The purpose of this study is to investigate the transitory and permanent growth effects of human capital of the Korean economy based on the analysis of the New Normal Era during the period 1970-2014. For the transitory effects, we found out that all the coefficients of capital and labor are significant above the 5% level, whereas the coefficients of labor and human capital are significant only at the 10% level during the period 1999~2014. In particular, in the case of 1% increase in the human capital, the actual growth rate raised up with the rate of 0.15% over a 45-year period. For the permanent growth effects, the coefficients of capital and labor are significant above the 5% level. Furthermore, sum of the coefficients of the capital and labor showed approximately 0.96~0.99, approaching to a unit, which implies that there is a constant returns scale with respect to these inputs. In particular, the coefficient of human capital at 0.064 is significant at the 10% level. This implies that the permanent growth effect of an additional index of human capital is about 0.64% the previous 45-year period.

This paper begins with the question of whether "on-tact" Christian education, which has become the most new-normal phenomenon since Corona 19, will remain as a decisive form of Christian education even in the post-Corona era. In order to answer that question, this study explored whether on-tact Christian education has its own domain of experience and educational elements that cannot be replaced by face-to-face education, specifically focusing on "types of on-tact Christian Education", "discussion of digital church" and "digital epistemology". Through research on "types of onn-tact Christian education," it confirmed that, when viewed on the basis of 'participation' or 'communication', on-tact Christian education has an independent field of experience and educational elements. Through contemplation on "digital ecclesiology", it found that on-tact education is the decisive channel for Christian education to reach digital generation. It also found a new metaphor from the "network" concept for the public church and the Kingdom of God. This paper also found that we experience the perception of the body that is expanded through the combination between the body and technology in the digital world, and that this is a unique epistemology that occurs only in the digital world. Based on the above points, it affirmed that on-tact Christian education is not simply a means of supplementing face-to-face education in the era of COVID-19, but is a Christian education that has an independent field of experience and educational power that face-to-face education cannot replace. Thus it foresees that on-tact Christian education will continue to expand as a center and form of Christian education even in the post-corona era.

In this study, detailed factors of public sentiment toward the 'post-corona new normal' were examined through social media big data sentiment analysis. Thus, it is to provide basic data to preemptively cope with the post-COVID-19 era. For data collection and analysis, the emotional analysis program of 'Textom', a big data analysis program, was used. The data collection period is one year from October 5, 2020 to October 5, 2021, and the collection channels are set as blogs, cafes, Twitter, and Facebook on Daum and Naver. The original data edited and refined a total of 3,770 collected texts from this channel were used for this study. The conclusion is as follows. First, there is a high level of interest and liking for the 'post-corona new normal'. In other words, it can be seen that optimism such as daily recovery, technological growth, and expectations for a new future took the lead at 77.62%. Second, negative emotions such as sadness and rejection are 22.38% of the total, but the intensity of emotions is 23.91%, which is higher than the ratio, suggesting that these negative emotions are intense. This study has a contribution to the detailed factor analysis of the public's positive and negative emotions through big data analysis on the 'post-corona new normal'.

The COVID-19 pandemic has been reshaping the world by accelerating non-contact services and technologies in various domains. Hospitals as a healthcare system lie at the center of the dramatic change because of their fundamental roles: medical diagnosis and treatments. Leading experts in health, science, and technologies have predicted that robotics and artificial intelligence (AI) can drive such a hospital transformation. Accordingly, several government-led projects have been developed and started toward smarter hospitals, where robots and AI replace or support healthcare personnel, particularly in the diagnosis and non-surgical treatment procedures. This article inspects the remaining element of healthcare services, i.e., surgical treatment, focusing on evaluating whether or not currently available laparoscopic surgical robotic systems are sufficiently preparing for the era of post-COVID-19 when contactless is the new normal. Challenges and future directions towards an effective, fully non-contact surgery are identified and summarized, including remote surgery assistance, domain-expansion of robotic surgery, and seamless integration with smart operating rooms, followed by emphasis on robot tranining for surgical staff.

The purpose of this study is surveyed 109 vegan diet practitioners in their 20s or older to inform the need for research and development to include the oral health area in the health trend of vegan. Frequency analysis, X²,and simple linear regression analysis were performed using SPSS. The vegan group, which is fully vegetarian, had a lower risk of subjective dental caries, but the perception of subjective oral health was negative. It was found that vegan dietary habits were believed to be a little more beneficial in terms of oral health, but were perceived as vulnerable in actual oral health. Based on these results, it is believed that it is necessary to develop an oral-nutritional program that reflects a new dietary consumption trend called vegan in the new nomal.

The purpose of this study is to examine the impact of enterprise R&D investment on inter-industry technology spillover in Korea under the new Normal Era. In order to do this, we tested the effect of production inducement, backward and forward linkage effects, and the effect of technology spillover such as technology intensity effects and technology diffusion effects based on an input-output framework. The results show that the high index industries of the production inducement effect were professional, scientific and technical activities, manufacture of metal products, and general machinery. Some manufacturers of other non-metallic mineral products and transport equipment sectors appeared to have the strong effect of forward and backward linkages that were almost equivalent to high-tech manufacturing industries. In particular, the industries of professional, scientific and technical activities appeared to have the strong effect of both forward and backward linkages. Therefore, we need to drive a strong policy support to higher enterprise R&D investment in the those particular industries not only to increase global competitiveness, but also to widen up the technology spillover effect on other industries.

Because of the advantages of certificateless and no escrow feature over the regular signature and identity-based signature, certificateless signature has been widely applied in e-business, e-government and software security since it was proposed in 2003. Although a number of certificateless signature schemes have been proposed, there is only one lattice-based certificateless signature scheme which is still secure in the quantum era. But its efficiency is not very satisfactory. In this paper, the first certificateless signature scheme on NTRU lattice is proposed, which is proven to be secure in random oracle model. Moreover, the efficiency of the new scheme is higher than that of the only one lattice-based certificateless signature.

In this viewpoint paper, we overlook the potential of the data industry and the strategies needed in order to survive in this new socio-economic order brought by COVID-19. The social distancing culture is leading to the expansion and centralization of data. The government established the development plan of the data industry ecosystem and the capital flow is following this stream, so this is an opportunity for those in the data business. To survive and grow in the data industry ecosystem, we need to identify quality characteristics that have a comparative advantage over competitors based on high data quality and need to determine the target business segmentation to avoid wasting resources and make efficient investments.
