Authors: Tanamas Gregorius , Iskandar Jasmine , Utami Tofan W , Anggraeni Tricia D , Nuryanto Kartiwa H 
Published: May 2019

Objective: To evaluate Risk of Malignancy Index (RMI) as a triage tool for ovarian cancer in Dr. Cipto Mangunkusumo Hospital.
Method: This is a retrospective study conducted from January 2008-December 2012 in patients diagnosed with ovarian mass. Patients admitted for surgery due to ovarian masses were included to this study. RMI 3 score was calculated based on ultrasonography examination in Dr. Cipto Mangunkusumo Hospital, CA-125 test and menopausal status. Patients without final pathological report and incomplete data were excluded from study. Data were analysed using SPSS 20 to evaluate RMI result and final pathlogical report in benign and malignant case.
Result: From 882 patients identified with ovarian masses from cancer registry, only 99 patients aged 17-70 y.o were included in this study. Most of the patients were nully-parity (28.3%), non-menopausal women (60.6%), normal body mass index (40.4%), and with stage IIIC ovarian cancer (33.3%). Ultrasonography examination showed that most of patients had solid mass and ascites (19.2%). Meanwhile, CA-125 showed that patients with <35 U/ml were 10.1% and ≥ 35 U/ml were 89.9%. Patients with RMI scores <200 (benign cases) were 19 cases (19.2%) and ≥ 200 (malignant cases) were 80 cases (80.8%). Meanwhile, patients with benign final pathological report were 23 cases (23.2%) and malignant cases were 76 cases (76.8%). There was no statistical difference in RMI between benign and malignant cases based on final pathological report.
Conclusion: Our study showed that RMI was not accurate as triage tool for ovarian cancer in our hospital. Further investigation and more patients are needed to confirm this study.
Keywords: CA-125, menopausal status, ovarian cancer, risk of malignancy index (RMI), ultrasonography.

Actualité de la forêt normande
Authors: Aubert Pierre 
Published: May 2019

«Rien ne s'accomplit que dans la durée, rien ne s'acquiert que par la patience, tout se perd par la turbulence.»
Cette affirmation prononcée par M. le Président de la République lors de la célébration du centenaire de «Sciences Po» s'appliquerait tout particulièrement à la forêt ; nul n'ignore en effet que celle-ci est un ensemble vivant complexe lié à beaucoup de passé et gros d'avenir lointain. Durée, patience, solidarité entre les générations en même temps qu'imagination et hardiesse sont les exigences d'une bonne gestion de la forêt ; les futaies, parce qu'elles sont centenaires, portent en elles l'empreinte des heurs et malheurs des époques qu'elles ont traversées.
Présenter la forêt normande telle qu'elle s'offre à nous aujourd'hui oblige donc à porter son regard en arrière dans le temps, puis à saisir le contexte du moment présent pour le dominer et préparer la forêt aux services que demain lui demandera.
Evreux les problèmes de croissance d’une ville moyenne
Authors: El Kamal Jean 
Published: May 2019

Jusque-là traditionnelle ville d'administration et de commerce, l'agglomération d'Evreux, doublant sa population en deux décennies, s'est engagée dans un assez remarquable processus de croissance.
Les activités tertiaires assurent leur prépondérance en s'appuyant sur l'action conjuguée du renforcement des services publics et des effets de rattrapage en matière d'équipement, relayés par la montée des niveaux de consommation, illustration à l'échelle locale des modalités du développement national.
L'industrialisation par son rythme d'expansion rapide a été un moteur non moins efficace du dynamisme urbain. Du fait de sa proximité de la capitale et de la mise en œuvre de structures d'accueil favorables, la ville a pleinement profité de la décentralisation industrielle ; parallèlement, elle s'insère dans un système économique de dimension nationale très dépendant du centre de décision parisien.
La progression de l'emploi ne s'est pas toutefois accompagnée de l'élargissement souhaitable du marché du travail. Les difficultés d'intégration sociale des nouveaux citadins sont assez sensibles, en partie suscitées par les déséquilibres spatiaux résultant de l'extension de l'organisme urbain.
Par ses réussites et ses aspects contraignants, l'évolution récente d'Evreux illustre la problématique des villes moyennes françaises.
La pénétration étrangère dans l'industrie haut-normande
Authors: Concato Francis , Thuillier Jean-Pierre 
Published: May 2019

Le présent article vise à fournir une image de la situation des entreprises à participation étrangère dans l'industrie de la Haute-Normandie, à partir des statistiques actuellement disponibles. L'hétérogénéité des données (liées à la dualité des sources d'information) et les difficultés méthodologiques inhérentes à la perception de la pénétration étrangère doivent inciter à la circonspection dans l'analyse du phénomène sous examen.
Sous ces réserves, trois conclusions essentielles se dégagent de cette étude. En premier lieu, l'industrie haut-normande constitue un pôle d'attraction de premier plan pour les entreprises étrangères. En second lieu, si l'on considère les origines nationales des capitaux investis, on s'aperçoit que la situation de la Haute-Normandie ne diffère pas sensiblement de celle de l'industrie nationale. A cet égard, l'effet de proximité n'y joue pas un rôle aussi éminent qu'en d'autres régions (Alsace, Lorraine, Nord). Enfin, par le canal des participations en cascade, le capital étranger s'insère dans l'ensemble du tissu industriel régional ; contrairement à une idée trop largement répandue, les petites entreprises industrielles n'échappent pas à la pénétration étrangère, témoignant ainsi du fonctionnement capillaire du capitalisme international.
La participation des entreprises au financement de la formation professionnelle continue : l'exemple de la Haute-Normandie
Authors: Silvestri Ubald , Ribardière Gilles 
Published: May 2019

The results of vocational training, financed by the managers are given by statistical data drawn from their declarations sent to the taxes office in the local district where the enterprise is registered. The article tries to analyse these results in Haute-Normandie in a double aim : to point out the main lines of the local development of vocational training compared with the French one, between 1972-78 ; to show and correct, for the year 1977, problems which, because of the data system, bring to an important under-evaluation of what really happens in matter of vocational training specially inside medium and big enterprises.
This correction gives a better approach to vocational training in Haute-Normandie, but not quite perfect as it is quoted in the conclusion.
Exploring the Age-dependent Properties of M and L Dwarfs Using Gaia and SDSS

Published: May 2019

Abstract
We present a sample of 74,216 M and L dwarfs constructed from two existing catalogs of cool dwarfs spectroscopically identified in the Sloan Digital Sky Survey (SDSS). We cross-matched the SDSS catalog with Gaia DR2 to obtain parallaxes and proper motions and modified the quality cuts suggested by the Gaia Collaboration to make them suitable for late-M and L dwarfs. We also provide relations between Gaia colors and absolute magnitudes with spectral type and conclude that (G −

) has the tightest relation to spectral type for M and L dwarfs. In addition, we study magnetic activity as a function of position on the color–magnitude diagram, finding that Hα magnetically active stars have, on average, redder colors and/or brighter magnitudes than inactive stars. This effect cannot be explained by youth alone and might indicate that active stars are magnetically inflated, binaries, and/or high metallicity. Moreover, we find that vertical velocity and vertical action dispersion are correlated with Hα emission, confirming that these two parameters are age indicators. We also find that stars below the main sequence have high tangential velocity, which is consistent with a low metallicity and old population of stars that belong to the halo or thick disk.
The Physical Nature of Spiral Wave Patterns in Sunspots
Authors: Kang Juhyung , Chae Jongchul , Nakariakov Valery M. , Cho Kyuhyoun , Kwak Hannah , Lee Kyeore 
Published: May 2019

Abstract
Recently, spiral wave patterns (SWPs) have been detected in 3 minute oscillations of sunspot umbrae, but the nature of this phenomenon has remained elusive. We present a theoretical model that interprets the observed SWPs as the superposition of two different azimuthal modes of slow magnetoacoustic waves driven below the surface in an untwisted and non-rotating magnetic cylinder. We apply this model to SWPs of the line-of-sight (LOS) velocity in a pore observed by the Fast Imaging Solar Spectrograph installed at the 1.6 m Goode Solar Telescope. One- and two-armed SWPs were identified in instantaneous amplitudes of LOS Doppler velocity maps of 3 minute oscillations. The associated oscillation periods are about 160 s, and the durations are about 5 minutes. In our theoretical model, the observed spiral structures are explained by the superposition of non-zero azimuthal modes driven 1600 km below the photosphere in the pore. The one-armed SWP is produced by the slow-body sausage (m = 0) and kink (m = 1) modes, and the two-armed SWP is formed by the slow-body sausage (m = 0) and fluting (m = 2) modes of the magnetic flux tube forming the pore.
X-Ray Timing Studies of the Low-field Magnetar CXOU J164710.2–455216
Authors: An Hongjun , Archibald Robert 
Published: May 2019

Abstract
We report results of X-ray timing analyses for the low-field magnetar CXOU J164710.2−455216, which exhibited multiple outbursts. We use data taken with NICER, NuSTAR, Chandra, and Neil-Gehrels-Swift telescopes between 2017 and 2018 when the source was in an active state. We perform semi-phase-coherent timing analyses to measure the spin parameters and a spin-inferred magnetic-field strength (B

s
) of the magnetar. Using a semi-phase-coherent method, we infer the magnetic-field strengths to be (3–4) × 1013 G at the observation period (∼MJD 58000), and by comparing with previous frequency measurements (MJD 54000) a long-term average value of B

s
is estimated to be ≈4 × 1013 G. So this analysis may add CXOU J164710.2−455216 to the ranks of low-field magnetars. The inferred characteristic age (τ

c
) is 1–2 Myr, which is smaller than the age of Westerlund 1, so the magnetar’s association with the star cluster is still secure. For the low dipole field and the large age, recent multiple outbursts observed from the source are hard to explain unless it has strong magnetic multipole components. We also find timing anomalies around outburst epochs, which suggests that there may be spindown torque applied to the magnetar near the epochs as was proposed in magnetar models.

We have investigated the distributions of stellar azimuthal and radial velocity components V

Z
across the Galactic disk of 6.34 ≲ R ≲ 12.34 kpc and

using a Gaia and Gaia-LAMOST sample of stars. As found in previous works, the distributions exhibit significant spiral patterns. The V

R
distributions also show clear quadrupole patterns, which are the consequence of the well-known tilt of the velocity ellipsoid. The observed spiral and quadrupole patterns in the phase space plane vary strongly with radial and azimuthal positions. The phase spirals of V
Φ become more and more relaxed as R increases. The spiral patterns of V
Φ and V

R
and the quadrupole patterns of V

R
are strongest at −2° < Φ < 2° but negligible at 4° < Φ < 6° and −6° < Φ < −4°. Our results suggest an external origin of the phase spirals. In this scenario, the intruder, most likely the previously well-known Sagittarius dwarf galaxy, passed through the Galactic plane in the direction toward either Galactic center or anti-center. The azimuthal variations of the phase spirals also help us constrain the passage duration of the intruder. A detailed model is required to reproduce the observed radial and azimuthal variations of the phase spirals of V

Published: May 2019

Trichomoniasis is a curable sexually transmitted infection (STI) that has been reported to be linked to exposure to human immunodeficiency virus (HIV), although few studies have described this association. The purpose of this study was to focus on the incidence of trichomoniasis in low-income women, its relation to HIV status, viral load levels and TCD4+ cell counts, among other risk factors, using an in vitro culture as a diagnostic test. A crosssectional study among 267 women (103 HIV-positive and 164 HIV-negative) was conducted in 2015. The overall prevalence of Trichomonas vaginalis (TV) infection was 6.4%. Among HIVpositive and HIV-negative women, the prevalence was 3.9% and 7.9%, respectively, yet these results were not statistically different (p=0.1878). The factors associated with TV infection were cigarette smoking (OR= 3.52), vaginal itching (OR=4.43) and bacterial vaginosis (BV) (OR= 5.29). HIV status, TCD4+ cell count and viral load were not associated with TV infection in this group. The prevalence rates found, lower than those observed in other studies, may be due to the fact that the women evaluated in the present study are part of a low-risk populationas well as the limited sample size of HIV positive women.

O artigo é parte das construções teóricas e intervenções práticas realizadas em pesquisa qualitativa, que teve como propósito compreender como o uso das tecnologias digitais pode contribuir na construção do conhecimento geográfico dos estudantes do Ensino Médio, de modo a estimulá-los ao protagonismo juvenil. Os trabalhos foram orientados com base na seguinte problemática: Qual é o potencial existente no uso das tecnologias digitais da informação e comunicação para a construção do conhecimento geográfico no Ensino Médio com vistas ao estímulo do protagonismo social do jovem? Essa problemática foi delineada a partir da visão de que muitas vezes as disciplinas escolares parecem estar desconectadas do cotidiano dos estudantes. A pesquisa de caráter exploratório teve como procedimento o estudo de casos múltiplos, onde trabalhou-se com três professores de Geografia e suas respectivas turmas, totalizando sessenta estudantes. As atividades práticas da pesquisa foram conduzidas sob o método sala de aula invertida, com uso intensivo das tecnologias digitais. Com a realização da atividade constata-se que o uso das tecnologias digitais nas aulas proporciona maior envolvimento do estudante com o conteúdo e também estimula o protagonismo juvenil. Por outro lado, evidencia a necessidade da utilização de metodologias específicas para estas aulas, pois do contrário é grande a possibilidade de compreensão das tecnologias digitais apenas como mudança de suporte para desenvolvimento das atividades de aula.
Effect of photoelectrochemical etching and post-metallization annealing on gate controllability of AlGaN/GaN high electron mobility transistors
Authors: Uemura Keisuke , Deki Manato , Honda Yoshio , Amano Hiroshi , Sato Taketomo 
Published: May 2019

Abstract
Recessed-gate AlGaN/GaN metal–insulator–semiconductor (MIS) high electron mobility transistors (HEMTs) were fabricated by utilizing a photoelectrochemical (PEC) etching and a post-metallization annealing (PMA) process. In order to demonstrate the device performance and reliability, both electrical and optical electroluminescence (EL) properties were evaluated. The capacitance–voltage (C–V) characteristic showed that the PEC etching and subsequent PMA process enhanced the gate control of two-dimensional electron gas density. The PEC-etched-gate AlGaN/GaN MIS-HEMT showed the smallest sub-threshold slope of all the samples including planar-gate and inductively coupled plasma-etched-gate devices. Furthermore, the PEC-etched devices showed an extremely low 10−11 A mm−1 gate leakage current with no spot-like EL. These results indicated that the PEC etching and subsequent PMA process improved the electrical properties of the Al2O3/AlGaN interface, resulting in enhanced device performance of the AlGaN/GaN MIS-HEMTs.
Candiduria in hospitalized patients: an investigation with the Sysmex UF-1000i urine analyzer
Authors: He Zhengxin , Liu Yanli , Wang Tingting , Cheng Yan , Chen Jing , Wang Fukun 
Published: May 2019

Background
Candiduria is common in hospitalized patients. Its management is limited because of inadequate understanding. Previous epidemiological studies based on culture assay have been limited to small study populations. Therefore, data collected by automated systems from a large target population are necessary for more comprehensive understanding of candiduria in hospitalized patients.

Methods
To determine the performance of the Sysmex UF-1000i in detecting candiduria, a cross-sectional study was designed and conducted. A total of 203 yeast-like cell (YLC)-positive and 127 negative samples were randomly chosen and subjected to microbiologic analysis. The receiver operating characteristic curve (ROC) was used to evaluate the ability of YLC counts as measured by the Sysmex UF1000i to predict candiduria. Urinalysis data from 31,648 hospitalized patients were retrospectively investigated, and statistical analysis was applied to the data collected.

Results
Using a cutoff value of 84.6 YLCs/µL, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the yeast like cell (YLC) counts to predict candiduria were 61.7%, 84.1%, 88.6% and 66.3%, respectively. C. glabrata (33.6%) and C. tropicalis (31.4%) were more prevalent than C. albicans (24.3%) in the present study. Of the investigated hospitalized patients, 509 (1.61%) were considered candiduria-positive. Age, gender and basic condition were associated with candiduria in hospitalized patients. In the ICU setting, urinary catheterization appeared to be the only independent risk factor contributing to candiduria according to our investigation. Although antibiotic therapy has been reported to be a very important risk factor, we could not confirm its significance in ICU candiduria patients because of excessive antibiotic usage in our hospital.

Conclusions
The YLC measured by Sysmex UF-1000i is a practical and convenient tool for clinical candiduria screening prior to microbiologic culture. Candiduria is common in hospitalized patients, and its incidence varies according to age, gender and the wards where it is isolated. Candiduria had no direct connection with mortality but might be considered a marker of seriously ill patients who need particular attention in the clinic.
