ABSTRACT
Creating a duty roster that meets all the various requirements of nurse rostering is extremely challenging. Consequently, many researchers have studied nurse rostering. Despite these efforts, the shift schedules generated by these studies are often not practical in their initial form, as they require adjustments to accommodate various constraints and evaluation criteria. Thus, we have proposed a method for revising duty roster using Q-learning in a constructive nurse rostering. This paper explores the potential for developing a practical duty roster that accommodates nurses with varying duty plan valuations. This involves considering each nurse's lifestyle. Additionally, we visualize the duty plan valuations of the revised rosters we obtain.

ABSTRACT
This study explores the implementation of intrusion detection solutions, specifically Snort, in industrial control environments that use network segregation as a security measure. Unlike traditional deployments at gateway ports, our research integrates Snort directly within isolated networks, customized with specific operational technology (OT) rules. The effectiveness of this system was tested using the TWISC@NCKU Critical Infrastructure cybersecurity testbed in Taiwan. This findings indicate that this strategic approach can successfully detect anomalies in network traffic, effectively addressing the common challenge of limited monitoring in segregated network environments.

ABSTRACT
The proposed system utilizes facial recognition technology to detect and track the user, eliminating the need for physical effort in pushing a shopping cart. Additionally, the robotic trolley is equipped with an ultrasonic sensor that estimates the distance walked by the user, providing them with valuable information about their physical activity levels during the shopping trip. The implementation of this system leverages the OpenCV computer vision library within the Python programming framework, enabling the integration of the facial recognition and distance estimation capabilities. Evaluation of the developed prototype has demonstrated significant improvements in the quality of life and independence of elderly individuals, as they can now navigate the shopping environment with greater comfort and ease. This innovative robotic shopping companion represents a promising solution to enhance the shopping experience for the aging population, addressing their unique needs and empowering them to maintain their autonomy, well-being, and public health during their daily activities.

ABSTRACT
With the recent emergence of Amazon warehouses and service robots at airports and hotels, it is believed that we will enter an era in which humans and robots will struggle to coexist. Elementary and junior high school students need robotics education, which sparks their interest at an early stage. In response, higher education institutions are actively working on robot education, but most of them focus on online tracing using microcomputers. In this study, students from a technical college organized a workshop for third-year junior high school students to teach robotics about maze exploration. The lecture was evaluated by means of a questionnaire

ABSTRACT
Since Russia invaded Ukraine in 2022, information related to the invasion has increased. This information is spread through social networking services and TV programs. This study proposes a framework for a disinformation game system. In the game, a player spreads disinformation. In particular, we discuss topics related to the Russo–Ukrainian War in February 2022. The game system provides players with mental immunity to disinformation by simulating its spread. Three experiments were conducted in this game. In experiments on the proposed game, people gradually lost their resistance to disinformation by repeatedly receiving disinformation.
