Based on investigating and analyzing the cases of advanced foreign universities that have already included ERP courses in their education systems, this study proposed the ways of incorporating ERP courses into Korean universities' curriculums in terms of the following three areas: 1) development of ERP courses, 2) establishment and maintenance of ERP education environment, 3) continuous evaluation and improvement of ERP education implementation. As reasonable ERP courses, "Introduction to ERP" targeted to educating overall basic concepts in ERP system and business administration, "ERP System Implementation" for fostering business process design and system implementation skills, "ERP Programming" such as ABAP for the purpose of customizing ERP system, and "Strategic Use of ERP" dealing with ERP package selection and implementation methodologies of effective utilization of ERP systems were suggested. Regarding the establishment and maintenance of ERP education environment, single server architecture model that contained both database and application was proposed with the intention of set-up cost saving and maintenance efficiency. As for the evaluation and improvement on ERP education implementation, its methodologies were introduced through analyzing the advanced cases. Finally in addition to the above three areas, critical success factors for effectively launching ERP education in the universities were suggested through reviewing the previous case studies.

This study is to identify the maintenance service quality of eco-friendly cars, which are rapidly increasing recently. Research is conducted by synthesizing research from the perspectives of internal employees and external customers by using the service profit chain model. Specifically, it is to study the overall structural relationship between internal customer satisfaction, physical quality, interaction quality, outcome quality, external customer satisfaction and long-term orientation. For the study, 202 questionnaires were collected from internal employees and 204 questionnaires from external customers. The results of testing the research hypotheses targeting the internal employee group are as follows. As a result of testing hypothesis 1, internal customer satisfaction has a significant positive (+) effect on physical quality and interaction quality. As a result of testing hypothesis 2, the service quality of eco-friendly car maintenance has a significant positive (+) effect on each other. As a result of testing hypothesis 3, physical quality and outcome quality have a significant positive (+) effect on external customer satisfaction. The results of testing the research hypotheses targeting an external customer group are as follows. As a result of testing hypothesis 2, in the relationship between eco-friendly car maintenance service quality, physical quality has a significant positive (+) effect on interaction quality, and interaction quality has a significant positive (+) effect on outcome quality. As a result of testing hypothesis 3, interaction quality and outcome quality have a significant positive (+) effect on external customer satisfaction. As a result of testing Hypothesis 4, external customer satisfaction has a significant positive (+) effect only on intention to reuse. Finally, as a result of examining the difference in perception between the internal employee group and the external customer group in eco-friendly car maintenance service quality and external customer satisfaction, it was verified that there was a significant difference only in outcome quality and external customer satisfaction.

The importance of data management for the efficient maintenance and operation of offshore structures is becoming increasingly important. This paper has discussed the data schema and business rules that standardize the data exchange between ship design, operation and maintenance. Technical documentation that meets the international standards of ShipDex and S1000D for exchanging the operation and management data in neutral or standard formats has been introduced into the life cycle management of ships. The schema of the data exchange is represented by XML (eXtensible Markup Language) and the lifecycle data is implemented by a structured document. Lifecycle data is represented as data modules defined by XML schema. Given the feasible data generation, an example of a technical document is introduced by a general XML authoring tool.

Remarkably improvements have occurred recently in the maintenance management of physical assets and productive systems, so that less wastages of energy and resources occur. The technology of maintenance is about finding and applying cost-effective ways of avoiding or overcoming performance deterioration. Maintenance is thus a vital support function in business, especially as increasingly large investments are being required in physical assets. TPM(Total Productive Maintenance) focuses on optimizing planning scheduling. Availability, performance and quality rate are other factors that affect productivity. Especially there are some losses that affect the overall equipment effectiveness(OEE). These losses lead to low values of OEE, which provides an indication of how effective the production precess is. This study explores the ways in which Korean small and medium manufacturing industries can improve OEE.

This paper is to analyze and provide some managerial requirements for the successful implementation of total productive maintenance system. It tries to identify determining factors for success and reasons for the failures of TPM, based on the research of a survey and an empirical study through the years in Korea. The findings are such that many companies have not been engaged in planning and control the maintenance cost and their maintenance activities are not organized systematically. However, many indicators show that the number of finns which try to introduce and implement TPM is getting increased. The successful implementation of TPM depends largely on how top management perceives TPM and how the firm responds In the changes of organization and of the role of workers to adapt this new concept of work. It is required that TPM is perceived as a means to achieve the firm's business objectives. It is recommended that each company constructs and develops its own model and procedures to drive the effort for TPM implementation.
