Authors: NUGRAHA Budi , RUSADI Udi , JAMALULLAIL Jamalullail
Published: December 2022

The survival of print media in the internet and social media era is increasingly threatened, especially with the increase in paper prices and the shift of advertisers to online media. One common strategy that print newspapers adopt is to establish an online version of the print newspaper and, accordingly, become a hybrid newspaper. This paper explores how three hybrid local newspapers in Indonesia reacted to the challenges of digitalization in three different market structures: monopolistic, duopoly, and oligopoly. We see this as a form of media behavior in dealing with market structures formulated in the structure-conduct-performance (SCP) paradigm. The analysis attempts to find a typology of local hybrid newspapers based on the three interrelated components of SCP. The data of this study were obtained from interviews with top management of the three newspapers, accompanied by primary and secondary literature studies. The study found different practices of the three newspapers responding to their respective markets in terms of organizational structure, content, and support channels, online and offline. It allows us to formulate three types of mixed media: social hybrid media, business hybrid media, and Omni hybrid media. Strategy carried out by the business hybrid media allows gain profits and improve employee welfare
Acute Gastric Dilatation due to Pyloric Band, with Acute Appendicitis and IleoIleal Intussusception in a 4-Year-Old Girl: Case Report
Authors: WEDAWATI Ida Ayu Diah , MAHAYANA Putu Windhu , WISMAYA I Gede Putu Wegen , BHARATA Made Dwi Yoga
Published: December 2022

Acute gastric dilatation (AGD) is caused by mechanical and non-mechanical stomach processes. Acute appendicitis affects children and is treated with surgery. Intussusception is proximal bowel invagination against the distal bowel. Clinical findings of intussusception in the form of intermittent abdominal pain, a palpable mass in the abdomen, accompanied by wine-red stools. Due to significant morbidity and mortality, multiple-problem surgical emergencies require accurate diagnosis and treatment. A 4-year-old girl complained of a full stomach, abdominal discomfort, inability to flatus, vomiting, and fever, suggesting appendix perforation and widespread peritonitis. Radiographs show an intra-abdominal mass. Exploratory laparotomy surgery revealed gastric dilatation due to the pyloric band, acute appendicitis, ileoileal intussusception, grade 3 adhesions, and generalized peritonitis. Laparoscopic surgery revealed significant issues. The procedure was followed by partial gastrectomy, milking procedures, appendectomy, omentectomy and release of adhesions. Gastric histopathological examination showed the results of acute suppurative gastritis. Postoperatively the patient was hospitalized for nine days with improved condition. The complex pathogenesis is related to multiple cases in these patients. A continuous process is thought to occur between acute appendicitis and ER through the mechanism of intra-abdominal infection involving the omentum according to the anatomical location. Then hypertrophy of the lymphoid tissue of Peyer's plaque due to acute appendicitis is thought to contribute to intussusception. Clinical evaluation and appropriate management of surgical emergency cases with multiple problems are important to prevent further deterioration and complications.

Authors: NYAHUNA Thomas , DOORASAMY Mishelle
Published: December 2022

This paper examines the impact of carbon tax on financial sustainability of cement and mining companies in South Africa listed on the Johannesburg Stock Exchange. Quantitative research method was used. Correlation analysis was used to analyse the data. Secondary data in form of annual integrated reports, sustainability reports and annual audited financial statements from 2016 to 2020 were used as sources of the variables. The results show that carbon tax adversely influences net profit margin. Therefore, this suggests that carbon tax also negatively impacts shareholders’ dividends. Therefore, this suggests that carbon tax also negatively impacts shareholders’ dividends. This study is significant to policy makers by providing valuable information relating to the effect of carbon pricing decisions on the profitability of the cement and mining sector in South Africa. This gives the policy makers an evidence-based opportunity on designing and developing policies that take into consideration that carbon tax is reducing financial performance of the corporate sector in South Africa.  This study contributes to the contemporary literature on nexus between carbon tax and financial sustainability from developing country perspective. Furthermore, this is the first empirical study in South Africa focusing on this relationship.

Published: December 2022

Objective

Several advanced therapies have been licensed across the related conditions of psoriatic arthritis (PsA), Crohn disease (CD), ulcerative colitis (UC), and noninfectious uveitis. We sought to summarize results from randomized controlled trials (RCTs) investigating the efficacy and safety of advanced therapies for these related conditions in patients with PsA.

Methods

We updated the previous systematic search conducted in 2013 with literature reviews of MEDLINE, Embase, and the Cochrane Library (from February 2013 to August 2020) on this subject; only those new studies are presented here. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework.

Results

The number of RCTs meeting eligibility criteria were 12 for CD, 15 for UC, and 5 for uveitis. The tumor necrosis factor inhibitor (TNFi) class appears to be efficacious and safe across CD, UC, and uveitis, with the exception of etanercept. Interleukin 12/23 inhibitors (IL-12/23i) are efficacious for CD and UC. Phase II and III RCTs of Janus kinase inhibitors (JAKi) and IL-23i in CD and UC are promising in terms of efficacy and safety. IL-17i must be used with great caution in patients with PsA at high risk of inflammatory bowel disease (IBD). RCTs in uveitis have mainly studied adalimumab.

Conclusion

We have identified 32 recent RCTs in IBD and uveitis and updated recommendations for managing patients with PsA and these related conditions. A multispecialty approach is essential to effectively, safely, and holistically manage such patients. Advanced therapies are not equally efficacious across these related conditions, with dosing regimens and safety varying.
Stepping Forward: A Scoping Review of Physical Activity in Osteoarthritis
Authors: White Daniel K. , Jakiela Jason , Bye Tom , Aily Jessica , Voinier Dana
Published: December 2022

Physical activity (PA) is recommended to mitigate the symptoms of osteoarthritis (OA); however, this modality remains an unfamiliar construct for many patients and clinicians. Moreover, there can be confusion over the nuanced differences in terminology, such as exercise, sedentary behavior, and moderate intensity. The purpose of this scoping review is to provide a basic overview of PA including terminology, summarize the importance of PA for adults with OA, and discuss current gaps in the literature. Broadly, PA is defined as any energy expenditure from skeletal muscle above a resting level, and exercise is considered a type of PA that is planned, structured, and repetitive. Robust literature shows that PA has a modest protective effect on pain, functional limitation, and disability for OA, in addition to positive effects on a broad range of outcomes from mood and affect to mortality and morbidity in the general population. We provide recommendations for which measurement instruments can be used to record PA, both from a clinical and research perspective, as well as which metrics to employ for summarizing daily activity.
An adaptive offloading framework for license plate detection in collaborative edge and cloud computing
Authors: Zhang Hong , Wang Penghai , Zhang Shouhua , Wu Zihan
Published: December 2022

With the explosive growth of edge computing, huge amounts of data are being generated in billions of edge devices. It is really difficult to balance detection efficiency and detection accuracy at the same time for object detection on multiple edge devices. However, there are few studies to investigate and improve the collaboration between cloud computing and edge computing considering realistic challenges, such as limited computation capacities, network congestion and long latency. To tackle these challenges, we propose a new multi-model license plate detection hybrid methodology with the tradeoff between efficiency and accuracy to process the tasks of license plate detection at the edge nodes and the cloud server. We also design a new probability-based offloading initialization algorithm that not only obtains reasonable initial solutions but also facilitates the accuracy of license plate detection. In addition, we introduce an adaptive offloading framework by gravitational genetic searching algorithm (GGSA), which can comprehensively consider influential factors such as license plate detection time, queuing time, energy consumption, image quality, and accuracy. GGSA is helpful for Quality-of-Service (QoS) enhancement. Extensive experiments show that our proposed GGSA offloading framework exhibits good performance in collaborative edge and cloud computing of license plate detection compared with other methods. It demonstrate that when compared with traditional all tasks are executed on the cloud server (AC), the offloading effect of GGSA can be improved by 50.31%. Besides, the offloading framework has strong portability when making real-time offloading decisions.
Inequality and earnings dynamics in France: National policies and local consequences
Authors: Kramarz Francis , Nimier-David Elio , Delemotte Thomas
Published: December 2022

This paper provides new stylized facts about labor earnings inequality and dynamics in France for the period 1991–2016. Using linked employer–employee data, we show that (i) labor inequality in France is low compared to other developed countries and has been decreasing until the financial crisis of 2009 and increasing since then, (ii) women experienced high earnings growth, in particular at the bottom of the distribution, in contrast to the stability observed for men. Both result from a decrease in labor costs at the minimum wage and an increase in the hourly minimum in the aftermath of the 35h workweek policy, (iii) top earnings (top 5 and 1%) grew moderately while very top earnings (top 0.1 and 0.01%) experienced a much higher growth, (iv) inequality between and within cohorts follow the same U‐shaped pattern as global inequality: it decreased before 2009 and then increased until 2016, (v) Individual earnings mobility is stable between 1991 and 2016, and very low at the top of the distribution, (vi) the distribution of earnings growth is negatively skewed, leptokurtic, and varies with age. Then, studying earnings dispersion both within and between territories, we document strong differences across cities as well as between urban and rural areas, even after controlling for observable characteristics. We also observe a continuous decrease in earnings inequality between territories. However, a larger inflation in rural territories mitigates this convergence. Finally, we document a strong reduction in inequality within rural and remote territories, again driven by changes at the bottom of the wage distribution.
Intelligent Information Network Security Management Strategy for Service Innovation of Manufacturing Enterprises Under Blockchain
Authors: Zhang Zhe , Li Chengcheng
Published: December 2022

Since the beginning of the new century, all manufacturing enterprises have been seeking ways to transform and upgrade the systems to maintain their competitive advantages. In the process of transformation and upgrading, service innovation has become more vital. In the service innovation mode, customers and suppliers are mainly involved in the manufacture of products. In the process of communication, these suppliers and customers need to rely on public key infrastructure (PKI) for data encryption and identity authentication operations, thereby achieving reliable information exchange and identity authentication in an untrusted environment. Therefore, ensuring the security of network communication for various types of users is crucial. The purpose of this paper is to solve the problem that results when a tampered certificate is difficult to trace due to the single point of failure and vulnerability of the current settlement and authentication system. In this scenario, the user's identity information is leaked in the certificate application. Resolving this problem is necessary to ensure the security of the information network.
Improving Patient Safety by Increasing Staff Knowledge of Evidence-Based Pulse Oximetry Practices
Authors: Hlavin Danielle , Varty Maureen
Published: December 2022

Background

Pulse oximetry is commonly used in critical care settings to monitor oxygenation status and assist with decision-making regarding oxygen therapy. Although it is imperative that nurses follow manufacturer guidelines, off-label use is common and could affect patient safety.

Objective

To increase staff members’ knowledge and reduce the frequency of off-label pulse oximeter placement in the critical care setting.

Methods

A preintervention audit was completed to assess the frequency of off-label use, and a preintervention survey was given to staff. Health care staff in the critical care units received an educational intervention. A postintervention survey for health care staff and a postintervention audit were completed to assess outcomes. With the support of hospital management, 90 ear probes were purchased for critical care settings to address supply barriers to the use of appropriate pulse oximetry sensors.

Results

In the preintervention audit (508 observations), a finger probe was used off label on the ear in 77 patients (15.2%). In the postintervention audit (365 observations), a finger probe was used on the ear in only 3 patients (0.8%).

Conclusion

Providing a brief educational session and making ear pulse oximeter probes readily available in the critical care setting increased compliance with manufacturer guidelines and helped ensure safe pulse oximetry monitoring.
Arteriovenous aistula following total thyroidectomy treated with angioembolization
Authors: Caunter G. M.
Published: December 2022

The development of an arteriovenous fistula as a complication following a thyroidectomy is a rare phenomenon. We report a case of a 24 year old man who developed this unusual complication post operatively. The fistula was detected during a routine follow up 3 months after the surgery when he complained of a vibration in his neck. Diagnosis of an abnormal communication between the right superior thyroid artery and the internal jugular vein was demonstrated by performing a Computed Tomography Angiography (CTA). He was successfully treated with embolization and coiling of the aneurysm.

Convolution identities of poly-Cauchy numbers with level 2
Authors: Komatsu Takao
Published: December 2022

Poly-Cauchy numbers with level 2 are defined by inverse sine hyperbolic functions with the inverse relation from sine hyperbolic functions. In this paper, we introduce the Stirling numbers of the first kind with level 2 in order to establish some relations with poly- Cauchy numbers with level 2. Then, we show several convolution identities of poly-Cauchy numbers with level 2. In particular, that of three poly-Cauchy numbers with level 2 can be expressed as a simple form.

Rapidly Progressive Malignant Pelvic Perivascular Epithelioid Cell Neoplasm (PEComa) Associated with Eggerthella lenta Bloodstream Infection
Authors: Cacciatore Stefano , Recupero Carla , Massaro Claudia , Elmi Daniele , Fusco Domenico , Badiali Vanessa , Brandi Vincenzo , Arciuolo Damiano , Marazzi Fabio , Landi Francesco
Published: December 2022

Perivascular epithelioid cell tumors (PEComa) are rare mesenchymal neoplasms composed of cells that express melanocytic and myogenic markers and grow around small blood vessels. PEComa often show benign behaviors but can also be highly aggressive. In frail and more complex patients, many conditions can overlap, compounding the diagnostic and therapeutic difficulties inherent in rare diseases. Moreover, the complexity of modern patients introduces new and significant players in host-microbe interactions, and emerging pathogens represent a relevant challenge to modern healthcare. Among these pathogens is Eggerthella lenta, an anaerobic gram-positive bacterium of the normal gut microbiota associated with life-threatening infections. Here, we present a case of malignant pelvic PEComa with rapid metastatic progression in a 73-year-old man who presented with an E. lenta bloodstream infection. Approaching differential diagnosis with open-mindedness may assist in better imaging interpretation, surgery scheduling, and proper treatment planning. The non-specific clinical presentation might delay timely diagnosis, while the absence of well-consolidated guidelines undermines the accurate management of the disease, for which strict follow-up can favor better outcomes. Progress in diagnostic techniques, such as the implementation of MALDI-TOF (matrix-assisted laser desorption/ionization-time of flight) mass spectrometry for micro-organism identification, helps with a more accurate pathogen diagnosis and characterization. This allows the implementation of the most appropriate therapy, as well as better surveillance of antibiotic resistance, infection prevention, and control measures. Nevertheless, a good dose of wisdom is vital to avoid overlooking potentially harmful pathogens, particularly in frail individuals.

‘Freedom’ on the Road to Ruin: An Australian Apology to America’s Freedom-Loving Hard Right.
Authors: Duhs L
Published: December 2022

Contemporary America faces deep-seated problems - not least because so many Americans have lost respect for their own electoral system and democratic institutions. America suffers too from unrelenting right wing hyperbole in respect of significant social issues, including their conviction that only they understand, and value, freedom. Because of Australia’s restrictive responses to the covid-19 pandemic, Florida’s Governor Ron DeSantis – a potential Presidential candidate - denigrates Australia as ‘not a free country; not a free country at all’. Australians may dismiss Governor DeSantis’s comments as laughable, but a chorus of hard right comments in support of his view invites a comparison of the different ways in which ‘freedom’ is understood in Republican America and in Australia. One consequence of DeSantis’s conception of ‘freedom’ is the extraordinary American death rate from the Covid-19 pandemic, which in the case of Florida – which DeSantis celebrates as the ‘free-est State’ – stood at about 48 times the Australian rate when he scorned Australia as indistinguishable from communist China. Despite massive American spending on defence budgets, a domestic battle has been waged, and lost, in respect of the more prosaic defence of America’s traditional economic philosophy, and its defining institutions; and American conservatives are now divided even within their own ranks as to what it is that they wish to conserve, other than partisan advantage. The roots of America’s present malaise are to be found in the evolving (mis)understandings of a set of keywords including ‘freedom’, ‘democracy’, ‘tyranny’, ‘individualism’, and ‘society’. The radical right has impoverished the understanding of these keywords, and Australia’s pandemic response was in fact designed to give itself freedom from the ‘freedom’ that the Republican right now eulogises. In the name of an implicit and contentious teleological vision, the Republican understanding of ‘freedom’ has now descended to the point where America’s hard right perversely sees itself as actually now needing to save Australia from democracy, while simultaneously undermining its own democratic institutions. The need for a reinvigorated teaching of economic philosophy is plain to see.
Efficient Update of Redundancy Matrices for Truss and Frame Structures
Authors: Krake Tim , von Scheven Malte , Gade Jan , Abdelaal Moataz , Weiskopf Daniel , Bischoff Manfred
Published: December 2022

Redundancy matrices provide insights into the load carrying behavior of
statically indeterminate structures. This information can be employed for the
design and analysis of structures with regard to certain objectives, for
example reliability, robustness, or adaptability. In this context, the
structure is often iteratively examined with the help of slight adjustments.
However, this procedure generally requires a high computational effort for the
recalculation of the redundancy matrix due to the necessity of costly matrix
operations. This paper addresses this problem by providing generic algebraic
formulations for efficiently updating the redundancy matrix (and related
matrices). The formulations include various modifications like adding,
removing, and exchanging elements and are applicable to truss and frame
structures. With several examples, we demonstrate the interaction between the
formulas and their mechanical interpretation. Finally, a performance test for a
scaleable structure is presented.
Фізико-хімічні властивості флюсів та їхні технологічні параметри
Authors: Рибалко Іван , Сайчук Олександр , Захаров Андрій
Published: December 2022

Узагальнено експериментальні та літературні дані щодо властивостей та функцій флюсів та шлаків, що застосовуються для ведення стійких процесів наплавки в різних електрошлакових технологіях. Запропоновано формулу розрахунку тепла, що виділяється при електрошлаковій наплавці (ЕШН). Досліджено щільність та наведено температури плавлення різних флюсів. Проблема отримання якісного металу, з заданими фізико-механічними властивостями та службовими характеристиками, є однією із головних завдань у сучасному світовому металургійному виробництві, від якої безпосередньо залежить прогрес у багатьох галузях промисловості. Існує ряд технологічних процесів отримання якісного металу – вакуумно-індукційний переплав, вакуумно-дуговий переплав, електронно-променевий переплав, що мають свої переваги та недоліки та певні технічні обмеження. Вони не вирішують проблему загалом. Споживання флюсів (шлаків) на основі CaF2, Al2O3, MgO, CaO, MnO, SiO, NaF і т. д. у металургійному виробництві швидко зростає. Це зумовлено створенням та впровадженням у виробництво нових методів виплавки якісних сталей та сплавів, до яких пред'являють особливі вимоги фізико-хімічних властивостей металургійних флюсів. Є кілька загальних функцій, які шлак виконує в електрошлакових процесах. Це насамперед енергоперетворююча функція. Шлак є ділянкою електричного ланцюга з високим опором, на якому відбувається перетворення електричної енергії на теплову. Крім того, він виконує теплопередавальну функцію, від якої залежить енергетична ефективність процесу. Ця ефективність тим вища, чим повніше та інтенсивніше шлак передає теплоту металу. Шлак є невід'ємною складовою кожного процесу (ЕШН) електрошлакових технологій, наплавлення, лиття тощо. Ефективність, продуктивність процесів залежить від його властивостей, що визначають, головним чином, хімічним складом компонентів флюсів, що застосовуються.

Published: December 2022

Well logs data was analyzed and used to identify reservoir properties. The Mishrif Formation was sudivided into six units (MA, MB1, MB2, MC1, MC2 and MC3) with different potential characteristics. By using the MID method and M-N cross plots to determine the rock and mineral composition of the Mishrif Formation in the X oil field, it was found through the profiles that the Mishrif Formation consists largely of limestone, little dolomite and shale. Based on the CPI results of the two wells (XA and XB)it was noted that the units BM1, BM2 and MC1 reservoir units have good petrophysical properties as they had good porosity ranging from 0.1 to 0.19 with low values of water saturation (0.3-0.79) and shale volume (0.0295-0.070) respectively). Due to these characteristics these units are considered oil-bearing areas are among the most important units in the Mishrif Formation in the X field. while the other units (MA, MC2 and MC3) are considered non-reservoir units due to It has poor petrophysical properties.

Published: December 2022

Background: Limited information is available on anesthetics that are preferred or used by anesthesiologists for cesarean section (CS) delivery in Kurdistan region, Iraq. This study aims to document general or regional anesthesia use in elective CS deliveries in four major hospitals in Duhok province, Northern Iraq. 
Methods: A retrospective cross-sectional study was conducted from February 2019 to February 2020. The general and regional anesthetics types were recorded for each CS delivery case within the selected hospitals. Any adjuvants and medications used with the anesthetics were also recorded. Univariate and bivariate analyses were undertaken. The statistically significant was considered at less than 0.05.
Results: A total of 3420 elective CS deliveries were reported. The mean age ± SD of the pregnant women was 29.6 ± 5.8 years. The anesthetics used in the four hospitals were propofol as a general anesthetic (53.0%) and bupivacaine as a spinal anesthetic (47.0%). The combination of propofol and bupivacaine was used only in 0.3%. The three most frequently and concurrently used adjuvants and medications with propofol or bupivacaine were metoclopramide (90.0%), dexamethasone (80.0%), and ephedrine (73.0%).
Conclusion: Propofol and bupivacaine were the general and spinal anesthesia of choice, respectively, for elective CS delivery in Duhok province, northern Iraq. Some adjuvants and medications were supplemented to improve the quality of anesthesia and the outcome of CS delivery.
