According to the change of industry structure, design is the key element to accelerate enhance the value of railway industry as they core competence factors for productive and superiority its level. It is important utilizing materials to embody new train aesthetics and build high technologies. Consequently, apply properties of composite with design formative attribute also functional usability and technology system.

The total estimated socioeconomic logistics cost in transportation sector, including traffic congestion, household travel expenses, national macroeconomic logistics and traffic accident related cost, amount to approximately 240 trillion won a year in 2009. The amount is in increasing trend every year due to the inefficient infrastructure system in urban city roads and in intercity highways. The Government adopts the 4th National Spatial Planning (Revised) which is in progress in order to build a new physical environment ensuring people's welfare by providing the efficient and sustainable transportation networking system.

Companies had to be more intelligent in order to survive in the rapidly changing environments. We need to make a decision to build the Information System to support their decision making. But, how can we know the new system would be better than the old system in making us intelligent? The answer is we can do it with the concept of Intelligence Density. In this study, Intelligence Density concept will be introduced, and the way how it can be applied to the information system will be presented. I think Intelligence Density should be studiedmoretohelpmanagersmakerightdecisions.

Manufacturing industry is on the verge of a major paradigm shift. This shift will take us away from mass production, way beyond lean manufacturing into a world of new intelligent and agile manufacturing. We spent most of our time during the 1980s copying the Japanese. This paper studys reengineering methodologies to build up low-cost manufacturing systems efficiently in Korean companies

This study aims to investigate the characteristics of Lee Kyo-Won's landscape architecture and add to the literature in this field. Also, the current status of and issues in landscape design will be dealt with through the lens of the individual landscape architect's worts. By adopting a critical analysis, this study will look closely into the background of his career and ideas regarding landscape design. The inherent nature of his coherent style in landscape design will be listed as follows: total design, design-build systems, experimentation with new kinds of plants and materials, and the pursuit of minimalism. His design domain covers various elements such as paving, street lamps, and clock towers, among others. He was often involved in managing outdoor sculpture and he also provided the total packaging of the design-build systems for most of his landscape projects. These are the main reasons why his landscape works can maintain their high end quality; through his craftsmanship, a fine quality of detail was achieved in his landscape design. This tell us the possible options that can be adopted such as landscape architectural design management or landscape architectural turn-key systems, which differ from the prevailing dual system between design and construction. However, his own particular system can not be replicated in ordinary situations because contemporary practices require us to coordinate the various stakeholders concerned in the decision-making process of the design. In general, it is fair to say that we can give him the credit for enhancing the status of landscape design as an independent, specialized field.

PPPs(Public Private Partnerships) in Korea was introduced in 1990s, which mainly used for providing transportation facilities such as railroad and high-way. Since 2005, a service delivery type PPPs, in other words BTL(Build Transfer Lease) has been implemented, which focused on social infra-structure including school, military housing, and sewage facilities. According to previous literature, efficient risk evaluation and management is the key factor for successful PPPs in the UK and Australia. However, Korea doesn't have proper risk evaluation system for PPP type project. In this paper, we explore and analyze risk evaluation system of PPPs in Korea and other countries. Also, we apply empirical methodology used in the UK to a BTL project and set up a new PSC(Public Sector Comparator) with risk evaluation.

RP techniques have their unique characteristics according to the working principles : star-stepped surface of parts due to layer-by-layer stacking low build speed caused by line-by-line solidification to fish one layer and post processing to improve surface finish etc The objective of this study is to propose a new RP technique Variable Deposition Mnanufacturing (VDM) which can make up for the disadvantages of the existing RP techniques and to develop an apparatus to implement the technique. The proposed process can greatly reduce the build time and improve the surface finish of parts generated. Experiments are carried out to obtain the range of temperature of molten material to maintain its fluidity and to investigate the effect of gas cooling on the preservation of the slopes. Some simple shapes such as a line-shape an S-shape and a circle-shape are fabricated from Ethylene Vinyl Acetatecopolymer(EVA) In order to examine the applicability of VDM to more general shapes a tensile specimen and a yo-yo shape were manufactured by the proposed RP method using EVA material as a trial approach. The current basic study shows a high potential of practical use of the proposed VDM process to prototyping of a general three-dimensional shape.

PFI(Private Finance Initiative) Project is carried to expand infrastructure effectively through participation of private investment. From the year 2005, the range is expanded not only industrial infrastructure such as made road, harbors and so on but living infrastructure such as school facilities, environmental facilities. For this reason BTL(Build-Transfer-Lease) system is mainly used in new private finance initiative project but in existing private finance initiative project BTO(Build-Transfer-Operate) system was used. BTL system is operated to judge fitness of private investment and classified into quantitative VFM(Value for Money) and qualitative VFM. In this research the estimation item of qualitative VFM which is hard to deduce the effect is created and after surveying of questionnaire in target of experts, relative importance and weight is established with AHP(Analytic Hierarchy Process). By estimating efficiency and benefit of quantitative VFM and qualitative VFM aspect effectively it is expected to support a rational making decision for operating BTL.

In 2005, the revision of the Private Investment Law made the private investment objectives to extend a new area, such as institute and well-fare, military facilities by BTL(Build-Transfer-Lease). This revison will cause budget extension from 1.3 trillion to 1.6 trillion in military facilities BTL project Therefore, it is necessary to analyze the general problem of BTL and its cases. And then to be successful project, the problems must be improved. This study was focused on the improvement of regulations and analyzed the general problem from previous studies and the military projects. And then it conducted survey to soldiers for severity and performance. Finally it suggested the improvement of regulations of military facilities in BTL scheme from FGI.
