The dolmen with surrounding stone platform of Gusan-dong, Gimhae, was a megalithic monument built to realize political purposes. This was the creation of a new landscape and the result of creating a kind of place with added social function and symbolic mean-ing. In making such a place, spatial implementation strategies that considered the physical environment of the time, the activities of local residents, and symbolic aspects were used. First, a strategy was used to form a central image by dramatically highlighting the characteristics of the construction space of the dolmen. The dolmen with surrounding stone platform in Gusan-dong was in a path that controlled movement throughout the Gimhae Basin, and occupied a node that could exert influence and play a role as a central point of the region. In addition, it had a spatial status that connected the physical and psychological boundaries divided by the Haebancheon River and wetlands, and integrated the location and foreign culture. Above all, the dolmen was a landmark representing visibility and sym-bolism, forming the central image of the local community and acting as a place with a spe-cial meaning. The second place-making strategy was the creation of space sequences and activity spaces that induced the repetitive experiences of the dolmen. The dolmen was built at the intersection of the axis of the Gimhae Basin, which formed a circular structure that induced a dynamic physical experience. In addition, the platform of the dolmen formed a segment through changes in the shape, height difference, and material of the structure and had the effect of inducing a strong visual experience. The visibility of the dolmen also induced con-tinuous visual experiences to local residents moving along the axis. On the other hand, it is highly likely that the platform was used as a space for repetitive ritual activities, and this seems to have influenced the formation of the placeness of the dolmen. The third strategy was the realization of a symbolic place that implies historicality. At that time, the Gimhae Basin was creating a politically meaningful place by adopting the dolmens with surrounding stone platforms as seen at 294 Daeseong-dong. It was the Gu-san-dong dolmen that expanded and reproduced these traditional tombs. This was a politi-cal act emphasizing the symbolism of the dolmen through the spatial expansion and visual-ization of the traditional order, and the symbolic landscape at the local level was converted to the regional level of the Gimhae Basin.

An insight on technical regulations for new activities in space

Space Traffic Management (STM) is becoming increasingly important as new space activities emerge, such as mega-constellations, on-orbit servicing etc. These developments, although promising great advances, nevertheless present complicated issues that demand stringent technical constraints. Effective STM necessitates extensive rules to ensure the safety, sustainability, and orderly execution of space operations. This research emphasizes the critical need for updated technical regulations that address the operational complexities involved with these new activities. It seeks to build a secure and collaborative space environment by establishing detailed legislative frameworks and emphasizing international cooperation, so ensuring the long-term profitability and success of space exploration and usage. Through meticulous analysis, the paper identifies regulatory gaps and proposes a robust framework capable of accommodating the evolving landscape of regulations. Drawing upon humanity's collective experience across different domains, the proposed framework aims to foster responsible growth in outer space while safeguarding its integrity for future generations. This paper examines the existing regulatory framework applicable to four distinct categories of New Technologies and Activities in space; identifies gaps where they exist; and suggests a capable and robust regulatory framework. This framework leverages humankind's experience in other domains to nurture and assist responsible growth in the outer space domain while ensuring proper stewardship of that domain, now and in the future. This paper is based on the report prepared by members of working group 4.2 of the Space Traffic Management Committee (TC 26).

The first section examines the current state of space activity issues and their gamification. The second section introduces the concept of the game utilizing the ARDI model, emphasizing the significance of each element in addressing these challenges. The third section focuses on the practical refinement of the proposed game concept. The article suggests that the game could serve as a tool for identifying and resolving ongoing challenges in space activity.

Развитие космической отрасли: опыт США, Китая и России

In recent decades, space has begun to be viewed as an important economic resource, an engine of global competition and technological development, capable of having a multiplier effect on the development of the entire economic system of a country. It is a necessary factor in global communication and information. Each state can use space for peaceful purposes, since it is a common resource for all countries. That is why the space industry is the object of the careful study by many researchers and a special sphere of government regulation. The top three leaders in the space industry are the USA, China and Russia. The purpose of this article is to conduct a comparative analysis of the development of the space industry in the USA, China and Russia, as well as to develop recommendations for improving the regulation of the Russian space industry based on foreign experience. The author selected the following characteristics as the main parameters of comparison: 1. Significant space achievements, 2. Industry financing, 3. Structure of the space industry, 4. The scale of private space sector development, 5. Motives for international cooperation in the field of space exploration. Based on the analysis, the features of space industry development in each country were identifi ed. Special attention in the study is paid to the Russian space industry. In particular, it was found that the main structural feature of the Russian space industry, in contrast to the USA and China, is the significant predominance of state-owned companies over private enterprises. This is associated with the lack of the necessary regulatory framework in our country and, as a consequence, the underdevelopment of the market for space products and services. At the same time, Russia can be considered a leader in terms of funding for the space industry (as a percentage of GDP), but in absolute financial indicators (in millions of dollars) Russia lags significantly behind the United States and China. In addition, Russia adheres to the practice of participating in international cooperation in the space sector, based primarily on political factors rather than economic motives, which fundamentally distinguishes its approach from the approach used by the United States. The article proposes a number of practical recommendations, the implementation of which, according to the author’s opinion, will contribute to increasing the efficiency of space activities in Russia.

Media Communications as a Context for Imprinting Formation

The author of this article posits that media communications serve as a context for the formation of imprinting — a psychophysiological mechanism whereby impressions or images are etched into the brain, evolving into stable behavioral programs. The identification of these programs is facilitated through the analysis of media texts with a high attention coefficient. The study analyzed 200 media texts across various typological niches within the contemporary media system: online news outlets, social media platforms (VK, Odnoklassniki), and blogs, including the “Zen” platform. The findings indicate that different typological segments of the media system represent distinct behavioral programs. In online news outlets, behavioral programs are explicitly manifested in cognitive actions aimed at understanding processes related to Russia’s economic and political landscape. In social media, the prevailing behavioral program is encapsulated in a sentiment inspired by the phenomenology of serendipity. The “Zen” blog platform reveals imprinting through the categories of “irresponsibility,” “playfulness,” and “hooliganism.” In other blogs featuring high attention indices, imprinting is observed in the contemplation of professional issues related to activities in the digital space. The various typological niches of the media system are geared towards the formation of heterogeneous psychophysiological mechanisms, which transform into an axiological foundation that shapes diverse behavioral programs.

The implementation of state's rights and obligations in outer space: is it equal?

The provisions of Outer Space Law govern a state's activities in outer space. The implementation of such activities needs advanced technology, which limits the ability of many countries to explore and exploit outer space. Data indicates that developed nations dominate outer space management, leaving countries without access to sophisticated technology unable to participate fully in space exploration and exploitation. This dominance triggers disparity between developed and developing countries, leading to unequal application of rights and obligations as outlined in Outer Space Law. While the law promotes international collaboration to address this issue, it does not explicitly require developed countries to involve developing nations in outer space activities. This study aims to refine the concept of international collaboration to ensure fair management and exploitation of outer space by all countries. This study is normative in nature, focusing on evolving the concept of international collaboration in outer space. Primary and secondary legal materials and non-legal sources were used as secondary data collected through a literature review and analysed qualitatively. The developed concept emphasises international cooperation and mutual assistance, proposing a framework for collaboration between developed and developing countries. This concept seeks to ensure equitable management of outer space. It reshapes the rights and obligations of states by encouraging all launching states to involve developing countries in space exploration and exploitation.

Outer space (cosmic) private law

The article presents the relevant results of an analysis of the process of regulating private space activities. At the same time, the separate focus is on the development of space law and the main problems that currently exist in space law, including those related to the confrontation between public space law and private space law, for example: regulation of space traffic; determination of ownership of objects obtained as a result of space activities; mining and other aspects of commercialization of space activities. Additionally, a list of the main legal tasks in private space activities that require an early solution is identified, and the steps that have already been taken in this direction are described, namely, new variants of terminology, interpretation, and classification of objects and subjects of space activities, space law, and space legal relations as well as a new theory for determining the legal status of outer space are proposed. In the final analysis, it was concluded that it is necessary to continue research in further formation and improvement of the elements, interpretations, and structure of Space Private Law. To this end, the author proposed an option for further scientific research on the formation of the structure of Space Private Law based on the establishment and definition of the basic principles, concepts, and elements of such law. At the same time, the author identified the main goals, objectives, object, and subject of such research, and also, preliminary, determined the research methodology that is vital to obtain the most effective scientific results. According to the author, the results of the study on the formation of the structure of Space Private Law will be base for future foundations for regulating private space activities and preventing many legal conflicts.

Blockade of the CCR3 receptor reduces neutrophil recruitment to the lung during acute inflammation.

Neutrophils represent one of the host's first lines of defense against invading pathogens. However, an aberrant activation can cause damage to the host. In the case of respiratory infections with viral or bacterial pathogens, one of the most common complications is the development of acute respiratory distress syndrome, in which neutrophil infiltration into the lung is a hallmark. Neutrophils gain expression of chemokine receptors under inflammatory conditions, and their activation can amplify the neutrophil responses. Earlier studies showed that neutrophils recruited to the lung mucosa during bacterial infection upregulate expression of CCR3 and ex vivo stimulation of CCR3 results in an increased neutrophil activation. Therefore, the modulation of effector functions or migration of neutrophils to target sites through chemokine receptors constitutes an opportunity for pharmacological intervention. We aimed to determine whether the blockade of the CCR3 using the specific antagonist SB-328437 reduces neutrophil recruitment and inflammation in the lung in the lipopolysaccharide (LPS)-induced lung injury model and influenza infection in mice. We found that neutrophils acquire CCR3 expression in the lung alveolar space. The intraperitoneal administration of SB-328437 reduced neutrophil recruitment to the lung alveolar space and reduced tissue damage in both the LPS-induced lung injury model and influenza infection. Moreover, treatment with SB-328437 reduced the percentage of neutrophils producing TNFα and neutrophil activation in the alveolar space. Together, these data suggest that CCR3 blockade might be a pharmacological strategy to prevent the aberrant neutrophil activation that results detrimental for the host but preserves sufficient effector response to control the pathogen.

Conditional Localization Pharmacology Manipulates the Cell Cycle with Spatiotemporal Precision.

Traditional pharmacology has limited control of drug activity and localization in space and time. Herein, we described an approach for kinase regulation using conditional localization pharmacology (CLP), where an inactive caged inhibitor is localized to a site of interest in a dormant state using intracellular protein tethering. The activity of the inhibitor can be regulated with spatial and temporal precision in a live cellular environment using light. As a proof of concept, a photocaged MPS1 kinase inhibitor (reversine) bearing a Halo-tag ligand tether was designed to manipulate the cell cycle. We demonstrate that this new caged reversine halo probe (CRH) strategy is capable of efficient localization and exceptional spatiotemporal control over spindle assembly checkpoint (SAC) silencing and mitotic exit.

Space Security and the Law of International Space Cooperation: The Need for Leadership and Coordination

In recent times space exploration and technological advancements hold prominent importance, the merger of space security and international collaboration must be paid attention too. Whereby, during the recent advancements in space technologies which include the proliferation of satellite and emergence of various space programs, the non-commercial and sustainable utilization of space must be taken care of. This paper explores and access the methodologies adopted and put into motion by nation having a well-established space program to address the difficulties faced while maintaining the space security along with ongoing space explorations. This research study will also pay emphasis towards analysing the already existing legal framework which directly governs various outer space activities, international organizations, role of governments and private industry players towards shaping of governance in outer space. In order to build trust and furthering the shared objectives in outer space and resolution of disputes among nation states, emphasis on how significant and valued international cooperation and diplomacy can prove to be. The various risks factors such as deliberate actions which are testing of anti-satellite weapons and dispersion of space debris in high volumes that the assets in space encounter are explored in this research. This study also discusses about case studies that have impacted the outer space and space explorations and other space missions positively as well as negatively in past instances. This study concludes the necessity of proactive leadership and teamwork in addressing the issue of space security and the legislation of international space cooperation. Roles of significant stakeholders, implementation of future course of actions with necessary changes to guide and provide policymakers in understanding the complexity of space reforms for peaceful utilization of outer space for both current and future human race.

Context and perspectives of sub-orbital activities and transit through airspace/ground support activities

This paper provides some considerations on the current context and perspectives concerning the sub-orbital activities and transit through airspace/ground support activities issued in the frame of the IAF-IAA-IISL Working Group on Space Traffic Management (STM). The group brought together experts from different backgrounds and countries in order to analyze the different aspects of these activities, namely, technically, programmatically, and legally.The rise in space activities, both orbital and suborbital, increases the number of possible interactions with national airspace, inducing potential problems of traffic management. Spacecraft transiting through airspace (both international and national) involve different objects (satellites, launch vehicles, rocket bodies, suborbital vehicles, aircraft …) and missions with varied associated risks. These risks can be generally characterized by the time in airspace, the velocity of spacecraft, and its altitude. Despite the increase in space activities, there are currently no binding international rules specific for spacecraft traversing through airspace. However, there are guidelines, national frameworks, recommendations from organizations (e.g. UN-COPUOS, OSI) covering part of the interaction of space activities and transit through airspace. Additionally, some may argue customary international law exists in the current practice of preventing fallout during launch/re-entry activity into sovereign airspace.The rising number of spaceports, both for orbital and suborbital missions, contribute to increase of space traffic in terms of location of the launch sites and of widespread type of launch and re-entry missions.The working group focused on the identification of the objects to be considered for this interaction, the current available rules and guidelines, the recommendations issued by specific organizations on the subject, and the experts’ advice in order to have a global view of the context and summarize some general recommendations for future operations.

Wasting and wanting: An extractive supply chain approach to outer space geographies

This article conceptualizes outer space geographies through the Earthly geographies of extractive supply chains, focusing on mines and discarded electronics (e-waste), in order to examine the material relations through which contemporary human engagements with outer space are being produced. It considers the emergence of billionaires-turned-astronauts within the waste-making practices of supply chain capitalism, critiquing this as a particularly stark example of the politics of sacrifice that need to be centered in debates concerning the present and future of human engagements with outer space. Drawing together literatures on waste, discard, supply chains, and frontiers, and informed by fieldwork in several mining and launch sites on four continents, the article argues that waste-making on Earth is constitutive of a set of contemporary space activities and shapes the manner in which the immensity of the cosmos is understood and engaged by diverse publics. It concludes by reflexively examining the potential epistemic violence of waste-making as a spatial analytic to link Earthly and outer space geographies.

Recognition of precession angles of non-cooperative targets based on deep learning with privileged information

With an increasing number of countries engaging in space activities worldwide, space non-cooperative target tracking and identification technology has become a prerequisite for safely conducting space operations. In order to the identify distant non-cooperative targets performing complex motions, this paper proposes a method to recognize difficult parameters by using easily available signal labels as privileged information, which is named Pi-FcResNet. The privileged information is connected to the output end of the network through a fully connected network and coupled with the linear layer of the main network. Through testing, our network achieved a recognition accuracy of 94.45 % for precession angles under high signal-to-noise ratio conditions. After incorporating the Convolutional Block Attention Module (CBAM), our method demonstrates fast fitting speed and robust performance. Testing on experimental data shows that, compared to traditional methods, our approach offers better stability and reproducibility in recognizing micro-motion parameters. This approach of using known information as additional information for deep learning networks holds great potential in the field of feature extraction for space non-cooperative targets undergoing complex motions.

Options for a Liability Framework for Commercial Low-Earth Orbit Destinations

Commercial Low-Earth Orbit destinations (CLDs) are the next milestone in the development of commercial space transportation, but the legal responsibilities of spaceflight providers, personnel, and spaceflight participants (SFPs) on board are not easily discernible. This article describes the purpose and goals of CLDs; assesses current regulations enforced against private companies’ activities in space; and proposes different liability frameworks for application to CLD activity. Development of a comprehensive liability regime is crucial to promoting innovation in commercial space, while also protecting the safety interests of all personnel and participants on board.

Cytome analysis (micronuclei and nuclear anomalies) in bioindication of environmental pollution in animals with nuclear erythrocytes

Assessment of cytogenetic homeostasis of indicator animals is of great importance in ecological monitoring. The simplest method of its study is micronucleus analysis. Animals with nuclear erythrocytes are often used as indicator animals. In addition to the micronuclei usually recorded, a wide range of cytological nuclear and cellular abnormalities (cytomic analysis) is encountered when assessing the spontaneous level and under the influence of anthropogenic factors. Spontaneous frequency of cytogenetic disorders in 36 species of fish, amphibians, reptiles and birds was studied. Ecological monitoring of territories of Kazakhstan with different types of pollution (radiation, petrochemical, pesticide, heavy metals, due to rocket and space activities) was carried out with the help of separate species of animals. The results of the study include comparative descriptions, schematics and microphotographs clearly demonstrating a wide range of cytological anomalies of nuclear erythrocytes of animals of different classes. The greatest spectrum of nuclear anomalies in the studied animals was registered at petrochemical and pesticide contamination of territories. Depending on the tasks and climatic-geographical conditions, all investigated species can be used as bioindicators. Testudo horsfieldii is an exception for desert regions due to high spontaneous micronuclei level in this species. A review of the names of the main nuclear anomalies is carried out and variants of its ordering are proposed.

Politeconometrics: The regulatory confluence theory as a mathematical framework for measuring the impact of regulations relative to other factors and externalities in the space industry

This paper introduces “Politeconometrics: The Regulatory Confluence Theory,” a novel mathematical framework designed to measure the impact of regulations in the burgeoning space industry. Traditional approaches to regulatory evaluation are inadequate in capturing the complexities of modern space activities. This paper addresses these limitations by proposing Politeconometrics, which combines econometrics, mathematical modeling, and regulatory theory to provide a comprehensive assessment of space regulations.The framework evaluates the efficacy of space regulations in advancing objectives across various jurisdictions, translating legal structures into quantifiable impacts, and identifying regulatory gaps. By incorporating factors like market entry feasibility, regulatory resistance, and industry dynamics, Politeconometrics offers a refined understanding of regulatory outcomes.Through case studies, including New Zealand’s space industry and the challenges of International Telecommunication Union (ITU) Spectrum Allocation, the paper demonstrates the practical application of Politeconometrics. The methodology involves data collection, assumption management, application of structural formulae, sensitivity analysis, and scenario simulations to ensure robust and actionable insights. The paper also explores the Regulatory Confluence Theory, which assesses the interconnectedness of regulatory frameworks and their cumulative effects on industry dynamics. This theory, combined with Politeconometrics, addresses the limitations of international space law by offering a dynamic, evidence-based approach to regulatory governance.Despite challenges like data availability and interdisciplinary integration, Politeconometrics and the Regulatory Confluence Theory provide significant advantages over existing methods. They offer a nuanced evaluation of the space industry’s regulatory environment, fostering innovation and sustainable development in space activities.

Jet Fuel as a Source of Soil Pollution: A Review

Kerosene is widely used in various types of anthropogenic activities. Its environmental safety is mainly discussed in the context of aerospace activities. At all stages of its life cycle, aerospace activity impacts the environment. In aviation, the pollution of atmospheric air and terrestrial ecosystems is caused, first of all, by jet fuel and the products of its incomplete combustion and is technologically specified for a number of models in the case of fuel leak during an emergency landing. In the rocket and space activities, jet fuel enters terrestrial ecosystems as a result of fuel spills from engines and fuel tanks at the crash sites of the first stages of launch vehicles. The jet fuel from the second and third stages of launch vehicles does not enter terrestrial ecosystems. The fuel components have been studied in sufficient detail. However, the papers with representative data sets and their statistical processing not only for the kerosene content, but also for the total petroleum hydrocarbons in the soils affected by aerospace activity are almost absent. Nevertheless, the available data and results of mathematical modeling allow us to assert that an acceptable level of hydrocarbons, not exceeding the assimilation potential, enters terrestrial ecosystems during a regular aerospace activity. Thus, the incoming amount of jet fuel disappears rapidly enough without causing any irreversible damage.

Space Traffic Management: Data Fusion

First, the terminology and organizations (data contributors and aggregators) associated with data fusion is discussed. Next, the various “levels” of data fusion are delineated, and a detailed breakdown of the data levels associated with STC and STM (and indeed all space operations) is provided. The taxonomy of data required for safe collaborative space activities are detailed. And finally, data fusion is explored in the context of STC and STM, including the levels, techniques, data sources, and state representations used. And finally, the benefits and limitations of the various data fusion types and levels are outlined with practical examples provided.

The Prosecutor’s Office of the Baikonur complex and its Place in the Russian Prosecutor’s Office System

Currently, the role of the prosecutor’s office in the system of public authorities in Russia is quite high. This is confirmed by a wide range of functions assigned to the prosecutor’s office by Federal Law No. 2202-1 dated 17.01.1992 “On the Prosecutor’s Office of the Russian Federation”, organizational and administrative documents of the supervisory authority, as well as the practical participation of the prosecutor’s office and coverage of its activities in the information space. Of course, specialized prosecutor’s offices deserve special attention, a number of which are not textually fixed in the above-mentioned law. These include, for example, the prosecutor’s office of the Baikonur complex, which has specifics due to various features, which will be discussed. Based on the analysis of the activities of the prosecutor’s office of the Baikonur complex, as well as the doctrinal provisions in relation to it, the author’s conclusions and proposals concerning the further development of the prosecutor’s office under consideration are formed. One of the key proposals is the development and publication of an Order of the Prosecutor General of Russia, consolidating the provisions concerning the activities of the Prosecutor’s office of the Baikonur complex.

International Legal Regulation and Management of Space Waste on Celestial Bodies

The present article explores the international legal regulation of space waste on celestial bodies and the ecological challenges that space missions will pose in the near future. The lack of a shared vision of whether space waste production should be minimized on celestial bodies is causing uncertainty in the planning of future space missions. Leading private space companies are proposing the transfer of dangerous space waste produced from Earth into outer space. The excessive generation of space waste would increase the risks of activities such as space tourism, and space research and will threaten scientific fields such as radio astronomy. The political alliances that exclude a priori third parties will increase the risk of a generation of unnecessary orbital space debris and space waste on celestial bodies because of the development of several space missions in the same field. The sustainability of space missions on celestial bodies and the protection of the outer space environment should become a guiding principle for both national and international legal regulation of space activities. This article argues for the urgent need to establish comprehensive international regulations and monitoring mechanisms to manage space waste on celestial bodies, emphasizing sustainability and cooperation among space-faring nations.
