Authors: Buchberger Wolfgang , Oberaigner Willi , Kremser Christian , Gautsch Kurt , Siebert Uwe 
Published: April 2021

Objectives: The purpose of this study was to assess the accuracy of contrast-enhanced magnetic resonance imaging and diffusion-weighted imaging in distinguishing benign from malignant non-mass-like breast lesions. Methods: 103 lesions showing non-mass-like enhancement in 100 consecutive patients were analyzed. Distribution, internal enhancement patterns, and contrast kinetic curve patterns were classified according to the BI-RADS lexicon. Apparent diffusion coefficient (ADC) values were obtained from manually placed regions of interest (ROIs) on diffusion-weighted images. The optimal ADC value threshold for the distinction between benign and malignant lesions was determined by ROC analysis. Univariate and multivariate analyses were performed to identify independent predictors of malignancy, and the probability of malignancy was calculated for various combinations of findings. Histological diagnosis obtained by means of core needle biopsy was used as gold standard. Results: According to the univariate and multivariate analysis, odds ratios for malignancy were significantly elevated for clumped or clustered ring internal enhancement and low ADC values (p < 0.001), whereas distribution patterns and contrast kinetic patterns were not significantly correlated with benignity or malignancy. In non-mass lesions with homogeneous or heterogeneous internal enhancement and ADC values greater than 1.26×10-3mm2/s, no malignancy was detected, while all other combinations of findings had a probability of malignancy ranging from 22.2 to 76.6%. Conclusions: A combination of BI-RADS descriptors of internal enhancement and ADC values is useful for the differential diagnosis of lesions showing non-mass enhancement. Lesions with homogeneous or heterogeneous enhancement and high ADC can be followed up, while all other lesions should be biopsied. Doi: 10.28991/SciMedJ-2021-0302-1 Full Text: PDF
Why did the COVID-19 Epidemic Stop in China and does not Stop in the Rest of the World? (Application of the Two-Component Model)

Published: April 2021

The vastly different courses of the COVID-19 epidemic in China and the rest of the world are investigated and explained within two-component epidemic model. The model is based on separate accounting for the contribution to the epidemic from two types of immune response to a viral infection - innate and adaptive immunity. Any infected person becomes asymptomatic with probability (1−𝑝) or symptomatic with probability 𝑝. In the first case, innate immunity is sufficient to protect a person. In the second case, innate immunity is insufficient, and adaptive immunity comes into play. In the asymptomatic state, the person remains outwardly healthy, mobile and can spread the infection. In the symptomatic state, the person becomes ill, isolated and cannot spread the infection. We assume that the contribution to the epidemic process from asymptomatic carriers is dominant in comparison with the contribution from the usual incubation period in the symptomatic state. The key parameters of the model are the virus lifetime 𝑇 in the asymptomatic state and the spread rate 𝛽. At moderate 𝛽𝑇 values, the model describes a long, slowly decreasing morbidity plateau, which transforms into wave-like solution at 𝛽𝑇. In the case of 𝛽𝑇→∞, which corresponds to a stable non-pathogenic strain, the model solution is limited to single wave only. We believe that the spread of such a non-pathogenic strain and its subsequent dominance is responsible for ending the epidemic after the single wave of incidence in China. A way to stop the epidemic in the rest of the world may consist in displacing the circulating pathogenic virus with its stable non-pathogenic strain. Doi: 10.28991/SciMedJ-2021-0302-2 Full Text: PDF

Bangladesh has experienced long term COVID-19 impact in the education sector where university students have suffered a lot. This cross-sectional study intended to evaluate the health behavior of public university students towards the COVID-19. The convenience sampling technique was employed during the rapid COVID-19 period. A total of 952 public university students participated in the KAP survey. Statistical analyses were performed depending on the data type. Study population demonstrated exemplary COVID-19 knowledge along with positive attitudes and preventive practices towards the COVID-19. Gender, university year, and major were determined as associating factors with their overall KAP. Female students reported better knowledge and practice regarding COVID-19 than their counterpart male students. Students living in the capital Dhaka city did not show positive attitudes towards COVID-19 compared to the students living outside the city. Students who were without their families demonstrated better attitudes compared to the students with their families. Broadcast media, print media, the internet, university, and social media were identified as sources of COVID-19 precautionary measures information for these students. Students showed better knowledge and attitude levels when used print media and university respectively compared to the students who used surrounding people as a source of information. This study enhances our understanding of the health behavior of public university students of Bangladesh. It has also determined the associating factors with their KAP level. The outcome of this study can assist the government, organizations, and the university to prepare for a comprehensive pandemic control effort. Doi: 10.28991/SciMedJ-2021-0302-4 Full Text: PDF

Published: April 2021

Abstract
Meeting customers’ requirements and achieved the right level of product quality is key action of enterprises. It is being done by controlling the product, using for example non-destructive testing (NDT). But the NDT not indicating what is the root of incompatibility. Additionally, previous research does not include the decision methods, which would be related the identify the causes of the problem as part of improving the product quality. Therefore, the aim is supporting the process of improving the product quality level in the context of precisely identify the incompatibility and the root of their occurrence with including the solve decision problem. In this aim, it was assumed that using after the NDT research in connection way: brainstorming, cause and effect diagram, AHP method (Fuzzy Analytic Hierarchy Process) and the 5Why method, will be allowed on effective identify the root of the problem. The method test was carried out for the porosity on a welded mechanical seal made of steel 410, which was identified by the fluorescence method (FPI) in Podkarpacie enterprise. The analysis has shown the effectiveness of using after NDT the combined methods as part of identifying the incompatibility and precisely identifying the root of its occurrence in context of solving the decision problem. The proposed method can be used to improving the quality of other products, for example from the aviation and automotive industry, as part of meeting customer requirements. Originality is the combined NDT research with quality management techniques and supported the process of improving the quality level of the product by implementing in this sequence the fuzzy multicriteria decision method.

Published: April 2021

Abstract
The choice of the operator involves taking risks, especially when changing the way logistics is handled (e.g. from your own warehouse and distribution network to external – outsourced). The aim of the article is to present the most important factors that directly and indirectly influence purchasing decisions made by customers of logistics operators. In order to correctly determine the parameters of the selection of a logistics service provider in terms of quality, it is necessary to define quality requirements criteria that allow to meet specific KPIs (Key Performance Indicators) to measure the satisfaction of the final recipient of the goods. The main goal of the article is to answer the question of how to define criteria to be relevant to customer expectations and how they affect final purchasing decisions in the context of choosing the operator to provide logistics services. In order to illustrate the full picture of the studied environment, as well as to maximally facilitate and encourage respondents to participate in the study, surveys were used mainly in the form of Internet, mostly containing closed and several open questions. The research was based on three research groups: logistics operators, customers of logistics operators and final recipients of services of logistics operators. In the individual groups, the survey invited: 1) about 80 companies from European logistics operators; 2) approx. 150 companies from Central and Western Europe dealing in production and trade according to the classification of economic activity; 3) over 2,000 people who have declared to buy various goods with delivery to the address indicated.
Exploring the Digital Business Ecosystem of Internet of Things in Emerging Economies with a focus on the role of pseudo-private companies
Authors: Saheb Tahereh , Hosseinpouli Mamaghani Faranak 
Published: April 2021

The Internet of Things (IoT) is one of the emerging drivers of the economy that transforms the business landscape and forms of collaboration and value creation. In this study, we performed a Delphi-based study to explore the digital business ecosystem (DBE) of IoT in emerging economies, focusing on power dynamics among actors, the processes of value co-creation, topologies, and critical success factors affecting the health of the ecosystem. We conducted two panels of a three-round Delphi study from 2017 through 2019 among Iranian IoT experts. This study identifies two types of the digital business ecosystems surrounding IoT in Iran. One type comprises only pseudo-private companies that have strong interactions with government organizations and state-owned banks. The other type of digital business ecosystem surrounding IoT technology comprises start-ups and private small and medium companies that have no interaction with pseudo-private companies. The interaction of start-ups and Small Medium Enterprises (SMEs) is mainly with universities. The study shows that pseudo-private companies play a dominant role in the Business to Business (B2B) and Business to Government (B2G) markets while SMEs and start-ups have a dominant role in the B2C market and promote creativity and innovation in the Business to Customer (B2C) market. This study extends the literature on digital business ecosystems with a focus on the health of the DBEs of IoT technologies and the potential for future innovation in the digital economy.
