        ‘외국어교육표준’에서의 간 문화적인 이해 - 미국의 한국어표준개발의 경우 -

        유영미 국제한국언어문화학회 2009 한국언어문화학 Vol.6 No.1

        This paper reports on a recent AATK-initiated project to develop National Standards and Guidelines for Korean Language within the framework of the Standards Collaborative of the American Council on Teaching Foreign Languages. When developing high level of language and culture proficiency is considered to be the first priority in the field of foreign language education, it is vital to provide a blueprint to implement a formal sequence of Korean language education for K-16 in the United States. National Standards will prompt constructive development in areas such as teacher education, professional development, curricular design, pedagogical research and connecting heritage language education with formal school curricula. In particular, we will examine how the notion of intercultural understanding is promoted and incorporated within the five big goals (Communication, Cultures, Connections, Comparison, and Communities) of the Standards.

      • 백침계 오이 접목 육묘 시 묘령과 용기 크기가 묘소질, 측치 발생 및 수량에 미치는 영향

        유영미,이상규,김광용,김영철,서태철,이지원,윤형권 한국원예학회 2002 원예과학기술지 Vol.20 No.1

        This study was conducted to examine the effect of seedling age and plug cell size on seedling quality, early lateral vine and yield of the white-spine cucumber. Cucumber cultivar 'Bagseong 3' was sown on Aug. 25 (3-week old seedling after grafting), Sep. 4 (2-week old seedling after grafting), and Sep. 11 (1-week old seedling after grafting), grafted with 'Superunyoung' raised in 50 (78 mL), 32 (200 mL), and 18-cell (350 mL) plug tray filled with peatmoss- based substrate, and transplanted on Sep. 25. The seedling growth increased with seedling age and cell size. Photosynthesis and root activity were the highest in 2-week old seedling after grafting, but not affected by cell size. The growth of 4-week old seedling after transplanting showed the same tendency as seedling growth and the number of lateral vines gave the highest in 3-week old seedling raised in 32-cell plug tray. The number of early marketable fruits and yield of main and lateral vine increased with seedling age and cell size, and was the highest in 3-week old seedling raised in 18-cell plug tray, but there was no difference between 2- and 3-week old seedling. 수출용 백침계 오이 육묘 시 묘령, 용기 크기가 묘소질과 정식 후 초기 수량 및 측지발생에 미치는 영향을 알아보기 위하여 '백성 3호' 품종을 '슈퍼운용' 대목에 접목하여 각각 50구(78mL), 32구(200mL), 18구(350mL) 플러그 용기에서 접목 후 1, 2, 3주 동안 육묘한 후 시설내에서 토양재배하였다. 묘령이 많을수록, 용기 크기가 클수록 묘의 생육량이 많았고, 광합성 속도와 근활력은 접목 2주된 묘에서 가장 높았으며, 용기 크기 간에는 유의성이 인정되지 않았다. 정식 4주 후의 생육도 묘의 생육과 유사한 경향이었는데 총 측지와 장측지 모두 32구 플러그 용기에서 접목 후 3주 동안 육묘한 묘에서 가장 많았다. 초기 과수와 수량은 주지와 측지에서 모두 묘령이 많을수록, 육묘 용기가 클수록 증가하여 18구 플러그 트레이에서 접목 후 3주간 육묘한 묘에서 가장 많았다. 같은 육묘 용기 내에서는 접목 2주 묘와 3주 묘 간에 수량 차이를 보이지 않았다. 따라서 저온기 백침계 오이 재배 시에는 32구 용기를 사용하여 접목 후 2 - 3주간 육묘하는 것이 생육과 경영면에서 유리할 것으로 판단되었다.

        백침계 오이 육묘시 양분결핍이 묘소질, 축지발생 및 수량에 미치는 영향

        유영미,이지원,김광용,김영철,이상규,서태철,윤형권 한국원예학회 2002 Horticulture, Environment, and Biotechnology Vol.43 No.1

        본 시험은 백침계 오이 육묘시 특정양분 결핍 증상과 특정양분 결핍 묘의 정식 후 생육, 측지발생, 수량성 등을 알아보고자 실시하였다. ‘백성 3호’를 ‘슈퍼운용’ 대목에 편엽합접하여 펄라이트 배지로 채운 50구 플러그 트레이에 육묘하여 N-P-K-Ca-Mg=8-2.4-2.4-4.8-1.6me·L-1 원예연 육묘 전용 표준액을 시용한 처리를 대조구로 하고, 각각 P, K, Ca, Mg, Fe, B를 각각 결핍한 배양액을 조성하여 처리하였다. P, K, Ca, Mg 결핍처리에서는 육묘동안 전형적인 결핍증상이 관찰되었으나 Fe, B 결핍처리에서는 외관적인 결핍증상이 나타나지 않았다. 정식 후 초기생육은 육묘시 Ca와 Mg 결핍처리한 묘에서 가장 적었으며 광합성속도와 근활력도 같은 경향이었다. 육묘시에는 외관적 결핍증상이 없었던 B 결핍처리 묘는 정식 8~10일 후 순멎이와 잎의 기형화 증상이 심하게 나타났다. 정식 4주 후의 측지의 엽면적 및 건물중은 대조구, B결핍구, Fe결핍구>Mg결핍구>Ca결핍구> K결핍구>P결핍구 순이었고, 측지수는 B 결핍처리에서 가장 적었으며 초기 수량은 P, K 및 Ca 결핍처리에서 적었다. This study was conducted to examine the effect of nutrient deficiencies on the seedling quality, lateral vine development and yield of white-spin cucumber. Cucumber cultivar Bagseong 3 grafted with Superunyoung was raised in 50-cell plug tray filled with perlite. The nutrient deficient treatments comprised -P, -K, -Ca, -Mg, -Fe and -B in seedling-special nutrient solution of N-P-K-Ca-Mg=8-2.4-2.4-4.8-1.6meL-1. Nutrient solutions were modified to eliminate the specified nutrients without changing the total concentration. During raising seedling, -P, -K, -Ca, and -Mg treatments showed specific visual symptoms. However, -Fe and -B treatments showed no visual symptoms. After transplanting, early growth, photosynthesis, and root activity were significantly low in Ca- and Mg-deficient seedlings. From 8~10 days after transplanting, the B-deficient seedlings showed severe symptoms such as self topping and leaf malformation. Leaf area and dry weight of lateral vine were reduced in the order of control, -B, -Fe, -Mg, -Ca, -K, and -P at 4 weeks after transplanting. Total lateral vine number was the least in the B-deficient seedlings and early yield was less in the P-, K-, and Ca-deficient treatments than the others.

        노인의 자살생각에 영향을 미치는 요인에 관한 연구

        유영미 경찰대학교 2007 경찰학연구 Vol.7 No.2

        This study aims to present fundamental information for the preventive measures against the senior citizen's suicide, to lead the old to enjoy their remaining years cozily by close-examining the various factors influencing the old's suicide through the statistics about the suicide of the elderly persons, the analysis on the previous study, survey and so on. The conclusion of the study are as follows First, the old living in solitude are about 15% more than the old living with children. Second, the high blood pressure is the most painful disease to the old with the diabetes and the respiratory disease standing the next. Third, the surveyed old folks are suffering from the advanced depression. Both the family solidarity and the suicidal thoughts of them is middle level. Forth, the suicidal thoughts depend on the marital status, cohabitation, financial satisfaction, living standard, basic livelihood assistance, monthly allowance, hobby, chronic disease. Fifth, the more old folks are suffering from the depression, the more they are inclined for the suicidal thoughts, besides, the lower the family solidarity is, the more old folks show the tendency for suicidal thoughts. Finally, the study shows that basic livelihood assistance, depression, family solidarity are the major factors influencing the suicidal thoughts among the elderly persons. The solving way for the suicide of the old should be taken from that the senior citizen face the changed reality as it is. Moreover, It is recommended to make a deep research on suicidal thoughts of the old, depression, dementia, palsy continuously considering the increasing tendency for the preventive measures and welfare service of the old in solitude. Besides, It is really important to accept the problems related to the old as the public concerns on the basis of the principle of social solidarity. Therefore, It is warmly welcomed to introduce the long term medical treatment insurance for the elderly persons which enables the state and community to take good care of the old's disease such as dementia, palsy that has been entirely on the burden of family. These kinds of welfare system for the senior citizens should be scaled up and made further progress nationwide.
