A Vision Dynamics Learning Approach to Robotic Navigation in Unstructured Environments
Authors: Ginerica Cosmin , Zaha Mihai , Floroian Laura , Cojocaru Dorian , Grigorescu Sorin
Published: January 2024

Autonomous legged navigation in unstructured environments is still an open problem which requires the ability of an intelligent agent to detect and react to potential obstacles found in its area. These obstacles may range from vehicles, pedestrians, or immovable objects in a structured environment, like in highway or city navigation, to unpredictable static and dynamic obstacles in the case of navigating in an unstructured environment, such as a forest road. The latter scenario is usually more difficult to handle, due to the higher unpredictability. In this paper, we propose a vision dynamics approach to the path planning and navigation problem for a quadruped robot, which navigates in an unstructured environment, more specifically on a forest road. Our vision dynamics approach is based on a recurrent neural network that uses an RGB-D sensor as its source of data, constructing sequences of previous depth sensor observations and predicting future observations over a finite time span. We compare our approach with other state-of-the-art methods in obstacle-driven path planning algorithms and perform ablation studies to analyze the impact of architectural changes to our model components, demonstrating that our approach achieves superior performance in terms of successfully generating collision-free trajectories for the intelligent agent.

Published: January 2024

Underground coal-mining-induced ground subsidence deformation is a common geological disaster impacting buildings, transportation and water supplies. Models predicting ground subsidence dynamically with high precision are important for the prevention of damage derived from ground subsidence. In this paper, the Hook function is utilized to develop a model describing the velocity of ground subsidence due to underground coal mining. Based on the subsidence velocity model, a dynamic subsidence model is established by taking an integral of the velocity model. Coefficients of the model, which depend on maximum subsidence, maximum subsidence velocity and the time corresponding to the maximum subsidence velocity, are related to the geological and mining conditions of the coal seam being investigated. A Levenberg–Marquardt-algorithm-based method is also proposed to calculate the optimal model coefficients based on subsidence velocity observations. Four continuously operating Global Navigation Satellite System (GNSS) stations were constructed above a typical longwall coal mining working face in the Jining mining area, China. These GNSS stations collected subsidence observations over two years, which were used to validate the developed prediction model. The results show that the root-mean-square (RMS) of the model-predicted ground subsidence error is 56.1 mm, and the maximum relative error is 2.5% for all four GNSS stations, when the ground subsidence is less than 6000 mm.

Authors: Cheng Yi-Lin , Yeh Wen-Hsiang , Liao Yu-Ping
Published: January 2024

During the COVID-19 pandemic, the number of cases continued to rise. As a result, there was a growing demand for alternative control methods to traditional buttons or touch screens. However, most current gesture recognition technologies rely on machine vision methods. However, this method can lead to suboptimal recognition results, especially in situations where the camera is operating in low-light conditions or encounters complex backgrounds. This study introduces an innovative gesture recognition system for large movements that uses a combination of millimeter wave radar and a thermal imager, where the multi-color conversion algorithm is used to improve palm recognition on the thermal imager together with deep learning approaches to improve its accuracy. While the user performs gestures, the mmWave radar captures point cloud information, which is then analyzed through neural network model inference. It also integrates thermal imaging and palm recognition to effectively track and monitor hand movements on the screen. The results suggest that this combined method significantly improves accuracy, reaching a rate of over 80%.
Enhancing Smart Building Surveillance Systems in Thin Walls: An Efficient Barrier Design
Authors: Lee Taewoo , Kim Hyunbum
Published: January 2024

This paper introduces an efficient barrier model for enhancing smart building surveillance in harsh environment with thin walls and structures. After the main research problem of minimizing the total number of wall-recognition surveillance barriers, we propose two distinct algorithms, Centralized Node Deployment and Adaptation Node Deployment, which are designed to address the challenge by strategic placement of surveillance nodes within the smart building. The Centralized Node Deployment aligns nodes along the thin walls, ensuring consistent communication coverage and effectively countering potential disruptions. Conversely, the Adaptation Node Deployment begins with random node placement, which adapts over time to ensure efficient communication across the building. The novelty of this work is in designing a novel barrier system to achieve energy efficiency and reinforced surveillance in a thin-wall environment. Instead of a real environment, we use an ad hoc server for simulations with various scenarios and parameters. Then, two different algorithms are executed through those simulation environments and settings. Also, with detailed discussions, we provide the performance analysis, which shows that both algorithms deliver similar performance metrics over extended periods, indicating their suitability for long-term operation in smart infrastructure.

Authors: Pérez-Varela Yolanda , Cárdenas-Rodríguez Rocío
Published: January 2024

Education is considered to be one of the most critical factors when it comes to finding work or starting a business. However, for women migrants, other factors can have an even more decisive influence, since they are starting out with the double disadvantage they face as women and migrants. This manuscript sets out to identify and analyse the individual and external factors that affect the employability and entrepreneurship of women migrants. To do this, we conducted a systematised qualitative review of recent literature. The studies analysed address different aspects of integration and employment but agree on many of the factors that hinder employability and entrepreneurship, such as traditional gender mandates, racism, socioeconomic status, the migration process, age or human capital. However, the scientific literature continues to mask the reality of women migrants who face discrimination or inequalities derived, for example, from their belonging to the LGBTQ+ collective or their functional diversity.

Published: January 2024

This research-to-practice article delves into novel learning experiences for operations management education, involving the circular economy and experiential learning. Higher Education academics are required to develop effective learning that actively and impactfully helps nurture in students the essential competency to face sustainable development demands. In operations management education, one possibility is to integrate real-world circular economy challenges into learning activities that address issues concerning solid waste generation in business processes and operations. This type of innovative learning experience involves both conceptual understanding and practical implementation. Accordingly, experiential learning is considered a suitable pedagogy for this purpose in this work because of its hands-on applications, critical thinking, and active engagement. To illustrate this proposition, this paper presents a case study concerning an operations management undergraduate course at a Mexican university. The case study indicates how to translate a situation of solid waste generation in a business into relevant disciplinary experiential learning. The results show that students regarded the learning experience as motivating, interesting, and relevant while widely accomplishing their learning objectives. However, limitations did exist regarding experiential learning, the methodological approach, data collection, and implementation challenges. Future work points to the need for further learning experiences and to improve research reliability, transferability, and validity.

Published: January 2024

The global food system is currently facing significant challenges that make it unsustainable and environmentally harmful. These challenges not only threaten food security but also have severe negative impacts on the environment. Efforts have been made to reform agrifood systems and align them with the built environment, but emerging obstacles have revealed the weaknesses in these systems, particularly in less self-sufficient countries. This review outlines the primary environmental problems associated with global agrifood systems and the challenges in promoting food security. It emphasizes that the increasing global population and urbanization need rational and equitable changes in food systems, including production, distribution, storage, and consumption. These changes should aim to minimize environmental impacts by protecting and efficiently utilizing natural resources such as air, water, soil, and biodiversity, reducing food loss and waste, and mitigating pollution that contributes to ecosystem degradation and climate change. In this context, hydroponics emerges as a sustainable, plant-based food production technique that can be employed as a solution in urban areas. It can be implemented in domestic microproduction systems, serving as a complementary alternative to conventional food production methods. This study also provides insights into the challenges that need to be addressed in order to enhance home hydroponic systems. The integration of hydroponics into urban food production offers the potential to tackle both food security and environmental sustainability issues, providing a path toward more resilient and efficient food systems.

Published: January 2024

As climate change influences flood frequency, transportation damage and disruptions will become more common. Given the network’s expanse and cost of construction, communities’ mitigation efforts should be informed by analyses that span normal conditions and disaster management phases. This paper analyzes road segment criticality in normal, flood response, and recovery phases in Anderson County, South Carolina, considering impacts on emergency services, healthcare, industry, education, recreation, and transit. A 100-year event provides context for analyzing flood impacts to the time-based shortest paths, determined using ArcGIS Pro 3.1.3. Local and secondary roads were especially affected, with rerouting concentrating around the Anderson City area. Blocked road sections identified potentially vulnerable roads, and normalized betweenness centrality metrics identified community dependence on road segments for daily and emergency operations. While the quantity and dispersion of parks and grocery stores mitigated rerouting distance, other purposes faced challenges from impassable routes. The analysis revealed the southeastern and southern regions as most impacted across purposes, suggesting targeted mitigation. I-85, State Routes 28 and 81, and Federal Routes 29, 76, and 178 were the most critical roads before, during, and after the flood. This study highlights commonalities in road criticality across phases to support resilient transportation planning and sustainability.

Published: January 2024

(1) Background: An asthma exacerbation that is not relieved with medication typically requires an emergency room visit (ERV). The coronavirus disease 2019 (COVID-19) pandemic began in Taiwan in January of 2020. The influence of the COVID-19 pandemic on pediatric ERVs in Taiwan was limited. Our aim was to survey pediatric asthma ERVs in the COVID-19 era; (2) Methods: Data were collected from the health quality database of the Taiwanese National Health Insurance Administration from 2019 to 2021. Air pollution and climatic factors in Taipei were used to evaluate these relationships. Changes in the rates of pediatric asthma ERVs were assessed using logistic regression analysis. Poisson regression was used to evaluate the impact of air pollution and climate change; (3) Results: The rate of pediatric asthma ERVs declined in different areas and at different hospital levels including medical centers, regional and local hospitals. Some air pollutants (particulate matter ≤ 2.5 µm, particulate matter ≤ 10 µm, nitrogen dioxide, and carbon monoxide) reduced during the COVID-19 lockdown. Ozone increased the relative risk (RR) of pediatric asthma ERVs during the COVID-19 period by 1.094 (95% CI: 1.095–1.12) per 1 ppb increase; (4) Conclusions: The rate of pediatric asthma ERVs declined during the COVID-19 pandemic and ozone has harmful effects. Based on these results, the government could reduce the number of pediatric asthma ERVs through healthcare programs, thereby promoting children’s health.

Published: January 2024

Plastic pollution is a pressing global issue, prompting the exploration of sustainable alternatives such as bioplastics (BPs). In agriculture, BPs have gained relevance as mulching films. This study investigated the effect of the presence in the soil of different concentrations (0–3%, w/w) of a corn starch-based bioplastic on basil (Ocimum basilicum L.). The results showed that increasing bioplastic concentration reduced shoot fresh biomass production. Biochemical analyses revealed changes in the shoot in soluble protein content, biomarkers of oxidative and osmotic stress (malondialdehyde and proline, respectively), anti-radical activity, and antioxidant compounds (phenols, flavonoids, and ascorbic acid), which are indicative of plant adaptive mechanisms in response to stress caused by the presence of the different concentrations of bioplastic in the soil. Macro- and micronutrient analysis showed imbalances in nutrient uptake, with a decreased content of potassium, phosphorus, and manganese, and an increased content of magnesium, iron, and copper in the shoot at high BP concentrations.

Published: January 2024

Despite significant improvements in air quality during and after COVID-19 restrictions, haze continued to occur in Zhengzhou afterwards. This paper compares ionic compositions and sources of PM2.5 before (2019), during (2020), and after (2021) the restrictions to explore the reasons for the haze. The average concentration of PM2.5 decreased by 28.5% in 2020 and 27.9% in 2021, respectively, from 102.49 μg m−3 in 2019. The concentration of secondary inorganic aerosols (SIAs) was 51.87 μg m−3 in 2019, which decreased by 3.1% in 2020 and 12.8% in 2021. In contrast, the contributions of SIAs to PM2.5 increased from 50.61% (2019) to 68.6% (2020) and 61.2% (2021). SIAs contributed significantly to PM2.5 levels in 2020–2021. Despite a 22~62% decline in NOx levels in 2020–2021, the increased O3 caused a similar NO3− concentration (20.69~23.00 μg m−3) in 2020–2021 to that (22.93 μg m−3) in 2019, hindering PM2.5 reduction in Zhengzhou. Six PM2.5 sources, including secondary inorganic aerosols, industrial emissions, coal combustion, biomass burning, soil dust, and traffic emissions, were identified by the positive matrix factorization model in 2019–2021. Compared to 2019, the reduction in PM2.5 from the secondary aerosol source in 2020 and 2021 was small, and the contribution of secondary aerosol to PM2.5 increased by 13.32% in 2020 and 12.94% in 2021. In comparison, the primary emissions, including biomass burning, traffic, and dust, were reduced by 29.71% in 2020 and 27.7% in 2021. The results indicated that the secondary production did not significantly contribute to the PM2.5 decrease during and after the COVID-19 restrictions. Therefore, it is essential to understand the formation of secondary aerosols under high O3 and low precursor gases to mitigate air pollution in the future.

Published: January 2024

Tuberculosis Preventive Treatment (TPT) is a powerful tool for preventing the TB infection from developing into active TB disease, and has recently been expanded to all household contacts of TB cases in India. This study employs a mixed-methods approach to conduct a situational analysis of the initial phase of TPT implementation among household contacts of pulmonary TB patients in three districts of Delhi, India. It was completed using a checklist based assessments, care cascade data, and qualitative analysis. Our observations indicated that organizational structure and planning were established, but implementation of TPT was suboptimal with issues in drug availability and procurement, budget, human resources, and training. Awareness and motivation, and shorter regimen, telephonic assessment, and collaboration with NGOs emerged as enablers. Apprehension about taking TPT, erratic drug supply, long duration of treatment, side effects, overburden, large population, INH resistance, data entry issues, and private provider reluctance emerged as barriers. The study revealed potential solutions for optimizing TPT implementation. It is evident that, while progress has been made in TPT implementation, there is room for improvement and refinement across various domains.
Influenza A Virus and Acetylation: The Picture Is Becoming Clearer
Authors: Husain Matloob
Published: January 2024

Influenza A virus (IAV) is one of the most circulated human pathogens, and influenza disease, commonly known as the flu, remains one of the most recurring and prevalent infectious human diseases globally. IAV continues to challenge existing vaccines and antiviral drugs via its ability to evolve constantly. It is critical to identify the molecular determinants of IAV pathogenesis to understand the basis of flu severity in different populations and design improved antiviral strategies. In recent years, acetylation has been identified as one of the determinants of IAV pathogenesis. Acetylation was originally discovered as an epigenetic protein modification of histones. But, it is now known to be one of the ubiquitous protein modifications of both histones and non-histone proteins and a determinant of proteome complexity. Since our first observation in 2007, significant progress has been made in understanding the role of acetylation during IAV infection. Now, it is becoming clearer that acetylation plays a pro-IAV function via at least three mechanisms: (1) by reducing the host’s sensing of IAV infection, (2) by dampening the host’s innate antiviral response against IAV, and (3) by aiding the stability and function of viral and host proteins during IAV infection. In turn, IAV antagonizes the host deacetylases, which erase acetylation, to facilitate its replication. This review provides an overview of the research progress made on this subject so far and outlines research prospects for the significance of IAV-acetylation interplay.

Published: January 2024

Sever Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is still a threat to human health globally despite the World Health Organization (WHO) announcing the end of the COVID-19 pandemic. Continued surveillance of SARS-CoV-2 at national borders would be helpful in understanding the epidemics of novel imported variants and updating local strategies for disease prevention and treatment. This study focuses on the surveillance of imported SARS-CoV-2 variants among travelers entering Xiamen International Airport and the Port of Xiamen from February to August 2023. A total of 97 imported SARS-CoV-2 sequences among travelers from 223 cases collected from 12 different countries and regions were identified by real-time RT-PCR. Next-generation sequencing was used to generate high-quality complete sequences for phylogenetic and population dynamic analysis. The study revealed a dominant shift in variant distribution, in which the XBB subvariant (XBB.1.5, XBB.1.16, XBB.1.9, XBB.2.3, and EG.5.1) accounted for approximately 88.8% of the sequenced samples. In detail, clades 23D and 23E accounted for 26.2% and 21.4% of the sequenced samples, respectively, while clades 23B (13.6%) and 23F (10.7%) took the third and fourth spots in the order of imported sequences, respectively. Additionally, the XBB.2.3 variants were first identified in imported cases from the mainland of Xiamen, China on 27 February 2023. The spatiotemporal analyses of recent viral genome sequences from a limited number of travelers into Xiamen provide valuable insights into the situation surrounding SARS-CoV-2 and highlight the importance of sentinel surveillance of SARS-CoV-2 variants in the national border screening of incoming travelers, which serves as an early warning system for the presence of highly transmissible circulating SARS-CoV-2 lineages.

Authors: Gustafsson Lina , Wikström Camilla , Mueller Ralf S. , Bergvall Kerstin
Published: January 2024

Clipping hair on animals can produce microtraumas of the skin and the dislodgement of microorganisms to the clipper blade. This study evaluates if clipper blades in animal hospitals in Sweden are contaminated with bacteria and/or dermatophytes after disinfection. Eleven clipper blades from three veterinary referral hospitals, including one with a small animal department and an equine department, were sampled for bacteria and dermatophytes. All the hospitals had disinfection routines in accordance with the national recommendations for hygiene in veterinary medicine. The sampled clipper blades were supposed to be disinfected and they were considered to be ready for use by staff. Five sterilized clipper blades were used as controls. The results showed that 64–100% of the disinfected clipper blades, from all three hospitals, were contaminated with bacteria, whereas all the sterilized clipper blades were negative for bacterial growth (p < 0.05). One clipper blade from the equine department was contaminated with dermatophytes. The results indicate that the disinfection routines were not sufficient for removing bacteria from used clipper blades, and that sterilization would be a more reliable way to minimize the risk of contamination.

Published: January 2024

The reliable observation and accurate estimates of land–atmosphere water vapor (H2O) flux is essential for ecosystem management and the development of Earth system models. Currently, the most direct measurement method for H2O flux is eddy covariance (EC), which depends on the development of fast-response H2O sensors. In this study, we presented a cost-efficient open-path H2O analyzer (model: HT1800) based on the tunable diode laser absorption spectroscopy (TDLAS) technique, and investigated its applicability for measuring atmospheric turbulent flux of H2O using the EC method. We prepared two HT1800 analyzers with lasers that operate at wavelengths of 1392 nm and 1877 nm, respectively. The field performance of the two analyzers was evaluated through inter-comparative experiments with LI-7500RS and IRGASON, two of the most commonly used H2O analyzers in the EC community. Water vapor densities measured by the three types of analyzers had high overall agreement with the reference sensor; however, they all experienced drift. The mean density drifts of HT1800, LI-7500 and IRGASON were 3.7–5.2%, 4.0% and 3.8%, respectively. Even so, the half-hourly H2O fluxes measured by HT1800 were highly consistent with those by LI-7500RS and IRGASON (with a difference of less than 2%), suggesting that HT1800 can obtain H2O fluxes with high confidence. The HT1800 was also proved to be suitable for EC application in terms of data availability, flux detection limit and response to the high-frequency turbulent variation. Furthermore, we investigated how the spectroscopic effect influences the measurements of H2O density and flux. Despite the fact that the 1392 nm laser was much more susceptible to the spectroscopic effect, the fluxes after correcting for this bias showed excellent agreement with the IRGASON fluxes. Considering the cost advantage in laser and photodetector, the HT1800 analyzer using a 1392 nm infrared laser is a promising and economical solution for EC measurement studies of water vapor.

Published: January 2024

Understanding and modeling water quality in a lake/reservoir is important to the effective management of aquatic ecosystems. The advantages and disadvantages of different water quality models make it challenging to choose the most suitable model; however, direct comparison of 1-D and 3-D models for lake water quality modeling can reveal their relative performance and enable modelers and lake managers to make informed decisions. In this study, we compared the 1-D model MINLAKE and the 3-D model EFDC+ for water temperature, ice cover, and dissolved oxygen (DO) simulation in three Minnesota lakes (50-m Carlos Lake, 23.5-m Trout Lake, and 5.6-m Pearl Lake). EFDC+ performed well for water temperature and DO simulation in the open water seasons with an average root mean square error (RMSE) of 1.32 °C and 1.48 mg/L, respectively. After analyzing the ice thickness with relevant data, it was found that EFDC+ calculates a shorter ice cover period and smaller ice thickness. EFDC+ does not consider snowfall for ice thickness simulation. The results also revealed that EFDC+ considers spatial variance and allows the user to select inflow/outflow locations precisely. This is important for large lakes with complex bathymetry or lakes having multiple inlets and outlets. MINLAKE is computationally less intensive than EFDC+, allowing rapid simulation of water quality parameters over many years under a variety of climate scenarios.

Du lịch nông nghiệp đóng vai trò quan trọng nhằm nâng cao thu nhập của người dân và thúc đẩy phát triển nông thôn bền vững.  Nghiên cứu nhằm đánh giá việc sử dụng công nghệ thông tin hiện nay trong quản lý, tiếp thị và bán hàng tại các trang trại và hợp tác xã du lịch nông nghiệp ở tỉnh Thái Nguyên. Nghiên cứu sử dụng phương pháp gồm khảo sát và phỏng vấn trực tiếp, được thực hiện trên tám cơ sở du lịch nông nghiệp ở bốn khu vực của tỉnh Thái Nguyên. Kết quả cho thấy công nghệ thông tin đang được các cơ sở áp dụng, mặc dù có một số hạn chế nhất định. Chỉ có ba trang trại sở hữu các trang web chuyên dụng trong đó một đơn vị cập nhật nội dung một cách nhất quán. Nghiên cứu cho thấy chỉ có 7,08% khách du lịch biết các trang trại nông nghiệp ở tỉnh Thái Nguyên thông qua trang web. Một khuyến nghị từ khách du lịch là các trang trại du lịch nông nghiệp của Thái Nguyên nên thành lập trang mạng xã hội của riêng họ và hợp tác với các trang trại khác để tạo ra trải nghiệm du lịch nông nghiệp toàn diện. Trang web nên cập nhật, cung cấp thông tin về canh tác, giá nông sản, các dịch vụ và bản đồ về các điểm du lịch nông nghiệp của Thái Nguyên.

Với sự phát triển nhanh chóng của máy tính lượng tử thì thuật toán Shor có thể phá vỡ hết các lược đồ chữ ký số phổ biến hiện nay như RSA, ECDSA, EdDSA trong thời gian đa thức. Chính vì vậy, các lược đồ chữ ký số hậu lượng tử được phát triển nhằm kháng lại tấn công này. Lược đồ chữ ký số dựa trên hàm băm mật mã là một trong các lược đồ chữ ký số hậu lượng tử đang được quan tâm và có nhiều công trình công bố. Trong đó hai lược đồ chữ ký số một lần W-OTS và W-OTS+ được phát triển và là nền tảng để xây dựng các lược đồ chữ ký số hậu lượng tử tân tiến hơn sau này như XMSS hay SPHINCS+. Mục tiêu của bài báo này đi phân tích, so sánh độ an toàn và hiệu năng cài đặt thực nghiệm của hai lược đồ chữ ký số W-OTS và W-OTS+ dựa trên phương pháp nghiên cứu là tổng hợp từ các tài liệu công bố và cài đặt thực nghiệm bằng ngôn ngữ lập trình Python. Các kết luận về sự an toàn của hai lược đồ này trong bài báo được trích dẫn từ các công trình khác và cũng có kết luận là đóng góp của riêng chúng tôi.

Khử nhiễu muối tiêu là một bước tiền xử lý quan trọng trong xử lý ảnh để nâng cao chất lượng hình ảnh. Các phương pháp khử nhiễu truyền thống xem xét các điểm ảnh có giá trị bằng 0 hay giá trị cực đại là điểm ảnh nhiễu muối tiêu thực sự, tuy nhiên trong nhiều trường hợp những điểm ảnh này không phải là điểm ảnh nhiễu mà là điểm ảnh kết cấu dẫn đến kết quả khử nhiễu còn có hạn chế đặc biệt khi tỷ lệ nhiễu là cao. Nghiên cứu này sẽ khắc phục hạn chế trên, tại bước phát hiện điểm ảnh nhiễu, thuật toán sử dụng cửa sổ có kích thước thích nghi để phân biệt một điểm nhiễu ứng viên là điểm nhiễu thực sự hay là điểm ảnh kết cấu dựa trên quan sát rằng điểm ảnh nhiễu thường là điểm ảnh cô lập, ở đó giá trị điểm ảnh là thay đổi so với các giá trị điểm ảnh xung quanh. Sau đó điểm ảnh nhiễu sẽ được thay thế bởi một giá trị mới dựa trên các điểm lân cận. Phương pháp này chỉ áp dụng trên ảnh đa mức xám. Các kết quả thực nghiệm cho giá trị trung bình tỷ lệ tín hiệu trên nhiễu cực đại và độ tương tự về cấu trúc ở tất cả các cấp độ nhiễu lần lượt là 28,1631và 0,8496. Phương pháp đề xuất khử nhiễu muối tiêu là rất hiệu quả dựa trên các kết quả thực nghiệm. Các kết quả sau khi khử nhiễu cho chất lượng ảnh tốt tại tất cả cấp độ nhiễu.
NEMO TENETUR İLKESİNİN ŞAHSİ CEZASIZLIK SEBEBİ VE TANIKLIKTAN ÇEKİNME YETKİSİ İLE BAĞLANTISI: SUÇU BİLDİRMEME SUÇUNA İLİŞKİN KANUN HÜKMÜNÜN İPTALİ
Authors: BULUT Esra

Adliyeye karşı suçlara yönelik şahsi cezasızlık sebepleri, tanığın şüpheli veya sanık ile akrabalığı nedeniyle tanıklıktan çekinme yetkisi ve soruşturma veya kovuşturma konusu suçla irtibatlı tanığa yemin verilmemesi düzenlemelerinin amaçları aynıdır. Amaç, kişinin kendisini ve yakınlarını suçlayıcı beyanda bulunmaya ve bu yolda delil göstermeye zorlanamaması şeklinde ifade edilen nemo tenetur ilkesinin hayata geçirilerek insan onurunun korunmasıdır.

Anayasa Mahkemesi, nemo tenetur ilkesine aykırı olduğu gerekçesiyle suçu bildirmeme suçunu düzenleyen kanun hükmünü iptal etmiştir. Bunun üzerine kanun koyucu suçu bildirmeme suçuna yönelik şahsi cezasızlık sebebi düzenlemesi eklemiştir. Bu düzenlemede şahsi cezasızlık sebebinden yararlanabilecekler, tanıklıktan çekinebilecek kişilere atıf yapılarak belirlendiğinden Türk Ceza Kanunu’nda ve Ceza Muhakemesi Kanunu’nda düzenlenme amacı aynı olan bu iki kuruma bir bağlantı noktası sağlanmıştır.
HIRSIZLIK SUÇUNUN BİNA VEYA EKLENTİLERİ İÇİNDE MUHAFAZA ALTINA ALINMIŞ OLAN EŞYA HAKKINDA İŞLENMESİ (TCK m. 142/2-h)

Published: January 2024

TCK’nın 142/2-h hükmünde hırsızlık suçunun “bina veya eklentileri içinde muhafaza altına alınmış olan eşya hakkında” işlenmesi nitelikli unsur olarak düzenlenmiştir. Fakat Yargıtay içtihatları tetkik edildiğinde, söz konusu yasal düzenlemenin ve uygulamasının sorunlu olduğu görülmektedir. Çalışmada, tespit edilen iki sorun incelenmiştir. Bunlardan ilki, eşyanın bina içinde muhafaza altına alınmasından ne anlaşılması gerektiği; ikincisi ise, binanın konut veya işyeri vasfını taşıması halinde suçun icrasının ne zaman başladığı ve 142/4 hükmüyle de bağlantılı olarak suçlar arasındaki içtima ilişkisidir.

ON THE ORIGINS OF THE STORY OF THE SYNOD OF DALMA
Authors: Kunčer Dragana
Published: January 2024

The article presents a re-examination of the story of the Synod of Dalma, which is primarily found in the chronicle Gesta regum Sclavorum (GRS). The author argues that GRS is a medieval compilation of diverse texts that were revised and adapted to fulfill the objectives of the chronicle’s author. Through an examination of the presumed prior source of the story, or “hypotext”, the article scrutinizes its potential content, date, and purpose. This examination of the Synod of Dalma’s story allows for the re-establishment of the relationship between GRS on the one hand, and the Cyrillic-Methodian tradition, the formation of Christian Moravia, and the reign of the Great Moravian ruler Svatopluk on the other hand. The study concludes that this narrative from GRS could potentially offer valuable insights into the history of the Slavs in both the Balkans and north of the (Middle) Danube. Ultimately, a re-evaluation of the credibility of the entire text of GRS is suggested

The paper aims to outline one stage of the Hungarian-Ottoman battles in the area of Posavlje, in which Serbian warriors played their role. In addition, our intention was to make the reconstruction as detailed as possible, using the most important Western and Hungarian diplomatic and narrative sources along with relevant literature in Serbian and Hungarian languages. Among the sources, we placed a particular emphasis on the epic about the siege of the city in the Hungarian language, which is also one of the oldest works of this kind among the Hungarians and has so far not received adequate attention in Serbian historiography.
