Evolutionary acquisition is an alternative to the grand design acquisition approaches. It has activities to make it possible to develop quickly and respond flexibly to changing customer needs and technological opportunities. The Ministry of Defense adopted an evolutionary strategy to acquire defense information systems. but it does not work well always. We look at problems from aspects of acquisition system and project management. We benchmark successful cases for evolutionary acquisition strategy in the DoD, the pubic and the private sector. We suggest an evolutionary strategy for defense information systems. The evolutionary strategy in this study includes an evolutionary acquisition framework, an evolutionary acquisition process, and an evolutionary acquisition guideline for defense information systems. The evolutionary strategy can help to implement evolutionary acquisition process for defense information system, and the process can increase the success rate of projects.

An EA(Evolutionary Acquisition) strategy is based on the systems engineering. It is a preferred approach to provide operationally useful capabilities to the warfighter much more quickly than single-step to full capability strategy. Recently, DoD is trying to apply the acquisition process based on the systems engineering. In spite of these trends, efforts of domestic defense acquisition society to this strategy are insufficient. Although an EA strategy has many benefits, there are many constraints to apply it. This study analyzes these constraints and presents applications of the EA strategy to defense R&D programs.

Define the importance and role of the acquisition strategy based on the Defense Acquisition Management System, diagnose and analyze the actual state of document preparation. We analyzed the timing and details of the basic strategy of the project in 2015 and suggested a supplementary plan to improve the efficiency of Military force improvement projects in conjunction with the Defense Planning and Management System. It is necessary to reduce the preparation period including the policy decision making process and then divide it into planning and programming stages to complement the role of acquisition strategy. In order to apply these improvements, the necessary revision of laws and regulations to be reviewed is referred to, enabling continuous research.

In this empirical study, we try to find major factors influencing the selection of technology acquisition strategy, and to examine the relation between technology acquisition strategies and corporate performances. The results of this study are as follows. Firstly, it is required to make intrinsic efforts for the harmony of technology acquisition strategies, which guarantees the effective acquirement of new technology. Secondly, we should pay particular attention to the harmony of external and internal resources for the corporate growth, Finally, the development of new technology is to be made on the basis of technology acquisition strategy established in terms of resources.

The purpose of this study is to analyze the effects of Critical Thinking Strategy supporting argumentation activities between learners. The research question is whether the form of Critical Thinking Strategy offered to support meaningful interaction of collaborative argumentation between learners influences the knowledge acquisition, learning outcome, and student satisfaction. For this, the collaboration outcome of the group, the level of individual knowledge acquisition, the level of students satisfaction were measured as outcome of argumentation activity and their differences analyzed. This study concludes the following: A comparison of the group that was provided with Critical Thinking Strategy (test group) and the group provided with general argumentation scaffolds (compared group) showed there wasn't statistically significant differences in the quality of the learning outcome of collaboration between the groups and in students satisfaction. But there was significant difference in the degree of individual acquisition depending on the offering of scaffolding for Critical Thinking. Therefore, as premised in this study, supporting meaningful mutual interaction between learners during collaborative argumentation using Critical Thinking Strategy has a positive influence on the individual acquisition of domain knowledge. The group provided with scaffolding for Critical Thinking gained higher effect in the degree of knowledge sharing and individual acquisition of domain knowledge compared to the group provided with general argumentation scaffolding.

In the field of information security management systems, one of the representative certifications in Korea is ISMS-P certification, and internationally, ISO/IEC 27001 certification is recognized. When companies acquire both ISMS-P (or ISMS) and ISO/IEC 27001 certifications, budget and manpower are duplicated in similar areas. Therefore, it is necessary for the company to choose and invest in a certification that is suitable for its conditions. This paper proposes a strategy for obtaining information security management system certification that is suitable for the characteristics of the company, allowing for effective information security management based on the company's conditions. To achieve this, data were collected from the Ministry of Science and ICT's Information Security Disclosure System (ISDS), the Korea Internet & Security Agency (KISA), and the Financial Supervisory Service's Data Analysis, Retrieval and Transfer System (DART), and Probit regression analysis was conducted. During the Probit regression analysis, the relationships between seven independent variables and five cases of ISMS-P (or ISMS) acquisition, ISMS-P acquisition, ISMS acquisition, ISO/IEC 27001 acquisition, and both ISMS-P (or ISMS) and ISO/IEC 27001 acquisition were analyzed. The analysis results revealed the relationship between company characteristics, including industry, and certification acquisition in the ISMS field. Through this, strategies for certification acquisition based on company types could be suggested.

Alternative binary offset carrier (AltBOC) signals can be approximated by four synchronized direct sequence spread spectrum (DSSS) signals, each pair of which is a quadrature phase shift keyed (QPSK) signal at a different frequency. Therefore, depending on the strength of an incoming AltBOC signal, an acquisition technique can reduce the mean acquisition time (MAT) by searching the four DSSS signals asynchronously; the search for each of the four DSSS signals can start at one of the evenly separated hypotheses on the two-dimensional hypothesis space. And detection sensitivity can be improved by multiple levels when different numbers of search results for the same hypothesis are combined. In this paper, we propose a fast AltBOC acquisition technique that has an asynchronous search strategy and efficiently utilizes the output of the four search results to increase the sensitivity level when sensitivity improvement is needed. We provide a complete theoretical analysis and demonstrate with numerous Monte Carlo simulations that the MAT of the proposed technique is much smaller than conventional AltBOC acquisition techniques.

이 글의 목적은 사회의 대사건이나 주요 공공 정책에 관한 기록화를 위해 작동되는 보존기록 시스템에 관한 논의이다. 필자는 세 가지를 제안하였다. 첫째는 기록이 만들어지는 같은 시대에 보존기록을 선별하는 기록화 전략의 개발이다. 여기에는 기록에 포함된 모습이 중요하며 여기에 가급적 넓은 사회적 맥락이 반영되어야 한다는 것으로, 필자는 이는 보존기록의 가치에 관한 사고의 전환에서 비롯된 것으로 보았다. 둘째는 그러한 전략에 해당하는 보존기록을 획득하기 위한 도구의 개발이다. 기록화 전략은 전략에 맞는 기록을 획득하는 별도의 방법을 필요로 한다는 것이 필자의 주장이다. 셋째는 이러한 기록화 전략과 기록 획득수단의 지속가능성이다. 이와 관련하여 필자는 현행 한국의 국가 아카이브 체제의 문제에 관해 논의하였다.

Under the fast technology changes and budget constraints, the organizations related to national defense face increased demands to develop innovative strategy and methodology to maximize performance with drastically reduced cost. In this context, the management of innovation and change in the defense acquisition area is vital to the Ministry of National Defense, related organizations and industries. In this paper, we discuss three comprehensive innovation strategies and methodologies for the defense acquisition area preparing for next-generation warfare; EVMS (earned value management system), PBL (performance based logistics) and SBA (simulation based acquisition). These collaborating innovative efforts enable us to tackle defense challenges for government and industries with a flexible and optimistic approach that maximizes productivity and performance with minimum cost.
