Using artificial intelligence algorithms and computer image processing technology to improve environmental monitoring and protection methods in tourist destinations

ABSTRACT With the rapid development of the tourism industry, monitoring and protecting the environment of tourist destinations are facing increasingly severe challenges. Traditional environmental monitoring methods often rely on ground surveys, which suffer from problems such as incomplete data acquisition, slow response speed, and insufficient analytical capabilities, making it difficult to respond to complex ecological environment changes effectively. This article combined Support Vector Machine (SVM) and computer image processing technology to improve the efficiency and accuracy of environmental monitoring in tourist destinations. The image data collected in this article came from multiple areas within City A and was obtained between 2020 and 2022. The data type was remote sensing images. Vector machines were used to classify and analyse extracted data, achieving real-time monitoring and evaluation of environmental changes. The research results showed that this method performed well in identifying vegetation cover changes and monitoring water quality, significantly improving the timeliness of ecological data. The response speed increased from 403.5mbps to 582.1mbps. At the same time, the vegetation coverage rate in Area B of City A increased from 40%-70% to over 80%. This study provides a new technological path for environmental monitoring and protection in tourist destinations, which improves the comprehensive efficiency of monitoring and provides scientific data support for managers, thereby promoting the sustainable development of tourist destinations.

Intellectual Property Protection of Traditional Handicrafts: Practical Foundations and Future Perspectives

Traditional handicrafts, a tangible manifestation of traditional culture and a significant cultural legacy, its related intellectual property issues have been controversial in recent years. This paper evaluates several common methods of intellectual property protection that could be adapted to traditional handicrafts and the current state of protection. Then finds that the existing IP system lacks a systematic approach or framework to the protection traditional handicrafts. Although many countries have already experimented with the use of geographical indications for the protection of their national intangible cultural heritage, it is clear that the legitimate and reasonable protection approach of many traditional and indigenous cultural expressions cannot be achieved by means of single type of IP law. By drawing on the shortcomings and dilemmas of previous protection experiences and combining the characteristics of traditional cultural expressions, this paper proposes a fundamental mechanism for the protection of intellectual property rights for traditional handicrafts and a framework for underlying IP law protection.

FRONT-END SECURITY ARCHITECTURE: PROTECTION OF USER DATA AND PRIVACY

Investigation of this topic is relevant in light of the significant increase in the frequency and scale of cyber-attacks that affect various industries and organisations. The purpose of this study is to analyse existing data protection methods at the Front-end, which are able to effectively protect the confidentiality of user data in the face of modern cyber threats. Among the methods used, the analytical method, synthesis, classification, statistical and other methods should be noted. The study identified serious risks associated with storing confidential data on the client side. In particular, the use of cookies and local storage turned out to be vulnerable points that pose potential threats to data security. An analysis of existing web applications revealed the presence of cross-site scripting (XSS) vulnerabilities, which became a route for the introduction of malicious scripts. It was revealed that the generation and use of unique cross-site request forgery (CSRF) tokens for each request play a key role in preventing cross-site request forgery. The implementation of Governance as Code (GaC) technology has demonstrated potential for automating compliance with established architectural and security standards, thereby reinforcing front-end defenses against cyber threats. The findings emphasise the importance of educating end users on the basic principles of network security. The study highlights the importance of developers’ active involvement in Front-end security. Thus, a comprehensive overview of the Front-end security architecture with a focus on protecting user data and ensuring privacy is provided. The practical significance of the study lies in the provision of specific recommendations and practical solutions to improve Front-end security in web applications and represents a valuable set of tools and approaches that can be applied by developers and engineers to strengthen the security of web applications. The addition of Governance as Code technology introduces an innovative layer of automated security enforcement that is particularly suited to addressing emerging cybersecurity challenges in real-time.

Modern methods for protecting and storing data in computer systems to ensure their fault tolerance

The study's relevance stems from the fact that, in today’s world, where digital technologies permeate all areas of life and cyber threats continuously adapt, traditional methods of identifying critical vulnerabilities that rely on internal data often lag behind the evolution of these threats, leaving computer systems critically vulnerable. Ensuring the fault tolerance of computer systems is essential for stability and protection against such threats. The research methodology includes analyzing modern approaches to ensuring fault tolerance in relation to both hardware and software, utilizing cybersecurity models, redundancy, and data integrity at both the routing and system levels. Reliability was evaluated through theoretical analysis and application of existing technologies, as well as analysis of available system failure statistics based on open data sources. The main goal of the research was to develop recommendations and practical solutions to enhance the fault tolerance of computer systems through the integration of software and hardware protection methods based on an analysis of existing solutions. The task was to ensure system resilience to hardware-software failures before, during, and after their occurrence, thereby minimizing downtime of the hardware-software complex and data loss. The research demonstrated that a comprehensive approach provides the best protection, with the ability to identify issues before they arise. This includes component redundancy of both software and hardware types and the implementation of diagnostic and predictive failure systems. Systems equipped with modern anomaly detection methods can respond much faster to potential threats and minimize losses, while hardware systems with active monitoring and automatic switchover to backup components ensure continuity of processes in the event of critical technical failure. Future technologies, such as using artificial intelligence to analyze system state and predict potential failures, will significantly increase the efficiency and protection of hardware-software systems. However, they currently face compatibility challenges when combined with both legacy and new equipment, limiting their widespread adoption. The results of the research show that systems utilizing a hybrid monitoring approach, combining software and hardware protection, better adapt to changing operating conditions and demonstrate higher fault tolerance.

Patient and physician exposure to X-rays at pediatric interventional cardiology - from world to Poland.

Ionizing radiation is considered as a harmful factor to health. However, X‑rays are widely used in diagnostic and therapeutic procedures such as those performed during cardiac interventions. Their use is particularly invaluable in saving life procedures when the risk of adverse effects of radiation is relatively low compared to the consequences of non-treated or treated with other invasive methods diseases. One branch of these types of medical procedures is interventional cardiology in pediatrics due to possible higher than in adults risks of developing cancer in exposed to ionizing radiation children. On the other hand, medical staff in particular physician, may be exposed to relatively high radiation levels during their work. Parallel with enlarging workload (growing number of procedures per year), high levels of cumulative doses to most exposed, and often not protected, parts of operator's body as eye lenses and brain may be achieved. Exposure to X‑rays in pediatric interventional cardiology is a worldwide point of scientific interest from around 65 years, however assessment and simulating low level doses is still developing. In this review found data presents various trials of evaluating doses or levels of exposure to both medical staff and patient as well as methods of optimization and protection against X‑rays in pediatric cardiac interventional procedures. The issue of establishing diagnostic reference levels was also taken into consideration during analysis. Thirty papers from period 2013 to 2023 were analyzed. The main assumption of this condensed review is to reveal radiation protection methods worldwide and in Poland. Int J Occup Med Environ Health. 2024;37(6):569-80.

Mechanisms and Therapeutic Strategies for Myocardial Ischemia-Reperfusion Injury in Diabetic States.

In patients with myocardial infarction, one of the complications that may occur after revascularization is myocardial ischemia-reperfusion injury (IRI), characterized by a depleted myocardial oxygen supply and absence of blood flow recovery after reperfusion, leading to expansion of myocardial infarction, poor healing of myocardial infarction and reversal of left ventricular remodeling, and an increase in the risk for major adverse cardiovascular events such as heart failure, arrhythmia, and cardiac cell death. As a risk factor for cardiovascular disease, diabetes mellitus increases myocardial susceptibility to myocardial IRI through various mechanisms, increases acute myocardial infarction and myocardial IRI incidence, decreases myocardial responsiveness to protective strategies and efficacy of myocardial IRI protective methods, and increases diabetes mellitus mortality through myocardial infarction. This Review summarizes the mechanisms, existing therapeutic strategies, and potential therapeutic targets of myocardial IRI in diabetic states, which has very compelling clinical significance.

РОЗРОБКА ТА ВИРОБНИЦТВО ЛЕГКИХ ЛІТАЛЬНИХ АПАРАТІВ СІЛЬСЬКОГОСПОДАРСЬКОГО ПРИЗНАЧЕННЯ

Issues of protecting plants from diseases and pests are becoming more and more urgent. Climate change causes an increase in the activity of weedy plants and insects harmful to agriculture. Because of this, the chemical treatment of fields by aviation in modern agriculture should serve the purpose of preserving the future harvest in both a qualitative and quantitative sense. An important role in this is played by the biological method of plant protection, which is quite effective and environmentally friendly. It is based on the use of living organisms, their waste products and biologically active substances that regulate the development and reproduction of harmful plant organisms. Scientists have developed technologies for the breeding of such zoophages to protect plants from plant pests: Trichogramma, predatory mite Phytoseiulus, encarzia, Aphidimyza gallica, etc., as well as the production of microbiological preparations to protect plants from diseases and pests, the high efficiency of their use has been proven. Aircraft (planes, helicopters, ultralight aircraft) that are registered in the State Register of Civil Aviation Aircraft of Ukraine and have a certificate for the right to perform aerochemical work are allowed to carry out aerial work on the application of pesticides during agrochemical activities on agricultural and forest crops. The requirements for the characteristics of the aircraft, directive requirements for the technology of production, operation and maintenance of airworthiness were formulated. The evaluation of the manufacturability of the considered products (agricultural LA) cannot be evaluated without taking into account the operational manufacturability, which largely determines the costs when performing work in the field. Along with the requirements for the manufacturability of the aircraft design, the so-called operational requirements are of great importance. These requirements determine the suitability of the structure and equipment for its maintenance and repair during the operation of the aircraft, taking into account the high quality of work, the least consumption of time, labor and materials. Satisfying operational requirements ensures reliability, durability of the aircraft, high labor productivity during maintenance, reduction of operational costs and efficiency of use of the aircraft fleet. The appearance of the trichogram required the development of special means for its introduction. An attempt to use existing means showed their unsuitability due to their low functional efficiency and high cost of work. The task was solved by increasing the manufacturability of agricultural aircraft during their production and operation. This made it possible to organize its serial production and operation in many farms of the country.

Sun protection behaviors, healthcare access, and smoking among melanoma survivors.

Based on current clinical practice guidelines, melanoma survivors should be advised on the need for sun protection and regular healthcare, as well as smoking cessation, but differences from adults without cancer history are unclear. We pooled data from the National Health and Nutrition Examination Survey (2003-2006, 2009-2018), matching 249 melanoma survivors with 498 adults without a cancer history. Adjusted prevalence odds ratios (aPOR) and 95% confidence intervals (CI) were calculated. One-third of melanoma survivors used multiple sun protection methods, slightly more than adults without cancer. Both groups had < 50% overall sun protection use with long sleeves being the least used. Melanoma survivors who were male (aPOR = 2.91; CI = 1.05-8.06) or had lower education (aPOR = 4.12; CI = 1.65-10.29) were more likely to be current smokers. Older survivors (aPOR = 1.07; CI = 1.03-1.11) were more likely to have health insurance. Our findings highlight the relatively low use of sun protective practices for melanoma survivors and suggest the need for better counseling on sun protection and smoking cessation, especially for lower education levels and males. These findings underscore the importance of enhancing counseling services for sun protection among melanoma survivors and prioritizing smoking cessation support, especially for males and individuals with lower education levels among this population.

Efficient DNA Cryptography Using One-Time Pad and Run-Length Encoding for Optimized Ciphertext Storage

Cryptography ensures data privacy by transforming data into unreadable formats that only authorized individuals can decrypt. With the increase in electronically stored and transmitted data, enhanced methods for data protection are required. DNA cryptography, leveraging the genetic structure of DNA, provides a promising approach for secure communication and data storage. This paper introduces a novel DNA-based cryptographic method employing a DNA one-time pad (OTP) combined with modified run-length encoding to reduce ciphertext size. Unlike traditional cryptography, which often results in a larger ciphertext than plaintext, our proposed method demonstrates a significant reduction in ciphertext size. Experimental results reveal that for input text files of 1MB, 2MB, 3MB, 5MB, and 10MB, the ciphertext sizes were reduced by up to 20KB, 40KB, 60KB, 100KB, and 200KB, respectively. This reduction not only enhances storage efficiency but also minimizes transmission costs, marking a substantial advancement over existing DNA and classical cryptography methods. Future work will explore the application of this technique for encrypting biological data and incorporating DNA barcoding for improved data authentication and reliability.

Adaptive current protection for three‐phase short‐circuit faults in active distribution networks

AbstractTo address the impact of distributed generation (DG) access on the traditional protection configuration methods of distribution networks (DNs) and to facilitate the swift and effective protection of lines by protection devices under fault conditions, an adaptive current protection method for three‐phase short‐circuit faults in active distribution networks (ADNs), based on local information, is proposed. Initially, the applicability issues of traditional protection are examined, and the limitations of the existing protection scheme in ADNs are highlighted. Subsequently, the fault characteristics of ADNs are analysed, taking into account the output characteristics of DGs under short‐circuit faults, which form the foundation for the proposed protection method. Following this, an adaptive current protection method based on local information is introduced, utilizing a dual criterion of phase and magnitude to adjust line protection, with a specific implementation strategy for the protection scheme provided. Finally, the proposed protection scheme is validated using PSCAD/EMTDC simulation software, with results demonstrating that the scheme enables rapid and efficient protection action under fault conditions across the entire line.

Effects of Antifreeze Admixtures on Masonry Performance at Subfreezing Temperatures

Concrete brick prisms prepared with Type S masonry mortar that included sodium nitrite and/or nanocellulose as potential antifreeze admixtures were cured for 28 days at -10°C before measuring compressive and flexural bond strengths. Addition of sodium nitrite allowed masonry prisms cured at -10°C to reach 88% and 86% of the compressive and flexural bond strengths, respectively, of control specimens cured at room temperature. Nanocellulose was only effective when used in combination with sodium nitrite, improving the compressive and flexural bond strengths by an additional 3% and 27%, respectively. Results are primarily attributed to the ability of the sodium nitrite to lower the freezing point, allowing hydration to continue in subfreezing conditions, as confirmed by results of companion tests on mortar samples. Both additives also reduced the required w/c ratio and porosity. The findings offer a sustainable alternative to energy-intensive protective heating methods, potentially lengthening the construction season into colder periods.

Enhanced fault distance estimation for robust protection in unbalanced active distribution networks

Active Distribution Networks (ADN) have evolved significantly by integrating renewable energy sources. While these advancements have ushered in a more sustainable and efficient power system, these have also introduced challenges for traditional protection strategies. Conventional methods, often reliant on overcurrent relays, can struggle to adapt to the complexities of active distribution networks, where fault scenarios are diverse and dynamic. This paper identifies the limitations of conventional protection strategies and explores the redundancy concept applied to protection systems. To improve protection system reliability, an approach that overcomes these limitations using the advantages of distance protection is proposed here. The distance-based protection relay, traditionally employed in transmission networks, offers a promising redundancy solution for the challenges imposed by ADN. Considering the previous exposure, this paper introduces an algorithm for fault resistance and distance estimation designed to optimise the operation of distance relays in active distribution networks. The approach achieves remarkable accuracy with consistently low estimation errors for fault resistance and distance, regardless of fault type or distance. The proposed distance-based protection method is poised to revolutionise fault analysis in ADN, ultimately leading to faster fault isolation and more reliable and improved grid resilience.

Enhanced Kullback–Leibler Divergence Based Pilot Protection for Lines Connecting Battery Energy Storage Stations

In light of the challenges faced by existing protection methods when battery energy storage station (BESS) and various nonideal conditions emerge, enhanced Kullback–Leibler divergence-based time-domain pilot protection is put forward in this article. Given the discrepancy in current waveforms between internal and external faults, KLD is employed to quantify the degree of similarity between two current waveforms, enabling the accurate distinction between internal and external faults. To eliminate the asymmetry of KLD, improved KLD(IKLD) is introduced. Whereafter, a technique is proposed to convert the current sampling sequence into a probability distribution that can be utilized by IKLD. To counteract the negative influence of current transformer(CT) saturation on IKLD-based protection, the time-domain waveform features of summation current are adequately employed to develop an enhanced KLD(EKLD). Further, high and low thresholds are legitimately designed to ensure both dependability and security. The flowchart of EKLD-based pilot protection is described, and its effectiveness is extensively validated by variation in fault resistance, location, type and operating mode of BESS using PSCAD and a hardware-in-the-loop(HIL) testing platform. Additionally, proposed protection outclasses power frequency component-based current differential protection and some up-to-date presented time-domain protection methods.

Analysis on Towing Damage and Protection suggestions of Submarine Pipelines Caused by Ship Anchoring Operation

Abstract In this article towing damage of the anchor to the submarine pipeline is mainly studied, the magnitude of the towing force by using ABAQUS software is calculated, and the strength of the submarine pipeline is checked on the basis of the drag force. It is found that the damage to the pipeline caused by the drag is destructive, and the pipeline may fail, which may cause danger. This paper summarizes the calculation method of towing anchor navigation distance, and puts forward the pipeline protection method of setting no anchor area. From the point of view that the energy of the anchor can be absorbed by the soil, it is proposed that the pipeline can be buried to a certain depth to prevent the towing damage of the anchor to the submarine pipeline. The reference data are presented through a specific example. The research results can provide a theoretical basis and reference for the future research on the damage of submarine pipelines caused by towing and the protection methods of pipelines.
