        초등교육전공 대학원 설치의 필요성에 관한 제언

        권석주 한국초등교육학회 1990 초등교육연구 Vol.4 No.1

        I urge and propose the primary education Gradunte Schools to be instituted. 1. To secure technical man power which is essentially needed for development and application of educational methods through which we can efficiently propel the 21C-directing primary education end of hewthy, independent, creative and moral character building. 2. To secure indispensable technical man power for altive on-the job training. 3. To enlarge the chance of systematic in-service teachers' training which is well connected with pre-service training. 4. Institution of the primary education Graduate Schools at each education college is urgently required to enhance the technicality of the whole primary teachers. 5. The Graduate School Shall be on the Class session system : Day time class for graduates from education colleges and other universities ; Evening or summer class for in-service teachers. 6. Majoring courses shall be classified as follows : Pedagogy Field such as primary educational administration, primary education curriculum, primary education method, primary extra curriculum activity, child psychology and guidance, educational engineering and other 13 primary school subjects : Special Field such as early child education, social education and special education. 7. The School system shall be on 4 one year-long terms with four-step credit from the point of view of the lifelong education. Students through with each course, that is, fundamental course (1st term), developmental course (2nd term), intensive course(3rd term) and fixation course(4th term) shall be given one step-salary raise each. The salary raise and the M. A. degree at the same time. Shall be received by the students who will complete all the courses, so that we can expect pay improved and in-service teacher training systematized through entering upon studies.

        벼 수확 후 수분함량별 건조지연에 따른 쌀 품위 및 화학성

        권석주,송은주,권영립,최동칠,최영근,권태오 韓國作物學會 2006 Korean journal of crop science Vol.51 No.1S

        쌀 품질의 고급화를 위한 벼 수확 후 관리기술체계를 확립하기 위하여 벼 수확을 대형포대 및 콤바인포대로 수확한 후 수분함량 별 야적기간 연장에 따른 쌀 품위 및 품질변화에 미치는 영향을 조사였다. 수확당일 수확시간에 따른 정조의 수분함량은 23.7~28.8% 로 수확시간이 늦어질수록 낮았고, 수확 후 건조지연에 따른 정조의 외관변화는 저장포대가 대형인 경우 3일째 정조의 색깔이 변하고 악취가 심하게 발생하였으며 콤바인포대는 4일째부터 색깔이 변하고 악취가 발생하였다. 포대내부의 온도변화는 대형포대는 저장기간이 길어질수록 그리고 수분함량이 높을수록 증가되는 폭이 컸으나 콤바인포대는 수확당시 수분함량에 따라 일정한 비율로 증가되는 경향이었다. 대형포대에 저장된 정조의 수분함량은 저장 2일째부터 증가되었고 수분함량이 높을수록 증가폭이 컸으나 콤바인포대의 경우는 수확 시 수분함량이 적은 경우 약간 감소하는 경향이고 높은 경우는 약간 증가되는 경향이었다. 수확 후 건조가 지연될수록 단백질, 아밀로스함량은 차이가 없으나 지방산은 증가되었고 대형포대가 콤바인포대에 저장된 정조보다 지방산 증가폭이 컸으며 수확 후 건조지연일수나 벼 수확 시 수분함량이 높을수록 현미의 완전미율은 감소되고 청미와 피해립율이 증가되었으며 백미품위 역시 비슷한 경향이었다. 따라서 미질저하를 최소화 할 수 있는 포대종류별 건조지연 한계기는 대형포대가 벼 수확 후 1~2 일 이내, 콤바인포대는 2~3 일 이내로 추정되었다. This study was conducted to establish the post-harvest management system in rice. Harvested hulled rice was gathered into large-scale bag and combine bag, in which the rice quality and the influence on quality change were investigated on various storage periods and moisture contents. Moisture content of hulled rice ranged from 23.7% to 28.8% on different harvest times, which grew lower as harvesting time was delayed. When desiccation was retarded hulled rice in large scale bag was changed in color and emitted an of offensive odor in 3 days and that in combine bag showed similar symptom in 4 days. Inner temperature in large scale bag was changed a lot when the storage period was prolonged and also the moisture content was higher while that in combine bag increased regularly corresponding to the moisture content at the time of harvest. Moisture content of hulled rice stored in large-scale bag increased 2 days after harvest and the more moisture content showed the more increased tendency, while in the case of combine bag the moisture content was not changed much whether the hulled rice contained low or high moisture content in harvesting. As desiccation was delayed fatty acid increased much more in large-scale bag than in combine bag even though protein and amylose contentwere not changed. As desiccation was delayed more and hulled rice contained moisture more in harvesting head rice ratio of brown rice decreased and green-kerneled rice and damaged grain ratio increased and quality of milled rice also became deteriorated. As a result, desiccation day to minimize the deterioration of rice quality was estimated 1-2 days in large scale bag and 2-3 days in combine bag after harvesting.
