Currently a KTX train of 20-car formation is 388m long and carries 931 passengers including one captain and three crews which is quite a few to cover the lengthy service area and many customers. On the other hand, if a passenger wants to talk to an attendant, he has to wait for an attendant passing by his/her seat or walk to an intercom which is placed at every other car. Any of these choices is inconvenient. So, in this paper, we presented a system design for developing an audio/visual communication system for a passenger and an attendant. The system was analyzed and designed according to the Object-Oriented methodology with UML (Unified Modeling Language). Based on a problem statement, a Use-case Diagram, Sequence Diagrams, Class Diagram, State Charts, collaboration Diagram were generated. The design will be used in system implementation to a HEMU-400X test train and to be tested.

Purpose: This study was intended to measure the knowledge and attitudes of nurses working in a psychiatric ward regarding the subject of pain. Methods: In this descriptive study, data were collected in psychiatric wards(or hospitals) located in the Kyungnam and Kyungpook area from December 2013 to January 2014, using a modified version of the McCaffrey and Pasero Clinical Manual Survey Regarding Pain. The content of the survey follows a logical progression from common pain management problems through mechanisms of pain, assessment and pharmacology. Results: The average score of knowledge regarding pain was roughly $21.59{\pm}2.93$ among the 181 participants. The nurses selected Tylenol as the preferred choice (81.2%). Seventy-one percent of respondents didn't use Pain Intensity Instruments during the pain assessment. The subjects preferred the Numerical Rating Scale rather than Visual Analogue Scales. Pharmacology questions were the least likely to be answered correctly. No specific correlations were found between score and demographic variables of age and experience. No specific correlation between score and educational level was noted. Conclusion: Nurses require ongoing education on pain management, particularly regarding pharmaceutical agents.

This study aims to analyze how the color of Korean traditional architecture affects its plasticity. The researcher took (our distant and near photographs of each representative building of each use, measured the colors, and analyzed these using the color perception theory. The results are summarized as follows: 1. When perceiving the entire plasticity of a building, the color of Korean traditional architecture reduces the heavy feeling that may be brought about by the roof's weight, but stresses the solidity of the pillars. This color perception effect displays the visual stability and balanced plastic beauty of the building's facade. 2. When looking at a building up close, the building's color emphasizes the solidity of the major materials used to construct it through a contrast effect, and highlights the characteristics of each building, such as the dignity of its seal engraving, its magnificence, its simplicity, etc. 3. The color of Korean traditional architecture is a major factor that expresses plastic language as it displays topographical level differences and intercepts or opens view through the artificial division of space, etc., according to the building's use.

It is necessary to construct an effective regional information system in facing the incoming information intensive society. Many local government in Korea began to recognize a need for constructing a GIS(Geographic Information System) and they are planning to construct GIS´s to improve their administrative efficiency. However, ti requires high-priced hardware, software, and an experienced operator to sue a GIS effectively. The purpose of this study is to develop the GIS program which can be sued with ease by common users. By developing a GIS functioned program using a coordinate recognition module by application of geo-spatial data, and a digital map which is already made, this program can be used efficiently only by only inputting attributes without high-priced hardware and software, and can be utilized easily to every purposes of work with geo-spatial data and attributes. MapObjects, mapping and GIS component, was employed to use geo-spatial data, and Access 97 from Microsoft to manage and attributes database. Visual Basic, objected-oriented language, was used to develop an application program. Results of this study were applied to constructing the Information system of Kanwon National University. This program could be used for various purposed by common users without additional hardware and software.

In this paper, autonomous information exchange methodology is studied between IEDs using SOAP protocol based on XML and PtP communication to archive the safety and reliability of large-scale system operation. The SOAP protocol has the advantages in the independency Problem for operating systems, using language, platforms and the security problem because it is XML-based RPC protocol. Inference-based solution of the IED is designed as rule-based solution so that the IED internal status, the system status or the faulted zone can be inferred autonomously using the internal data as well as information data obtained from free information exchange among other IEDS, Also, it is designed so that the inference results and the operation information are transmitted to the above SCADA system, and determined autonomously whether the commands from the SCADA are executed or not. Finally, The inference-based solution of IED and information exchange system among IEDS is implemented using MS Visual C++ MFC, MS SOAP and MS XML. Availability and accuracy of the proposed methodology and the design is verified from diversity simulation reviews for typical distribution substation.

Digital images are easily corrupted by noise during the data transmission, data capture and data processing. A technical method of noise analyzing and adaptive filtering for reducing of quantum noise in medical radio-fluoroscopy images is presented. By adjusting the characteristics of the filter according to local statistics around each pixel of the image as moving windowing, it is possible to suppress noise sufficiently while preserve edge and other significant information required in diagnosis. We proposed adaptive weighed median(AWM) filters based on local statistics. We showed two ways of realizing the AWM filters. One is a simple type of AWM filter, which is constructed by Homogeneous factor(HF). Homogeneous factor(HF) from the noise models that enables the filter to recognize the local structures of the image is introduced, and an algorithm for determining the HF fitted to the diagnostic systems with various inner statistical properties is proposed. We show by the experimented that the performances of proposed method is superior to these of other filters and models in preserving small details and suppressing the noise at homogeneous region. The proposed algorithms were implemented by Visual C++ language on a IBM-PC Pentium 550 for testing purposes and the effects and results of the filter in the various levels of noise and images were proposed by comparing the values of NMSE(normalized mean square error) with the value of the other existing filtering methods.

Recently the substation automation is actively researched at each country. Since the substation automation is an integrated system that consist of electrical, electronic and computer technologies, performance evaluation is very important to inspect the developed system's applicable possibility for real power system. Most studies are verified using computer simulation, because it is hard to apply them to real power systems. Therefore development of a substation simulator is necessary for the performance evaluation of many application systems such as operator aid system. This paper introduces a substation simulator. An intelligent fault diagnosis and restorative control expert system is also introduced UDP/IP is applied as a protocol for data transport between expert system and SC(station computer). As to the Graphic User Interface, C++ Language and Visual Basic is used in the Windows NT operating system together with four Pentium II systems.

Various sensor devices has been developed as the wireless Internet and IoT technology are widely used. Recently, open source hardware has evolved for providing various services in IoT environments. However, in comparison to the development of the open source hardware, the development of human resources is missing. In order to solve such a phenomenon, in this paper, we propose a software framework for the embedded software development in open source hardware. The proposed framework provides a fast and intuitive development environment by using the visual programming language and providing fast feedbacks to developers. In addition, we discuss the strengths and weaknesses of the proposed scheme based on the implement on a real board.

In this paper, we introduce the development of a LOTOS-based tool, supporting formal methods, called ForTIA (A Formalism for Telecommunication and Information Systems). By using LOTOS, an ISO standard formal specification language, the user requirements and system models can be abstracted and represented formally. Therefore, the system can be validated and verified on the specifications, before implementations. ForTIA supports light-weight formal methods based on validation to be used in real industry. Key functions of ForTIA are simulation and C++ code generation. In simulation, tree based visual validation mechanism is provided and in code generation, the full C++ source code is generated to be used for system implementations.
