Objective: A clinical contents model is an essential data model to exchange clinical data, among existing computer systems and enhance consistency of necessary data, in terms of its meaning and reusability. However, there has not been a domestic case where such clinical model is developed till present. Methods and Results: This research is based on determining principles of developing clinical information model which is a specified model of Health level 7 Reference Information Model and attempts to identify clinical contents with types of ENTITY-ATTRIBUTE-VALUE, based on terminology standard by clinicians and domain modelers. Conclusion: This model is projected to be utilized in the next generation of EMR as core contents.

The digital tachograph is a device that automatically records speed and distance of a vehicle, together with the driver's activity and vehicle status at an accident. It records vehicle speed, break status, acceleration, engine RPM, longitude and latitude of GPS, accumulated distance, and so on. European Commission regulation made digital tachographs mandatory for all trucks from 2005. Republic of Korea made digital tachographs mandatory for all new business vehicles from 2011 and is widening the range of vehicles that must install digital tachographs year by year. This device is used to analyze driver's daily driving information and car accidents. Under a car accident that makes the device reliability unpredictable, it is very important to store driving information with maximum reliability for its original mission. We designed and implemented a practical digital tachograph. This paper presents a storage scheme that consists of a first storage device with small capacity at a high reliability and a second storage device with large capacity at a low cost in order to reliably records data with a hardware at a low cost. The first storage device records data in a SLC NAND flash memory in a log-structured style. We present a reverse partial scan that overcomes the slow scan time of log-structured storages at the boot stage. The scheme reduced the scan time of the first storage device by 1/50. In addition, our design includes a scheme that fast stores data at a moment of accident by 1/20 of data transfer time of a normal method.

This study aims to present ways to enhance the stabilization of electronic medical records, ensure the commitment to filling in information of the medical record and improve the overall quality Electronic Medical Record(EMR) information. For that purpose, the present state of the incomplete record rate and the doctor's satisfaction in Electronic Medical Record(EMR) have been surveyed by comparing and analyzing Paper-based Medical Record(PMR) and Electronic Medical Record(EMR). The survey was conducted on 31 doctors in charge of EMR system and each PMR and EMR inpatients were collected for a period of 5 months and analyzed. The results showed that the doctor's satisfaction level was higher for EMR, and the rate of incomplete record appeared to be lower in EMR in departments of both internal and external medicine. In this context, it can be said that the higher efficiency of EMR helped accomplish the increase in commitment to completing medical record information and improve the quality of the data.

환경부나 지방자치단체에서는 환경문제를 사전에 예방할 수 있는 체계를 마련하기 위하여 오염물질 배출업체가 환경감시 시스템을 통하여 환경오염물질의 배출상태를 실시간으로 측정하여 공시하도록 의무화 하고 있다. 그러나 환경단체나 지역주민들은, 환경부나 지방자치단체에 제공된 환경정보에 대한 신뢰감이 부족한 현실이다. 본 논문에서는 환경정보의 신뢰성 제공을 위하여 암호학적 인증 메커니즘을 이용한 환경정보 인증 서브 시스템을 설계, 구현하였다. 제시한 환경정보 인증시스템에서는 클라이언트/서버간 인증, 환경정보에 대한 무결성 보장 및 접근통제, 감사기록의 기능을 제공한다.

SNOMED CT is a standard clinical terminology to provide a standardized way for recording and managing of clinical records in EMR systems. However, because of its huge expressive power, it is very difficult to consistently record patients' status such as diagnosis and procedure. The reason is that one clinical meaning can be expressed in variety of ways using multiple terminologies and vice versa. This paper proposes a novel requirement of effective search browser for SNOMED CT terminologies by analyzing duplicated or similar terminologies.

SNOMED CT is a standard clinical terminology which is to efficiently record, manage and utilize clinical records during clinical processes. However, huge expressive power of SNOMED CT makes it difficult to select appropriate terms during short consultation hours. In addition, true meaning of a written record using the terminology may be misunderstood or even distorted since one clinical meaning could be expressed in a variety of ways. This paper analyzes such known problems in a database point of view, and presents effective selection methods of similar terminologies to mitigate the problem.

Background : The committee of tuberculosis(TB) survey planning for the year 2000 decided to construct the Korean Tuberculosis Surveillance System (KTBS), based on a doctor's routine reporting method. The successful keys of the KTBS rely on the precision of the recorded TB notification forms. The purpose of this study was to determine that the accuracy of the TB notification form written at a private general hospital given to the corresponding health center and to improve the comprehensiveness of these reporting systems. Materials and Methods : 291 adult TB patients who had been diagnosed from August 2000 to January 2001, were enrolled in this study. The lists of TB notification forms were compared with the medical records and the various laboratory results; case characteristics, history of previous treatment, examinations for diagnosis, site of the TB by the international classification of the disease, and treatment. Results : In the list of examinations for a diagnosis in 222 pulmonary TB patients, the concordance rate of the 'sputum smear exam' was 76% but that of the 'sputum culture exam' was only 23%. Among the 198 cases of the sputum culture exam labeled 'not examined', 43(21.7%) cases proved to be true 'not examined', 70 cases(35.4%) were proven to be 'culture positive', and 85(43.0%) cases were proven to be 'culture negative'. In the list of examinations for a diagnosis in 69 extrapulmonary TB patients, the concordance rate of the 'smear exam other than sputum' was 54%. In the list of treatments, the overall concordance rate of the 'type of registration' in the TB notification form was 85%. Among the 246 'new' cases on the TB notification form, 217(88%) cases were true 'new' cases and 13 were proven to be 'relapse', 2 were proven to be 'treatment after failure', one was proven to be 'treatment after default', 12 were proven to be 'transferred-in' and one was proven to be 'chronic'. Among the 204 HREZ prescribed regimen, 172(84.3%) patients were taking the HREZ regimen, and the others were prescribed other drug regimens. Conclusion : Correct recording of the TB notification form at the private sectors is necessary for supporting the effective TB surveillance system in Korea.

As more and more research and companies use health care data, efforts are being made to vitalize health care data worldwide. However, the system and format used by each institution is different. Therefore, this research established a basic model to classify text data onto multiple institutions according to the type of the future by establishing a basic model to classify the types of medical records of the EEG Report. For EEG Report classification, four deep learning-based algorithms were compared. As a result of the experiment, the ANN model trained by vectorizing with One-Hot Encoding showed the highest performance with an accuracy of 71%.
