Home appliance manufacturers have recently been trying to provide smart products capable of various Internet services. For example, one health care manufacturer provides a Wi-Fi-capable scale. Once users register their information with the manufacturer's server, their weight and body fat records are automatically uploaded to the server whenever they measure their weight. The users can then watch and check their weight log easily using a smart device, such as a smartphone or tablet. One of the biggest problems, however, is that the initial configuration of the appliances and the user registration process may be quite complicated to typical users who are unfamiliar with such IT devices. This paper proposes an autoconfiguration system structure and protocol for Internet-capable home appliances, which supports the initial configuration and remote maintenance service of the device with only little user effort. Manufacturers can develop their own information appliances and provide differentiated services using the proposed system and protocol.

Generally, the internet online game systems are divided into two parts, clients and servers. The clients provide a connection with game server to each user and communicate between them. And, the server controls all clients by the game rules fairly and manages database systems to maintain the user information. In this paper, we propose a configuration method for internet online game servers using distributed scheme. To apply this method, we divide game server into three sub-level parts again. First part of game server is login server to establish the connection between communication server and clients. Second part is communication server to connect between clients and main game server during playing the game. And last part is DBMS that performs database independently. Our proposed scheme suggests that the game server operates very stable because of decreasing of processing load by distributed scheme. So, our proposed server configuration applies to similar online game easily.

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.

This article describes an interference reduction scheme for Mobile WiMAX in an indoor environment. The feasibility of user deployed femtocells in the same frequency channel as an existing macro cell network is investigated. One of the important requirements for co-channel operation of femtocells such as auto-configuration and self optimization are discussed. In femtocell deployments, leakage of the pilot signal to the outside of a house can result of the higher number of mobility events caused by passing user of macrocell. This interference effect can be minimized by reducing the pilot power using proper scheme. This paper introduces existing auto-configuration method of power control and proposed interference reduction scheme using power control for Mobile WiMAX in an indoor environment.

Purpose: To establish guidelines for local public hospitals, the survey was conducted primarily on the current status of local public hospitals, focusing on the zone configuration and the spatial area of the operating department. Methods: 3 Methods have been used in this paper. 1) Analyzing drawings to derive the net floor area of each room. 2) A literature survey about composition of the zone by infection control. 3) Observation survey for user circulation analysis. Results: The operation department consists of the major, secondary, support and connected zones according to the user's actions. The spatial area composition ratio for each zone is major zone: 41.79%, secondary zone: 10.87%, support zone: 23.10%, and connected zone: 24.24%. Implications: This study is a basic research for guideline for the operation department in local public hospitals. In this study, zones configuration of the operation departments are classified in terms of user actions and room functions. In the future, it is required to establish criteria considering infection control and copper connection aspects.

버전 제어 시스템은 급속한 환경의 변화나 개발 환경이 복잡한 프로그래밍 환경에서 사용되고 있으며, 정의된 형상 규칙 정보를 정확하게 알지 못하는 경우나 미리 정의되지 않은 정보에 대해서는 형상 형성 정보 제공 문제가 발생한다. 본 논문에서는 사용자가 원하는 컴포넌트를 복합적으로 형상형성 제어 할 수 있는 라이브러리 시스템을 제안하고, 모델링하여 구현하였다. 제안한 형상형성 제어를 위해 사용되는 라이브러리는 확장 facet 분류를 응용하여 하부 표현 구조에 관계없이 라이브러리로부터 컴포넌트를 검색할 수 있도록 하였다. 이것은 본 논문에서 제안한 TreeSearch 클래스와 형상형성 제어 함수를 이용하여 관리된다. 본 논문의 라이브러리는 다른 언어와의 인터페이스를 통해 사용될 수 있으며, 사용자에 의해 facet이 확장되는 장점을 가진다.

A process control language is developed using function block configuration, to simplify software development for large scale process control systems, and to implement advanced control algorithms with ease. A function block parser and controller is implemented to be suitable for multi-loop control systems having hierachical structure. On-line change of controller parameter is possible, and inclusion of user defined function block is also possible. By adding plant model block, control performance can be checked in advance. Function blocks of the Smith Predicotor, auto-tuners are implemented to demonstrate usefulness of function block configuration.

For ease of use and access, web browsers are now being used to access and modify sensitive data and systems including critical control systems. Due to their computational capabilities and network connectivity, browsers are vulnerable to several types of attacks, even when fully updated. Browsers are also the main target of phishing attacks. Many browser attacks, including phishing, could be prevented or mitigated by using site-, user-, and device-specific security configurations. However, we discovered that all major browsers expose disparate security configuration procedures, option names, values, and semantics. This results in an extremely hard to secure web browsing ecosystem. We analyzed more than a 1000 browser security configuration options in three major browsers and found that only 13 configuration options had syntactic and semantic similarity, while 4 configuration options had semantic similarity, but not syntactic similarity. We: a) describe the results of our in-depth analysis of browser security configuration options; b) demonstrate the complexity of policy-based configuration of web browsers; c) describe a knowledge-based solution that would enable organizations to implement highly-granular and policy-level secure configurations for their information and operational technology browsing infrastructures at the enterprise scale; and d) argue for necessity of developing a common language and semantics for web browser configurations.

The purpose of this study is to suggest the modeling of ubiquitous environments according to the analysis of user's behaviors focused on the living area within the house. Recently, with appearing 'Ubiquitous environments', the applications of ubiquitous technologies on the our environment adopt a new paradigm. This new paradigm leads to the possibility of creating more intellectual dwelling environment according to user's behaviors. This paper suggests to change our dwelling by considering both engineering technology and the character of dwelling, because the house should provide causes humans with comfortability. Therefore, we need to understand user's behaviors in the dwelling, towards user friendly environment. Also, it very important for us to configure proper sensors and technologies by the priority based on user's behaviors. To sum up, this study is aimed to analyze user's behaviors and then, to suggest the guideline for users offering optimal ubiquitous environments.
