Navy ship acquisition management business contributed to the korean Navy and defense exports with government suppliers in Korea for over 40 years. But due to advanced technology, development trend of Navy ship and defense export requirements, it enable to make a contribution to a better system improvement are being demanded. In this paper, an adjective Navy ship acquisition process is presented in order to improve the acquisition process takes the first step for acquisition planning process to enhance the efficiency and rationality that is based on consensus of Navy ship expert and experienced. In addition, systems engineering (SE) and quality control (QC) techniques based on Modeling and Simulation are investigated to carry out efficient project management and scientific quality control system in Navy ship acquisition process. Finally, it is suggested to apply SE/QC based on M&S for Navy ship acquisition process using civilian infrastructure and organizations in order to take advantage of the world's leading domestic industry based on considering the difficult conditions of Navy ship suppliers.

We conducted validation for asbestos quality control (QC) samples made by the developed method which was presented in our published paper. The main results of the validation study are as follows. The pooled coefficient variations of analytical results in three different concentrations (low, medium, and high concentration) for amosite and chrysotile were less than 20 %, which met the sample homogenicity criteria of NIOSH. Also we confirmed the homogenicity of asbestos samples by using the relocatable field slide. To evaluate the field applicability of the developed asbestos QC samples, the field validation was performed with four proficient asbestos analysts by using the statistical methods of AIHA asbestos PAT program. All analytical results from four asbestos analysts were located in the acceptable range.

This study introduces a methodology to evaluate different types of non-nuclear technologies to see how they are competitive to the nuclear technology for quality control (QC) and quality assurance (QA) in soil condition measurement for highway pavement construction. The non-nuclear methods including the Electrical Density Gauge (EDG) and the Light Weight Deflectometer (LWD) were tested for their performance against a nuclear gauge, and traditional methods were used as baselines. An innovative way of comparing a deflection gauge to a density gauge was introduced. Results showed that the nuclear gauge generally outperformed the non-nuclear gauge in accuracies of soil density and moisture content measurements. Finally, a framework was developed as a guideline for evaluating various types of non-nuclear soil gauges. From other perspectives rather than accuracy, it was concluded that the non-nuclear gauges would be better alternative to the nuclear gauge when the followings are considered: (1) greater life-cycle cost savings; (2) elimination of intense federal regulations and safety/security concerns; and (3) elimination of licensing and intense training.

본 연구에서는 기상청에서 수행하는 기존의 기상 관측에 대한 품질관리 절차 이외에 향후 스마트시티 등에서 활용될 수 있는 머신러닝 기반의 Internet of Things (IoT) 도시기상 관측 자료에 대한 품질검사 기준을 제안한다. 현재 기상청에서 종관기상관측(Automated Synoptic Observing System, ASOS)과 방재기상관측(Automatic Weather System, AWS) 기반으로 설정한 기준이 도시기상에 적합한지 확인하기 위하여 서울시에 설치된 SKT AWS 자료를 기반으로 사용성을 검증하였고, IoT 자체의 데이터가 가지는 특성을 고려하여 최종적으로 머신러닝 기반의 품질검사 알고리즘을 제안하였다. 품질검사 방법으로는 IoT 기기 자체에 대한 결측값 검사, 값 패턴 검사, 충분 데이터 검사, 통계적 범위 이상 검사, 시간값 이상 검사, 공간값 이상 검사를 먼저 수행하고, 기상청에서 제시하고 있는 기상 관측에 대한 품질검사인 물리한계검사, 단계검사, 지속성 검사, 기후범위 검사, 내적 일치성 검사를 5가지 기상요소에 대하여 각각 수행하였다. 제안한 알고리즘의 검증을 위하여 인천광역시 송도에 위치한 관측소에 실제 IoT 도시기상관측 데이터에 이를 적용하였다. 이를 통해 기존의 기상청 QC로는 확인할 수 없었던 IoT 기기가 가질 수 있는 결함을 확인할 수 있고, 알고리즘에 대한 검증을 진행하여 향후 스마트시티에 설치될 IoT 기상관측기기에 대한 품질검사 방법을 제안한다.

This research introduces the Financial Effect Measurement (FEM) models which measures both the improvement and the innovation performance of Quality Control Circle (QCC) and activities of Six Sigma. Concepts and principle of Comprehensive Income Statement (CIS), Balanced Scorecard (BSC), Time-Driven Activity Based-Costing (TDABC) and Total Productive Maintenance (TPM) are applied in order to develop the 4 FEM models presented in this paper. First of all, FEM using CIS depicts the improvement effects of production capacity and yield using relationships between demand and supply, and line balancing efficiency between bottleneck process and non-bottleneck processes. Secondly, cause-and-effect relation of Key Performance Indicator (KPI) is used to present Critical Success Factor (CSF) effects for QC Story 15 steps of QCC and DMAIC (Define, Measure, Analyze, Improve, and Control) of Six Sigma. The next is FEM model for service management innovation activities that uses TDABC to calculate the time-driven effect for improving the indirect activities according to the cost object. Lastly, FEM model for TPM activities presents the interpretation of improvement effect model of TPM Capital Expenditure (CAPEX) and Operating Expenditure (OPEX) maintenance using profit, cash and Economic Added Value (EVA) as metrics of enterprise values. To better understand and further investigate FEMs, recent cases on National Quality Circle Contest are used to evaluate new financial effect measurement developed in this paper.

건설 품질관리는 건설 프로젝트의 성공적 수행을 위한 필수요소이다. 최근 ICT 기술 적용이 활성화 됨에 따라 현장 검측 업무에 첨단 기술 및 장비를 활용하기 위한 다양한 시도가 이루어지고 있다. 그러나 개별적 검측업무에 대한 첨단기술 적용에 앞서 전체 검측업무를 선제적으로 계획하는 것이 매우 중요하다. 본 연구의 목적은 건설 검측업무에 첨단 기술 및 장비를 활용하기에 앞서 검측대상과 관련 정보를 명확히 도출하기 위한 데이터베이스와 그 데이터 베이스를 활용하기 위한 알고리즘을 개발하는 것이다. 또한 건축 시공계획에 따라 검측업무에 해당하는 액티비티를 자동 생성하기 위한 프레임워크를 제안하였다. 그 방법으로 국토교통부에서 고시한 책임 상주 감리 체크리스트의 검사 항목을 바탕으로 검측 대상, 검측 시기, 검측 방법, 검측 범위, 검측 제약요소를 분석하고 분류하였다. 본 프레임워크는 철근 콘크리트 공사 사례에 적용되었다. 개발된 건설 검측 업무 액티비티 자동 생성 프레임워크는 건축 시공을 위해 사용하는 공정관리 프로그램, 검측업무 및 검측기술을 연계하는데 적용할 수 있다. 향후 다양한 건설 프로젝트의 검측 업무 시, 액티비티 자동 생성 및 자동화를 위한 기초로 활용될 것으로 판단된다.

The paper aims to apply a model of continuous quality improvement (CQI) to Taiwan provincial Pin Ton hospital. Tools of quality control were used both total quality management (TQM) and quality control circle (QCC) in order to approach the objective of ${\ulcorner}$higher quality, higher efficiency, lower cost${\lrcorner}$. During two years, this hospital has organized thirteen QC circles that were classified three categories according to that objective: four circles work for higher quality; the other four circles work for higher efficiency; five circles for lower cost. After implementation, several results were found from two viewpoints. From viewpoint of tangibility, one of the most outcomes is to reduce labor cost from 56 persons to 28 persons of temporary employees. From viewpoint of intangibility, the result was evaluated using radar chart to compare the difference after improvement. This paper is going to report the process of CQI for the hospital management because it is a new issue in Taiwan since 1997

An important problem to be carried into a plan on the occasion for introduction of TQC is to establish the clear-cut policy and workable system on QC. In connection with escalation the product liability in recent days, especially, a point to he considered in relation the real state of enterprise, it seems likely to be difficult an effective performance without distribution of the definite duality function to each departments in the company, and to define the quality function, it should be educed and coordinated under agreement organization wide participation and conciliation. In this paper, we have tried to have a more effective graft the European style QC on the oriental enterprise, by means of presenting a model that manages synthetically a way of deployment the fundamental factors affecting quality, and establishing the control subject in each function unit.

영상의 표시는 PACS 및 디지털 의료 영상계에서 중요한 요소이다. 동일한 디지털 데이터에 대한 영상의 질은 디스플레이 장치의 물리적 특성, 최적화된 설정 및 교정, 주위 불빛 조건 등에 의하여 영향을 받는다. 디스플레이 장치는 사용시간에 따라서 휘도 감소 및 설정값들의 변화에 의하여 성능이 저하된다. 디스플레이 시스템의 성능이 지속적으로 저하되기 때문에 일정한 주기마다. 정도관리를 수행하여야한다. 정도관리 효과를 평가하기 위하여 진단에 사용되는 10대의 평판 LCD 디스플레이 장치를 선택하였으며, 설정값 교정 전과 후에 휘도 반응, 휘도 공간 의존도, 분해능, 그리고 색도 변화를 정량적으로 측정하여 평가하였다. 정도관리 효과는 휘도 반응과 휘도 공간 의존도 테스트에서 다소 큰 변화가 있었으나 분해능 및 디스플레이 색도에서의 영향은 크지 않았다. 디스플레이 장치의 주기적인 정도관리는 의료영상을 일관성 있게 표시하기 위하여 필수적이다. 본 연구 결과는 의료용 디스플레이 장치의 정도관리에 대한 항목 선정 및 주기를 결정하는 데 중요한 역할을 할 수 있을 것이다.
