Conclui-se que se o tema TI verde for inserido de forma efetiva no setor de TI da organizacao, sera possivel elaborar politicas, acoes e estrategias bem definidas e promover o comprometimento de todos, fazendo com que a organizacao possa contemplar ao mesmo tempo os beneficios ambientais, sociais e economicos para o empreendimento.
IMPACT OF SELECTED DETERMINANTS OF CORPORATE GOVERNANCE ON FINANCIAL PERFORMANCE OF COMPANIES

The role of corporate governance (CG) is to ensure functioning of companies in accordance with their formulated objectives to ensure growth of corporate assets and satisfaction of the owners. In addition to management of the company, there are other stakeholders whose interests need to be considered in meeting the owners' objectives. These include creditors, employees, clients, and the wider context of the business. The aim of this paper is to explore and compare the impact of selected financial and non-financial determinants representing the interests of these groups on corporate financial performance. The influence of determinants of CG on financial performance, measured by return on assets (ROA), return on equity (ROE) and return on sales (ROS) indicators, is investigated by means of correlation analysis. The sample of enterprises used consists of non-financial joint-stock companies listed on the Bratislava Stock Exchange, insurance companies, and banks based in Slovakia. The findings show that each of the investigated determinants of CG affects financial performance of companies. ROA, ROE and ROS of share issuers are significantly influenced by the total equity (EQ), average remuneration (AR) and number of the Board of Supervisor members (BSM). With banks, performance indicators are only influenced by total personal costs (PC). ROA, ROE and ROS of all companies are influenced by the dividend ratio (DR), EQ, AR and BSM.
Critical care management in burns: a review of current evidence and guidelines - Part 2

Recent literature on the management of critically ill patients has altered the beliefs and clinical behaviours, questioning many dogmas that were practised without much evidence. The critical care in a severely burn-injured patient requires special attention in resuscitation, haemodynamic monitoring, management of complications, organ support and determinants of outcome. The goal of resuscitation is to maintain intravascular volume and tone while correcting the reversible changes in altered physiology, aided by early debridement of burned tissue and elimination of the source of physiological derangement. Practitioners should target resuscitation based on goal-directed therapy using non-invasive markers of cardiac output. The management requires the input of a multi-disciplinary team to achieve critical care and early surgical intervention and management of complications and organ support.

Parametric Study and Process Evaluation of Fenton Oxidation: Application of Sequential Response Surface Methodology and Adaptive Neuro-Fuzzy Inference System Computing Technique

The Fenton oxidation is rarely used industrially due to its high operating cost, large chemical consumption, excessive sludge production, and operability only within a narrow pH range. Therefore, there is a need to evaluate the Fenton oxidation to maximize its ability to degrade high-strength dye wastewater at reduced operating cost. Optimization tools are among the most commonly used tool to maximize the degradation of pollutants. The current study aims at evaluating the applicability of response surface methodology (RSM) and adaptive neuro-fuzzy inference system (ANFIS) to optimize the degradation of Remazol brilliant blue through the Fenton oxidation. The effects of four operating parameters including dye concentration, retention time, and mass ratios of Dye:Fe2+ and H2O2:Fe2+ were evaluated by applying RSM. According to the RSM results, color and chemical oxygen demand (COD) removal of 99.9% and 84%, respectively, were obtained at 120 min at the COD value of 795 mg/L, mass ratios of Dye:Fe2+ = 16, H2O2:Fe2+ = 15 and pH = 3. ANFIS was also used to evaluate the most influential operating parameters on the COD removal based on the RSM results. The ANFIS results showed that the mass ratio of H2O2:Fe2+ had the most significant contribution to the COD removal. High R2 values (≥90%) indicated that the predictions of RSM and ANFIS models for COD removal were acceptable. In conclusion, this study demonstrated that RSM and ANFIS were able to determine the most significant operating parameters and optimum ratios of pollutant:oxidant:catalyst, which reduced the operating cost directly.
Breast Sarcomas: Rare but Challenging Entity for Diagnosis

Background: Breast sarcomas are extremely rare, can be primary or secondary, pose a high risk of recurrence with an overall poor prognosis. Primary breast sarcomas constitute < 1% of all primary breast malignancies and less than 5% of all sarcomas. Sarcomas arising in phyllodes tumors account for < 6 % of all phyllodes tumors. The most common subtype of both primary and secondary sarcoma is angiosarcoma. Methods: This was a retrospective study of patients diagnosed as sarcoma of breast (excluding malignant phyllodes and metaplastic carcinoma) during the period from January 2016 to July 2019. The demographic and clinical features were noted from the medical records. The details of gross specimens (grossed in strict accordance with CAP protocols) were noted. The haematoxylin and eosin-stained slides along with immunohistochemistry (IHC) (pan cytokeratin, calponin, vimentin, SMA, CD117, Ki 67, desmin, CD10, CK5/6, EMA, p63, CD34, CD56, myogenin, CD99, p16, S100, BCL2, CD31, caldesmon and CD68) were reviewed and categorized according to WHO (2019) criteria. Result: The median age of patients was fifty years. There were fourteen breast sarcomas including one arising in phyllodes tumor during the study period. These included undifferentiated pleomorphic sarcoma (4), liposarcoma (2), myxofibrosarcoma (2), angiosarcoma (2), one each of leiomyosarcoma, rhabdomyosarcoma, fibrosarcoma and stromal sarcoma. Despite using a wide panel of IHC markers, 4/14 (28.57%) sarcomas were classified as undifferentiated pleomorphic sarcoma. Conclusion: Primary breast sarcomas are rare tumors and pose diagnostic challenge. It is important to categorize these entities in view of the differing biologic behavior and molecular profiles. Morphology along with IHC is important for diagnosis, treatment and prognosis.
Qualitative and quantitative determination of main alkaloids of Chelidonium majus L. using thin-layer chromatographic-densitometric method

We present a new simple thin-layer chromatographic method designed for determination of the main alkaloids of Chelidonium majus L. In this study, we used roots and herb of the plant collected in spring and autumn. The alkaloid fractions were prepared according to modified pharmacopeial procedure [1]. In our method, we performed two-step elution onto silica gel plates. The first eluent consisted of chloroform, methanol, and water mixed with 70:30:4 proportion. The second eluent comprised of toluene, ethyl acetate, and methanol with 83:15:2 proportion. The described thin-layer chromatography (TLC) system allows qualitative and quantitative determination of the following alkaloids: sanguinarine, chelerythrine, chelidonine, coptisine, and berberine. For determination of protopine, eluent with n-buthanol, acetic acid, and water in 15:1.5:4 proportion was investigated. The dominant alkaloids observed in studied fractions were coptisine (1027.096 ± 13.367–287.474 ± 3.069 mg/100 g dry matter ± sdv) and chelidonin.
The Continuous Intention to Use E-Learning, from Two Different Perspectives

During the recent vast growth of digitalization, e-learning methods have become the most influential phenomenon at higher educational institutions. E-learning adoption has proved able to shift educational circumstances from the traditional face-to-face teaching environment to a flexible and sharable type of education. An online survey was conducted, consisting of 30 teachers and 342 students in one of the universities in the United Arab Emirates. The results show that teachers’ and students’ perceived technology self-efficacy (TSE), ease of use (PEOU), and usefulness (PU) are the main factors directly affecting the continuous intention to use technology. Instructors’ technological pedagogical content knowledge (TPACK) and perceived organizational support (POS) positively affect the intention to use the technology, whereas students’ controlled motivation (CTRLM) has a greater influence on their intention to use the technology, due to the type of intrinsic and extrinsic motivation that they have and which they can develop throughout the process of learning. The findings support the given hypotheses. In addition, they provide empirical evidence of a relationship between perceived organizational support and perceived pedagogical content knowledge. In fact, they are considered the key factors that support the use of technology continuously.
PREVALENCE OF OSTEOPOROSIS IN RELATION TO SERUM CALCIUM AND PHOSPHORUS IN AGING WOMEN

Osteoporosis is increasingly being recognized by the medical fraternity as a significant health problem. This research was designed to study the incidence of osteoporosis in post-menopausal women and its relation to body mass index, body muscles, body fat and mineral status (calcium and phosphorus). Thirty samples of post-menopausal women aging between 45-60 years were divided into 3 groups. Body weight and height seemed to be tested through the use of electronic weighing balance and Stadiometer. Body muscles and fat percentage were determined through Beurer GmBH BLACK Blr.64. Bone mineral density was calculated by bone densitometry. Serum concentration of calcium and phosphorus was determined by spectrophotometer. The data obtained was subjected to Analysis of Variance. Results showed the significant decrease in body muscle, bone mineral density and serum calcium with increasing age. It was concluded that body weight, body muscles, body fat, bone mineral density, serum calcium and phosphorus had significant association with age and osteoporosis. Body fat and serum phosphorus increases with age in post-menopausal women. Body mass index and height had non-significant association with age and osteoporosis.
Stepping up: the need for Proactive Employer Investment in Safeguarding Seafarers’ Mental Health and Wellbeing

ABSTRACT In recent years mental health has been identified as a significant issue for the global workforce. In the shipping industry charities and insurance companies have raised concerns about seafarers’ mental health and wellbeing and have suggested a range of largely reactive and behaviour-based remedies and risk mitigation strategies. This paper contributes new data to the existing debates around seafarers’ welfare and mental health by exploring stakeholder and employer attitudes and approaches to the mental health and wellbeing of seafarers working aboard deep-sea cargo vessels, alongside the views and perceptions of active seafarers themselves. Unusually, the central focus is on what seafarers themselves consider to be supportive of their own happiness and wellbeing. Drawing on these two major sources of data the paper recommends a range of practical steps which should be taken by employers to mitigate seafarers’ exposure to a variety of risk factors associated with unhappiness and poor mental health. These recommendations relate to the shipboard provision of communication facilities, food, recreational facilities, shore-leave, work to leave ratios, bullying and harassment, furnishings, officer training and the provision of counselling services.
Impact of global warming on Potential Years of Life Lost by cardiopulmonary diseases in Brazilian capital cities

This study aims at assessing the future impact of global warming in the Potencial Years of Life Lost (YLL) for cardiovascular diseases in adults (â‰¥45 years) and respiratory diseases in the elderly (â‰¥60 years). This is an ecological study, which includes all the capitals of Brazil. Future projections used temperature data sourced from the Eta-HadGEM2S Regional Model for the RCP8.5 scenario. YLL fractions attributable to temperature were estimated for global warming scenarios of 1.5°C, 2.0°C, and 4.0°C. The results showed that, in absolute numbers, Rio de Janeiro and Sao Paulo have presented the largest YLL contribution attributable to global warming among the capital cities. Campo Grande and Cuiaba were the most impacted capitals by a global warming of 1.5oC compared to the baseline period (1961-2005), both for respiratory diseases in the elderly and for cardiovascular diseases in adults. Results of this research suggest that the impact of exposure to temperature on YLL tends to increase as the level of global warming increases.
The Pliocene Lillo, Poederlee, Merksplas, Mol and Kieseloolite Formations in northern Belgium: a synthesis

The Pliocene of Belgium subcrops in the northern part of the country and for more than a century has been the subject of many palaeontological and stratigraphical studies thanks to numerous temporary excavations that became accessible during the civil works for the expansion of the Antwerp Harbour. It was only during subsurface mapping from the 1980s onwards, in combination with cored and geophysical logged drillings, that these data became integrated which has led to new stratigraphical insights. The data relating to the current stratigraphy have now been inventoried, assessed, synthesized and a refined stratigraphical framework and correlation scheme is presented.
Polarised Facebook Discourse on Anglophone Nationalism in Cameroon

Technological advances have decentralised public communication through networked digital communication. The present paper seeks to critically analyze Facebook contradictory discourses and conversations on the future of the English-speaking regions of Cameroon. In November 2016, the Anglophone population engaged in civil disobedience against the Government of Cameroon over nonchalant attitude towards its predicament or refusal to address its grievances. Focus is on trolls and polarized conversations and discourses made by Anglophone activists on Facebook regarding the socio-political crisis troubling Cameroon since the end of the year 2016. Using Critical Discourse Analysis (CDA) as a methodological and theoretical approach, this study shows that there are two opposing views on Facebook: the separatists’ and the pro-unionists’ positions. On the one hand, the separatist activists through their Facebook posts discourse repudiate the pan-Cameroonian identity which they associate with francophonisation and cultural assimilation, and promote a separate Anglophone nationalism. On the other hand, the pro-unity Anglophone activists defend national unity and reject the secessionist discourse, thereby reproducing and expressing their adherence to the Pan-Cameroonian identity. This study will try to go beyond linguistic elements analysis to include a systematic construction of the historical and political, sociological and/or psychological dimension in the analysis and interpretation of specific texts/discourse.
Effect of Alloying on the Nucleation and Growth of Laves Phase in the 9–10%Cr-3%Co Martensitic Steels during Creep

Five Co-modified P92-type steels with different contents of Cr, W, Mo, B, N, and Re have been examined to evaluate the effect of the chemical composition on the evolution of Laves phase during creep at 650 °C. The creep tests have been carried out at 650 °C under various applied initial stresses ranging from 80 to 200 MPa until rupture. An increase in the B and Cr contents leads to a decrease in the size and volume fraction of M23C6 carbides precipitated during tempering and an increase in their number particle density along the boundaries. In turns, this affects the amount of the nucleation sites for Laves phase during creep. The (W+Mo) content determines the diffusion growth and coarsening of Laves phase during creep. Susceptibility of Laves phase to coarsening with a high rate is caused by the large difference in Gibbs energy between fine and large particles located at the low-angle and high-angle boundaries, respectively, and can cause the creep strength breakdown. The addition of Re to the 10%Cr steel with low N and high B contents provides the slowest coarsening of Laves phase among the steels studied.
A fenntarthatóság társadalompolitikai indikátorai és azok hazai teljesülése

The phenomenon of sustainability and sustainable development is one of the most current and most researched domains. In our present study a close, historic approach is applied to the conceptual framework of these two concepts and their relation. Besides presenting the evolving definition of sustainability, our work aims to examine the available indicators and set of indicators to measure general sustainability from the viewpoint of social policy; furthermore, the questions arising from their application in practice are analysed. We concluded in our paper that the concept of sustainability is well-researched and developed, in contrast, the indicators measuring it need further elaboration. Finally, the last section studies the realisation and evolution of the available social policy indicators of sustainability in Hungary.
