    Ideophones (giongo/gitaigo) are sound-symbolic or iconic words found in many languages. They have been attracting increasing attention in the fields of linguistics, psychology, and more broadly, cognitive science. Japanese ideophones have been extensively studied due to their highly conventionalized sound symbolic system; however, research often relies on native speaker linguists’ introspection, particularly concerning the form-meaning correlation. This study provides an automatic analysis of Japanese ideophones using full dictionary entries with Python3 and its library Polas. Additionally, this study offers an initial analysis using the automatically generated comprehensive data, with a special focus on their form-meaning correspondences, particularly whether they refer to sound. The study not only reduces researchers’ workload, but also enables more objective, detailed, and comprehensive analysis of sound symbolism in Japanese ideophones and other languages, facilitating large-scale cross-linguistic comparisons.

    Tourism digital transformation, where efficient management using Information and Communication Technologies is required including data utilization for evidence-based decision making. Many kinds of data are collected, and people are struggling to utilize them for efficient decision making. One of the ways to show the data to users is data-visualization dashboards. Some dashboards are used to show data to ordinary people who are interested in data or data utilization but not good at analyzing them by themselves. Conventional data dashboards only show graphs and data. Ordinary people find it difficult to make full use of them. It has two main reasons; people have little sense to new kinds of data which are unfamiliar to them; they can’t imagine what actions they should take based on the data or dashboards. In this paper, we identify what is required to help such people utilize data, and propose a new action-first dashboard for data utilization and how to develop it

    In this paper, a method for detecting microsatellite instability (MSI) status from colorectal cancer biopsy samples by deep learning with a convolutional neural network (CNN) using a pathological Whole Slide Image (WSI) is proposed. The proposed model has a mechanism to add weights to feature maps obtained from images of multiple sizes and resolutions as inputs. The MSI detection for a specimen is performed by adding a process to expand the cancer cell area and a confidence measure in consideration for the characteristic of the biopsy samples. In addition, the model used was changed according to the size of the specimen. The method used in the previous study detected the MSI status on the patch with an accuracy of 76.0%, whereas the method used in this study achieved an accuracy of 88.3%.

    Since the proposal of the RSA cryptosystem as an implementation of public-key cryptography proposed by Diffie-Hemann in 1976, public key cryptosystems became the essential infrastructure to ensure three basic elements of information security such as confidentiality, integrity, and availability in today’s advanced information society. Not only RSA cryptosystem but also the system using elliptic or hyper-elliptic curves, their security depend on the difficulties of order counting problems in each field. However, the algorithm proposed on the quantum computer by Shor enables to solve these types of problem in polynomial time order operations and threaten the securities. Thus a cryptographic system that is expected to maintain security in consideration of currently known algorithms on quantum computers and future possibilities called Post-Quantum Computer Cryptography (PQCC) is required. In this paper, among PQCC which is said to be unbreakable even with a quantum computer in a practical time, we consider one using self-dual error-correcting code over a integer module ring. We also refer to a decoding algorithm using Information set on the cryptosystem.

    In education, it is considered important to take into account the personality and characteristics of each child, pupil, and student, and attempts have been made to implement educational practices that respond to this. However, when a single teacher is dealing with a large number of students, they are forced to adopt a uniform approach. In particular, at universities, education has traditionally been conducted in a one-way, teacher-centered manner, but the situation is changing with the advancement and spread of e-learning systems. Systems for understanding learners’ personalities and educational preferences and improving educational effectiveness are thought to be in the research stage, but basic theories have long been studied in the fields of psychology and pedagogy. This paper examines the relationship between the MBTI, a representative indicator of personality diagnosis in psychology, and the Felder-Silverman learning style model, which is widely used to understand learning styles.

    The use of the Internet for information gathering, including web browsing and social media, has become a common practice, and there has been a corresponding increase in demand for information gathering support by recommender systems. In our previous research, we developed a system that supports the collection of tourism-related information by utilizing the user's gaze information during web search and recommending search keywords related to tourism information that reflect the user's preferences. This is achieved by acquiring the text written at the gazing point on the screen [1]. In this study, we refined a methodology to determine a gazing point on a screen for the system. In addition, a new system is developed based on the preceding system to enhance the precision of personalization and incorporated a mechanism for acquiring image data. The modified system is reported in this paper.

    For the sustainable development in the agricultural sector, Japan is promoting the expansion of the area of conventional agriculture, i.e. environmental conservation agriculture that does not use pesticides or chemical fertilisers. In the paddy fields of the Hiki Hills region in northern Saitama Prefecture, reservoirs are formed at the head of eroded valleys to efficiently store rainwater and use it as a source of irrigation water for rice cultivation. The water storage system and the geographical location of the valley prevent the inflow of pesticides and chemical fertilisers. Paddy fields using the reservoirs are called 'yatsu-fields' in the region, and the farming form of yatsufields is known as yatsunuma agriculture. Yatsunuma agriculture was selected as a Japanese Nationally Important Agricultural Heritage Systems(J-NIAS)in 2023. However, paddy rice cultivation in valley rice paddies relies heavily on experience, as it cannot be controlled with pesticides and chemical fertilisers as in conventional cultivation. As a result, the retention rate of new farmers is low. In addition, Japanese farmers are rapidly ageing, and the amount of abandoned land in yatsuta fields is increasing year by year. Remote sensing (RS) has often been used in the agricultural sector, but has been limited to acquiring images at regional scales due to image scale limitations. The development of unmanned aerial vehicles (UAVs) has made it possible to acquire imagery at higher spatio-temporal resolutions than regional scales.

    This study aims to construct an evaluation model of nitrogen balance from a reservoir to a valley rice field by combining geo-informatics, chemical analysis, and biological analysis, targeting rice cultivated in Yatsuda (rice field in a valley) connected to a reservoir. First, the biomass of rice and weeds were obtained from UAV images, and the growth process of rice and weeds was grasped by organizing them in a GIS, and the biomass of rice and weeds was estimated separately to estimate the amount of nitrogen fixation in rice. Furthermore, the contribution of soil microorganisms to nitrogen fixation in paddy rice was qualitatively evaluated using soil microbial diversity activity values (BIOTREX), and a model was constructed to evaluate the nitrogen cycle originating from total nitrogen, including organic nitrogen supplied from reservoirs.

    “Structure and Function of the Human Body (Anatomy and Physiology)” is a basic subject for medical professionals, but many students have difficulty with it. The question of how to make knowledge of the subject take root and be converted into skills is a source of concern for teachers. Here, I 1) analyzed the use of Gagné’s nine events of instruction in lectures; 2) emphasized ways of relating to students and asking “loose” questions (pair-works and structured-group encounters (SGE)) by using a career counseling approach to lectures to promote job understanding; and 3) performed group work describing organs and blood vessels on a “diagrams of the body.” However, with the expansion of COVID-19 infection starting in FY 2020, the need arose to distance-teach Structure and Function of the Human Body. With “student engagement” in mind, the application of 1), 2), or 3) produced significant improvements in final exam marks, and the online use of Google Classroom produced marks that were equal to those produced by 1). I intend also to report the results of studies currently under way of the use of VR/AR teaching materials.

    This study was conducted to investigate rubrics: their usefulness in higher education and their evaluation by students. Specifically, the study compares the usefulness of returning rubric evaluations in two formats: face-to-face and using the Microsoft Teams (Microsoft Corp.) assignment feature. The survey was administered to female students enrolled in programming courses during 2018–2024, asking them to rate the rubric usefulness on a scale of 1 to 10. The analysis revealed no significant difference in assigned usefulness ratings between the two groups. However, results showed that establishing individual evaluation criteria contributed significantly to the perceived usefulness of the rubrics. Grade notifications and feedback had no marked effect on the usefulness ratings of the rubrics. These findings suggest that evaluation criteria must be defined clearly to ensure the effective use of rubrics.

    Uncertainty about the future is an obstacle to economic growth because it discourages consumption. Since 2022, prices have been rising due to the depreciation of the yen against the U.S. dollar. This makes life difficult for many Japanese. Are students worried about the future? The purpose of the first survey was to determine “the extent to which students are worried about their future. As a result, when asked, “Are you worried about your future?” 54.7% said they did, and 39.1% said they felt a little, for a total of 93.8%.Many students feel anxious about their future. The second survey was designed to find out if acquiring skills would reduce anxiety about the future. The results showed that 34.3% said it would decrease and 51.4% said it would decrease a little, giving a total of 85.7%, when asked if mastering economics would reduce their anxiety about the future. Many students are less worried about their future if they receive an education. Education plays an important role in Japan's economic growth. We will attempt to identify what kind of education decreases students' anxiety about their future.

    In our laboratory, four types of computerised large shogi varients are currently used for playing games. This paper describes the design and development of the game server among the various functions of the computerised large Shogi. The communication protocol does not include piece type information, but only the position coordinates of the pieces before and after a move. If the coordinates do not change before and after a move, it is assumed that an Igui function has been played, and the position coordinates of enemy pieces captured by IGUI are added after the normal data. As there is no piece type information, this protocol is easy to apply to various types of large shogi varients and is highly versatile. It is also useful in that it is flexible to rule changes.

    This study attempted to convert the arrival range and arrival time of lava flows marked on the volcano disaster prevention map, created in raster format, into a vector data format that can be analyzed in a GIS. Next, by superimposing the distribution of evacuation sites at the time of a disaster (lava flow) and people in need of assistance during a disaster (in this study, this refers to the elderly) on the information mentioned above, we attempted to evaluate whether the evacuation sites are appropriate for people in need of assistance during a disaster. The results showed that evacuation centers were adequately set up in areas with many people requiring assistance in times of disaster, and the number of people required for rescue operations (the total number of people aged 15 and over and those aged 65 and under) was sufficient. On the other hand, in suburban areas where the number of people in need of assistance during disasters is low, it was necessary to set up shelters appropriately and increase the number of rescue workers.
