As the security threat and crime rate have been increased all over the globe, the video surveillance system using closed-circuit television (CCTV) has become an essential tool for many security-related applications and is widely used in many areas as a monitoring system. However, most of the data collected by the video surveillance system is used as evidence of objective data after crime and disaster have occurred. And, often time, video surveillance systems tend to be used in a passive manner due to the high cost and human resources. The video surveillance system should actively respond to detect crime and accidents in advance through real-time monitoring and immediately transmit data in case of an accident. This study proposes developing an intelligent video surveillance system that can actively monitor in real-time without human input. In solving the problems of the existing video surveillance system, deep learning technology will be carried through the data processing model design to visualize data for crime detection after building an artificial intelligence server and video surveillance camera. In addition, this design proposes an intelligent surveillance system to quickly and effectively detect crimes by sending a video image and notification message to the web through real-time processing.

As the fourth industrial revolution has been emerging, there are concerns of labor forces being replaced by technology, recent interest on the work-life balance, and the quality of employment has received attention. This study investigates the role of technology startups on employment and innovative performance. Using empirical data from workplace panel data provided by the Korea Labor Institute, this study reveals that technology startups impact the employment quality and innovative performance by the action of technological innovation. The results highlight the quality of employment as a driver for innovative performance in technology startups. The results of this study will provide practical implications for enhancing technology entrepreneurship.

The purpose of this study is to identify the difference in firm performance and employment growth between successful and failed capital procurement through equity-based crowdfunding. We conduct an empirical analysis using entire crowdfunding projects that attempted to raise capital through equity-based crowdfunding in South Korea in 2016. We summarize our findings as follows. Descriptive statistics show that the survival rate, sales growth rate, profitability growth, absolute employment growth, and employment growth rate of companies with successful crowdfunding are higher than those of companies with failed crowdfunding. However, from the difference analysis, we do not find a significant difference in the survival rate, sales growth rate, and profitability growth between companies with crowdfunding success and companies with crowdfunding failure. We find that the absolute employment growth and employment growth rate are significantly higher for companies that succeeded in crowdfunding projects compared to companies that did not. In this study, we find that the characteristics of these firms that are conducting or verifying new projects through equity-based crowdfunding financing are similar to those of prior studies results confirming the short-term effects of entrepreneurial activities or new business activities on economic performance and employment growth. In particular, it is very meaningful to confirm that the direct effect of employment growth is also found in start-up firms that raise capital through equity-based crowdfunding. By investigating the difference in firm performance and employment outcomes according to the results of equity-based crowdfunding investment, this study provides useful insights to investors for their efforts to validate participation in crowdfunding. Also, our study raises important policy implications for regulators in their efforts to resolve unemployment and the lack of capital problem for startups and new businesses.

This study aims to identify, from among business strategies presented in Miles and Snow (1978, 2003), those that increase the future performance or growth sustainability of unlisted small and medium-sized enterprises (SMEs) in Korea. (This study applied the scope of SMEs based on Article 2 of the Enforcement Decree of the Tax Exemption Restriction Act in Korea. The Korean tax law sets the scope of SMEs based on independence criteria set by the scale of sales, assets, and affiliation, and subordination. For example, the size standard of a manufacturing industry can be regarded as a small business if the average sales amount is less than 150 billion won or the total amount of assets is less than 500 billion won for three years.) In addition, it analyzes measured variables of business strategy for factors influencing unlisted SMEs’ future performance and growth potential. The objective is to determine a business strategy for unlisted SMEs, which are small, financially challenged, and have shorter lifespans and faster growth rates. The results highlight that investment in research and development (R&D) for new products influences both future performance and growth sustainability. R&D is an important intangible resource of the firm, which increases future risk due to high future uncertainty, but it is also an important factor to increase future performance or value based on resource-based theory. In the accounting field, research and development expenditure also provided evidence of future excess return or performance. This study is meaningful because it identifies the role of research and development in increasing future growth sustainability in SMEs, thus emphasizing change and innovation.

The purpose of this study is to verify the effectiveness of the entrepreneurship curriculum and the educational program recognized by students and graduates. This paper has studied the improvement of curriculum and educational programs operated by the Graduate School of Entrepreneurship by using Importance-Performance Analysis (IPA). This study was conducted on students and graduates who attended entrepreneurship graduate schools designated by the Ministry of SMEs and Startups (MSS) in Korea. The results of the questionnaire survey were tested the differences of curriculum courses by paired-sample t test and its improvement was analyzed through Importance-Performance Analysis (IPA). According to the research analysis, there was a difference in the preference of the curriculum and the educational program recognized by graduate students and graduates. The results of this study suggested academic and practical implications. In academic terms, this study classified the subject and educational curriculums of entrepreneurship graduate programs through the analysis of importance-satisfaction. In practical terms, this study suggested implications for the improvement of curriculum and educational programs for the activation of entrepreneurship graduate schools.

Sustainability and entrepreneurship are often regarded as binary concepts that have a tradeoff relationship, meaning that the higher the social and environmental consideration, the lower the private and economic benefits. The purpose of this study is to investigate the effect of individual sustainability orientation on opportunity recognition and sustainable entrepreneurship intention, and examine whether it has a tradeoff relationship with entrepreneurship orientation. The result of this study shows that sustainability orientation has a positive relationship with opportunity recognition and entrepreneurship intention related to sustainability. Analysis of the moderating effects of entrepreneurship orientation reveals the positive effect with sustainability orientation but negative effect with opportunity recognition on sustainable entrepreneurship intention. This study would suggest implications to entrepreneurs on how to balance sustainability and entrepreneurship and promote sustainability entrepreneurship.

Social media platforms are an indispensable part of entrepreneurship practices. They offer entrepreneurs a platform for business growth and brand development. However, little is known about the effect of social media use on identifying entrepreneurial opportunities. Utilizing social cognition theory, this research focuses on how certain factors—prior knowledge, alertness, and social media—may impact two aspects of opportunity: the discovery and the creation of entrepreneurial opportunity. This study focuses on the investigation of the moderating role of social media use on entrepreneurial opportunities. The findings have important practical and academic implications for how social media impacts entrepreneurship and can be used to increase the ability of entrepreneurs to find new opportunities.
