Unmanned Aircraft System(UAS) is a huge and complicated system that is composed of UAV, ground control system, datalink system, and mission equipments. We have applied system engineering to development of UAS. Configuration management is very important activity for efficient developments. The Configuration management process comprises four distinct disciplines (Configuration identification, Configuration control, Configuration status accounting, and Configuration audit). This paper explains the configuration management system of UAS development project which ADD executes and introduces several examples of these four disciplines.

Recently, great improvements have been made in developing autonomous underwater vehicles (AUVs) using stateof- the-art technologies for various kinds of sophisticated underwater missions. To meet increasing demands posed on AUVs, a powerful on-board computer system and an accurate sensor system with an well-organized control system architecture are needed. In this paper, a new control system architecture is proposed for AUV, ORCA (Oceanic Reinforced Cruising Agent) which is being currently developed by Korea Research Institute of Ships and Ocean Engineering (KRISO). The proposed architecture uses a hybrid architecture that combines a hierarchical architecture and a behavior based control architecture with an evaluator for coordinating between the architectures. This paper also proposed a sensor fusion structure based on the definition of 4 categories of sensors called grouping and 5-step data processing procedure. The development of the AUV, ORCA involving the system architecture, vehicle layout, and hardware configuration of on-board system are described.

Recently, deep ocean water (DOW), which is plentiful in the East sea, has been recognized a global resources for 21st century. To develop DOW resource of 300m deep at Gosung sea, the pipeline of about 4 km long is essentially required to establish land based model complex of DOWA techno-park at coastal zone. This study aims to establish design procedure of DOW supplying and utilizing systems, and to complete basic design of every major facilities. To design, various numerical analysis and engineering consideration have been studied by cooperative works for practical use.

This paper describes the verification and the validation about the development of the integrated interoperability system for live, virtual, and constructive simulations on the aircraft weapon system. The proposed integrated interoperability system provides the framework and application softwares for implementing a synthetic environment emulating real-world environment among distributed simulation models, which are a mission model and an air combat model of a constructive level, an tactical simulator of a virtual level, and simulated ACMI of a live level. In this paper, we verify requested functions through an developmental test and evaluation, and validate operability and usability through conducing integrated LVC scenarios on the integrated interoperability system.

This paper presents a structured framework for developing the embedded subsystem, called ESDMP (Embedded Subsystem Development Methodology for POP), which is one of core components at the development of POP (Point Of Production) system. It is essential that embedded subsystem development methodology must be closely related to the general information system development methodology from the early stage of system development. Therefore, this paper investigates the PDSM (Production System Development Methodology) that is developed by Korea Technology and Information Promotion Agency for SMEs and widely utilized at the fields of POP system development, and proposes the embedded subsystem development methodology aligned with each step of PSDM. The main characteristics of proposed methodology are as follows : First, it is developed to link each step of embedded subsystem development with relating steps of PSDM from the early stage of feasibility study. Second, it provides the procedure for designing and implementing hardware and software simultaneously. Third, it includes the method of reusability for developed products and modules.

This paper presents an efficient methodology for information system development by adopting the concept of extended components which can achieve the improvement of development productivity, reductrion of development time periods, quality improvement of information systems, etc. when information development projects are carried out. First of all, for efficient development of information systems, development steps of current methodologies for information system analysis are subdivided into components in detail and outputs required at each step are defined. The components are extended by types and various application methods are proposed in each step of information system development. In addition, a method which uses advantages of current methods such as SDLC, prototyping, and RAD, is also proposed. In this research, a CASE tool named S-Designer is used for the development of extended components and their interface, and a system development method called DSDM for the deviation of detailed steps and corresponding outputs.

There are found rare specific alternatives for sustainable rural development although sustainable development has become popular common concept in international development arena. Korea is trying to reform rural development by introducing a block grants system since 2009 expecting for the efficiency of development investment. However, it seems that such new rural development system is far from realizing the sustainable development. The objectives of the study are to identify the roles and issues of the sustainable development policy and to suggest a policy model for realizing sustainable rural development. Based on the policy model hypothetically established, some policy alternatives were suggested: (i) the establishment of land use system considering sustainability perspectives; (ii) the preparation of environment management measures considering topographical traits; (iii) the improvement of landscape support scheme toward increasing biodiversity; (iv) the systematic implementation of agriculture-environment measures; (v) the implementation of sustainable development projects linking production to housing; (vi) the inclusion of sustainability indicators in rural development evaluation system.
