In this paper, we present a performance analysis for an MPEG-4 video codec based on the on-chip network communication architecture. The existing on-chip buses of system-on-a-chip (SoC) have some limitation on data traffic bandwidth since a large number of silicon IPs share the bus. An on-chip network is introduced to solve the problem of on-chip buses, in which the concept of a computer network is applied to the communication architecture of SoC. We compared the performance of the MPEG-4 video codec based on the on-chip network and Advanced Micro-controller Bus Architecture (AMBA) on-chip bus. Experimental results show that the performance of the MPEG-4 video codec based on the on-chip network is improved over 50% compared to the design based on a multi-layer AMBA bus.

The propellers used for big ships have a large diameter and are very heavy. In order to apply a precise and safe work process to them, it is necessary to use an exclusive turning system. For this reason, various techniques are applied to produce them. However, workers' convenience and safety are not taken into consideration enough at production sites. Conventionally, these propellers are designed to be separated as their turning system is loaded and rotated by empty weight. Therefore, it is necessary to replace such a design. This study tries to find the weaknesses of the design and structure of a conventional propeller turning system for large ships, to verify structure integrity of a structure in structural analysis, and to devise a plan for designing a new type of turning system. In the basic concept design and structural analysis for the turning system used in the propeller finishing process for large ships, this study drew the following conclusions. It was possible to develop the work process of the turning system for the propeller finishing process used for large ships, to obtain the dimensions for exterior design through a basic design. Structural analysis was conducted to find the structure integrity of the turning system. As a result, in the rail installed to transfer a gantry, the maximum stress was about 45MPa, about 5.5 times lower than the yield strength 250MPa. Therefore, the turning system was judged to be safe structurally.

As essential element of designers, foundation studies program helps student deal with the individual expression of imagination and variety of correspondence for solving design problem through the understanding of 2-D, 3-D basic design elements, principals, structures. Liberal art and foundation studio courses provides embodiment and settlement of design principal through the foundation studies expand to experiences systematically and deeply. After the Industrialization, foundation studies have developed from Bauhaus in German, the courses have been progressing and systematizing with the demand of time in United States. Growth of Industrialization, expanded design areas departmentalized to various of fields, then the segmentation of foundation courses tend to important than basic design courses. The introduction of information era, the appearance of computer is placed as a tool of design development and added to applied basic courses. This study is intended to know how to change the leading foundation courses in United State due to the revitalization of industrialization and information through the research and analyse to foundation design education curriculums. As a result, most of design school in United States provide drawing, 2-D, 3-D, and 4-D courses included 3-D design element as a basic studies and provide to students introduction to fundamental principal of design concept and communication in both theoretical and applied form. Also though the history, literature, critic, research and survey courses provide students to organize fundamental of systematical logic and understanding design system.

The curriculum system and documentation for advanced general education, MSC (Mathematics, Basic Science, Computer Science), and engineering-design courses have been developed to improve the education of advanced undergraduate students in engineering and technology at Chosun University. In this paper, to obtain improved quality of engineering courses, we systemized the education of engineering and technology, which could be designed as the education satisfying students and provide awards for high-quality performance, through efficient management of education courses and establishment of basic and professional courses. In addition, by applying evaluation to the engineering courses and using the model of continuous quality improvement, we could achieve a high-quality education system for the engineering and technology courses.

Basic design of a solar driven absorption cooling machine(SDACM) with a cooling capacity of 5 USRT was carried out. The SDACM is a single effect cycle driven by low temperature hot water from solar collectors. The SDACM design data were calculated by the steady state simulation program which was developed in this study The variation of COP and cooling capacity of the SDACM were investigated at different off-design conditions. Both the cooling capacity and the system COP were improved with decreasing cooling water temperature. If hot water temperature was increased, the cooling capacity was improved but the system COP was found to be decreased. The decrease of the system COP were basically caused by increased thermal loads in the system components.

This study intended to put information regarding space composition and functional relationship together and analyze them, and finally offers some suggestions. For the field survey, built questionnaire and drawings analysis were used in this study. Architectural programming offers basic information for design : putting field survey factors together and analysing them. It interacts with each part of design as well. In the initial stage of architectural design, the quality of information is very decisive in the quality of design. In this sense, analysing basic information such as floor space compositive system is required to rationalizing space and functional programing in the elementary school design.

Most production scheduling system in the ERP is based on the MRP. The MRP does not adapt to the change of the product design and the production schedule. It is important to keep due date in make-to-order production small and medium company. But it hard to keep due date on the MRP. The DBR Scheduling system of the TOC is excellent for adapting to production system change and suitable to make-to-order production small and medium compan. In this thesis, we make a system design using the Together(UML tool) and develope a production scheduling system using Microsoft Visual Basic.Net.

The industrial environment for shipbuilding in 21st century requires increase in few type of ships and marine structures, international cooperation and globalization, while virtual enterprise environment is rapidly establishing. On the other hand, more and more efforts will be spent on internet based distributed and collaborative environment rather than being spent on unit level automations such as CAD, CAM and CAE, and the link between them. Recent internet technology and information technology in heterogeneous environment are being applied in shipbuilding industry as well as in other industries. While these technology are rapidly adopted in major shipyards, many small and medium-sized shipyards does not have enough resources to introduce system designed for large enterprise. In this paper, a prototype of Internet technology based basic planning system is implemented for the small and medium sized shipyards based on the internet technology and concurrent engineering concept. First, the system is designed from the user requirements. Then standardized development environment and tools are selected. These tools are used for defining and evaluating core application technologies for the system development. This can guarantee the survival of small and medium-sized shipyards in 21st century industrial environment.
