To diagnose the typhoid fever rapidly and accurately in clinically suspected patients, the levels of IgG subclass antibody were measured by enzyme-linked immunosorbent assay(ELISA). With symptom, blood culture and agglutination test, tested persons were categorized into 6 groups as typhoid fever, FUO, paratyphi A or B, other bacterial infctions, cancers, and control. ELISA was performed on the polyvinyl chloride plates coated with killed whole cell($10^8\;cell/ml$) of S. typhi 0901W by poly-L-lysine applied as binding substance (and polyvinyl chloride as solid phase). The distribution of the level of IgG subclass antibodies in each group was analyzed and compared with other groups. The results obtained were summarized as follow: 1. The optimal dilution of the sera from patients with typhoid fever was 1:160, and those of the sheep anti-human IgG subclass and the peroxidase conjugated rabbit anti-sheep IgG were 1:4000 and 1:5000, respectively. 2. The absorbance levels of IgG subclass in the sera of typhoid fever patients were as follows; a) IgG1 value is $0.439{\pm}0.110$ b) IgG2 value is $0.416{\pm}0.165$ c) IgG3 value is $0.449{\pm}0.145$ d) IgG4 value is $0.525{\pm}0.154$ IgG subclass levels in the sera of typhoid patients were much higher than in control group and patient with paratyphi A or B as well as other infectious diseases. The sensitivity and the specificity in differential diagnosis of typhoid fever and other febrile diseases were 92% and 79% in the assay of IgG1 respectively, whereas those in the assay of IgG2 were 97% and 72%, respectively (above absorbance 0.3). 3. The absorbance levels of IgG subclass in the serial sera of typhiod fever patients tend to decrease to the level of absorbance 0.3 in 10 months from the onset of illness. 4. The order of absorbance levels of IgG subclass in the serum of each group were typhoid fever, paratyphi A or B, other infectious diseases, control and cancer. 5. For the serodiagnosis of typhoid fever against other febrile diseases, the sensitivity and the specificity in the assay of IgG2 activity were 76% and 93% in absorbance 0.4, respectively. 6. In the distribution of the level of each IgG subclass in the sera of FUO patients which were suspected of typhoid fever, the positive rate was ranged from 36% to 82%. This suggest that more than 50% of FUO patients are caused by S. typhi.

Combination treatment of antiplatelet drugs containing aspirin and clopidogrel reduces systemic ischemic events after percutaneous coronary intervention (PCI) in high risk patients. However, this combination treatment of antiplatelet drugs is associated with increased risk of nonfatal and fatal bleeding. Diffuse alveolar hemorrhage after PCI is a rare complication that has been mostly reported in associa-tion with glycoprotein IIb/IIIa inhibitors. We report the case of a 62-year-old man who presented with ST elevation myocardial infarction and suffered a diffuse alveolar hemorrhage after clopidogrel use following primary PCI.

궤도회로는 열차의 유무를 검지하는 장치로, 레일을 전기회로로 사용해 회로의 단락 유무를 이용해 열차가 폐색 구간을 점유하고 있는지 검지한다. 궤도회로는 신호기 및 연동장치와 같은 신호기기를 제어할 때 사용될 수 있으며, 궤도회로 중 가청주파수를 사용해 열차를 검지하는 궤도회로는 Audio Frequency(AF) 궤도회로라고 지칭된다. AF 궤도회로는 열차를 제어하는 정보를 코드화해 열차로 전송하며, 열차는 해당 정보를 수신하고 필요시 안전한 열차운행을 위한 감속 및 정지 동작을 수행한다. 최근 철도차량은 스위칭을 사용해 전력을 공급하는 다양한 전기 회로를 사용하며, 고조파가 귀선전류를 통해 AF 궤도회로에 영향을 미친다. 따라서, AF 궤도회로가 열차의 위치를 감지하지 못하는 문제가 존재한다. 본 논문은 고조파로 인한 부정여자를 최소화하기 위해 궤도회로 수신 모듈에 기계학습 알고리즘을 적용했고, 기존 방식과의 성능 비교를 통해 제안하는 방식이 우수함을 입증했다. A track circuit is a device that detects the presence of a train. The track circuit uses the rail as its electric circuit and detects if the train is occupying a fixed block or not, using the state of a circuit. The track circuit provides basic control information for the railway signal system. A track circuit that uses audio frequency to detect trains is called an Audio Frequency (AF) track circuit. The AF track circuit transmits encoded train control information to the train. The train receives information and performs safety operation based on the information. Modern electric rolling stock uses electric circuits with switching, which generates harmonics, to supply power. The harmonics of the rolling stock can interrupt the AF track circuit. Therefore, the AF track circuit cannot detect the train position. In this paper, we applied a machine learning algorithm to minimize interruption of the SMPS harmonics of the AF track circuit. Also, we compared performance of the proposed system and the conventional system and showed the superior performance of the proposed system

Understanding the gene flow from genetically modified (GM) crops to conventional crops is important to prevent and mitigate seed contamination caused by pollen-mediated gene flow. We conducted a field test to investigate the gene flow from diamondback moth resistant GM cabbage (Brassica oleracea var. capitata) containing cry1Ac1 gene, to a non-GM control line AD126. GM and non-GM cabbage plants were cultivated in the field and pollinated using Bombus terrestris under the nets during the flowering periods. After seeds were collected from non-GM plants, hybrids between them and the GM cabbages were screened by multiplex PCR targeting cry1Ac1 gene. Out of 878 germinated seedlings, 168 hybrids were found and the average gene flow frequency was 19.7%. Because cabbage is mainly pollinated by insect pollinators, large-scale field tests are needed to study gene flow of GM cabbage.

Endoscopic retrograde cholangiopancreatography (ERCP)-related iatrogenic perforations are identified when gas or luminal contents exit the gastrointestinal tract during ERCP. Although perforations are rare, mortality is high; prompt diagnosis and appropriate management are essential. A multidisciplinary approach is required. The vast majority of such patients can be safely managed medically and endoscopically but must be carefully selected. Endoscopic closure can be considered, depending on the type of perforation. In patients who are deteriorating or whose iatrogenic perforations are not securely closed endoscopically, surgery is mandatory. (Korean J Med 2021;96:318-327)

This study is aimed to find out whether there is difference in the physiological change of a human body according to the illumination and color of interior space or not and to specify the effect of the condition of illumination and color, respectively on the attention. In order to do so, White and Green were selected for colors and 4,000k, 5,000k, and 6000k were done for color temperature, and then attention was identified. Examining the results, the more color temperature increased, the more attention improved (P < 0.05), and in the case of EEG, α wave decreased while performing the task of attention (P < 0.01), and β wave decreased more in Green than White in color condition, and it increased more in 4,000k than 5,000k and 6,000k (p < 0.05) in color temperature condition. To sum up, color condition didn t contribute to the attention much, in the case of color temperature, when it is 6,000k, it is judged that it helped to improve attention. It is considered that relaxation contributed to improving attention, as β wave and sympathetic nerve decreased in 6,000k (p < 0.05). It is judged that the relaxation of tensions which happened due to a beta wave and the reduction of sympathetic nervous system activity in 6,000k, a condition of high color temperature, contributed to the improvement of concentration. In further researches, it is intended that a test will be conducted for the subjects of different ages, and the correlation between color temperature and color stimulation and the influence of them on human body would be observed in subdivided, various test conditions through various color temperature and color stimulation.
