Given the large investment and prevalence of knowledge management (KM) in organizations, it has become important to analyze the effects of KM activities on organizational performances. A theoretical framework is proposed to investigate the impact of KM activities on innovation capabilities in the IT service industry. This study considers KM activities as the major determinant that enhances absorptive capacity. KM activities enhance employees'ability to obtain external knowledge, resulting in increasing intellectual capital. Thus, this study proposes that absorptive capacity plays a mediating role between KM activities and innovation capability. Additionally, this study investigates the key antecedents of KM activities that promote employees' knowledge sharing. Based on prior studies on KM, this study posits KM team activities and top manager support as KM activities. The proposed research model was tested by using survey data collected from 556 employees in the IT service industry. PLS (partial least squares) was employed for the analysis of the data. The findings of this study showed that KM activities and absorptive capabilities play a significant role in enhancing service innovation and process innovation in the IT service industry. The results also shed light on the mediating role of absorptive capacity between KM activities and innovation capability. Moreover, both KM team activities and top manager support serve as the salient antecedents of promoting employees' knowledge sharing.

The purpose of this paper is to examine the differences in the critical success factors for ERP adoption suggested by the system managers and the ERP consultants. The survey results indicated the following findings. First, there was no significant difference in the relative importance of the critical success factors between the system managers and the ERP consultants. Both groups agree that 'top manager's concern and support' is the most critical factor and that 'user involvement' is the second. However, the system managers tend to think 'training and education of end users' and 'cooperations among the project participants' more important than the consultants do. Second, both groups agree that the most important ERP contribution should be 'improvements in the business processes.' They also agree that the least important aspect is 'ERP's contribution to the individual's productivity.' In overall, the ordered lists of ERP evaluation criteria according to their importances were of no significant difference between the groups. Third the two groups showed differences when they were asked to evaluate the importance of the critical success factors for each of the ERP evaluation criterion. In general, the system managers tend to put more emphasis on 'training and education of end users' and 'adaptation of end users to the changed processes,' whereas the consultants tend to emphasize more on 'top managers' interest and supports' and 'project manager's capabilities and performance.' The differences in the critical success factors presented by the two groups indicated that more efforts need to be devoted to understanding other participant's interests and concerns in an ERP project team. Better coordinations based on the mutual understandings could improve the chance of achieving a success in adopting ERP packages.

Japanese manufacturers have seen the market swing from a sellers' market to a buyers' market by dint of changes in the economic environment. Therefore, they have found the need to establish a production system in which products can be manufactured at the speed at which they are being sold and which achieve a competitive advantage. FA activity in Japan today has begun to change from local automation to totally integrated automation. This paper introduces a bottom to top based JIT-FA system and describes how to approach and introduce a CIM supported by human based systems. A fully automated CIM system is not only flexible but also rigid. However we can realize a flexible production line system by partially introducing human based systems including a decision support system.

Background : It is increasing the concern for patient satisfaction as a customer information. This study was planned to investigate the activities related to patient satisfaction survey at the Korean hospitals. Methods : We performed the nationwide survey on 235 general hospitals by using the self-administrated checklist from Sep. 9 to Oct. 9, 1996. The response rate were 50.2%. We analyzed the descriptive statistics and chi-square test by SAS software on 118 hospitals. Results : First of all, 62.7% of study hospitals showed to conduct the patient satisfaction survey, and most of hospitals which did not conduct it had a plan to do it within 5 years. The reason that hospitals did not conduct satisfaction survey was due to a lack of administrator's interest or adequate questionnaire form. Second, the bigger, public and being more located in the big city or opened more than 10 years, the more hospitals conducted the patient satisfaction survey. Also, patient satisfaction survey was mainly handled by planning dept. or administrative team. Third, most hospitals had their own way of making questionnaires without proving reliability and validity. The results of the survey were applied to hospital management timely, and were mostly reported to top manager level. Most CEO concerned about the results of satisfaction survey. Fourth, the staffs in charge of survey had problems such as skill related to data analysis and development of questionnaire and they suggested that this problems could be solved through inducing the implementation of the survey results on hospital management, support for the development of standardized questionnaires and increasing the top manager's interests. Fifth, most questionnaires composed of lots of questioning items on hospital equipments and environment, and kindness of hospital employee to patients. Conclusions : Although this study had some limitations in generalization due to low response rate in big hospitals, it is meaningful to find the present state and the problems related to patient satisfaction survey of the general hospitals. We can conclude that there are increasing the concern for patient satisfaction survey among the hospitals nationwide, and it can be needed for technical support related to development of survey tool or method.

The information technology(IT) development of telecommunication, along with the informationalization over the world, enables the firms to process their inner and outer operations through Electronic Data Interchange (EDI) system. And the concept of logistics has become more important to the enterprises in strategic sense because it had aggrandized itself to more comprehensive and integrative concept. Also the world shipping market is more competitive than any other market. In these environment, to maintain competitve power, shipping firms process operations by Logistics Information system(LIS), And then, reduce the working processes, working time and its costs. So the LIS has become more important in developing our national logistics system and industry. Therefore, this study purposes on empirically analyzing the activation factors of shipping LIS and the relationship these factors with logistic performances in the shipping industry. Considering environments of Shipping logistics information system, this study sets up the research model and hypothesis to examine the activation factors of shipping LIS and the relationship these factors with logistic performances. We used the field data on the 163 numbers of firms(29 overseas shipping companies and 133 forwarding Agency) to get the empirical evidence. According to the study results, The shipping LIS activation factors which the sample firms recognized as important: were top manager's support, well structured communication channel, strategic plan's connection and inner informationalization level. And IS organization ＆ human resources, IS discipline ＆ training, software development, IS organizational alignment, database management system, information standardization, competitive advantage, financial support and government support represent partially significant. Also, the current shipping LIS's main problems are expensive system cost, standardization of working process's, institution's imperfection and system's interaction defect. So these problems must be improved to activate shipping LIS.

In this paper, we arrange the concept of 'Green' in SCM after literature study of Green SCM and investigate causal relationships between influencing factors, practice level and environmental performance focused on Korean firms empirically and conduct path analysis for hypothesis test using partial least squares regression with bootstrap. Firstly, we divide influencing factors of Green SCM into environmental and organizational factors through the previous studies of innovation diffusion theory and environmental management theory, and then we selected 'uncertainty', 'competitiveness' as the environmental factors and 'top management support', 'perceived benefit', 'training' as the organizational factors. Secondly, we classify practice level of Green SCM into 'internal environmental management', 'green purchasing', 'eco-design'. Finally, we selected 'financial performance', 'environmental performance' as the organizational performance. We conducted a survey on the middle manager of manufacturing companies implementing SCM and an empirical analysis. The results of analysis show that there exist causal relationships between influencing factors, practice level, and environmental performance of Green SCM. We expect that the result of this study will suggest useful information to managers who are responsible for SCM to design and execute Green SCM in strategic perspectives.

Purpose - The purpose of this study is to predict corporate corruption in emerging markets such as Brazil, Russia, India, and China (BRIC) using different machine learning techniques. Since corruption is a significant problem that can affect corporate performance, particularly in emerging markets, it is important to correctly identify whether a company engages in corrupt practices. Design/methodology/approach - In order to address the research question, we employ predictive analytic techniques (machine learning methods). Using the World Bank Enterprise Survey Data, this study evaluates various predictive models generated by seven supervised learning algorithms: k-Nearest Neighbour (k-NN), Naïve Bayes (NB), Decision Tree (DT), Decision Rules (DR), Logistic Regression (LR), Support Vector Machines (SVM), and Artificial Neural Network (ANN). Findings - We find that DT, DR, SVM and ANN create highly accurate models (over 90% of accuracy). Among various factors, firm age is the most significant, while several other determinants such as source of working capital, top manager experience, and the number of permanent full-time employees also contribute to company corruption. Research implications or Originality - This research successfully demonstrates how machine learning can be applied to predict corporate corruption and also identifies the major causes of corporate corruption.
