In the contemporary higher education landscape, the fusion of information literacy education and seamless integration of digital resources is imperative for fostering students' academic success amidst a surge in information flow and technological progression. Educational institutions, including the San Pedro College of Business Administration (SPCBA) in the Philippines, strive to synchronize with the evolving demands of the 21st century by prioritizing the roles of information literacy instruction and digital resource integration in shaping students' academic trajectories. This study aimed to elucidate the intricate relationship between information literacy instruction, digital resource integration, and academic success at SPCBA. Data collected from 180 college students through survey questionnaires revealed a high level effectiveness of information literacy, robust digital resource integration, and significant academic success. Correlation analyses uncovered moderate associations between information literacy instruction and digital resource integration, as well as between information literacy instruction and academic success. Additionally, digital resource integration exhibited a significant correlation with academic success. Regression analysis further highlighted that information literacy instruction significantly predicts academic success, especially when combined with digital resource integration. In light of these findings, recommendations were proposed to enhance information literacy programs, integrate digital resources into curricula, foster collaboration between faculty and librarians, and conduct regular assessments for improvement. This study contributes to the literature on information literacy, digital resource integration, and academic success, providing insights for optimizing student learning outcomes in the digital age. Further research is encouraged to explore the nuanced dynamics of this relationship and develop targeted interventions for educational enhancement.

Academic procrastination is a common challenge. High school is a critical period where students are introduced to more complex and demanding academic tasks. The transition from middle school to high school may bring about increased academic pressure, and students may struggle to manage their time effectively (Belmonte, 2019). Cramming behavior, often a direct consequence of procrastination, is a phenomenon that has become ingrained in academic culture, their efficacy in promoting long-term retention and understanding in the long run (Chew, 2021). People have diverse learning styles, and understanding these styles can enhance the effectiveness of education and training. One popular framework categorizes learners into four models which include the VARK model (Visual, Auditory, Reading/Writing, Kinesthetic), which adds a dimension for those who prefer reading and writing as their primary mode of learning. The goal of this study was to explore academic procrastination, cramming behavior and learning style of Grade 7 students of Pacita Complex National High School , to probe the relationship between academic procrastination and cramming behavior, academic procrastination and learning style, cramming behavior and learning and examined the predictive ability of academic procrastination and cramming behavior, taken singly or in combination, of respondents’ learning style of Grade 7 students of Pacita Complex National High School. The findings revealed that the over-all weighted mean of 2.39 revealed that the respondents do not procrastinate in terms of academics. On the other hand, an over-all weighted mean of 2.47. Furthermore, the study revealed that the respondents have “less manifested” cramming behavior. In addition, the learning style of the students was Kinesthetic with a total score of 670. Moreover, academic procrastination was not significant to cramming behavior with a p-values .128, .133 and .296 respectively, as well as academic procrastination and learning style was also not significant to learning style with a p-values of .894, .222, .336 and .670 respectively. Also, cramming behavior was not significant to learning style with of .733, .322 and .053 It implied that these predictors were not highly contributors to students learning style. This study is believed to be a beneficial reference to educators, school administrators and students.

Participating in sports is essential for young people's life skills development. Adults are engaged in sports in the same ways that young people are—to maintain good health, enhance their interactions with others, and enhance their abilities (Cihan and Ilgar, 2019). Sports help young people develop their physical talents, and everyone who frequently participates in a sport appreciates the value of fitness and training in terms of how well they perform. This study's objective was to look into the level of sports commitment, training motivation, and athletic performance, probe the relationship between the athletes' level of sports commitment, training motivation, sports commitment, and athletic performance, and level of training motivation and athletic performance, and examine the predictive ability of the level of sports commitment, and training motivation, taken singly or in combination, of the level of athletic performance of NCAA players in the University of Perpetual Help System, Laguna. The findings revealed that the Athletes’ level of sports commitment along with personal goals, coach impact, and time and effort was “very high”, while the respondents’ level of sports commitment along with intrinsic and extrinsic was “very high”. On the other hand, the respondents’ level of athletic performance along with self-confidence, athletic ability, and, emotional ability was “very high”. In addition, the athlete’s level of sports commitment in terms of time and effort, was significant to the level of training motivation in terms of intrinsic, respectively. In terms of respondents’ level of sports commitment in terms of coach impact was correlated to their level of athletic performance in terms of self-confidence, athletic ability, and emotional ability. It implied that these indicators had a substantial impact on athletes' performance. It is expected that this study could help establish and maintain a commitment to sports and motivation to achieve a high level of athletic performance.

Oralidad y ritual matrimonial entre los amuzgos de Oaxaca é a publicação póstuma da tese de doutorado em antropologia de Víctor Manuel Franco Pellotier. Formado em antropologia e linguística, Pellotier dedicou quase 20 anos de pesquisa entre os amuzgos dos estados mexicanos de Oaxaca e Guerrero, mas sua morte prematura em 2004, aos 50 anos, não lhe permitiu defender sua tese. Desde 1976 ele atuou como pesquisador e docente no Centro de Investigaciones y Estudios Superiores en Antropologia Social (CIESAS), tendo também trabalhado na Escuela Nacional de Antropología e Historia (ENAH) e na Dirección General de Educación Indígena (DGEI) do México. Seu trabalho prévio com a língua hñahñu, no Vale do Mezquital (estado de Hidalgo), contribuiu para a criação da Academia de la Lengua Hñahñu, e suas pesquisas entre os amuzgos possibilitaram a documentação e o fortalecimento de sua língua.

This study aimed to produce and characterize a novel material from fish scales and chitosan for use as a medium for the extended release of herbicides. The mechanism of release for the herbicides atrazine and diuron was influenced by diffusion and swelling according to the power law kinetic model. The atrazine release time was seven days, while that of diuron was four days. The results of this study will contribute to the development of environmental matrices for herbicide release systems.

View angle and directional effects significantly affect reflectance and vegetation indices, especially when daily images collected by large field-of-view (FOV) sensors like the Moderate Resolution Imaging Spectroradiometer (MODIS) are used. In this study, the PROSAIL radiative transfer model was chosen to evaluate the impact of the geometry of data acquisition on soybean reflectance and two vegetation indices (Normalized Difference Vegetation Index - NDVI and Enhanced Vegetation Index -EVI) by varying biochemical and biophysical parameters of the crop. Input values for PROSAIL simulation were based on the literature and were adjusted by the comparison between simulated and real satellite soybean spectra acquired by the MODIS/Terra and hyperspectral Hyperion/Earth Observing-One (EO-1). Results showed that the influence of the view angle and view direction on reflectance was stronger with decreasing leaf area index (LAI) and chlorophyll concentration. Because of the greater dependence on the near-infrared reflectance, the EVI was much more sensitive to viewing geometry than NDVI presenting larger values in the backscattering direction. The contrary was observed for NDVI in the forward scattering direction. In relation to the LAI, NDVI was much more isotropic for closed soybean canopies than for incomplete canopies and a contrary behavior was verified for EVI.Os efeitos direcionais e de ângulo de visada afetam significativamente a reflectância e os índices de vegetação, especialmente quando são usadas imagens diárias adquiridas por sensores com amplo campo de visada como o Moderate Resolution Imaging Spectroradiometer (MODIS). No presente estudo, o modelo de transferência radiativa PROSAIL foi escolhido para avaliar o impacto da geometria de aquisição de dados na reflectância da soja e no cálculo de dois índices de vegetação (Normalized Difference Vegetation Index -NDVI e Enhanced Vegetation Index -EVI), variando-se parâmetros bioquímicos e biofísicos do dossel. Os valores usados para a simulação PROSAIL foram definidos com base na literatura e foram ajustados pela comparação entre espectros de soja simulados e adquiridos pelos sensores MODIS/Terra e hiperespectral Hyperion/Earth Observing-One (EO-1). Os resultados mostraram que os efeitos direcionais e de ângulo de visada na reflectância foram mais fortes com a diminuição do índice de área foliar (IAF) e da concentração de clorofila. Por ser mais dependente da banda do infravermelho próximo (IVP), o EVI foi muito mais sensível à geometria de visada do que o NDVI, apresentando maiores valores na direção do retroespalhamento. O contrário foi observado para o NDVI na direção do espalhamento frontal. Em relação ao IAF, o NDVI foi mais isotrópico para dosséis fechados de soja do que para dosséis esparsos, e um comportamento contrário foi verificado para o EVI.

Insecticidal activity of essential oils of Pelargonium graveolens, Lippia alba and compounds geraniol, linalool, 1,8-cineole, limonene, carvone, citral and Azamax® were evaluated against Spodoptera frugiperda. Topical application assay showed essential oil of P. graveolens has acute toxicity against Spodoptera frugiperda larvae (third instar) with LD50 1.13 µg/mg per insect and LD90 2.56 µg/mg per insect. Three essential oils of L. alba also exhibited insecticidal activity with LD50 ranging from 1.20 to 1.56 µg/mg per insect and LD90 from 2.60 to 3.75 µg/mg per insect. Geraniol, linalool, carvone and citral caused significant mortality of 30, 90, 84 and 64% respectively, compared to negative control. The bioinsecticide, Azamax®, caused lower mortality than the compounds of the essential oils.

Jugular vein puncture was done to collect blood before, during and after rides. Data were analyzed using a mathematic approach, based on the hematocrit and blood volume where the percentual change in plasma volume was used to correct the values of each variable analyzed. Significance was inferred when P

A humanidade sempre utilizou a biomassa para fins energéticos, porém com o aumento da demanda, ameaças à segurança energética e os danos para o ambiente e para a saúde decorrentes da utilização dos combustíveis fósseis, a importância desta fonte renovável vem sendo resgatada. Neste cenário, o planejamento agroenergético passa a ser de grande importância para países tropicais como o Brasil, pois permite viabilizar a produção de biomassa para energia onde esta é requerida, de forma sustentável, sem deixar de considerar os aspectos sociais e ambientais. Desta forma, o presente artigo tem por objetivo apresentar importantes questões relacionadas ao planejamento energético regional, como forma de contribuir para soluções e políticas públicas relacionadas à produção de energia de biomassa. Ademais, é apresentada a contribuição das técnicas de Sensoriamento Remoto e Sistemas de Informações Geográficas para avaliações de áreas potenciais ao cultivo de culturas bioenergéticas, além de um modelo conceitual que demonstra como essas técnicas podem constituir-se em ferramentas de apoio à tomada de decisão estratégica nesta área de bioenergia. Adicionalmente, algumas dificuldades e limitações para o planejamento territorial e agroenergético também foram relacionadas.Since early times, the human kind has been using the biomass for energy purposes. However, the current increasing energy demand can endanger the energy security of the nations and, as well, could put in risk the planet's environmental quality and human health. Thus, by the issues concern about the fossil fuels utilization, the importance of renewable energy sources is being rescued. In this scenario, the biomass energy planning becomes very important to tropical countries, like Brazil, because it would allow stimulating the production of biomass for energy where it is required, but in a sustainable way, considering the social and environmental aspects. Thus, this study aims to present important aspects related with regional energy planning as a contribution for proposing better solutions to energy demands and to think about better public policies related to energy production from biomass. Besides, a contribution of Remote Sensing and Geographic Information System in order to assess areas for biomass energy production and a conceptual model are presented as framework which demonstrates how these techniques can constitute support tools to strategic decision making process in bioenergy issues. Some difficult and constraints to territorial and agro-energy planning in Brazil was also presented.

The aim of this work was to determine the dioctyl azelate (DOZ) plasticizer diffusion coefficient (D) for samples containing the interfaces of rubber, liner and solid composite propellant based on hydroxyl-terminated polybutadiene (HTPB). The samples used in the diffusion study were aged up to 31 days after the cure period at 80 °C. A computer program implementing a mathematical model of Fick's second Law of diffusion was developed to calculate the diffusion coefficient based on concentration data obtained from gas chromatographic analyses. The effects of the diffusion phenomenon were also investigated by Shore A hardness and scanning electron microscope (SEM) techniques. These analyses were carried out using samples aged at room temperature and at 80 °C. The hardness results showed an increasing trend for the samples aged at room temperature; however in the tests carried out at 80 °C they showed the opposite trend. The SEM analyses detected meaningful changes in the surface morphology of the propellant for both aging temperatures.

This study analyzes the structure and floristic composition of the regeneration of native forest species under black-wattle plantation, established 16 years ago in a riparian area, and it verifies the possibility of the black-wattle be considered an invasive species of this environment. The tree stratum (circumference at breast height (CBH) ≥15 cm) was evaluated in 12 plots of 100 m2, established in four blocks. The natural regeneration stratum (0.3 m height to Casearia sylvestris, Myrsine lorentziana and Zanthoxylum petiolare presented the larger importance value in the tree stratum and Faramea marginata, Myrsine lorentziana and Myrcia glabra the biggest density in the natural regeneration stratum. The ecological characteristics of the species found in several height strata indicated that the forest succession process is in evolution. The black-wattle did not regenerate in this area and the planted trees of this species are in the senescence phase. Only 100 tree/ha of black-wattle were found, which represents 4.5% of the original population. Thus, black-wattle is not an invasive species for this environment.

O objetivo deste trabalho foi caracterizar a arquitetura do sistema radicular de árvores de acácia-negra (Acacia mearnsii) aos três anos após o plantio, em razão da combinação de oito tipos de recipientes e seis misturas de substratos usados na produção das mudas, levando-se em consideração atributos químicos e físicos do solo. As árvores foram plantadas no município de Cristal (RS), em solo Podzólico Vermelho Escuro, que apresentou alta densidade, baixo pH e excesso de alumínio. O tratamento que teve maior desenvolvimento radicular foi o fertil-pot, com substrato constituído por solo adubado, que diferiu estatisticamente dos tratamentos tubete redondo, com solo adubado + casca de acácia esgotada + vermiculita; paper pot, com solo adubado e laminado acondicionado em caixas de madeira, com solo adubado. O desenvolvimento e arquitetura das raízes no campo foram afetado pelo recipiente, mas não pelo substrato utilizado na fase de viveiro.The objective of this study was to characterize the architecture of the root system of black wattle trees (Acacia mearnsii), three years after planting, in relation to eight types of containers and six substrata used in the nursery, considering chemical and physical conditions of the soil. The experiment was carried out in Cristal (RS), in a Podzolic Dark Red soil. The soil presented high density, low pH and excess of aluminum. The treatment that induced larger root development was fertil-pot with fertilized soil, which differed significantly from the treatments round plug, with fertilized soil + acacia exhausted bark + vermiculite; paper pot, with fertilized soil and laminated in wood box, with fertilized soil. The development and the architecture of the roots in the field was affected by the container but not by the substrata used in the nursery.

Utilizando-se como padrão as medidas lisimétricas de um gramado, avaliaram-se os resultados de estimativas de ETo obtidas com Dar_méd oriundos de 14 métodos para seu cálculo. Tais comparações permitiram separar os métodos de cálculo de Dar_méd em três grupos, ou seja: um grupo resultou sempre em superestimativa de ETo; em outro, a tendência foi de sempre subestimar, e no último a tendência foi de superestimar valores baixos (< 4,5 mm dia-1) e de subestimar valores altos de ETo. Não foram observadas diferenças significativas (teste t; p < 0,05) de ETo, em função dos métodos de Dar_méd ao utilizar a média horária da temperatura e/ou umidade relativa do ar em relação aos determinados com a média dos valores máximo e mínimo desses elementos. Dos métodos propostos pelo boletim FAO56, apenas o que utilizou a umidade relativa média para calcular a pressão parcial de vapor d'água (e a) apresentou estimativa satisfatória. As melhores estimativas de ETo foram obtidas com os métodos de Dar_méd, que utilizaram média da temperatura do ar na determinação da pressão de saturação (e s), e média da umidade relativa para ea. A utilização do déficit de pressão de saturação em um único horário (9 e 10 h local), como representativo para o Dar_méd, mostrou-se boa alternativa na estimativa da ETo, para as condições climáticas de Piracicaba - SP.The results of the evapotranspiration obtained with the Dair_avg proceeding from 14 methods were evaluated, by using the lysimetric measures of a sward. These comparisons allowed to separate the Dar_avg calculating methods into three groups: a group always resulted into an overestimate ETo; in other one always tended to underestimating the ETo; and in the last tended to overestimating the low values (

Surgical Eye-camps for cataract treatment of low-income adult Mexicans have been undertaken over the last 10 years. Despite the high prevalence of cataracts among these subjects, no assessment of their nutritional or health status has ever been made. We compare the results obtained for 81 adults (44 men and 37 women) who received treatment in May 1997 with those for a "control" group of age and sex-matched but affluent individuals in Mexico City. a-Tocopherol and b-carotene were assessed and analysed by HPLC and colorimetric procedures, respectively. The plasma tocopherol to cholesterol ratio did not reveal deficiencies of this vitamin, and only 5 patients (2 men and 3 women) had low b-carotene plasma levels. The patients had high BMI values, with 32% of men and 30% of women overweight, and 2% and 14%, respectively, obese, with higher glucose, cholesterol and triglyceride values reflecting enhanced insulin resistance and lipid abnormalities. The alkaline phosphatase values were elevated ,suggesting that many of these blind patients are osteomalacic because they now remain indoors. Although it has been suggested that an adequate intake of carotenes and tocopherol are associated with absence of cataract, this appears not to be the case in our study population. Surveys in Mexico have revealed, however, a highly prevalent deficiency of other vitamins such as niacin and riboflavin, both of which have been proved to be protective against cataract. It appears that nutritional deficiencies, obesity, incipient diabetes and lipid disorders co-exist in modern Mexico. We have identified a need for research to aid the design of preventive nutritional approaches at the population level that could be applied in parallel with ongoing surgical treatmentNutrición y catarata en mexicanos de bajo ingreso: experiencia en un campamento de cirugía de ojos. Durante los últimos 10 años se han llevado a cabo en México Campamentos Quirúrgicos para el tratamiento de catarata en sujetos de escasos recursos. A pesar de la alta prevalencia de catarata, nunca se ha valorado el estado de nutrición ni de salud de éstas poblaciones. En este estudio comparamos los resultados obtenidos en 81 adultos (44 hombres y 37 mujeres) que recibieron tratamiento en Mayo de 1977, con los de un grupo "control" de sujetos de mayor afluencia, pareados para edad y sexo. Se valoraron los niveles de a-tocoferol y b-carotenos los cuales se analizaron con HPLC y colorimetría respectivamente. La relación tocoferol:colesterol en plasma no reveló deficiencia de ésta vitamina, y se encontraron niveles plasmáticos bajos de b-carotenos en solo 5 sujetos (2 hombres y 3 mujeres). Los IMC se encontraron elevados: 32% de hombres y 30% de las mujeres con sobrepeso y 2% y 14% obesos respectivamente. Los valores de glucosa, colesterol y triglicéridos fueron altos lo que refleja un aumento en la resistencia a la insulina y anormalidades en los lípidos. Los valores de fosfatasa alcalina se encontraron elevados lo que sugiere que muchos de estos pacientes ciegos padecen osteomalacia ya que permanecen confinados a su hogar. Aunque se ha sugerido que una ingesta adecuada de carotenos y tocoferol están asociadas a ausencia de catarata, ese no fue el caso en la población estudiada. Estudios en el país revelan, sin embargo, la deficiencia altamente prevalente de otras vitaminas tales como la niacina y la riboflavina cuyos efectos protectores en catarata han sido comprobados. En el México moderno por lo tanto, coexisten las deficiencias nutricias, la obesidad, la diabetes incipiente y las alteraciones en los lípidos. Hemos identificado la necesidad de que se inicien investigaciones que apoyen programas preventivos de nutrición a nivel poblacional que pudieran ser implementados paralelamente al tratamiento quirúrgico

Chagas' disease remains a major public health concern throughout much of Latin America. In Brazil, segments of the population experience Trypanosoma cruzi infection rates as high as 65%, indicating that control programs are still needed. Few data are available concerning people's health beliefs related to Chagas' disease in heavily infected populations. Such health beliefs may significantly impact the effectiveness of intervention schemes. The purpose of this study was to assess health beliefs related to Chagas' disease in a population experiencing high infection rates with the causal parasite. The focal population for the study consisted of the residents of Posse, a rural community in the State of Goiás. The results indicate that a majority of the population had a high degree of knowledge about Chagas' disease and the vector involved in its transmission. These findings indicate that control programs conducted by the Brazilian Ministry of Health have included effective educational components.A doença de Chagas persiste como importante problema de saúde pública em grande parte da América Latina. No Brasil, vários segmentos da população apresentam taxas de infecção pelo Trypanosoma cruzi que chegam até 65%, sugerindo que os programas de controle ainda são necessários. Há poucos dados disponíveis sobre as crenças populares relativas à doença de Chagas entre comunidades com altas taxas de infecção. Tais crenças podem ter um impacto significativo sobre a eficácia das intervenções. O objetivo deste estudo é avaliar as crenças relativas à doença de Chagas numa população com altas taxas de infecção pelo agente etiológico da doença. A população-alvo do estudo foi composta de moradores da Posse, uma comunidade rural no Estado de Goiás. Os resultados indicam que a maioria da população tinha um alto grau de conhecimento quanto à doença de Chagas e seu vetor. Os achados apontam para a eficácia dos componentes educativos dos programas de controle implementados pelo Ministério da Saúde.

Este estudo mostra a vantagem econômica da distribuição descentralizada de álcool etílico, diretamente a partir das usinas produtoras, contra a política usualmente utilizada de distribuição de vários produtos (álcool, gasolina e óleo diesel) com o intermédio de bases de distribuição. A análise de investimentos utilizou um modelo de distribuição baseado em programação linear para avaliar os custos logísticos. Os resultados quantitativos do estudo influenciaram o cliente do estudo (um dos produtores de álcool) a iniciar esforços para que o governo brasileiro alterasse as regulamentações restritivas, o que foi feito em julho de 1993.This study affirms the economic advantage of decentralized distribution of ethanol fuel, directly from the producing mills, as compared to the federally mandated practice of centralized, multi-product (ethanol plus fossil fuels) distribution. The investiment analysis employed logistics costs evaluated with a transshipment (LP) model. The quantitative results from the study influenced the client organization to begin lobbying efforts to change associated federal regulations, which was approved by CNP in July 1993.

Os autores fazem um breve relato da evolução histórica da leishmaniose visceral no Estado do Maranhão, Brasil, avaliando as possíveis causas da expansão da referida doença no Estado, assim como as medidas de controle adotadas pelo Ministério da Saúde objetivando a diminuição da incidência da mesma.The authors provide a brief report on the historical evolution of visceral leishmaniasis in the State of Maranhão, Brazil, evaluating possible factors for growth of the disease in the State and control measures by the Brazilian Ministry of Health to integrate health services finto the maintenance of control programs.

the present interview is about the preservation and the compositional process of Convivium (1986), by the composer Harry Crowl. The piece was composed on magnetic tape, which is a factor that makes its preservation difficult. The composer reveals aspects of the process of preserving a musical work as an individual, taking into account the relations between the compositional process, the socio-political context in which it was created and the media that was used to record it. Based on these relations, it becomes possible to digitize the original piece on an updated media in order to preserve it. In addition, the interview deals in some details about the working conditions of most composers of electroacoustic music in Brazil in the 1980s, therefore this interview has a musicological relevance.

The first application of laparoscopic liver surgery consisted of wedge liver biopsies or resection of peripheral lesions, mostly benign. More recently, reports of anatomic left and right hepatectomy have been seen in the literature. Expertise in some centers has evolved to such an extent that even living related donor hepatectomy has been performed. The aim of this paper is to report a laparoscopic right hepatectomy and describe in detail the surgical technique employed. To our knowledge this is the first case performed in Brazil totally laparoscopically. The surgery followed four distinct phases: complete mobilization of the liver; hilum dissection with encircling of right portal vein and right hepatic artery, caval dissection using linear vascular stapler to divide right hepatic vein and parenchymal transection with harmonic shears and firings of linear staplers are used to divide segmental 5 and 8 branches of middle hepatic vein. The liver specimen was removed by Pfannenstiel incision. Intraoperative blood loss was estimated in 120 ml with no need for blood transfusion. Hospital stay was 5 days. Laparoscopic right hepatectomy is feasible, technically demanding but can be safely accomplished by surgeons who have experience in advanced laparoscopic procedures and open hepatic surgery. In Brazil laparoscopic liver surgery is still in its first years and there is a lack of technical description of this complex procedure.
