The purpose of this study was to analyze University student’s dietary behavior for processed foods and recognition on food nutrition labelling according to the degree of health concern. For this study, 302 University students in Gyeonggi region was surveyed by questionnaire from May in 2016 and it included the questions about general matters, dietary behavior on processed foods, and the food nutrition label system. It was analysed by SPSS win 23.0 program. And the results are as follows. According to the result of the factor analysis, the preference of processed foods were showed 3.21~3.97. There were significant differences in milk and milk products preference according to health concern (p<0.05). Also frequency of processed foods was shown significant differences in milk and milk products, noodles, beverage, and fast food (p<0.05), whereas no significant differences were found in meat products, snack, bread and frozen food (p>0.05). Also, the processed food purchase consideration according to health concern was shown significant differences in nutrition, origin, manufacturing company (p<0.05), whereas no significant differences were found in taste, price, exterior, brand, and shelf life (p>0.05). Thus, it is necessary to do continuing public relations and to provide more opportunities for nutrition education so that the University students may obtain right dietary behavior on processed foods and the system of food nutrition indication be established properly.

With the interest on operational efficiency due to the rapid growth of food material distribution industry and food service industry, the study adopts DEA (Data Envelopment Analysis) model and examines to measure the technological, pure technical and scale efficiency those companies engaging in the food material distribution and food service business. As a result of analysis, the companies operating integrated business have relatively higher efficiency than those operating only food material distribution or food service companies while the result indicates that three efficiencies don’t have significant difference depending on whether affiliated companies or not. In the results from the measuring by DEA.

The purpose of this study was to survey the perception and preference for Korean food among Chinese students residing in Korea (Chinese foreign students, N=69) and China (Chinese-locals, N=98). A total of 76.8% of Chinese foreign students and 70.4% of Chinese-locals had ever eaten Korean food in China before visiting Korea, and motivation to try Korean food at first was ‘easy access to Korean food restaurants’ (Chinese foreign students 38.6%, Chinese-locals 44.9%). The most important factors in selecting Korean food were ‘taste’ and ‘price’ (Chinese foreign students 72.7% and 18.2%, Chineselocals 59.1% and 22.7%, respectively), and needed improvements for Korean food were ‘spicy and salty taste’ and ‘nutritional aspect’ (Chinese foreign students 54.5% and 25.8%, Chinese-locals 33.3% and 36.4%, p<0.05). The scores for perception of Korean food were significantly lower in Chinese-locals (2.99) than in Chinese foreign students (3.31)(p<0.001). Chinese foreign students preferred Bulgogi (20.5%), Neobiani (20.1%), and Galbijjim (17.9%), whereas Chinese-locals preferred Bulgogi (16.1%), Gimbap (16.1%), and Samgyetang (15.2%) (p<0.001). The most preferred condiment was ‘Garlic’ (18.0%) in Chinese foreign students, and ‘Red pepper powder’ (16.4%) in Chinese-locals. The results of the study can be used as a foundation to prepare a globalization strategy for Korean Food.

The purposes of this study are to develop a chitosan suspension for the carbon dioxide (CO2) concentration indication of packaged food and to investigate the changes in the CO2 indication corresponding to 2-amino-2-methylpropan- 1-ol (AMP) or 2-aminoethanol (monoethanolamine, MEA) addition. Chitosan suspension was prepared by adding chitosan (0.1, 0.2, and 0.4%) to distilled water and subsequently the pH of the suspension was adjusted to 7.0 after the addition of AMP or MEA. Changes in the pH and the turbidity of the chitosan suspension were measured over time under exposure in a normal atmosphere or 100% carbon dioxide environment. The pH of the chitosan suspension exposed at 100% carbon dioxide environment decreased rapidly up to approximately 6.3 in the initial CO2 exposure. The transmittance values of 0.1 and 0.2% chitosan suspensions with 5% AMP increased from 32 to 99% and from 19 to 86%, respectively. The addition of 5% AMP improved the visual indication performance of the chitosan suspension since it increased significantly the width of the transmittance value before and after CO2 exposure. The chitosan suspension with AMP has a potential to be used as a quality indicator of the packaged foods which produce carbon dioxide during storage and distribution.

In recent years, ethical consumption has been attracting attention in Japan. Ethical products cover various issues, such as protection of the global environment, sustainability of resources, and protection of producers. Because the specification of such issues is difficult, previous studies often analyzed only one phenomenon. Several studies have attempted to examine the buying behavior of consumers of organic food products, based on Ajzen’s (1991) theory of planned behavior (TPB) (Sparks and Shepherd, 1992; Arvola et al., 2007; Chen, 2007, Lodorfos and Dennis, 2008). The TPB considers intention as a function of three principle determinants: attitude toward behavior, subjective norm, and perceived behavioral control. Regarding ethical food consumption, moral norms are individual value judgments connected to a specific behavior and its outcome (Manstead, 1999). A comprehensive model based on ethical issues for various products is required. Prior research highlights the consensus that targeting females in ethical consumption will have a greater chance of success (Roberts, 1996; Mainieri et al., 1997; De Pelsmacker et al., 2005). We propose three hypotheses to explain gender difference in consuming ethical food products. The aim of this study is to analyze the purchase behavior of consumers of ethical food products and to examine how consumers differ by gender in terms of the ethical issues. This study adopted organic vegetables, fair trade products, products certified by the Rainforest Alliance, free-range eggs, and fish certified by the Aquaculture Stewardship Council as ethical food products. These food products are associated with different ethical issues, and thus, we define ethical issues as “ethical attitude” for each product. For example, the ethical attitude of free-range eggs is included in the following categories (Table 1): environment, which means the protection of the global environment; health, which refers to the health of consumers; animal, which means the welfare of animals and the sustainability of resources; and farmer/aquaculturist, which means protecting farmers or aquaculturists

The objective of this study is to examine the effect of food scandals on trust towards the corporate brand and purchase intention in Japan. Drawing on Mayer, Davis and Schoorman’s Model of Organizational Trust (1995) this study explores the effects of perceived trustworthiness, trust, and perceived risk on a consumer’s intention to purchase. In Japan, consumers were outraged when some top hotels and department stores were found to have mislabeled foods, selling cheaper alternatives instead of the expensive foods offered on the menu and using expired products (Grace, 2007; Japan Today, 2013; Kageyama, 2007; Onishi, 2007; Spitzer, 2013). The various food scandals have led to product shunning, fear, distrust and suspicion among consumers (Garretson & Burton, 2000; Niewczas, 2014; Smith & Riethmuller, 1999; Yeung & Morris, 2001). Thus this research was conducted to identify the influence of food scandals involving well-established Japanese supermarkets on consumer trust and risk perception. The influence of culture in shaping purchase intention was also explored. Trust itself is a concept that is elusive with myriad definitions ranging from Luhmann’s (1979) sociological theory of trust that looks as trust being a function of high perceived risk and experience to Deutsch (1973) who defines it as the willingness to be dependent on others in the belief that the other party will not disappoint intentionally. Luhmann (1979) argues that in order for trust to be apparent there has to be high-perceived risk. Various studies have also focused on trust being operational when there is risk‐taking behavior (Anderson & Narus, 1990; Canning & Hammer‐Llyod, 2007; Doney & Canon, 1997; Morgan & Hunt, 1994). In the food sector, as consumers lose control over knowing about the food we eat due to the increasing complexity of the food system trust becomes an essential component. Consumers have to trust food producers ranging from farmers to food companies as well as the public authorities to ensure food safety, quality and adequate supply. Consumers display different and inconsistent reactions regarding food safety that affects the perception of quality and their willingness‐to‐pay (Berg, 2004; Brewer & Rojas, 2008).

Engagement has aroused tremendous interest in the marketing community, but studies examining engagement with luxury brands are absent. This study investigates whether luxury stores can use food to drive engagement with different customer segments. The results have important managerial implications and further our understanding of the behavioral drivers of (dis)engagement. The old marketing reality in which brands communicate with customers through one-way advertising messages is long gone (Campbell, Parent, Berthon, 2011). Now, it is not only brands that broadcast messages to customers, but customers can initiate or actively participate in conversations with brands. This customers’ participation in conversations with brands can have an effect on their and other customers’ purchase decisions. Therefore, brands are now focusing on using advertising to get customers engaged with them. Customer engagement has become a new way of describing brands’ relationships with customers. Scholars have offered many definitions of engagement. Some of them emphasize the psychological aspects of engagement (e.g., Calder Malthouse, and Schaedel, 2009; Mollen and Wilson, 2010), while others describe engagement in behavioral terms (e.g., Van Doorn et al., 2010; Verhoef et al., 2010). The most comprehensive definition of customer engagement was offered by Brodie et al. (2011: p. 790) who describe customer engagement as “a psychological state that occurs by virtue of interactive, co-creative customer experiences with a focal agent/object (e.g., a brand) in specific service relationships. It occurs under a specific set of context-dependent conditions generating differing customer engagement levels; and exists as a dynamic, iterative process within service relationships that co-creates value. Customer engagement plays a central role in a nomological network governing theoretical relationships in which other relational concepts (e.g., involvement, loyalty) are antecedents and/or consequences of iterative customer engagement processes. It is a multidimensional concept subject to a context- and/or stakeholder-specific expression of relevant cognitive, emotional and/or behavioral dimensions.” As both this definition and other definitions in the extant literature (e.g., Calder et al., 2009; O’Brien & Toms 2010).

Recent decades have seen a number of policies have been launched to promote information disclosure on food products marketed in developed countries. There has also been increasing efforts to promote healthy eating in developing economies (Cowburn & Stockley 2005). A good example appears in China, where, in an effort to improve health education, nutrition labels became mandatory under the Nutrition Labeling Act (NLA) since 2013. Additionally, food labeling regulations were issued by India, Mercosur members and South Africa. While nutritional labeling has received a lot of attention both in academia and from the press, there are some key gaps in the nutrition labeling literature. One issue of how standardized information requirements affect firm marketing responses (e.g., advertising levels. R&D investment, and corporate social responsibility programs) and performance has been understudied. Another clear gap in the literature is how nutritional labeling requirements affect developing economies.

Introduction Consumers throughout the world, including Asia, are showing increased concerns about food safety. Public policy, industry, and academic researchers are turning increased attention to the effects of food labeling requirements. General food labels provide information about serving size, servings per container, total calories per serving, calories from fat, and minimum daily nutritional value. Consumers must then use the food labeling information to make individual dietary choices. Thus it is appropriate for researchers to ask how consumers formulate product choices and evaluations according to food labeling information including calorie counts and standardized nutritional information (Ford et al. 1996; Keller et al. 1997; Roe, Levy, & Derby 1999). Long-term strategies are critically needed to find ways to protect public health and to assure food safety. Health practitioners and governmental regulators have increased their efforts to address the growing problem by sponsoring programs for food safety and by requiring nutritional labeling. In answer to the need for further research in food consumption behavior (RFC), this study was conducted to investigate how manufacturers might use consumers’ perceptions of risks and involvement for planning the most effective food labeling. Theoretical Framework To find ways to promote general and social marketing healthful consumer use of food labels (Lefebvre, 1988; McDermott, 2000), this study utilizes consumer segmentation techniques in which consumers are categorized according to psychological and demographic profiles (Slater, Kelly, & Thackeray, 2006). That is, they are segmented based on essential homogeneous responses (Forthofer, 2000; Kotler, 1971) and demographic characteristics, including age, gender, income and social class, although demographics may be less effective than psychological differences for predicting responses to health promotions (Lefebvre, 1988; Slater, 1991). The psychographics approach to consumer segmentation, derived from marketing techniques, selects variables that predict health behaviors; that is, consumers are segmented according to how they process communication channel properties and message features (Rimal & Adkins, 2003). By focusing on consumer segmentation we elucidate how consumers react to food labeling designed to promote health and food safety. Consumer segmentation should help us understand why consumers might reject risky unhealthful behaviors and adopt protective healthful behaviors (Slater, 2006). The risk perception attitude framework (Garretson & Burton, 2000; Rimal & Real 2003; Turner, Rimal, Morrison &, Kim, 2006) is a theoretical perspective for segmenting consumers based on their perceptions of risk and their beliefs about personal efficacy. According to the risk perception attitude framework, risk perceptions are usually insufficient to motivate behavior, but when high risk perceptions are coupled with strong efficacy beliefs, people are more motivated to engage in self-protective behaviors. Social cognitive theory and the extended parallel process model also support the importance of efficacy beliefs as moderating risk perception effects on self-protective behavior (Bandura 1986; Witte 1994). Using the risk perception attitude framework for purposes of this study, consumers are classified into four groups according to their risk perception and self-efficacy as indicated by their involvement in health concerns. 1) The "indifference" group comprises study participants who have low risk perceptions and low involvement; they believe they face few risks, lack control of their actions, and are thus not motivated to undertake protective behaviors. 2) The "responsive" group comprises study participants who have high risk perceptions and high involvement and thus are motivated to undertake extensive self-protective behaviors. 3) The "proactive" group comprises participants who have low risk perception but high involvement; they believe strongly in their personal abilities to take control, but perceive low risk and are thus not motivated to engage in self-protective behaviors. 4) The "avoidance" group comprises study participants who have high risk perceptions and low involvement; they are concerned about the need to counter risks but lack the self-efficacy and involvement to follow recommendations. Research Questions To examine the risk perception attitude framework in the context of research on food consumption behavior (RFC), three central research questions are posed: RQ1: How are consumers classified according to their level of perceived risk and involvement? RQ2: Do different consumer types show different attitudes toward paying higher prices for safer food and toward paying attention to food labels? RQ3: What factors influence consumer classifications? Methods Data for this study came from research on food consumption behavior (RFC) conducted by Korea Rural Economic Institute (KREI) in 2014. In 2013, the KREI began gathering data regarding food consumption behavior to help the food industry develop more efficient use of food resources. RFC data are appropriate because they include data about various consumption patterns regarding food lifestyles, purchases, and food safety. Specifically, RFC for this study, we gathered data for a stratified sampling of 6,311 consumers, 19 to 75-years-old, living in 16 metropolitan city-regions in South Korea. Table 1 shows general features of the research participants. Among the respondents, 44.2% were men; 55.8% were women; 10.7% were 19 to 25-years-old; 37.6% were high school graduates; 46.9% had lower than middle school graduation levels, 21.9% were college graduates, 2.3% had post-graduate levels, 1.1% were uneducated; 36.5% had average monthly family incomes of 200~399; 1.3% had the highest rate of 1000 and more; 1.0% had low to moderate interest in health; 42.8% reported that they bought food two or three times weekly; 0.7% reported buying food once a month. Respondents reported an average 3.93 regarding risk perceptions for food safety. Their reported average level of involvement was 3.32; average of intention to pay higher prices for safe food was 3.37, and their average likelihood of checking food labels was 3.15. Measurement To score education levels, the uneducated group = 1, less than middle school = 2, high school graduates = 3, college graduates = 4, and postgraduates = 5. A five-point Likert-type scale was used to measure participants’ interest in their health (1 = complete indifference to 5 = very much interested). Also a five-point Likert scale was used to measure perceived risk for twelve items related to food safety: foreign substances, pesticide residue, use of antibiotics in livestock and fish, natural toxicity, food additives, heavy metals, endocrine disruptors, bacterial contamination, livestock disease, GMO, irradiation, packing hazards, and allergens (1 = not concerned at all to 5 = very concerned). Involvement was measured for three questions regarding food origin, food materials, and eco-friendly products (1 = not concerned at all to 5 = very concerned). Intentions to pay higher prices for safe food and to check food labels were measured from 1 = not at all to 5 = very positive. Results Four consumer groups were classified according to their level of perceived risk and involvement. We followed previous RPA model studies (e.g., Sullivan et al., 2008; Jo & Yoo, 2011) and classified groups based on median perceived risk and involvement: (≥4.00) for high perceived risk, (<4.00) for low perceived risk, (≥3.333) for high involvement, and (< 3.33) for low involvement. The responsive group had high perceived risk and high involvement; the proactive group had low perceived risk and high involvement; the avoidance group had high perceived risk and low involvement; and the indifference group had low perceived risk and low involvement. Additionally, ANOVA with post-hoc Tukey test was conducted to examine the average difference among the four groups regarding their intentions to pay higher prices for safe food and to check food labels. Multinomial logit regression was performed to discover the factors that influence classification of consumer types. Classification of consumer types according to perceived risk and involvement Table 1 shows the consumer classifications according to the level of perceived risk and involvement: 1,198 participants, 21.8%, were in the indifference group with low perceived risk and low involvement; 1,254 participants, 22.8%, were in the proactive group with low perceived risk and high involvement; 1,125 participants, 20.5%, were in the avoidance group with high perceived risk and low involvement; 1,924 participants, 35.5%, were in the responsive group with high perceived risk and high involvement. Among the four groups, the responsive group had a statistically significant relatively high ratio: χ2 value for group classification was 79.695 (p <.001). Consumer classification differences in purchase intentions to pay higher prices for safe food and to check food labels Table 2 shows differences in intentions to pay higher prices for safe food and to check food labels. The proactive group showed the highest average intentions to pay higher prices for safe food at 3.52, followed by the responsive group at 3.51, the avoidance group at 3.25, and the indifference group at 3.16. The differences among the groups were statistically significant. A Tukey post-analysis showed that the high involvement group, in contrast with the low involvement group, showed higher average intentions to pay higher prices for safe food. Among the low involvement groups, those with high perceived risk had higher average intentions than those with low perceived risk. The responsive group showed the highest average intentions to check food labels at 3.44, followed by the proactive group at 3.43, the avoidance group at 2.74, and the indifference group at 2.27. The differences among the groups were statistically significant. A Tukey post-analysis showed that high involvement groups, in contrast with low involvement groups, showed higher average intentions to check food labels, but no difference was found according to the level of perceived risk. Influential factors of consumer segmentations Table 3 shows the results of examining the factors of gender, age, education, monthly average family income, and interest in health that are typical in consumer segments. Comparing all groups with the responsive group, the indifference group was most likely to comprise young women who had lower educational levels, lower monthly income, and less interest in health. The proactive group was most likely to be made up of men. The avoidance group was most likely to be made of young men who had lower educational levels, lower monthly incomes, and less interest in health. Discussion This study is an investigation of the theoretical framework of risk perception and involvement according to indifference, proactivity, responsiveness, or avoidance consumer segments. The study centrally indicates that the four risk perception–involvement framework groups differ in their perceptions of risk and the extent of their involvement. By revealing the importance of high involvement as a fruitful intervention strategy, the results suggest practical implications for public policymakers and marketers who strive to devise appropriate food labeling. Social cognitive theory has long stressed the importance of enhancing personal involvement (Bandura 1986). That insight can be applied to the risk perception attitude framework for identifying particular audiences who will respond to involvement-enhancing messages. Our findings suggest that a useful strategy in promoting change is to recognize that consumers will react differently according to their tendencies toward indifference, proactivity, responsiveness, or avoidance.

Despite consumers' growing support to preserve the environment, organic products business in emerging country such as Indonesia is still suffered from consumer’s low acceptance toward organic food. It is conceivable that some influencing factors are existed; as such consumers’ attitude cannot be translated into action. Through mixed methodology research, this study proposes an approach to integrate individual factors, which encompasses psychographic and demographic factors, into Technology Acceptance Model (TAM) to predict consumer acceptance toward organic food. Then, using Partial Least Square analysis, this study generates an extending TAM that could explain the role of those individual factors toward consumers’ acceptance on organic food.

With increasing income and education, requirements to product quality are getting higher in China. Specifically, people tend to nutrition and health now. Food safety has attracted increasing attention due to its importance. The nutrition claims on packaging became one of the most important standards to decide whether to buy. A great deal of research has focused on consumer responses (e.g., Hieke and Taylor 2012; Parker & Lehmann 2014; Shah et al. 2014) to the influx of product information to markets. Topics of research included the impact on consumers’ beliefs with regards to products (Ford et al. 2005), purchasing behavior (Nikolova and Inman 2015), and information processing behavior (Moorman 1990). The diversity of consumer responses is based on consumer differences (Moorman 1990), and health- and nutrition-related (HNR) claims (Choi et al. 2013). Although a great deal of research has addressed the influence of product information disclosure on the market, these studies have focused almost exclusively on developed economies. Going forward it is very likely that emerging markets will play a more important part in corporate strategic planning, as opposed to something considered after making plans for long developed markets. Thus, the impact of market information is likely to matter more and more to those global marketers operating in emerging markets. To fill the research gaps, we investigated how the existence and forms of nutrition claims affect the purchase intention of consumers in China. We explore the moderating role of consumer’s nutrition knowledge. We combine simulation experiment and questionnaire and design two experiments: Experiment 1 is about the existence of nutrition claims, we want to know how the existence of nutrition claims affects the purchase intention of consumers. Experiment 2 which is 2(health claims Vs function claims)×2 (promotion Vs prevention) test is to find out how the claim presentation forms impact the purchase intention of consumers. In experiment 1, we required the subjects to choose one setting randomly and fill in the questionnaires according to their choices. We collected 315 effective questionnaires of experiment 1and 156 effective questionnaires of experiment 2. The results show that: (1) The existence of nutrition claims affects the purchase intention of consumers. specifically, compared with the product without health claims, consumers tend to choose the one with health claims, and compared with the product without function claims, consumers tend to choose the one with health claims.(2)Nutrition knowledge plays a positively role. Nutrition knowledge can change the effect of the existence of health claims and function claims on purchase intention.(3) Consumer trust only plays a partly moderate role. The consumer trust can increase the effect of the existence of function claims but not health claims on purchase intention.(4)The forms of nutrition claims affect consumers purchase intention. Consumers tend to choose the product with promotion claims more than the one with prevention claims.(5) Nutrition knowledge plays a positively role, it can improve the effect of the forms of health claims on purchase intention. The more nutritional knowledge does consumers comprehend, the more sensitive to the product with promotion claims they are.(6)Consumer trust also plays a positively role. The higher Consumer trust does consumers maintain, the more sensitive to the product with promotion claims they are.

This study investigated the impacts of two different health claim regulatory systems, FoSHU (Foods for Specified Health Uses) and FFC (Foods with Function Claims) systems, in Japan on consumer evaluations of food products in terms of healthfulness. The FoSHU system was introduced in 1991 as an individual product approval system to allow product-specific health claims, while the FFC system was introduced lately in 2015 as a notification system like NLEA (Nutrition Labeling and Education Act) in the US. The latter system seems advantageous over the former in terms of shortening the product development period. However, the FoSHU system awards brand with a symbolic logo designed for FoSHU foods, whereas the FFC system does not. Which system leads to higher consumers’ healthfulness perceptions? The results of ANOVA showed that, if the health functions of the food product are not attributed to the product category, but to a specific food product brand, health claims have a strong impact on healthfulness. In contrast, if the health functions are attributed to the entire product category, health claims do not have a strong impact on healthfulness perception. In the latter cases, the FoSHU symbolic logo helps consumers to identify functional foods. Thus, in this study, it is suggested that, in Japan, the new US style health claim regulatory system is affective in the limited product categories. Public policy makers should recognize the important role of the symbolic logo for the previous system and consider introducing another logo to the new system.

This study examined psychological attitudes towards Japan’s food safety image when subjects were evaluated on their reactions to potential radioactive contamination of foods. Using a self-reporting questionnaire and functional MRI experiment we were able to verify that people demonstrated increased anxiety in the insular cortex of the brain.

This study aims to investigate the satisfactions with school food service for elementary and middle school parents. We surveyed parents about their concerns regarding food materials, the perception of free school food service, improvement of free school food service and satisfaction with the quality of school food service. The regions were classified into two categories according to the operation of a school food service center. The respondents with greater concern and cooperative purchase of food materials had higher satisfaction with the quality of school food service. It is interesting to note that school food service centers managed directly by the local government had higher satisfaction than those operated by private enterprises with respect to the quality of the school food service. The results of this study can contribute to the establishment of school food service and school food service center policies in the future.

The purpose of this study was to investigate the relations between HbA1c level and health risk factor. For analysis, 330 elderly women aged 65 years and over were recruited in Jeonla province, Korea. The subjects were classified into two groups according to their HbA1c level; the diabetic group (HbA1c level≥6.5%, n=68, 20.6%) and control group (HbA1c level< 6.5%, n=262, 79.4%). Demographic characteristics were collected, as well as information on physical measurements, blood tests for biochemical indicators, a health status and health-related life style, dietary behavior, favorite food groups, consumption frequency of food groups and nutrient intake. Educational level of the diabetic group was significantly lower than that of the control group. The height of the diabetic group was shorter, and percentage fat of the diabetic group was higher than those of the control group. In the diabetic group, the higher concentrations of creatinine and activity of alkaline phosphatase were found to be significantly unfavorable factors. Therefore, the diabetic group was assumed to be at risk of decreased liver and renal function. The self-rated health level of the diabetic group has a declining tendency, while the medicine intake was significantly higher than that of the control group, but there are no significant differences in visiting frequency of hospital and community health center. The distribution of physical activity showed a significant difference between the groups. Although there are no significant differences in nutrient intake, the diabetic group had relatively inferior nutrient intake of diet, especially vitamin C, as contrasted with the control group. In conclusion, the weight control and increasing physical activity may be effective in the prevention of the diabetes and continuous education and intervention by specialized nutritionists will be needed for diabetic patients. These results could be useful to plan effective strategies to increase the health-life expectancy and the prevention of the diabetes of Korean elderly people living in rural areas.

The objective of this study is to investigate the perception and satisfaction of elementary and middle school students on free school food service. We surveyed education related to school food service, concerns about food ingredients, perceptions of free school food service and satisfaction for the quality of the school food service. The investigation is classified into two groups, schools that operate as a food service center or those that do not. Those who are provided food ingredients by school food service centers are educated about the agricultural products’ country-of-origin and their environmentfriendly food service. The more individuals are educated of the foods’ county-of-origin and environment-friendly food service the more they will have a higher concern of the food materials and subsequently a higher satisfaction for the quality of school food service. School food service centers managed directly by the local government would probably receive higher satisfaction than those consigned to a private sector. The results of this study will be meaningful to establish policies on school food service and school food service centers.

음식물류폐기물의 에너지 잠재량은 2,206 천TOE 임에도 대부분 사료화와 퇴비화로 약 85.5%가 재활용 되고 있으며, 해당 시설에서 생산된 제품 중 사료화는 72%, 퇴비화는 61%가 무상판매 되고 있다. 이에 본 연구는 음식물류폐기물을 반탄화 반응을 이용하여 연료화하고자 한다. 하지만 음식 물류폐기물만 단독으로 연료화 할 경우 연료적 가치가 낮아짐을 예방하고자 하수슬러지를 일정 비율로 혼합하여 진행하였다. 음식물류폐기물과 하수슬러지의 혼합비율은 10:0, 8:2, 6:4, 5:5로 하였다. 실험 결과 혼합 비율에 상관없이 반응온도 240℃이상에서 함수율 10% 이하로 감소하는 것을 확인 할 수 있 었다. 고정탄소의 경우 반응온도가 높아질수록, 하수슬러지의 비율이 높아질수록 증가하였으며, 초기 1.1%에서 최대 약 36% 로(혼합비율 6:4, 반응온도 270℃) 측정 되었으며, 발열량의 경우 반응온도 24 0℃부터 고형연료제품기준인 3,000Kcal/Kg 이상에 만족하는 발열량을 나타내었으며, 초기시료보다 약 6 배 정도 증가한 발열량을 얻을 수 있었다. Van krevelen Diagram이 Lignite 범위까지 이동하였으며, 슬 러지 혼합비율이 높아질수록 높은 연료비와 5,500Kcal/kg 이하의 연소성지수를 얻을 수 있었다. 하수슬 러지 혼합 비율이 높아질수록 발열량은 감소하지만, 고정탄소 함량 증가, 연료비 개선 등으로 음식물류 폐기물만 단독 고형연료화 한 것 보다 연료로써의 품질이 좋아지는 것을 확인 할 수 있었다.

식품에서 대장균군을 효율적으로 분리하기 위해 대장균군 선택배지 5종: Chromocult Chromocult coliform agar (Merck), Hicrome coliform agar (Sigma), CHROMagar ECC, Brilliance E.coli/coliform medium (OXOID), endo agar (Merck)을 선별하여 식품 분리 대장균군 83종 및 표준균주 21종에 대해서 민감도와 특이도를 분석한 결과 Chromocult coliform agar와 HICrome coliform agar에서 94%도 민감도가 가장 높았으며, Brilliance E.coli/coliform medium는 93%, CHROMagar ECC는 92%, ENDO agar는 74%의 민감도를 나타냈다. Chromocult coliform agar와 HICrome coliform agar는 대장균군의 회수율도 높았다. 그러므로 Chromocult coliform agar와 HICrome coliform agar는 대장균군을 분리하는데 가장 효율적인 배지로 생각된다.

본 연구는 세계적으로 점점 애완 식품 시장이 발달하고 있음에 따라 천연물을 소재로 하여 치석, 치태를 감소시킬 수 있는 기능성 수제 간식을 개발하고 그것을 통하여 구강의 건강을 개선하고자 진행하였다. 연구에 사용된 개들은 주변 학우들에게 연구에 대하여 설명을 해주고 동의한 학우들의 개들에 통하여 진행하였다. 간식 급여 기간은 2016년 5월 11일 ~ 25일까지 2주간 급여를 진행하였고, 체중을 기준으로 급여하였다. 지표를 이용하여 치석, 치태의 축적도를 관능검사로 평가하였다. 상이한 대상을 통한 연구로 인하여 정확하지 못한 실험 결과를 초래 하였다. 이를 확인하기 위한 적절한 동물들의 사용과 재료에 대한 연구와 실험방법, 실험기간을 제대로 확립한다면 치석, 치태 감소에 좋은 새로운 소재라 생각한다.
