Published: November 2022

Absensi merupakan bagian yang memegang peranan penting dalam setiap instansi pendidikan. Absensi merupakan salah satu penunjang utama yang dapat mendukung dan memotivasi setiap kegiatan yang dilakukan. Seperti halnya absensi di SMK Media Insan Cendekia yang masih menggunakan cara manual (tanda tangan), cara ini sangatlah rawan bagi suatu lembaga pendidikan karena tingkat kedisiplinan yang tidak dapat dikontrol dan  dapat disalahgunakan oleh orang yang tidak bertanggung jawab. Kerugian lain yang mungkin muncul pada sistem absensi manual adalah rekapitulasi data yang masih memakan banyak waktu dan tenaga. Tujuan penelitian ini adalah merancang dan membangun suatu Sistem Informasi Absensi dengan Kamera yang memudahkan guru, staff dan siswa dalam melakukan proses absensi di sekolah. Metode penelitian yang digunakan adalah metode The Open Group Architecture Framework (TOGAF). Metoda ini hanya terfokus pada fase F (migration plaining) dan fase G (Implementation Governance). Hasil penelitian ini berupa aplikasi yang memanfaatkan kamera HP sebagai komponen utama dalam membantu proses absensi setiap guru, staff dan siswa.

Published: November 2022

The article presents a qualitative assessment of the current accounting system at the enterprises of the Institute of Bioenergy Crops and Sugar Beets of NAAS of Ukraine on the example of Yaltushkiv Experimental Breeding Station.

It has been found that in recent decades, digital transformation has become relevant not only at the enterprise level, but also at the level of individual sectors of the economy and even the state. It is designed to simplify the work with large data sets, automate almost all activities, improve the interaction of citizens with the state, customers with companies, enterprises and the state as a whole.

Peculiarities of the introduction of the modern information technologies for conducting automated accounting at enterprises are investigated. The characteristics of modern software products on the domestic market are given, which allowed to make proposals for the selection of software for automation of accounting at ESIC «Ukrainian Scientific-Educational Consortium» (Yaltushkiv Experimental Breeding Station of the Institute of Bioenergy Crops and Sugar Beets NAAS of Ukraine) in favor of BAS «Accounting».

The importance of the automated form of accounting, which optimizes the work of the accounting department, will ensure the maximum savings of working time, the highest productivity and most importantly – information security of the enterprise. It is noted that the human factor also plays an important role in the development of the digitalization system, as special attention needs to be paid to continuous staff improvement, development and skills development.

Prospects for the use of the domestic software products, which are the basis for creating a highly organized environment, where at a new, high quality level, will be able to conduct daily operations and monitor and analyze the state of the enterprise, which will allow to make the science-based management decisions.
WHAT MONEY WILL BECOME A MAINSTREAM CASH FLOW – ELECTRONIC OR VIRTUAL?
Authors: ZAKHARCHENKO VOLODYMYR
Published: November 2022

The article considers the current issues of monetary circulation in Ukraine and the world in the context of global challenges related to the world financial crisis of 2008-2009, the coronavirus pandemic and the Russian-Ukrainian war. The purpose of the study is a comparative analysis of electronic money, both fiat and virtual, as non-fiat, regarding the possibilities of their transformation into mainstream, that is, to occupy their dominant position in the money circulation systems of Ukraine and the world. It is noted that virtual money is often also called cryptocurrencies, because it is based on the blockchain technology, which provides a cryptographic system for protecting information. It is emphasized that their main technological feature is the decentralized nature of the crypto network. This means that they are not emitted or controlled by the state, and therefore cannot belong to fiat money (as opposed to electronic). Both advantages and disadvantages of virtual money compared to electronic ones have been identified. The presence of such shortcomings in cryptocurrencies, as a significant energy consumption of mining coins, high market volatility, the presence of «bad actors» in crypto networks and the displacement of national currencies, acutely raises questions about their regulation. It is proposed to distinguish between the five models of regulation of cryptocurrencies: repressive (with their complete prohibition); conservative (with the possibility of their purchase and sale in crypto exchangers); liberal (with permits for most operations with them); legal turnover; permitting (with recognition as a means of payment on par with the dollar and other reserve currencies). It is noted that despite the significant restrictions, especially according to the demands of repressive and conservative regulatory models, the cryptosector is rapidly developing both in the world and in Ukraine. As a positive moment in the development of the cryptosector in Ukraine, it is noted that it is already «working» in support of Ukraine in the war with the russian federation. It is concluded that the mainstream of cash flow should be electronic money. Virtual money should not bypass their share in cash and become another reserve currency. Otherwise, it will give cartblanche to transnational capital and undermine the basis of the current world system – the division of the world into separate states.

Published: November 2022

The features of information support of the state of the horticulture industry of Ukraine in the areas of management needs are studied. A review of domestic and foreign scientific sources on the specified issues was carried out, the state of the horticulture industry in Ukraine and Vinnytsia region in the period 2015-2020 was analyzed in terms of production, assortment, balance of fruit and berry crops. In particular, it was determined that the volume of the crop production has increased from UAH 24.31 billion in 2015 to UAH 67.0 billion in 2020. The place of Vinnytsia region in the regional structure of the horticulture industry of Ukraine for 2015-2020 is characterized, the general indicators of the region’s production, financial resources of certain categories of horticultural farms, in particular corporations «Vinnytsiasadvinprom» and the FE «Agro-Sad», are analyzed. The influence of the cost structure on the results of economic activity and the place of sales expenses in the structure of production costs are determined. The basics of normative regulation and strategic documents for the development of the horticulture industry in Ukraine are disclosed. The definition of the information-analytical structure of the functioning of the Ukrainian horticulture industry as a production process, the state of the market, and the information needs of management levels is given. It has been proven that the most important factors influencing the functioning of the horticulture industry are: production efficiency; sales; conditions and volumes of state support, internal and external demand; financing; logistics; inclusion in international infrastructure chains, etc. According to the balance of products of the horticulture industry in Ukraine, it was determined that the growth in production is slow, while production volumes increased only 2 times, imports decreased by 2, the total growth of resources is 73%, exports increased 5 times, and consumption to 46%. State support for the development of viticulture, horticulture and hop growing for 2019-2022 is in the range of UAH 400-490 million, and although this is almost 10% of the agricultural budget, the funds are clearly not enough to manage effectively the sustainable development of the industry. On the basis of the study, the directions of information management needs at the levels of production, processing, export, financing, logistics and activities that contribute to the further development of the Ukrainian horticulture industry are formed.

Published: November 2022

Pre-COVID-19 pandemic, suicide, and suicidal behaviour were serious public health concerns that had a global influence on youth. However, there are concerns about the possible Pandemic-related factors contributing to self-harming thoughts and behaviours. At the same time, the antecedents of self-harm thought have been examined previously; this study aimed at exploring suicidal ideation –the preoccupation to kill oneself — among young adults who are prone to be affected by pandemic-related conditions. This Cross-sectional study investigated the role of sex, psychological distress, and social media addiction in predicting Self-harm thoughts during the COVID-19 pandemic. Three hundred forty undergraduates cutting across the various faculties were conveniently selected from LASU to respond to the standardised questionnaire. It was hypothesised that male undergraduate students would be more susceptible to self-harm thoughts than female undergraduate students, and psychological distress and social media will have an independent and joint influence on Self-harm thoughts. The result revealed that there was a significant influence of sex on self-harm thoughts (t= 2.17; df (340); P <.05). Furthermore, male undergraduate students were more likely to have thoughts of self-harm than female undergraduate students. It was also revealed that psychological distress and social media addiction jointly (R2 = 0.89, F (2,339) = 16.56, p < .05) and independently predicted Self-harm thoughts. The findings suggested that Clinicians and counsellors, when assessing students with thoughts of self-harm, should consider finding out the extent of usage of social media and its addiction as it should be one of the important aspects to look out for during assessment. Additionally, University management should work on novel and practical approaches to detect early symptoms of psychological distress and advance suicide prevention efforts to secure the precious lives of Students

In the recent business environment where the digital transformation makes a value across the industries, the fashion industry also witnessed a variety of business cases which leveraged cutting-edge ICT technologies to increase effectiveness of production and maximize customer experience. But, in the real world, vast majority of fashion companies had a trouble achieving successful digital transformation. In this background, this paper aims to identifying factors influencing successful digital transformation in fashion industry using AHP model. Furthermore, this study evaluate relative importance of two different implementation strategy for digital transformation: (1) Effectiveness of R&D and production (2) Maximizing customer experience. The pannel who answered AHP survey consist of experts in fashion industry and IT industry. As a result of empirical analysis, the most important factor influencing successful digital transformation of fashion industry was organizational culture at the 1st hierarchy of AHP model and the interest and support of TMT(Top Management Team) at the 2nd hierarchy of AHP model, respectively. Finally, in the evaluation of the priority of the implementation strategy, the strategy for maximizing customer experience was found to be slightly higher than the strategy for improving production efficiency. This paper contributes to both academia and practice. To the best of our knowledge, this is the first attempt for quantitatively evaluating importance score of variety factors influencing digital transformation in fashion industry.

Published: November 2022

While the domestic entrepreneurial ecosystem has grown rapidly, the concentration of related social and economic infrastructure in the metropolitan area is deepening. In particular, local entrepreneurship, which can create new jobs in the region and contribute to regional economic growth, plays a key role in alleviating the imbalance between the metropolitan and the region. However, relatively few studies have focused on the regional start-ups. To fill this void, this study examines the antecedents of the survival of local start-ups. Specifically, we examine whether the survival probabilities of start-ups differ by region and which firm and regional characteristics affect the survival of local start-ups. We test these hypotheses by using 44.19 million start-up companies from 2016 to 2019. The findings show that the survival rate of start-ups is different even within the same region. This means that local factors can have a significant impact on the survival of start-ups. Second, our results also indicate that the industrial type and firm size had a significant effect on survival. In addition, as for regional characteristics, it was found that industrial structure, location coeffieicent, diversity index, metropolitan area, and the number of universities have significant impact on the survival of start-ups. Based on these results, we discuss the implications and limitations in this study.
An Empirical Study on Relation between Accounting Earnings-Stock Return Bias and Insider Stock Trade
Authors:   Academic Society of Global Business Administration, Ki Do Hoon , Kim Seung Jun
Published: November 2022

This study analyzes the pre-transaction period accounting earnings-stock price relation among companies with and without insider trade(insider sell and buy) to find out whether information asymmetry increase potential insider’s profit, thereby, motivate insider to trade their own stocks.
In order to figure out correct relationship between insider trading and information asymmetry, this study recognize succesive insider trading, and use only first trade observation of succetive insider sell and buy, respectively. Therefore the total number of stocks and the first trade of each successive insider tradings are respectively presumed as an insider trading volume and as an observation of the the succesive insider trading.
Also, all ownership information of directors and major shareholder is cellected from DART using Python, and quarterly financial information is used for our analysis to alleviate the possible problem coming from assumption of period of insider trading.
The analysis period is from 2012 to 2018, and non-financial companies among listed companies on the Korea Stock Exchange and KOSDAQ are targeted.
Empirical analysis shows as follow.
First, it was found that the greater the over-estimate of earnings-return relation incurs greater probability of occurrence of insider stock sales and greater insider sales stock volume. These relationships are larger and more significant than those between insider trading and future earnings level, future earnings growth, and future stock return, which represent insiders' information advantage on future prospects of the firm. Second, the effect of estimation bias of earnings-return relation on the probability of insider sales was stronger and more immediate than those of insider purchases. The positive relationship between future prospects and insider trading, reported in previous studies, was stronger in insiders purchases than in insider sales.
This study directly analyzed whether information asymmetry between insiders and external stakeholders plays a major role of insider trading, comparing pre-period earning-return relation estimates of insider trading firms with those of control firms. It is also meaningful in that it shows that the information asymmetry difference between insiders and external stakeholders can have different effects on insider trading for different properties of insider sales and purchase.
Ownership-Control Disparity and Investment Efficiency
Authors:   Academic Society of Global Business Administration, Park Bum-Jin
Published: November 2022

While much research has continued to concentrate on finding the determinants of investment efficiency, it has been neglected that investment efficiency may depend on agency problems between controlling shareholders and external stakeholders caused by ownership-control disparity. The purpose of this study is to provide stakeholders with evidence that information asymmetries caused by ownership-control disparity can depreciate investment efficiency by analyzing the relationship between ownership-control disparity and investment efficiency.
From analyses, there is a significant negative relationship between ownership-control disparity and investment efficiency, with this relationship remained unchanged after controlling endogeneity between them. These results show that as ownership-control disparity increases, agency costs produced by deepened information asymmetries lower investment efficiency. Moreover, as ownership-control disparity increases, over investment is not asymmetry to under investment and that is more dominant than under investment. On the other hand, at the low and high levels of ownership-control disparity, although the relationship between ownership-control disparity and investment efficiency are insignificant statistically, this relationship is negative. At the middle level of ownership-control disparity, it appears a significant positive relationship between them, suggesting that there is potential non-linear relationship between them.
Option Pricing by Classical Tempered Stable Lévy Process (or CGMY Model) with Fourier Transformation: Including Merton’s Model and Variance-Gamma Process
Authors:   Academic Society of Global Business Administration, Lee Hong Jae , Kim Tae Seog
Published: November 2022

In the real world, products in the stock market do not generally follow a normal distribution, but are known to follow a fat-tail distribution with high kurtosis and thick tails of skewness. Therefore, the purpose of this study is to analyze option pricing using a distribution in which random variables follow a stable and independent distribution and well represent the properties of the actual distribution. At this time, for the empirical analysis data, 252 daily KOSPI200 closing price indexes were used from November 15, 2019 to November 20, 2020. Call Options(Put options) were set as OTM(ITM) and ITM (OTM) and analyzed.
In the research methodology of this paper, option pricing was performed by the CTS (or CGMY) model assuming a Tempered Stable Distribution that is capable of Furier transformation. In addition, the Black-Scholes model assuming a normal distribution and Fourier transformation, and the Fourier transformation were performed. The option pricing model using the Merton Diffusion Process and Variance-Gamma process was compared and analyzed.

Authors:   Academic Society of Global Business Administration, Cha Dae Kyu
Published: November 2022

This study investigated the effects of ownership structure and ESG performance on investment efficiency. The variable of investment efficiency was measured based on the research results of Biddle et al.(2009), and the study period was from 2013 to 2021. The results of the study are as follows.
First, as a result of empirical analysis of the effect of ownership structure on investment efficiency, the foreign ownership ratio has a positive effect on investment efficiency, and the ratio of largest shareholders also has a positive effect on investment efficiency. It was found that ownership structure had a positive effect on investment efficiency.
Second, as a result of empirical analysis of the effect of ESG performance on investment efficiency, it was confirmed that E performance had a positive effect on investment efficiency, and that 'G' grade also had a positive effect on investment efficiency. However, the 'S' grade did not appear significantly, but when viewed individually, the S grade also appeared to have a positive effect on investment efficiency. Third, as a result of empirical analysis of the effect of the interaction effect of ownership structure and ESG rating on investment efficiency, it was found that the interaction effect between foreign ownership ratio and ‘E’ rating had a positive effect on investment efficiency. Next, it was found that the interaction effect between the largest shareholding ratio and the grade ‘E’ also had a positive effect on investment efficiency. However, it was found that the interaction effect between the major shareholding ratio and the 'S' grade had a negative effect on investment efficiency.
The implications of this study are that the interaction effect of ownership structure and ESG performance, which are major variables affecting investment decision-making, was verified, and it is meaningful in that it can provide external information users with a direction in making investment decisions.

The Arizona Radio Observatory 1 mm Spectral Survey of the Hypergiant Star NML Cygni (215–285 GHz)
Authors: Singh A. P. , Edwards J. L. , Ziurys L. M.
Published: November 2022

A sensitive (1σ rms ≤ 3 mK; 2 MHz resolution) 1 mm spectral survey (214.5–285.5 GHz) of the envelope of the oxygen-rich supergiant star NML Cygni (NML Cyg) has been conducted using the 10 m Submillimeter Telescope of the Arizona Radio Observatory. These data represent the first spectral line survey of NML Cyg and are complementary to a previous 1 mm survey of the envelope of a similar hypergiant, VY Canis Majoris (VY CMa). The complete NML Cyg data set is presented here. In the survey, 104 emission lines were observed, arising from 17 different molecules and 4 unidentified features. Many of the observed features have complex line profiles, arising from asymmetric outflows characteristic of hypergiant stars. While most of the lines in the survey arise from SiO, SO, SO2, and SiS, CO had the strongest emission. Five other C-bearing species are identified in the survey (HCN, CN, HCO+, CS, and HNC), demonstrating an active carbon chemistry despite the O-rich environment. Moreover, NS was observed, but not NO, although favorable transitions of both molecules lie in the surveyed region. Sulfur chemistry appears to be prominent in NML Cyg and plays an important role in the collimated outflows. The refractory species observed, NaCl and AlO, have narrow emission lines, indicating that these molecules do not reach the terminal expansion velocity. NaCl and AlO likely condense into dust grains at r < 50 R
*. From NaCl, the chlorine isotope ratio was determined to be 35Cl/37Cl = 3.85 ± 0.30.

We present the visual orbits of four spectroscopic binary stars, HD 61859, HD 89822, HD 109510, and HD 191692, using long baseline interferometry with the CHARA Array. We also obtained new radial velocities from echelle spectra using the APO 3.5 m, CTIO 1.5 m, and Fairborn Observatory 2.0 m telescopes. By combining the astrometric and spectroscopic observations, we solve for the full, three-dimensional orbits and determine the stellar masses to 1%–12% uncertainty and distances to 0.4%–6% uncertainty. We then estimate the effective temperature and radius of each component star through Doppler tomography and spectral energy distribution analyses. We found masses of 1.4–3.5 M
⊙, radii of 1.5–4.7 R
⊙, and temperatures of 6400–10,300 K. We then compare the observed stellar parameters to the predictions of the stellar evolution models, but found that only one of our systems fits well with the evolutionary models.

Objective

Morbidity and mortality in rheumatoid arthritis (RA) is partly mitigated by maintaining immune and hematologic homeostasis. Identification of those at risk is challenging. Red cell distribution width (RDW) and absolute lymphocyte count (ALC) associate with cardiovascular disease (CVD) and mortality in the general population, and with disease activity in RA. How these variables relate to inflammation and mortality in RA was investigated.

Methods

In a retrospective single Veterans Affairs (VA) Rheumatology Clinic cohort of 327 patients with RA treated with methotrexate (MTX)+/− a tumor necrosis factor (TNF) inhibitor (TNFi), we evaluated RDW and ALC before and during therapy and in relation to subsequent mortality. Findings were validated in a national VA cohort (n = 13,914). In a subset of patients and controls, we evaluated inflammatory markers.

Results

In the local cohort, high RDW and low ALC prior to MTX treatment was associated with subsequent mortality over 10 years (bothP< 0.001). The highest mortality was observed in those with both high RDW and low ALC. This remained after adjusting for age and comorbidities and was validated in the national RA cohort. In the immunology cohort, soluble and cellular inflammatory markers were higher in patients with RA than in controls. ALC correlated with age, plasma TNF receptor II, natural killer HLA-DR mean fluorescence intensity, and CD4CM/CD8CM HLA-DR/CD38%, whereas RDW associated with age and ALC. MTX initiation was followed by an increase in RDW and a decrease in ALC. TNFi therapy added to MTX resulted in an increase in ALC.

Conclusion

RDW and ALC before disease-modifying antirheumatic drug therapy are associated with biomarkers of monocyte/macrophage inflammation and subsequent mortality. The mechanistic linkage between TNF signaling and lymphopenia found here warrants further investigation.
Evaluating the Threshold Score for Classification of Systemic Lupus Erythematosus Using the EULAR/ACR Criteria
Authors: Johnson Sindhu R. , Diaz Martinez Juan P. , Whittall-Garcia Laura , Urowitz Murray B. , Gladman Dafna D. , Touma Zahi
Published: November 2022

Objective

To evaluate whether a change in the European Alliance of Associations for Rheumatology (EULAR)/American College of Rheumatology (ACR) systemic lupus erythematosus (SLE) classification criteria threshold score affects accurate classification of SLE cases compared to disease-based control subjects. We evaluated a range of threshold scores to determine the score that maximizes the accurate classification of early SLE.

Methods

We conducted a cross-sectional study comparing SLE cases and control patients. A EULAR/ACR criteria score was calculated using baseline information. Sensitivity, specificity, positive likelihood ratios (+LRs), and negative likelihood ratios (−LRs) with 95% CIs were used to evaluate operating characteristics. Threshold scores of 6 to 12 were evaluated in subjects with early disease (ie, disease duration of ≤ 5 years). +LRs > 10 and −LRs < 0.1 provide evidence to rule in or rule out SLE.

Results

A total of 2764 patients were included: 1980 SLE cases who fulfilled either the ACR or Systemic Lupus International Collaborating Clinics criteria and 784 control subjects. The EULAR/ACR SLE criteria had a sensitivity of 98% (95% CI 97-98), a specificity of 99% (95% CI 98-100), a +LR of 95.5 (95% CI 48.0-190), and a −LR 0.03 (95% CI 0.02-0.03). The criteria operated well in those with early disease, in women, in men, and in White, Black, Chinese, and Filipino people. A score of 10 maximized the accurate classification of patients with early disease (+LR 174.4, 95% CI 43.8-694.6; −LR 0.03, 95% CI 0.02-0.04). An increase in the threshold score from 10 to 11 resulted in significant worsening in the −LR (threshold score 10: −LR 0.03, 95% CI 0.02-0.03 vs threshold score 11: −LR 0.05, 95% CI 0.04-0.06).

Conclusion

The EULAR/ACR SLE classification criteria threshold score of 10 performs well, particularly among those with early disease and across sexes and ethnicities.

Published: November 2022

Objective

The 2021 Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations provide an evidence-based guide for selecting therapy based on the individual's disease features. Beyond the disease features and associated conditions (eg, uveitis and inflammatory bowel disease), comorbidities play an important role in selecting therapy for an individual patient.

Methods

We performed a systematic literature review. We examined the available evidence to inform treatment selection based on the presence or absence of comorbidities in psoriatic arthritis (PsA).

Results

Common comorbidities in PsA that may affect treatment selection include presence of baseline cardiovascular disease (CVD) or high risk for CVD, obesity and metabolic syndrome, liver disease, mood disorders, including depression in particular, chronic infections, malignancies, osteoporosis, and fibromyalgia and/or central sensitization.

Conclusion

Comorbidities may influence both the effectiveness of a given therapy but also the potential for adverse events. It is important to assess for the presence of comorbidities prior to therapy selection.

Authors: Srinivasalu Hemalatha , Treemarcki Erin Brennan , Rumsey Dax G. , Weiss Pamela F. , Colbert Robert A.
Published: November 2022

Objective

To validate the Juvenile Spondyloarthritis Disease Activity Index (JSpADA), and modified versions thereof, in a North American cohort of patients with enthesitis-related arthritis (ERA).

Methods

We utilized the Childhood Arthritis and Rheumatology Research Alliance Registry database ERA cohort to validate the JSpADA and its modifications (JSpADA6-no Schober, no C-reactive protein [CRP]/erythrocyte sedimentation rate [ESR]; JSpADA7-no Schober; and JSpADA7-no CRP/ESR) using the Outcome Measures in Rheumatology principles of face validity, discriminative validity, and responsiveness to change.

Results

There were 51 subjects (64 visits) with complete JSpADA data with a mean age of 13.7 years and disease duration of 30.9 months. Subjects were predominantly White (84.3%), and 56.9% were male and 50% were HLA-B27 positive. The JSpADA showed high correlation with the clinical 10-joint Juvenile Arthritis Disease Activity Score (cJADAS10;r= 0.81), moderate-to-high correlation with physician global assessment (PGA;r= 0.69), and low-to-fair correlation with Childhood Health Assessment Questionnaire (CHAQ;r= 0.22). The modifications of the JSpADA (JSpADA7-no Schober; JSpADA7-no CRP/ESR; and JSpADA6-no Schober, no CRP/ESR) performed similarly with high correlation with cJADAS10 (r= 0.81, 0.79, and 0.80, respectively), moderate-to-high correlation with PGA (r= 0.65, 0.67, 0.64, respectively), and low-to-fair correlation with CHAQ (r= 0.35, 0.34, 0.39, respectively). All modified versions of JSpADA had good responsiveness to change. All versions of JSpADA had excellent discriminative validity.

Conclusion

We propose the termmodified JSpADAfor the modification of JSpADA with 6 elements (JSpADA6-no Schober, no CRP/ESR). This shorter disease activity index may improve implementation of JSpADA in both clinical practice and research trials.
Effects of Aging on Rheumatoid Factor and Anticyclic Citrullinated Peptide Antibody Positivity in Patients With Rheumatoid Arthritis
Authors: Takanashi Satoshi , Takeuchi Tsutomu , Kaneko Yuko
Published: November 2022

Objective

We investigated the factors that affect rheumatoid factor (RF) and anticyclic citrullinated peptide antibody (anti-CCP) positivity in patients with rheumatoid arthritis (RA).

Methods

The study included all consecutive patients with RA treated at Keio University Hospital between 2016 and 2017. We recorded age at diagnosis, sex, smoking habit, BMI (kg/m2), and family history, and investigated the association between these variables and RF and anti-CCP positivity.

Results

We recruited 1685 patients with RA. The mean age at diagnosis was 51.9 years, and 83.4% of the patients were women. Positivity rates of RF and anti-CCP almost linearly decreased along with the increase in age at RA diagnosis (grouped by decade) after ≥ 30 years of age (RF: 80.5%, 84.2%, 81.1%, 78%, 74.6%, 62.6%, 51.4%,P< 0.001; anti-CCP: 79.9%, 87.4%, 81.7%, 74%, 70.5%, 60.2%, 37.1%;P< 0.001). Multivariable analysis revealed that age was independently associated with seronegativity in women (RF: odds ratio [OR] 0.98, 95% CI 0.97-0.99,P< 0.001; anti-CCP: OR 0.97, 95% CI 0.96-0.98;P< 0.001), nonsmoking history (RF: OR 0.98, 95% CI 0.97-0.99,P< 0.001; anti-CCP: OR 0.97, 95% CI 0.96-0.98;P< 0.001), and BMI < 25 (RF: OR 0.98, 95% CI 0.97-0.99;P< 0.001; anti-CCP: OR 0.97, 95% CI 0.97-0.98;P< 0.001).

Conclusion

Aging is an independent contributor for seronegative RA in patients who are female, have a nonsmoking history, and a BMI < 25.

Psychometric Testing of the Preceptor Self-Assessment Tool (PSAT)-40 for Nursing Preceptors
Authors: L'Ecuyer Kristine , Subramaniam Divya S. , Reangsing Chuntana , DuBois John C.
Published: November 2022

Background

The aim of this study was to complete the third phase of development of the Preceptor Self-Assessment Tool (PSAT).

Method

Psychometric testing was conducted via an online Qualtrics survey with a statewide sample of 320 nurse preceptors from July to September 2020. Exploratory factor analysis and internal consistency and scale reliability testing were conducted on the 64-item PSAT.

Results

Exploratory factor analysis identified three factors: (1) inter/intrapersonal skills and attitudes, (2) knowledge and understanding, and (3) administrative resources and support. Cronbach's alpha values for the PSAT-40 ranged from 0.978 to 0.998. Final scale reliability was excellent at 0.983.

Conclusion

The Preceptor Self-Assessment Tool, now in its final form as the PSAT-40, has established construct validity and reliability and can be used to assess competency as a preceptor. Nurse educators can use this instrument to assess the needs of nurse preceptors and develop strategic nursing preceptor education programs.

Electronic Health Record Knowledge, Skills, and Attitudes Among Newly Graduated Nurses: A Scoping Review
Authors: Weinschreider Joanne , Sisk Heather , Jungquist Carla
Published: November 2022

Background

This scoping review aimed to identify key characteristics related to electronic health record (EHR) end-user system optimization levels among graduating/newly graduated nurses.

Method

Using a systematic approach to conducting a scoping review, 11 articles were identified from three databases. Articles were reviewed for nursing level status, type of EHR used for research, type of assessment, and which EHR knowledge, skills, or attitudes were studied.

Results

The majority of the studies used a reported by evaluator approach that examined the accuracy of EHR documentation (e.g., skills). EHR knowledge was examined in two studies. No study examined EHR attitudes. Studies that reflected self-reported data mainly focused on EHR skills related to navigating, finding, utilizing, and showing and EHR knowledge gains.

Conclusion

Graduating/newly graduated nurses have gaps in EHR skills, knowledge, and attitudes. Simulation and EHR education are viable pedagogical approaches to building EHR end-user system optimization.

Numerical analysis of some partial differential equations with fractal-fractional derivative
Authors: Alharthi Nadiyah Hussain , Atangana Abdon , Alkahtani Badr S.
Published: November 2022

In this study, we expanded the partial differential equation framework to which fractal-fractional differentiation can be applied. For this, we employed the generalized Mittag-Leffler function, and the fractal-fractional derivatives based on the power-law kernel. A general partial differential equation with the fractal-fractional derivative, the power law kernel and the generalized Mittag-Leffler function was thoroughly examined. There is almost no numerical scheme for solving partial differential equations with fractal-fractional derivatives, as less investigation has been done in this direction in the last decades. In this work, therefore, we shall attempt to provide a numerical method that might be used to solve these equations in each circumstance. The heat equation was taken into consideration for the application and numerically solved using a few simulations for various values of fractional and fractal orders. It is observed that, when the fractal order is 1, one obtains fractional partial differential equations which have been known to replicate nonlocal behaviors. Meanwhile, if the fractional order is 1, one obtains fractal-partial differential equations. Thus, when the fractional order and fractal dimension are different from zero, nonlocal processes with similar features are developed.
