This research explores how different corporate cultures can influence the post-M&A performance of the airlines undergoing strategic M&A in Korea. The sample size of this research is 214 respondents that is strictly limited to the employees of airlines under M&A process, and CFA and SEM were employed for the statistical analysis. This research investigated that corporate cultures including group-oriented, development-oriented, and rationale-oriented will positively influence the post M&A performance of both efficiency and effectiveness through a mediation of collaboration during M&A process. In contrast, relations between grouporiented culture and interaction, interaction and effectiveness were not revealed positive influences. The findings of this research will provide valuable insights into the potential risks that can impede successful M&A within the M&A process, specially focusing on the conflicts between organizations stemming from different organizational cultures, which can have an adverse impact on M&A performance.

The purpose of this research paper is to re-valuate the factors that affected the Royal Navy's rearmament and preparation for war by conducting analysis on the discussion held in the Britain on the strategic priorities and Navy's coping measures adopted during the interwar period. After the end of the WWI, each of the military arms of the Britain faced significant difficulty in securing budget and increasing their military power all throughout the interwar period, and the Navy was not an exception. The WWII that got started on September 1939 was the turning point in which this difficulty led to full-fledged crisis. Immensely many criticisms followed after the war and problems were identified when it comes to the Royal Navy's performance during the war. This type of effort to identify problem led to the attempt to analyze whether Royal Navy's preparation for war and rearmament policy during interwar period were adequate, and to identify the root causes of failure. Existing studies sought to find the root cause of failed rearmament from external factors such as the deterioration of the Britain itself or pressure from the Treasury Department to cut the budget for national defense, or sought to detect problems from the development of wrong strategies by the Navy. However, Royal Navy's failed preparation for the war during interwar period is not the result of one or two separate factors. Instead, it resulted due to the diverse factors and situations that the Britain was facing at the time, and due to intricate and complex interaction of these factors. Meanwhile, this research paper focused on the context characterized by 'strategic selection and setting up of priorities' among the various factors to conduct analysis on the Navy's rearmament by linking it with the discussion held at the time on setting up strategic priorities, and sought to demonstrate that the Navy Department's inadequate counter-measures developed during this process waned Royal Navy's position. After the end of WWI, each of the military arms continued to compete for the limited resources and budget all throughout the interwar period, and this type of competition amidst the situation in which the economic situation of Britain was still unstable, made prioritization when it comes to the allocation of resources and setting up of the priorities when it comes to the military power build-up, inevitable. Amidst this situation, the RAF was able to secure resources first and foremost, encouraged by the conviction of some politicians who were affected by the 'theory of aerial threat' and who believed that curtailing potential attack with the Air Force would be means to secure national security at comparatively lower cost. In response, Navy successfully defended the need for the existence of Navy despite the advancement of the aerial power, by emphasizing that the Britain's livelihood depends on trade and on the maintenance of maritime traffic. Despite this counter-measuring logic, however, Navy's role was still limited to the defense of overseas territory and to the fleet run-off instead of sea traffic route production when it comes to the specific power build-up plan, and did not understand the situation in which financial and economic factors gained greater importance when it comes to the setting up of strategic priorities. As a result, Navy's plan to build its powers was met with continual resistance of the Treasury Department, and lost the opportunity to re-gain the status of 'senior service' that it had enjoyed in the past during the competition for strategic prioritization. Given that the strategic and economic situation that Korea faces today is not very different from that of the Britain during the interwar period, our Navy too should leverage the lessons learned from the Royal Navy to make the effort to secure viable position when it comes to the setting of priorities in case of national defense strategy by presenting the basis on why maritime coping should be prioritized among the numerous other threats, and by developing the measures for securing the powers needed effectively amidst the limited resources.

The aim of this study is to see school science education from the perspective of CoP (Community of Practice) and to explore the possibility of strategic CoP in Korean school settings. To do this, we conducted a survey using SCaCoP instrument with more than 1600 students from 14 science core schools (SCSs), which were selected across the country, and analyzed their school curriculum, which can be summarized as follows: First, compared to other tracks in SCSs, like the Nature and the Humanity Classes, students of the Science Core Class (SCC) showed significantly higher scores of CoP features for all five factors of SCaCoP (i.e. responsibility of learning, common interest, mutual relationship, open participation, and practice). Second, students of SCC considered activities that require interaction and collaboration among community members (like experiments, hands-on activities, club activities, project works, R&E) to be very positive. Third, SCC students thought that the educational activities of SCSs were not only effective to CoP aims (i.e. self-driven learning, sharing learning outcomes, peer collaboration) but also positive to general aims of science education (i.e. acquiring knowledge, understanding scientific concepts, science-related attitudes). In other words, it appears that educational activities that were effective in vitalizing the CoP have positive effects on ordinary science education, too. These features of SCSs illustrate its possibility of forming strategic COPs in the context of often government-driven Korean education and of bringing in the innovations of school science education.

Recently, interest in energy tranisition is rising. Energy transition requires active participation and cooperation of diverse stakeholders, including users / citizens, in that it requires not only changes in technological factors but also changes and coordination of various social factors. Living labs are attracting attention as one of the ways to do this. This article is a detailed analysis of the activities of the mini-PV living lab in the urban area from 2016 to 2017 at the Seoul, Sung Dae Goal. Through the Living Lab, mini PV DIY products, backup centers, local financial services, and the development of a variety of education and training strategies have been achieved. These activities and achievements were analyzed through questions raised on strategic, tactical, and operational levels, as well as through multi-level perspective and interaction between initiative, regime, and niche. In conclusion, this living lab activity confirmed the possibility of a 'transition lap' to solve social problems such as sustainability of energy production and utilization. In particular, it gained remarkable results in terms of the operational leves of transition management governance, that is, transition experiment, and it was also remarkable in that it was the initiative of citizens. However, it did not proceed without difficulty. In particular, structural problems such as the conflict between the flexibility inherent in living lab and the bureaucratic rigidity of the financial support organization have appeared. There was also a limitation that there was no 'transition field' on the strategic level necessary to replicate and expand strategic niches while spreading the knowledge gained from the transition experiment, forming the vision of transition.

This study was conducted with the aim of presenting a strategic implication for effective political campaign in the election situation which is held almost every year including the early presidential election. For this purpose, the $2{\times}2{\times}2$ triad experiment design of framing, involvement, political efficacy. The result shows that the main effect of framing and political efficacy was found, but the main effect of involvement was not shown. And also a result of two-way ANOVA, the interaction between framing and involvement was significant, but the interaction effect between framing and political efficacy was not significant. In addition, the three-way interaction effects of framing, involvement, and political efficacy were also significant. This study suggests that prospect theory is not often used to test the effects of political campaign messages and suggests new perspectives on political campaign strategies by introducing the prospect theory into election campaign message research.

The purpose of the present research was to study the self-regulation of the child during mother child interaction. That is. this study focused on how mothers regulated children's problem solving efforts before children began to function as independent agents capable of self-regulation. The emphasis was on the "regulation-by-others" that preceded "self-regulation". The subjects of this study were 30 mother-child dyads. The dyads were divided into 3 groups of 10 dyads each on the basis of the child's age (2, 3, and 4 years of age). The instrument used for this study was the "truck puzzle" devised by Wertsch, McNamee, Mclane and Budwig (1980). The problem solving task in this study required the dyad to make a puzzle in accordance with the model puzzle. The interaction of 30 mother-child dyads was observed and analyzed flH verbal and non-verbal behavior used by the mother to regulate the child's behavior. One-way ANOVA, Scheffe post hoc comparision and Spearman's rank-difference correlation were used for the statistical analysis of the data. The results revealed that there were significant age trends in regulation-by-others and self regulation in joint cognitive activity; that is, there were developmental transitions from regulation by-others to self-regulation in connection with crucial strategic behavior (looking at the model). Significant differences were found in mothers' interventions after children's gaze at the model in joint cognitive activity; that is, the mean proportion of mothers' intervention for the 2-year-old group was the highest and that of the 4-year-old group was the lowest. There were no significant age-related differences in mothers' use of referential perspectives in joint cognitive activity. Children's regulation- by-others increased and children's self-regulation decreased in proportion to mothers' use of referential perspectives.

Usability heuristics("heuristics") are general principles for usability evaluation during user interface design. This method is commonly used by Human Computer Interaction(HCI) professionals; however, the most widely used set of heuristics which were originally created by Nielsen has not yet been found practical in the current state of Korean technologies. In our prior research, we found that some of Nielsen's heuristics are difficult for some evaluators to understand and insufficient to fully evaluate Korean applications, due to the broad-applicability of these heuristics and differences in cultural context. Therefore, in this study, professionals in computer science and related fields evaluated Nielsen's ten usability heuristics in order to gather logical bases for finding areas for improvement. The results of this study will help creating a new set of heuristics that will better valuate more recently developed applications.
