A survey was conducted to investigate consciousness of middle and high school students unsing fast food restaurants in Kwang-ju, from July 20 to August 20 in 1993. The results are follows; 1. There are many motives which drive students into fast food restaurants. Among those are its convenience as a place of meeting friends, pleasant and clean environment for eating, no time limit of staying there, hygiene of dining equipment and table ware. 2.The majority of the students used the fast food restaurants between 12:00 and 14:00 pm. It shows that time does not influence much on using there, because they answered in high percent that they use at any time. 3. Student usually pay individually and in some cases their friends or parents pay the bill. 4. Major factor in fast food selection was their tastes, nexts, were proper price, nutrition, and so on, They prefer their home food to restaurants fast foods. 5. The most of students have positive response to make traditional Korean foods into fast foods. The students, in particular, emphasized for the development of traditional Korean foods ; Sikhae and Sujonggwa(beverage), Docbokki, Japchae, kinds of rice cake and Jun. 6. Students suggested to be better fast food service, such as lowering the price, increasing the portion size and developing fast foods from the traditional Korean foods.

The purpose of this study was to investigate the levels of risk perception characteristics for food risk elements using a psychometric paradigm from 298 university students in Yeungnam region, Korea, by a self-administered questionnaire. The respondents showed the highest level of risk concern about radioactive contaminated foods and the lowest level about GM (genetically modified) foods. In the risk perception characteristics for food risk elements, they perceived radioactive contaminated foods as a catastrophic, worried, new, and uncontrollable risk. In addition, they regarded food additives and foodborne illness as a chronic, controllable, old, and scientifically and individually known risk. According to the results of the factor analysis for risk perception characteristics, dread and unknown were categorized. In the risk perception map, mad cow disease, heavy metal contaminated foods, and radioactive contaminated foods were considered as a dreaded and unknown risk, whereas pesticide residues and GM foods were perceived as a less dreaded and unknown risk. Additionally, food additives and foodborne illness were regarded as a less dreaded and known risk and endocrine disruptors and avian influenza as a dreaded and known risk. These results imply that risk perception characteristics of consumers should be considered to establish strategies for risk communication in food science.

This study aimed to estimate daily intake of anthocyanins and to identify major sources of anthocyanins in current Korean dietary patterns in order to implement dietary recommendations for the improvement of Korean health. Sixteen foods were selected based on the availability of food intake and reliable anthocyanin content. Food intake data from the Korea National Health and Nutrition Examination Survey 2014 and anthocyanin content data from earlier investigations were used to calculate the consumption of anthocyanins. Anthocyanin contents of 16 foods varied significantly and exhibited a range of 0~4,009 mg/100 g of fresh weight. Daily intake of anthocyanins was estimated to be 3.3 mg to 95.5 mg in Koreans. Of the 16 foods studied, the source contributing most to anthocyanin intake in the Korean population was plums (35.1%), followed by black beans (17.1%) and grapes (15.2%). These results indicate that major foods contributing to anthocyanin consumption in the Korean dietary pattern are fruits and grains.

This study was performed to investigate the antimicrobial effect of the Viscum album var. coloratum extracts against food-borne pathogens. First, the Viscum album var. coloratum was extracted with methanol at room temperature and the fractionation of the methanol extracts was carried out by using petroleum ether, chloroform, and ethyl acetate, and methanol, respectively. The antimicrobial activity of the Viscum album var. coloratum extracts was determined by using a paper disc method against food-borne pathogens and food spoilage bacteria. The petroleum ether extracts of Viscum album var. coloratum showed the highest antimicrobial activity against Bacillus cereus and Shigella dysenteriae. Synergistic effect in inhibition was observed when Viscum album var. coloratum extract was mixed with Perillae folium extract as compared with each extract alone. Finally, the growth inhibition curves were determined by using petroleum ether extracts of Viscum album var. coloratum against Bacillus cereus and Shigella dysenteriae. The petroleum ether extract of Viscum album var. coloratum had strong antimicrobial activity against Bacillus cereus at the concentration of 5,000 ppm. At this concentration, the growth of Bacillus cereus was retarded more than 24 hours and up to 12 hours for Shigella dysenteriae. In conclusion, the petroleum ether extracts of Viscum album var. coloratum inhibit efficiently Bacillus cereus and Shigella dysenteriae.

The purpose of this study was to measure the effects of service quality mediating the linkage among food and beverage price, restaurant image and value. A total of 273 questionnaires were completed. MANOVA, ANOVA and ANCOVA were used to measure the mediating effect of service quality on the relationships among food and beverage price, restaurant image, and value. The effects of food and beverage price and restaurant image on service quality and value were statistically significant. As expected, when food and beverage price and service quality were regressed on the value, the service quality was significant and the effect of the food and beverage price was reduced. Moreover, when restaurant image and service quality were regressed on the value, the restaurant image and service quality had a significant effects on value. The results demonstrated that service quality played a mediating role in the relationship between food and beverage price and value, and between restaurant image and value.

The present paper reviews the findings of different research studies on the effect of natural ingredients in the Japanese quail (Coturnix coturnix japonica) diet on carcass characteristics and meat quality. The results show a relationship between the type and concentration of ingredients used in diets and carcass characteristics and meat quality. The inclusion of medicinal herbs (thyme, black seed, and mint), plants (canola), seeds (chickpea), spices (cinnamon and coriander), worms (earthworms), bee products (propolis), phytochemicals (lycopene), and edible fungi (common mushrooms) in the diet improved carcass quality characteristics compared to the control diets (basal diets). The inclusion of medicinal herbs (spearmint and green tea), spices (cinnamon), vegetables (tomato), plants (verbena and canola), seeds (marijuana), and edible fungi (oyster mushrooms) improved meat quality. In conclusion, the use of ingredients of natural origin in the diet of Japanese quail improves carcass quality characteristics and meat quality.

Online shopping has been undergoing significant developments in the South Asian region in the last decade. Using a representative sample of Sri Lankan consumers, this study explored online food purchasing behavior in Sri Lanka, a developing nation and island in South Asia. Data were collected from 562 respondents from all nine provinces in Sri Lanka using an online survey. Consumer attitudes were evaluated using factor analysis, and factor scores were added as explanatory variables to the final model. An ordered logistic regression model was used to examine the impact of consumer demographics, economic variables, and consumer attitudes on online food purchases. Online food purchasing intensity was categorized into four groups that suited ordinal rankings: zero for never, low for rarely, medium for occasionally, and high for regularly. Results indicated that age, income, education, and living in urban areas affect the online food purchasing behavior of Sri Lankan consumers. In addition, trust, convenience, and attitudes toward price were powerful drivers of online food purchasing. The findings have a number of significant managerial ramifications for creating strategies to promote online food purchases in developing South Asian nations like Sri Lanka. Moreover, promoting online shopping could be a potential solution for traffic congestion, ultimately helping to mitigate the negative externalities associated with it, such as carbon emissions and air pollution.

The perceived performance of food management and the food utilization status of school food service managers in nine sectors of management in the Kyunggido area were evaluated[ED highlight - please ensure this is correct]. The results of this study revealed that 84.5% of the service managers used domestic food and $20{\sim}40%$ used organic food, with an average of 80% using one of these types of foods. In addition, the average use of pre-handling food varied widely when compared to other food items[ED highlight - very confusing, please ensure my changes do not alter your intended meaning] Additionally, most respondents used frozen food (72.0%), processed food (83.9%), and substitute food (53.4%), for the average of 20%,[ED highlight - I cannot infer your intended meaning here, what is an average of 20%? Please clarify]; however, 40.6% did not use any food substitutes. The most common reason given for using pre-handled[ED highlight - do you mean pre-packaged or pre-prepared? Please clarify] food was to save time (32.2%), whereas frozen foods were most often used to help with menu organization (37.5%). Additionally, the respondents most common reason for using processed food was its high acceptability (47.8%), while substitute foods were most often used due to non suitable foods beingreturned (75.3%). Among the varieties of food that were used, those that are easily obtained and cooked were used the most. Furthermore, the mean score for the perceived performance of food sanitary management was $4.51{\pm}0.425$ (based on the 5-point Likert scale). Finally, it was generally believed that the overall food management well executed, but that more active management of unsatisfactory food suppliers is required[ED highlight - please ensure my changes do not alter your intended meaning].

In Europe, 5 Lipoptena species have been recorded, including Lipoptena fortisetosa. This species, native to Asian countries, was described as a parasite of sika deer and its appearance in Europe dates back to more than 50 years ago. Lipoptena fortisetosa has been recently reported in Italy, sharing its hosts with Lipoptena cervi. A morpho-molecular approach was developed to determine the phylogenetic interrelationship of Italian and Asian CO1 haplotypes sequenced from Lipoptena fly individuals collected in Italy, and their DNA sequences were compared with conspecifics available in GenBank; morphological key-characters (terminalia) of L. fortisetosa were compared with the original description. Two haplotypes were recorded from Italy and assigned to L. cervi and L. fortisetosa, respectively. The latter was part of the monophyletic clade L. fortisetosa, along with 2 Central European and 2 Korean haplotypes (100% identical to one of the Korean haplotypes); moreover, Italian L. fortisetosa female terminalia were consistent with the original description of Asian individuals. Pending more in-depth investigations, this study provides a first answer to the hypothesis of the recent colonization of Italy by L. fortisetosa from Asia as we did not detect any obvious and stable morphological and molecular differences in specimens from the 2 geographical areas. The presence of the sika deer in Europe was retraced and the possible route traveled by the parasite from Asia and the eco-biological factors that may have enhanced its settlement are discussed.
