This research describes the ConOps(Concept of Operations) of sea-based guided weapon systems. The ConOps describes how the proposed system is to be used and is more descriptive than technical in terms of various stakeholders. It should be prepared to support the concept of the life cycle stage of the system. Developing ConOps plays an important role in ensuring that operational/maintenance, maintenance, and acquisition and development areas are better understood by users' needs and expectations. In this point of view, this work presents the process of deriving ConOps and aims to derive operational concept of maritime guided weapon system by using tools.

As helicopter technology has been upgraded, today its oceanic operation is considered to be usual. In oceanic operation of helicopter, the effect of severe wind, wave, and corrosion must be investigated and the operation procedures for safety as well as the motion of shipboard arising from maneuvers of ship must also be considered. In this paper, it describes the result of trade-off study for shipboard landing and its operation procedure including dynamic interface between ship and aircraft in ship operation and gives a simulation results to implement the oceanic operation of tilt rotor aircraft.

Defence Information System has surely required the guarantee of interoperability between systems as performing task oriented functions. To improve interoperability between them and use the benefits of component based development, defense officers are planning to develop COE like a kind of component bank concept. Defense component development methodology(ADDMe) within COE is a new approach of component based methodology for Defense environment after comparing, analyzing, and synthesizing with traditional CBDs. In this paper we introduce advanced defense component development methodology(ADDMe) and present checklist for improving interoperability between Defence component based systems which are developed with ADDMe. With our proposed interoperability's checklist, we can improve interoperability of defense component based systems through applying per each phase of ADDMe.

The purpose of this paper is to see what the problem is and what the direction of the strategy of asset management after this study has analyzed asset management status of domestic life insurance companies according to interest rate trends, analyzing in time series management asset lists, asset distribution state, and securities list of life insurance companies during 2000~2014. It has carried correlation analysis and regression analysis between yield and bond interest KOSPI index. As the study result, life insurance companies have managed assets in stability than profitability. The correlation coefficient between interest rate and performance rates of total asset, management asset and securities is highly plus, correlation of management asset performance rate is higher than that of total asset performance rate, and the correlation of securities performance rate is higher than that of management asset performance rate. The correlation coefficient of KOSPI and performance rate shows minus. The suggestion is that the change of asset management is required as the interest decline rises up a reverse margin risk because of the asset management of stability.

The general ground control system has control and information display functions for the operation of a single unmanned aerial vehicle. Recently, the function of the single ground control system extends to the operation of multiple UAVs. As a result, operators have been exposed to more diverse tasks and are subject to task overload due to various factors during their mission. This study proposes an adaptive ground control system that reflects the operator's condition through the task overload measurement of multiple UAV operators. For this, the ground control software is developed to control multiple UAVs at the same time, and the simulator with six degree-of-freedom aircraft dynamics is constructed for realistic human-machine-interface experiments by the operators.

This paper is to measure the sensitivity of relations in communication network operation. In order to procure an important adequacy in the network operation and quality improvement, it is necessary to increase network operation efficiency and analyze the characteristic of network operation. Finally, we analyze costing appropriate operation, propose profit increase scheme and apply realistic business. First of all it's important to improve and estimate a proper operating cost thoroughly and comprehensively. Because the important issue of this process is quality process and this quality process occurs customers' satisfaction, therefore, to make a mutual relation in-between individual change of each element is to analyze a reasonable standard. So, for this reason we study on structuring nice moods for network operation and estimating many scenarios for measuring efficiency. Especially those in economic and sensitivity based. It will be the development of analyzing methods which suites the service and communication system. The result of this study gives a basis for making a flexible and highly predictable system by pre configured sensitivity analysis of each scenarios.

최근 기업 환경이 복잡해지고 분산화 되어감에 따라 각 기업간의 그리고 부서 및 지점간의 프로세스 상호운용 및 협력이 중요한 이슈로 떠오르고 있다. 이러한 시점에서 기업간 비즈니스 프로세스와 메시지 등을 교류할 수 있는 상호운용성이 기업들에게 필수적인 요소로 고려되고 있다. 지금까지 많은 기술자와 연구자들에 의해 기업간 워크플로우 상호운용성을 해결할 수 있는 기술적인 노력이 꾸준히 이루어져 왔다. 기술적 문제의 해결도 중요하지만 이보다 우선적으로 해결되어야 될 것은 비즈니스 프로세스 상호운용성에 대한 개념적 모델링과 정확한 분석이다. 본 논문에서는 기존의 워크플로우 패턴들에 대한 연구들을 정리해 보여 줄 뿐만 아니라, 여러 기업간 비즈니스 프로세스가 상호운용될 시 충돌을 유발시킬 수 있는 패턴들을 제시할 것이다. 이러한 패턴들에 관한 연구는 여러 기업들이 복잡한 비즈니스 프로세스를 문제없이 효율적으로 상호운용할 수 있도록 도움을 주는 기본적인 정보가 될 것이다.

통신기술의 발전과 함께 고도화, 지능화 되어가는 통신망 운용환경에 능동적으로 대처하고, 이질적(heterogeneous)이고 복잡하게 구성된 통신망 구성요소(교환, 전송 및 가입자/선로장치)들을 효율적으로 관리하기 위해서는 표준화된 개방형 방식의 총체적이고 일원화된 통신망 운용관리기법이 요구된다. 국제표준화기구인 ITU-T에서는 이를 위해 TMN(Telecommunications Management Network) 개념을 국제표준으로 권고하고 있으며, 세계 각국의 통신운용체(PNOs : Public Network Operators)에서는 이 개념을 통신망 운용관리의 하부 기반구조로 도입하고 있는 상황이다. 본 논문에서는 TMN개념을 기반으로하여 통신망운용관리시스팀을 개발운영하고, 이를 하부 기반구조로 하는 종합망운용관리체제를 구축함에 따른 경제적인 효과를 정성적인명과 정략적인 측면으로 구분하여 제시하였다.

지휘통제, 전략전술, 물자관리 등 다양한 분야에서 사용되는 국방정보시스템들은 필요에 따라 원활하게 상호운용 되어야 군 정보화 효과를 극대화할 수 있다. 이 논문은 정보시스템 상호운용 수준(LISI)에 의거해서 국방정보시스템 간의 상호운용 능력을 전자설문 방식으로 측정하고 테스팅을 통해서 확인하는 기법을 제시한다. 제시된 전자설문 기법은 구현옵션 집합과 질의문을 이용해서 정보시스템 간의 잠재적 상호운용 수준을 측정한다. 반면에 테스팅 기법은 전자설문을 통해서 결정된 두 정보시스템 간의 잠재적인 상호운용 수준을 분산 소프트웨어 테스팅 기법을 사용하여 실질적으로 측정한다. 마지막으로 제시된 전자설문 기법과 테스팅 기법을 바탕으로 개발된 상호운용성 평가도구를 소개하고 적용결과를 제시한다.
