Authors: Oliveira Matildes José , Zanini Daniela Sacramento 
Published: February 2023

Um estudo sobre autoeficácia, bem-estar subjetivo e desemprego, tendo como objetivo verificar a relação entre os aspectos pessoais (dados demográficos), autoeficácia e bem-estar subjetivo em trabalhadores desempregados da cidade de Goiânia-Go, e região metropolitana. Ele está estruturado em duas partes. Na primeira, faz-se uma revisão teórica sobre o tema, com levantamento histórico sobre a categoria trabalho, pontuando seus índices na atualidade. Apresentando as abordagens teóricas de autoeficácia fundamentadas nas teorias de Albert Bandura que sustentam esse construto, e, também, os conceitos e reflexões referentes a bem-estar subjetivo. Na segunda parte, apresentam-se alguns estudos empíricos de diversos pesquisadores sobre o tema e a pesquisa deste trabalho, que dispôs de uma amostra que incluiu 254 desempregados da cidade de Goiânia e região. Os dados foram obtidos por meio das agências do Sistema Nacional de Emprego (Sine), empresas de recursos humanos e uma escola de educação para jovens e adultos. Foram utilizados como instrumentos de investigação um questionário sociodemográfico com itens relacionados ao desemprego, uma escala de autoeficácia contendo 19 itens relacionados à questão do desemprego elaborada por Campos (2011) e uma de bem-estar subjetivo (Ebes), a qual contempla 47 itens que medem afeto positivo e negativo, elaborada e validada por Albuquerque e Trócolli em 2004. A coleta de dados restringem-se a órgãos e empresas de cidade de Goiânia. Os dados revelam que uma parte significativa dos desempregados são provenientes de outros estados e o perfil das pessoas pesquisadas encontra-se em consonância com o parâmetro nacional. Foram analisados a regressão entre a autoeficácia, sexo, idade, tempo de desemprego e bem-estar subjetivo dos desempregados. Os resultados revelam que o afeto positivo é explicado em 25% pelas variáveis sexos (beta = 0,22 e p = 0,003) e autoeficácia (beta = 0,41 e p = 0,000). Contudo, a idade e tempo de desemprego não explicam afeto positivo relatado pelos desempregados.

Authors: Maurya Jayanand , Joshi Y. C. , Panchal A. , Gour A. S. 
Published: February 2023

Abstract
We study variable stars in the field of the open cluster NGC 381 using photometric data observed over 27 nights and identify a total of 57 variable stars, six of which are member stars. The variable stars are classified based on their periods, amplitudes, light-curve shapes, and locations in the H-R diagram. We found a rich variety of variable stars in the cluster. We identified a total of 10 eclipsing binaries, of which two are of Algol type while eight are of W UMa type (EW). The estimated ages of these EW binaries are greater than 0.6 Gyr, which is in agreement with the formation time constraint of ≥0.6 Gyr on short-period eclipsing binaries. The physical parameters of the two EW-type binaries are estimated using PHOEBE model-fitting software. The pulsating variable stars include one each from the δ Scuti and γ Dor variability classes. We determined the pulsation modes of pulsating variables with the help of the FAMIAS package. We obtained 15 rotational variable stars comprising four dwarf stars identified on the basis of their log(g) versus log(T
eff) diagram. These dwarf stars are found to have generally longer periods than the remaining rotational variables.
Merleau-Ponty’s Embodied Phenomenology and the Multiplicity of Trans Narratives
Authors: Hetterley Jae 
Published: February 2023

Être transgenre implique des relations uniques à son propre corps, ainsi que la question du récit dans la formation du sujet – deux thèmes-clés chez Merleau-Ponty. Mais même si l’on accepte d’aller au-delà de l’histoire stéréotypée d’être « pris·e dans le mauvais corps », tant dans les communautés trans que dans le discours public plus large il existe une tendance fâcheuse à universaliser de tels récits – et ce, en dépit de l’hétérogénéité apparente que l’on retrouve dans les descriptions individuelles à la première personne. La question émerge donc à savoir : comment rendre compte philosophiquement de cette différence à la première personne tout en visant une politique de solidarité ? Cet essai cherche à utiliser la phénoménologie de Merleau-Ponty dans un sens pratique, en se concentrant sur sa description du « schéma corporel » pour atténuer cette tension. En effet, tandis que Merleau-Ponty nous fournit un ensemble général d’instruments pour comprendre la relation entre incarnation et comportement, ses exemples phénoménologiques sont souvent fortement singuliers. De la sorte, dans le contexte des subjectivités transgenres, le but est de creuser davantage cet espace discursif, comme prologue pour une praxis qui soit plus réceptive à l’expérience vécue des personnes trans.

Authors: Baillifard Ambroise , Martarelli Corinna S. 
Published: February 2023

Avec la Covid-19, d’aucuns pensaient que les études universitaires allaient être impactées négativement par le passage au tout à distance. La diminution des contacts sociaux, l’éloignement physique de la réalité universitaire et l’ambiance anxiogène pouvaient faire craindre le pire. Deux semestres plus tard, nous faisons un bilan au sein de UniDistance Suisse grâce à deux sources d’informations principales : une comparaison pluriannuelle des taux de décrochage pluriannuels (n=4664) et des résultats notés (n=3577). Des tests de chi-carré de Pearson et U de Mann-Whitney complètent les analyses descriptives. Les résultats interdisent de conclure à un impact négatif significatif de la Covid-19 sur la réussite universitaire d’étudiants non traditionnels, adultes en reprise d’études (âge moyen = 35 ans). Ce constat révèle la résilience et le mérite de la majorité des personnes concernées qui ont pu trouver les ressources pour faire face.

Authors: Bhasin Meenakshi , Singh Harkanwal Preet , Singh Padam , Dhingra Rachna , Kohli Saniya Arora , Azad Anurag 
Published: February 2023

Background:
It is ascertained that the survival rate of patients infected with type 16 human papillomavirus (HPV16) positive is better as compared to those infected with HPV16 negative. The present study was conducted to determine rgw role of HPV16 and risk factors in assessing oropharyngeal cancer (OPC) death.

Methodology:
A total of 102 clinically and histologically proven cases of oral pharyngeal cancer were included. Seropositivity for HPV16 E6 as a marker of HPV16-positive cancer was estimated.

Results:
Out of 102 patients, there were 70 males and 32 females. Significant risk factors associated with OPC survival overall in the univariate analysis was female sex (hazard ratio [HR] 0.54, 95% confidence level [CL]: 0.36–80), alcohol use >2 drinks/day (HR 1.54, 95% CL: 1.12–2.08), smoking >10 pack-years (HR 2.20, 95% CL: 1.42–3.58), moderate dental (HR 1.54, 95% CL: 1.02–2.32), underweight (HR 2.24, 95% CL: 1.34–3.60), and Stage IV cancer (HR 2.82, 95% CL: 1.76–4.40). There was significant low risk for death among HPV16 positive (HR 0.48, 95% CL: 0.32–0.70).

Conclusion:
HPV16 status is an independent prognostic factor for OPC deaths. The common risk factors were female gender, moderate oral care, underweight body mass index, excessive alcohol, and smoking tobacco.

Published: February 2023

Background:
Root resorption is an unwanted phenomenon occurring in a substantial population proportion these days. Hence, the current study was conducted to evaluate root resorption in endodontically treated teeth following fixed orthodontic treatment.

Materials and Methods:
A total of 100 patients were enrolled. Only those patients were enrolled that were scheduled to undergo fixed orthodontic therapy. Pretreatment examination was done in all the patients, and their radiographs were obtained. Both orthopantomograms and peri-apical radiographs were taken. All the patients were recalled on follow-up, and radiographic examination was again carried out. Pretreatment radiographs and follow-up radiographs were compared. The incidence of root resorption was documented. The data were entered in an Excel sheet (Microsoft office version 2007) and analyzed using IBM SPSS software version 20.

Results:
Root resorption was present in 30 patients. Among these 30 patients, 20 were male, whereas 10 were female. In 19 patients, root resorption was present in the maxillary arch, whereas in 11 patients, it was seen in the mandibular arch. The most common tooth involved with root resorption was premolars, followed by anteriors and molars.

Conclusion:
The risk of root resorption is higher in endodontically treated teeth under the influence of orthodontic forces.

Authors: Kumar Shubham , Kumar Saurav , Hassan Nadira , Mazhar Sabika , Anjan Ravi , Anand Bharti 
Published: February 2023

Background:
Corticotomy in fixed orthodontic treatment gives a potential approach to reduce the treatment duration. Typically, this duration of rapid tooth movement lasts 4–6 months.

Aim:
The aim of this study was to compare the treatment outcome and effectiveness in en masse retraction with and without corticotomy.

Materials and Methods:
Thirty-two patients (male 16 and female 16) who opted to undergo surgery to reduce the orthodontic treatment time were chosen for the research, and the group consisted of 26 patients (male 13 and female 13) who did not opt for the corticotomy procedure were selected as the control. There was no blindness of the party distribution. It was focused on the patient's ability to opt for an additional minor surgical procedure that may affect orthodontic treatment length. The operation was conducted under local anesthesia (Lignox 2%). The same maxillofacial surgeon performed all the surgical operations.

Results:
The space present in the maxillary and mandibular arch at the time of retraction had no statistically significant difference in both the control and study groups (P > 0.05). In comparison, the mean amount of retraction space in the maxillary arch and maxillary arch was significant in the control and study groups at 1 month, 2 months, 3 months, and 4 months of the time interval.

Conclusion:
It can be concluded that corticotomy-assisted retraction significantly decreases the total length of orthodontic care. Effectively stationary anchorage segment was made, thereby removing the need for other anchorage boosters, instrumental in maximum anchorage cases using corticotomy technique.

To Evaluate the Role of Positron Emission Tomography-Computerized Tomography in Initial Staging of Carcinoma Breast
Authors: Kansal Anju , Jaswal Gaurav , Garg Shreya , Kang Manraj Singh , Yadav Hanuman Prasad , Banipal Raja Paramjeet Singh , Garg Pardeep , Kaur Taranjeet 
Published: February 2023

Background:
Breast cancer is the most common cancer in urban and second common in rural Indian women. In India, in spite of the best treatment available being given to the patients they lose their lives because of paucity of diagnostic aids and lack of an organized breast cancer screening program. Early detection, accurate staging, and initiation of appropriate therapy are the key factors for improving the treatment outcome and prognosis of the disease for the patients. Traditional staging methods include clinical examination, blood tests, chest X-ray, ultrasound of the abdomen, and/or skeletal survey. As these tests lack sensitivity and specificity, these are being scaled down. The hybrid positron emission tomography-computerized tomography (PET-CT) is a unique tool in the field of imaging modalities that combines the effectiveness of PET and CT. This study was undertaken to assess the efficacy and accuracy of PET-CT as a single-session staging modality in the very initial stage itself and if it can replace the conventional means of staging.

Methods:
This was a cross-sectional study conducted in the Radiotherapy department at GGS Medical College and Hospital Faridkot from March 2014 to October 2015. 52 patients with newly diagnosed and histopathologically proven carcinoma breast were staged by conventional modalities (clinical examination, blood tests, X-ray chest, mammography, ultrasonography abdomen, skeletal survey) and by 18F-fluorodeoxyglucose (18F FDG) PET/CT. PET-CT images were used for the detection, localization, staging of tumors and detection, evaluation, and diagnosis of metastatic lesions, disease burden and organ function along with treatment planning and planning therapeutic procedures. Following the completion of initial study, the results of 18F FDG PET-CT staging in comparison with conventional staging method were assessed. Along with this, the accuracy, changes in staging of cases of carcinoma breast and cost-effectiveness of 18F-FDG PET-CT were also studied.

Results:
All the pathologic entities identified by conventional imaging were also perceived with 18F-FDG PET/CT. Therefore, we recommend the use of PET/CT as an important imaging modality for initial diagnosis of carcinoma breast.

Published: February 2023

Background:
Vascular abnormalities and microvasculopathy are one of the widely accepted factors of diabetic retinopathy (DR). Retinal Neuronal dysfunction and neurodegeneration are also important components in the pathogenesis of DR. However recent investigations show neurodegenerative alterations before the appearance of microvascular changes in patients having DR.

Aims and Objectives:
(1) To measure the macular thickness, retinal nerve fiber layer thickness, and ganglion cell complex thickness among patients with type 2 diabetes mellitus using optical coherence tomography. (2) To compare the macular thickness, retinal nerve fiber layer thickness and ganglion cell complex thickness in type 2 diabetic patients with and without DR with normal controls using optical coherence tomography.

Materials and Methods:
Thirty Patients with type 2 diabetes mellitus without DR, 30 having mild and moderate DR and 30 healthy normals are taken considering the inclusion and exclusion criteria. Macular thickness, retinal nerve fiber layer (RNFL) thickness, ganglion cell layer-inner plexiform layer (GCL-IPL) thickness was measured in each individual and it was compared using one way ANOVA test, post hoc test and Pearson correlation was performed to evaluate the linear correlation between variables and calculated P < 0.05 was regarded as its significance.

Results:
The average RNFL thickness was 90.27 ± 5.57 and 107.7 ± 5.32 um in diabetic patients and controls respectively (P < 0.001). Furthermore, for two different groups of diabetic patients, the average RNFL thickness was 89.92 ± 6.62 um in the no DR group and 78.6 ± 3.93 in the DR group (P = 0.339). The average GCL-IPL thickness was 82.65 ± 2.25 um and 92.10 ± 2.41 um in diabetic patients and controls, respectively (P < 0.001). Furthermore, for two different groups of diabetic patients, the average GCL-IPL thickness was 82.22 ± 2.11 um in the no DR group and 71.55 ± 2.34 in the DR group (P = 0.535). The average macular thickness was 238.03 ± 4.42 and 277.9 ± 5.85 um in diabetic patients and controls, respectively (P < 0.001). Furthermore, for two different groups of diabetic patients, the average macular thickness was 236.56 ± 4.10 um in the no DR group and 242.8 ± 4.95 um in the DR group (P = 0.585).

Conclusion:
There was a statistically significant reduction of mean RNFL, GCL-IPL and macular thickness in type 2 diabetic patients with no DR compared with a homogenous control group indicating neuroretinal changes occur before vascular changes of DR.

Published: February 2023

Background:
Denture during its in vivo service encounters myriad food pigments and numerous physico-mechanical dynamic changes. Denture discoloration is one of the unresolved problems that should be unraveled to satisfy the esthetic demands of the patients.

Aim:
This study aims to evaluate the color stability of a novel denture base copolymer with 10% and 20% (vol/vol) concentration of cycloaliphatic comonomer.

Materials and Methods:
Control group (G0) comprises specimens made without cycloaliphatic comonomer. The specimens of trial groups G10 and G20 were fabricated with 10% and 20% cycloaliphatic comonomer, respectively. For each group, thirty specimens (n = 30) were made. The specimens (n = 10) were immersed in three food colorant solutions (erythrosine, tartrazine, sunset yellow) for 56 days after artificial thermal aging. Ultraviolet-visible spectrophotometer was employed to measure the tristimulus values and calculate the color change (ΔE) of the specimens prior to and following rapid thermal aging or immersion of the specimens in the food colorants.

Results:
G0 showed the highest ΔE and G20 exhibited the least with each colorant. G10 had an intermediate imperceptible ΔE with each colorant. Also, significant differences (P = .000) existed between the food colorants within each group. The highest ΔE value was observed with sunset yellow and the lowest ΔE with tartrazine with each group.

Conclusion:
The addition of cycloaliphatic comonomer in denture base acrylic resins improved the color stability. The new copolymer with 20 Vol.% comonomer exhibited the highest color stability with all the food colorants.
