The study applied chemistry classes based on Collaborative Problem-Solving for Competency(CoProC) Instruction Model to 86 high school seniors and recognized the resulting changes in Character Competence through character competence test, analysis of argumentation, and analysis of reflective writing. In addition, the analysis of the correlation between the assessment results showed what each evaluation method meant to assess Character Competence. The study found that the average score of Character Competence rose in all three assessments, but differences were found in the detailed factors. Character competency test is meaningful in helping students participate with a sense of mastery of learning as a self-evaluation, and the analysis of the argumentation process seems to be an appropriate evaluation method to evaluate the Character Competence shown by students' words and actions through course evaluations. An analysis of reflective writing showed the advantage of being able to analyze Character competencies that are difficult to show in action by looking back on the entire course of learning. In addition, given that the correlation between the three assessment results is very low, it is expected that the three Character competency assessment methods will be conducted together to obtain detailed and comprehensive information on students' character competencies.

This study was intended to investigate predictability among variables having an effect on problem solving skill and achievement in collaborative learning by utilizing SNS at university. To this end, 61 first-year students majoring in early childhood education at I community university in the national capital region were surveyed. And on the basis of the collected data, a multiple regression analysis was carried out. The results of carrying out the analysis are as follows. First, it was shown that self-efficacy, peer learning and help seeking had a significant effect on problem solving skill, and explained 70 of variability in problem solving skill. Second, it was shown that peek learning, help seeking and problem solving skill significantly predicted achievement, and explained 72% of the variability in achievement. Third, problem solving skill partially mediated the relationship between self-efficacy and achievement. The above-mentioned results imply that learning motivation should be increased so that learners have self-efficacy in order to improve college students' academic achievement in collaborative learning by utilizing SNS at university, and a class environment making it possible to actively provide peer learning and help seeking should be designed and a specific scheme enabling the enhancement of the problem solving skill should be considered.

Due to the recent worldwide economic downturn, companies are required to put more effort into their innovation and quality improvement. In particular, business relationship is increasingly emphasized to be changed from a vertical relationship to a more horizontal relationship, such as collaborative partnership based on trust. In the logistics industry, through the collaboration, consignors can gain competitive advantages by focusing on their core capabilities, and freight forwarders also take advantages of securing stable cargoes and specialist expertise in distribution. Therefore, this study aims to identify key factors for developing a collaborative partnership between freight forwarders and consignors, and further examine the differences between the two groups empirically by using questionnaire survey. Based on the results, the main factors were found as follows: 1) Trust Building, 2) Competence Improvement, 3) Business Ecosystem and 4) Government Assistance. According to the analysis on sub-factors, first, among the four main factors, it turned out that trust is the most important variable. Specifically, the sub-factor of providing regular and stable service was revealed to be most critical. Second, it was found that forwarders need to improve services on 'Information Exchange System' and 'Electronic Data Interchange'. Finally, it is necessary for both consignors and forwarders to have better understanding of partnership. Key implications for both groups are highlighted based on the results.

Current global construction market has grown at a dramatic expansion rate every year in connection with more market accessibility by foreign contractors. The market openness is largely due to globalization of world construction markets, rapid development of world-wide telecommunication technologies, the formation of collaborative acquisitions and joint ventures among contractors, development of regional Free Trade Blocks, and just name a few. This paper focuses on the formation of collaborative networks when expanding into new foreign markets. The social network analysis (SNA) is introduced to investigate a variety of the collaboration patterns and also their impacts on the performance. To this end, the collaboration cases of 600 international construction projects performed by Korean contractors since 1990 were collected and classified into firm's size, project types, collaboration modes, and performance levels using social network analysis. The results showed a direction in establishing business strategy associated with experienced or inexperienced contractors in international construction projects.

This study examined the factors that influence creative performance in corporate collaboration projects. Specifically to facilitate team collaboration, we identified that scaffolding, which is one of the important factors in organizational learning communication, and the Boundary Objects, which are collaboration tools & vehicle, influence performance. The survey was collected for 203 employees who experienced collaborative projects, and three-step mediated regression analysis was conducted after conducting exploratory factor analysis. In other words, we examined the median effect of boundary objects on the impact of scaffolding on creative collaborative performance. Analysis showed that while the effects of the boundary objects in relation to the impact of cognitive scaffolding on creative performance were not significant, emotional scaffolding had a full-scale effect on the creative performance and also had a full-scale effect on the efficacy performance. Given these results, it is necessary to share a vision and form personal relationships among team members in order to activate them, since scaffolding is useful in organizational learning and boundary objects also have some effect as a medium for promoting collaboration in projects.
