Control systems of compressed gas supply facility are responsible for storing and supplying compressed gases required for launch complex qualification test and launch operation. Most of the facilities that make up the launch complex require compressed gas for their operation. Therefore, such control systems should be developed and verified earlier rather than the other systems that constitute the launch complex. Each verification for hardware and software is performed separately. In particular, software verification of control algorithms loaded on the controller takes a lot of time and man power during the development period of the control system. Thus, specific test procedures and methods should be prepared in advance for efficient development. This paper introduces the configuration of a compressed gas supply facility and its control system with the verification procedure and results of major algorithms.

The newly updated Rail Safety Act is required to build a comprehensive railway safety management system with corresponding accreditation regulations for the purpose of safe railway operations. However, such efforts would not be enough to achieve a successful safety-performance solely without being in place of an appropriate level of safety cultures in an organization. No research was taken place to propose a safety culture maturity model and its estimate procedures in Korean railway industries. The research reviews a variety of safety maturity models applied in many other industries and the process of conducting surveys in order to propose a framework of railway safety maturity estimates, with a set of railway safety elements. This research is expected to contribute in diagnosing weak areas and finding their appropriate treatment, along with in placing the railway safety certificate program from 2014.

An in-cabinet response spectrum should be generated to perform the seismic qualification of devices and instruments mounted inside safety-related electrical equipment installed in nuclear power plants. The response spectrum is available by obtaining accurate seismic responses at the device mounting location of the cabinet. The dynamic behavior of most of electrical equipment may not be easily analyzed due to their complex mass and stiffness distributions. Considering these facts, this study proposes a procedure to estimate the seismic responses of a structure by a combination of a test and subsequent analysis. This technique firstly constructs the modal equations of the structure by using the experiment modal parameters obtained from the impact test. Then the seismic responses of the structure may be calculated by a mode superposition method. A simple steel frame structure was fabricated as a specimen for the validation of the proposed method. The seismic responses of the specimen were estimated by using the proposed technique and compared with the measurements obtained from the shaking table tests. The study results show that it is possible to accurately estimate the seismic response of the structure by using the experimental modal parameters obtained from the impact test.

Risk management is an important element for successful management of overseas construction projects. This study reports a case study in which we proposed a risk management planning and procedure for plant construction which can be applied throughout the project life cycle. We analyzed the risk management practices of Korean construction companies by applying the concept of the PRINCE2 method developed in the UK, and proposed a risk management planning and procedure with organizational structure and working process. The suggested risk management planning and procedure was applied to an overseas plant construction project, and produced good results. It is believed that the procedure suggested here can also be aplied to other companies to enhance the competency in the global construction market.

This study is to present cooperative instructional concept framework for the library-based instruction of teacher-librarians, based on 'Information and the Library' curriculum and instructional design procedure. The development of cooperative instructional units has been initiated in the school libraries, but the research based on instructional theories, including instructional design, is lacking. In this aspect, instructional theories and methodologies for the cooperative instruction of teacher-librarians are important. The cooperative instructional units for teacher-librarians should be developed by 'Information and the Library' curriculum and instructional design procedures. The objectives of the curriculum emphasize information use process based on information task. This study is to present cooperative instructional concept framework, and to help teacher-librarians develop specific cooperative instructional units based on the framework.

As the game industry is blooming, the generation of contents is far behind the consumption of contents. With this reason, it is necessary to afford the game contents considering level of game player's skill. In order to effectively solve this problem, Procedural Content Generation(PCG) using Artificial Intelligence(AI) is one of the plausible options. This paper proposes the procedural method to generate various monsters considering level of player's skill using genetic algorithm. One gene consists of the properties of a monster and one genome consists of genes for various monsters. A generated monster is evaluated by battle simulation with a player and then goes through selection and crossover steps. Using our proposed scheme, players adaptive monsters are generated procedurally based on genetic algorithm and the variety of monsters which are generated with different number of genome is compared.

In this study, a seismic performance evaluation of unreinforced masonry buildings was conducted based on a revised draft of the outline of the seismic performance evaluation of existing buildings. The procedure of the performance evaluation is composed of three-steps, which are a preliminary evaluation, a first-level detailed evaluation, and a second-level detailed evaluation, where evaluation is conservatively conducted in the beginning and then more detailed evaluations are gradually conducted. For the study, ten two-story unreinforced masonry buildings were selected and evaluated using the three-step evaluation. The result showed that the performance levels between the preliminary and the first-level detailed evaluations were reversed, which is different from the intent of the procedure. Therefore, in the near future, the problems in each evaluation step that are presented in the results of this study need to be refined.

To boost the IPTV industry, it has being considered to provide terminal portability from one service provider to another for users. If the terminal portability is guaranteed, then a service user can purchase an IPTV terminal in a market and select an IPTV service provider. For this, the IPTV terminal should process a series of pre-configuration, so called provisioning procedure. Telecommunications Technology Association (TTA) established the standard of IPTV terminal provisioning procedure, TTAK.KO-08.0026. In this paper, we explain the revised standard TTAK.KO-08.0026/R2, and introduce the architecture, functions, operating procedures and parameters of the IPTV terminal provisioning system that we implemented based on it. Finally, we discuss the future issues of the standard of the IPTV terminal provisioning procedure.

Due to the development of Internet, number of online documents and the amount of web services are increasing dramatically. However, there are several procedures required, before you actually find what you were looking for. These procedures are necessary to Internet users, but it takes time to search. As a method to systematize and simplify this repetitive job, this paper suggests a DotQuery based interactive search agent. This agent enables a user to search, from his computer, a plenty of information through the DotQuery service. which includes natural languages. and it executes several procedures required instead. This agent also functions as a plug-in service within general web browsers such as Internet Explorer and decodes the DotQuery service. Then it analyzes the DotQuery from a user through its own program and acquires service results through multiple browsers of its own.
