A Few Critical Human Factors for Developing Sustainable Autonomous Driving Technology
Authors: Cárdenas José Fernando Sabando , Shin Jong Gyu , Kim Sang Ho
Published: April 2020

The purpose of this study is to develop a framework that can identify critical human factors (HFs) that can generate human errors and, consequently, accidents in autonomous driving level 3 situations. Although much emphasis has been placed on developing hardware and software components for self-driving cars, interactions between a human driver and an autonomous car have not been examined. Because user acceptance and trust are substantial for the further and sustainable development of autonomous driving technology, considering factors that will influence user satisfaction is crucial. As autonomous driving is a new field of research, the literature review in other established fields was performed to draw out these probable HFs. Herein, interrelationship matrices were deployed to identify critical HFs and analyze the associations between these HFs and their impact on performance. Age, focus, multitasking capabilities, intelligence, and learning speed are selected as the most critical HFs in autonomous driving technology. Considering these factors in designing interactions between drivers and automated driving systems will enhance users’ acceptance of the technology and its sustainability by securing good usability and user experiences.
A Distributed Cooperative Control Strategy of Offshore Wind Turbine Groups with Input Time Delay
Authors: Wang Bing , Tang Zhen , Liu Weiyang , Zhang Qiuqiao
Published: April 2020

With large-scale development of offshore wind power and the increasing scale of power grid interconnection, more and more attention has been drawn to the stable operation of wind power units. When the wide area measurement system (WAMS) is applied to the power system, the time delay mainly occurs in the signal measurement and transmission of the power system. When 10MW wind turbines transmit information through complex communication network, time delay often exists, which leads to the degradation of performance and instability for system. This affects the normal operation of a wind farm. Therefore, in this paper, the distributed control problem of doubly fed wind turbines with input time delay is studied based on the Hamiltonian energy theory. Firstly, the Port-controlled Hamiltonian system with Dissipation (PCH-D) model is implemented with the Hamiltonian energy method. Then, the Casimir function is introduced into the PCH-D model of the single wind turbine system to stabilize the time delay. The wind turbine group is regarded as one network and the distributed control strategy is designed, so that the whole wind turbine cluster can remain stable given a time delay occurring in the range of 30–300 ms. Finally, simulation results show that the output power of the wind turbine cluster with input delay converges to the expected value rapidly and remains stable. Additionally, the system error caused by time delay is greatly reduced. This control method can effectively solve the problem of input time delay and improve the stability of the wind turbine cluster. Moreover, the method proposed in this paper can adopt the conventional time step of dynamic simulation, which is more efficient in calculation. This method has adaptability in transient stability analysis of large-scale power system, however, the third-order mathematical model used in this paper cannot be used to analyze the internal dynamics of the whole power converter.

Published: April 2020

The aim of this paper is to derive an equation for the temperature distribution in journal bearing oil film, in order to predict the thermal load of a bearing. This is very important for the prevention of critical regimes in a bearing operation. To achieve the goal, a partial differential equation of the temperature field was first derived, starting from the energy equation coupled with the Reynolds equation of hydrodynamic lubrication for a short bearing of symmetric geometry. Then, by solving the equation analytically, the function of temperature distribution in the bearing oil film has been obtained. The solution is applied to the journal bearing, for which the experimental data are available in the references. Finally, the obtained results have been compared to the corresponding experimental values for two operating regimes, and a good level of agreement was achieved.

Dihedral Group D4—A New Feature Extraction Algorithm
Authors: Sharma Puneet
Published: April 2020

In this paper, we propose a new feature descriptor for images that is based on the dihedral group D 4 , the symmetry group of the square. The group action of the D 4 elements on a square image region is used to create a vector space that forms the basis for the feature vector. For the evaluation, we employed the Error-Correcting Output Coding (ECOC) algorithm and tested our model with four diverse datasets. The results from the four databases used in this paper indicate that the feature vectors obtained from our proposed D 4 algorithm are comparable in performance to that of Histograms of Oriented Gradients (HOG) model. Furthermore, as the D 4 model encapsulates a complete set of orientations pertaining to the D 4 group, it enables its generalization to a wide range of image classification applications.
Reliability Improvement of LoRa with ARQ and Relay Node
Authors: Choi Rocksan , Lee SeungGwan , Lee Sungwon
Published: April 2020

In our modern world, many Internet of Things (IoT) technologies are being researched and developed. IoT devices are currently being used in many fields. IoT devices use Wi-Fi and Bluetooth, however, communication distance is short and battery consumption is high. In areas such as smart cities and smart farms, IoT technology is needed to support a wide coverage with low power consumption. Low Power Wide Area (LPWA), which is a transmission used in IoT supporting a wide area with low power consumption, has evolved. LPWA includes Long Range (LoRa), Narrowband (NB-IoT), and Sigfox. LoRa offers many benefits as it communicates the longest distances, is cheap and consumes less battery. LoRa is used in many countries and covers a range of hundreds of square kilometers (km2) with a single gateway. However, if there are many obstacles to smart cities and smart farms, it causes communication problems. This paper proposes two (2) solutions to this problem: the relay method which is a multi-hop method and the Automatic Repeat Request (ARQ) system that detects packet loss in real-time and requests retransmission for LoRa. In this study, the actual performance of LoRa in the problematic environment was measured and the proposed method was applied. It was confirmed that the transmission rate of LoRa dropped when there were many obstacles such as trees. To use LoRa in a smart farm with a lot of space, multi-hop was observed to be better. An ARQ system is needed to compensate for the unexpected drop in the forward rate due to the increase in IoT devices. This research focused on reliability, however, additional network methods and automatic repeat request (ARQ) systems considering battery time should be researched in symmetry. This study covers the interdisciplinary field of computer science and wireless low power communication engineering. We have analyzed the LoRa/LoRaWAN technology in an experimental approach, which has been somewhat less studied than cellular network or WiFi technology. In addition, we presented and improved the performance evaluation results in consideration of various local and climatic environments.

Authors: Adineh Zadeh Azam , Norouzi Morteza , Cristea Irina
Published: April 2020

On a particular class of m-idempotent hyperrings, the relation ξ m * is the smallest strongly regular equivalence such that the related quotient ring is commutative. Thus, on such hyperrings, ξ m * is a new representation for the α * -relation. In this paper, the ξ m -parts on hyperrings are defined and compared with complete parts, α -parts, and m-complete parts, as generalizations of complete parts in hyperrings. It is also shown how the ξ m -parts help us to study the transitivity property of the ξ m -relation. Finally, ξ m -complete hyperrings are introduced and studied, stressing on the fact that they can be characterized by ξ m -parts. The symmetry plays a fundamental role in this study, since the protagonist is an equivalence relation, defined using also the symmetrical group of permutations of order n.
Icosadeltahedral Geometry of Geodesic Domes, Fullerenes and Viruses: A Tutorial on the T-Number
Authors: Šiber Antonio
Published: April 2020

The Caspar–Klug (CK) classification of viruses is discussed by parallel examination of geometry of icosahedral geodesic domes, fullerenes, and viruses. The underlying symmetry of all structures is explained and thoroughly visually represented. Euler’s theorem on polyhedra is used to calculate the number of vertices, edges, and faces in domes, number of atoms, bonds, and pentagonal and hexagonal rings in fullerenes, and number of proteins and protein–protein contacts in viruses. The T-number, the characteristic for the CK classification, is defined and discussed. The superposition of fullerene and dome designs is used to obtain a representation of a CK virus with all the proteins indicated. Some modifications of the CK classifications are sketched, including elongation of the CK blueprint, fusion of two CK blueprints, dodecahedral view of the CK shapes, and generalized CK designs without a clearly visible geometry of the icosahedron. These are compared to cases of existing viruses.
A Review of the Exceptional Supersymmetric Standard Model
Authors: King Stephen F. , Moretti Stefano , Nevzorov Roman
Published: April 2020

Local supersymmetry (SUSY) provides an attractive framework for the incorporation of gravity and unification of gauge interactions within Grand Unified Theories (GUTs). Its breakdown can lead to a variety of models with softly broken SUSY at low energies. In this review article, we focus on the SUSY extension of the Standard Model (SM) with an extra U ( 1 ) N gauge symmetry originating from a string-inspired E 6 GUTs. Only in this U ( 1 ) extension of the minimal supersymmetric standard model (MSSM) can the right-handed neutrinos be superheavy, providing a mechanism for the baryon asymmetry generation. The particle content of this exceptional supersymmetric standard model (E 6 SSM) includes three 27 representations of the E 6 group, to ensure anomaly cancellation. In addition it also contains a pair of S U ( 2 ) W doublets as required for the unification of gauge couplings. Thus, E 6 SSM involves exotic matter beyond the MSSM. We consider symmetries that permit suppressing flavor changing processes and rapid proton decay, as well as gauge coupling unification, the gauge symmetry breaking and the spectrum of Higgs bosons in this model. The possible Large Hadron Collider (LHC) signatures caused by the presence of exotic states are also discussed.
Handling Covariates in Markovian Models with a Mixture Transition Distribution Based Approach
Authors: Bolano Danilo
Published: April 2020

This paper presents and discusses the use of a Mixture Transition Distribution-like model (MTD) to account for covariates in Markovian models. The MTD was introduced in 1985 by Raftery as an approximation of higher order Markov chains. In the MTD, each lag is estimated separately using an additive model, which introduces a kind of symmetrical relationship between the past and the present. Here, using an MTD-based approach, we consider each covariate separately, and we combine the effects of the lags and of the covariates by means of a mixture model. This approach has three main advantages. First, no modification of the estimation procedure is needed. Second, it is parsimonious in terms of freely estimated parameters. Third, the weight parameters of the mixture can be used as an indication of the relevance of the covariate in explaining the time dependence between states. An illustrative example taken from life course studies using a 3-state hidden Markov model and a covariate with three levels shows how to interpret the results of such models.
Using Data Envelopment Analysis and Multi-Criteria Decision-Making Methods to Evaluate Teacher Performance in Higher Education
Authors: Popović Milena , Savić Gordana , Kuzmanović Marija , Martić Milan
Published: April 2020

This paper proposes an approach that combines data envelopment analysis (DEA) with the analytic hierarchy process (AHP) and conjoint analysis, as multi-criteria decision-making methods to evaluate teachers’ performance in higher education. This process of evaluation is complex as it involves consideration of both objective and subjective efficiency assessments. The efficiency evaluation in the presence of multiple different criteria is done by DEA and results heavily depend on their selection, values, and the weights assigned to them. Objective efficiency evaluation is data-driven, while the subjective efficiency relies on values of subjective criteria usually captured throughout the survey. The conjoint analysis helps with the selection and determining the relative importance of such criteria, based on stakeholder preferences, obtained as an evaluation of experimentally designed hypothetical profiles. An efficient experimental design can be either symmetric or asymmetric depending on the structure of criteria covered by the study. Obtained importance might be a guideline for selecting adequate input and output criteria in the DEA model when assessing teachers’ subjective efficiency. Another reason to use conjoint preferences is to set a basis for weight restrictions in DEA and consequently to increase its discrimination power. Finally, the overall teacher’s efficiency is an AHP aggregation of subjective and objective teaching and research efficiency scores. Given the growing competition in the field of education, a higher level of responsibility and commitment is expected, and it is therefore helpful to identify weaknesses so that they can be addressed. Therefore, the evaluation of teachers’ efficiency at the University of Belgrade, Faculty of Organizational Sciences illustrates the usage of the proposed approach. As results, relatively efficient and inefficient teachers were identified, the reasons and aspects of their inefficiency were discovered, and rankings were made.
Vision/Position Hybrid Control for a Hexa Robot Using Bacterial Foraging Optimization in Real-time Pose Adjustment
Authors: Huynh Ba-Phuc , Su Shun-Feng , Kuo Yong-Lin
Published: April 2020

This paper presents a novel architecture of the vision/position hybrid control for a Hexa parallel robot. The 3D vision system is combined with the Proportional-Integral-Derivative (PID) position controller to form a two-level closed-loop controller of the robot. The 3D vision system measures the pose of the end-effector after the PID control. The measurement of the 3D vision system is used as a feedback of the second closed-loop control. The 3D vision system has a simple structure using two fixed symmetric cameras at the top of the robot and four planar colored markers on the surface of the end-effector. The 3D vision system detects and reconstructs the 3D coordinates of colored markers. Based on the distance and coplanarity constraints of the colored markers, the optimization problem is modeled for the real-time adjustment, which is implemented during the operation of the robot to minimize the measurement error of the 3D vision system due to both the initial calibration of the stereo camera and the external noise affecting image processing. The bacterial foraging optimization is appropriately configured to solve the optimization problem. The experiment is performed on a specific Hexa parallel robot to assess the effectiveness and feasibility of the proposed real-time adjustment using the bacterial foraging optimization. The experimental result shows that it has high accuracy and fast computation time although the experiment is conducted on a laptop with an average hardware configuration. An experimental comparison of the performance between the proposed method and another control method is also implemented. The results show the superiority and application potential of the proposed method.

Authors: Guerreiro Rafael , Pires Tiago , Guedes José M. , Fernandes Paulo R. , Castro André P. G.
Published: April 2020

Recently, bone tissue engineering (TE) has seen new developments, with triply periodic minimal surfaces (TPMSs) being used to develop new porosity-controlled scaffolds to interface new tissue growth. The process of choosing the best geometry to a specific application still lacks research, so the goal for this work is to propose a new method of scaffold selection, based on assessing the tortuosity inside these symmetric TPMS-based structures. Additionally, computer fluid dynamic (CFD) simulations were conducted to validate this method. The comparison between tortuosity and CFD outputs suggests that an analysis of the tortuosity could be used as an early indicator of the scaffold’s viability for specific applications, favouring scaffolds with more intricate and curvature-dependent streamlines.

Published: April 2020

Increasing the number of threats against software vulnerabilities and rapidly growing data breaches have become a key concern for both the IT industry and stakeholders. Developing secure software systems when there is a high demand for software products from individuals as well as the organizations is in itself a big challenge for the designers and developers. Meanwhile, adopting traditional and informal learnings to address security issues of software products has made it easier for cyber-criminals to expose software vulnerabilities. Hence, it is imperative for the security practitioners to employ a symmetric mechanism so as to achieve the desired level of software security. In this context, a decision-making approach is the most symmetrical technique to assess the security of software in security tactics perspective. Since the security tactics directly address the quality attribute concerns, this symmetric approach will be highly effective in making the software systems more secure. In this study, the authors have selected three main attributes and fifteen sub-attributes at level 1 and level 2, respectively, with ten different software of an institute as alternatives. Furthermore, this study uses a fuzzy-based symmetrical decision-making approach to assess the security of software with respect to tactics. Fuzzy Analytic Network Process (F-ANP) is applied to evaluate the weights of criteria and fuzzy-Symmetrical technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) is used to determine impact of alternatives. The proposed symmetrical assessment in this study will be beneficial for both the designers and developers to categorize and prioritize the security attributes and understand the importance of security tactics during software development life cycle.

Published: April 2020

RNA granules and exosomes produced by tumour cells under various stresses in the microenvironment act as critical determinants of cell survival by promoting angiogenesis, cancer metastasis, chemoresistance, and immunosuppression. Meanwhile, developmental cancer/testis (CT) antigens that are normally sequestered in male germ cells of the testes, but which are overexpressed in malignant tumour cells, can function as tumour antigens triggering immune responses. As CT antigens are potential vaccine candidates for use in cancer immunotherapy, they could be targeted together with crosstalk between stress granules, exosomes, and immune cells for a synergistic effect. In this review, we describe the effects of exosomes and exosomal components presented to the recipient cells under different types of stresses on immune cells and cancer progression. Furthermore, we discuss their significance for cancer immunity, as well as the outlook for their future application.

Authors: Obeidat Belal
Published: April 2020

Twenty-four Awassi lambs were randomly divided into two dietary treatments to assess the influence of black cumin meal (BCM; Nigella sativa L.) feeding on growth performance. Diets were no BCM (CON) or 150 g BCM/kg DM (BCM150)). Lambs were fed the experimental diets for 80 days. Lambs were housed randomly in individual pens that were fitted with water and feed containers. During the study, nutrient intake was measured daily. Body weight (BW) and average daily gain (ADG) were evaluated biweekly. Nutrient digestibility and nitrogen (N) balance were evaluated on days 49–59. Intakes of dry matter, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE) and metabolizable energy were greater (p ≤ 0.05) in the BCM150 diet than in the CON diet. The digestibility of DM, CP and EE (p ≤ 0.04) was improved in the BCM150 diet compared to the CON diet. However, NDF and ADF digestibility did not differ between the two diets. Nitrogen retained (g/d; p = 0.01) and N retention (%; p = 0.05) was greater in the BCM150 compared with CON diet. Final BW, ADG, and feed efficiency (DM intake: kg of gain) was greater (p ≤ 0.002) in BCM150 lambs than the CON lambs. However, cost/kg of BW gain was lower in the BCM150 diet than in the CON diet. In conclusion, the inclusion of black cumin meal improved the growth performance and profits in diets of growing lambs. Therefore, it could be used as an alternative to soybean meal and barley as a protein and energy supplement, respectively.

Published: April 2020

Background: In Ethiopia, improvement and innovation of the emergency care system is hindered by lack of specialist doctors trained in emergency medicine, underdeveloped emergency care infrastructure, and consumable resource limitations. Our aim was to examine the critical factors affecting retention of graduates from the Addis Ababa University (AAU) post-graduate emergency medicine (EM) training program within the Ethiopian health care system. Methods: Qualitative interviews were conducted with current AAU EM residents and stakeholders in Ethiopian EM. Mixed-methods inductive thematic analysis was performed.Results: Resident and stakeholder participants identified critical factors in three domains: the individual condition, the occupational environment, and the national context. Within each domain, priority themes emerged from the responses, including the importance of career satisfaction over the career continuum (individual condition), the opportunity to be involved in the developing EM program and challenges associated with resource, economic, and employment constraints (occupational environment), and perceptions regarding the state of awareness of EM and the capacity for change at the societal level (national context). Conclusions: This work underscores the need to resolve multiple systemic and cultural issues within the Ethiopian health care landscape in order to address EM graduate retention. It also highlights the potential success of a retention strategy focused on the career ambitions of keen EM doctors.

A Point of Care Lateral Flow Assay for Rapid and Colorimetric Detection of Interleukin 6 and Perspectives in Bedside Diagnostics
Authors: Eiras Carla
Published: April 2020

Interleukin-6 (IL-6) is a multifunctional cytokine and high bloodstream levels of which have been associated with severe inflammatory diseases, such as dengue fever, sepsis, various cancers, and visceral leishmaniasis (VL). Rapid tests for the quantification of IL-6 would be of great assistance for the bedside diagnosis and treatment of diseases such as VL. We have developed a lateral flow assay (LFA) for rapid and colorimetric IL-6 detection, consisting of anti-IL-6 antibodies conjugated to gold nanoparticles (AuNPs). The optimal concentration of anti-IL-6 used in the conjugate was determined to be 800.0 μg/mL, based on an aggregation assay using LFA. A linear relationship between IL-6 standard concentration and color intensity was observed after 20 min, with a linear range between 1.25 ng/mL and 9,000 ng/mL. The limit of detection for this method was estimated at a t0.38 ng/mL. The concentration of IL-6 in five patients with severe VL was measured using LFA, and the results were consistent with those obtained using the cytometric bead array (CBA) method. A thorough analysis of the LFA membranes’ surface morphology, before and after sample contact, was performed using atomic force microscopy (AFM). The prototype described here is still being tested and improved, but this LFA will undoubtedly be of great help in the clinical quantification of IL-6.

In the environment where we live or where we carry out economic activities, we often find that business activities carried out by a person or a certain business group often ignore the ethics in conducting their activities. Many deviations are made in line with the purpose of doing business activities only to achieve maximum profits without providing a comfort effect for workers. Many of the few business people we meet may not pay attention to their employees, especially in maintaining work safety and safety or easily usually abbreviated as K3 (occupational safety and health). For this reason, every business person needs to pay attention to the role of business ethics in occupational safety and health. With the implementation of the occupational safety and health management system (K3), the company has carried out ethics or is responsible for the worst possibilities that occur as a result of work activities. The image of companies that have implemented occupational safety and health management (K3) will get a positive assessment from the community so that they can compete in the global era

Considering the multivalent role of interleukin-6 (IL-6) both in rheumatoid arthritis (RA) and in the metabolic processes, we aimed to evaluate the positive effect of subcutaneous tocilizumab (TCZ) on the probability of developing diabetes mellitus (DM). We recruited 56 consecutive patients with definite and active RA and assessed demographics, RA-related parameters and metabolic biomarkers, including the Homeostasis Model Assessment for insulin resistance (HOMA-IR) and the Quantitative Insulin Sensitivity Check Index (QUICKI). After 52 weeks of treatment, most of the patients showed a statistically significant reduction of HOMA-IR (3.61 � 1.21 at baseline vs. 2.45 � 1.46 at the end of the study, p[0.001), while QUICKI registered only a slight increase (0.32 � 0.01 at baseline vs. 0.33 � 0.01 at final evaluation, p[0.001). Our results strongly suggest that long-term IL-6 blockade has a beneficial effect in slowing the atherosclerotic process and reducing CV risk in active RA.

The fourth generation cephalosporin antibacterial agent, cefepime, was loaded into layered double hydroxides for enhancing antibiotic efficiency, reducing side effects, as well as achieving the sustained release property. The intercalation of antibiotic into the inter-gallery of ZnAl-layered double hydroxide (LDH) was carried out using ion exchange method, by this constituting a nano-sized organic-inorganic hybrid material for a controlled release novel formulation. Although cefepime is a broad spectrum antibiotic, it has various adverse effects and a significant degradation rate. Thus, the preparation and physico-chemical characterization of nanomaterials able to intercalate this drug is an important study for medical and pharmaceutical field. The antibiotic inclusion into LDHs nanostructure was confirmed by advanced characterization techniques and the release profile of cefepime was analysed with the respect to pH of the simulated media.

Published: April 2020

This paper describes the current diagnostic methods of Chronic Wasting Disease (CWD) in cervides used between 2013 and 2017 in Romania. The active surveillance of CWD involves the targeted groups screening by using rapid diagnostic tests (e.g., antigen capture enzyme immunoassay). If the first test does not provide certain negative results, then the confirmatory methods have been used, i.e. histopathology, immunohistochemistry and Western immunoblotting. These tests did not lead to the detection of CWD prions (PrPCWD) in Romania. This may be due to the absence or insufficient quantity of PrPCWD in samples, below the threshold of confirmatory tests.

Clostridium difficile infection has increased over the past decades. Surgical patients, especially those undergoing intestinal surgery, have higher rates of this infection. Patients infected with Clostridium difficile are more likely to have postoperative complications and higher rates of mortality. We will present the results of a retrospective study made in the 2nd clinic of Surgery at the Clinical Emergency County Hospital �Sf. Ap. Andrei� Galati. This study includes 431 patients with complicated colorectal cancers operated in emergency between 2007 and 2016. All the patients infected with Clostridium difficile received oral Metronidazole. Only one of the infected patients presented a recurrence which was treated with oral vancomycin. The treatment of Clostridium difficile infection has become a global public health challenge. Colorectal surgery is a documented risk factor for Clostridium difficile infection. The prevalence of Clostridium difficile infection has grown in the last years and this increase has been particularly apparent among surgical patients. In a large intestine weakened by cancer, the risk of this infection can increase even more. New strategies to prevent the Clostridium difficile infection are required.

En el presente estudio, se prepararon nuevos biosorbentes basados en compósitos de magnetita (Fe3 O4 ), hidroxiapatita (HAp) y nanotubos de carbono de pared múltiple (MWCNT). Los materiales preparados fueron caracterizados mediante técnicas de dispersión dinámica de luz (DLS) espectroscopía infrarroja (FTIR), microscopía electrónica de barrido (SEM), magnetometría de muestra vibrante (VSM), espectroscopía Raman y voltamperometría de onda cuadrada. La magnetita sintetizada presentó un comportamiento ferromagnético. La HAp tuvo menor tamaño mediante la síntesis hidrotermal. Además, se evaluó el posible uso del compósito que involucraba a los tres materiales de partida (Fe3 O4 /MWCNT/HAp) en la remoción de un metal pesado como As(V) en solución acuosa, teniendo en cuenta la influencia de factores como pH, masa de adsorbente y tiempo de contacto. Se obtuvo los valores máximos de porcentaje de remoción de este metal (mayor a 85 %) a condiciones de pH 6, dosis de adsorbente de 0,5 g L-1 y un tiempo de contacto de 2 h.
Mapping of Hazards to Karst Groundwater on the Velika Planina Plateau
Authors: Kovačič Gregor , Ravbar Nataša
Published: April 2020

Prispevek obravnava kartiranje onesnaževalcev podtalnice na alpski kraški planoti Velika planina. Kljub temu, da na planoti ni stalne poselitve, je kakovost vode v izvirih pod planoto ogrožena zaradi športne, turistične in živinorejske aktivnosti na planoti. V izvirih so že zabeležili onesnaženje, kar kaže na pomanjkljivosti upravljanja s pitno vodo tudi na neposeljenih območjih alpskega krasa, ki so sicer z vidika varovanja zelo primerna za zaščito.  The present paper presents the hazard mapping of groundwater on the Velika planina alpine karst plateau. There are no permanent residents on the plateau. Nevertheless, some serious hazards to the quality of the respective karst springs are arising from sports, tourist and farming activities. Some pollution has been already recorded in springs, showing the shortcomings of drinking water management also in uninhabited alpine karst areas, which are ordinarily very favourable for water protection.

Nekaj primerov paronomazije med slovenščino in furlanščino v furlanskih toponimih
Authors: Puntin Maurizio
Published: April 2020

Avtor obravnava 11 primerov paronomazije s historičnega območja Furlanije, zlasti z njenega najbolj zanimivega vzhodnega dela. Tu je več kot tisočletni stik med slovenskimi in romanskimi (furlanskimi) narečji sprožil prevzeme, kalkiranja, paretimologijo (in druge procese), ki jih je potrebno proučevati od primera do primera, od območja do območja, saj ima vsako območje svojo zgodovino, ki omogoča razložiti posamezne jezikovne pojave.

Primerjava slovarske predstavitve frazemov v hrvaškem/srbskem in češkem enojezičnem razlagalnem frazeološkem slovarju
Authors: Gantar Polona
Published: April 2020

S primerjalno analizo vrstno, jezikovno in časovno sorodnih slovarjev je mogoče ugotoviti različne načine leksikografske predstavitve frazemov, zlasti glede razvrstitve in zasnove iztočnic, označevanja oblik rabe, frazeoloških variant inpretvorbenih omejitev, predstavitve obveznih vezljivostnih določil ter stilistične in slovnične obdelave. Bistvena razhajanja v predstavitvi frazeoloških enot temeljijo predvsem na izbiri predstavitvene ravni (sistem — realizacija), namembnosti (strokovni - nestrokovni uporabnik) in definiciji frazeološke enote.

L’urbanité, c’est là et ça va donner
Authors: Jeanneret Yves
Published: April 2020

L’article aborde les images de la ville par la manière dont les dispositifs de représentation sont affectés par les motifs de la trace et de la donnée. Après une discussion du concept de représentation chez Louis Marin, ces motifs sont approchés comme figures privilégiées d’un chronotope médiatique. La donnée est liée à une naturalisation (c’est là) et à une relation inchoative au temps (ça va donner). La dernière partie de la contribution décrit les multiples médiations de ce chronotope de la ville, producteur d’une certaine conception de l’urbanité, à propos d’un projet institutionnel, d’un dispositif expérimental et d’un ouvrage publié portant tous trois sur le projet de créer une ville intelligente (smart city).
Educating Highly Able Students from an African Perspective
Authors: Ngara Constantine
Published: April 2020

Basing on Cabral's (1973) legendary practical wisdom to return to the source, in the quest to broaden existing understanding of giftedness and improve the education of gifted students, the chapter examines indigenous conceptions of giftedness espoused in Bantu cultures of southern Africa. As informed by insights gleaned from research on Ndebele, Shona and Vhenda cultures' views of giftedness, indigenous cultures' views warrant attention as they promise to enrich the education of gifted students in amazing and intriguing ways. The chapter offers specific recommendations for educating highly able students including a Dynamic and Interactive Process Model of Talent development (DIPM) grounded in indigenous cultures of southern Africa currently generating interest in gifted education.
A Feasibility Study of Methodological Issues and Short-Term Outcomes in Seriously Injured Older Adults
Authors: Richmond Therese S. , Thompson Hilaire J. , Kauder Donald , Robinson Keith M. , Strumpf Neville E.
Published: April 2020

• Background For any given traumatic injury, older adults experience a longer hospitalization, more complications, and higher mortality than do younger patients.

• Objectives To prospectively identify problems in designing follow-up studies in seriously injured older adults without head injury and to examine outcomes after serious trauma in older adults who were sent to a level I trauma center.

• Methods A short-term descriptive follow-up design was used in which each patient served as his or her baseline. Eligible patients had injuries that required admission to an intensive care unit, a hospital length of stay longer than 72 hours, or surgery. Patients with isolated hip fractures, central nervous system injuries, and burn injuries were excluded. Data were collected by using standardized instruments during the acute hospital stay and 3 months after discharge from the hospital.

• ResultsDuring a representative 2-month period, 21% of a potential 77 subjects died in the hospital, 44% had cognitive impairment that precluded participation, and 17% declined to participate. Twenty older adults (mean age 73.5 years) who were injured in motor vehicle crashes (45%), falls (35%), or pedestrian accidents (15%) or who had gunshot wounds (5%) were enrolled. Ten percent died after discharge. Levels of physical disability at 3 months after discharge were higher than those before the injury (score on Sickness Impact Profile physical subscale 24.5 vs 10.9, P = .02), and psychological distress (Impact of Event Scale score 20.9) remained elevated.

• Conclusion Mortality, disability, and posttraumatic psychological distress after discharge are problems in seriously injured older adults.
Emancipações distritais e o grau de desenvolvimento humano municipal em Minas Gerais
Authors: Nunes Marcos Antônio , Lobo Carlos Fernando Ferreira , Garcia Ricardo Alexandrino
Published: April 2020

Após a aprovação da Constituição Federal de 1988, verificou-se no Brasil uma corrida emancipacionista distrital em quase todas as unidades federativas. Em Minas Gerais foram mais de cem municípios criados. Para aferir o grau de sucesso das emancipações mineiras, utilizou-se o Índice de Desenvolvimento Humano Municipal (IDH-M) referente aos anos de 2000 e 2010, distribuídos conforme mesorregião geográfica. Observou-se, no período em análise, que em vários municípios recém-criados o nível de desenvolvimento humano não apresentou diferenciações das condições experimentadas pelos municípios-mãe (de origem). Em alguns, os municípios recém-criados apresentaram queda no nível de desenvolvimento em relação aos municípios-mãe.
