The purpose of this project is to create small parks in elementary schools in order to improve the educational environment and also to increase the amount of greenspace in the city. Above all, the main goal is to create space for local residents in which they can enjoy their leisure time. During a basic investigation and document investigation of elementary schools in Daegu, I placed the priority on choosing the schools that showed the most promise. Also, by doing a survey about the present conditions at schools, I verified, compared, and analyzed the validity of creating small parks in elementary schools. The summary of the results are as follows. The average area available for building small parte in Daegu elementary schools is $7,447m^2$. Even though this area is not as large as a neighborhood parti the difference is not that great. Therefore, I assumed that building small parks in schools would be as effective as building neighborhood parks. The standard size for a children's parks is $1,500m^2$, and if small parks were to be constructed in all school areas with available space larger than a children's park (i.e., larger than $1,500m^2$), the amount of added park greenspace would equal $1,217,953m^2$. The number of schools with areas under $1,500m^2$ is only 3% of all schools in which small parte can be created(5 schools). Schools that have between $1,500m^2$ and $8,000m^2$of greenspace make up 59.7% of all schools in which small parte can be created (98 schools). Schools that have greenspace of more than $8,000m^2$ make up 37% of all school in which small parks can be created (61 schools). The standard area for neighborhood parte is $10,000m^2$ (building-to-land ratio 20%). Schools that have areas that are larger than the standard area for neighborhood parte make up 31% of all elementary schools in Daegu (61 schools). Therefore city greenspace would increase to a total of $694,805m^2$ by making use of these schools, which would represent 7% of the park greenspace in Daegu.

The purposes of this study were to investigate concepts of Korean and American elementary school pre-service teachers on combustion, and to compare the concepts of Korean pre-service teachers with those of American pre-service teachers. For this study, concept test on combustion was administered to 23 Korean and 18 American elementary school pre-service teachers. The test composed of 6 items: 'Definition of combustion', 'The reason why a candle in a glass bottle is blown out when the bottle was closed', 'The change of gases in the bottle when a candle burns in it', 'The combustion products of a candle', 'The combustion products of steel wool', and 'The combustion products of a substance'. The results showed that the rates of elementary school pre-service teachers who had scientific concepts on combustion were very low in both Korean and American pre-service teachers' groups, although they were a little different from items. However the rates of pre-service teachers who had partial concepts and misconceptions on combustion were high in two groups. The levels of Korean elementary school pre-service teachers' concepts were a little higher than those of American elementary school pre-service teachers' concepts. The contents and activities on combustion which are in Korean and American science textbooks seem to affect building up their concepts on combustion.

The number of students choosing science, technology, engineering, and mathematics (STEM) related careers are declining. Thus it became a worldwide challenge in the $21^{st}$ century. As public images of the engineers are unfavorable and inaccurate, misconceptions and stereotypes about engineers are prevailing. The purpose of this study was to investigate elementary school students' perceived mental and pictorial images of engineers and the nature of engineering work. This study involved 512 fifth and sixth grade students (Boys: 287 and Girls: 225) from four elementary schools at one of metropolitans in South Korea. The Draw An Engineer-Korean version (DAE-K) was developed based on Draw an Engineer (DAE) and Draw a Scientist (DAS), and Song and Kim (1999)'s instruments. A pilot-tested was conducted with 33 elementary students prior to the main study. The students were asked to answer how they think the engineers would be, to draw an engineer at work, and to write the engineer's personal information and the job description. Engineers were perceived as a person fixing, building, manufacturing, working outdoors in labors' clothes such as a robe. Engineers were shown with building tools, robots, airplanes, machines, conveyor belt, etc. Moreover, compared to the scientists, engineers were perceived as less intelligent, less imaginative, and less accurate. The results of this study revealed that elementary school students had a lack of accurate images of engineers. Students' current perceived images of engineers could help educators find the baselines for the future engineering education in elementary schools. In addition, the findings of this study could also contribute to the development of engineering education in terms of gender issues, STEM career choice, and even cultural diversity.

In this paper the problem of calculating the probability that the responses of a wind-excited structure exceed specified thresholds within a given time interval is considered. The failure domain of the problem can be expressed as a union of elementary failure domains whose boundaries are of quadratic form. The Domain Decomposition Method (DDM) is employed, after being appropriately extended, to solve this problem. The probability estimate of the overall failure domain is given by the sum of the probabilities of the elementary failure domains multiplied by a reduction factor accounting for the overlapping degree of the different elementary failure domains. The DDM is extended with the help of Line Sampling (LS), from its original presentation where the boundary of the elementary failure domains are of linear form, to the current case involving quadratic elementary failure domains. An example involving an along-wind excited steel building shows the accuracy and efficiency of the proposed methodology as compared with that obtained using standard Monte Carlo simulations (MCS).

The purpose of this study is providing a systematic method of exterior, interior finish materials and color scheme for elementary school and the actual color plans of elementary schools in Busan was analyzed to support the study. As a powerful design tool, a finish materials and a color are very effective to alter the perception of a building and a view. Most of the school, a shape and a material of elevations are monotonous and uniform and it makes students are hard to attach to their schools. As a place for learning and school life, the inner space of elementary classroom needs to be considered very important. The new basic guideline for developing and planning of architectural design could be achieved by researching a current plan and a finish material in elementary school. As a result, this study will benefit in planning both the exterior and interior environments of color.

The purpose of this study is to suggest improvement plans of School Green Building Certification System by comparing items of domestic system with those of foreign system. Especially, we focused on school use classification. Use classification of Green Building Certification System must be based on Building Codes and reflect the nature of building use and size. Schools are divided into three groups ; preschool, school(elementary, junior high school, high school), university and ect. Also they must be set up assessment method reflecting the nature of school use and size.

The purpose of this study was to acquire a better of how creativity center is perceived among students, teachers and parents by administering a questionnaire. A total of 320 people participated in this survey. We developed the questionnaire which as categorized by four specific areas: 1) people's overall perceptions of creativity education; 2) the way of using the creativity center 3) programing of creativity center 4) space composition of the creativity center. The summary of survey results included; firstly, people had paid attention to creativity education and creativity education; secondly, they want to make use of creativity center with informal learning and extra-curriculum; thirdly, they prefer to participate in many experience activities such as camp or experiments; lastly, they more need creativity experience program and utilization of DIY education. In conclusion, students, teachers and parents recognized creativity center is needed. Therefore, more intensive research and follow-up study on building creativity center should be highly considered.
