The environmental education is more and more important according to increasing environmental problems, but university students don't receive it actively. Actually, environmental education in university is conducted and focused on environmental engineering. In order to have an effect on environmental education for all engineering college students, the course of environmental education consists of various fields of engineering study including environmental engineering. The environmental education categories for engineering college students are determined by using an AHP technique in this study. After educating engineering college students with the developed environmental education course, we evaluated the environmental education performance using the survey on perception level and purchasing data of environmentally consciously products by statistical and RFM analysis.

In this study, we analyze the phenomena of professional development under the four categories: motivation toward entering college of education, pedagogical content knowledge, study of subject matter and future vision. We conducted a survey method for almost 60 computer education majors at S university ranging from freshman up to junior levels and interviewed 5 selected participants. According to SPSS analysis, there was no significant level difference in any category while male students responded more positively than female students in all the categories. To explore the survey results deeply, we selected 3 students from sophomore and junior levels and 2 extra senior students to conduct interviews. The interpretation of the data indicated how their academic problems revealed due to heavy curricular loads seeking second major and difficulties of pursuing pedagogical contents knowledge.

Nowadays, many people have much interest in health and quality of life. They can get information on foods known to have remedial value for certain illness from many healthcare experts on TV health related shows. Moreover, a lot of studies on these foods and their remedial value are consistently published. Thus, this study, on the ground that if we know prognosis of a certain disease in advance we can lead a better life without suffering from diseases, statistically analyzes specific students' responses to sub-health questionnaire. The analysis reveals that results of testing the equality of gender and 10 diagnosis indexes shows significant difference within 5% of significance level in 9 diagnosis indexes except for respiratory system. And the result of testing the equality of age and 10 diagnosis indexes indicates that there is no significant difference within 5% of significance level. In the study, students are divided into two age category. However, the age of 20s could be regarded as one category, which could be the reason why there is no significant difference.

The purpose of this study was to investigate preservice elementary school teachers' views on the relationship between science/technology and society. Freshmen (n=93) and seniors (n=82) at three universities of education were asked to express their views with 8 items in the Views On Science-Technology-Society, which consisted of two subcategories; 'influence of science/technology on society' (4 items) and 'influence of society on science/technology' (4 items). Mann-Whitney U test revealed that the scores of the freshmen were higher than those of the seniors. This trend was notable particularly in the item concerning 'influence of corporations on science/technology' and 'influence of interest groups on science/technology'. In comparing the scores by gender, a significant difference was found in the item concerning 'influence of policy on science/technology' for the freshmen.

Cyber forensics is used the process and technology of digital forensics as a criminal investigation in cyber space. Cyber crime is classified into cyber terror and general cyber crime, and those two classes are connected with each other. The investigation of cyber terror requires high technology, system environment and experts, and general cyber crime is connected with general crime by evidence from digital data in cyber space. Accordingly, it is difficult to determine relational crime types, collect evidence and the legal admissibility of evidence. Therefore, we considered the classifications of cyber crime, the collection of evidence in cyber space and the application of laws to cyber crime. In order to efficiently investigate cyber crime, it is necessary to integrate those concepts for each cyber crime-case. In this paper, we constructed a cyber forensics domain ontology for cyber criminal investigation using the concepts, relations and properties, according to categories of cyber crime, laws, evidence, and information of criminals and crime-cases. This ontology can be used in the process of investigating of cyber crime-cases, and for data mining of cyber crime; classification, clustering, association and detection of crime types, crime cases, evidences and criminals.

This study examined the nurse images perceived by nursing students. The study was specifically meant to determine what images grade 2 and 3 nursing students had about nurses before and after their clinical practice to define the nurse's image. The selected nursing students were interviewed to obtain their opinions on the definition and necessity of a nurse and what a great nurse should be like as well as their prejudice about nurses, and content analysis was carried out to categorize their statements. As a result, 48 significant statements and 14 categories were selected. The findings of the study might not be generalizable because the subjects in this study were selected by convenience sampling from two different nursing departments located in Gangwon Province and Gyeonggi Province. More concrete and reliable results are expected if more students from more geographic regions are investigated.

This article studies the understanding of acid and base concepts of the 3rd-grade students in middle school. An effective teaching strategy for improving their acid and base concepts was designed by considering students' prior knowledge using Lawson's learning cycle method. The control group was adapted by the traditional teaching strategy which isn't considering students' prior knowledge. After the class, understanding of acid and base concepts of treatment group was significantly higher than that of control group. But the level of students' understanding of strong acid, weak acid strong base and the strength of acid in aqueous solution was low even after the class of two groups. This indicates indirectly that the microscopic views of acid and base concepts in aqueous solution are not easy to learn for these students. For the four categories of acid and base concepts, students' responses were reviewed carefully and classified into scientific conceptions and misconceptions. These results will be useful for developing an effective teaching strategy of acid and base concepts.

In this study, the effects of a four-stage problem-solving strategy emphasizing planning and checking stages were investigated. Two high school classes (N=55) were randomly assigned to either treatment or control group, and taught about two topics, 'gas' and 'solution' for 8 class hours. Teacher used the four-stage problem-solving strategy emphasizing planning and checking stages in the treatment group, and used traditional lecture in the control group. Two-way ANCOVA results revealed that the test scores of the treatment group were significantly higher than those of the control group in the problem-solving ability, especially in the subcategories of 'conceptual knowledge' and 'mathematical execution'. There was significant interaction between the instruction and the level of prior achievement in the 'satisfaction' of the learning motivation. The lower level students in the control group were more satisfied with chemistry class than those in the treatment group. There was no significant difference between the two groups in the scores of the awareness of metacognition. Educational implications are discussed.
