동부 ( Vigna unguiculata ) 의 종자 생산 요소에 미치는 모식물과 부식물의 영향

강혜순(Hye Soon Kang),이수진(Soo Jin Yi),장남기(Nam Kee Chang) 한국식물학회 1993 Journal of Plant Biology Vol.36 No.2

We investigated the effects of maternal and paternal parentage, and ovule position in a pod on seed development, weight, and progeny performance using an annual crop commonly called cowpea (Vigna unguiculata L.). The experiment was conducted in a greenhouse. Nine maternal parents were randomly selected, and 3 individuals were chosen as paternal parents based on the male fitness components. Five types of hand-pollination were attempted on each flower of the maternal plants to evaluate the influence of paternal identity. Independent variables such as parentage and ovule position affected the pattern of seed development. Ovules in the middle position of the pod exhibited a much higher probability of seed maturation than those at the stylar and basal positions, confirming the position effect. These independent variables also appeared to exert a significant effect on seed weight, although it was not possible to evaluate the relative importance of those variables due to significant interaction between parents. Mixed pollination tended to yield heavier seeds than other paternal parents. Ovules in the middle and basal end positions produced heavier seeds than those at the stylar and regardless of maternal and paternal parentage. Seed weight was independent of all measurements of progeny performance. At week 2 after germination significant paternal effects were found to be mediated through the ovule position in a pod. In particular, the progeny derived from self-pollination performed worse than the progeny from other paternal parentage. The progeny performance at week 4 after germination was affected by maternal parents independently of seed weight. These results show that paternal and maternal effects were quite consistent from the seed development to early growth of the progeny. Consequently, maternal and paternal effects on seed development and weight, and progeny performance may reflect, at least to some extent, genetic contribution of both parents. If so, it is possible for sexual selection on maternal and paternal function to generate the evolution of reproductive traits related to seed production.

A new technique involving gamma-spectrometry was used to determine the effects of pollination on mineral uptake in petals, ovaries and leaves of tulips and daffodils. A gamma-emitting radionuclide solution containing selenium-75, cesium-137, manganese-54, and zinc-65 was applied to the roots of tulips and daffodils growing in water. Mineral uptake was monitored in plant parts over a 24 day period. Pollinated tulip flowers showed a rapid withdrawal of minerals from the petals and an increase in ovary mineral content, while such a source-sink relationship was not established in daffodils. In both species, the concentration of most minerals in petals and ovaries declined prior to abortion of the plant part. The roots and bulbs of the plants contained the vast majority of the labeled minerals. This study demonstrated a possibility that certain plant parts could be isolated and monitored for mineral uptake over time without destruction.

The purpose of this study is to identify career barriers and career preparation behavior factors and to analyze the effect of the perceived career barrier on career preparation behavior types of college students majoring in Aviation·Tourism Service. Also, it intends to investigate the moderating effect of a grade level as most of Aviation·Tourism Service Departments belong to two-year colleges. The participants(N=744) were chosen from five different colleges in Korea. The major results were as follows. First, internal and external barriers such as parent’s objection, age, lack of career background, lack of interest and anxiety for the future were found to affect the process of participants’ career preparation. Second, their career preparation behavior types were divided into four groups such as Active Preparation Type, Surrounding Information Dependence Type, Credibility Gap Type and Action Oriented Type. Third, the moderating effect of grade level was confirmed ; the average score of sophomore students’ career barriers was higher than that of freshmen in the area of career preparation behavior, convenient information collection and career expert consultation. Especially, the difference between two groups was significantly showed in some career barriers such as information collection, age, lack of interest, economical situation, and parent’s objection. Finally, the implication of the study result and the limitation and future implication were suggested in the end.

강혜순 ( Hye-soon Kang ),박혜진 ( Hye-jin Park ),김현희 ( Hyun-hee Kim ) 한국환경농학회 2022 한국환경농학회 학술대회집 Vol.2022 No.-

국립농산물품질관리원(농관원)은 생산단계 농산물에 대한 잔류농약 안전성조사를 위해 식약처에서 고시한 농산물 등의 유해물질 분석법에 따 라 463종 및 4 0종 계열분석법 등을 정하여 사용하고 있으나, 인삼의 경우 수출 증진 및 국내 안전관리 향상을 위해 이 분석법에 대한 적용가능성 검증이 필요한 실정이다. 따라서 본 연구는 인삼 중 GC 대상 잔류농약 237종에 대한 다성분 분석법 적용시험을 수행하였으며 최적의 분석조건을 확립하고자 수행되었다. 인삼 중 수삼, 건삼, 홍삼을 시료로 사용하였으며 표준물질 주가 후 acetonitrile로 추출 및 정제하여 GC-MS/MS로 분석하였다. 분석결과 chlorothalonil, dichlofluanid, folpet, iprodione은 정성만 가능하였으며, 그 외 농약들의 검량선 R2값은 0.99 이상, 회수율 CV(%)값은 20% 미만, 정량한계는 0.01 mg/kg 이하, 회수율범위는 70∼120%를 만족하여 정성 및 정량이 가능함을 확인하였다. Chlorothalonil의 경우 수삼과 홍삼에서, dichlofluanid는 수삼, 건삼, 홍삼, folpet은 홍삼, 그리고 iprodione은 건삼과 홍삼에서 회수율 범위를 만족하지 못했다. Chlorothalonil 등 4종에 대한 정량분석을 위해 1% formic acid 함유 acetonitrile로 추출한 후 회수율을 분석한 결과, chlorothalonil, dichlofluanid, folpet, iprodione 각각 건삼의 경우 평균 73.7, 92.7, 85.7, 89.1%, 홍삼의 경우 99.2, 98.5, 101.6, 115.7%로 회수되어 정량분석이 가능함을 확인하였다. 수삼의 경우 iprodione(114.5%)을 제외하고 chlorothalonil은 16%의 회수율을 보였으며 dichlofluanid와 folpet은 회수되지 않아 분석법 개선이 필요하였다. 우선 이 농약들의 낮은 회수율이 수삼 중 미지의 간섭물질로 기인한다고 판단하여 수삼의 시료량을 5g으로 줄이고 물 10ml를 가한 후 1% formic acid 함유 acetonitrile로 추출하였다. 실험결과 chlorothalonil, dichlofluanid, folpet의 회수율은 각각 평균 66, 7, 39%로 나타났다. 또한 3종 농약의 pH에 따른 안정성을 고려하여 수삼 5g에 물대신 1% formic acid가 함유된 물로 습윤화한 후 1% formic acid 함유 acetonitrile로 추출하였다. 회수율 분석결과 chlorothalonil, dichlofluanid, folpet 각각 92.0∼97.7, 95.1∼101.7, 90.9∼107.6%로 정량을 위한 만족한 회수율 범위를 나타내었다. 본 연구결과, 인삼 중 수삼, 건삼, 홍삼에 대한 237종 잔류농약분석 시 농관원이 마련한 다성분 분석법 적용이 가능할 것으로 판단된다. 다만, chlorothalonil 외 3종에 대한 정량 분석을 위해서는 추출용매를 산성으로 조절이 필요하며, 특히, 수삼의 경우 시료량 조절 및 산성화 된 물로의 습윤화 등 pH 조절을 통한 정량분석이 가능할 것으로 사료된다.

강혜순(Kang Hye soon) 영상영어교육학회 2010 영상영어교육 (STEM journal) Vol.11 No.1

The purpose of this study is to expand advanced students' English proficiency by developing their background knowledge in current affairs. In order to build up such integrative background knowledge about current issues, traditional English reading or listening classes should be modified. This study shows an integrative and interactive model of developing four language skills in English based on using multimedia power-point slides and focusing on current affairs. One of the advantages of using multimedia power-point slides is to provide authentic materials for students. Using articles from the Korea Herald or the Korea Times, the class uses power-point slides which focus on politics, economics, arts, and culture. The model is expected to endow students with background knowledge to help in preparing for careers after college graduation while also advancing their current level of English proficiency a few steps by expert scaffolding in small group activities. This teaching model using multimedia power-point slides is based on three key factors: authenticity of teaching materials, student-oriented English classes, and Vygotsky's theory of expert scaffolding.

제주 생물권보전지역 내 한라산국립공원의 경관분석: 단편화 현상

강혜순 ( Hye Soon Kang ),김현정 ( Hyun Jung Kim ),장은미 ( Eun Mi Chang ) 한국환경생태학회 2008 한국환경생태학회지 Vol.22 No.3

도로는 생태계를 교란시키는 인간 활동의 지표이며 흔히 서식지 단편화, 서식지 축소, 서식지 고립을 유발한다. 제주도의 한라산국립공원(면적=153.4km2)은 지형 지질 생물상의 특이성이 높으며 유네스코 생물권보전지역(MAB)의 핵심지역으로도 중복지정되어 있다. 공원의 이러한 높은 보전가치가 많은 탐방객과 도로건설을 유도하고 있음에도 불구하고 도로로 인한 경관의 변화는 거의 알려진 바가 없다. 본 연구에서는 GIS를 활용하여 한라산국립공원의 도로로 인한 서식지 단편화 양상을 공원 용도지구, 해발고도, 식생에 관련하여 분석하였다. 포장도로와 법정ㆍ비법정탐방로에 각각 112m, 60m 버퍼를 적용시킨 결과 한라산국립공원은 총 100개의 단편으로 나뉘었다. 포장도로와 법정탐방로만을 고려했을 때 드러난 10단편의 면적은 0.002km2-38.2km2(평균면적=14.2km2)에 이르렀고 자연보존지구와 자연환경 지구 모두에서 각기 약 7%가 가장자리로 판정되었다. 이들 단편의 형태지수 평균은 5.19(100단편 중), 1.22(10단편중)이었지만 공원의 동서 양단과 정상부근에 있는 단편들의 형태지수가 보다 높았다. 5개의 법정탐방로가 모두 분화구까지 연결되어 있고 고도가 높아짐에 따라, 활엽수림, 침엽수림, 초지로 식생이 전환되기 때문에 높은 고도, 특히 고유식물과 고산식물이 많은 고도 1,400 m이상의 초지에서 서식지 면적이 현저하게 감소했다. 이런 결과는 한라산국립 공원도 도로로 인한 서식지 단편화를 겪고 있으며, 단편화로 인한 서식지 악화와 서식지 소실의 위험이 공원의 자연환경 지구보다 한라산 정상의 백록담을 중심으로 하는 자연보존지구에서 더 높을 수 있음을 보여준다. 따라서 한라산국립공원의 현 도로망은 생태계 보전과 보호라는 국립공원의 목표에 부합하지 않는다고 사료된다. 한라산국립공원 전체가 또한 MAB 핵심지역임을 고려한다면, 공원 용도지구의 재설정과 단편화를 완화시키기 위한 공원 내 도로관리에 보전노력이 경주되어야 할 것이다. Roads are an indicator of anthropogenic activity causing ecosystem disturbances and often lead to habitat fragmentation, habitat loss, and habitat isolation. The Hallasan National Park(153.4km2) on Jeju Island being distinguished for its unique geology, topography, and biota has also been designated as a core area of UNESCO Man and the Biosphere(MAB) Reserve. Although the high conservation value of this park has contributed to a rapid growth of tourists and road construction, landscape changes due to roads have not been examined yet. We used GIS systems to examine the fragmentation pattern caused by roads, in relation to its zonation, elevation, and vegetation. When a buffer was applied to roads(112m width for paved roads and 60m width for both legal and illegal trails), the park consisted of 100 fragments. The ten fragments generated after applying buffer to only paved roads and legal trails ranged from 0.002km2 to 38.2km2 with a mean of 14.2km2, and about 7% of both nature conservation zone and nature environment zone of the park were edge. Fragments in both east and west ends of the park and around the summit exhibited relatively high shape indices with means of 5.19(for 100 fragments) and 7.22(for 10 fragments). All five legal trails are connected to the pit crater of the mountain and vegetation changed from broadleaf forests and conifer forests to grasslands with elevation, consequently resulting in dramatic fragment size reduction in grasslands at high elevation, in particular above 1,400m, where endemic and alpine plants are abundant. These results show that in Hallasan National Park the risks of habitat deterioration and habitat loss due to fragmentation may be more severe in the nature conservation zone dominated by Baengnokdam than in the nature environment zone. Therefore, current road networks of the park appear to fall short of the goal of the national park for ecosystem conservation and protection. Considering that the entire Hallasan National Park also serves as aMAB core area, conservation efforts should focus, first of all, on park rezoning and road management to mitigate habitat fragmentation.

EFL 듣기 과정에서의 상위인지 자각과 학습책략

강혜순(Kang Hye soon) 영상영어교육학회 2007 영상영어교육 (STEM journal) Vol.8 No.1

Metacognitve awareness has been referred as an important factor in the effective process of EFL/ESL listening in many studies. Metacogntion consists of two aspects; knowledge about cognition and the executive or regulatory function. A successful learner seems to know what a learning strategy is, and how to use that strategy to improve his/her learning process, and whether or not a certain strategy is working effectively. If a learner is not aware of when a problematic situation happens in the learning process and what he or she can do to fix it, he/she can not take any remedial action. Therefore, this study investigated metacognitive awareness of EFL learners in the listening process. It showed that there existed a significant relationship between listening ability and metacognitive awareness. Also, this study focused on the variety of strategies used by EFL learners in the listening process. It revealed that listening ability is significantly related with types of learning strategies used by a learner in the listening process. Especially, successful learners used more direct strategies than indirect strategies suggested by Oxford(1990). In conclusion, this study showed the appropriate instruction of developing metacognitive awareness of EFL learners and the well-structured training of improving learners' use of effective strategies are needed.
