Authors: Rumbayan Hendra Kundrad Susanto , Musrifin  , Sijono  , Faty M Qiber Azim
Published: March 2023

Based on its geographical position, Pasarwajo District has regional boundaries, namely: Kapontori District, Wolowa District, Wabula District, South Buton Regency, Flores Sea and BauBau City. Kondowa Village is one of the villages in Pasarwajo District whose population is mostly transmigration. The area of Pasarwajo District is 3.77 KM2. Kondowa Village only has 1 access road to connect with Holimombo Jaya Village so the community took the initiative to build a new road that will be an alternative route to go to the opposite village. The results of the debate resulted in the design of the Kondowa Village Road and the materials that will be used for the construction of the village road which is then agreed upon with the length of the road to be worked on, which is 2,715 meters long. The Kondowa Village Government hopes to collaborate with the Civil Engineering Study Program, Faculty of Engineering, University of Muhammadiyah Buton to continue helping design planning in the building industry.

Barriers to sustainable development in the fashion industry: Supply chain complexity and consumers' attitude-behavior gap
Authors: Starčević Slađana , Marinković Veljko , Vjetrov Ana
Published: March 2023

Sustainability has become the world's megatrend. Many companies are under pressure from governments and the public to implement sustainable business practices. Unlike the food industry, where demand for sustainable products is relatively easy to achieve because food directly affects the health of consumers, in the fashion industry this is not the case. The aim of the paper is to analyze barriers in the development of a sustainable fashion industry, including: the complexity of establishing a sustainable supply chain, unclear certification and labeling system, high prices of sustainable fashion products, the high growth rate of the fast fashion industry, low consumer awareness of the importance of sustainability in the fashion industry which leads to a gap between consumer attitudes and buying behavior, and low demand for sustainable fashion products. In addition, sustainable fashion is a contradictory term. The whole point of fashion is a change of styles from season to season, which in turn accelerates purchases. This is contrary to the concept of sustainable fashion, which implies a slowdown in consumption. Meta-analysis was used as the main research method in this paper to integrate the findings of many studies and direct prospective research.
Exposure of the students of the secondary school of electrical engineering "Nikola Tesla" to wireless electromagnetic radiation
Authors: Jevtić Radoje , Janković Ivana
Published: March 2023

Introduction/Aim: Wireless electromagnetic radiation from routers is an everyday occurrence in the life and work of modern man. They are widely used in many professional, public and domestic facilities, which means that people of all ages can be constantly exposed to electromagnetic radiation from these devices. The aim of this study was to determine the electric field strength, the magnetic field strength, and the electromagnetic exposure of students in different laboratories of the Secondary School "Nikola Tesla", depending on the type of routers installed in them, as well as to check some of the obtained results with the help of the appropriate software program of high-frequency (High-Frequency Simulation Software - HFFSS) for the simulation of electromagnetic radiation through different environments. Methods: Measurements of electric and magnetic field strength, as well as electromagnetic exposure, were carried out using the measuring instrument Spectran HF 60105, on four different types of routers installed in four laboratories of the Secondary School of Electrical Engineering "Nikola Tesla" in Niš. Measurements were realized on each router, through five horizontal and five vertical positions, with a distance of 45o in relation to the horizontal and normal axis of the router, and with spaces of 1 cm, which gives a total number of one thousand measurements. Results: The measured results obtained on four different routers that operated at a frequency of 2.4 GHz for the electric field strength (measured in millivolts per meter), magnetic field strength (measured in microampere per meter) and electromagnetic exposure (in microWatts per square centimeter) were below the limit values defined by standards. The achieved results were verified only for the router TL-WR841HP with the help of HFSS for the simulation of electromagnetic radiation through different environments. The result of the simulation check practically confirms the reliability of the measured results for TL-WR841HP router. Conclusion: Measuring and monitoring electromagnetic radiation is a very important task aimed at preserving and improving the quality of the working and living environment, as well as the quality of life and health of people and children. Software programs for the simulation of electromagnetic radiation can be used when it is not possible to carry out experimental measurements due to technical problems, hindered access to the device, danger of excessive radiation or some other reasons.
Knowledge, attitudes and behavior of students of the Medical College of Applied Sciences in Belgrade related to the significance of HPV infection, the HPV vaccine and other preventive measures
Authors: Dabić Marijana
Published: March 2023

Introduction/Aim: Knowledge and awareness of the importance of the HPV vaccine against human papillomavirus (HPV) can greatly contribute to the reduction of cervical cancer and other malignant tumors. The aim of this study is to assess the knowledge, attitudes and behavior of students about HPV infection, as well as to propose measures for the better coverage of young people with the HPV vaccine. Methods: A cross-sectional study included 449 students of healthcare of the Medical College of Applied Sciences in Belgrade in the period from March to May, 2019. Data were collected using a questionnaire. Chi-square test and Fisher's exact tests were used for the statistical analysis of data. Results: The average age of students was 21.02 ± 2.59 years. 86.0% of students assessed their knowledge about the HPV vaccine as satisfactory. Teachers had the greatest influence on their knowledge about the HPV vaccine (79.7%), followed by the electronic media (10.7%). Medical platforms for information about the HPV vaccine were used by only 9% of students. Students acquired the first information and a certain degree of knowledge about HPV infection and the HPV vaccine in high school (80.4% and 65.6%). Only 3.4% of students think that young people in Serbia are sufficiently informed about HPV infection and 0.4% about the HPV vaccine. Every second student believes that peer education in schools is one of the ways to better inform young people. About 94% of students know that there is an organized screening for cervical cancer in our country. Only 10.2% of students wanted to vaccinate their child with the HPV vaccine, and those who would not do so cite the insufficient information about the safety and effectiveness of the vaccine as their main argument (81.6%). Respondents who were for the HPV vaccine significantly less frequently underwent regular gynecological examinations. Conclusion: Students of the Medical College of Applied Sciences in Belgrade believe that there should be better education about HPV infection and the vaccine, which could be best realized by conducting peer education.
Post-exposure and pre-exposure prophylaxis as HIV preventive measures
Authors: Baroš Slađana , Grujičić Sandra
Published: March 2023

HIV chemoprophylaxis started to be used since the first AIDS drug was registered, i.e. in 1987. Postexposure prophylaxis (PEP), used by persons accidentally exposed to HIV, is mostly related to professional accidental exposure to HIV (mostly among healthcare workers). It is estimated that PEP decreases HIV risk by 81%. Research and implementation of pre-exposure prophylaxis (PrEP) started about 10 years ago. PrEP is intended for use among those who are HIV negative, and in the continuous HIV risk due to their behavior. It is estimated that PrEP use decreases HIV risk by 75% or more, depending on the population and adherence to treatment. In Serbia, PEP and PrEP are still not fully regulated. However, in 2022, the work on regulations has started. In countries with unregulated PrEP, there is a risk from informal therapy use without medical supervision, which can lead to the development of resistant HIV cases among those with previously undiagnosed HIV infection. Both interventions belong to the biomedical HIV preventive interventions, and both are relevant for reaching the global AIDS target - to end AIDS as a "public health threat" by 2030. Nevertheless, for biomedical interventions to be at maximum efficacy, they have to be integrated with adequate behavioral ones, aiming to increase information, adherence to the therapy, and to periodical medical supervision, in line with defined PEP and PrEP recommendations.

Authors: Campos Roger Francisco Ferreira de , Kuhn Daiane Cristine , Matias Caroline Aparecida , Reichardt Lecilda
Published: March 2023

A expansão da atividade turística e procura por atividades de lazer tem desencadeado a construção de novas áreas, causando alteração nas características espaciais originais. Os lagos artificiais são bastante procurados para pesca recreativa. Todavia, a sua construção sem um planejamento adequado pode comprometer a qualidade da água e causar problemas à saúde pública, com acúmulo de substâncias tóxicas na cadeia trófica, devendo manter a qualidade e a preservação de águas utilizadas para destinação recreativa. Portanto, o presente trabalho tem como objetivo de analisar a interação antrópica com a qualidade da água do Lago das Araucárias do município de Fraiburgo/SC. Foram coletadas amostras de água em cinco pontos amostrais no lago das Araucárias, localizado na região central de Fraiburgo, SC. Os parâmetros:  pH, temperatura, condutividade e oxigênio dissolvido foram aferidos in loco. As variáveis de demanda bioquímica de oxigênio, sólidos totais, sólidos dissolvidos, sólidos em suspensão, ortofosfato, fósforo total, nitrito, nitrato, amônia, dureza e alcalinidade foram avaliados conforme a metodologia descrita no Standard Methods for Examination of Water and Wastewater e os valores obtidos foram comparados com a Resolução CONAMA nº 357/2005 e Portaria 2.914/2011. Os parâmetros de pH, oxigênio dissolvido e fósforo total foram aqueles que não se enquadraram na legislação vigente, sendo os valores encontrados influenciados principalmente pela presença de matéria orgânica oriunda da liberação de efluentes domésticos e industriais. Assim, para o enquadramento à classe 3 para águas doces é de responsabilidade do poder público investir na minimização de despejo de efluentes domésticos para que o nível de fósforo total atenda ao fixado nas legislações vigentes.

As praças são a tipologia de áreas verdes predominantes nas cidades e exercem inúmeros benefícios ambientais. O ordenamento destes espaços os torna mais eficientes e facilitam sua gestão. O objetivo deste estudo foi estabelecer um método de avaliação de praças, na cidade de Marília – SP. O município encontra-se em importante região de abastecimento hídrico e necessita de áreas que favoreçam a infiltração de água no solo. O universo amostral foi de 113 praças distribuídas em 5 zonas (centro, norte, sul, leste e oeste). A amostragem foi aleatória estratificada, onde selecionou-se 28,32% das praças de cada zona. Estabeleceu-se 4 parâmetros para compor a avaliação das praças: área total (AT), área permeável (AP), densidade arbórea (DA) e cobertura arbórea (CA). Os dados foram coletados em campo, através da medição de copa e contagem de indivíduos arbóreos, e em laboratório, através do programa QGis 3.16.0., na obtenção da área total e área permeável. Após a obtenção dos valores, cada parâmetro foi dividido em 3 classes iguais, considerando os valores máximos e mínimos obtidos para cada um. Aos valores maiores, classificados como ‘bom’, atribuiu-se 3 pontos, aos valores médios, ou ‘regular’, atribuiu-se 2 pontos, e aos valores menores, ou ‘ruim’, atribuiu-se 1 ponto, gerando uma nota final para cada praça e uma média para cada zona. A praça ‘Joana Rodrigues dos Santos’ obteve nota superior (10) e atingiu valores máximos para AP, DA e CA, classificando-se como modelo a ser seguido. A praças ‘São Paulo’ e ‘Dr. Miguel Souza e Silva’ atingiram nota mínima (4) e necessitam de diversas intervenções. A zona norte foi a melhor classificada (7,67) e a zona central a pior classificada (5,25).

O uso dos recursos hídricos é um problema que a região do Nordeste do Brasil enfrenta devido a quantidade de água existente não ser suficiente para suprir a demanda populacional para a realização das atividades domésticas, industriais e principalmente agrícolas. O presente trabalho objetivou mapear e analisar a qualidade das águas das nascentes na comunidade de Piroás no município de Redenção- CE. O levantamento de dados sobre as nascentes existentes na comunidade Piroás foi obtido a partir da aplicação de 106 questionários que foram aplicados aos estudantes da Universidade da Integração Internacional da Lusofonia Afro-Brasileira (UNILAB), assim como para a comunidade em geral residente no município de Redenção no período de 06/09/2021 a 07/10/2021. O mapeamento das nascentes da comunidade Piroás foi realizado por caminhamento com auxílio de um GPS modelo Garmim 76scx. O Índice de Impacto Ambiental em Nascente constatou que as nascentes necessitam de intervenções imediatas para a revitalização das mesmas. As nascentes N1, N3, N4 e N5 se enquadram na classe ruim, enquanto que as N2 e N6 foram categorizadas na classe razoável de preservação. Portanto, é necessário que sejam desenvolvidas pesquisas que visem a conservação e proteção dessas nascentes para assegurar a revitalização e a sustentabilidade das nascentes ainda existentes na comunidade Piroás.
La comunidad canaria en Venezuela, un elemento clave en la política del archipiélago (1999-2010).
Authors: Luis León Ángel Dámaso
Published: March 2023

The migratory process that brought thousands of Canarians to Venezuela (1936-1980) did not completely break the ties of this community with their territory of origin. With the stabilization of Democracy in Spain and Autonomy in the archipelago, Canarians living in Latin America demanded their rights as citizens. The role of this community in its territory of origin will be analyzed in the following lines, emphasizing its participation in the political dynamics of the Canary Islands, and its ability to modify it, as well as the role that many members of said community played within the organic structure of the main political parties of the islands. To do this, a multitude of different historical sources will be addressed that will try to provide a clear and clear message about the level of influence of this community in the political reality of the Canary Islands.

El proceso migratorio que llevó a miles de canarios a Venezuela (1936-1980), no rompió del todo los vínculos de esta comunidad con su territorio de origen. Con la estabilización de la Democracia en España y de la Autonomía en el archipiélago, los canarios radicados en América Latina reclamaron sus derechos como ciudadanos. El papel de esta comunidad en su territorio de origen será analizado en las siguientes líneas, poniendo énfasis en su participación en la dinámica política de Canarias, y en su capacidad para modificarla, así como en el rol que muchos miembros de dicha comunidad jugaron dentro de la estructura orgánica de los principales partidos de las islas. Para ello, se abordarán multitud de fuentes distintas que intentarán aportar un mensaje nítido y claro sobre el nivel de influencia de esta comunidad en la realidad política de Canarias.

We raise in this research various questions about the geographic information provided by Humboldt on his trip to New Spain, influencing the data relating to the scope of the Internal Provinces and their cartographic developments, with the appropriate corrections in astronomical measurements and the situation of some key places; the additional details of hydrography and orography allowed the Prussian sage to outline his own maps on the Mexican Septentrion, in a commendable task, because due to the relative brevity of his stay in the viceroyalty the cartographic work was based (unlike in Venezuela) on the reading and correction of indirect references.

Planteamos en la presente investigación diversas cuestiones sobre la información geográfica proporcionada por Humboldt en su viaje a Nueva España, incidiendo en los datos relativos al ámbito de las Provincias Internas y sus desarrollos cartográficos, con las correcciones oportunas en mediciones astronómicas y la situación de algunos lugares claves; los detalles suplementarios de hidrografía y orografía permitieron al sabio prusiano perfilar sus propios mapas sobre el Septentrión mexicano, en una tarea encomiable, pues debido a la relativa brevedad de su estancia en el virreinato la labor cartográfica se basó (al contrario que en Venezuela) en la lectura y corrección de referencias indirectas.
La apuesta por el realismo en Chuquisaca iniciando el proceso de independencia. 1809-1812.
Authors: Zalles Cuestas Solange Leonor
Published: March 2023

Chuquisaca, located in the current territory of Bolivia, whose main city was La Plata. Its proximity to the Porco and Potosí mines would lead to its foundation. It housed the capital of the Royal Audience of Charcas and the Archbishopric and brought together the population from various places who came to make their requests or to study in schools and at the San Francisco Xavier University. When the news of the French invasion of the Peninsula arrived in 1808, this city swore allegiance and organized the first meeting of the territory. In this context of crisis, research has been developed that highlights the construction of the nation, therefore, this work aims to delve into the realists, the forgotten or those who were excluded from traditional histories. During the years 1809 to 1812, the local population showed, in its vast majority, its fidelity to the Crown, to maintain peace and stability. This analysis identifies specific times that demonstrate a commitment to realism, a political option exposed from various events and actions conducted when defending the king's flags and, to his privileges and assets endangered with the advance of the patriotic troops coming from Buenos Aires since 1810.

Chuquisaca, situada en el actual territorio de Bolivia, cuya ciudad principal fue La Plata. Su cercanía a las minas de Porco y Potosí provocaría su fundación. Albergó a la capital de Real Audiencia de Charcas y del Arzobispado y congregaba a la población de diversos lugares que llegaban a realizar sus peticiones o a estudiar en los colegios y en la Universidad San Francisco Xavier. Al llegar las noticias de la invasión francesa a la Península en 1808, esta ciudad juró fidelidad y organizó la primera junta del territorio. En este contexto de crisis, se han desarrollado investigaciones que resaltan la construcción de la nación, por ello, este trabajo pretende ahondar en los realistas, en los olvidados o en los que fueron excluidos de las historias tradicionales. Durante los años 1809 a 1812, la población local mostró en su gran mayoría, su fidelidad a la Corona, debido a mantener la paz y la estabilidad. Este análisis identifica tiempos específicos que evidencian una apuesta por el realismo, opción política expuesta a partir de diversos acontecimientos y acciones llevados a cabo a la hora de defender las banderas del rey y también, a sus privilegios y bienes puestos en peligros con el avance de las tropas patriotas provenientes de Buenos Aires desde 1810.

Authors: Bingol Olgun , Ozdemir Guzelali , Karlidag Taner , Korucu Alperen , Yasar Niyazi Erdem , Deveci Alper
Published: March 2023

Background: Clinical studies have shown that posterior malleolar fractures treated with a posterior buttress plate have improved outcomes compared to anterior-to-posterior screw fixation. The aim of this study was to evaluate the impact of posterior malleolus fixation on clinical and functional results.

Methods: The patients with posterior malleolar fractures who were treated between January of 2014 and April of 2018 at our hospital were investigated retrospectively. Fifty-five patients included in the study were divided into three groups according to the fixation preferences of fractures (group I, posterior buttress plate; group II, anterior-to-posterior screw; and group III, nonfixated). The groups consisted of 20, nine, and 26 patients, respectively. These patients were analyzed according to demographic data, fixation preferences of fractures, mechanism of injury, hospitalization length of stay, surgical time, syndesmosis screw use, follow-up time, complications, Haraguchi fracture classification, van Dijk classification, American Orthopaedic Foot and Ankle Society score, and plantar pressure analysis.

Results: There were no statistically significant differences between the groups in terms of gender, operation side, injury mechanism, length of stay, anesthesia types, and syndesmotic screw usage. However, when the age, follow-up time, operation time, complications, Haraguchi classification, van Dijk classification, and American Orthopaedic Foot and Ankle Society scores were evaluated, statistically significant differences were observed between the groups. Plantar pressure analysis data showed that group I yielded balanced pressure distribution between both feet compared to the other study groups.

Conclusions: The posterior buttress plating of posterior malleolar fractures yielded better clinical and functional outcomes compared to the anterior-to-posterior screw fixation and nonfixated groups.

A variety of treatment modalities exist, including topical therapies and surgical excision, although both have their pros and cons. In this communication, we describe the case of a 7-year-old boy with repeated toe trauma, who developed a large nail bed pyogenic granuloma after undergoing surgical debridement and nail bed repair. He was treated with 3 months of topical 0.5% timolol maleate, resulting in complete resolution of the pyogenic granuloma and minimal nail deformity.
Robust MPC for polytopic uncertain systems via a high-rate network with the round-robin scheduling
Authors: Wang Jianhua , Wang Yiling , Wu Xialai , Ci Wenyan
Published: March 2023

This article is concerned with the robust model predictive control (RMPC) problem for polytopic uncertain systems under the round-robin (RR) scheduling in the high-rate communication channel. From a set of sensors to the controller, several sensors transmit the data to the remote controller via a shared high-rate communication network, data collision might happen if these sensors start transmissions at the same time. For the sake of preventing data collision in the high-rate communication channel, a communication scheduling known as RR is used to arrange the data transmission order, where only one node with token is allowed to send data at each transmission instant. In accordance with the token-dependent Lyapunov-like approach, the aim of the problem addressed is to design a set of controllers in the framework of RMPC such that the asymptotical stability of the closed-loop system is guaranteed. By taking the effect of the underlying RR scheduling in the high-rate communication channel into consideration, sufficient conditions are obtained by solving a terminal constraint set of an auxiliary optimization problem. In addition, an algorithm including both off-line and online parts is provided to find a sub-optimal solution. Finally, two simulation examples are used to demonstrate the usefulness and effectiveness of the proposed RMPC strategy.
Drought stress resistance indicators of chickpea varieties grown under deficit irrigation conditions
Authors: Ucak Ali Beyhan , Arslan Hüseyin
Published: March 2023

The aim of this study was to determine the drought stress resistance of three chickpea cultivars (Inci, Hasanbey and Seçkin) grown under water deficit conditions and to discuss the use of yield, crop water stress index and chlorophyll index values as drought stress tolerance indicators in breeding studies. Three drought stress levels, (full irrigation = no stress - I100, deficit irrigation = moderate stress - I50, and no irrigation = severe stress - I0) were used as irrigation treatments. The highest seed yield (1,984 kg ha−1) in severe stress conditions was recorded for the Inci cultivar with a low crop water stress index (CWSI) (0.50) and high chlorophyll index (33.60 SPAD). The lowest seed yield (1,783.66 kg ha−1) in I0treatment was noted for the Seçkin cultivar which had a high CWSI (0.58) and low chlorophyll index (32.88 SPAD). The highest seed yield (2,566.33 kg ha−1) in full irrigation was recorded for the Inci cultivar which had a low CWSI (0.19) and high chlorophyll index (44.39 SPAD), while the lowest seed yield (2,328.00 kg ha−1) in I100 treatment was recorded for the Seçkin cultivar which had a high CWSI (0.26) and low chlorophyll index (42.12 SPAD). The seed yield of the Hasanbey cultivar in both severe stress (1,893 kg ha−1) and full irrigation (2,424.00 kg ha−1) conditions was between Inci and Seçkin varieties. The chlorophyll index and yield had a significant positive (r = 0.877) correlation, while a significant negative (r = −0.90) relationship was determined between CWSI and yield. Seed yield of the Inci cultivar in I0and I100treatments and water use efficiency revealed that the Inci cultivar is resistant to drought stress. Therefore, the Inci cultivar can be used in drought stress tolerance studies. In addition, the CWSI and chlorophyll index values can be employed as resistance indicators in chickpea breeding studies to determine the drought resistant chickpea cultivars.
Modelling quarantine effects on SARS-CoV-2 epidemiological dynamics in Chilean communes and their relationship with the Social Priority Index
Authors: Salinas Dino G. , Bustamante M. Leonor , Gallardo Mauricio O.
Published: March 2023

Background

An epidemiological model (susceptible, un-quarantined infected, quarantined infected, confirmed infected (SUQC)) was previously developed and applied to incorporate quarantine measures and calculate COVID-19 contagion dynamics and pandemic control in some Chinese regions. Here, we generalized this model to incorporate the disease recovery rate and applied our model to records of the total number of confirmed cases of people infected with the SARS-CoV-2 virus in some Chilean communes.

Methods

In each commune, two consecutive stages were considered: a stage without quarantine and an immediately subsequent quarantine stage imposed by the Ministry of Health. To adjust the model, typical epidemiological parameters were determined, such as the confirmation rate and the quarantine rate. The latter allowed us to calculate the reproduction number.

Results

The mathematical model adequately reproduced the data, indicating a higher quarantine rate when quarantine was imposed by the health authority, with a corresponding decrease in the reproduction number of the virus down to values that prevent or decrease its exponential spread. In general, during this second stage, the communes with the lowest social priority indices had the highest quarantine rates, and therefore, the lowest effective viral reproduction numbers. This study provides useful evidence to address the health inequity of pandemics. The mathematical model applied here can be used in other regions or easily modified for other cases of infectious disease control by quarantine.

In the present day situation, decreasing COVID-19 risk elements also can moreover need to probably check the abilities to provide and test AI-primarily based total models for COVID-19 severity prediction. This work aimed to select the maximum affecting abilities of COVID-19 chance elements and enhance the functionality of the AI method for COVID-19 chance elements primarily based totally on the chosen abilities. In this study, proposed a method for determining whether or not a patient has a chance of contracting COVID-19 by making use of an AI characteristic that becomes incorporated into the feature-fitting learning process (FfitL-CoV19), while also taking a number of symptoms into consideration. Textual data has been divided into traditional and ensemble system learning algorithms as part of the AI characteristic that is becoming a part of the learning process that is being offered. Feature engineering has become completed the use of the AI technique and functions skills have been provided to conventional and ensemble system learning classifiers. The hybrid approach that was made is a big step up from what had been done before, and it can be very effective in all situations. Using the method shown, a structural model could be made that shows how COV-19 infections can spread and cause more infections.

O Centro de Estudos Afro-Asiáticos, do Conjunto Universitário Cândido Mendes, era a mais visível “porta de entrada” para africanos e interessados-as em África e Relações Raciais no Brasil entre as décadas de 1970 e 1990. O CEAA publicou uma revista acadêmica de referência internacional, formou muitas-os pesquisadores, realizou muitos cursos, eventos nacionais e internacionais, e acolheu a militância do movimento negro. Essa história se mostra ainda mais importante quando a questão racial está na agenda política nacional, e a trajetória tão peculiar do CEAA é referência para a crescente militância antirracista entre pesquisadores à volta da rede de NEABIs-Núcleos de Estudos Afro-Brasileiros e Indígenas, em universidades de todas as regiões do país.

Importance

It remains unclear whether comorbidities in patients with retinal artery occlusion (RAO), a rare retinal vascular disorder, differ by subtype and whether mortality is higher.

Objective

To examine the nationwide incidence of clinically diagnosed, nonarteritic RAO, causes of death, and mortality rate in patients with RAO compared with that in the general population in Korea.

Design, Setting, and Participants

This retrospective, population-based cohort study examined National Health Insurance Service claims data from 2002 to 2018. The population of South Korea was 49 705 663, according to the 2015 census. Data were analyzed from February 9, 2021, to July 30, 2022.

Main Outcomes and Measures

The nationwide incidence of any RAO, including central RAO (CRAO; International Statistical Classification of Diseases and Related Health Problems, Tenth Revision [ICD-10] code, H34.1) and noncentral RAO (other RAO; ICD-10 code, H34.2) was estimated using National Health Insurance Service claims data from 2002 to 2018, with 2002 to 2004 as the washout period. Furthermore, the causes of death were evaluated and the standardized mortality ratio was estimated. The primary outcomes were the incidence of RAO per 100 000 person-years and the standardized mortality ratio (SMR).

Results

A total of 51 326 patients with RAO were identified (28 857 [56.2%] men; mean [SD] age at index date: 63.6 [14.1] years). The nationwide incidence of any RAO was 7.38 (95% CI, 7.32-7.44) per 100 000 person-years. The incidence rate of noncentral RAO was 5.12 (95% CI, 5.07-5.18), more than twice that of CRAO (2.25 [95% CI, 2.22-2.29]). Mortality was higher in patients with any RAO than in the general population (SMR, 7.33 [95% CI, 7.15-7.50]). The SMR for CRAO (9.95 [95% CI, 9.61-10.29]) and for noncentral RAO (5.97 [95% CI, 5.78-6.16]) showed a tendency toward a gradual decrease with increasing age. The top 3 causes of death in patients with RAO were diseases of the circulatory system (28.8%), neoplasms (25.1%), and diseases of the respiratory system (10.2%).

Conclusions and Relevance

This cohort study found that the incidence rate of noncentral RAO was higher than that of CRAO, whereas SMR was higher for CRAO than noncentral RAO. Patients with RAO show higher mortality than the general population, with circulatory system disease as the leading cause of death. These findings suggest that it is necessary to investigate the risk of cardiovascular or cerebrovascular disease in patients newly diagnosed with RAO.

Published: March 2023

Photonic crystals owe their multitude of optical properties to the way their structure creates interference effects. It is therefore possible to influence the photonic response by acting on their physical structure. In this article, tunable photonic crystals made by elastic polymers that respond to their environment are explored, in particular with a physical deformation under temperature variation. This creates a feedback process in which the photonic response depends on its physical structure, which itself is influenced by the environmental changes. By using a multi‐photon polymerization process specifically optimized for soft responsive polymers such as Liquid Crystalline Networks, highly resolved, reproducible, and mechanically self‐standing photonic crystals are fabricated. The physical structure of the 3D woodpile can be tuned by an external temperature variation creating a reversible spectral tuning of 50 nm in the telecom wavelength range. By comparing these results with finite element calculations and temperature induced shape‐change, it is confirmed that the observed tuning is due to an elastic deformation of the structure. The achieved nanometric patterning of tunable anisotropic photonic materials will further foster the development of reconfigurable photonic crystals with point defects acting as tunable resonant cavities and, more in general, of 4D nanostructures.

While quasi‐2D perovskite is often used in inverted perovskite solar cells (PSCs) to improve the interfacial carrier transfer, the development of pure 2D perovskite with superior stability is rarely seen and the corresponding carrier‐extraction kinetics remains unclear. Here, a variety of hexatomic ring cations including piperidine, pyridine, and cyclohexane are introduced to modify the perovskite/electron transport layer interface. The Dion–Jacobson phase 2D cladding (n = 1) based on 3‐(aminomethyl) piperidinium is proved to form a coordinated energy landscape and homogeneous surface potential distribution, and effectively prolong the electron diffusion length (≈1.58 µm) and accelerate the hot‐carrier extraction rate (2.5 times that of Control at 400 K). Furthermore, the quasi‐2D treatment (n ≈ 3,4) demonstrated a slight escalation in short‐circuit current, but failed to inhibit the interdiffusion of Ag, Pb, and I under illumination. Finally, one of the state‐of‐art power conversion efficiency (PCE) for MA‐free inverted PSCs is achieved at 23.62% with increased open‐circuit voltage (≈1.15 V) and fill factor (≈82.8%). Most importantly, 89% and 93.6% of initial PCE are retained after 720 h under 85 °C heating and 1000 h under maximum power point tracking, illustrating satisfactory thermal and operational stability with pure 2D perovskite capping layer.

Chloride oxidation is a key industrial electrochemical process in chlorine‐based chemical production and water treatment. Over the past few decades, dimensionally stable anodes (DSAs) consisting of RuO2‐ and IrO2‐based mixed‐metal oxides have been successfully commercialized in the electrochemical chloride oxidation industry. For a sustainable supply of anode materials, considerable efforts both from the scientific and industrial aspects for developing earth‐abundant–metal‐based electrocatalysts have been made. This review first describes the history of commercial DSA fabrication and strategies to improve their efficiency and stability. Important features related to the electrocatalytic performance for chloride oxidation and reaction mechanism are then summarized. From the perspective of sustainability, recent progress in the design and fabrication of noble‐metal‐free anode materials, as well as methods for evaluating the industrialization of novel electrocatalysts, are highlighted. Finally, future directions for developing highly efficient and stable electrocatalysts for industrial chloride oxidation are proposed.

This article reports on the charge transport characteristics across the potential barrier generated by a local dual‐gate modulation at the surface of p‐doped graphene via surface contact on a fluorocarbon (CF) thin film. Owing to simple physical contact, the strong electron affinity of the fluorine atoms in CF stably increases the hole density of graphene, which leads to a massive p‐doping effect in graphene. Then, potential barrier height can be generated and modulated across the channel by forming a local dual‐gate device structure. Different gate biases in dual‐gate operation can split electrical characteristics of a single graphene into highly conductive region and region of sparse charge density, creating large chemical potential difference at the boundary between the two which determines the value of barrier height. Moreover, the device characteristics follow a simple model of the metal–semiconductor junction well in addition to the effect of charge concentration discrepancy in graphene. These results reveal that it is possible to create an ideal and controllable potential barrier composed of a single material using the highly doped graphene with the local dual‐gate structure.

Published: March 2023

Poly(dimethylsiloxane) (PDMS) has been widely employed in biomedical disciplines due to its several advantages, including biocompatibility, nontoxicity, and low‐cost preparation. However, the intrinsic hydrophobicity of this material encourages biofouling and reduces cell regulation capacity, thereby limiting its biomedical applicability. The purpose of this study is to explore the surface modification and functionalization of PDMS and PDMS‐based biomaterials to improve their properties for biomedical applications. The content of this review is organized based on physical and chemical surface modification strategies to improve surface hydrophilicity to enhance antibiofouling and the regulation of immunomodulation and cell modulation on the surface of PDMS and PDMS‐based biomaterials. Future developments in this area are also discussed.
