The purpose of this study was to develop an educational app that informs parents of elementary students with correct information on pesticide residue based on their awareness and information needs on pesticide residue. A survey was conducted from 918 parents living in 8 different districts of Korea. The results of the survey indicated that a majority of parents felt uncomfortable with pesticide residue and wanted to have the proper information regarding it. Based on the above results, an app named 'Perfect Conquest of Pesticide Residue' consisting of 5 main menus of 'Pesticide residue, Is it safe?', 'Safe management of pesticide residue', 'Perfect removal of pesticide residue on fruits and vegetables through washing', 'Shopping without anxiety', 'Playground' and their own sub-menus was developed. When the app was applied to 30 parents using smart phones, a majority of them were satisfied with the contents of detailed information and fun activities. Therefore, this app could be utilized as an effective educational tool for the parents of elementary students by allowing them to have proper awareness on pesticide residue. Furthermore, more apps could be developed on other food risk factors to promote safe dietary life.

This study compared evacuation effectiveness between the conventional school floor plan and a suggested hypothetical floor plan that was generated by a mathematical model that is commonly applied in the field of industrial engineering. Recent school buildings became much more complicated in floor planning due to the new educational system and modern curriculum than the old days. Nevertheless, architect's approach to floor composition in terms of fire emergency evacuation planning, still has no relation to optimized effective but relies more on a conventional school planning. Therefore, since elementary school buildings are much more likely to be exposed to any fire related events than middle school or high-school, emergency exit effectiveness based on spatial composition has to be seriously evaluated with a scientific method. The algorithm, which acquires the number of persons in each spatial type (node) per floor and the minimum physical distance between spatial types (arc), can propose the most optimized spatial compositing per floor regarding emergency evacuation event. Consequently, this study evaluated elementary school's fire exit effectiveness with the scientific tool and suggested the most reliable spatial composition per floor regarding possibile emergency evacuation event.

This study analyzes and compares the contents of the prohibited history textbooks to the officiated curriculum textbooks during the Japanese Intervention period. By doing so the study will discuss the curriculum regulation through the new educational sociology aspects. The results are as follows. First, the Residency-General placed Japanese advisors in educational faculties to prepare a foundation for colonial education. It was intended to influence the educational system and its contents by displaying their superiority represented by their group of elites. Second, In 1908, the authorities issued the textbook regulation, which controlled the contents of the education before the book was published. The standard for the regulation was to exclude contents that are disadvantageous to Japan, and is favorable to colonial rules. Third, The prohibited textbooks contained contents that violate the standards. This shows that during the Residency -General period the textbook examination system was a tool to control school curriculum. Fourth, after comparing the contents of both prohibited textbooks and regulated textbooks, the prohibited history textbooks included the national independence, the victory over the Japanese, patriotism, and unfavorable relations with Japan. On the other hand, the regulated textbooks omitted patriotism and ethnicity-independent content, and instead filled its content with a friendly relationship Korea had with Japan at the time. This phenomenon proves that knowledge and the way of thinking are favorable towards superior groups of society and have an influence in determining the content of school education. This is the new education sociology theology.
