A correlation study of military psychological stress, optimistic intelligence quotient, and emotion regulation of Chinese naval soldiers
Authors: Cui Yi , Zhang Xinchi , Liu Na , Liu Qin , Zhang Lanfang , Zhang Yinling
Published: May 2022

Psychological stress is closely related to the mental and physical health of soldiers. We explored the relationships between stress, optimistic intelligence, and emotion regulation in Chinese Navy personnel (N = 452), who completed the General Information Questionnaire, the Psychological
Stress Self-Evaluation Test, the Chinese Adult Optimistic Intelligence Quotient Questionnaire, and the Emotion Regulation Questionnaire in this cross-sectional study. Results show that stress was negatively correlated with perceived happiness and the ability to respond positively to negative
events, and positively correlated with emotional regulation, cognitive reappraisal, and expressive suppression. These findings indicate that comprehensive measures using positive psychology techniques should be taken to reduce stress among naval soldiers to enhance their well-being and the
military's combat readiness.
“Cover your mouth and nose”: communication about health protection behaviors by role models in YouTube COVID-19 videos for children
Authors: Steinke Jocelyn , Lin Carolyn A. , Duncan Tamia , Zambrano Viviana
Published: May 2022

YouTube videos offer a potentially useful vehicle for the communication of science, health, and medical information about COVID-19 to children. Findings from this research showed that primary characters appearing in children's educational YouTube videos about COVID-19 were most often adults, with about an equal number of men and women and few characters from diverse racial and ethnic backgrounds. Primary characters frequently demonstrated and modeled protective health measures. Adult expert characters (medical professionals and scientists) appeared to some extent in these videos. Directive discourse frames appeared most frequently, followed by the informative and persuasive discourse frames when communicating scientific and health information. Changes in the use of informative, directive, and persuasive frames before and after the U.S. Centers for Disease Control (CDC) announced guidelines on how to communicate about COVID-19 with children are explored.
dilema de la racialización: entre negridad e indianidad en la frontera México-Estados Unidos
Authors: Gil Martínez de Escobar Rocío
Published: May 2022

Basada en investigación etnográfica y de archivo en la región fronteriza entre Coahuila (México) y Texas (Estados Unidos), en este trabajo examino los procesos históricos de racialización de la población afroindígena negros mascogos / black seminoles. Argumento que las y los negros mascogos / black seminoles han estado atrapados en un dilema: desde el siglo XIX sus relaciones con dos Estados nación han empujado a procesos Nde racialización en los que la negridad y la indianidad aparecen como mutuamente excluyentes; sin embargo, algunos miembros de esta población empiezan a reivindicar su afroindianidad como política de resistencia. Este caso permite complejizar nuestra comprensión sobre las dinámicas de racialización, en la medida en que devela la importancia de entenderlas en su especificidad histórica, socioespacial y desde un ángulo relacional que trasciende las fronteras de los Estados nación.
Variación funeraria y condiciones de vida de La Jagua, Alto Magdalena, Colombia, y sus implicaciones para el periodo Reciente
Authors: Rodríguez-Cuenca José Vicente
Published: May 2022

En La Jagua (Garzón, Huila) se excavó un cementerio prehispánico cuyo uso principal se dio en el periodo Reciente. El hallazgo contribuye a la discusión sobre el cambio social y su influencia en las condiciones de vida de la población prehispánica. Igualmente, sirve para evaluar las hipótesis de los cronistas sobre la existencia de “barbarie, canibalismo y estado de guerra permanente” en las sociedades indígenas de contacto (López [1570] 1970, 55). Se procedió a un análisis estadístico multivariado de 338 tumbas correspondientes a los periodos Precerámico, Formativo, Clásico Regional y especialmente del Reciente, con el fin de evaluar la variación social en el tiempo y el espacio. Como resultado, se encuentra diferenciación espacial entre la terraza alta, que concentra la mayoría de tumbas profundas de pozo y cámara con objetos suntuosos, y la terraza media, cuyas tumbas son más sencillas. Cronológicamente se aprecia desde el Precerámico la continuidad de la tradición de las tumbas monticulares que recubren el cuerpo con cantos rodados de tamaño medio, muy diferente a la registrada en San Agustín-Isnos. En el Reciente, a pesar de la mayor diferenciación social, no se evidencia una gran acumulación de bienes ni en los indicadores de salud, aunque sí por sexo. Igualmente, mediante el análisis del patrón de lesiones no se corrobora la existencia de canibalismo ni de guerra permanente.
Crátilo, una práctica dialéctica en y con los nombres
Authors: López Juan Manuel
Published: May 2022

El texto aborda el problema de la dialéctica como una práctica discursiva valiéndose de una reflexión sobre el lenguaje, la cual se consigna a lo largo de Crátilo. La dialéctica platónica es el corazón de la filosofía del autor. Interpretada en algunas ocasiones como ciencia (ἐπιστήµη Rep. 366 c 7, 438 c 6,511 c 5), método (µέθοδος 262 c 10 - 269 c 6) o técnica (τέχνη Fedro 276 e 5 - 277 e4), la dialéctica se reduce a un simple método de razonamiento, en algunos casos emparentado con la lógica. En esta dirección, ella señala el discurso hablado como su frontera (διαλέγω). No obstante, el problema que nos deja esta piedra angular de la filosofía platónica va mucho más allá. Esta debe ser entendida, y hacia allá apunta la propuesta, como una práxis que se sirve del lenguaje (διάλεκτος), tanto hablado como escrito, pero que no se agota en él. La práctica dialéctica, como lo ha señalado el profesor Francisco Gonzales (1998), puede medirse en lo que Platón indica temáticamente sobre ella, tanto como en lo que se trasluce en la interacción de sus personajes: en los recursos formales en juego para la lectura del autor (tercera vía de interpretación). El Crátilo platónico que ha sido considerado contemporáneamente como un diálogo cercano a la comedia, o como una ironía lingüística, adquiere mediante esta concepción una posibilidad de relectura.
Nuevo horizonte poético de la lengua española II el hombre planetario Jorge Carrera Andrade
Authors: Peláez Pérez Carlos Eduardo
Published: May 2022

Jorge Carrera Andrade es el poeta y prosista ecuatoriano que mayor valor le ha concedido a la tierra como lugar de la poesía. La concepción de la imagen como una creación que está al interior de las cosas y que puede ser develada por el lenguaje, coloca su poesía en una paradoja fundamental: la finitud eterna de la vida. Esa finitud envuelve también al lenguaje y éste le permite que el tiempo sea medido con la clepsidra del futuro, donde las cosas finitas son, se relacionan en sí mismas y señalan que el momento de su perecer es el comienzo de una nueva fuerza vital. Su poesía, una lectura al corazón humano, es la armonía de la libertad y la fraternidad. Estos prismas de la modernidad, hacen de la creación de Carrera Andrade un movimiento donde brota la vida sin jamás colmarse, de allí que la crítica, el desacuerdo con lo establecido social y tecnológicamente, sean los renglones que no caducan, la transitoriedad que no se detiene, la muerte que no tiene comienzo.
Allicin Ameliorates IMQ-induced psoriasis-like Skin Inflammation Via Disturbing the Interaction of Keratinocytes with IL-17A
Authors: Zhang Lu , Ma Xuehong , Shi Rongmei , Zhang Libo , Zhao Ruolin , Duan Ran , Qin Yuanyuan , Gao Sijia , Li Xinxia , Duan Jingjing , Li Jianguang
Published: May 2022

Background and Purpose: Psoriasis is an inflammatory skin disease of
chronic recurrence mediated by the interaction between IL-17 and
keratinocytes, which sustains a vicious circle of inflammation.
Currently, there is no safe and effective natural medicine for the
clinical treatment of psoriasis. Given its prominent anti-proliferative
and anti-inflammatory properties, we investigated the mechanism of
allicin improving psoriasis. Experimental Design: Pharmacodynamics and
toxicology experimental studies were estimated after topical
administration of allicin on the skin of mice. Changes in inflammatory
factors expression were analyzed by qPCR and immunohistochemistry after
topical treatment with allicin in mice with psoriasis-like lesions
induced by imiquimod. The impacts of allicin on proliferation and
apoptosis of keratinocytes were analyzed by CCK8 assay and flow
cytometry. The interaction between IL-17A and keratinocytes was studied
using HaCaT cells, and the mechanism of action of allicin was explored
by Western Blot. Transcriptomic changes following the action of allicin
were probed by RNA-seq. Key Results: Our study demonstrated that allicin
significantly improved the epidermal structure by inhibiting excessive
proliferation and evasion of apoptosis of keratinocytes. Furthermore,
allicin reduced the secretion of inflammatory cytokines (IL-17A/F,
IL-22, IL-12, IL-20), chemokines (CXCL2, CXCL5, CCL20), and
antibacterial peptides (S100A8/9). Mechanistically, allicin directly
inhibited the IL-17-induced TRAF6/MAPK/NF-κB and STAT3/NF-κB signaling
cascades in keratinocytes, thus breaking the positive inflammation
feedback and alleviating imiquimod-induced psoriasis-like dermatitis in
mice. Importantly, topical administration of allicin did not cause skin
allergy, and the safety and adaptability of long-term application were
verified.
Explainable Fragment-based Molecular Property Attribution

Published: May 2022

“AI & Drug Discovery” mode has significantly promoted drug
development and achieved excellent performance, especially with the
rapid development of deep learning, making remarkable contributions to
protecting human physiological health. However, due to the “black-box”
characteristic of the deep learning model, the decision route and
predicted results in different research stages assisted by deep models
are usually unexplainable, limiting their application in practice and
more in-depth research of drug discovery. Focusing on the drug
molecules, we propose an explainable fragment-based molecular property
attribution technique for analyzing the influence of particular molecule
fragments on properties and the relationship between the molecular
properties in this paper. Quantitative experiments on 42 benchmark
property tasks demonstrate that 325 attribution fragments, which account
for 90% of the overall attribution results obtained by the proposed
method, have positive relevance to the corresponding property tasks.
More impressively, most of the attribution results randomly selected are
consistent with the existing mechanism explanations. The discovery
mentioned above provides a reference standard for assisting researchers
in developing more specific and practical drug molecule studies, such as
synthesizing molecular with the targeted property using a fragment
obtained from the attribution method.

Automated & Easy Diagnosis of Cervical Cancer From Onsite Easy Colposcopy Images
Authors: Bhattarai Devi , Khanal Bishesh
Published: May 2022

Lifestyle and early diagnosis can bring a drastic change in  Cervical
cancer patient Infections when diagnosed early enough that makes it easy
to prevent. By the time symptoms appear, cancer might have manifested
itself and begun to spread. Due to poor access to preventive and
treatment services, a vast number of unfortunate deaths occur
needlessly. Enhancing the prevalent method of treatment and diagnosis,
deep learning models have been proved to be more precise and accurate
than mere Visual Inspection by specialists. AI-assisted colposcopy
reduces time and effort it takes for a gynecologist to gain an expertise
and thus spares more time to improve other skills, training and
activities.Here, we use Supervised(unsupervised) algorithms in order to
classify the colposcopy images. To attain our target, we collect a large
number of image datasets requested to ABC hospital and are categorized
by our system to different stages of cancer, results of which can be
further analyzed by specialists to imply appropriate clinical procedures
of cure. The successful deployment promotes low-cost mobile technology
to facilitate millions of women across the country who earlier had
limited access to life-saving cancer tests. As the morbidity and
mortality rates of cervix cancer are pretty high, early detection and
treatment of the abnormal tissues or pre-cancerous cells is the ultimate
solution to it. This study is useful to diagnose an early metamorphosis
of cancerous cells more accurately and hence helps to drop down the
death rate even in any low-middle resources areas of the country.

Comparative analysis of the structure of water-soluble LCCs and the Björkman LCCs in poplar wood
Authors: CUI SHENG , Xie Yimin , Wei Xin , Chen Xundong
Published: May 2022

The structural study of lignin-carbohydrate complexes (LCCs) provides a
theoretical basis for the high-value utilization of biomass which has
always been a hot topic in biomaterials and biomass refining. This paper
compares the structure of two types of LCCs in poplar. After poplar wood
was crushed by ball milling, water-soluble LCCs and the Björkman LCCs
were extracted by hot water extraction and the Björkman classical
method, respectively. The molecular weight was determined by GPC, the
composition was determined by chemical analysis, and the structure was
studied by UV, IR and 2D-NMR. Comparing the two, the results showed that
water-soluble LCCs contains a higher content of carbohydrates and has a
relatively wide molecular weight distribution, while the carbohydrate
content of the Björkman LCCs was relatively low, and the molecular
weight distribution range was relatively narrow. UV, IR and 2D-NMR
results confirmed that the main chemical links between the lignin units
of the two LCCs were β-O-4. β-β, β-5 structures. The chemical linkages
between lignin and carbohydrates in water-soluble LCCs were mainly
phenyl glycosidic bonds and ester bonds, while in the Björkman LCCs,
there were not only have phenyl glycosides bonds and ester bonds, but
also found existence of ether bonds between lignin and carbohydrates.
This work contributes to a comprehensive understanding of the structure
of poplar LCCs and provides theoretical support for the further
application of poplar wood.
Use molecular barcodes to study emerging infectious diseases
Authors: Chen Heng-Chang
Published: May 2022

The appearance for viruses that evolve to adapt to a new living niche
often reflect on viral sequence changes. Fixation of these changes may
require a long time through repeated transmission, thereby rendering a
reduced size of an effective population harboring dominant alterations
in their sequence spaces. Those approaches, with which we can closely
monitor and survey the transient changes of viral sequences over the
longer timescales, thus become a requisite to better understand the
evolution of viral pathogenicity. Molecular barcodes are a powerful and
practical molecular tool to individually label sequences, allowing for
correcting sequencing errors and identifying true mutants of interest
with a single nucleotide resolution. Molecular barcoding has also been
implemented as a useful approach to study several zoonotic viruses. In
this review, the emphasis will not only be limited to summarize current
studies focusing on viral pathogenesis and fitness; we will also propose
ideas that molecular barcodes can be used to execute surveillance of
changes of viral sequences. We believe that this review will be helpful
for the readers to better understand the rationale and the usage of
molecular barcodes and the perspectives of what molecular barcodes can
do for fighting upcoming emerging infectious diseases.
Perceptions of Organizational Politics among Public Sector University Faculty

Published: May 2022

The fact that politics exist in Pakistani associations is true for the education sector too. This research distinguished whether maintaining, moving higher in a brief time frame, in the hierarchy of a higher education institution, is through belongingness or is it through labour and capability. This study investigated the existence of politics among the teachers of public sector higher education institutions and is structured around the Perceptions of Organizational Politics (PoPs) developed by Kacmar and Carlson (1997). The data was collected in two phases: the first phase included the collection of quantitative data from 367 university faculty and in the second phase 15 university Deans/ HoDs were interviewed for triangulation. The data collected was analyzed using SPSSv-22.0. The results of the research established that politics exists at the university level and that seats of learning are not exempted from the evil of politics; teachers act the same way as workers in any other organization. The research likewise brought to the fore a solid relationship between workers' apparent contentment with regards to pay and advancement and organizations' compensation and advancement guidelines.

Published: May 2022

Objectives: we aimed to compare the diagnosis accuracy between US and MRI in the diagnosis of full-thickness and partial-thickness rotator cuff tears and biceps tendon tears with arthroscopy used as the reference standard. Methodology: Comprehensive electronic search with time and language restrictions was conducted. Several known databases were included Ex: “PubMed, The Cochrane Library, Web of Science” from 2020 to 2020. We combined the search terms and limited the study to the English language. Depending on PRISMA checklist we would remove duplicates, articles would be screened based on title, abstract, and full text. Results: The electronic search strategy conducted in this review ended in 875 hits which after removing of duplicated reduced to 360 studies. These 360 studies were considered eligible for further evaluation, from which 348 studies were excluded for different reasons as 245 studies based on title and abstract, 86 studies do not relevant to the subject of this study or sitting of this review, 17 consider replies of authors, 2 books, and 28 were reviews. At end, 12 articles were included in the qualitative synthesis of the present review. Conclusion: we found that MRI had slightly better superiority than its accuracy, sensitivity and specificity especially, in Full and intact rotator cuff injuries. However, according to previous studies the use of US is still good because of its good sensitivity and specificity and cost- effective approach.

Published: May 2022

Background: Transcatheter aortic valve implantation (TAVI) has emerged as an effective and safe treatment for severe aortic stenosis in the last decades compared for surgical aortic valve replacement. However, it stills associated with high risk of conduction abnormalities requiring pacemaker implantation. Our study aimed to examine factors associated with transient conduction abnormities that don’t require pacemaker on long term. Methods: Retrospective analysis of all consecutive patients who underwent TAVI between 2010 and 2019 in Kaplan Medical Center, Rehovot, Israel. Results: Pre-TAVI haemoglobin levels were significantly lower in patients who developed transient CA compared to patients who develop persistent conduction abnormalities and were pacemaker dependent on follow up. Similarly, urea levels were higher in in patients with transient conduction abnormalities. Conclusion: Transient conduction abnormalities following TAVI are not uncommon. Correction of anaemia and volume depletion prior to TAVI may decrease the incidence of these transient conduction abnormalities and hence, decrease the fraction of unnecessary permanent pacemaker implantations in the long term. Watchful waiting may be wise in anaemic patients who develop CA after TAVI. The cut-off for haemoglobin levels prior to TAVI is yet to be determined.

Kompetensi pedagogik adalah kemampuan yang diperlukan oleh seorang guru dalam mengelola pembelajaran. Upaya meningkatkan kompetensi pedagogik guru perlu dilaksanaklan secara berkelanjutan. Kegiatan e-mentoring dapat memfasilitasi guru untuk meningkatkan kompetensinya, tanpa harus meninggalkan tugas dan jadwal mengajar. Tujuan penulisan paper ini adalah untuk mengkaji e-mentoring sebagai salah satu alternatif upaya meningkatkan kompetensi pedagogik guru, serta strategi e-mentoring yang sesuai untuk diterapkan dalam upaya tersebut. Penulisan paper dilaksanakan dengan menerapkan metode kajian literatur. Berbagai literatur menyebutkan bahwa peserta baik mentor maupun mentee merasakan dampak positif dari program e-mentoring terhadap kepercayaan diri, dan peningkatan kompetensi pedagogik, secara khusus yang terkait dengan perencanaan pembelajaran dan praktik mengajar di kelas. Salah satu strategi e-mentoring yang dapat diterapkan adalah model e-mentoring DARP yang merupakan akronim dari Discuss Archive Reflect dan Prepare, tiap alur e-mentoring dilaksanakan dengan memanfaatkan TIK. Faktor yang dapat mempengaruhi keberhasilan program e-mentoring yaitu, kerangka kerja desain e-mentoring yang sesuai dan sistematis, literasi TIK sebab peserta dalam proses pendampingan tersebut perlu secara aktif terlibat dengan media baik secara sinkron atau asinkron, pada akhirnya kunci kesuksesan suatu kegiatan e-mentoring terletak pada hubungan antar individu yang saling percaya, saling menghargai dan juga komitmen mentor maupun mentee.

STUDENTS’ PERCEPTIONS ON THE USE OF L1 IN EFL LEARNING
Authors: Anindya Alya Sekar
Published: May 2022

The use of first language (L1) in EFL classrooms is considered taboo since it is believed to hinder students’ foreign language (L2) development, while others support it due to its benefits in facilitating students’ access to L2. Hence, this study attempts to investigate students’ perceptions on the use of L1 in EFL classrooms. In this qualitative study, the data were collected through observations and interviews with three selective respondents. The findings reveal the students’ positive perception on the use of L1 in their EFL learning. Mediated by L1, the students were able to understand and engage well to EFL learning, which they believe would help shape and develop their English. Despite the benefits, they agree on some restrictions made by EFL teachers to provide opportunities for students to practice their English. Some suggestions for EFL teachers are postulated.
