일인가구의 증가 및 소비행태의 변화, 그리고 마트는 대형화 되고 있는데 반하여 포장 형태는 소포장 용기로 바뀌고 있으며, 수출되는 농산물 특히 과일 및 관련 작물의 수출시 소규모 패키지화되고 있고, 수출시점에 CO₂등의 선도처리를 하고는 있으나 운송 기간내 패키지내부 작물의 선도를 보장하기 어려웠다. 따라서 농산물 유통시 운송과정이나 진열시에 품온이 바뀌어 미생물에 의하여 작물이 변질되는 것을 방지하기 위한 신선도유지제로 소포장 용기로 유통하는 농산물에 적용하기 위한 새로운 신선도 유지 방법의 제공이 필요한 상황으로 윤통과정의 혁신을 가져올 수 있는 방안에 대하여 연구하게 되었다.

BRIS has been established by the Ministry of Agriculture, Food and Rural Affairs since 2011 under Article 21 of the Act on the Preservation, Management and Utilization of Agricultural Life Resources. It is an information service that provides information related to agricultural life resources in connection with the Rural Development Administration, the Forest Service, and Korea Seed & Variety Service, Agricultural Resources and Agricultural and Livestock Quarantine Headquarters. The purpose of this study is to evaluate how the users assess the information system quality (information quality, system quality) for the current Bio Resource Information Service (BRIS). Ultimately, the structural equation modeling analyzes the causal relationship between each variable and how it responds to the user's continuous use intention. As a result, information quality among information system quality and information quality among system quality used as the main variables for the evaluation of BRIS were statistically positively influenced by users' perceived usefulness, while system quality It has been analyzed to have a positive effect on the sustained use intention. The user's continuous use intention is positively influenced by the information system quality and perceived usefulness at a statistically significant level. Especially, the perceived usefulness plays a role in mediating the user's continuous use intention.

Rural information sector is a strategic planning of agriculture in 21st century for the advancement of agricultural competive power and quality of life to farmers. In order to advance the agricultural competency and quality of life, firstly, it is necessary that rural information sector should focus on the foundation of agriculture and rural information. Secondly, it should construct an area of function and item in application systems. Thirdly, it must Improve to culture of agriculture and rural information. It should be able offer a variety of educational information to help build a recognition and accommodation of value of agricultural information. The agriculture and rural information sector is so desirable that an organization should take exclusive responsibility to maintain the public property of it and to guard it from variable pressure groups. Therefore, to the uninformed mind, it is desirable to build and nurture KICAFF(Korea Information Center for Agriculture, Forestry & Fisheries) which is empowered in the information business- instead of the government. This is necessary for agricultural information system preservation because law and institution corresponds with role and function of the information/education system.

The wild silkmoth Antheraea yamamai Guérin-Méneville, 1861 (Lepidoptera: Saturniidae) is an important producer of silk that is superior to the silk produced by traditional domesticated silkworm. In this study, we sequenced the complete mitochondrial genome (mitogenome) of An. yamamai collected from Jeju Island, which is the southernmost island approximately 100 km offshore southward from the Korean Peninsula. Determining this sequence will be necessary for tracing the biogeographic history of the species and developing molecular markers for identifying the origin of commercial products. Comparison of the sequence divergence among two available and the current mitogenomes revealed a low but substantial number of substitutions, totaling 23 nucleotides in the whole genome. CytB and ND5 showed the highest variability with five and four variations, respectively, suggesting that these regions will be prior regions to target for subsequent biogeographic and diagnosis study. Phylogenetic reconstruction based on all available sequences of Saturniidae showed that An. yamamai is a sister to the congeneric species An. pernyi, corroborating that Antheraea is a highly supported monophyletic group. The tribe Saturniini was clearly non-monophyletic and interrupted by Attacini and Bunaeini.

Along with global warming, ever intensifying weather events have increased damages to agricultural farms and facilities. The objective of this study was to investigate the spatial distribution and regional characteristics of agricultural damages by extreme weather events. Agricultural disaster statistics provided by the National Emergency Management Agency were summed over for a 13-year period from 1998 to 2010 and used for the spatial analysis. Two indices of damage area ration and property damage per unit area were introduced to quantify regional agricultural damages. As the results, farm inundation accounted for the largest area primarily damaged by typhoons with heavy rainfalls. Most property damages to farm lands originated from farm erosion in the alpine regions by localized guerrilla rains. The two major causes of damages to greenhouse and livestock facilities were typhoon with strong wind and winter blizzards. Gangwon was the province of the largest property loss mostly from farm land erosion losses, followed by Gyeongnam, Jeonnam, and Chungnam where losses to greenhouse and livestock facilities were relatively greater. Property loss per unit area was also the greatest for the Gangwon province (4.91 M\/ha), followed by Gyongnam and Chungnam of 2.20 and 1.50 M\/ha, respectively. Unit loss for greenhouse and livestock facilities was 13.3 M\/ha, approximately 13 times greater than that for farm land (1.06 M\/ha). The study findings indicated the importance of reducing highland farm erosion and reinforcing farming facilities structures for agricultural disaster management.
