Best value in value engineering has relation to cost and performance. But a severe problem in VE study of a project is to reduce value due to loss of performance, caused by focusing on cost reduction. Also a lack of understanding performance concept, no trial VE workshop as well as cost saving-based policy have not satisfied customer needs. A efficient and practical methodology for accomplishing best value in construction projects is proposed. This study developed a more objective approach for performance measurement approach of mega projects and suggested a systematic process of performance quantitative analysis verifying value improvement. The proposed performance measurement method would be very useful for better communication and consensus between stakeholders and VE team especially through value engineering.

In general, thickness of the sublayers under track is designed based on concept of vertical soil reaction value or vertical stiffness. However, this design method cannot take consideration into soil-track interaction under repetitive load, traffic condition and velocity of the train. Furthermore, the reinforced roadbed soils experience complex behavior that cannot be explained by conventional stress-strain relation expressed as soil reaction value k. The reinforced roadbed soils also can produce cumulative permanent deformation under repetitive load caused by train. Therefore new design method for the sublayers under track must be developed that can consider both elastic modulus and permanent deformation. In this study, a new design concept, a rule-of-thumb, is proposed as the form of design monograph that is developed using elastic multi-layer and finite element programs by analyzing stress and deformation in the sublayers with changing the thickness and elastic modulus of the sublayers and also using data obtained from repetitive triaxial test. This new design concept can be applied to design of the reinforced roadbed before developing full version of design methodology that can consider MGT, axial load and the material properties of the layers. The new design monograph allows the user to design the thickness of the reinforced roadbed based on permanent deformation, elastic modulus and MGT.

The attempt of the contemporary society to overcome the environmental crisis is considered what the whole world is currently interested in. Since value of resources recycling has become emphasized even more, the field of design is, now, working hard to prove how much they are passionate about this eco-friendly design. Of all those activities that the field of design is involving in, a concept called 'upcycling' is receiving the greatest spotlight as a new trend. When it comes to upcycling, you should understand it as a both functional and aesthetic upgraded idea of conventional 'recycling' which would re-use waste resources. With this upcycling, you will have a chance to re-create an object of a new value, and it is a design concept which would consider environmental aspects but also social aspects. Since the year of 2000, the field of furniture design has been pursuing a new design trend which would intensively concern this upcycling concept. In the light of the present circumstances described on the above, this study conducts a case analysis on how upcycling of different materials is applied to furniture design since the year 2000. In doing so, the study improve understanding on furniture design as proposing new ways for you to look at the concerned design. Not only that, it also comes up with ideas and directions for new upcycling furniture design which could be demanded by the environmental industry.

Purpose - On the basis of discussing the network economy concept and the commentary of the marginal revenue decreasing of traditional economic theory, The concept of network economy has just been put forward in recent years. The reason why such a concept appears is that the information technology, marked by computer network, plays an increasingly important role in economic activities. Some people define network economy as an economic form based on network technology and human capital. this paper points out network economy existing the marginal revenue increasing and analyzes the reasons that influencing the marginal revenue increasing. Research design, data, methodology - The network economy has fundamentally changed the traditional economic laws. The economic basis of industrial society is the law of incremental marginal cost, which reflects the socialization of high cost in industrial society. Results - As the number of network members increases, the value of the network increases explosively, and the value increases attract more members to join, resulting in more returns. Conclusion - In conclusion, network economy has changed many aspects of traditional economy, resulting in decreasing marginal cost, decreasing transaction cost in and out of enterprise organizations, and making the effect of increasing scale compensation more prominent. This is of great significance to the information construction in China.

This survey investigated elementary school teachers' Astronomical Spatial Concept and their Attitudes about Astronomy for Effectively Teaching Strategy. This study surveyed 53 teachers in Ulsan. The data were statistically analyzed by SPSS WIN 18.0. The results of this study are as follows : First, Elementary school teachers' level of understanding of the concept of astronomical space, usually lower. In particular, the lower the level of understanding of the concept of spatial location. Second, Elementary teachers' attitudes about astronomy, astronomers generally appreciate the value of the information and guidance, but difficult for astronomers had recognized. Third, the concept of space and astronomy astronomical elementary teacher attitudes about sex and there was no significant difference according to the teaching career. Therefore, in order to develop effective teaching strategies for elementary teachers attitudes about astronomy and astronomical space concepts from their spatial position to increase the understanding of astronomy, often on the job training to strengthen the astronomers should eliminate the difficulties.

Streaming data is a sequence of data samples that are consistently generated over time. The data distribution or concept can change over time, and this change becomes a factor to reduce the performance of a classification model. Adaptive incremental learning can maintain the classification performance by updating the current classification model with the weight adjusted according to the degree of concept drift. However, selecting the proper weight value depending on the degree of concept drift is difficult. In this paper, we propose a dynamic ensemble method based on adaptive weight adjustment according to the degree of concept drift. Experimental results demonstrate that the proposed method shows higher performance than the other compared methods.

This study aims to identify the special features of high-concept funology observed in fashion products and expressional media by exploring funology in an era of high-concept, the emotional paradigm of the 21st century. High-concept funology in today's fashion can be explained as follows: First, 'virtual reality', which is often seen in fashion shows and fashion commercials, enhances consumer participation and involvement with blurred boundaries between the real world and the virtual world. With the expansion of various forms of real-time communication with consumers, positive images of the brand are being projected to the consumers. Second, 'form transformability', which is often found in fashion products, promotes customers' purchase desire as they are able to present themselves in a more versatile way in the fashion product that is changeable in various designs. Third, 'integration of different fields', which is easily found in various fashion goods, engages consumers in a mutual interaction under an entertaining setting with the product that is made to satisfy their needs attuned to their digital lifestyle. Fourth, 'interactive responsiveness', which is mainly recognized in fashion stores and commercials, is characterized by its interactive playfulness that encourages consumer participation through entertainment contents and promotes brand intimacy, eventually adding more value to its name.

As luxury goods market has expanded and has become more affordable, luxury consumption value has become more diversified. The purpose of this study is to classify visible characteristics of luxury consumption by the degree of logo clarity, and to explain this classification in relation to personal luxury consumption values. Also, the study utilized the concept of cultural capital, in addition to the concept of economic capital, in order to aid understanding of current new luxury consumption trend and give directions on brand signal strategies for luxury brands. In order to develop a survey that could measure an individual's cultural capital, focus group interviews, each composed of 5 women in their twenties and thirties, were conducted. Then, the survey was conducted on 230 females residing in Seoul who have purchased at least one product from a luxury brand within a year. The results suggest that luxury consumption can be explained by 'self-oriented value' and 'others-oriented value' as suggested in precedent studies. However, no significant difference was found between economic capital and these two luxury consumption values. However, the more cultural capital one possesses, the more one is likely to pursue 'self-oriented consumption value'. In studying the correlation between luxury consumption values and preference for brand signal clarity, respondents with 'self-oriented consumption value' has shown low preference towards highly visible brand logo when design and quality were equivalent. Also, respondents with 'other-oriented consumption value' has shown high preference towards highly visible brand logo.
