The Cambodian economy has experienced rapid growth in recent decades, with its gross national income per capita increasing to US$1,119 in 2018 from US$ 337 in 1995. A key driver of this remarkable economic growth is the substantial increase of garment exports to high-income markets such as the European Union (EU), the United States, Canada, and Japan. However, Cambodia's economic prospects are becoming increasingly uncertain after the EU announced in February 2019 its intention to launch a procedure to temporarily withdraw tariff preferences granted to Cambodia under the "Everything But Arms" (EBA) arrangement, over concerns related to serious human and labour rights violations in the country. In response, the Cambodian Ministry of Economy and Finance said that the government has reserved around US$3 billion to cope with the possible suspension. The possible withdrawal of the EBA has been recognised as a shock capable of triggering an economic crisis. How important is the EU market for Cambodian exports? How did garment exports to the EU become so important to the Cambodian economy? What impact have exports to the EU had on trade, investment, and jobs in Cambodia? Why does the EU intend to suspend the EBA for Cambodia? Answers to these questions will shed light on the implications of the EBA withdrawal for Cambodia.

학위논문(박사)--서울대학교 대학원 :농업생명과학대학 농생명공학부,2020. 2. 최영진. ; 현대사회에서 인간의 평균수명은 지속적으로 증가하고 있으며, 이에 따른 행복과 건강에 대한 관심이 크게 증가하고 있다. 전세계적인 이러한 현상은 자연스럽게 진단기술의 개발을 촉진시켰다. 특히, 바이오센서는 현장 진단용 기술로 큰 기대를 받고 있다. 분석물을 생체 인식 시스템을 이용하여 분석하는 장치인 바이오센서는 일반적으로 감지기, 변환기, 신호 분석 시스템 세 가지 요소로 구성된다. 바이오센서의 목표는 생물학적인 감지를 높은 민감도와 선택도로 구현하는 것이다. 의료 및 현장검사(point-of-care testing, POCT) 용을 시작으로 발전한 바이오센서의 진단기술은 식품안전, 군사, 환경 모니터링 등의 다양한 분야로 확대·응용되었다. 식품안전 분야에서의 바이오센서의 개발은 큰 어려움이 존재하는데, 그 이유로는 식품이 가지는 매우 다양하고 복잡한 matrix 때문이다. 즉, 식품은 종류도 다양하며, 그 안의 구성 matrix도 매우 복잡·다양해서 바이오센서의 작동을 어렵게 한다. 따라서, 식품 안전분야의 바이오센서의 개발은 식품에 대한 이해를 토대로 연구개발되어야 한다. 즉, 식품안전분야에서는 전처리 과정이 적으며, 식품의 matrix에 영향을 많이 받지 않으면서, 많은 양의 샘플을 처리할 수 있는 현장적용이 가능한 바이오센서의 개발이 필요하다. 또한, 현장 적용에 최적화되기 위해서는 장치의 소형화, 자동화, 간편화 등이 동반되어야 한다. 금 나노입자의 응집을 이용한 비색반응은 육안으로 신호분석을 할 수 있어서 특별한 분석장비가 필요하지 않다는 이유로 현장적용에 적합한 기술로 평가받고있다. 하지만 이 반응은 약 1010 ea/mL이상의 농도의 금 나노입자를 이용해야만 하는 점과 분석물의 감지와 신호분석이 동시에 일어나는 특성이 맞물려서 민감도가 좋지 않다는 한계점이 존재한다. 이에 따라서, 이중기능링커(bi-functional linker), 동일한 의미인 스위치어블 링커(switchable linker)를 사용한 새로운 금 나노입자의 응집 시스템은 금 나노입자의 응집과 분석물과의 반응을 서로 독립시켜서 이러한 문제점을 해결함으로써, 현장 적용에 적합한 바이오센서로서 대두되었다. 본 연구에서는 이중기능링커를 활용한 금 나노입자의 응집반응으로 토마토에서 살모넬라 균(Salomonella Typhimurium)을 간단한 조작으로 45분 이내에 10 cells/mL 이하로 검출할 수 있음을 보임으로서 식품산업현장에 적용가능성을 입증하였다. 또한, 1/10 희석한 serum에서 단백질 바이오마커인 prostate-specific antigen을 100 fg/mL의 수준까지 검출 가능함을 보임으로서 다양한 분석물에 적용할 수 있음을 보였다. 마지막으로, 3-way valve chamber와 주사기 필터를 적용한 소형화된 검출 장치를 통하여 살모넬라 균(Salomonella Typhimurium)을 검출함으로서, 이중기능링커의 금 나노입자 응집반응 시스템이 현장에 적용할 수 있음을 보였다. 물론 본 전략이 식품현장에서 사용하기 위해서는 자동화, 대량화, 안정성 등의 문제를 해결해야 할 것이다. 하지만, 간편하고, 민감하며, 매우 빠르게 분석물을 진단할 수 있다는 점에서 현장적용의 잠재력이 높다고 판단된다. ; The average human life span is continuously increasing as are efforts worldwide to improve health and happiness, which has spurred the development of diagnostic technologies. In particular, great advances are being made in biosensors that enable on-site diagnosis. Biosensors, i.e., devices that examine analytes using biometric systems, typically consist of three components: detectors, transducers, and signal analysis systems. The goal for biosensors has evolved to enable biological sensing with high sensitivity and selectivity. The use of biosensor diagnostic technology developed for medical and point-of-care testing has been expanded and is now applied in various fields, including food safety, the military, and environmental monitoring. The development of biosensors in the field of food safety presents significant challenges because of the very diverse and complex matrices that characterize food. In other words, foods come in many varieties, and their composition matrices are complex and diverse, which makes it difficult for biosensors to operate. Therefore, biosensors in the field of food safety must be researched and developed based on our current understanding of food. Such a biosensor must require minimal pretreatment and be able to process a large number of samples without being affected by the food matrix. In addition, to be optimized for field application, the device must be miniature in size, automated, and simple to use. Colorimetric methods that employ the strategy of gold nanoparticle (Au NP) aggregation have been determined to be suitable for field application because they can perform signal analysis using only the naked eye and require no specialized analytical equipment. However, these methods are limited by their poor sensitivity for the following reasons: First, color can be distinguished by the naked eye only when using Au NPs at a concentration of about 1011 ea/mL or more. Second, in general, Au NPs facilitate both detection and signal analysis. As a result, high concentrations of Au NPs require high concentrations of analytes for signal analysis. Accordingly, a novel Au NP aggregation system is proposed that uses a bi-functional linker (BL), which has the same function as a switchable linker, and thus solves this problem by separating the signal analysis step from the analyte detection step by the aggregation of Au NPs. In addition, a BL-based assay, which has advantages such as simple operation and requiring no washing step, has emerged as a biosensor suitable for application in the food industry. In this study, the aggregation strategy of using Au NPs as a BL showed that Salmonella Typhimurium could be detected in tomatoes at concentrations of less than 10 cells/400 μL within 45 minutes through simple manipulation. This indicates that this strategy is applicable to the food industry. In addition, prostate-specific antigen, a protein biomarker, was detected at a concentration of 100 fg/mL in a serum diluted to 1/10, which indicates that this strategy could be applied to various analytes. Finally, by detecting Salmonella Typhimurium using a miniaturized detection device with a 3-way valve chamber and a syringe filter, the BL-based assay could be applied in the field. Of course, to qualify this strategy for use in the food field, issues related to automation, sample bulk-up, and stability must be addressed. However, the potential for field application is high due to this strategy's simplicity, sensitivity, and rapid diagnosis of analytes. ; Chapter I. Introduction: 1 I-1. Biosensors 2 I-1-1.

Nowadays electric propulsion has become a valid alternative to mechanical propulsion for large ships that require high speed. The electric propulsion advantages are well known and widely documented in the literature: higher dynamic performance of the electric propulsion motors; internal combustion engines separation from shafts; increased flexibility in space/zones subdivision; increased efficiency through the modulation of number of running generators; noise and vibration reduction; increasing in automation, with a consequent crew reduction. The use of electric propulsion along with the progressive increase, in number and power, in electrical loads used for ship services, led to the development of the All Electric Ship (AES) concept. Over the last years, the All Electric Ships (AESs) concept has begun to be adopted by the most important Navies, principally by the U.S. Navy, giving a boost to the technological research. An AES is a ship where all onboard electrical loads (including propulsion) are powered by a single electrical system, called Integrated Electrical System (IPS). The IPS requires careful design and management in order to ensure both high Power Quality standard and the continuity of the service. With the technological progress, the shipboard electrical systems have changed considerably, rising from few MW of installed power to values of the order of hundred MW, both in cruises and military ships. Especially in military vessels, considering the number of special devices that are present on board (weapon systems, communication equipment, radar, sonar, and missile guidance systems), a performing and reliable electrical systems is required. Moreover, it is necessary to notice that some of the new electrical pulsed loads specific to military applications (e.g. radar, electromagnetic launchers, etc.) together with electric drives for propulsion engines can cause strong disturbances to the system, thus causing the malfunction of other electric utilities that may endanger the continuity of the service. The penetration of power electronics converters is the main issue for the contribution of harmonic distortion in AC grids, which must be limited not to increase system power losses, and to allow the correct operation of system and user devices. Standards dictate the maximum admissible values of the total voltage harmonic distortion and of the individual harmonics amplitudes, as a function of the rated system voltage. The relatively limited short-circuit power available on board also exposes the IPS to significant voltage sags and flickers caused by switching and/or intermittent loads. In this scenario, DC electrical distribution systems can be very attractive, thanks to their intrinsic immunity to harmonic problems. If DC micro-grids are interfaced to AC networks by means of Front End Converters (FECs), both AC/DC grid decoupling and considerable AC-side harmonic distortion reduction can be achieved. In addition, they simplify the power supply of converter-fed loads and the interfacing of storage systems. The latter can perform several tasks, including ensuring power supply in case of AC grid loss, peak-shaving and levelling pulsating loads further improving both the quality and the continuity of supply to DC islands loads. In the light of the above, it is evident that the electric power system is of primary importance for a modern ship. Moreover, if high-performance is required, careful analysis of the disturbances in the power system is mandatory. In fact, in order to achieve a reliable and performing power system, together with a high-Power Quality, it is necessary to assess this situation and propose guidelines to be observed for the solution of various problems. The definition and evaluation of possible IPS architectures should take into account AC/DC protection devices in order to carry out an integrated analysis of the system. Different MVAC/MVDC electrical distribution layouts coupling with all-electric or hybrid propulsion (electric/diesel/gas turbine) needs to be accurately investigated to show its advantages in terms of reliability, safety and quality of power. The thesis focusses on the Naval Smart Grid (NaSG) research project completed in partnership with the University of Trieste and the Polytechnic University of Milan. The aim of the research is to produce useful results for the design of a new ship, equipped with the following innovative features: modular power system; subsystem flexible integration; efficiency improvement; security improvement; new weapon systems; survivability improvement and high Power Quality standard. The main focus was the study of methodologies/solutions able to improve and define the onboard Power Quality (PQ). The research project reports Power Quality analysis about aspects of continuity of service, harmonic disturbances, pulsed power loads impact on the system, electromechanical transient evaluation and use of power and energy storage systems. An exhaustive investigation was carried out on system architectures in frequency domain to identify resonances and non-linear loads to detect disturbance frequencies. Moreover, the guidelines for the correct coordination of all the elements of the power system design affecting system performance (protections, converters, control systems, energy storage systems, etc.) are reported. A brief abstract for each Chapter is reported. Chapter 1 and 2 - Overview of Electrical Naval Systems and Integrated Power System in Military Ships The chapter reports the complete state of the art on naval electrical system and a brief description of naval classification, showing technological improvements and historical evolution. Details about electric propulsion, electrical generation on board, energy distribution and network layout are carried out. A complete description of the main IPS military ships with their own architecture and features is reported. Chapter 3 - Methodologies for Harmonic Disturbances Analysis and Power Quality (Service Continuity) In the field of Power quality (harmonic content, asymmetries, voltage sags, power factor), methodologies applied for the analysis/detection of harmonic disturbances are reported with an overview of electrical systems dependability in order to evaluate the service continuity of the system. Harmonic distortion could affect equipment on shipboard causing its outages, consequently, in an island system, power distribution network should ensure high re-configurability after faults, damage or untimely switch off. However, the increased interest in system's safety and resilience generates, in turn, an increase in design burden necessary to analyze the consequences of faults and demonstrate the system's compliance with the relevant regulations. The chapter presents the models and calculation code used for simulation activities. A Simulink model for time domain analysis and for time varying non-linear load, as well as a Fortran model for harmonic domain are described. Chapter 4 and 5 - Characterization of a military aircraft carrier and Aircraft Cavour – Measurement campaign A measurement campaign onboard the ship Cavour was carried out with the aim to characterize the relevant electric loads on board military vessel and to validate the models of the system's components to be used. The analysis of data collected, allows to model the behavior of loads in terms of time and frequency domains, thus permitting their use for the required studies. Some specific electrical loads, such as new electrically pulsed loads specific for military applications (e.g. radar, electromagnetic launchers, etc.) with high distorted current absorption were identified. Their characterization was carried out in order to define their contribution to harmonic disturbances and their impact on the network. A model validation based on a measurement campaign is carried out. Chapter 6 - A New layout for an Integrated Power System Naval Unit-All Electric/Hybrid Different IPS architectures are defined: a full MVAC (Medium Voltage Alternate Current) power system, a hybrid MVAC plus MVDC/LVDC islands (Medium/Low Voltage Direct Current) and a MVAC 50-60 Hz, with a hybrid (electric/diesel/gas turbine) propulsion. In the architecture of the latter, the power of the installed engines is much lower than the first two cases. Chapter 7 - Network Equivalents in Harmonic Domain The needs to easily represent a complex network with high accuracy, lead to the development of a methodology based on aggregation of loads, creating a simplified network to carry out harmonic analysis. Different equivalent network models have been proposed that show their accuracy, through network impedances, and compare them with the overall representation of the network. The influence of cables was also studied. The best radial equivalent network was identified. Chapter 8 - Harmonic Analysis In order to propose appropriate solutions designed to improve power quality, the study of system impedance and power systems in frequency domain were studied. This analysis, carried out on the basis of the schematics and data load obtained in cooperation with the IT Navy, revealed some criticalities in the frequency range for both the systems architectures. As to full MVAC (Medium Voltage Alternate Current) power system and hybrid MVAC plus MVDC/LVDC islands, the aim was to evaluate whether or not the inclusion of capacitors (on shore, for power factor correction in shore connections) or filters (onboard, to reduce harmonic disturbances produced by propulsion systems) cause special issues, because of the high power of installed propulsion engines. Moreover, the advantages of DC island on electrical distribution in order to ensure high reliability and quality of service, in addition to the need to increase the efficiency of the ships' power systems are highlighted. For the MVAC 50-60 Hz layout, the goal is to show how the use of hybrid (electric/diesel/gas turbine) propulsion where the power of engines is significantly reduced as compared to previous cases could solve some issues relating to power quality aspects. Chapter 9 - Reliability Analysis Preliminary studies about dependability, re-configurability and some top-events relevant for the vessel, were evaluated for all electric MVAC/MVAC "hybrid" models. The analysis of electrical disconnection of load areas due to a fault or an untimely tripping of the switches caused by harmonic disturbances was carried out. Chapter 10 - Three-Phase Short Circuit Analysis For MVAC 50-60 Hz Layout Preliminary evaluations were performed by analyzing the system within the perspective of given faults to perform system analysis in both permanent and short-circuit conditions. To highlight possible protection issues, the steady state condition and the three-phase short-circuit faults were studied and simulated under different load conditions for the MVAC architecture plus rotary converters, with hybrid (electric/diesel/gas turbine) propulsion.

All inter-state organisations are shaped and challenged by the changing engagement of their major stakeholders, the difficulties associated with consensus-based reform and consolidation, the inevitable gap between expectations and feasible delivery, and the evolving strategic environment within which they exist. Where ASEAN is concerned, the mutually reinforcing effects of such challenges will test the East Asia Summit (EAS) and threaten its peak position in the ASEAN-led regional architecture in the coming years. How ASEAN member states and ASEAN itself respond will help determine the EAS' future status.
