보건의료서비스는 스마트 시대의 도래와 함께 의료와 복지, 안전 등이 복합화 되고 지능화된 스마트헬스(s-Health)의 단계로 진화되고 있으며, 향후 이용자 중심으로 다양한 서비스가 상호 연계되는 고도로 지능화되고 종합화되는 서비스로 지속적인 발전이 예상되고 있다. 따라서 PHR(Personal Health Record)서비스의 활성화를 위해서는 PHR 공동 활용 체계를 구축하기 위한 Open Platform이 필요하다. 본 논문에서는 IHE XDS 프로파일 기반의 진료정보교류 환경에서 PHR 공동 활용 체계 구축을 위하여 Mobile PHR Store를 개발하고 open API 기반 PHR Platform을 제시한다.

R has become a popular analytics platform as it provides powerful analytic functions as well as visualizations. However, it has a weakness in which scalability is limited. As an alternative, the RHadoop package facilitates distributed processing of R programs under the Hadoop platform. This paper investigates usefulness of the RHadoop package when analyzing healthcare big data that is widely open in the internet space. To do this, this paper has compared analytic performances of R and RHadoop using the medical treatment records of year 2015 provided by National Health Insurance Service. The result shows that RHadoop effectively enhances processing performance of healthcare big data compared with R.

The market for smart phones has been booming in the past few years. There are now over 400,000 applications on the Android market. Over 10 billion Android applications have been downloaded from the Android market. Due to the Android popularity, there are now a large number of malicious vendors targeting the platform. Many honest end users are being successfully hacked on a regular basis. In this work, a cloud based reputation security model has been proposed as a solution which greatly mitigates the malicious attacks targeting the Android market. Our security solution takes advantage of the fact that each application in the android platform is assigned a unique user id (UID). Our solution stores the reputation of Android applications in an anti-malware providers' cloud (AM Cloud). The experimental results witness that the proposed model could well identify the reputation index of a given application and hence its potential of being risky or not.

Mixed reality technology (MR) has become one of the fourth industrial revolution element technologies. MR technology has been widely applied not only as a digital contents industry but also in the fields of architecture, tourism, medical field, and education. In this paper, we propose a collaborative service platform for architectural applications that inter-operate with heterogeneous devices such as MR device, PC and mobile, and develop prototype system and verify it. As a result, the 3D model using the skp extension, which is mainly used in architecture design office, was created by using developed prototype system and generate the MR contents for the hololens, which is the MR device, and the conversion time and normal operation were confirmed.

Recently, IoT technologies attract much attenction in medical area. Previous medical IoT had focused mainly on chronological diseases or fitness for particular users. Contrarily, medical use of the IoT technologies is now extended for medical institutes and hospitals to care intensively in-house patients, which requires typically more strict and reliable data delivery and security, authentication and authorization. This study defines scenario of the medical IoT for the intensive care and proposes an architecture of the medical IoT services. We implement a testbed using commerical sensors and Arduino board together with a Web-based platform. Experiment results on the testbed show that our approach can be feasible for the medical system in terms of latency and accuracy in medical data delivery.

인공지능 기술을 도입한 의료분야에서 진단 및 예측과 연계한 임상의사결정지원 시스템(CDSS)에 관련된 연구가 활발하게 진행되고 있다. 특히, 인공지능 기술 적용에 가장 많은 이슈를 일으키고 있는 의료영상기반의 질환진단연구가 다양한 제품으로 출시되고 있는 실정이다. 그러나 의료영상 데이터는 일관되지 않은 데이터들로 이루어져 있으며, 그것을 정제하여 연구에 사용하기 위해서는 상당한 시간이 필요한 것이 현실이다. 본 논문에서는 익명화된 데이터를 정제하여 인공지능 연구에 사용할 수 있는 표준화된 데이터 셋을 만들고, 그 데이터를 기반으로 인공지능 알고리즘 개발 연구를 지원하기 위한 원스톱 인공지능학습 플랫폼에 대하여 기술한다. 이를 위해 전체 인공지능 연구프로세스를 보이고 이에 따라 학습을 위한 데이터셋 생성과 인공지능 학습학습용 플랫폼에서 수행되는 수행 과정을 결과로 보인다 제안한 플랫폼을 통해 다양한 영상기반 인공지능 연구에 활용될 것으로 기대하고 있다.

의료산업은 진단 및 치료 위주의 기술개발이 진행되어왔다. 최근 의료 빅데이터를 기반으로 진단, 치료 및 재활뿐만 아니라 예방과 예후관리까지 지원하는 의료서비스에 대한 패러다임이 변화되고 있다. 특히, 여러 의료 중심의 플랫폼 기술 가운데 객관적인 진단지표를 가지고 있는 의료영상을 기반으로 인공지능 학습에 적용하여 진단 및 예측을 중심으로 한 플랫폼 개발이 진행되고 있다. 하지만, 인공지능 연구에는 많은 학습 데이터가 요구될 뿐만 아니라 학습에 적용하기 위해서는 데이터 특성에 따른 전처리 기술과 분류 작업에 많은 시간 소요되어 이와 같은 문제점을 해결할 수 있는 방법들이 요구되고 있다. 따라서, 본 논문은 인공지능 학습까지 적용하기 위한 의료영상 데이터에 대한 확장 모델을 개발하여 공통적인 조건에 따라 의료영상 데이터가 표준화되어 변환하며, 자동화 시스템 구조에 따라 데이터가 분류·저장되어 인공지능 학습까지 지원할 수 있는 플랫폼을 제안하고자 한다. 그리고 근감소증 학습데이터 관리 및 적용 결과를 통해 플랫폼의 수행성을 검증하였다. 향후 제안한 플랫폼을 통해 의료데이터에 대한 전처리, 분류, 관리까지 지원함으로써 CDM 확장 표준 의료데이터 플랫폼으로 활용 가능성을 보였다.

The market for medical tourism services in the world is steadily increasing and the medical tourism market in the South Korea is also showing high growth. However, they have also problem such as informal various information and services, irregularity price competition etc. In order to solve this problem, We have designed a medical tourism service model based on ICT specific on domestic medical ecosystem. First, analysis trends of domestic and overseas medical ecosystem and identify current problem of medical tourism. In order to solve existed problem we also have designed a medical tourism strategy. Based on the strategy, we have designed business service model based on ICT platform for as fit as Korea medical tourism status. The proposed medical tourism business service model can provide usability to customer and also can solve current medical tourism problem. We expect industrial effect and contribution to the activation.

In recent years, medical procedures have become more complex, while financial pressures for shortened hospital stays and increased efficiency in patient care have increased. As a result, several shortcomings of present film-based systems for managing medical images have become apparent. Maintaining film space is labor intensive and consumes valuable space. Because only single copies of radiological examinations exist, they are prone to being lost or misplaced, thereby consuming additional valuable time and expense. In this paper, Any-PACS for image archiving, transmission, and viewing offers a solution to these problems. Proposed Any-PACS consists of mainly four parts such as Web Module, Client-Server Module, Internal Module, Acquisition Module. In addition, Any-PACS system includes DICOM Converter that Non-DICOM file format converts standard file format. In Client-Server Module case, Proposed system is combined both SCU(Service Class Use: Client) part and SCP(Service Class provider: Server)part therefore this system provides the high resolution image processing techniques based on windows platform. Because general PACS system is too expensive for Medium and Small hospitals to install and operate the full-PACS. Also, we constructed Web Module for database connection through the WWW.

Active studies are under way on telemedicine and medical support based on mobile devices in order to vitalize U-Healthcare. Especially when the medical law is revised to allow a remote prescription system, studies on a mobile prescription system will rapidly increase. And yet since mobile apps have less compatibility due to the nature of mobile platform, there is a restriction that they have to be redeveloped to be compatible with the platform. To compensate this problem, this study designs a mobile web prescription interface by using HLTML5, the standard language of mobile web development and jQuery Mobile, a JavaScript Library. It also adds a feature of converting to a form of standard protocol HL7-based messages to share data with existing hospital information system. This interface makes it possible to be interlocked with the existing hospital information system through the transmission of the HL7 messages. The advantage of the proposed system is that it can be used in various environments since it is independent of mobile platforms and compatible with general computers.
