The development of competitive space hardware calls for continuing improvements in the accuracy of simulation of gas-dynamic processes in the space vehicle vicinity. This may contribute to extending the active life of spacecraft, thus improving the economic efficiency of space activities. In particular, quite a topical problem is the simulation of the interaction of rarefied jets from the propulsion system of a spacecraft with its individual components. To solve this problem in the case of a rather high surrounding vacuum, use is made of the molecular-kinetic concept of the gas structure based on the Boltzmann equation. The aim of this paper is to overview existing methods of simulation of gas-dynamic processes near spacecraft in a rarefied gas flow with account for propulsion system jets and to choose the most promising approaches to the solution of this problem. Among the methods considered, several main lines are set off: approximate, analytical, and numerical methods. Approximate methods use physical models of jet flow, approximation of numerical results, or a combination of both approaches. Analytical methods are based on essentially simplified assumptions and are intended for a very narrow class of problems. Numerical methods are the most universal tool of theoretical study. At the same time, each numerical method has a range of application of its own. At present, the most used and promising methods are statistical simulation methods: the direct simulation Monte Carlo method (DSMCM) and the test particle method (TPM). The former splits the continuous process of molecule motion and collisions in a rarefied gas into two successive independent stages (free-molecular transfer and relaxation) at each small time step. The simulation is done by time steps and in fact reproduces a nonstationary process. The latter, the TPM, consist in a statistical successive simulation of the wandering of test particles (molecules) on the background of field ones about the cells of the computational grid. Test particles, which move within the cells of the computational area, periodically collide with the obstacle in the flow and field particles, and in doing so they gradually change both their velocity and the field characteristics. For both statistical approaches, the simulation accuracy, as can be expected, is inversely proportional to the square root of the number of tests: the number of time steps and modeling particles for the DSMCM and the number of successively simulated test particle trajectories for the TPM. This may greatly affect the possibility of attaining a desired accuracy.

Published: July 2022

The purpose of this article is to develop a classifier and classification of technological processes in space to implement them on a space industrial platform. In the nearest future, mankind may face global challenges, first of all, the global warming problem and the problem of limited terrestrial resources. One of the obvious solutions to these problems is the industrialization of near space first and deep space and celestial bodies in the future. The initial stage of space industrialization is the construction of space industrial platforms in Earth orbits. The problem of space industrial platform construction is many-sided and requires various information. Currently, there exist works that are concerned to some extent or anther with the implementation of a number of technological processes in space, which are studied by scientists and developers in the relevant fields. Implemented in space, unique technological processes allow one to obtain materials with qualitatively new characteristics. The article presents a set of criteria for the classification of technological processes in space, a classifier developed on their basis for the classification of the processes in terms of their implementation on a space industrial platform, an analysis of technological processes to be implemented in space, and a set of their parameters to be provided on the platform. Using the classifier, functional diagrams of various technological processes implementable in near space are analyzed. The functional diagrams contain basic and auxiliary modules according to the process type. A relationship between the process and basic parameters of an industrial platform is shown. The freight flow, the communication and control channels, the power supply, and the thermal regime, ventilation, and vacuumizing assurance of the platform are determined and shown schematically.

Inventario de Humedales para Protección Costera (IHPC): una herramienta para la gestión costera en Costa Rica
Authors: Calleja Apéstegui Felipe , López-Arias Fernando
Published: July 2022

Costa Rica cuenta con aproximadamente 1 500 km de costa, en los cuales se localizan humedales que ofrecen una gran variedad de servicios ecosistémicos, entre ellos la protección costera. La cuantificación de este servicio requiere investigación en estos humedales, siendo necesario tener un inventario que ofrezca tanto su localización como sus características físicas y las de su entorno. Este tipo de inventario no existe específicamente para los humedales costeros del país, por lo que el objetivo de este trabajo es generar la primera versión de un inventario de humedales que ofrecen protección costera en Costa Rica. Se tomó como base el Inventario Nacional de Humedales (INH) y una cartografía de manglares del año 2005. Los humedales costeros no incluidos en esas fuentes fueron identificados con un procedimiento semiautomático, analizando índices de vegetación derivados de imágenes del satélite Sentinel 2 y una delimitación manual basada en ortofotos del año 2017. El nuevo inventario consiste de 464 humedales costeros, de los cuales 180 son zonas nuevas no incluidas en el INH. A estas se les incluyó la información contenida en el INH, de forma que ambas fuentes de información sean compatibles. Unido a esto se caracterizaron, en los 464 humedales, algunas condiciones naturales y antrópicas que podrían afectar posibles investigaciones relacionadas a la protección costera. El resultado es una base de datos geográfica, accesible a todo público, con la localización y caracterización general de los humedales, que podría usarse en investigaciones tanto de protección costera como del ámbito costero en general.
Evaluación de la validez de factores de corrección para estimar la incertidumbre estándar de una distribución triangular con un intervalo de cobertura del 95 %
Authors: Molina-Castro Gabriel
Published: July 2022

Recientemente, la estimación de incertidumbre de medida se convirtió en un tópico de gran interés para el reporte de inventarios de gases de efecto invernadero (GEI) en Costa Rica. En este contexto, una guía metodológica nacional del Programa País de Carbono Neutralidad (PPCN) ha surgido como base para el desarrollo local de esta temática, pero unos pocos aspectos de su contenido carecen de una explicación clara que justifiquen su implementación. El presente estudio evalúa la validez del uso de factores de corrección, propuestos por esta guía, que amplían la incertidumbre estándar estimada mediante el ajuste una distribución triangular, en presencia de un intervalo de cobertura del 95 %. Para ello, se simularon 3124 escenarios de distribuciones triangulares y se les estimó una incertidumbre estándar considerando que los límites simulados delimitan un intervalo de cobertura al 100 % (u100) y otra considerando un intervalo de cobertura al 95 % (u95), evaluando dos posibles interpretaciones sobre la ubicación del intervalo para esta última. Los factores de corrección FC se estimaron para cuatro diferentes grupos de escenarios como las pendientes entre u95 y u100, estimadas a partir de una regresión por mínimos cuadrados utilizando el software estadístico R. Se obtuvieron resultados entre 1,23 y 1,29, con un valor global de 1,25. Estos valores son consistentes con los encontrados en la guía metodológica nacional, comprobando así su validez y aplicabilidad. Finalmente, se sugiere el uso del factor de corrección de 1,25 como aproximación práctica para todos los escenarios evaluados, lo que podría facilitar su implementación homologada por los usuarios.

Authors: Araya-Porras Enoc , Mora-Calderón Andrey , Aguero-Valverde Jonathan
Published: July 2022

It is necessary to analyze pedestrian behavior at crossings to improve their safety and mobility. Mid-block pedestrian crossings are structures that facilitate the mobility of pedestrians, safeguarding them from vehicular traffic; however, illegal crossing by pedestrians is an everyday occurrence and represents a risk to their safety. The purpose of this study is to evaluate the relationship between different human and road factors and the decision to illegally cross signalized mid-block crossings. Several human factors such as age, gender, waiting time in traffic light, use of the pushbutton and individual or group crossing, as well as road characteristics such as the length of traffic light phase, length of crossing, and vehicular volume were analyzed. To collect information about these variables this study recorded a one-hour video in six selected crosswalks within the Montes de Oca County in Costa Rica. A total of 1,707 crossings were recorded, 10.6% of which corresponded to instances of illegal crossing. After applying a logit model, this research found that traffic volume, pedestrian red-light time, waiting time, vehicle illegal crossing and group crossings reduced the probability of violations by pedestrians. On the other hand, minimum traffic light time and crossing length increased the possibility of pedestrian illegal crossings. This study concluded that the traffic light cycle is an important variable that must be rigorously analyzed to ensure pedestrian's compliance with traffic lights, which will improve the safety of the pedestrian mid-block crossings.

Published: July 2022

Background. Child and adolescent suicides remain one of the most painful public issues. The COVID-19 pandemic has aggravated this topic as the number of suicides among children population has increased in this period. Research and practice guidelines identify the leading role of primary care physicians in the prevention, identification, and routing of patients with suicidal behavior. At the same time, there were no studies on pediatricians’ competence in the field of suicides.

Objective. The aim of the study is to study pediatricians’ competence in prevention, risk determination or and detection of suicidal behavior.

Methods. Cross-sectional study was conducted with the usage of original electronic questionnaire aimed on identifying the level of pediatricians’ competence in evaluating suicidal behavior in children. Questionnaire included 18 questions.

Results. We have received 208 electronic questionnaires. 97.1% of specialists have confirmed that they evaluate emotional status of their patients during admission. During admission: 86.1% of specialists have considered the characteristics of children appearance, facial expression, voice intonation, 65.4% — have asked questions about mood, 62.5% — have interviewed parents. 98.6% of specialists pay attention to the presence of self-inflicted injuries marks, 88.4% — ask about the origin of these injuries. Only 36.1% of respondents ask patients about suicidal thoughts, intentions, or actions. Only 69.3% of specialists are ready to refer their patients to psychologist, and 51.7% — to psychiatrist.

Conclusion. Even though most surveyed pediatricians notice signs of suicidal intent (low mood, self-inflicted injuries), they avoid discussing the topic of suicide during admission. Increasing the competence of pediatricians should be aimed on destigmatisation in the field of mental health, increasing the knowledge level, and developing practical skills in working with children with suicidal behavior.
Regression Analysis of Some Service Expenditures on The Nigeria Gross Domestic Product (GDP)
Authors: Ogolo Ibinabo Magnus
Published: July 2022

Between 1981 and 2021, this research work looked at the test for equality of regression models employing some service expenditures on the Nigerian GDP. This study has five particular objectives that were created and used. Relevant related literatures were reviewed based on the factors
in the objectives. This study used secondary data acquired from the National Bureau of Statistics and the Central Bank of Nigeria statistical bulletin, which included 46 activity sectors. The data was analyzed using multiple regression models. MINITAB 16 and Microsoft Excel 2010 were used
for all calculations. The series plot results for each service expenditures indicate an upward trend for the whole plot, implying a linear link between expenditures and Nigeria's total GDP. To find the significant parameters and test for model equality, the Durbin method of estimating a multiple
regression model was used; this revealed that all of the models' parameters estimates were not significant at 5%, which appears biased. Model (1), the Military Government Period Model, was found to be the "best" of the three regression models, with the highest R2 and Adj.
R2 values of 99.8%, the smallest AIC and BIC values of 170.356 and 174.134, and the highest F-value of 4494.669 determined. According to the findings, the government should devote a smaller amount of its budget to recurrent spending and focus more on capital spending, such as agriculture,
education, and health, as it is the primary driver of economic growth.

Effects of stirrup ratio and shear–span ratio on shear failure of geometrically similar RC columns
Authors: Li Ping , Jin Liu , Du Xiuli
Published: July 2022

Very few studies have been dedicated to the size effect on the shear behaviour of reinforced concrete (RC) columns. In particular, there lacks a design equation that can quantitatively represent the effect of related parameters on the size effect on nominal shear strength for RC columns. This work presents a mesoscale numerical analysis of the mechanical response of geometrically similar RC columns subjected to constant axial load and monotonic lateral load. In the numerical model, the inherent heterogeneous nature of concrete and steel/concrete interaction were considered. The numerical model was validated against test results in the literature, and then adopted to conduct a parametric study of the shear behaviour and size effect of RC columns. The investigated parameters involved the shear–span ratio, stirrup ratio and axial load ratio. The results indicated that the nominal shear strength presents an obvious size effect. This size effect on nominal shear strength was gradually weakened as the stirrup ratio and shear–span ratio increased. Moreover, considering the quantitative influence of stirrup ratio and shear–span ratio on size effect, a modified equation was derived to predict the shear resistance of RC columns. Through comparing with available experimental results, the modified equation was demonstrated to be accurate and reliable.
Quantifying Non-Tariff Measures by Combining Cointegration Tests and Simulation Models with an Application to the Korean Beef Market
Authors:   The Korea International Trade Research Institute, Soon Byung-Min , Han Seok-Ho
Published: July 2022

Purpose This study quantifies the non-tariff measures on the Korean beef market using a cointegration test and simulation model. Design/Methodology/Approach This paper introduces a hybrid approach which combines cointegration analysis and a simulation model. We assume that there are sanitary and phytosanitary measures in the Korean beef market after banning U.S. beef in 2004. Hence, we use cointegration test results using domestic and U.S. beef prices to calibrate simulation model for the Korean beef market. The approach follows the steps of (1) cointegration tests, (2) a partial equilibrium model, and (3) calculating an Ad-valorem equivalent SPS measure. Findings The results show that the Ad-valorem equivalent SPS measure is 77%. This size is larger than the 55% derived by the traditional price gap approach. Research Implications This study provides a hybrid model to quantify an SPS measure. We take the Korean beef market as there could be non-tariff barriers after the Bovine Spongiform Encephalopathy event in 2004. Our study not only quantifies the NTM in the Korean beef market but also introduces a hybrid approach for quantifying the NTM. Hence, our approach can apply to other studies related to NTM.

Purpose This paper addresses that wrong bailout programs would end up with not only misuse of public money but also lowering aggregate productivity of industry. Public resources should be allocated towards high-productivity firms. This paper guides how a government can screen firms. Design/Methodology/Approach This paper presents a principal-agent model of incorporating accountability. It will provide policy-makers an incentive scheme to extract private information of productivity from firms. Findings Whenever demand parameter is known, the firm profit can be expected using the information of productivity. Thus, the government normalizes distribution of firm profits based on reported productivity. If the realized profit falls significantly below the confidence interval, the firm is presumed to be a liar and is punished. That is, a bail-out firm takes accountability of own report. Accountability helps bailout programs to be truthfully implementable. Research Implications Public resources should be allocated towards high-productivity firms. Thus, firm screening is needed.

A global priority of electrification expansion in all areas is also stated in the Energy Strategy of the Russian Federation. The study aims to forecast electricity demand in Russia taking into account possible electrification options in economic sectors. The article presents a multi-stage procedure and a concise review of methodological approaches to the long-term assessment of electricity demand, which considers the impact of complex interrelationships in social, economic and technological policies. In particular, this approach focuses on the regional level, where the interests of energy producers and consumers are reconciled. The current and promising directions of electricity use in Russian regions and economic sectors were analysed based on various statistics and forecasts. The conducted analysis demonstrated the stability of sectoral and territorial energy consumption patterns, as well as a decrease and convergence of values of gross regional product (GRP) energy intensity. Energy consumption of regions varies due to significant differences in industrial specialisation and living standards of the population. The highest energy consumption is observed in developed regions (Central Federal District) or regions with a large share of energy-intensive industries (Siberian Federal District). According to the accepted economic development and electrification expansion strategies for the period 2025–2040, on average, electricity demand in Russian regions is expected to increase by 1.4–1.8 % annually. It is anticipated that the Siberian and Far Eastern Federal Districts will show the highest growth rates of energy consumption due to the accelerated development of these territories. Predicted dynamics of the gross domestic product (GDP) energy intensity in Russia confirms its compliance with global trends. The research findings may prove useful in creating programmes and development strategies for the country and its regions.

Sustainable regional development should consider the state and improvement of the quality of regional human capital. To this end, the present study focuses on economic assessment of human capital. Additionally, the research analyses the definitions of the “human capital” category, as well as approaches to identifying its composition and structure. After examining various economic assessment techniques, a definition of regional human capital was proposed. The cost approach was chosen as the most suitable tool for the economic assessment of human capital at the regional level. For economic valuation, the study uses a method developed by Chigoryaev and co-authors, including a number of theoretical and methodological modifications that take into account regional specificities. According to the assessment results, the total human capital in Kamchatka krai exceeded 191 billion roubles, of which more than 104 billion accounted for the fixed human capital. The constant growth of human capital in the period 2011–2018 was noted. Simultaneously, the share of the fixed human capital in the overall structure has been steadily increasing. The values of the chain growth rate of the operating human capital ranged from 1.0 to 1.06, while the values of this rate of the fixed human capital ranged from 1.14 to 2.05. A comparative analysis of the ratio of the total human and physical capital showed the presence of an imbalance: the share of human capital was gradually increasing and reached 37.5 % in 2018. The obtained results can be used to create strategic and programme documents in the field of regional socio-economic development. The modified method of Chigoryaev and co-authors can be applied for the valuation of regional human capital in other studies.

An important problem of the impact of institutional infrastructure on the decomposition and spatial development transformation of regions of various hierarchical ranks, including the Arctic zone that is divided between the Arctic countries according to the national principle, is insufficiently studied. The majority of scientific works devoted to this issue mostly focus on the traditional economic assessment of the sectoral effect of activities and the concept of spatial economics. Thus, methodological approaches to the study of infrastructure and institutional structure should not rely on the traditional principles of mainstream economics. Instead, they should be based on the system-evolutionary model of modern natural science and should be closely related to such an indicator of system development as self-organisation. Internal (endogenous) and external (exogenous) elements of infrastructure cause stability (order) and chaos (disorder) in the development of systems, as well as lead to the interrelated and balanced formation of hierarchical and heterarchical organisational models of regional spatial units. This methodological approach also applies to institutional infrastructure. The present study provides theoretical justifications and methodological approaches corresponding with the aforementioned principles of infrastructure research, designed for the regions of the Arctic basin. In terms of scientific practice, it is proved that the intensification of institutional infrastructure in the Pacific Arctic depends on the creation of the Russian-American Bering/Pacific-Arctic Council (BPAC). Various expert communities discussed these proposals at several international conferences. At present, however, their practical implementation became impossible due to complicated geopolitical situation. Despite this, it is necessary to continue research aimed at the improvement of institutional structures and coordination of interactions between the Arctic regions, especially in cross-border areas of neighbouring countries. The obtained findings will definitely be useful for the Arctic community, when a reasonable approach to this problem will again prevail over geopolitical disputes.

Este trabajo forma parte de los resultados de una investigación que tiene como objetivo comprender las influencias del turismo después de la implementación del Parque Estatal Serra do Brigadeiro (PESB) en el paisaje de Araponga - MG., utilizado como marco de tiempo desde 1996 hasta 2020. Discute el papel del paisaje en la discusión sobre el patrimonio cultural en una pequeña ciudad de Minas Gerais, considerando que recibe influencia del turismo proveniente del PESB. Al acercarnos al "paisaje" consideramos aspectos morfológicos y simbólicos de este término polisémico, se toma que está ligado a la forma en que las personas experimentan y se manifiestan en el espacio, por lo tanto, se trata del interés de comprender la percepción de la comunidad que utiliza el paisaje, ya sea como vivienda, trabajo o fuente de alimento. El Parque Estatal Serra do Brigadeiro fue inaugurado en medio de conflictos, tales conflictos permitieron el reconocimiento de una comunidad unida dispuesta a luchar por el uso de su espacio, siendo Araponga uno de los protagonistas en este contexto. Hubo, más tarde, la búsqueda del equilibrio entre la mirada externa, del especialista en patrimonio cultural o ambiental, y la mirada de la comunidad local que percibía y utilizaba ese espacio.  El estudio del paisaje exige comprender aportes que vayan más allá de lo visto, por lo tanto, es necesario profundizar en las relaciones sociales presentes en la memoria e historia de un grupo determinado para comprender los cambios que ocurrieron y sus significados, así como conciliar perspectivas externas e internas al municipio.
Role of Science, Technology, Executive, and Public (STEP) in Environmental conservation and waste management and the scenario in Politically and Militarily Conflicted Regions (PMCRs) of the world

Environmental conservation and waste management is a great challenge around the world. The realization of safe water, air, sanitation, and hygiene (WASH) for the world is a distant dream. Barring few developed countries, the rest of the world, and more importantly, the third-world countries are struggling hard to achieve safe WASH. India and China are no exceptions. Given the massive population of these two countries, open defecation issues, unscientific waste disposal practices, and poor health and hygiene infrastructure; achieving safe WASH remains a challenge. While science and technology for the conservation of the environment and waste management are advancing day by day, active participation of the executive and the public is insignificant at least in PMCRs. STEP minus E or/and P can’t solve the challenges of environmental conservation and waste management. Safe WASH demands enormous attention from science, technology, executive, and the public (STEP) coherently.

Özetİnsan nüfusunun yaşlanması nedeniyle kronik böbrek hastalığı (KBH) gibi hastalıkların prevalansı her geçen yıl artmaktadır. Kronik böbrek hastalığı, böbrek yapı ve işlevini etkileyen heterojen bozuklukları ifade eden genel bir terimdir. Glomerüler filtrasyonda azalmayı takriben böbreğin sıvı-solüt dengesini ayarlama yeteneğinde, metabolik ve endokrin fonksiyonlarında kronik ve progresif bozulma durumu olarak tanımlanabilmektedir. KBH sıklıkla yaşlıları etkilemektedir. Yaşın ilerlemesiyle birlikte böbreklerde birtakım yapısal ve fonksiyonel değişiklikler ortaya çıkar. Dolayısıyla, gelecekte hafif ve orta dereceli KBH’dan muzdarip hasta sayısının artması beklenmektedir. KBH, kalp ve beyin gibi diğer organlara zarar veren derin metabolik ve hemodinamik değişikliklere yolaçar. Merkezi sinir sistemi anormallikleri ve bilişsel eksiklik, KBH’nın şiddeti ile ilerlemekte ve çoğunlukla hemodiyaliz hastaları arasında ortaya çıkmaktadır. Ayrıca bireyleri sosyo-ekonomik yönden de etkilemektedir. Hastalarda KBH risk faktörlerinin erken tanınması temel noktayı oluşturmaktadır. Bu nedenle, risk altındaki gruplarda uygulanacak olası önleyici ve koruyucu tedavilerin tespiti ve hastalığın tedavisi için bu mekanizmaların incelenmesi gerekmektedir. Bu derleme, ilgili mekanizmalar hakkında mevcut bilgileri sunmaktadır.

Özet
Amaç: Diyabetes mellitus birçok organı etkileyen komplikasyonlarla giden bir hastalıktır. Diyabetin retinopati, nefropati, nöropati ve makrovasküler komplikasyonları iyi bilinmekle birlikte akciğer üzerine etkileri yeteri kadar çalışılmamıştır. Bizim bu çalışmamızda amacımız tip 2 diyabetes mellitus’un solunum fonksiyon testlerine etkisin incelemektir.
Gereç ve Yöntemler: Tip 2 diyabetli 51hasta (15’i erkek, 36’sı kadın) ve 49 sağlıklı kontrol (24’ü erkek, 25’i kadın) olmak üzere toplam 100 kişi çalışmaya dâhil edildi. Diyabetli hastalardan 8-12 saatlik açlık kan şekeri, HbA1c, tokluk kan şekeri, kreatinin, alanin Transaminaz (ALT), hemogram, spot albümin, spot
kreatinin tahlilleri istendi. Tüm hastaların göz ve nörolojik muayeneleri ilgili branşlarda yaptırıldı ve diyabetik nöropati, nefropati veya retinopati saptanan hastalar kaydedildi. Tüm katılanların solunum fonksiyon testleri yapılarak 1 saniyedeki zorlu ekspiratuar volüm (FEV1), zorlu ekspiratuar volüm 1 sn/zorlu
vital kapasite (FEV1/FVC), karbonmonoksit difüzyon kapasitesi (DLCO%) değerler ölçüldü ve iki grup arasında karşılaştırmalar yapıldı.
Bulgular: Diyabetli hastalarda FEV1 değeri ortalama 92.84±8.94 ml iken, kontrol grubunda 96.95±9.2 ml olarak saptandı. Diyabetli grupta FEV1 daha düşük bulundu ve arasındaki fark istatistiksel olarak anlamlıydı (p=0.026). Diyabetli hastalarda DLCO değeri 96.21±10.8 mmol/kPa/dk iken kontrol grubunda bu değer 97.95±10.1 mmol/kPa/dk idi ve tip 2 diyabetlilerde daha düşük olmasına rağmen aralarındaki fark anlamlı değildi (p=0.41). Diyabetli hastalarda FEV1/FVC oranı 82.15±6.77 iken, kontrol grubunda ise 83.73±5.87 olarak saptandı ve aralarındaki fark anlamlı değildi (p=0.21).
Sonuç: Tip 2 diyabetli hastalarda kronik hiperglisemi olması mikroanjiopatik hasara yol açarak özellikle retinopati, nöropati ve nefropati gibi komplikasyonlara sebebiyet vermektedir. Diyabetin akciğer üzerindeki etkilerini inceleyen çalışma sayısı çok azdır. Çalışmamızda tip 2 diyabetli olanlarda kontrol grubuna göre solunum fonksiyonlarında sadece FEV1 değerlerinde bozulma olduğunu saptadık. Bununla birlikte bu konuda daha geniş kapsamlı çalışmalara ihtiyaç olduğunu düşünmekteyiz.
