Iris odesanensis Y.N. Lee is one kind of species among 54 endangered plant species designated by the Ministry of Environment in Korea. It is very rare native plant throughout the country. Therefore, this study was conducted to investigate the native Iris odesanensis in Mt. Naeyon for their distribution and ecological characteristics. They were mostly distributed mid-slope of the mountain from 443m to 498m altitude. They were located lower part of valley and provided enough humid condition. They had proper light and humidity conditions as they faced south south west, south south east, and south. They were also located at the places deciduous woody plants were distributed for proper light conditions for spring blooming. Iris flowered to use light at the period before the trees thickly covered with foliage. However this unfavorable light condition caused low percentage as 7.04% of blooming individuals in this study. In herbaceous, Viola chaerophylloides (Regel) W. Becker, Carex siderosticta Hance, Erythronium japonicum Decne., Oxalis obtriangulata Max., Hepatica asiatica Nakai, Lilium tsingtauense Gilg et cetera were appeared well. We propose that proper pruning of upper branches of the deciduous trees is needed for suitable light condition of management of native sites.

This report presents a voltammetric assay of dinitrotoluene using a DNA immobilized onto a carbon nanotube paste electrode (PE). The cyclic voltammetry (CV) and square wave (SW) stripping voltammetry parameters of the optimized conditions were obtained. An anodic peak current appeared at 0.3 V (versus Ag/AgCl) in a 0.1-M NH4H2PO4 electrolyte solution. The detection limit was found to be 0.6 ngL-1(S/N = 10), within a deposition time of 100 sec.

한국의 화훼산업은 1980년도부터 화훼류의 국내소비가 급증하게 되었고 그 수요를 충족시키기 위하여 화훼산업이 급진적으로 발전하였던 것은 사실이다. 그러나 농산물의 세계화에 따른 국내 생산의 차별화가 요구되는 시기이다. 따라서 생산적인 측면보다는 소비촉진에 관련한 연구가 매우 긴요한 시기일 것이다. 본 연구는 한국의 화훼소비 중에 잠재적 수요라 할 수 있는 일반수요의 촉진을 위해 결혼한 성인을 대상으로 그들의 소비형태 와 이용 동기에 기초 자료를 제공코자 하였다. 그 결과를 요약하면 다음과 같다. 첫째, 여성이 남성에게 가장 주고 싶은 선물은 꽃(41%)으로 가장 높았고, 여성에 있어서 자녀로부터 받고 싶은 선물은 37%로 꽃 선물이 가장 높았다. 둘째, 성인이 선호하는 화훼류는 전체적으로 난류(33.6%)>분화(25.1%)>분재(16.4%) 순으로, 여성은 남성과 달리 분화(32.5%)에 대한 선호도가 높았다. 그리고 화훼용도에서는 자가 장식용(66.7%)으로 구매하는 특성을 보였으며, 여성에 있어서는 더욱 현저하였다. 셋째, 성인의 선호 화훼류 형태는 난분(41.0%)>꽃다발(32.6%)>꽃바구니(22.3%)>꽃꽂이(3.0%) 순이고, 꽃선물 1회 비용에 있어서는 전체적으로 2만원(40.4%)을 사용하고, 여성은 남성에 비해 다소 높았다. 넷째, 성인의 이용동기에 있어 식물도입의 이유는 정서적(49.4%)>미적(38.4%)>공학적(8.2%)>건축적(2.8%) 순으로, 남성은 정서적(52.7%)에 대한 식물 도입의 동기가 가장 높았다. 또한 식물 도입이 아동에 미치는 영향은 정서적>미적>화목적>위생적>육체적 순으로 그 효과에 관하여 인식하고, 가정원예의 즐거움은 전반적으로 미감적>화목적>오락적>경제적ž위생적 순으로 인식하고 있었다. 성인의 화훼류 이용 동기에 관하여 요인분석은 효능 기능적 동기, 자기 지향적 동기, 타인 지향적 동기 그리고 사회적 상호적 동기로 4개의 집단으로 구별됨을 알 수 있었다. 결론적으로 화훼시장 정보의 중요성을 인식하면서 보다 계층적이나 연령적으로 세분하여 더 많은 연구가 필요할 것으로 생각된다.

Three rice cultivars, Namweonbyeo (early maturing), Hwaseongbyeo (medium maturing) and Dongjinbyeo (medium-late maturing) were trans-planted with 3 different seedling ages to investigate their growth habits and to improve the cultural method in paddy fields in the southern plain area of the Honam region in 1993. The 10-day old seedlings had more vigorous elongation of plant height and higher tillering ability but lower effective tiller rate, when compared with 35-day or 40-day old seedlings. Leaf area index and top dry weight were lower in 10-day old seedlings up to 40 days after transplanting but thereafter, were not different among seedlings ages. CGR was later in 10-day old seedlings, up to 30 days after transplanting, but in 30 to 40 days after transplanting, it was reversed. RGR was the highest in infant seedlings to 40 days after trans-planting, while in 50 days after transplanting, it was reversed. Panicle number and spikelet number per square meter were the highest in 40-day old seedlings, next highest in 35-day old seedlings and the lowest and in adult seedlings up to 40 days after transplanting, while spikelet number per panicle was vice versa. Milled rice yield did not vary significantly by seedling ages, but among the varieties, it was less in Hwaseongbyeo compared with Naweonbyeo and Dongjnbyeo.
