The present paper computes the refractive indices of different corona viruses (H5N1, H5N2, H9N2, H4N6, FAdV and IBV) through reflectance analysis of a virus solution. The computational analysis indicates that the refractive indices of all viruses are negative at the signal of 412 nm. Further the numerical output shows that the infectious bronchitis viruses (family of novel corona viruses, COVID-19) have higher negative refractive indices as compared to other corona viruses. Finally refractive indices of the family of COVID-19 are investigated with respect to the EID (Electronic infusion Device) concentration of the viruses, showing that the refractive index which ranges from "-0.96725 to -0.999998" corresponds to '0.01 to 10000' EID virus concentration.

Present computing power and enhanced technology is progressing at a dramatic rate. These systems can unravel complex issues, assess and control processes, learn, and-in many cases-fully automate production. There is no doubt that technological advancement is improving many aspects of life, changing the landscape of virtually all industries and enhancing production beyond what was thought possible. However, the human is still a part of these systems. Consequently, as the advancement of systems transpires, the role of humans within those systems will unavoidably continue to adapt as well. Due to the human tendency for error, this technological advancement should compel a persistent emphasis on human error reduction as part of maximizing system efficiency and safety-especially in the context of the nuclear industry. Within this context, as new systems are designed and the role of the human is transformed, human error should be targeted for a significant decrease relative to predecessor systems and an equivalent increase in system stability and safety. This article contends that optimizing the roles of humans and machines in the design and implementation of new types of automation in nuclear facility systems should involve human error reduction without ignoring the essential importance of human interaction within those systems.

본 연구는 벤처캐피탈 투자가 중소벤처기업의 기술적 성과(특허)에 미치는 영향을 분석하였으며 분석결과는 다음과 같다. 벤처캐피탈 투자지분율이 높을수록, R&D집약도가 높을수록 기술적 성과에 정(+)의 영향을 미치는 것으로 나타났다. 또한 벤처캐피탈이 공동투자한 기업 또는 투자지분율이 월등하게 높은 리딩(leading) 투자자가 있는 투자기업의 경우에도 기술적 성과가 정(+)의 결과를 보이고 있다. 그러나 기업규모가 클수록, 기술인력이 많을수록 기술적 성과가 정(+)의 결과를 보이고 있으나 유의하지 않았다. 이는 벤처캐피탈의 투자기업에 대한 모니터링과 통제 그리고 경영 또는 기술적 지원이 효과를 발휘하고 있거나 다른 투자자들의 검증을 받은 기업 또는 비교적 안정적인 기업에 투자가 집중된 결과로 해석할 수 있다.

Purpose - The purpose of this paper is to examine the welfare effects of standards harmonization between technologically asymmetric countries, and to determine optimal harmonization strategies for a country with mid-level technological advancement. Design/methodology - Following Salop's circular city model (Salop, 1979), this study constructs a simple, horizontally-differentiated oligopoly model in which three firms and three countries exist. Each country adopts different compatibility standards and each firm incurs conversion costs for foreign market access due to differences in standards. The conversion costs are related to technology; standards harmonization removes these costs between participating countries. The paper considers three cases: i) no harmonization; ii) harmonization with the more technologically-advanced country and iii) harmonization with the less technologically-advanced country. Findings - The paper first considers a scenario in which all three firms occupy some share of the market in each country. It shows that standards harmonization with both the technologically moreor less-advanced country always increases consumer surplus and social welfare. In addition, the producer surplus will increase if the harmonization partner has a higher technology level, whereas it may decrease if the partner has a lower technology level. It also shows that if most domestic export goods are in sectors with conversion costs above a certain level, harmonizing standards with a technologically more-advanced country should be prioritized. Such strategies, moreover, should be emphasized when there exists a large technology gap among countries. Lastly, the paper considers another scenario, in which harmonization leads to the foreclosure of the non-member firm from the member countries' markets. It shows that harmonization improves the social welfare of a mid-level technology country regardless of its partner's technology. It also shows that the country should prioritize harmonization with the technologically less-advanced country. Originality/value - Though some of the existing studies consider the welfare effects of harmonization, their main assumption is that firms have the same conversion technology. Since complying with standards often requires substantial technological advancement and technical expertise, harmonization of compatibility standards between countries with gaps in technological ability carries different implications. This paper investigates the welfare effects of this harmonization and determines an optimal harmonization strategy while considering technological asymmetry among countries in standards compliance.

Purpose This research aims to investigate factors affecting the application of strategic management accounting in Vietnamese Logistics Enterprises. Design/Methodology/Approach: Quantitative research was conducted and data was collected by sending questionnaires to 188 accountants and directors from Vietnamese Logistics Enterprises (including, transportation, warehousing and forwarding). 5 factors (namely: size and organizational structure, technological advancement, and strategic management accounting implementing costs) were selected to measure the application of strategic management accounting (SMA) in Vietnamese Logistics Enterprises (LEs) through correlation and regression analysis. Results: The empirical findings show that there exists a significant association between these factors and the SMA application. LEs have strongly supported the application of SMA as a tool to provide information for making their strategic decisions. The factors including size and organizational structure, technological advancement, SMA implementing c osts, and strategy positively impact the SMA application in both financial and non-financial aspects. This finding helps the adm inistrators realize the importance of SMA. Conclusions: This study provided an overview of SMA application and its benefits to enterprises. It helps managers have a better understanding of SMA and future directions for application. Moreover, the research results will be useful for managers to identify factors influencing their SMA practices and improve the current management process applied in organizations.

The mobile payment system has not only changed the payment pattern but also has improved the performance of small and medium-sized enterprises (SMEs) and individuals' quality of life by saving their energy, reducing the risk of taking cash, and enabling them to give more time to businesses and do international business. Besides, with the current advancement in the Internet as well as the digital transformation, SMEs are being forced to adopt mobile payment systems (MPS). The purpose of this study is to investigate the effects of technological-organizational-environmental (TOE) determinants on the adoption of MPS and its impact on SMEs' firm performance operating in Ghana. This research employed a closed-ended questionnaire to collect data from January 2020 - April 2020. This study used a structural equation modeling (SEM) approach using SmartPLS 3.0 for path analysis of 145 responses. The findings of the study include the statistically significant effects of technological (relative advantage and compatibility), organizational (top management support and employees' readiness), and environmental (social influence and competitive pressure) factors on the adoption of MPS. Furthermore, this study also proved the positive and statistically significant effect of MPS on SMEs' performance. This study demonstrated that the TOE factor explains 70% variations in the adoption of MPS.

군사적 기습의 한 유형인 기술적 기습은 현대 과학기술의 급진전과 함께 다양하게 활용되고 있으며, 전술적 차원과 전략적 차원에서 사용되어 진다. 현대 과학기술은 전쟁의 수단인 무기체계에 커다란 변화를 가져옴에 따라, 기술적기습의 가능성은 더욱 증가하고 있다. 기술적 기습은 새로운 신기술의 채택, 기존 기술의 신속한 전력화, 그리고 기존 기술이나 무기의 운용방법을 혁신하는데서 기인한다. 이러한 기술적 기습은 두 가지로 분류된다. 이미 기술적 충격으로 다가올 것으로 예견하였지만 충분히 대비하지 못하였거나 대응하기에 시간이 부족한 '알려진 기술적 기습'과, 기습이 발생할 것이라고 조금은 인지하였지만 다른 중요한 기습에 대비하느라 묻혀버린 '생소한 기술적 기습'이다. 이러한 기술적 기습에 대한 사례로서 현대에 발생한 주요한 기술적 기습 9가지를 제시하고 분석하였다. 향후 한국군이 기술적 기습에 대한 대비해야 할 방향으로는 기술적 기습을 담당할 국방 조직의 설치, 기술적 기습에 대한 관리 체계 구축, 그리고 미래 기술적 기습을 생산해 낼 수 있는 군사기술의 혁신이 필요하다.
