Pilotos para la transferencia de conocimiento entorno a la digitalización en la construcción en Medellín, Colombia
Authors: Rúa Machado Carlos Andrés , Arboleda López Sergio Andrés , Serna Machado Nicolás
Published: December 2022

La investigación de la cual deriva el presente artículo busca fomentar el aprendizaje mediante la articulación de escenarios CAE (Clúster-Academia-Empresa) que permitan socializar criterios y establecer lenguajes formales del conocimiento frente a la adopción de BIM (Building Information Modelling) de forma interactiva y predefinida. Para ello se formaron grupos focales con el objeto de nivelar conceptualmente los alcances de BIM desarrollando criterios en común, generándose un banco de preguntas y respuestas relacionadas al tema; posteriormente, se seleccionan las brechas para consolidar este proceso de medición con las entrevistas de Santiago de Chile, para identificar las principales entidades y empresas promotoras de su digitalización y comprender sus particularidades, así como las posibilidades de transferencia de conocimiento como escenario de digitalización en la construcción.  Así pues, se identifica que BIM se entiende como una metodología, pero su gestión, conocimiento y práctica son bajos; la visualización, coordinación y gestión de presupuestos, es incipiente. Por consiguiente, se concluye que la socialización de estos pilotos guiados permite una mejor comprensión entre actores y ayuda a entender las interfases de información.
A Method of Accelerated Quantitative Evaluation of Components of FPGA-based Security Systems
Authors:   G.E. Pukhov Institute for Modelling in Energy Engineering National Academy of Sciences of Ukraine, Hilgurt S.Ya.
Published: December 2022

Recently, various approaches have been successfully used in information security tools to detect harmful activity, including artificial intelligence technologies. But only the signature approach can completely eliminate recognition errors. That is especially important for critical infrastructure objects. One of the main disadvantages of signature tools is the high computational complexity. Therefore, the developers of such systems turn to hardware implementation, primarily on a reconfigurable platform, that is, using FPGAs. The ability to quickly reprogram FPGAs gives reconfigurable security systems unprecedented flexibility and adaptive possibilities. There are many different approaches to the construction of hardware pattern matching circuits (that are parts of signatures). Choosing the optimal technical solution for recognizing a specific set of patterns is a non-trivial task. For a more efficient distribution of patterns between components, it is necessary to solve an optimization task, the objective function of which includes the quantitative technical characteristics of hardware recognition schemes. Finding these values at each step of the algorithm by performing the full digital circuit synthesis procedure by the CAD is an unacceptably slow approach. The method proposed in this study for the accelerated quantitative evaluation of components of reconfigurable signature-based security systems, based on the use of the so-called evaluation functions, allows solving the problem.
Religious paradigms of medieval medicine
Authors:   Kharkiv Medical Academy of Postgraduate Education, Oparin O.А.
Published: December 2022

It is shown that in the Middle Ages the sanitary and epidemiological state was characterized by the absence of a sewerage and water supply system; complete unsanitary conditions, both in the city as a whole and in individual houses; lack of elementary rules of personal hygiene; a high percentage of infant mortality and almost unceasing epidemics. It is shown that medicine in the Middle Ages was based on the principles of scholasticism, which rejected in principle any scientific discoveries and opposed faith and science, which made its development impossible in principle. The methods of treatment used by medieval medicine were based on gross superstitions, which boiled down to belief in the healing power of amulets and talismans; attributing the influence on human health to the location of the stars; the role of conspiracies and the healing power of crushed stones and minerals. It has been established that the basis of medieval medicine was primarily the teachings and ideas of the medieval church about the immortality of the soul, saints, illness, education, in which rude pagan beliefs and philosophy prevailed, making not only impossible the development of medicine as such, but also leading to mass epidemics, unsanitary conditions, the growth of neuropsychiatric diseases, and decrease of the duration and quality of life of the population.
Transient Permanence
Authors: Lending Mari
Published: December 2022

There are few places where the tenacious dichotomy of copy and original deconstructs itself more forcefully than in the trajectory we refer to as classical sculpture. This process is intrinsic to the assumed origins of the classical and the idea of the antique original, and despite the existence of celebrity pieces such as the Venus de Milo, the Laocoön, or the Farnese Hercules, objects that crowds have lined up for centuries to see in Paris, Rome, and Naples, respectively. Few statues can be authorized as first, original versions: the history of classical sculpture is as much a history of the serialized original as of the serial copy, as Salvatore Settis and his team exquisitely displayed in the concurrent exhibitions Portable Classic and Serial Classic at the Prada Foundation in Venice and Milan in 2015. While the Milan edition revolved around seriality, materiality and surface, the Venice exhibition displayed antique repetitions through scale, miniaturization and portability. Hackneyed conceptions of origins and originality collapsed in the line–up of a Farnese Hercules series in Palazzo Corner della Regina on the Grand Canal, and in the numerous antique variants and derivatives of iconic statues such as the Discobolus and the Crouching Venus in Milan. Entering these two spaces was a profound bodily experience of the repeatability, versatility, and adjustability of the classical tradition.

Authors: Cunha Elcemir Paço , Guedes Leandro Theodoro
Published: December 2022

RESUMO O objetivo do presente artigo é apresentar a propositura de administração política de Roberto Simonsen como variante da ideologia da terceira via. Para tanto, utilizou-se os fundamentos materialistas da determinação social do pensamento que reconhece não apenas as condições concretas, como pressupostos objetivos para as formações ideais, como também sublinha a particularidade dos casos específicos. Assim, o ideário de Simonsen, extraído dos seus textos entre 1919 e 1947, foi considerado a partir dos traços semicoloniais do Brasil de então. As conclusões apontam para aspectos progressivos e regressivos na propositura de Simonsen, salientando que a ideologia da terceira via foi adaptada às condições nacionais à luz das aspirações industrialistas.

Authors: Melo Mariana Ramos de , Anjo José Edemir da Silva , Bolzan Rosiane da Silva Viana , Martins-Silva Priscilla de Oliveira
Published: December 2022

RESUMO O presente estudo teve o objetivo de explicar como barreiras percebidas na carreira impactaram o autogerenciamento de carreira de estudantes de uma universidade pública no contexto da pandemia da Covid-19. Ao seguir por uma abordagem qualitativa, foi adotada a pesquisa documental como estratégia metodológica ao partir da coleta de postagens da página “Segredos”, na rede social Facebook, que é um espaço de discussões da comunidade acadêmica. Os dados foram codificados, analisados e orientados pela análise de conteúdo com categorização temática à posteriori. Por meio de tal análise, obteve-se a formação das categorias temáticas: barreiras percebidas na carreira e autogerenciamento de carreira. Os resultados apontaram que diante do contexto atípico de crises contextuais, os estudantes percebem inúmeras barreiras externas (educação, economia, política, restrições financeiras e condição familiar) e internas (saúde mental). Com a pandemia, o autogerenciamento de carreira se tornou mais intenso e complexo, por meio do qual os estudantes vêm adotando ações de enfrentamento produtivas e não produtivas frente às barreiras percebidas. Como contribuição teórica deste estudo, destaca-se a complexificação do autogerenciamento de carreira, pois no período pandêmico é possível que o enfrentamento não produtivo possa se tornar, relativamente, um enfrentamento produtivo, auxiliando no enfrentamento de barreiras pelos universitários.
Elaborações do traumático através da arte: refúgio, cultura e memória
Authors: Alves Lucas de Oliveira , Martins-Borges Lucienne , Marsillac Ana Lúcia Mandelli de
Published: December 2022

Resumo. Este artigo tem como objetivo trazer uma discussão sobre os eventuais traumas provocados pelas situações de refúgio, bem como sobre o potencial da arte em auxiliar na elaboração destes traumas. Partindo de uma interlocução entre psicanálise e teorias sociais críticas, desenvolvemos algumas considerações acerca da psicologia do trauma e sobre o processo de elaboração psíquica por meio da arte. Compreendemos que o contato com a criação artística, seja na posição de criador, espectador ou através da arteterapia, tem como efeito a inclusão cultural de sujeitos refugiados no país de acolhimento, bem como a criação de memórias coletivas. Consideramos que a inclusão cultural e a reconstrução de memórias contribuem para a elaboração psíquica das violências, perdas e lutos que costumam caracterizar o refúgio, além de pluralizar experiências e dinamizar o laço social.
The Heterodiscursivity in Fantastic Narratives of Social Tradition
Authors: Araújo Nádia Barros , Araújo André Luís de
Published: December 2022

ABSTRACT This article investigates the presence of heterodiscourse in narratives of oral tradition. Therefore, the theoretical foundation is based on the Bakhtinian perspective, which understands the discourse, in the literary narratives, as marked by heterodiscursivity, evidencing a diversity of social voices that signal ways of understanding and points of view about the world. The analysis of the corpus, composed of two narratives from the oral tradition, points out, therefore, that the voices of the narrator, of the traditional storytellers and of the characters appear in constant dialogicity with the social voices, guided by axiologies, positions and evaluative centers of social, cultural and historical order. The study thus found ways of reflecting and refracting the events of existence, moral frameworks that guide them and the understanding of ways of being and acting in concrete situations of life in society, in line with the dialogic assumptions of the research.

Authors: Zapata Edwin Alexander Hernandez , Herrera Milton Danilo Morales , Tapias Nayib Esther Carrasco
Published: December 2022

RESUMEN El artículo es producto de la investigación “Significados del trabajo y prácticas de reintegración laboral en excombatientes”. Su objetivo fue analizar las ideologías en cuanto formaciones discursivas en las que se articularon los motivos de afiliación de excombatientes a grupos armados guerrilleros. Se utilizó un diseño cualitativo, el análisis del discurso como método y la entrevista a profundidad como técnica de generación de información. Los resultados muestran que, las versiones sobre los motivos de afiliación al grupo armado van más allá de la simpatía ideológica mas no de lo ideológico. Se exponen seis motivos de afiliación que se analizan a partir de los efectos de ciertos discursos en la subjetividad de los excombatientes. Se concluye que, el camino hacia la construcción de paz implica nuevas narrativas sobre la comunidad, desvinculadas del individualismo como ethos contemporáneo, asimismo, del paradigma inmunológico y de normalización a partir del cual se ha pensado al excombatiente.

Published: December 2022

RESUMO O artigo inscreve-se nas disputas pela hegemonização de um sentido particular de escola pública democrática em tempos de coronavírus, nos quais o ensino remoto se tornou alternativa obrigatória para as políticas educacionais. Em diálogo com as contribuições teóricas pós-estruturalistas, o texto tem por objetivo analisar as disputas entre os processos de significação de termos como acesso universal, democracia, conhecimento escolar, relação com o saber e com a aprendizagem, mobilizados no Plano de Ação Pedagógico elaborado em 2020 pela Secretaria de Estado de Educação do Rio de Janeiro. A análise desse documento curricular oferece evidências empíricas para a compreensão dos efeitos da intensificação, no contexto pandêmico atual, da articulação discursiva de interesses neoliberais que colocam a instituição escolar sob ameaça. Ao longo de nossa argumentação, buscamos explorar, para além da linguagem da denúncia, possibilidades de reinvenção para uma possível escola de depois.
Analysis of senior travel constraints and negotiation process in the COVID-19 pandemic situation
Authors:   The Tourism Sciences Society Of Korea, Lee Hye Rin
Published: December 2022

The 2020 coronavirus pandemic has had a significant impact on the tourism industry as well as the lives of senior travelers. The pandemic imposed a new constraint on seniors who actively planned to travel after retirement, altering their leisure lifestyle. The goal of this research is to delve deeply into the travel constraints and negotiation process of senior travelers during the corona pandemic. In order to achieve the study's goal, in-depth interviews with 9 seniors were conducted and analyzed using the grounded theory method. The analysis produced a total of 51 concepts, 18 subcategories, and 9 categories. During the corona pandemic, the central phenomenon was the recognition of travel constraints, and action/interaction strategies included continuing to travel, engaging in existing leisure activities, and trying new leisure activities. Participants in the study who were restricted from traveling due to the pandemic experienced a positive shift in perception, allowing them to rediscover and appreciate their daily lives, and the path to pursue a leisure lifestyle was divided into travel regression, leisure regression, and leisure diversity. Based on this, a paradigm model was presented, and the core category'moving to a more advanced leisure life through negotiation of travel constraints during the COVID-19 period' was derived. This study is theoretically significant because it thoroughly examined the senior traveler's constraint negotiation process and presented a model for the new phenomenon of a pandemic. Furthermore, the research findings on negotiation strategy, negotiation influencing factors, and type classification have important implications for senior leisure and tourism policies and practices.

Introduction: This study aimed to determine the awareness and uptake of surgery as a treatment option in patients with glaucoma on medical treatment.Methods: A cross-sectional survey was conducted among consenting patients with primary glaucoma who were on medical treatment. The survey was conducted in two eye care facilities (government-owned and private). After responding to a questionnaire, patients had ocular examinations, including visual acuity, anterior/posterior segment examinations, gonioscopy and central visual field testing. Information was obtained on the patients’ awareness of a surgical option, and reasons for non-uptake among those offered surgery were recorded. Logistic regression analysis was used to identify possible predictors of awareness of glaucoma.Results: Across both facilities, 299 patients with glaucoma with a mean age of 63.9 years participated in this study. There were 167 (55.9%) male and 132 (44.1%) female participants. Two hundred and sixty-seven (89.3%) had a formal education, and of the 169 evaluated for visual fields in the worse eye, 129 (76.3%) had severe (advanced) glaucoma. Only 79 (26.4%) of the participants were aware of surgery as a treatment option for glaucoma. The multivariate analysis found that female patients, patients from the private eye care facility and patients with primary angle closure glaucoma patients were more likely to be aware of glaucoma surgery than male patients, patients from the government-owned eye care facility and patients with primary open-angle glaucoma. Patients with primary angle closure glaucoma were more likely to be aware of glaucoma surgery than those with primary open-angle glaucoma. Cost was identified as the major barrier to the uptake of glaucoma surgery when it was recommended, followed by fear of blindness. Age, level of education and severity of disease had no statistical relationship to awareness of glaucoma surgery.Conclusion: Incorporating routine glaucoma education and counselling into glaucoma care protocols will likely improve awareness of glaucoma surgery as a treatment option.

Following the third molar, the maxillary canine holds the second position of the most frequently impacted tooth. The orthodontic management of the tooth depends on its position and in many cases, the orthodontic guidance is graded difficult with poor prognosis. Autotransplantation of canine is a viable option in such cases if the tooth can be atraumatically removed. The case reports a young female with an impacted maxillary canine, which was graded difficult. The case was managed using auto transplantation and orthodontic alignment.
Protective Effects of Black Tea (Camellia sinensis) Extract on Endosulfan Induced Oxidative Stress, Inflammation and Hepatic Damage in Rats
Authors: Banerjee Maitrayee , Banerjee Oly , Singh Siddhartha , Mukherjee, Sandip
Published: December 2022

With the agricultural expansion the use of pesticides is increasing rapidly in developing countries. Endosulfan, an organochlorine insecticide, is a broadspectrum effective compound used in wide variety of agricultural crops but known to generate free radicals in the liver and caused hepatotoxicity. Thus, we considered it necessary to explore the protective effect of black tea extract against endusulfan mediated hepatotoxicity. 18 male albino Wistar rats were divided into 3 groups: Control, endosulfan treated (5mg/kg body weight/day) and endosulfan+black tea extract treated (1ml of 2.5gm%/100gm of body weight/day). After 30 days of treatment period, all the animals were sacrificed, and blood and liver tissue were collected. Serum and tissue cholesterol, serum liver function parameters, liver oxidative stress parameters and serum proinflammatory cytokines were measured. Liver sections were stained with haematoxylene and eosine and histological evaluation was done. Results revealed that endusulfan induces oxidative stress in liver by altering oxidant/antioxidant balance, and causes inflammation resulting into hepatic damage. Black tea extract supplementation shows considerable protection against endosulfan mediated changes in liver. Thus, black tea extract exerts ameliorative effect against endosulfan mediated liver toxicity.
Nepali Women at Risk from Misguided Anti-Trafficking Strategies
Authors:   Institute of Development Studies, Oosterhoff Pauline , Snyder Karen , Sharma Neelam
Published: December 2022

There are burgeoning hospitality, entertainment, and wellness industries in Nepal. The label ‘Adult Entertainment Sector’, used in anti-trafficking efforts, has resulted in stigmatisation of the owners and, mainly female, workers of some businesses in these industries. Labour intermediaries, who help businesses get employees and workers find jobs, are a critical and often misrepresented part of these informal industries. Women are stuck with few options for safe employment in Nepal or foreign labour migration. Supporting the easy registration and monitoring of these businesses and social protection will improve Nepal’s economy and enhance working conditions.

Published: December 2022

L’art a été utilisé pour communiquer les préoccupations environnementales dans les pays sahéliens. Néanmoins, le dialogue dirigé par les arts entre les acteurs politiques et les citoyens est cependant rare, bien qu’il ait le potentiel de trouver des solutions aux problèmes socio-environnementaux complexes. Il est indispensable d’exploiter ce potentiel, alors que des défis, tels que le changement climatique, s’accélèrent et touchent les populations. La sensibilisation aux processus de dialogue menés par les arts pourrait être renforcée, parallèlement à davantage de recherches sur les contextes dans lesquelles ils sont appropriés et sur la meilleure façon de les utiliser.

Selective laser trabeculoplasty in combination with YAG-laser trabeculostomy was performed in the projection of theoutflowmeshwork. Hypotensive effect was 31,1 % of the initial intraocular pressure level on the 1st post-op day and remained for a month after the surgery due to the outflow improvement of the intraocular fluid by 62,5 %. The YAG-laser and OCT data allow optimization of YAG trabeculostomy, providing an alternative noninvasive laser treatment for patients with primary open angle glaucoma.
Numerical Orbital Stability Analysis of Nonresonant Periodic Motions in the Planar Restricted Four-Body Problem
Authors:   Moscow Aviation Institute, Sukhov E. A. ,   Moscow Aviation Institute, Volkov E. V.
Published: December 2022

We address the planar restricted four-body problem with a small body of negligible mass moving in the Newtonian gravitational field of three primary bodies with nonnegligible masses. We assume that two of the primaries have equal masses and that all primary bodies move in circular orbits forming a Lagrangian equilateral triangular configuration. This configuration admits relative equilibria for the small body analogous to the libration points in the three-body problem. We consider the equilibrium points located on the perpendicular bisector of the Lagrangian triangle in which case the bodies constitute the so-called central configurations. Using the method of normal forms, we analytically obtain families of periodic motions emanating from the stable relative equilibria in a nonresonant case and continue them numerically to the borders of their existence domains. Using a numerical method, we investigate the orbital stability of the aforementioned periodic motions and represent the conclusions as stability diagrams in the problem’s parameter space.

The Cirasea sub-watershed is one of the sub-watersheds that has an important role in the management of the Upper Citarum watershed. The decline in land use has an impact on the hydrological system of the watershed, which is caused by changes in land use. The land-use change is determined by analyzing the results of the classification using the Maximum Likelihood Classification (MLC) algorithm in QGIS software. Land use classification using Landsat Image 2009-2019. The classification results include forest, secondary forest, built-up areas, open land, plantations, dryland farming, rice fields, shrubs, and water bodies. The accuracy test using the Kappa Index reached 85.15% or almost perfect. The land use classification that occurs shows changes in the area between 2009 and 2019. The land that has decreased is 1,437.13 ha of forest, 1,336.21 ha of rice fields, 367.83 ha of secondary forest, and 94,148 ha of dryland farming. Meanwhile, land that has increased is 1,476.69 ha of open land, 1,056.39 ha of built-up areas, 463.63 ha of shrubs, 235 ha of plantations, and 3.07 ha of water bodies.

We describe and discuss a field observation of a strongly speckle-breasted and barred Black Falcon Falco subniger that also, unusually, had yellow feet and cere and pale-yellow orbital rings. We also found several museum specimens with ‘variegated’ plumage and yellow bare parts. We speculate that yellow bare parts in this species might occur only in some individuals, perhaps mostly males, of the most variegated (pale-marked) plumage types, and that these correlated features may be age-related characters that deserve further investigation. We also discuss the implications for field identification.
An Evolutionary Sequential Transfer Optimization Algorithm for Well Placement Optimization Based on Task Characteristics
Authors: Qi Ji , Zhang Kai , Xue Xiaoming , Zhang Liming , Zhong Chao , Wang Haochen , Yao Jun
Published: December 2022

Evolutionary transfer optimization (ETO) algorithms with the ability to learn from past tasks have made breakthroughs in more and more fields. When the experience embedded in the past optimization tasks is properly utilized, the search performance will be greatly improved compared to starting from scratch. Autoencoding evolutionary search (AEES) is an efficient ETO paradigm proposed in recent years. The solutions of each task are configured as input and output of a single-layer denoising autoencoder (DAE), and the across-problem mapping is established by minimizing the reconstruction error, which makes it possible to explicitly transfer the solutions across heterogeneous problems. However, despite the success of AEES, the population of the optimization task contains little information about the characteristics of the task and it is highly stochastic, especially in the early stages of searching. This restricts the effectiveness of the mapping constructed via AEES. On the other hand, most tasks do not save all candidate solutions in the search, which greatly limits the possibilities of traditional AEES applications; for example, well placement optimization (WPO) problems, which are a common engineering optimization problem in the oil industry. To overcome such limitations, a sequential ETO algorithm for WPO problems based on task characteristics and an autoencoder is developed in this paper. It uses the implicit relationship between reservoir characteristics and optimal well locations to learn from past tasks, and a mapping is calculated to transfer knowledge across tasks. The proposed algorithm aims to speed up the search for the optimal well locations and reduce the required time for WPO. The learned mapping is established by configuring the characteristics of past and current tasks as input and output of a single-layer DAE. The derived mapping holds a closed-form transformation matrix across heterogeneous tasks, and the optimal solution of the past task can be easily transferred to a dominant solution of the current task by matrix calculation, thus it will not bring much computational burden in the evolutionary search while improving search performance. Furthermore, according to the specific task, the construction scheme of the matrix of characteristics can be flexibly extended to achieve effective search enhancement. The comprehensive empirical studies of WPO and statistical analysis are carried out to verify the effectiveness.

Published: December 2022

This research work implies the development of a reliable, inexpensive, better and eco-friendly way to fabricate Cd(OH)2 and CdO nanoparticles green synthesis approach using three different source materials. The veldt grape leaf act as a chelating agent. The physical properties of prepared samples were analyzed by various characterization techniques such as X-Ray Diffractometer, Fourier Transform Infra-Red, Scanning Electron Microscopy, X-Ray Energy Dispersive Spectrometer, High-Resolution Transmission Electron Microscopy and UV-Visible Spectrometer. The investigation of the structural analysis showed the existence of Cd(OH)2, mixed Cd(OH)2/CdO and CdO nanoparticles. The optical absorption wavelength at 294nm in UV-Vis spectra confirmed that the reduction of Cd2+ ions. FTIR spectra display the vibrational modes of veldt grape leaf extract involved in chemical bonding and reductions. From EDAX spectrum confirmed the presence of Cd and O elements in the prepared samples. SEM and HRTEM images revealed nanorods, platelet and spherical shape morphologies with particle size ranging from 5.7 to 29nm. The photocatalytic activity of prepared nanoparticles was tested by degrading anionic and cationic dyes like congo red, methyl orange and crystal violet under UV-light irradiation. As well as antimicrobial activity was evaluated against gram-positive staphylococcus aureus, gram-negative proteus vulgaris and fungal- aspergillus niger. Comparing these three products CdO NPs exhibit high performance on both microbial and photocatalytic activity without a secondary product. Thus, the prepared CdO nanoparticles may further use in sewage treatment and biomedical applications.
Fractal Stability Applied to Forestry Patches
Authors: Nascimento Antonio Teófilo Ataide do , Santos Stefanie Chaves dos , de Matos Mara Rojane Barros , Orge Maria Dolores Ribeiro
Published: December 2022

Context:
The fractal analysis has been used by landscape ecologists as a shape metric in order to quantify the complexity of landscape patches. However the use of fractal geometry in ecology possesses an unexplored potential. We then developed a broader study of shapes with unitary fractal dimension.
Objectives:
Our aim is to amplify the use of fractal dimensions as a metric of shape in the analysis and discovery of forestry landscape patches with unitary fractal dimension. Furthermore, we develop a method for monitoring and recovery of forestry patches.
Methods:
We establish a method of expansion in order to obtain patches with a good perimeter-area ratio, i. e., unitary fractal dimension. In order to do that, to each landscape patch we associate a polygon and, to each side, we define a locus that expands the polygon so that its fractal dimension is equal to one.
Results:
This study reveals a range of patches’ shapes with unitary fractal dimension. Inspired by the proposed method's recursion we denote them as fractally stable polygons. To each side of the polygon we set a condition of expansion possibility. The locus of expansion was also defined. Additionally, we define a test of global expansion.
Conclusions:
Through the developed method it is possible to ascertain when the perimeter-area ratio of a landscape patch is compromised. To expandable sides, the method provides the locus of recovery of the perimeter-area ratio. This enables a wider applicability in the analysis of forestry fragmentation through fractal dimension.

Purpose; The current study aimed to investigate the oxidative stress in diabetic rat liver as well as the protective effects of N-acetylcysteine (NAC)on irisin expression.
Methods; Twenty-eight male Wistar rats were divided into four groups, 7 rats in each group and 30-d regimens of experimental or control groups. NAC treated group: 100mg/kg once daily was administered intraperitoneally (i.p.). Diabetes-induced group: Single dose intraperitoneal injection of streptozotocin (STZ) (50mg/kg B.W.) was used to induce diabetes mellitus in overnight fasting Wistar rats. By determining blood glucose concentration in STZ-induced rats 72 hours after injection of STZ, diabetes was assessed. DM+NAC group: STZ-induced DM plus NAC as described previously. Serial and liver samples were collected on the 30-day and after overnight fasting. Biochemical analyses were performed to measure total antioxidant status (TAS), total oxidant status (TOS), and Malondialdehyde (MDA)levels. Each liver sample was weighed, then prepared for histopathologic evaluation by light microscopy.
Results; There was a statistically significant decrease in TAS levels and an increase in TOS and MDA levels in the DM group compared to the control group.
In contrast, TOS and MDA levels were found significantly decreased, and TAS levels increased in the serum and liver tissues of the DM+NAC group compared to the DM group. Liver samples were also used for histopathological examination using hematoxylin-eosin and immunohistochemical staining. STZ-induced liver injury via increasing oxidative stress, sinusoidal dilatation, degeneration of hepatocytes, and in irisin, and immunoreactivity. NAC significantly reduced the STZ-induced hepatotoxicity.
Conclusion; In the early period of diabetes, due to the antioxidant properties of irisin related to the sudden response of liver tissue to oxidative stress, it is thought that the immunoreactivity in the tissue increases in the early period. As a result, NAC in diabetic rat liver tissue was found to suppress oxidative damage and irisin immunoreactivity.

This paper shows how location-based indicators can influence consumer confidence in India. We capture local economic activity using city-wise night-time luminosity (NTL) data. Using data on unit-level observations on consumer confidence from the Consumer Confidence Survey (CCS) by the Reserve Bank of India from June 2016 to November 2021, we find that night-time luminosity positively impacts the perception and future outlook of Indian households. Our results are robust even after controlling for state-wise urban inflation. We also find the dynamic effect of NTL on consumer sentiments. Finally, we extend our study to analyze the impact of NTL on several individual components of household sentiments from the RBI survey, such as household perception and outlook on household income, spending, employment, and general price levels. Overall, our results provide fascinating insights about using NTL as a measure of local economic indicators and its implications on households' sentiment indicators.

Background:Emerging evidence indicates that gut microbial dysbiosis is associated with the development of antipsychotic-induced overweight/obesity in schizophrenia (SZ). We aim to determine the taxonomic composition and metabolites profiling of “obesogenic” microbiota in SZ patients after chronic antipsychotic medication.
Results:Our retrospective survey identified two groups of population separated by BMI, with 1/3 patients developing overweight/obesity after chronic antipsychotics treatment. Then, based on the 16S rRNA sequencing and multi-omics analyses, we found that SZ patients with overweight/obesity had lower relative abundances of the signature bacteria genera such as Bacteroides, Parabacteroides, Akkermansia, and Clostridium when compared to individuals with normal BMI. Further investigation revealed dysregulated energy expenditure and nutritional metabolism coupled with severe clinical indices and decreased levels of beneficial metabolites, e.g. indole-3-carboxylic acid, and propionic acid. The signature bacteria were positively associated with host metabolic homeostasis, according to the redundancy and co-occurrence analysis. Moreover, leveraging the data from first-episode drug-naïve SZ (FSZ) patients at 1-month and 1-year follow-up, both artificial neural network and random forest classifier-based prediction models demonstrated a strong ability of microbial profiles to predict antipsychotic-induced weight gain. Importantly, FSZ patients with a higher relative abundance of Parabacteria distasonisare less susceptible to antipsychotic-induced weight gain.
Conclusion: Gut microbiota could serve as a noninvasive approach to predict antipsychotic-induced weight gain, guiding clinical antipsychotics administration and developing novel therapeutic strategies for the weight management in SZ.

Hydroxyl radical has been widely applied in the non-food fields, but whether its feasibility for treating fruits and vegetables remains unknown. In this work, effects of hydroxyl radical water (HRW) treatment on functional components, volatile compounds, and preservation properties of cherry tomato, grape, coriander and celery were investigated. Results showed that HRW treatment could be significantly effective on delaying the color change and decay of fruits and vegetables. Besides causing a slim loss of total sugars, HRW-treated samples exhibited different losses of total phenols and ascorbic acid. The total phenol and ascorbic acid of celery were lost by 17.95% and 13.01% respectively, which may be caused by excessive surface area, indicating that the applicability of HRW to celery is still to be discussed. The loss of functional components of both fruits could be controlled under 4%. Phenolic profiles and volatile compounds kept almost steadily during treatment. Notably, the increased contents of partial ester compounds might improve the sensory of fruits and vegetables, cherry tomatoes treated with HRW showed an increase of 77.28% in ethyl caproate. Moreover, the reduction of some compounds obtained from the decomposition of fatty acid hydroperoxides may enhance the fresh odor of fruits and vegetables. Accordingly, HRW treatment is a safety and environmental technology for post-harvest processing of fruits and vegetables.
An approach for solving split common fixed point problems with multiple output sets that uses dynamic step sizes
Authors: Cui Huanhuan
Published: December 2022

We investigate split common fixed point problems with multiple output sets in this paper. We devise a new iterative approach to approximate its solution, in which the step size is determined independently of the norm of linear maps and the coefficient of nonlinear maps.
Under appropriate conditions, we establish two convergence theorems that cover some existing results as a special case.

Gutman and Trinajstic deducted that total π-energy of a chemical molecule depends upon a numeric value which is termed as zagreb index. In that same report, they also defined a term for a particular atom with respect to other atom which is away from at a distance two. This quantity provides π-energy for a molecule. Now a days, in subject context, this quantity is termed as connection number. In this paper, we have discovered a new graph. It is composed of p-sided polygon in two dimensional rhombohedral plane. This 2D network astonishingly a new discovery in literature, its topological properties are explained via different connection numbers.

Obrazovanje učenika s teškoćama za vrijeme pandemije pokazalo se uistinu izazovnim. Postojala je potreba za dodatnim prilagođavanjem individualiziranog pristupa učenicima s različitim teškoćama zbog održavanja nastave na daljinu, što je posljedično moglo dovesti do stresa učitelja. Cilj ovoga istraživanja bio je ispitati zastupljenost učenika s teškoćama i vrstu primjerenog programa odgoja i obrazovanja. Također se željela ispitati razina stresa učitelja u odnosu na različite aktivnosti prilagođavanja za učenike s teškoćama za vrijeme održavanja nastave na daljinu tijekom pandemije u odnosu na tradicionalno poučavanje prije pandemije. U istraživanju je sudjelovalo 324 učitelja iz tri županije na području sjeveroistočne Hrvatske. Istraživanje je provedeno kao transverzalno u kojem su učitelji procijenili percipirani stres za vrijeme nastave na daljinu i za vrijeme tradicionalne nastave prije pojave pandemije. Dobiveni rezultati pokazuju da nastavu pohađa oko 10% učenika s teškoćama te preko 80% razreda ima barem jednog učenika s teškoćama. Najviše je onih učenika s teškoćama koji se školuju prema redovitom programu uz individualizirane postupke (57,1%). Prema redovitom programu uz prilagodbu sadržaja i individualizirane postupke školuje ih se 48,1%, a 10,8% ih se školuje po posebnom programu uz individualizirane postupke. Učitelji procjenjuju da su doživjeli značajno više razine stresa u svim područjima prilagodbi tijekom nastave na daljinu. Stresnije im je bilo prilagođavati nastavne i dodatne materijale, prilagođavati vrijeme za ispunjavanje zadataka, pružati individualnu podršku i prilagođavati postupke vrednovanja. Učitelji su bili izloženi različitim dodatnim izvorima stresa - prilagođavanju učenicima s teškoćama i nastavi na daljinu. Budući da učitelji inače doživljavaju visoke razine stresa, potrebno ih je što bolje pripremiti na krizne situacije te na načine prilagođavanja različitim potrebama učenicima, s ciljem preveniranja stresa i razvijanja adaptivnih načina suočavanja sa stresom. Ključne riječi: učenici s teškoćama, prilagodbe, inkluzivno obrazovanje, nastava na daljinu, pandemija
