The purpose of this article is to re-interpretate 'Post Catch-up Studies' on the Korean innovation system with the framework of 'Transition Studies'. The viewpoints of the vision, research area and system innovation process of Post Catch-up studies are reviewed and reconfigurated. The Transition Studies concepts of Sustainability, Coevolution of industry and society, and transition management are introduced into the Post-catch up Studies and discussed. It is suggested that Post catch-up studies should support sustainability system transition and make use of transition management tools for the sustainable post catch-up innovation and policy.

For continuous and successful innovation, changes in innovation system are required and have been magnified as a new controversy. With high public interest in changes of innovation system, Transition theory and policy in Netherlands are now attracting attentions of many researchers and policymakers. Transition policy in Netherlands is distinguished from existing policies for fundamental system change in that take remarkably different views and methods. Typical examples of transition in Netherlands are such as sustainable energy transition, biodiversity and natural resource transition, sustainable agriculture transition, and sustainable transportation. Transitions in Netherlands are still in the early stage of it but several positive effects are witnessing. However some problems - linking theory and practice, ambiguity of transition concept, linking long-term vision and short-term, resistance of existing regime, implementation problem, diffusion of support, etc.- to be tackled are still remaining. In spite of those problems, many lessons can be drawn from them. To guide structural changes in innovation system into the right path and cope with lock-in problem by existing system and regime, we need to learn from Transition theory and policy in Netherlands.

This study examined whether sequential transition patterns of social play differed by children's social competence. The social competence of sixty 5-year-old children was rated by their teachers using the Social Competence Scale(NICHD Early Child Research Network, 1996). Children's social play was observed during free play and coded by criteria developed by Robinson et al(2003). Results showed differences in children's social play behaviors by social competence and differences in the transition patterns of children's social play level by social competence. Children with higher social competence showed a transition pattern moving toward cooperative-social interaction, whereas children with lower social competence showed a transition pattern moving backward to solitary or onlooker behavior.

Using qualitative methods of interviewing, documentation, and participant observation, this study explored kindergarten children's understanding on their transition into elementary school. Phenomenologically, results showed that children understood that the transition into elementary school means thrownness (Geworfenheit) and projection (Entwurf). When children answered the question about why they want to go to elementary school, their responses demonstrated an understanding of the inevitability (thrownness) of transition. That is, they understood that entering elementary school was an unavoidable step for growing up. They expected(projected) that they would enjoy new activities and opportunities in elementary school. While they felt anxious about stem teachers and difficult studies, they looked forward to intellectual development, various indoor activities, outdoor exercises, and multi-layered encounters.

The IT outsourcing industry has been widespread for decades since the growth of the system integration industry stagnates and companies need to curtail expenses and improve the quality of IT services. According to previous studies on the success factors of the IT outsourcing, its transition phase is significant because of continuity of business and the handover of knowledge. Since a transition phase consists of several projects, but its goal is different from general projects, it needs special and professional management. Therefore, recent IT outsourcing business starts to introduce PMO (project management offices), of which success strongly depends on the competencies of the PMO. However, there are only few studies on which competencies of the PMO are important. In this paper, we suggest an evaluation model of transition PMO competencies derived using the repertory grid technique and the analytic hierarchy process. Additionally, we compare the differences between the views of several stakeholders on the importance of the competencies.

Using a person-centered approach, the current study investigated latent profiles for the emotional and behavioral problems of students in sixth-grade in elementary school and second grade of middle school. The aim was to explore latent transition patterns and verify the factors affecting the transitions. The participants were 1,937 adolescents who responded to the 3^rd year (6^th grade of elementary school; Time 1), 4^th year (1^st grade of middle school), and 5^th year (2^nd grade of middle school; Time 2) of the Korean Children Youth Panel Study. Latent profile and latent transition analyses were performed. The results were as follows: first, the latent profile of emotional and behavioral problems changed from Time 1 to Time 2. The latent groups at Time 1 were classified into low, moderate, high, and externalizing-dominant, whereas at Time 2, five groups were identified: low, moderate, high, externalizing-dominant, and withdrawal-dominant. Second, transition analyses revealed that although 22.3-57.0% of latent groups remained unchanged, there were significant changes over time between groups, as a new group ('withdrawal-dominant') emerged in Time 2. Third, different factors influenced the latent profile transition of emotional and behavioral problems depending on the transition pattern. Higher levels of self-esteem, better relationships with peers and teachers, and lower levels of parental inconsistency meant emotional and behavioral problems had not worsened at Time 2. The results suggest that early interventions are needed during the transition from childhood to early adolescence.

This paper reviews the studies on the pressure drop and the heat transfer in microchannels. Although a lot of studies about the single-phase flow have been done until now, conflicting results are occasionally reported about flow transition from laminar flow to turbulent flow, friction factor, and Nusselt number. Some studies reported the early flow transition due to relatively greater wall effect like surface roughness, but the other studies showed that the flow transition occurred at the Reynolds number of about 2300 and the early flow transition might be due to less accurate measurement of the channel geometry. Also, there have been arguments whether the conventional relation based upon continuum theory can be applied to the fluid flow and the heat transfer in microchannels without modification or not. The studies about the two-phase flow in microchannels have been mostly about investigating the flow pattern and the pressure drop in rectangular channels using two-component, two-phase flow like air/water mixture. Some studies proposed correlations to predict two-phase flow pressure drop in microchannels. They were mostly based on Lockhart-Martinelli model with modification on C-coefficient, which was dependent on channel geometry, Reynolds number, surface tension, and so on. Others investigated the characteristics of flow boiling heat transfer in microchannels with respect to test parameters such as mass flux, heat flux, system pressure, and so on. The existing studies have not been fully satisfactory in providing consistent results about the pressure drop and the heat transfer in microchannels. Therefore, more in-depth studies should be done for understanding the fundamentals of the transport phenomena in the microchannels and giving the basic guidelines to design the micro devices.

Socio-technical systems are receiving growing attention as a core concept in the process of searching for proper solutions to sustainable growth. In this paper, we review the way for governing socio-technical transitions from a governmental perspective. Based upon the governance studies and transition research, we set social coordination and locus of transition pressures as transition contexts to differentiate transition policy governance. We propose four types of policy governance for sustainable socio-technical transitions: leading, facilitative, coordinative and persuasive. Analysis on four case based upon this typology shows different transition polices of each transition pathway in analytical aspect. It provides basic criteria for policy makers to design effective transition policies in normative aspect. Also, this paper can contribute to closing the gap between transition research and governance studies.
