BACKGROUND

The world has been grappling with COVID-19 since December 2019, a dire public health crisis. Preventive and control measures are adopted to reduce the spread of COVID-19. To date, the public’s knowledge, attitudes, and practices (KAP) regarding COVID-19 across Bangladesh are poorly measured. Therefore, it is important to assess the KAP of people towards the disease and suggest appropriate strategies to combat COVID-19 effectively.

OBJECTIVE

This study aimed to assess the KAP of Bangladeshi people towards COVID-19 and determinants of those KAPs.

METHODS

We conducted a cross-sectional survey of 492 Bangladeshi people, based on purposive sampling technique, aged 18 years and above, from May 7 to 29, 2020, throughout the country. Both descriptive and inferential statistical analyses were performed. Wilcoxon Rank Sum Test and Kruskal-Wallis test were performed to test the statistical inferences across socio-demographic and economic information and knowledge, attitude, and practice scores separately. Spearman’s rank correlation test was performed to assess the correlation of scores between knowledge-attitude, knowledge-practice, and attitude-practice. Finally, multiple logistic regression analyses were conducted to identify the factors associated with KAP on COVID-19.

RESULTS

About 45% of respondents had good knowledge, about 49% of respondents expressed a positive attitude towards controlling COVID-19, about 74% of respondents had a favorable practice towards COVID-19. Almost three-fourths of the respondents went outside the home during the lockdown period. Our study found that the level of KAP varies significantly across different demographic and socioeconomic groups. Furthermore, the study found that good knowledge and attitude are significantly associated with COVID-19 health measures' better practice.

CONCLUSIONS

An evidence-informed and context-specific risk communication and community engagement, and a social and behavior change communication strategy against COVID-19 should be developed in Bangladesh, based on the findings of this study, targeting different socioeconomic groups.

Authors: Vestergaard Søren Viborg , Christiansen Christian Fynbo , Thomsen Reimar Wernich , Birn Henrik , Heide-Jørgensen Uffe
Published: March 2021

Background and objectives

Despite CKD consensus definitions, epidemiologic studies use multiple different algorithms to identify CKD. We aimed to elucidate if this affects the patient characteristics and the estimated prevalence and prognosis of CKD by applying six different algorithms to identify CKD in population-based medical databases and compare the cohorts.

Design, setting, participants, & measurements

Patients with CKD in Northern Denmark (2009–2016) were identified using six different algorithms: five were laboratory based defined by (1) one measured outpatient eGFR <60 ml/min per 1.73 m2 (single test, n=103,435), (2) two such findings ≥90 days apart (Kidney Disease Improving Global Outcomes, n=84,688), (3) two such findings ≥90 days apart with no eGFR >60 ml/min per 1.73 m2 observed in-between (Kidney Disease Improving Global Outcomes, persistent, n=68,994), (4) two such findings ≥90 and <365 days apart (Kidney Disease Improving Global Outcomes, time limited, n=75,031), and (5) two eGFRs <60 ml/min per 1.73 m2 or two urine albumin-creatinine ratios >30 mg/g ≥90 days apart (Kidney Disease Improving Global Outcomes, eGFR/albuminuria, n=100,957). The sixth included patients identified by reported in- and outpatient hospital International Classification of Diseases diagnoses of CKD (hospital-diagnosed, n=27,947). For each cohort, we estimated baseline eGFR, CKD prevalence, and 1-year mortality using the Kaplan–Meier method.

Results

The five different laboratory-based algorithms resulted in large differences in the estimated prevalence of CKD from 4637–8327 per 100,000 population. In contrast, 1-year mortality varied only slightly (7%–9%). Baseline eGFR levels at diagnosis were comparable (53–56 ml/min per 1.73 m2), whereas median time since first recorded eGFR <60 ml/min per 1.73 m2 varied from 0 months (single-test) to 17 months (Kidney Disease Improving Global Outcomes, persistent). The hospital-diagnosed algorithm yielded markedly lower CKD prevalence (775 per 100,000 population), a lower baseline eGFR (47 ml/min per 1.73 m2), longer time since first eGFR <60 ml/min per 1.73 m2 (median 70 months), and much higher 1-year mortality (22%).

Conclusions

Population prevalence of CKD identified in medical databases greatly depends on the applied algorithm to define CKD. Despite these differences, laboratory-based algorithms produce cohorts with similar prognosis.

Divisão fisiográfica da bacia do rio Buranhém como subsídio para o planejamento e gestão dos recursos hídricos
Authors: Silva Gabriela Mateus de Fontes , Reis do Nascimento Lopes Elfany , Berton Zanchi Fabrício , Batista Lopes da Silva João
Published: March 2021

A análise fisiográfica das bacias hidrográficas e a sua caracterização são ferramentas para a gestão destes territórios. O estudo objetivou avaliar estas características para a bacia hidrográfica do rio Buranhém, no Sul da Bahia, ponderando-as como fatores de impacto ambiental de modo a compartimentalizar a bacia. Realizou-se o processamento do Modelo Digital de Elevação (MDE) e da cobertura do solo cedidos pelo Fórum Florestal do Extremo Sul da Bahia utilizando o software QGIS 2.18. Também foram analisados os dados hidrometeorológicos, de vazão e precipitação disponíveis na rede nacional (Hidroweb/ANA). Os dados foram avaliados por sub-bacia, atribuindo pesos de acordo com o efeito de transmissibilidade superficial da água e concentração do deflúvio, descritos na literatura. Observou-se que bacias alongadas, com baixa cobertura vegetal e relevo acentuado podem ter tendência a inundações devido ao escoamento superficial favorecido, o que resulta em riscos de erosão, perda de solo, assoreamento, comprometimento da qualidade da água e baixa disponibilidade de água ao longo do tempo. A fisiografia se deu com a compartimentalização em quatro sub-bacias de contribuição de acordo com o potencial de impacto nos recursos hídricos, servindo de apoio para a gestão da bacia como território heterogêneo com diferentes tendências naturais e antrópicas.
Impactos de usinas hidrelétricas sobre os recursos pesqueiros amazônicos: os casos de Tucuruí e Belo Monte
Authors: Das Neves Barros Kaio Diego , Brabo Marcos Ferreira , Ferreira Antônio Carvalho
Published: March 2021

As usinas hidrelétricas (UHE) produzem parcela significativa da energia elétrica consumida no Brasil e espera-se aumentar o número desses empreendimentos para atender à crescente demanda. Contudo, a severidade dos impactos sobre a biodiversidade e à população nativa pode inviabilizar seu custo-benefício. O maior potencial brasileiro para aproveitamento hidroelétrico está na Amazônia, bioma onde a atividade pesqueira apresenta um relevante papel na socioeconomia, na produção de alimento e na geração de atividade remunerada. Neste contexto, a UHE de Tucuruí e, mais recentemente, a UHE de Belo Monte são experiências emblemáticas de alterações significativas na dinâmica da atividade pesqueira e dos estoques. Assim, podem balizar a mitigação de impactos por meio da definição de compensações e o estabelecimento de condicionantes para licenças ambientais de empreendimentos futuros e até aos já instalados, além de nortear a elaboração de planos de manejo para unidades de conservação. Este estudo realizou levantamento dos impactos resultantes da construção das UHE de Tucuruí e Belo Monte sobre os recursos pesqueiros em sua área de influência. Em Tucuruí, os efeitos foram sintetizados a partir de mais de 30 anos de informações disponíveis, enquanto que em Belo Monte enfatizou-se as exigências em termos de condicionantes e compensações do processo de licenciamento ambiental.
Radial diffusion model for fragrance materials: prediction and validation
Authors: Almeida Rafael , Rodrigues Alirio , Vargas Rubem , Cassel Eduardo
Published: March 2021

A predictive model based on Fick’s second law for radial diffusion is
proposed and validated for modeling the diffusion of fragrances. A pure
component, two binary systems, and a ternary system were used for
validation. The model combines the prediction model to represent the
liquid phase non-idealities, using the UNIFAC group contribution method,
with the Fickian radial diffusion approach. The experimental headspace
concentrations were measured in a diffusion chamber using the
solid-phase microextraction (SPME) technique and quantified using gas
chromatography with a flame ionization detector (GC-FID). The numerical
solutions were obtained along with an analytical model considering
constant surface concentration. The odor intensities of the studied
systems were calculated using Stevens’ power law and the strongest
component model, respectively. The numerical simulation presented good
adherence to the experimental gas concentration data. The proposed
methodology is an efficient and validated tool to assess the radial
diffusion of fragrance and volatile systems.
Phosphorylation in the accessory domain of yeast histone chaperone protein 1 exposes the nuclear export signal sequence
Authors: Ashida Sho , Morita Rikuri , Shigeta Yasuteru , Harada Ryuhei
Published: March 2021

Histone is a scaffold protein that constitutes nucleosomes with DNA in
the cell nucleus. When forming histone, hetero octamer is assisted by
histone chaperone proteins. As a histone chaperone protein, the crystal
structure of yeast nucleosome assembly protein (yNap1) has been
determined. For yNap1, a nuclear export signal/sequence (NES) has been
identified as a part of the long -helix. Experimental evidence via
mutagenesis on budding yeast suggests the NES is necessary for transport
out from the cell nucleus. However, the NES is masked by a region
defined as an accessory domain (AD). In addition, the role of the AD in
nuclear transport has not been elucidated yet. To address the role of
the AD, we focused on phosphorylation in the AD because proteome
experiments have identified multiple phosphorylation sites of yNap1. To
computationally treat phosphorylation, we performed all-atom molecular
dynamics (MD) simulations for a set of non-phosphorylated and
phosphorylated yNap1 (Nap1-nonP and Nap1-P). As an analysis, we
addressed how the NES is exposed to the protein surface by measuring its
solvent-access surface area (SASA). As a result, there was a difference
in the SASA distributions between both systems. Quantitatively, the
median of the SASA distribution of Nap1-P was greater than that of
Nap1-nonP, meaning that phosphorylation in the AD exposed to the NES,
resulting in increasing its accessibility. In conclusion, yNap1 might
modulate the accessibility of the NES by dislocating the AD through
phosphorylation.

Charitable Contribution Matching and Effort-Elicitation
Authors: Douthit Jeremy D. , Martin Patrick R. , McAllister Michelle
Published: March 2021

We examine the effect of a charitable contribution matching (CCM) program on employee effort. In CCM programs, employers commit to match employees' donations to charity. We expect CCM to activate a norm of other-regarding behavior, inducing employees to increase effort to benefit their employer. Experimental results robustly support our expectation. We find that CCM increases effort under both fixed-wage and performance-based incentive contracts. Further, our results suggest that CCM is more effective at eliciting effort than alternative uses of firm capital. Specifically, CCM is more effective at eliciting effort than the firm allocating an equivalent amount of capital to either direct firm charitable giving or increased performance-based pay. Our study suggests that CCM has efficient and robust effort-elicitation benefits that increase its value as a compensation tool incremental to any initial employee selection benefits from CCM and any effort benefits from firms' direct charitable giving.
Political Bias in the Media's Coverage of Firms' Earnings Announcements
Authors: Rees Lynn , Twedt Brady J.
Published: March 2021

This study examines whether firms' political activism induces bias in the media coverage of earnings announcements and how such coverage impacts markets. We infer firm political ideology based on employee political contributions and identify firm and manager characteristics associated with distinct ideologies. We find that media outlets negatively slant their coverage of earnings announcements when the political leanings of the outlet are incongruent with the political ideology of the firm. Consistent with slanted coverage affecting market outcomes, we provide evidence that the price reaction to good (bad) earnings news is decreasing (increasing) in the percent of incongruent media outlets covering the earnings announcement. In addition, trading volume and returns volatility are decreasing for good earnings news with the percent of incongruent media outlets. Our results suggest that the prevalent bias across some media outlets in their coverage of political news also affects their coverage of corporate financial events.

Authors: Astuti Suryani Titi , Sulandari Sri , Hartono Sedyo , Somowiyarjo Susamto
Published: March 2021

Yellow mosaic stunt disease was found at some nurseries of Petunia in Sleman, Yogyakarta, also in Muntilan and Magelang Central Java. The disease was very important due to its ability reducing the quality and quantity of Petunia seedlings. The causal agent of the disease may be carried over to imported seeds and necessary to identify as a basic information for developing control strategies. This research was done by mechanical transmission on indicator plants. The observation of the causal agents was conducted using electron microscope with quick dipping method and the molecular detection was done using nested PCR with TobRT up1-TobRT do2 as the external primers and TobN up3-TobN do4 as the internal primers. Mechanical inoculation showed chlorosis symptoms that developed into local spot on Chenopodium amaranticolor as well as mosaic and vein banding on Nicotiana benthamiana. The observation using electron microscope showed rod-shaped virus particles sized approximately 300 nm and by PCR method produced around 568 bp and 400 bp DNA band. Based on the sequence analysis, the disease was caused by Rehmania mosaic virus. This type of Tobamovirus has 96% similarity with ReMV-Japan. ReMV, a plant pathogen which was a member of Tobamovirus that has never been reported in Indonesia. This research was the first report of ReMV in Indonesia infecting Petunia as ornamental plant.

Growth, mortality and exploitation rate of Selene dorsalis (Gill, 1863) from the continental shelf of Ghana (West Africa) were examined between July 2018 and June 2019. The study provided results on fishery dynamics parameters needed to estimate the stock status and characteristics of S. dorsalis in the coast of Ghana. Monthly length-frequency data were collected from 629 samples and analysed using fisheries models fitted in TropFishR package in R software. The von Bertalanffy growth parameters were utilised to analyse the population dynamics of the species using ELEFAN Simulating Annealing. Based on the estimates, the asymptotic total length (L∞) was 22.2 cm, the coefficient of growth (K) was 0.76 year-1, and the calculated growth performance index (phi) was 2.58 with Rn value of 0.55. The total mortality rate (Z) was 3.32 year-1 with a natural mortality rate (M) of 1.21 year-1 and fishing mortality rate (F) of 2.11 year-1. The exploitation rate (E) estimated for the species was above the optimum level of 0.5, which indicates that S. dorsalis is overexploited in the coast of Ghana. It can be concluded that the exploitation rate of S. dorsalis has exceeded the optimum limit, hence the need for enforcement and improvement of fisheries management measures such as mesh size regulations, capping of canoes, closed fishing seasons and compliance with fisheries policies.

In designing the receiving-transmitting active phased antenna array (APAA) an important problem is an achievement of the level of maximum outcome between the receiving and transmitting channels. In the work, the concept of building multi-beam receiving-transmitting antenna systems based on APAA has been considered. The criteria for selecting the type of emitter for an S-band antenna with the specified parameters have been presented. It has been shown that the use of a turnstile emitter based on the printing technology can reduce the complexity of manufacturing without compromising the technical parameters. In accordance with the requirements for volume of the tasks of APAA being designed the optimal geometric and electric characteristics of the turnstile radiator have been calculated. In designing the radiating apertures of the multi-element APAA the specifics of the dependence of their electric characteristics on the inter-element distance has been taken into consideration. To increase the circular polarization coefficient of the apertures being designed, the method of tearing apart of the radiator with further compensation of the obtained phase using the phase rotators APAA has been implemented. The estimates of the energy characteristics of the multi-element antennas with a given scanning sector for various inter-element distances have been given. To ensure the separation of the receiving and transmitting antennas the recommendations have been presented.

Authors:   Siberian branch  of the Russian Academy of Sciences, Fedotova Natalia Dmitrievna
Published: March 2021

The study deals with the development of school education in the republic of Sakha (Yakutia) in the context of its accessibility or inaccessibility. The reforms taking place in this area, including those related to the education infrastructure in the context of demographic processes, are ambiguous. Based on the analysis of statistical information, official sources, the specifics of the development of the educational environment of the region in dynamics over several years are characterized. Most of the general education organizations are located in rural areas. In the period between 2000 and 2019, there was a decrease in the number of secondary educational institutions, while this process was uneven in relation to urban and rural settlements. Factors influencing the availability of education include intra-republican migration processes, a decrease in the number of general education organizations, the small number of schools in rural areas, and a high load on secondary educational institutions in cities. It is concluded that the availability or unavailability of school education is due to the place of residence of citizens.

The search for new effective methods of teaching Russian as a foreign language does not lose its relevance. The authors of the article offer case studies developed on the basis of national and regional material, taking into account the interests and needs of foreign students studying at a regional University. They are designed for international students on the topics of climate, food, clothing, and entertainment in the Sakha Republic. Each task is provided with a detailed cultural commentary on the culture and traditions of the Yakut people, as well as post-text creative tasks based on the principle of "dialogue of cultures". Finally, the author concludes that it is advisable to use cases based on regional material in teaching the Russian language, which contribute to the formation of communicative and linguistic-socio-cultural competencies of foreign students.
Language Code as a Factor in Educational Inequality of Children From Working Class Families
Authors:   Tyumen Industrial University, Karnaukhov Igor Aleksandrovich , Shirshova Viktoria Viktorovna ,   Tyumen State Secondary School № 15
Published: March 2021

Language is not just a means of communication between individuals in society, but also a marker of a social class. School forms a child's personality, including the development of his speech abilities and communication skills regardless of social stratification. However, in practice there are cases of educational inequality between children from working and middle class families. The study aims to analyze the impact of the social and linguistic environment on the school performance of children from working class families in their dialectical interaction. The authors of the study suggest that one of the factors leading to educational inequality in relation to children of the working class is the language code used by representatives of society in a restricted or expanded form. A conflict arises between language systems: the code used by children in everyday communication contradicts the extended code that is required for learning. To solve the problem, it is necessary not only to use an integrated approach, that involves supporting both the child and the family as a whole, but also to transform the methodological approaches to learning in general.
Digital Technologies as a Factor for Forming the Competencies of a Modern Employee
Authors:   Bauman Moscow State Technical University, Subocheva Oksana Nikolayevna , Yakovleva Yekaterina Aleksandrovna ,   National Research University
Published: March 2021

The paper reviews the issues of changing the content and conditions of work under the influence of digital technologies. Based on the analysis of data from secondary sources, the ambiguous nature of the effects of the information technology revolution is revealed: the emergence of digital inequality, the lack of diversity, the alienation of a person in production from society, impersonal and manipulative communication, and a utilitarian-pragmatic approach to the worker, and others. It is concluded that it is necessary to take into account the humanistic component in the era of digital changes in order to weaken the situation of uncertainty and risk characteristic of society in the period of transformation. It examines how the introduction of digital technologies is changing the composition of the competencies of a modern employee. The attention is drawn to the difficulties of creating a universal model of the qualities and properties of an employee of the digital age. The model of competences, which consists of three “universal” groups, is considered as the preferred one: skills in working with digital technologies; thinking and behavior necessary to achieve success in the digital economy, including so-called “soft” interpersonal and intercultural communication skills and professionally oriented skills. The composition of competencies changes depending on the direction of the organization and its involvement in the digitalization process.

El presente artículo indaga las representaciones sociales de los funcionarios del Poder Judicial del AMBA respecto de las migraciones externas (europeas y sudamericanas). El escrito se aproxima a la comprensión de las relaciones interculturales a través de la voz institucional de los funcionarios comparando las representaciones que poseen respecto de las migraciones europeas y sudamericanas según su idiosincrasia y significatividad histórica. Los principales hallazgos indican que las representaciones de los funcionarios respecto de estos colectivos son fuertemente diferenciadas. A las migraciones europeas se les asignan características positivas relacionadas a la construcción de la nación y su identidad debido a la cultura del trabajo y valores civilizados mientras que a las migraciones sudamericanas, se le atribuyen cualidades negativas, atravesadas por el aprovechamiento, el delito y el arraigo a sus propias culturas. De esta manera, el artículo demuestra que la interculturalidad en la República Argentina, reviste conflictividad y antagonismo y que por lo tanto, las relaciones entre nativos y migrantes se constituyen como relaciones de dominación. La metodología de la investigación es cualitativa, y la técnica de investigación es la entrevista, individual y semi-estructurada. Los datos fueron codificados y analizados de acuerdo a los pilares de la Teoría Fundamentada.
Overtourism

Numerosos estudios analizan la compleja sostenibilidad de determinados modelos de turismo masivo, cada vez más cuestionados. Paralelamente la ciudadanía, mediante grupos y organizaciones, incrementa sus posicionamientos públicos ante lo que le parece insatisfactorio. Este artículo pretende avanzar en el análisis de procesos y acciones ciudadanas que se oponen al turismo. Describe las distintas manifestaciones ciudadanas de una crisis de rechazo a la saturación turística en Barcelona (verano de 2017), establece las cuatro fases de esta crisis y analiza las modalidades de las acciones comunicativas de las organizaciones implicadas. Mediante la observación directa y técnicas cualitativas aborda los sucesos que ocurrieron en el espacio público (material y virtual) y valora las acciones comunicativas lideradas por los principales actores de esas protestas ciudadanas. El análisis descriptivo e interpretativo pretende así contribuir a la apertura del campo de estudio de este fenómeno social conocido como overtourism o turismofobia y permite definir futuras líneas de investigación.
Discursos mediáticos sobre derechos de migrantes, desde los DDHH
Authors: Gottero Laura Angelica
Published: March 2021

El artículo focaliza en las posibilidades metodológicas de las ciencias de la comunicación para estudiar el acceso a derechos para personas migrantes tematizado en los discursos mediáticos, pues esta construcción simbólica incide en sus posibilidades concretas de protección y respeto en las sociedades donde se encuentran.

La finalidad de esta investigación es aportar razonamientos e insumos para pensar un modelo de comunicación con base en el enfoque de derechos que permita proteger y reconocer el acceso a derechos de personas migrantes no sólo en el contexto de los discursos mediáticos, sino en el plano donde éstos inciden de manera clara: las prácticas sociales en sus diversas expresiones.
Origen y construcción de identidad(es)
Authors: Saavedra Maria Natalia
Published: March 2021

El presente artículo es resultado de la investigación doctoral denominada “Origen y construcción de identidades en el “barrio” Gauchito Gil de Salta (2009-2017). Constitución de prácticas y representaciones sociales en procesos de apropiaciones territoriales”. La misma se centró en el barrio Gauchito Gil, de la zona sudeste de la ciudad de Salta, Argentina. Se tomó como período de análisis desde su origen como “asentamiento” en el año 2009 hasta el 2017 dando cuenta de su proceso de edificación como “barrio”. Se propuso comprender cómo diversos actores sociales subalternos de Salta deciden unirse y ocupar un territorio. Esto mediante el análisis de los modos de territorializar de los vecinos junto con las formas de construir representaciones sociales, lo cual incide directamente con la conformación de las identidades siempre disímiles pero que lo cohesionan como colectivo. Se pretendió que el trabajo sea un aporte para comprender los nuevos procesos urbanos que se han venido reconfigurando en la ciudad desde la década de 1990 y hasta la actualidad. Y a la vez, que se colabore en el estudio de temáticas referidas a representaciones sociales, identidades, territorialidades, que se entraman en procesos comunicacionales actuales y locales.
La interdisciplina y alternativas comunicacionales
Authors: Navarro Nicoletti Felipe
Published: March 2021

En dicho trabajo buscaremos retomar movimientos interdisicplinares que nos permitan reflexionar, por un lado, la estructura interna de la Comunicación Social; y por otro lado, investigaciones y observaciones que rompan con la estructura rígida de las disciplinas para ahondar en otras variables. Para el caso específico de la comunicación, tomamos las categorías de «popular», «alternativo» y «comunitario» para poner en primer plano variables que demuestren la necesidad de establecer perspectivas interdisciplinares a la hora de observar objetos insertos en entramados de la sociedad moderna.
Y el mundo las abrazó. En torno a los viajes al exterior de las Madres de Plaza de Mayo
Authors: Zubillaga Paula
Published: March 2021

Reseña de la obra dividida en dos tomos El mundo es un pañuelo. Viajes al exterior de las Madres de Plaza de Mayo, publicada por la Editorial de la Universidad Nacional de La Plata en noviembre de 2018 y coordinada por Luis Zarranz. El primer tomo abarca los viajes emprendidos entre los años 1978 y 1990, mientras que el segundo los realizados entre 1991 y 1997. Leída en su conjunto y dado el material de archivo utilizado, la obra es muy valiosa al menos en dos aspectos. Por un lado, permite sistematizar la conformación de distintas organizaciones en el exterior que se constituyeron en Grupos de Apoyo a las Madres de Plaza de Mayo, lo que nos aproxima al impacto de la Asociación fuera de las fronteras argentinas. Por otro lado, -aunque no se lo propone-, permite ahondar en la relación, tan poco estudiada, entre la Asociación y sus filiales, obteniendo una pequeña aproximación al impacto de la Asociación dentro del país.
Sensitivity and specificity of using pelvic ultrasonographic parameters combined with basal gonadotropin levels to diagnose central precocious puberty in Thai girls

Background

The criterion standard gonadotropin-releasing hormone (GnRH) stimulation tests to diagnose central precocious puberty (CPP) are time-consuming, inconvenient, and expensive.

Objectives

To determine predictive cut-off values codetermined by ultrasonographic parameters and basal gonadotropin levels in girls with premature sexual development and compare them results of criterion standard tests in a study of diagnostic accuracy.

Methods

Retrospective review of hormonal investigations and ultrasonographic uterine and ovarian parameters in a consecutive sample of girls at a single center, tertiary care hospital in Bangkok, Thailand.

Results

We separated data from 68 girls (age range 2–12 years) into 2 groups based on their response to a GnRH analogue agonist stimulation test. A “prepubertal response” group included girls with premature thelarche and thelarche variants (n = 18, 6.37 ± 1.77 years) and a “pubertal response” group, including girls with CPP (n = 50, 8.46 ± 1.46 years); excluding patients with pathological causes (n = 0). The basal level of luteinizing hormone (LH) had the largest area under receiver operating characteristic curves (AUC) of 0.84; 95% confidence interval [CI] 0.74–0.93) compared with basal levels of follicle stimulating hormone (AUC 0.77; 95% CI 0.64–0.90) or estradiol (0.70; 95% CI 0.56–0.85). An optimal cut-off of 0.25 IU/L LH was related to a pubertal response to GnRH analogue agonist stimulation tests with 75.0% sensitivity, 88.9% specificity, 94.7% positive predictive value (PPV), and 57.1% negative predictive value. Uterine and ovarian cut-off volumes of 3.5 cm3 and 1.5 cm3 were related to a pubertal response with 88.6% and 76.2% PPV, respectively. A uterine width cut-off of 1.7 cm combined with a basal LH cut-off of 0.25 IU/L increased specificity and PPV to 100%.

Conclusion

Combining uterine and ovarian ultrasonographic parameters with basal gonadotropin levels, especially uterine width and basal LH level, appears useful for diagnosis of CPP.

Primulic acid 1 is the main saponin present in Primula elatior. The present study describes the isolation of this amphiphilic compound from primula root. It was performed by ultrasonic maceration, reverse-phase column chromatography and crystallization. Investigations of its physicochemical property are represented by the determination of critical micelle concentration (cmc). The cmc value of the amphiphile was 9.4 × 10−5 mol·dm−3. The evaluation of environmental toxicity was performed on a daphnid species Simpocephalus expinosus s.l., which was very sensitive to primulic acids 1. The results from acute immobilisation test show that the tested compound has half maximal effective concentration after 24 hours (EC50-24 h) equal to 6.9 mg·l−1. Saponin can be classified as a toxic compound for aquatic organisms.
Evaluation Method of Traffic Safety Maintenance of High-Grade Highway
Authors: Wang Ying , Chen Yanfei
Published: March 2021

With the evolution of better highway services and larger traffic volume, the traditional maintenance management indicators can no longer satisfy the demands of highway traffic safety. In order to ensure timely, fast, safe, and reliable highway maintenance and repair, this paper proposes a road traffic safety maintenance evaluation method. The fuzzy maintenance evaluation method based on the gray correlation degree is used to construct the safety maintenance evaluation model. The damaged characteristics of the high-grade highway components are analysed. The parameters of the evaluation model are established using the analytic hierarchy process, and the accuracy of the model is verified through experiments. The results show that the safety service level can intuitively measure the maintenance and repair status of various transportation facilities. When the safety level is 1 (above 87 points) or 2 (above 85 points), the road maintenance and repair are in good condition and the road users have a high level of satisfaction on safety; when the safety level is 3 or 4 (80 points or less), it reflects that there are weak links in the road components, and targeted maintenance repairs are required. The results provide references for highway safety maintenance decision-making and improvement of highway traffic safety services to some extent.
