사이버 공격이 더욱 지능화됨에 따라 기존의 침입 탐지 시스템(Intrusion Detection System)은 기존의 저장된 패턴에서 벗어난 지능형 공격을 탐지하기에 적절하지 않다. 딥러닝(Deep Learning) 기반 침입 탐지는 새로운 탐지 규칙을 생성하는데 적절하다. 그 이유는 딥러닝은 데이터 학습을 통해 새로운 침입 규칙을 자체적으로 생성하기 때문이다. 침입 탐지 시스템 데이터 세트는 가장 널리 사용되는 KDD99 데이터와 LID-DS(Leipzig Intrusion Detection-Data Set)를 사용했다. 본 논문에서는 1차원 벡터를 이미지로 변환하고 CNN(Convolutional Neural Network)을 적용하여 두 데이터 세트에 대한 성능을 실험했다. 평가를 위해 Accuracy, Precision, Recall 및 F1-Score 지표를 측정했다. 그 결과 LID-DS 데이터 세트의 Accuracy가 KDD99 데이터 세트의 Accuracy 보다 약 8% 높은 것을 확인했다. 또한, 1차원 벡터에 대한 데이터를 Kibana를 사용하여 데이터를 시각화하여 대용량 데이터를 한눈에 보기 어려운 단점을 해결하는 방법을 제안한다.

We described the effects of antioxidant activity on the extracts of tissue and callus formation by Cirsium setidens Nakai. The callus culture were induced from leaf tissue of Cirsium setidens in both MS and B5 medium with IAA or/and kinetin (0∼5.0 ㎎/ℓ). As medium for callus culture induced from Cirsium setidens, B5 medium showed better condition than MS media. MS medium brought to decrease callus differentiation after formation, on the other hand B5 medium induced to accelerate callus differentiation. Among phytohormones is required 0.5 ㎎/ℓ of IAA and between 2.0 ㎎/ℓ and 1.0 ㎎/ℓ of Kinetin for formation of callus. In order to extract functional material from natural leaf and callus tissue of Cirsium setidens used distilled water and 75% ethanol as solvent and those extract used to determine antioxidant activity as alpha-diphenyl-2-picryl-hydrozyl (DPPH) radicals scavenging effect and TBA(thiobarbituric acid) activity. In result, the effect of DPPH and TBA had high activity more natural leaf extract than callus tissue and 75% ethanol was solvent better than distilled water. The 75% ethanol extract of natural leaf showed an excellent antioxidant activity because that particularly had highest concentration of vitamin C and total phenol among those extracts

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

Exercise-induced anaphylaxis(EIA) is a medical emergency in that it derives from a physical allergy. We reported a case of food-independent EIA based on history and laboratory data. A 40-year-old male patient was presented with generalized urticaria, angioedema, and syncope after jogging. He had suffered from allergic rhinitis for 25 years. Increased level of serum tryptase was noted. Mast cell activation might be suggested in the pathophysiologic mechanism of EIA. (J Asthma Allergy Clin Immunol 24 : 152-5, 2004)

$20^{\circ}C$에서 15일 동안 저장기간별 사과의 변화를 살펴본 결과는 다음과 같다. 사과의 중량과 수분은 저장기간 경과에 따라 점차적으로 감소하는 결과를 보였으며, 사과의 저장 중 가용성 고형물 함량은 저장 4일차까지 최고치로 증가하였다가 서서히 낮아지는 경향을 나타냈다. 사과의 저장 중 유기산 산도는 저장 5일차에 급격히 감소하다가 완만히 감소하였으며, pH는 저장기간에 따라 완만히 증가하는 경향을 나타내었다. 저장 중 사과 껍질의 색상을 측정한 결과, L값은 저장기간에 따라 서서히 증가하였으며, a값은 저장 3일까지 감소하였고, 저장 5일에 증가되었다가 그 이후 점진적으로 감소하였다. b값은 저장 6일에 최저치를 보인 후 서서히 증가하는 경향을 보였다. 사과의 조직감을 측정한 결과, 저장기간이 증가됨에 따라 사과의 경도는 전반적으로 감소하였다. 저장 기간에 따른 사과의 총 페놀과 총 플라보노이드 함량을 측정한 결과, 총 페놀 함량은 저장 기간이 길어질수록 감소하는 경향이 나타났으며, 저장 3일차에서 저장 4일차에 큰 폭 감소하였다. 총 플라보노이드의 변화 결과, 1일차에 비교적 크게 감소하였고, 실험 7일차에서 8일차 사이에 급격히 감소하였다. 저장 기간에 따른 사과의 DPPH 전자공여능 측정결과, 저장기간이 증가할수록 DPPH 전자공여능은 감소하였으며, Vit. C 함량의 경우 저장 기간이 길어질수록 감소하였는데, 특히 저장 4일차에 비교적 크게 감소하였다. 사과의 관능평가 수행 결과, 저장기간이 경과함에 따라 외관의 좋은 정도는 0일차에 6.75에서 15일차 2.83으로 크게 감소하였으며, 신맛의 좋은 정도는 저장 기간에 따라 유의적인 차이를 보이지 않았으나, 전반적으로 감소하는 경향이었다. 단맛의 좋은 정도와 아삭함의 좋은 정도에서는 0일차에 각 6.25, 5.33으로 가장 높았으며, 15일차에 각 3.92, 2.83으로 유의적으로 감소하였다. 종합적인 기호도에서는 7일차와 8일차 사이에 5.00에서 3.50으로 비교적 큰 폭 감소하였으며, 15일차에 2.00으로 저장 기간에 지남에 따라 유의적으로 감소하였다. 이상의 실험결과, 사과 저장 시 3~4일차에 유의적인 차이를 보였으며, 저장 8일 이후에는 모든 항목에 있어 측정감이 크게 변화하는 경향을 나타내었다. 따라서 $0{\sim}1^{\circ}C$에서 장기 저장한 사과를 $20^{\circ}C$ 전후에서 저장 및 판매할 경우, 최고의 품질을 위해서는 3일 내에 판매할 것을 권장하며, 8일 이내에 재고를 소진할 수 있도록 유통 기간을 조정하는 것이 바람직할 것으로 사료된다. This study was performed in order to compare the changes in Korean apples' qualities and antioxidant activity when stored at room temperature, $20^{\circ}C$, for fifteen days. The results showed that the weight, moisture content, soluble solid content, acidity, and hardness levels decreased as the storage period increased. However, pH and color value L increased as the storage period increased. Total phenol contents, total flavonoids contents, DPPH free radical scavenging activity, and vit. C contents of apples significantly decreased with increased storage period. Sensory parameters, such as appearance, sweetness, sourness, crunchiness, and overall acceptability of apples, also decreased as the storage period increased. Based on these results, if, the apple are being stored around $20^{\circ}C$, then, to have the highest quality, the apples should be sold within three days, We also suggested that it is desirable not to store the apples fore more than eight days.

There have been many trials of clinical efficacy of multicomponent and single component treatments for irritable bowel syndrome(IBS). We reviewed effects of non phamacological treatments in the IBS. Though the efficacy of multi-component approaches was unclear, several results suggest that cognitive behavioral therapy was effective in improving gastrointestinal symptoms of IBS. As a single component, cognitive therapy and relaxation with or without biofeedback could improve the symptoms and psychological health of IBS patients. Yoga, meditation, self-help information and hypnotherapy could be applicable to IBS.

Acute torsion of the ovary and ovarian mass is a recognized surgical emergency, but rarely has the diagnosis been made preoperatively on the basis of imaging studies. The sonographic findings in 14 cases of surgically proven torsion of the ovary and ovarian mass are described. Mostly cystic ovarian mass, engorged vessel, dilated uterine tube, beak-like echo(torsion site), smooth mass wall thickening an free-fluid collection in cul-de-sac are described. More significant in terms of specificity were the demonstration in 6 cases(42.9%) of the smooth mass wall thickening and in 8 cases(57.1%) of a free fluid in the cul-de-sac. We report the sonographic findings of ovary and ovarian mass torsion that may suggest the preoperative diagnosis of this condition.

이재영,윤성호,서유진,최정희,서창희,남동호,김윤근,민경업,박해심 대한천식 및 알레르기학회 2004 천식 및 알레르기 Vol.24 No.1

Background : The common whelk (Buccinum undatum) is one of the largest and most common snails in the North Atlantic. In Korea and Japan, common whelk is a popular eatable shellfish. Although shellfish has been known as the one of the most common causes of food allergy, there has been no published report on allergenecity and clinical significance of this sea snail. In this study, we determined the sensitization rate to common whelk and its relationship with other food allergens in allergy patients. Method : We carried out the skin prick test (SPT) with commonly consumed food stuffs in Korea including common whelk in 1700 patients over 1 year. The specific IgE to common whelk were detected by enzyme-linked immunosorbent assay (ELISA). ELISA inhibition test using sensitized sera was conducted. Results : SPT to common whelk was positive (≥2+) in 83 (4.9%) patients studied. Twenty-four (38.7%) of 62 SPT-positive patients had high serum specific IgE to common whelk. ELISA inhibition test showed significant inhibitions by abalone as well as by common whelk and, minimal inhibition were noted by shrimp. Significant correlation was also noted in specific IgE levels between common whelk and abalone (r=0.58, F<.05). Conclusion : IgE-sensitization rate to common whelk was 4.9% in allergy patients. Further stuides are needed to evaluate the clinical significance of sensitized patients to common whelk, and to confirm a cross reactivity with abalone. (J Asthma Allergy Immunol 24 : 77-84, 2004)
