The literature indicates that the limited pharmacovigilance knowledge demonstrated by healthcare professionals is the main reason for the underreporting of adverse drug reactions. Therefore, the main objective of this study was to investigate pharmacy, dental and medical students’ knowledge and attitudes to pharmacovigilance and pharmacovigilance education. The cross-sectional questionnaire study was conducted at the University of Split School of Medicine in November 2020. In total, 350 students participated in the study. The results have shown that pharmacy students showed a significantly higher knowledge score compared to dental and medical students (P < 0.001). In total 92.2% of pharmacy, 21.8% of dental and 70.8% of medical students had knowledge of patients’ involvement in adverse drug reactions, reporting (P < 0.001). Interestingly, only 44.3% of all students knew that adverse drug reactions could be reported using a mobile application. Moreover, significantly more pharmacy students (74.4%) were aware of the adverse drug reactions monitoring center in Croatia, with 47.5% of dental and 39.2% of medical students correctly identifying it (P < 0.001). The results showed that most students felt that pharmacovigilance was not adequately covered in curricula; therefore, there is a great need to increase the knowledge and awareness of pharmacovigilance among students aspiring to become future healthcare professionals, and improve their reporting practice in clinical future.

Authors: Dembskey Nadia , Abrahamse Heidi
Published: August 2021

(1) Background: Onychomycosis accounts for 50% of nail pathologies and is a therapeutic challenge due to an increase in resistance to antifungal agents. This study aimed to explore the effectiveness of 1064 nm diode laser irradiation for the treatment of Onychomycosis and establish a new set of laser parameters for effective and safe treatment; (2) Methods: An exploratory, single-blinded study was conducted on forty-five patients with toenail Onychomycosis. Digital images and nail clippings were taken for Periodic Acid-Schiff (PAS) staining and fungal microscopy and culture (MC&S). Group 1 received 5% topical Amorolfine lacquer to apply to affected nails. Group 2 received 1064 nm diode laser treatment at 10 mW/s, hallux 790 J/cm2 and lesser digits 390 J/cm2 (standard treatment). Group 3 received 1064 nm diode laser treatment at 10 mW/s, hallux 1 100 J/cm2 and lesser digits 500 J/cm2 (new treatment parameters). After laser treatment, nail temperatures were taken with a surface thermometer; (3) Results: PAS staining was more sensitive in identifying Onychomycosis (91.1%), compared to Fungal Microscopy (44.4%). Comparing treatment requirements over a period of 24 weeks, there was a statistical significance, p ≤ 0.01 (**), for standard laser treatment and, p ≤ 0.001 (***), for new laser parameter treatment, indicating treatment needed over time decreased. No adverse effects were noted with new laser therapy. An 86.7% visual improvement was noted in Group 3 after 24 weeks; (4) Conclusions: Phototherapy, or photo thermolysis, was the best treatment option for Onychomycosis. A new protocol for the standardization of laser irradiation with the possible inclusion into the Scoring Clinical Index for Onychomycosis treatment plan, was proposed.

Antibiotics, nowadays, are not only used for the treatment of human diseases but also used in animal and poultry farming to increase production. Overuse of antibiotics leads to their circulation in the food chain due to unmanaged discharge. These circulating antibiotics and their residues are a major cause of antimicrobial resistance (AMR), so comprehensive and multifaceted measures aligning with the One Health approach are crucial to curb the emergence and dissemination of antibiotic resistance through the food chain. Different chromatographic techniques and capillary electrophoresis (CE) are being widely used for the separation and detection of antibiotics and their residues from food samples. However, the matrix present in food samples interferes with the proper detection of the antibiotics, which are present in trace concentrations. This review is focused on the scientific literature published in the last decade devoted to the detection of antibiotics in food products. Various extraction methods are employed for the enrichment of antibiotics from a wide variety of food samples; however, solid-phase extraction (SPE) techniques are often used for the extraction of antibiotics from food products and biological samples. In addition, this review has scrutinized how changing instrumental composition, organization, and working parameters in the chromatography and CE can greatly impact the identification and quantification of antibiotic residues. This review also summarized recent advancements in other detection methods such as immunological assays, surface-enhanced Raman spectroscopy (SERS)-based assays, and biosensors which have emerged as rapid, sensitive, and selective tools for accurate detection and quantification of traces of antibiotics.
Influence of Leachate and Nitrifying Bacteria on Photosynthetic Biogas Upgrading in a Two-Stage System
Authors: Saldarriaga Luis Fernando , Almenglo Fernando , Cantero Domingo , Ramírez Martín
Published: August 2021

Photosynthetic biogas upgrading using two-stage systems allows the absorption of carbon dioxide (CO2) in an absorption unit and its subsequent assimilation by microalgae. The production of microalgae requires large amounts of nutrients, thus making scale-up difficult and reducing economic feasibility. The photosynthetic process produces oxygen (O2) (1 mol per mol of CO2 consumed), which can be desorbed into purified biogas. Two-stage systems reduce its impact but do not eliminate it. In this study, we test the use of landfill leachate as a nutrient source and propose a viable and economical strategy for reducing the O2 concentration. First, the liquid/gas (L/G) ratio and flow mode of the absorber were optimized for 20% and 40% CO2 with COMBO medium, then landfill leachate was used as a nutrient source. Finally, the system was inoculated with nitrifying bacteria. Leachate was found to be suitable as a nutrient source and to result in a significant improvement in CO2 absorption, with outlet concentrations of 0.01% and 0.6% for 20% and 40% CO2, respectively, being obtained. The use of nitrifying bacteria allowed a reduction in dissolved oxygen (DO) concentration, although it also resulted in a lower pH, thus making CO2 uptake slightly more difficult.
DBSCAN-Based Tracklet Association Annealer for Advanced Multi-Object Tracking
Authors: Kim Jongwon , Cho Jeongho
Published: August 2021

Recently, as the demand for technological advancement in the field of autonomous driving and smart video surveillance is gradually increasing, considerable progress in multi-object tracking using deep neural networks has been achieved, and its application field is also expanding. However, various problems have not been fully addressed owing to the inherent limitations in video cameras, such as the tracking of objects in an occluded environment. Therefore, in this study, we propose a density-based object tracking technique redesigned based on DBSCAN, which has high robustness against noise and is excellent for nonlinear clustering. Moreover, it improves the noise vulnerability inherent to multi-object tracking, reduces the difficulty of trajectory separation, and facilitates real-time processing through simple structural expansion. Through performance test evaluation, it was confirmed that by using the proposed technique, several performance indices were improved compared to the existing tracking technique. In particular, when added as a post processor to the existing tracker, the tracking performance owing to noise suppression was considerably improved by more than 10%. Thus, the proposed method can be applied in industrial environments, such as real pedestrian analysis and surveillance security systems.
Robust Measurement-Driven Cardinality Balance Multi-Target Multi-Bernoulli Filter
Authors: Yang Biao , Zhu Shengqi , He Xiongpeng , Yu Kun , Zhu Jingjing
Published: August 2021

The multi-target tracking filter under the Bayesian framework has strict requirements on the prior information of the target, such as detection probability density, clutter density, and target initial position information. This paper proposes a novel robust measurement-driven cardinality balance multi-target multi-Bernoulli filter (RMD-CBMeMBer) for solving the multiple targets tracking problem when the detection probability density is unknown, the background clutter density is unknown, and the target’s prior position information is lacking. In RMD-CBMeMBer filtering, the target state is first extended, so that the extended target state includes detection probability, kernel state, and indicators of target and clutter. Secondly, the detection probability is modeled as a Beta distribution, and the clutter is modeled as a clutter generator that is independent of each other and obeys the Poisson distribution. Then, the detection probability, kernel state, and clutter density are jointly estimated through filtering. In addition, the correlation function (CF) is proposed for creating new Bernoulli component (BC) by using the measurement information at the previous moment. Numerical experiments have verified that the RMD-CBMeMBer filter can solve the multi-target tracking problem under the condition of unknown target detection probability, unknown background clutter density and inadequate prior position information of the target. It can effectively estimate the target detection probability and the clutter density.

Published: August 2021

The emergence of various types of commercial cameras (compact, high resolution, high angle of view, high speed, and high dynamic range, etc.) has contributed significantly to the understanding of human activities. By taking advantage of the characteristic of a high angle of view, this paper demonstrates a system that recognizes micro-behaviors and a small group discussion with a single 360 degree camera towards quantified meeting analysis. We propose a method that recognizes speaking and nodding, which have often been overlooked in existing research, from a video stream of face images and a random forest classifier. The proposed approach was evaluated on our three datasets. In order to create the first and the second datasets, we asked participants to meet physically: 16 sets of five minutes data from 21 unique participants and seven sets of 10 min meeting data from 12 unique participants. The experimental results showed that our approach could detect speaking and nodding with a macro average f1-score of 67.9% in a 10-fold random split cross-validation and a macro average f1-score of 62.5% in a leave-one-participant-out cross-validation. By considering the increased demand for an online meeting due to the COVID-19 pandemic, we also record faces on a screen that are captured by web cameras as the third dataset and discussed the potential and challenges of applying our ideas to virtual video conferences.
Research on Energy Efficiency of NOMA–SWIPT Cooperative Relay Network Using GS-DinkelBach Algorithm
Authors: Zhou Ninghao , Hu Jinfeng , Hou Jia
Published: August 2021

In order to improve the energy efficiency (EE) performance of cooperative networks, this study combines non-orthogonal multiple access (NOMA) with simultaneous wireless information and power transfer (SWIPT) technologies to construct a cooperative relay network composed of one base station (BS), multiple near users, and one far user. Based on the network characteristics, a time-division resource allocation rule is proposed, and EE formulas regarding direct-link mode and cooperative mode are derived. Considering user selection and decoding performance, to obtain the optimal EE, this study utilizes a DinkelBach iterative algorithm based on the golden section (GS-DinkelBach) to solve the EE optimization problem, which is affected by power transmitted from the BS, achievable rates under three communication links, and quality of service (QoS) constraints of users. The simulation results show that the GS-DinkelBach algorithm can obtain precise EE gains with low computational complexity. Compared with the traditional NOMA–SWIPT direct-link network model and the relay network model, the optimal EE of the established network model could be increased by 0.54 dB and 1.66 dB, respectively.
A Novel Approach to Automated 3D Spalling Defects Inspection in Railway Tunnel Linings Using Laser Intensity and Depth Information
Authors: Zhou Mingliang , Cheng Wen , Huang Hongwei , Chen Jiayao
Published: August 2021

The detection of concrete spalling is critical for tunnel inspectors to assess structural risks and guarantee the daily operation of the railway tunnel. However, traditional spalling detection methods mostly rely on visual inspection or camera images taken manually, which are inefficient and unreliable. In this study, an integrated approach based on laser intensity and depth features is proposed for the automated detection and quantification of concrete spalling. The Railway Tunnel Spalling Defects (RTSD) database, containing intensity images and depth images of the tunnel linings, is established via mobile laser scanning (MLS), and the Spalling Intensity Depurator Network (SIDNet) model is proposed for automatic extraction of the concrete spalling features. The proposed model is trained, validated and tested on the established RSTD dataset with impressive results. Comparison with several other spalling detection models shows that the proposed model performs better in terms of various indicators such as MPA (0.985) and MIoU (0.925). The extra depth information obtained from MLS allows for the accurate evaluation of the volume of detected spalling defects, which is beyond the reach of traditional methods. In addition, a triangulation mesh method is implemented to reconstruct the 3D tunnel lining model and visualize the 3D inspection results. As a result, a 3D inspection report can be outputted automatically containing quantified spalling defect information along with relevant spatial coordinates. The proposed approach has been conducted on several railway tunnels in Yunnan province, China and the experimental results have proved its validity and feasibility.

Published: August 2021

This paper is aimed at the characterization and manufacturing of an SMA coaxial fed compact blade antenna with dual frequency characteristics for broadband applications on board of Unmanned Air Vehicles (UAVs). This antenna is linearly polarized, and it combines the benefits of Automatic Dependent Surveillance-Broadcast (ADS-B) and 5th Generation (5G) communications in one single element, covering both the 1.030–1.090 GHz and the 3.4–3.8 GHz bands thanks to a bent side and a ‘C’ shaped slot within the radiation element. Starting from the simulation outcomes on an ideal ground plane, the results are here extended to a bent ground plane and on two UAV commercial CAD models. Details of manufacturing of the antenna in both aluminium and FR-4 substrate materials are presented. The comparison between measurements and simulations is discussed in terms of return loss, bandwidth, gain, and radiation pattern. Results show an antenna with a low profile and a simple structure that can be employed in various wideband communication systems, suiting future UAV assisted 5G networks while being perfectly compliant with forthcoming ADS-B based Detect-And-Avoid (DAA) technologies in Unmanned Aerial Traffic Management (UTM).

Published: August 2021

Nuclear power forms part of the first-year physics undergraduate course work in the extended curriculum program at the University of the Western Cape. This investigation intends to assist students in mastering their understanding of how nuclear power works through the development of critical thinking skills around the topic and to create awareness among students of the implications of expanding a nuclear power footprint. Through debate, students in this course investigate the impact of South Africa increasing its nuclear footprint within a global context. In this work, students were encouraged to explore publications and reputable websites surrounding this topic and based on their findings formulate arguments. The authors conceptualized and developed a Sakai tool (based on Learning Tools Interoperability), called Reference Register (RR) to compliment the work. RR stores the reference uploaded by each student, shares uploaded literature resources to the group members, and quantifies the number of times a student uses a reference when presenting their argument. The incorporation of the RR was intended to encourage students to formulate arguments based on well-founded literature. Authors sort to investigate in which ways and to what extent does an online discussion forum facilitate students becoming ethically, environmentally, and socially aware in the area of nuclear energy and to assist students in becoming better in their professional communication skills. The outcome of this student engagement included students becoming familiar with what constitutes a well-formulated scientific argument based on a literature review, group engagement, becoming aware of South African current affairs regarding nuclear power, and its social and economic impact.

METHODOLOGICAL BASES OF INVESTIGATION OF CORRUPTION CRIMES COMMITTED BY TRAFFIC POLICE OFFICERS
Authors: Tsybulsky V.V.
Published: August 2021

Corruption crimes committed by traffic police officers have features that distinguish them from other corruption crimes. These features are important for solving the issue of effective detection and investigation of crimes of this type. At the same time, special attention in the investigation should be paid to how traffic police officers use official powers granted to them by law, as well as to what subjective rights are granted as a result of their abuse of these powers. It is noteworthy that the official powers act in the course of committing corruption crimes by traffic police officers as a means of crime, as well as in some cases as an incentive to commit a specific crime of this type. In this regard, already at the initial stage of the investigation, the investigator must be ready to resist the perpetrators of the crime to establish all the circumstances of the crime. In accordance with these features, the private methodology for investigating corruption crimes committed by traffic police officers should include recommendations that take into account the specifics of the commission of these corruption crimes.

In recent years, it is seen that High Voltage Direct Current (HVDC) transmission line systems have come to the fore in the field of energy efficiency in the world. Therefore, it is predicted that analyzing the technological and economic advantages of HVDC transmission line systems will make an important contribution to energy efficiency policies. In this regard, this study aims to examine the technological and economic advantages of HVDC transmission systems through the historical development with applications in Turkey and in the world. In addition to this, it is expected that the evaluation of the effects of energy efficiency on the economy will bring a different perspective to the energy and economic literature. Therefore, it is thought that energy and economic policies for the spread of HVDC transmission line systems worldwide will be essential. The asymmetric distribution of natural energy sources in the world causes energy supply security problems in the countries such as Turkey in terms of high foreign dependence on energy. For this reason, it is necessary to meet the increasing energy demand and increase the existing capacity day by day. Besides, it is important to develop policies for efficient use of energy. HVDC technology is extremely important for a developing country like Turkey. Moreover, it is known that this energy transmission technology has become widespread in developed countries. Thereby, a technical comparison is done for investment costs of the transmission system in Germany. As a result, other than bringing economic benefits with the energy transmission of Turkey through HVDC, it has important potential for making energy transmission possible with her neighbors and European Union countries.

Yenilenebilir enerji kaynaklarının ısı enerjisini veya atık ısı enerjisini kullanarak güç üretmek için en yaygın kullanılanlardan biri Organik Rankine çevrimidir. Trilateral Çevrim ise Organik Rankine çevriminden türbin elemanı yerine genleştirici kullanılması yönüyle ayrılır. Bu çalışmada, Trilateral çevrim - Organik Rankine çevrim ve Organik Rankine çevrim - Organik Rankine çevrim birleşik güç sistemlerinin yapıları incelenerek Engineering Equation Solver (EES) programı yardımı ile termodinamik analizleri yapıldı. Her bir birleşik güç sistem için jeotermal kaynağın ve alt çevrim evaporatörünün farklı sıcaklık değerlerinde sistem performansını maksimum yapan akışkan çiftleri belirlendi ve bu belirlenen akışkan çiftleri kullanan birleşik güç sistemlerinin sonuçları karşılaştırıldı. Araştırma sonuçlarına göre, her bir çalışma şartı için ısıl verimi ve/veya sistemden elde edilen net gücü maksimum yapan akışkan çiftleri olduğu tespit edildi. Jeotermal kaynağın 100-280 oC sıcaklıklarında birleşik güç sisteminin net gücünü maksimum yapan alt çevrim evaporatör sıcaklığının olduğu tespit edildi. Çalışma şartlarına bağlı olarak ORÇ-ORÇ’nin net güç çıktısının TLÇ-ORÇ’ye göre % 23,5’e kadar daha yüksek olduğu belirlendi.

Nowadays, silica aerogels with promising properties have gained interest in many fields.
To enhance properties of the silica aerogels and reduce material cost, many approaches such as preparation of silica aerogels composites using low-cost precursors rich in silica have been developed. In this study, polyethylene glycol (PEG)/silica and carbon black (CB)/silica aerogel composites were easily prepared by sol-gel method. Morphological properties of the composites were investigated by field emission scanning electron microscopy (FESEM) analysis. PEG and CB incorporation improved textural properties of the silica aerogel. Specific surface area of the silica aerogel was increased from 477 m2/g to 541 m2/g and 553 m2/g with the addition of PEG and CB, respectively. Moreover, silica aerogel composites showed higher pore volume and pore size than silica aerogel. It was determined that CB/silica aerogel composite exhibited the highest thermal stability. Thermal conductivity of the silica aerogel (0.035 W/m K) slightly increased with PEG and CB addition highly depending on bulk density. The bulk density of PEG/silica and CB/silica aerogel composites was specified as 0.048 g/cm3 and 0.067 g/cm3, respectively. The obtained results showed that silica aerogel composites with hopeful properties can be used in many applications.

В настоящей статье представлены результаты моделирования способов реализации компьютерных атак на мобильные устройства. Актуальность данной статьи обусловлена отсутствием наработок по формированию методического обеспечения, касающегося моделирования способов реализации компьютерных атак на мобильные устройства, учитывающего их специфику. Предложенные модели способов предназначены для формирования методического обеспечения расчета рисков и выявления оценки защищенности таких систем от актуальных сценариев реализации угроз безопасности информации, которое даёт возможность обоснованного выбора мер защиты. Построение моделей способов реализации компьютерных атак осуществлялось с использованием аппарата сетей Петри на основании сведений, содержащихся в базе данных MITRE ATT&CK. Разработанные модели взаимосвязаны по условиям и последствиям реализации основных технических приёмов, определённых в базе данных ATT&CK и актуальных для мобильных устройств (условия и последствия моделируются позициями сети Петри, а сами технические приёмы - переходами сети Петри). Также в статье затрагиваются вопросы автоматизации и совместной разработки подобных моделей. Проводится сравнительный анализ различных форм представления участков моделируемой сети Петри в контексте удобства процесса её разработки

This article presents the results of modeling methods for implementing computer attacks on mobile devices. The relevance of this article is due to the lack of developments in the formation of methodological support for modeling methods for implementing computer attacks on mobile devices, taking into account their specifics. These models are intended for the formation of methodological support for calculating risks and identifying the assessment of the security of such systems from current scenarios of information security threats, which makes it possible to make an informed choice of security measures. The construction of models of ways to implement computer attacks was carried out using the device of Petri nets based on the information contained in the MITRE ATT&CK database. These models are interconnected by the conditions and consequences of the implementation of the main techniques defined in the ATT&CK database and relevant for mobile devices (conditions and consequences are modeled by the positions of the Petri net, and the techniques themselves are modeled by the transitions of the Petri net). In article also addresses the issues of automation and joint development of such models. A comparative analysis of various forms of representation of the sections of the simulated Petri net in the context of the convenience of its development process is carried out.
