Концепция иерархической структуры ментального опыта обучающегося программированию

The article raises the problem of insufficient attention to such a pedagogical category as the student's mental experience and its impact on cognitive processes. The possibility of considering the student's mental experience as an element of the content of education and as a resource for building an effective process of teaching programming at a university is discussed. Due to the fact that modern programming is built within the framework of technological processes, the activities of programmers are regulated. The program code is compiled in a formalized programming language, limited by syntactic rules and semantic constructions. Design patterns are used to facilitate the development of complex information systems. The pattern can be set both for the elementary level of abstraction - using structural operators of a programming language, and for the highest level - building an information system architecture. As part of the development of design patterns, representations of patterns are formed in the mental experience of the student. In the process of solving a programming problem, in the presence of an appropriate mental representation, a detailed analysis of the pattern execution algorithm does not occur in the cognitive processes of the student, the decision is formed directly on the basis of associative linking of information stimuli and elements of mental experience. The article lists the theses of the concept of the hierarchical structure of mental experience, which can be considered as a theoretical basis for the development of pedagogical technologies aimed at improving the efficiency of mastering professional competencies.

Modeling the Application of IHE QRPH Profiles in Data Integration Centers: A Practical Approach with 3LGM2.

The Data Integration Centers (DICs), all part of the German Medical Informatics Initiative (MII), prepare routine care data captured in university hospitals to enable its reuse in clinical research. Tackling this challenging task requires them to maintain multiple data stores, implement the necessary transformation processes, and provide the required terminology services, all while also addressing the use case specific needs researchers might have. An MII wide application of the standardized profiles defined in the IHE QRPH domain might therefore be able to drastically reduce the overhead at any one DIC. The MII DIC reference model built in 3LGM2, a method to describe complex information system architectures, serves as a starting point to evaluate whether such an application is possible. We first extend the IHE modeling capabilities of 3LGM2 to also support the five profiles from the QRPH domain that our experts evaluated as relevant in the MII DIC context. We then expand the DIC reference model by some IHE QRPH actors and transactions, showing that their application could be beneficial in the MII DIC context, provided they surpass their trial status.

Drug provision model of patients based on an architectural approach in the context of digital transformation of military healthcare

According to architectural modeling (the architectural structure of an open group), typed blocks of elements forming the basic components or layers of the architecture of a military medical organization are considered, combined into six domains with a schematic representation as typical architecture. The rational allocation of layers, their contents, interrelations, and directions of development provide an opportunity to effectively manage the complex multidisciplinary military medical organization during digital transformation. For the introduction and implementation of digital solutions, the analysis of the creation of an integrated module of a single digital contour for managing medical property resources indicates the feasibility of substantiating and developing reference functional models according to a single standard for describing business processes and the need to choose the most optimal methodology and notation for modeling reference functional architectures of a military medical organization. In a comparative analysis of the selected notations according to reasonable criteria, the business process model and designations were determined as the optimal and universal description language that most fully meets the needs of functional modeling of the architecture of information systems for the subsequent automation and digitalization of the management of medical property resources in a military medical organization. The reference functional model of the information system for the management of medical property resources is presented by the description of the processes of drug provision of admitted patients, which is one of the main target areas of the military medical organization considering its state task. Moreover, a well-founded and developed standard functional architecture in the notation of the business process model and notation 2.0 is presented as interacting pools displaying the subjects (participants) of the process with the tasks assigned to them. The methods and methodological approaches presented in the article, as well as models of functional architectures for providing medicines to patients admitted to a military medical organization, can be used as a reference in the digital transformation of the management of medical property resources at various levels of military healthcare.

Criterion for Ensuring the Effectiveness of the Management of the Global Maritime Industry

Introduction. The significant dynamic nature of modern geopolitical and military threats sets new requirements for evaluating the criteria effectiveness of solving maritime industry management problems, requires new methodological approaches and mathematical models for evaluating criteria, and determines a new architecture of information systems in the structure of which these approaches and models are implemented. This makes the issue of the analysis of the application of criteria and the development, research, and implementation of such models and systems extremely relevant.
 Aim and tasks. The purpose of the study is to create a methodological approach to evaluating the criteria that characterize the effectiveness of the management of the maritime industry, with the dynamic change of criteria due to the influence of threats and challenges.
 Results. A methodological approach has been developed to evaluate the criteria that characterize the effectiveness of the management of the maritime industry based on the model for assessing the convergence of the absolute values of the first derivatives of the criteria over time, which, at short time intervals, can be considered as criteria change trends. It has been established that instead of reducing transportation costs, management switches to the principle of ensuring optimal costs, which leads to an increase in the cost of freight and shock reactions in the sea transportation market. It was established that it is advisable to use the LSCI criterion as an indicator of the negative effect of “local optimization”. After determining the development trends of the criteria, their evaluation as well as the assessment of their convergence were carried out, which became the basis for proposing directions for improving the efficiency of maritime industry management.
 Conclusions. The developed methodological approach and the mathematical model of its implementation make it possible to conduct both quantitative and qualitative analyses of the effectiveness of management of the maritime industry. To increase the efficiency of management, it is proposed: to integrate port community systems; to increase the stability of the port infrastructure so that it can function in crisis conditions; to achieve coordination of management actions at all levels; to avoid “local optimization” and introduce integral optimization; to respond not only to direct threats but also to detect the cascading effects of threats.

Practical Use of ICT course in Libraries: Perspectives of MLISc graduates in Nepal

Although the Central Department of Library and Information Science (CDLIS) was founded in TU 27 years ago, the Masters in Library and Information Science (MLISc) program is less popular among recent graduates. The MLISc program's reputation and significance are dependent on how successfully it has adapted to emerging information and communication technology (ICT). It is an early attempt to assess the MLISc ICT course material, primarily focusing on how applicable it is to real-world professional situations.Working librarians from Nepal participated in a focus group discussion to assess how well the MLISc ICT course applied to their line of work. Participants have suggested that the basic and advanced ICT course topics in the MLISc curriculum should be distinguished clearly. Library automation, digital library software, and other advanced ICT courses are available. However, the library profession places a high value on graduates with a complete understanding of information system architecture, library automation, and digitization services.

Identifying Application Areas for Machine Learning in the Retail Sector

Machine learning (ML) has the potential to take on a variety of routine and non-routine tasks in brick-and-mortar retail and e-commerce. Many tasks previously executed manually are amenable to computerization using ML. Although procedure models for the introduction of ML across industries exist, the tasks for which ML can be implemented in retail need to be determined. To identify these application areas, we followed a dual approach. First, we conducted a structured literature review of 225 research papers to identify possible ML application areas in retail, as well as develop the structure of a well-established information systems architecture. Second, we triangulated these preliminary application areas with the analysis of eight expert interviews. In total, we identified 21 application areas for ML in online and offline retail; these application areas mainly address decision-oriented and economic-operative tasks. We organized the application areas in a framework for practitioners and researchers to determine appropriate ML use in retail. As our interviewees provided information at the process level, we also explored the application of ML in two exemplary retail processes. Our analysis further reveals that, while ML applications in offline retail focus on the retail articles, in e-commerce the customer is central to the application areas of ML.

Assessing the discordance rate of HER2 expression by immunohistochemistry between primary and secondary prostate cancer biopsies.

e17014 Background: Preliminary evidence suggests that human epidermal growth factor receptor 2 (HER2) expression may play a role in tumor cell proliferation in prostate cancer. Minner et al ( Clin Cancer Res, 2010) identified a prevalence of ~ 20% HER2 expression in prostate cancer. The aim of the study is to assess the prevalence and discordance rate of HER2 expression in prostate cancer patients with multiple prostate biopsies using immunohistochemistry (IHC) at a Veterans Affairs hospital. Methods: A single-center, retrospective chart review of at least 30 patients with prostate cancer that had two prostate biopsies based on data collected from the Computerized Patient Record System (CPRS) and Veterans Information Systems and Technology Architecture (VISTA). Demographic and laboratory data including age, race, Gleason score, and stage of cancer were collected under IRB-approved waivers for consent and HIPAA authorization. Formalin-fixed paraffin embedded (FFPE) prostate tumors were evaluated for IHC analysis by the Washington DC Pathology Department. HER2 expression was assessed using the VENTANA anti-HER2/neu (4B5) rabbit monoclonal primary antibody and scored as 0, 1+, 2+, and 3+. HER2 scores of 0 and 1+ to 3+ were categorized as HER2-negative and HER2-positive, respectively. The primary endpoints are the prevalence and discordance rate of HER2 expression in paired prostate samples. Results: In our predominately African American (94%) cohort of 32 patients with a mean age of 60 years, overall HER2 prevalence was 25% (n = 8) and 56% (n = 18) in the primary and secondary biopsies, respectively. The mean time between biopsies was 41 weeks and overall HER2 discordance was 56% (n = 18). Discordance from HER2-negative to HER2-positive was 38% (n = 12), while discordance from HER2-positive to HER2-negative was 6% (n = 2). The remaining discordance were from HER2-low to HER2-positive or vice-versa. The most common variance between primary and secondary biopsies was observed as +1 HER2 scoring category (n = 11). No significant associations were found between HER2 discordance and Gleason score or stage of cancer . Conclusions: In our cohort of patients with prostate cancer, HER2 expression was observed in 25% of initial biopsies and over 50% of secondary biopsies. Discordance of HER2 expression was found in over 50% of patients. A few patients had initial HER2-positive biopsies and subsequent HER2-negative biopsies. The majority of HER2 discordance involved patients who had initial HER2-negative biopsies and secondary HER2-positive biopsies with most showing +1 difference in IHC scores. This study could lead to the consideration of utilizing multiple prostate cancer biopsies to determine the eligibility for anti-HER2 therapy in future trials.
