The purposes of this study were to segment department store customers based on patronage orientations of service facilities in a department store and to develop a profile of each segment using store visit behaviors, clothing purchase behaviors and demographics. A total of 453 responses collected from an on-site questionnaire survey to female department store customers was analyzed. Cluster analysis on patronage orientations of department store service facilities identified four groups including: Active patrons(27.3%); Comparison patrons(27.6%); Convenience seekers(27.3%); and Minimum patrons(17.8%). ANOVA and $\chi$$^2$ analyses revealed significant differences among the four groups on store visit behaviors(the extent of store visits and the extent of service facility visits), clothing purchase behaviors(6 store choice criteria and the extent of clothing purchase), and 5 demographic characteristics. The study developed a profile of each segment and provided marketing implications.

The research presented in this paper deals with the seismic protection of existing frame structures by means of passive energy dissipation. A displacement-based procedure to design dissipative bracings for the seismic protection of frame structures is proposed and some applications are discussed. The procedure is based on the displacement based design using the capacity spectrum method, no dynamic non linear analyses are needed. Two performance objective have been considered developing the procedure: protect the structure against structural damage or collapse and avoid non-structural damage as well as excessive base shear. The compliance is obtained dimensioning dissipative braces to limit global displacements and interstorey drifts. Reference is made to BRB braces, but the procedure can easily be extended to any typology of dissipative brace. The procedure has been validated through a comparison with nonlinear dynamic response of two 2D r.c. frames, one bare and one infilled. Finally a real application, on an existing 3D building where dissipative braces available on market are used, is discussed.

An employee employment of Enterprise must consider efficiency, balance attribute and effectiveness as important variable. but Our country's Enterprise reduce the personnel without basic guide line about employee employment. because Our country's Enterprise thinks of personnel expenses or sales amount decrease as important variable. Therefore, Research background sets out that there is no basic guideline for employment management one of the most important elements in Enterprise administration. and I examined employment control's concept and concept about softness of labor market in theoretical background setting. Also, was abreast of employment control effect, case study and literature research about employment control's basis. Finally, In fluctuation change of Enterprise's employee number, I examined which relation is formed in comparison with sales amount, net profit and the employee number of individual Enterprise using investment analysis material of Stock Company focused on Enterprise that stock is listed on the stock exchange.

This paper proposes a scheme to estimate the technical efficiency of energy consumption and production and shadow prices of $CO_2$ emission in country-level at Asia Pacific countries by Data Envelopment Analysis (DEA). The result of technical efficiency estimation shows that there exists an heterogeneity and a substantial opportunity for improvement in technical efficiency at energy consumption and production across countries, specially in the $CO_2$ emission, which implies that more pollutant are spread in air. Each country will have the different willingness to pay for the additional $CO_2$ emission right and this result enables us to predict the competition in international $CO_2$ emission right market.

The success of movie 'Avatar' make people be interested in 3D stereoscopic movie, and government and 3D industry acknowledge that it is another opportunity to develop 3D market since 1920s. However, despite much interest little research to evaluate the effect of 3D stereoscopic exists. The present research aimed to disclose 3D effect compared to 2D by assumption of the importance of 3D stereoscopic and little evaluation to that as well. When audience are exposed to 3D stereoscopic, many outcomes are supposed to be differentiated from when to 2D. From this hypothesis, this paper examined mood, attitude, and presence as dependent variables. Using polarized stereoscopic projection display, 30 participants watched 2D and another 30 watched 3D stereoscopic movie which were the same content. On conclusion, the two groups were not significantly different and this involved much insight.

The growth of the number of places where technology standardization takes place, and the complex relationships among them, pose challenges for participating actors such as companies and governments. Additionally, it takes considerable resources and capabilities to participate in all Standards Development Organizations (SDOs). Some SDOs have been more effective and efficient in standardizing technologies than others. For this reason, actors need to evaluate and analyze different SDOs to select the appropriate SDO(s) for them and to strategically position themselves in standardizing technologies, so that they can gain more competitive positions in the ubiquitous market. However, it is surprising that there have been relatively few studies analyzing different SDOs. Thus, this study aims to gain insight into the differences and similarities between the methods used at four important international SDOs - IEEE, IETF, OMA, and ETSI - and how these methods are judged by participants. These insights can help governments and companies to develop policies and strategies for SDOs in this changing environment.

Despite the increasing interest in web contents and the rapid growth of CMS(Content Management System) market, the studies on the evaluation criteria for determining the purchase of the CMS solution are very rare. We introduce previous researches on the evaluation models of IT solution, and develop new criteria for evaluating CMS solutions. We calculate the relative importance of the evaluation criteria using scores from the IT experts based on the "Pair-wise Comparison" using the AHP. Based on the analyses of IT specialists′ responses, the results of the study show that, among the ten criteria, "the function of content management", "the contribution to the company′s business process" and "the fit with Information Strategic Plan" are the three most important ones over the remaining others. The developed model and criteria for the evaluation of the CMS solutions are expected to contribute on effective purchasing decision of the solutions and their successful implementation.

Given a fixed production process and facility capacity, the ability to respond to market fluctuations in terms of changes in production, work force, and inventory is the major task of production management. The costs involved are primarily payroll (regular and overtime), inventory carrying, and hiring and firing. The magnitude of these costs is usually a significant portion of the operating costs of the firm and consequently a small percentage saving due to astute aggregate scheduling can mean substantial absolute saving. At least three demonstrably optimal techniques have been developed for solving this aggregate scheduling problem. These three optimal are apparently LDR, PPP, and SDR. By combining these three different approaches, another optimal solution was obtained by me. I call this CDR (Combined Decision Rule). This approach appears to be useful. This approach may be generalizable to aggregate scheduling involving a short term resources.

City gas is becoming an essential resource in households due to its convenience and low price in comparison to other energy sources. However, in order to prepare for the gas market to be saturated, many city gas companies must pursue customer satisfaction management and develop happy call systems for a promising solution. In the development of the happy call systems, the difficult problem is that we cannot contact all customers because of limited resources and calling efficiency in the call center, We should find best customers according to their value. This paper suggests a methodology for the selection of happy call customers when city 9as companies consider two strategies. First, they should launch a new business area. Second, they must attempt to prevent current customers from moving from city gas to other fuels. We will discover important attributes and derive rules of weighting for the attributes through an exploration study that affect customer satisfaction and preference. Through a simulation model, we will show how many customers will be selected by our methodology.
