        This paper provides data for product development and improvement of grape varieties by analyzing the satisfactionimportance of the grape selection attributes from a consumer's perspective. A survey was conducted on consumers aged 19- 59 living in Seoul, Gyeonggi and Incheon on their fruit consumption level, preferences according to the grape quality characteristics, importance, and satisfaction with the grape selection attributes. Three hundred and eighty two valid samples were collected and analyzed statistically using SPSS 23. In the preference according to the grape quality characteristics, consumers tended to prefer a sweet taste, black color, and seedless grapes. Regarding the importance of the grape selection attributes according to the level of grape consumption, the high consumption group considers texture, size, shape, color, ease of removing seeds, country of origin, area of production, certification, and brand to be more important. In satisfaction, the high consumption group rated satisfaction highly in texture, odor, size, shape, color, ease of removing peelings, ease of removing seeds, price, country of origin, area of production, certification, and brand. An analysis of the IPA of the grape selection attributes showed that improvement of price and shape attributes will be prioritized, and the development and management of properties, such as seeds, peelings, certification, and brand will be required. These results can be used to help improve the grape varieties and develop products that meet the consumer needs, secure the competitiveness of grape farmers, and revitalize the local economy.

        The purpose of this study is to analyze the distribution characteristics of mist spray particle size by devising a rotary mist spraying device to develop the evaporative salt water desalination system. The rotary mist spraying device was consisted of a BLDC sirocco fan, a spinning fan, a fan fixed shaft and a salt water supply device etc. In this study we analyzed the characteristics of spray particle size and distribution according to the variation of sirocco fan surface roughness(Ra, μm), revolutions(rpm) and salt water flow rate(mL/min). When sirocco fan surface roughness( Ra) was in the range of 0.27~7.65 μm, the spray particle size was 0.117~1.360 μm. And then more than 90% of spray particles were found to be less than 0.50 μm. When sirocco fan surface roughness(Ra) was in the range of 12.70~22.84 μm, the spray particle size was 2.51~184.79 μm and more than 98% of spray particles were found to be less than 13.59 μm. To analyze the effect of fan rotation speed on the size and distribution of spray particles, when surface roughness Ra was fixed 0.27 μm and fan rotation speed and salt water flow rate was respectively changed at 3,800~5,600 rpm and 2.77~8.28 mL/min, spray particle size was 0.341~0.541 μm. And when salt water flow rate was 9.74 mL/min and fan rotation speed was 3,800~5,200 rpm, spray particle size was in the range of 29.29~341.46 μm and in case of 5,600 rpm more than 98.23% of spray particles were in the range of 2.51~13.59 μm.

        The purpose of this study is to suggest structural model and analyze design factors for the development of small greenhouse standardization model. The average dimensions of small greenhouse desired by urban farmers were 3.3m in width, 1.9m in eaves height, 2.7m in ridge height, 5.7m in length. The cladding materials for small greenhouse were preferred to glass, PC board and plastic film, framework to aluminum alloy and steel, and heating method in electrical energy. In addition, it was analyzed that small greenhouses need to develop structural model by dividing them into entry-level type and high-level type. The roof type that was used for entry-level type was arch shape, framework was steel pipe, cladding material was plastic film. On the other hand, high-level type was used in even span or dutch light type, framework with square hollow steel, cladding materials with glass or PC board. In consideration of these findings and practicality, this study developed four types of small greenhouses. The width, eaves height, ridges height, and length of the small greenhouses of even span type, which were covered with 5mm thick glass and 6mm thick PC board were 3m, 2.2m, 2.9m, and 6m, respectively. The small greenhouse of dutch light type covered with 5mm thick glass was designed with 3.8m in with, 2.2m in eaves height, 2.9m in ridges height, and 6m in length. The width, eaves height, ridges height, and length of the arch shape small greenhouse covered with a 0.15mm PO film were 3m, 1.5m, 2.8m, and 6m, respectively.
