Recently, International commerce has continuously expanded with the development of logistics technology. However, the cost of international logistics is rising rapidly. The Korea International Trade Association (2021) proposes that the use of international commercial terms in Incoterms® could be an effective way against logistics costs. The purpose of this study is to verify the effect on the flexible operation of international commercial terms. For the detection of variables and data collection for empirical analysis based on previous studies and in-depth interviews. The questionnaires were distributed after pilot-study to a random sample of companies based on the list of members such as the Korea International Trade Association, the Korea Trade-Investment Promotion Agency, and the Global Small and Medium Business Association. A total of 800 questionnaires were distributed, and 166 were used for empirical analysis. The results of this study are as follows. First, mutual cooperation and Flexibly using of international commercial terms has a positive (+) effect on logistics efficiency. This is in line with the study of Yang (2021) and Stojanović et al. (2021) that logistics by using international commercial terms will increase the efficiency of logistics. Second, use of international commercial terms based on mutual understanding mediates the relationship between the logistics environment of the other country and the logistics efficiency. As in the study of Vidrova (2020), it is important to operate on international commercial terms mutually.

Recently, labor unions' active participation in social issues is drawing people's attention as their concerns are expanding from the conventional wage raise and employment to others such as the environment and poverty eradication. This derives from the notion that a trade union with bargaining power is also an economic agent responsible and able to take a positive role in social issues. This paper explains through a micro economic analysis model that labor union movements can also contribute to social issues such as the global environment. Based on the international oligopoly trade theory, the study analyzes the principal-agent model whereby firms and labor unions pursue their strategic choices based on their interest and influence the implementation of regulatory policies on pollution emission. The analysis confirmed that labor unions' bargaining power and international cooperation are influential in alleviating global pollution emission and in improving social welfare. This conclusion could be presented as a basis for arguing for and requesting the participation and cooperation of labor unions to solve environmental problems discussed at WILL 2006.

The ESS load test device (ELTD) can store and exchange electrical energy during the load test of an emergency generator. On the other hand, it is difficult to commercialize ELTDs based on Li-ion batteries because of the high initial cost, which is higher than a load bank test. If the trade of electrical energy stored in ELTD during the test of an emergency generator is considered, it may be possible to commercialize the ELTD. Therefore, this paper proposes an economic model of ELTD composed of the costs and benefits by considering electrical energy trade to perform accurately economic evaluations of an ELTD. From the simulation results of the economic evaluations of an ELTD and the load bank method, it was found that the commercialization of ELTD is possible when the trade in electrical energy in ELTDs is considered.

Modern file systems have journaling mechanism to maintain their stored state consistently even under unexpected system crashes or disasters. However, the journaling makes I/O throughput lower. This performance degradation comes from the ordering mechanism between the data buffer and metadata buffer and two-staged buffer writing. Especially, if the data buffer and metadata buffer are journalled at the same time, then it incurs significant performance degradation due to the two-staged writing. That shows the trade-off relation-ship between I/O performance and system reliability. In this paper, we propose RFJ: a reliable and fast jour-naling mechanism to deal with this trade-off relationship. We propose an ordering enforced writeback journaling mode and selective journaling mechanism. The Ordering enforced writeback journaling mode achieves low I/O latency and the selective journaling mechanism achieves high reliability. The experimental result shows that the performance of RFJ is almost 5x faster than the journal mode of Ext3 file system but it still supports the same reliability with the journal mode.

For the past years, there had been some environmental cooperation among East Asian countries to reduce air pollution emissions from China. However, the progress of cooperation has been under developed because of lacking financial support, poor design of planning, and weak economic incentives for the industries. In this paper, some practical approaches have been suggested. First, electric trade to make Asian Grid among countries will be good alternatives for the fossil fuel, such as coal, for China. Secondly, natural gas pipeline from West China to Siberian pipeline would change the whole energy mix in this area around 2010, Therefore, it is very promising area for the energy industries to involve in gas project and get rid of many institutional barriers from China. Lastly, environmental industry is growing fast in East Asian. In China, waste treatment and management, air pollution control, and water quality management are some promising areas for the future. Hence it is desirable for Korea, Japan and China to make a eco-fund or company to boost up environmental technology as well as environmental market size.

Due to rapid growth of economy in the world, which results into shipping goods flow one place to another in large volumes, the competition becoming more intense among ports. Shanghai port and Ningbo-Zhoushan port are the two most important ports in the Yangtze River Delta and have the same economic hinterland, inevitably there is a heated competition between the two ports. This paper using the approach of SWOT to analyze the issue of competition and cooperation between the two ports, and then makes an analysis of their Co-opetition strategies by employing the analyzing methods based on the Game theory. Finally, it puts forward some strategies to enhance the cooperation between the two ports.

The objective of this study is to improve export performance using e-Trade marketing systems. The use of e-Trade has been increasing but there is some controversy about the performance of e-Trade marketing for Small-to-Medium enterprises (SME). The research construct for determining the export performance is suggested and five factors are introduced in this paper such as: B2B relationship and cooperation, product complexity, online fitness, level of internationalization, and use of e-Trade marketing. Sample data were collected from the companies who are familiar with the e-Trade systems. The result shows that the use of e-Trade marketing mostly contributes to the increase of export performance. The regression and cluster analysis shows that both variables of e-Trade marketing and on-line fitness are significant to high export performance group. The implication for SMEs is that the use of e-Trade marketing methods could contribute to the increase of export performance and more analytical works need to be made for future study.

Cooperative diversity protocols have attracted a great deal of attention since they are thought to be capable of providing diversity multiplexing tradeoff among single antenna wireless devices. In the high signal-to-noise ratio (SNR) region, cooperation is rarely required; hence, the spectral efficiency of the cooperative protocol can be improved by applying a proper cooperation selection technique. In this paper, we present a simple "cooperation selection" technique based on instantaneous channel measurement to improve the spectral efficiency of cooperative protocols. We show that the same instantaneous channel measurement can also be used for relay selection. In this paper two protocols are proposed-proactive and reactive; the selection of one of these protocols depends on whether the decision of cooperation selection is made before or after the transmission of the source. These protocols can successfully select cooperation along with the best relay from a set of available M relays. If the instantaneous source-to-destination channel is strong enough to support the system requirements, then the source simply transmits to the destination as a noncooperative direct transmission; otherwise, a cooperative transmission with the help of the selected best relay is chosen by the system. Analysis and simulation results show that these protocols can achieve higher order diversity with improved spectral efficiency, i.e., a higher diversity-multiplexing tradeoff in a slow-fading environment.

Large tundra of the Russian Empire, has rich resources and science and technology, and a huge domestic market potential is rapidly changing. Based on the abundant energy resources such as oil, gas, and minerals, as foreign trade is active, the huge capital is moving. And commitment the active SOC by improving laws and regulations and changes in the structure of the Russian economy. One of them pushed the WTO since 1993, 19 years to see fruition join the WTO (World Trade Organization). As the official entry into force August 22, Russia, July 10, 2012, Congress passed the treaty after joining the WTO and of the 156th WTO member countries, was officially join. As the WTO, Russia has the world's 11th-largest economy in the steel tariffs from 30% to 15% are exported to Russia, South Korea Car TV parts from 10% to 0%, reduced from 20% to 5% Korean export companies to export to Russia, etc., is expected to become the new land of opportunity. Russia hopes the changes improve the investment environment, the service industry, manufacturing revitalization the macroeconomic sectors of the economy through the WTO, and forecast, but the consumption increased revenue due to tariff cuts, falling import prices and the real economy, and weak manufacturing base. On the one hand, the perspective of concern. In conclusion, Russia joining the WTO, and the feed to improve the fairness and transparency of the market opening, the Russian advance in Korean companies be facilitated and strong complementary cooperation, especially in manufacturing is expected. In this paper, after Russia joining the WTO, trade liberalization, and ready for a new era of economic cooperation between Korea and Russia, at the point of expanding openness to propose strategies to analyze the problems of Korean companies during the Russian advance.

The purpose of this study was to understand and improve the clothing habits and the apparel industry of North Korea in preparation for the reunification of South and North Korea. For this study, literary data, reports, periodicals, interviews and internet data of the two Koreas were reviewed. North Korean clothing habits used to be monotonous and uniform but nowadays people's clothes have become somewhat brighter in color and more diverse in design than before. In particular, liberal and individual dressing habits appeared among the privileged classes. When taking part in national events, women have to wear the traditional Korean costume, Hanbok, while men wear business suits for formal wear. In general, men don't wear Hanbok. Students have to be in uniforms but blue jeans, T-shirts with English logos were popular among them reflecting their sensitivity and openness towards western cultures. The brides usually wear pink Hanboks and the bridegrooms wear black business suits for their wedding. North Koreans also wear Hanbok on national holidays like South Koreans. Clothing is the most important item in the trade of process commission between North and South Korea. Trading items are mid to low end men's clothing for the most part due to less emphasis on fashion in the North. The processing is indirect trade and composed of sample making and contracting, sending out materials and production, carrying in goods and setting accounts. To activate South-North trade, establishment of infrastructure, stabilization of shipping, reducing high costs of distribution, building direct communication system by setting up office in a neutral zone and simplifying procedures in applying for the South and North Korea Economic Cooperation Fund. On the other hand, clothing and textiles education is carried on at art colleges, light industries colleges and commercial colleges in Pyongyang. Clothing institutes which study Hanbok and Western clothes, are installed in each city and province. Graduates who majored in clothing and textiles are posted in institutes or apparel factories. Their job is designing, patternmaking and sewing for their customers. Most of them are women and in good state of economic conditions. The North Korean clothing industry has been the core national industry that has developed based on overseas demand form the mid 1980s. The standard is that of South Korea in the early 1980s. In 1999, trade of North Korean textile products with trade counterparts such as Japan and China was $1.3 million in exports and $1.27 in imports. Of this amount the export takes up 25.4% of the total exports in North Korea. However, fundamentally even in sectors that are irrelevant to politics such as the fashion clothing industry, trust between the South and North should be a prerequisite. Only through this can exchange between North and South and economic cooperation contribute towards the reunification.
