O presente estudo pretende analisar as produções do conhecimento sobre lazer e sua relação com a educação e a Educação Física, com o objetivo de levantar nexos e contradições que estabelecem a realidade desses estudos no Brasil, a fim de reconhecer que possibilidades de contribuições significativas atendem aos interesses da classe trabalhadora. Nossa discussão teórica envolve autores que desenvolveram seus estudos em torno do nosso objeto de investigação: o lazer e a lógica de produção capitalista. Partimos da compreensão do lazer, desde a apreensão histórica, até a concepção de lazer proposta pelo sistema econômico - produtivo da sociedade na atualidade. Propomos nesse estudo uma pesquisa exploratória bibliográfica. Para isso, foram selecionadas produções acadêmicas relevantes para a área. Para tanto, busca-se nesse estudo uma análise do que foi publicado sobre lazer e sua relação com a educação e a Educação Física, entendendo o lazer como fenômeno da práxis social produzida pela cultura humana em relação à forma com que os seres produzem a existência. Por entender que a escola é um espaço social de apreensão da cultura e o lazer sendo parte dessa cultura, se faz necessário reconhecer em que bases se apresentam os estudos que estabelecem relações e nexos sobre lazer e educação, considerando uma problemática do campo de conhecimento de Educação Física. Portanto, busca-se reconhecer as possibilidades significativas do lazer que atendam às necessidades da classe trabalhadora, à luz de uma teoria do conhecimento que viabilize a compreensão do lazer como prática social inerente à vida humana, em sua totalidade histórica, reconhecendo seus determinantes econômico-social e político. Os resultados apontam como o projeto histórico capitalista condiciona o trabalhador com relação às práticas do lazer, uma vez que este só irá se envolver nas práticas inerentes ao lazer a partir do momento que se submeter a uma exaustiva jornada de trabalho, para receber uma quantia mínima e consequentemente fortalecer a classe hegemônica.

Published: June 2024

Tower solar energy achieves high efficiency solar heat conversion by virtue of the advantages of concentrating light and collecting heat. In this paper, a spatial model of the sun's incident light collection and the mirror's reflected light collection is established. The sun's orientation at different times is investigated and the optical efficiency of each heliostat is obtained. The average of the optical efficiency of the heliostat field in the case of the collection of incoming solar rays is obtained as the optical efficiency of the heliostat field under the irradiation of the sun cone. Firstly, based on the latitude and longitude of the heliostat field, the altitude Angle and azimuth Angle of the sun at different times are calculated. Secondly, according to the position coordinates of heliostatic center and absorption tower in geodetic coordinate system, the normal direct radiation irradiance DNI and atmospheric transmittance of all heliostatic fields are determined . Subsequently, a number of mirror coordinate systems are established to calculate the direction vector of the sun incident light and the direction vector of the mirror center pointing to the collector center, and obtain the incidence Angle, mirror normal vector, helioscope pitch Angle, helioscope azimuth Angle and cosine efficiency of each helioscope. According to this, the ray tracing method is used to calculate the shadow blocking efficiency of the mirror. Finally, the HFLCAL model is used to calculate the collector truncation efficiency , and the average annual optical efficiency of the heliostat field is 0.313067, the average annual output work and heat rate is 19.266981MW and the average annual output power per unit mirror area is 0.306701kw/m2.

Published: June 2024

In order to solve the problem of designing the shortest line of multi-beam sounding in the specified sea area, a multi-parallel sounding model based on the plane beam equation is constructed for the first time. At the same time, in order to find the shortest exploration line in the unknown sea area, we divide the optional directions of the survey line into three different cases that can cover all the optional directions, namely, the Angle between the direction of the survey line and the projection of the normal direction of the seabed slope on the horizontal plane β = 0°, 90°, 180°, 270°. Compared with other papers that solve similar problems, we can make a comparison in different situations by quantitative analysis of the plane beam equation established in different directions, considering that the overlap rate of multi-beam sounding under the redefinition of three-dimensional model should not be too high, and the need to minimize the area redundancy caused by the exploration of unnecessary sea areas. The direction corresponding to the shortest measurement line is obtained. After determining the direction, the specific shortest line and its shortest length can be obtained according to the relevant knowledge of spatial analytic geometry and algebra. In the problem studied in this paper, space analytic geometry and the use of algebraic related knowledge with refined steps can finally get more accurate results, and usually better than the performance of the applied algorithm, so we adopt this method for modeling and solving.
día que el ilustre claustro de San Marcos juró la independencia rompiendo sus juramentos de obediencia a la Constitución de Cádiz
Authors: González Bolaños Jorge Federico 
Published: June 2024

Tras su promulgación, se decretó que la Constitución de Cádiz sea juramentada por autoridades y corporaciones en 1812 y 1820. La obediencia a la Constitución de Cádiz fue juramentada dos veces por el ilustre claustro de San Marcos, que después prestaría su solemne juramento por la independencia del Perú. Las actas de juramento serán instrumentos políticos, exigidas como pruebas escritas de lealtad obediente al régimen imperante. El Protectorado decretaría en agosto de 1821 la abolición de la Constitución de Cádiz enfatizando el desglose de las actas de juramento gaditano para reemplazarlas por las actas del nuevo juramento por la independencia.

Determination of the time of refractive stability after uneventful phacoemulsification in Indian eyes
Authors: Nanda Ashok Kumar , Panda Bijnya Birajita , Swain Asish , Balakrishnan Logesh 
Published: June 2024

BACKGROUND
Knowledge about refractive stabilization and the accuracy of postoperative refractive error measurements are crucial for improved patient outcomes after phacoemulsification. Existing guidelines typically recommend waiting 4-6 wk before prescribing corrective lenses. Our research focused on identifying factors that influence refractive errors in the early stages of post-cataract surgery, thus contributing to the existing literature on this topic.
AIM
To investigate the time required for refraction stability after uneventful phacoemulsification surgery.
METHODS
We compared the variation and statistical significance of the difference in spherical, cylindrical components, and the spherical equivalent between the 1- and 6-wk follow-up period in a group of 257 eyes that underwent uneventful phacoemulsification with foldable intraocular lens implantation, all performed by a single experienced surgeon. The Wilcoxon-Signed Rank Test was utilized to assess the magnitude of the change and determine its statistical significance. The refractive stability was defined as the point at which the change in spherical equivalent was within ± 0.5 dioptres for two consecutive visits.
RESULTS
The average age of the patients was 64.9 ± 8.9 yr. The differences observed in both the visits in spherical power (0.1 ± 0.2), cylinder power (0.3 ± 0.4), and spherical equivalent (0.2 ± 0.2) were minimal and not statistically significant. The majority of eyes (93.4%) achieved refractive stability within 6 wk after the surgery. The cylindrical power differed between age groups at the 6th wk post-operative and the difference was statistically significant (P value 0.013). There were no significant differences in refractive stability when considering sex and axial length.
CONCLUSION
Phacoemulsification with foldable intraocular lens implantation results in no significant changes in refraction for the majority of cases during the 6-wk follow-up period. Therefore, a spectacle prescription can be given at the completion of 1 wk.
Lessons from overtly-headed exclamatives in Spanish varieties
Authors: Villa-García Julio 
Published: June 2024

Inverting wh-exclamative sentences with an overt complementizer in languages like Spanish pose a serious challenge to traditional accounts of obligatory subject-verb inversion. Such analyses assume either T-to-C movement or Spec,TP as an A-bar position capable of hosting wh-phrases and subjects alike. The optional presence of a complementizer in the head of CP in exclamatives prevents the verb from moving to CP, which argues against an analysis of inversion wherein the verb moves to Cº. Regarding the Spec,TP-as-an-A-bar-position account, if the wh-phrase sits in Spec,TP and competes with the subject for that position, the presence of a complementizer below wh-phrases in exclamatives is then rather mysterious, since que ‘that’ is standardly assumed to signal the presence of CP structure –not IP/TP structure. However, for those cases in which the complementizer occurs, a combined approach consisting of a modification of the Spec,TP-as-an-A-bar-position account which assumes further movement of the exclamative wh-phrase to a CP-related/left-peripheral projection headed by the complementizer is shown to be empirically superior to the competing proposals on the market. Furthermore, dialect data show that the presence of que is sensitive to the type of exclamative phrase in its specifier. The inverting exclamative data with overt que also indicate that it is the full projection consisting of the exclamative wh-phrase in the specifier plus the overt complementizer in the head that needs to be adjacent to the verb in such environments.
Events and copulas
Authors: Escribano Gonzalo 
Published: June 2024

This paper focuses on the study of a particular phenomenon of variation related to the distribution of Spanish copulas: the (in)compatibility of event nouns with predication structures where the copula estar and an evaluative adjective are combined. Some structures, such as La boda estuvo preciosa (‘The wedding wasESTAR beautiful’) are present across all Spanish varieties, contrasting with examples such as La tormenta estuvo horrible (‘The storm wasESTAR horrible’), that are attested only in certain specific varieties, and that could be considered an instance of so-called innovative uses of estar. We give here a first picture of the extension of this phenomenon. Secondly, we develop the relevant distinction within the domain of event nouns that is needed to give an accurate explanation of the facts under examination. Finally, we show how these facts fit within the overall picture of copulative variation in Spanish, thus making a significant contribution to our broad understanding of Spanish copulas.

Como antecedente de este trabajo tenemos el daño al medio ambiente, causado por personas naturales y jurídicas que en su diario accionar realizan actividades contaminantes. La contaminación es diversa, puede ser del aire, del agua; el ruido intenso provoca también contaminación. En la Constitución de la República del Ecuador, en su artículo 14, se recoge el derecho al buen vivir que tenemos todos los ecuatorianos, sin distinción de ninguna raza, sexo, clase social o creencia religiosa; y, ese principio debe ser encaminado de forma correcta para cumplir con el buen vivir. El objetivo es tratar de evitar ese daño ambiental, a través de la concesión de incentivos de carácter tributario ambiental, que vuelvan atractivo el cuidado del medio ambiente y la remediación del daño causado. El tipo de investigación es cualitativa. Para esta investigación se utilizan los métodos teóricos: histórico–lógico, análisis-síntesis; el método inductivo-deductivo; y, el método empírico de análisis documental. Se identifica una limitada normativa tributario ambiental llegando a la conclusión de que es necesario proponer la creación de incentivos tributarios a través de reformas legales que permitan aplicar el principio constitucional de que la naturaleza es sujeto de derechos, principio que está recogido en la Carta Magna.

Published: June 2024

The safety of children near water is crucial to avoid drowning, a major cause of death among children worldwide. Drowning incidents are a significant issue in Malaysia, especially among young people. The greatest obstacle to the development of policy for water safety among school children is lack of awareness or knowledge of water safety. This study represents an attempt to measure attitudes towards waters safety and risk of drowning in the District of Gombak in Malaysia. Given the urgency of the matter, immediate attention and action are required. Therefore, this paper seeks to highlight the pressing nature of water safety concerns among school children and assess whether implementing a water safety education program can substantially enhance knowledge levels, thus reducing drowning incidents among children. Yet, drowning in Malaysia still doesn't get enough attention. The sample of the study was 502 school children from a school in the district in Selangor. Purposive sampling was selected. The major findings that emerged were as below: a) the respondents prefer to swim alone. b) They are less favor in of wearing life jackets. c) They prefer to swim without having adults around them. d) They are prone to swim without learning to swim. e) No association between students’ attitudes towards water safety and sex. The urgency of this research is to address water safety issues among school children.

Compartmental models have gained tremendous usage in various fields, including epidemiology, pharmacokinetics, and ecology, to describe the dynamics of a system consisting of interacting compartments one need to understand that the challenges in using compartmental models is solving the system of ordinary differential equations (ODEs) that govern the dynamics of the compartments. In this study, we propose the use of the Adam-Bashforth predictor method to solve compartmental models formed from COVID-19 data in Malaysia between a specified period and we showcased its promising results. The Adam-Bashforth predictor method is a widely used numerical method for solving ODEs. It uses previous solution values to calculate the next solution value, and the solutions is refined by using another fashion of the formula known as ABM correction formula. We improved the performance of the Adam-Bashforth predictor method by using the first four solutions of the fourth-order Runge-Kutta method, which is another popular numerical method for solving ODEs, using the compartmental models. Our results showed that the Adam-Bashforth predictor method enhanced with the fourth-order Runge-Kutta method for accuracy and computational efficiency was able to capture the trend in the COVID-19 dataset used. Generally, the Adam-Bashforth method was about 2.5 times faster than the fourth-order Runge-Kutta method while maintaining similar accuracy. So merging two of them will in no doubt provide a better accuracy in solving the epidemiological model, the Adam-Bashforth method showed significantly accuracy, particularly in the early stages of the outbreak. The Adam-Bashforth predictor method is a promising numerical method for solving compartmental models. It offers better accuracy and computational efficiency, can be particularly useful in scenarios where accurate and fast predictions of compartmental dynamics are crucial. The model will be of great importance to the Malaysian Government, the Ministry of Health, and other stakeholders in disease management for an immediate and timely response to disease outbreaks.
