In fashion history, the color "green" has been used from ancient to modern times constantly. Especially nowadays, the worth of green in fashion is becoming bigger than ever before to express the longing for pure nature. The purpose of this study is to define green's imageries in western costume history. For the basic about green, first of all, this study researched green of origin, effect and costumes in western history, then classified green's imageries. Green's imageries expressed in western costumes can be divided mainly into a 'nature imagery' and a 'religious divinity imagery'. Nature imagery was extended again into 'youth, devil, citizen and ecology image'. Youth image came from the luxurious feature of nature and it was extended again into 'innocent love, virgin and immaturity'. Religious divinity imagery has been represented in the ancient Egypt, Islam and Christian religion. In those cultures, green was considered as a sacred color of Osiris, Mahomet and Holy spirit.

In the analysis of the foreign cases on the use of Transit Signal Priority(TSP), the reduction in bus travel time ranged from 6 to $32\%$. This study demonstrates how TSP can be applied to Ulsan Metropolitan City. TSP techniques were used on the bus routes that run eastward for 4.07 kilometers along Munsoo-Ro, a major artery in the most congested part of the city. The simulation was performed on one hour of peak traffic time, using the two TSP strategies of Early Green and Extended Green. The use of the Early Green strategy resulted in an average decrease in travel time ranging from 18.1 to $25.8\%$ and an increase in average travel speed ranging from 30.9 to $40.1\%$. The Extended Green strategy resulted in an average decrease in travel time ranging from 18.1 to $30.3\%$ and an increase in an average travel speed of approximately $30.1\%$. This study demonstrates that TSP is effective in decreasing travel time and increasing travel speed of the bus system in Korea.

This paper presents an extended Twyman-Green interferometry that enables simultaneous and real-time measurement of 5-DOF motion errors of the translational moving stage. This method uses a null balancing technique in which two plane mirrors are used as target mirrors to generate an interferometric fringe utilizing the optical principles of Twyman-Green interferometry. Fringe is detected by 2D photodiode array for high-speed measurement. Errors are then independently suppressed by activation of piezoelectric actuators through real-time feedback control while the machine axis is moving. Experimental results demonstrate that a machine axis can be controlled with motion errors about 10 nm in linear displacement, 0.15 arcsec in angular displacement

The purposes of this studies were (1) to compare environmentally responses with green responses, (2) and departmentalized green responses, (3) and linked green responses to sustainability. First, I compared environmental responses with green responses. Environmental responses and green responses had different paradigm. So it is impossible to compare them same criteria. And there is no theory and method to prove which is better. I can't tell which one is better because they environmental responses and green responses. Second, I departmentalized green responses and compared the advantages and disadvantages of each departmentalized green responses. Third, linked green responses to sustainability. It is difficult to seek environmentally sustainable society without losing sustainable economic growth. Green responses and environmentally sustainable society seems to impractical. Environmentally sustainable society and sustainable economic growth seems to will never meet no matter how far extended. At the present speaking, sustainable economic growth and an environmentally sustainable society were incompatible.

This paper presents an efficient three-dimensional (3-D) modeling algorithm using the extended approximation to an electric field integral equation. Numerical evaluations of Green's tensor integral are performed in the spatial wavenumber domain. This approach makes it possible to reduce computing time, to handle smoothly varying conductivity model and to remove singularity problems encountered in the integration of Green's tensor at a source point. The responses obtained by 3-D modeling algorithm developed in this study are compared with those by the full integral equation for a thin-sheet EM scattering. The extensive analyses on the performance of modeling algorithm are made with the conductivity contrasts and source frequencies. These results show that the modeling algorithm are accurate up to the conductivity contrast of 1:16 and the frequency range of 100 Hz-100 kHz. The extended Born approximation, however, may produce inaccurate results for some source and model configurations in which the electric field is discontinuous across the conductivity boundary. We performed the modeling of a composite model of which conductivity varies continuously and this shows the modeling algorithm developed in this study is efficient for 3-D EM modeling. For a cross-hole source-receiver configuration a composite model of which conductivity varies continuously can be successfully simulated using this algorithm.

The integral equation method is a powerful tool for electromagnetic numerical modeling. But the difficulty of this technique is the size of their linear equations, which demands excessive memory and calculation time to invert. This limitation of the integral equation method becomes critical in inverse problem. To overcome this limitation, a lot of approximation and series methods, such as conventional Born, modifed Born and extended Born, were developed. But all the methods need volume integration of Green tensor, which is very time consuming. In electromagnetic theory, Green tensor rapidly decreases as the distance between source and field cell increases. Therefore, the source cell which are far away from the field cell does not make an effect on the electric field of the field cell. Consequently, by ignoring the effect of Green tensor due to far away source cells, computing time for electromagnetic numerical modeling can be reduced dramatically. Comparisons of this new method against a full integral equation, extended Born approximation and series code show that the method is accurate enough much less time consuming.

China has achieved remarkable economic growth through an extended period of rapid industrialization. However, adverse environmental issues have become more prevalent during this time of development. In particular, car exhaust emissions in the country have become one of the most substantial causes of environmental degradation in China. To combat these issues, the Chinese government is actively implementing green car policies to mitigate the negative environmental concerns. Likewise, Chinese consumers' interest in green cars has also increasing. Despite these changes in consumer perceptions, research on Chinese consumers' green consumption behavior is still in its infancy. Therefore, an empirical study was conducted to measure the relationship between zhongyong(中庸) values, new ecological paradigm(NEP), and green consumption behavior for 334 Chinese consumers. As a result, the study found that the three sub-dimensions of zhongyong(中庸) values(multi-dimensionality, flexibility and compatibility) and NEP had a significantly positive(+) effect on the purchase intention of green cars. It was also found that NEP positively mediates the effect of flexibility and harmony on purchase intention of green cars. This study is expected to provide academic outcomes on China, which is currently the world's fastest growing green car market, as well as providing practical strategic implications for establishing unique green marketing strategy for China.

Purpose: This paper examined the role of conditional value in the green automotive industry. The relationships of conditional value's four factors, consumers' attitudes and consumers' intention to purchase green cars were investigated. The conditional value was extended by examining the effect of fuel prices. Research design, data, and methodology: This study is quantitatively designed. All variables were measured using a 7-point Likert-scale; 425 questionnaires were collected from the respondents in Malaysia. SmartPLS was utilized to examine the proposed nine hypotheses. Result: The results demonstrate a positive relationship between attitude and intention toward green cars. Additionally, the results of the relationships were as follows: fuel prices was the most significant predictor of Malaysian consumers' attitudes and consumers' intention to purchase green cars, followed by environmental consequences and government policy. However, retail sales promotions did not show a significant effect on both consumers' attitudes and intentions. Conclusion: The study's findings suggest that the Malaysian government should implement an integrated package that includes a fuel pricing policy that restricts the purchase of non-green cars, as well as a set of financial incentives for purchasing green cars. Moreover, it is valuable to conduct public awareness campaigns about the negative consequences of current consumption patterns.

The objective of this research was an investigation of the important green spaces in Daegu and to present the basic frame of green network in Daegu. Present the condition of the significant green spaces is as follows: In the 3km radius of the city center, the isolation and discontinuation of the green spaces was extensive, caused by crowding of houses and funeral parlours. Consequently, the isolation relaxation which leads to the additional creation of the green spaces and a buffering plan were demanded. In the transfer area of a 3∼6km radius, which is located between the city center's congested area and the suburb green spaces, the significant green spaces had high connection and buffering characteristic, but in the northwest and the south, serious discontinuation appeared between the suburb green spaces and the city conte green spaces. In the 6∼9km radius, the suburb important green spaces accomplished the function which extended the back core green spaces to the city center area. But creation of buffering green spaces was necessary in part because of proximity to the resident area. The results suggest a connection between green spaces on the base of the distribution of the important green spaces, were as follows: In the 3km radius, irregular direction lines appeared while a schedule one direction line appeared in 3∼6km and 6∼9km radius. The discontinued parts of the green network were caused by industrial complexes, house crowding, and cultivation areas. Consequently, reservation and creation plans of green spaces in response to this were demanded. Through the additional creation of green spaces in the discontinued parts, the basic frame of green network in Daegu was the radiation annular form. And it was suitable to activate the parks and the general green spaces.
