Authors: Sharma Shivani , Verma Sanjeev , Kumar Vinay , Verma Raj Kumar , Singh Satinder Pal 
Published: May 2023

Objectives:
The objectives of this study were to compare the alignment efficacy, changes in arch dimensions, and pain experience with three different nickel-titanium (NiTi) archwires.

Material and Methods:
Forty-five subjects were subjected to indirect bonding in the mandibular arch, and allocated to three groups using block randomization; Group 1 (0.014” Superelastic NiTi), Group 2 (0.014” 27° Copper NiTi), and Group 3 (0.016” seven stranded coaxial NiTi archwire). The mandibular study models were retrieved periodically at 4-week intervals for 12 weeks, which were blinded to measure the change in Little’s irregularity index (LII) and dental arch dimensions. Pain and discomfort were recorded with visual analog scale at five different time intervals, namely, immediately after bonding (0) and at 1-, 4-, 8-, and 12-h for initial 7 days. Repeated analysis of variance, Wilcoxon Signed-Rank test, post hoc Bonferroni test, and Friedman’s test was applied for the comparison and was used for data analysis.

Results:
A significant reduction of LII score and increase inarch length, intercanine, interpremolar, and intermolar width (P ≤ 0.001) were observed after 12 weeks among all groups. However, intergroup comparison showed significant mean changes only for intercanine width (Group 1 versus 3) and interpremolar width (Groups 1 and 3; Groups 2 and 3). All other variables were found to be insignificant at all-time intervals when compared among each group. The increase in pain score was maximum with Group 1and least with Group 3.

Conclusion:
All archwires were found to be effective in reducing the LII score. Nevertheless, Group 3 archwire could achieve reduction of LII to zero in 14% of subjects than Groups 1 and 2.
Evaluation and correlation of nociceptive response index and spectral entropy indices as monitors of nociception in anesthetized patients
Authors: Ajayan Neeraja , Hrishi Ajay Prasad , Mathew Oommen , Saravanan Gourinandan 
Published: May 2023

Objectives:
During anesthesia, the response to these stimuli depends on the balance between nociception and antinociception. Recently, various monitoring systems based on the variables derived from electroencephalography, plethysmography, autonomic tone, reflex pathways, and composite algorithms have been introduced for monitoring nociception. The main aim of our study was to evaluate and correlate the physiological variables which reflect the autonomic nervous system response to nociception, such as heart rate (HR), systolic blood pressure (SBP), perfusion index (PI), and nociceptive response index (NRI), with the spectral entropy indices response entropy (RE) and RE-state entropy (SE), which reflects electromyographic (EMG) activation as a response to pain.

Materials and Methods:
This is a retrospective analysis of the data from a prospective study on the hypnotic and analgesic effects and the recovery profile of sevoflurane-based general anesthesia. Eighty-six patients undergoing single-agent sevoflurane anesthesia were recruited in the study. The study parameters, HR, SBP, SE, RE, RE-SE, PI, and NRI, were recorded at predefined time points before and after a standardized noxious stimulus. Correlation between the variables was carried out by applying the Pearson correlation equation for normal and the Spearman correlation equation for non-normally distributed data. Receiver operating characteristic (ROC) graphs were plotted, and the area under the curve was calculated to assess the diagnostic accuracy of post-stimulus NRI in detecting pain which was defined as RE-SE >10.

Results:
There was a significant increase in the SBP, HR, NRI, RE, SE, and RE-SE and a considerable decrease in PI values during the post-noxious period compared to the pre-noxious period. There was no correlation between the absolute values of NRI and entropy indices at T2. However, among the reaction values, there was a weak correlation between the reaction values of NRI and RE (r = 0.30; P = 0.05). The area under the ROC curve for NRI to detect pain as defined by RE-SE >10 was 0.56.

Conclusion:
During sevoflurane anesthesia, the application of noxious stimulus causes significant changes in variables reflecting sympathetic response and EMG activity. However, NRI failed to detect nociception, and there was only a weak correlation between the reaction values of NRI and RE-SE.

Authors: James Arya , George Sandhya , Shanimole Puthenpurayil Ebrahimkutty 
Published: May 2023

Objectives:
To evaluate the clinical and bacteriological profile and antibiotic susceptibility pattern in primary pyodermas.

Materials and Methods:
A descriptive cross-sectional study was carried out in patients with clinically diagnosed primary pyodermas and who attended the outpatient department of dermatology of a tertiary care center in South India from December 2017 to June 2019.

Results:
During the study period, 180 patients received a clinical diagnosis of primary pyoderma. Most common clinical type was impetigo followed by folliculitis. Most common age group affected was children below ten years of age (74 cases, 41.1%). Sixty five patients (36.1%) had lesions confined to lower limbs. Among the study participants, 26 (14.4%) were on prolonged treatment with systemic corticosteroids. Gram stain study helped in the diagnosis in 115 (63.9%) patients. Staphylococcus aureus (S. aureus) was the predominant pathogen (92 cases, 51.1%). A significant proportion of S. aureus isolates showed resistance to penicillin (90/92, 97.8%) and erythromycin (36/92, 39.1%). The pathogen isolated was methicillin resistant S. aureus (MRSA) in 28 cases (28/92, 30.4%). All isolates of Group A Streptococcus were sensitive to penicillins and first generation cephalosporins.

Limitations:
It was a single center study, conducted in a tertiary referral hospital; hence did not reflect the status of the disease in the community. Complete information on prior antibiotic treatment was not available in all patients.

Conclusion:
Pyodermas showed a predilection for younger age group. Impetigo was the leading primary pyoderma. Gram stain is a valuable, but an often neglected tool to diagnose a bacterial infection. Many isolates of S. aureus showing resistance to penicillin and erythromycin and identification of MRSA as the pathogen in many patients highlight the need for periodic assessment of pathogens and drug susceptibility patterns in different population groups to ensure judicious use of antibiotics.
Ikhsaka Banu's reconciliation and resistance to the traumatic discourse of postcolonial subjects
Authors: Sanjaya Angga Trio , Wei Zhang 
Published: May 2023

The discourse of colonial and colonized conflicts is oriented in the form of resentment and hatred of the colonized community as part of the causality of traumatic events. The wounds of the past are then passed down through the concept of memory transmission both by famillial mechanism memory and affillial memory by first-generation to post-generation. It is this hereditary traumatic condition that contributes to maintaining the discourse of inferiority and binaryism between East and West. Thus, the purpose of this study is to describe the conflicts of colonizers and postcolonial colonizers as well as examine the efforts of Iksaka Banu to release these traumatic shackles through reconciliation and resistance efforts. This research method uses Teun van Critical Discourse Analysis (AWK). Dijk which is based on the analysis of the text dimension, the social cognition dimension, and the social context dimension. Data collection techniques in this study apply listening methods and advanced recording techniques, and document review techniques. The results showed that (1) A review of the dimensions of the text showed a reconstruction of the ambivalence and traumatic of Western subjects in the short stories of Iksaka Banu; (2) A study of the dimensions of social cognition shows that the reconstruction pattern of ambivalence and traumatic of the Western subject is used as Iksaka Banu's strategy to carry out traumatic reconciliation of colonized subjects as well as resistance to Western domination and hegemony; (3) A study of the social context shows two findings of the problem, First, the existence of social inequality over the mechanisms of Western domination and hegemony; Second, even so, Indonesian society is still confined by the problem of trauma while awareness of the subject's position on the condition of social reality cannot be managed as a potential resistance

Kecerdasan logis matematis ialah kemampuan perhitungan matematis, melakukan penyelesaian masalah dengan berpikir logis dan bernalar, serta memiliki ketajaman terkait pola-pola dan hubungan-hubungan. Tingkatan kecerdasan logis matematis terbagi menjadi 3, dimana ketiga tingkat kecerdasan logis matematis dapat mempengaruhi perbedaan miskonsepsi yang dialami peserta didik saat memecahkan masalah. Miskonsepsi sendiri merupakan suatu pemahaman konsep yang tidak sejalan dengan pemahaman konsep yang dikemukakan para ahli dan sistem persamaan linear dua variabel merupakan salah satu materi yang sering mengalami miskonsepsi. Penelitian ini penelitian deskriptif kualitatif dengan tujuan memberi deskripsi miskonsepsi peserta didik pada materi SPLDV ditinjau dari tingkat kecerdasan logis sistematis. Pedoman wawancara, tes miskonsepsi, serta tes kecerdasan logis matematis menjadi instrumen pada penelitian ini. Subjek penelitian yang terpilih terdiri dari satu orang dengan kecerdasan logis matematis rendah, satu orang sedang, serta satu orang tinggi. Hasil dari penelitian ini adalah peserta didik dengan kecerdasan logis matematis tingkat tinggi dan sedang mengalami miskonsepsi ketika mengaplikasikan metode penyelesaian SPLDV menggunakan metode eliminasi. Akan tetapi, peserta didik dengan kecerdasan logis matematis tingkat rendah mengalami miskonsepsi ketika menuliskan model matematika dalam menentukan nilai konstanta. Hasil penelitian ini harapannya bisa menjadi evaluasi guru guna memberi perhatian lebih mengenai pemahaman peserta didik terkait konsep penulisan model matematika SPLDV dan pengaplikasian metode penyelesaian SPLDV seperti gabungan, substitusi, elimisasi, atau metode grafik.

Authors: Yanuarisma Annisa , Rahaju Endah Budi 
Published: May 2023

Self efficacy siswa terbagi atas self efficacy tinggi dan rendah. Hal ini menjadi salah satu faktor yang memengaruhi perbedaan proses berpikir siswa saat memecahan masalah matematika. Penelitian deskriptif kualitatif ini bertujuan untuk menjelaskan bagaimana proses berpikir siswa self efficacy tinggi dan rendah dalam memecahkan masalah matematika. Peneliti memilih dua siswa untuk dijadikan subjek penelitian yaitu seorang siswa self efficacy tinggi dan seorang siswa self efficacy rendah dengan kriteria memiliki jenis kelamin sama, kemampuan matematikanya setara, serta lancar dan terbuka dalam berkomunikasi lisan. Instrumen yang digunakan adalah lembar angket skala self efficacy, lembar Tes Pemecahan Masalah, Pedoman Wawancara, dan lembar Tes Kemampuan Matematika. Penelitian ini memperlihatkan hasil bahwa pada setiap tahap baik siswa self efficacy tinggi maupun rendah memiliki kemiripan proses berpikir karena mampu memahami masalah, merencanakan dan melakukan pemecahan masalah serta mengecek kembali hasilnya. Namun siswa self efficacy rendah masih kurang dalam hal pengidentifikasian informasi pada masalah meskipun menghabiskan waktu baca lebih banyak, tidak mempunyai dasar yang jelas dalam hal menganalisis konsep dan rumus yang sesuai untuk memecahkan masalah, kurang teliti ketika memecahkan masalah, serta melakukan pengecekan kembali jawabannya hanya pada hasil operasi hitung yang sudah dilakukan. Sedangkan siswa self efficacy tinggi cenderung tidak memeriksa kembali jawabannya namun menyertakan pembuktian tambahan. Temuan penelitian ini memiliki beberapa implikasi, salah satunya adalah guru perlu mengetahui proses berpikir siswanya ketika memecahkan masalah matematika untuk mengidentifikasi kesulitan siswa dan menggunakannya sebagai bahan evaluasi untuk merancang pembelajaran yang lebih baik di masa mendatang.
