Perjanjian baku diperlukan guna menunjang kegiatan perdagangan barang dan/atau jasa seiring dengan berkembang pesatnya inovasi teknologi, seperti halnya penggunaan perjanjian baku oleh perusahaan penyedia jasa transportasi online terhadap para konsumen yang menggunakan jasanya, dimana permasalahan hukum terjadi saat konsumen yang menggunakan jasa transportasi online diwajibkan menyetujui syarat dan ketentuan pada saat proses pemasangan aplikasi transportasi online agar aplikasi dapat digunakan tanpa terlebih dahulu membaca isi dari syarat dan ketentuan tersebut, sehingga luput dari pengawasan dan pengetahuan konsumen bahwa pelaku usaha dapat saja mencantumkan klausula baku yang mengandung klausula eksonerasi yang dilarang UUPK. Metode penelitian yang digunakan pada penelitian ini adalah penelitian hukum yuridis-normatif. Hasil penelitian menunjukan bahwa pertama, klausula eksonerasi dilarang untuk dicantumkan pada perjanjian baku berdasarkan Pasal 18 ayat (1) UUPK, yang mana apabila itu dicantumkan pada perjanjian baku mengakibatkan klausula tersebut dinyatakan batal demi hukum dan harus diajukan pembatalannya kepada pengadilan yang berwenang, dan kedua berdasarkan analisis kasus, bahwa klausula baku yang menentukan forum penyelesaian sengketa secara sepihak pada dasarnya tidak bertentangan dengan UUPK karena tidak dilarang, namun untuk klausula baku yang mewajibkan konsumen untuk tunduk kepada peraturan yang ditetapkan oleh pelaku usaha secara sepihak berpotensi mengandung klausula eksonerasi sehingga dilarang dicantumkan pada perjanjian baku.

Lite-UNet: A Lightweight and Efcient Network for Cell Localization
Authors: Li Bo
Published: September 2023

Cell localization constitutes a fundamental research domain within the realm of pathology image analysis, with its core objective being the precise identification of cell spatial coordinates. The task has always involved the challenge of large color variations among cells, uneven distribution, and overlapping borders. Furthermore, in realistic cell localization scenarios, the existing state-of-the-art methods suffer from high computational costs and slow inference times, which severely reduce the efficiency of computer-assisted. To tackle the above issues, a lightweight and efficient cell localization model named Lite-UNet is proposed. Specifically, the Lite-UNet encompasses three pivotal modules. Firstly, we introduce a gradient aggregation module grounded in difference convolution. This module effectively mitigates the challenge posed by extensive color variations among cells by adeptly leveraging gradient information. Secondly, we propose an efficient plug-and-play graph correlation attention module, which optimizes the feature representation capabilities by encoding higher-order feature associations. Finally, we design a lightweight Ghost\_CBAM module that alleviates the difficulty of uneven cell distribution while forming the base module of the Lite-UNet. Extensive experiments show that our Lite-UNet is capable of locating cells in images quickly and accurately, thus further improving the efficiency of computer-assisted medicine.

Accelerated Fiducial Tag Detection Using Efficient Search Algorithm with Trajectory Forecasting
Authors: Saraf Rushil , Smoragiewicz Tony
Published: September 2023

Fiducial tags have attracted increased attention and use in the robotics community due to their relative ease of detection and pose estimation. Previous methods to detect these tags search the image pixel spaces in their entirety. With the advent of higher resolution video such as 4K and increased camera frame rate, however, it has become increasingly challenging to obtain real time tag detection, especially using lower-end computing devices. 

We present a novel algorithm that accelerates the detection speed of these fiducial tags by forecasting the future trajectory of the camera, devising a prediction for the upcoming tag location in the camera frame, and significantly reducing the image search space corresponding to the prediction. Based on the data from several test trials, we tuned the algorithm parameters and compared it to the conventional full search method in multiple real-world test experiments using AprilTags. In addition to the quantitative results, we present a qualitative analysis on the optimal application scenarios for our new algorithm. Our method has demonstrated between a three to four times increase in detection speed and is robust enough to handle intermittent tag occlusion.

Authors: SUTHAR BHIVRAJ
Published: September 2023

Supernumerary Robotic Limbs (SRLs) have become an effective method for assisting post-stroke patients in their daily life activities. However, conventional SRLs are constrained by functionality, wearability, and portability limitations, which are attributed to the presence of bulky robot actuators, gears, complex design, and high power consumption. This paper presents twisted string actuated (TSAs) flexure robot joints (FRJs) for a supernumerary robotic arm (SRA). This design aims for a compact, lightweight, energy-efficient, affordable, wearable, and portable SRL. The Twisted string actuation replaces the bulky actuator and gearbox in the robot joint. The FRJ joint design and modelling is proposed for the TSA-actuated Flexure Robot Joint (FRJ) and verified through experimental validation. A prototype of the 3 Degrees of Freedom SRL was developed, weighing 2.5 kg and possessing a payload capacity of 0.15 kg. The TSA-driven FRJ can produce 3 Nm joint torque at the cost of 32.5 mNm maximum motor torque, and the full SRL’s power consumption is 40 watts. In addition, a demonstration of bimanual tasks is presented using the proposed SRL to check its feasibility. Furthermore, the proposed SRL has merits compared with the existing SRLs in the literature.
Collatz Conjecture Proof for Special Integer Subsets and a Unified Criterion for Twin Prime Identification
Authors: Zaman Budee U
Published: September 2023

 This paper presents a proof of the Collatz conjecture for a specific subset of positive integers, those formed by multiplying a prime number ”p” greater than three with an odd integer ”u” derived using Fermat’s little theorem. Additionally, we introduce a novel screening criterion for identifying candidate twin primes, extending our previous work linking twin primes (p and p+2) with the equation 2(p−2) = pu+v, where unique solutions for u and v are required. This unified criterion offers a promising approach to twin prime identification within a wider range of integers, further advancing research in this mathematical domain

Authors: Misra Utkarsh , Sahu Vikas , Das Amit Kumar , Ajimsha RS , Misra Pankaj
Published: September 2023

In this work we investigate the conductance quantization (QC or CQ) phenomenon in the Cu/Ta2O5/Pt resistive random access memory (RRAM) devices. The Ta2O5 film was deposited on Pt-Si substrate using RF magnetron sputtering, followed by patterning of Cu top electrodes. The devices demonstrate robust bipolar resistive switching behavior, with low set and reset voltages (< 1V), and high resistance contrast (~103 ), owing to the electrochemical metallization mechanism. Quantized conduction was observed during the reset operation with well-defined conduction steps. Conductance (G) histograms revealed Gaussian distribution of G/G0 around the integral and half-integral values, where G0 is the fundamental unit of conductance (77.6 μS). The maximum conductance state observed was 310G0. Moreover, the currentvoltage curves of QC reset cycles clearly revealed that multiple conduction states appear at the same current value which opens potential avenues for developing multi-state memory devices based on QC states. The findings in this work contribute to the understanding of quantized conduction in RRAM devices for non-conventional computing applications such as in-memory and neuromorphic computation.

Authors: Sheikh Shahin , Kishk Ahmed , Denidni Tayeb A.
Published: September 2023

 A novel method is proposed for spectrally  shaping the beamforming weights quantization error at the  sub-array layer where the in-band distortion intends to  move into a position where the sub-array factor has high  attenuation. To do that, the sub-array factor or the  composite sub-array factor is tiled by the periodicity of the  ultimate-layer array factor. Then, the digital filter layout is  designed based on the superposition of all tiles intersecting  with the visible region of the overall array factor (O-AF),  and the O-AF is spectrally shaped to minimize the number  of bits quantifying the beamforming weights. The method is  investigated for analog, digital, and hybrid array  beamforming with multi-layer overlapped sub-array  systems of different sizes and shapes. Its performance is  promising and potent in alleviating the overall array factor  distortion in all cases.

 As spinal cord injury (SCI) disrupts the communication between neural circuitry, electrical stimulation of the spinal cord may improve the rewiring and recovery of the affected pathways. Recent advancements in transcutaneous spinal cord stimulation (tSCS) have shown the potential for neurological enhancements in individuals living with SCI. In this study, we introduce the Reynolds Innovative Spinal Electrical Stimulation (RISES) technology, a person-tailored, task-specific stimulation system with real-time optimization capabilities enabled by its multi-data acquisition and closed-loop capabilities. We piloted the safety and feasibility of the RISES system by implementing the developed technology as part of a clinical trial intervention aimed to apply closed-loop tSCS during activity-based training. The successful use of RISES confirmed its safe and feasible closed-loop tSCS methods, resulting in measurable immediate improvements in proximal muscle activation and with no adverse physiological effects being observed in the preliminary data.

Published: September 2023

Drowsiness is the leading cause of many fatal accidents and a substantial financial burden for the economy. Efforts have been made to develop techniques to prevent major accidents while remaining practical for everyday use. The most successful approach discovered thus far involves utilizing physiological techniques that rely on EEG signals. Despite their promising performance, the signal collection process has made them unsuitable for practical implementations. However, the emergence of low-cost commercial EEG headsets has enabled tackling this issue. Our study aimed to assess the effectiveness of machine learning models in identifying drowsiness stages using minimal EEG channels. The study was conducted with fifty sleep-deprived participants driving in a simulator. Based on the Observer Rated Drowsiness method, we divided the stages of drowsiness into three categories: alert, drowsy, and sleepy. Various features were extracted from the EEG signals in time, frequency, and time-frequency domains. Three models were trained in each domain using k-nearest neighbors and ensemble bagged tree classifiers. A majority vote among the three models determined data labels, trained using different combinations of channel data features. Three training strategies were utilized: 1) single channel, 2) temporal channels, frontal channels, left-side channels, and right-side channels separately, and 3) all channels. The results of 10-fold cross-validation showed that the frequency features of temporal channels had the highest accuracy. The best results for nearest neighbors were 97.1% (alert-sleepy), 96.6% (drowsy-sleepy), and 96.7% (alert-drowsy). The highest accuracy of ensemble bagged trees was 100% for all three models.

Enhancing Cybersecurity for Industrial Control Systems: Innovations in Protecting PLC-dependent Industrial Infrastructures
Authors: Huang Peng-Hao , kim Jaewon , Kumar P.R. , Rajendran Jeyavijayan , Enjeti Prasad
Published: September 2023

A robust approach for cyber-security of industrial control systems (ICSs) that utilize programmable logic controllers (PLCs) to control critical industrial processes is demonstrated in this paper. For example, industrial water/chemical tank-based system, the liquid level sensor measurement output data may be compromised or manipulated by attackers, this can cause tank overflow, unregulated, or even malfunction. We proposed a general-purpose method called Dynamic Watermarking (DW) to secure ICSs. The basic idea of DW is that it adds a private random signal watermark on the control signal from the controller, then this watermark signal propagates through the plant and adequately converted then comes back to the attack detector. The attack detector at the actuator side can detect any malicious activity in the system in real time. The proposed method is experimentally tested and validated with several cyber?attack scenarios on a laboratory scale water tank level control system controlled by an Allen-Bradley Micro820 PLC. 
Transient Instability of Synchronous Condenser Co-located with Voltage Source Converters under Non-Metallic Faults
Authors: liu xinyu , Xin Huanhai , Shang Yongpeng , Zheng Di
Published: September 2023

Synchronous Condensers (SynCons) are widely used in the voltage source converter (VSC) integrated weak grid for voltage support and oscillation suppression. Whereas recent research suggests that the SynCon may accelerate and lose transient rotor angle stability due to the excessive active power injected by nearby VSCs during metallic faults. However, the transient stability of the SynCon cannot be guaranteed even if it decelerates during non-metallic faults. To reveal this phenomenon, the transient stability of SynCon during non-metallic faults is investigated in this paper. After deriving power-angle characteristics in different operating conditions, a novel transient instability mechanism is discovered, and the effect of the system parameters is analyzed based on the Equal Area Criterion (EAC). It reveals that inertia, excitation, VSC size, and voltage support during FRT all contribute to such transient instability. To mitigate unbalanced active power during faults and improve transient stability, an adaptive fault ride-through (FRT) strategy is proposed. The electromagnetic transient (EMT) simulations based on the PSCAD/EMTDC are carried out to validate the effectiveness of the theoretical analysis and the proposed adaptive control strategy.

Published: September 2023

Gallium Nitride (GaN) transistors are gaining popularity in industrial and automotive applications due to their ability to achieve high power density and higher efficiency. However, their reliability and robustness still pose limitations to their widespread adoption. Short-Circuit (SC) robustness has been widely studied in literature by means of experimental characterizations. However, less attention has been drawn to the simulation of GaN HEMTs operating in SC conditions due to the absence of accurate models that can fully describe the main phenomena impacting the SC behavior of a GaN device: such as drain current collapse and gate-leakage current increasing. In this context, this work proposes a behavioral model for the 650-V/60-A GaN HEMT, which includes both drain and gate current.The obtained drain and gate current equations were implemented and integrated into the manufacturer model of the device in the simulation environment. The proposed behavioral model is validated experimentally by means of LTSpice simulations and experimental SC results on a half-bridge hardware prototype composed of two GaN devices at different DC-link voltages. The main outcomes demonstrate a valuable accuracy improvement in comparison with the manufacturer model.

Published: September 2023

TinyRCE is a hyperspherical classifier aimed at Continual Learning On-Tiny-Devices, a challenging task in which a Machine Learning model is required to learn from continuous streams of data while being directly installed on a (tiny) device with limited computational resources. The classifier has so far been applied to several use cases, including Human Activity Recognition, Ball Bearing Anomaly Classification, Keyword Spotting and Image Classification. The proposed work in this paper focuses on the reproducibility of TinyRCE’s experimental results already published on other papers. This to prove that all the published results are quantitatively reproducible. All the experiments have been executed on two independent computing machines to profile the impact on accuracy of the computations. As the outcomes are matching, the experimental reproducibility of TinyRCE’s accuracy over all the use cases has been positively verified.
Error Detection Schemes for τ NAF Conversion within Koblitz Curves Benchmarked on Various ARM Processors
Authors: ahmadi kasra , aghapour saeed , Mozaffari Kermani Mehran , Azarderakhsh Reza
Published: September 2023

Elliptic curves cryptography, the most widely-deployed pre-quantum public key cryptography, can be implemented efficiently with Koblitz curves. The reason for these realizations is that in such efficient architectures, through using Frobenius endomorphism, the high cost of doubling can be ameliorated by simple shifting. However, in order to use this property, scalars should be represented by a τ-expansion. Such curves require integer to τ-NAF conversion, which is a prominent factor in Koblitz curves cryptography. Nevertheless, natural and malicious faults, can threaten the reliability of such constructions. In cryptosystems, verifying the correctness of the underlying computation implemented in hardware and software platforms is extremely important to detect permanent and transient errors. In this paper, for the first time to the best of our knowledge, we investigate fault detection schemes in single and double τ-NAF (nonadjacent form) conversion algorithms. To this end, we propose refined algorithms and implementation to resist both permanent and transient error occurrence using a number of fault models to make sure the performed assessments reflect the results accurately. Additionally, we simulate the proposed algorithms in Python environment with single, random, and burst fault models resulting in very high error coverage. Finally, we implement our scheme on ARMv7 and ARMv8 platforms to show the overhead of our implementation. We achieved less than 17% clock cycle overhead on Cortex-M4 and about 25% on Cortex-A72 processors. Our proposed scheme code size overhead was less than 6%. The proposed approaches make the implementations of Koblitz curves τ-NAF conversion more reliable with acceptable overheads.

Published: September 2023

Rationale. The low efficacy of azole antimycotics in treatment of Candida infections, especially in HIV-infected patients, is often associated with overexpression of the ERG11 gene in Candida spp., which results in increased production of ergosterol the target of the above antimycotic drugs. Researchers have found ERG11 gene mutations that can modify its overexpression effects by increasing or decreasing it. However, the findings reported by different laboratories and countries are highly contradictory.
The purpose of the study is to explore the spectrum and functional properties of ERG11 gene mutations in fluconazole-resistant Candida albicans strains isolated from HIV-infected patients.
Materials and methods. The study was performed using 10 C. albicans strains inherently resistant to fluconazole and voriconazole and isolated from the oropharynx of HIV-infected patients; the strains were provided from the collection of the Gabrichevsky Moscow Research Institute of Epidemiology and Microbiology. The strains were assessed by their sensitivity to antimycotic agents: anidulafungin, micafungin, caspofungin, posaconazole, voriconazole, itraconazole, fluconazole, amphotericin B, 5-flucytosine. Expression levels of the ERG11 gene were measured by quantitative PCR. ERG11 gene mutations were identified by Sanger sequencing.
Results. Five mutations (E266D, G464S, I471L, D116E, and V488I) were detected in the ERG11 gene in seven C. albicans strains; six strains carried non-associated co-occurring mutations. Increased expression of the ERG11 gene was found in six C. albicans strains. The V488I mutation demonstrated a strong negative association with the increased expression of the ERG11 gene (r = 0.845; p 0.05). The minimum inhibitory concentration (MIC) in strains carrying mutations was a hundred times as low (p 0.05) as MIC in strains without mutations. In mutation carriers, posaconazole and itraconazole MICs were on average 16.5 times as low as MICs of voriconazole and fluconazole (p 0.001). The presence of mutations in the ERG11 gene had almost no effect on MICs of the tested antimycotics of the echinocandin, polyene, and pyrimidine groups.
Conclusion. Multiple mutations were detected in the ERG11 gene in most of the C. albicans strains isolated from HIV-infected patients and resistant to fluconazole and voriconazole. Except for the V488I mutation, the detected mutations were not associated with the overexpression of the ERG11 gene and decreased the effects of overexpression of the ERG11 gene by up to 100 times, though they did not eliminate the inherent resistance to triazole antimycotics.

Introduction. Hepatitis C is a liver disease with high chronicity, the cause of cirrhosis and hepatocarcinoma. The main obstacle to controlling hepatitis C is the lack of vaccines.
The aim of the work was to compare the immunogenic activity of nonstructural recombinant proteins NS3, NS4 and NS5B of hepatitis C virus (HCV) as components of a subunit candidate vaccine and to analyze the adjuvant properties of two available commercial drugs, polymuramil and pyrogenalum.
Materials and methods. BALB/c, DBA/2J and C57BL/6 mice were immunized with nonstructural proteins without adjuvants or with polymuramyl (NOD1 and NOD2 agonist) and pyrogenalum (TLR-4 agonist). The activity of antibodies was determined in ELISA, the cellular response by antigen-specific lymphocyte proliferation and by production of IFN- in vitro.
Results. Recombinant proteins showed different immunogenicity. NS4 induced antibodies more efficiently than NS3 and NS5B. Significant differences were found in the immune response of three inbred lines mice: the level of IFN- in BALB/c and DBA/2J mice induced by NS5B protein was 30 times higher than in C57Bl/6 mice. In contrast, the induction of antibodies in BALB/c mice was lower than in C57Bl/6 and DBA/2J. Polymuramil did not increase the humoral response to NS5B and enhanced the cellular response only in C57BL/6 mice. The combined use of polymuramil with pyrogenalum significantly increased both the humoral and cellular response of mice to all recombinant HCV proteins.
Conclusion. Different immunogenic properties and different functions of recombinant non-structural HCV proteins indicate the feasibility of their combined inclusion in subunit vaccines. It was established for the first time that immunization with HCV proteins with a complex adjuvant (polymuramyl + pyrogenalum) has a synergistic effect, significantly exceeding the effect of each of them separately.

The titer of the measles virus in the PRM for each determination of the specific activity of the measles virus in vaccines in the Scientific Centre for Expert Evaluation of Medicinal Products in 20212022, as well as according to the summary production protocols, was within the boundaries of the certified value (4.63 0.5) lgTCD50/0.5 ml, and the test results met the acceptance criteria in accordance with the requirements of regulatory documentation. During the observation period, the average value of the PRM titer (4.61 lgTCD50/0.5 ml) practically did not differ compared to the average value of the certified characteristics of the PRM, the standard deviation of the mean value of the measles virus titer in the PRM did not exceed 0.15 lgTCD50, which indicated the stability of the analytical work at the enterprise and in IC.
Conclusion. The data obtained indicate the stable activity of PRM, the correctness of the determination of the measles virus titer in the vaccination dose of the vaccine, and the validity of the method for monitoring the specific activity of the measles virus in vaccines.
Martin Heinrich Klaproth (1743-1817), a Great, Somewhat Forgotten, Chemist
Authors: Maar Juergen Heinrich
Published: September 2023

For various reasons, some of them linked to the evolution of the historiography of Chemistry, many recognized and important chemists in their time – and in ours, because of the legacy they left – are relegated to some degree of oblivion. One of these chemists, dead just over 200 years ago, is Martin Heinrich Klaproth (1743-1817), a key figure in the transition from phlogiston theory to Lavoisier’s new chemistry and one of the creators of modern analytical chemistry, an empiricist who discovered many elements and polymorphism, author of remarkable chemical and mineralogical analyses and creator of archaeometry. This article presents the life, training and scientific production of a great, but less remembered, chemist, crossing the frontiers of Chemistry in many cases.

The medium voltage network of bacan feeders was an air line power network and had a very high potential to experience disruptions impacted on customer outages. The bacan feeder network was divided into sections uisng breaker equipment (Recloser/LSBM) in order to narrow down the area of blackout when a disturbance occurs. The work function of the breaker equipment was not yet optimal, so it can have an impact on the length of time the customer goes out when there was a network disturbance. From the simulation of the existing feeder conditions, the ENS (Energy Not Supplied) results were really high and the duration of the shutdown was every long so we optimize the breaker equipment (LBSM) by resetting the sectionalizer and telesignaling SCADA (Supervisory Control And Data Acquisition) and RTU (Remote Terminal Unit) on LBSM that has not been intergrated with SCADA. Based on the results of the analysis, evaluation and simulation, after the optimization of the SCADA-based sectionalizer function had been applied to the LBSM equipment, the ENS value and the feeder shutdown duration function due to the disturbance of the bacan feeder network could be significantly reduced

Authors: Badin Pairins , Hamid Hashima
Published: September 2023

Co-curricular activities encompassing uniform units, clubs, and associations are compulsory courses in all educational institutions in Malaysia. The implementation of co-curricular activities requires neat preparation in order to reduce exposure to the risk of loss, injury, and accidents during the activities. Therefore, this study aimed to produce an instrument for effective co-curricular activity risk management (also known as (CoARM) to guide administrators, lecturers, and students, in conducting safe co-curricular activities, especially at Malaysian teacher education institute (TEIM). This study used the Fuzzy-Delphi method involving 30 experts in the field of co-curriculum from public universities and TEIM. The questionnaire was constructed based on the analysis of field expert interviews and a literature review. It was then sent for expert agreement on the elements, sub-elements, and content of CoARM at TEIM. The findings distinguish three (3) elements and fifteen (15) sub-elements of CoARM when planning and implementing co-curricular activities. The first element was the human element involving trainers, participants, support staff, service providers, and external agencies. The second element, the equipment element, involved anchorage, accommodation, facilities for special activity equipment, and safety equipment. The third element was the environment element with the sub-elements of weather, location, activity routes, security threats, and rescue routes. The CoARM instrument is expected to provide new knowledge as well as to serve as a guide in the field to increase the public’s confidence in organising co-curricular activities at Malaysian educational institutions and as a reference source in the future construction of CoARM modules.
Digital Verses Versus Inked Poetry: Exploring Readers’ Response to AI-Generated and Human-Authored Sonnets
Authors: Rahmeh Hassan
Published: September 2023

This research contrasts the reactions of postgraduate English Literature students from the Lebanese University to a pair of sonnets. It particularly examines Shakespeare's "Sonnet 18" alongside a sonnet crafted by ChatGPT, both echoing the theme of timeless beauty. This research uses quantitative methods to assess participants' appreciation of these two sonnets, the felt emotional depth, and the perceived language complexity. Additionally, the study explores students' viewpoints on AI-generated poetry and identifies any perceived limitations in the AI sonnet compared to the human-authored one. The findings revealed that students favored Shakespeare's “Sonnet 18” over the AI-generated version due to its complex language and greater emotional resonance. Seeking to offer meaningful insights, this study delves into how the academic literary community perceives and interprets AI-generated literature. It further adds to the current discussion and debate about the role of AI in augmenting creative writing and underscores areas of potential improvement in upcoming AI literary projects.
صور من التكرار في قصيدة زجل الأثير للشاعر موسى كليم القالي: دراسة أدبية

Published: September 2023

يُعد التكرار ظاهرة فنيّة عرفها الشعر العربي منذ القديم، وأقبل على توظيفها كبار الشعراء، للتعبير عن أفكارهم وتطلّعاتهم، فالتكرار يحمل في أثنائه دلالات نفسية وانفعالية مختلفة تفرضها طبيعة السياق، ويُعد وسيلة من وسائل تشكيل الموسيقى الداخلية، وظاهرة من ظواهر المهمّة والمثيرة في قصيدة الشاعر موسى كليم القالي. والتكرار في شعره أضفى جمالا فنياً وثراءً دلالياً، وإيقاعاً ترنمياً، وقد أخرجه من السطيحة إلى الظرافة والبراعة الفنيّة، وأسهم في خلق أجواء موسيقة تدفع القارئ إلى التلذّذ والتمتّع بالنص وتبعده عن التعب والملل والرتابة. واستخدم الشاعر ظاهرة التكرار بأنواعها الثلاثة، وهي الحرف (الصوت)، والكلمة، والعبارة، وقد تفنّن الشاعر في استخدام التكرار في تجربته الشعرية التي بصددها.

Background and Objectives: Endoscopic myotomy is a recent technique that did spread quickly across high-income countries. The aim of this study is to report the experience of our department regarding the practice of POEM. Study design: It is a retrospective study including 13 patients with achalasia treated by POEM at the Department of Digestive Functional Explorations (EFD-HGE) of University Hospital Center Ibn Sina of Rabat, between January 2017 and June 2023. There was a break during the COVID19 pandemic and the endoscopic activity was stopped for a while. Results: The median age was 40, 46. Women were more affected than men: 69% and 31% respectively. Only 15% of cases had previous treatment (pneumatic dilation/surgical myotomy). The clinical success rate reached 84.6%. The mean of Eckardt scores decreased from 8 at baseline to 3 at 2 months. The IRP’s mean decreased from 23.9 mmHg to 15.6 mmHg after the gesture. The post-POEM reflux rate was less than 16%, but the rate of serious adverse events was relatively high. Conclusions: POEM is an effective procedure to treat achalasia with a low morbidity, provided that it is carried out in an expert center with suitable and good quality material.

Covid-19 has rapidly became a major public health crisis. Several public health and containment measures were deployed to contain this epidemy; however, a return to a normal life could only be expected after the generalization of anti-Covid 19 vaccination, allowing a global collective immunity. The success of this campaign depends essentially on the acceptance of the new Covid-19 vaccines. We conducted a descriptive and analytical observational cross-sectional study to evaluate the acceptability of Covid-19 vaccines, among resident and intern doctors at the Mohammed VI University Hospital in Marrakech, to determine the factors associated with vaccine acceptance, and the reasons for hesitation or nonacceptance of vaccination. Out of 145 participants (59.1% female, mean age 26.6 years), 89.7% received the vaccine at least partially. 49% of our population did not delay their vaccination and intended to complete it, so we considered them accepting. However, 40.7% were considered hesitant because of delayed or abandoned Covid-19 vaccination. People living alone and resident physicians in medical or biological specialties were the most likely to accept vaccination. Factors influencing refusal or hesitation included: speed of vaccine development, fear of adverse effects, lack of information on vaccine efficacy, acquisition of natural immunity following previous infection with Covid-19, lack of confidence in the pharmaceutical industry. Doctors' general attitudes towards COVID-19 vaccination, in our study, are positive, but specific concerns about the COVID-19 vaccine are widespread. Addressing barriers to vaccination in these groups will be essential to avoid exacerbating the health inequalities highlighted by this pandemic.
