Technical approach on the modeling, simulation and experimentation methods, which are applied for developing a constructive simulation and engagement experimentation software for supporting light weight torpedo operational tactics study, is introduced. Conceptual modeling for the weapon engagement and simulation entities, mathematical models for the simulation elements, approach for the design of experimentations are described, and screen shots of the software are also presented as some example results of experimentation and analysis. It is found that the simulation and experimentation results are useful to support and fulfill the mission needs and requests. As a consequence, the technical approach is rated to be appropriate to accomplish the dedicated purpose of the simulation and experiments.

This paper introduces experimental design and components model for analysing the impact of parameter(in the field of kinematics and sensor) on performance of hard-kill torpedo defence system. The simulation is implemented at the level of engagement and its scope is limited to final stage of engagement where main function of anti-torpedo system is operating. It improves the fidelity of physical realism by precise model of simulation components in the perspectives of kinematics, sensor capability and acoustic detection theory. This paper provides the experimentation methodology for evaluating parameter sensitivity which is required to analyze in advance of development the defense system with novel concepts. In addition, the experimental result shows the tendency of defense capability according to parameter adjustments.

This study was conducted to empirically analyze the impact of issue leadership and learning agility on the innovation behavior of startup employees. Issue leadership was subdivided into issue creation, audience engagement, and issue execution. Learning agility was subdivided into five factors: feedback seeking, information orientation, reflection, experimentation, and agility. The survey was conducted among employees working in startups. In this study, 300 valid surveys were analyzed. Hierarchical regression was used to test the hypotheses. The results of the empirical analysis were as follows Among the sub-factors of issue leadership, issue creation, audience engagement, and the sub-factors of learning agility, information orientation, reflection, experimentation, and agility had a significant positive effect on startup employees' innovation behavior. On the other hand, issue execution, a subcomponent of issue leadership, and feedback seeking, a subcomponent of learning agility, did not have a significant effect on innovative behavior. In addition, the magnitude of the effect on innovative behavior was in the order of experimentation, agility, issue creation, information orientation, audience engagement, and reflection. Therefore, this study on the effect of issue leadership and learning agility on innovative behavior concludes that issue creation, audience engagement, information orientation, reflection, experimentation, and agility play an important role.

Exploiting models and simulations are encouraged among the defense acquisition society, as now enforced by the Defense Aquisition Program Administration's regulations. They are useful and, sometimes, inevitable especially in an earlier phase of system development. Computer-simulation-based experimentation technique for the system operational performance analysis for a torpedo defense system is introduced in this paper. Problem definition for the torpedo defense system analysis and engineering efforts for models and simulations development are presented here, including defining measures of performance and effectiveness for the torpedo defense system, conceptual modeling for torpedo engagement and defense simulation, design of experimentation, design of simulator and experimentor, and hardware and software implementation of an analysis support tool - a system operations demonstration and experimentation simulator.

M&S in the field of national defense is a battle system has been highly spotlighted for obtaining weapon systems, analyzing and experimentation of battle effects to reduce costs, time, and risks. It is classified as Campaign, Mission, Engagement, and Engineering levels by detail of description. In engagements, many situations on the battle field which are really unpredictable are required to be considered on the view of diverse tactics. Thus, engagement simulation is in demand to use for forecasting real-world battle situations by inserting various components which consists of real engaging situations into virtual local battle field. While developing the engagement simulation, adopting the concept of agent-based simulation gives it benefits which are improved autonomy, composability, and reusability of entities. It means reducing the time, cost and effort to develop the simulations. This paper concentrates on the framework of multi-agent based engagement simulation using Cougaar Architecture.

The Korean naval weapon systems, combat experiments establish the concept of Battle operations, and create the future of the new weapons system. Doctrine development and training as well as ranging from experiments for evaluate the performance of mission operations for combat experiments are used. The battle lab is effectively support tool for the Korean Naval battle experiments. The battle lab is through a dedicated testing facility and to build efficient and effective simulation-based acquisition supporting environment. In this paper, the ship / submarines C2 operations virtual simulator was developed to support the concept of Battle operations of naval combat experiments in training and tactical development. The ship C2 operations virtual simulator makes the anti-ship and anti-aircraft the engagement scenario for performed experiments using the SADM. The submarines C2 operations virtual simulator makes the anti-submarine engagement scenario for performed experiments using EAS. EAS System was created before reuse. EAS system by modifying the additional interfaces HLA-RTI has been reused. Reflected in the tactics and training after analysis of the results through the battle experiment. Also increase training fidelity through operator involvement. The anti-ship and anti-aircraft system architecture (SADM) and anti-submarine system architecture (EAS) requires unique design of system framework since two separate architectures should be integrated into a system. An C2 virtual linked architecture was used to integrate different system architecture. A C2 virtual linked software framework, designed that have integrated protocol for battle experimental linkage and battlefield visualization environment.

This study explored, through informal, conversation-type interviews, how college students relate to science in general as well as to two specific socioscientific issues: human cloning and animal dissection/experimentation. How students "relate" includes what kinds of attitudes they have toward science and socioscientific issues, how seriously they consider and want to engage with these issues, and how they express their opinions or make a decision. The sample (16 college students) was heterogeneous in terms of academic background, ethnicity, and school year. Each interview lasted for about one hour with audiotaping. Results indicated that most participants immediately brought in their own values and feelings in implicit or explicit ways. However, the depth of their personal engagements varied. Most of the participants either did not take socioscientific issues seriously or merely quoted their own values in resignation, seemingly not able to deal with the issues and overwhelmed by many other aspects of the issues. By reflecting on the participants' reactions, the discussion addresses some of the larger issues for current secondary science teaching that involve raising responsible democratic citizens.
