  • Reward-based crowdfunding is a funding platform that allows funds to be raised to early operators who have lack of funds, and is seen as an outstanding infrastructure that is going to lead the fourth industrial revolution in that it is a field of realization of new technologies and creative ideas by start-ups. Reward-based crowdfunding has grown in line with the trend of the fourth industrial revolution, and funding success cases are taking place in various industries that culture/art to technology/IT, including as a new means of knowledge management in a rapidly changing industrial environment. The study focused on the fact that consumer's donation purposes may also vary depending on the category of projects classified as reward-based crowdfunding. Because consumer payment decisions and motivation of consumer purchasing behavior are classified according to the purpose of purchase, the previous papers that the goal gradient effect that the main motivation of consumer donation for reward-based crowdfunding introduced vary depending on project category of utilitarian and hedonic. In this study, consumer's daily donation data is collected by Indiegogo which is a leading reward-based crowdfunding company using web-crawling and the model was defined as propensity score matching (PSM) and random effect model. The results showed that the goal gradient effect occurred in utilitarian project category, but no goal gradient effect for the hedonic project category. Furthermore, this paper developed the study of motivation of consumer donation and contributes theoretical foundation by the results consumer donation may vary depending on the project category; also, this paper has implications for an effective marketing strategy depending on the project category leaves real meaning to the projector.

  • Volatile compounds, isolated from Chopi (Zanthoxylum piperitum A.P. DC.) using steam distillation, were analyzed by gas chromatography/mass spectrometry-olfactometry (GC-MS-O). Forty-six volatile compounds, consisting of 12 hydrocarbons, 8 aldehydes, 5 esters, 12 alcohols, 4 ketones, 4 oxides and 1 acid, were tentatively identified from the essential oil of Chopi. Unidentified compounds constituted 7.2% of the total peak area. Limonene was the most abundant compound, followed by geranyl acetate, citronellal, cryptone and ${\beta}$-myrcene. In addition, aroma-active compounds, in particular citronellal and limonene, which are related to the citrus and Chopi flavors of Chopi essential oil, were detected. The aroma of Chopi essential oil had a score of 4.8 on the preference test (neither like nor dislike) and a score of 5.97 on the intensity test (slightly strong) using the 9-point hedonic scale.

  • To evaluate the methanol extract from Pinus strobus leave as a possible ingredient of health food, the sensory analysis and an animal experiment were designed using cookie, candy or chewing gum containing the methanol extract. Cookie, candy and chewing gum which contained 0.4%, 0.25% and 0.3% of the methanol extract, respectively, were prepared by Haitai Confectionary CO.. Sensory analysis of the products was evaluated by hedonic scale. Our results indicated that the addition of the methanol extract to the products provides better sensory perception in hedonic score and higher preference number than control, especially in candy and cookie. In the animal experiment, the chickens fed diet containing 10% of the cookie powder for 2 weeks exhibited a reduction of the serum cholesterol level by 18%, compared with the chickens fed basal diet. This result suggested that the methanol extract from P. strobus leave contained a potential ingredient to reduce the concentration of serum cholesterol. Therefore, extract from Pinus strobus leaves can be used as an ingredient of health food.

  • This study was carried out to investigate correlation with food preference of subjects in three constitution groups on the view point of constitutional medicine. The constitutions of 124 college students(male 80, female 44) was classified by QSCC II method. Food preference of the subjects was surveyed in accordance with suggested foods for each constitution and was analyzed using Hedonic scale. The distribution of the constitutional revealed that Soeum individuals accounts 53%, followed by ; Soyang 19%, Taeum 28%. For men, sorghum, potatoes, beef, scombroid, oyster, saury, octopus, codfish, walleye pollack, shrimp, croaker, pineapple, eggplant, leek, pumpkin, toenjang, draft beer, diluted liquor, coffee, cocoa were statistically different in food preference score by sasang constitution(p<0.05). For woman, chicken, pollack roe, a walleye pollack, persimmon, jujube, melon, citron, celery, burdock, vinegar, bean-paste soup, draft beer, ginseng, honey were statistically different in food preference score by sasang constitution(p<0.05). Association of sasang constitutions and food thought to be harmful or healthy to each constitution was analyzed. But Food preference score of food thought to be harmful or healthy were not statistically different in score among sasang constitutions. This results suggested that food intake patterns of subjects were associated with sasang constitutional food in parts.

  • 국내산 거봉, 캠벨, 머스켓 베일리 A, 쉐레단 품종을 이용하여 일반 적포도주와 스위트 와인을 제조하였으며, 사이벨 품종을 이용하여 백포도주, 네오머스켓 품종의 화이트 스위트 와인을 제조하였다. 본 실험의 결과 적포도주 제조에는 캠벨과 머스켓 베일리 A 품종이 타 품종과 비교해 적합한 산도 및 색도를 보였으나, 캠벨의 경우 당 함량이 다소 낮고 신 맛이 강한 결함이 있어 이를 위한 향후 가당 방법 및 포도재배 연구가 필요할 것으로 보인다. 백포도주 제조용 품종인 사이벨의 경우 산도가 매우 높아 발효에 적합하지 않았으며, 신맛의 증가로 인해 기호도가 떨어져 이를 보완할 수 있는 감산 연구가 요구된다. 기호도 조사 결과 품종 별로는 캠벨, 머스켓 베일리 A로 제조된 포도주의 기호도가 높게 나타났다. 향후 선별된 품종을 이용한 포도주의 고품질화 연구가 수행될 예정이며 축척된 제조 기술로 현지의 기술 지도를 통하여 제품의 산업화 및 상품화에 기여하고자 한다.

  • This study attempted to investigate the relationships between vegetable preference and physical status. The subjects were 127 kindergarten children living Kwang-ju. In this study, vegetable preference and health status of the children were investigated by response of thier mothers through questionnaires. Also, rate of dental caries and anthropometric measures were obtained by examination. The results are summarized as follows; 1) Anthropometric mesures of the subjects were higher than those of Korean standards for children. 2) The mean hedonic score for vegetable preference in subjects was 2.6. The difference in vegetable preference between male and femal was not significant except for a squash item. 3) Vegetable prefernce has a significant correlation with the def. tooth rate. Especially preference of spinach, wild sesame leaf, and cucumber were negatively related to the def. tooth rate. 4) Vegetable preference and anthropometric measures did not show any significant correlation. 5) Children who ate sweets for snacks frequently disliked vegetable and showed high rate of dental caries significantly(p<0.001). Children who had anorexia and constipation disliked vegetables significantly (p<0.01). Children who complained diarrhea symptom showed significant high rte of dental caries(p<0.01). From the results above, as the negative relationship between vegetable preference and def. tooth rate was found, many cooking methods of vegetables should be studied and nutrition education should be oriented to recommend an increased intake of vegetables by children.

  • Purpose: This study was conducted to understand the factors that affect the acceptance of gluten-free rice pasta samples prepared with added buckwheat, mungbean, and acorn starches, and to compare sensory characteristics of samples with those of 100% semolina pasta. Methods: Descriptive analysis of pasta was conducted by 12 trained panels. Acceptance test was carried out by 40 consumers using 7-point hedonic scale. Collected data was statistically analyzed by principal component analysis, and partial least squares regression analysis. Results: Quantitative descriptive analysis showed that increasing amount of buckwheat, mungbean, and acorn starches resulted in significant improvement in gluten-free rice pasta properties, especially texture, hardness, chewiness, roughness, and al dente with increasing amount of sample starches, and decreased adhesiveness. In acceptance test, appearance and texture of gluten-free rice pasta with mungbean starch were preferred than pasta made with 100% rice. Flavor and taste was preferred in pasta with buckwheat starch than other pasta samples. Rice pasta with 30% buckwheat starch showed the highest score in overall acceptance among rice samples. Conclusion: This study suggested that adding mungbean starch could improve texture of gluten-free pasta, and adding buckwheat starch would improve taste and flavor of gluten-free rice pasta.

  • This study was undertaken to examine the effect of sea tangle and sea mustard on physiochemical and sensory characteristics of cakes and the possibility commercialization of these functional cakes. The moisture contents of cakes prepared with sea tangle and sea mustard were higher than those of control, and a positive correlation between water holding capacity(WHC) and moisture contents was observed(r=0.836). As addition level of sea tangle and sea mustard was increased, volume of cakes were decreased, whereas hardness was increased slightly and color became deep. Hardness was strongly correlated to the volume of cakes(r= 0.914). Visual observation by photomicrography showed that, as addition level of sea mustard and sea tangle was increased, formation of air cells were prohibited and thus volume of cakes was decreased. The microstructural observation by scanning electron microscopy(SEM) showed that air cells of cakes were well developed up to 5% addition of sea tangle powder. As a result of the sensory evaluation for the cakes prepared with sea tangle and sea mustard, no significant difference was observed between control and those addition levels up to 5%. Flavor was proved to be the most important factor in determining overall acceptability and hedonic hardness score was inversely correlated to the objective hardness value(r= 0.853).
