ЗАСТОСУВАННЯ МАТЕМАТИЧНОЇ МОДЕЛІ ІНТЕРПОЛЯЦІЇ КУБІЧНИМ СПЛАЙНОМ ПРИ АВТОМАТИЗАЦІЇ АЕРОНАВІГАЦІЙНОЇ СИСТЕМИ
Authors: Козак Є.Б.
Published: October 2022

У статті розглянуто принципи застосування математичної моделі інтерполяції кубічним сплайном при автоматизації аеронавігаційної системи. Підкреслено, що на відміну від дискретного рівняння, що описує стан і вимірювання в дискретній моделі, еволюція випадкового процесу і вимірювань в часі у стохастичній диференціальній моделі може бути описана диференціальним рівнянням стану і дискретним рівнянням вимірювання. Зазначено, що стохастичні диференціальні рівняння мають два методи аналізу: сильні рішення і слабкі рішення, і тільки деякі типи стохастичних диференціальних рівнянь відносяться до замкнутих рішень з сильним рішенням; в той час як слабке рішення є розподіленим рішенням, тобто ймовірністю в безперервному функціональному просторі. Наголошується, що у стохастичних диференціальних рівняннях броунівський рух являє собою лише рушійну силу мікроскопічних випадкових флуктуацій, а не появу у властивості макроскопічного середнього. Слабке рішення стохастичного диференціального рівняння визначається функцією передачі. Обґрунтовано алгоритм кубічного сплайна, який є одновимірним випадком, щільність ймовірності сегментована для апроксимації апріорної щільності ймовірності стану системи, він безпосередньо вирішує функцію щільності ймовірності стану системи, щоб більш чітко зрозуміти різні можливості стану. Шляхом побудови умов інтерполяції кубічним сплайном, у статті дана функція використовується для апроксимації рішення прямого рівняння Колмогорова, щоб перетворити завдання в рішення системи звичайних диференціальних рівнянь відносно коефіцієнтів в кусковій функції. Математично доведено, що оптимальне рішення оцінки стану можна отримати за формулою Байєса, але перш за все необхідно знати попередню функцію щільності ймовірності стану системи та дослідити доцільність використання методу кубічного сплайну для його вирішення. Запропоновано алгоритм інтерполяції кубічного сплайну, який перетворює часткові диференціальні рівняння щільності ймовірності стану в часі в рішення звичайного диференціала рівняння кускової функції та розв'язує стан системи в одновимірному просторі функцій.

TACTILITY OF «ONE’S OWN» BODY AND THE BODY OF THE «OTHER» IN O. MANDELSTAM’S POETOLOGY
Authors:   Novosibirsk State Pedagogical University, Maroshi V. V.
Published: October 2022

The intertextuality of Mandelstam’s poetry is considered in the article from the point of view of its bodily and poetological aspects. The desire for bodily contact with the “other” world finds its expression in the verbal representation of touch or a kind of “haptic poetology”, the reflection of the verbal as partly tactile. The intensity of the representation of tactile sensations and their metaphorical use in Mandelstam’s poetry is unusual. The article analyzes various ways of his identification with both the lyrical heroes of Russian poets and the diseases of the poets themselves (A. A. Fet, F. I. Tyutchev, I. F. Annensky). In the poet’s articles, he attributes his own tactile attitude to the word to V. V. Rozanov, I. F. Annensky.

The article is devoted to the relations between N. Ya. Prokopovich (1810 1857) and his great namesake, when they started their adult life, in particular stories with the idyll “Hanz Küchelgarten” (1829). Only after Gogol’s death, Prokopovich announced to P. Kulish, the writer’s biographer, that he accidentally found out about the authorship of that “poem” and the annihilation of its entire circulation. However, our research suggests that it was conceived by two Nikolays, although its text was mainly written by N. Prokopovich. N. Gogol-Yanovsky took an active part in its creation, and then, believing in its success, became its publisher. After the failure, he, feeling guilty before a friend, entrusted him to edit the first edition of the comedy The Inspector General and his first Collected Works.

What is Included in the Concept of Online Arbitration in China?
Authors:   Law Institute, Peoples’ Friendship University of Russia (RUDN), Moscow, Ermakova Elena P.
Published: October 2022

The article provides an overview of new forms of dispute resolution – online arbitration on the example of China. Chinese scientists divide online arbitration into two categories: mandatory online arbitration and optional online arbitration. It is proved that optional online arbitration in China, which is currently conducted by private e-commerce platforms (“Taobao ODR”, “Tmall ODR”, “Jingdong ODR”, “Gome ODR”, etc.) and providing crowdsourcing dispute resolution services, can be considered as a fullfledged online arbitration. The only difference between mandatory and optional online arbitration is that the decisions of the latter cannot be enforced through a state court. But e-commerce platforms in China have effective incentives to force the losing party to enforce the arbitration award.

Published: October 2022

Formulation of the Problem. The uncertainty of the legal status of the Russian judicial school, the functions of which are entrusted to the Russian State University of Justice, creates obvious inconsistencies between the legal foundations for additional professional education of judges in the Russian Federation and the needs and demands for continuous training of judges. Purpose of the Work: to determine the principles of additional professional judicial education, the legal forms of their implementation in models of additional professional education, tested in Russia and foreign countries, as well as to develop proposals for improving the legal regulation of the organization of additional professional education in our country. Results, Brief Conclusions. The following are identified as principles for organizing additional professional education for judges: lifelong learning as a status duty of judges; autonomy and independence of an educational institution that performs lifelong learning tasks. The features of the legal forms of implementation of these principles in the models of additional professional education of judges, tested in a number of foreign countries, are revealed. The article concludes that there is a need for further legislative consolidation of the Russian State University of Justice as an independent judicial school, as well as the organization of additional professional education for judges, including the legalization of the frequency, grounds and terms of training, the nature and amount of funding for additional professional education, and liability for dishonest attitude to training.

The article attempts to determine the features of public interest and its application in decisions of the Constitutional Court of the Russian Federation of the Supreme Court of the Russian Federation on taxis sues. Since the very concept of public interest acts as an abstract one and does not reflect the connection with the specific needs of society, a proposal is formulated to create a separate legal institution of goal-setting, through which it is possible to link public interests with the real results of the state’s administrative activities. Such a measure will allow minimizing cases of substitution of public interests by quasi-public interests of certain groups of officials. The role of the Constitutional Court of the Russian Federation of the Supreme Court of the Russian Federation in the legalization of the term “public interests”, disclosure of the relationship of public interests with a number of the most important constitutional values. The author notes the problem in the interpretation of public interests as an object of protection by the judicial authorities, which consists in the fact that the courts themselves have no right to take under their protection those cases of conflicts in the sphere of interests, if the regime of such interests is not determined by the legislator. The logistics of the formation of public interests and the role of amendments to the Constitution of the Russian Federation as the basis for disclosing the content of public interests are named.

Published: October 2022

La política internacional no se puede entender sin saber qué es lo que dijeron los corresponsales de prensa en cualquier país. Los acontecimientos que se están viviendo en tierras ucranianas actualmente puede ser que se hubieran minimizado con una buena labor diplomática. Los periodistas de los medios de comunicación reflejaron muchas circunstancias durante la campaña electoral rusa de 2008. Aquella fue una fecha clave dónde Vladimir Putin traspasaba momentáneamente su poder a Dmitry Medvédev. El panorama internacional desde entonces empezó a cambiar y el periodismo también. Las historias se encuadraban todavía en un periodismo de corte tradicional.

Aim. We present our experience of performing the simultaneous video-assisted mediastinal lymphadenectomy (VAMLA) and videothoracoscopic (VTS) sleeve (bronchoplastic) lobectomy for central cancer of the left lung.
Material and methods. Two patients with central cancer of the left lung have been examined and treated at Municipal Multi-field Hospital № 2. Under single exposure of anaesthesia the patients underwent simultaneous VAMLA and dual-port VTS sleeve (bronchoplastic) lobectomy with circumferential bronchial resection and formation of broncho-bronchial anastomosis.
Results. No intraoperative adverse events were recorded in both presented cases. Prolonged parenchymal air-leak was observed only in one of the patients during the postoperative course. No other adverse events were registered. Anastomoses of both patients were in a good state at the controll bronchoscopy, and both were discharged for ambulatory treatment in satisfactory condition. The pN0 stage was confirmed with both cases, based on morphological examination of 31 and 28 mediastinal lymph nodes, respectively.
Conclusion. Our data demonstrate the advantages of the simultaneous VAMLA and VTS sleeve (bronchoplastic) lobectomy as a single-step surgical procedure in treatment of patients with central non-small cell cancer of the left lung.

Published: October 2022

Summary. Aim of the study: Based on new knowledge about the course of acute and chronic cholangitis in patients with obstructive lesions of the bile ducts to improve the results of diagnosis and treatment, using improved algorithms and new minimally invasive technologies.

Materials and methods. 200 patients with acute and chronic cholangitis were selected. There were 93 men — 107 men, the age of patients ranged from 25 to 79 years, the average age was (61,8 ± 2,4) years.

Results and discussion. Reconstructive surgery for choledochal strictures should be performed if the patient’s condition allows as early as possible (preferably within 3–4 weeks after symptomatic minimally invasive biliary tree decompression) to prevent the development of irreversible cirrhotic changes in the liver parenchyma.

Conclusions. Minimally invasive interventions are effective both in the treatment of cholangitis due to intraductal causes, where they are the ultimate treatment, and as a first-line method of preparation for major radical intervention in severe anatomical changes in the biliary system.
Applications of the Conway-Maxwell-Poisson Hidden Markov models for analyzing traffic accident
Authors:   The Korean Data Analysis Society, Kim Hee-Young
Published: October 2022

This paper documents the application of the Conway-Maxwell-Poisson(CMP) hidden Markov model for modelling motor vehicle crashes. The CMP distribution is a twoparameter extension of the Poisson distribution that generalizes some well-known discrete distributions(Poisson, Bernoulli and geometric). Also it leads to the generalizations of distributions derived from theses discrete distributions, that is, the binomial and negative binomial distributions. The advantage of CMP distribution is its ability to handle both under and over-dispersion through controlling one special parameter in the distribution, which makes it more flexible than Poisson distribution. We consider the data consisting of the daily number of injuries on the road in 2020 from the TAAS(Traffic Accident Analysis System). We apply CMP hidden Markov model to data, the parameters are estimated via maximim likelihood, and find that this model achieves better performance than commonly used Poisson hidden Markov model. For the decoding procedure, the Viterbi algorithm is implemented.
Prediction of Chinese cabbage price using growing season weather**
Authors:   The Korean Data Analysis Society, Park So-Yeon , Kim Dong-Eon , Kim Min Soo
Published: October 2022

Domestic production of Chinese cabbage accounts for more than imports. As global warming intensifies, weather factors are expected to play an important role in the price fluctuations of Chinese cabbage due to the increase in the frequency and intensity of abnormal climates. Therefore, this study intends to predict the price of Chinese cabbage by using the weather factors for each growth stage considering the production of the main production area by cropping pattern. Based on the wholesale price of high-grade Chinese cabbage from May 20, 2015 to June 30, 2022, meteorological data for the same day and growth stage were also used in this study. The price of Chinese cabbage was predicted through Long Short-Term Memory(LSTM) and Gated Recurrent Unit(GRU), which are recurrent neural network models, and evaluated based on Root Mean Square Error(RMSE) and Mean Absolute Error(MAE). As a result of the analysis, the absolute difference in price was the smallest when forecasting reflecting the average of insolation during total growing, average of insolation during planting and sowing, and average of minimum grass temperature after planting and during harvest. When the price fluctuation trend was steep, more accurate prediction was possible when the weather of the day was also reflected. In this study, it is difficult to take into account the variation of individual growing seasons by day by applying the average data of a certain growth period to all cropping pattern in question. It is expected that a more accurate prediction can be obtained if the follow-up study is conducted by collecting the growth stage period by farmhouse. Through this study, it is expected that it will help farmers and consumers to sell and purchase based on the predicted price by properly applying weather variables after identifying the trend of the price of Chinese cabbage in the future.
Estimation and Prediction Model for Functional Spatial Data and Application
Authors:   The Korean Data Analysis Society, Yang Hojin
Published: October 2022

Particulate matter consisting of the chemical compounds harmful to human body and floating in the air as the invisible dust has been affecting on the air pollution or the various disease by inhaling into the human body. According to the Korea Meteorological Administration’s open portal, the particulate matter is measured at 28 sites and is widely used in forecasting and warning systems related to the particulate matter. In this paper, we will introduce an approach that can estimate the fixed effect and predict the future value by incorporating the spatial approach with the functional approach, assuming that the nature of the measurement for the particulate matter is a functional nature. While the existing studies have focused on the longitudinal data approaches, these approaches did not consider the characteristics of the spatial data that can have dependency between the sites and of the irregularity that the sites are not uniformly distributed across the spatial domain. To address this issue, we consider extending the existing approach to the functional data approach and applying the spatial approach such as kriging. Specifically, we consider the weighted mean being insensitive to extreme observations to account for the fixed effect from the real data obtained from 28 sites for 2021 year. To do this, we estimate the covariance process and compute the optimal weight through the empirical variogram analysis. Also, we apply a kriging method that can predict the value associated with the particulate matter at any given observational site.
Asymmetric Relationship between House Sale Price and Jeonse Price
Authors:   The Korean Data Analysis Society, Choe Jong-Il , Chang Byoung-Ky
Published: October 2022

The asymmetric relationship between the sale price and the Jeonse price in the housing market was examined in this study. When the sale(Jeonse) price increases compared to when it decreases, would not the impact on the Jeonse(sale) price be different? It started with the question. Analysis was performed using the nonlinear autoregressive distributed lag(ARDL) bounds test, which satisfies the purpose of this study. By applying the component decomposition method suggested by Hatemi-J and El-Khatib(2016), the positive and negative impacts were separated. To compare regional differences, data from 15 regions as well as the whole country were used. The most noteworthy thing from the analysis results is that, at least in the short term, the effect on the Jeonse price is bigger when the sale price decreases than when it increases, and the effect on the sale price is greater when the Jeonse price increases than when it decreases. This would be consistent with the rational actions of market participants to avoid negative-gap investments or Jeonse price reversal. On the other hand, in long-term relationships, it is estimated that the sale price leads the Jeonse price, and indirectly supports the theory of substitute goods. The findings of this study may be helpful in formulating supply and demand strategies for policy makers as well as in predicting future housing prices and deciding when to buy or sell a home.

To do this, 9th to 11th waves of the Panel Study of Korean Children(PSKC 2018) were utilized, and generalized propensity score method applied. The results of this study were as follows. First, happiness, self-esteem, concentration, positive parenting attitude significantly influenced on students’ grit score(perseverance of efforts). The frequency of conversation with parents, the smart phone and PC utilization, and the sense of alienation affect students' grit score(consistency of interest). Second, Grit had a positive effect on students' happiness, self-esteem, life satisfaction, and peer relationships. Third, Grit showed differential effects on emotional, and social development according to the type of student's life-long goal, and the level of household income. Based on these results, the implications of this study and suggestions for future study were discussed.

Population dynamics of African palm weevil (APW) (Rhynchophorus phoenicis F.) was studied. Four oil palms were randomly selected and sizeable wounds were created, using an axe and cutlass and monitored for arrival of APWs for 21 days. Total number of one hundred and fourty-eighty (n=148) weevils were counted at the breeding sites. The total number of males was 52(35.13%), while the total number of females was 96(64.87%) which corresponds to sex-ratio of 1:1.9. Colonization of the breeding sites commenced with the arrival of few females in the morning (7-9am) followed by the males at noon (1-2pm) and significantly increased in population to peak by 1-3pm till evening and steadily declined at dusk. The population of APWs was significantly higher (P<0.05) in younger oil palms than older palms: Youngest Palm (P1) had 62, Younger Palm (P2) had 66 and Older Palm (P3) had only 20, while the Oldest matured Palm (P4) had no weevil because the tissues did not decompose. Optimum temperature and relative humidity which favoured the aggregation of R. phoenicis at the breeding site was 300C - 310C and 75-82% respectively. Also, the population of R. phoenicis at the breeding sites was highly positively and negatively correlated with the temperature (r=0.96) and relative humidity (r=-0.98) respectively. The APWs were sluggish in the morning but became active in feeding, courtship, mating and oviposition of eggs at noon when the temperature of the day become hotter and declined at dusk.
Loop-erased random walks associated with Markov processes
Authors: Dorogovtsev A.A. , Nishchenko I.I.
Published: October 2022

A new class of loop-erased random walks (LERW) on a finite set, defined as functionals from a Markov chain is presented.
We propose a scheme in which, in contrast to the general settings of LERW, the loop-erasure is performed on a non-markovian sequence and moreover, not all loops are erased with necessity. We start with a special example of a random walk with loops, the number of which at every moment of time does not exceed a given fixed number. Further we consider loop-erased random walks, for which loops are erased at random moments of time that are hitting times for a Markov chain.
The asymptotics of the normalized length of such loop-erased walks is established.
We estimate also the speed of convergence of the normalized length of the loop-erased random walk on a finite group to the Rayleigh distribution.
Exit problems for Kou's process in a Markovian environment
Authors: Karnaukh Ie.
Published: October 2022

In this paper, we consider a path-wise sum of a Brownian motion plus a compound Poisson process
with exponentially distributed positive and negative jumps with parameters that depend on some finite Markov chain. Using
known fluctuation identities we investigate one-sided and two-sided
exit problems generalizing some results for Kou's processes to the
setting of regime switching models without exploiting the fluid embedding
technique. The generating function for the hitting time of the state-dependent
levels is analyzed. For the case of two states, the numerical examples
are given.
Multi-criteria decision analysis for evaluation of potential renewable energy resources in Malaysia

Switching to renewable energy resources as an alternative is critical for developing countries in order to ensure energy security and diversify their energy supply. Malaysia is endowed with biomass, solar, waste-to-energy, wind, and hydro energy potentials, although these have not been fully explored. This is because the country continues to rely extensively on conventional fossil-fuel energy sources such as coal and petroleum to generate power and consume energy. On the other hand, demand for energy is increasing as a result of population growth and a booming economy. Thus, this study intends to identify suitable potential renewable energy resources that can benefit Malaysia by analysing the outcomes of Focus Group Discussions (FGD) using the Analytic Hierarchy Process (AHP) as an analytical technique. Five renewable energy resources were evaluated: biomass, solar, waste to energy, wind, and hydro energy while five criteria were identified: carbon production, operational costs, location characteristics, energy, and availability of renewable energy resources. The outcome suggested a strategic focus on solar energy for Malaysia due to consideration in carbon production. This information will assist decision-makers in strategizing the most suitable renewable energy resources for Malaysia.
Notorious Neo-Nationalism: A Cultural-Studies Reading of Post-Imperial Anxiety, Cyber-Warfare, and Russia’s Return to Authoritarianism
Authors: Clowes Edith
Published: October 2022

In the 1990s polls showed that the majority of Russians hoped to live in a post-Soviet country governed not only by a strong state but by the genuine rule of law. What happened to make Russian public opinion turn—or seem to turn—in the course of a few short years toward what might be called an ultranationalist, and sometimes lawless, “make Russia great again” attitude? And why did the Russian leadership decide to start exporting those views and values to democratic countries? To answer these questions Professor Clowes’s article focuses on the rhetoric and actions of two prominent ultra-nationalist demagogues—Aleksandr Prokhanov and Aleksandr Dugin, whose blueprints anticipated and then promoted aspects of contemporary Russian geopolitics. Drawing from concepts of the “cultural archive” and “usable history,” she considers why ultraconservatism became dominant in Russia today. Finally, she comments on resonances, and in some cases interactions, with various ultraconservative groups in Europe and the United States.
Canadian Political Storytelling: Back to a Future?
Authors: Borins Sandford , Herst Beth
Published: October 2022

This paper examines English language or bilingual screen narratives (film and television series) dealing with the public sphere produced in Canada since 1960. Forty-nine texts were analysed including docudramas such as biopics about political leaders, documentaries, films on women in politics, and films on First Nations politics. Applying Borins and Herst’s four-quadrant model of political fables, most instantiate the heroic fable except films on women and First Nations. Conditions of production, including the influence of US films and television series, as well as the limitations of public-sector funding through the Canadian Broadcasting Corporation (CBC) and National Film Board (NFB) are also discussed. This paper illustrates how the evolving transnational entertainment economy constrains cultural producers working within traditional creative and industrial modes of production while simultaneously offering opportunities to invent (or reinvent) alternatives. The paper concludes that enhanced arm’s-length funding for documentaries represents the best way to ensure a vibrant future for this genre of narrative in Canada.

Published: October 2022

While operating upon the brain, deep seated lesions need to be approached by using retractor’s system, due to the soft and gelatinous nature of the brain. Using a conventional rigid, fixed retractor system for brain retraction appears harmful. As an alternative Thudicam Nasal Speculum (TNS) retractors can be used. This study was aimed to explore the outcome of TNS retractors in brain surgery. The cross-sectional study was conducted at Ziauddin University hospital north campus and National Medical Center Defense, Karachi, Pakistan, during a period between August 2019 to March 2020. A total of 60 patients were included (42 males and 18 females), with a median age of 25 years. In all these cases intra-cranial hematoma were removed with unremarkable damage, in aneurysm clipping it was found useful, without damaging adjacent areas and extraction of brain tumors was found to be very easy and non-damaging to the surrounding brain tissue. Patients had a follow-up period of about 03 months and contusion, ischemia or brain edema was not present in any patient. Only one patient died during second month after surgery due to Ischemic stroke of contra-lateral MCA. The study concludes that using TNS retractors was very helpful and non-damaging to the brain.

Small bowel obstruction secondary to gallstone ileus accounts for about 0.3% to 0.5 % of all patients with gallstone disease. Formation of primary intestinal stones causing obstruction and requiring laparotomy is very rare, and the presence of the diverticula adjacent to the stone precipitating in the stone formation is a rare phenomenon. A rare case of primary enterolith and jejunal diverticula is presented here. An older women presented with small bowel obstruction found to have dual pathology; operated for removal of stone and had uneventful recovery.

Authors: Oliveira Rosana Cavalcante de
Published: October 2022

Este estudo realiza o mapeamento dos investimentos no setor de hidrogênio, assim como identifica as principais rotas de produção de hidrogênio no Brasil com foco no hidrogênio sustentável, obtido a partir de fontes renováveis de energia ou utilizando o processo de captura, utilização e armazenamento de carbono (CCUS) para neutralizar as emissões. Os resultados identificados apontam que o Brasil já está recebendo grande volume de investimento em projetos para produção de hidrogênio, com destaque para os clusters industriais costeiros, que podem apoiar a adaptação da utilização da CCUS às usinas de hidrogênio existentes e possuem localização estratégica para exportação. Além disso, foram identificadas as principais políticas públicas realizadas para o setor de hidrogênio no Brasil, como o Projeto de Lei no 725/2022, que inclui o hidrogênio como fonte energética na matriz brasileira e estabelece metas para a inserção nos gasodutos nacionais, e o Decreto no 11.075, de 19 de maio de 2022, que criou o mercado regulado de carbono no Brasil.
