  • Recently, there are deep and much concerns about the objective assessment of diagnosis in Oriental Medicine. Among them, pulse diagnostics is used for the quantitative device of diagnosis. The objective research of pulse diagnosis were mainly conducted by pulse wave. So it is important to gain multi-information for the quantification of pulse diagnosis. We report the development of pulse diagnostic apparatus enable to gain the multi-information, detect the pressure pulse wave in conku(寸口) area and obtain the gradient curve and original pulse wave simultaneously, and consider the pulse wave with the traditional pulse diagnosis at the same time.

  • Several off-line diagnostic tests which include the insulation resistance(IR), polarization index(PI), low-voltage AC, and recurrent surge oscillograph(RSO) tests were performed to assess the condition of generator rotor windings. The low-voltage AC and the RSO tests were performed on the gas turbine generator rotor winding to detect shorted turns. Before intentionally applying artificial shorted faults, it was confirmed by the low voltage AC and the RSO tests that the winding was in sound condition. For simulated shorted rotor winding turns, the RSO test detected the fault in the winding. The RSO test was capable of identifying the number and pole location of the shorted turns for a number of simulated shorted coils.

  • Gated myocardial SPECT and attenuation correction gave birth to new insights into the pathophysiology of ischemic myocardial perfusion and function in clinical routine practice. Gated myocardial Tc-99m-compound SPECT improved diagnostic accuracy of coronary artery disease and enabled us to observe motion and thickening of myocardial walls as well as myocardial perfusion at the same time. Quantitative and qualitative assessment of myocardial performance and perfusion let us to understand the myocardial physiology in ischemia and infarction. In every patient who underwent gated perfusion SPECT, we will find ejection fraction, left ventricular volumes and regional wall motion. There are hopes to use gated TI-201 SPECT for the same purpose and to use gated SPECT for evaluation of wall motion and thickening at stress or immediate post-stress. Attenuation correction could improve diagnostic accuracy mainly by increasing normalcy ratio or performance of non-expert physicians. Both gated methods and attenuation correction improved specificity of non-expert physicians in diagnosing patients with moderate pretest likelihood. New imaging techniques will fill the desire of cardiologists to examine function and perfusion, and possibly metabolism in their clinical routine practice.

  • Scince $^{201}$TI was introduced as a myocardial perfusion imaging agent in the early 1970s, scintigraphic evaluation of myocardial perfusion for the diagnosis of coronary artery disease is a valuable noninvasive diagnostic imaging modality. Stress radionuclide myocardial perfusion imaging is widely accepted to have high diagnostic and prognostic use in the assessment of patients with known or suspected coronary artery disease. With wise use of this nonivasive imaging technique, more patients are referred for stress perfusion imaging. Until now various protocols for stress testing and myocardial imaging were developed and used in worldwide. This article presented various protocols of stress testing and myocardial imaging for clinical use.

  • $^{18}F-FDG$ PET in combination with conventional imaging modalities could help avoid unnecessary biopsy for the primary mass, and it also has a high diagnostic accuracy in patients with dense breasts. In the assessment of metastasis, $^{18}F-FDG$ PET was useful to select patients who required sentinel lymph node biopsy and to detect extra-axillary lymph node metastasis and distant metastasis. To increase the sensitivity for osteoblastic bone metastasis, bone scintigraphy should be added. In the detection of recurrence, $^{18}F-FDG$ PET showed a higher diagnostic accuracy than tumor marker or computed tomography, and therefore it can be used in routine breast cancer follow-up. $^{18}F-FDG$ PET has been reported that it correctly predicted the response of neoadjuvant chemotherapy on as early as 8th day of treatment. Therefore, it is useful for the early detect of therapeutic response in advanced breast cancer.

  • This test was performed to assess the insulation deterioration condition of the stator winding of Chung-Ju hydrogenerator #4 and Dae-Cheong hydrogenerator #2 which had been in service after being constructed 1980. The insulation diagnostic tests include resistance polarization index(P.I.) AC current, dissipation factor(Tan ${\delta}$) and partial discharges ($Q_{max}$). The results of diagnostic tests were compared to factory test measurements.

  • The full-field digital mammography (FFDM), which has been known as a digital breast imaging system, carries out more outstanding performance than the screen-film mammography in overall image quality, skin & nipple, description of pectoral muscle and expression of micro-calcification. Thus, in this thesis, I perform experiments for both the enhancement of image quality and accurate estimation of the result in question, when detecting the very tiny-sized lesions in mammography. The image of digital breast X-rays is the important diagnostic tool for detecting early breast cancer and micro calcification lesion. The experiment of how much compression rate has an effect on the result of diagnosis in the case of microcalcification lesion, with JPEG2000 40:1 compression and over 50% enlargement led to obscure or definitely unacceptable diagnostic results is performed. And in another study of assessment of PSNR degree. I recognized the importance of standardized management system in mammography, where not to mention the accurate reading of the image has the most crucial role in diagnosis

  • Diagnosis of a patient with dysphonia begins with a thorough history and physical examination. Larynx can be visualized either indirectly or directly with a rigid or flexible laryngoscope. One notable limitation of simple indirect laryngoscopy is that the examination dose not yields a recordable and reproducible image of the larynx and vocal tract. And unaided human eye is unable to visualize the vibratory patterns of the true vocal cord during phonantion. When available, stroboscopy provides useful information regarding vocal told closure, vibration, and mucosal wave which is useful to decide between microsurgery, vocal reeducation or a combined treatment Even there are some limitations, recognition of the advantages and disadvantages of stroboscopy allows for optimal appreciation and stroboscopy remains an essential diagnostic tool in the assessment of dysphonia.

  • Background: Infectious mononucleosis is a disease precipitated by Epstein-Barr virus(EBV) in mostly children, some seronegative adolescents and young adults comprising clinical symptoms such as fever, lymphadenopathy, and pharyngitis as well as laboratory findings such as hetero-phil antibodies and atypical lymphocytosis. It is confirmed by serologic test for EBV. Materials and Methods: A retrospective evaluation of 26 patients who diagnosed with infectious mononucleosis was peformed through the analysis of typical symptom, sign and laboratory findings. Results : Infectious mononucleosis occurs mostly at 3 to 10 years (74.9%), common symptoms and signs are fever, cervical lymphadenopathy, tonsillar enlargement and exudate. Positive ratio of atypical Lymphocyte(>10%) and hetrophil antibodies are 61.5%, 35.2% respectively, it is less diagnostic. EBV-viral capsid antigen(VCA) IgM are positive in all cases, so it is most diagnostic findings. Conclusion: Infectious mononucleosis should be considered as a cause of cervical lymphadenopathy and pharyngotonsillitis in children and young adults, the assessment of EBV-VCA IgM is necessary for the diagnosis.
