Today, the gobal community is confront serious environmental crisis derived from related problems energy and resources. To deal this crisis, people must take action in order to preserve current environment with ecological understanding of the relationship between human and environment. The principle of this thesis is to observe public endeavor toward environmental education program, environmental perception and environmental preservation behavior, and the influential factors to those conducts. First of all, we will look into the perception toward environmental deterioration, environmental perception, environmental preservation behavior which thought to be a ground solution to lesson the problems, and then the environmental education program. In accordance with those research, it will be presented the feasible directions of environmental education program for general public. This research consists of 10 topics. The topics are the interests of public about environmental problem, perceived pollution level, general knowledge about environment, perception related to environmental problem, opinions about the environmental education program, attitude towards environmental organization, suggestions for future environmental education program, and campaign for environmental preservation. Through the research, we have reached some analytical conclusions are followed: First, the level of public concerns about environmental problems is high regardless its age and sex, and the level has been growing compared to the past one. The result also shows that people in urban and industrial areas feel much more seriously pollution problems than those in rural and coastal areas. In addition, according to the survey result, household and industrial sewage are regarded as the primary causes for water pollution. Secondly, the results show general public's understanding on environment have been universalized and thus the level of common knowledge on global environment has been increased, as environmental problems have been raised by newspapers and mass medias and various movements have been accomplished by environmental protection organizations. Thirdly, although the necessity of environmental education was emphasized the purpose of environmental education was unclearly appeared. Furthermore, actual participation to the environmental education program and taking courses by joining environmental organizations were rarely shown. Although some cases have the experience of taking education courses, the negative reactions came out in the opinion of education content and methodologies. Fourthly, the analysis on curriculum of future environmental education show various opinions. The attentions have drawn on the dealings of waste industrial and chemical waste which will cause environmental problem artificially, as well as on global environment, or natural environment such as resources, land, water, atmosphere. The results show many people recognized administration extent such as environmental policy, law and ethics as environmental categories. This implies the curriculum of those areas have not been properly founded and further researches should be followed. From above results, environmental problems should not be regarded as simple problems and it should bring out new recognition for general public in everyday life. In addition, environmental education courses, with practical environmental preservation should be developed and programs and organization which will utilize those educational materials should be more activated.

최효임(Choi Hyo-Im),김성일(Kim Sung-Il) 한국청소년정책연구원 2004 한국청소년연구 Vol.- No.39,40

본 연구에서는 초기 청소년에 해당되는 초등학교 5학년생 445명을 대상으로 설문조사를 실시하여 부모의 양육태도와 학교생활 적응의 관계를 분석하였다. 부모의 양육태도 가운데 자율-통제적 태도에서는 여학생이 남학생에 비해 부모 모두가 자율을 더 허용한다고 지각하였고, 부모의 학력이 높을수록 수용적인 태도를 보였다. 성취 압력에서는 남학생이 여학생에 비해서 부모가 과잉 기대를 하는 것으로 지각하였고, 40대인 아버지가 30대보다 자녀에 대한 성취 압력이 높게 지각되었다. 초기 청소년의 학교생활 적응은 대체적으로 성별에 따라 차이가 없었으나 이 중 교사와의 관계에서 여학생이 남학생에 비하여 더 잘 적응하는것으로 나타났다. 부모의 학력에 따른 자녀의 학교생활 적응은 아버지의 학력이 높을수록 자녀의 교우 관계가 원만하고 학교 수업에 더 잘 적응하는 것으로 나타났다. 부모의 양육태도에 따른 자녀의 학교생활 적응의 차이에서는 부모 모두 또는 어느 한 사람이라도 자녀를 수용하고 자율적인 태도로 양육하였을 때 아동이 학교생활에 전반적으로 더 잘 적응하는 것으로 나타났으나 부모의 성취 압력은 자녀의 학교생활 적응에 영향을 미치지 못하는것으로 나타났다. 마지막으로, 청소년의 학교생활 적응에 가장 큰 영향을 미치는 요인은 아버지의 수용적 태도로 나타났다. This study was to investigate relations of parental child-rearing behavior and the fifth graders' school adjustment. Four hundred and forty five early adolescents were drawn from three elementary schools in Kangnung. Girls perceived parental child-rearing behavior as more autonomous than boys did, while boys perceived it as more achievement-oriented than girls did. Girls also associated better with teachers than boys did. Parents with higher educational level showed more affectionate than those with lower one. And fathers in the age of 40s showed more achievement-oriented than those of 30s. Students who had fathers with higher educational level showed to adjust better to school learning and to associate with better with friends than those with lower educational level. In general, students whose parents were affectionate and autonomous tended to adjust better to school environment. Father's acceptance was selected as the most useful variable in estimating school adjustment for early adolescents.

본 연구는 식물공장에서 청경채와 상추의 발아조건과 육묘배지 및 육묘 시 양액농도가 묘의 생육에 미치는 영향을 구명하고자 수행되었다. 청경채와 상추의 발아율은 광의 유무와 온도처리(15, 20, 25℃) 간에 유의적 차이가 없었으나, 육묘배지 간에는 우레탄스펀지의 경우 파종 전ㆍ후 수분관리 유ㆍ무에 따라 큰 차이를 보였다. 즉, 우레탄스펀지 배지에서 파종전ㆍ후 수분관리를 하지 않았을 경우 암면에 비해 발아율이 현저히 낮았으나, 수분관리를 해주었을 때에는 암면보다 발아율이 높았으며, 묘의 생육도 암면과 차이가 없었다. 그리고 청경채의 생체중은 EC 1.0dSㆍm?¹에서 1.5dSㆍm?¹에서보다 1.8배 무거웠고, 0.5dSㆍm?¹에서보다는 6배 무거웠다. 상추의 생체중 또한 EC 1.0dSㆍm?¹이 1.5dSㆍm?¹와 0.5dSㆍm?¹에 비해 1.7배와 3.5배 각각 무거웠다. This experiment was conducted to study the effects of germination condition, nursery media and nutrient concentration in plant factory on the growth characteristics of pak-choi and lettuce seedlings. The results showed that temperature (15, 20, 25℃) and light conditions (lighting and no lighting) had no significant effect on germination rate of pak-choi and lettuce, whereas the interaction of growing media (rockwool and urethane sponge) and moisture management before and after sowing had significant effect on germination percentage. In case of no moisture management before and after sowing, germination percentage was much higher in rockwool medium than urethane sponge medium. But germination percentage of urethane sponge was higher than that of rockwool with applying moisture before and after sowing. At the nutrient concentration of EC 1.0 dSㆍm?¹ the fresh weight of pak-choi was heavier than in EC 1.5 and 0.5 dSㆍm?¹ by 1.8 and 6.0 times, respectively. At the nutrient concentration of EC 1.0 dSㆍm?¹ the fresh weight of lettuce was also heavier than in EC 1.5 and 0.5 dSㆍm?¹ by 1.7 and 3.5 times, respectively.

온라인 동조 PI 제어기법을 이용한 영구자석형 동기전동기의 속도제어기 설계

林相德,朴勝燁,全寅孝,崔重暻 창원대학교 공작기계기술연구센터 1999 연구업적집 Vol.1 No.1

본 논문은 브러시리스 직류 전동기의 속도제어를 위해 파라메타의 추정 없이 입력과 출력의 패턴을 관찰하여 PI 이득을 온라인(On-line)으로 설정하는 방법을 제안한다. 비례이득은 한계입력을 인가하여 가장 빠른 속도 상승을 유도하는 과정에서 설정되고, 적분이득은 비례제어 과정 중에 오버슈트 방지와 안정된 수렴이 적적히 이루어지도록 설정된다. 따라서 제안된 PI이득 조정은 온라인으로 제어와 동시에 수행됨으로써 시스템 파라메타 추정 등의 부가적인 작업이 필요 없다. 본 논문에서 제안하는 PI이득 조절기법은 직류전동기의 속도제어에 있어서 빠른 응답과 오버슈트 문제를 동시에 해결할 수 있고, 기존의 Auto-tuning 방법보다 간편하고 실용적이다. 컴퓨터 시뮬레이션과 실제 실험을 통하여 제안하는 방법의 유용성과 안정성을 보인다. In this paper, a method of on-line PI gain-tuning is proposed for the speed control of brushless D.C. motor by investigating the pattern of input and output without estimating parameter. Proportional gain is tuned in the process to obtain a fast speed response by supplying the maximum constant input And integral gain is appropriately tuned in the process of proportional control so that the response may be stably converged and the overshoot may be prevented. Therefore because both control and gain-tuning are executed concurrently, additional works that estimate parameters and so on aren't required in the proposed method. In the proposed method, both fast-response and overshoot problem are well solved, and it is mire useful and convenient than existing auto-tuning methods in the speed control of D.C motor. It is illustrated by simulations and experimental results that the proposed method is useful and stable.
