Ideas about volunteering among modern youth
Authors: Molchanov Sergey V. , Almazova Olga V. , Poskrebysheva Natalia N.
Published: June 2021

Background. Currently, there is an increase in the popularity of the volunteer movement among young people. The motivational basis of volunteer activity plays an important role in the analysis of the level of volunteer involvement, readiness for constant participation in helping behavior. Objective of the research: studying the characteristics of motivation among young people to participate in volunteering as well as analyzing the ideas about digital volunteering. Design. The study involved 47 full-time studentsof Moscow colleges 18 to 23 years old (M = 20.1, SD = 2.3). We used a questionnaire for analyzing volunteering motivation(VFI). The questionnaire aimed at studying the volunteer activity of respondents and understanding the content of volunteer activity in different areas wasused as well as a diagnostic tool. The VFI questionnaire was usedfor the first time in a Russian sample. The translation was done independently by three experts. Aftercoordinating theirversions, a reverse translation was made into the original language, followed by a comparison of the original version with the resulting double translation. Results. The results obtained made it possible to identify 3 groups of motivational preferences in the field of volunteering for young people. The group of “active volunteers” is characterized by a high significance of most of the possible motives for helping behavior. The largest group in terms of number was the group of “pragmatists” volunteers focused on “volunteering as a career opportunity” and “volunteering as a source of development”. A group with a low level of understanding of possible options for volunteer activity was also identified — a group of “passive volunteers”. The nature of the relationship between real behavior and awareness of motivation can be two-way — on the one hand, the presence of motivation can stimulate participation in volunteering, and on the other hand, the experience of participation can help reflect the personal meaning of the process for oneself. The living experience of helping behavior determines the emphasis on “the absence of live direct interaction” as a lack of digital volunteering, especially among active volunteers and pragmatic volunteers. A certain inconsistency in ideas about the merits and limitations of digital volunteering was revealed — from assessing the capabilities of the digital form as broader, to assessing the space of self-realization in the distant online form as much narrower than in the offline form. Conclusions. The priority types of motivation are highlighted. Volunteering allows you to realize value attitudes, and is also viewed as a source of competence development. At the same time, the use of volunteer activity as a way to protect and compensate for psychological experiences is the least in demand. The concept of digital volunteering is rather vague — general characteristics of the distant form of helping behavior are indicated with a pronounced low level of awareness of volunteer structures in the Internet.

Background. Neuropsychological diagnostics and rehabilitation are among the fundamental practical tasks facing a clinical psychologist. Today, rehabilitation goes beyond the usual framework in which it was 40–50 years ago. The course of the disease, stressful influences radically change the physical, psychological and social functioning of a person. It is the functioning of a person (and not the state of his functions) in new, often limiting living conditions that becomes an object in the modern rehabilitation system, which is a joint activity of the patient, his relatives and specialists of the multidisciplinary rehabilitation team. Objective: analysis and generalization of the diagnostic and rehabilitation experience accumulated in neuropsychological rehabilitation;identification of quality criteria for neuropsychological diagnostics and rehabilitation of patients with memory impairments in case of brain damage, which should be followed by a practicing psychologist in the process of rehabilitation work. Results. Based on the analysis of applied research and practical guidelines, the recommended diagnostic tools for detecting memory impairments are presentedand the main directions and effective methods of rehabilitation work in amnestic syndrome are highlighted. It is shown that different degrees of severity of a amnestic defect requires the choice of an appropriate direction of work in the process of neuropsychological rehabilitation: the formation of new mnestic means; the organization of “suggestive and reminiscent” environments and new strategies for behavior in this environment; general (non-specific) principles of restorative learning. Conclusions. The presented material can serve as a “support” in the practical work of a clinical psychologist with patients with memory impairments and brain lesions.The text outlines the main directions of diagnostic and rehabilitation work which a practicing psychologist must be aware of.
Discourses of Childism: How covid-19 Has Unveiled Prejudice, Discrimination and Social Injustice against Children in the Everyday
Authors: Adami Rebecca , Dineen Katy
Published: June 2021

Do children suffer from discriminatory structures in society and how can issues of social injustice against children be conceptualised and studied? The conceptual frame of childism is examined through everyday expressions in the aftermath of policies affecting children in Sweden, the UK and Ireland to develop knowledge of age-based and intersectional discrimination against children. While experiences in Sweden seem to indicate that young children rarely suffer severe symptoms from covid-19, or constitute a driving force in spreading the virus, policy decisions in the UK and Ireland to close down schools have had detrimental effects on children in terms of child hunger and violence against children. Policy decisions that have prioritised adults at the cost of children have unveiled a structural injustice against children, which is mirrored by individual examples of everyday societal prejudice.
Migrant Workers in Malaysia: covid-19’s Impact on the Rights of their Children and Siblings in Pakistan
Authors: Khoso Abdullah , Noor Ahmad Hilmi Mohamad
Published: June 2021

With the help of narratives of migrant workers in Kuala Lumpur, Malaysia, this article seeks to understands the impacts of the covid-19 (known as the 2019 novel coronavirus) pandemic on the rights of their children and children’s siblings in Pakistan. The pandemic impacted the flow of remittances to their families, which further impacted children’s right to education, livelihoods and food. They also revealed that the pandemic had impacted their children’s right to protection, play and development. Children had lost the freedom to play and go outside, socialise and learn. Migrant workers’ children and siblings with limited financial support should have been provided with adequate financial and social security support by Pakistan, but they were not. They also revealed that during the pandemic, children were also regular victims of harsh treatment and physical abuse by adult family members, reflecting the exacerbation of issues of breaches of their fundamental right to protection and emotional integrity.
“Zooming In” on Children’s Rights During a Pandemic: Technology, Child Justice and covid-19
Authors: Lynch Nessa , Kilkelly Ursula
Published: June 2021

The implementation of public health measures in response to the covid-19 pandemic has impacted heavily on the operation of child justice systems and places of detention, creating new challenges in the safeguarding and implementation of children’s rights. Yet, it has also been a time of innovation, particularly in the use of technology. Using case studies from Ireland and Aotearoa New Zealand, we discuss how technology has been used to maintain the balance between restrictive yet necessary public health measures and the operation of the child justice system. Examples include remote participation in remand hearings and trial and the use of “virtual visits” for children in detention.

Published: June 2021

The Scottish Children’s Hearings System makes life-changing decisions regarding the care and protection of children up to 18 years of age referred due to a need for support – because of offending behaviour or a risk to their physical or emotional safety. In March 2020, due to the covid-19 crisis, Hearings underwent one of the most significant changes since their inception: proceedings shifted to an online conferencing platform (“virtual hearings”), and some procedural modifications were introduced. In June 2020, we used an online survey to gather more than 270 responses from professionals, volunteers, young people, and families who had experience of virtual hearings. These responses highlight that while there are reasonable justifications for the use of virtual hearings, including the duty to ensure orders are appropriately reviewed and renewed, concerns related to children and young people’s right to participation, privacy and representation bring into question the extent to which children’s rights are realised in virtual Children’s Hearings.
The Lightness/Pitch Crossmodal Correspondence Modulates the Rubin Face/Vase Perception
Authors: Zeljko Mick , Grove Philip M. , Kritikos Ada
Published: June 2021

We examine whether crossmodal correspondences (CMCs) modulate perceptual disambiguation by considering the influence of lightness/pitch congruency on the perceptual resolution of the Rubin face/vase (RFV). We randomly paired a black-and-white RFV (black faces and white vase, or vice versa) with either a high or low pitch tone and found that CMC congruency biases the dominant visual percept. The perceptual option that was CMC-congruent with the tone (white/high pitch or black/low pitch) was reported significantly more often than the perceptual option CMC-incongruent with the tone (white/low pitch or black/high pitch). However, the effect was only observed for stimuli presented for longer and not shorter durations suggesting a perceptual effect rather than a response bias, and moreover, we infer an effect on perceptual reversals rather than initial percepts. We found that the CMC congruency effect for longer-duration stimuli only occurred after prior exposure to the stimuli of several minutes, suggesting that the CMC congruency develops over time. These findings extend the observed effects of CMCs from relatively low-level feature-based effects to higher-level object-based perceptual effects (specifically, resolving ambiguity) and demonstrate that an entirely new category of crossmodal factors (CMC congruency) influence perceptual disambiguation in bistability.
“[T]hat Monstrous Machine of his”: The Machine Metaphor in John Cleland’s Memoir of a Woman of Pleasure
Authors: Uttama Choedphong
Published: June 2021

John Cleland’s Memoir of a Woman of Pleasure (1748–49), commonly known as Fanny Hill, is regarded as the first pornographic novel in English literature. Its description of sexual activities is explicit but its language is not coarse. It employs a wide range of metaphors to refer to both sexual acts and genitalia and the metaphor used most frequently to refer to the penis is “the machine.” The machine metaphor will be the focus of this paper, which aims to argue that the machine metaphor carries two meanings. The first is the machine as one of military metaphors common in erotica since sexual acts have long been represented as battles. Female sexual pleasure, portrayed in this novel, depends on the state of being destroyed or conquered by a large machine. The second usage of the military metaphor suggests the strong affiliation between the penis and a hydraulic machine – the hydraulic penis—as this paper will call it. That is, female sexual pleasure is not only entwined with the state of being ruined but also with a fluid flow.
Gender Identification in Language Other than Mother-Tongue: A Case of Non-Thai Listeners Deciphering a Thai Male Speaker’s Gender
Authors: Gadavanij Savitri
Published: June 2021

This paper explores what factors contribute to distinguishing gay sounding and straight man sounding speech; linguistic cognate or social knowledge and whether the gender of listeners also determines ability in identification. To answer these questions, 286 participants were classified by nationality into 3 groups of participants: Thai listeners as a control group, Zhuang, and Other listeners. They were asked to listen to 12 voice stimuli in Thai from straight and gay men and identify the gender of the speakers. The outcome revealed that the accuracy rate in identifying a speaker’s gender varied among the 3 groups of listeners with Thai listeners scoring the highest in gender identification, followed by the Others and Zhuang respectively. This indicates that social knowledge gained from one’s presence Thailand is more important than linguistic cognate. Gender identification may have been made based on the expectation of the ‘typical’ social scene such as the high visibility of gay men in Thailand. The results also suggest that gender of the listeners does not have a significant bearing on the ability to differentiate gay and straight male voices.
The Diffusion of Identity: A Study of Three Contemporary Thai Short Stories through the Lens of Western Narrative Conventions
Authors: Ford Sean
Published: June 2021

Literary works give expression to universal themes through settings, subjects, and techniques that are culturally tied. This article reviews generic conventions involving point of view, protagonist, conflict, rising action, climax, falling action, and resolution that typify Western short stories in order to examine how varying patterns can illuminate cultural contrasts between Thailand and the West. Widely known stories by Katherine Mansfield and Amy Tan serve to exemplify the conventional Western pattern and its versatility and to provide a basis for discovering alternative patterns that characterize numerous contemporary Thai short stories. An analysis of stories by S.E.A. Write award winners Phaitoon Thanya, Anchan, and Ussiri Thammachot through the comparative lens of Western conventions reveals how divergent narrative techniques involving point of view and plot elucidate and corroborate divergent expressions regarding the nature of identity. Narrative patterns in these Thai short stories help produce diffusions of identity that reflect a collectivist ethos and an acceptance of uncertainty and impermanence, while adherence to the Western formula reinforces a core belief in the permanence and persistence of the individual ego over time.
Audience Development in Thai Contemporary Theatre and Dance: A Study of the Barriers to Audience-Building
Authors: Thamkulangkool Piyawat
Published: June 2021

This research article examines the current situation of audiences in Thailand who attend non-mainstream contemporary theatre and dance, focusing on the barriers to building audiences for this type of performance. Mixed methods were used to collect data from various target groups, including qualitative methods like in-depth interviews, and focus groups for contemporary theatre and dance companies and arts spaces, and quantitative data gathered from audience questionnaires and surveys. The study revealed that many theatre and dance companies or groups run by artists often put more emphasis on their performance-making than on their organization or management. Such a production-centered emphasis often neglects the importance of two-way interaction between artists and audiences and shows insufficient appreciation of audiences in developing their performances and programs. The inattention of many performance companies or groups to their current and potential audiences and to techniques to build and develop them is widespread, but not universal. However, a few groups have worked to create and manage their performances based on audiences’ perspectives, thus both removing barriers to performance participation as much as possible and motivating transactional relations with audiences. Audience responses from these companies has led to greater audience engagement and improved audience appreciation.

Published: June 2021

As part of a long-term ecological study of the cryptic comunity of Jamaican coral reefs carried out by Jeremy B.C. Jackson and associates during the 1970s and early 1980s, collections were made of reef bryozoans found at 14 sites around the island. Space occupied by bryozoans on undercoral surfaces is dominated by relatively few species. However, during scanning electrone microscopy study and monograph preparation a diverse assortment of relatively rare species was discovered. Of the 132 species found, 56%, 74 species (70 cheilostomes and 4 cyclostomes) are new, as are one family (Inversiscaphidae) and 5 genera (Planospinella, Caribaria, Spirocoleopora, Gemellitheca, and Palliocella).

Published: June 2021

Objective: This study evaluated the effect of doxofylline combined with penehyclidine hydrochloride on the pulmonary inflammatory response during mechanical ventilation in chronic obstructive pulmonary disease (COPD), as well as to identify the effects of JNK/SAPK signaling pathway
in this inflammatory response. Methods: The COPD model can be constructed by exposing it to cigarette smoke and injections of lipopolysaccharide into the airway. Rats were selected randomly for treatment with doxofylline, penehyclidine hydrochloride, a combination of these two drugs.
The control Group received no drug treatment. The date were processed using ANOVA statistical analysis. Results: In all rats, the lung tissue was pathologically characteristic of COPD. Peak airway pressure, the wet/dry weight of lungs, and degrees of TNF-α, IL-10, malondialdehyde,
JNK, and p-JNK decreased; while IL-10 and superoxide dismutase levels increased (p < 0.05) in all Groups having received drug treatment (p < 0.05) when compared to control. The combination of penehyclidine hydrochloride with doxofylline had a stronger effect on all
of these metrics than either drug alone (p < 0.05). Conclusion: Based on health informatics, This study suggests that the combination of penehyclidine hydrochloride with doxofylline can promote the recovery and maintenance of immune homeostasis in mechanically ventilated COPD
rats, and that the underlying mechanism may be is influenced by downregulation of the JNK/SAPK signaling pathway.
A Novel Disease Diagnosis Method Using Combining Knowledge Graph and Deep Learning
Authors: Cai Xi
Published: June 2021

Disease diagnosis methods based on deep learning have some shortcomings in the auxiliary diagnosis process, such as relying heavily on labeled data and lack of doctor or expert experience knowledge. Based on the above background, this study proposes a disease diagnosis method combining medical knowledge atlas and deep learning (CKGDL). The core of the method is a knowledge-driven convolutional neural network (CNN) model. The structured disease knowledge in the medical knowledge map is obtained through entity link disambiguation and knowledge map embedding and extraction. The disease feature word vector and the corresponding knowledge entity vector in the disease description text are used as the multi-channel input of CNN, and different types of diseases are expressed from the semantic and knowledge levels in the convolution process. Through training and testing on multiple types of disease description text data sets, the experimental results show that the diagnostic performance of this method is better than that of a single CNN model and other disease diagnosis methods. And further verified that this method of joint training of knowledge and data is more suitable for the initial diagnosis of the disease.

Published: June 2021

By exploring different prenatal diagnosis indications of fetal chromosomal abnormalities, it can provide a theoretical basis and reference value for clinical consultation of pregnant women with similar high-risk factors. In this paper, 1800 pregnant women undergoing amniotic fluid aspiration
chromosomal examination in the prenatal diagnosis center were selected as the object of this study. Amniocentesis, fetal cell culture, and karyotype analysis were performed on pregnant women who were 14-20 weeks pregnant and had signed an informed consent. After amniocentesis fetal chromosome
analysis, the type of fetal chromosomal abnormality was determined, and the detection rate of chromosomal abnormality was statistically described. Chi-square test was used for comparison between groups, P < 0.05. This study shows that the use of ultrasound screening combined with
maternal serum indicators is effective in screening fetal structural abnormalities and chromosomal abnormalities in early pregnancy, and significantly improves the detection rate of chromosomal abnormalities. The detection of fetal structural malformations is also very high, but it should
be combined with ultrasound screening of mid-to-late pregnancy. The tricuspid regurgitation and umbilical vein a-wave reversal in the soft ultrasound index can be used as predictors of fetal congenital heart disease in early pregnancy.
Clinical Value of Echocardiographic Parameters in Patients with Chronic Heart Failure
Authors: Liu Tianying , Duan Xin
Published: June 2021

Chronic heart failure (CHF) is a major disease that affects the safety of human life. The traditional diagnosis method of chronic heart failure is mainly blood test. At the same time, the conventional treatment of heart failure is not only limited to improve the clinical symptoms of
patients, but also can prevent the deterioration of chronic diseases. Systemic adjuvant treatment of heart failure also includes improving the quality of life and regulating the mood of patients. However, the traditional diagnostic methods of chronic heart failure have the disadvantages of
incomplete and unreliable diagnostic parameters. Therefore, in view of this situation, this paper will carefully analyze and study the application of ultrasound diagnosis technology in the diagnosis of chronic heart failure, and compare the corresponding diagnostic parameters with conventional
blood detection parameters, including ventricular septal thickness, ventricular septal thickness, ventricular septal thickness, end diastolic ventricular posterior wall thickness, ejection dispersion and maximum blood flow velocity. In the experimental part, 50 related patients in a hospital
were diagnosed and compared. The experimental results show that the ultrasonic diagnosis technology can reflect the heart function of patients with heart failure more comprehensively and reliably.

Authors: Shi Shanhong , Xing Fang , Lin Weiyuan
Published: June 2021

Objective: This paper focuses on the foot-process in renal biopsies of patients with lgA, and examines their correlation with baseline clinical indicators and pathological manifestations in patients with lgA. Method: A retrospective data of patients who performed renal
biopsy proven IgA nephropathy was selected. The patients who reached the agreed standard were grouped based on the degree of foot-process. There were three groups (ABC Groups) (Du, Y. and Huang, C, 2009. The value of proteinuria and foot process fusion in the onset of prognosis of acute kidney
disease. Chinese Journal of Integrated Traditional and Western Medicine, 10(1), pp.44-45): group A for patients with no obvious foot-process lesion; group B for patients with segmental foot-process; group C for patients with massive foot-process. The three groups were reviewed in the
aspects of baseline clinical indicators and Oxford classification, so as to discover foot-process’ effect on patients with IgA nephropathy. Results: A total of 129 patients with IgA nephropathy were included in the study. Concerning about the clinical baseline indicators related
to the degree of foot-process, the 24-hour proteinuria level at admission was statistically significant and positively correlated (r = 0.324, P = 0.000). The comparison between groups showed there was statistically significant difference between group C and group A and group
B (P = 0.001, P = 0.035). According to the Oxford Classification, only the differences of mesangial hypercellularity (M) and segmental sclerosis/adhesion (S) were statistically significant (r = 0.239, P = 0.006; r = 0.257, P = 0.003) and were positively
correlated. In terms of mesangial hypercellularity (M), the differences between group A and B, group A and C were statistically significant (P = 0.01, P = 0.003). The comparison between group B and group C showed statistical difference (P = −0.031) in segmental sclerosis/adhesion
(S). Among the 76 patients with S0 revealed by the Oxford classification, there were 55 patients of glomerulosclerosis, which was positively correlated with the degree of foot process (r = 0.211, P = 0.016). The comparison between group A and group C showed statistical difference
(P = 0.014). Conclusion: The severity foot-process was positively correlated with the level of proteinuria. Foot-process is positively related with mesangial hypercellularity, segmental sclerosis and glomerulosclerosis. With more severe the foot-process, there will be more serious
mesangial hypercellularity and irreversible glomerular injury. Foot-process is positively correlated with Lee’s Pathological Grading.

Authors: Bing Shen , Bo Hou , Shibin Zhang
Published: June 2021

This article is based on the use of GE combined with longitudinal lag time to quantify cardiac MRI screening for amyloidosis autologous thousand-cell transplantation, combined with clinical routine risk stratification, method for risk assessment of patients with amyloidosis and monitor
the patient’s evaluation of the efficacy after treatment. Cardiac involvement with systemic amyloidosis is of great significance for both treatment and prognosis assessment, and is essential for quantitative and qualitative diagnosis or objectively providing prognostic value. In summary,
myocardial amyloidosis needs to be studied before heart failure. It is recommended that patients undergo routine cardiac MRI examination to comprehensively evaluate cardiac morphology, function, risk stratification, prognosis, and treatment guidance. Diagnosis based on a single modality has
been replaced by a comprehensive multi-modality method, and there is sufficient evidence to show the potential value of cardiac. However, with the continuous improvement of quality and value in the medical field, the field of cardiac will inevitably develop. The predicted and baseline indexes
of myocardial strain predicted cardiac remission were 0.96 and 0.79, respectively. When the predictive value of clinical routine indicators and cardiac indicators is analyzed using blood response as the evaluation standard, the reduction in end-diastolic volume/body surface area (P = 0.031)
can predict complete haematological remission. Folded cross-validation test shows that the end-diastolic volume/body surface area reduction and the baseline index IgG combined with myocardial strain predict AUC of complete blood remission of 0.78 and 0.76, respectively. This study will also
continue to follow up and increase the sample size to verify the current conclusions.
Transesophageal Ultrasound in Perioperative Hemodynamic Analysis of Off-Pump Coronary Artery Bypass Grafting
Authors: Zhang Shuangyin , Yu Min , Xu Xu , Jin Ping , Jia Juan
Published: June 2021

Transesophageal echocardiography (TEE) can directly, real-time, and visually monitor cardiac structure, function, and volume status, and effectively guide perioperative volumetric therapy and vasoactive drug use in critically ill patients to improve rehabilitation treatment and prognosis.
Therefore, TEE is considered to be the most comprehensive monitoring technology. The characteristics of reliability, continuity, and repeatability of TEE-guided perioperative hemodynamic management make it have obvious advantages in clinical application, and have gradually developed into a
technology that anesthesiologists must master. In this article, we carried out the application of transesophageal echocardiography in perioperative hemodynamic management, with a view to providing clinical research evidence for further promoting the clinical application of TEE and optimizing
the quality of perioperative hemodynamic management in critical patients. The experimental results show that before and after cardiopulmonary bypass, there is a decrease after cardiopulmonary bypass, but it is not reflected in invasive pressure monitoring. It is considered that the volume
change is small, and it has not yet caused the pressure change. In other words, the pressure is estimated to some extent. The load state sensitivity is poor and can not really reflect the change of the front load. Compared to the large number of applications to assess systolic function, there
are few studies using estimated left ventricular diastolic function. In addition to the complexity of the diastolic process itself, the area curve is susceptible to clutter interference, and the poor readability of the time differential curve is directly related.

Authors: Mingjun Tian , Minjuan Zheng
Published: June 2021

According to clinical features and ultrasonic imaging features of patients with absence of pulmonary artery, it is necessary to analyze ultrasonic imaging features of absence of pulmonary artery to provide clinical basis for improving the diagnostic value and prognosis. The data and
color Doppler echocardiography of 45 patients with absence of pulmonary artery are collected, who are confirmed by cardiac catheterization, CTA and operation, and the clinical features and ultrasonic imaging features are studied. The research results show that 57% of the patients have left
absence of pulmonary artery and 91% of them have other cardiovascular malformations, where ASD/PFO is the most common, PDA and VSD are the second. Patients with UAPA have changes of pulmonary artery, the incidence of pulmonary artery abnormalities in multiple malformations, changes of ASD/PFO,
PDA and VSD are mainly pulmonary hypertension. The ejection fraction of patients with UAPA is normal. The main manifestation of pulmonary hypertension is the increase of right cardiac volume load, and the main manifestation of pulmonary stenosis is the increase of collateral circulation. Pulmonary
hypertension and its associated cardiovascular malformations may be related to the prognosis of patients. Ultrasound doctors should understand such diseases to improve the diagnosis rate and the prognosis.
Use of Three-Dimensional Printing in Modelling an Anatomical Structure with a High Computed Tomography Attenuation Value: A Feasibility Study
Authors: Kariyawasam Lakna N. , Ng Curtise K. C. , Sun Zhonghua , Kealley Catherine S.
Published: June 2021

Introduction: Three-dimensional (3D) printing provides an opportunity to develop anthropomorphic computed tomography (CT) phantoms with anatomical and radiological features mimicking a range of patients’ conditions, thus allowing development of individualised, low dose
scanning protocols. However, previous studies of 3D printing in CT phantom development could only create anatomical structures using potassium iodide with attenuation values up to 1200 HU which is insufficient to mimic the radiological features of some high attenuation structures such as cortical
bone. This study aimed at investigating the feasibility of using 3D printing in modelling cortical bone with a non-iodinated material. Methods: This study had 2 stages. Stage 1 involved a vat photopolymerisation 3D printer to directly print cube phantoms with different percentage compositions
of calcium phosphate (CP) and resin (approach 1), and approach 2 using a material extrusion 3D printer to develop a cube mould for infilling of the CP with hardener as the phantom. The approach able to create the cube phantom with the CT attenuation value close to that of a tibial mid-diaphysis
cortex of a real patient, 1475±205 HU was employed to develop a tibial mid-diaphysis phantom. The mean CT numbers of the cube and tibia phantoms were measured and compared with that of the original CT dataset through unpaired t-test. Results: All phantoms were scanned by CT using
a lower extremity scanning protocol. The moulding approach was selected to develop the tibia middiaphysis phantom with CT attenuation value, 1434±184 HU which was not statistically significantly different from the one of the original dataset (p = 0.721). Conclusion: This
study demonstrates the feasibility to use the material extrusion 3D printer to create a tibial mid-diaphysis mould for infilling of the CP as an anthropomorphic CT phantom and the attenuation value of its cortex matches the real patient’s one.
Evaluation of Radiation Doses from Computed Tomography Conducted in Al Jouf Region (Saudi Arabia)
Authors: Alrowaili Ziyad Awadh , Ashari M.
Published: June 2021

A safe radiation dose from computed tomography (CT) is normally specified through the Computed Tomography Dose Index (CTDI) as an “effective dose.” Radiation exposure from CT is relatively high in comparison with other radiological tests. In this paper, we evaluate doses
used on adult patients during typical CT scans, in Al Jouf, the northern region of Saudi Arabia. Scanning processes were taken place in different parts of the body; including the pelvis, head, abdomen, and chest. The dose indices were calculated using the CT-expo v2.5 computer software. A
comparison of the results with similar investigations, regionally and globally, was made. Other comparisons between displayed and calculated dose indices were also performed. The main values of CT volume are the dose index (CTDIvol) and dose-length product (DLP). The effectiveness results
for head CTs were 45.0 mGy, 488 mGy.cm, and 5.2 mSv; while for pelvic CTs they were 16.4 mGy, 391 mGy.cm, and 4.0 mSv; whereas for abdominal CTs they were 22.2 mGy, 613 mGy.cm, and 6.5 mSv; finally they were 17.5 mGy, 380 mGy.cm, and 3.9 mSv for chest CTs. It is confirmed that the values obtained
are within the internationally accepted values, except for the values of the head examination, in which the effective dose value of 5.2 mSv was higher than the recommended value. This work gives an overview of the doses received by adult patients during regular CT examination. It is the first
regional CT dose survey and provides a baseline for improvement and quality control in the region of Al Jouf.
Analysis and Management of Flu Disease Public Opinion Based on Machine Learning
Authors: Zhang Jie , Yuan Chao
Published: June 2021

In the new media era, there are more ways of information dissemination, and the speed of information dissemination becomes faster. Along with it, various public opinions and rumors flood the cyberspace. As a mainstream social media information publishing platform, microblog has become
the main way for netizens to obtain, disseminate and publish information. Because microblog can freely make speeches, and has a fast transmission speed and a wide range, it is easy for public opinion information to be widely disseminated in a short time. In particular, information such as
rumors in public opinion can affect the network environment and social stability. Therefore, it is necessary to analyze and predict public opinion changes and to provide early warning. The literature uses the classic BP-NN (BP-NN) as the base prediction model, and uses the information published

Multimodal medical imaging is an indispensable requirement in the treatment of various pathologies to accelerate care. Rather than discrete images, a composite image combining complementary features from multimodal images is highly informative for clinical examinations, surgical planning,
and progress monitoring. In this paper, a deep learning fusion model is proposed for the fusion of medical multimodal images. Based on pyramidal and residual learning units, the proposed model, strengthened with adaptive fusion rules, is tested on image pairs from a standard dataset. The potential
of the proposed model for enhanced image exams is shown by fusion studies with deep network images and quantitative output metrics of magnetic resonance imaging and positron emission tomography (MRI/PET) and magnetic resonance imaging and single-photon emission computed tomography (MRI/SPECT).
The proposed fusion model achieves the Structural Similarity Index Measure (SSIM) values of 0.9502 and 0.8103 for the MRI/SPECT and MRI/PET MRI/SPECT image sets, signifying the perceptual visual consistency of the fused images. Testing is performed on 20 pairs of MRI/SPECT and MRI/PET images.
Similarly, the Mutual Information (MI) values of 2.7455 and 2.7776 obtained for the MRI/SPECT and MRI/PET image sets, indicating the model’s ability to capture the information content from the source images to the composite image. Further, the proposed model allows deploying its variants,
introducing refinements on the basic model suitable for the fusion of low and high-resolution medical images of diverse modalities.

Objective: The health management of pregnant women in late pregnancy is difficult. Once vaginal infection occurs, adverse pregnancy outcomes will occur. The aim of this study was to explore the application value of biostatistics health assessment of matrix metalloproteinases
(MMP) in vaginal secretions in late pregnant women with vaginal infection. Methods: A total of 120 late pregnant women with vaginal infection, including vulvovaginal candidiasis (WC) in 70 cases and bacterial vaginosis (BV) in 50 cases, were selected as the experimental group. Another
80 pregnant women with normal vaginal secretion in the same gestational week were randomly selected as the control group. Vaginal soft capsule of mycomycin was used in the treatment. The expression levels of MMP-8 and MMP-9 in vaginal secretions before and after treatment were detected by
enzyme-linked immunosorbent assay (ELISA) and smear immunohistochemistry, Results: Both the ELISA and immunohistochemistry analysis showed that the levels of MMP-8 and MMP-9 in the vaginal secretion of experimental group were significantly increased than the data of control group (P
< 0.05). After effective intervention, the levels of MMP-8 and MMP-9 were significantly lower than those before treatment (P < 0.05). Conclusion: The late pregnant women with vaginal infection was accompanied by the high level of MMP-8 and MMP-9 in vaginal secretions. Effective
intervention will lead the reduction of MMP. Thus, the biostatistics health assessment of MMP is important for the late pregnant women with vaginal infection.

Alzheimer’s Disease (AD) is a progressive and irreversible neurodegenerative condition, which results in dementia. Mild Cognitive Impairment (MCI) is an intermediate state between normal aging and AD. Instead of traditional questionnaire method, magnetic resonance imaging (MRI)
can be used by radiologists to diagnose and screening AD recently, but long acquisition time is not conducive to screening AD and MCI. To solve this problem, we develop a Fasu-Net (Fast Alzheimer’s disease Screening neural network with Undersampled MRI) for AD and MCI clinical classification.
The network uses undersampled structural MRI with a shorter acquisition time to improve the screening and diagnosis efficiency of AD. For achieving the best classification result, three axial planes of brain MR images were feed into the Fasu-Net with transfer learning method. The experiment
results on undersampled 3D T1-weighted images database (ADNI) show that in the AD versus MCI versus HC (Healthy Controls) classification, the Fasu-Net achieved the accuracy of 91.41%, thus can be a potential method for fast clinical screening of AD.

Published: June 2021

The united consequences of diffusion thermo as well as radiation absorption on magnetohydrodynamic (MHD) complimentary convection revolving flows of nanofluids over a semi unlimited porous stirring plate by the invariable temperature resource are investigated. Utilizing the perturbations methodology, the velocity distributions,temperatures as well as the concentrations distributions are obtained and examined through their graphical representation. Besides that, the skin friction coefficient, Nusselt number as well as the Sherwood number are obtained analytically and are also arithmetically discussed with reference to the leading parameters. It is observed that the diffusion thermo parameter or the radiation absorption parameter augments the velocity in addition to the fluid temperatures throughout the fluid region. This enhancement is most significant for silver nanoparticles. This is owing to the higher conductance of the solid particles of Ag than that of TiO2. It is also observed that the concentration frontier layer thickness reduces by an increase in the chemically-reacting parameter. This is because the chemically molecular diffusivity decreases for higher quantities ofKr. Also,the Nusselt number reduces while the Sherwood number enhances by increasing the value of the suction parameter.
Radiation and Mixed Convection Magnetohydrodynamics Boundary Layer of Hybrid Cu–Al2O3/Water Nanofluid Flow Over a Wall Jet
Authors: Aly Emad H. , Pop I.
Published: June 2021

The mixed convection MHD boundary layer flow of the hybrid nanofluid (copper–titanium dioxide/water) over a permeable wall jet surface subject to thermal radiation was studied with the effects of suction/injection and thermal energy. The governing PDEs were converted into non-linear
ODEs by using the proper similarity transformations. Then, these equations were numerically solved applying the method of Chebyshev pseudo spectral differentiation matrix (ChPDM). The results were deduced for the flow field, temperature distribution, reduced skin friction coefficient and reduced
Nusselt number. It was found that the hydrodynamic and thermal boundary layers decreases and increases, respectively, as the strength of the magnetic field increases. Further, in the industrial applications, the normal angle is to be applied if low velocity and high temperature is needed.
Moreover, as the mixed convection parameter rises, the velocity and temperature increases and decreases, respectively. In addition, it was mentioned that the radiation parameter can control the thermal boundary layer. Finally, the Cu-nanoparticles volume fraction plays a very important role
in the velocity variation.
