Separation logic (SL) is extensively employed in verification to analyze programs that manipulate dynamically allocated memory. The entailment problem, when dealing with inductively defined predicates or data constraints, is undecidable for SL formulas. Our focus is on addressing a specific fragment of this issue, wherein the consequent is restricted to clauses of some particular form, devoid of inductively defined predicates. We present an algorithm designed to determine the validity of such entailments and demonstrate that the problem is decidable and ExpTime complete under some conditions on the data theory. This algorithm serves the purpose of verifying that the data structures outlined by a given SL formula (the antecedent) adhere to certain shape constraints expressed by the consequent.

Tourism has always been an important economic sector around the world with millions of tourists travelling every year. As the world emerges from the COVID-19 pandemic, the tourism industry is rapidly recovering, and it is projected that global traveler numbers will reach 90% of pre-pandemic levels by the end of 2023. While it is a significant contributor to global economy, it is also a great source of danger for tourists. Research studies have found that tourists are vulnerable to a variety of dangers and risk, including injury and death, while visiting attractions around the world. Compared to domestic populations, tourists face up to 16 times higher risks of fatalities from road accidents, drowning, falls, and crimes. It has been found that in a study done in New Zealand, an estimated 20% of overseas visitor injuries and 22% of fatalities are by tourism related activities. As such, we have developed a mobile application called Voyager is focused to help users be more informed about the dangers and safety culture of their travel destinations. The Voyager aims to help tourists identify safe locations, understand local law and safety culture. By providing this information, the Voyager aims to minimize the risks associated with tourism and enhance the overall travel experience for users.

The existing educational products of parent-child interaction have lost the two-way reciprocal nature of parenting education. The Bioecological Theory concept of interaction between multi-layer systems is consistent with the theory of Product Design Theory. In view of this, the purpose of this study is to explore the potential links between these two areas and to explore whether Bioecological Theory can help improve product innovation for children and parents. We conducted a case study with an industry-leading provider in Shenzhen. In the first stage, we distributed questionnaires to 99 parents of K6-K9 children to understand their views, daily interactions with children, communication styles, and preferences for learning devices. In the second stage, 12 children and their parents were selected from people in the first stage of the study for Non-participatory observation. From the data obtained, we established a framework to describe the interaction model based on the concept of interaction between multi-layer systems of Bioecological Theory, and sorted out an improvement strategy 'Dynamic Interaction, Two-way Reciprocity, Long-term Participation, Adaptability'. These outputs were subsequently evaluatedwith company experts and received positive feedback. This study affirms the two-way reciprocal and dynamic development of parent-child interaction. The Bioecological Theory reveals that the complex interaction between different systems needs to be considered in the design of parent-child interactive education products. At the same time, it also provides a reference for how to correctly apply Bioecological Theory in the study of parent-child relationship.
