Miscibility and Phase Separation in PMMA/SAN Blends Investigated by Nanoscale AFM-IR
Authors: Resch Julia , Dreier Julia , Bonten Christian , Kreutzbruck Marc
Published: November 2021

The miscibility and phase separation of poly(methyl methacrylate) (PMMA) and styrene-acrylonitrile (SAN) have already been investigated using various methods. However, these methods have limitations that often result in inconsistent characterization. Consequently, the reasons for the dependence of miscibility on composition as well as on processing temperature have not yet been proved. The phase separation of PMMA/SAN blends was therefore investigated for the first time using a novel technique, nanoscale AFM-IR. It couples nanoscale atomic force microscopy (AFM) with infrared (IR) spectroscopy. Therefore, the phase morphology can be chemically identified and precisely classified within the nm-regime. The PMMA/SAN blends, on the other hand, were analyzed of their changes in morphology under different thermal treatments. It was possible to visualize and define the phase separation, as well as dependence of the miscibility on the mixing ratio. In the miscible domain, no two individual phases could be detected down to the nanometer range. It was shown that with increasing temperature, the morphology changes and two different phases are formed, where the phase boundaries can be sharply defined. The onset of these changes could be identified at temperatures of about 100 °C.

Authors: Lin Bowen , Li Chengqiang , Chen Fangping , Liu Changsheng
Published: November 2021

Starch/PBAT blown films with high ultraviolet aging resistance and excellent mechanical properties were prepared by introducing lignin with polyurethane prepolymer (PUP) as a starch modifier and physical compatibilizer and 4,4′–methylene diphenyl diisocyanate (MDI) as a crosslinker. Starch was modified by reacting the NCO groups of the PUP with the OH groups of the starch to form a carbamate bond. The mechanical properties, hydrophobic properties, ultraviolet barrier, ultraviolet aging properties and microscopic morphology of starch/PBAT films with different contents of lignin were investigated. The results showed that the starch/PBAT films were blown continuously. The addition of lignin did not decrease the mechanical properties. On the contrary, the film with 1% lignin possessed the excellent mechanical properties with longitudinal tensile strength of 15.87 MPa and the elongation at a break of 602.21%. In addition, the higher the lignin content, the better the UV blocking effect. The introduction of lignin did not affect the crystalline properties but improved the hydrophilic properties and sealing strength of the high starch content composite films.
Exploring the Effects of MXene on Nonisothermal Crystallization and Melting Behavior of β-Nucleated Isotactic Polypropylene
Authors: Peng Wanxin , Sun Furui , Liang Yuke , Kang Jian , Chen Jinyao , Wang Wei , Cao Ya , Xiang Ming
Published: November 2021

In this study, one of the commonly used MXene (Ti3C2Tx) and β nucleated isotactic polypropylene (β-iPP)/MXene composites of different compositions were fabricated. The effects of MXene on non-isothermal crystallization and polymorphic behavior of β-iPP/MXene composites were comparatively studied. The non-isothermal crystallization kinetics indicates that for all samples, the lower cooling rates promote composites to crystallize at higher temperatures. When MXene and β-Nucleating agent (β-NA) are added separately, the crystallization temperature of composites shifts towards higher temperatures at all cooling rates. When MXene and β-NA are added simultaneously, the composite shows different cooling rate dependence, and the effects of improving crystallization temperatures is more obvious under rapid cooling. The activation energy of four samples iPP, iPP/MXene, iPP/β-NA, and iPP/MXene/β-NA were −167.5, −185.5, −233.8, and −218.1 kJ/mol respectively, which agree with the variation tendency of crystallization temperatures. The polymorphic behavior analysis obtained from Differential Scanning calorimetry (DSC) is affected by two factors: the ability to form β-crystals and the thermal stability of β-crystals. Because β-crystals tend to recrystallize to α-crystals below a critical temperature, to eliminate the effect of β-α recrystallization, the melting curves at end temperatures Tend = 50 °C and Tend = 100 °C are comparatively studied. The results show that more thermally unstable β-crystals would participate in β-α recrystallization with higher cooling rates. Moreover, thermal stability of β-crystals is improved by adding MXene. To further verify these findings, samples of three different thermal conditions were synthesized and analyzed by DSC, X-Ray Diffraction (XRD), and Polarized Light Optical Microscopy (PLOM), and the results were consistent with the above findings. New understandings of synthesizing β-iPP/MXene composites with adjustable morphologies and polymorphic behavior were proposed.

Authors: Rochardjo Heru S. B. , Budiyantoro Cahyo
Published: November 2021

Currently, fiber-reinforced thermoplastic composites are widely applied in structural applications. It has great potential to replace metal structures and provides advantages in weight reduction. In this study, the pretensioned unidirectional carbon fiber was overmolded by Polyamide 6 contained 30%wt of glass fibers (PA 6-30GF). Process parameters such as injection pressure, melting temperature, duration of carbon fiber cryogenic treatment, and fiber pretension were optimized to maximize the flexural strength, impact strength, and interlaminar properties of the hybrid composite. The relationship between factors and responses was analyzed using Box–Behnken design (BBD) from response surface methodology (RSM) and analysis of variance (ANOVA). Three levels were assigned for each factor. There were 27 experimental trials carried out, and a significant regression for the coefficient between the factors was derived. The BBD and ANOVA analysis demonstrate that the predicted values from the model are in satisfactory correlation with the experimental results. The optimum responses found were achieved by setting the following injection molding parameters: melting temperature of 278 °C and injection pressure of 122 bar. Carbon fiber, as a unidirectional reinforcement, should be immersed in liquid nitrogen for 10 min and mounted on the mold in a pretensioned state with a force of 100 N. The combination of these parameters can produce an optimum flexural strength of 248.6 Mpa, impact strength of 173.4 kJ/m2 and an ILSS of 30.4 Mpa.
Equivalent Circuit Establishments of a GaN High-Electron-Mobility Transistor and 635 nm Laser Diode for a Short-Pulsed Rising Current Simulation
Authors: Pai Kai-Jun , Lin Chang-Hua
Published: November 2021

In this paper, a dynamic operational linear regulator (DOLR) based on a GaN high-electron-mobility transistor (HEMT) and wide-bandwidth operational amplifier was developed and implemented. The driving current could be regulated and controlled by the DOLR for 632 nm laser diodes. The constant-current mode for the continuous-wave laser and the pulse-width modulation (PWM) mode for the short-pulsed laser were realizable using this DOLR. This study focused on the rising-edge time change on the laser driving current when the DOLR was operated under the high-frequency PWM mode, because the parasitic components on the GaN HEMT, laser diodes, printed circuit board, and power wires could influence the current’s dynamic behavior. Therefore, the equivalent circuit models of the laser diode and GaN HEMT were applied to establish a DOLR simulation circuit in order to observe the rising-edge time change on the laser driving current. A DOLR prototype was achieved, and so experimental waveform measurements could be implemented to verify the DOLR simulation and operation.
The Metaphysics of Theism: A Classical and Neo-Classical Synthesis
Authors: Sijuwade Joshua Reginald
Published: November 2021

This article aims to provide a metaphysical elucidation of the notion of Theism and a coherent theological synthesis of two extensions of this notion: Classical Theism and Neo-Classical Theism. A model of this notion and its extensions is formulated within the ontological pluralism framework of Kris McDaniel and Jason Turner, and the (modified) modal realism framework of David Lewis, which enables it to be explicated clearly and consistently, and two often raised objections against the elements of this notion can be successfully answered.
Stochastic Claims Reserving Methods with State Space Representations: A Review
Authors: Chukhrova Nataliya , Johannssen Arne
Published: November 2021

Often, the claims reserves exceed the available equity of non-life insurance companies and a change in the claims reserves by a small percentage has a large impact on the annual accounts. Therefore, it is of vital importance for any non-life insurer to handle claims reserving appropriately. Although claims data are time series data, the majority of the proposed (stochastic) claims reserving methods is not based on time series models. Among the time series models, state space models combined with Kalman filter learning algorithms have proven to be very advantageous as they provide high flexibility in modeling and an accurate detection of the temporal dynamics of a system. Against this backdrop, this paper aims to provide a comprehensive review of stochastic claims reserving methods that have been developed and analyzed in the context of state space representations. For this purpose, relevant articles are collected and categorized, and the contents are explained in detail and subjected to a conceptual comparison.

Authors: Machado Miguel A. , Rosado Luís S. , Mendes Nuno M. , Miranda Rosa M. , Santos Telmo G.
Published: November 2021

Automobile laser brazing remains a complex process whose results are affected by several process variables that may result in nonacceptable welds. A multisensory customized inspection system is proposed, with two distinct non-destructive techniques: the potential drop method and eddy current testing. New probes were designed, simulated, produced, and experimentally validated in automobile’s laser-brazed weld beads with artificially introduced defects. The numerical simulations allowed the development of a new four-point probe configuration in a non-conventional orthogonal shape demonstrating a superior performance in both simulation and experimental validation. The dedicated inspection system allowed the detection of porosities, cracks, and lack of bonding defects, demonstrating the redundancy and complementarity these two techniques provide.

Authors: Ma Yu , Zhang Yangrui , Li Song , Sun Weimin , Lewis Elfed
Published: November 2021

The use of optical fiber probe in two-phase flow measurements is very frequently encountered, especially in the applications of chemical engineering and petroleum industries. In this work, the influence of bubble piercing signals caused by bubble deformation is studied experimentally using a laboratory-prepared wedge-shaped fiber probe in a lab-scale gas–liquid flow generator. A three-dimensional simulation model is established to study the influence of bubble deformation on the piercing signals. A theoretical analysis of the characteristics of the pre-signal influenced by the bubble deformations is undertaken for a wide range of different modeled bubble shapes. Combining the experimental and simulation results, a promising analytical method to estimate the bubble shapes by analyzing the characteristics of pre-signals is proposed. The results of this investigation demonstrate that it is possible to estimate the bubble shapes before the fiber probe contacts the bubble surface. The method developed in this investigation is therefore highly promising for reducing errors caused by deformation during the probe piercing process.

Published: November 2021

Recovery of therapeutic or functional ambulatory capacity in patients with rotator cuff injury is a primary goal of rehabilitation. Wearable powered exoskeletons allow patients to perform repetitive practice with large movements to maximize recovery, even immediately after the acute event. The aim of this paper is to describe the usability, acceptability and acceptance of a hybrid exoskeleton for upper-limb passive rehabilitation using the System Usability Scale (SUS) questionnaire. This equipment, called ExoFlex, is defined as a hybrid exoskeleton since it is made up of rigid and soft components. The exoskeleton mechanical description is presented along with its control system and the way motion is structured in rehabilitation sessions. Seven patients (six women and one man) have participated in the evaluation of this equipment, which are in the range of 50 to 79 years old. Preliminary evidence of the acceptance and usability by both patients and clinicians are very promising, obtaining an average score of 80.71 in the SUS test, as well as good results in a questionnaire that evaluates the clinicians’ perceived usability of ExoFlex.
LC-DEX: Lightweight and Efficient Compressed Authentication Based Elliptic Curve Cryptography in Multi-Hop 6LoWPAN Wireless Sensor Networks in HIP-Based Internet of Things
Authors: Bettoumi Balkis , Bouallegue Ridha
Published: November 2021

The high level of security requirements and low capabilities of constrained devices that are connected to the Internet of Things (IoT) constitute a new challenge in terms of proposing an authentication solution that deals with the problem of energy constraints. The Host Identity Protocol Diet EXchange (HIP DEX) is primarily designed to be suitable for constrained devices and designed to be resistant to Denial of Service (DoS) and man-in-the-middle (MITM) attacks. In this paper, we propose an efficient saving energy solution to secure end-to-end (E2E) communications based on the compression of the IPv6 over Low Power Wireless Personal Area Networks (6LoWPAN) header for HIP DEX packets. We implement our solution in an IoT based-WSN over Constrained Application Protocol (CoAP) in the application layer and Routing Protocol for Low power and lossy networks (RPL) in the routing layer. We also propose a novel distribution model that minimizes the number of signaling messages. Both proposed compression and distribution models for HIP DEX combined with an original implementation of an opportunistic association establishment of the handshake, constitute an efficient security solution for IoT. We called our solution Lightweight Compressed HIP DEX in the IoT (LC-DEX).

One of the goals of any oil terminal is to make a business while avoiding hazardous events and harmful effects for both humans and the environment. This can be achieved by creating a safe working place as well as by performing safe and acceptable activities regarding the impact on surrounding objects, including residential and industrial areas. The aim of the hazard analysis of the oil terminal is to assess the risks related to hazardous events or phenomena and to evaluate whether the assessed risks are acceptable. The hazard analysis and assessment of risk are also used for risk reduction while examining and limiting hazardous scenarios that, for instance, involve the loss-of-containment of flammable or combustible material. In this paper, the authors aim to contribute to risk research by providing a comprehensive methodology of risk assessment for oil terminals with case study results and discussion on features of the methodology, risk aggregation, its applicability for risk reduction, and industrial interests. The performed study considered the “Klaipedos Nafta AB” (an operator of the Klaipeda Oil Terminal, Lithuania) case study regarding hazardous materials that might be released from various tanks, devices, and associated pipelines. The performed quantitative risk assessment has enabled the determination of the probability regarding whether releases would ignite and, for instance, cause explosion. In the case study, the estimate of probability, i.e., the frequency, and the possible consequences of the hazardous events were evaluated, and both mitigation and risk reduction measures were also considered.
LEADER Program—An Inclusive or Selective Instrument for the Development of Rural Space in Romania?
Authors: Opria Ana-Maria , Roșu Lucian , Iațu Corneliu
Published: November 2021

The LEADER program is one of the European Union’s financing instruments dedicated to the development of the rural communities. The instrument was introduced in the Romanian rural territory in 2007, a territory characterised by a high level of local and regional economic inequalities. The main goal of the present research is to question whether the development level specific to the rural communities have influenced their performance in managing the LEADER program. In order to answer this question, the characteristics of the initial level of development were analysed in relation to the spatial distribution of LEADER funds. The indicators taken into consideration were the number of projects, funds per capita, funds per Local Action Group (LAG), and the percentage of employees from the total population. In order to assess the relation between the initial level of development and the LAG’s performance, the method used was the Ordinary Least Squares regression, which calculates a set of statistical parameters that highlight the presence, form, sense, and intensity of the dependency relation. The results highlight no correlation between the level of development and the spatial distribution of the LEADER funds. Analysing the data, the paper reveals that the LEADER program is an inclusive rather than a selective instrument for the development of Romanian rural communities, despite other examples researched in Western countries. The results show that the LEADER program can have an influence in reducing the rural disparities, but its effects are of low importance.
Symmetry in Emotional and Visual Similarity between Neutral and Negative Faces
Authors: Riberto Martina , Talmi Deborah , Pobric Gorana
Published: November 2021

Is Mr. Hyde more similar to his alter ego Dr. Jekyll, because of their physical identity, or to Jack the Ripper, because both evoke fear and loathing? The relative weight of emotional and visual dimensions in similarity judgements is still unclear. We expected an asymmetric effect of these dimensions on similarity perception, such that faces that express the same or similar feeling are judged as more similar than different emotional expressions of same person. We selected 10 male faces with different expressions. Each face posed one neutral expression and one emotional expression (five disgust, five fear). We paired these expressions, resulting in 190 pairs, varying either in emotional expressions, physical identity, or both. Twenty healthy participants rated the similarity of paired faces on a 7-point scale. We report a symmetric effect of emotional expression and identity on similarity judgements, suggesting that people may perceive Mr. Hyde to be just as similar to Dr. Jekyll (identity) as to Jack the Ripper (emotion). We also observed that emotional mismatch decreased perceived similarity, suggesting that emotions play a prominent role in similarity judgements. From an evolutionary perspective, poor discrimination between emotional stimuli might endanger the individual.
A Sparse Quasi-Newton Method Based on Automatic Differentiation for Solving Unconstrained Optimization Problems
Authors: Cao Huiping , An Xiaomin
Published: November 2021

In our paper, we introduce a sparse and symmetric matrix completion quasi-Newton model using automatic differentiation, for solving unconstrained optimization problems where the sparse structure of the Hessian is available. The proposed method is a kind of matrix completion quasi-Newton method and has some nice properties. Moreover, the presented method keeps the sparsity of the Hessian exactly and satisfies the quasi-Newton equation approximately. Under the usual assumptions, local and superlinear convergence are established. We tested the performance of the method, showing that the new method is effective and superior to matrix completion quasi-Newton updating with the Broyden–Fletcher–Goldfarb–Shanno (BFGS) method and the limited-memory BFGS method.

Authors: Baek Kiook , Park Jong-Tae , Kwak Kyeongmin
Published: November 2021

The effects of bisphenol A (BPA) on asthma have been reported in various in vitro, animal, and human epidemiologic studies. However, epidemiological studies on the effects of bisphenol S (BPS) and bisphenol F (BPF), which are substitutes of BPA, on asthma are lacking. The purpose of this study was to identify the association between BPA, BPS, and BPF and asthma. An asthma-related questionnaire; urinary BPA, BPS, BPF; and the possible confounders were analyzed among 922 adolescents aged 12–17 years who participated in the Korean National Environmental Health Survey 2016. In males, urinary BPA, BPS, and BPF did not show a significant relationship with the lifetime prevalence of asthma. In females, urinary BPS was higher in the asthma group (p < 0.01). High urinary BPS showed a significant relationship with a high odds ratio (OR) of lifetime asthma prevalence in the model adjusted for possible confounders (p < 0.05). High urinary BPS was particularly associated with an increase in the OR of asthma diagnosed after the age of 60 months (p < 0.01). Urinary BPS was significantly associated with asthma diagnosis, especially after the age of 60 months, among Korean adolescent females.

Published: November 2021

The study examined 110 samples of baby products based on rice, wheat, maize and multi-grains available on the western Polish market in order to detect the level of deoxynivalenol (DON) by means of HPLC (high-performance liquid chromatography) with a fluorescence detector (HPLC-FLD). DON was detected in 9.09% of the infant food samples, with an average and maximum level of 107.8 ± 30 and 148 μg/kg, respectively. The highest concentration of DON was detected in food for infants: wheat-based (mean 121 ± 7.07, 4.8%), multi-grain (mean 118 ± 5.65, 4.25%) and maize-based (mean 100 ± 37.96; 35.30%). No high DON content and high estimated daily intake were observed in the analyzed products. However, in order to minimize the harmfulness associated with the presence of DON in food for infants and young children, a risk assessment should be performed based on the monitoring results.
Role of Sesamia nonagrioides and Ostrinia nubilalis as Vectors of Fusarium spp. and Contribution of Corn Borer-Resistant Bt Maize to Mycotoxin Reduction
Authors: Arias-Martín María , Haidukowski Miriam , Farinós Gema P. , Patiño Belén
Published: November 2021

Maize expressing Cry1Ab insecticidal toxin (Bt maize) is an effective method to control Sesamia nonagrioides and Ostrinia nubilalis, the most damaging corn borers of southern Europe. In this area, maize is prone to Fusarium infections, which can produce mycotoxins that pose a serious risk to human and animal health, causing significant economic losses in the agrifood industry. To investigate the influence of corn borer damage on the presence of Fusarium species and their mycotoxins, Bt maize ears and insect-damaged ears of non-Bt maize were collected from commercial fields in three Bt maize growing areas in Spain, and differences in contamination were assessed. Additionally, larvae of both borer species were collected to evaluate their role as vectors of these molds. Non-Bt maize ears showed significantly higher presence of F. verticillioides, F. proliferatum, and F. subglutinans than Bt maize ears. For the first time, Fusarium species have been isolated from larvae of the two species. The most frequently found mycotoxins in ears were fumonisins, with non-Bt ears being significantly more contaminated than those of Bt maize. High levels of fumonisins were shown to correlate with the occurrence of corn borers in the ear and the presence of F. verticillioides and F. proliferatum.
Stephan Oroszlan and the Proteolytic Processing of Retroviral Proteins: Following A Pro
Authors: Swanstrom Ronald , Sundquist Wesley I.
Published: November 2021

Steve Oroszlan determined the sequences at the ends of virion proteins for a number of different retroviruses. This work led to the insight that the amino-terminal amino acid of the mature viral CA protein is always proline. In this remembrance, we review Steve’s work that led to this insight and show how that insight was a necessary precursor to the work we have done in the subsequent years exploring the cleavage rate determinants of viral protease processing sites and the multiple roles the amino-terminal proline of CA plays after protease cleavage liberates it from its position in a protease processing site.
COVID-19 Anosmia: High Prevalence, Plural Neuropathogenic Mechanisms, and Scarce Neurotropism of SARS-CoV-2?
Authors: Liang Fengyi , Wang De Yun
Published: November 2021

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative pathogen of coronavirus disease 2019 (COVID-19). It is known as a respiratory virus, but SARS-CoV-2 appears equally, or even more, infectious for the olfactory epithelium (OE) than for the respiratory epithelium in the nasal cavity. In light of the small area of the OE relative to the respiratory epithelium, the high prevalence of olfactory dysfunctions (ODs) in COVID-19 has been bewildering and has attracted much attention. This review aims to first examine the cytological and molecular biological characteristics of the OE, especially the microvillous apical surfaces of sustentacular cells and the abundant SARS-CoV-2 receptor molecules thereof, that may underlie the high susceptibility of this neuroepithelium to SARS-CoV-2 infection and damages. The possibility of SARS-CoV-2 neurotropism, or the lack of it, is then analyzed with regard to the expression of the receptor (angiotensin-converting enzyme 2) or priming protease (transmembrane serine protease 2), and cellular targets of infection. Neuropathology of COVID-19 in the OE, olfactory bulb, and other related neural structures are also reviewed. Toward the end, we present our perspectives regarding possible mechanisms of SARS-CoV-2 neuropathogenesis and ODs, in the absence of substantial viral infection of neurons. Plausible causes for persistent ODs in some COVID-19 convalescents are also examined.
Catchment Scale Evaluation of Multiple Global Hydrological Models from ISIMIP2a over North America
Authors: Troin Magali , Arsenault Richard , Fournier Elyse , Brissette François
Published: November 2021

A satisfactory performance of hydrological models under historical climate conditions is considered a prerequisite step in any hydrological climate change impact study. Despite the significant interest in global hydrological modeling, few systematic evaluations of global hydrological models (gHMs) at the catchment scale have been carried out. This study investigates the performance of 4 gHMs driven by 4 global observation-based meteorological inputs at simulating weekly discharges over 198 large-sized North American catchments for the 1971–2010 period. The 16 discharge simulations serve as the basis for evaluating gHM accuracy at the catchment scale within the second phase of the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP2a). The simulated discharges by the four gHMs are compared against observed and simulated weekly discharge values by two regional hydrological models (rHMs) driven by a global meteorological dataset for the same period. We discuss the implications of both modeling approaches as well as the influence of catchment characteristics and global meteorological forcing in terms of model performance through statistical criteria and visual hydrograph comparison for catchment-scale hydrological studies. Overall, the gHM discharge statistics exhibit poor agreement with observations at the catchment scale and manifest considerable bias and errors in seasonal flow simulations. We confirm that the gHM approach, as experimentally implemented through the ISIMIP2a, must be used with caution for regional studies. We find the rHM approach to be more trustworthy and recommend using it for hydrological studies, especially if findings are intended to support operational decision-making.

Research at CV. Solusi Prima was done to help implement chatbot on bug report, in order to solve some problems in interaction with client. We use some research method such as observation, interview, and library research. From this research's result there are some problem with working system that is client and staff in terms of report bug, make report which is done separately and manually (via whatsapp). This matter make staff become confused between chat to see report bug and for staff to make report bug for their head manager, and for head manager it's cost a lot of time to recap all of his staff's works in patch bug. Especially if their customer and the staff keep report error numerously, can cause older report bugs not being recorded in system, or some report being recorded but not tidy enough, so the staff will get confused to input report bug one by one, because of that we use this chatbot system based on natural language processing method with messenger application (telegram).Aim to make it easier for staff and client in making bug reports, so no need for staff to make report manually without having to lose previously datas, other than that the data that is display base on realtime so whatever report that is display will automatically broadcasted by system to all company's staffs from the results of the testing, system worked is compatible with what we are planning from the start. With the use of chatbot that have been equipped with natural language processing, make user easier to do reporting without moving their hands from keyboard to mouse too often. All the informations in chatbot will be saved and can be used for doing data analythic, so making chatbot easier to use and making it easy for staff and client to report a bug.

Published: November 2021

The Helpdesk or Customer Service division in providing information and assistance that related to course services at Stephen Komputer Jambi is currently still using a conventional system, such as services by phone or in person. Likewise, the reservation system or course class registration is still adopting the same system. This conventional service will certainly take a lot of time and money for both the customer and the company, where telephone service will certainly take up time and allow queues to occur. Customer service has limitations in serving customers because it can only serve during working hours and a limited number of personnel. Chatbot is an application that designed to communicate with machines. The Chatbot application is expected to be able to replace the role of customer service to be able to respond to customers more quickly, be able to serve several customers simultaneously and not be fixated on working hours. This application was built using an expert system with the forward chaining method. The final result of this research is a chatbot application that can serve customers in terms of information, assistance and course class reservations at Stephen Computer Jambi.

Post-Pandemic Futures and the Affective Appeal of Immunity
Authors: Oikkonen Venla
Published: November 2021

The COVID-19 pandemic has opened up futures for debate in an unprecedented manner and on an unforeseen scale. This article explores how ideas of immunity structured debates about pandemic management strategies as a means of securing a post-pandemic future during the first wave of the pandemic in 2020. Building on queer theorization of temporality, the article asks how ideas of COVID-19 immunity derive their affective appeal and cultural legitimacy, and what is at stake in the imagined futures that unfold from such visions of post-pandemic immunity. The analysis focuses on two affective figures that circulated widely

in public discourse in March–May 2020: the figure of the soon-immune nation and the figure of the immune individual. I unsettle these figures by contextual- izing them through the histories of immunity politics around race, gender and sexuality. The analysis shows that the two figures have long affective histories entangled with nationalism, racism and discrimination. The article argues that these histories shape and curtail the kinds of post-pandemic futures that may be enacted and imagined through popular ideas of immunity.

Background

A renewed interest for activity and chronicity indices as predictors of lupus nephritis (LN) outcome has emerged. Revised National Institutes of Health activity and chronicity indices have been proposed to classify LN lesions, but they should be validated by future studies. The aims of this study were (1) to detect the histologic features associated with the development of kidney function impairment (KFI), and (2) to identify the best clinical-histologic model to predict KFI at time of kidney biopsy.

Methods

Patients with LN who had more than ten glomeruli per kidney biopsy specimen were admitted to the study. Univariate and multivariate logistic regression and Cox proportional hazards models were used to investigate whether activity and chronicity indices could predict KFI development.

Results

Among 203 participants with LN followed for 14 years, correlations were found between the activity index, and its components, and clinical-laboratory signs of active LN at baseline. The chronicity index was correlated with serum creatinine. Thus, serum creatinine was significantly and directly correlated with both activity and chronicity indices. In the multivariate analysis, glomerulosclerosis (OR, 3.05; 95% CI, 1.17 to 7.91; P=0.02) and fibrous crescents (OR, 6.84; 95% CI, 3.22 to 14.52; P<0.001) associated with either moderate/severe tubular atrophy (OR, 3.17; 95% CI, 1.04 to 9.64; P=0.04), or with interstitial fibrosis (OR, 2.36; 95% CI, 1.05 to 5.32; P=0.04), predicted KFI. Considering both clinical and histologic features, serum creatinine (OR, 1.68; 95% CI, 1.31 to 2.15; P<0.001), arterial hypertension (OR, 4.64; 95% CI, 1.90 to 11.32; P<0.001), glomerulosclerosis (OR, 2.12; 95% CI, 1.00 to 4.50; P=0.05), and fibrous crescents (OR, 5.18; 95% CI, 2.43 to 11.04; P<0.001) independently predicted KFI. Older age (P<0.001) and longer delay between clinical onset of LN and kidney biopsy (P<0.001) were significantly correlated with baseline chronicity index.

Conclusions

The chronicity index and its components, but not the activity index, were significantly associated with an impairment of kidney function. The Cox model showed that serum creatinine, arterial hypertension, chronic glomerular lesions, and delay in kidney biopsy predicted KFI. These data reinforce the importance of timely kidney biopsy in LN.
БРЕНД НАУКОВО-ПЕДАГОГІЧНОГО ПРАЦІВНИКА ЗВО ЯК ТРЕНД СУЧАСНОСТІ
Authors: Юник І. Д.
Published: November 2021

У статті наголошено на потребі суспільства у цілеспрямованому формуванні бренду науково-педагогічного працівника ЗВО як одного з провідних процесів, здатних задовольнити сучасні вектори розвитку української освітньої парадигми – посилення конкуренції на міжнародному та вітчизняному рівні, впровадження в освітній процес новітніх інформаційних технологій та зростання мобільності науково-педагогічних працівників. Обґрунтовано недоцільність ототожнення бренду науково-педагогічного працівника та бренду закладу вищої освіти, оскільки їх склад і комбінаторика структурних компонентів суттєво відрізняються. Запропоновано розгляд феноменології бренду науково-педагогічного працівника ЗВО у шести взаємопов’язаних аспектах: функціональному, економічному, комунікативному, психологічному, соціально- лояльнісному та культурно-етичному. Функціональний аспект бренду науково- педагогічного працівника ЗВО передбачає реалізацію функції підвищення конкурентоспроможності. Економічний аспект бренду науково-педагогічного працівника ЗВО полягає у незаперечності підпорядкування сучасної вищої освіти законам ринкової економіки. Комунікативний аспект бренду науково-педагогічного працівника ЗВО простежується в необхідності уникнення інформаційного вакууму в сфері вищої освіти та передбачає обов’язкове врахування специфічних характеристик освітніх послуг – їх невідчутності та відтермінованості прояву результатів у практичному застосуванні. Доцільність виділення психологічного аспекту бренду науково-педагогічного працівника ЗВО обґрунтовується сутністю бренду як нематеріального активу, оцінці якого цільовою аудиторією передує ряд психічних процесів. У статті акцентовано увагу на можливості сформованого бренду науково- педагогічного працівника виступати гарантією його компетентності, високих морально- вольових якостей, дисциплінованості, відповідальності та інших переваг перед конкурентами на запропоновану посаду, яку доцільно екстраполювати в теорію психологічного контракту. Соціально-лояльнісний аспект бренду науково- педагогічного працівника ЗВО полягає у його здатності набувати довгострокової важливості для цільової аудиторії та прямо корелює з комунікативним аспектом через виконання орієнтувальної функції. Культурно-етичний аспект бренду науково- педагогічного працівника ЗВО стосується притаманних сучасному суспільству процесів раціоналізації та уречевлення особистості й актуалізує необхідність уникнення одновекторного впливу цінностей бренду науково-педагогічного працівника на майбутніх фахівців в рамках простору бренд-комунікації. Доведено, що бренд науково-педагогічного працівника ЗВО є трендом сучасності, який забезпечує підвищення конкурентоспроможності як самого фахівця, так і закладу вищої освіти. Передбачено можливість корекції чи доповнення вищевикладених аспектів розгляду досліджуваного феномену внаслідок зміни наукової парадигми у його вивченні.
ВЕРБАЛІЗАЦІЯ СОЦІАЛЬНО-ПСИХОЛОГІЧНОГО ФЕНОМЕНА МЕДІАОБРАЗІВ У ДИСКУРСІ СУЧАСНОЇ УКРАЇНСЬКО- Й РОСІЙСЬКОМОВНОЇ ГАЗЕТИ: АКТУАЛІЗАЦІЯ АСОЦІАТИВНИХ ЗВ'ЯЗКІВ

У наш час газетний дискурс найбільш послідовно відображає рівень духовності нації, її спосіб мислення. Актуалізація вторинних засобів номінації – постійна мовна тенденція, що демонструє прагнення до виразності, конденсації інформації та привабливості медіатексту. Комбінаторність лексем зумовлена набором певних семантичних і прагматичних стереотипів, які демонструють, що повсякденна свідомість мовця базується на асоціаціях, а не на енциклопедичних знаннях. Під час моделювання медіаобразів політиків, а також вербалізації процесів та явищ, що проявляються в сукупності фрагментів медіа-дискурсу, виникають концептуалізовані метафори, які розглядаємо як соціально-психологічний феномен
ПРО ДЕЯКІ ОСОБЛИВОСТІ СОНЕТНОГО ВІРША ІВАНА ФРАНКА
Authors: Мойсієнко А. К.
Published: November 2021

Стаття присвячена сонетній творчості І. Франка, зокрема ролі поета в оновленні традиції сонетного вірша. На власне мовному рівні в поетиці Франкових текстів означено ряд явищ, традиційно застережених щодо сонетного вірша, це насамперед повтори тих самих слів, іноді цілих рядків у риторичних та риторично-запитальних реченнях, незавершеність фрази з перенесенням у наступний рядок (анжамбеман) тощо. Розглянуто деякі структурно-композиційні особливості сонетних творів автора. І. Франко, культивуючи сонетний вірш як поет, водночас немало зробив для дослідження його як теоретик, літературознавець, перекладач (сонети Данте, Шекспіра). Сонетна творчість Івана Франка є не лише вершинною віхою здобутків українського сонету наприкінці ХІХ-го століття, а й своєрідним підмурівком для подальших новітніх пошуків у цьому жанрі.
