With the advance of information communication technology, specifically the Internet technology, most schools have developed their own Web sites for the communication of diverse parties such as students, their parents, teachers, and others. In spite of the wide spread of school Web sites, their bulletin board systems are usually developed under the Web-boards for developing ordinary sites without reflecting educational environments. The purpose of this research is to develop the Web-board system for schools, which can be applied to construct adaptive school Web sites. This Web-board system is designed to reflect the educational environments as well as the user characteristics under the idea of customization and optimization. The main advantage of this Web-board system is that it can allow easy access to the system through user-friendly interface, and also promote interactions among users through their personalized Web pages.

Fake news threaten democratic elections and causes social conflicts, resulting in major damage. However, the concept of fake news is hard to define, as there is a saying, "News is not fake, fake is not news." Fake news, however, has irreversible characteristics that can not be recovered or reversed completely through post-punishment of economic and political benefits. It is also rapidly spreading in the early days. Therefore, it is very important to preemptively detect these types of articles and prevent their blind proliferation. The existing countermeasures are focused on reporting fake news, raising the level of punishment, and the media & academia to determine the authenticity of the news. Researchers are also trying to determine the authenticity by analyzing its contents. Apart from the contents of fake news, determining the behavioral characteristics of the promoters and its qualities can help identify the possibility of having fake news in advance. The online community has a fake news interception and response tradition through its long-standing community-based activities. As a result, I attempted to model the fake news by analyzing the affirmation-denial analysis and posting behavior by securing the web board crawl of the 'M community' bulletin board during the 2017 Korean presidential election period. Random forest algorithm deemed significant. The results of this research will help counteract fake news and focus on preemptive blocking through behavioral analysis rather than post-judgment after semantic analysis.

The purpose of this study is to examine factors influencing online product transformation focusing on benefits of online shopping and word of mouth. Generally, it has been known that buying search goods is more proper than experience goods in the online. However benefits of online shopping and word of mouth make product transformation from experience goods to search goods and the product transformation promote the purchase of experience goods online. We developed a conceptual model of online product transformation including benefits of online shopping(e.g. good price and convenience), online word of mouth (e.g. bulletin board and consumer reviews), and consumer characteristics (e.g. innovativeness and Internet usage). Also, we suggest several research propositions on online product transformation. The implications for marketing strategies of experience goods and furher research direction are suggested.

For the purpose of developing 'internet nutritional education program', this study analyzed the actual states of internet nutritional information of middle/high school students. Survey questionnaires were distributed from October 21, 2002 to October 26,2002 to a total of 564 students at three junior high schools and five senior high schools located in Seoul. The total number of questionnaires collected and used in our study was 479, which is 84.9% of the total questionnaires distributed. According to the survey results, we found significant difference in the nutritional information source between middle and high school students (p < 0.05) , and two groups responded that effective nutrition information material is 'electronic materials'. Most of the respondents connected with internet more than 1 times per day, but a large number of students were not experienced in using nutrition information of the internet. All groups were using nutrition information of the internet for homework, and satisfaction level of using nutrition information of the internet were an average. Effective methods for acquiring nutrition information of internet were 'educational game' for middle school students and 'bulletin board (Q & A)'for high school students. Moreover the factor analysis for internet nutritional information program's characteristics showed that 'instructing plans','contents of study & technical support','availability'and'interaction'were important considerations for developing internet nutritional information program. We found out through our analysis that was a strong need for a more practical and effective internet nutritional education program for middle and high school students.

Objectives: This study was conducted to investigate the status and need for nutrition and dietary life education among nutrition teachers at schools. These characteristics were analyzed if they were different between elementary schools and middle-high schools. Methods: Subjects were 151 nutrition teachers from 70 elementary schools, 41 middle schools and 40 high schools in 17 cities nationwide selected by two-stage stratified cluster sampling process. Survey questionnaires included the items on general characteristics, status and need assessment for nutrition and dietary life education. Chi-square test or t-test was used for data analysis by school groups. Results: Nutrition education was implemented at 65.7% of elementary schools and 51.9% of middle-high schools. Nutrition education was mainly performed in 'discretionary activities extracurricular activities' at elementary school and through 'newsletters, school homepage, foodservice bulletin board' at middle-high school (p<0.001). The most needed topic for nutrition education in nutrition teachers was 'healthy dietary habits and table manners' and this was not significantly different by school groups. Responses on adequate frequency (p<0.01), methods used for nutrition education (p<001), materials for nutrition education (p<0.001), information sources for nutrition education (p<0.001) were significantly different by school groups. Major tasks for activating nutrition education included 'securing the time for implementing nutrition education by reducing work loads' and 'developing standardized nutrition education materials' in schools. Conclusions: Nutrition education at schools might be activated by improving working conditions of nutrition teachers and developing the practical programs that reflect the needs of nutrition teachers.

The purpose of this study was to compare high-school students importance and performance toward restaurant service attributes for the marketing strategy development. Specific objectives were to: a) investigate restaurant patronage characteristics of high school students; b) identify the difference of patronage behavior among three types of restaurants; and c) analyze the importance and performance among three types of restaurants. A questionnaire was developed and hand-delivered to 400 students enrolled 9th grade in 4 different high schools in Seoul. A total of 320 students (80%) was responded to this study. The questionnaire was composed of two parts with 47 restaurant service attribute statements. Results of this study were as follows: 1. A total of 57% was female and 61% of respondents spent less than ￦5,000 per week on eating out. 2. The frequency of visiting the low-priced restaurant was 8.9 times per week. 3. Reasons for being a patronage to low- (${\geq}$￦2,000) and mid-priced ( <￦2,000 and ${\geq}$￦5,000) restaurants were hunger, appointment, and seeking favorites with freinds but the reason for high-priced (<￦5,000) restaurants was celebrating special days with parents. 4. The main source of information for selecting restaurants was family and friends, T.V. advertising, and bulletin board. 5. For the low-priced restaurants, food, hygiene, price, and location were rated as important; location, price, menu, and food were rated as satisfied. 6. For the mid-priced restaurants, hygiene, food, price, and menu were rated as important; food, hygiene, service, and menu were rated as satisfied. 7. For the high-priced restaurants, hygiene, food, and atmosphere were rated as important; food, hygiene, atmosphere, and menu were as satisfied. 8. According to paired t-test, the score gap between importance and performance was the highest in the hygiene attribute; differences were high with the low-priced and low with high-priced restaurants.

This study was conducted on the visitors regarding their usage and evaluation state of the interpretive media which is utilized as a self-guide environment interpretation for the purpose of accumulating basic data for the park management. A questionnaire survey was chosen and the 275 valid samples among them were analyzed. The socioeconomic and behavioral characteristics of the visitors turned out to be similar with the results from another visitor survey in the same site. Among those who used the interpretive media, the largest proportion(77%) used the information board resources of the park; the usage rate of interpretive labels of woody plants, interpretive signs of cultural assets, and LED signs were shown to be relatively high. The usage of park brochures, park web sites, visitor center exhibits, and bulletin boards were less than 40% each. Visitors were asked to evaluate the importance and performance of the nine interpretive medias using a Likert Scale whose value ranges from one to five. The result recorded averaged above 4, which proved that the respondents were perceiving the importance of all forms of interpretive media greatly. The performance of interpretive media was also evaluated as affirmative, except the visitor center exhibits.

Since the use of computer-mediated communication(CMC) systems has been steadily increasing in the teaching and learning environments, this study attempted to describe some of instructional strategies which can be employed as a medium of cooperative learning. One of the best way to conduct network-assisted instruction is to embed such a medium into cooperative learning. Network-assisted cooperative learning maximizes students' own learning and each other's learning using CMC, in which students can actively participate in their learning processes. The characteristics of CMC-transmission and search of information, interactivity, time and place independence-assist and enhance cooperative learning. In this study, the instructional strategies for cooperative learning via CMC are suggested as following: (1) choose the instructional goals, (2) structure positive interdependence, (3) select guidelines for grouping, (4) train cooperative skills to students, (5) set up the environments such as electronic bulletin-board, and (6) develop assessment tools. Finally, this study suggests that potentials of network-assisted cooperative learning can be realized by providing environments and thinking tools for cooperative learning. Appropriate theory and practice need to be followed up to support the cooperative learning systems.
