Title: Mitigating Smartphone Addiction and Fostering Cognitive Shifts through Narrative-based Gamification

Co-author: Jun Iio (Professor, Faculty of Global Informatics)

Overview: This study proposes a method to mitigate smartphone addiction using narrative-based games. Specifically, a game designed to reduce smartphone dependency was developed using Twine, followed by experiments and analytical evaluations of the results. (Presented at WSSM-2026)

Presenter: Narumi Kiyooka (Fourth-year student, Faculty of Global Informatics)

Title: An AST Based Static Analysis System for SQL Anti-Pattern Risk Quantification and Inline Improvement Suggestions

Co-author: Masaki Kohana (Professor, Faculty of Global Informatics)

Overview: While data utilization and cloud migration have expanded rapidly in recent years, platforms often adopt a pay-as-you-go pricing model, and inefficient SQL (Structured Query Language) queries can lead to increased costs. To address this issue, this research aims to develop a system that detects query structures from input SQL, evaluates associated risks, and prompts users to make improvements.

Title: Shift Generation Using a Nurse Scheduling Model for a University Festival

Co-author: Masaki Kohana (Professor, Faculty of Global Informatics)

Overview: This research aims to develop a shift scheduling system that supports the smooth operation of events for organizations with limited human resources. Manual scheduling often imposes a heavy burden on organizers due to complex constraints, such as staffing requirements and interpersonal compatibility. By applying a Nurse Scheduling Problem (NSP) framework and mathematical optimization, this system automates optimal shift generation to significantly improve operational efficiency.

Title: Development of a PMV-Based Thermal Comfort-Oriented Outfit Recommendation System

Co-author: Masaki Kohana (Professor, Faculty of Global Informatics)

Overview: Selecting appropriate clothing based on weather conditions is important in daily life, yet choosing outfits while taking into account personal wardrobes and planned activities can be challenging. This study developed a system that suggests thermally comfortable outfit combinations based on users' registered clothing items, weather information, and activity types, enabling personalized outfit recommendations tailored to daily situations.

Title: A Restaurant Search System for Food Allergy Co-author: Masaki Kohana (Professor, Faculty of Global Informatics)

Overview: For individuals with food allergies, finding suitable menu options when dining out can be a considerable challenge. This study developed a system that allows users to select specific allergens and search for restaurants that offer dishes free from selected allergens, providing allergy information and integrated maps. The study demonstrated the utility of search functionalities tailored to food allergies that are not commonly available on existing restaurant review platforms. (Presented at WSSM-2026)

Title: Development of a Real-Time Conversation Support System for Intercultural Online Exchange: Speak Ease

Co-author: Jun Iio (Professor, Faculty of Global Informatics)

Overview: While intercultural exchange helps foster language skills and cross-cultural understanding, language barriers often limit participation. This study developed "Speak Ease," a conversation support system equipped with topic and vocabulary suggestions as well as real-time transcription. Experimental results showed that while overall speech volume remained unchanged, vocabulary diversity improved significantly, highlighting the system's effectiveness as a tool for supporting intercultural exchange. Further evaluation of the system is planned. (Presented at WSSM-2026)
