As the global business environment is rapidly changing due to the 4th industrial revolution, new jobs that did not exist before are emerging. Among them, the job that companies are most interested in is 'Data Scientist'. As information and communication technologies take up most of our lives, data on not only online activities but also offline activities are stored in computers every hour to generate big data. Companies put a lot of effort into discovering new opportunities from such big data. The new job that emerged along with the efforts of these companies is data scientist. The demand for data scientist, a promising job that leads the big data era, is constantly increasing, but its supply is not still enough. Although data analysis technologies and tools that anyone can easily use are introduced, companies still have great difficulty in finding proper experts. One of the main reasons that makes the data scientist's shortage problem serious is the lack of understanding of the data scientist's job. Therefore, in this study, we explore the job competencies of a data scientist by qualitatively analyzing the actual job posting information of the company. This study finds that data scientists need not only the technical and system skills required of software engineers and system analysts in the past, but also business-related and interpersonal skills required of business consultants and project managers. The results of this study are expected to provide basic guidelines to people who are interested in the data scientist profession and to companies that want to hire data scientists.

This study conducted an empirical analysis of the factors affecting the job commitment of employees within a financial sales organization, focusing particularly on agile leadership and organizational justice. Agile leadership was subdivided into four components: adaptability, collaboration promotion, proficiency, and an agile approach, whereas organizational justice was broken down into distributive justice, procedural justice, and interactional justice. Data were gathered through an online survey, and 245 valid responses were subjected to hierarchical regression analysis. The results revealed a significant positive effect of distributive justice, interactional justice, adaptability, promotion of collaboration, and an agile approach on job commitment among the employees of the financial sales organization. However, the influence of proficiency, a component of agile leadership, and procedural justice, a dimension of organizational justice, did not prove to be statistically significant. The order of influence among the significant variables was found to be: adaptability, interactional justice, promotion of collaboration, distributive justice, and an agile approach. These findings confirmed the impact of agile leadership in financial sales organizations, traditionally viewed as conservative, and suggested practical implications for the financial sector to adapt in anticipation of the Fourth Industrial Revolution.

As the Fourth Industrial Revolution progresses, the importance of startups is becoming more prominent. Additionally, the role of accelerators in ensuring the sustainability of startups is also being emphasized. Therefore, in this study, among the services provided by accelerators to startups, the mentoring service, education service, funding service, and networking service tried to empirically analyze the structural relationship that affects startup performance through the dynamic capabilities of start-ups. To achieve this, we conducted a survey in February 2023 targeting startup CEOs and executives who had experience with accelerator program services. A total of 238 valid responses were analyzed using structural equation modeling with Amos 24. The results of the empirical analysis were as follows. The accelerator program services, including mentoring, education, funding, and networking services, had a significant positive effect on startup dynamic capabilities. Among the accelerator program sub-factors, networking services had the highest impact on startup dynamic capabilities, followed by mentoring, funding, and education services. Furthermore, startup dynamic capabilities were found to have a significant positive effect on startup performance. On the other hand, startup dynamic capabilities were found to mediate the relationship between mentoring, education, funding, networking services, and startup performance. Dynamic capabilities are a critical factor for startups, and the finding that accelerator programs can have a significant impact on startup performance by mediating these dynamic capabilities is significant both academically and practically.
