The possible application of Lactobacillus spp. as a functional starter culture to ferment galgeuntang (GT) and to produce bioactive isoflavone (daidzein) was investigated. Lactobacillus casei KFRI 127, L. plantarum KFRI 144, L. bulgaricus KFRI 344 were used for GT fermentation. Acid development and quantification of isoflavones using high-performance liquid chromatography were performed after fermentation at 37$^{\circ}C$ for 48 h. All the tested Lactobacillus spp. lowered pH to about 3.8 in 48 h and L. plantarum KFRI 144 exhibited 89.9% hydrolysis rate of daidzin (79.1-8.0 ${\mu}g$/mL) during fermentation. The content of daidzein in GT fermented with L. plantarum KFRI 144 was increased by 6.6-fold (3.6-23.9 ${\mu}g/mL$). These results demonstrate that L. plantarum KFRI 144 has potential as functional starter culture for manufacturing fermented GT with higher isoflavone bioavailability.

This study analyzed the factors that influence the domestic SMEs that have introduced smart factories on their intention to accept at a higher level for qualitative advancement. 375 copies collected through an online survey were analyzed using SPSS and AMOS with UTAUT and the extended two-stage information system continuous model. Performance expectancy, effort expectancy, social influence, and facilitating conditions have a statistically significant effect on user satisfaction and user satisfaction and CEO's will have an effect on the intention to accept the advancement. However, the suppliers' technology didn't have a direct effect on the advancement acceptance intention and user satisfaction has a mediating effect between performance expectancy, effort expectancy, social influence, facilitating conditions and the advancement acceptance intention. SME's advancement for smart factory, it is important to improve the satisfaction level and the CEO's will to become smart.

This paper is a survey on the advancement of virtualization technology. Virtualization of resources was an inevitable path in modern computer systems. This abstraction of hardware allowed the decoupling of the operating system that manages the hardware and applications' requirements by adding a layer between them. It also led to the application-centric view of computing and light virtual machines, where each represents a computer networking device. As virtualization technology ripens, the performance of virtual machines can only improve. This paper will be introducing how virtualization technology has evolved from Xen to LightVM and Firecracker.

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.

Availability of defect test algorithm that recognizes exact and standardized defect information in order to fundamentally resolve generated defects in industrial sites by giving artificial intelligence to SAT(Scanning Acoustic Tomograph), which previously depended on operator's decision, to find various defect information in a semiconductor package, to decide defect pattern, to reduce personal errors and then to standardize the test process was verified. In order to apply the algorithm to the lately emerging Neural Network theory, various weights were used to derive results for performance advancement plans of the defect test algorithm that promises excellent field applicability.

Recently, due to the increasing necessity of developing core parts for weapons systems, the project for localization of parts for weapons systems is expanding. In order to apply the developed core parts to the domestic weapon system and advance into the overseas market, it is necessary to plan a project that reflects the technology trends in advance. This study derived trend of technology development through conducting the patent research and analysis. Also, suggested plan for applying the analysis results when project planning and selecting. As a detailed method, patents related to the 2019 year selection project were investigated. The number of patent applications by year and number of applicants from the time of the first application to the present were analyzed. And the growth stage of the technology market was derived. The comprehensive result was derieved through the portfolio analysis by arranging the parts localization technology in each area of the matrix consisting of market growth stage and the criteria for the selection of parts localization project. This research suggested the applying plan for improving project selection process. we expect the promotion of defense industry and the effective task planning.
