A Correlation Analysis of Education for Sustainable Development in Pre and Post Covid Scenarios

Education for sustainable development (ESD) has become a focus of international education attention, for its multidisciplinary character and for the interest in caring for the environment due to their degradation and environmental impact. This study compared two tests, one was conducted before confinement on 325 participants with 3545 responses, and one in confinement on 350 participants with 3832 responses. Surveys were conducted using Google Forms, based on 11 questions with its items verified by ANOVA and Bonferroni. The COVID-19 lockdown significantly influenced the results of both tests. The results indicated increased awareness of the environment during confinement. At the educational level it was intended to take an initial test and a year later perform a second test to compare them. The first test was carried out online at school, and the second one was held a year later in confinement due to COVID-19. This unexpected circumstance became an opportunity to value and compare them in different circumstances. Surveys were conducted using Google Forms. The results indicated a more significant concern for sustainability. The conclusion has been that students behave more sensitively to sustainable development in confinement circumstances.

Forest Optimization based Test Case Generation for Multiple Paths with Metamorphic Relations

In general multiple paths are covered by multiple runs which is a time consuming task. Now a days, metaheuristic techniques are widely used for path coverage. In order to reduce the time, an efficient method is proposed based on Forest Optimization Algorithm (FOA) with Metamorphic Relations (MRs) that cover multiple paths at a time in one run unlike the traditional search based testing. In the proposed approach, initial test case is generated using FOA, the successive test cases are generated using MRs without undergoing several runs. The motive of using FOA is that the searching mechanism of this algorithm having resemblance with the branch / path coverage techniques of testing. To the best of our knowledge, FOA has not been implemented in software testing. The experimental results are compared with three existing work. The efficiency of simply FOA is also shown how it able to cover multiple paths. The results show that FOA with MRs is more efficient in terms of time consumption and number of paths covered.

Evaluation of a MOOC developed from educational principles based on behavioral theory

This study’s objective was to evaluate a MOOC constructed from educational principles based on behavioral theory. The evaluation included the analysis of the performance, retention, and perception of the students. This MOOC consisted of an initial test, three teaching units, a final test and an assessment of the students' perception. The mean grade in the initial test was 6.34 (sd=1.20), and in the last attempt of the final test it was 8.75 (sd=0.51). The difference between these values was statistically significant and the effect size was considered very large. The retention rate was 44%, and 75% of students rated the overall experience as “Very Good”. The evaluated MOOC was effective in teaching its learning objectives and student retention was much higher than the average reported in other studies.These results indicate the relevance of the educational principles used in the elaboration of the MOOC.

The Effect of Proprioceptive Training upon the Upper Limbs Strength on Posttraumatic Shoulder Recovery in Weightlifter Women

This paper aims to examine the effects of proprioceptive training upon upper limbs force in the case of female weightlifters. 10 weightlifters from CSS N. Rotaru in Constanța, Romania, took part in an experiment specially designed for this purpose. The experimental group was assigned a proprioceptive training programme of 15 minutes two times per week, for a period of 20 weeks. The tests administered for the assessment of their upper limbs force were push-ups, push-ups on the Bosu ball, and dynamometry testing. Data analysis shows that no significant differences between the experimental group and the control group are visible at the initial test (p> 0.05). In the final evaluation, however, the experimental group obtained better scores than the control group in all tests. These findings indicate that the proprioceptive programme proposed has lead to the enhancement of female weightlifters’ muscular force. In conclusion, the programme is an efficient training tool that can be integrated with the sportswomen’s exercise routine.

Analyzing Learning Obstacle with Didactical Design Research on Three Dimensional Distance Material

he purpose of this study was to analyze the barriers to learning three-dimensional distance material using Didactical Design Research (DDR). The subjects of this study were two groups of class 12. The instruments used in this study were pretest (initial test) and post test (final test) which consisted of a test of the respondent’s ability, interview sheets, and observation notes. The data obtained were analyzed using three DDR steps: (1) didactic situation analysis by recontextualizing, repersonalizing, and developing didactic designs which include PDA (Pedagogical Didactic Anticipation); (2) metapedadidactic analysis by applying PDA; and (3) retrospective analysis linking didactic and metapedadidactic situations. The results showed that the identified learning obstacles can be anticipated by using PDA. The application of the didactic learning design shows that this design can be an alternative to third-dimensional distance learning in grade 12 because it can minimize student learning barriers that have been identified previously.

Utilization of Cardiac Surveillance in Pediatric Blood Cancer Survivors Who Received Anthracycline-Based Therapy Differs By Age: A Claims-Based Analysis

Background: The Children's Oncology Group Long-Term Follow-up Guidelines recommend surveillance for late effects in pediatric cancer survivors based on therapeutic exposures. In particular, the Guidelines recommend an echocardiogram, or comparable imaging, every 2 to 5 years to evaluate cardiac function in survivors exposed to anthracycline chemotherapy. However, little is known about the real-world utilization of cardiac surveillance tests following the completion of cancer therapy. Objective: This study fills this gap by describing the proportion of anthracycline-treated survivors of pediatric cancer who received surveillance for cardiac function following the completion of their cancer therapy. Method : We developed an algorithm to identify a cohort of pediatric cancer survivors using the IBM MarketScan ® Commercial Claims and Encounters Database (a nationwide private insurance enrollment and claims database). The cohort for inclusion was enrollees who (1) received anthracycline for blood cancer (leukemia or lymphoma); (2) aged ≤21 years at cancer diagnosis; (3) completed all cancer therapy between 2009 and 2018; and (4) remained continuously insured for at least one year post-therapy. Outcomes assessed included the receipt of: (1) echocardiogram, (2) cardiac magnetic resonance imaging (MRI), (3) multiple gate acquisition (MUGA) scan, and (4) any of the aforementioned cardiac surveillance tests over the 5-year period after the completion of all cancer therapy. The Kaplan-Meier (K-M) method was used to estimate the cumulative incidence of an event post-therapy, where the event was defined as the initial healthcare claim for a cardiac surveillance test. Individuals were censored if they had not received a test by study termination or were lost to follow-up at any time during the 5 years post-therapy. Multivariate Cox proportional hazard models were estimated to identify the demographic and cancer-related factors strongly associated with the initial test receipt. Results : Among 1,914 eligible blood cancer survivors, 259 (13.5%) survivors received a hematopoietic stem cell transplantation (HSCT; Table 1). The K-M estimated probability of receiving a cardiac surveillance test by 5 years post-therapy was 61.0% (95% Confidence Interval [CI]: 57.2% to 64.7%), with the median time to the initial test being 2.6 years (95% CI: 2.2 to 3.1 years) from therapy completion. The vast majority of cardiac surveillance test users underwent an echocardiogram (n=850; versus only 10 who had a cardiac MRI, and 14 who had a MUGA scan) by the end of their follow-up period. The proportion of survivors who had an initial cardiac test increased over time but varied by age at cancer therapy completion and the receipt of HSCT. The K-M estimated probability of receiving an initial test by 5 years post-therapy was: 86.0% (95% CI: 77.3% to 91.6%) for children (ages ≤11 years), 85.0% (95% CI: 75.4% to 91.1%) for adolescents (ages 12-17 years), and 36.8% (95% CI: 32.6% to 41.0%) for young adults (ages 18-28 years; Figure 1). Multivariate Cox models showed that compared with children, adolescents were more likely to receive an initial cardiac test (Hazard Ratio [HR] = 1.3; 95% CI: 1.1 to 1.5), while young adults were less likely to receive a test (HR = 0.4; 95% CI: 0.3 to 0.5). In addition, survivors who received a HSCT were more likely than those who did not to complete an initial cardiac test (HR=1.8; 95% CI: 1.5 to 2.2). Conclusions: This nationwide, claims data-based study showed that a substantial proportion of anthracycline-exposed survivors of blood cancers had not completed a cardiac surveillance test within 5 years post-therapy. Within this high-risk population, young adults were significantly less likely to receive surveillance testing for the prevention and early detection of cardiac dysfunction. Figure 1 Figure 1.
