IMO has been proceeding in the maritime SQA for software quality is considered to be essential for the development of the introduction of the e-Navigation. In order to ensure software quality, follow the prescribed procedures throughout the software development project and create the output as a result of executing the respective steps. This paper is introduced a case for applying to maritime software development using the tool that is capable of real-time monitoring and automated documentation. Also, it is discussed the improvement of procedures for applying the expected effects and maritime SQA for thr tool utilization. The Development of customized tools for maritime SQA that is reflected an improved procedure for tool is the future goals.

With the diversified and enlarged softwares, the issue of software maintenance became more complex and difficult and consequently, the cost of software maintenance took up the highest portion in the software life cycle. We design Reverse Engineering Tool for software restructuring environment to object-oriented system. We design Rule - Based Reverse - Engineering using Class Information. We allow the maintainer to use interactive query by using Prolog language. We use similarity formula, which is based on relationship between variables and functions, in class extraction and restructuring method in order to extract most appropriate class. The visibility of the extracted class can be identified automatically. Also, we allow the maintainer to use query by using logical language. So We can help the practical maintenance. Therefore, The purpose of this paper is to suggest reverse engineering tool and evaluation reverse engineering tool.

Mild Cognitive Impairment(MCI) is a prior step to Alzheimer's Disease(AD). It is different from AD which is seriously affecting daily life. Particularly, the hippocampus could be charged a crucial function for forming memory. MCI has a high risk about progress to AD. Our investigated research for a relationship between hippocampus and AD has been studied. The measurement of hippocampus volumetric is one of the most commonly used method. The three dimensional reconstructed medical images could be passible to interpret and its examination in various aspects but the cost of brain research with the medical equipment is very high. In this study, 3D visualization was performed from a series of brain Magnetic Resonance Images(MRI) and we have designed and implemented a competitive software tool based on the open libraries of Visualization ToolKit(VTK). Consequently, our visualization software tool could be useful to various medical fields and specially prognosis and diagnosis for MCI patients.

Recently, for secure software development, static analysis tools have been used mostly to analyze the source code of the software and identify software weaknesses caused of vulnerabilities. In order to select the optimal static analysis tool, both weaknesses rules and analysis capabilities of the tool are important factors. Therefore, in this paper we propose the test codes developed for evaluating the rules and analysis capabilities of the tools. The test codes to involve 43 weaknesses such as SQL injection etc. can be used to evaluate the adequacy of the rules and analysis capabilities of the tools.

Tool interference is one of the most critical problems in sculptured surface machining. When machining cavities and concaves, the tool frequently overcuts the portions of the surface, which cause inaccuracy in machining. So tool interference-free paths must be generated for rough cutting more efficiently. In this paper a software using SSI(Surface/Surface intersection) algorithm is developed for eliminating tool interference which occurs in an offset surface in 3-dimensional free form surface modeling. this work consists of two stages : using the offset data, the intersection curves are rapidly checked by this algorithm at the first stage. CL(cutter location) data are obtained by deleting the loop section of intersected offset patches at the second stage. This algorithm can reduce the amount of memory required to store machining data and also easily check region which have the possibility of intersection. Also, This software is verified to be useful in machining a curved object on a DNC milling machine.
