트래픽 분석에 의한 n-차원 벡터 기법을 사용한 침입 탐지
신수복 ( Soo-bok Shin ),김원일 ( Won-il Kim ),예홍진 ( Hong-jin Yeh ) 한국정보처리학회 2005 한국정보처리학회 학술대회논문집 Vol.12 No.1
인터넷의 급속한 발달과 그 중요성이 날로 증가하면서 인터넷은 우리생활의 일부가 되었다. 따라서 네트워크에서 환경에서의 침입은 빠르게 증가하고 있으며 그 피해 또한 커지고 있다. 서비스 거부공격, 분산서비스거부 공격, 웜 등은 악의적인 의도로 호스트나 네트워크의 자원을 고갈 시키는 등 심각한 문제를 초래하고 있다. 또한 중요한 서버의 공격으로 인해 시스템이 다운되면 서비스를 하지 못하게 됨으로 사용자에게 불편을 초래할 뿐만 아니라 막대한 비용의 손실도 발생한다. 따라서 본 논문에서는 벡터를 이용하여 지역 네트워크망으로 들어오는 트래픽의 비정상 증가를 분석함으로 침입을 탐지하고 위험수위를 결정하는 방법을 제안한다.

Gastric cancer is rarely associated with pregnancy and its incidence is reported to be 0.1%. The dilemma in the treatment of this rare occasion is that it is usually diagnosed at an advanced stage. The most common reason for delayed diagnosis is that early symptoms of gastric cancer, such as nausea, vomiting and epigastric discomfort, are nonspecific and usually misinterpreted as those related to pregnancy. Clinicians` reluctance to request diagnostic studies is another reason for delayed diagnosis. So these make the prognosis much worse. We must consider the rare possibility of gastric cancer in case of persistent nausea and vomiting. We report a case of advanced gastric cancer diagnosed by gastroscopic examination performed in the second trimester because of persistent nausea and vomiting.

21plants, which collected from Korea and Japan, were applied to antitumor and cytotoxic screening tests against sarcoma 180 a ascitec in mice. The results are summariged as follows : 1) The total packed cell volume method has been used for the antimeoplastic screening for from natural higher plants in Korea. By this method, we have found out that Selaginella involves, Patrinia hispida, Archyranthes japonica and Solanum nigrum having significant activity and also Cydonia sinensis and Rubia akane showed slight activity to antitumor 2) The total packed cell volune method has been used for the antineoplastic screening for from natural higher plants in Japan. Among the 21 tested plants, lsodon japonicus having strong antitumor activity and also Torilis japonica, Aralia elata, Leonurus sibiricus and Rubia cordifolia showed significant activity to anticancer tumor while Forsythia spp and Solanum nigrum showed slight activity to antitumor. 3) Among the 21 tested Korea plants, lsodon excisus and Forsythia Koreana showed strong antitumor activity by the V79 cytotoxic cell screening test.

The purpose of this in vitro study was to compare the apical leakage in extracted teeth filled with gutta-percha subsequent to dressing with one of three different calcium hydroxide preparations. Thirty six extracted teeth with single canal were sued in this study. After working length determination, canals were prepared with K flexo files to a #40 at the working length. Step-back flaring was produced by using #45, #50 K flexo files and #2, #3, #4 Gates Glidden burs. The teeth were randomly divided into 3 groups of 10 each: the remaining six teeth were used for negative and positive leakage control: Group 1, dressed with pure calcium hydroxide power (Sigma, USA) mixed with distilled water; Group 2, dressed with Metapaste (Metadent, Korea); Group 3, dressed with Vitapex (Neo Dental, Japan). Teeth were sealed with Caviton (GC, Japan) and incubated in 100% humidity, at 37℃ for 1 wk. All kinds of calcium hydroxide were removed from the canal with a MAF and 5% NaOCI. The canals were filled with AH-26 sealer and gutta-percha using lateral condensation technique, incubated in 100% humidity, at 37℃ for 2 days for the sealer to be set. The teeth were coated twice with nail varnish except for an area of approximately 2mm surrounding the apical foramen. All specimens were placed in 2% mthylene blue solution for 2 days. The root were sectioned longitudinally, the amount of apical leakage was measured to the most coronal part of the root canal to which the dye had penetrated. The independent measurements were made for each root using a stereomicroscope (x 40 magnification) and the average was recorded for statistical analysis. The results were as follows; 1.The mean of apical leakage in group of pure calcium hydroxide ranged 0.102±0.156mm, in Metapaste ranged 0.062±0.069mm, and in Vitapex ranged 0.067±0.072mm. 2.Group of pure calcium hydroxide exhibited more leakage than those of 2manufactured calcium hydroxide preparations, but it was not statistically significant. 3.Group of water-based Mtapaste showed lesser leakage than that of oil-based Vitapex, but it was not statistically significant.

The purposes of this study were to estimate the material properties of the recently developed domestic composite resins for core filling material (Chemical, Dual A, Dual B; Vericom, Korea) and to compare them with other marketed foreign products (CorePaste, Den-Mat, USA; Ti-Core, Essential Dental Systems, USA: Support, SCI-Pharm, USA). Six assessments were made; working time, setting time, depth of polymerization, flexural strength, bonding strength, and marginal leakage. All items were compared to ISO standards. All domestic products satisfied the minimum requirements from ISO standards (working time: above 90 seconds, setting time: within 5 minutes), and showed significantly higher flexural strength than Core Paste. Dual A and B could, especially, reduce the setting time to 60 seconds when cured with 600 mW/㎠ light intensity. All experimental materials showed 6 mm depth of polymerization. Bond strengths of Ti-Core and Dual B materials were significantly higher than the other materials. Furthermore, three domestic products and Ti-Core could reduce the microleakage effectively.

All-in-one adhesives were recently developed for reducing the techique sensitivity and chair time, but lots of concerns were made on bondability, longevity, and microleakage. The object of this study was to evaluate microleakage and marginal quality of all-in-one adhesives using electrochemical method and SEM analysis quantitatively. After making Class V cavities, they were bulk filled with Heliomolar(#A1) after surface treatment with three adhesives: Adper Prompt (Group A), One up Bond F (Group O), Xeno Ⅲ(Group 'X), Electrical con-ductivity(microamphere, ㎂) was checked two times: before and after cavity filling. Percentage of leaky margin was estimated from SEM image (× 1,000). The data were statistically analysed: ANOVA and Paired T test for electrical conductivity, Kruskal-Wallis and Mann-Whitney test for marginal quality, Spearman's rho test for checking of relationship between 2 methods the result were as follows: 1. There was no difference in microleakage between adhesive systems and every specimen showed some of microleakage after filling. 2. Microleakage was reduced about 70% with composite resin filling. 3. Marginal quality was the best in group A, decreasing among groups in the following order: group O, followed by group X. There were significant differences between group A and group X(p=0.015), and between group O and group X(p=0.019) 4. There was no relationship between the microleakage measured by electrochemical method and margin-al quality measured by SEM analysis. Within the results of this study, there was no difference in microleakage groups by electrical conductivity. However, significant difference in margin quality was seen among groups. It was believed teat these dissimilar results might be induced because of their own characteristics. Analysis of microleakage needs various methods for accuracy.
