From all possible chinese medical literatures, I studied the history of chinese pediatrics by dividing into Chunqiu Zhanguo, QinHan dynasties, LiangJin, SuiTang five dynasties, Song Dynasty, Jin and Yuan dynasties, Ming Qing dynasties. The conclusions are summarized as followings 1. The mentions related with pediatrics existed already in Yan ruins turtle shell letters, and 〈Yellow Emperor's classic of internal medicine> in Chunqiu Zhanguo time formed the system of medicine, established the theoretical foundation. 2. Chang Ji established the system of diagnosis and treatment based on overall analysis of symptoms and signs in , and later pediatricians commonly applied his prescriptions to the febrile diseases. 3. The period from LiangJin to SuiTang, Pediatrics was established as special department then in , Chao Yuanfang stated the etiology, pathogenesis, symptomatology of pediatric diseases. 4. In Song dynasty. pediatric 4 major, symptoms that had been mentioned from SuiTang dynasties, were clearly established, pediatrical special books were published, and written by Qian Yi who is considered as the founder of chinese pediatrics, established the foundation of pediatrical division formation in distinction from adult fields. 5. In Jin and Yuan dynasties, four eminent physicians established the actual relationship between the theories and practical applications and insisted various and creative theories based on the classical medicine, for example, the theory that fire and heat in the body was the main cause of diseases of Liu Wansu purgation theory of Zhang Congzheng, qi regulating theory of Liu Gao, ministerial fire theory and the theory that yang is ever in excess while Yin is ever deficient of Zhu Zhenheng, etc, and they applied those theories to pediatrical various sides. 6, In Ming Qing dynasties, pediatrical specialists and pediatrical publications had increased, eg, father and son Xue Kai Xue Ji, Wan Quan, Lu Bai-si, etc in Ming dynasty, Ye Gui, Chen Fuzheng, Xia Ding, etc in Qing dynasty were famous as pediatricians. Specially, the doctrine of epidemic febrile diseases at that time showed prominent effects to children's epidemic febrile diseases.

Objectives : The objective of this paper is to examine the pathology and treatment methods of tinnitus and deafness. Methods : Contents on the ears, pathology and treatment methods of tinnitus and deafness in the Donguibogam were examined. Results & Conclusions : Findings indicate that Kidney jing deficiency and problems of qi metabolism of the Kidney are at the root of tinnitus and deafness pathology. In treatment, once the primary symptoms are managed, the root, which is Kidney deficiency, needs to be improved, together with life style management. In the case of Heart-Kidney disconnection, the Heart must be collected while nurturing jing; in the case of yin deficiency and flaring, ministerial fire must be managed while tonifying jing and blood. If the cause lies in the Lungs and Kidney, they must be tonified, while in cases due to problematic water fluid metabolism, phlegm-fire or exterior pathogens, the Kidney needs to be dealt with even after treating the aforementioned causes.

Currently, Korea is an aging society and is expected to become a super-aged society in about four years. X-ray devices are widely used for early diagnosis in hospitals, and many X-ray technologies are being developed. The development of X-ray device technology is important, but it is also important to increase the reliability of the device through accurate data management. Sensor nodes such as temperature, voltage, and current of the diagnosis device may malfunction or transmit inaccurate data due to various causes such as failure or power outage. Therefore, in this study, the temperature, tube voltage, and tube current data related to each sensor and detection circuit of the diagnostic X-ray imaging device were measured and analyzed. Based on QC data, device failure prediction and diagnosis algorithms were designed and performed. The fault diagnosis algorithm can configure a simulator capable of setting user parameter values, displaying sensor output graphs, and displaying signs of sensor abnormalities, and can check the detection results when each sensor is operating normally and when the sensor is abnormal. It is judged that efficient device management and diagnosis is possible because it monitors abnormal data values (temperature, voltage, current) in real time and automatically diagnoses failures by feeding back the abnormal values detected at each stage. Although this algorithm cannot predict all failures related to temperature, voltage, and current of diagnostic X-ray imaging devices, it can detect temperature rise, bouncing values, device physical limits, input/output values, and radiation-related anomalies. exposure. If a value exceeding the maximum variation value of each data occurs, it is judged that it will be possible to check and respond in preparation for device failure. If a device's sensor fails, unexpected accidents may occur, increasing costs and risks, and regular maintenance cannot cope with all errors or failures. Therefore, since real-time maintenance through continuous data monitoring is possible, reliability improvement, maintenance cost reduction, and efficient management of equipment are expected to be possible.

The thermo-flow field in road tunnel is influenced by some facts such as piston effect of vehicle's move, operation of ventilation facilities, natural wind and buoyancy effect of fire plume. Among those, piston effect is one of primary causes for formation of air flow in road tunnel and has an effect on initial direction of smoke flow in tunnel fire. In this study to analyze the unsteady flow in the tunnel caused by the run of vehicle, the experimental study of vehicle-induced unsteady flow on a reduced-scale model tunnel is presented. While the three types of vehicle shape such as basic type of rectangular shape, diamond-head type and stair-tail type are changed, the pressure and air velocity variations with time are measured. The rising ratio of pressure and velocity are in order of "basic type of rectangular shape > stair-tail type > diamond-head type". The experimental results would be good data for development of a numerical method on the vehicle-induced unsteady tunnel flow.

Objective: In order to find oriental medical therapies on Parkinson's disease and to make a fundamental basis for clinical application, this study was performed. Methods: We reviewed 35 kinds of the ancient and modern text, and related articles. Results: Parkinson's disease is an extrapyramidal disease characterized by akinesia, tremor at rest, rigidity, and slowness of movement. In old oriental medical text, Parkinson's disease is described as Jinjeon(振顫), Chi, Gyeong (痙), Gyejong, Ryeon(攣) and Pyeongo(偏枯), Tantan, Jungbu(中腑症) of Jungpung(中風). According to the text, major pathological causes were Wind(風), Fire(火), Phlegm(痰), and Blood stasis(瘀血). And Parkinson's disease can be classified into four clinical types as liver & kidney yin-deficiency, qi & blood deficiency, retention of phlegm-heat, and qi-stagnation & blood stasis. Standardized acupuncture points are GV20, GB20, GV14 on head, CV12, ST25 on abdomen, GV26, ST7, GB1, S14, LI20 on face, LI4, LI11, TE5, SI3, HT3, LI15, SI6 on upper extremity, and ST36, GB34, SP6, LR3, KI1, GB30, BL40 on lower extremity. Other methods, such as scalp acupuncture, electro-acupuncture, and herb-acupuncture, can be applied to treat Parkinson's disease. Conclusions: We find out that there are oriental medical concepts related with Parkinson's disease such as Jinjeon(振顫), Chi, Gyeong (痙), Gyejong, Ryeon(攣) and Pyeongo(偏枯), Tantan, Jungbu(中腑症) of Jungpung(中風), of which major causes are Wind(風), Fire(火), Phlegm(痰), and Blood stasis(瘀血). We can also apply many effective acupuncture points and acupuncture therapies according to differential diagnosis, for example, liver & kidney yin-deficiency. qi & blood deficiency, retention of phlegm-heat, and qi-stagnation & blood stasis.

During the winter season, when electricity usage increases rapidly every year, fires are frequent due to short circuits in aging electrical facilities in multi-use facilities such as traditional markets and jjimjilbangs, apartments, and multi-family houses. Most of the causes of such fires are caused by excessive loads applied to aging wires, causing the wire covering to melt and being transferred to surrounding ignition materials. In this study, we implement a system that measures the overload and overheating of the wire through a composite sensor, detects the toxic gas generated there, and logs it to the server through the gateway. Based on this, we will develop a platform that can predict, alarm and block electric fires in real time through big data analysis, and a simulator that can simulate fire occurrence experiments.

I selected the theory of blood stasis and wetness-phlegm among the major 4 causes of Joong Poong(C.V.A.)(wind. fire. deficiency of vital energy and wetness-phlegm) and recent etiology of blood stasis. An experimental studies were done to investigate the effects of Danggieum (removing blood stasis and promoting blood circulation) and Ijintang(dissipating wetness-phlegm) on thrombosis and elevated blood viscosity. The results were as follows; 1. The number of platelets were significantly increased in only Danggieum group. 2. Related to the amount of fibrinogen. only Danggieum group revealed some increase. but both groups revealed no significance. 3. Related to the prothrombin time. Danggieum and Ijintang groups had significant decrease. but Danggieum group revealed more significance. 4. Related to the degree of concentration of FDP, only Danggieum group had significant decrease. 5. Whole blood viscosity and plasma viscosity in lower shear rates. both groups of Danggieum and Ijintang had significant decrease. 6. Related to the amount of RBC. both groups of Danggieum and Ijintang had significant decrease. 7. Related to the change of hematocrit. only Danggieum group, and the change of hemoglobin. only Ijintang group had significant decrease. 8. Related to the change of body temperature. only Ijintang group had significant raise. 9. Related to the changes of WBC. glucose, albumin, total protein and body weight. Danggieum and Ijintang groups had each increase or decrease. but no significance. According to the above results, Danggieum had more significant effect than Ijintang on the thrombosis. and Ijintang had more significant effect than Danggieum on the elevated blood viscosity. And it is considered that it might be more effective in treating Joong-Poong(C.V.A) to take medicines regarding patient's constitution and symptoms as well as the causes of Joong-Poong(C.V.A)

Background : Tinnitus is common disorder with many possible causes and a symptom of many different diseases but has no effective treatment. Most of tinnitus patients experience the disorder to a degree that their quality of life and productivity are impaired. Especially tinnitus accompanied hearing loss causes severe discomfort in patients. Objectives : 1. Through symptoms of tinnitus, we tried to find out the relationship of Heo-sil(虛實) and Zuang fu bian zheng(臟腑辨證) among tinnitus patients accompanied Hearing Loss. 2. By testing THI, we tried to evaluate the quality of life of tinnitus patients group and tried to compare the quality of life between high-narrow tone and low-wide tone tinnitus patients group. 3. In the future, this study was planned to help monitor the prognosis and determine the progress of treatment for tinnitus patients who also have hearing loss. Methods : 43 patients were recruited in this study who was ill with tinnitus accompanied hearing loss. They wrote out the questionnaire about tinnitus and the Tinnitus Handicap Inventory(THI). Results : 1. In tinnitus patients, there were more men than women accompanied hearing loss. The rate of visits was higher as the age increased. 2. Most of the patients who visited the hospital had sensitive hearing loss. 3. In high-narrow tone tinnitus group, phlegm fire congesting-type are more uncomfortable than spleen-stomach weakness-type. 4. In low-wide tone tinnitus group, liver qi depression was the most uncomfortable. Conclusions : The present study suggests that tinnitus pattern may be helpful in differentiating patients with tinnitus, and the effectiveness of treatment can be predicted through differentiation. Zuang fu bian zheng(臟腑辨證) and Distinguishing between Heo(虛) and Sil(實) is expected to have positive effects on tinnitus accompanied hearing loss treatment.
