Despite numerous studies focusing on the association between online learning interaction and satisfaction, few studies has investigated the relationship between learners’ perceived interaction and continuance intention. Although it has been found that learners’ age, gender, and prior experience could play a role in previous educational researches, further inquiries of demographic variables are still relatively rare in online learning studies. The primary purpose of this study was not only to investigate the key role of learners’ age, gender, and prior experience difference in online learning satisfaction and continuance intention but also to understand the effect of the perceived interaction on learners’ continuance intention. 122 online learning students from two universities in the southeastern United States participated in this study. An online survey was utilized to gather the data. The stepwise regression, one-way ANOVA, and Tukey’s Post Hoc Test were conducted to analyze the data. It was found that learners’ perceived usefulness, satisfaction, and learner-learner interaction had a positive effect on their continuance intention. Within four factors, the satisfaction appeared to have the most important influence on continuance intention. The results of one way ANOVA revealed that except for the prior-experience difference existing in the interaction between learners, no age, gender, or prior experience difference existed in the other online learning factors. The Tukey’s Post Hoc Test was performed to determine the differences between different prior-experience groups. It was demonstrated that the learners that had taken more than four online courses appeared to have a higher level of learner-learner interaction. In order to further enhance and maintain online learning effectiveness and efficiency, the institutions of higher education and online learning service providers should first focus on learners’ satisfaction with online learning programs. Moreover, learners’ perceived usefulness appears to have the second influential power toward their continuance intention. The continuous maintenance and upgrade in online learning technology would be one of the key components that could affect learners’ continuous participation in future online learning programs. Finally, the learner-learner interaction appears to have the least power toward online learners’ continuance intention. Nevertheless, the Tukey’s Post Hoc Test, revealing that the prior experience difference exists in learner-learner interaction, further suggests that learners with more online learning experience are very likely to have more interaction with online classmates than those with less online learning experience.

The aim of this in vitro study was to investigate the degree of C=C double bond conversion of high-viscosity dimethacrylate- or ormocer-based bulk-fill composites as a function of measurement depth. Four bulk-fill composites (Tetric EvoCeram Bulk Fill, x-tra fil, SonicFill, and Bulk Ormocer) and the conventional nanohybrid composite Tetric EvoCeram were applied in standardized Class II cavities (n = 6 per group) and photoactivated for 20 s at 1350 mW/cm2. The degree of conversion of the composites was assessed using Fourier-transform infrared spectroscopy at seven measurement depths (0.15, 1, 2, 3, 4, 5, 6 mm). Data were analyzed using repeated measures ANOVA and one-way ANOVA with Bonferroni post-hoc tests (α = 0.05). The investigated bulk-fill composites showed at least 80% of their maximum degree of conversion (80% DCmax) up to a measuring depth of at least 4 mm. Tetric EvoCeram Bulk Fill and Bulk Ormocer achieved more than 80% DCmax up to a measuring depth of 5 mm, x-tra fil up to 6 mm. The conventional nanohybrid composite Tetric EvoCeram achieved more than 80% DCmax up to 3 mm. In contrast to the conventional composite, the investigated ormocer- and dimethacrylate-based bulk-fill composites can be photo-polymerized in thick layers of up to at least 4 mm with regard to their degree of C=C double bond conversion.

A urbanização nas zonas costeiras torna necessário avaliar o impacto antrópico sobre os ecossistemas associados. O objetivo deste trabalho foi analisar temporalmente a dinâmica de populações de macroalgas com potencial bioindicador, estabelecendo-as como ferramenta para avaliação da saúde ambiental. Foi amostrado o ambiente recifal intertidal da Praia de Formosa, no Município de Cabedelo, Estado da Paraíba, Nordeste do Brasil, durante intervalos trimestrais de agosto/2013 a novembro/2014. A variação temporal da frequência de ocorrência (F') das populações macrofitobênticas foi avaliada pela análise de variância (One-Way Anova) com teste Post-Hoc de Tukey. A influência das variáveis ambientais sobre F’ foi avaliada pela Correlação Linear de Pearson e pela PERMANOVA. A análise da qualidade ambiental e a proposta de biomonitoramento basearam-se no Grupo 1, formado por espécies perenes e/ou raras com maiores valores ao longo do Componente Principal 1 (CP1) da Análise de Componentes Principais (ACP), e Grupo 2, formado por espécies com comportamento errático com menores valores ao longo do CP1 da ACP. Foram encontradas 33 espécies macrofitobênticas. A frequência de ocorrência apresentou variação temporal, porém não influenciada pelo conjunto de variáveis ambientais. Phyllodictyon anastomosans, Gelidiella acerosa e Gelidium corneum compuseram o Grupo 1, com Dictyopteris delicatula, Canistrocarpus cervicornis e Hypnea spinella formando o Grupo 2. O Grupo 2 apresentou correlação positiva com a temperatura, alcançando as máximas frequências nos períodos mais quentes, mas esse fator isolado não é capaz de explicar a distribuição errática das espécies. A ocorrência de espécies bioindicadoras de eutrofização foi considerada natural, fato que, aliado à alta frequência de espécies bioindicadoras de qualidade ambiental, sugerem que o Recife de Formosa não sofre impactos antrópicos significativos. O desaparecimento de espécies perenes ou crescimento populacional significativo de espécie rara (Grupo 1), bem como a fuga do padrão temporal de frequência ou dominância do recife pelas espécies do Grupo 2, são indícios da ocorrência de impactos. Este trabalho fornece à gestão do Recife de Formosa uma eficiente ferramenta para avaliação do impacto urbano sobre a comunidade macrofitobêntica.

Summary The variables impacting the efficiency of the offensive phase of the game in ice hockey may be determining factor for both the training process and game strategies. The research aimed to acquire and expand the knowledge about selected goal-scoring characteristics in the National Hockey League. A total of 511 even-strength goals were recorded in 129 randomly selected games in a regular-season 2020/2021 by indirect observation. Goals were differentiated by selected variable dimensions: location of the offensive team’s puck possession gain before scoring a goal, game situation preceding a goal, and the number of passes of the offensive team preceding a goal. Data were analyzed by performing a one–way ANOVA. Post hoc multiple comparisons were performed using the Tukey HSD test. The significance level of p ≤ 0.05 was used. Significant differences were found within all variable dimensions (p= 0.00001). In terms of the puck possession gain location, zone 1 (along the boards in the offensive zone) was the zone with the significantly highest mean score (p= 0.00305). Offensive zone play was significantly the game situation preceding most of the goals (p= 0.00000). The interval of the passes that preceded most of the recorded goals was the interval of 1 – 2 passes (p= 0.00000). Acquired results point out the dominance of particular variables and may help coaches to determine the content of the training process and game strategies. Based on the assumption of the realization of similar research in different environments in terms of the quality and age category, if the analogy would be found between the results of the present study and the results of potential studies, we can state the trends applicable to youth training.

Purpose: The inconsistencies and variations of creatine kinase level due to modifiable and non-modifiable factors were the basis of this study. The aim was to find out the relationships between creatinine and creatine kinase in the blood of somatotypes.    Methods: The 122 males, aged 10 to 20 years, were classified according to their somatotypes. Somatotypes were measured by the ISAK method. By standard laboratory methods, creatinine and creatine kinase estimate. The IBM SPSS version 24 is used for calculation. One way ANOVA followed by post hoc tests was performed to compare the variables among the three groups (p<0.05).   Results: Creatinine level in the blood insignificantly deferred among the three somatotypes. The significant differences (p<0.05) were found in creatine kinase level in the blood and creatinine/creatine kinase ratio among the three dominant Somatotypes. Creatine Kinase was significantly higher in Ectomorphs (212 U/L) than Endomorphs. Ectomorphs and mesomorphs have crossed normal creatine kinase levels (35 -175 U/L). The creatinine/creatine kinase ratio was found highest in endomorphs and lowest in the ectomorphs and significantly differed in three Somatotypes.   Conclusion: Creatinine production remains the same, indicating production of Creatinine is independent of specific body types. A significant higher Creatine Kinase level in Ectomorphs over Endomorphs showed fat content was not associated with it. Significant differences in Creatinine / Creatine Kinase ratio among Somatotypes suggested its relevance between cellular and morphological relationships and might uses as biomarkers.

Background: The study was undertaken to evaluate the learning and memory effect of lipid lowering drugs atorvastatin and simvastatin in alprazolam induced amnesic mice.Methods: The study was carried out on albino mice, divided into 4 groups of 6 animals each (either sex, 3-4 months of age, weight 25-30g). Amnesia was induced by administering Alprazolam (2mg/kg for 14 days) in all 4 groups from 1st to 14th day. In addition, group 2, 3 and 4 received Piracetam (400mg/kg), Atorvastatin (5mg/kg) and Simvastatin (5mg/kg) from 8th to 14th day respectively. The learning and memory of the animals was assessed by employing Elevated plus maze (EPM) and Step-down type passive avoidance (SDA) model.Results: Results were compared among the different groups using one way-ANOVA followed by post hoc Tukey’s test. The measured parameters were compared with standard drug Piracetam. In EPM model Atorvastatin (p<0.049) and Simvastatin (p<0.007) were comparable with standard drug Piracetam, whereas in SDA model only simvastatin group (p<0.001) showed significant result.Conclusions: In EPM model, both the statins showed significant improvement in learning and memory in alprazolam induced amnesic mice. However further studies are required to support these observations.
