Changes in pulmonary function after long-duration adventure racing in adolescent athletes

The present study investigated the acute effects of a mixed-modality, long-duration adventure race on pulmonary function in adolescent athletes. Twenty male adolescents aged 14 to 17 years volunteered to participate in a wilderness adventure race of 68.5-km. Expiratory function was evaluated before, immediately after, and 24 h after race completion. Measurements included forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and peak expiratory flow (PEF). Maximal inspiratory and expiratory mouth static pressures (MIP and MEP, respectively) were also measured using a portable hand-held mouth pressure meter across the same time points. The mean completion time of the race was 05:38 ± 00:20 hours. A significant post-race decrease in FVC was observed immediately after the race (-5.2%, p = 0.01). However, no significant changes were observed for FEV1, PEF and the FEV1/FVC and FEV1/PEF ratios. In addition, estimates of respiratory muscle strength (MIP and MEP) were unaffected by the race. The long-duration adventure race induced no marked reduction in expiratory pulmonary function and this response was associated with no apparent respiratory muscle fatigue. Therefore, the pulmonary system of trained adolescent athletes was sufficiently robust to sustain the mixed-modality, long-duration adventure race of ∽5-6 h.

FABULA WHEEL AND PLOT MOVEMENT: HOW THE MOTIVIC COMPLEX WORKS IN A.P. CHEKHOV

The article considers the plot-forming potential of the invariant Chekhov pattern, which involves paired characters - the doctor and the investigator. Using the example of several texts ("Perpetuum mobile", "On Official Duty", "Drama on the hunt", "Investigator", "Ward No. 6"), we can see how this template works in different genre contexts (romantic novel, Christmas story, detective story) and how these contexts intersect with each other. Common to consider situational template are the motives of feeling and the vicious circle, which charged a mixed modality and intersect with the motive of theatricality, which, in turn, is associated with professional reflection, combining the figures of doctor, investigator and writer. Special attention is paid to the story "Drama on the Hunt", which is updated as a metatext, in which - against the background of the doubling of the character system - an additional semantic dimension of hunting as a narrative strategy is formed. The final texts of the group under consideration can be considered the stories "On Official Duty" and "Ward No. 6", in which a sense of duty and professional guilt is comprehended through an updated motivational complex.

Changes in pulmonary function after long-duration adventure racing in adolescent athletes

Objective: The present study investigated the acute effects of a mixed-modality, long-duration adventure race on pulmonary function in adolescent athletes. Methods: Twenty male adolescents aged 14 to 17 years volunteered to participate in a simulated competitive wilderness adventure race of 68.5-km. Expiratory function was evaluated by spirometry with an Ergocard CPX Clinical system before, immediately after, and 24 h after race completion. Measurements included forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), forced expiratory flows at 25%, 50% and 75% of FVC (FEF25, FEF50, FEF75, respectively) and peak expiratory flow (PEF). Maximal inspiratory and expiratory mouth static pressures (MIP and MEP, respectively) were also measured using a portable hand-held mouth pressure meter across the same time points. Results: The mean completion time of the race was 05:38 ± 00:20 hours. A significant post-race decrease in FVC was observed immediately after the race (-5.2%, p < 0.05). However, no significant changes were observed for FEV1, PEF or the FEV1/FVC and FEV1/PEF ratios. The results also showed no significant modifications in the maximal expiratory flow-volume curves irrespectively of FVC percentages (FEF25, FEF50, FEF75). In addition, estimates of respiratory muscle strength (MIP and MEP) were unaffected by the race. Conclusion: The long-duration adventure race induced no substantial reduction in expiratory pulmonary function and this response was associated with no apparent respiratory muscle fatigue. Therefore, the pulmonary system of trained adolescent athletes was sufficiently robust to endure the mixed-modality, long-duration adventure race of ∼5-6 h.

Developing Learning Strategies Through a Multimodal Vocabulary Project

In this research project the benefits to students of creating and using spaced-repetition vocabulary flashcards based upon different modalities—audio, visual, written, and mixed—are investigated. The study, conducted over two semesters with a class of Media English students, required students to learn the course vocabulary in stages using each modality individually before finally creating mixed-modality flashcards. At the end of the project students wrote journals to reflect on what they had learned from utilizing the different modalities to remember vocabulary and their experiences of using the technology. Subsequent analysis of these journals provides insight into not only students’ attitudes towards mobile learning and using online vocabulary flashcards but also how students can become more critical in developing vocabulary learning strategies tailored to their needs 当研究では、学生が、オーディオ、ビジュアル、文章、混合など様々なモダリティー（手法）に基づいて、間隔反復語彙フラッシュカード作成及びそれを利用した勉強方法の効果について調査する。2学期にわたり実施した当研究では、メディア英語クラスの学生は、混合モダリティフラッシュカードを作成する前に、それぞれのモダリティを利用して段階的にコース語彙を学習する必要があった。プロジェクトの最終段階において、学生はテクノロジーを利用した語彙学習経験を通し、様々なモダリティを利用して学んだことを振り返り、記事にまとめた。学生の記事に対するその後の分析は、学生のモバイル学習及びオンライン語彙フラッシュカードの利用に対する勉強姿勢だけでなく、彼らのニーズに合う語彙学習方法をより慎重に見極め開発できるようになる事を示唆している。

Deep into that Darkness Peering . . . Stood There Wondering, Fearing

This chapter reviews the diagnosis and management of irregular sleep/wake rhythm disorder (ISWRD) and sundowning. ISWRD is characterized by lack of a clearly defined sleep/wake circadian rhythm with episodes of sleep and wake at varying times of the day or night, unrelated to a normal sleep/wake, day/night circadian rhythm Patients with neurodegenerative disorders are at increased risk for ISWRD. The diagnosis of ISWRD requires sleep log or actigraphy monitoring for at least 7 days. ISWRD is a common cause of institutionalization. Sundowning can further disrupt sleep and has been associated with more rapid progression of dementia. Mixed-modality treatment is used for the treatment of ISWRD and involves the integration of approaches to optimize entrainment to synchronizing factors and behavioral therapy.

Diagnóstico que permita detectar fortalezas y debilidades para ofrecer la modalidad mixta en el Instituto Tecnológico de Altamira

Currently our country has a coverage of 38.4%, leaving ten points below the average for Latin America and the Caribbean (UNESCO, 2018), that means that so far only a little more than a third of the social demand has been met or target population. With respect to the state of Tamaulipas, in 2017 it was below average, widening its coverage gap by 15.5 percentage points (ANUIES, 2018). One way to increase coverage is to use innovative educational processes (Mortis Lozoya, Del Hierro Parra, García López, & Manig Valenzuela, 2015). The objectives of this work are: Make a diagnosis to detect strengths and weaknesses to offer the mixed modality at the Technological Institute of Altamira. For this, a survey will be carried out on the actors involved in this process, the students, the teachers, and the authorities.
