보안위협 모니터링을 위한 AI 데이터셋 구성방안 연구

한상현, 조인준 배재대학교 공학연구소 2021 공학논문집 Vol.23 No.1

Cyber-attacks are evolving into a form of a long-term continuous attack by forming a dense group. However, there are cases of being defenseless against hacking attacks due to the lack of information on vulnerabilities exposed to security threats. In addition, organizations and companies with limited assets and response capabilities are often unable to take action due to the lack of measures to respond to such attacks. To solve this problem, we create a shared dataset by collecting various vulnerability information that has been disclosed, and after learning AI, we intend to present information on security vulnerabilities and effective detection and response methods for hacking attacks targeting vulnerabilities. 사이버 공격은 치밀하게 집단을 구성하여 장기간 지속적인 공격을 하는 형태로 진화하고 있다. 하지만 보안위협에 노출된 취약점들에 대한 정보 부재로 해킹공격에 무방비로 당하는 사례도 발생하고 있다. 또한 자산 및 대응역량이 제한된 기관 및 기업들은 이러한 공격에 대응할 수 있는 방안 부재로 조치를 할 수 없는 경우가 상당히 많다. 이러한 문제점을 해결하기 위해 공개되어있는 각종 취약점 정보들을 모아 공유 데이터셋을 만들어 AI 학습 후 보안취약점에 대한 정보와 취약점을 노린 해킹공격에 대한 효과적인 탐지와 대응하는 방안을 제시하고자 한다.

Intercellular adhesion molecule-1 (ICAM-1) is a glycoprotein serving as ligands for leukocyte intergrin receptors, i.e. LFA-1, MAC-l. It has been suggested that the expression of ICAM-1 and the levels of circulating ICAM-1 were increased in several malignancies. We measured serum ICAM-1 by ELISA in patients with stomach cancer (n=25), acute lymphoblastic leukemia (n=7), non-Hodgkin's lymphoma (n=14), and metastasis of unknown origin (n=5). Serum levels of circulating ICAM-1 in all malignancies were significantly higer than in normal controls. And serum level of ICAM-1 in stomach cancer ptients having metastatic disease was higher than in patients with localized disease (p=0.027). These results suggest that elevated serum ICAM-1 is a rather common feature for malignancies, not unique for certain types of cancer such as malignant melanoma. It remains to be clalified whether marked increase of serum ICAM-1 in metastatic stomach cancers simply reflect tumor burden or this molecule plays a role in progression in stomach cancer.

In an existing rice paddy, we established an subsuface drainage and a auxilialy drainage at proper intervals to accelerate the underground drainage. In the process of building up a rotation field. we studied the little physical change of the soil over 24 months. Various tests were conducted (a. Munsell soil color test b. Constant head permeability and permeability test c. Examination of aeration, degree of hardness, waterproof quality d. Shear resistance and friction resistance test e. Moisture content and specific gravity test and f. Measurement of moisture content and void ratio by nuclear density meter). These tests were conducted by many people on soil from each plot. Results of the study are as follows. Paddy fields of Korea have a particularity different from the European countries and America that drain the excess soil water from the shallow surface soil layer. The facing problems on the planning and designing of subsurface drainage are determining the spacing of main subsurface drainage system, combination design of main and auxiliary subsuface drainage system and the structure of subsuface drainage ditch. The structure of subsurface drainage ditch consist of drainage pipe and filling materials such as rice bran and pebbles. The width of subsuface drainage ditch is 20cm in case of trencher operation and 30cm in case of back hoe excavation. The advisable depth of subsuface drainage ditch is below 50cm. In an subsuface drainage plot, the supporting force and the plate sinking volume increased, But the moisture content and specific gravity test, according to the tests had a tendency to decrease. Similarly, moisture content and void ratio as indicated by the nuclear density meter generally showed a tendency to decrease. In addition, aeration, degree of hardness, and the waterproof aggregates percent of soil generally incleased in an subsuface drainage plot. From the above results, we found that when an subsuface drainage was establshed in a silty rice paddy having poor permeability, the physical qualities of that rice paddy became those of a dry field.

This study was conducted to investigate the difference of general feature and ginsenoside content of 6 years old ginseng rooot among different grade of roots. Total weight of a 1st grade-6 years old ginseng root was 115.1g and weight, length, diameter and specific gravity of main root were 64.68g, 8.39cm, 3.31cm and 0.96, respectively. Main root of 1st grade ginseng root was larger in size and specific gravity and more heavy than that of 2nd or 3rd grade of the roots. Though crude saponin contents were not so different among the different grade of roots, but ginsenoside Rbl, Rgl and Re content were higher in 1st grade of root than that of 2nd or 3rd grade of root. Those ginsenosides were located mainly in periderm and cortex.

Purpose : The purpose of this study was to evaluate the effect of nutritional support with enteral liquid supplement in cancer patients receving chemotherapy for possible benefit in nutritional, immunologic and golbal function of patients. Patients and Methods : From October 1995 to February 1997, 30 advanced cancer patients receving chemotherapy were divided two roups. The Nycare group, in addition to normal diet, Nucare^R enteral supplement was given for 1week right after chemotherapy for the duration of 2 chemotherapy cycles. Control group received only normal diet without parenteral fluid supplement for 2 chemotherapy cycles. Results : Median ages were 53 end 56 years for Nucare group and Contrl group respectively. Performance scores was less than 2 by ECOG scale. All patients were stage Ⅲ or Ⅳ. The physical parameters, such as weight, arm muscle circumference(AMC) and triceps skin fold(TSF) were decreased in both groups after 2 cycles of anticancer therapy. but it was less severe in Nucare group(p<0.05). Serum transferrin was maintained in mild deficit state in Nucare group, whereas it aggravated form mild to moderate deficit in Control group(p<0.05). Serum albumin level increased in Nucare group without statistical significance. but it decreased from normal to mild deficit in Control group. Serum total protein did not change significantly in Nucare group. but in Control group, serum total protein was decreased from 7.24±0.9 to 6.52±0.5(P<0.05). Total lymphocyte count did not change significantly in both groups. Conclusion : This study shows that the nutritional support with Nucare^R was effective in the prevention of nutritional deficit status in patients receving a nticancer chemotherapy.

Jo,Man-Hyun,Ham,In-Ki,Park,Sang-Kyu,Seo,Gwan-Seok,Han,Gyu-Heung,Woo,In-Shik 한국자원식물학회 2003 Plant Resources Vol.6 No.2

Allium wakegi Araki was grown at plant spacings of 5, 10, 15, and 20 cm to determine the effect of planting density on the growth and yield. Allium wakegi Araki plants grown at the 5 cm plant spacing had the lowest bulb diameter and bulb weight, while plants at the lowest density (20 cm spacing) had the highest bulb diameter, bulb number, bulb weight and fresh weight. In general, plants grown at narrower spacings produced significantly smaller bulb diameter and bulb weight, but resulted in the highest yields and plants per hectare and lower fresh weights per plant.

Jo,Man-Hyun,Ham,In-ki,Park,Sang-kyu,Seo,Gwan-Seok,Han,Gyu-Heung,Woo,In-Shik 한국자원식물학회 2003 Plant Resources Vol.6 No.2

This study was conducted to develop the clonal propagation technique through in vitro culture using basal stem explants in Phalaenopsis hybrid grown in vitro. The highest frequency of protocorm-like body (PLB) formation was obtained when basal stem explants were cultured on VW medium containing 30g/L sucrose, 500 mg/L activated charcoal, 150 ml/L coconut water, 1 mg/L NAA, 5 mg/L 2iP and 2.5g/L gel rite. PLBs transferred to Hyponex medium were regenerated to plantlets. Plantlets transferred to plastic pots containing spagnum moss were developed and successfully acclimatized under greenhouse. The flower was bloomingly opened in plants regenerated from basal stem explants. The flower was not different from both mother plant and plant induced through clonal propagation of Phalaenopsis hybrid.

서비스 상황에서 구매 행위의도에 영향을 미치는 확장된 모형에 대한 실증분석

이상현,유창조,장문성 한국방송광고공사 2007 광고연구 Vol.0 No.74

본 연구는 서비스 구매상황에서의 고객행위의도에 영향을 미치는 변수들을 다양한 각도에서 검증하였다. 이를 위하여 본 연구는 기존의 행위예측모델로서 설명할 수 없었던 확장된 규범변수를 소개하고 서비스 구매행위의도와의 인과관계를 분석하였다. 기존의 구매행위 연구들은 제품구매와 관련된 행위이거나, 자신만의 관심사와 관련한 행위에 국한되어왔고 그에 따라 개인의 태도와 주관적 규범이 가장 중요한 설명요인으로 제시되어왔다. 그러나 대부분의 서비스 상황에서 소비자들은 자신의 주관적 규범뿐만 아니라 서비스 시스템내의 다른 구성원(다른 참여 소비자)을 의식할 수 있고 이러한 의식은 행위의도에 영향을 미칠 수도 있다. 본 연구는 이러한 서비스 참여고객 반응규범의 개념을 소개하고 이 연구단위가 소비자의 서비스 구매에 미치는 영향을 분석하였다. 연구결과, 서비스 구매의도에 영향을 미치는 요인으로 소비자의 서비스에 대한 태도와 주관적 규범뿐만 아니라 시스템내의 다른 구성원에 대한 인식 즉, 서비스 참여고객 반응규범 또한 중요한 영향 요인으로 검증되었다. 아울러 태도와 주관적 규범과 마찬가지로 참여고객 반응규범 또한 신념과 의도를 매개하는 것으로 나타났다. 본 연구의 주요 시사점은 서비스 상황에서 서비스 참여고객 반응규범이라는 새로운 연구단위를 통하여 기존의 태도모형을 확장시켰다는 점이다. This study examines crucial factors influencing consumer’s behavioral intension in a service purchasing situation. It introduces an extended norm construct that could not be explained in previous behavioral intention models. Furthermore, it investigates the association between the extended norm construct and behavioral intention along with other constructs (attitude and subjective norm) in the theory of reasoned action model. Past research has shown that attitude and subjective norm are the most important factor to explain behavioral intention. It is because that past research has been limited to a product purchase behavior and/or personal interesting behavior. This study, however, suggests that customers may aware of other people, mostly other customers who are participated in a service system when they intent to purchase a service. As a result, service participation customer norm, the consciousness of other customers in the service system, along with attitude and subjective norm, is another important factor to influence behavioral intention. Furthermore, service participation customer norm was shown as a mediator in the relationship between the belief structure and behavioral intention. Contribution of this study is to expand the theory of the reasoned action model through the finding a new construct, service participation customer norm to explain a behavioral intention in the service encounter.

중독한 추체로 증상을 보인 cyclosporine에 의한 뇌증 1예

강정현,곽승근,신현영,김성은,이정호,이정찬,곽상혁,윤환중,조덕연,김삼용,김제,송창준 충남대학교 의과대학 지역사회의학연구소 2000 충남의대잡지 Vol.27 No.1

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.
