The purpose of this study was to find the effect of molecular movement model based instruction on high school students' conceptions of diffusion and osmosis. The study was composed of two groups, the traditional instruction group in which the so-called traditional instruction was performed, and the other group in which interventions by researchers were made. The subjects of the traditional instruction group consisted of a total of 242 high school students from Seoul, Gwangju and Mokpo. The subjects of the model based instruction group consisted of 177 first-year high school students in Mokpo. The study was focused on the use of the term of 'molecular movement' in their explanation of diffusion and osmosis in the correct contexts. In general, students who got the molecular movement model based instruction showed more frequent use of the terms of 'molecular movement' in the correct contexts than the control group students did. It was found that misconceptions including teleological explanations changed into scientific explanations by the intervention. It seemed that the molecular movement model led students to make scientific explanations on natural phenomena. A further research is recommended to assess the improvement of teleological explanation and scientific attitude by the molecular movement model.

This study was performed to investigate the consumption and the preference of chungkukjang products among the middle school students. The subject were 538 middle school students(male 283, female 255) in $3^{th}$ grade, and were asked to fill out the questionnaire. The collected data were analyzed by SAS package. The result showed that most students knew about traditional chungkukjang(88.5%) and chungkukjang powder(68.2%), but only 43.5% and 29.4% of the respondents knew about raw chungkukjang and chungkukjang pill, respectively. When asked how often they eat chungkukjang products, traditional chungkukjang were taken often, but chungkukjang powder, raw chungkukjang and chungkukjang pill were shown to be taken relatively less. Over 60% of the students responded that they liked chungkukjang products, because of 'encourage by parents' and 'good for health', but there was no statistical difference by gender. When asked about the reasons for the dislike of the chungkukjang products, male students responded 'bad smell'of traditional chungkukjang, while female students 'eplied' not eating at home'. The students disliked the chungkukjang powder, chungkukjang pill and raw chungkukjang because of 'not knowing it.' These results showed that the social interest and support for the chungkukjang products were necessary and there was a need to advertise the chungkukjang products.

The purpose of this study was to identify the effect of mind map activity on scientific attitude and science achievement in elementary school science. The subjects of this study were fifth-grade students selected from two classes in elementary school located in Seoul. The subjects were classified into two groups: One group is composed of thirty-eight students(experimental group) who were participated in mind map activity, and the other is composed of thirty-five students(control group) who were participated in traditional teaching situation. Pretest showed that there were no significant differences between experimental and control group in scientific attitude and science achievement. The results were as follows: First, the experimental group showed a significant improvement in the post-test science achievement compared to the control group. Second, the experimental group showed insignificant improvement in the post-test scientific attitude compared to the control group. Third, female students and mid-ranking group showed a significant improvement in the post-test science achievement. Fourth, in sex and academic ranking, experimental group did not show significant difference in the post-test scientific attitude. In conclusion, mind map activity was more effective than traditional teaching situation on science achievement. But mind map activity was less uneffective than traditional teaching situation on scientific attitude.

Objective: This study was performed to compare knowledge of and expectations for traditional medicine between Korean, Chinese and Taiwanese, to figure out whether these factors influence the intention to use traditional medical treatment in the future. Methods: One-hundred ninety-nine Korean, eighty-five Chinese, and one-hundred seventy-four Taiwanese subjects responded to the survey. A one-way ANOVA was performed to compare experiences of traditional medical treatment, knowledge of both traditional medicine and western medicine, expectations for traditional medicine, and future intention to use traditional medical treatment. Multiple regression analyses were also performed to evaluate a possible correlation between the other factors and the intention to use traditional medical treatment in the future. Results: The experiences of traditional medical treatment were in the order of Taiwanese, Korean, and Chinese, from more frequent to less frequent. Chinese had more knowledge of traditional medicine compared to Taiwanese and Koreans, and the expectations for traditional medicine were in the order of Chinese, Korean and Taiwanese, from higher to lower. The intentions to use traditional medical treatment in the future were in the order of Korean, Chinese and Taiwanese, from more to less. Multiple regression analyses showed that experiences of traditional medical treatment, knowledge of traditional medicine, and expectations for traditional medicine were associated with the intention to use traditional medicine in the future in Korean and Taiwanese, but not in Chinese. Only the expectations for traditional medicine were associated with the future intentions to use traditional medical treatment in Chinese. Conclusions: These findings suggest that Korean and Taiwanese may need to improve their knowledge of traditional medicine whereas Chinese need to link their knowledge of traditional medicine with the intention to use it in the future. Understanding the characteristics of traditional medicine would probably contribute to enhancing the intentions to use it more.

According to the World Health Organization (WHO), 1.37 million people died of lung cancer all around the world in 2008, occupying the first place in all cancer-related deaths. However, this number might be decreased if patients were detected earlier and treated appropriately. Unfortunately, traditional imaging techniques are not sufficiently satisfactory for early detection of lung cancer because of limitations. As one alternative, breath volatile organic compounds (VOCs) may reflect the biochemical status of the body and provide clues to some diseases including lung cancer at early stage. Early detection of lung cancer based on breath analysis is becoming more and more valued because it is non-invasive, sensitive, inexpensive and simple. In this review article, we analyze the limitations of traditional imaging techniques in the early detection of lung cancer, illustrate possible mechanisms of the production of VOCs in cancerous cells, present evidence that supports the detection of such disease using breath analysis, and summarize the advances in the study of E-noses based on gas sensitive sensors. In conclusion, the analysis of breath VOCs is a better choice for the early detection of lung cancer compared to imaging techniques. We recommend a more comprehensive technique that integrates the analysis of VOCs and non-VOCs in breath. In addition, VOCs in urine may also be a trend in research on the early detection of lung cancer.

Recently, the rabid development of information technology has brought enormous changes in education. Consolidation of communications and multimedia technologies are enabling the new educational paradigm such as distance learning and virtual education. Furthermore, many studies in the education engineering field report that teaching using multimedia technologies more enhances students' performance than the traditional instructor-teaching method. However, little research regarding the education using multimedia has been done in the MIS filed. None of multimedia-related studies could be found in the top-ranked MIS journals published in Korea for the last five years, and only a few studies were found even worldwide. In this regard, the purpose of this study is to investigate which features of multimedia software are most important to enhance the teaching results of students. From the previous research, we found out the specific features of the educational multimedia software which are considered to affect the students'performance, and defined the research variables related to those educational software features. And, based on the constructivism and motivation theory of the education engineering field a theoretical research model and research hypotheses were developed. Perceived usefulness of the class and a student's perceived interests in the class were used as surrogate variables to measure teaching performance. Total 277 students participated separately in one of the two multimedia classes which have continued for three weeks. One was C programming language class and the other was multimedia CD-title development class. Each student listened for the multimedia session of the class using multimedia software and, at the end of the multimedia session, answered the survey questionnaire. The results of the study show that motivation to the class and the contents of education were statistically significant to the students'performance in the class. That implies, not only in the traditional instructor-teaching method but also in the multimedia class, that the contents of education itself and student's motivation to the class are most important to raise instructional results.
