본 논문에서는 헬스 빅데이터 플랫폼에서 이기종 라이프로그 마이닝 모델을 제안한다. 이는 사용자의 라이프 로그를 실시간으로 수집하고 헬스케어 서비스를 제공하기 위한 온톨로지 기반의 마이닝 모델이다. 제안하는 방법은 이기종 라이프 로그 데이터를 분산처리하고, 클라우드 컴퓨팅 환경에서 실시간으로 처리한다. 이를 이기종 온톨로지를 기반으로 구성한 환경에 적합하도록 상위 온톨로지 방식으로 지식베이스를 재구성한다. 재구성한 지식베이스는 Jena 4.0 추론엔진을 이용해 추론 규칙들을 생성하고, 규칙 기반 추론 방법으로 실시간 헬스 서비스를 제공한다. 라이프로그 마이닝을 숨겨진 관계에 대한 분석과 시계열적 생체신호에 대한 예측모델을 구성한다. 이는 관계나 추론규칙에서 포함되지 않은 음의 상관관계나 양의 상관관계를 탐색하여 사용자의 생체신호에 대한 변화를 감지하고 예방 의료 서비스를 현실화하는 실시간 헬스케어 서비스가 가능하다. 성능 평가는 제안한 이기종 라이프로그 마이닝 모델 방법이 정확도에서 0.734, 재현율에서 0.752로 다른 모델에 비해 우수하게 나타난다.

최근 병원정보 시스템은 의료서비스의 질과 효율성을 제고하기 위해 스마트폰 및 태블릿 PC를 활용한 스마트 진료서비스가 대형병원을 중심으로 도입되고 있으며 개인의 진료정보를 PC, 스마트폰 등을 통해 관리하는 개인건강기록(PHR) 서비스에 대한 관심 및 기술개발이 활발히 진행 중에 있다. 이러한 차세대 병원정보 시스템을 구축하기 위해서는 상이한 병원정보 시스템 간의 데이터 연동과 다양한 사용자 기기 간의 UX 일관성이 보장되어야 한다. 따라서 본 논문에서는 이러한 멀티플랫폼 환경 하에서 의료정보를 통합하여 연동할 수 있는 게이트웨이 시스템을 설계하기 위해 개인의 진료정보 표준과 성능 향상을 위한 연구를 수행하였다. 본 연구를 통해 게이트웨이 시스템의 핵심 기능인 데이터 간의 매핑 방법에 있어서 CCR 표준을 적용하고 다중 테이블 기반 매핑 방법을 사용하여 시스템 설계를 하였다. 이에 대한 성능 평가를 위해 실험을 한 결과 응답속도가 약 20% 향상된 결과를 얻을 수 있었다.

In the conduct of this study, a web-enabled healthcare system for the management of hypertension was implemented through a hyperlink-based inference approach. The hyperlink-based inference platform implemented using the hypertext capacity of HTML which ensured accessibility, multimedia facilities, fast response, stability, ease of use and upgrade, and platform independency of expert systems. Many HTML documents, which are hyperlinked to each other based on expert rules, were uploaded beforehand to perform the hyperlink-based inference. The HTML documents were uploaded and maintained automatically by our proprietary tool called the Web-Based inference System (WeBIS) that supports a graphical user interface (GUI) for the input and edit of decision graphs. Nevertheless, the editing task of the decision graph using the GUI tool is a time consuming and tedious chore when the knowledge engineer must perform it manually. Accordingly, this research implemented an automatic generator of the decision graph for the management of hypertension. As a result, this research suggests a methodology for the development of Web-enabled healthcare systems using the hyperlink-based inference approach and, as an example, implements a Web-enabled healthcare system for hypertension, a platform which peformed especially well in the areas of speed and stability.

With the recent change of healthcare environment including rapid technological development, evidences are more and more important and necessary to support relevant policies in health technology assessment to provide safe and effective health services, utilizing medical resources efficiently. Despite of the emphasis on the importance of real world data and real world evidence in health care research, current infrastructure supporting clinical research is considerably weak due to absence of legal and institutional basis. However, in accordance with the Article 26 of the Health and Medical Technology Promotion Act, there is a limited legal apparatus that can be used only in public data with other dataset for the purpose of healthcare technology assessment at the National Evidence-based Collaborating Agency. Although the use of linked data from various sources was often required in the field of clinical research, it was not yet working well due to insufficient environmental conditions. In order to support the decision-making of medical practice and health care policies, data-linking platform for clinical research is needed. If the legal system that can link up to the data of the private institutions without violating the significant value such as the protection of private informations is established, it will be a decisive foundation reinforcing the researches and policy making processes for the improvement of the national health care system.

Purpose: This study aimed to investigate the maternal health effects of internet-based education interventions on parturients during the postpartum period through a systematic review of randomized controlled trials. Methods: An electronic literature search of the Cochrane Library, CINAHL, EMBASE, Eric, PsycINFO, PubMed, RISS, and KISS databases was performed, using the combination of keywords such as 'parenthood education', '*natal education', '*birth intervention', 'internet-based intervention', 'randomized controlled trial'. The inclusion criteria were peer-reviewed papers in English regarding randomized controlled trials of internet-based postnatal education interventions. Educational interventions were delivered through any web, mobile, eHealth, mHealth, virtual reality, short message service, or social networking service platform. Quality appraisal was performed using the Risk of Bias 2 (RoB 2) for randomized controlled trials. Nine articles were yielded, and the intervention effects were analyzed. Results: Internet-based education interventions during the postpartum period affect maternal self-efficacy, postpartum depression, and successive breastfeeding; however, they do not affect maternal satisfaction and parenting confidence. Conclusion: This study demonstrated that internet-based education interventions affect maternal health status in terms of psychological, emotional, and physical wellness. Therefore, maternal health care professionals can utilize remote education using the internet or mobile-based interventions during the postpartum period.

The purpose of this study was to investigate the effects of the task-oriented training according to the application time with the change of motor and cognition function. Focal ischemic brain injury was produced in Sprague-Dawley rats (20 rats, $250{\pm}50$ g) through middle cerebral artery occlusion (MCAo). Before MCAo induction, all rats were trained in treadmill training and Morris water maze training for 1 week. Then they were randomly divided into groups: Group I : MCAo induction ($n_1$=5), Grop II: the application for simple treadmill task training after. MCAo induction ($n_2$=5). Group III: the application for Morris water maze cognitive task training after MCAo induction ($n_3$=5). Group IV: the application for progressive treadmill task training and Morris water maze cognitive task training after MCAo induction ($n_4$=5). Modified limb placing tests (MLPTs) and motor tests (MTs) were performed to test motor function and then Morris water maze acquisition test (MWMAT) and Morris water maze retention test (MWMRT) were performed to test cognitive function. For MTs, there were significant interactions among the groups with the time (p<.001). Group IV showed the steeper increasing pattern than those in other Groups on the 7th and 14th day. For MLPTs, there were significant interactions among the groups with the time (p<.001). The scores in Group III. IV had showed the more decreasing pattern than those in Group I, II since the 7th day and 14th day. For MWMAT, there were significant interactions among the groups with the time (p<.001). Group II found the Quadrant circular platform showed the steeper decreasing pattern than that in Group I on the 9th, 10th, 11th and 12th day. Group III. IV found the quadrant circular platform showed the slower decreasing pattern than that in Group I, II, For MWMRT, there were significant differences among the four groups (p<.001). The time to dwell on quadrant circular platform in Group IV on the 13th day was the longest compared with other groups. These results suggested that the combined task training was very effective to improve the motor and cognition function for the rats affected on their focal ischemic brain injury.

Down through the years, human needs and desires have required a robot system to work at hazardous environments instead. Current painting task is costly and laborious, and it exposes workers to significant health and safety risks. Automation system offers potential improvement in this area and is especially well suited to the outer-wall painting tasks in concrete structures. This paper introduces the result of gondola-type building management robot(G-BMR) platform and mechanism for moving/tasking on building outer-wall for the outer-wall painting. Its technical and economic feasibility are conducted, and it is concluded that developing G-BMR is physically and economically feasible in this research. And we discuss about the future of G-BMR and automation in construction field.

There are many researches to build up ubiquitous environment by the Ubiquitous Sensor Network(USN). These applications, such as home network, health care, natural environment and agricultural areas, are implemented by an embedded system. Their fields are gradually spreading. However the power consumption in its implementation plays an important role on the surrounding environment of the wireless network. In this paper, we design low power processor based sensor node platform for agricultural applications. We also compare its some performance with existing products.
