The cruiser trip which can have various experiences in a short time is growing as the best tourism package because there is less leisure time in contrast of the increased income in 21C. in other words, as the demand of the tourist goes up, the number of ships built newly is increasing. The order of the ship keeping first and second rank in Korea has arranged a long-term strategy in order to get into the global market with the cruiser with the high value added. They also set the objective related to the cruiser design and skillful construction work. We need to observe the change and trend of the cruiser with a care at this time when the cruiser industry is launched out. In this study, the cruiser industry is divided by four periods: the spring time, the depressed time, the developing time and the peak time, on the basis of the trend of the development and the change of space structure. In addition, it was analyzed in this study that there were the various trends such as the ratio, the structure and the type of the space as well as the interior plan in the passenger's residential place The aim of this study is to present the fundamental material about the interior plan to prepare for building the domestic cruisers in a foreseeable future.

In case of a fire in road or railway tunnel it is always necessary to keep the escape condition as good as possible. Most of the victims of major fires in tunnels are because they couldn't leave the tunnel in time and were trapped by smoke, or rescue teams couldn't reach the place of the accident due to low visibility and high temperature. In spring 2003 a comprehensive field experiment was undertaken in a large scaled tunnel in Youngin City to test the effectiveness of a new water spray curtain system, designed to the air qualify inside of a tunnel in case of fire during passenger's escape to safe routes, In order to control the smoke propagation, fixed water sprayed nozzles were used to make water curtain system, which can be installed or hanging water piping line below ceiling. The experiment was accompanied by an extensive measurement campaign in order to measure temperature dropping effect and flow conditions as well as CO concentration for various water sprayed curtains produced by sprinkler heads or water spray nozzle. Eventually comparison analysis were undertaken to investigate the performance of water curtains under fixed water pressure. Therefore most effective water curtain system was presented on the basis of water droplet size in long tunnel.
