This study is to determine the key factors of internal situational characteristics, affecting the motivation and performance for overseas expansion of Korean venture business in global markets and to investigate the moderating effect of them on the relationship between entrepreneurship and overseas expansion. To meet the research purpose, by reviewing previous researches, we categorized internal factors into four situational factors of firm size with sales growth, firm age with main product's life cycle, overseas experience and organizational structure and into three entrepreneurship sub-categories of innovativeness, pro-activeness and risk-taking. As result of the statistical analysis of 289 small and medium-sized enterprises with Korean Venture Certificate, it is verified that the motivation for globalization has been influenced by firm size, entrepreneurship, and overseas experience. On the other hand, all factors excepting firm size have positive effects on globalization performance overseas. And, it also verified that there are positive moderating effects of internal situational factors on the relationship of entrepreneurship and the performance of globalization, wheres overseas experience only plays positive moderating effects on the relationship between entrepreneurship and the motivation of globalization. On the basis of these results, we discussed and suggested practical and political issues and implications in order to vitalize globalization of Korean SMEs in the conclusion.

Aromatic compounds are widely used in the chemical, food, polymer, cosmetic, and pharmaceutical industries and are produced by mainly chemical synthesis using benzene, toluene, and xylene or by plant extraction methods. Due to many rising threats, including the depletion of fossil fuels, global warming, the strengthening of international environmental regulations, and the excessive harvesting of plant resources, the microbial production of aromatic compounds using renewable biomass is regarded as a promising alternative. By integrating metabolic engineering with synthetic and systems biology, artificial biosynthetic pathways have been reconstituted from L-tryptophan biosynthetic pathway in relevant microorganisms, such as Escherichia coli and Corynebacterium glutamicum, enabling the production of a variety of value-added aromatic compounds, such as 5-hydroxytryptophan, serotonin, melatonin, 7-chloro-L-tryptophan, 7-bromo-L-tryptophan, indigo, indirubin, indole-3-acetic acid, violacein, and dexoyviolacein. In this review, we summarize the characteristics, usage, and biosynthetic pathways of these aromatic compounds and highlight the latest metabolic engineering strategies for the microbial production of aromatic compounds and suitable solution strategies to overcome problems in increasing production titers. It is expected that strain development based on systems metabolic engineering and the optimization of media and bioprocesses using renewable biomass will enable the development of commercially viable technologies for the microbial production of many aromatic compounds.

The Big Data, the element of the Fourth Industrial Revolution, is drawing attention as the 4th Industrial Revolution is mentioned in the 2016 World Economic Forum. Big Data is being used in various fields because it predicts the near future and can create new business. However, utilization and research in the field of packaging are lacking. Today packaging has been demanded marketing elements that effect on consumer choice. Big data is actively used in marketing. In the marketing field, big data can be used to analyze sales information and consumer reactions to produce meaningful results. Therefore, this study proposed a method of applying big data in the field of packaging focusing on marketing. In this study suggest that try to utilize the private data and community data to analyze interaction between consumers and products. Using social big data will enable to understand the preferred packaging and consumer perceptions and emotions in the same product line. It can also be used to analyze the effects of packaging among various components of the product. Packaging is one of the many components of the product. Therefore, it is not easy to understand the impact of a single packaging element. However, this study presents the possibility of using Big Data to analyze the perceptions and feelings of consumers about packaging.

In addition to recession, world shipping companies are undergoing restructuring due to excess of "World Container Cargo volume" per "World Containership capacity" (in TEU terms). This excess is attributed to the absence of standard index of calculating the "World Containership capacity" (in TEU terms) for "World Container Cargo volume." The purpose of this study is to develop indices and terms: "World Containership capacity (in TEU terms) Standards Index; WCSI" and "World Containership capacity (in TEU terms) Expected Index; WCEI." The comparison between "WCSI" and "WCEI" made in this study is presented below. WCSI (Average voyage 9.3) > WCEI Excess shipping (in TEU terms) WCSI (Average voyage 9.3) = WCEI Optimum shipping (in TEU terms) WCSI (Average voyage 9.3) < WCEI Short shipping (in TEU terms) WCSI=HRCI $1000{\pm}150$ Value approx. The study shows that it is possible to predict "optimal supply of the world's containership capacity" (in TEU terms), "excess or shortage of shipping" (in TEU terms), "order time of container-ship capacity building" (in TEU terms), "order quantity of containership capacity" (in TEU terms), and "stable of World Shipping Companies" by "WCSI" and "WCEI." The development of "WCSI" and "WCEI" aim to help overcome the crisis of recession by establishing effective business strategies for world shipping companies and their supporting companies.

The purposes of this paper were: 1) to identify the structural changes of the northeast Asia airport network caused by the pandemic of COVID-19 using social network analysis (SNA) and 2) to suggest proposals for improving airport competitiveness. In this respect, the entire international air routes in northeast Asia airport collected data of 4-10 March 2019 and 9-15 March 2020 through schedules analyzer database of OAG. We found that both the density and centrality have decreased since the spread of COVID-19. The government and airport authorities need active support such as a reduction of various fees and a moratorium on transportation rights to overcome the crisis in the air transport industry. When the COVID-19 situation calms down in the future, we hope that further research will be conducted to identify the structural changes in the SNA aspects through the vast data establishment in countries such as the EU and America.

High-grade limestone applied to various chemical industries is abundant within upper Pungchon formation in Taebaeksan basin, South Korea. Geophysical exploration is one of the most efficient methods to investigate subsurface geological structure in an extensive area. Since the geophysical exploration for the high-grade limestone has rarely been conducted in Korea, its appropriate strategy has not been set up yet. In this study, we focused on to suggest the reasonable strategy and accumulate geophysical databases which are essential for interpreting geophysical images by characterizing laboratory physical properties of in-situ rocks. Hence, rocks were obtained from drilled cores consisting of lower Hwajeol formation, Pungchon formation, and dykes in Jeongseon area, Gangwon province. Geophysical laboratory experiments and petrography of the rocks were conducted. Since susceptibility values of the rocks in Pungchon Formation were obviously lower than those of upper Hwajeol and dykes, it is considered that the lithological boundaries could be distinguished by magnetic survey. In addition, electrical properties of the rocks in middle Pungchon formation were relatively different compared with those of upper/lower Pungchon formations. Thus, induced polarization is shown to be able to detect the high-grade limestone in upper Pungchon formation.

Brown rice Makgeolli was brewed by using the Saccharomyces cerevisiae strain SRCM102596 under different fermentation conditions: temperatures at 20 and 25℃ and Nuruk ratios of 5, 10, and 15%. There were no significant differences in the pH and total acidity between samples. The alcohol content at the different nuruk ratios varied significantly by the days in the fermentation process. The major free sugars were maltose, glucose, and fructose, and they gradually reduced with fermentation. The major organic acids in the brown rice Makgeolli were oxalic acid, citric acid, malic acid, succinic acid, and acetic acid. The lactic acid content increased with the number of days in the fermentation process. Among the 24 different free amino acid contents identified, the total free amino acid content of, especially, threonine, serine, and alanine were high in the brown rice Makgeolli, at 20℃ and nuruk ratio of 10%.
