This study sought to describe the relationships among physical environment, self-congruity, positive emotion, and revisit intentions in the coffeehouse setting. This study adopted second-order factor of physical environment in a structural equation model, imploying trend(fashion), cleanliness, reliability, spatial, convenience, and appropriacy as the second-order factors. The conceptual model in this study used responses from 338 college students who visited coffeehouse at least once in the past month. The proposed relationships were analyzed using SPSS 20.0 and AMOS 6.0. The results of data analysis indicated that the six secondorder factors of physical environment significantly affected coffeehouse visitor's self-congruity and positive emotion, and self-congruity as well as positive emotion significantly influenced revisit intentions. Further discussion and theoretical/practical implications of the findings along with directions for future studies are provided. In essence, the findings highlight significant role of coffeehouse's physical environment toward self-congruity and positive emotion in the formation of customer's revisit intentions in the coffeehouse context.

Purpose: This ethnography is aimed at describing the health care seeking behavior of elderly details in their socio-cultural context. The research question is 'under what conditions did elderly informants decide to use certain professional health care services and how do they make use of all the available resources?' Method: 10 sessions of fieldwork were conducted in the two agricultural villages between Sep. 1999 and Oct. 2002. The data for this paper came from participant observation with 14 informants. In the process of analysis I used proxemic and taxonomic techniques. Result: Informants decided to use a certain health care system according to their folk definition of illness. They prefer to use the health services where they felt more comfortable and free. They wished to be care from intuitive and holistic healers. Social network and having health resources was also important factor. Conclusion: We need more comprehensive research model to reach a plausible explanation. Combined qualitative-quantitative research is needed to get practical data to develop effective health care systems for the elderly.

In recent years, it is natural that the development and the maintenance of information systems are strongly dependent on outside service providers for economic reasons, especially in public sector. There has been an unexpected growth in the number of selection activities for outsourcing related works. At this time, selection of the contractor generally considers the proposals received based on the RFP(requested for proposal) and determines the ranking by experts committee. However, it is difficult even for expert giving a specific numeric score in weighting criteria or rating alternatives. In this context, an extended fuzzy TOPSIS method is applied for selection problem of IT proposals. A numerical illustration is also provided to demonstrate the applicability of the approach. This approach is very practical to help decision makers in assessing proposals during the selection phase under uncertainties.

The liquidity risk is defined as an additional risk in the market due to the timing and size of a trade. A recent work by Cetin et ai. (2003) proposes a rigorous mathematical model incorporating this liquidity risk into the arbitrage pricing theory. A practical problem arising in a real market application is an estimation problem of a liquidity cost. In this paper, we propose to estimate the liquidity cost function in the context of Cetin et al. (2003) using the constrained least square (LS) method, and illustrate it by analyzing the Kellogg company data.

Dyeings of the most widely used to the synthetic fibers, namely polyamide and polyester, have been carried out using acid dyes and disperse dyes. The above mentioned dye types, and indeed all dyes onto substrates, rely on the reaction properties between the substrates and dye molecules. In terms of fastness properties, however, especially to washings, the satisfactory levels are not present in the results from acid and disperse dyeings. Thus, vat dyeings leaves a feasibility and are an alternative way to overcome the problem. Although attempts and works have been reported in early years, with little if any commercial achievement and success. In this context, to meet increased demands towards a high level of wash fastness from consumers and retailers, an attempt using vat dyes has been carried out in this work.

Contract time determination for highway construction projects has never been easy despite considerable research efforts from academia as well as industry. High variations in crew production rates are considered one of the main barriers to accurate contract time determination. This paper presents a methodology for collecting field information on crew production rates which will help to enhance the accuracy of contract time determination for highway bridge construction. Based on a standard data collection tool developed, data on field crew production rates was collected from 14 on going projects in Texas, USA, over the past two years. The production rates based on the data collected were considered by industry practitioners to be more realistic and practical than those available to the current practices. As more data becomes available, key drivers influencing production rates could be identified and provide site personnel with a means to better plan and control production in a project specific context.

A numerical procedure is described for predicting the dynamic responses of combined systems of floating breakwaters and huge offshore structures supported by a large numer of the floating bodies in waves. The hydrodynamic interactins among tatal floating bodies are taken into account in their exact form within the context of linear potential theory. Wave control effects are discussed with both hydrodynamic interactions and hydrodynamic-structure interaction effects. The method presented is applicalbe to combined systems of floating breakwaters and huge structures for ocean space utilization for which a number of practical uses are seen in the future.

In this study, I investigate the critical evaluation elements at the architectural competition of the Rowhousing held nationwide in Germany. These evaluation elements, which can be regarded as the important design evaluation criteria, are selected by the design competition committee. Generally, in Germany the design competition committee consist of professors and famous architects who have theoretical and practical abilities with their own office. I classify and analyze the critical evaluation elements of 95 committee members, working on the selected 9 prize-winners in Germany from 1998 to 2002. I conclude that the critical evaluation elements, ordered by frequency are ; $\circled1$ context, $\circled2$ landscape & outside space, $\circled3$ arrangement of building, $\circled4$ circulation, $\circled5$ organization of plan, $\circled6$ economic aspects, $\circled7$ orientation of building, $\circled8$ parking, $\circled9$organization of form, $\circled10$ natural light. These design evaluation criteria for the Rowhousing in Germany also can apply to the korean case.

These evaluation elements, which can be regarded as the important design evaluation criteria, are selected by the design competition committee. Generally, in Germany the design competition committee consist of professors and famous architects who have theoretical and practical abilities with their own office. I classify and analyze the critical evaluation elements of seventy committee members, working on the selected nine prize-winners in Germany from 1997 to 2001. I conclude that the critical evaluation elements, ordered by frequency are : (1)circulation, (2)context, (3)function, (4)landscape & outside space, (5)organization of space, (6)arrangement of building, (7)form, arrangement of building, (7)form, (7)growth & change, (9)elevation design, (10)utilization of natural light. These design evaluation growth & change, (9)elevation design, (10)utilization of natural light. These design evaluation criteria for Hospital Architecture in Germany also can be applied to the evaluation methods of the korean Healthcare facility design.
