MIXED CLASS TEACHING AS AN EMERGING TREND ACCELERATED BY COVID-19

The COVID-19 pandemic has essentially accelerated the pace of the teaching transformation. Mixed (also hyflex) class teaching has become indispensable in medical, engineering, teacher and other fields of education when only online teaching is not enough to ensure the continuity of the instruction. The research aim is to identify scenarios of mixed class teaching underpinning the elaboration of implications for higher education. The present research used both - theoretical and empirical methods. The theoretical methods included the analysis of scientific literature, theoretical modelling, systematisation, synthesis, comparison, and generalisation. The empirical study carried out in June 2021 was exploratory. Data were collected through the analysis of published studies. The collected data were processed via content analysis. The present research allows concluding that teaching has undergone significant changes in different historical periods. The findings of the empirical study facilitate the conclusion on the existence of two scenarios of mixed class teaching, namely HOT (Here or There) and COIL (Collaborative Online International Learning). Both scenarios are oriented to students’ learning, teaching in these scenarios is neither segmented nor structured. The novel contribution of the research is revealed in the implications on mixed class teaching for higher education. Future research work was proposed.

This study aims to explore the perceptions of Islamic scholars in Yogyakarta regarding the deradicalization of religion and the role of social media in religious deradicalization. This research uses a case study method which is part of qualitative research. Researchers collected data by conducting in-depth interviews via offline or online interviews via the Zoom application. Participants consisted of 16 male and female Islamic scholars coming from various backgrounds of Islamic organizations, such as Muhammadiyah, Nahdlatul Ulama, the Indonesian Islamic Da’wah Institute, Hizbut Tahrir Indonesia, and the Qur’an Tafsir Council. The location of this research is Yogyakarta Special Region. Interview data were analyzed using thematic analysis methods. This study of religious deradicalization found four major themes, namely strengthening awareness of being Indonesian, prioritizing an inclusive approach as a soft approach in fighting radicalism, promoting a deep understanding of Islam, and utilizing social media. This research can contribute to the government, religious leaders, educational institutions, and BNPT (National Counter-Terrorism Agency) where religious deradicalization programs need to be focused on a soft approach, involving the use of social media, targeting blind spot areas such as study programs of medical, engineering, and pharmacy at universities and ensuring mosques uncontrolled by radical groups.

Photodynamic and Photothermal Therapy of Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) is the most common primary liver tumor. It is ranked the sixth most common neoplasm and the third most common cause of cancer mortality. At present, the most common treatment for HCC is surgery, but the 5-year recurrence rates are still high. Patients with early stage HCC with few nodules can be treated with resection or radiofrequency ablation (RFA); while for multinodular HCC, transarterial chemoembolization (TACE) has been the first-line treatment. In recent years, based on medical engineering cooperation, nanotechnology has been increasingly applied to the treatment of cancer. Photodynamic therapy and photothermal therapy are effective for cancer. This paper summarizes the latest progress of photodynamic therapy and photothermal therapy for HCC, with the aim of providing new ideas for the treatment of HCC.

Stretchable and anti-impact iontronic pressure sensor with an ultrabroad linear range for biophysical monitoring and deep learning-aided knee rehabilitation

Monitoring biophysical signals such as body or organ movements and other physical phenomena is necessary for patient rehabilitation. However, stretchable flexible pressure sensors with high sensitivity and a broad range that can meet these requirements are still lacking. Herein, we successfully monitored various vital biophysical features and implemented in-sensor dynamic deep learning for knee rehabilitation using an ultrabroad linear range and high-sensitivity stretchable iontronic pressure sensor (SIPS). We optimized the topological structure and material composition of the electrode to build a fully stretching on-skin sensor. The high sensitivity (12.43 kPa−1), ultrabroad linear sensing range (1 MPa), high pressure resolution (6.4 Pa), long-term durability (no decay after 12000 cycles), and excellent stretchability (up to 20%) allow the sensor to maintain operating stability, even in emergency cases with a high sudden impact force (near 1 MPa) applied to the sensor. As a practical demonstration, the SIPS can positively track biophysical signals such as pulse waves, muscle movements, and plantar pressure. Importantly, with the help of a neuro-inspired fully convolutional network algorithm, the SIPS can accurately predict knee joint postures for better rehabilitation after orthopedic surgery. Our SIPS has potential as a promising candidate for wearable electronics and artificial intelligent medical engineering owing to its unique high signal-to-noise ratio and ultrabroad linear range.

A Descriptive Study to Assess the Impact of Mobile Phone Usage on Human Behaviour Among Undergraduate Students of Lucknow

Background of the study: Students were found to use mobile phone excessively. The pattern of mobile phone use among the students may signal the evolution of mobile phone use from a habit to an addiction.[5] Usage of mobile phones adversely affect student concentration, psychosocial wellbeing and their physiological health which are areas that need attention. The problem is that the use of mobile phone among students has become a habit.[3] Research shows that there is a difference between students’ performance and commitment to academics in lecture rooms from those who use mobile phones during lecture, inattentiveness, and non- participation in academic assignments or field work.[7] Findings of a study indicates that mobile phones play a large part in the daily life of medical student. Therefore, its impact on psychological and health should be discussed among the students to prevent the harmful effects of mobile phones use.[8] Objective of this study is to assess the impact of mobile phone usage on behavior change among undergraduate students and to find out the association between the impact of mobile phone usage on behavior change among undergraduate students with the selected demographic variable. Materials and Methods: Descriptive research design was utilized in this study. Through non discriminative snow ball sampling technique 100 undergraduate students of different disciplines like medical, engineering, agricultural and other science were selected for this study. Self-administered online questionnaire was used to gather the data from the participants. Descriptive and inferential statistics was used to analyze the data. Results: impact of mobile phones among 1% of undergraduate students is mild, 94% of undergraduate students had moderate impact and remaining 5% of them reported that the impact of mobile phone on their human behavior is severe. The overall mean impact score was 91.21 and obtained SD was 22.34. Conclusion: Results of this study shows that the usage of mobile phone has moderate to severe impact among the behavior of the undergraduate students. Though the need of mobile phone is inevitable there needs have to be balanced between time spent with these devices, and without them. Without a set balance, people will continue to become more obsessed and consumed by technology, and there is a concern that humans will lose all closeness and affection that can come from personalized conversations.
