Purpose: The purpose of this study is to set up an anomaly detection criteria for sensor data coming from a motorcycle. Methods: Five sensor values for accelerator pedal, engine rpm, transmission rpm, gear and speed are obtained every 0.02 second from a motorcycle. Exploratory data analysis is used to find any pattern in the data. Traditional process control methods such as X control chart and time series models are fitted to find any anomaly behavior in the data. Finally unsupervised learning algorithm such as k-means clustering is used to find any anomaly spot in the sensor data. Results: According to exploratory data analysis, the distribution of accelerator pedal sensor values is very much skewed to the left. The motorcycle seemed to have been driven in a city at speed less than 45 kilometers per hour. Traditional process control charts such as X control chart fail due to severe autocorrelation in each sensor data. However, ARIMA model found three abnormal points where they are beyond 2 sigma limits in the control chart. We applied a copula based Markov chain to perform statistical process control for correlated observations. Copula based Markov model found anomaly behavior in the similar places as ARIMA model. In an unsupervised learning algorithm, large sensor values get subdivided into two, three, and four disjoint regions. So extreme sensor values are the ones that need to be tracked down for any sign of anomaly behavior in the sensor values. Conclusion: Exploratory data analysis is useful to find any pattern in the sensor data. Process control chart using ARIMA and Joe's copula based Markov model also give warnings near similar places in the data. Unsupervised learning algorithm shows us that the extreme sensor values are the ones that need to be tracked down for any sign of anomaly behavior.

이탈리아의 전진이탈리아, 북부동맹, 오성운동당의 유럽회의주의는 이탈리아의 국내정치의 내부적 대립과 경쟁의 결과로 이해할 수 있다. 이들 세 정당들이 취한 유럽회의주의적 입장은 이탈리아 정치지형변화의 특수성에 기인하여 제한적으로 표출되었다. 이탈리아의 정부형성은 대단히 포괄적인 거대 연맹(coalision)의 형태로 이루어져 왔고, 각기 다른시대에 정부의 책임을 공유하였다. 이는 정당들의 유럽회의적인 실질적인 표현에 제한성으로 작용하였음은 분명해 보인다. 또한 전후 이탈리아의 정치 체계속에서 등장한 정당들은 극심한 분열과 대립의 구도속에서 반대정치세력에 대한 견제에 집중한 정치전략을 필요로 했다. 이들 정당은 당의 창설 초기부터 유럽회의적 사안을 주요한 정치적 이슈로 부각하지 않았다. 오히려, 초기집권동안 전진이탈리아의 정치기조는 친유럽적인 성향을 띤 것이었다. 정당은 긴축재정과 이민급증의 경제, 사회문제에 직면하여 유럽회의적으로 전환한 공공담론을 인식하면서, 선거지지를 확보하기 위한 포괄적 정치전략으로 반유럽통합 담론을 부각시켰다. 같은 맥락으로 북부동맹의 초반 정치기조는 연방주의 형성을 위한 유럽통합에 동조하는 입장이었지만, 정당의 주변화와 정치지지 하락에 직면하여 정당 회생을 위한 대안으로 유럽회의적 정치 입장으로의 전향을 시도하였다. 오성운동당 역시, 반유럽적 사안은 국내의 정치적 대립속에서 정당의 합리성을 강화하기 위한 전략으로 채택된 것이었다. 한편, 자국의 경제이익과 정체성 보존 및 사회질서를 위해 타인종을 배격하고 반유럽을 주장하는 우파 포퓰리즘 정당과 극우정당이 대중의 공감을 획득하고 이탈리아 의회내의 입지가 강화되는 현상은 이탈리아의 정당체계에서 유럽회의주의의 점증 변수로 작용될 여지로 이해된다. 이에 따라 이탈리아 유럽회의주의 전당의 정치전략적 변화는 향후 유럽통합의 방향성에 따라 매우 유동적으로 전개될 가능성이 엿보이며, 이에 대한 다양한 연구적 질문과 분석이 이루어져야 할 것으로 사료된다.

Purpose: This aim of this study is to analyze the dosimetric difference between intensity-modulated radiation therapy (IMRT) using 3 or 5 beams and MSF in the radiotherapy of the left breast. Materials and Methods: We performed a comparative analysis of two radiotherapy modalities that can achieve improved dose homogeneity. First is the multistatic fields technique that simultaneously uses both major and minor irradiation fields. The other is IMRT, which employs 3 or 5 beams using a fixed multileaf collimator. We designed treatment plans for 16 early left breast cancer patients who had taken breast conservation surgery and radiotherapy, and analyzed them from a dosimetric standpoint. Results: For the mean values of $V_{95}$ and dose homogeneity index, no statistically significant difference was observed among the three therapies. Extreme hot spots receiving over 110% of the prescribed dose were not found in any of the three methods. A Tukey test performed on IMRT showed a significantly larger increase in exposure dose to the ipsilateral lung and heart than multistatic fields technique (MSF) in the low-dose area, but in the high-dose area, MSF showed a slight increase. Conclusion: In order to improve dose homogeneity, the application of MSF, which can be easily planned and applied more widely, is considered an optimal alternative to IMRT for radiotherapy of early left breast cancer.

This stydy investigates H-shaped houses in 1930s and examines the characters and meanigs of Kim, Jong-Ryang's H-shaped houses as a new trial to urban Hanok of those days. He, who was concerned about the housing problem of Seoul, made an attempt to make various types of dwellings. Among them, this study focuses on Japanese-Korean Style H-shaped houses in Samcheong-dong. As the alternative housing type against other urban Hanok of Seoul in 1930s, the H-shaped houses of Kim, Jong Ryang had characters as follows : 1) H-shaped houses has two special characters. First, the whole space of a single house can be divided into a left region and a right region. Second, it can be divided to a front region and a rear region. In his H-shaped houses, the left/right division was expressed as folding of space-layers in parallel with urban streets. The front/rear division was used as classification of main-living space and sub-living space. 2) KJR's H-shaped Japanese-Korean Style houses were proved to be designed as urban housing against the extreme housing shortage of Seoul in 1930s. 3) His houses however were not accepted broadly as a urban house type because the construction cost of those was higher than an average and the element of Japanese style house was not adapted to Korea. Kim, Jong-Ryang's trial is valuable because it was the rare case of realization of many discourses as defects of existing house type. With more rigorous investigations on KJR's experiment in modern house type, we could understand the housing condition of Seoul in 1930s and modern urban houses more than before.

We report a case of neurolymphomatosis of lumbosacral plexus. A 63-year-old man, who had no past history except for diabetes mellitus, complained of severe pain and weakness on left lower extremity. Idiopathic lumbosacral plexopathy was diagnosed by electromyography. There were no abnormal findings except for FDG-PET/CT and MRI. They showed high uptake and thickening lesion in sciatic nerve and sacral plexus. However, about 7 months later, mass like lesion in left thigh was detected by FDG-PET/CT and MRI. Also, multiple hypermetabolic lesions were found in brain. Through brain biopsy, diffuse large B-cell lymphoma was confirmed. When a patient with idiopathic lumbosacral plexopathy complains of severe pain, it is necessary to consider FDG-PET/CT and MRI to differentiate neurolymphomatosis, even in patients who have no past history of lymphoma before. Especially, if FDG-PET/CT and MRI show sciatic and/or lumbosacral plexus lesion, neurolymphomatosis of lumbosacral plexus should be considered.

Purpose: We aim to research the difference of abdominal temperature in dysmenorrhea patients comparing with that of normal person. Metholds: We selected the 49 dismenorrhea patients as study group and 54 normal persons as control group, excluding the patients who have dermatitis, ared over 70 or under 10. and have extreme obesity. We compared the 4 points(Rt and Lt Gimun(LR14) and Guirae(ST29)) in thd abdomen of both group, check the temperature of those points with DITI(Dorex, DTI-16UTI) to compare the temperature difference with each other. For statistics, we use independent T-test, SPSS 8.0 for windows. Results: The temperature difference between Rt and Lt Gimun which are in upper abdomen shows statistically significant result in study group. Conclusion: The dysmenorrhea patients show larger temperature difference between Rt and Lt points in upper abdomen than normal persons. In lower abdomen, the temperature between control and study group shows little difference.

Issues related to the control of seizures and bleeding, as well as behavioral management due to mental retardation, render dental treatment less accessible or impossible for patients with Sturge-Weber syndrome (SWS). A 41-year-old man with SWS visited a dental clinic for rehabilitation of missing dentition. A bilateral port-wine facial nevus and intraoral hemangiomatous swollen lesion of the left maxillary and mandibular gingivae, mucosa, and lips were noted. The patient exhibited extreme anxiety immediately after injection of a local anesthetic and required various dental treatments to be performed over multiple visits. Therefore, full-mouth rehabilitation over two visits with general anesthesia and two visits with target-controlled intravenous infusion of a sedative anesthesia were planned. Despite concerns regarding seizure control, bleeding control, and airway management, no specific complications occurred during the treatments, and the patient was satisfied with the results.

It is well known that many patients with trigeminal neuralgia suffer from electric shock-like stabbing pains. The pain can be triggered by nonnoxious stimuli such as touching of the face, chewing, talking or swallowing. This 62 year old woman was urgently admitted to the internal medicine department due to abdominal distention and severe general weakness. She has suffered characteristic violent pain triggered by chewing and swallowing for little over 4 years. This resulted in poor oral feeding for prolonged period which left her severely debilitated. The large amount of ascites that developed 20 days before admission and extreme emaciation forced her to bed rest. She also suffered from Herpes Zoster. After medical treatment to improve liver function and severe pain was persisted, the patient was referred to our department for control of pain. We performed right mandibular block with 1% dibucaine 0.4 ml and the effect was excellent. After the pain had subsided, patient was able to take meals more comfortably and improved liver function returned.

The author reported treatment experiences of 4 cases with test anxiety. The first one was a 15 year old boy with problem of mild attention deficit which caused test anxiety and academic underachievement around the 8th grade in middle school. The second and the third cases were brother and sister. The test anxiety was caused basically due to the problem of mother child relationship. their mother expected too much of her son and always urged him to study and never left him alone. The mothers practically gave up her whole life to devote to oversee her son's academic achievement and her daughter experienced affectional deprivation. The fourth case, a 16 year old boy, was a borderline personality disorder with extreme anger and hostility toward his parents who controled him too much. Different therapeutic approaches appropriate for different cases were described and the relationship between test anxiety and various psychopathology was discussed.
