Abstract

Association rule mining techniques can generate a large volume of sequential data when implemented on transactional databases. Extracting insights from a large set of association rules has been found to be a challenging process. When examining a ruleset, the fundamental question is how to summarise and represent meaningful mined knowledge efficiently. Many algorithms and strategies have been developed to address issue of knowledge extraction; however, the effectiveness of this process can be limited by the data structures. A better data structure can sufficiently affect the speed of the knowledge extraction process. This paper proposes a novel data structure, called the Trie of rules, for storing a ruleset that is generated by association rule mining. The resulting data structure is a prefix-tree graph structure made of pre-mined rules. This graph stores the rules as paths within the prefix-tree in a way that similar rules overlay each other. Each node in the tree represents a rule where a consequent is this node, and an antecedent is a path from this node to the root of the tree. The evaluation showed that the proposed representation technique is promising. It compresses a ruleset with almost no data loss and benefits in terms of time for basic operations such as searching for a specific rule and sorting, which is the base for many knowledge discovery methods. Moreover, our method demonstrated a significant improvement in traversing time, achieving an 8-fold increase compared to traditional data structures., Comment: 12 pages, 13 figures, preprint of journal article

Abstract

Introduction: Introduction: Human health has a profound effect on physical performance and productivity, the country's economy, the moral climate in society, the upbringing of the younger generation, and also reflects the way and quality of life. An important factor in our society for promoting human health is a healthy lifestyle. Indicators of the general human culture can be considered attention to their health, the ability to provide individual prevention of deterioration of health, as well as conscious adherence to a healthy lifestyle. Recently, the problem of deteriorating student health has been receiving more attention because many students have different chronic conditions. Therefore, one of the priorities in shaping students' health today is to provide the right conditions for the education and education of a physically and mentally healthy person. Material and Methods: In our study, 152 students enrolled in their second year of study enrolled in their first bachelor's degree. By randomization, they were divided into two groups: control (n = 76) and primary (n = 76). The groups were identical in age and physical development. The control group students attended regular physical education classes according to the schedule. The students of the major also attended physical education classes on a schedule, where they implemented the developed and proposed program. Results: The proposed comprehensive curriculum for physical education of students took into account the results of the student survey at the beginning of the study and was divided into three periods: introductory, basic and final. Each of the physical education programs offered differed in its basic components. As a result of the implementation of the proposed physical education program, students of the main group experienced significant improvements in the results of tests that determine the state of the respiratory and cardiovascular systems: Stange test (60.80 ± 0.72 s) (p <0.05), Gencha test (29.08 ± 0.39 s), the Skibinsky index (32.42 ± 0.92) and the Ruffier functional test (7.30 ± 0.28). Conclusions: According to the results of the research, we can state the positive impact of the proposed physical education program on the level of physical health of students. A significant improvement in the functional status and physical performance of students in the core group is evident. Application of the developed program has contributed to positive changes and promotion of health, adaptation to training and improved quality of life. [ABSTRACT FROM AUTHOR]
