This survey was carried out to Investigate the effect of the daily average nutrient intakes, self-consciousness of nutrition knowledge and health on the nutrition knowledge and food habits between college women and their own mothers, Questionnaires were completed by 214 college women who do major in nutrition and by 173 their mothers. The college women scored significantly higher than that of their mothers In the nutrition knowledge. And their mothers scored significantly higher than that of college women in the food habits. Most of the subjects belonged to 'Fair' food habit group, which was considered to be relatively good. The correlation of the scores between nutrition knowledge and food habits of the college women and their mothers was low. The daily average nutrient Intakes of all women were higher than the recommended dietary allowance except for that of Iron. There was a significant and negative correlation between the nutrition knowledge score and daily average nutrient intakes in college women. But there was not a significant correlation in the nutrient intakes in their mothers. And also there was a significant and positive correlation between food habits score in their mothers but there was not a significant correlation score in college women. The higher the women had a self-consciousness of health, the higher their mothers had a food habit score, but they had daily average nutrient intakes were lower than their daughter's(college women), And the women that had a self-consciousness of health were healthier, daily nutrient intakes in their own mothers were higher in the food habits scores than that of the college women. The main curriculum for a good food habits is that it is important that one has a responsible nutrition education. For the improvement of nutrition education program we should transmit the nutritional information through an effective mass media(i. e. Radio, TV, Newspaper).

Traditionally, news was consumed only through printed newspapers and broadcasting media, such as radio and television. However, the Internet has enabled people to consume news content online. Since most of online news content has been provided for free, it is not easy for news providers to charge the fixed subscription fee for online news content. Therefore, as an alternative strategy, some online news providers have tried to adopt the Pay-What-You-Want (PWYW) pricing model, which allows users (readers) to pay as much as they want after consuming news content. As this pricing model shows some possibility to grow and replace the unsuccessful monetization strategy of online news content, we therefore examined the comparative importance of seven heuristic attributes (i.e., article evaluation, article share, article comment, article information design, article length, writer SNS, and writer information) affecting readers' voluntary payment behavior through a conjoint analysis with 379 news articles collected from online news Website (i.e., Ohmynews.com) where the PWYW model has been working successfully. This study found that article share and article length are the most important factors which affect online news content users' voluntary payment. Finally, two major and eight minor propositions are suggested based on the findings of the study. This study would suggest guidelines for how to create online news content which induces much more voluntary payment.

This study examined awareness and information acquisition behavior regarding food hygiene and safety of university students to improve safe dietary practices and to get basic information to develop educational materials for food safety. It was conducted among 276 university students of Qingdao University and Liaocheng University in Shandong province, China through a self-administered questionnaire. Data were analyzed by SPSS Windows V.19.0. To describe characteristics of the respondents, frequency distributions were used. In addition, t test, one-way analysis of variance and Duncan's multiple range tests were conducted. The results were as follows: The respondents were generally interested in food hygiene and safety. However, the level of awareness regarding the food hygiene and safety system in China was not high. Almost forty-five percent of the respondents did not think that foods produced and distributed in China were safe. For the reasons for their distrust, most of the students replied that they did not trust the safety 'because of distrust for hygiene of the food process', followed by 'because of distrust for food distribution' and 'because of excess or illegal use of food additives on food process'. The respondents answered for the concern level toward food hygiene and safety foodborne disease threatened food safety the most, followed by heavy metal contamination and endocrine disruptors. The respondents acquired most information from electronic media including TV and radio. Most of the students wanted to participate in food hygiene and safety education. Finally, when they found hazardous or foreign materials in food the most frequent reaction was 'paying attention in the next purchase', followed by 'notifying others', and 'letting it go this time but never buying that product in the future'.

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.
