Schattenbanken und der Ausbau eines inklusiven Finanzwesens im globalen Süden
Authors: Jafri Juvaria
Published: October 2021

Finanzielle Inklusion ist eine Strategie zur Armutsbekämpfung, aber gleichzeitig ist es auch ein Symptom für zwei strukturelle Merkmale des globalen Finanzsystems: inländische Kreditbeschränkungen und Nachfrage von institutionellen Anlegern nach Rendite. Diese Merkmale wirken ungleich auf verschiedene geografische Räume und führen zur Notwendigkeit eines inklusiven Finanzwesens. Die Kreditschöpfung ist in Entwicklungsländern aufgrund des Inflationsdrucks, der sich aus der internationalen Währungshierarchie ergibt, eingeschränkt. Die Nachfrage nach Rendite ist eng mit der asymmetrischen Macht der wohlhabenden Länder zur Geld- und Kreditschöpfung verbunden. Der empirische Fall des inklusiven pakistanischen Finanzsektors, der sich zunehmend auf internationale Finanzströme stützt, zeigt auf, dass er ein Produkt von Hierarchien ist, die inländische Kreditbeschränkungen im Globalen Süden schaffen und Kapital aus dem Globalen Norden anziehen. Dies spiegelt sich in den Verbindungen zwischen finanzieller Inklusion und Schattenbankennetzwerken und -praktiken wider. Das Hauptargument dieses Beitrags ist, dass die Transformationen im pakistanischen Bankensektor – angetrieben durch die Notwendigkeit des Zugangs zu Finanzmitteln – durch inländische Kreditbeschränkungen und internationale Liquiditätsüberschüsse geprägt sind. Damit leistet der Artikel einen Beitrag zu zwei Strängen der heterodoxen ökonomischen Forschung: (1) der räumlichen Organisation von Geld- und Finanzflüssen und (2) der globalen Ungleichheit beim Zugang zu Finanzmitteln.
When and Where Is Transdisciplinary Engineering Applied in Projects? A Case Study
Authors: Kharlamov Alexander , Parry Glenn , Newnes Linda
Published: October 2021

Transdisciplinary engineering (TE) is gaining attention in academic literature and comes with the underlying assumption of being the next evolutionary step for incorporating engineering solutions in practice. We seek to answer the question of when TE is appropriate and what the conditions are for efficient applications of TE in practice. A framework for analysis is constructed integrating TE with theory of communication and strategic paradox. The framework is used as a lens in a single explorative case of an multi-university research project. The project brings together researchers from a diverse range of disciplines, working together to create a novel device that could have a transformative impact on specific cancer healthcare. Data is collected using structured interviews with project researchers. The main finding from the case study is that TE does not appear to be employed at all levels of abstraction. In this case TE is found to be employed at the strategic level, while tactical and operational levels adopt traditional approaches to working. Effective TE relies heavily on the relationship between specialisation and generalisation. We identify two main roles when it comes to people; specialists and generalists. Specialists (e.g. healthcare, pharmaceuticals & biotechnology) must be able to understand the general picture while the Generalists (e.g. business; operations) must be aware of the requirements and limitations of Specialists. Generalisations for practice and further research are discussed. The main contribution of the work is a framework for analysis of TE.
Predicting a Dry Bulk Freight Index by Deep Learning with Global Vessel Movement Data
Authors: Kanamoto Kei , Wada Yujiro , Shibasaki Ryuichi
Published: October 2021

The Baltic Dry Index (BDI) is an indicator of freight rates of dry bulk cargo. Since freight rate fluctuates widely with reflecting a rapid change in the shipping market, it is important for a shipping company to predict the BDI. In the shipping industry, detailed data on the movement of each vessel is currently available in the automated identification system (AIS) on board, and a wide use of the AIS data is increasingly expected. This study proposes a new prediction method for freight index using deep learning and AIS data. The prediction target is the Baltic Capesize Index (BCI) representing the freight rate index of a large dry-bulk carrier over 180,000 DWT. The AIS data and various statistics are incorporated into the model to predict the rise or fall of the BCI value after 30 days. A multiple set of AIS data of the entire world and several specific regions are used. Furthermore, the number of related statistics to be incorporated is increased and a method of selecting them by introducing maximal information coefficient is shown. From the simulation results, the prediction of BCI can be performed with a certain degree of accuracy. In addition, the effect of introducing AIS data in the BCI prediction is confirmed.

According with the exponential growth of Information Technology and current volatility world, the company has to drive uncertainty much rather than before. This is the time that keeping still shall result in termination of company. Therefore it is important to clarify the priority evaluation measure for continuing company operation, which we will define the vital power scale in this paper. Focusing working capital (Cash enable company to do legal payment to any stakeholders), which is essential to maintain company operation, evaluation measure for vital power of company (major measurable factor to evaluate working capital or practical measurable index for corporate management, corporate management is to enable to keep company alive) has been studied with TOC (Theory of constraints). Investigation has been done by using dice simulation having assumption of linkage and fluctuation in system, which is introduced by TOC, under the variable market price and varying company productivity.
Reliability-Base Performance Measure for Stochastic Networks
Authors: Song Wheyming Tina
Published: October 2021

An important performance measure for stochastic manufacturing networks is the system reliability, defined as the probability that the production output meets or exceeds a specified demand. This paper reviews and highlights the drawbacks of the previous works, including twenty one archival publications and the most recent published analytical Song rule. The major error in the twenty one archival publications error assumes that entities in the network are discrete and indivisible, while the analysis is based upon continuous flow through the network. That is, they assume that the number of defective items is a real number, instead of a random variable following a binomial distribution. We claim that the analytical approach in Song rule is valid for non-rework case, but is incorrect for general system reliability with reworking when the rework and non-rework path share the same capacity. This note corrects the mistakes in Song rule when the rework and non-rework path share the same capacity. The proposed analytical approach can be easily generalized to general system reliability with multiple reworks. The Song rule and the proposed corrected version of Song rule in this note are computationally inefficient and are only recommended as a validator instead of a problem solver. For big-scale system reliability, the simulation approach are recommended as the problem solver.
Integrating Knowledge Objects and Design Descriptions to Support Maintenance of Design Automation Systems
Authors: Poorkiany Morteza , Johansson Joel
Published: October 2021

Design automation systems are implemented by many manufacturing companies to automate the repetitive and time-consuming design tasks. By automating such tasks, the designers have more time to focus on creativity and offer more customized solutions to the customers. To automate a design task, first, the design knowledge should be captured from designers. This type of knowledge which is usually understandable by humans should be structured and formalized. Next, computer codes and scripts (that are mostly understandable by computers/expert persons) are created to execute the knowledge and provide the desired output. To support maintenance of computer codes and scripts in a design automation system, it is necessary to know what, how and why about that piece of code/script. In order to support maintenance of the systems, we represent the system’s knowledge in form of knowledge objects. Knowledge objects are executed in run time and consist of two parts: computer readable and human readable. The focus in this paper is on the human readable which we call it “design description”. A MOKA-based framework is provided to create design descriptions for the computer readable parts. The design descriptions help engineers to understand and if needed update the computer readable parts, which in a wider aspect support maintenance of the whole system. E-books were used as a way to represent the design descriptions and a case study is provided to explore the results of the research.
RESEARCH OF ECONOMIC PROCESSES BY THE METHODS OF DISCRETE GEOMETRY
Authors: Larysa Ivanova
Published: October 2021

The publication provides an analysis of the state of implementation and the effectiveness of the use of geometric methods of research and management of economic processes. The task of managing economic processes becomes extremely relevant in a decentralized (market) economy. Economic processes are complex and ambiguous. Many research and scientific works testify to the relevance and effectiveness of mathematical and geometric methods for analyzing economic processes and making decision in economic management.Management of economic processes in market conditions characterize by incomplete information and uncertainty. The system operates under random stochastic conditions. The law of variation of the parameters characterizes the process is first determined approximately based on the a priori dependence and refined over time. Thus, the task of forecasting and optimizing economic processes becomes urgent.Due to the complex type of mathematical objective functions that model the economic process, the sought solution should be consider a recommended characteristic. The final management decision made on the basis of practical experience as a result of expert analysis results probabilistic model and adjusted in accordance with the overall strategy for the development process. The use of geometric modeling methods, which distinguishes by their clarity and constructiveness, makes it possible to expand the capabilities of the apparatus for analyzing and predicting process changes. In addition, in geometry, as well as in economic processes, functions design and investigate on a finite interval of parameter changes, in contrast to unlimited abstract mathematical functions. The geometric interpretation of the probabilistic characteristics of the process determines a qualitatively new approach to finding a solution.It should be noted that for some reason: the discrete nature of data input-output, the presentation of design solutions, the compilation of calculation models, all models of economic processes should be considered discrete.The discrete nature of the models of processes in economics determines the relevance of using discrete geometry as a modeling tool.

COMPLEX VARIANT DESIGNIND OF MICROCLIMATE PARAMETERS OF ORTHODOX CHURCHES BY COMPUTER GEOMETRIC MEANS
Authors: Mykola Tereschuk
Published: October 2021

This work is devoted to the further development of the methodology for optimizing the microclimate parameters of orthodox churches by means of geometric modeling. The relevance of the chosen research topic is due, in particular, to the current tense situation with the COVID-19 pandemic. The proper sanitary and hygienic condition of public buildings is quite important for the preservation of people's health in modern conditions. This applies to various institutions of medicine, education, trade, nutrition, sports, culture, etc. Orthodox churches are no exception in this regard.It is well known that the parameters of the microclimate of the building depend on its geometric characteristics such as the area and volume of rooms, wall thickness, dimensions of window and door openings, etc. This is on the one hand. On the other hand, there is the dependence on the materials used for the construction, the selected heating, ventilation, air conditioning systems, etc. The external environment (air temperature, humidity, the presence of harmful substances, etc.) and the internal features of the building, for example, the number of people present in it, the duration and frequency of their stay, the activities carried out, etc. are also very significant. All this fully applies to orthodox churches.Due to the presence of certain material, financial and other restrictions that always exist during the construction of architectural structures and their further operation, it is essential to take into account the above aspects during the construction of new orthodox churches. The last mentioned processes are quite widespread in Ukraine now, what is due to the spiritual revival of the nation after decades of forced atheism.Thus, many factors, in particular, architectural space-planning solutions, selected building structures, heating, ventilation, air conditioning systems, etc., affect the microclimate of buildings. One of the ways of successful solution of the analyzed technical problem is the application of a complex variant design of the microclimate parameters of the rooms with the use of computer graphics. This approach is based on the fact that in the environment of the BIM (Building Information Modeling) technologies the central place is occupied by geometric model of the creating object, which combines the rest of its mathematical and other descriptions into one whole. Coverage of the outlined direction of scientific research on the example of orthodox churches is the main purpose of this publication.
DEVELOPMENT OF A MULTI-MODE ACCUMULATIVE MARKOV SYSTEM
Authors: Yuri Filonov  , Zoya Nagolkina
Published: October 2021

Systems are considered that earn a resource, monetary in the economic interpretation, and use it for functioning and accumulation. The conditions for the growth of savings are sought, which simultaneously ensure the non-positivity of the governing Markov chain. The widespread inhomogeneity of the phase space is essential. In the phase space (of a general type) of such a system, a nonnegative function , a function with values 1,2,…, , an irreducible homogeneous Markov chain , n = 0,1,… are given. The  values indicate the resource level of the system at time n, the  values indicate the mode, which is determined by the number of service locations, devices, service lines, the number of offices, workers, etc., the type of functioning as repair, prevention, downtime work. Let  be the average increments of ver the 1-st period for an arbitrary set набора  ,  states, is the probability of transition from the state  into mode  is the corresponding stochastic matrix, and  – is the stationary probability distribution for it. Let  be the value of  increased by the value  of an arbitrary function ψ (x)> 0, monotone and integrable on the interval [0, ∞). In a fairly general case, based on other of the authors' works, it is argued that the condition  for large X (w_i) is sufficient for the system to be acceptable in the sense that there is a convergence to 1 of the relative fraction of that time until the moment n, when the level X> C, (as n → ∞ with probability 1, for an arbitrarily large level C). That is, in a time relation that tends to 1, the functioning will take place in an ever better financial condition. Models are also considered that use the asymptotics and the model of deterioration of the system quality in a random way, but gradually, until unfavorable modes and the subsequent transition to the initial favorable mode, after the recovery mode, and further in a similar way. In this case, under the conditions of acceptability, it is not the stationary probabilities that are used, but the probabilities of system deterioration. It examines economic analogies with insurance and profitability.
THE OPTIMIZING APPROACH TO DETERMINATION THE PARAMETERS OF AN INACCESSIBLE POINT
Authors: Aleksandr Brailov  , Vitaliy Panchenko
Published: October 2021

In the present research the optimizing approach to the determination of the parameters of an inaccessible point of an object is developed. The common issues are revealed and essential steps of their resolution are identified.The essence of the problem is that the unavoidable contradiction between a need of obtaining the exact value of the determined parameter and an error involved in any measurement. The purpose of the present work is to develop in a complex three-dimensional geometrical and analytical models of the determination of the minimum domain (area, vicinity) of values of the parameters of an inaccessible point of an object.It is achieved in two steps: 1. Development of a three-dimensional geometrical model with crossed directional rays for contactless determination of the coordinates of an inaccessible point of an object under a given arrangement of the geodetic equipment. 2. Development of an optimizing analytical model for the determination of domain (area, vicinity) of values of parameters of an inaccessible point of an object according to the developed three-dimensional geometrical model with crossed directional rays. In the proposed optimizing approach, the three-dimensional geometrical model with crossed directional rays for the determination of coordinates of the inaccessible point of an object is developed. It is discussed that points С and C', coordinated of which to be determined, locates in domain [CDM, CEM], [C'D'M, C'E'M] of the minimum distance ρmin between crossed directional rays. The optimizing problem of the determination of coordinates of an inaccessible point of an object in space is reduced to a problem of the determination of the minimum distance between two crossed directional rays. It is shown that the problem has a unique solution if the directional rays are not parallel. It is discussed that mathematical finding of an extremum of function of the distance between two directional rays, and the discussed minimum, has real geometrical interpretation.It’s known from the theory of function of multiple variables that function ρ = f (tC'D', tC'E') reaches its extremum ρmin when its partial derivatives by each variable are equal to zero. Therefore, the system of the differential equations solved. The required point C' (xC', yC', zC') can be located, for example, in the middle of the minimum segment [C'D'M, C'E'M]. The proposed approach is verified using real experimental data.

Для полного анализа отобранных статей была использована онлайн-платформа (поиск в базах данных), с целью извлечения (название и назначение статей), организации (в табличной форме), суммирования информации и облегчения формирования базы данных. Результаты показали 35 опубликованных статей, но только 15 статей за последние пять лет имеют в качестве основной темы профилактику и риски преэклампсии в первичной медико-санитарной помощи. Сделан вывод о том, что основные направления, используемые не только медсестрами, но и всей командой, работающей в первичной медико-санитарной помощи, должны основываться на приветственном процессе, ориентированном на действия, которые могут быть определяющими в профилактике преэклампсии.

В статті наведено результати моніторингу діяльності будівельних підприємств України як інформаційно-аналітичної бази оцінювання їх економічної безпеки. Виступаючи своєрідним показником рівня розвитку економіки країни, будівельна галузь здатна виконувати функцію драйвера економічного зростання в цілому. Однак для цього перш за все необхідно забезпечити належний рівень економічної безпеки будівельних підприємств. За результатами проведеного аналітичного дослідження констатовано, що спостерігається тенденція до зростання за основними показниками-стимуляторами функціонування будівельних підприємств, але недостатніми темпами, щоб збільшити питому вагу галузі в структурі ВВП України. Також встановлено схожі тенденції показників по галузі у порівнянні з національним господарством, що свідчить про досить значну вразливість будівельних підприємств до зміни зовнішнього середовища і загрози їх економічній безпеці.

Project to Recover Prehispanic Textile Techniques in Peru: A brief review, from its initiation to today
Authors: Seo Yuki
Published: October 2021

I have lived in Peru for approximately 20 years, devoted to research and the study of prehispanic textiles. Because of the rich heritage and enormous quantity of tangible textile patrimony that exists in this country, I have chosen Peru to be able to pursue several interests. Over time, I worked in different museums, which motivated me to promote the study, understanding and recovery of prehispanic techniques. I proposed to give them life, so that they would be appreciated in these times. Along the way, I have met admirable self-taught persons who come from my country, Japan. This led me to a great challenge.

Each day new publications appear on prehispanic themes, and I must say that today there is considerably more information than there has been in the past; which permits us to learn and to know more about the Andean world. But we must clarify that, in general, they address theory, leaving practices aside.

Without being archaeologists or persons linked to academic discourse on these topics, these persons have achieved truly surprising results, reaching a very high level of skill in the reproduction of complex textiles. By their own initiative and with their own resources, they came to Peru to study, research, and achieve these reproductions. These ladies have the wisdom, competence and support of many decades of research, to be able to provide guidance and instruction on a scientific and academic level. Now, my principal task is to organize courses, in which we count on the valuable contribution of these ladies who are willing to transmit their knowledge, their enthusiasm and their admiration of these textiles with a passion like that of the prehispanic ancestors
Creating the Sensible: Weaving the Colonial Aesthetic at a Colonial Obraje
Authors: Smith Maria
Published: October 2021

When the Spanish arrived in the Andes, they encountered a rich textile production industry. The colonists quickly recognized the economic opportunity that skilled Andean weavers provided to colonists and in 1545 the first colonial obraje (textile mill) was established in Peru (Silva Santisteban 1964: 18). Roughly twenty-five years later Antonio de Oré established the Obraje de San Marcos de Chincheros outside the colonial city of Huamanga. There Indigenous and mestizo weavers produced textiles that were transported to Cusco to enter the global textile market. At the Obraje, forced Spanish techniques and technologies mixed with the Indigenous techniques and technologies that weavers brought with them into the Obraje. Over generations of weaving at the Obaje innovative techniques and technologies emerged as well. The textiles produced at the Obraje were amalgamations of these techniques and technologies, which went on to influence the larger colonial aesthetic. This placed the weavers in an important position of power as they influenced the sensible Colonial experience through their textiles (Ranciere 2010). In 2019 archaeological excavations were undertaken at the workshops and dormitories of the Obraje de San Marcos de Chincheros. The analysis of materials from the 2019 season field excavation provides significant evidence regarding the contributions that Colonial weavers at the Obraje de San Marcos de Chincheros made to the Colonial aesthetic. Weavers at the Obraje de San Marcos de Chincheros contributed to the colonial aesthetic and helped to define the Colonial-era, through their incorporation of Indigenous and European techniques and technologies alongside innovative techniques and technologies within their weavings.

Las hiperplasias cutáneas linfoides, antiguamente llamadas seudolinfomas cutáneos, son proliferaciones benignas de linfocitos, que simulan linfomas tanto clínica como histológicamente y de acuerdo a su componente celular más predominante puedenser clasificados como de células B o T. La de células B se considera una entidad clínicopatológica especifica, mientras que las de células T son un grupo heterogéneo de enfermedades, más que una enfermedad en sí. Dado que no son tan frecuentes no se tienen datos precisos de su epidemiología. Se presenta caso clínico de paciente de sexo femenino de 45 años con un nódulo eritematoso y violáceo en la región frontal de más de un año de evolución con reporte histopatológico confirmado por estudios de inmunohistoquímica de hiperplasia cutánea linfoide de células B.
