Published: April 2024

The operational efficacy of lane departure warning systems (LDWS) in autonomous vehicles is critically influenced by the retro-reflectivity of road markings, which varies with environmental wear and weather conditions. This study investigated how changes in road marking retro-reflectivity, due to factors such as weather and physical wear, impact the performance of LDWS. The study was conducted at the Yeoncheon SOC Demonstration Research Center, where various weather scenarios, including rainfall and transitions between day and night lighting, were simulated. We applied controlled wear to white, yellow, and blue road markings and measured their retro-reflectivity at multiple stages of degradation. Our methods included rigorous testing of the LDWS’s recognition rates under these diverse environmental conditions. Our results showed that higher retro-reflectivity levels significantly improve the detection capability of LDWS, particularly in adverse weather conditions. Additionally, the study led to the development of a simulation framework for analyzing the cost-effectiveness of road marking maintenance strategies. This framework aims to align maintenance costs with the safety requirements of autonomous vehicles. The findings highlight the need for revising current road marking guidelines to accommodate the advanced sensor-based needs of autonomous driving systems. By enhancing retro-reflectivity standards, the study suggests a path towards optimizing road safety in the age of autonomous vehicles.

Published: April 2024

Electric-field energy harvesters (EFEHs) have emerged as a promising technology for harnessing the electric field surrounding energized environments. Current research indicates that EFEHs are closely associated with Tribo-Electric Nano-Generators (TENGs). However, the performance of TENGs in energized environments remains unclear. This work aims to evaluate the performance of TENGs in electric-field energy harvesting applications. For this purpose, TENGs of different sizes, operating in single-electrode mode were conceptualized, assembled, and experimentally tested. Each TENG was mounted on a 1.5 HP single-phase induction motor, operating at nominal parameters of 8 A, 230 V, and 50 Hz. In addition, the contact layer was mounted on a linear motor to control kinematic stimuli. The TENGs successfully induced electric fields and provided satisfactory performance to collect electrostatic charges in fairly variable electric fields. Experimental findings disclosed an approximate increase in energy collection ranging from 1.51% to 10.49% when utilizing TENGs compared to simple EFEHs. The observed correlation between power density and electric field highlights TENGs as a more efficient energy source in electrified environments compared to EFEHs, thereby contributing to the ongoing research objectives of the authors.

Published: April 2024

The Internet of Things (IoT) will bring about the next industrial revolution in Industry 4.0. The communication aspect of IoT devices is one of the most critical factors in choosing the device that is suitable for use. Thus far, the IoT physical layer communication challenges have been met with various communications protocols that provide varying strengths and weaknesses. This paper summarizes the network architectures of some of the most popular IoT wireless communications protocols. It also presents a comparative analysis of some of the critical features, including power consumption, coverage, data rate, security, cost, and quality of service (QoS). This comparative study shows that low-power wide area network (LPWAN)-based IoT protocols (LoRa, Sigfox, NB-IoT, LTE-M) are more suitable for future industrial applications because of their energy efficiency, high coverage, and cost efficiency. In addition, the study also presents an Industrial Internet of Things (IIoT) application perspective on the suitability of LPWAN protocols in a particular scenario and addresses some open issues that need to be researched. Thus, this study can assist in deciding the most suitable IoT communication protocol for an industrial and production field.

Authors: Enkhbat Avirmed , Shih Timothy K. , Cheewaprakobkit Pimpa
Published: April 2024

Human action recognition (HAR) is growing in machine learning with a wide range of applications. One challenging aspect of HAR is recognizing human actions while playing music, further complicated by the need to recognize the musical notes being played. This paper proposes a deep learning-based method for simultaneous HAR and musical note recognition in music performances. We conducted experiments on Morin khuur performances, a traditional Mongolian instrument. The proposed method consists of two stages. First, we created a new dataset of Morin khuur performances. We used motion capture systems and depth sensors to collect data that includes hand keypoints, instrument segmentation information, and detailed movement information. We then analyzed RGB images, depth images, and motion data to determine which type of data provides the most valuable features for recognizing actions and notes in music performances. The second stage utilizes a Spatial Temporal Attention Graph Convolutional Network (STA-GCN) to recognize musical notes as continuous gestures. The STA-GCN model is designed to learn the relationships between hand keypoints and instrument segmentation information, which are crucial for accurate recognition. Evaluation on our dataset demonstrates that our model outperforms the traditional ST-GCN model, achieving an accuracy of 81.4%.
Brake Fluid Condition Monitoring by a Fiber Optic Sensor Using Silica Nanomaterials as Sensing Components
Authors: Ibrahim Mayza , Petrík Stanislav
Published: April 2024

In the automotive industry, there has been considerable focus on developing various sensors for engine oil monitoring. However, when it comes to monitoring the condition of brake fluid, which is crucial for ensuring safety, there has been a lack of a secure online method for this monitoring. This study addresses this gap by developing a hybrid silica nanofiber mat, or an aerogel integrated with an optical fiber sensor, to monitor brake fluid condition. The incorporation of silica nanofibers in this hybrid enhances the sensitivity of the optical fiber glass surface by at least 3.75 times. Furthermore, creating an air gap between the glass surface of the optical fiber and the nanofibers boosts sensitivity by at least 5 times, achieving a better correlation coefficient (R2 = 0.98). In the case of silica aerogel, the sensitivity is enhanced by 10 times, but this enhancement relies on the presence of the established air gap. The air gap was adjusted to range from 0.5 mm to 1 mm, without any significant change in the measurement within this range. The response time of the developed sensor is a minimum of 15 min. The sensing material is irreversible and has a diameter of 2.5 mm, making it easily replaceable. Overall, the sensor demonstrates strong repeatability, with approximately 90% consistency, and maintains uncertainty levels below 5% across specific ranges: from 3% to 6% for silica aerogel and from 5% to 6% for silica nanofibers in the presence of an air gap. These findings hold promise for integrating such an optical fiber sensor into a car’s electronic system, enabling the direct online monitoring of brake fluid quality. Additionally, the study elucidates the effect of water absorption on the refractive index of brake fluid, as well as on the silica nanomaterials.

Authors: Duan Zongchao , Ren Feilong , Qiang Li-E , Qi Keqi , Zhang Haoyue
Published: April 2024

Temperature fluctuations affect the performance of high-precision gravitational reference sensors. Due to the limited space and the complex interrelations among sensors, it is not feasible to directly measure the temperatures of sensor heads using temperature sensors. Hence, a high-accuracy interpolation method is essential for reconstructing the surface temperature of sensor heads. In this study, we utilized XGBoost-LSTM for sensor head temperature reconstruction, and we analyzed the performance of this method under two simulation scenarios: ground-based and on-orbit. The findings demonstrate that our method achieves a precision that is two orders of magnitude higher than that of conventional interpolation methods and one order of magnitude higher than that of a BP neural network. Additionally, it exhibits remarkable stability and robustness. The reconstruction accuracy of this method meets the requirements for the key payload temperature control precision specified by the Taiji Program, providing data support for subsequent tasks in thermal noise modeling and subtraction.
On a Closer Look of a Doppler Tolerant Noise Radar Waveform in Surveillance Applications

Published: April 2024

The prevalence of Low Probability of Interception (LPI) and Low Probability of Exploitation (LPE) radars in contemporary Electronic Warfare (EW) presents an ongoing challenge to defense mechanisms, compelling constant advances in protective strategies. Noise radars are examples of LPI and LPE systems that gained substantial prominence in the past decade despite exhibiting a common drawback of limited Doppler tolerance. The Advanced Pulse Compression Noise (APCN) waveform is a stochastic radar signal proposed to amalgamate the LPI and LPE attributes of a random waveform with the Doppler tolerance feature inherent to a linear frequency modulation. In the present work, we derive closed-form expressions describing the APCN signal’s ambiguity function and spectral containment that allow for a proper analysis of its detection performance and ability to remove range ambiguities as a function of its stochastic parameters. This paper also presents a more detailed address of the LPI/LPE characteristic of APCN signals claimed in previous works. We show that sophisticated Electronic Intelligence (ELINT) systems that employ Time Frequency Analysis (TFA) and image processing methods may intercept APCN and estimate important parameters of APCN waveforms, such as bandwidth, operating frequency, time duration, and pulse repetition interval. We also present a method designed to intercept and exploit the unique characteristics of the APCN waveform. Its performance is evaluated based on the probability of such an ELINT system detecting an APCN radar signal as a function of the Signal-to-Noise Ratio (SNR) in the ELINT system. We evaluated the accuracy and precision of the random variables characterizing the proposed estimators as a function of the SNR. Results indicate a probability of detection close to 1 and show good performance, even for scenarios with a SNR slightly less than −10 dB. The contributions in this work offer enhancements to noise radar capabilities while facilitating improvements in ESM systems.

Published: April 2024

The absence of some forms of non-verbal communication in virtual reality (VR) can make VR-based group discussions difficult even when a leader is assigned to each group to facilitate discussions. In this paper, we discuss if the sensor data from off-the-shelf VR devices can be used to detect opportunities for facilitating engaging discussions and support leaders in VR-based group discussions. To this end, we focus on the detection of suppressed speaking intention in VR-based group discussions by using personalized and general models. Our extensive analysis of experimental data reveals some factors that should be considered to enable effective feedback to leaders. In particular, our results show the benefits of combining the sensor data from leaders and low-engagement participants, and the usefulness of specific HMD sensor features.

Authors: Mochurad Lesia
Published: April 2024

The growing demand for high-quality video transmission over bandwidth-constrained networks and the increasing availability of video content have led to the need for efficient storage and distribution of large video files. To improve the latter, this article offers a comparison of six video compression methods without loss of quality. Particularly, H.255, VP9, AV1, convolutional neural network (CNN), recurrent neural network (RNN), and deep autoencoder (DAE). The proposed decision is to use a dataset of high-quality videos to implement and compare the performance of classical compression algorithms and algorithms based on machine learning. Evaluations of the compression efficiency and the quality of the received images were made on the basis of two metrics: PSNR and SSIM. This comparison revealed the strengths and weaknesses of each approach and provided insights into how machine learning algorithms can be optimized in future research. In general, it contributed to the development of more efficient and effective video compression algorithms that can be useful for a wide range of applications.

Published: April 2024

Organophosphate esters (OPEs) are frequently used as flame retardants and plasticizers in various commercial products. While initially considered as substitutes for brominated flame retardants, they have faced restrictions in some countries due to their toxic effects on organisms. We collected 37 soil and crop samples in 20 cities along the coast of South China, and OPEs were detected in all of them. Meanwhile, we studied the contamination and potential human health risks of OPEs. In soil samples, the combined concentrations of eight OPEs varied between 74.7 and 410 ng/g, averaging at 255 ng/g. Meanwhile, in plant samples, the collective concentrations of eight OPEs ranged from 202 to 751 ng/g, with an average concentration of 381 ng/g. TDCIPP, TCPP, TCEP, and ToCP were the main OPE compounds in both plant and soil samples. Within the study area, the contaminants showed different spatial distributions. Notably, higher OPEs were found in coastal agricultural soils in Guangdong Province and crops in the Guangxi Zhuang Autonomous Region. The results of an ecological risk assessment show that the farmland soil along the southern coast of China is at high or medium ecological risk. The average non-carcinogenic risk and the carcinogenic risk of OPEs in soil through ingestion and dermal exposure routes are within acceptable levels. Meanwhile, this study found that the dietary intake of OPEs through food is relatively low, but twice as high as other studies, requiring serious attention. The research findings suggest that the human risk assessment indicates potential adverse effects on human health due to OPEs in the soil–plant system along the coast of South China. This study provides a crucial foundation for managing safety risks in agricultural operations involving OPEs.

Soil-transmitted helminth (STH) infections are caused by roundworms, hookworms, whipworms, and thread worms. Accurate diagnosis is essential for effective treatment, prevention, and control of these infections. This study evaluates a new diagnostic method called Single-image Parasite Quantification (SIMPAQ), which uses a lab-on-a-disc (LoD) technique to isolate STH eggs into a single imaging zone for digital analysis. The study evaluates the purification performance of the SIMPAQ technique for detecting STH eggs in animal samples. This was a cross-sectional study conducted among 237 pigs and 281 dogs in the Morogoro region in Tanzania. Faecal samples were collected and processed with the LoD technique, as well as flotation and McMaster (McM) methods for comparison purposes. The overall prevalence of STH infections was high as per the LoD technique (74%), followed by McM (65.44%) and flotation (65.04%). Moreover, the overall performance of the LoD technique, using McM as the gold standard, was 93.51% (sensitivity), 60.89% (specificity), 81.91% (PPV), and 83.21% (NPV). The LoD technique exhibited high prevalence, sensitivity, and NPV, which demonstrates its value for STH egg detection and its crucial role in the era of accurate STH diagnosis, promoting proper management of the infection.

Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) play key roles in regulating testosterone secretion and spermatogenesis in male mammals, respectively, and they maintain the fertility of male animals by binding to their corresponding receptors. We designed and prepared a recombinant LH receptor (LHR) subunit vaccine and a recombinant FSH receptor (FSHR) subunit vaccine and used male Sprague Dawley (SD) rats as a model to examine their effects on testicular development, spermatogenesis, and testosterone secretion in prepubertal and pubertal mammals. Both vaccines (LHR-DTT and FSHR-DTT) significantly decreased the serum testosterone level in prepubertal rats (p < 0.05) but had no effect on the testosterone secretion in pubertal rats; both vaccines decreased the number of cell layers in the seminiferous tubules and reduced spermatogenesis in prepubertal and pubertal rats. Subunit vaccine FSHR-DTT decreased the sperm density in the epididymis in both prepubertal and pubertal rats (p < 0.01) and lowered testicular index and sperm motility in pubertal rats (p < 0.05), whereas LHR-DTT only reduced the sperm density in the epididymis in pubertal rats (p < 0.05). These results indicate that the FSHR subunit vaccine may be a promising approach for immunocastration, but it still needs improvements in effectiveness.

Published: April 2024

A 13-month-old, neutered, male, domestic shorthair cat was referred with a history of progressive paraparesis, proprioceptive ataxia, and lumbar spinal pain. Neurological examination revealed non-ambulatory paraparesis consistent with L4-S1 myelopathy. Magnetic resonance of the thoracolumbar spinal cord identified a dorsal intradural extramedullary space-occupying lesion extending from L5 to L6. It was homogeneously hyperintense in T2-weighted imaging and isointense in T1-weighted imaging and exhibited marked and homogeneous contrast enhancement in the T1-weighted post-contrast imaging. The removed tissue was composed of neoplastic cells arranged as pseudostratified or multilayered trabecular and tubular structures, supported by internal and external limiting PAS-positive membranes. The neoplastic cells were immunoreactive for vimentin and NSE and negative for GFAP, Olig2, synaptophysin, PCK, S-100, NeuN, and nestin. The Ki-67 nuclear labeling index was up to 90%. The tumor was consistent with the diagnosis of medulloepithelioma, which is most frequently reported as an intraocular tumor. The morphological and immunohistochemical features of the tumor showed remarkable concordance with most human medulloepitheliomas. This is the first spinal cord medullopethelioma report in a cat, with the clinical, neuroradiological, histological, and immunohistochemical findings being described.
Assessing salivary innate immune responses in adolescents with dentofacial abnormalities and central precocious puberty
Authors: Kolesnik K. A. , Belousova A. M.
Published: April 2024

Relevance. Central precocious puberty (CPP), characterized by a high incidence of 60% among endocrinopathies during puberty, significantly influences dentofacial development and the local immune defense mechanisms in adolescents. However, the impact on saliva's innate immune function remains underexplored.

This study aims to evaluate the innate immune function of saliva in individuals with CPP coexisting with dentofacial abnormalities.

Materials and methods. An analysis of saliva biochemical markers was conducted on 59 adolescents diagnosed with CPP and dentofacial abnormalities, alongside a control group of 21 age-matched individuals with dentofacial abnormalities but without systemic conditions, aged 13-18 years. The evaluation focused on lysozyme and urease levels, dysbiosis markers indicating oral microbiota status, malondialdehyde (MDA) levels, and catalase activity to gauge the balance between pro-oxidant and antioxidant systems, alongside proteolytic enzyme elastase activity.

Results. Adolescents with combined CPP and dentofacial abnormalities exhibited weakened antioxidant and antibacterial defenses, evidenced by decreased catalase activity (0.105 ± 0.020 mkat/l, p < 0.001) and lysozyme levels (54.7 ± 3.2 U/l, p < 0.02), against a backdrop of increased lipoperoxidation and microbial contamination (MDA levels at 0.48 ± 0.11 μmol/l, p < 0.05, urease levels at 0.713 ± 0.015 μkat/l, p < 0.01), and heightened inflammation (elastase activity up to 2.71 ± 0.12 μkat/l, p < 0.01).

Conclusion. The diminished innate immune function in saliva necessitates the development of strategies to enhance it, serving as a preventive measure against gingivitis in patients with CPP.
GPs’ experience with diagnosis and treatment guidelines for lower UTI in men: a qualitative interview
Authors: Kornfält Isberg Helena , Gröndal Hedvig , Tyrstrup Mia
Published: April 2024

Background

The incidence of lower urinary tract infection (LUTI) in men visiting primary health care (PHC) is low. Hence, GPs do not diagnose and treat men with LUTI very often. Previous studies have shown that adherence to treatment guidelines regarding LUTI in men is low. There is limited knowledge concerning why guidelines are not adhered to.

Aim

To gain knowledge on GPs’ experiences and concerns when treating men with LUTI, including their use of clinical guidelines. Furthermore, this study aimed to explore GPs’ knowledge and concern regarding antibiotic resistance.

Design & setting

A qualitative study based on semi-structured interviews with GPs was performed.

Method

15 GPs from seven PHC centres (PHCC) in southern Sweden were interviewed. The interviews were conducted from September 2022 to March 2023. All interviews were audio recorded and transcribed verbatim. A thematic analysis was performed.

Results

GPs had limited experience with and felt less certainty when diagnosing male LUTI. Extended examinations could partially relieve this feeling. GPs were well informed about the Swedish treatment guidelines for LUTI in men and felt safe to treat their patients according to the guidelines. However, GPs also acknowledged that guidelines do not cover all situations and need to be individualised.

Conclusion

Many GPs feel insecure when diagnosing male LUTI. The relatively low prevalence of this condition in PHC could contribute to this feeling. Clear and instructive guidelines regarding both the diagnostic process and adequate antibiotic choices are important to maintain good quality in the management of LUTI in men.

In today's conditions, it is important to research the actual instruments of financial policy formation and ways of its improvement, which will effectively influence the development of the financial mechanism. The search for ways to improve financial policy at the current stage of economic development requires constant analysis and study in order to adjust the financial mechanism in response to external and internal factors. Since the full-scale invasion of the aggressor country on the territory of our state, there has been a need to develop a new mechanism of financial policy, which involves the search for additional sources of filling the state budget, revision of previously adopted normative legal acts and attraction of international financial assistance. The authors of the article considered the state and prospects for the development of the state's financial policy under the influence of external and internal factors. The challenges faced by the economy and ways to overcome them are analyzed. The legislative framework that will improve the mechanism of financial policy has been studied.

In a broad and general sense, hospitality services are components of tourist services, and their quality shapes and influences consumer behavior, the level of service and comprehensive development of tourism and its products. Hotels and tourism also create a positive impact on the economy of many countries or regions. But now, due to the prolonged state of war and the consequences of the COVID-19 pandemic, domestic tourism is still experiencing difficult times. Many hotels and other tourism-related businesses experience the problems that lead to the reduction of their network, and in the most critical case - to closure. These risks create difficulties for people who work in the tourism industry or interact with it as counterparties. Our task is to diagnose the external competitive advantages of the hotel infrastructure and justify their consideration in relation to the potential behavior of consumers of hospitality and tourism services in order to successfully operate the respective destinations, using the example of the mountain resort of Mygove, Chernivtsi region. In the process of carrying out the research, literary, analysis, synthesis, induction, deduction, and analogy methods were used; specifically scientific: factor analysis and statistical methods. The article examines the methodology of diagnosing external competitive advantages of hotel infrastructure and substantiating their application in tourism for the purpose of successful functioning of relevant destinations and the state of hotel infrastructure on the example of the mountain tourist resort of Mygove, Chernivtsi region. The results of the scientific research can be used by local self-government bodies for the development and justification of long-term strategic plans for the organization, management and development of the tourist business and hotel infrastructure of the Mygove mountain resort in the conditions of the influence of various factors on the behavior of tourists as potential consumers. Theoretical, methodological and applied developments, together with the obtained results, can be used in similar studies for other regions in overcoming crisis phenomena of the tourism and hotel business caused by pandemics, martial law in Ukraine and abroad.

Se presentan los primeros resultados obtenidos del relevamiento arquitectónico realizado en Tambo de Ranchillos (Uspallata, Mendoza), en el marco del proyecto “Patrimonio Arqueológico Incaico en el Parque Nacional de la Defensa Uspallata. Análisis Arquitectónico y Plan de Manejo y Conservación”. El objetivo de este trabajo es discutir la aplicación de categorías arquitectónicas tradicionales en el contexto de la elaboración de un programa de monitoreo; y proponer nuevas categorías desde una perspectiva que integre los modos constructivos presentes. Para ello, se realizó un análisis desde diversas escalas: Unidades Murarias (UM), Recintos (R) y Unidades Arquitectónicas (UA). Los resultados obtenidos muestran que Ranchillos es un sitio arqueológico en el que conviven diferentes técnicas constructivas, que dan como resultado la presencia de recintos morfológicamente diferentes y de un alto grado de variabilidad en lo referente a las unidades arquitectónicas. Los resultados permiten avanzar en el desarrollo de un programa de monitoreo para optimizar la toma de decisiones de conservación sobre sectores puntuales del sitio en base al conocimiento tanto de los tipos de muro según sus características constructivas, como de los tipos de muro según su función y relación dentro de cada conjunto arquitectónico.
Italy between history and historiography. In search of national identity
Authors: Trotta Marco
Published: April 2024

Starting from the fundamental studies of the historian Giuseppe Galasso and in the context of a close confrontation with the most experienced European historiography on these topics, the essay reconstructs some issues of the italian national identity through the different guidelines of the historiographical debate from the nineteenth century to today in a comparative and historical setting of european modernity. The centuries-old duration of the events related to the process of formation of the Italian identity, from the tradition of the Roman Empire to the Risorgimento and national independence, passing through the long domination of foreign powers, finally ended with the unification of the peninsula and the state-building in 1861. The most significant terms of the identity discourse are thus affirmed: territory and nation, whose underlying grounds, however, still struggle to find shared reasons for a unitary understanding of the national historical framework. In this respect the category of national identity starts its construction at the time of the Romantic ferments and remains intimately linked to those anthropological traits that would have provided to found in the mid-nineteenth century the community of Italians, finally rejoined under the frame of a new State. Not a single identity, therefore, but a multiplicity of references to the rich, centuries-old Italian cultural heritage, rethought in the light of a decisive season for national destinies.
Health Literacy, Migration Traumas, Narrative Medicine and the Language Desk. New practices in translingualism and educational processes
Authors: Sgaglione Andreina
Published: April 2024

Health literacy (HL) is a complex field encompassing a range of public health education and communication activities that are crucial for interacting with the health care system. In a sustainable world, future healthcare must be accessible to all, and we must ensure that people from migrant backgrounds have got the resources to manage their health. Inequalities in immigrants’ health profiles, a sign of ineffective integration policies, could be mitigated by improving HL levels. The aim of the study was to investigate the space given to HL within formal immigrant learning contexts; the study featured a questionnaire that was intended as a probe into some specific needs and discomforts connected with the condition of translingualism and with the related trauma, which may have a negative impact on language learning. Such interweaving offers a different perspective that generates new teaching practices and the creation of a Language Desk that through language, health literacy and narrative medicine promotes equitable, safe and sustainable learning contexts that enhance the experience of translingualism in all its forms.

Authors: Jesmi Ali Asghar , Taj Ali , Ardane Fateme
Published: April 2024

Background: Brain injury and coma after trauma are major health problems all over the world as the hemodynamic indicators of patients fluctuate and their clinical conditions deteriorate. Consequently, the demand for professional care will increase. Accordingly, this study aimed to explain the experiences of people caring for comatose patients with head injury. Methods: The present study was conducted using a conventional qualitative content analysis approach. The participants were selected through purposive sampling and the sampling process continued until data saturation. A total of 17 nurses and 3 head nurses working in the intensive care units (ICUs) of Sabzevar University of Medical Sciences in 2022 participated in the study. Results: Data analysis led to the identification of three main categories and nine subcategories including clarification of needs (understanding patients’ needs based on symptoms, intensive vision, application of care knowledge), continuous care to facilitate transition (skilled and quality care, progress monitoring, continuity in care and teamwork), and empathic support (living in the patient’s world, therapeutic relationship, and conscience-oriented actions. As a result, "targeted care" was detected as the main theme of the study. Conclusion: According to the results of the current study, in order for nurses to perform targeted care to get patients out of critical situations as quickly as possible, first a detailed examination is required to identify the patients’ needs and problems. Then, continuous nursing care with comprehensive support should be provided to the patients. The results of this study can instill motivation in care and improve its quality, ultimately leading to patient-centered nursing and treatment.
