Authors: Kathiravan S. , Thanigaivelan R. , Suresh P. 
Published: January 2023

Abstract
Today, researchers across the world focus on sustainable products, and, accordingly, it is now imperative to develop sustainable MMCs. In line with this, ongoing experimental work aims to fabricate aluminum 6061 MMC with ground granulated blast furnace slag (GGBS) and study the micro-structural and machinability characteristics. A liquid state stir casting setup is used to melt aluminum 6061 alloy and reinforced with 2.5 wt.%, 5.0 wt.%, and 7.5 wt.% of GGBS. X-ray diffraction (XRD) studies were used to identify the chemical elements that were present in the fabricated samples. In order to observe the formation of any secondary elements, energy-dispersive X-ray spectroscopy and scanning electron microscopy (SEM) were utilized on the cast composites. Through the milling process, the influence of the GGBS reinforcement composition on the surface roughness (SR) and material removal rate (MRR) of aluminum 6061 MMC was examined, considering the parameters of spindle speed, feed rate, depth of cut, and reinforcement composition percentage. The L9 orthogonal array (OA) was used to investigate the results of the experiments, and the Taguchi technique was used to optimize the process. The best MRR value was produced by the feed rate (B3) of 260 mm3/min and the depth of cut (C3) of 0.75 mm. The study ascertained that the lower SR value is attained corresponding to a spindle speed of 1,250 rpm, a feed rate of 220 mm3/min, a depth of cut of 0.25 mm, and a reinforcement composition percentage of Al 6061 with 5% GGBS.
Participation and digital non-formal learning environments
Authors: Spinelli Angela 
Published: January 2023

Abstract
Participation is a key issue in understanding didactic dynamics. On the one hand, youth participatory cultures are described as incorporating gaming, multitasking, transmedia navigation and networking; on the other hand, the pre-digital meaning of participation retains a political value related to individual commitment for the common good and to socio-constructivist learning design. There is a connection among community, participation and learning, as the tradition of communities of practice highlights (Wenger, 1998, 2000).
The present article introduces and discusses the results of the research focussing on the course for civil protection operators engaged in voluntary public assistance service. The course was delivered online following the lockdown measures enacted in response to the SARS-CoV-2 pandemic. Three specific dimensions were examined: a) the trainer’s role; b) group dynamics and c) online participation. It was possible to compare these data with those collected in occasion of other training courses delivered face to face before the 2020 healthcare emergency.
The research was conducted as a multimethod case study using quantitative and qualitative tools.
Coding and childhood between play and learning: Research on the impact of coding in the learning of 4-year-olds
Authors: Pelizzari Federica , Marangi Michele , Rivoltella Pier Cesare , Peretti Giulia , Massaro Davide , Villani Daniela 
Published: January 2023

Abstract
We propose the results of a research that combines the educational and psychological media approach, to verify the pedagogical potential of coding and robotics in the learning processes of 4-year-old children at the cognitive and socio-relational level.
The study investigated the impact of unplugged and plugged coding on the skills of spatiality, movement and problem-solving skills, storage and decoding of progressively more complex indications, and single-group interaction of 51 children and three kindergartens using storytelling and the educational robot Cubetto.
The work is based on the research carried out by Lee (2020) on the inclusion of coding in early childhood, the theoretical references of Wing (2010) about computational thinking and the theoretical frameworks proposed by Bers (2020) regarding coding as a playful dimension.
The data collected through the quantitative and qualitative tools of a pre- and post-intervention questionnaire to educators and a checklist of observations on children recorded the following:
• an increase in children’s space, motor and information-storage/decoding skills;
• a change in children’s collaborative skills when comparing the results of the plugged and unplugged coding workshops and
• the impact of coding to increase children’s performance skills through narrative dimension and play.
A personalized feedback system to support teacher training
Authors: De Angelis Marta , Miranda Sergio 
Published: January 2023

Abstract
This paper aims to illustrate an automated system developed to give formative and personalized feedback to teachers in training. It is an expert system (Paviotti, Rossi & Zarka, 2012) that uses concrete examples, cases and scenarios to guide the engaged learners (Leake, 1996). In this regard, this system is able to create questionnaires, deliver them, collect and analyze data, send feedback to the participants to provide information about their beliefs and behaviors about teaching and learning processes. Far from constituting an assessment of teaching practices, the automated feedback demonstrates its usefulness in identifying teachers’ mindframes at an early stage, so as to be able to implement more specific and personalized training. This allows its application to be extended to further training areas as well as constituting an effective approach for need analysis and a preparatory action for numerous training activities (guided discussion with experts, observation on practice, modeling, etc.).
One year later: digitalized higher education in pandemic times. An international study of higher education faculty’s response
Authors: Trevisan Ottavia , De Rossi Marina 
Published: January 2023

Abstract
The paper describes the international research conducted in collaboration between the University of Padova, University of North Texas, and Windesheim University of Applied Sciences. The study explores how higher education faculty involved in professionalizing courses for the educational area perceive the pandemic-induced transition to digitalized education (DE), after one year of experience with it.
This paper introduces the second phase of a research study that began as early as spring 2020, with an online survey distributed worldwide. It seeks to investigate possible changes after one year of digitalized education related to (1) perceptions of institutional support and professional training offered; (2) potential and challenges of DE; and (3) professional intentions for future uses of DE. Details on the instrument’s reliability and structure will also be provided.
We are exploring how the DE is changing teachers’ routines and whether these changes are paving the way for collaborative, reflective, and student-centred approaches that could have long-term consequences. This is to help focus future training pathways to better support teachers in teaching effectively and efficiently for learning, both in times of crisis and in times of normalcy.
What kind of teaching in the post-digital era? The challenges of schools and universities after the pandemic: An explorative survey at University of Bari Aldo Moro
Authors: Fornasari Alberto , Conte Matteo 
Published: January 2023

Abstract
All around the world, schools and universities should re-think and update teaching to adjust to technological changes and exploit their potentialities by means of hybrid teaching (Limone, 2013). Considering teaching in presence as absolutely good and online teaching as bad and necessary only during the pandemic is ideological, reductive and wrong (Ferri, Moriggi, 2018). If properly used in an ad-hoc pedagogical approach, technology represents an opportunity for students (Bonaiuti, Dipace, 2021), who can participate in training and updating processes and better adapt to changes. The long and complex post-pandemic period should allow the experimentation of a better integration between teaching in the classroom and technologically ‘augmented’ teaching. The process of digitalisation and methodological innovation should become permanent, as suggested in Mission number 4 – Education and Research of the NPRR. This was the starting point for an explorative survey (Lucisano, Salerni, 2002) conducted with 400 students of the University of Bari in order to research their challenges and levels of satisfaction with the online courses attended in the a.a. 2020/2021. The survey shows the difficulties with distance teaching and presents an overview on possible future blended approaches.
Representation of learning in the post-digital: students’ dropout predictive models with artificial intelligence algorithms
Authors: Zanellati Andrea , Macauda Anita , Panciroli Chiara , Gabbrielli Maurizio 
Published: January 2023

Abstract
Within scientific debate on post-digital and education, we present a position paper to describe a research project aimed at the design of a predictive model for students’ low achievements in mathematics in Italy. The model is based on the INVALSI data set, an Italian large-scale assessment test, and we use decision trees as the classification algorithm. In designing this tool, we aim to overcome the use of economic, social, and cultural context indices as main factors for the prediction of a learning gap occurrence. Indeed, we want to include a suitable representation of students’ learning in the model, by exploiting the data collected through the INVALSI tests. We resort to a knowledge-based approach to address this issue and specifically, we try to understand what knowledge is introduced into the model through the representation of learning. In this sense, our proposal allows a students’ learning encoding, which is transferable to different students’ cohort. Furthermore, the encoding methods may be applied to other large-scale assessments test. Hence, we aim to contribute to a debate on knowledge representation in AI tool for education.
Hate Speech Research: Algorithmic and Qualitative Evaluations. A Case Study of Anti-Gypsy Hate on Twitter
Authors: Pasta Stefano 
Published: January 2023

Abstract
Hate speech may be the research focus of the interdisciplinary field of hate studies, but it is also a difficult phenomenon to define. Internationally, there are several detection studies on automatically detecting hate speech. They can be grouped according to two approaches: the first includes searching using only machine learning methods, while the second includes studies that combine automatic searching with human classification. The case study on anti-Gypsy hate in Italian on Twitter in the second half of 2020 falls into the second category, and its methods are outlined here. Based on the results (annotation as ‘hate’/‘non-hate’, identification of forms of rhetoric and anti-Gypsyism), the researchers propose classifying online content according to seven indicators called the ‘spectrum of online hate’.

Objetivo: Analisar a epidemiologia, transmissão, prevenção, aspectos clínicos e tratamentos da Neurocisticercose (NCC). Revisão bibliográfica: A cisticercose será gerada quando houver ingestão de ovos da Taenia solium, seja por meio de água contaminada ou alimentos, em decorrência das más condições higiênica e sanitária. A NCC é uma infecção parasitária que afeta o sistema nervoso central, pois, ao se instalar nos tecidos, os cisticercos sofrem degeneração provocada pelo sistema imunológico do hospedeiro, promovendo um processo inflamatório intenso nos tecidos afetados. As manifestações clínicas mais comuns da doença incluem cefaléia, distúrbios psíquicos, síndrome de hipertensão intracraniana, crises epilépticas, meningite cisticercótica, forma apoplética ou endarterítica e síndrome medular. Considerações finais: Abstrai-se que a neurocisticercose não está erradicada e ainda é endêmica em alguns países, como o Brasil, destacando uma maior prevalência de casos de NCC em países de baixa renda. Em síntese, para definir a melhor terapêutica é essencial identificar a forma de apresentação da doença, bem como o número de cisticercos presentes, se ativos ou inativos e sua localização. Para isso, é fundamental que a equipe multiprofissional esteja munida de recursos diagnósticos, suporte neurológico e infectológico, para que possa viabilizar a melhor forma de tratamento.
Effect of platelet counts and activator in platelet-rich plasma on the treatment of androgenetic alopecia, split-head comparison: A randomised, double-blind study
Authors: Singh Satyendra K , Singh Shailesh 
Published: January 2023

Background
Androgenetic alopecia is a common, chronic, non-scarring alopecia. It is characterised by stepwise miniaturisation of the hair follicles, due to alteration in the hair cycle dynamics, leading to the transformation of terminal hair follicles into a vellus ones. Oral finasteride and topical minoxidil are the only approved drugs for treating this condition. Due to a limited number of effective therapies for androgenetic alopecia, platelet-rich plasma may be an effective alternative treatment.

Aims
To study the effect of activator in platelet-rich plasma and baseline platelet count in platelet-rich plasma on the treatment of androgenetic alopecia.

Methods
A randomised, double-blind split-head comparative study. The sample size was calculated and randomisation was done. Patients with androgenetic alopecia were allocated into two groups; in the first group, autologous activated platelet-rich plasma was injected in the right half of the affected scalp and autologous non-activated platelet-rich plasma was injected in the left half of the affected scalp and vice versa in the second group. Patients were also categorised on the basis of platelet counts in their platelet-rich plasma in three groups; group A (6-8 lakh/mm3), group B (8.1-10 lakh/mm3) and group C (>10 lakh/mm3). Interventions were done monthly for three months and followed up for the next three months. Effects of interventions were assessed by hair density, hair thickness, patient self-assessment and clinical photography.

Results
A total of 80 patients were included in the study. Activated platelet-rich plasma produced significant improvement of hair density after four months and hair thickness at 6 months. An increase in platelet count led to a significant increase in hair density and hair thickness after three and four months respectively and a highly significant increase in both parameters at the end of the study.

Limitations
Long-term follow-up of cases was not done and no measurement of vellus hair count was done.

Conclusion
There is a significant effect of activator and platelet count of the platelet-rich plasma on hair density as well as hair thickness.

Published: January 2023

<p><em>Existence of coffee shops now in the Medan city has greatly increased. Of course this triggers competition between coffee shops, so that every coffee shop owner must think about their efforts to face their competitors. Then an optimal marketing strategy is needed. To determine the optimal marketing strategy, game theory is used using the 7P marketing mix strategy, namely Product, Price, Place, Promotion, People, Process and Physical Evidence. The coffee shops that are the object of this study are the DWS Coffee Shop and the Khup Kupi Coffee Shop. In assessing the marketing strategies used by each coffee shop, the researcher distributed a questionnaire to a number of coffee shop customers, therefore the researcher used Probability Sampling. The analysis technique used is descriptive test, validity test, reliability test and game theory which are processed using POM QM 5.0. From the results of the research that has been tested, it was found that the DWS Coffee Shop won the Price, Process, and Physical Evidance strategy, while the Khup Kupi coffee shop won the Product, Place, Promotion and People strategy. In this study, the results showed that both coffee shops have a saddle point of 788, which means that the two coffee shops have tight competition. And in this study also according to the results of the test results of the DWS Coffee Shop and Khup Kupi Coffee Shop simultaneously using Physical Evidance with points of 1 indicated.</em></p>
