We apply the GSADF bubble test and its date-stamping method for the daily number of new COVID-19 cases. The test indicates statistically significant explosive expansions of the number of new cases whose periods of panic explosion are identified by the date-stamping method of the bubble test. The date-stamping analysis reveals that as of June 30 2020, the number of daily COVID-19 new cases are still explosively increasing for India; however, they stop explosively increasing (or are under control) for USA, Brazil, Russia, Spain, Turkey, China, and South Korea. It also reveals that South Korea has two disjoint periods of explosion: a stable period follows after the first explosion of 2020.02.20-2020.03.06, and then the second explosion occurs 2020.05.27-2020.06.01 with a stable period that continues up to 2020.06.30.

Being a staple food for more than half of the population of the world and South Korea, rice is an important crop. For the past 20 years, global paddy rice cultivation area and production have shown an annual growth of 0.46% and 1.61%, respectively. Global rice consumption for food and processing has increased by 1.37% and 3.68%, respectively. Due to the main reason for such increasing human population, it is expected that from 439 million tons in 2010, additional 116 million tons will be needed in 2035. Global rice imports and exports have doubled in the last 20 years. However, in spite of such increment, global rice exports in 2013 were 8.4% of the total production. It is thought that rice protection policies in the producing countries are the main reason for such small scale of rice trading. In the past 5 years, India recorded the largest growth rate in rice exports (51.4%), whereas China showed the largest growth rate in imports (61.0%). For global utilization of milled rice during the same period, approximately 79.4% was used as food, 7.2% as animal feeds, and 1.4% for processing. Regionally, Asia has shown a similar pattern to the global rice usage, whereas utilization for processing in America, for food in Africa, and for animal feed in Europe was relatively higher than the global rice usage. Korea's cultivation area and production since the last 5 years, are 0.5% and 0.8% of those of the world, respectively. Its annual rice export is approximately 3,000 tons, which is 0.01% of the global rice export. Korea's rice utilization is high for food and low for feed and for processing relative to global rice utilization. Therefore, a review must be conducted to increase Korea's utilization of rice for processing and for feed production.

As a part of the R&D efforts for the hypersonic vehicles, various flight test programs has been carried out using small launch vehicles or sounding rockets. Australian HyShot program is a representative case of the flight test program for scramjet engines carried by international collaborations. A number of hypersonic flight test programs has followed in a similar way. In USA, Falcon HTV-2 was carried by DARPA, X-51A by AFRL and HyFly by ONR. HyCAUSE and HIFiRE were carried in collaboration with Australia. In France, LEA program is on the way similarly to X-51A. Russia, China and India seems like carrying out flight test programs for the development of hypersonic defense system. The goals, technical elements, the status and the relation between the programs were summarized in this paper as a reference for the similar program of the country in the future.

An Asian Ethnic Look is based on its own values of traditional costumes and the fashion accessories that are influenced by its own genre within their own culture. In this thesis, it contemplates the study of visual values and the traditional influences of the Modern Western Designers and Asian Designers' definitions and the considerations of an Ethnic look in the countries like Middle East, India, Korea, China and Japan. The standard procedure to understand their Visual and Aesthetic values is acknowledgement of body. From that foundation, an Asian Ethnic Look and its Visual and Aesthetic Values were researched through out the Middle East Asian Look, Indian Look, Korean Look, Chinese Look and Japanese Look which effective after 1990's. The studies are further researched to the comparisons and interpretations of the Western Designers and the Asian Designers, and the definitions of an Asian Ethnic Look and its Visual and Aesthetic Values in between those. According to each country's religious attitudes, a beauty of concealment and a beauty of negative space appeal which emphasize an ethics on humanity and non-materialistic attitudes. It takes meanings of a phenomenon of nature's worship, Yin-Yang five elements of principles, oneness of body-mind and oneness of universe-mankind. Following the studies of Visual and Aesthetic Values of an Asian Ethnic Look, in 1990's Western Designers' interpretations were prominent use of the Asian Traditional Motif3. However, the interpretations of the Asian Designers were based on their own traditional ethics and they minimized decorative elements but enhanced naturalism, feminism, calm and sober designs compare to the past. The Asian Designers' interpretations of their visual values were based on their Asian mentality, beauty and its straightforward genuine perspective and respects of their own culture.

A new medium for studies of diversity among populations of $A_1\;and\;A_2$ mating types of Phytophthora infestans has been evolved. The rye A agar and V-8 juice agar media on which P. infestans grows well have been amended with rhizome powder of Cyperus rotundus. A total of 259 isolates of $A_1\;and\;A_2$ mating types representing Japan, Korea, India, Taiwan, Indonesia, Thailand, China, Nepal, U.K and Medico were screened for their growth response on these two media. Most of the A1 isolates did not grow well on them except Thailand while growth of $A_2$ mating types differed as some grew on it whereas others did not. It is quite likely that the populations of $A_2$ mating types that did not grow well on rhizome-amended medium are of different clonal lineage. This suggests that this medium can be used for the study of diversification among the isolates of the same or both the mating types as well as to detect the newly introduced genetically different isolates of P. infestans in a locality where it was not reported earlier.

This study investigates the potential for multi-cultural youths, given their innate bilingual and dual culture, to be trained as the competent ODA professionals. For the purpose of collecting information, we organized two different kinds of FGI in 2015. The first FGI was conducted with a group of 10 expert participants from August 17 to September 25. The second FGI was conducted four times, from October 5 to October 23, with 13 adolescents from multi-cultural families from Russia, Mongolia, Vietnam, India, Indonesia, Japan, and China. The semi-structured interview items were passed through a formal review process of the Institutional Ethics Committee. Furthermore, with the participants' pre-consent to recording, all recorded data were categorized through the transcription process. The results are as follows. While the potential for nourishing bilingual and dual cultural capabilities are high for the adolescent children of multi-cultural families, the expert group also emphasized the negative aspects of these capabilities being suppressed due to the relatively oppressed family environment. The expert group therefore suggests the following: building parent awareness of ODA human resources, developing an educational career transition roadmap, and providing institutional incentives for ODA. In addition, to some extent, the researchers were able to detect some positive self-esteem among the adolescent children of multi-cultural families as a result of the bilingual and dual cultural competencies required to be ODA personnel. In sum, the research provides insight into the need for national social support for the adolescent children of multi-cultural families, so that their strengths are not extinguished, in order that they might grow up as competent ODA personnel.

In 2019, the U.S. Department of Defense and the U.S. Department of State issued two reports to announce their plan to fulfill "free and open Indo-Pacific". Two reports commonly insisted on the support and participation from allies and partners to maintain security and stability in the Indo-Pacific. In response to this, neighboring states in the Indo-Pacific, including Japan, Australia, India, ASEAN, and Taiwan have different perspectives and stances based on their national interests. South Korea, too, has not clearly announced its position because they need to consider the alliance between the U.S. and South Korea as well as relationships between South Korea and China. This report focuses on the stances of neighboring states to the Indo-Pacific strategy and expected pros and cons of the participation of the strategy. In addition, when considering the name of strategy, the Indo-Pacific, naval power will be a main instrument to implement the strategy. Thus, this study also investigates the role of naval power in the Indo-Pacific strategy.

For several decades, Asian nations such as Korea, Japan and China have been leading the shipbuilding industry since the decline in Europe and America. However, several developing countries such as India, Brazil, etc. are going to make an entrance into the shipbuilding industry. These developing countries are finding technical partners or information providers because they are in situation of little experiences and technologies. Now, the shipbuilding engineering companies of shipbuilding advanced countries are getting a chance of engineering business against those developing countries. The starting point of this business model is green field project for the construction of new shipyard. This business model is started with a design of the shipyard layout. For the conducting of the shipyard layout design, four kinds of engineering parts are required. Those are civil engineering, building engineering, utility engineering and production layout engineering. Among these parts, production layout engineering is most important because its result is the foundation of the other engineering parts and it determines the shipyard capacity during the shipyard operation lifecycle. Previous researches about the shipyard layout design are out of the range from the business requirements because most research cases are in the tower of ivory, which means that there are little consideration of real ship and shipbuilding operation. In this paper, a shipyard layout design for preliminary phase is conducted for the target of newly planned shipyard at Venezuela of South America with an integrated method that is capable of dealing with actual master data from the shipyard. The layout design method of this paper is differentiated from the previous researches in that the actual product data from the target ship and the actual shipbuilding operation data are used for the required area estimation.

With the globalisation of the world's economies and the increasing role of multinational corporations in the generation of knowledge, global research and development (R&D) activities in emerging countries are following a new trend. This paper describes case studies of two large companies and discussion of the motives (demand vs. supply) and tasks (demand-driven vs. supply-driven) of R&D activities outside their home country. This work is based on an analysis of four overseas R&D units of two Korean ICT companies - here, ICT refers to goods and services in the information technology and communication technology fields - in India and China. The research findings are as follows: (1) The overseas R&D activities of Korean ICT enterprises in emerging countries may be driven by a combination of demand and supply factors of host countries; and (2) Korean overseas R&D centres in emerging countries may need to carry out both demand- and supply-driven tasks in view of the overlap between demand and supply factors of the host countries. Based on the results of this research, the following policy implications can be drawn for encouraging more effective overseas R&D activities of Korean enterprises in emerging countries. First, the government needs to expand the support systems so that enterprises can manage local R&D centres more effectively and actively use the variety of local support systems and useful information. Second, the government needs to expand the support systems so that the overseas R&D centres of Korean enterprises revitalise collaborations with locally excellent universities and research institutions.

Phyllostachys consists of high and fast growing trees and is a genus in the family Gramineae. The genus has many species in Asia, with main distribution being in India and China. One of the most popular sequences for phylogenetic inference at the generic and infrageneric levels in plants is the internal transcribed spacer (ITS) region of the 18S-5.8S-26S nuclear ribosomal cistron. We evaluated four taxa with the ITS region to estimate phenotypic relationships within the genus Phyllostachys in Korea. Alignment of the DNA sequences required the addition of numerous gaps. Sequence variation within the Phyllostachys was mostly due to natural selection, although several indels and inserts were found. Within the genus Phyllostachys, P. nigra and P. nigra var. henonis were the relatives in the three phylogenetic analyses (MP, ML, and NJ). However, some external nodes were poorly supported. Morphological traits and simple repeats (ISSR) represented the result of a relationship similar to the that of ITS sequences in the genus Phyllostachys. This suggests that ITS sequences are very informative for identification of these taxa.
