While the integration into global value chains has garnered attention as a rural development strategy, less is known about why some integrations are successful while others are not. This study draws on rent theory and on empirical examples from Jinju and Nonsan, the two biggest strawberry production regions in South Korea, to explore the mechanisms of Jinju creating and exclusively retaining monopoly rents from the exports. Based on five months of fieldwork and in-depth interviews with stakeholders, the findings show that a producer-driven chain integration into the overseas markets was possible in Jinju due to the natural barriers to entry based on an exportable variety, as well as the region's climate conditions being suitable to the variety. Moreover, the farmers have attempted to retain the monopoly rents and extra profits from public supports by associating producers. The horizontally associated farmers stabilized their positions by enhancing their bargaining power against exporters, as well as by managing access to the public supports by controlling memberships.

In this study was made the flutter analysis for the export model of Firefly(Bandi-ho), the small canard aircraft. Stiffness model based on internal load generation finite element model was generated. Mass model based on the weight DB for weight control was generated. Aerodynamic model based on Doublet Lattice Method was generated. Preliminary flutter analysis was made. Based on it, major vibration modes are identified and experimentally obtained via the ground vibration test. The obtained normal mode frequencies were used to correlate the finite element model. Flutter analysis was made again and major flutter mechanisms were summarized. The most important flutter root was identified as a coupled root between rigid body roll mode and anti-symmetric wing pitching mode.

U.S contains the best technology, man power, and big investment in space. It considers space as not only a science and technology related area, but also as an industry and national security related area. Korea's space policy focuses on the development of space systems such as satellites and launch vehicles. Space policy systems of the two countries are also different, causing some discrepancy in mutual interest when we talk about cooperation with the U.S. This study introduced U.S space policy framework and compared it with Korea's policy. It is meaningful in that we can find an effective way of cooperation between two countries.

The Korea-USA FTA was activated in 2012 and evaluated highly on market-opening among FTA agreements which the Korea government has signed. This paper empirically examines the impact of the Korea-USA FTA on the Korea content industry trade performance with USA. Using ANOVA analysis, the study tested primarily whether there are difference in content exports and imports in a korea-US trade between before and after of Korea-USA FTA in 2012, the year of the entry into force of Korea-USA FTA. Using content industry exports and import data over the period 2007-2015, we find that Korea content export to US after 2012 is significantly different from one before 2012, and there is no difference in import. Based on a regression analysis, we also tested the impact size of Korea content export performance in Korea-USA FTA. The result is that coefficient of FTA dummy variable is not significant, meaning that even though there are some difference in korea content export to US between before and after of Korea-USA FTA, the Korea-USA FTA agreement itself is not a key factor which increase the Korea content export volume to USA market.

This thesis describes the key elements for efficient customs clearance system which can facilitate flow of maritime container cargo in the pier area of Busan port, on the basis of considering great changes on international trade environment, development of customs clearance system, variation of commercial container traffic, and diverse views originated from field experience in the distribution industry. To facilitate the flow of maritime containers, reform plan of bonded-transportation and import declaration is proposed to relieve the customs restriction during the days from discharging cargos to taking them into bonded warehouse. Also, various plans to strengthen maritime security, such as customs exam of high-risk export cargos in loading port, pre-declaration of transit container replacement, container tracing system, are proposed to improve Busan port's competitiveness in safety.

The purpose of this study was to examine ways of ensuring the efficiency and stability of import-export logistics in our country by introducing an advance presentation system of vessel manifest. This advance presentation system of vessel manifest has already been introduced in the United States, the EU and China whom our country has actively traded with, and the reinforcement of logistics security is a global trend. Under the circumstances, the introduction of the advance presentation system of vessel manifest is required to assist exporters to properly respond to changing trade practices as early as possible, and it's also necessary to exercise stricter control over an import criminal cargo. Our country should urgently introduce the advance presentation system of vessel manifest that is up to global standard, and the establishment of an internet based manifest consolidation and presentation system and the introduction of an export inspection system of port of loading are requested as well. If all the systems are introduced and work properly, that will make a great contribution to the efficiency of import-export logistics in our country.

This study aims to predict the likely effect of economic sanctions on North Korea by examining case studies of Iran and Iraq. While UN sanctions against Iraq had immediate negative consequences for society, such as causing famine and reinforcing the authoritarian regime, sanctions against Iran had some productive consequences after they were reinforced by the U.S. and EU in significantly reduced oil exports and government expenditure, which in turn led to regime change and willingness to negotiate nuclear programs for economic recovery. Apart from these distinct differences, sanctions in both countries caused high inflation, shortage of necessary supplies, and increased unemployment. Case studies of Iran and Iraq also reveal that the sanctions disproportionately affected women and children, which implies that the recently reinforced economic sanctions of the U.S. and China against North Korea will cause more suffering of similarly socially marginalized groups in North Korea.

Blockchain is a technology that secures integrity and transparency by distributing and storing transaction details within multiple node networks. Recently, research is being conducted to secure integrity by applying blockchain to Bill of Lading (B/L documents) of monetary value. In this paper, we study a blockchain-based bill of lading system to improve usability. The shippers register the issued bill of lading on the blockchain, and banks in each country read it to conduct L/C transactions. The consignees receive the goods after completing certification with a quick response code (QR) containing the bill of lading information. Through this, shippers enjoy merits in that they can shorten the time and cost of sending shipping documents by mail and prove the integrity of the documents. The consignees have the advantage of being able to check the documents at the same time as they are registered and trust the transaction. Finally, on the bank side, the security of shipping documents is ensured and verification can be done quickly.

Gate operations are very important as they are the starting point for export containers and the end point for import containers as far as checking and control exercised by terminal operators are concerned. The objective of this paper is to propose the design of separated gate system in order to reduce the truck turnaround time and to distribute the truck traffic volume in port container terminal. Because of a lot of container load and unload within short term, many trucks have to pass the gate at a time. This study suggests the separated gate system as an efficient design for gate operation considering integration of two individual berth.

Rare earth alloys and compounds are the raw materials for the manufacture of advanced materials. Although domestic monazite ores have been found, there are some difficulties in recovering rare earth from these ores. Rare earth ores are found in few countries and these countries put an embargo on the export of rare earth ores for the protection of their industry. We gathered some information on the hydrometallurgical and pyrometallurgical processes to recover rare earths from bastnasite, monazite, and xenotime which consist of 95% of the total rare earth ores. Since rare earth with the purity more than 6N is needed for use in advanced materials, some separation methods such as fractional crystallization, precipitation, ion exchange, and solvent extraction were introduced.
