최근 인터넷 사용자가 급증하면서 디지털 가전기기 간의 정보 공유를 가능케 하기 위한 홈 네크워킹 기술과 더불어 개인이 10m 내외의 단거리에서 사용하는 개인 무선 네트워킹 솔루선인 무선 PAN(Personal Aren Network) 기술이 주목을 받고 있다. 무선 PAN시스템은 홈 네크워크와 비교할 때 근거리에서 개인을 기준으로 하는 무선 네크워크라는 구분이 가능하며 에로서 Bluetooth, UWB(UltraWideBand), ZigBee등이 있다. 본 논문에서는 기존의 여러 가지 무선 PAN 시스템에 대해 개괄하고 새로운 무선 PAN 표준인 Binary CDMA (Code Division Multiple Access)를 이용한 Kononia 표준을 소개한다. 이 에는 물리층 및 데이터 링크층의 표준이 포함된다. 마지막으로 Koinonia 대모 시스템을 소개하며 무신 PAN 시스템으로서 Koinonia의 역할 및 미래에 대해서 서술한다.

화학 비료(제품명: 유에스칼) 섭취에 의한 위 협착 1예

조진웅,이용웅 대한소화기내시경학회 2003 Clinical Endoscopy Vol.26 No.6

Gastric stricture is caused by the ingestion of caustic materials, or by the involvement of a gastric infiltrating carcinoma. Corrosive injury-induced stricture is uncommon and the gastric injury caused by calcium fertilizer has not been reported in Korea. Once the diagnosis of gastric stricture is confirmed, an early definitive surgical intervention should be performed. Sometimes balloon dilatation on stricture may be attempted in suitable cases. We report a case of gastric stricture caused by ingestion of chemical fertilizer containing calcium and managed with radiologic balloon dilatation in a 73-year-old man. (Korean J Gastrointest Endosc 2003;26:435-438) 위 협착은 부식성 물질의 섭취에 의해 나타나거나, 침윤성 위암에 의해 광범위하게 위가 침범되었을 때 볼 수 있다. 하지만 최근에는 부식성 손상에 의한 위 협착은 드물고, 특히 칼슘 비료에 의해 나타난 경우는 국내에 아직 보고가 없는 실정이다. 치료는 수술이 원칙이지만, 경우에 따라서는 풍선 확장술을 이용하여 치료할 수 있다. 이에 저자들은 칼슘 비료를 음용한 73세 남자 환자에서 발생한 위 협착을 풍선 확장술을 이용하여 성공적으로 치료하였기에 문헌 고찰과 함께 보고하는 바이다.

본 연구는 이식 재배를 위한 건전 우량 인삼묘 생산을 위하여 해가림 내의 광량이 1년생 인삼의 광합성 및 형태적 특성에 대하여 조사하였다. 투과율에 따른 인삼의 엽록소 함량 및 광합성은 광 투과율이 높을수록 감소하는 경향을 보였으며, 광 투과율이 높은 조건은 잎이 생리적 장해를 받아 황변하는 모습을 보이고 있고, 줄기는 하피가 형성되었으며, 줄기의 유관속내 사부의 발달이 현저하게 위축되었다. 또한 뿌리는 광량이 높을수록 표피가 파괴되는 모습을 보였으며 형성층의 발달이 적었다. 뿌리 수량 역시 광 투과율이 높을수록 감소되었다. This study was conducted to response the photosynthetic rate and anatomical characters in one year ginseng plant against the light transmission ratio (10%, 20% and 30% in natural light) under shading materials by polyethylene (PE) net. The chlorophyll content and the photosynthesis of ginseng according to the light transmissivity showed decreasing trend as the light transmission ratio increased. At the higher light transmission ratio condition, leaves showed the chlorosis due to the physiological disorder, stems formed hypodermis, and phloem development inside the vascular tissue shrunk remarkably. Also, roots showed the epidermis destruction and less cambium development at the higher light intensity. The root weight also decreased as the light transmission ratio increased.

조진웅,김선익,성봉재,이가순,지무근,김수동,김현호 한국약용작물학회 2018 한국약용작물학술대회 발표집 Vol.2018 No.10

Background : This study examined EC in soil depending on leaking water rate of sun shading facilities and conducted experiments to establish the proper leaking water rate for ginseng depending on rainfall. Methods and Results : For leakage examination, rainfall flowing into a ridge. As sun shading facilities of ginseng to examine leakage, four kinds such as Blue-Pe-sheet, Pe4 (four–layered polyethylene net) + Pe2 (two–layered polyethylene net), Pe4, Pe2 were installed. As for leakage, a plastic box (23 × 30 × 30 ㎝) was installed on the ridge of ginseng field and outside, rainfall into the box during precipitation was examined, and the leakage quantity was calculated as the ratio of the quantity into the ginseng field regarding rainfall outside. The leakage quantity was examined a total of six times on July 2, July 3, August 24, August 30, August 31, and September 4. Regarding EC in soil, WT–1000n (www.rfsenser.co) which is a EC measuring instrument was used, and the average was calculated through 3 repeated examinations. There are little differences in the leakage quantity depending on the sun shading with 0.1% of the Blue-Pe-sheet, 2.3% of Pe4 + Pe2, 4.3% of Pe4, and 30.7% of Pe2. At the leakage rate of 0.1%, EC decreased from 1.52 ds/m on July 3 to 1.04 ds/m on August 8, and increased again to 1.54 ds/m on September 3 At the leakage rate of 2.4%, EC changes were lower than that of the leakage quantity of 0.1%, and similar results depending on periods were found. At the leakage rate of 4.3%, salt concentration was measured at 0.92 ds/m on July 3, decreased since then, increased to 0.90 ds/m on September 3, and overall concentration was less than 1.0 ds/m. At the leakage rate of 30.7%, EC was the lowest at 0.46 ds/m and similar results were found since then. Conclusion : The differences in leakage quantity depending on sun shading facilities of ginsengs affected EC in soil, and EC became lower with more leakage quantity. As for the leakage quantity to maintain the EC in soil proper for ginseng growth and development lower than 1.0 ds/m, it was found to be effective to control the leakage quantity at 30% in May - June, and September - October when there are less rainfall, and at 2 - 5% in July - August when there are heavy rainfall.

본 연구는 우리나라에서 보존하고 있는 구기자(Lycium chinesis Miller) 유전자원 131점의 잎과 줄기를 에탄올로 추출한 후 페놀화합물의 함량을 측정하여 비교 분석하기 위하여 수행되었다. 구기자 잎의 페놀 함량은 8.8~14.9mgg1을 보였으며 11.6~13.5mgg1 사이에는 약 60%의 유전자원이 분포되어 있었다. CB03286-89 유전자원은 총 페놀함량이 14.9±0.3mgg1으로 가장 높은 반면 CBP03310-250은 8.8±0.2mgg1으로 가장 낮은 함량을 보였다. 줄기에 대한 총 페놀함량은 6.8~12.4mgg1의 함량 범위를 보이고 있으며 잎보다는 상대적으로 다소 낮은 것으로 나타났다. 구기자 잎의 페놀화합물 중 33가지 물질을 정량 분석한 결과 China collection No.1에서 가장 높게 나타났으며 99797 수집종에서 가장 낮게 나타났다. (+)catechin 함량은 CB03286-89에서 가장 많았다. Myricetin은 Geumsan jaerae, Japan No.1, China collection No.1, CL32-13, CB04329-13, China collection No.12 그리고 CB03286-89 등에서 분석되었지만 나머지 구기자 유전자원의 잎에서는 검출되지 않았다. 줄기에 대한 페놀화합물은 잎에 비하여 상대적으로 함량이 적었으며 99797 수집종이 가장 많은 함량을 보였으나 CB04329-13에서는 가장 적은 함량을 보였다. (+)catechin 함량은 Japan No.1이 231.0±0.5ugg1으로 가장 높았으며, myricetin은 Japan No.1, China collection No.1, China collection No.12, CB03286-89 및 99797에서 분석되었지만 나머지 구기자 유전자원의 줄기에서는 검출되지 않았다. This study was conducted to determine the variation of phenolic compounds in the leaf and stem of 131 accessions of Lycium chinesis Miller. The levels of total phenolic compounds in the leaf of L. chinesis ranged between 8.8 to 14.9mg~;g-1 and among them 60% of the accessions belong between 11.6 and 13.5mg~;g-1 for the content of phenolic compounds in the leaf. The accession CB03286-89 contained the highest total phenolic compounds among the accessions tested, which was 1.7-fold higher than that of the lowest content accession CBP03310-250. In the stem, the total phenolic compound of 131 accessions of L. chinesis ranged from 6.8 to 12.4mg~;g-1 , showing slightly lower level than that in the leaf. The content of (+)catechin was highest in the leaf and stem of accession CB03286-89 and Japan No.1, respectively. Myricetin was detected in the leaf of seven accessions (i.e. Geumsan jaerae, Japan No.1, China collection No.1, CL32-13, CB04329-13, China collection No.12 and CB03286-89) and in the stem of five accessions (i.e., Japan No.1, China collection No.1, China collection No.12, CB03286-89 and 99797). Accessions had a great influence on the content of phenolic compounds. So, accessions-specific phenolic compound profiles might be helpful for commercial use or production of phenolic compounds in L. chinesis.

趙振雄,金忠洙,李錫榮 충남대학교 농업과학연구소 1993 농업과학연구 Vol.20 No.2

This experiment was carried out to investigate the competition in mono-and binary-associations of four forage species; ochardgrass (Dactylis glomerata L. cv. Potomac), tallfescue (Festuca arundinacea Scnreb, cv. Fawn), white clover (Trifolium repns L. cv. California), and red clover (Trifolium pratense L. c.v. Kenland) as affected by different sowing rate. Each species was grown in interspecific stands in field. And samplings of shoot were taken at first cliping stages. The interspecific competition was evaluated by calulating traditional methods: aggressivity, relative yield total (RYT), relative crowding coefficient (RCC). and compensation index (CI) with shoot dry matter production and calories of nutrient ingredient of each species in mono-and binary-mixture. Compared mixture with monoculture. RYT based on dry weight was lucrative in mixture except for orchardgrass-redcover (1:0.1,1:1) RYT of calculated calories with produced nutrients was in inlucrative in mixture of orchardgrass-redclover's 1:0.1 mixture by RYT<1.0. Generally, RYT was the highest in mixture of 1:0.5 sowing rate. Aggressivity of grass was poor competition tendency that raised up legume's sowing rate, particularly, with whiteclover. In grasses, tallfescue was stronger competitor than orchardgrass with legume in mixture, RCC of grasses against legume's growth was depressed in higher sowing rate with legume. Grass's growth depression was severer with whiteclover than redclover in mixture.
