Towards a layered architecture for error mitigation in quantum computation

In the past few years, the first commercially available quantum computers have emerged, in an early stage of development, the so-called Noisy Intermediate-Scale Quantum (NISQ) era. Although these devices are still very prone to errors of different natures, they also have shown to deal successfully with small computational problems. Nowadays, one of the challenges in quantum computation is exactly to be able to show that quantum computers are useful, whereby mitigating the effects of the faulty hardware is pivotal. Recently, a wide range of quantum error mitigation techniques have been proposed and successfully implemented, alternative to quantum error correction codes. Herein, we discuss several types of noise in a quantum computer and techniques available to mitigate them, as well as their limitations and conditions of applicability. We also suggest an hierarchy for them, towards the conception of a layered software framework of error mitigation techniques, and implement some of them in a quantum simulation of the Heisenberg model on an IBM quantum computer, improving the fidelity of the simulation by 2.8x.
Enhancement of 3-d pythocrypt using aes technique by generating the key using chitra kavya

&#x0D; &#x0D; &#x0D; The research work describes an attempt to enhance the 3-D Pythocrypt algorithm using the AES Symmetric encryption technique by generating the key using an ancient approach of Chitra kavya. 3-D Pythocrypt is a new technique where we use the properties of 3-D geometric shapes to encrypt and decrypt plain text. AES encryption is a standard approach for encrypting and decrypting the message using a single key for both approaches. The ideology of this research is to first encrypt the plain text using the 3-D Pythocrypt technique and the cipher text obtained is fed as an input to the AES encryption technique along with the key generated using the Chitra kavya to carry out the encryption in two phases.&#x0D; &#x0D; &#x0D;

METHODICAL ASPECTS OF THE ORGANIZATION OF DESIGN AND MODELING IN THE PROCESS OF FORMATION OF PROJECT-TECHNOLOGICAL COMPETENCE FUTURE TEACHERS OF LABOR TRAINING AND TECHNOLOGY

In the article, in order to motivate the activity of higher education students to design and technological activities, three groups of ways of motivating this type are substantiated. The first group includes design methods that affect active cognitive activity, promote self-realization of higher education. This includes creative design methods (theory of solving inventive problems, the clause of creative content). In order to motivate future teachers of labor training and technology to form project-technological competence, effective heuristic design methods based on methods of analogy, association, focal objects, bionic method, inversion method, «brainstorming», morphological-combinatorial matrices are identified. inversion and installation design method. The second group of ways to motivate the activity of higher education in the process of design and technological activities includes three methods of modeling: the method of geometric modeling, aimed at creating an idea of the appearance of the prototype; physical-like modeling, which reproduces the dynamics of processes, their values and parameters, types of dependencies and regular relationships that occur in the simulated prototypes; functional-like modeling used in the development of robotic devices that, not having the same physical nature as the prototype, mimic the behavior of living beings and «able» to respond to external stimuli. The third group of ways to motivate the project-technological activity of higher education seekers includes the means of project-technological activity for the study of professionally-oriented disciplines: applications for the Android operating system; computer-aided design (CAD) systems; application of 3D technologies. It is determined that for better mastering of educational material on design and modeling, it is possible to increase the involvement of higher education students in learning by making a group project. As a result, applicants for higher education will learn not only modeling, but also the creation of structures and preparation of the layout for printing. Key words: design, modeling, design-technological competence, teacher of labor education and technologies, design methods, modeling methods.
Artificial Intelligence: An Advanced Evolution In Forensic and Criminal Investigation

Abstract: It is aimed, with the use of modern sciences and technologies and also the use of new, latest and future technologies, such as artificial intelligence, to develop enhanced and extended ways to promote the technology for forensics of all its sectors (AI). A program or computer program is capable of carrying out human functions such as visual awareness, voice recognition, cognitive reasoning, strategic thinking, understanding from experiences, and solving complicated issues at a greater rate and with smaller mistake rates than humans. AI is also the most developing sector for advances in the field of forensics and the system of justice. In today's situation, specialists are faced with numerous problems because of enormous quantities of data, minute facts in the chaotic and complex environment, traditional lab architecture, and sometimes inadequate information, which might fail to do an inquiry or a miscarriage of justice. AI is a waffle to combat the difficulties of machine learning and profound learning. Case-based reasoning for error-free and objective outcomes in many forensic areas, neural networks, and reproductive results. The study discusses AI's current and potential future uses in forensic science. Artificial intelligence may be used in a variety of applications, including blood pattern recognition and analysis, crime scene reconstruction, digital forensics, image processing, and, of course, satellite monitoring.
Negotiation-Based Multi-agent System for Ambient Conditions Control in Accordance with Multiple User Preferences

The Internet of Things has set the foundation for countless innovative solutions, some of which are designed specifically for homes, offices, etc., with the aim to increase user comfort. In order to automatically increase user comfort by saving the user time and energy, the system has to obtain and process information about the conditions in the smart space, and the user’s needs and wishes. Context awareness, without which ambient intelligence could not be developed, relies on data collected from connected devices. Ambient intelligence is about meeting users’ needs and desires while taking context into account and making instantaneous adjustments to their actions and other context changes. In this paper, we propose a context-aware, user-centric multi-agent system that is able to independently determine ambient settings in a smart space according to the preferences of users present without any user intervention. The main advantage is that it serves more users, i.e., it is not focused on only one user and his preferences, but takes care of all present users and satisfies their wishes and needs regarding ambient conditions while harmonizing their different preferences. To achieve this, a negotiation process between intelligent user agents is proposed and described. The presented model is described on the use case of smart lighting.

The Study on the Characteristics of Community-Based Youth Education: Focusing on ‘2021 Jeju Youth Architecture School’

Objectives Community-centered youth education that develops the ability to solve problems in the local community is of great importance for the youth who must live in the era of the new normal after the pandemic. Therefore, this study intends to reveal how convergence thinking in architecture can play a role in the education of youth in the local community and what its limitations and possibilities are through a review of ‘2021 Jeju Youth Architecture School’.&#x0D; Methods First, a theoretical review was conducted on community-centered youth education and architecture education, which were the theoretical backgrounds for the development of the Jeju Youth Architecture School program. Next, the characteristics of the proposed program (educational subject, curriculum, educational content, etc.) were considered. Finally, the limitations and possibilities of the program were considered through analysis and evaluation of the results of the youth architecture school.&#x0D; Results As the educational goals of the program, ‘sociality’ to understand the social roles and responsibilities of architects, ‘creativity’ to understand how ideas are built into architectural spaces, and ‘locality’ to seek a role as a member of the community were shared. In order to realize the educational goals, the program could be divided into three stages: ‘value sharing, goal setting, suggestion and evaluation’. As a result of the evaluation, the architect's new role (sociality) and creative architectural alternatives (creativity) were highly evaluated for a clear social phenomenon called the corona pandemic. On the other hand, it could be revealed that the results of concerns about the region (locality) due to the rigidity caused by the corona were not relatively well evaluated.&#x0D; Conclusions ‘2021 Jeju Youth Architecture School’ was able to reveal that it has the characteristics of community-centered youth architecture education, such as developing a cooperative system and developing educational goals and programs among various local actors. In addition, it was confirmed that education using local resources can contribute to the discovery and resolution of social problems and the expression of creativity among young people.
Real-Time Experience with the Havruta Teaching Method and Application of Flipped Learning in a Online Psychiatric Nursing Class

Objectives In this study, phenomenological research was conducted to examine real-time online experience with the Havruta teaching method and application of flipped learning in a psychiatric nursing class.&#x0D; Methods In this study, eight students currently enrolled in their third year of a nursing program participated in individual in-depth interviews for data collection from March 3 to April 23, 2021. The collected data were analyzed using Colaizzi’s phenomenological method of analysis to explore the nature and meaning of experience.&#x0D; Results Ten meaningful themes were derived through the real-time online experience with the Havruta Teaching Method and application of flipped learning in a psychiatric nursing class. The four theme clusters follow: (1) a teaching method that aids in longer memory retention, (2) a teaching method that boosts interest and motivation, (3) the shortage of time, and (4) a desire for improvement in parts of the lecture. In particular, the study participants noticed longer memory retention of learning material and hoped to have more classes utilizing the same instructional method in the future.&#x0D; Conclusions This study demonstrated that self-driven, learner-centered teaching methods, such as the Havruta teaching method, can improve nursing students’ learning efficiency and stimulate their academic interest. Furthermore, as online learning in universities is predicted to be on the rise even after the end of the COVID-19 pandemic, efforts will be needed to modify existing teaching methods accordingly and establish appropriate ways to promote the anticipated learning outcomes.
Exploring the Experience of the Daycare Center Director's Role as a Mandatory Reporter for Child Abuse and Neglect

Objectives The purpose of this study was to explore perceptions, actual responses, and demands of child care center directors as a mandatory reporter for child abuse and neglect.&#x0D; Methods Six directors of child care center, which are legally obligated to report child abuse and neglect, were interviewed twice each. If it needs more information, one or two additional interviews were conducted by telephone or in person. A qualitative research method was used for analysis.&#x0D; Results Directors’ perceptions about a mandatory reporter for child abuse and neglect were as follows: recognized as a role that (1) should be performed by obligation, (2) is accompanied by fear, (3) is troubled by a relationship, and (4) is a difference of position in the job. The actual response to the mandatory reporting of child abuse and neglect was classified into (1) observing and confirming more sensitively than an immediate report, (2) giving a direct or indirect warning rather than a report, (3) mediating conflicts related to the report, and (3) taking responsibility after careful reporting. To develop ability as a mandatory reporter for child abuse and neglect, directors’ demands were as follows: (1) improvement of education for directors obligated to report child abuse and neglect, (2) protection of reporting persons and daycare center, and (3) improvement of perspective on reporting of Child abuse and Neglect.&#x0D; Conclusions The director of the daycare center recognized that there were things to consider as a director when taking on the role of a mandatory reporter to report child abuse and neglect. Therefore, rather than reporting immediately as specified in the actual law, they prioritized their own countermeasures. In addition, in order to fulfill the role of reporting duty as the director of child care center, various improvements were requested. The results of this study will provide basic data to understand the experience of the director of a daycare center as a person obligated to report child abuse, and will be helpful preparing an effective plan for the role of a report duty officer reflecting the characteristics.
Structural analysis on the effect of learner-centered classes on creative thinking and self-management competencies of high school students through learning motivation and school happiness

Objectives In this study, the structural relationship between the factors of learner-centered classes on creative thinking and self-management competencies through learning motivation and school happiness was compared and analyzed, focusing on the application of the 2015 revised curriculum and before and after COVID-19.&#x0D; Methods To this end, structural equation model analysis and difference analysis were conducted on high school student data in the 1st, 4th, and 5th years of the BELS(Busan Education Longitudinal Study), and mediating path analysis using phantom variables was conducted to verify the two parameter paths, respectively.&#x0D; Results First, as a result of analyzing the differences before and after the application of the 2015 revised curriculum, high school students (2019) showed a statistically significant increase in all variables compared to high school students (2016) before the application. In the pre- and post-COVID-19 analysis, it was confirmed that self-management competency increased and learner-centered classes decreased after COVID (2020 high school 2) compared to before COVID (2019 high school 1), and no significant difference was found in the remaining variables. Next, as a result of verifying the mediating path of the research model, learning motivation and school happiness in learner-centered classes and creative thinking competencies were found to have complete mediating effects in all years, and partial mediating effects in learner-centered classes and self-management competencies. In particular, after COVID-19, the influence of all mediated routes decreased significantly compared to before COVID-19.&#x0D; Conclusions Based on the results of the study, it was possible to confirm the influence of the 2015 revised curriculum and COVID-19, the importance of learning motivation and school happiness in the high school field.

Objectives The purpose of this study is to establish self-direction and learning behavioral strategies as major variables affecting the problem-solving ability of freshmen in college, and to verify the mediating effect of learning behavioral strategies in the relationship between self-direction and problem-solving ability.&#x0D; Methods This study conducted a survey on freshmen who entered a university in Seoul in 2021. The survey period was from June 21 to June 25, 2021, and 1,036 copies were finally included in the analysis, excluding insincere responses from the collected data. Frequency analysis, descriptive statistical analysis, independent sample t-test, one-way analysis of variance (ANOVA), correlation analysis and regression analysis were performed on the collected questionnaire data using SPSS 26.0 program.&#x0D; Results Self-direction and learning behavioral strategies (r=.499, p&lt;.001), self-directedness and problem-solving skills (r=.589, p&lt;.001), and learning behavioral strategies and problem-solving abilities (r=. .453, p&lt;.001) showed a statistically significant quantitative correlation. Also, the partial mediating effect of the learning behavior strategy (Z=14.98, p&lt;.001) on the relationship between self-direction and problem-solving ability was verified.&#x0D; Conclusions The analysis results of this study suggest that it is necessary to prepare a plan to create an educational atmosphere that enhances self-direction and reinforces learning behavioral strategies to improve problem-solving abilities of freshmen in college and applies them to the higher education field.
Combinatorial testing and model checking

This issue contains two papers. The first paper focuses on combinatorial testing, and the second one focuses on model checking. The first paper, ‘Combinatorial methods for dynamic grey-box SQL injection testing’ by Bernhard Garn, Jovan Zivanovic, Manuel Leithner and Dimitris E. Simos, concerns combinatorial testing for SQL injection. Code injections attacks, and in particular SQL injection (SQLi) attacks, are still among the most critical threats for web applications. These attacks rely on exploiting vulnerabilities, which must be actively chased to deploy a secure system. Leveraging combinatorial testing, the authors propose novel attack grammars to generate SQLi attacks against MySQL-compatible databases. One originality of this contribution resides in dynamically optimizing and improving the attack grammars to the context. This context-sensitive adaptation technique is supported by a prototype tool named SQLInjector+ and is validated and benchmarked on a representative set of web applications under test. The contribution is accompanied by a nice addition to the field: a simple framework called WAFTF for testing the filtering techniques of web application firewalls such as ModSecurity. (Recommended by Yves Le Traon) The second paper, ‘Comprehensive evaluation of file systems robustness with SPIN model checking’ by Jingcheng Yuan, Toshiaki Aoki and Xiaoyun Guo, presents a study that comprehensively evaluates the robustness of file systems using a model checking approach, covering the majority of the mainstream file system types and both single-thread and multi-thread modes. In particular, to abstract real file systems, the authors developed Promela models optimized to avoid state explosion during model checking and used an SPIN model checker to check these models for detecting corner-case errors during an unexpected power outage. The authors analysed counterexamples generated by model checking to determine an improved file system model that is capable of preventing errors in most mainstream file system types and then rechecked the improved file system model and verified the absence of all critical errors.
