이 연구는 자유주의적 전통에 서있는 롤즈의 정의론을 환경정의의 개념화를 위해 응용함에 있어 어떤 의의와 한계를 가지고 있는가를 검토해 보고자 한다. 이를 위해, 이 연구는 우선 롤즈의 자유주의적 정의론을 개관하고, 보다 구체적으로 롤즈의 정의이론이 환경자원의 정의로운 분배의 개념화에 어떻게 적용될 수 있는가를 고찰한 후, 롤즈적 정의론을 동물 및 자연의 여타 구성원들로 확장할 경우 발생할 수 있는 문제점들을 논의하고자 한다. 이러한 논의의 결과로 다음과 같은 점들이 주장된다. 롤즈의 이론에서 자연자원의 상태는 정의의 객관적 조건으로 서술되고 있지만, 정의로운 생산과 분배의 실제 요소로서 이해되어야 할 것이다. 그의 정의론은 자원의 정의로운 분배를 위해 중요한 의미를 가지지만, 분배의 결과에 대한 실제적 정의를 보장하는 것은 아니다. 그의 이론을 동물 및 자연의 여타 구성원들로 확장하는 것은 거의 불가능한 것처럼 보인다. 왜냐하면 그의 이론이 근거하고 있는 자유주의, 나아가 서구의 과학적 전통은 인간과 자연간의 존재론적 이원론에 바탕을 두고 있으며, 따라서 자연의 내재적 가치를 인지할 수 없기 때문이다.

The aim of this study is to examine the linkage between environmental theory and physical development such as housing estate developments. Firstly, this paper examines environmentalism to see varying approaches in the resolution of environmental problems. Here, Technocentrism, Econcentrism and Ecosocialism was seen as dominant theoretical approaches. Secondly, an international case study on ecological housing development was conducted. Four German, Australian, Japan and Korean examples were taken as cases which revealed a wide spectrum of development tendencies. An analytical framework of building methods evaluated by the environmental theories was established. And by evaluating the cases with this framework, we were able to find out the overall environmental character of each housing developments. The hypothesis of this paper is that these differences can be explained through the differences that exist in society which the theoretical represents. The research revealed strong linkage with social tendencies.

This work investigates a new type of quasi-3D hyperbolic shear deformation theory is proposed in this study to discuss the statics and free vibration of functionally graded porous plates resting on elastic foundations. Material properties of porous FG plate are defined by rule of the mixture with an additional term of porosity in the through-thickness direction. By including indeterminate integral variables, the number of unknowns and governing equations of the present theory is reduced, and therefore, it is easy to use. The present approach to plate theory takes into account both transverse shear and normal deformations and satisfies the boundary conditions of zero tensile stress on the plate surfaces. The equations of motion are derived from the Hamilton principle. Analytical solutions are obtained for a simply supported plate. Contrary to any other theory, the number of unknown functions involved in the displacement field is only five, as compared to six or more in the case of other shear and normal deformation theories. A comparison with the corresponding results is made to verify the accuracy and efficiency of the present theory. The influences of the porosity parameter, power-law index, aspect ratio, thickness ratio and the foundation parameters on bending and vibration of porous FG plate.

This work applies a four-known quasi-3D shear deformation theory to investigate the bending behavior of a functionally graded plate resting on a viscoelastic foundation and subjected to hygro-thermo-mechanical loading. The theory utilizes a hyperbolic shape function to predict the transverse shear stress, and the transverse stretching effect of the plate is considered. The principle of virtual displacement is applied to obtain the governing differential equations, and the Navier method, which comprises an exponential term, is used to obtain the solution. Novel to the current study, the impact of the viscoelastic foundation model, which includes a time-dependent viscosity parameter in addition to Winkler's and Pasternak parameters, is carefully investigated. Numerical examples are presented to validate the theory. A parametric study is conducted to study the effect of the damping coefficient, the linear and nonlinear loadings, the power-law index, and the plate width-tothickness ratio on the plate bending response. The results show that the presence of the viscoelastic foundation causes an 18% decrease in the plate deflection and about a 10% increase in transverse shear stresses under both linear and nonlinear loading conditions. Additionally, nonlinear loading causes a one-and-a-half times increase in horizontal stresses and a nearly two-times increase in normal transverse stresses compared to linear loading. Based on the article's findings, it can be concluded that the viscosity effect plays a significant role in the bending response of plates in hygrothermal environments. Hence it shall be considered in the design.

The $21^{st}$ century is a new century of environmental protection. Environmental protection is one of the most important subject matters yet to come. Moreover, as the public pays more attention to environmental problems, enterprises should increase their investment in environmental management. Therefore, determining the investment level for environmental management and allocating the investment to associated environmental management activities has become a major task. The principal and agent theory and sales response functions are used for analysis in this research. The allocation of capital investment in environmental management is found to have significant impact on the aggregate sales response, aggregate profit and investment level. Therefore, in preparing the budget for environmental management, enterprises should focus on investment allocation decisions, determine the investment level and allocation method using integrated means, and apply submarket data in the allocation decision-making process. In other words, in setting the investment level, executive management should take managers' willingness into consideration. In allocating capital investment, managers should identify the optimal allocation method based on submarket characteristics.

Lighting poles and antenna masts are typically high, slender and light structures. Moreover, they are often characterized by distributed eccentricities that make very complex their shape. Experience teaches that this structural type frequently suffers severe damage and even collapses due to wind actions. To understand and interpret the aerodynamic and aeroelastic behavior of lighting poles and antenna masts, this paper presents the results of static and aeroelastic wind tunnel tests carried out on a complex prismatic element representing a segment of the shaft of such structures. Static tests are aimed at determining the aerodynamic coefficients and the Strouhal number of the test element cross-section; the former are used to evaluate the critical conditions for galloping occurrence based on quasi-steady theory; the latter provides the critical conditions for vortex-induced vibrations. Aeroelastic tests are aimed at reproducing the real behavior of the test element and at verifying the validity and reliability of quasi-steady theory. The galloping hysteresis phenomenon is identified through aeroelastic experiments conducted on increasing and decreasing the mean wind velocity.

This paper attempts to measure the environmental value of the Nakdong-river estuary, which is ecologically important but confronted with the threat of development. Especially, in order to elicit the environmental values of its four attributes, contingent valuation method(CVM) based on multi-attribute utility theory is applied and the CVM survey was rigorously designed to comply with the guidelines for best-practiced CVM studies. We surveyed a randomly selected sample of 400 and 350 households in Busan and six large cities(Seoul, Incheon, Daegu, Daejeon, Gwangju, and Ulsan), respectively and asked respondents questions in person-to-person interviews about how they would willing to pay for the estuary conservation and management program. Respondents overall accepted the contingent market and were willing to contribute a significant amount(2,457 won in Busan and 3,560 won in six large cities), on average, per household per year, which implies that there exists a large difference between the two. The aggregate values of the Nakdong-river estuary in Busan and six large cities amount to 2.92 and 22.32 billion won, respectively, per year. In addition, expanding the values to Korea produces 51.34 billion won per year. The quantitative values can be utilized in planning and decision-making about development versus conservation of the estuary.

This study analyzes the role of market actors in the energy transition process and the interaction between them and ordinary citizens, primarily focusing on the mini-PV project in Seoul. The study also proposes measures to harness market actors' activities and successfully implement the distribution of mini-PV systems in Seoul. In this study, practice theory is used as a theoretical resource to analyze the interaction between market actors and civil society actors and to help understand how market actors influence the decisions of regular citizens in installing mini-PV at their properties. After conducting surveys and hosting in-depth interviews with ordinary citizens and market actors, it was found that to further promote the role of market actors, the Seoul Metropolitan Government should actively support and monitor the public relations activities of market actors, while concurrently managing selected companies and establishing relevant administrative systems for continued effective use post-installation of mini-PV systems. In future studies of the energy transition process, market actors should also be recognized as key players, along with government and civil society actors, and their roles should be studied in a balanced way.

This study examines factors determining contemporary Chinese households' food away from home (FAFH) expenditures using Becker's household production theory. Data came from the 2000 urban household survey in Guangdong Province, collected by National Bureau of Statistics (NBS) of China. It was revealed that the contemporary urban Chinese wives also substitute their household work by time-saving product, FAFH, as Becker's household production theory postulated. This suggests the important role of time-value (opportunity cost) in determining household FAFH expenditure across the cultures.
