  • Reliability is absolutely necessary in most recent mission critical systems which usually utilize the Ethernet based computer networks. A typical way to increase system reliability is to equip the fault tolerant Ethernet. In this paper we try to formulate the fault tolerant dual Ethernet concept and presents a comparison of its implementation approaches. Two types of dual Ethernet configuration are analyzed; the divided and the connected. Then the characteristics of three current implementation approaches which are the hardware based, the software based, and the recently proposed hybrid approach are compared. The results show that the hardware based or the hybrid approaches can be a better solution for the real time mission critical systems. Also for the systems which require the use of Commercial-Off-The-Shelf (COTS) hardware for fault tolerant Ethernet the possible choice is the software based or the hybrid approach.

  • This paper describes the origins, evolution of Quality Function Deployment and its transfer to the West. Following a comprehensive review of the literature and how QFD has been defined, and applied, the paper analyses the critical factors which impinge on QFD implementation success. A discussion which covers the enabling criteria found to be inherent in Japanese applications is contrasted with the Western approaches documented hitherto. In particular the Company Wide Quality Control (CWQC) approach in Japan versus the emerging concept of Total Quality Management and their impact on QFD implementation. A critical analysis of the main differences isolated from the review of the literature and which characterise the Japanese method of QFD implementation which is leading, and The Western approaches which appear to be lagging is included in the paper, together with some useful conclusions:

  • In recent decades, significant effort has led to risk-informed improvements to regulation. Performance-based approaches also promise significant gains in efficiency (level of safety versus effort). However, significant work remains to be done before performance-based approaches realize their full potential in regulation of nuclear power plants. This paper reviews key concepts related to performance-based regulation, discusses some applications of performance-based approaches, and identifies issues that still need to be addressed. Realistic, experience-based models of licensee performance are still lacking; this makes it difficult to assess the prospective effectiveness of any given regulatory approach, in light of the performance issues that it will actually face. Also, while 'compliance' is an intuitively straightforward concept to apply within a prescriptive implementation, its analog in a performance-based approach remains unclear. An overarching theme of the paper is that formal methods of decision analysis are very helpful in developing appropriate regulatory approaches, especially performance-based ones; this theme is illustrated at several points.

  • White-box cryptography is an implementation technique in order to protect secret keys of cryptographic algorithms in the white-box attack model, which is the setting that an adversary has full access to the implementation of the cryptographic algorithm and full control over their execution. This concept was introduced in 2002 by Chow et al., and since then, there have been many proposals for secure implementations. While there have been many approaches to construct a secure white-box implementation for the ciphers with SPN structures, there was no notable result about the white-box implementation for the block ciphers with Feistel structure after white-box DES implementation was broken. In this paper, we propose a secure white-box implementation for a block cipher SEED with Feistel structure, which can prevent the previous known attacks for white-box implementations. Our proposal is simple and practical: it is performed by only 3,376 table lookups during each execution and the total size of tables is 762.5 KB.

  • Essences, needs and features of formation of national innovative development model of Kazakhstan are proved on the basis of analysis of various research approaches to realization of the modernization that exist in the world economic theory. For studying the problems of innovative development of the country, there was a need for the formulation of a number of definitions, disclosure of their contents, changing the approaches to reform, as well as adjusting their targets. In the article the general scientific research methods used dialectic, abstraction, systemic and situational approach, empirical and theoretical and analytical methods, and logic modeling. The proposed approach to the implementation of innovative development based on the use of evolutionary and institutional approaches to the study of the problems of implementing an effective innovation policy. This approach is intended to contribute to the development of a forward strategy of modernization, innovative development and higher competitiveness of the national economy. The study proved the causes and features of the implementation of innovative development model in Kazakhstan.

  • In 1990s, many organizations recognized the ERR system as a key enabler of business strategic accomplishment and it can improve productivity and efficiency of organizations by integrating and managing enterprise resources. These organizations tried to implement the ERP system to hold the competitive advantage. And the ERP system leads to business process reengineering. So it is important to consider both organizational environmental characters and change management in the ERP implementation process. This study is examined in detail about organizational environmental characters and change management in the ERP implementation process, seeks how the difference of these factors related to the ERP success. The sampled companies implemented the ERP system by using the different ERP implementation approaches. This study provides that the ERP implementation approach differs from organizational environmental characters, and change management tactics are different according to the ERP implementation approaches. But, some change management factors are important regardless of the ERP implementation approaches. This study also provides the effects on EPR performance through the change management. The study is of service to the organizations implementing ERP and provides practical contribution for managing organizational changes.

  • Joint probabilistic data association filter(JPDAF) for multi-target tracking was developed for real-time implementation, while it abandoned an algorithm for track initiation. In this paper, we propose three features for track initiation that can be adapted to the JPDA filter. In addition, with the proposed approaches, the performance of track maintenance is evaluated in the case of tracks being near. To eliminate the abundant false tracks, we exploit the simple method using the state error covariances. Simulations are performed to demonstrate the efficiency of the proposed approaches.

  • Getting evidence in to practice tends to focus on strategies, theories and studies that aim to close the gap between research knowledge and clinical practice. The evidence to practice gap is more about systems than individual clinician decision making. The absence of evidence for administration and management in the organization of healthcare is persistent. Teaching nurses and providing evidence as the solution to evidence-based healthcare is no longer axiomatic. Previous studies have concluded that unit level strategies integrate multi-professional teams with organizational needs and priorities. This 'best fit' approach that characterizes how healthcare is structured and delivered. The published literature shows that increased readiness for change is aligned with integrated approaches informed by conceptual models. The Joanna Briggs Collaboration is the largest global collaboration to integrate evidence within a theory informed model that brings together academic centres, hospitals and health systems for evidence synthesis, transfer and implementation. The best approaches to implementation are tailored to local culture and context, benchmark against international evidence, combine a theory informed model and stakeholder perspectives to improve the structure and processes of health care policy and practice.

  • As many organizations have adopted and implemented ERP systems, concerns about ERP performance also have increased. Former researches studied the ERP implementation of general large or medium size enterprises but there are not enough studies on ERP systems of a specific industry domain. In this paper, we introduce a case study on ERP adoption methodology of global leading company 'D' in shipbuilding and marine engineering industry. We examined ERP implementation background, method and scope and evaluated ERP performance in perspective of both quantitative and qualitative approaches. Quantitative research usually examines ERP performance based on financial statements and qualitative study typically examines organization change or improvement. As a result, ERP implementation in shipbuilding and marine industry can improve quantitative aspects such as cost, human resource and organization performance. As qualitative analysis, business process and tools can be unified and management transparency can be improved by ERP implementation. The result of this paper will be useful guideline for organizations which are considering ERP systems.
