The measured signal is excellent for acquiring vehicle information on the road. Several studies have proposed identifying accident vehicles on the road by processing radar information. However, it is difficult to identify accident vehicles using a radar information in congested traffic since traffic radar information for accidents are almost the same as those for traffic jams. This study proposes a method to identifying accident vehicles based on an accident decision algorithm that distinguishes between congested and accident vehicles. Experimental results verified that the proposed method's detection accuracy exceeded 95%. We believe the proposed method will enhance future intelligent transportation systems.","PeriodicalId":309975,"journal":{"name":"2018 7th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127584879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As learning experience designers, teachers help students develop 21st century competencies via guided cognitive and social participation in designed learning activities such as games and gamified activities. In this qualitative case study, we explore teachers' design thinking in designing a lesson plan that involves the use of a card game designed for complex system understanding. Six teachers' thoughts about learning activity design are unpacked via the following activities: playing a card game, crafting a game-based lesson plan, and reporting their design thinking via semi-structural interviews. We discuss similarities in the teachers' views on game-based learning and the structure of their designed lessons, as well as implications of the study. This baseline study helps us map out how teachers think about learning experience design. Such understanding is critical for developing teachers as designers.","PeriodicalId":309975,"journal":{"name":"2018 7th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"1069 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132184508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Visitors to the area still more do not know about the area such as facilities and/or when and where to hold events in the area, means of transport to/from the area, and means of movements in the area if the area is too large for visitors to walk around, and so on. Although the main Web site of a local area such as a region, district, park or an organization usually works as a portal and provides the information above, the information is not always linked to with each other, in particular, on the map of the area except for facility names. Therefore people often feel difficult to find information related to their current or specified positions. Considering these problems, in this paper, we discuss an information sharing and recommendation platform specialized to a local area. The platform provides a variety of information associated with a map of the area, which means the information is linked with each other through the map. As a case study, we present \"ItoCamLife,\" which targets Ito Campus of Kyushu University. Ito Campus is one of four campuses in Kyushu University and the largest campus in Japan as one campus. More than 10 thousand people including students, members of faculty and staffs are commuting, and many visitors are also coming there especially when a big event such as university festival or a large scale conference is held. Therefore, Ito Campus needs such a platform of sharing and recommending information. In this paper, we present an overview of ItoCamLife, including its concept and current functions.","PeriodicalId":309975,"journal":{"name":"2018 7th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"210 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115754004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study is based on the participation of high school students; the participants were divided under two experimental conditions. The students were required to engage in one of two types of arguments: argumentation via SNS or face-to-face argumentation. Furthermore, the students were divided into small groups comprising three to five participants for each condition. Conversations and task performances were collected as the students were engaged in discussions. The transition probabilities between two talkers in the group, the number of utterances, and the task performances were analyzed. The results showed that the 3-person group discussed in a lively manner; however, it was difficult to obtain the consensus of this group. The 4-person group did not converse much initially but eventually conversed enough to be compared with other groups. It was also easy to obtain the group's consensus. The 5-person group conversed less, possibly due to social loafing. The findings suggest that a 4-person group is the optimal size for collaborative argumentation using SNS for educational purposes.","PeriodicalId":309975,"journal":{"name":"2018 7th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114577995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A time lapse camera and Bluetooth beacons are utilized and combined due to the requirement. As the result of evaluation in an actual factory, the automated system could detect and track both of a worker's location and its time period in enough accuracy and speed only by assigning an input movie data. The system rises alarm to its user about abnormal points in the data where the time period is more than the threshold value estimated statistically. In addition, the tracked worker's move is displayed by a red line in the movie frame for the cause-effect analysis. Furthermore, the tracked worker could be identified using a log data sent by beacon receivers in real-time.","PeriodicalId":309975,"journal":{"name":"2018 7th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117153221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To build our schema, as the first step we collect actual instances to be used and extract possible features to be included in the design of an ontology.
