Title: Discovery Security Vulnerability for the PyPI Packages Abstract: Python was the most popular language in 2019. In recent years, it attracts new users because of its fast-growing field of machine learning. However, software systems have an increasingly high number of packages, making the discovery of security vulnerabilities much more difficult. From a previous study, the python community does not react very fast to appearing vulnerabilities, and it takes more than 100 days on average to mitigate a vulnerability after its publish date. Moreover, the discovered vulnerabilities in Python packages are increasing over time, and they take more than three years to be discovered. In this research, we study how to use a fork to identify security vulnerability and update. A fork is a copy of a repository. Most commonly, forks are used to either propose changes to someone else's project. Our studied dataset is taken from two well-known data sources, Libraries.io and GHTorrent that we found the total number of fork projects are 40,955. language of the presentation: English | |||||||

Title: A Trust Model for Information Dissemination in Social Networking Services
Abstract: IInformation and communication technologies have developed rapidly, allowing users to provide unreliable information sharing inside social networking services (SNS). However, it is difficult for new users to distinguish the trustworthiness of the news on SNS, especially disaster-related news. To understand the process of how this information spreads, we consider a trust model of information dissemination towards disaster-related news in SNS. The existing trust model consists of four types of trust: identify-based, behavior-based, relation-based, and feedback factor. We consider a new trust type, information-based trust, which consists of semantic features and surface ones. The former represents the content accuracy, while the latter describes the post's exterior point of view, such as photo inclusion, logical degree, and popularity of a post. We develop an agent-based modeling simulation, investigating how fake news disseminates among SNS users. Language of the presentation: English | |||||||

Title: Toward the Perfect Stroke: A Multimodal Approach for Table Tennis Stroke Evaluation
Abstract: In table tennis, developing a consistent and proper stroke is quite challenging, perhaps even more so for non-professional players. To build consistent proper strokes for beginner players, there is a need to understand the stroke differences between beginner and standard players. In terms of table tennis applications, prior works used video-based method, or accelerometer sensor embedded in a table tennis racket, or infrared (IR) depth sensor for evaluating the stroke. However, there are certain challenges in these methods such as the having insufficient data to analyse a complete stroke, time-consuming and costly data collection, as well as using non-prevalent equipment. Hence, developing an ubiquitous way through readily accessible commercial devices would help beginner players to improve their performance. In this study, we (i) collect accelerator signals of standard and beginner players using consumer-grade products, and (ii) analysed the stroke consistency of both beginner and standard players. The results show the differences in the strokes between both kinds of players. These findings motivate us to further examine methods to help beginner players improve by providing guidance through procedural knowledge of a standard player's stroke, and implement applications for motor-skill instruction.

title:Non-touch tablet manipulation for the use of dietary therapy support system during cooking
abstract:Non-touch tablet manipulation for the use of dietary therapy support systems during cooking Abstract : Chronic kidney disease (CKD) is a disease in which the kidney function gradually declines.However, there are various burdens involved in implementing diet therapy, and our laboratory has been developing and creating a system to deal with these problems. In addition, since accurate measurement and cooking processes are important in diet therapy, the number of times a recipe is checked becomes larger than normal cook. However, during cooking, we do not want to operate the tablet directly by touching the screen because of hygienic reasons or because our hands are wet or dirty. Also, the tablet operation area and the cooking operation area overlap, which increases the number of false recognition when using non-touch. To solve this problem, we propose a tablet non-contact operation that can coexist with the cooking operation during cooking language of the presentation: Japanese | |||||||
