본 시험은 제주도에서 재배되고 있는 제주재래 등 총 6품종을 공시하여 피 품종 간의 생초 및 건물수량과 사료가치 등을 조사 분석하여 간척지에서 최적 사료용 피 품종 선발을 위한 기초 자료를 얻기 위해 충청남도 당진군에 소재한 대호간척지에서 1년간 수행하였다. 출현율은 겸용인 Summer green 품종이 95.0%로 가장 높았다. 생초 및 건물수량은 Summer green 품종이 각각 21,444㎏/ha와 5,296.5㎏/ha으로 가장 높았다. 조단백질 함량은 Shirohie (18.22%) 품종이 가장 높았다. TDN 함량은 Siberian 품종이 가장 높았으며 Panorama 품종이 가장 낮았다. 결과적으로 간척지 토양에서 사료용 피 재배 시 출현률, 생초 및 건물생산성 그리고 사료가치 등을 종합하여 고려할 때 겸용인 Summer green 품종이 가장 우수하였다. To select the forage millet variety suitable for cultivation in the reclaimed tideland, forage yield and feed value were compared for six millet cultivars grown at the Dae-Ho reclaimed tideland, Korea, from March to October in 2004. The emergency rate of summer green was 95.0% which was more than those of any other vatieties. Fresh and dry matter yield of summer green were 21,444 and 5,296 ㎏/ha that were more than those of any other vatieties. respectively. The content of crude protein was the highest in Shirohie variety as 18.22%. TDN (total digestible nutrient) content was the highest in Siberian variety and the lowest in Panorama variety. Considering the emergency rate, forage production and feed value, Summer green was the most suitable variety in reclaimed tidelands.

While the future warfare is expected to be appeared as network-centric, effect-based, and coordinated cooperative, most current M&S systems reflect only the unit behaviors and interactions of each weapon system. There are limitations to analyze the behaviors of managing weapons cooperatively and sharing the situational awareness over the networks of distributed sensors, C2, and shooters using them. Therefore, we introduce the new design of the networkcentric warfare modeling system using the agent-based modeling and simulation approach. We have developed a system for engagement-level warfare models and tested with multi-platform battleship warfare. In this paper, we propose the method to design battle agents, environments, and networks for network centric warfare modeling.

Gartner"s hype cycle, introduced in 1995, characterizes the typical progression of an emerging technology from overenthusiasm through a period of disillusionment to an eventual understanding of the technology"s relevance and role in a market or domain. In this paper, we present the dynamic mechanism underlying the related behaviors of the Gartner"s hype cycle by introducing the simulation technique for system dynamics, an approach to understanding the behavior of complex systems over time. Constructed by component-wise method, minimal model of hype cycle provides us with understanding crucial behaviors in terms of the expectation and the development of an emerging technology with parameter variation. The analysis derived from this paper allows both technology planners and enterprises to use it as a touchstone for business strategic decision-makings. Moreover, this model can be applicable to gain insight into other systems showing similar behaviors.
