In this study, distributed the ship's Centralized Air Conditioning System the way an individual to replace the air conditioning system by using Air-cooled air conditioner. Research results, Individually separated air conditioning system complement the heat source control and thermal efficiency problems and improves the efficiency of the device was confirmed. In addition, under the same conditions refrigeration capacity and coefficient of performance of the device, an average of about 3 %, 23 ~ 26 %, higher, Chilled Water Plants Compressor power consumption is about 12 % lower. Also while heating under the same conditions, power consumption is about 33.5 % lower. Therefore Individually Separated Air Conditioning System greatly contributed to the improved performance of the device and living spaces for comfortable temperature and humidity control as well as heating source could be obtained.

In this study, Mokpo national maritime university Training ship Centralizes Air Conditioning System was upgraded by installing onboard an Air-cooled Air conditioner. This resulted in the improvement of the performance and operation. This study compared refrigeration performance to former equipment and improving one. And through the actual measurement study about the cabin thermal environment, it will be used as basic data for marine air conditioning design and plan in the future. At same climate condition, when the Centralized Air Conditioning System and an improved air conditioning system operated, cabin temperature was at $24{\sim}28^{\circ}C$, humidity was 55~75 % as comfortable condition, Generator load measurement showed a saving of 48KW in the average load and 8 % in the full load factor. This also resulted in a saving of daily fuel oil consumption(FOC) at around 222 [${\ell}/day$] average. On the other hand, one cadet cabin(Cadet No.21) indicated a higher temperature due to heat transmission of engine room. It found us not to consider installing additional diffuser to reduce the heat transmission.

인류가 살아온 역사는 재난을 극복하기 위한 과정의 연속이였다. 효율적인 재난 대응을 하기 위해서는 중앙정부 뿐만 아니라 지방자치단체도 통합관리체제로 재편되어야 할 것이다. 기초자치단체의 재난관리체계가 상당히 미흡한 상태이기에 광역지방자치단체와 긴밀한 상호공조체제 유지로 역할 분담을 명확히 하여 신속하고 체계적인 대응체계를 구축하고, 재난관리 전문인력을 집중 육성 및 구난장비의 확충과 더불어, 국민들의 안전의식 수준을 향상시키고 위기 상황발생시 극복할 수 있는 가상체험 훈련 등을 통하여 유사시에 대비할 수 있도록 한다. 또한 재난관리 정보시스템을 설계하고, 재난관리 대응매뉴얼을 활용하여 재난시 국민들이 슬기롭게 대처하여 재난피해를 최소화 하는 방안을 강구하여야 한다.
