Ġ.F. Abela Junior College, commonly known as the Junior College (JC), is a further education college in Msida, Malta, which prepares students for the Matriculation Certificate. It was established in 1995 by the University of Malta. It is named after the 17th-century Maltese historian Giovanni Francesco Abela.Students may choose from a range of subjects and must take two subjects at Advanced Level, three at Intermediate Level, as well as Systems of Knowledge. Since the college forms part of the University of Malta, students are able to become familiar with the University campus. College and university students collaborate on cultural projects such as concerts, drama, sport, student exchanges, debates and seminars.The Junior College is housed in a Modernist building which was constructed between 1962 and 1966 as the Malta College of Arts, Science and Technology to designs of Victor Anastasi.
This study presents a data-driven approach to compute walkability indicators from open-data sources. We compare Phnom Penh and Ho Chi Minh City, two Southeast Asian cities that share cultural, historical, and economic similarities. We inspect street network connectivity, population density, building density, facilities density, and elevation range. Overall, the findings suggest that Phnom Penh exhibits higher walkability due to its greater network density, population density, and facility density, fostering greater city-wide connectivity. In contrast, Ho Chi Minh City, a key economic hub in Vietnam, shows lower walkability metrics, possibly influenced by higher urban development and income levels. Wealthier residents may prefer vehicular transportation, supported by the city's robust GDP-driven infrastructure.
Introduction: We have been developing dental fiberscopes （FS） which are used for visual examination of the intricate morphology of the canal system and inaccessible areas, such as periapical lesions, periodontal pockets, and so on. This study evaluated the effectiveness of FS-assisted Er:YAG laser irradiation in comparison to microscope （MS）-assisted Er:YAG laser irradiation in root canal treatment. Method: The FS comprises three parts: image fibers （6,000 pixels, field depth: 5mm）, light guides and a working channel for the laser fiber. The outer diameter of the fiberscope needle with a gradual curve is 1.1mm. Twenty maxillary right central incisor tooth models with root canals （size: #60, taper: 6/100, root canal length: 10mm） that were mesiodistally separable were prepared. A black dot was marked immediately beneath the canal orifice of each tooth model that was cut in half beforehand. Five dental practitioners with experience in the FS and Er:YAG laser participated in the experiment. To remove the dot, the tooth models were treated with the Er:YAG laser assisted either with FS or MS. The laser beam was applied to each model at 50mJ, 10 pps with a water spray to cool the area being treated for 5 minutes. Then, the canal surface was observed and the removed area of the black dot was calculated. Results: The mean rates of removed area were 41.7±36.1％ （FS） and 14.3±24.0％ （MS）, respectively. The mean rate of removed area in the FS group was significantly larger than that in the MS group （Mann–Whitney U test, p ＜ 0.05）. Discussion: The MS has rapidly become a widely used tool for finding canals, diagnosing and treating cracks and fractures, repairing perforations, and considering different treatment options. Although the image quality of the FS is inferior to that of the MS, the FS is considered useful in clinical settings as it also enables visualization of root canals in detail. Furthermore, the FS allows the operator to visualize difficult-to-reach areas where straight-line access is not available by the MS. Further investigation is needed to clarify the advantages and disadvantages of the FS, as well as collecting and analyzing more basic experimental data. Conclusion: The results suggest that the application of FS-assisted Er:YAG laser irradiation could lead to better clinical outcomes in comparison to MS-assisted Er:YAG laser irradiation in root canal treatment.
In Japan, schools were closed from March to May 2020 due to COVID-19. As most schools could not offer online classes, in April 2020, the government implemented the GIGA School Concept to accelerate the development of information and communication technology (ICT) in primary and secondary education. A case study of a secondary school was conducted. The results show that the principal exercised four types of leadership based on firm values: (1) sharing the vision and motivating teachers, (2) distributed leadership, (3) instructional leadership, and (4) responding appropriately to a pandemic. At the national levels, the main focus was on responding to the pandemic and implementing the GIGA School Initiative policy, while the schools were following more multifaceted leadership for improvement.
