  • Face recognition technology has lately attracted considerable attention because of its non-intrusiveness, usability and applicability. Related companies insist that their commercial products show the recognition rates more than 95% according to their self-testing. But, the rates cannot be admitted as official recognition rates. So, performance evaluation methods and tools are necessary to objectively measure the accuracy and performance of face recognition systems. In this paper, I propose a reference model for biometrics recognition evaluation tools, and implement an evaluation tool for the face recognition system based on the proposed reference model.

  • Purpose: The purpose of this study was to development and measure validity and reliability of evaluation tool for clinical nursing practice competency of Nursing students. Method: The participants in this study were 568 nurses who had worked for more than three years above in hospitals. A questionnaire of 79 items was administered to the nurses using a convenience sampling method. The data were collected from Sep. 12th, to Oct. 20th, 2004. Result: The derived outcome tool consisted of 6 factors of direct nursing actions and 6 factors of indirect nursing actions on the basis of 79 items. The 6 factors in direct nursing actions accounted for 76.84% of the variance and 6 factors in indirect nursing actions accounted for 79.68% of the variance on total scale. As a result of the item analysis, 79 items were selected and the internal consistency alpha coefficient was .9917. The value of Cronbach' alpha of direct nursing actions was .9640, indirect nursing actions was .9550. Conclusion: The results of this study show that useful application to the evaluation tool of clinical practice competency of Nursing students and further studies need to be done to verify clinical practice educational evaluation.

  • This study is to evaluate the tool performance in honing using diamond reamer and present grounds whether the localized products are sufficiently competitive comparing with the existing imported ones. The heads of the tool performance evaluation are roundness, roughness, tool life of the workpiece and so on. When evaluating the tool performance, cutting process is divided by three areas which are rough semi-finish and finish cut. cloning improves the accuracy such as boring and reaming after manufacturing the inside diameter, and finishing directly by honing is a recent trend. This honing is used greatly In hard cutting materials like cemented carbides and it is the CBN and diamond that is used in hard cutting materials. Both of them are expensive and most oi them are imported.

  • Purpose: Nutrition screening is vital to ensure patients are appropriately managed in hospital. In paediatrics there is currently no universally accepted nutrition screening tool. The Nutrition Evaluation Screening Tool (NEST) was developed as an easy to use and practical screening tool for hospitalised children. We aim to evaluate compliance of the NEST and assess agreement of the NEST with the already validated nutrition screening tools, Screening Tool for Risk on Nutritional Status and Growth (STRONGkids), Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP) and the Subjective Global Nutritional Assessment (SGNA) tool. Methods: Retrospective review of 102 patient episodes at the Evelina London Children's Hospital. Electronic records were used to assess NEST compliance and to complete the nutrition tools for each patient episode. Cohen's kappa was used to determine the level of agreement between each nutrition tool. Results: There was moderate agreement between the NEST and the two screening tools, STRONGkids (κ=0.472) and STAMP (κ=0.416) for patients on initial screening at admission. 87.2% of patient episodes were NEST compliant within 24 hours of admission to hospital. Conclusion: The moderate agreement between these two already validated screening tools enhances the NEST's validity as a paediatric screening tool. The NEST had the strongest correlation with the SGNA tool compared to other screening tools. The NEST is user friendly screening tool for hospitalised children.

  • The ultimate goal of health promotion programs is to improve the quality of life through promoting community health. Since the performance of health promotion programs are greatly affected by the quality of the planning and implementation process of the programs, the proper quality assessment of the program process is very important. According to existing literature, the tool for assessing the quality of the process and implementation as well as the outcome. However, no assessment tool for the quality of the process of health promotion programs has been developed in Korea. The purpose of the study is to develop a quality assessment tool for the process of health promotion programs being conducted at public health centers in Korea. The quality assessment tool developed in the study consists of the following four domains: strategic planning (14 items), program management (11 items), monitoring and evaluation (13 items), and resources and information (15 items). The strategic planning deals with the function of the planning staff and committees, community data analysis, the feasibility of the program, and the approach methods for attaining the goal of the program. The program management includes items on the qualification and power of the program staff. Monitoring and evaluation deals with the planning and education for monitoring, reporting and communication among program units, and feedback after monitoring. Finally, the resource and information covers the planning and activities for obtaining resources and information, community networking, beneficiaries' response, and consulting activity of the staff.

  • We are designed to solve cyber motion sickness, an important task that must be addressed for the growth of the virtual reality content industry. Not only the industry but also academia are paying a lot of attention. However, despite long interest and research on the phenomenon of cyber motion sickness, a solution has not been drawn. This is deeply related to the lack of tools that can effectively measure cyber motion sickness. Therefore, in this paper, prior studies on cyber motion sickness were analyzed to develop a tool that can effectively measure cyber motion sickness when users experience immersive virtual reality. The measurement method of cyber motion sickness used in previous studies, each characteristic and limitation, and common factors related to cyber motion sickness were analyzed. Each of the related factors was derived as sub-factors. Based on the analyzed contents, an effective cyber motion sickness measurement evaluation tool model in immersive virtual reality was presented. It is expected that the evaluation tool model can be used for the study of cyber motion sickness.
