Due to the rapidly ageing population and low birth rates, most countries have faced with the problems of an ageing population. As a result, research into aging and the means to support an aging population has therefore become a priority for many governments around the world. Ambient Assisted Living(AAL) approach is the way to guarantee better life conditions for the aged and for monitoring their health conditions by the development of innovative technologies and services. AAL technologies can provide more safety for the elderly, offering emergency response mechanisms and fall detection solutions. Since the information transmitted in AAL systems is very personal, however, the security and privacy of such data are becoming important issues that must be dealt with. In this paper, we propose a Chameleon hash-based secure authentication protocol for AAL systems. The proposed authentication protocol not only supports several important security requirements needed by the AAL systems, but can also withstand various types of attacks. In addition, the security analysis results show that the proposed authentication protocol is more efficient and secure than the existing authentication protocols.

The purpose of this study is to investigate the factors influencing the innovation resistance of cloud computing services and to suggest policy alternatives to increase the use of domestic cloud computing services. For this, a survey was conducted on 178 SMEs that introduced cloud computing services with government support. As a result, technostress, CEO informatization leadership and organizational structure concentration had a significant influence on innovation resistance. Therefore, in the future, first, it is necessary to provide user-centered cloud computing services in the direction of reducing technostress. Second, it is necessary to apply cloud computing services through a deeper understanding of the organizational characteristics of each small and medium enterprise. Third, there is a need for advanced security authentication and a compensation system. In order to promote the use of cloud computing services, an environment in which users can safely use should be prepared first.

Environmental and energy issues such as abnormal climate and depletion of fossil fuel due to global warming have emerged as a critical task to threaten human survival. As a result, interest in the Zero Energy Building is increasing as it is an innovative building that can significantly contribute to building energy reduction and greenhouse gas reduction. In the market, however, the added cost of construction is a major stumbling block to the revitalization of the Zero Energy certification. In this study, general private apartment complexes were selected for research, detailed elements for Zero Energy certification were presented based on the construction criteria for eco-friendly houses from the initial design stage, and the cost efficiency analysis of the components for certification were presented. It has been analyzed that only Grade 3 certification can be implemented in apartments due to technical level and physical limitations. Also, after reviewing the cost trend during the lifecycle cost, all expenses can be recovered within 13 years after completion only in the case of grade 5 of the Zero Energy Building. The additional costs proposed in the present study are reflected appropriately in the review of projects for apartments scheduled for order in the future to contribute to the revitalization of the Zero Energy Building certification.

This study is to confirm the core factors of innovative capabilities and technological entrepreneurship affecting the performance of technology management and business management of small and medium-sized enterprises (SMEs). Through the consideration about the complex natures of technological innovation affecting by multidimensional factors, this study designs the research model that innovative capabilities, the performances of technology and business management are arranged in accordance with the innovation process; input-output-outcome. To meet this research purpose, the hypothesis are set up based on the previous research studies and the research samples are selected from members of the Innovative Business (INNO-BIZ) Association, located in Seoul and Geyonggi province. As a result of regression analysis to the responses gathered from 360 firms, the performance of business management is influenced positively by the technology superiority, market growth and business profitability which are the dominant factors of performance of technology management. In addition, three sub-variables of innovative capabilities such as R&D, strategic planning and learning capability, have positive effects on both the managerial performances. Innovativeness and progressiveness of technological entrepreneurship affect both the performances positively. Moreover, the co-relation between technological entrepreneurship of an innovation leader and innovative capabilities of organizational members are identified. Lastly, technological entrepreneurship has the mediating effect on the path of leading innovative capabilities to the managerial performances. In conclusion, the research results imply that technological innovation-type firms should periodically evaluate the performance of technology management which are the output of technological innovations and the reinvestment for ultimate business success. And improving and developing innovative capabilities and technological entrepreneurship is required to continuously and consistently investing and supporting resources on technological innovations at the firm-and government-level. It is considered that these are the crucial methods for securing the technologically competitive advantage of SMEs with less resources and narrow innovation range.

This study has empirically analyzed the effect of government technology development supports on the performance of SME's (Small-and-Medium-Sized Enterprises). To analyze the effects of government technology development supports on the performance of SME's, this paper collected data from 271 Korean SMEs and tested hypothesis on the key questions. The result shows that government technology development supports had a meaningful positive effect on the performance of SMEs in terms of innovation. It was also understood that the closer the ties were with large enterprises, the higher the R&D personnel ratio was. Furthermore, when the SME was a certified venture, the government technology development supports had less influence on the SME's technological innovation. On the other hand, SME's technological innovation performance in relation to the government supports showed an improvement when the business environment of SME's was hostile. This study offers theoretical and practical implications, as it more accurately analyses the effect of government technology development supports on the performance of SME's, for which data were collected and analyzed for the same companies two separate times. Last of all, the limitation of this study is discussed in terms of the sample selection, data collection method, variables measurement method, etc.

As the Great Reset is discussed at the World Economic Forum due to the COVID-19 pandemic, artificial intelligence, the driving force of the 4th industrial revolution, is also in the spotlight. However, corporate research in the field of artificial intelligence is still scarce. Since 2000, related research has focused on how to create value by applying artificial intelligence to existing companies, and research on how startups seize opportunities and enter among existing businesses to create new value can hardly be found. Therefore, this study analyzed the cases of startups using the comprehensive framework of the multi-level perspective with the research question of how artificial intelligence based startups, a sub-industry of software, have different innovation patterns from the existing software industry. The target firms are gazelle firms that have been certified as venture firms in South Korea, as start-ups within 7 years of age, specializing in machine learning modeling purposively sampled in the medical, finance, marketing/advertising, e-commerce, and manufacturing fields. As a result of the analysis, existing software companies have achieved process innovation from an enterprise-wide integration perspective, in contrast machine learning technology based startups identified unit processes that were difficult to automate or create value by dismantling existing processes, and automate and optimize those processes based on data. The contribution of this study is to analyse the birth of artificial intelligence-based startups and their innovation patterns while validating the framework of an integrated multi-level perspective. In addition, since innovation is driven based on data, the ability to respond to data-related regulations is emphasized even for start-ups, and the government needs to eliminate the uncertainty in related systems to create a predictable and flexible business environment.

The Ministry of Agriculture, Forestry and Fisheries prepared the sixth industrialization certification system to increase the added value in the agricultural sector, but it is a bit hard to judge that the system has been in the stage of creating sufficient added value. In particular, because of the Fourth Industrial Revolution, there is a significant change in all industry sectors, including innovation in technology, and the change of perception among the society members is being rapidly changed toward the corporate sector's social role. Thus, we surveyed companies that received the sixth industrialization enterprise certificate to address this phenomenon and find clues on how to be competitive. We selected 800 companies certified by the Ministry of Agriculture, Forestry and Fisheries as sixth industrialization enterprises as our study samples. Among them, we subjected 275 respondents to a final analysis upon eliminating incomplete responses. The result of the study revealed that entrepreneurship, including autonomy that reflects the characteristics of the certified companies, had a significant positive impact on economic value. Moreover, with the size of the companies certified as the sixth industrialization enterprise and the industry trend toward the innovative Fourth Industrial Revolution considered, the strategic orientation including the customer orientation to intensively focus on customer needs and the technology orientation to accept technology as a competitive sector even in the agricultural industry was found to have a significant positive effect on economic value. Strategic orientation demonstrated a significant positive effect on social value. Entrepreneurship demonstrated a significant positive effect on economic values but did not significantly affect the social value. Lastly, while strategic orientation has demonstrated that no mediation effect resulted due to a high direct effect between entrepreneurship and economic value, a complete mediation effect occurred between entrepreneurship and social value. Based on this study, if the companies that received the sixth industrialization enterprise certificate are equipped with not only entrepreneurship but also strategic orientation for customer-oriented thinking and response to technological changes, they can become an influential element in creating not only economic value but also social value, which is emphasized as an element of sustainability.

Blockchain technology has the potential to revolutionize trust models and business processes in a variety of industries. However, it is considered to be the initial stage of the system that pursues autonomy rather than efficiency, and it is necessary to monitor and inspect the distributed ledger technology from the price and introduction time as compared with the existing relational DB transaction technology. However, domestic and foreign private sectors have already been activated by applying block-chain technology in the national domain, and the block chain is devoid of doubt that it is an exaggerated technology, characterized by the invariance of the record, transparency, and autonomous execution of business rules. It has begun to be utilized in history, identity, certification and auditing in the financial industry as well as various industries. In this paper, we analyze the problems such as security weakness, insufficient regulatory environment, technical consensus and lack of common standard. In addition, the business sense and possibility of the block chain technology is expected to be the innovation of the industrial ecosystem by entering into the reality system from the concept through monitoring the actual introduction performance in the field of copyright, logistics, health care and environment.
