The purpose of this study was to investigate high school students' perceptions of biotechnology. Participants in this study were 9th and 10th grade students who were enrolled in high schools in Gyeonggi Province. The survey instrument used in this study was a 26-item questionnaire that was designed to measure students' perceptions regarding biotechnology. The study revealed that students' perceptions were positive toward the use of biotechnology on biological objects such as plant, grain and microbes. However, their perceptions were negative toward the use of biotechnology on humans and animals. Male students' perceptions were more positive than female students and there were significant differences between male and female students(p<.01). The study also revealed that male and female students had positive perceptions about the use of biotechnology in the development of beneficial products. However, male students' perceptions were more positive than female students(p<.01). Female students' perceptions were slightly more negative than males and they indicated a measure of caution in the development of beneficial products using biotechnology. Regarding the reliability of biotechnological information acquired from food companies, TV broadcasters, and entertainers, male and female students tended to be highly negative. Students perceived that environmental, religious and ethical issues did not affect the use of biotechnology when asked the effect of these factors on the use of biotechnology. They perceived that food safety and genetic factors of microbes did affect the use of biotechnology. Thus, the study findings suggest that teaching and learning strategies based on the differences of perceptions between male and female students of this study be established and the use of media, development of teaching method and materials be promoted in order to enhance student's performance in environmental education.

The purposes of this study were to determine what factors influence risk perceptions of females and males for milk produced using food-related biotechnology, to test whether risk perceptions or other factors influence self-protection actions and to estimate milk demand response in light of self-protection actions and other economic and demographic factors. The expected utility model was applied to explain the way consumers would take self-protection actions regarding risk perceptions and to drive milk demand. Telephone interviews were conducted and the data were collected from households(females=1,029, males=437) nationwide in the U.S. And the data were analyzed by Heckman two-step method using the software package LIMDEP. Risk perceptions were found to be influenced not by demographic factors but by outrage factors as well as attitudinal factors in both females and males, although some factors were different. In addition, risk perceptions and labeling availability were found to significantly influence self-protection actions in both groups. Furthermore, as an important concern in this study, self-protection action was found to significantly influence milk demand in only male group, implying a consistent behavior of males. Also milk price and household size were found to significantly influence milk demand in both groups. In fact, the results did demonstrate that labeling availability significantly influenced self-protection actions. That is, in markets where labeled laternatives were present, concerned consumers were more likely to self protect by substituting to these products. A policy implication of this result is that labeling food products produced using biotechnology enhances consumer choice. Hence, consumer could express a more accurate demand response and reduce the perceived food safety risk. Furthermore, education for females might be necessary to have a consistent behavior because self-protection action did not significantly influence female's milk demand, though they have greater risk perceptions than males have.

A study was undertaken to identify variations in the level of awareness, the information collection status, the level of acceptance, and the characteristics of information collection as it pertains to agricultural biotechnology based on information collection in the field of agricultural biotechnology. When examining subjective awareness, objective awareness, and interest in agricultural biotechnology, the results showed that the levels of all three variables were higher in cases where information exploration of agricultural biotechnology had been experienced. Among the participants who have experience in voluntarily collecting information about agricultural biotechnology, helpful information at a rate of 51.6% and harmful information at a rate of 42.0% were acquired, values much higher than the 37% and 30% corresponding rates for participants who had no experience. However, it was also found that harmful information has a significantly greater impact on perceptions of the future. The characteristics of information collection for agricultural biotechnology indicated that those with experience in voluntary information collection particularly preferred the Internet, whereas those without any experience showed little difference with regard to television and/or the internet. According to a survey of participants' interest areas in agricultural biotechnology and their level of information acquisition, "Safety of human bodies" was rated the top interest area at 36.9%, which also had the highest level of information acquisition at 30.0%. In providing and sharing information in the future, this is a direct reference to the priorities and proportions of each field.

The purpose of this study was to provide basic data for future research and suggest product development and market segmentation strategies by identifying the perceptions and consumption behaviors of vegetarians in each segment of the vegetarian market. According to food consumption value, a total of three market segments were derived, and the markets were named based on their characteristics, including 'environment and animal protection', 'multiple consideration' and 'low interest'. As a result of analyzing the perception of vegetarian-based food, "environment and animal protection" and "multiple consideration" presented positive perceptions of a vegetarian food product. Conversely, the group stating low interest expressed negative perceptions of the vegetarian food product. An analysis of the requirements for development for vegetarian-based foods products (eg. aquafaba), indicated that the development requirements for all products, except cultured and processed meats, were high.?Considerable demand was observed for vegetarian menus and vegetarian restaurants. As a result of the analysis on the necessity of the elements of the vegetarian restaurant menu, the subjects that stated "multiple consideration" had significantly higher awareness of issues related to vegetarian foods than others.

This study was conducted to analyse middle school students' perceptions of seafood as well as their eating experiences and favorite cooking methods for seafood. It also examined the frequency and use of seafood on school lunch menus. Questionnaires were distributed to 739 students in 5 middle schools in the Busan area. On a scale of 5.00, the average scores for perceptions toward seafood were as follows: 3.67 for health & nutrition, 3.53 for taste, 2.53 for smell, 2.77 for convenience. The male students had significantly_(p<0.05) higher perception scores for health & nutrition, taste, and smell than the female students. Among 38 types of seafoods, the highest percentages for eating experiences included seaweed_(99.2%), anchovies_(99.1%), fried fish paste_(98.6%), shrimp_(98.4%), crab_(98.2%), squid_(97.9%), sea mustard_(97.8%), mackerel_(97.7%), dried squid_(97.3%), and hair tail_(96.9%). However, the majority of students had eaten a limited amount of seafood. The degree of seafood intake at home was significantly_(p<0.01) higher than at school. The students' favorite cooking methods for seafood were in the order of grilling, stir-frying, steaming, deep-fat frying, and soup. However, the middle school lunch programs primarily served as soup, seasoning, stir-fried, braised, deep-fat fried, and grilled, respectively. The main reasons for leaving seafood on a plate were inconvenience due to the fishbones_(62.7%), tasteless_(45.4%), and disliking the smell_(35.7%). Improvements that students wanted for seafood on school lunch menus included removal of fishbone for convenience_(67.0%), taste_(52.0), and increased variety of seafood types_(38.2%).

This study identified consumer perceptions of biotechnology crops, provided the types and sources of information on agricultural biotech that consumers demand, and derived effective methods of providing agricultural biotech information by analyzing problems and improving the information available online regarding agricultural biotech. The analysis of sources of information on agricultural biotech showed that there were differences between preference and reliability. Respondents preferred the Internet (47.6%) and TV (36.3%), while they relied on TV (36.3%) the most, followed by the Internet (26.6%), and academic papers and technical books (23.1%). Only 27.1% of the respondents answered that they collect information on agricultural biotech proactively. The higher frequency of information collection indicated a higher satisfaction rate with the information that was being collected. Survey results for the websites that respondents preferred and relied on to collect information were that the most preferred websites were web portals (53.4%), while reliability rates across the various types of websites were relatively even: web portals (28.4%), academic institution websites (19.1%), and websites that provide professional information (18.2%). Surveys that examined factors that were important in choosing the websites for collecting information on biotech indicated that factors such as "Providing verified data and citation" and "Providing objectivity" were the most important. Examining the preferences and factors of preference by content type showed that the demand for visual aids, such as photos, tables, graphs, and videos, was high, and there were statistically significant differences between the factors of preference by content type.

An understanding of the knowledges, attitudes and perceptions of different populations is key for public health policy makers. Here, a survey was performed on knowledge, attitudes, and perceptions about malaria diagnosis, prevention, control, and treatment. The 407 survey participants included both uninfected inhabitants and patients from 2 cities (Gimpo- and Paju-si) of Northern Gyeonggi-do, known as high-risk areas for vivax malaria. We used community-based study design and non-probability sampling method using the primary data. Association between variables were tested using χ²-tests. In general, the information on malaria reported by the participants in this study was unsystematic and included inaccurate details. The knowledge of malaria symptoms, identified as headache, chills and fever, was high, but the surveyed community lacks knowledge of the specific medications used for malaria treatment, with a large number of respondents having no knowledge of any form of medication. Survey questions with high correct answer rates included questions about easy treatment of malaria in Korea, the high daytime activity of malaria-borne mosquitoes, and the infection risk posed by outdoor activities. However, a large portion of the respondents was unable to provide simple medical and biological information about the disease. This study aimed to comprehensively evaluate the knowledge, attitude, and practical behavior of the surveyed community with respect to malaria and the implications reported here could be applicable to other malaria endemic areas in Korea.

This study examines Korean representation of the biotechnology and psychological factors which can influence lay people's perception and attitude about biotechnology. Korean college students(N=433) and lay adults(N=90) whom had college education participated in the study. Participants of the study 1 were asked to list words which comes to mind when associate with the biotechnology in broad sense, and several specific applications in health, medicines, agriculture and research. Participants of the study 2 were asked to list possible benefits and costs of biotechnology and their specific applications. In study 3, Participants responded the questionnaires about perceptions and attitudes of biotechnology. Korean people associated the biotechnology with its costs or risks and benefits. Korean college students mainly got the informations of the biotechnology from TV, newspapers, or internet. They trusted the scientist group and NGO group on their judgements about the assessment of risk and benefit of the biotechnology. College students showed the positive attitude with the applications in medicines and negative attitude with the applications in agriculture and public using of individual's genetic information. The radicalism, sensitivity in behavioral activation system, and trust/cynicism were to be found as a significant influencing factor for interest/knowledge and behavioral intention in related with biotechnology. Finally, more extensive knowledge of biotechnology did not lead to greater acceptance of it.

Adolescents in Busan area were asked in a survey about their perception and attitudes towards fast food. Most respondents answered that they consume fast food once a month because it is fast, easily accessible and tasty. Although they perceived fast food as unhealthy and less nutritious, they were less aware of its effect on their health and nutritional status. The more knowledgeable respondents were about nutrition and health the less likely they were to choose fast food over other meals. However, respondents who had little or no knowledge about the nutritional factors of fast food accounted for 43.1%. As to their source of dietary information, students relied on themselves(31.0%), parents(20.5%) and mends(19.9%). The medium through which students got the most nutrition and health information was television(66.8%), followed by the Internet(36.7%) and magazines(29.7%). This study will enable educators to plan more effective strategies for improving the dietary knowledge of the adolescent population.
