Characteristics of the motivation and performance of Enterprise Resources Planning (ERP) adoption in university organization are explored through case studies in this study. Generally, the modules for production, sales, and logistics management in a manufacturing company are substituted with new modules for student support, lecture operations, and research management in ERP for university organization. The motivation of ERP adoption is closely related to the purpose of improvement of business process operations and information system control rather than the environmental factors such as inter-organizational competition or increase of market uncertainty, differentially from enterprises cases. In addition, the financial performance such as cost reduction, labor substitution, and increase of productivity is relatively lower evaluated than the performance on organizational aspects or information system control.

For the past years, there had been some environmental cooperation among East Asian countries to reduce air pollution emissions from China. However, the progress of cooperation has been under developed because of lacking financial support, poor design of planning, and weak economic incentives for the industries. In this paper, some practical approaches have been suggested. First, electric trade to make Asian Grid among countries will be good alternatives for the fossil fuel, such as coal, for China. Secondly, natural gas pipeline from West China to Siberian pipeline would change the whole energy mix in this area around 2010, Therefore, it is very promising area for the energy industries to involve in gas project and get rid of many institutional barriers from China. Lastly, environmental industry is growing fast in East Asian. In China, waste treatment and management, air pollution control, and water quality management are some promising areas for the future. Hence it is desirable for Korea, Japan and China to make a eco-fund or company to boost up environmental technology as well as environmental market size.

Agent technology has been widely applied in today's electronic business, such as mobile agents, multi-agent information systems, etc. In particular, multi-agent systems have been applied as powerful simulation tools to study complex business networks composed of various self-interested trading firms and/or human beings. In this paper, we build an integrated model that consists of a multi-agent B2C market model and a B2B trade network model, and incorporate more reality than much of prior work. Then with this model, we carry out experimental studies on two different strategies that are common in electronic business - 'loyal' strategy (retailers try to build stable cooperation with suppiers to ensure material supply) and 'cost-saving' strategy (retailers try to reduce cost by choosing suppliers with lower wholesale price).

Well-known e-CRM strategy is to focus on profitable customers and pay less attention to unprofitable ones. Moreover, some researchers recommend not serving unprofitable ones any more. However, it often neglects customers indirect value. Deselecting unprofitable customers can raise the issue of bad word-of-mouth publicity especially in the age of the Internet. Some studies pointed out that a customers decision to buy a product or service is often strongly influenced by others. In this paper, we consider customers' word-of-mouth effect on quality learning of inexperienced customers. We show that firms implementing e-CRM must take the effect into the consideration when deselecting unprofitable customers.

The present study provides a theoretical investigation on pioneering advantage based on reference dependence and loss aversion effect under prospect theory (Kahneman and Tversky, 1979). Behavioral explanations for pioneering advantage are provided from two different perspectives: one based on the prototypicality and the other on the utility uncertainty of the option. A pioneer brand creates the product category and makes a strong impression in customers' mind, and thus becomes the most representative or prototypical option of the category. In addition, the pioneer brand becomes the first option to be experienced by the majority of consumers in the product category, thus has the lowest level of utility uncertainty compared with the late movers. This study integrates the previous accounts for pioneering advantage by showing that consumers have higher preferences for the most prototypical and the least uncertain option based on loss aversion and reference dependence effect. This study suggests that firms should carefully analyze the consumers' loss aversion and perceived uncertainty and prototypicality of their products in order to develop effective market entry strategies.

Continuous quality improvement has generally been recognized as an essential requirement for a company to stay in business. For this reason, Six Sigma plays an important role In reducing cost and development time of a product and achieving high quality products in a competitive market. The Six Sigma has proven that it is possible to achieve dramatic performance improvement for conducting business. However, several recognized Six Sigma companies have suffered the financial troubles, even if the Six Sigma should be successfully deployed in their business organizations. In this paper, the reason of this paradox is represented and discussed for a successful Six Sigma deployment, including next generation of Six Sigma.

This work is for reasonable valuation method of environmental-friendly and organic company. Reasonable valuation method is principal for the sound development, the reasonable investment and the growth of stock market. This study proposes valid valuation and method for environmental-friendly and organic company. The author selected 4 companies from certificate list of environmental-friendly and organic food and LOHAS (Lifestyles Of Health And Sustainability) food of Korean standards association. Applying financial audit report of 5 years, the author output 5 variables from each companies by using Growth Option model of Real Option model. And the author valuated companies by adding option value calculated with these variables and residual value discounted with cash flow discounted method. Company values from ROV model were 1.71 time higher than DCF model. This results show that the value of environmental-friendly and organic food company may own high option premium, that is the growth factor.

Community residents are tend to evade waste treatment facilities such as waste landfills, waste incinerators. Therefore, decision-makers of waste management are concerned about the reduction and recycling of food garbage. As a treatment alternative of food garbage which consists of 30% of municipal waste, producing compost and feed stuff from food garbage is environmentally amenable. In considering the characteristics of food garbage are putrid and high moisturized, methods of landfilling and incineration for food garbage are environmentally inadequate. For the institutionalization of food garbage recycling, separate discharge, establishment of collection system, securing of market for compost and feed stuff manufactured from food garbage, and tax and financial incentives for food garbage recycling facilities are necessary.

Many Applications of scientific research have coupled with functional data signal clustering techniques to discover novel characteristics that can be used for the diagnoses of several issues. In this article we present an interpretable multi-scale cluster hierarchy framework for clustering functional data using its multi-aspect frequency information. The suggested method focuses on how to effectively select transformed features/variables in unsupervised manner so that finally reduce the data dimension and achieve the multi-purposed clustering. Specially, we apply our suggested method to mutual fund returns and make superior-performing funds group based on different aspects such as global patterns, seasonal variations, levels of noise, and their combinations. To promise our method producing a quality cluster hierarchy, we give some empirical results under the simulation study and a set of real life data. This research will contribute to financial market analysis and flexibly fit to other research fields with clustering purposes.
