 Hiện nay, điện thoại thông minh (ĐTTM) đang trở thành một thiết bị phổ biến của M – learning (hay Mobile learning – học tập bằng cách truy cập các nội dung dạy học thông qua thiết bị di động), nhất là trong bối cảnh các trường học buộc phải đóng cửa vì đại dịch. Nghiên cứu của chúng tôi nhằm xác định những yếu tố ảnh hưởng đến sự chấp nhận ĐTTM của 285 giáo viên toán tại các trường trung học ở tỉnh Bình Dương và Thành phố Hồ Chí Minh. Nghiên cứu sử dụng mô hình hồi quy tuyến tính đơn để phân tích ảnh hưởng của các biến giải thích lên sự chấp nhận ĐTTM như là công cụ dạy học. Kết quả cho thấy, sự tự tin khi sử dụng phần mềm dạy học (PMDH) toán, cảm nhận về sự khả thi của việc sử dụng PMDH toán và giới tính ảnh hưởng lên sự chấp nhận ĐTTM. Ngoài ra, kết quả kiểm định Chi – square cho thấy không có sự chênh lệch về mặt thống kê suy diễn giữa tổng thể các nhóm chấp nhận, phân vân và không chấp nhận ĐTTM trong dạy học toán mặc dù tỉ lệ mẫu của nhóm chấp nhận là lớn nhất.

AbstractObjectiveWe aimed to develop and evaluate a mobile learning (m-learning) design for large group application learning based on flipped classroom approach within an integrated curriculum of medical faculty.Materials and methodsTotally 359 students enrolled in a two-credit course during the 2017–2018 academic year. An instructional design called 5-Lecture-5 (5L5) was implemented via mobile application. This design is a blend of m-learning and flipped classroom approaches, with pre-, during-, and post-lecture elements. Data were analysed using Chi-square, Mann–Whitney U, and Kruskal–Wallis tests. Open-ended questions and course observations were analysed thematically and reported together.ResultsOf the participating students, 26.96% who saw the first announcement examined pre-lecture materials and 55.43% attended face-to-face lecture. Achievement test scores of those who attended lecture were significantly higher (p = 0.027). Correct response rates for each question were 99.30, 72.10, 58.70, and 94.40%, respectively. Consequently, students demonstrated positive attitude towards m-learning (M = 170.15 ± 28.48). The most preferred positive aspects were “active learning,” “interactive,” “entertaining,” “useful,” and “repeatable.”ConclusionsM-learning activities within a flipped classroom with instant feedback were found to increase participation and interaction levels of students in classroom setting, resulting in their increased enjoyment and engagement.

Purpose The aims of this study were to characterize hearing symptoms, habits, and sound pressure levels (SPLs) of personal audio system (PAS) used by young adults; estimate the risk of developing hearing loss and assess whether instructions given to users led to behavioral changes; and propose recommendations for PAS users. Method A cross-sectional study was performed in 50 subjects with normal hearing. Procedures included questionnaire and measurement of PAS SPLs (real ear and manikin) through the users' own headphones and devices while they listened to four songs. After 1 year, 30 subjects answered questions about their usage habits. For the statistical analysis, one-way analysis of variance, Tukey's post hoc test, Lin and Spearman coefficients, the chi-square test, and logistic regression were used. Results Most subjects listened to music every day, usually in noisy environments. Sixty percent of the subjects reported hearing symptoms after using a PAS. Substantial variability in the equivalent music listening level (Leq) was noted ( M = 84.7 dBA; min = 65.1 dBA, max = 97.5 dBA). A significant difference was found only in the 4-kHz band when comparing the real-ear and manikin techniques. Based on the Leq, 38% of the individuals exceeded the maximum daily time allowance. Comparison of the subjects according to the maximum allowed daily exposure time revealed a higher number of hearing complaints from people with greater exposure. After 1 year, 43% of the subjects reduced their usage time, and 70% reduced the volume. A volume not exceeding 80% was recommended, and at this volume, the maximum usage time should be 160 min. Conclusions The habit of listening to music at high intensities on a daily basis seems to cause hearing symptoms, even in individuals with normal hearing. The real-ear and manikin techniques produced similar results. Providing instructions on this topic combined with measuring PAS SPLs may be an appropriate strategy for raising the awareness of people who are at risk.

Abstract. Background: Research on young adults in the general population has identified a relationship between sexual minority identification and risk for suicide. Differential rates of suicidal ideation and attempts have also been found across racial and ethnic groups. Aims: This study examined risk for suicide among university students, based on membership in one or more marginalized groups (sexual minority and racial minority identification). Method: Data were collected from first-year college students (N = 4,345) at an urban university. Structural equation modeling was employed to model a suicidality construct, based on which a "risk for suicide" category system was derived. Chi-square and logistic regression analyses were then conducted to estimate the relationship between the background variables of interest and suicide risk. Results: Students who identified as lesbian, gay, or bisexual (LGB) were associated with higher suicide risk than their heterosexual peers. Students of color were slightly less at risk than their heterosexual peers. However, LGB students of color were associated with elevated suicide risk relative to heterosexual peers. Conclusion: Results indicate that belonging to multiple marginalized groups may increase one's risk for suicide, though these effects are not simply additive. Findings highlight the complexity of the intersection between marginalized identities and suicidality.

Introduction: The implementation of Therapeutic Patient Education (TPE) remains a challenge. An exploratory study highlighted two tendencies among practitioners of TPE, which could hamper this implementation: an oscillation between identities (as caregivers versus as educators) and an inclination towards subjective psychological health objectives. Objectives: To verify whether these tendencies can be observed among an informed audience in TPE. Next, to explore the variables associated with one or other of these tendencies. Method: A quantitative cross-sectional survey by a self-administered questionnaire was carried out among 90 French-speaking healthcare professionals. Statistical analyses (chi-square, logistic regression) were then conducted. Results: Sixty percent of respondents displayed identity oscillation, which was found to be linked to task oscillation, patient curability, scepticism towards medicine and practising in France. Fifty-six percent pursued subjective psychological health objectives, which was found to be associated with health behaviour objectives and a locus of power in the healthcare relationship distinct from those seen in the pre-existing health models (biomedical, global). This tendency seems to constitute an alternative model of TPE. Discussion & conclusion: Identity oscillation and subjective psychological health objectives can be both observed. This study stresses the need to deliberate on the form(s) of TPE that is/are desired.

High Grade Gliomas

SummaryA retrospective study was done to determine the incidence of and the risk factors predisposing to clinical venous thromboembolism (VTE) in patients treated for high grade gliomas. Medical records of 68 consecutive patients diagnosed and treated at Saint Francis Hospital and Medical Center from January 1986 to June 1991 were reviewed. The follow up was to time of death or at least 6 months (up to December 1991). All clinically suspected episodes of VTE were confirmed by objective tests. Sixteen episodes of VTE were detected in 13 patients for an overall episode rate of 23.5%. Administration of chemotherapy (p = 0.027, two tailed Fisher exact test) and presence of paresis (p = 0.031, two tailed Fisher exact test) were statistically significant risk factors for the development of VTE. Thrombotic events were more likely to occur in the paretic limb and this difference was statistically significant (p = 0.00049, chi square test, with Yates correction). No major bleeding complications were seen in the nine episodes treated with long term anticoagulation.We conclude that venous thromboembolic complications are frequently encountered in patients being treated for high grade gliomas and the presence of paresis and the administration of chemotherapy increases the risk of such complications.

Birds of the psittaciform order, composed by the Psittacidae and Loridae family have several characteristics making them more frequently kept as companion animals, promoting the increase of breeding sites in Brazil. The present study aimed to analyze the specificity and sensitivity of three different coproparasitological tests, Willis, Hoffman and Direto de feces, through statistical tests: Chi-Square and Kappa. 70 fecal samples of exotic parrots were collected from a commercial breeding site and these were submitted to the three tests, totaling 210 coproparasitological exams. Among the tests performed, 29,5% were positive for nematode eggs, cestodes and oocysts. Coproparasitological exams are inexpensive, have clinical importance, indicating the population of endoparasites and therapeutic treatments.

Introduction: Adolescent are at high risk of unwanted pragnency, including abortion, STIs, HIV/AIDS. Risky sexual behavior is one of the entrance transmissions of unwanted pregnancy. Such behavior can be influenced by various factors, beyond and within the individual factors. Teens need the support and motivation in deciding not to do risky sexual behavior. The purpose of this study was to investigate the determinants of adolescent behavior in the prevention of unwanted pregnancy.Methods: This research used cross-sectional design. The populations were students of senior high school in District Sintang. The were 123 respondents chosen by cluster sampling technique for this study. All data were collected using questionnaires and then analysed using bivariate (chi square) and multivariate analysis (logistic regression).Results: The results showed that the majority of respondents did not have good knowledge about the prevention of unwanted pregnancy. Related variable is the level of parental education (p=0.001), the support of parents/guardians (p=0.009), support teachers (p=0.005), peer support (p=0.039), residency (p=0.009), a pastime activity (p=0.000), knowledge of adolescents about reproductive health (p=0.016), perception ability of adolescents (p=0.006) and attitude of adolescents (p=0.049). Adolescent self-perception abilities are variables that most influence on the behavior of adolescents in the prevention of unwanted pregnancy.Conclusions: Efforts to improve reproductive health programs should be early and adolescent have responsibilities as well as healthy behaviors.
