There are big differences in six sigma projects between manufacturing processes and transactional/service processes. This paper analyzed the differences between the two areas by examining 18 six sigma case studies in Korean companies. To characterize six sigma case studies, step-by-step questions and check criteria were developed based on 12 step DMAIC methodology. On the basis of those characterized data, the differences between two areas were analyzed. Significant differences were found in the number of CTQs, validation of measurement systems, methods to determine improvement objectives, the methods to elicit improvement plans and types of control systems. The most significant difference was that statistical tools were widely used in manufacturing processes, but qualitative tools were used in transactional/service processes during improvement phase.

In Web Service Composition (WSC) area, services selection aims at selecting an appropriate candidate from a set of functionally-equivalent services to execute the function of each task in an abstract WSC according to their different QoS values. In despite of many related works, few of previous studies consider transactional constraints in QoS-aware WSC, which guarantee reliable execution of Composite Web Service (CWS) that is composed by a number of unpredictable web services. In this paper, we propose a novel global selection-optimal approach in WSC by considering both transactional constraints and end-to-end QoS constraints. With this approach, we firstly identify building rules and the reduction method to build layer-based Directed Acyclic Graph (DAG) model which can model transactional relationships among candidate services. As such, the problem of solving global optimal QoS utility with transactional constraints in WSC can be regarded as a problem of solving single-source shortest path in DAG. After that, we present Graph-building algorithms and an optimal selection algorithm to explain the specific execution procedures. Finally, comprehensive experiments are conducted based on a real-world web service QoS dataset. The experimental results show that our approach has better performance over other competing selection approaches on success ratio and efficiency.

The purpose of this study is to derive practical implications by verifying the influence of MSME owners' leadership type and management performance on knowledge management. In addition, we tried to verify the mediating role of knowledge management between the leadership type and management performance of MSME owners. Leadership types were divided into transformational leadership and transactional leadership. Transformational leadership consisted of charisma and inspirational motivation, while transactional leadership consisted of situational rewards and management by exception. For data collection, we conducted a survey targeting workers in small businesses. After excluding insincere data that were inappropriate for analysis, we used the remaining 243 samples for empirical analysis. To test the hypothesis, we adopted regression analysis and three-step mediated regression analysis as analysis methods. As a result of the empirical analysis, all seven hypotheses derived were supported, and the main results are summarized as follows. First, we found that MSME owners' transformational leadership and transactional leadership had a positive effect on knowledge management and management performance. Second, we found that knowledge management of MSME owners had a positive effect on business performance. Third, both transformational leadership and transactional leadership of MSME owners were found to be partially mediated by knowledge management in relation to management performance. Based on these research results, we derived practical implications for MSME owners.

Pervasive computing is characterized by a key characteristic that affects the operating environment of services and users. It places more emphasis on dynamic environments where available resources continuously vary without prior knowledge of their availability, while in static environments the services provided to users are determined in advance. At the same time, Cloud computing paradigm introduced flexibility of use according to the user's profile and needs. In this paper, we aimed to provide Context-Aware Transactional Service applications with solutions so that it can be integrated and invoked like any service in the digital ecosystem. Being able to compose is not enough, each service and application must be able to offer a well-defined behavior. This behavior must be controlled to meet the dynamicity and adaptability necessary for the new user's requirements. The motivation in this paper is to offer design patterns that will provide a maximum of automatism in order to guarantee short reaction times and minimal human intervention. Our proposal includes a cloud service model by developing a PaaS service that allows CATS adaptation. A new specification for the validation of CATS model has been also introduced using the ACTA formalism.

Today's rapidly changing healthcare environment and increasingly professional nursing practice indicate that identifying leadership characteristic of nursing leaders and executives is a vital importance in today' s time and also mandate innovative leadership for nursing service. Therefore, the purpose of this study is to examined the transformational, transactional leadership styles of the Nurse Administrators. The sample consisted of sixteen mid-level nurse administrators, fifty head nurses of 5 General Hospital. Data for this study was collected from Sep. 20 to 29 by Bass' MLQ Questionnaire. The data was analyzed by frequency, percentage, one-way ANOVA. Major findings are as follows : Appropriate one-way ANOVA tests revealed that the differences for transformational and transactional leadership styles of nurse executives, mid-level nurse administrators as perceived by their immediate subordinates were statistically significant(P<.05). The scores of transformational and contingent reward behaviors were declined of the mid-level nurse administrators. The transactional scores of nurse administrators were lower than transformational ones, which is a desirable findings. The result of this study, the mid-level nurses administrators were perceived as the highest transformational leader by their subordinates. The nurse executives received the lower transformational leadership scores than mid-leval administrators. These results were opposit to the previous studies. Leader can aspire to these qualities of transformational leadership, building on the more traditional transactional dimensions. We can think that transformational leadership suggests a direction for developing a creative and rewarding approach to the leadership of professionalnursing practice environments. More research on transformational qualities in nursing service and controlled designs would be desirable for nursing service administration.

Despite the fact that much has been published about Six Sigma in the business and academic press and on the Internet in recent years, there is still confusion among many people, particularly those who work in the transactional and service environments, about the nature of Six Sigma. It is true that Six Sigma like other process improvement programs before was first applied to manufacturing processes; however, many corporations including General Electric and Sony have successfully applied Six Sigma to their transactional and service processes as well. Six Sigma is used by many companies not only to improve the quality of their products and services but also to achieve quantifiable financial results, improve management style and communication, and achieve customer and employee satisfaction. Whether in manufacturing or non-manufacturing environments, the application of Six Sigma differs from organization to organization. Although there are many common elements between these applications, however, special care must be taken when customizing Six Sigma to suit the organizations' needs. In this paper, the author provides some practical and useful guidelines for Six Sigma deployment. This paper is not about the use of numerous statistical tools and techniques that can be found in a typical Six Sigma toolbox. The main emphasis has been placed both on the concept and the implementation of Six Sigma, particularly within the non-manufacturing areas of business.
