The purpose of this study was to provide basic data for inquiring effective use of school garden by researching the recognition and practical management on school garden of elementary school teachers. The teachers recognized that school garden was contributing to students' emotional cultivation, cultural learning and feeling on importance of life. The more teaching career recognized that school garden was a great help to students on learning attitude. The teachers recognized that the garden structure and plants, planting design were in harmony. Teachers have more than 31 teaching years recognized that they knew kinds of plants in school garden well. The more teaching career were more interest in practical classes in school garden. When panting trees or flowers in a school garden, teachers thought their opinions were considered well. Especially female teachers in thirties and having teaching career between 11 years and 20 years recognized that acceptance degree of their opinions was very high. Most of teachers recognized that they knew considerably the name of plants in school garden, especially female teacher and the lower career teacher were so.

Microprocessor를 利用한 直流電動機의 速度制御

金玉中,李興浩 충남대학교 공업교육연구소 1983 論文集 Vol.6 No.2(B)

This paper is concerned with the seperately excited dc motor speed control using a microprocessor. The voltage, necessary for dc motor drive, is adjusted by a chopper and its control circuits are fired with digital circuits. Therefore, no D/A converter is needed between power circuits and a microprocessor. A voltage that relates to the motor speed, is measured through a tachogenerator. The analog voltage, measured through a tachogenerator, is converted into the digital signal by the A/D converter and the converted digital signal goes into the microprocessor. For the purpose of maintaining tho motor speed constant, the digital signal is compared with a reference setting, and the error is used to adjust the on-off time of the chopper. Throughout the experiments, we recognized that the dc motor reaches at the desired speed rapidly and maintains the reference speed in spite of a variable load.

배추를 다듬기 하는데 발생한 폐기량은 7.5∼14% (w/w)이었고 10±2℃에서 30일간 방치한 경우 약 17∼25% 발생하였다. 간절임 배추의 pH값은 저장온도가 낮을수록, 염도가 높을수록 높았으나 calcium chloride 첨가가 절임배추의 pH값의 변화에는 영향을 주지 않았다. 유리당의 함량변화는 최소 약 4% 수준에서 산의 함량과는 반비례적으로 변화하여 저장 90일에는 소금농도가 낮고 저장온도가 높은 경우 적게 감소되었다. 균수변화에서 세균과 효모는 전 기간을 통해 증가한 반면, 곰팡이는 감소하였다. 한편 산의 첨가와 CaCl? 첨가시 소금으로만 절인 경우보다 세균과 효모는 낮은 속도로 증가했다. 저장중 경도는 온도가 낮고 염도가 높으며 젖산을 첨가한 경우 다소 높게 유지됐고, CaCl? 첨가의 경우 잎과 줄기에서 월등히 높았다. 휘발산과 불휘발산의 함량변화에서 온도가 낮고 염도가 높은경우 불휘발산의 함량이 낮았는데 특히 젖산 첨가시 불휘발산의 증가를 억제하는 것으로 나타났다. flavor score 는 저온과 고염도 젖산첨가시 유리하였다. This study was to investigate the effects of storage temperature, lactic acid and calcium chloride addition about the pH values, sugar content, firmness, volatile and nonvolatile acidity, microbial counts and flavor of the salted chinese cabbages during storage (90 days), and trim loss of chinese cabbages during the trimming of raw and storaged (30 days) chinese cabbages. The waste rate was in the course of trimming of raw chinese, cabbages was 7.5-14(w/w). The proportion of trim loss was highly correlated to sunshine duration, temperature, humidity and handling for the storage. Free sugar was decreased fast and much in the case of high temperature and low level sodium chloride in comp rison of low temperature and high sodium chloride, but ?? and lactic acid did not affect its changes. Time to reach the lowest pH values were fast in the case of high temperature and low salt content. Lactic acid affected inital pH value (4.38-4.57) and constant pH value in each case was increased at low salt content, at high temperature, and then the pH values were slowly increased when volatile acidity was increased. Firmness was high in the case of addition of lactic acid and calcium chloride, low temperature, high sodium chloride concentration. Especially, calcium chloride addition remarkably showed high firmness. Flavor score was high in the case of low storage temperature, high yeast counts were slowly increased in spite of low temperature and high salt content, but mold counts were slightly increased during all period Lactic acid, low temperature and high sodium chloride were effective to inhibit the growth of microorganisms. Volatile and nonvolatile acidity was increased during all storage period ; however, lactic acid and low temperature storage inhibited their increase. To conclude, quality of salted chinese cabbages was effective at low temperature storage, lactic acid and calcium chloride addition, and high salt concentration.

Our unicycle has simple mechanical structure.But unicycle's dynamical system is a very sensitive unstable nonlinear system. equations of motion for a simple unicycle robot were derived using Lagrage's method. In this paper, a human fuzzy influence control mechanism was established throught an inquiry into human riding a unicycle, and we developed a hybrid controller to control our unicycle robot. This proposed hybrid controller is consisted with a pure PD and two fuzzy gain scheduled controllers and a direct fuzzy logic controller. Computer simulation results show that our hybrid controller has robust control performnance to unstable nnonlinear unicycle robot system.

최중옥,김주창 한국특수아동학회 2002 특수아동교육연구 Vol.4 No.2

본 연구는 원예ㆍ압화 프로그램이 ADHD 아동의 주의력 결핍 행동의 향상에 미치는 효과를 규명해 보기 위한 프로그램 구성과 실험설계를 연구하는데 그 목적을 두고 있다. 본 연구의 대상은 일반학급에 재학중인 아동 가운데 DSM-Ⅳ의 주의력 결핍 과잉행동 장애 진단준거, ADHD-SC-4(ADHD Symptom Checklist-4) 범주 A 항목 검사결과 주의력 결핍증후군 심각도 점수(Symptom Severity Scores)에서 주의력 T≥59, 중도이상의 심각도 점수를 나타내는 아동 3명을 대상으로 선정한다. 실험설계는 ABAB 연구설계를 적용한 20회기의 원예ㆍ압화 프로그램을 실시하는 가운데 석 달반동안 관찰될 것이다. 그리고 관측행동 자료는 ADHD 아동의 주의력 결핍행동의 주요 특성인 선택적 주의력의 결핍, 지속적 주의력의 결핍, 주의력 조절능력의 결핍 등을 중심으로 통계적으로 뿐아니라 임상적으로 분석될 것이다. 본 연구는 교육현장에서 학생들의 주요한 기초학습기능인 주의력의 향상을 위하여 원예 및 압화활동을 활용한 프로그램을 제시한 것으로 현장교사나 부모들의 특수교육 프로그램 개발이나 실행에 시사점을 줄 것으로 본다. The purpose of this study is to examine the effect of the Horticulture & Pressed flower Program on the improvement of attention deficit behavior of ADHD children. The subjects of this study are the children in general education classes whose Symptom Severity Scores are T≥59, that is higher than average, based on the result from the test of DSM-IV, ADHD-Symptom Checklist 4, Item A, which is a diagnosis standard of attention deficit behavior. Among the 2nd grade students in Elementary School A in Busan, 3 children of ADHD will be observed for three and half months, with 20 times of the Horticulture & Pressed flower Program applied under ABAB design. And the data of observed behavior will be analyzed statistically and clinically on the point of three major characteristics of ADHD children's attention deficit behavior, which are the lacking of selective attention, the lacking of constant attention, and the lacking of attention adjustment ability. The recommendation for further study is as follows; First, A study on the influencing on change of ADHD by developing Horticulture & Pressed flower Program. Second, Not only ABAB research design, but also other research design will be needed to study Horticulture & Pressed flower Program for ADHD. Third, A study on the Horticulture Therapy Program for handicapped family.

Mechanical properties of compomers would be obtained mainly by photopolymerization by visible light irradiation. Photopolymerization behavior of two commercial compomers was investigated by FT-IR spectral analysis and differential photocalorimetry(DPC). The results obtained were as follows: 1. From FT-IR analysis, it was found that the compomer products were photocured mainly by radical polymerizations of multifunctional methacrylate monomers. Final conversion values of the polymerizations after exposure to visible light for 60 sec were 67% for Dyract and 59% for Compoglass. 2. Upon exposure the compomers exhibited autoacceleration and autodeceleration, which are usually observed in bulk polymerizations of multifunctional monomers. 3. Dyract showed higher rate of polymerization and conversion of double bond than Compoglass.
