Research Regarding the Reactions of Romanian Facebook Users on COVID-19 Pandemic

Social media plays a very important role during difficult periods like the one we are living in right now due to the life-threatening COVID-19 pandemic. People get online news in real time about statistics, rules that were imposed by the authorities or about personal experiences shared by others in order to raise awareness, to manipulate or to get a certain type of attention. The individuals have a predisposition to take decisions based on what they are seeing on social media and their decisions have a great impact on health as well as on economy trends. The purpose of our study was to examine the social media coverage and to identify the reaction of people following specific posts as well as to check whether if there has been a link between their online reaction and the general trend of the virus in Romania, knowing that the country is more and more affected daily by this pandemic. For this study, we have used exploratory research of in-depth content analysis in order to understand the reactions to the daily news published by a national authority. We collected secondary data from Facebook posts, analysing the reactions used in terms of “emojis”, as well as the number of comments and the number of shares, comparing their reaction to the number of sick people in that specific period. Our results show that the number of reactions to the posts has decreased but people use all kind of emojis they have at their disposal, mostly the classic “like” but also the “angry”, “haha” in order to express emotions and beliefs and this could be associated with their behaviour in real life during pandemic.
[Chronic kidney disease among adults in Rio Branco, State of Acre: a population-based survey].

The scope of this study was to establish the prevalence of CKD and associated factors among young adults (18-59 years of age) from Rio Branco in the State of Acre. It involved a population-based survey conducted in 2014, in the urban and rural areas of the municipality and CKD was defined as the glomerular filtration rate (GFR) < 60ml/min/1. 73m², estimated by the CKD-EPI, and the presence of albuminuria > 29 mg/g. Association measures were estimated by logistic regression, with a confidence level of 95%. The overall prevalence of CKD was 6.2%. The presence of CKD was higher among women, aged 40 to 59 years, with non-white skin color, with lower schooling, and of sedentary disposition. There were statistically significant differences in the distribution according to the presence of CKD in the hypertension, diabetes and hospitalization variables over the past 12 months. CKD among adults was associated with the female sex (OR: 2.41, 95%CI: 1.14-5.12), diabetes (OR: 4.67, 95%CI: 1.28-17.03) and arterial hypertension (OR: 1.98; 95%CI: 1.16-3.37). CKD reveals a high prevalence and is associated with chronic diseases, calling for the need for public health measures for early detection and prevention of its progression.
Shearing in High Strength Concrete Bridge Girders: Technical Report

Prestressed Concrete (PC) I-girders are used extensively as the primary superstructure components in Texas highway bridges. A simple semi-empirical equation was developed at the University of Houston (UH) to predict the shear strength of PC I-girders with normal strength concrete through the project Texas Department of Transportation (TxDOT) 0-4759. The UH-developed equation is a function of shear span to effective depth ratio, concrete strength, web area and amount of transverse steel. This report intends to: (1) validate the UH-developed equation for high strength concrete by testing ten 25-ft long full-scale PC I-girders with different concrete strength; and (2) validate the UH-developed equation for different sizes of PC girders and study the possibility of having premature failure due to local failure in end zone. Ten modified Tx28 PC girders were tested for the first objective. The girders were divided into three groups (namely Groups A, C and F) based on the concrete compressive strength. Group A consisted of two girders with a concrete compressive strength of 7000 psi. Group F had four girders with a concrete compressive strength of 13000 psi and Group C included four girders with a compressive strength 16,000 psi. Girders in Group A were designed to have a balanced condition in shear. A pair of girders each belonging to Group F and Group C were designed to have a balanced condition while remaining girders were designed as over-reinforced sections. Each group of the PC girders was tested with different shear span to effective depth ratio so as to get two types of shear failure modes, i.e., web-shear and flexure-shear. The validity of the proposed UH-developed equation was ascertained using the girders test results. UH-developed equation was found to accurately predict the ultimate shear strength of PC girders having concrete strength up to 17,000 psi with enough ductility. Six PC girders of Tx-series with three different sizes were tested for the second objective. The girders were divided into three groups (namely Groups D, E and G) based on the girder depth. The test data shows that the PC girders of the new Tx-series has no cracks under service loads and can reach the maximum shear capacity without having a shear bond failure. Also, these girders’ test results ensured the validity of the UH-developed equations for PC girders with different sizes. Simulation of Concrete Structures (SCS), a finite element program recently developed at UH, was used to predict the shear behavior of the tested girders. Analytical results presented in this report proved the validity of SCS to predict the behavior of PC girders with different concrete strength up to 17,000 psi and with different depth up to 70 inches.
Electrical Power System of the NTNU Test Satellite: Design of the EPS

The NTNU Test Satellite (NUTS) project is aiming to launch a 10×10×20 cm nanosatellite by the year 2014. The goal is to design and develope a low cost satellite by exploring the use of commersially available components. This work will focus on the power system of the NUTS satellite, which consists of a power distribution system, the backplane, and a power condition system, the Electrical Power System (EPS). This thesis describes the design and evaluation of the EPS module, which is a critical part of the satellite, because without power the satellite will not be able to operate. The electrical power system of the satellite consists of the solar cells, batteries, and voltage converters. With limited power available, the main focus of the design has been to implement an efficient system with minimum losses in power conversions. The Electrical Power System (EPS) module has been designed with simplicity, reliability, and redundancy in mind. The designed is based on the requirements of a reliable power source, with the main goals of charging the batteries with power from the solar cells and regulate the battery voltage down to the requested voltages of the backplane. A charger is chosen for its abilities to provide efficient and safe charging by using proper strategies for efficient energy harvesting and charging. To accommodate the voltage request of the backplane, four fixed value regulators is chosen for the design. For power monitoring of the provided power from the solar cells and batteries, current monitor sensors are implemented after each charger circuit and the batteries. Based on the specification of the solar cells and the batteries a final design of the main functionalities has been provided and a prototype of the EPS module has been produced. The proposed solution offers a reliable and redundant system, where a loss of one charger or converter will not mean the end of the mission. The EPS module has been tested and evaluated, and displays good performance results in terms of charging the batteries and voltage regulation. The efficiency of the EPS chargers is found to be 95 %.
Medidas para estimar el rendimiento y capacidad de losprocesos software de conformidad con el estándarISO/IEC 15504-5:2006

At the moment is important to have got a set of metrics which measures the improvements brought in by efforts to make software processes better. It is often the case that these improvements are measured using informal and subjective processes based on the perception of employees and/or auditors. Bearing all this in mind, this work presents a set of measurements for gauging the performance and capability of software processes, based on the international standard ISO/IEC 15504. This set of metrics aims to lower the level of subjectivity of people when measuring the processes. A more objective and hence more formal evaluation is thus achieved.
BURNOUT PREVENTION WITH PSYCHOEDUCATION IN TEACHERS

Our research aims at prevention of burnout, which can be a protective factor in preventing career abandonment and can contribute to creating and maintaining a positive workplace climate. It also promotes the mental well-being and resilience of teachers and students. Therefore, burnout of teachers is especially important in Hungary, as the gradually increasing professional and administrative burden, the lack of social esteem, as well as the changed learning-teaching environment and the methodological shortcomings of general teacher training significantly increase the risk of burnout. In our research, the staff of the Somogy County Educational Service Center has been involved, mainly special education teachers. The 116-person sample has been conducted with a version of the Maslach Burnout Inventory developed for educators. In our presentation, the test results are presented. According to our findings, out of the three subscales of the subjects' questionnaire, the highest scores were achieved in the Emotional Exhaustion subscale and the lowest in the Depersonalization subscale. However, the emotional exhaustion subscale did not indicate a high burnout value in the study population. The correlations of burnout risk with age and time spent as a teacher has been also analyzed. Problem-focused and change-oriented psychological counseling models are attracting interest in the international literature today (Egan, 2010). By strengthening resilience and supporting a sense of growth, consultation techniques work to strengthen effective interpersonal communication and help the individual plan constructively for the future (Bonanno, 2004, 2005; Kelley, 2005; Linley & Joseph, 2005; Litz, 2005; Maddi, 2005). All of this are relevant to our research because we plan to provide burnout prevention psychoeducation counseling programs to educators. The literature also mentions the phenomenon of learned helplessness, which has its roots in childhood and is a breeding ground for both depression and burnout (Seligman,1991). Learned inertia can influence members of the helping professions toward passivity (paralysis, loss of control, hopelessness, unresponsiveness) and is therefore particularly burdensome for the individual, along with the challenges of helping professions. Results of our research shed light on the burnout level of special educators, personality traits important for coping and related burnout prevention (e.g., empathy, psychological immune competence) and the applied coping mechanisms that guide burnout prevention psychoeducation as a comprehensive concept.
Sustainability of Biodiesel Production and Usage: The Case of Romania

Background: This paper aims to evaluate the sustainability of biodiesel, a renewable fuel used as a blending component in diesel fuel. This study describes the current situation in Romania where the European Union (EU) settlement regarding the blending ratio of biodiesel and compliance with environmental protection specifications are applied. The evaluation covers the whole biodiesel value chain, from rapeseed production through biodiesel synthesis and combustion.Results: Our evaluation process takes into account three elements of sustainability: economic, environmental, and social. The overall result of this research is that, despite Romania’s high potential for biodiesel production and use, the sustainability of biodiesel is low as a result of the Romania’s government strategy, combined with biodiesel prices on the international market and the interests of Romanian refinery owners.Conclusions: Our prediction is that the current situation will remain over the next decade, owing to economic factors such as the decline in rapeseed crops, a key raw material for biodiesel manufacturing, and the higher cost of biodiesel produced in Romania. Another factor could be Romania's implementation of EU regulations aimed at replacing diesel engines with electric ones. If this decision is implemented, diesel fuel and, implicitly, biodiesel will be phased out of the vehicle fuel market.
Simulator Sickness: Sensorimotor Disturbances Induced in Flight Simulators,

Abstract : If sickness occurs in the simulator, but not in the real world, there is evidence of a bad simulation. We reviewed the available data on simulator sickness in terms of their incidence, etiology, and contributing factors. It was found that psychophysiological disturbances can occur during simulator flight, continue several hours post-flight, or be delayed. Effects were found in both motion-base and fixed-base simulators, to pilots, other aircrew, and instructors. Simulator sickness may lead to decreased simulator use, distrust of the training received, and post-effects which may place the individual at risk in real-life situations such as driving a car. Adaptation, while it is known to occur, is not the answer. Adaptation to the simulator can lead to acquisition of responses which may produce negative transfer to the aircraft. Data on the relative incidence of simulator sickness in various trainers, its symptomatology, possible etiology, possible solutions and suggestions for research are discussed. (Author)
On the state of the building industry after the GFC and the Euro crisis

There has been an intense debate in the media and among academics on how the great financial crisis has affected the global economy, and how the effects have differed in different regions of the world. This survey was designed to establish to what extent the building industry has been affected by the GFC and the Euro crisis. Over the last months we have asked senior academics and executives in construction businesses what has happened up to now in their region, what will most likely happen in the near future and in the long term. The answer is that in developed economies the effect has been a substantial downturn as finances have dried up while in developing economies in most regions, demand has been sustained due to population growth with ever increasing needs for residential building and infrastructure. While there is some apprehension about the potential effects of the Euro crisis deepening, no-one seems really worried. In the long term there is an agreement, in developed and developing countries alike, that current business models do not work and that the industry has to reinvent itself to be sustainable.

Company Web sites: information and how to find it

Points to the great improvement made by the Internet and the Web on the ability to find information on companies, particularly small and medium-sized companies. Presents useful advice on strategies to adopt in searching for information from company Web sites and available tools to facilitate searching, including: Web search engines; Internet service providers; and Yellow Pages and directories. Pays particular attention to the problem of Uniform Resource Locators (URLs) research. Stresses the great strength of company Web site information in that it differs from that available from standard company directories and is, therefore, complementary in character. Company Web sites are constantly changing and so offer insights into how companies are developing. Many small and medium-sized companies that had never been accessible through traditional online services are now accessible via the Internet.
Comparison of quench behaviour of different coated conductors

This paper presents experimental results of quench studies at short samples of YBCO coated conductors (CC) cooled in boiling liquid nitrogen at 77 K by varying the current. Coated conductors with different cap layers and stabilisations are used for these studies. Samples without any stabilisation, except the original silver layer as well as composite samples with an additional stabilisation of hastelloy or copper are systematically investigated for the use in superconducting fault current limiters (SCFCL). The variation of the sinusoidal current covers a wide range starting from currents below the critical current (Ic) up to currents of more than 10 times Ic. The test results show the excellent performance of homogeneous CC with a low stabilisation for the use in SCFCL in wide range of short circuit current amplitudes as well as the acceptable performance of inhomogeneous CC with a high stabilisation.
Implementation of Quality Management System in Sweco Norge

Good and appropriate quality management is a necessity for achieving competitive advantage within most industries, including the engineering consulting industry. In this case study factors contributing to or hindering quality management system implementation success in Sweco Norge AS have been examined. The study has shown that the benefits that the organization wishes to achieve by system use, how the system is designed to achieve those objectives and how different mechanisms that promote system use are utilized in the company will have an effect on the degree to which the system is used, and thus on the benefits achieved. It has further been shown that there is a discrepancy between how Sweco Norge intends to use the system and how it is actually used in the organization? s Hedmark-Oppland unit, and some reasons for this gap have been outlined. Finally, a framework based on change management principles has been developed that can be used by regional management to minimize this gap.
What is the right governance type for your maintenance

Many industrial firms focus on their core competencies and reduce their direct ownership over non-core functions. Maintenance activities are hard to classify as either core or noncore when being a support function to the core production in manufacturing firms. Further, maintenance activities encompass understanding of the interrelationship between processes in the production plant. The purpose of this study is to explore which governance types that are best suited for different kinds of maintenance. Based on a multiple case study within the process-industry, the study shows how a distinction between core-close and more distant maintenance informs the choice of governance model. Topics: Operation Strategy, Maintenance, Supply Chain Management
The confrontational management-labor negotiations that led to the failure of the United States motor vehicle companies and why the Japanese and Germans prevailed

The success of the US motor vehicle companies up to 1955 and their subsequent decline is directly related to the management-labor negotiations in the 1930s and the acceptance by both management and the mass union movement of the inherent nature of work in an assembly-line factory. Because the conditions of employment on the assembly line became less and less bearable over time, the negotiations became confrontational ones in which each side tried to get as much as possible from the other in a ? win-lose? setting. This ongoing confrontation let to the continuously escalating labor costs within the US motor vehicle companies that ultimately led to their decline. Unlike the case of Japanese or European companies, the US companies never had a ? win-win? proposal on the table. To understand how this happened, we will first describe how, on three occasions, the motor vehicle industry has changed the most fundamental ideas on how to manufacture things and, what is more important, how humans work together to create value.
Across‐Gimbal and Miniaturized Cryogenic Loop Heat Pipes

This paper describes the development status of three advanced cryogenic loop heat pipes (CLHP) for solving important problems in cryogenic integration. The three devices described herein are: (1) an across‐gimbal CLHP; (2) a short transport length miniaturized CLHP; and (3) a long transport length miniaturized CLHP. The across‐gimbal CLHP, which is baselined for operation from 80–100 K with nitrogen, provides a low weight, low torque, high conductance solution for gimbaled cryogenic systems wishing to mount their cryocoolers off‐gimbal. The short transport length miniaturized CLHP, which is baselined for operation near 35 K with neon, combines localized thermal transport, flexibility, and thermal switching into one device that can be directly mounted to a cryocooler cold head and a cryogenic component just a short distance (10–20 cm) away. The long transport length miniaturized CLHP, which is also baselined for operation near 35 K with neon, adds to the capabilities of the short transport length miniaturi.
