Elucidation of the mechanisms of the development of liver steatosis, which are at the heart of the pathogenesis of nonalcoholic fatty liver disease (NAFLD), will allow the introduction of new effective treatment methods into medical practice, as well as the development of new measures for the correction of this disease and accompanying pathologies. The purpose of the research is to establish the enzymatic activity of the complexes of the electron transport chain of the mitochondrial membrane of rat hepatocytes and to evaluate the corrective effect of the multiprobiotic “Symbiter acidophilic” concentrated or nanocrystalline cerium dioxide on the formation of steatohepatosis induced by neonatal sodium glutamate administration. The experiments were carried out on 50 white non-linear male rats; the direction included the study of the mechanisms of the development of steatohepatosis in 4-month-old rats, which were administered monosodium glutamate in the neonatal period, and the study of the functional state of the liver in rats after the neonatal administration of monosodium glutamate against the background of periodic administration of a multiprobiotic or nanocrystalline dioxide cerium. It was established that neonatal administration of monosodium glutamate causes metabolic changes in 4-month-old rats, manifested in the disproportionate accumulation of fat with the development of visceral obesity without hyperphagia, dyslipidemia, and steatohepatosis. In 4-month-old rats, after neonatal administration of sodium glutamate, the development of steatohepatosis was accompanied by mitochondrial dysfunction, which was manifested by changes in the lipid composition of the inner membrane of hepatocyte mitochondria with an increase in oxidized products and a change in the enzymatic activity of all complexes of the respiratory chain. In rats injected with monosodium glutamate in the neonatal period, periodic use of the multiprobiotic “Symbiter acidophilic” concentrated or nanocrystalline cerium dioxide significantly restored the functional state of the liver, reduced the manifestations of oxidative stress and prevented the development of steatohepatosis, which indicates the antioxidant effect of these drugs and the possibility of their use for prevention of steatohepatosis.

Alzheimer’s disease is a chronic neurological illness that causes considerable cognitive impairment. However, there is no effective treatment for this disease. Therefore, the current study aimed at investigating the long-term effects of fluoxetine and memantine on biochemical markers of Alzheimer’s disease in scopolamine-induced mice. In this study, adult female mice were divided into four equal groups; normal control received distilled water only, the untreated Alzheimer’s disease group received scopolamine intraperitoneal IP/SCM for 14 days, following which distilled water was given for six months, the memantine-treated Alzheimer’s disease group received IP/SCM for 14 days then memantine hydrochloride for 6 months, the fluoxetine-treated Alzheimer’s disease group received IP/SCM for 14 days then fluoxetine hydrochloride for 6 months. The results show that after 2 weeks of induction the mean level of amyloid β and MDA were significantly elevated, while the mean level of BDNF and TAS were significantly reduced in comparison with the normal control group. After 3 months, both treatments (memantine and fluoxetine) caused a highly significant decrease in the mean levels of amyloid β and malondialdehyde as well as an increase in the mean levels of brain derived neurotrophic factor and total antioxidant status in Alzheimer’s disease treated mice in comparison with Alzheimer’s disease untreated mice. However, after 6 months of treatment, the effects of fluoxetine were more significant than those of memantine. In conclusion, fluoxetine has significant effects on biochemical markers of Alzheimer’s disease and these effects are time-dependent as well as more significant than those of memantine, which suggests the potential usefulness of the former in treatment of this disease.

Published: August 2024

Due to the large number of nuclear power plants around the globe and the growing threat of radioactive accidents, a complex assessment of the biological consequences of the Chornobyl disaster is a relevant issue. Study of mutagenic activity of prolonged and chronic action of radionuclide pollution of soil in the Chornobyl Exclusion Zone long after the accident will allow us to identify the current level of threat they pose to the human genome and can reveal specific cytogenic markers of radionuclide environmental pollution. For this purpose, we germinated seeds of wheat of soft winter varieties Smuhlianka and Bohdana in soil samples from the Chornobyl Exclusion Zone 35 years after the disaster. Specific activity of Cs-137 and Sr-90 accounted for 4.5–28.2 kBq/kg. To determine the frequency and range of chromosomal aberrations, we used the anaphase-telophase method. In aberrant cells, we studied extracellular distribution of chromosomal disorders. The frequency of aberrant cells was 3.53–7.55 times above the spontaneous level. High mutagenic activity remained in the conditions of the lowest density of radionuclide pollution of soil. The range of chromosomal disorders mostly included paired fragments and bridges and containd chromosomal acentric rings, binding of chromosomes, myocardium, and lagging and leading chromosomes. Radionuclide pollution in the Chornobyl Exclusion Zone induced multiple cellular aberrations in the rhizome meristem, the share of which was the highest in case of low specific radionuclide pollution of soil, and exhibited a tendency towards decrease against the background of the highest density of radionuclides. Pollution of the environment with radionuclides as a result of disasters at nuclear energy objects poses a threat to the human genome and is a global problem, requiring state support to solve through systematic genetic monitoring in readionuclide-polluted territories and areas adjacent to them.

In recent years, drought has become one of the most widespread global problems as a result of drastic climate change all over the world. In order to increase the efficiency of cultivation of agricultural crops under the conditions of drought, research was conducted aimed at determining the diversity of endophytic microorganisms of xerophytic and halophytic plants grown under the influence of this stress factor and evaluating their characteristics and potential is of great importance. This article describes the results of the research aimed at isolating, identifying and evaluating some properties of endophytic bacteria from Peganum harmala L., which is widespread in arid regions of Uzbekistan. These data are being published for the first time in terms of area and vegetation. The results of studying P. harmala endophytic bacteria diversity, species composition, resistance to pathogenic fungi confirm that this plant is a potential source of promising endophytic bacteria. In the experiments, 24 promising isotypes of endophytic bacteria were isolated from P. harmala, which were the research objects. Five strains were selected by evaluating the colonization potential of the isolated isolates under drought conditions and resistance of the selected strains to pathogenic fungi was evaluated. These promising strains were identified using molecular genetic methods.

The quality of goat milk can be affected by mesophilic aerobic and facultatively anaerobic microorganisms (MAFAnM), intestinal bacteria, psychrotrophic, some pathogenic microorganisms, fungi, etc. Traditional microbiological methods, which are used to determine the safety of milk, do not provide an opportunity to obtain an instant result, require the preparation of nutrient media and glassware, which takes up work time and is energy-consuming. We have carried out studies of goat milk by classical (using conventional and selective nutrient media) and alternative modern (using test plates, which are widely used to control microbiological contamination in the food industry) methods. As a result of the conducted research, it was established that the bacterial contamination of goat milk was within the permissible limits. There were no significant differences in the results of using the test plates. According to the classical method, the average indicators of the number of mesophilic aerobic and facultatively anaerobic microorganisms were 4.97 ± 0.14 lg CFU/mL, according to the alternative method – 4.86 ± 0.13 lg CFU/mL. Escherichia coli was isolated in four samples (with an average concentration of microorganisms of 1.86 ± 0.62 lg CFU/mL), in the same samples Enterobacter spp. in the amount of 1.77 ± 0.61 lg CFU/mL. In three samples, the presence of Proteus spp. with average concentration values of 2.19 ± 0.15 lg CFU/mL. Using an alternative method, contamination of milk with Escherichia coli (1.53 ± 0.33 lg CFU/mL) was detected in five samples, coliform bacteria were isolated in four samples (1.49 ± 0.50 lg CFU/mL). Staphylococcus aureus was not detected by any of the methods, but other representatives of the genus Staphylococcus were detected in all samples by both classical and alternative methods (2.48 ± 0.05 and 3.01 ± 0.07 lg CFU/mL). Using the classic method, it was established that two samples were positive for Enterococcus spp. (2.46 ± 0.08 lg CFU/mL), Bacillus spp. were isolated in six samples (1.70 ± 0.09 lg CFU/mL), in three – Clostridium spp. (1.66 ± 0.06 lg CFU/mL), in all six samples psychrotrophic bacteria (2.09 ± 0.26 lg CFU/mL) and yeast (2.41 ± 0.24 lg CFU/mL), four of the samples contained single colonies of mold fungi of the genus Aspergillus. Pathogens Listeria monocytogenes and Salmonella spp. not found. It will be promising to study the dependence of the milk microbiome on environmental factors, as well as the influence of the milk microbiota on the course of technological processes, quality and safety indicators during the production of goat cheese or other dairy products.

The productivity of bee colonies mostly depends on the influence of exogenous factors. The most significant ones include: the presence of a honey base, climatic conditions, environmental temperature, etc. The stability of microclimate indicators in the nest significantly affect the growth of families and nest. The vital temperature range in the post-embryonic period ranges from 30–38 °С. For normal brood development, the incubation temperature should be 34–35 °С. The intensity of growth during this period is largely determined by the influence of climatic conditions, including temperature. As a result of decrease in temperature, there is a densification of the placement of bees, which are more concentrated in the central, breeding part of the nest. Under these conditions, hypothermia of individual areas of the brood, located on the peripheral parts of the honeycombs, beyond the healthy temperature range, is sometimes noted. This is manifested by a sharp drop in the ambient temperature, when there is a numerous brood in the family, or if the nest is not expanded properly. In order to study the influence of cold stress on the development of offspring, two groups were formed. The group incubated at a temperature of 35 ºС was considered the control group. The experimental group was a group which was grown at a temperature of 32 ºС. After the brood was sealed, pupae were selected every 2 days. At the same time, their mass, the content of total lipids and the ratio of their individual classes were determined. It was found that under the influence of cold stress during brood development, the duration of the incubation period increases by 35–42 hours. It has been established that the adaptation of bees to cold includes a complex of physiological and biochemical processes, among which changes in the mass and composition of lipids play a significant role. The dynamics of triacylglycerides under optimal and stressful conditions of incubation were studied. Taking into account their functional purpose as the main element of energy supply of metabolic pathways, such dynamics indicate profound changes in the processes of energy exchange. When studying the mechanisms of adaptation to cold, a change in the ratio of phospholipid classes, the expression of which is induced by the effect of cold, was revealed. The results of this study bring a deeper understanding of the adaptation mechanisms of honeybees' response to changes in brood incubation temperature. They expand data on the biology of bees during critical periods of growth and development.

Salinization and drought are the most important abiotic stress factors causing significant impact to the agriculture of Uzbekistan. To eliminate the negative consequences of the drying of the Aral Sea, large-scale works are currently being conducted on this territory to create protective forest plantations of halophytic trees and shrubs. An important issue in the protection of forest plantations is the isolation, identification and monitoring of phytopathogenic fungi associated with these forest plantations. The study's objective was to isolate Alternaria fungi from Haloxylon aphyllum (Minkw.) Iljin, Tamarix hispida Willd., T. ramossisima Ledeb. and to also apply a diagnostic marker using PCR assays to detect and identify Alternaria pathogens in these plants. As a result of the study, 10 strains of Alternaria fungi were isolated from plant samples of black saxaul – Haloxylon aphyllum, and two tamarisk species – Tamarix hispida, Tamarix ramossisima. The dominant species was: Alternaria tenuissima (Kunze) Wiltshire. β-tubulin gene was used as a molecular marker to distinguish and identify Alternaria spp in 34 leaf samples of Haloxylon aphyllum, Tamarix hispida and Tamarix ramossisima. The primer set used in the PCR assay was shown to be capable of detecting the presence of Alternaria in the leaves. Therefore, a β-tubulin-based diagnostic marker can be widely applied for monitoring of Alternaria infecting a wide-range of halophytic trees and shrubs in the protective forest plantations.

The rise of e-commerce necessitates sustainable practices for a greener future. While the e-commerce boom offers immense economic opportunities, minimizing its environmental impact and upholding ethical business conduct are essential. Current research on e-commerce heavily focuses on information technology (IT) for understanding and improving consumer acceptance. However, a critical gap exists in exploring IT's potential contributions to sustainability, crime prevention, and environmental safety. This study bridges this gap by exploring the role of IT integration in managerial practices to enhance environmental protection, crime prevention, and foster sustainability within Bangladesh's booming e-commerce sector. Focusing on e-commerce managers' perspectives, the research examines effective leadership strategies for IT implementation. Additionally, it utilizes the Technology Acceptance Model (TAM) to analyze the relationships between user perception and its impact on e-commerce performance. Using a structured questionnaire, we collected the data from 418 e-commerce managers. The research design incorporates a robust framework, hypothesis formulation, and methodological rigor grounded in TAM principles. The findings reveal a significant positive contribution of IT to environmental protection, crime prevention, and overall sustainability within the e-commerce sector. Managers' perceptions highlight that effective IT utilization ensures environmental safety, safeguards data against criminal activity, and promotes organizational sustainability. Furthermore, this research provides a roadmap for e-commerce businesses to accelerate their sustainability efforts. It also equips academics with valuable insights to advance knowledge on building a secure and sustainable future in the digital age.

This study evaluates the influence of logistics communications on the investment activity of enterprises in the context of capital movement. The issue of developing an effective toolkit for performing such an assessment was resolved.
The grouping of types of logistic communications used for the movement of capital was carried out according to a number of characteristics. A model for evaluating logistic communications, which are used for the movement of capital, has been developed. Modeling of the process of determining the investment potential of companies was carried out. A method for assessing the influence of logistic communications on the investment activity of enterprises is proposed.
An evaluation of logistic communications, which are used for the movement of capital, was carried out for a sample of enterprises. It was established that the average values of the integral level of the properties of the information transmitted by these communications are: for completeness – 0.302; for accuracy – 0.313; for relevance – 0.348; in this case, for all the listed properties – 0.032. At the same time, with an increase in the specified level, the realization of the investment potential of enterprises increases and their investment activity increases.
The peculiarity of the developed toolkit is that its application makes it possible to obtain accurate and comprehensive results of evaluating the impact of logistics communications on the investment activity of enterprises in the context of capital movement. The proposed toolkit could be used by enterprises of all types of economic activity when assessing their existing investment potential and when designing logistic communications, which are used to transmit the information necessary to realize the specified potential. This could help increase the economic efficiency of companies' investment activities

The object of this study is the business processes of making an investment decision based on determining the state of the investment attractiveness of the enterprise.
To support the adoption of investment decisions under the conditions of a fast-moving and dynamic environment, information-analytical support to the algorithm using intelligent information systems has been developed. The relevance of the study is justified by the continuous development of digitization processes, in particular in the financial realm. The traditional approach to the reproduction of management decision-making technology is complemented by the tools and methods of intelligent information systems. In particular, the modeling of the target subject area using UML made it possible to determine the main requirements for the projected information-analytical support (user roles, available options, types of connections and the logic of interaction between them). SQL queries to the information database speed up the process of processing and obtaining the necessary data samples. Business intelligence (BI) tools are used to create interactive reports that provide access to operational financial data. At the stage of making investment decisions, these tools make it possible to  study a wide range of analytical data based on the results of the assessment of the investment attractiveness of the enterprise obtained at the previous stage of the developed algorithm. Monitoring of the main indicators of the enterprise's investment attractiveness is carried out on the basis of a dashboard, an information panel (display) with graphs, tables, and figures that clearly reflect the dynamics and rates of change of the investigated indicators. The results of the use of algorithmic information-analytical support make it possible to quickly prepare and make investment decisions. A visual description of the projected information-analytical support, visual content of the results of investment analysis, the validity of decisions due to the use of reliable retrospective information from an aggregated database

Published: August 2024

The object of this study is the existing regulatory approaches to the definition of private law forms of technology transfer in the law of the European Union, international treaties, and agreements.
In the course of research and generalization of existing concepts, it was established that they are not unified and differ significantly. It has been proven that this does not meet the needs of technology transfer participants and destabilizes the technology transfer process. The expediency of improving the existing concept of defining private law forms of technology transfer by unifying them has been substantiated. Recommendations on the list of the main forms of technology transfer have been formed based on a systematic analysis of regulatory legal acts that determine the content of technology. A classification of the main private law forms of technology transfer has been proposed. Three main groups of private law forms of technology transfer were distinguished. The expediency of assigning each private law form of transfer to a certain group was substantiated. Directions for improving the current regulation of private law forms of technology transfer have been formed, by summarizing and supplementing them. The need to make changes to the provisions of such international treaties and agreements as the World Trade Organization Agreements, the Recommendations of the World Organization for the Protection of Intellectual Property, the Oslo Guidelines, the UNCTAD Recommendations, and the framework program "Horizon Europe" has been proven.
The research was aimed at the formation of general theoretical foundations for the improvement of regulatory methods of identification of private law forms of technology transfer. The research results can be used in the formation of international normative acts, recommendations of international institutions, acts of national legislation and serve as a basis for further scientific research on these issues

Authors: Ivaniuk Khrystyna , Lesko Pavlo
Published: August 2024

The object of research is the donor-acceptor compound, organic and hybrid heterostructures based on it. The paper is focused on a comprehensive approach to solving the problem of the efficiency of light-emitting devices, finding new technological and design solutions for the use of organic compounds as multifunctional materials for various types of light-emitting devices.
The paper presents the multifunctional application of a planar 2D molecule as an emission layer for typical and inverted types of light-emitting heterostructures, as well as a matrix for a host-guest system using inorganic quantum dots. The developed light-emitting structures are characterized by external quantum efficiency typical for fluorescent devices, but good stability over the entire length of the consumption voltage. QLED brightness is 1600 cd·m-2 and EQE 1.4 %, which are good parameters for use in display technology.
Organic LEDs based on planar molecules are promising candidates for use in modern lighting systems. A separate advantage of these light-emitting structures is the multifunctionality of using one compound for different types of light-emitting structures, including inverted heterostructures. Special attention is paid to the technological and design implementation of invert structures, since their geometry allows direct connection to the back board of the n-channel transistor on the substrate. In addition, organic LEDs have low energy consumption and are environmentally friendly due to the absence of toxic substances in their architecture, which creates the prerequisites for saving energy resources and reducing the industrial burden on the environment.

A fundamentally new approach toverification and calibration of the on-board equipment of the radio beacon system for providing instrumental approach for an aircraft has been proposed, which consists of using directly radio beacons for these purposes that are in operation at existing airfields. Theoretically and experimentally, an original solution to the problem of checking and calibrating on-board equipment has been studied by generating landing radio signals with given values of the information parameter based on signals directly from the radio beacon and transmitting the generated signals through the surrounding space to the input of on-board receivers of the landing system. It is shown that commercially produced glide slope and localizer radio beacons of the decimeter wavelength range, supplemented by a signal combiner and a transmitting antenna with a radio frequency cable, will allow testing and calibration of on-board landing equipment with the accuracy that meets the requirements of GOST 15827–70. Monitoring the readings of the zero value of the information parameter on the indicator of the radio beacon system of the navigation and flight instrument by emitting signals from the glide slope radio beacon with a coefficient of inaudibility of signals equal to zero, has been experimentally confirmed when working with the short-range navigation radio system RSBN-2S and RSBN-PKV, which are part of AN aircraft –26Sh, TU-134Sh, TU-134UBL, located at the airfield in maintenance stops.

O mapa é um instrumento de poder, não estar no mapa significa ter sua existência apagada do mundo. Este artigo propõe reflexões acerca da potência existente na aproximação entre a psicologia comunitária, desde uma perspectiva de intervenções comunitárias e a cartografia social enquanto método de pesquisa. Para isso, aborda-se a simbologia do mapeamento, trazendo ao centro da análise o filme brasileiro Bacurau (2019) como interlocutor destas reflexões. A cartografia social como instrumento de construção de conhecimento coletivo possibilita uma aproximação com a comunidade, bem como a produção de pistas acerca das fragilidades e potências dos territórios por meio de diversas formas de elaboração de mapeamentos que encontram na escuta a oportunidade de leitura acerca da realidade social. Assim, cartografar em psicologia comunitária é uma forma de fazer existir no mapa e no mundo, através dos sons, imagens e narrativas que foram sendo silenciados na história das comunidades. Este artigo tem como uma das principais contribuições ao conhecimento em psicologia comunitária a compreensão de que a cartografia social é uma ferramenta teórico-metodológica essencial na formação de uma escuta e análise crítica em psicologia.

The impacts of risk perceptions and selection attributes on satisfaction based on demographic characteristics of tourists visiting Jeju: Focusing on the COVID-19 pandemic period
Authors:   The Tourism Sciences Society Of Korea, Kim Ki-Hyun , Lim Hwa-Soon
Published: August 2024

This study analyzed how tourists who visited Jeju during the COVID-19 pandemic differed in their behaviors and satisfaction based on demographic characteristics. Data (n=600) were collected through an online survey from February 22 to March 4, 2023. Analyses included independent sample t-tests, one-way ANOVA, and multiple regression analysis. Results showed variations in risk perceptions: the perceived risk of COVID-19 infection was higher among women than men and was highest among those in their 40s and 50s. Tourists who made more than four visits to Jeju perceived greater economic risk than others. In terms of selection attributes, tourists in their 20s and 30s or with frequent visits rated healing factors highly. Those vaccinated more than four times or with more than four visits to Jeju also rated COVID-19 safety factors highly. Economic risk negatively impacted satisfaction, while COVID-19 infection risk had a positive impact. Both healing and safety factors positively influenced satisfaction. The findings suggest that Jeju needs to prioritize hygiene and sanitation in tourism facilities and services in the 'New Normal Tourism (NNT)' era and develop segmented healing resources and wellness tourism products to be recognized as a leading healing tourism island in Korea. Additionally, to prevent potential tourists from choosing other destinations over Jeju, Jeju's image as an expensive destination needs to be addressed.

Specifically, this study examined how live commerce characteristics (i.e., real-time interactivity, playfulness, show host awareness, shopping convenience, price value, and presence), Technology Acceptance Model components (i.e., social influence and facilitating conditions), and flow lead to purchase intention. A total of 290 valid responses were collected via an online survey, targeting individuals who have watched live commerce for travel products. Results revealed that real-time interactivity, playfulness, and presence significantly impacted perceived usefulness, whereas show host awareness, shopping convenience, and price value did not. Furthermore, flow was significantly affected by real-time interactivity, playfulness, shopping convenience, price value, and presence but show host awareness had no impact. Perceived usefulness, flow, social influence, and facilitating conditions all significantly influenced purchase intention. Additionally, a significant moderating effect of gender was observed on the relationship between flow and purchase intention. The study offers several theoretical and practical implications for enhancing understanding and promoting travel products through live commerce.

Published: August 2024

This study applied the IPA(importance-performance analysis) methodology to unstructured text data to evaluate tourists' satisfaction levels with Incheon attractions. Focusing on attractions within the maintenance and improvement-needed areas identified by IPA, it extracted key positive and negative keywords and sentences directly from tourists' opinions. By applying a text-based approach to evolving IPA research, this exploratory study assessed the concrete satisfaction and dissatisfaction elements felt by tourists. The study limited its scope to 15 Incheon attractions and analyzed 114,007 sentences from Naver blogs written by tourists. Satisfaction levels were derived through deep learning sentiment analysis of the text, while the importance of each attraction was determined by the TF-IDF(term frequency-inverse document frequency) ratio of the attraction names in the text categorized by attributes such as attraction, transportation, activities, and food/drink. Key positive and negative keywords and sentences were extracted using the TextRank algorithm, focusing on attractions in the maintenance and improvementneeded areas. The findings reveal that experiential elements of attractions act as differentiating factors, while their absence can provoke negative reactions from tourists. Moreover, content reflecting local culture and history, the development of family-friendly experiential attractions, parking space expansion, and food service improvements emerged as crucial elements for attraction development.

Recently, there has been an increased interest in temple cuisine due to heightened consumer awareness of health and environmental issues. To establish a unique position as a tourist attraction, it is important to understand consumers' intentions and perceptions regarding temple food. Therefore, the aim of this study was to examine the relationship between the attributes of temple cuisine as a tourist resource and visitors' intentions to visit and recommend it. Additionally, the study investigated the mediating effects of consumers' perception of health value and environmental value on the relationship between temple food attributes and revisit and recommendation intentions. The research analyzed 358 consumers interested in temple food using structural equation and SPSS Process Macro analysis techniques. The results showed that consumers' perception of health value and environmental value mediate the relationship between temple food attributes and visit and recommendation intentions. Specifically, among those who had direct experience with temple cuisine, positive perceptions of environmental and health values were associated with higher intentions to visit and recommend. This study contributes by comprehensively examining the interrelationships and processes among temple food attributes, perceptions of health value, perceptions of environmental value, visit intentions, and recommendation intentions. Based on these findings, the study suggests the need for efforts from stakeholders to promote the positive attributes of temple cuisine, stimulate consumers' health and environmental value perceptions, and expand related institutions where consumers can experience temple cuisine. Ultimately, this can increase tourists' loyalty, visit intentions, and recommendation intentions.
A study on the tourism experiences of tourists with infants and young children from an accessible tourism perspective: Focusing on participants with experience in tourism activities
Authors:   The Tourism Sciences Society Of Korea, Lee Kyung-Chan , Chang Min-Hui
Published: August 2024

This study aimed to investigate the tourist experience of individuals who travel with infants and young children from the perspective of accessible tourism using online written interviews. Colaizzi's (1978) descriptive phenomenology was used as the research method, categorizing data into 6 categories, 17 theme clusters, and 73 themes. Specifically, the study examined reasons for participating in tourism, satisfaction with tourism activities, the usefulness of parents' prior experience, considerations when engaging in tourism with infants, difficulties encountered, and strategies for overcoming these difficulties. Difficulties and strategies for overcoming them were identified within the 17 theme clusters. The findings revealed that individuals participate in tourism activities to escape their daily routines, seek new experiences, and fulfill their parental roles. Although challenges such as limited mobility and lack of convenient facilities were noted, these were viewed as obstacles that could be easily overcome by the accompanying parents. This research highlights that individuals traveling with infants and young children perceive the limitations of tourism activities as unique conditions associated with traveling with young ones, differing from previous studies. Effective strategies for overcoming difficulties included diversifying information acquisition, engaging in actions to relax psychologically, and recognizing the uniqueness of the situation. Through this experiential process, parents were able to strengthen family bonds and derive satisfaction from the joy experienced by their children, resulting in a positive and fulfilling experience. These research findings contribute to a better understanding of the tourist experience for individuals traveling with infants and young children and offer important academic implications.

This study investigates the performance of roller compacted concrete (RCC) made with recycled aggregates derived from crushed demolished concrete with various proportions of natural. The experimental study examines substituting various proportions of natural aggregate (3/8, 8/15, and 15/20) with recycled aggregate. The replacement rates range from 0% to 100% in increments of 25%. Eleven different mixtures have been made by changing the amount of recycled aggregate used, with and without pre-wetting, before being added to concrete. Additionally, 5% of the cement content was substituted with silica fume and slag in each composition. An experiment test was done to see how recycled aggregate-based BCRs' performance changed with the incorporation rate on fresh and hardened concrete's mechanical and physical properties. Physical parameters, including volume masse, vebe time consistency, and mechanical properties such as compression resistance, flexion resistance, and ultrasonic pulse speed, were measured over time. The results found were compared to the control mix made with 100% natural aggregates. Those results show that as the replacement rate increases, the water absorption rate increases with a decrease in mechanical strength. In addition, the pre-wetting treatment did not significantly impact mechanical strength. This can be explained by the characteristics of the recycled aggregate, such as high absorption, low resistance to wear, and low density, which were caused by the residual paste adhered to the recycled aggregate.

Scholars studying online extremism and terrorism face major challenges, including finding safe access to hostile environments where members evade law enforcement. Protective measures, such as research ethics, often overlook the safety of investigators. Investigators, including Open-Source Intelligence (OSINT) analysts, encounter emotional harm, abuse from ideologues, consent issues, and legal challenges in data collection. Despite rising awareness of these challenges, scholars lack guidance on starting and navigating research in these areas. This paper identifies challenges and offers strategies for safely, ethically, and legally researching in this environment.
