Authors: Mironenko A.N.
Published: November 2024

The work is devoted to the development of a method for hiding information in a raster image using steganography together with cryptography. The proposed method allows solving the problem of restoring a message if the image containing hidden data has been damaged. The main idea is that the data using steganography are not placed in the image entirely, but using a (t, n) threshold scheme, with each part inserted independently. Software has been developed to test the proposed method. A series of experiments have been conducted to confirm the possibility of using the proposed method.

Principles of Building a Protocol for Guaranteed Message Delivery
Authors: Lavrov D.N.
Published: November 2024

As a rule, in computer networks information security is considered from the point of view of three properties: confidentiality, integrity and availability. Currently, it is important to consider such property of information as anonymity. To ensure the latter, a tool such as TOR is used. The TOR network gives us the illusion of anonymity on the Internet and lulls the vigilance of the end user. But at the output node of the TOR network, the traffic is decrypted and its contents may become known to the owner of this output node. If the owner of a node or a series of nodes is an authoritarian government, or a foreign agent, then he can not only know the contents of the message being transmitted, but also try to modify it or completely interrupt the communication channel. Confidentiality of the message can be protected by encryption, but one can only hope that it is secure. Accessibility and integrity remain at risk. Here, availability means a guarantee of delivering a complete message to a destination. The article discusses the principles that should be the basis of the data transfer protocol with guaranteed delivery. The idea of the protocol is based on the existence in the network of several independent delivery routes and the use of cryptographic (k,n)-threshold secret separation schemes in the n network flows of different routes. This will allow not only to further anonymize traffic, but also in the case of control by the authoritarian government of the output nodes (lower than k threshold) will provide additional protection for the confidentiality of traffic. \\\textit{This research was done as part of a research project NIOKTR number 01-06/683.}
CHAOTIC MASKING SCHEME FOR MESSAGES BASED ON ORTHOGONAL FUNCTIONS
Authors: Belim S.V. , RAKITSKIY Yu.S.
Published: November 2024

The method of chaotic masking of a discrete signal is proposed in the article. The proposed approach does not require the synchronization of chaotic generators and is resistant to noise in the communication channel. These properties remove the main problem of chaotic masking associated with the desynchronization of control parameters. The basic idea is to use message coding using orthogonal functions. Next, a simple summation of a hidden message with a chaotic signal is applied. The extraction of the message can be performed on the basis of the orthogonality property without subtraction of the chaotic component.

Authors: Li Dandan , Azman Nik Hadiyan Nik
Published: November 2024

The low-carbon economy is the major objective of China’s economy, and its goal is to achieve sustainable economic development. The study enriches the literature on the relationship between digital Chinese yuan (E-CNY), low-carbon economy, AI trust concerns, and security intrusion. The rapid growth of Artificial Intelligence (AI) offered more ways to achieve a low-carbon economy. The digital Chinese yuan (E-CNY), based on the AI technique, has shown its nature and valid low-carbon characteristics in pilot cities of China, it will assume important responsibilities and become the key link. However, trust concerns about AI techniques result in a limitation of the scope and extent of E-CNY usage. The study conducts in-depth research from the perspective of AI trust concerns, explores the influence of E-CNY on the low-carbon economy, and discusses the moderating and mediating mechanisms of AI trust concerns in this process. The empirical data results showed that E-CNY positively affects China’s low-carbon economy, and AI trust concerns moderate the positive impact. When consumers with higher AI trust concerns use E-CNY, their feeling of security intrusion is also higher. It affects the growth of trading volume and scope of E-CNY usage. Still, it reduces the utility of China’s low-carbon economy. This study provides valuable management inspiration for China’s low-carbon economy.

Authors: Mugambiwa Shingirai Stanley , Rakubu Kholofelo Annah
Published: November 2024

South Africa’s border posts are increasingly becoming crucial hubs for organized crime posing serious national and regional security implications with far-reaching consequences. The country’s national security, economic stability, and community safety are significantly jeopardised by organised criminal enterprises at border posts. As a result, the porous borders of South Africa have fostered an environment that is conducive to a variety of unlawful activities, such as the smuggling of drugs into the country and human trafficking. This paper seeks to identify political, economic, and social factors that lead to organised crime, corruption, and weak border management systems. The paper employed a secondary data analysis of existing scholarly articles, government reports as well as relevant case studies. The study found that local communities are most affected by illegal activities at the ports of entry. The findings further emphasize the importance of inclusive approaches in responding to security challenges that address cross-border flow regulation, fight corruption in service delivery, and promote community resilience. The paper concludes with recommendations for strengthening border controls towards enhancing cooperation between countries and curbing transnational crime networks.

Published: November 2024

This research examines intangible assets or intellectual capital (IC) performance of tourism-related industries in an underexplored area which is a tourism intensively-dependent country. In this study, VAIC which is a monetary valuation method and also the most widely applied measurement method, is utilized as the performance measurement method for quantifying IC performance to monetary values. Moreover, to better understand performance, the standard efficiency levels are further applied for classifying the performance levels of tourism industries. The sample sizes of study are 20 companies operating in the tourism-related industries in the world top travel destination or Thailand, and the companies’ data are collected from 2012 to 2021. Therefore, finally, there are 187 firm-year observations. The utilization of VAIC could assess IC performance of tourism firms and industries, and the standard efficiency levels further support the uniform interpretation of IC efficiency levels. The obtained results show the strong performance of both human and structural capital of the focused tourism dependent country especially in the logistics industry that directly supports and connects to the tourism attractions. Moreover, the finding also highlights the significance of human capital which plays as a major contributor for overall IC performance in this tourism dependent economy. This study contributes the new exploration of IC in the high impact industries and also specifically in the top significant tourism country. Moreover, the application of VAIC also confirms a practical application for management. The limited number of studied countries is a limitation of study. However, these new obtained data and information could be further applied for making comparisons or in-depth or statistical analysis in the future works.

Published: November 2024

The increasing use of the radiopharmaceutical Iodine-131 (I-131) in nuclear medicine services has implications for the potential for internal radiation received by workers. I-131 has high volatility so it has the potential to become an air contaminant and be inhaled by nuclear medicine staff as internal radiation exposure. This study aims to estimate I-131 contamination in staff at a nuclear medicine facility using a gamma spectrometer. Measurements of I-131 activity in the thyroid were carried out on 38 staff including medical physicists, nuclear medicine specialists, radiographers, radio-pharmacists, nurses, house attendants, and cleaners. The I-131 activity value measured in the staff's thyroid had an activity value range of 13.1 – 238.2 Bq in 13 nuclear medicine staff. Meanwhile, for 25 other medical staff, the I-131 activity values ??measured in the thyroid had activity values ??below the detection limit of the device (14.2 ± 4.3 Bq for men and 11.8 ± 3.5 Bq for women). The highest internal dose rate measured in the thyroid of Pramu Husada nuclear medicine staff and radiopharmaceuticals was 0.1-0.5 mSv/year. This value is still below the dose limit value for internal radiation.

Introduction: Polycythemia vera (PV) is a condition in which janus kinase 2 (JAK2) in hematopoietic cells experiences hyperactivation resulting in phosphorylation of signal transducer and activator of transcription 5 (STAT5) in the absence of a ligand binding to the receptor. This condition causes excessive production of blood cells, especially erythrocytes. The hyperactivation was caused by a V617F mutation in JAK2 which disrupted the interaction of the jak homology 1 (JH1) and jak homology 2 (JH2) domains. Polycythemia vera can cause complications such as thrombosis, hypertension, and splenomegaly. If prolonged, polycythemia vera can develop into myelofibrosis. In addition, JAK2 hyperactivation also causes an increase in phosphatidylinositol 3-kinase (PI3K) activity which also leads to STAT5 phosphorylation.
 
Discussion: Currently, the most widely used therapy for polycythemia vera is ruxolitinib. However, ruxolitinib has drawbacks, namely it cannot completely inhibit STAT5 phosphorylation and can increase the risk of reactivation of herpes zoster which can be inhibited by PI3K inhibitors. Therefore, an alternative therapy is needed, namely a combination of ruxolitinib with PI3K inhibitors, one of which is BEZ235. BEZ235 is a PI3K/Mammalian Target of Rapamycin (mTOR) inhibitor which has the potential to be combined with ruxolitinib. BEZ235 was able to prevent incomplete inhibition of STAT5 phosphorylation. However, BEZ235 has low bioavailability, so encapsulation efforts need to be made, one of which is by using CaCO3 nanocrystals. Overall, the combination of ruxolitinib with BEZ235 showed better results than the administration of the drug without the combination.
 
Conclusion: Therefore, the authors want to examine more deeply the potential of BEZ235 encapsulated CaCO3 nanocrystals combined with ruxolitinib for its potential as a therapy for polycythemia vera.

ABSTRACT
 
 
 
Introduction: Stress is a self-response, both physically and psychologically, to internal or external pressure. Many studies have shown that there is stress on teachers, including special education teachers in special schools for IDD’s students. Stress problems that occur related to teacher interpersonal communication with parents of students and teacher self-efficacy in teaching. This study aims to find out how the role of interpersonal communication and self-efficacy in teaching is related to the stress of special education teachers for IDD’s students at SLB Bali.
 
Method: The study used a quantitative approach and nonprobability sampling technique, with purposive sampling. The participants were 60 IDD’s special education teachers in three regions with the largest number of IDD’s special education teachers in Bali. The instruments in this study were the PSS-10 scale, the interpersonal communication scale, and the TSES scale.
 
Result: Multiple regression analysis showed that interpersonal communication and self-efficacy in teaching explained 69.3% of the variation in stress (F=62.427, p<0.001). Interpersonal communication and self-efficacy in teaching can reduce stress conditions.
 
Discussion: The research hypothesis is accepted, the independent variables support the dependent variables simultaneously or partially.
 
Conclusion: Interpersonal communication and self-efficacy in teaching can reduce the stress of special education teachers for IDD’s students at SLB Bali. The results of this study are expected to have theoretical and practical implications for related parties in efforts to reduce stress on special education teachers for IDD’s students.

Pendahuluan: Attention Deficit-Hyperactivity Disorder (ADHD) adalah gangguan psikiatri yang cukup umum terjadi dimana gangguan ini mempengaruhi fungsi kehidupan sehari-hari seseorang dengan beberapa kondisi, seperti kurangnya perhatian, hiperaktivitas, impulsivitas, dan sulit beristirahat.
Pembahasan: Pada beberapa anak, ADHD menetap hingga mereka tumbuh dewasa. ADHD memiliki beberapa dampak buruk pada orang dewasa dan dapat mempengaruhi kualitas hidup mereka secara signifikan. Orang dewasa dengan ADHD dilaporkan lebih berhubungan dengan pekerjaan yang tidak stabil, kurang beprestasi secara akademik, kecelakaan lalu lintas, perceraian, kriminalitas, dan gangguan penggunaan zat. Laki-laki dilaporkan memiliki prevalensi ADHD yang lebih tinggi dibandingkan perempuan. ADHD dapat disebabkan oleh beberapa faktor, seperti genetik, gangguan perkembangan saraf, cedera otak, dan komponen lingkungan. Mendiagnosis ADHD memberikan tantangan tersendiri karena banyaknya komorbiditas yang mengelilinginya, seperti gangguan bipolar, gangguan cemas, depresi, dan lain-lainnya, Terlebih lagi, beberapa orang dilaporkan mendapat diagnosis ADHD saat dewasa yang disebabkan oleh ketidaktepatan diagnosis sebelumnya. Terapi ADHD pada orang dewasa memerlukan terapi farmakologi, terbagi menjadi stimulan dan non-stimulan.
Simpulan: Mendiagnosis ADHD dengan segera, memberikan terapi yang tepat, dan menyediakan lingkungan yang empatik bagi pasien akan membantu mereka untuk mengatasi gejala yang dialami dan meningkatkan kualitas hidup.

Introduction: Superficial wound as a skin issue is commonly considered a trivial problem with minimal attention given, mainly for not being life threatening. However, when not given optimal care, superficial wound and mental health can create a vicious circle that may threaten physical and mental health. Therefore, skin regeneration and repair in order to optimize recuperation is a necessary topic to explore.
Discussion: Low-Level Laser Therapy (LLLT) has been considered one of the most effective ways in superficial wound treatment. Nevertheless, many practitioners are still unaware of its proper use that can potentially cause harm to patients. This review article outlines similarities between LLLT treatment and natural epidermal repair, LLLT mechanisms of action, and safe types and doses of LLLT used according to each type. Search is based on the latest literature studies that have been published previously.
Conclusion: LLLT is defined as an effective treatment due to its provision of local effect with no damage to other organs. This effectiveness is mainly due to its properties, namely monochromaticity, coherence, and polarization which will stimulate stem cell tissue proliferation. In addition, LLLT effectiveness depends on both laser factors and tissue properties which application of small doses on a regular basis will result to a more optimal treatment than infrequent use in larger doses. Safe and widely used LLLT types are Er:YAG, 46-Diode Cluster Probe, HeNe, and GaAIAs.

The coastline is defined as the location where water and land contact at any given time. Coastline change is considered as one of the most dynamic processes in coastal areas and is an indication of coastal accretion and erosion. The process of accretion and erosion can cause beach conditions to become unbalanced and even damaged. Cilacap Regency has a coastline of approximately 80 km which is directly adjacent to the Indian Ocean. The coast of Cilacap experienced changes in coastline which tended to be high from 1999-2008. For this reason, research has been carried out regarding coastline changes in Penyu Bay using remote sensing. The data used are Sentinel-1 and Sentinel-2 satellite images for 2016 and 2021. The analysis of shoreline changes uses the Digital Shoreline Analysis System (DSAS). The results of an analysis of shoreline changes in Penyu Bay from 2016 to 2021 show an average accretion of 1,278.49 m2 at Sentinel-1. While Sentinel-2 shows an average accretion of 2,917.68 m2. The average rate of line change per year on Sentinel-1 is 1 m/year with an indication of accretion and Sentinel-2 is 1,11 m/year with an indication of erosion. Accuracy test with Root Mean Square Error shows that Sentinel-1 is 36.80 m and Sentinel-2 is 15.43 m. Sentinel-1 has an accuracy value (CE90) of 55.84 m in class 2 with a scale of 1:100,000, while Sentinel-2 is 23.41 m in class 2 with a scale of 1:50,000.

Seagrass is aquatic ecosystems that is very beneficial for marine biota. One of the functions of seagrass fields is as a place to live, shelter, and place to find food for various types of fish. The correlation between seagrass and fish is very close, this study aims to decide the association between the abundance of the fish and the coverage of seagrass cover in Sanur, Bali. Samples were taken at two stations in Sanur which represented high seagrass cover, namely Sindhu Beach, and medium cover, namely Karang Beach. Data collection on seagrass cover and types was used in a 100 m line transect. The method that is used for taking the number and type of fish is using two methods, namely underwater visual census and beach nets. The results found eight species of seagrass, including Enhalus acoroides, Thalassia hemprichii, Syringodium isoetifolium, Cymodocea serrulata, Cymodocea rotundata, Halodule uninervis, Halodule pinifolia, and Halophila ovalis. Seagrass cover on Sindhu Beach is 72.2%, and Karang Beach is 50.2%. The fish found were 1,180 individuals, including 41 species from 18 families. The greatest abundance was in Sindhu Beach, which was dominated by Plotosus linneatus from the Plotosidae family, with a relative abundance of 30%, and the lowest abundance was on Karang Beach with the Plectorhinchus vittatus from the Haemulidae family, with a relative abundance of 0,2%. Diversity is worth 2.83, Variety is 0.80, and Dominance is 0.13. The correlation between fish abundance and seagrass cover is categorized as positive with a value of 0.8924 which indicated that a high seagrass cover has a high fish abundance and vice versa.
