Rib cutting is being used to many electronic components and small plastic products. In this study, comparison experiment on tool of flat type(2F) and single edge type(1F) was conducted. Results were as follows: Surface roughness and tool wear of straight cutting showed good results in tool with a straight structure of the Existing tool. Rib cutting of 7mm depth was shown 50% higher surface roughness of development tool than the existing tool. The cutting time varies depending on the shape of the rib. But it is three times faster compared to existing tool.

The R.O.K Army has developed and operated TM to maintain the operation of weapons systems since its establishment. As more modern weapons systems were developed, the more efficient operation was limited by a large quantity. As a countermeasure, the DAPA has operated the IETM using the KAIS TOOL since 2003. However, 16 years later, they were shunned by operators for software instability and other reasons. Based on the results of an operational test and evaluation team of the Army headquarters, the analysis results of software instability, limited compatibility and integration, limited real-time updates, etc. were analyzed. It was confirmed that KAIS development tools were urgently needed. Therefore, in order to solve this current problem for the Army IETM, the first phase of this paper focused on improving the IETM by maintaining the application present, the second of the Army Electronic Technology manual, phase going to propose improvement plans for operational test and evaluation by lining 11 elements of comprehensive logistics support with an electronic technology code.

Recently, a computer numerical control (CNC) machine is used widely for mold making in various industries. In the operation of a CNC machine, the production quality and safety of workers are becoming increasingly important as the product process increases. A variety of tool life prediction studies has been conducted to standardize the quality of production and improve reproducibility. When the tool life is predicted using the conventional tool life equation, there is a large error between the experimental result and result by the conventional tool life equation. In this paper, an algorithm that can predict the precise tool life was implemented using a genetic algorithm.

This is a methodological study that verifies the validity and reliability by translating and modifying the Korean version of Behavior Health Care Competency (BHCC) tool. This study verified the content validity, construct validity, and reliability of 230 nurses working in general hospitals. The BHCC tool was analyzed using a total of 4 factors and 16 items. The tool had a high level of reliability and validity. The BHCC is a measurement tool considering the mental health care of non-psychiatric nurses, and it has meaning in that it establishes basic material so non-psychiatric nurses can manage the patient's physical and potential psychiatric problems effectively.

Jungganbo is a writing method for the Korean traditional music. Since writing the Korean music needs to be done by hand and Chinese characters are used, only an expert musician might handle Jungganbo. In this paper, an authoring software tool for Jungganbo is introduced. It is useful for anybody who wants to compose the Korean tradition music with a computer. This tool also enables to standardize writing techniques of Jungganbo because a musical score was done by hands without using an authoring tool. In addition, this authoring tool can be easily used since its environment is very similar to other windows-based programs such as Ms-word and Hwp. Not only the beginners but also the experts can use this authoring tool for their Korean traditional music writing easily.

This paper proposes a development tool to efficiently develop node software for various operating system platforms in a sensor network. The proposed tool consisted of several modules, such as writing graphical model diagram, PIM and PSM design, code generation, and deployment file generation. Through the proposed tool, the users can graphically draw a sensor network model and design the PIM and PSM of the node software by setting the values of the predefined attributes. The source code of the node software is generated automatically from the PSM using the code templates of the target platform. The deployment files for installing node software on each node are generated automatically. The proposed tool helps the users to develop node software easily for a range of target platforms, even though they do not have details of the low-level information for a sensor network.

A tool was developed in this research for automation of one-dimensional finite element analysis (1D FEA) for design of a machine tool spindle system composed mainly of a shaft and bearings. As it is based on object-oriented programing, it uses the objects of a CAD system. It requires minimum data to be input to define the spindle system such as shaft cross-sections and bearing stiffness. Then, it automatically generates the geometric model based on the data and then, converts it into the FE model of 1D beams and springs. The graphic user interfaces developed allow a user to interact with the tool. This tool can be applied to identification of a near optimal design of the spindle system in minimum time and efforts by automating the FEA process with numerous design changes.
