The purpose of this paper is to suggest the methodology for the establishment of operational concept for speed-up of defense robot and improvement direction of the defense acquisition system for the defense robot. In order to achieve this goal, the current defense acquisition system was analyzed into long-term planning, mid-term programming, and project execution stages. And I suggest the methodology for the establishment of operational concept for speed-up of defense robot and direction of development of the defense robot acquisition system considering the characteristics of the robot in terms of core technologies of robot, robot ecosystem and effectiveness-based-robot-design, respectively. Based on the methodology for establishment of the operational concept of defense robot and development direction of the defense acquisition system presented in this study, it will be possible to design efficiently the defense robot in the future.

본 논문에서는 효율적인 암묵적 지식을 표현하기위한 도구로써 개념매핑기법에 대해 기술을 하고 있다. 개념매핑기법은 비형식적인 것에서부터 형식적인기법까지 다양하다. 형식적개념매핑은 사용이 용이하지만 컴퓨터 처리능력이 없다. 반면에 비형식적 개념매핑은 추론능력은 있으나 사용이 어렵다는 단점이 있다. 따라서 미래의 지식매핑시스템은 형식적ㆍ비형식적 개념기법의 장점을 모두 고려해야 할 것으로 보인다.

This study aims to verify experimentally the specifications of the data acquisition system required for the precise measurement of signals in an underwater explosion (UNDEX) experiment. The three data acquisition systems with different specifications are applied to compare their precision relatively on maximum shock pressures from UNDEX. In addition, a method of assessing the acquired signals is suggested by introducing the concept of measurement uncertainty. The underwater explosion experiments are repeated five times under same conditions, and assessment is conducted on maximum quantities acquired from underwater pressure sensors. It is confirmed that the concept of measurement uncertainty is very useful method in accrediting the measurement results of UNDEX experiments.

This paper relates to the improvement application of operation requirements documents(ORD) on which empirical researches are not sufficient. The application of ORD was drawn up and operated in the acquisition phase, and recently it was decided to apply it in the requirements planning phase. However, the reality is that there are deficiencies in the performance of works, such as the classification of works among related organizations. Therefore, this study analyzed the cases of writing ORD that have been promoted so far, and Its status was enhanced by reflecting it in laws and regulations. In addition, the concept was redefined, and improvement measures such as the level of writing ORD were suggested for each acquisition stages. Above all, it is desirable to incrementally supplement and develop from preliminary conceptual research in the planning stage and drafting at the military level. In addition, the relevant legal system should be supplemented so that such ORD application can be flexibly established in defence acquisition.

Purpose: This study was to evaluate the strengthening process of advanced beginner's nursing competence through the concept mapping methods. Methods: This study was conducted with focus group study for 1 month from November to December 2012 (n=5). Data were analyzed through open coding, axial coding and selection coding stage. Results: Advanced beginner to represent the experience of nursing empowerment and the three categories of the nine concepts were derived. The first category is 'able to see the entire search.' This concept is to start a search query, the search process of thinking, behavior change is expected. The second category is 'behavior change through the acquisition of knowledge.', and this concept is the embodiment of knowledge, confidence rising, and action changing. The third category is 'nursing empowerment', the aesthetic, ethical, and personal knowledge acquisition, as well as self-growth. Conclusion: Advanced beginner saw the full flow through the concept mapping and obtained knowledge, and changed behavior. Thus, the concept mapping is effective to strengthen the nursing competence.

The Systems Engineering method is increasingly recognized as a central in the Acquisition of Weapon Systems in South Korea. Because of these trends, issues concerned with improving weapon system design are increasingly raised. This paper presents a development of Operational Mode Summary/Mission Profile (OMS/MP) in terms of Weapon Systems Acquisition for application to Systems Engineering method. For a systematic approach, a precise concept of OMS/MP is derived by analyzing the concept of conventional OMS/MP. This paper reviews the results of a series of previously reported examples aiming to develop the OMS/MP of a weapon system. Based on this, the limitations of the conventional OSM/MP applications are investigated. And these limitations can be resolved by the Fundamentals of Systems Engineering. Finally, the OMS/MP framework based on the Fundamentals of Systems Engineering has been proposed and is successfully implemented for the Harbor Underwater Surveillance System.

Recently, request far application of advanced commercial technology to the defense acquisition process, to reduce the budget and shorten development time, has been increased. To accomplish these goals, the Advanced Concept Technology Demonstration(ACTD) is used for the defense acquisition process in Korea. And User Utility Assessment is tested to make a decision for transition to acquisition process. But this process does not include measurement of technology maturity and impacts of interface and interaction among the technologies. In this research, we propose the needs of measurement of TRL and IRL and application of SRL to reduce the risk during development phase, to understand the relations of technologies, and to fulfill the requirement far transition of the ACTD project to system development and demonstration process.

Korean Naval Ship acquisition processes are very complicate. There are 4 phases, Feasibility Study, Concept Design, Basic Design, Detail Design and Construction. A number of organizations and support groups exist to acquire naval war ships. Thus, It is very important how to establish traceability about requirements. This work has investigated how to improve traceability about requirements using Shipboard Work Breakdown Structure.

This paper investigates the current status of the acquisition of information resources at the domestic hospitals. First of all, as a theoretical background, the concept of hospital information systems and the acquisition of information resources are reviewed. Second, as a research methodology, samples, data collection methods, and data analysis methods are discussed. Third, research hypotheses, operational definitions of the research variables and measurement are discussed. Fourth, as research results, characteristics of the samples and the current situations of the acquisition of information rourses are discussed based on the five research hypotheses.
