This paper presents a simple sensor network consists of a group of sensors, RF components, and microprocessors, to perform a distributed sensing and information transmission using wireless links. In the proposed sensor network, though each sensor node has a limited capability and a simple signal-processing engine, a group of sensor nodes can perform a various tasks through coordinated information sharing and wireless communication in a large working area. Using the capability of self-localization and tracking, we show the sensor network can be applied to localization and navigation of mobile robot in which the robot has to be coordinated effectively to perform given task in real time.

Purpose: The objective of the present study was to develop and evaluate a legal communicable diseases (LCDs) electronic system for infection control. Method: The system was developed through the procedure of analysis, design, implementation, application and evaluation, and was applied within an OCS (order communication system). Results: As indicated by the main menu, the present system is composed of an improved perception system for enhancing perception of LCDs, LCDs identification system, and improved efficiency in the report system. Detailed items included in the main menu are introduction and log-in screen, pop-up window for checking the outbreaks of LCDs, decision making icon, electronic signature icon, electronic report form, email system, etc. The total number of reports was greater after the application of the system (n=99) than before (n=80), and the adequacy of report time was statistically significantly higher after application of the system (P<0.05) Conclusion: The present system suggests a new method for LCDs report and infection control, and is expected to be adopted by other medical institutions in the future.

Analyze semantic of files recorded in the user's computer file system based on C++ program language which pursue modularization program and object-oriented programming language. And this refers to it, it design that clustering semantic of filename with thesaurus for user convenience. WTPM makes User Write Files into Cluster with thesaurus semantic structure and reserved words. WTPM process has designed for Icon file's display Mashup structure and implemented by automation algorithm of classification.

This paper studies on the visibility of dashboard in forklift. As part of the real setting devised for this study, 1. Important evaluation by males experience in forklift driving, 2. Icon cognition experiment, 3. Gage cognition experiment, subjects were asked to estimate the important evaluation, sketched to icon and gage position on the screen. Subjective evaluations were carried out by semantic differential method, sketch method, sketch method, then analyzed by consistency test, frequency rate and T-test. I gather the results concerning the relationship between consistent answers and cognition rates of dashboard understand the conditions which create a desired instrument panel.

The importance of the interaction capability of a robot increases as the application of a robot is extended to a human's daily life. In this paper, a portable mediate interface Handybot is developed with various interaction channels to be used with an intelligent home service robot. The Handybot has a task-oriented channel of an icon language as well as a verbal interface. It also has an emotional interaction channel that recognizes a user's emotional state from facial expression and speech, transmits that state to the robot, and expresses the robot's emotional state to the user. It is expected that the Handybot will reduce spatial problems that may exist in human-robot interactions, propose a new interaction method, and help creating rich and continuous interactions between human users and robots.

Recently, construction of soil-reinforced segmental retaining walls which used geosynthetics are being increased day by day due to its construction efficiency, economic efficiency, and its aesthetic view. The conventional reinforced earth retaining wall has the connector system to fix the reinforcement and block However, this system may cause the crack of block and the rupture of reinforcement due to the stress concentration near the face of reinforced earth retaining wall In this study, the new connector system, which is able to allow the settlement of reinforcement, was applied to analyze the effect of connector system of reinforced earth retaining wall The connection strength tests and centrifugal tests for both the conventional reinforced earth retaining wall and the settlement reinforced earth retaining wall were performed to compare the results

본 논문에서는 옴니버스 형태의 동영상을 각 프로그램 별로 자동 분할하는 방법에 대해 제안하고자 한다. 국내 TV 프로그램의 경우 대부분의 개그 프로그램에서는 코너 별로 상단 또는 하단의 일정 위치에 코너명을 캡션으로 삽입하여 옴니버스 형태의 영상을 서비스한다. 이러한 코너명을 태깅아이콘으로 하여 지속되는 구간을 검출하여 시작시점과 종료시점을 검출함으로써 동영상을 의미적으로 분할 할 수 있다. 하지만 태깅아이콘의 경우 매우 높은 투명도를 갖는 경우가 많으므로 본 연구에서는 에지와 시간적인 지속성을 이용하여 에피소드를 분할하는 방법을 제안하고, 옴니버스 형태의 다양한 개그 프로그램에 대해 실험하여 제안한 방법의 우수성을 보인다.

선교에는 항해사에게 정보를 전달하기 위하여 다양한 신호가 존재한다. 항해 및 통신 장비로부터 나오는 음향 신호 등 다양한 청각 신호들이 존재하지만 이러한 청각 신호, 청각 경고음에 대한 인간의 인지능력에 관한 연구는 미흡한 실정이다. 청각 경고음은 크게 음성(speech), 함축적 소리(abstract sound), 청각 아이콘(auditory icon)으로 구분 할 수 있다. 본 연구에서는 청각 경고음 중 청각아이콘을 활용하여 5가지의 경보상황(엔진, 화재, 조타, 전기, 충돌)에서 청각아이콘에 대한 감성평가를 통해 각 상황에 적합한 청각아이콘을 선별하였다. 본 연구 결과는 선교 내 청각표시장치와 통합선교알람관리시스템을 위한 기초자료로 활용될 수 있을 것으로 기대된다.
