This study analyzed the effects of consumer knowledge and attitudes toward spending on environment-friendly agricultural products. Using data collected from 486 Ulsan housewives, results showed each score of consumer knowledge on and attitude to environment-friendly agricultural products was the middle level, and that mean monthly expenditure on environment-friendly agricultural products was 91,193 won. A multiple regression analysis was computed and indicated that higher spending on environmentally friendly agricultural products was related to high levels of consumer knowledge, positive attitudes to environment-friendly agricultural products, higher levels of household income, being a housewife in terms of occupation position, and post-graduate education levels. Furthermore, results also implied that consumer knowledge and attitudes to environment-friendly agricultural products were of greater influences than the demographic variables in their influence over spending on environment-friendly agricultural products.

The international environmental activity and environmental education began in 1970's. Environmental education in Korea was emphasized since the Forth National Curriculum. The Environmental Curriculum was regarded as one of the most important part in the Sixth National Curriculum in Korea. Environment-related reference texts of Elementary school were already developed. Soon, 'Environment' of middle school and 'Environmental Science' of high school will be developed. The purpose of this study were to analyse environment-related texts in the Fifth National Curriculum and to measure how much environmental education has achieved. As a environmental text for regular class, selected the environmental part in 'Science Part 1' and as environment-related reference text, 'Survival and Environment'. The environmental part of 'Science Part 1' was unit [Life and Environment]. According to the analysis of objectives, most of unit objectives were not stated in a detailed and precise manner. When the goals of environmental education were divided into four fields as follows, knowledge and information, skill, thinking and attitude, behavior and participation, unit objectives were mostly emphasized on knowledge and information of environment, exactly 44.5% of unit objectives and 89.6% of subunit objectives. The degree of relationship between unit objectives and contents was low. All the Check up-problems were about knowledge and information of environment. Environment-related reference text, 'Survival and Environment' was the only reference text for high school students in Korea and was organized in the form of the regular curriculum text. It was developed in Korean Education Development, Center with support of Korean Environmental Ministry in 1990. According to the analysis of 'Survival and Environment', the objectives of units and subunits were less stressed on knowledge and information than those of unit [Life and Environment] in the environmental part of 'Science Part 1' On the other hand, they were a little more stressed on skill, thinking and attitude, behavior and participation. And fifteen of all the seventy subunit objectives were not related with contents. In organization, this text included Thinking problems, Experiments and Inquiries, Reading, Developed studies and Check up-problem etc. It was remarkable that Inquiries leaded to individual activities and Developed studies to group discussions or individual inquiries. And as Check-up problems were presented as a form of activities, students could achieve many various objectives at the same time by solving one problem. To measure the achievement of environmental education by questionnaire, 497 high school students in total were selected from five different schools. Scores in subtest 'behavior and participation' and subtest 'thinking and attitudes' were 13.19 and 18.18, respectively. Actually, most students had a positive thinkings and attitudes in their hearts about environmental problems, but many of them actually did not take actions to solve environmental problems and to protect environment. Scores in subtest 'knowledge and information' and subtest 'skill' were 10.76 and 10.81, respectively. The higher the score students got in 'knowledge and information', the higher the score in 'skill'. It implies that learning of skills is based on learning of knowledges and informations about environment has not always ensured positive thinkings and attitudes or active behaviors and participations to solve environmental problem.

This study was conducted to investigate the differences in households, parental perception, and dietary behaviors of preschool children from kindergartens with environment-friendly food service (environment-friendly food service group; EFG) versus children from kindergartens with general food service (general food service group; GFG). We sought this basic information to examine the impact of environment-friendly agricultural products in preschool food services. Age, education level, and monthly family income of the EFG were significantly higher than the GFG. The frequency of purchasing environment-friendly agricultural products was significantly higher in the EFG than the GFG, with the most frequently purchased items in both groups being vegetables. The GFG had a significantly higher perception than the EFG in the superior quality of environment-friendly agricultural products; however, a greater proportion of the GFG than the EFG thought environment-friendly products were too expensive. The most frequent reason for purchasing environment-friendly agricultural products in both groups was safety. When purchasing environment-friendly agricultural products, the most important selection factor for the majority of both groups was the label certifying quality assurance. Both groups also considered price reduction as essential for promoting environment-friendly agricultural products. In regard to parental perceptions on food service in kindergarten, the EFG had a significantly higher satisfaction with the nutritional adequacy of the menu compared to the GFG. Both groups considered food safety and health as primary reasons for using environment-friendly foods in the preschool food service, with a greater proportion of the EFG than the GFG responding this way. There were significant differences between the EFG and GFG, as the main satisfaction from using environment-friendly foods in the EFG was safety, freshness, and good hygiene, whereas the main satisfaction in the GFG was a good food service menu, freshness and good hygiene. Dietary behaviors of preschool children in the EFG were also significantly superior to the GFG. Thus, environment-friendly agricultural products have positive effects on the dietary behaviors of preschool children and should be increased in the preschool food service. Lowering prices and a strict supervision of quality assurance is also necessary to promote consumption of environment-friendly food materials.

Education environment of modern society is rapidly changing along the usage of various device and development of contents. Learners of diverse age groups and genders are exposed in smart education environment. Thus in order to investigate effective smart education contents production, this study classified interactive types that affect learning satisfaction into CAI (Computer Assisted Instruction) based , NCS (Network Communication System) based , and NTS (New Technology System) based . Then we investigated how each interactive types affect immersion, utility, self-efficacy, practicality, and stimulation. The effects were measured according to the learner's gender and age. As the result, interactive types do affect smart education, where male had higher learning satisfaction for CAI based, game type, and wiki type while female had higher satisfaction for relationship establishment type and experience type. Also, for age group, the 10s preferred NTS based, 20~30s NCS based, and 40s and over CAI based interactive type. Thus, if satisfaction levels according to gender and age are considered when producing smart education contents, it may be possible to create educative contents that meet the dispositions of the learners.

This research was conducted to assess the effects of an engineering education accreditation program devised by the University of Seoul on higher education outcomes by comparing and analyzing the evaluation results of engineering accredited students (31) and those who are not accredited (47) with the OECD AHELO (Assessment of Higher Education Learning Outcomes) in 2013. The AHELO assessment tool consisted of 25 multiple-choice questions which evaluated generic skill-learning outcomes, also using contextual surveys to establish the students' backgrounds. The results were evaluated statistically. In the results from the multiple-choice exam for generic skill learning outcomes, accredited students scored 1.35 points higher than non-accredited students. Secondly, according to the contextual survey related to students' university education experience, such as lectures, seminars, group projects, and online tutoring, it was found that accredited students were provided more activities in seminars and group projects. Moreover, for class activities, more of these were provided to accredited students, especially in the areas of assortment-structuralization and teamwork-based activities. Thirdly, according to the contextual survey results related to participation in class, specifically regarding asking questions and participating in discussions, interacting with the professor, and opportunities for study time, there were no recognizable differences between accredited and non-accredited students, However, while accredited students at least had opportunities to gain experience in most areas, there were some areas for which education resources were not provided to non-accredited students. Therefore, for the University of Seoul, our results imply that accredited students may show better performance in the areas of academic accomplishment and in their educational environment as compared to non-accredited students. These results demonstrate that the engineering education accreditation program positively contributes to employment competitiveness while also improving the necessary global standards of higher education outcomes.

It is crucial to understand the characteristics of learner questioning due to the effects it has on learning. This study focuses on the effects of middle school students questioning on their academic achievement in an online inquiry learning environment. A survey of 827 middle school students was conducted; the students took part in an online math and science program offered by a center for the gifted. Throughout the survey, learner questioning was analyzed, and its correlation with academic achievement was investigated. An analysis was based on questioning categories of a low- and high-level questions from previous studies. Through the survey, it was found that the number of learner questions asked in the online environment was small, but the number of low- and high-level questions were almost equal. Secondly, the higher the academic achievement level of the student, the higher the possibility they would ask either low- or high-level questions. Lastly the group of students in both low- and high-levels of questioning earned the highest average scores on formative evaluations and inquiry tasks. This indicates that regardless of the level of questions, the act of questioning itself is highly related to the academic achievement. However, in the case of advanced learning projects, the quality of questioning and high-level questioning affected the academic achievement of students. Based on these results, implications for the encouragement of learner questioning and support for asking high-level question are suggested.

Very long life fatigue tests were carried out on 16Mn steel base metal and its welded joint by using the ultrasonic fatigue testing technique. Specimen shapes (round and plate) were considered for both the base metal and welded joint. The results show that the specimens present different S-N curve characteristics in the region of $10^5-10^9$ cycles. The round specimens showed continuously decreasing tendency while plate specimens showed a steep decreasing step and an asymptotic horizontal one. The fatigue strength of round specimen was found higher than plate specimen. The fatigue strength of as-welded joint was 45.0% of the base material for butt joint and 40% for cruciform as-welded joint. It was found that fracture can still occur in butt joint beyond $5{\times}10^6$ cycles. The cruciform joint has a fatigue limit in the very long life fatigue regime ($10^7-10^9$ cycles). Fatigue strength of butt as-welded joint was much higher as compared to cruciform as-welded joint. Improvement in fatigue strength of welded joint was found due to UPT. The observation of fracture surface showed crack mainly initiated from welded toe at fusion areas or geometric discontinuity sites at the surface in butt joint and from welded toe in cruciform joint.
