‘Bristol Fairy’ 유래의 결실되는 아조변이체인 ‘Gyp99’의 실생계통으로 밝은 백색 겹꽃에 소화가 큰 ‘Gyp06-11’로부터 2008년 특성이 우수한 ‘Gyp08-2’ 계통을 선발하여 2009-2010년 2년 동안 특성평가 및 특성검정을 통해 ‘Dream Song’을 육성하였다. ‘Dream Song’의 초형은 직립형이고, 잎 모양은 피침형, 소화는 꽃잎수가 많고 암술이 2개인 백색겹꽃으로 꽃잎은 도란형, 꽃잎 끝 모양은 약간 둥근형, 꽃받침 모양은 컵형인 ‘Dream Song’ 고유의 특성을 가진다. 또한 소화의 일시개화성이 우수하고 절화수명이 매우 길며, 분지각이 작고 흰가루병에 강하고 총체벌레와 잎굴파리 등 충해에도 강해 재배적 가치가 높은 특성을 가진다. 준고냉지 여름절화 작형에서 ‘Dream Song’ 개화는 ‘Bristol Fairy’보다 17일 늦고 절간장과 화경장이 길었으며, 측지 분화가 많고 줄기가 굵었다. 또한 소화가 크고 야간 기온 22℃, 7일 이상의 고온조건에서도 기형화 발생이 없었다. ‘Dream Song’ is a cultivar of Gypsophila paniculata developed by the Jeollabuk-do Agricultural Research & Extension Services in 2010 for cut-flower production. This hybrid was bred from 121 seedlings collected from an open-pollinated population of ‘Gyp06-11’. It has novel morphological characteristics of upright plant type, lanceolate leaves, double florets with a few bright white-colored petals of obovate shape, truncate petal tips, and cup-shaped calyces. Furthermore ‘Dream Song’ has desirable cultivation characteristics including narrow branching angle, and moderate resistance to powdery mildew, thrips and leaf miners. Moreover it produces more primary branches, and longer internodes and flower stalks than reference cultivar ‘Bristol Fairy’ during summer cultivation in a subalpine area (500 m over the sea level). Flowering in ‘Dream Song’ is delayed by about 17 days as compared to ‘Bristol Fairy’. ‘Dream Song’ produces normal flowers with 2 pistils and an average of 10.4 stamens, with fewer malformed flowers than ‘Bristol Fairy’.

백락주,송진원,송기준,박광숙,최영주,강주일,이용주 대한감염학회 1997 감염 Vol.29 No.6

목적:국내 야서중에 한타바이러스의 숙주는 등줄쥐와 집쥐로 알려져 있으나, 한국에 서식하고 있는 다양한 야생 설치류를 채집하여 한타바이러스에 대한 항체검사를 실시하여 새로운 혈청형의 한타바이러스가 있는지를 혈청학적으로 규명하고자 하였다. 방법:국내에 서식하고 있는 야생 설치류를 1995년 10월부터 1996년 10월까지 7종 551수의 야시와 4종 97수의 소형동물을 채집하여 한타바이러스에 대한 항체검사를 간접형광항체법으로 실시하였다. 결과: 1) 야서 7종 551수와 소형동물 4종 97수를 대상으로 한탄바이러스의 감염율은 등줄쥐 17.2%(29/162), 흰넓적다리붉은쥐 8.7%(2/23), 대륙밭쥐는 25%(2/8), 그리고 땃쥐는 7.1%(1/14)이었다. 그리고 야생토끼는 8.8%(7/80)가 서울바이러스에 대한 항체를 가지고 있었다. 등줄쥐의 양성혈청중 대부분은 서울바이러스와 일부는 푸말라바이러스, 프로스펙트힐바이러스, 뉴욕바이러스와도 교차반응이 있었다. 흰넓적다리붉은쥐 2수와 대륙밭쥐 2수는 5가지 한타바이러스 모두에 교차 반응이 있었다. 2) 다람쥐는 9.5%(28/283)가 채집지역에 관계없이 한탄바이러스에 대한 항체를 가지고 있었고 항체기는 1:16 내지 1:256으로 비교적 낮았으며 서울바이러스, 푸말라바이러스, 프로스켁트힐바이러스와 뉴욕바이러스에 각각 반응하는 것도 일부는 교차반응을 보이는것도 있다. 청설모는 10.3%(7/68)가 한탄바이서르에 대한 항체를 가지고 있었으며 항체가는 1:16 내지 1:1,024이었으며 일부는 교차반응이 있었다. 3) 야생토끼의 서울바이러스에대한 항체양성율은 8.8%(7/80)이었으며 이중에 2수는 한탄바이러스와 교차반응이 있었고, 푸말라바이러스, 프로스켁트힐바이러스, 뉴욕바이러스와는 교차반응이 없었다. 항체가는 1:16 내지 1:64로 비교적 낮았다. 결론:등줄쥐는 한탄바이러스에 의한 감염이지만 흰넓적다리붉은쥐, 대륙밭쥐, 다람쥐 그리고 청설모의 일부는 한탄바이러스가 보다 다른 한타바이러스에 대한 항체가가 높았고 특히 일부 다람쥐 혈청은 푸말라바이러스 혹은 프로스켁트힐바이러스에만 반응하였다. 그리고 야생토끼는 서울바이러스에 대한 감염율이 높은 것으로 보아 국내에 한탄바이러스와 서울 바이러스 이외에 새로운 혈청형의 한타바이러스가 있는 것을 사료된다. Background: Hantavirus are widley distributed in rodents populations even in geographical areas where hemorrhagic fever with renal syndrome(HFRS) has not been reported. Multiple species of Murid and Arvicolid rodents serve as the natural reserviors of hantaviruses. Serologic diagnosis using hantaviral antigens indicates that hantaviruses are widley distibuted in wild rodents. This study were designed to find the distribution of hantaviruses among wild rodents and small mammals in Korea, 1995-1996. Methods: Rodents were trapped alive in selected areas. A total of 551 wild rodents from 7 species and 97 small mammals from 4 species were captured in Korea. Serologic evidence for hantavirus infection were tested using five hantavirus antigens by indirect immunofluorescent antibody technique(IFA). Among 162 Apodemus agrarius, 23 Apodemus peninsulae, 8 Clethrionomys regulus, 6 Microtus fortis, 1 Mus musculus, 283 Tamias sibiricus, 68 Sciurus vulgaris, 14 Crocidura laciura, 80 Lepus sinensis, 2 Capereolus capereolus and 1 Nyctereutes procyonoides. Results: 29 A. agrarius, 2 A. peninsulae, 1 C. laciura, 2 C. regulus, 27 T. sibiricus and 7 S. vulgaris were sero positive agaist hantaan virus and 7 L. sinensis were IF antibody positive against Seoul virus. Some of Tamias sibiricus were only seropositive against puumala virus or prospect hill virus. Conclusion: This data suggests that new serotypes of hantavirus might distribute among rodents in Korea.

송영동,이헌주,이병택,전병진,김학노 濟州大學校 産業技術硏究所 2001 산업기술연구소논문집 Vol.12 No.1

NTD (Pieutron Transmutation Doping) method has several advantages of high resistivity and uniform doping in comparison with other method. To satisfy those conditions. the flux variations of radial and axial directions should be within ±5 % and ±1.7%. respectively. The NTD facility in HANARO is purposed to irradiate the silicon ingot of 60cm in height. Hence. the flux flattener will be designed for 60cm. In this paper. preliminary study for optimal design is showed and the flux distribution of axial direction is calculated using MCNP4B code. The results show that the flattener model can flatten the flux to 83% of total length.

This study was conducted to investigate the effects of aerobic capacity on blood lactate changes after supramaximal progressive loaded exercise. The subjects were divided into Handball players(HB, n=6)group and Control(CT, n=6)group. All subjects exercised according to the protocol by bicycle erogometer. Blood lactate concentration was also measured during the test time. The RER values of CT group were relatively higher than that of HB group. In particular, the RER values of HR group at exercise 8 & 12min were significantly lower than that of CT group(P<0.05). The blood lactate concentration of HB group was significantly lower than that of CT group at 12min during the exercise(P<0.05). During the recovery times the blood lactate concentration of HB group were significantly lower than that of CT group. In addition, blood lactate clearance of HB group was also higher than that of CT group during the recovery time. From these results, it was suggested that lactate clearance during the supramaximal exercise may be affected by the level of endurance exercise performance.

Osteotome Sinus Floor Elevation Procedure를 이용한 임프란트 매식

송종운,조용기,박홍주,김영운,오희균,유선열 대한악안면성형재건외과학회 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.2

Maxillary sinus has an anatomic limitation to bone support available for dental implant. When there is less than 10㎜ of bone remaining between the upper alveolar ridge crest and the maxillary sinus floor, bone augmentation should be considered. In 1994, Summers reported two sinus floor elevation techniques of limmediate implant insertion, using osteotomes, for patients who have at least 5㎜ of bone remaining between the alveolar ridge crest and the maxillary sinus floor. One technique is osteotome sinus floor elevation (OSFE) procedure in which uses osteotomes to elevate the sinus floor. The other is bone-added OSFE (BAOSFE) procedure in which bone graft is added into osteotomy site. Both procedures conserve all of the remaining bone and selectively displace it upward, thereby raising sinus floor. This study was aimed to evaluate the long-term success rate of implants which had been placed by osteotome sinus floor elevation procedure. Between February 1996 and June 1998, 10 implants were placed using OSFE or BAOSFE procedures in 6 patients who had at least 6㎜ of bone remaining between the alveolar ridge crest and the sinus floor. OSFE procedures were performed in patiens, 2∼4㎜ sinus floor elevation was needed, whereas BAOSFE procedures were done in patines, more than 4㎜ sinus floor elevation was needed. During the mean follow-up period of 4 years 4 months (3 years 6 months ∼ 5 years 9 months), no implant was failed and all patients showed good functional results. OSFE and BAOSFE procedures seemed technically easier and less invasive compared to conventional sinus lift procedure. And both procedure have good success rate.

ΔQ는 1군≒2군≤4군≤6군≤3군≒5군 순이었다. ΔQ의 감소율은 1군과 2군, 4군과 6군, 3군과 5군이 각각 유사하였다. 4. ΔQ는 미세경도와 강한 양의 상관관계를 나타냈고(r=0.96, p<0.05), 침식깊이와는 강한 음의 상관관계를 보였다(r=-0.96, p<0.05). The aim of this study was to evaluate the preventive effect of commercially available anticariogenic products, specifically, the tooth cream containing Casein phosphopeptide-amorphous calcium phosphate(CPP-ACP), fluoride varnish and low-level fluoride mouthrinse on enamel erosion induced by carbonated beverage in a short period of time. Enamel specimens were treated as follows and were then kept in artificial saliva for 24 hours followed by further processing by alternately soaking them in Cola beverage and in distilled water for 1 minute each five times. Group 1: control group (no treatment) Group 2: tooth cream with CPP-ACP Group 3: fluoride varnish (1,000 ppm F) Group 4: low-level fluoride mouthrinse (227 ppm F) Group 5: fluoride varnish + tooth cream with CPP-ACP Group 6: low-level fluoride mouthrinse + tooth cream with CPP-ACP Microhardness and erosion depth were measured and the mineral loss of each specimen was evaluated by measuring the volumetric fluorescence change(ΔQ) against the stable fluorescent grid using quantitative lightinduced fluorescence(QLF). The experiment lasted for 6 days repeated each day. The results were as follows: 1. The microhardness was increased as follows: Group 1≤2≤4<6<3≒5. 2. The mean erosion depth was increased as follows: Group 5≒3<6<4≒2≒1. 3. The ΔQ was increased as follows: Group 1≒2≤4≤6≤3≒5. The decrement of ΔQ was similar between group 1 and 2, group 4 and 6 and group 3 and 5. 4. The ΔQ showed positive correlation with microhardness (r=0.96, p<0.05), while it was negatively correlated to erosion depth (r=-0.96, p<0.05).

The arterial supply to heart of mongolian gerbil has been described. Observations were made by the specimens injected with latex after the flowing through in left ventricle. The results were summaried as follows; 1. A. coronaria arose from the initial portion of Aorta in heart and A. coronaria dextra and sinistus arose in Aortic sinus on 10 specimens. A. coronaria sinistra arose more near boundary of Aortic sinus than A. coronaria dextra. 2. A. coronaria sinistra which arose from Aortic sinus divided into Ramus interventricularis sinistra and Ramus circumflexus sinistra. A. coronaria dextra which arose from Aortic sinus only runed continously as Ramus interventriculares dextra. 3. Ramus interventricular sinistra not reach the heart apex through the sulcus interventricula but stopped in thoracocostal plan extending to under part. 4. R. circumflexus runed theough sulcus coronarius, thereafter it runed from left ventricle to Sulcus interventricularis dorsalis. 5. A. coronaria dextra runed to diaphargm side through sulcus interventricula dorsi thereafter it became Ramus interventricular dextra. It distrubuted left and right ventricle wall on 8 specimens and 2 specimen stopped margo obtusus.
