Objectives: This study was conducted to examine the effects of nutrition education with a dietary guidebook for children on dietary attitude, nutrition knowledge and nutrient intakes. Methods: The subjects were 54 higher grade elementary students (27 educated vs. 27 non-educated). The educated group was provided individual and/or group lessons (40 min/lesson/week, 4 week) using a dietary guidebook of Children developed by The Korean Society of Community Nutrition (KSCN) & Korean Food and Drug Administration (KFDA). The contents were Balanced Diet, Smart Food Choices, Cooking a Healthy Snack and Building a Healthy Body. We examined the differences in nutrition knowledge, dietary attitudes and dietary intake between the educated group and non-educated group. Results: After education, the educated group improved dietary attitude, nutrition knowledge and qualitative nutrient intakes compared to the non-educated group. Specifically, among dietary attitudes, 'taking a meal with salty and spicy food' increased, while among nutrition knowledge, 'functions of protein', 'functions of fat', 'foods with carbohydrates', 'foods with fat', 'foods with vitamins', and 'foods with minerals' were increased. Nutrition adequacy ratio (NAR) scores for vitamin C, iron, and zinc were increased. Conclusions: Nutrition education using a dietary guidebook for children developed by the KSCN & KFDA had positive effects on nutrition knowledge and qualitative nutrient intakes. These findings suggest that nutrition education focused on personalized daily energy and nutrient requirements may improve dietary attitude and quantitative nutrient intakes of children.

Unlike other educational spaces in school facilities, restrooms have remained unpleasant spaces without reflecting the change in social awareness and students' lifestyle. In the process of the 'School Restroom Environment Remodeling Project in Seoul' by means of "user participatory design method", this study aimed to suggest a design of the school restroom environment responding to the different needs of actual users, who are students and school staffs. By surveying them, it was revealed that they have a variety of respective behavioral patterns and spatial needs according to their status, gender, age and working period. Implications of this study are as follows; First, it is necessary to establish a separate restroom facility standards that respond to the characteristics of elementary school students. Second, there should be an expansive approach to widely accommodate with the users' needs that were found out through 'user participation', more than just repairing pre-existing space. Third, it needs to have critical review of the maintenance and operation system itself as well as the improvement of the school restroom environment.

Recently, in rural areas have been occurred closed school due to reduce children of people who consider educational environment. In July 2009 statistic, Closed school are ut to 3,348; sale process(61%), lease(25%), neglect(14%). Closed school are not only local community education, but also to act as cultural and historical role. First of all, it will be utilized public facilities as well as welfare facilities for local residents. In this study suggests the welfare facility where is remodelled as good case so that it will use as a data when closed school need remodeling. The main contents is as follows; it is set the slope next to the school building, a classroom is remodelled 2 triple rooms which are installed Ondol and a toilet, teacher's room is converted into the canteen, corridors are converted into the kitchen. Having good condition in the area, close school is appropriate to use welfare facility and also effective to convert teacher's space into normal space, canteen, kitchen. Finally, developed 2~5 composition type of elderly facility.

This paper analyzed 20 teaching practices of elementary mathematics lessons which were recognized as effective instruction by the local educational offices throughout Korea, using an analytic framework with 4 main domains (i.e., curriculum and content, teaching and learning, classroom environment and atmosphere, and assessment) and a total of 44 sub-elements. The results of this study showed that the lessons focused on the key mathematics concepts according to the national mathematics curriculum and learning objectives, managed students in terms of shared rules within each classroom, and evaluated students' understanding of the concepts at the end of the lesson. However, the lessons did not foster students' calculation skills and only partly used either technology or game. Building on the related studies, this paper included implications of implementing high-quality mathematics instruction.

In this study, the effects of wind fences on the dispersion of the particles emitted from a constructing site located in the building-congested area in Busan, Korea, using geographic information system (GIS) and a computational fluid dynamics (CFD) model. We averaged the wind speeds observed for 10 years at the Busan automated synoptic observing system (ASOS) and we used the averaged wind speed as the wind speed at the reference height (10 m above the ground level). The numerical simulations were performed for 16 inflow directions, before and after the construction of wind fences with the heights of 5 m and 10 m (total 48 simulations). The detailed flows were analyzed for the northeasterly and south-southwesterly cases which predominantly observed at the Busan ASOS. In the northeasterly case, high concentration appeared at the elementary school next to the construction site due to transport by the airflow coming from the northeast. In the 5-m wind fence case, the wind speeds were slightly weaker and the spread of the fugitive dust was slightly less than those in the no wind fence case. In the 10-m wind fence case, the dust concentration at the elementary school has the maximum reduction of 37%. In the south-southwesterly case, the flow pattern became complicated in the construction site due to the terrain and buildings. Fugitive dust was stagnant at the south side of the construction site but rather spread to the north, increasing the concentration at the elementary school. After the wind fence was built, the concentrations inside the construction site became high as the wind speeds decreased inside, but, the concentrations in the elementary school rather decreased.

Everyone knows the importance of environmental education, which is essentially required especially today. In particular, the education could influence greatly students who have to get in their class and they might build their own thought on the basic concept regarding environment and ecosystem through their elementary school period. But the current elementary education has not the independent subject of 'environment' but only refers to other courses some dealing with it, leading to the highly possible failure of achieving comprehensive and concrete approaches toward environmental education. In that sense, it will be meaningful that based on existing academic discussions and approaches about various environmental issues facing our society, we seek desirable directions for environmental education at primary school for sustainable development that is needed in this era and its possible applications. The concept of sustainable development that puts an importance on the harmony between the development of environment and its preservation should be rather the one which helps to satisfy desires of the future and now generation together and also emphasizes that environmental protection should be primarily considered even in the situation in which economic development could be seen necessary. Therefore, the key to environmental education for sustainable development lies in building the attitude respecting 'life and nature' and such value will be accomplished through education.

The purpose of this study is to analyze the types of mathematics journals of elementary school students and to understand how they change in mathematics journals as the grade goes up, and to obtain implications in mathematics education. To this end, 170 of the 222 parish mathematics data submitted to the "Math Journal Contest" were analyzed with the consent of both minors and their parents. As for the framework for analyzing math journal types, 12 types were derived through independent analysis between three researchers. The research results showed that first, the type of math journal written by elementary school students is a variety of journals, such as observation, problem making, concept organization, and review. In addition, as a learning area, it was found that math journal showed a noticeable increase in experimental observation, problem making, and concept journal as the grades progressed, while a small number of idea journal and explanatory journals appeared. However, game (winning) strategy building and types declined. It can be seen that this is evolving from a type that requires activity-oriented or simple descriptions to a type that actively applies mathematical concepts. As such, there are 12-type of math journals, but it is necessary to actively use the teaching materials in writing that can be freely expressed in the school setting.

This paper is estimation of structure damage caused by Explosion in LPG(Liquefied Petroleum Gas) filling station. As we estimate the influence of damage which occur at gas storage tank in filling station. We can utilize the elementary data of safety distance. In this study, the influence of over-pressure caused by VCE(Vapor Cloud Explosion) in filling station was calculated by using the Hopkinson's scaling law and the accident damage was estimated by applying the influence on the adjacent structure into the probit model. As a result of the damage estimation conducted by using the probit model, both the damage possibility of explosion overpressure to structures of max 265 meters away and to glass bursting of 1150 meters away was nearly zero in open space explosion.

The purpose of the study is to propose architectural design standards of the cafeteria planning in educational facilities. In the spatial organization planning, the preferred location of the cafeteria is on the first floor and the types of the floor plan are followed by the forms and space structure of the school building. The area of the cafeteria is related to the size of seating area per person. The direction must sublate northern faced. In interior moving lines for service, the arrange of dining tables has to reflect distance of dining tables or location of pillars. The dining space should better have more than two entrances in terms of occupancy type and convenience. Thus the serving line has to be planed thoughtfully by various factors to avoid confusion caused in serving process. In multipurpose use of the cafeteria, it is feasible when hygiene and management is considered.
