지식기반 경제에서 가치 생산의 중추는 지식과 정보이다. 이에 따라 국내에는 공적 지식정보 지원 정책이 잘 마련되어 있으나, 이에 대한 평가는 미흡하였다. 본 연구에서는 방송 영상 분야에 종사하는 현업인을 대상으로 지식정보 서비스 이용 및 만족도를 분석하고, 제도적 개선점을 모색해 보았다. 분석 결과, 현업인들의 공적 지식정보 지원 서비스의 이용은 높지 않았으며, 만족도 역시 낮은 것으로 나타났다. 정보 신뢰도는 높은 반면, 시의성이나 유용성에 대한 평가는 부정적이었다. 그러나 응답자들이 개별 노력을 통해 지식정보를 수집, 분석하고 있는 점에 근거할 때, 지식정보 수요는 높은 것으로 분석된다. 완성된 형태의 지식정보를 제공하기 보다는 이차적 가공이 가능한 원형의 지식정보 제공이나, 지식정보 획득 수단의 제공, 시장친화적 지식정보의 제공 등을 통해 공적 지식정보 지원 서비스의 효용을 높일 필요가 있을 것으로 보인다.

The purpose of this study was to analyze the differences in the understanding level of the Korean traditional seasonal customs during summer (i.e. Buddha's birthday, Dano festival, Yudu festival and Chilseok) before and after the execution of a educational program concerning seasonal customs and determine if elementary school teachers recognize a need for this kind of educational program. The subjects of this study were 168 students in the 4th grade at two elementary schools (84 students each for the experiment group and the control group) and 249 teachers at the elementary schools in Yangju city. The major results of this study are as follows : First, it was shown that there is no significant difference in the understanding level of seasonal customs between the experiment group and the control group in the pre-test, but after carrying out the educational program, it was indicated that there is a statistically significant difference between the experiment group and the control group in the post-test. Second, in addition to strongly pointing out the necessity of seasonal customs education, the teachers recognized that it is desirable to teach seasonal customs to students through the discretionary activity class corresponding to the seasonal divisions in the year and that it is especially important to perform the educational activity through traditional plays and to utilize audio-visual media. Also, teachers hoped that a seasonal customs program suitable for elementary school students would be required, along with the development of instructional materials, and finally that the schools need to further develop teacher training through field inspections and practice.

In mathematics education, teaching-learning activity can be divided largely into the understanding the mathematical concepts, derivation of principles and laws, acquirement of the mathematical abilities. We utilize various media, teaching tools, audio-visual materials, manufacturing materials for understanding mathematical concepts. But sometimes we cannot define or explain correctly the concepts as well as the derivation of principles and laws by these materials. In order to solve the problem we can use the computer. In this paper, character and movement state of various quadratic function graph types can be used. Using the computers is more visible than other educational instruments like blackboards, O.H.Ps., etc. Then, students understand the mathematical concepts and the correct quadratic function graph correctly. Consquently more effective teaching-learning activity can be done. Usage of computers is the best method for improving the mathematical abilities because computers have functions of the immediate reaction, operation, reference and deduction. One of the important characters of mathematics is accuracy, so we use computers for improving mathematical abilities. This paper is about the program focused on the part of "the quadratic function graph", which exists in mathematical curriculum the middle school. When this program is used for students, it is expected the following educational effect. 1, Students will have positive thought by arousing interests of learning because this program is composed of pictures, animations with effectiveness of sound. 2. This program will cause students to form the mathematical concepts correctly. 3. By visualizing the process of drawing the quadratic function graph, students understand the quadratic function graph structually. 4. Through the feedback, the recognition ability of the trigonometric function can be improved. 5. It is possible to change the teacher-centered instruction into the student-centered instruction. For the purpose of increasing the efficiencies and qualities of mathmatics education, we have to seek the various learning-teaching methods. But considering that no computer can replace the teacher′s role, tearchers have to use the CIA program carefully.

Purpose : Sexual abuse especially in younger group have been growing. This study was performed to propose the fundamental data for developing early education program to prevent damage from sexual harassment in elementary school students. Method : Questionnaire survey on cognitions and experiences about sexual harassment was done on 3125 elementary school students from seven elementary schools in Busan area from January to March, 2002. Data analysis was done with SPSS (ver 10.0). Results : Though 82% of the students have ever herd about sexual harassment previously, but self assessment of 'well-known' was only 5%. About 40% of them have ever experienced audio-visual sexual materials mainly through PC (18%), media (14%), etc. And, 60% of them have ever educated about sexual harassment. In cognitions, they agreed 'unwanted touch', 'intentional showing his (her) own body', 'send lewd mails and pictures', but disagreed 'ask massage from aged', 'gaudy joke' as one of sexual harassment. In attitudes, 'no response', 'defense with friends and family', 'express unpleasantness apparently' were desirable pattern, instead, 'his (her) own responsibility', 'problem only between person concerned', 'neglect is the best way' were undesirable. About 24% of them have ever experienced at least one of the fifteen types of sexual harassment with major types of lewd mails pictures (11%), hugging (5%), ask massage (4.7%) and unwanted touch (3.3%). The experience by gender was higher in girls (25.0%) than boys (22.4%) with no statistical significance. The mean level of cognition and attitude out of one hundred was $70.3{\pm}28.1$ and $73.5{\pm}15.9$, respectively. The mean frequency of experience was $0.4{\pm}1.1$ times. The level of cognition and attitude was higher in girls, 6th graders, and in ever educated group (p<0.001). Conclusions : The cognition level of elementary school students about sexual harassment assessed considerable. And, they also experienced several types of sexual harassment, though not too much. Therefore, compatible education program let them able to protect themselves from sexual harassment should be developed and applied even in early school age.

This study, with teachers form elementary schools in Chungju-si as its subjects, has investigated influence of school forest on satisfaction with school greenspace and environmental education. It has reached the following conclusions. As for recognition of and satisfaction of school greenspace there were meaningful differences between teachers form school forest model schools and ones from common schools, which was thought to be due to positive effects of school forest movement. It appeared that environmental education was carried out through audio-visual materials once a week in most schools. On the other hand, as for class places, 'classroom in parallel with outdoor class' and 'classroom education' appeared to be carried out most frequently in the case of school forest model schools, and 'classroom education' in the case of common schools. However, considering the fact that 'field learning' the most important element in environmental education, appeared to be carried out least frequently in both of the groups, which suggests that we should improve it for future through introduction of various field-experience learning programs. As a result of the survey of satisfaction with environmental education, some meaningful differences were recognized between school forest schools and common schools, and 'presence or absence of field learning spaces' was the most frequently answered reason for 'satisfied' and 'unsatisfied'. Thus, 'schools' and related institutions' enthusiastic efforts are needed for providing field-experience spaces where children can directly access to and explore into nature.

The study was performed to investigate the dietary behaviors and attitudes toward the lesson of Food and Nutrition in Home Economics course among middle school students in rural area. The participants of the study were 647 second-grade students in a middle school in Geumsan-gun, Chungcheongnam-do. The main nutrition problems of the students were found to be deviated food-intake habits and irregular meal time. Twenty six percent of female students and 14.8% of male students skipped breakfast. Seventy three percent of the total students have a tendency of food aversions. The food groups they dislike most were vegetables and pulses. They answered they got nutrition information mostly from the class at school. Their favorite topic in the lesson of Food and Nutrition was cooking. Some students did not like Food and Nutrition because it requires too much memorization. Teaching methods they liked were lecture, discussion, and audio-visual presentation. Although 81.7% of the students thought that the lesson of Food and Nutrition was useful, only 17.1% of the students practiced what they learned from the lesson. These results confirm that nutrition education in middle school is essential to the students in rural area and that it is needed to find an effective teaching method and materials for them to change positively their food behaviors at daily life.
