Penetrating brain injuries due to sharp knife are low velocity trauma but need urgent surgical intervention. We discuss a 28-year COVID positive male with left supra orbital penetrating brain injury with a sharp knife. Radiology showed the object entered through the left frontal bone near the key burr point. Reconstructed CT images showed the entry point close to the sylvian fissure and the trajectory was away from it. Craniotomy was done leaving a rim of bone around the knife, dura opened, sylvian veins were seen and the knife was gently pulled out without any additional injury. The patient recovered without any complication. Proper preoperative evaluation and surgical planning is essential in extraction of sharp objects in cases of penetrating brain injuries.

New concepts of hospitalization of hanseniasis patients and their practical application in Sao Paulo, Brazil
Authors: OAVALCANTI A. P. , FONTANA L. , ROTBERG A.
Published: December 2023

Five large specialized "asilo-colônias" were founded in the early thirties in São Paulo with two main objectives —asylum for the physically and/or socially handicapped "lepers", and compulsory isolation for infectious patients. The former degenerated by abuse and institutionalism; the second failed in its purpose of control, and kept the social atmosphere tense. With their resources jammed, these establishments were not able to offer a reasonable degree of comfort and medico-social assistance to their increasing number of Inmates. About 1/3 of the 5.000 hanseniasis patients have been transferred to dispensaries In 1967, and one of the "colonies" was converted into a psychiatric institution. Applications for asylum care are now carefully scrutinized by social workers, and prophylactic isolation is infrequent. Physical rehabilitation, intercurrent illness and scientific research are now the chief reasons for hospitalization, and facilities for such purposes are increasing. The establishments were renamed "Hospitals de Dermatologia Sanitária", after having been dissociated from the extinct "Leprosy Department" and integrated with other public health hospitals. They are frequented by medical students in their curricular activities, and are often the site of dermatological meetings and extracurricular courses. In one of the hospitals, an infirmary is receiving various dermatological cases. The image of the old dreadful "asilo-colônias" Is fading slowly but steadily.

Published: December 2023

Um paciente, portador de infecção hansênica há 20 anos, e considerado como virchowiano inativado, apresentou nos últimos 4 anos de vida, dois surtos de reação de pseudo-exacerbação (reação reversa), o último deles coincidindo com internação onde foi diagnosticado um carcinoma bronquiolar dos pulmões, cujo agravamento ocasionou o óbito. Discutem-se as dificuldades do diagnóstico clínico diferencial deste tipo de carcinoma pulmonar com outras patologias com características clínicas e evolutivas semelhantes, bem como a dificuldade de se chegar a este diagnóstico apenas pela análise de uma biopsia pulmonar. Em relação às reações de pseudo-exacerbação, duas interpretações são postas em confronto, e é salientada a hipótese destas reações se desenvolverem como resposta a surtos de proliferação bacilar que podem ocorrer em pacientes dimorfos em qualquer fase da evolução da infecção, devido a tratamento inadequado ou resistência medicamentosa. Também analisa-se a eventual relação do último surto reacional com alterações da imunidade celular secundárias ao desenvolvimento da neoplasia pulmonar.

This study utilized data spanning from 1990 to 2022 to investigate the impact of government expenditure on agricultural output in Nigeria. Employing the Autoregressive Distributive Lag (ARDL) methods, the study revealed a negative relationship between both government credit to agriculture and government expenditure on agriculture with agricultural output. The paper further recommended that Effective management of allocated resources in the agricultural sector is crucial, as merely increasing the budgetary allocation to the sector does not guarantee improved performance. To enhance the sector's functioning, consistent implementation of government policies and programs is essential also Many farmers are hesitant to seek loans from financial institutions due to concerns about collateral security and high interest rates. Therefore, the government should enact legislation that fosters a favorable lending environment for agricultural investments. Additionally, significant funding should be directed towards banks specializing in agriculture, such as Agricultural Development Banks (ADBs) and similar institutions, to support farming operations.

Factors Affecting the Cost Management of Iraqi Construction Firms
Authors: Alani Semaa Hazim Najim , Mahmoud Awss Hatim
Published: December 2023

Cost management refers to the procedures that must be followed to ensure that the project is accomplished on time and on budget. The goal of this study is to identify the main factors that affect cost compliance and to assess how relevant these factors are from the perspectives of clients, contractors, and consultants in construction firms in Iraq. For the purpose of this study, 100 structured questionnaires were distributed to clients, contractors, and consultants on building sites throughout the study area by using the survey approach. The Relative Importance Index (RII) technique was used for the analysis. It has been determined that the factors potentially affecting cost management in construction firms should be taken into consideration during the planning, design, tendering, and construction stages to accomplish the project within the specified time and cost. Twenty factors that affected the performance of construction firms in Iraq were identified. The results revealed the most affecting factor was poor management/poor coordination between the contracting company and the authorities involved, followed by the nationality of workers, structural materials damaged during storage, the absence of places designated for storing materials, lack of personnel specializing in devices and equipment, changing labor and material prices as a result of political changes, lack of technical staff, length of the project period, mismatch designs with execution works in site, and changes in orders. The study concludes by stating that there is not an efficient procedure in Iraq to control cost management.

Authors: Bukke Balaji Naik , Manjunathachari Kamsali , Sabbavarapu Srinivas
Published: December 2023

In the modern era of signal processing, digital filters play an important role in real-time applications such as communication, consumer electronics, digital signal processing, audio, etc. In digital filter design, Finite Impulse Response (FIR) filters are highly preferable due to their linear phase and inherent stability. These filters benefit from being time-invariant and simple to implement with minimal computational requirements. Therefore, the hardware security of FIR filters is essential for good performance and reliable results. On the other hand, there is the possibility of hardware threats, such as tampering, reverse engineering, hardware Trojans, etc., as the design of an FIR filter involves many stages. Such hardware attacks on FIR filters can cause several problems, including performance degradation, leakage of confidential information, lack of stability, etc. This study presents the design and implementation of a Trojan-aware FIR filter using Physical Unclonable Functions (PUFs). The key feature of PUFs is that they generate a unique and unpredictable response for each given challenge. In the proposed design, PUFs were used to generate the FIR filter coefficients that are unique and unpredictable by attackers/trojans to improve security. The security of FIR with PUF was tested using ML-based challenges, and the results showed approximately 30% more reliability and consistency compared to the FIR without PUFs.

Authors: Sazaly Alysa Nur , Mohd Ariff Mohd Farid , Razali Ahmad Firdaus
Published: December 2023

The application of micro Unmanned Aerial Vehicles (UAVs) in photogrammetry, particularly within the realm of forensic investigation represents a relatively novel approach and has gained increased attention. By measuring the distances and positions of the scene’s components, it is feasible to document and visualize the scene using the photographs that were taken for the purpose of assisting investigators. Capturing accurate crime scene data within a short time frame is always a challenge. Conventionally, photographs were used to document the scene, but the technical qualities of the photographs depended on the skill of the present forensic personnel. The use of 3-Dimensional (3D) photogrammetry enables the production of highly realistic and detailed 3D documentation of a given scene. As this technique involves capturing a series of photographs, it can be a time-consuming process. Therefore, this study aims to explore an alternative approach that enables the rapid acquisition of the scene while preserving the intricate details, thus ensuring efficiency without compromising the accuracy of the resulting documentation. The study employs a methodological approach wherein data are collected from a simulated crime scene situated within a confined and hard-to-reach area. The data collection is facilitated through the utilization of micro UAVs. The acquired data are then processed utilizing photogrammetry software, leading to the generation of a 3D model point cloud. The collected data will be subjected to a comparative analysis with data generated using a Terrestrial Laser Scanner (TLS) as a reference, alongside Vernier Calliper (VC) measurements. The findings indicate that the Root Mean Square Error (RMSE) of the integrated point clouds from TLS and micro UAVs compared to the conventional method is approximately ±0.217 cm. It can be deduced that the integration of data derived from micro UAVs and TLS in forensic photogrammetry within a confined crime scene is viable and yields a high-precision 3D model point cloud.
Optimizing the Effectiveness of Magnetic Lenses by utilizing the Electron Optical Design (EOD) Software
Authors: Shakor Ali Rabab , Hussein Mohammed Abdullah , Al-Salih Rafa Younus Jasim
Published: December 2023

This paper introduces a computational analysis that discusses an approach for optimal synthesis in the design of magnetic lenses, specifically focusing on the analytical method. A widely employed approach for magnetic lens design involves utilizing an analysis optimization procedure, which makes use of the finite element method and is supported by Munro programs. In this study, this approach has been employed to explore magnetic lenses using the Electron Optical Design (EOD) software. The study offers insights into the role of the air gap in magnetic lens design, highlighting its importance in optimizing objective and projector properties. The analysis reveals that variations in the air gap (S) significantly influence the performance of magnetic lenses. Decreasing the air gap when it is set to (3) leads to substantial improvements in objective optical properties and focal length. Conversely, increasing the air gap when it is set to (12) enlarges the half-width of the axial magnetic field while reducing the maximum magnetic field value. These findings underscore the importance of carefully optimizing the air gap to achieve desired lens performance. The focal length is determined using this input data and coefficients of aberration (spherical and chromatic) of the objective. The study focuses on the influence of a crucial geometric parameter, specifically the air gap (S), on both objective and projector properties. Its importance stems from its capability to pinpoint the suitable geometry for magnetic lenses, thereby facilitating their efficient application.
IoT Device Identification and Cybersecurity: Advancements, Challenges, and an LSTM-MLP Solution
Authors: Alshaya Shaya A.
Published: December 2023

Over the past few years, there has been an undeniable surge in the deployment of IoT devices. However, this rapid growth has brought new challenges in cybersecurity, as unauthorized device deployment, malicious code modification, malware deployment, and vulnerability exploitation have emerged as significant issues. As a result, there is a growing need for device identification mechanisms based on behavior monitoring. To address these challenges, Machine Learning (ML) and Deep Learning (DL) techniques have been increasingly employed due to advances in the field and improved processing capabilities. However, cyber attackers have developed adversarial attacks that focus on modifying contexts and evading ML evaluations applied to IoT device identification solutions. This article highlights the importance of addressing cybersecurity challenges in the IoT landscape and proposes a hardware behavior-based individual device identification approach using an LSTM-MLP architecture. The proposed architecture was compared to the most common ML/DL classification techniques using data collected from 45 Raspberry Pi devices running identical software and showing promising results in improving device identification. The proposed LSTM-MLP method outperformed previous solutions, achieving an average increase in F1-Score of +0.97 and a minimum TPR of 0.97 for all devices.

Authors: Hoang Anh , Nguyen Son Thanh , Pham Tuan Van , Pham Tu Minh , Trieu Linh Viet , Cao Trung Thanh
Published: December 2023

Autonomous mobile robots belong to automatically controlled objects that are designed and produced for various demands. This study aimed to develop an inexpensive platform of autonomous mobile robots that can be used for educational and research purposes in technical universities. The robot was built based on popular ultrasonic sensors to detect obstacles and a Raspberry Pi 4, which is a Linux-embedded computer. An effective obstacle avoidance algorithm for the robot was developed using a Bayesian neural network for classification. Training a Bayesian neural network does not require a validation dataset separate from the available data. In addition, the Bayesian approach can effectively handle the uncertainty of the system and result in the best generation for the network when inferring the unseen data. Training data are generated using robot-to-obstacle distances and the corresponding navigation modes. The commands to control the left and right motors of the robot are generated by the pretrained Bayesian neural network for three modes of navigation, forward, left, and right. Finally, this system can be useful as it can be conveniently integrated with advanced robot control algorithms.
A Power-Aware Method for IoT Networks with Mobile Stations and Dynamic Power Management Strategy
Authors: Saleh Ahmed M. Shamsan
Published: December 2023

The Internet of Things (IoT) plays a critical role in the digitalization of numerous industries, enabling increased automation, connectivity, and data collection in areas such as manufacturing, healthcare, transportation, and smart cities. This paper introduces a power-aware method for IoT networks using mobile stations and a dynamic power management strategy. The proposed method aims to improve power consumption and total packets received compared to the static-station balanced data traffic method. The proposed method uses a mobile station to dynamically adapt its transmission power based on the network conditions and the strength of the received signal. Furthermore, a dynamic power management strategy is employed to further decrease the power usage of the network by adjusting the power state of each station and IoT node according to its level of activity, data traffic, and communication requirements. Simulation results showed that the proposed method reduced power consumption by up to 64%, increased total packets received by 72%, and, as a result, increased network coverage and lifetime compared to the balanced data traffic method with static stations. This method can be employed in various IoT applications to improve power efficiency and increase network reliability.

Published: December 2023

Computer vision systems use corner detection to identify features in an image. In applications such as motion detection, tracking, picture registration, and object recognition, corner detection is often one of the initial steps. In this paper, a real-time image processing system based on Harris corner detection was designed and implemented using Zynq architecture and model-based design tools. The system was based on a development board containing the Zynq-7000 chip, which consists of a combination of FPGA and microprocessor, and the image taken with a high-resolution camera was processed in real-time by applying color conversion and Harris corner detection. The filter hardware designs used in the system were made using the HDL Coder tool in Matlab/Simulink without writing HDL code. The hardware that receives images from the camera was designed on a model-based basis with the Xilinx Vivado 2020. The HDL code that was implemented on the Xilinx ZedBoard using Vivado software was then validated to ensure real-time operation with the incoming video stream. The results achieved exhibited superiority compared to prior implementations in terms of area efficiency (reduced number of gates on the target FPGA) and speed performance on an identical target card. Using the rapid prototyping approach, two alternative hardware accelerator designs were created using various high-level synthesis tools. This design used less than 50% of the host FPGA's logic resources and was at least 30% faster than current implementations.

Published: December 2023

Industry 4.0 (I4.0) implementation is a hot topic among manufacturing organizations to reach smart factory status and integrate a fully connected ecosystem. Achieving such a transition presents notable challenges for Small and Medium Enterprises (SMEs) since they often face resource and skilled personnel limitations. This study developed a domain ontology to represent various stages of maturity toward I4.0 implementation. Ontology provides a tool for SMEs to self-assess in situations of machines, processes, and factories for the dimensions of control, integration, and intelligence. This study focused on the identification of classes and relationships according to I4.0 implementation situations in the context of a manufacturing setting, the reuse of ontologies related to the domain of observations to model situations, and the creation and validation of the ontology through the information obtained from the questionnaires applied to SMEs. Finally, the ontology delivers a tool to understand SMEs' current state concerning I4.0 implementation and plan based on informed decisions about the maturity state and the technology required to advance to the next stage in their manufacturing processes.

Qué podemos aprender sobre los sistemas educativos latinoamericanos a partir de las pruebas internacionales. Una breve incursión
Authors: Carnoy Martin , Khavenson Tatiana
Published: December 2023

El artículo señala que hace más de 50 años había ya preocupación por la calidad educativa, pero casi no había bases de datos para comparar sistemas nacionales y las herramientas analíticas disponibles eran poco poderosas. Analiza los puntajes que obtuvieron en las pruebas PISA 2000-2018 alumnos de Argentina, Brasil, Chile, México, Perú y Uruguay, ajustándolos para descontar la influencia de los recursos familiares, la clase social promedio de la escuela y el grado en que están inscritos los jóvenes. Los puntajes ajustados son diferentes de los “crudos”, al grado que los alumnos de México, Uruguay y tal vez Brasil resultan mejor que los de Chile. En unos países, sobre todo Perú y Uruguay, hubo mejoras significativas pero gran parte se debió al aumento en la clase social y el grado escolar alcanzado en promedio por los jóvenes, más que a mejoras en el aprendizaje. Otros análisis comparan los resultados de los estados de México, evidenciando que hubo diferencias importantes, pues en unos los estudiantes consiguieron ganancias significativas, pero en unos cuantos los puntajes bajaron. Se apunta como posible explicación las diferencias en la relación entre la autoridad estatal y el sindicato.

Many have followed him in this enterprise, but several of them tinted his psychology with ideas from other philosophers and schools, mainly Plato and Neoplatonism. Saint Thomas Aquinas stands among those who tried to avoid this. In this article we will show that not only he did not consider platonic or Neoplatonic ideas in his theory about the soul and its immortality but remained in the peripatetic realm and produced a rational, Revelation-free philosophy to argue for it based on certain passages and ideas of the De Anima. Also, we will show that Aristotle considers both a strong form of anthropologic hylomorphism and a soft one, being the latter the one used by Aquinas to structure his theory on the immortality of the soul.

Nhiễm khuẩn tiết niệu (NKTN) là một trong những bệnh nhiễm trùng do vi khuẩn phổ biến nhất mắc phải trong cộng đồng và trong bệnh viện. Khoa Ngoại Tiết niệu của bệnh viện Đại học Y Hà Nội hàng năm ước tính điều trị từ 200 đến 300 bệnh nhân NKTN cấy dương tính với vi khuẩn. Trong số đó chủ yếu là điều trị nhiễm khuẩn tiết niệu cho các bệnh nhân có chỉ định phẫu thuật. Tuy nhiên hiện chưa có báo cáo cụ thể về nhóm bệnh nhân này. Mục đích của nghiên cứu là mổ tả các đặc điểm và kết quả điều trị của các bệnh nhân nhiễm khuẩn tiết niệu trước mổ. Chúng tôi tiến hành hồi cứu mô tả 101 bệnh nhân nhập viện điều trị nhiễm khuẩn tiết niệu trước phẫu thuật có kết quả cấy nước tiểu dương tính tại bệnh viện Đại học Y Hà Nội trong thời gian từ tháng 1/2023 đến hết tháng 6/2023. Lấy mẫu thuận tiện không xác suất các bệnh nhân đủ tiêu chuẩn nghiên cứu. Tuổi trung bình của nhóm nghiên cứu là 57,87 ± 11,5 tuổi. Nữ giới nhiều hơn nam giới với tỷ lệ là 1,3. Tuổi nam giới và nữ giới không có sự khác biệt. NKTN ở bệnh nhân trước phẫu thuật chủ yếu do Escherichia coli, Pseudomonas aeruginosa gây ra và có xu hướng kháng kháng sinh đáng báo động đặc biệt ở nhóm betalactam. Nhóm aminoglycosid hiện có tỷ lệ nhạy cảm cao với cả hai chủng gây bệnh này. Số ngày điều trị nội trú trung bình 19,14 ± 13,64 ngày. Số ngày điều trị trung bình đến âm tính (bao gồm cả thời gian điều trị ngoại trú) là 22,38 ± 20,56 ngày. Thời gian điều trị nội trú kéo dài ở những bệnh nhân đa kháng hoặc toàn kháng làm tăng chi phí điều trị và tiềm ẩn nguy cơ lây nhiễm chéo. Cấy nước tiểu là xét nghiệm cần phải làm trước tất cả các phẫu thuật nội soi qua đường tiết niệu và điều trị nhiễm khuẩn tiết niệu cần phải tuân thủ theo kháng sinh đồ. Dẫn lưu thận là thủ thuật an toàn hiệu quả trong điều trị ứ mủ thận.
