이종 망 환경에서 멀티미디어 서비스의 QoS를 보장하는 것은 3GE 시스템 개발을 위한 중요한 이슈이다. 이동 단말기가 이종 망간의 이동 시 끊임없는 서비스(seamless service)를 지원하기 위해서는 종단간(end-to-end) 협상 정보에 근거하여 사용자의 QoS를 보장할 수 있는 QoS 운영 구조(QoS management structure)를 제공해야 한다. 본 논문에서는 SLA(Service Level Agreement)에 기반한 종단간 QoS 제어 방안을 제시한다. 이를 위하여, QoS 지원을 위한 SLA 제어 구조 및 알고리즘을 제안하고, 시뮬레이션을 통하여 평균 지연과 패킷 손실률을 평가한다. 제안된 방식을 적용한 시스템이 기존의 망보다 더 좋은 성능을 보인다.

The purpose of this study is to investigate whether the ECFA impacted the efficiency of banks in China and Taiwan from 2008 to 2017. This study follows Seiford and Zhu (2002), who recommend using the standard data envelopment analysis model to measure performance by increasing the desirable outputs and decreasing the undesirables. The finding was that overall technical efficiency increased from 2012 to 2017, reaching 0.575, 0.652, 0617, 0.689, 0.701 and 0.74, respectively. This result implies bank efficiency did indeed improve after China and Taiwan signed the ECFA cooperation agreement. The study found that the mean technical efficiency was 0.8756 in China, greater than Taiwan's mean of 0.3511, implying that Chinese banks experienced a greater increase in efficiency after signing the EFCA. One possible reason explored in this study is that China's economy is currently growing at the highest rate in the world, and the banks' efficiency has benefited from greater economic growth. This suggests that cross-strait sustained negotiations to consummate an agreement on trade in the services will be a very important mission in the future. This result also provides significant evidence suggesting that not accounting for undesirable output while estimating the evolution of the model may seriously distort efficiency results.

China's proposal of the CAFTA (China-ASEAN Free Trade Area) in 2001 prompted a great debate about whether China was a trade competitor of ASEAN, given their similarity in economic development levels and trade/export structures. That Beijing shifted its focus on economic cooperation from the international level to the regional level led to its proposal of the CAFTA. As the Framework Agreement (Framework Agreement on Comprehensive Economic Cooperation between China and ASEAN) showed, Beijing's careful consideration for four newer ASEAN members (Cambodia, Laos, Myanmar and Vietnam) intended not only to help all ASEAN members develop economically, but also to narrow the economic gap existing between them and the six old ASEAN members; in return, China was recognized as a full market economy, which it is not currently recognized within the framework of the WTO. The substantial rise in bilateral trade and the structural changes of the trade in goods between China and ASEAN member nations after 2001 proves that ASEAN benefited more from the CAFTA, particularly when the areas where ASEAN had the comparative advantages were designated as the priority cooperation areas between China and ASEAN. In sum, similarities existing in economic development levels and industrial structures between China and ASEAN made them natural economic competitors. However, closer studies of trade in goods of S1-7, S1-6 and S1-0 reveal that China acted as an increasingly complementary trade partner of ASEAN after 2001.

Purpose - The purpose of this study is to analyze Trade Structure after Korea and Colombia FTA, and identify its problems and suggest measures that can be taken by the government and corporations to reinforce economic cooperation. Design/methodology/approach - To improve the level of contribution of the study, an empirical analysis is necessary. However, due to limited data access, the study will approach the topic of trade relations between Korea and Colombia with various statistics and literature. Findings - First, there is an urgent need for changes in import-export goods between Korea and Colombia, as trade is focused on specific items. Second, although foreign direct investment from Korea to the Colombia is centered in manufacturing and wholesale & retail, there should be different investment strategies by industries. Third, it is necessary to reinforce commercial cooperation. Research implications or Originality - The Free Trade Agreement between Korea and Colombia entered into force in 2016. Under the agreement, both countries will eliminated all tariffs within ten years after it takes effect. Reinforcing economic cooperation with Colombia is extremely important for Korea in terms of entering and dominating Colombian market. However, there is still a lack of research on the Colombia, and corporations that aim to enter Colombian market face difficulties due to lack of information. This study analyzes the recent trends of problems of trade between Korea and Colombia and suggests solutions for boosting trade to provide proper strategic guidelines for Korea that are planning to expand to Colombian market.

The Regional Comprehensive Economic Partnership (RCEP) agreement, signed in November 2020, comes shortly after the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) entered into force and the US-China Trade War escalated. We use a computable general equilibrium model to assess the long-term effects of these three developments on income, trade, economic structure, factor returns and employment across the world, and especially in Asia-Pacific countries. The results suggest that RCEP could generate income gains that will be almost twice as large as those of the CPTPP, and that the two agreements together will largely offset the substantial negative effects of the US-China Trade War for the world as a whole. All three policy developments, but especially RCEP, will deepen East Asian production networks and will raise productivity and increase wages and employment in much of East Asia. At the sectoral level, regional trade in non-durable and durable manufactures will experience the most growth.

This paper presents several important status and strategic rotes for APEC Engineer Framework. Every technologies and engineering services are opened to the world and freely competed under WTO system after 1995. Most developed economics have been organized and coordinated each other within the common economic zone, such as EU, NAFTA for the mutual recognition agreement for professional engineers . Asia Pacific Economic Cooperation Engineers ( APEC Engineers) has been organizing to proceed the mutual recognition agreement for professional engineers among the Asia and Pacific economic including Korea from 1996. Therefore, Korean government and civil organization, such as KPEA must monitor and investigate the activities and managements of APEC Engineers.

This study aimed to review the reorganization of fisheries and the future tasks in accordance with the establishment of new fishery order in the Northeast Asian Seas. As the United Nations Convention on the Law of the Sea, which recognized the sovereign rights of Coastal States in a 200-nautical mile exclusive economic zone (EEZ), entered into force in 1994, the three countries of Korea, China and Japan ratified the United Nations Convention on the Law of the Sea in 1996 and started negotiations to establish a new fishery order consistent with the EEZ system. However, a conflict of interest occurred because of differences in fisheries between countries, negotiations many times have proceeded, resulting in the signing of fishery agreement between China and Japan in 1997, Korea and Japan in 1998, and Korea and China in 2000. Each fishery arrangement consists of a dual system of EEZ and provisional waters (middle waters, provisional waters). The two countries are engaged in mutual fishing based on coastal states in EEZ, and in the fishing operation under the principle of flag state in provisional waters. There are overlapping or ambiguous jurisdictions in the intermediate waters and provisional waters that are jointly available to both fisheries. The presence of these seas is a challenge to the establishment of a reasonable international fisheries management system for the entire Northeast Asian Seas. In this context, the challenges of the reorganization of the new fisheries order are as follows: 1) conversion to a fishery order for coexistence of fisheries, 2) expansion to an international fishery management system, and 3) establishment of a multilateral fishery cooperation system. Although the jurisdiction of their own waters has been expanded through the establishment of EEZ according to new fishery order, the need for mutual cooperation grows when considering the movement and migration of fishery resources, fishery management, fish consumption and trade. In addition to the fisheries cooperation between the governments, it is also necessary to revitalize the civil cooperation focused on fishermen who exploit fishing grounds together.

It is well recognized that the availability of prompt, effective and economical means of dispute resolution is an important element in the orderly growth and encouragement of international trade and investment. Increasingly, ADR(Alternative Dispute Resolution) including arbitration and mediation, instead of litigation in national courts, has become the preferred means of resolving private international commercial disputes. Under the situation, efforts for settlement of trade and investment disputes by ADR have been made between Korea and China through trade and investment agreements and arbitration agreement. Judging from the importance of economic exchange between Korea and Qingdao including Shandong Province, The Korean Commercial Arbitration Board(KCAB) and The Qingdao Arbitration Commission(QAC) should strengthen mutual cooperation to develop efficient methods of resolving commercial disputes arising between the two countries and to assist parties in solving those disputes through conclusion of arbitral agreement. Recently, efforts for conclusion of a Korea-China-Japan Free Trade Agreement(FTA) received strong support at Korea-Japan and Korea-China Summit Meeting held on June and July, 2003 respectively. If the conclusion of FTA among the three countries would be realized, it would promote regional trade and investment, contributing to economic growth in the Northeast Asian region. Under the circumstances, the key arbitral institutions including KCAB and QAC should consider to take the initiative in setting up tentatively called ${\ulcorner}$Joint Arbitration Center for Northeast Asia${\lrcorner}$ for which the CAMCA of NAFTA will be the good example.

항공운송산업은 그 성격상 국가간 인적 교류의 수단으로서의 중요성이 가장 높다. 항공에 의한 국가간 교류가 이루어지면 이에 따르는 파급효과 및 그 지속성이 타 산업에 비해 월등하기 때문에 항공운송산업에 대한 연구는 국제협력 또는 통합과 관련한 국가 정책은 물론 관련 산업분야의 측면에서 매우 중요하고 가치가 있다. 특히 최근 북한과의 경제교류가 활발해 짐에 따라 북한과의 연결교통망으로서 항공운송의 역할이 더욱 중요해지고 있다. 남북 정상회담이후 급격하게 증가되고 있는 남북간 항공기 운항이 정상적이 아닌 임시 직항로를 설정하여 운영하고 있고, 그 운항회수도 매년 증가하고 있는 점을 고려할때, 남북한 임시 직항로의 운영상 과제를 국제적으로 정한 기준으로 해결하지 아니한 상태에서 지속적으로 운영하는 것은 바람직하지 않다고 본다. 따라서, 본 연구는 남북한 민간항공의 협력이라는 큰 틀위에서 국가적 과업과 효과적인 항공정책의 수립을 위한 기초자료의 제공을 위해 군이통제하는 북한의 민항공에 대한 현황을 분석해 보고, 현재 남북 양국간에 진행중인 "남 북한간 민간항공기에 의한 협력 방안"으로서 "정부의 협력방안과 항공사간 협력방안"을 제시하였고 남북한간에 설정운영중인 "임시 직항로의 운영상 과제"에 대한 개선 대안으로서 임시직항로의 안전확보를 위해서 양국간에 항공관제협정을 체결하여 운영할 것을 제시하였고, 낙후된 기술 요원과 시설에 대한 지원도 하여줄 것을 제시하였다.
