Operations for increasing the pulmonary blood flow in newborns with cyanotic congenital heart defects: results and features of outpatient postoperative monitoring
Authors: Stychynskyi O.S. , Mykhailovska A.O. 
Published: September 2024

Background. In patients with cyanotic congenital heart defects, pulmonary blood flow is maintained by a functio­ning patent ductus arteriosus (PDA). Most patients with complex ductal-dependent cyanotic defects require intermediate staged treatment before radical correction of the defect. Timely and comprehensive outpatient monitoring by a pediatrician and pediatric cardiologist are important for patient survival following palliative treatment, along with determining optimal timing for consultations at specialized cardiac surgical centers. Objective: to present the outcomes of using two methods for increasing pulmonary blood flow (systemic-to-pulmonary artery shunt (SPAS) and PDA sten­ting), as well as the features of outpatient cardiological observation and treatment in these patients. Materials and methods. From 2000 to February 2024, 22 patients underwent SPAS, and 25 — PDA stenting at the State Institution “Scientific and Practical Medical Center of Pediatric Cardiology and Cardiac Surgery” of the Ministry of Health of Ukraine. Results. After interventions, the mean arterial oxygen saturation (SatO2) increased in both groups, significantly higher in the PDA stenting group (p < 0.05). The ave­rage length of stay in the intensive care unit in the SPAS group was 19.6 ± 11.1 (range: 5 to 91) days compared to 12.8 ± 6.3 (range: 4 to 37) days in those with PDA stenting (p = 0.05). The duration of artificial lung ventilation in the SPAS group was 290.3 ± 215.3 (range: 63 to 751) hours, and in the PDA stenting group, it was shorter, 151.8 ± 75.5 (range: 39 to 549) hours (p < 0.05). Early (30-day) postoperative mortality in the SPAS group was 13.6 % (3/22 patients), with a late mortality of 18 % (4/22). In contrast, there was not early (30-day) postoperative mortality in the PDA stenting group, and late mortality was 8 % (2/25). Before the subsequent stage of surgical correction, sufficient growth of pulmonary artery branches was noted (Nakata index increased from 156.9 ± 33.3 mm2/m2 to 277.0 ± 35.9 mm2/m2 in the SPAS group and from 142.7 ± 55.2 mm2/m2 to 289.1 ± 149.2 mm2/m2 in the PDA stenting group), and the left ventricular end-diastolic index has increased (from 51.2 ± 32.4 mm2/m2 to 67.5 ± 15.5 mm2/m2 in the SPAS group and from 50.8 ± 24.9 mm2/m2 to 56.7 ± 28.5 mm2/m2 in the PDA stenting group). Thirteen patients in the SPAS group underwent the next stage of surgical correction (Glenn shunt or total repair of the congenital heart defect), while in the PDA stenting group — 17 patients. Conclusions. For cyanotic congenital heart defects, which have ductus-dependent pulmonary blood flow, both described methods are quite effective.

Settlement as a place to live is one of the main needs that need to be met for the survival of human life. The need for settlement will increase along with the increase in population. The development of settlements in Sewon District. Bantul, Indonesia which is very dynamic requires monitoring to ensure that the distribution of settlements is in accordance with the spatial pattern plan that has been determined by the local government. Imagery as a remote sensing product which is then processed with the help of GIS [HV1] can be used in monitoring the distribution of settlements because it can provide more detailed information regarding land use, including settlements. This research aims to evaluate the distribution of settlements against the detailed spatial plan (RDTR) for the Sewon Urban Area (BWP) of Bantul Regency in 2018-2038. This study uses visual interpretation techniques of SPOT-7 PMS imagery in mapping existing settlement land, field surveys, and GIS processing. The research results show that mapping settlement land using imagery produces an overall accuracy of 95.20%. The settlement evaluation shows that there is a suitability of settlement land with the detailed spatial plan reaching 579.88 hectares or 87.26%, while the settlement land that is not in accordance with the detailed spatial plan is 9.62 hectares or 1.45%, and the settlement land that is temporarily not in accordance with the detailed spatial plan is 75.05 hectares or 11.29% of the total settlement area in Sewon District. Local governments must pay more attention to existing settlements with regular monitoring so that the existing settlements that are not in accordance with the detailed spatial plan will not expand.

Published: September 2024

The Kumitir site, associated with the Majapahit Empire, is a significant archeological discovery. Archeologists from the East Java Cultural Heritage Preservation Center (BPCB), uncovered a structure at this site, buried beneath boulder-sized rocks. According to historical literature, the collapse of Majapahit was caused by volcanic eruptions from the Anjasmoro, Arjuno, or Welirang complexes. Therefore, this study aimed to recreate the gravity-driven mass flow covering the Kumitir Site. Geological surveys, including sediment structure analysis and grain orientation measurements, were conducted to provide new information on paleocurrent and ancient sedimentary processes at the site. Digital Elevation Map (DEM) and the Laharz simulation tool facilitated the creation of reconstructed lahar flow maps using open-source DEM data with an eight-meter resolution. The results of the boulder analysis showed that a paleochannel played a significant role in the burial site, with two sources identified, namely Mount Welirang (Welirang alluvial fan) and the Anjasmoro complex (Old Jatirejo alluvial fan). Meanwhile, the combination of methods applied signified the direction of the Welirang alluvial fan (ESE-NNW) and the Jatirejo Tua alluvial fan (SSW-NNE). Volumes of 9 million m3 and 65 million m3 were the most relevant parameters for estimating the lahar flows of the western and eastern craters, respectively.
CEO Pay Cuts and Investors’ Perceptions of Earnings Quality
Authors: Chou Ting-Kai , Huang Wan-Ci , Yeh Ting-Tsen , Chao Yin-Hsuan 
Published: September 2024

SYNOPSIS
The pay of a CEO is often cut in poorly performing firms to prod the CEO to work harder and restore profitability. Using earnings response coefficients (ERCs) as a proxy for investor perceptions of earnings quality, we find that ERCs decline following CEO pay cuts. Furthermore, firms with weaker oversight mechanisms and those subject to higher credibility concerns have a greater decline in ERCs following CEO pay cuts. We also offer weak evidence that credit rating agencies might perceive CEO pay cuts as impairing earnings quality. Our results suggest that pay cuts incentivize CEOs to boost earnings in the short run, and investors might perceive reported earnings as more likely to be opportunistic and of lower quality. A key implication of our study is that it provides evidence to support that the market views a CEO’s pay-cut status as vital information in appraising the earnings quality of a firm.

Authors: Souza Larissa Cristina Ribeiro e , Querino Fabiane , Calegario Cristina Lelis Leal , Alcantara Juciara Nunes de 
Published: September 2024

Purpose: In this article we investigated the effects of regulatory and normative institutional distances on Emerging Market Multinational Enterprises (EMNEs) subsidiaries performance, and the moderating roles of the ownership strategy and the government support.
Design/methodology/approach: We applied fixed-effects regression models for panel data to analyze a sample of 296 subsidiaries of 32 Brazilian EMNEs, from 2006 to 2015.
Findings: We found that institutional distance positively affects subsidiary performance. Although, full ownership, and government support positively affects subsidiary performance, subsidiaries with partial ownership located in more developed and institutionally distant host countries presents superior performance. We also found a positive relationship between government support, regulatory distance, and subsidiary performance. However, the same relationship with normative distance was not statistically relevant.
Originality/value: By analyzing different ways in which the institutional context affects subsidiary performance and different approaches to increasing or mitigating those effects, this study contributes to furthering the understanding of how institutional issues affect EMNEs, and the role of the home country government.
Conclusions: The findings of this study could help policymakers make informed decisions about investments in EMNEs. This is achieved by analyzing the impact of government financial aid on the performance of subsidiaries.

Published: September 2024

Objective –This study aims to explain the effect of fiscal decentralization and natural resources on economic growth in Indonesia; and the moderating role of corruption in both fiscal decentralization-economic growth and natural resources-economic growth nexuses.Methodology –This study uses quantitative approach by utilizing a moderated panel data regression analysis with cross-sectional observations of 34 provinces in Indonesia from 2011 to 2021.Results –Fiscal decentralization has no significant effect on economic growth, while natural resources positively affect economic growth. Furthermore, we found no moderating effect of corruption in the fiscal decentralization-economic growth nexus, but the weakening effect of corruption is evident in the natural resources-economic growth nexus. Research limitation/implications – To further encourage economic growth in the regional level, it is vital to impose budget composition requirements on regional governments in the framework of fiscal decentralization, particularly related to employee and capital expenditure; and to maintain the decentralization of natural resources management on the regional level, while continuing efforts on eradicating corruption.Novelty/Originality–Few researchers consider the role of corruption as a moderator in the relationship between fiscal decentralization and natural resources on economic growth. This study fills this gap by incorporating a moderating role of corruption that may weaken the ability of fiscal decentralization and natural resources to promote economic growth with the evidence from Indonesia’s provinces.

El dragón contra el águila. La supremacía mundial en juego
Authors: Tantaleán Adolfo 
Published: September 2024

“Cambios en la geopolítica” es una expresión que, en los últimos años, se ha convertido en moneda corriente, y no por la globalización sino por el desafío que Estados Unidos debe afrontar contra un conjunto de potencias regionales encabezadas por la República Popular China. El actual mandatario del gigante asiático está decidido a convertir a su país en la nueva superpotencia del siglo xxi. Con ese propósito, la inversión china en el mundo está en pleno crecimiento. La edificación de rutas comerciales, distintas a las usadas por Estados Unidos y sus aliados occidentales, conlleva la modernización de sus Fuerzas Armadas y el traslado permanente a distintas zonas estratégicas del mundo. Incluso, en la actual exploración espacial, China planteó el desafío más allá de lo propuesto por la desaparecida Unión Soviética: la colonización de nuestro satélite artificial. La hegemonía china tiene su talón de Aquiles en la cuestión irresuelta con Taiwán. En realidad, la soberanía de la China comunista sobre la isla cerraría el capítulo traumático de la revolución liderada por Mao Zedong. En las líneas que siguen describiremos la historia de la República Popular China y su posicionamiento en el contexto geopolítico actual.

Published: September 2024

RELEVANCE of the study lies in the assessment of the impact that various carbon regulation instruments stimulating the achievement of national climate goals have on the development scale of different electricity and heat production technologies in Russia.THE PURPOSE. To consider the change in the optimal technological structure of the electric power industry and district heating in Russia by 2050 assuming the introduction of various carbon regulation instruments in 2030.METHODS. We used the developed at ERI RAS system technological model EPOS for the optimization of the energy technology structure in the Russian energy sector according to the criterion of the minimum total discounted costs for energy supply to the economy until 2050.RESULTS. The article provides an analysis of the scale of changes in installed capacity and electricity production of various types of power plants in the UES of Russia, as well as changes in heat production of different heat supply sources by 2050 for 16 carbon regulation options and business-as-usual scenario. Also it describes the optimal technological structure in the electric power industry and district heating under the conditions of certain administrative, fiscal and economic instruments of climate policy. Carbon regulation options based on the corresponding increases in the installed capacity of power plants in the UES of Russia by 2050 are compared.CONCLUSION. Decarbonization of the electric power industry in Russia will mainly occur by expansion of nuclear energy, heat production – by deployment of electric boilers, taking into account current forecasts of scientific and technological progress. At the same time, for carbon regulation options leading to a greenhouse gas emissions reduction by 30% relative to 2019 level, nuclear power plants could become the new dominant technology in the structure of electricity production instead of gas thermal power plants. The total increase in installed capacity of power plants in the UES of Russia by 2050 may differ by almost seven times for various carbon regulation options. Among the climate policy options considered, emission quotation and carbon taxes have the strongest impact on the technological structure of the electric power industry and district heating in Russia.

Published: September 2024

RELEVANCE. Steam methane reforming is the dominant method of hydrogen production. Its significant share in global CO2 emissions highlights the importance of optimizing technological parameters to reduce environmental impact. The developed multi-component model of steam methane reforming in COMSOL Multiphysics is relevant not only due to its applicability for optimizing existing production facilities but also for its potential in developing new methods for utilizing associated petroleum gas. In the context of import substitution in the hydrogen energy sector, this model is also of interest, allowing for the calculation of technological parameters of industrial installations.THE PURPOSE. The aim of the work is to develop and verify a multi-component model of steam methane reforming.METHODS. The research methodology includes the use of experimental data from the literature and industrial indicators for integration into a multi-component model in COMSOL Multiphysics. This enables the modelling of complex chemical interactions under conditions characteristic of the industrial steam methane reforming process.RESULTS. The developed multi-component model allows calculating key parameters of the steam methane reforming process, including the concentration of components (methane, hydrogen, carbon monoxide, and carbon dioxide) and temperature along the reactor. The model successfully describes the chemical interactions between components and takes into account the influence of operating conditions, such as temperature, pressure, and steam/gas ratio, on process efficiency. The model verification was carried out by comparing the modelling results with experimental data and indicators of real industrial processes. Their correspondence confirms the high degree of reliability and suitability of the model for practical application in engineering calculations and optimization of steam methane reforming processes.CONCLUSION. The conclusions made based on the modelling can be used for further improvement of methane conversion technologies, contributing to their efficiency and environmental friendliness. There is also potential for using the model to calculate the stages of installations for the utilization of products from the processing of associated petroleum gas.
