Authors have developed the method of selecting the efficient variant of designing a systems or products from a some number of competition variants in the conditions of vagueness of the initial information. Registration of information vagueness degree concerning the quantity index values is carried out of the expense of giving to the expert the possibility of using different methods of index evaluation numerical evaluations with physical scale; phrases of limited language; and points evaluation. Using of this method and software is important for marketing research, for systems of quality control of products.

One of the major challenges confronting a multiservice electric utility is the establishment of the right prices, for its services. The key objectives of particular pricing schemes are reasonableness of company earnings. Economic efficiency, the responsiveness of supply and of the allocation of sources to the desires of consumers, and maintenance of some degree of competition. This paper proposes a value-based pricing mechanism amenable to the current deregulation situation in electricity market allowing service differentiation. The proposed pricing mechanism can be implemented ina nodal auction model, and can also be applied to direct load control.

Despite competing strategical interests over Southeast Asia that have emerged in the last decade, with the launch of wide scope geopolitical strategies Chinese and Japanese initiatives have been characterized by a certain degree of implicit coordination, particularly in offering support to the Myanmar state's territorializing strategies for economic development. The case of the Thilawa Special Economic Zones (SEZ) is exemplary, as it was a Japan-led project which became a model and benchmark example for similar development initiatives supported by the People's Republic of China.

As different service classifications for existing and new business data services, it is hard to gather necessary data for the service providers to set their strategies and regulations are also applied asymmetrically to each service provider. Therefore an appropriate market classification is required for the business data services. The Hendry model is selected in this paper to analyze substitution degree among services and then Hendry model is applied to competition among four business data services. As a result, it is shown that these services compete directly and future market shares of services are forecasted and positioning strategy for new services is considered.

In a rapidly changing business environment, the improvement of managerial techniques through IT utilization brings about remarkable increases in profitability and redesign of work process for better performances. IT innovation by electronic instruments such as ICT e-business provides accelerates forming inter-organizational information network and helps them benchmark the best practices of advanced organizations. A new shift of paradigm by e-business across all enterprises has turned the traditional aspects of inter-organizational competition and relationship into a form of collaboration. Collaboration enables business activities in parallel position among companies and facilitates cooperation between partner enterprises. Lately, the concept of 'Synchronization' is emerging beyond dimension of cooperation between networks, and the most concepts related to it are converging into 'Collaboration Networks'. This research observes a virtual organization as a form of collaborative networks, and measures the degree of virtualization of Korean collaborative organizations.

The effects of rate of phase separation to ester interchange reactions and the repulsive pair interaction energy on the phase behavior in a phase-separated immiscible polyester blend are investigated using a Monte Carlo simulation method. The time evolution of structure factor and the degree of randomness are monitored as a function of homogenization time. When the phase separation is dominant over ester interchange reactions, the domain size slowly increases with homogenization time. However, when the pair interaction becomes less repulsive, the domain size does not significantly change with homogenization time. On the other hand, when ester interchange reactions are dominant over the phase separation, the homogenization proceeds without a change in the domain size. The higher the extent of phase separation, the lower the increasing rate of the DR. However, when the phase separation is sufficiently dominant, the effect of the extent of phase separation on the increasing rate of the degree of randomness become less significant.

With the increase of global competition and the reduction of the lifecycle of business process, most leading companies begin to adopt BPO(Business Process Outsourcing), by outsourcing the whole or part of their business process to external service providers and focusing on their core capability, in order to enhance their core competency, In adopting BPO, it is an important decision-making issue that which part of process should be outsourced. So identifying core/non-core process among the business processes is a prerequisite for managing corporate capability and performance of outsourcing. In this study, by focusing on knowledge intensity and degree of informatization of the business process that are important factors in adopting BPO, we have analyzed the current status of BPO adoption of domestic firms and proposed several guidelines for adopting BPO.

The protonation of tetraphenylporphyrin (TPP) in acidic organic solutions was analyzed by acid titrimetric and temperature-dependent absorption measurements. Competition between the protonation of free base TPP $(TPPH_2)$ and the solvation of proton by near solvent molecules determines the equilibrium of the diprotonated TPP $(TPPH_4^{2+})$ formation. The diprotonated TPP exists as an ion pair complex with the acid counterions, which are found to affect the degree of red shift of the Soret band. The rotation of the phenyl rings also plays an important role in the diprotonation, as suggested by the decrease in the degree of diprotonation for the fluorophenyl TPP derivatives whose phenyl ring rotation is significantly hindered relative to normal TPP. The difference of fluorescence lifetime between $TPPH_2 \;({\pi}_{FL}=19.6\;ns)\; and\; TPPH_4^{2+} \;({\pi}_{FL}=2.1 \;ns)$ was used advantageously to measure the rate of protonation in the excited state. The protonation of TPPH2 are found to occur much slower than the diffusion of protons from bulk solution to the porphyrin ring. The monoprotonated TPP is suggested to be the transient species for the diprotonation process.

I wish to examine plan about megalopolis formation with Japan and Busan, possess location condition that can be injured to center hub of North-east Asia. First for this, through competitive analysis of Korea and Japan in industrial structure, I will search competition relation. Second, examine what exports and specialization industry of two area are, through industrial structure of Busan and Kyushu area of Japan. Third, to form megalopolis, wish to present what business belt that can bind two area. Fourth, I wish to present preview point about this study in the conclusion. Examine from 2004 to 2007 through exports, degree of trade join(combination), index of trade specialization degree, index of Revealed comparative advantage, and etc, for analysis of this study how in changed industry competitive between two countries or two area have changed.

This paper examines how a Korean automobile firm price-discriminates between the Korean and the U.S. markets. We argue that a Korean automobile firm's pricing behavior depends on the differences in price elasticity over the segmented markets between the countries. Our findings are that differences in price elasticity may help explain why a medium-class car's price is higher in Korea than that in the U.S. while a small-sized car's price is higher in the U.S. than in Korea, which implies that a Korean automobile firm $3^{rd}$ degree price-discriminates on the same or similar products between Korea and the U.S. This type of $3^{rd}$ degree price discrimination differs from a typical home-bias effect (charging higher prices to domestic consumers) because a small-sized car which is produced domestically sells at higher price abroad. This finding can be added as a source that violates the law of one price.
