Emergency medical information center performs role of medical direction about disease consult and pre-hospital emergency handling scheme work to people. Emergency medical information system plays a major role to be decreased mortality and disability of emergency patient by providing information of medical institution especially when emergency patient has appeared. But, various attacks as a hacking have been happened in Emergency medical information system recently. In this paper, we proposed security structure which can protect the system securely by detecting attacks from outside effectively. Intrusion detection was performed using rule based detection technique according to protocol for every packet to detect attack and intrusion was reported to control center if intrusion was detected also. Intrusion detection was performed again using decision tree for packet which intrusion detection was not done. We experimented effectiveness using attacks as TCP-SYN, UDP flooding and ICMP flooding for proposed security structure in this paper.

This paper proposed a versatile algorithm based on a dual-tree complex wavelet transform for intensifying the visual aspect of medical images. First, the decomposition of the input image into a high sub-band and low-sub-band image is done. Further, to improve the resolution of the resulting image, the high sub-band image is interpolated using Lanczos interpolation. Also, contrast enhancement is performed by singular value decomposition (SVD). Finally, the image reconstruction is achieved by using an inverse wavelet transform. Then, the Gaussian filter will improve the visual quality of the image. We have collected images from the hospital and the internet for quantitative and qualitative analysis. These images act as a reference image for comparing the effectiveness of the proposed algorithm with the existing state-of-the-art. We have divided the proposed algorithm into several stages: preprocessing, contrast enhancement, resolution enhancement, and visual quality enhancement. Both analyses show the proposed algorithm's effectiveness compared to existing methods.

Objective: To report a case of a patient with a psychosomatic disorder who complained of hyperventilation and was treated with oriental medical treatments and emotional freedom techniques (EFTs). Methods: The patient was diagnosed as having a psychosomatic disorder through an interview and several psychological tests, such as the house-tree-person (HTP) and the person in the rain (PITR) tests. We treated the patient with oriental medical treatments that included herbal medications, western medications, moxibustion, cupping, and EFT. Results: After the treatments, the clinical symptoms of the patient were improved. Conclusions: Oriental medical treatments and EFT may be effective treatments for psychosomatic disorders.

A total of 362 bile samples from 104 patients with evidence of biliary tract obstruction were submitted for diagnostic cytology from January, 1989 to April, 1991. The patients were classified based on the obstructive cause, and the cytologic results were reviewed. 298 of the specimens were from patients with intrabiliary malignant structure, and 17 were from patients with extrabiliary malignant compression or benign biliary obstruction. Bile cytology was positive for carcinoma in 42 samples from patients with intrabiliary malignant stricture, and the diagnostic sensitivity was 14%. There were no false positive cases. We concluded that the cause of low sensitivity was degenerative change of cell due to prolonged sampling time. What is noteworthy was the high prevalence of Clonorchis sinensis eggs, being detected in 25 patients with intrabiliary malignancy, supporting the association between clonorchiasis and biliary tree malignancy.

This study presents an analysis of healthcare quality indicators using data mining for developing quality improvement strategies. Specifically, important factors influencing the inpatient mortality were identified using a decision tree method for data mining based on 8,405 patients who were discharged from the study hospital during the period of December 1, 2000 and January 31, 2001. Important factors for the inpatient mortality were length of stay, disease classes, discharge departments, and age groups. The optimum range of target group in inpatient healthcare quality indicators were identified from the gains chart. In addition, a decision support system was developed to analyze and monitor trends of quality indicators using Visual Basic 6.0. Guidelines and tutorial for quality improvement activities were also included in the system. In the future, other quality indicators should be analyze to effectively support a hospital-wide continuous quality improvement (CQI) activity and the decision support system should be well integrated with the hospital OCS (Order Communication System) to support concurrent review.

In the growing data saturated world, the question of "whether data can be used" has shifted to "can it be utilized effectively?" More data is being generated and utilized than ever before. As the collection of data increases, data mining techniques also must become more and more accurate. Thus, to ensure this data is effectively utilized, the analysis of the data must be efficient. Interpretation of results from the analysis of the data set presented, have their own on the basis it is possible to obtain the desired data. In the data mining method a decision tree, clustering, there is such a relationship has not yet been fully developed algorithm actually still impact of various factors. In this experiment, the classification method of data mining techniques is used with easy decision tree. Also, it is used special technology of one R and J48 classification technique in the decision tree. After selecting a rule that a small error in the "one rule" in one R classification, to create one of the rules of the prediction data, it is simple and accurate classification algorithm. To create a rule for the prediction, we make up a frequency table of each prediction of the goal. This is then displayed by creating rules with one R, state-of-the-art, classification algorithm while creating a simple rule to be interpreted by the researcher. While the following can be correctly classified the pattern specified in the classification J48, using the concept of a simple decision tree information theory for configuring information theory. To compare the one R algorithm, it can be analyzed error rate and accuracy. One R and J48 are generally frequently used two classifications${\ldots}$

소나무재선충에 자연 감염된 소나무와 잣나무로부터 소나무재선충을 분리하여 수종 간 분리율과 수종 내 부위별 밀도 등을 비교하고, 분리한 선충을 소나무 묘목에 접종하여 묘목 내에서의 이동을 알고자 하였다. 2006년, 소나무재선충에 감염되어 말라죽었거나 죽어가고 있는 소나무와 잣나무로부터 소나무재선충을 분리한 결과, 소나무재선충은 두 수종 모두에서 높은 밀도로 분리되어 수종 간에 차이를 보이지 않았다. 또한, 각 수종의 변재부 위에서만 분리되었으며, 분리한 조직을 채취한 줄기의 높이에 따른 분리율에는 차이가 없었다. 즉, 말라죽은 나무의 주간은 모든 조직이 소나무재선충에 감염되어 있었다. 소나무 묘목에의 접종실험을 통하여 감염목 내 이동을 조사한 결과, 감염초기에 소나무 조직 내로 침입한 소나무재선충은 증식에 앞서 감염목 내에서 빠르게 이동하여 퍼지기 시작하였고, 그 이후에 왕성한 증식활동을 하였으며, 이 시기가 바로 소나무 시들음병의 외부병징이 나타나는 시기가 일치함을 알 수 있었다. 소나무재선충의 이동경로를 조사하기 위해 접종한 소나무 줄기횡단면을 현미경으로 관찰하고, 또 높이별로 선충을 분리하여 조직 내 선충의 분포를 관찰한 결과, 줄기의 피층에 있는 수지도를 통해 접종부위로부터 다른 부위로 빠르게 이동을 하고, 시간이 경과하면서 조직 내에서 증식한 소나무재선충은 피층의 수지도뿐만 아니라 목질부수지도나 가도관까지 분포하여 감염목내 전 부위에 걸쳐 고루 분포하였다. 그러나 수조직에서는 분리할 수 없었다. 소나무재선충 분리밀도가 높았던 묘목은 뿌리의 발달이 불량하거나, 목질부 변색균에 감염된 것들이었으며, 비교적 튼튼한 외양을 한 묘목에서는 선충의 분리밀도가 낮았다.
