항공기의 엔터테인먼트 시스템은 고정된 모니터를 사용하는 대신에 승객 개인의 휴대용 전자기기를 사용하는 형태로 그 패러다임이 바뀌었다. 이로 인해 기내 설비는 간소해진 반면 휴대용 전자기기들의 전기 충전으로 안전에 대한 리스크는 증가되었다. 송신 기능이 없는 개인 휴대전자기기와 달리 와이파이 기능이 있는 전자기기(T-PED)의 사용이 허용되고 기내에서 배터리의 충전도 요구된다. 본 연구에서는 기내 무선 환경과 엔터테인먼트 서비스의 변화에 따른 영향을 조사하기 위해 NASA 항공안전보고시스템을 이용하여 기내 전자기기 사용 관련 자료를 분석하였다. 이를 기초로 하여, 항공기 안전관리 관점에서 비행 중에 발생된 객실 전자장비나 승객 휴대용 전자기기(특히 스마트폰)로 인한 이벤트 발생 사례를 공유하여 개인용 전자기기의 위험성을 분석하였다. 이러한 분석을 위해 잠재적 위해요인의 식별과 리스크 평가 작업이 수행되었으며, 최종적으로 휴대용 전자기기의 안전한 사용을 위한 리스크 완화 전략이 제시되었다.

2014년 철도운영자들과 철도시설관리자의 자발적인 안전관리를 정착시키기 위하여 철도안전법에서 '철도안전관리체계'를 강화하였다. 이에 따라 위험도를 평가하고 위험도를 관리하기 위한 안전대책을 수립하고 시행할 것으로 판단하였으나 현재 위험도 평가 체계는 개별 분야 내 단편적인 안전관리 수준으로 진행되고 있다. 또한 안전관리체계의 기술기준에서 철도 운영기관의 위험도 평가에 관한 내용이 의무사항으로 명시되어 있어 철도시설 및 철도차량유지보수의 위험도 평가를 위한 표준화된 기준이 필요하다. 따라서 본 논문에서는 최근 10년간 철도사고 데이터를 분석하여 먼저 철도 위험도 수준을 검증하였고, 철도차량유지보수 부분에서 데이터를 기반으로 개발된 상태기반 스마트 유지보수 시스템 사례를 통해 위험도를 효과적으로 평가하고 관리할 수 있는 표준화된 프레임워크를 제시하였다.

Objective: This study explored the reuse of data captured into an electronic nursing record system using the International Classification for Nursing Practice to support nursing research of inpatient's falls. Methods: Risk factors relevant to inpatients falls ;n an acute setting were identified from the literature review. Four risk assessment tools and two risk identification studies were selected. To examine the availability of coded data in an electronic nursing record system for the identified fall fisk factors, we reviewed 11.319 hospital-day records of 118 patients who were reported by the self-report system. Results: We identified 24 fall risk factors of five categories from the literature review, which were used to identify the standard nursing statements addressing fall risks. One hundred thirty five nursing statements were searched from the hospital's nursing data dictionary of statements and were matched with 14 fall fisk factors. Using the 135 statements. we found that mental status, catheter of drip in situ, abnormal gait, insomnia, surgical procedure. and dizziness/vertigo appeared frequently in the nursing records of inpatients with fall s. Also we found 6 risk factors more through the record review. Conclusion: The electronic records would be a good research source for inpatients' falls. Specifically international classification for nursing practice based nursing record system has the potential for promoting clinical researches.

본 논문에서는 자동차 기능안전 표준인 ISO 26262에서 요구하는 위험원 분석 및 위험 평가에서 온톨로지와 추론 규칙을 적용하는 방법을 제안한다. 위험원 분석 및 위험 평가는 일반적으로 수작업으로 수행되어 많은 노력이 소요되고 오류가 발생하기 쉬우며 일관성과 정확성이 부족한 문제점이 있다. 이러한 문제를 해결하기 위해서 본 논문에서는 위험원을 온톨로지로 표현하고, 평가를 위한 온톨로지 규칙을 정의하여 자동화하고 일관성 및 정확성 문제를 개선한다. 본 제안 방법을 검증하기 위해서 ESCL(electronic steering column lock) 시스템에 적용하였다. 온톨로지 규칙 적용 결과를 DL(Description Logics) Query를 실행하여 제대로 동작하는지 확인하였으며, 이를 통해 위험 평가 시에 발생할 수 있는 오류를 파악할 수 있었다.

Based on the risk factor evaluation for the file format, this paper defines the procedures for presenting the long-term preservation plan for that format and the technical information registry necessary for building the system. This is a procedure to perform a risk assessment for the format, evaluate the risk, and select a long-term preservation strategy based on the information registered in the registry and information on the external signature and internal signature of the electronic record. We also reviewed the criteria for selecting appropriate long-term preservation strategies in the process and provided the criteria for adopting each detailed strategy of migration and emulation, which are long-term preservation strategies. And we implemented this process as a long-term preservation decision support system. This system can be used to provide guidelines for the maintenance, management, service and long-term preservation of information resources of electronic records in public institutions such as National Archives of Korea and Libraries.

Purpose: This study was conducted to obtain data for the development of an effective fall risk assessment tool for pediatric inpatients through a systematic review and meta-analysis of the diagnostic test accuracy of existing scales. Methods: A literature search using Medline, Science Direct, CINAHL, EMBASE, and the Cochrane Library was performed between March 1 and 31, 2018. Of 890 identified papers, 10 were selected for review. Nine were used in the meta-analysis. Stata version 14.0 was used to create forest plots of sensitivity and specificity. A summary receiver operating characteristic curve was used to compare all diagnostic test accuracies. Results: Four studies used the Humpty Dumpty Falls Scale. The most common items included the patient's diagnoses, use of sedative medications, and mobility. The pooled sensitivity and specificity of the nine studies were .79 and .36, respectively. Conclusion: Considering the low specificity of the pediatric fall risk assessment scales currently available, there is a need to subdivide scoring categories and to minimize items that are evaluated using nurses' subjective judgment alone. Fall risk assessment scales should be incorporated into the electronic medical record system and an automated scoring system should be developed.

This paper presents a basic ECU(Electronic Control Unit) hardware development procedure for the functional safety of in-vehicle network systems. We consider complete hardware redundancy as a safety mechanism for in-vehicle communication network under the assumption of the wired network failure such as disconnection of a CAN bus. An ESC (Electronic Stability Control) system is selected as an item and the required ASIL(Automotive Safety Integrity Level) for this item is assigned by performing the HARA(Hazard Analysis and Risk Assessment). The basic hardware architecture of the ESC system is designed with a microcontroller, passive components, and communication transceivers. The required ASIL for ESC system is shown to be satisfied with the designed safety mechanism by calculation of hardware architecture metrics such as the SPFM(Single Point Fault Metric) and the LFM(Latent Fault Metric).
