Сurrent state of securing the territory of Рoltava region by points of the national geodesic network

The actual problem of securing the proper functioning of the NGN of Ukraine takinginto account regional peculiarities are studied.The analysis of the state of NGN of Ukraine on the territory of Poltava region by types ofcenters, external geodetic signals, methods of determination of coordinates is carried out in the work.The general problems of functioning of NGN in the territory of Poltava region are established.It is established that in a significant amount of points there are no external geodetic signals.The centers that fix the points of the NGN are represented by more than 40 different types. The centersdiffer in design and size. Some of them are at the same time is references of leveling II category.It is proposed to plan perspectiving measures for the modernization of the NGN on the reasonof the calculation of indicator of regional compliance of the NGN with regulatory requirements forthe density of stations to secure the implementation of topographic surveys. This indicator iscalculated as the ratio of the real amount points in the newly created administrative district to thenormative amount, and is reflected as a percentage. The normative amount is determined on the basisof the area of the respective area and the normative density of stations for the suitable scale of survey.In case of provision of stations at the level of less than 100 % it is necessary to determine theamount of points required to bring the real density in accordance with the normative. Then theexisting NGN needs modernization. Such modernization can be carried out not only in the form of renewal of existing and restoration of lost points, but also through the design and fixation ofadditional points of the calculated number.The analysis of securing of the territory of Poltava region with NGN points for implementationof topographic survey in scales 1:5000, 1:10000, 1:25000 is carried out. Specific proposals toachieve one hundred percent provision of stations in the Poltava region have been developed. Anexample of a possible realization of the respective proposals is illustrated by the design scheme ofadditional stations of the 3 class, developed on the basis of the scheme of the NGN of Ukraine.

Calculation of Transpulmonary Pressure From Regional Ventilation Displayed by Electrical Impedance Tomography in Acute Respiratory Distress Syndrome

Transpulmonary driving pressure (DPL) corresponds to the cyclical stress imposed on the lung parenchyma during tidal breathing and, therefore, can be used to assess the risk of ventilator-induced lung injury (VILI). Its measurement at the bedside requires the use of esophageal pressure (Peso), which is sometimes technically challenging. Recently, it has been demonstrated how in an animal model of ARDS, the transpulmonary pressure (PL) measured with Peso calculated with the absolute values method (PL = Paw—Peso) is equivalent to the transpulmonary pressure directly measured using pleural sensors in the central-dependent part of the lung. We hypothesized that, since the PL derived from Peso reflects the regional behavior of the lung, it could exist a relationship between regional parameters measured by electrical impedance tomography (EIT) and driving PL (DPL). Moreover, we explored if, by integrating airways pressure data and EIT data, it could be possible to estimate non-invasively DPL and consequently lung elastance (EL) and elastance-derived inspiratory PL (PI). We analyzed 59 measurements from 20 patients with ARDS. There was a significant intra-patient correlation between EIT derived regional compliance in regions of interest (ROI1) (r = 0.5, p = 0.001), ROI2 (r = −0.68, p < 0.001), and ROI3 (r = −0.4, p = 0.002), and DPL. A multiple linear regression successfully predicted DPL based on respiratory system elastance (Ers), ideal body weight (IBW), roi1%, roi2%, and roi3% (R2 = 0.84, p < 0.001). The corresponding Bland-Altmann analysis showed a bias of −1.4e-007 cmH2O and limits of agreement (LoA) of −2.4–2.4 cmH2O. EL and PI calculated using EIT showed good agreement (R2 = 0.89, p < 0.001 and R2 = 0.75, p < 0.001) with the esophageal derived correspondent variables. In conclusion, DPL has a good correlation with EIT-derived parameters in the central lung. DPL, PI, and EL can be estimated with good accuracy non-invasively combining information coming from EIT and airway pressure.

Parenchymal mechanics, gas mixing, and the slope of phase III

A model of parenchymal mechanics is revisited with the objective of investigating the differences in parenchymal microstructure that underlie the differences in regional compliance that are inferred from gas-mixing studies. The stiffness of the elastic line elements that lie along the free edges of alveoli and form the boundary of the lumen of the alveolar duct is the dominant determinant of parenchymal compliance. Differences in alveolar size cause parallel shifts of the pressure-volume curve, but have little effect on compliance. However, alveolar size also affects the relation between surface tension and pressure during the breathing cycle. Thus regional differences in alveolar size generate regional differences in surface tension, and these drive Marangoni surface flows that equilibrate surface tension between neighboring acini. Surface tension relaxation introduces phase differences in regional volume oscillations and a dependence of expired gas concentration on expired volume. A particular example of different parenchymal properties in two neighboring acini is described, and gas exchange in this model is calculated. The efficiency of mixing and slope of phase III for the model agree well with published data. This model constitutes a new hypothesis concerning the origin of phase III.

Comparative regional integration in SADC and ASEAN: Democracy and governance issues in historical and socio-economic context Integración regional comparativa de la SADC y la ASEAN: problemas de democracia y gobernabilidad en un contexto histórico y socioeconómico Analyse comparée de l'intégration régionale au sein du SADC et de l'ANASE : Enjeux démocratiques et de gouvernance établis au regard du contexte historique et socio-économique

Both the Southern African Development Community (SADC) and the Association of Southeast Asian Nations (ASEAN) support regional and national integration, the protection of human rights and civil society involvement, and non-interference in member states' internal affairs. Sometimes these goals at the regional level become mutually exclusive. Human rights groups, international organizations, and Western states have criticized human rights abuses and democracy and governance shortcomings in several ASEAN states (e.g., Vietnam and Myanmar) and SADC countries (e.g., Swaziland, Madagascar, and Zimbabwe). This article addresses ASEAN and SADC's historical context and continued development related to these issues. It also evaluates the regional organizations' effectiveness in balancing o en mutually exclusive goals and concludes that existing regional organizational strength and cohesion impact the approaches used to manage conflict and external criticism and build greater social cohesion regionally and within states. SADC utilizes a “regional compliance model“ based on political criteria whereas ASEAN utilizes a “constructive engagement“ or “economic integration first“ model. SADC places greater emphasis on placing good governance, especially as it relates to human rights, at the forefront of regionalism. ASEAN sublimates human rights to regional integration through constructive engagement and greater emphases on economic relations. Two distinct models of regional integration exist.Spanish La Comunidad de Desarrollo de África Austral (SADC por sus siglas en inglés), y la Asociación de Naciones del Sudeste Asiático (ASEAN en inglés), apoyan la integración regional/continental y nacional, la protección de los derechos humanos, la participación de la sociedad civil, y la no injerencia en los asuntos internos de los estados miembros. A veces, estas metas son mutuamente excluyentes a nivel regional. Grupos de derechos humanos, organizaciones internacionales y estados occidentales han criticado las violaciones de los derechos humanos y las deficiencias en democracia y gobernabilidad en varios Estados de la ASEAN (por ejemplo, Vietnam y Myanmar) y en algunos países de la SADC (por ejemplo, Suazilandia, Madagascar y Zimbabue). En este artículo se aborda el contexto histórico de la SADC y la ASEAN y su continuo desarrollo relacionado con los temas mencionados. También se evalúa la eficacia de las organizaciones regionales, haciendo el balance entre los objetivos a menudo mutuamente excluyentes, y concluye que la existente fuerza regional de organización y cohesión impacta los enfoques utilizados para manejar el conflicto y la crítica externa, y promueve la construcción de una mayor cohesión social regionalmente y dentro de los estados. La SADC utiliza un “modelo de cumplimiento regional“ basado en criterios políticos, mientras que la ASEAN utiliza un modelo de “compromiso constructivo“ o “integración económica primero“. La SADC pone mayor énfasis en afianzar la buena gobernanza, especialmente en lo relacionado con los derechos humanos, a la vanguardia del regionalismo. La ASEAN vincula los derechos humanos a la integración regional a través de un compromiso constructivo y pone un mayor énfasis en las relaciones económicas. Dos existentes modelos diferentes de integración regional. French La Communauté de développement d'Afrique australe (SADC en anglais), aussi bien que L'Association des nations de l'Asie du SudEst (ANASE) soutiennent respectivement les principes relatifs à l'intégration régionale et nationale, à la protection des droits de l'homme, à la participation de la société civile dans l'agenda publique, ainsi qu'à la non-ingérence dans les affaires internes des Etats. Toutefois, il arrive que ces objectifs deviennent mutuellement exclusifs au niveau régional. Les organisations de défense des droits de l'homme et les gouvernements occidentaux n'ont jamais cessé de critiquer les violations des droits de l'homme, ainsi que les lacunes en matière de démocratie et de gouvernance qui prévalent dans les pays membre de l'ANASE (ex : le Viet Nam, Myanmar) et ceux de la SADC (ex : le Swaziland, Madagascar et le Zimbabwe). Cet article aborde le contexte historique dans lequel l'ANASE et la SADC ont vu le jour ainsi que la nature des enjeux qui l'ont suivi. Il évalue également d'un point de vue comparé, l'efficacité de ces organisations régionales sur la base des objectifs qu'ils se sont fixés, tout en penchant pour la conclusion selon laquelle la présence d'une force régionale influente impacte nécessairement dans la gestion des conflits, et combien la critique externe participe à la construction d'une plus grande cohésion sociale et régionale au sein des États. La SADC s'appuie un “modèle de conformité régionale» fondé sur des critères politiques, tandis que l'ANASE fait appel à un “engagement constructif“ ayant pour modèle “l'intégration économique“. La SADC accorde davantage plus d'importance à la mise en œuvre d'une bonne gouvernance, particulièrement en ce qui concerne les droits de l'homme et l'évolution vers un régionalisme plus avancé. L'ANASE sublime les droits de l'homme à l'intégration régionale par le biais d'un engagement constructif et de grandes insistances dans les relations économiques. Ce qui fait d'eux deux modèles d'intégration régionale distincts.
