Authors: Montenegro Salamone Nunes Danielle , Ribeiro de Medeiros Otávio
Published: November 2022

No contexto da crise financeira originada no mercado imobiliário norte-americano no final de 2007, a incerteza em relação às políticas que seriam adotadas chamou atenção da área acadêmica e provocou uma série de questionamentos a respeito de seus efeitos no mercado de capitais. Este artigo analisa o impacto da incerteza política no mercado de capitais em nove países. Foram submetidos a um estudo empírico dados mensais de Estados Unidos, Canadá, Reino Unido, Alemanha, Espanha, Itália, França, Índia e China de janeiro de 2003 a dezembro de 2013. Os resultados das regressões indicam que a incerteza política aumenta a volatilidade dos retornos e que o mercado exige um prêmio de risco pela incerteza política, sendo a associação entre essas variáveis maior em situações econômicas adversas. Os resultados demonstram ainda que houve um aumento no nível de incerteza política dos países analisados após a referida crise financeira. Percebe-se, conforme esperado, que a incerteza política impacta os mercados de capitais dos países analisados.

Medical Research in the 1950s in the Medical Journal of the ROK Army: Focusing on Research on Infectious Diseases
Authors:   The Korean Association for the Social History of Medicine, Shin Miyoung
Published: November 2022

This paper attempts to understand the characteristics of infectious disease research conducted in Korea in the 1950s by analyzing the papers published in the Medical Journal of the ROK Army. It is explained that Korea in the 1950s lacked many things due to the influence of the war. During this period, Korean medicine was depicted as laying the foundation for development by learning American medicine with the aid of the international community. Meanwhile, as medical personnel were concentrated in the military from the beginning of the war, medical research activities were conducted around the military. It can be said that Korean medicine in the 1950s did not exist only passively. At that time, the representative military medical journal, the Medical Journal of the ROK Army, provided space for academic activities where researchers published their studies on various topics. This paper finds the following characteristic features by focusing on the infectious disease theses published in the Medical Journal of the ROK Army. First, researchers were more interested in tuberculosis or parasite-related diseases than in acute infectious diseases. Even if the research on chronic infectious diseases did not use the latest research method, many papers had been published because it was relatively easy to access the topic through group examinations or statistical observation research. Second, the journal served as space for fostering emerging medical personnel. Researchers from medical schools mobilized for the military at the beginning of the war earned their degrees by publishing papers in the journal. Since then, they had contributed greatly to academic development by working at universities or research institutes. Third, as time passed, the identity as a military medical journal was established for the Medical Journal of the ROK Army. While there were many infectious disease studies targeting the general public at the early stages of the journal’s publication, more studies came to target the military group in the latter half of the 1950s. Representative examples include a paper in which the Army Headquarters Medical Office published knowledge on infectious diseases necessary to manage the military and a study on mosquitoes in relation to the areas where military units were located. Judging from the papers on infectious diseases published in the Medical Journal of the ROK Army, Korean medicine in the 1950s conducted independent research, albeit weak, which had an impact on the development of medical and health care afterwards.

Tanulmányunkban amellett érvelünk, hogy amikor a fogyatékossággal élő emberek helyzetét, jóllétét szeretnénk értékelni, akkor a társadalmi környezetet és az egészségügyi szempontokat egyszerre, együttesen kell megragadni. Ezt az állításunkat egy hallássérültekkel és környezetükkel végzett részvételi akciókutatás első, megalapozó szakaszának eredményeivel támasztjuk alá. Az érintett közösség helyzetének feltárásához kvalitatív módszereket használunk, az értékelés alapját pedig az Amartya Sen nevéhez fűződő képességszemlélet adja. Úgy gondoljuk, a képességszemlélet alternatívája lehet egy hagyományos szakpolitikai megközelítésnek, és segíthet mélyebben megérteni az érintettek helyzetét és ezáltal meghatározni a megfelelő segítés módjait. A tanulmány újdonságát két dologban látjuk. Egyrészt újdonságértékű a hallássérült (siket és nagyothalló) emberekkel és környezetükkel végzett kvalitatív kutatás gyakorlati tapasztalatainak beágyazása egy részvételi akciókutatásba, másrészt eddig nem jelent meg a hazai szakirodalomban a képességszemlélet és a fogyatékosságtudomány összekapcsolása. Tanulmányunkat egyaránt szánjuk a fogyatékossággal élő emberek, különösen a hallássérültek környezetében élő segítőknek, részvételi kutatásokban jártas társadalomkutatóknak, és a fogyatékossággal foglalkozó szakpolitika döntéshozóinak.

One of the concrete technologies developed to obtain good compressive strength of concrete is additional material for iron lathe waste obtained from the residue of the iron turning process. This study aims to determine the effect of iron lathe waste as a fine aggregate additive on the compressive strength of concrete. The compressive strength test of concrete was carried out based on The SNI standard 1974:2011. The sample making of the specimens was carried out by varying 0%, 1.5% and 2.5% of iron lathe waste from the weight of fine aggregate in a concrete mixture with a concrete compressive strength of 29.05 MPa. Concrete samples were tested at the age of 7 days, 14 days, and 21 days. The test results show that the maximum compressive strength of concrete is achieved by normal concrete (0%) which is 28.96 MPa at the age of 21 days of concrete. While the value of the compressive strength of concrete after being given a mixture of iron lathe waste decreased. The optimum concrete compressive strength with the addition of iron lathe waste was obtained at 24.63 MPa with a mixture of 1.5% at the age of 21 days of concrete. The decrease in the compressive strength of concrete due to the addition of iron lathe waste. It occurs because of the air trapped in the concrete, causing the concrete to be hollow and not solid, so that the compressive strength of the concrete decreases.

Mortar is an especially important component used for construction. The building blocks of mortar consist of cement, fine aggregate, and water. In this study, oyster shells were used as a substitute for fine aggregate due to the increasing production of oyster shells every year, with the hope that the use of oyster shells could reduce oyster shells waste in the environment and obtain innovations for the construction world. The test objects were made in the form of a cube using a mixture ratio of 1 PC: 3 PS with variations of 0%, 5%, 10%, and 15% of shells against the weight of sand with a test time of 3 days, 14 days, and 28 days. Before making the test object, the mortar constituent materials were tested first, then the mortar design was carried out after all the constituent materials met the requirements. This study also used SPSS software to determine the effect of using shells as a substitute for fine aggregate on the compressive strength of mortar. From this study, it was found that the effect of oyster shells substitution was 17.6% at the age of 28 days compared to mortar without shells. The use of oyster shells can increase the compressive strength of mortar up to 97.6% at the age of 28 days. A variation of 15% was found at the age of 28 days as a variation with a maximum compressive strength value of 18.06 MPa.

A New Route Choice Model for Urban Public Transit with Headway-based Service
Authors: Horbachov Peter , Makarichev Oleksandr , Svichynska Olha
Published: November 2022

A new approach to create the model of individual behavior in urban public transit systems with headway-based service that is built on the same principles of rational decision making as discrete choice models is presented. To describe a passenger's decision-making, the attractiveness function which reflects the difference between trip results and costs was used. The attractiveness of the transit route was determined by solving the system of Fredholm's integral equations based on observed frequencies of choosing the alternative routes by each individual. The frequencies were determined based on multi-day survey results and range between 0 and 1 but equal neither 0 nor 1. To estimate the significance level of the attractiveness function, the regression analysis was used and the accuracy of the choice probability forecast was evaluated. Computation of model coefficients was carried out based on the parameters of home-based work trips obtained via the travel survey that was conducted in the city of Kharkiv, Ukraine.

Published: November 2022

The protective effect of medroxyprogesterone acetate on propionic acid-induced autism in rats was evaluated. For this purpose, 30 rats were divided into three groups. The significant difference in the levels of IL-17 (p<0.05), IL-2 (p<0.05), and TNF-α (p<0.05), lactate (p<0.05), and nerve growth factor (p<0.05) were found in the medroxyprogesterone-treated group by biochemical analysis. In histopathological examination, the medroxyprogesterone-treated group revealed significant improvement in neural body degeneration, neural count, and dysmorphological changes in both CA1 and CA3 regions. Immunohistochemical examination revealed improvement in glial activity with glial fibrillar acidic protein and morphological changes in Purkinje cells. Magnetic resonance spectroscopy showed an improvement in the level of lactate duplets in the medroxyprogesterone-treated group. To our knowledge, this is the first study, to evaluate the protective effect of medroxyprogesterone on propionic acid-induced autism in rats.

Published: November 2022

This work intended to investigate potential correlations between past experienced personal trauma to the everyday experience of workplace well-being. The authors explored traumatic childhood stories using the Philadelphia extended version of the original Adverse Childhood Experiences (ACEs) survey. Connections to these experiences were sought in a broad range of populations using snowball sampling. Participants (N = 406) were asked to answer the ACEs survey and questions on their current perception of workplace well-being using the Eudaimonic Workplace Well-Being Scale (EWWS). Results indicated a strong correlation that was statistically significant. An increase in the number of ACEs aligned with a lower perception of well-being within the workplace. This is the first study of its kind to connect clinical childhood trauma  experience with current adult workplace experience of well-being. Findings suggest enhanced focus should be placed on engaged awareness and action-oriented treatment of mental health in the workplace.

Digital information models as geospatial research tools
Authors:   JSC «Uralgeoinform», Anashkin P. A.
Published: November 2022

The list of sectors of the economy that need digital geoinformation support for territories is growing dynamically. The conceptual and semantic apparatus of digital modeling of objects is developing no less dynamically, which often duplicates the essence of the terms used in geodesy and cartography, but uses other, sometimes contradictory, formulations. The problems of discrepancies in names, for-mats and the lack of well-established transformation algorithms do not allow achieving the maximum synergistic effect in information modeling technology and in practical economic activity. This work is devoted to identifying and systematizing problems based on an analysis of the current regulatory legal acts and trends in digital information modeling. The approaches to digital information modeling of ob-jects at the micro and macro levels are compared. The possibility of creating new knowledge, not amenable to algorithmization, based on associative perception of a three-dimensional visual image of a model, is considered. Discrepancies of essentially identical terms in the conceptual and semantic appa-ratus of modeling at the micro and macro levels are presented. The necessity of synchronization of definitions and composition of terms has been established. A mechanism for the formation of a classi-fier of attributes of a micro-level model based on well-established and debugged terms of a developed set of classifiers used in macro-level models is proposed. Using a specific example of urban environ-ment modeling (CIM), the role of the macro-level model as a consolidating basis for the interoperable integration of heterogeneous micro-level models is substantiated. The problem of developing an opti-mal algorithm for converting normative formats of data representation of micro-level models into for-mats of macro-level models and vice versa is formulated. Consolidation of BIM and GIS community resources is proposed for the purposeful development of information modeling technologies.
Application of terrestrial laser scanning technology for creating record drawings of building facades
Authors:   Siberian State University of Geosystems and Technologies, Altyntsev M. A.
Published: November 2022

The technology of terrestrial laser scanning allows solving a large range of measurement tasks, among which the creation of record drawings for building facades can be distinguished separately. The main advantage of laser scanning over other surveying methods is the high speed of data acquisition and their density, which allows displaying even small parts of the facade in the drawing. To reliably deter-mine the details of which size can be identified from laser scanning data, and what maximum scale of the drawing can eventually be created, it is necessary to conduct studies of the accuracy and detail of the data of each laser scanner planned for use. The data of the Leica ScanStation 2 and Geomax Zoom 300 were analyzed. As a result of analysis, it was found that the divergence of Zoom 300 laser beam exceeds the value stated in the technical characteristics. It is shown that the scanner ScanStation 2 al-lows creating measuring drawings up to the scale of 1:50, and Zoom 300 – up to 1:200. To achieve the accuracy of creating a 1:200 scale drawing using the Zoom 300 scanner, a number of recommenda-tions for placing scanner positions and processing the obtained point cloud to remove measurements made with lower accuracy are offered.

In the mining areas of the Tula region there are more than 130 technogenic mineral formations formed as a result of the extraction, processing and using of minerals. Monitoring of lands around technogenic mineral formations is an important task and it should be solved with the application of advanced tech-nologies. We propose the scheme for averaged zoning of the negative impact on the surrounding lands of technogenic mineral formations on account of water and wind erosion of TMT rocks, TMT defor-mations, water filtration through the TMT body into aquifers. The possibilities of the online service "Public Cadastral Map" for monitoring lands around technogenic mineral formations are considered. Waste heaps of mines No. 27 Lesnaya (Mostovaya) and Zapadno-Shchekinskaya 17-bis were taken as an example for monitoring all registered land plots was carried out, located in each zone of influence. The monitoring showed that when identifying the negative impact of technogenic mineral formations on the surrounding lands, it is important to pay attention to the shape and size of TMT, areas of land plots, land categories, the percentage of accounted lands around TMT.

Land resources are the main means of agricultural production and the spatial basis for all types of objects. The Russian Federation has huge reserves of natural resources, including agricultural land, which in some regions are used irrationally. Not only the well-being of Russians, but also the food security depends on the careful attitude to the lands of this category. Statistical data on the availability of lands of the first category are given and the issues of increasing the level of use of these lands are considered. The role of the Unified State Register of Real Estate, ensuring the safety of agricultural land, is shown. The main reasons are reflected, as a result of which the lands intended for growing crops are unclaimed. Possible ways to reduce unused lands of this category are proposed. Recommendations for reducing the area of unused land by selling them at auctions are given.

Published: November 2022

The implementation of the concept of integrated development of the scientific and technical project "Digital Railway" provides for the development of digital technologies in all areas of activity of JSC "Russian Railways", including the track economy. In order to monitor the current state of the tracks, digital models of the tracks are created and maintained at the level of modern requirements, used to collect, store and evaluate spatial data on the current state of the tracks and develop recommendations for the prevention and elimination of identified malfunctions. The most effective and universal means of controlling and straightening the track is the coordinate method based on a system of continuous coordinate-digital description of the track in a single coordinate system. Track measuring wagons widely used in the railway network do not allow obtaining the geometric parameters of the track in a single coordinate system. Because of this, in our country and in foreign countries, various track-measuring systems have been developed and are used, allowing to obtain the CMR in coordinates. Therefore, the purpose of theoretical and experimental research is to identify the accuracy of determining the geometric parameters of the railway track using the Gedo track measuring trolley. The method of determining the track geometry, technical characteristics and distinctive features of the Gedo track measuring trolley are considered. A program of experimental studies is described and comparative accuracy estimates of the railway track geometry determination by the geodetic method, using a Gedo track measuring trolley and a rail gauge template are given. It is shown that in connection with the transition of the railway industry to digital technologies for modeling infrastructure facilities, it is most expedient to use the Gedo track measuring trolley for monitoring the geometry of the railway track, which provide the required accuracy of determining the geometry of the track, productivity and obtaining the necessary information in a single coordinate system.

Integration of mobile laser scanning and aerial imagery data for generating digital surface models
Authors:   Siberian State University of Geosystems and Technologies, Altyntsev M. A.
Published: November 2022

Aerial photography and mobile laser scanning are some of the most efficient methods of surveying, which allow creating digital surface models of the area with high accuracy and detail. Both of these methods allow gathering information about the area in the form of point clouds. However, due to the fact that the aerial survey data are obtained from the air, and the MLS ones from the ground, point clouds obtained by different methods display the same territory with different detail. For example, the roofs of buildings are well recognized from aerial data, and their walls – from MLS ones. The necessity of combined use of heterogeneous data through their integration is appeared. In this case, it is necessary to solve a number of tasks, such as registration of point clouds, assessing visibility zones depending on the survey territory, saving in the final combined point cloud only those points in the over-lapping areas that most accurately and fully describe the shapes of the terrain objects, filtering false measurements. The main tasks that arise during data integration are discussed. The technique of integrating mobile laser scanning and aerial photography data for generating a single digital surface model is proposed. This technique consists in recognizing the separated objects of the territory or their parts. The study results of the developed technique based on the data of Novosibirsk are presented.

Establishment and application of loop-mediated isothermal amplification coupled with nanoparticle-based lateral flow biosensor (LAMP-LFB) for visual and rapid diagnosis of Candida albicans in clinical samples
Authors: Wang Yu , Zhao Xue , Zhou Yuhong , Lu Jingrun , Yu Honglan , Li Shijun
Published: November 2022

Candida albicans is an opportunistic pathogenic yeast that predominantly causes invasive candidiasis. Conventional methods for detecting Candida species are costly, take 3–5 days, and require skilled technicians. Rapid pathogen identification is important in managing invasive candidiasis infection. Here, a novel molecular diagnostic assay termed loop-mediated isothermal amplification combined with nanoparticles-based lateral flow biosensor (LAMP-LFB) was developed for C. albicans rapid detection. A set of six primers was designed based on the C. albicans species-specific internal transcribed spacer 2 (ITS2) gene. The C. albicans-LAMP results were visually reported by LFB within 2 min. Various fungal strains representing Candida species, as well as several Gram-negative and Gram-positive bacterial species, were used to determine the analytical sensitivity and specificity of the assay. The optimal LAMP conditions were 64 °C for 40 min, with a sensitivity of 1 fg of genomic DNA template from C. albicans pure cultures. No cross-reactions were obtained with non-albicans strains. Thus, the analytical specificity of the LAMP-LFB assay was 100%. The entire procedure could be completed within 85 min, including specimen processing (40 min), isothermal reaction (40 min), and result reporting (within 2 min). In 330 clinical samples (including 30 whole blood, 100 middle segment urine, and 200 sputum samples), all C. albicans-positive (62/330) samples were identified by LAMP-LFB assay, and the diagnostic accuracy was 100% when compared to the traditional clinical cultural-based methods. Thus, this assay can be used as a diagnostic tool for the rapid, accurate, sensitive, low-cost and specific detection of C. albicans strains, especially in resource-limited settings.

Background: To evaluate prognostic value of WTAP levels in tumor and paired adjacent non-neoplastic liver tissues (PANLT) for cases of hepatitis B virus (HBV)-positive Asian small hepatocellular carcinoma (sHCC) patients who received curative partial hepatectomy.

Method: The investigation with two external cohorts were included. Associations between hazard risk of recurrence and continuous WTAP levels were investigated with restricted cubic spline models. Cox and inverse probability weighting models were established for survival analysis. Based on interaction effects, further stratification analysis was performed. Landmark analysis was employed to analyze cases of late recurrence. Finally, sensitivity analysis was performed to assess unmeasured confounders.

Findings: In an investigation cohort of 307 patients, restricted cubic spline models indicated that hazard risk of recurrence increases with elevated WTAP levels for sHCC and PANLT. However, using Cox and inverse probability weighting models, no significant differences were observed in recurrence-free survival (RFS) between groups with different WTAP levels in sHCC. Multivariate analysis showed that patients with high PANLT WTAP levels had significantly worse RFS (HR 1.567, 95% CI 1.065–2.307; p = 0.023). Based on the significant interaction effect between WTAP levels in sHCC and PANLT, stratification analysis revealed that recurrence risk is more pronounced in patients with high WTAP levels in both PANLT and sHCC. Landmark analysis showed that late recurrence was more likely to occur in patients with high PANLT WTAP levels (HR 2.058, 95% CI 1.113–3.805; p = 0.021). Moreover, the detrimental effects of elevated PANLT WTAP levels on RFS were validated with two external cohorts. Sensitivity analysis confirmed the robustness of results.

Conclusion: Increased PANLT WTAP expression levels independently predict high recurrence risk in HBV-positive Asian sHCC patients. Both tumor tissues and PANLT need to be considered together in future clinical practice to obtain a more comprehensive and accurate evaluation for recurrence risk.
CAZyme from gut microbiome for efficient lignocellulose degradation and biofuel production

Published: November 2022

Over-exploitation and energy security concerns of the diminishing fossil fuels is a challenge to the present global economy. Further, the negative impact of greenhouse gases released using conventional fuels has led to the need for searching for alternative biofuel sources with biomass in the form of lignocellulose coming up as among the potent candidates. The entrapped carbon source of the lignocellulose has multiple applications other than biofuel generation under the biorefinery approach. However, the major bottleneck in using lignocellulose for biofuel production is its recalcitrant nature. Carbohydrate Active Enzymes (CAZymes) are enzymes that are employed for the disintegration and consumption of lignocellulose biomass as the carbon source for the production of biofuels and bio-derivatives. However, the cost of enzyme production and their stability and catalytic efficiency under stressed conditions is a concern that hinders large-scale biofuel production and utilization. Search for novel CAZymes with superior activity and stability under industrial condition has become a major research focus in this area considering the fact that the most conventional CAZymes has low commercial viability. The gut of plant-eating herbivores and other organisms is a potential source of CAZyme with high efficiency. The review explores the potential of the gut microbiome of various organisms in the production of an efficient CAZyme system and the challenges in using the biofuels produced through this approach as an alternative to conventional biofuels.

In the advancement of novel materials, chemistry plays a vital role in developing the realm where we survive. Superalkalis are a group of clusters/molecules having lower ionization potentials (IPs) than that of the cesium atom (3.89 eV) and thus, show excellent reducing properties. However, the chemical industry and material science both heavily rely on such reducing substances; an in silico approach-based design and characterization of superalkalis have been the focus of ongoing studies in this area along with their potential applications. However, although superalkalis have been substantially sophisticated materials over the past couple of decades, there is still room for enumeration of the recent progress going on in various interesting species using computational experiments. In this review, the recent developments in designing/modeling and characterization (theoretically) of a variety of superalkali-based materials have been summarized along with their potential applications. Theoretically acquired properties of some novel superalkali cations (Li3+) and C6Li6 species, etc. for capturing and storing CO2/N2 molecules have been unveiled in this report. Additionally, this report unravels the first-order polarizability-based nonlinear optical (NLO) response features of numerous computationally designed novel superalkali-based materials, for instance, fullerene-like mixed-superalkali-doped B12N12 and B12P12 nanoclusters with good UV transparency and mixed-valent superalkali-based CaN3Ca (a high-sensitivity alkali-earth-based aromatic multi-state NLO molecular switch, and lead-founded halide perovskites designed by incorporating superalkalis, supersalts, and so on) which can indeed be used as a new kind of electronic nanodevice used in designing hi-tech NLO materials. Understanding the mere interactions of alkalides in the gas and liquid phases and the potential to influence how such systems can be extended and applied in the future are also highlighted in this survey. In addition to offering an overview of this research area, it is expected that this review will also provide new insights into the possibility of expanding both the experimental synthesis and the practical use of superalkalis and their related species. Superalkalis present the intriguing possibility of acting as cutting-edge construction blocks of nanomaterials with highly modifiable features that may be utilized for a wide-ranging prospective application.

HIF1A is significantly upregulated in calcified human aortic valves (AVs). Furthermore, HIF1A inhibitor PX-478 was shown to inhibit AV calcification under static and disturbed flow conditions. Since elevated stretch is one of the major mechanical stimuli for AV calcification, we investigated the effect of PX-478 on AV calcification and collagen turnover under a pathophysiological cyclic stretch (15%) condition. Porcine aortic valve (PAV) leaflets were cyclically (1 Hz) stretched at 15% for 24 days in osteogenic medium with or without PX-478. In addition, PAV leaflets were cyclically stretched at a physiological (10%) and 15% for 3 days in regular medium to assess its effect of on HIF1A mRNA expression. It was found that 100 μM (high concentration) PX-478 could significantly inhibit PAV calcification under 15% stretch, whereas 50 μM (moderate concentration) PX-478 showed a modest inhibitory effect on PAV calcification. Nonetheless, 50 μM PX-478 significantly reduced PAV collagen turnover under 15% stretch. Surprisingly, it was observed that cyclic stretch (15% vs. 10%) did not have any significant effect on HIF1A mRNA expression in PAV leaflets. These results suggest that HIF1A inhibitor PX-478 may impart its anti-calcific and anti-matrix remodeling effect in a stretch-independent manner.
