For smart defense innovation, the key is to apply state-of-the-art technologies of the Fourth Industrial Revolution to national defense. In order to apply state-of-the-art technology to the defense sector, we need to apply and develop technologies to analyze and respond to uncertain future operational environments. To this end, our military is investing a lot of time and effort. To understand future operational environment analysis and to apply and develop our military, we explored the perspectives of operational environment analysis in major countries and studied specific cases of U.S. troops with systematic analysis functions. The U.S. Army has established a cooperative system to analyze future operational environment under the leadership of the Education Command and operates the organization organically. It also utilizes the collective intelligence of expert groups in various fields by utilizing the MSC, and it is time for the Korean military to take the lead in keeping with the era of transformation. To that end, the organization of the U.S. Education Command should be benchmarked and the Korean Future Operation Environment Analysis Organization should be established and operated. Through this study, we have developed an understanding of the future operational environment analysis system of the U.S. Army and presented a plan to apply the ROK MND.

Chicken skins or carcasses inoculated with Salmonella typhimurium were exposed to 0.1 or 0.5% grapefruit seed extracts (DF-100) for 1 or 3 min to evaluate antibacterial activity of DF-100 and its possible application in proultry processing. The numbers of live salmonellae on chicken skins were reduced by 0.8-1.2 logs/cm2 with 0.5% DF-100. Dipping chicken carcasses into 0.5% DF-100 for 3 min reduced salmonelae by 4.3 logs/carcass. Scanning electron microscopy showed that DF-100 killed the cells attached but did not detach cells from the skin. No odor or changes in the color of chicken skin were detected after DF-100 treatment.

A distance protection algorithm for detecting faults at power transmission lines is presented in this paper. The algorithm is based on the differential equation related to the voltage and the current at an equivalent circuit of a transmission line which is composed of the lumped resistance and inductance. The presented integration method has high performance at though the fault voltage and the current are heavily distorted with the DC offset and harmonics which occurred at transient states after faults.

The purpose of this study was to identify U.S. consumers' preferences for Bibimbap and to determine whether or not Bibimbap can be adopted into the American palate. A total of 214 people tasted a controlled amount of Bibimbap and Gochujang sauce (red chili pepper sauce) and then completed a preference test. Bibimbap was highly rated overall in the areas of appearance, color, smell, and taste. Gochujang sauce was also well-accepted in terms of taste and spiciness. Most of the participants disliked the seaweed and shiitake mushrooms, which means that Bibimbap can improve its garnish taste and aroma by removing them. Further, a more watery sauce was served as foreigners are not familiar with mixing food culture. Therefore, by offering diverse ingredient options, the acceptance of traditional Bibimbap can be increased in the U.S.

A decade has passed since the first generation of Genesis was launched in the U.S. with the plaque of Hyundai-Genesis. Genesis Motors was separated from Hyundai Motor in 2015, and has struggled to have the Genesis stand alone in the competitive U.S. luxury sedan market. The present case study aims to find challenges facing the Genesis, which Hyundai has positioned as a luxury sedan competing against conventional luxury brands such as BMW, Mercedes-Benz, and Lexus; evaluate Genesis Motors' strategic response to meet these challenges; and explore an alternative positioning strategy. Specifically, the present case study addresses barriers against the Genesis' market performance, by focusing on the obstacles rooted in the consumer perception as well as the obstacles that stem from the change in the U.S. automobile industry and the nascent network of the Genesis dealership. Genesis Motors' current strategies are evaluated, and an alternative strategy is explored that is largely based on the American consumers' perceptions of the Genesis vis-a-vis conventional luxury brands and outperforming midsize brands.

Environmental management systems offer a set of management tools and principles that can help integrate environmental concerns into daily business practices. Such systems have been in existence since the 1980's. This research identifies the firm's implementation of environmental management that is the most and least popular for managing the environmental management such as 3R's, EM, EMS, environmental awareness. This article investigates the differences of managing to environmental issues of firms between Korea and U.S. The research results suggest that the U.S. firms control of 3R's, EM and EMS better than Korea's, while Korean firms have higher environmental awareness than U.S. firms.

This paper presents an investigation into cross-cultural transfiguration of Buddhist faith in Goryeo Dynasty, with a focus on $\acute{S}\bar{u}$raṃgama-s$\bar{u}$tra that used to be in vogue in East Asia. There are three major types of $\acute{S}\bar{u}$raṃgama-s$\bar{u}$tra faith in Goryeo: the first one was concerned about the scripture itself including its citation and publication and the compilation of its annotation books; the second one involved establishing Buddhist rituals related to the scripture; and the final one was to create Dh$\bar{a}$ran$\bar{i}$ stone poles with Dafoding Dh$\bar{a}$ran$\bar{i}$ in Volume 7 of the scripture engraved in stone. While it was the common practice to engrave Zunsheng Dh$\bar{a}$ran$\bar{i}$ in China, the number of stone poles on which Dafoding Dh$\bar{a}$ran$\bar{i}$ was engraved was overwhelmingly large. There are a couple of reasons behind the difference: first, there was a tendency of Zunsheng Dh$\bar{a}$ran$\bar{i}$ being worshiped at the national level in Goryeo, which probably explains why the percentage of Zunsheng Dh$\bar{a}$ran$\bar{i}$ stone poles designed to pray for a personal mass for the dead by engraving Dh$\bar{a}$ran$\bar{i}$ on a stone pole was considerably low. In addition, there were esoteric sects in Goryeo, and it is estimated that they must have got involved in the establishment of Dafoding Dh$\bar{a}$ran$\bar{i}$ stone poles in the former half of Goryeo. Furthermore, the Zen sects had a deep non-Zen understanding of Esoteric Buddhism and tended to practice Dh$\bar{a}$ran$\bar{i}$ in Goryeo. It is estimated that Dafoding Dh$\bar{a}$ran$\bar{i}$ stone poles were set up in large numbers in Goryeo as the prevalence of $\acute{S}\bar{u}$raṃgama-s$\bar{u}$tra faith that continued on since the former half of Goryeo was combined with the Zen sects' active position about Dh$\bar{a}$ran$\bar{i}$.

The submerged U-shape breakwater interaction with the solitary wave is simulated by the Boussinesq equations using the finite-difference scheme. The wave reflection, transmission, and dissipation (RTD) coefficients are used to investigate the U-shape breakwater's performance for different crest width, Lc1, and indent breakwater height, du. The results show that the submerged breakwater performance for a set of U-shape breakwater with the same cross-section area is related to the length of submerged breakwater crest, Lc1, and the distance between the crests, Lc2 (or the height of du). The breakwater has the maximum performance when the crest length is larger, and at the same time, the distance between them increases. Changing the Lc1 and du of the U-shape breakwaters result in a significant change in the RTD coefficients. Comparison of the U-shape breakwater, having the best performance, with the averaged RTD values shows that the transmission coefficients, Kt, has a better performance of up to 4% in comparison to other breakwaters. Also, the reflection coefficients KR and the diffusion coefficients, Kd shows a better performance of about 30% and 55% on average, respectively. However, the model governing equations are non-dissipative. The non-energy conserving of the transmission and reflection coefficients due to wave and breakwater interaction results in dissipation type contribution. The U-shape breakwater with the best performance is compared with the rectangular breakwater with the same cross-section area to investigate the economic advantages of the U-shape breakwater. The transmission coefficients, Kt, of the U-shape breakwater shows a better performance of 5% higher than the rectangular one. The reflection coefficient, KR, is 60% lower for U-shape in comparison to rectangular one; however, the diffusion coefficients, Kd, of U-shape breakwater is 35% higher than the rectangular breakwater. Therefore, we could say that the U-shape breakwater has a better performance than the rectangular one.
