Medical diagnosis systems have been developed to make the knowledge and expertise of human experts more widely available, therefore achieving high-quality diagnosis. In this study, in order to support the diagnosis by the medical diagnosis system, we have preformed medical diagnosis inference three times: first by a neural network with the backpropagation algorithm, secondly by a discriminant analysis with all of the variables, and thirdly by a discriminant analysis with the selected variables. A discussion on comparison of these three methods has been provided.

Objectives : The paper seeks to provide a study on Bianque's Pulse Diagnosis in the contexts of Huangdi Neijing's Maijing and Nanjing. Methods : The paper provides a comparison of sentences regarding Bianque's Pulse Diagnosis discovered in Neijing, Maijing, and Nanjing. Results & Conclusions: 1. Bianque's Pulse Diagnosis was given birth through stages in accoradnce with the development of Pyobonjin, Maeggujin, Gyeongmaeghyjin, and Meridian Theory. 2. It seems that Neijing filled in Sambuguhujin and In-yeongbuyangmaegjin because they were not discovered in Canggong's Records of Diagnosis. 3. Bianque's Pulse Diagnosis diagnosed death using Osaegjin. Underneath each sentence within each biography regarding Meridian, there existed Pulse dead Hou. 4. Bianque's Pulse Diagnosis quantified the operation and length of pulse in time. The concept of small net was added which led to the establishment of Fifty circulations, Yeongwi theory, Meridians circulation, and chongu's boundary.

Telemedicine can be defined as "medical activities performed remotely by medical personnel using information and communication technology." So far, many scholars in Korea have understood that only telemedicine between medical personnel is allowed and telemedicine between medical personnel and patients is prohibited based on Article 34 of Medical Service Act. However, Article 34 is only a restriction on the performing place of medical profession, not a prohibition on telemedicine itself. And, there are no regulations prohibiting telemedicine under the korean medical law. So, it is difficult to say that telemedicine is generally prohibited under the korean medical law, apart from the health insurance medical treatment benefit standards. However, there is controversy in interpretation regarding the meaning of "direct diagnosis" in Articles 17 and 17-2 of Medical Service Act. The Constitutional Court of Korea interpreted this as "face-to-face diagnosis", while the Supreme Court of Korea interpreted it as "self diagnosis". In light of the dictionary meaning of 'direct' and the interpretation of related medical law regulations, I think the Supreme Court's interpretation is valid. Although "direct diagnosis" does not mean "face-to-face diagnosis", the concept of "diagnosis" implies "principle of face-to-face diagnosis". In addition, "non-face-to-face diagnosis" are only allowed to supplement "face-to-face diagnosis", so the problems caused by "non-face-to-face diagnosis" can be fully overcome. In the end, the limit of telemedicine is how faithful the diagnosis was.

Ultrasonographic examination in the obstetrics not only makes easy of the diagnosis of Hydrocephalus, placenta previa, anencephalus and ectopic pregnancy, etc, but also guaranteed its excellence in the diagnosis of women gynecology disease. Especially in case that it doesn't affect radiation hazard on the embryo, its efficiency keeps increasing and it is spotlighted to many clinic doctors. Even though in general hospital we often observe congenital hydrocephalus in Med. Dept. which entirly undergoes the medical examination to the insured, we don't observe even the women delivered with child and it is very difficult to find a rare congenital hydrocephlus throughout other present insurance companies. We inspected a congenital hydrocephalus, which other medical equipments of present insurance companies have many difficulties in the medical examination, accompanied by meningoencephalocele by ultrasonic diagnosis. We analyzed and compared the data by ultrasonic diagnosis with that of surgical diagnosis and the results are follows; 1) We could correctly describe meningoencephalocele by ultrasonic diagnosis. 2) It was able to be diagnosed in LMP 22 weeks. 3) BPD has about 10 mm higher than normal value in LMP 22 weeks. 4) Dilatation of lateral ventricle was observed in LMP 22 weeks. 5) As paralled with ultrasonic diagnosis in pregnancy medical examination, accepting declines including the risk rate can be restrained.

We are developing the methods for the objective and systematic diagnosis, but in actuality the relativity between a diagnosis of Korean medical doctor to a symptom of patients and the conformity to the expression of the Korean medical diagnostic mechanism is short of the statistical data. so, the questionnaire of Cold-Heat & Deficiency-Excess and a diagnosis of Korean medical doctor and a result of the Korean medical diagnostic mechanism, through the relationship of those, we have offered the objective data for diagnostic validity. The study group was 750 volunteers who diagnosed by Cold-Heat & Deficiency-Excess, out of 1475 volunteers who participated in Korean-Western medical examination. We compared the results of the questionnaires for Cold-Heat & Deficiency-Excess patternization through the questionnaire with a diagnosis of Korean medical doctor. we also studied the diagnostic validity for the item of the questionnaire by statistics analysis. It is proper that 9 questions of 16 questions for the Cold, 6 questions of 14 questions for the Heat, 13 questions of 14 questions for the Deficiency, 6 questions of 9 questions for the Excess, and there is close correlation between the questionnaire to the diagnosis. The difference between the questionnaire score is meaningful(p=0.000), this conforms to the diagnosis of the Korean medical doctor, so the questionnaire have the validity. The result of the questionnaire of Cold-Heat & Deficiency-Excess conform to a diagnosis of Korean medical doctor, it carries an important meaning by the measure of diagnosis, and it is necessary for further study for the significance of the medical diagnostic mechanism.

Background : ICD-10 Classification, which is used domestically as well as internationally, has limited use in the clinical practice since it is developed for at disease statistics and epidemiology. Therefore, the purposes of this study were to improve the quality of diagnosis by constructing a new disease classification based on the diagnoses doctors currently make in the clinical setting and connecting this classification with OCS and EMR, and to meet the demands of doctors for high quality medical study data in medical research. Methods : The specialists in each ophthalmic subfield collected clinical diagnoses and abbreviations based on the ophthalmology textbooks and confirmed the classifications. Total number of clinical diagnoses collected was totaled 672, for which ideal diagnoses had been selected and a new model of disease classification model in connection with ICD-10 was constructed. The constructed classification of clinical diagnoses consisted of six steps: the first step was the classification by ophthalmic subspecialty field; the second to fifth steps were the detailed classification by each specialty field; the sixth step was the classification by site. Results : After introducing the new disease classification, research on the use and a pre-post comparison was conducted. The result from the research on the use of the clinical diagnoses in inpatient and outpatient care has shown a gradually increasing tendency. From the pre-post comparison of EMR discharge summary diagnoses, the result demonstrated that the diagnosis was stated correctly and in detail. Since the diagnosis was stated correctly, code classification became correct as well, which makes it possible to construct high quality medical DB. Conclusion : This construction of clinical diagnoses provides the medical team with high quality medical information. It is also expected to increase the accuracy and efficiency of service in the department of medical record and department of insurance investigation. In the future, if hospitals wish to construct a classification of clinical diagnosis and a standard proposal of clinical diagnosis is presented by a medical society, the standardization of diagnosis seems to be possible.

Matrix metalloproteinase (MMP)-2 and MMP-9 are important proteases involved in invasion and metastasis of various tumors. Extra-gastrointestinal stromal tumors (EGISTs) are rare neoplasms. This study was performed to assess MMP-2 and MMP-9 expression in EGIST tissue samples for association with clinicopathological data from the patients. Twenty-one surgical EGIST tissue specimens were collected for analysis of MMP-2 and MMP-9 expression using immunohistochemistry. MMP-2 and MMP-9 proteins were expressed in all of the epithelial cell types of EGISTs, whereas they were only expressed in 75% of the spindle cell type, although there was no statistically significant difference (p>0.05). Expression of MMP-2 and MMP-9 proteins was associated with tumor size, mitotic rate, tumor necrosis, and distant metastasis (p<0.05). MMP-2 expression was linked with MMP-9 levels (p<0.05). However, there was no correlation between MMP-9 expression and age, sex, primary site, or cell morphology in any of these 21 EGIST patients (p>0.05). Moreover, expression of MMP-2 and MMP-9 proteins increased with the degree of EGIST risk. This study provided evidence of an association of MMP-2 and MMP-9 expression with advanced EGIST behavior.
