Published: October 2023

Regional practices for protection the rights of indigenous peoples are the issue that requires reflection in line with the state ethno-national policy of modern federal states and in particular – the subjects of the Arctic zone of the Russian Federation (AZRF).The purpose of the study is built around identifying the existing areas of regional systems for protecting the rights of indigenous peoples in the field of public administration. Based on this goal, the authors identify the tasks related to the doctrine of a regional system for protection the rights of indigenous peoples, determining the basic elements of these regional systems through the case study of the Russian Arctic and comparing common features of these systems with the goals of sustainable development. The solution of these tasks was based on the Russian federal legislation analysis, regulatory and legal acts of the Russian Arctic regions, as well as relevant scientific literature. The analysis led to the conclusion that the regional system for protecting the rights of indigenous peoples as a regional institutional and legal model varies depending on the specificity of each region, their distinctive features and process of development.By monitoring the current regional legislation and the law enforcement and management practices, the main elements of this system were identified.The goals of the regional systems for protecting the rights of indigenous peoples in the Russian Arctic coincide with the sustainable development goals defined by the UN, including the fight against poverty, infrastructure development, responsible consumption and production. The theoretical and practical significance of the study lies in the generalization of regional experience in the field of protecting the rights of indigenous peoples, as well as the development of a doctrinal definition of a regional system for protecting the rights of indigenous peoples.
WHAT GLOBAL COMPOSITE INDEXES CAN TELL ABOUT INNOVATION CLIMATE IN RUSSIA
Authors:   National Research University Higher School of Economics, Vlasova Valeriya
Published: October 2023

The article presents a review of approaches to assessing the business climate for innovation. Composite indexes are considered the main tool for comprehensive monitoring of a wide range of external environment factors that determine the favorability of the business climate for innovation. The paper discusses the opportunities and limitations of analyzing the innovation climate using international rankings; and formulates the main requirements for such projects for targeted use to analyze national innovation systems and improve state regulation of innovation. The paper identifies and analyzes 16 international projects that indirectly or directly provide an aggregated country-level assessment of the conditions and (or) results of innovation activities. It is shown that the approaches of indexes developers to determine the innovation climate often have no theoretical justification, and only some of the projects are characterized by publicly verifiable methodology, sustainability of assessments and transparency of initial data. The Global Innovation Index, which satisfies most of the formulated criteria, stands out in this row. Based on the Global Innovation Index example, the empirical part of the article uses its longitudinal data for 2017-2021 to identify strengths and weaknesses of the national innovation system of Russia, taking into account benchmarking of development dynamics across a wide range of countries covered by the harmonized observation. The obtained results reflect the analytical potential of international innovation rankings, as well as allow identifying factors which may contribute to or hinder the achievement of the global innovation leadership and formulating policy recommendations.
DIGITAL TRANSFORMATION OF PUBLIC ADMINISTRATION: UNITY OF SERVICE DIGITAL AND SOCIAL NETWORK ASPECTS
Authors:   Moscow Institute of Physics and Technology (National Research University), Zotov Vitaly , Vasilenko Lyudmila ,   Russian Presidential Academy of National Economy and Public Administration
Published: October 2023

The article reveals prospects of digitalization of public administration at the level of theoretical and methodological reflection and practical implementation. Analyzing modern public governance concepts ranging from participatory management to smart supervision, the authors conclude that, in the context of socio-technical convergence, public administration should combine the use of algorithmic control with the task of consolidating interests of stakeholders. The promotion of the concept will be determined by the stakeholder’s assessment of the role played by state digital platforms in public governance transformation. In 2021, a survey of experts was conducted to assess two aspects of their development: digital (involving the use of big data and algorithmic control) and network (based on the participation of citizens in the working-out, decision-making and implementation processes). The survey showed that authorities' use of state digital platforms to respond effectively to individual citizens' needs should be accompanied by involving them in solving socially significant problems. Therefore, the co-evolution of digital and network aspects of the functioning of public digital platforms becomes extremely important. Public decision-making should be developed in order to correct the technological bias in the digitization of public and municipal administration. The technological dimension of the digitization of public and municipal governance can be corrected through the development of public decision-making via digital platforms. And to do that, it is necessary to address the problem of stimulating activity of both officials and citizens, to increase the level of trust in the authorities.
HOUSING VOUCHERS FOR CARE LEAVERS IN RUSSIA: OPPORTUNITIES AND BARRIERS IN THE REGULATORY FRAMEWORK FOR THEIR EFFECTIVE IMPLEMENTATION
Authors:   National Research University Higher School of Economics, Gorina Elena , Kosinova Liubov ,   National Research University Higher School of Economics
Published: October 2023

For a decade the public authorities in Russia have been failing to fulfill its obligations to young care leavers. The long-term waiting list for public housing is an acute problem of social policy in the country that requires new tools to be solved. Housing vouchers, or lump-sum social payments for the purchase of residential property, at the expense of the Russian regions’ budgets, are supposed to be one of them. The paper aims to evaluate the legal framework of the housing vouchers program from the perspective of opportunities and barriers it has for eliminating the problem. The study used data from the relevant laws and regulations covering all regions, where the housing vouchers were established from 2019 to 2023. The concept of performance-oriented social program and key factors influencing the access to public benefits constitute our theoretical framework. Within it, we examine the range of terms and conditions that should be met by applicants to successfully buy residential properties by means of the housing vouchers. Our findings show that the regulations concerning customer focus, providing lower thresholds for applicants, promoting awareness about the program and its entitlement criteria, and shortening the duration of administrative procedures are likely to contribute to the increase of program performance. On the contrary, barriers that prevent obtaining proper results are due to high transaction costs of claiming support, low purchasing power of payments in the housing market, tight restrictions on how recipients should dispose funds and excessively strict eligibility criteria.

Published: October 2023

Addressing regional problems in the field of environmental protection is carried out within the framework of targeted environmental programs, documents reflecting the essence of the ongoing regional environmental policy. Approved indicators monitor the effectiveness of its implementation. In many regions, the results of the implementation of previous programs are disappointing, which is due to many reasons. The following questions remain unanswered: how the national and territorial interests are combined in the development of programs, how the content of the program tasks and the indicators of their effectiveness correspond to the targets of these documents? The hypothesis of the study is that the imperfection of regional environmental programs complicates their effectiveness. The purpose of the study is to analyze the content of the used indicators that are fixed in the environmental programs of the most economically developed regions of the Far Eastfor identification of the highest priority regional environmental tasks and the focus of their solution to improve the system of indicators in subsequent revisions of environmental protection documents. The information base includes regulatory documents in the field of environmental security in Russia, statistics data, rules and regulations on the development, implementation and evaluation of effectiveness state and municipal programs, national and regional programs on "Environmental protection" of the Far East subjects, adopted for the period 2020-2025. Having analysed 211 indicators proposed in the regional programs in order to determine the share of the most significant for environmental protection, the correlation of their content with the specifics of regional development has been established. It has been determined that more than 50% of all indicators relate to direct improvement of the environment. During the analysis, the main shortcomings in the selection of the indicators have been identified: 16% of indicators are not correct in content; 41% of indicators do not have clear quantitative benchmarks, which does not always make it possible to assess the achievement of objectives. The solution of the indicated issues will allow expanding the theoretical knowledge in terms of the formation of regional environmental policy and enriching the practice of regional interpretation and solution of accumulated problems, which is demanded due to the limited number of works in this area.

EVOLUTION OF THE BRAZILIAN PUBLIC ADMINISTRATION
Authors:   Institute for Global Public Policy (IGPP) Fudan University, Puppim de Oliveira Jose A.
Published: October 2023

This manuscript analyzes the changes in Brazilian public administration over the years and the attempts to reform and improve the effectiveness of the delivery of public services. There are three main modes of operation in the Brazilian public administration:patrimonialism, bureaucratic and managerial. Even though reforms have taken some effect over the decades, all three modes subsist in different forms in the public organizations. After the democratization of the country, there has been a decentralization process and a growing influence of civil society on public affairs, but accountability is still low. Reforms were carried out by authoritarian and democratic governments from different political spectrums, but the quality of public administration and governance still suffers from ineffectiveness in the delivery of public services and patrimonialism, resulting in many cases of corruption and mismanagement. The worsening of the financial situation of the country tends to aggravate the situation in the future.
ADMINISTRATIVE AND CIVIL SERVICE REFORMS IN RUSSIA: RECENT TRENDS AT THE TIME OF TURBULENCE
Authors:   National Research University Higher School of Economics, Barabashev Alexey , Klimenko Andrey ,   National Research University Higher School of Economics
Published: October 2023

The article examines the changes in governance that have taken place in Russia since 2019, with a particular focus on the impact of the COVID-19 pandemic (which persisted until early 2022) and the ongoing military operation in Ukraine (which began in February 2022). The article discusses the specific characteristics of the reform efforts during these two distinct phases. Among the reforms of governance in Russia in this period, two central interrelated reforms, the reform of the civil service, and administrative reform are analyzed. The agenda of changes and their main directions have been studied for each of the reforms. It is argued that the main focus of the reforms is on the change of planning, the formation of integrated services, the digitalization of public service and services, the change in the regulatory climate, the "top-down" evaluation of the effectiveness of the apparatus, the development of flexible schemes of initiative budgeting. There is a change also in the orientation of education in the field of public administration. The transition from COVID -19 to the sanction period of the reforms is characterized primarily by changes in the motivation of the apparatus, an emphasis on the security of managerial decision-making and the protection of electronic communications, a predominant increase in wages for the military and law enforcement services, a smooth departure from the stages of the Bologna education system ( Master's and Bachelor's degrees).
CONTINUITY VERSUS CHANGE: EVOLVING TRAJECTORIES OF CHINESE PUBLIC ADMINISTRATION
Authors:   Fudan University, Jing Yijia , Zhang Zijuan ,   Fudan University
Published: October 2023

China’s public administration system has been shaped by incremental reforms since China started its reform and opening up in 1978. These reforms highlighted a delicate balance between continuity and change so gradual, incessant, and autonomous adaptation to China’s socioeconomic development as well as to its external environment could happen. Since China moved into the “deep-water zone” in the recent decade, does this reform strategy remain effective? This article examines the Chinese way of introducing public administration reforms, with a focus on the reforms in the past decade. Although incremental reform has in general been kept useful, changing internal and external conditions in China have made it more difficult to achieve innovations and systematic transformation through incremental reforms. An apparent approach to politicization has replaced the fragile politics-administration dichotomy and reshaped the way of value balancing in China’s administrative system.
PUBLIC ADMINISTRATION PERFORMANCE: NEW EUROPEANUNION MEMBER STATES
Authors:   Matej Bel University, Nemec Juraj
Published: October 2023

Measuring the performance of public administration systems represents a typical “wicked problem”, as it involves a number of complex implementation issues. However, even in the current period, when the ideology of New Public Management is dead for most experts, the European Union, international organizations and think tanks are trying to measure and compare the performance of public administration systems of countries. This paper summarizes the main initiatives of the European Union in this field and tries in its main part to review the situation of the new European Union member states from Central and Eastern Europe. Qualitative secondary analysis of data and simple statistics are the main methods of this paper, which is an original contribution to its general topic. The findings show that the main tools used by the European Union to measure and manage the performance of public administration in the member and candidate countries are the European Semester, the recent EUPACK project, the standards developed by SIGMA OECD for the candidate countries and various statistical surveys. The data obtained show that the performance of public administrations in the new EU Member States from the CEE region varies widely, with most of them being “followers”. The reasons for such large differences in performance should be the subject of further research.

Authors: Smolka Moritz
Published: October 2023

Long-read Structural Variation (SV) calling remains a challenging but highly accurate way to identify complex genomic alterations. Here, we present Sniffles2, which is faster and more accurate than state-of-the-art SV caller across different coverages, sequencing technologies, and SV types. Furthermore, Sniffles2 solves the problem of family- to population-level SV calling to produce fully genotyped VCF files by introducing a gVCF file concept. Across 11 probands, we accurately identified causative SVs around MECP2, including highly complex alleles with three overlapping SVs. Sniffles2 also enables the detection of mosaic SVs in bulk long-read data. As a result, we successfully identified multiple mosaic SVs across a multiple system atrophy patient brain. The identified SV showed a remarkable diversity within the cingulate cortex, impacting both genes involved in neuron function and repetitive elements. In summary, we demonstrate the utility and versatility of Sniffles2 to identify SVs from the mosaic to population levels.

Onymic space of Ukrainian comparative paramias (based on the material from the collection of Matviy Nomys “Ukrainian sayings, proverbs, and the like”)
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Bondarenko Maksym
Published: October 2023

Background. In today’s dynamic world, Ukrainians, like other peoples, are trying to preserve their national identity. Studying the peculiarities of the linguistic world of our ancestors becomes a primary task in modern linguistics, because language is a kind of mediator that ensures continuous communication between different generations. For many of us, it is important to feel the persistence of language and cultural traditions. The paremic subsystem of the Ukrainian language is the most interesting and the most eloquent. The study of paremias not only makes it possible to delve into the depths of the ages and trace the purely lexical or grammatical features of the language at a certain synchronous section, but also to try to reproduce important fragments of the linguistic picture of the world of our ancestors, which will help to understand their way of thinking. The purpose of this study is to find out the peculiarities of the organization of the onymic space of comparative paremias, attested in the collection of M. Nomys “Ukrainian proverbs, sayings, and the like” (1864), to determine the role of precedent onyms, which are important components of comparative proverbs and sayings, in the linguistic picture of the world of Ukrainians of the 19th century. Methods. The comparative and qualitative methods were applied. Results. During the study, the structure of the onymic space was characterized, its components – onymic fields (anthroponymic, toponymic, as well as ethnonymic) were distinguished and analyzed. It was found that the anthroponymic field is quite informative and bright, which most often includes units with such anthroponyms and their derivatives: Настя, Сидір, Хведько, Семен, etc. In addition, comparative paremias with precedent onyms (Гоне, як вітрів батько; Побілів, як Пилат) are considered and characterized. The onymic components of these units have a wide cultural and historical context, and are also powerful linguistic and ethnocultural codes of the Ukrainian people. The field of toponyms is valuable for the study of socio-historical realities. Proverbs and sayings often include the following toponyms and their derivatives: Очаків, Переяслав, Поділля, Полісся, etc. It is not surprising that the ethnonymic field is the largest. The collection of M. Nomys contains proverbs and sayings, which include the following ethnonyms: жид, циган, москаль, русин, швед, татарин, etc. The conducted study of the onymic space of Ukrainian comparative paremias made it possible to characterize the system of views and value orientations of our ancestors, to reconstruct the fragments of the linguistic and conceptual pictures of the world of Ukrainians of the 19th century, which are partly lost today.
Manipulative messages in the headlines of media sources
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Holota Taras
Published: October 2023

In this article, the author analyzes headlines on digital platforms of media sources, paying special attention to the manipulative content of the delivered messages. The research is based on the material of three websites, the authors of which manipulate the emotions of the recipients while providing information – “Tarasova Pravda“, “Naspravdi.Today”, and “Politeka”. The basic aspects of suggestive influence and manipulation of information during the speech act are defined and explained. In today’s rapidly evolving digital landscape, understanding the linguistic mechanisms of manipulation and suggestion in written texts is becoming increasingly crucial. This study not only sheds light on the deceptive methods employed in the headlines of Ukrainian-language online media resources but also highlights the importance of fostering media literacy among consumers. By enhancing awareness of manipulative tactics and promoting critical thinking skills, individuals will be better equipped to discern fact from fiction, ultimately contributing to a more well-informed society. The advancement and proliferation of cutting-edge information and communication technologies have led to an escalation in dissemination of manipulative texts. It can be posited that suggestion operates as a crucial instrument of verbal manipulation in written materials. Consequently, our investigation primarily focuses on examining manipulative texts (specifically, headlines within the context of this article) concerning their suggestive component. The research vectors for this issue encompass the linguistic analysis of manipulative texts for categorization purposes, recognition of suggestion components, exploration of linguistic methods employed for disinformation, and countermeasures against verbal manipulation. The objective of this article is to scrutinize the headlines of news articles featured on Ukrainian-language online media resources (based on materials from three websites: “Tarasova Pravda”, “Naspravdi.Today”, and “Politeka”), as well as to detect, classify, and interpret linguistic techniques of manipulation and suggestion used in messages, excluding the proportion of manipulative content. The conducted linguistic analysis based on the 100 headlines gives reason to claim that 66.67 % of the article headlines in the three news web portals we have investigated contain messages aimed at manipulating emotions – “Tarasova Pravda” (33.33 %), “Naspravdi.Today” (76.67 %), and “Politeka” (90 %).
Let’s not deny our own: linguistic essays on the history of word usage
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Hnatiuk Lidiia
Published: October 2023

The complex historical fate of the Ukrainian language has primarily affected its vocabulary, which has undergone significant changes over the past two centuries. In the new Ukrainian literary language, which emerged on a folk basis thanks to the works of Ivan Kotliarevskyi and Taras Shevchenko, many words inherited from the old Ukrainian literary language were replaced by synonyms from the vernacular speech. As a result, modern Ukrainian speakers may not perceive archaic lexemes as Ukrainian, even though these words of Proto-Slavic origin were already attested in Old Slavonic language and actively used in the Old Ukrainian period (14th–18th centuries), continued to be used in the new Ukrainian literary language until the first quarter of the 20th century, and are still in use in Ukrainian dialects. The article demonstrates the “Ukrainian-ness” of archaic lexemes such as время, год, нельзя, and послідній. Based on lexicographic works of the 19th to the first quarter of the 20th century, including the “Dictionary of the Ukrainian Language” by P. Biletskyi-Nosenko, the “Dictionary of the Ukrainian Language” edited by B. Hrinchenko, the “Ukrainian-German Dictionary” by Y. Zhelekhivskyi and S. Nedilskyi, the “Russian-Ukrainian Dictionary” by M. Umanets and A. Spilka, and the “Russian-Ukrainian Dictionary” edited by A. Krymskyi and S. Yefremov, as well as texts by Ukrainian writers of the 18th–19th centuries, including Hryhorii Skovoroda, Ivan Kotliarevskyi, and Hryhorii Kvitka-Osnovianenko, Romantic poets, Taras Shevchenko, and collections of paroemias compiled and organized by M. Nomys and I. Franko, the history of the usage of these words throughout the centuries is traced. Based on dialectal dictionaries, it is shown that these archaic lexemes continue to be used in various Ukrainian dialects, including Boyko, Bukovynian, Hutsul, Central Dnieper, East Slobozhanskyi, and others. This is a trace of the past literary-written tradition, evidence of our language-historical memory, and not elements of the Russian language or surzhyk. Misunderstanding the nature of such lexical units can distort Ukrainians’ perception of their national identity.

Published: October 2023

The range of applications for drives and gears stretches over numerous technological fields. The gearbox is found in every mechanical machine and represents only one small but important sub-application. Industry as a whole has a constant demand for new individual solutions tailored to solve particular problems. But again and again, it is called upon to find new ways of transmitting movements that a particular component is required to conduct so as to attain a particular result. Harmonic drive products are unique precision speed reducers playing important roles in robots, semiconductor manufacturing systems, factory automation equipment and furthermore, in aerospace equipment. The greatest benefits are the zero-backlash characteristics and the weight and space savings compared to other gears because our gear mechanism consists of only three basic parts. They are the: Wave Generator, Flexspline and Circular Spline.

This methodology has been designed to enable both the easiest possible implementation in practical conditions and the most effective use of the knowledge strategy in supporting the creation and implementation of business strategy.
RESEARCH AND DESIGN OF A PATH PLANNING USING AN IMPROVED RRT* ALGORITHM FOR AN AUTONOMOUS MOBILE ROBOT
Authors:   Mechatronics Department, School of Mechnical Engineering, Hanoi University of Science and Technology, DANG THAI-VIET
Published: October 2023

Path planning is innately viewed as a multi-objective optimization problem (MOOP) of the shortest path and the smallest distance to collision-free obstacles. The position of the mobile robot is definitively identified based on data derived from constructing maps with SLAM or extracting data from camera frames. Due to the complexity of the surroundings, obstacle avoidance still requires a complex sensor system with a high processing efficiency demand. The study provides an improved RRT* algorithm for mobile robot path planning in a given environment. RRT* will optimize the number of grid nodes based on the optimal cost functions of nodes in the searching environment. The improved RRT* algorithm with a safety cost increases the efficacy of obstacle avoidance. Hence, an improved RRT* algorithm based on the traditional RRT algorithm will remove redundant path nodes. Furthermore, the third-degree B-spline curve will smooth the path while ensuring MOOPs. Last but not least, simulations and experiments are shown to demonstrate the effectiveness of the suggested strategy.
AUTONOMOUS MOBILE ROBOT PATH PLANNING BASED ON ENHANCED A* ALGORITHM INTEGRATING WITH TIME ELASTIC BAND
Authors:   Mechatronics Department, School of Mechanical Engineering, Hanoi University of Science and Technology, DANG THAI-VIET
Published: October 2023

Path planning is the core technology to realize mobile robot navigation. The enhanced A* algorithm with a time elastic band method (TEB) is utilized to aim at the collision problem in a complex environment. A grid-based method transfers the complex environment to a simple grid-based map. The mobile robot's position is determined based on information from the given maps. Optimizing the search point strategy and removing redundant path points reduces the path length and computational scale. The approach yields a safe trajectory in the local path using a time elastic band. The collision cost function combined with the preview deviation angle tracking method ensures the minimum collision-free distance to obstacles and the shortest path. Furthermore, the third-degree B-spline curve will improve the performance of the mobile robot path at the steering angles. Simulated results illustrate the correctness of the proposed method.

Nowadays, the research and development activities performed in the area of internal combustion engines are focused on the LTC technologies, especially on the HCCI technology. It is so because these innovative technologies are characterized by high operational efficiency as well as by low emissions of nitrogen oxides (NOX) and particulate matter (PM). The combustion process LTC is able to utilize various fuels. The kind of fuel, together with its physical and chemical properties have a major influence on engine power output and gaseous emissions. The presented scientific contribution deals with analysis of an experimental engine operating with the HCCI combustion, specifically it deals with operational influences of several selected fuel mixtures. There is investigated an influence of the fuel mixtures, which consist of different components with various properties, on the engine power output and on the gaseous emissions. These experimentally applied fuels were created as the mixtures of isooctane and n-heptane using different mixing ratios. The obtained results offer a global view on a real effect of the fuel components applied in the fuel mixtures.

COMMUNITY EMPOWERMENT THROUGH THE DEVELOPMENT OF BATIK MOTIFS AND TRAINING BASED ON THE DECORATIVE VARIETIES OF THE SINGOSARI TEMPLE SITECandirenggo village has extraordinary tourism potential to be developed as a source of community empowerment. One of these potentials is the existence of Singosari Temple. Unfortunately, the existence of Singosari Temple cannot be utilized optimally because it only relies on tourist visits to the temple and surrounding sites. Even though the Singosari Temple site has so many ornamental motifs on some parts of the temple as well as on some artifactual relics located in the temple courtyard. This article aims to explain the development of batik motifs by taking inspiration from the variety of decorations that exist in Singosari Temple and several statues around it. Then, the motif was offered to the people of Candirenggo village through batik training activities. The method of developing batik motifs was through identification studies at the Singosari Temple site. Then continued with focus group discussion activities with archeologist and local community leaders. The result of this development is a form of batik motif named Singhāsana Padma. In the final stage, a community empowerment program is carried out through batik training activities in Singosari village which can be used for iconic merchandise for Singosari Temple tourism.Kelurahan Candirenggo memiliki potensi wisata yang luar biasa untuk bisa dikembangkan sebagai sumber-sumber pemberdayaan masyarakat. Salah satu potensi tersebut adalah keberadaan Candi Singosari. Namun sayangnya, keberadaan Candi Singosari belum bisa dimanfaatkan secara optimal karena hanya mengandalkan kunjungan wisatawan ke candi dan situs sekitarnya. Padahal situs Candi Singosari memiliki kekayaan motif ragam hias pada beberapa bagian dinding candi maupun pada beberapa peninggalan artefaktual yang terletak di halaman candi. Artikel ini bertujuan untuk memaparkan pengembangan motif batik dengan mengambil inspirasi dari ragam hias yang ada pada Candi Singosari dan beberapa arca di sekitarnya. Untuk kemudian, motif tersebut ditawarkan kepada masyarakat Kelurahan Candirenggo melalui kegiatan pelatihan membatik. Metode pengembangan motif batik ini melalui studi identifikasi di situs Candi Singosari, lalu dilanjutkan dengan kegiatan focus group discussion dengan para arkeolog dan tokoh masyarakat setempat. Hasil dari pengembangan ini adalah bentuk motif batik yang diberi nama Singhāsana Padma. Pada tahap akhir dilaksanakan pemberdayaan masyarakat melalui kegiatan pelatihan membatik di Kelurahan Singosari yang dapat dimanfaatkan untuk merchandise ikonik untuk wisata Candi Singosari.

Paraparesis hátterében igazolódott myelitis transversa differenciáldiagnosztikai kihívást jelentő esetét mutatjuk be egy 42 éves nőbetegnél. A részletes kivizsgálás eredményeként a syphilis egyértelműen igazolódott, a myelitis hátterében a liquor mikrobiológiai eredményei, a liquor rutinvizsgálata és a klinikai tünetek alapján a valószínűsíthető neurosyphilis diagnózis volt felállítható. Esetünkben a syphilis kezelési protokollja alapján alkalmazott antibiotikum-kezelésre adott jó terápiás válasz a neurosyphilis diagnózisát valószínűsíti. Jelen esetismertetés kapcsán áttekintjük a myelopathia/myelitis differenciáldiagnosztikai lehetőségeit. Napjainkban a syphilis világszintű terjedése miatt a témával kapcsolatos tudásunk bővítése szükséges.
Importancia relativa de los beneficios intangibles de la inversión extranjera directa en zonas francas: el caso de Costa Rica
Authors: Monge-González Ricardo , Rivera Luis
Published: October 2023

Este trabajo presenta una cuantificación de los beneficios de la inversión extranjera directa en Costa Rica establecida en las zonas francas, asociados a la participación de proveedores locales en las cadenas de suministro de las empresas multinacionales (MNC) y con la movilidad laboral hacia las MNC. Utiliza los cálculos realizados por Alfaro-Ureña et al. (2021) que se comisionaron al efecto. Se encuentra que las MNC generan beneficios tanto para los trabajadores que estas emplean (primas salariales) como para sus empresas proveedoras domésticas (derrames de productividad). Los resultados positivos sugieren la importancia de apoyar la mejora continua de proveedores actuales y potenciales de las MNC, con un enfoque de apoyo integral a los proveedores locales.
