This paper proposed risk management approach as a self-audit framework to achieve the goals which might be common among the records management organizations in Korea governmental and public area. After introducing the history and the concept and process of risk management approach and examining DRAMBORA's framework, the processes and the methods of risk management for the electronic records which are customized from DRAMBORA are explained in details: How to define the business context of organizations, how to determine the business functions and activities and related risks, how to assess the level or severity of each risks and some considerations related to risk assessment. As a result, this paper shows that application of DRAMBORA's framework to the electronic records management organizatioins is not only possible but also useful and effective. The critical point for the success of application for DRAMBORA's framwork or the risk management approach itself each organizations which wants to accept that framework should define its own business functions and activities and the goals in respect areas.

This paper considers the integrated process control procedure for detecting special causes in an IMA(1,1) noise process that is being adjusted using a minimum mean squared error adjustment. As a SPC procedure, we use a GLR chart for detecting special causes whose effects are the sustained shift or the sustained drift in the process mean, and the sustained shift in the process variance. For the design of the GLR chart, we derive expressions for the control limit which accurately satisfies the given in-control ARL.

Construction Management tends to create a formal procurement resulted from recent legislative procedures system in domestic construction industry. However, the fact that construction Manager(CMr) has been chosen, in practice, under a poor circumstance in selecting and discriminating specialty requires the more optimal procedures. Therefore, in this research, we analyze the existing shortcomings. the various procedures, influence factors, and the criteria to be considered in selecting and evaluating CMr. Also. this study suggests the improved method based on the facts above. To accomplish the construction project successfully, it is one of the advanced schemes to choose an adequate CMr needed to the project through the precision in the formation and application of the procedure as well as the suggested criterion in selecting CM.

The run length is defined as the number of samples or subgroups taken before the control chart statistic exceeds the control limits. Because the distribution of run length is typically asymmetric and has a large variability, it may not be appropriate to use ARL (average run length) alone to design control charts and evaluate performance. In this paper, we introduce the concept of percentile (PL)-based design of control charts, and propose the procedure for PL-based design of EWMA (exponentially weighted moving average) charts. For the PL-based design of EWMA, we present a fitted function for the control chart coefficient, given specific percentile parameters. Additionally, we perform simulations to compare the proposed design with the ARL-based design. The simulation results show that the proposed design yields improvements in monitoring in-control processes while maintaining the ability to detect out-of-control performance.

원전 구조물의 대부분은 해안가에 위치하고 있어 염해와 장기적으로 발생하기 쉬운 피로, 중성화등 각종 열화조건에 노출되어 있다. 한편 구조물의 유지관리에 관한 기술은 근본적으로 체계적으로 확립된 절차에 따라 수행되어야 하는 것이 원칙이며 특히 원자력 발전소의 경우에는 결함요인을 사전에 제거함으로써 원자력 안전성에 대한 신뢰도를 높이기 위한 자체기술의 확립이 필요하다. 이러한 필요성에 따라 "원전 안전성 관련 콘크리트 구조물의 열화에 관한 연구"에서는 체계적인 열화현상 검사 절차 및 유지관리기술의 핵심 요소라 할 수 있는 각종 검사 및 이력사항들에 대한 데이터베이스 시스템의 구축, 표준적인 보수.보강 절차를 제시하였으며, 이러한 제반 성과들이 원전 구조물의 유지관리업무에 실용화 될 때 원전의 안전성 향상에 크게 기여하리라 생각된다.여하리라 생각된다.

본 연구에서는 위성영상 활용 지능형 재난관측·감시 기술 개발을 목적으로 위성영상과 멀티소스(CCTV, 항공영상, 공공DB 등)와의 연계·융합을 통해 재난상황관리의 정확도 향상과 위성영상 활용성 제고 방안을 제시하고자 하였다. 위성영상 수집·배포시스템으로부터 전달되는 위성영상과 멀티소스의 연계 융합을 통한 재난상황정보의 표출을 목적으로 상황판연계 표출시스템 가동 절차와 위성영상 수집을 통한 위험탐지 알고리즘과의 연계를 위해 재난상황업무 기반 시스템 가동절차를 수립하고, 위기관리표준 매뉴얼 상 상황업무절차를 적용해 예비설계를 진행하였다. 상황실 실무자 설문을 통해 작성된 시스템 요구사항과 규격서를 기반으로 상황업무절차를 적용해 먼저업무시스템 설계를 진행하였다. 평시에는 GIS통합상황판에서 관리됨을 전제로 위성영상 수집에 대한국가적 예산 투입 측면을 고려해 중대본 설치가 필요한 대형재난 발생상황을 가정하여 상황판연계·표출시스템의 가동되도록 설계하였다. 또한, 위성영상 분석을 통한 피해위험도와 재난이력통계 등 멀티소스와 중첩한 결과를 실시간으로 표출함에 따라 상황실근무자는 재난확산 여부를 판단하고, NDMS를 통해 재난상황을 전파할 수 있도록 설계하였다. 상황판연계 표출시스템의 원활한 데이터 입/출력을 위해 재난유형 및 분석단계별 클래스 정의, 유스케이스 ID(요구기능)와 1:1 또는 1:n매칭을 수행하여 재난유형 및 분석단계별 클래스를 정의하였다. 정의된 클래스는 유스케이스인 요구기능과 매칭을 수행하였고, 시스템 가동절차 중 피해위험도분석, 재난이력통계, 중첩결과표출, NDMS 상황전파에 대한 상황업무절차를 기반으로 산불·홍수·산사태·대설·태풍 총 5종의재난별 시퀀스를 설계하였다. 마지막으로 화면정의서와 UI/UX설계서를 기반으로 Figma를 통해 시스템구동화면을 사전에 모의하였다. 향후, 진행되는 연구에서는 위성영상과 멀티소스를 연계한 화면을 실체화하여 더욱 정확한 재난상황관리가 가능하도록 NDMS 연계 상황판 표출 시스템을 개발하고자 한다.

Many studies have been conducted to quickly detect out-of-control situations in autocorrelated processes. The most traditionally used method is a residual control chart, which uses residuals calculated from a fitted time series model. However, many procedures for monitoring autocorrelated processes using statistical learning methods have recently been proposed. In this paper, we propose a monitoring procedure using the latent vector of LSTM Autoencoder, a deep learning-based unsupervised learning method. We compare the performance of this procedure with the LSTM Autoencoder procedure based on the reconstruction error, the RNN classification procedure, and the residual charting procedure through simulation studies. Simulation results show that the performance of the proposed procedure and the RNN classification procedure are similar, but the proposed procedure has the advantage of being useful in processes where sufficient out-of-control data cannot be obtained, because it does not require out-of-control data for training.

In this study, safety management procedures were developed based on domestic and foreign guidelines and related maritime law to ensure the safe development and implementation of smart autonomous ship technology and Samsung Heavy Industry. The safety management procedure was developed according to the guidelines for (MASS) sea trials (MSC.1/Circ.1604, Annex: Interim guidelines for MASS trials), proposed by International Maritime Organization (IMO) for the relevant authorities and stakeholders of MASS to properly conduct tests of systems and infrastructure related to safety and environmental protection. The developed safety management procedure applies to the maritime demonstration test of a system applying autonomous navigation element technology mounted as a navigation aid on a ship operating under a watch system, while complying with the environmental protection and navigation safety of the coast of Korea.

This study proposes a model of collection process for real-time forensic data, in which the manager was to respond to infringement incidents in terms of system operation and inspection and to collect, analyze and restore forensic data immediately after an incident took place. The suggested model was modeled in seven processes according to functional elements. Unlike the old and managerial forensic processes, the model allowed the manager to react to infringement incidents in the aspects of system operation and inspection and to follow the processes of collecting, analyzing, and restoring forensic data in case of an incident. There also was a feedback process designed towards the step of gathering forensic data through the stages of systematizing reaction strategies in order that he or she be able to bring about comprehensive and structural responses to an incident like the former processes in which it is difficult to bring about instant responses.
