The main purposes of this study are to know the contents and forms of impressions that the general public, and the consumerists and environmentalists have of irradiated food, and to know what information of irradiated food influences their impressions. Other purposes are to know what sources those impressions derive from, to know which media they have recently been exposed to and paid attention to irradiated food through, to know which sources they trust of information regarding irradiated food most greatly, and finally to suggest policies and strategies of communication in order to shed positive impressions of irradiated food on people. This study was conducted through the person-to-person interview survey toward 1,200 adults, and 150 consumerists and environmentalists in 1999. Adults are sampled nationally in South Korea. Only 8.7% of the general public have heard of irradiated food. Impressions of irradiated food that the general public mentioned most frequently are: harmful, insecure, negative, etc. The consumerists and environmentalists were found to have the most inaccurate knowledge of irradiated food. Television and newspaper were the major sources of impressions of, exposure to and focus of attention on irradiated food. Based on these results, we seem to devise methods to enhance impression of irradiated food by disseminating information of advantages and benefits that irradiation provides food with and to promote the fact that irradiation on food is totally irrelevant to being radioactive, danger of a nuclear power plant, genetically modifying food, etc.

This study aimed to assess the total sugar intake for Korean and to identify major food sources contributing to those food components. Korean adults aged over 20 years old from the Korean National Health and Nutrition Examination Survey (KNHANES) 2001 and 2002 were selected. The data were analyzed to obtain nationally and seasonally representative information on the health and nutritional status of the Korean. Forty food groups were used in identifying food sources of total sugar and energy intake. Total sugar contents of foods in the KNHANES data sets were estimated by food code matching technique with Release 18 of the USDA National Nutrient Database for Standard Reference. Sample weighted means, standard errors, and population percentages were calculated using SAS and SUDAAN. The mean total sugar intake of the Korean was 60.3g in 2001, 40.9g in spring 2002, 45.7g in summer 2002, and 52.1g in fall 2002, which were 30-44% of intake of US people. Fresh fruit was identified as the most significant food source for total sugar intake in Korean population in all age groups and all seasons. The next major food sources following fresh fruits were candy/jelly/syrup/honey, coffee/coffee caream, vegetables, Kimchi, soft drinks, milk, fruit juice, cookie/cracker/cake, and vegetable juice/grain juice, which showed similar results through the seasons. While carbonated soft drink was the most significant food sources for total sugar or added sugar intakes for US people. The total sugar intakes were significantly higher in women, higher educational level, and residing in metropolitan area. As intake of total sugar increased, intakes of protein, fiber, calcium, phosphorus, iron, Vit A, B1, B2, C, niacin showed significantly increased, while high intakes of added sugars showed low intakes of some micronutrients in the US people. Percentages of people who consumed nutrients below EAR were less in higher total sugar intake group than in lower intake group. From these results, we can conclude that the food consumption habits including the total sugar intake of Korean people seems relatively good so far. More reliable database of total sugar and added sugar composition tables in public domain should be established in the future, and also more researches about total sugar and added sugar for Koreans should be continued.

Background: Korean wild boars (Sus scrofa coreanus Heude), because of their adaptability, are a widespread large mammal; however, they sometimes cause problems by invading farms and eating the crops, creating insufficiencies of some foods in South Korea. To understand the diet composition of Korean wild boars according to sex and body size, we collected their feces from Mt. Jeombongsan, Seoraksan National Park, South Korea. The sizes of fecal samples were measured, and genomic DNA was extracted from the samples. We amplified specific loci targeting plants (rbcL and trnL) and animals (COI) to detect the food sources of this omnivore and amplified the ZF and SRY regions to determine the sex. Results: In the wild boar feces, Rosaceae and Bryophyte were the most frequently detected plant food sources at the family level and Diptera and Haplotaxida were the most frequently detected animal food sources at the order level. As a result of sex determination, the sex ratio of wild boars collected in the Mt. Jeombongsan area was approximately 1:1. Our result suggested that there is no significant difference between the diet composition of male and female boars. Based on the average cross-sectional area of the feces, the top 25% were classified into the large body size group and the bottom 25% were classified into the small body size group. The large body size group mainly preferred Actinidiaceae, and the small body size group most frequently consumed Fagaceae. The diet of the large body size group was more diverse than the small body size group. Conclusions: Our results showed that the wild boars preferred Rosaceae, especially Sanguisorba and Filipendula, as plant food sources, and Diptera and Coleoptera of Insecta as animal food sources. Based on the results, the dietary preferences of wild boar appear to be distinguished by not their sex but their body size. Our study could help to elucidate the feeding ecology and population structure of wild boar, as well as address conservation and management issues.

This study investigated the effects and interrelationship on sensual behavior and wine information sources in selection attributes of wine. Selection attributes of wine were categorized into four variables: sensual behavior, recommend information, label information, and wine information. The study showed that for sensual behavior variable, "taste" was the most influential item as compared to "food harmony", "mood harmony" and "partner's choice". For recommendation information, label information and wine information, "specialist", "grape varieties" and "brand" had the most significant effects. The study performed factor analysis on sensual behavior and wine information sources. The cumulative variance was 74.197%, implying that all four variables incorporated appropriate items. In the reliability analysis, all four variables showed Cronbach's ${\alpha}$ values above 0.6. In the analysis of the causal relations using a structural model, the effects of customers' sensual behavior on wine information sources was further investigated. The model verified that taste, food harmony, mood harmony and partner's choice, which are items of sensual behavior, had significant impacts when choosing wine. Sensual behavior influenced all wine information sources, which customers utilize in decision-making. Among these sources, sensual behavior had the biggest effects on recommendation information, followed by wine information and label information.

Food/nutrition related views, beliefs, attitudes, and behaviors were investigated for three hundred randomly selected men and women, aged 20-60 years, residing in Seoul metropolitan area. Food/nutrition views, attitudes, and beliefs were found to vary greatly between groups of different age, sex, education and income level. Adults of 20-35 years of age showed significantly less strong views about keeping traditional food habits, while exhibiting a significantly high level of acceptance towards the use of convenience foods as compared to the adults aged 36 years or older. Food safety was found to be a major concern to most of the subjects accounting 69.7% for pesticides residues in fresh produce items, 94.7% for food additives in processed food, and 56.3% for food poisoning in foods eaten outside of the home. Male adults aged 45 years or older showed a strong tendency to rely on a few promotional food products for the maintenance of their health and for them the development and implementation of a sensible feed nutritin/health education program including a way to avoid nutrition quackery might be beneficial. Eighty percent of the subjects were found to read food labels with higher rates shown among young adults and females. Due to the virtual absence of nutrition labeling however, the percentage of subjects who idicated that they are looking for the information on nutrient content was low (<10%) compared to the rates for other informations such as date of manufacture(80.2%), expiration data(55.8%), ingredients(40.9), and additives(40.9%). Ninety one percent of the subjects indicated that they would like to see the sources for nutrition label the nutritional value of the foods. The top five most frequently (68.3%), food packages(50.7%), and radio(43.3%). Health professionals such as physicians, nurses, and nutritionists/dietitians were utilized less frequently as sources of nutrition information than lay sources, with reported rate of only 38%, 22%, and 0.7%, respectively. These results collectively suggest that strategies are to be developed to provide accurate nutrition information to adults.

Food handling practices playa key role in the prevalence of food-borne illness. Despite the fact that pregnant women are high risk groups for food-borne disease, little is known about their actual food handling practices at home. The objective of this study was to investigate behaviors regarding food-related hygienic practices of pregnant women. The questionnaire included questions in five major areas : personal hygiene ; adequate cooking ; avoiding cross contamination ; keeping food at safe temperatures ; and avoiding food from unsafe sources. Analysis of 488 questionnaires showed the respondents were unaware of the importance of safe food handling practices. Especially, pregnant women in our study should be encouraged to be careful about either risk of adequate cooking $(2.08\pm0.66)$ and keeping foods at safe temperatures $(2.69\pm0.63)$. Residency and number of children were consistent independent predictors of food handling behaviors. Previous food safety education also was found to have significant effect on food handling practices. TV news and newspapers were considered the most usable sources of food safety information by respondents. The behaviors identified in this study represent ones of particular importance for high-risk populations, like pregnant women. These population characteristics identified in this study could be incorporated in development of food safety educational programs for pregnant women being vulnerable on food-borne illness. Our results could have implications for the design of effective food safety educational efforts. This study indicates the need for continued and improved food safety education and for enforcing systematic food safety education for pregnant women.
