This study is a survey on the general perceptions of the residents and visitors regarding the Nature Restoration Period in Chilsun Valley in Jirisan National park, and it was designed to establish systematic park management plan for the Special Protected Areas in Korean National Parks. This survey was conducted on the residents of five towns including Chuseong-ri, Gwangjum-dong, Uijung-ri, Uitan-ri and Uipyeong-ri, as well as visitors to Chilsun Valley by using convenience sampling. The result showed that those individuals or groups who responded to the survey were all positive about preservatory effect of Nature Restoration Period in the valley; however they also showed major perceptional differences as to the ways in which the nature restoration period managed. They also disagreed among themselves on the assessment of the extent of damage that could be generated due to the restoration, the appropriateness of the Nature Restoration Period as a management policy and maintenance of the policy in the future. The appropriateness as a policy and the extent of damage due to the Nature Restoration Period particularly showed some serious perceptional differences among five resident groups based on the location of their towns. To minimize current conflict and achieve the goal of Nature Restoration Period, the park management authorities need to communicate more actively with the stakeholders of the local community and NGOs, and secure their support and cooperation by accommodating their ideas and opinions to build a strategic partnership.

Activity of the noncontacted low temperature atmospheric pressure surface discharged plasma (LASDP) converts stable gas to ionized gas known as discharge or plasma. This ionized gas exhibits the antimicrobial activity. We examined the effects of 3 different storage treatments for 80 days on 'Setoka' : ambient storage (AS), low-tempperature storage (LTS), and low-temperature atmospheric pressure plasma+low-tempperature storage (PLTS). Total soluble solids showed no the significant differences between the 3 treatments. Acidity gradually decreased, and was 0.5% under AS after 30 days of storage. Fruit firmness increased by a few percent until 40 days of storage. Weight loss in AS was higher than for other treatments. After 80 days of storage, the decay ratio was significantly low in PLTS treatment: (AS, 50.5%; LTS, 5.6%; PLTS, 1.9%). In AS treatment, 73% of the rotten fruits were infected particularly with green and blue mold; however, only 1% of the rotten fruits were infected in case of PLTS treatment. In conclusion, LASDP treatment can prevent postharvest decay caused by fungi and is an efficacious alternative extending the shelf-life of citrus fruits.

Such fruits as nut persimmons, mandarin oranges and apples stored in the far-infrared radiated chamber at 5$^{\circ}C$ under 90% of relative humidity had been maintained in the fresh state for longer times than the control stored only in the cold chamber. Fruits stored in the far-infrared radiated chamber showed lower values in weight loss rate, microbial colony count and decay ratio and higher ascorbic acid content than the control stored only in the told room through the storage period. We confirmed that fruits stored in the far-infrared radiated chamber under low temperature and high humidity showed least changes in quality properties through the storage period and the far-infrared radiated facilities could be a good storage system.
