The present study was performed to investigate the effects of the colchicine concentrations on chromosome doubling for producing of tetraploid plants of Codonopsis lanceolata, and its effect on plant morphology. A total of 180 individuals germinated from 16 treatment groups, were exposed to various concentrations (0.05-1.0% w/v) of colchicine for different soaking duration (3-24 hour). The highest numbers of tetraploid plants (3) were observed from the lowest concentration of colchicine (0.05%), and one (1) tetraploid plant was obtained from the 0.5% concentration group with a 6 hour treatment. However, no tetraploid individual was observed in any other treatment groups. The plant height of the diploid (18.1 ㎝) was slightly shorter than that of the tetraploid (13.4 ㎝). The fresh weight of the main root in the diploid (0.5 g) was four-fold higher than the tetraploid (2.2 g). The colchicine-treated plant regeneration rate in C. lanceolata was decreased when the plants were subjected to high concentration of colchicine. In particular, the highest number of tetraploid plants (5 and 3) was obtained from the lower concentration (0.05% and 0.1%) of colchicine for 6-hour treatment, which were a higher rate (29.4% and 30%) of regenerated tetraploid plants than other regenerated plants. As in the seed treatment result, the plant height of the diploid was significantly higher (10.4 ㎝) than tetraploid. The higher morphological changes were observed comparatively from tetraploid plants than the diploid.

Purpose: To evaluate the clinical and microbiological effects of the local use of egg yolk immunoglobulin against Porphyromonas gingivalis (anti-P.g. IgY) as an adjunct to scaling and root planing (SRP) in the treatment of moderate to severe chronic periodontitis. Methods: This was a randomized, placebo-controlled, double-blind trial involving 60 systematically healthy patients with moderate to severe chronic periodontitis. Subjects (n=20/group) were randomly assigned to receive SRP combined with subgingival irrigation of anti-P.g. IgY and anti-P.g. IgY mouthwash, subgingival irrigation of 0.2% chlorhexidine and 0.2% chlorhexidine mouthwash, or subgingival irrigation of placebo and placebo mouthwash for 4 weeks. Probing pocket depth, clinical attachment level, bleeding on probing, and the plaque index were evaluated at baseline and at 4 weeks. Subgingival plaque, gingival crevicular fluid, and saliva were simultaneously collected for microbiological analysis. Results: Our results showed that anti-P.g. IgY mouthwash was as effective as chlorhexidine at improving clinical parameters over a 4-week period. All the groups showed a significant reduction in levels of P.g. at 4 weeks. No significant difference was observed in the test group when compared to placebo regarding the reduction in the levels of P.g. Anti-P.g. IgY significantly suppressed the numbers of red complex bacteria (RCB) in subgingival plaque and saliva in comparison with placebo. No adverse effects were reported in any of the subjects. Conclusions: Within the limitations of the study, the present investigation showed that passive immunization with anti-P.g. IgY may prove to be effective in the treatment of chronic periodontitis due to its ability to improve clinical parameters and to reduce RCB. No significant differences were found between the anti-P.g. IgY and placebo groups in the reduction of P.g.

현재까지 알려진 가장 효율적인 인수분해 방법은 General Number Field Sieve (GNFS)를 이용하는 방법이다. CADO-NFS는 GNFS를 기반으로 구현된 공개된 소프트웨어로 RSA-704의 인수분해에 사용된 도구이다. CADO-NFS에서 다항식 선택은 크게 다항식을 생성하는 과정과 이를 최적화하는 과정으로 나누어져 있다. 그러나 CADO-NFS에서 다항식의 최적화 과정은 전체 다항식 선택 소요 시간 중 약 90%를 차지할 정도로 큰 부하를 주고 있다. 본 논문에서는 사전 연산 테이블을 이용하여 다항식 최적화 과정의 부하를 줄이는 방안을 제안한다. 제안하는 방법은 기존 CADO-NFS의 다항식과 같은 다항식을 선택하지만, 다항식 선택에 걸리는 시간은 약 40% 감소한다.

정부의 신 재생에너지 분야 투자확대정책과는 달리 08년 발전차액지원 기준가격이 인하된 이후 태양광사업의 추진 건수가 대폭 감소되는 양상을 보이고 있다. 이는 전세계적 금융위기에 따른 재원조달의 어려움이 근본적 원인이기도 하지만, 현행 발전 차액지원 기준가격체계가 적정하지 못한데도 그 원인을 찾을 수 있다. 본 연구에서는 입지와 형식별로 여러 대안을 설정하고, 비용 및 수익의 변동 리스크를 반영하는 기준가격 산정모델(Cost & Benefit Risk Based Purchase Price Process Model : CBRP3 Model)을 제안한다. 발전설비 대안별로 투자비와 발전량의 변동데이터를 산출하여 재무템플릿에 입력한 후 시뮬레이션을 실행하여 대안별 발전원가의 확률분포를 도출하고, 이를 기반으로 기준가격체계를 도출한다. 도출된 기준가격체계와 현행 발전차액지원 기준가격체계를 비교하고, 향후 연구과제를 제시한다.

Glanzmann's thrombasthenia is a Qualitative platelet disorder characterized by a deficiency in the platelet membrane glycoproteins IIb/IIIa. It belongs to a group of hereditary platelet disorders typified by normal platelet numbers and a prolonged bleeding time. The severity of bleeding does not correlate with the severity of the platelet glycoprotein IIb/IIIa a abnormality. The present case report describes the periodontal treatment of a patient with Glanzmann's thrombasthenia. A 30-year-old female with a history of Glanzmann's thrombasthenia was referred for gingival bleeding on tooth brushing and discomforts in #38 area. The periodontal finding revealed a diagnosis of localized slight adult periodontitis. Root planing and extraction of #38 was performed under 12 pack of platelets transfusion and digital compression was done for hemostasis. The gingival bleeding ceased within a day in maxilla and 2 days later in mandible. 42 pack of platelets was administered for 3 days of post-treatment and for iron-deficiency anemia 3 pack of RBCs was transfused 2 days later. 1 week later the inflammation in gingiva disappeared and gingival stippling appeared. The clinical result we got was good and in such a medically compromised patient it is an ability to maintain a proper oral hygiene that is essential both for oral and systemic health.

The full-scale measurements are compared with the wind tunnel test results for the long-span roof latticed spatial structure of Shenzhen Citizen Center. A direct comparison of model testing results to full-scale measurements is always desirable, not only in validating the experimental data and methods but also in providing better understanding of the physics such as Reynolds numbers and scale effects. Since the quantity and location of full-scale measurements points are different from those of the wind tunnel tests taps, the weighted proper orthogonal decomposition technique is applied to the wind pressure data obtained from the wind tunnel tests to generate a time history of wind load vector, then loads acted on all the internal nodes are obtained by interpolation technique. The nodal mean wind pressure coefficients, root-mean-square of wind pressure coefficients and wind pressure power spectrum are also calculated. The time and frequency domain characteristics of full-scale measurements wind load are analyzed based on filtered data-acquisitions. In the analysis, special attention is paid to the distributions of the mean wind pressure coefficients of center part of Shenzhen Citizen Center long-span roof spatial latticed structure. Furthermore, a brief discussion about difference between the wind pressure power spectrum from the wind tunnel experiments and that from the full-scale in-site measurements is compared. The result is important fundament of wind-induced dynamic response of long-span spatial latticed structures.

Hwangryunagyotang is supposed to have significant effects on some sorts of cardiovascular diseases like atherosclerosis. For this study. ACAT inhibitor was put in LDLR -/- mice to derive free cholesterol from it. This was to examine the effectiveness of Hwangryunnagyotang on its protecting and recovering function with endothelial cells damaged by free cholesterol through experimental. The results reported below. Hwangryunagyotang suppressed the crystallization of reactive oxygen species in macrophages and the numbers of free cholesterol crystal plate structured and reduced fragmentation of nucleus in ECV 304 cell strain by ACAT inhibitor significantly. Hwangryunagyotang also suppressed the necrosis of tissue in LDLR -/- mice' (treated with ACAT inhibitor) inflammatory portion which is adjacent to aortic root, proximal aorta and carotid artery by immunohistochemistry and fluorescence microscopy. On the whole, Hwangryunagyotang suppressed the necrosis of endothelial cells and especially it's effcet for the necrosis of para-myocardial tissues by free cholesterol. With this result, I suggest Hwangryunagyotang might have protective and recovery effects on atherosclerosis, so we need to carry on this study henceforth clinically and experimentally as well.
