With the growth and maturation of IT industry, the necessity of audit about development, maintenance and management of high-quality information system is gradually increasing. In addition, the necessity of inner auditing system, which could totally verify and evaluate the effectiveness of project according to the characteristics of organization conducting information-oriented business, also being proposed. Government offices including Korea Institute of Science and Technology(KISTI) collectively controlling nationwide science-technology related information have no guiding principle or organization within themselves even though performing information-oriented businesses are becoming more bigger and complicated. In this paper, we propose scheme for devising framework, which can audit construction and operation of knowledge information, check list and guideline. In addition, we present concrete ways for adapting these schemes to institutes which manage science-technology knowledge information. Audit framework consists of points of time in audit, audit domain and audit criterion. Points of time in audit are defined as three phases as followings: pre-audit, in-progress audit and post-audit. Audit domain includes 16 detail audit domains and especially we set 11 check items and 40 detail investigation items for database implementation business. We expect that management level of science-technology implementation business of organizations using this research result will increase and they could offer high-quality information service.

This paper analyzes the tree expansion for multiple-input multiple-output (MIMO) detection in the viewpoint of hardware implementation. The tree expansion is to calculate path metrics of child nodes performed in every visit to a node while traversing the detection tree. Accordingly, the tree-expansion unit (TEU), which is responsible for such a task, has been an essential component in a MIMO detector. Despite the paramount importance, the analyses on the TEUs in the literature are not thorough enough. Accordingly, we further investigate the hardware complexity of the TEUs to suggest a guideline for selection. In this paper, we focus on a pair of major ways to implement the TEU: 1) a full parallel realization; 2) a transformation of the formulae followed by common subexpression elimination (CSE). For a logical comparison, the numbers of multipliers and adders are first enumerated. To evaluate them in a more practical manner, the TEUs are implemented in a 65-nm CMOS process, and their propagation delays, gate counts, and power consumptions were measured explicitly. Considering the target specification of a MIMO system and the implementation results comprehensively, one can choose which architecture to adopt in realizing a detector.

This study develops a business ethics education program and verifies its effects through the implementation of a program for fashion companies. Questionnaires obtained from 161 fashion companies were submitted for an analysis of the education needs of business ethics components using the Borich's Needs Assessments Model and the Locus for Focus model. The business ethics component in the highest rank of the education need was 'promoting social contribution (PSC)'. An education program of PSC was developed based on the problem-based learning method and was implemented for 180 minutes on the CEOs or managerial board members of eleven fashion companies. Education participants showed an improvement in the perceptions of the business ethics component after the education seminar. The self-efficacy and the education effect perceived by participants were maintained 70 days after education. This study is meaningful to gain an empirical evidence of the positive effect of business ethics education implemented on the practitioners of fashion companies. The results will provide a knowledge base and a guideline for business ethics education in the fashion industry.

Purpose: This study was designed to develop, to implement and evaluate a fever management nursing protocol for adult patients. Methods: This study was conducted through seven steps following both the guideline development procedures of the Scottish Intercollegiate Guidelines Network and the Model of the Asan Medical Center Evidence-Based Practice, as follows: 1) identifying the clinical needs and composition of the protocol development group; 2) identifying and evaluating the evidence; 3) assessing the level of evidence and grading recommendations; 4) forming a protocol; 5) evaluating the protocol using an expert group validity test and identifying barriers to its implementation; 6) protocol development; and 7) evaluation of practical improvement measures following implementation of the protocol. Results: The evidence-based protocol for fever management in adult patients was completed and includes five domains and 15 items. The protocol had good content validity (CVI=.90) and nursing practice could be improved after implementation of the protocol. Conclusion: This nursing protocol can be used as a guide for nursing in febrile adult patients. We recommend that further guidelines be updated in an interdisciplinary manner in order to foster local adaptation of the best clinical practices.

Purpose: Researchers found that blocks of evidence-based practice (EBP) implementation lacked opportunities for EBP education. The study found that physical therapists had negative views of research as well as their roles in EBP, lacked confidence in EBP, and had limited access to web-based materials. The purpose of this study was to highlight the importance of information research technology for efficient EBP in a clinical environment. Methods: The web-based information research technologies that should be used for sustainable EBP include: the clinical practice guideline (CPG) and PubMed's My NCBI service. Journal mailing services and other academic information sources should also be used to gather information from RSS feeds. An EBP library or archive must be created. A site that provides EBP-specific information is also needed. Results: We should usually do EBP. Practitioners must learn and use information technologies that will help them improve their EBP skills. Conclusion: Facilitating EBP implementation and building an EBP system require related education as well as a practical work environment and equipment. However, the highest priority is individual efforts and trial. Information technology will complement the lack of time. It is important to use information research technology to overcome real obstacles. Lasting EBP must use a number of web-based information research technologies to overcome the practical challenges encountered in EBP implementation.

The endowment and concession has been put to practical use for the relocation projects of military Facilities. Yet, in terms of the project implementation, delay of a great deal of the projects is occurring due to related regulations and standards, as well as a lack of mutual understanding between project implementers and military units. This study analyzes the risk factors by identifying and prioritizing the potential risk factors at each stage of project implementation such as the issues that limit project characteristics and implementation. Among the derived risk factors, request exceeding facility standards in the licensing and design phases, opposition to troop relocation in the project approval phase, design change during construction phase in the construction and completion phases, dissenting opinions on endowed/conceded property in the property disposal phase and absence of facility standards in the MOA conclusion phase were found to be the main object of consideration in risk management. This study is expected to provide project managers with a guideline for effectively pursuing the projects, as it provides prioritization and optimization of risk management.
