Quantitative microbial risk assessment (QMRA) analyzes potential hazard of microorganisms on public health and offers structured approach to assess risks associated with microorganisms in foods. This paper addresses specific risk management questions associated with Staphylococcus aureus in kimbab and improvement and dissemination of QMRA methodology, QMRA model was developed by constructing four nodes from retail to table pathway. Predictive microbial growth model and survey data were combined with probabilistic modeling to simulate levels of S. aureus in kimbab at time of consumption, Due to lack of dose-response models, final level of S. aureus in kimbeb was used as proxy for potential hazard level, based on which possibility of contamination over this level and consumption level of S. aureus through kimbab were estimated as 30.7% and 3.67 log cfu/g, respectively. Regression sensitivity results showed time-temperature during storage at selling was the most significant factor. These results suggested temperature control under $10^{\circ}C$ was critical control point for kimbab production to prevent growth of S. aureus and showed QMRA was useful for evaluation of factors influencing potential risk and could be applied directly to risk management.

As childhood obesity and nutrition imbalance emerge as social issues in South Korea today, the development of education materials on diets and nutrition has become important and has been attempted in diverse ways. The present study was conducted on early elementary school students with the objective of establishing directions for the design of personalized nutrition education materials that can promote a proper, balanced diet for children through application in daily life of knowledge acquired from self-learning linked to nutrition education that is taking place in their schools. For this purpose, a review of previous theoretical literature on nutrition education for early elementary students was performed. Survey questions were formulated based on the advice of field experts in medicine, education, and design and the survey was conducted among 110 children from 1st and 2nd grade in two elementary schools, one in Seoul and the other in Changwon. The results obtained from the user evaluation suggested that the early elementary school students showed positive reaction to nutrition education, had preference for the type of learning using multimedia-based contents and quiz activities, were willing to learn about calorie-adjusted meals, preferred the Gothic typeface and orange and green colors. Furthermore, they showed positive opinion on the use of numerical surveying method and pictorial style similar to actual appearance in connection with nutrition-related information representation. and preferences regarding learning styles and design elements

According to the development of internet with Web, WBI has greatly influence on the present educational society. However, it is difficutly to design the web of the dynamic motions of graphics or animation using general programming technique based on high or low level language. Recently, Mecromedia Company supported a tool that is called Authoware which is the leading visual rich-media authoring solution for creating Web and online learning applications, to solve the problem easily. In the paper, using the the Authoware we tried to develop a web page about tidal variations due to sea level change and intertidal zone variations using the Authorware 5.1. To do this, we used the ocean survey data of Iho beach and the tidal level data based on Tidal Tables of Cheju harbor. The results showed that the Authorware was very useful to construct the simulation of tidal phenomena on web. Therefore, the Authorware can be applied to the simulation related with animation and dynamic motions for the other WBI objective.

With the growth of the Internet, web-based cyber education is progressing from the text-based to the hyper-based including multimedia, and from one way of simply giving the contents to the learner to another way of providing mutual interaction between the instructor and the learner. For this, there uses the RIA-based dynamic application and multimedia. RIA, which is the new paradigm on the web, provides the learners with more effective and rich contents. For developing a cyber education system, if we use the existing web languages, a large amount of effort is needed. But if we use the RIA-based paradigm, we can remarkably reduce the effort. Also, in developing a new web-based cyber education system the RIA paradigm makes the learners to satisfy their demands, and in developing the system providing the interaction the paradigm gives us the way minimizing the time and effort. In this paper, we compare and evaluate the efforts in developing the RIA based education system with the Non-RIA based education system.

The educational effect of movie is very high. This paper suggests a practical scheme applying multimedia materials to some subject classes. At present film education consists of 3 methods, integrated method, regular method, and professional method in the 7th curriculum. The simplest method is integrated method. Most previous researches tried to apply to middle or high schools, or only one subject class. So we apply integrated method into 5th grade elementary students. At first teaching schedule is constructed on Korean, Social, Science, Ethics, and Art classes, and then movie materials are applied. Finally we let students write study book. Study book says that students take great interest and can promote the thought ability.

The main purpose of this study is to reveal the educational value of the Chinese drama and present a concrete and feasible Chinese speaking teaching-learning programme targeted at intermediate level Chinese learners through storytelling and role-play. There is some advice for Chinese speaking teaching-learning by using Chinese dramas. Firstly, applying various techniques actively such as storytelling and role play, not only could it help to correct Chinese speaking pronunciation, but it could also help students to make up and express their ideas as free as possible. Secondly, it's necessary to accord with the teaching objectives of Chinese speaking, students' actual level and requirements to select Chinese dramas as Chinese speaking teaching-learning materials. Thirdly, it's noteworthy that teachers should select Chinese dramas with various genres or theme according to social development to promote the fun of class and maximize the educational value of Chinese dramas as teaching-learning materials.

As the existing edutainment contents for children are mostly comprised of educational tools which unilaterally induce educatees to passively respond to them, the content-creating methodologies in terms of which active and voluntary learning is made possible is urgently needed. In this paper, we present the implementation of the tangible 'electronic dice' interface as an interactive tool for behavior-based edutainment contents, and propose a methodology for developing edutainment contents for children by utilizing the recognition technique of hand movement based on depth-image information. Also proposed in the paper are an authoring and management tool of learning quizzes that allows educators to set up and manage their learning courseware, and a log analysis system of learning achievement for real-time monitoring of educational progress. The behavior-based tangible interface and edutainment contents that we propose provide the easy-to-operate interaction with a real object, which augments educatees' interest in learning, thus leading to their active and voluntary attitude toward learning. Furthermore, The authoring and management tool and log analysis system allow us to construct learning programs by children's achievement level and to monitor in real-time the learning development of children educatees by understanding the situation and behavior of their learning development from the analytic results obtained by observing the processes of educatees' solving problems for themselves, and utilizing them for evaluation materials for lesson plans.

Lentinus edodes powder was added at 1-3%(w/w) to improve functional properties of jocheong. Content of crude protein, ash, crude lipids, total mineral, free sugar and reducing sugar increased with increasing amount of L. edodes powder, while viscosity and solid and carbohydrate contents decreased. Through amino acid analysis, 17 amino acids were identified and quantified, glutamic acid being the major amino acid. No significant differences were observed in fatty acid composition and pH between control and L. edodes powder-added jocheong. Addition of mushroom powder in jocheong decreased lightness, yellowness and redness in Hunter's color value. Sensor score of jucheong containing 1% of L. edodes powder was similar to that of control. Results showed jocheong containing less than 2% L. edodes powder gave highest scores in quality characteristics and sensory evaluation.
