Case-based Reasoning (CBR) is widely used in business and industry prediction. It is suitable to solve complex and unstructured business problems. Recently, the prediction accuracy of CBR has been enhanced by not only various machine learning algorithms such as genetic algorithms, relative weighting of Artificial Neural Network (ANN) input variable but also data mining technique such as feature selection, feature weighting, feature transformation, and instance selection As a result, CBR is even more widely used today in business area. In this study, we investigated the usefulness of the CBR method in forecasting success in implementing ERP systems. We used a CBR method based on the feature weighting technique to compare the performance of three different models : MDA (Multiple Discriminant Analysis), GECBR (GEneral CBR), FWCBR (CBR with Feature Weighting supported by Analytic Hierarchy Process). The study suggests that the FWCBR approach is a promising method for forecasting of successful ERP implementation in Small and Medium sized Enterprises.

Recently, due to the continuous changes in the business environment and increased competition, enterprises are introducing technology management to increase their value and enhance their competitiveness. In this study, based on the structural equations model, we investigated the effects of the core success factors of knowledge management on job fidelity and organizational performance and the mediating effects of organizational learning. In addition, organizational culture and information technology and process were assumed to be the key factors affecting knowledge management, and organizational learning was represented by experimental learning, indirect learning, and shared learning. As a result, it was found that knowledge management positively affects business fidelity and organizational performance and, even when it is mediated by organizational learning, it positively affects business fidelity and organization performance directly or indirectly. Therefore, we were able to confirm the importance of utilizing knowledge management in companies and to suggest an appropriate application scope for applying knowledge management and organizational learning.

The purpose of this study is to examine the priorities of innovation activities, business performance, and maximization factors of SMEs. Support programs for each government department are operated by various industries. Various supports, including subsidies, grants, marketing, planning, and education, are provided to each company. Therefore, this study aims to analyze and identify the priorities of innovation activities that have a positive effect on business performance. The efficacy of the proposed model and the psychometric properties of structure were analyzed using the analytic hierarchy process (AHP). The hierarchical structure of corporate innovation activities are composed of 'R&D' and 'government support', and 'Inside R&D, Outsourcing R &D, Consortium R&D'. As a result of analyzing companies that received more than one type of R&D government support, it can be seen that 'government support' (72.1%) is more important than 'research and development' (27.8%). In addition, this study found key sub-factors loadings including Assistant Support (30.1%), Tax Support (22.7%), Funding Support (18.8%), Inside R&D (10.8%), Outsourcing R&D (10.3%), and Consortium R&D (7.2%). Analysis results suggest that the priorities of detailed innovation activities of R&D and government support affect product innovation and process innovation, which in turn, influence business performance and maximization of SMEs. This implies that SMEs who want to participate in the government support project will be helpful in setting the direction of innovation activities. This study also suggests the importance of strategic priorities among the decision elements for CEOs.

A novel transflective-type LC mode with good display performance has been developed In order to drive both transmissive and reflective modes simultaneously without any modulation of gamma in a single-gap structure, we have introduced a new design concept in the reflective region, where the capacitance is separated into liquid crystal($C_{LC}$} and organic layer($C_{OL}$), playing a key role as a voltage divider in our cap-divided VA-mode. With this cap-divided method having both merits of simplifying process and good legibility, we have achieved good optical characteristics such as high contrast ratio and wide viewing angle in a single-gap homeotropic panel design.

Purpose - This study seeks to find out the factors affecting the performance of franchisees from the franchisor's and franchise's intangible assets. In order to explain the process, this study explores the concept of LMX, Relational Capital, and Decision Rights Delegation. Research design, data, and methodology - To verify the proposed hypotheses, a questionnaire survey was conducted for franchise store owners, and to test the hypotheses, structural equation modeling was established. Results - First, franchisor's intangible assets affect the quality of LMX, but don't affect the relational capital. And the quality of LMX affects the relational capital. In addition, "the effect of delegation of decision rights on relational capital" and "the effect of relational capital on franchisee's performance" were significant. However, the effect of delegation of decision rights on franchisee's performance wasn't significant. Second, the intangible assets of the franchise have a positive effect on the quality of the LMX and the degree of delegation of decision rights, and the quality of the LMX has a positive effect on the delegation of decision rights. Conclusions - This study would suggest operational implications for the formation of vertical and horizontal relationships and the cooperation between the main members of the franchise business.

This study empirically analyzes the impact of inventory management performance on the energy efficiency in Korean petrochemical companies. The concept of the distance function is used to define the energy efficiency and the estimation of the distance function is performed using the stochastic frontier analysis. The inventory turnover is selected as the variable indicating the inventory management performance of the company. The main results of this study are as follows. First, the inventory turnover has a positive impact on energy efficiency. Second, during the period over 2011~2015, while the gap in energy efficiency among the companies expanded, the average energy efficiency decreased. Third, the average energy efficiency in upstream process companies was greater than downstream process companies and the gap in energy efficiency among downstream process companies was greater than upstream process companies. Fourth, the average marginal effect of inventory turnover on energy efficiency increased gradually from 2011 to 2015. Finally, the average marginal effect of inventory turnover in downstream process companies was greater than upstream process companies, and the gap in the marginal effect of inventory turnover among downstream process companies was greater than upstream process companies. These results together imply the importance of inventory management in terms of energy efficiency.
