“…Local area-based anticipatory projects can create framework changes that are far-reaching and that demonstrate a critical and robust impact on a population. This section investigates four classes of such efforts (Jefferies, 2018) environmental methodologies, social advertising and general welfare instruction, welfare advancement, and strategy change. Different models of nature have been created that consolidate ideas such as assets, social environment, courses of existence and learning cycles, and social settings.…”

This study aims to optimize health leadership in preventing Covid-19 from an early age in the village. The author believes that health status is determined by treatment; prevention can be more effective and efficient. We collect public health literature from many databases of public health publications. We start from the journal Esavier, Medpub, Google Book, and several websites that discuss public health issues at home and abroad. We are targeting based data published in the last ten years to find the latest data and validity. The research involves a data coding system, high evaluation, and conclusion drawing in order to be able to answer research questions with high reliability. We conclude that health leadership is characteristic of how medical roles lead people to health. Value health and maintain it until community members find physical and mental health. The medical team minimizes stress by communicating openly and creating a healthy and safe environment for its citizens' creative thinking and expression. These results are helpful for the development of literature and public health applications.

“…Furthermore, this information is considerably more up-to-date, than other data sources on ABWs, such as industrial whaling catches (spanning 1930-1965), IDCR-SOWER visual surveys (spanning 1978 (Branch, 2007) and SOWER passive acoustic surveys (spanning 1997-2009) (Shabangu et al, 2017;Shabangu, 2020). Contemporary sonobuoy data may be useful for understanding the present-day distribution of ABWs in a changing climate (Read, 2023;Stewart et al, 2023), or in the context of changing krill abundance, distribution, and fishing practices in the Southern Ocean (Jefferies, 2018;Kawaguchi and Nicol, 2020;Pallin et al, 2023;Trathan, 2023a, b).…”

Seven passive acoustic surveys for marine mammal sounds were conducted by deploying sonobuoys along ship tracks during Antarctic voyages spanning years 2006-2021. These surveys included nearly 330° of longitude throughout Antarctic (south of 60°S) and sub-Antarctic (between 50-60°S) latitudes. Here, we summarise the presence of calls from critically endangered Antarctic blue whales (Balaenoptera musculus intermedia) detected on all seven of these surveys. We describe and compare the spatial distribution of detections of three different types of Antarctic blue whale calls: unit-A, Z-calls, and D-calls. Three sets of voyages partially overlapped spatially but in different years, providing three regions (Indian Sector, Dumont d’Urville Sea, Ross Sea) to investigate differences over time for these three different call types. The proportion of sonobuoys with calls present was significantly higher in the more recent years for seven of the 15 combinations of years, regions, and call type. The proportion of sonobuoys with calls present was significantly lower only for one of the 15 combinations (unit A in the Ross Sea between 2015 vs 2017), and not significantly different for the remaining seven pairwise comparisons. We discuss possible explanations for these observations including: differences in probability of detection, whale behaviour, whale distribution, and abundance. These explanations are not mutually exclusive and cannot yet be resolved without application of complex analytical methods and collection of additional data. Lastly, we discuss future work that could help clarify the contributions of each of these potential drivers of acoustic detection. We propose continued acoustic data collection, application of new analytical methods, and collection of other synergistic data from Antarctic blue whales on their feeding grounds as a basis for future work on this species. This could provide a cost effective and holistic means of monitoring their status after the effects of 20th century industrial whaling, as well as their responses to natural and anthropogenic changes to their main prey, Antarctic krill, and a changing climate.
