Authors: Ferrer Osmin , Guerra José , Reyes Alberto
Published: May 2022

In this paper we study a multiparametric nonlinear system with a transcritical bifurcation in a region of points of $ \mathbb{R}^3 $. The parametric regions that constitute the boundaries where important qualitative changes occur in the dynamics of the system are determined. The equilibrium points in each of the regions are also established and classified. Finally, the stability of the equilibrium points at infinity of the system obtained from the Poincare compactification is classified, and the global phase portrait of the system is made.

Authors: Bourkoukou Outmane , El Bachari Essaid
Published: May 2022

E-learning is increasingly gaining popularity in organizational and institutional learning for its several benefits to learn anywhere, anytime, and anyplace. Therefore, explosive growth of E-learning has caused difficulty of locating appropriate learning activities for learner in this context, and it becomes relatively widespread learning method for learner. Several research in e-learning mainly focused on improving learner achievements based on recommendation technique. An ideal recommender system in e-learning environment should be built with both accurate and learning goals. To address this challenge, we propose a recommendation method based on machine learning technique. Based on this tool, a learning approach is designed to achieve personalized learning experiences by selecting the most appropriate learning activities. Moreover, some experiments were conducted to evaluate the performance of our approach. The results demonstrate that our method outperforms other state-of-the-art methods and reveals suitability of using recommender system in order to support online learning activities to enhance learning.

Published: May 2022

Through the network teaching platform, distance teaching provides relevant distance technical support services for adult education, and evaluates teaching results of the teaching method, relying on modern network technology and integrating educational resources. It has become a consistent pursuit in the field of education to change the learning mode of distance learners, to cultivate higher-order sustained thinking ability, and to promote sustained learning so that learners’ knowledge transferability becomes more obvious. The results show that Cronbach’s á coefficient and KMO values of the questionnaire are 0.879 and 0.850, indicating that the reliability and validity of the questionnaire are good. Sustained learning, which consists of learning engagement, learning motivation and learning strategy, can significantly improve knowledge transferability. Distance learning duration and age of learners have significant differences in knowledge transferability. Gender and specialty have no significant difference in knowledge transferability. Conclusions have very important reference value for improving sustained learning effect of learners in distance teaching, promoting the occurrence of learners’ multiple interaction behaviors in distance teaching, and realizing cooperative knowledge construction of learners in distance teaching.
A Blind Video Copyright Protection Technique in Maximum and Minimum Energy Frames Based on The Fast Walsh Hadamard Transform (FWHT) and Discrete Wavelet Transform (DWT) and Arnold Map
Authors: Resen Mohammed S. , Laftah Muna M.
Published: May 2022

Video copyright protection is the most generally acknowledged method of preventing data piracy. This paper proposes a blind video copyright protection technique based on the Fast Walsh Hadamard Transform (FWHT), Discrete Wavelet Transform (DWT), and Arnold Map. The proposed method chooses only frames with maximum and minimum energy features to host the watermark. It also exploits the advantages of both the fast Walsh Hadamard transform (FWHT) and discrete wavelet transforms (DWT) for watermark embedding. The Arnold map encrypts watermarks before the embedding process and decrypts watermarks after extraction. The results show that the proposed method can achieve a fast embedding time, good transparency, and robustness against various attacks.

Election is a basic democratic tool that offers an official mechanism for the people to express their opinions in order to form a government by democratic means. Electronic voting has evolved into the most significant application of e-governance and e-democracy. Few countries have recently taken the opportunity to test and use electronic voting systems. Also, many countries expect that internet voting will become a reality during the next decade. In the conventional voting system, the electors authenticate themselves by displaying credentials; this move is open to the public and is validated by poll workers. During this authentication, they are manually checked before being eligible to vote. The standard system of voting is more costly and needs more human capital. Because of these factors, the whole world is heading toward the trend of e-voting. Electronic voting devices are supposed to be the answer to the shortages. A secure e-voting system must meet many criteria, including uniqueness, performance, fairness, stability, safety, authentication, and anonymity. Blockchain is a modern security solution, which is capable of securing e-voting system. Blockchain is distributed ledger. Each block contains only one transaction. Block chain provides security using cryptography and hashing. Blockchain provides a perfect infrastructure to provide secure e-voting netwms.ork. Blockchain along with smart contracts need hour to improvise an e-voting system. This paper presents a secure blockchain based framework for an e-electronic voting in Iraq.
Face Image Animation with Adversarial Learning and Motion Transfer
Authors: Karim Abdulamir A. , Saleh Suha Mohammed
Published: May 2022

Significant advances have been made in facial image animation from a single image. Nonetheless, generating convincing facial feature movements remains a complex challenge in computer graphics. The purpose of this study is to develop an efficient and effective approach for transferring motion from a source video to a single facial image by governing the position and expression of the face in the video to generate a new video imitating the source image. Compared to prior methods that focus solely on manipulating facial expressions, this model has been trained to distinguish the moving foreground from the background image and to create motions such as facial rotation and translation as well as small local motions such as gaze shift. The pro-posed technique uses generative adversarial networks GANs with a motion transfer model. The network forecasts photo-realistic video frames for a given target image using synthetic input in renderings from a parametric face model. The authenticity in this postprocessing conversion is attained by precise image manipulation. Thorough adversarial training is used to produce greater accuracy in this postprocessing conver-sion. Although more improvements to face landmark identification on videos and face super-resolution techniques have been made to improve the results, the pro-posed technique can provide more coherent videos with improved visual quality, resulting in more aligned landmark sequences for training. In addition, experiments indicate that we obtain superior results compared to those obtained by the state-of-the-art image-driven technique with PSNR 30.74 and SSIM 0.90

Published: May 2022

Dark web is a canopy concept that denotes any kind of illicit activities carried out by anonymous persons or organizations, thereby making it difficult to trace. The illicit content on the dark web is constantly updated and changed. The collection and classification of such illegal activities are challenging tasks, as they are difficult and time-consuming. This problem has in recent times emerged as an issue that requires quick attention from both the industry and academia. To this end, efforts have been made in this article a crawler that is capable of collecting dark web pages, cleaning them, and saving them in a document database, is proposed. The crawler carries out an automatic classification of the gathered web pages into five classes. The classifiers used in classifying the pages include Linear Support Vector Classifier (SVC), Naïve Bayes (NB), and Document Frequency (TF-IDF). The experimental results revealed that an accuracy rate of 92% and 81% were achieved by SVC and NB, respectively.

Published: May 2022

NineMetarhizium anisopliae(Hypocreales: Clavicipitaceae) isolates were evaluated for efficacy againstMelolontha melolontha(Coleoptera: Scarabaeidae) larvae, stability in culture, and the superior isolate used to produce an oil-in-water mycoinsecticide. The phenotypic and genotypic characters of four isolates with high virulence were evaluated for their stability after repeating 12 cycles ofin vitrosubculture. Repeated subculture did not affect the germination of conidia; however, the morphology of some isolates changed significantly. Three isolates lost their virulence, whereas the KTU-2 isolate remained highly pathogenic. Therefore, KTU-2 was selected as the superior isolate for mycoinsecticide production. After the conidia of KTU-2 were produced by solid-state fermentation using cracked rice as the substrate, the conidia were formulated as an oil-in-water emulsion and its efficacy was assessed. The formulation caused 80% mortality onMe. melolonthalarvae even at the lowest application rate (1 × 105conidia/mL) in pot experiments, and complete mortality was obtained with the concentration of 1 × 107conidia/mL. Lethal concentrations that kill 50% and 95% ofMe. melolonthalarvae present were estimated as 9.29 × 103and 2.1 × 106conidia/mL, respectively. Oil-in-water mycoinsecticide could be a potential candidate for the commercial control ofMe. melolonthaand other white grubs.
Numerical Investigation of Secondary Vortex Structures in a Rotor Wake
Authors: Bodling Andrew , Potsdam Mark
Published: May 2022

In hovering rotor computational fluid dynamics simulations, a common phenomenon is the breakdown of the primary vortex system due to secondary vortices, which are characterized by S-shaped vortical structures appearing between the primary blade-tip vortices. Since the presence of the
secondary vortices is strongly influenced by the numerical settings, the degree to which secondary vortices physically occur warrants investigation. Therefore, this study investigates how the numerical settings affect the development of secondary vortices in hover simulations using the rotating
blade geometry from previous experiments, where the focus is on temporal convergence. The computed near-wake vortical flow field is qualitatively compared to the experimental results. The calculations are then used to elucidate the secondary vortex development process, where it is shown that
the secondary vortices develop by the interaction of the vortex sheet with the primary vortex structure. A number of parametric studies are done on the rotating blade geometry to investigate how the numerical settings affect the secondary vortex development process. Although the focus is on
understanding the impact of temporal convergence, the effect of the off-body grid structure, grid rotation, mesh resolution, numerical dissipation, and time-step scaling is also studied. In contrast to previous work, the resulting wake breakdown from using the different numerical settings
is compared both qualitatively and quantitatively. For relatively high flow solver subiteration convergence, the off-body grid structure and grid rotation have little effect on the development of the secondary vortex structures. However, at low solver subiteration convergence, larger differences
occur between the torus and no torus grid structures. A parametric sweep on subiterations shows that as the subiteration residual drop increases the vortex sheet is broken down less and, correspondingly, both the rotor performance data and peak number of secondary vortices converge. The analysis
shows that when the subiteration convergence or grid resolution is not high enough, the vortex sheet and primary vortex are broken down, which disrupt the development process and leads to fewer secondary vortices. To better understand the rotating blade case, a separate vortex ring study is
done to observe how vortex breakdown is influenced by off-body grid structure and different levels of subiteration convergence. In agreement with the rotating blade case, when all flow solvers are sufficiently converged, vortex breakdown is minimized and the solution to the rotating and stationary
torus is identical.

This is an ecological study analysing spatial patterns of the total mortality over the first 24 hours of life and that due to preventable causes using data from the mortality information system (SIM) and live birth information system (SINASC) based on the municipalities of Pernambuco State, Brazil. The total mortality rates over the first 24 hours and that due to preventable causes were calculated for each municipality for the decades of 2000 to 2009 and for 2010 to 2019 to enable a comparison of the spatial patterns with spatial scan statistic used to identify clusters. Over the first 24 hours of life, a total of 13,571 deaths were reported, out of which 10,476 (77.2%) were preventable. The total mortality rate over the first 24 hours of life decreased from 5.5 in the 2000- 2009 period to 3.7 per 1000 live births in the following decade: a reduction of 32.7%, while the mortality rate due to preventable causes decreased from 4.4 to 2.8 per 1000 live births, a reduction of 36.7%. In the first decade, spatial exploratory analysis found three mortality rate clusters encompassing 56 municipalities over the first 24 hours of life. With respect to preventable causes over the first 24 hours of life, two mortality rate clusters were identified encompassing 41 municipalities. Risk areas for mortality over the first 24 hours of life were detected through spatial scan statistic. This method, directed towards uncovering the geographical distribution of deaths of very premature infants, can act as a tool for identifying priority areas to guide healthcare interventions.
Bayesian spatial modelling of contraception effects on fertility in Mexican municipalities in 2020
Authors: Núñez Medina Gerardo
Published: May 2022

The prevalence and use of contraceptive methods is an essential element to explain the behaviour of fertility and population growth. The objective of this study was to analyse the spatial correlation between the use of contraceptive methods in women of childbearing age and fertility levels observed in Mexico’s municipalities in 2020. Data on contraceptive use are from the National Survey of Demographic Dynamics (ENADID) 2018, while fertility rates were estimated from vital statistics and population census data. Three Bayesian spatial models including fixed effects, random effects and spatial effects were employed. The models were estimated using the integral nested Laplace approximation (INLA) package available in the R language. The results reveal the existence of important regional inequalities associated with the use and prevalence of contraceptive methods, which generate marked differences in observed levels of fertility between municipalities.
Asymptotic stability of small ground states for NLS under random perturbations
Authors: Camps Nicolas
Published: May 2022

We consider the cubic Schrödinger (NLS) equation on the Euclidean space perturbed by a short-range potential

V

. The presence of a negative simple eigenvalue for

-\Delta+V

gives rise to a curve of small and localized nonlinear ground states that yield some time-periodic solutions known to be asymptotically stable in the energy space. We study the persistence of these coherent states under rough perturbations. We shall construct a large measure set of small scaling-supercritical solutions below the energy space that display some asymptotic stability behaviors. The main difficulty is the need to handle the interactions of localized and dispersive terms in the modulation equations. To do so, we use a
critical-weighted strategy
to combine probabilistic nonlinear estimates in critical spaces based on

U^p

,

V^q

(controlling higher-order terms) with some local energy decay estimates (controlling lower-order terms). We also revisit in the perturbed setting the analysis of Bényi, Oh,
and Pocovnicu (2015) on the probabilistic global well-posedness and scattering for small supercritical initial data. We use a distorted Fourier transform and semiclassical functional calculus to generalize probabilistic and bilinear Strichartz estimates.
Interacting helical traveling waves for the Gross–Pitaevskii equation
Authors: Dávila Juan , del Pino Manuel , Medina Maria , Rodiac Rémy
Published: May 2022

We consider the three-dimensional Gross–Pitaevskii equation

i\partial_t \psi +\Delta \psi+(1-|\psi|^2)\psi=0\quad \text{for $\psi\colon\mathbb{R}\times \mathbb{R}^3 \rightarrow \mathbb{C}$}

and construct traveling wave solutions to this equation. These are solutions of the form

\psi(t,x)=u(x_1,x_2,x_3-Ct)

with a velocity

C

of order

\varepsilon\lvert\log\varepsilon\rvert

for a small parameter

\varepsilon>0

. We build two different types of solutions. For the first type, the functions

u

have a zero-set (vortex set) close to a union of

n

helices for

n\geq 2

and near these helices

u

has degree

1

. For the second type, the functions

u

have a vortex filament of degree

-1

near the vertical axis

e_3

and

n\geq 4

vortex filaments of degree

+1

near helices whose axis is

e_3

. In both cases the helices are at a distance of order

1/(\varepsilon\sqrt{\lvert\log\varepsilon\rvert})

from the axis and are solutions to the Klein–Majda–Damodaran system, supposed to describe the evolution of nearly parallel vortex filaments in ideal fluids. Analogous solutions have been constructed recently by the authors for the stationary Gross–Pitaevskii equation, namely the Ginzburg–Landau equation. To prove the existence of these solutions we use the Lyapunov–Schmidt method and a subtle separation between even and odd Fourier modes of the error of a suitable approximation.

In this study, the response of atmospheric electrical and meteorological variables at three different sites of Argentina are studied during the total solar eclipse of December 14, 2020: Valcheta (100% darkening), Buenos Aires (73%) and El Leoncito (71%). The reduction insolar irradiance caused by the solar eclipse was expected to directly affect the near-surface electric field, known as the potential gradient (PG), through a reduction in turbulence and an increase in air conductivity. From the analysis of the observed meteorologicalparameters (temperature, relative humidity, and wind), no effects on the PG were observed that can be unequivocally attributed to this event based solely on boundary layer dynamics. The prevailing synoptic situation altered the response that the boundary layer could have given, namely, a clear drop in radiation, particularly at Valcheta, which was very close to a frontal zone and had occasional cloud coverage and reports of atmospheric suspended dust. PG measurements at Valcheta during the eclipse showed PG values several ordersof magnitude higher and of opposite sign to the global daily mean fair weather (FW) PG curve and the local FW-PG curves calculated at CITEDEF (940 km away) and CASLEO (1200 km away). The PG values at Valcheta were shown to be more closely related to disturbed weather conditions than FW. On the contrary, at the other two locations studied, CITEDEF and CASLEO, further north and more distant from the frontal zone, the observed PG values on the day of the eclipse showed a higher consistency with the local daily mean FW-PG curves. A comparison between the FW-PG local curves at these two sites and the evolution of PG during the day of the eclipse, however, reveals a drop in PG values during the eclipse.
CAPTURING THE FLUCTUATIONS OF SOME ALGERIAN MACROECONOMIC VARIABLES USING NEW KEYNESIAN MODEL FOR SMALL OPEN ECONOMY FOR THE PERIOD 2000-2018: A BVAR-DSGE APPROACH
Authors: Khouiled Ibrahim , Sellami Ahmed
Published: May 2022

In this study, we estimated and simulated an NKDSGE model for Algeria based on the method through which a small open economy should react to economic. The model consists of hybrid equations for the IS curve, Phillips curve, exchange rate equation and monetary policy based on Taylor's type. We estimated the system of equations by the BVAR technique on quarterly Algerian macroeconomic data from 2000 to 2018. We have then used the estimated parameter values in the simulation to capture the impact of foreign shocks for: inflation, output, technology, trade terms and monetary policy on the Algerian macroeconomic. The results confirmed that all foreign shocks contributed to the fluctuations of domestic GDP, domestic inflation and exchange rate through simultaneous economic cycles between 2-4 years except the worldwide output shock, which lasted about 10 years. The monetary rule appeared to play its role each time with a faithful memory of the historical interest rate without giving much weight to the exchange rate, domestic output and inflation.

Although Sign Language is one of the classical and most natural means of communication, most people are unaware of it, and interpreters are less in number. The aim of this paper is to develop an interface between dumb/deaf and the normal people. Motivation behind this is to introduce an application that will not only facilitate users to learn sign language but also will help them to convert the hand sign gestures to corresponding alphabets or numbers. The system will also help to convert text to hand sign gestures. This paper contributes an approach for users to communicate with dumb and deaf individuals effectively and efficiently by removing the need of translation facility. Convolution Neural Networks (CNN) is used in translating the hand sign gestures to text. Natural Language Processing (NLP) helps in converting given input text to their corresponding hand sign gestures.
Rumi’s Ontology: The Being and the World
Authors: Zamani Alavijeh Hossein , Asadi Amjad Fazel
Published: May 2022

The present article aims to explore Rumi’s ontological approach to Being and World which is deeply impressed by mystical doctrines and practices of Islamic Sufism and the writings of his contemporary Islamic philosopher Ibn 'Arabi. Rumi finds all the components of creation as a manifestation of the unique manifestations of God, in which God has manifested as much as the talents of the creators. In Rumi's view, existence is a mirror in which God is constantly manifesting. Rumi finds all the components of the universe full of meaning and considers meaning as God. He calls on people in this field to read the meanings of different and diverse manifestations of existence with the foresight of the mind and inner purity. Although the question of Being was basically addressed in Heidegger’s seminal Being and Time, many questions and paradoxes were left unanswered and unresolved for him and his successors regarding the subject of Being. Despite Heidegger’s harsh onslaught on the pillars of western metaphysics, his Being and Time was more concerned with posing questions regarding the subject of Being rather than offering answers.   The present paper by delineating Rumi’s ontological approach aims to broaden our horizons in the field of existential philosophy and offer a new and advanced perspective on dealing with the question of Being.

WEB-BASED RADIOTHERAPY INCIDENT ANALYSIS SYSTEM
Authors: Addison Eric Clement Desmond Kotei , Yankson Ruth , Ngoah Amos
Published: May 2022

Objective: A web-based radiotherapy incident analysis system was developed and tested for safer radiotherapy implementation. Radiation dose incidence reporting is a known evaluation method for learning from the errors that occur during the radiotherapy procedure. Established as a safety-critical, non-punitive, just-culture system, the waterfall model was employed in the construction process of the system to identify and learn from incidents, non - conformance, and near-misses in radiotherapy settings.
Method: The theoretical framework of the thesis was based on the Systems-Theoretic Accident Model and Processes (STAMP).  The system algorithms were designed to identify sixty-two (62) radiotherapy errors.
Results: The results of system implementation require patient test data that was selected based on the PRISMA 2009 method. Records identified through the radiotherapy manual database were 4479 patient data set.  The system reported 1215 treatment sessional errors which are equivalent to 219 patient errors when analyzed with simple descriptive statistics. Incident data were identified directly by the system, in terms of incident level, form and patient incident, year dependent, site-specific, primary site incident, and treatment status. Frequency of error types were 10% incidents, 85% non-conformance and 5% near-misses. Patient error types identified 58.447% incidents, 13.699% non-conformance and 27.854% near-misses.
Conclusion and Recommendation: Treatment status gave an overview of the quality of clinical decisions and implementation in the management of the patient. In future iterations, error tagging and solution recommendation parts with supervised machine learning algorithms would be made available to show the types of errors captured and chances of mitigating risks in terms of percentages for incident learning.

Published: May 2022

Workaround in the hospital setting acts as a dichotomous trope. These behaviours entitle, yet compromise the quality care to the patients. These behaviours provide and hide information about medical team members’ work. Workarounds can be individual or collective. As nurses make the majority of the health care workforce, it is essential to understand the use of workarounds in this group. Analysing and understanding the nurses’ practice and their perception of workaround behaviours is central to improving quality patient care at the bedside, where care is delivered to the patients. To exhaust the negative and tackle the positive potential of workarounds in hospitals, the management must acknowledge the factors that in uence implementation and proliferation of workarounds and the role of local and organisational culture in resolving these behaviours.

Hence an attempt was made to study the effectiveness of music therapy on the level of stress among patients undergoing haemodialysis at Rajarajeshwari Medical College & Hospital, Bangalore. The study was conducted on 10 haemodialysis patients who were admitted in the Dialysis Unit and available at the time of the study and were selected by purposive sampling method. Patients were analysed by using Stress rating scale checklist before and after music therapy that was given for 1 hour. The results showed signi cant difference in the pre-therapy to post-therapy score favouring a decrease in the level of stress (p=0.05). The study revealed no association between post-test level of stress with gender and religion. However, there was an association between post-test level of stress and age, occupational status, educational status, income and marital status. The study clearly showed a need for providing music therapy to the patients undergoing haemodialysis for reducing their stress

In wound dressing procedures, if wound contamination is limited, there is a less chance of infection. A recent survey in India estimated the prevalence rate of chronic wounds at 4.5 per 1000 population. In this study the practice of wound dressing technique among staff nurses before and after planned demonstration was evaluated and the association of the practice scores of wound dressing with selected demographic variables was found. A quasi experimental one group pre-test post-test design was adapted. The population comprised of staff nurses working in the medical and surgical wards in IKDRC-ITS hospitals in Ahmedabad. Convenient sampling technique was used to select 60 staff nurses. A structured observational checklist consisting of 20 items evaluated the effectiveness of planned demonstration on dressing technique. The data collected was analysed by using descriptive and inferential statistics. Study revealed that in pre-test majority (81%) of the staff nurses had a poor practice and in post-test, all (100%) had good practice on wound dressing. The mean post-test (15.6), practice scores were higher than pre-test practice score (9.9); the calculated t value (19.56) was greater than table value (t=2.00) at 0.05 level of signi cance. There was a signi cant association of experience with pre-test practice scores while no signi cant association was found between age, gender and education with pre-test practice scores. Also there was no signi cant association between selected demographic variable in post-test practice scores. The study proved that the planned demonstration on wound dressing was an effective measure to improve the practice level of staff nurses.

Prevention of Deep Vein Thrombosis among Patients Having Undergone Neurosurgery: A Systematic Review
Authors: SD Shani
Published: May 2022

Deep vein thrombosis (DVT) and pulmonary thromboembolism are high in the setting of neurosurgery causing significant mortality and morbidity. Incidence of venous thromboem- bolism among neurosurgery patients is very high (approximately 23%) in the absence of prophylaxis. There is no consensus among surgeons regarding. A systematic review following preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines for design, conduct and reporting was conducted to find out the evidences for DVT prophylaxis among neurosurgery patients and to develop an evidence-based protocol for prevention of DVT. Eligibility criteria was to include studies done among adult patients who had undergone craniotomies or spinal cord. Data were summarized in a pre-defined data extraction form. Summarized information on study characteristics such as design and year, author information, sample size, prophylactic method used, outcome, side effects, investigations done and the timing of prophylactic method used. Risk of bias for randomised controlled trials (RCT) were assessed using predefined Cochrane risk of bias tool. Observational studies were assessed for risk of random and systematic bias. All the studies except one are having high risk of bias. The total participants of included studies were 2811. The incidence of symptomatic DVT ranged from 0.01-0.6 percent. Asymptomatic DVT incidence ranged from 4-29.4 percent. The prophylactic methods used were pneumatic compression devices, low molecular weight heparin (LMWH), nadroparin, venacaval filter, elastic compression stockings and physiotherapy. There was no significant difference between the chemo prophylactic and mechanical prophylactic group. Chemoprophylaxis was used post-operatively after 12 hours to 5-6 days. The pneumatic compression device and elastic crepe bandage were used peri-operatively. The incidence of post-operative bleeding and hematoma with the use of LMWH and nadroparin was 0.4 to 1.8 percent, which is within the limits of usual post-operative risk of bleeding. The use of compression device was associated with minor skin irritations. These findings suggest that pharmacological and mechanical prophylaxis can be combined to prevent DVT among neurosurgery patients without increased bleeding risk or discomfort.
