The purpose of this study was to perform oral health education using UCC media in consideration of middle school students' characteristics, and to investigate the intelligence area related to knowledge conveyance, affective area related to attitude change, and psychomotor area related to behavioral change. As a result, it tried to develop further the strengths of UCC media based oral health education and overcome its weaknesses in order to increase learners' interest and have any behavioral changes. By letting learners have the education at YouTube at any time, rather than use one-time educational medium material it is possible to keep educating learners. In the future, by applying the education to health education programs and health education, it will be possible to convey education contents to learners accurately, give motivation to learners, and thereby increase educational results.

The purpose of study is to develop the web-contents for web based instruction (WBI) with the Science Fiction Movie (SF) and investigate the effects of application to the science learning. The results are as follows. 1) Science fiction movies for the earth science classes of middle school were selected, that is the Armageddon, the Apollo13 and the Total Recall. They are related to the chapters, the Earth and the Stars in the 8th grade science textbook. 2) The developed WBI materials were applied to the science classes of the 2nd grade in middle school through the Internet Line. and then the changes of attitude on science and recognition on using the science fiction movies to the class were analyzed. The results show that the science fiction movies have so much related to the contents of science learning and the developed WBI materials are effective to the science classes(p<0.05), but no meaningful (p>0.05) to the attitude on the science excluding the students' interest to science learning.

The types of the accidents caused by intra-city buses and the changing tendencies of driving attitudes are analyzed before-and-after semi-public management system of intra-city bus system is implemented. On the basis of analysis, the measures on the decrease of traffic accidents are considered and the results are as follows. First, it showed that the traffic accidents decreased generally as a result of definition of the progresses of traffic accidents of intra-city buses before-and-after the system is implemented and with the passing of time after the system was operated. Second, the factors which influence the decrease of traffic offenses before-and-after semi-public management system of intra-city bus are the decease of violation, safe driving duty and the job security. Also the cause which mostly influence to the decrease of traffic accidents is defined. Finally, the measures of decrease of traffic accidents are arranged and proposed as a result of PROXSCAL method.

The purposes of this study are to look into the changing processes of mathematical beliefs and attitudes of the students and to propose the plans how to manage cooperative learning, what can contribute to cognitive affective domains of mathematics learning in applying STAD-based cooperative loaming to mathematics class. So we, the researchers performed cooperative learning in the fifth grade of elementary school and did the exams of mathematical beliefs and attitudes, interviews, supplementary Questions. And students showed meaningful changes in 'the need of cooperative learning', 'critical thinking', 'the acceptance of thoughts of others'. Meanwhile, there were possibilities what all the members of one group can't recognize their errors in STAD, so we proposed 'Tongsinsa'. And we presented concrete methods how to reconstruct groups and somethings to consider when students are not satisfied with the group activities.

참달팽이(Koreanohadra koreana)는 환경부에서 지정한 법정보호종(멸종위기 야생생물 II급)이며, 전라남도 신안군 홍도와 하태도에서만 서식하는 한국고유종이다. 반면, 그 동안 참달팽이 지방산에 대한 연구는 진행된 바 없다. 홍도와 하태도를 대상으로 계절, 미소서식처, 지역 차이에 따른 참달팽이의 지방산 구성 변화를 비교하기 위해 분석에 사용한 표본의 개수는 총 99개였다. 실험결과 총 16가지의 지방산이 검출되었으며, 주로 식물질 먹이에서 유래되는 다중불포화지방산(PUFAs)이 53.6%로 가장 높았다. 반면, 동물성 또는 미생물에서 유래하는 단일불포화지방산(MUFAs)은 31.4%, 포화지방산(SFAs)은 15.0%로 상대적으로 적게 검출되었다. 참달팽이의 총 지방산량 변화는 PUFAs의 변화와 가장 강한 상관관계(R²=0.88, p < 0.0001)를 보였다. 계절별로 PUFAs는 봄 (13.20 mg/g)과 여름 (13.08 mg/g)이 가을 (12.06 mg/g)과 겨울 (12.40 mg/g)에 비해 많은 양이 검출되었다. 미소서식처별 PUFAs는 초지대(12.80 mg/g)에서 석회질 지대(12.48 mg/g) 보다 다소 높게 나타났다. 반면, 지역별로 홍도(12.65 mg/g)와 하태도(12.64 mg/g)는 차이가 거의 없었다. PUFAs는 참달팽이의 먹이원을 기반으로 한 서식지의 질을 추적할 수 있는 하나의 지표로서 활용가치가 높을 것으로 기대된다.

In this study, the instructional influences of the conceptual change model based on the cognitive conflict and the conceptual change model emphasizing the social consensus were investigated. The subjects were 109 7th-graders in a boys' middle school in Seoul, and were taught about the changes of states, density, and dissolution for 8 class periods. The hypotheses provided in the instructions were constructed from the results of a pilot test. Prior to the instructions, three tests regarding the perceptions of discussion, the attitudes toward science instructions, and the perceptions of participation were administered. Two types of the conceptual change instructions and the traditional instruction were used in the treatment groups and the control group, respectively. After the instructions, the students' achievement, the conceptions, the perceptions of discussion, the attitudes toward science instructions, and the perceptions of participation were investigated. ANCOVA results revealed that the scores of the treatment groups were significantly higher than those of the control group in the achievement test. Although the score of the treatment group using the conceptual change model emphasizing social consensus were higher than those of other groups in the conceptions test, the differences were not statistically significant. The perceptions of discussion were significantly more positive in the treatment group using the conceptual change model emphasizing social consensus than in the control group. However, there were no significant differences in the scores of the attitudes toward science class and the perceptions of participation among the three groups. Educational implications are discussed.

The aim of this study is to analyze the effects of DVR(Driving Video Recorder) operation on decreasing the number of traffic accidents, the cost of traffic accident claim, and the behavioral change in drivers' driving. The data for this research are obtained from taxi drivers in Busan. For this, Structural Equation Model and two-way ANOVA are employed for empirical analysis. Overall results of this study show that the number of traffic accidents of 4 taxi corporations in Busan has decreased by average 32.7 percent after using DVRs. In addition, as to the cost of taxi accident claims, it is expected that the DVR operation has a considerable effect on economic benefits of taxi corporations. Moreover, this study could make clear the difference in behaviors between DVR users and non-users, and discriminate the positive and negative impacts of the DVR operation on the drivers' driving behavior. The study quantitatively examined the indirect impact of 'attitude', 'subject norm' and 'behavioral control' factors on planned 'behavior', and the direct impact of 'behavioral control' factor on the planned 'behavior'. This study suggests that they should add the video recoding function of DVRs when operation recorder(blackbox for the car) is obligatorily set up on cars for business by traffic security law.

The importance for local development, which residents' attitudes have reflected, is well known. Therefore, in order to formulate an approach for sustainable development, a study on sustainable waterfront development has become necessary. This study performed the first step analysis of Limits of Acceptable Change(LAC) System that considers the local residential attitude to make the analysis and standard for acceptable development type in the waterfront. This study used the characteristics of the residents, the social exchange theory, and the LAC System. This was done because it is useful to ensure that basic data can be used for the establishment of management objectives. Yeoju-Si was selected as the site for the investigation. A total of 240 surveys were obtained. Analyses were conducted to 1) determine the relationships between the residents' attitudes toward the waterfront development type and the acceptable development type and 2) to examine relationships between the residents' characteristics and the residents' attitudes toward the waterfront development. The results of this study are as follows: The development pertaining to the parameter 'nature education' arguably has the potential to generate substantial revenues for Yeoju-Si and could link the local development and conservation. This study concludes that the area of residence were closely correlated with the residents' attitudes.
