The size and speed of archives and records information have recently increased. The purpose of this study is to find the direction of archives management research in Korea through an in-depth analysis of research trends in records management in the country. We collected articles related to archives management from 1997 to 2016 from two journals related to archives management and four journals related to library and information science in Korea. The collected articles from the first and second halves of the decade were subjected to five-year cycle analysis. As a result, research on electronic records, record information services, and archiving methods of various records has been gradually improved.

Information concerning a patient visit is to be sent from the OCS(Order Communication System) to the PACS(Picture archiving and Communication System) and when the image acquisition is completed, information regarding the procedures also actually preformed should be sent back to the OCS. It should be possible to present related medical information from the OCS at the same image workstation in a coherent way with the images in the PACS, Examples of the related medical information are: the report of a diagnostic image procedure, data on medication, laboratory results, admission and discharge letters, and surgery reports, because we could maximize the efficiency of Radiological Work, like decrease examination time and human mistakes, though the integration of PACS and OCS, Therefore, We research some hospitals to find integral lists of PACS and OCS but there are no sufficient ingredients. Further, the percentage of Integral lists of PACS and OCS is different in all hospitals because there is no such standard yet like HL7(Healthcare Level 7) and DICOM(Digital Imaging and Communications in Medicine). Accordingly, if all hospital would follow national standard like HL7 and DICOM, the integration of OCS and PACS would be efficient but in this situation radiological technician should take part in construction integration system of PACS and OCS positively, so we could improve efficiency of radiological work and our status.

To compare the accuracy of breath-hold magnetic resonance imaging sequences to establish the most effective superparamagnetic iron oxide-enhanced sequence for detection of hepatic metastases. A total of 100 patients(50men and 50women, mean age: 60years) with liver disease(including malignant and benign liver lesions) were investigated at 3.0T machine (GE, General Electric Medical System, Excite HD) with 8Ch body coil. Pulse sequence for MR imaging decided to the FS-T2-FSE-RT(TR/TE/Thick./Freq./Phase=12857ms/100ms/7mm/512/384), MGRE(TR/TE/Thick./Freq./Phase=100ms/9.7ms/7mm/384/288), in-out of phase echo(TR/$TE_1$, $TE_2$/Thick./Freq./Phase=140ms/2.4, 5.8ms/7mm/352/300), Images obtained before the injection of SPIO. Six sequences were optimized for lesion detection: FS-T2-FSE-RT, multigradient recalled echo data image(MGRE), T2-weighted MGRE with an 9.7msec echo time. Images were reviewed independently by five blinded observers. The accuracy of each sequence was measured by using picture archiving communication system analysis. All results were correlated with findings at multidectator computed tomography examination. Differences between the mean results of the six observers were measured by using paired student t-test analysis. Postcontrast T2-weighted MGRE sequences were the most accurate and were significantly superior to postcontrast FS-T2-FSE-RT, T2-weighted MGRE, in-out of phase MR sequences(p < .05). For all lesions that were malignant or smaller than 1 cm, respectively, contrast to noise ratio of pre and postcontrast sequences were -1and -0.3 for T2-weighted FSE, 0.53 and 4.5 in-out of phase, 7, 7.08, 5.08, 3.32, 1.7, 1.16, 0.79, 0.68 for GRE with 2.9, 7.5, 12.1, 16.6, 21.2, 25.8, 30.4, 35.0 TE values. Breath-hold various TE precontrast sequences offer improvement in sensitivity compared with fixed multigradient recalled echo sequences alone.

The recent development of embodiment technology of the medical images makes most medical institutions introduce PACS in haste. However, while many older HIS and PACS systems are not yet capable of some of the integration, several new systems are moving rapidly in that direction. Typical PACS system architecture begins with the HIS since this is where the correct patient demographic information and in many cases the orders originate. So, PACS developed convenience of users and to satisfy user's demand because of financial limitations and administrator-oriented considerations in the process of development. Therefore, we have developed a CDA (Clinical Document Architecture) based PACS with HIS, by which we can search and refer to the patient's medical images and information with few restrictions of time and space for diagnosis and treatment. Target model of this research limited to 135 of hospital have 200 beds. We'll make more effort to develop the application which insures the better quality and information of medical images. Medical Image History manages the patient's image files and various medical informations like film chart in connection with time. This trial will contribute to the reduction of the financial loss caused by unnecessary devices and improve the quality in the medical services. The demand on the development of the program which refers to the medical data quickly and keeps them stable will be continued by the medical institute. This will satisfy the client's demand and improve the service to the patients in that the program will be modified from the standpoint of the users.

In this paper, we propose an effective coding method of the angiography by using the scalable structure in the frequency domain for MPACS(Medical Picture Archiving and Communication System). We employed the subband decomposition method and MPEG-2 system which is the international standard coding method of the general moving picture. After the subband decomposition is applied to split an input image into 4 bands in the spatial frequency domain, the motion compensated DPCM coding method of MPEG-2 is carried out for each subband. As a result, an easily controllable coding Structure is accomplished by composing the compound hit stream for each subband group. Follows are the simulation results of the proposed sheme for the angiography. A scalable structure which can be easily controlled for a loss of transmission or the band limit can be accomplisbed in the MPEG-2 stucture by the subband decomposition minimizing the side information. And by reducing the search area of the motion vector between -4 and 3, the processing speed of a codec is enhanced by more than two times without a loss of the picture quality compare with the conventional DCT coefficients decompositon method. And the processing speed is considerably improved in the case of the parallel construction of each subband in the hardware.

In future, hospitals are expected to automatically issue remote transcriptions. Many general hospitals are planning to encrypt their medical database to secure personal information as mandated by law. The electronic medical record system, picture archiving communication system, and the clinical data warehouse, amongst others, are the preferred targets for which stronger security is planned. In the near future, medical systems can be assumed to be automated and connected to remote locations, such as rural areas, and islands. Connecting patients who are in remote locations to medical complexes that are usually based in larger cities requires not only automatic processing, but also a certain amount of security in terms of medical data that is of a sensitive and critical nature. Unauthorized access to patients' transcription data could result in the data being modified, with possible lethal results. Hence, personal and sensitive data on telemedicine and medical information systems should be encrypted to protect patients from these risks. Login passwords, personal identification information, and biological information should similarly be protected in a systematic way. This paper proposes the use of electronic acupuncture with a built-in multi-pad, which has the advantage of being able to establish a patient's physical condition, while simultaneously treating the patient with acupuncture. This system implements a sensing pad, amplifier, a small signal drive circuit, and a digital signal processing system, while the use of a built-in fuzzy technique and a control algorithm have been proposed for performing analyses.

The government and public institutions are conducting public-opinion surveys as means of drawing the scientific policy decisions throughout the country's whole sectors ; society, culture, welfare, education, etc. The Government Survey Data have been under management by each governmental department, but the improper ways of data collection and management have led to omissions and losses of some data. Also there are limitations on the statistic usage and access to the data due to the fact that the data are managed dispersedly in the form of printed materials. Accordingly, to make the survey data available for the long-term preservation and usage, this study suggests collection policy, standard of evaluation, metadata, the procedure and method of converting materials, preservation format.

This study suggested a digital curation framework for supporting the digital policy of institutes that collect memory. As such, it conducted a literature review and an analysis of digital curation models, as well as a focus-group interview of historians and graduate students majoring in historical studies. In this study, digital curation framework refers to an abstract model for supporting policy development and the planning for a high-level view of the archival information service. This implications of this framework are as follows: (1) to emphasize the data life cycle and connection between stages and actions; (2) to make an infra-schema for understanding institutes that create, arrange, or store specific data as the same history contents have to be provided by different institutes and as there are differences in the data's value; (3) to check the present conditions of information services and their systems; (4) to consider the practical applications of contents that have been collected and stored; and (5) to converge all data in one system through the framework and activate diverse works in the context of the framework.

Because archaeological artifacts are often destroyed during physical excavation, the data archaeologists gather in the field is rich with research potential. Few in Korea have paid attention to digital archives for archaeological data or argued for their development. This paper considers the significance and necessity of archaeological data and digital archives for its preservation and access. It also raises awareness of the need to develop a Korean national archaeological data digital archive. The paper first overviews the nature of the archaeological discipline, data, and digital archives. Then it investigates well-known, global cases involving digital archiving of archaeological data. Based on these foundations, the paper discusses principal and prior challenges to developing a Korean national archaeological data digital archive.
