There were misgivings that the teachers in charge might not have enough understanding of the true purpose of teaching "Information". To learn about the general attitude of those teachers, the research group of private schools in Osaka began a project, 'The Public Presentation Caravan', in which teachers who had already started using information tools opened their class to teachers from other schools and exchanged ideas. It may be deduced that the combination of the two forums for exchanging opinions, one is held on the internet and the other face to face, is important. Teachers' community exists on the point where these two environments meet. Through this project, we might suggest creating a new mode of teachers' community using a network will be indispensable for the new teachers training.

This study was executed to give a help in planning and implementing online learning. For this purpose this study investigated the effect of contents presentation types, levels and metacognition on concept map composition and learning process in online learning. Learning contents types were two, meaning-centered or context-centered. Contents levels were divided into two; basic or deficient. Metacognition was divided into two levels according to the scores of scale. Results showed that meaning-centered type(M=45.00, SE=1.97) got better scores in concept map than context-centered(M=34.71, SE=1.98), Presentation levels and metacognition had no significant influence on concept map. There were interaction effect(F=.002, p>.05) between presentation levels and metacogntion levels. The upper group in metacognition got higher score in deficient types whereas the lower group got higher score in basic type. In online learning process, learner's metacognition was an important factor to complement the contents' defect and lack.

Problem definition is as important as problem solving in decision making. Decision makers, however, tend to see problem partly or to define it unclearly. The researchers on decision making tend to lay a focus only on the Process of solving the given problem. This dissertation empirically studied the Problem diagnosis and definition in the decision making process. This study developed three kinds of DSS(Decision Support System) for the research and analyzed the effectiveness of the problem diagnosis and definition using DSS developed in this study. The three kinds of DSS are K-T(Kennel and Tregoe) DSS which is a method of table-styled information Presentation, and F-N(Fact-Net) DSS and C-E(Cause and Effect) DSS which are methods of graphic-styled information presentation. The empirical study was conducted twice; the pilot test and the main test. The samples of experiment are 218 students for the pilot test and 259 students for the main test. The author used K-T DSS and F-N DSS for the pilot test, and the revised K-T DSS and C-E DSS for the main test. A questionnaire survey method was included in the main test process The result of the study shows that the group using DSS in problem diagnosis and definition is more effective than the group not using DSS. A table-styled information presentation DSS, K-T, turns out more effective than a graphic-styled information presentation DSS, F-N, K-T DSS and C-E DSS showed no significant differences in the effectiveness in the main test. These results indicate that the use of DSS in the stage of problem diagnosis and definition is very effective and the methods and types of system design are a significant factors for DSS development.

In order to discern and classify high-quality slides, our research proposes a classification method that utilizes a knowledge structure containing information on the presentation slides. After analyzing whether our knowledge structure captures the content's quality information, we developed a classification method based on the knowledge structure produced from the analysis results. With the proposed method, we compared results classified by quality of presentation slides. Through this comparison, we verified that the slides in the high quality group could be classified and were able to retrieve high quality slides. The results show that, by utilizing the cognitive model of a knowledge structure, our method can increase the effectiveness of classification when search or recommendation is conducted mainly with high-quality slides.

This study tests the effect of recommended product presentation on consumers' usage intentions of a website, mediated by mental simulation. Mental simulation refers to perceptual experience, a more automatic form of mental imagery, initiated by exposure to the representations of objects. This study expects that when compliments of clothes (coordination items) are vertically presented online, consumers are likely to feel as if they wear the outfits due to the activation of mental simulation. The survey was conducted on 147 women in an age group between 20 and 40 years in a panel of an online survey firm. Data are analyzed using exploratory factor analysis and bootstrapping analysis by SPSS 20.0. The results show that when compliments (vs. substitutes) of clothes are presented, participants perceive a greater mental simulation. When compliments of clothes are vertically presented (vs. horizontally presented), mental simulation is also highly driven. In addition, mental simulation mediates the effects of online product presentation on consumers' usage intentions of a website. The findings of this study contribute to marketing strategies of online retailers in terms of how product recommendation can be offered to consumers with more psychological benefits.

Background No consensus has been reached regarding the outcome of management of local recurrence after transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction. This study demonstrated the presentation, management, and outcomes of local recurrence after immediate TRAM breast reconstruction. Methods A comparison was conducted among 1,000 consecutive patients who underwent immediate breast reconstruction with a pedicled TRAM flap (TRAM group) and 3,183 consecutive patients who underwent only modified radical mastectomy without reconstruction (MRM group) from January 2001 to December 2009. The presentation, treatment, and outcome including aesthetics and overall survival rate were analyzed. Results Local recurrences occurred in 18 (1.8%) patients (TRAM-LR group) who underwent TRAM breast reconstruction and 38 (1.2%) patients (MRM-LR group) who underwent MRM only (P=0.1712). Wide excision was indicated in almost all the local recurrence cases. Skin graft was required in 4 patients in the MRM-LR group, whereas only one patient required a skin graft to preserve the mound shape in the TRAM-LR group. The breast mound was maintained in all 17 patients that survived in the TRAM-LR group even after wide excision. The overall survival rate was 94.4% in the TRAM-LR group and 65.8% in the MRM-LR group (P=0.276). Conclusions Local recurrence after immediate TRAM flap breast reconstruction could be detected without delay and managed effectively by multiple modalities without reducing overall survival rates. Breast mound reconstruction with soft autologous tissue allowed for primary closure in most of the cases. In all of the patients who survived, the contour of their reconstructed breast remained.

Augmented reality (AR) is the technology in which a virtual image made by computer is integrated with the real world. Food is one of the most popular products purchased online. In this study, we investigated how the presentation of food images with AR affects purchase intention and user engagement. We hypothesized that purchase intention was increased more by AR food images than by static food images. We also examined whether user engagement mediates the relationship between image presentation format and purchase intention. To test this hypothesis, participants in one group saw AR food images, and participants in another group saw static food images on an iPad. All participants then answered questions about user engagement and purchase intention. As predicted, participants who saw an AR food image reported higher user engagement and higher purchase intention than did those who saw a static food image. The indirect effect of user engagement was also significant, and the link between image presentation format and purchase intention was fully mediated by user engagement. We also found that aesthetic appeal, one of the sub-factors of user engagement, fully mediated the link between image presentation format and purchase intention. Thus AR images of food images were aesthetically more appealing, which led to higher purchase intention. These findings suggest that AR technology can be used effectively as a way to advertise food.

The purpose of the study was to investigate the effects of task presentation methods (animation vs. picture) on verb naming abilities as a function of verb argument structures for normal elderly adults. Participants were categorized into the two groups: animation group(n=21) vs. picture group(n=21). Data for the animation group were from obtained from Sung and Choi (2012). Percent of accuracy for the verb naming task served as a dependent measure for statistical analyses. After the years of education was controlled as a covariate, a two-way mixed ANOVA was performed with the group as a between-subject factor and the argument structure(1-, 2-, and 3-place) as a within-subject factor. Results revealed that there was a significant interaction between the group and argument structure, whereas there were no main effects for either of the factors. The animation group performed better than the picture group for one-place verb, whereas the opposite pattern was observed for the three-place verbs. The results suggested that the presentation methods are one of the critical factors that influenced verb naming abilities in elderly adults.
