Studies on Saturation Diving in Poland and Practical Application of their Findings. Part 2A. Developing a Polish System of Saturation Diving in the 1980s and 1990s
Authors: Skrzyński Stanisław , Grzeczka Grzegorz 
Published: July 2023

Abstract
This is another from the series of papers discussing studies on saturation diving technology and its use in Poland. This part explains the specificities of the Polish context and achievements against the backdrop of economic and historical circumstances. It describes how the central base for saturation diving came into being in the times of economic collapse in the country. At that time, the shipbuilding industry was the driving force behind research on saturation diving as a cornerstone for building a framework for diving systems to be exported to other countries to secure the extraction of assets from the sea shelf. The paper introduces the readers to the efforts of animators and protagonists of that period of underwater research in Poland whose achievements are continued until to-date. The second part of the paper shows how the Polish system of saturation diving was created. The article also considers the technical and organisational aspects of the first saturation diving experiences and the history of the Polish method of decompression for saturation diving. To accomplish this difficult task, it was crucial to ensure a solid industrial and academic base working for the defence sector and assisted by relevant state agencies. A multiannual CPBR programme was also set up with measures 9.2 and 9.5 dealing with medicine and technology which resulted in the development of a diving system with its organization, medical support and reliable technology. Outcomes of this programme are still being implemented today. Despite progress made in medicine, technology, and organisation issues involved in saturation diving are still pertinent because independently of their complexity and high cost this type of diving is the most efficient and allows for very deep diving operations up to 400-500 m.
An Attempt to Assess the Effectiveness of a Rescue and Starting Jump as Part of Activities Carried Out in Designated Water Areas Directly in Deep Water
Authors: Kaca Marcin , Siermontowski Piotr 
Published: July 2023

Abstract
Water rescue is constantly looking for solutions to improve the effectiveness of its operations. One of the elements of an action carried out directly in water is the rescue jump, whose effectiveness may determine the quality and success of the action taken. Therefore, a study was carried out to assess the effectiveness of a rescuer reaching a drowning person depending on the method of entry into the water. Comparisons were made between a traditional rescue jump (forward or stride entry) and a start jump used in sports. The observations also took into account factors related to the location of the operation (swimming pool, inland), the distance from the shore and the depth of immersion of the drowning person. The results show a significantly longer time for the rescuer to reach the drowning person after the rescue jump as compared to the start jump. Under standard swimming conditions, regardless of the distance and depth of immersion of the drowning person, all subjects reached the victim in the first attempt. Observations carried out in the conditions of designated inland water areas revealed comparable effectiveness in finding a simulated drowning person submerged to a depth of 2m and a significantly shorter time to reach them in favour of the start jump.

Published: July 2023

Desa Tiyinggading, Kabupaten Tabanan, Provinsi Bali merupakan desa dengan memiliki pemandangan bukit, sawah dan gunung. Hal ini menyebabkan adanya objek wisata di Desa Tiyinggading. Sebagian masyarakat Desa Tiyinggading berprofesi sebagai petani dan memelihara sapi untuk mengolah lahan pertaniannya. Salah satunya pengimplementasian perternakan didesa tersebut dengan adanya KTT Manik Amertha. Namun, kondisi lapangan pada ternak sapi KTT Manik Amertha Desa Tiyinggading masih kurang memenuhi standar. Kondisi mesin tepat guna di lahan ternak tersebut masih tidak terawat dan banyak yang rusak. Selain itu, para anggota KTT Manik Amertha belum memiliki pemahaman dan keahlian teknis yang baik sehingga kotoran sapi pun menjadi menumpuk karena tidak diolah serta hasil pupuk organik padat yang dihasilkan tidak memenuhi standar. Masalah menjadi semakin parah karena kurangnya mitra penjualan terkait dengan produk pupuk organik padat hasil olahan mitra tersebut. Dengan dilaksanakannya program pemberdayaan masyarakat ini, para mitra mengalami peningkatan pemahaman tentang proses mengolah limbah kotoran sapi menjadi pupuk organik padat, peningkatan keahlian teknis dalam mengolah pupuk organik padat serta peningkatan nilai jual pupuk organik padat.

Esta investigación se propuso promover aprendizajes y actitudes proambientales en el estudiantado de la Institución Educativa Técnica Agrícola Juan Domínguez Romero de Caracolí-Colombia, al tratar la problemática ambiental relacionada con el ecosistema asociado a una fuente de agua ubicada en el corregimiento de Caracolí, por medio de herramientas digitales durante la pandemia. Se enmarcó en un paradigma interpretativo-cualitativo, un enfoque complejo, una planificación e intervención-educativa evaluada mediante los productos de aprendizaje. Así, fue necesario replantear el rol de docentes y de estudiantes, dado que su implementación demandó cierto grado de investigación por parte del estudiantado y las estrategias desarrolladas constituyeron oportunidades de aprendizaje para estos. A partir del análisis de los productos del estudiantado, se muestran actitudes proambientales del grupo, apropiación de saberes tanto ancestrales como científicos, concienciación sobre el cuidado y uso razonable de los recursos naturales de su entorno. Se sugiere implementar el tratamiento de situaciones contextuales y la inmersión del estudiantado en procesos que los aproximen a investigar.

Eco-researchers: a proposal to promote pro-environmental attitudes and learning in elementary school
Abstract
This research aimed to promote learning and pro-environmental attitudes in the student body of the Institución Educativa Técnica Agricola Juan Dominguez Romero from Caracolí-Colombia by dealing with the environmental problem related to the associated ecosystem of a water source in Caracolí, mediated by digital tools in a pandemic. It was framed from an interpretive-qualitative paradigm, a complex approach, planning and educational-intervention evaluated through learning products. Thus, it was necessary to rethink the role of teachers and students, given that its implementation required a certain degree of research by the student body and the strategies developed constituted learning opportunities for them. From the analysis of the products of the student body, pro-environmental attitudes of the group, appropriation of both ancestral and scientific knowledge, awareness of the care and reasonable use of the natural resources of their environment are shown. It is suggested to implement the treatment of contextual situations and the immersion of the student body in processes that bring them closer to research.

Nuevos paradigmas en la gestión de esquemas de conservación en México
Authors: Álvarez-Peredo Carolina , Contreras-Hernández Armando 
Published: July 2023

Abstract
In 1997 Mexico implemented the Management Units for the Conservation and Sustainable Use of Wildlife (UMA by its initials in Spanish) scheme. However, socio-environmental problems and the lack of a multidisciplinary approach prevented it from offering sustainable solutions. Taxonomic and functional diversity in UMAs and their interactions are essential for the preservation of biodiversity and the processes that maintain their ecosystemic integrity. Ecological benefits are insufficient without a multidisciplinary vision. This article addresses a proposal for the management of UMAs and other conservation schemes with three objectives: (1) to include the “socio-ecological system” approach; (2) the recognition of their complexity; and (3) the epistemological transition from ecosystem integrity to antifragility. UMAs constitute integral socio-ecological systems that manage wildlife and habitat as a complex adaptive system precursor to ecosystem antifragility.

Resumen
En 1997 México implementó el esquema de Unidades de Manejo para la Conservación y Aprovechamiento Sustentable de la Vida Silvestre (UMA). Empero, problemáticas socioambientales y la falta de un enfoque multidisciplinario impidieron ofrecer soluciones sustentables. La diversidad taxonómica y funcional en UMA y sus interacciones son imprescindibles en la preservación de la biodiversidad y los procesos que mantienen su integridad ecosistémica. Los beneficios ecológicos resultan insuficientes sin una visión multidisciplinaria. Este artículo aborda una propuesta de gestión de UMA y otros esquemas de conservación en tres objetivos: (1) enfoque de “sistema socioecológico”, (2) reconocimiento de su complejidad, (3) transición epistemológica de integridad a antifragilidad ecosistémica. Las UMA constituyen sistemas socioecológicos integrales que manejan la vida silvestre y el hábitat como un sistema adaptativo complejo precursor de antifragilidad ecosistémica.

Purpose: Insufficient osseointegration and implant-associated infection are major factors in the failure of Ti-based implants, thus spurring scientists to develop multifunctional coatings that are better suited for clinical requirements. Here, a new biomimetic micro/nanoscale topography coating combined with antibacterial copper was simultaneously designed for Ti-based implant surfaces by adopting a hybrid approach combining plasma electrolytic oxidation and hydrothermal treatment.Results: The biological interactions between this biofunctionalized material interface and stem cells promoted cellular adhesion and spreading during initial attachment and supported cellular proliferation for favorable biocompatibility. Bone marrow mesenchymal stem cells (BMMSCs) on the coating displayed enhanced cellular mineral deposition ability, higher alkaline phosphatase activity, and upregulated expression of osteogenic-related markers without the addition of osteoinductive chemical factors, which improved osseointegration. More interestingly, this new coating reduced the viability of oral pathogens (Fusobacterium nucleatum and Porphyromonas gingivalis)—the primary causes of implant-associated infections as indicated by damage of cellular structures and decreased population. This is the first study investigating the antibacterial property of dental implants modified by a hybrid approach against oral pathogens to better mimic the oral environment.Conclusion: These findings suggest that biofunctionalization of the implant coating by surface modification methods and the incorporation of antibacterial copper (Cu) offer superior osteogenesis capability and effective antibacterial activity, respectively. These strategies have great value in orthopedic and dental implant applications.

Published: July 2023

IntroductionChronic obstructive pulmonary disease (COPD) is a complex disease involving inflammation, cell senescence, and autoimmunity. Dialectical treatment for COPD with traditional Chinese medicine (TCM) has the advantage of fewer side effects, more effective suppression of inflammation, and improved immune function. However, the biological base of TCM pattern differentiation in COPD remains unclear.MethodsLiquid Chromatography-Quadrupole-Orbitrap mass spectrometry (LC-Q-Orbitrap MS/MS) based metabolomics and lipidomics were used to analyze the serum samples from COPD patients of three TCM patterns in Lung Qi Deficiency (n=65), Lung-Kidney Qi Deficiency (n=54), Lung-Spleen Qi Deficiency (n=52), and healthy subjects (n=41). Three cross-comparisons were performed to characterize metabolic markers for different TCM patterns of COPD vs healthy subjects.ResultsWe identified 28, 8, and 16 metabolites with differential abundance between three TCM patterns of COPD vs healthy subjects, respectively, the metabolic markers included cortisol, hypoxanthine, fatty acids, alkyl-/alkenyl-substituted phosphatidylethanolamine, and phosphatidylcholine, etc. Three panels of metabolic biomarkers specific to the above three TCM patterns yielded areas under the receiver operating characteristic curve of 0.992, 0.881, and 0.928, respectively, with sensitivity of 97.1%, 88.6%, and 91.4%, respectively, and specificity of 96.4%, 81.8%, and 83.9%, respectively.DiscussionCombining metabolomics and lipidomics can more comprehensively and accurately trace metabolic markers. As a result, the differences in metabolism were proven to underlie different TCM patterns of COPD, which provided evidence to aid our understanding of the biological basis of dialectical treatment, and can also serve as biomarkers for more accurate diagnosis.

Published: July 2023

IntroductionCurrently, deep-learning-based prediction of Significant Wave Height (SWH) is mostly performed for a single location in the ocean or simply relies on a single factor (SF). Such approaches have the disadvantage of lacking spatial correlations or dynamic complexity, leading to an inevitable growth of the prediction error with time.MethodsHere, attempting a solution, we develop a Multi-Factor (MF) data-driven 2D SWH prediction model for the Bohai, Yellow, and East China Seas (BYECS). Our model is developed based on a multi-channel PredRNN algorithm that is an improved deep-learning calculation of the ConvLSTM.ResultsIn our model, the MF of historical SWH, 10 m surface winds, ocean surface currents, bathymetries, and open boundaries are used to predict 2D SWH in the next 1-72h. Our modeled SWHs show the correlation coefficients as 0.98, 0.90, and 0.87 for the next 6h, 24h, and 72h, respectively.DiscussionAccording to the ablation experiments, winds are the dominant factor in the MF model and the memory-decoupling module is the key improvement of the PredRNN compared to the ConvLSTM. Furthermore, when the historical SWH is excluded from the input, the correlation coefficients remain around 0.95 in the 1-72h prediction due to the elimination of the error accumulation. It was worse than the MF-PredRNN with the historical SWH before 10h but better than it after 10h. Overall, for the prediction of SWH in the BYECS, our MF-PredRNN-based 2D SWH prediction model significantly improves the accuracy and extends the effective prediction time length.
