TEACHING BUSINESS ENGLISH ONLINE. ASSIGNMENT ACTIVITIES AND TESTS IN MOODLE

In many universities around the world, the current pandemic situation confined the academic process to online interactions alone, with no physical presence in a class, the ‘face-to-face’ classes being held by means of applications or programs that provide video conferences facilities. Besides these tools for live communication, most universities – among which ours, as well – have started to make extensive use of the e-learning Moodle platform. Especially designed for the distance learning form of education, the Moodle platform has previously been used in our university mostly by the teachers involved in the distance learning form, particularly for the purpose of providing the distance learning students with study materials and other resources of interest for the subject – through the resources uploaded on the pages of the discipline -, for communication – by means of forums and chat rooms -, and for enabling a few tests and assignments along the semester. Now, with everything going online, the vast range of facilities this application offers has come to be discovered by all academics involved in the instruction process. In both synchronous and asynchronous activities organised by means of the platform, the user will find useful a series of facilities offered by the platform. Among these, the current study will refer to several diverse possibilities of using the activities of Assignment and Test for the classes of English for Business, with a series of examples of exercises that were created by means of these Moodle tools. The regular file upload assignment in which the student were instructed what to prepare, compose or solve, and upload at the specific button has now, with experience, ‘grown’ obsolete, more interesting online text types of assignment being preferred, such as video or audio records, texts written directly online in the applications or others types following templates and using materials posted. As for the tests, besides the basic types – more straightforward and easy to create – such as: multiple choice drills, matching, true / false, short answers, or drag and drop, there will be exemplifications of the embedded answers (cloze) type, which requires audacity and willingness from the teacher to put in more effort to prepare and self-instruct on how to use and enter special codes in order to create complex exercises. Needs teach us and eventually the results prove indeed rewarding and worth the effort.

Effects of Post-Activation Potentiation (PAP) Warm-up on Vertical Jump Performance among Volleyball Players

This study aims to examine the effects of resistance versus complex exercise with the retention of post-activation potentiation (PAP) on vertical jump among volleyball players. A total of 30 volleyball players (mean age = 16.5 ± 1.106 years old) were recruited as participants of this study. The participants were requested to attend two different testing sessions, with two days between each session. Each session had a different exercise routine, namely, resistance and complex. A one-way repeated measure was used to analyse the performance of the vertical jump, while a pairwise comparison was applied to compare the retention of PAP between the resistance and complex exercises. The findings show that there is a significant interaction for both warm-up exercises; [(F(1,29)=1275.57, p=0.000] for resistance exercise and [(F(1,29) = 1456.83, p= 0.000] for complex exercise. The retention analysis for PAP effect also indicates that there is a significant difference between the two warm-up activities in vertical jump performance. In conclusion, this study reveals that both exercises managed to increase PAP among volleyball players. However, complex exercise is suggested to be combined with the warm-up method as it can maintain a longer retention than resistance exercise.

Effects of the Proprioceptive Neuromuscular Facilitation Contraction Sequence on Motor Skill Learning-Related Increases in the Maximal Rate of Wrist Flexion Torque Development.

Background: The proprioceptive neuromuscular facilitation (PNF) reciprocal contraction pattern has the potential to increase the maximum rate of torque development. However, it is a more complex resistive exercise task and may interfere with improvements in the maximum rate of torque development due to motor skill learning, as observed for unidirectional contractions. The purpose of this study was to examine the cost-benefit of using the PNF exercise technique to increase the maximum rate of torque development.Methods: Twenty-six participants completed isometric maximal extension-to-flexion (experimental PNF group) or flexion-only (control group) contractions at the wrist. Ten of the assigned contractions were performed on each of three sessions separated by 48-h for skill acquisition. Retention was assessed with 5 contractions performed 2-weeks after acquisition. Torque and surface electromyographic (sEMG) activity were analyzed for evidence of facilitated contractions between groups, as well as alterations in muscle coordination assessed across test sessions. The criterion measures were: mean maximal isometric wrist flexion toque; the maximal rate of torque development (dτ/dtmax); root-mean-square error (RMSE) variability of the rate of torque versus torque phase-plane; the rate of wrist flexion muscle activation (Q30); a coactivation ratio for wrist flexor and extensor sEMG activity; and wrist flexor electromechanical delay (EMD).Results: There were no significant differences between groups with respect to maximal wrist flexion torque, dτ/dtmax or RMSE variability of torque trajectories. Both groups exhibited a progressive increase in maximal strength (+23.35% p < 0.01, η2 = 0.655) and in dτ/dtmax (+19.84% p = 0.08, η2 = 0.150) from the start of acquisition to retention. RMSE was lowest after a 2-week rest interval (−18.2% p = 0.04, η2 = 0.198). There were no significant differences between groups in the rate of muscle activation or the coactivation ratio. There was a reduction in coactivation that was retained after a 2-week rest interval (−32.60%, p = 0.02, η2 = 0.266). Alternatively, EMD was significantly greater in the experimental group (Δ 77.43%, p < 0.01, η2 = 0.809) across all sessions. However, both groups had a similar pattern of improvement to the third consecutive day of testing (−16.82%, p = 0.049, η2 = 0.189), but returned close to baseline value after the 2-week rest interval.Discussion: The wrist extension-to-flexion contraction pattern did not result in a greater maximal rate of torque development than simple contractions of the wrist flexors. There was no difference between groups with respect to motor skill learning. The main adaptation in neuromotor control was a decrease in coactivation, not the maximal rate of muscle activation.

Operating Room Time Prediction: An Application of Latent Class Analysis and Machine Learning

Objective: The objective of this work is to build a prediction model for Operating Room Time (ORT) to be used in an intelligent scheduling system. This prediction is a complex exercise due to its high variability and multiple influential variables. Materials and methods: We assessed a new strategy using Latent Class Analysis (LCA) and clustering methods to identify subgroups of procedures and surgeries that are combined with prediction models to improve ORT estimates. Three tree-based models are assessed, Classification and Regression Trees (CART), Conditional Random Forest (CFOREST) and Gradient Boosting Machine (GBM), under two scenarios: (i) basic dataset of predictors and (ii) complete dataset with binary procedures. To evaluate the model, we use a test dataset and a training dataset to tune parameters. Results and discussion: The best results are obtained with GBM model using the complete dataset and the grouping variables, with an operational accuracy of 57.3% in the test set. Conclusion: The results indicate the GBM model outperforms other models and it improves with the inclusion of the procedures as binary variables and the addition of the grouping variables obtained with LCA and hierarchical clustering that perform the identification of homogeneous groups of procedures and surgeries.

The theoretical-praxiological warm-up model (PPAT) for entertainer singers

The following article presents physical exercises and the theoretical-praxiological model for singers’ warm-up. The purpose of this paper is to streamline the warm-up for entertainer singers by using PPAT means. The development of technical and interpretive skills, implementation of PPAT relevant to the field and their improvement throughout the activity are some of the most important concerns of each entertainer singer. The complex method of physical and vocal training includes body gymnastics exercises, exercises of the muscular systems that participate in the emission of sound and vocal exercises. Complex exercises are recommended for maintaining mental and physical qualities, improving general motor skills and phono-articulatory movements. These are basic not just for the development of sound emission, but also for the prevention of the so-called professional diseases. The creative development of PPAT for future specialists has a benefic effect on intellectual, emotional-volitional and practical activity. The means, methods and forms of PAPT are aimed at optimally meeting the requirements of the educational, professional, social and daily life spheres of vocalists. PPAT, as a training factor for singers, includes the following: the greater the motor experience and perceptions of the vocalist are, the more perfect the coordination of movements determines a good physical training, the faster the new action is developed, because man can previously create a preliminary model of any motor act in his mind and reproduce it quickly. The essence of PPAT is the optimal use of resources, methods and forms of physical training, in order to achieve and maintain mental and physical qualities. The artistic activity of a vocalist has possibilities to integrate the influence on his spiritual growth and, in particular, on the improvement of his personality. It is important that the specialist in the field acts with interest, with a sufficient degree of independence, in other words creative, and the creative approach to actions is the basis of education.

How to Enable Collaboration in Open Government Data Ecosystems: A Public Platform Provider’s Perspective

Open Government Data (OGD) is an important driver for open innovation among public entities. However, extant research highlights a need for improved feedback loops, collaboration, and a more demand-driven publication of OGD. In this study, we explore how public platform providers can address this issue by enabling collaboration within OGD ecosystems, both in terms of the OGD, and any related Open Source Software (OSS) and standards. We conducted an exploratory multiple-case study of four OGD ecosystems with diverse characteristics, using a qualitative research approach. Based on the cases, we present a conceptual model that highlights different attributes of OGD ecosystems that may help public entities in designing and orchestrating new or existing OGD ecosystems. We conclude that enabling collaboration in an OGD ecosystem is a complex exercise yet believe that it offers ways for public entities in how they can leverage open innovation to address their goals and directives.

Clinical examination of the newborn’s foot is a complex exercise that requires a lot of sensitivity, practice and deep understanding of normal and pathological anatomy, and the clinical assessment of a child with congenital talipes equinovarus, or congenital clubfoot, must be complete and it should not be limited to a simple orthopedic evaluation of the foot; the search for a cause is a pressing concern. This narrative review article aims to provide the key information about clinical examination of children with congenital clubfoot; classification systems are also described. Clinical examination of children with congenital clubfoot is essential. In particular, it is important to evaluate the mental age of the child (developmental milestones), to rule out the presence of a spinal dysraphism, to eliminate a mild form of neurological disease (congenital myopathy or arthrogryposis), as well as to carefully examine the face and hands of the patient. The examination of the foot and the classification of the clubfoot deformity complete the clinical evaluation. In the end, the pediatric orthopedic surgeon must not underestimate any clinical signs, and must act as a pediatrician. This narrative review summarizes the key points in taking a history and performing a comprehensive clinical examination for patients with congenital clubfoot; the review also briefly describes the normal foot anatomy and growth as to give the reader the opportunity to better understand the morphological and functional modifications secondary to congenital clubfoot.

Automatic Detection of Irritable Bowel Syndrome for 3D Images Using Supervoxel and Graph Cut Algorithm

Medical image processing is a complex exercise and involves a number of stages to identify the disease in the arena of medical imaging. Irritable bowel syndrome is an acute disorder that causes intense abdominal pain and leads to changes in the bowel system. It gives rise to various indications like bleeding, bloating, celiac disease, gastric cancer, ulcer, etc. The system proposed here seeks to segment and classify each symptom of the irritable bowel syndrome individually with the aid of supervoxel segmentation algorithm. Features are extracted depending on the color, shape, and texture of the object. The extracted features are fed into the multi-support vector machine to identify the specific region in the medical image. The experiment provides the result of a test set 100 images stored in the data set which improves accuracy that refines the final output.

A Study on How to Use CHILDREN'S PARKS according to the Change in Population Composition

Purpose: Although children s parks are easily accessible from anywhere in the vicinity, there are many children s parks that children are ignoring. This study aims to provide a variety of activities to residents by utilizing these parks. In particular, these parks can be used as an alternative to crea ting a place for active play and effective exercise for the elderly who spend free time in an aging society. This study suggested using the existing children s play space as a complex play and exercise space with the elderly. Method: This paper selected 63 children s parks in Suseong-gu, Daegu Metropolitan City, and ana-lyzed them by dividing them into three residential types. Population change trends were investigated from 2005 to 2020, when children s parks were subdivided. This paper conducted a one -way ANOVA analysis to find out the difference by park facilities in children s parks. Post-hoc analysis was performed by the Scheffe test. To conduct the above statistical analysis, this paper used the Spss Statistics 21 sta-tistics program. Results: As a result of analyzing the change in the total population composition of Suseong-gu, where the children s park is located, the population of infants and children decreased, and the popula-tion of the elderly increased. The designation of children s parks has declined since the 1990s. It was found that the number of children by housing type decreased little by little every year. This paper ana-lyzed that the park area by residential type was the largest for children s parks located in mixed housing areas. In addition, it was found that many children s play facilities were installed in mixed residential areas. Conclusion: This study propose that if we increase the utilization rate of children s parks that lack user consideration and utilize children s parks within the living area, we can solve outdoor activities for the elderly according to the rapidly progressing aging age. In particular, if the children s park is made into a multi-purpose culture, sports, and amusement park that not only the elderly but also children and young people can use, it will be of great help to the utilization of the park.

Development of an experimental system for the twin-lift decommissioning operation

Hundreds of offshore platforms are approaching the end of their productive life and will require decommissioning within the next decade. Removal of a large offshore structure is a highly complex exercise that poses significant safety challenges. In this paper, we propose a new concept to remove large and heavy structures with a single lift, utilizing three semi-submerged vessels. Such a twin-lift solution for decommissioning involves an operation of lifting of a topside structure, carried on two semi-submerged vessels, to the third semi-submerged vessel. Although the method appears simple, it requires adequate stability using ballast tank, and synchronized motion of moving vessels, especially under environmental disturbances. In order to ensure efficiency and safety, we perform a wave tank test for such a twin-lift decommissioning solution. Some aspects of an experimental facility set-up for scaled model test with dynamic positioning (DP) system are described. It includes the layout of the experiment and details of the deck mating, DP and monitoring system. Preliminary experimental results are presented, to reveal that a simple controller combined with DP system is able to produce a robust and precise performance.
