  • The prolonged coronavirus 19 (COVID-19) has caused serious problems such as job losses and youth unemployment, but as the fourth industrial revolution and digital transformation accelerate, the importance of SW is highlighted and more qualified jobs are expected in the SW industry. However, domestic SW companies are having difficulties in not properly recognizing the value of SW products. Among many related issues, commercial SW maintenance-related issues are representative, and the main problem is the difference in the maintenance fee rates between domestic and foreign SW. In this study, the expected job creation effect when the SW maintenance rate is raised was analyzed using data related to the SW industry and commercial software. As a result of the analysis, the amount required to raise the commercial SW maintenance rate by 1% is 162 billion won. If all of these are used for employment, the expected new job creation effect is 3,240 jobs per year, and 15,451 jobs are created per year when calculated and estimated as the effect of increasing sales through the employment inducement coefficient. In addition, the amount required to raise the current average maintenance rate of 11.1% to 15% is 631.9 billion won, and it was possible to estimate the effect of creating jobs for 12,648 people based on the simple average wage and 60,259 people from the sales increase effect.

  • Quality and sensory characteristics of tofu prepared with concentrated to 8 $^{\circ}Brix$ deep ground sea-like water (SW) were investigated to check the availability for coagulants. The tofu was coagulated with three kinds of commercially coagulant, such as $MgCl_2$, $CaSO_4$ and glucono-${\delta}$-lactone. Different amounts of SW and soybean milk were added: SW-20 g/L, SW-25 g/L and SW-30 g/L. The moisture content and pH were significantly lower in which preparation with glucono-${\delta}$-lactone coagulated tofu, and others has not significantly difference each other. The mineral contents in the coagulant influenced the mineral content of the tofu, which contained larger quantities of major minerals. However, the mineral content of the tofu was not affected of the mineral concentration in the coagulant. The L and b values of the tofu prepared with SW were not significantly different. The hardness of the tofu prepared with the commercial coagulants was significantly lower than that of the tofu produced with the SW. The sensory property was lower when the hardness was lower and higher. In conclusion, the quality characteristics of SW-prepared tofu were not significantly different from those of the tofu prepared with the commercial coagulants, but the texture and the taste of the SW-prepared tofu were excellent.

  • In this paper, a novel concept based on embedded processor and reconfigurable logic is proposed for efficient manufacturing test and design verification. Unlike traditional gap between design verification and manufacturing test, proposed concept is to combine both design verification and manufacturing test. The semiconductor chip which is using the proposed concept is named "SwToC" and SwToC stands for System with Test On a Chip. SwToC has two main features. First, it has functional verification function on a chip and this function could be made by using embedded processor, reconfigurable logic and memory. Second, it has internal ATE on a chip and this feature also could be made by the same architecture. To evaluate the proposed SwToC, we have implemented SwToC using commercial FPGA device with embedded processor. Experimental results showed that the proposed chip is possible for real application and could have faster verification time than traditional simulation method. Moreover, test could be done using low cost ATE.

  • Bacillus SW1-1 is a probiotic isolated from shrimp intestines. We investigated the effects of Bacillus SW1-1 coated diets on the growth, feed utilization, innate immunity, hematological parameters and resistance to Edwardsiella tarda in olive flounder (Paralichthys olivaceus). A commercial diet was used as the control (AP0) and two other diets were prepared by coating 0.25% (AP25) or 0.50% (AP50) probiotic powder which contains 1.0 × 107 CFU/g Bacillus SW1-1. Four replicate groups of olive flounder (153 ± 2 g) were fed one of the diets for 12 weeks. Growth performance and feed utilization of the fish were not significantly affected by the dietary Bacillus SW1-1. After the challenge with E. tarda, AP50 group showed significantly higher survival than AP0 and AP25 groups. Innate immunity and anti-oxidant capacity of the fish were not significantly affected after the feeding trial. However, after the E. tarda challenge, the innate immune parameters (immunoglobulin, lysozyme and anti-protease) were significantly improved in fish fed AP25 and AP50 diets compared to those in fish fed AP0 diet. After the challenge test, significantly lower glucose level was observed in AP50 group compared to AP0 group. These results indicate that dietary supplementation of Bacillus SW1-1 could increase the disease resistance of olive flounder against E. tarda infection. The optimum coating levels of Bacillus SW1-1 needs to be further elucidated.

  • The heartwood (HW) of Japanese cedar (Cryptomeria japonica) has usually a reddish color. But some trees have black-colored heartwood (BHW). BHW of Japanese cedar has a low commercial value because of the appearance. Therefore, in this study, a comparative analysis was conducted to evaluate the differences in the physical, mechanical, and inorganic element properties, and decay resistance of red-colored heartwood tree (RHW) and BHW. The physical properties showed significant difference between sapwood (SW) and HW, but there was no significant difference between RHW and BHW. From the results of mechanical properties, no significant difference was recognized in SW of RHW, HW of RHW, SW of BHW, and HW of BHW. There were decay resistance differences between RHW and BHW in HW, and between HW and SW in both RHW and BHW, respectively. The magnesium (Mg), potassium (K), and calcium (Ca) contents had significant differences between SW and HW in both RHW and BHW. In this present study, the decay resistances and the contents of Mg and K were higher in HW than in SW both for RHW and BHW, while these measurements were lower in RHW than in BHW. Therefore, BHW was considered to be worthy as a high-quality material as RHW.

  • A total of 94 tomato accessions were evaluated for the resistance to $Tomato$ $spotted$ $wilt$ $virus$ (TSWV) using a Sw5-2 SCAR marker and bioassay. PCR products of the marker were approximately 574 bp, 500 bp, and 462 bp, among which the longest was linked to TSWV resistance allele of Sw5-b. This allele was only found in three accessions (09-438, 10-318, and 10-321) in which some individuals showed apparent recovery or stem necrosis symptom to a tomato isolate of TSWV-pb1. Thirty-five individuals (one per each accession) which were non-infected by ELISA were selected for further observation. Among these, 26 individuals that did not show any symptom at 5 months after inoculation were confirmed for viral infection by RT-PCR. TSWV-specific PCR amplicon was weakly detected in all 26 individuals including 'Eureta', a commercial F1 possessing the resistance allele of Sw5-b. The resistant genes in the selected individuals may play an important role for reducing the viral concentration in tissues of inoculated tomato plants and seems to be quantitatively controlled by several factors including Sw5-b gene.

  • As the complexity of SoC (System-on-Chip) design increases dramatically. traditional system performance analysis and verification methods based on RTL (Register Transfer Level) are no more valid for increasing time-to-market pressure. Therefore a new design methodology is desperately required for system verification in early design stages. and hardware software (HW-SW) cosimulation at TLM (Transaction Level Modeling) level has been researched widely for solving this problem. However, most of HW-SW cosimulators support few restricted ion levels only, which makes it difficult to integrate HW-SW cosimulators with different ion levels. To overcome this difficulty, this paper proposes a multipurpose framework for HW SW cosimulation to provide systematic SoC design flow starting from software application design. It supports various design techniques flexibly for each design step, and various HW-SW cosimulators. Since a platform design is possible independently of ion levels and description languages, it allows us to generate simulation models with various ion levels. We verified the proposed framework to model a commercial SoC platform based on an ARM9 processor. It was also proved that this framework could be used for the performance optimization of an MJPEG example up to 44% successfully.

  • Tomato spotted wilt virus (TSWV) causes one of the most destructive viral diseases that threatens global tomato production. Sw-5b was reported as the resistance gene effective against TSWV. The objective of this research was to develop a single-nucleotide polymorphism (SNP) marker to distinguish tomato cultivars resistant to TSWV from susceptible cultivars for marker-assisted breeding. First, we determined genotypes for TSWV resistance in 32 commercial tomato cultivars using the previously reported Sw-5b gene-based marker. Then, DNA sequences of Sw-5b alleles in tomato cultivars showing resistant or susceptible genotypes were analyzed; a single SNP was found to distinguish tomato cultivars resistant to TSWV from susceptible cultivars. Based on the confirmed SNP, a SNP primer pair was designed. Using this new SNP sequence and high-resolution melting analysis, the same 32 tomato cultivars were screened. The results were perfectly correlated with those from screening with the Sw-5b gene-based marker. These results indicate that the SNP maker developed in this study will be useful for better tracking of resistance to TSWV in tomato breeding.
