Software maintenance is an important and very expensive activity in software life cycle. To estimate the maintainability cost of software, many software metrics have been proposed. This paper presents the result of an experimental study to explore the relationship between maintainability and some software metrics. LCOM, RFC, DAC, and LOC are employed as metrics and time really spent for maintenance activity has been collected. In the experimental study, we have found that for some systems, the existing metrics may not be an indicator to maintenance effort, which is not consistent with our general knowledge on the relationship between them. Specifically speaking, we recognized that there should be more empirical study on the relationship between metrics and maintainability of softwares which have been developed using recent technologies such as software architecture and design pattern.

The purpose of this research is to examine the effect the motives for participating in lifelong education and involvement on lifelong education have on the learners' satisfaction from lifelong education, the continuous intention to take courses, and the intention to recommend lifelong education. The results from a quantitative research show that the practical and recreational motives had a high positive correlation to situational involvement in lifelong education and that the relational and goal-oriented motives had a high positive correlation to continuous involvement in lifelong education. Moreover, for satisfaction about teaching methods, practical motives had a relatively higher effect. For satisfaction about facility comfort, recreational motives had a relatively higher effect. For satisfaction about communication, relational motives had a relatively higher effect. For satisfaction about contents' quality, goal-oriented motives had a relatively higher effect. The finding also shows that situational involvement had a relatively higher effect on satisfaction about contents' quality. Continuous involvement had a relatively higher effect on satisfaction about teaching methods.

First of all, There are direct effects among LGO, creativity, working smart, and work performance. However, working hard didn't have any direct effect with any other variables. Creativity and working smart have indirect effects on the relationship between LGO and job performance. In addition, the mediating effect of the model with creativity was higher than that of the model without creativity. Therefore, creativity is an individual competency that should be continuously developed to improve the work performance of a salesperson.

There are some advantages of developing applications based on the object oriented concepts. One os them is that it is possible to reuse the existing designs and products. This paper provides a formal method for the reorganization of class hierarchies for the object extension in the object oriented design phase. In this paper, we introduce classes, and edges to represent the inheritance and aggregation relationship between classes. Based on the graph, we define an order relation(called the object extension) between class hierarchy graphs. And also we present a set of five basic transformations preserving the object extension relation. The set is proven to be correct and complete. The results of this paper help form a theoretical basis for the extension and reorganization object-oriented application systems.
