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.

This paper proposes a method of refining and processing time-series data using Medical Information Mart for Intensive Care (MIMIC-IV) v2.0 data. In addition, the significance of the processing method was validated through a machine learning-based pressure ulcer early warning system using a dataset processed based on the proposed method. The implemented system alerts medical staff in advance 12 and 24 hours before a lesion occurs. In conjunction with the Electronic Medical Record (EMR) system, it informs the medical staff of the risk of a patient's pressure ulcer development in real-time to support a clinical decision, and further, it enables the efficient allocation of medical resources. Among several machine learning models, the GRU model showed the best performance with AUROC of 0.831 for 12 hours and 0.822 for 24 hours.

SNOMED CT is a standard clinical terminology to provide a standardized way to record and manage clinical records for EMR or EHR. The structure of SNOMED CT is very complex because of huge expressive power and its internal design mechanism. Although there are some SNOMED CT browsers for browsing and searching SNOMED CT concepts, they are less effective because they do not consider such complexity of SNOMED CT. This paper depicts problems of current SNOMED CT browsers and analyze SNOMED CT dataset. Then, this paper analyze requirements of SNOMED CT browser which improves searching and selecting of appropriate clinical terms.

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.

The LEX system is a XML-based framework for medical information consolidation. The Lex makes it possible for heterogeneous HISs(Hospital Information Systems) exchange and share HL7 messages by storing the messages into a single Central Clinical Database. In this paper, we propose a HL7 message server independently interoperable from existing HIS to generate HL7 messages, and design an XML database schema suitable for storing and manipulating such data. We also propose a new DTD for efficient transformation of HL7 messages to XML documents for storage saving as well as supporting patient-oriented information retrieval.

In the recent you, as the development of computer network and web, the amount of electric document exchange is dramatically increased through B2B, B2C, electric bid and et cetera. The medical world also needs to share and exchange good information for medical treatment like H2C(hospital to hospital), H2C(hospital to company). In this paper, we design medical information model using DTD and inplement medical information support system based on xml and xslt.

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.

These days it is becoming more and more common to find electronic medical screening systems installed in Oriental hospitals and clinics. This is a relatively new development for the practice of traditional Oriental medicine. Specifically, Pulse detection machines are being utilized in order to help determine a patient's disease scientifically. However, identifying and diagnosing the specific disease correctly for each patient is still very difficult in Oriental medicine. The intention of this paper is to propose a solution which uses two separate Electronic systems working together to produce a better likelihood of finding the correct diagnosis for each patient. It is proposed that an EMR intelligent electronic chart system be developed and employed, which would utilize both Pulse wave system and a tongue detection system at the same time, in order to solve the problem. Computer simulation results have proven to show that EMR systems used in hospitals and clinics are more efficient and yield a more accurate diagnosis than traditional methods.

Electronic Medical Record(EMR) is medical record that has been saved electronically onto a computer. The standardization activities for EMR is actively underway as it may not only improve the overall quality of the medical services but as the value of medical big data (medical & IT convergence area) is being considered very important. One of the most important issues is ensuring the necessary and effectiveness of EMR standardization to the stakeholder. Researchers did an empirical study to find out how the doctors perceived the EMR standardization from both technical and economical perspective. The results of the empirical analyses showed that system quality and an economical value had a positive effect on perceived usefulness and intention to adopt EMR standardization, yet interoperability have only affected the perceived usefulness. Additionally, the economical value seemed to be the most important variable in forming a consensus in the need of EMR standardization.

지금까지 병원에서 사용하던 일반 종이차트를 벗어나 전자적으로 환자의 데이터를 기록하고 유전자 데이터를 이용하여 환자의 유사 질병까지 찾아 낼 수 있는 EMR(Electronic Medical Record 전자 의무 기록)이 개발되면서 의료계는 환자에게 더욱 신속하고 정확한 진료를 할 수 있게 되었다. 본 논문은 이에 그리드 환경을 접목하여 더 빠른 데이터 처리와 신뢰성 과 접근성을 높일 수 있는 방법을 제시한다. 첫째, 현재 기 개발된 EMR 시스템의 환경에서 인증된 사용자만이 스토리지에 접근 할 수 있도록 GSI Service를 이용하여 단일 인증 방식으로 보안성을 높이며 동시에 단 한번의 인증절차로 모든 자원을 활용 할 수 있다. 둘째, Replica Service를 이용하여 기존의 스토리지를 복제 하여 중요한 데이터 들을 보호하며 다수의 접근이 발생할 경우 처리를 분산 시킬 수 있는 방법을 제시한다. 그리드 미들웨어인 글로 버스가 스토리지와 서버 상에서 CA인증을 담당하며 파일 전송을 담당하는 RFT는 스토리지의 Replica를 관리하는 RLS서버의 정보를 사용 하여 멀리 떨어져 있는 복제된 데이터와의 관계를 기억하고 접근시 가장 가용성이 뛰어난 머신에서 데이터를 불러온다. 이런 글로버스의 서비스 들은 중요하며 고용량이 데이터를 분산 시킴으로써 데이터의 지역성을 높여 재사용 혹은 동시 접근시 처리 시간을 단축 시킬 수 있다. 본 논문은 그리드 환경을 접목하여 이러한 서비스를 구현할 경우 높은 신뢰성과 접근의 신속성을 보장할 수 있다고 제시한다.
