To summarize the big data generated from a huge amount of micro behaviors into the useful behavior features for constructing a good CMC competence forecasting model, this study developed the learning micro-behavior classification structure according to the collected data features and the concept of CMC. An effective method for constructing a high correctness and stableness CMC competence forecasting model was proposed and examined. Besides, the effects of learning situations on the accuracy of the CMC competence forecasting model were also discussed.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116764190","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}

In order to do this effectively, the ability to share information among medical facilities will be critical. A common method of sharing information between medical facilities is through the use of patient referral documents ( Form 11 ) . In the present study, in order to standardize information sharing for secondary applications other than referrals, the contents of 1,000 patient referral documents were analyzed and categorized. As a result, data specifying reasons for referral were structured into 4 layers, from which 18 categories were derived. Data from the medical history section were sorted into 8 categories and 33 subcategories. These findings will be useful when creating a medical information sharing system compliant with Form 11.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122680122","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}

However, after 3.11, the Japanese government was forced to change its energy policy and now the government is putting an emphasis on utilizing renewable energy. Among types of renewable energy, small hydropower generation is winning attention because it provides many advantages such as being a chisan-chisho (produced locally and consumed locally) typed energy, produces little Greenhouse gas, constantly produces energy, having many potential sites around Japan, and having a long life time. This study selected Kyushu Hatsuden, a new corporation in Kagoshima Prefecture established by local firms and influential people to promote small hydropower generation in the prefecture as a case study. This study conducted a socio-economic analysis using several analytical methods. The results of the series of analyses showed that the small hydropower business of Kyushu Hatsuden has a positive impact on the local community.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122052999","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}

Purpose of tick size reduction is to improve liquidity. Tokyo Stock Exchange (TSE) reduced twice its tick size in 2014. The first time is called phase 1 (P1). Also, the second time is called phase 2 (P2). In previous study, Amihud showed the relationship between stock return and illiquidity. If stock exchanges improve liquidity due to tick size reduction, there is the possibility that stock return will decrease. But Pachare and Rainer find no impact on abnormal return (AR) and cumulative abnormal return (CAR). So, in this paper, our purpose is to investigate long term AR and CAR. As a result, we got following four results. First, there are some positive and negative AR days in P1. Second, there are some negative AR days in P2. Third, CAR is positive in P1. Fourth, CAR is negative in P2.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129728848","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}

Successful DX requires not only technology, but also an understanding of the importance of business agility. In addition, without careful traceability, software engineering projects can be not based on business and social values. To address these issues, we categorize useful methods, practices, and models in software development and operations that make connections and traceability from business ideas incorporating business agility to software products, services, and user experiences. Then we propose a typical value-driven process stemming from business and social perspectives as new software engineering necessary for the DX era. We also categorized these items of the value-driven process through the mental factors of cognition, affective, and conative to analyze the process.","PeriodicalId":188870,"journal":{"name":"2020 9th International Congress on Advanced Applied Informatics (IIAI-AAI)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123915804","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}

Various documents are created through these processes, which are related each other as software configuration. Beginners such as student cannot understand mutual relationship within the software configuration well. Considering this situation, we propose and develop a visualization tool named VRale-SCM which shows these documents in 3D virtual reality space. The tool visualizes mutual relationship among the documents so that students can navigate the documents through the relationship. Students are thus expected to clearly understand the relationships by this tool. In this paper, we focus on the coding process. VRale-SCM visualizes relationship between Java source code and the parse tree.
