Mobility Model has drawn more and more attentions since its critical role in Mobile Wireless Networks performance evaluation. This paper analyzes the mobility patterns in the catastrophe rescue scenario, and proposes the Random Waypoint with Base Point mobility model to model these characteristics. We mathematically analyze the speed and spatial stationary distributions of the nodes and derive explicit expressions for the one dimensional case. In order to keep the stationary distribution through the entire simulation procedure, we provide strategies to initialize the speed, location and destination of the nodes at the beginning of the simulation. The simulation results verify the derivations and the proposed methods in this paper. This work gives a deep understanding of the properties of the Random Waypoint with Base Point mobility model and such understanding is necessary to avoid misinterpretation of the simulation results. The conclusions are of practical value for performance analysis of mobile wireless networks, especially for the catastrophe rescue scenario.

Purpose: This study was conducted to determine effective chest compression methods that could be used when performing cardiopulmonary resuscitation in rocking boats. Methods: Tests were conducted for four minutes using manual and mechanical chest compressions on two mannequins, placed in boats, and moving at a speed of 35km/hours on calm sea surfaces with wave heights of 0.5m and wind speeds of 2-3m/s (testing for two minutes, followed by rest, then a second round of testing for two minutes). To compare the quality of the chest compressions, data were analyzed using mannequins (Resusci Anne Q-CPR, Laerdal, Norway) and then statistically processed. Results: When chest compressions were administered in the moving rescue boat, an accuracy analysis showed that the pressure speed of the hand and mechanical techniques were normal, h owever, the pressure depth accuracies were 49.04% for manual techniques and 0% for mechanical techniques. The relaxation accuracies during compressions were 2.07% for manual techniques and 95.4% for mechanical techniques. Conclusion: When administering chest compressions in rocking rescue boats, mechanical rather than manual techniques should be preferentially considered.

The objective of this study is to evaluate the relationship of hopelessness and suicidal lethality of suicide attempters. The subjects were 72 persons who attempted suicide and came to the emergency room of Chungbuk National University Hospital from April 1st, 1995 to March 31st, 1996. The hopelessness of suicide attempter was assessed by Beck Hopelessness Scale(BHS), and the suicidal lethality was assessed by Risk-Rescue score. The Risk-Rescue Scores exhibited no significant differences in demographic characteristics (sex, age, education, religion, marital status, socioeconomic class, occupation) and psychiatric diagnoses. But the Risk-Rescue scores were significantly higher in high BHS group(BHS score ${\geq}$ 9) than in low BHS group(BHS score <9) and positive correlation was observed between the BHS and the Risk-Rescue score(Rs=0.77 : p<0.05). These results suggest that level of hopelessness be a major risk factor for suicidal lethality.

Under the situation of a fire, it is difficult for a rescue robot to use sensors such as vision sensor, ultrasonic sensor or laser distance sensor because of diffusion, refraction or block of light and sound by dense smoke. But, braille blocks that are installed for the visaully impaired at public places such as subway stations can be used as a map for autonomous mobile robot's localization and navigation. In this paper, we developed a laser sensor stan device which can detect braille blcoks in spite of dense smoke and integrated the device to the robot developed to carry out rescue mission in various hazardous disaster areas at KIST. We implemented MCL algorithm for robot's attitude estimation according to the scanned data and transformed a braille block map to a topological map and designed a nonlinear path tracking controller for autonomous navigation. From various simulations and experiments, we could verify that the developed laser sensor device and the proposed localization method are effective to autonomous tracking of braille blocks and the autonomous navigation robot system can be used for rescue under fire.

The purposes of this study were to investigate the current performance of 119 rescue uniforms and to improve them in terms of fitness, mobility, functionality, and convenience. This study was conducted a questionnaire survey on rescuers in 22 rescue squads in Seoul through direct. observations and face-to-face interviews to investigate the dissatisfaction of their uniforms. According to the results of this survey, respondents were highly dissatisfied with the fitness of uniforms, design, and functionality. liking into consideration of the problems found through this survey, an experimental uniform was developed as follows. The girth and width of the experimental uniform were designed to be more ample than the current uniforms and the jacket could be worn over pants. And the size and the number of pockets were increased in both the Jacket and trousers. In addition, the hems of the sleeves and trousers as well as the fly front of the jacket were improved. Furthermore, darts were added to the front and back of the knees to improve knee movement. Then an experimental uniform was evaluated through three sequences of wearing tests to compare it with the current uniforms: the evaluation of the appearance, mobility. and performance at field activity. According to these tests, the experimental uniform was found to be more satisfactory than former one.

In this study, the 1/35 reduced-scale model experiment were conducted to investigate designed ventilation effect on the smoke movement at rescue station fire in railway tunnel. A model tunnel with 2 mm thick, 10 m long, 0.19 m high and 0.26 m was made by using Froude number scaling law. The cross-passages installing escape door at the center were connected between incident tunnel and rescue tunnel. The n-heptane pool fires with heat release rate 698.97W were used as fire source. The fire source was located at the center and portal of incident tunnel as worst case. A operating ventilation system extracted smoke amount of 0.015 cms(cubic meters per second). The smoke temperature and CO gas concentration in cross-passage were measured to verify designed ventilation system. The result showed that, at center fire case without ventilation, smoke did not propagate to rescues station. In portal fire case, smoke spreaded to rescues station without ventilation. But smoke did not propagated to rescues station with designed ventilation.
