최근 무인이동체를 활용한 서비스 수요가 다양해지고 무인이동체 서비스 시장의 규모가 급격하게 증가하고 있다. 특히 산불 진압, 우편 배송, 시설 관리 등 공공임무 분야에서의 무인이동체 활용 서비스 요구도가 높아지고 있다. 이러한 요구도의 증가와 함께 무인이동체 기반의 다양한 임무 수행을 지원하기 위한 무인이동체 탑재용 임무소프트웨어 개발의 중요도가 갈수록 높아지고 있는 추세이다. 공통화 된 임무소프트웨어 개발을 위해서는 다양한 공공기관에서 공통적으로 필요한 임무 분석을 통해 재사용 가능한 기능들을 라이브러리로 개발하고, 이를 활용하여 무인이동체 관련 기업들이 쉽게 임무소프트웨어를 개발할 수 있도록 구조 설계가 이루어져야 한다. 본 논문에서는 공공임무용 무인이동체 전용 임무소프트웨어 연구 동향에 대해서 언급하고, 소프트웨어 개발을 위한 정형화된 임무소프트웨어의 구조 설계를 제안한다. 마지막으로, 임무소프트웨어와 데이터 플랫폼 간 데이터 전송 아키텍처를 제안한다.

The objective of this study is to clarify the early state of modern architecture, specifically mission architecture, with the introduction of the Christianity, and for the goal it deals with the architectural activities of pioneer missionaries. Especially it is a piece in a series of those researches after on Graham Lee, and it is focused on the other representative missionary, R. M. Wilson, A. M. Sharrocks, and C. A. Clark. Although coming in the capacity of a medical doctor or an educator, they should play all kinds of roles, such as carpenters, educators, and officers. For this mission, even they didn't have a professional knowledge for construction, they should carried on to establish mission compounds, only with their experience and informations. In this process they needed to be assisted by Korean carpenters, surely. The architectures born by them-selves are designed with a unique eclectic style compounded with those of Korean traditional and occidental. That is to say, the pioneer missionaries made a profound influence to create a new tradition of modern architecture in Korea, which is called as Korean-occidental eclectic style in the period of transition. Moreover, some pioneer missionary, such as Sharrocks, took a part in education of architectural skills. The educated carpenters seemed to be called from outside, and the unique styles could get spread away. On this point this paper has the meaning to clarify historically the continuous development of the Korean architecture through the survey on their activities, on the contrary of the existed recognition that Korean modern architecture has been evaluated to be imported from outside; therefore having a crevice with the its own architectural tradition.

전장공간은 다양한 무기체계가 유기적으로 활용되고 있으며, 자원의 성능 및 통신환경이 제약되고 환경의 가변성이 높은 특징이 있다. 이러한 전장환경에서 운용되는 자원의 접근성과 통합성의 한계를 극복하고 유연한 조합을 통해 임무를 수행할 수 있는 방안으로 서비스 지향 구조 기반의 기술을 접목시키는 연구들이 진행되고 있다. 본 연구에서는 지휘관이 전장 환경에서 임무에 필요한 다양한 SW를 서비스 기반으로 운용하기 위해 서비스 기반의 임무 계획 및 수행을 지원하는 계층형 임무서비스 모델을 제안한다. 또한 워크플로우 기술과 시맨틱 능력기반 추천을 활용한 개발도구를 구현하고 전투 임무 시나리오에 적용하여 실효성을 보이고자 한다.

Since Korea disclaimed to open the ports, Korean architecture has met the impetuous transformation. Although there would be various factors of this transformation, the new-coming architecture by missionary seemed to be a significant one, and many researches have been carried out on this theme in diverse viewpoints. However, because these researches have preponderated on the Catholic tradition, it is deficient for clarify the whole history of mission architecture. Therefore, this research has the meaning to enrich the history of Korean modern architecture by making balance. First of all, this paper is focused on the activities of one missionary, Graham Lee. He is a practical missionary at the beginning, his architecture made a critical influence in Korean traditional architecture. Graham Lee was born in Rock Island, Illinois, 1861, and he determined to become a missionary through grown up. He spent his boyhood by working as a plumber for his purpose and studied in a university afterward. Graduating of McComick Theological Seminary, he was nominated as a pioneer of Pyeng Yang Mission Station and set foot in Korea, September of 1892. Since then he started to erect missionary facilities in Pyeng Yang, such as Well House(1898), Pyeng Yang Central Church(1900-1901), Pyeng Yang Academy(1902). These all his works are designed with eclectic style which shows western and Korean traditional style intermingled. This unique characteristic made a profound influence to the Korean mission architecture afterwards. Especially, the L-type plan of Pyeng Yang Central Church, which is first shown by him, is recognized very unique, and this plan type had been spread all over the country. Therefore the L-type plan became the peculiar feature of the early Korean churches. Furthermore, working with Korean carpenters, he taught them new skills of modem buildings. After that, they were expanded out northern part of Korea and took the roles of master builders. According to this expansion, his particular style had got spread and had been settled as a unique eclectic style in Korean modern architecture. In the conclusion, he is evaluated to be a critical pioneer missionary, who left a big influence on the frame work of Korean modern architecture in the transitional times.

This study contains the process of developing a Mission Planning System (MPS) of an USV that can be applied in real situations and verifying them through HILS. In this study, we set the scenario of a single USV with limited operating time. Since the USV may not perform some missions due to the limited operating time, an objective function was defined to maximize the Mission Achievement Rate (MAR). We used a genetic algorithm to solve the problem model, and proposed a method using a 3-D population. The simulation showed that the probability of deriving the global optimal solution of the mission planning algorithm was 96.6% and the computation time was 1.6 s. Furthermore, USV showed it performs the mission according to the results of the MPS. We expect that the MPS developed in this study can be applied to the real environment where USV performs missions with limited time conditions.

The future battlefield operation concept does not focus on advanced and complete weapon systems, but requires a new battlefield operation concept that can effectively demonstrate offensive power by combining a large number of low-cost, miniaturized weapons. Recently, research on the autonomous application of major technologies that make up the mission control system is actively underway. However, since the mission control system is still dependent on the operator's operating ability when operating multiple robots, there are limitations to simply applying the automation technology of the existing mission control system. Therefore, we understand how changes in operator capabilities affect multi-robot operation and propose an adaptive mission control architecture design method that supports multi-robot integrated operation by adjusting the level of autonomy of the mission control system according to changes in operator capability.

With the development of robot technology, the expectation of autonomous mission operations has increased, and the research on robot control architectures and mission planners has continued. A scalable and robust control architecture is required for unmanned surface vehicles (USVs) to perform a variety of tasks, such as surveillance, reconnaissance, and search and rescue operations, in unstructured and time-varying maritime environments. In this paper, we propose a robot control architecture along with a new utility function that can be extended to various applications for USVs. Also, an additional structure is proposed to reflect the operator's command and improve the performance of the autonomous mission. The proposed architecture was developed using a robot operating system (ROS), and the performance and feasibility of the architecture were verified through simulations.

오늘날 개발되는 항공전자 시스템에서는 연합 구조(Federated Architecture)를 기반으로 전자장치들이 각각 하나의 소프트웨어 모듈이나 응용 프로그램을 수행하고 있으며 이들은 네트워크를 통해 연결된다. 이러한 연합 구조는 전체 시스템을 매우 복잡하게 하며 SWaP(Size, Weight and Power) 문제를 일으킬 수 있다. 본 논문은 이러한 문제가 특히 심각한 소형 무인 항공기에서 ARINC 653이 정의하고 있는 파티셔닝 기술을 활용하여 여러 임무 소프트웨어를 통합 운영하고 SWaP 문제를 효과적으로 해결할 수 있음을 보인다. 본 논문은 특히 실제 헥사콥터와 쿼드콥터에 통합 임무 시스템을 탑재하여 시험 비행을 성공적으로 수행했음을 보인다. 본 연구를 통해서 제시되는 통합 임무 소프트웨어를 운영하기 위해서 필요한 소프트웨어 기술과 통합 방법론은 SWaP이 중요한 다양한 실시간 시스템에 응용될 수 있다.
