Korean traditional alcohol's growth gets declined after Makgeolli's boom and it's time to enter the takeoff stage using cup based on the characteristics of each alcohols in order to their globalization and quality improvement. For now, there are 3 features of Korean traditional alcohol's cup design development; subdivision, quality improvement, systematization. However, there's no product design case that reflect the characteristics of the alcohol from the planning phase. Therefore, it needs to establish process technology for storytelling and emotion based cup design. This research aims to extract the specification for cup design and to find out the visualization element of cup's shape and material by studying 5 senses and traditional alcohol's objective informations. Through the study, the elements that can maximize the specific traditional alcohol's marketability: cup's label, pattern, decorative element based on the storytelling like history and tale were found. As a result, those result can give a new export strategy by developing competitive design that has emotional element and storytelling from the traditional alcohol's characteristics in a situation of stagnant export of the small sized home-brewed liquor business.

Seasonal occurrence of thrips and its damage on fruits were studied at in open field red pepper in Jeonbuk Province. The kind of thrips were Franklinella occidentalis and F. intonsa. The ratio of F. occidentalis was about 30% in periods of survey. Density of thrips increased in late May and showed peak occurrence in early to middle July. The peak occurrence of thrips was appeared at 4 pentad June, 2 pentad July, 3 pentad August, and 4 pentad September. The part of fruit damaged by thrips became discolored and roughed. When turned red, the colors of damaged parts changed from dark brown to yellowish brown. As a result, damage fruits by thrips decreased marketability. The percent of damaged fruits was highest in Imsil at 20.8% in early August. Density of thrips on flowers was highest in middle July.

1. The purpose of this study was to recommend ways of more efficient pheasant farm business management and promoting the demand of pheasant foods by reviewing the current pheasant farm business management and the general pattern of consumption of pheasant foods. The study was conducted on the basis of the field survey covering 83 pheasant feeders and 283 consumers. 2. Majority of pheasant feeders, 86.8%(n=72), utilized broiler feed for pheasant rearing because of high price of exclusive pheasant feed. 3. In case of producing 1,000 heads of 5 month-old pheasant, the primary production cost per head was roughly calculated at about 5,530 Won. And 40.3% of primary production cost was consisted of feed cost and 12.9% was depreciation cost for facillities including artificial incubator equipments. 4. 81.1%(n=51) of whole surveyed feeders disposed of 1-4 week-old birds directly to the new feeders and 6%(n=6) sold them to the middlemen who were almost pioneering pheasant feeders. 5. 48.9%(n=138) of the surveyed consumer respondents have taken the pheasant foods once and several times, and the others never once. And 50.6%(n=69) of the respondents who had taken the pheasant foods were satisfied with the tastes. 6. The surveyed consumers were asked whether they knew the nutritional value of pheasant foods and 47.3(n=136) recognized it positively and 37.5%(n=106) negatively. 7. To increase the pheasant farm income and promote the demand of pheasant foods. followings are recommended. - Production cost should be reduced by cooperative utilization of facilities and equipments at farm level, and exclusive pheasant feed of good quility should be developed and supplied to the feeders at a low price. - Pheasant marketing and pricing system should be improved to prevent consumers from price disorder of retail shop including pheasant food reataurants and to popularize the pheasant foods. - Various type of menu of pheasant foods should be developed not only to satisfy consumers in tastes but also to solve the seasonality of pheasant supply. But it is preferable that this action is led by pheasant feeders and their cooperative organization, espectially through vertical intergration system owned by pheasant feeders. - Generic, pioneering advertisement and promotion should be carried out to promote primary demend of pheasant foods. It would be preferable that these primary demend advertising and promoting activities shuld be sponsored by pheasant feeders and government together. And their activities should be supported by institutional regulation.

It is necessary to effective temperature and humidity management for normal growth of crops in protected cultivation during the summer season. Because the highest temperature of vinyl house inhibit normal growth of crop and decrease of crop production or marketability in summer season. Finally, the vinyl house was impossible some crop cultivation in summer season. This study was conducted to investigate effective and economic method for temperature drop in protected cultivation during the summer season. 1. In medium size vinyl house(5$\times$13$\times$3m), the effect of temperature drop appeared the highest in treatment of shading with aluminium thermal curtain＋fog system＋ventilation with fan. The effect of temperature drop was about 1$0^{\circ}C$ lower than outer air temperature and about 4$^{\circ}C$ lower than outer soil temperature. 2. The effect of temperature drop according to shading with aluminium thermal curtain＋fog system＋ventilation with fan during the highest temperature of summer season Jul., 20 to Aug., 21 was appeared about 8$^{\circ}C$ lower than outdoor above ground(1.2m) and about 7$^{\circ}C$ lower than outdoor surface ground. 3. The changes of solar radiation during a day according to shading with aluminium thermal curtain＋ventilation with fan and shading with black curtain＋ventilation with fan treatments was appeared respectively about 29.3%, 32.5% of outdoor solar radiation a fine day and respectively about 27.4%, 31.8% of outdoor solar radiation a cloudy day.

A study was conducted to examine the effect of precooling (2, 4, or $8^{\circ}C$) and storage (4, 8, or $10^{\circ}C$) temperatures on the storage life of 'Maehyang' and 'Soogyeong' strawberries for export. Fruits at a 70% ripe stage were harvested from a commercial greenhouse in Jinju on March 16, 2010. Fruits were precooled by a forced draft cooling for 3 hours, transported for about 30 minutes to a lab., and then stored. For precooling, small precoolers set in the farm were used. During storage, fruits were examined for their changes in weight, hardness, color (hunter value), soluble solid content, incidence of gray mold (Botrytis cinerea), and marketability at a two days interval from March 16 to March 30. In both cultivars, hardness, sugar content, and hunter value were higher in 'Soogyeong' than 'Maehyang'. The greatest hardness and soluble solid content were obtained after storage at $4^{\circ}C$ in both cultivars. As the ripening stage progressed, hardness and soluble solid content decreased. Also, fresh weight decreased during storage at all temperatures. Gray mold was the greatest at $10^{\circ}C$ storage temperature. The results indicate that effectiveness for keeping the freshness was best achieved by precooling at $2^{\circ}C$ and storage at $4^{\circ}C$ in both cultivars.

Bark is a general medium for potted Cymbidium in Korea, but it is difficult to shake off or eliminate the medium from the roots before exporting the potted plants. This working process can injure the roots and then deteriorate plant marketability. This study was carried out to select the optimum medium easier to eliminate from the roots instead of bark and the optimum amount of applied fertilizer to improve the plant growth. Cymbidium young plants 'Honey Hot' and 'Desert Look' were planted in pots with bark, cocochip, and peatmoss. The plants were treated with 2, 4, and 6 g of slow release fertilizer. The plant growth characteristics were investigated in the first and second years during production period of three years. The medium characteristics and mineral nutrient content of the leaves were also examined in the second year. In the first year, the plant growth of 'Desert Look' was improved in all peatmoss treatments more than bark. 'Honey Hot' showed the highest plant growth values in the bark treatment. In the second year, the plant growth of the two cultivars was improved in peatmoss. Cocochip treatments showed the lower plant growth values than bark and peatmoss in the first and second year. There was no significant difference among fertilizer amounts in all the media. The higher CEC values of peatmoss medium resulted to higher capacity to hold more nutrients than bark, and the nutrient retention of the peatmoss improved the plant growth. The higher K and Ca contents in the leaves would contribute to improve the plant growth. Consequently, it would be possible to use peatmoss instead of bark for Cymbidium young plants, but there must be always attention to appropriately water the medium and manage the moisture.

'Hanareum' pear is expected to produce the high quality small and medium-sized fruits without any major changes in the current cultivation techniques, inasmuch as its basic characteristics are already included in the range of small and medium-sized fruits. Thus, we tested the possibility of utilization of 'Hanareum' pear for producing small and medium-sized fruits, while establishing the limit of minimum fruit weight for the fruits in high quality. With the results of correlation analysis, it was possible to predict the fruit weight through the observation of soluble solid contents and flesh firmness, because both factors were closely correlated to fruit weight in all treatments. Moreover, these factors were confirmed to be useful indicators of forecasting consumer preference in the sensory evaluation. The fruit marketability was excellent under the conditions that were greater than $11.6^{\circ}Bx$ and less than 25.6 N for soluble solid contents and flesh firmness, respectively. When applying these standards of fruit quality to the results of regression analysis for fruit weight, non-treated fruits fulfilled both standards when the fruit weight was higher than 436 g, and the quality uniformity was also high on this state. Therefore, the production of high quality small and medium-sized fruits was determined to be under this condition. The weight limit for GA treated fruits was 620 g, and both fruit quality and uniformity were below the weight range of small and medium-sized fruits, with 300~500 g. Thus, GA treatment was suggested to be avoided, in order to produce the high quality small and medium-sized fruits.

This study was conducted to determine the influences of winter and summer pruning on the yield and fruit quality in southern highbush blueberry (Vaccinium corymbosum L. hybrid) cv. 'Misty'. The 5-year-old southern highbush blueberry 'Misty' were used. The pruning treatments were as follows: 1) control (no pruning), 2) winter pruning (30% removed), and 3) winter pruning + summer pruning (Aug. 5). Fruits harvested for six times over the harvest season and measured yields, unmarketable fruit (defected and immature fruit), changes of each fruit weight and analyzed fruit characteristics, such as total sugar, total anthocyanin contents and total phenolic contents. The differential pruning treatments were not significant for fruit yields of southern highbush 'Misty'. No pruning treatment showed regular yields after the 2nd harvest, but the other pruning treatments were appeared that fruit yields were more concentrated on the 2nd~4th harvest time. Total sugar and total phenolic contents were observed the highest at the 4th time among the harvest period. No pruning treatment showed the highest unmarketable fruit yield at 57%, however, that of winter pruning and winter + summer pruning treatment occurred at 26%, 31%, respectively.

Recent automobile manufacturing technology has improved not only the function and performance of cars, but also the audio systems in cars so as to increase their marketability. Automobile manufacturers always have the option of simply installing an expensive acoustic system to help customers enjoy a high-level sound quality car audio system. However, this also tends to increase the MSRP (Manufacturer's Suggested Retail Price) of the car. Therefore, it is desirable, where possible, to enhance the sound quality of plainer, less expensive audio devices to help customers feel as if they have a high-quality and expensive audio device in their car. In order to make this happen, the manufacturer must develop an optimal interior environment and audio system at a relatively lower cost. To this end, features of the car audio system can be enhanced by analyzing audio frequency response and using performance metrics to figure out the characteristics of the human auditory system. This study analyzed the sound field of Korean Recreation Vehicles (RVs) using the Internet of Things (IoT) sensor for the measurement of car audio system. As a result, high energy of sensitive bandwidth, one of the human auditory characteristics often makes annoying sound. This study also found that increasing the frequency response flatness is required by taking human auditory field into account when designing the car audio system for the future.
