ABSTRACT
PID controllers are used in many applications and are considered an example of a fixed structure controller. For each specific system, the controller's PID parameters must be adjusted accordingly. Therefore, database-driven control, which automatically adjusts PID controller parameters using a large amount of experimental data, is attracting attention. Database-driven control is one of the methods that does not require model information. Therefore, in database-driven PID (DD-PID), the Jacobian of the system used for the steepest descent is unknown. In this paper, we propose an optimization method using gradient descent based on a local model of the system and confirm its effectiveness through simulation using the polystyrene reactor model as an example.

ABSTRACT
Modern marketing strategies that leverage technology to of-fer significant value for the client have replaced conventional selling techniques in recent years. A conversational agent or dialogue system presents an interactive computing product as a means of influencing people’s opinions. However, this expanding topic still had limits in the earlier study. To advance this field, the current experimental study incorporates new elements that are re-quired to enhance the ability to persuade and build a compelling case for product advertising. Research in the past has shown that emotional branding is essential to strengthen the customer’s engagement. Therefore, in this study, we created six contents, conducted an experiment with Japanese participants, and analyzed how to persuade them with emotional and cultural content using a sinking boat joke. A sinking boat joke is a joke about convincing people to jump into the water when a boat is ready to sink, which incorporates a cultural context. The experiment was conducted by recruiting Japanese students at a Japanese university. Contents were presented in a counterbalanced way. The goal is to ascertain which emotion works best for advertising, to investigate cultural differences, and to analyze the content effectiveness that successfully persuades the Japanese participants.

ABSTRACT
Retrograde analysis is a representative game analysis method that initially lists all legal positions and searches for the best move by analyzing from the final positions to the initial position. This method is effective for analyzing the games where the same position appears multiple times during sequential analysis from the initial position. However, it also has the drawback of requiring a huge amount of memory to enumerate the legal solutions. In this paper, we focus on the board game "Quoridor" released by Gigamic.

ABSTRACT
Recently, the necessity of integrated and comprehensive methodology for STEM (Science, Technology, Engineering and Mathematics) education is growing. In this paper, we propose an educational methodology utilizing the viewpoint of Equivalent Transformation Thinking (ETT) theory which has been proposed by Dr. Kikuya Ichikawa in 1955 as a principle of creativity. Especially, we show that the viewpoint of ETT is very useful not only for new technology invention but also for STEM Education in the sense that it deepens insights of the contents to be learned. Moreover, we suggest that the appropriate combination of the ETT viewpoint and the visual presentation such as animation and simulation by 3-Dimensional Computer Graphics (3DCG) will be more effective in motivating students to study further.

ABSTRACT
Car sickness often causes dizziness and discomfort that lasts for several days, accompanied by vomiting and headaches. Countermeasures and symptoms have been studied from various perspectives, but there are no comprehensive and unique countermeasures. In this study, data on motion sickness were taken from a random sample of drivers and passengers in a car. This study proposed a new measure to prevent motion sickness that does not depend on the performance of the car, and clarified that the rapid rotational movement of the head that occurs in the car is considered to be one of the causes of kinetosis.

pp. 247–252
ABSTRACT
The aim of this study is to develop a new tactile feedback method for myoelectric prosthetic hands. The sense of touch can be reproduced such as by vibrating actuators based on information from a sensor attached to the fingertip of the myoelectric prosthetic hand. This paper attempted to use delayed vibration feedback to create discomfort as a corresponding sensation to pain since a prior study has found that a time lag between sensory input and stimulation can cause discomfort. In the experiment carried out, we first examine the relationship between the delay time D and sensation in vibration stimulation. The experimental results indicated that discomfort occurs between D = 0.25 seconds and 0.65 seconds. Furthermore, to verify whether the proposed feedback method can be used to discriminate between normal objects and dangerous objects such as knives, we applied it to the haptic feedback of a prosthetic hand controlled by myoelectric signals. The results showed that the participant could recognize the difference in feedback and distinguish between the two types of objects with an accuracy of 95.0 ± 0.1%.

ABSTRACT
There are two main types of hula: classical hula ``kahiko'' and modern hula ``auana.'' Music, costumes, and accessories are essential to hula. Auana, in particular, is a dance set to music played with Western instruments and can express various aspects of mythology, history, and Hawaiian culture. The costumes and accessories worn by the dancers are designed to match the music. We thought that if we could freely design costumes and accessories on a computer and simulate the finished product, we would be able to create a design that was more in line with the dancer's image. This research focused on ornaments and developed a new CAD system as a result of basic research to develop a CAD system for designing "lei", one of these ornaments.

ABSTRACT
Miyazaki Prefecture is blessed with a rich natural environment, where many mushrooms have grown wild since ancient times, and the production of dried shiitake mushrooms ranks second in Japan after Oita Prefecture. Our partner, Sugimoto Co., Ltd., is a long-established company founded in 1970, and sometimes it is necessary to sort over 1 ton. Sorting is still done manually, making it very difficult for employees to sort. The purpose of this study is to determine the quality of shiitake mushrooms using deep learning and video image processing.

pp. 261–265
ABSTRACT
Reinforcement learning requires a lot of time for the agent to learn. Transfer learning methods can be used to shorten this learning time, but they have the disadvantage that it is not known which knowledge is effective in what kind of environment until it is learned. When users transfer knowledge, it is necessary to investigate the relationship between the transfer source and the transfer destination. This study proposes an adaptive criteria evaluation index that can determine this relationship in advance. In the simulation, we confirmed the effectiveness of the proposed method using several problem examples.

ABSTRACT
This study delves into Japanese for Specific Purposes (JSP) in Japanese language education, adapting to the evolving landscape of language learners’ preferences. I propose a self-learning system that leverages YouTube videos, catering to individual interests. Unlike traditional approaches, our system enables autonomous learning by allowing learners to select preferred Japanese YouTube videos, emphasizing necessary vocabulary and grammar. Using cooking-related videos as a case study, I analyze vocabulary usage through corpus-based methods. The analysis revealed that while a general vocabulary presentation showing a bilingual translation is sufficient for high-frequency words that commonly appear in multiple videos, it is required to present the characteristic words of each video along with meta-knowledge such as collocations of words, clichés, and technical terms. This study underscores the potential of digital resources for personalized language education, aiming to democratize access to language learning.

ABSTRACT
In 2016, we conducted a survey of high school students regarding science classes, and found that the percentage of high school students who answered that they "like science" or "science is important" was lower than for other subjects. However, more than 80% of elementary and junior high school students answered that they ``like experiments and observations.'' Additionally, a 2019 smartphone penetration rate survey found that approximately 90% of students use smartphones. Additionally, recent advances in VR technology have been remarkable. Based on the above, I thought that creating a simulation app using VR technology using smartphones could change the way high school students think about science classes. In this paper, we developed a new simulation application for science experiments. The subjects were asked to experience the newly created app and answer a questionnaire. The average score was 4 out of 5, which was poor. However, a problem was also discovered at the same time. The problem is that this app is a simulation app, so the user experience is not very good, so I would like to develop an app that is a little more user-friendly in the future. I would like to create apps for other fields while improving the problem.

ABSTRACT
In recent years, the efficient mobility of omnidirectional mobile robots is desired in the logistics industry. Hence, various types of rollers are installed in mobile robots. These include omnidirectional rollers, which are characterized with excellent omnidirectional mobility and are considered easy to control. Herein, considering that the side surface of the mechanism is circular, the kinematics of the mechanism assuming an arbitrary arrangement on this circle is derived. Previous research has evaluated the roller arrangement from the perspective of the speed efficiency of the drive roller. Meanwhile, this research focuses on a mobile robot equipped with three omni-rollers. Furthermore, focusing only on the translational speed of the robot, its motion efficiency is evaluated. The distribution of the robot’s translational speed is studied, the area of the region is used as the evaluation function, and its behaviors are analyzed.

ABSTRACT
Achieving expressive and human-like automated piano performances has proven challenging. This study proposes a deep learning system to infer expressive nuances from musical scores, addressing the limitations of traditional rule-based approaches. By leveraging neural networks to learn the mapping between scores and expert performances, the system automates the inference process, improving accuracy while enhancing efficiency. This novel application of deep learning shows promise for advancing automated music performance and enabling more artistically expressive renditions. The insights gained could have broader implications for computer-aided musical interpretation and synthesis.

ABSTRACT
The new concept of Photon Transport Transistor (PTT) as an optoelectronic amplification device has been proposed by the researcher at IBM Research Laboratory in 1989, as an alternative to Bipolar Junction Transistor (BJT). The PTT is composed by the opto-coupling of light emitting device and light receiving one. In this paper, we analyze the amplification function of PTT from the viewpoint of electronic equivalent circuit. For this purpose, we newly derive the AC (Alternating Current) based F parameter of the PTT emitter common circuit with fixed bias for AC small signal amplifier, using the VI characteristic equations of light emitting diode (LED) and photo diode (PD). Also, we discuss the amplification degrees of current, voltage, and power in the amplifier, using the derived parameter.
