In this paper, we propose the industrial controller with multi-function/multi-purpose in order to cope with a small-amount and large-items environments. The controller designed consists of Main Unit including all of information and Display Unit. The software in the Main Unit is composed of tasks and device drivers and each task is being processed in parallel by operating system supporting multitasking. The controller is structured in three levels to promptly address the control algorithm’s modification, MMI’s change, and so on. We can produce a controller without changing the first layer(hardware) and the second layer(firmware). We only modify the third layer(control algorithm) depending on control targets.

고품질 쌀 생산을 위하여 우리나라의 농가 및 미곡종합처리장의 벼 수확후 품질관리 현황 실태를 조사하여 일본, 미국, 중국 둥의 현황과 비교하였다. 중국의 경우 벼 수확은 대부분 인력에 의존하고 있으며, 일본은 산물형 콤바인 그리고 미국은 대형산물 콤바인에 의한 적기수확을 하고 있다. 우리나라의 경우에는 콤바인이 부족하고 벼 수확시기는 콤바인 운영자의 일정에 따라 결정되고 있으며 습논, 소면적 재배 논은 수확이 늦어져 적기 수확이 못되고 있는 실정이다. 한편 일본은 라이스센터, 컨트리엘레베타, 드라이스토아 등의 지원으로 적기 수확이 가능하고 건조기 건조율도 90%이상 2단계 상온 통풍체계로 수분함량 14.5~15.5%를 유지하고 있다. 우리나라를 제외한 일본, 중국, 미국의 저장시설은 대부분 대형저장 사이로에서 품종별, 산지별, 등급별로 구분한 저온저장 시스템을 갖추어 품질을 유지하고 있었다. 또한 도정시설도 고품질 도정시설을 완비하고 있으며 제현이나 정미과정에 색채선별기, 금속검출기, 활성화 장치 및 입형분리기 등을 통하여 불완전미가 제거하는 등 수확후 관리에 철저를 기하고 있다. 쌀의 등급화 및 유통과정를 보면 일본, 중국, 미국 등은 대부분이 품종, 산지 및 등급별로 브랜드화 하여 차별화 된 가격으로 판매되고 있으며 포장지에 쌀에 대한 정보를 최대한 표시하여 소비자가 선택하는데 도움이 되게 하여 유통되고 있다.

Since October 2006, number of deliberations of arcade game in Game Rating Board (GRB) annually was more than 1,000 cases except 2007 and 2010. However, these cases excessively handle to deliberate the game rating. Especially, the rating is manually performed thus, hindering the consistency and objectivity of the deliberation. To resolve this problems, we think that the automation of technical deliberation is necessary for arcade game which is needed to have much time for deliberation. The purpose of this study is to identify what the possibility part of automation or what obviously part of automation in the deliberation of game rating. To achieve our research purposes, we conducted in-depth interview with GLI standardization expert in BMM Korea and person in charge for deliberation in game rating board. The interview results show that 12 standardization and 14 automation factors for deliberation in game rating of arcade game. This study will expect bases in game development and promotion in game industry.

In the past, the scenario of VTS simulator was made by instructor's manual operation using waypoint definition of target ship. but in this study, we use automatic scenario creation technology with AIS data and Port-MIS data. The created VTS simaulator scenario also can be modified, added, and saved by instructor's manual operation. VTS simulator display target ship on the Electronic Navigation Chart based on S-57 format. A instructor can easily open this scenario and start, pause, stop operation wirth VTS simulator. A new modification also can be applied immediately to current scenario and can be saved new scenario file. VTS simulator using this technology can create many scenarios for a specific purpose and can be easily used for various application fields.

In this paper, we introduce an application-specific and adaptive power management technique for portable systems that support dynamic voltage scaling (DVS). We exploit both the idle time of multitasking systems running soft real-time tasks as well as memory- or CPU-bound code regions. Detailed power and execution time profiles guide an adaptive power manager (APM) that is linked to the operating system. A post-pass optimizer marks candidate regions for DVS by inserting calls to the APM. At runtime, the APM monitors the CPU's performance counters to dynamically determine the affinity of the each marked region. for each region, the APM computes the optimal voltage and frequency setting in terms of energy consumption and switches the CPU to that setting during the execution of the region. Idle time is exploited by monitoring system idle time and switching to the energy-wise most economical setting without prolonging execution. We show that our method is most effective for periodic workloads such as video or audio decoding. We have implemented our method in a multitasking operating system (Microsoft Windows CE) running on an Intel XScale-processor. We achieved up to 9% of total system power savings over the standard power management policy that puts the CPU in a low Power mode during idle periods.

Recently, as the growth of the wireless Internet, PDA and HPC, the focus of research and development related with GIS(Geographic Information System) has been changed to the Real-Time Mobile GIS to service LBS. To offer LBS efficiently, there must be the Real-Time GIS platform that can deal with dynamic status of moving objects and a location index which can deal with the characteristics of location data. Location data can use the same data type(e.g., point) of GIS, but the management of location data is very different. Therefore, in this paper, we studied the Real-Time Mobile GIS using the HBR-tree to manage mass of location data efficiently. The Real-Time Mobile GIS which is developed in this paper consists of the HBR-tree and the Real-Time GIS Platform HBR-tree. we proposed in this paper, is a combined index type of the R-tree and the spatial hash Although location data are updated frequently, update operations are done within the same hash table in the HBR-tree, so it costs less than other tree-based indexes Since the HBR-tree uses the same search mechanism of the R-tree, it is possible to search location data quickly. The Real-Time GIS platform consists of a Real-Time GIS engine that is extended from a main memory database system. a middleware which can transfer spatial, aspatial data to clients and receive location data from clients, and a mobile client which operates on the mobile devices. Especially, this paper described the performance evaluation conducted with practical tests if the HBR-tree and the Real-Time GIS engine respectively.
