Today, brands are transforming into a strategic structure which emphasize brand image more so that the product itself, and the brand identify that factors in personal preference and taste assume important positions. In particular, space where brand identify is factored in is increasingly in importance these days, which means that it is no longer about selling products themselves, but selling brand image. Accordingly, it is necessary to approach in a strategic manner when it comes to the space that factor in brand value in terms of selling brand image. Accordingly, this research examines the relationship between brand identity and space components through the space in coffee shops where brand identity is applied, to identify how indoor expression trend is utilized.

The valuation of biodiversity is a fundamental step in conservation. The useful framework for analysing the economic value of biological resources is that of total economic value (TEV) and TEV comprises both use and non-use values, the former related to an actual use made of the resource, the latter to a willingness to pay for the resource independently of any use made of it. There are several valuation approacher in environmental economics literature. However, stated preference approach should be introduced for valuation of biodiversity because it can estimate non-use value as well as use value. Contingent Valuation and Conjoint Analysis are representative methods in stated preference and Conjoint Analysis can be more useful for valuation of biodiversity. Futhermore, the combination of ecology and economics to assess biodiversity leads to an integrated framework. Thus, interdisciplinary work is required, involving both economists and ecologists transferring elements or even theories and models from one discipline to another and transforming them for their specific, mutually consistent purpose.

As the advent of the Internet, most of the modern firms are now forced to use the internet as one of telecommunication tools for daily activities, Especially, as the decision units and/or makers in a firm become geographically dispersed due to the globalization trend, the need for integrating them effectively on the Internet is getting attention from researchers and practitioners much more than ever. In literature, this kind of need has been specially conspicuous in the need for coordinating production and marketing activities which are known as one of the typically conflicting with each other in terms of purposes. Lee and Lee(1999) has proposed an interesting coordination environment for production and marketing, named PROMISE. This paper is aimed at improving the coordination algorithm utilized in PROMISE and accordingly proposing a web-driven DSS for the purpose of transforming PROMISE into a web-based decision support platform for production and marketing coordination.

In this research, unsteady groundwater flow in unconfined and homogeneous three layer aquifers is studied theoretically and experimentally. Numerical solutions are obtained by Runge Kutta and Runge Kutta Gill method after transforming the governing nonlinear partial differential equations to nonlinear ordinary differential equations. Experimental apparatus includes a test section filled with fine, medium and coarse sands. Experimental results are compared with the numerical solutions and both experimental and numerical results correspond well with each other. This numerical approach may be also applied to the cases which have more aquifers.

Purpose: This study was to explore health experiences of the low-income elderly living alone reflected in Newman's Health as expanding consciousness theory. Method: The researcher used Newman's praxis methodology because it is good for showing the process of interaction between the researcher and the low-income elderly living alone. Results: The significant characteristics of early health experience during a participant's lifetime were demonstrated that blamed themselves, being burden of themselves hopeless of their lives. However, after a turning point in health experience. The health experience of most of the participants evolved as expanding consciousness. Conclusion: This study has provided support for Newman's theory of health. Most of the participants recognized meanings in their patterns and authentic caring relationships with the nurse as researcher, pattern recognition as a nursing practice was a meaningful transforming process in the participant-nurse partnership. This participatory approach expands the scope of sharing health experience with the elderly living alone and with caring community people.

The information revolution is sweeping through the global economy. Information technology is transforming the structure of competition. The successful implementation of information technology is dependent on the effectiveness of information systems planning. However, it is very difficult to select an appropriate methodology for information systems planning given an organization situation. A contingency model is proposed on the selection of an appropriate approach depending upon the organizational situation. Although the contingency framework is not yet theoretically proved, the approaches suggested here turned out to be of benefit to the cases of the two real world projects studied. These approaches attempt to combine Business Systems Planning of IBM and Critical Success Factors in two different manners to make planning process more efficient and effective.

Independent component analysis (ICA) is a statistical method for linearly transforming observed high-dimensional multivariate data into several statistically independent components. ICA has gained wide-spread attention in a variety of fields including spectrum application. We focus on the application of ICA for separating independent sources from a set of mixtures and estimating their fractions in a mixture. The proposed method of estimating fractions is based on the regression model subject to the non-negativity constraint on coefficients. Simulation experiments are performed to demonstrate the performance of the proposed approach.

In this paper, we propose a new algorithm, so called the Signal Decorrelation via Virtual Translation of Array (SDVTA) algorithm, for estimating the directions of arrival(DOA's) of narrowband coherent signals incident on a general array. An effective procedure is composed of transforming the steering matrix of the original array into that of the virtually translated sensor array and taking the average of the transformed covariance matrices in order to decorrelate the coherent signals. The advantage of this approach is in that 1) it can estimate the DOA's of m-1 coherent signals(M : the number of array sensors) since the effective aperture size is never reduced. 2) a geometry of array is unrestricted for solving the narrowband coherency problem. 3) the efficiency of signal decorrelation does not depend on the phase differences between coherent signals unlike the Coherent Signal Subspace Method (CSM). Simulation results are illustrated to demonstrate the superior performance of this new algorithm in comparison with the normal MUSIC and examine the comparative performance with the various choices of the optimal transformation matrix under coherent signal environments.

Owing to the nature of locality in mask layouts, it appears that most mask layout problems can be solved by transforming a part of the given mask layout into a better layout segment continuously toward a global suboptimal solution. This notion of local transformation addresses major weak points of existing mask layout processing systems, which lack both extensibility and unifiability. This paper attempts to elaborate upon developing a new rule-based mask layout transformation system wherein most of the mask layout problems can be solved under the unified framework of local mask layout transformation. The rule-based mask layout transformation system is applicable to various mask layout problems such as net extraction, mask layout compaction, mask layout editing, and design rule checking. The experimental results show that the rule-based expert system approach is an efficient means of solving those mask layout problems, and thus confronting major drawbacks of existing layout processing systems.

According to the dynamic changes in the business environment, the structural transformation of firms has had an observable trend. An increasingly large number of firms have been transforming into either project-based organizations or project expert groups. This study aims to investigate the antecedents required for the optimal level of empowerment with consideration of the project-based team environmental nature and job characteristic. Three factors are applied to measure the significant effects on psychological empowerment as the result variables. To determine the antecedents and consequent factors of psychological empowerment, employees' interviews and precedent studies are used. For the empirical study, four determinants of empowerment variables are modeled into a second-order reflective construct. This study finds that psychological empowerment significantly affects performance. Therefore, this study can serve as a guideline for development and operating methods for project success.
