Dari hasil observasi dan wawancara penulis dengan kepala sekolah, dapat diketahui bahwa sebelumnya belum pernah dilakukan penelitian pada sekolah ini. Kepala sekolah juga menyampaikan bahwa siswa autis yang memiliki kepercayaan diri yang rendah adalah siswa autis dalam kategori ringan. Kepala sekolah menjelaskan berbagai macam tingkah yang dilakukan oleh siswa autis dalam kategori ringan ini, seperti merasa takut saat bertemu dengan orang baru, mereka memiliki persepsi bahwa setiap orang baru itu akan menyakitinya sehingga siswa autis cenderung bersembunyi dan menyendiri. Ada juga siswa autis yang selalu ingin ditemani oleh orang tua atau salah satu dari anggota keluarganya saat berada di sekolah, dikarenakan siswa autis akan merasa aman dengan kehadiran orang terdekatnya tersebut. Penelitian ini bertujuan untuk mengetahui apakah penerapan bimbingan kelompok dapat meningkatkan kepercayaan diri siswa autis di sekolah atau tidak. Penelitian ini menggunakan penelitian eksperimen. Jenis penelitian eksperimen ini adalah Pre-Experimental Design (eksperimen pura-pura) yang model penelitiannya yaitu One Group Pretest-Posttest Design. Populasi dalam penelitian ini adalah seluruh siswa autis yang ada di Sekolah Luar Biaya Autisma Yayasan Pengembangan Potensi Anak Bukittinggi dengan jumlah siswa sebanyak 27 orang. Sedangkan sampel dalam penelitian ini yaitu siswa autis yang mempunyai rasa kepercayaan diri yang tergolong rendah. Cara pengambilan sampel yang digunakan yaitu dengan teknik Purposive Sampling, dan instrumen yang digunakan berupa Skala Likert. Sedangkan uji prasyarat analisis menggunakan uji normalitas dan hipotesis menggunakan Uji Wilcoxon dalam SPSS 20. Hasil penelitian yang telah dilaksanakan dapat diketahui bahwa adanya perbedaan antara nilai pretest dan nilai posttest. Pada nilai pretest terdapat 10 siswa autis dalam kategori sedang dengan persentase 100%. Sementara itu, setelah diberi perlakuan berupa layanan bimbingan kelompok, maka nilai posttest mengalami peningkatan sebanyak 9 siswa autis dalam kategori tinggi dengan persentase 90%. Dari hasil tes statistic dapat diketahui bahwa nilai Z -2,80 dan Asymp. Sig. (2-tailed) bernilai 0,005. Karena nilai 0,005 lebih kecil dari < 0,05 maka dapat disimpulkan bahwa “hipotesis diterima” artinya ada perbedaan antara hasil kepercayaan diri siswa autis untuk pretest dan posttes sehingga bisa disimpulkan bahwa ada pengaruh penggunaan metode bimbingan kelompok terhadap kepercayaan diri siswa autis.
Can Protostellar Outflows Set Stellar Masses?
Authors: Myers Philip C. , Dunham Michael M. , Stephens Ian W. 
Published: May 2023

Abstract
The opening angles of some protostellar outflows appear too narrow to match the expected core–star mass efficiency (SFE) = 0.3–0.5, if the outflow cavity volume traces outflow mass, with a conical shape and a maximum opening angle near 90°. However, outflow cavities with a paraboloidal shape and wider angles are more consistent with observed estimates of the SFE. This paper presents a model of infall and outflow evolution based on these properties. The initial state is a truncated singular isothermal sphere which has mass ≈ 1 M
⊙, freefall time ≈ 80 kyr, and small fractions of magnetic, rotational, and turbulent energy. The core collapses pressure free as its protostar and disk launch a paraboloidal wide-angle wind. The cavity walls expand radially and entrain envelope gas into the outflow. The model matches the SFE values when the outflow mass increases faster than the protostar mass by a factor 1–2, yielding protostar masses typical of the IMF. It matches the observed outflow angles if the outflow mass increases at nearly the same rate as the cavity volume. The predicted outflow angles are then typically ∼50° as they increase rapidly through the stage 0 duration of ∼40 kyr. They increase more slowly up to ∼110° during their stage I duration of ∼70 kyr. With these outflow rates and shapes, the model predictions appear consistent with observational estimates of the typical stellar masses, SFEs, stage durations, and outflow angles, with no need for external mechanisms of core dispersal.
Statistical Recovery of 21 cm Visibilities and Their Power Spectra with Gaussian-constrained Realizations and Gibbs Sampling

Published: May 2023

Abstract
Radio interferometers designed to probe the 21 cm signal from Cosmic Dawn and the Epoch of Reionization must contend with systematic effects that make it difficult to achieve sufficient dynamic range to separate the 21 cm signal from foreground emission and other effects. For instance, the instrument’s chromatic response modulates the otherwise spectrally smooth foregrounds, making them difficult to model, while a significant fraction of the data must be excised due to the presence of radio-frequency interference, leaving gaps in the data. Errors in modeling the (modulated and gappy) foregrounds can easily generate spurious contamination of what should otherwise be 21 cm signal-dominated modes. Various approaches have been developed to mitigate these issues by, for example, using nonparametric reconstruction of the foregrounds, in-painting the gaps, and weighting the data to reduce the level of contamination. We present a Bayesian statistical method that combines these approaches, using the coupled techniques of Gaussian-constrained realizations and Gibbs sampling. This provides a way of drawing samples from the joint posterior distribution of the 21 cm signal modes and their power spectrum in the presence of gappy data and an uncertain foreground model in a computationally scalable manner. The data are weighted by an inverse covariance matrix that is estimated as part of the inference, along with a foreground model that can then be marginalized over. We demonstrate the application of this technique on a simulated Hydrogen Epoch of Reionization Array–like delay spectrum analysis, comparing three different approaches for accounting for the foreground components.
Study the activity of conjugated antimicrobial peptide WW-185 against clinically important bacteria
Authors: Salama Ali H. 
Published: May 2023

Multidrug-resistance bacteria are a serious problem for health specialists and all the people in the world. The main reasons for this problem are the misuse of antibiotics and the limited number of antibiotics as compared to the different human diseases. Important antibiotic-resistant bacteria include Methicillin-resistant Staphylococcus aureus (MRSA) and Extended-Spectrum β-Lactamases E. coli (ESBL E. coli), These two types of bacteria can cause life-threatening diseases and poses a big problem in choosing suitable antibiotics for infections caused by them.
Antimicrobial peptides (AMPs) are considered promising antimicrobial agents that meet the required criteria for novel antimicrobial drugs. This study aims to design novel and safe AMP to be used as antimicrobial agents. In this study, an unique modified AMPs called WW-158 was designed to have a hydrophilic and hydrophobic balance using arginine to represent the cationic part and tryptophan to show the hydrophobic part. It showed good activity against MRSA with a MIC value of 35 μM. These effective concentrations were associated with negligible toxicity toward human red blood cells. Furthermore, our results showed that most of the combined groups of peptides with eight conventional antibiotics displayed synergistic modes of action or additive effects.

Abstract
A 48-year-old woman with a history of dermatomyositis (DMS) presented with 2 weeks of worsening myalgias, weakness, and diffuse edema following cessation of her systemic immunosuppression and subsequently developed severe bilateral vision loss consistent with bilateral frosted branch angiitis. Multimodal imaging was performed, and the patient was successfully treated with pulse-dose steroids and intravenous immunoglobulin, as well as intravitreal aflibercept. Ophthalmic involvement of DMS is typically limited to episcleritis, conjunctivitis, and uveitis. We present an uncommon case of bilateral occlusive retinal vasculitis with frosted branch angiitis in a patient with DMS. The significant improvement anatomically and in visual acuity in our patient suggests a role of combined anti-vascular endothelial growth factor and systemic immunosuppression in the management of DMS -related frosted branch angiitis. We suggest that retinal vasculitis should be considered in patients with known DMS and acute vision loss, with prompt referral for ophthalmologic evaluation.
Adoption of Academic Staff to use the Learning Management System (LMS): Applying Extended Technology Acceptance Model (TAM2) for Jordanian Universities
Authors: Altawalbeh Manal A. 
Published: May 2023

Starting from March of 2020, the outbreak of the COVID-19 caused Jordanian universities to close their campuses and forced them to initiate online teaching. Learning management system (LMS) is an important tool and suitable as tool for learning and activities in a higher education. However, each university has a different LMS tool that allows users to use it in their activities. This paper is interested in investigating the acceptance of Jordanian academic staff in using an LMS after getting back to work post the COVID-19 period. The study sample consisted of 500 faculty members of different ranks, selected randomly from all Jordanian universities, for the second semester of the academic year 2020-2021. The Technology Acceptance Model (TAM2) has been adopted to identify the Acceptance and use of LMS. The questionnaire developed by the researcher was based on past research studies. Simple linear regression was used to calculate the relationships between factors. The research results presented that there is a statistically positive effect of Perceived Usefulness(PU), Perceived Ease of Use (PEOU) and Subjective Norm(SN) on adoption to use LMS, and Perceived Ease of Use(PEOU), lecturers' Image(LI), Subjective Norm(SN), Job Relevance(JR), and, Result Demonstrability(RD) Output Quality(OQ) on Perceived Usefulness(PU). This study indicates that we must always conduct workshops and training programs related to learning management systems and computers to enhance the usability of learning management systems among faculty members
Challenges Impacting Students’ Intention to Effectively Use E-Learning Method in a Virtual Learning Environment

Published: May 2023

During the pandemic period, the education sector was heavily impacted involving transformations of instructional delivery from face-to-face to online mode. To date, we know that the virtual learning environment has been posing heavy demands particularly on the students. Learning from their own homes, they had to learn in isolation, deprived from the support of the instructor and peers as in conventional classrooms. As we continue to pursue online program offerings beyond the pandemic period, it is important to address students’ sense of isolation and their efforts to stay engaged in learning. This study aims to identify the extent to which the challenges students faced in a virtual learning environment during the pandemic, have impacted their intention to effectively use the online learning method. Respondents for this study consist of students in one private university. This study employs a quantitative method. A set of questionnaire survey was administered online with a return of 367 respondents. The research data was analyzed using Structural Equation Modelling (SEM) and Smart PLS. The findings gathered indicate that self-regulation, students' sense of isolation and lack of learning resources significantly impact their intention to effectively use e-learning methods. It is thus evident that students’ intention to learn effectively must be supported by factors outside of themselves, to keep them highly motivated, disciplined, as well as proactive through self-directed learning.

Background: Hernia repair is most common surgical procedure in a surgical setting.Ventral hernias are defined as non-inguinal, no hiatal defect in abdominal wall fascia.Abdominal binders are usually recommended in routine after repair of ventral hernias.Abdominal binder is a belt which is wide enough to surrounds the abdominal region and supports the wound. Findings reported in previous studies are better with binders.
Objective: To compare the outcome of binder use versus no abdominal binder use after ventral abdominal wall hernia repair
Material & methods: This Randomized Controlled Trial was done at Department of Surgery, Central Park Teaching Hospital Lahore for 6 months. Sixty patients were included and underwent ventral hernia repair under general anesthesia. Then patients were randomly divided in two groups. Group A for Abdominal Binder and Group B for without Abdominal Binder by using lottery method. During 6 weeks, patients were followed-up in OPD fortnightly. Patient were evaluated for pain, Pulmonary Function Assessment on spirometer, Physical Function Assessment by 6 minutes’ walk test, Seroma formation assessment, wound infection, wound dehiscence and patients satisfaction.Data was analyzed in SPSS version 20.
Results: In this study, the mean age of patients was 42.36±8.52years in binder group while 45.11±10.22years in non-binder group. There were 12 males and 18 females in binder group while 16 males and 14 females in non-binder group. At the end of study, the mean pain score was 0.0±0.0 in binder group while 0.7±0.1 in non-binder group (p<0.05), the mean FEV1 was 90.21±6.39 in binder group while 89.91±12.30 in non-binder group (p>0.05) and the mean 6MWT was 559.49±52.10m in binder group while 514.79±42.39m in non-binder group (p<0.05). Seroma formation occur in 2 (6.7%) cases in binder group while in 8 (26.7%) in non-binder group (p<0.05). Wound infection occurred in 1 (3.3%) in binder group while in 6 (20%) cases of non-binder group (p<0.05) While wound dehiscence was not observed in any case in binder group (0%) but in 2 (6.7%) cases in non-binder group (p>0.05).
Conclusion: Thus results of this study showed that abdominal binder can help to improve the physical condition as well as can well manage wound.
