This study analyzed the globalization policy of ICT SMEs and ventures using cognitive map analysis and derived the priority to importance about action plans using AHP model, while the globalization paradigm has been rapidly changing in the ICT industry. Empirical results showed that policy tool variables should be needed to develop because policy goal variables are generally presented more than policy tool variables. In addition, this cognitive map could be characterized by a scarcity of feedback loops which means policy landscape for ICT SMEs and ventures' globalization is unilateral rather than cyclical to reach policy goal from policy tools. Another finding is that creative economy policy variable was not observed as policy tool variable but as policy goal variable. This means creative economy can be implemented through support for ICT SMEs and ventures' globalization. Finally, for detailed policy measures, installation of global start-up center, recruiting and utilization of global specialists, revitalization of ICT R&D international collaboration study, enlargement of global investment network, accompanied overseas advance of large enterprises and SMEs are presented in order in terms of the importance of policy priority.

The purpose of this study was twofold: 1) to analyze the impact factor of clothing and textile-related journals by utilizing the average number of cross-citation that evaluates the relative importance of an academic journal and 2) to provide a list of journals with higher impact factor by analyzing closeness and betweenness among individual journals through graph networks. To fulfill this, a total of 10 clothing and textile-related journals, which are accredited by National Research Foundation of Korea, were analyzed. For analysis of the average number of cross-citation, the targeted research papers were limited to those published between 2008 and 2011 and they were derived from the Korea Citation Index. The software used for network analysis was R ver. 2.15. The results of the study were as follow: First, 'The Korean Society of Knit Design' was indicated as the highest rate of self-citation, followed by 'Journal of the Korean Fashion & Costume Design Association.' Secondly, the average impact power of clothing & textile-related journals was relatively lower (0.681) compared to that (1.00) of 23 journals under the human ecology discipline. 'Korean Journal of Human Ecology' was found to have impact factor of 1.24, which was higher than the average impact factor of human ecology-related journals.

Summary. Most of American pop music, which are dominating the hegemony of the global pop music market, have been derived from the culture of African Americans, most of whom were slaves of European immigrants. The music of black slaves must be the one of the greatest undisputed achievements that have most influenced the American history. Indeed, All of the mainstream pop music works around the world, including those in America, are the descendants of the black music with the gene of the black people. We can say, therefore, the music born through the Afro-American culture has become the music that every person around the world enjoys in the present. Accordingly, K-Pop music culture, centered in idol group, is also based on the black music. This fact suggests that the K-Pop culture can be spread into people in different customs or traditions with little resistance. The success factor of Motown, at the very center of the black music, which integrated the whole global music, is not only their incredibly outstanding music works, but also the self-consciousness the musicians have that they are strongly reluctant to settle down to present reality. This shall lead to the necessity of self-reflection for the Korean music market, which are obsessed with present popularity and only taking advantage of teenager market, and for those engaged in music business in Korea, who are lack of the artistic value and the consciousness as artist.

This study examined the factors influencing foreign direct investment(FDI) in OECD countries where Korea is a target country. The differences in the cultural distances of host and home countries and the difference in the perceptions of corruption have been used to identify the factors affecting foreign direct investment. As a result of the study, it was found that there are differences in foreign direct investment according to cultural dimension and corruption perceptions index. Foreign direct investment may increase or decrease depending on the cultural tendency and the higher the perceptions of corruption, the more active the investment. The smaller the power distance between host country and home country in the factors affecting foreign direct investment, the larger the number of investments and the larger the size of individualism versus collectivism. Foreign direct investment increased when the investing country's corruption perceptions index was high. The results of this study confirm that cultural and corruption perceptions can affect trade transactions. Therefore, it is necessary to consider the cultural tendency and the cultural distance in the trade transaction by confirming that the degree of culture and corruption perceptions can affect the trade transaction. And that it can influence trade and economic growth by appropriately managing social variables such as public corruption.

Chatbot is emerging as an important interface window for business. This change is due to the continued development of chatbot-related research from NLP to NLU and NLG. However, the reality is that the methodological study of drawing domain knowledge and developing it into a user-friendly interactive interface is weak in the process of developing chatbot. In this paper, in order to present the process criteria of chatbot development, we applied it to the actual project based on the methodology presented in the previous paper and improved the development methodology. In conclusion, the productivity of the test phase, which is the most important step, was improved by 33.3%, and the number of iterations was reduced to 37.5%. Based on these results, the "3 Phase and 17 Tasks Development Methodology" was presented, which is expected to dramatically improve the trial and error of the chatbot development.

The advantages of Blockchain present the necessity of Blockchain in various fields. However, there are several disadvantages to Blockchain. Among them, the uncle block problem is one of the problems that can greatly hinder the value and utilization of Blockchain. Although the value of Blockchain may be degraded by the uncle block problem, previous studies did not pay much attention to research on uncle block. Therefore, the purpose of this study attempts to predict the occurrence of uncle block in order to predict and prepare for the uncle block problem of Blockchain. This study verifies the validity of introducing new attributes and ensemble analysis techniques for accurate prediction of uncle block occurrence. As a research method, voting, bagging, and stacking ensemble analysis techniques were employed for Ethereum's uncle block where the uncle block problem actually occurs. We used Blockchain information of Ethereum and Bitcoin as analysis data. As a result of the study, we found that the best prediction result was presented when voting and stacking ensemble techniques were applied using only Ethereum Blockchain information. The result of this study contributes to more accurately predict the occurrence of uncle block and prepare for the uncle block problem of Blockchain.

Currently, despite the quantitative growth of domestic journal, objective and metric criterion to evaluate the contents and quality of those journals is inadequate. As a result, depending on a foreign citation index like SCI to evaluate the research result is causing some problems such as, thesis of an excellent standard being presented and published in foreign countries, thus, neglecting journals written in Korean. Hereat, the Korea Citation Index(KCI) is constructing a database of the journals published by academic associations; scientific paper information, articles information, and bibliographic, analyzing the quoting relation. Consequently, KCI is providing the basic information and the corresponding quoting relations of journals and papers on its webpage. This study compares the impact level of domestic accounting related journals by KCI and analyzes the network among journals using the cross-citation frequency from a social network analysis point of view. As a result, Accounting-related journals are now more desirable than the location in order to have a variety of interdisciplinary research needs to be encouraged. Through this exchange of other disciplines and actively made, which is the phase of apparent accounting-related journals expect to be greatly enhanced looks.

In this paper, we analyze accident factors that occur in the unloading of steel cargoes and try to derive priority of importance among factors. The Fuzzy-AHP, which enables hierarchical analysis through pairwise comparison of factors, is used to derive priorities of safety factors to consider when unloading steel cargo. In the top factor analysis results, weights were ranked in order of human factors, safety education, equipment and facilities, and business environment. The purpose of this paper is to contribute to the improvement of the safety consciousness of the field workers and enterprises and to reduce the incidence of accidents in the unloading and unloading operations by deriving the relative importance between the factors. In the future, it is necessary to study the cargoes of other disasters such as container cargo as well as steel cargo.
