Since IMF relief financing, domestic economy has been rapidly cooled down. At this point that we predict an overall decrease of production and sale of industries, cooperative marketing activities of the whole dairy industry are required to promote milk consumption. As everyone knows, advertisement is only one of the various factors that affect sales. Other factors include price, distribution, package, promotion, and consumer's needs and taste. The objectives of the cooperative advertising campaign should be trial purchase of new consumers, maintenance of brand loyalty of existing consumers, more positive experience of using the product, and increase of frequency of purchase. Long term analysis is essential to making these kinds of behaviour changes. Also the objectives of the communication program should be a shift of awareness of milk from 'a basic health food for children' to a substitute to the beverage even for adults. To share database of consumers among companies, we need to find ways to use interactive on-line services, the internet, D.M. events and so on as well as the mass media. It should be a precondition that the main body of the cooperative advertisement includes the milk processing board, dairy companies, livestock cooperations, farmers and the Government. To assure continuous, activities to promote milk consumption, the Government should take the lead in legislating 'An enforcement ordinance for milk promotion and research', and seek complementary measures and support to establish the ordinance.

This study aims to develop the education for college students who should perform the social role of the fut ure by conducting trekking activities including the characteristics, history, and culture of Cheonan area and then investigating the sociality and history of 36 college students. Taejosan, Seonggeosan, and Heukseongsan, which are part of the independent ring of Cheonan city, were selected as courses. The training was conducted by six instructors majoring in humanities, history, physical education and medicine. Teachers of humanities and history majors conducted theoretical lectures to raise the historical awareness of Cheonan area related to trekking course. In trekking practice, instructors of physical education and medicine majored in trekking safety education and course progress. Among the social development factors, responsibility, autonomy, and sociality were high. After the education, students recognized that the interest and necessity of history were high in order to understand the present society, thought that they made a lot of development compared to the previous one, and answered that the main development factors of history were the people and that there was a change in perception through this education. This study was composed of the survey after the education, so the psychological characteristics of the individual were not reflected, and it is difficult to generalize it because the number of subjects is small.

It is necessary for developing specific application protocol for mobile sensor end nodes and data collection devices that have constrained resources and computing powers. Because of these needs, IETF WG developed CoAP protocol and Internet draft was released, and processing to international standardization of this protocol. Because sensor nodes and information collection devices have restricted resources and computing powers, there are some limitations for applying to this proposed protocol directly. Thus in this paper we shows the implementation of full CoAP protocol for server, works on Linux and CoAP-Lite over telos which works on TinyOS for information collection devices. In this implementation we verified the main activities of CoAP protocol over USN by modifying some hardware with dependent algorithm.

The purposes of this study were to investigate the realities of community participation of young farmers and to suggest measures to activate community participation. The data were collected from 234 young farmers from rural Korea. With SPSS 13.0 program for Windows, Frequency, t-test, ANOVA, LSD for post-hoc interpretation and Factor Analysis were employed to analyze the data with statistical significance level of .05. The main results of the study and suggestions were as follows: 1) Young farmers were more likely to participate in watching television on community, discussion with others and internet search for community, while, rural youths were less likely to participate in contacting government and parliament. 2) Difficulties of community participations of young farmers were lack of time and insufficient information about participatory activities. The study suggested that young farmers should get more opportunities to participate in diverse types of active opportunities and practical information.

New media is an emerging industry sector. It sits at the nexus of what has become a main vehicle of the Knowledge Based Economy. the crossroads where the use of interactive multimedia technology meets the traditional uses of media. The current Education information Act provided school with PC, multimedia labs and connection to internet. Having such a facility in schools encourage teachers and students to use computers more often. Teachers demand for more educational multimedia contents than they can find in the market. Although there are many good contents, teachers find them unfit or inflexible for their curriculum. The purpose of this study is to identify the elements of standard multimedia studio facilities to develop multimedia contents in primary and secondary schools. The result of this study will provide guidelines for schools to facilitate their multimedia studio for teaching and learning activities, and developing contents for effective use of their facilities.

This study conducted an internet survey to explore consumers' behaviors for reducing food wastes and to examine factors affecting their actions. Consumer survey demonstrates that food preparers at home purchase foods two or three times a week on average and most of food wastes are generated in the process of cooking preparation. Results show that consumers who purchase foods at supermarket reduce food wastes by frequently buying a small amount of foods and checking the expiration date. Consumers with higher income diminish food wastes by purchasing appropriate amount of foods. Interestingly, if husband and wife work together for a living, they are more active for decreasing food wastes compared to a single worker.

$\ulcorner$Ministry Of Maritime Affairs And Fisheries$\lrcorner$was established on 8 August 1996 by emerging ex-$\ulcorner$Maritime and Port Administration$\lrcorner$, $\ulcorner$Fisheries Administration$\lrcorner$and some other marine-related organs such as $\ulcorner$Maritime Police Agency$\lrcorner$, $\ulcorner$Marine Accident Inquiry Agency$\lrcorner$, etc., for the purpose of enhancing development of national marine polices in various aspect and promoting marine safety and environmental protection activities. Therefore, the unification of marine casualty statistics is required for the need of appreciating present condition and problem. This paper shows the Client/Server computing system which could replace the existing Main Frame system set up by Maritime and Port Administration and Marine Accident Inquiry Agency. It also gives the way to connect every casualty related organ for data exchange of casualty information and INTERNET for opening casualty information to the public.

With the development of information and communication technology, information literacy and utilization are emerging as basic skills necessary for modern people. Accordingly, information education is becoming a basic literacy education for a nation. Unplugged computing is in the spotlight as a major educational method of information education. The main advantage of unplugged computing is that it is easy to convey basic theories or principles of computer science to students through play activities without the help of special information devices such as computers and tablet PCs. However, studies on student evaluation on unplugged computing have been very insufficient. In this study, students' evaluation standards are developed to maximize the educational effect of unplugged computing. The evaluation standards consist of four areas: participation, interest, satisfaction, and understanding of concepts. The results of this study can be used as a basic study for student evaluation of unplugged computing in the future.
