Authors: Xia Yangyang , Zhang Wei 
Published: December 2024

With the increasing development of academic research, thesis writing and publication have become important ways to measure scientific research achievements. However, non-standard thesis formats not only affect the reading experience, but may also lead to a decrease in the evaluation of academic achievements. Therefore, this article proposes a rule engine based automatic paper format detection system, aiming to improve the efficiency and accuracy of thesis format review and reduce manual review costs. This system is built on the basis of the Office Open XML document specification, which formulates a series of format checking rules for the basic format requirements of thesis. Then, the rule engine conducts in-depth checks on the thesis based on the preset format specification, automatically identifies format problems that do not comply with the specification, and outputs a detection report. It provides modification suggestions to assist users in quickly correcting format errors.

Characteristics of Gerund, Participle I and Verbal noun
Authors: Babayev Javid 
Published: December 2024

The article elaborates some bullet points of gerund, participle I and verbal noun. The difference between verbal noun and gerund has been brought into notice with examples in the study. The article underlines that verbalization of the ing-form word is caused by adverbs mainly. It occurs when we add adverb after the ing-form word which makes the ing-form word transform into gerund. In this case, gerundized word cannot be pluralized. If the adverb is not added in the sentence, the ing-form word can be pluralized very easily. Furthermore, some obscure points about tense and voice of participle I and gerund have been clarified in the study. It turned out that gerund has the category of voice and the category of tense. Like gerund, participle I has both category of voice and tense. Moreover, the tense forms can be in present and present perfect.
ANÁLISE ALOMÉTRICA ENTRE FADIGA MENTAL E TRABALHO MECÂNICO
Authors: Tartaruga Marcus P. , Goebel Andreina Eloyse 
Published: December 2024

INTRODUÇÃO: A análise do desempenho tem despertado o interesse no que se refere a mecânica da locomoção humana, em especial, ao trabalho mecânico total (Wtot) - determinado pela soma dos trabalhos mecânicos interno (Wint) e externo (Wext) (ZAMPARO, e col. 2019). Na prática esportiva, estudos têm verificado a necessidade de utilizar valores diferentes como coeficientes para a determinação do percentual a ser considerado da massa corporal total no cálculo do Wtot. A escala alométrica é um exemplo. Ela é representada por uma equação de regressão que indica o comportamento de uma variável fisiológica “Y” em relação a variável massa “X” (Y = aXb) (TARTARUGA e col., 2013). Embora a literatura tenha demonstrado evidências científicas dos efeitos negativos da FM para com o desempenho cognitivo e esportivo, o comportamento do Wtot em corredores de longa-distância não tem sido investigado em tal situação de fadiga quando aplicada a alometria. Portanto o presente estudo teve como objetivo investigar, alometricamente, a relação entre fadiga mental (FM) e trabalho mecânico total (Wtot) de corredores recreacionais de longa-distância. MÉTODOS: A amostra foi constituída por quinze mulheres, com mais de dois anos de experiência em provas de 10 km. Todas as participantes foram submetidas a dois testes de Economia de Corrida realizados, randomicamente, sem e com fadiga mental (FM) induzida através de uma tarefa cognitiva de esforço (Stroop Task) de 30 min. Foi realizado o teste de Shapiro-Wilk para a verificação da normalidade dos dados, teste T de Students para amostras dependentes e o teste comparativo não paramétrico Wilcoxon. O índice de significância adotado foi de 0,05 no programa estatístico Statistical Package for the Social Sciences – SPSS (IBM, USA). RESULTADOS: Não foram verificadas diferenças estatisticamente significativas no Wtot, sem e com FM, apesar do efeito cognitivo significativo induzido pelo Stroop Task de 30 min. Alometricamente, os resultados do nosso estudo também não demonstraram alterações significativas quando comparado o Wtot com e sem FM. É provável que estes resultados estejam relacionados aos valores homogêneos verificados nos nossos parâmetros de massa corporal e VO2máx - próximos de 10%. Segundo Tartaruga e col. (2010), comportamentos homogêneos intersujeitos da massa corporal e do VO2máx resultam em elevados valores exponenciais alométricos (< 0,9) diminuindo, assim, o efeito de prováveis diferenças na potência metabólica máxima, o que justifica o uso deste procedimento para amostras heterogêneas. CONSIDERAÇÕES FINAIS: O presente estudo permite concluir que 30 min de esforço mental para induzir a FM parece não afetar significativamente as respostas fisiomecânicas de corredoras de 10 km, sugerindo-se uma possível estratégia de enfrentamento individual advinda da experiência esportiva.

Published: December 2024

INTRODUÇÃO: O processo de envelhecimento é marcado pela perda de massa muscular, alterações vestibulares, declínio do controle postural e outras mudanças sensoriais que prejudicam o equilíbrio corporal, aumentando os riscos de quedas. Além do envelhecimento, a obesidade também pode estar associada com alterações na função neuromuscular, na funcionalidade geral, no controle postural e no equilíbrio. OBJETIVO: Investigar o efeito da obesidade, através do índice de massa corporal-IMC, no equilíbrio estático e dinâmico de idosos. MÉTODOS:Trata-se de um estudo observacional, transversal, descritivo com amostra por conveniência, formada por participantes de um programa de extensão universitária. Critérios de elegibilidade foram: idade ≥ 60 anos, concordância com o TCLE (CEP/UFRGS 5.993.354), não utilizar órtese ou prótese de membros inferiores, não apresentar patologias prévias que comprometam o equilíbrio. Sessenta idosos foram divididos em 3 grupos de acordo com o IMC: eutróficos (G1; n=23; 68,9±8,1 anos), sobrepesos (G2; n=24; 67,4±5,9 anos) e obesos (G3; n=15; 71,2±9,5 anos). A avaliação incluiu antropometria (peso e altura para cálculo do IMC); valor médio entre 3 repetições de testes de equilíbrio estático: unipodal com olhos abertos e fechados por 30 segundos (EEOA/EEOF) e teste de equilíbrio dinâmico pelo teste Timed up Go (TUG). A análise estatística foi constituída de uma análise descritiva e comparativa entre grupos pelo teste ANOVA com Post Hoc-Tukey (p<0,05; JASP). RESULTADOS: Os resultados obtidos no EEOA foram G1 23,25±10,60, G2: 25,27±9,13s, G3: 15,89±12,0 s. Houve uma influência do IMC sobre o EEOA [F(2,59) p=0,026], ocorrendo uma diferença entre os grupos G2 e G3, mas não entre os demais grupos, com tamanho de efeito grande (d Cohen’s=0,899), mostrando que individuos obesos permaneceram menos tempo em apoio unipodal. Nos resultados do EEOF não houveram diferenças significativas entre os grupos (G1:6,38±5,07; G2:6,16±7,226, G3:3,36±3,24). Em relação ao equilíbrio dinâmico TUG evidenciaram que indivíduos com maior IMC executaram o teste em maior tempo (G1:5,88±1,14s; G2 6,34±1,89s e G3 7,77±2,23s) sendo observada diferença entre G1 e G3 (d Cohen’s=1,077) e também entre G2 e G3 (d Cohen’s=0,815). CONSIDERAÇÕES FINAIS: Nossos achados demonstram influência da obesidade sobre o equilíbrio estático e dinâmico de idosos, corroborando com outros estudos. É possível observar que idosos obesos conseguem permanecer em apoio único com olhos abertos, por menos tempo em relação ao sobrepeso. Do mesmo modo, os obesos despendem maior tempo para realizar o teste TUG, em relação aos eutróficos e sobrepesos. Deste modo, podemos afirmar que a obesidade influencia de forma negativa o desempenho de equilíbrio estático e dinâmico de idosos, fator que está associado a maior risco de quedas e declínio funcional.
ANÁLISE DO GASTO ENERGÉTICO DE VOLEIBOLISTAS RECREACIONAIS
Authors: Santos Caroline 
Published: December 2024

INTRODUÇÃO: A maioria dos estudos se baseiam em estimativas aproximadas, fundamentadas em equações matemáticas e em dados de atividades físicas similares, consequência de diversas variáveis intervenientes tais como o ambiente dinâmico, o ritmo de jogo, a estratégia tática e a duração da partida, dificultando a realização de coletas de dados individuais, principalmente quando consideradas as funções táticas desempenhadas em quadra. Assim sendo, o presente estudo teve como objetivo comparar o GE de nove voleibolistas recreacionais masculinos especialistas nas funções de central, ponteiro e oposto. MÉTODOS: A amostra foi constituída por 9 voleibolistas recreacionais masculinos (3 centrais - idade: 20 ± 4 anos; massa corporal: 67,4 ± 0,8 kg; estatura: 1,75 ± 9,1 m; consumo máximo de oxigênio, VO2máx: 58,3 ± 8,7 ml.kg-1.min; equivalente metabólico da tarefa, MET: 16,7 ± 2,5; 3 pontas - idade: 23 ± 2 anos; massa corporal: 73,8 ± 9,0 kg; estatura: 1,77 ± 4,0 m; VO2máx: 61,1 ± 3,8 ml.kg-1.min; MET: 17,5 ± 1,1; 3 opostos - idade: 23 ± 2 anos; massa corporal: 76,0 ± 4,6 kg; estatura: 1,77 ± 5,0 m; VO2máx: 63,0 ± 9,2 ml.kg-1.min; MET: 18,0 ± 2,6), com experiência mínima de dois anos de prática. Todos assinaram o Termo de Consentimento Livre e Esclarecido (TCLE), que foi aprovado pelo Comitê de Ética em Pesquisa (n° 6.274.624), estando isentos de tratamento farmacológico ou lesões osteoarticulares. RESULTADOS: O presente estudo teve como objetivo analisar o GE de voleibolistas recreacionais masculinos nas funções central, ponteiro e oposto, sendo verificada tendências de opostos e pontas apresentarem maiores valores de GE e DP do que centrais. CONSIDERAÇÕES FINAIS: Existe uma tendência de jogadores opostos e pontas apresentarem maiores gastos calóricos do que centrais, provavelmente em decorrência de diferenças fisiomecânicas resultantes das funções desempenhadas. Novas pesquisas são sugeridos com maiores números amostrais, além de estudos que venham a relacionar o DP com a distância percorrida em partidas profissionais.

This study investigates the relationship between urban road transportation and land use patterns in Gbagada Lagos state. Using a mixed-methods approach combining Geographic Information System (GIS) analysis, survey questionnaires, and regression modeling, this research examines how road network density, traffic volume, and transportation modes influence land use changes. The findings reveal significant correlations between road proximity, land value, and urban sprawl. Specifically, areas with high road density exhibit increased commercial and residential development, while areas with limited accessibility experience decreased land value and reduced development. Policy recommendations include optimizing transportation infrastructure, promoting mixed-use development, and implementing smart growth strategies to mitigate urban sprawl and enhance sustainable land use. In particular, certain transportation planning decisions tend to increase sprawl (dispersed, urban fringe, automobile-dependent development), while others support smart growth (more compact, infill, multimodal development). These development patterns have various economic, social, and environmental impacts. This report describes specific methods for evaluating these impacts in transport planning.

Published: December 2024

An experiment was conducted to evaluate the utilization of protein and non-protein nitrogen on the performance and carcass characteristics of Red Sokoto bucks (RSB) in Northern Nigeria. Twenty four (24) RSB approximately 5-6 months were used in a completely randomized design of four treatments replicated six times. Four different diets were formulated using two protein nitrogen (Cotton seed cake – CSC and ground nuts cake - GNC) and two non-protein nitrogen (Urea and Poultry litter - PL), mixed each with wheat offal (WO). The diets were designated as I (Urea/WO), II (PL/WO), III (CSC/WO) and IV (GNC/WO). Data were taken on growth performance and carcass characteristics. Data obtained were subjected to analysis of variance using SPSS 23.0 (2017) for windows. The results of growth performance showed that, daily supplement intake and total supplement intake were highly significantly (P<0.001), final live weight and total weight gain were significant (P<0.05) and daily weight gain was significantly (P<0.01) different among the treatments. However initial weight gains of the bucks and feed conversion ratio were not different among the dietary treatments. Result of carcass characteristics showed that, all the parameters measured were significantly (P<0.01 or P<0.001), except spleen which was not affected by the dietary treatments. It could be concluded that diet IV (CSC/WO) being the best diet in improving the growth of the bucks and with no concomitant effects on the carcass characteristics of the bucks be recommended for feeding goats at 189.61 g/day.
