Authors: Harianto Harianto , Eddy Hadryan 
Published: March 2021

Transaksi penjualan barang pada sebuah perusahaan terjadi setiap hari mengakibatkan semakin bertambah banyaknya catatan transaksi penjualan. Tidak banyak dari perusahaan menjadikan transaksi penjualan itu hanya sebagai arsip belaka. Yang pada akhirnya mengakibatkan sebuah perusahaan mengalami kekurangan stok barang. Tentunya hal demikian terjadi karena transaksi penjualan barang tidak dianalisa dan dipelajari polanya.
Ada beberapa banyak metode data mining yang digunakan untuk menganalisa pola pembelian barang secara bersamaan oleh pembeli. Diantara metode yang sering sekali digunakan adalah Apriori dan FP-Growth. Pada penelitian ini, bertujuan untuk menemukan pola pembelian barang secara bersamaan berdasarkan bulan selama satu tahun. Untuk menemukan pola pembelian tersebut digunakan Algoritma Apriori dan FP-Growth kemudian membandingkan hasil dalam menemukan pola kombinasi yang dihasilkan dalam dataset. Hasil dari penelitian ini algoritma Apriori membutuhkan waktu yang lebih sedikit dalam memperoses dan menampilkan hasil tapi rules yang didapatkan lebih sedikit dibandinkan algoritma FP-Growth. Sedangkan algoritma FP- Growth membutuhkan waktu yang lebih lama dbandingkan algoritma Apriori tapi menghasilkan rules yang lebih banyak dibandingkan algoritma Apriori.

Small-scale Dynamo in Supernova-driven Interstellar Turbulence
Authors: Gent Frederick A. , Mac Low Mordecai-Mark , Käpylä Maarit J. , Singh Nishant K. 
Published: March 2021

Abstract
Magnetic fields grow quickly even at early cosmological times, suggesting the action of a small-scale dynamo (SSD) in the interstellar medium of galaxies. Many studies have focused on idealized turbulent driving of the SSD. Here we simulate more realistic supernova-driven turbulence to determine whether it can drive an SSD. Magnetic field growth occurring in our models appears inconsistent with simple tangling of magnetic fields, but consistent with SSD action, reproducing and confirming models by Balsara et al. that did not include physical resistivity η. We vary η, as well as the numerical resolution and supernova rate,

, to delineate the regime in which an SSD occurs. For a given

we find convergence for SSD growth rate with resolution of a parsec. For

, with

the solar neighborhood rate, the critical resistivity below which an SSD occurs is

, and this increases with the supernova rate. Across the modeled range of 0.5–4 pc resolution we find that for

, the SSD saturates at about 5% of kinetic energy equipartition, independent of growth rate. In the range

growth rate increases with

. SSDs in the supernova-driven interstellar medium commonly exhibit erratic growth.
Le macronisme et la tradition libérale
Authors: Revault d’Allonnes Myriam , Sarthou-Lajus Nathalie 
Published: March 2021

Dans son dernier essai sur L’esprit du macronisme , la philosophe Myriam Revault d’Allonnes s’interroge sur les liens entre le macronisme et la tradition libérale, l’héritage des Lumières, auquel Emmanuel Macron se réfère. Elle montre comment certains concepts comme l’autonomie, la responsabilité, l’homme capable, qui se sont développés à partir de la modernité, ont été dévoyés par ce qu’elle appelle « la nébuleuse néolibérale » dominée par le modèle de l’entreprise et de la raison calculante, dont l’orientation est hyperindividualiste.

Le score de consommation alimentaire des ménages est positivement et significativement lié à l’accès des femmes à la terre et à son contrôle. Les ménages agricoles dans lesquels elles ont accès à la terre et la contrôlent ont en moyenne un score de consommation alimentaire supérieur de 15,75 par rapport à leurs homologues.
Un mini-péage sur les paiements : une solution pour financer la transition vers une économie durable
Authors: Rochet Jean-Charles 
Published: March 2021

Nous proposons la création d’une nouvelle taxe qui rapporterait suffisamment pour alléger la fiscalité du travail tout en finançant la transition énergétique. Il s’agit d’un mini-péage sur tous les mouvements de fonds entre les comptes bancaires des contribuables français, particuliers et entreprises. Ces mouvements représentent plus de 100 fois le PIB. Un péage à un taux très faible instauré sur un tel volume fournirait une recette fiscale substantielle, et ce même en tenant compte de la contraction qu’il entraînerait sur ce volume. Il serait peu coûteux à prélever et difficile à éviter. Son taux uniforme et l’absence d’exonérations le rendraient transparent et plus facile à faire accepter. Enfin, ce prélèvement serait progressif, car les ménages les plus riches « consomment » beaucoup de paiements scripturaux.
Reliability of 3 Urine Specific Gravity Meters for Measuring Brix and Urine Solutions at Different Temperatures
Authors: Wardenaar Floris , Ortega-Santos Carmen P. , Vento Kaila , Olzinski Stephanie , Olig Jason , Kavouras Stavros , Johnston Carol 
Published: March 2021

Context
Urine specific gravity (USG) should be measured at room temperature (20°C), but the temperature of the sample is not always considered.

Objective
To evaluate the effect of sample temperature on the measurement accuracy of a digital refractometer (DIG), manual optical refractometer (MAN), and hydrometer (HYD).

Design
Descriptive laboratory study.

Main Outcome Measure(s)
Urine specific gravity.

Results
Experiment 1 (24 Brix (°Bx) samples) showed that measurements via the DIG and MAN did not differ from the reference, but HYD provided lower or inconsistent values compared with °Bx and was highly correlated with °Bx solutions (r, &gt; = 0.89). The overall diagnostic ability of elevated USG cut-off values (≥1.020, ≥1.025, ≥1.030) was high for all tools (area under the curve &gt;0.92). Misclassification of samples increased from 0 to 2 at 1.020 to 1 to 3 samples at cutoffs of 1.025 and 1.030 USG. Bland-Altman analysis showed that the DIG 5°C underreported slightly without reporting bias (r = −0.344, P = .13); all other plots for the DIG, MAN, and HYD showed considerably larger underreporting at higher concentrations (r = −0.21 to −0.97 with P &gt;.02) at all temperatures. The outcomes of experiment 2 (33 fresh urine samples) using DIG 20°C as the standard demonstrated only negligible differences between the DIG and MAN at all temperatures but larger differences using the HYD.

Conclusions
All tools showed reporting bias compared with the °Bx solutions, which can affect the classification of low and high urine concentration at higher USG cutoff values, especially with a sample temperature of 37°C.
A Primary Care Approach for Oral Health Promotion Among HIV Patients
Authors: Rodrigues Anisha , Kannappan Suvetha , Sadhu Bhakti 
Published: March 2021

Background:
HIV-positive patients are at a greater risk for developing oral health problems, making them potentially susceptible to nutritional deficiencies, decreased adherence to treatment, and failure of highly active antiretroviral therapy. Their oral health needs are unmet due to a lack of awareness, social stigma, and other factors. The primary care workers (PCWs) are the first point of contact for health issues of these patients.

Aim:
The aim of the study was to assess the effectiveness of the educational intervention for the PCWs on oral health.

Materials and Methods:
This interventional pilot study was conducted at two residential centers for HIV patients in Mangalore. The participants included 15 PCWs working at these centers. An educational module was prepared as the intervention that included dental conditions that could compromise oral health, oral manifestations of HIV, and oral health care. A structured questionnaire was administered to the PCWs before the intervention, immediately after the intervention, and at 3 months. The PCWs were required to routinely examine the HIV patients for any dental or oral health problems and refer them to the dental hospital for treatment. The Statistical Package for the Social Sciences 20.0 software (Chicago. IL, USA) was used for analysis.p< 0.05 was considered statistically significant. Repeated measures analysis of variance and Chi-squared test were used for data analysis.

Results:
73% of the caretakers had no training in oral health care. Analysis of the mean scores revealed a statistically significant improvement (p < 0.05) in their knowledge and skills from 2.53 ± 1.3 to 7.57 ± 1.2. There was also a statistically significant increase in the number of referrals to the dental hospital.

Conclusion:
Educating the PCWs showed positive outcomes enabling patients' access to regular professional oral health care, thus improving their quality of life.

Published: March 2021

Background:
Traumatic dental injuries are a serious public dental health problem throughout the world. The incidence of traumatic injuries is increasing over the years. Trauma to the permanent anterior teeth is a common finding. Dental trauma is an irreversible pathology that after the occurrence is characterized by a life-long debilitating effect.

Aims and Objectives:
The aim of this study was to estimate the prevalence and assess factors related to traumatic injuries to permanent anterior teeth among 12–15-year-old children attending private and government schools in Mathura city.

Materials and Methods:
An epidemiological cross-sectional study was carried out among 1000 school children aged 12–15 years in which 500 children from both government and private schools, respectively, of five geographical zones of Mathura city were randomly selected. Children completed a questionnaire related to the history of trauma to their anterior teeth after which they were examined for type of lip coverage, Angle's molar relationship, and incisor nature of trauma sustained.

Statistical analysis:
SPSS 21 was carried out using Student's t-test (P < 0.05), Chi-square test, and Mantel–Haenszel test.

Results:
The prevalence of traumatic injuries was 8.9% and was higher among government school children compared to private school children. The boys and girls with a history of trauma were 67.4% and 32.6%, respectively. The main cause of trauma was fall in the playground (46.0%). The main reason of trauma was because of pushing (65.2%). The most predominant injuries were enamel fractures and the most common place for occurrence was school.

Conclusion:

Published: March 2021

Background:
Sickle cell disease is a common hereditary hemoglobin disorder in southern Saudi Arabia. The current models of health care provision and health service utilization are not homogeneous across the kingdom.

Aim:
The current models of health care provision and health service utilization in a single center in our region were audited to evaluate the current provided healthcare services and suggest improvement if needed.

Methodology:
In this retrospective chart review study, from 2015 to 2019, all patients with sickle cell anemia admitted to a tertiary care hospital were enrolled in the study. All related data including demographics, laboratory interventions, and management procedures were collected. Descriptive analysis and statistical tests of association were performed.

Results:
One hundred and twenty-one patients were admitted 165 times over the study period. Vaso-occlusive pain episodes was the most commonindication (58%) for admission, followed by hepatobiliary (16%), and pulmonary complications (12.7%). Most of the provisioned services were of nonspecialized medical or surgical specialties. Blood transfusion was overused (64%), whereas adequate hydroxyurea (HU) therapy was underused (25%).

Conclusion:
The current study offers a glimpse of some gaps between the current practice and the established local, national, and international guidelines in terms of underutilizing HU and over utilizing blood transfusion. Comprehensive care centers were not available, and care was provided mainly by nonhematologists. Educating health providers and establishing comprehensive care centers would enhance the current model of health care provision.
Three-dimensional ultrasound for carotid vessel wall volume measurement
Authors: Chen Ying-An , Chen Pei-Ya , Lin Shinn-Kuang 
Published: March 2021

Objectives:
The intima–media thickness (IMT) of the carotid artery can now be detected on a three-dimensional (3D) plane. The 3D vessel wall volume (VWV) more accurately represents vascular conditions. Through 3D ultrasound, we established a standardized method for carotid VWV measurement.

Materials and Methods:
A total of thirty patients without stroke or cardiovascular disease who received carotid duplex sonography were retrospectively reviewed. Gray-scale 3D images from the distal common carotid artery (CCA) to internal carotid artery on both sides were acquired using a single-sweep 3D transducer and analyzed offline by using the vascular plaque quantification function of the Philips QLAB software. Then, the 3D IMT(QLAB intima–media thickness [QIMT]), total plaque volume (TPV), and VWV were measured by a neurologist and a technician, and the interobserver variability was assessed.

Results:
The mean two-dimensional (2D) carotid IMT was 0.65 ± 0.12 mm. The mean QIMT, TPV, and VWV measured by observer 1 were 0.68 ± 0.18 mm, 26 ± 12 mm3, and 94 ± 10 mm3, respectively. The Bland–Altman plot of the mean differences between the QIMT, TPV, and VWV values measured by observers 1 and 2 showed that those of observer 2 were within two standard deviations of those of observer 1. Intraclass correlation coefficients (ICCs) indicated strong correlations in QIMT (ICC = 0.76), TPV (ICC = 0.85), and VWV (ICC = 0.90; P < 0.001) between observers 1 and 2. Both 2D IMT and 3D QIMT exhibited a positive linear correlation with age.

Conclusion:
This study established a standardized VWV measurement through 3D ultrasound. Reasonable interobserver differences were obtained within a 95% limit of agreement and high reliability (ICC = 0.90). The VWV 1 cm from the CCA bifurcation was quantified with a mean value of 94.2 mm3. Further studies on the 3D ultrasound quantification of carotid arteries are warranted.
