Abstract: PURPOSE: An emergency rescue system and a method for detecting position are provided to transmit an emergency rescue signal to a terminal in remote site within constant distance from the terminal using a zigbee module even in case a rescue request person does not possess the terminal. CONSTITUTION: A zigbee module generates a rescue request signal. A terminal receives the rescue request signal and sends to a central control chamber using conventional communications network. The central control chamber receives the rescue request signal and detects a broad area location using the location of the terminal and dispatches a rescue team. The rescue team moves to the broad area location and detects the location of the zigbee module by directly receiving the rescue request signal generated from the zigbee module.
Abstract translation: 目的：提供一种紧急救援系统和一种检测位置的方法，即使在救援人员不拥有终端的情况下，也可以使用Zigbee模块将紧急救援信号发送到距离终端不变的远程站点的终端。 构成：ZigBee模块产生救援请求信号。 终端接收救援请求信号，并使用常规通信网络发送到中央控制室。 中央控制室接收救援请求信号，并使用终端的位置检测广域位置，并派遣救援队。 救援队移动到广域位置，通过直接接收由ZigBee模块生成的救援请求信号来检测Zigbee模块的位置。

Abstract: PURPOSE: A system and a method for preventing the occurrence of a missing child are provided to continuously check a distance between a location transmitter and a location receiver, thereby preventing a situation of a ward to be a missing child in advance. CONSTITUTION: A location transmitter(10) periodically sends a location signal. A location receiver(20) receives the location signal and determines spaced distance with the location transmitter. If the spaced distance escapes the preset range, the location receiver generates an alarm signal. The location transmitter and the location receiver directly exchanges signals wirelessly in a close distance. The location transmitter is mounted to a mobile phone of a guardian.

Abstract: A VOD(Video On Demand) service providing method and a recording medium for recording a program thereof are provided to manage a bandwidth of a content server efficiently in consideration of the number of terminals which request or receive a VOD service. A VOD service providing method comprises the following steps of: providing VOD streaming data responding to a VOD service request from one or more terminals(100)(S540,S550); computing an optimum transmission mode by using preset correlation; and converting a current transmission mode into the optimum transmission mode if the current transmission mode between a content server(130) and the terminal is different from the optimum transmission mode(S520). The correlation uses one or more terminals connected to the content server, a bandwidth assigned to the content server, and a payment policy.
