of the codematic theory of foreign-language teaching. This theory deals with the essence and properties of the course of processes of coding and decoding foreign-language structures. Teachers and learners participate in these processes as primary and secondary senders and receivers of transmitted lexical-grammatical structures with the aim of learners’ mastering them. The process of learning and mastering foreign-language structures takes place in two stages, that is, during their decoding and construction in the form of structural matrices in the receiver’s appropriate memory. In this way, in the receiver (learner) there forms a warehousing mechanism with regard to the foreign language. This mechanism is equipped with a receptive and (re)productive functioning force, that is a force that activates the structural matrices. Structural matrices in long-term memory attain the appropriate force of activation, and therefore demand constantly being brought up to date in various syntagmatic-syntactic constructions, that is in the process of their encoding.
A socially anchored approach to spatial language in Kalaallisut
Authors: McMahan Hilary , Grenoble Lenore A. , Petrussen Alliaq Kleist
Published: February 2022

In this article we demonstrate the fundamental relationship between the linguistic encoding of spatial relations and the topography of Greenland as an island, more specifically as a large island with considerable inland ice, and social engagement with that space. Kalaallisut (or Greenlandic, ISO 639-3 kal) uses an absolute frame of reference and a cardinal direction system that arises from an environmentally anchored coastal orientation system. Sociocultural knowledge and experiences play an important role in this system. It is deeply rooted in the geophysical environment, and changes to that environment can and do affect the linguistic encoding of space. Crucially, changes in people’s relationship with the environment affect how it is conceptualized in language. This is part of a broader pattern of Inuit language usage in changing Arctic environments and societies.
Directionals, topography, and cultural construals of landscape in Lamaholot
Authors: Nagaya Naonori
Published: February 2022

This paper investigates “directionals” or geocentric spatial terms in Lamaholot, examining the interaction between directionals, topographic environment, and cultural construals of landscape. Lamaholot is an Austronesian language of eastern Indonesia spoken on the volcanic island of Flores. The Lewotobi dialect, with which this paper is concerned, is spoken on the coastal area between Mt. Lewotobi and the Solor Sea. Reflective of this topographic environment, this language has “directionals” or grammatical terms defined with respect to landmarks:rae‘mountainward’,lau‘seaward’,wəli‘parallel with the coast’,teti‘upward’, andlali‘downward’. After describing how the spatial orientation represented by directionals is embedded in linguistic and sociocultural practices in Lamaholot-speaking communities, this paper shows that directionals exhibit intriguing diversity in interpretation and morphosyntax: they constitute a coordinate system for geocentric frame of reference, refer to different directions depending on different construals of landscape, and can appear in various syntactic positions. It is argued that this diversity can be understood in terms of a complex interplay of topographic environment, sociocultural practices, language uses, and linguistic repertoire, as assumed in the Sociotopographic Model (Palmer, Bill, Jonathon Lum, Jonathan Schlossberg & Alice Gaby. 2017. How does the environment shape spatial language? Evidence for sociotopography.Linguistic Typology21(3). 457–491). Thus, the directional system in Lamaholot makes a strong case for a sociotopographic approach to spatial language.
The irrelevance of scale and fixedness in landscape terms in two Australian languages
Authors: Hill Clair
Published: February 2022

This article examines how the speakers of Manyjilyjarra (Great Sandy Desert) and Umpila/Kuuku Ya’u (Cape York Peninsula) linguistically categorize the landscape in which they live. Located on opposite sides of Australia, in highly contrasting arid inland and tropical coastal environments, the semantics of the landscape feature terminology in these two Australian languages have key similarities. Both lexical sets overwhelmingly classify the landscape with the use of abstract and general concepts of shape and material make-up. Together with a lack of specification of size or fixedness in this terminology, this presents intriguing issues for received conceptualizations of landscape in the geosciences and language sciences. This article finds that complex and recurrent interests in material make-up extend beyond landscape feature terminology in both languages and reveal possible cultural priorities underlying the semantic patterns.
Recognition and enforcement of foreign judgments in American courts and the limits of the law market model
Authors: Solimine Michael E.
Published: February 2022

The law market model posits that the most appropriate resolution of choice-of-law disputes in private international law is to permit individuals to choose ex ante the law that applies to them. This is contrasted to the public law model where courts choose law based on the perceived interests of, or the parties’ connections with, the states or nations involved. The law market model envisions that consumer choice will lead to optimal competition among jurisdictions to supply the most efficient law. This model has influenced the rise of party autonomy, most notably in the widespread enforcement of many contractual choice-of-law and forum-selection clauses. One area that the model has had little influence on is the enforcement of foreign judgments. In the United States, judgments from other countries face higher hurdles in obtaining recognition and enforcement, as compared to judgments issued by courts of sister states. There has been little discussion in the law market literature of the possibility of ex ante contractually waiving these hurdles, or of choosing the law of states that make it easier to enforce foreign judgments. This reticence appears to be based in part on the assumption that state law on such recognition is mandatory and non-waivable, and that such law reflects the sovereign interests of states. Revisiting this regime through the lens of the law market model suggests that courts and public policymakers should permit parties, within broad limits, to contractually waive or select the law on judgment recognition, as they are permitted to do with other areas of law.
An Anthropocene Viewing Condition
Authors: Peterson Jennifer Lynn
Published: February 2022

This essay explores what I call an Anthropocene viewing condition, a contemporary spectator position in which images of nature, particularly moving images of natures past, resonate with present and future environmental loss. Analyzing natural disaster melodramas such as The Trail of ’98 (1928) and Deluge (1933) alongside popular science films about glaciers from the 1920s, I explore endangerment as both an explicit and latent structure of feeling in the Anthropocene.
Performing Invisible Stories through Creative History
Authors: Wells Julia C.
Published: February 2022

The recovery of the responses of Southern African people to colonial conquest two hundred years ago is complex. Their feelings must be deduced from their actions, as recorded in hostile written records. A two-person play, Umnqa!—Never Defeated portrays the fighting spirit of a young man who eluded colonial controls three times. Produced in 2015–16 in the context of militant student unrest demanding intellectual inclusiveness, the performance aimed to engage nonacademic audiences and speak to their experiences. Grounded in the theories of Paolo Freire, it became a foundational example of an emerging creative history methodology which promotes a robust partnering of history and art to tell partly imagined stories.

La pandemia ocasionada por el virus de la COVID-19 determinó que se tomaran medidas sanitarias que afectaron el normal desarrollo, no solo de las actividades laborales sino también de las académicas. La prohibición de la presencialidad en las universidades, específicamente en las facultades de odontología donde la actividad clínica en los últimos tres años de estudio es fundamental para el desarrollo de las competencias procedimentales y actitudinales quedaron totalmente suspendidas. El presente artículo tiene como objetivo revisar el uso de los simuladores pospandemia, como una tecnología que permita, gracias a sus alcances, suplir la presencia de los pacientes. Para ello se realizó una búsqueda de artículos científicos en las siguientes bases de datos: Google académico, MEDLINE/PubMed, SciELO, Scopus y LILACS, durante los años 2020-2021; los artículos recolectados estuvieron relacionados con la importancia del uso de simuladores en el desarrollo de las competencias requeridas. De acuerdo con los resultados obtenidos se pudo determinar que el uso de esta tecnología permitió básicamente desarrollar habilidades, destreza y confianza en los estudiantes sin tener que poner en riesgo la salud e integridad física del paciente, con la posibilidad de evaluar y repetir los procedimientos realizados indeterminadamente.
A New Hybrid Fuzzy Multi-Criteria Decision Methodology for Prioritizing the Antivirus Mask Over COVID-19 Pandemic
Authors: Kaya Sema Kayapinar , Pamucar Dragan , Aycin Ejder
Published: February 2022

During the COVID-19 pandemic, masks have become essential items for all people to protect themselves from the virus. Because of considering multiple factors when selecting an antivirus mask, the decision-making process has become more complicated. This paper proposes an integrated approach that uses F-BWM-RAFSI methods for antivirus mask selection process with respect to the COVID-19 pandemic. Finally, sensitivity analysis was demonstrated by evaluating the effects of changing the weight coefficients of the criterion on the ranking results, simulating changes in Heronian operator parameters, and comparing the obtained solution to other MCDM approaches to ensure its robustness.

Operator of Photon Density in the Phase Space
Authors: Chumak O. , Sushkova N.
Published: February 2022

The possibility to describe the evolution of an electromagnetic field by means of the photon distribution function in the phase space (r, q-space) is studied. This function defined by analogy with the coarse-grained Mandel operator of photon density in the configuration space is used to characterize the local density of photons with a given momentum. Approximate eigenfunctions and eigenvalues of the distribution function, corresponding to one-photon localized states of the electromagnetic field, are obtained. It is shown that the photon transport is governed by the Newton mechanics if the "external force" acting on photons is a slowly varying function of spatial variables. It is shown that the distribution function at any time can be expressed via the initialdistribution and photon's trajectories.

Published: February 2022

OBJECTIVE

To prospectively evaluate the long-term impact of Kawasaki disease (KD) hospitalization on health-related quality of life (HRQoL).

METHODS

We merged the Outcomes Assessment Program and KD databases and queried for KD admissions between 1 month and 18 years of age. Patients with a diagnosis of community-acquired pneumonia were included as a comparison group. HRQoL was evaluated with the parent proxy Pediatric Quality of Life Inventory (PedsQL). Long-term follow-up PedsQL surveys were performed at least 1 year after initial diagnosis and hospitalization. Results for the entire cohort adjusted for significant differences were calculated. Propensity score–matched cohorts were constructed from the unmatched cohorts of patients with long-term survey responses. Subgroup analysis for the KD group was performed.

RESULTS

Patients with KD (n = 61) versus pneumonia (n = 80) had a lower PedsQL total score on admission and experienced a significantly greater HRQoL decline from baseline to admission. At long-term follow-up, no difference occurred in HRQoL between patients with KD and pneumonia, and 89% of patients with KD reached their baseline PedsQL scores. KD diagnostic subtype, coronary artery dilatation, and need for longer follow-up were not associated with HRQoL outcomes at any time point. Intravenous immunoglobulin nonresponders demonstrated lower HRQoL at admission, which did not persist at follow-up.

CONCLUSIONS

Children with KD experience acute and significant HRQoL impairment exceeding that of children with newly diagnosed pneumonia, but the scores return to baseline at long-term follow-up. The recoveries at short- and long-term intervals are similar to patients with pneumonia.

El objetivo de esta investigación fue generar el modelo conceptual que ha permitido la evolución y el crecimiento del Tianguis y Plaza Ganadera Ejidal Puente San Bernabé en Almoloya de Juárez, como punto de encuentro para la comercialización de productos diversos. Se inició con la ubicación del sitio dentro de un marco regional y estatal; se identificaron los giros comerciales y se dio el reconocimiento de los actores involucrados. Se realizaron aforos de afluencia peatonal y se revisó del crecimiento superficial en el tiempo; finalmente, se evaluó la información recolectada para formular la propuesta de modelo conceptual. Se ha obtenido que los giros comerciales han sido el motor de supervivencia, aún por encima de otros mercados cercanos, la accesibilidad de precios y la disponibilidad de espacios, verificado al realizar ciclos iterativos en el modelo conceptual. Sin embargo, quienes intercambian sus productos son los menos favorecidos. De esta forma, a pesar de la marginación, la competitividad con comercios establecidos, la volatilidad de los precios y la ubicación rural, el actual Tianguis ha tenido un crecimiento de más del 260% en los últimos 17 años gracias a la diversidad de productos que se comercializan cada lunes.

Published: February 2022

El propósito de este artículo es analizar los significados sociales atribuidos a la escolarización rural en el estado de Tamaulipas, México. Se realizó un estudio de caso en el ejido El Tigre, de enero de 2015 a diciembre de 2018, mediante un diseño narrativo con distintos actores educativos. Se concluyó que el sistema educativo genera distancias entre la lógica escolar y la vida rural. No obstante, la comunidad legitima a la escuela como parte de su entorno cotidiano y la significa como el mundo en donde encuentra un reconocimiento social, existencial y jurídico.
MILITANTES SINDICALES EN JUJUY, ARGENTINA. UN ESTUDIO DEL COMPROMISO POLÍTICO DESDE LA PERSPECTIVA DE CARRERA
Authors: Berardi Spairani Adrián Pablo
Published: February 2022

Este artículo analiza la militancia sindical en la provincia de Jujuy, Argentina, entre los años 2015 y 2017. El objetivo es dar cuenta de los elementos que condicionan y determinan el compromiso político de este tipo de militancia. Se trabajó con un enfoque microestructural y se recurrió a una metodología cualitativa a partir del relato de vida. Así, se pudo identificar que las carreras militantes comparten secuencias que son comunes, pero las prácticas políticas y las miradas respecto de su propia militancia difieren en tanto están condicionadas por sus espacios de participación.

To reveal the effects of Oldenlandia diffusa (OD) on relieving the progression and development of gestational diabetes mellitus (GDM), and explore the underlying mechanism. A rat model of GDM was established by streptozotocin injection. The effects of OD on GDM rats were evaluated by measuring the levels of fasting blood glucose (FBG), insulin, and hemoglobin A1c (HbA1c), and exposing to oral glucose tolerance test (OGTT) and histological evaluation of the pancreas. The levels of insulin and inflammation response-related factors (tumor necrosis factor [TNF]-α, Interleukin [IL]-6 and IL-1β) were evaluated by enzyme-linked immunosorbent assay (ELISA). Additionally, immunoblot assay was performed to investigate the effects of OD on the nuclear factor-κb (NF-κB) pathway and 5' adenosine monophosphate-activated protein kinase (AMPK) pathway. OD decreased blood glucose level, pancreatic tissue damage, and insulin secretion in GDM rats. OD also reduced serum inflammatory levels (TNF-α, IL-6, and IL-1β) in GDM rats. Mechanically, OD could inhibit NF-κB pathway and activate AMPK pathway in the pancreatic tissue of GDM rats. OD affected glucose metabolism and inflammation level in rats with streptozotocin-induced GDM, and the underlying mechanism was through AMPK pathway. OD might serve as a promising and potential drug for the treatment of GDM.
Neural Character-Level Syntactic Parsing for Chinese

Published: February 2022

In this work, we explore character-level neural syntactic parsing for Chinese with two typical syntactic formalisms: the constituent formalism and a dependency formalism based on a newly released character-level dependency treebank. Prior works in Chinese parsing have struggled with whether to de ne words when modeling character interactions. We choose to integrate full character-level syntactic dependency relationships using neural representations from character embeddings and richer linguistic syntactic information from human-annotated character-level Parts-Of-Speech and dependency labels. This has the potential to better understand the deeper structure of Chinese sentences and provides a better structural formalism for avoiding unnecessary structural ambiguities. Specifically, we  first compare two different character-level syntax annotation styles: constituency and dependency. Then, we discuss two key problems for character-level parsing: (1) how to combine constituent and dependency syntactic structure in full character-level trees and (2) how to convert from character-level to word-level for both constituent and dependency trees. In addition, we also explore several other key parsing aspects, including di erent character-level dependency annotations and joint learning of Parts-Of-Speech and syntactic parsing. Finally, we evaluate our models on the Chinese Penn Treebank (CTB) and our published Shanghai Jiao Tong University Chinese Character Dependency Treebank (SCDT). The results show the e effectiveness of our model on both constituent and dependency parsing. We further provide empirical analysis and suggest several directions for future study.
Security in SDN networks and their applications

Introduction: The review article is the product of the research on Security in SDN networks and their applications, developed at the District University in 2020, presenting the latest advances, that have been made in security.

Problem: The security weaknesses that SDN networks have had, due to being a new architecture. This has not allowed traditional networks to be replaced.

 

Objective: To carry out a review of the state of the art of SDN networks, focusing research on the security of the control layer and its advances.

Methodology: The descriptive method is implemented, consulting databases such as Scopus, IEEE and ScienceDirect, using the following search criteria: SDN networks, security in SDN networks, applications with SDN networks and OpenFlow protocol. It is shown as a research sample: the Asian, European and American continents with years of research from 2014 to 2020.

Results: Great advances have been made in terms of security for SDN networks, which allows us to see an early solution to the weaknesses that it currently faces.

 

Conclusion: SDN networks will solve all the challenges they face and will be consolidated as a solid and reliable architecture.

Objetivo: analizar las propiedades psicométricas de una escala para medir el deterioro de las relaciones sentimentales en jóvenes del departamento de Puno. Metodología: diseño no experimental, de corte transversal, tipo instrumental y de enfoque cuantitativo, está conformada por 600 sujetos que participaron voluntariamente del estudio a partir de una aplicación ambulatoria, no se utilizó algún tipo de muestreo, las características de la población muestran que la mayoría perecen a ambos géneros, sus edades son entre 18 a 26 años y todos ellos establecen una relación sentimental. Resultados: la escala “IRTEP”, en su versión traducida, posee un índice de validez (V= .958) a partir de la evaluación de cuatro criterios de evaluación (claridad, contexto, congruencia y dominio del constructo) en 6 jueces. Respecto a la validez de contenido, se obtuvo mediante las pruebas de KMO y esfericidad de Bartlett cuyos valores (KMO= .942; p<,05) indicarían que el instrumento es apropiado para un análisis factorial confirmatorio (AFC), la cual sugiere que el instrumento debe poseer un contenido distribuido en 4 factores fijos en la extracción, se logró explicar el 47,6% de la varianza explicada. Razones que llevaron a un análisis más detallado como lo son ecuaciones estructurales. Los hallazgos demostraron un RMSEA =,049 menor del ,05; CFI=,911 y un TLI=,903 ambos mayores del ,90; estos resultados demuestran un adecuado ajuste de modelo. Conclusión: el instrumento evidencia una buena consistencia interna y validez de constructo.

pasefRiQ_V1 v1
Authors: not provided lcmsmethods , Yuan Yuting , N Bumpus Namandje'
Published: February 2022

We have developed optimized methods for reporter ion quantification on a TIMSTOF Flex (TIMS B configuration) by iterative analysis of the TMT triple knock out yeast standard and an in-house developed two-proteome standard. For the greatest reduction in background coisolation interference in the TMT6 and TMT10/11 plex standards, 10 ion mobility ramps from 0.8 to 1.3 1/k0 provides the greatest reduction in interference on 60 minute LC gradients when using a 25cm IonOpticks aurora column. Reducing the number of ramps to 5 leads to an overall increase in peptide identifications with a loss in unique protein identifications. It is worth noting that the distribution of 1/k0 of peptides labeled with the TMT6/10/11plex and TMTPro reagents have somewhat different overall distibutions. For the maximum intrascan linear dynamic range. For 30 minute pasefRiQ experiments, 10 ramps at a 2.2 second cycle time has a detrimental effect on the overall identification of PSMs, peptides and proteins. For the highest possible coverage of each protein identified with the TMTPro reagents on 30 minute gradients we recommend 5 ramps using a 1/k0 range of 0.7 to 1.4. Typical results for pasefRiQ using a two proteome standard as described is 3,600 quantified proteins in 60 minutes with a 240ng total load on column. At 24ng load on column, this same method with no alterations will return approximately 2,100 quantified proteins. Increasing the multiplier voltage with the high sensitivity model will result in an approximately 15% more peptides and proteins identified at this load.
