Recently, organizations are making significant technology investments to build a centralized content management system. However, high-quality technology adoption can conversely create techno-stress in the user and cause negative behavior. The purpose of this study is to suggest the negative effects and mitigation directions of enterprise content management system(ECMS) related techno-stress. In order to verify the hypothesis, this study conducted a questionnaire survey on employees of organizations that adopted content management technology and conducted structural equation modeling. As a result of the analysis, ECMS related techno overload and complexity decreased the intention of continuous use of ECMS. But, internal communication activities reduced ECMS related techno stress and task-technology fit moderated the relationship between techno-stress and intention of continuous use of ECMS. The study has implications in terms of suggesting a strategic direction to minimize the negative causes of the use of content management systems.

In this paper, we analyzed through the EEG signals how musical stimulus affects learning activities. Musical stimuli were divided into sedative and stimulative tendency music, preferred and non-preferred music, and the learning activity tasks were divided into mathematics tasks and memorization tasks. The signals measured in the EEG experiments were analyzed with the power spectrum of SMR waves known to be related to human concentration. Those spectra used for quantitative comparison in this paper. As a result the power of the EEG signals was observed to be greater than the case where music was given as a stimulus. Regardless of the type of task, the power of the EEG signals was observed to be greater in the case of sedative tendency than in the case of stimulative tendency, and the power of the EEG signals was observed to be greater in the case of favorite music than in the case of unfavorite music. From these results, it is estimated that if the musical stimulus exists, in the case of sedative tendency music, and in the case of favorite music, concentration can be increased than in the relative case.

What does mean the statement that scientific reasoning is logical? In this study, we clarify the logical structure of the scientific explanation, prediction and the process of hypothesis testing. To simplify and identify the structure of scientific explanations and prediction more clearly, we used syllogism and presented various concrete examples. Especially, we showed that the logical structure of scientific explanation was well reflected in dynamics. Based on this analysis, it can be said that the deficit of students' understanding of dynamics is because that many scientific activities are focused on prediction rather than explanation. To explain the process of hypothesis testing, we reinterpreted the Wason's selection task as two stages: the process of prediction of experimental phenomena based on the presented hypothesis, and the process of the hypothesis testing based on the predicted experimental phenomena. And we suggested the reason of the logical fallacy of 'affirming the consequent' in science was because that many scientific relationships between the variables is one-to-one relationship, and compared this suggestion with the Lawon's multiple hypothesis theory. To check out the effect of content on the deductive reasoning, we reviewed some researches about psychology and psychology of science. And to understand the role of deductive reasoning in student's scientific activities, we reviewed researches about the analysis of students' responses in the task of conceptual change or evaluation of evidence and so on.

Objective : The purpose of this study was to investigate the effects of bimanual intensive training on Upper Extremity Function and activities of daily living in stroke patients. Methods : The subjects were 18 patients who were diagnosed with hemiplegic stroke. They were randomly assigned to bimanual intensive training group (n=9) and unilateral intensive group (n=9). Bimanual training group performed bimanual task and unilateral training group performed one hand task for 1 hour per session, 5 times a week, for 4 weeks. Chi-square test, Wilcoxon signed rank test, and Mann-Whitney U test were used for analysis. Results : The results showed that, upper extremity motor function and bimanual coordination were significantly improved in patients in the bimanual training group (p<.05). Additionally, the ratio of affected hand use and amount of use/quality of movement in the hemiplegic upper extremity in activities of daily living for patients in the bimanual training group were significantly improved (p<.05). Although the unilateral group improved motor upper extremity function and activities of daily living in the upper extremity (p<.05), it was not significantly different from that in the bimanual training group. In between-group comparison, bimanual coordination and ratio of the affected hand use in a day were significantly different (p<.05). Conclusion : It is reasonable to conclude that bimanual intensive training therapy is an effective intervention method to improve upper extremity motor function, and activities of daily living in stroke patients.

The activity of finding rules is useful for enhancing the algebraic thinking of elementary school students. This study analyzed the pattern activities of a finding rules unit in 10 different government-authorized mathematics curricular materials for fourth graders aligned to the 2015 revised national mathematics curriculum. The analytic elements included three main activities: (a) activities of analyzing the structure of patterns, (b) activities of finding a specific term by finding a rule, and (c) activities of representing the rule. The three activities were mainly presented regarding growing numeric patterns, growing geometric patterns, and computational patterns. The activities of analyzing the structure of patterns were presented when dealing mainly with growing geometric patterns and focused on finding the number of models constituting the pattern. The activities of finding a specific term by finding a rule were evenly presented across the three patterns and the specific term tended to be close to the terms presented in the given task. The activities of representing the rule usually encouraged students to talk about or write down the rule using their own words. Based on the results of these analyses, this study provides specific implications on how to develop subsequent mathematics curricular materials regarding pattern activities to enhance elementary school students' algebraic thinking.
