  • This study conducted surveys on perception and utilization of Korean soybean paste targeting 493 women from their 20s to 60s residing in Daegu. Most subjects married (75.3%), were part of a nuclear family (84.8%), had more than a high school diploma (95.8%), had a career (47.9%), lived in an apartment (68.4%), had a total household income of 5 million won or more (38.1%), and had monthly food expenses more than 0.5 million won and less than 1 million won (42.2%). Regarding perception, 'rich nutrition' was the most commonly held perception in subjects in their 60s (4.4), followed by 'good taste' in subjects in their 40s (4.3). Regarding reasons for consumption 'healthy' was highest in subjects in their 60s (47.3%) and 40s (45.6%) and 'delicious' in subjects in their 20s (56.1%). Regarding how to make it, subjects in their 60s responded 'know for sure' (57.1%), while only 2% of 20s responded the same. Subjects in their 50s and 60s had a higher ratio of answering 'know' while 20s and 30s 'don't know', For preparation methods, subjects in their 20s (53.1%) and 30s (41.4%) answered 'buy at the market', subjects in their 40s (68.9%) 'get from family or relatives' and subjects in their 60s (47.3%) 'make by one's own'. For preservation method, subjects in their 20s and 30s answered 'preserve in refrigerator', the 60s tend to answer 'preserve in jangdokdae'. Buying at the market was most common in subjects in their 20s (36.1%) and 30s (28.5%) and the reason was 'convenient' (39.6%). The place of purchase was 'in large supermarket or department store' (78.5%). For the future consumption pattern, 'increase in consumption of commercialized product (44.0%)', subjects in their 60s answered 'keep making at home' while subjects in their 30s and 40s answered 'keep making at home or buying product half and half'. According to the above study results, women living in Daegu region were aware of excellence of traditional soybean paste. However, due to changes in residential circumstance and lack of knowledge about the recipe, they did not make. They receive soybean paste t from family, relatives or bought in the market, which indicates the continuous decrease in home-made soybean paste. Therefore, due to the expanding social participation of women, the product market is expected to increase. I think it is important to develop traditional commercial soybean paste in the traditional way to improve the traditional flavors.

  • 2003년에 광우병 발생으로 수입 금지되었던 미국산 쇠고기는 2008년 한 미 FTA 체결로 인하여 전면 수입 개방되었고, 이는 국민들의 불안심리를 자극하여 정부와의 갈등을 야기시켰으며, 2008년 국내 최대 이슈가 되었다. 이러한 사회적 논란은 소비자들의 수입 쇠고기 및 한 육우의 소비를 감소시켰다. 따라서 본 연구는 쇠고기의 사용자 측면(일반 소비자)과 제공자의 측면(외식 예비 창업자)에서 미국산 쇠고기에 대한 수용 태도를 조사하고, 그에 따라서 쇠고기 소비량 변화에 대한 탐색적 연구를 실시하고자 하였고, 미국산 쇠고기에 대한 수용 태도는 소비자들의 불신과 두려움, 분노와 같은 부정적 감정으로 인한 태도를 측정하기 위해 이율배반이라는 개념을 도입하여 측정하였다. 그 결과, 미국산 쇠고기에 대한 이율배반적 수용 태도는 존재하는 것으로 나타났다. 일반 소비자는 미국산 쇠고기에 대해 자신은 먹지 않지만, 타인이 먹는 것은 괜찮다는 이율배반적인 수용 태도 B형에 동의할수록 쇠고기 소비량은 증가하는 것으로 나타났고, 외식 예비 창업자는 미국산 쇠고기에 대해 자신은 먹지만, 타인이 먹는 것은 걱정된다는 이율배반적 수용 태도 A형에 동의할수록 쇠고기 소비량은 감소하는 것으로 나타났다. 또한, 외식 예비 창업자는 미국을 신뢰할수록 이율배반적 수용 태도 A형에 대한 동의가 낮아지고, 일반 소비자는 미국을 신뢰할수록 이율배반적 수용 태도 B형에 대한 동의가 높아지는 것으로 나타났다.

  • The purpose of this study was to investigate how constructs of job embeddedness (fit, links and sacrifice) affected innovation-related behaviors. This study also investigated the relationship between innovation-related behaviors and turnover intention. The samples of this study were employees of Daegu City restaurants who visited the 2010 Daegu Food Tour Expo on October 7-10. A total of 302 questionnaires were analyzed with the statistical methods of factor analysis, reliability test, and covariance structural analysis. There were two findings of the research. First, we found that fits, links, and sacrifice were positively related to innovation-related behaviors. Second, we found that innovation-related behaviors were negatively related to turnover intention. Therefore, restaurant managers in Daegu City should pay attention to providing employee organization that helps them to first in, makes sure that they have lots of links with other employees, and bestows as many wage and fringe benefits as possible. Also, restaurant managers should reward the innovation-related behaviors of employees.

  • This study aimed to analyze the impact of importance and fulfillment(satisfaction) factors of menu quality on customers' intent of revisit of Japanese restaurants, so that it could provide information helpful to build up detailed marketing strategy and present considerations for management's higher sales amount and more efficient business results as well. Importance on menu quality scored higher level than fulfillment on the whole in Japanese restaurants. Notably, in regard to attributes of menu quality, it was found that respondents put higher stress on flavor, nutrition, cleanliness and freshness than anything else. In terms of IPA analysis on Japanese cuisine menu quality, it was noteworthy that the items with high importance but low fulfillment included menu price as an attribute for menu quality, although it was not shown in menu-specific items. In the survey on the associations between fulfillment(customer satisfaction) and intent of revisit, it was found that factors of customer satisfaction included 'trimness of dishes', 'information', 'appropriateness' and 'economic affordable' Out of these factors, it was noted that both 'trimness' and 'economic affordable' had significant effects on customer satisfaction at the significance level ranging from p<0.05 to p<0.001.

  • In this study, we examined the composition of catechins, theaflavins and alkaloids in leaves during processing to fermented black tea, which is produced by withering, roll breaking, and fermentation of Korean Yabukida tea plant. In addition, we determined the optimal conditions for the production of fermented black tea. The average moisture content in fresh leaves was 70.85%, which dropped to 3.07% in fermented black tea at the last stage of production. When the leaves were analyzed by HPLC, seven types of catechins, four types of theaflavins and three types of alkaloids were identified. The levels of catechins, theaflavins, and alkaloids were then evaluated after being processed into fermented tea. From these experiments, we found that the level of theaflavins, which determines the property of the tea, increased during fermentation. This effect resulted from the change in EGCG, ECG, EGC, EC during the process of fermentation. We also found that the maximal amount of theaflavins was created after 1-2 hours of fermentation. Thus, our results imply that the best condition for producing fermented black tea would be to ferment for 1-2 hours.

  • Purpose - The domestic franchise industry has made significant contributions to industry such as investment, employment, and community economy development, facilitating growth potential. The franchise industry provides management knowhow transfer between parent companies and franchisees as per contracts addressing use of business signs, franchisees' independent position, franchisor support, and royalties to be paid to the franchisors. However, many franchisors lack management knowhow and provide insufficient support because of poor control of franchisees and not having a systematic approach to support. This results in dissatisfied franchisees and failure to establish long-term relationships. Few studies have examined relational commitment and/or re-contract intention by support resources between franchisors and franchisees, despite a considerable output of theories and studies of the growth of the franchise industry. The purpose of this study, therefore, was to examine the effects of the ability to provide resources on relational commitments and re-contract intention, and to suggest causal relationships and implications. Research design, data, and methodology - The subject was domestic franchisors registered with the Association of Franchise with more than 50 franchisees. Franchisees under contract for 2 years and considering re-contract of their franchise 2 years later were used. The subjects totaled 300 franchisees in Seoul. A questionnaire survey was used to investigate the subject of franchisees' concessions during the 10 days from November 21, 2013 to November 30, 2013. After excluding 16 surveys with poor answers, 284 responses were finally used. Four areas and 44 questions were used. A nominal scale was used for four common characteristics questions including gender, ages, educational background, and franchise managing time. Questions regarding ability, relational commitment, and re-contract intention made use of a Likert 5-point scale. Data coding and data cleaning were used. SPSS 18.0 was used as follows. First, frequency analysis was done to investigate demographic characteristics. Second, exploratory factor analysis was done to verify validity of testing tools, and Cronbach's α coefficient was used to verify reliability. Third, correlation analysis and multiple regression analysis were done. An exploratory factor analysis was done to verify validity of concepts. A correlation analysis was done to test relationships between the variables, and multiple regression analysis was done to verify franchisor's ability, franchisees' relational commitment, and re-contract intention. Results - The following were the outcomes. First, store operation management, finance operation management, and human resource management affected the calculated bond. Second, store operation management and finance operation management affected the emotional bond. Third, store operation management, finance operation management, human resource management, and marketing management affected the prescriptive bond. Fourth, calculated bond and prescriptive bond had an effect on re-contract intention. Conclusions - As stated above, in franchise management, parent companies' offer and instruction of core competence to their franchisees as an information resource could improve the relational bond by helping them grow together through the resource sharing. Consequently, core competence factors were promoting factors that could improve franchisees' re-contract intention for a long time.

  • The present study was undertaken to evaluate the effect of Rhodiola sachalinensis root ethanol extract (RS), on the body weight, organ weight, plasma glucose and plasma lipid in diabetic rats caused by streptozotocin (STZ). The body weight decreased more slowly in the RS group than in the diabetic, and the food intake increased significantly in all diabetic groups. The food efficiency was very low in all diabetic groups, but increased significantly in the RS groups than diabetic control (p<0.05). In comparing the weight of organ, the weight of liver and kidney were increased in all diabetic groups than in the control, and decreased slightly in RS groups. The weight of heart and spleen were not different among all test groups. The glucose in serum was decreased significantly in the RS groups fed the RS for 4 weeks, compared to the diabetic control (p<0.05). Total cholesterol, triglyceride and atherogenic index (AI) in serum were significantly higher in diabetic control, compared to the normal (p<0.05), and decreased $16.7\%,\;18.3\%\;and\;45.0\%$, respectively, in the RS fed $300\;\cal{mg/kg}$ of RS. HDL-cholesterol was increased slightly more in the $RS-300\;\cal{mg/kg}$, compared to diabetic control. These findings suggest that RS treatment has protective effect in diabetes.
