Logistic regression model and Application using Functional Data Method
Authors:   The Korean Data Analysis Society, Lee Donghyuk , Kang KyungJun , Yang Hojin
Published: June 2022

Stock prices around the world dramatically decreased in 2020 due to COVID-19. Although the general trend seemed to be rebounding in 2021, the degree of recovery might vary by industry. This paper intends to investigate the relationship between the type of the industry companies and the pattern of individual stock indexes for 2021. Specifically, we investigate whether the functional pattern of individual stock indexes can be an important factor that can distinguish the type of the industry company. Traditionally, the stock price data has been analyzed using a time series approach. However, with the recent development of automated devices, the interest on the functional data analysis has been increasing. If individual stock prices are assumed to be random functions defined above continuous time, functional data techniques can be applied. Following this approach, we propose to use a functional logistic regression model that can explain the type of the industry company with the pattern of individual stock prices especially for 2021.
Equipment Reliability Process in Krško NPP
Authors: Gluhak Mario
Published: June 2022

To ensure long-term safe and reliable plant operation, equipment operability and availability must also be ensured by setting a group of processes to be established within the nuclear power plant. Equipment reliability process represents the integration and coordination of important equipment reliability activities into one process, which enables equipment performance and condition monitoring, preventive maintenance activities development, implementation and optimization, continuous improvement of the processes and long term planning. The initiative for introducing systematic approach for equipment reliability assuring came from US nuclear industry guided by INPO (Institute of Nuclear Power Operations) and by participation of several US nuclear utilities. As a result of the initiative, first edition of INPO document AP-913, ‘Equipment Reliability Process Description’ was issued and it became a basic document for implementation of equipment reliability process for the whole nuclear industry. The scope of equipment reliability process in Krško NPP consists of following programs: equipment criticality classification, preventive maintenance program, corrective action program, system health reports and long-term investment plan. By implementation, supervision and continuous improvement of those programs, guided by more than thirty years of operating experience, Krško NPP will continue to be on a track of safe and reliable operation until the end of prolonged life time.
NPP Krško Station Blackout Analysis after Safety Upgrade Using MELCOR Code
Authors: Šadek Siniša , Grgić Davor , Benčik Vesna
Published: June 2022

The analysis of a Station blackout (SBO) accident in the NPP Krško including thermalhydraulic behaviour of the primary system and the containment, as well as the simulation of the core degradation process, release of molten materials and production of hydrogen and other incondensable gases will be presented in the paper. The calculation model includes the latest plant safety upgrade with addition of Passive Autocatalytic Recombiners (PAR) and the Passive Containment Filter Venting (PCFV) system. The code used is MELCOR, version 1.8.6. MELCOR is an integral severe accident code which means that it can simulate both the primary reactor system, including the core, and the containment. The code is being developed at Sandia National Laboratories for the U.S. Nuclear Regulatory Commission. The analysis is conducted in two steps. First, the steady state calculation is performed in order to confirm the applicability of the plant model and to obtain correct initial conditions for the accident analysis. The second step is the calculation of the SBO accident with the leakage of the coolant through the damaged reactor coolant pump seals. Without any active safety systems, the reactor pressure vessel will fail after few hours. The mass and energy releases from the primary system cause the containment pressurization and rise of the temperature. The newly added safety systems, PAR and PCFV, prevent the damage of the containment building by keeping the thermalhydraulic conditions below the design limits. The analysis results confirm the capability of the safety systems to effectively control the containment conditions. Results of the analysis are given with respect to the results of the MAAP 4.0.7 analysis for the same accident scenario. The MAAP and MELCOR codes are the most popular severe accident codes and, therefore, it is reasonable to compare their results. In addition, sensitivity calculations performed by varying most influential parameters, such as the hot leg creep failure, blockage of a pipe connecting the cavity and the sump, inclusion of a radionuclide package in the MELCOR, etc. are done in order to demonstrate correct physical behaviour and the accuracy of the developed NPP Krško MELCOR model.
Verification of GOTHIC Multivolume Containment Model during NPP Krško DBA LOCA
Authors: Fancev Tomislav , Grgić Davor , Šadek Siniša
Published: June 2022

New containment multivolume model of NPP Krsko for GOTHIC code is developed. It is based on plant drawings and other available data. It is supported by developed SketchUp 3D containment model. The model is subdivided in volumes following physical boundaries and clearly defined flow paths. All important concrete heat structures are taken into account. Metal heat structures are based on plant’s SAR Chapter 6 licensing model. RCFC (Reactor Containment Fan Cooler) units are explicitly modelled as well as all main ventilation ducts. The model includes two trains of containment spray system. PARs (Passive Autocatalytic Recombiner) and PCFV (Passive Containment Filter Venting) filters added during plant safety upgrade project are part of the model too. It was intention to use model for both DBA (Design Basis Accident) and for DEC (Design Extended Conditions) and BDBA (Beyond Design Basis Accident) calculations. Based on the same discretization and data, and on experience acquired during GOTHIC model development and use, containment models for MELCOR and MAAP integral codes are developed too. As part of initial verification of the GOTHIC model containment DBA LOCA calculation is performed using SAR MER (Mass and Energy Release) data. The influence of different break positions on peak containment atmosphere pressure and temperature was studied. The results were compared against results obtained in single volume containment licensing model. Beside local effects due to different containment subdivision similar results are obtained when comparing containment dome from multivolume and the single volume in licensing model. Special attention was paid to distribution of water in lower part of the containment during recirculation phase. In this case much more valuable information are obtained in multivolume model with explicit volumes for main sump, recirculation sump and sump pit. Another point of interest was influence of containment spray duration on long term pressure and temperature behaviour. The intention was to study consistency of assumed different spray operation times used in safety analyses, EQ analyses and SAMGs and related consequences for plant operation during DBA LOCA.

A grain drier with a convection system that simultaneously acts as storage is known as an instore dryer. The purpose of this study was to see how drying and storage—In-Store Dryer— affected the physical and chemical qualities of maize. Drying takes place at an average drying temperature of 40-43°C, with an average RH of 76.8% in the environment and 52.2% in the dryer chamber. The maize can be dried for 4 – 5 days using pre-drying material with an initial moisture level of 30.14 percent to 10.56 percent, which is the right water content for storage. The nutritional components of maize after drying and storing for 4-5 days using the In-Store Dryer can be analyzed to maintain maize quality. At the same time, when temperatures rise, the water content of the crop decreases due to the convective process, reducing the crop's weight.

The performance of internal combustion engines should be improved depending on some technological requirements and rapid increase in the fuel expenses. On the other hand, the improvements in engine materials are forced by using alternative fuels and environmental requirements. Therefore, the performances of engine materials become increasingly important. For improving the performance of engine, thermal barrier coatings (TBCs) are a promising step forward. In this experimental study, alumina – (40 %) titania and nickel - chromium are used as the thermal barrier materials. The purpose of using these materials is to reduce the heat loss from engine. TBCs are done by atmospheric plasma spraying technique. Engine working conditions are maintained constant before and after coating. The results showed a reduction in specific fuel consumption. CO and HC emissions are slightly more than the conventional coated diesel engine at low and medium loads but lesser at higher loads whereas NOx is reduced.

Published: June 2022

Skin cancer is one of the most common cancers, and its early detection can have a huge impact on its outcomes. Deep learning, especially convolutional neural networks, perform well in processing massive amounts of data, especially image data in classifying skin cancer. In this paper, convolutional neural networks are mainly used to diagnose and classify 7 types of skin lesions, including melanoma, basal cell carcinoma, melanocytic nevus, actinic keratosis, and intraepithelial carcinoma, benign keratinoid lesions, dermatofibroma, and vascular lesions. First, the characteristics of skin lesion images are analyzed, using image processing technology and sampling technology to preprocess skin lesion images. Then the training parameters of imageNet network are adjusted through the idea of transfer learning on InceptionV3, ResNet50, DenseNet201, and other networks to perform training classification. Furthermore, different convolutional neural network models are built for classification. In order to validate the classification performance of various convolutional neural network models, this paper adopts ISIC 2017 HAM10000 dataset for experiments. The experimental results show that proper preprocessing is necessary when applying CNN for image classification. In classifying the 224*224 skin lesion images, the classical deep convolutional network with DenseNet201 achieved a remarkable performance classification accuracy of 99.12% for training and 86.91% for testing.

Here, we aimed to identify important plant areas (IPAs) in the Fergana Valley, one of the most densely human-populated regions in Central Asia with a diverse array of endemic and endangered species. The IPA programme in FV aims to identify and protect a global network of plant conservation sites. We conducted a field survey from 2018 to 2021 to re-identify specimens collected from Fergana Valley and stored at the National Herbarium of Uzbekistan (TASH). An analysis of the floristic, geobotanical and collected data allowed for the identification of the badlands in the northern foothills (Chap tract and surrounding areas) as an IPA site. We modified the interpretation of criterion A for IPAs to suit the circumstances of Mountainous Central Asia and documented the distribution of 29 species in the IPAs under these sub-criteria. To our knowledge, this is the first study to identify an IPA in Uzbekistan and provide geographic coordinates with locations for the herbarium specimens used to create the IPA set for Central Asia. Our study provides a foundation for applying future IPAs in this region, addressing specific conservation challenges, such as conserving rare and endangered species that grow outside protected areas and GIS mapping of endemic species.

Published: June 2022

Régulièrement, des acteurs s’étonnent que les dépenses de formation ne soient pas reconnues comme des dépenses d’investissement et, donc, ne puissent pas être inscrites à l’actif du bilan de l’entreprise puis amorties. L’article montre que les normalisateurs comptables ont de bonnes raisons de ne pas s’ouvrir trop à l’activation des dépenses de formation sans pour autant vouloir leur dénier leur caractère d’investissement. Dans le prolongement, l’auteur propose aux acteurs d’emprunter un autre cheminement pour activer l’investissement formation qui présuppose d’arriver à repenser les situations de formation pour pouvoir les penser également comme des situations de gestion.
Un cheminement vers la didactique de la conception
Authors: Didier John
Published: June 2022

Depuis Lebahar, l’appellation didactique de la conception continue d’être utilisée par plusieurs auteurs. Cette appellation participe au déploiement des travaux menés par les didactiques professionnelle et disciplinaires. La didactique de la conception, tel un territoire scientifique toujours en activité, propose de nouveaux horizons théoriques et de nouveaux dialogues pour la formation. Dans cette perspective, l’auteur investigue les filiations entre l’activité de conception, l’enseignement du design et la technologie. La formation à la conception mobilise un appareillage conceptuel issu des didactiques qu’il convient de préciser et de questionner. Pour comprendre l’activité de conception aux prises avec les différents contextes de formation, l’article adopte plusieurs entrées théoriques : didactique, ergonomie, psychologie et sciences de l’ingénieur.

Published: June 2022

Dans le contexte de la crise sanitaire du début des années 2020, nous avons cherché à identifier les facteurs qui déterminent le positionnement du public français en faveur ou en défaveur de la vaccination. Au moyen d’une enquête diffusée sur internet, nous explorons ici plus particulièrement les liens qui existent entre la volonté de se faire vacciner ou non et les profils d’utilisateurs des médias. Nos résultats indiquent que les personnes qui sont en faveur de la vaccination ont des pratiques médiatiques très différentes des personnes qui sont en sa défaveur. En effet, il apparaît que les personnes qui ne souhaitent pas se faire vacciner ne font pas confiance aux médias traditionnels et s’informent généralement sur internet et souvent sur des sites d’information alternatifs. Ce faisant, ces personnes seraient davantage exposées aux fake news et risqueraient davantage de les croire, ce qui aurait tendance à conforter leur défiance vis-à-vis de la médecine conventionnelle et leur décision de ne pas se faire vacciner.
Zero-diffusion limit for aggregation equations over bounded domains
Authors: Fetecau Razvan C. , Huang Hui , Messenger Daniel , Sun Weiran
Published: June 2022

We investigate the zero-diffusion limit for both continuous and discrete aggregation-diffusion models over convex and bounded domains. Our approach relies on a coupling method connecting PDEs with their underlying SDEs. Compared with existing work, our result relaxes the regularity assumptions on the interaction and external potentials and improves the convergence rate (in terms of the diffusion coefficient). The particular rate we derive is shown to be consistent with numerical computations.
MRI image enhancement based on feature clustering in the NSCT domain
Authors: Chang Xia , Zhao Haixia , Xue Zhenxia
Published: June 2022

The noise and low clarity in magnetic resonance imaging (MRI) images impede the doctor's diagnosis. An MRI image enhancement method is proposed in the non-subsampled contourlet transform (NSCT) domain. The coefficients of the NSCT are classified as noise component, weak edges component and strong edges component by feature clustering. We modified the transform coefficients to enhance the MRI images. The coefficients corresponding to noise are set to zero, the coefficients corresponding to strong edges are essentially unchanged, and the coefficients corresponding to weak edges are enhanced by a simplified nonlinear gain function. It is shown that the proposed MRI image enhancement method has advantages in visual quality and objective evaluation indexes compared to the state-of-the-art methods.
The Analysis of Two-Way E-Commerce Credit Evaluation Model Based on the C2C Mode
Authors: Li Zhezhou , Dai Rui , Feng Xuan , Xiong Yueming
Published: June 2022

As an important mode of e-commerce, C2C has become a trading mechanism favored by consumers. However, for C2C transaction in a virtual environment, there is an issue of congenital transaction asymmetry, leading to increased uncertainties and transaction risks as well as credit speculation, false transactions and other credit problems. These problems not only affect the development of enterprises to a large extent, but also hinder the development of e-commerce ultimately. In order to guarantee the safety of both transaction parties, it is particularly important to establish a sound credit evaluation system for shopping sites. Through the analysis of the shortcomings of the existing C2C e-commerce credit evaluation model, this paper proposes a two-way e-commerce credit evaluation model based on the C2C mode. Firstly, a cross-platform two-way credit rating center with a unified rating standard was constructed; secondly, the credit evaluation indicator was reset and revised; then the credit rating of buyers and sellers was unified by combining fuzzy comprehensive evaluation algorithm and

Trigeminal nerve stimulation for disorders of consciousness
Authors: Dong Xiao-Yang , Tang Yun-Liang , Fang Long-Jun , Feng Zhen
Published: June 2022

According to previous case reports, trigeminal nerve stimulation (TNS) can be successfully used to wake a non-responsive unconscious patient. However, no studies have comprehensively investigated the effect of TNS on patients with disorders of consciousness (DOC). Therefore, the present study aimed to assess the safety and efficacy of TNS in DOC patients recruited at the First Affiliated Hospital of Nanchang University. We used Coma Recovery Scale-Revised (CRS-R) scores to assess patients at baseline and after 1–4 weeks of TNS. The patients were further followed up for 4 weeks after the last stimulation to evaluate the safety of the procedure. The participant group comprised 21 DOC patients with an acquired brain injury who were more than 3 months post-injury. The participants were 44.29 ± 12.55 years old and 5.52 ± 1.83 months post-DOC onset, and included 12 patients who were in a vegetative state or had unresponsive wakefulness syndrome and 9 patients who were in a minimally conscious state. Compared with CRS-R scores at baseline, those at weeks 4 and 8 showed no significant improvements in any of the DOC patients. Nonetheless, CRS-R scores improved throughout the study period in 8 out of the 21 DOC patients. Among those with improved scores, two patients in a minimally conscious state had improved CRS-R scores at week 4, while five had improved scores at 4 weeks later. Only one patient with vegetative state/unresponsive wakefulness syndrome had recovered to a minimally conscious state at week 4. Importantly, no obvious treatment-related adverse events were considered to be related to TNS. Taken together, these data provide early evidence that TNS may be an effective and safe approach for promoting the recovery of consciousness in patients with neurological disorders.

To design a treatment plan for patients with epididymal obstruction, we explored the potential impact of factors such as body mass index (BMI) and age on the surgical outcomes of vasoepididymostomy (VE). In this retrospective study, 181 patients diagnosed with obstructive azoospermia (OA) due to epididymal obstruction between September 2014 and September 2017 were reviewed. All patients underwent single-armed microsurgical intussusception VEs with longitudinal two-suture placement performed by a single surgeon (KH) in a single hospital (Peking University Third Hospital, Beijing, China). Six factors that could possibly influence the patency rates were analyzed, including BMI, age, mode of anastomosis, site of anastomosis, and sperm motility and quantity in the intraoperative epididymal fluid. Single-factor outcome analysis was performed via Chi-square test and multivariable analysis was performed using logistic regression. A total of 159 (87.8%, 159/181) patients were followed up. The follow-up time (mean ± standard deviation [s.d.]) was 27.7 ± 9.3 months, ranging from 12 months to 48 months. The overall patency rate was 73.0% (116/159). The multivariable analysis revealed that BMI and age significantly influenced the patency rate (P = 0.008 and 0.028, respectively). Younger age (≤28 years; odds ratio [OR] = 3.531, 95% confidence interval [95% CI]: 1.397–8.924) and lower BMI score (<26.0 kg m−2; OR = 2.352, 95% CI: 1.095–5.054) appeared to be associated with a higher patency rate. BMI and age were independent factors affecting the outcomes of microsurgical VEs depending on surgical expertise and the use of advanced technology.

Published: June 2022

Introduction:

Skin is the largest organ in the human body and mirrors the changes in the organism it envelops. Internal malignancies can cause various specific and non-specific cutaneous manifestations along with hair, nail and oral mucosal changes. Some of the changes are detected early indicating a strong association with cancer, while some occur in later stage indicating dissemination or immunosuppression. The present study is an effort to know pattern of dermatosis associated with internal malignancies so that early diagnosis and interventions can be done.

Aim:

To determine the pattern of specific and non-specific dermatosis associated with internal malignancy.

Methods and Material:

Patients of internal malignancies with skin lesions attending dermatology and oncology department during July 2020 to June 2021 were recruited in the study after taking written informed consent. A detailed history of skin lesions and malignancies were taken. Clinical examination (skin/hair/nail) was carried out and photographs were taken. Relevant investigations were carried out. Frequency and percentage of dermographic data and dermatosis associated with internal malignancies were calculated.

Results:

The study included 150 patients with maximum number of patients 78 (52%) in 41-60 years of age group with female: male ratio of 1.2:1. Most common internal malignancy was breast carcinoma in 43 (28.67%) cases. Specific dermatosis were seen in 5 (3.33%) cases and non-specific dermatosis in 121 (80.66%) cases. Specific dermatosis were vasculitis, necrolytic migratory erythema, lymphocytoma cutis, growth and cutaneous metastasis with 1 (0.67%) patient each. Most common non-specific dermatosis was herpes zoster in 17 (11.33%) cases.

Conclusion:

The study was useful in understanding the various specific and non specific dermatosis associated with internal malignancies and thereby helping the physician to manage the conditions.

Published: June 2022

Background:

Renal cell carcinoma (RCC) presents with inferior vena cava (IVC) thrombus in 10%–30% cases and surgical management forms the mainstay of the treatment. The objective of this study is to assess the outcomes of the patients undergoing radical nephrectomy with IVC thrombectomy.

Methods:

A retrospective analysis of patients undergoing open radical nephrectomy with IVC thrombectomy between 2006 till 2018 was done.

Results:

A total of 56 patients were included. The mean (±standard deviation) age was 57.1 (±12.2) years. The number of patients with levels I, II, III, and IV thrombus were 4, 29,10, and 13, respectively. The mean blood loss was 1851.8 mL, and the mean operative time was 303.3 minutes. Overall, the complication rate was 51.7%, while the perioperative mortality rate was 8.9%. The mean duration of hospital stay was 10.6 ± 6.4 days. The majority of the patients had clear cell carcinoma (87.5%). There was a significant association between grade and stage of thrombus (P = 0.011). Using Kaplan–Meier survival analysis, the median overall survival (OS) was 75 (95% confidence interval [CI] = 43.5–106.5) months, and the median recurrence-free survival (RFS) was 48 (95% CI = 33.1–62.3) months. Age (P = 0.03), presence of systemic symptoms (P = 0.01), radiological size (P = 0.04), histopathological grade (P = 0.01), level of thrombus (P = 0.04), and invasion of thrombus into IVC wall (P = 0.01) were found to be significant predictors of OS.

Conclusion:

The management of RCC with IVC thrombus poses a major surgical challenge. Experience of a center along with high-volume and multidisciplinary facility particularly cardiothoracic facility provides better perioperative outcome. Though surgically challenging, it offers good overall-survival and recurrence-free survival.

Published: June 2022

Background:

Delirium in critically ill patients is independently associated with poor clinical outcomes. There is a scarcity of published data on the prevalence of delirium among critically ill patients in Saudi Arabia. Therefore, we sought to determine, in a multicenter fashion, the prevalence of delirium in critically ill patients in Saudi Arabia and explore associated risk factors.

Methods:

A cross-sectional point prevalence study was conducted on January 28, 2020, at 14 intensive care units (ICUs) across 3 universities and 11 other tertiary care hospitals in Saudi Arabia. Delirium was screened once using the Intensive Care Delirium Screening Checklist. We excluded patients who were unable to participate in a valid delirium assessment, patients admitted with traumatic brain injury, and patients with documented dementia in their medical charts.

Results:

Of the 407 screened ICU patients, 233 patients were enrolled and 45.9% were diagnosed with delirium. The prevalence was higher in mechanically ventilated patients compared to patients not mechanically ventilated (57.5% vs. 33.6%; P < 0.001). In a multivariate model, risk factors independently associated with delirium included age (adjusted odds ratio [AOR], 1.021; 95% confidence interval [CI], 1.01–1.04; P = 0.008), mechanical ventilation (AOR, 2.39; 95% CI, 1.34–4.28; P = 0.003), and higher severity of illness (AOR, 1.01; 95% CI, 1.001–1.021; P = 0.026).

Conclusion:

In our study, delirium remains a prevalent complication, with distinct risk factors. Further studies are necessary to investigate long-term outcomes of delirium in critically ill patients in Saudi Arabia.

Published: June 2022

Background:

Wide differences in the estimates of acute kidney injury (AKI) have been reported in studies from various parts of the world. Due to dearth of data from the region, we carried out the present study to assess the incidence and the associated factors for AKI in our critically ill population.

Methods:

A prospective, observational study in critically ill adults who developed AKI was carried out. The diagnosis of AKI was attained by AKI Network (AKIN) criteria. The key details collected included details related to demographics, APCAHE score, concomitant diagnoses, whether mechanical ventilation was provided or not, radiological findings, drugs with potential nephrotoxicity, requirement of renal replacement therapy (RRT), whether recovered from AKI and time taken for recovery, duration of stay in the intensive care unit, and outcome (died/alive).

Results:

One hundred patients out of the total 560 with an incidence of 17.9% developed AKI. Forty-five had Stage 1, 22 had Stage 2, and 33 had Stage 3 AKI, and a significantly higher mortality was observed with Stage 3 AKIN Class compared to Stages 1 and 2. Two-thirds of the patients had septic shock, while 29 had contrast-induced nephropathy. Ninety-five patients received at least one drug with potential nephrotoxicity. Sixty-three patients recovered from AKI episodes. Only 29 patients underwent RRT of which 41% died.

Conclusion:

We observed an incidence of 17.9% for AKI in our critically ill patients. The estimates from this study will serve as a baseline for future studies in the region.
