Authors: Servátková Mária , Chlebo Peter , Chlebová Zuzana
Published: July 2020

The benefit of the nutritional support provided to patients with colorectal cancer who have undergone the planned resection of the colon in relation to the laboratory markers of nutrition was examined. And it is currently being discussed, that pre-operative optimization of nutritional status reduces the incidence of post-operative complications in cancer patients and regulates selected laboratory parameters. This was a retrospective study where the treatment group (n = 52) received the enteral nutritional support 21 days prior to the scheduled surgery and the other group was formed of patients without preoperative enteral nutrition (n = 52). Laboratory parameters (CRP, leukocytes, albumin, total proteins) were monitored for at least one month before the planned surgery and just before the operation, and the effect of supplemental enteral nutrition on selected laboratory parameters between these two groups was compared. In a group of patients with enteral nutrition, serum albumin levels increased significantly, while CRP was significantly reduced during preoperative enteral nutrition (albumin S-ALB from 35.42 to 37.48, p = 0.0008, C reactive protein from 26.5 to 14.092, p = 0.0007). Nutritional support 21 days prior to surgery in oncological patients resulted in an improvement in laboratory parameters compared to the group of patients without nutritional enteric support. Malnutrition in patients who are candidates for major surgical intervention is a risk factor for postoperative morbidity and mortality. However, further studies are required to verify the effectiveness of this early nutritional intervention on medium and long-term clinical parameters in different types of cancer.

This work is focused on the determination of antiradical activity (ARA) by the method of free radical scavenging of 2,2-Diphenyl-1-picrylhydrazyl (DPPH). Since the DPPH solution is intense purple-coloured and absorbs at a wavelength of 517 nm, similar to the anthocyanin colorants of fruits, the modification of the method examined the effect of the colour of the sample extracts on the result of the ARA determination. Statistical evaluation of the results of the analyses using Youden's graphing method revealed that the two compared method adjustments gave consistent results over the observed range of antiradical activity. It also showed that there was no statistically significant difference between the mean ARA values obtained by the two treatments. Investigation of the effect of the evaluated fruit components revealed a strong correlation between the content of ascorbic acid and ARA in samples containing no anthocyanin colorants. For the fruit samples studied, ARA values showed a strong correlation with polyphenol content.

Published: July 2020

This study identifies and discusses six technologies that affect recruitment and selection approaches using an American multinational company (AMNC) as a case study. It indicates that technology-based recruitment and selection approaches have had a noticeable impact on the AMNC’s recruitment and selection processes and practices in general, and the three stakeholders (human resource- HR- managers, hiring managers, and job-applicants) in particular. It concludes that the use of technology-based recruitment and selection approaches is not the matter of choice but is a requirement for the success of any company. It also offers the study’s implications and future research directions.
The Return: The Long Road Home of Female Concentration Camp Inmates
Authors: Muller Anna
Published: July 2020

In this article, while focusing on non-Jewish female prisoners who returned to Poland soon after the war, I examine the place of female support and friendship in the years immediately following the Second World War. It is based on a collection of letters that Joanna Muszkowska Penson and a group of her friends began exchanging soon after their departure from Ravensbrück, in the span of seven months from May to December 1945. Oral interviews with three authors of the letters—Joanna Muszkowska-Penson, Alicja Gawlikowska, and Urszula Głowacka—supplement the letters. The article looks at the scope, nature, and role of this female support network in women’s return to postwar life. The letters offer insight into the survival strategies that the women employed after their exit from the camp, which they based mostly on the relationships that developed in camp and continued after the war. The letters show how written personal correspondence served as a road map to recreate the postwar world, and to link the past with the present and reimagine the future while extending elements of camp life into post-camp life.
Taxonomic Revision of the Neotropical Genus Werneria (Compositae, Senecioneae)
Authors: Calvo Joel , Moreira-Muñoz Andrés , Funk Vicki A.
Published: July 2020

Werneria is a neotropical genus belonging to the tribe
Senecioneae (Compositae) that is mainly distributed through the highlands of
the Andes. Only a single species, W. nubigena, has a trans-Andean
distribution and reaches the Tacaná Volcano in southern Chiapas (Mexico). The
traditional concept of Werneria was significantly narrowed at the end of
the twentieth century after segregating several species and accommodating these
mostly in the genus Xenophyllum. As currently circumscribed, it includes
rosettiform or scapiform species characterized by usually displaying involucral
bracts that are fused at the base, supplementary bracts commonly absent,
usually radiate but sometimes discoid or disciform capitula, white or yellow
ray corollas (when present), a balusterform filament collar, and style branches
that are truncate and have a crown of sweeping hairs. The first modern,
comprehensive revision of this genus recognizing 27 species is presented here. Werneria
heteroloba and W. obtusiloba are synonymized with W. pinnatifida,
and W. acerosifolia is synonymized with W. staticifolia.
Moreover, five infraspecific names and three supraspecific names are
synonymized. Detailed descriptions, distribution maps, photographs of living
plants (except for W. cochlearis), and a list of all specimens examined
are provided for each accepted species. An identification key to the species
and a list of exsiccatae are also given. Eight species are illustrated, two of
them for the first time. The following names are lectotypified: Werneria
brachypappa Sch. Bip., W. caespitosa Wedd., W. calyculata Turcz.,
W. canaliculata Sch. Bip., W. carnulosa A. Gray, W. densa Benth.,

Published: July 2020

Technical development and system optimization during the last decades have targeted more efficient, socially acceptable and ecologically sustainable ways to use forestry machines and tools. This is supported by the development of electronics and electrical components, as well as battery technology, without which it is impossible to imagine doing some forestry work in forest areas with no permanent source of electricity. Today, we cannot imagine life without e.g. a cell phone, and also doing business in the forestry sector without a field computer. There are numerous examples in everyday life, but also in industry, where portable devices make life and business much easier, and the basis for the operation of these devices is battery technology. The importance of the development of battery technology is proven by the fact that in 2019 the Nobel Prize in Chemistry went into the hands of scientists who developed a lithium-ion battery - a lightweight, rechargeable and powerful battery that is used today in numerous products from mobile phones to laptops and electric vehicles. This paper will outline the historical development of battery technology and the use of battery powered devices, tools and machines with their advantages and disadvantages in forestry sector.
Study of oxygen evolution reaction on thermally prepared xPtOy-(100-x)IrO2 electrodes
Authors: Kambiré Ollo , Pohan Lemeyonouin A. G. , Kondro Konan H. , Ouattara Lassiné
Published: July 2020

The mixed coupled xPtOy-(100-x)IrO2 electrodes (x = 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 and 100) were thermally prepared at 450 °C on titanium supports. The prepared electrodes were firstly physically characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Afterwards, electrochemical characteri­zations were performed by voltammetric (cyclic and linear) methods in different electrolyte media (KOH and HClO4). It is shown that the prepared electrodes are composed by both PtOy (platinum and platinum oxide) and IrO2 (iridium dioxide). For xPtOy-(100-x)IrO2 electrodes having higher content of IrO2, more surface cracks and pores are formed, defining a higher surface area with more active sites. Higher surface area due to presence of both PtOy and IrO2, is for xPtOy-(100-x)IrO2 electrodes in 1 M KOH solution confirmed by cyclic voltammetry at potentials of the oxide layer region. For all prepared electrodes, voltammetric charges were found higher than for PtOy, while the highest voltammetric charge is observed for the mixed 40PtOy-60IrO2 (x = 40) electrode. The Tafel slopes for oxygen evolution reaction (OER) in either basic (0.1 M KOH) or acid (0.1 M HClO4) media were determined from measured linear voltammograms corrected for the ohmic drop. The values of Tafel slopes for OER at PtOy, 90PtOy-10IrO2 and IrO2 in basic medium are 122, 55 and 40 mV dec-1, respectively. For other mixed electrodes, Tafel slopes of 40 mV dec-1 were obtained. Although proceeding by different OER mechanism, similar values of Tafel slopes were obtained in acid medium, i.e., Tafel slopes of 120, 60 and 39 mV dec-1 were obtained for PtOy, 90PtOy-10IrO2 and IrO2, and 40 mV dec-1 for other mixed electrodes. The analysis of Tafel slope values showed that OER is more rapid on coupled mixed electrodes than on pure PtOy. For mixed xPtOy-(100-x)IrO2 electrodes, OER is more rapid when the molar percent of PtOy meets the following condition: 0 ˂ x ≤ 80. This study also showed that the mixed coupled electrodes are more electro­cata­lytically active for OER than either PtOy or IrO2 in these two media.

Published: July 2020

Criteria for risk assessment are listed in the ordinance of the Minister of Health on harmful biological agents in the workplace and the protection of workers exposed to those agents. Accordingly, risk assessment should be based on all available information including classification of biological agents, risk groups 2-4; information on diseases which may be contracted as a result of work; information on diseases from which workers are found to be suffering and which have a direct connection with their work; recommendations from competent sanitary authorities; National Labour Inspectorate; and occupational medicine services.
Work engagement as a factor reducing the risk of occupational stress – based on original research
Authors: Grobelny Jarosław
Published: July 2020

Occupational stress is the result of a perceived lack of balance between the work environment’s demands and the employee's ability to cope with these demands. According to the stress process model, the employee's resources can moderate the relationship between the job demands and perceived stress. Work engagement, the long-term and positive affective-cognitive state, may constitute such a resource. The results of this study confirm this assumption. In the group of workers less engaged in work, the level of perceived occupational stress was higher than in the group of engaged workers and the level of this attitude significantly moderated the relationship between job demands and perceived stress. Practical implications about organizational factors influencing work engagement are also discussed.

Problems with signal lighting colours’ recognition
Authors: Owczarek Grzegorz
Published: July 2020

The article presents the main eye hazards caused by excessive eye exposure on optical radiation. The human eye sensitivity spectral distribution in the context of signal colour recognition was discussed. In order to explain the effects of the mechanism of phenomena responsible for the recognition of signal lights colour, a graphical analysis of spectral distributions of signal lights emitted from traditional incandescent sources and LED sources (light emitting diode) was performed.
This analysis also takes into account the conditions under which observation of signal lights may take place (daylight and night vision conditions). The conclusions also indicate the further direction of studies on the influence of colour recognition affected by vision conditions, eye sensitivity spectral distribution (including disturbance of colour recognition) and different types of signal light sources.

Accidents in agriculture jobs: the concept
Authors: Chmarycz Aleksandra
Published: July 2020

Agriculture is an industry with a high rate of accidents at work. Issues related to agricultural accidents at work are governed by the Act of 20 December 1990 on farmers' social insurance. Due to the persistently low level of safety on farms, it is very important to correctly define and use the provisions of social insurance against accidents at work. The concept of an accident in agricultural jobs is of primary importance. It is necessary to amend it because its interpretation raises numerous questions and doubts. Examples of case-law and doctrine indicate legal problems, which remain to be solved.

Robust and Adaptive Control for Synchronous Generator’s Operation Improvement
Authors: Ritonja Jožef
Published: July 2020

Synchronous generators produce almost 95% of the world’s electricity. Even a small improvement in their efficiency represents huge savings. Electromechanical oscillations of synchronous generators are harmful—they cause losses and can even lead to instability. An additional control system, called a power system stabilizer (PSS), is used to damp the oscillations of synchronous generators. The commercial realizations of the power system stabilizers are based on the use of the linear control theory. The effectiveness of these power system stabilizers is small, because of the nonlinear and time-varying characteristics of the synchronous generators. The application of robust and adaptive control represents an adequate theoretical basis for ensuring optimal damping of the electromechanical oscillations in a wide operating range. This work reviews the applicability of the advanced control theories to develop power system stabilizers. The work is focused on selecting the appropriate robust and adaptive control theories for the power system stabilizer implementation. The applicability and advantages are presented of the sliding mode control and the direct adaptive control, along with an evaluation of their impact on the operation improvement.

Mesenchymal stem cells (MSCs) are multipotent stem cells that can be isolated from both foetal and adult tissues. Several groups demonstrated that transplantation of MSCs promoted the regeneration of skeletal muscle and ameliorated muscular dystrophy in animal models. Mesenchymal stem cells in skeletal muscle, also known as fibro-adipogenic progenitors (FAPs), are essential for the maintenance of skeletal muscle. Importantly, they contribute to fibrosis and fat accumulation in dystrophic muscle. Therefore, MSCs in muscle are a pharmacological target for the treatment of muscular dystrophies. In this chapter, we briefly update the knowledge on mesenchymal stem/progenitor cells and discuss their therapeutic potential as a regenerative medicine treatment of Duchenne muscular dystrophy.

Simulation of dam breach process has significant influence on the evaluation of consequence of dam breach flood. In this study, research progresses on the numerical modeling of earth-rock dams’ breach process are summarized, especially the latest research results of the author’s research team in recent years. However, there still has a considerable gap in the versatility of computer software and visualization technology of dam breaching process. It is suggested that more efforts should be made in the future to study the detailed physically based numerical model for core dam and concrete face rockfill dam; further, more attention should be paid to the application of visualization technology in dam breach process simulation. Finally, the universal and friendly visualization computer software that can accurately simulate the dam failure process and flood routing for earth-rock dams is sorely needed.
COVID 19 Vertical Transmission: A Growing Concern
Authors: Ghanim Sultan Muhsin , AlAasam Ameer Isam , Alzubaidi Ahmed Athab , Shojaeian Reza
Published: July 2020

Context: COVID 19 vertical transmission is a great concern in different aspects of mother, child, healthcare staff and community safety and protection. There is lack of definitive evidence confirming or declining mother to child COVID 19 transmission. This article is an update on this challenging issue. Evidence Acquisition: This article is a comprehensive search in scientific major database from 1 January 2020 up to 25 April 2020 with the key words of “COVID 19” and “vertical transmission” or “neonatal”. Two researchers reviewed all selected articles to extract data about neonatal COVID 19 and vertical transmission. Those reports that provided the results of PCR on fetus or neonate blood, amniotic fluid or pharyngeal secretion samples or elevated COVID 19 specific IgM were included. Those reports based on clinical COVID 19 characteristics or radiological findings were not included in data extraction. Thirty six articles have been reviewed and evidence supporting or against COVID 19 Vertical transmission have been extracted and discussed. Results: Most previous studies on vertical COVID 19 transmission have been tested placenta, amniotic fluid, cord blood and newborn blood or pharyngeal swab sample using quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) that may show false negative results due to suboptimal sampling or inefficient viral load. Increased COVID 19 specific IgG/IgM antibodies have been reported in newborns from COVID 19 mothers; however, data is limited and longitudinal follow up is needed. Evidence supporting COVID 19 vertical transmission: Recent reports indicated that pharyngeal PCR test turned positive in first few hours of life in several neonates. Also increased level of COVID 19 specific IgM and IgG antibodies in newborns to COVID 19 positive mothers were observed. Rate of perinatal complications were higher among newborns of COVID 19 mothers. Evidence against COVID 19 vertical transmission: All tissue or blood specimens and pharyngeal swab qRT-PCR tests among neonates born from COVID 19 mothers were negative. Rate of cross reactivity and false positive results are high in serologic studies. Conclusions: COVID 19 vertical transmission is a growing health care concern that needs further investigation; however, it is suggested to be equipped with PPE on contacts with both COVID 19 pregnant woman and her newborn baby and apply early separation, isolation, testing and close follow up for both mother and child.

Authors: Song Myung Gyu , Seo Tae-Seok , Yang Woo Jin
Published: July 2020

Background: The incidence of venous thrombosis based on access route after implantation of the totally implanted venous access port (TIVAP) is controversial. Symptomatic TIVAP-related venous thrombosis remains relatively rare. However, characteristics of symptomatic axillary vein thrombosis after TIVAP implantation via access of the axillary vein has not been reported. Objectives: In this historical cohort study, the incidence and characteristics of venous thrombosis associated with TIVAP via the axillary vein in cancer patients were evaluated. Patients and Methods: A total of 4,773 TIVAPs were placed via the axillary vein in patients with various types of cancer between May 2012 and July 2018. Eighteen patients experienced symptomatic venous thrombosis associated with TIVAPs. Radiologic findings for venous thrombosis were evaluated using computed tomography (CT) including scans of the axillary vein. Medical records were retrospectively reviewed. Results: The prevalence of symptomatic thrombosis was 0.38% (18/4,773). The patients with symptomatic venous thrombosis included 14 males and four females. Among the 18 patients, the most common types of cancer were lung cancer (n = 7) and pancreatic cancer (n = 4), with the incidence rates of 0.79% (lung cancer, 7/882) and 1.58% (pancreatic cancer, 4/253), respectively. The median time between placement of the TIVAP and diagnosis of thrombosis was 35.5 days (range: 6 - 292 days). All symptomatic patients had thrombosis in the axillary vein on CT images. Symptoms were improved in all patients with treatment including removal of TIVAP at the time of diagnosis and following anticoagulation therapy. From the multiple binary logistic regression, pancreatic cancer and lung cancer were statistically significant risk factors of symptomatic axillary vein thrombosis. Conclusion: After insertion of TIVAPs through the axillary vein, symptomatic axillary vein thrombosis rarely developed. Pancreatic cancer and lung cancer were associated with the risk of symptomatic axillary vein thrombosis.

O objetivo deste trabalho foi obter uma visão geral das empresas produtoras de pellets provenientes de biomassa residual florestal de Santa Catarina, abordando características relacionadas à matéria-prima, aos equipamentos utilizados, custos de produção, entre outros atributos que influenciam na dinâmica do setor do estado. Foi realizada a aplicação de questionários in loco para cada empresa participante do estudo. As empresas avaliadas iniciaram suas atividades recentemente, a matéria-prima é a maravalha de Pinus spp. com umidade entre 8 e 10% e os equipamentos para peletização são adaptados para biomassa, prejudicando o processo. O mercado interno absorve toda a produção e foi destacado que a criação de uma normatização brasileira seria positiva, principalmente no que diz respeito às classes de qualidade dos pellets. Também foi observada a falta de interação entre as três empresas produtoras de pellets, o que prejudica o crescimento da cadeia produtiva de pellets em Santa Catarina.

Rigor científico en películas recientes de catástrofes. Validación de materiales para el profesorado de geología
Authors: Sanmartín Patricia , Sacedón María , Sanjurjo-Sánchez Jorge
Published: July 2020

Estudios previos demuestran que el uso de películas en el aula incrementa la retención de información, aunque su falta de rigor científico debe ser evaluada, evitando integrar errores en la base de conocimiento del alumnado. Películas de los últimos siete años muestran acertadas reconstrucciones de tsunamis pero incluyen errores sobre las áreas de bordes de placa y en la reconstrucción de procesos geológicos. Para este trabajo se prepararon fichas didácticas con escenas de corta duración de tres películas: La Ola (2015), París: infierno helado (2013) y San Andrés (2015). Todas ellas vertebradas en competencias de geología que se repiten en ESO y bachillerato, como son la tectónica de placas y los minerales y rocas, a la vez que relacionadas con otros contenidos del currículo en esos niveles. El objetivo del trabajo fue hacer un análisis científico de los fragmentos seleccionados y una ficha didáctica de cada uno, que presentara actividades adecuadas a los cuatro niveles, 3° y 4° de ESO y 1° y 2° de BAC, donde la geología es materia de estudio en secundaria.

El artículo analiza las percepciones de los estudiantes de Educación Secundaria Obligatoria (ESO) y Bachillerato sobre el uso de las Tecnologías de la Información y la Comunicación (TIC) en la enseñanza de la historia. La muestra participante fue de 467 estudiantes de Institutos de Educación Secundaria de la Región de Murcia. Este estudio forma parte de un proyecto de investigación de mayor envergadura, relativo a enseñanza de la historia e implantación de metodologías y recursos innovadores. Del cuestionario estructurado para la recogida de información, se han seleccionado los ítems relativos al uso de las TIC y a la visión de los discentes. Los resultados arrojan una persistencia del modelo tradicional de enseñanza, que no prioriza metodologías cooperativas y de indagación, en el cual las TIC siguen teniendo un papel subsidiario. Se conciben como un complemento, más esporádico aún en Bachillerato que en ESO. Las conclusiones determinan que mientras se siga enseñando historia con una visión factual y memorística es difícil formar ciudadanos críticos, con destrezas a la hora de construir su propio aprendizaje. Aunque el alumnado sea nativo digital será difícil que usen los recursos digitales para adquirir habilidades o valores, pues sigue priorizándose la transmisión pasiva de discursos cerrados.

The article analyzes the perceptions of students of Compulsory Secondary Education (ESO) and Baccalaureate about the use of Information and Communication Technologies (ICTs) in the teaching of history. The sample used was 467 students from public High Schools of the Region of Murcia and was part of a larger research, related to the teaching of history and the implementation of innovative methodologies and resources. The items related to the use of ICTs and their vision among students have been selected. The results show a persistence of the traditional teaching model, which does not prioritize cooperative and inquiry methodologies, in which ICTs continue to have a subsidiary role. They are a complement, more sporadic even in Baccalaureate than in ESO. While continuing to teach history with a factual and memorial vision, it is difficult to train critical citizens, with skills when it comes to building their own learning. Even if they are digital natives, it will be difficult for them to use digital resources to acquire skills or values, since passive transmission of closed speeches continues to be prioritized.

Building ground for flexible use of educational technology
Authors: Kenttälä Veera , Kankaanranta Marja
Published: July 2020

Technology has been available for use in schools for several decades. Nevertheless many schools and teachers are still pondering issues related to integration of Information and Communication Technology (ICT) into education. While ICT is used in classroom education, integration of technology
into teaching and learning has not yet been achieved. This study analyzes the barriers to educational technology use and what measures are taken to overcome them. Digitalisation is not merely a question of providing equipment, but rather a change in ways of thinking and learning, and the support
offered to teachers should take this into consideration.
Can Total Joint Arthroplasty Be Safely Performed in Patients with Chronic Kidney Disease?
Authors: Sun Kai , Fan Meng , Jaing Wenxue
Published: July 2020

Background

Patients suffering from chronic kidney disease are at greater risk of perioperative and postoperative complications. There is no systematic review study demonstrating whether total joint arthroplasty can be safely performed in patients with chronic kidney disease.

Methods

A literature search was performed in the PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and Cochrane Library databases for information from the earliest date of data collection to September of 2018. Studies comparing the perioperative and postoperative outcomes of no–chronic kidney dysfunction (CKD) patients with those of CKD patients were included. Statistical heterogeneity was quantitatively evaluated by means of the χ2 test, with significance set at P < .10 or I2 > 50%.

Results

Three articles consisting of 38,209 patients were included (35,363 no-CKD patients and 2,846 CKD patients). The results showed that CKD was related to a greater increase in postoperative infection rate, deep vein thrombosis, readmission, and mortality (P < .1). No differences in length of surgery, length of stay, pulmonary embolism, or revision were observed (P > .10).

Conclusions

Compared with no-CKD patients, CKD patients demonstrated an increased risk of perioperative and postoperative complications.
