Planerische Adressierung von Logistikflächen in der Raumordnung. Eine beispielhafte Auswertung (über)regionaler Raumordnungspläne
Authors: Thiemermann Andre
Published: February 2025

Currently, there are reasons for taking logistics up in spatial planning, including the large land consumption of logistics facilities and the urgent implementation of a sustainable transport system. One planning option is to secure suitable land for logistics facilities in formal spatial development plans. To date, only a limited number of studies have been carried out on this specific implementation. This paper uses 17 regional plans as examples to examine the planning instruments and planning focus with which this task is currently being implemented in German regional plans. The analysis of the regional plans at hand shows that half of the regional plans use planning instruments to address logistics facilities. In some regional plans, only defined logistics segments are addressed in planning, e.g. the establishment of port-related industries in the proximity of ports. To term land for logistics infrastructure like ports and inland terminals on the other hand, is much more established and is included in almost all plans. Taking up planning for locations of logistics facilities in regional plans takes place when logistics is defined as an economic focus, logistics is considered relevant for the functioning of the regional economy or planning locations for logistics facilities are required by state planning regulations.

Hadamard square of linear codes and the generalized minimal distance of Reed–Muller code of order 2
Authors: Chizhov Ivan V.
Published: February 2025

We propose a new technique for dimensional analysis of the Hadamard (Schur) square of an error-correcting linear code. This is usually achieved by a representation of the Hadamard square as an image of some linear operator defined on the set of quadratic forms. A link between the dimension of the Hadamard square the rank of some submatrix of the generating matrix of the code containing the set of vector values of quadratic forms is established. So the dimensional analysis of the Hadamard square can be carried out with the extensive code-based machinery rather than via the approach with estimation of the number of joint zeros of the set of quadratic forms. As a result and we establish a nonasymptotic estimate for the probability that the Hadamard square of a random linear code fills the entire space. This estimate can be used for cryptographic analysis of post-quantum code-based cryptosystems.

Authors: Saudan Quentin , Bekele Dagmawi A. , Xiong Meng , Yvind Kresten , Galili Michael , Mørk Jesper
Published: February 2025

We propose and experimentally demonstrate a small-mode volume bowtie cavity design for all-optical switching applications using a waveguide-cavity structure that exploits asymmetric Fano resonance lineshapes. The bowtie cavity has a mode volume that is five times smaller than conventional (H0-type) photonic crystal point-defect cavities enabling higher nonlinearity and faster switching. Blue and red-detuned Fano resonant devices based on bowtie cavity designs have been fabricated and characterized. Measured linear transmission spectra have been compared to coupled-mode theory models to extract key parameters such as Q-factors. Furthermore, all-optical switching at 2.5 Gbps have been demonstrated in a wavelength-conversion experiment.

Implicit Abandonment Distress: Testing the Dynamic Link Between Schema Activation and Physiological Arousal
Authors: Thomas Joel G. , Bogdan Paul C. , Katsumi Yuta , Dolcos Florin , Berenbaum Howard
Published: February 2025

Psychodynamic theory has been criticized as adhering to models of psychopathology that cannot lead to testable predictions and knowledge accumulation. To address this issue, we proposed an account of an implicit memory mechanism (a schema of abandonment) and measured the activation of this latent disposition in two meaningful contexts. Two hundred undergraduates were randomly assigned to either a social rejection or a comparison (non-reject) group, which was more ambiguous in nature. Explicit/implicit schema measures and psychophysiological data were used to test the relationship between schema activation and distress. As hypothesized, only the implicit schema measure was associated with physiological arousal; however, the nature of activation ran counter to our prediction. For participants with strong implicit abandonment schema content, significant arousal occurred in the comparison (non-reject) ambiguous group rather than the social rejection group. The findings demonstrate that: (1) implicit schema processes are indeed implicated in abandonment distress, and (2) situations in which the meaning of an event is more open to interpretation are likely more relevant to how schemas work. Altogether, findings suggest that psychodynamic processes are testable and may help account for distress dynamics, such as attempts to avoid real or imagined abandonment.
ОТ ЗНАНИЯ К ПОНИМАНИЮ
Authors: ШЕВЧЕНКО А.А.
Published: February 2025

В статье рассмотрены две основные эпистемические установки - знание и понимание, варианты их соотношения и динамика соответствующих представлений в современной эпистемологии и философии науки. Показано, что сдвиг интереса в сторону понимания произошел во многом вследствие неудовлетворенности классическим трехчастным определением знания и необходимостью реагировать на ситуации геттиеровского типа. Отдельно рассмотрена ситуация разрыва между знанием и пониманием - так называемая возможность «знания без понимания», уточнены отличительные характеристики и особенности понимания в познавательной деятельности, а также показаны опасности и возможные социальные последствия разрыва между знанием и пониманием

The article considers two main epistemic attitudes - knowledge and understanding, variants of their correlation and dynamics of the respective ideas in contemporary epistemology and philosophy of science. It is shown that the shift of interest towards understanding has largely occurred due to dissatisfaction with the classical three-part definition of knowledge and the need to respond to Gettier-type situations. The gap between knowledge and understanding, i.e. the so-called possibility of “knowledge without understanding”, is considered separately. The distinctive characteristics and features of understanding in cognitive activity are specified. The dangers and possible social consequences of the gap between knowledge and understanding are explicated
Genetic algorithm for structural adaptation of sorting algorithms
Authors:   Ukrainian State University of oScience and Technology, Shinkarenko V.I. , Makarov O.V. ,   Ukrainian State University of oScience and Technology
Published: February 2025

Constructivism was applied to form the sorting algorithm code. The meta-algorithm of program code generation is presented. Parts of existing sorting algorithms and auxiliary utilities are used for generation. A genetic algorithm was used to select the algorithm with the maximum time efficiency under the given conditions of use. The use of a standard genetic algorithm faces a problem associated with a different number of elementary sorting operations, which leads to the use of chromosomes of diff erent lengths. To solve the problem, a representation of the chromosome in the form of a binary tree is proposed. Each node has start genes, end genes, and two child nodes. To form an algorithm that is guaranteed to sort the array, all end nodes (leaves) include the final sorting gene at the end of the start genes sequence. This gene is decoded by calling the existing sorting algorithm, which is guaranteed to perform sorting. Crossover and mutation operations are performed on chromosomes in the form of a binary tree. Crossover is performed using the exchange of tree branches. Mechanisms of coding and decoding of the sorting algorithm from chromosome have been implemented. Decoding and formation of a suitable sorting algorithm is performed using linearization: formation of a textual representation using a depth-first tree traversal algorithm. The fitness function is defined as the average time of sorting randomly generated arrays for sorting (identical arrays for all chromosomes) in some stable environment, considering certain features of these arrays. It is possible to use other fitness functions related to the number of calculations, comparisons, or permutations. The developed software should be used for adaptation of sorting algorithms to stable input data streams and environments.

Published: February 2025

The difficulties associated with studying diffusion in multilayer films require the progress of contemporar y modeling methods and software platforms to precisely represent phenomena, taking into account transitions between adjacent layers. In addition to the indispensable role of advanced modeling techniques and software in solving the problems of studying diffusion in multilayer films, it is extremely important to admit the key contribution of sophisticated computational approaches. In this paper, the authors attempt to merge intricate mathematical models with optimal software development methodologies to address the challenge of simulating diffusion transport processes in multilayer nanofilms computationally. Based on the experimental findings and employing the suggested model, identification was conducted utilizing the theory of state control for multicomponent systems. With the help of methods of optimal control of the state of multicomponent transport systems, the analytical solution of the model and the data of experimental observations, the distributions of diffusion coefficients for the considered components of nanofilms (samples of aluminum, molybdenum, silicon) were reproduced. Numerical simulation results were compared with experimental observations. The profiles obtained from the modeling closely match the corresponding experimental profiles, especially as the duration of multilayer formation converges to the final stages of completing the protective nanofilm multilayer formation. The maximum observed deviation does not exceed 2–3%, confirming the reliability of the mathematical model and demonstrating the practical value of the results provided. A software framework is developed for the automation of the specified calculations with the possibility of extension to other subject areas with similar tasks of identifying the key factors of the process and further numerical modeling of the time-space characteristics using the obtained results.

Authors: Snow Kathleen D. , Mansbach Jonathan M. , Cortina Christopher , Berry Jay G. , Growdon Amanda S. , Stoeck Patricia A. , Walsh Kathleen
Published: February 2025

BACKGROUND AND OBJECTIVES

Boarding for pediatric mental health (MH) conditions is common at US children’s hospitals while patients await care at a psychiatric facility. We sought to describe recent trends in boarding encounters and to identify factors associated with prolonged length of stay.

METHODS

We performed a retrospective cross-sectional study analyzing pediatric MH boarding encounters at 40 tertiary children’s hospitals included in the Pediatric Health Information System database between January 1, 2017, and December 31, 2023. Children ages 3 to 18 presenting with a primary psychiatric diagnosis were included in the analysis. We assessed trends in boarding encounters and length of stay over time and analyzed variations in boarding practices among hospitals. Risk factors for prolonged boarding (≥9 days) were identified using mixed effects logistic regression models.

RESULTS

Between 2017 and 2023, there were 100 784 boarding encounters across 40 hospitals. Median length of stay for boarding encounters increased from 3 to 4 days (P < .001) and 350 (0.3%) children had stays of longer than 100 days. Boarding practices varied significantly by hospital site. Factors associated with prolonged boarding included older age, government insurance type, increasing medical complexity, specific psychiatric disorder, season of presentation, and discharge disposition to home.

CONCLUSIONS

Boarding while awaiting acute psychiatric care remains common, with a sustained increase in the volume of boarding encounters and length of stay since the onset of the COVID-19 pandemic. Patients with medical and/or psychiatric complexity may be more likely to experience prolonged boarding, highlighting an area for improved access to care.

Authors: Sanag-Rulona Emma
Published: February 2025

Research productivity in higher education institutions plays a vital role in achieving the goals of the institution. These institutions consider the teaching faculty as the primary producers of research in a university. Thus, it would be beneficial for the institution to find out the teaching faculty’s motivation to engage in academic research and determine the factors influencing their research productivity to enhance the institution’s efforts in cultivating quality and quantity research outputs. The study aims to investigate the research motivation, engagement, and research productivity of the college instructors at the University of Bohol. The researcher utilized a quantitative descriptive method using a researcher-made tool in which items were based on an intensive reading of theories, studies, and related literature. The tool underwent pretesting and possessed a high-reliability value based on its computed Cronbach a of .895. The respondents of the study were regular college instructors at the University of Bohol. The respondent’s profile, level of intrinsic and extrinsic motivation, level of research engagement, and status on research productivity were subjected to statistical treatment for analyses. The results show that respondents have higher intrinsic than extrinsic motivation. In addition, educational attainment was a consistent variable that significantly relates to the respondents’ research motivation, engagement, and productivity. The result implies that the level of research motivation, engagement, and research productivity level is dependent on one’s educational attainment. On the other hand, the factors that hindered the research engagement of the respondents were a lack of administration support and a full teaching load.

Objective. Optimization the surgical technique of percutaneous puncture endoscopic gastrostomy (PEG) in patients with a typical and subcostal stomach with negative diaphanoscopy. Material and methods. In the period from 2021 to 2023, we studied the results of performing PEG under ultrasound control using an endoscopic balloon in 29 patients: 23 (79.3%) patients with a typical stomach location and 6 (20.7%) patients with a subcostal location, in whom it was not possible to use diaphanoscopy and manual palpation to determine the location of the primary puncture the anterior abdominal wall and the wall of the stomach for the subsequent installation of a gastrostomy tube for the purpose of long-term enteral nutrition. Results. Technical and clinical success in our study was achieved in 100% of cases. There were no intraoperative complications. All patients were provided with enteral nutrition access through a gastrostomy tube. The surgical intervention time ranged from 20 to 40 minutes. The minimum period of hospitalization was 4 days, the maximum period was 7 days. In the early postoperative period, 2 (6.9%) patients had local inflammation of the postoperative wound in the area of the gastrostomy tube placement. These patients underwent local antibiotic therapy with a positive effect. Conclusion. PEG under ultrasound control using an endoscopic balloon in patients who cannot use diaphanoscopy to determine the location of the primary puncture is an effective, convenient and safe method of gastrostomy formation. This technique allows you to complete the PEG procedure without resorting to other methods of gastrostomy formation. Also, our proposed method provides the possibility of removing the stomach below the costal arch for the successful installation of PEG in patients with subcostal stomach.

Authors: Prokopyev S.A. , Mironov A.Yu.
Published: February 2025

Objective. Comparative evaluation of the duration of training and immediate results of treatment with videothoracoscopic (VATS) lobectomy via two-port access and open lobectomy in novice surgeons. Material and methods. The study included 118 surgical interventions performed in the thoracic department of AU RKOD of the Ministry of Health of the Chuvash Republic from January 2021 to February 2023. For comparative evaluation of the two learning curves, the operations were divided into two groups: the first group included VATS lobectomies performed via two-port access by a surgeon with initial zero experience in performing such operations (n=50) but with more than 5 years of experience in thoracic oncology; the second group included surgical interventions (n=68) performed by surgeons with less than 5 years of experience in thoracic surgery. Results. Evaluation of the learning curves showed that 31 operations were required to master VATS and 29 for open lobectomies, after which the duration of operations did not change significantly. The duration of surgery was longer in the VATS group (190 (150—230) min vs. 150 (122.5—175) min; p=0.0004). Blood loss was not statistically different in both groups (VATS 100 (50—200) ml, open lobectomy 75 (50—100) ml; p=0.42). The duration of drainage was shorter in the VATS group (6 (4—7) days vs. 7 (6—8) days; p=0.0000). The number of removed lymph nodes was higher in the thoracoscopic lobectomy group (11.5 (8.5—16) vs. 8.5 (7—12.5); p=0.01). Conclusion. The learning curves for VATS lobectomy and thoracotomy lobectomy are comparable. The level of competence and safety for performing standard lobectomies is achieved on average for both techniques after 30 operative procedures. However, significantly more operations are required to achieve mastery and to perform combined lobectomies.

Published: February 2025

Since the entire healthcare system operates in a dynamically changing and unpredictable environment, it requires strategic management. In order to achieve a socio-economic outcome in the context of Russian healthcare, state outpatient clinics will be the most important, as most goals and objectives can be achieved in an outpatient setting.The purpose of the study is a generalised assessment of the activities of all state outpatient medical institutions of the Russian Federation on key aspects of their activities in order to formulate a long-term development strategy for these institutions. This study uses the method of strategic analysis of the organisation's activities by means of PEST analysis. The PEST analysis was carried out with the participation of experts from various areas of the Russian Healthcare System.The results of the study. On the basis of the literature studied, the main factors that can influence the activities of the state polyclinic have been identified. These factors were selected by the author from a total of 40 questions and submitted for assessment by health professionals. Experts assessed the level of influence of the factor and the likelihood of the factor occurring in a state outpatient facility. On the basis of the estimates, a PEST analysis table has been compiled for the activities of governmental outpatient institutions. A weight-adjusted estimate is also calculated for each factor and a table of the influence of the factors in descending order is compiled. On the basis of this analysis, the main directions for the development of state outpatient medical institutions were formulated. The practical application of the results is possible in the conditions of the state outpatient medical service of the Russian Federation, since the main points of the development direction are formulated. The economic aspect of this study is the effective economic functioning of an outpatient institution based on a scientific approach in the field of strategic management. The originality and significance of this study lies in the fact that it conducts a PEST analysis in relation to state outpatient institutions of the Russian Federation, which has not been done before. The main scientifically based directions for the development of state outpatient medical institutions are also formulated.

Published: February 2025

The RFID Supermarket project was conceived with the idea of creating a therapeutic application that, using NFC technologies, functions like a real supermarket checkout. This allows residents in the CAPDs to practice tasks such as grocery shopping, differentiating objects by color, or following a recipe by scanning NFC tags. To achieve this, we developed an application in Android Studio capable of reading NFC tags. These tags serve to identify the different food items in the supermarket within our database. The application allows for flexible growth, as users can generate new lists and add additional items to the database, enabling continuous reuse and updates.
Modeling Energy Community Operations as a QUBO Problem for Quantum Optimization
Authors: Alonso Mateo , García-Santiago Xela , Rubiños Rodríguez Guillermo , Blázquez Gil Gonzalo
Published: February 2025

Energy communities are collectives that manage their own production, distribution, and consumption of energy, usually from renewable sources. To increase efficiency and sustainability, the scheduling of the loads on the basis of the user needs, the electricity prices, the availability of local renewable energy and the battery storage capacity must be optimized. Quantum computing, leveraging principles like superposition and entanglement, offers new computational power for complex optimization tasks. This paper lays the basis for exploring the potential of quantum computing in optimizing the operation of energy communities by modeling the problem as a Quadratic Unconstrained Binary Optimization (QUBO) problem.

Fascinating Application in Medicine Using Mixture Cure Models and Martingale Difference Correlation
Authors: Monroy-Castillo Blanca E. , Jácome Amalia , Cao Ricardo
Published: February 2025

Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease that leads to joint inflammation, functional disability, deformities, and reduced life expectancy. The goal of RA treatment is to achieve remission in the early stages of the disease, before permanent deformities develop. Therefore, identifying predictors of relapse is crucial, allowing physicians to tailor treatment plans. This need gives rise to the development of predictive models capable of processing large amounts of information and considering relapse of RA as the event of interest. Since not all individuals will experience this event, some will be classified as 'long-term survivors' or 'cured individuals.' Cure models enable direct modeling of the cure proportion and the effect of covariates on this proportion. This study introduces a new methodology to test the effect of covariates on patients who do not experience relapse, using a database provided by the Rheumatology-Health research group (GIR-S, by its acronym in Spanish).

Published: February 2025

Power supply is a key limitation when scaling supercomputing capabilities, making power consumption a major challenge in HPC field. To develop energy-efficient tools, it is essential to have an accurate power consumption modelling. Although previous works proposed several approaches to model CPU power, building models in an automated and adaptable way, and accurately predicting power, remains complex. This work presents two tools: CPUPowerWatcher, which gathers CPU metrics during the execution of user-defined workloads, and CPUPowerSeer, which build models to predict power from time series data. Using both tools, experiments were conducted to analyse the impact of novel factors on CPU power and compare the accuracy of six regression models when predicting CPU- and I/O-intensive workloads.

Authors: Ajmal Muhammad Zeeshan , Ahmed Mohamed Salah Adawi , Alsaeed Basel Khaled , Habib Nasir
Published: February 2025

Computer software protection presents complex and interrelated challenges, particularly in copyright and patent law. Developing countries in the Asia-Pacific region, including Pakistan, struggle with inadequate legal frameworks to safeguard both national and international software, exacerbated by the rapid evolution of software-related products and services. In contrast, China has made substantial progress in strengthening software protection through comprehensive copyright laws, regulatory measures, and inter-ministerial coordination frameworks that promote the use of legitimate software. These initiatives have significantly improved China's software copyright protection system, fostering the growth of its software industry. Furthermore, China's Patent Examination Guidelines provide a structured approach to software patentability, distinguishing between conventional software, which lacks patent protection, and innovative software, which qualifies for such protection. Given these advancements, Pakistan can benefit from implementing well-defined legal and administrative measures to enhance software protection. This study examines China’s current software protection policies, legislative and administrative frameworks, and their applicability to Pakistan, offering insights into potential legal reforms to strengthen software protection in the country.

Published: February 2025

Monitoring microclimate conditions, including temperature, humidity, and light intensity, is crucial for maintaining plant health and productivity in vertical indoor hydroponic systems. These conditions directly influence essential physiological processes such as photosynthesis and respiration, affecting growth and yield quality. Manual monitoring methods often suffer from inefficiencies such as slow data collection, operator dependency, and human error. This can delay responses to sudden microclimate changes, leading to plant stress and reduced productivity. This study aims to design a real-time microclimate monitoring and graphical interface system for indoor vertical hydroponics using a User-Centered Design (UCD) approach. The system integrates DHT11 and BH1750 sensors to measure temperature, humidity, and light intensity, respectively, with data processing performed using a Raspberry Pi 3 Model B+. The system performance was evaluated over 24 h using the root mean square error (RMSE) and accuracy metrics. Based on this analysis, the RMSE values for temperature, humidity, and light intensity were 2.398, 1.483, and 392.225, respectively, with an overall accuracy of 97.33%, demonstrating high reliability. Two interface prototypes, Design A and Design B, were developed using distinct visual approaches and evaluated by ten respondents across six criteria: appearance, color, layout, information, icon, and font. Design A outperformed Design B, achieving a higher average score (49 versus 43.4), reflecting its superior clarity and intuitive design. These findings highlight the potential of the proposed system to enhance microclimate management and optimize plant growth in indoor vertical hydroponics.

Background: Pneumonia is the most common health problem encountered during the Hajj pilgrimage and has been recognized globally as a major cause of morbidity, hospitalization and death. During the 2023 Hajj season, pneumonia is known to be among the top five diseases that cause hospitalization of elderly Indonesian Hajj pilgrims. Purpose: This research aimed to determine the risk factors for pneumonia in elderly Indonesian Hajj pilgrims. Methods: This research uses a cross-sectional study design with secondary data from the Integrated Hajj Computerized System for Health Sector (Siskohatkes) 2023. The population in this study was all elderly Hajj pilgrims recorded at Siskohatkes 2023 totaling 93,000 pilgrims. The sample used was 1,858 Hajj pilgrims aged ≥ 60 and hospitalized in Saudi Arabia. The data are analyzed at the multivariate level using the Cox Regression. Results: The study showed that the prevalence of pneumonia in elderly Indonesian Hajj pilgrims was 37.10% and the factor most significantly associated with the incidence of pneumonia was chronic obstructive pulmonary disease (COPD) comorbid (p-value <0.01; Adjusted PR= 1.43; 95%CI= 1.19–1.70). Conclusion: Comorbid COPD can increase the risk of elderly Hajj pilgrims being infected with pneumonia.

Introduction: Lead in the environment can be more easily absorbed by individuals with nutritional deficiencies, particularly breastfeeding mothers residing in agricultural areas near lead sources. Contaminated breast milk can disrupt infants' growth and development. This study aims to identify lead contaminants in the environment and assess the nutritional status of breastfeeding mothers to provide preventive measures. Methods: This cross-sectional study was conducted in the highland agricultural area of Semarang Regency in October 2021. Environmental samples, including air from agricultural land, settlements, groundwater, and raw food were carried out as environmental samples from 31 breastfeeding mothers. Dietary intake, haemoglobin, MCV, MCH, MCHC, and lead levels in breast milk was carried out. Lead content was analysed using ICP-OES. Geographic information system (GIS) was used to compare spatial distribution lead status levels with identified exposure factors. Results and Discussion: Median age of breastfeeding mothers was 24 years, with 72% being housewives, having a senior high school education. Median age of the infants was 2.5 months, 32% being boys, and 48% were exclusively breastfed. Mean hemoglobin level of the mothers was 13 ± 1.4 g/dL (13.8% was anemic) and median lead level in breast milk was 0.019 ppm. None of the mothers met their recommended macro- and micronutrient intake. Lead content in foods was 0.02-0.180 ppm, groundwater 0.017-0.034 ppm, and air 0-1.56 μg/Nm3 over a three-hours. Conclusion: The environment surrounding breastfeeding mothers contains lead, particularly in the air, and these mother experiences nutritional deficiencies, thereby increasing the risk of lead absorption.

Introduction: Domestic waste management, which is a provincial-level program, is expected to reduce greenhouse gas (GHG) emissions for the sustainability of climate control efforts in Indonesia. Given this context, it is necessary to conduct a carbon efficiency analysis in Indonesia based on domestic waste management efforts. Methods: This study used an observational research design with a cross-sectional time approach. This study predicted the reduction in carbon emissions based on domestic waste management using causal machine learning by analyzing data on GHG emissions and domestic waste management from all provinces in Indonesia. An advantage of causal machine learning is its ability to assess the impact of treatment (domestic waste management) on the results (GHG emissions), as well as mitigating the effects of confounding variables. Results and Discussion: Despite improvements in waste management, several provinces experienced increased waste production, particularly from domestic waste and plastic waste. Analysis using the R programming language revealed that waste management is a significant variable (p = 0.011). However, data limitations posed challenges to comprehensive analysis. Conclusion: Achieving carbon efficiency requires serious waste management efforts. All provinces and cities/regencies must actively participate in program implementation. Routine reporting is essential to monitor the progress toward reducing GHG emissions.

Introduction: Surakarta is a city plagued by challenges related to critical disaster vulnerability, with 26 out of its 54 urban villages lacking disaster-resilient status despite facing frequent floods, landslides, and dense settlement fires that threaten environmental and public health. Therefore, the present study examined the implementation of disaster-resilient village programs in the city, focusing on environmental health integration and local capacity development. Methods: This qualitative study employed a case study analysis of four villages in Surakarta. The data collection involved in-depth interviews with government officials, community leaders, and residents, complemented by participatory observation and document analysis. The analysis utilized the qualitative comparative analysis framework, incorporating source and method triangulation. Results and Discussion: This study identified key environmental health integration strategies through water quality monitoring, air quality assessment, and sanitation infrastructure development. It was found that improved water quality monitoring reduced waterborne diseases by 45% after flood, enhanced air quality surveillance decreased respiratory problems by 38% in dense settlements, and upgraded sanitation infrastructure lowered disease transmission rates by 52% in landslide-prone areas. Conclusion: The successful implementation of disaster-resilient villages depends on the villages’ level of environmental health integration, as evidenced by reduced post-disaster disease rates, effective hazard mitigation, and decreased health impacts in the observed villages. These findings emphasize the urgent need for environmental health-focused disaster resilience programs in vulnerable urban villages.

Introduction: One chemical substance used in producing epoxy resins and polycarbonate (PC) is called bisphenol-A (BPA). Three million tons of the chemical compound bisphenol-A are still produced annually. The amount of BPA produced in 2015 was 7.7 million tons; by 2022, 10.8 million tons are anticipated to be made. This study aimed to ascertain the effects of bisphenol-A exposure on human health. Discussion: This study used a systematic review method by collecting articles through online databases with a publication range of 2018 - 2024. The article search used the PRISMA flow diagram. The findings of 30 articles all examined the impact of BPA exposure on health. The level of exposure to bisphenol-A can have an impact on health due to the nature of BPA EDC (Endocrine Disrupting Hormone) which can inhibit the activity of natural hormones in the body. Conclusion: The impact on human health due to exposure to bisphenol-A such as cancer, obesity, disruption of reproductive health, hypertension, disrupting child development, and also behavioral changes in children. Bisphenol-A enters the body not only through food packaging but also through air and dust contaminated with BPA. The length of exposure and concentration of BPA affect its effects on the human body.

Published: February 2025

The second part of the history of the Institute of World Economy and World Politics was associated with the name of Valerian Obolenskii, better known under the literary double N. Osinskii. He was an old Bolshevik, a prominent state and party leader, one of the first Soviet Marxist economists. He joined the Institute at the beginning of 1926, and had been workings there for less than two years. Under his leadership, the Institute of World Economy expanded its staff and worked out the main areas of research. At the same time, the Institute began publishing of the “World Economy and World Politics” journal and completed the preparation of the Yearbook under the same name. Both the journal and the Yearbook soon gained international recognition and became the world’s first rate periodical analytical editions with economic and political specialization. The successful work of the Institute of World Economy was impeded not only by a small number of researchers, but also by the fact that its director worked there part-time. In 1926–1928, N. Osinskii was simultaneously the head of the Central Statistical Office (CSO), a member of the Soviet government – the Council of People’s Commissars of the USSR, which left him little time for full management of the Institute. This article prepared using archival sources examines the activities of the Institute of World Economy and World Politics headed by N. Osinskii (V. Obolenskii) in 1926 – early 1927.
The Taiwan Question as a Neocolonial Problem

Published: February 2025

The aggravation of the situation around the unrecognized state in Taiwan is interpreted by Western experts and politicians mainly in a simplified way: the United States is defending the island democracy from mainland authoritarian China. Their forecast boils down to determining the beginning of a supposedly inevitable military clash with one or another set of participants. Despite the fact that Western experts often characterize Chinese policy (in particular, economic policy) as neocolonial, the content of a number of US foreign policy documents gives grounds to conclude that their policy towards Taiwan is neo-colonialist, within the framework of which it serves as a geopolitical satellite and an important source of strategic goods for the neo-metropolis. Washington is seeking to build a stable system of political and economic relations, using not only direct pressure, but also privileges provided to partners that ensure both the military-political dominance of the United States and the uninterrupted supply of strategically important goods. In this context Taiwan can be described as one of the strongholds of US neocolonial policy. This policy has historically been rationalistic and situational in nature, invariably based on a certain understanding of the national interests of the United States, but does not always take into account the expectations of the Taiwanese regime. The results of the 2022 municipal elections, and then the 2024 presidential elections, demonstrated a split in Taiwanese society, which may have resulted in some way from contemplation of the consequences of a potential military conflict with the mainland. This circumstance, as well as the situation in Ukraine, which receives assistance from the United States, can become serious sobering and restraining factors for that part of society and the elite of Taiwan that shares the idea of independence of the island, which gives hope for the prospect of its peaceful reunification with China.
