The objectives of this study was to explore the knowledge, attitudes, and perceptions of elementary school students towards trans fatty acids. In addition, the students' preferences and consumption frequencies of processed food items containing trans fats, as well as their food behaviors relating to snack consumption, were investigated. The study population consisted of students from seven provinces, including Seoul, Busan, Daegu, Kwangju, Gyungnam, Chungnam, and Kangwon. Two schools were selected in each province and one class was randomly chosen in each school. All students from the selected classes were surveyed onsite (N=951). The data were analyzed with chi-square tests and t-tests using SPSS/Windows (ver.15.0) program. The results showed that the students' knowledge levels toward trans fatty acid were very low, particularly on the production process of trans fats. The students perceived that trans fatty acids can cause health problems and should be consumed in low amounts. They also felt there is a need for a good nutrition education on trans fats. Furthermore, the students responded that their most preferred foods were in the order of breads, biscuits, and snacks. The most frequently consumed snack item among 2nd graders was biscuits and among 5th graders it was breads. It was also found that 90% of the students had snacks once a day, and of them, 58% prepared their own snacks. Based on this, we propose that students who allowed to choose their own snacks should be carefully educated on trans fatty acids to prevent excessive consumption of high trans fat foods.

The domestic swine industry is currently facing a threat due to the recent increase in pork imports. This study aims to determine what factors influence consumers' intention to consume imported pork and suggest measures to support the domestic pork industry. To achieve this, we analyzed data from the Korea Rural Economic Institute's Food Consumption Behavior Survey using a binary logistic regression model. The results revealed that a higher intention to consume imported pork is linked to a higher intention to consume imported rice, purchasing meat online, frequent purchases of HMR, and procuring U.S. beef, especially among urban residents. On the other hand, a lower intention to consume imported pork is associated with a higher awareness of animal welfare certification, frequently dining out, and older age. Based on these findings, we propose the following response measures for the domestic swine industry: implementing educational programs, marketing, and advertising specifically targeting urban residents to improve their perception of domestic agricultural products; enhancing price competitiveness through distribution optimization; and developing policies to promote the use of domestic pork as an ingredient in processed foods.

This study was conducted to investigate the consumption pattern and perception of traditional soy sauce and soybean paste products in male and female adults aged 19 and over in Seoul and Gyeonggi-do areas in order to promote the development of the products' industry. The survey was conducted between October 1 to October 15, 2011 among 294 male and female adults aged 19 years and over in Seoul and Gyeonggi-do areas. The gender distribution of the subjects was 33.3% males and 66.7% females. For a perception on traditional dietary life, the degree for enjoying meals with cooked rice as the staple food revealed that 32.3% of the subjects responded 'strongly agree'. The intake frequency of traditional soy sauce and soybean paste products in the subjects of the study showed that in the case of doenjang, 49.7% of the participants consumed it twice a week and 21.4% consumed it once a week. For gochujang, 59.9% consumed it twice a week and 19.0% consumed it once a week. The perception on the preparation method for traditional soy sauce and soybean paste products showed a low level for traditional soy sauce and soybean paste products. The reason for purchasing traditional foods showed that 77.6% of the subjects made purchases for convenience and 8.2% purchased it for its small package. For the subjects, the priority for purchasing traditional soy sauce and soybean paste products was as follows: in the first rank, ingredients & origin made up 33.7% and price comprised of 26.2% of the priority. Regarding satisfaction for soy sauce and soybean paste products in the market, the degree of satisfaction was high for gochujang. With regard to gender difference, female subjects showed a significantly lower satisfaction for cheonggukjang and kuk-ganjang, and a significantly higher satisfaction for chin-ganjang, compared to the male subjects. The results of the study depicted that consumer's requirement was high for traditional soy sauce and soybean paste products in the market, particularly for the safety of the products in the market. Consumer satisfaction was relatively positive yet, some efforts are needed in order to improve the quality of cheonggukjang and kuk-ganjang.
Purpose: The goal of this study was to examine body image satisfaction and perception according to weight status, and to investigate those associations with dietary habits and nutritional status among preadolescent children. Methods: Body image and dietary habits and intake were assessed in 134 elementary school students in grade 4. Children were categorized according to normal and overweight or obese groups. Figure rating scales were used to assess body image perception (identification of perceived current body size) and dissatisfaction (difference between perceived current body size and ideal body image). Results: There were sex differences in body image perceptions. Normal-weight girls, overweight or obese girls and boys were more likely to desire a leaner body size than their perceived body size compared with normal-weight boys. Body image satisfaction and perception showed an association with weight status. More overweight or obese children indicated dissatisfaction or underestimation of body image than normal-weight children. Children with body image dissatisfaction due to heavier perceived body size than ideal body image showed lower frequencies of consumption of meals and vegetables, compared to those who were satisfied with their body image. Children who underestimated their body image were more likely to have a lower frequency of breakfast and meal regularity and a higher frequency of eating out of home or food deliveries than those with accurate body image perception. In addition, body image underestimation showed an association with lower intakes of protein, dietary fiber and calcium, and the higher percentage of calories derived from fat. Conclusion: Body image dissatisfaction as well as underestimation in children before puberty showed an association with overweight or obesity, and was also related to unhealthy dietary habits. These findings highlight the importance of accurate perception and satisfaction with body image in preadolescent children in order to prevent development of obesity in adolescents and adults.
Advance of the Internet environment is applied not only to information search but also to the area of consumption behavior. Current research analyzes online use behavior and online information search of consumers in terms of users' perception. With the result of the research, it is noticed that promotion focus brings broader variation of information use behavior, and utilitarian value has a beneficial impact on the online exploratory information search. In addition, it is revealed that the more exploratory the information search is, the wider the range of online shopping information search is. Finally, people who have utilitarian shopping value showed more exploratory behavior in online search, especially for the search of informational products, than those who have hedonic shopping value. Present research is believed to improve practical influence of consumers' personality on online use behavior when customers purchase search products online. As a result, it would contribute to consumer research and marketing held online.
Review of the global change in various energy usages and resulting environmental impacts were made in terms of population increase, economic development and energy consumption. Greater use of fossil fuels in past couple of centuries give rise to acid rain and gradual climate changes mainly due to Green House inducing gases emissions from fossil fuel combustion. In view of the forthcoming Kyoto conference in December, various alternative options were assessed. To cope with rapidly developing robust Korean economy, the alternative energy options for the sustainable development in 21st Century would be the wider use of Nuclear Energy in parallel with constrained use of fossil fuel and renewable energy development. However there are many hurdles to overcome. One of the most important element is to improve public acceptability of those alternatives. Since public acceptance depend heavily upon individual perception on specific energy technology applications, the basic energy technologies education from primary up to high school education and the related curriculum organization is important. The suggested improvement in education for Nuclear Energy Application was made on the basis of advanced industrial countries with substantial Nuclear Energy Application programs.
The effects of a four-week weight control program including nutrition, exercise, behavior modification and meditation were studied in 15 obese children who resided in the Chuncheon area. There were no differences in anthropometric value, health perception, self-esteem and nutrition knowledge before and after the nutrition education program. Food behavior significantly improved after the program, especially in the area of binge eating (p〈0.05). Consumption of ramyon and fried chicken significantly decreased (p〈0.05). These results showed that short-term nutrition education programs did not do enough to change the anthroppometric value of study subject. These results suggest that it is necessary to include parents in nutrition education programs for greater effectiveness. And there is a need to develop an apply systematic nutrition education programs to reduce the weight of obese children.
