The influence of the circular distribution of radial and tangential seismic velocity on the structural safety of residential buildings
Authors: Chrzan Tadeusz
Published: March 2023

The article presents the results of conditions of circular distribution of seismic vibrations generated during rock blasting. The Scales of Dynamic Influences [SWD] of the harmfulness of the vibration velocity on a two-storey building [SWDI] and a five-storey building[SWDII] are given. The value of seismic velocity safe for the construction of the buildings has been determined. They are in Zone II of the Dynamic Influence Scale [SWD] SWD I and SWD II. The magnitude of the components of the vibration velocity at the same distance from the source of vibration depends on the directional angle between the line of blast holes and the line connecting the centre of the surface of the mined rock block and the place of measurement. For the circular distribution of the vibration velocity, a theoretical analysis of the change in the radial value Vx and the tangential Vy of the vibration velocity depending on the change in the directional angle was conducted. Graphs of vibration velocity for circular distribution, measured during mining of rocks and complying with theoretical predictions were presented. For residential buildings, with SWDI and SWDII, the limit value of the safe vibration velocity for the building structures is given.

Published: March 2023

The article presents the types of the most common underground or partially sunken tanks used on farms. The analyzed tanks were designed for the storage of zoonotic fertilizers. Solid or semi-liquid fertilizers should be stored in livestock premises in sealed tanks, protected from leakage into the ground. Basic static schemes of tanks and types of loads acting on tanks were considered. The durability and leak-tightness of the tanks were also addressed, and the insulation used to protect the walls and bottom plate of the tanks was discussed. A computational example presents the values of loads acting on the various elements of the tank at two computational schemes, and compares the results obtained by two computational methods, i.e., the separated plate method and the finite element method. The discrepancies in the obtained results were pointed out. Recommendations were formulated for the design of tanks in terms of meeting the tightness criterion. FEM calculations were made for two cases: with and without consideration of the soil stiffness.
Friends With Money? A Political–Economic Analysis of Chinese Foreign Aid-Induced Tourism Demand
Authors: Yang Fiona X. , Yang Gongyan , Li Ying , Liu Yize
Published: March 2023

From a political–economic perspective, this research examines the nexus between Chinese foreign aid and tourism demand in 138 recipient countries. Specifically, it investigates two mechanisms and their interplay: (1) an economic channel that entices an influx of international tourists
through infrastructure development; and (2) a political channel that attracts Chinese tourists by diminishing political distance. A cross-country panel dataset on Chinese aid projects is analyzed. The results suggest that Chinese aid has a significant impact on Chinese tourists after a 1-year
lag through the political channel, while the economic channel’s effect on Chinese/other international tourists is not salient within 5 years. Significant long-run equilibrium relationships are found between aid and both tourist segments. The economic effect emerges in the long term,
while the political effect fades out. This study provides a novel political–economic perspective for tourism research and presents new insights into China’s soft power in global tourism.

Published: March 2023

Brain-computer interfaces (BCIs) can use data from non-invasive electroencephalogram (EEG) to transform different brain signals into binary code, often aiming to gain control utility of an end-effector (e.g mouse cursor). In the past several years, advances in wearable and immersive technologies have made it possible to integrate EEG with virtual reality (VR) headsets. These advances have enabled a new generation of user studies that help researchers improve understanding of various issues in current VR design (e.g. cybersickness and locomotion). The main challenge for integrating EEG-based BCIs into VR environments is to develop communication architectures that deliver robust, reliable and lossless data flows. Furthermore, user comfort and near real-time interactivity create additional challenges. We conducted two experiments in which a consumer-grade EEG headband (Muse2) was utilized to assess the feasibility of an EEG-based BCI in virtual environments. We first conducted a pilot experiment that consisted of a simple task of object re-scaling inside the VR space using focus values generated from the user’s EEG. The subsequent study experiment consisted of two groups (control and experimental) performing two tasks: telekinesis and teleportation. Our user research study shows the viability of EEG for real-time interactions in non-serious applications such as games. We further suggest that a simplified way of calculating the mean EEG values is adequate for this type of use. We , in addition, discuss the findings to help improve the design of user research studies that deploy similar EEG-based BCIs in VR environments.
ПРОЦЕС ПІДЙОМУ ҐРУНТУ РОБОЧИМИ ОРГАНАМИ ГРУНТООБРОБНОЇ РОЗРИХЛЮВАЛЬНО-СЕПАРУЮЧОЇ УСТАНОВКИ
Authors: Сиромятников Ю.М. , Храмов М.С.
Published: March 2023

Предметом дослідження є процес функціонування дискових робочих органів з лемешем ґрунтообробної розрихлювально-сепаруючої установки, що здійснює підйом та сепарацію. При переміщенні леміша на малих глибинах (0,03...0,1 м) рух ґрунту по ньому ускладняється через утворення ґрунтового валка, перед лемішем. Ґрунт при цьому розпушується і розсипається на сторони, не забезпечуючи необхідного підпору, для переміщення його до розрихлювально-сепаруючого пристрою. Для того, щоб ґрунт не згруджувався і не розсипався на сторони, по обидва боки леміша встановлені пасивні обертові диски. Об’єктом дослідження є дискові елементи підйомно-підрізаючого пристрою, які дозволяють суттєво підвищити ефективність технологічного процесу руху ґрунту по лемішу при одночасному зниженні питомої енергоємності. Вихідна інформація для обґрунтування дослідження отримана шляхом аналізу літературних джерел. Визначено, що збільшення радіусу паралельно розташованих вільно обертових плоских дисків з 0,175 до 0,270 м призводить до підвищення товщини шару ґрунту на леміші не більше ніж на 17%. Зі збільшенням кінематичного параметру обертання дисків від 0 до 0,6 згружування ґрунту на леміші знижується у 2,73 рази, з 0,6 до 1,0 – у 1,25 рази і з 1,0 до 1,2 – у 1,04 рази. Встановлено, що збільшення кута постановки леміша спочатку призводить до зниження рівня ґрунту на ньому і досягає мінімуму при куті, близькому до 25°. При подальшому збільшенні кута рівень ґрунту на леміші зростає. Експериментально доведено, що найбільший вплив на граничну відстань між дисками при якому підйом пласта ґрунту лемішем здійснюється без заклинювання – це вологістьґрунту. Актуальність полягає в тому, що одночасне використання пасивних дискових робочих органів разом з лемішем дозволяє вдосконалити методи передпосівного обробітку ґрунту для покращення його агротехнічного стану.
АКТИВІЗАЦІЯ СЕПАРАЦІЇ ТЕХНОЛОГІЧНОЇ МАСИ НА СЕПАРУЮЧИХ РОБОЧИХ ПОВЕРХНЯХ
Authors: Ткачук В.С. , Девін В.В. , Бурдега В.Ю.
Published: March 2023

При підкопі технологічної маси на сепаруючу робочу поверхню попадає з кожного гектару біля 1 тис. т ґрунту. Процес сепарації ускладняється ще й тим, що технологічна маса містить всього 1,5…5 % корисної продукції, і тим, що властивості ґрунту не постійні, а корисна продукція чутлива до пошкоджень. Процес відділення корисної продукції від ґрунту при сепарації полягає в руйнуванні грудок і просіванні їх через “живий” переріз сепаруючої робочої поверхні. Підвищення продуктивності роботи збиральних машин, зменшення пошкодження корисної продукції за рахунок інтенсифікації вторинної сепарації технологічної маси. Активувати процес кришення грудок можливо поперечними коливаннями сепаратора. Розглянуто “одиничні” акти взаємодії, “грудка-пруток”, “грудка-грудка”, “грудка-корисна продукція” і т.п.. Зрозуміло, що в реальній ситуації розглянуті одиничні акти взаємодії недостатньо точно описують весь процес сепарації. Тому слід застосувати деякі інтегральні підходи, які б усереднювали ті чи інші фізико-механічні властивості суміші. За результатами теоретичних досліджень можна зробити такі припущення: підвищення ефективності сепарації ґрунту за рахунок використання сепаруючої робочої поверхні із поперечними коливаннями і встановлення площини сепаратора під кутом до поверхні поля є можливим; теоретично граничні параметри, на підставі непрямих чинників, частота і амплітуда коливань ( = 10…25 Гц, А = 6…18 мм), кут нахилу площини сепаратора в поздовжньому напрямку і швидкість руху агрегату (подача технологічної маси) вибирається із умови оптимального завантаження сепаратора ( = 5…15 град, v = 0,45…1,15 м/с).

Řeka Ohře ve světle vědeckých a praktických rybářských aktivit Antonína Friče realizovaných v rámci záchranné akce na zvýšení populace lososa obecného (Salmo salar) v řekách na území Čech v poslední třetině 19. století
Authors: Milotová Nina
Published: March 2023

The present study addresses the previously neglected activities of Professor Dr Antonín Frič (1832–1913) from the Museum of the Kingdom of Bohemia (now the National Museum, Prague), realised for the purposes of fisheries development as part of the protective actions in the 1870s through the 1890s to increase the population of the Atlantic salmon (Salmo salar) in Czech rivers. Primary attention is devoted here to Frič’s interest in the Ohře River and its tributaries, which became a major focus for him in the 1880s. Migration of fish into the Ohře, then faced with significant pollution, had been blocked for over a century thanks to the construction of the fortress in Terezín in 1780–1790. A significant event in this respect was the creation of two fish ladders, then still unique in Bohemia, installed in 1885 and 1887 on the strategic weir below the fortress bridge across the New Ohře. Mention is made of Antonín Frič’s achievements in founding fishing associations (Louny, Karlovy Vary, Žatec) and their mutually enriching cooperation. The text is derived primarily from the research results published by Frič and his colleagues in the journal Vesmír and in book form, as well as the study of Frič’s correspondence (Archive of the National Museum, Literary Archive of the National Literary Monument), historic museum catalogues, and Frič’s personal fisheries collections (zoology department of the Museum of Natural Sciences, National Museum, Prague).

Arterial hypertension is both the cause and the result of the progression of chronic kidney disease, which affects about 10-15% of the population worldwide and the prevalence of which is steadily increasing. As the glomerular filtration rate decreases, the blood pressure level rises respectively. Arterial hypertension (AH) and chronic kidney disease (CKD) are independent and well-known risk factors for the development of cardiovascular diseases, and their combination significantly increases the incidence and mortality from cardiovascular disease. Blood pressure control is the most important factor in slowing the progression of CKD and reducing cardiovascular risk. Currently, there is a place for discussions in the scientific community regarding the target blood pressure levels in patients suffering from CKD. Non-pharmacological methods of treatment can reduce the level of blood pressure in some cases, but do not help to achieve the target values in most of the cases. Patients with hypertension and CKD need combined drug therapy. Certain modern drugs have additional cardio- and nephroprotective properties and should be considered as the first line of therapy. A personalized approach based on evidence-based principles makes it possible to achieve blood pressure control, reducing cardiovascular risk and slowing the progression of CKD. This consensus summarizes the current literature data, as well as highlights the main approaches to the management of patients with hypertension and CKD.

Published: March 2023

Precise interstellar dust extinction laws are important to infer the intrinsic properties of reddened objects and correctly interpret observations. In this work, we attempt to measure the optical–infrared extinction laws of the Large and Small Magellanic Clouds (LMC and SMC) by using red supergiant (RSG) stars and classical Cepheids as extinction tracers. The spectroscopic RSG samples are constructed based on the APOGEE spectral parameters, Gaia astrometric data, and multiband photometry. We establish the effective temperature–intrinsic color relations for RSG stars and determine the color excess ratio (CER) E(λ − G

Authors: Mathur Harsh , Nagaraju K. , Joshi Jayant , de la Cruz Rodríguez Jaime
Published: March 2023

We investigated the diagnostic potential of the Stokes V profile of the Hα line to probe the chromospheric line-of-sight (LOS) magnetic field (B
LOS) by comparing the B
LOS inferred from the weak field approximation (WFA) with that inferred from the multiline inversions of the Caii 8542 Å, Si i 8536 Å, and Fe i 8538 Å lines using the STiC inversion code. Simultaneous spectropolarimetric observations of a pore in the Ca ii 8542 Å and Hα spectral lines obtained from the SPINOR at the Dunn Solar Telescope on 2008 December 4 are used in this study. The WFA was applied on the Stokes I and V profiles of Hα line over three wavelength ranges, viz., around line core (Δλ = ±0.35 Å), line wings (Δλ = [−1.5, −0.6], and [+0.6, +1.5] Å), and full spectral range of the line (Δλ = ± 1.5 Å) to derive the B

BACKGROUND: Sickle cell anemia is a hereditary globin chain condition that leads to hemolysis and persistent organ damage. Chronic hemolytic anemia, severe acute and chronic pain, and end-organ destruction occur throughout the lifespan of sickle cell anemia. SCD is associated with a higher risk of mortality. Genome editing with CRISPR-associated regularly interspersed short palindromic repeats (CRISPR/Cas9) have therapeutic potential for sickle cell anemia thala.
AIM: This research aimed to see if using CRISPR/Cas9 to target β-globin gene is an effective therapeutic and if it has a long-term effect on Sickle Cell Anemia.
METHODS: The method used in this study summarizes the article by looking for keywords that have been determined in the title and abstract. The authors used official guidelines from Science Direct, PubMed, Google Scholar, and Journal Molecular Biology to select full-text articles published within the last decade, prioritizing searches within the past 10 years.
RESULTS: CRISPR/Cas9-mediated genome editing in clinical trials contributes to α-globin gene deletion correcting β-thalassemia through balanced α- and β-globin ratios and inhibiting disease progression.
CONCLUSION: HBB and BCL11A targeting by CRISPR/Cas9 deletion effectively inactivate BCL11A, a repressor of fetal hemoglobin production. However, further research is needed to determine its side effects and safety.

Authors: Maddison David R. , Sproul John S. , Will Kipling
Published: March 2023

A new species of the carabid beetle genus Bembidion Latreille is described from the Central Valley, Los Angeles Basin, and surrounding areas of California. Bembidion brownorumsp. nov. is a distinctive species, a relatively large member of the subgenus Notaphus Dejean, and within Notaphus a member of the B. obtusangulum LeConte species group. It has faint spots on the elytra and a large, convex, rounded prothorax. Of the 22 specimens from 11 localities, all but one were collected more than 55 years ago. Although the collection of the holotype in 2021 at UV light suggest the species is still extant, the lack of other recent specimens suggests the species may have a more restricted distribution than in the past, and its populations may be in decline.
A new deep-sea species of Elliptiolucina Cosel & Bouchet, 2008 (Bivalvia, Lucinida, Lucinidae) from cold seep of the South China Sea
Authors: Jiao Yingyi , Wang Minxiao , Guo Yang , Zhang Junlong
Published: March 2023

The increasing discoveries of new species of the family Lucinidae in the last two decades indicated a surprising diversity of chemosynthetic lucinids in the deep sea, especially in the Indo-West Pacific. However, only a few records have been reported from the South China Sea. A new lucinid species Elliptiolucina subovalissp. nov. is here reported from a deep-sea cold seep site of the South China Sea. The new species is distinct from its congeners by possessing a strong anterior lateral tooth on the right valve and anterior tapering, subrectangular-oval shells. Sequences of three genes (18S rRNA, 28S rRNA, and CytB) were used to analyze its relationships with other species in the subfamily Myrteinae and confirm its taxonomic placement. The result supports the monophyly of Myrteinae but also demonstrates the polyphyly of Elliptiolucina. The new species has a close relationship with E. williamsae and Rostrilucina garuda, but is not closely related to congener E. ingens. By comparing morphological characters, we suggest that E. ingens should not belong to the genus Elliptiolucina. The basal two of three deep-sea clades recognized in Myrteinae may indicate the deep-sea origin of this subfamily. Our results add to the known diversity of deep-sea lucinids and molecular information for poorly studied Myrteinae and highlight the necessity of further investigation on deep-sea lucinids of the South China Sea.

Authors: Mohamed Boussif , Mnassri Aymen
Published: March 2023

Data encryption is one of the security solutions used to protect secret data. The use of image encryption techniques in DICOM (digital imaging and communications in medicine) data to secure it in unprotected networks or storage is the focus of this chapter. Therefore, based on the improvement of a 3D (three dimension) s-box proposed previously, the authors provide a novel efficient images encryption method for medical imaging. The technique also encrypts the DICOM tags and Jpeg compressed DICOM imaging because 512-bit-based blocks of data are processed. A function named encrypt_block() is used for the diffusion and confusion. This function processes a block with subblocks each of 8-bit. For each subblock it uses the s-box for data transformation. The cryptanalysis of the proposed encryption system shows its strength and security. The runtime and the speed of the algorithm demonstrate its low time complexity, which makes it suitable for much electronics hardware, especially embedded systems.
A New Efficient Crypto-Watermarking Method for Medical Images Security Based on Encrypted EPR Embedding in Its DICOM Imaging

Published: March 2023

Digitalization of media has exploded in recent years. It has resulted in the rise of private data hacking, which has been increased by the growth of the data exchange system, i.e., the Internet, as well as the simple access to storage media. New approaches, such as watermarking in (C. Iwendi et al., 2020; D. Datta et al, 2021; Randhir Kumar et al,2021), are being used to combat these hackers. The application of image watermarking technologies to medical images, as proposed in (Nazari, M., et al, 2021; Thanki, R, 2021; Manoj K., 2020), is the focus of this research. In this chapter, we propose a new robust blind crypto-watermarking solution for medical imaging or DICOM file (Digital Imaging and Communications in Medicine) security based on masking (or hide) electronic patient information (patient name, patient ID, patient age...) in its medical imaging, then, erases them from the tag of the DICOM. Before being included into medical imaging, DICOM patient information, or EPR, is encrypted using a modified AES (Advanced Encryption Standard) encryption technique. The image is broken into 8x8 pixel chunks. In each block, we use the 2D-LWT (Lifting wavelet transform), 2D-DCT (discrete cosine transforms), and SVD (singular value decomposition) to insert one bit of the encrypted watermark into the hybrid transform domain. Various attacks, such as noise, filtering, scaling, and compression, are used to test the method. According to the obtained results the watermark (EPR) is imperceptible in the imaging, and the suggested technique has passed the attacks test with success.

Published: March 2023

Identification of system is one of the most important steps in industrial process automation studies. The modeling of a process aims to establish a representation linking the variables of the process, either from an approach of understanding the phenomena involved or from a mathematical processing of the data collected on the process. The object of identification is to estimate the parameters of the models thus obtained. In this chapter, the convergence of a prediction error method applied for the identification of multivariable delayed systems is proven. Indeed, a multivariable system with multiple time delays is used. Then a convergence study is given. A numerical example based on a thermostatic mixing valves process is finally introduced to prove the robustness of the proposed scheme.

Authors: Tang Valerie , Lam H. Y.
Published: March 2023

The aging problem has become a global issue, which is driving an increasing demand for long-term care services for the elderly. Care planning, as an essential support to ensure a high standard of safe and responsive care, is therefore drawing attention from academia and health care providers. To handle the increasing care service demand and enhance the care service quality, a support model in care planning is needed to handle episodic visits, to integrate the care plan with all of the relevant data, and to allow all stakeholders to view and contribute to. In this study, the above described supporting model is formulated through a blockchain-internet of things (BIoT) based care planning analytics model (BCPAM). Embedding blockchain into IoT allows collecting patient's data in real time and decentralizing such data in the nursing home network to achieve effective care planning. In addition, such information is further utilized for healthcare analysis to predict the long-term needs of the elderly.

Published: March 2023

In the customer-oriented enterprise environment, data mining business intelligence (BI) performs key functions that enable business organizations to determine investment risks and estimate returns on investment. It aids in evaluating the gathered information and presenting them in an understandable and practical design that promote data mining analytics. In the current study, banking and retail services were viewed among the rapidly developing technological industry that maintains significant amounts of electronic data. On the account that fraudsters constantly come up with new schemes and refine their existing schemes so they may avoid being easily identified, it is challenging to identify fraud and prevent it from happening. In order to monitor activities relating to fraud prevention, fraud detection, customer retention, business risk management, investment performance, and improving customer satisfaction, the chapter analyzed an artificial neural network machine learning algorithm in data mining techniques and its applications in the retail sector towards service reliability.

Authors: Šporčić Berislav , Glavak-Tkalić Renata
Published: March 2023

The aim of this study was to explore the moderating role of psychosocial well-being in the relationship between gaming motivation and problematic gaming among problematic and recreational online gamers. Data from 511 online video game players (M = 24.89, SD = 6.39) were analyzed. Problematic online gaming was positively correlated with social anxiety, loneliness, and stress, as well as with social escape, competition, coping, skill development, and fantasy motives for playing online video games. Negative correlation was found between problematic gaming and life satisfaction. The results showed significant interaction terms between loneliness and social motive, life satisfaction and recreation and coping motive, and stress and fantasy motive among problematic gamers. Furthermore, results showed a significant interaction term between stress and skill development motive among recreational gamers. The results are discussed in the framework of the compensatory internet use model (Kardefelt-Winther, 2014a).

Authors: Malkanthi S. N. , Dharmaratne P. D. , Galabada G. H.
Published: March 2023

The inherent nature of construction projects is long duration and high cost. Extended project duration leads to escalation of cost. If the project duration is too long, the initial estimation may not be sufficient to recover the actual cost of the contract. To address this problem, Construction Industry Development Authority (CIDA) has introduced a price adjustment method called the “ICTAD formula method for adjustments to contract price due to fluctuation in prices”. Contract documents related to construction projects also provide some provisions to address the issues with material price fluctuations. This study investigated the practices of contractors to minimize the effect of price variation and support of price fluctuation clauses to minimize the impact of price variation. A questionnaire survey was conducted among the professionals to represent CS2 to C5 grade construction companies registered at CIDA. The questionnaire consisted of practices of contractors to minimize the effect of price variation and the impact of using price fluctuation clauses in different aspects. Collected responses were converted to a quantitative value using the relative importance index (RII). In addition, SPSS software was used for the critical review of responses. The results revealed that contractors mostly agree with using price fluctuation clauses to recover the increased project cost due to increased construction input prices. Further, results are evident that using price fluctuation clauses helps to fair risk sharing between the contractor and the client.

Published: March 2023

Context

Athletic trainers (ATs) inconsistently apply rehabilitation-oriented assessments (ROASTs) when deciding return-to-activity readiness for patients with an ankle sprain. Facilitators and barriers that are most influential to ATs’ assessment selection remain unknown.

Objective

To examine facilitators of and barriers to ATs’ selection of outcome assessments when determining return-to-activity readiness for patients with an ankle sprain.

Design

Cross-sectional study.

Setting

Online survey.

Patients or Other Participants

We sent an online survey to 10 000 clinically practicing ATs. The survey was accessed by 676 individuals, of whom 574 submitted responses (85% completion rate), and 541 respondents met the inclusion criteria.

Main Outcome Measure(s)

The survey was designed to explore facilitators and barriers influencing ATs’ selection of pain; ankle-joint swelling, range of motion, arthrokinematics, and strength; balance; gait; functional capacity; physical activity level; and patient-reported outcome assessments when making return-to-activity decisions for patients after an ankle sprain. The survey asked for reasons that participants chose to use or not use each measure (eg, previous education, personal comfort, most appropriate, available or feasible, perceived value, and other). The survey contained 12 demographic items that characterized the sample of respondents and were examined as potential influences on the facilitators and barriers. Chi-square analysis was used to identify relationships among participant demographics and facilitators of or barriers to assessment selection.

Results

Selection of each ROAST and non-ROAST was most commonly facilitated by previous education, availability or feasibility, or perceived value. Avoidance of each ROAST was most often caused by the lack of previous education, availability or feasibility, or perceived value. The presence of facilitators and barriers was affected by various demographic variables.

Conclusions

A variety of facilitators and barriers affected ATs’ implementation of expert-recommended assessments when determining return-to-activity readiness in patients with an ankle sprain. Some subpopulations of ATs experienced more favorable or prohibitive conditions for assessment use.

Authors: Sinharay Angana , Srivastava Smiti R. , Ganguly Purban , Ayub Asif , Bhunia Jit , Ghosh Asim K.
Published: March 2023

Background:

Higher incidence of ill health among the nurses may jeopardize the performance of any hospital. Irony of the situation is that despite being at the center of the healthcare delivery apparatus, there is a strong element of neglect about the health issues of the nursing community.

Objectives:

This study aims to observe and analyze the pattern of ophthalmological morbidity among nursing care personnel in a tertiary care hospital in eastern India.

Materials and Methods:

Five hundred and thirty nursing personnel at the tertiary care hospital underwent comprehensive ophthalmological examination and as and when required underwent ophthalmic investigations after eliciting proper history.

Results:

The mean age of the study population was 48.6 ± 0.8 years. The majority (86%) had mild or no visual impairment (P < 0.00, χ
2: 51.8). The uncorrected refractive error was found to be the common cause of visual impairment (51%) among the study population. About 80% of the study population having visual impairment had reversible causes (P < 0.00, χ
2: 37); 87% of the study population with visual impairment were not aware of their visual condition (P < 0.00, χ
2: 54.8). Around 78% of the study population had not undergone comprehensive ophthalmological examination in the last 12 months (P < 0.00, χ
2: 31.4).

Conclusion:

Regular comprehensive ophthalmological examination and necessary intervention can lead to prevention of visual impairment among the nursing personnel. This is essential for providing, maintaining, and escalating the level of patient care delivery in any tertiary care hospital.
