Análisis de los fondos de inversión y de pensiones en España: evolución y eficiencia en la gestión
Authors: Alda García Mercedes , Ferruz Agudo Luis , Reñé Ruth Vicente
Published: March 2023

Los fondos de inversión y los fondos de pensiones son los productos de inversión colectiva más importantes en España. Sin embargo, no deben confundirse entre sí ni tomarlos como equivalentes, ya que los segundos se caracterizan por ser un producto de ahorro a largo plazo cuya función es disponer de un capital adicional en el momento de la jubilación. Esta diferencia puede influir tanto en el inversor, al momento de decidirse por alguno de ellos, como en el gestor, que puede desarrollar diferentes estrategias de gestión. Por ello, en este trabajo se examinan las principales magnitudes de ambos mercados en España. Además, se analiza la eficiencia en la gestión de dos muestras de fondos españoles —una de fondos de inversión de renta variable global y otra de fondos de pensiones de renta variable—, con el objetivo de mostrar si sus gestiones son eficientes y si existen diferencias en ellas.
Prácticas organizativas saludables frente a la violencia en el trabajo. Estudio de su incidencia
Authors: Gimeno Navarro Miguel Ángel , Grandío Botella Antonio , Marqués Marzal Ana Isabel
Published: March 2023

La violencia en el trabajo es un problema creciente para las organizaciones pues conlleva importantes costes para la propia organización, sus miembros, y la comunidad. De sus diferentes dimensiones, la violencia organizativa es una de las menos investigadas. El presente estudio aporta evidencia sobre la relevancia que dicha dimensión tiene en el desarrollo de las conductas violentas en el trabajo. Los resultados obtenidos indican que las prácticas que implementa una organización inciden sobre los niveles de violencia que se dan en el trabajo. Para el desarrollo de organizaciones saludables, libres de violencia, la dirección de la empresa ha de adoptar un enfoque holístico y contemplar prácticas más relacionadas con la gestión de recursos humanos, que con factores de liderazgo o de diseño de puestos.

¿Cómo se mide el progreso en economía?
Authors: Zaratiegui Labiano Jesús María
Published: March 2023

La crisis económica mundial ha puesto, de nuevo, sobre la mesa el viejo tema de la capacidad explicativa de la cienciaeconómica. La visión convencional nos habla de un progreso lineal y progresivo en el tiempo, pero está claro que la economía presenta aún muchas limitaciones. ¿Cómo podemos medir ese progreso real o ficticio de la ciencia? ¿Se pueden considerar progreso los cambios en la teoría, y cómo? Hay diversas respuestas que no tienen por qué ser excluyentes. E este artículo, usamos el método de examinar cómo se ha respondido a las mismas preguntas en las ciencias naturales, el modelo que inspiró el nacimiento y posterior desarrollo de la economía. Además, se analiza cómo ha sido analizado, entendido y explicado el progreso en unas y otra. La claridad de los criterios de progreso en las ciencias naturales puede arrojar alguna luz sobre la misma cuestión en la ciencia económica.

(Ir) Relevância das contingências ambientais: uma investigação nas empresas brasileiras
Authors: Minatti Ferreira Denize Demarche , Borba José Alonso , Aguiar Da Rosa Carolina , Rodrigues Vicente Ernesto Fernando
Published: March 2023

As empresas enfrentam novos desafios no que diz respeito ao cumprimento de normas éticas, trabalhistas e ambientais. Para que se tenha reputação no aspecto social e ambiental é fundamental que se transmita transparência e confiabilidade nas ações. Deste modo, as empresas devem disponibilizar as informações exigidas por lei, mas que não se restrinjam ao que determina a norma; informações adicionais podem ser divulgadas objetivando transparência das demonstrações contábeis. Nesse sentido, o presente artigo teve por objetivo identificar a significância financeira dos valores das con- tingências passivas e provisões ambientais evidenciadas em 295 empresas que negociam suas ações na Bolsa de Valores, Mercadorias e Futuros - BM&FBovespa S.A. e que são consideradas potencialmente poluentes de acordo com legislação brasileira que dispõe sobre a Política Nacional do Meio Ambiente. Para identificar o quanto os passivos contingentes representam financeiramente para as empresas investigadas foi calculado o fator de significância a partir da divisão entre as contingências ambientais e provisões com o lucro líquido. Quanto ao impacto que as contingências causariam se todas tivessem sua probabilidade de ocorrência como provável e devessem ser provisionadas, observa-se que 25% das empresas teriam seus lucros reduzidos em mais da metade e até mesmo obteriam prejuízos. Por outro lado, cerca de metade das empresas possui uma significância de até 7% em relação ao lucro líquido, inferindose que a relevância das contingências passivas ambientais para maior parte das empresas é baixa se relacionadas ao lucro líquido das mesmas.
Efectos del cambio climático en la economía, el comercio internacional y la estrategia empresarial
Authors: Duarte Cueva Franklin
Published: March 2023

El impacto del cambio climático produce variaciones en la producción de bienes y servicios, modifica los patrones de consumo de los compradores, afecta las estrategias de los empresarios privados e influye en las políticas ambientales de los gobiernos. En este contexto, la rentabilidad esperada por los accionistas o socios puede no lograrse debido a factores incontrolables, que muchas veces generan amenazas u oportunidades para las empresas, según la industria en la que operen. Por otro lado, el comercio internacional es afectado por el cambio climático al aumentar las exigencias sanita- rias de parte de los gobiernos, las asociaciones de negocios retail y los consumidores. Esta situación conduce a redefinir estrategias de negocios y a la implementación de normas, por parte de organismos internacionales relacionados directa o indirectamente al cambio climático, en la búsqueda de adaptar o mitigar sus efectos sobre la vida en el planeta.

The role of tumor microenvironment in cholangiocarcinoma
Authors: Argenziano Maria Eva , Montori Michele , Scorzoni Chiara , Benedetti Antonio , Marzioni Marco , Maroni Luca
Published: March 2023

Cholangiocarcinoma (CCA) is an extremely aggressive neoplasia, mostly because of diagnostic delay and lack of effective therapies. CCA is typically surrounded by a peculiar microenvironment that includes abundant desmoplastic stroma and various cell types, which support and enhance CCA development. Among the tumor microenvironment (TME) cells, there are tumor infiltrating lymphocytes (TILs), such as CD8+ and CD4+ cells, Tregs, natural killers (NKs) and B lymphocytes. TILs contribute to an immunosuppressive microenvironment that leads to tumor immune escape. Dendritic cells (DCs) may lead to immunotolerance by maturation or antigen-presentation deficiency. Hepatic stellate cells (HSCs) are one of the major precursors of cancer-associated fibroblast (CAFs), which are distinguished in various subpopulations, each with different functions and interactions with other TME cells. CAFs can promote lymphangiogenesis, early lymph-node metastasis and proinflammatory environment, but they can also provide a physical and chemical barrier to protect CCA. Tumor-associated macrophages (TAMs) could be differentiated between two phenotypes, pro- and anti-inflammatory, and they may sustain invasiveness and immunosuppression. Myeloid-derived suppressor cells (MDSCs) impair cytotoxic T lymphocytes (CTLs) function, stimulating tumor proliferation and angiogenesis. Tumor-associated neutrophils (TANs) function is influenced by the TME, leading to tumor-suppressing or tumor-promoting functions. This paper aims to provide an overview of the CCA microenvironment cells, their role in tumor progression and possible correlated diagnostic, therapeutic and prognostic implications.
Роль інформаційного менеджменту у системі кризово-комунікаційного реагування
Authors: Киричок Андрій Петрович
Published: March 2023

У статті зазначено актуальність дослідження, яка полягає в тому, що без чітко структурованої інформаційної політики та контролю за процесами комунікації неможливе успішне державне управління, це пов’язано з тим, що від змістовного наповнення розповсюдження інформації залежить відношення населення не тільки до рішень та ініціатив органів державної влади, але й до тих чи інших подій у різних сферах життєдіяльності країни. Значення відмінно організованої системи комунікації підвищується в процесі кризових ситуацій у країні, коли знищуються стійкий рух інформації. У будь-яких кризових ситуаціях всі країни, які функціонують на демократичних засадах мають здійснювати контроль за інформаційним потоком. Метою дослідження є аналіз та обґрунтування ролі інформаційного менеджменту у системі кризово-комунікаційного реагування.
На основі проведеного дослідження проаналізовано наукові підходи до визначення поняття «інформаційний менеджмент».
Визначено, що основними компонентами успішного інформаційного менеджменту у системі кризово-комунікаційного реагування є оперативне і узгоджене розповсюдження інформації про кризову ситуацію за допомогою засобів масової інформації, врахування основних потреб та інтересів громадян, підкорення довіри людей через створення іміджу чесності, прозорості, рішучості, прояву турботи, переконання у результативності заходів стосовно вирішення кризової ситуації.
Сформовані висновки, що успішне кризово-комунікаційне реагування організації передбачає узгоджені дії з інформаційного менеджменту і постійне інформування кожного, до яких відноситься криза, а також, насамперед до засобів масової інформації. Крім того, відповідно до проведеного аналізу наукових поглядів зарубіжних вчених було визначено, що сутність кризово-комунікаційного реагування розглядаються як повідомлення організації про власні дії населення в процесі кризи.
Візуальний контент у соціальних мережах
Authors: Тріщук Руслан Любомирович , Войтюк Тетяна Олександрівна
Published: March 2023

Схарактеризовано види візуалізації, які використовують у різних соціальних мережах, зокрема фото, ілюстрації (комікси, меми, художні картини, карикатури тощо), інфографіку (карти, таблиці, графіки, схеми, діаграми, тощо) і різні форми мультимедійного контенту, як-от відеоролики, gif-анімацію тощо, та їх вплив на цільову авдиторію. Якісний візуальний контент суттєво спрощує та пришвидшує сприймання складної інформації, яку зручно переглядати на будь-якому пристрої та за різних умов сприйняття. Зазначено, що ефективність того чи іншого виду візуального контенту безпосередньо залежить від інтересів користувачів та формату комунікаційної платформи. Для кожної соціальної мережі діють свої правила, тому необхідно зважати на те, що візуальні інструменти не є універсальними, тобто вони успішно виконують свої функції лише за певних умов. Зроблено висновок, що специфіка поширення візуальних елементів залежить від інтересів цільової аудиторії та від технічних характеристик соціальної мережі. Найпопулярнішими візуальними технологіями в соціальних мережах є фото та відео. Вони впливають на емоції користувачів, створюють атмосферу довкола основної новини та загалом підвищують загальний рейтинг медіа. За допомогою цих інструментів користувач почувається безпосереднім учасником подій. У соціальних мережах, як і в будь-якому медіа, фотографічні зображення мають бути якісними, адже від сюжетно-композиційної та технічної якості фотознімків безпосередньо залежить і кількість переглядів того чи іншого матеріалу та відвідуваність інформаційного ресурсу в цілому. Візуалізація в інформаційному повідомлені буває ефективною лише в тому разі, якщо на початковому етапі було чітко визначено її мету і завдання, проаналізовано дані стосовно цільової аудиторії та обрано правильний інструмент наочного представлення. Запорукою активного впливу на сприйняття відеоконтенту аудиторією є здатність коректно добирати відеоролики, адже вони дозволяють маніпулювати емоціями сильніше ніж фотосюжети в добірках.

Published: March 2023

Livability is one of the paramount characteristics of the current era that architects striving to achieve. This situation becomes even more important on commercial streets, whose functional diversity and constant movement of people require special action. In Erbil, commercial streets suffer from neglect in terms of adopting places for livability. Although it has huge potential to form an attractive and entertaining environment other than shopping. Some countries have developed standards for the design of commercial streets. The basic requirements are the same, but details usually vary according to the diverse needs of people. The research aims to identify a comprehensive framework (A Checklist) for placemaking to form the basis for measuring livability in one of the vital streets in Erbil city. This Framework is considered the basis for assessing and designing at the same time, supporting designers to achieve two main pillars: develop existing streets and suggest basic principles for future street design. This article adopts a practical framework, a questionnaire, a field survey, and observation as research methods. The research concluded that altogether placemaking dimensions are essential in activating livability, and a sort of balance between the main dimensions appeared. The more applied strategies, the higher the street livability.
The Presence of the Defense Lawyer in Vietnam’s Criminal Justice System: Substantive or Cosmetic?
Authors: Chi Le Lan , Lan Nguyen Thi , Ngan Nguyen Hoang
Published: March 2023

Defense lawyers play an important role in protecting the rights and interests of the accused, contributing to upholding justice and reducing the number of wrongful convictions. In Vietnam, in accordance with the current Criminal Procedure Code of 2015, defense lawyers have been given more and more rights to perform legal defense activities. However, defense lawyers are still considered to bepassive participants in criminal proceedings, classified under the “judicial complementary” group. The right of lawyers to collect evidence is restricted. Furthermore, other rights have not been fully implemented. The number of lawyers compared to the entire population remains low, and there are very few criminal cases that include the participation of defense lawyers. These circumstances beg the question of whether the presence of defense lawyers in Vietnam’s criminal justice system is substantive or merely a cosmetic façade intended to improve Vietnam’s global image. This paper seeks to answer this question by analyzing the results of surveys conducted with Vietnamese lawyers. Moreover, it provides some recommendations to strengthen the role of defense lawyers in the criminal justice system of Vietnam.

Published: March 2023

The high rate of deforestation and many forest disputes in Indonesia show that forest management in Indonesia is not based on the principles of good forest governance. It also shows that there is still a lack of attention to the aspect of sustainable forest development which focuses on a balanced sustainability condition between the three forest functions (production, ecology, and socio-economic functions). Geospatial Information is expected to be the solution to help provide an accurate data and information which mapping forest development in accordance with the conditions of each forest area, so that the three functions can operate coherently. Furthermore, with the presence of integrated geospatial data, it can be used as a tool in policy formulation, decision making, and/or dispute resolution in the forestry sector. This paper applies empirical juridical research consisting participatory methods through discussions and interviews with related parties.  In practice, the legal materials are firstly collected by using inventory and documentation. Then, it’s completed by interviews and Focus Group Discussion data. Moreover, it also applies statutory, conceptual, and case approaches. This paper highlights the use of geospatial information data in the forestry legislation making in Indonesia.  Hence, this paper will present new information about the model of forestry dispute resolution based on geospatial information.
INFLUENCE ANALYSIS OF THE DIFFERENT TYPES BUS BODY COMPOSITION ON THE CHARACTERISTICS OF THE AIR FLOWS FORMATION IN CONDITIONS OF FORCED CABIN CONVECTION
Authors: Holenko Kostyantyn , Voichyshyn Yurii , Yakovenko Yevheniia , Horbay Orest , Rudyk Oleksandr
Published: March 2023

The paper proposes the influence analysis of five types of city bus body layouts on the air flows formation in the cabin, generated by the motor compartment fan under conditions of forced convection. The authors conducted three types of tests with different boundary conditions in the finite element calculation module of ANSYS Fluent: the input velocity of the flows from the motor compartment fan, the temperature of the flows and the environment, internal and external convection. According to the results of simulated field tests, it was established that the most effective is the layout of the bus with the engine located horizontally in the rear overhang. Such a layout is relatively expensive from the point of view of production, because it requires the installation of the opposite type of "boxer" engine in most cases, which is characterized by a higher cost, complexity of maintenance and is less common in contrast to V-type internal combustion engine schemes. However, air circulation occurs throughout the cabin the most effectively in this layout scheme, taking into account the driver's cabin and other locations. Layouts with central positioning of the engine (vertical and horizontal) also deserve attention - they ensure a symmetrical distribution of air in the front and rear of the bus body, which can be especially relevant in the cold period of the year.
EVALUATION OF THE STABILITY OF A TWO-AXLE WHEELED MACHINE WHEN SLIDDING DURING THE BRAKING PROCESS
Authors: Zakapko Оlexander
Published: March 2023

One of the common causes of road traffic accidents is the skidding of the car during braking with the rear wheels locking in advance. It was determined that the cause of the car skidding is the anticipatory blocking of the rear wheels of the car. However when building dynamic and mathematical models the degree of excessive braking of the rear wheels wasn't taken into account. The conducted research made it possible to obtain analytical expressions for estimating the steady speed of the car when braking with locked rear and unlocked front wheels at different degrees of underutilization of the coupling weight on the front axle. A new indicator has been introduced – the degree of underutilization of the car's hitch weight when the rear axle skids. The goal of the study is to improve the accuracy of the evaluation of the car's indicators when braking with the front non-locked and rear locked wheels by improving the method of determining the total reaction of the road on the rear wheels. To achieve the goal, the task of determining the total reaction of the road on the rear wheels was solved. As a result of the conducted research, analytical expressions were obtained for estimating the steady speed of the car when braking with locked rear and unlocked front wheels at different degrees of underutilization of the coupling weight on the front axle. In the obtained analytical expressions, a new indicator is used – the degree of underutilization of the towing weight of the car

Authors: Kalinin Evgeny , Lebedev Sergii , Kozhushko Andrii , Koliesnik Ivan
Published: March 2023

The paper analyzes the influence of the geometric parameters of the semi-trailer unit on the stability of its movement. A mathematical model of the dynamics of the cultivator unit under the influence of disturbing forces is developed. The analysis of research results shows that in the process of movement, the wheeled semi-trailer unit is subjected to transverse forces, which arise as a result of the unevenness of the traction resistance of the side and rear beams. The main vector and the main moment cause the unit to deviate from the rectilinear movement. The differential equations obtained in the work make it possible to determine the values of the lead angles, their components, and the speed at which the lead of the unit will be the smallest. Based on the dependence of the angle of departure of the unit on the disturbing forces and speed of movement, the optimal location of the side bars of the semi-trailer unit on the tractor frame was found.

Published: March 2023

The need to control fuel consumption during vehicle operation is considered. The analysis of analytical methods for assessing the fuel efficiency of vehicles is presented. The current in Ukraine norms of rationing of fuel consumption are analyzed. The main disadvantages of accounting for fuels and lubricants in our country and in other countries are indicated. A statistical assessment of fuel consumption indicators was carried out according to the methodology of the Ministry of Infrastructure of Ukraine. The graphical dependences of the distribution of fuel consumption for the main groups of cars, sawn out according to the data of regulatory and legal information, are obtained. A regression assessment of the relationship between fuel consumption and the main technical parameters of a vehicle has been performed. The parameters for a mathematical model for calculating fuel consumption for the main groups of vehicles in the agricultural sector are obtained - these are dump trucks and truck tractors. The adequacy of the model, the quality of the parameters, and the confidence interval of the domain of determination are assessed. It is proposed to combine several methods for standardizing fuel consumption, which will allow setting the standard value by a calculation method. An assessment was made of the consistency of the obtained regression model with the data that were obtained using the methodology that is used in KhNADU to calculate the base rate of fuel consumption. Comparison of fuel consumption rates obtained by different methods is given. An algorithm for the use of a regression model for the method of accounting for the consumption of fuels and lubricants at road transport enterprises has been developed. Conclusions are formulated and the ways of further research aimed at improving the methodology for standardizing fuel consumption in our country are indicated.

Published: March 2023

Research relevance When performing reconnaissance missions, a UAV system primarily conducts surveillance of the target area, locates stationary or moving enemy targets, determines their coordinates or transmits their images directly to the command post. Directing artillery fire as well as guiding missiles or carrying out target designation (illumination of targets) for high-precision weapons, automatic determination of target coordinates and their prompt transmission to the appropriate ground stations is essential. This article provides a mathematical solution to the issue of determining the motion parameters of a target spotted during surveillance of an area by a reconnaissance drone (UAV). The subject of the study in the article is UAV- rocket-artillery systems. The purpose of the work is to develop a mathematical model for determining the parameters of the target's movement using a UAV. The following tasks are solved in the article: to develop target positioning diagram; to develop a mathematical model for determining the parameters of the target's movement.  The methods used in the article are the methods of mathematical modelling. The following results were obtained: а target positioning scheme has been compiled to determine the coordinates and movement parameters; a mathematical dependence has been developed to determine the coordinates of a fixed target; a mathematical model has been developed to determine the parameters of the target's movement. Conclusions: by calculating the current coordinates of a moving target using the method proposed in this paper, it is possible to determine the coordinates of the target and parameters of the target's movement, including the direction of movement and the trajectory.

Authors: Havrashenko Anton , Barkovska Olesia
Published: March 2023

The work is devoted to the development of an organizational model of the machine translation system of artificial languages. The main goal is the analysis of text augmentation algorithms, which are significant elements of the developed machine translation system at the stage of improvement of new dictionaries created on the basis of already existing dictionaries. In the course of the work was developed a model of the machine translation system, created dictionaries based on texts and based on already existing dictionaries using augmentation methods such as back translation and crossover; improved dictionary based on algorithms of n-grams, Knuth-Morris-Pratt and word search in the text (such as binary search, tree search, sqrt decomposition). In addition, the work implements the possibility of using the prepared dictionary for translation. Obtained results can improve existing systems of machine translation of the text of artificial languages. Practical significance of this work is the analysis and improvement of text augmentation algorithms by changing the prefix tree type. Compared to the conventional algorithm, the improved algorithm reduced the memory usage by almost 13 times, which allows it to be used on much larger test data. This was achieved by changing the internal system of the node of the prefix tree from constant references to an expandable list.
THE USE OF CORRELATION ANALYSIS IN ASSESSING THE UNCERTAINTY OF THE INFLUENCE OF EXTERNAL FACTORS ON THE RESULT OF THERMAL CONTROL OF BIOLOGICAL OBJECTS
Authors: Hryhorenko Ihor , Hryhorenko Svіtlana , Zhuk Oleksandr
Published: March 2023

Research task. The paper considers the solution of the scientific and practical problem of determining the influence of external factors on the result of non-contact thermal control of biological objects. Object of study. A human was chosen as a biological object. Research progress. Establishing the correlation dependence was carried out in the two most opposite seasons in terms of climate parameters – winter and summer. One person was taken for the study, whose temperature was measured using a FLIR Vue Pro R 640 thermal imager mounted on a Cheerson CX-20 quadcopter at one-hour intervals throughout the day. The data were obtained in the summer period on August 10, 2022. In the winter period, measurements were carried out on January 20, 2022. Research results. Conclusions were made about the absence of a linear correlation between humidity, air temperature and body temperature of BO in the summer period. On the contrary, a high correlation was established between all the indicated parameters in the winter period. Conclusions were made about the need to develop a mathematical model of the factor influence on the thermal control result of the BO in order to obtain analytical ratios for evaluating the quantitative information on each of the temperature control indicators under the factor influence on the conversion function of these indicators. It is noted that such a model will make it possible to rank the indicators of temperature control according to the decrease in their sensitivity to changes in the levels of the temperature control parameter. Usage suggestions. It is proposed to calculate the correcting coefficients to determine the exact value of the body temperature, because it was experimentally established that the values of the body temperature in the winter period differ from the actual values precisely due to the influence of the temperature of the external environment.

Published: March 2023

Purpose of work. Development of proposals for desirability function calculation by interval arithmetic method. Obtained results. A connection was shown between multiple-criterial (vector) optimization problem and calculation of Harrington function (desirability function) values. Generalized desirability function was shown to be treated as a multiplicative convolution of partial desirabilities. Using golden section properties, a connection was discerned between hierarchy analysis methods and calculation of desirability function values. In this case the distribution of probable desirability function values among intervals determined in accordance with golden mean rule does coincide with values obtained by expert method. Application of golden proportion enables increasing the number of intervals; thus, it may prove convenient in improvement of Harrington function sensitivity. Conclusions. For partial desirability function in its explicit form such geometric characteristics were determined as values of tangent, curvature of curve and center of curvature coordinates. For a necessary averaged desirability system obtaining process control, such characteristics were determined in general and explicit form as partial desirability elasticity, generalized desirability elasticity relative to partial desirability, generalized desirability elasticity relative to a variable that has physical sense and respective dimension depending on particular subject area and affects partial desirability value. To determine the boundary value of one partial desirability being substituted for another partial desirability, the rate of substitution function and boundary rate of substitution elasticity function were established. Due to errors emerging in determination of desirability function values application of interval analysis methods was proposed. Application of interval numbers as presented in hyperbolic form was shown for calcutaion of partial and generalized desirability, A partial power series sum was determined relative to a variable presented in hyperbolic form. Suggestions. The method of calculation of Harrington function (desirability function) values at interval determination of arguments was shown to be eventually used in development of specifications and preliminary design of complicated engineering аnd organizational systems.

The domestic dog (Canis familiaris) is the most popular human companion, also in Poland. Among recognized by FCI dog breeds, there are those that are more popular. In order to meet the needs of owners and their dogs, dog-parks were created. Sometimes they are controversial. The aim of monitoring is to determine the population of dogs in the study area and to evaluate the dogparks and their use by dog owners. 14 places were selected for monitoring in the Mokotów district: 6 dog-parks and 8 parks. The respondents to the survey were dog keepers and owners. A survey was conducted for dog owners in Warsaw and active monitoring of parks, green spaces and dog-park in the Mokotów district. The survey results showed that the most frequently owning type of dog is the Mongrel. The vast majority of respondents declare that they do not use dog-parks. The results of active monitoring of the dog population also showed that the most frequently owned type of dog is the Mongrel. From purebred dogs, sequentially: Yorkshire Terrier, Jack Russell Terrier, Labrador Retriever, next Golden Retriever. Parks for dogs in the Mokotów district are fenced or designated spaces, enriched with equipment that activates caregivers and their pets. 2 of the 6 dog-areas selected for observation have been permanently removed. Both facilities were located in a residential area. Dog-parks are most often used as places for free explorations of dogs, without leash. In most of the observations, no dog-owner activity was observed.

Published: March 2023

Understanding the wave parameters in the ocean wave phenomenon is necessary to learn and develop the potential of ocean wave energy. Therefore, this study created a simple laboratory-scale of wave simulator that was developed using an electric motor. The various wave parameters obtained by different treatments were carried out using variations in the angle of the wedge inclination and the rotational speed of the wave generator. In this system, two pulleys of different sizes were used, a large pulley with a diameter of 20 cm and a small pulley with a diameter varying between 1.25 cm and 1.98 cm. Changing the size of the pulleys uses the principle of axial rotational motion to produce different rotational speeds. Moreover, the video tracker analysis application was used to characterize the parameters of the waves generated in the simulator that has been designed. The parameters obtained include wave height, amplitude, frequency, wave period, wavelength, and wave propagation speed. In the examination and analysis that have been carried out, it has been found that increasing wave height and amplitude correlates with increasing the inclination of wedges. The frequency and speed of the waves are linearly related to changes in the rotation speed of the wave generator. For the characteristic wavelength, there is inverse relation to the rotational speed. Based on this study, the wave simulator system and video tracking analysis application can be used to increase the understanding of wave parameters. In addition, this research can also be used as preliminary research on developing a prototype for an ocean wave energy converter on the laboratory scale.

Shallow geothermal technology, opportunities in cold regions, and related data for deployment at Fort Wainwright
Authors: Zody Zachary , Gisladottir Viktoria
Published: March 2023

The DoD considers improving Arctic capabilities critical (DoD 2019; HQDA 2021). Deployment of shallow geothermal energy systems at cold regions installations provides opportunity to increase thermal energy resilience by lessening dependence on fuel supply and supporting installations’ NetZero transitions. Deployment can be leveraged across facilities, for ex-ample using Fort Wainwright metrics for implementation of geothermal in cold region bases. Fort Wainwright is an extreme case of heating dominant loads owing to harsh conditions in Alaska, making it ideal for proving feasibility in most heating dominant installations. Proven feasibility and potential mass deployment will help reduce emissions and increase resilience across the DoD cold region network. This report introduces the shallow geothermal energy and storage technology combination that would best fit demonstration in Alaska. Focus is on leveraging shallow, low-temperature geothermal for the development of a larger geothermal district heating and cooling (GDHC) system with underground thermal energy storage (UTES) and geothermal heat exchangers (GHX). Such systems are proven in cooling dominant climates, and individual components are proven in heating dominant climates, but deployment of a larger system in a heating dominant climate is not well established. Deployment at Fort Wainwright would represent an improvement in the technology.
Textiles in seventeenth and eighteenth-century Styria (Austria): Innovation and distribution
Authors: Pöttler Burkhard
Published: March 2023

The focus of this paper lies on the inhabitants of the duchy of Styria, those from small towns, market towns and the capital Graz, as well as those from rural dominions. Special stress is laid on local merchants as distributors of fabrics and final products. Their probate inventories allow us to get at least some insights into the locally available products and they often are regarded as best source for the research in changes of consumer habits. Cotton and silk are important indicators of these changes. The article is based on probate inventories covering mainly the period from about 1660 to about 1790 with some earlier as well as some later examples. The core of the research database comes from nearly 1,140 probate inventories from the monastery of Seckau, and about 110 from the city of Graz, another 234 from other Styrian towns, market towns, and dominions. Despite the relatively large number of sources, the contribution follows a historical-anthropological approach.
Vehicle Detection in Low Illumination Based on Attention Mechanism and RetinexNet
Authors: Qu Rongdan , Li Xingke
Published: March 2023

This study proposes a method to detect vehicles by enhancing the YOLOv5 network 1
structure and incorporating RetinexNet to address the problem of limited detection capabilities of 2
target identification algorithms in low illumination conditions, such as at night time. CBAM attention 3
module is implemented in the network’s Neck detection layer to extract the vehicle’s primary features, 4
reduce the extraction of unused features, and improve the vehicle’s detection performance. The 5
DIoU is introduced as the loss function of the model to solve the imprecise location of the prediction 6
box and speed up the convergence of the model. RetinexNet is applied to enhance the detection 7
capabilities of low-illumination images by enhancing and denoising them. The experimental results 8
indicate that the enhanced model detects vehicles with 90% accuracy in low-light conditions and has 9
a strong detection performance overall.

Published: March 2023

Background
ADRD underdiagnosis among minority populations is well-established and known to be more prevalent among women. Yet, it remains unclear if these patterns exist among Middle Eastern and North African (MENA) adults. We estimated ADRD underdiagnosis among MENA and other US- and foreign-born non-Hispanic Whites and compared sex-stratified results.
Methods
We linked 2000–2017 National Health Interview Survey and 2001–2018 Medical Expenditure Panel Survey data (ages > = 65 years, n = 23,981). Undiagnosed ADRD was suspected if participants reported cognitive limitations without corresponding ADRD diagnosis.
Results
Undiagnosed ADRD was highest among MENA adults (15.8%) compared to non-Hispanic Whites (US-born = 8.1%; foreign-born = 11.8%). MENA women had 2.52 times greater odds (95% CI = 1.31–4.84) of undiagnosed ADRD compared to US-born White women after adjusting for risk factors.
Discussion
This study contributes the first national estimates of undiagnosed ADRD among MENA adults. Continued research is needed to facilitate policy changes that more comprehensively address health disparities and related resource allocation.
