Purpose: The purpose of the study was to identify characteristics of nursing and caring concepts measured by nursing competencies or caring behaviors tools for general nurses working in acute care hospitals. Methods: Five major nursing literature databases were used to identify the relevant tools. The study included 19 nursing competencies tools with a total of 843 measurement items and 12 caring behaviors tools with 334 items. According to the International Council of Nurses (ICN)'s Competencies Framework and 8Cs suggested by Roach (1987) and Pusari (1998), the measurement items were classified by two researchers independently first and in agreement finally. Results: Competency of 'key principles of care' including sub-areas of the ICN Framework was most commonly found: on average 49.3% of nursing competencies items and 91.9% of caring behaviors items. 97.0% of the caring behaviors items were classified into one of six Cs: competence (27.5%), confidence (21.3%), compassion (17.1%), commitment (16.5%), communication (9.9%), or conscience (4.8%). Conclusion: Nursing competencies tools were more likely to measure 'what to do' focusing on tasks, while caring behaviors tools were to measure 'how to do' focusing on nurses' attitudes or values. Nursing practices should be evaluated with both nursing competencies and caring behaviors tools, considering that nursing and caring were differently conceptualized in the quantitative tools.

The design process of machine tools is regarded as a sequential, discrete, and inefficient works as it requires various kinds of design tools and many working hours. This paper describes an integrated design system embedding a design methodology that can support efficiently and systematically the conceptual structural design of machine tools. The system is a knowledge-based design system and has four machine-tool-specific functional modules including configuration design, configuration analysis, structure design, and structural analysis support module. Through the configuration design and analysis module, a machine configuration appropriate for design requirements is selected, and then the arrangement of ribs fer each structural part is decided in the structure design module. Also, the structural analysis support module is used to evaluate design result by utilizing structural analysis software, ANSYS. The system is applied to design of a tapping machine, and shows that the machine structure can be designed fast and conveniently by processing each design step interactively.

Recently, case presentations using AI functions such as ChatGPT are increasing in many industrial fields. As AI-based results emerge even in the areas of images and videos, traditional animation production tools are in need of significant changes. Unreal Engine is the tool that adapts most quickly to these changes, proposing a new animation production workflow by integrating tools such as Metahuman and Marvelous Designer. Working with realistic metahumans allows for the production of realistic and natural movements, such as those captured through motion capture data. Implementing this approach presents many challenges for production tools that adhere to traditional methods. In this study, we investigated the differences between the cell animation workflow and the computer graphics animation production workflow. We compared and analyzed whether these differences could be reduced by creating sample movements using character rigs in Maya and Cascadeur tools. Our results showed that a similar cell animation workflow could be constructed using the Cascadeur tool. To improve the accuracy of our conclusions, we created large, action-packed short animations to demonstrate and validate our findings.

A reliability evaluation or prediction can be defined as MTBF which stands for mean time between failures (Exclusively for repairable failures). Spindle system has huge effect on performance of machine tools and working quality as well as is required of high reliability. Especially, it takes great importance in producing automobiles which includes a large number of working processes. However, it is unusually difficult to predict reliability because there are lack of data and research about reliability of spindle system. Standards and methods of examinations for reliability evaluation of machine tools are scarce at local and abroad as well. Therefore, this research is meant to improve the reliability of spindle system before mass produced with developing standards of reliability and methods of examinations through FMEA to assess reliability of spindle system in prototype stages of developing high speed spindle system of machining center.
