Probing the Icy Shell Structure of Ocean Worlds with Gravity–Topography Admittance
Authors: Akiba Ryunosuke , Ermakov Anton I. , Militzer Burkhard 
Published: March 2022

Abstract
The structure of the icy shells of ocean worlds is important for understanding the stability of their underlying oceans as it controls the rate at which heat can be transported outward and radiated to space. Future spacecraft exploration of the ocean worlds (e.g., by NASA’s Europa Clipper mission) will allow for higher-resolution measurements of gravity and shape than currently available. In this paper, we study the sensitivity of gravity–topography admittance to the structure of icy shells in preparation for future data analysis. An analytical viscous relaxation model is used to predict admittance spectra given different shell structures determined by the temperature-dependent viscosity of a tidally heated, conductive shell. We apply these methods to the ocean worlds of Europa and Enceladus. We find that admittance is sensitive to the mechanisms of topography support at different wavelengths and estimate the required gravity performance to resolve transitions between these mechanisms. We find that measuring admittance would be complementary to ice-penetrating radar in constraining shell thickness as it would cover the cases for which a direct ice–ocean interface detection is less favorable with radar, i.e., for warmer and thicker shells. Finally, we find that admittance may be used to constrain the tidal dissipation within the icy shell, which would be complementary to a more demanding measurement of the tidal phase lag.

BACKGROUND: The COVID-19 pandemic has changed the order of life in various aspects of life, including the field of education in Indonesia.
AIM: The purpose of the study was to determine student perceptions and acceptance of the online learning process during the COVID-19 pandemic.
METHODS: The research is in the form of a survey using Google Forms about the perception and acceptance of online lectures during the COVID-19 pandemic for nursing students at universities in Indonesia, a questionnaire sent via Whatsapp. Held from July 1, 2021, to July 30, 2021.
RESULTS: The many of respondents aged 17-19 years (50%) with a Diploma-students (62.9%). Most of them have intermediate-level skills in using information technology (82.2%). The platform that is often used is Zoom meeting. While other platforms are Whatsapp and Edmodo. The advantages of online learning are that students state that they can study from home (22.2%) and easily access online sources of material (19.9%) and can obtain recordings of each lesson (18.6%). Constraints that are often faced are technical problems (24.6%), very minimal interaction with lecturers (18.4%) and very minimal interaction between students (17.5%). Age and skills in using technology, information, and communication have a significant effect on students' perceptions of online learning (p<0.05). Most respondents have a negative perception (52.2%) about online learning.
CONCLUSION: Although there are several advantages to online learning, students' perceptions of the learning process are negative, meaning that they are happier and still want face-to-face learning.

Authors: Juteau Solène 
Published: March 2022

À la création d’une activité organisationnelle adossée aux technologies numériques, la transposition de la logique de l’organisation préexistante pourrait être une évidence. Cette recherche se propose d’en analyser la situation au sein d’un service de retrait de commandes de type Drive dans la Grande Distribution à partir de son lancement. Nous recherchons comment se déploie un jeu de logiques institutionnelles à l’adoption d’une innovation organisationnelle dans une organisation préexistante ? Pour y répondre, nous avons mené une étude interprétative fondée sur un cas unique. Nous avons élaboré une collecte de données combinant données primaires avec des entretiens semi-directifs et données secondaires avec des observations et des analyses documentaires. Les résultats de l’étude nous permettent de caractériser un modèle processuel en trois phases, précisant les conditions d’émergence de nouvelles modalités organisationnelles et institutionnelles.

Published: March 2022

Z raziskavo vodnoekoloških razmer na območju doline Zaloka leta 2020 smo sledili predhodni terenski študiji iz leta 1978. Zajeto je bilo isto območje, ki je bilo prvotno preučeno kot potencialno območje zajema pitne vode, danes pa je vključeno v komunalno oskrbo s pitno vodo za več kot 30.000 ljudi. Na podlagi fizikalno-kemijskih kazalnikov posameznih vodnih virov in podnebno-geoloških značilnosti območja smo ohranjanje dobrega vodnoekološkega stanja preučenih vodnih virov povezali s padavinskimi in hidrogeografskimi razmerami širšega območja izvira Ljubija. Nizka vsebnost nitratov in majhna nihanja tudi ostalih parametrov kažejo na majhen vpliv človeka.
The year 2020 water-ecological research followed the preliminary field study from 1978. We covered the same area of the Zaloka Valley, which was originally explored as a potential drinking water area, but today is included in municipal drinking water supply for more than 30,000 people. Based on physical-chemical indicators of individual water sources and climate-geological characteristics of the area, we associated the maintenance of good water-ecological status of the studied water sources with precipitation and hydrogeographic features of the wider area of the Ljubija karst spring. The low nitrate content and small fluctuations in other parameters describe the study area as an area with low human impact.
The necessity and appropriate range of the diagnostic “gray zone” of 13C-urea breath test
Authors: Yin Zhihao , Xiao Shiyu , Tian Xueli , Yuan Ziying , Zhou Liya 
Published: March 2022

Background:
The 13C-urea breath test (13C-UBT) is preferred for non-invasive detection of Helicobacter pylori (H. pylori); however, its accuracy drops when results fall between 2‰ and 6‰ (called the gray zone). This study aimed to evaluate the accuracy of 13C-UBT (cut-off point 4‰) between 2‰ and 6‰, find a more appropriate gray zone, and identify the factors influencing 13C-UBT.

Methods:
Patients with 13C-UBT results 2‰–6‰, over an eight-year period, were studied. H. pylori infection was diagnosed if patients were positive for either Warthin–Starry staining or quantitative real-time polymerase chain reaction (real-time PCR), and excluded if both were negative. Accuracy of 13C-UBT under different cut-off points was calculated, and the factors affecting 13C-UBT were analyzed.

Results:
A total of 208 patients were included, of whom 129 were H. pylori–positive. Sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of 13C-UBT were 71.32%, 83.54%, 64.08%, and 87.62%, respectively. When the cut-off point was changed to 2.15‰, the NPV of 13C-UBT reached a maximum (76.47%); when the cut-off point was changed to 4.95‰, PPV reached its maximum (93.22%). Therefore, the original gray zone (2‰–6‰) was adjusted to 2‰–4.95‰. Gastric antral intestinal metaplasia (OR = 3.055, 95% CI: 1.003–9.309) was an independent risk factor for false-negative 13C-UBT.

Conclusions:
Accuracy of 13C-UBT over 2‰–6‰ was poor, and the gray zone was changed to 2‰–4.95‰. 13C-UBT results over 2‰–4.95‰ should be interpreted with caution during mass screening of H. pylori, especially for patients with gastric antral intestinal metaplasia.

Authors: Alhammad Abdulaziz Saad , Mulafikh Dhaifallah S. , Alsaleh Saad A. 
Published: March 2022

Context:
The novel coronavirus disease (COVID-19) has swept globally, leading to a crisis that affects all aspects of human life.

Aims:
This study aimed to investigate the impact of COVID-19 on otolaryngology-head-and-neck surgery (ORL-HNS) residency training in Saudi Arabia and assess the study habits of residents during the pandemic and the impact of COVID-19 on training.

Settings and Design:
This was a cross-sectional quantitative study that utilized a 36-item questionnaire, investigating demographic data, study habits during the pandemic, clinical involvement in various training domains before and during the pandemic, and COVID-19-related exposure and training.

Subjects and Methods:
The questionnaire was sent to all ORL-HNS residents in Saudi Arabia via email, except those in their first year of residency.

Statistical Analysis Used:
A Wilcoxon signed-rank test was performed to assess the difference in clinical involvement before and during the pandemic.

Results:
A total of 165 residents participated in this study (response rate = 72.7%). A statistically significant decrease in clinical involvement from before to during the pandemic was noted in all training domains, including the average number of emergency consultations during on-call duty, outpatient clinics, in-office diagnostic procedures, and operative procedures for oto-neurotology, rhinology and skull base, head and neck, pediatric and airway, and facial plastic. However, an increase in the consultation via telemedicine was apparent during the pandemic in comparison to before.

Conclusion:
The COVID-19 pandemic has affected ORL-HNS residency training considerably. We recommend implementing alternative didactic strategies to mitigate the decreased exposure of residents to ORL-HNS clinical training.
Single Versus Multiple Mini-tract Percutaneous Nephrolithotomy for Staghorn Renal Stone
Authors: Tsai I-Chen , Chen Zhi-Hao , Lee Kau-Han , Liu Chien-Liang , Huang Steven K. , Chiu Allen W. 
Published: March 2022

Purpose:
Percutaneous nephrolithotomy (PCNL) is the standard procedure used for large kidney stones, and multiple tracts of PCNL are applied to achieve better stone clearance. However, the creation of multiple tracts may have the potential risk of bleeding and higher complication rates compared with single-tract procedures. We reviewed our experience managing staghorn calculi with multiple tracts compared with a single tract.

Materials and Methods:
Records of 36 patients with staghorn calculi who underwent PCNL at our institution between January 2018 and April 2020 were reviewed retrospectively. Nineteen patients were managed by single-tract access (Group 1), and 17 patients underwent multiple-tract access (Group 2). Both groups were compared in terms of perioperative findings and postoperative outcomes.

Results:
The mean number of percutaneous accesses in the multiple-tract group was 2.88, with most patients requiring two tracts. The mean duration of fluoroscopy screening and operative time was longer in Group 2. Stone-free rates were 59% and 70.5% in Groups 1 and 2, respectively. The mean hospital stay was similar in both groups. Complications included blood transfusion, resulting from a hemoglobin drop of 2.15 ± 0.96 and 1.59 ± 0.69 g/dL in Groups 1 and 2, respectively. Mean pre- and post-operative creatinine concentrations were 1.212 and 1.211 mg/dL in Group 1 and 1.206 and 1.157 mg/dL in Group 2. Mean changes in creatinine values were not statistically significant between the groups. Clavien–Dindo Classification Grade II complications included urosepsis and blood transfusion, which occurred in five patients in Group 1 and three in Group 2. Pseudoaneurysm attributed to Grade III complications occurred in one patient in Group 1.

Conclusion:
Multiple-tract access during PCNL is a safe and efficient method to manipulate staghorn kidney stones. Mini PCNL with multiple-tract access is a successful alternative to deal with staghorn stones involving multiple calyces.

Published: March 2022

Purpose:
This study evaluated the effectiveness and safety of transperitoneal laparoscopic ureterolithotomy (TPLU) and retroperitoneal laparoscopic ureterolithotomy (RPLU) in the surgical management of ureterolithiasis.

Materials and Methods:
The current prospective study was conducted at the Department of Urology, Dr. D. Y. Patil Medical College. The complete patient medical history including patient's age, sex, stone (size, number, and laterality), and past history of stone surgeries were evaluated. Based on the treatment method, the patients were divided into TPLU and RPLU group. Both the procedures were evaluated for parameters including operative technique, operating time, hospital stay, intra- and postoperative complications, conversion rate, success rate, and surgical ergonomics.

Results:
A total of 50 patients were included (TPLU, n = 25; and RPLU, n = 25). The average age was 43.6 years in the TPLU and 46.7 years in the RPLU group. The average size of calculi was >15 mm in both the groups. The operation time and blood loss were relatively higher in the TPLU group than RPLU group. The complete stone clearance was observed in both the groups. The pain in loin area and burning micturition were the most common complaints reported by the patients from both the groups. One patient from RPLU group was converted to open surgery. The calculi size in TPLU group was positively correlated with operative time (r = 0.535, P = 0.006), blood loss (r = 0.440, P = 0.028), and hospital stay (r = 0.430, P = 0.032).

Conclusion:
TPLU and RPLU are feasible techniques for the management of large ureteric stones that are not amenable to ureteroscopy or extracorporeal shockwave therapy.

This paper presents an account audition system based on (Expert System), an artificial intelligence technique. This paper presents an account audition system based on (Expert System), an artificial intelligence technique. Since the limited studies dealt with using artificial intelligence in a general and expert system in auditing accounts in Iraq (within the researcher's knowledge limits), the researcher tried to tackle these two subjects in his current study to apply them in reality. The expert system that is designed within rules and facts of knowledge base analyzes, audits, and extracts data from financial tables within accounting distributions consist included such as names of accounts and their numbers whose values are represented within cost centers represented by certain symbolic numbers that differ from one institution to another and obtaining the required results by using an applicable knowledge base. The Proposed system approach offers a practical method of auditing and distributing the required data by using the expert systems manually by many auditors.
Using the expert system led to lessening time and effort taken to make audits and the accuracy of obtaining results.
