Purpose: In the near future, it is expected that UGV(unmanned ground vehicle) will be put into battle due to IT technology and unmanned technology development. In this study, we analyze the combat effectiveness considering communication effect where complex combat information and commands are transmitted. Methods: We use ABM(agent-based modeling) and wireless channel module which provides sophisticated communication effect through geographic information and UGV performance. And UGV combat simulation using wireless channel module is used to grasp the combat effectiveness according to the number of packets, which is a unit for storing all information and commands having high complexity. Results: The result of this study is to derive the optimal number of packets which does not decrease the combat effectiveness and the number of lost tanks. The number of packet increases, the survival ratio of our tanks are decreased. Conclusion: In this study, we reveal that the communication success or failure could affect the combat effectiveness. Also, it helps develope the standard communication protocol between UGVs and could be applied to analyze the cost effectiveness analysis in UGV combat environment.

The enhancement of C2(Command and Control) system will increase effectiveness of individual force power in combat engagement. Especially, available time of a given engaging force and information accuracy are the most influencing factors to increment of combat effectiveness after enhancement of C2 system. In this paper, by using Schutzer's C2 Theory and Measures of Effectiveness, we developed several analytical functions representing the relationships between C2 system enhancement and two most critical variables, available time and information accuracy. As a result of functional analysis, we showed C2 system enhancement and combat effectiveness have positive and non-linear relationship. The higher level of C2 system be required, the better combat effectiveness of force power can be obtained. Additionally, we proposed a proposition that the combat effectiveness of C2 system is more sensitive to available time than to information accuracy, which might be very important issue for further research in this field.

The present study is aimed at evaluating the economic effectiveness of Abalone, haliotis discus hanai Releasing Project(ARP) conducted in the fishing ground owned by a fishing village in Ulsan, Korea. The results were summarized as follows: First, an average ratio of released abalones in the total landing after releasing is shown to be 85.0%. Second, the recapture rate of released abalones is 46.8%, exceeding the recapture rate of BEP(Break-Even-Point), 22.9%. Third, it is evaluated that total economic effectiveness of the ARP is 6.7-6.8 times, net effectiveness is 2.2-2.3 times, and the NPV(Net Present Value) discounted by a 8% interest rate is 474, 635 thousand wons, indicating the project is profitable. Considerable parts of the positive results on the ARP are based on some beneficial conditions, including the selection of favorable releasing sites, best self-regulation system of a fishing village for preservation of seaweed facilities and continued activities for protecting small abalones and their rearing. These results imply that the success of the ARP would be primarily dependent upon the selection of releasing site and effective management system after releasing.

In this study numerical and experimental studies are conducted to examine the wave screening effectiveness of trenches. The numerical study is based on a finite element model of a "sandbox" with Lysmer-Kuhlemeyer-type absorbing boundaries. Using the model, the screening effectiveness of trench is studied for different trench dimensions and distance from source and receiver to trench. The results of the numerical modeling are compared with the results of the ultrasonic experiment which is performed on a acrylic block with a drilled rectangular cut. These results show that the screening effectiveness of the trench is nearly equal if the depth of trench is lager than 60 % of the surface wave length. If is also shown that if the distance between the trench and the source is lager than twice the surface wave length, the thickness of the trench does not affect the screening effectiveness.

Ergonomic techniques have been required to analyze the effectiveness of functional clothing design improvement in a systematic and analytic manner. The goals of the present study are to: (1) comprehensively and analytically examine the effectiveness of clothing improvement by using the relationship analysis between clothing design components (D) and ergonomic evaluation measures (E) and (2) prove the usefulness of cost-effectiveness analysis for clothing design optimization. The cost effectiveness analysis is comprised of the preliminary evaluation based on expertise and the in-depth evaluation where the D-E relationship analysis is applied. As a result of the cost effectiveness analysis applied to flame-proof clothing, an optimal design was identified by analyzing costs and qualitative/quantitative effects. In the preliminary evaluation, the expected effectiveness of each design alternative on wear efficiency and wear comfort was estimated. In the in-depth evaluation, however, the effectiveness of each design alternative was analyzed by quantitative evaluation in a wearing test using a questionnaire prepared based on the D-E relationship analysis. It was concluded that the D-E relationship analysis and the cost-effectiveness analysis are useful for comprehensive evaluation and optimization of functional clothing design.

There is no absolute leadership through East and West. Just as past and present conditions are not the same, it is not easy for past leadership to apply to the present. The best leadership will be the leadership that can represent and lead the changing situation. In that sense, the creative leadership is the most appropriate leadership required by the present age. In the society, research on creative leadership is actively conducted in schools and companies, but there is no research on creative leadership in the military. This is the first study in the military about creative leadership. It is meaningful to understand the understanding of creative leadership and the applicability of the military and to provide a basis for future research. First, we measured the organizational effectiveness of creative leadership. The data were analyzed by factor analysis, correlation analysis, and regression analysis using SPSS 18.0. The results of this study were as follows. First, the organizational effectiveness of creative leadership and organizational goals and achievement were measured, and it was found that there was significant influence on the relationship between creative leadership and organizational effectiveness. I could confirm some. This would be meaningful in that it suggested the possibility of applying the leadership of the creative leadership to lead the change of society and to implement the military command.
