Purpose: The purpose of this study is to apply the machine and deep learning methodology on error terms which are continuously auto-generated on the sensors with specific time period and prove the improvement effects of power generator prediction diagnosis system by comparing detection ability. Methods: The SVM(Support Vector Machine) and MLP(Multi Layer Perception) learning procedures were applied for predicting the target values and sequentially producing the error terms for confirming the detection improvement effects of suggested application. For checking the effectiveness of suggested procedures, several detection methodologies such as Cusum and EWMA were used for the comparison. Results: The statistical analysis result shows that without noticing the sequential trivial changes on current diagnosis system, suggested approach based on the error term diagnosis is sensing the changes in the very early stages. Conclusion: Using pattern of error terms as a diagnosis tool for the safety control process with SVM and MLP learning procedure, unusual symptoms could be detected earlier than current prediction system. By combining the suggested error term management methodology with current process seems to be meaningful for sustainable safety condition by early detecting the symptoms.

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.

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.

정부는 공공데이터 품질관리 수준평가를 진행하여 공공 개방데이터의 품질관리를 진행하고 있다. 공공 개방데이터는 XML, JSON, CSV 등 여러 오픈포맷 형태로 제공되며 CSV 형식이 대다수를 차지한다. 이러한 CSV 형식의 공공 개방데이터 품질진단 시 품질진단 담당자가 공공 개방데이터 파일의 필드명과 필드 내 데이터에 의존하여 필드 별 도메인을 판단하여 진단한다. 그러나 대량의 개방 데이터 파일을 대상으로 품질진단을 수행하기 때문에 많은 시간이 소요된다. 또한 의미 파악이 어려운 필드의 경우 품질진단의 정확성이 품질진단 담당자의 데이터 이해도 역량의 영향을 받는다. 본 논문은 필드명과 데이터 분포 통계를 이용한 CSV 형식 공공 개방데이터의 도메인 판별 모델을 제안하여 품질진단 결과가 품질진단 담당자의 역량에 좌지우지 되지 않도록 일관성과 정확성을 보장하고 진단 소요 시간 단축을 지원한다. 본 논문의 모델 적용 결과 행정안전부에서 제공하는 파일형식 개방데이터 진단도구보다 2.8% 높은 약 77%의 정답률을 보였다. 이를 통해 공공데이터 품질관리 수준진단·평가에 제안 모델 적용 시 정확성을 향상시킬 수 있을 것으로 기대한다.

Background : The principal diagnosis has been used in many different fields such as hospital statistics, medical research, insurance claim, national health statistics and so on. Some principal diagnoses have a relatively low level of reliability in the medium-sized hospitals. The purpose of this study is to identify the reliability level of principal diagnoses and to suggest ways to improve reliability of the principal diagnosis. Method : Data were collected from a medium-sized hospital located in Pusan. The discharge summaries on 323 patients who were discharged in January, 2008 and the outpatient summaries on 251 patients who visited the hospital on March 28, 2008 were collected, and descriptive analysis was performed using SPSS version 12.0K. Result : The findings are the followings: (1) the diagnostic consistency rate between medical records and doctors' was 92.0%; (2) the diagnostic consistency rate between medical records and insurance claims was 86.1%; (3) the diagnostic consistency rate between doctors' diagnoses and insurance claims was 80.2%. The evidence seems to indicate that some principal diagnoses have reliability problems in the medium-sized hospitals. Conclusion : The results of this study suggest the followings: (1) employees should be trained and supervision of hospital activities are needed; (2) network systems should be constructed for each department; (3) professions need to be fostered (4) doctors' awareness of medical records should be changed.

Objectives: There were only small studies about the difference of the quality of life depending on blood stasis. We investigated that the blood stasis made the differences of quality of life. Methods: We recruited the participants stratified according to age and gender. The participants were assessed independently by two Korean medicine doctors more than 7 years of clinical experiences whether or not with blood stasis. And they responded at the questionnaire associated with blood stasis and SF-36. The analysis was done with IBM SPSS Statistics (ver. 21). Results: Total 101 participants were checked for with/without blood stasis. 40 participants were accord in the diagnosis with blood stasis by two doctors. Two researchers coincided in diagnosis with non-blood stasis in 42 participants. 19 participants showed the discrepancy between the assessment of blood stasis and they were classified as non-blood stasis. The mean age in group of blood stasis was $44.07{\pm}11.65$, it was not shown the significant difference comparing non-blood stasis group. The subscale of physical function (PF), role-physical (RP), bodily pain (BP), general health (GH), vitality (VT), mental health (MH) and role emotional (RE) in SF-36 were significantly low in the group of blood stasis. Blood test including biochemistry, fibrinogen, prothrombin time and D-dimer was not in abnormal range according to blood stasis without CRP. Conclusions: The patients that diagnosed of blood stasis showed the bad physical health status, and partially bad mental health. It is necessary to investigate whether Korean traditional treatment for blood stasis would be made improvement for quality of life. Moreover, the standardization of diagnosis on blood stasis would be needed.

Background : To examine the difference between ICD-10 and The Korean standard classification of disease(oriental medicine), and to aim at improve the practical use as statistical data. It is one of the reason of disease classification. On that account we convert the many to many correspondence presenting classification of oriental medicine into many to one correspondence. Method : The study tracked out 155 patients discharged from the university hospital which is located in Gyeonggi Province and managing hospital and oriental medicine hospital from July to October this year. The period of this study was from August 1 to November 18. We compared correspondence between the two services' diagnosis(hospital services and oriental medicine hospital services) at the same time and attempted many to one correspondence classification. That is for production of statistical data. Result : We investigated the group which have had medical treatment experience of two kinds of services at the same time. The result of this investigation was that the same oriental medicine diagnosis used differently in western medicine diagnosis. 44.5% was accorded with western medicine diagnosis. Correspondence of the western medicine diagnose with the top of the Korean standard classification of disease(oriental medicine) list's western medicine diagnosis was 13.5%. For many to one correspondence classification for statistics, one western medicine diagnosis was selected for one oriental medicine diagnosis. In case of the main diagnosis(I sign) was not enough to explain oriental medicine diagnosis' characteristic, we chose multiple other diagnosis, so other diagnosis(II sign) about patient's cause of disease could be selected for supplement after we examined the patient's records. The statistics was possible with this many to one correspondence. Conclusion : The result of this study about correspondence between western medicine diagnoses and those of oriental medicine confirms that The Korean standard classification of disease(oriental medicine) is hard to be standardized with western medicine diagnosis. Therefore, according to this study, we use new many to one correspondence classification, multiple oriental medicine diagnoses with one ICD-10, which can be used by statistical data.
