(The) effect of foreign direct investment (FDI) on economic growth (GDP) : Case of Ecuador

MUNOZ, VASQUEZ EDISON DANIEL 아주대학교 Graduate School of International Studies Ajo 2017 국내석사

Foreign Direct Investment (FDI), theoretically speaking, is one financing source to accelerate economic development. It helps to improve the welfare of a country throughout the generation of employment, transfer of technology, capital accumulation, etc. However, several empirical studies have suggested that there is either a negative or positive impact on the economic growth. Those different results can be explained because of the particular characteristics of each study such as the period of time, methodologies, type of data, etc. Despite the facts that Ecuador's economy was ranked as eighth in the largest economies in Latin America with an average of 4.6% of GDP Growth during the period from 2000 to 2006, the development of the country is restricted. For instance, Ecuador adopted the US dollar as a national currency, the economy is highly dependent on oil exportation and a populist and protectionist governmental framework was imposed during the last 10 years. Consequently, there are few incentives for foreign investors and competitive disadvantages due to the cost opportunity in comparison to similar economies in Latin America. This research conducts a theoretical and empirical approach. It uses an adapted estimated model and econometric techniques in order to understand the positive contribution of FDI to the economic growth specifically in the case of Ecuador. In addition, it provides a precise interpretation of its interaction with human capital, capital accumulation and transfer of technology. Finally, this research provides enough evidence and suggestions to modify governmental policies to promote foreign direct investment as a way to develop the country.

Blind source separation combined with beamforming

Munoz, Rodrigo C. Jr Graduate School of Paichai University 2005 국내박사

Blind signal separation (BSS) is known as a powerful tool for enhancing noisy speech in many real world environments. Normalized Multichannel Blind Deconvolution (MBD) algorithm for non-stationary convolutive mixtures is one robust method in solving BSS. This MBD algorithm normalizes the signal spectrum in the frequency domain to provide faster stable convergence and improved separation without whitening effect. Nonholonomic constraints and off-diagonal learning are another way to further improve the MBD though they introduce some deteriorating effect on the signal. This thesis introduces the BSS of convolultive mixtures of acoustic signals especially speech, the technique of beamforming, and the combination of the two systems. The properties and structure of the blind source separation algorithm is discussed. Then the performance of the blind signal separation is further improved using directional information of sources. The beam patterns of the null-beamformer (NBF), the fixed-beamformer (FB), BSS, and their combinations are investigated. From various forms of non-adaptive beamformer, it shows that the NBF gives a better and sharper beam pattern compared to the conventional FB. It also shows that directional null reduces mainly direct parts of the unwanted signals whereas BSS reduces reverberant parts as well as direct parts. With this regards, faster and improved separation can be obtained by removing the direct parts first by a non-adaptive beamformer and then output signal is cascaded into a BSS system to further cleanse the desired signal from interference. Simulation results using a real-world recording confirm a good improvement in the speech quality with the implementation of the algorithm and its usefulness in real world applications.

Current state of the access to mobility assistive devices and its services in the Dominican Republic

Munoz Collado, Rosanny Araysy Graduate School, Yonsei University 2024 국내석사

In many low and middle-resource settings, the Assistive Technology (AT) provision is highly fragmented and almost nonexistent, with limited purchasing and no service delivery systems. Despite the existence of a legal framework on disability in the Dominican Republic, there is no comprehensive source of data on the availability of mobility assistive technology (MAT), and there is a significant capacity gap between public and private service providers. The purpose of this study was to investigate the current status of access to mobility assistive devices and related services in both private and public rehabilitation centers in Cibao Norte, Dominican Republic. To this end, a self-administrated survey was conducted targeting people with physical disabilities, who were currently outpatients of 2 public rehabilitation centers and 2 private rehabilitation centers, in other to gather information about the use, unmet needs, barriers to access and level of satisfaction with the mobility assistive devices and related services. A total of 102 individuals were surveyed. As a result of the study, there was a statistically significant difference between the prevalence of self-reported unmet need for mobility assistive devices and the overall use between the two samples (p=0.003 and p=0.007, respectively), with the Public sample reporting both more unmet needs and less use. Canes/ sticks and manual wheelchairs were the most frequently reported mobility assistive devices (MADs) in both samples. Regardless of the group, the most common source of funding for mobility devices was the private sector, with the cost being borne by the users or a family member. Those who received services from the private institution exhibited higher levels of satisfaction across all categories compared to those who received services at the public institution. Furthermore, the Mann-Whitney test yielded significant findings indicating notable variations in satisfaction levels across: satisfaction with the mobility assistive device (p=0.000), satisfaction with the assessment and training (p=0.001), satisfaction with the repair, maintenance and follow-up (p=0.001), AT is suitable for your home and surroundings (p=0.004) and AT helps you to do what you want (p=0.039). Currently, the accessibility, the user’s satisfaction, and the metneeds for mobility devices and services in the Dominican Republic vary depending on the nature of financial resources. In particular, the lower satisfaction and usage rates for public services compared to private services is a factor limiting universal accessibility to mobility devices for disabled users. Therefore, the establishment of a national-level strategy and action plan to improve accessibility and usability of mobility assistive devices is required.

Efficient mitigation schemes for co-channel interference in indoor visible light communication systems

GABRIELA ALEJANDRA ROMERO MUNOZ 경희대학교 대학원 2019 국내박사

In this dissertation, efficient mitigation schemes for co-channel interference (CCI) are proposed to improve the bit error rate (BER) performance of indoor visible light communication (VLC) systems. Due to multiple light emitting diodes (LEDs) are installed in indoor environments for lighting purposes, multiple-input single-output (MISO) schemes can be implemented in VLC systems to increase the transmission capacity and likelihood of the signal reception. However, the interference between adjacent LEDs known as CCI must be considered when VLC uses LEDs, which act as optical transmitters, to transmit unique data over the same frequency resources and the photodiode (PD), which acts as an optical receiver, obtains the different signals over its physical area; the signals can seriously interfere with each other to the point that the receiver cannot recover the information, obtaining useless data. Because the quality of communication link degrades as CCI increases, VLC must overcome CCI to provide a reliable communication throughout the room. VLC is considered as a promising complementary technology for existing wireless communications, which have a shortage of spectrum resources, because of its multiple advantages like it uses the lighting infrastructure for transmitting data using white LEDs, does not interfere with radio frequency (RF) communications and can be installed in electromagnetic interference sensitive areas, such as hospitals, airplanes, and so on. Since VLC can alleviate the increasing data traffic, increase the capacity transmission and prevent loss of connectivity, it can provide service in internet-of-things (IoT) networks, which are applied in healthcare, smart indoor environments, etc., to improve the daily life; for instance, IoT devices can communicate with each other or personal devices, e.g. smartphones, tablets and laptops, to control, monitor, track or locate a particular object. In order to deal with CCI, the proposed schemes are based on transmit diversity and inter-lighting interference cancellation (ILIC) to avoid or mitigate CCI, depending on the data transmission. Employing transmit diversity techniques, the LEDs cooperate to transmit data, which is encoded by space frequency block code-frequency switched transmit diversity (SFBC-FSTD) encoder. At the receiver side, there are no interference signals because each LEDs transmit an encoded data; it means that the signals transmitted by the cooperative LEDs are useful to decode the desired information. Therefore, CCI is avoided by converting the interfering signals into desired signals. By contrast, the signals interfere with each other at the receiver side when the LEDs transmit different data to increase the transmission capacity. While the PD receives the signals with different powers, the signals are detected by ILIC, which decodes the high received power signal and reduce CCI in the low received power signal before decoding. This dissertation presents efficient mitigation schemes for CCI in indoor VLC systems to provide reliable communication throughout the room; the proposed schemes avoid or mitigate CCI, depending on the data transmission. It is organized as follows. Chapter 1 gives a briefly overview of VLC system including advantages, challenges and applications, and depicts the motivation of the research and the contributions obtained from the proposed schemes through computer simulations. Chapter 2 introduces the most important parts of a basic VLC system such as optical channel and optical modulation, and describes an indoor MISO-VLC system, which is composed of multiple LEDs and a PD, that is used to evaluate the BER performance of the proposed schemes in presence of high CCI, i.e. the PD position is in middle of the LEDs, determining the signal-to-noise ratio (SNR) or the received optical power required to the target BER = 10^-3, which is the minimum BER for basic communication. Chapter 3 describes the decentralized and centralized cooperative transmission, which are proposed to avoid CCI. The proposed schemes are based on space frequency block code-frequency switched transmit diversity (SFBC-FSTD) to encode the data in spatial and frequency domain. Employing transmit diversity techniques, the LEDs cooperate to transmit the SFBC-FSTD vectors in centralized and decentralized way and the PD requires them to decode the data. In centralized scheme, the LEDs have to communicate with each other to perform code allocation because each cooperative LED transmits a SFBC-FSTD vector. By contrast, the LEDs do not need to communicate with each other before transmission when the decentralized scheme is used because the LEDs send its own random data, which contains the SFBC-FSTD vectors. The proposed schemes overcome CCI because the interfering signals are converted into desired signals and thereby improve the BER performance, providing spatial diversity gain. Chapter 4 describes two improved versions of inter-lighting interference cancellation (ILIC), enhanced ILIC (E-ILIC) and cooperative ILIC (C-ILIC), which are proposed to mitigate CCI when the LEDs transmit unique data to increase the transmission capacity. The proposed schemes are based on ILIC, which improves the performance of a MISO-VLC system when the signals are received with different power because there are high and low received power signal, to reduce CCI in low received power signal. Owing to the average BER performance of ILIC changes with the PD position due to the received power ratio between two signals is different at each position, E-ILIC and C-ILIC are used to receiver the signals with different power whose power ratio complies with the threshold by applying power allocation so that the LEDs transmit unique data with different powers and cooperative transmission so that the LEDs transmit a composite data, which contains two data, with equal powers, respectively. Therefore, E-ILIC and C-ILIC achieve the best average BER performance of ILIC, regardless of the PD position because the received power ratio between the signals is two, while increasing the transmission capacity. Finally, Chapter 5 provides a summary of the proposed schemes, which avoid or mitigate CCI, depending on the data transmission, and overcome link blockages when the decentralized cooperative transmission and cooperative-ILIC are used because the receiver can be recovered the data by receiving at least one received link, and concludes this dissertation.

"When I heard about the march": Testimonies and participatory archiving in peacebuilding

Munoz Proto, Carolina City University of New York 2013 해외박사(DDOD)

This dissertation studies the Memoscopio archive and its collection of testimonies about the 2009 World March for Peace and Nonviolence (the March). This collection came into existence during 2009 and 2010 through a participatory archiving project carried out by a team of peace advocates and researchers in collaboration with March participants. The March was a transnational and decentralized campaign that promoted peace, nonviolence, and justice through activities in 600 cities, social media, and a three-month march around the world. Through the case of Memoscopio and the March, this dissertation explores the personal and cultural meanings of transnational peace marchers in a globalized and digital world. In addition, it analyzes the transformatory uses of testimonies, and the ways in which March participants rejected normalized violence and injustice through accounts that release their memories and imaginations about themselves, peace marches, and peacebuilding. The analysis suggests that the psychological dimensions of peace marches, which remain under-studied, go well beyond the collective locomotion of people who oppose war. In this sense, transnational peace marches can be productive sites for research on the evolving meanings of protest and peacebuilding in the 21st century. Methodologically, the dissertation explores, and reflects on, participatory archiving as an approach to producing critical, relevant, and collectively owned knowledge.

Quality Improvement to Assess and Audit Complexity in Translational Research

Munoz Soto, David A ProQuest Dissertations & Theses The Pennsylvania S 2015 해외박사(DDOD)

The large gap between proven clinical knowledge and its implementation in clinical practice is a pressing challenge faced by the health community. It has been estimated that adults in the U.S. receive only about half of their recommended care. This is in part, due to the complexities and current inability of translating knowledge to effectively impact health outcomes. Moreover, the lack of understanding of the complexities involved in translational research have resulted in a poor allocation of resources. As an effort to accelerate the rate at which new discoveries become clinical practice, the National Institutes of Health (NIH) explicitly made translational research a central priority and has invested heavily in developing an infrastructure through the Clinical and Translational Science Awards (CTSAs). The arc of this dissertation is in alignment with this priority. Translational research experts have argued that the existing models in translational research have not been able to fully capture the complexities, dynamisms, and fragmentations of this long process. In response, data-driven tools and robust frameworks are expected to help analyzing, and hence, accelerating this knowledge translation. These frameworks are needed for assuring an efficient and effective decisionmaking process that support the tactical and strategic allocation of healthcare resources. Although Quality Improvement (QI) approaches have been found to be promising to solve a wide variety of problems in healthcare, their implementation in translational research has not been fully explored. Moreover, in healthcare fields, QI has been mostly associated with Lean and Six Sigma techniques. However, in order for QI techniques to address translational research challenges, a wider QI scope is needed. In response to these challenges, a comprehensive QI research approach is used in this dissertation to provide frameworks that inform healthcare decision makers, and hence, have a positive impact on translational research. The frameworks presented are applied to different case studies that use them to generate evidence for professional applications. The main body of this dissertation is divided into three parts. The first part proposes a combined Quality Function Deployment (QFD) and Analytic Hierarchy Process (AHP) framework for assessing the complexity of translational research. Specifically, this framework is used to identify and quantify the importance of the different operational steps and corresponding technical requirements along the translational research process. This framework was applied to a case study of a primary care-based weight control intervention. The second part proposes a Social Network Analysis (SNA) approach for evaluating collaboration and multidisciplinarity networks. The evaluation includes the identification of collaboration patterns, leaders, influencers, bridgers of knowledge, and research clusters. A case study that analyzes collaboration on obesity research at the intra-institutional level is presented to illustrate the potential benefits and applicability of this framework. Finally, a goal programming (GP) model and a costeffectiveness analysis (CEA) approach is proposed to guide the proposal selection problem and estimate the potential impact of healthcare interventions respectively. Specifically, a GP model was developed for the proposal selection of a CTSA's hub from a strategic perspective. Additionally, a model for rapid estimation of impact is applied to an early detection of intervention of Parkinson's disease. Lastly, a combination of these two techniques is modeled to incorporate cost-effectiveness measures into the proposal selection problem. These studies cover relevant topics that aim to support the understanding of translational research and offer pathways for a more efficient translation of new discoveries into clinical practice through QI research approaches.
