Authors: Bertuzzi Vanessa , Semonella Michelle , Castelnuovo Gianluca , Andersson Gerhard , Pietrabissa Giada
Published: March 2023

BACKGROUND

Internet-based self-help interventions have the potential to help people address their emotional needs at relatively low costs. However, if the system does not offer optimal functions, it could reduce end-users' adherence and satisfaction with the treatment, therefore possibly compromising the effectiveness of the program

OBJECTIVE

This study evaluated the usability of an Internet-delivered self-help intervention for emotional self-management among the general population in Italy during the COVID-19 pandemic. The main goals were to (1) collect qualitative and quantitative data on usability and (2) identify usability problems.

METHODS

A balanced gender-age sample of 10 individuals meeting the inclusion criteria were consecutively recruited online. The think-aloud testing method, the system usability scale, and an ad hoc semi-structured interview were employed to determine the overall system usability.
The quantitative data were analyzed using descriptive statistics and the qualitative data were analyzed for content using thematic analysis.

RESULTS

The participants were mostly satisfied with the overall usability of the program. Still, some usability problems were encountered by older (≥45 years) users, who took longer, made more mistakes, and needed more help in performing the tasks than their younger counterparts. The mean perceived usability score was 68,25 - classified as “good”. The analysis of the interviews revealed 3 central themes: general thoughts about the platform, weaknesses of the platform and difficulties encountered while navigating and completing tasks, and strengths of the platform.

CONCLUSIONS

Conducting usability testing was a crucial step at an early stage of the development process of an Internet-based self-help intervention to identify potential problems of usability with the system. Based on the results of this study, important improvements will be made before the RinasciMENTE program will be tested in real-world conditions.

Empowerment Enabled by Information and Communications Technology and Intention to Sustain a Healthy Behavior: Survey of General Users (Preprint)
Authors: Alluhaidan Ala Saleh , Chatterjee Samir , Drew David E , Ractham Peter , Kaewkitipong Laddawan
Published: March 2023

BACKGROUND

Most people with chronic conditions fail to adhere to self-management behavioral guidelines. In the last 2 decades, several mobile health apps and IT-based systems have been designed and developed to help patients change and sustain their healthy behaviors. However, these systems often lead to short-term behavior change or adherence while the goal is to engage the population toward long-term behavior change.

OBJECTIVE

This study aims to contribute to the development of long-term health behavior changes or to help people sustain their healthy behavior. For this purpose, we built and tested a theoretical model that includes enablers of empowerment and an intention to sustain a healthy behavior when patients are assisted by information and communications technology.

METHODS

Structural equation modeling was used to analyze 427 survey returns collected from a diverse population of participants and patients. Notably, the model testing was performed for physical activity as a generally desirable healthy goal.

RESULTS

Message aligned with personal goals, familiarity with technology tools, high self-efficacy, social connection, and community support played a significant role (P<.001) in empowering individuals to maintain a healthy behavior. The feeling of being empowered exhibited a strong influence, with a path coefficient of 0.681 on an intention to sustain healthy behavior.

CONCLUSIONS

The uniqueness of this model is its recognition of needs (ie, social connection, community support, and self-efficacy) to sustain a healthy behavior. Individuals are empowered when they are assisted by family and community, specifically when they possess the knowledge, skills, and self-awareness to ascertain and achieve their goals. This nascent theory explains what might lead to more sustainable behavior change and is meant to help designers build better apps that enable people to conduct self-care routines and sustain their behavior.
Predicting Immunogenicity of COVID-19 Vaccines in Hemodialysis Patients with Renal Disease (Preprint)
Authors: Alqahtani Saeed Awad M
Published: March 2023

UNSTRUCTURED

Individuals who are diagnosed with chronic kidney disease, particularly those receiving maintenance hemodialysis treatment, face a greater likelihood of suffering from severe symptoms and fatality due to COVID-19. This study aimed to explore the optimal vaccination approach for these individuals. The study used data analysis tasks such as data preprocessing, cleaning, and exploration, and machine learning models like Ridge, Lasso, and Linear Regression were used to construct the predictive model. The study found that the Lasso model is effective in predicting anti-S IgG antibodies levels in response to COVID-19 vaccines for people with kidney failure. The results also suggest that machine learning models can predict the duration of immunogenicity, with the Random Forest model and the ensemble model being the most effective. However, further research is required to validate these models and extend their application to different populations and vaccine types, as well as considering other factors that may affect immune response to COVID-19 vaccines. These findings can be helpful in improving vaccination strategies and promoting public health.
An Analysis of Men and Women’s Exist Plight from a Feminist Perspective: Taking Mrs. Dalloway as an Example
Authors: XIONG Siyu
Published: March 2023

Virginia Woolf’s Mrs. Dalloway is the pinnacle of stream-of-consciousness fiction. Scholars have mostly focused their studies on aspects such as the novel’s stream-of-consciousness techniques and the theme of death. From a feminist perspective, this paper analyzes oppression and its reason caused by the patriarchal society through the physical and spiritual survival plight of men and women in the novel, as well as the resistance and self-redemption of the two main characters when facing exist plight. It shows that Woolf cares for both women and men, and ultimately focuses on the eternal proposition of “man” with a humanistic mindset.
Keats’ Gender Ambivalence: Porphyro’s Dominance and Passivity in “The Eve of St. Agnes”
Authors: Cheng Song
Published: March 2023

This essay studies how the portrayal of characters in “The Eve of St. Agnes” relates to gender issues from the views of feminism. In this long poem, the reinforced patriarchal ideology presented through Porphyro’s dominance – his “stratagem”, his “male gaze” and his “hunting”, and the undermined and even reversed patriarchal ideology presented through Porphyro’s passivity – his “being gazed” and Madeline’s “resistance”, intermingle with each other. As a result, “The Eve of St. Agnes” is an ideologically conflicted text in that it both strengthens and weakens patriarchal ideology, which is largely due to Keats’ gender ambivalence. Porphyro’s dominance and passivity are externalized display of Keats’ inner conflicts caused by gender ambivalence. Eventually, Keats ends this conflict by offering a solution: to reach an androgynous equilibrium between the two ends of his internal gender tension, transcending traditional gender determinations. It is concluded that this solution allows Keats’ two selves to get reconciled and liberated in his poetry.

Authors: KANAWJIA PREETI , GUPTA ANUPAMA , CHAUDHARY MADHU
Published: March 2023

Objective: The aim of the study was to study the degree of compliance of primary care anesthesia dispensing companies in following the pricing norms set by drug price control order 2013 (DPCO).
Methods: This is an observational and analytical study where the dosage, strength, and ceiling price of the generic primary care anesthetics were obtained from the National pharmaceutical pricing authority updated price list 2022 and similar data of their various counterpart brands were obtained from www.medguideindia.com. Thereafter, comparisons of their ceiling price along with the brands cost range, cost ratio, and percent cost variation were sought.
Results: Our study retrieved 150 brands of total 11 injectable/topical primary care anesthetics available in India of which 39.33% brands had prices more than DPCO recommended ceiling price. Maximum price violation (90%) was noticed with brands of Inj. Midazolam 5 mg/mL. The maximum cost variation and cost ratio was seen with brands of Inj. Lignocaine 1–2% (10 mg/mL) of 148.37% and 149.37, respectively.
Conclusion: The adjuvant sedative hypnotic, Midazolam which is often used to supplement the action of primary sedative hypnotics in inducing general anesthesia, violating price ceiling is a matter of great concern as it would adversely impact the primary patient care; the most basic level of health care which almost whole population needs at some time or the other. Similarly adding to the misery of the common man is the maximum cost ratio and percent cost variation of the local anesthetic, Inj. Lignocaine 1–2% as it continues its prominence as the most widely used local anesthetic agent.

Authors: Bodapati Sunitha , Parvataneni Radhika , Kakaraparthi Yasoda devi , Punnapu Vijayakumar
Published: March 2023

Objective: The thyroid gland has a very important role in hematopoiesis. Blood disorders are frequently seen in patients with thyroid dysfunction and anemia is more common in them. Thyroid hormones directly affect blood parameters by stimulating erythrocyte precursors and indirectly by enhancing erythropoietin production. The present study was conducted to evaluate the effect of hypothyroidism on different hematological parameters.
Methods: This is a prospective observational study which included a total of two hundred individuals. They are enrolled and divided into two equal groups; each group consists of one hundred individuals. The first group consists of one hundred cases of hypothyroidism, whose blood cell indices are compared with one hundred healthy individuals as a control in the second group. Patients with diabetes mellitus, hyperthyroidism, congenital thyroid disorders, thyroid malignancies, hemolytic anemia’s, aplastic anemia, malignancies, leukemias and blood dyscrasias were excluded from the study.
Results: The analysis showed a significant difference in the hemoglobin, RBC count, hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), and red cell distribution width (RDW) (p values 0.000, 0.000, 0.000, 0.000, 0.002, 0.000, and 0.022), respectively, while platelets and WBC showed no significant correlation (p values 0.410 and 0.6420).
Conclusion: In this study, most of the hematological parameters in hypothyroid cases are significantly low, except RDW levels which are high among them. Platelet count and WBC are less affected in cases when compared with the controls, and the study indicates that anemia is associated with hypothyroidism. The follow-up of patients with thyroid disorders should include the complete blood count and patients diagnosed with anemia should also be evaluated for thyroid disorders before iron therapy or any other therapies. Cases of anemia which are not responding to treatment should be investigated for the possibility of thyroid dysfunction.

Objective: Lichtenstein method is a gold standard surgery modality for the management of inguinal hernia but it is associated with post-operative complications such as groin pain, abdominal wall thickness, and surgical site infections. Desarda method is a physiologic non-mesh repair with no anticipated mesh related complications. The present prospective randomized study was conducted to compare short term outcomes of Desarda with Lichtenstein technique for the management of inguinal hernia.
Methods: This was a prospective randomized study conducted on 60 patients undergoing surgery for inguinal hernia. The patients were allocated into two groups as follows, Group A (n=30) patients undergoing Desarda’s repair for inguinal hernia and Group B (n=30) patients undergoing Lichtenstein’s repair. The following outcome was measured, post-operative pain (Day 1, Day 3, Day 5) – visual analog scale, duration of hospital stay and complications. p value <0.05 was considered significant.
Results: The demographics characteristic were similar in both the groups and not significant. The hospital stay duration was lower in Desarda group as compared to Lichtenstein groups and was significant (4.07±0.83 vs. 6.87±1.87 days). The post-operative VAS score at day 1, 3, and 5 were significantly lower in Desarda group as compared to Lichtenstein group. The incidence of complications were lesser in Desarda group as compared to Lichtenstein group but not significant.
Conclusion: The Desarda technique was superior when compared to Lichtenstein method in terms of early recovery, post-operative pain, and complications for the management of inguinal hernia.

Double-Sided LCC Compensation Network and Its Tuning Method for Wireless Power Transfer for EV charging
Authors: Rohith Choppadandi , Indumathi Boddupally
Published: March 2023

Abstract: This research explores a double-sided LCC compensation network's utilization in an inductively coupled wireless power transfer (WPT) system for electric car charging applications and its wireless power transfer tuning procedure (WPT). A wireless power transmission system is offered with a double-sided LCC compensating network. The compensation circuit is crucial because it may be used to adjust the system's resonance frequency, lower reactive power in the power electronics converter, and boost the efficiency and capability of transferred power. The proposed architecture and its tuning technique allow the system to operate at a constant switching frequency since the resonant frequency is unaffected by the coupling coefficient between the two coils and is also independent of the load status. Also, it has been discovered that the corrected receiving coil inductance is a useful tuning parameter for ensuring the primary side zero voltage switching (ZVS) operation.

Published: March 2023

Abstract: In this study, port injection single-cylinder HCCI engines were used to conduct an experimental investigation into the impact of diesel-Eucalyptus fuel blends on HCCI engine performance and exhaust pollutants. In the tests, eucalyptus and diesel were blended in a variety of volume ratios as test fuels, including 20% eucalyptus to 80% diesel (Eu20/D80), 40% eucalyptus to 60% diesel (Eu40/D60), 60% eucalyptus to 40% diesel (Eu60/D40), and 100% diesel. The tests were performed at a 1500 rpm engine speed with a 19-compression ratio at inlet air temperatures between 70° and 130°C. This study observed at the variations in brake thermal efficiency, exhaust gas temperature, and carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxide (NOx) emissions. According to test results, HCCI with diesel-Eucalyptus fuel blends increases brake thermal efficiency, exhaust gas temperature, decreases carbon monoxide, unburned hydrocarbons at inlet temperatures of 130°C, and decreases nitrogen oxides at inlet temperatures of 70°C. It was subsequently found that diesel-Eucalyptus fuel mixtures significantly affected the output and exhaust emissions of HCCI engines.

A GUI Based Application for Lung Cancer Diagnosis Using Comprehensive Analysis Deep Learning Approach
Authors: S Akhil Kumar , Gangyada Sai Krishna , Immadi Gifty Joyce , Reddy H Venkateswara
Published: March 2023

Abstract: Lung cancer is the third most terrible cancer in the world. It has been among the leading causes of death in both adults and children from recent years. Early cancer detection can lead to better treatment options for patients. The focus of conventional feature extraction methods is either on low -level features or high-level features, with some manually created features being utilized to fill in the gaps. A feature extraction framework does not require handcrafted features can be created to close this gap via encoding/combining low-level and high-level characteristics. Due to its ability to fully explain both low-level and high-level information and its integration of the feature extraction stage into the self-learning process, deep learning is incredibly effective for feature representation. Consequently, in this study, we use deep learning algorithms to detect the presence of lung cancer without the need for several doctor consultations. A web application is created as a healthcare application where lung cancer is detected using an input x-ray image. To identify cancer, the implementation uses the VGG-16 classification algorithm. As a result, the presence of the disease can be predicted early. We can then take quick action to stop any additional repercussions, which saves time, money, and human error. Lung cancer and its presence are identified in this investigation.

Abstract: Effect of different concentrations on total leaf protein content was studied in three economically important plant species, viz., tomato, mung bean and maize. Different treatments of SO2 exposure were administered in artificial fumigation chambers. Maize showed least reduction in total proteins. Tomato exhibited maximum decline in protein content after SO2 fumigation. Relationship between individual and interactive effects of SO2 concentration were analyzed with the help of a statistical regression model. Present study helps to establish a correlation between the total leaf protein content, free radicals, activities of antioxidant enzymes like superoxide dismutases and peroxidases and plant sensitivity to SO2 under ambient conditions as well as in greenhouse environment

En México, los agricultores de pequeña escala presentan deficiencia en conocimientos y en la organización para aprovechar efectivamente el potencial natural y el capital social, que son aplicados en la transferencia de tecnología en los sistemas productivos, a pesar de la incidencia de programas de capacitación por parte del gobierno y otras organizaciones. La investigación se realizó en dos comunidades rurales con marginación alta; participaron catorce productores que fueron seleccionados mediante un muestreo no probabilístico y como criterio para participar fue que cada uno de los participantes se dedicaran a cultivar y que en sus terrenos tuvieran frutales de durazno. Se encontró que los efectos de enseñanza –aprendizaje que se aplican en las escuelas de campo (EC’s), para el manejo de la milpa intercalada con árboles frutales (MIAF), no influyeron en el capital social, ni la formación de redes sociales para la difusión de tecnología. Se concluye que las EC’s, a pesar de utilizar ciertas dinámicas para fortalecer el aprendizaje, es necesario que, en su metodología, inicialmente implementen estudios para conocer intereses, actitudes y habilidades de los productores.
Parity Quantum Optimization: Encoding Constraints
Authors: Drieb-Schön Maike , Ender Kilian , Javanmard Younes , Lechner Wolfgang
Published: March 2023

Constraints make hard optimization problems even harder to solve on quantum devices because they are implemented with large energy penalties and additional qubit overhead. The parity mapping, which has been introduced as an alternative to the spin encoding, translates the problem to a representation using only parity variables that encodes products of spin variables. In combining exchange interaction and single spin flip terms in the parity representation, constraints on sums and products of arbitrary k-body terms can be implemented without additional overhead in two-dimensional quantum systems.

Californium was first produced by Stanley G. Thompson, Glenn T. Seaborg, Kenneth Street, Jr.and Albert Ghiorso working at the University of California, Berkeley, in 1950. The technologies of neutronsources production developed by RIAR are reviewed. To produce 252Cf-containing core, differenttechniques are used depending on the source type. They are: impregnation of foam-alundum billets, glassbeads and cermets production (point sources), electroplating on the platinum cathode (linear sources).Neutron sources produced by RIAR are one- or two-capsule design. Capsules are made of stainless steeland argon arc-welded. Neutron output of the sources varies from 1 x 10 to 2 x ю10 cm-2 s-1. Sources arewidely used in medicine, industry, and research work. These isotopes of element 116 are the decaydaughters of element 118 isotopes, which are produced via the 249Cf+48Ca reaction
