This study was conducted to investigate the perception of teaching consulting and dietary education of Home Economics teachers. The subjects consisted of 139 Home Economics teachers in Korea. The perceptions of Home Economics teachers on their teaching class were as follows: the teachers who had a lot of psychological burden on their open classes, 62.6%; who were satisfied with their teaching, 29.5%; who had been teaching consulting, 40.3%; consulting is needed in order to improve the quality of instruction, 46.8%; who wanted to receive teaching consulting, 46.1%. who wanted to receive teaching consulting excellent colleagues, 76.3%. The most of the Home Economics teachers had a positive attitude on the teaching consulting. The perceptions of teaching strategies of dietary teaching classes were as follows: using audio-visual materials for students concentrate, 47.5%; observing the students reactions and feedback for individual variation, 73.4%; descriptive class for main teaching method, 58.3%. The difficulties of teaching dietary class were as follows: total mean, 2.60/5.00; considering individual differences, 3.26; involving students in activities, 3.11; selection of teaching media, 2.88; production of media, 2.88; planning teacher and student activities, 2.85. Home Economics teachers have to lead dietary education in society and schools but they feel a lot of psychological burden on opening teaching class. Therefore Home Economics teachers are recommended to devote consistent efforts to strengthen teaching ability through the analysis of teaching ability, teaching reflection, consulting and actual performance of self-supervision.

The purpose of this research was to optimize electric current production of sediment microbial fuel cells by injecting glucose and to investigate its impact on microbial communities involved. It was shown that injection of proper concentration of glucose could increase electric current generated from sediment microbial fuel cells. When 1,000 mg/L of glucose, as opposed to higher concentrations, was injected, electric current increased up to 3 times. This increase is mainly attributed to the mutual relationship between fermenting bacteria and exoelectrogenic bacteria. Here the organic acids generated by fermenting bacteria could be utilized by exoelectrogenic bacteria, removing feedback inhibition caused by the organic acids. When glucose was injected, the population of Clostridium increased as to ferment injected glucose. Glucose fermentation can have either a positive or negative effect on electric current generation. When exoelectrogenic bacteria may readily utilize the end-product, electric current could increase. However, when the end-product was not readily removed, then detrimental chemical reactions (pH decrease, methane generation, organic acids accumulation) occurred: exoelctrogenic bacteria population declined and non-microbial fuel cell related microorganisms prospered. By injecting a proper concentration of glucose, a mutual relationship between fermenting bacteria, such as Clostridium, and exoelectrogenic bacteria, such as Geobacter, should be fulfilled in order to increase electricity production in mixed cultures of microorganisms collected from the aquatic sediments.

According to many researches on brand management, the decision makings on brand marketing should center on the brand identity. Based on the brand management theory, Brand Identity-based OSMU Strategy has been suggested, in which the decision makings for culture content's OSMU should be focused on the brand identity of content to maximize the brand equity. In this study, the effectiveness of suggested brand identity-based OSMU strategy model is empirically studied, together with the effect on the brand equity. The study on the consumer's attitude toward the Harry Potter T-shirt with the associations of 'magic, courage and confrontation against evil' proved that consumers respond more favorably in terms of their recognition of the fit-to-content, preference and perceived quality. With this result, the positive effect of brand identity-based OSMU on consumer attitude is verified. On the other hand, the study on the effect of brand identity bearing T-shirt on brand equity did not support the hypothesis that the brand identity-based OSMU has the positive feedback effect on the brand equity of culture content. Still, while the brand equity is established through the long period of time with consumer's consistent experience on the certain culture content, the effect of brand identity-based OSMU on brand equity has a room for further discussion and research. While the ultimate goal of marketing is to create the power brand with high brand value, the further discussion on the effective culture content OSMU strategy to create a power brand is needed.

This study compares and analyzes the characteristics and effects of various educational contextual variables according to students' achievement level and gender groups based on the results of PISA 2015 science domain. PISA 2015 included additional variables about teaching-learning and affective characteristics in the field of science, because science was the main domain of PISA 2015. The results of the mediation analysis using a multiple group structural equation model showed that the environment and strategy for the teaching and learning had a positive effect on the affective characteristics, and also positively affected science achievement through the mediator of the affective characteristics. Particularly, the environment and strategy for the teaching and learning was the most effective in improving the affective characteristics for the low achievement group. It was found that the difference of the mediated effect between achievement level groups was statistically significant, but that between male and female students was not. Therefore, the appropriate the environment and strategy for the teaching and learning will need to be emphasized consistently to improve students' cognitive and affective achievement. The implications and suggestions of these results were discussed.

This study was designed to examine whether the self-directed learning method could improve self-directed learning readiness and the effects of academic achievement level. Self-directed learning readiness was investigated among 63 first-year Medical Terminology undergraduates in the C area. A repeat measurement variance analysis of the general linear model was conducted to evaluate the effects of improving self-directed learning readiness according to the general characteristics and level of academic achievement, while a regression analysis was performed to identify the factors affecting self-directed learning readiness. Self-directed learning readiness increased from 177.3 to 180.8 for those under 18 years of age, and 192.9 to 196.5 for those over 19 years of age (p<0.05). After the team activity, the overall self-directed learning readiness was improved, and both high- and low-achieving groups showed statistically significant improvements (p<0.05). The environment surrounding learners was confirmed to have a positive effect on improving self-directed learning when given the right degree of self-directed learning and appropriate feedback. The study results are expected to form basic foundation material for professors and class designers who want to draw self-directed learning skills from memorizing subjects.

Let me introduce a teaching method to improve practice capacity in dental laboratary work. I applied theories of layers of modeling and reflection constituting cognitive apprenticeship and peer tutoring to my class. At internet uploading a file showing a practice procedure a week before the class of a course, I let students preview it. During the class I demonstrated the practice procedure in front of students. A superior student and an inferior student paired according to the previous practice grade and a feedback between a peer tutor and a peer tutee was activated. Late in the class, a student self-evaluated his own practice result and had a check of a professor. Finally he compared his own practice result with that in the file uploaded at internet and reflected. This teaching method led to improvement in students' satisfaction and efficiency of learning.
