In the recent trend of electric power supply market, a variable pressure operation supercritical once-through steam generator is highlighted as a thermal power plant for cycling load because of its superiority in load regulation. Almost all thermal power plants of the future are expected to be variable pressure operation supercritical once-through units. APESS(Advanced Plant Engineering & Simulation System) is a dynamic simulation software for power plant which is under being developed by Korea Heavy Industries & Construction Co., Ltd. This paper present the introduction of APESS and the result of simulation for variable pressure operation supercritical once-through steam generator.

In this paper, a computer software for dynamic analysis of a high mobility tracked vehicle with pre/post processor is developed. Model of a tracked vehicle is composed of chassis, turret, mount, gun, and road-wheel assembly. Track is modeled as an extensible cable and the track tensions are applied on the wheels as external forces. The system equations of motion and constraint acceleration equations are derived in the joint coordinate space using the velocity transformation method. The pre and post processors are developed using the Visual C++.

Recently, a name retrieval function is widely used on navigation systems. In this paper, we propose the new dynamic hashing algorithm for a name retrieval function on it. The proposed dynamic hashing algorithm by constructing an index using the variance information of character is the better than existing methods in terms of storage capacity and retrieval speed. The algorithm proposed in this paper can be useful on systems that have limited resources as well as navigation systems.

최근 무기체계에서 소프트웨어가 담당하는 기능이 많아지고, 복잡해지면서 소프트웨어의 품질의 중요성에 대해서 대두가 되고 있다. 소프트웨어의 품질요소는 기능성, 사용성, 유지보수성, 신뢰성이 있으며, 이중 최근 들어 중요시되는 항목이 신뢰성 분야이다. 신뢰성 시험은 분석을 통한 정적 시험과 수행을 통한 동적 시험방법이 있으며, 실수행을 통해 검증하는 동적시험은 정적시험에 비해 많은 기간이 필요하며 복잡성이 높아질 경우 더욱 증가되는 경향을 보인다. 본 논문에서는 다기능 레이더 소프트웨어 개발시 수행한 신뢰성시험 절차 및 결과를 기술하고 이를 통해 효과적으로 시험기간을 줄일 수 있는 신뢰성시험 방법을 제안한다.

This study was conducted to find out effect of dynamic balance performance in normal adult when obscuring vision in half of the both eye and to prepare the basic data treatment of brain damage patient with visual field deficit. The subject for this study included 40 healthy right-handed and 20 left-handed were dynamic balance performance when obscuring vision in half of the both eye. who age from 20 to 30 years in normal adult without neurosurgical orthopedic, performance balance disability or other medical disorders. Of these individuals 20 right-handed and 20 left-handed were executed dynamic balance performance when obscuring vision in half of the both eye. individuals of right, left-handed were executed dynamic performance when obscuring vision in half of the both eye measure with a Balance Performance Monitor (BPM) Data print Software Version 5.3. In other to determine the statitsical significance of the result, instrumentation was used to t-test, chisquare of the SAS(Strategic Application Software) The result of the study were that: 1) Significant differences in LOS were found right-handed and left-handed subject when dynamic performance without obscuring vision and obscuring vision(p<0.05). 2) Significant differences in LOS were founded left-handed when dynamic performance were executed obscuring vision and without obscuring vision(p<0.05). 3) Significant differences in LOS were founded right-handed when dynamic performance were executed obscuring vision and without obscuring vision(p<0.05).

Conventional static reliability analysis methods are inadequate for modeling dynamic interactions between components of a system. Various techniques such as dynamic fault tree, dynamic Bayesian networks, and dynamic reliability block diagrams have been proposed for modeling dynamic systems based on improvement of the conventional modeling methods. In this paper, we review these methods briefly and introduce dynamic nodes to the existing reliability graph with general gates (RGGG) as an intuitive modeling method to model dynamic systems. For a quantitative analysis, we use a discrete-time method to convert an RGGG to an equivalent Bayesian network and develop a software tool for generation of probability tables.

The purpose of this study is to design of a linear feeder using a multi body dynamic program, and to analyze a dynamic motion of the feeder that can transport small mechanical parts uniformly. In order to establish the analysis model of the linear feeder, each parts of the feeder are divided into two types which the rigid and flexible body. For the dynamic simulation, RecurDyn, which is a commercial multi-body dynamic package, is used. We also consider the design parameters for optimal dynamic motion such as centroid, stiffness, and mass of the feeder system. In order to analyze the dynamic motion of a linear feeder, the displacements of the feeder are measured by several accelerometers when it is in an operating condition. After the signal data from the accelerometers are captured in the time domain, the dynamic motion in the space is visualized by using graphic computer software.
