Impact of Changes to Procedures on the Evaluation of the Effectiveness of Forms of Professional Activation in Poland
Authors: Bieszk-Stolorz Beata , Dmytrów Krzysztof
Published: June 2021

Active labour market policy is connected with the necessity to account for the funds allocated for it. The conducted analysis forms a part of research on the evaluation of the effects of changes introduced by legal regulations. The aim of this research is to assess the impact of changes to the methodology of calculating on values of the cost and employment effectiveness of basic forms of economic activation in Poland. They were introduced in 2015 in connection with ongoing discussion regarding the effectiveness of the evaluation methods used. The Ministry of Economic Development, Labour and Technology is currently responsible for activating the unemployed in Poland, and funds come from the Labour Fund. The analysis used is the regression discontinuity design. This analysis showed that significant changes occurred only in the slope of the regression line for cost effectiveness after 2015 for both procedures of its calculation. This shows that the new, introduced methods of calculating effectiveness were cosmetic in nature and did not significantly affect their values. A good recommendation for improving the method of evaluating forms of economic activation of the unemployed could be to extend the time of required employment.

Published: June 2021

The effect of polyphenol removal (“dephenol”) combined with an alkaline pH shift treatment on the O/W interfacial and emulsifying properties of canola seed protein isolate (CPI) was investigated. Canola seed flour was subjected to solvent extraction to remove phenolic compounds, from which prepared CPI was exposed to a pH12 shift to modify the protein structure. Dephenoled CPI had a light color when compared with an intense dark color for the control CPI. Up to 53% of phenolics were removed from the CPI after the extraction with 70% ethanol. Dephenoled CPI showed a partially unfolded structure and increased surface hydrophobicity and solubility. The particle size increased slightly, indicating that soluble protein aggregates formed after the phenol removal. The pH12 shift induced further unfolding and decreased protein particle size. Dephenoled CPI had a reduced β subunit content but an enrichment of disulfide-linked oligopeptides. Dephenol improved the interfacial rheology and emulsifying properties of CPI. Although phenol removal did not promote peptic digestion and lipolysis, it facilitated tryptic disruption of the emulsion particles due to enhanced proteolysis. In summary, dephenol accentuated the effect of the pH shift to improve the overall emulsifying properties of CPI and emulsion in in vitro digestion.

Published: June 2021

Nowadays, there is a growing interest in pro-environmental foods produced by pro-environmental practices. However, consumers’ payment motivations towards such foods are currently poorly understood. This manuscript provided a critical investigation of Chinese consumers’ intention to pay a premium (ITPP) for rice grown with green manure as crop fertilizer (GMR). One focus was the establishment of an explanatory structural research framework that includes effects of environmental behavior spillover (EBS) and public information induction (PII); another focus was to analyze the impacts of the selected structural elements on ITPP by introducing education as a moderator. Results suggest that consumers’ ITPP can be largely influenced by PII, therefore, for GMR marketers and policy makers, measures should be developed to widen consumers’ access to public information related to GMR and to improve their capacity of screening effective information. EBS, when ITPP remains low, emerged as a pivotal predictor of consumers’ ITPP. This observation provides us with the enlightenment that breeding consumers’ daily environmental behaviors is highly valued to inspire their payment intention in the early stages of GMR market development. Another finding is that, with the introduction of the educational variable, the influence coefficients of EBS and PII on ITPP increased from 0.42 and 0.53 to 0.61 and 0.66, respectively, which means that it is possible to boost consumers’ payment intention by improving their educational attainment. This study contributes to the existing literature by providing empirical evidence for the GMR industrial upgrading strategy and have significant implications for the environmental governance of the agricultural sector.

Penicillium phytopathogenic species provoke severe postharvest disease and economic losses. Penicillium expansum is the main pome fruit phytopathogen while Penicillium digitatum and Penicillium italicum cause citrus green and blue mold, respectively. Control strategies rely on the use of synthetic fungicides, but the appearance of resistant strains and safety concerns have led to the search for new antifungals. Here, the potential application of different antifungal proteins (AFPs) including the three Penicillium chrysogenum proteins (PAF, PAFB and PAFC), as well as the Neosartorya fischeri NFAP2 protein to control Penicillium decay, has been evaluated. PAFB was the most potent AFP against P. digitatum, P. italicum and P. expansum, PAFC and NFAP2 showed moderate antifungal activity, whereas PAF was the least active protein. In fruit protection assays, PAFB provoked a reduction of the incidence of infections caused by P. digitatum and P. italicum in oranges and by P. expansum in apples. A combination of AFPs did not result in an increase in the efficacy of disease control. In conclusion, this study expands the antifungal inhibition spectrum of the AFPs evaluated, and demonstrates that AFPs act in a species-specific manner. PAFB is a promising alternative compound to control Penicillium postharvest fruit decay.

Cancer and Thrombosis: New Treatments, New Challenges
Authors: Dahm Anders Erik Astrup
Published: June 2021

The direct-acting oral anticoagulant (DOAC) has become an alternative to low-molecular-weight heparin (LMWH) for treatment and prophylaxis of venous thromboembolism (VTE) in cancer patients. The clinicians are, however, faced with difficult decisions regarding DOAC treatment: Which patients cannot use DOACs? Should incidental VTE be treated similar to symptomatic VTE? Is it safe to give DOACs to patients with gastrointestinal or urogenital cancers? How about drug–drug interactions? Should all cancer patients receive thromboprophylaxis? Is arterial thrombosis a problem? The current article reviews the available literature regarding these questions and aims to provide practical solutions based on data from the clinical trials and new guidelines.

Pasteurellosis in farmed lumpsuckers, Cyclopterus lumpus, has emerged as a serious disease in Norwegian aquaculture in recent years. Genomic characterization of the causative agent is essential in understanding the biology of the bacteria involved and in devising an efficient preventive strategy. The genomes of two clinical Pasteurella atlantica isolates were sequenced (≈2.3 Mbp), and phylogenetic analysis confirmed their position as a novel species within the Pasteurellaceae. In silico analyses revealed 11 genomic islands and 5 prophages, highlighting the potential of mobile elements as driving forces in the evolution of this species. The previously documented pathogenicity of P. atlantica is strongly supported by the current study, and 17 target genes were recognized as putative primary drivers of pathogenicity. The expression level of a predicted vaccine target, an uncharacterized adhesin protein, was significantly increased in both broth culture and following the exposure of P. atlantica to lumpsucker head kidney leucocytes. Based on in silico and functional analyses, the strongest gene target candidates will be prioritized in future vaccine development efforts to prevent future pasteurellosis outbreaks.

Published: June 2021

OmpA, which encodes outer membrane protein A (OmpA), is the most abundant transcript in Stenotrophomonas maltophilia based on transcriptome analyses. The functions of OmpA, including adhesion, biofilm formation, drug resistance, and immune response targets, have been reported in some microorganisms, but few functions are known in S. maltophilia. This study aimed to elucidate the relationship between OmpA and swimming motility in S. maltophilia. KJΔOmpA, an ompA mutant, displayed compromised swimming and failure of conjugation-mediated plasmid transportation. The hierarchical organization of flagella synthesis genes in S. maltophilia was established by referencing the Pseudomonas aeruginosa model and was confirmed using mutant construction, qRT-PCR, and functional assays. Distinct from the P. aeruginosa model, rpoN, rather than fleQ and fliA, was at the top of the flagellar regulatory cascade in S. maltophilia. To elucidate the underlying mechanism responsible for ΔompA-mediated swimming compromise, transcriptome analysis of KJ and KJΔOmpA was performed and revealed rpoN downregulation in KJΔOmpA as the key element. The involvement of rpoN in ΔompA-mediated swimming compromise was verified using rpoN complementation, qRT-PCR, and function assays. Collectively, OmpA, which contributes to bacterial conjugation and swimming, is a promising target for adjuvant design in S. maltophilia.

Published: June 2021

Although refrigeration and modified-atmosphere packaging (MAP) allow for an extended shelf life of cooked charcuterie products, they are still susceptible to bacterial spoilage. To obtain better insights into factors that govern product deterioration, ample information is needed on the associated microbiota. In this study, sliced MAP cooked ham and cooked chicken samples were subjected to culture-dependent and culture-independent microbial analysis. In total, 683 bacterial isolates were obtained and identified from 60 samples collected throughout the storage period. For both charcuterie types, lactic acid bacteria (LAB) constituted the most abundant microbial group. In cooked ham, Brochothrix thermosphacta was highly abundant at the beginning of the shelf-life period, but was later overtaken by Leuconostoc carnosum and Lactococcus piscium. For cooked chicken products, Latilactobacillus sakei was most abundant throughout the entire period. Additionally, 13 cooked ham and 16 cooked chicken samples were analyzed using metabarcoding. Findings obtained with this method were generally in accordance with the results from the culture-dependent approach, yet they additionally demonstrated the presence of Photobacterium at the beginning of the shelf-life period in both product types. The results indicated that combining culture-dependent methods with metabarcoding can give complementary insights into the evolution of microorganisms in perishable foods.

Published: June 2021

The aim of the study was to assess the influence of the addition of an oxygenated additive (a mixture of mono-, di- and triacetylglycerol obtained from residual glycerin within the biodiesel production scheme) on the specific fuel consumption and exhaust emissions of a EURO 3 diesel bus during its daily route through the city. To do this, the urban bus was fuelled with five fuel blends of diesel (D), biodiesel (B), additive (A) and heptanol as co-surfactant (H). A portable emissions measurement system was used to measure the exhaust gases while an engine exhaust particle system with a dilution system, both installed on the urban bus, was used for nanoparticles measurement in actual operating conditions through the city of Seville. Results showed that B95A5 (95%v/v biodiesel, 5%v/v additive) and B90A10 were the blends that most increased NOx emissions (by 24.12% and 9.85%, respectively) compared to D100. On the other hand, B47.5D47.5A2.5H2.5 was the blend that most reduced total particle number (by 31.6%) and NOx emissions (by 12%). All in all, the oxygenated additive can be efficiently blended with biodiesel to reduce particle emissions from engines without diesel particle filter, such as those in urban buses in many European cities.

Published: June 2021

Young adults enrolled in collegiate agricultural programs are a critical audience for agricultural health and safety training. Understanding the farm tasks that young adults engage in is necessary for tailoring health and safety education. The project analyzed evaluation survey responses from the Gear Up for Ag Health and Safety™ program, including reported agricultural tasks, safety concerns, frequency of discussing health and safety concerns with healthcare providers, safety behaviors, and future career plans. The most common tasks reported included operation of machinery and grain-handling. Most participants intended to work on a family-owned agricultural operation or for an agribusiness/cooperative following graduation. Reported safety behaviors (hearing protection, eye protection, and sunscreen use when performing outdoor tasks) differed by gender and education type. Male community college and university participants reported higher rates of “near-misses” and crashes when operating equipment on the roadway. One-third of participants reported discussing agricultural health and safety issues with their medical provider, while 72% were concerned about the health and safety of their family and co-workers in agriculture. These findings provide guidance for better development of agricultural health and safety programs addressing this population—future trainings should be uniquely tailored, accounting for gender and educational differences.

Published: May 2021

Non-steroidal anti-inflammatory drugs (NSAIDs) are included in a pharmacological group of drugs with different chemical structures providing anti-inflammatory, analgesic and antipyretic actions, as well as antiplatelet action to a certain degree. Unfortunately, NSAIDs can cause a wide range of adverse reactions (AR) posing a serious risk to the health and life of patients. Therefore, the rational use of NSAIDs should include methods for effective prevention of drug complications. Many NSAIDs have a pronounced therapeutic effect, simultaneously causing many undesirable effects, so the drug shall be chosen considering the development of predicted side effects and modern algorithms. According to clinical recommendations, risk factors and administration of safer NSAIDs shall be considered as the main prevention method. Besides, it is possible to protect the patient from the upper gastrointestinal tract complications using proton pump inhibitors. It should be noted that there are no effective medication methods for kidney and liver protection to reduce the risk of NSAID-associated complications.

Degenerative-dystrophic hip damages are among urgent problems, for which endoprosthesis replacement is considered a relevant solution for 100 to 300 cases per 100,000 population per year. Aseptic instability of the endoprosthesis components dominates the environment of unsatisfactory outcomes in the long term. To prevent aseptic instability of the hip endoprosthesis components in the hip pathology, the authors propose a method of "incision" on the tendon part m. iliopsoas and use of the intraoperative method to determine the centre of the endoprosthesis head rotation. This work analyses the surgical treatment method of 103 patients operated on in the traditional way and 91 patients who underwent surgical incision of the m.iliopsoas tendon using the intraoperative method to determine the centre of the endoprosthesis head rotation.
Adverse reactions during chemotherapy: skin toxicity
Authors: Maksimov Maksim Leonidovich , Ismailova Malika Anarbekovna
Published: May 2021

Chemotherapy of oncological diseases is associated with high toxicity. The occurrence of various toxic reactions during the use of antitumor drugs is explained by the fact that most antitumor medicines are not strictly specific, therefore, their effect can extend not only to tumor cells, but also to normal cells, especially to tissues with rapid proliferation. All antitumour agents have skin toxicity in one form or another. However, for some chemotherapeutic agents, skin toxicity is a kind of «reflection» of certain mechanisms of drugs action, and, in most cases, the severity of dermatological reactions correlates with the effectiveness of chemotherapy. Dermatological toxicity deserves special attention, as it affects the quality of life of cancer patients and, in some cases, may require a dose reduction or even cancellation of chemotherapy. This article presents current data on the mechanisms of development of skin toxicity of routine chemotherapeutic agents, growth factor inhibitors and some antitumor antibiotics, its correction and prevention opportunities.

Purpose: This study aimed to evaluate the safety and feasibility of single-port laparoscopic surgery (SLS) for appendiceal mucinous neoplasm (AMN) when compared with conventional laparoscopic surgery (CLS).Methods: This retrospective study enrolled patients who underwent surgery for AMN between July 2014 and June 2020 at Seoul National University Bundang Hospital. Patient demographics, surgical data, pathology, hospital stay, postoperative morbidity, and follow-up data were extracted from electronic records for analysis.Results: We enrolled 18 patients who underwent SLS and 22 who underwent CLS. The SLS group included patients who underwent partial cecectomy (14 patients), ileocecectomy (3 patients), and right hemicolectomy (1 patient). The CLS group included patients who underwent appendectomy (4 patients), partial cecectomy (11 patients), ileocecectomy (5 patients), and right hemicolectomy (2 patients). Operation type was not significantly different between groups (P = 0.213). No patient required open surgery in the SLS group in contrast to the CLS group (13.6%; P = 0.238). The operative time tended to be shorter in the SLS group than the CLS group (median [interquartile range]: 52.5 minutes [40–65.2 minutes] and 60 minutes [40–120 minutes], respectively; P = 0.251). Morbidity was 5.5% in the SLS group and 9.0% in the CLS group (P = 0.692). Surgical margins were clear in all cases. The median duration of postoperative hospital stay was 2.0 and 4.0 days in the SLS and CLS groups, respectively (P = 0.013). No recurrence occurred in either group during follow-up.Conclusion: This study indicates that SLS is a safe and feasible surgical approach for AMN.

The main task of the implementation of environmental policy is to create a resource-efficient system for the placement and disposal of industrial waste and secondary raw materials, in particular, in the production of building materials and products of specified properties. Within the framework of these studies, issues related to the activation of microsilica, which is a waste of ferroalloy production, and methods of its use for modifying the structure of cement stone, in particular, for heavy concrete, are considered. The mechanism of the structure formation process, the method of introduction and the optimal consumption of the additive for modifying the concrete mixture have been determined. With the help of a comprehensive study, the products of dispersion of microsilica, which is part of the complex modifier, have been determined. It has been established that the process of the chemical activation of mineral particles has not been sufficiently studied, in this regard, the presented studies, which consist in finding solutions to increase the operational characteristics due to the process of pretreatment of microsilica with an alkaline medium pH = 10.2 together with a micro-reinforcing component, are relevant. The aim of the study is to establish the positive effect of the activation process of silica fume together with a micro-reinforcing component on the modification of the structure of heavy concrete to increase the hydrophysical properties. The object of research is a modified heavy concrete based on activated microsilica with a micro-reinforcing component. In this work, the following research methods were used: physicochemical activation of microsilica with water, treated by electrolysis with the Melesta device; determination of the frost resistance grade in the WK3 180/40 climatic chamber; water tightness was determined in the UVB-MG4.01 installation; water absorption was determined using a SNOL electric digital oven. Research results: a positive effect on the hydrophysical properties of heavy concrete was established by reducing the content of the binder (cement) and replacing it with a microdispersed filler previously activated with an alkaline medium with pH = 10.2. Further modification with a complex additive (high-water-reducing additive "MasterGlenium 115" with a consumption of 1% plus a reaction-chemical additive with microsilica grade MKU-95 - 15% of the binder mass) together with basalt fiber, improves the following characteristics: water absorption - 2%; waterproof grade - W14; frost resistance - F600, which makes it possible to apply this composition in practice to obtain building products and structures with specified characteristics in harsh operating conditions.

On the basis of the carried out experimental and numerical studies, the mechanism of crack formation in the masonry of the face layer with flexible ties under temperature influences has been established. Experimental studies were carried out for five years on a floor-high fragment of a building formed by external three-layer walls resting on a monolithic reinforced concrete slab. Numerical studies were carried out using the author's specialized program for calculating masonry structures, which implements the finite element method, taking into account structural nonlinearity. The program was verified by comparing the calculation results with the experimental data, as well as at the stage before the formation of cracks using the LIRA-SAPR program. It is shown that, depending on the ratio of the tensile strength of the masonry along the vertical joints and the cut along the horizontal mortar joints, different variants of crack development are possible. Vertical cracks, like expansion joints, reduce tensile and shear stresses. Cutting the masonry along the horizontal mortar joint at the base of the wall leads to a reduction in the length of the area of influence of the floor slab. Together, this leads to a decrease in the level of tensile and tangential stresses and damping of the crack propagation process. At the top of the wall, the effect of the floor slab on the stress-strain state of the masonry is relatively small and the temperature deformations there are close to free. This made it possible to apply a simplified methodology for assessing the crack opening width. A method is proposed for calculating the facing layer masonry for temperature effects and for assigning distances between vertical expansion joints.

The calculation of the resistance of piles in the foundation is proposed according to an extended scheme, which includes the surrounding soil, which is inextricably connected with the pile through the side surface. The implementation of the extended scheme is possible with the application of the method of testing a model pile with a constantly increasing load with continuous measurement of precipitation (CRL method), supplemented by measurements of soil deformations relative to the pile surface and displacements of deep marks near the pile. Increasing the amount of information about the state of the soil allows us to obtain the values of additional forces elastically transmitted to neighboring piles, depending on the size of the areas of plastic deformation of the soil. The assessment of the mutual influence of piles during the increase in load on the foundation makes it possible to choose the best option of its parameters, including the size of piles, their placement in the foundation, changes in resistance and settlement over time.

The high cost of ceramic pigments contributes to the expansion of research on their replacement with large-tonnage industrial waste. Charge compositions based on low-quality clay raw materials with additions of wollastonite with a dispersion of 10 microns (OOO Tekhnokhim, Novosibirsk) and waste of ferrosilicomanganese deposited in bag filters (West Siberian electrometallurgical plant, Novokuznetsk) were tested. It was found that the introduction of 9 wt. % wollastonite and 5 wt. % waste in semi-dry pressing leads to a content of 15 wt. % wollastonite - 2M with a maximum specimen strength of 45.5 MPa and water absorption of 14 wt. %. Refusal to use the addition of wollastonite with an increase in the dosage of the waste to 10 wt. % made it possible to reduce water absorption to 11.5 wt.% without loss of strength. The color of the che-turnip is dark chocolate.

Evolusi, Kepegarian, dan Spiritualitas: Memahami Realitas Pandemi dan Pasca-Pandemi Berdasarkan Pemikiran Ilia Delio
Authors: Bungaran Stepanus Ammai
Published: May 2021

This article assesses the pandemic and post-pandemic situation from a theological lens. The Covid-19 pandemic abruptly halted the order of life. Covid-19 imposes a new lifestyle that seems to persist even after the pandemic is considered to have passed. In this regard, it is no longer possible to see the pandemic as "abnormal."  The best option for understanding the pandemic is to accept it as a new reality and respond to it accordingly, including spiritually. The word "spiritual" in this article refers to realizing the significance of Christ's presence during the pandemic and even after the pandemic. In a very dynamic and utterly uncertain world, it takes an effort to live in Christ, which is also very dynamic and emerges in and through uncertainty. This idea is constructed based on emergentism and evolution, in particular Ilia Delio's idea about The Emergent Christ, and Gordon Kaufman's ideas about serendipitous creativity. The goal is to understand Christ as a certainty as well as uncertainty and as a spiritual way of living in the pandemic and post-pandemic. By living the uncertain Christ, Christian spirituality is being invited to live a love that is embracing, unifying, and always new. This spirituality is what is needed to support pandemic and post-pandemic life.AbstrakTulisan ini merupakan sebuah upaya memahami pandemi dan pasca-pandemi dari lensa teologi. Pandemi Covid -19 tiba-tiba saja mengubah tatanan kehidupan. Covid-19 memaksakan laku hidup baru yang tampaknya akan menjadi kesehari-harian bahkan setelah pandemi ini dianggap berlalu. Dalam konteks ini, pandemi tidak mungkin lagi dilihat sebagai kondisi “abnormal.” Pilihan terbaik memahami pandemi adalah menerimanya sebagai realitas baru dan meresponnya secara wajar, termasuk secara spiritual. Kata “spiritual” dalam tulisan mengarah sebuah upaya melihat signi-fikansi kehadiran Kristus dalam pendemi bahkan pasca-pandemi. Dalam dunia yang sangat dinamis dan serba tidak pasti, dibutuhkan sebuah upaya menghidupi Kristus yang juga sangat dinamis dan muncul di dalam dan melalui ketidakpastian. Tulisan ini merupakan undangan memahami Kristus sebagai kepastian sekaligus ketidakpastian sebagai jalan spiritual menghidupi pandemi dan pasca-pandemi. Gagasan ini dikon-struksi dari perspektif kepegarian, evolusi, gagasan Delio tentang The Emergent Christ, dan gagasan Kaufman tentang Serendipitous Creativity. Dengan menghidupi Kristus yang tidak pasti, spiritualitas Kristen sesungguhnya sedang diundang meng-hidupi cinta yang merengkuh, menyatukan, dan selalu baru. Spiritualitas inilah yang dibutuhkan menghidupi pandemi dan pasca pandemi.
