Evaluation Indicators of Green Economic Development: The Case of the Baltic Countries
Authors: Alekna Rokas , Kazlauskienė Eglė
Published: July 2020

Research purpose. The green economy may become a solution to the existing problems. The European Union must implement solutions related to the green economy in order to solve the existing ecological, economic and social problems in the region, such as pollution in the Baltic Sea region, inequality, greenhouse gas emissions, climate change and so on. It can be assumed that green economy evaluation research conducted in the scientific community does not always reflect the real situation, due to the lack of indicators or limited evaluation methodology. The aim of this article is characterized by academic literature to identify green economic development indicators and evaluate green economic development indices in three Baltic countries: Lithuania, Latvia and Estonia.

Design/Methodology/Approach. The article uses analysis of scientific literature, systematization, comparative analysis, generalization and data normalization methods.

Findings. The analysed scientific literature and reports of international organizations, resolutions and conference agreements allow to compile a list of indicators for the evaluation of green economy development. The results showed that in all the analysed countries, a strong growth of green economy development indices can be seen; in Estonia, they remained the best among the three Baltic countries during the analysed period. An analysis of which individual indicators are most important in the development of the green economy and have the greatest significance for the index has shown that their estimates and position have changed significantly in less than two decades.

Originality/Value/Practical implications. The identification of green economy indicators provides a new approach to the structure of green economy components. Indicators measured over time describe the structural characteristics and quantitative changes of the green economy, and provides a new understanding of the opportunities and directions of green economy development. In the framework of this study, fifteen indicators were selected for the analysis of green economy in the Baltic States. The normalization and further evaluation of these indicators from the point of view of the green economy allowed to determine the significance of individual social, economic and environmental dimensions for the overall green economy index and to show the changes over a period. The collected data also form the basis for further in-depth prognostic studies.

Published: July 2020

Introduction: Graves’ disease (GD), an autoimmune disorder caused by high levels of auto-antibodies against the thyroid-stimulating hormone receptor, is considered the most common cause of thyrotoxicosis, characterized by features such as goiter, ophthalmopathy and dermopathy. In our country, the administration of antithyroid drugs (ATD) is the first line of treatment in this disease. Side effects are rare but some of them, such as agranulocytosis or liver damage, may become serious.

Case presentation: We report the case of a 20-year-old female patient who was diagnosed with GD after being previously diagnosed with viral hepatitis A. Treatment was initiated with methimazole 30 mg/day, and three weeks later she developed intense hepatic cytolysis and cholestatic syndrome, therefore the ATD was stopped. A suspicion of autoimmune liver disease was raised, and a liver biopsy was performed in order to establish the diagnosis. The next therapeutic option for hyperthyroidism was radioactive iodine (RAI). Three months following RAI, the patient presented severe hypothyroidism, thereupon treatment with levothyroxine was initiated.

Conclusions: Although severe acute liver injury is rare, mild liver dysfunction is quite common in patients with GD. The overproduction of thyroid hormones, or the treatment with ATD through immune mediated processes or drug reactions, represent possible mechanisms responsible for liver damage.

Background: Breast cancer is the female cancer with the highest mortality. While early detection is a public health priority in Western European countries, a screening program in our country has yet to be implemented. The best diagnostic accuracy is achieved through the use of triple assessment: clinical examination, imaging, and core-needle biopsy where indicated. Prognosis is influenced by clinical, histological, and biological factors, and therapy is most effective when individually tailored.

Aim of the study: To analyze the clinical, histological, and immunohistochemical characteristics of the biopsied nodules and summarize our experience from the last three years.

Material and Methods: We retrospectively analyzed data from 137 patients who underwent core-needle biopsy between 2017 and 2019. Imaging score was assigned based on ultrasound examination or mammography. Clinical and pathological parameters were recorded, followed by statistical processing of the data.

Results: The mean age of the patients was 58 ± 14 years, lesions had a mean size of 22.83 ± 14.10 mm. Most nodules (n = 63, 47.01%) were located in the upper-outer quadrant, and bilateral presence was found in 4 (3.08%) cases. We found a significant positive correlation between lesion size and the patients’ age (Spearman r = 0.356; 95% CI 0.186, 0.506; p = 0.000). The malignancy rates within the Breast Imaging Reporting and Data System (BI-RADS) categories were as follows: 0% for „4a”, 31.58% for „4b”, 71.42% for „4c”, and 97.72% for „5”. Most malignancies (n = 73, 78.35%) were represented by invasive ductal carcinoma of no special type, 58.43% (n = 52) were grade 2, 89.13% (n = 82) were estrogen receptor positive, and Luminal B-like type was the most common (n = 63, 78.75%).

Conclusions: The mean size of tumors was larger than the average size at discovery described in the literature. In our region, age and tumor size are positively correlated. Preoperative histological results may indicate the reliability of the imaging risk stratification system. Most cases can benefit from adjuvant endocrine therapy.

Published: July 2020

On March 11, 2020, the WHO declared that coronavirus disease 2019 (COVID-19) can be characterized as a pandemic based on the alarming levels of spread and severity and on the alarming levels of inaction. COVID-19 has received worldwide attention as emergency, endangering international public health and economic development. There is a growing body of literatures regarding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as well as COVID-19. This review will focus on the latest advance of epidemiology, pathogenesis, and clinical characteristics about COVID-19. Meanwhile, tuberculosis (TB) remains the leading representative respiratory tract communicable disease threatening public health. There are limited data on the risk of severe disease or outcomes in patients with concurrence of TB and COVID-19. Nevertheless, co-infection of some virus would aggravate TB, such as measles. And tuberculosis and influenza co-infection compared with tuberculosis single infection was associated with increased risk of death in individuals. This review will also introduce the characteristics about the concurrence of TB and emerging infectious diseases to provide a hint to manage current epidemic.

Published: July 2020

Introduction

The objective of this research was to evaluate the antibody response to multiple doses of an inactivated mixed vaccine against Histophilus somni, Pasteurella multocida, and Mannheimia haemolytica, and to investigate the influence of age at time of vaccination in the field.

Material and Methods

Healthy female Holstein calves received the vaccine at the age of 5–12 days and 2, 3, or 4 weeks later in the first experiment or at 1, 2, or 3 weeks of age and 4 weeks later in the second. Blood samples were collected at each vaccination and 3 weeks after the booster dose. Based on the antibody titres after the vaccinations, calves were divided into positive and negative groups for each of the bacteria. Calves in the control group were vaccinated only once at the age of 19–26 days.

Results

Antibody titres against H. somni and P. multocida were significantly increased by the booster. After the second vaccinations, the titres against each bacterium were higher than those of the control group, and the M. haemolytica-positive percentage in calves with high maternal antibody levels (MAL) exceeded that in calves with low MAL. In the first experiment, a majority of the M. haemolytica-positive calves tended to have received the primary dose at seven days of age or older.

Conclusion

A booster dose of the inactivated bacterial vaccine in young Holstein calves increased antibody production and overcame the maternal antibodies. Calves should be vaccinated first at seven days of age or older.

A field experiment was carried out to investigate the effect of different manures and fertilizers on the growth and yield of knol-khol (Brassica oleracea var. gongylodes) at Dr. Purnendu Gain Field Laboratory of Agrotechnology Discipline, Khulna University, Khulna from November 2014 to February 2015. The single factor experiment comprised of different types of fertilizers and manures viz., T0 (Control), T1 (Recommended doses of NPK), T2 (Cow dung), T3 (Vermicompost), T4 (Poultry manure), T5 (50 % Cow dung + 50 % NPK), T6 (50% Vermicompost + 50% Cow dung), T7 (50% Vermicompost + 50 % Poultry manure) and T8 (25% Cow dung+ 25% Vermicompost+ 25% Poultry manure + 25% NPK). The Experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. The maximum plant height was obtained from the treatment T1 at 25, 35 and 45 Days after transplanting (DAT). The maximum spread of canopy was 36.75 cm, 52.50 cm and 66.05 cm from the treatment T3, T7 and T2, respectively. The maximum economic yield (21.92 t/ha) and biological yield (40.083 t/ha) were found in the treatment T1 and T7, respectively. Highest benefit cost ratio (3.07) was obtained from the treatment T1whilethe minimum (0.57) was obtained from T3 which indicates that high cost of vermicompost affect net return severely. Although, T1 produced maximum benefit cost ratio, the treatment T4 and T2 are very close to T1 and also statistically similar. So, we can consider poultry manure and cow dung for our soil health, environmental benefits and ecological safety.

Authors: Lalou Panagiota , Ponis Stavros T. , Efthymiou Orestis K.
Published: July 2020

Forecasting the demand of network of retail sales is a rather challenging task, especially nowadays where integration of online and physical store orders creates an abundance of data that has to be efficiently stored, analyzed, understood and finally, become ready to be acted upon in a very short time frame. The challenge becomes even bigger for added-value third party logistics (3PL) operators, since in most cases and demand forecasting aside, they are also responsible for receiving, storing and breaking inbound quantities from suppliers, consolidating and picking retail orders and finally plan and organize shipments on a daily basis. This paper argues that data analytics can play a critical role in contemporary logistics and especially in demand data management and forecasting of retail distribution networks. The main objective of the research presented in this paper is to showcase how data analytics can support the 3PL decision making process on replenishing the network stores, thus improving inventory management in both Distribution Centre (DC) and retail outlet levels and the workload planning of human resources and DC automations. To do so, this paper presents the case of a Greek 3PL provider fulfilling physical store and online orders on behalf of a large sporting goods importer operating a network of 129 stores in five different countries. The authors utilize the power of ‘R’, a statistical programming language, which is well-equipped with a multitude of libraries for this purpose, to compare demand forecasting methods and identify the one producing the smallest forecast error.

Authors: Vrânceanu Diana-Maria , Țuclea Claudia-Elena , Țigu Gabriela
Published: July 2020

Price represents a source of information customers may rely on in the buying decision making process. The literature in this area shows that on the Internet, the process of searching for price information is more complex than on traditional stores, being influenced by various factors. This paper aims to identify and describe the relations between two categories of variables. On the one hand there are the variables related to the price searching behaviour on the online environment, and on the other hand there are the variables related to the buying process. This research is based on a survey, the sample consisting of 1112 online buyers. The relationships between these variables were represented through a conceptual model based on a structural equation modeling approach. The main findings of the research show that the more a customer searches for price information online, the more he/she acquires abilities to search, becoming more predisposed to perceive a better value from shopping online and intending more to purchase from the Internet. The managerial implications concern the communication strategies adopted by online stores, the information provided by them influencing the perceived value of doing online shopping and the buying intentions on the Internet.

Authors: Purwanto Edi , Deviny July , Mutahar Ahmed M.
Published: July 2020

Millennials have a lifestyle that is different from previous generations. Millennial Generation lives and grows together with rapid technological growth and currently dominates the population in Indonesia. The purpose of this study is to empirically determine the factors that influence the millennial generation’s loyalty to mobile banking applications. Elements used to analyze the millennial generation’s loyalty are corporate image, application security, word of mouth (WoM), and trust. Data collected through questionnaires from a sample of 395mobile banking users in Indonesia. The study uses structural equation modeling (SEM) to test the hypotheses with Amos 24 as the analysis tool. The results of the study proved that all predictions are proven significant. The trust in mobile banking mediates the effects of corporate image, application security, and word of mouth on millennial’s loyalty. The respondent of the research was millennial mobile banking users in Indonesia. Therefore, the model should be replicated among other mobile banking users in other countries. Banks have to maintain an excellent corporate image and get a positive transmission because, in this digitalization era, information can spread very quickly between friends, relatives, family, or through the internet, digital media, and social media. Banking also needs to include a guaranteed level of application security in the mobile banking application provided to gain the trust of users and be able to foster and increase their loyalty. However, there are still other factors that can influence millennial’s loyalty to a mobile banking application.

Published: July 2020

This paper aims at investigating the relationship between knowledge sharing activities and innovation capability at both individual and organizational levels. By reviewing extensive literature, a conceptual framework is built with integrating three factors: knowledge sharing, individual innovation capability and firm innovation capability. This study applies structural equation modeling (SEM) to analyze the data collected from 392 employees working at major Vietnam’s telecommunication companies. Empirical results show that knowledge sharing including knowledge donating, knowledge collecting play an important role in improving individual innovation capability. There is no direct link between knowledge collecting and organizational innovation capability, while knowledge donating has direct positive impact on product and managerial innovation. Furthermore, the individual innovation capability acts as a mediating variable between knowledge sharing practices and firm innovation capability. Implications for academics and practitioners are provided in this study.

Published: July 2020

According to the new European Union Basic Safety Standards (EU-BSS), preparation of the National Radon Action Plan is obligatory for the Member States. One of the plan’s aims is to carry out an indoor radon survey to identify radon-prone areas. In the radon surveys, track detector methods are used. At the University of Pannonia (Veszprém, Hungary), a new scanner-based detector evaluation system has been developed. For the application of the new system, the selection of appropriate parameters is necessary. In this study, selection of the applied track detectors and setting of the etching conditions have been carried out. Two different types of allyl diglycol carbonate (ADC or CR-39) track detectors were investigated, taking into account the detector’s background and response during the exposure (determination of calibration factor). The Baryotrak’s background track density (0–1.5 tracks mm−2) was lower than that of the 0.8–4 tracks mm−2. The response of the Tastrak was higher, but the deviation of the calibration factor was much higher (1.2–5.3 × 10−3 tracks mm−2/(Bq day m−3)) than in the case of the Baryotrak (1.4–2.8 × 10−3 tracks mm−2/(Bq day m−3)). After the systematic review of the etching system, a new method was developed. For the determination of the optimal track diameter, the argon fluoride (ArF) laser was applied to create tracks with diameters in the range of 10–100 μm. The optimum track size was in the range of 40–60 μm. On this basis, new etching conditions were determined: 6.25 M NaOH solution, a temperature of 90°C, and time period of 8 hours.
Coach or sensei? His group relations in the context of tradition
Authors: Cynarski Wojciech J.
Published: July 2020

In the perspective of the General Theory of Fighting Arts, an analysis of socio-cultural factors that determine the opposition of the role of a teacher of martial arts (Jap. sensei) to the role of a sports trainers was undertaken. The structural cultural context, cultural patterns, and social institutions resulting from divergent goals were taken into account. The roles of teachers and trainers result from these conditions. The existence of the separate roles of the master-teacher in martial arts and the sports trainer was established. These roles manifest themselves in different relations with students or players. Democratic and egalitarian interactions in sports teams include player and coach relations. In traditional martial arts, the dominance of the teacher is more accepted. However, there is also a social position combining the features of the sensei and the trainer that is typical for combat sports that are also martial arts (participating in sports competitions). As there are relationships of subordination in the hierarchical societies of Japan and Korea, there is no problem with recognizing the primary role of the sensei in these cultures. The position of the master-teacher is also sanctified by tradition. Reducing educational systems, which are the paths of martial arts, to oriental varieties of sports would be a serious factual mistake.

Published: July 2020

The purpose of the study was to analyze single fraction Gamma Knife stereotactic radiosurgery (SRS) for uveal melanoma (UM). In the treatment of UMs, the dose distribution exhibited by an irregular eye surface has more calculation uncertainty. A tissue-equivalent bolus was placed on the left eye surface of a human head-shaped phantom. It was assumed that the treated eye is fixed using retrobulbar anesthesia and suture on extraocular muscles for phantom study. Leksell stereotactic frame was fixed around phantom’s head and the stereotactic computed tomography (CT) was performed. Two sets of scans were acquired (a) without bolus and (b) with a bolus of 1.0 cm thickness. These scans were transferred into a treatment planning system (TPS). The skull contouring was performed using stereotactic CT images. The target, visual pathways, and eye lens were delineated in stereotactic CT space created on TPS. A clinical relevant plan was designed on the CT study set “a” to deliver a radiation dose of 30Gy at tumor margin. The plan superimposed over CT study set “b” and compiled for convincing treatment strategy. The tumor coverage was 95% at 50% prescription isodose line. The conformity index, selectivity and the gradient index were 1.27, 0.80 and 3.28 respectively. The left optic nerve and eye lens received a maximum dose of 11.1 Gy and 11.0 Gy respectively. The treatment plan overlay showed similar planning indices and critical organ doses. The plan comparison showed: an irradiated volume received the radiation dose > 15 Gy varies < 1.0% whereas the volume received < 15 Gy were larger (> 1.0%) in the study set “b”. The distant lateral points from the target volume which describe the phantom’s eyelid showed a radiation dose of 3.2 Gy - 2.5 Gy. The doses to these points were misled and ignored in the CT study set “a”. The eye bolus provides better dosimetric information in the estimation of low dose areas which is commonly misled on TPS in SRS planning for UMs.
Simplified perfusion fraction from diffusion-weighted imaging in preoperative prediction of IDH1 mutation in WHO grade II–III gliomas: comparison with dynamic contrast-enhanced and intravoxel incoherent motion MRI
Authors: Wang Xiaoqing , Cao Mengqiu , Chen Hongjin , Ge Jianwei , Suo Shiteng , Zhou Yan
Published: July 2020

Background

Effect of isocitr ate dehydrogenase 1 (IDH1) mutation in neovascularization might be linked with tissue perfusion in gliomas. At present, the need of injection of contrast agent and the increasing scanning time limit the application of perfusion techniques. We used a simplified intravoxel incoherent motion (IVIM)-derived perfusion fraction (SPF) calculated from diffusion-weighted imaging (DWI) using only three b-values to quantitatively assess IDH1-linked tissue perfusion changes in WHO grade II-III gliomas (LGGs). Additionally, by comparing accuracy with dynamic contrast-enhanced (DCE) and full IVIM MRI, we tried to find the optimal imaging markers to predict IDH1 mutation status.

Patients and methods

Thirty patients were prospectively examined using DCE and multi-b-value DWI. All parameters were compared between the IDH1 mutant and wild-type LGGs using the Mann–Whitney U test, including the DCE MRI-derived K
trans, v
e and v
p, the conventional apparen t diffusion coefficient (ADC
0,1000), IVIM-de rived perfusion fraction (f), diffusion coefficient (D) and pseudo-diffusion coefficient (D*), SPF. We evaluated the diagnostic performance by receive r operating characteristic (ROC) analysis.

Results

Significant differences were detected between WHO grade II-III gliomas for all perfusion and diffusion parameters (P < 0.05). When compared to IDH1 mutant LGGs, IDH1 wild-type LGGs exhibited significantly higher perfusion metrics (P < 0.05) and lower diffusion metrics (P < 0.05). Among all parameters, SPF showed a higher diagnostic performance (area under the curve 0.861), with 94.4% sensitivity and 75% specificity.

Conclusions

DWI, DCE and IVIM MRI may noninvasively help discriminate IDH1 mutation statuses in LGGs. Specifically, simplified DWI-derived SPF showed a superior diagnostic performance.

Authors: Almasarweh Sa’ed , Sudah Mazen , Joukainen Sarianna , Okuma Hidemi , Vanninen Ritva , Masarwah Amro
Published: July 2020

Background

Breast hematoma is an often underrated and disregarded post-procedural complication in the literature. Current treatment modalities are comprised of either surgical or expectant therapy, while percutaneous procedures play a smaller role in their treatment. We aimed to examine the efficacy of vacuum-assisted evacuation (VAE) in the treatment of clinically significant large breast hematomas as an alternative to surgery.

Patients and methods

We retrospectively analysed patients that underwent breast interventions (surgical and percutaneous), who later developed clinically significant large hematomas and underwent a trial of VAE of hematoma in our hospital within the period of four years. Patient and procedure characteristics were acquired before and after VAE. Success of intervention was based on ≥ 50% clearance of hematoma volume and patients’ subjective resolution of symptoms. All patients were followed clinically and by ultrasound if needed at different intervals depending on the severity of presenting symptoms.

Results

Eleven patients were included in the study. The mean largest diameter of hematomas was 7.9 cm and mean surface area was 32.4 cm2. The mean duration of the procedure was 40.5 min. In all patients VAE of hematoma was implemented successfully with no complications. Control visits showed no major residual hematoma or seroma formation.

Conclusions

Our results show that VAE of hematoma can be implemented as a safe alternative to surgery in large, clinically significant hematomas, regardless of aetiology or duration. The procedure carries less risk, stress and cost with the added benefit of outpatient treatment when compared to surgical treatment.

Authors: Layade Gideon , Ogunkoya Charles , Makinde Victor , Ajayi Kehinde
Published: July 2020

The article presents the grain size distribution of soil samples from the Precambrian basement within the purview of the textural properties, deduced transportation history and the numerical assessments using statistical parameters. The fourteen soil samples collected from the study area were subjected to sieve analysis in the laboratory for the determination of their grain size distribution. The statistical parameters’ study includes the graphic mean, skewness, sorting and kurtosis. The result of the analysis of the soil samples ranged from coarse to fine-grained samples, moderately and poorly sorted, positively and negatively skewed and the kurtosis also shows leptokurtic as the most dominant which suggests the samples poorly distributed and moderately sorted at the centre of the grain size distribution. These results also suggest the geological environment of the soil samples could be responsible for the poorly and moderately sorted exhibited by the samples deposited in the location.
Engineering Site Investigation and Shallow Foundation Design in Ore Area of Ondo State, Nigeria
Authors: Olumuyiwa O. Falowo
Published: July 2020

The study integrates geophysical and geotechnical methods for subsoil evaluation and shallow foundation design. The study involved six vertical electrical sounding and geotechnical investigation involving cone penetration test and laboratory soil analysis. Three major geologic units were delineated; the topsoil, weathered layer and partly weathered/fractured/fresh bedrock. The overburden thickness is in between 15.2–32.9 m. Based on resistivity (16–890 ohm-m) and thickness (12.7–32 m) the weathered layer is competent to distribute structural load to underlying soil/rock. The groundwater level varies from 4.5 to 12.3 m. Therefore an average allowable bearing capacity of 200 kPa is recommended and would be appropriate for design of shallow foundation in the area, at a depth not less than 1.0 m with an expected settlement ranging from 9.03–48.20 mm. The ultimate bearing and allowable bearing capacity for depth levels of 1–3 m vary from 1403–2666 kPa and 468–889 kPa for strip footing while square footing varies in between 1956–3489 kPa and 652–1163 kPa respectively.

Published: July 2020

The wood waste conversion processes in a dry distillation chamber with an executive body based on a multifunctional electromechanical converter were analysed. It was established that under the influence of a low-frequency magnetic field, the properties of moisture evaporating from biomass change, and the evaporation heat decreases. A method for generating negatively charged molecular complexes in the form of water vapour by heating biomass, exposure to the electric and magnetic field, followed by the injection of negatively charged hydroxide ions of water vapour into a solid carbon product at the final stage of the pyrolysis process is proposed. The possibilities of heat recovery of the screw energy technological complex for preheating biomass in a loading device using the thermal energy of the spent heat carrier, the energy dissipative component of the installation’s electromechanical part and the thermal energy utilisation of the produced solid products have been estimated.

The article is devoted to an analysis of accidents involving pedestrians in traffic. An analysis of the statistical data of accidents involving pedestrians in the Republic of Belarus has been made. The main patterns and trends of accidents involving pedestrians are identified. A detailed analysis of the accident rate at pedestrian crossings and intersections was carried out, which made it possible to establish the most dangerous types of collisions during the interaction of transport and pedestrian flows. Experimental studies of collision situations were also carried out, which made it possible to establish the dependence of the violation rate on the composition of the right-handed traffic flow, on the type of traffic signal that regulates traffic on the right, as well as on the size of groups of pedestrians in front of cars.
Monitoring Changes in the Morphology and Storage of a Small Water Reservoir: A Case Study from Vrbovce, Slovakia
Authors: Výleta Roman , Valent Peter , Danáčová Zuzana
Published: July 2020

One of the most profound problems in the operation of water reservoirs is their siltation by sediments coming from agricultural land. The siltation of water reservoirs can significantly shorten their life spans and prevent them from effectively fulfilling their functions. Therefore, accurate monitoring of the current state and dynamics of siltation processes is critical to maintaining their economic, environmental, and societal functions. This study presents a simple method to evaluate the sedimentation rate of a small water reservoir in Slovakia. The method is based on comparing the results from two bathymetric surveys that were carried out in 2017 and 2019 using an ultrasonic acoustic doppler current profiler (ADCP), which was originally developed to measure river discharges. A raster map of the thickness of the sediment in the reservoir was assembled by subtracting the two bathymetric surveys from each other. The analysis of the results showed that the mean annual sedimentation rate of the reservoir is only 101 m3/year, representing a mean increment in sediment thickness of 1.4 cm. The method described showed promising results and could be applied to numerous small water reservoirs of a similar size across Slovakia.

Authors: Vo Thanh Sang , Le Phuong Uyen , Ngo Dai-Hung
Published: July 2020

The purpose of this study is to investigate in vitro hypoglycemic and free radical scavenging activities of some medicinal plants including Ficus glomerata (FG), Pandanus amaryllifolia (PaA), Artocarpus altilis (AA), Gomphrena celosioides (GC) and Gynostemma pentaphyllum (GP). Alpha-amylase inhibitory assay was examined by dinitrosalicylic acid reaction. Glucose uptake assay was investigated by LO-2 cell model. DPPH and ABTS+ scavenging assays were performed by spectrophotometry. Cell viability was determined by MTT method. It was found that the extracts including FG, PaA, AA, GC and GP were able to inhibit alphaamylase activity up to 38.4 ± 4.2%, 47.8 ± 4.3%, 49.3 ± 3.5%, 40.1 ± 4.4% and 38.5 ± 3.8%, respectively. Moreover, glucose adsorption and glucose uptake capacity of these extracts were evidenced. In addition, free radical scavenging activity of these extracts was indicated in a range of 30.6-54.5% for DPPH radical and 31.8-51.1% for ABTS+ radical. Especially, these extracts exhibited no cytotoxicity effect on human hepatic LO-2 cells and human gastric BGC-823 cells at the concentration of 100 μg/ml. The results indicated that A. altilis leaves were effective in inhibiting alpha-amylase activity, increasing glucose adsorption and glucose uptake and scavenging free radicals. Therefore, it could be suggested to be a promising hypoglycemic agent for managing type 2 diabetes.
Fear of Relationship Loss: Attachment Style as a Vulnerability Factor in Job Burnout
Authors: Pšeničny Andreja , Perat Mitja
Published: July 2020

Objective

To investigate the correlation between attachment styles and various burnout risk groups (“relaxed”, “wornout”, “challenged” and “burnout”) and whether attachment styles suitably discriminate between individual burnout risk groups.

Method

The study involved 2,320 participants (1,668 women and 652 men), who completed an adrenal burnout syndrome questionnaire, a performance-based self esteem scale, a work addiction risk test and a relationship questionnaire.

Results

A one-way analysis of variance confirmed attachment style differences between burnout risk groups. The challenged and burnout groups differed from the relaxed and wornout groups by having a significantly lower secure attachment style score and a higher insecure (avoidant and preoccupied) attachment style score. The canonical discriminant analysis showed that the predictors (secure, preoccupied and avoidant attachment styles) can be used to appropriately classify 85.4% of respondents in the predicted burnout risk groups.

Conclusion

The study confirmed the hypothesis that two insecure attachment styles (i.e. avoidant and preoccupied) predominate in the challenged and burnout groups, and that a secure attachment style predominates in the relaxed and wornout groups. Burnout syndrome can thus be conceived as the result of excessive and compulsive efforts to retain a relationship that is perceived as insecure or to reduce (excessive) fear of losing this relationship.
Injury Occurrence in Modern and Hip-Hop Dancers: A Systematic Literature Review
Authors: Uršej Eva , Zaletel Petra
Published: July 2020

Introduction

Dance-related injuries have become a field of great interest to researchers, with the most commonly reported injuries being those sustained by ballet dancers. However, there is a lack of research into injuries sustained by those who perform modern and hip-hop dance.

Methods

A systematic literature review using the MEDLINE research database was performed and a search carried out for full-text studies that investigate injuries in modern and hip-hop dance.

Results

While a total of 74 hits were obtained from various searches, only nine studies were included in the systematic literature review. Six of them examined modern dancers, two examined break dancers and one examined hip-hop dancers. The results show that hip-hop dancers (and especially break dancers) sustain more injuries in comparison to modern dancers. The most common injuries are in the lower extremities, with studies revealing that overuse injuries occur in up to 71% of cases.

Conclusions

The injury incidence rate in hip-hop dance seems to be higher compared to modern dance, chiefly because of the more demanding biomechanics involved and the dance techniques employed. Prevention management can have a positive effect on the number of injuries.

In today’s economy, which is extremely challenging and competitive at the same time, many people want to have their own business and manage their own incomes. Entrepreneurship is a key driver of today’s economy. This observation underscores the need to ensure adequate entrepreneurial education, in line with the demands on the labor market. The purpose and role of this experience are to educate students to understand the entrepreneurial activity, to develop their entrepreneurial skills and competencies and the intention to run a business. The learning environment is crucial for a successful entrepreneur and he can generate change. This article describes experiences from developing and using the entrepreneurial learning environment in high schools with a technological profile. In this study 1200 students from three technological high schools were observed, the behavior and the results obtained after studying the specialized economic modules were analyzed. Our goal was to identify the main challenges of these students. In our study, we used a mixed-method: questionnaires, topic-based interviews, direct and participatory observation as data collection methods. According to our results, the main challenges were: difficulties in understanding new entrepreneurial notions due to traditional teaching methods, lack of ICT skills, lack of team learning principles and inefficient communication within a group.

Nutritional support for patients with chronic kidney disease at pre-dialysis stages
Authors: Kuzmina Alexandra V.
Published: July 2020

Chronic kidney disease (CKD) is characterized by poor outcomes, an increasing frequency of new cases, the need for expensive method of renal replacement therapy at the terminal stage. The main task facing the doctor is slowing the progression of CKD and delay the start of dialysis by applying the nephroprotective strategy, of which diet therapy is an essential part. The key components of the diet for CKD patients are reducing sodium intake to 2.3 g per day in order to improve control of blood pressure (BP), dietary protein restriction adequate to renal function from 0.8 to 0.3 g/kg of body weight per day combined with the prescribing of ketoanalogues of essential amino acids, hyperglycemia control. With the progression of CKD, the main objectives of the diet therapy are the prevention/correction of complications: protein-energy waisting, metabolic acidosis, ensuring sufficient calories, corresponding to the bodys energy expenditures (3035 kcal/kg of body weight per day), limiting phosphate intake to 0.81 g a day, restriction of food potassium. Low-protein diet in combination with ketoanalogues of amino acids, regular monitoring and correction of the nutritional status of patients at the pre-dialysis stages of CKD is an effective and safe method of nephroprotection, which allows delaying the start of dialysis.

Published: July 2020

In this article we discussed the current state of monoclonal gammapathy of renal significance (Monoclonal Gammopathy of Renal Significance MGRS) and revealed problems of B-cell clone secreting nephrotoxic monoclonal immunoglobulin identification. We followed 276 patients with monoclonal gammapathy including patients with non-amyloid nephropathy. The majority of patients had systemic AL-amyloidosis. We established better survival of the treated patients with systemic AL-amyloidosis in comparison with retrospective untreated cohort. We considered current treatment of patients with non-amyloid nephropathy and focused on the crucial role of multidisciplinary approach in management of these patients.

Aim. Conducting a pilot study to assess the effect of thermal heliox on the state of the respiratory tract by studying of the exhaled breath condensate protein composition before the thermal heliox procedure, immediately after and after three hours of relaxation
Materials and methods. A comparative study of the exhaled breath condensates (EBC) protein composition of five non-smoking healthy donors was carried out. The EBC was taken before the respiratory procedure, immediately after a 20-minute inhalation by mixture of He/O2 gases (70/30) heated to 70C and 3 hours later. The protein composition was determined by chromatography-mass spectrometric analysis after selective tryptic hydrolysis. The results were processed using the Mascot program and the UniProt database.
Results. After the heliox procedure, the volume of the collected condensate (11.5 ml) decreases by an average of 32% and is practically restored after three hours of relaxation. Most proteins were consistent for all samples, regardless of the thermal heliox procedure. These are keratins, several proteins of the immune system (immunoglobulins, compliment proteins), tubulin. In samples after thermal heliox, the appearance of small amounts of additional proteins is observed. These are proteins of muscle metabolism (actin and calmodulin), fibrinogen, traces of hemoglobin, apolipoprotein, type B creatine kinase. After three hours of relaxation, tubulin disappears in the EBC.
Conclusion. Most exhaled proteins are the same before, after the procedure, and for three hours of relaxation. The results obtained demonstrate the relative safety of the use of high temperature heliox as a therapeutic agent.

The intestinal microbiota modulates immune programming and can prevent the realization of an allergic phenotype. For the formation of a normal microbiocenosis of the intestine, skin and oral cavity, a sufficient quantitative and qualitative bacterial colonization of the newborn is necessary during the transition from a sterile intrauterine environment to microbial colonization, resulting in the appearance of more than 1014 microorganisms. Low levels of bifidobacteria and early colonization of potentially pathogenic bacteria are associated with the development of severe allergic reactions. Prescribing probiotics containing Lactobacillus rhamnosus GG (LGG) at a concentration of 1081010 CFU from 36 weeks of gestation and during the first 34 months of lactation is associated with a 21% reduction in the risk of allergic reactions in the child.
