Published: June 2023

Background: Many healthcare and educational institutions have continued to utilise technology-driven learning well before 2020. However, there is limited published literature that rigorously evaluates student outcomes in virtually-delivered advanced pharmacy practice experience (APPE) rotations. This article reports student competency and comfort from eighteen 4th professional year Doctor of Pharmacy students from May 2020 to December 2020.
Methods: Students completed 40 virtual, case-based, clinical reasoning cases during each 6-week APPE. A validated expert-generated anonymous survey was administered to students on two separate occasions. Student competency was assessed using expert-generated case-based clinical questions, and comfort was assessed using a 5-point Likert scale.
Results: Competency scores demonstrated statistically significant improvements in 40% (N=6) of the domains and non-statistically significant improvements in the remaining 60% (N=9). Student comfort improved in 93.33% of the domains but was not statistically significant.
Conclusion: Future directions include exploring the impact of virtual cases in combination with on-ground rotations and comparing student knowledge after graduation.

Secure Software Development Awareness: A Case Study of Undergraduate Developers
Authors: Mutanga Murimo Bethel
Published: June 2023

As ubiquitous computing becomes an increasingly inherent component of everyday life due to the rapid growth of communication technologies and globalization, threats against information systems have taken a more latent yet lethal dimension. This emergent digital security challenge has correspondingly motivated a proactive change in the software engineering process in recent decades. This change has inspired more intense research scrutiny on security as a crucial component of any software system. Moreover, in today’s virtual world of hyperconnectivity, the most significant vulnerabilities in modern information systems security are software centred. Nevertheless, research shows that software developers often lack the required knowledge and skills in secure software systems development (SSD). Such knowledge ensures that all the resultant software components of each development lifecycle are correctly implemented rather than merely following the SSD lifecycle. Also, the knowledge engenders software security consciousness as a professional attitude amongst developers. Therefore, investigating students’ awareness of SSD principles can generate insight into evolving the undergraduate software development curriculum – a path to building future career developers. The study used a voluntary online survey to recruit a sample of 76 undergraduate developers and employed a descriptive approach to data analysis. Among other findings, the study revealed that participants' perception of the threat of software vulnerability impacts their attitude towards security on online and mobile platforms. And that though over 90% of the undergraduate developers took software vulnerability threats either “serious” or “extremely serious”, this disposition did not reflect the depth of their knowledge and experience in SSD.

Published: June 2023

Heavy metal contents in soil from Onda tantalite mining area were studied. Thirty and ten soil samples were collected from the mining area and control site, respectively, using a hand auger. The soil samples were analysed for heavy metals; Cd, Co, Cr, Cu, Fe, Pb, Mn, Ni and Zn using atomic absorption spectrophotometer, AAS. The results obtained showed that the mean concentrations for the respective metals above were 9.38±2.98, 18.25±5.32, 40.29±8.47, 34.40±8.77, 1590.57±403.46, 53.10±11.65, 188.57±41.13, ND and 620.44±91.47 mg/kg in soils from the mining area and 6.40±1.99, 21.00±3.68, ND, 36.36±5.26, 1195.95±314.52, 31.24±6.93, 143.23±28.26, ND and 564.15±120.82 mg/kg for soils from the control site. The mean metal contents from the mining site were all higher than those from the control site due to mining activities, except for Co and Cu but were all lower compared to the recommended permissible limits by WHO except for Cd and Zn. The EF, CF, PLI, ERI and PERI evaluated for metals from the mining site show no imminent danger. However, there is the need for constant and regular monitoring of the level of heavy metals in soil from the site because of accumulation overtime, and soil remediation should be employed to take care of cadmium and zinc.
DESIGN OF A UAV BLADE MONOPOLE WITH THE USE OF DIFFERENT RTADIATING ELEMENTS AND SIMULATION OF DRA ANTENNA
Authors: A. ARVANITIDIS DIMITRIOS , M. MASTRAKOULIS DIMITRIOS , DERVISIS IOANNIS
Published: June 2023

Because of its small size, light weight, and aerodynamic design that causes the least amount of drag blade monopole antennas are favored for usage in airborne applications. Consequently, their radiation patterns are unipolar and produce deep nulls in the upward direction. Such patterns will cause severe blind spots for the aircraft above and below this plane, which is undesirable for avionics networks. [1] To solve this problem, a dielectric resonator antenna (DRA) is attached to the blade antenna and thus a different design is formed. In this paper a rectangular DRA is used to illustrate the main idea.The antenna is housed inside the aerodynamically designed radome to reduce air drag (large dome-shaped structures which protect the radars from the bad weather conditions but at the same time allow the electromagnetic signals to be received by the radar without any distortion or attenuation). [11] An air core coil is also provided for DC grounding proposes. The antenna configuration is first optimized using HFSS based Ansys Electronics Desktop Student 2021 R2 simulation software and latter practically implemented. The comparison of simulated results is also presented in this paper.
Carry-based Differential Power Analysis (CDPA) and its Application to Attacking HMAC-SHA-2

Published: June 2023

In this paper, we introduce Carry-based Differential Power Analysis (CDPA), a novel methodology that allows for attacking schemes that use arithmetical addition. We apply this methodology to attacking HMAC-SHA-2. We provide full mathematical analysis of the method and show that under certain assumptions and with a sufficient amount of traces any key can be revealed. In the experimental part of the paper, we demonstrate successful application of the attack both in software simulation and on an FPGA board using power consumption measurements. With as few as 30K traces measured on the FPGA board, we recover the secrets that allow for forging the HMAC-SHA-2 signature of any message in 3% of the cases — while with 275K traces the success rate reaches 100%. This means that any implementation of HMAC-SHA-2, even in pure parallel hardware, is vulnerable to side-channel attacks, unless it is adequately protected. To the best of our knowledge, this is the first published full-fledged attack on pure hardware implementations of HMAC-SHA-2, which does not require a profiling stage.

In this paper we present the first formally verified implementations of Kyber and, to the best of our knowledge, the first such implementations of any post-quantum cryptosystem. We give a (readable) formal specification of Kyber in the EasyCrypt proof assistant, which is syntactically very close to the pseudocode description of the scheme as given in the most recent version of the NIST submission. We present high-assurance open-source implementations of Kyber written in the Jasmin language, along with machine-checked proofs that they are functionally correct with respect to the EasyCrypt specification. We describe a number of improvements to the EasyCrypt and Jasmin frameworks that were needed for this implementation and verification effort, and we present detailed benchmarks of our implementations, showing that our code achieves performance close to existing hand-optimized implementations in C and assembly.
Efficient Regression-Based Linear Discriminant Analysis for Side-Channel Security Evaluations
Authors: Cassiers Gaëtan , Devillez Henri , Standaert François-Xavier , Udvarhelyi Balazs
Published: June 2023

32-bit software implementations become increasingly popular for embedded security applications. As a result, profiling 32-bit target intermediate values becomes increasingly needed to evaluate their side-channel security. This implies the need of statistical tools that can deal with long traces and large number of classes. While there are good options to solve these issues separately (e.g., linear regression and linear discriminant analysis), the current state of the art lacks efficient tools to solve them jointly. To the best of our knowledge, the best-known option is to fragment the profiling in smaller parts, which is suboptimal from the information theoretic viewpoint. In this paper, we therefore revisit regression-based linear discriminant analysis, which combines linear regression and linear discriminant analysis, and improve its efficiency so that it can be used for profiling long traces corresponding to 32-bit implementations. Besides introducing the optimizations needed for this purpose, we show how to use regression-based linear discriminant analysis in order to obtain efficient bounds for the perceived information, an information theoretic metric characterizing the security of an implementation against profiled attacks. We also combine this tool with optimizations of soft analytical side-channel attack that apply to bitslice implementations. We use these results to attack a 32-bit implementation of SAP instantiated with Ascon’s permutation, and show that breaking the initialization of its re-keying in one trace is feasible for determined adversaries.
Deep Learning Side-Channel Collision Attack
Authors: Staib Marvin , Moradi Amir
Published: June 2023

With the breakthrough of Deep Neural Networks, many fields benefited from its enormously increasing performance. Although there is an increasing trend to utilize Deep Learning (DL) for Side-Channel Analysis (SCA) attacks, previous works made specific assumptions for the attack to work. Especially the concept of template attacks is widely adapted while not much attention was paid to other attack strategies. In this work, we present a new methodology, that is able to exploit side-channel collisions in a black-box setting. In particular, our attack is performed in a non-profiled setting and requires neither a hypothetical power model (or let’s say a many-to-one function) nor details about the underlying implementation. While the existing non-profiled DL attacks utilize training metrics to distinguish the correct key, our attack is more efficient by training a model that can be applied to recover multiple key portions, e.g., bytes. In order to perform our attack on raw traces instead of pre-selected samples, we further introduce a DL-based technique that can localize input-dependent leakages in masked implementations, e.g., the leakages associated to one byte of the cipher state in case of AES. We validated our approach by targeting several publicly available power consumption datasets measured from implementations protected by different masking schemes. As a concrete example, we demonstrate how to successfully recover the key bytes of the ASCAD dataset with only a single trained model in a non-profiled setting.
Faster Montgomery multiplication and Multi-Scalar-Multiplication for SNARKs
Authors: Botrel Gautam , El Housni Youssef
Published: June 2023

The bottleneck in the proving algorithm of most of elliptic-curve-based SNARK proof systems is the Multi-Scalar-Multiplication (MSM) algorithm. In this paper we give an overview of a variant of the Pippenger MSM algorithm together with a set of optimizations tailored for curves that admit a twisted Edwards form. We prove that this is the case for SNARK-friendly chains and cycles of elliptic curves, which are useful for recursive constructions. Our contribution is twofold: first, we optimize the arithmetic of finite fields by improving on the well-known Coarsely Integrated Operand Scanning (CIOS) modular multiplication. This is a contribution of independent interest that applies to many different contexts. Second, we propose a new coordinate system for twisted Edwards curves tailored for the Pippenger MSM algorithm.Accelerating the MSM over these curves is critical for deployment of recursive proof< systems applications such as proof-carrying-data, blockchain rollups and blockchain light clients. We implement our work in Go and benchmark it on two different CPU architectures (x86 and arm64). We show that our implementation achieves a 40-47% speedup over the state-of-the-art implementation (which was implemented in Rust). This MSM implementation won the first place in the ZPrize competition in the open division “Accelerating MSM on Mobile” and will be deployed in two real-world applications: Linea zkEVM by ConsenSys and probably Celo network.

Published: June 2023

One of the challenges currently faced by Islamic education is the declining level of public trust in educational institutions with Islamic nuances. This happens because of the decline in morals in the midst of the development of the current era. Many think that Islamic educational institutions have failed as agents who play an important role in building a civilization. However, it is inevitable that many stakeholders say that the most important factor is that the strategy used by Islamic education is not right. Learning strategies play an important role in determining the success of education and the personal formation of students as a whole and comprehensively. Without the right strategy, the learning process will not run effectively and efficiently. Therefore, the teacher as the spearhead of education has an important role in the learning process. Strategic innovation in learning will prepare students as a quality generation of the nation to enter the era of globalization which is full of various challenges and very complex problems.

Archive management is an aspect that must be managed by schools, which still receive a lack of attention despite its importance. This lack of attention to management can be seen in elementary schools, which only rely on one school operator to manage the archives because of a lack of employees. As a result, a lot of data is not archived, damaged, lost, and unorganized. This study aims to produce a web-based one-gate digital archive by utilizing the learning.id account feature that is owned by educators and educational staff in Indonesia. The creation of a one-gate digital archive is carried out to improve the schoolâ€™s archive management and to increase school digitalization, so that educational services increase. This research uses plompâ€™s model development research. The advantage of using a one-gate digital archive is that it allows schools to easily change the web's appearance and features needed with low-cost. The result showed that the developed one-gate digital archive was valid and reliable, with an average score of 4,7, which was included in the excellent category. The existence of one gate digital archive is expected to help the principal and teachers in managing the archive. This research still needs to examine the effectiveness of this one-gate digital archive, so further research needs to be done.

Published: June 2023

The pandemic has prompted the proliferation of webinars for professional development in the teaching profession. This case study investigates the teachers' attitudes toward the webinars as professional development. The participants were the teachers from a junior high school in one public school in Indonesia. The researchers selected three participants based on the questionnaire by considering the frequencies following the webinars. The researchers conducted semi-structured interviews by adapting the three components of an attitude referring to behaviour, cognition, and affective. The study is significant to investigate how teachers perceive webinars as a tool for their professional development, describe the impacts, and as input for the educational organisation in conducting teachers' training. The results revealed the teachersâ€™ positive attitudes regarding behaviours, beliefs, and feelings towards the webinar as professional development. A webinar has eliminated the time and geographical boundaries in conducting professional development. Moreover, more professional networking and opportunities are additional advantages that bring more engagement and exposure to continuing their professional development. This research advocates that more webinars be held to develop the teachers' professionalism by related institutions and to open more access to growing teachers' careers by considering appropriate material and time based on the teachers' needs.

One of the competencies in 21st-century learning is critical thinking (CT). Many lessons carried out by teachers do not touch this ability because of the lack of learning innovation and the use of IT-based learning resources. This study aimed to determine and analyze the effect of using the OER (Open Educational Resources)-assisted Blended learning model on vocational students' critical thinking skills. The type of research used mixed methods with embedded design. The samples were 54 students of the Multimedia program at VHS (Vocational High School) in Surakarta, Indonesia, and the instrument used a test based on critical thinking skills, according to Facione. Quantitative data analysis used an independent t-test and the qualitative data used criteria for achieving students' critical thinking skills. The results of the study support the expectation that the BL model assisted by OER has a significant effect on student learning outcomes and that students have excellent critical thinking skills on the indicators of interpretation, analysis, evaluation, explanation, and inference.Â  On the other hand, students are weak in self-regulation.

Published: June 2023

The learning strategy by associating cultural elements with mathematics is called ethnomathematics. The application of ethnomathematics in learning is very important in fostering a love for local culture which is currently almost abandoned due to modernization. This study aims to explain the mathematical elements contained in the Indonesian traditional game, namely engklek (hopscotch). The research method used ethnographic research. Data collection techniques used were observation, interviews, field notes, and documentation. The data analysis used was a triangulation analysis which consisted of data reduction, presentation, and drawing conclusions. The results of the study show that there are several mathematical topics in the game, including plane geometry, the concept of the relationship between angles (opposite angles and straight angles), cube net, congruence, the concept of reflection, the concept of mathematical logic, and the concept of probability. Hopscotch can be used as a medium for learning mathematics as a learning innovation in schools. The application of ethnomathematics strategies can improve elements of character education in the form of honesty, togetherness, and high sportsmanship in carrying out traditional games.

Published: June 2023

In Bangladesh, present transportation system needs suitable control schemes to ensure safety and mobility to the road users. License Plate Recognition (LPR) is one of the control schemes which can be used to ensure road safety using video sensors. Moreover, from installation point of view, it is cheaper than Radiofrequency Identification (RFID) system. Automated LPR is adopted to reduce human involvement which causes loss in accuracy and reliability in reading license plate. The extracted information from LPR can be used in various schemes, such as electronic payment system, traffic surveillance and extracting vehicle trajectory. In this paper, we are presenting an offline dynamic LPR system, which uses geometric properties of Bengali alphabets stored in alphabet template database to recognize license plates from video. The system comprises of three main components: 1) License Plate Locating (LPL), 2) Character Segmentation (CS), and 3) Geometric Character Recognition (GCR). In this regard, the image is converted into a binary image considering morphological operations and color modification. A new ratio-based detection algorithm has been proposed for the segmentation of license plate. Finally, the alphabet template database and the character extracted from detected license plate are correlated to recognize alphanumeric character which deduces the plate number. Thus, the plate number can be utilized for further action.

In this study, anon-linear 3D numerical analysis using ANSYS was performed to investigate the influence of slab and column dimension on the punching shear capacity of the corner slab-column connection. Most research studied the punching shear stress, but none of them studied the distribution of punching shear stress, which was assumed to be linear in different codes. Verification models have been used to simulate existing experimental data. Two factors were taken into consideration for their influence on the punching shear strength of the concrete: the slab aspect ratio, column aspect ratio, and other factors are constant. Therefore, twenty-one models of different slab and column dimensions were investigated, and a comparison between the results obtained by the finite element analysis and the numerical results was made. Also, a comparison between shear stresses computed using two different methods in the Egyptian code, the simplified method, and the detailed method, and compare them with the Ansys models.

This study investigated the Cause-Effect of Five Child-Killer Diseases on Under-Five Mortality (Deaths) in Adamawa State, Nigeria. The study used Ex post facto and quantitative design. A secondary data was obtained from Adamawa State Primary Health Care Development Agency (PHCDA), Yola across the study area for the period of 2001 to 2020.The study used Multiple Regression Analysis to determine the Cause-effect of the Five Childkiller Diseases on Under-Five Mortality in the study area. The study revealed that; Polio needs to be excluded from the Five Child-Killer Disease since there is no death associated with polio disease for the period under review in the study area. The results also revealed that the deaths due to diarrhoea have a significant causal relationship on Under-Five Mortality, while deaths due pneumonia, measles and tetanus has insignificant causal relationship on Under-Five Mortality in the study area. Based on the overall model, the Five Child-Killer Diseases have a Causeeffect of 64% on Under-Five Mortality in the study area. In view of the above, the study recommends that Adamawa State Primary Health Care Development Agency, Yola whose primary responsibility among orders is to curb and reduce the spread of Child-Killer Diseases among vulnerable children of ages; needs to review and strategies their action plans, since the Cause-effect is still high.

Malware is one of the biggest problems modern internet users face. Private data and pricey computing resources are seriously threatened by the rise in malware attacks. Anti-malware businesses rely on signatures, which do in fact involve regular expressions and strings, to find malware and its related families. Recent malware attacks in recent years have demonstrated that signature-based techniques are error-prone and easily avoided by sophisticated malware programs. This essay provides an introductory overview of malware and analysis techniques used, as well as detection techniques used by researchers.
Review "Smoker/Non-Smoker Classification of People Using a Speech Signal"
Authors: Khudhur Zaal Ibrahim , Faisal Mohammad Yusra
Published: June 2023

Speech is a behavioral biometric that can reveal a person's age, gender, race, and emotional state. The speech signal may also be used to ascertain a person's behavior, such as whether or not they smoke or take drugs. One of the topics that is frequently studied in the field of speech technology is the smoking habits of speakers. Over the past years, a lot of research has been done in this area, but little progress has been made in this field. As deep learning techniques have advanced in most machine learning fields, they have replaced earlier research techniques for speech recognition and verification. The most cutting-edge method for confirming and recognizing a speaker's identity is currently deep learning. This study's objective is to analyze research that uses speech signals and artificial intelligence to distinguish smokers from non-smokers. Every speech recognition system uses a variety of algorithms to convert sound waves into information that can be interpreted and processed by the system, which then generates an output that can be used as needed.

The spatial formation of multi-use urban areas is one of the main reasons for the emergence of some positive or negative social phenomena among the population in Egypt, where the value of the urban space lies in the total social and cultural relations that arise in it and its ability to create opportunities for interaction between a different group of individuals. Hence, this research discusses the concept and evaluation of urban spaces in terms of the positives or negatives of multi-use areas and their role in achieving social sustainability in closed urban communities in Greater Cairo. Therefore, the study aims to evaluate mixed-use urban spaces, from a functional and social perspective, which is a tool to increase the social sustainability of urban communities in general and closed mixed urban communities in Egypt in particular. So that some conclusions and recommendations can be made on how to establish for mixed-use lands as a basic approach in sustainable urban development.

Published: June 2023

The first revolution in the 18th century saw the harnessing of water and steam power, exploitation of electricity took place in the second revolution and the exploitation of computer science technology in the third revolution. The fourth and fascinating revolution has started with the advent of new technologies like Artificial Intelligence (AI), Machine Learning and Robot Process Automation (RPA). The above disruptive technologies significantly disrupt the role of a company secretary. A day is not far when Artificial Intelligence is also sitting in the boardroom along with other human Directors. New technology will increasingly change the way the companies work and also the work as a company secretary and governance professional. Technological innovation leads to new corporate governance challenges in terms of ethics, fairness and transparency. The changes need to be embraced with boards and stakeholders suitably advised.
Development of Affordable Portable Oscilloscope Using Vacuum Tubes
Authors: Aaron Jelačić Maximilian
Published: June 2023

The goal of this project is developing an affordable oscilloscope for the average hobbyist and making it simple to use and build. The developed oscilloscope is an analog oscilloscope. Because they are much simpler to build than digital ones, they are generally more resistant to high voltages and allow the user to measure voltages up to hundreds of volts without damaging the oscilloscope. This gives the user a greater freedom in experimentation. As the oscilloscope is an analog one the display will be provided with a cathode ray tube. Having a CRT display makes the driving circuit of the display much simpler than a digital one. To allow the oscilloscope to handle high voltages and to be able to power the x and y deflection on the CRT, vacuum tubes will be used. Even though vacuum tubes consume and waste power for the heating of their cathodes, that will only present a couple watts of loses that can be ignored in this prototype development.
Aksesibilitas Lembaga Think Tank Dalam Upaya Pengarusutamaan Gender Di Daerah Istimewa Yogyakarta

Published: June 2023

Ketimpangan gender menjadi salah satu isu strategis di wilayah Daerah Istimewa Yogyakarta (DIY) dengan berbagai keberagaman karakteristik dan sosial. Berbagai macam bentuk isu yang muncul meliputi kekerasan, yang mana seringkali terjadi pada perempuan. Hal tersebut dapat dilihat dari tingginya tingkat Kekerasan Dalam Rumah Tangga (KDRT) yang terjadi di kelompok masyarakat DIY. Berbagai macam upaya telah dilakukan oleh pemerintah, dimana salah satunya adalah Gender Corner. Meskipun demikian, upaya pemerintah tidak berbuah hasil yang optimal. Dengan ini, hipotesis dari penelitian yakni bahwasanya organisasi think thank mampu mengoptimalkan rencana strategis pemerintah dengan strategi PUG (Pengarusutamaan Gender). Penelitian bersifat deskriptif kualitatif dengan menggunakan metode pengambilan data berupa wawancara mendalam dan dokumentasi. Obyek penelitian merupakan lembaga think tank di DIY yaitu CV. Multi Lisensi dan PT. Sinergi. Kedua lembaga tersebut telah menjadi pakar terhadap implementasi strategi PUG. Penelitian berfokus pada empat poin aksesibilitas lembaga think thank dalam upaya PUG yang meliputi akses, partisipasi, kontrol, dan manfaat. Sebagai hasilnya, didapatkan bahwa aksesisibilitas lembaga terhadap keempat poin penting tersebut dapat dikatakan cukup baik terkecuali pada poin manfaat. Akses, partisipasi, dan kontrol dalam pelaksanaan PUG di daerah DIY oleh lembaga think tank dikatakan baik dengan adanya transaparansi data hingga penyediaan fasilitas oleh pemerintah. Meskipun demikian, manfaatnya masih belum terwujud, dimana kesetaraan gender masih belum tercapai di wilayah DIY. Dengan demikian, penelitian merekomendasikan kepada berbagai pemangku kepentingan termasuk lembaga think tank sekaligus pemerintah untuk menggencarkan kembali agenda PUG. Berbagai kegiatan tambahan pun diperlukan mencakup sosialisasi, pendampingan, hingga pengarahan.

An increasing number of parents refrain from vaccinating their children. This causes lower immunisation coverage, resulting in disease outbreaks. Online misinformation about early-childhood vaccination is a potential cause of this problem. This study tests whether a warning tool, with the appearance of a traffic light, can influence parents’ information choices. An online experiment was conducted with parents and expecting parents (N = 179) with varying pre-existing attitudes and in different decision stages. Participants were asked to select three vaccine-related web links on a Google search result page either with or without the warning tool present. Results showed that participants in the warning tool condition (i.e., who saw reliability labels) selected a higher number of links marked as reliable compared to participants in the control group. No significant moderating effect of decision stage and pre-existing attitude were found. As our findings suggest that a warning tool can lead to better-informed vaccination decisions, the implementation of such a warning tool may prove worthwhile.
