Next generation computer will have hardware support for digital "Continuous Media"(CM) such as audio and video. CM applications handle at high rate, with strict timing requirment. To run effienciently such application, an operating system must provide scheduling and IPC mechanism that reflect these needs. We propose that lightweight process to run effienciently mutiple address space, that is, user level scheduling of split-leve scheduling combines DMA scheduling by analysing multimedia data. These mechanism reduce kernel interaction and CPU overhead.

This study focused on the development of an alternative stress estimation procedure to instantly calculate the critical stresses bonded concrete pavement. Closed form analysis is commonly used to analyze pavement structures. This type of analysis assumes linearelastic material properties and static loading conditions. The well-known ILLI-SLAB finite element program was used for the analysis. Bonded concrete overlay analyzed the stress distribution, behavior and load carrying capacity under track load is made evaluation standard of bonded concrete overlay. In the study, the following results were derived; The properties of strength is that compress and 3-point bending strength of existing pavement is deteriorated with 184 kg/㎠, 59kg/㎠ but compress and splitting tensile strength of overlay is satisfied with 464 kg/㎠, 45kg/㎠. Load transfers is happen at adjacent slab by interlocking under track load. The stress distribution under interior, corner and edge load is described high loading position surrounding then loading position.

최근에 폴리프로필렌 섬유를 첨가하여 콘크리트의 인성을 증가시키고, 균열에 대한 저항성을 향상시키고자 하는 노력이 계속되어 왔다. 그러나 첨가된 섬유의 구조에 대한 이해부족으로 인하여 연구자들간에 실험결과에 대한 해석이 상이한 경우가 많았다. 이러한 연구의 일환으로 섬유의 첨가에 따른 건조수축 균열의 조절 가능성을 분석하기 위하여 섬유의 첨가에 따른 유동성과 건조수축의 변화를 조사하였다. 섬유의 첨가에 따른 유동성의 변화와 건조수축을 측정하기 위한 강제링 시편을 제작하였다. 본 연구에서는 섬유를 첨가한 콘크리트의 역학적 거동특성인 압축강도, 휨강도, 인성, 그리고 균열특성을 실험적으로 규명하고자 하였다. 본 연구는 강도 및 건조수축특성을 규명하기 위하여 수행되었고 섬유의 영향으로 인한 건조수축특성을 예견할 수 있다. Polypropylene Fibers have been used to increase the toughness of concrete and to increase the resistance to crack formation. However, there are many contradictory argument about the effectiveness of the fiber due to the lack of knowledge about the mechanism of fiber in concrete. In order to study the effect of fibers on possible crack control, the effects of fibers on workability and drying shrinkage have been studied. The workability change due to the addition of fibers has been studied, and full size concrete steel ring specimen have been cast at field to investigate the effect of fibers on the shrinkage properties. This laboratory have been performed to obtain the properties of pp fiber reinforced concrete such as compressive, flexural strength, toughness, slump, drying shrinkage crack and drying shrinkage characteristics. The present study was performed clarify the strength and drying shrinkage properties. From these results, we can expect the effect of the admixtures of polypropylene fiber for concrete and mortar about strength and drying shrinkage properties.

본 논문은 통행전 정보가 운전자의 경로선택에 미치는 영향을 연구하는데 있으며 통행전정보 제공에 대한 운전자의 경로선택을 분석하기 위하여 선호의식조사를 실시하였다. 통행전 정보로 대체경로에 대한 통행시간 정보를 사용하였으며 운전자의 경로선택행동을 분석하기 위하여 비집계분석모델을 이용하였다. 결과, 운전자의 사회ㆍ경제적 속성과 통행전정보가 운전자의 경로선택에 영향을 미침을 알 수 있다. The main purpose of this paper is to investigate the effects of pre-trip information for drivers' route choice. Stated preference survey is performed to analyze the drivers' route choice for pre-trip information. In this paper, the consuming time for alternative pass is considered as the pre-trip information. Descrete choice analysis is used to model the drivers' route choice behavior. As a result, it shows that social income attribute of the driver and the travel time with pre-trip information affect the drivers' route choice behavior.

In this paper, we developed a Windows XP version off-line programming system which can simulate a track vehicle model in 3D graphics space. The track vehicle was adopted as an objective model. The interface between users and the off-line program system in the Windows XP's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc. were utilized for 3D Graphics.

This experiment was conducted to study the effect of Nitrogen and Potassium treatment on growth, yield and content of mineral elements the results were summarized as follows; 1. Growth and Yields were more effective in N treatment with 8g per plant, were more effective in K treatment with 16 me per liter 2.Content of mineral elements in leaves were a lot of N and MG in N treatment, were a lot of P content in K treatment. 3. The content of mineral of Petiol, fruit and Xyleme sap. N and K were more contented in petiole, as the others were more contented in Xyleme sap. Ca was contented a little in fruit. 4. Absorption of water was increased in the N treatment with 8g per plants, in the K treatment with 16 me liter. The contents of chlorophyll was increased as the level of Nitrogen was increased in N treatment while, decreased on young leave in K treatment.
