Authors: Haddad Jorge Selem , Gouvea Larissa , Ambrósio Renato , Waring George O. , Rocha Karolinne M.
Published: October 2022

PURPOSE:

To compare objective measurements of accommodation and pseudoaccommodation in phakic and pseudo-phakic eyes using ray-tracing aberrometry.

METHODS:

Patients with normal and hyperprolate corneas (post-hyperopic laser in situ keratomileusis) who underwent cataract surgery from March 2018 to October 2019 at the Medical University of South Carolina were examined and received either a diffractive intraocular lens (IOL) with an echelette design (Tecnis ZXR00 Symfony; Johnson & Johnson Vision), a monofocal IOL with negative spherical aberration (Tecnis ZCB00; Johnson & Johnson Vision), or an aberration-free IOL (MX60E; Bausch & Lomb). The control groups consisted of young and presbyopic phakic patients. Ray-tracing wavefront analysis was performed 1 to 3 months postoperatively. Objective ray-tracing metrics of accommodation and pseudoaccommodation included the effective range of focus, sphere shift accommodation, and depth of focus.

RESULTS:

Sixty-two eyes received a Tecnis ZCB00, 39 a MX60E, and 43 a Tecnic ZXR00 Symfony IOL; furthermore, 20 young phakic eyes and 19 presbyopic eyes were included in this study. The effective range of focus and sphere shift accommodation in the young control group were statistically larger than in the presbyopic group (
P
= .005 and
P
< .001, respectively). There was no difference in effective range of focus, sphere shift accommodation, and pseudoaccommodations between the different IOL groups. The young control group had the highest visual Strehl optical transfer function for near and distant targets (0.64 ± 0.24 and 0.56 ± 0.19, respectively), whereas the aberration-free IOL in the MX60E hyperprolate cornea group presented the lowest visual Strehl optical transfer function value for near (0.49 ± 0.19).

CONCLUSIONS:

Ray-tracing aberrometry can objectively assess accommodative amplitude in phakic eyes and pseudoaccommodation (depth of focus) in pseudophakic eyes.

Authors: Aribas Yavuz Kemal , Tefon Aribas Atike Burcin , Ercin Ugur , Sarıkaya Burcu , Bilgihan Ayşe , Bilgihan Kamil
Published: October 2022

PURPOSE:

To evaluate the biomechanical changes and advanced oxidation protein products (AOPP) production after different corneal cross-linking (CXL) protocols with or without oxygen supplementation.

METHODS:

Ovine eyes in the study were equally distributed to five groups as control, standard Dresden protocol, diluted alcohol- and iontophoresis-assisted CXL (DAI-CXL), and 0.1% and 0.2% riboflavin-mediated iontophoresis-assisted CXL with oxygen supplementation (I-CXL). Corneas that received CXL were divided into two equal parts, one part was used for uniaxial tensiometry and one part was used for AOPP measurement.

RESULTS:

All treatment groups showed higher Young's modulus and stiffness compared to the control group (
P
< .05). Both oxygen-assisted I-CXL groups with 0.1% and 0.2% riboflavin concentrations had higher corneal Young's modulus (
P
= .009 and .006, respectively) and stiffness (
P
= .009) values, whereas the DAI-CXL group had lesser Young's modulus and stiffness values (
P
= .032) compared to the Dresden protocol group. All treatment groups showed higher AOPP concentrations compared to the control group (
P
< .05). DAI-CXL and I-CXL groups showed similar AOPP formation compared to the Dresden protocol (
P
= .673).

CONCLUSIONS:

When the epithelium is intact, the desired increase in corneal stiffness might not be achieved. However, increasing the oxygen in the environment might provide a sufficient increase in stiffness in cases undergoing epitheliumon I-CXL, which might be promising in terms of shortening the CXL therapy and decreasing the complications.

Nursing Staff Perceptions of Outcomes Related to Honoring Residents' “Risky” Preferences
Authors: Behrens Liza L. , Boltz Marie , Sciegaj Mark , Kolanowski Ann , Jones Joanne Roman , Paudel Anju , Van Haitsma Kimberly
Published: October 2022

Nursing homes (NHs) are challenged to consistently deliver person-centered care (PCC), or care based on residents' values and preferences. NH staff associate certain resident preferences with risk. However, there are limited evidence-based person-centered risk management strategies to assist NH staff with risky resident preferences. The purpose of the current study was to explore NH staff perceptions of health and safety outcomes associated with honoring NH residents' risky preferences to inform intervention development. This descriptive, qualitative study used sequential focus groups and content analysis, revealing that nursing staff perceive negative and positive outcomes for staff and residents when seeking to honor residents' risky preferences. This finding is supported by three themes:
Potential Harms to Staff
,
Potential Harms to Residents
, and
Positive Shared Outcomes
. These results contribute a set of nurse-driven quality of life and quality of care outcomes for NH staff and residents associated with PCC delivery in NHs. [

Authors: Madrigal Caroline , Resnick Barbara , Eshraghi Karen , Ellis Jeanette , Kolanowski Ann , Van Haitsma Kimberly
Published: October 2022

The Checklist for Evidence of Person-Centered Care Approaches for Behavioral and Psychological Symptoms of Distress (BPSD) in Care Plans was developed to assess the person-centeredness of care plans for nursing home residents living with behavioral and psychological symptoms associated with dementia. The purpose of the current study was to evaluate the reliability and validity of a revised version of the Checklist. Data from a larger randomized clinical trial testing the implementation of the Evidence of Integration Triangle for BPSD were used. One hundred seventy-nine care plans for 103 residents were examined. Descriptive statistics, Rasch analysis, and inter-rater reliability were used. The Checklist demonstrated evidence of inter-rater reliability and validity based on model fit and acceptable INFIT and OUTFIT statistics. This study serves as pilot work for future Checklist use and validation efforts on a larger scale. Findings encourage a discourse on the inclusion of BPSD and person-centered approaches in care plans for those living with dementia. [

A new multi-objective optimization ratio analysis plus full multiplication form method for the selection of an appropriate mining method based on 2-tuple spherical fuzzy linguistic sets
Authors: Khan Ayesha , Akram Muhammad , Ahmad Uzma , Al-Shamiri Mohammed M. Ali
Published: October 2022

The selection of an appropriate mining method is considered as an important tool in the mining design process. The adoption of a mining method can be regarded as a complex multi-attribute group decision-making (MAGDM) problem as it may contain uncertainty and vagueness. The main goal of this paper is to propose an extended multi-objective optimization ratio analysis plus full multiplication form (MULTIMOORA) method that is based on a 2-tuple spherical fuzzy linguistic set (2TSFLS). The MULTIMOORA method under 2TSFL conditinos has been developled as a novel approach to deal with uncertainty in decision-making problems. The proposed work shows that 2TSFLSs contain collaborated features of spherical fuzzy sets (SFSs) and 2-tuple linguistic term sets (2TLTSs) and, hence, can be considered as a rapid and efficient tool to represent the experts' judgments. Thus, the broader structure of SFSs, the ability of 2TLTSs to represent linguistic assessments, and the efficiency of the MULTIMOORA approach have motivated us to present this work. To attain our desired results, we built a normalized Hamming distance measure and score function for 2TSFLSs. We demonstrate the applicability and realism of the proposed method with the help of a numerical example, that is, the selection of a suitable mining method for the Kaiyang phosphate mine. Then, the results of the proposed work are compared with the results of existing methods to better reflect the strength and effectiveness of the proposed work. Finally, we conclude that the proposed MULTIMOORA method within a 2TSFLS framework is quite efficient and comprehensive to deal with the arising MAGDM problems.
REQUIREMENTS, INNOVATION AND PROCUREMENT: A 21st CENTURY UK PERSPECTIVE
Authors: Louth J
Published: October 2022

This paper explores the interactions between future defence requirements in a period of strategic uncertainty, the development of exquisite, technology-rich capabilities emerging from the private sector, and the potential changing face of government defence acquisition. It starts from the premise that the UK government’s practices in relation to defence and security procurement, sometimes taking years in managerial assessments, are unwieldy and unfit for rapid technology insertion and the demands of the modern epoch. This inhibits, specifically, the ability of innovative design and emerging technologies to be deployed on the front line, potentially eroding UK defence capabilities. The manner in which this systemic, governmental inhibition is being challenged by niche companies in the private sector is explored by way of a review of the development of Subsea Craft Ltd, a small, UK business in its infancy. Taking an ethnographic approach, the
work blends practices of horizon scanning, defence innovation and the commercialisation of ideas into the possibility of deployable defence capabilities.
JOINT RESEARCH PROJECT AUTOPLAN
Authors: Erol N
Published: October 2022

The paper introduces the joint research project AutoPlan, which was started by UZMAR, OES, FRIENDSHIP SYSTEMS, Technical University Berlin (TUB) and SVA Potsdam, under the MarTera (Horizon 2020) program. The goal of this project is the improvement of the safety and efficiency of planing crafts, by developing an Intelligent Navigation Assistance (INA) System. In the scope of the project, a new prototype vessel is going to be developed and built, based on an initial design provided by UZMAR (Turkey). This design will be parametrically modelled by FRIENDSHIP SYSTEMS (Germany) in order to optimize the efficiency, providing a state-of-the-art fuel saving design. The required simulation tools will be provided by the Technical University Berlin (Germany), which will also carry out a validation of the optimization results with model tests. In addition, TUB will develop a method to reliably predict the manoeuvring and instability behaviour of the planing crafts. The method will require virtual captive model tests, carried out with a RANS code, especially enhanced for this purpose. Based on these tests, a mathematical model will be developed, which takes into account all six degrees of freedom, allowing not only the prediction of rudder manoeuvres at planing condition, but also the assessment of certain types of instabilities.The method will also be experimentally validated with numerous model tests, which requires a novel experimental technique, that will be developed and installed at TUB. These mathematical models are then used by OES (Turkey), who will develop the INA system, which will support the decision making in navigation in order to avoid dynamic instabilities, like for example transversal instability or porpoising. At the end of the
project, UZMAR will build a full scale prototype with an integrated INA system to prove the capabilities in practice. The full scale measurements will be carried out by SVA Potsdam (Germany) and TUB and include the measurement of all ship motions as well as the thrust. The project and first results of modelling and simulation will be presented.

Authors: Zeid M
Published: October 2022

Greening and hybrid propulsion are being more and more common on the market. Apparently, looking to propulsion machinery arrangement and recognizing electric motor and batteries reflects a green propulsion system for the first while. However, being green it doesn’t mean only the electric motor and batteries. The greening is mainly about energy
utilization and optimization in sequence layers. This means greening concept as a start layer(s) has a direct connection to what is power configuration on board and what propulsion system available and how to utilize the available power to the specified propulsion. As a next layer(s), the optimization can be enhanced by utilizing digitalization possibilities to adopt system dynamically for the most optimum hybrid condition. The paper is going through this process where explaining optimization differences between different propulsion systems for being more and more green.

Authors: Thies F , Ringsberg J W
Published: October 2022

Wind-assisted propulsion is seen as one of the main alternatives to potentially achieve large emission reductions in shipping. However, wind-assisted propulsion introduces new challenges in the design, retrofitting and performance prediction as well as the performance analysis. This paper presents and compares methods to predict the performance of wind-assisted propulsion, using the validated performance prediction model ShipCLEAN. Focus is put on evaluating the difference between 1 degree of freedom (1 DOF) and 4 DOF methods as well as the impact of aerodynamic interaction effects in between multiple sails. Practical design considerations and performance differences are discussed based on an example ship. The study includes a comparison of the performance of different sail types (Flettner rotors, Wing sails and Suction wings) under realistic operational conditions.

Authors: Kuuskoski J
Published: October 2022

Norsepower’s Rotor Sails have been installed on a variety of ship types since 2014. This paper describes the technical and operational requirements for Rotor Sail installations on tankers, ro-ro-vessels, ferries and bulkers. Third-party verified performance results are presented as well as customer feedback on how the Rotor Sails are viewed by the ship’s crew. Operational requirements such as air draft restrictions and cargo operations can be complied with by applying a tilting Rotor Sail. Aspects related to tilting Rotor Sails and the first experiences from installations are described. The global shipping community faces enormous challenges in finding feasible and proven solutions to reduce their environmental impact and specifically fossil fuel related emissions. This paper discusses wind propulsion technology’s potential to be a significant part of the emission reduction solution in today’s ship designs.
INTERACTIONS BETWEEN TWO FLETTNER ROTORS USED FOR WIND SHIP ASSISTED PROPULSION
Authors: Charrier B
Published: October 2022

Wind tunnel tests are carried out at the Aerodynamics Laboratory of the Ecole Nationale des Arts et Métiers (ENSAM) in Paris on 50 mm and 130 mm diameter rotating circular cylinder in infinite aspect ratio or finite aspect ratio of 3 to 6, with or without rotating endplates. Aerodynamic forces are measured by a 5-components balance and by integrating pressures over three sections along the span of the rotating cylinder.
The tests carried out at Reynolds numbers between 13,500 and 70,000 are significant and make it possible to dispense tests at high flow speeds.
The results, based on pressure measurements, indicate that the rotation of the cylinder drives the fluid in a spiral motion along the span, winding the flow, accompanied by a very strong increase in the drag coefficient between the middle and the top of the cylinder.
The interaction between two rotating cylinders, spaced out by 6 diameters, decreases the ratio CL / CD of the thruster reducing its propulsive performance at close wind angles (30° <β <70°).

Authors: Garnett Gabriella , Venter Johanna M. , Geldenhuys Diederik J.
Published: October 2022

Orientation: Traditional models of planned change are no longer sufficient, amidst constantly changing contexts. Applied neurosciences provides a unique, integrated perspective on human functioning. This study employed a neuroscientific perspective to explore participants’ experiences of the neurobiological impact of emergent change.Research purpose: This study explored participants’ experiences of emergent change from an applied neurosciences perspective.Motivation for the study: The impact of emergent change on employees has been underestimated and under-represented in both the literature and practice. Exploring the original voices of employees, as well as the underlying neural mechanisms and their dynamic interactions that shape these experiences, offers new insights into this complex phenomenon.Research approach/design and method: Nine client-facing employees from a software development company in South Africa, selected through purposive sampling, participated in an interactive qualitative analysis (IQA) focus group and follow-up interviews. Data were collected and analysed by the participants, in keeping with the IQA protocol.Main findings: Experiences of emergent change were found to threaten individuals’ and teams’ basic psychological needs, with a significant impact on the physiological, emotional and interpersonal levels. The participants’ experiences reflected a dysregulation in mental operating network activation, in response to their compromised needs.Implications for practice: The findings imply the need for interventions to enhance employees’ resilience during emergent change by developing the internal stability and external adaptability of their mental operating networks. This aligns with developments related to well-being in the neuroscience literature.Contribution/value add: The study provides an insight into individuals’ and teams’ experiences of emergent change, which can be used to inform new approaches for research-informed interventions and practices aligned with applied neurosciences.
Verskillende benaderings tot opleiding in bestuurskole en besondere behoeftes in Suid-Afrika

Business schools in South Africa are exposed to many often conflicting demands which create particular challenges for excellence and adaptation. The local schools are constantly compared with the very best in the world as executives frequently attend top business schools overseas or attend seminars by visiting overseas business teachers. Participants on business school programs demand up to date high quality teaching. As departments of universities they are in addition subjected to the normal university traditions. Overseas models of business schools include the functional approach adopted by most large universities overseas, the diagnostic case study approach and underlying discipline approach. A variety of other models combining elements of the basic approach also exist. It is important for South African business schools to investigate various approaches to business school education and devise own approaches appropriate to their particular needs. Regular exchange of faculty members with overseas business schools is essential for many reasons as is actively pursued by most local business schools. The remaining need which is the essential final step to maturity is active research in business, management and organization with development concepts, theory and application. This is a rapidly growing activity at South African business schools and must be strongly encouraged.

Die huidige vlak van besoldiging in die openbare sektor en die nadelige gevolge daarvan
Authors: Marias George
Published: October 2022

In this article the author looks critically at the level of remuneration in the public sector and its detrimental effects. He concludes that the main reason for the imbalance with regard to the external market rate for public servants should not necessarily be attributed to the policy of the Public Service Commission; the main reasons are, rather, of a structural nature, viz. creeping socialism in modern government, and the normalization of the labour pattern of the Afrikaans speaking section of the South African population. This structural imbalance is increased by chronic inflation. These factors, together with the ceiling placed on top salaries of public servants by politicians and political appointments, plus rapid salary increases for new employees, limited the real scope of the salary scales of public servants. These, in turn, contributed to the high labour turnover. The author poses the question whether the time has not arrived for the function of the public service to be curtailed.

Published: October 2022

Cardiopulmonary bypass (CPB) depletes endogenous Vitamin C and generates oxidative stress in cardiac surgery. This study aimed to clarify whether Vitamin C supplementation reduces oxidant production and improves erythrocyte deformability in cardiac surgery with CPB. In a randomized and controlled design, 30 eligible patients undergoing cardiac surgery with hypothermic CPB were equally assigned to the Vitamin C group and control group. Subjects of the Vitamin C group and control group received an intravenous infusion of Vitamin C 20 mg·kg–1 and a placebo during rewarming period of CPB, respectively. We measured the plasma level of reactive oxygen species (ROS) and phosphorylation levels of non-muscle myosin IIA (NMIIA) in erythrocyte membrane, as an index of erythrocyte deformability, before and after CPB. Vitamin C supplementation attenuated the surge in plasma ROS after CPB, mean 1.661 ± standard deviation 0.801 folds in the Vitamin C group and 2.743 ± 1.802 in the control group. The tyrosine phosphorylation level of NMIIA after CPB was upregulated in the Vitamin C group compared to the control group, 2.159 ± 0.887 folds and 1.384 ± 0.445 (P = 0.0237). In addition, the phosphorylation of vasodilator-stimulated phosphoprotein (VASP) and focal adhesion kinase (FAK) in erythrocytes was concurrently enhanced in the Vitamin C group after CPB. The phosphorylation level of endothelial nitric oxide synthase in erythrocytes was significantly increased in the Vitamin C group (1.734 ± 0.371 folds) compared to control group (1.102 ± 0.249; P = 0.0061). Patients receiving Vitamin C had lower intraoperative blood loss and higher systemic vascular resistance after CPB compared to controls. Vitamin C supplementation attenuates oxidative stress and improves erythrocyte deformability via VASP/FAK signaling pathway in erythrocytes during CPB.
Fetal hemoglobin as a predictor in cases of pre-eclampsia
Authors: Elrefaei Ahmed M.A. , Zakarya Abdel M.M. , Abdel Motaal Ahmed O. , Assem Ahmed A.
Published: October 2022

Background and Aim

Fetal hemoglobin (Hb) has been described as a new predictive biomarker for pre-eclampsia and has also been hypothesized to be a causative factor. Interestingly, the heme scavenger and antioxidant α-microglobulin increases in parallel with fetal Hb.

The aim was to measure the level of fetal Hb in the serum of pregnant women with pre-eclampsia.

Patients and methods

This a prospective study that was conducted on 100 pregnant women selected from the Obstetrics and Gynecology Department of Al-Hussein University Hospital.

Results

There was a significant increase in fetal Hb in the patient group more than the control group. The fetal Hb shows a high sensitivity, specificity, and accuracy in prediction of pre-eclampsia and eclampsia.

Conclusion

Fetal Hb was significantly higher in patients with eclampisa and pre-eclampsia. Moreover, it can be used as a predictive marker for both eclampisa and pre-eclampsia.
Laparoscopic versus open appendectomy in patients with acute appendicitis
Authors: Kamel Mohamed A. , Abdelfattah Mohamed , Shimy Gamal G.
Published: October 2022

Background and aim

There were numerous previous studies comparing open appendectomy (OA) with laparoscopic appendectomy (LA). Although most of these have concluded that the LA is good as OA, there has been considerable controversy as to whether LA is superior to OA or not.

The goal of this study was to compare the results of the previous two surgical methods and determine if LA is better than OA.

Patients and methods

A prospective research, including 40 patients with a suspected acute appendicitis, was conducted between January 2018 and May 2019. The LA group had 20 patients, while the OA group had 20 cases. LA was performed using three trocars/cannulas to create pneumoperitoneum with CO2, whereas OA was done using the Mc Burney incision (Clinical trial registration number : PACTR202203884835048).

Results

Appendectomies were done on 14 males and 26 women for a total of 40 appendectomies. In LA, the mean operative time was 45.50±13.26 min, whereas in OA, it was 53.50±14.78 min (P=0.001). In the LA group, none of the patients experienced intraoperative problems, but four individuals in the OA group did. Postoperative problems were observed in four (20%) patients in the LA group and five (25%) patients in the OA group. Compared with those who had OA, those who had LA had a considerably shorter hospital stay (14.60±5.45 vs. 24.10±5.60 h, P=0.001).

Conclusions

LA is just as safe and successful as OA, with key advantages such as less discomfort, fewer wound infections, and shorter hospital stays.
Short-term effects of prophylactic intravitreal injection of triamcinolone and moxifloxacin combination after cataract surgery
Authors: Saliem Emad A.A.
Published: October 2022

Background and Aim

To evaluate the short-term effects and safety of prophylactic intravitreal injection of triamcinolone–moxifloxacin combination after cataract surgery.

Patients and methods

This study included 100 eyes of 84 patients who underwent cataract surgery associated with intravitreal injection of triamcinolone–moxifloxacin combination after surgery. The patients were re-assessed at the first day, first week, and then monthly up to 3 months after surgery. The outcome measures included unplanned use of topical anti-inflammatory or anti-infective drugs during the postoperative period, best-corrected visual acuity (BCVA), and intraocular pressure (IOP). The mean age of patients was 55.99±5.20 years.

Results

The mean BCVA showed a statistically significant difference between the preoperative and the postoperative values, where the mean BCVA improved from 1.21±0.27 logMAR before operation to 0. 83±0.25 logMAR at the first week, 0.46±0.21 logMAR at the first month, and 0.19±0.14 logMAR at the third month. The mean IOP revealed no statistically significant differences between preoperative and postoperative values at the end of the first month (P<0.084). The preoperative IOP ranged from 12 to 19 mmHg, with an average of 15.35±1.60 mmHg and became 14.52±1.11 mmHg at the end of the first month after surgery. There was no evidence of postoperative complications such as endophthalmitis or other complications such as retinal detachment and vitreous hemorrhage.

Conclusion

Intravitreal injection of triamcinolone–moxifloxacin combination after cataract surgery can be used as an alternative to medications applied topically for prophylaxis against postoperative complications associated with cataract surgery such as infection and inflammation.
A study of the association between polymorphisms in the genes for interleukins IL-6 and IL-10 and negative symptoms subdomains in schizophrenia
Authors: Golimbet Vera , Lezheiko Tatyana , Mikhailova Vera , Korovaitseva Galina , Kolesina Nadezhda , Plakunova Victoria , Kostyuk Georgy
Published: October 2022

Background:

Schizophrenia is a severe mental illness manifested by various symptoms. Negative symptoms (NS) are associated with disability and poor function of patients. The study of NS neurobiology is complicated by their heterogeneity. Factor analysis revealed two distinct NS subdomains with different pathophysiological mechanisms: volitional pathology, including avolition and apathy (AA), and diminished expression (DE). Inflammation is one mechanism that may underlie NS, including their heterogeneity.

Aims:

To search for the association between genes for interleukins (IL-6 -174 G/C, IL-10 -592 C/A, and IL-10 -1082 G/A) and NS subdomains.

Materials and Methods:

The study included 275 patients with schizophrenia. NS factors were calculated based on the Positive and Negative Syndromes Scale.

Results:

There was a significant main effect of IL-10 polymorphisms on the AA, but not the DE subdomain. Mean score on the AA subdomain was higher in the IL-10 -592 AA compared to the CC genotype. Differences between IL-10 -1082 G/A genotypes were dose dependent. The lowest score was observed for the IL-10 -1082 GG genotype. The association between the IL-6 -174 G/C polymorphism and AA scores was close to the level of significance. Patients with the IL-6 -174 GG genotype had higher score compared to the AA genotype.

Conclusion:

The results provide further neurobiological evidence for the validity of the NS factor categorization. An imbalance between pro-inflammatory and anti-inflammatory cytokines because of genetic variations is associated with the AA NS subdomain that is supposed to be a more severe aspect of psychopathology compared to the DE.

Published: October 2022

Patients with post-acute sequelae after coronavirus disease (COVID-19) report a variety of non-specific neurological complications (e.g., myoclonus, limb weakness). In particular, they manifest scenarios as medically unexplained symptoms and are known as functional movement disorders (FMDs). We present three cases of FMDs in patients of the Institute of Clinical Medicine named after N. V. Sklifosovsky (Sechenov University). All patients had a history of COVID-19 infection and reported fatigue, weakness, and jerks of upper and lower limbs. In conclusion, there might be a major possibility of the virus negatively affecting the central nervous system, including such rare neuropsychiatric complications.

We investigate the leading digit distribution of thekth largest prime factor ofn(for each fixed$k=1,2,3,\dots $) as well as the sum of all prime factors ofn. In each case, we find that the leading digits are distributed according to Benford’s law. Moreover, Benford behavior emerges simultaneously with equidistribution in arithmetic progressions uniformly to small moduli.

Three-Dimensional Numerical Study of the inlet Temperature Effects on the Performance of Planar PEMFCs
Authors: Mohammedi Abdallah , Sahli Youcef , Ben Moussa Hocine
Published: October 2022

In the present study, a CFD (computational fluid dynamics) three-dimensional model is performed to investigate the effects of the inlet temperature on the power density, pressure and local transport phenomena of a single cell PEMFC (proton exchange membrane fuel cell) with straight channels. Deferent inlet temperatures of the reactants (333, 343 and 353 K) have been investigated using ANSYS-FLUENT. The interest of our work is focused on obtaining I-P and I-V curves as well as the pressure, hydrogen, oxygen and water mass fraction profiles to analyze the effect of the oxygen and hydrogen inlet temperature on the current, voltage and power densities of the studied PEMFC. From the results obtained its appears that the variation in the inlet temperature values of the PEMFC has a significant influence on the cell performances at medium and higher current density. Therefore, the results analysis of the three-dimensional and single-phase model indicates that the increase in the reactants’ inlet temperature of the studied PEMFC shows a negative impact on the generated power densities, which have an inversely proportional effect.

vulneración de derechos de la personas mayores durante la pandemia
Authors: Herreros López Juan Manuel
Published: October 2022

Durante las semanas más críticas de la emergencia sanitaria provocada por la pandemia de COVID-19, y especialmente en las residencias de mayores, se recomendó relegar a las personas de edad avanzada a la hora de ser derivadas a hospitales y ucis. Estas recomendaciones y su aplicación efectiva en muchos casos bien pudieron constituir una vulneración del principio de igualdad (art. 14 CE), el derecho a la salud (art. 43 CE) y el derecho a la vida (art. 15 CE) de las personas mayores afectadas. En las residencias se padeció asimismo un aislamiento particularmente rígido y duro, que además de poder lesivo del derecho a la libertad (art. 19 CE), tuvo consecuencias tan dolorosas como la muerte en soledad de muchas personas. La pandemia también ha incrementado el edadismo y la consiguiente estigmatización de los mayores, pues durante este tiempo se ha enfatizado, de forma injustificada y exagerada muchas veces, la asociación entre edad avanzada, covid y vulnerabilidad.
Jurisdicción social y siniestralidad laboral: los órganos jurisdiccionales sociales en cien años de historia
Authors: Macías García María del Carmen , Urbano Medina Andrés
Published: October 2022

La protección jurídica de la siniestralidad laboral supone, desde la aprobación de la Ley de Accidentes de Trabajo de 1900, la causa del desarrollo de, por un lado, el Derecho del Trabajo y de la Seguridad Social en España tal como lo conocemos y, por otro, del orden social de la jurisdicción. En el presente estudio se repasarán las causas de protección del accidente de trabajo, y como esta protección sustantiva provocó la creación de órganos judiciales especializados. Se abordará igualmente las causas primeras de la creación de estos órganos y el desarrollo legislativo sustantivo que el accidente de trabajo tuvo desde 1900, observándose cómo, con el desarrollo de la historia a lo largo de más de un siglo, el accidente de trabajo sigue teniendo un papel esencial en el Derecho Social y en su manifestación adjetiva, la jurisdicción social.

GREEN ECONOMY AND GOOD GOVERNANCE TOWARDS INCOME EQUALITY: A QUANTILE ANALYSIS

The world is moving towards a greener economy, a more equal society and better governance under the Sustainable Development Goals (SDGs) and the “Environmental, Social and Governance” initiative. Doubts remain on whether a greener economy and better governance are helpful in achieving income equality. This study aims to examine the relationship between green economy, governance and income inequality, applying quantile regression to capture the different relationships in different levels of income inequality between 2009 and 2019 in 30 countries. The results reveal that green economy proxies are mostly not significant in high-income countries but can aggravate income inequality in middle-income countries at lower quantiles to create a green economy-income inequality trap. Better governance can reduce inequality in high-income countries but worsen inequality in middle-income countries. The findings imply that high-income countries can pursue a sustainable green economy without needing to be concerned about income inequality, which is reduced only with better governance. In contrast, good governance is harmful to income inequality in middle-income countries. It hints at serious fundamental flaws in institutional structure. These are urgent challenges in policy formulation and economic planning regarding the SDGs towards achieving the sustainability trinity of lowering inequality, a greener economy and better governance.

Published: October 2022

The piece explores the prerequisites of implementation of an integrated approach to regulating industrial pollution in Ukraine as well as provides an insight into the legislative proposals on introduction of the integrated environmental permits currently under consideration in the Parliament of Ukraine. The article argues that the proposed regulation corresponds to the respective EU acquis, including the Aarhus Convention. Given that the post-war reconstruction assistance has already been clearly anchored in the green and digital transitions as well as other fundamental European values, it is the authors’ conclusion that the new legal framework on reduction, prevention and control of industrial pollution will be introduced in Ukraine in the nearest future.
SIMRS Network Security Simulation Using Snort IDS and IPS Methods
Authors: Widiyanto Wahyu Wijaya
Published: October 2022

AbstractHospital information systems have an essential role in clinical and administrative services. This triggers an innovation that supports an integrated quality measurement data management system by integrating the Hospital Management Information System (SIMRS). SIMRS can be implemented locally or in the cloud, using the network to exchange data and information. Along with the current development of Information Technology, information security is very important, especially on a network connected to the internet. But what is unfortunate is that developments in the security system itself do not accompany the imbalance between each technological development. This study aims to overview techniques for securing network computers from various attacks through network security simulations. The research method used is using Snort as a detector to perform security on computer networks, while as a system for detecting and preventing intruders on computer network servers using the Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) methods. This study concludes that the IDS system with Snort simulated can detect attacks with the same average accuracy value of 99.97% and produce an average server response time value by good snort rules (1 client is 0.50 seconds, 2 clients are 0.32) seconds.Keywords: network security, snort, IDS, IPS  AbstrakSistem informasi rumah sakit memiliki peran penting dalam pelayanan klinis dan administrasi. Hal ini memicu inovasi yang mendukung sistem pengelolaan data pengukuran mutu yang terintegrasi dengan mengintegrasikan Sistem Informasi Manajemen Rumah Sakit (SIMRS). Implementasi SIMRS dapat dilakukan secara lokal maupun cloud, keduanya menggunakan jaringan untuk bertukar data dan informasi. Seiring dengan perkembangan Teknologi Informasi saat ini, keamanan suatu informasi menjadi sangat penting terutama pada suatu jaringan yang terkoneksi dengan internet. Namun yang disayangkan, ketimpangan antara setiap perkembangan teknologi tersebut tidak dibarengi dengan perkembangan sistem keamanan itu sendiri. Penelitian ini bertujuan untuk memberikan gambaran tentang teknik pengamanan jaringan komputer dari berbagai jenis serangan melalui simulasi keamanan jaringan. Metode penelitian yang digunakan adalah menggunakan Snort sebagai pendeteksi untuk melakukan pengamanan pada jaringan komputer, sedangkan sebagai sistem untuk mendeteksi dan mencegah penyusup pada server jaringan komputer menggunakan metode Intrusion Detection Systems (IDS) dan Intrusion Prevention Systems (IPS). Kesimpulan dari penelitian ini adalah sistem IDS dengan simulasi Snort dapat mendeteksi serangan dengan nilai akurasi rata-rata yang sama yaitu 99,97%, dan menghasilkan nilai rata-rata waktu respon server dengan aturan snort yang baik (1 client adalah 0,50 detik, 2 client adalah 0,32) detik.Kata Kunci: keamanan jaringan, snort, IDS, IPS
