{"title":"A Study on Junior-College Students' Maladaptive Cognition and Behaviour in Computer Programming Courses","authors":"Yen-Zhang Huang, Wan-Chun Wu, Ke-Fan Lin, Tien-Chi Huang","doi":"10.1109/CCOMS.2018.8463309","DOIUrl":"https://doi.org/10.1109/CCOMS.2018.8463309","url":null,"abstract":"Background and Purpose: The teaching objectives of senior vocational education emphasise professional skills training. In information technology and computer studies, computer programming is an extremely important foundation course for its corresponding professions. However, many studies on programming courses have pointed out that computer programming is a difficult subjectto learn; even undergraduates in information technology and computer studies are deterred by it. According to past research, learners' maladaptive cognition and behavior when learning computer programming tend to affect learning achievement. The purpose of this study is to explore the effects of the maladaptive cognition and learners' behavior in computer programming courses on their learning achievement. Methods: For that reason, this study applied a research survey to investigate the relationship between learners' maladaptive cognition and behavior and learning achievement in computer programming courses. The research participants were students in the information management department of technical and vocational schools who had previously taken programming courses. A surface strategy scale and a procrastination scale were adopted as research instruments to measure learners' maladaptive cognition and behaviour, respectively. Results: The results showed that learners' maladaptive cognition in the learning processes of computer programming courses had a significant, positive impact on their maladaptive behaviour and a significant, negative impact on their learning achievement. These findings indicate that learners' maladaptive cognition affects learning processes and effectiveness. For that reason, learners should reduce the incidence of maladaptive cognition during learning activities, so as to effectively lessen its negative impact on learning outcomes. The results of this study could be used as a reference for educators and educational researchers when designing curricula in the field of computer programming.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128656028","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}

Using pseudo-block quantization (PBQ) to construct a pseudo block for generating a prediction value yields a higher probability that a message can be embedded, and using two PGMs makes possible the use of both smooth and rough areas in the frequency domain. In this article, we apply the tools of context-value ordering and context-weight averaging to identify areas that are similar. In the experimental results, we achieve an overall optimization on Embedding efficiency (EE). The results show that our proposed scheme clearly demonstrates better performance than previous scheme.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122473836","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 resulting design is a cloud-based system that consists of two subsystems, back-end and front-end systems. The frontend system is for daily operations and is used by the staff. It comprises the point of sales (PoS) module and an attendance system. Meanwhile, the back-end system is intended for the manager or owner of the SME and contains an analytic module to support management in decision making.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"286 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123727930","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 adopted a least square temporal difference reinforcement learning algorithm for learning the controller. A new reward function is then proposed to better reflect the nature of the task. In addition, we also studied various factors which play important roles in the success of the learning.

This offers a dedicated challenge to ascertain the veracity of a digital image, especially when it is to be presented as a legal evidence. A number of techniques have been proposed to detect image forgery, albeit their respective efficacy depends on the type of forgery and/or the image features used to detect the forgery. Hence, their respective performance with respect to accuracy and execution time also varies. This paper focuses on the most frequently used image forgery, referred to as copy-move forgery. The work carried out in this paper is two-fold. First, a hybrid approach combining the existing block-based and non-block-based techniques of copy-move forgery is proposed. Second, the performance of the proposed technique is evaluated with different image features, including SIFT, SURF, MSER, MinEigen, FAST and Harris. The evaluation criteria comprising accuracy, precision, recall, F-1 score and execution time help to select a desired tradeoff between accuracy and execution time. The results proposed in the paper show that the proposed image forgery detection technique can successfully detect copy-move forgery with a high accuracy and reasonable execution time. Apart from this, the proposed technique also works fine with smoothed and brightened images.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124051279","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}
