While defining the key points for the global education, it is proposed that there should be a need for the learning environment to nurture the problem-solving skills in teams consisting of global students to tackle with the issues in the global society. The proposed courses here are based on the pilot study courses to set a benchmark as well as on a series of discussions between Kansai University and ASEAN universities, especially, universities in Taiwan and Malaysian Putra University. These courses focus on Communication to Build Trust through Empathy in the Society and Social Entrepreneurship, e-Culture & e-Agriculture. These courses make a heavy use of the state-of-the-art ICT and rich media Technology. It is planned that the courses will be fully launched in the fall semester of the academic year 2017 among the allied universities.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126530456","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}

We show that the encoded bits of the ACELP codebook excitation pulse positions are more appropriate for message hiding than the encoded bits of other speech parameters. The score of an imperceptibility assessment shows that the perceptual evaluation of speech quality (PESQ) value is reduced slightly, by 0.112, compared to that of a carrier voice that is not inserted information. Evaluation reports present that our proposed scheme can attain complete invisibility and obtains a message-hiding volume of on average 400 bps for a 5.3 kbit/s coding rate. Objective quality measurements verify that our proposed hiding scheme can achieve an inaudible distortion in the occult-speech quality.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134333426","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}

First, a blur detection based on Structural Similarity (SSIM) is proposed to identify whether an image contains a blurred background and the sharp foreground objects can then be extracted. The visual saliency is further calculated to help remove insignificant boundaries. Some pre-defined rules are employed to determine more appropriate cropping limits. If further reduction of resolution is necessary, the resulting image after cropping will be scaled directly to the target size. The experimental results show that the proposed method is computationally efficient and the promising results can be achieved in still images and video frames.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"325 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133189235","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 results from the use of the open data based analysis tool for site selection reveal the following: The areas with extremely small outliers are areas with gaps in consumer passion, i.e. unsaturated market sites; The areas with extremely large outliers are central areas with high degrees of consumer passion, i.e. sites for refined business strategies; and Markets with development potential all fall in areas with large populations or bustling areas.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134599151","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 broadcasting, over-exposed regions in image/video can be detected and corrected prior to sending them to consumers. However, the current detection of over-exposed regions is sometimes inaccurate. The detected over-exposed regions are susceptible to noise and scattered. In this paper, we proposed detecting over-exposed regions in images using L2 regularized logistic regression (LR). Over-exposed regions are accurately detected using several novel features in the LR model. These include modeling the characteristics of over-exposed regions as clusters rather than isolated pixels. In addition, overexposed regions are also characterized by both intensity and chrominance pixel values. Optimal parameters for the classifier are obtained by performing training on different scenes. The experimental results show that the detected over-exposed regions are more spatially connected and perceptually accurate compared with current techniques with comparable fast processing.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114173508","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 objectives of this research are to try the flipped classroom learning in the course and to evaluate the satisfaction of the students in the course. The aim of the research is to determine the suitability of the flipped classroom learning on the course, including the advantages and limitations of such learning method. The learning management system is Courseville and the teaching materials are Thai lecture videos, and English documents of the course instructor. The research mythology is to collect data from students enrolled in the course, whose data are composed of the behavior of the students, students' test scores, and the term project scores. Moreover, the collected data from the questionnaires are used for analyzing the students' satisfaction of the flipped classroom teaching. The research result shows that the flipped classroom learning is suitable for the object-oriented analysis and design course with the aggregation of 90 percent of students. In addition, the 85 percent of students are satisfied with the flipped classroom learning in this course.","PeriodicalId":440018,"journal":{"name":"2017 10th International Conference on Ubi-media Computing and Workshops (Ubi-Media)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123663003","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}
