In school safety education, it was difficult to apply how to link the safety education according to grades year, and student’s interest was reduced due to the repetition of existing safety education contents and the absence of new teaching methods and tools. In this study, as a new type of safety education, a performance forms fire safety education program was developed. This program aims to increase students’ interest and satisfaction in safety education, and to this end, it was connect with korean elementary science curriculum and combined various engineering teaching materials or tools and methods. Developed program was applied to 2,231 students, 25 schools in 10 regions of Gyeonggi-do and surveyed 476 fifth and sixth grade students program satisfaction and 3 factors of interest in fire safety education who could respond to the survey. As a result of applying the program, more than 90% of students responded more than 'satisfied' in all areas. and statistical test(independent t-test and non-parametric test) indicates over-all satisfaction and interest factors in the program are high regardless of gender and grade, so the effectiveness can be guessed indirectly and there is a universal applicability also. Moreover, examining the influence of student interest level in the satisfaction of the fire safety program, it was found that in order to increase the satisfaction of fire safety education, students should have more fun with the content and feel interest in the teacher's teaching method or explanation.

2001년 국립식량과학원 인공기상실에서 수경재배로 규산의 시용 여부가 영양생장기 벼의 수분과 질소흡수량에 미치는 효과를 조사하여 규산시용 여부 및 공급된 질소의 형태별 처리에 의한 시험품종들의 수분과 질소이용효율을 산출한 결과는 다음과 같다.1. 처리 67일 후의 벼 건물중은 규산처리 시험구 및NH4+NO3 혼합시용 처리구가 규산을 처리하지 않은시험구 및 NH4 단독시용 처리구보다 유의하게 증가하였음.2. 이앙 후 67일간 조사된 벼의 수분흡수량은 규산처리와 규산 무처리 간의 차이가 없었으나 질소흡수량은규산 무처리에 비해 규산처리구에서 유의하게 증가하였음.3. 질소형태별로는 NH4 단독 시용보다 NH4+NO3 혼합시용에서 규산처리 여부와 관계없이 수분과 질소흡수량이 월등히 많았음.4. 수분이용효율은 규산처리 시험구가 규산을 처리하지않은 시험구에 비해 유의하게 증가하였으나 질소형태별 처리에서는 차이가 없었음.5. 질소형태의 혼합처리가 암모늄태 단독처리보다 질소흡수량은 유의하게 많았으나 질소이용효율은 감소하였음.
