  • 1. Objective : This study aimed to know the concordance coefficient and diagnostic trend of 6 Sasang constitution diagnosis factors among experts, which are important to diagnose Sasang constitution. 2. Methods : We suggested each 100 cases containing body shape, face, temperament, physiological and pathological symptom and constitutional drug response to 2 groups experts, and researched expert opinions. We analyzed concordance coefficient with Kendall's coefficient of concordance W. 3. Results : 1) Experts agreed with 167(82.5%) diagnosis results of cases, but there were 33 cases(17.5%), with which even one expert disagreed 2) The concordance of priority order of Sasang constitutional factors was significantly associated within expert. 3) Experts put the priority concordance to drug response and Face, body shape, voice and Pathological and physiological symptoms in order. 4) In case by case, concordance coefficient was 47(55.9%) in group 1, 9(10.8%) in group 2, 56 (33.5%) in total. 4. Conclusions : Experts made much account of drug responses and faces in diagnosing Sasang constitution. but there were different opinions in concordance coefficient. So Sasang Constitution Diagnosis Guideline is necessary to integrate experts opinions.

  • In this paper, we implemented on the classifier for differential diagnosis of laryngeals disease which is normal, polyp, nodule, palsy, and each step of glottic cancer using hierarchical neural network. We conducted on classifier of various vowels as /a/, /e/, /i/, /o/, /u/ from normal group, laryngeal disease group, each step of cancer group. The experimental result on classification of each vowels as follows. A /a/ vowel shows excellent classification result to the other vowels in regard to each Input parameters. Thus we implemented the hierarchical neural network for differential diagnosis of laryngeals disease using only /a/ vowel. A implemented hierarchical neural network is composed of each other laryngeals disease apply to each other parameter in each hierarchical layer. We take the voice signals from patient who get the laryngeal disease and glottic cancer, and then use the APQ, PPQ, vAm, Jitter, Shimmer, RAP as input parameter of neural networks.

  • A medical teleconferencing and medical image transmision system has been developed for diagnosis of the medical images between the medical doctors who are far away. The medical teleconferencing system transmits the voice and image of the doctors using the video and audio capture boards. The medical image transmission system software uses the medical image standard DICOM 3.0 for the future expansibility and the open system interconectivity. The medical images usually use CR images.

  • There are great needs for checking machine operation status precisely in the iron and steel plants. Rotating machines such as pumps, compressors, and motors are the most important objects in the plant maintenance. In this paper back-propagation neural network is utilized in diagnosing rotating machines. Like the finger print or the voice print of human, the abnormal vibrations due to axis misalignment, shaft bending, rotor unbalance, bolt loosening, and faults in gear and bearing have their own spectra. Like the pattern recognition technique, characteristic. feature vectors are obtained from the power spectra of vibration signals. Then we apply the characteristic feature vectors to a back propagation neural net for the weight training and pattern recognition.

  • Eagle syndrome is a rare condition caused by elongation of the styloid process or calcification of the stylohyoid ligament. Patients with Eagle syndrome typically present with dysphagia, dysphonia, cough, voice changes, otalgia, sore throat, facial pain, foreign body sensation, headache, vertigo, and neck pain. Here we report a case in which the patient initially presented with sore throat, left-sided facial pain, and cough. This case report provides a brief review of the diagnosis and nonsurgical management of this rare syndrome.

  • A 7-year-old castrated male domestic short-hair cat presented with anorexia, constipation, depression, and voice alteration. Physical and neurological examinations revealed hyperthermia ($40.5^{\circ}C$), ventroflexion of the neck, reduced responses to external stimuli, generalized muscle weakness, and exercise intolerance. Thoracic radiographs revealed the presence of a cranial mediastinal mass. The history, clinical signs, and other examination results were compatible with acquired myasthenia gravis (MG). Acetylcholine receptor (AChR) antibody titers were determined to confirm MG and the serum AChR antibody concentration was 1.24 nmol/L (reference interval, < 0.3 nmol/L). This is the first diagnosis of acquired MG in a cat in Korea.

  • Among the patients presented with the chief complaint of voice change, the one with unilaterally injected vocal fold was occasionally found at the out patient clinic. The most patients had rarely improved in symptom with conservative treatment under the impression of chronic laryngitis. Some papers were reported that the injected vocal fold(s) is due to laryngeal tuberculosis hick is sometimes associated with pulmonary tuberculosis. We investigated six patients presented unilaterally injected vocal fold with videolaryngoscope and performed histopathologic confirm with laryngeal biopsy respectively. There were low cases of laryngeal tuberculosis, one case of squamous cell carcinoma and one case of chronic larngitis. Proper management was done according to the tissue diagnosis. Pretretment and posttreatment videolaryngoscopic findings as well as some literature review were done.

  • This paper introduces an automatic voice classification system for the diagnosis of individual constitution based on Sasang Constitutional Medicine (SCM) in Traditional Korean Medicine (TKM). For the developing of this algorithm, we used the voices of 473 speakers and extracted a total of 144 speech features from the speech data consisting of five sustained vowels and one sentence. The classification system, based on a rule-based algorithm that is derived from a non parametric statistical method, presents binary negative decisions. In conclusion, 55.7% of the speech data were diagnosed by this system, of which 72.8% were correct negative decisions.

  • Sound pressure level, subglottic air pressure, vital capacity, adduction/abduction rate, and phonatory efficiency were measured in 19 opera singers, 17 Korean traditional 'Pansori' singers, and 20 non-singers; subjects' mean age was 25.9(SD=7.2) and the singers had been singing professionally for 5-10 years. One-way ANOVA and Scheff$\w'{e}$ post-hoc analysis were used to analyze aerodynamic data and to identify significant differences among groups. Sound pressure level, peak subglottic air pressure, and phonatory efficiency were found to be significantly different among three groups of the subjects. Differences in aerodynamic properties were discussed for their significance in diagnosis and treatment of voice disorders in professional singers.

  • The human speech sounds are use to diagnosis in oriental medicine with ‘0-sung’theory. In general, human voice are sound waves which generated by phonation. Two major parts of phonation are vocal cords and vocal tract. The uniqueness of individual vocal sound depend on structure and usage of their vocal cords and tract. In the oriental medicine, “0-sung (5-tones)” has been used to classify constitution of human body In order to characterize the “0-sung”, their frequency characteristics are investigated, and a principal frequency component is extracted. Then, the principal component is applied to classify sounds into “0-sung.”
