PROMOTING THE TEACHER EDUCATION OF POST-GRADUATE STUDENTS IN CHEMISTRY: A CASE STUDY IN THE DISCIPLINE OF INTERNSHIP TEACHING. The objective of this work was to identify evidences related to the teacher knowledge and professional identity characteristics developed by post-graduate students in Chemistry during a discipline of Teaching Internship and Teaching Methodology in Chemistry from a Federal University. The activities carried out were leaned on the discussion of chemistry teaching aspects, planning, developing and reflection about teaching experiences. The teacher education process was analyzed by students themselves by means of metacognitive reports that was employed as data research and examined using content analysis to investigate their teacher knowledge development. The results pointed out the appropriation as much teacher knowledges as aspects of teacher professional identities: search for a flexible and singular didactic-pedagogical profile; belief in constant training/ qualification; difficulties and social obligation of the profession. Such results show that the activities proposed can be useful and adaptable to the reality of each post-graduate program in Chemistry. The approach is an opportunity and an incentive for post-graduate tudents to seek other teaching qualifications during the journey to become a university professor. Despite having contributed to teacher development, just a discipline is not enough to encompass the complexity of this process.

The Anti-osteoporosis Effects of Vitamin K in Postmenopausal Women
Authors: Liu Yuan , He Yuan , He Baorong , Kong Lingbo
Published: May 2021

As a common systemically muscular-skeleton disorder of aging, osteoporosisis is characterized
by the uninterrupted deconstruction in osseous microarchitecture. Osteoporosis can consequently
lead to a significantly high risk of osteoporotic fractures, such as osteoporotic vertebral
compressive fractures [OVCF] in the spine and osteoporotic femoral neck fractures in the hip joint,
which can significantly increase the numbers of mortality and morbidity in elderly people, especially
in postmenopausal women. In addition, vitamin K has been demonstrated to play a key role in inhibiting
osteoporotic fractures among postmenopausal women, but its long-term benefits, potential
harms, and side effects of the combination between vitamin K and other anti-osteoporosis
medicines, such as bisphosphonates or teriparatide still remain to be extensively studied.Therefore,
the present study aimed to systematically reviewed previously published literature on the role of vitamin
K in the treatment of osteoporosis.We currently, via multiple query strategies, searched the
relevant literature in Cochrane and PubMed from January 2010 to December 2019. Subsequently,
we conducted the systematic review according to the standard guideline of Preferred Reporting
Item for Systematic Reviews and Meta-Analyses [PRISMA]. Finally, ten relevant studies met our
current criteria for inclusion; subsequently, we followed the PRISMA guideline, then systematically
reviewed each study by categorizing the data sources and analytical approaches in each study,
while setting up variables and defining each study's outcomes.

Background

When children suffer sudden illness or injury, many parents wonder whether they should go to the hospital immediately or call an ambulance. In 2015, we developed a mobile app that allows parents or guardians to determine the urgency of their child’s condition or call an ambulance and that indicates available hospitals and clinics when their child is suddenly sick or injured by simple selection of the child’s chief complaints and symptoms. However, the effectiveness of medical apps used by the general public has not been well evaluated.

Objective

The purpose of this study was to clarify the use profile of this mobile app based on data usage in the app.

Methods

This study was a descriptive epidemiological study with a 4-year study period running from January 2016 to December 2019. We included cases in which the app was used either by the children themselves or by their parents and other guardians. Cases in which the app was downloaded but never actually used were excluded from this study. Continuous variables are presented as median and IQR, and categorical variables are presented as actual number and percentages.

Results

The app was used during the study period for 59,375 children whose median age was 1 year (IQR 0-3 years). The app was used for 33,874 (57.05%) infants, 16,228 (27.33%) toddlers, 8102 (13.65%) elementary school students, and 1117 (1.88%) junior high school students, with 54 (0.09%) having an unknown status. Furthermore, 31,519 (53.08%) were male and 27,329 (46.03%) were female, with sex being unknown for 527 (0.89%) children. “Sickness” was chosen for 49,101 (78.51%) patients, and “injury, poisoning, foreign, substances and others” was chosen for 13,441 (21.49%). For “sickness,” “fever” was the most commonly selected option (22,773, 36.41%), followed by “cough” (4054, 6.48%), and “nausea/vomiting” (3528, 5.64%), whereas for “injury, poisoning, foreign substances and others,” “head and neck injury” was the most commonly selected option (3887, 6.22%), followed by “face and extremities injury” (1493, 2.39%) and “injury and foreign substances in eyes” (1255, 2.01%).

Conclusions

This study clarified the profile of use of a self-triage app for pediatric emergency patients in Japan.

Background

The clinical, laboratory, and imaging features of COVID-19 disease are variable. Multiple factors can affect the disease progression and outcome.

Objective

This study aimed to analyze the clinical, laboratory, and imaging features of COVID-19 in Jordan.

Methods

Clinical, laboratory, and imaging data were collected for 557 confirmed COVID-19 patients admitted to Prince Hamzah Hospital (PHH), Jordan. Analysis was performed using appropriate statistical tests with SPSS version 24.

Results

Of the 557 COVID-19 polymerase chain reaction (PCR)-positive cases admitted to PHH, the mean age was 34.4 years (SD 18.95 years; range 5 weeks to 87 years), 86.0% (479/557) were male, 41% (29/70) were blood group A+, and 57.1% (93/163) were overweight or obese. Significant past medical history was documented in 25.9% (144/557), significant surgical history in 12.6% (70/557), current smoking in 14.9% (83/557), and pregnancy in 0.5% (3/557). The mean duration of hospitalization was 16.4 (SD 9.3; range 5 to 70) days; 52.6% (293/557) were asymptomatic, and 12.9% (72/557) had more than 5 symptoms, with generalized malaise and dry cough the most common symptoms. Only 2.5% (14/557) had a respiratory rate over 25 breaths/minute, and 1.8% (10/557) had an oxygen saturation below 85%. Laboratory investigations showed a wide range of abnormalities, with lymphocytosis and elevated C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and D-dimer the most common abnormalities. Ground glass opacity was the most common imaging finding. Men had a significantly higher frequency of symptoms, incidence of smoking, reduced hemoglobin, increased monocyte %, elevated creatinine levels, and intensive care unit admissions compared with women (P<.05). Hospitalization duration was associated with increased age, male gender, symptom score, history of smoking, elevated systolic blood pressure, elevated respiratory rate, and elevated monocyte %, CRP, ESR, creatinine, and D-dimer (P<.05).

Conclusions

Most COVID-19 cases admitted to PHH were asymptomatic. Variabilities in symptoms, signs, laboratory results, and imaging findings should be noted. Increased age, male gender, smoking history, and elevated inflammatory markers were significantly associated with longer duration of hospitalization.

Young Undocumented Migrants in Contemporary Fiction Films: Guten Tag, Ramón and Ya no estoy aquí
Authors: Quintana Vallejo Ricardo
Published: May 2021

The last fifteen years have seen a rise in critically-acclaimed fiction films depicting undocumented migration from and through Mexico. By analyzing two illustrative examples—Guten Tag, Ramón (2013), and Ya no estoy aquí (2019)—this paper uses the framework of the coming-of-age genre to dissect the characteristics of this new contemporary cinematographic type, thus pondering its inner-workings and appeal. Moreover, the paper contrasts different factions of the critical reception these films in order to examine why such films are met with both punitive disdain and enthusiastic celebration. The differences in tone between these two films show how the themes of migration, poverty, and violence can be interpreted in varied ways that serve to call attention to their urgency. From the lighthearted humor of Guten Tag, Ramón to the poignant solemnity of Ya no estoy aquí, the cinematographic genre, so close to the archetypal plot of coming-of-age narratives, denounces both the indifference of the Mexican middle class and the xenophobic settings that seek to undermine the right to migrate.

Authors: Kärner O. Y. , Avaste O. A.
Published: May 2021

Se han utilizado para análisis armónico bidimensional los valores medios mensuales del albedo y de la radiación de onda larga emitida del sistema Tierra-Atmósfera. Las coordenadas son la latitud geográfica y el tiempo. Usando una malla de 2.so se determinaron los coeficientes armónicos para 71 zonas latitudinales. Los datos primarios utilizados son tres años de mediciones de satélites NOAA (Julio 1974 - junio 1977). Los resultados de los cálculos se analizaron agrupando los armónicos de la manera siguiente: dos grupos representando variabilidad espacio temporal independiente y un tercer grupo que tiene en cuenta esta variabilidad espacio temporal. El peso de los diferentes armónicos y grupos se estimó en términos de valores zonales anuales de la variación y las diferencias anuales en las amplitudes y fases de las armónicas.

Con base en diversas fuentes de información se elaboró el catálogo de la historia eruptiva del Volcán de Colima, México, para el período 1560 - 1980. Este volcán es actualmente el más activodel país, su historia eruptiva muestra una alta frecuencia de actividad de tipo explosivo,contándose por lo menos 29 erupciones de este tipo en los últimos 420 años."El análisis de los datos del catálogo muestra 57 períodos de reposo. La aplicación de los modelos estadísticos de Wickmann (1966) y Thorlaksson (1967) permitió la evaluación de la función de razón de erupción </l(t), la función de distribución para la longitud de los períodos de reposo F(t), y la función de densidad de probabilidad para la misma variable f(t). El análisis del comportamiento de estas funciones permite estimar un máximo en la probabilidad de ocurrencia de un nuevo período eruptivo para períodos de reposo menores de 18 años.

Authors: Reyes S. , Pares A.
Published: May 2021

Se analizan los datos de viento superficial de cuatro estaciones meteorol6gicas en la Bahm de Todos Santos, para estudiar el campo de viento local. Los métodos de análisis estadísticos, de espectros rotacionales y de componentes principales (EOF), son utilizados para describir las características del flujo de aire. Las máximas energías son observadas en las frecuencias diurnas y semidiurnas, lo cual pone en evidencia los procesos de brisa marina y terrestre y de convecci6n libre. Se observa que la brisa marina sobre la isla empieza con unas dos horas de retraso respecto a las estaciones costeras. La máxima energía de las frecuencias diurnas se encuentra en la e,taci6n de la isla, mientras que la energía mínima está en la estación de la ciudad, mostrando la importancia de la fricci6n; en las frecuencias semidiurnas se encuentra la energía máxima en la estaci6n de la ciudad y la mínima en la isla, mostrando la importancia de la convecci6n libre y del calentamiento del suelo sobre la tierra. El análisis EOF muestra la influencia del viento sinóptico sobre los autovectores principales, dando una componente sur a los valores esperados de la brisa mar-tierra. La brisa marina es, en promedio, dos veces más intensa que la brisa terrestre.
COVID-19 in South Korea: The Need for Preemptive Tests from the Perspective of Asymptomatic Infections
Authors: Sim Insuk , Kang Yun-Jung , Kim Hye Jeong
Published: May 2021

The first case of coronavirus disease reported in South Korea was a person infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), who entered South Korea from China on January 20, 2020. In the Capital, the Korean government applied the social distancing policy at level 2.5 for 8 days from August 30 to September 6, 2020. The Central Disease Relief Center explained that the reason the number of newly confirmed cases per day did not fall below 100 was because the infection spread nationwide through sporadic mass infections or asymptomatic patients. Asymptomatic infection with SARS-CoV-2 is a subject of constant controversies, as asymptomatic patients can infect other people while not showing any symptoms themselves. Their atypical clinical characteristics in the early stages of the disease make prevention more difficult. Additional studies on the infecting power of SARS-CoV-2 in asymptomatic cases are needed. Nonetheless, such probabilities should be taken into consideration and we should remain vigilant.

Authors: Che Xiaoli , Fakhrorazi A. , Wei-Kit Loke , Chen Qinyuan
Published: May 2021

In this study we aimed to promote Chinese public sector development and reduce the difficulty of management and motivation of knowledge workers (k-workers) in the public sector. We investigated if servant leadership influences leader–member exchange (LMX) and if k- workers’ LMX influences their task performance, as well as examining the mediating role of organizational citizenship behavior (OCB). We collected questionnaires from 383 k-workers in 10 Chinese public sectors via a self-administered survey, and used partial least squares structural equation modeling for data analysis. Results show that servant leadership had a positive relationship with LMX, LMX was positively related to OCB and task performance, and OCB had a mediating effect in the LMX–task performance relationship. Our results have theoretical implications, and our practical suggestions for managing, motivating, and inspiring k-workers will help promote the organizational performance of the Chinese public sector.

Para fomentar a discussão procurou-se na pesquisa documental a sustentação de análise das informações pelos documentos oficiais primários: Constituição de 1988, a LDBN/96, o PNE e a BNCC. Por meio de um olhar qualitativo buscou-se interpretar o objeto de investigação num movimento de reflexão para compreender o fenômeno que inspirou a pesquisa. A invisibilidade da EJA na BNCC revela o silêncio e a negação da modalidade nas políticas públicas da educação no Brasil no atual cenário. Refletir sobre a temática exige o desafio à luta. Um imperativo para os novos rumos da educação de Jovens e Adultos.
The hidden role of multi-trophic interactions in driving diversity-productivity relationships
Authors: Albert Georg , Gauzens Benoit , Loreau Michel , Wang Shaopeng , Brose Ulrich
Published: May 2021

Resource-use complementarity of producer species is often invoked to
explain their generally positive diversity-productivity relationships.
Additionally, multi-trophic interactions that link processes across
trophic levels have received increasing attention as a possible key
driver. Given that both are integral to natural ecosystems, their
interactive effect should be evident but has remained hidden. We address
this issue by analyzing diversity-productivity relationships in a
simulation experiment of primary producer communities nested within
complex food-webs, manipulating resource-use complementarity and
multi-trophic animal richness. We show that both mechanisms’ joint
contribution to positive diversity-productivity relationships generally
exceeds their individual effects, as both interactively create diverse
communities of complementary producer species. Specifically,
multi-trophic interactions in animal-rich ecosystems increase
complementarity the most when resource-use complementarity is low. The
interdependence of top-down and bottom-up forces in creating
biodiversity-productivity relationships highlights the importance to
adopt a more multi-trophic perspective on biodiversity-ecosystem
functioning relationships.

Trade-offs between multiple ecosystem services in UK and US salt marshes
Authors:   , Davidson Kate
Published: May 2021

Salt marshes supply vital ecosystem services (ES), providing material goods and recreation space, regulating natural hazards, and supporting diverse wildlife. However, increases in the utilisation of one ES can lead to reductions or ‘trade-offs’ in others. Because salt marshes are commonly used for grazing livestock, it is important to understand how this grazing impacts the saltmarsh ecosystem, and the consequences for ES supply. This thesis (i) uses a global meta-analysis to investigate the effects of livestock grazing on saltmarsh properties, and finds multiple significant changes to soil, vegetation and fauna properties. The meta-analysis reveals that the response of soil carbon is context dependent – there is no effect in Europe but a reduction in the Americas. (ii) Extensive surveys of soil carbon in grazed and ungrazed US marshes, controlling for key covariates, confirm that grazing trades-off against carbon storage in US marshes. These observational surveys, together with 18-month experimental exclusion of horses from a salt marsh in Georgia, show that grazing also disrupts the plant community in US marshes, but has little effect on resident invertebrates. (iii) Focussing on bees in salt marshes, a three-year study in south Wales, UK shows that grazing trades-off against bee habitat by reducing the flower cover of two key food plants, and that increases in plant diversity with grazing do not compensate for this negative effect. (iv) Spatial analyses of seven saltmarsh ES supplied by an estuary complex in south Wales show that marshes are not achieving their potential as a bee habitat here, due to the predominance of grazing. These analyses also show that the provision of ES by salt marshes is spatially heterogeneous, dependent on management, size and location. As a whole, this thesis adds to the understanding of grazer impacts and ES trade-offs, and supplies crucial data to support evidence-based management of salt marshes.
The New Requirement for Instructor Recruitment at School of Foreign Languages: What Do Administrators Think?
Authors: Aksoy Erdem , Bozdoğan Derya , Şen Mümin
Published: May 2021

In 2018, a legislative change -law number 2547- resulted in the adoption of the title "instructor", replacing "lecturers, specialists, translators, and education planners" for positions at the different departments of universities. This law also led to an adjustment in the instructor recruitment requirements. Correspondingly, the English language teaching instructors must have completed a master's degree to be hired to work at School of Foreign Languages (SFLs). This paper aims to uncover the opinions and suggestions of School of Foreign Language administrators about this change. This study shows that administrators approach the new requirement unenthusiastically due to the possible problems in hiring instructors. As an alternative criterion to a master's degree in ELT, administrators consider certification, teaching experience and graduate degrees in non-ELT programs. The results suggest that instructors be provided with professional development opportunities that merges theory into practice.

Authors: Latos Agnieszka
Published: May 2021

Nonostante la proliferazione di ministre e deputate sulla stampa italiana, il sistema linguistico continua a oscillare fra la norma e l’uso: alcune forme risultano plausibili, diventando sempre più frequenti, altre, seppur grammaticalmente consentite, non godono della stessa fortuna. Attraverso la ricerca su diversi dati disponibili in rete e l’interrogazione diretta dei parlanti nativi, questo studio empirico intende “fotografare” la situazione attuale concernente l’uso degli agentivi femminili in italiano, tenendo conto dei bisogni comunicativi, preferenze e sensibilità dei parlanti che devono confrontarsi con i cambiamenti linguistici in corso.Czy minister jest nadal w ciąży? Norma, użycie i użytkownik językaFormy żeńskie takie jak ministra (minister.F) czy deputata (posłanka) mnożą się w prasie włoskiej. Mimo to włoski system językowy nadal oscyluje między normą i użyciem. Niektóre nazwy nie wydają się problematyczne, a ich użycie wzrasta; inne natomiast, choć gramatycznie poprawne, nie cieszą się popularnością. W analizie wykorzystano różnorodne dane pochodzące z sieci internetowej oraz informacje i opinie uzyskane od rodzimych użytkowników języka. Głównym celem tego empirycznego studium jest „sfotografowanie” aktualnej sytuacji dotyczącej użycia żeńskich nazw wykonawców czynności w języku włoskim, ze szczególnym uwzględnieniem zagadnienia świadomości językowej, potrzeb komunikacyjnych oraz preferencji użytkowników języka, którzy codziennie konfrontują się z zachodzącymi w słownictwie zmianami.

Purpose. To estimate the frequency of tearing in patients after high-dose radioiodine therapy. Materials and Methods. The survey was conducted in 500 patients after radioiodine therapy (group 1) and 654 volunteers (group 2). We asked whether the respondent noticed epiphora last month, in case of a positive answer we specified how many times during the day it was necessary to wipe the tear, comparing the result with Munk scale. Results. The patients of group 1 noticed tearing in 232 cases, the respondents of group 2 noticed it in 186 cases. Epiphora was more frequent in patients of group 1 (46 % of cases), rather than in volunteers of group 2 (27 % of cases). Excessive tearing was noticed in 8.8 % of patients of group 1 and 3.5 % of respondents of group 2. The difference was statistically significant. Conclusion. 8.8 % of patients complain about excessive tearing after high-dose radioiodine therapy, which is more frequent than in the general population. This may be related to secondary acquired nasolacrimal duct obstruction. Key words: epiphora, nasolacrimal duct obstruction, radioiodine therapy.

Purpose. To substantiate the efficacy and safety of scleral collagen cross-linking with riboflavin and ultraviolet radiation. Material and methods. The study was conducted on cadaver porcine eyes and rabbit eyes. Results. It has been experimentally proven that crosslinking with riboflavin / ultraviolet A leads to an increase in the biomechanical strength of the scleral tissue, changing its structure and leading to an increase in the packing density of collagen fibers and an increase in the diameter of collagen fibrils, which confirms the formation of additional cross-links between scleral macromolecules. The absence of any pathological changes in the fibers of the fibrous membrane of the eye was established. The permeability of scleral tissue for ultraviolet radiation of the A range was determined. Based on the data obtained, a formula was proposed for calculating the threshold value of the intensity of ultraviolet radiation during the SCXL procedure. Using the methods of light microscopy, electroretinography and optical coherence tomography, it was revealed that SCXL with riboflavin / ultraviolet A under the studied parameters is safe for the structures of the eye (cornea, retina and optic nerve). A gentle technology for photopolymerization of the sclera with the use of the “UFalink S” device has been developed, the advantage of which is the ability to carry out ultraviolet irradiation in hard-to-reach areas of the eyeball. At the same time, an effective increase in the biomechanical strength characteristics of the scleral tissue was proved and the absence of a damaging effect on the structures of the eye was demonstrated. Conclusion. A clinical study of the scleral crosslinking procedure with riboflavin / ultraviolet A with the proposed parameters: irradiance of 3 mW / cm², irradiation time 30 minutes and preliminary saturation of the sclera with 0.1% aqueous solution of riboflavin for 20 minutes, which in experiments have shown their effectiveness and safety, is recommended. During the procedure, it is recommended to use a water-based photosensitizer riboflavin, without the addition of dextran, which leads to dehydration of the sclera and an increase in its permeability to ultraviolet light, which increases the risk of damage to the inner layers of the eye. Key words: scleral crosslinking, ultraviolet A, riboflavin, experiment, myopia.

Purpose. To find out the possibility of using angiotensin-converting enzyme (ACE) inhibitors included in calcium-phosphate nanoparticles (CFPs) to reduce intraocular pressure (IOP). Material and methods. Preparation of calcium-phosphate nanoparticles, introduction of ACEI in them, comparative evaluation of the action of enalaprilat, lisinopril and the beta-blocker timolol in the composition of CPF by determining their effect on intraocular pressure in rabbits. Results. Enalaprilat, lisinopril and the beta-blocker timolol in the composition of CPF statistically more significantly reduce intraocular pressure compared to simple solutions of these drugs. Conclusion. The introduction of drugs that reduce IOP into the CPF increases their bioavailability with the instillation method of administration, while their biological activity is preserved, and the effectiveness of the therapeutic effect increases.

THE NATURE OF TURBULENCE OF JETS OF STREAMS
Authors:   Private Enterprise “Data Center “Informmaterial”, Mishchenko Iurii
Published: May 2021

Understanding the nature of turbulence remains the most important unsolved problem of our time. Elucidation of the physics of the phenomenon is especially important. In this work, we propose a physical model of turbulence of jet streams. The model is based on the factors proven by practice that accompany the appearance of turbulence: flow velocity, size of the region, viscosity of the medium, and time scale. Theoretically, the conclusions are reduced to an analytical expression that determines the nature of the motion of the jets.
Terminological and Metrological Aspects in Siepser-Type Iris Suture Procedures

Instead of contemporary plethora, with tenths of different terms for only 7 elements, I suggest a system in which the main criterion is the length of the 2 filament ends just before the loop is externalized: L: long end, and S: short end. The name of the 2 corneal pathways, and 2 iris bites will rely on the name of the corresponding filament end that passes through, just before the loop is externalized: Sp/SP: short-end puncture/paracentesis, Lp/LP: long-end puncture/paracentesis, SIB: short-end iris bite, LIB: long-end iris bite. When the loop is externalized, the “intermediary segment”: (I) is created from L. The limits of (I) have been adjusted: instead of generally admitted limits from the middistance between SIB and LIB, to the middle of the externalized loop, I suggest that the S/(I) limit be situated at 1mm after the exit point of the loop from SP, and the (I)/L limit be situated at the re-entry point of the loop in SP. The suggested terminology and limits of (I) allow a clear and unequivocal description of techniques, simplify the repartition of functions per filament segment, avoid misunderstanding as cause of failure, facilitate the establishment of rules for success valid in any Siepser-type suture, and allow a new systematization of all iris suture procedures in a structure with a common stem, 2 branches (McCannel, Siepser) and leaves represented by technical variants.
