Transition to Online Learning: Implementing the TPACK Framework by English Teachers due to the COVID-19 Pandemic

The objectives of this research is to explore how the English teachers implement TPACK in online learning context and to know the challenges faced by the English teachers in implementing TPACK. There were several studies in the implementation of TPACK, but still less on the discussion about the challenges that the English teachers faced while implementing it, particularly in the online learning due to the COVID-19 pandemic. This study employed a descriptive design with a qualitative approach, which were analyzed descriptively through reducing inappropriate data, displaying and concluding data. The results of the data revealed that the English teachers of Bunga Bangsa Islamic Junior High School Samarinda had implemented TPACK in online learning context by using WhatsApp, Zoom meeting and Google Classroom as the technologies used to teaching, conducting demonstration and recitation method as the pedagogy to teach about “object pronoun” and “will and going to” as the content. There are some challenges faced by the English teachers when they implemented TPACK in online learning context such as limited quota, bad signal of internet, students’ behavior and adapt to the applications used such as WhatsApp, Zoom meeting and Google Classroom.Tujuan dari penelitian ini adalah untuk mengeksplorasi bagaimana guru bahasa Inggris menerapkan TPACK dalam konteks pembelajaran online dan untuk mengetahui tantangan yang dihadapi oleh guru bahasa Inggris ketika mereka menerapkan TPACK dalam konteks pembelajaran online.

A geographical analysis of ethnic distribution of jaw ameloblastoma in Nigerians

Introduction: Ameloblastoma is the most common odontogenic tumour in Nigeria. A definite geographic variation has been observed in the frequency of odontogenic tumors from different parts of the world. However, there is no study on the regional variations in Nigeria. Hence, this study was designed to document the ethnic and geographical distribution of jaw ameloblastoma in Nigeria.Methods: Archival data on ameloblastoma from 10 health facilities were obtained. Global Moran’s I detected geographic clustering in its distribution while Local Getis Ord indicated the location of ameloblastoma clusters. Chi-square tested associations between variables at 0.05 level of significance.Results: A total of 1,246 ameloblastoma cases were recorded in Nigeria. Besides substantial state variations, a South-North gradient was noticed in its distribution. Significant positive spatial autocorrelation was observed in the three major groups while ameloblas- toma hotspots were found in the SouthWestern and Northwestern Nigeria. The Igbos had a higher prevalence of ameloblastoma outside their home region than within.Conclusion: The study hypothesized that the geographical distribution of ameloblastoma in Nigeria is the result of all or one of the following:  the country’s tropical climate, migration patterns and health seeking behavior. Hopefully, these claims should lead to further enquiry on the underlying causes.Keywords: Ameloblastoma, ethnicity, spatial analysis, Nigeria

Changing the network design to reduce telecommunication cost to support the business growth goal of a multinational consumer goods company in Greater China

The high telecommunications costs has been considered as a major barrier in enabling P&G to significantly grow in China. This project aimed to decrease these costs using the action research framework. There were two action research cycles completed in this initiative. The first cycle focused on reducing the costs of bandwidth by changing the overall network design, while the second cycle revolved around reducing the costs of call conferencing in the country. I orchestrated the collaboration between different organizations to properly construct the issue, plan and implement actions and finally evaluate the actions chosen. The collaboration was done through formal and informal meetings, board reviews, focus group discussions (FGDs) and remote interviews. Frameworks such as 5-Whys analysis were used to uncover the root causes of the issues in each cycle of the action research. The high bandwidth costs in China was driven by the lack of presence of P&Gs current transport vendor in the country while the high call conferencing costs was due to the high reliance on public telephone network. Changes on the infrastructure design, using the IT Infrastructure Library (ITIL) framework, were carried out to address these root causes. After the implementation of the two cycles, a combined savings of about $4 Million was delivered for the fiscal year and improving user experience without negative impacting the company\u27s operation in the country

Tactile sensing feedback for medical palpation in Minimally Invasive Surgeries (MIS)

Minimally Invasive Surgeries (MIS) are major operations through small incisions often using miniaturized high-tech systems, to minimize the trauma of surgical procedure. However such procedures deprive surgeons one of their most important ability-ability to touch and palpate. It also limits the dexterity, depth of perception and hand - eye coordination. The study focuses on the development of an effective mechanism of relaying the information across the surgical area to the surgeon through a tactile sensing feedback system. The design sensor system should be ergonomically sound, has high reproducibility of results so that it could be fitting for medical use. The project utilizes nine (9) circular tactile sensors formed in a 3x3 matrix to be interfaced data acquisition system through a Zilog Z8 Encore! 6421. The pressure distribution sensed by the feedback system will generate a 3D image to be shown in the constructed Graphical User Interface (GUI)
