Assimilation of Nowcast Objects for Rapid Update Cycling
Authors: Neef Lisa , Stephan Klaus , Blahak Ulrich , Welzbacher Christian , Potthast Roland
Published: March 2023

Within the SINFONY project at DWD, we have developed a framework for assimilating convective objects from the cell-identification and -tracking scheme KONRAD3D into NWP forecasts using ICON-LAM. The main idea behind this approach is to additionally constrain modeled convection -- that is, generating missing convection and/or removing spurious convection in the model forecast -- by considering radar reflectivities as coherent objects with associated features, rather than 3-d fields of pixelated information.  This approach is appealing because it harnesses the object-oriented approach taken in nowcasting in order to bring additional information into the NWP forecast, while also reducing the complex 3d radar scans down to a set of 2d fields.

However, it is inherently difficult to evaluate the added value of convection-related observations, because they tend to be effective only in special cases, while long term statistics are still needed to see substantial effects in an assimilation system that is already highly constrained by observations. Here we present a set of experiments that examine what happens when we add different types of object-style observations to a baseline assimilation during the summer 2021 active period. We show the longer-term statistical effect of adding object-type observations, while also illustrating how the state update changes in individal cases.
Convective objects detection using computer vision based on radar images
Authors: Mo Sun-Jin , Park Jin-woo , Gu Ji-Young , Lee seungwoo
Published: March 2023

Weather radar is a meteorological observation equipment that can detect meso-scale meteorological phenomena as well as small-scale convective phenomena at an early stage with high temporal and spatial resolution. This study intends to introduce radar data used in meteorology into other perspectives. Although the physical meaning of radar data variables is more generally used, actual weather forecasting agencies are more sensitive to visible changes in the radar image itself. Computer vision technology is a representative way to directly utilize radar images. It produces new information by identifying and interpreting objects or situations by imitating the human visual cognitive system. In this study, convective echo changes were detected and tracked by computer vision using high temporal resolution of X-band weather radar images observed at 1-minute intervals. For convective echo detection, the background subtraction method was used, and techniques such as the median value and Gaussian filter were also used to minimize the echo detection error. The paths of the detected echoes were predicted using the Kalman filter technique. In order to classify the detected multiple convective echoes into individual objects, the labeling of individual convective echoes was also implemented by giving a certain size and intensity as conditions. Finding and tracking convective echoes in real-time with high spatio-temporal resolution radar images will help detect signals early that can generate severe weather and respond preemptively to hazardous weather.

Integrating KONRAD3D into the nowcasting guidance system NowCastMIX at DWD
Authors: Debertshäuser Michael , James Paul , Werner Manuel
Published: March 2023

Short-term warnings for severe thunderstorms are produced at the German Weather Service (DWD) with the support of NowCastMIX, which automatically creates warning areas for the next 60 minutes. In short, NowCastMIX processes meteorological fields from various sources such as NWP, radar, surface station reports and lightning detections. Based on the available data, the potentials for heavy rain, hail and severe gusts are calculated every 5 minutes by a hierarchy of fuzzy logic sets. From these potentials, categorical thunderstorm warnings are issued for detected cells. By condensing the information into clusters, regions are then identified which require warnings.
One system that NowCastMIX currently uses as input is KONRAD. KONRAD is a method for automatic detection, tracking, and prediction of thunderstorm cells based on two-dimensional weather radar data. In recent years, a new scheme, KONRAD3D, has been developed, which provides three-dimensional objects of detected cells with the help of 3D radar volume scans. KONRAD3D also provides new state-of-the-art approaches to capture features such as the storm track more smoothly and consistently over time.
In order to let NowCastMIX benefit from this new development, KONRAD will be replaced by KONRAD3D. Subsequently, reanalyses with the new KONRAD3D module will be calculated for 194 convective days over a period of three convective seasons. A comparison of both data sets will show in which areas NowCastMIX benefits from the three-dimensional objects provided by KONRAD3D. The fuzzy logic of NowCastMIX will be tuned based on the reanalyses in order to optimize the probability of detection and false alarm ratio for the administrative districts of Germany.
Real-time extremity assessment of rainfall observations and SINFONY forecasts for small hydrological catchments
Authors: Berndt Christian , Bondy Jan , Schultze Markus , Blahak Ulrich
Published: March 2023

Heavy rainfall caused by convection over small catchments represents a major challenge in flood forecasting. In Germany, each federal state runs its own flood forecasting center providing operational forecasts obtained from hydrological models. This system works well for large and medium-sized catchments. However, hydrological response happens fast for small catchments and operational models do not perform well. In many cases, these models only use hourly rainfall observations and NWP forecasts but do not take into account rainfall nowcasts.

We aim at supporting German flood forecasting agencies in a co-design approach. Specifically, we intend to provide a novel post-processing product containing information about the extremity of catchment-specific areal rainfall. First, a nationwide catchment delineation is performed for each pixel of a 50 m x 50 m grid using a digital elevation model, while catchments smaller than 10 km² and greater than 1000 km² are discarded. Next, we perform an upscaling of catchment information to a 1 km x 1 km grid. Finally, we compute areal rainfall for each pixel using the underlying catchment geometry from rain gauge adjusted radar observations as well as seamless rainfall forecasts resulting from the SINFONY project.

We consider various accumulation durations and perform a recalculation of areal rainfall for all catchments using a 20-year dataset of radar-derived rainfall. A partial series of areal rainfall accumulation results for each catchment and we fit extreme value distributions in order to provide information about the expected statistical return period of rainfall events and their potential hydrological impact in real-time. Extreme value statistics with time series of only 20 years is not sufficient to obtain reliable return periods for very rare events. In order overcome this limitation, we include long-term rain gauge statistics and combine them with areal rainfall recalculations in a reasonable manner.

The resulting spatial distribution of areal rainfall with corresponding return periods based on an exhaustive collection of catchments appears to be a useful visualization technique to identify small catchments affected by heavy rainfall and can be computed in real-time using SINFONY products. In order to illustrate the benefit of this approach, we will show a comprehensive case study for the catastrophic flooding event on 14th of July 2021.
Towards a manual-free labelling approach for deep learning-based ice floe instance segmentation in airborne and high-resolution optical satellite images
Authors: Zhang Qin , Hughes Nick
Published: March 2023

Abstract. Floe size distribution (FSD) has become a parameter of great interest in observations of sea ice because of its importance in affecting climate change, marine ecosystems, and human activities in the polar ocean. The sizes of ice floes can range from less than a square metre to hundreds of square kilometres, so the most effective way to monitor FSD in the ice-covered regions is to apply image processing techniques to airborne and satellite remote sensing data. The segmentation of individual ice floes is crucial for obtaining FSD from remotely sensed images, and it is a challenge to separate floes that appear to be connected. Although deep learning (DL) networks have achieved great success in image processing, they still have limitations in this application. A key reason is the lack of sufficient labelled data, which is costly and time-consuming to produce. In order to alleviate this issue, we use classical image processing techniques to achieve a manual-label free ice floe image annotation, which is further used to train DL models for fast and adaptive individual ice floe segmentation, especially for separating visibly connected floes. A post-processing algorithm is also proposed in our work to refine the segmentation. Our approach has been applied to both airborne and high-resolution optical (HRO) satellite images, and successfully derived FSD at local and global scales.
Yeti 1.0: a generalized framework for constructing bottom-up emission inventories from traffic sources at road-link resolutions
Authors: Chan Edward C. , Leitão Joana , Kerschbaumer Andreas , Butler Timothy M.
Published: March 2023

Abstract. This paper outlines the development and operation of Yeti, a
bottom-up traffic emission inventory framework written in the Python 3
scripting language. A generalized representation of traffic activity and
emission data affords a high degree of scalability and flexibility in the
use and execution of Yeti, while accommodating a wide range of details on
topological, traffic, and meteorological data. The resulting traffic
emission data are calculated at a road-level resolution on an hourly basis.
Yeti is initially applied to traffic activity and fleet composition data
provided by the senate administration for the city of Berlin, which serves
as the region of interest, where the Yeti-calculated emissions are highly
consistent with officially reported annual aggregate levels, broken down
according to different exhaust and non-exhaust emission modes. Diurnal
emission profiles on select road segments show not only the dependence on
traffic activities but also on road type and meteorology. These road-level emissions are further classified on the basis of vehicle categories
and Euro emission classes, and the results obtained confirmed the
observations of the city of Berlin and subsequent rectifications.
Sediment transport in Indian rivers high enough to impact satellite gravimetry

Published: March 2023

Abstract. Satellite gravimetry is used to study the global hydrological cycle. It is a key component in the investigation of groundwater depletion on the Indian subcontinent. Terrestrial mass loss caused by river sediment transport is assumed to be below the detection limit in current gravimetric satellites of the Gravity Recovery and Climate Experiment Follow-On mission. Thus, it is not considered in the calculation of terrestrial water storage from such satellite data. However, the Ganges and Brahmaputra rivers, which drain the Indian subcontinent, constitute one of the world's most sediment rich river systems. In this study, we estimate the impact of sediment mass loss within their catchments on gravimetric estimates of trends in the local mass equivalent water height (EWH). We find that for the Ganges-Brahmaputra-Meghna catchment, sediment transport accounts for (4±2) % of the gravity decrease that is currently attributed to groundwater depletion. The sediment is mainly eroded from the Himalayas, where correction for the sediment mass loss reduces the decrease in EWH by 0.22 cm yr-1, which is about 14 % of the EWH trend observed in that region. However, with sediment mass loss in the Brahmaputra catchment resulting to be more than twice that in the Ganges catchment and sediment mainly being eroded from mountain regions, the impact on gravimetric EWH data within the Indo-Gangetic plain, the main region identified for groundwater depletion, results to be comparatively small.
Design and kinematics of a lightweight cruciform continuum robot
Authors: Zhou Pan , Yao Jiantao , Zhang Hongyu , Zhang Xuanhao , kong Shuaiqi , Zhu Kunming
Published: March 2023

Abstract. The design of new lightweight and dexterous configurations is a major
research focus for continuum robotics. This work proposes a cruciform
continuum robot. Its unique feature is that it is formed by multiple
cruciform-arranged elastic sheets with a single dimension of motion
connected in series, and thus it has low-coupling motion characteristics. In
addition, the cruciform continuum robot has the advantages of lighter weight
(65 g), better dexterity, and higher motion accuracy. In this paper, the
forward and inverse kinematics models of the cruciform continuum robot are
established by geometric methods based on the assumption of constant
curvature, and its workspace is analysed. It is experimentally verified that
the tip position errors are less than 1 mm, and the cable length errors are
less than 0.4 mm. Further, the cruciform continuum robot is successfully
used for the nucleic acid detection simulation experiment, which confirms
its good dexterity and man–machine safety. The main contribution of this
paper is to provide a new configuration for the lightweight and dexterous
continuum robots, and to further provide a reference method for improving their
modelling accuracy from the perspective of structure.
Scenario-based modelling of waves generated by sublacustrine explosive eruptions at Lake Taupō, New Zealand
Authors: Hayward Matthew W. , Lane Emily M. , Whittaker Colin N. , Leonard Graham S. , Power William L.
Published: March 2023

Abstract. Volcanogenic tsunami and wave hazard remains less understood than that of other tsunami sources. Volcanoes can generate waves in a multitude of ways, including subaqueous explosions.
Recent events, including a highly explosive eruption at Hunga Tonga-Hunga Ha'apai and subsequent tsunami in January 2022, have reinforced the necessity to explore and quantify volcanic tsunami sources.
We utilise a non-hydrostatic multilayer numerical method to simulate 20 scenarios of sublacustrine explosive eruptions under Lake Taupō, New Zealand, across five locations and four eruption sizes.
Waves propagate around the entire lake within 15 min, and there is a minimum explosive size required to generate significant waves (positive amplitudes incident on foreshore of > 1 m) from the impulsive displacement of water from the eruption itself. This minimum size corresponds to a mass eruption rate of 5.8×107 kg s−1, or VEI 5 equivalent.
Inundation is mapped across five built areas and becomes significant near shore when considering only the two largest sizes, above VEI 5, which preferentially impact areas of low-gradient slope.
In addition, novel hydrographic output is produced showing the impact of incident waves on the Waikato River inlet draining the lake and is potentially useful for future structural impact analysis.
Waves generated from these explosive source types are highly dispersive, resulting in hazard rapidly diminishing with distance from the source.
With improved computational efficiency, a probabilistic study could be formulated and other, potentially more significant, volcanic source mechanisms should be investigated.
Vortex model of the airborne wind energy systems aerodynamic wake
Authors: Trevisi Filippo , Riboldi Carlo Emanuele Dionigi , Croce Alessandro
Published: March 2023

Abstract. Understanding and modelling the aerodynamic wake of airborne wind energy systems (AWESs) is crucial for estimating the performance and defining the design of such systems, as tight trajectories increase induced velocities, and thus decrease the available power, while unnecessarily large trajectories increase power losses due to the gravitational potential energy exchange. The aerodynamic wake is here studied with vortex methods, as momentum methods cannot be applied to AWESs in a physically consistent way. The velocities induced at the AWES from a generic helicoidal vortex filament, trailed by a position on the AWES wing, is modelled with an expression for the near vortex filament and one for the far vortex filament. The near vortex filament is modelled as the first half rotation of the helicoidal filament, where its axial component is neglected. The induced drag due to the near wake, built up from near vortex filaments, is found to be similar to the induced drag the AWES would have in forward flight. The far wake is modelled as two semi-infinite vortex rings cascades with opposite intensity. An approximate solution for the induced axial velocity at the AWES is given as function of the radial (known) and axial (unknown) position of the vortex rings. An explicit and an implicit closure model are introduced to link the axial position of the vortex rings with the other quantities of the model. The aerodynamic model, using the implicit closure model for the far wake, is validated with the lifting line free vortex wake method implemented in QBlade. The model is suitable to be used in time-marching aero-servo-dynamic-elastic simulations and in design and optimization studies.

Reliability of Soft Tissue Vibration Measurement and Number of Steps Demanded during Treadmill Running
Authors: Zhang Qingshan , Hautier Christophe A. , Bonis Chloé , Trama Robin
Published: March 2023

The present study aims to determine the test-retest reliability of the input signal (INPUT) of foot impact and soft tissue vibration (STV) of the lower limb muscles during treadmill running. Twenty-six recreational runners participated in three running trials at constant velocity (10 km/h) within two days. The INPUT and STV of gastrocnemius medialis (GAS) and vastus lateralis (VL) were extracted from 100 steps measured by three triaxial accelerometers. The Intraclass Correlation Coefficient (ICC) was calculated to determine the Intra-trial and Inter-day reliability of the different variables. Intra-trial reliability results indicated that most of the INPUT and GAS STV parameters, except for damping coefficient and setting time, have good to excellent reliability (0.75 < ICC < 0.9) from the beginning of the run (10 steps) to the end. In contrast, only 4 VL STV parameters showed good reliability. Furthermore, inter-trial reliability measured on day one showed that the number of reliable parameters reduced, especially for VL STV, and more steps were required (20 < steps < 80) to achieve good reliability. Inter-day reliability results showed that only one VL STV parameter reached good reliability. Therefore, the present results show that the measurement of the foot impact and the calf muscle vibrations present a good to excellent reliability measured on a single trial and two trials carried out on the same day. The reliability of these parameters remains good when comparing two days of experimentation. We recommend measuring impact and STV parameters during treadmill running in the same session.
Disparity in coronary artery dimensions in diabetic and non-diabetic population undergoing quantitative coronary angiography in South India: a 2-year prospective analysis
Authors: Divia Paul A , Das Ranajit , Subramanyam K , Ashraf SM , Ezhilan J
Published: March 2023

Diabetic subjects have higher prevalence as well as increased risk for coronary artery disease than non-diabetic counterparts. The study was aimed to seek the disparity of vessel diameters among diabetic and non-diabetic patients undergoing quantitative coronary angiography (QCA). The objectives were to compare coronary artery measurements (CAM) between diabetic and non-diabetic patients and also to find the respective segment of coronary artery affected greatest among diabetics by QCA. A cross sectional study was conducted in four cities of India after procuring the sanction for the same from the ethical committee of the pre-selected hospitals of four states in India. Informed consents were obtained. Post CABG, post PCI patients and patient being diabetic for ≥5 years were also excluded from the study. Among total sample population, non-flow limiting coronaries were seen in 1100(27.5%) cases [167 in NFL diabetic and 933 in NFL non-diabetic group]. We had 2890 (72.2%) patients with diseased coronaries. Ten segments of the coronary arteries were taken for diameter measurements namely, LMCA, LAD (O, P), DIAG, LCx (O, P), OM, RCA (O, P), RAM. These coronary diameters were indexed to body surface area (BSA) (mean diameter mm/m2BSA). For all arterial segments both indexed and non-indexed measurements of diabetic patients with NFL coronaries had significantly (p<0.01) smaller arterial segments except for RCA-o. Reduced dimensions after post balloon dilatations of PCI, diffused lesions can result in increased chances for in-stent restenosis among diabetics leading to poor outcome following PCI.
La nueva derecha radical chilena en el contexto internacional: auge e ideología
Authors: Caro Isaac , Quitral Máximo
Published: March 2023

Este artículo aborda el auge y la ideología de una nueva expresión política, que denominados “nueva derecha radical”. Como hipótesis central sostenemos que el auge de esta nueva formación política se debe a los efectos sociales de la crisis subprime de 2008 mientras que su ideología responde a una reacción conservadora o cultural backlash sobre ciertos cambios sociales experimentados por las sociedades modernas, los cuales son percibidos como una amenaza de vivir y de entender el mundo. En términos espaciales, este trabajo toma como ejemplo de expresión de esta nueva derecha radical el caso del partido político chileno Partido Republicano, liderado por el excandidato presidencial, José Antonio Kast. Esta investigación hace hincapié en un estilo documental, que incluye la revisión de fuentes primarias y secundarias, publicaciones académicas, revisión de prensa, la consulta de sitios de internet y particularmente foros sociales (especialmente Twitter) pertenecientes a la nueva derecha radical chilena. Finalmente, esta investigación se enmarca en el campo de la intersección entre la sociología, la ciencia política y los estudios internacionales, adoptando una perspectiva de sociología política internacional.

Published: March 2023

O objetivo deste artigo é discutir questões relacionadas à formação inicial de professores nos cursos de licenciaturas, no que diz respeito aos saberes da prática docente, ao currículo, à didática, aos dispositivos de ordem legal, e a necessidade de reformulação dos projetos pedagógicos dos cursos de licenciaturas, com destaque para a Base Nacional Comum para a Formação Inicial e Continuada de Professores da Educação Básica (mais conhecida como BNC-Formação), homologada em 20 de dezembro de 2019. Trata-se de uma revisão de literatura, baseada na análise de documentos norteadores da formação de profissionais do magistério, como também de autores e pesquisadores que discutem a formação inicial, bem como as tensões teórico-práticas que permeiam essa formação. Consideramos, com base na análise de documentos de autoria de pesquisadores da Anfope e da Anped, os quais repudiaram a BNC-Formação, que a proposta é reducionista no que tange ao trabalho docente e que retrocede na compreensão acerca da indissociabilidade entre teoria e prática, uma discussão já bem assentada no campo educacional.

Relationship between Information and Communication Technologies and Sustainable Development: Fresh Evidence from Group of Seven (G-7) Countries
Authors: Hanif Sobia , Bakar Abou , Nawaz Muhammad Atif
Published: March 2023

There is ongoing discussion about the use of information and communication technologies (ICT) to promote sustainable development. While one side fiercely advocates using ICT technologies to drive and carry out sustainable development, others passionately struggle to highlight their many drawbacks. The present study adds to ongoing discussion by estimating the effect of ICT on sustainable development in G-7 economies over 1995-2020 period, which is an unreached area in the literature. The study also holds its novelty by considering Adjusted Net Savings (ANS) for measurement of sustainable development. As cross sectional dependence (CSD) and slope heterogeneity are present in data, second-generation panel estimation technique Cross sectional Augmented Distributed Lag Model (CS-ARDL) is used for the long run and the short run estimation. The findings assert that ICT technologies have positive effect on sustainable development in G-7 countries. In addition, the study also finds the positive contribution of renewable energy and negative contribution on non-renewable energy in sustainable development of the selected countries. The study recommends the governments to adopt effective policies to implement and improve infrastructure quality in terms of digital technologies to achieve sustainable development in selected economies.

The Values of Gender Equality in the Image of ‘Bifurcated Garments’ for Women
Authors: Lee Hyo-Jin
Published: March 2023

This study is concerned with analyzing how the values of gender equality have been reflected to the development of the image of the ‘bifurcated garments’ for women. Research methodology is a literature survey and a case study. It was done to collect the precedent research papers, specialty books, and publications verified for the ‘bifurcated garments’ being the major keyword of this study and the study-related Internet materials searched with the keyword and derive the comprehensively reliable results through the analysis on that basis. The study results are as follows. The first one is the establishment of fashion image for values of gender equality. The image of the ‘bifurcated garments’ for women played a major role in beauty treatment as well as fashion. The second one is the birth of a new woman. The women who wore reformed dress and were active in social activities were to blame for unchaste and unfeminine acts. But an advanced new woman showing that ‘Wheel’ is ‘New Woman’ was born. The third one is the change of value of femininity. Through the roles of women and the value of femininity after the 20th century, women’s wearing ‘bifurcated garments’ became the role in visualizing the social treatment being the same as that for men. In conclusion, the sociopolitical subject on the values of gender equality was implicated for panning out in the development of the image of the ‘bifurcated garments’ for women.
The Effect of Hair Shop Promotion on Purchasing Behavior and Oral Intention
Authors: Hong Bi-Dan , Jin Yong-Mi
Published: March 2023

Beauty art industry is a big market, Driven by Cut-Throat Competition and changing consumer preferences and social phenomenon, and suffer from a more rational and obvious new operating strategies are needed. Therefore, this study aims to present basic data necessary to find ways to more actively carry out promotion purchase behavior and word of mouth activities in hair shops due to social changes by verifying the effect of hair shop promotion on purchase behavior and word of mouth. As a result, women in their 20s had the highest educational background, unmarried, and vocational students, with an average monthly income of less than 1 million won. As a result of factor analysis on hair shop promotion, purchase behavior, and word of mouth intention all derived a single dimension, and hair salon promotion was found to have a significant effect on purchase behavior and word of mouth intention. The conclusions and suggestions for these results are as follows. First, when planning promotions to expand consumers' purchasing behavior for hair shop promotions, promotions are conducted for various target groups such as age, gender, and occupation, and various media such as advertisements (POP), messages, SNS, and blogs can be used to promote them. Second, it is judged that consumers' word of mouth intention should be further enhanced by conducting review events such as SNS review events, blog review events, and Naver Place review events together. In addition, since the range of preferred promotions is small, it was difficult to accurately investigate the effect on purchasing behavior and word of mouth intention within the range of more diverse promotions to customers. In future studies, it is expected that more detailed improvement plans will be derived from the hair shop promotion initiative of beauty workers through analysis of a wider type of promotion and detailed expansion studies such as gender, region, and age.
GPU-Accelerated High-Fidelity Implicit LES of Coanda Cylinder Flow Instabilities
Authors: Regev Tom
Published: March 2023

This work covers multiple 3D Implicit Large Eddy Simulations covering two cases: The quiescent Coanda cylinder and the Coanda cylinder in a freestream. Previous works have shown RANS is insufficient in resolving Coanda jets, thus requiring higher fidelity tools. PyFR was chosen due to its demonstrated efficiency in running parallel computations on multiple GPUs. For the quiescent case we aim to capture unsteady flow structures observed experimentally around a Coanda cylinder placed in a water tank. Using dyes, image processing and PIV measurements, these experiments were able to capture streamwise counter-rotating vortices (Gortler instabilities) as well as some initial transient structures of interest. Due to the incompressible nature of the experimental setup the case was simulated using PyFR's artificial compressibility solver, making use of the acceleration capabilities available in dual time stepping and the synthetic turbulence generation capabilities of PyFR. In the case of the Coanda cylinder in a freestream our goal is to simulate the CoRe system (Coanda Reciprocating), a wind energy harvesting method involving the creation of reciprocating lift force on a cylinder by alternate blowing of air through opposing slots on a cylinder perpendicular to the wind direction. For the second case simulations were performed using PyFR's compressible solver due to the local Mach number crossing into the incompressible range. Simulations of the quiescent case were able to qualitatively capture both the counter rotating structures and the initial transients, though quantitative comparison of vorticity magnitude and vortex structure size shows a discrepancy from the experimental measurements. For the freestream case simulations were able to accurately capture the time averaged pressure distribution on the cylinder for momentum coefficients above 0.06, as well as the alternating lift force, though a large deviation in the drag force prediction was observed.
A prospective observational study to evaluate the safety of COVID-19 mRNA vaccines administered to Qatar Rehabilitation Institute patients
Authors: Noureddine Zahra , Madi Lama , Ullah Sami , Alrawashdeh Haneen , Naseralallah Lina
Published: March 2023

Background: The safety of the COVID-19 mRNA vaccine in the outpatient setting has been extensively studied; however, there need to be more reports that specifically assess their safety in the inpatient population. It is hence imperative to explore the adverse drug reaction (ADR) profile in this population and monitor the progression of these ADRs in a hospital setting. This provides a unique opportunity to closely observe patients to ensure no side effects go undiagnosed. This study aims to explore and quantify the incidence and severity of ADRs in patients who have received the COVID-19 vaccine during their stay in the rehabilitation facility.

Methods: This is a prospective observational study, which included adult patients admitted to the rehabilitation facility who were deemed eligible to receive the COVID-19 vaccine during their hospital stay. Data were collected by the investigators from June 2021 to May 2022 at 24 hours, 48 hours, and 7 days post-vaccination. A piloted data collection tool was utilized.

Results: Thirty-five patients met the inclusion criteria. Pain at the injection site was the most commonly reported local ADR, while headache was the most frequent systemic ADR. The majority of the reported ADRs were mild to moderate in nature, with only one severe reaction detected. Although no statistical significance was noted among the variables, common patterns were identified, such as a higher occurrence of fever at 24 hours after the second dose as opposed to the first dose. Close monitoring of the included study subjects did not reveal any unanticipated ADRs or an increase in ADRs susceptibility and severity compared to the general population.

Conclusion: This study supports the initiation of vaccination campaigns in inpatient rehabilitation settings. This approach would offer the advantage of gaining full immunity and reducing the risk of contracting COVID-19 infection and complications once discharged.

This study explores the possibilities for digital transformation of small and mediumsized enterprises (SMEs) in the European Union (EU) caused by the pandemic crisis. The research is a methodological foray into the main perspectives of their digital transformation. According to the study carried out, we can say that a large part of SMEs in the EU area have been dramatically affected by the pandemic crisis, they being forced to identify solutions to ensure viability, new competitive advantages that give them the opportunity to increase their organizational performance, to enter new markets, to effectively overcome the barriers imposed by the crisis. At the same time, SMEs in the EU face a multitude of challenges in implementing information technologies (IT), and the results of the analyses carried out show that over 81% of large enterprises already used IT technologies during 2021, while only 37% of SMEs in the EU had IT technologies in place.

Peanut butter processing companies are facing challenges in meeting food safety regulations leading to product recalls by the regulators. There is a claim in literature that sustainability can improve company performance, despite the lack of there being no empirical study to establish whether there is a relationship between deployment of sustainable operations management practices and the level of regulatory compliance for peanut butter processing establishments in Zambia. The research utilized a descriptive correlational research design, where a 5-point rating scale was used to collect quantitative data, in a face-to-face interview from n=12 managers. The collected data was analyzed in IBM SPSS Version 21 to obtain means, standard deviations, and Spearman’s correlation coefficients. The descriptive study showed a ‘low’ to ‘average’ extent of deployment in product and process design, procurement, and quality management. The descriptive study further showed a ‘low’ to ‘average’ level of compliance of the peanut butter for most establishments. The overall results of the correlational study indicate that improving the extent of deployment of sustainable practices can spur improved level of compliance. It is recommended that managers invest in deploying sustainable practices to spur an improved level of compliance in the areas of procurement, quality and product and process design. Further research is needed to establish reasons for not deploying practices and include operations decision areas such as capacity and organizational structures in the research.
ACCOUNTING AS A TOOL FOR CORRUPTION CONTROL IN THE PUBLIC SECTOR IN KENYA
Authors: Dr. Chesoli  , Wafula Joshua
Published: March 2023

The culture of corruption has grown deep roots in the Kenyan society and become endemic. Institutions, which were designed for the regulation of the relationships between citizens and the State, are being used instead for the personal enrichment of public officials.  Corruption persists in Kenya primarily because there are people in power who benefit from it and the existing governance institutions lack both the will and capacity to stop them from doing so. This paper looked at the role of accounting on how to control corruption in the Kenyan Public Sector and the rate of existing internal control and accounting standards are helping to reduce the level of corruption. The main objective of the study is to establish whether internal control and accounting standards have significant relationship with corruption control in the public sector in Kenya. The study got primary data using a structured questionnaire while secondary data were obtained from reports. To test for reliability of result from data used, the Cronbach alpha coefficient was applied. Questionnaires were administered to staff in Kenyan ministries. Respondents were selected using stratified random sampling method. Multiple regression analysis result showed that both internal control and accounting standards do not have significant relationship and effect on corruption control in the Kenyan Public Sector. The recommendations of the study showed that management personnel should at least have basic knowledge of accounting while staff in the accounts and finance department needs to proceed regularly on capacity building to upgrade emerging accounting trends.
RGB COLOR WHEEL INTENDED TO CREATE COLOR HARMONY COMPOSITIONS IN MODERN ART AND DESIGN
Authors: Sofia Shishmanova Prof. Dr. , Rinaldi Aneta
Published: March 2023

The existing RYB color wheel widely used to create harmonic color compositions is not applicable in modern digital art and design. The reason is that colors formed by light, “additive colors”, and those formed by pigments, “subtractive colors” did in fact operate by different rules, and had different primary and complementary colors. So new color wheel is proposed - “RGB color wheel” suitable .to work with colors in digital environment. 

The RGB color wheel is based on the primary colors R, G, B, defined by sRGB color space, create by additive mixing 3 secondary and 6 tertiary harmonic colors with which many different types of harmonic color compositions can be realized.

An analogue RGB color wheel is proposed with pastel colors suitable for print.

New definitions for Hue, Saturation and Lightness color-making attributes are formulated which correspond to the contemporary high level of computer technologies.

There are some recommendations how the new RGB color wheel can be used with the HSB model to create attractive and pleasant images with color harmony in digital design.

Published: March 2023

Thrombotic diseases are increasingly becoming among the prominent causes of death across the globe. Researchers are now turning attention towards fibrinolytic enzymes as potential alternative treatment for thrombolytic diseases. This present study focused on the production of extracellular fibrinolytic enzyme from soil Actinobacteria and evaluation of its hydrolytic activity on blood clot. The Actinobacteria was isolated from compost soil of semi-arid climate in Nigeria. Bacterial isolation was achieved using starch casein agar. Potent fibrinolytic enzyme producing Actinobacteria were identified and subjected to enzyme production using submerged fermentation method. The interactive effects of incubation time, temperature, pH and media components on enzyme production were analysed. Extracellular fibrinolytic enzyme produced by the selected Actinobacteria was partially purified by ammonium sulphate precipitation and subsequently assayed for blood clot lysis activity. Results of these studies indicated that fibrinolytic enzyme was produced optimally at pH 8 and temperature of 40 oC after 72 hour of fermentation. Partially purified fibrinolytic enzyme was able to degrade blood clot comparable to the positive control. These results shows that soil Actinobacteria of unexplored semi-arid climate of Nigeria present a prospect in search of novel microorganisms with potentials in the production of fibrinolytic enzyme that can serve as an alternative blood clot buster in treating thrombolytic diseases.
