The mobile terminal system plays a key role in medical industries which require in fast and accurate diagnosis from heterogeneous acquisition equipment. The demand for PACS (picture archiving and communication systems) has continued to increase in major hospitals and private clinics. Patient care depends on how fast the medical imaging system provides images and how accurately the images are interpreted by physicians. In this paper, we propose an efficient method to decipher the hundreds of images required by physicians to accurately diagnose patients. By exploring Motion- JPEG (M-JPEG), this paper has demonstrates the possibilities for efficient management of medical images with a newly designed image file format and improvement in imaging diagnoses through the replaying of moving pictures of a patient in a mobile environment.

Objectives: This study aimed to assess the validity of 'Korean Diagnosis Related Groups-Korean Medicine (KDRG-KM)' which was developed by Health Insurance Review & Assessment Service (HIRA) in 2013 Methods: Among inpatient EDI claim data issued by hospitals and clinics in 2012, the data which included Korean medicine procedures were selected and analyzed. We selected control targets in the Korean medicine hospitals which had longer Episodes-Costliness index (ECI) and Lengthiness index (LI) than average of total Korean medicine hospitals, and compared the results of selection between the major diagnosis-based patient classification system and the KDRG-KM system. Finally, the explanation power (R2) and coefficient of variation (CV) of the KDRG-KM system using practice expenses were calculated. Results: The numbers of control target in Korean medicine hospitals changed from 36 to 32 when patient grouping adjustment method was changed from major diagnosis to KDRG-KM. For expenses of all outpatient claim data on Korean medicine, explanation power of KDRG-KM system was 66.48% after excluding outliers. CVs of expenses of patient groups in Korean medicine hospitals were gathered from under 70% to under 90%, and those in long-term care hospitals mostly belonged under 70%. Conclusions: The validity of KDRG-KM system was assured in terms of explanation power. By adapting KDRG-KM system, fairness of control targets selection for costliness management in Korean medicine hospitals can be enhanced.

U-healthcare is real-time monitoring of personal biometric information using by portable devices, home network and information and communication technology based healthcare systems, and fused together automatically to overcome the constraints of time and space are connected with hospitals and doctors. As u-healthcare gives health service in anytime and anywhere, it becomes to be a new type of medical services in patients management and disease prevention. In this paper, recent changes in prevention-oriented care is analyzed in becoming early response for Healthcare Information System by requirements analysis for technology development trend. According to the healthcare system, PACS, OCS, EMR and emergency medical system, U-healthcare is presenting the design of a patient-centered integrated client system. As the relationship between the meaning of the terms is used in the ontology, information models in the system is providing a common vocabulary with various levels of formality. In this paper, we propose an ontology-based system for patient-centered services, including the concept of clustering to clustering the data to define the relationship between these ontologies for more systematic data.

This study aims to develop the methods for effective managing national health screening patients in the health examination center using digital data from national health screening in Dae-Jeon health examination center. To achieve this, we collected about national health screening for 10 years from 2002 to 2011 in Dae-Jeon health examination center and developed re-examination predictive model, private examination predictive model and stomach cancer examination predictive model for national health screening patients by using this data. According to the predictive model results, age, residence, group or individual health examination and the previous number of national health screening were statistically associated with re-examination, private examination, stomach cancer examination. We came up with a plan for health examination center system based on the predictive model and logic in Dae-Jeon. Customized service based on patient management system for national health screening will contribute to efficiency in health examination center.

With the prospect of rapidly growing health insurance expenditures, particularly spending for ambulatory care, the introduction of a case-based payment method is discussed as an alternative to the current fee-for-service based method. A system to measure case mixes of providers is a core component of such payment systems. The objective of this study were to develop a classification system for ambulatory care, Korean Ambulatory Patient Group (KAPG) based on the U.S. APG version 2.0 and to evaluate the classification accuracy of the system. A database of 64,258,386 records was constructed from insurance claims submitted to the Health Insurance Review Agency (HIRA) during three months from August 2002. A total of 41,347,307 records with a single visit was used for the development and 7% random sample of the database was used for the evaluation. Additional groups were defined to include both physician and hospital fees in the classification, age splits were added to classify the entire population as well as the population older than 65, and the definition of medical groups used by the HIRA was adopted. The variance reduction in charges achieved by KAPGs was computed to evaluate the accuracy of classification. A total of 474 KAPGs was defined compare to 290 groups in the U.S. APG. The variance reduction for charges of all visits ranged from 20% to 37% depending on the type of provider, and ranged from 22% to 42% for non-outliers, that were better than those achieved by the system currently used by the .HIRA for its internal review purpose. Although further study is required to improve the classification for complicated care in larger hospitals, the results indicated that KAPGs could be used for better management of costs for ambulatory care.

A medical information management system for small to medium sized clinics and hospitals is developed. The system is designed to process, analyze and manage each patient's clinical record using database technique. The structure of the database was determined and implemented through careful and rigorous study of medical practices in Korea and, therefore, reflects the needs of information management in Korean medical community. Furthermore, a sophisticated inference engine that can deduce possible diseases from the result of medical examination is added to the system to provide doctors with a guideline in medical diagnoses.

This study identifies consumer satisfaction with medical services and the patient gowns of hospitals. Also analyzed are the elements that influence hospital satisfaction and the general satisfaction with patient gowns. A survey was conducted among Korean male and female ex-patients regardless of their age. A total of 513 responses were analyzed using descriptive statistics, paired t-test, correlations, regression, and factor analysis derived from data collected in April and May, 2009. The results are as follows. The general satisfaction with the hospital recently visited was higher than the general satisfaction with all of the hospitals visited. The satisfaction with medical services were high in good services, trustful medical examinations, easy access to utilities, and clean utilities. Hospital satisfaction was determined by good services, trustful medical examinations, easy access to utilities, patient gowns, and fresh indoor air. The satisfaction factors of general patient gowns were determined as functionality, fabric/design, sewing, and the management system factors. The most important factor explaining patient gown satisfaction was fabric/design, and this was the most unsatisfied factor at the same time.

In developing total hospital information system, large amount of time and expense are to be spent while its results are likely to lead itself to end-users' dissatisfaction. Some of the main complaints on the part of end-users come from insufficient consideration of end-users environment as well as inappropriate representation of their requirement in the system alalysis and design. This papre addresses some advantages of Essential Logical Modeling Process for better analysis and design, explaining by example the developmental process of the Patent Management and Accounting System for a tertiary care hospital. In the case, the Essential Model, suggested by McMenamin and Palmer, proved to be an effective tool for clear separation of analysis and design phase and for better communication among system developers and with end-users. The modeling process itself contributed to better program modularity as well, shown in a Structured Chart. Difficulties in learning how to identify' essential activities' for the modeling practice were experienced in the beginnins stage, which were, however, overcome by elaborating some heuristic guideling and by rdferring to necessary tools including State Transition Diagram, Control Flow Diagram, and so many. While full evaluation of the Essential Model usag remains to wait till the completion of the case project, its strengt in making clear distinction between analysis and design phase was enough to be attractive to system analysts. The model concepts are open to many further application fields, particularly such areas as business re engineering, process remodeling, office automation, and organizational restructuring.

Background: With ageing and growing importance of disease management system, it is necessary to investigate the extent of regional difference in service utilization for chronic diseases among the elderly and to reflect it in designing the system. Methods: A multiple regression analysis and descriptive statistics analyses were employed using patient survey, which covers nationwide health facilities and their users. Results: While the differences in the rate of service utilization/utilization outside living area between urban and rural areas or between income levels are not large, considerable variations are observed within urban or rural areas and within income groups. Conclusion: This results suggest that it is important to subsidize economically disadvantaged segments of the population and residents of less-favored areas to be better-equipped for chronic disease management in order to prevent the development of severe ailments and the need for treatment at higher-level medical institutions. Improvements to the service infrastructure in vulnerable regions are essential.
