Дослідження тенденцій розвитку промислового виробництва України в умовах зростання невизначеності середовища обумовлене необхідністю розуміння ролі галузі машинобудування, її стану у взаємозв’язку з макроекономічними факторами, що впливають на формування середовища діяльності підприємств. Інструментом, що дозволить виявляти і вивчати майбутні бізнес-умови, щоб визначати потенційні ризики і підготуватися до декількох можливих альтернатив майбутнього, пропонуємо обрати сценарний підхід.
Запропоновано визначити сценарний підхід в управлінні розвитком машинобудівних підприємств як превентивний метод, використання якого надає можливість виявити ключові невизначеності бізнес-середовища, різні наслідки яких формують альтернативні сценарії його майбутнього розвитку, і дозволяє співвідносити ймовірні результати діяльності машинобудівних підприємств із ужитими в даний момент діями, прорахувати потенційні ризики та адаптувати їхні прояви до цільових настанов підприємства. Обґрунтовано актуальність застосування сценарного підходу в дослідженні бізнес-середовища для машинобудівної галузі та визначено етапи організації розроблення сценаріїв бізнес-середовища машинобудівних підприємств.
За проведеним дослідженням стану машинобудівних підприємств визначено складові зовнішнього середовища машинобудівних підприємств, що впливають на ефективність їхнього розвитку, комбінації яких покладено у формування сценарної матриці для відображення сценаріїв середовища майбутнього.
На основі застосування сценарного підходу до вибору стратегії розвитку машинобудівних підприємств запропоновано варіанти сценаріїв, що укладаються у варіабельності напрямів розвитку середовища функціонування. Вибір стратегій розвитку машинобудівних підприємств заснований на урахуванні стратегічних цілей на базі побудови матриць ефектів, збитку й ризику. Знаходження максимального математичного очікування цільової функції й мінімального математичного очікування ризику дозволить ефективно реалізувати методику вибору варіанта цілі.

The article analyzes the concepts to determine the essence of the investment project. The theoretical and methodical approach to the definition of an investment project, which will provide the possibility for a clear identification of the essential features, ensure an effective interaction with internal and external dynamic environment is offered. The most common classification features of investment projects are singled out. The main features of the definition of the functions of investment management as a management system and a special area of enterprise management are determined.
It was emphasized that for the steady positive development of industrial enterprises in a competitive and rapidly changing environment, effective management of investment activity of enterprises is a necessary condition for functioning. In addition, it is proved that in the context of the limited financial and other types of resources, the use of an integrated approach to investing is one more major area for improving the efficiency of management of investment processes at the macro level, and an integrated investment design is a system-integrated process of management of a set of investment projects that are subordinated to a single strategic plan focused on the successful implementation of the enterprise investment program. The necessity of further, more profound research of investment management in conditions of uncertainty and risk is substantiated. The next stage of the research should be the construction of a system for making investment decisions in conditions of uncertainty and risk.

Обґрунтовано передумови та доречність презентації, окрім фінансової екологічну, соціальну та управлінську інформацію широкому колу користувачів, у тому числі, інституційним інвесторам, у форматі ESG-звітності з метою створення довгострокової цінності бізнесу на принципах прозорості та ділової етики із урахуванням важливих критеріїв, які мають ураховувати підприємства, що розраховують на інвестиції та стійку позицію на ринку. Доведено, що суб’єкти бізнесу, які орієнтуються на такий формат звітності, керуються філософією сучасного ефективного бізнесового мислення відповідно до нової парадигми — концепції сталого розвитку.
Проаналізовано науково-методичні напрацювання з питань оприлюднення та звітності широкого спектра фінансових і нефінансових показників, що дають можливість імплементувати важливі елементи та об’єкти в облікову систему з метою складання інтегрованої звітності, на основі чого виокремлено основні критерії, які мають ураховувати підприємства, що розраховують на інвестиції та стійку позицію на ринку, що в комплексі дає можливість формувати стійке уявлення про реальний стан бізнесу.
Обґрунтовано контент ESG-звітності, що базується на особливих принципах і методології у контексті «триєдиного підходу» — ефективної синергії економічної, екологічної та соціальної складових. Доведено раціональність такого підходу як системного, оскільки на його підставі, по-перше, можна забезпечити обґрунтованість виділення об’єктів, суб’єктів обліку та, по-друге, дослідити взаємозв’язок між ними, максимально врахувавши вплив достатньо великого спектра чинників і захистити в такий спосіб «право облікової системи» на самовдосконалення та динамічний розвиток у зв’язку із збільшенням інформаційних запитів користувачів у системі сталого розвитку.

O poder de narrar: geopolítica da distribuição cinematográfica no Brasil
Authors: Rogowski Pozzo Renata 
Published: August 2020

RESUMO O presente ensaio desenvolve uma investigação dentro do campo da economia política da cultura que objetiva problematizar e desvendar caminhos para o entendimento do quadro de hegemonia do cinema hollywoodiano no Brasil, tendo como foco a distribuição em salas. Coloca-se como hipótese que o subdesenvolvimento econômico do cinema nacional tem origem em questões de ordem macroeconômica, a saber, na estrutura oligopolista da indústria cinematográfica em escala mundial que logrou a dominação do mercado, especialmente da esfera da distribuição, pelas majors. À luz do que escreve Ellen Wood sobre o imperialismo contemporâneo, opera-se com as ideias de tríade competitiva de Alfred Chandler, centralização do capital de Harry Braverman e mundialização do capital de François Chesnais, para entender a estrutura e a organização contemporânea das grandes corporações de mídia. A partir de dados publicados pelo Observatório Brasileiro do Cinema e do Audiovisual (OCA-ANCINE), analisa-se a atuação das distribuidoras estrangeiras no Brasil, bem como dois movimentos contemporâneos que reconfiguram o mercado: a digitalização das salas e a emergência do streaming.

Interferências culturais: @ pesquisador@ integral na vacuidade amorosa
Authors: Gauthier Jacques 
Published: August 2020

A partir dos conceitos de vigilância amorosa e de vacuidade amorosa procuramos orientações éticas e epistemológicas para pesquisas interculturais. O símbolo dá acesso aos aspectos luar e cruel do conhecimento, ignorados pela ciência eurodescendente, mas presentes nas epistemologias afrodescendente e indígenas, na forma de Oxum e da Onça. Daí a ampliação da epistemologia solar eurodescendente para conexões energéticas indígenas e africanas, rumo à formação d@ pesquisador@ integral, que integra o Cruel e o Carinhoso num pensar com o coração. Podem ser desenvolvidas ciências interculturais a partir dos enraizamentos filosóficos de cada povo. Após Bergson erigindo a intuição em método entramos no transe como método, principalmente em referência ao contato budista com a vacuidade e à prática de dispositivos dançantes. Assim se cria a transculturalidade pela extinção do Ego, inclusive, acadêmico - e pela entrada na quinta dimensão do saber.Palavras-chave: Transculturalidade. Sociopoética. Epistemologia.
Comparative Evaluation of Bismuth-Silver and Bismuth-Tin Alloys for Plug and Abandonment

Published: August 2020

Summary
As an alternative to cement, the feasibility of bismuth-tin (BiSn; contains 58 wt% Bi and 42 wt% Sn, abbreviations are not in stoichiometric ratio) as a low melting-point plug has been tested by Zhang et al. (2020) for rigless plug-and-abandonment (P&A) service of offshore wells. Similar to BiSn, bismuth-silver (BiAg; contains 97.5 wt% Bi and 2.5 wt% Ag, abbreviations are not in stoichiometric ratio) also exhibits desirable properties compared with Portland cement. However, because of its greater melting point, BiAg has potentially a wider application than BiSn, especially in deep formations. In the present study, we investigate the feasibility of BiAg alloy for P&A. The bond quality of the alloy-shale cores is evaluated through shear, tensile, push-out, and permeability tests, and compared with those of BiSn alloy-shale and cement-shale cores. To avoid phase change-induced shale damage at elevated temperature while setting BiAg plugs, water was first extracted with supercritical carbon dioxide (CO2). For shear and tensile tests with pinhole-anchored BiAg, the ultimate strength and modulus were measured as a function of anchor points at different temperatures (21, 80, and 110°C). For the push-out tests, shale samples of smooth, rough, and pinholed surfaces were prepared with the BiAg alloy plug. In general, we find that, without anchors, bond failure precedes shale failure. Results for cement-shale cores are also reported for comparison. We contrast the performance of BiAg and BiSn alloys at 21, 65, 80, and 110°C to determine the crossover temperature for deployment suitability.

Published: August 2020

Summary
A model for gas transport in nanoscale channels in shale-gas reservoirs (SGRs) is proposed using a new effective mean free path (MFP) model, which considers the effects of surface/gas interaction and the geometrical termination of a nanochannel boundary. In addition, the influences of the nanochannel dimension, formation-burial depth, surface type, and gas type on nanoconfined gas flow in slit channels are addressed. The nanoconfined gas-flow behavior is investigated for a wide range of temperature and pressure in this work because of the large prospects of shale gas in deep and ultradeep formations with pressure up to 100 MPa and temperature up to 480 K. The newly developed effective MFP model and the gas-flow-rate model are successfully validated with data from molecular dynamics (MD) simulations and experiments. Results show that the effect of surface force reduces the MFP and gas-flow capacity, which increases with a decreasing pressure, a decreasing channel size, and an increasing temperature; that the nanoconfinement effect has weaker influence on gas-transport capacity as the formation-burial depth increases and greater influence as formation pressure decreases during hydrocarbon production from SGRs; that a surface type affects the gas transport, and the gas-flow capacity in carbon (C) channels (organic channels) is stronger than that in silicon (Si) channels (inorganic channels) with the same size; and that the differences among the transport capacities of nitrogen (N2), argon (Ar), and methane (CH4) are not obvious, while the transport capacities of helium (He) are greatly lower compared with CH4 at both the SGR temperature and the laboratory temperature.

Abstract
Background: Empirical evidence that demonstrates the relationship between pelvic asymmetry and non-specific chronic low back pain (NCLBP) is currently lacking. Objective: To establish the reliability of the Global Postural System (GPS) in assessing pelvic asymmetry and identify the association between pelvic asymmetry parameters and the occurrence of NCLBP in young adults.Design: A cross-sectional, regression study. Methods: People who were aged between 18 and 30 and were diagnosed with NCLBP were recruited. Healthy individuals who were matched for age, sex, and education level were recruited as controls. Global Postural System (GPS) was employed to assess pelvic asymmetry. Prior to exploring the association, the reliability of GPS was assessed by the ICC (2, k) for interrater reliability, ICC (3, k) for intra-rater reliability, standard error and minimal detectable difference. Bivariate correlation analysis and logistic regression analysis were used to determine the relationship between pelvic asymmetry and the occurrence of NCLBP.Results: Twenty-eight healthy participants and 28 people with NCLBP were recruited. Moderate to excellent ICCs were observed for the inter-rater and intra-rater reliability of most postural parameters. The bivariate correlation analysis indicated that age, body mass index and pelvic asymmetry parameters were related to the occurrence of NCLBP. Pelvic angle asymmetry (odds ratio=1.17), and asymmetry of the distance between the posterior superior iliac spine and the floor (odds ratio=1.21) were associated with NCLBP.Limitation: This study did not explore the causal relationship between pelvic asymmetry in the sagittal plane/pelvic asymmetry in the transverse plane and the occurrence of NCLBP. The interpretation of the results may not be generalized beyond the sample population.Conclusions: The GPS is a reliable method to assess pelvic asymmetry in a clinical setting. Two pelvic parameters were associated with the presence of NLBP. Measurement of pelvic asymmetry may assist in the early identification of potential occurrence of NCLBP but further work is required.

Abstract
The magnetotelluric method is increasingly being used to monitor electrical resistivity changes in the subsurface. One of the preferred parameters derived from the surface impedance is the strike direction, which is very sensitive to changes in the direction of the subsurface electrical current flow. The preferred method for estimating the strike changes is that provided by the phase tensor because it is immune to galvanic distortions. However, it is also a fact that the associated analytic formula is unstable for noisy data, something that limits its applicability for monitoring purposes, because in general this involves comparison of two or more very similar data sets. On the other hand, the classical Swift’s approach for strike is very stable for noisy data but it is severely affected by galvanic distortions. In this paper we impose the criterion of Swift’s approach to the phase tensor. Rather than developing an analytical formula we optimize numerically the same criterion. This stabilizes the estimation of strike by relaxing an exact condition to an optimal condition in the presence of noise. This has the added benefit that it can be applied to windows of several periods, thus providing tradeoffs between variance and resolution. The performance of the proposed approach is illustrated by its application to synthetic data and to real data from a monitoring array in the Cerro Prieto geothermal field, México.

Published: August 2020

Abstract
Background: Based on the previous investigation in our institution, the incidence of intraoperative hypothermia in neonates was high. Since September 1st, 2019, the recommendation had been launched to utilize ≤1 L/min fresh gas flow during the neonates’ surgical procedure. We therefore intended to evaluate the association between low fresh gas flow anesthesia and the occurrence of hypothermia in neonates undergoing digestive surgeries. Methods: A retrospective chart review, before-after study was conducted for neonates who underwent digestive surgeries. The primary outcomes were the incidence of hypothermia. The secondary outcomes included hospital mortality, the value of lowest temperature, blood loss, mean body temperature during the surgery, the length of hypothermia during the surgery and postoperative hospital length-of- stay (PLOS). Results: 249 neonates fulfilled the eligibility criteria. The overall incidence of intraoperative hypothermia was 81.9%. The low fresh gas flow anesthesia significantly reduced the odds of hypothermia [routine group: 149 (87.6%) versus low flow group: 55 (69.6%); p ＜ 0.01]. Moreover, the low fresh gas flow anesthesia could reduce the length of hypothermia [routine group: 104 mins (50, 156) versus low flow group: 30 mins (0,100); p ＜ 0.01], as well as elevate the value of lowest temperature for neonates [routine group: 35.1℃ (34.5, 35.7) versus low flow group: 35.7℃ (35.3, 36); p ＜ 0.01]. After adjustment for confounding, low fresh gas flow anesthesia and the length of surgical time were independently associated with intraoperative hypothermia.Conclusions: Low fresh gas flow anesthesia is an effective way to alleviate hypothermia in neonates undergoing open digestive surgery.
RBE-weighted dose conversions for patients with recurrent nasopharyngeal carcinoma receiving carbon-ion radiotherapy from the local effect model to the microdosimetric kinetic model

Published: August 2020

Abstract
Background

We sought to establish a conversion curve to convert the RBE-weighted doses calculated by local effect model I (LEM) (LEM RBE-weighted doses) in patients with locally recurrent nasopharyngeal carcinoma (rNPC) to the RBE-weighted doses calculated by microdosimetric kinetic model (MKM) (MKM RBE-weighted doses). We also converted the LEM dose constraints (RBE-weighted dose constraints in LEM plans) for the brain stem, spinal cord, and optic nerve based on this curve.

Methods

Data from 20 patients with rNPC receiving carbon-ion radiotherapy (CIRT) in our hospital were collected. LEM in Raystation (V8A, Raystation, Sweden) was used to generate treatment plans. The clinical target volume CTV1（GTV+5mm）was given 3 Gy (RBE) per fraction. Ninety-nine percent of target volumes should be covered by 95% of the prescriptions; the maximum doses of the brainstem and spinal cord were < 45 Gy (RBE) and < 30 Gy (RBE), respectively. The doses covering 20% volumes of optical nerves/chiasms D20 were < 30 Gy (RBE). Then physical doses of the LEM plans were recalculated by using MKM in Raystation to generate MKM plans. A series of conversion factors (i.e., the ratio of LEM RBE-weighted dose to MKM RBE-weighted dose) was then obtained by using an isovolumetric dose method. The LEM plan prescriptions (LEM prescription) and dose constraints of the organs at risk (OARs) (OAR constraints) were converted to the corresponding MKM prescriptions and dose constraints using this conversion curve.

Results

For the CTV1 fractional RBE-weighted dose prescription of 3.00 Gy (RBE) and CTV2 of 2.70 Gy (RBE) in LEM plans, the conversion factors (LEM RBE-weighted dose/MKM RBE-weighted dose) were 1.37 (CI 95％ 1.35–1.39) and 1.46 (1.41–1.51), respectively. The average conversion factors from 1.37(CI 95％ 1.33–1.41) to 3.09 (2.94–3.24) corresponded to the LEM fractionated doses from 2.86 Gy (RBE) to 0.24 Gy (RBE), including the doses constraining upon OARs. LEM RBE-weighted doses of 30 Gy (RBE) and 45 Gy (RBE) in 21 fractions were converted to MKM RBE-weighted doses of 16.64 Gy (RBE) and 30.72 Gy (RBE) in 16 fractions.

Conclusions

This conversion curve could be used to convert LEM RBE-weighted doses to MKM RBE-weighted doses for patients with rNPC receiving CIRT, providing dose references for re-irradiation therapy.
