Review matching task to diagnose basic review ability

Software development begins with writing a requirement definition document (RDD) specifying what software is to be built, and the RDD should define the necessary and sufficient conditions the software must satisfy. Preferably, the RDD is reviewed to guarantee its quality. However, the quality of reviews of such documents is not easy to evaluate, due to various review styles and the logical complexity of RDDs. Therefore, we regarded the review ability as the ability to match an RDD with a software and developed a game to make a matching task that can assess review quality. The task has four types of relationships, two-by-two classes of necessity (i.e., the RDD has no irrelevant sentences to define the given software) and sufficiency (i.e., the RDD covers all the parts of the software), between requirements and software, which are expressed in verbal and nonverbal forms. Results suggest that the game likely sufficiently simulated the process of making/reviewing RDD in the requirement definition process. Therefore, it is suggested that the matching task created through the game can be adequate to assess the review ability.

Possibility of regional revitalization by students’ IT

Recently, the number of students who can develop applications that can actually be used has increased. We thought that this power could be used for regional revitalization, we tried to connect the students and the region. As a result, we were able to create some interesting applications, some of which have become widely used in practice. For students, before going out to society, they can work on practical application development and know what kind of ingenuity is necessary to get them to actually use it. Although quality is not necessarily guaranteed in rural areas, the possibility of using the latest AI technology at a short development time and at a low cost was shown.

Heart Rate Variability Indices May Change Accompanying Cognitive Skills Improvement in eSports Tasks

Electronic sports (eSports) is becoming an increasingly popular subject of research with progress in the video game industry. However, the relationship between eSports and cognitive skills and heart rate variability (HRV) indices is not fully understood. Therefore, in this study, we analyzed changes in HRV indices in 20 healthy adult men while playing eSports and evaluated improvement in their cognitive skills before and after playing eSports using the Stroop test. The subjects were divided into two groups: 10 subjects who were trained in eSports for at least 1 hour a day, 5 days a week for 6 weeks, and 10 subjects who were not trained. The results indicated that subjects in the training group tended to have improved cognitive skills. In addition, in the group that temporarily improved their cognitive skills by playing eSports, similar changes were observed in HRV indices during eSports play, suggesting a parasympathetic nervous system dominance. Thus, it is suggested that the observed HRV changes were accompanied by the temporary improvement in cognitive skills induced by eSports tasks.

Nature versus Artifacts Body: One-Leaf Hyperboloid Type, Pair-Map Microcosm and Nested Economics

Toward digital-era, there is more increasing the portion of artifacts on the earth, and is attainable to the global environment of nature versus artifacts bodies. At the paper, we first suppose One-leaf Hyperboloid and the typical cases:Social (or enterprise) and Physical bodies as the base of nature vs. artifacts bodies. Second, the traditional pair-map is here developed, is semi-finalized at a generalization including Nash’s zone, and its 3D-like body is visually embodied as the two illustrations. Third, for a fractal(nested) mother of pair-map and its Nash’s zone, the shared equilibrium problem of 3D-type is discussed on the Trickle-down effort vs. Modern money theory (up) at Mt. Fuji type in the economic society. Finally, it is remarked that the latter might be better than the former at income distribution.
