Embedded system is applied in various fields and must equip system to respond market's requirement which is changing fast. Products that do not equip such fast construction system will have become sterilization. Construction system for Time-To-Market is reusability system or framework that have reused existent product and produce new product. Because embedded system is being based on hardware, amendment is not available easily, but can change system softly using segment of software. Therefore, in this paper, suggest meta-model of reusability framework that can change embedded software. Meta model of this paper suggests dynamic meta-model to design functional flow of reusability framework.

As remodeling market is growing and peoples' concern on health and well-being is getting high, there is a need to apply environmentally friendly approach to remodeling an interior space. Therefore, the purpose of this study is to provide basic information on environmentally friendly remodeling process focused on the implementation of interior construction process. The method of this study was two-folds. First, previous researches were reviewed to drive general remodeling process, and then content of implementation of environmentally friendly remodeling process were added. Second, semi-structured interview was conducted to eight experts in interior design who were members of KOSID. The results of this study are as follows; (1) Applying environmentally friendly method to remodeling will be essential. Therefore, it is necessary to develop various types of environmentally friendly finish materials and methods and continuing attention should be paid. (2) For broad implementing an environmentally friendly application on remodeling, builders, interior designers, manufacturers, and clients should change their consciousness through education and publicity, (3) The results showed that using environmentally friendly materials was the most primary concern for the designers. However, there is a lack of information about contamination derived from materials when manufacturing and constructing and even wastes. Thus designers should be aware of using environmentally friendly verified materials regarding materials itself and its manufacturing process.

The traditional image of hydraulic excavator started to change in two ways since 1990. First, post-heavy equipment's visual image was new waves to traditional image of heavy, strong, and wild. They are the negative aspect that excavators have. Another movement of getting rid of its negative image can be found in late-heavy equipment, which was intended to adapt traditional and positive, but off negative images. In 1990s, the design trend is moving from warm/hard to warm/soft, and KOBELCO can be exceptional example that went even further, gone up to cool-soft image. KOBELCO specially aimed 'post- excavator image' strategy, which has been successful. Image of cabin as a human space changed little bit further than outside image. Each company tried to differentiate the design of cabin focusing on its safety. Following paragraphs show specific trend of image change in form, colour, texture, and the composition. Major visual image change in form tries to follow the image of cars and home appliances which are showing the movement from tough and hard image to soft one. Structural change on local image shows the movement from angular edge to edgeless and the movement of cabin's pillar C placed to back of the equipment with gentle inclination. All of these movements are the result of effort to improve traditional excavator's negative image, that top structure is assembled separately, to positive ones. Today's tendency about its color becomes important to apply two different colour styles. Each style has brightness and tone comparison. As an enormous power convey system, it was in common that its brightness comparison was useful because of the alarm of its damage possibility. However, as its colour control and its design have been emphasized gradually, the tone comparison takes a part in an important role, too. As an example, there is an occasion that these comparisons are compromised simultaneously. In the respect of its image creation, its texture treatments make the tendency of being the same as passenger cars. It is caused from its development of the manufacture techniques of from the fabrication method in small business to the press method in big firm. Further, it is also because of its improvement of painting & coating skills. It may prohibit the reflection effect from solar rays. In the point of view of its visual images, it is recognized the prominent tendency that its composition has been gradually decreased. Lots of windows and the frames tends dark-colour as a whole. It is more preferred to have one colour image, but except KOBELCO and HITACHI. As well, there is another high-tendency to improve its standard treatments, especially for its corner and texture treatments.

In 2004, KTX operated in Korea on the 5th in the world. But there are various factor on planed schedule delay of Big National Construction Project like Seoul-Busan High Speed Rail Project(Seoul-Busan HSR). For example, Often change of government policy, project management control problem of design and construction, conflict of interested party like environmental organization/resident are the main delay factors. The suggestions for improvement of the construction schedule through the Seoul-Busan HSR will help to make a new leap forward in rail construction.

The construction project manager must clearly carry out the activities of each construction stage specified in the 'Task Description'. In this study, 'design change' and 'completion process' were classified as core tasks in consideration of the frequency and importance of tasks. And, by analyzing the actual construction project, the task contents for the core work were standardized. This laid the foundation for the ordering office, construction project management technicians, and builders to clearly understand the business areas of construction project management and fulfill their responsibilities for their respective tasks.

Unlike a completed building, a building under construction may be at risk in terms of safety if a load exceeds the value considered in the design stage owing to various factors, such as a load action different from that in the design stage and insufficient concrete strength. In addition, if an earthquake occurs in a building under construction, greater damage may occur. Therefore, this study studied example models with various sizes of 5, 15, 25, and 60 floors for typical building types and analyzed the effects of seismic load on buildings under construction using construction-stage models according to frame completeness. Because the construction period of the building is much shorter than the period of use after completion, applying same earthquake loads as the design stage to buildings under construction may be excessive. Therefore, earthquakes with a return period of 50 to 2,400 years were applied to the construction stage model to review the seismic loads and analyze the structural performances of the members. Thus, we reviewed whether a load exceeding that of the design stage was applied and the return period level of the earthquake that could ensure structural safety. In addition, assuming the construction period of each example model, the earthquake return period according to the construction period was selected, and the design appropriateness with the selected return period was checked.

Today, offshore design field is concerned with system integration such as CIM(Computer Integrated Manufacturing), PDMS(Product Data Management System) and EDMS(Engineering Data Management System) in order to cope with the change of engineering specification as owner's requirements during construction stage of the project. This paper deals with the case study that describes about the efficient interface between material control system and 3D CAD system to support the design process in offshore industry using design rules involved the designer's knowledge. In this paper, we constructed an information system, called knowledge-based CAD interface systems, which is composed material code management system and 3D specification generator which automatically creates 3D catalogue anti specification by linking the material code, called short code, and the specification components of the 3D CAD system. As a result of the construction, it is possible to maintain consistency of the design process, and through reduction of the design processing time and improvement of the design process, competitiveness is improved.

The interior noise reduction of construction equipment is concerned for improving the driver comfort in this study. From the baseline test, the exhaust noise gives a big contribution to the interior noise of construction equipment. And the detail noise contribution analysis of the exhaust system, the tail pipe, which is for ventilation an engine room hot air to outside, amplify the exhaust noise around operating engine RPM associated with tail pipe structural and cavity resonances. To remove the noise amplifying effects, the tail pipe has to be shorted its length. Even the noise can be attenuated the ventilation flux when using the redesigned tail pipe is reduced than the original one. Thus, a shape change of the tail pipe is additionally needed for increasing the ventilation flux and attenuating the exhaust noise using CFD technique. The CFD results of the tail pipe give a meaning full information what obstructs the ventilation flex in the current design and how changes the tail pipe.
