With the recent advancements in artificial intelligence(AI) technology and the development of edge AI devices capable of processing AI workloads, software-defined cameras(SDCs) have been widely utilized in various video analysis services. However, as the number of deployed SDCs continues to grow, the complexity and cost of managing not only the cameras themselves but also their core components-edge AI devices-have emerged as significant challenges. To address these issues, this paper proposes and implements an Over-the-AIr(OTA)-based edge AI device management system designed to improve the operational efficiency of edge AI devices and enhance the performance of the services they provide. The proposed system supports remote updates and management of AI models and service applications, enabling efficient mAIntenance without requiring physical access to the devices. Furthermore, it periodically collects device status information to support real-time monitoring of operational conditions and provides all management features through an integrated, user-friendly Web-based graphical user interface(GUI). The system was implemented using Nvidia Jetson Orin Nano-based edge AI devices and a desktop-based integrated control server. Functional verification through practical deployment confirmed the successful operation of all designed components.

함정전투체계의 필수 CSCI(Computer Software Configuration Item) 중 하나인 체계관리 CSCI 소프트웨어는 타 CSCI보다 함형 별 기능 요구사항 변경이 자주 발생한다. 빈번한 요구사항 변경은 소프트웨어의 완전한 재사용을 어렵게 만들고, 신규 함형 개발 시 소스 코드 수준의 재사용을 반복하게 한다. 그리고 이러한 구조적 환경은 비효율적인 공수 활용에 따른 개발 시간 및 비용 증가를 일으키는 원인이다. 이를 개선하기 위해 본 논문에서는 체계관리 CSCI 소프트웨어의 재사용을 높이기 위한 모듈화를 적용하였다. 모듈화 적용의 수단으로는 표준화의 용이성과 기능 확장성의 장점이 있는 표준 연동 아키텍처 방법을 활용하였다. 비교 평가 방법으로는 체계관리 CSCI 소프트웨어 모듈화 적용 전/후의 기능 요구사항 수정 시 변경되는 클래스 비율의 비교, 그리고 소프트웨어 신뢰성 시험의 수행 시간 비교 등의 실험 평가를 수행하였다. 이러한 실험 결과를 통해 본 논문은 체계관리 CSCI 소프트웨어의 모듈화 적용 시 기존보다 높은 유지보수성과 재사용성을 가짐을 검증하였다.

Frequently changeable functional requirements in System Management CSCI Software make it difficult to reuse an overall application, but only the partial class codes repeatedly as a new version of Naval Combat Management System is developed. This structural environment leads to increasing development time and expenses. This is why modularization for System Management CSCI Software is proposed as a solution, leveraging the advantages of proper standardization and functional expandability offered by Standard Interface Architecture. This paper outlines the comparisons of modified class ratios as well as software reliability test runtime results between before and after implementing the modularization for System Management CSCI Software. The findings demonstrate there is sufficient improvement in areas, such as higher maintenance and reusability, supporting the application of modularization for System Management CSCI Software with the implementation of Standard Interface Architecture.

체계지원 소프트웨어는 함정 전투관리체계를 구성하는 소프트웨어 중의 하나로 모든 함정의 전투관리체계에 탑재되지만 기능 변경이 거의 일어나지 않는 특성을 가진다. 하지만, 이러한 특성에도 실제로는 신규함정 적용 시 장비 변경 등으로 인한 소프트웨어 수정이 불가피하게 이루어진다. 이러한 소프트웨어의 수정은 소프트웨어 신뢰성 시험 등의 작업을 초래하며, 개발 비용 증가의 핵심요인으로 작용한다. 본 논문에서는 기존 체계지원 소프트웨어의 구조를 분석하여 이를 보완할 수 있는 체계지원 표준화 아키텍처를 설계하였다. 휘처 모델(Feature Model)을 통해 체계지원 소프트웨어의 공통요소와 가변요소를 도출하고, 화이트 박스 재사용(White-Box Reuse)을 적용하여 소프트웨어 설계를 개선하였다. 또한, 기존 체계지원 소프트웨어와 개발 요소 및 신뢰성 시험 수행 시간을 비교하여 새로운 아키텍처의 효과성을 검증한 결과를 제시하였다.

System support software is one of the software that makes up ship combat management system and has the characteristics of being mounted in the combat management systems of all ships but with little functional change. However, despite these characteristics, software modifications due to equipment, etc. are inevitable in the application of new ships. Modification of software causes software reliability testing which is a key factor in increasing development costs. In this paper, the structure of the existing system support software was analyzed to identify and supplement the code change factors, and the system support standardization architecture was designed. The feature model elicited common and variable elements of system support software, and applied white-box reuse to improve software design. In addition, the results of comparing existing system support software with the new architecture in terms of development elements and time to perform reliability test were presented to verify the effectiveness of the new one.

Since software development team members have been more geographically spread due to the globalization of business and Internet technologies, the management of deliverables and communication efforts for developing high-quality software products on time is becoming more complicated. Among the functional requirements for collaborative software development management, the manipulation of shared information objects is essential for the collaborative work among distributed development team members. This paper proposes an integrated information object management framework comprised of a so-called BOC (Bill Of Class) scheme and a standardized software part dictionary for managing shared information objects efficiently among distributed co-workers. In order to manage these complex information objects, the proposed framework adopt product structures represented by Bills Of Materials (BOM) as stems for integrating the various information objects. Based on the proposed framework, a collaborative software development management system (CSDMS) is implemented, and the functionalities and the structure of the system are also described in this paper. The proposed system provides sufficient functionalities for the change management of information objects and the management of their relationship to other objects rather than existing system.

In this paper, we propose system access control software that improves the survivability of the naval combat system while maintaining security and stability. The software was improved by improving the operating environment configuration and user authentication process of the system access control software that constitutes the naval combat system, defining the operating environment classification of the naval combat system, and applying a software parallel execution process considering the load rate. Through this, the waiting time required to configure the environment is shortened, providing rapid operation to the operator, and improving the fact that the naval combat system cannot be operated unless the environment configuration is completed even in emergency situations. In order to test the performance, a test environment was created by simulating the existing naval combat system, and the execution time for each operation category was measured and compared. Compared to the existing naval combat system, the execution time of the basic combat system was reduced by about 69.3%, the execution time of the combat system was reduced by about 54.9%, and the execution time of the integrated combat system was confirmed to be reduced by about 8.4%.

DSS와 UDP 프로토콜을 통하여 메시지를 송/수신하던 기존의 방식을 Packet Sniffing으로 변경함으로써 메시지에 대한 의존성을 줄였으며 팩토리 메소드 패턴(Factory Method Pattern)을 적용하여 소프트웨어 설계를 개선하였다. 기존 소프트웨어와 개발 요소를 비교하는 시험을 통해 소프트웨어의 수정 용이성과 재사용성이 향상 된 것을 확인하였다.

The IISS(Integrated Interface Storage System) software uses communication methods such as DSS(Data Sharing Service), UDP to perform the function of sending all messages from the Combat Management System to the analytical computer. Because IISS software handles all message used in the Combat Management System, the source code is large and has a highly dependent feature on message changes. Modification of software is a task that requires a lot of labor, such as series of software reliability test. so research has been conducted to reduce software development costs, including minimizing software modifications. In this paper, We study the method of messages receiving and architectural structure improvement to minimize reliance on message changes in the Combat Management System and improve the modifiability. Reduced message dependency by changing the way DSS and UDP protocols are communicated to Packet Sniffing. In addition, Factory Method Pattern were applied to improve the software design. Test comparing existing software and development elements have confirmed that the software has improved its modifiability and reuse.

정보저장 소프트웨어는 함정전투체계의 연동 분석을 위해 전투 관리체계의 전술 도메인 메시지를 분석 컴퓨터로 전달하는 기능을 수행하며, 전투 관리체계와 분석 컴퓨터 간의 중간 매개체 역할을 한다. 정보저장 소프트웨어는 전투 관리체계에서 사용하는 대부분의 메시지를 처리하기 때문에 소스 코드의 양이 상대적으로 많고, 연동 장비 및 메시지의 변경 사항에 의해 수정 사항이 빈번하게 발생한다. 이에 따라 개발 과정에서 추가적인 공수가 소요되게 되고, 결국 개발 비용의 증가로 이어지게 된다. 본 논문에서는 재사용성을 향상하기 위하여 정보저장 소프트웨어 구조에 대한 표준화에 관한 연구를 수행하였다. 휘처 모델을 통해 정보저장 소프트웨어의 구성 요소를 기능별로 나누어 수정 요소를 분리하고, 디자인 패턴을 적용하여 정보저장 소프트웨어의 구조를 개선하였다. 그로 인해 연동 장비와 메시지의 변화에도 정보저장 소프트웨어의 수정 사항을 최소화할 수 있게 되어 개발 비용의 절감 효과가 기대된다.

The IISS(Integrated Interface Storage System) software performs the function of transmitting tactical domain messages of Combat Management System for interface analysis of Naval Combat System. The source code is relatively large because the IISS software handles most messages. The modifications of source code of the IISS software occur frequently due to changes in interconnected equipment and messages. Therefore, additional effort and cost are required during the development process. In this paper, we studied standardization of the IISS software to improve reusability. Through the feature model, the components of the IISS software were divided by function and modification elements were separated. And the structure of the IISS software was improved by applying design patterns. As a result, it was possible to minimize modifications of the IISS software by changes in interconnected equipment and messages and a reduction in development costs could be expected.

The application of software engineering is not common in the development of astronomical observation system. While there were component-wise developments in the past, large-scale comprehensive system developments are more common in these days. In this study, current methodologies of development are reviewed to select a proper one for the development of astronomical observation system and the result of the application is presented. As the subject of this study, a project of operation software development for an astronomical observation system which runs on the ground is selected. And the output management technique based on Component Based Development which is one of the relatively recent methodologies has been applied. Since the nature of the system requires lots of arithmetic algorithms and it has great impact on the overall performance of the entire system, a prototype model is developed to verify major functions and performance. Consequently, it was possible to verify the compliance with the product requirements through the requirement tracing table and also it was possible to keep to the schedule. Besides, it was suggested that a few improvements could be possible based on the experience of the application of conventional output management technique. This study is the first application of the software development methodology in the domestic astronomical observation system area. The process and results of this study would contribute to the investigation for a more appropriate methodology in the area of similar system development.
