As a college dormitory has the features of high dwelling density and a floating population that becomes crowded during particular times, when a disaster such as a fire occurs, it has the risk of causing much loss of life. In this study, the fire simulation program Fire Dynamics Simulator (FDS), is used to predict the risk when a fire occurs, to analyze the problem, and to suggest an improvement plan for a new cadet dormitory at an university in Korea. The research results are as follows. When a fire occurred in the ironing room inside the cadet dormitory, a smoke detector operated after 65 seconds. Thirteen seconds later, a sprinkler started to operate. The temperature and carbon monoxide density reached the limit value at 241 and 248 seconds, respectively. Because the limit visibility value was reached within 66 seconds after the occurrence of a fire, it is predicted that preparation must be finished and evacuation should begin within 1 minute after the fire occurs, in order to have no casualties. Synthesizing this dormitory fire risk prediction result, the visibility value is considered to be the most dangerous factor for personal safety. Because of this, installing a smoke extraction system is suggested to secure visibility. After the installation of a smoke extraction system, the problem of smoke diffusion in the corridors improved.

In this study, the corelation among the knowledge of and attitude to health care and the actual health protective practices of seafarers was surveyed and analyzed in order to provide the management method for improving seafarers' health care. The subjects of this study were 516 seafarers who took refresh training courses in Korea Institute of Maritime and Fisheries Technology. The questionnaire was constructed under the Guidelines for National Health of the Ministry of Health and Welfare and modified for studying seafarers' health state. The collected data were analyzed by SPSS package. The results were as follows: 1) The older, married, religion believer, higher ranker, the man who have longer career have the higher degree of knowledge, attitude, and practice-degree(p<0.05). 2) The degree of knowledge, attitude, and practice are $4.24{\pm}0.35$, $3.45{\pm}0.41$, and $3.39{\pm}0.22$ in mean by 5-score scale, respectably. 3) The corelation among the degree of knowledge, attitude, and practice was significant(r=0.33~0.63, p<0.05).
