Analysis of Time Loss Injury in Korean Professional Baseball Players
Authors: Song Mun-Ku , Kang Hyun-Sik
Published: March 2024

PURPOSE: This prospective cohort study aimed to investigate the epidemiology of time-loss (TL) injuries in 68 Korean Baseball Organization (KBO) players aged 26.6±5.4 years (31 pitchers and 37 field players).METHODS: Injury data collected during the 2021-2022 KBO league seasons were used to calculate the injury rate (IR), IR ratio (IRR), and TL. IR was calculated as follows: (total number of injuries×100)÷(total number of game exposures). IRR was computed as follows: (IR of pitchers)÷(IR of fielders). TL was defined as an injury that resulted in the inability to compete or participate in standard routines.RESULTS: A total of 92 TL injuries were recorded from 5,320 athlete-exposures (1.7 per 100 athlete-exposures). Pitchers exhibited a 1.7-fold increase in IR (IRR =1.69, 95% CI=1.05-2.61, p=.018) and a 2.6-fold increase in the rate of severe injuries that resulted in a TL of ≥3 weeks (IRR=2.59, 95% CI=0.93-7.10, p=.045) compared to field players. The trunk/spine (20.6%) among pitchers and thigh/groin (22.4%) among field players were the most frequently injured body parts. Overuse (38.2%) and batted ball contact (38.2%) were the leading causes of injury among pitchers, whereas noncontact (36.2%) and overuse (17.2%) were the leading causes of injury among field players. Pitchers were most likely to be injured while pitching (55.9%) and fielding (38.2%), whereas field players were most likely to be injured while batting (31.0%) and base running (31.0%).CONCLUSIONS: The current findings indicate that the characteristics of the injuries of KBO players differ by position, emphasizing the importance of a position-specific injury prevention program.
The Prolyl Hydroxylase Domain 2 (PHD2) Deficiency Enhances Maximal Exercise Capacity
Authors: Shin Junchul
Published: March 2024

PURPOSE: Hypoxic training is beneficial for improving endurance performance. Hypoxia-inducible factor (HIF) is a key transcription factor that regulates the hypoxic-responsive pathway. Stabilization of HIF by inactivating prolyl hydroxylase domain protein 2 (PHD2) under low oxygen tension, triggers angiogenesis, erythropoiesis, and glycolysis. Glycolytic capacity is essential to perform anaerobic exercise. This study aims to verify whether the upregulation of glycolytic metabolism under the hypoxic-responsive pathway enhances exercise capacity.METHODS: We employed tamoxifen-inducible conditional PHD2 knock-out (KO) mice that exhibited stabilized HIF-alpha. To evaluate anaerobic exercise capacity, a rodent treadmill exercise test was performed. RNA sequencing (RNA-seq) analysis was conducted using C2C12 myoblasts after PHD2 siRNA transfection.RESULTS: PHD2KO mice exhibited increased red blood cell counts, hemoglobin, and hematocrit values, along with enhanced maximal exercise performance compared to littermate wild-type (WT) mice. PHD2 deficiency promoted maximal exercise capacity and resulted in lower blood lactate levels. RNAseq analysis revealed that PHD2-deficient myoblasts increased the expression of genes related to glycolysis, gluconeogenesis, and muscle contraction.CONCLUSIONS: These findings suggest that PHD2 deficiency-induced activation of the hypoxic-responsive pathway enhances maximal exercise capacity.
Effects of Treadmill Exercise on Autistic Behavior and Prefrontal Cortical SHANK Receptors in Autism Spectrum Disorder Model Mice
Authors: Kim Kyeong-Ri , Kim Tae-Kyung , Cho Joon-Yong
Published: March 2024

PURPOSE: The first aim of this study is to change autistic behavior in Shank3B Knock-Out (KO) mice through treadmill exercise (TD), and the second aim is to alter SHANK protein receptors in the prefrontal cortex (PFC) of mice through TD.METHODS: Male mice were divided into Control (11-week-old, n=8), Control+TD (n=8), Shank3B KO (n=8), and Shank3B KO+TD (n=8). Control and Shank3B KO mice were exercised using TD for 2 weeks for 30 minutes each to observe the effects of exercise.RESULTS: Compared to the control group (C57BL/6J), Shank3B KO mice showed excessive self-grooming behavior; however, TD reduced repetitive behavior (p<.05). The effect of TD was also seen in the behavior of Shank3B KO mice evaluated by measuring social interaction time using the two-chamber social behavior test and socio-sexual behavior test (p<.05 compared to control). Differences were found in C57BL/6J and Shank3B KO mice by assessing proteins such as GluR2, Homer1, phosphorylated GSK-3α/β, and phosphorylated Akt1 in the PFC. The results suggested that TD yielded better outcomes in Shank3B KO+TD mice than in Shank3B KO mice.CONCLUSIONS: TD positively affected behavioral changes in repetitive behavior and social interaction defects in autism spectrum disorder (ASD) model mice. Alterations were also observed in the SHANK glutamate receptor and SHANK sub-signal transporter phosphorylation protein. This suggests that TD is an effective way to improve autistic behavior in ASD. However, further research is necessary to clarify the effects of TD by studying the underlying mechanisms and changes in SHANK proteins and other factors.
Teoria e Prática nos Projetos Pedagógicos de Cursos de Licenciatura em Matemática: do que estamos falando quando usamos essas expressões na formação de professores?

Published: March 2024

Resumo: O estudo apresenta e problematiza significados de teoria e prática que se produzem no campo de formação de professores de Matemática. Questiona quais significados de teoria e prática estão descritos nos Projetos Pedagógicos de Cursos (PPC) de Licenciatura em Matemática e quais movimentos podem ser mobilizados na perspectiva da indissociabilidade de teoria e prática. A pesquisa é de natureza qualitativa, considerando dois PPC de Licenciatura em Matemática de uma instituição federal de ensino do sul do Brasil. A análise empreendida mostra os significados de teoria e prática imbricados no uso alargado da expressão prática como aplicação da realidade, na prescritividade imposta pela reflexão sobre a prática e nas interlocuções da teoria, quando relacionada à sustentação e ao embasamento da prática. São propostos movimentos na perspectiva de superação da dicotomia teoria e prática com a apresentação dos significados dessas expressões nos PPC e revisão das adjetivações, o que tende a borrar as fronteiras entre essa divisão.

Resumo: Ao longo da história, os surdos foram privados do acesso às áreas das ciências da natureza, seja pelo tardio consenso quanto à forma como deveriam se comunicar, seja pela crença limitante de que não estavam aptos para tais habilidades. O objetivo deste artigo é discutir a importância da criação de novos sinais e termos científicos para a área das ciências. Realizamos uma pesquisa exploratória e qualitativa, na qual buscamos sinais e termos de modo a manter a fidelidade dos conceitos abordados na exposição de um centro de ciências itinerante. Como resultado, encontramos uma escassez de sinais de parte considerável dos conceitos tratados e a falta de padronização entre os que estão disponíveis e em uso. Concluímos que é necessário maior unidade entre grupos de pesquisa para o desenvolvimento de glossários de ciências em Língua Brasileira de Sinais para que os surdos possam abstrair o conhecimento mais facilmente.

Published: March 2024

Abstract The institutionalization of participation is a topic that has been discussed in different ways over the last few decades. There are many diverse aspects of the agricultural sector and rural communities that can be identified and used to bring about a major change in agriculture. Community supported agriculture (CSA) is one of the participatory and sustainable approaches that can be used in this regard. CSA is a relatively new socioeconomic model for producing food materials, increasing food security, improving the quality of food materials and conserving agricultural land, plants and animals. This research aimed to design a CSA model that was operationalized in Markazi province, Iran, with the aim of increasing food security. It was a survey study applied through a questionnaire. The statistical population (N=110) consisted of all active farmers in Ghazel Dareh village who were selected through the census method. The necessary information was collected through a questionnaire (84 of which were completed and returned) and analyzed using SPSS v. 25 and LISREL. The results showed that economic, socio-institutional, policy-making, educational and infrastructural factors significantly influenced the development of CSA. Infrastructural and socio-institutional factors with impact factors of 0.88 and 0.54 had the largest and smallest effect on CSA, respectively. Finally, since all impact factors were positive, we can say that improving each of these factors could improve the development of CSA in the study area.

Published: March 2024

Abstract Accumulation of heavy metals in soil can lead to the deterioration of soil quality, reduce soil fertility and crop yields, and thus threaten human and animal health. The study aimed to assess the potential ecological risk of heavy metal contamination of agricultural soils in Kazakhstan. The study was carried out in 2021 on the soils of the Zhdanovskoye owner-operated farm in the Sokolovsko-Sarybai district of the Kostanay region. The quantitative content of heavy metals, such as lead (Pb), mercury (Hg), arsenic (As), and cadmium (Cd), was determined, and concentrations of trace elements, such as zinc (Zn), copper (Cu), iron (Fe), and manganese (Mn), were calculated for the considered contaminated lands. The potential ecological risk index (RI) proposed by L. Hakanson was used in the study concerning heavy metal contamination of soil. As a result, the presence of trace elements and heavy metals in the considered areas of the Kostanay region was shown. The RI values for all sites ranged from 137 to 447, corresponding to the level of ecological risk grading from low to high. The average RI for As, Cd, Hg, Pb, Zn, Ni, and Cu amounted to 328, which indicates a high ecological risk. Detected levels of As, Cd, Zn, and Pb in long-term abandoned mining areas were well above national thresholds, indicating the impending need to fully investigate and assess the suitability of the land for further agricultural use. The availability of such data will allow predicting cluster-based development of processing infrastructures in the vicinity of agricultural lands.

Authors: Vieira Glacy Sabra , Martinez Maria Carmen , Cardoso Maria Regina Alves
Published: March 2024

ABSTRACT Objective: To compare cancer mortality among workers exposed to gamma and X radiation and the general population of the city of São Paulo, as well as that of the subgroup monitored with those not monitored for gamma and X radiation in a work unit with ionizing radiation based in the city of São Paulo. Methods: Between 2016 and 2021, a retrospective open cohort study was carried out with workers who were employed from 08/31/1956 to 12/31/2016 based on data collected at the company and in official institutions. Standardized mortality ratios (SMR) were calculated by sex, age and calendar period of cancers grouped according to type, risk factor and organ system in two analyses: in the external analysis, the mortality of the study population was compared with that of the general population of the city of São Paulo; In the internal analysis, the mortality of the monitored subgroup was compared with that of the subgroup not monitored for gamma and X radiation. Results: The external mortality analysis showed SMR=0.224 (95%CI 0.208–0.240) and the healthy worker effect, while the internal mortality analysis showed SMR=0.685 (95%CI 0.618–0.758). Conclusion: This study showed lower cancer mortality among exposed workers when compared to mortality in the general population and the healthy worker effect. Among workers monitored for gamma and X radiation, cancer mortality was lower when compared to those not monitored.

Published: March 2024

ABSTRACT Objective: To verify the association between sociodemographic factors and the time until the occurrence of new cases of COVID-19 and positive tests for SARS-CoV-2 in Brazil, during the period from May to November 2020, based on a cohort of Brazilians participating in the COVID-19 National Household Sample Survey. Methods: A concurrent and closed cohort was created using monthly data from the PNAD COVID-19, carried out via telephone survey. A new case was defined based on the report of the occurrence of a flu-like syndrome, associated with loss of smell or taste; and positivity was defined based on the report of a positive test, among those who reported having been tested. Cox regression models were applied to verify associations. The analyzes took into account sample weighting, calibrated for age, gender and education distribution. Results: The cumulative incidence of cases in the overall fixed cohort was 2.4%, while that of positive tests in the fixed tested cohort was 27.1%. Higher incidences were observed in the North region, in females, in residents of urban areas and in individuals with black skin color. New positive tests occurred more frequently in individuals with less education and healthcare workers. Conclusion: The importance of prospective national surveys is highlighted, contributing to detailed analyzes of social inequalities in reports focused on public health policies.

Conclusão: Foram observados riscos desiguais entre os estratos populacionais comparados. Destaca-se a importância da realização de inquéritos nacionais prospectivos na investigação de iniquidades em saúde.
ON THE RELATIONSHIPS BETWEEN SYLLABLES AND MUSICAL NOTES IN SUNG WORDS IN BRAZILIAN PORTUGUESE
Authors: CARMO JR José Roberto do
Published: March 2024

ABSTRACT Sung words often present prosodically ungrammatical structures. Such structures cannot be described exclusively on the basis of the linguistic environment in which they occur. Ungrammaticality manifests itself in the actualisation of phonological processes in environments in which such processes would be blocked and, conversely, in its blockage in environments in which their actualisation would be expected. The aim of this paper is to describe this behaviour of sung words that contrasts with that of spoken words. We shall initially introduce examples that illustrate the extent of the problem as well as its ubiquity. Next, we shall argue that the observed ungrammaticality can be explained on the hypothesis that the correspondence between text and melody in sung words is regulated by well-formed conditions. One of these conditions — which we call Metrical Pairing — establishes that the relationship between note and syllable is always bijective, that is (I) each and every note in a melody must be assigned to one and only one syllable, and (II) each and every syllable in a string must be paired with one and only one note. The observance of this condition for well-formedness of sung words explains both the actualisation and the blockage of phonological processes that diverge from the phonology of spoken Portuguese.
Children with Verbal Restrictions and the Concept of Intercomprehension and Multimodality in Speech-Language Therapy: A Case Study
Authors: Silva Cristiane Alves , Santana Ana Paula
Published: March 2024

ABSTRACT This article aims to analyze the process of mutual understanding from the perspective of Discursive Neurolinguistics. As a methodology, a case study was carried out on a child with a linguistic profile of verbal restriction, which concerns the dimension of utterances involving words and their morphology. Data interpretation was based on the Bakhtinian perspective, which addresses ‘understanding’ as an active-responsive process and meaning as emerging from the relationship between utterances. The results showed that the interlocutors’ common ground allowed the joint construction of meaning even in the face of verbal restrictions, and aspects such as nonverbal elements and the recognition of the child’s active-responsive role also favored mutual understanding. As a conclusion, the attention to different multimodal resources as legitimate modes of expression allows children with verbal restrictions to fulfill the role of “speakers” regardless of their modes of expression.
Religion and Politics: Clash of Meanings about the Evangelical Faith in Pastors’ Posts on Instagram
Authors: Brito Cristiane Carvalho de Paula , França Thyago Madeira
Published: March 2024

ABSTRACT This work aims to reflect on possible meanings for the evangelical faith based on utterances produced by three evangelical ministers in their social networks when they enunciate on themes that are linked, directly or indirectly, to political agendas. Based on the theoretical scope of studies in Applied Linguistics and on Bakhtinian conceptions of language, our analyzes point to three predominant meanings, which mean the evangelical faith as: i) reaffirmation of identity; ii) exercise of otherness and respect to the other; and iii) political practice. Such meanings demonstrate that there are contradictions within the religious discursivity, which allows the beating between hate speeches and respect and empathy ones within the realm of the evangelical faith. Thus, looking for cracks in religious discourse that oppose fundamentalist and authoritarian discourses is an ethical duty of a religious leader who recognizes his social and discursive role as influential in taking positions and, therefore, in the lives of the members of their congregation.

On the road with Uber: an ethnography
Authors: Souza Ilan Fonseca de
Published: March 2024

Abstract The article aims to investigate the work management strategies undertaken by Uber in relation to its drivers. Using the observant participation method, the researcher drove a car performing races mediated by the platform for a period of four months in the Metropolitan Region of Salvador, Bahia. The company operates with a management strategy that encourages false entrepreneurship and, at the same time, hides an employment relationship: dissimulation. To do so, it makes use of tactics such as encouragement, task management, pedagogism, fraud, risk-sharing and obscurantism, as ethnography has managed to identify.
“Se a gente tivesse direito, não teria necessidade de estar fazendo manifestação pra nada”: a luta das marisqueiras de Farol de São Thomé, RJ - Brasil contra estereótipos de gênero em políticas públicas
Authors: Huguenin Fernanda Pacheco
Published: March 2024

Resumo O trabalho desenvolvido pelas mulheres presentes na cadeia produtiva da pesca artesanal é historicamente invisível, seja no prestígio interno das comunidades, na gestão pesqueira ou na identificação legal das trabalhadoras. A invisibilidade feminina incorre, inclusive, na restrição a direitos de seguridade social, como o denominado Defeso. Ao longo dos anos de 2018 a 2022, a pesquisa investigou a luta das marisqueiras de Farol de São Thomé, comunidade situada no Norte Fluminense, RJ - Brasil, contra estereótipos de gênero presentes na política pública intitulada Projeto Bolsa Cidadão (PBC), instituída no município de Campos dos Goytacazes/RJ de 2000 a 2021. A partir de técnicas metodológicas qualitativas, como a observação direta em trabalho de campo, entrevistas semiestruturadas e organização de grupo focal, bem como de uma epistemologia jurídico-antropológica crítica, o texto busca refletir sobre as dimensões da redistribuição, do reconhecimento e da participação feminina no âmbito da pesca artesanal e conclui que bloqueios discriminatórios restringem ou mesmo excluem as trabalhadoras do acesso a programas sociais. Este artigo é resultado de pesquisa financiada pelo Projeto de Educação Ambiental (PEA) Pescarte, que é uma medida de mitigação exigida pelo Licenciamento Ambiental Federal, conduzido pelo IBAMA.

Resumo Essa escritura é resultante de estudos e pesquisas sobre a circulação de impressos no século XIX, na província da Paraíba, na perspectiva de compreender o espaço ocupado por eles e pelo livro na transmissão da cultura. Esses objetos carregam significações de um tempo e lugar, fomentando os sentidos que orientam uma sociedade. O objetivo é visibilizar os livros de caráter religioso que circularam na província da Paraíba, em 1864, nos anúncios do jornal O Publicador, de modo a educar moral e religiosamente os leitores. Para tanto, utilizou-se de fontes escritas, tomando artigos da Carta Constitucional de 1824 e a consulta a impressos. Os escritos de Roger Chartier, Michel Foucault e Robert Darnton contribuíram para a compreensão da força educativa dos livros religiosos na sociedade paraibana imperial. Esse objeto cultural fomentou estratégias para manutenção no poder dos grupos dominantes.
Parliamentary Speeches, Political Economy, and the Corn Laws (1839-1846)
Authors: Arthmar Rogério
Published: March 2024

ABSTRACT Debates in the British House of Commons between 1839 and 1946 revealed four distinct positions on the controversial Corn Laws. The Radicals, led by Richard Cobden, fought for overall free trade. The moderate Whigs, headed by Lord John Russell, leaned toward a fixed duty on imported corn. The Conservative Peelites, rallied behind Robert Peel, supported the prevailing sliding-scale system, while the landed Tories, who coalesced around Lord George Bentinck, wished protection all around. This article analyzes how the principles of political economy got entangled with political considerations in the speeches delivered by the leaders of each parliamentary faction. It concludes by highlighting the crucial role of political economy, especially the free trade doctrine, along with material evidence and historical precedent, as the key concurring factors in the repeal of the Corn Laws in 1846.

Published: March 2024

ABSTRACT Objective: To understand obstetric nurses’ challenges in managing work and care in normal birth centers. Method: A qualitative study was carried out in normal birth centers in Ceará, Brazil. Thirteen nurses and obstetric care coordinators were interviewed between April and July 2020. The thematic categories were organized in Nvivo 12 Pro® software and discussed using the theoretical-philosophical framework of the Sociology of Professions. Results: care practices, such as comfort massages, are carried out in conjunction with elements of work management, such as the sizing of the nursing team. It emerged that there are important skills for acting as autonomy and leadership of the nursing team, but elements such as fragile trust and interaction limit the full development of activities. Final considerations: there are challenges for management and care in normal birth centers, such as consolidating autonomy and building trust with the health team.
A (RE)VIEW OF DYNAMIC CAPABILITIES: ORIGINS AND FUTURE DEVELOPMENTS
Authors: Bitencourt Claudia , Müller Neto Hugo Fridolino , Zanandrea Gabriela
Published: March 2024

ABSTRACT This paper aims to map out how the field of dynamic capabilities has developed since the seminal studies by Teece et al. (1997) and Eisenhardt and Martin (2000). We identified 10,838 papers and used the Latent Dirichlet Allocation algorithm for topic modeling. We conducted two analyses: the first was based on the temporality and characteristics of the studies; the second was interpretative and based on the network of theoretical concepts. Results indicate an approximation between the ideas of the two seminal studies, which were initially viewed as opposite. We observe a movement to value relational issues, following a collective construction path, and paying less attention to the firm itself. Overall, we were able to understand the consolidation of the dynamic capabilities field; understand the core elements involved in the development of dynamic capabilities; set out the original and current concepts of dynamic capabilities; and indicate tendencies and a possible future research agenda.

ABSTRACT The quality of seedlings is a determining factor to guarantee the greatest potential crop productivity. The aim of this study was to evaluate the quality of lettuce seedlings grown in floating system, in relation to cell volume and electrical conductivity of the nutrient solution. The experiment was carried out in a completely randomized design, in a 3 x 2 x 4 factorial scheme, with three replicates. Seedlings of three lettuce cultivars (Great Lakes 659, Elba and Creta) were produced in two types of trays (128 and 200 cells) and fertigated with nutrient solutions (four electrical conductivities of 1.0; 1.5; 2.0 and 2.5 dS/m). The variables evaluated were: height, number of leaves, length of the main root, stem diameter, leaf area, total dry mass and shoot dry mass/roots dry mass (MSPA/MSR) ratio. Great Lakes 659 showed more vigorous seedlings for most of the evaluated variables. The three cultivars produced higher quality seedlings when cultivated in trays with 128 cells, with the EC of the nutrient solution ranging from 1.8 to 2.0 dS/m.

ABSTRACT This study aimed to determine the chemical, physical-chemical properties and agronomic efficiency of fermented composts formulated with agro-industrial wastes and tephrosia (Tephrosia sinapou) phytomass (TS) in arugula fertilization. The experiment was carried out in two phases, using wheat bran (FT), sugarcane bagasse (BC), TS phytomass and malt bagasse (BM) in the compound formulations. The first stage consisted of evaluating the chemical and physical-chemical properties in a completely randomized experimental design with 9 treatments (60TS+30FT+10BC; 60TS+30BM+10BC; 60TS+20FT+20BC; 60TS+20BM+20BC; 60TS+ 10FT+30BC; 60TS+10BM+30BC; 60TS+40FT; 60TS+40BM; 60TS+40BC) and four replicates. The second stage consisted of evaluating the agronomic efficiency of the formulations 60TS+40FT, 60TS+10FT+30BC, 60TS+40BM, 60TS+10BM+30BC and 60TS+40BC in arugula crop and a control treatment (without fertilizer). The fermented composts showed suitable chemical and physical-chemical properties for being used as fertilizers. Tephrosia phytomass has the potential for producing fermented composts, whose combination with 40% FT or BM, respectively, provided increases in N, P, K, Ca and Mg uptake, and in arugula productivity of 129,14% and 127.32% higher than the control (without any organic fertilizer)
Analysis of adequacy of recycling the São Paulo Metropolitan Ring Road concrete pavement as new pavement
Authors: Balbo José Tadeu , Tseng Ester
Published: March 2024

Abstract The west section of the Governor Mário Covas São Paulo Metropolitan Road Ring was opened to traffic in 2002. The original pavement was a jointed plain concrete pavement with dowelled joints and a design flexural strength (or modulus of rupture) of 4.5 MPa. Premature failure of the concrete slabs was observed not only by engineers and users, but also reported by the media. Concrete slabs soon started being demolished and replaced. Many of the removed slabs were taken to a nearby recycling plant for crushing. However, the resulting recycled concrete aggregate was not used in the manufacturing of the new slabs. There were concerns that the potential presence of detrimental chemical substances had caused the early deterioration of the slabs. If that were true, using recycled aggregates obtained from the original concrete could result in the same issues in the new mix. This paper describes a feasibility study on recycling the original concrete for use as aggregate in new concrete slabs. The first goal was to verify the presence of fluorite as detrimental substance in the existing concrete because there was a suspicion among concrete technologists engaged on mixture design during the construction. Chemical analysis using X-ray fluorescence spectrometry did not show the presence of chemical components detrimental to concrete durability. Therefore, the second goal was to accept the material for recycling and discuss mix proportions, strength, stiffness, fracture toughness, and fatigue. Although some of the concrete properties were affected by the inclusion of recycled aggregates in the mix, the results indicate that it is possible to use recycled aggregates produced from the original concrete to cast new concrete slabs, however requiring greater thicknesses. The fatigue performance of recycled mixtures points out the demand for thicker and eventually more expansive design solutions.

Objetivo. El objetivo es revisar la evidencia científica actual sobre los efectos fisiológicos del método canguro, explorar las barreras y facilitadores para su aplicación, además de identificar áreas de conocimiento aún no exploradas. Materiales y métodos. Revisión Integrativa, que incluyó estudios de revisión cuantitativos y cualitativos, en las bases de datos PubMed, Scopus, Web of Science y Cochrane, sin restricción de idioma. La valoración crítica de los estudios se realizó con la herramienta del Joanna Briggs Institute. Resultados. Se analizaron 16 estudios, entre los cuales se encontró evidencia que respalda la eficacia del método canguro en la mejora de diversos parámetros fisiológicos del neonato. Entre estos parámetros se encuentran la frecuencia cardíaca, la temperatura corporal y la saturación de oxígeno. Sin embargo, los resultados son heterogéneos. Las principales barreras para la implementación del método canguro incluyen: restricciones de las horas de visita, carga de trabajo del personal sanitario, creencias culturales negativas, falta de información y empoderamiento de las madres, además de la limitada participación de los padres. Conclusiones. El método canguro tiene un impacto positivo en el desarrollo los neonatos prematuros o de bajo peso. Sin embargo, su implementación se ve afectada por diversos factores socioculturales. Futuras investigaciones deben identificar los efectos reales sobre los parámetros fisiológicos del neonato.  Se necesitan estudios cualitativos para comprender mejor las perspectivas de las familias, de los equipos médicos, y así desarrollar estrategias de adaptación cultural que optimicen la aplicación del este método en diferentes contextos.

Aims. Rolandic (RE), childhood absence (CAE) and juvenile myoclonic (JME) epilepsy encompass centrotemporal sharp waves, 3‐Hz spike waves and >3‐Hz spike or polyspike waves, respectively. Evidence abounds for genetic roles in all three syndromes, yet involved genes for the vast majority of patients remain unknown. It has long been proposed that while each disease is genetically complex, its specific EEG trait may represent a genetically simpler endophenotype. This meta‐analysis of the literature focuses on the frequency of EEG traits in clinically unaffected first‐degree relatives towards determining inheritance patterns of the EEG endophenotypes.

Methods. We used the Preferred Reporting Items for Systematic Review and Meta‐Analysis for protocols (PRISMA‐P) and searched Medline, EMBASE, CINHAL and the Cochrane Central Register of Controlled Trials.

Results. Following extensive screening, 15 studies were included with a total of 3,858 asymptomatic relatives. The prevalence of ‘abnormal’ EEG waves was 21%, 42% and 33% for JME, CAE and RE, respectively, close to what would be expected based on Mendelian inheritance. However, breaking down the reported EEG abnormalities, most consisted not of the respective EEG signature traits ‐prevalences of which were as low as 5%‐ but of non‐specific EEG ‘abnormalities’/variants.

Conclusions. Prevalence of non‐specific EEG ‘abnormalities’/variants in the general population ranges from 0.1 to 10%. Underlying this 100‐fold‐wide range is a spectrum of what is considered ‘abnormal’ or variant. The prevalences of ‘abnormalities’/variants in asymptomatic siblings in RE, CAE and JME significantly exceed even the highest value in the general population and fall within Mendelian expectations. These results suggest that EEG ‘abnormalities’/variants shared with the general population are enriched in the three syndromes and are endophenotypes inherited in a genetically simple near‐Mendelian fashion. Future work with modern EEG variant definitions should uncover genetic variants contributing to neuronal hypersynchrony in epilepsy.
Evolution of concepts in epilepsy surgery*
Authors: Engel Jerome
Published: March 2024

At the time of the first meeting of the International League Against Epilepsy (ILAE) in 1909, surgical treatment for epilepsy had been accepted as an alternative therapy for over two decades, but was rarely practiced, considered a last resort for carefully selected patients. Localization was based on ictal semiology and identification of a structural lesion. Very few papers on epilepsy surgery were presented at ILAE meetings or published in Epilepsia during the first half of the 20th century. A modest explosion in interest in epilepsy surgery at mid‐century resulted from recognition that “invisible” epileptogenic lesions could be identified by EEG, especially for temporal lobe epilepsy. Epilepsy surgery received a second boost in popularity toward the end of the 20th century with the advent of structural and functional neuroimaging, and the number of epilepsy centers worldwide doubled between the first Palm Desert conference in 1986 and the second Palm Desert conference in 1992. Neuroimaging also helped to increase application of surgical treatment to infants and young children with severe epilepsies. Epilepsy surgery was accepted as standard of care for drug‐resistant focal epilepsy and was well‐represented at international ILAE congresses and in Epilepsia. Advances continue into the 21st century with the introduction of laser ablation, and palliative neuromodulation approaches, which have greatly increased the population of patients who can benefit from surgery. Modern presurgical evaluation techniques have also made surgical treatment possible in many countries with limited resources. Three randomized control trials now have definitively proved the safety and efficacy of epilepsy surgery, however, this alternative therapy remains under‐utilized even in the industrialized world, where less than 1% of potential candidates are being referred to epilepsy centers. Furthermore, those who are referred receive surgery an average of 20 years after onset of epilepsy, often too late to avoid irreversible disability. The major challenges in realizing the full potential of epilepsy surgery, therefore, are not as much in the continued improvement of the treatment itself, as they are in addressing the treatment gap that is preventing appropriate patients from being referred to full‐service epilepsy centers.
Prosodically determined coordinator placement in Yorùbá

Published: March 2024

In this paper, we look at the properties of the clausal coordinator sì in Yorùbá. We will show that despite its unusual surface position in the middle field of the second conjunct, the element should still be treated as a proper coordinator and not, as sometimes claimed, as an adverb. We then go on to fully describe the distribution of sì in simple clauses as well as in complex constructions involving focus movement, adverbial or relative clauses. Based on these configurations, we argue that a search for a uniform syntactic position of sì is bound to be unsuccessful. Rather, we claim that the uniform underlying factor in all of these constructions is that sì always right-attaches to the first phonological phrase of the second conjunct clause irrespective of syntactic constituents or islands. We provide evidence for this claim from various phonological processes such as (i) phonological fusion, (ii) the association of floating tones, (iii) assimilation, (iv) tonal OCP-effects, and (v) allomorphy. The present study thus not only solves a curious language-specific puzzle in Yorùbá but also provides a convincing case of prosodically driven clitic displacement to a position after the first phonological/prosodic phrase. In doing so, it falls nicely into emerging typologies of clitic placement patterns in the world’s languages.

The import substitution paradigm requires creating new production facilities and developing existing ones. One way to achieve the goals of efficient production could be perfecting organization of complex objects, ensuring ability of interrelated parts of the production system in the process of interaction to not only maintain itself, but also develop in conditions determined by the state of the suprasystem and the current environment. The multiplicity of characteristics of the external and current environment of economic objects makes it impossible to put forth a single criterion to assess whether the level of organization of the system is in line with its development strategy. This assessment of alignment of the organization of the system with the major goals set by the strategy should be based on the methods of system analysis and the corresponding methodology.
Assessing significance of the field of processes and the functions implementing them makes it possible to solve a practical task of improving the organizational structure via updating the most significant functions by using information technology, which ensures efficient use of resources of the subsystem. At the same time, a viable sequence of stages in the development of information systems can be identified, thus minimizing expenditure inefficiency of their launch.
Own Brands of Food Retail under Sanctions
Authors: Fedotov Andrey
Published: March 2024

The Russian food retail has faced a number of issues caused by the aggravation of the geopolitical situation and the subsequent imposition of sanctions against Russia. International logistics companies have withdrawn from the market resulting in disruption of logistics supply chains. Due to the sanctions against the Russian banking sector, it has been increasingly difficult to pay for imported goods. Purchasing power has lowered, as multiple key suppliers of consumer goods withdrew from the Russian market and there are problems of importing raw materials and packaging for goods in this segment. Logistical issues forced food retailers to restructure their assortment strategy. The article looks into the issues of the Russian companies introducing their own brands in their operation in the context of the formation of a new trade policy of grocery retail. It is pointed out that both the network retail and the manufacturer will benefit from introducing their own brands. Based on the study and analysis of the latest regulations and sources of modern literature, a hypothesis has been proposed, stating that the policy of using one’s own brand in food chain retail will lead to increased sales volumes and minimized costs of promotion and display. Based on statistical and factor analysis methods, a forecast of the development of the Russian food retail is proposed within the framework of the strategy of introducing business’s own brands.
