RESUMO
Objective To design and implement a planning backup and restore system and evaluate its clinical effectiveness.Methods The default TPS menu of data save (File-Save) and system exit (File -Exit) was replaced by user designed script (Script_Save and Script_Exit) which backup the current planning status in a special format besides performing the normal save and exit operation.The treatment plan can be rolled back to any previously saved backup status in case the data were damaged or,the plan quality was deteriorated in the try and error planning process.Results The save and exit operation was simplified by using the user designed script.An extra disk space of 59.4MB per patient was required to backup the planning process and the backup was performed with no impact to the normal planning operation.1.9％ of the plans were restored during the planning process.For all of the restoring operations,65％ were performed within 1 day,80％ were performed within 1 week,and 87.6％ were performed within 1 month.Some restoring operations were even performed 4 months after the planning.Conclusions The designed backup and restore system is clinical applicable and valuable.Clinical using of the system can improve the planning efficiency and patient data safety.

RESUMO
There are many options on the No.1 Military Medical Project database backup in the Hospital Information System.The DataGuard of Oracle8i is one of them.This article introduces the concepts and principles of DataGuard,and briefly describes the implementation procedure and some attention-deserved problems.DataGuard is compared with traditional method for data back-up,especially the important improvement based on Oracle7 and Standby.
RESUMO
Objective To design a disaster recovery scheme for hospital information system. Methods The data disaster recovery and applied disaster recovery for hospital information system are realized by using the redundancy backup technology, active -standby technology, cluster technology and load balance technology. Results The continuity of the business is assured. Conclusion The reliability and the usability are increased.
RESUMO
Objective To construct a safe data-back-up system with disaster-tolerant ability. Methods Based on the concept of data back -up, the paper puts forward several data back -up modes in common use, and carries out corresponding comparison. Results The author synthesized these back -up modes into an ideal, feasible, and highly secure system architecture with disaster-tolerant ability. Conclusion Constructing a safe data-back-up system are becoming the mostly indispensable elements for the hospital informationization. It can avoid the single fault in the hardware level, and also can repair the logical data fault in the software level.
RESUMO
This paper introduces the backup and recovery of ORACLE database in HIS from the aspects of ORACLE setup, logical backup and recovery as well as physical backup and recovery. With the experience of the 175th hospital as an example, the method for the design and realization of the backup is put forward.
RESUMO
Objective To introduce Ghost software working principle, features and the application in medical engineering field. Methods Through the examples of Ghost software's application in the medical engineering under the single computer, the network environment, and computerized medical instrument can be proved the Ghost software's functions, features and advantages. Results In the medical engineering computer system maintenance, the Ghost software has the features of restore completely, high reliability and so on, and also the prominent advantages of convenient, flexible, quickly-operation, time -saving, high effective, economic, practical etc. Conclusion The Ghost software's application in the medical engineering field computer system is worth to exchange and expand.
RESUMO
The purpose of this research which, surveyed target hospitals, was to evaluate job operations by surveying the influences of Quality Improvement (QI) activities in various divisions related to a decrease in their back-up orders. Statistical data analyses were completed using the SPSS 11.0 program. The results can be summarized as follows : Before QI there were 147 cases of back-up orders ; after QI there were 83 cases, decrease of 64 cases. This was 44%, less than the projected goal of 50%. For each item, there was a decrease of 40 nurse cases, 9 patients and patron cases, 9 test.surgery. deliverly cases and 5 doctor cases after QI. The registering of midnight meals was not shown after QI, due to the Order Communication System (OCS) settlement. After performing QI, the average manual operation per month was reduced from 840 minutes to 498 minutes, of which the difference was 342 minutes, and the average of 342 minutes per month could be used for the peculiar operation of each division. This QI activity provided a good opportunity for establishing cooperation among divisions in providing meals to patients through interactions among divisions. It was recognized that these interactions were effective only when medical services were achieved through organized cooperation among divisions. Among the 7 items included on the patient satisfaction questionnaire, "satisfaction with offered menus" (p < 0.01) showed significantly higher scores before QI. However "satisfaction with meal times" (p < 0.01) showed significantly lower scores before QI.

RESUMO
Objective To discuss the influence of Open resetlogs on Oracle database recovery. Methods Database backup was used to recover database before resetlogs. Before Oracle 9i, Oracle database was recovered through two steps; after Oracle10g, Oracle archived redo log by new format. Results Both methods could recover Oracle database by using backups before resetlogs. Conclusion Before Oracle9i, the recovery steps are complex, so it is suggested a consistent database backup should be made after resetlogs. By using the new archived redo log format after Oracle10g, it is easy to recover database through resetlogs.
