Authors: Winanda Denis Kurniawan  , Budi Widodo  , Betty Agustina
Published: July 2022

Highlights:
1. The Child-Pugh score is an instrument to assess the degree of severity and prognosis of chronic liver disease. 2. the rise in APRI score may predict the advance of cirrhosis stages.
Abstract:
Background: Simple diagnostic and screening methods are needed to assist with liver biopsy, which is not always available in local health facilities. Objective: To assess the AST-to-Platelet Count Index (APRI) as a means to predict the advance of cirrhosis stages as indicated in Child-Pugh classification. Material and Method: This research employed an observational descriptive study design to examine laboratory values such as serum AST and platelet count, which were then compared to Child-Pugh profiles among cirrhosis patients at an inpatient facility in a tertiary hospital of Dr Soetomo General Academic Hospital, Surabaya, Indonesia on 1 January – 31 December 2015. The sampling method for this research was total sampling from medical histories. Result: Data obtained were then analyzed and tabulated using the descriptive technique. As many as 191 samples were obtained, consisting of male (N=129, 67.54%) and female patients (N=62, 32.46%) with a ratio of 2.08:1. APRI score showed an increase in age, with a peak frequency of 68 patients (35.6%) in the range 50-59 years old. Male patients had a higher average APRI score (2.11) than their female counterparts (1.93). Patients from Child C were the majority in this research, consisting of 105 patients (54.9%), followed by Child B (N=65, 34.03%) and A (N=21, 10.9%). Conclusion: The proportion of patients with APRI score > 1.5 is increasing along with the degree of severity according to the Child-Pugh classification. This indicates that the rise in APRI score may predict the advance of cirrhosis stages.

A COVID-19 fertőzés jelentős mértékben hatott a lakosság mindennapi életvitelére, melynek oka elsődlegesen a járványellenes megszorító intézkedések voltak. Előtérbe kerültek az egészséget védő tényezők, melyek közül az egészséges táplálkozásnak kiemelt szerepe van az emberi szervezet kórokozókkal szembeni ellenállás fokozásában.  Ezen kívül a túlsúly kedvezőtlenül befolyásolja a betegség lefolyását, így társadalmunkra még nagyobb veszélyt jelent a vírus. Célunk volt vizsgálni, hogy milyen változásokat hozott a pandémia a mindennapi étkezésünkben, kiemelten a zöldség és gyümölcs fogyasztást. Az adatgyűjtés során szekunder és primer kutatást is végeztünk. Primer vizsgálatunkat online kérdőív segítségével végeztük, melyre 242 válasz érkezett. Megállapítottuk, hogy a megkérdezettek felénél változtak a táplálkozási szokások és egy harmada plusz kilókkal küzd a pandémia alatt. Nagyobb százalékban gondolják azt, hogy elegendő zöldség/gyümölcs fogyasztásuk, míg a napi ajánlott mennyiség bevitele már csak 29,6%-ra jellemző. Az eredmények rámutatnak arra, hogy a napi ajánlott zöldség/gyümölcs mennyiségével nincsenek tisztába a megkérdezettek, amely az egészséges táplálkozás szempontjából is alapvető problémaként tekinthető.

The influence of cognitive biases on investor decision-making: the moderating role of demographic factors
Authors: Syarkani Yofy , Alghifari Erik Syawal
Published: July 2022

Purpose – This study aims to see investor behavior in making investment decisions influenced by cognitive biases, namely overconfidence bias and the illusion of control bias by looking at the situational factors such as age, gender, and education.
Design/methodology/approach – This study is conducted using a quantitative method by distributing a questionnaire. The questionnaires are measured using a 5-point Likert scale. The samples are taken from the population of individual investors in Bandung, West Java, with a number of 100 respondents.
Findings – The results of this study prove that: (1) Illusion of control bias has an influence on investors’ decision-making, (2) Gender and education moderates the influence between the illusion of control bias on investor decision-making, (3) Age does not moderate the influence between the illusion of control bias on investor decision-making, (5) Overconfidence bias has an influence on investor decision-making, (6) Gender moderates the influence between overconfidence bias on investor decision-making, and (7) Age and education do not moderate the influence between overconfidence bias on investor decision-making.
Research limitations/implications – The population in this study is limited to individual investors in Bandung. Future studies can conduct research in a similar direction using other populations, or focusing on a certain population, to ensure the generalizability of the results.
Practical implications – Investors should be aware of cognitive biases while making decisions to invest. The biases can occur whether the investors realize it or not. Therefore, it would be useful for them to understand their cognitive biases so that investors can act rationally while making investment decisions.
Originality/value – This study fills the research gap from the previous studies by examining the differences of investors' decision-making based on demographic factors, which are used as the moderating variables.
Job insecurity to counter productive work behavior moderated leader-member exchange
Authors: Siswanti Yuni
Published: July 2022

Purpose – This study aims to find out and analyze the influence of job insecurity on counterproductive work behavior (CWB) and test the quali­ty of LMX as a variable moderation in employees in the creative culinary in Sleman Regency Yogyakarta.
Design/Methodology/Approach – The type of research used in this study is explanatory with a quantitative approach. The population of this study is employees in 18 creative industries in the culinary field in Sleman Regency, Yogyakarta. One hundred twenty-two respondents took the sample by the purposive method. The instrument Test used validity and reli­ability. Hypothesis testing uses simple regression and moderated regression.
Findings – Results show that job insecurity significantly affects coun­terproductive work behavior (CWB). LMX quality moderates the effect of job insecurity on CWB. The results of this study have theoretical and managerial implications and require further research.
Research Limitation/Implications – This study has limitations, namely: population collection is still minimal because SMEs are studied in only one district, the type of SMEs business and limited to culinary, cross-sectional data collection. Further research should be expanded in the scope of the population, not only in one district but expanded in other districts in Yogyakarta. The type of product produced by respond­ents in this study is the culinary field, so it should be extended to different SMEs types. Second, cross-sectional data collection of this study requires a more longitudinal design in the future to get better study results. Third, the study did not distinguish CWB in workers with permanent employee status and workers with contract employee status.
Practical Implications – Providing understanding to culinary SMEs to maintain good relations with all workers in the form of respecting work­ers, respect for the work of the men, establishing effective communica­tion with workers under any conditions, trying their best for their men, and increasing the sense of belonging in the men.
Theoretical Implications – Academics and researchers have a perceptual understanding of the contribution of leader-member relationships (LMX) in lowering the influence of job insecurity on CWB (CWB-O) and (CWB-I).
Originality/Value – Authenticity of the study: Previous research that included LMX quality as a moderation variable between job insecurity and CWB is still very minimal. It shows that the theory reinforces the existence of LMX Theory that the high quality of LMX between leader-members has been characterized by an exchange of emotions based on mutual trust and respect. In contrast, the low quality of LMX relation­ships has the characteristics of economic exchange.

Published: July 2022

In the context of an evolving digital environment of library education, it is important to study the needs and expectations of students as participants of the educational process and the direct consumers of educational services. This paper presents the results of a questionnaire survey of students studying on the specialty “Library and Information Activities” at the Belarusian State University of Culture and Arts. The objective of the survey was to determine the students’ vision of new trends in educational practice and the prospects for the development of library education associated with digitalization. The study was conducted by the working group as a part of the contract research “Explore trends and ways of development of library and information education in the digital age”. The survey touched upon such research areas as a promising vector for the development of library education, students’ readiness for library activities in a digital environment, and the use of information and communication technologies in the learning process. It was found that the students consider the information and technological courses as a promising vector for the development of library education (information courses as the basis for training). In the courses taught at the Faculty of Information and Document Communications, students would like to focus on remote user service, programming, data analytics, digital technologies, neural networks, nanotechnologies, digital marketing, web design basics, the creation and design of electronic resources, the basics of working with graphic editors and other. Assessing the importance of various types of library work in the digital environment, students marked “Working with electronic catalogs and databases” as the most important one. Least of all, students consider themselves ready for the “Work to create electronic information resources” and “Work to provide access to electronic information resources”. In the process of distance learning during the epidemic COVID-19, the greatest difficulty was the increase of the workload, the complication of the learning process. Of less significance were the technical communication problems. А set of measures from the viewpoint of students to improve the quality and competitive advantages of library and information education in the digital age is defined.

The discussion reflects the points of view of doctors of sciences from the Russian State Library, the Russian National Library, the Saint-Peterburg State Institute of Culture and the State Public Scientific and Technical Library of the Siberian Branch of the Russian Academy of Sciences (SPSTL SB RAS), voiced on March 16, 2022 at the round table “Science in Libraries”. The round table was held within the framework of the international conference “Libway” held by the SPSTL SB RAS. The participants of the discussion answered the following questions: general assessment of the state of domestic library science, book science, bibliography; key areas of library science, book science and bibliography in the second decade of the 21st Century; problems of scientific personnel training; the place of library science and the prospects for its development within the new Nomenclature of scientific specialties. The discussion made it possible to single out the following problems: the importance of solving practice-oriented problems of library science and bibliography, and only then their theoretical analysis and generalization; work in the library field of specialists from other industries with a poor understanding of librarianship and bibliography issues; lack of educational and methodological materials for graduate students and their supervisors; a very small number of state-funded places in graduate school and the lack of material incentives to attract specialists to scientific research. In a general assessment of the state of the disciplines of the documentary and communication cycle, opinions differed – from an optimistic view of the future of these disciplines to a pessimistic one due to the presence of numerous internal problems. The necessity of collaboration is stressed. All participants expressed their deepest satisfaction with the inclusion of library, bibliography and book sciences in the new Nomenclature of scientific specialties and the emergence of a new specialty passport.
Functional Structure of Tomsk Library Science Museum’s Book Collection (1919–1921)
Authors: Nikienko I. V.
Published: July 2022

The paper deals with the principles of the book fund organization in Library Science Museum (1919–1921), created by the future famous library scientist and bibliologist D. A. Balika during his professional formation in Tomsk. The Museum was created for didactic and methodological support of library professional education. The author shows the functional structure of the book collection and gives comments on possible dynamics of its composition, describes the methods to identify the source books and the sample books basing on the features of their publishing and printing form and various aspects of content (affiliation to a particular branch of knowledge, psychological type). She characterizes the ways to use two mentioned types of editions in educational process. (That is for the formation of knowledge and skills in library science, book studies, author studies and reader studies in a passive or active way – by the assimilation of the source books’ content or by the analytical description of the sample books). The author traces the biblio-psychological (Rubakin’s) traditions and biblio-pedagogic innovations in D. A. Balika’s vision of librarian’s “inner work” (“reading guidance” within the framework of the extracurricular education program). The transformation technology of a non-specialized fund into an educational one implemented by D. A. Balika seems to be relevant nowadays due to the strengthening (restoration) of the reader focus in the programs of higher library education in Russia and Ukraine at the beginning of the XXI century.
Tools and Data Towards Supporting Quantitative Systems Pharmacology of the Eye – An Overview
Authors: Kuepfer Lars , Fuellen Georg , Stahnke Thomas
Published: July 2022

Good eyesight belongs to the most-valued attributes of health, and diseases of the eye are a significant health care burden. Case numbers are expected to further increase in the next decades due to an aging society. The development of drugs in ophthalmology, however, is difficult due to limited accessibility of the eye, in terms of drug administration and in terms of sampling of tissues for drug pharmacokinetics (PK) and pharmacodynamics (PD). Ocular quantitative systems pharmacology (QSP) models provide the opportunity to describe the distribution of drugs in the eye as well as the resulting drug-response in specific segments of the eye. In particular, ocular physiologically-based pharmacokinetic (PBPK) models are necessary to describe drug concentration levels in different regions of the eye. Further, ocular effect models employing molecular data from specific cellular systems are needed to develop dose-response correlations. We here describe the current status of PK/PBPK as well as PD models for the eye and describe cellular systems, data repositories as well as animal models in ophthalmology. The application of the various concepts is highlighted for the development of new treatments for post-operative fibrosis after glaucoma surgery.

Background. Telegram, an Industry 4.0 style Russian-born communication service, is one of the world’s most widespread communication platforms despite Putin’s censorship. The availability of channels and bots has opened as a broadcast channel for any media outlet. Objetives. We asked the following questions: Do Spanish media outlets use Telegram channels? Which media outlets? Are they verified? What is their volume of subscribers? Can this information be used to rank media outlets? We identified many media channels and numerous variables were collected from each one. Results and conclusions. Forty-two Spanish media outlets have Telegram channels, 26 of which are ranked in the directory. Less than half of these channels are verified by the platform, and only three are linked to their website. This lack of verification could lead to the proliferation of fake channels. We created a ranking, and the top-10 includes two foreign, six national, and two regional media outlets.

Digitalization of Legacy Datasets and Machine Learning Regression Yields Insights for Reservoir Property Prediction and Submarine-Fan Evolution: A Subsurface Example From the Lewis Shale, Wyoming
Authors: Martin Thomas , Tadla Jared , Jobe Zane
Published: July 2022

Machine-learning algorithms have long aided in geologic property prediction from well-log data, but are primarily used to classify lithology, facies, formation, and rock types. However, more detailed properties (e.g., porosity, grain size) that are important for evaluating hydrocarbon exploration and development activities, as well as subsurface geothermal, CO2 sequestration, and hydrological studies have not been a focus of machine-learning predictions. This study focuses on improving machine-learning regression-based workflows for quantitative geological property prediction (porosity, grain size, XRF geochemistry), using a robust dataset from the Dad Sandstone Member of the Lewis Shale in the Green River Basin, Wyoming.

Twelve slabbed cores collected from wells targeting turbiditic sandstones and mudstones of the Dad Sandstone member provide 1212.2 ft. of well-log and core data to test the efficacy of five machine-learning models, ranging in complexity from multivariate linear regression to deep neural networks. Our results demonstrate that gradient-boosted decision-tree models (e.g., CatBoost, XGBoost) are flexible in terms of input data completeness, do not require scaled data, and are reliably accurate, with the lowest or second lowest root mean squared error (RMSE) for every test. Deep neural networks, while used commonly for these applications, never achieved lowest error for any of the testing. We also utilize newly collected XRF geochemistry and grain-size data to constrain spatiotemporal sediment routing, sand-mud partitioning, and paleo-oceanographic redox conditions in the Green River Basin.

Test-train dataset splitting traditionally uses randomized inter-well data, but a blind well testing strategy is more applicable to most geoscience applications that aim to predict properties of new, unseen well locations. We find that using inter-well training datasets are more optimistic when applied to blind wells, with a median difference of 0.58 RMSE when predicting grain size in phi units. Using these data and results, we establish a baseline workflow for applying machine-learning regression algorithms to core-based reservoir properties from well-log and core-image data. We hope that our findings and open-source code and datasets released with this paper will serve as a baseline for further research to improve geological property prediction for sustainable earth-resource modeling.
Methods to Enhance Success of Field Application of In-Situ Combustion for Heavy Oil Recovery
Authors: Harding Thomas
Published: July 2022

While much has been learned in the laboratory over the past four decades about the in-situ combustion (ISC) process, especially through carefully conducted physical model experiments, and many advancements in numerical simulation capability have been achieved, successful field application of ISC remains a rarity. This paper discusses challenges that have been faced in moving from laboratory to field and some strategies that may be used for improving the success rate. There is a brief discussion of the advantages and disadvantages of ISC as a recovery method and comparisons with steam injection, which is the dominant thermal recovery method used in the field. A discussion of the challenges and progress made in numerical simulation is provided with the suggestion that such mathematical modeling can now be a useful tool in designing field projects and can increase the probability of success. The needs of industry to operate safe, simple, and economically and environmentally sustainable projects are discussed along with the currently negative perception of the ISC process in industry. The paper makes some suggestions regarding how to address these issues. The main thesis of this paper is that air injection into a reservoir introduces a large amount of nitrogen that is detrimental to the displacement of oil, and oil recovery yet offers few, if any, advantages. Reducing the amount of noncondensable gas (NCG) associated with the process can be done mainly in two ways—by using oxygen-enriched air injection and furthermore by injecting a mixture of steam and oxygen-enriched air. The paper does not make a comprehensive review of past field projects but does include a summary of promising areas for future application of the ISC combustion recovery process.

Published: July 2022

Low-Energy Processes for Unconventional Oil Recovery fills a gap in oil and gas literature. Today, in our globalized society, the oil industry has to demonstrate how oil recovery can be done responsibly over the life-cycle of the project, clearly articulating energy efficiency as well as limiting CO2 and environmental footprints of the chosen recovery processes. The authors bring together their complementing expertise to provide the reader with an in-depth discussion of a range of alternative recovery techniques. Most recovery methods included are focused on heavy oil recovery, but some have applications in light oil reservoirs as well. With the recent industry drive and focus to recover hydrocarbons from tight rock and shale resources, a chapter has also been devoted to shale oil recovery.

Published: July 2022

Reservoir simulation has been in practice for more than 50 years, but it has recently gained significant momentum because of its wider application to the increasingly complex reservoir systems of today. Reservoir Simulation: Problems and Solutions provides petroleum engineers with extensive practice in the art of problem solving, strengthening their critical-thinking solution strategies, and preparing them for the unique problems they will encounter in this dynamic field. Built on the fundamental concepts and solutions of the original exercises found in Basic Applied Reservoir Simulation (Turgay Ertekin, Jamal H. Abou-Kassem, and Gregory R. King), this new book provides an additional 180 exercises and solutions that fully illustrate the intricacies of reservoir-simulation methodology.

IntroductionTo assess differences in cerebral cortex structure changes between lung cancer and healthy controls, and to analyze their correlation with cognitive function.Methods33 patients diagonosed with primary lung cancer have been enrolled in a prospective study. Before starting treatment and 2–4 months after recieving treatment, the patients underwent assessment of cognitive function, and activities of daily living, as well as a T1-weighted magnetic resonance imaging. The patients were compaired with 33 sex, age and education-matched healthy controls.ResultsNeuropsychological assessment, MoCA and Tail Making Test (TMT), shows that 78.8% of newly diagnosed lung cancer patients had mild to moderate cognitive impairment. Patients' visual space and executive ability deteriorated after treatment (t = 2.66, d = 0.66, P = 0.02). At baseline, some cerebral cortex of frontal, temporal and parietal lobes were atrophied, especially anterior central gyrus, rostral middle frontal cortex, superior temporal gyrus, middle temporal gyrus and temporal pole. After treatment, the rostral middle frontal cortex of the right brain was further atrophied (P<0.005). There was a positively correlation between atrophied cortical thickness in newly diagnosed lung cancer patients and the score of part A of TMT. Temporal pole volume was positively correlated with naming (r = 0.39, P = 0.03) and language (r = 0.43, P = 0.02), while middle temporal gyrus was positively correlated with attention (r = 0.39, P = 0.03) and orientation (r = 0.39, P = 0.04).ConclusionThis study suggests that cancer itself and treatment lead to cognitive impairment, as well as cortical thickness and volume reduction, and cerebral cortex structure changes are correlated with cognitive function. Confirming the existence of cancer-related cognitive impairment and cancer-related brain injury.

Background Surgical site infection (SSI) and antimicrobial resistance may adversely affect the clinical outcome of older patients. Objective Investigate the etiology and outcome of SSIs in elderly patients who underwent emergency bowel surgery. Methods We conducted a retrospective study of all patients aged ≥60 years who underwent emergency surgery due to an ileus from January 2014 to June 2019 in a tertiary teaching hospital in Western China. Demographic data, comorbidities, perioperative physiological and microbiological data, and information on the surgical technique and duration of hospitalization were extracted from clinical records to assess risk factors for SSIs. Results Of 125 patients included, 115/125 (92%) had a duration of >48 hours postoperative prophylactic antibiotic use; 37 (29.6%) patients were diagnosed with SSI. All occurred within the period of postoperative antimicrobial prophylaxis or after an extended duration of >48 hours prophylactic antibiotic use. Enterobacteriaceae and Enterococcus were the most frequently isolated species (67.4% and 20.9%, respectively): 93.8% of Escherichia coli (15/16) and 46.2% of other Enterobacteriaceae (6/13) isolated were ceftriaxone-resistant. Incision site classification was an independent risk factor for SSI in multivariate analysis. SSI patients had a significantly longer length of stay than those without (29.81±12.96 days vs. 22.52±10.67 days, respectively; p=0.001). Conclusion Higher rates of extended-spectrum beta-lactamase-producing Enterobacteriaceae carriage were associated with higher SSI, despite prolonged antimicrobial prophylaxis. This calls for the improved surveillance of resistance in order to offer an alternative prophylaxis for the prevention of these types of infections.

Context: Migraine is a disabling condition that is currently underdiagnosed and undertreated. Transcutaneous vagus nerve stimulation (VNS) is among the most researched non-invasive brain stimulation techniques for migraine control. Objectives: In this integrative review, we discuss the effects of VNS parameters (waveform, frequency, intensity, cycle, and current), central, and clinical mechanisms in auricular (taVNS) or cervical (tcVNS) transcutaneous VNS in the control of migraine pain.Methods: PubMed (National Library of Medicine), Cochrane Library, CAPES Journals (Portal of Journals of the Coordination for the Improvement of Higher Education Personnel), Virtual Health Library (VHL), and Google Scholar were searched by computer from the establishment of within the 10-year period (2011–2021). Results: Initially, a total of 10,017 articles were identified. After applying the exclusion criteria, 10,007 articles were excluded. The eligibility criteria were analyzed and only ten articles fulfilled the criteria. The most used parameters in this study for VNS were the frequencies of 1 Hz, 25 Hz, and 30 Hz. The 1 Hz stimulation caused a more significant reduction in the number of days with headache. The total stimulation time varies between studies, ranging from 2 min to 240 min, and can be repeated for a period or a single session. Studies that used a longer treatment period showed clinical results in reducing pain and analyzed the scores. Moreover, studies have shown reduced intensity or severity of pain after taVNS.Conclusions: The studies performed taVNS or tcVNS, and both methods had positive effects on migraine control, pain reduction, and migraine score.
