The education effect of environmental impact cognitive instruction on high school students was investigated. Environmental values of students could be classified into egocentric, social-altruistic and biospheric values like those of Schultz’s three kinds of categories. The value distribution of students consists 44.7% of egocentric and biospheric value groups and 12.5% of social-altruistic value group, respectively. The environmental function such as knowledge and skill did not show remarkable differences between value groups. The environmental value only affected the attitude function. The biospheric value group had the higher attitude function than other value groups. The environmental impact cognitive instruction enhanced the environmental functions irrespective of the value group or instruction type. However, significant variables were different according to environmental functions. Environmental functions such as knowledge and skill were influenced by the instruction itself. The attitude function was dependent on instruction itself, value type and instruction type. The optimum application of the environmental impact cognitive instruction can be efficiently achieved through class division into egocentric value group and biospheric value group. Alternatively, the proper combination of instruction methods focused biospheric and egocentric impacts in a class can be recommended.

본 논문에서는 특수 고적의 소형 전자계산기를 단일 뻐스선 방법에 의한 TTL 집적회로로 설계하였으며, 각 지령어의 길이를 16비트르 구성함으로써 더욱 간편한 콤파일러를 연구하였다. 또한 본 실험에서 160nsec의 기본 주기를 택함으로써, TTL IC의 동작시간에 따른 최적치와 기억소자의 악세스 타임이 같게 되었고, 구성 회로도 간단하게 만들어졌으며, 모두 프로그램도 만족하게 처리되었다.
