  • Consumer perception of the meaning of 'green' and 'green products' as well as how they use green claims (including terms, certifications, and marks) should be examined to help consumers pursue green behavior in everyday life. This study investigates what type of green claims prevail in the Korean consumer market and how consumers perceive the meaning of 'green' and green claims. For these purposes, media analysis, in-context research (shop visit) and a survey were conducted to collect green claims (including green terms and certified/noncertified green marks). Green claims in the consumer market were first summarized and analyzed; subsequently, the most frequently used 7 green marks and 15 green terms were selected to construct a consumer survey questionnaire on consumer perceptions of green claims. An online survey was performed via Embrain and the survey respondents consisted of 500 adult consumers over the age of 20. The field research results showed frequent green claims in the Korean consumer market. However, certified (and hence trustworthy green product information labels) were uncommon in the market. The only green claim widely known and used by consumers was the energy consumption efficiency label. Consumers were interested in the green information label not because it affected their utility cost nor because it was important for environment protection.

  • Revisited in this paper are Green's functions for unit concentrated forces in an infinite orthotropic Kirchhoff plate. Instead of obtaining Green's functions expressed in explicit forms in terms of Barnett-Lothe tensors and their associated tensors in cylindrical or dual coordinates systems, presented here are Green's functions expressed in two quasi-harmonic functions in a Cartesian coordinates system. These functions could be applied to thin plate problems regardless of whether the plate is homogeneous or inhomogeneous in the thickness direction. With a composite variable defined as $z=x_1+ipx_2$ which is adopted under the necessity of expressing the Green's functions in terms of two quasi-harmonic functions in a Cartesian coordinates system Stroh-like formalism for orthotropic Kirchhoffplates is evolved. Using some identities of logarithmic and arctangent functions given in this paper, the Green's functions are presented in terms of two quasi-harmonic functions. These forms of Green's functions are favorable to obtain the Newtonian potentials associated with defect problems. Thus, the defects in the orthotropic plate may be easily analyzed by way of the Green's function method.

  • As environmental pollution and resource exhaustion have been considered as social issues, interest in green content industries which lead low-carbon green growth is increasing. In various areas, green content products and programs have been presented. Of them, kid theme parks are designed to recognize fun and advantages eco-friendly consumption with green contents has and lead children to recognize the problems of environmental pollution and the importance of environment. This study aims to analyse kid theme parks using green contents and characteristics of their space representation. The analysis frame was made through theoretical examination for bibliographical data and a direct interview in terms of factors of green contents. For the analysis frame, visitors were directly interviewed from June to July, 2012. Cases of introduction were analysed to identify realization and characteristics of green contents. As a result of the analysis, it was discovered that kid theme parks using green contents pursued green stories, but they did not consider environment seriously in terms of content materials and methods of realization. To develop successful kid theme parks using green contents, multi-dimensional research is needed in various aspects and various contents such as media should be introduced. The parks should provide fun space for children and propagate green ideas. Its success can lead in green entertainment. The study will be helpful for design of future kid theme parks.

  • Green's functions are obtained in exact closed-forms for the elastic fields in bi-material elastic solids with slipping interface and differing transversely isotropic properties induced by concentrated point and ring force vectors. For the concentrated point force vector, the Green functions are expressed in terms of elementary harmonic functions. For the concentrated ring force vector, the Green functions are expressed in terms of the complete elliptic integral. Numerical results are presented to illustrate the effect of anisotropic bi-material properties on the transmission of normal contact stress and the discontinuity of lateral displacements at the slipping interface. The closed-form Green's functions are systematically presented in matrix forms which can be easily implemented in numerical schemes such as boundary element methods to solve elastic problems in computational mechanics.

  • This study discusses the environmental awareness and the second-hand clothing usage of those consumers who actively purchase used clothing through a clothing swap at a used clothing market. The study used the questionnaire method, weか the subjects being those with experience of buying second-hand clothing. The findings were as follows. 1. The group of higher environmental awareness differed from the group with low environmental awareness in terms of donating or swapping clothing at a green store or in terms of discontinuing the wearing of used clothing bought from a green store. 2. The higher environmental awareness group valued fashion, status symbols and the alignment with others while the group with low environmental awareness valued comfort and economy more than those with the higher environmental awareness. 3. It was discovered that environmental awareness, education and income levels were interrelated.

  • As a green construction is a world-wide hot issue, Korean government is also putting forth a multilateral effort into reducing energy usage with setting aggressive goal under green growth policy. It is essential to analyse cost raised from designing and building green construction and benefit derived from the built facility for the sustainable green construction. However, compared to advanced countries in terms of green construction, there is lack of data and a systematic way for data collection and analysis in Korea. Without analyzing the cost-benefit of green construction, investors will hesitate to put his/her money into green construction and we can not expect its growth in construction industry. In this paper, cost of green construction was defined and categorized. Through case studies and various reports on cost-benefit analysis in advanced green construction countries, problems in terms of data collection and analysis in domestic green construction sector and improvement ways were suggested. The results of this study will contribute in classification of cost and benefit of green construction, data collection in systematic way, and increasing the feasibility of green construction via appropriate analysis on cost-benefit of green construction.

  • Green roof in Korea has been recognized as part of landscape area and local governments enacted municipal ordinance for supporting green roof thereby assisting part of expenses spent for green roof within a range of budget for buildings which are eligible for the green roof support of existing buildings. However, it is necessary to enforce a regulation of mandatory green roof for new buildings in order to expand green roof application and provide a variety of assistances such as subsidy payment, tax relief, and mitigation of floor area ratio-related regulation as done in other advanced nations. In particular, LEED(Leadership in Environmental and Energy Design) in the USA applies additional point directly for green roof in terms of the reduction in heat island effects. For example, the following items are beneficial to have additional points: habitat preservation or restoration, external space, rainwater management, reduction in outdoor water usage, minimum energy performance, and optimum energy performance. In addition, the BREEAM(Building Research Establishment Environmental Assessment Method) in the UK specifies green roof as one of assessment items to be complied in terms of diversity of species. As such, LEED and BREEAM reflect direct and indirect effects of green roof on assessment criteria, which suggest a direction to green building certification criteria in Korea where only additional points are given for green roof according to soil depth.

  • This study aims to analyze the qualitative and quantitative effects of environmental policies in terms of green space management using logistic regression model(LRM). Landsat satellite imageries in 1985, 1992, 2000, 2008, and 2015 are classified using a hybrid-classification method. Based on these classified maps, logistic regression model having a deforestation tendency of the past is built. Binary green space change map is used for the dependent variable and four explanatory variables are used: distance from green space, distance from settlements, elevation, and slope. The green space map of 2008 and 2015 is predicted using the constructed model. The conservation effect of Ulsan's environmental policies is quantified through the numerical comparison of green area between the predicted and real data. Time-series analysis of green space showed that restoration and destruction of green space are highly related to human activities rather than natural land transition. The effect of green space management policy was spatially-explicit and brought a significant increase in green space. Furthermore, as a result of quantitative analysis, Ulsan's environmental policy had effects of conserving and restoring 111.75㎢ and 175.45㎢ respectively for the periods of eight and fifteen years. Among four variables, slope was the most determinant factor that accounts for the destruction of green space in the city. This study presents logistic regression model as a way of evaluating the effect of environmental policies that have been practiced in the city. It has its significance in that it allows us a comprehensive understanding of the effect by considering every direct and indirect effect from other domains, such as air and water, on green space. We conclude discussing practicability of implementing environmental policy in terms of green space management with the focus on a non-statutory plan.

  • A Green's function approach is adopted for analyzing the thermoelastic deformation and stress analysis of a plate made of functionally graded materials (FGMs). The solution to the 3-dimensional steady temperature is obtained by using the laminate theory. The fundamental equations for thermoelastic problems are derived in terms of out-plane deformation and in-plane force, separately. The thermoelastic deformation and the stress distributions due to the bending and in-plane forces are analyzed by using a Green’Às function based on the Galerkin method. The eigenfunctions of the Galerkin Green's function for the thermoelastic deformation and the stress distributions are approximated in terms of a series of admissible functions that satisfy the homogeneous boundary conditions of the rectangular plate. Numerical examples are carried out and effects of material properties on thermoelastic behaviors are discussed.
