Systems engineering requirement verification model developmetn for High Speed Railway systems in progress is a national large system development program that is not only large-size and complex but also multi-disciplinary in nature. For the High Speed Railway TEP development, verification requirements that could verify system function, performance, and constraint, should be derived from SSS(system Segment specification). Hereafter, this could be referred to as verification requirements. System engineering process establishes traceability between verification requirements and system requirements. These tasks could be accomplished by the schema. using computer-aided Systems Engineering tool(CORE), High Speed Railway program can become a database and other system related to High Speed Railway program will be developed effectively and efficiently.

최근 국제무역질서에 있어 국제화, 세계화는 가속화되어가고 있으나 국내 산업계의 생산성과 효율성 등은 이에 미치지 못하고 있는 실정이다. 따라서 경영층의 강력한 리더십 및 종업원의 자발적인 참여를 바탕으로 종업원과 고객의 만족을 동시에 추구하여 궁극적으로는 조직의 장기적 발전에 초점을 맞추고 있는 TQM개념〔Richard, 1993〕의 도입이 급박한 상황이며, 실제로 많은 기업이 이의 도입을 추진 또는 완료하였다. 이미 도입이 완료된 기업에 대해서는 지속적인 평가 및 개선이 요구된다 하겠다. 본 논문에서는 대덕연구단지내의 K 엔지니어링사를 대상으로 조직구성원들의 품질시스템에 대한 인식 및 자체적인 평가에 근거하여, K 엔지니어링사 품질경영시스템상의 문제점도출 및 이의 개선책을 제시하고 하였다. 본 논문에 적용된 평가 모델은 TQM을 적용하는 유사기업들에서도 활용할 수 있으리라 사료된다.

최근 건설분야에 화두가 되고 있는 건축정보모델링(BIM, Building Information Modeling)은 건설산업의 패러다임 전환을 통한 새로운 성장동력의 미래로 부각되고 있으며, 건축분야는 서울시, 용인시, LH공사 등 BIM을 활용한 공공 발주사례가 확산되는 추세다. 토목분야는 건축보다 기간이 길고 비용이 크며 이해당사자가 너무 다양해서 발생하는 정보의 양이 방대할 뿐만 아니라 활용분야를 다양화하지 못하고 이를 뒷받침해주는 제도나 지침의 부재 등으로 인해 건축분야보다 BIM도입이 늦어지고 있다. 이에 토목분야에서 활용할 수 있는 3차원 형상정보와 관련된 정보모델표준, 지침, 가이드를 개발하기 위해 BIM 적용시 가장 효과가 크고 도입의지가 강한 엔지니어링사의 BIM에 대한 인지도 분석을 통해 토목분야 BIM 도입을 위한 기초자료로 활용하고자 한다.

금회 연구대상지인 진도 해역은 WQI지수 II, III등급 해역으로, 비교적 양호한 수질상태를 유지하고 있다. 최근 대명리조트는 이곳에 대규모 휴양시설을 계획 중에 있으며, 이에 따른 오수의 해양방류는 불가피할 것으로 보인다. 따라서, 오수의 해양방류로 인하여 대상해역의 오염이 우려됨에 따라 최적의 배수시설을 건설하여 수질악화를 방지하고자 한다. 배수시설에 따른 수질영향 예측을 수행하기 위하여 Delft3D-WAQ 모듈을 이용하여 당 해역의 수질특성을 재현 및 예측하였다. 또한, 상기 모델에 의한 모의결과의 정확도를 확인하고 보완하기 위하여 수직 와확산계수의 민감도 분석을 수행하였으며, 이를 통해 신뢰도를 확보하였다. 배수시설의 방류구 이격 거리 및 수층별 방류에 따른 수질변화를 검토한 결과, 해안에서의 이격거리가 멀고 중층에 방류할 경우 가장 효과적인 희석률을 보이는 것으로 나타났다.

The aim of this study is to propose the design suitable for sustainability evaluation model of the mobile industry considering system process (SEP). Although a quantitative evaluation was conducted on the link between the national sustainability report and the mobile industry, it was confirmed that it was difficult to identify stakeholders. So it is necessary to develop the design process suitable for the more operator-specific interfaces. The Human System Integration (HSI) methodology was proposed through linkage with work domain analysis. Agile methodology and Resilience engineering methodology were added for sustainable model design. The proposed sustainability system evaluation model is applied so that it can be easily used in all industries.

As the average life expectancy is rising, the population is aging and the number of chronic diseases is increasing. This has increased the importance of healthy life and health management, and interest in mobile health services is on the rise thanks to the development of ICT(Information and communication technologies) and the smartphone use expansion. In order to meet these interests, many mobile services related to daily health are being launched in the market. Therefore, in this study, the characteristics of users who actually use mobile health services were analyzed and a predictive model applied with machine learning modeling was developed. As a result of the study, we developed a prediction model to which the decision tree and ensemble methods were applied. And it was found that the mobile health service users' continued use can be induced by providing features that require frequent visit, suggesting achievable activity missions, and guiding the sensor connection for user's activity measurement.

In this paper, to increase the maintenance efficiency of the urban railway train control system and to build a standard data system, we collect as much as possible structured, unstructured, and semi-structured data, and collect data by sensing and monitoring the system status and system status and monitoring. pre-process function data(Identification, purification, integration, transformation) through effective data classification and maintenance activities business classification system was studied. The purpose of this is to define the data matrix model by considering the relationship with the data generated and managed in the O&M stage of the train control system operated by the urban railway together with the WBS model, and to reflect and utilize it in practice.

Multidimensional efforts such as budgeting, organizing, and institutionalizing are being carried out for the adoption of defense AI. However, there is little interest in eliminating duplication of defense resources that may occur during the AI adoption. In this study, we propose a theoretical conceptual model to optimize duplication of AI technology that may occur during the AI adoption in the vast defense field. For a systematic approach, the JCA of the US DoD and system abstraction method are applied, and the IMO logical structure is used to decompose AI requirements and identify duplication. As a result of analyzing the effectiveness of our conceptual model through six example defense AI requirements, it was found that the amount of requirements of data and AI technologies could be reduced by up to 41.7% and 70%, respectively, and estimated costs could be reduced by up to 35.5%.

Over the past decades, there have been numerous studies for approaches to build and operate electronic government systems. Among those studies, work breakdown structure(WBS) has been gained attention increasingly. As a general system engineering techniques. WBS is a kind of methods to engineer and manage electronic government systems effectively. WBS is to organizes tasks and data items for management and engineering for electronic government systems. In this paper, the authors proposed a conceptual WBS model for management and engineering electronic government systems. Also, the authors conducted a case study based on the conceptual WBS model. The results of this study provide useful insights and guidelines for applying the WBS to management and engineering for electronic government systems. The authors believed that the conceptual WBS models will be widely used to management and engineering an electronic government systems.
