  • The present paper is a part of the studies on the larvae of subfamily Alticinae in North America. Eight species were described and illustrated belonging to genus Altica in the subfamily Alticinae: Altica ambiens alni, A. bimarginata, A. brisleyi, A. litigata, A. potentillae, A. sylvia, A. torquoto and A. ulmi. It is the first to deal the larvae taxonomically in North America. Their key and taxonomic remarks are also given.

  • Although there is progress in developing green sectors in North America and East Asia, the key challenge facing the expansion of economy-wide green innovation and structural change in these regions is the absence of relevant policy follow-up to the green stimulus enacted during the Great Recession. The boost to green sectors provided by such measures is waning quickly, given that much of the green stimulus focused on energy efficiency. The biggest obstacles to sustaining green growth in North America and East Asiaare major market disincentives, especially the under-pricing of fossil fuels and market failures that inhibit green innovation. A three-part strategy to overcome these obstacles would involve: first, removing fossil fuel subsidies; second, employing market-based instruments to further reduce the social costs of fossil fuel use; and third, allocating any resulting revenue to public support for green innovation and investments. Such a strategy would ensure that green growth is not about promoting niche green sectors but instigating economy-wide innovation and structural transformation in North America and East Asia.

  • An empirical predictive relationship correlating bracketed duration to earthquake magnitude, site-to-source distance, and local site conditions (i.e. rock vs. stiff soil) for stable continental regions of North America is presented herein. The correlation was developed from data from 620 horizontal motions for central and eastern North America (CENA), consisting of 28 recorded motions and 592 scaled motions. The bracketed duration data was comprised of nonzero and zero durations. The non-linear mixed-effects regression technique was used to fit a predictive model to the nonzero duration data. To account for the zero duration data, logistic regression was conducted to model the probability of zero duration occurrences. Then, the probability models were applied as weighting functions to the NLME regression results. Comparing the bracketed durations for CENA motions with those from active shallow crustal regions (e.g. western North America: WNA), the motions in CENA have longer bracketed durations than those in the WNA. Especially for larger magnitudes at far distances, the bracketed durations in CENA tend to be significantly longer than those in WNA.

  • We have been examining the issue of healthcare workers' exposure to antineoplastic drugs for nearly a decade and have observed that there appears to be more publications on the subject matter originating from Europe than from North America. The concern is that findings from Europe may not be generalizable to North America because of differences in handling practices, regulatory requirements, and training. Our objective was to perform a literature review to confirm our observation and, in turn, identify gaps in knowledge that warrants addressing in North America. Using select keywords, we searched for publications in PubMed and Web of Science. All papers were initially classified according to the originating continent and then categorized into one or more subject categories (analytical methods, biological monitoring, occupational exposure, surface contamination, and probability of risk/exposure). Our review identified 16 papers originating from North America and 55 papers from Europe with surface contamination being the subject matter most often studied overall. Based on our results, we are of the opinion that North American researchers need to further conduct dermal and/or urinary drug contamination studies as well as assess the exposure risk faced by healthcare workers who handle antineoplastic drugs. Trends in exposure levels should also be explored.

  • As Korean online game market is saturated, Korean online game companies are trying to push into North American market. In order to succeed in foreign markets, understanding of user characteristics in that country is most important. In this study, investigation on user characteristics has been performed using user DB from A online game and B online game. They are currently in service by M company in America. Connection time, payment, and royalty are analyzed as a results. Based on the analysis, several advance strategies into North America are suggested. This results could be very useful for Korean MMORPG company to try to push into North America.

  • The purpose of this paper is to examine the growth trends and volatility of exports in Asia, North America, Europe, Central and South America, Middle East and Africa since 2010. And analyze the correlation and model analysis to find out future directions of development. As a result of the analysis, it showed high export share in Asia, North America, Europe, Central and South America, Middle East and Africa. Asia, North America, Europe showed a relatively high rate of increase in exports and the month-on-month rate of change was stable in Asia and North America. In order to increase our exports through this research, we should pay much attention to export improvement to Asia, North America and Europe. Especially, Asia's exports account for more than 50%, so it seems necessary to plan export enhancement to China, Japan, Vietnam, Hong Kong, Taiwan and India. Although the proportion of exports is not large yet, much attention needs to be paid to new markets in Central and South America, the Middle East and Africa. And I look forward to systematic progress in export promotion.

  • Two new coexisting sepcies of the genus Bathynella of the Bathynellidae is described from North America. B. germanitas n. sp. is easily recognized by the basidorsal existence of cylindrical protrusion with a seta on endopod of uropod, whereas B. fraterna n. sp. is characterized by by the setal nature of exopod of thoracopods II-Vll.

  • The purpose of this study is to examine the trends of import and export of Korea by each continent and to find ways to increase export to Korea in the future. Each continent selected Asia, Europe, North America, Central and South America, and the Middle East. The analysis period was 220 months from January 2000 to April 2018, and data were collected from the KCS. Regression analysis showed that the coefficient was higher in Asia, Europe, North America, Middle East and Latin America. The markets of each continent moved independently of each other and were statistically significant at t statistic and p-value(${\leq}0.01$). As a result of this study, Asia and North America have been major export markets in Korea. Europe, the Middle East and Central and South America are emerging as new markets in Korea. In order to increase Korea's exports in the future, there is a need for continued interest in Asian markets including China & Southeast Asia.

  • China and North America have been South Korea's biggest trading partner long time. As the volume of trade has been increasing, the disputes between Korean companies and Chinese Companies and between Korean companies and North American Companies have been increasing. If these disputes are settled by Arbitration, the parties appoint arbitrators who are empowered to proceed the arbitration procedure and have a power to render an arbitral award. Accordingly, it is very important for the parties to select who is an arbitrators in Arbitration. But if the parties doubt their arbitrator(s)'s fairness and independency, they can discharge them in accordance to law and arbitration institute's rules. In comparison with arbitrator system for way of selection and discharge among Korea, China and North America, some differences are found. First, if parties fail to appoint co-arbitrators or the presiding arbitrator by a mutual agreement, the court has the right to appoint them or him in Korea and North America whereas the Chairman of CIETAC choose him in China. Second, the authority to decide whether arbitrator is discharged owing to his fairness and independency, depends on arbitration institute and court in Korea and North American whereas it depends on the Chairman of CIETAC only.
