돼지는 사육규모간 역할 분담을 유도하여 대규모 양돈업테에 대하여는 수출에 주력토록 함으로써 수급조절 및 가격안정을 도모하고, 부.전업규모는 국내공급을 위주로 하여 규모간 균형 발전을 도모해 나갈 계획이다

The elevator is extreme important due to the large size of the building and public facilities. In particular, it occurs bottleneck phenomenon in a elevator in case of using a theater. So, in this paper, we suggests technology of removing the traffics of visitors' movement and increase the efficiency of the use of elevator. Configuration of the proposed technique is divided parts of the processing unit, the movement route of the mobile cover to help viewers to create a route to collect sensor and the sensed data to detect state and a waiting elevator. This was the design and verification of technical performance and implementation.

The megastructure combined with the modular concept is an effcient structural system adequate for ultra-tail buildings for the future. An ingeneous structural control system can be developed by separating the internal subframe in one or many modules from the external megaframe, thus taking advantage of the effect of tuned mass dampers without adding any aditional mass. This so called mega-subcontrol system is generally modeled by a 20DF system for parametric study and for finding optimal values of the parameters. In this study the equation of motion for the system is obtained frist and the preconditions for the simplified modeling are investigated. Finally the optimal value for the subsreucture strffness is fomputed with given mass and damping ratios and transfer functions for responses are abtained for white noise ground exitation to verify the effectiveness of the mega-subcontrol system.

Tuning of the speed controller in the linear servo applications needs the accurate information of a mover mass including a load mass. Therefore this paper proposes the mass estimation method of a permanent magnet linear synchronous motor(PMLSM) applied at the vertical axis by using the recursive Least-Squares estimation algorithm. First, this paper derives the deterministic autoregressive moving average(DARMA) model of the mechanical dynamic system used at the vertical axis. The application of the Least-Squares algorithm to the derived DARMA model gives the mass estimation method. Matlab/Simulink-based simulation and experimental results show that the total mover mass of a PMLSM applied at the vertical axis can be accurately estimated at both no-load and load conditions.
