The importance of software is getting high in development of the digital device (digital camcoder, digital camera, mp3 player, ....). And because the sire of software becomes larger and complicated, the necessity of software configuration management (to solves a software crisis) is increased. The general software configuration management system shows lack of the property and features of software development environment for image processing algorithm due to its wide range to be covered. Image processing algorithm development environment has properties like repetitive analysis and simulation using visual programming environment where, beside support of elementary development functions. component(or library) can be combined and tested interactively. Moreover, the method to look fast and effectively for component having similar function is required. In this paper, we present the system which supports the software configuration management method for a simulation tool and the property in the visual programming environment. And we relate our system to real simulation tool so as to check its ability as the software configuration management system for image processing algorithm development environment.

In order to apply a static fault-tree (FT) method to a system or a plant whose configuration changes dynamically, condition gates and a post processing method are used to effectively accommodate these changes. An operator's performance change, which can be caused by these configuration changes, should also be considered to assess the risk to a plant in a more realistic manner. This study aims to develop an integrated framework to accommodate various configuration changes and their effect on an operator’s performance by using the FT model. We applied a condition-based human reliability assessment (CBHRA) method to consider various conditions endured by an operator. That is, we integrated the CBHRA method with the conventional post processing method for modeling the system configuration changes. The effect of the condition monitoring systems installed in a plant is also considered. In this study, we show an example application of the integrated framework to a probabilistic safety assessment for the shutdown phase of a nuclear power plant.

The Internet Key Exchange (IKE) protocol is most widely used as a security key exchange protocol on the Internet. Security policies used by the IKE protocol must be configured in advance, however the complex options and manual settings cause inconvenience. This paper proposes an automatic configuration method for the IKE protocol based on X.509 certificate. Security policies are embedded in the certificate, read, and added into the IKE configuration file by a negotiation assistant module in order to achieve automatic IKE configuration. Our proposed method reduces the complexity of configuration process and improves the adaptability of the IKE protocol.

Log analysis and monitoring have a significant importance in most of the systems. Log management has core importance in applications like distributed applications, cloud based applications, and applications designed for big data. These applications produce a large number of log files which contain essential information. This information can be used for log analytics to understand the relevant patterns from varying log data. However, they need some tools for the purpose of parsing, storing, and visualizing log informations. "Elasticsearch, Logstash, and Kibana"(ELK Stack) is one of the most popular analyzing tools for log management. For the ingestion of log files configuration files have a key importance, as they cover all the services needed to input, process, and output the log files. However, creating configuration files is sometimes very complicated and time consuming in many applications as it requires domain expertise and manual creation. In this paper, an auto configuration module for Logstash is proposed which aims to auto generate the configuration files for Logstash. The primary purpose of this paper is to provide a mechanism, which can be used to auto generate the configuration files for corresponding log files in less time. The proposed module aims to provide an overall efficiency in the log management system.

This paper presents the configuration of simulator for the functional test of TCMS on developing. This simulator is composed of three cabinets. There is equipped the TCMS system which have the same configuration of 1 train(SMG Line 7＆8) on the two cabinets. And there are equipped VME PC, VME CPU Board and I/F modules on the rest cabinet. This simulator has tow parts, which are user I/F part and Real-time signal processing part. We programed user I/F part with Visual C++ to support GUI function, and signal processing part with RTOS to support Real-Time signal processing. This simulator can produce all the signal and data for the TCMS functional testing.

In this paper, an algorithm to make a configuration system for managing the I/O device of programmable logic controller(PLC) is proposed. Parallel processing architecture is used to deal with a number of I/O devices. From that architecture, a contention problem between processors can arise. To resolve this problem, the configuration system that contains informations about I/O devices is introduced. This configuration system is used to check the contention between processors in the I/O device and also used in program execution.

In this paper, we design implement an Object-Oriented Graphic System Configuration Editor for Access Control Systems. 'Visual Builder', with such functions as graphic drawing, system configuration, graphic management, processing of user input through graphics. Visual Builder is designed to be well separated from and independent of S/W parts closely coupled with the underlying H/W and thus to improve its reusability and maintainability.

In this paper, we present a method for smartphone users to have a better user experience when playing 3D mobile games using the gyro sensor. We designed the rotation of the virtual camera in the game world to be proportional to the real-world's rotation. We have also made the sensitivity configuration possible for users to manipulate.
