Authors: Stephens Skye , McArthur Jennifer
Published: March 2024

There has been an increasing focus on the development of perpetration prevention programs designed to prevent the onset of sexual offending against children (online and offline). The present study involved a thematic analysis of 20 professional stakeholders in Nova Scotia who participated in a semi-structured interview that occurred prior to the development and implementation of a perpetration prevention program. Results highlighted that stakeholders saw value in a perpetration prevention program aimed at preventing the onset of sexual offending against children. Stakeholders noted that program content should address sexual-based concerns, focus on improving mental health and well-being, and consider the role of trauma. Stakeholders also emphasized the importance of creating a safe therapeutic environment. Several barriers were identified that focused on recruitment challenges, the role of fear and stigma, and the inclusion of diverse clients and facilitators. The importance of leveraging community organizations and supports was also highlighted. Implications of the findings are discussed in relation to perpetration prevention programming.
Food as medicine: How Eating Halal and Tayyib Contributes to a Balanced Lifestyle
Authors: Elgharbawy Amal , Azmi Nor Azrini Nadiha
Published: March 2024

Food is not just to satisfy one’s desires, but it is a way of maintaining one’s health and constantly striving to worship Allah. While the concept of eating as medicine is not new, Islam had already given guidelines on eating food through the Qur’an and Sunnah from the Prophet and the companions. In Islam, the concept of eating is based on halal and toyyib, which describes eating permissible and wholesome food according to Islamic principles. However, Muslims nowadays ignore this concept, which is taking tolls on their daily lives, making them mentally and physically unhealthy. Islam emphasises food intake because of the significant impact it may have on physical and mental well-being and the soul of an individual. The types of diet in line with Islamic teaching are also described from the practice of the Prophets. The information is collected using Scopus and Google Scholar databases in addition to the primary two sources: the Qur’an and Sunnah. The reported evidence from Qur’an and Sunnah were from trusted sources, and references are provided. The contribution of this article is to set guidelines to achieve a balanced lifestyle by consuming halal and toyyib, deriving that from prophetic practices.

Published: March 2024

The results of the study of damaged reinforced concrete beams of rectangular cross-section reinforced with fiber concrete are considered. Previously, experimental studies of beams damaged in the stretched or compressed zone, reinforced with steel-reinforced concrete, were carried out. First, the theoretical value of the load-bearing capacity of a reinforced concrete beam without damage was determined using various existing methods, and then its load-bearing capacity was determined experimentally. Based on the results, graphs of the change in deflections under the increasing load, graphs of the dependence of the relative longitudinal deformation on the load for the left and right support parts of the beam, as well as for the zone of its net bending, were constructed for each sample. At the next stage of research, the bearing capacity of two groups of reinforced beams was determined. The first group consisted of three samples with compression zone damage; the second group had two samples with damage in the stretched zone. In addition to the bearing capacity, deflections and relative longitudinal deformations are determined for each sample. Modeling and calculations were performed for five samples of reinforced beams with variation of the damage zone and its volume. In all calculations, the load was considered in the form of two concentrated forces applied symmetrically. Computer modeling and numerical analysis of damaged beams using the finite element method were performed in two computer programs ― Robot Structural Analysis and LIRA-SAPR. The maximum deflections and stresses are determined. A comparative analysis of the obtained results with the results of experimental studies was carried out. It was established that the deflections obtained as a result of calculations in the two programs are practically the same. And the tensions are somewhat different. The maximum difference in stresses is observed for the ZBP1 sample ― 11.8%. For four other samples, it is approximately the same, and on average it is 5.8%. Comparing the results of calculating the maximum stresses in LIRA-SAPR with the results of experimental studies gives a maximum discrepancy of 5.85%. And the biggest discrepancy occurs in the deflections ― here it fluctuates in the range of 19.0÷19.2%.
Numerical study of the influence of the length of a rod on its critical forces
Authors:   Odessa State Academy of Civil Engineering and Architecture, Bekshaev S.
Published: March 2024

The effect of changing the length of a longitudinally compressed rod on its critical forces is numerically investigated. The research is carried out on the example of a two-span rectilinear rod of bending stiffness constant along length, which is compressed by a constant lengthwise longitudinal force and hinged on one of the ends on an absolutely rigid support, and inside - on a support of finite stiffness. The change in the length of the rod occurs due to the movement of the end hinge support with the corresponding increase or decrease of the adjacent section of the rod without changing the position and characteristics of the remaining constraints. The dependence of the critical forces of the rod on the position of this support and, accordingly, on the length of the adjacent compressed section of the rod is investigated. Calculations are performed on the basis of the use of known exact analytical expressions of the influence functions of a rod of constant cross-section compressed by a longitudinal force constant by length. In the considered examples, qualitative signs of increase, decrease, and extremum of simple critical forces when changing the length of the rod, related to the qualitative features of the corresponding buckling forms, established earlier theoretically, were fully confirmed. In particular, exact calculations have shown that the increase or decrease of the simple critical force when the length of the fragment of the rod adjacent to the movable support is changed is determined by the type of the corresponding buckling form in the neighborhood of this support. Different possible configurations of buckling forms are considered, and the behavior of critical forces when changing the length of the rod are considered for each of the configurations. In order to verify the previously established theoretical results, which relate to the study of the behavior of not only the main critical forces, but also higher simple critical forces, which have an arbitrary number in the spectrum, the calculations are carried out in the article for the second critical forces of the rods considered in the given examples. The results of the calculations are shown in the form of graphs, which represent configurations of buckling forms of various possible types in connection with the corresponding changes in critical forces. Graphs of the dependence of the second critical force of the studied rods on their length are also given. It has been demonstrated that under certain conditions, reducing the length of the rod can lead to a reduction in its critical force.

A method of numerical modeling of acoustic fields in open areas with the possibility of parallelization of calculations is proposed. This method is part of a developed software solution that allows you to perform physical field modeling in various subject areas, being scalable in the sense of using an arbitrary set of parallel calculators. The use of existing modeling systems is associated with great difficulties in solving complex problems with a high degree of detail of the simulated object. Greater accuracy implies a high degree of discretization, a greater number of elementary model calculations performed. Parallel and distributed computing systems have a much better ratio of accuracy-approximation and time and cost costs compared to single-processor systems. Modern general purpose modeling systems use a simplified ray model of sound propagation, which neglects diffractional and interference effects, which are often critical in industrial acoustics. The article proposed a method based on the approximation of the principle of superposition of sound fields. It is accurate, while the linearity of the equations of acoustics is relevant. The basis is the Rayleigh integral and the approximation of reflective surfaces by flat point radiators. A parallel form of such a method is presented, as well as an analysis of its properties, both in sequential and parallel forms.

The experiment was conducted according to a 15-point plan. In the experiment, the following three factors of the composition of rigid pavement fiber-reinforced concrete varied: the amount of Portland cement from 290 to 350 kg/m3, the amount of basaltic fiber from 0.9 to 1.5 kg/m3, the amount of superplasticizer from 0.6 to 1% of the cement mass. A set of experimental statistical models was obtained. They describe the influence of factors on compressive strength, flexural strength, frost resistance, abrasion resistance and cost of fiber-reinforced concrete. The selection of optimal compositions of fiber-reinforced concrete rigid pavement for the roads of II-III and Ib categories was carried out using these models. The selection of optimal compositions of fiber-reinforced concrete was carried out graphically using square diagrams. The method of representing the factor space as 7 "square" type diagrams was used when fixing the amount of cement in the composition from 290 to 350 kg/m3 with a step of 10 kg/m3. This discretization allows for a clearer and more accurate search for optimal solutions. The levels of compressive strength, flexural strength and frost resistance were used as limitation criteria. These levels meet the requirements of DBN B.2.3-4:2015 for rigid pavement materials of the corresponding category. The concrete cost index was used as an optimization criterion. The abrasion resistance of concrete was also controlled to guarantee a correct choice. Two compositions of fiber-reinforced concrete for the roads of the II and III categories were chosen. These compositions have a compressive strength of 43 and 45 MPa, a flexural strength of 5 and 5.1 MPa, abrasion of about 0.36 g/cm2 and frost resistance of F200. Two compositions of fiber-reinforced concrete for category Ib roads were also selected. These compositions have a compressive strength of 48 and 50 MPa, a flexural strength of 5.5 MPa, abrasion of about 0.35 g/cm2 and frost resistance of F200. The compositions have chosen the lowest cost price while ensuring the strength and durability of the material. The use of this fiber-reinforced concrete makes it possible to increase the intervals between repairs during the maintenance of cement concrete roads in typical climatic conditions in Ukraine.

MATHEMATICAL MODEL FOR PREDICTING THE VALUES OF THE MAIN CHARACTERISTICS OF A TANKER’S SEAGOING CONDITION AFTER LOADING
Authors: Nazarenko V. M. , Savchuk V. D.
Published: March 2024

Transportation of oil cargoes by the world tanker fleet takes place in various climatic zones with significant fluctuations in ambient temperature. When the temperature of the oil cargo increases, its volume will increase, which may lead to increasing the risks of the cargo spilling onto the ship's deck. International conventions and codes that regulate the transportation of crude oil and petroleum products allow the use of only 98% of the cargo capacity of the tanker, the remaining 2% is called the safety factor, i.e. the margin of volume for the unforeseen expansion of the cargo when sailing in different climatic zones. From the other hand, the intensity of cargo operations during the transportation of various types of cargo, including oil cargo, has led to an increase in the role of the "human factor" in ship’s energetic system. Reducing the number of ship crews leads to the accumulation of fatigue, distraction of the attention of ship operators (masters) in the process of increasing the intensity of carrying out cargo operations on the ship. A significant share of tanker fleet accidents occurs as a result of loss of control over the volume of bulk cargo that is accepted in each tank of the vessel. The operator's lack of accurate information about the state of each tank’s filling at the current moment of time leads to the risk of overflowing of a separate tank, which, in turn, can cause the spillage of bulk cargo, for example, petroleum products on the ship's deck and on the water surface of the port's water area. The relevance of these problems determines the direction of this research. For constant dynamic monitoring of the tanker parameters’ conformity during loading operations, considering parameters that maximally satisfy the requirements of maritime safety and taking into account all restrictions, such as the maximum permissible volumes of oil cargo in tanks, the current study proposes to use a mathematical model and create a system for automatic control of tanker loading. Keywords: oil cargo, tanker, level gauges, safety factor, loading control, mathematical model.
DETERMINATION OF THE VESSEL’S POSITION COORDINATES BY THE ALTITUDE DIFFERENCE OBSERVATION
Authors: Raynov O.
Published: March 2024

Currently, in ocean navigation, one of the backup methods, and often the only one, is the astronomical method of determining the ship’s position. To jointly determine the latitude and longitude of a place from the end of the 19th century to the present day, only one navigation parameter is used - the altitude, although in nautical astronomy other navigation parameters can theoretically be used - altitude difference, sum of altitude, azimuth, azimuth difference, etc. In practice, there is no acceptable method for determining the latitude and longitude of a ship’s position from the measured altitude difference. The existing method of position lines for plotting isolines on a navigation map makes it possible to develop a method acceptable for navigation practice for determining the latitude and longitude of a vessel from the measured altitude difference. In this study, the author justifies the practical possibility of determining the coordinates of a vessel astronomically from the altitude difference, based on separate measurements of the altitude with a navigation sextant. The developed method for determining the coordinates of a ship's location from the measured altitude difference allows us to significantly increase the accuracy of determining the latitude and longitude of the ship's location by reducing the influence of random method errors caused by the geographical coordinates of the ship's location and the position of the Luminary illumination pole on the Earth's surfac e, as well as eliminating the influence of systematic altitude measurement errors. Another advantage of the method is that it is completely autonomous and makes it possible to use the sextant for measurements available on board. Keywords: celestial navigation, position measurement, astronomical ship positioning, altitude difference.
METHOD OF AUTOMATED CLASSIFICATION OF EMERGENCY SITUATIONS WITH A VESSEL IN THE SEAPORT WATERS
Authors: Khussein Yu.
Published: March 2024

The aim of the study is to develop a method that allows to improve the accuracy of classification of emergencies with a ship in the seaport area. To achieve the research objective, an improved method for automated classification of ship emergencies in the seaport area under conditions of deterministic uncertainty is proposed. The method consists of methods for formalising and processing knowledge on determining the classes of ship emergencies. The method of knowledge formalisation is based on the formation of a set of factors influencing the classification of ship emergencies in the seaport water area based on fuzzy binary relations of non-strict preference. The method of knowledge processing is based on the formation of productive rules for classifying emergencies with a ship in the seaport area according to the predicted or current values of the desired factors in a fuzzy formulation. The determination of the membership functions of several fuzzy variables to linguistic variables is based on the processing of expert data represented by a matrix of binary relations of the values of the membership function of the elements of the domain of determining linguistic variables. A comparative assessment of the classes of recognisable emergencies with a vessel in the seaport water area involves solving a multi-criteria optimisation problem using the hierarchy analysis method. As a mathematical model for determining the classes of emergency situations with a vessel in the seaport waters, the article substantiates a logical-linguistic productive hierarchical model. The process of determining the classes of emergency is described with the help of an algebraic model, which is closest to the linguistic description. In case of inexpediency of synthesis of products, it is proposed to use the method of fuzzy identification to reduce the number of product rules. The proposed method allows to improve the accuracy of classification of emergencies with a ship in the seaport area under conditions of deterministic uncertainty. Keywords: classification, maritime port, hierarchy analysis, fuzzy identification, logicallinguistic production hierarchical model, vessel, class of emergency situations, fuzzy variable, linguistic variable
AUTONOMOUS SURFACE AUXILIARY VESSELS: ADVANTAGES AND PROBLEMS
Authors: Volkov O.
Published: March 2024

With the continuous progress of modern science and technology and the increasing requirements for marine transport in various fields, the intelligence and automation of ships has become a general trend. Autonomous unmanned surface vessel (UASV) control generally includes UASV trajectory planning, path tracking control, and autonomous collision avoidance control. Due to their low cost, small size, fast action, reconnaissance capabilities and other advantages, BPNS play a very important role in everyday life, emergency response and scientific research. UASV, as a rule, consist of a platform and a payload system. But in the whole process of UASV navigation, autonomous mooring is also an important part. And there are fewer studies on the automatic mooring algorithm of UASV. The advanced technology of autonomous mooring of BPNS can effectively reduce the cost of human, material and financial resources, while reducing the accident rate in a reasonable and safe manner. Therefore, it is very important to comprehensively promote the development of autonomous navigation and mooring technology of UASV. Keywords: Autonomous unmanned surface vessel (UASV), autonomous mooring.
NEW MATHEMATICAL MODELS OF THE THRUST COEFFICIENT AND THE TORQUE COEFFICIENT ON THE SHIP'S PROPELLER SHAFT
Authors: Kryvyi O. F. , Miyusov M. V.
Published: March 2024

Solving the problems of course stabilization of the ship, dynamic positioning, the ship divergence dynamics, the construction of effective simulators and autopilots are not possible without the use of adequate mathematical models of the dynamics of the ship. The presence of the latter is also a necessary condition for studying various ship maneuvers, in particular, such as circulation, Kempf zigzag, slowing down, acceleration, etc. Improving control methods, including trends towards full autonomy of ships, necessitates constant improvement of mathematical models of the ship's propulsion complex. The general mathematical model of ship dynamics includes mathematical models of inertial and non-inertial forces acting on the ship. The latter include, in particular, hydrodynamic forces on the hull, forces caused by the operation of the ship's rudders and propellers, aerodynamic forces acting on the ship's hull, and forces caused by the ship's sailing rig. Mathematical models for non-inertial forces have an empirical multilevel character, include mathematical models of various quantities and parameters, and are built on the basis of experimental data processing or methods of computational hydrodynamics. Therefore, the improvement and refinement of each such model leads to the improvement of the mathematical model as a whole and is an important scientific and actual practical task. An important task is also to bring the specified mathematical models to a form that is convenient for use. In this work, new adequate, easy-to-use, mathematical models of the thrust coefficient of the propeller and the torque coefficient on the propeller shaft were obtained using regression analysis methods, and their excellent consistency with known mathematical models was shown on specific examples. For the main types of commercial vessels, the numerical values of the coefficients of the models are given, and the values of the propeller advance ratio of the zero thrust and zero torque on the propeller shaft are determined. This made it possible to obtain the condition of normal accident-free operation of the propulsion complex of the ship, which must be satisfied by the speed of the ship and the frequency of rotation of the propeller shaft, at different values of the drift angle and angular speed. Keywords: mathematical models, ship propellers, propeller thrust coefficients, propeller shaft torque coefficients.
ROOT CAUSE ANALYSIS (RCA) AS AN EFFECTIVE COGNITIVE METHOD IN CONTENT AND LANGUAGE INTEGRATED LEARNING (CLIL)
Authors: Monastyrska O. , Chesnokova M.
Published: March 2024

This article considers Content and Language Integrated Learning (CLIL) as a dual-focused educational approach in which Maritime English is used for the learning and teaching of both content and language. In maritime business English is applied as a lingua franca because this field requires an English-language-proficient workforce. Authors' teaching experience with navigational students at the National University “Odessa Maritime Academy” shows that to achieve professional competence on operational and management levels using English as the main communicative tool, students have to be intellectually challenged in order to transform information and ideas, to solve problems based on their situational awareness. Effective content learning should be applied through creative thinking, problem-solving and cognitive challenge. A navigator must figure out the cause of the problem and the processes that will help him to survive and save the property and crew. The technique of Root Cause Analysis (RCA) is widely used in all spheres of life and science as an effective method of predicting, analyzing, and summarizing the facts and building a clear paradigm to solve professional tasks. RCA has proven to be a powerful loss-prevention tool and allows crewmembers to discover the true root cause of a casualty. The problem-solving approach focuses on the analytical and cognitive ability of navigators to find correct professionallygrounded solutions based on good seamanship on board the vessel. Keywords: Maritime English, situational awareness, content, cognition, problem-solving task, case-history, creative thinking, root cause, accident investigation.
PECULIARITIES OF PLANNING THE WAYS COORDINATES OF TRAJECTORY POINTS OF AN AUTONOMOUS VESSEL CONSIDERING NAVIGATIONAL RISKS
Authors: Muravyov G. M.
Published: March 2024

Marine autonomous surface vessels came both numerous advantages and critical dangers that must be addressed early. The accident rate of autonomous vessels during the voyage cycle has an elevated level of navigational risk and the impact of cyberattacks due to the large number of receivers and transmitters of the maneuvering parameter control system and motion control coordinates along the planned trajectory. To organize accident-free navigation, it is necessary to perform highprecision planning of path coordinates using the method of trajectory points (TP), which takes into account the geometry of the path and the characteristics of the vessel. After this, it is necessary to identify hazardous areas by engineering means, determine the type of navigational risks, and plan ways to manage their level, to prepare shore operators and automatic ship control systems for maneuvering under the conditions of risks that may occur during its use. The solution to this problem should begin with the compilation of a generalized table of navigational risks and their percentage probability, and methods that will help avoid risks. One of the modern methods of determining risks is the engineering method of managing navigational risks, which determines the frequency of occurrence of various kind of risks and allows to provide preventive methods for the safe use of autonomous vessels by managing of their level. The methods of determining main navigational risks were proposed in this research, as well as systems of planning them in order to ensure the proper control. The obtained results can be used to ensure the navigational safety of autonomous vessels and also to improve methods of navigational risks planning and management by their level in the context of autonomous vessels application. Keywords: navigation risks, engineering method, safety planning of the trajectory points, managing by the safety level of autonomous ships.

Mobile and information technology have reconfigured the global towards a digital system including the digital economy and its payment technology through mobile applications and social media. COVID-19 pandemic has triggered all parties to accelerate and expand IT-based and digital services. The limited of studies related to Islamic Fintech in Indonesia is the main reason for writing this article. Continuing the previous research, it is known that Indonesia in general has followed the era with many Fintechs and startups growing. However, there are still very few Sharia-based services. After conducting online surveys with a number of agencies such as OJK, Fintech Islami Indonesia, it is known that 10 out of 121 Fintechs operate or serve sharia schemes. They provide financial services for:  SMEs and MSMEs (60.00%), General or Consumptive Financing (30.00%), and Property (30.00%), followed by Umrah and Hajj (20.00%), Education (10.00%), and Health (10.00%). Most of the Indonesian sharia fintech (60%) already have mobile-based applications, both Android and iOS. The most widely used social media are Instagram and Facebook, in addition to Twitter, LinkedIn, WhatsApp, and YouTube. In the future, it is hoped that more Indonesian Islamic Fintechs include those serving other sectors such as Agriculture, Forestry, Maritime Affairs and Fisheries, linked to crypto-currency, etc.

The longer the function of the gadget, the more sophisticated it causes changes in behavior that are different from before, sometimes even confusing in determining good attitudes and behavior according to them. The value of multiple and not absolute behavior due to changes in the function of gadgets causes housewives to reject the latest gadgets because they harm the behavior and values they believe in. This research was conducted on several housewives. Data was collected using a qualitative approach, through interviews and direct observation of housewives. The data were analyzed using a descriptive study of modern socio-economic theory to see how housewives respond to the development of gadgets. The results showed that housewives had excessive concerns about the progress of gadgets, so they tended to reject these advances. More relented to have the latest gadgets, and do not know how to use gadgets in order to take opportunities in empowering the creative economy. This study uses an economic sociology study, to be able to provide a more comprehensive analysis in looking at the phenomenon of housewives in urban areas.

Aims: The styloid process is a cylindrical projection of the temporal bone. When the length of the styloid process exceeds 30 mm, it is considered elongated. The aim of this study was to investigate the length, thickness and morphological pattern of the styloid process of patients using panoramic radiography and to evaluate the relationship with age and gender.

Methods: The study is designed retrospective cross-sectional and consisted of 3012 panoramic radiographs from patients routinely referred within the last six months, in which the borders of the styloid process region were clearly visualised on radiographs. Age and gender data of the patients were recorded. Styloid process was evaluated in terms of length, thickness and Langeais classification.

Results: The mean age of the patients was 38.32 years. 34.4% (n:1156) were male and 61.6% (n:1856) were female. The mean styloid process length was >30 for 32% of the patients. The thickness of the right styloid process was 2.73±1.56 and that of the left styloid process was 2.69±1.5. The length of the styloid process ranged between 0-79.98 mm with a mean of 26.12±10.78 mm. Most of the patients were in Langeais Type 1 class in right and left styloid process. There was a statistically significant correlation between the length, thickness and Langeais classification of right and left styloid process (p

Aims: The aim of this study was to compare TAPP and TEP techniques, which are laparoscopic inguinal hernia repair techniques. In this study, it was tried to determine whether one technique has an advantage over the other in terms of surgery, hospitalization and recovery times, recurrence, postoperative bleeding and testicular edema.

Methods: Totally 62 patients who underwent laparoscopic inguinal hernia repair between January 2015 and January 2020 were included in this retrospective study.

Results: Among the patients who underwent TAPP and TEP operations; it was determined that there was no significant difference in terms of operation time, recovery time, hospital stay, recurrence and complications (p>0.05).

Conclusion: Based on the results of this study, TEP and TAPP are equally effective and safe as laparoscopic hernia repair surgery. The choice of which approach to perform can be made according to the skill and preference of the surgeon.

Exercise benefits and barriers perceived by hemodialysis patients: relationship with fatigue and physical activity level
Authors: Aktaş Arslan Fatma Cansu , Düger Tülin
Published: March 2024

Aims: The aim of our study was to determine the attitudes of hemodialysis (HD) patients towards exercise and to determine the relationship between physical activity level (PAL) and fatigue.

Methods: This cross-sectional study was conducted with 113 HD patients (57.8±5.96) aged 18-65 years. Personal information form, fatigue impact scale (FIS), international physical activity questionnaire short form (IPAQ-SF), and dialysis patient-perceived exercise benefits and barriers scale (DPEBBS) were used as data collection tools.

Results: The mean DPEBBS total score was 64.35±6.15 and PAL was low. The most commonly perceived exercise benefits were preventing muscle atrophy and maintaining a stable body weight, while the most common exercise barriers (EB) were not understanding how to exercise and fatigue. There was a weak negative correlation between the PAL of the patients with the Perceived Exercise Barriers subscale (r=-0.275, p=0.003) and a weak positive correlation between the total scale score (r=0.318, p=0.001). There was a weakly significant positive correlation between the Cognitive, Physical, Psychosocial sub-dimension of Fatigue and Total FIS with the Perceived Exercise Barriers sub-dimension (r=0.337, p=0.000; r=0.358, p=0.000; r=0.334, p=0.000; r=0.387, p=0.000). A very weakly significant negative correlation was found between the Fatigue Cognitive, Physical, Psychosocial sub-dimension and Fatigue Total Impact Dimension with the total scale score (r=-0.247, p=0.008; r=-0.234, p=0.013), r=-0.222, p=0.018, r=-0.243, p=0.003) .

Conclusion: HD patients had higher perceptions of the benefits of exercise. It was concluded that the perception of EB decreased as PAL increased and the perception of EB increased as fatigue levels increased. It is recommended that specialized physiotherapists evaluate HD groups at risk in detail and create individual interventions that support HD patients' compliance with exercise.
Frequency of seronegative cases in autoimmune hepatitis and their association with the systemic immune inflammation index
Authors: Mutlu Bilgiç Nermin
Published: March 2024

Aims: It is suggested that a deficiency in B cells plays a role in pathogenesis of seronegative autoimmune hepatitis (snAIH). The lack of B cells leads to notable changes in the variety of leukocyte types within the bloodstream. This study aimed to determine the frequency of snAIH in patients with autoimmune hepatitis, as well as to explore the relationship between snAIH and leukocyte-based inflammatory indices.

Methods: In this retrospective study, 57 patients newly diagnosed with autoimmune hepatitis were included. According to clinical and pathological findings, patients were classified into seropositive autoimmune hepatitis (spAIH) and snAIH groups. The inflammation indices included the platelet to lymphocyte ratio (PLR), the neutrophil to lymphocyte ratio (NLR), and the systemic immune-inflammation index (SII).

Results: The frequency of snAIH was 26.3%. The snAIH group exhibited higher NLR (3.0 vs. 1.5, p
