This study was carried out to determine optimum harvest time of in vitro multiplied tuber Pinellia ternata(Thunb.)Breit from 1990 to 1992. Tuber yield and its related traits were observed with four harvest times. Plant height was 7.2cm at 6 months and 19.3cm at 24 months after planting. The number of tubers per unit area was significantly increased with the passage of growing time after planting$(78\;tubers/m^2)$, those were increased by 2.3 times in 6 months, 5.6 times in 12 months, 13.3 times in 18 months and 20.0 times in 24 months. The tuber sizes(length, width and weight) were highly enlarged during 12 to 18 months after planting compared with before or after this time. There were smaller tubers and lower tuber yields with shorter growing period, while large tubers above 7.1mm and higher yields with longer growing. It was suggested that the optimum harvest time was 18 months after planting, before over wintering rather than next year of spring, 24months after planting.

정태열(Jung, Tae Yeal),박문수(Park, Mun Su) 대한부동산학회 2021 大韓不動産學會誌 Vol.39 No.2

본 연구는 분당의 중앙공원에 대한 풍수적 입지를 평가하고, 공원 주변의 아파트 단지별 가격이 풍수적인 영역에 따라서 어떠한 영향을 미치는지를 규명하는 데 그 목적이 있다. 동양과 한국사회에서 오랜 시간 동안 풍수라는 실용학문은 도읍지나 군현(郡縣)의 대지(大地)는 물론 씨족 공동체나 개인의 사생활을 위한 소지(小地)를 선점하는 상지술(相地術)로 자연의 공간을 대상으로 활용되었다. 본 연구는 분당신도시 중앙공원 인근 아파트 단지를 중심으로, 풍수 입지가 부동산가치에 미치는 영향에 초점을 두었다. 본 연구는 사례 검증을 통하여 다음과 같은 결괏값을 얻었다. 첫째, 용(龍배)의 배산임수 입지는 부동산가치에 긍정적인 영향을 미친다. 둘째, 혈(穴)의 백호 중심입지에 있을수록 부동 산가치에 더 긍정적인 영향을 미친다. 셋째, 사신사의 경쟁우위 입지가 상대적으로 부동산가 치에 긍정적인 영향을 미친다. 넷째, 내당수, 탄천과의 합수되어 현무 뒤로 사라지는 수세는 부동산가치에 긍정적인 영향을 미친다. 다섯째, 안정화된 안산의 중앙공원은 부동산가치에 긍정적인 영향을 미친다. The purpose of this study is to evaluate the location of Feng Shui in the central park in Bundang-gu, Seongnam-si, and to find out how the value of each apartment complex near the park is affected by the Feng Shui location. For a long time in Eastern and Korean society, the practical study of Feng Shui has been used as a point of view of preoccupying not only large lands in capital cities and towns, but also small lands for clan communities and individual privacy. This study focused on whether the Feng Shui location affects the property value, focusing on the apartment complex near the Central Park in Bundang new town. This study obtained the following results through case verification. First, the location of ‘Dragon(龍), mountain in the front’ has a positive effect on property value. Second, the more ‘hyeol(穴), Center Baegho’ locations are, the more positively the property is. Third, the competitive advantage location of ‘Sasinsa(四神沙)’ has a relatively positive effect. Fourth, the river condition that ‘Naedangsu’ combined with Tancheon is disappearing behind ‘Hyeonmu’ has a positive effect on property value. Fifth, the location of ‘Ansan’ providing a well-established location, has a positive effect on property value.

本 실험은 林間草地의 改良과 管理 및 利用에 관한 基鍵資料를 얻고자 趣光程度를 0%區(無週光區), 25%, 50%, 75%로 인위적으로 조절하고. orchard grass, timothy, perennial ryegrass, ladino clover를 供試하여, 일반成分, 세포벽構成物質(CWC),,消化率, 可溶性탄수化物 (WSC) 함량 및 실산유실요 (NO, - N) 含量등을 分析하였으며 1985년도 축산시험장 草地시험포에서 수행되었다. 1. 一般成分과 CWC含量 및 消化率을 고려해 볼 때 ladino clover가 화본과목장에 비해 품질이 좋았으며, 未本科목장중에서는 perennial ryegrass의 品質이 좋았다. 2.粗蛋白質, 조회분 및 消化率은 草種에 관계없이 차광을 많이 할수록 增加하였으며, 粗織維系 統은 차광을 많이 할수록 未本科救草에서는 減少하였으나 ladino clover에서는 오히려 曾加하였다. 3.利用時期에 따른 목초의 消化率은 봄철에 자란 목초는 여름철 고온조건하에서 자란 옥초에 비해 良好하였다. 4.草種別 WSC 含量은 perennial ryegrass>ladino clover$\geq$orchardgrass$\geq$timothy 順이었으며 차광을 많이 할수록 WSC含量은 減少하여 (P< 0.05) 無遮光區$\geq$25%週光區$\leq$50%차광구$\geq$75%차광구 순 이었다. 5.草種別 NO,-N 含量은 perennial ryegrass orchardgrass ladino clover timothy 順이었으며, 차광을 많이 할수록 $NO_3$-N含量은 급격히 增加하 여 (P< 0.05) 75%차광구>50%차광구 25%차광구 無차광구 순이었다. 차광정도와 $NO_3$-N 함량과의 회귀식에서($r^2$=0.90**,$r^2$=0.95**) 43~44% 이상의 차광은 실산중독 위험수준 이상이었다. 6. 以上의 결과로서 임간초지개랑시에는 가축에게 실효중독을 야기시키지 않고 목초의 품질과 수량등을 고려한 한계 차광정도는 40%정도(자연광량의 60% 以上 受光條件)로 생각된다. A field experiment was conducted to determine the effects of shading degrees (0: full sunlight, 25, 50 and 75%) on the proximate components, cell wall constituents (CWC), digestibility, water soluble carbohydrates (WSC) and nitrate nitrogen ($NO_3$-N) concentration of grasses grown in forest. For the test different artificial shading houses were established and pasture species used were orchardgrass, timothy, perennial ryegrass and ladino clover. The experiment was performed at LES in Suwon. 1985. 1. Considering proximate components, CWC and digestibility of grasses, ladino clover showed the best quality, and then perennial ryegrass. 2. The contents of crude protein, crude ash, and digestibility of grasses were increased with shading, regardless of pasture species. As the shading degrees are increased, the contents of crude fiber in orchardgrass, perennial ryegrass and timothy were decreased, while that in ladino clover was increased with shading. 3. Grasses grown in spring showed higher digestibility than those grown in summer season. 4. The content of WSC was the highest in perennial ryegrass, and then ladino clover, orchardgrass, and timothy, in that order. Also WSC was decreased as the shading degrees are increased. 5.The content of $NO_3$-N was the highest in perennial ryegrass, and then orchardgrass, ladino clover and timothy, in that order. Also the $NO_3$-N was significantly increased with higher shading level. In the regression equation between shading degrees and $NO_3$-N ($r^2$=0.90**, $r^2$=0.95**), shading degree of 43 to 44% was critical level, causing nitrate poisoning to animal. 6 Considering grass quality, dry matter yield and $NO_3$-N, less than 40% of shading degree (over 60% of full sunlight) was desirable for better grassland improvement, management and utilization in the forest.

박문수,김영준,Park, Moon-Soo,Kim, Young-Jun Korean Academy of Orofacial Pain and Oral Medicine 2007 Journal of Oral Medicine and Pain Vol.32 No.4

Destruction of oral soft and hard tissues and resulting problems seriously affect the life quality of xerostomic patients. Although artificial saliva is the only regimen for xerostomic patients with totally abolished salivary glands, currently available artificial salivas give restricted satisfaction to patients. The purpose of this study was to contribute to the development of ideal artificial saliva through comparing viscosity and wettability between CMC solutions and human saliva. Commercially-available CMC is dissolved in simulated salivary buffer (SSB) and distilled deionized water (DDW). Various properties of human whole saliva, human glandular saliva, and a CMC-based saliva substitutes known as Salivart and Moi-Stir were compared with those of CMC solutions. Viscosity was measured with a cone-and-plate digital viscometer at six different shear rates, while wettability on acrylic resin and Co-Cr alloy was determined by the contact angle. The obtained results were as follows: 1. The viscosity of CMC solutions was proportional to CMC concentration, with 0.5% CMC solution displaying similar viscosity to stimulated whole saliva. Where as a decrease in contact angle was found with increasing CMC concentration. 2. The viscosity of human saliva was found to be inversely proportional to shear rate, a non-Newtonian (pseudoplastic) trait of biological fluids. The mean viscosity values at various shear rates increased as follows: stimulated parotid saliva, stimulated whole saliva, unstimulated whole saliva, stimulated submandibular-sublingual saliva. 3. Contact angles of human saliva on the tested solid phases were inversely correlated with viscosity, namely decreasing in the order stimulated parotid saliva, stimulated whole saliva, unstimulated whole saliva, stimulated submandibular-sublingual saliva. 4. Boiled CMC dissolved in SSB (CMC-SSB) had a lower viscosity than CMC-SSB (P < 0.01 at shear rate of $90s^{-1}$). 5. For human saliva, contact angles on acrylic resin were significantly lower than those on Co-Cr alloy (P < 0.01). 6. Comparing CMC solutions with human saliva, the contact angles between acrylic resin and human saliva solutions were significantly lower than those between acrylic resin and CMC solutions, including Salivart and Moi-Stir (P <0.01). The effectiveness of CMC solutions in terms of their rheological properties was objectively confirmed, indicating a vital role for CMC in the development of effective salivary substitutes.
