The current study analyzed the tax structure in the welfare states. The appropriate tax structure of universal welfare state should be based on expanding all taxes, rather than choosing between direct and indirect, progressive and regressive, or mobile and immobile tax. The revenue for the universal welfare payment should be raised by levying tax on all people provided that the welfare payment is made available to all people. The analysis led to classification of tax structure into the high tax European model and the low tax English and East Asian model. The high tax European model was further classified into the balance tax model and the high social security model. The low tax English and East Asian model was classified into the low social security model and the high property tax model. Based on the results, the study maintained that the universal welfare states need not only to expand welfare resources but to develop tax system that corresponds to the universal welfare system.

The aim of this research is to develop a new business model using mobile RFID in exhibition spaces such as museums and art galleries. Using mobile RFID, the exhibition space is expected to be evolved from a simple media space only for the exhibition to an extended space integrating media, commerce and entertainment. This paper proposes a u-Exhibition business model and its scenario in the u-Exhibition space. We discuss the real-world issues for the implementation and show the ways of investigating working conditions for the business model through revenue simulation and analyzing the expected value of tag installed on the exhibition space by so-called 'tag evaluation model.'

We present a methodology for modeling and solving the transit frequency design problem with variable demand. The problem is described as a bi-level model based on a non-cooperative Stackelberg game. The upper-level operator problem is formulated as a non-linear optimization model to minimize net cost, which includes operating cost, travel cost and revenue, with fleet size and frequency constraints. The lower-level user problem is formulated as a capacity-constrained stochastic user equilibrium assignment model with variable demand, considering transfer delay between transit lines. An efficient algorithm is also presented for solving the proposed model. The upper-level model is solved by a gradient projection method, and the lower-level model is solved by an existing iterative balancing method. An application of the proposed model and algorithm is presented using a small test network. The results of this application show that the proposed algorithm converges well to an optimal point. The methodology of this study is expected to contribute to form a theoretical basis for diagnosing the problems of current transit systems and for improving its operational efficiency to increase the demand as well as the level of service.

The purpose of this paper is to provide basic information on how to make better policies that improves efficiencies of urban railways and to derive policy directions using DEA (data envelopment analysis) model. Through this paper, I can identify whether or not the urban railway service has an excellent performance, if there are any structural problems. I analyzed the efficiency by means of measuring the technical efficiencies of Korean urban railways, these were estimated with data envelopment analysis. The inputs considered are the length of urban railway lines, the number of staff, the operating cost, the number of cars, the number of stations, and the outputs are the cars movement, the traffic of passenger, and the revenue.

Purpose: The aim of this study was to analysize net income of a surgical nursing ward in a general hospital. Method: Data collection and analysis was conducted using a performance-based costing and activity-based costing method. Result: Direct nursing activities in the surgical ward were 68, indirect nursing activities were 10. The total cost volume of the surgical ward was calculated at \119,913,334.5. The cost volume of the allocated medical department was \91,588,200.3, and the ward consumed cost was \28,325,134.2. The revenue of the surgical nursing ward was \33,269,925.0. The expense of a surgical nursing ward was \28,325,134.2. Therefore, the net income of a surgical nursing ward was \4,944,790.8. Conclusion: We suggest that to develop a more refined nursing cost calculation model, a standard nursing cost calculation system needs to be developed.

The purpose of this study is to develop and test a model that explains the effect of perceived service factors on: 1) experienced value, 2) trust, and 3) loyalty in context of franchise snack bar. In addition, the study will clarify how these variables relate to each other. The findings of this study identified that functional and humanic clues are the most significant components which influence on experiential value as well as trust in franchise snack bar sector. These findings may contribute to provide valuable marketing strategic for this business segmentation, and it can be utilized as a fundamental study to establish an efficient business plan to increase revenue in the industry.

The purpose of current study is to verify a formulated model that explains the influence of informational clues(Nutritional label information and Mass media information) on subjective knowledge, concern, satisfaction, and behavioral intention toward healthy foods in context of full-service restaurants. The results of present study demonstrated that all informational clues have significant influence on both knowledge and concern about health and the significant relationships were confirmed between knowledge, concern, emotional pleasure, and behavioral intention. This study may contribute to develop meaningful marketing strategic for healthy foods in full-service sector, and it can be utilized as a critical study to establish an attractive business strategics to increase revenue as well as satisfy healthy foods consumers in full-service restaurant consumers.

This paper presents the business model and system functionalities of a B2B e-marketplace solution that not only can overcome some problems of the public e- marketplace, but also can be applicable to both public and private types of e-marketplaces. This solution is different from the most of the public e-marketplace solutions that their main sources of revenue are transaction commissions or transaction fees through the third-party intermediation. Instead, this solution provides an ASP (Application Service Provider) functionality for direct, dis-intermediated purchasing and sales-related transactions between suppliers and buyers. With this functionality, suppliers and buyers electronically commerce with each other without the disclosure of their transactions as well as transaction commissions.

Ubiquitous computing(UC) is an emerging paradigm. Its arrival as a mainstream is expected to trigger innovative UC-driven business models (UCBMs). Currently, there is no Parsimonious methodology to analyze and provide diagnostics for UCBMs. With this research, we propose a analytical architecture that enables the assessment of an UCBM in its structural strengths and weaknesses. With value logic as the cornerstone, the architecture is composed of value actors, value assets, value context, business value Propositions, customer value propositions, value creation logics, and value assumptions. Dimensional variables are initially Identified based on the review of business model literature. Then, their significance is empirically examined through 14 UCBM scenarios, and variables that are expected to Play an important role in the UCBM assessment are decided. Finally, by analyzing the scenarios in terms of the dimensional variables, we attempted to summarize general characteristics of emerging UCBMs.

This study firstly aims to review the discussions among major nations and international organizations on removal of tariff wall in EC. Secondly, it is analyzed how the trend of tariff reduction of removal will affect an individual economy in a partial balance analysis model on an assumed small-size economy. In closing, political implication for removal of tariffs in EC will be presented. The study concluded that tariff removal on Internet EC has both positive and negative effects on the importing economy. It can improve the efficiency in utilization of economic resources by the importing economy in the long term while cut the financial revenue and aggravate the trade balance of importing country. It is inferred from such a conclusion that tariff removal can lead to trade imbalance between the Information haves and the have-nots.
