The Place of e-learning in ALS Teaching

This paper presents the place of e-learning methods in the teaching of Advanced Life Support (ALS) to second year medical students. The described course lasts 30 hours and consists of lectures, seminars, and classes. Numerous modifications of the course were introduced in the past and at the moment electronic learning methods are being improved with new ones being added as well. The following have been implemented: 1. e-learning presentations instead of lectures; 2. recording own instructional movie demonstrating advanced cardiopulmonary resuscitation; 3. a change in the method of conducting practical classes consisting in recording the medical procedures performed by students with a camera. Although e-learning plays an important role in ALS teaching, it cannot completely replace on-site classes. Thus, ALS without any practice to acquire resuscitation skills is impossible.

Translation: A Key Component of a Hundred-Year Project

The Emory-Tibet Science Initiative (ETSI) has embarked on a historic endeavor of introducing a systematic and sustainable science education program within the traditional Tibetan monastic institutions. His Holiness the Dalai Lama, who conceived and supports this initiative, calls it a hundred-year project. From the very beginning, translation from English to Tibetan has been an integral part of this project because of the need to prepare course materials as well as to facilitate on-site classes and lab activities in the Tibetan language. Our translation process involves not just conveying novel and foreign concepts across cultures but doing so with a scientific language peppered with technical terms that are not readily representable in the target language. In addition to the linguistic barriers, cultural and technical ones further complicate the process of communication. A case in point is the concept of life, or correlation versus causation, or the view that consciousness is an emergent property of the brain, where each construct has its corresponding but differing concept in Tibetan Buddhism. When engaging with such existing parallel yet divergent terms or concepts, the translators must strike a delicate balance and avoid forsaking the distinctive characteristics and connotations involved. In this article, the ETSI translation team shares its journey—highlighting the needs felt, challenges faced, and solutions sought. We discuss the translation principles guiding our work and the handling of such scientific features as graphs, acronyms, units, chemical names, and formulas. We hope our work will inspire other similar projects around the globe and encourage them to continue bridging barriers to cross-cultural dialogues, promoting cross-fertilization of knowledge for human flourishing.

STUDENT PERCEPTIONS OF ECUADORIAN VIRTUAL PLATFORMS DURING THE COVID-19 PANDEMIC

In February 2020 Ecuador declared a health emergency due to the Covid-19 pandemic. On-site classes were suspended. The Ecuadorian university population does not adapt to virtual educational platforms. The objective of the study was to analyse student perception of Ecuadorian educational platforms in higher education during the COVID-19 pandemic. The study was quantitative. The sample was non-probabilistic participatory, consisting of students from different universities in the Province of Chimborazo. For data collection, a questionnaire with four study variables was applied. The results were analysed with T student and MANOVA. There is a positive perception of students using the educational platforms. There were significant statistical differences according to gender variables, contrary to the levels of study and location, there is a greater sympathetic affection of students when receiving virtual classes by female teachers. It can be concluded that the Covid-19 pandemic accelerated the adoption of online learning by higher education institutions.

Seismic hazard microzonation of Bengkulu City, Indonesia

It has been known that Bengkulu City (Indonesia) is vulnerable to undergo seismic damage. This study is initiated by measuring horizontal to vertical spectral ratio (H/V) to sites in Bengkulu City using microtremor. The inversion analysis is performed to generate shear wave velocity profile. Hundreds of sites are investigated in this study. The results show that observed H/V is consistent with the theoretical H/V. National Earthquake Hazard Reduction Program code is adopted to classify the site class. The results also exhibit that Bengkulu City is dominated by Site Classes C and D. In general, this study could lead local government to consider seismic hazard mitigation for spatial plan.

The 2018 update of the US National Seismic Hazard Model: Additional period and site class data

As part of the update of the 2018 National Seismic Hazard Model (NSHM) for the conterminous United States (CONUS), new ground motion and site effect models for the central and eastern United States were incorporated, as well as basin depths from local seismic velocity models in four western US (WUS) urban areas. These additions allow us, for the first time, to calculate probabilistic seismic hazard curves for an expanded set of spectral periods (0.01 to 10 s) and site classes (VS30 = 150 to 1500 m/s) for the CONUS, as well as account for amplification of long-period ground motions in deep sedimentary basins in the Los Angeles, San Francisco Bay, Seattle, and Salt Lake City areas. Two sets of 2018 NSHM hazard data (hazard curves and uniform-hazard ground motions) are available: (1) 0.05°-latitude-by-0.05°-longitude gridded data for the CONUS and (2) higher resolution 0.01°-latitude-by-0.01°-longitude gridded data for the four WUS basins. Both sets of data contain basin effects in the WUS deep sedimentary basins. Uniform-hazard ground motion data are interpolated for 2, 5, and 10% probability of exceedance in 50 years from the hazard curves. The gridded data for the hazard curves and uniform-hazard ground motions, for all periods and site classes, are available for download at the U.S. Geological Survey ScienceBase Catalog ( https://doi.org/10.5066/P9RQMREV ). The design ground motions derived from the hazard curves have been accepted by the Building Seismic Safety Council for adoption in the 2020 National Earthquake Hazard Reduction Program Recommended Seismic Provisions.

Seismic Analysis of a Large LNG Tank Considering Different Site Conditions

Seismic resilience of critical infrastructure, such as liquefied natural gas (LNG) storage tanks, is essential to the safety and economic well-being of the general public. This paper studies the effect of different ground motions on large LNG storage tanks under four different site conditions. Key parameters of structural design and dynamic analysis, including von Mises stress of outer and inner tanks, tip displacement, and base shear, are analyzed to directly evaluate the safety performance of the large LNG tanks. Because the size of an LNG tank is too large to perform any experiments on a physical prototype, Smoothed Particle Hydrodynamics-Finite Element Method (SPH-FEM) simulation is used as a feasible and efficient method to predict its seismic response. First, the accuracy of the SPH-FEM method is verified by comparing sloshing frequencies obtained from theoretical formulation to experimental results and SPH-FEM models. Then, the seismic response of a real-life 160,000 m3 LNG prestressed storage tank is evaluated with different liquid depths under four site classes. Simulation results show that the tip displacements of the LNG tank at liquid levels of 25% and 50% under site class IV are nearly identical to that of 75% and 100% under site class II. In addition, the maximum von Mises stress of the inner tanks exceeds 500 MPa in all four site classes and jeopardizes the structural integrity of large LNG tanks. As a result, optimization of structural design and the establishment of an early warning system are imperative to the safety of LNG tanks at high liquid levels.
