IMPLEMENTATION OF SMART TECHNOLOGY, ARTIFICIAL INTELLIGENCE, ROBOTICS, AND ALGORITHMS (STARA): A THREAT OR OPPORTUNITY FOR WORKERS 'FUTURE
Authors: Lestari Lela , Djastuti Indi
Published: April 2021

This qualitative phenomenological study aims to examine andcompare the perceptions of workers in the banking sector regarding theimplementation of STARA in their work. This study was conducted throughin-depth interviews with informants about perceptions regarding optimizing STARA implementation in the banking sector, in the form of bankingdigitalization in the current Industrial Revolution 4.0 era. The informantsin this study were bank employees such as the teller, customer service, andback-office personnel. Sampling was done using non-random samplingmethod with purposive sampling technique which amounted to 12 informants, consisting of four tellers, four customer service officers, and fourback-office personnel. The results of the study showed that the majority ofbank employees in frontliner positions, namely tellers, felt that their position could be replaced by the implementation of STARA. However, someinformants in the frontliner position, namely customer service, stated thatthey did not feel threatened, because they believed there was a certaincomfort when customers were served by humans rather than by machines.Meanwhile, bank employees in the back-office position have not felt anythreat due to the implementation of STARA because they feel that the analysis process cannot be fully carried out properly by a system and still requires humans. In addition, employees in the back-office position statedthat the implementation of STARA makes it easy for them to completetheir work and can be used as an opportunity to achieve work performance.The results of this study also show that overall employees have not felt adecrease in commitment to the organization, obstacles in career advancement, desire to move, cynicism, or depression when working with the implementation of STARA, which is predicted to take their jobs.

Low-level laser irradiation in the comprehensive treatment of acute renal damage
Authors: Ryazantsev V. E. , Vlasov A. P. , Mashnin I. V.
Published: April 2021

Background. The discussed topic is worth attracting attention because of its high mortality rate in patients with acute renal damage which is caused by urological and surgical diseases. The membrane-destructive component in damaged renal tissues is manifested with decreased glomerular filtration rate, increased endotoxin level and lipid aberrations. The standard infusion and antibacterial therapy does not fully compensate the severity of pathological changes.

Purpose. To study the effectiveness of low-level laser irradiation at endotoxicosis and lipid metabolism indicators in acute renal damage in acute experimental peritonitis.

Material and methods. Lipid peroxidation, membrane-destructive processes in renal tissues as well as lipid metabolism and endotoxicosis were studied in the experiment with dogs. The effectiveness of infusion and antibiotic therapy and combined therapy with laser light were compared.

Basic results: the experiment has demonstrated that acute renal damage was caused by systemic inflammatory diseases of non-urological profile. The applied low-level laser irradiation (LLLI) promoted more rapid correction of pathological processes which were manifested with increased concentration of cholesterol esters, total phospholipids, phosphatidylserine; LLLI decreased levels of cholesterol, phosphatidylcholine, triacylglycerol, phosphatidylinositol, triacylglycerol, phosphatidylinositol, diacylglycerol, lysophospholipids, free fatty acids and endotoxicosis parameters.

Conclusion: the obtained results reliably indicate a LLLI positive effect at the organism’s potentials to recover when LLLI is included into the comprehensive therapy (under experiment). This is evidently seen in the restoration of lipid component in elements of renal parenchyma and in the decrease of lipid peroxidation activity.
The influence of smoking on the functional state of microcirculation according to laser doppler flowmetry and clinical anamnestic data of patients with arterial hypertension
Authors: Streltsova N. N. , Vasiliev A. P.
Published: April 2021

Background. Detailed study of the functional state of microcirculation in combination of arterial hypertension and tobacco smoking, as the most common and prognostically important risk factors for atherogenesis, will not only clarify pathogenetic effect of tobacco smoke on the terminal vascular bed, but also outline directions of active counteraction to it.

Purpose. To study the effect of TS on the functional state of SM using laser Doppler flowmetry in patients with AH.

Methods. 185 patients with stage 1,2 AH involved in the study were divided into 2 equivalent groups according to main clinical and laboratory data: group 1 – non-smokers (n = 134, mean age was 57.0 [50.0; 60.0]), group 2 – patients who smoke 1–1.5 packs of cigarettes per day (n = 51, mean age was 54.0 [48.0; 58.0]). Patients were prescribed short-acting antihypertensives drugs, which were used whenever required 5 days before the study. SM was investigated by laser Doppler flowmetry using occlusion test and amplitude-frequency spectrum analysis of hemoperfusion fluctuations.

Results. Obtained data showed negative acute effect of ingredients of tobacco smoke on almost all structural elements of microhemocirculation. Revealed deviations are characterized by constriction of precapillary segment of microvascular bed with increase in myogenic tone and equal 3.1 units [2.6; 4.1] versus 2.3 units [1.7; 3.4] in the alternative group (p = 0.007), decrease in capillary blood flow from 4.5 units [3.5; 5.8] compared with the group of non-smokers – 5.2 units [4.0; 7.3] (p = 0.041), statistically significant intensification of arteriolar-venular blood flow with formation of venous congestion, limitation of dilated reserve of microcirculation.

Conclusion. Tobacco smoking leads to significant microcirculation disorders that are projected onto changes in terminal vascular bed, inherent with AH, which significantly reduces the functional state of microcirculation, limits its reserve potential and promotes the development of tissue ischemia.

The work carried out a comparative analysis of the results of surgical treatment of the epithelial-coccygeal course of ECC in 133 children aged 3 to 17 years, using laser-induced interstitial thermotherapy (LIT) and open excision. Comparative analysis was carried out according to the following criteria: duration of surgery, average time of hospital stay, duration of pain syndrome on a 10-point scale (VAS), the presence of complications in the early and late postoperative period. In the main group, the average time of hospital stay was 4.9 ± 0.3; the duration of surgical treatment was 17.2 ± 2.8 minutes. The duration of the pain syndrome was 5.3 ± 2.1 hours, and its severity was 2.7 ± 0.8 points. Average terms of epithelialization of fistulas are 3.1 ± 2.8 days. Recurrence of ECC was observed in 7 patients (11.7%), which required re-intervention. In 3 (5.0%) patients, LIT was used, and in 4 (6.7%), excision using plastics according to the Bascom method. In the comparison group, the duration of surgical treatment was 32.6 ± 5.4 minutes. The duration of inpatient treatment is 16.7 ± 1.4 days. Pain syndrome averaged 71.8 ± 11.9 hours, severity 6.5 ± 2.3 points. The number of relapses was 9 (12.3%), of which 5 (6.8%) children underwent laser treatment, and 4 (5.5%) repeated surgical excision with Bascom with recovery. This technique is an effective and minimally invasive method for treating ECC, which makes it possible to recommend this method for use in pediatric surgical practice.

Many people expect a good, healthy, prosperous life, do not experience suffering. People who have a prosperous, healthy life, without suffering are usually identified with people who are obedient and fear God, where the concept of fearing God gets blessings and does not get curses, suffering, or other bad things that are often referred to as the principle of retaliation. This principle of retaliation is a common and believed principle from time to time. In wisdom literature, the principle of retaliation is one of the points that need attention. But in fact there are many who are pious, fearing God, whether they experience suffering that is not appropriate. This research approach is qualitative using a theological approach that can be used to understand the gaps that occur, collect data from various literary sources that can be used to collect the material needed, such as books in libraries, Junarl, the web, electronic mass media, etc. . the concept of the principle of retribution cannot be established in general terms and can be stated inaccurately if it is addressed to righteous people, pious people, good people, and suffering children, because the theory stated by the facts that occurs is incompatible and very contradictory.
Teologi Penggembalaan Yehezkiel Dalam Menghadapi Tantangan Kehidupan Jemaat
Authors: Simanjuntak Linda Zenita , Abdi Hu Samuel , Aziz Lukgimin
Published: April 2021

Artikel ini berangkat dari gagasan tentang fakta di berbagai belahan dunia, khususnya segmen penggembalaan dalam teologi Kristen. Sebagai sebuah nubuatan, tentunya nabi Yehezkiel memiliki banyak pesan penting bagi kehidupan para Gembala saat itu. Yehezkiel 34 sebagai salah satu bagian nubuat yang krusial bagi para pembaca saat ini, khususnya bidang teologi praktis patut untuk dikaji guna memperoleh tuntunan yang bermakna bagi para Gembala Jemaat dalam menggembalakan sekelompok orang yang menghadapi berbagai tantangan dalam hidup. Berbagai tantangan tersebut semakin pelik ketika pandemi corona dideklarasikan pada awal tahun 2020. Dengan menggunakan metode studi pustaka, peneliti menggali berbagai karya sastra untuk menjawab kebutuhan di lapangan, khususnya teologi pastoral sebagai bagian dari teologi praktis. Hasil penelitian menyatakan bahwa semangat penggembalaan tidak boleh diredupkan oleh tantangan hidup yang semakin kompleks. Isi nubuatan dalam Yehezkiel 34 ini membahas dua bidang yang berbeda, yaitu penghakiman pengharapan di dalam Kristus. Sebagai nubuatan, Yehezkiel 34 memberi domba-domba itu harapan penuh sukacita untuk menunggu campur tangan Tuhan selama praktik penggembalaan yang menyesatkan. Di sisi lain, sebagian Gembala justru memiliki kesempatan untuk menunjukkan kekuatan dan kepemimpinan Tuhan Gembala Agung yang telah mengizinkan mereka untuk melayani. Tuhan telah memberikan alat dan kebijaksanaan bijak kepada para Pendeta untuk memimpin jemaat pada kenyamanan dan kenyamanan hidup baik secara fisik maupun spiritual.

Authors: Khalid Summra , Dan Wang , Sohail Amir , Raza Wahid , Khalid Bushra , Ur-Rehman Ahmad
Published: April 2021

Purpose – The research study aims to assess the women’s Business education and leadership training program at a higher institutional level in order to examine how the program impacts and contributes to women’s empowerment. Further, this research sought to explore women’s leadership training aspect that has not explicitly elucidated. Besides, this study looks upon women’s self-perception by empowering them with skills and leadership capabilities to change hard-core gender stereotypes in society. Research methodology – The sample size comprised of 82 enrolled female students in the training program. The qualitative statistics (i.e., three focus groups) evaluated with the Kirkpatrick model. The Wilcoxon signed-rank test was applied to compare pre-and post-training quantitative data (i.e., questionnaire). Effect size is measured to check the effectiveness of the training program. Findings – The post-training evaluation revealed higher scores in knowledge, tools, and leadership skills. The training program encouraged women to bring change in self-perception and gain confidence for transformative changes in society. Findings support the effectiveness of leadership education and training programs. Research limitations – This research conducted in a Pakistani patriarchal cultural context and one region of Pakistan (Punjab). Hence the results are carefully generalised. The long term outcomes of this leadership training program and women’s performance in the job market are not studied. Practical implications – Findings suggest that a training program positively affects women’s learning, knowledge, and behaviour. Training programs empower women with practical tools for self and business development. The program encouraged women to gain better insight into work-life challenges and enhance personal competencies to gain equal rights. Originality/Value – This research will significantly contribute to the relatively scarce literature on the effectiveness of women’s business education and leadership training programs at a higher institutional level in the Pakistani context for women empowerment.
Following Up the Kepler Field: Masses of Targets for Transit Timing and Atmospheric Characterization
Authors: Jontof-Hutter Daniel , Wolfgang Angie , Ford Eric B. , Lissauer Jack J. , Fabrycky Daniel C. , Rowe Jason F.
Published: April 2021

We identify a set of planetary systems observed by Kepler that merit transit-timing variation (TTV) analysis given the orbital periods of transiting planets, the uncertainties for their transit times, and the number of transits observed during the Kepler mission. We confirm the planetary nature of four Kepler Objects of Interest within multicandidate systems. We forward-model each of the planetary systems identified to determine which systems are likely to yield mass constraints that may be significantly improved upon with follow-up transit observations. We find projected TTVs diverge by more than 90 minutes after 6000 days in 27 systems, including 22 planets with orbital periods exceeding 25 days. Such targets would benefit the most from additional transit-timing data. TTV follow-up could push exoplanet characterization to lower masses, at greater orbital periods and at cooler equilibrium temperatures than is currently possible from the Kepler data set alone. Combining TTVs and recently revised stellar parameters, we characterize an ensemble of homogeneously selected planets and identify planets in the Kepler field with large-enough estimated transmission annuli for atmospheric characterization with James Webb Space Telescope.

We introduce the Automatic Learning for the Rapid Classification of Events (ALeRCE) broker, an astronomical alert broker designed to provide a rapid and self-consistent classification of large etendue telescope alert streams, such as that provided by the Zwicky Transient Facility (ZTF) and, in the future, the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). ALeRCE is a Chilean-led broker run by an interdisciplinary team of astronomers and engineers working to become intermediaries between survey and follow-up facilities. ALeRCE uses a pipeline that includes the real-time ingestion, aggregation, cross-matching, machine-learning (ML) classification, and visualization of the ZTF alert stream. We use two classifiers: a stamp-based classifier, designed for rapid classification, and a light curve–based classifier, which uses the multiband flux evolution to achieve a more refined classification. We describe in detail our pipeline, data products, tools, and services, which are made public for the community (see https://alerce.science). Since we began operating our real-time ML classification of the ZTF alert stream in early 2019, we have grown a large community of active users around the globe. We describe our results to date, including the real-time processing of 1.5 × 108 alerts, the stamp classification of 3.4 × 107 objects, the light-curve classification of 1.1 × 106 objects, the report of 6162 supernova candidates, and different experiments using LSST-like alert streams. Finally, we discuss the challenges ahead in going from a single stream of alerts such as ZTF to a multistream ecosystem dominated by LSST.

Published: April 2021

Recent discoveries of young exoplanets within their natal disks offer exciting opportunities to study ongoing planet formation. In particular, a planet’s mass accretion rate can be constrained by observing the accretion-induced excess emission. So far, planetary accretion is only probed by the Hα line, which is then converted to a total accretion luminosity using correlations derived for stars. However, the majority of the accretion luminosity is expected to emerge from hydrogen continuum emission, and is best measured in the ultraviolet (UV). In this paper, we present HST/WFC3/UVIS F336W (UV) and F656N (Hα) high-contrast imaging observations of PDS 70. Applying a suite of novel observational techniques, we detect the planet PDS 70 b with signal-to-noise ratios of 5.3 and 7.8 in the F336W and F656N bands, respectively. This is the first time that an exoplanet has been directly imaged in the UV. Our observed Hα flux of PDS 70 b is higher by

than the most recent published result. However, the light curve retrieved from our observations does not support greater than 30% variability in the planet’s Hα emission in six epochs over a five month timescale. We estimate a mass accretion rate of

. Hα accounts for 36% of the total accretion luminosity. Such a high proportion of energy released in line emission suggests efficient production of Hα emission in planetary accretion, and motivates using the Hα band for searches of accreting planets. These results demonstrate HST/WFC3/UVIS’s excellent high-contrast imaging performance and highlight its potential for planet formation studies.
Precise Estimation of Source Intensity for Wide-field Telescopes with PSF Modeling
Authors: Sun Rongyu , Yu Shengxian , Jia Peng
Published: April 2021

Wide-field small aperture optical telescopes are widely used in large-scale surveys currently and they have made great contributions in a number of astronomical applications. However, specific challenges arise owing to the defects caused by the optical system, and the image quality and reduction precision are negatively affected. An innovative method is proposed to address these challenges and achieve a high-precision source intensity estimation. In implementation, first a dedicated pipeline is developed to investigate the point-spread function (PSF) components from large amounts of images, using principal component analysis. Then the PSF model that reveals the actual characteristics of the optical system is constructed based on the evaluation. Last the equations for centroid and intensity estimation are constructed and the results are obtained. A trial of observations is performed with a wide-field small aperture telescope, and a large number of raw images, as well as simulated images, are acquired to test the efficiency of our method. The intensity measurement is performed with our method and other common algorithms, including the modified moment, Gaussian fitting, and SExtractor. Based on the comparison it is demonstrated that our proposed method outperforms the others. The results indicate that our method explores the limitations of such a system and additional gains can be achieved in wider applications.
Modeling Turbulence in Galactic Centers
Authors: Salas Jesus M. , Morris Mark R. , Naoz Smadar
Published: April 2021

Turbulence is a prevalent phenomenon in the interstellar medium, and in particular, the environment at the centers of galaxies. For example, detailed observations of the Milky Way’s Central Molecular Zone (CMZ) revealed that it has a complex and turbulent structure. Turbulence on galactic scales is often modeled using star formation and feedback. However, these effects do not appear to be sufficient for explaining the high-velocity dispersion observed in the CMZ, indicating that additional gas-stirring processes are likely to be operating. Here we introduce a proof-of-concept method to drive turbulence in gas that orbits under the influence of a galactic potential. Instead of relying on a particular physical mechanism, we have adopted a Fourier forcing module and have applied it using a smoothed particle hydrodynamics code. To test our method, we performed simulations of a simplistic model of the CMZ. Our turbulence injection method is capable of balancing the self-gravity of the gas, which allows us to run the simulations for long timescales and thereby follow the evolution of the CMZ. Our results show that turbulence induces a flocculent spiral pattern in our model, analogous to that found in galactic-scale simulations. Furthermore, we find that our turbulence injection method induces inward migration of gas, a result consistent with previous numerical simulations. We submit that this injection method is a promising new tool to simulate turbulence in galactic centers.
Coherent Curvature Radio Emission and Polarization from Pulsars
Authors: Gangadhara R. T. , Han J. L. , Wang P. F.
Published: April 2021

We have developed a collective plasma radio emission model for the radio pulsars based on the implications of the tangent model. The secondary pair (electron–positron) plasma particles get arranged into a phased array like an antenna due to plasma waves and radiate in phase. We have reproduced the polarization profiles by considering different viewing conditions in the pulsars having an oblique dipolar magnetic field. We find that when there is a resonance between the radio and the plasma waves, the flux of emitted radio waves gets enhanced. We numerically estimated the collective radio emission due to relativistic plasma. The model predicts the correlation between the sign reversal circular polarization and the polarization angle swing and the brightness temperature in the range ∼1031–1033 K.

M
⊙) from deep 21 cm observations and with an [O iii]/[O ii] (5007/3727) ratio of 18.3 ± 0.11, Pox 186 is a promising candidate Lyman continuum emitter. It may be a possible analog of low-mass reionization-era galaxies. We present a spatially resolved kinematic study of Pox 186 and identify two distinct ionized gas components: a broad one with σ > 400 km s−1 and a narrow one with σ < 30 km s−1. We find strikingly different morphologies between the two components and direct evidence of outflows as seen in the high-velocity gas. Possible physical mechanisms driving the creation of high-velocity gas seen in [O iii] are discussed, from outflow geometry to turbulent mixing between a hot (106 K) star-cluster wind and cooler (104 K) gas clouds. We find a modest mass-outflow rate of 0.022 M
⊙ yr−1 with a small mass-loading factor of 0.5, consistent with other low-mass galaxies. Finally, we compare the mass-loading factor of Pox 186 with extrapolations from numerical simulations and discuss possible reasons for the apparent discrepancy between them.

Asymmetry Revisited: The Effect of Dust Attenuation and Galaxy Inclination
Authors: Yuan Fang-Ting , Lu Jiafeng , Shen Shiyin , Boquien Médéric
Published: April 2021

Dust attenuation of an inclined galaxy can cause additional asymmetries in observations, even if the galaxy has a perfectly symmetric structure. Taking advantage of the integral field spectroscopic data observed by the Sloan Digital Sky Survey-IV Mapping Nearby Galaxies at the Apache Point Observatory survey, we investigate the asymmetries of the emission-line and continuum maps of star-forming disk galaxies. We define new parameters, A

a
and A

b
, to estimate the asymmetries of a galaxy about its major and minor axes, respectively. Comparing A

a
and A

b
in different inclination bins, we attempt to detect the asymmetries caused by dust. For the continuum images, we find that A

a
increases with the inclination, while A

b
is a constant as inclination changes. Similar trends are found for g − r, g − i, and r − i color images. The dependence of the asymmetry on inclination suggests a thin dust layer with a scale height smaller than the stellar populations. For the Hα and Hβ images, neither A

a
nor A

b
shows a significant correlation with inclination. Also, we do not find any significant dependence of the asymmetry of E(B − V)
g
on inclination, implying that the dust in the thick disk component is not significant. Compared to the SKIRT simulation, the results suggest that the thin dust disk has an optical depth of τ

V
∼ 0.2. This is the first time that the asymmetries caused by the dust attenuation and the inclination are probed statistically with a large sample. Our results indicate that the combination of the dust attenuation and the inclination effects is a potential indicator of the 3D disk orientation.
Narrowing the Mass Range of Fuzzy Dark Matter with Ultrafaint Dwarfs
Authors: Hayashi Kohei , Ferreira Elisa G. M. , Chan Hei Yin Jowett
Published: April 2021

Fuzzy dark matter (FDM) is an attractive dark matter candidate motivated by small-scale problems in astrophysics and with a rich phenomenology on those scales. We scrutinize the FDM model, more specifically the mass of the FDM particle, through a dynamical analysis for the Galactic ultrafaint dwarf (UFD) galaxies. We use a sample of 18 UFDs to place the strongest constraints to date on the mass of the FDM particle, updating on previous bounds using a subset of the sample used here. We find that most of the sample UFDs prefer an FDM particle mass heavier than 10−21 eV. In particular, Segue 1 provides the strongest constraint, with

. The constraints found here are the first that are compatible with various other independent cosmological and astrophysical bounds found in the literature, in particular with the latest bounds using the Lyα forest. We also find that the constraints obtained in this work are not compatible with the bounds from luminous dwarf galaxies, as already pointed out in the previous work using UFDs. This could indicate that although a viable dark matter model, it might be challenging for the FDM model to solve the small-scale problems.

The radio spectra of main-sequence stars remain largely unconstrained due to the lack of observational data to inform stellar atmosphere models. As such, the dominant emission mechanisms at long wavelengths, how they vary with spectral type, and how much they contribute to the expected brightness at a given radio wavelength are still relatively unknown for most spectral types. We present radio continuum observations of Altair, a rapidly rotating A-type star. We observed Altair with NOEMA in 2018 and 2019 at 1.34, 2.09, and 3.22 mm and with the Very Large Array in 2019 at 6.7 and 9.1 mm. In the radio spectra, we see a brightness temperature minimum at millimeter wavelengths followed by a steep rise to temperatures larger than the optical photosphere, behavior that is unexpected for A-type stars. We use these data to produce the first submillimeter to centimeter spectrum of a rapidly rotating A-type star informed by observations. We generated both PHOENIX and KINICH-PAKAL model atmospheres and determine the KINICH-PAKAL model better reproduces Altair’s radio spectrum. The synthetic spectrum shows a millimeter brightness temperature minimum followed by significant emission over that of the photosphere at centimeter wavelengths. Together, these data and models show how the radio spectrum of an A-type star can reveal the presence of a chromosphere, likely induced by rapid rotation, and that a Rayleigh Jean’s extrapolation of the stellar photosphere is not an adequate representation of a star’s radio spectrum.

Authors: Kalra Anirudh , Swami Vinit , Bhosale Veera
Published: April 2021

Aim: To study the skeletal, dental effects and evaluate the soft tissue changes with PowerScope-fixed functional appliance in class II malocclusion.

Materials and methods: This clinical study was carried out where a total of 10 growing (CVMS 3 and 4) Class II Division 1 malocclusion patients, indicated for treatment with fixed functional appliance were allocated based on specific inclusion criteria. PowerScope (American Orthodontics) was used as the fixed functional appliance. Skeletal, dental and soft tissue effects of the appliance with various angular and linear parameters on a digital lateral cephalogram were evaluated for all 10 participants. Records were collected before the insertion of PowerScope appliance (T0) and after 5 months, during the appliance removal (T1). All participants were treated with 0.018ʺ×0.025ʺ MBT (3M Unitek) prescription. Statistical analysis was performed using a paired t-test to compare individual mean changes for each treatment category. 

Results: Statistically significant changes were seen in skeletal parameters such as forward positioning of the mandible with an increase in SNB angle and N perpendicular-Pogonion distance, the class II jaw base relationship improved with reduction in ANB angle and Wits appraisal. Significant changes were observed in dental parameters such as forward positioning of mandibular incisors, maxillary molar distalization and intrusion with reduction in overbite and overjet respectively. In the soft tissue, a significant improvement in facial profile was seen due to an increase in labiomental angle.

Conclusions: The results of this study have shown that statistically significant changes in skeletal, dental and soft tissue parameters
Age and sex do not affect first year recurrence in patients with non-muscle invasive bladder cancer
Authors: Kocan Huseyin , Kadihasanoglu Mustafa
Published: April 2021

Introduction: Although demographic heterogeneity in the management of patients with non-muscle invasive bladder tumor (NMIBT) is an important factor, there are only minimal evidence-based recommendations that adjust for patient age and gender. The relationship and impact of age and gender on the recurrence in NBIMT is poorly investigated and understood.

Aim: The aim of the study was to evaluate the impact of age and sex on the recurrence of non-muscle invasive bladder cancer.

Materials and methods: Patients treated with transurethral resection (TUR) of primary NMIBT were included in the study. Risk calculation was made according to the European Organization for Research and Treatment of Cancer (EORTC) risk tables. Prognostic factors for predicting tumor recurrence up to 5 years including age and sex were analyzed. The Mann-Whitney U test was used for comparison of non-parametric variables in independent groups. Kaplan-Meier method, with log rank (Mantel-Cox) analyses applied for comparison of mean duration of remission by sex and age, was used to calculate mean duration of remission. 

Results: A total of 81 patients, 68 males (mean age 59.03 years) and 13 females (mean age 58.13 years) were eligible for final analysis. Mean survival time of patients <60 years old and older was 17.3±2.1 months (13.2–21.3) and 17.9±2.8 months (12.4–23.4), respectively (p=0.6). Mean survival time was 17.3±2.1 months for females and 15.4±2.1 months for males (p=0.08). However, 1-year tumor-free rate of female patients (53.8%) was not much different from that of males (31%) (p=0.11). Although considerable difference was observed between recurrence rates of patients according to sex, it failed to reach statistical significance.

Conclusions: The results of the present study suggest that the recurrence of NMIBT is not associated with age or gender. 
The genus Ismarus Haliday (Hymenoptera, Ismaridae) from China
Authors: Zhang Xiao , Chen Hua-yan , Liu Jing-xian , Luo Shi-xiao
Published: April 2021

The genus Ismarus Haliday from China is revised. Six species are recognized, of which two species are described as new: Ismarus areolatus Chen, sp. nov., and Ismarus paradorsiger Chen, sp. nov. By examining the pits along the anterolateral margin of mesoscutum and comparing them with the typical notauli in Diapriidae, we conclude that the so-called reduced notauli in Ismarus are actually foveae of the mesoscutual suprahumeral sulcus. An updated key to the Chinese species of the genus is provided.

Published: April 2021

Six new Brazilian species of the gall-associated Doryctinae genus Allorhogas are described and illustrated: A. copaibasp. nov., A. ilexaffinissp. nov., A. inquilinussp. nov., A. quarentenussp. nov., A. vassunungasp. nov. and A. viridissp. nov. We provide host plant records for five of these species, three and one of which are new host plant genera (Ilex L., Copaifera L. and Eugenia P. Micheli ex L.) and new host plant family (Aquifoliaceae) records, respectively. Allorhogas inquilinussp. nov., whose biology was previously reported, represents the first confirmed case of phytophagous inquilinism in the genus. An updated key to Brazilian species of Allorhogas is provided.
Formica species (Hymenoptera, Formicidae, Formicinae) in late Eocene Rovno amber
Authors: Radchenko Alexander G. , Perkovsky Evgeny E. , Vasilenko Dmitry V.
Published: April 2021

A new species, Formica ribbeckei Radchenko & Perkovsky, sp. nov., is described based on four workers from late Eocene Rovno amber (Ukraine). It most resembles F. flori Mayr, 1868 but differs from the latter mainly by the 5-segmented maxillary palps with the preapical segment subequal in length to the apical one, and by the shorter first funicular segment. Fossil F. luteola Presl, 1822, F. trigona Presl, 1822, F. macrognatha Presl, 1822 and F. quadrata Holl, 1829 are considered incertae sedis in Formicidae. Thus, ten valid Formica Linnaeus, 1758 species (including F. ribbeckei) are known now from late Eocene European ambers. The diversity of Formica in the early and middle Eocene deposits of Eurasia and North America is considered. It is assumed that the genus Formica most likely arose in the early Eocene.

Loin d’être absente de l’œuvre de Warburg, la notion d’ornement brille par son éclatement et son caractère composite. Cet article se propose de restituer et d’étudier la pluralité des conceptions warburgiennes de l’ornement à partir d’un motif particulier, le drapé.
L’engagement dans une pratique thérapeutique de méditation : le rôle clé de la spiritualité comme facteur d’observance
Authors: Weiss Amélie , Berghmans Claude
Published: April 2021

En France, depuis quelques décennies, la méditation est apparue comme un véritable phénomène. Devenue légitime par la science et enseignée par des médecins ou des coachs en développement, ces techniques d’Orient dont la plus populaire est la méditation de pleine conscience (MPC) sont aujourd’hui mieux connues. Développée dans le cadre de l’accompagnement de vécu psycho-affectif comme les rechutes dépressives ou encore le stress, cette pratique tend au développement de qualités de l’esprit telles que le non jugement, l’attention vigilante sur l’instant présent, la gestion des émotions. Cependant, en développant des programmes inspirés de la pleine conscience et en dénaturant l’objet de son cadre traditionnel, spirituel et religieux d’origine, n’a-t-on pas perdu le sens de cette pratique et n’est-ce pas un frein pour un engagement à long terme ? La question que nous nous posons est donc la suivante : une dynamique spirituelle dans laquelle le patient s’engagerait ne favoriserait-elle pas une immersion et une motivation à long terme à pratiquer des formes de méditation ? De plus, la perte de la compréhension du terme « méditation » dans un champ culturel, spirituel et religieux différent du cadre originel, ne créerait-elle pas un frein supplémentaire dans l’appréhension d’une pratique méditative ? Ces questionnements et leurs développements, abordés tout au long de cet article, semblent aller dans le sens de certains auteurs qui tendent à considérer une seconde vague d’interventions basées sur la pleine conscience. Nous questionnons ainsi ce nécessaire rendu de la dimension spirituelle à la méditation afin de permettre l’engagement actif qu’exige cet entraînement mental et ainsi, permettre un engagement sur le long terme pour en tirer les bénéfices de soulagement face à la souffrance.
Auriculothérapie et pathologies bucco-dentaires : l’occlusion dentaire
Authors: Vulliez Chantal
Published: April 2021

Introduction : L’auriculothérapie personnalisée appliquée à l’art dentaire permet de mieux expertiser et traiter les troubles occlusaux. Matériel et méthode : L’auricule est reliée à la sphère buccale par le système des nerfs crâniens et plus particulièrement le nerf trijumeau qui est responsable de l’innervation de tous les organes dentaires. L’auriculothérapie dentaire va nous permettre de repérer rapidement la ou les dents causales du trouble occlusal. Le signal NOGIER du RAC (ou VAS) est indispensable à cette localisation. Résultat : L’utilisation du laser Infrarouge fréquentiel (type PREMIO 32 D®) sur les points détectés au RAC, est un apport thérapeutique essentiel. Conclusion : L’auriculothérapie est une technique médicale essentielle pour la mise en place d’une occlusion physiologique.

Pourquoi Robert Walser a-t-il arrêté d’écrire après son internement à l’asile de Herisau ? L’auteur cherche des indices dans l’œuvre pour comprendre cet effacement, qui se déroule en plusieurs étapes. L’hypothèse est que l’écriture, toujours en excès, mêlant le frivole et le tragique, le futile et le sérieux, correspond à un état d’excitation qui met en danger la santé mentale du poète. Les angoisses pourraient être liées à des traumatismes précoces, non identifiables, que l’auteur qualifie de fantomatiques, dont on voit les traces dans la Correspondance, sous la forme des demandes infantiles adressées à M me  Mermet.
Écritures de soi, Écritures des limites
Authors: Schauder Silke
Published: April 2021

Le présent article propose une réflexion sur l’écriture de soi dans l’œuvre d’Ernest Hemingway et l’intrication entre œuvre, biographie et conflit psychique. Après avoir situé Le Vieil Homme et la Mer dans le contexte bio-bibliographique d’Ernest Hemingway, l’auteure propose une lecture de cette œuvre-clé. Elle met à l’épreuve l’hypothèse que la problématique de Hemingway et sa posture d’écrivain y sont déclinées sous forme d’allégorie. Puis, l’absence de publication majeure et son passage à l’acte suicidaire sont questionnés à la lumière d’un traumatisme infantile.

L’augmentation des accusations de plagiat depuis le xx e  siècle manifeste une distorsion pathologique des usages de la pensée au sein de la société et une souffrance insue de pensée chez le plagiaire (non pervers). Sont résumés les complexes processus du penser et des identifications dans l’apprendre à écrire dont celui majeur du copier, du mimer. Après un rappel d’écrits sur des plagiats, sont explorés les points de souffrance de cette faille identitaire sous l’angle des troubles de l’activité de pensée décrits par Bion.
