Many countries have introduced new imported food safety measures, following the accident at Fukushima Daiichi Nuclear Power Station. This study was conducted to evaluate the measures contents and effects on food trades values. Eight percent of members were notified the introduced measures to the World Trade Organization. The measures' contents were banning imports, enhancing inspection and adding certification requirement. The covered regions were some prefectures, entire Japan or all affected countries. European Union introduced a measure that subjecting foods originating from 12 prefectures to import at designated ports with required certification. The measures were amended 8 times until March 2014 to apply listed foods from 15 prefectures. The trade value of fishery products and miscellaneous foods were affected. Australia introduced a measure that required additional inspection of dairy, fishery and plants products from 13 prefectures with subsequent amendments. The trade value had no effect in tested foods. Chinese Taipei introduced a temporary import ban for all foods from 6 prefectures. Trade values for fruits were affected. The United States issued an import alert for detention without examination for listed prefectures and goods without introducing new measures. Although no specific products were affected, trade values for all foods were affected.

The strategy of maintenance was improved from the Break-down maintenance strategy, which is only for broken-down equipment, to the Preventive maintenance strategy. The Proactive maintenance strategy involves doing maintenance when data and sensors indicate it is needed, rather than after the equipment has broken down. The ROK Navy may want to adopt the Reliability centered maintenance strategy, which combines the Preventive and Proactive maintenance strategies. By this study, I suggested the applicability of the Proactive maintenance and its future with the vibration data analysis of the ***class **ship. Then, the remaining useful life of the ship was calculated with empirical equations for concatenate curve fitting. In the future, more reliable proactive maintenance will be possible using the improved automatic vibration data recording system.
