A study of project managers’ choice on key methods, tools and techniques in managing engineering projects
Authors: Radujković Mladen , Klepo Mariela Sjekavica 
Published: April 2021

AbstractThere is no doubt that each project manager uses different methodologies, methods, tools and techniques (MMTTs) while dealing with constant pressure to deliver results in a complex and changing environment, where complexity and stakeholders’ expectations are continually growing. This article presents results from the study about project managers’ choice on artefacts that they frequently use in their regular work. This study was conducted within the context of selected environment (one country and one sector of engineering projects), but designed methodology and results might also be significant for a wider audience. The results were based on the feedback that were received from 31 project management (PM) professionals gathered in the form of a structured questionnaire, followed by an interview with three PM experts for validation. The results confirmed a variety of PM artefacts in use and provided their ranking by perceived usefulness. The additional results indicated correlation between PM success and usage of MMTTs, as perceived by project managers. This study also resulted in several interesting findings, such as popularity and usefulness of artefacts, rigidity of PM processes, and maturity of PM organizations, about the topic. Despite of rather small sample taken from one country's environment, the results could serve as a solid information for moving ahead, while considering the significance of PM artefacts, as well as for their further development. The key findings are also messages to PM professionals to consider whether they use available and appropriate PM artefacts and is there a room for more efficient and effective usage.

Abstract
Motivation plays a critical role in L2 language learning and has proven to be a strong predictor of success in learning a foreign language (Biedroń & Pawlak, 2016). The Second Language Motivational Self System (L2MSS) is one of the most prominent theories developed by Dörnyei (2009), which has been studied in relation to different variables affecting language learning motivation. The aim of the present study is to examine the relationship between L2MSS components, international posture, and socioeconomic status among university students. The participants of this study were 134 non-English major university students. The results suggest that the ideal L2 self, and the L2 learning experience are related to international posture insert a comma after posture whereas the L2 learning experience is a stronger predictor of students’ motivated behavior. Future research should investigate the development of future selves in instructed language learning contexts conducive to enhancing and increasing motivation to learn English.
Privacy-Preserving & Incrementally-Deployable Support for Certificate Transparency in Tor

Published: April 2021

Abstract
The security of the web improved greatly throughout the last couple of years. A large majority of the web is now served encrypted as part of HTTPS, and web browsers accordingly moved from positive to negative security indicators that warn the user if a connection is insecure. A secure connection requires that the server presents a valid certificate that binds the domain name in question to a public key. A certificate used to be valid if signed by a trusted Certificate Authority (CA), but web browsers like Google Chrome and Apple’s Safari have additionally started to mandate Certificate Transparency (CT) logging to overcome the weakest-link security of the CA ecosystem. Tor and the Firefox-based Tor Browser have yet to enforce CT.
In this paper, we present privacy-preserving and incrementally-deployable designs that add support for CT in Tor. Our designs go beyond the currently deployed CT enforcements that are based on blind trust: if a user that uses Tor Browser is man-in-the-middled over HTTPS, we probabilistically detect and disclose cryptographic evidence of CA and/or CT log misbehavior. The first design increment allows Tor to play a vital role in the overall goal of CT: detect mis-issued certificates and hold CAs accountable. We achieve this by randomly cross-logging a subset of certificates into other CT logs. The final increments hold misbehaving CT logs accountable, initially assuming that some logs are benign and then without any such assumption. Given that the current CT deployment lacks strong mechanisms to verify if log operators play by the rules, exposing misbehavior is important for the web in general and not just Tor. The full design turns Tor into a system for maintaining a probabilistically-verified view of the CT log ecosystem available from Tor’s consensus. Each increment leading up to it preserves privacy due to and how we use Tor.

Published: April 2021

Abstract
Cameras are everywhere, and are increasingly coupled with video analytics software that can identify our face, track our mood, recognize what we are doing, and more. We present the results of a 10-day in-situ study designed to understand how people feel about these capabilities, looking both at the extent to which they expect to encounter them as part of their everyday activities and at how comfortable they are with the presence of such technologies across a range of realistic scenarios. Results indicate that while some widespread deployments are expected by many (e.g., surveillance in public spaces), others are not, with some making people feel particularly uncomfortable. Our results further show that individuals’ privacy preferences and expectations are complicated and vary with a number of factors such as the purpose for which footage is captured and analyzed, the particular venue where it is captured, and whom it is shared with. Finally, we discuss the implications of people’s rich and diverse preferences on opt-in or opt-out rights for the collection and use (including sharing) of data associated with these video analytics scenarios as mandated by regulations. Because of the user burden associated with the large number of privacy decisions people could be faced with, we discuss how new types of privacy assistants could possibly be configured to help people manage these decisions.

Abstract

Introduction. Pure extra-thoracic sarcoidosis is rare and poorly characterized in the literature. Herein we present features of pure extra-thoracic sarcoidosis, in comparison with sarcoidosis with intra-thoracic involvement, in a population from the south of Tunisia.

Methods. Retrospective, descriptive and comparative study of the patients presenting systemic sarcoidosis and attending the Department of Internal Medicine at the Hedi Chaker University Hospital, Sfax, Tunisia, for 21 years, from January 1996 to December 2016.

Results. Twenty-four patients presented pure extra-thoracic sarcoidosis (30% of the cases of systemic sarcoidosis). There was a female predominance (79%). The mean age was 50 years. The main features were polyadenopathies (10 patients: 41.7%), cutaneous involvement (10 patients: 41.6%), inflammatory polyarthralgia (8 cases: 33.3%), general symptoms (6 patients: 25%), uveitis (6 cases: 25%), cholestasis (3 cases) and kidney involvement (2 cases). Lymphopenia, hypercalcemia, and hypercalciuria were observed each one in 12.5% of the cases, and high angiotensin converting enzyme (ACE) level in 38.5% of the cases. The histological proof was required in all the patients. Statistically significant associations identified were mainly hepatic involvement with general symptoms (p=0.035), peripheral lymphadenopathies (p=0.035) and kidney damage (p=0.022), and cutaneous involvement with articular manifestations (p=0.032). Systemic corticosteroids were used in half of the cases, with a good outcome in 21 cases, and recurrence in two cases. One patient was lost to follow up. The comparison to the form with mediastino-pulmonary involvement showed less lymphadenopathies (p=0.001), less lymphopenia (p=0.006), and less frequent use of corticosteroids (p=0.044).

Conclusion. Our series was characterized by the frequency of the pure extra-thoracic form and the diversity of the systemic manifestations.

Abstract
In this paper, a rail joint model consisting of three Euler-Bernoulli beams connected via a Winkler foundation is proposed in order to point out the influence of the joint gap length upon the stiffness of the rail joint. Starting from the experimental results aiming the stiffness of the rail joint, the Winkler foundation stiffness of the model has been calculated. Using the proposed model, it is shown that the stiffness of the rail joint of the 49 rail can decreases up to 10 % when the joint gap length increases from 0 to 20 mm.

Georg Wilhelm Pabst : blessure de la guerre, cicatrices de la pellicule
Authors: Dumas Louise 
Published: April 2021

Abstract
Von allen Filmemachern, die Deutschlands filmischen Ruhm in der Zwischenkriegszeit ausmachten, ist G. W. Pabst derjenige, der am wenigsten Anerkennung erhielt – oder am längsten dafür gebraucht hat. Er ist aber auch derjenige, der schon Ende der 1920er Jahre den Ersten Weltkrieg zu einem filmischen Ereignis machte, das in vier seiner Filme mehr oder weniger direkt thematisiert wird: Die Liebe der Jeanne Ney, Westfront 1918, Kameradschaft und Mademoiselle Docteur. Der Krieg wird als eine traumatische Erfahrung dargestellt, die Einzelpersonen, Seelen und Völker verwundet hat. Dabei bilden auch diese vier Filme ein Manifest der Filmkunst, die grundsätzlich eine Dialektik vom Trennen und Verbinden ist. In diesem Sinne hat das Kino durch seine medienästhetischen Mittel die Kraft, die Wunden des Krieges zu verarbeiten und zu heilen.

Published: April 2021

AbstractSynchronization between female receptiveness and pollen dispersal, and fecundity of clones influence effective population size and genetic diversity of germplasm produced in seed orchards. Our objective was to determine clonal variation in phenological synchronization and in cone production in aPinus patulaseed orchard. Two-year phenology data of female and male strobili from a sample of 31 clones, and of male strobili in trees from neighboring natural stands of the same species were used. Synchronization indices between female receptiveness and pollen release of the same clone (O̅iP̅i), of other clones (O̅i P̅j), and of natural stands (O̅iP̅NS) were calculated for each clone and averaged per precocity group (early, intermediate, and late). Genetic parameters for cone production of clones during three consecutive cone harvests were estimated, as was their relationship to precocity and synchronization index O̅iP̅NS. Cone production showed a broad variation among clones and between years, with strong genetic control (H2c ≥ 0.80) and stable (rB ≥ 0.79) between yeas. There was wide clonal variation in synchronization indices, but no significant variation was found in most cases among precocity groups, neither were they consistent between years. Negative correlations [rp= -0.37 and -0.40 (P< 0.05)] in cone production per clone in two years with the O̅iP̅NSindex in the first year, indicated that the most prolific clones had lower synchronization with pollen release in natural stands in the orchard’s vicinity, and thus less risk of genetic contamination.
Enhanced Eddy Current Techniques for Detection of Surface-Breaking Cracks in Aircraft Structures
Authors: Uchanin Valentyn 
Published: April 2021

Abstract
Well-timed detection of the defects (e.g., fatigue cracks and corrosive damages) in aircraft structures is the question of vital importance. Periodic in-service non-destructive inspection (NDI) is necessary to prevent expensive aircraft breakdowns during in-service life. Eddy current (EC) NDI method have many advantages for in-service aircraft inspection due to high mobility and the possibility to detect fatigue cracks without direct contact with the inspected surface (even through a protective coating without removal). Last decades some enhanced EC techniques were developed for aircraft in-service inspection in the Karpenko Physico-Mechanical Institute of National Academy of Sciences (Lviv) in collaboration with Ukrainian and foreign aircraft companies.
Proposed earlier EC efficiency coefficient was applied for the selection of the ferrite-core EC probe parameters. Investigations concerned with the crack detectability for single-coil EC probes of different sizes were carried out to improve the inspection procedures. The sensitivity of the developed single-coil EC probe was experimentally investigated. The possibility to distinguish the signals associated with detected defect and lift-off was shown. The new inspection procedure was proposed for full suppression of the noise concerned with the rivet edge influence.
The high-frequency EC flaw detector of Leotest VD 3.03 type based on self-generator mode and miniature single-coil EC probes application was developed for detection of the surface-breaking fatigue cracks. The original scheme of double-circuit self-generator with intermittent oscillations was invented and investigated. The pulse-repetition frequency of high-frequency oscillations was used as an informative parameter. The important feature of the developed self-generating scheme is the effective suppression of the lift-off influence (the changes of the clearance between the EC probe and the inspected object surface during the scanning).
Developed EC flaw detectors of Leotest VD 3.03 type and inspection procedures were successfully implemented into the maintenance practice for detection of the fatigue cracks initiated in the wing and the fuselage structures and aviation engines in many companies such as ANTONOV AIRCRAFT, Lviv State Aircraft Repair Plant, Konotop aircraft repair plant «AVIAKON», Ukrainian International Airlines, MOTOR-SICH, State Enterprise “IVCHENKO-PROGRESS”, etc.
Incomplete Transition – Is there a “Mid-Transition Trap”?
Authors: Vujačić Ivan , Petrović-Vujačić Jelica 
Published: April 2021

Abstract
The subject of this paper is the analysis of the classification of economic systems. The traditional classifications of capitalist, socialist centrally planned, and socialist market systems, and the newer classification of variants of capitalism into the Anglo-Saxon, European continental, and Asian models, are inadequate to explain new phenomena in a globalized economy. After the collapse of central planning, countries in transition became a category describing processes of deep socio-economic transformation. These transition countries aspired to meet the standards of developed European market economies, as well as governance standards regarding democracy, human rights, and the rule of law. A new classification of economic systems by Balcerowicz (2014) combines the traditional classification of economic systems with the characteristics of well-governed democratic societies in order to come up with a matrix that shows the interaction of economic system characteristics and governance outcomes.This paper builds on Balcerowicz’s classification by introducing and delineating the categories of state capitalism, crony capitalism, and state capture in order to provide a new classification of economic systems. It uses these concepts to empirically analyze the transition countries, with special reference to states aspiring to EU membership and the new EU member states. The methodology used is analytical and empirical. The results find that the transition is incomplete, especially in terms of governance, leading to the hypothesis of a ‘mid-transition trap’, similar to the much discussed ‘middle-income trap’. The results should lead to further, more refined research.

You cannot always warfawin: a case of significant INR fluctuation with brand to generic conversion of warfarin
Authors: Nixon Christopher G. , Steuber Taylor D. 
Published: April 2021

Background:
Warfarin is affected by many variables such as diet, alcohol, and medications; however, it is unclear if brand to generic conversion may also play a role. This case reports a patient with fluctuating international normalized ratio (INR) while being switched from brand to generic temporarily.

Case Presentation:
A 60-yearold obese white male taking brand name Jantoven© (warfarin) at home for 9 years at a consistent dose for atrial fibrillation was in hospital for treatment of cellulitis. He was switched to generic warfarin at his home dose on admission. While in hospital, he required dose escalation to three times his home dose to achieve a therapeutic INR.

Conclusion:
Generic warfarin may have different effects on INR when compared to brand name Jantoven©. More research is warranted to determine if differences may truly exist and potential ways to address the issue. Until then, providers should be cognizant of interchanging the two products to monitor for INR variation.

Published: April 2021

Acute respiratory viral infections (ARI) and influenza occupy a leading place in the structure of the overall morbidity of the population in most countries.
Aim. To assess the rational prescription of drugs for etiotropic therapy of ARI in the outpatient practice.
Materials and methods. The following materials for research were used: case histories; treatment sheets; the Unified clinical protocol of primary care for adults and children “Acute respiratory infections”; data of the State Formulary of Medicines as of January 2021; the Register of wholesale prices; the weekly “Apteka” (Pharmacy). The methods of retrospective, descriptive, frequency, and VEN-analysis were applied.
Results. According to the research results, using patient histories, it was found that family doctors prescribed 67 drugs by trade names. For etiotropic therapy, 24 drugs were used; it was 37 % of the total number, and 63 % – for symptomatic therapy. Such drugs as Amizon, Aflubin, Amixin, Resistol, Umkalor were for etiotropic therapy (more than 5 prescriptions). None of these drugs is included in the State Formulary of Medicines and the Unified clinical protocol for the treatment of influenza and SARS. Thus, these drugs are without the proven efficiency, safety and cost-effective use.
Conclusions. The study conducted has shown that the drugs prescribed most often do not have an evidence base of efficacy and safety; none of the most frequently prescribed drugs is included in the State Formulary of Medicines and the Unified clinical protocol. A direct relationship between an increase in the number of prescriptions and an increase in price has been proven.

Published: April 2021

Aim. To analyze the range and assess the economic availability of nootropic drugs at the Ukrainian pharmaceutical market in 2018.
Materials and methods. The study object was information about nootropic drugs available at the pharmaceutical market of Ukraine in 2018 based on the data of the “PharmXplorer” analytical system of the information retrieval company “Morion”. The study included drugs used for the treatment of cerebrovascular diseases from the N06B X pharmacotherapeutic group (according to the ATC classification) – “Other psychostimulative and nootropic drugs”. An indicator of the adequacy of solvency (Ca.s.) was calculated using the data taken on the prices of drugs and the average level of wages for 2018.
Results. At the Ukrainian pharmaceutical market in 2018 a wide range of nootropic drugs was presented. The range of retail prices per drug pack was significant, indicating the possibility of a doctor and a patient to choose the drug taking into account its efficacy, safety and affordability. Most trade names of nootropics (52 %) were registered as oral dosage forms, being compliant for patients with chronic cerebral circulatory disorders. 48 % were injectable and infusion drugs, which were topical for acute ischemic attack.
Conclusions. It was found that in 2018 drugs containing piracetam, vinpocetine, gamma-aminobutyric acid (GABA) and its derivatives, most drugs based Phenibut (84.6 % of TN) and citicoline (68 % of TN) were highly available to the consumer. Most of the injectable dosage forms of nootropics based on hydrolyzates and tissue derivatives were readily available (50 % of TH) for the average consumer in Ukraine. Considering a fairly wide range of nootropic drugs and the economic availability of most of them the principle of superiority of clinical efficacy, safety and affordability should be the basis for creating and developing new nootropic drugs.
Key words: nootropic drugs; assortment; economic affordability; Ukrainian pharmaceutical market.
