The followings are criteria of the proper textbook in the age of cyber-education. First, all the contents teachers want to teach must be found in the course of doing the computer and be used through the downloading. Second, all the contents students want to learn must be found in the course of doing the computer and help students` learning. There are seven or eight Chinese Letters textbooks for the middle school students in the sixth Education Curriculum and each textbook has different contents. But it is difficult for students to study different contents of these textbooks together. So the Chinese Letters textbook for the middle school students in the age of cyber-education must be made to solve this difficulty. Also the textbook can be best if all the contents are found and used in the course of using the Internet at any time. To make the proper Chinese Letters textbook for the middle school students in the age of cyber-education, we need many other teachers` help. We hope teachers to hold their good teaching materials in common through the Internet.

This study is first performed by researching the present conditions of Chinese characters to search for orientation of contents of Chinese characters. As a result, when Chinese characters in a broad sense are divided into Chinese character, words written in Chinese character, and Chinese writing contents of Chinese character and Chinese writing are being supplied through various methods. But there are relatively few contents that improve word power and make an active communication possible through words written in Chinese character. Although evaluation methods which are invented in game and multiple-choice questions applied to, there are lacks of contents that make immediate learning of self-evaluation possible using characteristics in learning on cyber. The learning through NIE and a few programs are therefore represented in this study to advance word power with a word written in Chinese character and evaluation methods on cyber. Especially, to perform immediate learning on-line Chinese characters can be grafted onto widely known programs. In the center of the learning through NIE on cyber among them this study shows a homepage that is developed personally. These Programs will make learning according to level of learners possible and make visitors react immediately because there are Chinese characters mode and Korean mode respectively.

수출용 토마토 하계육묘시 육묘 용기 와 육묘 일수를 달리 함으로써 나타나는 묘소질의 차이를 구명하고, 묘소질이 다른 묘를 정식하여 재배할 경우 생육과 수량에 미치는 영향을 구명코자 하였다. 육묘시의 묘 생육은 폿트 묘가 플러그 묘보다 좋았으며, 폿트 묘는 육묘 일수가 길수록 좋았으나 플러그 묘는 육묘 일수에 따른 차이가 없었다. 정식 60일 후의 생육도 정식 직전과 같은 경향이었다. 1화방 수확 개시기는 폿트 묘가 플러그 묘보다 빨랐으며, 육묘 일수가 길수록 빨랐다. 4개월간 수량은 폿트 묘가 플러그 묘 보다 유의하게 많았는데 수확 2개월까지 초기수량이 현저히 많았다. 폿트 묘는 수확 2개월까지는 45일 묘와 35일 묘는 큰 차이가 없었고 25일 묘가 가장 적었으나 수확 3개월째부터는 육묘일수에 따른 차이가 없었다. 플러그 묘에서는 수확 3개월가지는 35일 묘가 가장 많았고 25일 묘, 45일 묘 순이었으나 수확 4개월째에는 육묘 일수에 따른 차이가 없었다. 따라서 수출용 모모타로 요쿠 재배시, 수출시기와 수출기간에 따라 육묘 용기 용량 및 육묘 일수를 결정하는 것이 좋을 것으로 생각되었다.

In this paper, Korean's dining-out behaviors were compared and investigated according to gender and age. The change and the problem of dietary pattern in Korea were understood and we intend to provide the basic information for guidelines of Korean's dietary habits. The subjects are composed of 46.5% male and 53.5% female. According to age, groups aged 10~19 are 26.3%, 20's are 24.6%, 30's are 16.8%, 40's are 18.7%, and 50 and over age group is 13.6%. All of the age groups ate out for celebration of a special day or for social purposes. When dining-out, the most important criteria for selecting a restaurant was the taste of food. All age groups liked Korean-style restaurants the most. All age group eat a house meal at breakfast. At lunch, age groups 40 and below go to a restaurant in school or company and 50 and over age group eats house meal. In general, all age groups ate a house meal at dinner. At breakfast, all the age groups do not eat out. For lunch, they eat out four or five times a week. For dinner, the most of age groups except the 20's eat out two or three times a month and for the 20's age group, two or three times a week. The reason for selecting a Korean-style restaurant is that the food is 'well matched with one's appetite'. According to the above results, the dietary habits of 30 and over age groups are relatively good. On the other hand, in 10's and 20's age groups, they have an irregular meal and the ratio of skipping a meal is high. And they frequently use fast-food restaurants. In the future, the unbalance of nutrition in these age groups is expected. Therefore, the correct nutritional facts should be educated so that these age groups have a healthy dietary habit.

The recent development of information technology is transforming and redirecting our life into a new one radically different from the past, and such transition in the history of human civilization puts a new meaning on today`s mission of Chinese literacy program in Korea. Now the Chinese literacy education should set up a new set of goals and attempt to improve the methods of teaching and learning in addressing those essential problems including the restoring of the lost ethnicity, the healing of the inveterate social illnesses, and the creative development of the national spirit. Once we are in the age of simultaneous use of Chinese characters in Korea, the teachers of Chinese characters and Literature in highschool should bear in mind the following objectives: First, we should teach the students so that they may help our nation become a strong economy. Second, we should teach the students so that they may have the two Koreas reunified. Third, we should teach the students so that they may better served the tourists from abroad. Fourth, we should teach the students so that they may make our country a local center for knowledge and information. Finally, we should teach the students so that they may help make our spiritual and cultural potential better known to the world. In order to implement the goals in the specific situations, this paper made a survey on the personal opinions of both the teachers and the students and on the possible measures for improvement toward the problems of Chinese literacy education in highschool, and proposed a step-by-step method of teaching Chinese characters and literature for an effective implementation in highschool. As an introductory step dealing with the basic principles, the first step covers the teaching and learning of radicals, of penmanship, of and of reading. As a step for understanding and activating, the second step deals with resources teaching and learning, coinage teaching and learning, mind-map teaching and (earning, NIE(Newspaper in Education) teaching and learning, etc. As a unified level, the third step includes exploration teaching and learning, creative teaching and learning, cooperative teaching and learning, team-teaching methodology, and cyber teaching and learning. Thus the curriculum in highschool will be able to double its educational effect not only on the personal development of the students but also on the national benefits. In the age of simultaneous use of Chinese characters, the teaching of Chinese characters and literature in highschool should search for varied methods and approaches so that we may write a new chapter in which we are able to develop the benefits of our geographical location in the center of the Chinese-character culture zone and to contribute to the prosperity of our nation, the peaceful co-existence of the Far-eastern countries, and the enhanced level of spiritual and cultural awareness of the Globe. For this common purpose all levels of formal education from elementary school to college as well as research institutes should participate in this literacy program with a shared spirit.
