Recently. interests in IT Service Management (ITSM) are increasing internationally as well as domestically. In order to realize the benefits from ITSM, it is necessary to institutionalize it as a culture of the organization through effective change management. One of the most promising approach of effective change management is a Six Sigma technique. In this study, we analyze a success case in which 6 Sigma was applied to Service Desk function which is one of the most important functions of ITSM. Through the analyses, this study aims to propose a feasible and specific approach to institutionalize ITSM. To accomplish the objective. the study analyzed specific methods of application of 6 Sigma to ITSM. performance of the project and future directions based on interview and project document/deliverable review. This study could not provide detailed performance measures due to lack of previous research on this topic and difficulty of obtaining quantitative data. However. this study has contributed to proposing a direction to institutionalize ITSM in organizations by analyzing a feasibility of 6 Sigma in implementing ITSM.

Contract design plays a key role in the life cycle of BOT project. All project management activities and operation processes are arranged in consistence with the document of BOT contract which the public sector ensures that the respective roles and responsibilities set out in the contract are fully understood and fulfilled to the contracted performance criteria. With limited theories to deal with some fundamental issues of BOT contract design, we try to collect data from case studies and formulate several practical principles. The conclusions presented in this paper are analyzed from two cases, one is based on an early case in the United Kingdom, and the other based on the Taiwan High Speed Railway case. The purpose of this paper is not about covering all legal issues about BOT contract design, but rather, our work provides common considerations applicable to the contract parties of a broad range of BOT contracts. The results in this paper shall propose some fundamental principles of the BOT contract design.

String matching is one of the key algorithms in network security and many areas could be benefit from a faster string matching algorithm. Based on the most efficient string matching algorithm in sual applications, the Boyer-Moore (BM) algorithm, a novel algorithm called RQS is proposed. RQS utilizes an improved bad character heuristic to achieve bigger shift value area and an enhanced good suffix heuristic to dramatically improve the worst case performance. The two heuristics combined with a novel determinant condition to switch between them enable RQS achieve a higher performance than BM both under normal and worst case situation. The experimental results reveal that RQS appears efficient than BM many times in worst case, and the longer the pattern, the bigger the performance improvement. The performance of RQS is 7.57~36.34% higher than BM in English text searching, 16.26~26.18% higher than BM in uniformly random text searching, and 9.77% higher than BM in the real world Snort pattern set searching.

Recently, interests in IT Service Management(ITSM) are increasing internationally as well as domestically. In order to realize the benefits from ITSM, it is necessary to institutionalize it as a culture of the organization through effective change management. One of the most promising approach of effective change management is the change management framework of ITSM. In this study, we analyze a success case in which the change management framework of ITSM was applied to IT Service company which has introduced ITSM. Through the analyses, this study aims to propose a feasible and specific approach to institutionalize ITSM. To accomplish the objective, the study is designed to analyze specific methods for applying ITSM's change management framework to ITSM organizations, performance of projects and future directions based on interviews and review of project documents/deliverables. This study could not provide detailed performance measures due to lack of previous research on this topic and difficulty of obtaining quantitative data. However, this study has contributed to proposing a direction to institutionalize ITSM in organizations by analyzing a feasibility of ITSM's change management framework in implementing ITSM.

This paper provides a case for the comprehensive performance management system in Public Procurement Service. Public Procurement Service set up the BSC system at the beginning of 2006 by improving and complementing the earliest performance management system and made it possible to automatically connet the performance measurement and evaluation of the departmental and person by using CSF and KPI, which result from their mission and strategic assignments. Therefore, the public service of the adminstration is able to offer better customer service, as the private corporations do, apply the incentive and disincentive policies to the personnel and reward administration and contribute to changing the administration into an organization of competition and performance compensation. The application of the BSC system enables the strengthening of the individual evaluation system in the departmental, integration of various evaluations into one, and the establishment of a monitering system of achievement rate in the objective management in the periodic results. Such a case study of Public Procurement Service will determine the course of establishment of the BSC in other public institutions and suggest many successful methods and ideas for the performance management system.

The importance of IT service management to improve the effectiveness and efficiency of IT outsourcing practices or performance has been emphasized in the fields. Accordingly, several methodologies of IT service management have been adopted in a fashion. This case based research tries to analyze the effects of ITIL-based IT service management practice in a company on IT outsourcing performance. The case analysis shows that ITIL-based service management influences systems quality, information quality, and service quality in direct manner. But it does not influence systems use and systems satisfaction in a meaningful way. This study would help IT service managers construct IT service environment which improves the performance of IT outsourcing service delivery and also researchers set up research proposition in a concise way in the future.

The finance-investment industry is currently focusing on research related to artificial intelligence and big data, moving beyond conventional theories of financial engineering. However, the case of equity optimization portfolio by using an artificial intelligence, big data, and its performance is rarely realized in practice. Thus, the purpose of this study is to propose process improvements in equity selection, information analysis, and portfolio composition, and lastly an improvement in portfolio returns, with the case of an equity optimization model based on quantitative research by an artificial intelligence. This paper is an empirical study of the portfolio based on an artificial intelligence technology of "D" asset management, which is the largest domestic active-quant-fiduciary management in accordance with the purpose of this paper. This study will apply artificial intelligence to finance, analyzing financial and demand-supply information and automating factor-selection and weight of equity through machine learning based on the artificial neural network. Also, the learning the process for the composition of portfolio optimization and its performance by applying genetic algorithms to models will be documented. This study posits a model that the asset management industry can achieve, with continuous and stable excess performance, low costs and high efficiency in the process of investment.
