The importance of organizational learning is increasing. Drawing on regulatory focus theory and upper echelon theory, this study aims to identify the relationship of the regulatory focus of managers and three aspects of organizational learning, namely breadth, depth, and speed of organizational learning. While identifying the significant influence of promotion focus on the three aspects of organizational learning, we found that the influence of promotion focus of breadth of organizational learning is statistically stronger than that of prevention focus.

The purpose of this study was to verify the effectiveness of the employee metacognition and it's positive effect on employee agility. Also it aims to investigate the mechanism through the cascading multi-mediating effect through the role breadth self-efficacy and learning agility in such a relationship. In order to solve the common-method bias, independent and dependent variables were measured with time lag, and the relationship between variables was clearly verified by applying the position and the length of time worked with the supervisor as control variables. In testing the hypothesis, 478 questionnaires collected from whom worked at the company has more than 300 office workers in various industries were analyzed. As the result, firstly metacognition had a significant positive(+) effect on employee agility. Second, role breadth self-efficacy was found to positively mediate the relationship between metacognition and employee agility. Third, learning agility was found to mediate metacognition and employee agility positively(+). Fourth, metacognition serially mediates role breadth self-efficacy and learning agility, and the positive(+) effect on employee agility was verified. In addition, metacognition had a greater effect on member agility when passing through role breadth self-efficacy and learning agility rather than the direct effect on employee agility.

This study aims to analyze which subsidiary configuration strategy is more effective under uncertainty especially technology base multinational corporations (henceforth MNCs). In previous studies real option theory scholars argue that high breadth subsidiary configuration is most effective strategy because that provides flexibility to MNCs global network. In this study I want unveil more various types of uncertainty such as technology and learning uncertainty which are more important for technology base firm and further more examine the effect of MNCs subsidiary configuration on firm R&D performance each uncertainty case. Empirical study is performed by negative binominal model based on Japanese 108 multinational corporations. The result shows that under technology uncertainty, high breadth subsidiary configuration is better for firm R&D performance but under learning uncertainty high depth subsidiary configuration is better. Thus, the effects of MNCs subsidiary configuration on firm value can differ by types of uncertainty.

Identifying ship types is an important process to prevent illegal activities on territorial waters and assess marine traffic of Vessel Traffic Services Officer (VTSO). However, the Terrestrial Automatic Identification System (T-AIS) collected at the ground station has over 50% of vessels that do not contain the ship type information. Therefore, this study proposes a method of identifying ship types through the Random Forest Classifier (RFC) from dynamic and static data of AIS and V-Pass for one year and the Ulsan waters. With the hypothesis that six features, the speed, course, length, breadth, time, and location, enable to estimate of the ship type, four classification models were generated depending on length or breadth information since 81.9% of ships fully contain the two information. The accuracy were average 96.4% and 77.4% in the presence and absence of size information. The result shows that the proposed method is adaptable to identifying ship types.

This paper is to examine new programme of study for geography by a revised geography(including historical, geographical and social understanding) National Curriculum in England. The new primary and secondary National Curriculum was respectively issued in 2007 for implementation from September 2008 and 2010 for implementation from September 2011. The revised National Curriculum was changed more than that of 1995 and 2000 in terms of its formation and content. Especially, Primary National Curriculum was rebuilded to the six areas of learning, in the end KS1-2 geography was integrated in 'historical, geographical and social understanding'. As a result of that, the subject named as geography only remains for KS3. Nevertheless, the new National Curriculum is consisted of programme of study(PoS) and attainment target(AT). But new programme of study was changed more than that of former curriculum in terms of its formation and content. Programme of study for primary school is organized with curriculum aims, the importance of areas of learning, essential knowledge, key skills, cross-curricular studies, breadth of learning and curriculum progression. On the other hand, that of geography for KS3 is organized with curriculum aims, the importance of geography, key concepts, key processes, range and content, curriculum opportunities. This paper examined on categorical features of new programme of study for KS3 geography and its implications for effective geography curriculum design and planning.

The Blended Learning of K-12 education can he complimented to exceed the limits of the traditional face-to-face instructional method and can help learners have experiences with both various interactions and different learning experiences. Specifically, in K-12 education blended learning has a strength in being able to integrate on-line instruction with off-line instruction and actively help learners emerge with a breadth of knowledge gained collaboratively.<중략>For the objective of the study, that is, an investigation by a literature review process, the mode) of the process of collaboratively emerging knowledge as well as the alternative model of the concept can be applied as a developmental research method, which can improve practical procedure, process, and prescription. For overcoming the model and the real situation, this study was applied with Checkland(1999)'s soft system methodology, using$\square$the comparison of the model and real situations$\square$part and$\square$defining the alternatives$\square$of Checkland(1999)'s methods. In conclusion, analyzing the conceptual model and real situation helps in the development of a model which can minimize the discrepancy between the conceptual model and the real situation within K-12 education.

With the growing number of web services, there arise issues of finding suitable services. But, the traditional keyword search method is insufficient for two reasons: (1) this does not capture the underlying semantics of web services. (2) this does not suffice for accurately specifying users' information needs. In order to overcome limitations of this keyword search method, we propose a novel syntactic analysis and ontology learning method. The syntactic analysis method gives us a breadth of coverage for common terms, while the ontology learning method gives a depth of coverage by providing relationships. By combining these two methods, we hope to improve both the recall and the precision. We describe an experimental study on a collection of 508 web services that shows the high recall and precision of our method.

The dynamic nature of the World Wide Web challenges Search engines to find relevant and recent pages. Obtaining important pages rapidly can be very useful when a crawler cannot visit the entire Web in a reasonable amount of time. In this paper we study way spiders that should visit the URLs in order to obtain more “important” pages first. We define and apply several metrics, ranking formula for improving crawling results. The comparison between our result and Breadth-first Search (BFS) method shows the efficiency of our experiment system.

This study tried to explore the ways to operate service learning more effectively by analyzing the educational effects of service learning and changes in learning sentiments that appeared in the service learning operation process established for the realization of the Christian educational philosophy at a small local Christian university. The analysis was conducted using NVivo11, focusing on the reflection journals of students who participated in service learning in the first semester of 2022 at J University. As a result of the study, through service learning, personal competence growth, self-reflection and will to change, self-esteem and self-efficacy, social and civic aspects, social responsibility enhancement, community (community) empathy and awareness of participation, and helping others There were educational effects such as an increase in the breadth of understanding. In addition, learning emotions that appeared in the service learning process included positive emotions such as gratitude, challenge recognition, pride, confidence, and responsibility, and negative emotions such as worry (difficulty), upset, regret, and awkwardness. It is a measure to increase the educational effect based on the learning emotion shown in the service learning process. When operating service learning, the service period at the visiting institution is increased to 6 weeks or more, and based on close interaction and detailed analysis of the educational environment in the planning stage, Suggest to develop and operate a plan. In addition, if you have the opportunity to receive feedback from your professors and colleagues through demonstrations and mock presentations in the classroom before visiting the institution, and finally have the opportunity to visit the institution again after the results of service learning are announced, more quality service learning education will be operated. Based on the results of this study, it is expected that more valuable and meaningful service learning education opportunities will be provided to learners by designing and operating a practical and sophisticated service learning curriculum.
