In this paper, we proposed a three-dimensional visualization system for medical images in augmented reality based on deep learning. In the proposed system, the artificial neural network model performed fully automatic segmentation of the region of lung and pulmonary nodule from chest CT images. After applying the three-dimensional volume rendering method to the segmented images, it was visualized in augmented reality devices. As a result of the experiment, when nodules were present in the region of lung, it could be easily distinguished with the naked eye. Also, the location and shape of the lesions were intuitively confirmed. The evaluation was accomplished by comparing automated segmentation results of the test dataset to the manual segmented image. Through the evaluation of the segmentation model, we obtained the region of lung DSC (Dice Similarity Coefficient) of 98.77%, precision of 98.45%, recall of 99.10%. And the region of pulmonary nodule DSC of 91.88%, precision of 93.05%, recall of 90.94%. If this proposed system will be applied in medical fields such as medical practice and medical education, it is expected that it can contribute to custom organ modeling, lesion analysis, and surgical education and training of patients.

With the introduction of national health insurance, the burden of health care costs decreased and choices of medical services widened. However, because of the rapid expansion of non-covered medical services by health insurance, financial security for health care expenditure is still low. This gives patients barriers to choose medical services especially for non-covered medical services, and it becomes narrower. Compared to Korea, Japan has high financial protection in health care utilization, but there exists a limitation using covered and non-covered medical services both together. This is called a prohibition of mixed treatment in health care. This study reviews the Japanese health care system that limits choosing medical services and the burden of health care costs. The prohibition of mixed treatment can alleviate the out-of-pocket burden in the non-benefit sector, but it can be found that it has a huge limitation in that it places restrictions on choices for both healthcare professionals and patients.

For efficient compatible system between medical clinics, the medical information has to be built on a standardized protocol such as a HL7 for text data and a DICOM for image data. But it is difficult to exchange information between medical clinics because the systems and softwares are different and also a structure of data and a type of code. Therefore we analyze a structure of DICOM file and design an integrated database for effective information sharing and exchange. The WISD system suggested in this paper separate the DICOM file transmitted by medical clinics to text data and image data and store it in the integrated DB(database) by standardized protocol respectively. It is very efficient that each medical clinic can search and exchange information by web browser using the suggested system. The WISD system can not only search and control of image data and patient information through integrated database and internet, but share medical information without extra charge like construction of new system.

The u-Healthcare system, a new paradigm, provides healthcare and medical service anytime, anywhere in daily life using wired and wireless networks. It only doesn't reach u-Hospital at home, to manage efficient personal health in fitness space, it is essential to feedback process through measuring and analyzing a personal vital signs. MBAN(Medical Body Area Network) is a core of this technology. MBAN, a new paradigm of the u-Healthcare system, can provide healthcare and medical service anytime, anywhere on real time in daily life using u-sensor networks. In this paper, an ontology-based context-awareness in MBAN proposed system development methodology. Accordingly, ontology-based context awareness system on MBAN to Elderly/severe patients/aged/, with measured respiratory rate/temperature/pulse and vital signs having small variables through u-sensor network in real-time, discovered abnormal signs and emergency situations which may happen to people at sleep or activity, alarmed and connected with members of a family or medical emergency alarm(Emergency Call) and 119 system to avoid sudden accidents for early detection. Therefore, We have proposed that accuracy of biological signal sensing and the confidence of ontology should be inspected.

Korean medical libraries have made interlibrary loan active under the korean medical library association since 1969, the sharing acquisition of journals has not been peformed efficiently in the absence of a bibliographic control institute. The medical library of seoul national medical university which is designated to a medical professional information center by korea education academy information developed MEDLIS linking the union catalog and interlibrary loan system and has been operating it in cooperation with the korean medical library association. Two types of questionaries were sent to 350 medical researchers and 160 medical librarians to investigate the realities of domestic and foreign medical information institutes, develop sharing systems and find a solution for sharing systems. Also, some analyses for the recent state of duplicate subscriptions, interlibrary loan, demands for system operations un the basis of the statistics of MEDLIS users were made. The result showed that medical researchers and medical librarians are affirmative for MEDLIS, users need a convenient interlibrary loan system and medical librarians agree to activate interlibrary loan. It also showed that sharing acquisition of journals seemed to be realizable for medical librarians, although there was no intention to improve the centralization of interlibrary loan among them. From the findings, a plan for sharing acquisition of journals established by the sharing acquisition committee under korea medical libraries society and national 8 local centers to play a key role in it was made. Also, a proposal for the establishment of an information center for controlling korean medical bibliographies was suggested. This system will be expected to contribute to make users to acquire materials more effectively and save the national budget.

The rapid development and distribution of information communication industry facilitates the changes of hospital administration, introducing EMR(Electronic Medical Record) instead of paper-based medical record in the medical field. The developed countries such as U.S. have established EMR system after in the middle of 1970s because the primary advantages of EMR is to store and handle vast amounts of records efficiently and increase the quality of health care. Most of health organizations in Korea also apply medical record system to their administration. As the result, they have accomplished a scientific administration system through the use of medical record to handle a variety of patient's information including patient's confidentiality and privacy such as family history, social status, income level, and so on. However, access to and the misuse of EMR causes illegal infringement of patient's information and finally it becomes a very serious medical issue. Potential leakage and misuse of records may seriously infringe patient's privacy rights. In this respect, the related agencies in the public and private sector have been making efforts to prevent patient's records leakages. Especially, the revision bill of Medical Law in 2002 establishes the ways on the security and standards of electronic records. However, it does not provide the proper guidelines which is applied to the rapid changes of the medical environment. One of the most priorities in the hospital administration is the production and maintenance of an accurate medical records fulfilled by medical recorders. Therefore, it is very important for health care providers to hire ethical-based medical recorders. But, unfortunately most of hospitals overlook the importance of their roles. All parts including government, physician and patient must have more concerns on the problems related to EMR. Therefore, this study aims to propose the proper ways to resolve the problems coming from EMR.

The purpose of this study was to provide the basic data for improvement of Emergency Medical Service System in Kwangju. The EMSS can be defined as the complete chain of human and physical resources that provides patient care in cases of sudden illness and injury. To provide effective emergency care through the EMSS in a region, the issue of training especially as it relates to EMT in EMSS delivery is more important than emergency medical equipment and facilities for pre-hospital emergency care. The transport of emergency medical patients carried out almost by 119 Emergency Medical Services. But out of all the employees at 119 EMS only 19.0% have graduated with a major in Emergency Medical Technology. It would seem prudent then that the graduates of EMT programs should gradually replace employees working at 119 EMS that do not have an EMT degree to ensure the best possible pre-hospital care for emergency medical patients. Therefore it can be expected that in the future there should an enormous demand for qualified EMT professionals to meet the growing needs for a superior level of emergency medical care for civilian.
