  • Nowadays, Cars are continuing to grow at an alarming rate but they also cause many problems such as traffic accident, pollutions and so on. One of the most effective methods that prevent traffic accidents is the use of traffic monitoring systems, which are already widely used in many countries. The monitoring system is beginning to be used in domestic recently. An intelligent monitoring system generates photo images of cars as well as identifies cars by recognizing their plates. That is, the system automatically recognizes characters of vehicle plates. An automatic vehicle plate recognition consists of two main module: a vehicle plate locating module and a vehicle plate number identification module. We study for a vehicle plate number identification module in this paper. We use image preprocessing, feature extraction, multi-layer neural networks for recognizing characters of vehicle plates and we present a feature-comparison method for improving the performance of vehicle plate number identification module. In the experiment on identifying vehicle plate number, 300 images taken from various scenes were used. Of which, 8 images have been failed to identify vehicle plate number and the overall rate of success for our vehicle plate recognition algorithm is 98%.

  • Objective : The purpose of this paper is to report the improvements of a patient who has suffered from aftereffects following stroke such as dysgraphia and articulation disorder, which is treated by herbal medication based on Shanghanlun disease pattern identification diagnostic system. Methods : According to 'Disease Pattern Identification Diagnostic System based on Shanghanlun Provisions', the patient was diagnosed as Taeyang-byung Gyeolhyung and number 138 provision, and was administered Sohamhyung-tang for 90 days. We recorded the progress of improvements based on the patient's statement and documented the patient's writing Results : The patient can write the letters such as U, 2, ㄹ,ㅇ more clearly and become confident on both writing and speaking. Conclusions : This case shows the effects of Sohamhyung-tang on aftereffects following stroke such as dysgraphia and articulation disorder. It was induced according to the 'Disease Pattern Identification Diagnostic System based on Shanghanlun Provisions' so that it suggest a potential interpretation, which is different with it of the text books Herbal Formula Science and Sanghallonjeonghae, on the provision no. 138. Also the usage of Sohamhyung-tang in this case may support the way far from the diagnosis of oriental neurological medicine, which explain the pathology of stroke as fire-heat(火熱), dampness-phlegm(濕痰), static blood(瘀血) and dual deficiency of qi and blood(氣血兩虛).

  • Objective: This study aimed to report the improvement of a patient with chronic insomnia who was treated with Baekho-tang based on the Shanghanlun disease pattern identification diagnostic system (DPIDS). Methods: The patient's symptoms were checked on days 19, 37, and 52 after taking Baekho-tang. Chronic insomnia was evaluated by the degree of insomnia, hours spent asleep, and the number of times the patient woke up during the night, which were all assessed by a visual analog scale (VAS) with the Leeds Sleep Evaluation Questionnaire. In addition, new clinical implications for the interpretation of the 350th Shanghanlun provision were reviewed. Results: After administering Baekho-tang for 52 days, based on the 350th Shanghanlun provision according to the DPIDS, the VAS score decreased from 10 to 1. Conclusions: The patient recovered from chronic insomnia. This case report suggests that the words "滑," "厥," and "裏" in the 350th provision of Shanghanlun mean physical and psychological causes of insomnia. In addition, Baekho-tang had a therapeutic effect in improving the chief complaint of the patient. Therefore, the interpretation of the 350th Shanghanlun provision requires a new definition that includes the patient's lifestyle, family conflict, and past history of the patient as a cause of chronic insomnia.

  • Objective : This study aimed to report the improvement of a patient with anorexia by treatment with Jinmu-tang (Hyunmu-tang) based on the disease pattern identification diagnostic system (DPIDS) of the Shanghanlun provisions. Methods : We evaluated the progress of symptoms, patient compliance, and presence of side effects after the patient was administered Jinmu-tang. The clinical response was estimated according to the number of meals a day, the size of meals, the number of complaints of abdominal pain in a week, and a Likert scale. Results : According to the DPIDS, the patient was diagnosed according to provision 316 with soyinbing. After administration of Jinmu-tang for 45 days, the number of meals a day and the size of meals increased, the number of complaints of abdominal pain in a week decreased, and the Likert scale score decreased from 3 to 0. Conclusions : This case report suggests that the word "腹痛" (abdominal pain) in the 316th Shanghanlun provision indicates anxiety about abdominal pain, which affected anorexia in this case.

  • Ubiquitous location based services (u-LBS) will be interested to an important services. They can easily recognize object position at anytime, anywhere. At present, many researchers are making a study of the position recognition and tracking. This paper consists of postion recognition and user identification system. The position recognition is based on location under services (LBS) using a signal strength map, a database is previously made use of empirical measured received signal strength indicator (RSSI). The user identification system automatically controls instruments which is located in home. Moreover users are able to measures body signal freely. We implemented the multi-hop routing method using the Star-Mesh networks. Also, we use the sensor devices which are satisfied with the IEEE 802.15.4 specification. The used devices are the Nano-24 modules in Octacomm Co. Ltd. A RSSI is very important factor in position recognition analysis. It makes use of the way that decides position recognition and user identification in narrow indoor space. In experiments, we can analyze properties of the RSSI, draw the parameter about position recognition. The experimental result is that RSSI value is attenuated according to increasing distances. It also derives property of the radio frequency (RF) signal. Moreover, we express the monitoring program using the Microsoft C#. Finally, the proposed methods are expected to protect a sudden death and an accident in home.

  • This research investigates the structural health monitoring of nonlinear structures after a major seismic event. It considers the identification of flag-shaped or pinched hysteresis behavior in response to structures as a more general case of a normal hysteresis curve without pinching. The method is based on the overall least squares methods and the log likelihood ratio test. In particular, the structural response is divided into different loading and unloading sub-half cycles. The overall least squares analysis is first implemented to obtain the minimum residual mean square estimates of structural parameters for each sub-half cycle with the number of segments assumed. The log likelihood ratio test is used to assess the likelihood of these nonlinear segments being true representations in the presence of noise and model error. The resulting regression coefficients for identified segmented regression models are finally used to obtain stiffness, yielding deformation and energy dissipation parameters. The performance of the method is illustrated using a single degree of freedom system and a suite of 20 earthquake records. RMS noise of 5%, 10%, 15% and 20% is added to the response data to assess the robustness of the identification routine. The proposed method is computationally efficient and accurate in identifying the damage parameters within 10% average of the known values even with 20% added noise. The method requires no user input and could thus be automated and performed in real-time for each sub-half cycle, with results available effectively immediately after an event as well as during an event, if required.

  • Objectives: It is a statistical study to examine the data of CaPSPI (Diagnostic System for Climacteric and Postmenopausal Syndrome Pattern Identification), developed for diagnosis of menopause disorders and to record the status of treatment of it. Methods: From November 1, 2020 to June 19, 2021, 36 cases of data of 33 respondents of the CaPSPI were analyzed. For the use of the basic data of the clinical menopausal disorder, we investigated frequency of menopausal symptoms and the difference between them depending on the period of menopause, and the presentation of usage prescriptions. And the diagnostic results for three kinds' diagnosis [for examination (D1), for treatment (D2), by doctors (D3)] were compared. The diagnostic consistency of D1 and D3 and the statistical significance between DT and disease elements (證素) was investigated. Results: 1. Hot flush was the highest in the symptom survey of the menopause that the subjects complained of, followed by insomnia. There was no significant difference in symptom expression according to menopausal period. 2. The diagnostic consistency of D1 and D2 showed significant diagnostic consistency only in liver depression, and the diagnostic consistency of D1 and D3 showed significant consistency in liver depression and Dual Deficiency of Heart and Spleen. 3. D3' diagnosis and disease elements had statistical significance for cases of P<0.1 was found to be related to the theory of oriental medicine. Conclusions: It is needed to continue to accumulate diagnosis and treatment results through CaPSPI in the future to strengthen the basis for patten identification and treatment of menopause disorders.

  • 본 논문에서는 다중 시그마포인트 세트(MSP)를 사용하는 분산점 칼만필터(UKF)인 UKF-MSP를 소개한다. 비선형 동적시스템을 표현하기 위해 널리 알려진 Bouc-Wen 모델을 사용하였고, 비선형성 고려가 가능한 칼만필터 중 UKF를 선정하였다. 그런데 UKF는 두 가지 인공오차와 시그마포인트의 분포를 결정하는 스케일링 파라미터의 값을 튜닝(Tuning)하는 과정을 통해 적절히 설정해야만 대상 동적시스템의 추정하고자 하는 상태(State)를 정확히 추정할 수가 있다. 본 논문에서는 후자의 스케일링 파라미터 설정 문제를 완화하고자 하였으며, MSP를 사용함으로써 기존 UKF에 비해 칼만필터 튜닝 과정에 덜 민감한 UKF-MSP를 제안하였다. 지진으로 인한 급격한 구조손상 시나리오에 대해 UKF-MSP의 안정성을 검증하였다. 제안된 방법은 튜닝과정을 완화함과 동시에 다른 칼만필터 파라미터인 인공오차에 대해서도 덜 민감한 거동을 보임을 확인하였다.
