This letter presents a model for a dynamic collaboration (DC) platform among cloud providers (CPs) that prevents adverse business impacts, cloud vendor lock-in and violation of service level agreements with consumers, and also offers collaborative cloud services to consumers. We consider two major challenges. The first challenge is to find an appropriate market model in order to enable the DC platform. The second is to select suitable collaborative partners to provide services. We propose a novel combinatorial auction-based cloud market model that enables a DC platform among CPs. We also propose a new promising multi-objective optimization model to quantitatively evaluate the partners. Simulation experiments were conducted to verify both of the proposed models.

As migrants develop businesses abroad, entrepreneurship needs specific strategies due to some barriers when establishing and doing businesses. This paper examines the kinds of problems that have been faced in Indonesian migrant entrepreneurships in Taiwan and how the entrepreneurs cope with the difficulties. They use structural and cultural strategies for survival, seize the opportunities for self-development, and develop future careers. Research result shows that the limitations of Indonesian entrepreneurships in Taiwan are related to institutional issues, migrant status, business regulations, resource-providing institutions, language barriers, competition among migrants and locals, and capital. Hence, migrant entrepreneurs must conduct strategic actions to continue their businesses by developing innovations to grow and survive. Some measures include changing from offline to online marketing especially when the COVID-19 pandemic hit, product diversification using migrants and local people's assistance and networks, and setting competitive prices. This paper is based on qualitative research. The data were obtained through interviews in East Java-Indonesia and in Taiwan in 2022. The data were analysed using the descriptive analysis with sociological perspectives.

The study analyzed the topics and the types of the selected articles from the 20-year-old Journal of Educational Technology(JET), flagship journal of the Korean Society of Educational Technology. Further the results were compared with those of the Educational Technology Research & Development journal. Results indicate that the JET has grown in terms of quantity and quality since its birth 20 years ago. The JET seems to be independent as a young adult. Some issues and concerns were also identified: The articles of the JET are more inclined to Experimental design in terms of research type, and to Design in terms of research topic. Balance across Types and Topics needs be kept for long-term, healthier growth. The emergence of e-Learning and high technology of Korea offered opportunities to the field. However, the monopoly of e-Learning that consumes most of the limited space of the JET raises a red flag. More balanced and quality-oriented endeavors were suggested for another 20 years coming.

This paper examined opportunities and limitations of building an innovation cluster based on large scale research facilities (LSRF). For this purpose, success factors of innovation clusters were drawn from the literature, and categorized into knowledge & technology, transaction cost & agglomeration economies, hardware & software infrastructure, and government policy & strategy. Utilizing the categorization as an analytic framework, case studies of CERN and SPring-8 were performed. The results showed that there were various innovation processes for both cases, creating opportunities for developing innovation clusters in terms of knowledge and technology. On the other hand, in the case of SPring-8, there were disadvantages in the transaction cost and agglomeration economies, being located in a remote area due to the nature of the facility. Software & hardware infrastructure of SPring-8 limited its potential for innovation clusters. Regarding government policy and strategy, CERN, as a multinational institution, did not consider an innovation cluster in a specific region despite some advantages. An innovation cluster around SPring-8 was promoted by government policy despite some disadvantages. In other words, the advantages and disadvantages were enhanced or complemented by software & hardware infrastructure and government policy & strategy. Based on the results, this paper provides the implications for the Korean International Science-Business Belt.

The object of this study identifies the weights of SWOT factors in hidden champion. And the other purpose of the study is to test the differences of weight between Korea hidden champion group and Germany theirs group. The survey research is employed for the hidden champion CEOs of two countries. This research is employed the AHP(Analytic Hierarchy Process) for the weight of SWOT factors in hidden champion based on an empirical survey done to 61 firms which are to be fostered as Korean type hidden champion and 40 firms which are to be fostered as Germany type hidden champion. And then the t-test assesses whether the weight means of two groups are statistically different from each other. The weights of SWOT factors of hidden champion have been identified. There are the differences of weight between Korea group and Germany group. The order of Korea group's weight is following by the strength (0.3062), the opportunities (0.2344), the threat (0.1804), and the weakness (0.1157). The order of Germany group's weight is following by the strength (0.2603), the opportunities (0.2286), the threat (0.1604), and the weakness (0.1432). The technology capability of strength, the lack of knowledge on overseas market of weakness and the market uncertainty of thereat have statistically differences between two groups. However, the sub-factors of opportunities statistically have no differences.

This study analyzes China's technology billionaires. However, this study does not show the accumulating process of wealth in each of the Chinese billionaires, because there are many technology billionaires, but only deals with the macro analysis of the technology billionaire; the pattern of existence, comparison with other industries, the process of wealth creation reflecting China's particularity, and comparison with the world's technology billionaires. The findings of this study are as follows. First, more than 10 billion yuan of Chinese billionaires will emerge from 2004. Second, in the early days, illegal and corruption made rich, but the wealth of own efforts has gradually increased. Third, the real estate and manufacturing billionaires are still strong overall, but the growth of billionaires in technology, medicine and finance industry is remarkable. Fourth, in the case of the top 10 richest, four are from real estate, four from technology, and two from manufacturing and distribution. Most technology billionaires are in Guangdong, Zhejiang, Beijing and Shanghai. The determinants of the number of billionaires are GDP, exchange rate to US Dollar and Shenzen Stock Index, and those of technology billionaire are GDP and exchange rate. Given the relationship with existing theories, this study can be called the fifth type of billionaire research. Conceptually, the main reason for accumulating wealth is the search for policy opportunities, market opportunities and technology opportunities.

This research was conducted to assess the effects of an engineering education accreditation program devised by the University of Seoul on higher education outcomes by comparing and analyzing the evaluation results of engineering accredited students (31) and those who are not accredited (47) with the OECD AHELO (Assessment of Higher Education Learning Outcomes) in 2013. The AHELO assessment tool consisted of 25 multiple-choice questions which evaluated generic skill-learning outcomes, also using contextual surveys to establish the students' backgrounds. The results were evaluated statistically. In the results from the multiple-choice exam for generic skill learning outcomes, accredited students scored 1.35 points higher than non-accredited students. Secondly, according to the contextual survey related to students' university education experience, such as lectures, seminars, group projects, and online tutoring, it was found that accredited students were provided more activities in seminars and group projects. Moreover, for class activities, more of these were provided to accredited students, especially in the areas of assortment-structuralization and teamwork-based activities. Thirdly, according to the contextual survey results related to participation in class, specifically regarding asking questions and participating in discussions, interacting with the professor, and opportunities for study time, there were no recognizable differences between accredited and non-accredited students, However, while accredited students at least had opportunities to gain experience in most areas, there were some areas for which education resources were not provided to non-accredited students. Therefore, for the University of Seoul, our results imply that accredited students may show better performance in the areas of academic accomplishment and in their educational environment as compared to non-accredited students. These results demonstrate that the engineering education accreditation program positively contributes to employment competitiveness while also improving the necessary global standards of higher education outcomes.
