Damyang riverine wetland was designated as a wetland protected area in 2004; that is located in the Yeongsan river mainstream. Total 30 phytosociological releves at field studies were classified with 22 vegetation types including of 101 species (unidentified 1 species). Legends of actual vegetation map were separated by 6 types; riparian forest, substitute vegetation, synanthropic vegetation, wet meadow vegetation, open water, an area of wetland vegetation is about 35 % ($386,841.86m^2$). Results of this study area as follows. The plant society of Damyang riverine wetland was conjectured that it was formed by rapidly water environment change with installed weir on the upstream of protected area and operating of Damyang dam on top of the basin. Until recently, the terrace land on the river was used to cultivate, but that would be formed fallow vegetation scenery on riverfront caused by no cultivation after designated protected area. Paspalum distichum var. indutum community designated as invasive alien plant by Korea Ministry of Environment was widely developed and Myriophyllum spicatumunrecorded in the country as newly alien species was discovered in the study zone. The plants as lapped over developing environment for Leersia japonica must be occupied habitat of native plant species having similar niche. The various plant society in Damyang riverine wetland should be developed because of environmental changes, disturbances and damages of stream.

The purpose of this study is to examine the narrative correlation of nonverbal signs found in Charade. Charade, by using nonverbal signs, provides information about the character's psychological change, his or her relationship with others, and the places where they stay. The study of Charade, then, has to be approached considering not only the transmission of messages through nonverbal signs but also its signification. This study has analyzed the narrative and formation process of the subject that triggers the subject's activity by taking narrative semiotics to the film Carol (2015). As the status of women is represented by the mise-en-$sc{\grave{e}}ne$ at this time, this study aims to examine such a fact through Charade, which belongs to the realm of mise-en-$sc{\grave{e}}ne$. In this study, nonverbal signs that are used in Charade are drawn based on the nonverbal communication theory. The result of analyzing the texts showed that the use of interior decoration was outstanding in the process of expressing the status of female subjects. The use of gaze was noticeable in the process of expressing the acquisition of female subjects' power. Besides, it should be noted that the use of nonverbal signs such as accessories, territoriality, or gesture, was worthy of attention. It was confirmed that such nonverbal signs play an important role in the formation of subjects and configuration of narrative transformation.

Ethnic entrepreneurship, an important means by which immigrants improve economic status, is widely believed to be facilitated by their residential concentration, i.e. ethnic enclaves. However, the recent immigrants' residential dispersion and re-clustering in some selected well-to-do suburbs portend changes in the role of ethnic enclave as a nest of immigrant entrepreneurship. This paper investigates the impacts of the residential dispersal on ethnic entrepreneurship with a case study of Korean small businessmen in Chicago, Illinois PMSA. The research utilizes the Public Use Microdata Sample (PUMS) to know the overall changes in Korean entrepreneurship through 1990s and conducts a survey to understand reactions and surviving strategies of Korean enclave businessmen to the residential shifts. Relevant to those analyses is the enclave-economy hypothesis which argues benefit from spatial clustering of co-ethnic entrepreneurs by yielding more business opportunities and higher returns.

Unlike existing other industries, the knowledge-based industry has the potential to grow increasingly with factor input unlimited. Importance of investigating knowledge and information evaluation cannot be overemphasized to promote economic development in that knowledge and information is accepted as an engine of new economy. We attempt to define the scope and value of knowledge and information and develop the knowledge and information value model. The results help policy-makers to manage and evaluate the knowledge and information with useful and responsible information.

Conservation of Arctic Flora and Fauna (CAFF) is the biodiversity working group of the Arctic Council. CAFF conducts Monitoring, Assessment, Policy, and expert group activities to preserve Arctic biodiversity and ensure the sustainability of biological resources and communicates the results to governments and indigenous peoples. The main tasks of CAFF consist of monitoring (Circumpolar Biodiversity Monitoring Program), assessment (Arctic Biodiversity Assessment) and strategic projects(Arctic Migratory Bird Initiative, AMBI). Korea has been directly participating in the AMBI since 2015 after acquiring observer status of the Arctic Council in 2013. The AMBI aims to preserve habitats on migration routes used by breeding birds in the Arctic and prevent illegal hunting. Thus, observer countries on migratory routes are directly participating in the project. When selecting priorities for participation in Arctic cooperation projects by 2030, Korea should consider continuing participation in AMBI and participating in the "CAFF Youth Program" in connection with the Arctic Academy program operated by Korea's public institutes.

Social work credentialing systems, which is broadly defined as encompassing licensing, certification, and registration, play an important role in the development of professionalism. The U.S., Japan, and South Korea have developed their own social work credentialing systems, in order to enhance social work professionalism in their own contexts. In this paper, using case-oriented strategy(Ragin, 1987, 1994), we discuss the social work credentialing systems of the U.S., Japan, and South Korea, with particular attentions to the issues related to eligibility, exclusive status as a profession, and regulation on social work education. We also provide recommendations for enhancing social work professionalism in South Korea through comparing social work credentialing systems of Japan and the U.S.

Despite the recent rapid advancement of science and technology, we have been experiencing the decline in productivity since the 2000s. This study aims to investigate the decline at both industry and firm levels, by looking at the emergence and growth of large firms such as Amazon, Alphabet, and Apple and M&A trends. Following the results of previous studies, our results show that productivity at industry level has decreased since the 2000s. Particularly, in the period after 2011, the deterioration of allocative efficiency due to the large firms and the decline in the growth rate of surviving firms in the industry with low ratio of large firms contributed to the productivity decline. On the other hand, our analysis at firm level demonstrates that the productivity of firms that acquired IT firms improved over the entire period. While M&As have a positive impact on productivity, M&As with a demand-side motive such as market penetration and expansion of channels have a relatively larger impact than the ones for production or operation efficiency. Our results also suggest that the higher the proportion of large firms in a specific industry, the lower the productivity of individual firms in the same industry. Overall, given that the industry's structural changes for digital transformation tends to strengthen the growth of large firms, our findings have significant implications by empirically identifying the relationships of the emergence of large firms, the acquisition of IT/Non-IT firms, and motivations for M&As to firm/industry productivity.

The study was conducted to find out the relationship between land cost and financial yield earned by the plantations of Pinus koraiensis, Pinus densiflora and Cryptomeria japonica, and to investigate possible land investment for the given rates of return. The result of the study could be summarized as follows: 1. In the case of Pinus koraiensis plantation on site index 12, the finnancial yield was 6.4 percent when the land cost was 0.5 million Won per hectare, but the yield was reduced to 2.1 percent when the cost was 2.5 million Won. It would be therefore necessary for inducing plantation investment to raise financial yield by control of forest land price. 2. The financial yield on land of zero expectation value, in other words, internal rate of return of land investment was estimated at 10 percent. If the opportunity cost of forest land is higher than this, the economic plantation is not visible even though the land is free. 3. With the expected financial yield of 3 percent, the possible land investment of poor sites was estimated at 1.24, 0.28 and 0.80 million Won per hectare for the plantation of Pinus koraiensis, Pinus densiflora and Cryptomeria japonica, respectively. In any case, however, land cost could not be over 3 million Won per hectare. 4. The rate earned from forest land investment was generally less than 10 percent. Therefore, the annual interest rate in forestry could not be higher than this, and hopeful rate is not exceeding 6 percent.

This paper explores the inter-ethnic conflicts between Blocks and Hispanics focusing on the emergent Hispanic ethnictity that reveals situational character in the US contexts. In the US census categories, major groups are indetified by race and ethnicity in which the Hispanic orgin is a category based on their common language while diverse in nationality. The census defined Hispanic category extends conveniently to acquiesce Affirmative Action and other government resource distribution. Internally, Hispanics have established numerous organizations to coalesce and assure their interests. The achieved dual language program and jurisdictional revision to represent language minority work as leverages to their cohesiveness. Under diminishing public resources and welfare payment, it is more difficult sharing burdens than benefits between minority groups. Block are not comfortable with the benefits Hispanics receive form the civil rights achievement without having had to struggle for it. The ethnic conflicts of the have-nots have become a new ethnic phenomenon attributable to the emergent Hispanic ethnicity.

The world-wide principal criteria of aircraft operations is ICAO Annex 6. Operations of Aircraft. Among ICAO Annex 6, Part I is for International Commercial Air Transport - Aeroplanes and it assumes major part of civil aviation. ICAO has been providing Contracting States with SARPs(Standards and Recommended Practices) and monitor each State's reflection degree into their domestic air law, so-called USOAP(Universal Safety Oversight Audit Program). Current ICAO USOAP is Snap-shot method, but it will be changed to USOAP-CMA method from the year of 2013. ICAO USOAP results have overall effects on national aviation industry such as routes, insurance, airlines cooperation and so forth. Low grades of results attract international attention and that leads to flag carrier's operation stoppage, route restriction, airlines cooperation restriction, insurance increase directly or indirectly. Thus it is important to get excellent grades in ICAO USOAP and to maintain confidence. Our government ranked top to get 98.89 grades in 2008 ICAO USOAP but after 2008 the revised provisions have not been reflected sufficiently into our air law. So I would like to grip reflection ratio of ICAO Annex 6 Part I into our domestic air law by using the most updated revised edition on this paper. Together I would like to suggest alternatives for the non-reflected and partially reflected.
