This paper presents a redundantly actuated six degrees-of-freedom parallel kinematic mechanism with a partially decoupled architecture in its rotational motion. This mechanism is developed to eliminate kinematic complexity of original Eclipse-II known as a redundant parallel mechanism. Since the original Eclipse-II mechanism use kinematic redundancy of parallel mechanism to achieve an advantage in enlarging the workspace of the system, it needs a motion planning algorithm to choose the specific control inputs to determine the desired motion trajectory. This motion planning algorithm causes difficulty in achieving real-time control performance due to its structural complexity. However the redundant parallel mechanism presented in this paper is a redundant parallel mechanism with partially decoupled architecture in its rotational motion. Therefore modified Eclipse-II redundant parallel mechanism can realize effective real-time control performances and continuous 360-degree rotational motion in any direction of the moving platform with six degrees of freedom.

정부 3.0 정책에 따라 국가차원의 공공데이터 개방정책 추진으로 공공데이터는 양적으로 증가하였으나 수요자가 원하는 고품질 공공데이터 제공은 미흡한 현실이다. 이를 해결하기 위해 품질관리체계 확보를 위한 제도를 마련하고 공공 기관들의 품질관리체계 도입·정착을 유인할 필요성이 제기되고 있다. 본 논문은 2014년에 개발된 공공데이터 품질관리 성숙도 모델 및 공공부문의 유사 인증모델을 참조하여 공공데이터 품질평가 모델을 개발하였다. 본 모델에서는 공공데이터 품질관리 평가심사의 단위와 기준을 정의하며 공공데이터 품질관리 성숙도 모델의 품질지표를 기반으로 품질평가제 시행에 필요한 세부적인 평가심사의 세부 기준을 제공한다.

Purpose: Examining current status of nursing intershift handover practice would provide opportunity to identify areas in need of improvement. The aim of this study was to describe nursing intershift handover practice in Korean hospitals. Methods: A cross-sectional survey using questionnaire was used to collect data. A total of 788 nurses working in general hospitals had participated. Results: More than half of the nurses participated responded that they used kardex for verbal handover (51.8%). The average time took for handover was 40.2 minutes (SD=14.7). Only 5.8% of nurses were satisfied with intershift handover practice. 72.9% of respondents did not have manuals for handover and 86% of nurses considered intershift handover manuals were necessary. Most nurses considered intershift handover pratice as an important component for patient safety (99.2%). The causes of handover error were interruption during handover, high work load, and stress/fatigue of nurses. Conclusion: The findings of this study indicated a need to develop handover practice guidelines which outline pertinent details. Intershift handover practice guidelines could provide consistency and structure to the information that is handed over.

Purpose: This study was done to identify effective non-pharmacological intervention programs for the aged with hypertension by reviewing related research studies in Korea and other countries Method: Analysis was done of 29 related articles 12 domestic studies and 17 studies from other countries published between 1980 and 2007 Results: 1) All domestic studies were quasi-experimental designs whereas 16 foieign studies were RCTs Ten foreign studies and 2 domestic studies used multidisciplinary approaches Average number of participants was 26.9 in Korea and 181.5 in other countries Duration of intervention in other countries was longer than Korea 2) In other countries the most popular intervention methods were education and counselling focused on lifestyle modification and exercise whereas relaxation and complimentary methods were most common in Korea 3) The interventions that showed significant positive effects on blood pressure were education and counselling focused on lifestyle modification (7 studies) exercise (7 studies) and relaxation methods (1 studies) Conclusion: When developing intervention programs for the aged with hypertension it is essential to use multidisciplinary approaches focused on changes in health behavior to improve lifestyle As for the research design larger RCT research studies with longer intervention periods are necessary to identify causal relationship.
