Predictors of university students’ intentions to enroll in computer programming courses: a mixed-method investigation

Students in technology majors such as Computer Science and Information Technology need to take a series of computer programming courses to graduate. Yet, not all students will persist in taking programming courses as required, and little is known about the factors influencing their enrollment intentions. Research is needed to better understand which factors predict students’ enrollment intentions for programming courses. Based on Expectancy-Value Theory, we surveyed three hundred university students in China to measure their intentions of enrolling in future programming courses and factors influencing their enrollment intentions. Mediated Multiple Indicators Multiple Causes models were run to identify the relationships between these factors and enrollment intentions. Expectancies, intrinsic value, attainment value, and utility value of the courses directly predict enrollment intentions. Peer comparison, quality of teaching, and programming experiences were found to influence enrollment intentions through expectancies and values indirectly. No gender difference was found in expectancies and enrollment intentions. Qualitative data analysis confirmed the findings from the quantitative data analysis and further revealed that course difficulty is another major factor influencing enrollment intentions. These findings have implications for supporting students' expectancies and values in computer programming and curriculum design.

Computer Program for Primer Design for Loop-Mediated Isothermal Amplification (LAMP)

Introduction. To date, numerous methods of nucleic acid amplification have been proposed, and each method has a number of advantages and disadvantages. One of the most popular methods is Loop-mediated isothermal AMPlification (LAMP). Unlike thermocyclic reactions, such as PCR (polymerase chain reaction), which require three temperature changes and expensive equipment, in LAMP, the entire reaction takes place at one and the same temperature and at the maximum rate possible. An important component of LAMP-amplification is primers (usually 20–25 nucleotides), which need to be matched to a specific part of the nucleotide sequence. It is known that DNA sequence contains four nucleotides: A — adenine and T — thymine, G — guanine and C — cytosine. There is a huge variety of permutations of these nucleotides, and it is practically impossible to analyze such a large amount of data manually. Therefore, there is a need to use modern computer technologies. More than 150 computer programs have been proposed for the design of PCR primers, while for LAMP-primers there are less than 10 of them, and each of them has a number of drawbacks, e.g., in terms of the length of the analyzed site. Therefore, this work is aimed at developing a new domestic computer program for the design of specific primers for LAMP.Materials and Methods. The primer search algorithm was based on a linear search for a substring in a string, taking into account the criteria of primer selection for LAMP. The program complex of LAMP-primer design was implemented in Python programming language. The bioPython library was used to work with various DNA and RNA, and the Qt framework was used to develop the interface.Results. A modification of the direct sampling method using a stencil approach was proposed, taking into account the GC composition and annealing temperature of primers depending on their structure. A software package with a friendly interface was developed. It took into account the design criteria of primers: certificates of registration of computer programs (LAMPrimers iQ No. 2022617417 dated April 20, 2022, LAMPrimers iQ_loop No. 2023662840 dated June 14, 2023) were received. The program is in the public domain at https://github.com/Restily/LAMPrimers-iQDiscussion and Conclusion. The developed software packages can be used for research and analysis in molecular biology and genetics, to create diagnostic test systems that provide high sensitivity and reliability of detection of specific DNA and RNA. The software packages can be used in research institutes and laboratories engaged in the amplification of nucleic acids. The results of evaluating the selected sets of primers for the LAMP reaction were tested, and the effectiveness of working sets using the LAMPrimers iQ program was experimentally proven by the example of the detection of genetic material of the SARS-CoV-2 coronavirus.

Bridging the engineering skill gap in Nigeria: Preliminary findings and recommendations of the E4I survey

The paper presents the key findings and recommendations of an evidence-based survey report on the engineering skill gap among young engineering graduates in Nigeria. The outcome of the study highlighted the lack of technical, problem-solving, research and development, and management skills in the country’s young engineering graduates. Integrating emerging technologies like artificial intelligence, additive manufacturing, virtual reality, computer programming, computer-aided manufacturing, and computer-aided design into the curriculum was strongly recommended for the training of young engineering students in Nigerian higher education institutions. Other recommendations for skill augmentation include; enabling young graduates to develop their optimisation, modelling, simulation, design, creativity, technical, practical, machining, operation, and management skills to boost their hands-on engineering proficiencies. Strong emphasis was also on the importance of a one-year post-graduation internship program to upskill all young engineering graduates and provide a head-start in industrial settings. Lastly, adopting an outcome-based education (OBE) engineering training curriculum was recognised as crucial for addressing the skills gap.

Initial training in design of computer programs using UML

Introduction. Design is commonly acknowledged as a key process in the life cycle of computer programs and softwareintensive systems. The process efficaciously reveals creative capabilities of the author programmer and predetermines the basic advantages as well as shortcomings of the resulting program product, service or system. Design automation and other kinds of its support have been emerged simultaneously with onset of the software industry. From the beginning of the century the MDA (Model Driven Architecture) approach grew famous, offering to comprehend a design of a program as a process of sequential transformation of the program’s models, represented in UML or in other languages related to UML. Without becoming dominant, the MDA approach successfully evolves inside of a broader approach called MDE (Model Driven Engineering). Mastering UML and understanding of its role in MDE appears to be a prerequisite for a seamless entering of a professional programmer into domain of engineering of program systems. This provision justifies an increased attention to methods of UML teaching and to peculiarities of UML learning, and, moreover, to the professional education in the area of programs and program systems design technologies. This paper is aimed to draw attentions to challenges of the initial training in UML and tackle the challenges contributing a methodology and tools for sake of fostering the quality of education in program design. Materials and methods. The research is based on the university syllabi, the author’s lecture notes on software engineering, reports on laboratory works and course papers, protocols of experimental and sample runs of the developed programs, scientific publications, including pedagogical and engineering periodicals, conference materials, Internet resources, such as sites of the ACM, the OMG and others. The following research methods were used: system analysis of the own experience in program design as well as experience remarkable in student’s works; theoretical conceptual modelling of the program design including modelling of design scenarios; a trial implementation of the developed algorithms. Research results. A conceptual cognitive model of design as of a process during program development is proposed, highlighting the designer’s behavior when dealing with project artefacts. Feasible scenarios of analytic and advisory intervention into the design process are specified, using the model. A sample architecture of a program tool suitable for such an intervention is proposed as well as algorithms that enable online critical evaluation of the project’s current state, prompting feasible tracks of the project’s evolvement, revealing designer’s ideas and pointing some UML misuse. The algorithms are built in a program tool named Procrust that implements the proposed architecture. Trials of Procrust show that it basically fits to primary training of software design using UML and, in particular, to a training in the MDA/MDE methodology. Conclusion. The research results enable to set up an environment for comfortable and efficient program design using UML due to employing the proposed analytic and advisory support of the design process. Algorithms of the support and supporting program tools are targeted at initial design training on curricula of higher school and secondary vocational education. The algorithms foster in-depth study of UML and acquiring of advanced software design skills.

Positional trueness of three removable die designs with different root geometries manufactured using stereolithographic 3D printing

Statement of problemThree-dimensional (3D) printed casts are a suitable alternative to dental stone casts. Contemporary dental design computer programs permit designing definitive casts with removable dies with different root geometries and retention mechanisms. Studies on the positional trueness of 3D-printed removable dies with different root geometries are lacking. PurposeThe purpose of this in vitro study was to investigate the 3D displacements of three 3D-printed removable die designs with different root geometries. Material and methodsThe digital file of a dental stone alveolar cast with root-form removable dies (MOD UJ IV Fixed Prosthetics; Ivoclar AG) was used as a reference to create 3 removable die and alveolar cast designs (Root Form, RF; Conical, CON; Cylindric, CYL) with different root geometries in 2 dental design computer programs (DentalCAD 3.1 Rijeka; exocad; GmbH; InLab CAD 22.0; Dentsply Sirona). 3 equidistant Ø1-mm spheres (C, Cervical; M, Middle; O, Occlusal) were designed on the buccal surface of the coronal portion of the removable die to evaluate their displacement. A total of 45 alveolar casts with 45 removable dies were fabricated using a stereolithographic 3D printer (Form 3; Formlabs); each die group consisted of 15 specimens. After fabrication and postprocessing, the specimens were scanned, and their digital files were analyzed in a metrology-grade computer program to evaluate the displacement of the removable dies with respect to the position of the die in the master reference file. Subsequently, the data were analyzed using a 3-way analysis of variance (ANOVA) followed by step-down Bonferroni-corrected pairwise comparisons (α=.05). ResultsTwo statistically significant 2-way interactions were detected between the independent variables, die design and direction (P<.001), and location and direction (P<.001). The post hoc analysis identified significant differences between the displacement values of RF and CYL (P<.001) and RF and the CON (P<.001) designs on the Y axis. The measured displacements were statistically different between the C and O locations on the Y axis (P=.001) and the M and O locations on the Z axis (P=.006). ConclusionsThe root geometry of a 3D-printed removable die and alveolar cast can affect seating, and variable degrees of tipping of the removable die can be seen. The seating and congruence of the removable die with the interocclusal space and relationships observed intraorally should be confirmed before adjusting indirect restorations.

A Data-Driven Smart Evaluation Framework for Teaching Effect Based on Fuzzy Comprehensive Analysis

In recent years, the epidemic of communicable diseases has boosted the prevalence of online teaching activities. But how to make smart evaluation towards teaching effect has always been a technical barrier. As consequence, this paper utilizes fuzzy comprehensive analysis to deal with this problem from the perspective of big data mining. In particular, it proposes a data-driven smart evaluation framework for teaching effect based on fuzzy comprehensive analysis. Firstly, business data is timely collected from online courses as the basis, including teacher performance, teaching contents, student feedback, etc. Specifically, the initial data is encoded into structured format, from which characteristics of students behaviors can be analyzed. Then, the fuzzy comprehensive analysis is utilized to calculate evaluation results of teaching effect. Some simulation experiments are conducted based on the computer programming design, in which the proposal technical framework is implemented on a developed Web platform. The experiments reflect that the proposal can well realize evaluation of teaching effect.

ИНФОРМАЦИОННЫЕ ТЕХНОЛОГИИ В ПОДГОТОВКЕ СТУДЕНТОВ ТЕХНИЧЕСКИХ ВУЗОВ К ИНЖИНИРИНГОВОЙ ДЕЯТЕЛЬНОСТИ ПО СОЗДАНИЮ НАУКОЕМКИХ ТЕХНИЧЕСКИХ ОБЪЕКТОВ

The article presents the scientific results of the research carried out by the authors on the problem of teaching students of technical universities to create/develop intellectual property objects. Objects of intellectual property, unlike other types of property, have an intangible basis, are created on the basis of the latest knowledge of world science and technology. The main resource for creating objects/products of intellectual property are engineering and reengineering developments of scientists, engineering specialists and inventors to create science-intensive and high-tech technical, including transport objects of new generations, competitive on the world market and recognized as official state patents by departments in the aggregate of their distinctive properties from analogues and prototypes by objects of intellectual property. According to the Patent Law of the Russian Federation, objects of intellectual property are: objects of copyright, typology of integrated circuits, objects of industrial property and know-how. In turn, the industrial property cluster includes: technology patents, inventions, devices, utility model patents, industrial design patents, trademark certificates, computer programs and computer databases. It is extremely important that intellectual property as a commodity has its own value in the market of intellectual services and is an object of intangible assets of an enterprise/company. Authors-developers and enterprises/firms/corporations and the state as a whole are interested in creating intellectual property objects, since it makes a large contribution to the gross domestic product. Since it is impossible to teach how to create objects of intellectual property in a short time, the process of forming such a specialist must begin at the stage of professional training at a university.

BIOMAGNETISM OF DRUG-SENSITIVE AND DRUG-RESISTANT MALIGNANT TUMORS AFTER INJECTION OF FERROMAGNETIC NANOCOMPOSITE.

To measure magnetic signals from transplantable rat tumors and their counterparts resistant to cytostatics for evaluating thefeatures of theaccumulation of iron-containing nanocomposite Ferroplat. Doxorubicin (Dox)-sensitive and Dox-resistant Walker-256carcinosarcoma and cisplatin-sensitive and cisplatin-resistant Guerin's carcinoma transplanted in female Wistar rats were studied. Themagnetism of tumors, liver and heart was determined using Superconductive Quantum Interference Device (SQUID)- magnetometry in a non-contact (13mm over thetumor) way using specially designed computer programs. In a group of theexperimental animals, a ferromagnetic nanocomposite (Ferroplat) was administered as a single intravenous injection and biomagnetism was assessed in 1h. Themagnetic signals coming from Dox-resistant Walker-256carcinosarcoma in theexponential growth phase were significantly higher in comparison with sensitive tumor. Intravenous administration of Ferroplat increased biomagnetism by at least an order of magnitude, especially in resistant tumors. At thesame time, themagnetic signals of theliver and heart were within themagnetic noise. Theuse of SQUID-magnetometry with ferromagnetic nanoparticles as a contrast agent is a promising approach for visualization of malignant neoplasms with varying sensitivity to chemotherapy.

Common Mistakes and Their Fixes in Earthquake-Resistant Buildings

The primary way to design building structures refers to the stationary loads specified by the governing laws. However, the load pattern does not guarantee the appropriateness of the seismic design. To make matters worse, old or ancient structures are traditionally reinforced for gravitational loads. This study reveals that the traditional reinforcement, in most cases, harms the seismic performance of buildings. The authors introduced the approach of most computer programs for seismic design, along with their limitations. Then, the ancient Roman approach was explained, and the reasons for the survival of many of these ancient structures were exposed thoroughly. After that, classical advices were summarized briefly for good seismic design of structures and reinforcement. Finally, a few classical mistakes were identified in reinforcement design.

THE STUDY OF STRENGTH, DEFORMABILITY AND CRACK RESISTANCE OF CONCRETE SLABS REINFORCED WITH FACTORY-MADE WELDED AND KNITTED PRODUCTS

The advantages of using ready-made welded meshes and prefabricated frames in monolithic housing construction are a reduction in labor intensity, an increase in the pace and an increase in the culture of reinforcing work. In Russia, in the construction of buildings and structures, the use of reinforcement from factory-made products is not widespread due to a number of circumstances. These include the availability of cheap labor for manual knitting of reinforcement, the lack and high cost of adequate computer design programs for the rational layout of grids of unified standard sizes, etc. As part of the work performed, an assessment was made of the level of increasing safety, economic efficiency and reducing material consumption when using reinforcing products of various types of connections that meet the technical requirements. The purpose of the work was to obtain experimental data on the influence of the type of reinforcing products on the stress-strain state of reinforced concrete slabs and their consideration in the design. As a result of the work carried out, the excess of the bearing capacity of structures reinforced with the welded meshes over those with knitted meshes was recorded. The proposals have been formulated for using the results of the work in the development of regulatory, technical, organizational and methodological documents for amending the SP 430.1325800.2018 “Monolithic Structural Systems. Design Rules”.

Comparative evaluation of short or standard implants with different prosthetic designs in the posterior mandibular region: a three-dimensional finite element analysis study

The purpose of this study is to evaluate the stress distribution of splinted or nonsplinted restorations supported by 2 short or 2 standard dental implants in the mandibular molar region using three-dimensional finite element analysis. Two standard implants (4.8 × 10mm) were placed in the mandibular molar area. Two short implants (4.8 × 6 mm) were located in the mandibular molar atrophied area. Implant-supported prostheses were simulated with splinted or nonsplinted crowns design. Vertical load of 200 N and oblique load of 100 N were applied on the central fossa and the buccal cusps. Evaluation of stress distribution in implants and peri-implant cortical bone using the finite element analysis software (Ansys, Version 2020, R2), a multipurpose computer design program. The maximum principal stress of cortical bone around the implants was higher in nonsplinted crowns when compared to splinted crowns. The stress concentration of cortical bone surrounding implants increased as the implant length decreased either splinted crowns or nonsplinted crowns. The short implants with nonsplinted crowns showed lower stresses when compared to standard implants with nonsplinted crowns. The results suggest that the nonsplinted prostheses supported by short dental implants might be considered in the molar area of the atrophic mandible.

Implications for Distance Learning: Does Demographics Impact Students' Self-Perceived Proficiency in Information Technology?

The purpose of this study is to investigate the impact of demographics on students’ self-perceived proficiency in information technology and its implication for distance learning. Data for this study were collected from students in both undergraduate and graduate programs. Even though research suggests that demographics have an impact on users of information technology, this study, however, reveals no statistically significant relationship exists between demographics and students’ self-perceived proficiency in information technology. The study however shows that most rated themselves as proficient in using spreadsheets, PowerPoint, conducting online research, using chat/thread discussions, and word processing while most students described themselves as below proficient in computer programming and Webpage design. This study also highlights the implications of the findings to distance learning.
