IEC 62304 is a standard for the medical device software lifecycle. Developers must develop software that complies with all specifications in the standard for licensing. However, because the standard contains not only a large number of specifications, but also domain-specific information and association relationships between specifications, it requires considerable effort and time for developers to understand and interpret the standard. To support developers, this paper presents a method for extracting the contents of the IEC 62304 standard as a goal model, which is the core methodologies of requirements engineering. The proposed method analyzes the grammar of the standard to robustly extract complex structures and various information from standard specifications and define rules that extract goals and links from syntactic element units. We validated the actual extraction process for the standard document experimentally. Based on the extracted goal model, developers can intuitively and efficiently comply with the standard and track specific information within the medical software and standard domains.

A controlled medical vocabulary is a vital component of medical information management because it enables computers to use information meaningfully and different institutions to share the medical data. There are currently many standard medical vocabularies - SNOMED-CT, ICD-10, UMLS, GALEN, MED, etc, but none is universally accepted as an optimal controlled medical vocabulary for application to medical information system. Moreover, it is difficult to settle the well-designed local data dictionary consisting of controlled medical vocabularies for the individual hospital information system (HIS). One of the major reasons is the local terminology with poor contents have been used in the hospital. Thus, as a trial, the local controlled vocabulary referencing system has being constructed in a limited medical field - nuclear medicine. We selected practical nuclear medicine terms from interpretation reports and electronic medical records, and removed ambiguity and redundancy, mapping the selected terms to standard medical vocabularies. Relationship and hierarchy structure between terms have being made, referring to standard medical vocabularies. Further studies may be warranted.

As the adoption of PACS and hospital information system among university hospitals and hospital level institutions grows bigger, the need of sharing and transferring medical information among medical institutions is rising. For the medical information, which is saved in the hospital medical system, to be transferred within the same hospital, domestic, or foreign medical institutions, a standard protocol is necessary. But realistically, most of the domestic hospitals do not abide by H7L which is the HIS standard and so, information transferring is not possible as of present. As such, the purpose of this research is to implement the information between HIS and PACS to an international standard by constructing HL7 messages through HL7 Interface. which will eventually make possible information transferring between different hospitals. Our research team has developed a method which will make the PACS equip hospitals that do not follow HL7 standard which will make possible to transfer information between HIS and PACS through HL7 Message. By constructing message files, which follow the form of HL7 Message in the HL7 Interface, they can be transferred to PACS through the ftp protocol. The realization of the HIS/OCS Interface through HL7 enables data transferring between domestic and foreign medical institutions possible by implementing the international standard in the PACS and HIS data transferring process. The HL7 that our research team has developed made patient data transfer between medical institutions possible. The Interface is for a specific system model and in order for the data transfer between different systems to be realized, interfaces that are fit for each system must be needed. If the interface is improvised and implemented to each hospital's information system, the data sharing among medical institutions can be broadened.

U-healthcare 시스템은 예방, 진단, 의료관리 등 현재 다양한 의료서비스시스템에 활용되고 있다. 그러므로 병원, 의료센터 등에서 이러한 의료정보의 활용은 필수적이다. 그러나 의료정보 표준인 HL7은 현재 표준화된 의료정보 명세로 지원되지 못하고 있는 실정이다. 따라서, 이 논문에서는 HL7을 의료정보표준화와 효율적인 의료정보활용을 위해 연구, 분석하였으며 그 효과성을 확인하였다.

Objective : To poll oriental medical doctors on their opinions about the necessity of standard medical charts and of detailed items in their development. Currently, oriental medical institutions use their own medical charts, but a standard medical chart is necessary for medical information sharing. Methods : Report by 912 of the 10,490 oriental medical doctors surveyed on their general aspects, actual conditions, and requirements. Results : The oriental medical doctors surveyed who worked in oriental medicine clinics, oriental medicine hospitals, and public health centers said medical examination programs should consist of chief complaints (said by 814 respondents or 89.25%), history (792 or 86.84%), ordinal symptoms (753 or 82.57%), diet (727 or 79.71%), emotions and overstrain (654 or 71.71%), side effects and allergies (622 or 68.20%), improvement of symptoms (605 or 66.34%), a questionnaire on particular diseases (558 or 61.18%), social aspects (523 or 57.35%), a physical examination (520 or 57.02%), a questionnaire on syndrome differentiation (514 or 56.36%), diagnosis using medical devices and laboratory tests (471 or 51.64%), and Sasang constitution (357 or 39.14%). Ninety-one percent of the respondents said they intended to use a standard chart, and 82.19% agreed to share patient information with medical institutions. Conclusions : Over 90 percent of the oriental medical doctors surveyed said they need a standard medical examination program. Oriental medical examination items that correspond with the opinions of the oriental medical doctors surveyed and of experts will thus be developed, and the draft chart will be distributed to oriental medical institutions with the developed medical forms and electronic medical chart.

The safety and performance of medical device software is managed through life-cycle processes, which represent the entire process of research and development (R&D). The life-cycle process of medical device software is represented by an international standard called IEC 62304, ISO/IEC 12207. In order to license the product, the manufacturer must have document artifacts that comply with the IEC 62304 standard. However, these standards only describe the content of the activity and do not provide a method or procedure for documentation. Therefore, this paper suggests R&D documentation guidelines that assist medical device software developers to have R&D documents conforming to the standards. For this purpose, this study identifies the requirements related to documentation among the requirements existing in the standard and extracts them in the form of guidelines showing only the core information of the requirements. In addition, through the Web framework implemented based on this research, the developer can evaluate whether the technical documents are written in accordance with the R&D document guidelines. Medical device software manufacturers can efficiently produce high-quality research and development documents through R&D documentation guidelines, and they can have standards-compliantresearch and development documentation required for licensing procedures.

대역폭과 저장장치의 한계 때문에 의료영상은 전송과 저장 전에 압축되어야 한다. 의료영상 표준인 DICOM(Digital Imaging and Communications in Medicine)은 JPEG 정지영상 압축을 지원하는 구조를 제공한다. 본 논문에서는 의료영상을 JPEG으로 압축하기 위한 방법을 설명하고 JPEG 압축을 위한 두 가지 방법을 제안한다. 첫 번째로 의료영상은 자연영상과는 시각적인 특성이 다르기 때문에, 스펙트럼 분석을 이용한 양자화 테이블을 적응적으로 설계하는 방법을 제안한다. 두 번째로 의료영상은 자연영상과 다르게 픽셀당 비트수가 높기 때문에, 심벌들의 확률분포 특성을 고려한 허프만 테이블을 적응적으로 설계하는 방법을 제안한다. 따라서 본 논문에서는 의료영상에 적합한 양자화 테이블과 허프만 테이블을 설계하는 방법을 제안한다. 실험 결과 JPEG 표준의 양자화 테이블과 수정된 허프만 테이블에 비해 성능이 향상되는 것을 볼 수 있다. 본 논문에서 제안한 방법은 JPEG 표준을 만족하므로, PACS (Picture Archiving and Communications System)에 적용될 수 있다.
