The father was found to stay together with the child 0.5%-25% of the time when both father and chitd stayed at home. The use of the living room as the place in which the child stays with the father and tatks was found to be highest （five out of seven families）, fotlowed by the dining room and the child＇s room. In over half of the cases when the child stays with,the father in the living room or dining room and either of them tatk, the chitd spoke over 1.6 times more than the father. However, in the child＇s room, the child always spoke tess than the father, and the duration of the child＇s speech was less than 70% of that of the father. Findings showed that the instances in which child and father stay in different rooms fell into two groups. First, five of the seven subject fathers tended to stay in the living room, whereas the children stayed either in their room or in their parents＇ room to use the PC. Second, two fathers stayed in the studio or dining room to work, while their chitdren stayed in the living room or their own rooms. For both groups, the duration展开更多

The systems commonly used for this purpose do not include individual monitoring or are too expensive and intrusive to be deployed in common situations. In this project, a mobile system based on energy-efficient wireless sensor networks (WSNs) and active radio frequency identification (RFID) has been developed to achieve ubiquitous positioning and monitoring of people in hazardous situations. The system designed can identify each individual, locate him/her, send data regarding their physical situation, and ascertain whether they are located in a confined space. A new algorithm called time division double beacon scheduling (TDDBS) has been implemented to increase operation time and data transmission rate of the nodes in the system. The results show that the use of this system allows us to find the location and state of a person, as well as to provide an analysis of the potential risks at each moment, in real time and in an energy-efficient way. In an emergency, the system also allows for quicker intervention, as it not only provides the location and causes of the event, but also informs about the physical condition of the individual at that moment.展开更多
