The objective of this study is to investigate the satisfaction of elementary, middle and high school nutrition teachers in the Chungnam province concerning the free school food service. We surveyed satisfaction related to policies on school food service and the school food service center. Satisfaction on the school food service center was separated according to four dimensions; perception, food materials, operational system and service. Furthermore, we analyzed factors that affect satisfaction with the school food service center with a multiple regression model. First, satisfaction about the free school food service and dietary life education are higher than the total average of satisfaction with the policy about the school food service. Second, satisfaction about a variety of food materials and reasonable prices are lower than total average of satisfaction with the school food service center. Third, when more teachers have a high level of a positive perception and have higher satisfaction with the operational system of the school food service center, then they also subsequently display higher satisfaction with the school food service center. Therefore it is necessary to improve or make up for pricing and diversity on food materials by the school food service center.

This research has attempted to asses the relationship between trust management, the element of service discretion act, and the quality of the service. The research model and assumption have been set up based on such a theoretical research and the demonstrative analysis of the customer-encountering employees of five-star hotels in Seoul. The results of the study are as follows; First, the rationalization of management can be achieved by improving the service through having a command of trust management as a management strategy. Second, there has been significant differences between variables such as the degree of importance and accomplishment of trust management. And it tells us that it is necessary to improve the range of service discretion acts up to the level where the difference between importance and accomplishment is not in existence. Third, the variable changes according to demographic characteristics show us the necessity of providing individualized education by recognizing the differences among groups. Fourth, the trust management has a considerable effect on the quality of the service, and this indicates that the quality of the service can be improved through expanding the range of service discretion acts of customer-encountering employees.

The purpose of this study was to investigate the nutrient intake status and factors affecting the consumption of commercial staple food for Korean adults using the Korean National Health and Nutrition Examination Survey data from 2010 to 2014. As a result of analyzing the frequency of consumption of commercial staple food, in 27.578 subjects, 75.5% of them did not eat it once a day, 21.7% of the subjects consumed once a day, and more than two times showed 2.8%. According to the results of age, the higher the age, the higher the rate of not consuming commercial staple food, and the lower the age, the higher the rate of consumption of commercial staple food(p<0.0001). In addition, the rate of consumption of commercial staple food was higher in cities than in rural areas. The higher the education level, the higher the proportion of commercial staple food. The intake of rice, noodles, and bread increased significantly as the frequency of consumption of commercial staple foods increased. Protein, fat, riboflavin, and niacin showed significant differences with increasing frequency of commercial staple food in nutrient intakes(p<0.0001).

An edible wild perennial plant with extremely potent antimicrobial activity was found and identified as apiifolia Virgin's Bower (Clematis apiifolia DC) which is easily found around wet wildernesses. Fresh fruit extract of C. apiifolia exhibited minimum inhibitory concentrations (MIC) in the vicinity of 0.1% against various yeasts and of less than or equal to 0.4% for non-lactic acid bacteria. MICs against lactic acid bacteria were about 2.0%. The antimicrobial activity of C. apiifolia fruit was even more potent than that of garlic which has been known for its potent antimicrobial activity. The principal antimicrobial compound of fruit extract of C. apiifolia was isolated and identified by high performance liquid chromatography and gas chromatography as protoanemonin (a gamma lactone of 4-hydroxy-2,4-pentadienoic acid). The antimicrobial activity of C. apiifolia was stable at high temperatures, and the activity was maintained after heating at $121^{\circ}C$ for 10 min. The antimicrobial compound of C. apiifolia was supposed to inhibit microorganisms by reacting with sulfhydryl groups of cellular proteins.

A travel destination offers a form of novelty to the traveler since it can provide experiences that are not of the everyday variety. Therefore, a search for novelty is important as a motivation factor when planning leisure trips and vacation activities and to identify travel market segments. This study aimed to examine the differences in demographic characteristics, travel style, and preferred food-related activities in accordance with the level of tourists' novelty seeking. This study investigated potential tourists using a self-administered questionnaire survey, which resulted in 300 usable questionnaires. The respondents of this study were classified into two groups according to their level of novelty seeking: Active novelty-seeking group and Passive novelty-seeking group. These two groups were significantly different with respect to demographic characteristics, travel style, and preference of food-related-activity experience. The results show that the Active novelty-seeking group tended to have a higher proportion of females and specialized jobs, a higher level of monthly income and education, more frequent travel, and preference for food-related activity experience than other groups. The result of this study will be helpful for the tourist industry, which needs to develop culinary and food-related experience tour programs and travel market segments.

This study considered network quotient (NQ) of deluxe hotel employees and schematized characteristic attributes of being selected by employees with image through correspondence analysis in terms of cognition degree. Self-administrated questionnaires were completed by employees (292 samples) and data were analysed by frequency, t-test, one-way ANOVA, reliability and correspondence analysis. First, the hotel employees indicated the high average value in "participating in special education or seminar for improving ability ($3.85{\pm}0.76$). Second, as a result of analyzing difference according to gender, the average value in men was higher than in women. It was indicated that the higher age and career lead to a rise even in the average value of relationship index. Third, in consequence of carrying out correspondence analysis in order to prepare image map according to cognition level on relationship index in hotel employees, the measurement item that is placed in the closest distance to the response as saying of not so very was the response as saying of "having a lunch (dinner) engagement twice or three times a week."

The purpose of this study is to make profits and enhance national competitiveness through the globalization of Korean food. For this purpose, this study analyzed the certificate of qualification for Korean cooking technicians in the field of technical cooking. The results of presenting the perception, motivation for acquisition, and improvement measures of the Korean cooking certificate are as follows. First, as for the perception, if Korean cooking technicians acquire the certificate, they are acknowledged to acquire the qualifications and basic technology as licensed cooks in Korean food; however, they cannot practically execute cooking affairs. They cannot receive additional marks in time of employment. Getting the special education in cooking schools is helpful to acquiring the certificate. Second, the motivation for acquisition results from its advantage over other types of business, and a hope for running Korean food restaurants. Third, the improvement measures cover changing examination contents to be utilized in practical affairs, improving cooking methods, fair evaluation, and considering excessive technicians not to depreciate the value of the certificate.
