WBI as new instructional method is known to be superior to the traditional face-to-face education method with regard to cost, time and effectiveness of learning. However, WBI lacks the humanity education that teaches human nature such as cooperative spirit or morality, since WBI delivers the knowledge in a mechanical way. The objective of this study is to design and implement Web-based humanity education system that supplements WBI. The system is designed to promote the intimate relation, reliability, and openness between teacher and student. Also, this system encourages the students to experience an affirmative human relation through group activities. In additions, this system promotes parents to join together for improving their understanding of children's learning process.

HIU(Hong-Ik University) has inculcated students with values necessary to serve society as independent, creative, and cooperative professionals. In HIU, students are encouraged to foster independent thinking, free from the influence of others, but are forged to cultivate their creativity in harmony with the knowledge and experience of others. In the department of MSDE(Mechanical and System Design Engineering), students are educated via three major courses for targeting engineering design, Creative Engineering Design (freshman), Design Process (Senior), and Creative Product Development (Junior). All these courses are based on personal tool exercises for design software and hardware and team-project group activities of the students with other team members. This paper will briefly discuss the main focuses of these courses and case studies of the teaching results.

Purpose: The purpose of this study was to examine the applicability of a flipped learning course in Women's Health Nursing for nursing students. Methods: A total of 200 senior nursing students participated in flipped learning class of pregnancy, delivery and postpartum area, which included team-based learning and self-reflection for 8 weeks. One group pre-post test design was adopted and the changes in learning motivation and satisfaction were examined. In addition, reflective journals of the students were analyzed by making a qualitative content analysis. Results: Students showed a significant increase in score of learning motivation in the posttest (t=-4.47, p<.001). They had a mean of 3.90 in learning satisfaction out of possible five points. As a result of content analysis, three themes were selected: 'Improved attitude toward active learning', 'Burden caused by excessive workload', and 'Valuing to the team-based activity' To be specific, six sub-themes were selected, with three positive and three negative categories: 'improved class attention and understanding', 'positive class participation by preparing lessons in advance', 'peer interactions through discussion', 'A lot of time and effort consuming', 'stress caused by the burden of preparing lessons', and 'difficulties in cooperative activities'. Conclusion: This study supports and confirms that the flipped learning can be a creative instructional model of positive teaching-learning strategy in clinical nursing courses to enhance students' learning motivation.

Korea, China and Japan show distinct features in their school environmental education, which are derived from their own spreading processes. Japanese school environmental education has developed as a result of assimilating of anti-pollution education and nature education, and has a feature that makes much of nature experiences. The introduction of 'Period for Integrated Study' in 2002 seems to begin activating Japanese school environmental education. Chinese school environmental education started in higher education institutions around the middle of 1970's, and has a feature that makes a point of scientific approach, even in primary education schools. The two government ordinances,'National Action Program for Environmental General Knowledge ($1996{\sim}2010$)' and 'Educational Scheme of Environmental Theme Study for Elementary and Secondary School Students' issued in 2003, gradually promote school environmental education in China. It is remarkable that Science and Technology Centers for Youth and also increasing environmental NPOs often support environmental activities in elementary or secondary schools. The most notable feature of Korean school environmental education is that 'Environment' has already offered as a regular elective subject in junior high school, and official 'Environment' textbook has published since early 1990's. Though, the adoption rate of 'Environment' is not yet so high. Each country's peculiar issues are as follows. Japan: (1) Students often lack basic knowledge about environmental important problems. (2) 'Period for Integrated Study' is now threatened with cutting hours by the idea of increasing periods for basic subjects to keep high achievement. China: (1) There are large regional differences and school distinctions in operation of environmental education. (2) Adult environmental education needs to be expanded, because the most part of Chinese have no experience of school environmental education. Korea: (1) The relationship between the administrative division which plans school environmental education and teachers group is not quite well. The adoption rate of 'Environment' in junior high school needs to be improved. The training of many teachers for environmental education instructors may be the most important and effective cooperative action among Korea, China and Japan, and for that purpose we ought to work on making a better handbook for instructors, at first.

The purpose of this study is to analyze students' recognition of the free inquiry activity and to investigate what effect the free inquiry activity of the 2007 Revised Educational curriculum revision has on the science inquiry ability of middle school students. To conduct the research we worked with 262 female students, 8 classes of first graders in a middle school. Among them, 4 classes were taught in free inquiry activity and the remaining 4 classes were taught in the traditional way. The results of Likert-questionnaire indicate that students were learning about cooperative spirit through group investigation activities and discussions and did not take the free inquiry activity as a hard activity. Also they showed positive reaction agreeing that this activity is both a helpful method in learning science and interesting. However, it seemed that the investigation tends to flow between the leading 1~2 members of the group and showed difficulty in carrying out the investigation as a group after school hours. It showed there are few problems and obstacles in operating the free inquiry activity. The free inquiry activity did not give any meaningful influence on the improvement of science inquiry ability of students. Integrative inquiry process skills did not give a relevant influence, however, it showed a meaningful influence on the improvement of basic inquiry process skills. Especially, among the low-ranking element of basic inquiry process skills, it enhanced the capacity for prediction.

Beta glucan was purified from Phellinus baumii and tested for its effect on the group performance of ants, a principal model of eusociality and of superorganisms. Japanese carpenter ants (Camponotus japonicus) were reared on diets containing beta glucans to characterize their effects on eusociality. Culturing structures for ants were assembled by implanting autoclaved soil into polyethylene terephthalate bottles. Three different eusocial strength indices were used to study the effect of beta glucan extract (BGE) on eusocial activities - the number of residence chambers, cooperative defense index (CDI), and group size and composition. Control, low- BGE, and high-BGE diets were prepared with the following three levels of BGE supplements in sucrose powder: 0, 20, and 50% (g/g). More residence chambers were observed in the BGE-fed groups than in the control. The CDI against a foreign queen ant was calculated according to the time taken to subdue the foreign queen. The high-BGE group took less time to complete their defense formation than the other groups. Differences were evident between control and BGE-fed groups in the total numbers of ants and eggs. The BGE-fed groups showed a significant increase in both the number of workers and the number of eggs. When fed with BGE, ants responded positively for all three eusocial strength indices. These results show that BGE exerts beneficial effects on the eusociality of ants as a superorganism.

This study investigates how elementary students used cognitive-emotional rebuttals in the context of modeling activities, especially on how their emotional and cognitive processes lead them to use rebuttals in terms of epistemic affect. Twenty-five fifth grade elementary students participated in the study as part of their science class. During the course of their sixth periods, students constructed a human respiratory system model through continuous discussion. The research results showed that elementary students used an elaboration-oriented rebuttal, a defence-oriented rebuttal, and a blame-oriented rebuttal in their modeling activity. The elaboration-oriented rebuttal interspersed with negative epistemic affect was used to elaborate on a student's explanation, and a negative epistemic affect was elicited from their cognitive discrepancy. On the other hand, defence-oriented rebuttal and blame-oriented rebuttal entangled with negative epistemic affect were used to defeat the students rather than help rigor evaluation of students' explanation, and the negative epistemic affect was elicited from the other students' undesirable behavior. These results suggest that students' rebuttals can be elicited by epistemic dynamics related to the epistemic affect. The study shows that if negative epistemic affect were elicited from the other students' naive or false explanations, such an emotion is natural in terms of model construction, and the model can be further developed through the acceptance of the elaboration-oriented rebuttals by students' emotion regulation. In addition, we suggest that negative emotions aroused from the worsening of relationships during small group modeling activities are difficult to regulate and can have negative effects on students' cooperative model construction.

Purpose - The Export Infrastructure Strengthening Program(EISP) is a project to expand exports of agri-food products through providing customized export information to food distribution companies and supporting overseas information activities. A total of 39.6 billion won was provided by 2016. So, the purpose of this study is to analyze whether EISP is effective for expanding exports of agri-food products. Research design, data, and methodology - A simple average difference between the export performance of the policy beneficiaries and the non-policy beneficiaries can be biased if the export capacity or inherent characteristics of the enterprise are not taken into consideration. In order to solve the problem of such a bias, the propensity score matching(PSM) method has been employed in this study. PSM is a method of converting the characteristics of an export company into an index through logit analysis and then reducing the matching to one dimension to improve the accuracy of the performance measurement. Results - The balancing test was conducted to determine how the characteristics of the policy beneficiary group and the matched policy non-beneficiary group corresponded to each other. As a result of the test, we could not reject the null hypothesis that there was no difference between the two groups, so that after the matching, the two groups were similar and the explanatory variables were well controlled. Using the nearest neighbor matching with propensity score estimating through logit analysis, we estimated average treatment effect on the treated(ATT). The food companies participating the EISP had the effect of increasing the exports of $ 5.88 million. As a result, the number of export contracts increased by 11.77, the number of exporting countries by 7.52, the number of export items by 47.51, and the number of buyers' consultation by 3.50. And overseas marketing expenses increased by 35.92 million won. Except for the number of export contracts, other export performance results showed statistically significant results. Conclusions - As the EISP has a positive effect on the expansion of agro-food exports, efforts should be made to find out the limitations or problems of the policy in the future and to make a greater contribution to the increase of exports.
