The purpose of this study was to verify the effect on learning using YouTube. The relationship between expectations, cognitive attitudes, emotional attitudes, and reuse intentions was explored. The results are as follows. First, the factors affecting the intention to reuse YouTube were emotional attitude and expectation. cognitive attitude did not show any significant effect. Second, cognitive attitude and expectation agreement were significant variables in emotional attitude. cognitive attitude was identified as a major factor affecting emotional attitude. Third, expectation agreement was found to have a significant influence on cognitive attitude. Therefore, expectancy is an important factor in identifying cognitive attitudes. In particular, the satisfaction of expectations after experiencing a new technology or system, such as YouTube, affects the cognitive attitude. Finally, the main findings of this study were that cognitive attitude was not a variable affecting the intention to reuse YouTube. The reason for this is that YouTube is used as a medium of interest, and it is not used as a medium for searching the main data source for learning. Therefore, in order to activate YouTube learning, it is necessary to convert recognition into YouTube for learning rather than YouTube for play.

The expectation and confirmation emerging as one of problem-solving strategies in the elementary school is a strategy that does not limited in the elementary school but used in the middle and high school. This strategy inevitably requires a process of adjustment that affected by the earlier expectation. Such an adjustment raised expectation and confirmation to one of effective problem-solving strategies. The adjustment is especially important to carry out the strategy effectively. The aim of this study was to conduct basic research on cognitive characteristics appearing to students when they carried out the expectation and confirmation strategy. We investigated and analyzed this in term of adjustment of expectation. To do this, we examined 50 5th graders' response in three kinds of word problems and interviewed with 4 participants who is using the expectation and confirmation strategy. The interview was conducted by using the items or solutions used in the test. From this, we tried to check students' cognitive characteristics and recognition on it's value. Furthermore we proposed the pedagogical implications associated with these results.

Reliable detection of primary user activity increases the opportunity to access temporarily unused bands and prevents harmful interference to the primary system. By extracting a global decision from local sensing results, cooperative sensing achieves high reliability against multipath fading. For the effective combining of sensing results, which is generalized by a likelihood ratio test, the fusion center should learn some parameters, such as the probabilities of primary transmission, false alarm, and detection at the local sensors. During the training period in supervised learning, the on/off log of primary transmission serves as the output label of decision statistics from the local sensor. In this paper, we extend unsupervised learning techniques with an expectation maximization algorithm for cooperative spectrum sensing, which does not require an external primary transmission log. Local sensors report binary hard decisions to the fusion center and adjust their operating points to enhance learning performance. Increasing the number of sensors, the joint-expectation step makes a confident classification on the primary transmission as in the supervised learning. Thereby, the proposed scheme provides accurate parameter estimates and a fast convergence rate even in low signal-to-noise ratio regimes, where the primary signal is dominated by the noise at the local sensors.

Objectives: This study aimed to develop nutrition education program for consumers to reduce sodium intake based on social cognitive theory (SCT). Methods: The main factors of SCT related to low sodium diet were investigated by using focus group interview (FGI) with 30 women who participated in consumer organizations. Results: The main target groups for the education program were housewives (H), parents (P), and the office workers (OW), for which we considered their influences on other people and the surroundings. According to the results of FGI, in carrying out low sodium diet, 'positive outcome expectation' were prevention of chronic disease and healthy dietary habit, and 'negative outcome expectation' were low palatability of foods, difficulty in cooking meals, and limited choice of foods. The contents of the program and education materials were individualized by each group to raise self-efficacy and behavioral capability, which reflected the results of the FGI. The program included 'salt intake and health' to raise positive outcome expectation. For improving the ability to practice low-sodium diet, the program contained the contents that focused on 'cooking' and 'food purchasing' for H, on 'purchasing and selection of low-sodium food with the children' for P, and on 'way of selecting restaurant menu' for OW. Also the program included 'way of choosing the low-sodium foods when eating out' with suggestions on sodium content of the dishes and snacks. Further, 'dietary guidelines to reduce sodium intake' was also suggested to help self-regulation. Conclusions: This nutrition education program and education materials could be utilized for the community education and provide the basis for further consumer targeted education program for reducing sodium intake.

'I'his study investigated students' attitude toward mathematics. and how behavior/cognitive training affects level of math anxietv and level of math achievement. Subjects were all the freshmen attending Taejon Science High School, and they were given Mathematics Attitudes Scale and Attributional Style Questionnaire prior to and post training sessions. Twenty out of 84 freshmen voluntarily participated in nine sessions of training program. Participants were asked to do self-evaluation. Math achievement was measured prior to and post training. and was compared between two groups. Training program utilized behavior/cognitive approach. such as understanding one's feeling through muscle relaxation, breathing and meditation; modifying negative attributional style; imitating effective cognitive strategies for math problem solving, and so on. 'I'he result shows that students' math confidence in general was relatively low out of expectation, a nd they perceived teachers not supporting their math abilities :IS much as expected. On the other hand, students in general had strong math achievelment needs, and considered math utility very high. Sex difference was seen in the attitude toward female math abilities, to result that female students had more positive perception than male students. Female students of 'I'aejon Science High School seem free from conventional idea about female abilities including theirs. Participants' ~attitude change was compared with non-participants. and participants showed statistically significant change in their math confidence, and also in their math achievement. Participants had much higher math confidence and ~achievement than non-participants. And, they showed increased level of perceiving teachers' expectation. more realistic in needs, and more involvement in math. Math achievement was found positively related to math confidence, and participants' math achievement change was explained by their belief in math utility. Not only training program effect hut also participants' voluntary involvement and teacher\ulcorner' support of the program and participation seem to increase their math achievement. Based upon the result of study it was suggested that behavior-/cognitive training program be provided along with academic curricula for gifted students of Korea to help their emotional and psychological development enhance the efficacy of their cognitive learning.
