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 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.
Recently, International Telecommunication Union approved several methods for objective video quality measurements to be included in international standards. These methods are mainly developed to measure quality of digital video on professional CRT monitors. In this paper, we performed subjective tests in order to examine the applicability of the standard quality assessment methods for different display monitors such as common CRT, PDP, and LCD TV monitors as well as professional CRT monitors. Subjective testing on different display monitors shows that there exist relatively high correlations between the various display monitors, which indicates the standard quality assessment methods can be used on the display monitors under the given conditions of subjective duality assessment.
This retrospective study was conducted to investigate the growth of children and their care person's weaning behaviors and its relation between the growth and care person's attitude and behaviors about weaning. 272 subjects who had child under 2 years old at that time were randomly selected and answered the special questionnaire. Results were as follows: Using to Kaup index, 13.4% of children were estimated undernutrition, 60.6% were normal and 26.0% were estimated overnutrition. 97.6% of respondant (children's mother) were recognized the need of weaning and the first prurpose of weaning was supplement of nutrients, and the next one was to set up normal food habits. 39.1% of subjects were used normal adult foods as weaning food. 60.9% of subjects were proepared special foods (making at home or buying commercial weaning food). The socioeconomic status was major factor to influence mother's behaviors about weaning. Vegetable and meat gruel was the most commen weaning food and the next one was fruits puree and rice with soup. The correlationship were found between Kaup index and the score of mother's weaning behaviors, between momer's eductional level and the score of weanig behaviors. 96% of subjects wanted nutritional education about weaning. They wanted to know about desirable weaning process and correct informations of commercial weaning foods mid the convenient cooking methods. According to the difference of socioeconomic status subjects were wanted different eductional methods. Upper socioeconomic group wanted special books about weaning and lower class wanted to be educted through the mass media especially television programs.
Interest in companion screen services and high-definition television broadcasting services are rising along with the advanced of digital broadcasting communication technology. Not only providing good-quality broadcasting services in the main screen, but also creating added values of companion services in the secondary screen are important. In this paper we suggest a platform and a related authoring tool generating adaptive companion screen services according to user contexts. The Platform providing adaptive companion screen services based on user environment is designed and implemented for real service market. Proposed platform organizes a higher quality content service considering both user contexts and demands of service providers in real time, and the related authoring tool enables a novice user interface designer and service director to make adaptive user interfaces quickly and easily. We developed and simulated this platform in accordance with Korean UHD IBB standard which provides interactive service applications.
Currently, numerous (broadcasting) programs are being provided to viewers, which makes it hard for viewers to select a program to watch. Especially, surfing channels watching the program videos (which is the most general manner of searching a program) became a time consuming task of performing several tens of channel changes (a channel change takes about 0.7 second). In the paper, a data service for guiding programs using the multi-view of program videos is proposed. The data service allows viewers to navigate all program videos without channel changes. To implement the data service, a method for composing and transmitting multi-view videos with the meta data for handling each video of the multi-view has been devised and a Java API has been implemented to clip, resize, and display parts of the multi-view videos.
This study investigated vegetable buying behavior with the subjects of 250 housewives living in Gyeongju. According to the results, they usually buy the following vegetables by order of frequency: cucumbers (152 times), hot peppers (142 times), lettuce (140 times), and spinach (134 times). The intake frequency of fresh vegetables was 2 to 3 times per week as 50.0% responded so. All respondents considered freshness most importantly when buying vegetables regardless of age. They usually buy vegetables at traditional markets, and they think the markets are suitable for buying fresh vegetables regardless of age. And the result of analyzing relation among vegetable's vitamin C and the colors or kinds of vegetables selected by age was not statistically significant. About the improvements to use vegetables, respondents in the 20's chose useful information, ones in the 30's to 40's said diverse recipes, ones in the 50's went for the quality improvement, and ones in the 60's or more emphasized stable prices. They answered that they received nutrition information of vegetables mainly from TV or magazines, newspapers, and mass media whereas subjects in the 60's or more said they got it from neighbors or friends. For housewives to get and practice nutritional knowledge, it is necessary to develop recipes in consideration of nutritional balance and convenience and provide them with constant education of nutrition through lifelong education facilities.
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 whether elementary school parents' environmental literacy varied according to independent variables, to verify specific variables that affected their environmental literacy, and to analyze the correlation between elementary school students' and their parents' environmental literacy. Twelve elementary schools in Seoul and Gyeonggi-Do were chosen for purposive sampling. 342 questionnaires were used for analysis among the 350 questionnaires collected during the study, and their environmental literacy was measured through 55 questions consisted of 12 items for knowledge category, 22 for attitude category, 5 for behavior category, and 3 for skills category with 16 demographic variables. Statistical analysis was conducted on each of the variables that make up environmental literacy through mean t-test, F-distribution, Scheffe test, and Pearson correlation. The results of this study were as follows. (1) there is the difference according to age and career in parent's actual environmental literacy, but there is no difference in geneder, birthplace, residential type, religion and income. The parents in forties scored significantly higher than parents in thirties in subdomains of environmental skill and environmental interest in environmental literacy. And the parents with bachelor's degree scored significantly higher than parents with at least a high school diploma in subdomains of ecological knowledge, knowledge on environmental problems & issue, environmental skill and environmental behavior. (2) the most influential media on parents' environmental literacy is TV, then newspaper, internet and book follow. (3) the correlation between environmental crisis and environmental interest is the highest, but the mainly negative correlation is analysed between knowledge subdomains and other subdomains. (4) there is the correlation between elementary school students' and their parents' environmental literacy.
